    Full Text Available Background: Injury has been recognised as a preventable cause of morbidity and mortality in children. The aim of this study was to determine the aetiology, pattern and location of childhood injuries in north east Nigeria. Materials and Methods: This is a 3-year retrospective hospital-based descriptive study. The study included 114 children (77 boys, 37 girls; mean age 6.4 ± 3.2 years; range 2 months to 15 years who were admitted for various injuries in the female/paediatric surgical ward from January 2007 to December 2009. Information obtained from their case notes included demographic data, mechanism of injury, location of injury, anatomical site of injury and outcome of treatment. Results: Records for 114 children (77 boys, 37 girls; mean age 6.2 years; range 2 months to 15 years were available for analysis. The highest number of injuries occurred in the age group 6-10 years. Home was the most common location of injury among the age group 0-5 years while older children sustained most of their injuries outside the home on the street/highways. Burns from hot water was the most common injury among children aged 0-5 years while pedestrian accident accounted for the highest cause of injury among older children. Fall accounted for 20.2% of the injuries. The most common specific anatomic injury was head injury followed by limb fractures. Two mortalities were recorded (1.8%. Conclusion: This study provided useful information on the characteristics of childhood injuries in our environment. There is the need for parents and children education about the risks of injury and preventive measures in addition to legislation and policy on environmental modifications and enforcements to significantly reduce childhood injury.

    Full Text Available Marriage at its right time and with the right and self-selected person is one of the best things that can happen to a man. Unfortunately, as glamorous such a day of espousal would have been, child marriage has made it sour for child brides as most of them are forced into it, particularly in their mid-teens; thereby aborting beautiful and achievable life goals and future ambitions. This paper examines the factors inducing child marriage in the most endemic location in the country North-Eastern Nigeria and the health implications on victims. Primary data i.e. questionnaire andsecondary data from Nigerian Demographic and Health Survey (NDHS, 2008 were used. A Focus Group Discussion (FGD was also held with a group of child wives, all of who are less than 18 years. Results show that povertyand limited educational attainment are the two main cause of child marriage in the study resulting to different health problems. Recommendations were made to curb this infamous practice in Northeastern Nigeria as is a globally acceptable fact that delaying marriage until a lady is physically and physiologically mature improves her health.

    Full Text Available AIM: Adoption of western lifestyles with alterations in diet and activity patterns has been implicated in the increasing risks for cardiovascular disease in low income countries. This study investigated the prevalence of prehypertension, hypertension, overweight and obesity as modifiable cardiovascular risk factors in a low income semi-urban community in the Northeast Nigeria. METHOD: 1004 adults who were 20 years and older were recruited through a multi-stage cluster sampling technique. Definition of prehypertension and hypertension were based on the World Health Organization (WHO /International Society of Hypertension guidelines while the WHO body mass index (BMI cut-points were used to define overweight and obesity. RESULTS: The mean age, BMI and blood pressure of the participants were 41.5 ± 13.5 years, 22.2±3.73Kg/m2 and 125/78mmHg respectively. The prevalence of prehypertension, hypertension, overweight and obesity were 40.3, 25.2, 15.4 and 3.8% respectively. The Odds Ratio (95% Confidence Interval for the hypertension among the obese persons compared with normal weight and overweight participants was 2.75 (1.25–6.04 and 1.62 (0.068–3.82 respectively. CONCLUSION: Prehypertension and hypertension sequentially were the most prevalent cardiovascular risk factors in the study population. The relative risk for hypertension among obese participants was about three times that of normal weight and about two times that of the overweight participants.

  12. Phytogeography of the tropical north-east African mountains

    Directory of Open Access Journals (Sweden)

    I. Friis

    1983-11-01

    Full Text Available The tropical north-east African mountains are tentatively divided into four phytochoria, the formal rank of which is not defined. The division is based on patterns of distribution and endemism in the region. The recognition of a distinct Afromontane phytochorion is now well established (Chapman & White, 1970; Werger, 1978; White, 1978. However, there is still very little information on the phytogeography of the individual mountains or mountain systems. This study hopes to fill a little of the gap by analysing distribution patterns and patterns of endemism in the flora of the tropical north-east African mountains. The north-east African mountain system is the largest in tropical Africa (see e.g. map in White, 1978. At the core of this system is the large Ethiopian massif, around which are located various mountains and mountain chains. These include the Red Sea Hills in the Sudan, the mountain chain in northern Somalia, the south-west Arabian mountains, and the Imatong mountains of south-east Sudan. The latter are often referred to the East African mountain system (White, 1978 but. as I will point out later, they also have a close connection with the south-west highlands of Ethiopia. The paper presents some results of my study of the mountain flora of tropical north-east Africa, particularly the forest species. Where no source is indicated, the data are from my own unpublished studies.

    Full Text Available Abstract The Keffi area of North Central Nigeria hosts numerous pegmatite bodies which are related to the surrounding granitic intrusions islocated about 45 km east of the Federal Capital Territory Abuja Nigeria. Petrological investigation of the pegmatites and surrounding host rocks aimed at characterising and understanding field relations and mode of emplacement of the rocks with a view to assess their mineralisation potentials were carried out. From the field observations the pegmatites were characterised into 1 Pelitic schist-amphibolite hosted pegmatites and 2 Granitoids orthogneisses hosted pegmatites and the granites into 1 the Bakin Ayini biotite granites 2 the Angwan Madugu biotite-muscovite granites and 3 the Sabongida biotite-muscovite granites. It is clear that those discordantly emplaced in pelitic schists varied in shape and size with length and width ranging from 400-2000m and 2-20m respectively some are huge isolated sill-like and flat-lying whilst those hosted in orthogneisses are narrow ranging in length 40-1000m and width 1-4m crosscutting and vertically oriented along shear zones which suggest passive emplacement

    East Asian Summer Monsoons (EASMs) are the most important climate systems of Indo-China, the Philippines, the Korean Peninsula, and Japan due to their high impact on precipitation pattern. On the other hands, EASMs are tightly affected by El Nino which is the longer-term climate variable. In this talk, impacts of El Niño on East Asian Summer Monsoons (EASMs) in recent decades will be discussed because effects of each El Niños in recent decades are unique. Over the North East Asia, the significant high rain was observed during 2013 summer monsoon, which is a non-El Nino year, while the weak precipitation was characterized during 2014, which is a border-line El Nino year with SST higher than the threshold value over all the Niño regions. Simulation of monsoons by the Global/Regional Integrated Model Systems (GRIMs) with 0.25o horizontal resolution shows that the warming over the West Pacific causes a dry season over North East Asia. This study also takes a new approach based on the satellite data to reduce the hydrometeors amount in the model. We will discuss the matter in detail in the talk.

    Breast cancer is the leading cancer in women in both developed and developing countries. Screening mammography detects breast cancer even before a lump can be palpated, with better prognosis. The introduction of mammographic technique for screening breast cancer, despite its importance, has been slow to adopt and virtually non-existent in many parts of Sub-Saharan Africa including Nigeria. For this reason, the indications of mammography have not been well defined in our setting. The aim of this study was to audit our mammography requests, with a view to improving its application in our setting. This is a descriptive study carried out on 69 female patients who had mammography at the National Obstetric Fistula Centre, Abakaliki, from January 2014 to December 2015. Findings on clinical examination were entered in a proforma. Mammography was performed in craniocaudal and mediolateral views using the Lorad M-IV (film-screen) mammography machine. Data was analysed using the Statistical Package for Social Sciences (SPSS) version 21. All 69 patients were females. Their mean age was 42.1 ± 11 years. Majority of the patients (69.6%) were between 30 and 49 years. The commonest indication for mammography was breast lump which was found in 46 patients (66.7%). Breast pain was present in 36 (52.2%) of patients. The different Breast Imaging Reporting and Data System (BIRADS) categories were BIRADS 0: 20 (28.99%), BIRADS 1: 8 (11.59%), BIRADS 2: 9 (13.04%), BIRADS 3: 4 (5.8%), BIRADS 4: 19 (27.54%) and BIRADS 5: 9 (13.04%). Diagnostic mammography remains the commonest indication for mammography in our setting. Public awareness, poverty reduction and ready availability of mammography facilities are required to improve screening mammography in our setting.

    Full Text Available AIM: Drug promotions use multifaceted approaches incorporating hospital and office detailing by marketing representatives. Very few studies exist on their influence on doctors’ prescription pattern in Nigeria. We examined the scope and effects of marketing strategies on the prescription habits of doctors in Enugu, South East Nigeria. METHOD: This was a cross-sectional study; 210 self-administered structured questionnaires were distributed among doctors in six major hospitals in Enugu. Ethical approval was obtained from the University of Nigeria Teaching Hospital Ethics Committee, Enugu. RESULTS: There was 88% response rate, with more males than females (M:F= 2.2: 1. Most were residents-in-training/ house officers (69% while consultants were 7.1% of the group. Stickers, drug presentations/ launches and personal souvenirs were most commonly employed marketing strategies. Most doctors (60% attending a drug presentation felt influenced. While 87.5% appreciated the benefits of marketing strategies, about 70% would consider patients’ socioeconomic status before prescribing. Continuing medical education and stiff competition were reasons adduced for the marketing strategies. CONCLUSION: Pharmaceutical companies in Nigeria adopt varied strategies to influence doctors’ prescriptions. Often this aim is achieved. The practice is accepted by most who nevertheless will consider other factors when deciding on what to prescribe. [TAF Prev Med Bull 2010; 9(1.000: 1-6

    The authors present the results of an Nd isotope study on the major rock units of the Pan-African (1,100-500 Myr BP) terrane. Charnockites from Jabel Uweinat, a basement inlier at the junction of Egypt, Libya and the Sudan, yield middle Archaean model Nd ages, whilst model ages of < 1,200 Myr have been obtained in a belt from the Eastern Desert of Egypt to north-west Kenya. Overall, the Pan-African rocks from north-east and east Africa and those from the Damara of Namibia exhibit a wide range of epsilonsub(Nd)(T) from +7.5 to -18.0 which reflects regional changes in tectonic style and is not readily reconciled with simple models for the evolution of average continental crust.

    North American research has consistently reported higher social anxiety among people of Asian heritage compared to people of Western heritage. The present study used a cross-national sample of 692 university students to explore explanatory hypotheses using planned contrasts of group differences in social anxiety and related variables. The East Asian socialization hypothesis proposed social anxiety would show a linear relation corresponding to the degree of exposure to East Asian cultural norms. This hypothesis was not supported. The cultural discrepancy hypothesis examined whether bicultural East Asian participants (residing in Canada) would endorse higher social anxiety in comparison to unicultural participants (Western-heritage Canadians and native Koreans and Chinese). Compared to unicultural participants, bicultural East Asian participants reported higher social anxiety and depression, a relation that was partially mediated by bicultural participants' reports of lower self-efficacy about initiating social relationships and lower perceived social status. Overall, the results suggest higher reports of social anxiety among bicultural East Asians may be conceptualized within the context of cultural discrepancy with the mainstream culture.

    Background Medical ethics is not given due priority in obstetric care in many developing countries, and the extent to which patients value compliance with ethical precepts is largely unexplored. Objective To describe the expectations and experiences of obstetric patients in South East Nigeria with respect to how medical ethics principles were adhered to during their care. Methods This was a cross-sectional, questionnaire-based study involving parturient women followed in three tertiary hospitals in South East Nigeria. Results A total of 1,112 women were studied. The mean age of respondents was 29.7 ± 4.1 years. Approximately 98% had at least secondary education. Ninety-six percent considered ethical aspects of care as important. On the average, over 75% of patients expected their doctors to comply with the different principles of medical ethics and specifically, more than 76% of respondents expected their doctors to comply with ethical principles related to information and consent during their antenatal and delivery care. There was a statistically significant difference between the proportions of women who expected compliance of doctors with ethical principles and those who did not (P residence in urban areas (OR 2.41, P principles by doctors were encouraging, experiences fell short of expectations, as the level of expectation of patients was significantly higher than the level of observed compliance for all the principles of medical ethics. Conclusion The level of practice of medical ethics principles by doctors during obstetric care in South East Nigeria was encouraging but still fell short of the expectations of patients. It is recommended that curriculum-based training of doctors and medical students should be implemented, and hospital policy makers should do more to promote ethical aspects of care, by providing official written guidelines for adherence to medical ethical principles during obstetric care.

    Piasecki, Stefan

    2004-11-01

    Full Text Available Three sections in Hochstetter Forland, North-East Greenland, referred to the Jurassic Payer Dal and Bernbjerg Formations, have been analysed for dinoflagellate cysts. The dinoflagellate cysts,new finds of ammonites and previously recorded marine faunas form the basis for improved dating of the succession. The basal strata of the Payer Dal Formation at Kulhus is here dated as Late Callovian, Peltoceras athleta Chronozone, based on the presence of relatively abundant Limbicysta bjaerkei, Mendicodinium groenlandicum, Rhychoniopsis cladophora and Tubotuberella dangeardii in an otherwise poor Upper Callovian dinoflagellate assemblage. Ammoniteshave not been recorded from these strata. The upper Payer Dal Formation at Agnetesøelven is dated as Late Oxfordian, Amoeboceras glosense – Amoeboceras serratum Chronozones, based onthe presence of Sciniodinium crystallinum, together with Cribroperidinium granuligera and Stephanelytron sp. The age is in accordance with ammonites present in the uppermost part ofthe formation at Søndre Muslingebjerg. New ammonites in the Bernbjerg Formation at Agnetesøelven together with dinoflagellate cysts indicate an earliest Kimmeridgian age, Raseniacymodoce and Aulacostephanoides mutabilis Chronozones.The Upper Callovian dinoflagellate cysts from Hochstetter Forland belong to a local brackish to marginal marine assemblage, which only allows a fairly broad correlation to coeval assemblagesin central East Greenland. In contrast, the Oxfordian and Kimmeridgian assemblages are fully marine and can be correlated from Milne Land in central East Greenland via Hochstetter Forland to Peary Land in eastern North Greenland.

  17. Rhachotropis (Eusiroidea, Amphipoda from the North East Atlantic

    Directory of Open Access Journals (Sweden)

    Anne-Nina Lörz

    2018-01-01

    Full Text Available The genus Rhachotropis has the widest geographic and bathymetric distribution of all amphipod genera worldwide. Molecular and morphological investigations of specimens sampled around Iceland and off the Norwegian coast allow the first insights into the relationships of North East Atlantic Rhachotropis. The 31 cytochrome oxidase subunit I (COI sequences generated for this study were assigned 13 Barcode Index Numbers (BINs in the Barcode of Life database (BOLD, of which 12 are new to the database. Molecular analyses of COI and 16S sequences could not confirm a theory that depth has a greater influence on the phylogeny of Rhachotropis than geographic distance. Although the North East Atlantic is a well-studied area, our molecular investigations revealed the genus Rhachotropis may contain cryptic species, which indicates a higher biodiversity than currently known. For example, the specimens which key to Rhachotropis helleri is a complex of three COI clades, two of which cannot be identified with morphological traits. One specimen of each of the clades in the cladogram was documented by high definition photographs. A special focus was on the visual morphology of the eyes, as this character shows interspecific differences within the genus Rhachotropis in response to fixation in ethanol. Detailed morphological investigation showed that some clades thought to be indistinguishable can be separated by minute but consistent morphological characters. Datamining Genbank to examine all registered COI-sequences of R. aculeata, the only previously known Rhachotropis BIN in the North Atlantic and sub-Arctic, showed R. aculeata to be subdivided by an Arctic and a North Atlantic population.

    Suicide is among the leading causes of death in North America for various age groups. Given the far-reaching impacts of suicide on families and societies, there is growing research on this phenomenon; yet, most focus primarily on mainstream populations (i.e. Caucasian, native-born Americans or Canadians) and/or aggregated population data. As a result cultural considerations within multi-cultural milieus and increasing globalization can be overlooked. This scoping review reports findings drawn from 11 studies examining suicide among East Asian (EA) population in North America. A web-based literature search was performed to identify original research articles published from January 2002 to December 2011, addressing suicide among EAs living in North America, specifically in the USA and Canada. Four prominent thematic findings were identified in the literature related to: (1) rates of suicidal ideation and behavior among EAs in North America; (2) acculturation; (3) family support and conflict; and (4) other cultural and ethnic considerations. Further research, particularly qualitative and/or mixed methods, is needed to provide a more complete understanding of suicide among this under-studied population. This article concludes with a list of recommendations for future research based on the review.

  1. Pitmatic: the talk of the north east coalfields

    Bill Griffiths (comp.)

    2007-07-15

    The dictionary of Pitmatic, the oddly-named argot of north-east Englands miners for more than 150 years, has been compiled through detailed research in archives and interviews with the last generation to talk of kips, corf-batters and arse-loops. First recorded in Victorian newspapers, the language was part of the intense camaraderie of underground working which excluded even friendly outsiders such as the parliamentary commissioners pressing for better conditions in the pits in 1842. 'The barriers to our intercourse were formidable,' they wrote in their report on encountering the Pitmatic dialect. 'Numerous mining technicalities, northern provincialisms, peculiar intonation and accents and rapid and indistinct utterance rendered it essential for us to devote time to the study of these peculiarities ere we could translate and write the evidence.' The book includes pit recollections and analysis of the origins of the dialect's words. It reveals a rich combination of borrowings from Old Norse, Dutch and a score of other languages, with inventive usages dreamed up by the miners themselves. Part-financed by the Heritage Lottery Fund, in a three-stage dialect study of the north-east called Wor Language, the dictionary reveals the deeply practical nature of Pitmatic. The dialect was originally called Pitmatical, and its curious name was a parallel to mathematics, intended to stress the skill, precision and craft of the colliers' work.

    Abnormalities in serum lipid and lipoprotein levels are recognized major modifiable cardiovascular disease and essential hypertension risk factors. The objective of this study was to examine the serum lipid patterns of newly diagnosed hypertensive patients attending a tertiary healthcare centre in South East Nigeria. Methods. Two hundred and fifty newly diagnosed adult hypertensive patients and an equal number of age- and sex-matched controls without hypertension were consecutively recruited from the Medical and General Outpatient Clinics of Nnamdi Azikiwe University Teaching Hospital, Nnewi. Result. 126 males and 124 females were in each of the two groups. Mean age was comparable in both groups. Hypertensives had significantly higher mean systolic blood pressure, diastolic blood pressure, body mass index, waist circumference, waist-hip ratio, and fasting blood sugar than the controls. The mean TC, TG, and LDL-C were significantly higher among the hypertensives. The mean HDL-C was comparable; P = 0.8. Among the hypertensive subjects, there was statistically significant positive correlation between BMI and TC; LDL-C and TG; WC and TG; FBS and TC; LDL-C and TG. HDL-C showed a statistically significant inverse correlation with WHR in hypertensives. Conclusion. This study showed that lipid abnormalities are highly prevalent among newly diagnosed hypertensives in South-East Nigeria.

    Full Text Available An assessment of palm kernel processing and storage in South-Eastern Nigeria was carried out by investigative survey approach. The survey basically ascertained the extent of mechanization applicable in the area to enable the palm kernel processors and agricultural policy makers, device the modalities for improving palm kernel processing in the area. According to the results obtained from the study, in Abia state, 85% of the respondents use mechanical method while 15% use manual method in cracking their kernels. In Imo state, 83% of the processors use mechanical method while 17% use manual method. In Enugu and Ebonyi state, 70% and 50% of the processors respectively use mechanical method. It is only in Anambra state that greater number of the processors (50% use manual method while 45% use mechanical means. It is observable from the results that palm kernel oil extraction has not received much attention in mechanization. The ANOVA of the palm kernel oil extraction technique in South- East Nigeria showed significant difference in both the study area and oil extraction techniques at 5% level of probability. Results further revealed that in Abia State, 70% of the processors use complete fractional process in refining the palm kernel oil; 25% and 5% respectively use incomplete fractional process and zero refining process. In Anambra, 60% of the processors use complete fractional process and 40% use incomplete fractional process. Zero refining method is not applicable in Anambra state. In Enugu sate, 53% use complete fractional process while 25% and 22% respectively use zero refining and incomplete fractional process in refining the palm kernel oil. Imo state, mostly use complete fractional process (85% in refining palm kernel oil. About 10% use zero refining method while 5% of the processors use incomplete fractional process. Plastic containers and metal drums are dominantly used in most areas in south-east Nigeria for the storage of palm kernel oil.

    Cassava mosaic disease (CMD) caused by African cassava mosaic virus (ACMV) and East African cassava mosaic Cameroon virus (EACMCV) is the major constraint to cassava production in Nigeria. Sequences of the DNA-A component of ACMV and EACMCV isolates from leguminous plant species (Senna occidentalis, Leucana leucocephala and Glycine max), castor oil plant (Ricinus communis), a weed host (Combretum confertum) and a wild species of cassava (Manihot glaziovii) were determined. All ACMV isolates from these hosts showed 96-98% nucleotide sequence identity with cassava isolates from West Africa. EACMCV was found only in four hosts (S. occidentalis, L. leucocephala, C. confertum, M. glaziovii), and sequences of these isolates showed 96-99% identity with cassava isolates from West Africa. These results provide definitive evidence for the natural occurrence of ACMV and EACMCV in plant species besides cassava.

The aim was to study the reasons patients seek TBS treatment. Methods: This was a descriptive hospital-based study of 120 patients who were treated by TBS. The sociodemographic profile of the patients, details of injuries sustained, reasons for TBS patronage, duration of TBS treatment, the number of TBS visited, the reason for abandoning TBS treatment, patients’ belief about the TBS practice, and outcome of their treatment were studied. Results: Out of 418 patients who presented with musculoskeletal injuries, 120 patients who had been treated by TBS before presentation met the inclusion criteria. The mean age of the patients was 37.4±10.5 years. Advice of relatives and friends, as seen in 35 (29.2% patients, was the most common reason for TBS patronage.

    In Nigeria, communal conflicts arise due to misunderstanding from ownership of land for farming, oil deposits, solid minerals or water for fishing activities. It may also arise in defence of community pride and properties or even in defence of the people involved in the conflict. The General Health Questionnaire (GHQ-12), The Short Screening Scale for Post traumatic stress disorder, The Generalized Anxiety Disorder Scale (GAD-7) and the Beck Depression Inventory (BDI-2) were used to assess psychosocial impacts of communal conflicts among 560 secondary school youths from two communities in south east Nigeria. Result revealed various forms of psychosocial impacts of communal conflicts among the youths.

    The objective of this study is to examine the factors that influence the occurrence of childhood anaemia in North-East India by exploring dataset of the Reproductive and Child Health-II Survey (RCH-II). The study population consisted of 10,137 children in the age-group of 0-6 year(s) from North-East India to explore the predictors of childhood anaemia by means of different background characteristics, such as place of residence, religion, household standard of living, literacy of mother, total children ever born to a mother, age of mother at marriage. Prevalence of anaemia among children was taken as a polytomous variable. The predicted probabilities of anaemia were established via multinomial logistic regression model. These probabilities provided the degree of assessment of the contribution of predictors in the prevalence of childhood anaemia. The mean haemoglobin concentration in children aged 0-6 year(s) was found to be 11.85 g/dL, with a standard deviation of 5.61 g/dL. The multiple logistic regression analysis showed that rural children were at greater risk of severe (OR = 2.035; p = 0.003) and moderate (OR = 1.23; p = 0.003) anaemia. All types of anaemia (severe, moderate, and mild) were more prevalent among Hindu children (OR = 2.971; p = 0.000), (OR = 1.195; p = 0.010), and (OR = 1.201; p = 0.011) than among children of other religions whereas moderate (OR = 1.406; p = 0.001) and mild (OR = 1.857; p=0.000) anaemia were more prevalent among Muslim children. The fecundity of the mother was found to have significant effect on anaemia. Women with multiple children were prone to greater risk of anaemia. The multiple logistic regression analysis also confirmed that children of literate mothers were comparatively at lesser risk of severe anaemia. Mother's age at marriage had a significant effect on anaemia of their children as well.

Objective: The purpose of this study was to describe the presentation and treatment of gynecological cancers and identify barriers to successful gynecological cancer treatment in a tertiary hospital in South East Nigeria. Methods: This study was a retrospective longitudinal analysis of the presentation and treatment of histologically diagnosed primary gynecological cancers from 2000 to 2010. Analysis was by descriptive and inferential statistics at the 95% level of confidence using Statistical Package for the Social Sciences version 17 software. Results: Records of 200 gynecological cancers managed during the study period were analyzed. Over 94% of cervical cancers presented in advanced stages of the disease and received palliative/symptomatic treatment. Only 1.9% of cervical cancer patients had radical surgical intervention, and postoperative mortality from these radical surgeries was 100%. Approximately 76% of patients with ovarian cancer had debulking surgery as the mainstay of treatment followed by adjuvant chemotherapy. Postoperative mortality from ovarian cancer surgery was 63%. Cutting edge cytotoxic drugs were not used as chemotherapy for ovarian and chorionic cancers. Compliance with chemotherapy was poor, with over 70% of ovarian cancer patients failing to complete the

    Literature in cultural psychology suggests that compared with North Americans, East Asians prefer context-rich cultural products (e.g., paintings and photographs). The present article further examines the preferred amount of information in cultural products produced by East Asians and North Americans (Study 1: Society for Personality and Social Psychology conference posters; Study 2: government and university portal pages). The authors found that East Asians produced more information-rich products than did North Americans. Study 3 further examined people's information search speed when identifying target objects on mock webpages containing large amounts of information. The results indicated that East Asians were faster than North Americans in dealing with information on mock webpages with large amounts of information. Finally, the authors found that there were cultural differences as well as similarities in functional and aesthetic preferences regarding styles of information presentation. The interplay between cultural products and skills for accommodating to the cultural products is discussed.

  10. Investigating the potential for "water piracy" in North East Greenland

    2013-04-01

    The incorporation of subglacial processes in ice flow models remains a challenge while at the same time observational evidence increasingly underscores the important role liquid water plays in ice flow dynamics. One of the many problems ice flow models face (that also includes scarcity of data at the bed and the deformational properties of water-saturated sediments) is the different time-scales on which the processes operate. For example, observations indicate that subglacial water may be re-routed to a neighbouring ice stream in response to changes in surface elevation. This implies that ice flow models have to allow for changes in ice flow mode where, depending on the basal properties, the flow may be dominated by deformation or basal sliding. The re-routing of water between neighbouring ice streams is often termed "water piracy" and in this study we demonstrate that the potential for water piracy exists even in regions with very small surface elevation changes. We use a simple, vertically integrated, 2D-plane ice flow model based on the shallow ice flow approximation to model the large-scale changes in surface elevation of North East Greenland in response to gravity and mass balance. Considering time-scales of 100-500 years the model predicts changes in elevation of less than a metre per year which is in agreement with data from remote sensing. We then calculate the corresponding changes in hydrological pressure potential and use evidence from radio-echo sounding data to identify areas with basal melting and thus potential liquid water production. The corresponding change in hydrological pressure potential in response to the surface elevation changes is sufficient to divert the subglacial water to different pathways. This change in subglacial water pathways could be sufficient to change the ice flow mode from deformation to sliding and might initiate speed-up and/or slow-down of the ice streams at the margins of the basin.

  11. Local seismic monitoring east and north of Toronto - Volume 1

    1996-08-01

    Monitoring of small magnitude ('micro') earthquakes in a dense local network is one of the techniques used to delineate currently active faults and seismic sources. The conventional wisdom is that smaller, but more frequent, seismic events normally occur on active fault planes and a log linear empirical relation between frequency and magnitude can be used to estimate the magnitude and recurrence (frequency) of the larger events. A program of site-specific seismic monitoring has been supported by the AECB since 1991, to investigate the feasibility of microearthquake detection in suburban areas of east Toronto in order to assess the rate activity of local events in the vicinity of the nuclear power plants at Pickering and Darlington. For deployment of the seismic stations at the most favorable locations an extensive background noise survey was carried out. This survey involved measuring and comparing the amplitude response of the ambient vibration caused by natural phenomena (e.g. wind blow, water flow, wave action) or human activities such as farming, mining and industrial work at 25 test sites. Subsequently, a five-station seismic network, with a 30 km aperture, was selected between the Pickering and Darlington nuclear power plants on Lake Ontario, to the south, and Lake Scugog to the north. The detection threshold obtained for two of the stations allows recording of local events M L =0-2, a magnitude range which is usually not detected by regional seismic networks. An analysis of several thousand triggered signals resulted in the identification of about 120 local events, which can not be assigned to any source other than the natural release of crustal stresses. The recurrence frequency of these microearthquakes shows a linear relationship which matches that of larger events in the last two centuries in this region. The preliminary results indicate that the stress is currently accumulating and is being released within clusters of small earthquakes

  12. Genetic assessment of ornamental fish species from North East India.

    Ornamental fishes are traded with multiple names from various parts around the world, including North East India. Most are collected from the wild, due to lack of species-specific culture or breeding, and therefore, such unmanaged collection of the wild and endemic species could lead to severe threats to biodiversity. Despite many regulatory policies, trade of threatened species, including the IUCN listed species have been largely uncontrolled, due to species identification problems arising from the utilization of multiple trade names. So, the development of species-specific DNA marker is indispensable where DNA Barcoding is proved to be helpful in species identification. Here, we investigated, through DNA Barcoding and morphological assessment, the identification of 128 ornamental fish specimens exported from NE India from different exporters. The generated sequences were subjected to similarity match in BOLD-IDS as well as BLASTN, and analysed using MEGA5.2 for species identification through Neighbour-Joining (NJ) clustering, and K2P distance based approach. The analysis revealed straightforward identification of 84 specimens into 35 species, while 44 specimens were difficult to distinguish based on CO1 barcode alone. However, these cases were resolved through morphology, NJ and distanced based method and found to be belonging to 16 species. Among the 51 identified species, 14 species represented multiple trade names; 17 species belonged to threatened category. Species-level identification through DNA Barcoding along with traditional morphotaxonomy reflects its efficacy in regulating ornamental fish trade and therefore, appeals for their conservation in nature. The use of trade names rather than the zoological name created the passage for trafficking of the threatened species and demands immediate attention for sustaining wildlife conservation.

    Phylogenetic and statistical analyses of DNA sequences of two genes, cytochrome oxidase subunit 1 (cox 1) of the mitochondrial DNA and 18S subunit of the nuclear ribosomal RNA (18S rRNA), was used to characterize Neoechinorhynchus species from fishes collected in different localities of North-East Asia. It has been found that four species can be clearly recognized using molecular markers-Neoechinorhynchus tumidus, Neoechinorhynchus beringianus, Neoechinorhynchus simansularis and Neoechinorhynchus salmonis. 18S sequences ascribed to Neoechinorhynchus crassus specimens from North-East Asia were identical to those of N. tumidus, but differed substantially from North American N. crassus. We renamed North-East Asian N. crassus specimens to N. sp., although the possibility that they represent a subspecies of N. tumidus cannot be excluded, taking into account a relatively small distance between cox 1 sequences of North-East Asian specimens of N. crassus and N. tumidus. Maximum likelihood, maximum parsimony and Bayesian inference analyses were performed for phylogeny reconstruction. All the phylogenetic trees showed that North-East Asian species of Neoechinorhynchus analyzed in this study represent independent clades, with the only exception of N. tumidus and N. sp. for 18S data. Phylogenetic analysis has shown that the majority of species sampled (N. tumidus+N. sp., N. simansularis and N. beringianus) are probably very closely related, while N. salmonis occupies separate position in the trees, possibly indicating a North American origin of this species. © 2013.

    "This paper looks at the origins and development of dry season labour migration from Sokoto in north-western Nigeria, a migratory system which is generally accepted as being a product of colonialism. The argument takes the opening years of colonial rule in Sokoto and tries to uncover the nature and type of migration which obtained at this time. It is suggested that early migration was influenced by the economy of the central Sudan of the late nineteenth century, and there was an overlap, rather than a sharp break, between pre-colonial and colonial economies." The changes that occurred in the 1930s are also analyzed. (summary in FRE) excerpt

    Knowledge, perception, and acceptance of plastic surgery among any population are influenced by channel of presentation. A good understanding of the public awareness will define the way plastic surgery services will be provided. To assess the knowledge, awareness of availability, and acceptance of plastic surgery practice in Enugu, South East Nigeria. A questionnaire-based prospective study. The electronic media is the most common medium of awareness. Less than half the sample knew about the existence of plastic surgeons in Enugu even though a large proportion was aware of the existence of plastic surgery as a specialty. The concentration of plastic surgeons in a center is directly related to awareness of plastic surgery services in that facility. The most common esthetic procedure done by a plastic surgeon in Enugu is tattoo removal and scar refashioning. Orthopedic surgeons are thought to be key players in the management of burn patients as much as the plastic surgeons due to the "SIGNPOST EFFECT." The level of awareness is high in the sampled population with associated increase in acceptance of its practice and willing utilization. All public hospitals should be encouraged to employ the services of plastic surgeons. Appropriate branding of specialized hospitals where plastic surgery service is available will advance the practice significantly.

    Full Text Available Abstract Background Parents and Health Care Workers have traditionally attributed a variety of symptoms to teething in young children. Some of these symptoms may however connote underlying serious medical condition in a child. There is little evidence to support these beliefs despite their implications on management of a symptomatic teething child. This study therefore seeks determine the beliefs and problems mothers associate with teething in Enugu, South-east Nigeria. Findings A cross-sectional survey involving sixty mothers presenting at a Children's clinic in Enugu metropolis using questionnaire. More than 90% of the respondents thought that babies can experience medical problems as a result of teething. The commonest medical problems perceived to be associated with teething were fever (71.7%, loose stools (58.3% and vomiting (35%. Conclusion Mothers still associate a variety of symptoms of childhood illnesses to teething and this association is not evidence based and could lead to delayed interventions, increased morbidity and mortality of children. It is important therefore that mothers and health workers caring for young children are educated on the need to seek prompt medical attentions in a symptomatic child.

    Full Text Available Depletion of cellular antioxidants can result from free radical formation due to normal endogenous reactions and the ingestion of exogenous substances and environmental factors. The levels of reactive oxygen species-(ROS- scavenging enzymes such as SOD and glutathione peroxidase have been shown to be significantly altered in malignant cells and in primary cancer tissues. The aim of this study was to determine the antioxidant status of patients with prostate disorders in South-East Nigeria to ascertain the possible role of depletion of antioxidants in prostatic degeneration. 104 subjects made up of 40 PCa patients, 32 with BPH, and 32 controls participated in this study. The levels of superoxide dismutase, glutathione peroxidase, vitamin C, and vitamin E were estimated using standard procedures. The results show that both the BPH and PCa patients had a significant decrease (P<0.05 in GPX, SOD, vitamin C, and vitamin E levels compared to the control subjects. However, there was also a significant decrease (P<0.05 in SOD and vitamin C levels in PCa patients when compared with the BPH group. This indicates that patients with BPH and prostate cancer have decreased antioxidant status and may benefit from micronutrient supplementation.

    Entrenching an effective family planning program has being a major challenge in Sub Saharan Africa. Determining the knowledge, attitude and practice of family planning among the women is very necessary in order to achieve success. The aim of this study iS to determine the knowledge, and practice of family planning among antenatal women in Nnewi, South East, Nigeria. A descriptive cross sectional study of 356 women attending antenatal clinic at Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria was carried out over a 5-month period. With the aid of pre-tested interviewer-administered semi structured questionnaires, information on biosocial characteristics, knowledge of, and practice of family planning as well as sources of information on family planning were obtained from the respondents. Data was analysis was done with Epi info statistical package, version 3.5.2 (2008) Three hundred and forty (95.5%) of the respondents knew about family planning out of which 260 (76.5%) had ever used a modern method. The male condom (256; 75.3%) and the natural method (Billings method) (150; 44.1%) were the commonly known methods. Also the commonest used methods were the male condom (144; 55.4%) and Billings method (96; 36.9%). Birth spacing (248; 72.9%) and limiting births (138, 40.6%) were mainly identified as the benefits of family planning and only 6 (1.7%) of the respondents identified family planning as being important in the reduction of maternal mortality. The major sources of information on family planning were health workers (224; 65.9%) and the radio (126; 37.1%). The knowledge and practice of family planning has improved among our women. However, the methods commonly used are those associated with high failure rates. Family panning program managers should recognize this limitation. There is need for public sensitization on the correct use of the Billings method and the male condom. Ultimately, our women should be encouraged to accept the more reliable methods

Knowledge of the epidemiology of preterm births is necessary for planning appropriate maternal and fetal care.Objective: The objective of this study was to determine the prevalence, pattern, and perinatal mortality associated with preterm births at the University of Nigeria Teaching Hospital, Enugu, South East Nigeria.Methods: This was a review of prospectively collected routine delivery data involving preterm deliveries that occurred between 1 January 2009 and 31 December 2013. Data analysis involved descriptive and inferential statistics at 95% level of confidence using SPSS version 17.0 for Windows.Results: There were 3,760 live births over the 5-year study period out of which 636 were preterm births, giving a prevalence rate of 16.9%. Spontaneous preterm births occurred in approximately 57% of preterm births while provider-initiated births occurred in 43%. The mean gestational age at preterm deliveries was 32.6±3.2 weeks while the mean birth weight was 2.0±0.8 kilograms. Approximately 89% of preterm births involved singleton pregnancies. Sixty-eight percent of preterm births were moderate to late preterm. The male:female ratio of preterm babies born during the period was 1.2:1. The adjusted

    Occupational exposure to petroleum products is known to be associated with a number of health risks as well as adverse effects on haematological indices. To evaluate the effect of exposure to petroleum products on haematological parameters in automobile mechanics in Nnewi, south-east Nigeria. Fifty (50) automobile technicians and 50 healthy controls participated in the study. Full blood count was performed for each participant using the automated Sysmex haemocytometer (Model PCE 210) while data analysis was done using the SPSS (statistical package for social sciences) version 16 computer soft ware (Chicago, IL, Inc.). Results were expressed as frequencies, means and standard deviations; comparison of haematological parameters was made between subjects and controls and at different durations of exposure using the students' t-test and analysis of variance (ANOVA), respectively. The level of statistical significance was p < 0.05 (at 95% CI). Ethical approval was obtained from the Institutional review board and all participants gave informed consent. There red blood cell count (RBC) and haematocrit were significantly lower while the platelet count was significantly higher in test subjects compared with controls (p values; 0.04, 0.03 and 0.01, respectively). Correspondingly, the mean cell volume (MCV) and mean cell haemoglobin (MCH) were significantly lower in test subjects compared with controls (p = 0.62 and 0.03, respectively). The red cell count, MCV and platelet count significantly decreased with increasing duration of work exposure (p = 0.001, respectively). Occupational exposure to petroleum products adversely affects blood counts, with a significant decrease in RBC, MCV and platelet count as duration of exposure increases.

    Cardiovascular disease (CVD) is one of the top killer diseases in the world sparing neither developed or developing countries. The study was carried out to determine the pattern of cardiovascular admissions at Nnamdi Azikiwe University Teaching Hospital Nnewi South East Nigeria. The study was a retrospective study covering the period January 2007 to December 2009. SPSS version 13 software was used to analyze data. 537 (15%) patients were admitted into the study out of 3546 patients {females 1756 and 1790} admitted into medical wards. 322 (60%) of study population were males and 215 (40%) females. 359(67.5%) were discharged, 170 (32%) died and 8 (0.5%) were discharged against medical advice. The majority of the deaths 105(61.8%), were in patients with CVA. Most of the deaths (111 or 65.3%) occurred within the first seven days of admission. The mean age of the population was 60.7 years ±15.9 with a range of 18 to 110 years. The length of stay in hospital ranged between 1 and 140 days with a mean of 13.5 ± 13.9 days and a median of 10 days. 33 of the subjects were single, 406 were married, 94 were widowed (11 males and 83 females) and 4 were divorced. 46.7% (251) were admitted for CVA and 30.9% (166) for heart failure. Cardiomyopathy/valvular heart diseases (clinical diagnosis due to absence of echocardiography) constituted 3.9%, hypertension 20.5% and pre-existing hypertension with uremia 1.9%. The study has shown that cardiovascular disease contributed significantly to medical admissions the elderly accounting for a significant proportion. There is thus the need for intensification of primary preventive strategies for cardiovascular diseases.

    Primary health care (PHC) is a vital in any community. Any health centre with a well implemented PHC program can stand the test of time in curbing under five mortality and morbidity. This study was therefore aimed at assessing the activities in a health centre located in a rural area in Enugu state and to determine the pattern and presentation of various diseases in the health centre. This is retrospective study undertaken in a primary health care centre in Abakpa Nike in Enugu east LGA of Enugu State of Nigeria from December 2011 to December 31(st) 2013. Data retrieved were collected with the aid of a structured study proforma and analyzed using SPSS Version 18. Total number of children that attended immunization program in the health centre over 20 months period was 25,438 (12,348 males and 13090 females), however only 17745 children (7998 males and 9747 females) were actually registered in the hospital records. None of the children was immunized for DPT2 and OPV(0) and HBV(1) in the course of this study. The dropout rate using DPT1, 2 and 3 (DPT1-DPT2/DPT3) was very high (494%). The mean immunization coverage rate was 8.3%. Family planning activities, integrated management of childhood illnesses program were also carried out in the health centre but at very low level. The major fulcrum of events in the health centre which include immunization coverage, IMCI, and management of common illnesses were simply non operational. However the health centre had a well knitted referral system.

    In this study, which was part of a larger project I undertook in North-central Nigeria, I explored the differences in the sexual health seeking behavior of Tarok women and men and how these differences affect the spread of HIV. With the help of three research assistants, I conducted 16 in-depth interviews and 24 focus group discussions in four Tarok communities in North-central Nigeria. I found certain negative effects of gender inequality on women's sexual health seeking behavior in particular, a situation that has adverse implications for HIV acquisition and transmission. I therefore concluded that addressing the challenges of gender inequality is imperative for a sustained fight against HIV and AIDS in Nigeria.

    Childhood mortality rate is high in Nigeria. There is dearth of information on the comparison of childhood mortality probability and its causal factors in the Northern and Southern Nigeria. This study was designed to fill these gaps. Nigeria Demographic and Health Survey, 2008 data was used. The first part of this study focused on women aged 15-49 who ever given birth to a child (n = 23,404), irrespective of the survival status of the child and the second part utilized all women aged 15-49 (N = 33,385). The outcome variable was experienced childhood mortality. Data was analyzed using Chi-square, logistic regression and Brass logit model. Results showed that similar patterns of children's death were observed in the two regions, but variation existed. Childhood mortality experienced was more pronounced in the North than the South, even when the potential confounding variables were used as control. Levels of education and wealth index showed an inverse relationship with childhood death in the regions (p childhood mortality experienced between the poorest and richest was wider in the North than the South. There was no significant difference in the risk of childhood mortality experienced by women in the urban and rural areas in the North (p > 0.05), but the difference was significant in the South (p childhood mortality experience in the North than in the South. Across all childhood ages, the smoothed childhood mortality probabilities were consistently higher in the North than the South. Childhood mortality is higher in the Northern than Southern Nigeria. Improving women's education, particularly in the North will alleviate childhood mortality in Nigeria.

    Full Text Available In this paper we propose to highlight the tourism evolution and its intensity in the North-East region of Romania, compared to two regions with similar touristic potential from the Eastern European Union: Subcarpathia from Poland and Central Slovakia. We analysed if the EU attachment of Romania, Poland, and Slovakia had some effects on tourism development in the three regions mentioned. Issues arising from the analysis of the current situation of tourism will allow us to draw some sustainable development directions of tourism in the North-East region based on conserving and capitalizing the uniqueness of the area. We will consider the experience of the other two regions, trying to adapt them to the situation of the North-East region. Based on the analysis we have made, we consider that other countries can inspire us by authorities’ initiatives in supporting tourism, good human resources training, entrepreneurship stimulation, and assistance in accessing financial resources, including EU ones.

    The yellow fever epidemic in Nigeria in 1969-70 emphasized the lack of data concerning the possible importance of Aedes aegypti and other Stegomyia mosquitos as vectors. An entomological survey was therefore undertaken in September 1973 in 6 areas in the north-west of Nigeria to determine the prevalence of Stegomyia populations in the villages. An examination of over 6 700 water pots showed that 11-53% contained A. aegypti larvae, and in some areas larvae of A. vittatus were found in up to 18% of pots. In villages in the relatively dry Sudan savanna neither leaf axils nor tree-holes were important Stegomyia larval habitats, but in the more southern Kontagora area of the wetter northern Guinea savanna, these habitats were probably important breeding sites. In the early evening the most abundant man-biting mosquito in the villages was A. aegypti. A. vittatus was also caught at bait in some villages. It was concluded that the only potential yellow fever vectors in the area were A. aegypti and A. vittatus. There were large populations of A. aegypti, closely associated with man, in all the areas surveyed, but they should not present a risk of yellow fever transmission unless the disease were to be introduced into the area by man, or unless virus reservoirs, such as monkeys, were also present. Although monkeys were common in the Kontagora area they were rare in the Sudan savanna.

    Full Text Available Household expenditure on health has increasingly remained a major source of health care financing in Nigeria despite the introduction of several social health scheme policies provided by the government for meeting the health care costs of patients. Recognizing these limitations, this study assessed the type of health care services people commonly use in various illnesses and the sociodemographic correlates of the preferred health care services by household heads in six rural communities of North Central Nigeria. A cross-sectional community-based descriptive study design was used to study 154 household heads in the settlements using a multistage sampling method. Multiple logistic regressions were performed to investigate independent predictors that had significant chi-square at P<0.05. The leading causes of illness experienced by respondents were medical conditions (42.0% and 41.7% of them sought treatment from patent medicine vendors. The dominant reasons for health-seeking preferences were financial access (53.7% and proximity (48.6%. Age had a higher impact (Beta = 0.892 on the health-seeking preferences of the respondents as compared to their occupation and religion (Beta = 0.368 and −0.746, resp.. Therefore, in order to meet the health care of patients, it is pertinent that the unmet needs of patients are properly addressed by appropriate agencies.

    Full Text Available Economic analysis of Upland and Swamp rice production in Ebonyi State, South east Nigeria was studied and analyzed in 2011 farming season. Purposive and multistage random sampling technique was used to select agricultural blocks, circles and rice farmers. The sample size was 240 rice farmers (120 Agricultural Development Programme (ADP Upland rice contact farmers and 120 Agricultural Development Programme (ADP Swamp contact rice farmers. Data for the analysis were collected from a structured questionnaire. The result indicates that mean ages of upland rice farmers was 37.3 years while swamp rice farmers had 39.2 years. The mean farming experience for both farmers were 8.5 years (upland rice farmers and 8.8 years (swamp rice farmers with farm sizes of 1.2 and 1.1 hectares for upland rice farmers and swamp rice farmers respectively. Upland rice farmers had an annual farm income of 189,410.00 NGN (1,222USD as against 201,166.00 NGN (1,297.85USD for Swamp rice farmers. The multiple regression (Cobb Douglas estimates of the determinants of output of upland rice showed that coefficients age, farming experience, farm size, variable inputs and farm income were positively signed at given levels of probability while capital inputs was negative. The Cobb Douglas regression estimates of the determinants of output of Swamp rice showed that the coefficients of education, labour cost, farm size, variable inputs and farm income were positively signed and significant at given levels of probability as well as capital inputs which was negative. The result indicates that net profit from Upland rice cultivation was 92,800.00 NGN (598.71USD with a Benefit Cost Ratio of N1.55 (1.56USD. The net profit from Swamp rice cultivation was 132,090.00 NGN (852.19USD and a Benefit Cost Ratio of 1.75 NGN (1.75USD. Access to credit to rice farmers, subsidy on farm inputs, dissemination of improved rice technologies by extension agents and formation of farmer groups were advocated

    2017-10-01

    We assess the ability of the DePreSys3 prediction system to predict the summer (JJAS) surface-air temperature over North East Asia. DePreSys3 is based on a high resolution ocean-atmosphere coupled climate prediction system ( 60 km in the atmosphere and 25 km in the ocean), which is full-field initialized from 1960 to 2014 (26 start-dates). We find skill in predicting surface-air temperature, relative to a long-term trend, for 1 and 2-5 year lead-times over North East Asia, the North Atlantic Ocean and Eastern Europe. DePreSys3 also reproduces the interdecadal evolution of surface-air temperature over the North Atlantic subpolar gyre and North East Asia for both lead times, along with the strong warming that occurred in the mid-1990s over both areas. Composite analysis reveals that the skill at capturing interdecadal changes in North East Asia is associated with the propagation of an atmospheric Rossby wave, which follows the subtropical jet and modulates surface-air temperature from Europe to Eastern Asia. We hypothesise that this `circumglobal teleconnection' pattern is excited over the Atlantic Ocean and is related to Atlantic multi-decadal variability and the associated changes in precipitation over the Sahel and the subtropical Atlantic Ocean. This mechanism is robust for the 2-5 year lead-time. For the 1 year lead-time the Pacific Ocean also plays an important role in leading to skill in predicting SAT over Northeast Asia. Increased temperatures and precipitation over the western Pacific Ocean was found to be associated with a Pacific-Japan like-pattern, which can affect East Asia's climate.

    The objective of this study was to determine the knowledge and attitudes of practicing Nigerian lawyers towards issues relating to reproductive health and reproductive rights, and their opinions about abortion law reform. It was a population- based study which consisted of interviews with practicing lawyers in north-east Nigeria. The results showed poor knowledge of issues related to reproductive health and reproductive rights among the lawyers. However, the majority (56.9%) disagreed that a woman can practice family planning without the consent of her husband. The prevalence of contraceptive use among the lawyers was low and attitude to abortion law not satisfactory. Only few lawyers (22.4%) supported safe abortion in cases of failed contraception. We conclude that reproductive health advocates must target legal professionals with a view to educating them on issues relating to sexual and reproductive health and rights. Lawyers in Nigeria should undergo capacity building in reproductive health laws and be encouraged to specialize in reproductive rights protection as obtainable in other developed countries.

  1. Politics, institutions and the decline of coal mining in North East England

    2003-04-01

    The decline of coal mining in North East England and the policy responses to this are reviewed using a tradition of political economy that also draws upon insights from sociology and political science. Coal mining and traditional industries such as steelmaking, shipbuilding and heavy engineering were always closely linked in the North East, and the decline of the latter in the interwar years had a devastating effect on the region's economy. The reasons for this decline and the failure to transfer resources into new sectors can be attributed to the decline of local sources of financing in favour of the City of London and the consequent erosion of direct ties between the local capitalist class and the economic fate of the North East. State funded attempts to regenerate industry, in the post-war period had limited success in generating employment but failed to establish networks of businesses capable of generating self-sustaining growth. The devolved but limited powers potentially available to a regional assembly for the North East may offer a way forward.

    This work aims at characterising the seamount physiography and biology in the OSPAR Convention limits (North-East Atlantic Ocean) and Mediterranean Sea. We first inferred potential abundance, location and morphological characteristics of seamounts, and secondly, summarized the existing biological, geological and oceanographic in-situ research, identifying examples of well-studied seamounts. Our study showed that the seamount population in the OSPAR area (North-East Atlantic) and in Mediterranean Sea is large with around 1061 and 202 seamount-like features, respectively. Similarly, seamounts occupy large areas of about 1 116 000 km2 in the OSPAR region and of about 184 000 km2 in the Mediterranean Sea, which is much larger than previously thought. The presence of seamounts in the North-East Atlantic has been known since the late 19th Century but overall knowledge regarding seamount ecology and geology is still relatively poor. Only 37 seamounts in the OSPAR area (3.5% of all seamounts in the region), 22 in the Mediterranean Sea (9.2% of all seamounts in the region) and 25 in the North-East Atlantic south of the OSPAR have in-situ information. Seamounts mapped in both areas are in general very heterogeneous, showing diverse geophysical characteristics. These differences will likely affect the biological diversity and production of resident and associated organisms.

    Full Text Available This work aims at characterising the seamount physiography and biology in the OSPAR Convention limits (north-east Atlantic Ocean and Mediterranean Sea. We first inferred potential abundance, location and morphological characteristics of seamounts, and secondly, summarized the existing biological, geological and oceanographic in situ research, identifying examples of well-studied seamounts. Our study showed that the seamount population in the OSPAR area (north-east Atlantic and in the Mediterranean Sea is large with around 557 and 101 seamount-like features, respectively. Similarly, seamounts occupy large areas of about 616 000 km2 in the OSPAR region and of about 89 500 km2 in the Mediterranean Sea. The presence of seamounts in the north-east Atlantic has been known since the late 19th century, but overall knowledge regarding seamount ecology and geology is still relatively poor. Only 37 seamounts in the OSPAR area (3.5% of all seamounts in the region, 22 in the Mediterranean Sea (9.2% of all seamounts in the region and 25 in the north-east Atlantic south of the OSPAR area have in situ information. Seamounts mapped in both areas are in general very heterogeneous, showing diverse geophysical characteristics. These differences will likely affect the biological diversity and production of resident and associated organisms.

    2017-12-01

    The path and speed of extratropical cyclones along the east coast of North America influence their societal impact. This work characterizes the climatological relationship between cyclone track path and speed, and blocking and the North Atlantic Oscillation (NAO). An analysis of Lagrangian cyclone track propagation speed and angle shows that the percentage of cyclones with blocks is larger for cyclones that propagate northward or southeastward, as is the size of the blocked region near the cyclone. Cyclone-centered composites show that propagation of cyclones relative to blocks is consistent with steering by the block: northward tracks more often have a block east/northeast of the cyclone; slow tracks tend to have blocks due north of the cyclone. Comparison with the NAO shows that to first-order blocking and the NAO steer cyclones in a similar manner. However, blocked cyclones are more likely to propagate northward, increasing the likelihood of cyclone related impacts.

    The MENA region is endowed with enormous resources of oil and gas, rendering it the world′s richest region in this regard. Endowment differs from one country to another with few countries are almost dry; however the economic benefits proliferated to almost every country in the region. In spite of some doubts being cast about the amount of proven oil reserves, these with improved technology and new discoveries are increasing year after another. With no long term feasible alternatives to oil for transport and the increasing trade in LNG, the region′s importance as a world′s leading supplier of fossil fuels will continue for decades to come. However, these favourable prospects hide many challenges facing the MENA region, among them is the difficulty in mobilizing investment funds for sustaining and increasing output to feed growing global demand. Growing local demand, due to the proliferation of subsides, is another worrying aspect that already caused few countries with modest resources to become oil importers instead of exporters, with larger exporters decreasing their surplus output. The region is also still mainly dependant on foreign technologies and skilled manpower. Regional cooperation in oil and gas networks and electricity interconnections is still modest. The region has a long history of conflict; correspondingly it is a major importer of armaments which is increasingly eating a lot of its surplus income. With the political and social changes presently taking place in many MENA countries, due to the Arab spring and continuation of local conflicts, the sustainability of supplies from the region are increasingly a source of worry to MENA exporters and its many importers. It is also causing increasing involvement of the super powers in regional affairs. - Highlights: • Global oil and gas reserves and prices. • Energy sustainability and the Middle East. • Energy economics and investments in the Middle East

    Full Text Available Nigeria remains one of only three polio-endemic countries in the world. In 2016, after an absence of 2 years, wild poliovirus serotype 1 was again detected in North-Eastern Nigeria. To better guide programmatic action, we assessed the immunity status of infants and children in Borno and Yobe states, and evaluated the impact of recently introduced inactivated poliovirus vaccine (IPV on antibody seroprevalence.We conducted a facility-based study of seroprevalence to poliovirus serotypes 1, 2 and 3 among health-seeking patients in two sites each of Borno and Yobe States. Enrolment was conducted amongst children 6-9 and 36-47 months of age attending the paediatrics outpatient department of the selected hospitals in the two states between 11 January and 5 February 2016. Detailed demographic and immunization history of the child was taken and an assessment of the child's health and nutritional state was conducted via physical examination. Blood was collected to test for levels of neutralizing antibody titres against the three poliovirus serotypes. The seroprevalence in the two age groups, potential determinants of seropositivity and the impact of one dose of IPV on humoral immunity were assessed. A total of 583 subjects were enrolled and provided sufficient quantities of serum for testing. Among 6-9-month-old infants, the seroprevalence was 81% (74-87%, 86% (79-91%, and 72% (65-79% in Borno State, and 75% (67-81%, 74% (66-81% and 69% (61-76% in Yobe States, for serotypes-1, 2 and 3, respectively. Among children aged 36-47 months, the seroprevalence was >90% in both states for all three serotypes, with the exception of type 3 seroprevalence in Borno [87% (80-91%]. Median reciprocal anti-polio neutralizing antibody titers were consistently >900 for serotypes 1 and 2 across age groups and states; with lower estimates for serotype 3, particularly in Borno. IPV received in routine immunization was found to be a significant determinant of seropositivity and

    Full Text Available Abstract Background Anopheles baimaii is a primary vector of human malaria in the forest settings of Southeast Asia including the north-eastern region of India. Here, the genetic population structure and the basic population genetic parameters of An. baimaii in north-east India were estimated using DNA sequences of the mitochondrial cytochrome oxidase sub unit II (COII gene. Methods Anopheles baimaii were collected from 26 geo-referenced locations across the seven north-east Indian states and the COII gene was sequenced from 176 individuals across these sites. Fifty-seven COII sequences of An. baimaii from six locations in Bangladesh, Myanmar and Thailand from a previous study were added to this dataset. Altogether, 233 sequences were grouped into eight population groups, to facilitate analyses of genetic diversity, population structure and population history. Results A star-shaped median joining haplotype network, unimodal mismatch distribution and significantly negative neutrality tests indicated population expansion in An. baimaii with the start of expansion estimated to be ~0.243 million years before present (MYBP in north-east India. The populations of An. baimaii from north-east India had the highest haplotype and nucleotide diversity with all other populations having a subset of this diversity, likely as the result of range expansion from north-east India. The north-east Indian populations were genetically distinct from those in Bangladesh, Myanmar and Thailand, indicating that mountains, such as the Arakan mountain range between north-east India and Myanmar, are a significant barrier to gene flow. Within north-east India, there was no genetic differentiation among populations with the exception of the Central 2 population in the Barail hills area that was significantly differentiated from other populations. Conclusions The high genetic distinctiveness of the Central 2 population in the Barail hills area of the north-east India should be

    This cross-sectional descriptive survey investigated determinants of malaria prevention and treatment seeking behaviours of pregnant undergraduates resident in university hostels, South-East Nigeria. Purposive sampling was used to enrol 121 accessible and consenting undergraduates with self-revealed and noticeable pregnancy residing in twenty-three female hostels of four university campuses in Enugu State, Nigeria. Structured interview guide developed based on reviewed literature and WHO-recommended malaria prevention and treatment measures was used to collect students' self-report data on malaria preventive health behaviours, sick role behaviours, and clinic use using mixed methods. The WHO-recommended malaria prevention measures were sparingly used. Some believed that pregnancy does not play any role in a woman's reaction to malaria infection. Only 41 (50.6%) visited a hospital for screening and treatment. Thirty-four (28.1%) used antimalaria medicine bought from chemist shop or over-the-counter medicines, while 33 (27.3%) used untreated net. The students were more likely to complete their antimalaria medicine when they were sick with malaria infection than for prevention ( p = 0.0186). Knowledge, academic schedule, cultural influence on perception and decision-making, and accessibility of health facility were key determinants of the women's preventive and treatment seeking behaviours. Health education on malaria prevention and dangers of drug abuse should form part of orientation lectures for all freshmen. University health centres should be upgraded to provide basic antenatal care services.

    Full Text Available Measurements of activity concentrations of natural radionuclides in and around Obajana cement factory, North Central Nigeria have been carried out in this study to determine the activity levels of natural radionuclides in different environmental matrices in order to assess the radiological health hazards associated with the use of these matrices by the local population. A low-background Pb-shielded gamma spectroscopic counting assembly utilizing NaI (Tl detector was employed for the measurements. The results show that sediment samples have the highest activity concentrations of all the radionuclides relative to soil, farmland soil, and rock samples. The radium equivalent activity and indoor gamma dose rates together with the corresponding annual effective indoor doses evaluated were found to be lower than their permissible limits. It suffices to say, that contrary to age-long fear of radiation risks to the population in the vicinity of the cement factory, no excessive radiological health hazards either indoors and/or outdoors is envisaged. Therefore, the environmental matrices around the factory could be used without any restrictions.

    Full Text Available Holistic view of household energy consumption based on greenhouse gas emissions in the North Central cities of Nigeria was examined in this study. Scenarios considered were based on income level of energy users (low and high and energy metering system (i.e. pre-paid and post-paid energy billing systems. Strong direct nexus was observed between energy use and emissions pattern. Energy utilization by post-paid category had higher weekly average value of 35.09 and 41.70 kWh as against 23.18 and 33.38 kWh for low and high income pre-paid consumers respectively. Energy use and greenhouse gas emissions from both classification followed similar trend. Data obtained and analysed in the study show that global warming and acidification potentials could be reduced by 33.94 and 19.95 % for low and high income category consumers when pre-paid meters are in place. Conclusively, energy system users with pre-paid metering system displayed reasonable level of management decisions that reduce energy wastage and consequently environmental negative impacts.

    Full Text Available The aim of this research was to examine the energy use pattern, energy use efficiency and energy productivity for vegetable production under Fadama or the seasonally flooded or floodable plains along major savanna rivers in north central Nigeria. To achieve these objectives, the data for the production of four major vegetables produced under Fadama (Onion, Tomato, Sweet and Hot Pepper were collected from 192 Fadama farmers. The results show that Tomato production was the most energy intensive among the four vegetables investigated. For all the vegetables, the usage of non-renewable energy inputs such as petrol and urea fertilizer was quite substantial as such, the efficiency of energy use and energy productivity were very low. The energy use efficiency were, 0.20, 0.10, 0.10 and 0.06, while the energy productivity were 0.25, 0.12, 0.13 and 0.07 for Onion, Tomato, Sweet and Hot Pepper respectively. However, to enhance the energy use efficiency and energy productivity of the system, the usage of renewable energy inputs especially organic manure should be promoted. In addition, energy efficient water pumps should be introduced into the Fadama communities.

    In recent years, mathematical modelling allied to computer simulation has emerged as en effective and invaluable design tool for industry and a discipline in its own right. This has been reflected in the popularity of the growing number of courses and conferences devoted to the area. The North East Polytechnics Mathematical Modelling and Computer Simulation Group has a balanced representation of academics and industrialists and, as a Group, has the objective of promoting a continuing partnership between the Polytechnics in the North East and local industry. Prior to the present conference the Group has organised eight conferences with a variety of themes related to mathematical modelling and computer simulation. The theme chosen for the Polymodel 9 Conference held in Newcastle upon Tyne in May 1986 was Industrial Vibration Modelling, which is particularly approp riate for 'Industry Year' and is an area which continues to present industry and academics with new and challenging problems.

    Despite the extent of their reserves, oil production in most countries of the Middle East and North Africa is not likely to increase significantly in the years ahead. Exports from the Middle East, 75% of which are to Asia, and those from North Africa, most of which are focused on Europe, should remain stable overall. The increase in gas production will contribute more to meeting fast-growing domestic demand than to boosting exports. Indeed, many Middle Eastern countries are paradoxically experiencing strains on domestic energy supplies due to energy demand stimulated by energy prices that are generally - and artificially - very low, and the adoption of economic development models based on energy-intensive industries.

    Full Text Available The deterioration of soil quality/health is the combined result of soil fertility, biological degradation (decline of organic matter, biomass C, decrease in activity and diversity of soil fauna, increase in erodibility, acidity, and salinity, and exposure of compact subsoil of poor physicochemical properties. Northeast India is characterized by high soil acidity/Al+3 toxicity, heavy soil, and carbon loss, severe water scarcity during most parts of year though it is known as high rainfall area. The extent of soil and nutrient transfer, causing environmental degradation in North eastern India, has been estimated to be about 601 million tones of soil, and 685.8, 99.8, 511.1, 22.6, 14.0, 57.1, and 43.0 thousand tones of N, P, K, Mn, Zn, Ca, and Mg, respectively. Excessive deforestation coupled with shifting cultivation practices have resulted in tremendous soil loss (200 t/ha/yr, poor soil physical health in this region. Studies on soil erodibility characteristics under various land use systems in Northeastern Hill (NEH Region depicted that shifting cultivation had the highest erosion ratio (12.46 and soil loss (30.2–170.2 t/ha/yr, followed by conventional agriculture system (10.42 and 5.10–68.20 t/ha/yr, resp.. The challenge before us is to maintain equilibrium between resources and their use to have a stable ecosystem. Agroforestry systems like agri-horti-silvi-pastoral system performed better over shifting cultivation in terms of improvement in soil organic carbon; SOC (44.8%, mean weight diameter; MWD (29.4%, dispersion ratio (52.9%, soil loss (99.3%, soil erosion ratio (45.9%, and in-situ soil moisture conservation (20.6% under the high rainfall, moderate to steep slopes, and shallow soil depth conditions. Multipurpose trees (MPTs also played an important role on soil rejuvenation. Michelia oblonga is reported to be a better choice as bioameliorant for these soils as continuous leaf litter and root exudates improved soil physical

    Aleutian mink disease is the most important disease in the mink-farming industry worldwide. So far, few large-scale molecular epidemiological studies of AMDV, based on the NS1 and VP2 genes, have been conducted in China. Here, eight new Chinese isolates of AMDV from three provinces in north-east China were analyzed to clarify the molecular epidemiology of AMDV. The seroprevalence of AMDV in north-east China was 41.8% according to counterimmuno-electrophoresis. Genetic variation analysis of the eight isolates showed significant non-synonymous substitutions in the NS1 and VP2 genes, especially in the NS1 gene. All eight isolates included the caspase-recognition sequence NS1:285 (DQTD↓S), but not the caspase recognition sequence NS1:227 (INTD↓S). The LN1 and LN2 strains had a new 10-amino-acid deletion in-between amino acids 28-37, while the JL3 strain had a one-amino-acid deletion at position 28 in the VP2 protein, compared with the AMDV-G strain. Phylogenetic analysis based on most of NS1 (1755 bp) and complete VP2 showed that the AMDV genotypes did not cluster according to their pathogenicity or geographic origin. Local and imported ADMV species are all prevalent in mink-farming populations in the north-east of China. This is the first study to report the molecular epidemiology of AMDV in north-east China based on most of NS1 and the complete VP2, and further provides information about polyG deletions and new variations in the amino acid sequences of NS1 and VP2 proteins. This report is a good foundation for further study of AMDV in China.

    The study aims to provide a systematical revision of the traditional use of wild and cultivated plants in north-eastern Bosnia and Herzegovina (Western Balkan Peninsula; Southeast Europe). Thereby, it will extend and complement a recent previous study carried out in middle, southern and western Bosnia and Herzegovina. Information was collected by performing so called open ethnobotanical interviews. The following data were recorded and systematically assembled in a database: name, age and occupation of the interviewed person; the geographic locality and date of the interview; the name of the used plant; plant parts used; prescription background and preparation procedure as well as indication. Plants mentioned to be used by the informants were collected during field trips done together with the informants and taxonomically determined. The corresponding material was finally deposited in the herbarium of the Department of Pharmacognosy of the University of Vienna for the purpose of documentation. In total, 45 places including villages and mountain areas were visited and 84 persons questioned. 254 wild and cultivated species and 1655 different preparations for the use in traditional human therapy were recorded. The most frequently mentioned indications were disorders of the gastrointestinal tract, respiratory system, urogenital tract, skin, blood system, cardiovascular system, nervous system as well as rheumatism. Infusions were the most frequently prepared formulation. Other applied preparations mentioned with decreasing frequency were decocts, sirups, tinctures, collars, direct application of plants without prior preparation, ointments, freshly pressed juices, oils, powders, fluid unctions, macerations and finally suppositories. Special preparations, typical only for the area of Bosnia and Herzegovina were "mehlems" and some kind of sirup called "đulbe šećer" (eng. đulbe sugar). While "mehlems" were already recognized and accordingly discussed for the central

    Full Text Available The article is devoted to an analysis of the main factors, determining German policy in the Middle East and North Africa (MENA. More active German military-technical engagement in the settlement of the crises in the region on the modern stage determines relevance of this article’s topic. Based on historical method, author considers the development of German foreign policy in the Arab world, examining the main aspects of the colonial policy of German empire on the threshold of the First and Second World Wars, as well as the prerequisites of the intensification of German-Arabic contacts in the period of Cold War. In accordance with the principals of system analysis Germany’s Middle East policy was investigated in complex, given geopolitical, economic and military aspects. Special emphasis is put on the problem of transformation of Middle East regional order as a factor of political instability. Notwithstanding the rea-sonableness of Germany’s standing for stable and predictable regional order, these goals were challenged owing to the fact that Germany benefits from the regional disorder in terms of increase of its influence. In reliance on the German goals in the Middle East and North Africa, mentioned in the Coalition Agreement of 2013, the author points out the priority of crisis management. At the same time the ethno-confessional conflict potential of the region meets the interests of German military-industrial complex. Increase of Germany’s export of weapons to the Arab states as well as neglecting the restrictions on export go to prove that Germany backs the armaments race in the Middle East. In this regard, German policy is characterized by “double standards” and inconsistency. These specifics can be explained by the ongoing process of Middle East policy shift and searching for new priorities on a long-term horizon. In the conclusion, the author analyzes the specifics and prospects of German policy in MENA region.

    The research project 'An Evaluation of Transformational Change in NHS North East' examines the progress and success of National Health Service (NHS) organisations in north east England in implementing and embedding the North East Transformation System (NETS), a region-wide programme to improve healthcare quality and safety, and to reduce waste, using a combination of Vision, Compact, and Lean-based Method. This paper concentrates on findings concerning the role of leadership in enabling tranformational change, based on semi-structured interviews with a mix of senior NHS managers and quality improvement staff in 14 study sites. Most interviewees felt that implementing the NETS requires committed, stable leadership, attention to team-building across disciplines and leadership development at many levels. We conclude that without senior leader commitment to continuous improvement over a long time scale and serious efforts to distribute leadership tasks to all levels, healthcare organisations are less likely to achieve positive changes in managerial-clinical relations, sustainable improvements to organisational culture and, ultimately, the region-wide step change in quality, safety and efficiency that the NETS was designed to deliver. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available The article poses the problem of connection between the spiritual culture of the peoples of the North Caucasus and the culture of the East. The authors show the historical predetermination of this process, their aim is to solve the problem of forming the North Caucasian literary tradition as a whole, to characterize some of its aspects, in particular, such as the originality of distribution of the Arabic language, the development of Arabic-language literature, its role and character in the process of strengthening the Middle East Caucasian, North Caucasian contacts, North Caucasian literature in Arabic (mainly, Persian, Turkic languages, the formation and development of its genre forms. The authors note that the driving forces of the Arab-Muslim culture - the Arabic language and Islam - have penetrated into Dagestan and the North Caucasus along with the Arab campaigns. The Arabic language and Islam became an integral part of the culture of many Dagestani and North Caucasian peoples. Islam was one of the main, but not the only factor that determined the prospects for cultural interaction. The ethnic and linguistic diversity of Dagestan and the North Caucasus facilitated the wide dissemination of the Arabic language as a communication mean accessible to a large part of the population, in particular, to the clergy. The process of intraregional interaction of literatures is gaining momentum. Therefore, this influence has gradually created the local original literature in the Arabic language in Dagestan, Chechnya, Ingushetia, and in part of Kabarda and Circassia. The authors of this article trace the ideological and aesthetic originality of this regional national literature.

    The North East Department is a resource-limited region of Haiti. Health care is provided by hospitals and community clinics, with no formal Emergency Medical System and undefined emergency services. As a paucity of information exists on available emergency services in the North East Department of Haiti, the objective of this study was to assess systematically the existing emergency care resources in the region. This cross-sectional observational study was carried out at all Ministry of Public Health and Population (MSPP)-affiliated hospitals in the North East Department and all clinics within the Fort Liberté district. A modified version of the World Health Organization (WHO) Tool for Situational Analysis to Assess Emergency and Essential Surgical Care and Generic Essential Emergency Equipment Lists were completed for each facility. Three MSPP hospitals and five clinics were assessed. Among hospitals, all had a designated emergency ward with 24 hour staffing by a medical doctor. All hospitals had electricity with backup generators and access to running water; however, none had potable water. All hospitals had x-ray and ultrasound capabilities. No computed tomography scanners existed in the region. Invasive airway equipment and associated medications were not present consistently in the hospitals' emergency care areas, but they were available in the operating rooms. Pulse oximetry was unavailable uniformly. One hospital had intermittently functioning defibrillation equipment, and two hospitals had epinephrine. Basic supplies for managing obstetrical and traumatic emergencies were available at all hospitals. Surgical services were accessible at two hospitals. No critical care services were available in the region. Clinics varied widely in terms of equipment availability. They uniformly had limited emergency medical equipment. The clinics also had inconsistent access to basic assessment tools (sphygmomanometers 20% and stethoscopes 60%). A protocol for transferring

    Full Text Available Soils of Russian European North were investigated in terms of stability and quality of organic matter as well as in terms of soils organic matter elemental composi­tion. Therefore, soil humic acids (HAs, extracted from soils of different natural zones of Russian North-East were studied to characterize the degree of soil organic matter stabilization along a zonal gradient. HAs were extracted from soil of different zonal environments of the Komi Republic: south, middle and north taiga as well as south tundra. Data on elemental composition of humic acids and fulvic acids (FAs extracted from different soil types were obtained to assess humus formation mechanisms in the soils of taiga and tundra of the European North-East of Russia. The specificity of HAs elemental composition are discussed in relation to environmental conditions. The higher moisture degree of taiga soils results in the higher H/C ratio in humic substances. This reflects the reduced microbiologic activity in Albeluvisols sods and subsequent conser­vation of carbohydrate and amino acid fragments in HAs. HAs of tundra soils, shows the H/C values decreasing within the depth of the soils, which reflects increasing of aromatic compounds in HA structure of mineral soil horizons. FAs were more oxidized and contains less carbon while compared with the HAs. Humic acids, extracted from soil of different polar and boreal environments differ in terms of elemental composition winch reflects the climatic and hydrological regimes of humification.

  3. A millennium of north-east Atlantic cod juvenile growth trajectories inferred from archaeological otoliths.

    Guðbjörg Ásta Ólafsdóttir

    Full Text Available Archaeological excavations of historical fishing sites across the North Atlantic have recovered high quantities of Atlantic cod (Gadus morhua bones. In the current study we use Atlantic cod otoliths from archaeological excavations of a historical fishing sites in north-west Iceland, dated to AD 970 -AD 1910 to examine historical growth trajectories of cod. No large scale growth variations or shifts in growth patterns were observed in the current chronologies, supporting the stability of historical Atlantic cod growth trajectories. The most significant variation in growth patterns was consistent with those that have been observed in recent times, for example, reduced early juvenile growth during periods of colder ocean temperature. The current results represent a high resolution chronological record of north-east Atlantic cod growth, greatly increasing the prior temporal range of such data, thereby providing a valuable baseline for a broad range of studies on Atlantic cod growth.

    In order to pave the way towards regional security and arms control in North-East Asia, one of the outstanding issues left over from the cold war, that is, the question of a divided Korea-must be solved first. In settling the Korean problem, the importance of the bilateral negotiation between the parties in direct conflict can never be overemphasized. Over the past few years, fortunately, there has been an accumulation of developments that would have a positive effect on the improvement of inter-Korean relations and peaceful unification of the peninsula. In this sense, the first challenge for the two Koreas is to fulfil the pledges that they committed in the agreements. Concluding agreements is only a first step. They must be implemented fully both in letter and in spirit. Only upon the sincere and complete translation of the agreements into action can the two Koreas establish a solid peace system and move towards unification. This fulfilment will eventually contribute to security and stability in North-East Asia. To emphasize the importance of bilateral negotiation between the two Koreas is not necessarily to exclude the role of external Powers. The four major Powers in North-East Asia-China, Japan, Russia and the United States - could support the South-North dialogue, help ease tensions, facilitate discussion of common security concerns and possibly guarantee the outcomes negotiated between the two Koreas. By fostering bilateral negotiation between the parties to the conflict, they could contribute to enhancing security, confidence and disarmament in the region. At this moment, the most urgent task in the Korean peninsula relates to the problem of Pyongyang's nuclear weapons programme. To solve the nuclear problem, a significant progress on mutual reciprocal inspections must be made immediately in accordance with the wordings of the Declaration. Mutual inspection will test whether Pyongyang intends to go towards nuclear weapons, or away from them and towards

  5. GIS Applied to Landslide Hazard Mapping and Evaluation in North-East Wales

    Slope instability is a significant environmental hazard in North-East Wales, responsible for important damage to roads and built-up areas. During the late 1980s and the 1990s, systematic landslide mapping and hazard modelling was completed for a number of landslide prone areas within Great Britain, but no such study has to date been carried out for North Wales. This research reports on the creation of a digital landslide inventory for North-East Wales and the use of a Geographical Information System (GIS) to create the first landslide susceptibility models for the area. The research has resulted in the most comprehensive landslide inventory of North-East Wales completed to date. This was accomplished through a combination of aerial photograph interpretation, field mapping and data collection from secondary sources (e.g. consultancy reports, newspapers), yielding a database that records 430 landslides for the area. This represents a 76% (186 landslides) increase on the number of landslides recorded for the area in the UK national landslides database. The landslides in North-East Wales are almost entirely situated inland, with less than 1% on the coast. Approximately 84% of the landslides occur within drift geology and 16% in solid geology. For the slides of known type, 46% are translational slides, 47% rotational slides, 3% flows, 3% falls and 1% complex failures. The type and distribution of landsliding in the area shows notable differences to that found in areas of similar bedrock geology elsewhere in the UK (e.g. Derbyshire and South Wales). Analysis shows that the main landslide controlling parameters in North-East Wales are: lithology, drift material, slope angle, proximity to known faults (structural weaknesses) and proximity to fluvial channels (undercutting). These factors were weighted statistically based on their estimated contribution to slope instability, and combined to create the landslide susceptibility models using a statistical (multiple logistic

    Background: The study aims to highlight common indications as well as outcome of treatment among patients with tracheostomy in Ilorin, North-Central Nigeria. Methods: A review of clinical records of all patients with tracheostomy over a period of ten years (2002-2011), using the Theatre, Ward, ICU and the emergency register after approval from the ethical review committee. Data retrieved included; demographic profile, primary diagnosis, indication for tracheostomy, surgical technique, hospital admission and care outcome of management. All information retrieved input and analysed using an SPSS version 17.0 and data analyzed descriptively. Results: Seventy-six patients had complete data for analysis, age range from 1-89yrs, and mean age of 41.9yrs. There are 48males and 28 females with M:F ratio of 1.6:1. Majority of the patients were in the 3rd–5th decade. About 47.4% had temporary tracheostomy. The commonest indication for tracheostomy is upper airway obstruction secondary to aerodigestive tract tumors in 60.5%, then trauma in 26.3%. The complications are higher among the under tens’. Out of the 36 temporary tracheostomy only 18 were successfully decannulated. The mean hospital stay was 22±2days. Overall 15% mortality was recorded. Conclusion: Common reason for tracheostomy is essentially same earlier documentation in developing countries, common among males, emergency type still most common, neoplasm, prolonged intubation and trauma are the commonest indications, its complication is still high among the under tens’. The outcome is good with 15% mortality due to the primary disease and not from tracheostomy. PMID:29363628

    Full Text Available Background and Objective: Advances in laparoscopy are making the service accessible even in resource-poor countries where adaptations are made to meet local challenges. We report our experience in the provision of laparoscopy service to children at a tertiary health center in North-central Nigeria. Methods: A team of pediatric surgeons, anesthetists, and nurses collaborated to provide service and train other personnel. A prospective collection of data on biodata, diagnoses, procedure, and outcome over an effective period of 36 months of laparoscopy intervention of the 54 months between September 2009 and February 2014 was done. Consent, which also included the possibility of conversion to open was obtained from the parents of the patients. Results: A total of 73 patients aged 2 weeks to 16 years with a male: female ratio of 3 to 1 had laparoscopy done during the period. Fifty-two (71.2% procedures were therapeutic, and 21 (28.8% cases were done as emergency. Laparoscopic appendectomy was the most commonly performed procedure 25 (34.3%, followed by laparoscopic orchidopexy 17 (23. 3%, and diagnostic laparoscopy for disorders of sexual differentiation in 13 (17.8%. The length of stay in hospital postoperative was 1-3 days with a mean of 1.34 ΁ 0.45 days. The complications recorded included hemorrhage, in a case of infantile hypertrophic pyloric stenosis due to failed electrocautery, one port site burns injury from diathermy dissection, and two periport pain postoperation. There was no mortality recorded. Conclusion: Pediatric laparoscopic service is gaining recognition in our practice in spite of poor resources, incessant industrial actions, and apathy from support staff. The outcomes are encouraging as the patients had minimal morbidities. Skills are improved through practice and retraining and manpower, and instruments are being expanded through our collaboration and training.

The study aimed at providing baseline information that may be used in planning a control policy against equine brucellosis. Blood samples were collected from 601 donkeys, comprised of 374 males and 227 females from the six agricultural zones of the state between March 2013 and September 2014. The sera obtained were tested for Brucella antibodies using Rose Bengal plate test (RBPT) and competitive enzyme-linked immunosorbent assay (cELISA). Of the 601 donkeys tested, 43 (7.2%) and 40 (6.7%) were seropositive by RBPT and cELISA, respectively. A seroprevalence of 8.6% was obtained in male and 3.5% in female donkeys. According to age, the highest seroprevalence of 9.6% was obtained from donkeys of age group 4-6 years. With respect to pregnancy status, a higher seroprevalence (6.8%) was obtained from pregnant donkeys compared to 3.8% obtained from the non-pregnant ones. There were statistically significant associations between the presence of antibodies and sex (p  0.05) was observed between the pregnancy status and presence of antibodies. The study concludes that Brucella infection is present in donkeys in all the agricultural zones of the state. The relatively high seroprevalence (7.2%) obtained is of public health concern because of the close interaction between donkeys, ruminants, and humans in the study area.

    The study aims to highlight common indications as well as outcome of treatment among patients with tracheostomy in Ilorin, North-Central Nigeria. A review of clinical records of all patients with tracheostomy over a period of ten years (2002-2011), using the Theatre, Ward, ICU and the emergency register after approval from the ethical review committee. Data retrieved included; demographic profile, primary diagnosis, indication for tracheostomy, surgical technique, hospital admission and care outcome of management. All information retrieved input and analysed using an SPSS version 17.0 and data analyzed descriptively. Seventy-six patients had complete data for analysis, age range from 1-89yrs, and mean age of 41.9yrs. There are 48males and 28 females with M:F ratio of 1.6:1. Majority of the patients were in the 3rd-5th decade. About 47.4% had temporary tracheostomy. The commonest indication for tracheostomy is upper airway obstruction secondary to aerodigestive tract tumors in 60.5%, then trauma in 26.3%. The complications are higher among the under tens'. Out of the 36 temporary tracheostomy only 18 were successfully decannulated. The mean hospital stay was 22±2days. Overall 15% mortality was recorded. Common reason for tracheostomy is essentially same earlier documentation in developing countries, common among males, emergency type still most common, neoplasm, prolonged intubation and trauma are the commonest indications, its complication is still high among the under tens'. The outcome is good with 15% mortality due to the primary disease and not from tracheostomy.

    Full Text Available Background: Snake bite with envenomation is a medical emergency. Children are at risk of severe manifestations due to small body mass. Unlike adult population, there is limited data on snake bite among children in Sokoto, North-Western Nigeria. We described the presentation and outcome of snake bite in children presenting to the Emergency Pediatric Unit of Usmanu Danfodiyo University Teaching Hospital, Sokoto. Materials and Methods: Case records of all children managed for snake bites from 1 st January 2003 to 31 st December 2012 were retrospectively reviewed. Demographic and other relevant information were retrieved and data analyzed using Microsoft Excel. Results: Out of 23,570 Pediatric admissions, 36 children had snake bites giving prevalence of 0.0015 (1.5/1000. Male: Female ratio was 1.6:1, with a mean (standard deviation age of 9.6 ± 2.8 years (range = 1-14 years. Snakebites involved the lower limbs in 52.8%; and at home in 69.4%, and during the night in 58.3% of patients. The highest prevalence of bite was between April and July. Features of envenomation included local swelling (100%, prolonged clotting time (61.1% and spontaneous hemorrhage (epistaxis and hematemesis in 11.1%. One patient (2.8% had seizure which may be incidental, though common causes such as hypoglycemia, malaria and meningitis were excluded by laboratory investigations. Polyvalent anti-snake venom was administered in 29 (80.6% children, with adverse reaction observed in 13.8% (4/29 of the patients. Thirteen patients (36.1% signed against medical advice while the remaining 23 (63.9% were discharged home. Conclusion: Snake envenomation is associated with low morbidity and mortality in our study. Measures aimed at eliminating snake habitats around residential areas should be encouraged.

    Interdisciplinary team working could facilitate the efficient provision and coordination of increasingly diverse health services, thereby improving the quality of patient care. The purpose of this study was to describe knowledge of interdisciplinary team working among obstetricians and gynecologists in two teaching hospitals in South East Nigeria and to determine their attitude toward an interdisciplinary collaborative approach to patient care in these institutions. This was a questionnaire-based cross-sectional study. Data analysis involved descriptive statistics and was carried out using Statistical Package for the Social Sciences software version 17.0 for Windows. In total, 116 doctors participated in the study. The mean age of the respondents was 31.9±7.0 (range 22-51) years. Approximately 74% of respondents were aware of the concept of interdisciplinary team working. Approximately 15% of respondents who were aware of the concept of interdisciplinary team working had very good knowledge of it; 52% had good knowledge and 33% had poor knowledge. Twenty-nine percent of knowledgeable respondents reported ever receiving formal teaching/training on interdisciplinary team working in the course of their professional development. About 78% of those aware of team working believed that interdisciplinary teams would be useful in obstetrics and gynecology practice in Nigeria, with 89% stating that it would be very useful. Approximately 77% of those aware of team working would support establishment and implementation of interdisciplinary teams at their centers. There was a high degree of knowledge of the concept and a positive attitude toward interdisciplinary team working among obstetricians and gynecologists in the study centers. This suggests that the attitude of physicians may not be an impediment to implementation of a collaborative interdisciplinary approach to clinical care in the study centers.

    There has been an increasing interest by couples in child adoption due to its acceptability in recent times in our locale. The enactment of the Child's Right Act in Nigeria has harmonized child adoption process across the nation. With the rising demand for babies from child care institutions by many Nigerian couples, there is need to ascertain their perception of child adoption. To evaluate the perception of child adoption among parents/care-givers of children attending Pediatric Clinics in Enugu. The parents and care-givers of children attending pediatrics out-patients clinics in Enugu, Enugu State, South East, Nigeria served as the respondents. Two hundred and fifty nine of them were selected by convenience sampling method after obtaining their informed written consent. The data were obtained using semi - structured questionnaire that was administered by an interviewer and subsequently analyzed using SPSS Version 15.0. Many caregivers (respondents) (94.2.7%) had heard of child adoption and 79.2% of them understood the actual meaning of the term child adoption. About 1.9% of them had adopted previously. Majority of the respondents (73.87%) prefers to adopt a child during its neonatal age with a slight preference for adoption of male babies. 15.1% and 8.9% of the respondents gave private hospitals and middle men, respectively, as sources of child adoption. Knowledge of the Government adoption laws and process was generally below average (49.2%) among the respondents. Continued advocacy and public enlightenment campaigns should be strengthened in order to harmonize adoption process in our setting.

    Full Text Available Abstract Background There is little existing knowledge about actual quality of drugs provided by different providers in Nigeria and in many sub-Saharan African countries. Such information is important for improving malaria treatment that will help in the development and implementation of actions designed to improve the quality of treatment. The objective of the study was to determine the quality of drugs used for the treatment of malaria in a broad spectrum of public and private healthcare providers. Methods The study was undertaken in six towns (three urban and three rural in Anambra state, south-east Nigeria. Anti-malarials (225 samples, which included artesunate, dihydroartemisinin, sulphadoxine-pyrimethamine (SP, quinine, and chloroquine, were either purchased or collected from randomly selected providers. The quality of these drugs was assessed by laboratory analysis of the dissolution profile using published pharmacopoeial monograms and measuring the amount of active ingredient using high performance liquid chromatography (HPLC. Findings It was found that 60 (37% of the anti-malarials tested did not meet the United States Pharmacopoeia (USP specifications for the amount of active ingredients, with the suspect drugs either lacking the active ingredients or containing suboptimal quantities of the active ingredients. Quinine (46% and SP formulations (39% were among drugs that did not satisfy the tolerance limits published in USP monograms. A total of 78% of the suspect drugs were from private facilities, mostly low-level providers, such as patent medicine dealers (vendors. Conclusion This study found that there was a high prevalence of poor quality drugs. The findings provide areas for public intervention to improve the quality of malaria treatment services. There should be enforced checks and regulation of drug supply management as well as stiffer penalties for people stocking substandard and counterfeit drugs.

    Vaccines are biological products and their efficacy is affected by storage conditions. They are vital in promoting public health. Failures in immunization programmes often times are blamed on disruption in vaccine cold-chain. This study assessed the immunogenicity/potency of the measles vaccines utilized in childhood immunization in South-East, Nigeria and indirectly assessed the effectiveness of the cold-chain technology in the region. This was an experimental study carried out between December 2011 and June 2013. Antibody induction method was used to evaluate the immunogenicity/potency of the measles vaccines sourced from the central cold chain facilities in South-east, Nigeria and indirectly, the effectiveness of the cold chain technology in the zone in maintaining vaccine potency. The neutralizing antibodies in a control group (administered with measles vaccines stored at 37°C for 12 months) and in immunized group were determined after 30 days of immunization using ELISA. The mean storage temperature of the vaccines at the states vaccines central cold chain facilities was -2.4°C and before storage at study site, it was 5.8°C but at the study site it was -4.54°C. Mean ±Standard Error in the Mean (SEM) IgG titers for the measles vaccines sourced from "Open Market", Ebonyi, Enugu, Imo, Anambra and Abia States were 0.793±0.051, 1.621±0.015, 1.621±0.015, 1.715±0.081, 1.793±0.051 and 1.683±0.078 respectively while the mean ±Standard Error in the Mean (SEM) IgM titres were 0.857±0.037, 1.400±0.030, 1.391±0.032, 1.339±0.037, 1.405±0.066 and 1.279±0.025 respectively. One way analysis of variance shows that there is statistical difference in the IgG and IgM antibodies titers produced by the control compared to the vaccines (P value cold-chain technology in the region was judged to be optimal as at the time of vaccine sampling since all the measles vaccines had good immunogenicity profile. However, efforts are still needed to maintain these facilities in

    The understanding of the opinions of the Nigerian public about epilepsy and its treatment is relevant to the reduction of the large treatment gap that exists in management of the condition. The major aim of this study was to determine the knowledge and attitudes of urban dwellers to epilepsy and its treatment and to identify the gaps in knowledge that could pose as barriers in the treatment and care of epilepsy patients within the community. This cross-sectional and descriptive study was carried out in one of the districts of Enugu metropolis, Nigeria. Data collection was by means of a semi-structured validated questionnaire. The mean score in knowledge was low, 48.1±18.8%; higher in females (50.6±18.6%, p=0.03 and those who had witnessed seizures in the past 49.7±18.8, p<0.01. On attitudes, 61.8% of the respondents accepted that it is right if sufferers married but most (93.2%) would not marry them and 87.2% would not allow them to have children or make a new acquaintance by working or playing with them (72.8%). There were no significant differences in the attitude scores of respondents with different levels of education. The level of knowledge of epilepsy in among urban dwellers in SE Nigeria is low and fraught with misconceptions and gaps. There were no significant differences in the attitude scores of respondents with different levels of education. There is a need for a multi-faceted educational interventions directed at improving the awareness and understanding of the condition by all segments of the society.

    Full Text Available Background: Substantial evidence supports a causal relationship between the risk of human breast cancer and levels of endogenous estrogens. Aim: To evaluate the urinary estrogen of women on contraceptives and also compare the levels in two different classes of contraceptives; hence, the possible predisposition of such women to the risk of breast cancer. Setting and Design: Urinary estrogen level was evaluated in 84 women attending family planning clinic in University of Nigeria Teaching Hospital Enugu, Nigeria, who have been on contraceptive device for 10 years or less (≤10 years. They were aged between 21 and 50 years and were divide into three groups (21-30 years, 31-40 years, and >40 years. The control group consisted of 30 age-matched apparently-healthy women who were not on any contraceptive device. Materials and Methods: Estrogen was analyzed using Ecologenia; Estrogen (E1/E2/E3 microplate enzyme-linked immunosorbent assay (ELISA kit, Batch No. T2GR4, from Japan Envirochemicals Ltd, Japan. Statistical Analysis Used: Significant differences between means were determined by two-tailed Student′s t-test using graph pad prism computer software program. Result: There was a statistically significant increase (P=0.0462, in the mean urinary estrogen level of women on contraceptives when compared with the control. The highest amount of estrogen was excreted by the women in the 21-30 years age group. When the contraceptive devices were divided into two classes of intra-uterine device and oral/injectables, there was no statistical difference (P=0.8112 in the mean urinary estrogen output of the women. Conclusion: The synthetic estrogen content of contraceptive device most probably contributed to the level excreted in the urine. The increased estrogen output observed in women on contraceptive device was not dependent on the class of contraceptive device used.

    Prospecting for high grade uranium deposits in North-East Nigeria has, over the years, amongst other reasons, been handicapped by lack of adequate understanding of the elemental primary and secondary dispersion patterns associated with known occurrences in the region. One hundred and forty-four samples from low grade Uranium occurrences at Gubrunde horst consisting of disseminated ores and host rocks, bark and soil samples were therefore, analysed for forty-four elements using Neutron Activation Analysis (with Gamma Spectrometry - INAA and Delayed Neutron Counting - DNC) and Energy Dispersive X-ray Fluorescence Techniques. The analytical data have been evaluated using multivariate statistical techniques. The results show some major element groupings (association). The first group consists of Ph, Ba, Ce and Sm (LREE) that are enriched with increasing uranium concentration in the mineralized zone and are therefore, capable of serving as path-finder elements for uranium. The second group comprising of K 2 O, CaO, Na 2 O and the HREE are depleted in the mineralized zones due to the action of hydrothermal fluids and are indicative of altered/mineralized rocks. The third group consists of the other elements which feature little or no significant enrichment with uranium but may be associated with ferruginisation (hematite) and possibly refractory minerals. It is found that iron does not correlate well with uranium in this report which may indicate ferruginization and mineralization as two independent processes

    East Asia and North America are the regions most heavily affected by powerful cyclones. In this paper we investigate the morphological characteristics of ionospheric disturbances induced by cyclones in different continents. The global ionosphere map supplied by the Center for Orbit Determination in Europe (CODE), International Reference Ionosphere Model (IRI) 2012, and Wallops Island ionosonde station data are used to analyse the ionospheric variations during powerful typhoons/hurricanes in East Asia and North America, respectively. After eliminating the ionospheric anomalies due to the solar-terrestrial environment, the total electron content (TEC) time series over the point with maximum wind speed is detected by the sliding interquartile range method. The results indicate that significant ionospheric disturbances are observed during powerful tropical cyclones in East Asia and North America, respectively, and that all the ionospheric anomalies are positive. In addition, the extent and magnitude of travelling ionospheric disturbances are associated with the category of tropical cyclone, and the extent of TEC anomalies in longitude is more pronounced than that in latitude. Furthermore, the maximum ionospheric anomaly does not coincide with the eye of the storm, but appears in the region adjacent to the centre. This implies that ionospheric disturbances at the edges of cyclones are larger than those in the eye of the winds. The phenomenon may be associated with the gravity waves which are generated by strong convective cells that occur in the spiral arms of tropical cyclones. This comprehensive analysis suggests that the presence of powerful typhoons/hurricanes may be a possible source mechanism for ionospheric anomalies.

    Childhood cancers are relatively uncommon in comparison to adult cancers. There is no literature available to shed light on clinic-pathological types and patterns of care for childhood cancers in our population in North-East India. In this analysis we therefore tried to determine the common childhood cancers diagnosed in our institute, clinical profile of the patients, types of treatment and compliance, and median survival estimates. Leukemia was most common, followed by retinoblastoma, central nervous system tumours and lymphomas. Ascertaining the clinic-pathological profile of childhood cancers in our population is essential for allocation and management of resources for this small but important group of patients.

    Most biggest polluters of atmospheric air among Estonian enterprises are located in the north-eastern part of republic. Volatile gases, vapours and fly ash from thermal power plants, chemical and other industries form a considerable aerotechnogenic load upon landscapes and dwelling regions, reaching also the areas of Gulf of Finland, and even the neighbouring states. Complicated pollution situation needs serious attention and systematic air quality control, assessing, forecasting and management, which is now organized on local, regional and state levels. It is well-known that for studies of various pollution situations the atmospheric dispersion models will be used. This present article deals with the special imitation system for maintenance of information about polluters and air contamination state in North-East (NE) Estonia, also for estimation of pollutants spreading and overground concentration fields by computer-based modelling. The system consists of regional Data Banks, imitation model for calculation of pollutants dispersion, common and application programs. (author)

    2002-02-01

    Magnetic anomaly and Bouguer gravity anomaly maps have been prepared over the Hatton-Rockall Basin in the North-East Atlantic. A qualitative interpretation of these maps is presented. Two cross-sectional models have been constructed along lines perpendicular to the axis of the basin. The north-eastern part of the Hatton-Rockall Basin is characterised by circular intrusions and has evolved differently from the southwestern part, which is characterised by linear intrusions that reach the base of the sedimentary sequence. It is proposed that the two parts of the Basin evolved initially along similar lines, and that the southwestern part of the Basin evolved further with a period of extension at the same time as extension between Endymion Spur and Hatton Bank.

The case notes of 212 patients with eclampsia were analyzed with respect to age, parity, type of eclampsia, gestational age, booking status, mode of delivery, and outcome of the babies and mothers. There were 212 cases of eclampsia out of a total of 13,536 deliveries, giving a prevalence of 1.57%. One hundred and sixty (24.5%) of the women were unbooked. Antepartum eclampsia constituted 160 (75.5%) of all types of eclampsia. Nulliparous teenagers were the most commonly affected women--128 (60.4%). Cesarean delivery was higher than vaginal delivery, accounting for 160 (75.5%) of all deliveries. There was a statistically significant relationship between the route of delivery and the parity of the women (χ(2) = 3.60; d = 5; p = 0.035). There were 16 maternal deaths, giving a case fatality rate of 7.5%. There were 12 neonatal and 8 perinatal deaths. Puerperal sepsis occurred in 9.4% of the patients. Eclampsia is a major cause of maternal mortality in Nnewi, rural South East Nigeria. Teenage nulliparous women are most susceptible.

    To determine the prevalence of intestinal parasitosis in one rural village and one urban centre in North Central Nigeria. A total of 111 single stool specimens from all the volunteered rural dwellers and 93 specimens from randomly selected urban dwellers were examined using Formol-ether and modified Ziehl-Neelsen techniques; during the months of June and July 2005. A questionnaire was completed for each subject and the nutritional status of the adults was assessed using the anthropometric measurements (weight and height for age and Biomass index). The results suggest very high prevalence rates of intestinal parasitosis of 72.1% and 69.9% for the rural and urban populations respectively. All the age groups were infected. The males in the rural area had a prevalence of 69.2% as against 74.6% in females (P>0.05); while in the urban area, the males were more significantly infected (77.4%) compared with the females with 66.1% (Pprevalence of 79.3% and 72.4% for the rural and urban populations respectively. The prevalence of the parasites in the rural and urban populations respectively were: Entamoeba coli (16.2% and 9.7%); E. histolytica (18.9% and 18.3%); E. hartmani (1.8% ad 0.0%); Endolimax nana (16.2% and 18.3%); Iodamoeba butschlii (0.0% and 1.1%); Giardia lamblia (7.2% and 4.3%); Schistosoma mansoni (9.9% and 0.0%); Strongyloides stercoralis (0.9% and 0.0%); Hookworm (4.5% and 5.4%); Ascaris lumbricoides (1.8% and 0.0%); Enterobius vermicularis (0.0% and 1.1%); Cryptosporidium parvum (29.7% and 19.4%); and Enterocytozoon bieneusi/Encephalitozoon intestinalis (39.6% and 47.3%). Polyparasitism was recorded in 48.6% of the rural subjects and 36.6% of the urban subjects. The study has shown a very high prevalence of intestinal parasitosis in both the rural and urban populations and that C. parvum and E. bieneusi/E. intestinalis are harboured by apparently healthy individuals.

    In 1994, for the fifth successive year, Total increased its proven reserves of hydrocarbons which reach 4.3 Gboe (+ 6% compared to 1993). Outside the Middle East, the reserves show a development of 9% and reach the threshold of 2 Gboe. In 1994, Total's production of hydrocarbons reached 633,000 boe/d (+ 4%), despite a fall of 3% in oil production in the Middle East. Excluding the Middle East, production was increased to 345,000 boe/d (+ 12%), including 212,000 boe/d for gas (+ 20%). Exploration/production investments were 5.8 GF in 1994 (excluding labour) and the development program for reserves and production for the coming years is based on yearly investments of some 6 GF. Total's production in Europe, essentially in the North Sea, was 154,000 boe/d in 1994 (+ 12%). This zone has potential for significant growth for the group which has undertaken exploration surveys in the Western Shetlands and in Haltenbanken. In the British zone, the Dunbar field and its neighbour Ellon were brought into production in December 1994. In the Norwegian zone, the Froy field, was brought into production last June. In the Lille-Frigg field, whose production started in May, initial reserves are estimated at 6,7 Bcm of gas. Total Norge AS also has interests in the producing fields of Ekofisk, Frigg, East-Frigg, Heimdal, Sleipner East, Veslefrikk, Oseberg, Brage, in those of Sleipner West and Huldra (start-up scheduled for 1997) and in Troll (phase 1) which should be producing in 1996. In the Dutch zone, the K4b and K5a blocks brought into production last November hold reserves estimated at 20 Bcm; their production could reach 2 Bcm/year as from 1995. (authors). 1 tab., 1 photo

    Full Text Available Abstract Background Paracetamol (also known as acetaminophen is the commonest available analgesic and anti-pyretic. It is readily accessed from pharmacy, patent medicine and provision shops as over the counter drug making it a potential drug of abuse, especially in children. We sought to find its use and/or misuse in children seen at the paediatric outpatient clinic of the University of Nigeria Teaching Hospital (UNTH Ituku-Ozalla, Enugu. Objective To determine the dosage, formulation, and frequency of paracetamol administration to children by caregivers and factors associated with its use and/or misuse. Method An observational prospective study involving 231 children and their caregivers seen at the paediatric outpatient clinic of the University of Nigeria Teaching Hospital, Ituku - Ozalla, Enugu between June and November 2011 was undertaken. Data on paracetamol use before presentation to the clinic, in addition to demographic and other data were obtained from the caregivers using a structured questionnaire. Ethical consent for the study was obtained from the Hospital Ethics and Research Committee and informed consent was further obtained from the caregivers of the children. Results A total of 231 children aged six weeks to 16 years and their caregivers participated in this study. The mean ages of the children and their caregivers were 3.8 and 33.9 years, respectively. One hundred and thirty three of the children studied were males while 98 were females. Most of the children (75.6% received paracetamol at home before presenting. Paracetamol tablet alone or in combination with the syrup was mostly used (60% and this observation was made across all age groups. The commonest reason for using paracetamol tablet instead of the syrup was that it was more effective. Most caregivers relied on past experience (71.2% rather than on enclosed information leaflet to decide the appropriate dosage. Half of the children also received other medications

  17. Use Of ProductionService Work In Enhancing Skill Acquisition In Technical Colleges In North Central Nigeria

    Full Text Available Skill acquisition is a critical component of any vocational or technical training program. When this component is missing or falls below expectation it tends to defeat the objectives or the essence of the program. In Nigeria many skill acquisition institutions experience great challenges in trying to provide the necessary facilities required for effective vocational training of those enrolled in their programs because of paucity of funds. The result is that students graduate from the programs without adequate employability skills for meaningful productiveservice work after leaving school. In realization of this shortfall government has directed technical colleges to establish what is called ProductionService Work PSW into its curriculum. This is with the view that in the event that there is shortfall in the supply of training facilities by sponsors of the programs jobs could be brought in from inside or outside the school which could provide opportunity for students to acquire hands-on experience that would equip them with requisite skills for post-graduation work. As laudable as this initiative appears to be many schools in the North Central Nigeria are yet to implement the directive of the federal government in their schools and even where this has been done its implementation does not appear to be viable. Over the years different technical colleges have adopted different approaches toward the establishment and management of productionservice work in their schools. While some have recorded appreciable success in its implementation others seem to exist only in name. The present study therefore sought to identify the current practices employed in the use of PSW in technical colleges the appropriateness of the practices in use and the alternative practices that could be adopted to improve and guide the implementation of the program with a view to enhancing the acquisition of employability skills in technical colleges in North Central Nigeria.

    Ectopic pregnancy remains a leading cause of maternal morbidity and mortality in the first trimester of pregnancy in developing countries. To determine the incidence, pattern of presentation and management of ectopic pregnancies at Federal Medical Centre (FMC) Owerri. This was a retrospective descriptive study of all cases of ectopic gestations managed at FMC Owerri between 1st January 2009 and 31st December, 2013. The case notes were retrieved from the hospital's Records Department and information on socio-demographic characteristics, age, and parity, clinical presentation, findings at laparotomy, estimated blood loss and the need for blood transfusion were obtained. Data were entered into SPSS 17.0 and analysed descriptively. There were 382 cases of ectopic gestations out of the total 9880 total deliveries within the study period. The incidence of ectopic pregnancy was 38.66 per 1,000 live births or I in 26 deliveries. Nulliparous women were 132 (34.5%). At presentation, 99.47% of patients had rupture with haemoperitoneum, with the commonest site being the ampulla of the fallopian tube as seen in 338 (88.4%). Salpingectomy was done in majority of cases, accounting for 355 (93%), while 248 (65%) had blood transfusion. Five (1.3%) maternal deaths occurred during period of study. Ectopic pregnancy presents a major public health challenge among women of reproductive age groups in Nigeria. Efforts should be directed to public awareness on sex education, contraception, prevention and treatment of common risk factors for ectopic pregnancy.

    Full Text Available Purpose: This study aims to determine the prevalence, pattern, and time of presentation for the ocular disorders seen among children attending a pediatric eye clinic in Nigeria. Materials and Methods: A retrospective chart review of all first-time patients at a pediatric eye clinic, within 2005–2007 was carried out. Data on cohort demographics, duration of illness before the presentation, and types of ocular disorders were collected and analyzed. Statistical significance was indicated by P < 0.05. Results: A total of 335 cases were reviewed, comprising 171 males and 164 females. The majority of children were in the 10–14 age group (31.94%. Allergies (40.72% were the most common ocular disorder followed by refractive errors (22.16%, trauma (7.98%, and inflammation/infections (7.98%. Among others, ocular disorders seen in decreasing frequency were ocular motility imbalance (5.41%, tumors (1.28%, and ptosis (0.77%. Least common was juvenile glaucoma (0.51%. Majority (42.09% presented more than 1 year after onset of illness while only 16.2% presented within 1 month of their illness. Conclusion: Most common causes of ocular disorder in this study were allergy, refractive error, and trauma. Majority of the children presented late, and most of the disorders can result in visual impairment/blindness if not treated early. This emphasizes the need for appropriate health education to avert most cases of childhood blindness/visual impairment.

    Dyslipidemia has been noted to play an integral role in the pathogenesis and progression of micro and macrovascular complications in diabetes mellitus patients. The complications exemplified by renal vascular and cardiovascular disease cause the most morbidity and mortality in this group of patients. This study is aimed at understanding the pattern of dyslipidemia among type 2 diabetic patients. A total of 108 consenting adult type 2 diabetic patients seen in the medical unit of the Nnamdi Azikiwe University Teaching Hospital Nnewi were evaluated in this crosssectional study. Their fasting lipid profile, fasting blood glucose, weight, height and blood pressure were evaluated. The prevalence of dyslipidemia (at least one abnormal lipid profile) was 90.7%. The 24.1% had single dyslipidemia while 66.6% had combined dyslipidemia. Reduced HDL constituted the highest single abnormality (62%) followed by hypertriglyceridemia (56.5%), hypercholesterolemia (53.7%) and high LDL in (44.4%). The duration of DM was not significantly associated with dyslipidemia (P > 0.05). Dyslipidemia is highly prevalent among type 2 diabetic patients in Nigeria with the majority of the patients having combined dyslipidemia. We recommend that aggressive treatment of lipidemia and hyperglycemia can be instituted to reduce the risk of macro and microvascular complications.

    Full Text Available Tourism development strategies play an increasingly important role, representing parts of those documents that aim to socio-economic development, undertaken at local, zonal, county, regional or national level. Frequently, tourism is viewed as one the best solutions for economic recovery, but without a detalied and realistic analysis of what territory offers from this point of view, this new trend for resolving the economic dysfunctions remains at a mirage level. The North-East Region of Romania, the fifth less developed region of the European Union, with a GDP per capita (in purchasing power standard that amounted to only 34% of the EU-28 average in 2013, rushes to come with a development strategy for tourism, relying on “relief and environmental factors, diversity and beauty of landscape, cultural heritage”, strengthening the specific offers relying especially on mountain, cultural, and religious tourism. The present study uses multiple research methods (quantitative and qualitative analysis, graphical and cartographical representation of data, comparison in order to establish the reliability of the concerned document and to provide solid arguments for the type of tourism that has the largest premises of affirmation in each county of the North-East Region of Romania.

    The Ukraine crisis has been a 'wake up' call for Europe but its implication in Asia should be also be considered. The Russian 'coup de force' in Ukraine has created a psychological trauma in Western countries not only amongst political and military leaders but also in the general population by its reminiscence of Cold war thinking and by pointing to the risk of a military conflict in Europe. Moreover the Russian attempt to change the borders by force could create a dangerous precedent and produce an undesirable 'butterfly effects' in the rest of the world. In North East Asia, the stability in a context of rising powers and proliferation risks, relies on a status quo based upon the partition of the Korean peninsula, a de facto autonomy of Taiwan and a Japanese administration over the Senkaku-Diaoyu islands. As the status quo is increasingly challenged by revisionist powers, the question is worth to be raised: what are the implications of the Ukraine crisis for security, non-proliferation, and deterrence in North East Asia?

    The objective of this research was to improve self-care and work safety practices among women weavers in North-East Thailand. Action research was used with a sample of 107 weavers and 15 community and local government stakeholders from six rural villages. Formative and summative evaluation was carried out over 10 months following initial implementation of five action plans, and after 5 years. Qualitative data were collected via focus groups, formal and informal interviews and research field notes. Women's self-care issues and safety problems, and weaving-related environmental pollution emerged from the content analyses. Five action plans were created. Results showed that through action research the women were empowered to identify personal and work-related health issues, environmental contamination concerns, and lack of social and community support systems. Over time they developed capacity for working collectively to address these. Five year follow-up revealed many of the changes made were ongoing, and well-integrated into community life. The study reaffirmed the potential for public health or community nurses and other health personnel for enhancing community health status via action research with vulnerable populations; in this case, rural village women weavers in North-East Thailand. © 2012 Wiley Periodicals, Inc.

    The extended Middle East and North Africa (EMENA) region is the world region with the second youngest population, where globalization, migration, information technology, and political changes are contributing to the shaping of sexuality and sexual behaviors. Understanding the various sociocultural, demographic and public health dimensions of sexual and reproductive health of young people is fundamental to understanding the pattern of sexual behavior and the burden of sexually transmitted infections (STIs), including human papillomavirus-related diseases. New norms and forms of marriage have emerged to accommodate the changing trends in sexual behavior of premarital and extra-marital sex, as well as reports of increased prevalence of premarital penetrative and non-penetrative sexual behavior. Despite these trends, the burden of sexual illnesses remains low and is estimated at 7% of the general population being infected with curable STIs. Other STIs, such as herpes simplex virus 2, are also prevalent. The existing policies and health systems remain short of promoting youth reproductive and sexual health. Efforts should address establishing national preventive programmes, such as screening for STIs, primary prevention, comprehensive sexuality education, as well as youth-friendly services.

    In spite of their oceanic habitat, deep diving cetacean species have been found to be affected by anthropogenic activities, with potential population impacts of high intensity sounds generated by naval research and oil prospecting receiving the most attention. Improving the knowledge of the distribution and abundance of this poorly known group is an essential prerequisite to inform mitigation strategies seeking to minimize their spatial and temporal overlap with human activities. We provide for the first time abundance estimates for five deep diving cetacean species (sperm whale, long-finned pilot whale, northern bottlenose whale, Cuvier's beaked whale and Sowerby's beaked whale) using data from three dedicated cetacean sighting surveys that covered the oceanic and shelf waters of the North-East Atlantic. Density surface modelling was used to obtain model-based estimates of abundance and to explore the physical and biological characteristics of the habitat used by these species. Distribution of all species was found to be significantly related to depth, distance from the 2000m depth contour, the contour index (a measure of variability in the seabed) and sea surface temperature. Predicted distribution maps also suggest that there is little spatial overlap between these species. Our results represent the best abundance estimates for deep-diving whales in the North-East Atlantic, predict areas of high density during summer and constitute important baseline information to guide future risk assessments of human activities on these species, evaluate potential spatial and temporal trends and inform EU Directives and future conservation efforts.

    Background: The endemic diseases in the locality which are associated with changes in liver size necessitate sonographic biometry of this organ. Objectives: To establish by ultrasonography the normal limits and variations of the liver size according to age, sex, height, weight, body surface area and body mass index among school age children. Methods: This was a cross-sectional, hospital based study done at university of Nigeria medical center, Nsukka between January 2011 and June 2011. Participants included 947 apparently healthy subjects comprising 496 boys and 451 girls aged 6–17 years. The intra- and inter rater reliability of sonographic measurement of the liver size was determined. The sonographic examination was performed on Shenzhen DP-1100 machine with 3.5 MHz convex transducer. The longitudinal dimension of the liver was obtained in the midclavicular plane with the subject in deep inspiration. The weight and height of the subjects were obtained with the participants wearing light weight street clothes without shoes. Results: Measurement of liver length was reliable within and between sonographers. The mean of the liver length was 116.3 ± 10.6 mm. Dimension of the liver was not statistically different in boys and girls (p > 0.05). Height correlated best with the liver dimension followed by age, body surface area, weight, body mass index, and sex. The percentile curves, normal limits and prediction model of the liver dimension were defined according to height of the subjects. Conclusion: Determination of pathologic changes in the size of the liver necessitates knowing the normal ranges of dimension for the liver especially with respect to height in this population

The infant feeding choices were made jointly by both partners (61.1% in the antepartum period. The HIV status disclosure rate was 89.2%. A large proportion (91.7% practiced exclusive breastfeeding with highly active antiretroviral therapy, and 7.6% practiced mixed feeding because of nonadherence to their choice and national/international recommendations on infant feeding in the context of HIV/AIDS. This was mainly a result of pressure from family members (42.8% and cultural practices (28.5%. Multivariate logistic regression analysis indicates that adherence was strongly associated with age, marital status, and employment status, but not with residence, educational status, or parity.Conclusion: Exclusive breastfeeding is predominately the infant feeding choice among HIV

    Human immunodeficiency virus (HIV) has spread widely among injecting drug users (IDUs) in countries to the north and west of the 'Golden Triangle' region of South-East Asia; it is likely to have spread southwards to Malaysia as well. In order to assess HIV seroprevalence among IDUs in north-east Malaysia and describe risk factors for HIV infection in this population, we performed a cross-sectional seroepidemiological study among 210 IDUs recruited at the detoxification ward of the General Hospital in the capital city of the north-eastern Malaysian state, Kelantan. Subjects were sequential entrants to the detoxification ward, interviewed about HIV risk behaviour, and tested for antibody to HIV and to syphilis. Nearly a third (62/210, 30%) of these IDUs were HIV seropositive. Three-quarters (159/210) had travelled to Thailand in the preceding 5 years, of whom 32% (51/159) were HIV seropositive; this was associated with injecting in Thailand, but not with sexual contact there. Of those who had not left Malaysia in the preceding 5 years, 26% (11/43) were HIV seropositive, a rate not significantly different from those who had travelled. Travel within Malaysia was common (144/210, 69%) among IDUs interviewed, as was unsafe injecting and unsafe sexual behaviour (20% had shared injecting equipment and 21% had had unprotected intercourse) in other states. In every locale, rates of unsafe injecting behaviour were high (55% sharing in last month), even among those who knew they were HIV infected, and rates of condom usage were low (93% of 160 sexually active IDUs had never used a condom). Syphilis was not associated with HIV infection, but with contact with Thai prostitutes.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. A Robustness Analysis of CMIP5 Models over the East Asia-Western North Pacific Domain

    Full Text Available The Coupled Model Intercomparison Project (CMIP is an international community-based infrastructure that supports climate model intercomparison, climate variability, climate prediction, and climate projection. Improving the performance of climate models over East Asia and the western North Pacific has been a challenge for the climate-modeling community. In this paper, we provide a synthesis robustness analysis of the climate models participating in CMIP-Phase 5 (CMIP5. The strengths and weaknesses of the CMIP5 models are assessed from the perspective of climate mean state, interannual variability, past climate change during the mid-Pliocene (MP and the last millennium, and climate projection. The added values of regional climate models relative to the driving global climate models are also assessed. Although an encouraging increase in credibility and an improvement in the simulation of mean states, interannual variability, and past climate changes are visible in the progression from CMIP3 to CMIP5, some previously noticed biases such as the ridge position of the western North Pacific subtropical high and the associated rainfall bias are still evident in CMIP5 models. Weaknesses are also evident in simulations of the interannual amplitude, such as El Niño-Southern Oscillation (ENSO-monsoon relationships. Coupled models generally show better results than standalone atmospheric models in simulating both mean states and interannual variability. Multi-model intercomparison indicates significant uncertainties in the future projection of climate change, although precipitation increases consistently across models constrained by the Clausius-Clapeyron relation. Regional ocean-atmosphere coupled models are recommended for the dynamical downscaling of climate change projections over the East Asia-western North Pacific domain.

    Tuberculosis remains a global public health problem. In 2011, tuberculosis incidence was 133 per 100,000 in Nigeria. In Nigeria, little is known about the factors associated with tuberculosis, especially in the northern part and only few studies have characterized the Mycobacterium species that cause tuberculosis infection in humans. This study determined factors associated with tuberculosis and identified Mycobacterium species causing human tuberculosis in North-West, Nigeria. We conducted a hospital based case control study between April and July 2010 in Zaria. Cases were newly diagnosed sputum smear-positive tuberculosis patients >15 years while controls were patients >15 years attending the hospital for other reasons but were negative for tuber-culosis. We used a structured questionnaire to obtain information on demographics, knowledge of transmission of tuberculosis, and exposure to some factors. We preformed descriptive, bivariate and backward elimination logistic regression. Sputa from cases were analyzed by multiplex polymerase chain reaction (PCR) based on genomic regions of difference. The mean ages of the cases and controls were 36, standard deviation (SD) 9.0 and 36, SD 9.7 respectively. Only 10 (9.8%) and nine (8.8%) of cases and controls respectively had a good knowledge of the transmission of tuberculosis. Contact with a tuberculosis patient (adjusted odds ratio (AOR) 12.3, 95% confidence interval (CI) 5.2-28.8), consumption of unpasteurized milk (AOR 6.4, CI 2.4-17.2), keeping pets (AOR 5.6, CI 2.3-13.7), associating closely with cattle (AOR 5.6, CI 1.3-6.8), and overcrowding (AOR 4.8, CI 1.8-13.1) were significantly associated with tuberculosis. Of the 102 sputa analyzed, 91 (89%) were M. tuberculosis, 8 (7.8%) were M africanum. We identified possible opportunities for intervention to limit the spread of tuberculosis. We recommend that the Nigeria tuberculosis control program consider some of these factors as a way to mitigate the spread of

    Background: Although, antenatal care (ANC) attendance in sub Saharan Africa is high, however this does not always translate into quality ANC care service utilization. Aim: This study therefore is aimed at exploring pattern of maternal health (MH) services utilization and the socio-demographic factors influencing it in Anambra State, South East Nigeria. Subjects and Methods: A total of 310 women of reproductive age with a previous history of gestation attending ANC services between September, 2007 and August, 2008 in selected Primary Health Centers in Anambra State were studied. Responses were elicited from the study participants using a pre-tested, semi-structured interviewer-administered questionnaire. Data collected were analyzed using Statistical Package for Social Sciences (SPSS) version 17 (SPSS Inc, Chicago Illinois, USA). Association between socio-demographic characteristics and pattern of utilization of ANC and delivery services was measured using χ2-test, Regression analysis was done to identify factors associated with utilization of MH services. P < 0.05 was assumed to be significant. Results: Use of health facility was 293 (97.0%) and 277 (92,7%) out 302 women for ANC and delivery services respectively. Most women attended their first ANC consultation during the preceding pregnancy was after the first trimester and about 31% (94/298) of them had <4 ANC visits prior to delivery. Socio-demographic factors were found to be significantly associated with places where MH care services are accessed. Parity was found to be associated with timing of ANC booking and number of ANC attendance (χ2 = 9.49, P = 0.05). Odds of utilizing formal health facility for MH services were found to be significantly associated with increasing age (P < 0.01) and educational status of mothers (P < 0.001). Conclusions: The study revealed high maternal service utilization and 10% fetal loss, hence the need to address the gaps of late ANC booking and low ANC visits. PMID:24971212

    Background Biofuels and other cooking fuels are used in households in low- and middle-income countries. Aim To investigate the impact of cooking fuels on lung function in children in urban and rural households in South-East Nigeria. Methods The multi-stage sampling method was used to enroll children exposed to cooking fuel in the communities. Lung function values FEV1, FVC and the FEV1/FVC ratio, were measured with ndd EasyOne R spirometer. Airflow limitation was determined with FEV1/FVC Z-score values at -1.64 as the lower limit of normal (LLN5). The Global Lung Function Initiative 2012 software was used to calculate the lung function indices. Results The median age (range) of the 912 children enrolled was 10.6 years (6-18). Altogether, 468 (51.6%) children lived in rural areas. Seven hundred and thirty-seven (80.7%) were directly exposed to cooking fuels (418/737, 56.5% in rural areas). Wood and kerosene were the dominant fuels in rural and urban households. The respective mean Z-scores of the exposed children in rural and urban were zFEV1 -0.62, FVC -0.21, FEV1/FVC -0.83 and zFEV1 -0.57, zFVC -0.14, FEV1/FVC -0.75. Few (5.2%, 38/737) of the children had airflow limitation. Most of them (60.5%, 25/38) lived in the rural community; the lowest FEV1/FVC Z-scores were those of exposed to a combination of fuels. Conclusion Exposure to cooking fuels affects lung function in children with airway limitation in a small proportion, Control measures are advocated to reduce the morbidity related to cooking fuels exposure.

    Full Text Available Abstract Background The north-east Indian states of Manipur and Nagaland are two of the six high HIV prevalence states in the country, and the main route of HIV transmission is injecting drug use. Understanding the pathways to injecting drug use can facilitate early intervention with HIV prevention programs. While several studies of initiation into injecting drug use have been conducted in developed countries, little is known about the situation in developing country settings. The aim of this study was to increase understanding of the contextual factors associated with initiation into injecting drug use in north-east India, and the influence of these factors on subsequent initiation of others. Method In mid 2006 a cross-sectional survey among 200 injecting drug users (IDUs was undertaken in partnership with local NGOs that provide HIV prevention and care services and advocacy for IDUs in Imphal, Manipur and Dimapur, Nagaland. The questionnaire elicited detailed information about the circumstances of the first injection and the contexts of participants' lives. Demographic information, self-reported HIV status, and details about initiation of others were also recorded. Results Initiation into injecting drug use occurred at 20 years of age. The drugs most commonly injected were Spasmo-proxyvon (65.5% and heroin (30.5%. In 53.5% cases, a needle belonging to someone else was used. Two-thirds (66.7% had used the drug previously, and 91.0% had known other IDUs prior to initiation (mean = 7.5 others. The first injection was usually administered by another person (94.5%, mostly a friend (84.1%. Initiation is a social event; 98% had others present (mean = 2.7 others. Almost 70% of participants had initiated at least one other (mean = 5 others. Initiation of others was independently associated with being male and unemployed; having IDU friends and using alcohol around the time of initiation; and having been taught to inject and not paid for the drug at the

    We have studied with the students our climate variability in the last 55 years (1956-2010) to better understanding the feedback between the interlinked terrestrial and atmospheric processes on different spatial and temporal scales. We did case studies of regional hydrological behavior in climate sensitive and drought or flood regions in the North-East of Romania. In the classroom at the "Costache Negruzzi" National College Iasi we have studied with our students, aged 14-18 years old, the temporal and spatial distribution of the precipitation and the temperature in a 55 years period, between 1956-2010, in the North-East of Romania, especially at the meteorological station in Iaši. We did graphs with the observational data from the National Meteorological Agency of Romania about precipitation and air-temperature in our region climate and we have registered our own data with an automatic meteorological station placed in the "Costache Negruzzi" schoolyard. In the classroom we have represented the annual medium precipitation and the temperature variability in graphics registered between 1970-2010, in the area of Iasi-Moldavia, Romania. We have identified four dangerous levels of precipitation especially for flood and drought regions in the North-East of Romania. We have studied the maximal and minimal level of the daily, monthly and annual precipitation in correlation with the temperature variability graphs in the same area. We have realized with the students a very complex analysis on the frequency, repartition and variation in time of the precipitation and we have used the information in the Physics and Geography classes. The students aged 14-18 years old did computing statistics of the meteorological data and did different graphs for the precipitation intensity and frequency on special levels: medium, minimum and maximum. The students applied the data for annual precipitation level in each month, 1970-2010 period and discuss the results to identify the climate

    This study focuses on the Neogene alluvial fan deposits at the North- East of Malatya (Eastern Turkey). These alluvial fan sediments are largely the products of stream deposition during Upper Miocene - Pliocene. Previous sedimentary studies suggest that most of the alluvial input into the basin was from the the north, northeast, and east. Paleozoic-Mesozoic Metamorphics, the Oligocene - marine sediments, the Miocene Yamadaǧ Volcanics, and Neogene alluvial and intercalated lacustrine rocks comprise the main lithologic units in the area. Alluvial sediments are ocur in successive mudstone, sandstone and conglomerates. Macroscobic determinations show that clastics in the alluviums are derived from Yamadaǧ Volcanics which are at the north, northeast, and east of the alluviums. Previous petrographic studies show that these volcanics are composed of basaltic andesite to dacite in composition with typical calc-alkaline character. The aim of this study is to interpret the mineralogical and geochemical characteristics of source area of these alluviums. Samples were collected from these alluvial fan alluviums, and X - ray powder diffraction (XRD), ICP-AES, ICP-MS were performed on these samples, Samples consist of clay minerals, calcite, feldspar, quartz and dolomite. Clay minerals were smectite, illite, mixed layer smectite-illite,and palygorskite, with Ca-smectite being the dominant clay phase. Smectite was derived from the transformation of volcanic glass and volcanic rock fragments. These samples are convenient with Fe shales and shales. The ratios of Zr/TiO2, Th/Sc, Zr/Sc, Y/Ni-Cr/V, Al/(Al+Fe+Mn) show dominance of neutral-basic volcanism in the area. Chondrite-normalized REE diagram show the presence of REE-bearing accessory minerals resulted in a positive LREE anomaly with respect to chondrite. Eu/Eu* values are between 0.77 and 1.53, (average 1.17). The absence of Eu anomalies shows that our samples are generally neutral-basic in composition. Key Words: Mineralogy

    Full Text Available Malaria, which is transmitted by female Anopheles mosquitoes, is the major cause of mortality among the pregnant women in the sub-Saharan Africa. A ten year study of malaria in pregnancy was carried out in Abuja, North Central Nigeria. Thick and thin blood films were stained with the Giemsa methodology. Of the 16760 pregnant women blood samples, 4571 (27.3% were positive for malaria parasites caused by Plasmodium falciparum. Of the 4571 positive cases, 75 (1.7% had parasite density of >5000 parasites/µl of blood; 148 (3.2% had between 500-5000 parasites/µl of blood; 520 (11.4% had between 50 - 500 parasites/µl of blood; while 3828 (83.7% had between 5-50 parasites/µl of blood. With the current estimate of over 4500 deaths of pregnant women in Nigeria due to malaria annually, we must make deliberate efforts to stop these unacceptable and painful losses. The continued use of malaria rapid diagnostic tests (M-RDTs methodologies should be discontinued because of its negative implications. Therefore, the microscopic laboratory diagnostic component should be included in ANC at all level of health care facility.

    A cross-sectional survey of 765 cattle in 125 nomadic and 375 cattle in 125 sedentary herds was conducted to investigate prevalence and risk factors for contagious bovine pleuropneumonia (CBPP) in the two production systems of Niger State in North Central Nigeria, between January and August 2013. Data on herd characteristics were collected using structured questionnaires administered on herd owners. Serological analysis was conducted using competitive enzyme linked immunosorbent assay (c-ELISA) test. Descriptive, univariate, and multivariate statistical analyses were conducted with OpenEpi version 2.3.1 software. Statistical significance was held at P production systems was 14.0 % (CI 12.1-16.1). Age and agro-ecological zones were significantly (P production. Agro-ecological zone C had the highest sero-prevalence (25.3 %, CI 20.2-31.0). No significant cattle factors were detected in sedentary production. Factors significantly associated with CBPP occurrence at herd-level were contacts with other herds during grazing (P production systems. Sero-diagnosis and risk factor identification should be institutionalized as elements of epidemio-surveillance and control strategies for CBPP, especially in resource-poor pastoralists' settlements in Nigeria.

    The deposition loads of fly ash and sulfur have been high in the North-East Estonia since the late fifties, when the oil shale energetics, chemical and cement industry achieved the remarkable extent. The combined effects of both pollutants have seriously damaged sensitive ecosystems (forest on podsolic soils and bog). Most of sulphur deposition is closely related to the oil shale fly ash deposition. The main effects are related with alkalisation due to accumulation of fly ash components and the Sphagnum growth inhibition due to sulfur load. These effects have the time scale of several years or even more. The pollution loads have been changed during recent 40 years due to launching and reconstruction of enterprises (incl. purification systems) and variations of production capacity. First representative data on air pollution deposition originate from the middle of eighties. Only model estimations could be used to quantify the deposition fluxes before that time, as well as for assessing the future scenarios

    Opportunity for natural selection among five population groups of Manipur in comparison with other North East Indian population has been studied. Crow's index as well as Johnston and Kensinger's index for natural selection were calculated based on differential fertility and mortality. The mortality component was found to be lower compared to fertility component in all the populations which may attribute to comparatively improved and easily accessible health care facilities. However, different selection pressures, artificial and natural, seem to be influencing the selection intensity through induced abortion and spontaneous abortion among the two non-tribal migrant groups: Bamon and Muslims, respectively. This study highlights the probable interaction of artificial and natural selection in determining the evolutionary fate of any population group.

    2002-09-01

    Semi-arid areas are characterized by small water resources. An increasing water demand due to population growth and economic development as well as a possible decreasing water availability in the course of climate change may aggravate water scarcity in future in these areas. The quantitative assessment of the water resources is a prerequisite for the development of sustainable measures of water management. For this task, hydrological models within a dynamic integrated framework are indispensable tools. The main objective of this study is to develop a hydrological model for the quantification of water availability over a large geographic domain of semi-arid environments. The study area is the Federal State of Ceara in the semi-arid north-east of Brazil. Surface water from reservoirs provides the largest part of water supply. The area has recurrently been affected by droughts which caused serious economic losses and social impacts like migration from the rural regions. (orig.)

  10. Building a new energy network in North East Asia. A perspective from post-Fukushima Japan

    Shibutani, Yu

    2012-01-01

    The accident at Fukushima Daiichi Nuclear Power Station (NPS) has accelerated Japan's drive for less dependence on nuclear and fossil energy and more green renewables, which inevitably require a new energy strategy. In this paper, a new strategic scenario for moving 'beyond a single economy' is proposed to incorporate Japan with the North East Asian (NEA) energy market in regards to its electricity grid and natural gas pipeline network while preserving nuclear power by strengthening safety. Suggestions are also made that Japan should open more doors for new comers in a manner of open-access towards member economies of NEA. However, there are persistent geopolitical constraints and risks in NEA. The connection of Japan's energy network to its regional neighbors would avoid the tendrils and tentacles of geopolitics that wrap around NEA, and subsequently provide opportunities to build on common energy interests.

    There is paucity of data on non Hodgkin's lymphoma (NHL) from our population in North-East India. In this retrospective study, patients were consecutively followed-up to see the clinic-pathological pattern of NHL, various responses, and pattern of relapses to first line treatment with chemotherapy. All patients in the present study received standard regimen of cyclophosphamde, doxorubicin, vincristine, prednisolone (CHOP) with or without rituximab (R-CHOP) as per our institutional protocol as first line therapy. Our study has shown that, in our adult population, the majority of NHL cases present with stage II and stage III disease and extra nodal involvement, B-cell lymphomas and diffuse large cell lymphomas being the most common subtypes. International prognostic index was a significant factor for varied responses to treatment. The majority of relapses after complete remission occurred in the first year.

    Full Text Available Stimulating economic growth is one of the key issues of economic sciences. The European Union has developed several policies and has allocated a considerable budget to reduce economic disparities among its members. The states that joined the EU in 2004 and 2007 undertake extensive efforts to align their economy with the community level. But a new problem arises, there is a risk that more economically developed areas absorb more funds that less developed ones, and thus amplifying the disparities within the region. This paper shows that this problem is found in the North-East Region of Romania, and as a consequence additional problems appear, that affect the sustainable economic development.

    This paper presents a SWOT analysis of SEA systems in the Middle East North Africa region through a comparative examination of the status, application and structure of existing systems based on country-specific legal, institutional and procedural frameworks. The analysis is coupled with the multi-attribute decision making method (MADM) within an analytical framework that involves both performance analysis based on predefined evaluation criteria and countries' self-assessment of their SEA system through open-ended surveys. The results show heterogenous status with a general delayed progress characterized by varied levels of weaknesses embedded in the legal and administrative frameworks and poor integration with the decision making process. Capitalizing on available opportunities, the paper highlights measures to enhance the development and enactment of SEA in the region. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The Middle East and North Africa has witnessed a dramatic transformation over the last 30 years caused by rapid urbanization and modernization and significant changes to diet and lifestyle. This review attempts to highlight recent data in regards to ischemic heart disease and its risk factors from the region. Ischemic heart disease is now the leading cause of death in the region. Age at presentation with myocardial infarction and acute coronary syndrome appears to be significantly younger than global averages. Increased rates of all major risk factors including diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle have been noted. Specifically, significant changes to dietary habits and growing epidemic of use of alternative tobacco products are noted. This review article highlights the growing epidemic of ischemic heart disease in the region led by dramatic increases in incidence of its risk factors. This epidemic will require a multipronged approach to address the varied issues and mitigate the growing prevalence of the disease.

  16. Accuracy of teleseismic event locations in the Middle East and North Africa

    1996-12-04

    Seismic characterization at the regional level requires accurate determination of phases and travel times for many combinations of stations and events. An important consideration in the process is the accuracy of event locations. The LLNL Comprehensive Test Ban Treaty Research Program is currently working on data from the Middle East and North Africa, where seismic station coverage is relatively sparse and ``ground truth`` seismic source information is practically nonexistent. In this report the investigator use after shock studies as a source of local ground truth. He evaluates teleseismic location accuracy by comparing hypocenters determined by local networks with those determined teleseismically [e.g. the International Seismological Center (ISC) and the National Earthquake Information Center (NEIC)]. Epicentral locations, origin times, and depth determinations of events from three aftershocks studies (Algeria, Armenia, and Iran) and one local network study (Iran) are compared with ISC and NEIC locations for the same events. The key parameter for the ISC locations is the number of observations used in the location determination. For more than 40-50 observations, the agreement rapidly diminishes and ISC locations can differ from local determinations by as much as 80 km or more. Events in Iran show a distinct bias of ISC location errors toward the northeast; events in Armenia and Algeria show no directional bias. This study shows that only events with ISC M{sub b} {gt} 4.4-4.5 or NEIS M{sub b} {gt} 4.7-4. should be used for compiling travel time information from teleseismic bulletins in the Middle East/North Africa region when locations from the NEIC and ISC bulletins are used.

    This study was designed to see the prevalence of lactose intolerance and symptom correlation following oral lactose challenge in healthy volunteers in the north east part of Bangladesh. Symptoms of abdominal pain, nausea, borborygmi, flatulence, diarrhea and others were noted for 24 hours and blood glucose was estimated at 0 hour and 30 minutes after 50 gm oral lactose load to healthy volunteers. Failure to rise blood glucose level ≥1.1 mmol/l at 30 minutes after lactose intake from fasting level was taken as lactose malabsorption (LM) i.e., lactose intolerance. Sensitivity and specificity of different symptoms were then found out. A total of 171 volunteers (male 123, female 48) with a mean age 34.08 years participated in this study. Lactose intolerance was found among 82.5% (n=141, M=100, F=41) subjects. Symptoms mostly experience by the lactose malabsorbers were diarrhea 93(66.0%), borborygmi 80(56.7%), abdominal pain 31(22.0%) and flatulence 32(22.7%). LM prevalence was found to increase with increasing number of symptoms up to 3 symptoms. A week positive correlation (r=0.205, P=0.007) was found between the number of symptoms and proportion of subjects having positive lactose tolerance test. Lactose intolerance among healthy adults of North East part of our country is as common as in other Asian countries including China and Malaysia. But LM is higher than that of Europeans and south Indians. Diarrhea and borborygmi were mostly associated with LM.

    Full Text Available Aim: To determine the various helminth parasites and associated helminth reservoir status of captive wild ruminants in the semi-arid region of north-eastern, Nigeria. Materials and Methods: Faecal samples were examined for nematode ova by the simple floatation technique using saturated sodium chloride solution as floatation medium. Trematode eggs were examined by the sedementation technique. The modified McMaster technique was used to determine the intensity of helminth infections among the various species of wild ruminants examined, while larval isolation and identification using the modified Baerman’s technique was used to determine the various species of parasites encountered. Results: Out of the 36 samples examined, a high parasite count due to Strongyle infection without the manifestation of overt clinical signs was observed among the captive wild ruminants. The egg counts ranged from 500 + 10.0 among the Grimm’s duicker (Sylvicaprea grimmia to 5, 350 + 51.70 among the Senegal hartebeest (Damaliscus korrigum. The helminth larvae recovered which were common to all the species of wild ruminants were those of Haemonchus contortus, Trichostrogylus axei and Strongyloides papillosus, Demographic data such as age, sex and species of wild animals showed no significant (p>0.05 variation on the prevalence of the helminth infections. Conclusion: The results of this study suggests that the captive wild ruminants in the semi-arid region of north-eastern, Nigeria, were reservoirs of various helminth parasites of medical and veterinary importance. It was therefore, recommended that improved sanitary conditions in animal enclosures, regular and strategic anthelmintic medications may on one hand protect the spread of infection to attendants and visitors to the park. On the other hand it will enhance the in-situ conservation of the rare and endangered species of wild ruminants in the area. [Vet World 2012; 5(9.000: 530-534

    The Neyveli Lignite Corporation (NLC) is among the largest lignite based power plants in South East Asia. The four elevated stacks from this power plant emanate a substantial amount of sulphur dioxide into a tropical boundary layer. Sulphur dioxide being a soluble pollutant gas is absorbed by falling raindrops. This is a first study that aims to quantify the scavenging action of the North Eastern monsoonal rains. Our quantification is based on data obtained from the NLC. In this study we have analyzed observations of precipitation events over southern India and have related the observed precipitation patterns to standard distributions. Thence we calculated the relative abundances of the small and large droplets in the modeled spectra. Having obtained some optimal size distributed raindrop spectra, we then proceeded to quantify the mass transfer rates of the pollutant into the dispersed phase. Since the droplets are embedded in a turbulent boundary layer we had to account for the ventilation effects also. Our study reveals that although the North Eastern monsoonal rains have a preponderance of very large droplets, the contribution of the small droplets cannot be neglected. We expect that the estimated scavenging coefficients can be used by large eddy and climate models.

    The tide-gauge record from the North American East Coast reveals significant accelerations in sea level starting in the late twentieth century. The estimated post-1990 accelerations range from near zero to ∼0.3 mm yr -2 . We find that the observed sea level acceleration is well modeled using several processes: mass change in Greenland and Antarctica as measured by the Gravity Recovery and Climate Experiment satellites; ocean dynamic and steric variability provided by the GECCO2 ocean synthesis; and the inverted barometer effect. However, to achieve this fit requires estimation of an admittance for the dynamical and steric contribution, possibly due to the coarse resolution of this analysis or to simplifications associated with parameterization of bottom friction in the shallow coastal areas. The acceleration from ice loss alone is equivalent to a regional sea level rise in one century of 0.2 m in the north and 0.75 m in the south of this region.

    The Middle East and North Africa (MENA) regional climate appears to be extremely sensitive to volcanic eruptions. Winter cooling after the 1991 Pinatubo eruption far exceeded the mean hemispheric temperature anomaly, even causing snowfall in Israel. To better understand MENA climate variability, the climate responses to the El Chichón and Pinatubo volcanic eruptions are analyzed using observations, NOAA/National Centers for Environmental Prediction Climate Forecast System Reanalysis, and output from the Geophysical Fluid Dynamics Laboratory's High-Resolution Atmospheric Model. A multiple regression analysis both for the observations and the model output is performed on seasonal summer and winter composites to separate out the contributions from climate trends, El Niño-Southern Oscillation (ENSO), North Atlantic Oscillation (NAO), Indian summer monsoon, and volcanic aerosols. Strong regional temperature and precipitation responses over the MENA region are found in both winter and summer. The model and the observations both show that a positive NAO amplifies the MENA volcanic winter cooling. In boreal summer, the patterns of changing temperature and precipitation suggest a weakening and southward shift of the Intertropical Convergence Zone, caused by volcanic surface cooling and weakening of the Indian and West African monsoons. The model captures the main features of the climate response; however, it underestimates the total cooling, especially in winter, and exhibits a different spatial pattern of the NAO climate response in MENA compared to the observations. The conducted analysis sheds light on the internal mechanisms of MENA climate variability and helps to selectively diagnose the model deficiencies.

  8. The Intertropical Convergence Zone over the Middle East and North Africa: Detection and Trends

    This thesis provides an overview of identifying the Intertropical Convergence Zone (ITCZ) in the Middle East and North Africa (MENA) region. The ITCZ is a zone of wind convergence around the equator that coincides with an area of intense precipitation that is commonly termed a tropical rainbelt. In Africa, these two concepts are frequently confounded. This work studies the correlation between precipitation and commonly used ITCZ indicators. A further attempt is made to detect movement in the African ITCZ, based on earlier paleontological studies showing historical changes in precipitation. Zonally averaged wind convergence is found to be the most reliable indicator of the African ITCZ, one having a low correlation with zonally averaged precipitation. Precipitation is found only to be a reliable indicator for the African ITCZ in zones near the wind convergence, which reaches as far north as 20_N in the summer. No secular change in location of the African ITCZ is found for the time of available data. Finally, historical data shows that any increase in precipitation in the Sahel, a region where precipitation is driven by the ITCZ, is mildly negatively correlated with precipitation in the rainbelt area, suggesting that shifts in the ITCZ result in a widening of the precipitation profile as well as a shift of the entire zone.

  9. Foreign Direct Investment and Energy Supply in the Middle East and North Africa: A Correlational Study

    Elghali, Siddig

    Middle East and North Africa countries have been criticized for failing to utilize foreign direct investment energy resources efficiently. The changing of energy resources environment of the past decades with its growing emphasis on the importance of imminent energy supply challenges require strategists to consider different types of energy resources investment to improve energy supply. One type of energy investment will show effectiveness and efficiency in utilizing foreign direct investment in exposing RE, fossil fuels, natural gas, and reducing CO2 emissions. The purpose of this quantitative correlational study was to utilize foreign direct investment to predict total primary energy supply in the Middle East and North Africa region between 1971 and 2013. The study was conducted using a sample size of 43 years of energy supply resources and foreign direct investment from 1971 to 2013, which includes all of the years for which FDI is available. RE potential may equip Middle East and North Africa countries with sustainable and clean electricity for centuries to come, as non-renewable energy resources may not meet the demands globally and domestically or environmentally. As demands for fossil fuels grow, carbon emissions will increase. RE may be a better option of CO 2 emissions sequestration and will increase electricity to rural areas without government subsidies and complex decision-making policies. RE infrastructure will reduce water desalinization costs, cooling systems, and be useful in heating. Establishing concentrated solar power may be useful for the region cooperation, negotiations, and integration to share this energy. The alternative sought to fossil fuels was nuclear power. However, nuclear power depends on depleting, non-renewable uranium resources. The cost of uranium will increase if widely used and the presence of a nuclear plant in an unstable region is unsafe. Thus, renewable energy as a long-term option is efficient. A nonlinear regression

Age specific fertility rates are as high as 121 and 225 per 1,000 for ages 15–19 and 20–24 years, respectively. Only 9.7% of currently married women in Nigeria use modern methods of family planning (FP. This figure, however, does not reveal important age, geographical, or educational differences in Nigeria. The overall purpose of the study is to establish hidden demographic factors that enhance usage of modern methods of FP. Methods: Data for this study were obtained from four waves of the National and State Specific HIV and AIDS, Reproductive and Child Health Survey – NARHS/SARHS (2003, 2005, 2007, and 2011. Data were collected among men and women of reproductive age in the 36 states of Nigeria including Federal Capital Territory (FCT. For the analysis, the study was however limited to North West and South-South zones of Nigeria. Bivariate and multiple logistic regression was performed using SPSS version 20. Results: Use of modern methods of FP has increased over time with an average annual increase of 0.47%. Different age groups, zones, and educational attainment prefer different modern methods of FP. Of all users of modern methods of FP, long lasting methods account for just 3% while condoms account for as high as 58%. Eighty-six percent of sexually active never married women use condoms for FP. Women in South-South Nigeria are over three times and five times more likely to use a modern method of FP and a condom, respectively. Conclusion: Demographic

    Full Text Available Objective: To determine the seroprevalence of brucellosis among cattle in some local government areas (LGA of the northern part of Plateau State, Nigeria. Methods: Sera obtained from a total of 270 randomly selected cattle from different herds in the four selected LGAs were for Brucella antibodies using the Rose Bengal Plate Test (RBPT. Results: An overall brucellosis seroprevalence of 9.6% (26/270 was obtained. The seroprevalence of Brucella antibodies among the cattle across the LGA ranged from 0%-37.3% with Riyom and Bassa LGA having the lowest and highest seroprevalence respectively while Barkin Ladi LGA had no sero-positive cattle. Females had a higher percentage of seropositives compared to males while cattle reared under extensive system of management had a higher (11.6% percentage of sero-positives compared to cattle kept under the intensive system of management. However, there was no statistically significant (P>0.05 association between serological status and sex or management practice. Conclusions: The results of this study indicates that bovine brucellosis is still a problem among the cattle population in Plateau State, Nigeria. And the public and other animals are at risk of exposure to the disease agent in these animals which are still shedding the organism.

    We report eight new U-Pb detrital zircon ages for quartzose metasedimentary rocks from four lithotectonic units of parautochthonous North America in east-central Alaska: the Healy schist, Keevy Peak Formation, and Sheep Creek Member of the Totatlanika Schist in the northern Alaska Range, and the Butte assemblage in the northwestern Yukon-Tanana Upland. Excepting 1 of 3 samples from the Healy schist, all have dominant detrital zircon populations of 1.9–1.8 Ga and a subordinate population of 2.7–2.6 Ga. Three zircons from Totatlanika Schist yield the youngest age of ca. 780 Ma. The anomalous Healy schist sample has abundant 1.6–0.9 Ga detrital zircon, as well as populations at 2.0–1.8 Ga and 2.7–2.5 Ga that overlap the ages from the rest of our samples; it has a minimum age population of ca. 1007 Ma.Detrital zircon age populations from all but the anomalous sample are statistically similar to those from (1) other peri-Laurentian units in east-central Alaska; (2) the Snowcap assemblage in Yukon, basement of the allochthonous Yukon-Tanana terrane; (3) Neoproterozoic to Ordovician Laurentian passive margin strata in southern British Columbia, Canada; and (4) Proterozoic Laurentian Sequence C strata of northwestern Canada. Recycling of zircon from the Paleoproterozoic Great Bear magmatic zone in the Wopmay orogen and its Archean precursors could explain both the Precambrian zircon populations and arc trace element signatures of our samples. Zircon from the anomalous Healy schist sample resembles that in Nation River Formation and Adams Argillite in eastern Alaska, suggesting recycling of detritus in those units.

    Rubella cases are often under-reported, especially in many developing countries, owing to inadequate attention and weak funding of elimination strategies, despite being an epidemic-prone disease. Based on available data, this paper, therefore, seeks to bring the attention of public health practitioners, researchers and policy makers to threats of rubella in our environment, and also recommend measures to mitigate the threats. The authors conducted a retrospective cross-sectional study in which the laboratory results of febrile-rash-illness cases in Kebbi State, Northwest Nigeria, from January 1, 2014 to December 31, 2015 were analysed, using descriptive statistics and chi-square test. We obtained the data set through the routine Integrated Disease Surveillance System and Response being conducted in Nigeria. A total of 413 febrile-rash-illness cases were reported and investigated in Kebbi State from 2014 to 2015, 5 (3.5%) tested positive for rubella IgM in 2014 while 7(2.6%) tested positive in 2015. There was no statistically significant difference in the incidence of rubella between 2014 and 2015 (p> 0.05). Rubella infection was mainly found in children less than 5 years of age with peak incidence period during the hot season (between February and April). There was no significant sex bias in this study. However, our practice experiences in this environment suggest a systematic under-reporting and under-diagnosis of febrile- rash-illnesses. There was no statistically significant difference in the incidence of rubella in children in our setting for the 2-years studied. However, there is a potential for increase in the transmission of the disease due to non-availability of routine childhood vaccination against rubella and the systematic under-reporting of suspected cases and weak laboratory support. In order to better appreciate the burden of rubella infection, there may be a need to undertake a prevalence survey, and simultaneously, strengthening case

    Coesite-bearing zircon formed at ultrahigh-pressure (UHP) conditions share general characteristics of eclogite-facies zircon with trace-element signatures characterized by depleted heavy rare earth elements (HREE), lack of an Eu anomaly, and low Th/ U ratios. Trace-element signatures of zircons from the Caledonian UHP terrane in North-East Greenland were used to examine the possible changes in signature with age during exhumation. Collection and interpretation of age and trace-element analyses of zircon from three samples of quartzofeldspathic gneiss and two leucocratic intrusions were guided by core vs. rim zoning patterns as imaged by cathodoluminesence. Change from igneous to eclogite-facies metamorphic trace-element signature in protolith zircon is characterized by gradual depletion of HREE, whereas newly formed metamorphic rims have flat HREE patterns and REE concentrations that are distinct from the recrystallized inherited cores. The signature associated with eclogite-facies metamorphic zircon is observed in coesite-bearing zircon formed at 358 ?? 4 Ma, metamorphic rims formed at 348 ?? 5 Ma during the initial stages of exhumation, and metamorphic rims formed at 337 ?? 5 Ma. Zircons from a garnet-bearing granite emplaced in the neck of an eclogite boudin and a leucocratic dike that cross-cuts amphibolite-facies structural fabrics have steeply sloping HREE patterns, variably developed negative Eu anomalies, and low Th/U ratios. The granite records initial decompression melting and exhumation at 347 ?? 2 Ma and later zircon rim growth at 329 ?? 5. The leucocratic dike was likely emplaced at amphibolite-facies conditions at 330 ?? 2 Ma, but records additional growth of compositionally similar zircon at 321 ??2 Ma. The difference between the trace-element signature of metamorphic zircon in the gneisses and in part coeval leucocratic intrusions indicates that the zircon signature varies as a function of lithology and context, thus enhancing its ability to aid in

    Bamboo forms an important component in the traditional landscape of North East India. For biomass estimation of village bamboos of Barak Valley, North East India, allometric relationships were developed by harvest method describing leaf, branch and culm biomass with DBH as an independent variable using a log linear model. The culm density of the stand was 8950 culms ha{sup -1} during 2005 of which 67% of growing stock was represented by Bambusa cacharensis, 17.88% by Bambusa vulgaris and 15.12% by Bambusa balcooa. Above ground stand biomass was 121.51 t ha{sup -1} of which 86% was contributed by culm component followed by branch (10%) and leaf (4%). With respect to species, B. cacharensis made up to 46% of total stand biomass followed by B. vulgaris (28%) and B. balcooa (26%). Carbon storage in the above ground biomass was 61.05 t ha{sup -1}. Allocation of C was more in culm components (53.05 t ha{sup -1}) than in branch (5.81 t ha{sup -1}) and leaf (2.19 t ha{sup -1}). Carbon storage in the litter floor mass was 2.40 t ha{sup -1}, of which leaf litter made up the highest amount (1.37 t ha{sup -1}) followed by sheath (0.86 t ha{sup -1}) and branch (0.17 t ha{sup -1}). Carbon stock in the soil up to 30 cm depth was 57.3 t ha{sup -1}. Gross C stock in the plantation was estimated to be 120.75 t ha{sup -1}. Carbon storage estimated in the bamboo stand of present study offers insights into the opportunity of village bamboos in the rural landscape for carbon storage through carbon sequestration. Management and utilization of village bamboos as a potential source of carbon sink by smallholder farmers are discussed in the context of their livelihood security and the Millennium Development Goals of the United Nations.

  17. How well do climate models simulate atmospheric teleconnctions over the North Pacific and East Asia associated with ENSO?

    Science.gov (United States)

    2017-02-01

    During the El Niño and La Niña mature phase, atmospheric teleconnections over the North Pacific and East Asia vary considerably on sub-seasonal time scales, and are strongly phase-locked to the sub-seasonal evolution. In this study, we investigate how well climate models that participated in the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulate the sub-seasonal evolution of teleconnections over the North Pacific and East Asia associated with El Niño-Southern Oscillation (ENSO). In the observations, there is a prominent anticyclone anomaly over the Kuroshio extension region (i.e. Kuroshio anticyclone), which significantly affects East Asian climate in the early winter (November-December) of El Niño years. However, in January, the Kuroshio anticyclone suddenly disappears, and a cyclonic flow dominates over the North Pacific. It is found here that the CMIP5 models simulate the overall extratropical teleconnection patterns, but they fail to reproduce some of these sub-seasonally-varying features in atmospheric circulation. For example, the models tend to simulate a weaker Kuroshio anticyclone in the early winter during El Niño phases, and fail to capture the abrupt decay of the Kuroshio anticyclone in the late winter. We demonstrate here that these systematic errors in ENSO teleconnection can be explained by systematic errors in tropical precipitation associated with ENSO. That is, negative precipitation anomalies over the western North Pacific (WNP) are too weak in the models compared to that in the observations, and their amplitude tends to be strengthened from December to the following January, while they are weakened in the observations. In addition, analyses on the inter-model diversity strongly support that relative magnitudes of WNP and central Pacific precipitation anomalies are critical for determining sub-seasonal evolution of ENSO teleconnections over the North Pacific and East Asia.

  18. Ancient glaciations and hydrocarbon accumulations in North Africa and the Middle East

    2009-04-01

    At least six glaciations are purported to have affected North Africa and the Middle East region over the last one billion years, including two in the Cryogenian (Neoproterozoic), Hirnantian (Late Ordovician), Silurian, Carboniferous and Early Permian events. The sedimentary record associated with these glaciations, together with the intensity to which each has been investigated, is highly variable. As hydrocarbon exploration proceeds aggressively across the North Africa and Middle East regions, we review the relationship between glaciation and hydrocarbon accumulations. With the exception of Oman, and locally Egypt, which were tectonically active both during the Neoproterozoic and Early Palaeozoic all glaciations took place along an essentially stable passive continental margin. During the Neoproterozoic, two glaciations are recognised, referred to as older and younger Cryogenian glaciations respectively. Both of these Cryogenian events are preserved in Oman; only the younger Cryogenian has been reported in North Africa in Mauritania and Mali at the flanks of the Taoudenni Basin. The process of initial deglaciation in younger Cryogenian glaciations resulted in incision, at least locally producing large-bedrock palaeovalleys in Oman, and the deposition of glacial diamictites, gravels, sandstones and mudstones. As deglaciation progressed "cap carbonates" were deposited, passing vertically into shale with evidence for deposition in an anoxic environment. Hence, younger Cryogenian deglaciation may be associated with hydrocarbon source rock deposits. Hirnantian (Late Ordovician) glaciation was short lived (rock across the region. Existing models do not adequately explain the temporal and spatial development of anoxia, and hence of black shale/deglacial source rocks. The origins of a palaeotopography previously invoked as the primary driver for this anoxia is allied to a complex configuration of palaeo-ice stream pathways, "underfilled" tunnel valley incisions

    Full Text Available Background: Hydrocephalus among children is an important medical problem in view of its neurological sequelae in the growing child. This situation is compounded by the acute shortage of neurosurgeons in third world countries like Nigeria; hence, the need for its early detection and proper management. Objective: Evaluation of the ultrasound (US appearances in children under 5 years of age presenting with clinical signs of raised intracranial pressure suggestive of hydrocephalus. Patients and Methods: A retrospective review of transfontanelle US scans done in 64 children (39 boys and 25 girls attending the Department of Radiology, Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria over a period of 2 years was carried out. The patients had a mean age of 5.0 ± 4.6 months (range: 1–60 months at the time of their US examination. Some of the clinical indications for US scan included: Congenital hydrocephalus, encephalocele, meningomyelocele, and meningitis. All scans were performed through the anterior fontanelle using SIUI Apogee 800 PLUS scanner with a curvilinear probe using multi-frequency transducer of 2–5 MHz. Results: Fifty-two patients (81.3% had hydrocephalus of congenital origin. Eleven cases (17.2% had postmeningitic hydrocephalus while only 1 case (1.6% was posthemorrhagic. Twenty-five patients (48.0% of the congenital cases were due to cerebral aqueduct stenosis. Eleven (21.2% of the congenital cases were from obstruction at the exit foramina of Luschka and Magendie resulting in the communicating type of hydrocephalus. Conclusion: Hydrocephalus is a known cause of neurological morbidity among infants in developing countries. Majority of the cases are congenital in origin and most commonly due to cerebral aqueduct stenosis. Transfontanelle US is cheap, affordable, nonhazardous, and more accessible than other imaging modalities. It should serve as the first-line investigation of infants with suspected hydrocephalus for early

    Full Text Available Aluminum (Al is the third most abundant metal in earth crust, whose chemical form is mainly dependent on soil pH. The most toxic form of Al with respect to plants is Al3+, which exists in soil pH <5. Acidic soil significantly limits crop production mainly due to Al3+ toxicity worldwide, impacting approximately 50% of the world's arable land (in North-Eastern India 80% soil are acidic. Al3+ toxicity in plants ensues root growth inhibition leading to less nutrient and water uptake impacting crop productivity as a whole. Rice is one of the chief grains which constitutes the staple food of two-third of the world population including India and is not untouched by Al3+ toxicity. Al contamination is a critical constraint to plant production in agricultural soils of North East India. 24 indigenous Indica rice varieties (including Badshahbhog as tolerant check and Mashuri as sensitive check were screened for Al stress tolerance in hydroponic plant growth system. Results show marked difference in growth parameters (relative growth rate, Root tolerance index, fresh and dry weight of root of rice seedlings due to Al (100 μM toxicity. Al3+ uptake and lipid peroxidation level also increased concomitantly under Al treatment. Histochemical assay were also performed to elucidate uptake of aluminum, loss of membrane integrity and lipid peroxidation, which were found to be more in sensitive genotypes at higher Al concentration. This study revealed that aluminum toxicity is a serious harmful problem for rice crop productivity in acid soil. Based on various parameters studied it's concluded that Disang is a comparatively tolerant variety whereas Joymati a sensitive variety. Western blot hybridization further strengthened the claim, as it demonstrated more accumulation of Glutathione reductase (GR protein in Disang rice variety than Joymati under stressed condition. This study also observed that the emergence of lethal toxic symptoms occurs only after 48h

    Hydrogen isotopic composition of plant biomass provides crucial information about plant ecophysiology and local hydrology. Little is known about the apparent fractionation between hydrogen in source water and epicuticular leaf waxes of coniferous tree species that dominate the boreal forest ecosystem exposed to prolonged periods of sunlight during the growing season. In this study, single rope canopy access techniques were used to harvest needle and twig material from the upper, middle and lower crown of north and south facing branches of Pinus sylvestris within the subarctic forest of North East Finland. Samples were collected towards the beginning of the growing season in July and repeated in late September 2010. Leaf and twig waters were extracted cryogenically and analysed for D-enrichment. Individual n-alkanes are currently being quantified and analyzed for 13C/12C and D/H compositions. The molecular and isotopic data are supplemented by long-term in-situ cuvette photosynthetic assimilation measurements as well as relative humidity (RH), air temperature, precipitation and wind speed data collected by Helsinki University (SMEAR I). In addition RH, air temperature, wind speed and incoming solar radiation measurements were made at each individual sample point at the time of harvesting to quantify meteorological and microclimatological variation within individual trees. The outcome of this investigation will provide important insights into plant biochemistry and physiology of a crucial climate sensitive higher plant species subjected to continuous low light throughout the season. Furthermore, this work will expand our understanding of modern and palaeo-hydrology not only in northern Finland but also in other boreal forests around the world.

    The Middle East and North Africa (MENA) regional climate appears to be extremely sensitive to volcanic eruptions. Winter cooling after the 1991 Pinatubo eruption far exceeded the mean hemispheric temperature anomaly, even causing snowfall in Israel. To better understand MENA climate variability, the climate responses to the El Chichón and Pinatubo volcanic eruptions are analyzed using observations, NOAA/NCEP Climate Forecast System Reanalysis, and output from the Geophysical Fluid Dynamics Laboratory\\'s High-Resolution Atmospheric Model (HiRAM). A multiple regression analysis both for the observations and the model output is performed on seasonal summer and winter composites to separate out the contributions from climate trends, El Niño Southern Oscillation (ENSO), North Atlantic Oscillation (NAO), Indian summer monsoon and volcanic aerosols. Strong regional temperature and precipitation responses over the MENA region are found in both winter and summer. The model and the observations both show that a positive NAO amplifies the MENA volcanic winter cooling. In boreal summer, the patterns of changing temperature and precipitation suggest a weakening and southward shift of the Intertropical Convergence Zone, caused by volcanic surface cooling and weakening of the Indian and West African monsoons. The model captures the main features of the climate response; however, it underestimates the total cooling, especially in winter, and exhibits a different spatial pattern of the NAO climate response in MENA compared to the observations. The conducted analysis sheds light on the internal mechanisms of MENA climate variability and helps to selectively diagnose the model deficiencies.

    The local glaciers and ice caps of Greenland are becoming more apparent players in global sea-level rise, and their contribution to future changes is significant. Very little information on their historical fluctuations exists as much of the focus has been on the Greenland Ice Sheet. Now, we can for the first time present historic data that spans 110 years for more than 200 of the local glaciers and ice caps covering this large and important region of the Arctic. The central- and north eastern part of Greenland is of particular interest as these areas are predicted to exhibit a more active behavior with higher mass loss in the future - simultaneously with an increase in precipitation. Our results show that the glaciers and ice caps in the region are responding very rapidly to changes in temperature and precipitation. The present retreat is the fastest observed within the last eight decades, only surpassed by the rapid post LIA retreat. The 1930s was the golden era for scientific exploration in Central- and North East Greenland as several large expeditions visited the area and photographed from land, sea and air. We use historic recordings from Danish and Norwegian aerial missions and terrestrial recordings from the renowned American Explorer Louise Boyd. These unique pictures from the early 1930s form the backbone of the study and are supplemented the more recent aerial photographs the 1940s and onwards and satellite imagery from the mid-1960s and up until present. From high resolution aerial photographs we are able to map the maximum extent of the glaciers during the LIA (Little Ice Age), from which retreat in this area is estimated to commence in 1900. Using a new SMB (Surface Mass Balance) model and its components covering the entire observational period along with high resolution DEMs and historic sea-ice records we are now able to extract valuable information on the past and present triggers of glacial change.

    The Middle East and North Africa (MENA) region is the world's most water-stressed region, with its countries constituting 12 of the 15 most water-stressed countries globally. Because of data paucity, comprehensive regional-scale assessments of groundwater resources in the MENA region have been lacking. The presented study addresses this issue by using a distributed ArcGIS model, parametrized with gridded data sets, to estimate groundwater storage reserves in the region based on generated aquifer saturated thickness and effective porosity estimates. Furthermore, monthly gravimetric datasets (GRACE) and land surface parameters (GLDAS) were used to quantify changes in groundwater storage between 2003 and 2014. Total groundwater reserves in the region were estimated at 1.28 × 106 cubic kilometers (km3) with an uncertainty range between 816,000 and 1.93 × 106 km3. Most of the reserves are located within large sedimentary basins in North Africa and the Arabian Peninsula, with Algeria, Libya, Egypt, and Saudi Arabia accounting for approximately 75% of the region's total freshwater reserves. Alternatively, small groundwater reserves were found in fractured Precambrian basement exposures. As for groundwater changes between 2003 and 2014, all MENA countries except for Morocco exhibited declines in groundwater storage. However, given the region's large groundwater reserves, groundwater changes between 2003 and 2014 are minimal and represent no immediate short-term threat to the MENA region, with some exceptions. Notwithstanding this, the study recommends the development of sustainable and efficient groundwater management policies to optimally utilize the region's groundwater resources, especially in the face of climate change, demographic expansion, and socio-economic development.

    Full Text Available Abstract Background Although numerous studies on parasites of the Atlantic cod, Gadus morhua L. have been conducted in the North Atlantic, comparative analyses on local cod parasite faunas are virtually lacking. The present study is based on examination of large samples of cod from six geographical areas of the North East Atlantic which yielded abundant baseline data on parasite distribution and abundance. Materials and Methods A total of 826 fish was sampled in the Baltic, Celtic, Irish and North seas, Icelandic waters and Trondheimsfjord (Norway in 2002 (spring and autumn and 2003 (spring. The gills and internal organs (oesophagus, stomach, intestine, pyloric caeca, liver, heart, spleen, gall bladder and gonads were examined for macroparasites following a standardised protocol. The taxonomic consistency of the identification was ensured thorough the entire study. Results We discuss some problems in parasite identification, outline the composition of the parasite faunas in cod in the six North East Atlantic regions, provide novel data on parasite prevalence and abundance and a comparative assessment of the structure of the regional parasite faunas with respect to the higher-level taxonomic groupings, host specificity and zoogeographical distribution of the parasites. Altogether 57 different parasite forms were found including seven new host records (Diclidophora merlangi, Rhipidocotyle sp., Fellodistomum sp., Steringotrema sp., Cucullanus sp., Spinitectus sp., and Chondracanthus ornatus. The predominant groups of cod parasites were trematodes (19 species and nematodes (13 species including larval anisakids which comprised 58.2% of the total number of individuals. Conclusion Our study reveals relatively rich regional parasite faunas in cod from the North East Atlantic which are dominated by generalist parasites with Arcto-Boreal distribution. Further, it provides more detailed data on the distribution in the North East Atlantic of the majority

Issues related to provision, cost, and acceptability may affect the use of IPTp in some developing countries. The aim of the study was to assess the uptake and adherence to sulphadoxine-pyrimethamine-based intermittent preventive treatment of malaria during pregnancy and the relationship of IPTp use to pregnancy outcomes in two major obstetric centers in South East Nigeria. Methods: This was a prospective descriptive study involving women who received antenatal and delivery services. All recruited women were followed-up from booking until delivery, and statistical analysis was done with Epi Info version 7. Results: A total of 516 parturients were studied. The mean gestational age at booking was 21.8±6.9 weeks while the mean number of antenatal visits throughout the pregnancy was 5.5±3.1. The rate of uptake of at least one dose of prescribed IPTp was 72.1% (367/516. Of the 367 who took prescribed IPTp, adherence to second doses of IPTp was 59.7% (219/367, and only 4.9% (18/367 took a third dose. Clinical malaria occurred in 85% (127/149 of women who did not receive IPTp at all compared to 20.5% of those who received at least one dose of IPTp. All those who had clinical malaria despite IPTp had only one

    We have tested the regional climate sensitivity in the Middle East and North Africa (MENA) to radiation perturbations caused by the large explosive equatorial volcanic eruptions of the second part of 20th century, El Chichon and Pinatubo occurred, respectively, in 1982 and 1991. The observations and reanalysis data show that the surface volcanic cooling in the MENA region is two-three times larger than the global mean response to volcanic forcing. The Red Sea surface temperature appears to be also very sensitive to the external radiative impact. E.g., the sea surface cooling, associated with the 1991 Pinatubo eruption, caused deep water mixing and coral bleaching for a few years. To better quantify these effects we use the Geophysical Fluid Dynamics Laboratory global High Resolution Atmospheric Model (HIRAM) to conduct simulations of both the El Chichon and Pinatubo impacts with the effectively 25-km grid spacing. We find that the circulation changes associated with the positive phase of the arctic oscillation amplified the winter temperature anomalies in 1982-1984 and 1991-1993. The dynamic response to volcanic cooling also is characterized by the southward shift of the inter-tropical convergence zone in summer and associated impact on the precipitation patterns. Thus, these results suggest that the climate regime in the MENA region is highly sensitive to external forcing. This is important for better understanding of the climate variability and change in this region.

    Full Text Available In their day-to-day practice, pharmacists, graduate (pre-registration pharmacists, pharmacy technicians, dispensing assistants and medicines counter assistants use widely available office, retail and management information systems alongside dedicated pharmacy management and electronic health (ehealth applications. The ability of pharmacy staff to use these applications at home and at work, also known as digital literacy or digital competence or e-skills, depends on personal experience and related education and training. The aim of this research was to gain insight into the self-reported digital literacy of the pharmacy workforce in the North East of Scotland. A purposive case sample survey was conducted across NHS Grampian in the NE of Scotland. Data collection was based on five items: sex, age band, role, pharmacy experience plus a final question about self-reported digital literacy. The study was conducted between August 2012 and March 2013 in 17 community and two hospital pharmacies. With few exceptions, pharmacy staff perceived their own digital literacy to be at a basic level. Secondary outcome measures of role, age, gender and work experience were not found to be clear determinants of digital literacy. Pharmacy staff need to be more digitally literate to harness technologies in pharmacy practice more effectively and efficiently.

    The presence of toxic metals in milk may create significant health problems for the population. In this study, 1440 raw cow and ewe milk samples from 18 townships in north-east Iran were analysed in four different seasons. Lead, cadmium and mercury levels were determined using atomic absorption spectrophotometry. Mean concentration of lead, cadmium and mercury in cow milk samples was 12.9 ± 6.0, 0.3 ± 0.3 and 3.1 ± 0.3 ng g⁻¹, respectively, and in ewe milk samples, these mean values were 14.9 ± 7.8, 1.6 ± 1.2 and 3.1 ± 0.3 ng g⁻¹, respectively. Statistical analyses showed that lead and cadmium concentrations in ewe milk were significantly higher than in cow milk. Concentrations of these metals in ewe milk varied significantly with different seasons. As the concentrations did not exceed the safety limits, they could not pose a serious danger to public health.

    The present investigation has been conducted to delineate the hydrogeochemical and environmental factors that control the water quality of the groundwater resources in the north-east of Cairo. A complementary approach based on hydrogeochemistry and a geographical information system (GIS) based protectability index has been employed for conducting this work. The results from the chemical analysis revealed that the groundwater of the Quaternary aquifer is less saline than that of the Miocene aquifer and the main factors that control the groundwater salinity in the studied area are primarily related to the genesis of the original recharging water modified after by leaching, dissolution, cation exchange, and fertilizer leachate. The computed groundwater quality index (WQI) falls into two categories: fair for almost all the Miocene groundwater samples, while the Quaternary groundwater samples are all have a good quality. The retarded flow and non-replenishment of the Miocene aquifer compared to the renewable active recharge of the Quaternary aquifer can explain this variation of WQI. The index and overlay approach exemplified by the DUPIT index has been used to investigate the protectability of the study aquifers against diffuse pollutants. Three categories (highly protectable less vulnerable, moderately protectable moderately vulnerable and less protectable highly vulnerable) have been determined and areally mapped.

    Propolis is a bee product with wide diversity of biological activity. It has a complex composition, which is dependent on its botanical source. The present study aimed to determine the chemical profile, antioxidant activity and botanical origin of two samples of a propolis type from two locations of the state of Rio Grande do Norte (RN, north-east Brazil). The standard chemical characteristics of the RN propolis are similar or superior to the internationally marketed Brazilian green propolis. RN propolis from two locations have high antioxidant activity, corresponding to 10% (municipality of Afonso Bezerra) and 13% (municipality of Alto do Rodrigues) of quercetin activity by the 2,2-diphenyl-1-picrylhydrazyl method and to 15% (both locations) by the β-carotene discoloration method. High-performance liquid chromatography with diode array detection (HPLC-DAD)-electrospray ionization-tandem mass spectrometry analyses revealed that most constituents of the RN propolis are flavonoids, mainly flavonols and chalcones. HPLC-DAD analysis of ethanol extracts revealed a great similarity between the chemical profile of RN propolis and shoot apices of 'jurema-preta' (Mimosa tenuiflora, Leguminosae, Mimosoideae). 'Jurema-preta' shoot apices are likely resin sources of RN propolis. The chemical characteristics and antioxidant property of RN propolis provide promising prospects for the introduction of this type of propolis into the apicultural market. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    In 1994 there were substantial increases in the quantity of 99 Tc discharged into the north-east Irish Sea from BNFL Sellafield (UK), concomitant with improvements in waste treatment procedures. As a consequence, the concentration of 99 Tc observed in seawater and biota samples, taken from the Irish Sea coastline, increased significantly. Elevated concentrations were also reported in Dutch, Danish, Norwegian, Swedish and Arctic waters in subsequent years. In the present study a simple numerical model was developed and applied to time-series data of 99 Tc concentrations in the brown seaweed Fucus vesiculosus, collected from three UK sites in the vicinity of Sellafield (St. Bees, Heysham, Port William). The model considered site-specific scaling effects, lag times, previous discharge history and potential seasonal variation in uptake. In general, there was a good fit between predicted and observed concentrations, but the degree of uncertainty varied inversely with the frequency of sampling. We did not observe a significant seasonal variation. The modelled lag times to the three sites were consistent with transport times based on observations of the water column distribution of 99 Tc. The model was applied to a variety of discharge scenarios, reflecting current discussion on the future management of 99 Tc releases. Concentrations in Fucus reached asymptotic values in 3-10 years, depending on the scenario and sampling site under consideration

    In the diverse relief of north-east part of Kosova a relatively wide range occupies the relief modelled by the descent phenomenon, which is conditioned by morph-structural and climatic factors quite suitable for their development. The morphogenesis activity of descent phenomenon is conditioned by the types of rocks, tectonic process of this region and climatic conditions. These factors condition horizontal and vertical relief fragmentation, slope, especially in Gollaku mountains and in SE part of Kopaonik mountain. Along the tectonic descents, the steepness is detaching and the detaching lines consisting of magmatic rocks show overthrows, demolitions and stony torrents, but the Teri gene composition formations are modelled by sliding and muddy torrents, depending upon the presence of clayey and alevrolite belts on these Teri gene ones. The impact of factors and conditions on the relief of this part, the phenomena like demolitions, overthrows, sliding, muddy torrents, stony torrents, etc, operate here, which play an important morphological role in the modelling of relief.

    The city of Santander ceased the discharge of sewage effluents into the bay of Santander in June, 2001 and began discharging at a site 2.4 km offshore in the nearby coastal area (Virgen del Mar, Bay of Biscay) at a water depth of about 40 m. The present study investigates the effects of the new outfall discharges on the water quality of the high-energy coastal area and the recovery of the perturbed temperate estuarine area now only affected by combined sewer overflows (CSOs). Nutrients, phytoplankton biomass and urban pollution indicators were analysed. No significant spatial or temporal change in water quality variables was found in the coastal area around the outfall. No signs of nutrification or increases in chlorophyll-a were observed throughout the study period, although a slight increase in phosphates, suspended solids and turbidity were observed two years after the relocation of the discharge. These changes were not attributed to outfall discharge but to a regional increase also observed at control stations and nearby coastal areas. Considerable reductions in indicators of urban discharges were observed in the estuary after the relocation of discharges, even at stations located around CSOs. Results from this study support the efficiency of ecological quality-driven designs of sanitation systems, which are used as management tools for sensitive and environmentally valuable coastal ecosystems in the north-east Atlantic.

    The energy landscape of the Middle East and North Africa (MENA) region has undergone a significant transformation in recent years as a result of intersecting technological, economic and political trends, both regional and international. The evolving dynamics of international energy markets, increased diversification of energy sources, global concerns for climate change, and regional conflict are among the leading factors impacting the evolution of MENA energy policy. This paper provides an assessment and outlook for energy policy in the MENA region within the context of the myriad factors impacting policy design and implementation. A review and analysis of the social, political and economic factors that are impacting regional energy policy is provided and followed by analysis of regional energy policy with consideration of hydrocarbon exploration and production, regional energy trade, demand management and clean energy production. The findings show that the MENA region is in the midst of an energy transition that has uncertain outcomes but will undoubtedly have long lasting impacts on the global energy system. - Highlights: • The MENA region is undergoing an energy transition shaped by political, social and economic dynamics. • Political, economic and social turmoil will constrain energy systems developments in many MENA countries. • MENA countries that can evolve their energy systems are prioritizing energy security and energy cost minimization. • Energy demand management, sustainable energy supply and regional cooperation are essential to achieving energy priorities.

    Full Text Available Women entrepreneurship benefit from a process of expansion all over the world. Business established and developed by women are an important source of wealth and improved living standards in many countries. Even though women represent 46% of Europe's working population, which means in theory that trend of this type entrepreneurship can only go upward, however entrepreneurship is still considered an activity for men. Entrepreneurship has an active role in employment, economic development and quality of life, constituting a dynamic part of any developed economy. Supporting women in their involvement in setting up new start-ups and small business and unlock their potential is an important part of government actions to foster entrepreneurial activities. Global Entrepreneurship Monitor (GEM study found out that economies of Eastern European countries are in poor condition in terms of women's participation in entrepreneurial activity. Romania is no exception. This paper analyze women entrepreneurship in the poorest region of Romania, North East region, through an empirical survey but provide also some insights on overall Romanian situation based on National Trade Register Office data.

    A regional workshop on sexual and bodily rights as human rights in the Middle East and North Africa was held in Malta in 2003, attended by 22 NGO representatives from Jordan, Egypt, Lebanon, Palestine, Tunisia, Morocco, Algeria, Turkey, Pakistan and USA. The meeting aimed to develop strategies for overcoming human rights violations in the region with reference to law and social and political practices. Session topics included sexuality and gender identity; sexuality and sexual health; sexuality and comparative penal law; sexual rights in international documents; advocacy and lobbying. Sexual rights, sexual health and education, sexual violence and adolescent sexuality were explored in depth, including taboos and emerging trends. Specific areas of concern included marital rape, early marriages, temporary marriages, sexual orientation, premarital and extramarital sexuality, honour crimes, female genital mutilation, unmarried mothers, adolescent sexuality, unwanted pregnancies and safe abortion, sexuality in education and health services. An analysis of civil codes, penal codes and personal status codes indicated a clear imperative for legal reform. Participants heard about efforts to promote the right to sexual orientation which have already been initiated in Lebanon, Turkey and Tunisia. Networking within the region and with counterparts in other regions in comparable situations and conditions was deemed essential.

    Full Text Available All Parties to the United Nations Framework Convention on Climate Change (UNFCCC were requested to communicate intended nationally determined contributions (INDCs in a clear, transparent and understandable way before the Conference of the Parties (known as COP21 held in Paris in 2015. The Contributions were supposed to be balanced and comprehensive to ensure sustainable development and expected to include finance, technology requires, technology transfer and capacity building aiming at mitigation and adaptation. This research focuses on investigating the INDCs prepared by countries from the Middle East and North Africa (MENA, one of the most water-scarce and dry regions in the world. Following a content analysis, this research has found that INDCs from the region have not been able to reflect the desired output. Submissions were also not timely and not sufficiently ahead of time. Many countries were not able to disclose the current status. INDCs can play a significant role by providing objective, timely, and reliable information, which is missing at present in the countries from MENA.

    Major element chemistry, rare-earth element distribution, and H and O isotopes are conjointly used to study the sources of salinisation and interaquifer flow of saline groundwater in the North East German Basin. Chemical analyses from hydrocarbon exploration campaigns showed evidence of the existence of two different groups of brines: halite and halite Ca-Cl brines. Residual brines and leachates are identified by Br-/Cl- ratios. Most of the brines are dissolution brines of Permian evaporites. New analyses show that the pattern of rare-earth elements and yttrium (REY) are closely linked to H and O isotope distribution. Thermal brines from deep wells and artesian wells indicate isotopically evaporated brines, which chemically interacted with their aquifer environment. Isotopes and rare-earth element patterns prove that cross flow exists, especially in the post-Rupelian aquifer. However, even at depths exceeding 2,000 m, interaquifer flow takes place. The rare-earth element pattern and H and O isotopes identify locally ascending brines. A large-scale lateral groundwater flow has to be assumed because all pre-Rupelian aquifer systems to a depth of at least 500 m are isotopically characterised by Recent or Pleistocene recharge conditions.

    Full Text Available Diversity, relative abundance and dominance of phytoplankton community of the Lake Baskandi anua, an oxbow lake of Assam, North east India were studied during December 2009 to November 2010. Chlorophyll content and biomass of phytoplankton along with physico-chemical properties of water of the lake were also estimated. The lake is covered with Hydrilla and other macrophytes like Eichhornia, Trapa, Altrnenthera, Polygonum, Ludwizia sp., etc. Seasonal fluctuations of 41 genera of phytoplankton, belonging to 5 groups (Chlorophyceae, Cyanobacteria, Bacillariophyceae, Euglenophyceae and Dinophyceae were encountered in the lake. Chlorophyceae was found to be highest in winter, Cyanobacteria and Euglena in monsoon and Bacillariophyceae in pre monsoon. According to Engelmann’s scale, Spirogyra indica was found eudominant followed by 10 dominant, 24 subdominant and 20 recedent species. Chlorophyll- a content of phytoplankton varied from 14.18 to 33.89 μg·L-1, during the study period. One way analysis of variance (ANOVA revealed significant seasonal variation in physico-chemical properties of water like Water temperature, pH, Conductivity, Dissolved oxygen, Free CO2, Total alkalinity, Calcium, Chloride, Nitrate and Ammonia. Relationship between phytoplankton group assemblage and environmental variables were explored by the ordination method CCA (Canonical Correspondence Analysis.

    Full Text Available Phytoplankton diversity was investigated over a period of two years (2006 to 2008 in Chatla floodplain wetland in Barak valley, Assam, North-East India. Site 1 and site 2 are two inlets and site 3 is a lentic system associated with vegetation cover of Calamus tenuis and Baringtonia acutangula. The floodplain has a unique hydrology because of the presence of different types of habitats (inlets, fisheries, beels and outlets which maintains a network among the floodplains, rivers and streams. Phytoplankton community composition, density and diversity were studied in relation to environmental variables. All the variables were estimated by following standard methods. Phytoplankton was collected by plankton net and quantitative estimation was made by using Sedgwick Rafter counting cell. Phytoplankton community comprised 53 taxa represented by Chlorophyceae (31, Cyanophyceae (11, Bacillariophyceae (7, Euglenophyceae (1 and Dinophyceae (3. Phytoplankton taxa was dominated by Volvox sp., Nostoc sp., Eunotia sp., Navicula sp., Euglena spp. and density was found highest in site 3 and lowest in site 1. Shannon diversity index (H′ for phytoplankton community varied between 2.4 to 2.65 indicating fairly high species diversity. The varying magnitude of correlationship among environmental variables and phytoplankton species density as shown by Canonical correspondence analysis (CCA indicated that some of the environmental variables (water temperature, transparency, rainfall, nitrate and ammonia are the driving factors for governing the phytoplankton species assemblages in Chatla floodplain wetland. Fluctuation of phytoplankton density and community composition in different habitats indicated various niche apportionment as well as anthropogenic influences.

    Full Text Available Introduction: Moyamoya disease is a chronic progressive cerebrovascular disorder, characterized by stenosis or occlusion of bilateral internal carotid arteries (ICAs, anterior cerebral arteries (ACAs and middle cerebral arteries (MCAs, accompanied by a collateral network of vessels formed at the base of the brain. Ischemia and intracranial hemorrhage are the common typical manifestations. However moyamoya disease has been associated with atypical presentations like headache, seizures and involuntary movements. Although frequently reported from Asian countries like Japan, China and Korea, only few studies reported on clinical manifestations of moyamoya disease from India. Objectives: To study the varied presentations of moyamoya disease in a tertiary care hospital of north-east India. Material and Methods: Relevant investigations were done to rule out other causes of moyamoya syndrome. Results: We report 6 cases of moyamoya disease with varied presentations from a tertiary care referral government hospital. Case 1, 2 and 6 presented with alternating hemiparesis. Case 3 had amaurosis fugax. Case 4 had history suggestive of ischemic stroke and presented with hemichorea. Case 4 had focal seizure as the only manifestation. Cases 4 and 5 notably had stenosis of posterior cerebral artery (PCA in addition to stenosis of bilateral ICAs, ACAs and MCAs. Conclusion: Owing to its low incidence in India, moyamoya disease is easily overlooked as a possible diagnosis. However, because of its progressive nature, it is imperative to diagnose this disease early and offer surgical treatment to the patients.

    Brain tumors are a mixed group of neoplasms that originate from the intracranial tissues and the meninges with degrees of malignancy varying greatly from benign to aggressive. Not much is known about the epidemiology of primary malignant brain tumors (PMBTs) in our population in North-East India. In this analysis, an attempt was made to identify the age groups, gender distribution, topography and different histological types of PMBT with data from a hospital cancer registry. A total of 231 cases of PMBT were identified and included for the present analysis. Our analysis has shown that most of PMBT occur at 20-60 years of age, with a male to female ratio of 2.3:1. Some 70.5% of cases occurred in cerebral lobes except for the occipital lobe, and astrocytic tumors were the most common broad histological type. In our population the prevalence of PMBT is 1% of all cancers, mostly affecting young and middle aged patients. As brain tumors are rare, so case-control analytic epidemiological studies will be required to establish the risk factors prevalent in our population.

    In their day-to-day practice, pharmacists, graduate (pre-registration) pharmacists, pharmacy technicians, dispensing assistants and medicines counter assistants use widely available office, retail and management information systems alongside dedicated pharmacy management and electronic health (ehealth) applications. The ability of pharmacy staff to use these applications at home and at work, also known as digital literacy or digital competence or e-skills, depends on personal experience and related education and training. The aim of this research was to gain insight into the self-reported digital literacy of the pharmacy workforce in the North East of Scotland. A purposive case sample survey was conducted across NHS Grampian in the NE of Scotland. Data collection was based on five items: sex, age band, role, pharmacy experience plus a final question about self-reported digital literacy. The study was conducted between August 2012 and March 2013 in 17 community and two hospital pharmacies. With few exceptions, pharmacy staff perceived their own digital literacy to be at a basic level. Secondary outcome measures of role, age, gender and work experience were not found to be clear determinants of digital literacy. Pharmacy staff need to be more digitally literate to harness technologies in pharmacy practice more effectively and efficiently.

    Full Text Available The prevalence of stunting (low height-for-age is a key indicator of long-term chronic undernutrition which reflects an anthropometric failure to reach linear growth potentials due to prolonged food deprivation and/or disease or illness during the early stage of life. The present study assesses the prevalence and socio-economic and demographic correlates of stunting among adolescents of the North-east India. This cross-sectional study was undertaken among 1,818 (830 boys; 988 girls adolescents (aged 10-18 years belonging to ethnically heterogeneous populations of Karbi Anglong district of Assam, using stratified random sampling method. Anthropometric measurements of height and weight were recorded using standard procedures. Socio-economic and demographic variables were obtained using pre-structured schedule. The age-sex specific L, M and S reference values were used to calculate height-for-age Z-score (HAZ. According to WHO, HAZ found to be 0.05. The binary logistic regression analysis showed that several socio-economic and demographic variables were significantly associated with stunting (p<0.05. The step-wise multiple logistic regression analysis showed that sex (boys, age groups (13-15 years and 16-18 years, father’s occupation (cultivator and Rupees ≤5000 household income was significantly associated with stunting (p<0.05. Appropriate nutritional intervention programmes and dissemination of knowledge at population level related to undernutrition are necessary to ameliorate their nutritional status.

    2015-01-01

    The effect of different factors (spawning biomass, environmental conditions) on recruitment is a subject of great importance in the management of fisheries, recovery plans and scenario exploration. In this study, recently proposed supervised classification techniques, tested by the machine-learning community, are applied to forecast the recruitment of seven fish species of North East Atlantic (anchovy, sardine, mackerel, horse mackerel, hake, blue whiting and albacore), using spawning, environmental and climatic data. In addition, the use of the probabilistic flexible naive Bayes classifier (FNBC) is proposed as modelling approach in order to reduce uncertainty for fisheries management purposes. Those improvements aim is to improve probability estimations of each possible outcome (low, medium and high recruitment) based in kernel density estimation, which is crucial for informed management decision making with high uncertainty. Finally, a comparison between goodness-of-fit and generalization power is provided, in order to assess the reliability of the final forecasting models. It is found that in most cases the proposed methodology provides useful information for management whereas the case of horse mackerel is an example of the limitations of the approach. The proposed improvements allow for a better probabilistic estimation of the different scenarios, i.e. to reduce the uncertainty in the provided forecasts.

    The paper presents a strategy for the market introduction of concentrating solar power (CSP) plants in the Middle East and North Africa (MENA) that will not require considerable subsidization and will not constitute a significant burden for electricity consumers in the region. In the first section, the paper explains the need of MENA countries for sustainable supply of electricity and calculates the cost of electricity for a model case country. In the second part, the cost development of concentrating solar power plants is calculated on the basis of expectations for the expansion of CSP on a global level. After that, the challenges for the market introduction of CSP in MENA are explained. Finally, we present a strategy for the market introduction of CSP in MENA, removing the main barriers for financing and starting market introduction in the peak load and the medium load segment of power supply. The paper explains why long-term power purchase agreements (PPA) for CSP should be calculated on the basis of avoided costs, starting in the peak load segment. Such PPA are not yet available, the paper aims to convince policy makers to introduce them. (author)

    2007-05-01

    This paper provides an overview of legal, religious, medical and social factors that serve to support or hinder women's access to safe abortion services in the 21 predominantly Muslim countries of the Middle East and North Africa (MENA) region, where one in ten pregnancies ends in abortion. Reform efforts, including progressive interpretations of Islam, have resulted in laws allowing for early abortion on request in two countries; six others permit abortion on health grounds and three more also allow abortion in cases of rape or fetal impairment. However, medical and social factors limit access to safe abortion services in all but Turkey and Tunisia. To address this situation, efforts are increasing in a few countries to introduce post-abortion care, document the magnitude of unsafe abortion and understand women's experience of unplanned pregnancy. Religious fatāwa have been issued allowing abortions in certain circumstances. An understanding of variations in Muslim beliefs and practices, and the interplay between politics, religion, history and reproductive rights is key to understanding abortion in different Muslim societies. More needs to be done to build on efforts to increase women's rights, engage community leaders, support progressive religious leaders and government officials and promote advocacy among health professionals.

    The present study describes prevalence of peste des petits ruminants (PPR) virus infection in goats in various parts of North-East (NE) India by screening of suspected serum samples collected during outbreak investigation and random samples during 2013-2014 survey. A total of 391 serum samples (318 random and 73 outbreak/suspected) were collected from 28 districts in 7 states (Meghalaya, Assam, Manipur, Nagaland, Arunachal Pradesh, Tripura and Mizoram) of NE India. Serum samples were screened for PPRV-specific antibodies by using PPR monoclonal-antibody based competitive ELISA. Analysis of 391 serum samples indicates that an overall seroprevalence of 17.90 % [CI 95 % 14.40-22.00] in goats {45.2 % in suspected [CI 95 % 34.32-56.58] and 11.63 % in random [CI 95 % 8.56-15.63] samples} in NE India. As expected prevalence was high in outbreaks vis-à-vis random samples. The random survey results (11.63 %) has specific implication in epidemiological perspectives, since it highlights the exact PPR prevalence under natural situations, where the subclinical, in apparent or nonlethal or recovery of infection was suspected in goats, as samples were collected from unvaccinated animals. It also warrants appropriate control measures against PPR in NE region to prevent spread of infection besides widespread presence of the disease in rest of India.

    High energy demand has necessitated search for all possible sources of energy. Conventional energy source is having negative impact on our environment, therefore our attention is focused on renewable energy sources, such as solar, wind, hydro, which are considered to be clean and sustainable energy sources. India has set an ambitious target of producing 175 GW of energy using solar energy. Therefore, it is necessary to estimate the solar potential to observe the feasibility of such project. North-east India is an underdeveloped region of India and due to its geographical location and difficult terrain, many regions are still not electrified. Such regions can be electrified by installing renewable energy based power plants, which can also generate number of jobs hence improving the quality of life and economic condition of the region. The objective of this paper is to estimate the solar power potential of Silchar (Assam, India) and perform a feasibility study for installation of solar-based power plant in the region. In this paper, solar radiation on tilted surface is estimated by using an anisotropic sky model. This radiation data has been used to estimate the PV power output. Finally, feasibility of the PV plant has been verified by mapping with a practical load demand.

    Petroleum is not purely an economical product, its main role in world economy and its concentration in Middle East and North Africa (two third of world reserves) made influence international politics. Knowing the nature of the region, petroleum and politics make one. The politicization of oil in the region starts, first of all, with the efforts of some powers, through their companies, to dominate oil countries, which by reaction incite these countries to eliminate foreign domination and establish their national control on oil matters. The situation is changing progressively. The position of productive states got stronger with the beginning of the 1970's which permitted the use of oil, in a way relatively efficient, as an instrument of power. Consequently, the balance of power shifted deeply in the favor of producers. On this basis, the argument consists of three parts: the first puts theoretic bases - theory of economical arm - and defines geographical and historical environment of the research. The second part studies the period of force of the oil countries, from the fourth Israel-Arab war and oil embargo that followed it, to the end of the second oil slump. The third part explains the shift of power on the international scene and the relative decline of oil power for the states of the region. The analysis of impact of the oil slump in 1986 and the mini impact of the second Persian Gulf war, quickly dominated, lead to clear the actual situation and outline the viewpoint of the future.

    The oxygen minimum zone (OMZ) of the tropical North East Atlantic (TNEA) is located between the oxygen-rich equatorial region and the Cape Verde Frontal Zone at about 20°N in a depth range of 300 - 700 m. Its horizontal extent is predominantly defined by the North Equatorial Current and by the equatorial zonal current system ventilating the region to the north and south of the OMZ, respectively. The interior of the OMZ is characterized by a sluggish flow regime, where mesoscale eddies play a major role in the ventilation. In this study we focus on the oxygen variability in the TNEA as well as the eddy driven lateral ventilation of the TNEA OMZ across its southern boundary. During recent years an intense measurement program was executed along 23°W cutting meridionally through the TNEA OMZ. Hydrographic and velocity data has been acquired from ship sections and moorings, together covering the latitude range between 6°S and 14°N with particularly high meridional resolution of shipboard and high temporal resolution of moored observations. Based on shipboard data we derived a meridional section of oxygen variance, which reveals numerous local maxima of oxygen variability. Exemplary, strong oxygen variability is observed at the upper (300m, 5° - 12°N) and the southern boundary (400m - 700m, 5°N - 8°N) of the OMZ, whereas the interior of the OMZ is characterized by weak variability. An application of the extended Osborn-Cox model shows that the strong oxygen variability at the southern boundary is mainly generated by mesoscale eddies. The strong variability at the upper boundary is generated by mesoscale eddies as well as microscale turbulence. We apply two methods to estimate the meridional oxygen flux: 1) a flux gradient parameterization and 2) a correlation of oxygen and velocity mooring time series. From the analysis of the 5°N mooring data we find a northward oxygen flux directed towards the OMZ at its core depth, that is mainly due to variability of

    North China Craton is one of the best natural laboratories that research some Earth Dynamic questions[1]. Scientists made much progress in research on this area, and got vast geochemistry data, which are essential for answering many fundamental questions about the age, composition, structure, and evolution of the East China area. But the geochemical data have long been accessible only through the scientific literature and theses where they have been widely dispersed, making it difficult for the broad Geosciences community to find, access and efficiently use the full range of available data[2]. How to effectively store, manage, share and reuse the existing geochemical data in the North China Craton area? East-China Geochemistry Database(ECGD) is a networking geochemical scientific database system that has been designed based on WebGIS and relational database for the structured storage and retrieval of geochemical data and geological map information. It is integrated the functions of data retrieval, spatial visualization and online analysis. ECGD focus on three areas: 1.Storage and retrieval of geochemical data and geological map information. Research on the characters of geochemical data, including its composing and connecting of each other, we designed a relational database, which based on geochemical relational data model, to store a variety of geological sample information such as sampling locality, age, sample characteristics, reference, major elements, rare earth elements, trace elements and isotope system et al. And a web-based user-friendly interface is provided for constructing queries. 2.Data view. ECGD is committed to online data visualization by different ways, especially to view data in digital map with dynamic way. Because ECGD was integrated WebGIS technology, the query results can be mapped on digital map, which can be zoomed, translation and dot selection. Besides of view and output query results data by html, txt or xls formats, researchers also can

    The Veneto Volcanic Province (VVP), in the North-East of Italy represents one of the most important magmatic province of the Adria Plate. VVP magmatism occurred in a period ranging from late Paleocene to late Oligocene (De Vecchi et al., 1976). Five main volcanic districts can be defined from north-west to south-east: Val d'Adige, Marosticano, Lessini Hills, Berici Hills and Euganean Hills. Most of the volcanic products are relatively undifferentiated lavas, ranging in compostion from mela-nephelinites to quartz-normative tholeiites (Beccaluva et al., 2007). By contrast in the Euganean Hills volcanic and subvolcanic rocks range from subordinate basalts to prevalently acidic types, mostly quartz-trachytes and rhyolites (Milani et al., 1999). Despite of the deep petrological knowledge about this province, the radioisotopic ages of the related volcanic activities for each district are still poorly defined or even totally missing. 40Ar/39Ar ages on 9 samples have been obtained to determine the age range for the VVP. 40Ar/39Ar whole rock step heating analyses yielded ages ranging from 40.7 ± 0.2 Ma to 23.3 ± 1.5 Ma for basanites of Val d'Adige and Marosticano area, respectively. For the Lessinean district, 40Ar/39Ar whole rock analyses for two basanites, one trachybasalt and one alkali basalt close to 40 Ma, while a tholeiite from the same area yielded the youngest age for this district (i.e. 32.9 ± 1.8 Ma). This young age is comparable to 40Ar/39Ar ages obtained for the Euganean Hills intermediate-acidic rocks (Jourdan, pers. comm., 2016), suggesting a time-related shift from more alkaline to Si-saturated magmatism in the whole province.

    Full Text Available Abstract This study investigated the effect of incompetence in Arabic language on students’ performances in Islamic studies in the selected senior secondary schools in Ibadan South-East Local Government Area of Oyo State, Nigeria. The main objective of this study was to ascertain the argument that the poor performance of senior secondary students in Islamic studies is as a result of incompetence and non-proficiency in Arabic language on the side of learners and teachers. The methodology employed in this study was the quantitative approach. Location of the study was Ibadan South-East Local Government Area of Oyo State. Teachers of Islamic studies and students were randomly selected using the stratified random sampling technique from six senior secondary schools. The data gathered were analysed using simple percentages and chi-square statistical analysis. The findings revealed that significant number of students in Senior Secondary School’s poor performance in Islamic studies was due to their incompetence in Arabic as a result of their lack of exposure to the Arabic language and their poor background in Arabic from the previous classes. It also revealed that some of their teachers in Islamic studies were not competent in Arabic reading and writing.

    Marriage is a central stage in the transition to adulthood in the Middle East and North Africa (MENA). This paper builds on the existing literature on the effect of marriage on women’s employment in MENA. Besides examining how different types of work are affected by early marriage (defined as marriage by the median age of marriage) in a multivariate setting, the contribution of this paper is to endogenize the marriage decision using an instrumental variable approach. We find that marriage by ...

    Full Text Available The headways, spacing distributions and gap acceptance were measured from two main intersections in Minna, Central Nigeria/The average critical gap and spacing for stadium junction are 2.39 seconds and 11.08m respectively, and that of Mustapha hospital junction are 2.28 seconds and 9.56m respectively. The gap size at the intersections ranges between 1 and 57 seconds. Drivers accept gaps ranging from 2.89 to 3.72 seconds with an average of 3.2 seconds at Mustapha hospital junction and the average time of movement is 2.06 seconds. Similarly, drivers accept gaps ranging from 3.60 seconds and 4.5 seconds with an average of 4.05 seconds at Stadium Junction, and the average time of movement is 2.69 seconds. Comparing these values with the respective critical gaps from the Highway Capacity Manual shows that only values from stadium junction get close. This shows that the delays at the intersections are due mostly to driver impatience and intolerance which at times lead to accidents at the intersections. Hence, it can be concluded that traffic accidents at the intersections are due mostly to driver judgment rather than gap availability.

    teenage pregnancies are regarded as high risk, because they often occur outside marriage. There is the need to evaluate the outcome of teenage pregnancies in a predominantly Islamic society like Kano where most occur within marriage, and timely prenatal care is usually available to most of them. to review the obstetric outcome of teenage primigravida in Aminu Kano Teaching Hospital, Kano, Nigeria. a retrospective case-control study of 500 booked teenage primigravidae, who delivered in our labour ward from January 2002 to December 2005 (study group) was performed. Their obstetric outcome was compared with that of an equal number of booked primigravidae aged 20-34 years, who met the recruitment criteria and delivered immediately after a selected teenage mother (control group). The study variables of interest were the demographic characteristics of the women in the two groups, antenatal/intrapartum complications and neonatal outcome. there were no significant differences in the mean birth weight, mean gestational age at delivery, mean height and perinatal mortality between the two groups, but mean maternal weight and body mass index (BMI) were higher among the older women. The teenage mothers had increased incidence of preterm labour and low birth weight infants (P teenage mothers. the results of this study show that teenage mothers who receive good family and community support, timely quality antenatal care and deliver in the hospital, should expect similar obstetric outcome to that of their older peers.

    Full Text Available Romania's population has declined steadily from 23.2 million in 1990 to 21.5 million inhabitants in 2007. This overall decline in population is not entirely true for the towns and cities of the North-East Region, as during the same period they recorded both decreases and increases in population due to positive natural balance. The North-East Region (partially superimposed over the historic region of the western Moldova is considered the poorest region in the European Union and a disadvantaged area. The rural young population of Moldova is a reservoir which supplies urban areas and especially large cities. In these circumstances, the small towns of the North-East Region are seeking balance (demographic, economic, functional. This paper examines the demographic evolution of the small towns located in the area under analysis, in the post-communist period, illustrating the types of fluctuations in statistical methods as regards demographic changes and the risk of depopulation in the future, correlated with a lower overall population of Romania.

    Full Text Available Pentastomiasis is a parasitic zoonosis endemic to western and central Africa. This study was undertaken to determine the prevalence and public health implications of Linguatulosis in client-owned dogs in Jalingo, North Eastern Nigeria. Seven hundred and seventy seven (777 dogs brought for treatment at the hospital were subjected to buccal (sublingual examination for pentastomiasis. Parameters such as age, sex, and breeds were determined. Also, the months of the year were taken into consideration. An overall prevalence of 37.45% was recorded. Of the 477 dogs examined in 2010, 184 were positive representing prevalence of 38.57% and in 2011 107 were positive representing prevalence of 35.67%. The infection was higher in the male than in the female which does not differ significantly (P>0.05. There was no significant difference between sexes (P>0.05. However, significant difference (P<0.05 was observed between breeds and age of dogs examined. Season did not have much influence on the prevalence of Linguatulosis. The high prevalence of Linguatulosis in dogs and other animals found in this study highlights the need of improving preventative measures to reduce the rate of infection, which may pose a hazard to human health.

    Full Text Available Abstract Background A wide range of childhood illnesses are accompanied by fever,, including malaria. Child mortality due to malaria has been attributed to poor health service delivery system and ignorance. An assessment of a mother's ability to recognize malaria in children under-five was carried out among the Bwatiye, a poorly-served minority ethnic group in north-eastern Nigeria. Methods A three-stage research design involving interviews, participatory observation and laboratory tests was used to seek information from 186 Bwatiye mothers about their illness-related experiences with childhood fevers. Results Mothers classified malaria into male (fever that persists for longer than three days and female (fever that goes away within three days and had a system of determining when febrile illness would not be regarded as malaria. Most often, malaria would be ignored in the first 2 days before seeking active treatment. Self-medication was the preferred option. Treatment practices and sources of help were influenced by local beliefs, the parity of the mother and previous experience with child mortality. Conclusion The need to educate mothers to suspect malaria in every case of febrile illness and take appropriate action in order to expose the underlying "evil" will be more acceptable than an insistence on replacing local knowledge with biological epidemiology of malaria. The challenge facing health workers is to identify and exploit local beliefs about aetiology in effecting management procedures among culturally different peoples, who may not accept the concept of biological epidemiology.

    Full Text Available AIM: Glaucoma is becoming an increasingly important public health problem and presents a greater public health challenge because the blindness it causes is irreversible. This study is aimed at assessing the knowledge and risk factors for glaucoma among adults in Oke-ose community, Kwara State in North-Cental Nigeria. METHODS: This is a cross-sectional study which assessed the knowledge and risk factors for glaucoma among adults in a rural community of Kwara State. The respondents were selected using cluster sampling technique. Interviewer- administered semi-structured questionnaire was used to collect data. Data was analyzed using SPSS version 15. RESULTS: Less than half 94(47.0% respondents were aware of glaucoma. Only 11(5.5% respondents had some knowledge of symptoms and 18(9.0% had knowledge of the risk factors. Socio-economic status, age of respondents and educational status and family history of glaucoma among the respondents significantly influenced the awareness and knowledge of the disease (p<0.05. Among the respondents, a total of 22(11.0% and 37(18.5% were diabetic and hypertensive respectively. Only five (2.5% of respondents had high risk perception of glaucoma. CONCLUSION: The presence of risk factors for glaucoma coupled with the poor risk perception and poor knowledge of the disease require urgent community directed eye care interventions to reduce the devastating effects of glaucoma.

    Full Text Available Background. Necropsy (autopsy has helped medical science and law. It has given rise to numerous diagnostic surprises as it explains cause of death, pathogenesis of diseases, and circumstances of death. It also explains reasons for most therapeutic failures. In spite of its usefulness, the rate has dropped worldwide and Africa is worse hit. This work aims to highlight the role autopsy (Necropsy plays in demystifying diagnostic dilemmas and to encourage its patronage by medical practitioners, law enforcement agents and society. Methods. This is a retrospective review of autopsy and clinical reports of cases seen by pathologists and physicians in the Jos University Teaching Hospital (JUTH, Jos, North central Nigeria. Results. A total 166 cases were studied out of which 52 had same diagnosis for both attending physician and pathologist, 106 had different diagnoses and in eight cases diagnoses remained unknown even after autopsy was performed. Conclusions. Autopsy remains an important tool for obtaining definitive diagnosis, determining cause of death to explain pathogenesis of diseases, medical auditing and a vital source of data for health statistics and planning.

    Full Text Available An abattoir serological survey of brucellosis in pigs was conducted in Makurdi, Benue State North Central Nigeria between October and November 2011. Blood-sera were collected from a total of 281 slaughtered pigs and their ages and sex were recorded. The sera were tested for brucellosis using the Rose Bengal Plate Test (RBPT. A total of 86 of the 281 (30.60% pigs were serologically positive. The prevalence of positive pigs based on sex was 31.20% and 30.13% for male and female pigs, respectively. The age prevalence was 30.10% and 32.00% for young and adult pigs, respectively. There was no statistically significant association (p>0.05 between positivity of reactor pigs and their sex or age. This study concluded that brucellosis is a problem in the swine industry. Consequently, strict sanitary measures and control of swine brucellosis is urgently warranted to avoid spread of infection through pigs’ populations and their contacted persons as well as pork consumers.

    The paper investigated some of the beliefs around the breastfeeding norm of the postpartum abstinence and how these influence sexual behavior. It was based on a larger project which explored how gender relations affect reproductive processes and the reproductive health of Tarok women in north-central Nigeria. Research was conducted in four Tarok communities using qualitative instruments, namely in-depth interviews (IDIs) and focus group discussion (FGD) guides. Participants were female and male community members of 15 years and above. Sixteen IDIs (four per community) were conducted with women, religious and traditional leaders as well as senior health providers. Twenty-four FGD sessions (six per community) were held with different groups in the community and data were descriptively analyzed. Findings demonstrated customary double standards in sexual matters; the significance and influence of certain unfounded traditional beliefs around breastfeeding on sexual behavior and choices; as well as some of the changes that characterize sexual relationships among modern Tarok couples brought about by Christianity, Western education and modernity. Traditional breastfeeding norms and beliefs seek to overly control women's sexuality while giving precedence to the interest of the child and its father. The study calls for a change in attitude to meet the demands of the current reality in order to strengthen marital unions and guarantee healthy families. Copyright © 2013 Elsevier B.V.

    Full Text Available Introduction. Cancer of the cervix is the leading cause of cancer deaths among women in developing countries. Screening is one of the most cost effective control strategies for the disease. This study assessed the determinants of cervical cancer screening uptake among Nigerian women. Methodology. This cross-sectional study was conducted using multistage sampling technique among 338 participants in Ilorin, North Central Nigeria. A pretested questionnaire was used for data collection and data analysis was done using SPSS version 21. Chi-square test was used for bivariate analysis while binary logistic regression was used for multivariate analysis. Statistical significance was set at p<0.05. Results. Only 8.0% of the respondents had ever been screened for cancer of the cervix. The proportion of women who had ever been screened was significantly higher among those who demonstrated positive attitude to screening (81.5%, p=0.001, respondents who were aware of the disease (100.0%, p=0.001, and those who were aware of cervical cancer screening (88.9%, p=0.001. Respondents who had negative attitude had 63% lesser odds of being screened compared to those who had positive attitudes towards screening (AOR; 0.37, 95% CI; 0.01–0.28. Conclusion. There is urgent need to improve the knowledge base and attitude of Nigerian women to enhance cervical cancer screening uptake among them.

    Full Text Available Background. Decentralization of care and treatment for HIV infection in Africa makes services available in local health facilities. Decentralization has been associated with improved retention and comparable or superior treatment outcomes, but patient experiences are not well understood. Methods. We conducted a qualitative study of patient experiences in decentralized HIV care in Plateau State, north central Nigeria. Five decentralized care sites in the Plateau State Decentralization Initiative were purposefully selected. Ninety-three patients and 16 providers at these sites participated in individual interviews and focus groups. Data collection activities were audio-recorded and transcribed. Transcripts were inductively content analyzed to derive descriptive categories representing patient experiences of decentralized care. Results. Patient participants in this study experienced the transition to decentralized care as a series of “trade-offs.” Advantages cited included saving time and money on travel to clinic visits, avoiding dangers on the road, and the “family-like atmosphere” found in some decentralized clinics. Disadvantages were loss of access to ancillary services, reduced opportunities for interaction with providers, and increased risk of disclosure. Participants preferred decentralized services overall. Conclusion. Difficulty and cost of travel remain a fundamental barrier to accessing HIV care outside urban centers, suggesting increased availability of community-based services will be enthusiastically received.

    Full Text Available The aim of this study was to assess the flock characteristics, husbandry and productivity of indigenous chickens of Nasarawa State, Nigeria using questionnaire-based survey and on-site investigation. Responses were provided by 117 households cutting across the three agricultural zones of the state. Study agricultural zones did not differ (p>0.05 in the total number of birds owned per household. The mean (±SD household flock size was 13.9 (9.04 with a cock to hen ratio of 1:3.4. The low gene frequencies of naked neck (0.03 and frizzled (0.02 chickens in the population indicated that these dominant gene carriers are at the brink of extinction. Purchase from market was the main source of foundation stock (78.6%. Approximately 56% of the respondents provided partial enclosure for their birds. About 36% of the households claimed to offer partial feed supplements, such as maize, sorghum, millet, brans, sesame (beniseeds, and this was done in both wet and dry seasons. Women and children were the predominant providers of care for chickens. None of the households controlled the breeding of their flocks. Approximately 74% of respondents named Newcastle disease as the major health issue, and this could have been compounded by their lack of access to veterinary personnel. However, 33% of households claimed to use local herbs for the treatment of their birds. Rats were identified as the commonest predators attacking village chickens. Apart from number of eggs per clutch, cock and hen`s mortality/year that varied significantly (p

    Full Text Available Objectives. Sickle cell anaemia (SCA is one of the commonest genetic disorders in the world. It is characterized by anaemia, periodic attacks of thrombotic pain, and chronic systemic organ damage. Recent studies have suggested that individuals with SCA especially from developing countries are more likely to be iron deficient rather than have iron overload. The study aims to determine the iron status of SCA patients in Ilorin, Nigeria. Methods. A cross-sectional study of 45 SCA patients in steady state and 45 non-SCA controls was undertaken. FBC, blood film, sFC, sTfR, and sTfR/log sFC index were done on all subjects. Results. The mean patients’ serum ferritin (589.33 ± 427.61 ng/mL was significantly higher than the mean serum ferritin of the controls (184.53 ± 119.74 ng/mL. The mean serum transferrin receptor of the patients (4.24 ± 0.17 μg/mL was higher than that of the controls (3.96 ± 0.17 μg/mL (p=0.290. The mean serum transferrin receptor (sTfR/log serum ferritin index of the patients (1.65 ± 0.27 μg/mL was significantly lower than that of the control (1.82 ± 0.18 μg/mL (p=0.031. Conclusion. Iron deficiency is uncommon in SCA patients and periodic monitoring of the haematological, biochemical, and clinical features for iron status in SCA patients is advised.

    Although pityriasis versicolor (PV) is a common fungal infection of the skin affecting up to 50% of the population in the tropics, little is known about what patients know, believe, or feel about the condition. In a cross-sectional questionnaire study of 608 consecutive patients attending the General Outpatient Department and Skin Clinic of a public hospital in Kaduna, Nigeria, self-report of PV, knowledge about its causes, treatments used by patients, and perception and feelings about the condition were assessed. Overall 608 patients were studied (239/594 [40.2%] males, 355/594 [59.8%] females, age 11-49 years, mean ± SD age of 29.3 ± 10.1). Lifetime self-report prevalence of PV was 271/606 (44.7%) (males: 117/239 [50.0%] females: 148/355 [41.7%] P = 0.09). Three hundred and twenty-seven of 608 (53.8%) patients believed PV was transmitted from another person while 204/608 (33.6%) believed the condition was caused by poor personal hygiene. One hundred and thirty of 608 (21.4%) thought PV was caused by fungi living on the skin. Virtually all respondents who had PV had used at least one preparation with more than half visiting a healthcare facility. A total of 305/608 (50.2%), 189/608 (31.1%), and 142/608 (23.4%) respondents reported feeling or likely feeling uncomfortable, embarrassed, or ashamed, respectively, about PV. Being considered a dirty person (45.6%) and being avoided by other people (28%) were common concerns of respondents. Most patients did not know what caused PV, and many were uncomfortable, embarrassed, and ashamed, and feared being considered dirty and avoided by others. © 2017 The International Society of Dermatology.

    A large amount of radioactive materials, especially radiocesium, were discharged into the western North Pacific Ocean by the Fukushima Daiichi Nuclear Power Plant (FDNPP) disaster following the Great East Japan Earthquake and tsunami on 11 March 2011. Although radiocesium concentrations in sea water had quickly diminished via water mixing processes, significant amount still existed on sea floors near Fukushima Prefecture. To assess present distributions and/or spatio-temporal variations of sea sediment radiocesium and its potential affection to benthic ecosystems, we had conducted 5'x5' 2-D observation of sea sediment radiocesium concentrations repeatedly from Feb. 2012 to Jul. 2013. Off Fukushima Prefecture, the higher concentration area of radioactive cesium was often observed in the south area from the FDNPP and a north-south high value band was tended to be along the isobaths around 100 m where the concentration values up to thousands Bq/kg-dry order were observed. The concentrations generally decreased eastward from the high concentration band. At many surveyed positions, the vertical profiles of the radiocesium concentrations in sea sediment showed an exponentially decreasing in deeper layer. The influence of the FDNPP was suggested to generally reach up to 10 cm depth from sediment-surface. A negative correlation was found between the radiocesium concentration and median grain size of the sediment, suggesting that the adsorption capability of sediment for cesium associated with grain size possibly has a large contribution to the formation process of the spatial distribution pattern of the radiocesium concentration. In contrast to the land sediment, Chemical reaching experiment results showed that the radiocesium concentration in the organic component of bottom sediment has higher value than that of bulk sediment, suggesting that non-exchangeable adsorption cite of mineral component of marine sediments had already occupied by stable cesium (~2 nM in

  2. Sustainable Electricity and Water for Europe, Middle East and North Africa

    Sufficient supply of energy and water are among the key requirements for a sustainable development of nations. Both depend strongly on energy carriers such as oil, gas, coal and uranium which have limited availability and a negative impact on the environment during their use. Within the framework of a series of detailed studies, conventional and renewable energy sources available for electricity production and desalination in Europe, North Africa and the Middle East (EU-MENA) have been analysed. Scenarios have been developed for a sustainable electricity supply based on increased plant and user efficiency, and an accelerated introduction of renewable energy sources. Even if all potential exclusion criteria are applied and only those technologies are considered which will become economically competitive within the next decades, a potential has been identified which exceeds the present electricity demand by orders of magnitude. Solar energy is, in this context, the by far largest resource which will most economically be exploited in centralised solar thermal power plants. In combination with heat storage, these power plants can provide bulk and peak electricity, and can be combined with thermal or reverse osmosis desalination plants. At present, solar thermal power plants with a total capacity exceeding 10 GW are in operation or under construction in Abu Dhabi, Algeria, Egypt, Iran, Israel, Italy, Morocco, Spain and the USA. Ultimately, the increasing electricity demand of EU-MENA can only be secured in conjunction with the required climate and resource protection targets, if all renewable energy sources are exploited where appropriate, and conversion and user efficiency are increased. To utilise the enormous energy resources of the Mediterranean countries, high voltage direct current power lines will have to be built, linking the most abundant and economic resources with the load centres in the North.

  3. Controls on salt mobility and storage in the weathered dolerites of north-east Tasmania, Australia

    Changes in land use and vegetation due to agriculture, forestry practices and urbanisation can mobilise naturally occurring salts in the landscape and accelerate the expression of land and water salinisation, potentially threatening built and natural assets. Some salts are released during rock weathering or are derived from marine sediments or wind-blown dust, but in Tasmania most originate from salt dissolved in rainfall that is concentrated during evaporation. The volume of salts deposited over north-east Tasmania from precipitation exceeds 70kg/ha/year. The dominant lithology of the salt affected regions in Tasmania is dolerite which breaks down to form secondary minerals including: smectite and kaolinite clays and Fe-bearing sesquioxides. The weathering of Tasmanian dolerites, sampled from fresh corestones, weathering rinds and sequentially through the soil horizon, has been examined petrographically and geochemically. The EC1:5 increases with weathering to a maximum 4.9 dS/m and decreases in the pedogenic zone. This confirms field observations that deeply weathered dolerite can serve as a significant store for salt in the landscape. The water associated with dolerite weathering is typically a bicarbonate fluid. The pH1:5 decreases as the samples weather and increases in the pedogenic zone. Clay content increases with distance from corestones (sandy clay loam to heavy clay), and this is also reflected in the density (2.6-1.3 gm/cm3) and loss on ignition (1.3-13.3 wt%). The patterns for Na are complicated as it is enriched through NaCl accession and removed during the weathering of plagioclase. The net enrichment of Cl (up to 5239 ppm) implies decoupling of Cl from Na during weathering. Potassium, Ca and Sr are mobilised from the profile as plagioclase weathers, and silica is progressively lost from the profile with the weathering of silicate phases. Iron is initially mobilised with the weathering of pyroxene and mafic accessory minerals, but is rapidly fixed in

    Accurate estimates of water supply and demand are crucial elements in water resources management and modeling. As part of our NSF-funded EaSM effort to build a Northeast Regional Earth System Model (NE-RESM) as a framework to improve our understanding and capacity to forecast the implications of planning decisions on the region's environment, ecosystem services, energy and economic systems through the 21st century, we are producing a high resolution map (3' x 3' lat/long) of estimated water supply and use for the north east region of United States. Focusing on water demand, results from this study enables us to quantify how demand sources affect the hydrology and thermal-chemical water pollution across the region. In an attempt to generate this 3-minute resolution map in which each grid cell has a specific estimated monthly domestic, agriculture, thermoelectric and industrial water use. Estimated Use of Water in the United States in 2005 (Kenny et al., 2009) is being coupled to high resolution land cover and land use, irrigation, power plant and population data sets. In addition to water demands, we tried to improve estimates of water supply from the WBM model by improving the way it controls discharge from reservoirs. Reservoirs are key characteristics of the modern hydrologic system, with a particular impact on altering the natural stream flow, thermal characteristics, and biogeochemical fluxes of rivers. Depending on dam characteristics, watershed characteristics and the purpose of building a dam, each reservoir has a specific optimum operating rule. It means that literally 84,000 dams in the National Inventory of Dams potentially follow 84,000 different sets of rules for storing and releasing water which must somehow be accounted for in our modeling exercise. In reality, there is no comprehensive observational dataset depicting these operating rules. Thus, we will simulate these rules. Our perspective is not to find the optimum operating rule per se but to find

    Aluminum (Al) is the third most abundant metal in earth crust, whose chemical form is mainly dependent on soil pH. The most toxic form of Al with respect to plants is Al3+, which exists in soil pH Eastern India 80% soil are acidic). Al3+ toxicity in plants ensues root growth inhibition leading to less nutrient and water uptake impacting crop productivity as a whole. Rice is one of the chief grains which constitutes the staple food of two-third of the world population including India and is not untouched by Al3+ toxicity. Al contamination is a critical constraint to plant production in agricultural soils of North East India. 24 indigenous Indica rice varieties (including Badshahbhog as tolerant check and Mashuri as sensitive check) were screened for Al stress tolerance in hydroponic plant growth system. Results show marked difference in growth parameters (relative growth rate, Root tolerance index, fresh and dry weight of root) of rice seedlings due to Al (100 μM) toxicity. Al3+ uptake and lipid peroxidation level also increased concomitantly under Al treatment. Histochemical assay were also performed to elucidate uptake of aluminum, loss of membrane integrity and lipid peroxidation, which were found to be more in sensitive genotypes at higher Al concentration. This study revealed that aluminum toxicity is a serious harmful problem for rice crop productivity in acid soil. Based on various parameters studied it's concluded that Disang is a comparatively tolerant variety whereas Joymati a sensitive variety. Western blot hybridization further strengthened the claim, as it demonstrated more accumulation of Glutathione reductase (GR) protein in Disang rice variety than Joymati under stressed condition. This study also observed that the emergence of lethal toxic symptoms occurs only after 48h irrespective of the dose used in the study.

    This study quantifies the costs and impacts of six scenarios for carbon dioxide (CO 2 ) and sulphur dioxide (SO 2 ) emissions in North East Asia (NEA) within an integrated probabilistic analysis. The inclusion of the cooling effect of sulphates means that CO 2 control in China would be likely to increase the regional temperature in NEA in the short-term. This is because CO 2 control measures would also automatically control SO 2 emissions, and so reduce their cooling effect. The scenario that involves no control for CO 2 and SO 2 emissions has the lowest mean total cumulative net present cost (NPC) as compared to scenarios with various SO 2 controls or with CO 2 reduced to 5% below year 1990 levels (in China and Japan), or any combination of SO 2 + CO 2 controls at these levels. The mean value of the total cumulative NPC of climate change damage, acid rain damage, CO 2 and SO 2 control cost in China for no CO 2 or SO 2 control is about US$ 0.1 trillion, compared, for instance, to about US$ 1.1 trillion for CO 2 emission stabilisation at 1990 levels and no SO 2 control. SO 2 control also brings more disadvantages than advantages in China and Japan. The higher mean climate change impacts and control costs outweigh the benefit of lower acid rain damage. However, strict SO 2 control brings more benefits than costs in South Korea where there is a large urban population and the sensitivity to acid rain is high. However, the impacts of emissions and valuation of these effects are very uncertain. Uncertainty analysis shows that the key determinants of the total NPC of costs and damages are exported climate change damages, followed by domestic climate change damages, and acid rain damages. The use of other valuation methods would make health damage bigger than this study's estimation and acid rain damage could be a major concern in the future

    Elevated oxidative stress plays an important role in the pathogenesis of health disorders, like arthritis. Traditionally, Vespa affinis L., a common edible insect among many tribes in North-East India, is believed to have a beneficial role in extenuating health disorders, such as arthritis. The present study investigated the molecular mechanism underlying medicinal benefit of the Aqueous Extract of Vespa affinis L. (AEVA) against oxidative stress pathophysiology. The free radical scavenging activities of AEVA were examined against DPPH, hydroxyl, and superoxide radicals and the effect on the activities of antioxidant enzyme (GST and CAT) was determined using both recombinant proteins and human plasma. The antioxidant potential of AEVA was again investigated using THP-1 monocytes. AEVA possesses a significant free radical scavenging activity as evident from the DPPH, superoxide, and hydroxyl radical scavenging assay. Incubation of AEVA (2.5, 5, 7.5, and 10 μg/μL) with the recombinant antioxidant enzymes, rGST and rCAT significantly increased the enzyme activities compared to those observed in corresponding enzyme alone or AEVA itself. AEVA supplementation (5, 7.5, and 10 μg/μL) also stimulates the activities of GST and CAT when incubated with human plasma. A cell culture study also confirmed the beneficial role of AEVA (0.8 and 1.2 μg/μL) which enhances the activities of GST and CAT, and also reduces the intercellular ROS production in monocytes treated with or without H2O2 and the effects are at par with what is observed in N-acetyl cysteine-treated cells. The antioxidant potential of the aqueous extract of Vespa affinis L. may mediate its therapeutic activities in oxidative stress-associated health disorders.

    This article extends the recent findings of , , and by implementing recent bootstrap panel unit root tests and cointegration techniques to investigate the relationship between carbon dioxide emissions, energy consumption, and real GDP for 12 Middle East and North African Countries (MENA) over the period 1981–2005. Our results show that in the long-run energy consumption has a positive significant impact on CO 2 emissions. More interestingly, we show that real GDP exhibits a quadratic relationship with CO 2 emissions for the region as a whole. However, although the estimated long-run coefficients of income and its square satisfy the EKC hypothesis in most studied countries, the turning points are very low in some cases and very high in other cases, hence providing poor evidence in support of the EKC hypothesis. CO 2 emission reductions per capita have been achieved in the MENA region, even while the region exhibited economic growth over the period 1981–2005. The econometric relationships derived in this paper suggest that future reductions in CO 2 emissions per capita might be achieved at the same time as GDP per capita in the MENA region continues to grow. - Highlights: ► We study the links between CO 2 emissions, energy consumption and GDP in MENA region. ► Energy consumption has a positive correlation with CO 2 emissions. ► GDP exhibits a quadratic relationship with CO 2 emissions for the region as a whole. ► However, the turning points are low in some cases and high in other cases. ► Thus, not all countries need to sacrifice economic growth to decrease CO 2 emissions.

    Full Text Available Burnout is a popular research topics in service providing jobs, including the health care field. This study aimed at assessing the level of job burnout and to consider the important antecedents which might be related to job burnout among primary health care providers in Iran.The participants in this applied cross-sectional study which was conducted in 2013 were 548 primary health care providers who were randomly selected from among those working in Shahroud, Sabzevar, Neishabour, Bojnord (provinces located in the north east of Iran. Maslach Burnout Inventory (MBI was administered to the participants and the collected data were analyzed using SPSS through chi-square test and ordinal logistic regression model.The burnout mean score among the participants was 54.1 ± 27.2 and the mean scores of burnout components i.e., emotional exhaustion, depersonalization and personal accomplishment were 15.5 ± 13.6, 3.7 ± 5.4 and 35.5 ± 13.5 respectively. In terms of levels of burnout, 64.2% of the participants showed low levels (n = 352, 18.4% average levels (n = 101 and 17.3% high levels (n = 95. A significant relationship was observed between burnout, job resources and interest in job (p ≤ 0.05. However, no significant relationship was observed between burnout and the place (university of working, age, satisfaction with income, experience, gender, level of education, marital status, housing status, having a second job and place of residence (p ≥0.05.Lack of personal accomplishment was highly prevalent among the participating primary health care providers. Lack of career advancement and job transfer opportunities may play a role in the burnout of primary health care providers. Therefore, paying attention to this aspect may help to reduce burnout and even increase job engagement.

    Full Text Available A lake sediment sequence from southern Store Koldewey, north-east Greenland, has been investigated using a multidisciplinary approach, including geophysical, geochemical, biogeochemical, biological and sedimentological methods. Chronological constraints are provided by accelerator mass spectrometry (AMS 14C dating of bulk sediment and complemented with published water moss ages. The record consists of three major sediment units. Their individual structural, textural, geophysical and geochemical characteristics indicate variable input of sediment and meltwater due to variable proximity of the ice margin and therefore reflect the growth and decay of a local glacier during the late Weichselian. Radiocarbon dating of bulk sediment samples from the lowermost unit gave ages of 42 to 34 calibrated thousand years (cal Ky B.P. and indicates that this material is redeposited in the lake basin during or after the ice advance at the end of the Pleistocene. Increased meltwater and sediment input from a retreating ice margin following the Younger Dryas is indicated by the occurrence of a sandy to gravely section. Fine-grained and laminated sediments were deposited during the Pleistocene–Holocene transition and indicate calm sedimentation conditions with an ice margin outside of the lake catchment. The reoccurrence of coarse sediments during the early Holocene may indicate increased meltwater input in response to the cold spell at about 9.3 Kya with increased snow accumulation rather than fluctuations of local glaciers. The dating results furthermore show that AMS 14C dating of bulk sediment samples deposited during glacier decay in High Arctic environments can give problematic ages.

  12. The rise of clinical nutrition science in North-East Asia.

    Effective clinical nutrition practice depends on a sound knowledge of biomedical, societal and environmental science and the skills to diagnose, prevent and manage the health problems related to food patterns, energy equilibrium (mostly to do with physical activity) and nutrient metabolism. Its delivery needs to be accessible, equitable, affordable and sustainable. Ordinarily, this will require both local and widely distributed health services. In North-East (NE) Asia, these requisites are being met to an ever increasing extent. The roots of this progress are steeped in cultures which acknowledge the food-health connections and support education which pays regard to these connections. As elsewhere, however, the food and health systems, their safety and security are threatened by exploitative operatives. In China, a concerted effort was made in the mid-1980s to foster clinical nutrition in major hospitals throughout the country by programs directed at medical graduates, nursing and kitchen staff; dietetics has appeared much more recently. By contrast, Japan has had an extensive and well-trained dietetic workforce for much longer, alongside a vibrant basic nutrition science constituency in its universities and foodnutraceutical industry. South Korea and Taiwan have traversed a similar course to that in Japan. Now, all of these NE Asian economies have gathered rapid momentum in the publication of innovative approaches to public health and clinical nutrition which have the prospect of not only improving health outcomes, but also reducing the societal and financial burden of health care. This is particularly important in rapidly ageing societies, which they are. It is also a growing challenge where climate change threatens to engulf the lives and destinies of hundreds of millions of Asians on account of natural disasters, water and food insecurity.

    Vegetation biomass production in North-East India within Indo-Burma biodiversity hotspot is luxuriant and available from April to October to consider their potential for bioethanol production. Potential of six lignocellulosic biomass (LCB) sources; namely, sugarcane bagasse (BG), cassava aerial parts (CS), ficus fruits (Ficus cunia) (FF), “phumdi” (floating biomass), rice straw (RS), and sawdust were investigated for bioethanol production using standard techniques. Morphological and chemical changes were evaluated by Scanning electron microscopy and Fourier transform infrared spectroscopy and quantity of sugars and inhibitors in LCB were determined by High performance liquid chromatography. Hydrothermally treated BG, CS, and FF released 954.54, 1,354.33, and 1,347.94 mg/L glucose and 779.31, 612.27, and 1,570.11 mg/L of xylose, respectively. Inhibitors produced due to effect of hydrothermal pretreatment ranged from 42.8 to 145.78 mg/L acetic acid, below detection level (BDL) to 17.7 µg/L 5-hydroxymethylfurfural, and BDL to 56.78 µg/L furfural. The saccharification efficiency of hydrothermally treated LCB (1.35–28.64%) was significantly higher compared with their native counterparts (0.81–17.97%). Consolidated bioprocessing of the LCB using MTCC 1755 (Fusarium oxysporum) resulted in maximum ethanol concentration of 0.85 g/L and corresponded to 42 mg ethanol per gram of hydrothermally treated BG in 120 h followed by 0.83 g/L corresponding to 41.5 mg/g of untreated CS in 144 h. These ethanol concentrations corresponded to 23.43 and 21.54% of theoretical ethanol yield, respectively. LCB of CS and FF emerged as a suitable material to be subjected to test for enhanced ethanol production in future experiments through efficient fermentative microbial strains, appropriate enzyme loadings, and standardization of other fermentation parameters.

    Assessment of regional scale soil spatial variation and mapping their distribution is constrained by sparse data which are collected using field surveys that are labor intensive and cost prohibitive. We explored geostatistical (ordinary kriging-OK), regression (Regression Tree-RT), and hybrid methods (RT plus residual Sequential Gaussian Simulation-SGS) to map soil textural fractions across the Santa Fe River Watershed (3585 km(2)) in north-east Florida. Soil samples collected from four depths (L1: 0-30 cm, L2: 30-60 cm, L3: 60-120 cm, and L4: 120-180 cm) at 141 locations were analyzed for soil textural fractions (sand, silt and clay contents), and combined with textural data (15 profiles) assembled under the Florida Soil Characterization program. Textural fractions in L1 and L2 were autocorrelated, and spatially mapped across the watershed. OK performance was poor, which may be attributed to the sparse sampling. RT model structure varied among textural fractions, and the model explained variations ranged from 25% for L1 silt to 61% for L2 clay content. Regression residuals were simulated using SGS, and the average of simulated residuals were used to approximate regression residual distribution map, which were added to regression trend maps. Independent validation of the prediction maps showed that regression models performed slightly better than OK, and regression combined with average of simulated regression residuals improved predictions beyond the regression model. Sand content >90% in both 0-30 and 30-60 cm covered 80.6% of the watershed area. Copyright 2010 Elsevier Ltd. All rights reserved.

    Full Text Available The Global Atmospheric Watch research station at Mace Head (Ireland offers the possibility to sample some of the cleanest air masses being imported into Europe as well as some of the most polluted being exported out of Europe. We present a statistical cluster analysis of the physical characteristics of aerosol size distributions in air ranging from the cleanest to the most polluted for the year 2008. Data coverage achieved was 75% throughout the year. By applying the Hartigan-Wong k-Means method, 12 clusters were identified as systematically occurring. These 12 clusters could be further combined into 4 categories with similar characteristics, namely: coastal nucleation category (occurring 21.3 % of the time, open ocean nucleation category (occurring 32.6% of the time, background clean marine category (occurring 26.1% of the time and anthropogenic category (occurring 20% of the time aerosol size distributions. The coastal nucleation category is characterised by a clear and dominant nucleation mode at sizes less than 10 nm while the open ocean nucleation category is characterised by a dominant Aitken mode between 15 nm and 50 nm. The background clean marine aerosol exhibited a clear bimodality in the sub-micron size distribution, with although it should be noted that either the Aitken mode or the accumulation mode may dominate the number concentration. However, peculiar background clean marine size distributions with coarser accumulation modes are also observed during winter months. By contrast, the continentally-influenced size distributions are generally more monomodal (accumulation, albeit with traces of bimodality. The open ocean category occurs more often during May, June and July, corresponding with the North East (NE Atlantic high biological period. Combined with the relatively high percentage frequency of occurrence (32.6%, this suggests that the marine biota is an important source of new nano aerosol particles in NE Atlantic Air.

    Concern for the future of reef-building corals in conditions of rising sea temperatures combined with recent technological advances has led to a renewed interest in documenting the biodiversity of mesophotic coral ecosystems (MCEs) and their potential to provide lineage continuation for coral taxa. Here, we examine species diversity of staghorn corals (genera Acropora and Isopora) in the mesophotic zone (below 30 m depth) of the Great Barrier Reef and western Coral Sea. Using specimen-based records we found 38 staghorn species in the mesophotic zone, including three species newly recorded for Australia and five species that only occurred below 30 m. Staghorn corals became scarce at depths below 50 m but were found growing in-situ to 73 m depth. Of the 76 staghorn coral species recorded for shallow waters (depth ≤ 30 m) in north-east Australia, 21% extended to mesophotic depths with a further 22% recorded only rarely to 40 m depth. Extending into the mesophotic zone provided shallow water species no significant advantage in terms of their estimated global range-size relative to species restricted to shallow waters (means 86.2 X 10(6) km2 and 85.7 X 10(6) km2 respectively, p = 0.98). We found four staghorn coral species at mesophotic depths on the Great Barrier Reef that were previously considered rare and endangered on the basis of their limited distribution in central Indonesia and the far western Pacific. Colonies below 40 m depth showed laterally flattened branches, light and fragile skeletal structure and increased spacing between branches and corallites. The morphological changes are discussed in relation to decreased light, water movement and down-welling coarse sediments. Staghorn corals have long been regarded as typical shallow-water genera, but here we demonstrate the significant contribution of this group to the region's mesophotic fauna and the importance of considering MCEs in reef biodiversity estimates and management.

  18. Water runoff vs modern climatic warming in mountainous cryolithic zone in North-East Russia

    2018-01-01

    The article presents the results of studying the effects of current climatic warming for both surface and subsurface water runoffs in North-East Russia, where the Main Watershed of the Earth separates it into the Arctic and Pacific continental slopes. The process of climatic warming is testified by continuous weather records during 80-100 years and longer periods. Over the Arctic slope and in the northern areas of the Pacific slope, climatic warming results in a decline in a total runoff of rivers whereas the ground-water recharge becomes greater in winter low-level conditions. In the southern Pacific slope and in the Sea of Okhotsk basin, the effect of climatic warming is an overall increase in total runoff including its subsurface constituents. We believe these peculiar characters of river runoff there to be related to the cryolithic zone environments. Over the Arctic slope and the northern Pacific slope, where cryolithic zone is continuous, the total runoff has its subsurface constituent as basically resulting from discharge of ground waters hosted in seasonally thawing rocks. Warmer climatic conditions favor growth of vegetation that needs more water for the processes of evapotranspiration and evaporation from rocky surfaces in summer seasons. In the Sea of Okhotsk basin, where the cryolithic zone is discontinuous, not only ground waters in seasonally thawing layers, but also continuous taliks and subpermafrost waters participate in processes of river recharges. As a result, a greater biological productivity of vegetation cover does not have any effect on ground-water supply and river recharge processes. If a steady climate warming is provided, a continuous cryolithic zone can presumably degrade into a discontinuous and then into an island-type permafrost layer. Under such a scenario, there will be a general increase in the total runoff and its subsurface constituent. From geoecological viewpoints, a greater runoff will have quite positive effects, whereas some

    Full Text Available Climate change is one of the major environmental challenges facing the world. Particularly vulnerable are arid and low-laying coastal areas, conditions that prevail through most of the Middle East and North Africa [MENA]. This region is an economically diverse one, including both the oil-rich economies in the Gulf and countries that are resource-scarce in relation to their population.  However, with about 23 percent of MENA’s population living on less than $2 a day, it is imperative that the climate change management strategies adopted be cost-effective and emphasize economic, social and human development while addressing the concerns arising from anthropogenic climate change.Over the past decades several national and international mechanisms were developed in an attempt to reduce the emissions considered to be mainly responsible for climate change, and to assist in coping with the adverse effects that are beginning to occur as a result of climate change. Unfortunately, many of these approaches are presently associated with economic penalties that often adversely affect the socio-economic welfare of the populace, particularly in low-, and medium-income countries. In this regard, it is informative to note the experience recently gained by Trinidad and Tobago [T&T] in its attempt to reduce GHG emissions without affecting the competitiveness of the industrial and agricultural sectors. Using appropriate decision making tools and a policy environment based on a combination of regulations and incentives, the environmental challenges can be turned into a vehicle for sustainable development.This paper discusses the factors that need to be considered while developing a sustainable climate change management approach for the MENA region and develops some recommendations that may be essential for achieving the desired climate change mitigation/adaptation actions while minimizing social disruption.

The burnout mean score among the participants was 54.1 ± 27.2 and the mean scores of burnout components i.e., emotional exhaustion, depersonalization and personal accomplishment were 15.5 ± 13.6, 3.7 ± 5.4 and 35.5 ± 13.5 respectively. In terms of levels of burnout, 64.2% of the participants showed low levels (n = 352), 18.4% average levels (n = 101) and 17.3% high levels (n = 95). A significant relationship was observed between burnout, job resources and interest in job (p ≤ 0.05). However, no significant relationship was observed between burnout and the place (university) of working, age, satisfaction with income, experience, gender, level of education, marital status, housing status, having a second job and place of residence (p ≥0.05). Lack of personal accomplishment was highly prevalent among the participating primary health care providers. Lack of career advancement and job transfer opportunities may play a role in the burnout of primary health care providers. Therefore, paying attention to this aspect may help to reduce burnout and even increase job engagement.

    We present liquid freshwater transports of the shelfbreak East Greenland Current (EGC) and the separated EGC determined from mooring records from the Kögur section north of Denmark Strait between August 2011 and July 2012. The 11-month mean freshwater transport (FWT) of these two branches was 65±11 mSv to the south (relative to a salinity of 34.8). Approximately 70% of this was associated with the shelfbreak EGC and the remaining 30% with the separated EGC. Very large southward FWT ranging from 160 mSv to 120 mSv was observed from September to mid-October 2011 and was foremost due to anomalously low upper-layer salinities. The FWT on the Greenland shelf was also estimated using additional inshore moorings deployed from 2012-2014. While the annual mean ranged from nearly zero during the first year to 18 mSv to the south during the second year, synoptically the FWT on the shelf can be significant. Furthermore, an anomalous event in autumn 2011 caused the shelfbreak EGC to reverse, leading to a large reduction in FWT. This reversed circulation was due to the passage of a large, 100 km wide anticyclone originating upstream from the shelfbreak. The late summer FWT of -131 mSv is two and a half times larger than earlier estimates based on sections in the late-1990s and early-2000s. This increase is likely the result of enhanced freshwater flux from the Arctic Ocean to the Nordic Seas during the early 2010s when also a significant increase of Pacific Water in the EGC was observed. Preliminary results obtained from the long-term ocean observing system in Fram Strait are included to compare the increased FWT seen in 2011-2012 with interannual variations in Arctic freshwater outflow during the last decade.

It further attempts to understand, using a multi-disciplinary approach, how the safety codes/standards in diagnostic radiology framed by the Atomic Energy Regulatory Board (AERB) and the International Atomic Energy Agency (IAEA) to achieve adequate radiological protection in facilities, have been perceived, conceptualized, and applied accordingly in these facilities. About 30 diagnostic radiology facilities were randomly selected from three capitals of states in NE India; namely Imphal (Manipur), Shillong (Meghalaya) and Guwahati (Assam). A semi-structured questionnaire developed based on a multi-disciplinary approach was used for this study. It was observed that radiological practices undertaken in these facilities were not exactly in line with safety codes/standards in diagnostic radiology of the AERB and the IAEA. About 50% of the facilities had registered/licensed x-ray equipment with the AERB. More than 80% of the workers did not use radiation protective devices, although these devices were available in the facilities. About 85% of facilities had no institutional risk management system. About 70% of the facilities did not carry out periodic quality assurance testing of their x-ray equipment or surveys of radiation leakage around the x-ray room, and did not display radiation safety indicators in the x-ray rooms. Workers in these facilities exhibited low risk perception about the risks associated with these practices. The majority of diagnostic radiology facilities in NE India did not comply with the radiological safety codes/standards framed by the AERB and IAEA. The study found inadequate levels of radiological protection systems in the majority of facilities. This study suggests a need to establish firm measures that comply with the radiological safety codes/standards of the

    Full Text Available Background Despite recent pharmaceutical advancements in the production of new antibiotics, antibiotic resistance is increasing at an alarming rate in mammals; given the high prevalence of infectious diseases. Objectives The current study aimed to determine the epidemiology of different infections in patients admitted to the infectious disease ward of Imam Reza hospital in Mashhad, North-East of Iran. Methods This cross-sectional study was conducted on 1681 patients referred to Imam Reza hospital of Mashhad during 2006 - 2008. Prepared checklists were used to collect the required data, including age, gender, employment status, place of residence, length of hospitalization and season of admission in patients diagnosed with infectious diseases. Results In the current study, prevalence of tuberculosis, septicemia, skin and soft tissue infections, urinary tract infections (UTIs, febrile neutropenia, myocarditis, and gastrointestinal infections were estimated at 8.4%, 8.3%, 7.1%, 5.4%, 4.9%, 3.9%, and 3.8%, respectively. Also, major respiratory infections were reported in 5.8% of the studied patients. Among the female patients in the study, 20.9% and 10.56% were diagnosed with pneumonia and tuberculosis, respectively. As for the male patients, 16.1%, 10.7%, and 7.1% were diagnosed with pneumonia, nervous system infections and tuberculosis, respectively. Conclusions According to the results of the study, the most common causes of hospital admission were respiratory infections (e.g. pneumonia, nervous system infections, tuberculosis, septicemia, skin and soft tissue infections and UTIs. Considering the diversity of infections, epidemiological evaluation of these diseases is essential, especially in regions with high prevalence of infectious diseases. Furthermore, etiological diagnosis is considered imperative for clinicians before initiating therapy in patients with infectious diseases.

    The precipitation variability associated with the East Asian summer monsoon (EASM) has profound societal implications. Here, we use precisely dated and seasonally-resolved stalagmite oxygen isotope (δ 18 O) records from Shihua Cave, North China to reconstruct the EASM variability over the last 145 years. Our record shows a remarkable weakening of the EASM strength since the 1880s, which may be causally linked to the warming of the tropical Pacific and Indian Oceans. The δ 18 O record also exhibits a significant ~30-year periodicity, consistent with the instrumental, historical and proxy-based rainfall records from North China, plausibly driven by the Pacific Decadal Oscillation (PDO). Together, these observations imply that ~30-year periodicity is a persistent feature of the EASM, which remains significant with or without anthropogenic forcing. If indeed, the EASM rainfall in North China might decline significantly in the near future, which may affect millions of people in this region.

    To investigate eating disorder psychopathology, restraint and eating concern in young women with and without an eating disorder from two different ethnic groups in Australia and Singapore. The relationship of Eating Disorder Examination Questionnaire Global, Restraint and Eating Concern scores to cultural orientation and sociocultural factors was analysed in 154 women with and without an eating disorder. Participants were from the following backgrounds: North European Australian, East Asian Australian, Singaporean Chinese and North European expatriates in Singapore. Women with eating disorders had similar psychopathology across the cultural groups. Among controls, Singaporean Chinese reported significantly greater overall eating disorder psychopathology than other cultural groups and greater restraint than North European Australians/expatriates. Eating concern was not associated with cultural group overall or acculturation to Western culture. Dissatisfaction with family functioning, socioeconomic status and education level were not significantly associated with any of the eating disorder measures. In eating disorder psychopathology, the specific symptom of eating concern may transcend cultural influences.

    Cancer is becoming the most important public health burden around the globe. As per the GLOBOCAN 2008 estimates, about 12.7 million cancer cases and 7.6 million cancer deaths were estimated to have occurred in 2008. The burden of cancer cases for India in the year 2020 is calculated to be 1,148,757 (male 534,353; female 614,404) compared to 979,786 in 2010. The pattern of cancer incidence is varying among geographical regions, esophageal cancer for example being high in China, lung cancer in USA, and gallbladder cancer in Chile. The question remains why? Is it due to the diversity in genome pool, food habits, risk factor association and role of genetic susceptibility or some other factors associated with it? In India, the North East (NE)-India region is seeing a marked increase in cancer incidence and deaths, with a very different cancer incidence pattern compared to mainland India. The genome pool of the region is also quite distinct from the rest of India. Northeastern tribes are quite distinct from other groups; they are more closely related to East Asians than to other Indians. In this paper an attempt was made to see whether there is any similarity among the pattern of cancer incidence cases for different sites of NE-India region to South or East-Asia. Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), Pearson Correlation coefficient test was assessed to evaluate the linkage of North-East India region to other regions. A p value NE-India with South and East-Asian regions, which may lead to the conclusion that there might be a genetic linkage between these regions.

    Climatology-based storage rate of anthropogenic CO2 (Cant, referred to year 2000) in the North-East Atlantic (53 ± 9 kmol s-1, 0.020 ± 0.003 Pg-C yr-1) is described on annual mean terms. Cant advection (32 ± 14 kmol s-1) occurs mostly in the upper 1800 m and contributes to 60% of the Cant storage rate. The Azores and Portugal Currents act as 'Cant streams' importing 389 ± 90 kmol s-1, most of which recirculates southwards with the Canary Current (-214 ± 34 kmol s-1). The Azores Counter Current (-79 ± 36 kmol s-1) and the northward-flowing Mediterranean Water advective branch (-31 ± 12 kmol s-1) comprise secondary Cant export routes. By means of Cant transport decomposition, we find horizontal circulation to represent 11% of the Cant storage rate, while overturning circulation is the main driver (48% of the Cant storage rate). Within the domain of this study, overturning circulation is a key mechanism by which Cant in the upper layer (0-500 dbar) is drawdown (74 ± 14 kmol s-1) to intermediate levels (500-2000 dbar), and entrained (37 ± 7 kmol s-1) into the Mediterranean Outflow Water to form Mediterranean Water. This newly formed water mass partly exports Cant to the North Atlantic at a rate of -39 ± 9 kmol s-1 and partly contributes to the Cant storage in the North-East Atlantic (with up to 0.015 ± 0.006 Pg-C yr-1). Closing the Cant budget, 40% of the Cant storage in the North-East Atlantic is attributable to anthropogenic CO2 uptake from the atmosphere (21 ± 10 kmol s-1).

    The transport of North American (NA) ozone to East Asia is investigated through the analysis of a 20 year simulation (1987-2006) using a global chemical transport model (GEOS-Chem) and forward trajectories during the 1990s at three NA sites. NA ozone mainly influences northern East Asia (> 30°N), where NA ozone in the free troposphere peaks in spring and fall ( 12 ppbv). At the surface, NA ozone ranges from 2 to 7 ppbv and peaks in winter, 50% of which is from the NA boundary layer. The seasonality of the imported NA ozone reflects the combined effects of meteorology and chemistry. In summer, NA ozone can be diverted from reaching East Asia by strong downdrafts behind the European trough. In winter, the prevailing monsoon climate in East Asia can boost downdrafts of NA ozone to the surface. In spring and fall, the westerlies are stronger and shift farther south than in summer, bring more NA ozone to the East Asian (EA) free troposphere than in summer. The imported NA ozone at the EA surface also varies with interannual meteorology. This interannual variation is found to closely correlate to the East Asian winter monsoon (EAWM). The stronger the EAWM in a winter is, the stronger are the downdrafts bringing more NA ozone to the EA surface in that winter and the subsequent spring. Because the anthropogenic NA emissions have decreased since 1999, the year an emission inventory was used in the simulation, the simulated NA influence may serve as an upper limit.

    mHealth practitioners seek to leverage the ubiquity of the mobile phone to increase the impact and robustness of their interventions, particularly in resource-limited settings. However, data on the reliability of self-reported mobile phone access is minimal. We sought to ascertain the reliability of self-reported ownership of and access to mobile phones among a population of rural dwellers in north-central Nigeria. We contacted participants in a community-based HIV testing program by phone to determine actual as opposed to self-reported mobile phone access. A phone script was designed to conduct these calls and descriptive analyses conducted on the findings. We dialed 349 numbers: 110 (31.5%) were answered by participants who self-reported ownership of the mobile phone; 123 (35.2%) of the phone numbers did not ring at all; 28 (8.0%) rang but were not answered; and 88 (25.2%) were answered by someone other than the participant. We reached a higher proportion of male participants (68/133, 51.1%) than female participants (42/216, 19.4%; Preliability of self-reported mobile phone access. These observations should therefore affect sample-size calculations and, where possible, alternative means of reaching research participants and program beneficiaries should be established. ©William Nii Ayitey Menson, John Olajide Olawepo, Tamara Bruno, Semiu Olatunde Gbadamosi, Nannim Fazing Nalda, Victor Anyebe, Amaka Ogidi, Chima Onoka, John Okpanachi Oko, Echezona Edozie Ezeanolue.

    Full Text Available This study assessed the change in some environmental parameters in the Plateau region of North-Central Nigeria (Barakinladi, Jos, and Kafachan environs using the nexus of landcover change, land surface temperature, surface albedo, and topography. The study employed both remote sensing and statistical techniques for the period between 1986 and 2014 to analyze the dynamics between and within these environmental variables. In Barakinladi, the built up landcover change is highest (increasing from 39.53% to 47.59% between 1986 and 2014; LST ranges from 19.09 °C to 38.59 °C in 1986 and from 22.68 °C and 41.68 °C in 2014; and the albedo ranges between 0.014 and 0.154 in 1986 and 0.017 and 0.248 in 2014. In Jos, the built-up landcover occupied 34.26% in 1986 and 36.67% in 2014; LST values range between 20.83 °C and 41.33 °C in 1986 and between 21.61 °C and 42.64 °C in 2014; and the albedo ranges between 0.003 and 0.211 in 1986 and 0.15 and 0.237 in 2014. In Kafachan area, the built up landcover occupied 32.95% in 1986 and 39.01% in 2014. Urbanization and agricultural activities, including animal grazing, were responsible for the gradual loss in vegetation and increasing average LST and albedo. The results also revealed that changing landcover and topography have a relationship with surface albedo and land surface temperature, thereby impacting significantly on ecosystem services delivered by the natural system.

    Full Text Available Abstract Background Interest in the reproductive health of adolescents continues to grow throughout the world. Few studies had explored the reproductive health knowledge, sexual behavior and experience of sexual coercion among secondary school students in North Eastern states of Nigeria. The objectives of this descriptive survey were to collect data to plan appropriate interventions that meet the reproductive health knowledge, service and skills needs of students in Bauchi, Borno and Gombe states. Methods Face-to-face interviews were conducted for 624 consenting students who were randomly selected from eighteen secondary schools using an 83-item structured questionnaire. Data were collected on demographic profile, reproductive health knowledge, sexual behavior and experience of sexual coercion. Results The mean age of the respondents was 16.5 years. There were slightly more males (52% than females (48%. Students' knowledge about reproductive health was generally low even though girls had better knowledge than boys. Thirteen percent of the entire students had had sexual experience; significantly more males (19% than females (6% had done so (p Among boys the age at sexual debut ranged from 10–26 with a mean of 15.7 and median of 16. By contrast, the age at first sex among girls ranged from 10 to 18 years with a mean and median of 16.1 and 17 years respectively. Only 24% of those who were sexually active used a condom during their last sexual encounter. Overall 11% of the students reported that they had been tricked into having sex, 9% had experienced unwanted touch of breast and backside, and 5% reported rape. Conclusion Students low reproductive health knowledge and involvement in risky sexual activities predispose them to undesirable reproductive health outcomes.

    As part of its Global Change Hydrology Program, the U.S. Geological Survey (USGS) is investigating the potential effects of climate change on the water resources of several river basins in the United States. The American River Basin in California represents the windward slope of the north-central Sierra Nevada, and the California part of the Carson River Basin, most of which is in Nevada, represents the leeward slope. Parts of the American River and Carson River Basins—the North Fork American River and East Fork Carson River watersheds, both in California—were studied to determine the sensitivity of water resources to potential climate change. The water resources of both basins are derived primarily from snowmelt. A geographic information system (GIS) data base has been created to facilitate paired-basin analysis. The GIS data base incorporates (1) land-surface data, which include elevation, land use and land cover, soil type, and geology; (2) hydrologic data, such as stream networks and streamflow-gaging stations; and (3) climatic data, such as snow-course, snow-telemetry, radiosonde, and meteorological data. Precipitation-runoff models were developed and calibrated for the North Fork watershed within the American River Basin and for the East Fork watershed within the Carson River Basin. (These watersheds were selected to represent the climatic and physiographic variability of the two larger basins.) Synthesized climate scenarios then were used in the model to predict potential effects of climate change.

    Improving hydrological forecasting systems on different time scales is interesting and challenging with regards to humanitarian as well as scientific aspects. In meteorological research, short-, medium-, and long-term forecasts are now being merged to form a system of seamless weather and climate predictions. Coupling of these meteorological forecasts with a hydrological model leads to seamless predictions of streamflow, ranging from one day to a season. While there are big efforts made to analyse the uncertainties of probabilistic streamflow forecasts, knowledge of the single uncertainty contributions from meteorological and hydrological modeling is still limited. The overarching goal of this project is to gain knowledge in this subject by decomposing and quantifying the overall predictive uncertainty into its single factors for the entire seamless forecast horizon. Our study area is the Mahanadi River Basin in North-East India, which is prone to severe floods and droughts. Improved streamflow forecasts on different time scales would contribute to early flood warning as well as better water management operations in the agricultural sector. Because of strong inter-annual monsoon variations in this region, which are, unlike the mid-latitudes, partly predictable from long-term atmospheric-oceanic oscillations, the Mahanadi catchment represents an ideal study site. Regionalized precipitation forecasts are obtained by applying the method of expanded downscaling to the ensemble prediction systems of ECMWF and NCEP. The semi-distributed hydrological model HYPSO-RR, which was developed in the Eco-Hydrological Simulation Environment ECHSE, is set up for several sub-catchments of the Mahanadi River Basin. The model is calibrated automatically using the Dynamically Dimensioned Search algorithm, with a modified Nash-Sutcliff efficiency as objective function. Meteorological uncertainty is estimated from the existing ensemble simulations, while the hydrological uncertainty is

    Tattooing has become increasingly popular, particularly among young people. However, little is known about the tattoo practices in North-East India. The primary objective of this study was to know the reasons and motivations of tattoo application and tattoo removal in individuals asking for tattoo removal. The secondary objective was to identify the demography, methods and safety of tattoo practices in these tattooed individuals. A hospital-based cross-sectional study was carried out in 212 consecutive individuals seeking tattoo removal. Chi-square and Fisher's exact tests were performed for intergroup comparisons. There were 178 (84%) males and 34 (16%) females. The mean ± standard deviation (SD) age of individuals seeking tattoo removal was 21.8 ± 4 years. The mean ± SD age of doing tattoo was 15.8 ± 3 years. Most individuals possessed an amateur tattoo (94.3%), 4.2% a professional one and 1.4% had a combination. Sewing needle was the most common instrument used for making tattoos in 51.4%. The individuals made their tattoos in an unsterile manner in 49.1%. The most common reason for doing tattoo was for fashion in 87.7%. The participants wanted tattoo removal to qualify for jobs, especially in armed forces in 49.5% and due to regret in 21.7%. Black was the most preferred colour in 37.3% followed by green in 28.3%. The fabric ink was the choice of ink in maximum number of individuals, i.e. 93.9%. It was a hospital-based study done only on individuals seeking tattoo removal. It needs caution to generalise the findings in population. In addition, there may be recall bias in the participants. The tattoo was done mostly below 18 years of age in a crude unsterile way. The individuals had poor risk perceptions about various infections and complications of tattooing. There is an urgent need to caution and educate the youngsters and school-going children about safe tattooing and consequences of tattooing.

    Full Text Available Abstract Background There is good evidence for the effectiveness of opioid substitution therapy (OST for injecting drug users (IDUs in middle and high-income countries but little evidence regarding the provision of OST by non-government organisations (NGOs in resource-poor settings. This paper reports on outcomes of an NGO-based OST program providing sub-lingual buprenorphine to opiate dependent IDUs in two north-east Indian states (Manipur and Nagaland, a region where conflict, under-development and injecting of heroin and Spasmoproxyvon (SP are ongoing problems. The objectives of the study were: 1 to calculate OST treatment retention, 2 to assess the impact on HIV risk behaviours and quality of life, and 3 to identify client characteristics associated with cessation of treatment due to relapse. Methods This study involves analysis of data that were routinely and prospectively collected from all clients enrolled in an OST program in Manipur and Nagaland between May 2006 and December 2007 (n = 2569, 1853 in Manipur and 716 in Nagaland using standardised questionnaires, and is best classified as operational research. The data were recorded at intake into the program, after three months, and at cessation. Outcome measures included HIV risk behaviours and quality of life indicators. Predictors of relapse were modelled using binary logistic regression. Results Of all clients enrolled in OST during the month of May 2006 (n = 713, 72.8% remained on treatment after three months, and 63.3% after six months. Statistically significant (p = 0.05 improvements were observed in relation to needle sharing, unsafe sex, incidents of detention, and a range of quality of life measures. Greater spending on drugs at intake (OR 1.20, frequently missing doses (OR 8.82, and having heroin rather than SP as the most problematic drug (OR 1.95 were factors that increased the likelihood of relapse, and longer duration in treatment (OR 0.76 and regular family involvement in

    Background and Aims Myrmecochory is a conspicuous feature of several sclerophyll ecosystems around the world but it has received little attention in the semi-arid areas of South America. This study addresses the importance of seed dispersal by ants in a 2500-km2 area of the Caatinga ecosystem (north-east Brazil) and investigates ant-derived benefits to the plant through myrmecochory. Methods Seed manipulation and dispersal by ants was investigated during a 3-year period in the Xingó region. Both plant and ant assemblages involved in seed dispersal were described and ant behaviour was characterized. True myrmecochorous seeds of seven Euphorbiaceae species (i.e. elaiosome-bearing seeds) were used in experiments designed to: (1) quantify the rates of seed cleaning/removal and the influence of both seed size and elaiosome presence on seed removal; (2) identify the fate of seeds dispersed by ants; and (3) document the benefits of seed dispersal by ants in terms of seed germination and seedling growth. Key Results Seed dispersal by ants involved one-quarter of the woody flora inhabiting the Xingó region, but true myrmecochory was restricted to 12·8 % of the woody plant species. Myrmecochorous seeds manipulated by ants faced high levels of seed removal (38–84 %) and 83 % of removed seeds were discarded on ant nests. Moreover, seed removal positively correlated with the presence of elaiosome, and elaiosome removal increased germination success by at least 30 %. Finally, some Euphorbiaceae species presented both increased germination and seedling growth on ant-nest soils. Conclusions Myrmecochory is a relevant seed dispersal mode in the Caatinga ecosystem, and is particularly frequent among Euphorbiaceae trees and shrubs. The fact that seeds reach micro-sites suitable for establishment (ant nests) supports the directed dispersal hypothesis as a possible force favouring myrmecochory in this ecosystem. Ecosystems with a high frequency of myrmecochorous plants appear not

    Dust-climate interaction over the Middle East and North Africa (MENA) has long been studied, as it is the "dustiest" region on earth. However, the quantitative and qualitative understanding of the role of dust direct radiative effect on MENA climate is still rudimentary. The present dissertation investigates dust direct radiative effect on MENA climate during summer with a special emphasis on the sensitivity of climate response to dust shortwave absorption, which is one of the most uncertain components of dust direct radiative effect. Simulations are conducted with and without dust radiative effect, to differentiate the effect of dust on climate. To elucidate the sensitivity of climate response to dust shortwave absorption, simulations with dust assume three different cases of dust shortwave absorption, representing dust as a very efficient, standard and inefficient shortwave absorber. The non-uniformly distributed dust perturb circulations at various scales. Therefore, the present study takes advantage of the high spatial resolution capabilities of an Atmospheric General Circulation Model (AGCM), High Resolution Atmospheric Model (HiRAM), which incorporates global and regional circulations. AMIP-style global high-resolution simulations are conducted at a spatial resolution of 25 km. A significant response in the strength and position of the local Hadley circulation is predicted in response to meridionally asymmetric distribution of dust and the corresponding radiative effects. Significant responses are also found in regional circulation features such as African Easterly Jet and West African Monsoon circulation. Consistent with these dynamic responses at various scales, the tropical rainbelt across MENA strengthens and shifts northward. Similarly, the temperature under rainbelt cools and that over subtropical deserts warms. Inter-comparison of various dust shortwave absorption cases shows that the response of the MENA tropical rainbelt is extremely sensitive to the

    Full Text Available We use satellite observations of aerosol optical depth (AOD from the Moderate Resolution Imaging Spectrometer (MODIS together with the GEOS-Chem global chemical transport model to contrast export of aerosols from East Asia and North America during 2004–2010. The GEOS-Chem model reproduces the spatial distribution and temporal variations of Asian aerosol outflow generally well, although a low bias (−30% is found in the model fine mode AOD, particularly during summer. We use the model to identify 244 aerosol pollution export events from E. Asia and 251 export events from N. America over our 7-year study period. When these events are composited by season, we find that the AOD in the outflow is enhanced by 50–100% relative to seasonal mean values. The composite Asian plume splits into one branch going poleward to the Arctic in 3–4 days, with the other crossing the Pacific Ocean in 6–8 days. A fraction of the aerosols is trapped in the subtropical Pacific High during spring and summer. The N. American plume travels to the northeast Atlantic, reaching Europe after 4–5 days. Part of the composite plume turns anticyclonically in the Azores High, where it slowly decays. Both the Asian and N. American export events are favored by a dipole structure in sea-level pressure anomalies, associated with mid-latitude cyclone activity over the respective source regions. This dipole structure during outflow events is a strong feature for all seasons except summer, when convection becomes more important. The observed AOD in the E. Asian outflow exhibits stronger seasonality, with a spring maximum, than the N. American outflow, with a broad spring/summer maximum. The large spring AOD in the Asian outflow is the result of enhanced sulfate and dust aerosol concentrations, but is also due to a larger export efficiency of sulfate and SO2 from the Asian boundary layer relative to the N. American boundary layer. While the N. American sulfate outflow

    Several developing countries seek to build knowledge-based economies by attempting to expand scientific research capabilities. Characterizing the state and direction of progress in this arena is challenging but important. Here, we employ three metrics: a classical metric of productivity (publications per person), an adapted metric which we denote as Revealed Scientific Advantage (developed from work used to compare publications in scientific fields among countries) to characterize disciplinary specialty, and a new metric, scientific indigeneity (defined as the ratio of publications with domestic corresponding authors) to characterize the locus of scientific activity that also serves as a partial proxy for local absorptive capacity. These metrics-using population and publications data that are available for most countries-allow the characterization of some key features of national scientific enterprise. The trends in productivity and indigeneity when compared across other countries and regions can serve as indicators of strength or fragility in the national research ecosystems, and the trends in specialty can allow regional policy makers to assess the extent to which the areas of focus of research align (or not align) with regional priorities. We apply the metrics to study the Middle East and North Africa (MENA)-a region where science and technology capacity will play a key role in national economic diversification. We analyze 9.8 million publication records between 1981-2013 in 17 countries of MENA from Morocco to Iraq and compare it to selected countries throughout the world. The results show that international collaborators increasingly drove the scientific activity in MENA. The median indigeneity reached 52% in 2013 (indicating that almost half of the corresponding authors were located in foreign countries). Additionally, the regional disciplinary focus in chemical and petroleum engineering is waning with modest growth in the life sciences. We find repeated

    Full Text Available Introduction: Cleft lip and palate are among the most common congenital anomalies worldwide. This study was conducted in order to explore the incidence and related factors of cleft lip and/or palate (CL/P among live births in Mashhad, North-Eastern Iran.   Materials and Methods: In this cross-sectional study, records of 28,519 infants born between March 1982 and March 2011 at three major hospitals in Mashhad were screened for oral clefts. Clinical and demographic factors relating to diagnosed cases, including birth date, gender, birth weight, maternal age, number of pregnancies, type and side of cleft and presence of other congenital anomalies were recorded for analysis.   Results: The overall incidence of CL/P was 1.9 per 1,000 live births. Cleft lip associated with cleft palate (CLP was the most prevalent type of cleft (50%, followed by isolated cleft lip         (35.2% and isolated cleft palate (14.8%. A total of 92.6% of oral clefts were bilateral and 5.5% were located on the right side. In addition, clefts were found to be more common in male than female births (male/female ratio=2.3. The rate of associated congenital anomalies in CL/P newborns was 37%. No significant differences were observed in the incidence of oral clefts across three decades of study; except for CLP which was significantly more prevalent between 2002–2011 (P=0.027. There were no significant differences with regard to season of birth, associated anomalies or maternal age of affected newborns in the three time periods of the study. Furthermore, maternal age and number of pregnancies were not significantly different among the three types of cleft (P=0.43 and P=0.91, respectively. Although the mean birth weight of patients affected with isolated cleft palate was considerably lower than that of the other two types of cleft, the difference was not statistically significant (P=0.05.    Conclusion:  This study indicates a frequency of CL/P close to the findings

    In Antarctica, a reasonable coverage of ice core records exist for the last couple of hundred years, however there is poor spatial coverage of high-resolution climate data over the last 2000 years, particularly from East Antarctica (EA). The aim of the Aurora Basin North (ABN) ice core drilling project is to provide a 2000 year climate record from a data sparse area of EA to add to the IPICS 2k array and the PAGES Antarctica2k projects. ABN is a 303m ice core from EA, 550km inland and about half way between the coastal Law Dome and inland Dome C sites. Contiguous measurements of water stable isotope ratios (d18O and dD) have been performed along the entire length of the ABN ice core and provides a climate record at seasonal to decadal resolution for this region of EA spanning the past 2000 years. The isotopic variability at ABN shows clear annual cycles in the upper 50 m and longer-term variability on decadal to centennial timescales. The ABN record shows no long-term isotopic trend over the 2,000 year record length, similar to the four isotopic ice core records used in EA for the PAGES Antarctic 2k temperature reconstruction (PAGES2k, 2013). Mean ABN isotopic values (d18O -40.70 per mille, and dD -321.1 per mille) fall along the modern Antarctic spatial isotope/elevation and isotope/distance from the ocean relationships. The second order isotope parameter, deuterium excess (d) displays a relatively stable record (mean value of 4.4 per mille), with occasional sharp transitions to values as high as 8-10 per mille and as low as 0-1 per mille =. The large deuterium excess variations may reflect changes in moisture origin and evaporation conditions (SST, relative humidity). The isotopic variability at ABN therefore potentially reflects a mix of changes in transport and local climate (acting on precipitation intermittency and distillation strength), as well as local elevation changes. A comparison of the preliminary dated ABN isotope record with the Law Dome isotopic

    The use of Ni and Cu isotopes for tracing contamination sources in the environment remains a challenging task due to the limited information about the influence of various biogeochemical processes influencing stable isotope fractionation. This work focuses on a relatively simple system in north-east Norway with two possible endmembers (smelter-bedrock) and various environmental samples (snow, soil, lichens, PM 10 ). In general, the whole area is enriched in heavy Ni and Cu isotopes highlighting the impact of the smelting activity. However, the environmental samples exhibit a large range of δ 60 Ni (-0.01 ± 0.03‰ to 1.71 ± 0.02‰) and δ 65 Cu (-0.06 ± 0.06‰ to -3.94 ± 0.3‰) values which exceeds the range of δ 60 Ni and δ 65 Cu values determined in the smelter, i.e. in feeding material and slag (δ 60 Ni from 0.56 ± 0.06‰ to 1.00 ± 0.06‰ and δ 65 Cu from -1.67 ± 0.04‰ to -1.68 ± 0.15‰). The shift toward heavier Ni and Cu δ values was the most significant in organic rich topsoil samples in the case of Ni (δ 60 Ni up to 1.71 ± 0.02‰) and in lichens and snow in the case of Cu (δ 65 Cu up to -0.06 ± 0.06‰ and -0.24 ± 0.04‰, respectively). These data suggest an important biological and biochemical fractionation (microorganisms and/or metal uptake by higher plants, organo-complexation etc.) of Ni and Cu isotopes, which should be quantified separately for each process and taken into account when using the stable isotopes for tracing contamination in the environment.

    Full Text Available Vegetation biomass production in North-East India within Indo-Burma biodiversity hotspot is luxuriant and available from April to October to consider their potential for bioethanol production. Potential of six lignocellulosic biomass (LCB sources; namely, sugarcane bagasse (BG, cassava aerial parts (CS, ficus fruits (Ficus cunia (FF, “phumdi” (floating biomass, rice straw (RS, and sawdust were investigated for bioethanol production using standard techniques. Morphological and chemical changes were evaluated by Scanning electron microscopy and Fourier transform infrared spectroscopy and quantity of sugars and inhibitors in LCB were determined by High performance liquid chromatography. Hydrothermally treated BG, CS, and FF released 954.54, 1,354.33, and 1,347.94 mg/L glucose and 779.31, 612.27, and 1,570.11 mg/L of xylose, respectively. Inhibitors produced due to effect of hydrothermal pretreatment ranged from 42.8 to 145.78 mg/L acetic acid, below detection level (BDL to 17.7 µg/L 5-hydroxymethylfurfural, and BDL to 56.78 µg/L furfural. The saccharification efficiency of hydrothermally treated LCB (1.35–28.64% was significantly higher compared with their native counterparts (0.81–17.97%. Consolidated bioprocessing of the LCB using MTCC 1755 (Fusarium oxysporum resulted in maximum ethanol concentration of 0.85 g/L and corresponded to 42 mg ethanol per gram of hydrothermally treated BG in 120 h followed by 0.83 g/L corresponding to 41.5 mg/g of untreated CS in 144 h. These ethanol concentrations corresponded to 23.43 and 21.54% of theoretical ethanol yield, respectively. LCB of CS and FF emerged as a suitable material to be subjected to test for enhanced ethanol production in future experiments through efficient fermentative microbial strains, appropriate enzyme loadings, and standardization of other fermentation parameters.

    Full Text Available BACKGROUND Alcohol is the most commonly abused drug worldwide causing liver injury with respect to dose, duration, type of alcohol consumption and drinking patterns and gender with diverse ethnicity and social customs. There is high prevalence of alcohol use in the society without much social taboo in the North Eastern States of India and also there is a high prevalence of different ethnic tribes with the custom of taking country made alcohol casually as a part of their tradition. The aim of this study is to study the clinical profile of patients with alcoholic liver disease in upper Assam of north east India. MATERIALS AND METHODS The study was a hospital-based observational study in which patients of 18 years and older and diagnosed to have alcoholic liver disease were included. Cases excluded were patients of NASH, viral hepatitis, drug-induced hepatitis, haemochromatosis, alcoholic liver disease with diabetes and kidney disease. Informed written consent was taken from the patients or their attendants. Ethical clearance was taken from the Institutional Ethical Committee. A total of 138 cases were selected for the study. A detailed evaluation of clinical history, examination and investigations and the results were recorded in a predesigned proforma.

    Challenging greenhouse gas (GHG) emission reduction targets were set in Scotland by the Climate Change (Scotland) Act in June 2009. The national objective is to reduce GHG emissions by 42% by 2020 and 80% by 2050 compared to 1990 levels. The GHG emission reduction targets apply both to the traded and non-traded sectors, thus including the rural land use sector. In North East Scotland, rural land uses cover the majority of the land area, with agriculture and forestry representing about 86% and sporting land about 10% of the total area. The objectives of this study were to provide guidance for the development of a regional GHG inventory to estimate methane (CH 4 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) emissions from rural land uses in North East of Scotland, to compare with that of the United Kingdom (UK), and discuss the advantages of regional GHG inventories for rural land uses. The study mainly followed the guidance of the IPCC (Intergovernmental Panel on Climate Change) Revised Guidelines for National Greenhouse Gas Inventories and adapts these to the region level. Data available for North East Scotland allowed an assessment of annual GHG emissions from livestock and grassland, cropland management and sporting land, as well as carbon sequestered by forests, between 1999 and 2010. Estimated GHG emissions of 1420 ktCO 2 e from livestock, grassland and cropland management obtained in this study for 2009 compare well with estimates for the same region from larger-scale inventories. The methodology described, including the steps undertaken for data collection, the shortcomings found and strategies to overcome these, could be applied to other UK or European regions.

    Childhood obesity is one of the most serious public health issues of the twenty-first century affecting even low- and middle-income countries. Overweight and obese children are more likely to stay obese into adulthood. Due to the paucity of data on local practices, our study aimed to assess the knowledge and practices of physicians from the Middle East and North Africa region with respect to early-onset obesity. A specific questionnaire investigating the perception and knowledge on early-onset obesity was circulated to healthcare providers (general physicians, pediatricians, pediatric gastroenterologist, neonatologists) practicing in 17 Middle East and North African countries. A total of 999/1051 completed forms (95% response) were evaluated. Of all respondents, 28.9% did not consistently use growth charts to monitor growth during every visit and only 25.2% and 46.6% of respondents were aware of the correct cut-off criterion for overweight and obesity, respectively. Of those surveyed, 22.3, 14.0, 36.1, 48.2, and 49.1% of respondents did not consider hypertension, type 2 diabetes, coronary heart disease, fatty liver disease, and decreased life span, respectively, to be a long-term complication of early childhood obesity. Furthermore, only 0.7% of respondents correctly answered all survey questions pertaining to knowledge of early childhood overweight and obesity. The survey highlights the low use of growth charts in the evaluation of early childhood growth in Middle East and North Africa region, and demonstrated poor knowledge of healthcare providers on the short- and long-term complications of early-onset obesity. This suggests a need for both continued professional education and development, and implementation of guidelines for the prevention and management of early childhood overweight and obesity.

    Surface ozone is a greenhouse gas and pollutant detrimental to human health and crop and ecosystem productivity. The Tropospheric Ozone Assessment Report (TOAR) is designed to provide the research community with an up-to-date observation-based overview of tropospheric ozone's global distribution and trends. The TOAR Surface Ozone Database contains ozone metrics at thousands of monitoring sites around the world, densely clustered across mid-latitude North America, western Europe and East Asia. Calculating regional ozone trends across these locations is challenging due to the uneven spacing of the monitoring sites across urban and rural areas. To meet this challenge we conducted a spatial and temporal trend analysis of several TOAR ozone metrics across these three regions for summertime (April-September) 2000-2014, using the generalized additive mixed model (GAMM). Our analysis indicates that East Asia has the greatest human and plant exposure to ozone pollution among investigating regions, with increasing ozone levels through 2014. The results also show that ozone mixing ratios continue to decline significantly over eastern North America and Europe, however, there is less evidence for decreases of daytime average ozone at urban sites. The present-day spatial coverage of ozone monitors in East Asia (South Korea and Japan) and eastern North America is adequate for estimating regional trends by simply taking the average of the individual trends at each site. However the European network is more sparsely populated across its northern and eastern regions and therefore a simple average of the individual trends at each site does not yield an accurate regional trend. This analysis demonstrates that the GAMM technique can be used to assess the regional representativeness of existing monitoring networks, indicating those networks for which a regional trend can be obtained by simply averaging the trends of all individual sites and those networks that require a more

Materials and Methods: Initially, survey was conducted to identify and categorize the major housing patterns existing in the region for further detailed investigation. In total, 30 farmers/farms consisting of five housing types with six replicates were selected. Temperature and temperature humidity index (THI were recorded using the maximum-minimum thermometer and digital thermo-hygrometers. The study was conducted for 1 year covering four seasons namely South West monsoon (June-August, North East monsoon (September-November, cold season (December-February, and summer season (April-May. The data were statistically analyzed using statistical package SPSS 17. Results: Animal shelters with cement sheets recorded the highest temperature (26.71±1.13°C and THI (77.23±1.76 at 8.00 am, whereas the lowest temperature (24.83±1.17°C and THI (74.54±1.72 were recorded in the thatched shed. There was significant difference (p<0.01 in temperature and THI at 8.00 am during South West monsoon and North East monsoon seasons between the housing types. During cold and summer seasons, there was no significant difference (p≥0.05 in the environmental variables among various shelter systems. Conclusion: Thatched housing is found to be the suitable one with respect to the climatic variables, followed by tile roof and metal roof. The cement sheet roofed housing is found to be the most unsuitable one in the region for dairy cattle.

    Full Text Available Introduction: Over the past hundred years, human activity has significantly altered the atmosphere and increase of concentration of greenhouse gases lead to warm the earth's surface. This global warming leads to change of climatic extreme index and increases the intensity and frequency of occurrence of extreme climate events. Investigation of extreme values for planning and policy for the agricultural sector and water resource management is important.In this study, a comprehensive review of extreme indices of temperature and precipitation are discussed. This paper aims to investigate extreme temperature and precipitation indices defined in accordance with CCL, and the study of other climatic parameters in the North East of Iran. Materials and Methods: In this research, statistics and data of some stations in the North East of Iran during the period 1992-2012 were used. To evaluate the extreme climate indices trend, 27 indices of rainfall and temperature, were defined by the ETCCDMI. They were calculated by RClimdex software. In this software, prior to the index calculation, data by quality control software became quantitative and incorrect data were controlled and outlier data were examined. The indices were calculated by daily data. 11 rainfall and 16 temperature indices were calculated by this software.The target of the ETCCDMI process is to delineate a standardized set of indices allowing for comparison across regions. These extreme indices were classified in five categories which included the percentile-based extreme indices, the absolute extreme indices, the threshold extreme indices, the periodic extreme indices, and the other indices. They were estimated at the 0.05 significant levels. The Mann-Kendall test was used to investigate the climatic parameters, maximum relative humidity, sunshine duration and maximum wind speed. Results and Discussion: Thermal analysis results are consistent with warming patterns, and they have showed that hot

    Full Text Available Yields and production of rainfed areas in the Near East and North Africa are stagnating. The Australian wheat-medic system has been tried out in several countries of the region, Increases in soil fertility and yields were expected as well as better crop-livestock integration. Difficulties were more serious than foreseen. The farmer of the region differs from his Australian counterpart by the much smaller size of his farm and by his preference for keeping his land-use options open to match climatic variability.

    The MENA CSP (Middle East and North Africa - Concentrated Solar Power) plan is an ambitious scheme with an appeal to anyone concerned about climate change and convinced by the need for clean, renewable power. But what does it really mean for the average citizen of say Morocco or Tunisia? The World Bank sees potential for significant job and wealth creation in solar energy producing countries. If the CSP market grows rapidly over the next few years, equipment manufacturing will be essential to supply this new sector. This study proposes roadmaps and an action plan to help develop the potential of locally manufactured CSP components in the existing industry and for new market entrants.

    Full Text Available Abstract Background Nigeria's national standard has recently moved to artemisinin combination treatments for malaria. As clinicians in the private sector are responsible for attending a large proportion of the population ill with malaria, this study compared prescribing in the private and public sector in one State in Nigeria prior to promoting ACTs. Objective To assess prescribing for uncomplicated malaria in government and private health facilities in Cross River State. Method Audit of 665 patient records at six private and seven government health facilities in 2003. Results Clinicians in the private sector were less likely to record history or physical examination than those in public facilities, but otherwise practice and prescribing were similar. Overall, 45% of patients had a diagnostic blood slides; 77% were prescribed monotherapy, either chloroquine (30.2%, sulphadoxine-pyrimethamine (22.7% or artemisinin derivatives alone (15.8%. Some 20.8% were prescribed combination therapy; the commonest was chloroquine with sulphadoxine-pyrimethamine. A few patients (3.5% were prescribed sulphadoxine-pyrimethamine-mefloquine in the private sector, and only 3.0% patients were prescribed artemisinin combination treatments. Conclusion Malaria treatments were varied, but there were not large differences between the public and private sector. Very few are following current WHO guidelines. Monotherapy with artemisinin derivatives is relatively common.

  20. Distribution and conservation of three important bird groups of the Atlantic Forest in north-east Brazil

    G. A. Pereira

    Full Text Available Abstract The Pernambuco Endemism Center in north-east Brazil has the most fragmented forest cover and the largest number of threatened birds of the whole Atlantic Forest. We analyzed the distribution of three groups of bird species: forest-dependent, endemic and/or threatened using the interpolation method of Inverse Distance Weighting. We also checked the concentration of these birds in protected and unprotected areas, suggesting new sites that need to be protected. The richness concentration of forest-dependent, endemic and/or threatened birds in 123 sites were analysed. There was a greater concentration of the three groups in north Alagoas, south and north Pernambuco, and north and west Paraíba. The distribution of the three groups was almost regular in different vegetation types, although a lower concentration was found in the pioneer formation. There was a greater concentration of birds from all three groups between Pernambuco and Alagoas, and this must be due to the presence of more forest fragments with better structure and vegetation heterogeneity. The protected and unprotected areas hosted important records of endemic and/or threatened birds. We suggested some important places for implementation of new protected areas due to the larger concentrations of the target birds and because they are located within the boundaries of the Important Bird Areas.

    The NEA Co-ordinated Research and Environmental Surveillance Programme (CRESP) related to sea disposal of radioactive waste was started in 1981 following a recommendation of the Group of experts convened every five years by NEA to review the continued suitability of the dumping site for radioactive waste in the North-East Atlantic. The objective of CRESP is to increase the available scientific data base related to the oceanographic and biological characteristics of the dump site and elaborate a site specific model of the transfers of radionuclides to human populations. Volume one of the ''Interim Oceanographic Description of the North-East Atlantic Site for the Disposal of Low-Level Radioactive Waste'' was published in early 1983. It was an attempt to identify remaining gaps in current knowledge of conditions at the site and relate these conditions to the physical environment of the North-East Atlantic Ocean as a whole. The amount of data obtained by the CRESP Programme is now sufficient to justify publication of this second volume. Scientists present results of research which is of direct relevance to a better assessment of the impact from dumping radioactive waste in the North-East Atlantic, in particular an evaluation of the potential radiation doses to man. These two volumes represent part of the scientific contribution of the CRESP Programme to the 1985 Review of the Continued Suitability of the North-East Atlantic dump site

    The purpose of this study is to model the migration of hydrocarbon using Geographic Information System (GIS). Understanding hydrocarbon migration is important since it can mean the difference between success and failure in oil and gas exploration project. The hydrocarbon migration modeling using geophysical method is still not accurate due to the limitations of available data. In recent years, GIS has emerged as a powerful tool for subsurface mapping and analysis. Recent studies have been carried out about the abilities of GIS to model hydrocarbon migration. Recent advances in GIS support the establishment and monitoring of prediction hydrocarbon migration. The concept, model, and calculation are based on the current geological situation. The spatial data of hydrocarbon reservoirs is determined by its geometry of lithology and geophysical attributes. Top of Group E horizon of north-east Malay basin was selected as the study area due to the occurrence of hydrocarbon migration. Spatial data and attributes data such as seismic data, wells log data and lithology were acquired and processed. Digital Elevation Model (DEM) was constructed from the selected horizon as a result of seismic interpretation using the Petrel software. Furthermore, DEM was processed in ArcGIS as a base map to shown hydrocarbon migration in north-east Malay Basin. Finally, all the data layers were overlaid to produce a map of hydrocarbon migration. A good data was imported to verify the model is correct.

    2003-01-01

    In 1991, the G. Bush administration decided to remove away all US surface tactic nuclear weapons everywhere in the world in order to reduce the nuclear warfare risk. This decision has led to the ratification by both Northern Korea and Southern Korea of the declaration on the denuclearization of the Korean peninsula, followed the same year by Mongolia which has become nuclear weapons free. As a consequence of these initiatives, the Center for international strategy, technology and policy (CISTP) of the Georgia institute of technology (Atlanta, USA) has decided the creation of a 'limited nuclear weapons free zone North-East Asia'(LNWFZ), based on cooperation, arms control and non-proliferation. This article describes the genesis of this inter-governmental process of informal diplomacy: proposal of creation of a league for non-nuclear states for North-East Asia, of implementation of an inspection regime and of a cooperative security community, of establishment of confidence building measures and of economic incentives. Then it describes the main components of the LNWFZ project and the obstacles that must be cleared away before its official implementation. (J.S.)

    Optimized allocation of water resources is the important means of solving regional water shortage and can improve the utilization of water resources. Water resources allocation in the large-scale water diversion project area is the current research focus. This research takes the east route of the South-to-North Water Transfer Project in Jiangsu province as the research area, based on the hydrological model, agricultural irrigation quota model, and water project scheduling model, a water resources allocation model was constructed. The research carried on generalized regional water supply network, simulated the water supply, water demand and water deficit in agriculture, industry, life, ecology and lock under the status quo and planning engineering conditions. According to the results, the east route of the South-to-North Water Transfer Project is helpful to improve regional water shortage situation. The results showed that pump output increase by 2.8 billion cubic meters of water. On the conditions of P = 95%, 75% and 50%, compared with the benchmark year, water demand increases slightly due to the need of social and economic development in planning years, and water supply increased significantly because of new diversion ability. Water deficit are greatly reduced by 74.9% especially in the commonly drought condition because of the new project operation and optimized allocation of water resources.

    Full Text Available In the age of globalisation and continuous urbanisation, architects have a greater responsibility to design residential buildings with comfortable and sustainable environments. However, sustainable solutions should not concern themselves only with utilising technology, but also with creating synergies amongst a community’s social, cultural, historical, and environmental aspects. This research focuses on the implications of this wider definition of sustainability within the hot-arid climates of the Middle East and North Africa. Most of the current high-rise residential buildings in these regions do not promote social cohesion as they have been constructed without consideration for local identity and lifestyle. In contrast, vernacular courtyard dwellings and neighbourhoods offer good examples of socially cohesive and healthy environments. Yet, vernacular houses might not be compatible with pressures of modern construction. The question then becomes how to maintain the relationship between the spatial, social and environmental aspects while employing the latest technologies and materials. This paper presents the different qualities of vernacular houses and neighbourhoods in the different regions of the Middle East and North Africa. Social and spatial relationships of different cases are assessed, through a typological analysis approach using a developed syntactic-geometric model, to trace the lifestyle and the cultural values of the society. The aim is a parametric exploration of appropriate sustainable solutions that facilitate the synergy of socio-climatic requirements, the well-being qualities of the residents, and the specifics of culture, time and people while designing sustainable high-rise developments.

    Some crops of important nutritive requirements have been collected from farmlands located in Bitsichi an old tin mining town in north central region of Nigeria. The food crops were analyzed in order to determine trace element concentrations level using Neutron Activation Analysis (NAA). The activity concentrations due to natural radionuclides in the food samples and soil samples collected within the root zone of the crops were also determined using gamma-ray spectrometry (GRS). The NAA results obtained showed higher concentration of Potassium among the essential elements in all the crops. Calcium concentration in both maize and Guinea corn was below detection limit and also Zn in Green beans, sweet potato and cassava. The trace elements; Sc, Hf, Sm, and Th, were below detection limit in all the crops except in Green beans. Rubidium (Rb) and lanthanum (La) were below detection limits only in Cabbage. The activity concentrations of the natural radionuclides in the food samples were found to vary between 83 and 129 Bq kg -1 for 40 K, 19 and 30 Bq kg -1 for 226 Ra and 27 to 41 Bq kg -1 for 232 Th. In the soil samples the activity concentrations varied between 177 and 271 Bq kg -1 for 40 K, 53 and 96 Bq kg -1 for 226 Ra and 73 to 176 Bq kg -1 for 232 Th. Results of activity concentration levels of the radionuclides obtained in similar crops collected for control measurements were found to be very low compared to those from the study area. The effective dose due to intake of the food crops considered in the study area was estimated based on the measured activity concentrations of 226 Ra and 232 Th in the food crops. It was found to vary between 0.01 mSv y -1 (Acha) and 1.35 mSv y -1 (Cassava) with a cumulative total dose estimated as 2.5 mSv y -1 . The mining activities in the area are seen to have 1 influenced the concentration of these trace elements and radionuclides in the food I crops. However, they are seen not to pose any serious internal health burden due to

  10. The East Atlantic - West Russia Teleconnection in the North Atlantic: Climate Impact and Relation to Rossby Wave Propagation

    Large-scale winter teleconnection of the East Atlantic - West Russia (EA-WR) over the Atlantic and surrounding regions is examined in order to quantify its impacts on temperature and precipitation and identify the physical mechanisms responsible for its existence. A rotated empirical orthogonal function (REOF) analysis of the upper-tropospheric monthly height field captures successfully the EA-WR pattern and its interannual variation, with the North Atlantic Oscillation as the first mode. EA-WRs climate impact extends from eastern North America to Eurasia. The positive (negative) EA-WR produces positive (negative) temperature anomalies over the eastern US, western Europe and Russia east of Caspian Sea, with negative (positive) anomalies over eastern Canada, eastern Europe including Ural Mountains and the Middle East. These anomalies are largely explained by lower-tropospheric temperature advections. Positive (negative) precipitation anomalies are found over the mid-latitude Atlantic and central Russia around 60E, where lower-level cyclonic (anticyclonic) circulation anomaly is dominant. The eastern Canada and the western Europe are characterized by negative (positive) precipitation anomalies.The EA-WR is found to be closely associated with Rossby wave propagation. Wave activity fluxes show that it is strongly tied to large-scale stationary waves. Furthermore, a stationary wave model (SWM) forced with vorticity transients in the mid-latitude Atlantic (approximately 40N) or diabatic heat source over the subtropical Atlantic near the Caribbean Sea produces well-organized EA-WR-like wave patterns, respectively. Sensitivity tests with the SWM indicate improvement in the simulation of the EA-WR when the mean state is modified to have a positive NAO component that enhances upper-level westerlies between 40-60N.

    To evaluate the usefulness of simple screening tests such as urinalysis and blood pressure measurement in the early detection of renal disorders in pre-School children, we used a multi-staged random sampling method to select subjects from registered nursery schools within Enugu metropolis in south-east Nigeria. We selected 630 children for this cohort study. There was a prevalence of 2.7%, 0% and 1.9% for asymptomatic proteinuria, hematuria and hypertension, respectively. There was no age, gender or social class preponderance (P = 0.44). Hypertension seemed to be limited to children close to the age group of five years (P <0.001). No correlations could be documented between asymptomatic proteinuria, hematuria or hypertension. The prevalence of persistent proteinuria was found to be 1.6% and the mean urinary protein excretion estimation (spot urine protein/creatinine) was 1.88 g/mg ± 0.53, with a mean glomerular filtration rate of 78.7 ± 12.6 mL/min/1.73 m³ . Renal ultrasonography revealed abnormal findings in 30% of the children with persistent proteinuria. Asymptomatic persistent proteinuria with or without hematuria and hypertension could be a presumptive evidence of an underlying renal parenchymal disease and should be properly investigated and followed-up.

    Obesity and overweight are emerging major health problems in developing countries in the background of undernutrition. These have been linked to a substantial increase in mortality and morbidity. This cross-sectional survey was aimed at determining the prevalence of underweight, overweight, and obesity using body mass index (BMI) in primary school pupils in Abakaliki metropolis of Ebonyi State, south-east Nigeria. Eight hundred and four participants aged 6-12 years, from four public and four private primary schools had their weights and heights measured using standard methods. BMI value was calculated for each subject and compared with BMI for age and sex from World Health Organisation (WHO 2007) reference standard. Socioeconomic status was determined using method proposed by Oyedeji. Out of 804 subjects, 426 (53.0%) were from public schools, whereas 378 (47%) were from private schools (P ≤ 0.01). Four hundred and fifteen (51.6%) were males and 389 (48.4%) were female (P = 0.88). The prevalence of underweight, overweight, and obesity using BMI were 4.5% and 1.2%, 0% in public schools and 1.1%, 5.0%, and 3.0% in private schools, (P < 0.001). The socioeconomic class significantly affected the prevalence of underweight, overweight, and obesity as more subjects with overweight and obesity belonged to upper social class, whereas more underweight subjects belonged to lower social class. Overweight and obesity are emerging in a background of undernutrition, showing ''double burden'' of nutritional disorder.

    Spina bifida is a long-known disease arising from the incomplete fusion of the caudal neuropore in the first month of intrauterine life. It is thought to have a multifactorial etiology, the most important of which is folic acid deficiency. In evaluating its etiology, the role of antifolate agents like antimalarial drugs is rarely given a strong mention. This is a 44-month prospective study of consecutive cases of spina bifida cystica presenting to the Neurosurgery Unit of Nnamdi Azikiwe University Teaching Hospital, Nnewi, South-East Nigeria. Data collection was with a structured proforma from presentation, and collation done with Microsoft Excel broadsheet and data analysis with SPSS and χ2 test. A total of 41 cases of spina bifida were attended to within the period, with 92.7% cases of spina bifida cystica. Most presented by >12-24 months, with a consistent history of maternal ingestion of antimalarial drugs during the first trimester of pregnancy. Spina bifida cystica was diagnosed mostly in children whose mothers ingested antimalarial drugs during the first trimester of gestation. There may be a need to critically evaluate the contribution of antimalarial drugs to the etiopathogenesis of this malformation and develop safer antimalarial treatment in pregnancy.

    Full Text Available Nephila clavata L Koch, known as the Joro spider and native to East Asia (Japan, China, Korea, and Taiwan, is newly reported from North America. Specimens from several locations in northeast Georgia were collected from around residential properties in Barrow, Jackson, and Madison counties in late October and early November 2014. These are the first confirmed records of the species in the New World. Our collections, along with confirmed images provided by private citizens, suggest that the Joro spider is established in northeast Georgia. Genomic sequence data for the COI gene obtained from two specimens conforms to published sequences for N. clavata, providing additional confirmation of species identity. Known collection records are listed and mapped using geocoding. Our observations are summarized along with published background information on biology in Asia and we hypothesize on the invasion history and mode of introduction into North America. Recognition features are given and photographic images of the male and female are provided to aid in their differentiation from the one native species of the genus (Nephila clavipes in North America.

    Full Text Available The purpose of this article is to explain what are the key benefits and challenges of Social Media adoption and to underline the importance of Social Media for hotel industry. The importance of Internet in sales and promotion of tourism products is reflected in the figures of recent studies. Social Media represents a new form of communication between hotels and consumers. In tourism, one of the most popular topics for Social Media is to share your experience: writing reviews, post photos, videos and comments. This consumergenerated content is considered credible and unbiased. Hotel industry is facing a similar situation now with Social Media, as they were hesitating to create a website. One of the major errors is that hotels do not respond to social media posts. We assessed the presence and visibility of each 84 hotels on the three major Social Media channels (namely Facebook, Twitter and YouTube at the end of the year 2014. Where the official presence was not immediately found (usually the visitor is redirected from the official website, the first three pages search results were examined to try to establish the hotels official Facebook/Twitter/YouTube account. We carried out content analysis off all hotel Social Media accounts categorized between 3 to 5 stars in the North-East Region of Romania. Following our analysis, it was observed that North-East’s hotel units own in a 95% proportion an online presence. We cannot say the same thing about their presence on the Social Media platform. Surprisingly, most of the hotels we have analyzed have a functional website, 80 out of 84 hotels. We also noticed that the presence in Social Media is at the opposite pole (compared to the number of existing web pages, so that only 48 hotels have a Facebook page, 10 hotels have a Twitter account and 10 hotels have an YouTube account. Of the three networks we notice that Facebook is the most used network by hoteliers in the North-East region of Romania, Twitter

    Nigeria is still battling with preventable childhood deaths, being one of the six countries in which 50% of all global child deaths occur. Regular community and health facility audits are needed to determine morbidity and mortality patterns in children which will guide preventive and therapeutic interventions. The objective was to determine morbidity and mortality patterns, and identify factors influencing poor outcome of the disease in children seen in the emergency room of Nnamdi Azikiwe University Teaching Hospital, Nnewi. This was a 2-year retrospective study (March 2012 to February 2014) involving all children admitted into the children emergency room (CHER). Information on the patients' biodata, diagnosis, and outcome were retrieved from the CHER doctors' log. Analysis was done using Microsoft Office Excel 2007 and Statistical Package for Social Sciences version 20. The total of 1964 patients were seen (1088 males, 845 females, 31 unspecified) with a male to female ratio of 1.3:1. Under-fives constituted 78.8% of the study population. Mean duration of illness before presentation was 18.71 ± 71.94 days. Malaria, diarrheal disease, and respiratory tract infections were the most common morbidities. Sepsis had the highest case fatality rate (CFR) and was the most common cause of death among the 247 patients that died - mortality rate of 12.6%. Most deaths were in under-fives (CFR = 13.9, χ2 = 25.553, P = 0.000), with 74.1% of the mortalities occurring within 24 h of presentation. Patients who presented within a day and those that presented in the 2 nd and 3 rd weeks of onset of symptoms had CFR of 6.4-15.2%, respectively. Infectious diseases remain a menace in our environment with the eventual outcome worsened by late presentation to an appropriate health facility. There is an urgent need to create public awareness on the need to seek prompt medical attention for sick children.

    Full Text Available Sweetpotato is cultivated in all the regions of Côte d’Ivoire for consumption and as a source of income. Only varieties with white or yellow flesh are grown. Production of nutritious orange-fleshed sweetpotato (OFSP is hampered by the lack of genetic resources and planting material. To evaluate and release OFSP varieties, on-farm demonstration tests were conducted with women farmer groups in Bondoukou, Nassian, Korhogo and Bondiali in the north and northeast Côte d’Ivoire. Six varieties- ‘Kabode’, ‘Kakamega7’ (‘Irene’, ‘Tacha’, ‘Bela Bela’, ‘Vita’ and TIB-440060-were evaluated in comparison with locally grown varieties. The on-farm demonstration was laid out in a randomised complete block design with replicated three times per location. Assessments were made on yield, disease and pests; and consumer preference on attractiveness of skin color and flesh of the root (fresh and boiled, taste, texture and starchiness. Results showed that introduced varieties have generally recorded higher yields than the local varieties: Yields of about 25 t/ha have been recorded on the sites. The best average yield of about 15 t/ha, was recorded for TIB-440060 and ‘Irene’ varieties. Farmers’ acceptance of OFSP varieties based on the attraction of their color, the dry matter content and taste was more than 90%. At the end of the sensory tests, ‘Irene’, which achieved the best compromise between all observed and measured parameters, was most appreciated and was the farmers’ first choice, followed by varieties TIB-440060 and ‘Bela bela’.

    The aim of this study was to identify the characteristics of individuals who formed exogamic marriages in the Friuli region (north-east Italy) during the second half of the 19th century. Logistic regression models were devised to measure the influence of the determinants of exogamic marriage, taking into account not only variables related to context but also spouses' economic, social and cultural characteristics. The determinants of exogamic marriage differ for men and women, and also vary by region due to differences in geographical mobility and size of the marriage market. The majority of exogamic spouses belong to one of two categories: either older individuals, often, especially in the case of men, with a previous marriage; or the upper social classes. © Cambridge University Press, 2011

    Intuitively, interannual spring temperature variability (STV) should influence the leaf-out strategies of temperate zone woody species, with high winter chilling requirements in species from regions where spring warming varies greatly among years. We tested this hypothesis using experiments in 215 species and leaf-out monitoring in 1585 species from East Asia (EA), Europe (EU) and North America (NA). The results reveal that species from regions with high STV indeed have higher winter chilling requirements, and, when grown under the same conditions, leaf out later than related species from regions with lower STV. Since 1900, STV has been consistently higher in NA than in EU and EA, and under experimentally short winter conditions NA species required 84% more spring warming for bud break, EU ones 49% and EA ones only 1%. These previously unknown continental-scale differences in phenological strategies underscore the need for considering regional climate histories in global change models. © 2017 John Wiley & Sons Ltd/CNRS.

  7. Improving the Quality and Quantity of HIV Data in the Middle East and North Africa: Key Challenges and Ways Forward

    Full Text Available Although the HIV pandemic is witnessing a decline in the number of new infections in most regions of the world, the Middle East and North Africa (MENA has a rapidly growing HIV problem. While generating HIV data has been consistently increasing since 2005, MENA’s contribution to the global HIV literature is just over 1% and the existing evidence often falls behind the academic standards. Several factors could be at play that contribute to the limited quantity and quality of HIV data in MENA. This editorial tries to explore and explain the barriers to collecting high-quality HIV data and generating precise estimates in MENA. These barriers include a number of logistic and socio-political challenges faced by researchers, public health officials, and policy-makers. Looking at successful regional HIV programs, we explore examples were policies have shifted and lessons could be learned in developing appropriate responses to HIV across the region.

    HIV/AIDS and hepatitis C among people who inject drugs are on the rise in the Middle East and North Africa (MENA) region. But the regional response to the epidemic falls short both in terms of the quality and scale of response. From the threat of the death sentence for drug offenses to the burden of refugees fleeing conflict, there are many legal, political and social barriers that hinder the introduction and expansion of harm reduction in the region. However Iran and Morocco are two pioneering countries and over the last decade they have been providing evidence that harm reduction is feasible and acceptable in MENA. Using different approaches, these two countries have overcome various obstacles and encouraged discussion and collaboration among stakeholders, including government, health professionals, civil society and community-based organizations. In so doing they have created an enabling environment to endorse a national harm strategy. Copyright © 2016 Elsevier B.V. All rights reserved.

    Weather forecasting is an important issue in the field of meteorology all over the world. The pattern and amount of rainfall are the essential factors that affect agricultural systems. India experiences the precious Southwest monsoon season for four months from June to September. The present paper describes an empirical study for modeling and forecasting the time series of Southwest monsoon rainfall patterns in the North-East India. The Box-Jenkins Seasonal Autoregressive Integrated Moving Average (SARIMA) methodology has been adopted for model identification, diagnostic checking and forecasting for this region. The study has shown that the SARIMA (0, 1, 1) (1, 0, 1)4 model is appropriate for analyzing and forecasting the future rainfall patterns. The Analysis of Means (ANOM) is a useful alternative to the analysis of variance (ANOVA) for comparing the group of treatments to study the variations and critical comparisons of rainfall patterns in different months of the season.

    2017-11-01

    Full Text Available A number of recent novels have chosen to variously address the existing conditions of the multi-ethnic mosaic of the Indian North-East. These works of fiction shed light upon a dramatic contemporary condition and propound an alternative historical archive able to perturb the current image of India as a neo-liberal, globalized super power. Indeed, in India’s complex, uneven and contradictory patterns of economic and technological progress, perspectives of development prove highly controversial. In Surface, a novella written in 2005 by Siddhartha Deb, set in the Northeastern region and seemingly modeled upon Conrad’s colonial archetype Heart of Darkness, a post-millennial social community of investors, executives, administrators, traders, politicians, journalists, social workers and rebels, inhabit a very complex, and ‘dark’, territorial reality.

    In this study, mineral magnetic properties and petroleum hydrocarbons were statistically analysed in four sediment cores (C1, A1, T1 and K1) from the north east coast of Tamilnadu, India to examine the feasibility of PHC concentrations assessment using magnetic susceptibility. The C1 and A1 cores reveal a clear horizon of increase in PHC above 35 and 50 cm respectively suggesting the excess anthropogenic loading occurred in the recent past. Magnetic properties which were enhanced in the upper part of the sediment cores were the result of ferrimagnetic minerals from anthropogenic sources. Factor analysis confirmed that the input of magnetic minerals and petroleum hydrocarbons in Chennai coastal sediments are derived from the same sources. The present study shows that instead of expensive and destructive PHC chemical methods, magnetic susceptibility is found to be a suitable, cheap and rapid method for detailed study of petroleum hydrocarbon contamination in marine sediments.

    Natural hazards have a potentially large impact on economic growth, but measuring their economic impact is subject to a great deal of uncertainty. The central objective of this paper is to demonstrate a model--the natural disasters vulnerability evaluation (NDVE) model--that can be used to evaluate the impact of natural hazards on gross national product growth. The model is based on five basic indicators-natural hazards growth rates (αi), the national natural hazards vulnerability rate (ΩT), the natural disaster devastation magnitude rate (Π), the economic desgrowth rate (i.e. shrinkage of the economy) (δ), and the NHV surface. In addition, we apply the NDVE model to the north-east Japan earthquake and tsunami of March 2011 to evaluate its impact on the Japanese economy. © 2014 The Author(s).

    Despite the importance of the nutritional status and food systems of Indigenous Peoples, the subject has received very little attention, especially in North-East India. Therefore, a community-based cross-sectional descriptive study was carried out among Chakhesang mothers with children under 5 years of age to evaluate their nutritional status and prevalence of chronic diseases in the context of their dietary habits. From 558 households (HHs), 661 children and 540 mothers were covered using standard anthropometric measurements as well as blood collection for haemoglobin and vitamin A. Data were collected from mothers on HH socio-demographic particulars and infant and young child feeding practices. The results showed that the prevalence of underweight, stunting, and wasting among children security among the Chakhesangs. © 2018 John Wiley & Sons Ltd.

    Breast cancer is the most frequent cause of cancer death in women worldwide, but global disparities in breast cancer control persist, due to a lack of a comprehensive breast cancer control strategy in many countries. To identify and compare the need for breast cancer control strategies in Asia, Latin America and the Middle East/North Africa and to develop a common framework to guide the development of national breast cancer control strategies. Data were derived from open-ended, semi-structured interviews conducted in 2007 with 221 clinicians, policy makers, and patient advocates; stratified across Asia (n = 97), Latin America (n = 46), the Middle East/North Africa (ME/NA) (n = 39) and Australia and Canada (n = 39). Respondents were identified using purposive and snowballing sampling. Interpretation of the data utilized interpretive phenomenological analysis where transcripts and field notes were coded and analyzed and common themes were identified. Analysis of regional variation was conducted based on the frequency of discussion and the writing of the manuscript followed the RATS guidelines. Analysis revealed four major themes that form the foundation for developing national breast cancer control strategies: 1) building capacity; 2) developing evidence; 3) removing barriers; and 4) promoting advocacy - each specified across five sub-ordinate dimensions. The propensity to discuss most dimensions was similar across regions, but managing advocacy was discussed more frequently (p = 0.004) and organized advocacy was discussed less frequently (p < 0.001) in Australia and Canada. This unique research identified common themes for the development of breast cancer control strategies, grounded in the experience of local practitioners, policy makers and advocacy leaders across diverse regions. Future research should be aimed at gathering a wider array of experiences, including those of patients.

    Prevalence of adolescent sexual activity is on the increase globally, resulting in increased risk of adverse reproductive health outcomes among them. Sources of sex information are key factors that influence female adolescents' sexual decision-making. Consequently, this study is aimed at identifying adolescents' sources of sexuality information, and its likely effect on their sexual practices among in-school female adolescents in Osisioma LGA, in southeastern Nigeria. A total of 304 girls selected by multi-stage sampling technique were studied. Responses were elicited from them using pretested, semi-structured, self administered questionnaire. Data were analyzed using MS Excel and Epi-6. Primary and subsequent sources of sexuality information were mainly the media and peers. Families and schools mostly were not involved in provision of early sex education. Media and peer influence were predominantly negative. Female adolescents' knowledge of issues of sex was low. Premarital sex, early sexual initiation, and unprotected sex was common among them. Consequently, adverse implication of negative sexual behavior, such as unplanned pregnancies and induced abortion, was prevalent. The study highlights the need for increased roles of parents and teachers in early sexuality education of adolescent girls. This can be done by increasing capacity of parents to discuss sexuality issues with their children. Copyright © 2011 North American Society for Pediatric and Adolescent Gynecology.

    The continental shelf of central-east Greenland is shaped by several glacially carved transverse troughs that form the oceanward extension of the major fjord systems. The evolution of these troughs through time, and their relation with the large-scale glaciation of the Northern Hemisphere, is poorly understood. In this study seismostratigraphic analyses have been carried out to determine the morphological and structural development of this important sector of the East Greenland glaciated margin. The age of major stratigraphic discontinuities has been constrained by a direct tie to ODP site 987 drilled in the Greenland Sea basin plain off Scoresby Sund fan system. The areal distribution and internal facies of the identified seismic units reveal the large-scale depositional pattern formed by ice-streams draining a major part of the central-east Greenland ice sheet. Initial sedimentation along the margin was, however, mainly controlled by tectonic processes related to the margin construction, continental uplift, and fluvial processes. From late Miocene to present, progradational and erosional patterns point to repeated glacial advances across the shelf. The evolution of depo-centres suggests that ice sheet advances over the continental shelf have occurred since late Miocene, about 2 Myr earlier than previously assumed. This cross-shelf glaciation is more pronounced during late Miocene and early Pliocene along Blosseville Kyst and around the Pliocene/Pleistocene boundary off Scoresby Sund; indicating a northward migration of the glacial advance. The two main periods of glaciation were separated by a major retreat of the ice sheet to an inland position during middle Pliocene. Mounded-wavy deposits interpreted as current-related deposits suggest the presence of changing along-slope current dynamics in concert with the development of the modern North Atlantic oceanographic pattern.

    Continental slopes north of the East Siberian Sea potentially hold large amounts of methane (CH4) in sediments as gas hydrate and free gas. Although release of this CH4 to the ocean and atmosphere has become a topic of discussion, the region remains sparingly explored. Here we present pore water chemistry results from 32 sediment cores taken during Leg 2 of the 2014 joint Swedish-Russian-US Arctic Ocean Investigation of Climate-Cryosphere-Carbon Interactions (SWERUS-C3) expedition. The cores come from depth transects across the slope and rise extending between the Mendeleev and the Lomonosov ridges, north of Wrangel Island and the New Siberian Islands, respectively. Upward CH4 flux towards the seafloor, as inferred from profiles of dissolved sulfate (SO42-), alkalinity, and the δ13C of dissolved inorganic carbon (DIC), is negligible at all stations east of 143° E longitude. In the upper 8 m of these cores, downward SO42- flux never exceeds 6.2 mol m-2 kyr-1, the upward alkalinity flux never exceeds 6.8 mol m-2 kyr-1, and δ13C composition of DIC (δ13C-DIC) only moderately decreases with depth (-3.6 ‰ m-1 on average). Moreover, upon addition of Zn acetate to pore water samples, ZnS did not precipitate, indicating a lack of dissolved H2S. Phosphate, ammonium, and metal profiles reveal that metal oxide reduction by organic carbon dominates the geochemical environment and supports very low organic carbon turnover rates. A single core on the Lomonosov Ridge differs, as diffusive fluxes for SO42- and alkalinity were 13.9 and 11.3 mol m-2 kyr-1, respectively, the δ13C-DIC gradient was 5.6 ‰ m-1, and Mn2+ reduction terminated within 1.3 m of the seafloor. These are among the first pore water results generated from this vast climatically sensitive region, and they imply that abundant CH4, including gas hydrates, do not characterize the East Siberian Sea slope or rise along the investigated depth transects. This contradicts previous modeling and discussions, which

    Full Text Available There is a general recognition of homosexuality being responsible for the high prevalence of HIV/AIDS among inmates in Nigerian prisons. However, the use of condoms which is an evidenced-based preventive measure is critical in the prison setting because of socio-cultural reasons. Due to the dynamic nature of the prison population, interventions targeting the prisons will have a significant effect on the general population. This study assessed condom acceptability for the prevention of HIV infection among male inmates in a convict prison in north-western, Nigeria in order to provide supplementary information that will corroborate some findings from quantitative methods. A qualitative study was conducted in Zaria prison between 18th December, 2012 and 8th January, 2013. Purposive sampling identified 48 inmates who had Focused Group Discussions (FGDs and In-depth Interviews (IDIs. Common trends and variations in the responses were identified and reflected as appropriate and presented as narratives with relevant quotations. Majority of the respondents agreed that homosexuality exists among the inmates, but all the inmates scowled at the distribution of condoms to inmates in prison. Majority were of the opinion that condom distribution will promote homosexuality which is prohibited by Nigerian laws and controlling HIV transmissions in Nigeria prisons can be effectively done through behavioral modifications that are geared towards total abstinence.

    The payment for health-care services is a major problem for many poor patients in developing nations. The aim of the study was to examine the cost of services and commodities and how these affect the patients who utilizes the primary health-care centers in Zaria, North western Nigeria. A descriptive cross-sectional survey of six primary health-care facilities in Zaria metropolis, namely Baban dodo, Tudun Wada, Magajiya PHCs from Zaria local government areas (LGA) and Samaru, Kwata, and Dogarawa PHCs from Sabon Gari LGA, was carried out. The mean age of the respondents was 28.87± 8.63 years, most of them were married (53.3%), Hausa (63.3%), and Muslims (85.7%); also, they were unemployed housewives with daily stipends from their husbands less than 1 dollar/day. The major method for payment for health-care services was out of pocket (98.3%). More than one-third of the clients were not aware of the National Health Insurance Scheme (NHIS) (39%). There was a significant inverse relationship between the monthly income of the clients and the experience of financial stress and a positive association between patients' monthly income and awareness of the NHIS (P commodities and the implementation of the National Health Act may alleviate the burdens of the poor community members who access PHCs in Nigeria.

    Full Text Available This study aimed at exploring the Effect of supply chain management on organizational performance of the Private manufacturing enterprises (PMEs in South-East. To do so, the study used a questionnaire survey of the views of staff of selected companies on the subject matter. Secondary sources including textbooks, journals, unpublished work and other materials that related to the concept were also used. A sample size of 553 was derived from a total population of 1124 using Freund and William’s statistical formula. In this study, the content validity was used. The respondents interviewed as well as experts were approached face to face. Cronbach’s Alpha was used to test the reliability of the research instrument showing a result of 0.91. Two hypotheses were tested using Pearson product moment correlation and Regression analysis. The main findings of the study showed that training, technological know-how and security of investments enhance the development of innovative skills; also, opportunity identification positively promotes research and development significantly. The study concluded and recommended that firms need to ensure that their entrepreneurial abilities are developed consistently so that their survival will be ensured. Also that indigenous firm should engage in employment of qualified staff, though within their budget capacity.

    Late tectonic, post-collisional granite suites are a feature of many parts of the Late Neoproterozoic to Cambrian East African Orogen (EAO), where they are generally attributed to late extensional collapse of the orogen, accompanied by high heat flow and asthenospheric uprise. The Maevarano Suite comprises voluminous plutons which were emplaced in some of the tectonostratigraphic terranes of northern Madagascar, in the central part of the EAO, following collision and assembly during a major orogeny at ca. 550 Ma. The suite comprises three main magmatic phases: a minor early phase of foliated gabbros, quartz diorites, and granodiorites; a main phase of large batholiths of porphyritic granitoids and charnockites; and a late phase of small-scale plutons and sheets of monzonite, syenite, leucogranite and microgranite. The main phase intrusions tend to be massive, but with variably foliated margins. New U-Pb SHRIMP zircon data show that the whole suite was emplaced between ca. 537 and 522 Ma. Geochemically, all the rocks of the suite are enriched in the LILE, especially K, and the LREE, but are relatively depleted in Nb, Ta and the HREE. These characteristics are typical of post-collisional granitoids in the EAO and many other orogenic belts. It is proposed that the Maevarano Suite magmas were derived by melting of sub-continental lithospheric mantle that had been enriched in the LILE during earlier subduction events. The melting occurred during lithospheric delamination, which was associated with extensional collapse of the East African Orogen. ?? 2009 Natural Environment Research Council.

    The field work of the north Atlantic monitoring Program (NOAMP) was supplemented by numerical simulations of the transport of radionuclides in the North Atlantic Ocean by annual mean flows and mixing processes. During the last year of NOAMP, a different attempt was made to compute the current field and three-dimensional trajectories of particles released in deep layers of the NOAMP area. It is the subject of this paper. The model used is of Bryan/Semtner type, but with smoothed topography and climatological (winter) temperature and salinity data. The results form a compromise between interpretation of climatological temperature and salinity data and the complete prediction of the current field by prognostic calculations, which yields a deep flow pattern that agrees with some ideas of the abyssal circulation

    Promoter hypermethylation is a common event in human cancer. O6-methylguanine-DNA methyltransferase (MGMT) is a gene involved in DNA repair, which is methylated in a variety of cancers. We aimed to explore the methylation status of MGMT gene among the North Eastern population where esophageal cancer incidence and exposure to carcinogens like nitrosamines is high. A total of 100 newly diagnosed esophageal cancer cases along with equal number of age, sex and ethnicity matched controls were included in this study. Methylation specific PCR was used to determine the MGMT methylation status in serum samples. Aberrant promoter methylation of the MGMT gene was detected in 70% of esophageal cancer cases. Hypermethylation of MGMT gene was found to be influenced by environmental factors like betel quid and tobacco which contain potent carcinogens like nitrosamines. Tobacco chewing and tobacco smoking habit synergistically with MGMT methylation elevated the risk for esophageal cancer development [adjusted OR=5.02, 95% CI=1.35-18.74; p=0.010 for tobacco chewing and Adjusted OR=3.00, 95% CI=1.22-7.36; p=0.014 for tobacco smoking]. Results suggest that the DNA hypermethylation of MGMT is an important mechanism for MGMT gene silencing resulting in esophageal cancer development and is influenced by the environmental factors. Thus MGMT hypermethylation can be used as a biomarker for esophageal cancer in high incidence region of North East India.

    The recent introduction of the macroalga Undaria pinnatifida (Harvey) Suringar into the North Atlantic is the latest of a large number of introductions, which have occurred over many years. Some have been deliberate introductions for mariculture or research, while most have been accidental, via vectors such as shipping and shellfish imports. Not all newly recorded species are introductions; some are thought to be merely extensions of distribution, e.g. Laminaria ochroleuca, while others may have been overlooked previously, e.g. Scytosiphon dotyi. Subsequent to its accidental introduction into the waters around the Mediterranean French coast at Sete, most likely with imported oysters, Undaria was deliberately introduced into the North Atlantic, to Brittany, in 1983 by IFREMER for commercial exploitation. Undaria has since spread from the original sites in Brittany, and is now established at several sites on the south coast of England. This paper discusses the introduced brown algae in the North Atlantic and outlines the establishment of Undaria in the UK.

    Allogeneic blood for transfusion is in short supply in most parts of the developing world. Cord blood for transfusion can be a significant source of blood supply to our health institutions. This study aims to investigate the knowledge and attitude to the donation and use of umbilical cord blood (UCB) for transfusion among the patients receiving services in a tertiary health institution in South-East Nigeria. This was a cross-sectional study; an anonymous structured questionnaire was used. A total of 549 consenting patients randomly selected from the antenatal, postnatal, sickle cell clinics, and wards were the subjects. Statistical analysis of the data was done using SPSS version 20.0. The mean age of the participants was 31.9 ± 9.5 years. The majority were females (77.2%), married (86.4%). About 26.2% of the respondents were willing to accept UCB for transfusion to them or their child. Following counseling, the acceptance rate increased to 71.5%. Most of the respondents (80.0%) were willing to donate the UCB of their baby; or be tested for HIV (93.3%), if necessary. Educational level was significantly associated with knowledge of UCB. After logistic regression, occupation, and gender were significantly associated with acceptance of UCB for transfusion. Up to 52% belonged to low income family background, approximately 150 US dollars monthly family income (50,000 naira). The knowledge and acceptance of UCB for transfusion are low in our environment. However, proper counseling and public enlightenment could change this attitude.

    Salinity occurs in the drier and flatter Australian landscapes because there is insufficient rain to flush salts from critical zone. Changes in land use due to agriculture and urbanisation can accelerate salinity effects, leading to soil and water degradation and threatening infrastructure and ecosystems. The dominant lithology in the salt affected regions of North-east Tasmania is dolerite. The geochemistry of dolerite regolith has been examined in order to understand the association between salinity and weathered dolerite. The electrical conductivity of 1:5 soil-waters is higher in the more weathered material (maximum 4.9 dS/m). This confirms field observations that highly weathered dolerite can serve as a significant store for salt in the landscape. However, the clay content and salinity varies, depending on the local geomorphic context. Dolerite weathering on well-drained slopes has favoured the formation of 1:1 kaolinite clays, and sometimes bauxite formation. Kaolinite-bearing regolith can store salt via matrix diffusion processes. However, there are fault-bounded pockets of colluvium and highly-weathered in situmaterial, where the supply of cations has not been diminished and 2:1 montmorillonite clays dominate. These regions have the capacity to store large volumes of salts. The geomorphology also affects the volume of rain and flux of salt from windblown dust and oceanic aerosols. The chemistry of rainwater from an array of bulk deposition collectors was studied from Spring 2013 to Winter 2014. The average salt flux was 79± 10 kg/ha/yr in the study region, ranging from 170± 12 kg/ha/yr in the north to 42 ± 6 kg/ha/yr inland. To assist in understanding why salt is found in certain parts of the landscape but not in others, it is essential to model how water moves through the critical zone and geological structures. By exploring the complex interactions of geomorphology and other biophysical parameters the study area has been divided into Hydrogeological

    Concentrations of tourmaline in Early Proterozoic metasedirnentary rocks of the Cuyuna iron range, east-central Minnesota, provide a basis for redefinition of the evolutionary history of the area. Manganiferous iron ore forms beds within the Early Proterozoic Trommald Formation, between thick-bedded granular iron-formation having shallow-water depositional attributes and thin-bedded, nongranular iron-formation having deeper water attributes. These manganese-rich units were previously assumed to be sedimentary in origin. However, a revaluation of drill core and mine samples from the Cuyuna North range has identified strata-bound tourmaline and tourmalinite, which has led to a rethinking of genetic models for the geology of the North range. We interpret the tourmaline-rich rocks of the area to be a product of submarine-hydrothermal solutions flowing along and beneath the sedirnent-seawater interface. This model for the depositional environment of the tourmaline is supported by previously reported mineral assemblages within the Trommald Formation that comprise aegirine; barium feldspar; manganese silicates, carbonates, and oxides; and Sr-rich barite veins. In many places, tourmaline-rich metasedimentary rocks and tourmalinites are associated locally with strata-bound sulfide deposits. At those localities, the tourmaline-rich strata are thought to be lateral equivalents of exhalative sulfide zones or genetically related subsea-floor replacements. On the basis of the occurrence of the tourmaline-rich rocks and tourmalinites, and on the associated minerals, we suggest that there is a previously unrecognized potential for sediment-hosted sulfide deposits in the Cuyuna North range.

    The Middle East is a region historically sensitive to climate variability and change, and contains snowpacks that have been shown to be important inputs to key regional water resources, including the Tigris-Euphrates river system. Focusing on the Middle East (and the smaller snowpacks of northwestern Africa), this presentation aims to (i) quantify each year's snowpack development and recession over recent decades, highlighting interannual to decadal variability, and (ii) advance understanding on the connection between the snowpack variations and aspects of regional hydrology. The presentation draws on satellite-based products, station data, and model reanalyses. Variation is summarized using space-time statistical techniques, as well as simpler regional indices: Northwestern Iran / Southern Caucasus (NWIC, includes Zagros Mountains); Eastern Turkey (ETKY, includes Taurus Mountains); and smaller scale indices for Lebanon and the Atlas Mountains. The Interactive Multisensor Snow and Ice Mapping System archives daily snow cover extent at 24 km resolution for 1999-present (primarily from visible satellite imagery). These data show that for both NWIC and ETKY, the mean snow extent peaks in late January with substantial coverage ( 300,000 km2 in each region), contracting to near zero by late June. A very large mid-winter interannual variance is also shown, implying substantial variation in hydrologic impacts during spring melt. Variability and decadal trends are compared with station snow depth reports (Global Historical Climatology Network - Daily). Strong agreement gives confidence in data quality, as well as, indicating high covariation of depth and extent. The connection with hydrologic impacts is investigated using reanalysis products, including the Global Land Data Assimilation System V2, which for the Middle East, shows broad agreement with observed maximum snow extent and spring retreat. The connections internal to the reanalysis between snow cover, melt and

    Environmental management in urban areas is difficult due to the amount and miscellaneous data needed for decision making. This amount of data is splendid without adequate database systems and modern methodologies. A geo-database building for East Cairo City Area (ECCA) is built to be used in the process of urban land-use suitability to achieve better performance compared with usual methods used. This Geo-database has required availability of detailed, accurate, updated and geographically referenced data on its terrain physical characteristics and its expected environmental hazards that may occur. A smart environmental suitability model for ECCA is developed and implemented using ERDAS IMAGINE 9.2. This model is capable of suggesting the more appropriate urban land-use, based on the existing spatial and non-spatial potentials and constraints.

    A review of Pap smear diagnoses from a reference laboratory in Grand Forks, North Dakota over a 3-year period (07/00 to 10/03) revealed a two-fold higher rate of high grade squamous intraepithelial lesion in a community in northwest Minnesota (Roseau, 0.486%) than in northeast North Dakota (Grand Forks, 0.249%), in spite of both having similar rates of low-grade squamous intraepithelial lesion (1.33% vs.1.30% respectively) To identify the different types of HPV present in patient populations showing high-grade dysplasia in Grand Forks, ND and Roseau, MN. Formaldehyde-fixed paraffin-embedded cervical tissue samples were analyzed using polymerase chain reaction (PCR) to detect the presence of HPV type 16, 18 and 31. Our studies showed that 41% of samples from Roseau were triply infected with HPV serotypes 16, 18 and 31 in comparison to 12 % from Grand Forks. Due to the small sample size we were unable to prove the study to be statistically significant. However, our results suggest that the presence of HPV 16, 18 and 31 in triply infected samples may be the cause of the higher percentage of high-grade dysplasia in Roseau, MN when compared to Grand Forks, ND.

    Full Text Available Microplastic contamination was determined in sediments of the Southern North Sea and floating at the sea surface of North West Europe. Floating concentrations ranged between 0 and 1.5 microplastic/m3, whereas microplastic concentrations in sediments ranged between 0 and 3,146 particles/kg dry weight sediment. In sediments, mainly fibers and spheres were found, whereas at the sea surface fragments were dominant. At the sea surface, concentrations of microplastics are lower and more variable than in sediments, meaning that larger sample sizes and water volumes are required to find detectable concentrations. We have calculated the widths of the confidence intervals (CI for different sample sizes, to give a first indication of the necessary sample size for a microplastic survey at the water surface. Higher concentrations of floating microplastics were found near estuaries. In sediments, estuaries and areas with a high organic carbon content were likely hotspots. Standardization of monitoring methods within marine regions is recommended to compare and assess microplastics pollution over time.

    Semi-arid areas are, due to their climatic setting, characterized by small water resources. An increasing water demand as a consequence of population growth and economic development as well as a decreasing water availability in the course of possible climate change may aggravate water scarcity in future, which often exists already for present-day conditions in these areas. Understanding the mechanisms and feedbacks of complex natural and human systems, together with the quantitative assessment of future changes in volume, timing and quality of water resources are a prerequisite for the development of sustainable measures of water management to enhance the adaptive capacity of these regions. For this task, dynamic integrated models, containing a hydrological model as one component, are indispensable tools. The main objective of this study is to develop a hydrological model for the quantification of water availability in view of environmental change over a large geographic domain of semi-arid environments. The study area is the Federal State of Ceará (150 000 km2) in the semi-arid north-east of Brazil. Mean annual precipitation in this area is 850 mm, falling in a rainy season with duration of about five months. Being mainly characterized by crystalline bedrock and shallow soils, surface water provides the largest part of the water supply. The area has recurrently been affected by droughts which caused serious economic losses and social impacts like migration from the rural regions. The hydrological model Wasa (Model of Water Availability in Semi-Arid Environments) developed in this study is a deterministic, spatially distributed model being composed of conceptual, process-based approaches. Water availability (river discharge, storage volumes in reservoirs, soil moisture) is determined with daily resolution. Sub-basins, grid cells or administrative units (municipalities) can be chosen as spatial target units. The administrative units enable the coupling of Wasa in

    The East Beni Sueif Basin is the only tested hydrocarbon-bearing basin on the eastern side of the Nile in Egypt. The basin is located around 150 km to the south of Cairo. This work introduces the first attempt of seismic interpretation and structural patterns of this basin, for which subsurface published works are lacking. Structural imaging of the area is achieved through interpretation of pre-stack time migration (PSTM) seismic cube and data sets of seven wells. The penetrated sedimentary section is represented by Albian-Middle Eocene sediments. The East Beni Sueif Basin is a type of the whole graben-system and is bounded by two NW-SE bounding faults. These faults had continued activity in an extensional regime associated with fault-propagating folds. The basin is traversed by a N75°E-trending fault system at basement level. This fault system separates the basin into two structural provinces. The Northwestern Province is deeper and shows more subsidence with a predominance of NW-trending longitudinal faults and N60·W oblique faults to the basin trend. The Southeastern Province is shallow and crossed by N14·W-trending faults which are slightly oblique to the basin axis. Albian time had witnessed the main extensional tectonic phase and resulted in major subsidence along basin-bounding faults associated with growth thickening of basal deposits. During Senonian time, the basin experienced a mild phase of transtensional tectonics, which formed negative-flower structures entrapping different folds along the N75°E and N60·W faults. The timing and style of these structures are similar to the Syrian-Arc structures in several Western Desert oil fields. The basin emerged during the Paleocene with scoured and eroded top Cretaceous sediments. Subsidence was resumed during the Early Eocene and resulted in 1500 m-thick carbonate sediments. Lastly, a mild extensional activity possibly occurred during the Oligocene-Miocene time. Despite the possible restricted potentiality

    Anopheles minimus is one of the major vectors for transmission of malaria disease in north eastern (NE) region of India. The minimus species complex of Minimus subgroup of Myzomyia series of anophelines were studied in malaria affected states--Assam and Arunachal Pradesh (AP) of NE India. Ribosomal DNA markers--second internal transcribed spacer (ITS2) and third domain (D3) of 28S gene were used to characterize An. minimus species. Sequence homogeneity was observed in D3 sequences of An.minimus specimens throughout both the states. However, a transversion in ITS2 sequence of single specimen collected from Assam-Meghalaya border areas illustrates possibility of intra population polymorphism in ITS2 sequence within the geographical region.

    Science.gov (United States)

    2012-01-01

    Background Tunisia is a North African country of 10 million inhabitants. The native background population is Berber. However, throughout its history, Tunisia has been the site of invasions and migratory waves of allogenic populations and ethnic groups such as Phoenicians, Romans, Vandals, Arabs, Ottomans and French. Like neighbouring and Middle Eastern countries, the Tunisian population shows a relatively high rate of consanguinity and endogamy that favor expression of recessive genetic disorders at relatively high rates. Many factors could contribute to the recurrence of monogenic morbid trait expression. Among them, founder mutations that arise in one ancestral individual and diffuse through generations in isolated communities. Method We report here on founder mutations in the Tunisian population by a systematic review of all available data from PubMed, other sources of the scientific literature as well as unpublished data from our research laboratory. Results We identified two different classes of founder mutations. The first includes founder mutations so far reported only among Tunisians that are responsible for 30 genetic diseases. The second group represents founder haplotypes described in 51 inherited conditions that occur among Tunisians and are also shared with other North African and Middle Eastern countries. Several heavily disabilitating diseases are caused by recessive founder mutations. They include, among others, neuromuscular diseases such as congenital muscular dystrophy and spastic paraglegia and also severe genodermatoses such as dystrophic epidermolysis bullosa and xeroderma pigmentosa. Conclusion This report provides informations on founder mutations for 73 genetic diseases either specific to Tunisians or shared by other populations. Taking into account the relatively high number and frequency of genetic diseases in the region and the limited resources, screening for these founder mutations should provide a rapid and cost effective tool for

    Full Text Available Abstract Background This paper studies the determinants of utilization of health care services, especially for treatment of febrile illness in the malaria endemic area of north-east India. Methods An area served by two districts of Upper Assam representing people living in malaria endemic area was selected for household survey. A sample of 1,989 households, in which at least one member of household suffered from febrile illness during last three months and received treatment from health service providers, were selected randomly and interviewed by using the structured questionnaire. The individual characteristics of patients including social indicators, area of residence and distance of health service centers has been used to discriminate or group the patients with respect to their initial and final choice of service providers. Results Of 1,989 surveyed households, initial choice of treatment-seeking for febrile illness was self-medication (17.8%, traditional healer (Vaidya(39.2%, government (29.3% and private (13.7% health services. Multinomial logistic regression (MLR analysis exhibits the influence of occupation, area of residence and ethnicity on choice of health service providers. The traditional system of medicine was commonly used by the people living in remote areas compared with towns. As all the febrile cases finally received treatment either from government or private health service providers, the odds (Multivariate Rate Ratio was almost three-times higher in favour of government services for lower households income people compared to private. Conclusion The study indicates the popular use of self-medication and traditional system especially in remote areas, which may be the main cause of delay in diagnosis of malaria.

    The Middle-East, mostly at its southern edge together with North Africa, the northern edge of the Sahara Desert, are located at the boundary between high- to-mid latitude and tropical-subtropical climate systems. The geographical duality of desert adjacent to Mediterranean-type climate regions played and still plays a major role on the water availability. Thanks to the number of important paleoclimate studies that been made on accurate dating of cave speleothems in Southern Arabia and Oman (Fleitmann et al., 2011) and in the northeast Sahara, the Negev Desert Israel (Vaks et al., 2010) and the study of sapropels in Eastern and central Mediterranean (Almogi-Labin et al., 2009; Osborne et al, 2008), it is clear that the region was graced with water during peak interglacials when the African monsoon and westerly storm/rainfall systems intensified. Northward penetration of the Inter Tropical Convergence Zone over the Arabian and African continents resulted in increased discharge of the Nile River and rivers that emerged from central Sahara into the Eastern Mediterranean Sea. Correspondingly, enhanced westerly wind activity led to an increase in rainfall from Atlantic-Mediterranean sources over the entire Mediterranean basin, which even penetrated south into the north-east corner of the Sahara Desert. The Saharo-Arabian Desert became narrower and climatic "windows" opened for the dispersal of hominids and animals out of the African continent at 250-239, 210-193, 138-120, 108-98, 87-84 and 10-6.5 ka BP, with severe dry conditions in between. Greening of the Sahara Desert at these intervals is supported also by various marine and terrestrial records, such as corals, lakes, tufa deposits and archeological findings. Dry conditions prevailed in the Sahara desert during glacials. This is in contrast to the climatic conditions in the Eastern Mediterranean coastal region and the Jordan Rift Valley (Bar-Matthews et al., 2003; Lisker et al., 2010), where water was available for

    Obtaining reliable estimates for the timing of eclogite-facies metamorphism is critical to establishing models for the formation and exhumation of high-pressure and ultrahigh-pressure (UHP) metamorphic terranes in collisional orogens. The presence of pressure-dependent phases, such as coesite, included in metamorphic zircon is generally regarded as evidence that zircon growth occurred at UHP conditions and, ifdated, should provide the necessary timing information. We report U-Pb sensitive high-resolution ion microprobe (SHRIMP) ages and trace-element SHRIMP data from coesite-bearing zircon suites formed during UHP metamorphism in the North- East Greenland Caledonides. Kyanite eclogite and quartzofeldspathic host gneiss samples from an island in J??kelbugt (78??00'N, 18??04'W) contained subspherical zircons with well-defined domains in cathodoluminescence (CL) images. The presence of coesite is confirmed by Raman spectroscopy in six zircons from four samples. Additional components of the eclogite-facies inclusion suite include kyanite, omphacite, garnet, and rutile. The trace-element signatures in core domains reflect modification of igneous protolith zircon. Rim signatures show flat heavy rare earth element (HREE) patterns that are characteristic of eclogite-facies zircon. The kyanite eclogites generally lack a Eu anomaly, whereas a negative Eu anomaly persists in all domains of the host gneiss. The 207Pb- corrected 206Pb/238U ages range from 330 to 390 Ma for the host gneiss and 330-370 Ma for the kyanite eclogite. Weighted mean 206Pb/238U ages for coesite-bearing domains vary from 364 ?? 8 Ma for the host gneiss to 350 ?? 4 Ma for kyanite eclogite. The combined U-Pb and REE data interpreted in conjunction with observed CL domains and inclusion suites suggest that (1) Caledonian metamorphic zircon formed by both new zircon growth and recrystallization, (2) UHP metamorphism occurred near the end of the Caledonian collision, and (3) the 30-50m.y. span of ages

    Rodents affect the post-dispersal fate of seeds by acting either as on-site seed predators or as secondary dispersers when they scatter-hoard seeds. The tropical forests of north-east India harbour a high diversity of little-studied terrestrial murid and hystricid rodents. We examined the role played by these rodents in determining the seed fates of tropical evergreen tree species in a forest site in north-east India. We selected ten tree species (3 mammal-dispersed and 7 bird-dispersed) that varied in seed size and followed the fates of 10,777 tagged seeds. We used camera traps to determine the identity of rodent visitors, visitation rates and their seed-handling behavior. Seeds of all tree species were handled by at least one rodent taxon. Overall rates of seed removal (44.5%) were much higher than direct on-site seed predation (9.9%), but seed-handling behavior differed between the terrestrial rodent groups: two species of murid rodents removed and cached seeds, and two species of porcupines were on-site seed predators. In addition, a true cricket, Brachytrupes sp., cached seeds of three species underground. We found 309 caches formed by the rodents and the cricket; most were single-seeded (79%) and seeds were moved up to 19 m. Over 40% of seeds were re-cached from primary cache locations, while about 12% germinated in the primary caches. Seed removal rates varied widely amongst tree species, from 3% in Beilschmiedia assamica to 97% in Actinodaphne obovata. Seed predation was observed in nine species. Chisocheton cumingianus (57%) and Prunus ceylanica (25%) had moderate levels of seed predation while the remaining species had less than 10% seed predation. We hypothesized that seed traits that provide information on resource quantity would influence rodent choice of a seed, while traits that determine resource accessibility would influence whether seeds are removed or eaten. Removal rates significantly decreased (p seed size. Removal rates were significantly

    The sea urchin roe reach a very high price in the international fish product market favoring the increase in the catches of this resource and overfishing in some countries. In the Island of Margarita (Venezuela) some species, Lytechinus variegatus (Lamarck) among others, are consumed as food but studies to determine abundance of the resource are unknown. Nine sample stations (depth less than 2 m) on the North, East and West coast of Margarita Island were visited in six different occasions between February/1998 and February/1999 to study the population density (urchins/m2) of L. variegatus. Using a quadrat (0.25 m2) thrown 8 times over seagrasses (Thalassia testudinum) beds and over submerged rocks and the urchins removed by dive. The diameter of each specimen was measured and returned to the sea. The water temperature, salinity and dissolved oxygen of each site was measured. Were collected a total of 2,073 urchins with a diameter ranging from 11.0 to 84.5 mm and population density between 1 to 52 urchins/m2. The mean size of specimens collected in the stations was between 30.44 and 55.09 mm and average density fluctuated between 3.2 to 43.2 urchins/m2. The station where sea urchins were found to be most abundant was the North coast (Manzanillo fishing villae) where they live on rocks with a density (38 a 52/m2) far over the values previously cited for the Caribbean sea and Florida.

    The study of subsistence strategies among Neolithic communities in north-east Iberia, late-fifth to early-fourth millennia cal BC, enables a more in-depth study of the activities and behavior of the inhabitants of this region, where paleodiets have been little studied. The objectives of this study are, therefore, to determine the diet and subsistence patterns of those communities and to consider whether any relation existed between their subsistence strategies and environmental, geographic, and/or social factors. Bone samples from 25 middle Neolithic human individuals at seven archeological sites and comparative faunal samples were analyzed, and compared with contemporary series in Mediterranean Europe. Carbon and nitrogen isotope ratios (δ 13 C and δ 15 N) of bone collagen were studied to determine the dietary patterns. Dietary habits proved to be similar between communities, apart from some interpopulational variations in subsistence strategies. Their diet was based on C 3 terrestrial resources with a major vegetal protein component. The reported variations in interpopulational subsistence strategies among the compared Mediterranean societies do not seem to be directly related to the settlement region. Together with archeological data, this indicates the influence of socioeconomic factors in the Neolithic human diet. A general tendency toward a lesser use of aquatic resources is seen in this period in Iberia and the rest of the Mediterranean, as also documented for contemporary communities in the west and north of Europe. The data obtained will be important for further studies of socioeconomic patterns in European Neolithic societies. © 2016 Wiley Periodicals, Inc.

    Atmospheric new particle formation (NPF) and growth significantly influences the indirect aerosol-cloud effect within the polar climate system. In this work, the aerosol population is categorised via cluster analysis of aerosol number size distributions (9-915 nm, 65 bins) taken at Villum Research Station, Station Nord (VRS) in North Greenland during a 7 year record (2010-2016). Data are clustered at daily averaged resolution; in total, we classified six categories, five of which clearly describe the ultrafine aerosol population, one of which is linked to nucleation events (up to 39% during summer). Air mass trajectory analyses tie these frequent nucleation events to biogenic precursors released by open water and melting sea ice regions. NPF events in the studied regions seem not to be related to bird colonies from coastal zones. Our results show a negative correlation (r = -0.89) between NPF events and sea ice extent, suggesting the impact of ultrafine Arctic aerosols is likely to increase in the future, given the likely increased sea ice melting. Understanding the composition and the sources of Arctic aerosols requires further integrated studies with joint multi-component ocean-atmosphere observation and modelling.

    Full Text Available Indigenous strains of Trichoderma species isolated from rhizosphere soils of Tea gardens of Assam, north eastern state of India were assessed for in vitro antagonism against two important tea fungal pathogens namely Pestalotia theae and Fusarium solani. A potent antagonist against both tea pathogenic fungi, designated as SDRLIN1, was selected and identified as Trichoderma viride. The strain also showed substantial antifungal activity against five standard phytopathogenic fungi. Culture filtrate collected from stationary growth phase of the antagonist demonstrated a significantly higher degree of inhibitory activity against all the test fungi, demonstrating the presence of an optimal blend of extracellular antifungal metabolites. Moreover, quantitative enzyme assay of exponential and stationary culture filtrates revealed that the activity of cellulase, β-1,3-glucanase, pectinase, and amylase was highest in the exponential phase, whereas the activity of proteases and chitinase was noted highest in the stationary phase. Morphological changes such as hyphal swelling and distortion were also observed in the fungal pathogen grown on potato dextrose agar containing stationary phase culture filtrate. Moreover, the antifungal activity of the filtrate was significantly reduced but not entirely after heat or proteinase K treatment, demonstrating substantial role of certain unknown thermostable antifungal compound(s in the inhibitory activity.

    An exceptional number of Middle Eastern and North African nations have recently expressed interest in developing nuclear energy for peaceful purposes. Many of these countries have explored nuclear research in limited ways in the past, but the current focused interest and application of resources towards developing nuclear-generated electricity and nuclear-powered desalination plants is unprecedented. Consequently, questions arise in response to this emerging trend: What instigated this interest? To what end(s) will a nuclear program be applied? Does the country have adequate technical, political, legislative, nonproliferation, and safety infrastructure required for the capability desired? If so, what are the next steps for a country in preparation for a future nuclear program? And if not, what collaboration efforts are possible with the United States or others? This report provides information on the capabilities and interests of 13 countries in the region in nuclear energy programs in light of safety, nonproliferation and security concerns. It also provides information useful for determining potential for offering technical collaboration, financial aid, and/or political support.

    A critical analysis is provided of the recent reorganisations of the downstream and petrochemical activities of BP and Shell. BP (or BP Amoco including Arco) and Shell are preparing for the next decade anticipating the environment and changing the companies to maximise their profitability in that environment. For the oil producing countries of the Middle East and North Africa (MENA), there are lessons to be learned both from the forecasts which BP Amoco and Shell are making and from the way these companies intend to operate. BP Amoco's view of oil refining is that the surplus capacity is endemic; Shell's view is that it is transient. BP Amoco will market oil products selectively across the world; Shell is still intent on a global approach. Both BP Amoco and Shell will minimise their wholesaling activities in the retail market and expand their merchandising with ever better quality sites. In the petrochemicals sector, the companies are taking similar actions, ie concentrating on positions of strength and selling business activities with low market shares or poor profitability. Petrochemical sites will be favoured when they have access to company produced hydrocarbon feedstocks. From the analysis, it is suggested that MENA oil companies will need to consider carefully the timing of any new refinery building. The reorganisation of the major OECD-based oil companies should offer opportunities for MENA companies to secure outlets for LPG and condensates, to form marketing alliances in OECD markets and to become involved in OECD-based petrochemical businesses.

    A majority of the countries in the Middle East and North Africa (MENA) region suffer from water scarcity due in part to widespread rainfall deficits, unprecedented levels of water demand, and the inefficient use of renewable freshwater resources. Since a majority of the water withdrawal in the MENA is used for irrigation, there is a desperate need for improved understanding of irrigation practices and agricultural water use in the region. Here, satellite-derived irrigation maps and crop-type agricultural data are applied to the Land Data Assimilation System for the MENA region (MENA LDAS), designed to provide regional, gridded fields of hydrological states and fluxes relevant for water resources assessments. Within MENA-LDAS, the Catchment Land Surface Model (CLSM) simulates the location, timing, and amount of water applied through agricultural irrigation practices over the region from 2002-2012. In addition to simulating the irrigation impact on evapotranspiration, soil moisture, and runoff, we also investigate regional changes in terrestrial water storage (TWS) observed from the Gravity Recovery and Climate Experiment (GRACE) and simulated by CLSM.

  18. Review of the continued suitability of the dumping site for radioactive waste in the North-East Atlantic

    1980-04-01

    Under the terms of the Decision of the OECD Council establishing a Multilateral Consultation and Surveillance Mechanism for Sea Dumping of Radioactive Waste, NEA is requested to assess, in consultation with the Environment Committee, the suitability of dumping sites proposed by the national authorities of Participating countries and to keep under review those previously considered suitable. Since 1974 radioactive waste sea dumping operations have been carried out in a single site located in the North-East Atlantic region. To fulfil the objectives of the Council Decision, an international group of oceanographic and radiation protection experts was convened by NEA in November 1979 to undertake a review of the continued suitability of the dumping site, taking into account the relevant provisions of the London Dumping Convention and the IAEA Definition and Recommendations for the purposes of the Convention. The results of the review are contained in this Report. The Steering Committee for Nuclear Energy confirmed in April 1980 that, on the basis of the review, the existing site was suitable for continued dumping of radioactive waste for the next five years, under the conditions specified by the Group of Experts in their conclusions and recommendations. At the same time, the Steering Committee for Nuclear Energy agreed on the need for developing a co-ordinated site-specific scientific programme to increase current knowledge of the processes controlling the transfert of radionuclides in the marine environment, so that future assessments can be based on more accurate and comprehensive scientific data

    Mapping land use/land cover (LULC) changes at regional scales is essential for a wide range of applications, including landslide, erosion, land planning, global warming etc. LULC alterations (based especially on human activities), negatively effect the patterns of climate, the patterns of natural hazard and socio-economic dynamics in global and local scale. In this study, LULC changes are investigated by using of Remote Sensing and Geographic Information Systems (GIS) in Rize, North-East Turkey. For this purpose, firstly supervised classification technique is applied to Landsat images acquired in 1976 and 2000. Image Classification of six reflective bands of two Landsat images is carried out by using maximum likelihood method with the aid of ground truth data obtained from aerial images dated 1973 and 2002. The second part focused on land use land cover changes by using change detection comparison (pixel by pixel). In third part of the study, the land cover changes are analyzed according to the topographic structure (slope and altitude) by using GIS functions. The results indicate that severe land cover changes have occurred in agricultural (36.2%) (especially in tea gardens), urban (117%), pasture (-72.8%) and forestry (-12.8%) areas has been experienced in the region between 1976 and 2000. It was seen that the LULC changes were mostly occurred in coastal areas and in areas having low slope values.
