    Full Text Available Accurately mapping and monitoring glacier changes over decades is important for providing information to support sustainable use of water resource in arid regions of northwest China. Since 1970, glaciers in the Eastern Altun Mountains showed remarkable recession. Further study is indispensable to indicate the extent and amplitude of glacial change at basin and individual glacier scale. In this study, spatiotemporal glacier changes referring to the year 1972, 1990, 2000 and 2010 were studied for the Eastern Altun Mountains using Landsat MSS/TM/ETM+ images and glacier volume-area scaling. The results demonstrated that the total area and volume of glaciers in EAMs decreased significantly by 10.70±0.57 km² (19.56±10.41% and 0.61±0.03 km³ (23.19±11.40% during 1972-2010, respectively. More than half of the total receding area occurred during 1990-2000, primarily due to higher temperature increasing. However, varied response of individual glaciers indicated that glacier change was also affected by glacier dynamics, which was related to local topography. In addition, five glaciers unrecorded in the glacier inventory of China were reported in this study.

    The Bashikaogong-Shimierbulake granitoid complex is about 30 km long and 2-6 km wide,with an area of 140 km2,located at the north margin of the Bashikaogong Basin in the north Altun terrain.It intruded into schist,metapelite and metatuff of Precambrian ages.This granitoid complex consists of darkish quartz diorite,grey granite,pink granite and pegmatite.Geochemically,the quartz diorite has I-type granite affinity and belongs to Calc-alkaline sereies,and the other granites have S-type affinity and to high-K calc-alkaline series.Zircon SHRIMP U-Pb dating shows that the quartz diorite has a bigger age than those of other granites,which is 481.6±5.6 Ma for quartz diorite,437.0±3.0 Ma-433.1±3.4 Ma for grey granite and 443±11 Ma-434.6±1.6 Ma for pink granite,respectively.Combined with regional geology,we think that the quartz diorite formed in tectonic environment related to oceanic crust subduction and the granites in post-collision.

    Abundant early Paleozoic granitoid plutons are widely distributed in the North Altun orogenic belt. These rocks provide clues to the tectonic evolution of the North Altun orogenic belt and adjacent areas. In this paper, we report an integrated study of petrological features, U-Pb zircon dating, in situ zircon Hf isotope and whole-rock geochemical compositions for the Abei, 4337 Highland and Kaladawan Plutons from north to south in the North Altun orogenic belt. The dating yielded magma crystallization ages of 514 Ma for the Abei Pluton, 494 Ma for the 4337 Highland Pluton and 480-460 Ma for the Kaladawan Pluton, suggesting that they are all products of oceanic slab subduction because of the age constraint. The Abei monzogranites derived from the recycle of Paleoproterozoic continental crust under low-pressure and high-temperature conditions are products of subduction initiation. The 4337 Highland granodiorites have some adakitic geochemical signatures and are sourced from partial melting of thickened mafic lower continental crust. The Kaladawan quartz diorites are produced by partial melting of mantle wedge according to the positive εHf(t) values, and the Kaladawan monzogranite-syenogranite are derived from partial melting of Neoproterozoic continental crust mixing the juvenile underplated mafic material from the depleted mantle. These results, together with existing data, provide significant information about the evolution history of oceanic crust subduction during the 520-460 Ma. The initiation of subduction occurred during 520-500 Ma with formation of Abei Pluton; subsequent transition from steep-angle to flat-slab subduction at ca.500 Ma due to the arrival of buoyant oceanic plateaus, which induces the formation of 4337 Highland Pluton. With ongoing subduction, the steep-angle subduction system is reestablished to cause the formation of 480-460 Ma Kaladawan Pluton. Meanwhile, it is this model that account for the temporal-spatial distribution of these early

    The Altun (or Altyn Tagh) fault displays a geometry of overlapping of linear and arcuate segments and shows strong inhomogeneity in time and space. It is a gigantic fault system with complex mechanical behaviours including thrusting, sinistral strike slip and normal slip. The strike slip and normal slip mainly occurred in the Cretaceous–Cenozoic and Plio–Quaternary respectively, whereas the thrusting was a deformation event that has played a dominant role since the late Palaeozoic (for a duration of about 305 Ma). The formation of the Altun fault was related to strong inhomogeneous deformation of the massifs on its two sides (in the hinterland of the Altun Mountains contractional deformation predominated and in the Qilian massif thrust propagation was dominant). The fault experienced a dynamic process of successive break-up and connection of its segments and gradual propagation, which was synchronous with the development of an overstep thrust sequence in the Qilian massif and the uplift of the Qinghai-Tibet plateau. With southward propagation of the thrust sequence and continued uplift of the plateau, the NE tip of the Altun fault moved in a NE direction, while the SW tip grew in a SW direction.

    Full Text Available Even though over the years has enjoyed wide media coverage, with highlighted aspects, discrepancies and inequalities of economic potential between different regions of the world, or even parts of the same countries always remained topical. Difficulties arising from these differences were always felt, extremely painful by humans. Analyzing distinctly, participation of each county to the GDP of the Northwest Region and the composition of all indicators, we can identify significant discrepancies between counties, regions and municipalities. This is one of the reasons that led us trying to identify the causes that generated the current situation. From the perspective of the contribution of each county in the Northwest Region to Region's domestic product composition, the first place is taken by Cluj county 32.3%, followed by Bihor with 24.3%, Maramures, with 14.9% Satu-Mare, 12.1%, Bistrita-Nasaud, 9.1% and 7.2% Salaj. Consulting of the Regional Operational Programme 2007-2013 indicates that the poorest areas in the Northwest Region are in Maramures and Bistrita-Nasaud. An important part of the active population of North-West Region was employed in public enterprises and an increase of unemployment in the counties of Salaj, Satu Mare and Maramures became predictable, imminent amid restructuring of public enterprises with losses. Studies of employed population by sectors of the economy, shows a high rate of population employed in services in the counties of Cluj and Bihor and high employment in agriculture on other four counties. In a modern market economy, services are most concentrated labors, and how the workforce is distributed in the Northwest region also shows an imbalance. How Northwest Region is participating in international economic cycle has major effects on the population's living standards. Relevant for the inter-district disparities analysis is the human and agents behavior analysis and the savings and loan relationships. How people

    Tectonic movements formed several unconformities in the north-west margin of the Junggar basin. Based on data of outcrop, core, and samples, the unconformity is a structural body whose formation associates with weathering, leaching, and onlap. At the same time, the structural body may be divided into three layers, including upper layer, mid layer, and lower layer. The upper layer with good primary porosity serves as the hydrocarbon migration system, and also accumulates the hydrocarbon. The mid layer with compactness and ductility can play a role as cap rock, the strength of which increases with depth. The lower layer with good secondary porosity due to weathering and leaching can form the stratigraphic truncation traps. A typical stratigraphic reservoir lying in the unconformity between the Jurassic and Triassic in the north-west margin of the Junggar basin was meticulously analyzed in order to reveal the key controlling factors. The results showed that the hydrocarbon distribution in the stratigraphic onlap reservoirs was controlled by the onlap line, the hydrocarbon distribution in the stratigraphic truncation reservoirs was confined by the truncation line, and the mid layer acted as the key sealing rock. So a conclusion was drawn that "two lines (onlap line and truncation line) and a body (unconformity structural body)" control the formation and distribution of stratigraphic reservoirs.

    Massive coral skeletal growth parameters (skeletal density, extension and calcification rate) are one of the indexes of coral health and ecological response to the ambient environmental changes such as ocean acidification (OA) and global warming. To predict and evaluate the influence of the environment changes to the coral skeletal growth, the coral skeletal growth model (CGM) is one of the useful tools. The CGM is one of the equations consisted of the coral skeletal parameters as response variables and physical or chemical environmental factor such as sea surface temperature (SST), pH, insolation and so on as explanatory variables. The constructing of CGM is equal to the forming the equation and deciding its coefficients. However, there are no universal coral growth models. The aim of our study is to construct the GCM. It is important to analyze coral growth parameters in the past natural condition by using core of massive coral skeleton for our study. In the natural condition, high-latitude area is the best place to evaluate the influence of OA to coral skeletal growth because OA influence ocean organisms from high-latitude area where predicted to affected due to low SST and low carbonate saturation levels induced by dissolved atmospheric CO2 to the sea compared to tropical-subtropical area.This study shows recent temperate coral growth parameters collected from Kagoshima (c.a. 60years), Kochi (c.a. 25 years) and Wakayama (c.a. 30 years) in North-west Pacific, Japan and discusses the universal coral growth model. We quantified the coral growth parameters with uncertainty for the first time. The chronology was developed by δ 18O variant of coral skeletons making sure the forming time of high-low skeletal density area. To evaluate influence of annual SST, precipitation and insolation to coral calcification rate in the natural condition, we performed the regression tree and multiple regression models analysis. As the results, there were non-significances between

    The initial contact of European populations with indigenous populations of the Americas produced diverse admixture processes across North, Central, and South America. Recent studies have examined the genetic structure of indigenous populations of Latin America and the Caribbean and their admixed descendants, reporting on the genomic impact of the history of admixture with colonizing populations of European and African ancestry. However, relatively little genomic research has been conducted on admixture in indigenous North American populations. In this study, we analyze genomic data at 475,109 single-nucleotide polymorphisms sampled in indigenous peoples of the Pacific Northwest in British Columbia and Southeast Alaska, populations with a well-documented history of contact with European and Asian traders, fishermen, and contract laborers. We find that the indigenous populations of the Pacific Northwest have higher gene diversity than Latin American indigenous populations. Among the Pacific Northwest populations, interior groups provide more evidence for East Asian admixture, whereas coastal groups have higher levels of European admixture. In contrast with many Latin American indigenous populations, the variance of admixture is high in each of the Pacific Northwest indigenous populations, as expected for recent and ongoing admixture processes. The results reveal some similarities but notable differences between admixture patterns in the Pacific Northwest and those in Latin America, contributing to a more detailed understanding of the genomic consequences of European colonization events throughout the Americas.

    To evaluate the influence of some risk factors on the incidence rate of Lyme disease and the main clinical manifestations. A retrospective study of Lyme disease (2006-2013) was performed in north-west Spain; we included only patients who fulfilled the epidemiological surveillance criteria defined by the Centers for Disease Control and Prevention. The incidence rate varied between 2.64 and 11.61/100,000 inhabitants/year. Significant differences were found in relation to habitat, age and area of residence. Patients showed neurological (67.59%), dermatological (47.22%), rheumatological (15.74%) and cardiac (13.88%) manifestations, alone or combined. Due to the increase of the disease in north-west Spain and the differences observed between the different areas, epidemiological studies are needed that increase the index of diagnostic suspicion and lead to the implementation of effective prevention measures.

    The subsidence of the Earth surface is a phenomenon that occurs in some places in the world which overuse underground sources of water. As Iran has semi-arid and arid climate and the rate of rainfall is lower than the mean rate in the world then nowadays we are encountered by over-exploitation of groundwater in agricultural areas and also for extending the cities and industrial areas. Geodetic measurements i.e., repeated leveling measurements of first order leveling network of Iran and continuous GPS measurements of Iranian Permanent GPS Network of Iran (IPGN), showed that there are subsidence areas in the north-west of Iran. In this paper we try to find the area and rate of subsidence in the north-west of Iran using InSAR and geodetic techniques. The result of InSAR technique shows a better understanding on this phenomenon in these areas and has a good consistency with accurate geodetic measurements.

    Full Text Available Background and Objectives : Familial Mediterranean Fever, an autosomal recessive disorder, is the most common and well known periodical fevers syndrome. Disease is mainly prevalent among non-Ashkenazi Jews, Arabs, Turks and Armenia. According to the geographical location of North-West of Iran, neighboring with two high risk FMF population (Turkey and Armenia, the prevalence of FMF in this region of Iran is not unlikely. The aim of this study was to estimate the carriers rate of FMF common mutations in healthy control people. Results can be potentially useful to estimate prevalence of disease.   Methods : Randomly 200 samples from healthy people [non-FMF] from North-West of Iran selected. After taking consent, DNA was extracted from blood samples of these groups. Then mutations were evaluated using ARMS-PCR and RFLP-PCR techniques.   Results : from 400 studied alleles, 44 and 7 mutant alleles were found for E148Q and V726A respectively. For 2 other mutations, no mutant alleles were found. The total allelic frequency for these four common mutations was 0.132. The carriers rate was 23.4%.   Conclusion : This study showed that E148Q has high mutation frequency relative to other mutations in North-West of Iran.

    2014-06-01

    Full Text Available The question of how we can define salience, what properties it includes and how we can quantify it have been discussed widely over the past thirty years but we still have more questions than answers about this phenomenon, e. g. not only how salience arises, but also how we can define it. However, despite the lack of a clear definition, salience is often taken into account as an explanatory factor in language change. The scientific discourse on salience has in most cases revolved around phonetic features, while hardly any variables on other linguistic levels have been investigated in terms of their salience. Hence, one goal of this paper is to argue for an expanded view of salience in the sociolinguistic context. This article investigates the variation and change of two groups of variables in Carlisle, an urban speech community in the north west of England. I analyse the variable (th and in particular the replacement of /θ/ with [f] which is widely known as th-fronting. The use of three discourse markers is also examined. Both groups of features will then be discussed in the light of sociolinguistic salience.

    An investigation was conducted from summer 2012 to winter 2013 at 25 stations along the Tunisian coast near Kef Abbed at Marsa Dhouiba (north-east Mediterranean Sea) to analyse grain size, sediment mineralogy and currents. Particle-size analysis shows that sand deposits at shallow depths are characterised by S-shaped curves, indicating a degree of agitation and possible transport by rip currents near the bottom. At greater depths (between 10 and 30 m), the bottom is covered by coarse sand and gravel. A current was observed transporting sediment eastward along the coast; another seaward current was also noted. Generated by wind, swell and especially waves from west to north-west, the two currents transport clay and silt-sized sediment seaward. An Acoustic Doppler Current Profiler showed Marsa Dhouiba's coastal current to follow a direction 175° East, with its main axis running north/north-west parallel to the coast and its minor axis also running north/north-west. Analysis of current components indicates that the velocities u and v are oriented north to south. Sediment evolution in shallow waters is dependent on detrital inputs from streams and winds. The coarse fraction of surface sediments in Marsa Dhouiba presents 87% of total sediments and is located at depths of 10-30 m. Sediment dynamics in the Marsa Dhouiba region are closely related to the west/north-west swell.

    The process of reduction of agrolandscapes has taken place some decades in the North-Western European Russia. During 100 last years the area of agricultural lands have reduced in 1,4 times on the Karelian Isthmus. The most part of it had been abandoned after change of State border after of the Second World War. The processes of overgrowing of the former agricultural lands are studied on the landscapes base. The types of landscapes are distinguished on the based of the morphological relief symptoms, characteristics of the structure rock and the humid regime. Agricultural lands occupy landscapes such as kames, sandy, sandy-loam, clayey plains, sometimes with excess moistening, sandy fluvioglacial plains, loamy morainic plains, mesotrophic and evtrophic peat-bogs. Four stages can be revealed. I - (period to 20 years after termination of agricultural use) - grass-herb meadow with unclosed brush II - (20 - 40) - shrub layer with closed or low-closed canopy and unclosed or low closed small-leaved regrowth III - (40 - 80) - closed small-leaved forest, sometime including the coniferous trees IY - predomination of the coniferous on small-leaved trees Reestablish vegetation successions can be realised by different ways, with different rate, including various trees and ecological groups of species in different landscapes. In the different sites many traits in common are discovered during this processes. The processes taking place in soil of abandoned agricultural lands are expressed more poorly than in vegetation as soil is more "conservative" element of landscape. Now most area occupies former agricultural lands, inhering on III stage and presenting itself small-leaved forest. Over the last decade because of a change in the socio-political situation there has emerged a tendency towards an increase in the area of the cultivated land in the Karelian Isthmus including the secondary development of previously abandoned lands. However, this process is going on spontaneously; there

    The upwelling area off North-West Africa is characterized by high export production, high nitrate and low oxygen concentration in bottom waters. The underlying sediment consists of sands that cover most of the continental shelf. Due to their permeability sands allow for fast advective pore water transport and can exhibit high rates of nitrogen (N) loss via denitrification as reported for anthropogenically eutrophied regions. However, N loss from sands underlying naturally eutrophied waters is not well studied, and in particular, N loss from the North-West African shelf is poorly constrained. During two research cruises in April/May 2010/2011, sediment was sampled along the North-West African shelf and volumetric denitrification rates were measured in sediment layers down to 8 cm depth using slurry incubations with 15N-labeled nitrate. Areal N loss was calculated by integrating volumetric rates down to the nitrate penetration depth derived from pore water profiles. Areal N loss was neither correlated with water depth nor with bottom water concentrations of nitrate and oxygen but was strongly dependent on sediment grain size and permeability. The derived empirical relation between benthic N loss and grains size suggests that pore water advection is an important regulating parameter for benthic denitrification in sands and further allowed extrapolating rates to an area of 53,000 km2 using detailed sediment maps. Denitrification from this region amounts to 995 kt yr-1 (average 3.6 mmol m-2 d-1) which is 4 times higher than previous estimates based on diffusive pore water transport. Sandy sediments cover 50-60% of the continental shelf and thus may contribute significantly to the global benthic N loss.

    Full Text Available Soil is a vital factor for human activities and also for all ecosystems development. Soil is in a continue evolution influencedby pedogenetic factors and human activities. Following the last decades intense industrialization, soil pollution intensified. In 6North-West Region, areas with different soil pollution levels have been identified. According to the partial inventory, thisphenomenon was generated especially by the industrial activities, most of all by mining and chemical industry. Among these, a goodexample is the hexachlorocyclohexane soil pollution from Turda Area. The soil quality from this region is also affected by otheractivities like: waste disposal, oil and natural gases extraction.

    Aim to linking the variability of drought in northwest China to the oceanic influence of North Atlantic SSTs at the background of global warming and at the regional climate change shifting stages, year aridity index variations in northwest China and summer North Atlantic sea surface temperature (SST) variations are examined for the 44 a period of 1961--2004 using singular value de-composition (SVD) analysis. Results show that the SST anomalies (SSTA) in the North Atlantic in summer reflected three basic models. The first SVD mode of SST pattern shows a dipole - like variation with the positive center located at southwest and nega-tive center at northeast of extratropical North Atlantic. And it strongly relates to the positive trend in AI variation in northwest China. The second coupled modes display the coherent positive anomalies in extratropical North Atlantic SST and the marked opposite trend of AI variability between north and south of Xinjiang. In addition, the lag correlation analysis of the first mode of SSTA and geopotential heights at 500 hPa variations also shows that the indication of the former influencing the latter configuration, which re-sult in higher air temperature and less precipitation when the SSTA in the North Atlantic Ocean in summer motivated Eurasian cir-culation of EA pattern, further to influence the wet - dry variations in northwest China by the ocean-to - atmosphere forcing.

    Full Text Available Physical chemical properties of oil emulsions of two different oilfields of Kazakhstan - NorthWest Konys and Zhanaozen by their densities related to light and heavy oils, respectively, were studied. Qualitative and quantitative compositions of main stabilizing components of oil emulsions (resins, asphaltenes and high molecular paraffins were determined. The dispersion degree of oil emulsions was determined using optical microscopy. It was found that samples relate to fine dispersed oil emulsions by dispersion, and to poorly stable (Konys and highly stable (Zhanaozen oil emulsions by ability to form emulsions. Light oil of Konys oilfield (ρ = 833 kg/m3 at 20°C contains 11.5% of paraffins, 0.69% resins, 0.19% asphaltenes. The same measurements were carried out for heavy oil of Zhanaozen (943 kg/m3 at 20°C where paraffin content exceeded 30%, amount of resins was 1.5% and asphaltenes – 0.6%. The sample of Zhanaozen oilfield contains 33% of water, 154.8 mg/L chlorides, 5.22 % mechanical impurities, and for oilfield samples of North-West Konys the water content was 7.5%, the content of chloride salts – 18 mg/L, and 0.002% of mechanical impurities.

  20. Evaluating Adaptive Governance Approaches to Sustainable Water Management in North-West Thailand

    2013-04-01

    Adaptive governance is advanced as a potent means of addressing institutional fit of natural resource systems with prevailing modes of political-administrative management. Its advocates also argue that it enhances participatory and learning opportunities for stakeholders over time. Yet an increasing number of studies demonstrate real difficulties in implementing adaptive governance `solutions'. This paper builds on these debates by examining the introduction of adaptive governance to water management in Chiang Mai province, north-west Thailand. The paper considers, first, the limitations of current water governance modes at the provincial scale, and the rationale for implementation of an adaptive approach. The new approach is then critically examined, with its initial performance and likely future success evaluated by (i) analysis of water stakeholders' opinions of its first year of operation; and (ii) comparison of its governance attributes against recent empirical accounts of implementation difficulty and failure of adaptive governance of natural resource management more generally. The analysis confirms the potentially significant role that the new approach can play in brokering and resolving the underlying differences in stakeholder representation and knowledge construction at the heart of the prevailing water governance modes in north-west Thailand.

    Relapsing fever is caused by the Borrelia species of spirochetes. Louse-borne epidemics of the disease may happen but the endemic disease is generally transmitted to humans by the bite of an infected tick (Ornithodorus). Clinical and laboratory findings of tick-borne relapsing fever in children in the north-west of Iran, Qazvin, were evaluated. This study was conducted from September 1992 to September 2012. Records from 53 cases of tick-borne relapsing fever (TBRF) were reviewed. In positive cases, febrile illness, and spirochetes were recognized in peripheral blood preparations. Of the 53 children younger than 12 years, fifty two percent were male and about one third (34%) of the patients were in the age range of 7-12 years. The disease is recorded through the whole year but its peak occurs during summer (52.8%) and autumn (32.1%). Sixty eight percent of patients were living in urban areas but had frequent travel to rural area. Thirty two percent of the cases were living in rural areas where their dwellings were close to animal shelters. All (100%) of the 53 subjects were febrile. Travellers to the rural areas with high prevalence of the disease should be attentive of the risk of tick-borne relapsing fever and use suitable control measures. Consequently relapsing fever should be considered when patients who live in or have vacationed in north-west of Iran show a recurring febrile illness.

  2. Fluorine emission from com-bustion of steam coal of North China Plate and Northwest China

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    To study the amount of fluorine emission from the combustion of the steam coal (mainly Permo-Carbonif- erous coal) from the North China Plate and Northwest China, the fluorine contents of the coal, the fly ash and the cinder in high-temperature power stations as well as mid-low temperature power stations have been analyzed. This note provides a rough estimate of the total annual amount of fluorine emission as well as emission ratio from steam coal combustion in China. Our results show that by combustion of 1 t of Permo-Carboniferous coal (containing roughly 100 g fluorine), high-temperature power stations emit roughly 90 g fluorine into the atmosphere. The fluorine emission ratio of coal combustion in high-temperature power stations is about 96% and that in mid-low temperature power stations is about 78%. A total of 800 million tons of coal is burnt in China every year, and the coal comes mainly from Permo- Carboniferous deposite in the North China Plate and Northwest China coal mines. Taking the average fluorine content of the coal used at a low value of 100 mg/kg, the total annual fluorine emission from steam coal combustion into the atmosphere is estimated to be 66398 t.

    The state of Punjab in the North-West part of India has acted as the main passage for all the major human invasions into the Indian subcontinent. It has resulted in the mixing of foreign gene pool into the local populations, which led to an extensive range of genetic diversity and has influenced the genetic structure of populations in Punjab, North-West India. The present study was conducted to examine the genetic structure, relationships, and extent of genetic differentiation in five Indo-European speaking ethnic groups of Punjab. A total of 1021 unrelated samples belonging to Banias, Brahmins, Jat Sikhs, Khatris, and Scheduled castes were analyzed for four human-specific Ins/Del polymorphic loci (ACE, APO, PLAT, and D1) and three restriction fragment length polymorphisms ESR (PvuII), LPL (PvuII), and T2 (MspI) using Polymerase chain reaction (PCR). All the loci were found to be polymorphic among the studied populations. The frequency of the Alu insertion at APO locus was observed to exhibit the highest value (82.6-96.3 %), whereas D1 exhibited the lowest (26.5-45.6 %) among all the ethnic groups. The average heterozygosity among the studied populations ranged from 0.3816 in Banias to 0.4163 in Khatris. The FST values ranged from 0.0418 to 0.0033 for the PLAT and LPL loci, respectively, with an average value being 0.0166. Phylogenetic analysis revealed that Banias and Khatris are genetically closest to each other. The Jat Sikhs are genetically close to Brahmins and are distant from the Banias. The Jat Sikhs, Banias, Brahmins, and Khatris are genetically very distant from the Scheduled castes. Overall, Uniform allele frequency distribution patterns, high average heterozygosity values, and a small degree of genetic differentiation in this study suggest a genetic proximity among the selected populations. A low level of genetic differentiation was observed in the studied population groups indicating that genetic drift might have been small or negligible in shaping

    Noma (cancrum oris, stomatitis gangrenosa) is a quickly spreading orofacial gangrene in children, caused by a combination of malnutrition, debilitation because of concomitant diseases (measles) and intraoral infections. The global incidence of noma in the world is uncertain. By comparing large numbers of noma patients and cleft lip patients in a large referral hospital for these disorders in Sokoto, Nigeria, we calculated the incidence of noma in north-west Nigeria as 6.4 per 1000 children. Extrapolation of this incidence to the developing countries bordering the Sahara Desert (the noma belt of the world) gives an incidence of 25,600 for that region and a global incidence of 30,000-40,000. Noma is a good biological parameter of extreme poverty, and hence a global monitoring system for noma can be justified. Though economic progress is the most effective preventive measure against noma, medical prevention by vaccination programmes against measles should be enhanced as well.

    To estimate the prevalence and causes of hearing impairment in Fundong Health District, North-West Cameroon. We selected 51 clusters of 80 people (all ages) through probability proportionate to size sampling. Initial hearing screening was undertaken through an otoacoustic emission (OAE) test. Participants aged 4+ years who failed this test in both ears or for whom an OAE reading could not be taken underwent a manual pure-tone audiometry (PTA) screening. Cases of hearing impairment were defined as those with pure-tone average ≥41 dBHL in adults and ≥35 dBHL in children in the better ear, or children under age 4 who failed the OAE test in both ears. Each case with hearing loss was examined by an ear, nose and throat nurse who indicated the main likely cause. We examined 3567 (86.9%) of 4104 eligible people. The overall prevalence of hearing impairment was 3.6% (95% confidence interval [CI]: 2.8-4.6). The prevalence was low in people aged 0-17 (1.1%, 0.7-1.8%) and 18-49 (1.1%, 0.5-2.6%) and then rose sharply in people aged 50+ (14.8%, 11.7-19.1%). Among cases, the majority were classified as moderate (76%), followed by severe (15%) and profound (9%). More than one-third of cases of hearing impairment were classified as unknown (37%) or conductive (37%) causes, while sensorineural causes were less common (26%). Prevalence of hearing impairment in North-West Cameroon is in line with the WHO estimate for sub-Saharan Africa. The majority of cases with known causes are treatable, with impacted wax playing a major role. © 2017 John Wiley & Sons Ltd.

    To ascertain the association between soya consumption, isoflavone intakes and oesophageal cancer risk in remote north-west China, where the incidence of oesophageal cancer is known to be high. Case-control study. Information on habitual consumption of soya foods and soya milk was obtained by personal interview. The intakes of isoflavones were then estimated using the US Department of Agriculture nutrient database. Logistic regression analyses were performed to assess the association between soya consumption, isoflavone intakes and oesophageal cancer risk. Urumqi and Shihezi, Xinjiang Uyghur Autonomous Region, China. Participants were 359 incident oesophageal cancer patients and 380 hospital-based controls. The oesophageal cancer patients consumed significantly less (P soya foods (mean 57·2 (sd 119·0) g/d) and soya milk (mean 18·8 (sd 51·7) ml/d) than the controls (mean 93·3 (sd 121·5) g/d and mean 35·7 (sd 73·0) ml/d). Logistic regression analyses showed an inverse association between intake of soya products and the risk of oesophageal cancer. The adjusted odds were OR = 0·33 (95 % CI 0·22, 0·49) and OR = 0·48 (95 % CI 0·31, 0·74) for consuming at least 97 g of soya foods and 60 ml of soya milk daily (the highest tertiles of consumption), respectively, relative to the lowest tertiles of consumption. Similarly, inverse associations with apparent dose-response relationships were found between isoflavone intakes and oesophageal cancer risk. Habitual consumption of soya products appears to be associated with reduced risk of oesophageal cancer in north-west China.

    2013-02-01

    Seismic hazard assessment of any region depends on the attenuation relation which relates the seismological data with parameters of engineering interest. In the absence of sufficient strong motion data for northwest Himalayan region, isoseismal maps of previous earthquakes were the only source of information for computing the attenuation characteristics of that region. The northwest Himalayan region had experienced major and moderate earthquakes in the past and isoseismal maps had been developed by various authors for each of these earthquakes representing intensity pattern and decay of intensity in different directions. With this information, attenuation relations of intensity with distance can be obtained. The present study includes 10 moderate and major earthquakes ( ≥ 4.9) that had occurred during the last 100 years. These are primarily Kangra (1905), Chamba-1 (1945), Chamba-2 (1995), Kinnaur (1975), Dharamsala (1986), Uttar Kashi (1991), Garhwal-1 (1996), Garhwal-2 (1996), Sundarnagar (1997) and Chamoli (1999) earthquakes. Miezoseismal zones in majority of the isoseismal maps show two major directions, i.e., either the longest axis of these isoseismal maps which are aligned in NW–SE direction following the major longitudinal features or north-northwest to south-southeast direction, following the tectonic features which are transverse to the Himalayan trend. Isoseismal maps of Kangra (1905), Chamba (1945) and Uttar Kashi (1991) earthquakes are more symmetrical and elongated in south-east direction, but compressed in north-east and north-west directions, thus indicating fast attenuation characteristics in north-east and north-west directions reflecting lithological variation. On the other hand, Sundernagar (1997) and Kinnuar (1975) earthquakes show circular pattern of intensity distribution. Combining decay patterns from different magnitude earthquakes in different directions, two attenuation relationships have been developed using regression relationship

    Full Text Available This article analyses population changes in North-West regions of Russia (the former North-Western economic zone and the Kaliningrad region and the Baltics at the level of urban districts and municipalities. The cohort component method is used to analyze the youth population dynamics in the administrative territorial units of this level, which makes it possible to estimate the international (intraregional migration of this population group. This method is used quite rarely, yet it is more accurate in studying the shifts in distribution of this group of population than current statistics. The article uses the data of the last two censuses (2000 and 2010, namely, the population size and the age and gender composition. In order to demonstrate the core-periphery relationship, the authors identified the core ATUs (national and regional capitals and capital areas, whereas the other units were grouped by their remoteness from the center. The analysis shows that in the countries and regions studied, population concentrates in the capitals and capital areas, whereas the periphery loses population at a fast rate. The centripetal movement is especially pronounced with the youth; moreover, it affects not only the size but also its structure of population in the core and periphery areas, which aggravates the processes of depopulation and ageing.

  11. Wind farms and mires in the Basque Country and north-west Navarra, Spain

    Full Text Available Mires occur in the Basque Country and north-west Navarra (northern Spain due to the Atlantic influence on climate. They are most frequent in the north and become rarer to the south. True peatland is found at only six locations, but there are also some para-peaty habitats associated with springs and flushes which have very thin discontinuous peat layers. Although small, this mire territory straddles the boundary between two separate autonomous communities where different regulations and management guidelines apply. Both communities have developed extensive plans to exploit wind energy, and the summit ridges of many of the mountain ranges now carry long strings of turbines. Consequences for the Basque and Navarran mire ecosystems are reviewed. Because little is known about these habitats, they went largely unnoticed during the process of wind farm planning and were thus exposed to enormous risk. Nonetheless, the impacts of development so far have been limited by careful practice combined with the fact that the locations of most of the mires do not coincide exactly with the favoured locations for wind turbines. The only blanket bog is situated in the Zalama area, where plans to build a wind farm have been abandoned for a combination of reasons. Paradoxically, the wind farm planning process was instrumental in raising social and political awareness of this important peatland, leading to a very promising level of interest in its conservation and restoration amongst local institutions.

  12. Modelling the impacts of projected future climate change on water resources in north-west England

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Over the last two decades, the frequency of water resource drought in the UK, coupled with the more recent pan-European drought of 2003, has increased concern over changes in climate. Using the UKCIP02 Medium-High (SRES A2 scenario for 2070–2100, this study investigates the impact of climate change on the operation of the Integrated Resource Zone (IRZ, a complex conjunctive-use water supply system in north-western England. The results indicate that the contribution of individual sources to yield may change substantially but that overall yield is reduced by only 18%. Notwithstanding this significant effect on water supply, the flexibility of the system enables it to meet modelled demand for much of the time under the future climate scenario, even without a change in system management, but at significant expense for pumping additional abstraction from lake and borehole sources. This research provides a basis for the future planning and management of the complex water resource system in the north-west of England.

    Archaeological deposits from Boodie Cave on Barrow Island, northwest Australia, reveal some of the oldest evidence for Aboriginal occupation of Australia, as well as illustrating the early use of marine resources by modern peoples outside of Africa. Barrow Island is a large (202 km2) limestone continental island located on the North-West Shelf of Australia, optimally located to sample past use of both the Pleistocene coastline and extensive arid coastal plains. An interdisciplinary team forming the Barrow Island Archaeology Project (BIAP) has addressed questions focusing on the antiquity of occupation of coastal deserts by hunter-gatherers; the use and distribution of marine resources from the coast to the interior; and the productivity of the marine zone with changing sea levels. Boodie Cave is the largest of 20 stratified deposits identified on Barrow Island with 20 m3 of cultural deposits excavated between 2013 and 2015. In this first major synthesis we focus on the dating and sedimentology of Boodie Cave to establish the framework for ongoing analysis of cultural materials. We present new data on these cultural assemblages - including charcoal, faunal remains and lithics - integrated with micromorphology, sedimentary history and dating by four independent laboratories. First occupation occurs between 51.1 and 46.2 ka, overlapping with the earliest dates for occupation of Australia. Marine resources are incorporated into dietary assemblages by 42.5 ka and continue to be transported to the cave through all periods of occupation, despite fluctuating sea levels and dramatic extensions of the coastal plain. The changing quantities of marine fauna through time reflect the varying distance of the cave from the contemporaneous shoreline. The dietary breadth of both arid zone terrestrial fauna and marine species increases after the Last Glacial Maximum and significantly so by the mid-Holocene. The cave is abandoned by 6.8 ka when the island becomes increasingly distant

    In this study, the association between wintertime temperature anomalies over Northwest China and the weather regime transitions in North Atlantic on synoptic scale is analyzed by using observational surface air temperature (SAT) data and atmospheric reanalysis data. Daily SAT anomaly and duration time are used in order to define SAT anomaly cases. Differences with regard to the circulation anomalies over the Ural Mountains and the upstream North Atlantic area are evident. It is found that the colder than normal SAT is caused by the enhanced Ural high and associated southward flow over Northwest China. Time-lagged composites reveal possible connections between the SAT anomalies and the different development phases of the North Atlantic Oscillation (NAO). The Ural highs tend to be strengthened during the negative phase of NAO (NAO-) to Atlantic ridge transition, which are closely related to the downstream-propagating Rossby wave activity. The opposite circulation patterns are observed in the warm SAT cases. A cyclonic circulation anomaly is distinctly enhanced over the Urals during the positive phase of NAO (NAO+) to Scandinavian blocking transition, which would cause warmer SAT over Northwest China. Further analyses suggest that the intensified zonal wind over North Atlantic would favor the NAO- to Atlantic ridge transition, while the weakened zonal wind may be responsible for the transition between NAO+ and Scandinavian blocking.

    Full Text Available The aim of this article is to contribute to the theoretical evaluation of the EU Cohesion Policy 2007-2013 through a specifi c program – REGIO - Regional Operational Program (ROP and a specifi c region – North-West Region of Romania (NWRR and to identify the obstacles encountered by the benefi ciaries from the public sector that lead to the weak absorption of ROP, in all areas of intervention: urban growth poles, transport infrastructure, social infrastructure, development of business environment, sustainable development and promotion of tourism. Our main concern was to analyze through quantitative and qualitative research the problems identifi ed on the basis of the document analysis and secondary data research, at the level of 176 projects completed by 53 public sector benefi ciaries, fi nanced by ROP 2007-2013, in NWRR, until 31.01.2014. An on-line questionnaire was applied to the project managers, as well as an open structured interview which was applied to the legal representatives of project benefi ciaries. We conclude that the most important obstacle for the public sector, especially for local public administration, is the public procurement process and that the encountered obstacles are outweighed by the advantages of projects with a positive infl uence on the intention to access EU regional funds in the next programming period.

    Extraintestinal nematodes of the red fox (Vulpes vulpes) are a wide group of parasites that infect wild and domestic carnivores and occasionally humans. Nematodes in the cardiopulmonary system, stomach, urinary apparatus and muscle tissue of 165 red foxes (Vulpes vulpes) from north-west Italy (Liguria and Piedmont) were investigated between 2009 and 2012. Of the cardiopulmonary nematodes, a high prevalence of Angiostrongylus vasorum and Eucoleus aerophilus (syn. Capillaria aerophila) was found, 78.2% and 41.8% respectively; Crenosoma vulpis (15.8%) and Filaroides spp. (4.8%) were also found. Spirocerca lupi (23.5%), Aonchotheca putorii (syn. Capillaria putorii) (8.6%) and Physaloptera spp. (2.5%) were detected in the stomach and Pearsonema plica (syn. Capillaria plica) (56.8%) in the bladder. Eucoleus boehmi (syn. Capillaria boehmi) was also detected in the nasal cavities of one of the two foxes examined. A coprological examination revealed eggs of E. aerophilus, A. putorii, S. lupi, Physaloptera spp. and eggs of intestinal parasites. Filarial worms were absent in all the 165 animals examined, nor was there evidence of Trichinella spp. in any of the foxes. The foxes were found to host a high prevalence of many species of extraintestinal nematodes. The prevalence of A. vasorum in foxes found in the present study is among the highest in Europe. In addition, to the best of our knowledge, E. boehmi and Filaroides spp. have never been reported before in this host in Italy.

    Full Text Available Since 2004 Halji Village, home of the oldest Buddhist Monastery in north-west Nepal has suffered from recurrent Glacial Lake Outburst Floods (GLOFs. Studies of recent satellite images identified a supra-glacial lake, located at a distance of 6.5 km from the village, as a possible source of the flood. During a field survey in 2013, the finding was confirmed and several entrances to en-glacial conduits which are draining the lake were found. The topography of the lake basin was then mapped by combining Differential Global Positioning System (DGPS measurements with a Structure From Motion (SFM approach from terrestrial photographs. From this model the maximum filling capacity of the lake has been estimated as 1.06 × 106 m3 with a maximum discharge of 77.8 m3 s−1 calculated using an empirical relation. The flooded area in the valley has been estimated by employing a raster-based hydraulic model considering six scenarios of discharge volume and surface roughness. To understand the changes in glacier geometry in the last decade the thinning and retreat of Halji Glacier have been analysed by geodetic mass balance measurements and a time series of satellite images respectively. The GLOF occurrences have further been correlated with cumulative temperature and cumulative liquid precipitation calculated from the High Asia Reanalysis (HAR dataset. Finally, effective mitigation measures and adaption strategies for Halji village have been discussed.

    This study addresses the coupling between wind wave and circulation models on the example of the Atlantic - European North-West Shelf (NWS). This topic reflects the increased interest in operational oceanography to reduce prediction errors of state estimates at coastal scales. The uncertainties in most of the presently used models result from the nonlinear feedback between strong tidal currents and wind-waves, which can no longer be ignored, in particular in the coastal zone where its role seems to be dominant. Coupled circulation (NEMO) and wave model (WAM) system was used to study the effects of surface ocean waves on thermohaline distribution and ocean circulation at the NWS. Four scenarios - including Stokes-Coriolis force, sea-state dependent energy flux (additional turbulent kinetic energy due to breaking waves), sea-state dependent momentum flux and the combination of the three wave-induced forcing were performed to study the role of the wave-induced processes on model simulations. The individual and collective role of those processes is quantified and the results are compared with the NWS circulation model results without wave effects as well as against various in-situ measurements. The performance of the forecasting system is illustrated for the cases of several extreme events. The improved skills resulting from the new developments in the forecasting system, in particular during extreme events, justify further enhancements of the coastal operational systems. The study is performed in the frame of the COPERNICUS CMEMS Service Evolution Projects Wave2NEMO and OWAIRS.

    Full Text Available The aim of the study was to assess whether the Aggression Replacement Training (ART programme is effective in increasing social skills and decreasing problem behaviour. The sample consisted of 232 children (mean age 10.9 yrs, SD = 2.32, their parents and teachers. The study had a quasi-experimental design with intervention and control groups. Children were recruited from six schools and four social institutions from four regions in North-West Russia from 2010 to 2013. Social skills and externalizing behaviour were assessed with the Social Skills Rating Scale and analyzed by repeated measures ANOVA (GLM. In a pre and post-test assessment, the 30-hour ART programme was associated with a significant increase in social skills when assessed by children’s self-reports. The most reliable effects of the intervention were demonstrated in the two age groups of 6-9 and 10-14 years old. When both pre and post-test were assessed by parents and teachers, children from both the intervention and control groups demonstrated more social skills and less problem behaviour. Overall results point to a significant improvement of social skills among children from the intervention groups, but an improvement in social skills and reduction of problem behaviour have also been indicated among children from the control group. Findings are discussed in view to possible diffusion of treatment from children participating in an intervention to children from control groups.

    Full Text Available A cross sectional study was carried out from October 2010 to March 2011 at Andassa Livestock Research Center, North-West Ethiopia. The objective was to determine the prevalence of cattle flukes infection. Faecal samples were collected from a total of 384 cattle, cross breed (n= 39 and Fogera breed (n=345 of all age groups and sex. Sedimentation technique was employed for the recovery of fluke eggs from freshly collected fecal sample. The results indicated that the overall prevalence of bovine flukes infection was 60.42%. In this study, the highest prevalence was recorded from Paramphistomosis (45.83% followed by Fasciolosis (23.96%, and Schistosomosis (9.89%. The prevalence of flukes infection was higher in age group 1- 2 years old. There was significant difference in case of Paramphistomosis among age groups. No significant association was found between crossed breeds and sex groups for fluke’s infection. The prevalence of Paramphistomosis was high in cross breed (58.97% than Fogera breed (44.35%. However, in both cases, there was no significant difference. The result of the present study revealed that the prevalence of major bovine fluke infection in the study area was relatively low and is the definite proof of active infection.

    Full Text Available Despite alarming statistics on cystic echinococcosis (CE in humans and the importance of dog and ruminant populations, no epidemiological investigations have been performed on CE in Sidi Kacem Province (North-West of Morocco. A part of large research project was devoted to determine the status of CE in ruminants. This paper reports the results of the investigations carried out in the 10 abattoirs of this region, over four successive years (April 2009–March 2013. A total of 1,302 sheep, 652 head of cattle, and 136 goats were postmortem examined and hydatid cysts were collected and examined. The overall CE prevalence of infection was 42.9% in cattle, 11.0% in sheep, and 1.5% in goats. The prevalence shows significant association with age in sheep and cattle; sheep above 3 years and cattle above 5 years are highly infected (64.0% and 72.2%, resp.. Only liver and lungs are found to be infected. Molecular analyses identified G1, G2, and G3 of E. granulosus sensu stricto in liver and lung samples. Cyst fertility was significantly higher in sheep (54.9% than in cattle (50.3%. These findings suggest that control measures should target not only sheep but also cattle.

    West Nile fever (WNF) or West Nile disease (WND) is a mosquito-borne viral disease that can affect birds, humans and horses. West Nile virus (WNV) is a member of the genus Flavivirus in the family Flaviviridae. WNV is maintained in a mosquito-bird-mosquito transmission cycle, whereas humans and horses are considered dead-end hosts. In human and horses, symptoms range from unapparent infection to mild febrile illness, meningitis, encephalitis or death. WNV has a wide geographical range that includes portions of Europe, Asia, Africa, Australia (Kunjin virus), and in North, Central and South America. Migratory birds are thought to be primarily responsible for virus dispersal, including reintroduction of WNV from endemic areas into regions that experience sporadic outbreaks (Fields Virology, 2001, Lippincott Williams and Wilkins, Philadelphia, Pennsylvania, USA, 1043-1125). The occurrence of disease in humans and animals along with birds and mosquitoes surveillance for WNV activity demonstrates that the virus range has dramatically expanded including North, Central and South America as well as Europe and countries facing the Mediterranean Basin. WND infection in humans has been reported in Morocco in 1996 (Virologie, 1, 1997, 248), in Tunisia in 2007 (Ann. N. Y. Acad., 951, 2001, 117) (Med. Trop., 61, 2001, 487) and 2003 (Epidémiologie de la fièvre West Nile, 2012, Thèse de doctorat, Université Montpellier II, Sciences et techniques du Langueduc, Montpellier, France), and in Algeria in 1994 (Rev. Sci. Tech., 31, 2012, 829). Outbreaks of equine encephalitis have been also reported in Morocco in 1996 (Bull. OIE, 11, 1996, 867), in 2003 (Emerg. Infect. Dis., 11, 2005, 306) and in 2010 (World Animal Health Information Database. WAHID, 2010). Serological evidence of WNV has been demonstrated in the three countries in many species. The aim of this review was to assess the epidemiological situation of WND in north-west Africa comprising Morocco, Algeria and Tunisia, with

Study design 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. Results 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. Conclusion 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 Little is known regarding the keeping of animals in the Moretele 1 area of North-West Province, South Africa. Therefore, the status and dynamics of animal husbandry, as well as a general assessment of the needs of animal owners in this area were researched. Results of the investigation will be used to make recommendations for improved veterinary extension servicing in the area. Semi-structured interviews, based on discussions with relevant stakeholders in the community and a resultant problem conceptualisation, were undertaken at 266 randomly selected households in 51 villages and centres in the area, after which the data was checked and verified before being captured and analysed. The findings reveal that within the field of veterinary extension delivery: 1 there is a demand for visual and written extension material, 2 the extension services must function where clients reside, 3 limitations in terms of infrastructure are present and should be addressed through partnerships and coordination amongst all the role-players in the Moretele 1 area, and 4 cattle and poultry are the most important of the animal species and should be the focus points of extension, but the need to curb zoonotic disease should not be disregarded. In this regard veterinary clinics, private veterinarians and other role-players should be used in partnership with extension workers. Lastly, the veterinary clinic is regarded as helpful in many respects by the community consulted and the service should be upgraded and made available to a wider client base, especially where private and state veterinarians are unavailable or too expensive in such resource-limited communities.

  15. Biosecurity on cattle farms: a study in north-west England.

    Marnie L Brennan

    Full Text Available BACKGROUND: Few studies have considered in detail the range of biosecurity practices undertaken on cattle farms, particularly within the UK. In this study, 56 cattle farmers in a 100 km² area of north-west England were questioned regarding their on-farm biosecurity practices, including those relating to animal movements, equipment sharing and companies and contractors visiting the farms. METHODOLOGY/PRINCIPAL FINDINGS: There was great variation between farms in terms of the type of, and extent to which, biosecurity was carried out. For example, the majority of farmers did not isolate stock bought onto the farm, but a small proportion always isolated stock. Many farmers administered treatments post-movement, primarily vaccinations and anthelmintics, but very few farms reported carrying out any health checks after moving animals on. In addition, there appeared to be much variation in the amount of biosecurity carried out by the different companies and contractors visiting the farms. Deadstock collectors and contracted animal waste spreaders, although likely to have a high potential for contact with infectious agents, were reported to infrequently disinfect themselves and their vehicles. CONCLUSIONS/SIGNIFICANCE: These findings suggest that although certain biosecurity practices are undertaken, many are carried out infrequently or not at all. This may be due to many factors, including cost (in time and money, lack of proven efficacies of practices and lack of relevant education of veterinary surgeons, producers and other herd health specialists. Further research exploring the reasons for the lack of uptake is imperative if preventive medicine is to be utilised fully by the farming industry.

    Full Text Available Background: South Africa is reported to have the highest rate of sexual assault in the world with over 40% of cases occurring among children. Children who are sexually abused have support programmes and policies to assist them in coping, but there are no support programmes for mothers or caretakers. Caretakers need support for themselves and assisting them will incrementally benefit children under their care. Often mothers of these children experience shock, anger, disbelief and suffer secondary trauma such as depression and post-traumatic stress disorder (PTSD following their children’s sexual abuse disclosure and yet there are no guidelines for support to these mothers within North-West province (NWPObjectives: The study seeks to develop guidelines for support to mothers of sexually abused children in NWP.Methods: Concurrent convergence triangulation mixed method design was employed in this study. The population consisted of mothers of sexually abused children (SAC (n = 17 participants for the qualitative component and n = 180 participants for the quantitative component. A sample of mothers of SAC was purposely selected.Results: The participants indicated significant levels of depression because of lack of support by stakeholders. Guidelines for support to assist mothers cope with their secondary trauma were developed based on the literature review, study findings as well as an ecological model of the impact of sexual assault on women’s mental health. The results also showed extreme PTSD (47.8%, little support (38.8%, not coping (76.1% and depression (36.1%.Conclusion: The stakeholders should consider a positive approach to support mothers whose children are sexually abused.

    Full Text Available Abstract Background Contraception is a major component of reproductive health. Assessing the levels of contraceptive awareness and use helps to identify potential areas of intervention. Hence, this study was conducted to assess awareness, practice and associated factors of modern contraceptives among street women in North-West Ethiopia. Methods A cross-sectional study was conducted on 204 street women from Gondar and Bahir Dar cities. Participants were recruited from “cluster” sites such as main road sides, isolated slum areas, around Churches and/or Mosques (in the mornings of Sundays and other religious feast days and streets where street women usually reside and/or sleep. Data were collected using a pre-tested and structured interview questionnaire in local language (Amharic after informed verbal consent. Data were then entered into SPSS version 16.0 for analysis. Binary logistic regression models were fit to assess associations and control confounding. Associations were measured by the Odds ratio and its 95% confidence interval. Results The mean (±SD age of participants was 30.9 (± 8.7 years. Majority (90.7% had ever heard about modern contraceptives. Nearly half (47.1% had ever used and a third (34.3% were current users. Three quarter of the current users (74.3% were using injectables while 10% were on long acting or permanent methods. Marital status (AOR=2.81, family size (AOR=2.67 and age of 25–34 years (AOR=3.45 were associated with modern contraceptive use. Conclusions Current contraceptive use among street women is satisfactory considering their life styles and living conditions. However, further research is required to explain perceptions and hidden barriers.

    Large volumes of trachyandesitic-dacitic lava flows and pyroclastics of Miocene age are associated with small volumes of alkali basalt lava flows in the Galatia volcanic province, northwest Central Anatolia, Turkey. The volcanism postdates continental collision, occurring in a transtensional tectonic setting associated with movement along the North Anatolian Fault zone. Major and trace element (including REE) and Sr-Nd isotope data and K-Ar ages for representative samples of mafic-intermediate volcanic rocks have been obtained from a series of localities within the province. The K-Ar age data indicate that alkali basalts were erupted during two distinct time periods in the Early Miocene (17-19 Ma) and Late Miocene (< 10 Ma). The two groups of basalts are inferred to have been derived from different mantle sources, based on their Sr-Nd isotope and geochemical characteristics. The Late Miocene basalts were derived from a more depleted mantle source than the Early Miocene basalts, which were generated by partial melting of an incompatible element enriched, subduction-modified, mantle source. The depleted source component is inferred to reside within the asthenosphere and has some affinities with the source of HIMU oceanic island basalts. On the basis of a comprehensive major and trace element and Nd-Sr isotope dataset for the intermediate-acid volcanics and the alkali basalts, it is possible to demonstrate a cogenetic relationship between the alkali basalts and the intermediate volcanics of Early Miocene age, involving fractional crystallisation and assimilation of a heterogeneous upper crustal component.

    The Regional Ocean Modeling System (ROMS) was applied to the Australian North-West Shelf (NWS) to hindcast the ocean response to four intense historical tropical cyclones (TCs). While the four cyclones had very different trajectories across the NWS, all passed within 150 km of a long-term vertical mooring located on the continental shelf in 125 m depth. The observed ocean response at this relatively shallow, Southern Hemisphere shelf site was characterized by the development of a peak in the counter-clockwise (CCW) near-inertial kinetic energy, mixed layer deepening, and subsequent restratification. Strong near-inertial isotherm oscillations were also observed following two of the cyclones. ROMS reproduced these features and also showed that the peak in the near-inertial CCW kinetic energy was observed on the left side of each cyclone trajectory. The time rate of change of near-inertial kinetic energy depended strongly on the storm Rossby number, i.e., defined based on the storm speed, the storm length scale, and the Coriolis frequency. The shallow water depth on the NWS resulted in first, a more rapid decay of near-inertial oscillations than in the deep ocean, and second a generation efficiency (the ratio of near-inertial power to the rate of wind work) of up to 10%, smaller than found for cyclones propagating across deeper water. The total energy put into near-inertial motions is nevertheless large compared to the background tidal energy. The rapid decay of near-inertial motions emphasizes the importance of frictional effects in characterizing the response to cyclone forcing in shallow seas.

    Full Text Available Orientation: Multiculturalism seemed to have become the dominant strategy for dealing with pluralism in the South African public sphere.Research purpose: The authors addressed the relationship between conditions that are considered to be conducive to multiculturalism and the practices perceived to accomplish this, vis-à-vis multiculturalism and well-being, as measured by ill-health and subjective work success.Motivation for the study: Although multiculturalism has been recommended as an effective way of dealing with diversity at societal and local levels, little is known about its effects in the workplace.Research design, approach and method: Following a quantitative approach, the authors utilised a cross-sectional design with a convenience sample of 241 Black employees and White employees from a mine in North-West Province for the research. Exploratory factor analyses and Cronbach alpha coefficients were used to test scale validity and reliability. Multivariate Analysis of Variance (MANOVA and effect sizes were used to determine the effect of race on the experiences of miners, and multigroup path analysis (AMOS was used to investigate whether or not identical relations between multiculturalism, work success, and ill-health could be found for Black employees and White employees.Main findings: Multiculturalism and mainstream tolerance coupled with ethnic integration demands at home and at work were associated with success at work but not with ill-health. Black employees experienced the workplace slightly more positively.Practical/managerial implications: Multiculturalism and integration are related to subjective experiences of work success and, as such, should be supported in the workplace.Contribution/value-add: Our findings suggest that multiculturalism is relatively well supported by both groups in the workplace. This positive finding should not be regarded as obvious because empirical research has suggested that the majority of members of

    Full Text Available Background: Sexual violence against children is increasing at an alarming rate in South Africa. In 2010 the South African Police Service (SAPS reported 21 538 rape cases of children under 18 years. In the North-West province (NWP 5039 incidents of rape cases were reported in 2009. Mothers often experience emotional pain following child sexual abuse disclosure. It is seldom acknowledged that these mothers experience trauma and need support, post disclosure. The researcher has no known evidence of research conducted on the experiences of these mothers in NWP. Objective: The objective of the study was to explore and describe the experiences of mothers of sexually abused children post disclosure of the abuse. Method: The research design was qualitative, exploratory, descriptive and contextual. Purposive sampling was used to select mothers of sexually abused children aged 23 to 59 years whose children ranged from 0 to 16 years. Permission to conduct the study was sought from the Provincial Department of Health and informed consent was obtained from the mothers. Interviews were conducted with a sample of n = 17 until data saturation. Data were collected through in-depth interviews using a voice recorder and field notes to enhance triangulation. Tesch’s method of open coding was used to analyse data. Results: Findings indicated that mothers experienced emotional pain post sexual abuse. They expressed shock, anger and guilt for not noticing the abuse. They showed significant depression as a result of lack of support by stakeholders. Conclusion: Mothers experienced secondary trauma that poses social and psychological challenges with far-reaching implications.

    One of the major challenges scientists, practitioners and stakeholders are nowadays involved in, is to provide the worldwide population with reliable water supplies, protecting, at the same time, the freshwater ecosystems quality and quantity. Climate and land use changes undermine the balance between water demand and water availability, causing alteration of rivers flow regime. Knowledge of hydro-climate variables temporal and spatial variability is clearly helpful to plan drought and flood hazard mitigation strategies but also to adapt them to future environmental scenarios. The present study relates to the coastal semi-arid Tafna catchment, located in the North-West of Algeria, within the Mediterranean basin. The aim is the investigation of streamflow and rainfall indices temporal variability in six sub-basins of the large catchment Tafna, attempting to relate streamflow and rainfall changes. Rainfall and streamflow time series have been preliminary tested for data quality and homogeneity, through the coupled application of two-tailed t test, Pettitt test and Cumsum tests (significance level of 0.1, 0.05 and 0.01). Subsequently maximum annual daily rainfall and streamflow and average daily annual rainfall and streamflow time series have been derived and tested for temporal variability, through the application of the Mann Kendall and Sen's test. Overall maximum annual daily streamflow time series exhibit a negative trend which is however significant for only 30% of the station. Maximum annual daily rainfall also e exhibit a negative trend which is intend significant for the 80% of the stations. In the case of average daily annual streamflow and rainfall, the tendency for decrease in time is unclear and, in both cases, appear significant for 60% of stations.

    Leptospirosis is a neglected zoonosis of global importance with a complex epidemiology that affects humans, domestic and wild mammals. However, due to the diversity of clinical signs and difficulties of establishing a confirmatory laboratory diagnosis, the disease remains poorly investigated, particularly in the developing world. In Morocco, a descriptive study of the seroprevalence of Leptospira infection in animals has never been undertaken. To fill this gap, the current study was conducted on a subset of animals in north-west Morocco as a preliminary step towards understanding the epidemiological patterns of animal leptospirosis in the country. The study was conducted on 289 serum samples collected between January and April 2012 from dogs, cattle, sheep, goats and donkeys in the areas of Rabat-Temara, Sidi Kacem and Oulmes. All serum samples were tested by the MAT with 14 reference strains of the most prevalent pathogenic serovars of Leptospira and two serovars of non-pathogenic Leptospira. The overall seroprevalence of Leptospira in cattle, sheep, goats, dogs and donkeys was 15%, 18%, 20%, 21% and 20%, respectively. The most prevalent serogroups found in each species were Ballum, Sejroe, and Australis in cattle, Ballum, Australis and Sejroe in sheep, Australis and Ballum in goats, Javanica and Australis in donkey and Australis, Ballum and Canicola in dogs. Of all the serogroups tested in this study, Icterohaemorrhagiae, the only serogroup which has been previously reported in humans in Morocco, was rarely reactive. The majority of reactive sera were collected from low land areas. A large number of sera samples classified as seronegative when tested against pathogenic leptospires were positive when tested against non-pathogenic leptospires; this is suggestive of possible novel, as yet unclassified, Leptospira serovars in Morocco. Eleven of thirteen sheep urine samples were positive by real-time PCR confirming their role as Leptospira carriers in Morocco.

    Full Text Available Validation of Several Atmospheric Stability Indices for the Storms Generating Torrential Rain Showers in the North-West of Romania. The present study deals with the atmospheric instability types that lead to torrential rain formation in the North-Western part of Romania and with the role that certain stability indices play in establishing the atmospheric instability potential. 35 years of warm season rainfall data from 14 meteorological stations in the North-West of Romania have been analysed in this respect. The Hellman criterion was employed in order to establish the torrential character of the rainfall events, having made use of 271 of such rainfall events in the analysed period (1975-2009. Considering that the synoptic context of the torrential rain occurrence differs according to the instability type existing at the moment of their apparition, the analysis of the stability indices has taken this feature into consideration as well. Hence, three types of instability have been identified (convective lifting, frontal lifting and that produced due to the “cut off” nuclei their analysis underlining the highest frequency of torrential rains caused by the convective lifting (49.1%, followed by the frontal type (27.7% and the ‘cut off” type (23.2%, their highest percentage being registered in the summer. The values of 5 stability indices have been taken into account (KI, VT, CT, TTI and LI, determined on the basis of the aerologic survey at 00 GMT time, undertaken in Cluj-Napoca, plus two more modified indices (KMOD and TTMOD. Having analysed them, it was possible to identify the most useful ones for determining the convective storms conditions generating torrential rains in the North-West region of Romania.

    The MERRA Aerosol Reanalysis (MERRAero) has been recently developed at NASA's Global Modeling Assimilation Office (GMAO). This reanalysis is based on a version of the GEOS-5 model radiatively coupled with GOCART aerosols, and it includes assimilation of bias-corrected Aerosol Optical Thickness (AOT) from the MODIS sensor on both Terra and Aqua satellites. Our main finding is that, in October, in the absence of aerosol sources in north-west Bay of Bengal (BoB), MERRAero showed increasing AOT trends over north-west BoB exceeding those over the east of the Ganges basin. The Ganges basin is characterized by significant population growth accompanied by developing industry, agriculture, and increasing transportation: this has resulted in declining air quality. MERRAero data for the period 2002-2009 was used to study AOT trends over north-west Bay of Bengal (BoB) in the early post-monsoon season. This season is characterized by aerosol transport from the Ganges basin to north-west BoB by prevailing winds; and still significant rainfall of over 150 mmmonth. Different aerosol components showed strong increasing AOT trends over north-west BoB. The following factors contributed to the increasing AOT trend over the area in question in October: an increasing number of days when prevailing winds blew from land to sea, resulting in a drier environment and an increase in air pollution over north-west BoB; wind convergence was observed over north-west BoB causing the accumulation of aerosol particles over that region, when prevailing winds blew from land to sea. MERRAero aerosol reanalysis can be used on a global scale.

    A Lagrangian approach based on a physical–biogeochemical modeling was used to compare the potential transfer of cadmium (Cd) from natural and anthropogenic sources to plankton communities (Cd-uptake) in the North-West African upwelling. In this region, coastal upwelling was estimated to be the main natural source of Cd while the most significant anthropogenic source for marine ecosystem is provided by phosphate industry. In our model experiment, Cd-uptake (natural or anthropogenic) in the North-West African upwelling is the result of an interplay between the Cd dispersion (by advection processes) and the simulated biological productivity. In the Moroccan waters, advection processes limit the residence time of water masses resulting in a low natural Cd-uptake by plankton communities while anthropogenic Cd-uptake is high. As expected, the situation is reversed in the Senegalo-Mauritanian upwelling where natural Cd-uptake is higher than anthropogenic Cd-uptake. Based upon an estimate of Cd sources, our modeling study shows, unexpectedly, that the anthropogenic signal of potential Cd-bioaccumulation in the Moroccan upwelling is of the same order of magnitude as the natural signal mainly present in the Senegalo-Mauritanian upwelling region. A comparison with observed Cd levels in mollusk and fishes, which shows overall agreement with our simulations, is confirming our estimates. - Highlights: • We model the physical–biogeochemical dynamics in the North-West African upwelling. • We model the transport of cadmium from natural and anthropogenic sources. • We derive proxies of potential cadmium absorption and bioaccumulation in the plankton food chain. • The anthropogenic signal off Morocco at least equals the natural upwelling signal off Mauritania. • We compare our results with observed cadmium levels in mollusks and fishes.

    Tarim River is one of the longest inland rivers in the world. It flows its water in the northern part of the Taklamakan desert in Xinjiang, North-west of China, which is a very hostile region due its climatic conditions and particularly due to low precipitation and very high evaporation rates. During the past five decades intensive exploitation of water resources, mainly by agricultural activities, has changed the temporal and spatial distribution of them and caused serious environmental problems in the Tarim River Basin. The support measures for oasis management along the Tarim River under climatic and societal changes became the overarching goal of this research. The temperature has risen by nearly 1° C over the past 50 years in the Tarim River Basin so more water was available in the mountainous areas of Xinjiang, leading to an increasing trend of the headstream discharges of the Tarim Basin. Aksu, Hotan and Yarkant Rivers are three tributaries of the Tarim River, as well as its main water suppliers. However, under the condition of water increase with the volume of 25×108 m3 in headstreams in recent 10 years, the water to the mainstream has increased less than 108 m3 (in Alar hydrological station), which is less than 3% of the increased water volume of runoff. Moreover, the region is one of the biggest cotton and other cash crops producers in China. In addition, expansion of urban and, in particular, of irrigation areas have caused higher water consumption at different parts of the river, leading to severe ecological effects on rural areas, especially in the lower reaches. Moreover, it also highly affects groundwater level and quality. The aim of this research is to support decision makers, planners and engineers to find right measures in the area for the further development of the region, as well as adaptation to changing climate. Different scenarios for water resource management, as well as water distribution and allocation in a more efficient and water

    The Windscale nuclear reactor fire at Sellafield, United Kingdom, in October 1957 led to an uncontrolled release of iodine-131 (radioactive half-life, 8 d) into the atmosphere. Contamination from the accident was most pronounced in the counties of Cumbria and Lancashire, north-west England. Radioiodine concentrates in the thyroid gland producing an excess risk of thyroid cancer, notably among those exposed as children, which persists into later life. For an initial investigation of thyroid cancer incidence in north-west England, data were obtained on cases of thyroid cancer among people born during 1929-1973 and diagnosed during 1974-2012 while resident in England, together with corresponding populations. Incidence rate ratios (IRRs), with Poisson 95% confidence intervals (CIs), compared thyroid cancer incidence rates in Cumbria and in Lancashire with those in the rest of England. For those aged  investigations are required to properly understand the unusual patterns of thyroid cancer IRRs in Cumbria and Lancashire, the results of this preliminary study are not consistent with an effect of exposure to iodine-131 from the Windscale accident.

    Full Text Available This paper examines the spatial and temporal development of streamflow droughts in Europe over the last 40 years, differentiating the climatic factors that drive drought formation from catchment controls on drought manifestation. A novel approach for quantifying and comparing streamflow and precipitation depletion is presented. This approach considers atypical flow or rainfall events, as well as more severe droughts, regardless of the season in which they occur (although unlikely to constitute drought in an operational sense, sustained atypical flows are important with regard to understanding how droughts arise and develop. The amount of flow depletion is quantified at daily resolution based on the standardised departure from the mean day d flow, or flow anomaly. The index was derived for 2780 gauging points within north-west Europe using data from the FRIEND European Water Archive for the 1960-1995 period. Using a simple interpolation procedure these data were used to produce a time-series of grids, with a cell size of 18 km2, showing the spatial distribution of flow anomaly over the study area. A similar approach was used to characterise monthly precipitation anomalies, based on existing grid data (see New et al., 2000. The grids were analysed chronologically to examine the spatial and temporal coherency of areas showing large flow and/or precipitation anomalies, focussing on drought development during the 1975-1976 and 1989-1990 periods. Using a threshold approach, in which an anomaly of 2 standard deviations represents the onset of drought conditions, indices were developed to describe the time-varying extent and areal-severity (flow deficit of streamflow and precipitation drought. Similar indices were used to describe how the magnitude and temporal variation of flow depletion varied spatially. In terms of streamflow depletion, the 1976 drought was found to be a highly coherent event, having a well defined start (in January 1976 and end (in

    Full Text Available The largest uncertainty in the radiative forcing of climate change over the industrial era is that due to aerosols, a substantial fraction of which is the uncertainty associated with scattering and absorption of shortwave (solar radiation by anthropogenic aerosols in cloud-free conditions (IPCC, 2001. Quantifying and reducing the uncertainty in aerosol influences on climate is critical to understanding climate change over the industrial period and to improving predictions of future climate change for assumed emission scenarios. Measurements of aerosol properties during major field campaigns in several regions of the globe during the past decade are contributing to an enhanced understanding of atmospheric aerosols and their effects on light scattering and climate.

    The largest uncertainty in the radiative forcing of climate change over the industrial era is that due to aerosols, a substantial fraction of which is the uncertainty associated with scattering and absorption of shortwave (solar) radiation by anthropogenic aerosols in cloud-free conditions (IPCC, 2001). Quantifying and reducing the uncertainty in aerosol influences on climate is critical to understanding climate change over the industrial period and to improving predictions of future climate change for assumed emission scenarios. Measurements of aerosol properties during major field campaigns in several regions of the globe during the past decade are contributing to an enhanced understanding of atmospheric aerosols and their effects on light scattering and climate.

    Full Text Available Abstract Background Antibiotic resistance is a worldwide problem and inappropriate prescriptions are a cause. Especially among children, prescriptions tend to be high. It is unclear how they differ in bordering regions. This study therefore examined the antibiotic prescription prevalence among children in primary care between northern Netherlands and north-west of Germany. Methods Two datasets were used: The Dutch (IADB comprises representative data of pharmacists in North Netherland and the German (BARMER GEK includes nationwide health insurance data. Both were filtered using postal codes to define two comparable bordering regions with patients under 18 years for 2010. Results The proportion of primary care patients receiving at least one antibiotic was lower in northern Netherlands (29.8 %; 95 % confidence interval [95 % CI]: 29.3–30.3, compared to north-west Germany (38.9 %; 95 % CI: 38.2–39.6. Within the respective countries, there were variations ranging from 27.0 to 44.1 % between different areas. Most profound was the difference in second-generation cephalosporins: for German children 25 % of the total prescriptions, while for Dutch children it was less than 0.1 %. Conclusions This study is the first to compare outpatient antibiotic prescriptions among children in primary care practices in bordering regions of two countries. Large differences were seen within and between the countries, with overall higher prescription prevalence in Germany. Considering increasing cross-border healthcare, these comparisons are highly valuable and help act upon antibiotic resistance in the first line of care in an international approach.

    2015-01-01

    Full Text Available Seventeen onion landraces from North-West Spain were evaluated using microsatellites markers. Eleven polymorphic markers identified 32 alleles in the whole collection, with an average of 2.9 alleles per locus. High values of observed (mean of 0.45 and expected heterozigosity (mean of 0.51 were detected for the majority of loci. Wright’s fixation index confirmed an excess of heterozygotes and a low level of inbreeding within the collection. Multivariate analyses revealed that Oimbra was the most distinctive genotype. The remaining 16 onion genotypes were in part assorted according to some morphological traits of bulbs. Pungency and solid soluble content highly varied among landraces and bulbs. Five landraces were classified as sweet, whereas 9 possessed medium pungency and 3 were recorded as pungent. This onion collection represents a useful source of genetic heterogeneity that might be exploited in breeding programs for the generation of new onion varieties that satisfy consumer demands.

    The Populus euphratica floodplain forests along the lower reaches of the Tarim River in continental-arid Xinjiang (north-west China) have been declining in recent decades as a result of dam constructions and the withdrawal of water from the river. Since 2000, controlled flooding has been carried out to counteract this process of degradation. However, the consequences of a changing water regime for the floodplain ecosystem are not yet sufficiently investigated. In 2004 we sampled a total of 150 P. euphratica trees along two transects at the middle and lower reaches of the Tarim River to compare the age structure and growth of these two tree populations. The anthropogenic drawdown of the groundwater table had no effect on the average growth of the trees at the lower reaches. However, tree growth abruptly increased after controlled flooding, thus showing distinct signs of recovery.

    Full Text Available This paper presents the results of the research dedicated to the role of space in the modernization of the economy of the North-West maсro-region of Russia conducted in 2012–2014, within the framework of the Presidium of Russian Academy of Sciences (RAS №31 "The role of space in the modernization of Russia: natural and socio-economic potential." The analysis is based on the methodology, which was developed at the Institute of Regional Economy of RAS. Possibilities of modernization of the Russian economy are due to competitive advantages, "inherited characteristics" and public policy of regions and major macro-regions development. Recourses of modernization have a spatial component, which significantly affects the positioning of the region, its companies, firms and projects in the globalized geo-economic space. It is noted that the characteristics of multi-factor situation, taking into account the “inherited characteristics” of spatial development, the nature of geopolitical and geo-economic situation, transformation of the socio-economic area, evaluation the role of internal and external factors, including the impact of globalization and the state regional policy, as well as assessment of the role of internal spatial inversion of macro-region and innovation potential of regional development mostly define the corridors for modernization of the economy of the regions. It is found that four groups of factors highlighted in this study allow to take into account the wide range of opportunities and constraints for the modernization of the economy of the North-West macro region. On the basis of interdisciplinary synthesis within the geospatial paradigms, taking into account the developments of domestic economists-regionalists, economic geographers and western views in the framework of the space science, the idea of A.

    2015-06-01

    Full Text Available This paper investigates both commune and household determinants of household income among ethnic minorities in the North-West Mountains – the poorest region of Vietnam. The findings show that the vast majority of the sample households heavily depend on agricultural activities. Factors affecting household income per capita are examined using multiple regression models and the findings confirm the important role of education, non-farm employment and fixed assets in improving household income. In addition, some commune variables such as the presence of the means of transportation, post offices and non-farm job opportunities are found to have an increasing impact on household income. The findings suggest that policies for poverty reduction should aim at both commune and household levels. Policies that focus on improving the access of ethnic minorities to education and non-farm employment are expected to be effective ways of enhancing their income.

    Full Text Available Orientation: School principals have an important role to play in the quality of service delivery in schools. Evidence suggests that school principals are generally poorly compensated, which has an adverse impact on their well-being and subsequent service quality orientation.Research purpose: This study investigated whether rewards are a predictor of well-being and service orientation of school principals in the North-West province.Motivation for the study: Effective school principals are fundamental to the success of any school, which necessitates the establishment of an effective reward and remuneration system.Research design, approach and method: Quantitative research was carried out among school principals (N = 155 in four districts of the North-West province. The Total Rewards Scale, Maslach’s Burnout Inventory – General Survey, the Utrecht Work Engagement Scale and the SERVQUAL measure were administered among the principals.Main findings: The results showed that rewards are a significant predictor of the well-being and service quality of school principals. The results further showed that burnout significantly reduces the service quality of school principals. No significant relationships were found between work engagement and the service quality of school principals.Practical/managerial implications: An effective total rewards system enhances the well-being of school principals and, subsequently, their willingness and commitment to delivering quality services.Contribution: The results of this study point out some key elements that need to be considered by the Department of Education to enable quality service delivery in South African schools.

    The aim of this study was to investigate whether the population differences in osteoporosis observed nowadays is a reflection of the times and modern lifestyle factors, or whether they were also present in the past. The study was performed on the skeletal remains of medieval and post-medieval populations from a burial ground in the North-West of Italy. Some individuals had been buried inside the church (privileged subjects), others outside in the parvis (members of rural population), and others still to the north of the church. X-ray, computed tomography and dual-energy X-ray absorptiometry studies were carried out on the lumbar spines and/or femurs of 27 male and 28 female individuals to determine any associations between cortical index, bone mineral density (BMD), gender, age and social status. No statistically significant differences were observed in cortical index values according to gender, age or place of burial. Conversely, statistically significant differences in average BMD values were observed according to place of burial; in particular, among those buried inside the church, a lower BMD was observed compared to the parvis group (1.09 vs. 1.42, p < 0.001) and the north group (1.09 vs. 1.49, p < 0.001). The differences observed in the BMD values may be related to the different lifestyle of the rural population, i.e. more dietary calcium intake, more sun exposure and vigorous physical activity, compared to that of the privileged individuals.

    Russia owns the largest natural gas, the second largest coal and the third largest oil reserves in the world. Russia is the third largest energy user and the largest producer of oil and gas in the world. Export of oil and gas plays a major role in the economic development of the whole Russia. Wood harvesting and processing industry responds only 4,4 % of the industrial production although Russia owns 23 % of the world's forest resources. Biomass represents only 1 % of the total energy consumption including residential use but hydro power represents about 18 % of Russia's electricity generation. Russia needs three times more energy to produce one unit of GDP than e.g. EU. This indicates very poor energy efficiency and poor conditions of the energy and the whole infrastructure as well. Simultaneously the prices of fossil fuels and electricity are heavily subsidized. These basic figures give on idea why utilization of renewable energy and especially biomass play a minor role in Russian energy system. One of the most progressive regions in bioenergy is the Northwest of Russia. The first pellet and briquette plants were installed in this region a few years ago. The region can be regarded as the forerunner in bioenergy in Russia. Federal Region of Northwest Russia consists of City of St.Petersburg, Republics of Karelia and Komi and regions of Leningrad, Arkhangelsk, Kaliningrad, Murmansk, Nenetsk, Novgorod, Pskov and Vologda. The region has 15 million inhabitants and a 2200 km long joint border with the EU, most of that with Finland. N-W Russia owns over 14000 million m3 of raw wood that represents 17 % of Russian forests and 60 % of the forests located in the European side. Potential for annual harvesting is over 100 million m3 while harvesting is about 45 million m3. Most of that is exported as a form of raw wood. Wood represents only 2,8 % of the region's energy use including residential usage. Use of peat is marginal representing only 0,1 % of the

    1997-07-01

    Construction of a stabilized rammed earth wall (SRE), which consists of a mixture of unwashed, unscreened sandy aggregate and cement, reinforced with bamboo and insulated with vermiculite or foam board, was described, and its performance reviewed. Although not popular in Canada in general, rammed earth wall construction is being used for custom homes in British Columbia`s Gulf Islands. France and Australia are also active in the development of rammed earth wall technologies. The base SRE house is 1500 sq ft, single storey slab-on grade, with the long axis oriented east-west. SRE houses have a very long life expectancy, (estimated 100 to 1,000 years). There are no exterior or interior surfaces to be painted, or replaced. The material is highly resistant to mechanical damage. Construction cost is higher than frame wall construction, but maintenance cost, space heating energy cost, environmental impact cost, and local economic benefit are all greater than traditional frame construction (the latter because of the high labour requirement and high local materials component). Insulated rammed earth wall construction is considered to be a technically sound exterior wall system, especially in the milder climate of the Pacific Northwest. Because of the higher thermal mass, a greater passive solar contribution is also expected from a rammed earth house.

    This paper mainly presents analytical results of apatite fission-track ages to constrain the uplifting characteristics of EW-trending range of Northern Altun Mountains. 22 rock mass samples were collected from Zhuoerbulake, Dapinggou, and Kaladawan in EW-trending mountain range of Northern Altun Mountains. Fission-track ages for these samples range from (62.6±3.5) to (28.3±1.7) Ma with mean track lengths varying from (13.25±0.15) to (14.29±0.1)μm. According to track lengths and measured age data, the authors carried out the inversion simulation on temperature and age of apatite. The results show a specific regularity of the uplifting of Northern Altun Mountains. In the SN direction, the fission-track ages display a uplifting trend from south to north. In the EW direction, the ages of Dapinggou area in the middle mountains were older than those of other areas and confined to Paleocene and Eocene, and imply an uplifting trend from the middle outwards. The similar thermal history simulation lines of all samples and the single peak of track lengths are considered to have been caused by rapid uplifting during the Paleocene-Eocene (63~28 Ma) and steadiness during the Miocene and later periods in the Northern Altun Mountains. A comparative study of the uplifting and exhumation of the whole Altun area shows that the mountains uplifting and denudation of this region had both global and unique features in Cenozoic: the uplifting of the Altun Mountains had universality and regional features in Paleogene, but uplifting and exhumation existed in NEE-trending and NE-trending mountain ranges in Miocene and subsequent period. It is held that the rapid strike-slip Altun fault has had no influence on uplifting and denudation of EW-trending mountain ranges in Northern Altun Mountains since Miocene.%本文主要利用磷灰石裂变径迹测年技术探讨了阿尔金北缘EW向山脉隆升的时空差异特征。22个岩体分别采自阿尔金北缘EW向山体中的卓尔布

    The Tula A2-subtype granite pluton is located between the Altun fault and its branching fault.According to the geological, geochemical, REE and trace elements characteristics, it belongs to the A2 (PA) subtype granite. The SHRIMP U-Pb zircon dating gives a result of 385.2+8.1 Ma, which is located between the Middle and Late Devonian in the international stratigraphic chart, and can be regarded as the crystallization age of the Tula granite. The study indicates that the Tula area was in a local extensional environment in the end of the Middle Devonian, and that environment was probably related to the synchronized strike-slip activity of the Altun fault.

    2016-02-01

    Full Text Available Background: Job satisfaction and burnout have been recurring problems amongst nurses in the Republic of South Africa (RSA. As a result, nurses are still leaving the rural public sector in search of lucrative work at the urban and private sectors and in developed countries. Accordingly, Occupational Specific Dispensation (OSD was introduced as a strategy to ircumvent the problem. However, since the implementation of OSD in 2007, there have been no studies conducted regarding the level of job satisfaction amongst nurses after the implementation of OSD in the North-West Province, especially because each province has its own challenges that are unique to the area.Objectives: The study had two objectives: to describe the level of job satisfaction amongstprofessional and other category nurses (OCNs at a public hospital in the North-West Provinceand describe the perceptions of nurses about OSD and their intention to continue working inthe hospital.Method: A quantitative descriptive cross-sectional design was used. Stratified random sampling was used to select a sample of 92 professional nurses (PNs, 90 enrolled nurses and enrolled nursing assistants (Nursing Act 2005, which made a total of 182 participants. For the purpose of the study, the enrolled nurses and enrolled nursing assistants were referred to as OCNs.

    The north-western region of China carries a big burden of esophageal cancer with incidence above the national average. This study ascertained the association between fruit and vegetable consumption and the risk of esophageal cancer in this remote part of China. A case-control study was undertaken in Urumqi and Shihezi, Xinjiang Uyghur Autonomous Region of China, between 2008 and 2009. Participants were 359 incident esophageal cancer patients and 380 hospital-based controls. Information on habitual fruit and vegetable consumption was obtained by face-to-face interview using a validated semiquantitative food frequency questionnaire. Unconditional logistic regression analyses were performed to assess the strength of the associations. The esophageal cancer patients consumed significantly less fruits (mean 364.3, standard deviation [SD] 497.4 g) and vegetables (mean 711.4, SD 727.9 g) daily than their counterparts without the disease (mean 496.5, SD 634.4 g and mean 894.5, SD 746.1 g, respectively). The adjusted odds ratios were 0.48 (95% confidence interval 0.33-0.71) and 0.46 (95% confidence interval 0.32-0.68) for consuming at least 515 g of fruits and 940 g of vegetables per day, respectively, relative to at most 170 g and 520 g. With respect to nutrients contained in fruits and vegetables, intakes of vitamin C, vitamin E, β-cryptoxanthin, potassium, and magnesium at high levels also reduced the esophageal cancer risk. In conclusion, inverse associations were evident between consumption of fruits and vegetables and the risk of esophageal cancer for adults residing in north-west China.

    Full Text Available This paper presents aspects regarding population and workforce in Maramureş County, compared with the situation recorded in the region to which it belongs, i.e. North - West, at the end of 2010. The paper is aimed at all those interested in these issues. Besides Maramureş County, the North - West Region also includes the counties of Bihor (BH, Bistriţa-Năsăud (BN, Cluj (CJ, Satu Mare (SM and Sălaj (SJ. Maramureş is known for its wooden churches, its rural architecture, its old traditions - preserved until today - its craftsmen and its impressive landscapes. This paper is based on statistical information provided by the National Institute of Statistics, Department of Statistics in Cluj. In March 2013, the latest data available are those relating to the end of 2010. Thus, based on this information, it pinpoints the fields in which the people in Maramureş are employed at this date, compared to other counties in the region, the wages they get, and the contribution to the county and regional GDP. It also compares labor resource, active civil population and employed civil population, unemployed. After 1989, Maramureş County, as well as the entire North - West Region, underwent major changes. Population decreased from year to year, however the lack of jobs has become a constant reality. The mining of ore, the processing of metals other than iron and the auto industry, which used to cover most of the jobs in Maramureş, entered into a continuous decline, which culminated in the closure of all mines in the county. In this situation, adapting to the new conditions, the current economic reality, is a daily problem for the people of this county. We will try to determine in which fields the people of Maramureş are currently working in, compared to the residents of the other counties in the region, which are their wages and what the contribution to the regional and county GDP is. We will also see the state of the labor resource, the active civil

    Context: Emergency contraception (EC) is use of drug or device to prevent pregnancy after unprotected sexual intercourse. Unlike other regular methods of contraception which are taken prior to the sexual act, EC is used after the unprotected sex. Aim: To assess the knowledge and attitude toward use of emergency contraceptives among medical students. Setting and Design: A cross-sectional questionnaire based study was conducted among all the medical students in the Government Medical College in North-West India. Subjects and Methods: A questionnaire seeking information on knowledge and attitude of undergraduate medical students was administered over a period of 4 weeks in the month of February and March 2014. Statistical Analysis: The data were entered in MS excel and expressed using percentages. Chi-square test was used as a test of statistical significance. Results: About 61.6% (247/401) of the participants were aware about the timing of use of EC. Audio visual media (76.6%; 307/401) was the most common source of information for of these medical students. Conclusions: The lack of appropriate in-depth knowledge of EC among future health care professional should alarm the medical teaching system as EC is the only method that can be used to prevent pregnancy after unprotected sex or contraceptive accident.

    'A Body Shape Index-Adolescents' (ABSI-Adolescents) and waist-to-height ratio are recently proposed indices that quantify central obesity in adolescents. To investigate the scaling exponents to standardise waist circumference (WC) for body mass index (BMI) and height and to investigate the association between BMI, WC-based indices and cardiometabolic outcomes in adolescents of three ethnic groups. A cross-sectional study of 1755 adolescents (516 Hans, 565 Uygurs, 674 Kazakhs) was conducted in north-west China. Correlation between indices of obesity and blood pressure (BP) and fasting blood glucose (FBG) were estimated and compared. Two ethnic groups (Han and Kazakh) had WC-BMI-height profiles different from the previously proposed ABSI-Adolescents and, therefore, required different scaling exponents for WC standardization. After adjustment for age and gender, WC and BMI have similar associations with BP and FBG. After further adjustment for BMI, WC remained significantly associated with FBG in all three ethnic groups (each p adolescents (each p pressure and fasting blood glucose in adolescents of three ethnicities. The WC-based indices did not out-perform WC per se.

    Full Text Available Background: Cats and other felines act as definitive hosts for many intestinal parasites, some of which are responsible for several zoonotic diseases.  The aim of this study was to determine the type and prevalence of protozoa and gastrointestinal helminthes among stray cats. Methods: A cross sectional study was conducted. Digestive tracts of 100 stray cats in Zanjan Province, north-west of Iran were autopsied in order to recognize gastrointestinal helminthes and intestinal protozoan parasites. These cats were collected by baited cage trapped from October 2007 to September 2008. Gender and species of helminthes and protozoa were rec­ognized using authentic diagnostic criteria. Statistical evaluation was performed by SPSS version 14. Results: Forty-two percent of cats were infected with intestinal protozoan parasites, 33% were infected with cestodes and 39% infected with gastrointestinal nematodes. Four species protozoan parasites and eight gastrointestinal helminthes were recovered from the animals, including Taenia taeniaeformis, Dipylidium spp., Joyeuxiella pasqaulei, Toxocara cati, Phy­saloptera praeputialis, Rectalaria spp., Onicolla, Cystoisospora spp., Toxoplasma gondii, and Sarcocystis spp . Conclusions: The high infection rate of Toxoplasma and some gastrointestinal helminthes in stray cats is considered to be critical from the viewpoint of public health importance.

    Full Text Available Research has shown that health system utilization is low for chronic diseases (CDs other than HIV. We describe the knowledge and perceptions of CDs identified from rural and urban communities in north-west Tanzania and southern Uganda.Data were collected through a quantitative population survey, a quantitative health facility survey and focus group discussions (FGDs and in-depth interviews (IDIs in subgroups of population survey participants. The main focus of this paper is the findings from the FGDs and IDIs.We conducted 24 FGDs, involving approximately 180 adult participants and IDIs with 116 participants (≥18 years. CDs studied included: asthma/chronic obstructive lung disease (COPD, diabetes, epilepsy, hypertension, cardiac failure and HIV- related disease. The understanding of most chronic conditions involved a combination of biomedical information, gleaned from health facility visits, local people who had suffered from a complaint or knew others who had and beliefs drawn from information shared in the community. The biomedical contribution shows some understanding of the aetiology of a condition and the management of that condition. However, local beliefs for certain conditions (such as epilepsy suggest that biomedical treatment may be futile and therefore work counter to biomedical prescriptions for management.Current perceptions of selected CDs may represent a barrier that prevents people from adopting efficacious health and treatment seeking behaviours. Interventions to improve this situation must include efforts to improve the quality of existing health services, so that people can access relevant, reliable and trustworthy services.

    Styrene oligomers (SOs) as global contaminants are an environmental concern. However, little is known on the distribution of SOs in the ocean. Here, we show the distribution of anthropogenic SOs generated from discarded polystyrene (PS) plastic monitored from the coastal ocean surface waters (horizontal distribution) and deep seawaters (vertical distribution) in the North-West Pacific Ocean. SOs concentrations in surface seawater and deep seawater ranged from 0.17 to 4.26 μg L(-1) (total mean: 1.48 ± 1.23 μg L(-1)) and from 0.31 to 4.31 μg L(-1) (total mean: 1.32 ± 0.87 μg L(-1)), respectively. Since there is no significant difference in the mean concentrations, SOs seems to be spread across marine environment selected in this study. Nevertheless, regional SOs appears to persist to varying degrees with their broad horizontal and vertical distribution in the ocean. Each horizontal and vertical distribution of SOs differs by approximately 1.95-2.57 times, probably depending on the events of weather and global ocean circulation. These results provide the distribution pattern of SOs for assessing environmental pollution arising from PS plastic. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This study examines the geographic variability in otolith shape of round sardinella Sardinella aurita as a tool for stock discrimination. Fish were analysed from six sampling locations from Senegal to the Mediterranean coast of Morocco. A combination of otolith shape indices and elliptic Fourier descriptors was investigated by multivariate statistical procedures. Within the studied area, three distinct groups were identified with an overall correct classification of 78%. Group A: Nador (Alboran Sea), group B: Casablanca (northern Morocco) and group C: Senegalese-Mauritanian. The results of this study confirm the absence of an Atlantic Ocean-Mediterranean Sea transition for this species, the Gibraltar Strait acting as an efficient barrier for S. aurita population separation. Off north-west Africa, fish from northern Morocco form a single group which is clearly isolated from Senegalese-Mauritanian waters, confirming the existence of a distinct stock in this area. Among group C, some discontinuity exists and suggests the existence of a sedentary fraction of S. aurita in northern Mauritania (Arguin Bank). The results are discussed in relation to oceanographic features and physical barriers to dispersal and fish management strategy in the study area.

    Full Text Available Background: Homocysteine has been shown to be a risk factor for cardiovascular disease and is a degradation product of sulfur containing amino acids. The aim of this post-hoc analysis was aimed at arriving at homocysteine levels among voluntarily consenting healthy adults in the context of other hematological parameters. Methods: The data for this post-hoc analysis were derived from an observational study carried out at a medical college in rural North-west India. Results: About 77.42% of those participants enrolled in this study having serum homocysteine level more than 30 μmol/L were seen to possess suboptimal serum Vitamin B 12 (<200 pg/ml. On subjecting data to regression analysis, serum homocysteine was observed to possess an inverse correlation with serum level of Vitamin B 12, in general. Conclusions: Hyperhomocysteinemia observed in our study was sufficiently common and wholly ascribable to low Vitamin B 12 concentration as we did not find any case of subnormal serum folic acid level.

    There has been a decline in the population of some bird species at Morecambe Bay and the Solway Firth Special Protected Areas in North-West England during the last fifty years. It was suggested that the declines were caused, in part, by contaminants in the food and environment, primarily from the radioactive effluent discharge from the Sellafield Ltd nuclear fuel reprocessing plant in Cumbria. This study analysed bird feathers and tissues, vegetation and sediment for radionuclides, metals and persistent organic compounds. The non-radionuclide results were all low compared to relevant action limits. The ERICA model was used with field data to estimate the radiological dose to birds from exposure to {sup 137}Cs and {sup 241}Am with results between 1.26 to 3.83 {mu}Gy h{sup -1}, below the ERICA screening level of 10 {mu}Gy h{sup -1} and within the IAEA 40 {mu}Gy h{sup -1} guideline value below which potential adverse impacts on biota are unlikely. The study showed no link between bird population decline and anthropogenic discharges to the SPAs.

    Full Text Available In comparison to other sectors of the marine system, the palaeoceanography of the subarctic North Pacific Ocean is poorly constrained. New diatom isotope records of δ13C, δ18O, δ30Si (δ13Cdiatom, δ18Odiatom, and δ30Sidiatom are presented alongside existing geochemical and isotope records to document changes in photic zone conditions, including nutrient supply and the efficiency of the soft-tissue biological pump, between Marine Isotope Stage (MIS 4 and MIS 5e. Peaks in opal productivity in MIS 5b/c and MIS 5e are both associated with the breakdown of the regional halocline stratification and increased nutrient supply to the photic zone. Whereas the MIS 5e peak is associated with low rates of nutrient utilisation, the MIS 5b/c peak is associated with significantly higher rates of nutrient utilisation. Both peaks, together with other smaller increases in productivity in MIS 4 and 5a, culminate with a significant increase in freshwater input which strengthens/re-establishes the halocline and limits further upwelling of sub-surface waters to the photic zone. Whilst δ30Sidiatom and previously published records of diatom δ15N (δ15Ndiatom (Brunelle et al., 2007, 2010 show similar trends until the latter half of MIS 5a, the records become anti-correlated after this juncture and into MIS 4, suggesting a possible change in photic zone state such as may occur with a shift to iron or silicon limitation.

    Full Text Available Neosporosis is a disease that mainly affects cattle in both dairy and beef herds. The main definitive host of this parasite is the dog. Since 1984 and its first description a large number of data were published worldwide on this parasite. In Romania, the research regarding this parasite is limited. The purpose of this study was to determine the seroprevalence of Neospora caninum infection in dairy cattle from six regions in north-western Romania and to evaluate the intensity of infection in different animals groups. A total number of 901 samples (862 sera from adult cows and 39 sera from calves were collected from dairy farms and were screened for the presence of specific IgG anti-bodies using an enzyme-linked immunosorbent assay (ELISA. The overall seroprevalence for neosporosis was 34.6%. In adult cows and calves seroprevalences reached 34.8% (300/862 and 30.8% for calves (12/39 respectively. In cattle which had previously aborted, seroprevalence was 40.9%. These results indicate that N. caninum infection is widespread among animals reared in dairy systems from Romania and a program for farmer training and a strategy for reducing the economic impact of the disease are needed.

    Full Text Available Two major hospitals in Kano, North West Nigeria have recorded increasing resistance of clinical pathogens to broad spectrum β lactams, mediated by extended spectrum β- lactamase (ESβL and non ESBLs. A study was therefore undertaken to determine the occurrence and prevalence of plasmid and chromosomal mediated AmpC βL and carbapenemase in addition to already known ESBL due to increasing resistance of pathogens from the two hospitals to carbapenems, cephamycins and flouroquinolones. Antibiogram tests and ESBL, AmpC and carbapenemase production tests were performed on all the isolates. AmpC and carbapenemase producers were further screened for AmpC inducibility and metallo beta lactamase production respectively. Majority of the isolates (> 80% were resistant to both β-lactam and non β-lactam antibiotics. Reduced susceptibility to levofloxacin, nitrofurantoin, nalidixic acid and ofloxacin among the isolates were observed with the exception of P. aeruginosa which is totally resistant to imipenem and levofloxacin. An overall prevalence of 14.4%, 11.9% and 11.9.3% for ESβL, AmpC and carbapenemase was observed respectively. About 7.9% of the AmpC producers can over expressed the chromosomally mediated AmpC and 85.8% of the carbapenemase producers require metal for their action. Co-production of either of two and/or all of the enzymes was observed in E. coli, P. mirabilis and P. aeruginosa. Antibiotic resistance among isolates from the two hospitals is increasing and the major cause of this resistance in the pathogens studied are production of AmpC, carbapenemase (especially Metallo β- lactamase in addition to already known ESBL enzymes by the pathogens. Some of the isolates also possess the capacity to elaborate two or more of the enzymes concurrently, which would renders them resistant to a multitude of antibiotics.

    Full Text Available Background and Objectives: According to the available evidence, consumption of milk and other dairy products among Iranians is far less than recommendations. The share of different milks (i.e., traditionally vs. industrially processed and its associated variables are, however, neither consistent nor fully known in different Provinces.Materials and Methods: This cross-sectional study was conducted to determine household milk consumption and its association with selected socio-demographic factors in West Azarbayejan Province, North-west Iran. A total of 650 households were selected from urban and rural areas in three major Azeri and Kurdish districts (i.e. Urmia, Khoy and Mahabad using a multi-stage cluster sampling method. Data were collected using socio-economic and milk frequency questionnaires. Results: The findings indicated that traditionally-processed milk (bulk was the most common milk consumed at household level (62.5%. Mean of bulk milk consumption in urban and rural areas was 479±23 and 730±64 ml/wk per capita, respectively. It was also shown that establishment of the new food subsidization policy has decreased the mean of household milk consumption by approximately 3 l/wk in urban areas. Factor analysis detected a significant decrease in the higher tertiles of family size/ethnicity score consumption of both bulk and pasteurized milk, which resulted in decreased consumption of total milk. Conclusions: Designing and implementation of alternative approaches, such as targeted milk subsidies for poor households or vulnerable age-groups should be considered.

    The Nanyili (南一里), Laohegou (老河沟), and Shaiziyan (筛子岩) granitic intrusions are located in the southern margin of the Bikou (碧口) block in Pingwu (平武) area, Northwest Sichuan (四川). The petrography and geochemical characteristics of the granitic intrusions as well as their source and tectonic settings are reported and discussed in this article. The Laohegou and Shaiziyan granites are with high SiO2 (69.89 wt.%-73.05 wt.%) and Al2O3 contents, and A/CNK=1.04-1.12. They are typi-cal strongly peraluminous granites, with supersaturation in Al and Si. The abundance of ∑REE varies in the range of (33.13-89.12)×106. The rocks show an LREE enrichment pattern and obvious Eu nega-tive anomaly. The trace element geochemistry is characterized evidently by a negative anomaly of Ta, Nb, Ti, etc. and a positive anomaly of Rb, Ba, Sr, etc.. Zircons of the Nanyili granite have higher Th/U ratios, and their CL images have internal oscillatory zoning, suggesting that the zircons of the samples are igneous in origin. The LA ICP-MS zircon U-Pb isotopic concordia diagram yields an age of 223.1±2.6 Ma (MSWD=1.4), which indicates that the granodiorite intrusions formed in the early Late Triassic. The Nanyili, Laohegou, and Shaiziyan granites have the characteristics of post-eollisional granites and are regarded as post-orogenic granites. Thus, the granite intrusions are interpreted as syn-collisional granites that resulted from the crustal thickening caused by the collisions between the North China plate and the Yangtze plate during the Indosinian. The granitic intrusions formed in a transitional environment from syn- (compres-slonal environment) to post-collision (extensionalenvironment).

    Correlation between albedo and dry land surface temperature can serve as an indicator of processes, which control the temperature. The term dry land is used in reference to arid, semi-arid and dry subhumid regions, whose humidification coefficient ranges between 0.05 and 0.65 according to United Nations Convention to combat desertification in those countries experiencing serious drought and desertification, particularly in Africa. Geneva, 1994. The three main competing factors of underlying surface temperature control are an inherent feature of dry lands: first - radiation, second - evapotranspiration, third - aerodynamic control. This study is focused on seasonal cycle of parameters, which control surface temperature in the Sonora desert (North-West Mexico). The understanding of this process is important for monitoring of desertification. This is so because in a certain year, the time span of the period, during which the radiation factor is predominant, is an important factor in the desertification process. One indirect characteristic of prevalence of the radiation factor is Normalized Difference Vegetation Index (NDVI), which is an indicator of green phytomass. The main features of the ratio between albedo and surface temperature are discussed in terms of analysis of monthly means (albedo, temperature, NDVI) in the state of Sonora (29-32N, 111-115W), in particular, within the box 30-31N, 112-113W. The analysis of synchronous time series of albedo, surface temperature and NDVI has shown that the dominating temperature-controlling factors can switch within the year in the study area. The radiation factor is dominant in dry months (April - May) and the surface temperature is negatively correlated with albedo. This can cause generation of positive albedo-precipitation feedback, which in turn contributes to the desertification process.

    Full Text Available Abstract Background During the summer of 2006, a wave of wildfires struck Galicia (north-west Spain, giving rise to a disaster situation in which a great deal of the territory was destroyed. Unlike other occasions, the wildfires in this case also threatened farms, houses and even human lives, with the result that the perception of disaster and helplessness was the most acute experienced in recent years. This study sought to analyse the respiratory and mental health effects of the August-2006 fires, using consumption of anxiolytics-hypnotics and drugs for obstructive airway diseases as indicators. Methods We conducted an analytical, ecological geographical- and temporal-cluster study, using municipality-month as the study unit. The independent variable was exposure to wildfires in August 2006, with municipalities thus being classified into the following three categories: no exposure; medium exposure; and high exposure. Dependent variables were: (1 anxiolytics-hypnotics; and (2 drugs for obstructive airway diseases consumption. These variables were calculated for the two 12-month periods before and after August 2006. Additive models for time series were used for statistical analysis purposes. Results The results revealed a higher consumption of drugs for obstructive airway diseases among pensioners during the months following the wildfires, in municipalities affected versus those unaffected by fire. In terms of consumption of anxiolytics-hypnotics, the results showed a significant increase among men among men overall -pensioners and non-pensioners- in fire-affected municipalities. Conclusions Our study indicates that wildfires have a significant effect on population health. The coherence of these results suggests that drug utilisation research is a useful tool for studying morbidity associated with environmental incidents.

    Full Text Available To gain a better understanding of North American population history, complete mitochondrial genomes (mitogenomes were generated from four ancient and three living individuals of the northern Northwest Coast of North America, specifically the north coast of British Columbia, Canada, current home to the indigenous Tsimshian, Haida, and Nisga'a. The mitogenomes of all individuals were previously unknown and assigned to new sub-haplogroup designations D4h3a7, A2ag and A2ah. The analysis of mitogenomes allows for more detailed analyses of presumed ancestor-descendant relationships than sequencing only the HVSI region of the mitochondrial genome, a more traditional approach in local population studies. The results of this study provide contrasting examples of the evolution of Native American mitogenomes. Those belonging to sub-haplogroups A2ag and A2ah exhibit temporal continuity in this region for 5000 years up until the present day. Of possible associative significance is that archaeologically identified house structures in this region maintain similar characteristics for this same period of time, demonstrating cultural continuity in residence patterns. The individual dated to 6000 years before present (BP exhibited a mitogenome belonging to sub-haplogroup D4h3a. This sub-haplogroup was earlier identified in the same general area at 10300 years BP on Prince of Wales Island, Alaska, and may have gone extinct, as it has not been observed in any living individuals of the Northwest Coast. The presented case studies demonstrate the different evolutionary paths of mitogenomes over time on the Northwest Coast.

    Full Text Available Human serum paraoxonase-1 (PON1 prevents oxidation of low density lipoprotein cholesterol (LDL-C and hydrolyzes the oxidized form, therefore preventing the development of atherosclerosis. The polymorphisms of PON1 gene are known to affect the PON1 activity and thereby coronary artery disease (CAD risk. As studies are lacking in North-West Indian Punjabi's, a distinct ethnic group with high incidence of CAD, we determined PON1 activity, genotypes and haplotypes in this population and correlated them with the risk of CAD.350 angiographically proven (≥ 70% stenosis CAD patients and 300 healthy controls were investigated. PON1 activity was determined towards paraoxon (Paraoxonase; PONase and phenylacetate (Arylesterase; AREase substrates. In addition, genotyping was carried out by using multiplex PCR, allele specific oligonucleotide -PCR and PCR-RFLP methods and haplotyping was determined by PHASE software. The serum PONase and AREase activities were significantly lower in CAD patients as compared to the controls. All studied polymorphisms except L55M had significant effect on PONase activity. However AREase activity was not affected by them. In a logistic regression model, after adjustment for the conventional risk factors for CAD, QR (OR: 2.73 (1.57-4.72 and RR (OR, 16.24 (6.41-41.14 genotypes of Q192R polymorphism and GG (OR: 2.07 (1.02-4.21 genotype of -162A/G polymorphism had significantly higher CAD risk. Haplotypes L-T-G-Q-C (OR: 3.25 (1.72-6.16 and L-T-G-R-G (OR: 2.82 (1.01-7.80 were also significantly associated with CAD.In conclusion this study shows that CAD patients had lower PONase and AREase activities as compared to the controls. The coding Q192R polymorphism, promoter -162A/G polymorphism and L-T-G-Q-C and L-T-G-R-G haplotypes are all independently associated with CAD.

    Runoff and soil erosion induce major environmental and economic damages. Concentrated runoff control by aboveground plant biomass in upstream areas constitutes a key feature to reduce runoff and soil erosion in Western Europe (WE). Indeed, aboveground plant biomass can reduce runoff and soil erosion respectively by increasing hydraulic roughness and trapping sediments. However, studies of plant effect on runoff reduction are usually based on the taxonomical characterisation of species and do not refer to effect of aboveground plant functional traits. Plant functional traits approach allows to understand ecosystem processes and quantify services. Traits effect could vary depending on hydrological processes (i.e., discharge) and their aggregation could have a synergetic effect on hydraulic roughness and erosion reduction. In this study, objectives are to i) examine effects of aboveground plant functional traits of herbaceous hedges on hydraulic roughness; ii) test the effects of their aggregation on hydraulic roughness. Seven aboveground functional traits were measured on 14 indigenous plant species from North-West Europe with a high morphological variability (stem and leaf densities; stem diameter, stiffness and dry matter content; leaf area and specific leaf area (SLA)). Those species are perennial herbaceous caespitose or comprising dry biomass in winter. Effects of plant functional traits and their abundance within the community on hydraulic roughness were examined using a runoff simulator at four discharges. Furthermore, the effect of plant functional diversity was analysed using four monospecific (mono-trait) conditions compared to multispecific (multi-traits) conditions. Results showed traits and their abundance influence hydraulic roughness. Indeed, leaf density and leaf area (traits), as well as plant community weighted stem, leaf and shoot areas, stem diameter and SLA are significantly correlated to hydraulic roughness. Moreover, leaf density and leaf area

    Lead concentrations in tree rings of sycamore (Acer pseudoplatanus L.), oak (Quercus robur L.) and Scots pine (Pinus sylvestris L.) sampled at a parkland in north-west England were measured in wood formed since the mid-1800s. Concentrations of Pb in Scots pine and oak peaked in wood formed between 1900 and 1940, most likely because of Pb accumulation in heartwood, indicating that oak and Scots pine are unsuitable for monitoring temporal changes in Pb deposition at the study site. In contrast, Pb concentrations in sycamore, a species that has similar heartwood and sapwood chemistry, were relatively constant in wood formed between the mid-1800s and 1950. Lead concentrations decreased steadily in sycamore tree rings formed after the 1950s, and decreased more abruptly in wood formed after 1985. This sharp decrease in wood Pb cannot be due to decreases in soil Pb concentration. Stable Pb isotope analysis was used to further investigate Pb patterns in sycamore wood. Excess 206Pb/207Pb ratios in tree-rings of sycamore were relatively constant, approximately 1.17, in wood formed prior to the 1930s, but decreased steadily thereafter reaching a minimum value of approximately 1.16 in wood formed between 1975 and 1985 after which time 206Pb/207Pb ratios increased. This pattern is consistent with changes in Pb isotope ratios measured in peat, sediment and aerosol samples in the UK. However, the magnitude of the decrease in 206Pb/207Pb (largely due to gasoline Pb) is considerably lower than in other studies and our estimates indicate that less than 20% of the total Pb in sycamore wood measured since the mid-1800s is derived from gasoline emissions. A more likely explanation for the pattern of Pb observed in sycamore tree rings is that soil Pb accumulates within rings of the diffuse porous wood over a number of years. Such uptake patterns would result in lower Pb concentrations in the outer (more recently formed) tree rings, which coincide with recent reductions in Pb deposition

  11. Evidence for UHP metamor phism of eclogites from the Altun Mountains

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Ultrahigh pressure (UHP) metamorphism refers to metamorphism that has occurred at pressures for the stability of coesite. The polycrystalline quartz inclusions showing the characteristic texture within garnets of eclogites indicates the pre-existence of coesites under the peak metamorphic condition. The unusual exsolution textures in ompacites and apatites, and the pressure estimations of phengite-bearing eciogites have been taken to provide further proof of eclogite formation under the UHP conditions.Combined with the fact that coesites have been observed in country rocks of eclogites in North Qaidam Mountains, another UHP metamorphic belt cut by the large-scale strikeslip fault in the AItun-North Qaidam area of China is confirmed.``

    The paraoxonase (PON1) gene polymorphisms are known to affect the PON1 activity and coronary artery disease (CAD) risk. Studies done so far have given conflicting results. In the present study, we determined the role of PON1 genetic variants and PON1 activity in the development of CAD in North-West Indian Punjabis, a distinct ethnic group, having high incidence of both CAD and type 2 diabetes. 300 angiographically proven CAD with type 2 diabetics and 250 type 2 diabetics with no clinically evident CAD were enrolled. Serum PON1 activity and genotyping of coding (Q192R, L55M) and promoter (-909G/C, -162A/G, -108C/T) region polymorphisms were carried out and haplotypes were determined using PHASE software. The serum PON1 activity was significantly lower in CAD with type 2 diabetics as compared to diabetics alone (51.0 vs. 114.2nmol/min/ml). In logistic regression model after adjusting for confounding variables, lower PON1 activity was found to be significantly associated with CAD risk in type 2 diabetics with OR being 16.8 (95% CI: 10.2-27.7). The lower serum PON1 activity, irrespective of genotypes and haplotypes is a risk factor for development of CAD in North-West Indian Punjabis with type 2 diabetics.

    The pollution caused by plastic debris is an environmental problem with increasing concern in the oceans. Among the plastic polymers, polystyrene (PS) is one of the most problematic plastics due to the direct public health risk associated with their dispersion, as well as the numerous adverse environmental impacts which arise both directly from the plastics and from their degradation products. Little is known about their potential distribution characteristics throughout the oceans. For the first time, we report here on the regional distribution of styrene monomer (SM), styrene dimers (SD; 2,4-diphenyl-1-butene, SD1; 1,3-diphenyl propane, SD2), and styrene trimer (2,4,6-triphenyl-1-hexene: ST1), as products of PS decomposition determined from samples of sand and seawater from the shorelines of the North-West Pacific ocean. In order to quantitatively determine SM, SD (=SD1+SD2), and ST1, a new analytical method was developed. The detection limit was 3.3 μg L(-1), based on a signal-to-noise ratio of three, which was well-suited to quantify levels of SM, SD, and ST1 in samples. Surprisingly, the concentrations of SM, SD, and ST1 in sand samples from the shorelines were consistently greater than those in seawater samples from the same location. The results of this study suggest that SM, SD, and ST1 can be widely dispersed throughout the North-West Pacific oceans.

    Full Text Available A number of researchers are studying regional specifications of Russia from a variety of different perspectives. Economic geography has developed its own methods of approaching the study of territories, and looks, in particular, at geographical distribution of labour. In this article, we use the framework provided by this discipline to describe the changes in the economy of the Russian North-West in the first decade of the 21st century. We combine publicly available data to propose new methods of evaluation of regional economic efficiency. We also identify and describe new trends of North-West development that have not yet been reflected upon by the researchers in the field. We conclude that, having overcome the crisis of the 1990s, the economy of the Russian North-West displays an overall positive trend of coming back to the territorial structures of the beginning of the 20th century.

    BACKGROUND: The emergence of democracy in South Africa led to a need to transform all public structures, including the health care system. The aim has been to transform these structures in order to bring them in line with the new culture of human rights. Transformation of the whole health care system is motivated by a number of key objectives, which include achieving equity in resource allocation and health service delivery, developing primary health care infrastructure and decentralising services to promote community participation. AIMS OF THE STUDY: In the context of de-institutionalising mental health services in South Africa, this study aimed to investigate community mental health service needs of mental health service users and that of their families in the Moretele district, North-West province, South Africa. METHODS: The study was conducted in three clinics situated in three different communities in the Moretele district. Data collection consisted of : 147 clinical record reviews, 105 interviews with patients followed by a joint interview with a family member, 83 interviews with caregivers and eight interviews with community key informants (traditional healers, a civic leader, a councillor, a retired teacher, and a physician). RESULTS: The majority of service users were males (54%). The mean age was 41 years and 63% had completed primary schooling.Patients were recorded as having only one of two primary diagnoses, namely schizophrenia (57%) or epilepsy (41%). However, a review of prescribed drugs and caregiver interviews showed that there was a presence of mood disorders among service users. The local hospital was service users primary entry point into the mental health care system, followed by traditional healers (30%). Interviews with service users, service providers and caregivers reveal limited knowledge of patient illness. Nevertheless, service users who had epilepsy were more likely to provide details of their illness than those with mental illness

    This study examined the population structure, reproductive cycle and feeding pattern of the lanternfish Lampanyctus crocodilus in the Balearic Basin (north-west Mediterranean Sea) from a depth of 450 to 1800 m and at a seasonal scale. Juveniles were mainly located at shallower depths, but also at deepest stations in autumn, while adults mostly inhabited intermediate depths with their centre of population density (CPD) located at 800-1000 m of depth. The migration of adults to deeper depths was detected in late summer to autumn, probably linked to the occurrence of nepheloid layers at c. 1200 m, which in turn enhances the biomass of the zooplankton prey. The diet was mainly based on euphausiids and mysids, with marked seasonal variations both on the upper (450-800 m) and lower (1000-1800 m), where suprabenthic gammariids and pelagic decapods were also dominant. Stomach fullness increased from winter to autumn on the US, while it had a maximum in spring on the LS, in parallel with high consumption of gelatinous zooplankton, which is probably more available after the phytoplankton bloom in late winter. Reproduction occurred in winter, confirmed by the higher percentage of mature females and high gonadosomatic indices (I(G)) at both depth ranges. Hepatosomatic indices (I(H)) showed an inverse trend to I(G) on the US, except in autumn, and was almost parallel on the LS, probably attributable to the migration of adults, which determined different temporal schemes in energy use and storage for reproduction on the US v. LS. Consistent with the different patterns observed at the two depth ranges, environmental drivers of fullness (i.e. feeding intensity) and I(G) (as a proxy of reproductive cycle) differed on the US and LS. The biomass of mysids and euphausiids was the greatest explanatory variables of fullness on the US and LS, pointing to the increasing feeding intensity when a resource was more available. I(H) also explained fullness, suggesting that greater

    Full Text Available The paper presents cultural heritage, cultural tourism potential of North-West Region of Romania face to face with restoration and sustainable valorization of cultural heritage as a major domain of intervention of regional policy in Romania. Due to Romanian regionalization form, the Regional Operational Programme (ROP is currently the only programme of regional policy in Romania in 2007-2013. One of the major domains of intervention of ROP 2007-2013 in Romania was restoration and sustainable valorization of cultural heritage. The first paper specific objective is to explore projects contracted until 31.12.2013 in the field of restoration and sustainable valorization of cultural heritage in North-West Region of Romania and their regional development relevance in the context of existing regional development strategies. The second paper specific objective is to present a model of restoration of cultural heritage in a sustainable way throughout the case study of Revitalization of the Oradea Fortress in order to introduce it in the tourism circuit - that could become an example for other cultural sites around the region and a succes story in the field of cultural tourism based of ROP 2007-2013 experience. Exploring rich cultural heritage of the North-West Region face to face with poor condition of cultural heritage sites and investments required in order to introduce them in touristic circuit, the paper concludes that all contracted projects are relevant for sustainable valorization of regional cultural heritage and cultural tourism potential in the context of existing regional development strategies, but they contributed only partially to regional specific needs. Also, the paper concludes that number of ROP 2007-2013 projects implemented in the field of cultural heritage is surprisingly small, area of interest of these projects is rather narrow and analyzes the most important causes for these gaps. Based on the case study presented, the paper

    The North Boquerón Bay–Punta Montalva fault zone has been mapped crossing the Lajas Valley in southwest Puerto Rico. Identification of the fault was based upon detailed analysis of geophysical data, satellite images, and field mapping. The fault zone consists of a series of Cretaceous bedrock faults that reactivated and deformed Miocene limestone and Quaternary alluvial fan sediments. The fault zone is seismically active (local magnitude greater than 5.0) with numerous locally felt earthquakes. Focal mechanism solutions suggest strain partitioning with predominantly east–west left-lateral displacements with small normal faults striking mostly toward the northeast. Northeast-trending fractures and normal faults can be found in intermittent streams that cut through the Quaternary alluvial fan deposits along the southern margin of the Lajas Valley, an east–west-trending 30-km-long fault-controlled depression. Areas of preferred erosion within the alluvial fan trend toward the west-northwest parallel to the onland projection of the North Boquerón Bay fault. The North Boquerón Bay fault aligns with the Punta Montalva fault southeast of the Lajas Valley. Both faults show strong southward tilting of Miocene strata. On the western end, the Northern Boquerón Bay fault is covered with flat-lying Holocene sediments, whereas at the southern end the Punta Montalva fault shows left-lateral displacement of stream drainage on the order of a few hundred meters.

    Full Text Available Abstract Background Ethiopia is one of the most densely populated countries in Africa with an estimated population of 77.1 million in mid-2007. Uncontrolled fertility has adversely influenced the socio-economic, demographic and environmental situations of the country. It is one of the largest and poorest countries that, even in the midst of crisis, has maintained high levels of fertility. This study was aimed at investigating the most important factors influencing fertility behavior in Northwest Ethiopia. Methods A comparative cross-sectional study which included 2424 women aged 25 years and above was undertaken in the Amhara region of Northwest Ethiopia. The study subjects were grouped into high fertile and low fertile categories. There were 1011 and 1413 women in the high and low fertile groups, respectively. A multi-stage cluster sampling stratified by place of residence was employed to select the required study subjects. Both bivariate and multivariate logistic regression techniques were used to analyze the data. Results Among the 25 variables considered in this study, only 9 of them were found significantly and independently associated with the level of fertility. Women with at least secondary education were at a lower risk of high fertility with OR = 0.37 (95% CI: 0.21 to 0.64 compared to those with no formal education. However, women with primary education did not show any significant difference when compared with the same baseline group. Age at first marriage was inversely associated with the number of children ever born alive. Place of residence, household expenditure, number of children who have died, attitude towards using contraceptives, women's knowledge on the safe period, and current marital status were the other variables that showed significant associations with the level of fertility. Conclusion Female education beyond the primary level, reduced infant and child mortality, delayed marriage and correct knowledge on the safe

    Combined records of snow accumulation rate, δ18O and deuterium excess were produced from several shallow ice cores and snow pits at NEEM (north-west Greenland), covering the period from 1724 to 2007. They are used to investigate recent climate variability and characterize the isotope-temperature relationship. We find that NEEM records are only weakly affected by inter-annual changes in the North Atlantic Oscillation. Decadal δ18O and accumulation variability is related to North Atlantic SST, and enhanced at the beginning of the 19th century. No long-term trend is observed in the accumulation record. By contrast, NEEM δ18O shows multi-decadal increasing trends in the late 19th century and since the 1980s. The strongest annual positive δ18O anomaly values are recorded at NEEM in 1928 and 2010, while maximum accumulation occurs in 1933. The last decade is the most enriched in δ18O (warmest), while the 11-year periods with the strongest depletion (coldest) are depicted at NEEM in 1815-1825 and 1836-1846, which are also the driest 11-year periods. The NEEM accumulation and δ18O records are strongly correlated with outputs from atmospheric models, nudged to atmospheric reanalyses. Best performance is observed for ERA reanalyses. Gridded temperature reconstructions, instrumental data and model outputs at NEEM are used to estimate the multi-decadal accumulation-temperature and δ18O-temperature relationships for the strong warming period in 1979-2007. The accumulation sensitivity to temperature is estimated at 11 ± 2% °C-1 and the δ18O-temperature slope at 1.1 ± 0.2‰ °C-1, about twice larger than previously used to estimate last interglacial temperature change from the bottom part of the NEEM deep ice core.

    Dopamine D2 receptor (DRD2) is one of the essential neurotransmitters in the brain studied extensively in the field of psychiatric disorders, alcoholic behaviors and Pharmacology. It is also a promising gene for studying the evolutionary and genetic variation among populations. The present study was an attempt to understand the extent of genetic variation among five different ethnic groups (Bania, Brahmin, Jat Sikh, Khatri and Scheduled caste) of Punjab (North West India). A total of 1012 individuals belonging to the above mentioned groups were analyzed for three TaqI Polymorphic loci of DRD2 and ankyrin repeat and kinase domain containing 1 (ANKKI) using the allele frequencies and haplotype frequency distribution pattern. All the three loci were found to be polymorphic among the studied populations. The average heterozygosity for all loci in these ethnic groups was fairly substantial ranging from 0.3936 to 0.4986. The genetic differentiation among the population was observed to be in order of 0.0053.Among of the eight studied haplotypes, only six were shared by all the ethnic groups. TaqID and TaqIB loci were reported to be in significantly higher linkage disequilibrium (LD) in Scheduled Caste only, whereas TaqIA and TaqID showed modest LD in Brahmin, Jat Sikh and Khatri. Multidimensional scaling analysis revealed that the studied ethnic groups formed a close cluster, suggesting similar genetic structure of these populations which are in close proximity with other Indo European speaking North Indian and western Indian population groups. Overall this study highlights the genomic uniformity among the ethnic groups of Punjab (North-West India) owing to their common ancestral history and geographical closeness.

    Depositional models of ancient lakes in thin-skinned retroarc foreland basins rarely benefit from appropriate Quaternary analogues. To address this, we present new stratigraphic, sedimentological and geochemical analyses of four radiocarbon-dated sediment cores from the Pozuelos Basin (PB; northwest Argentina) that capture the evolution of this low-accommodation Puna basin over the past ca. 43 cal kyr. Strata from the PB are interpreted as accumulations of a highly variable, underfilled lake system represented by lake-plain/littoral, profundal, palustrine, saline lake and playa facies associations. The vertical stacking of facies is asymmetric, with transgressive and thin organic-rich highstand deposits underlying thicker, organic-poor regressive deposits. The major controls on depositional architecture and basin palaeogeography are tectonics and climate. Accommodation space was derived from piggyback basin-forming flexural subsidence and Miocene-Quaternary normal faulting associated with incorporation of the basin into the Andean hinterland. Sediment and water supply was modulated by variability in the South American summer monsoon, and perennial lake deposits correlate in time with several well-known late Pleistocene wet periods on the Altiplano/Puna plateau. Our results shed new light on lake expansion–contraction dynamics in the PB in particular and provide a deeper understanding of Puna basin lakes in general.

    Knowledge of mastitis pathogens and their predominance as well as understanding of risk factors are prerequisites to improve udder health in a herd, region or country. In Ethiopia, such information is scarce, despite the fact that mastitis is an important cattle disease in the country. A cross-sectional study that describes prevalence and causative agents of subclinical mastitis (SCM) as well as risk factors at cow and herd level was conducted on 167 dairy farms in North-West Ethiopia. On average, 33% of the quarters and 62% of the cows were California Mastitis Test (CMT) positive, but the within herd quarter level prevalence ranged between 0 and 100%. A total of 1543 milk samples, being 27 quarters that showed signs of CM, 606 CMT positive quarters and 910 CMT negative quarters were cultured, respectively 40%, 67% and 47% was positive on bacteriological culture. Coagulase negative staphylococci (CNS) (31%) followed by Staphylococcus aureus (9%) were the pathogens most frequently isolated. Based on face-to-face questionnaire data, 35 herd level and 13 cow level factors were evaluated for their association with SCM (based on CMT) and with a positive culture for any bacteria, CNS or S. aureus. Cows with a history of CM, of higher parity, >150days in milk (DIM) and herds with owners that have >10th grade level of education had higher odds of SCM. The odds of being culture positive for any bacteria was higher in cows with ≥25% Holstein Friesian blood level (HBL), >150 DIM, housed on cemented floors, and milked by squeezing rather than stripping. Similarly, the odds of culturing CNS was higher in cows with 25-50% HBL, >150 DIM, and milked by squeezing. Staphylococcus aureus was more often found in cows with a history of CM and in larger herds. Checking the udder for mastitis, feeding cows according to their requirements and allowing calves to suckle the cows were negatively associated with SCM, with culturing any bacteria and with culturing CNS, respectively.

The average mass concentrations of particulates (PM10; PM2.5; PM1 were found to be 118±36, 34±11, and 19±10 µgm−3 and 140±48, 30±13, and 14±06 µgm−3 over Dehradun and Patiala, respectively. The average aerosol optical depth (AOD500 nm is observed to be 0.62±0.11 over Dehradun and 0.56±0.21 over Patiala. Ångström exponent and fine mode fraction show higher values over Dehradun as compared to Patiala. The average mass concentration of black carbon was found to be 3343±546 ngm−3 and 6335±760 ngm−3 over Dehradun and Patiala, respectively. The diurnal pattern of BC is mainly controlled by boundary layer dynamics and local anthropogenic activities over both the stations. The average single scattering albedo (SSA500 nm exhibited low value over Patiala (0.83±0.01 in comparison to Dehradun (0.90±0.01, suggesting the abundance of absorbing type aerosols over Patiala. The average atmospheric aerosol radiative forcing is +37.34 Wm−2 and +54.81 Wm−2 over Dehradun and Patiala, respectively, leading to atmospheric heating rate of 1.0 K day−1 over Dehradun and 1.5 K day−1 over Patiala.

    Climate variability in the North Atlantic has been linked in part to the North Atlantic Oscillation (NAO). The NAO influences marine ecosystems in the northwestern Atlantic and transport variability of the cold Labrador Current. Understanding historic patterns of NAO variability requires long-term and high-resolution climate records that are not available from instrumental data. Here we present the first century-scale proxy record of sea surface temperature (SST) variability from the Newfoundland shelf, a region from which other annual-resolution shallow marine proxies are unavailable. The 116 year record was obtained from three sites along the eastern Newfoundland shelf using laser ablation inductively coupled mass spectrometry-determined Mg/Ca ratios in the crustose coralline alga Clathromorphum compactum. The alga is characterized by a high Mg-calcite skeleton exhibiting annual growth increments and a century-scale lifespan. Results indicate positive correlations between interannual variations in Mg/Ca ratios and both station-based and gridded instrumental SST. In addition, the record shows high spatial correlations to SST across the Newfoundland shelf and the Gulf of St. Lawrence. Before 1950 the Mg/Ca proxy record reveals significant departures from gridded temperature records. While the Newfoundland shelf is generally considered a region of negative correlations to the NAO, the algal time series as well as a recent modeling study suggest a variable negative relationship with the NAO which is strongest after ˜1960 and before the mid-1930s.

    Aerosol radiative forcing is an important parameter in the Earth's radiation budget and can be an important driver of atmospheric circulation and the hydrological cycle. Accurate estimation of aerosol radiative forcing requires measurement of both the extensive and intensive optical properties of aerosols. While the intensive optical properties are independent of aerosol mass or number, they are critical inputs when calculating radiative forcing with applications to climate research, satellite remote sensing and model validations. The key aerosol intensive properties that need to be evaluated include single scattering albedo (SSA), the angstrom exponent, the asymmetry parameter, the radiative forcing efficiency, and the hygroscopic scattering factor. We report here on values of these variables over the Cape Cod and nearby northwest Atlantic Ocean during the Two Column Aerosol Project (TCAP). The average SSA shows a distinct profile having higher SSA values below the top of well-mixed residual layer (RL) and lower SSA above it. Aerosol in the free troposphere (FT) were found to have less spectral dependence in their optical properties, lower back scatter fraction and higher hygroscopic growth relative to aerosols found in the RL. Analysis of individual particle composition suggests that that ratio of aged to fresh aerosol numbers in the FT is 70% higher compared to aerosols measured in the RL, and that smoke from biomass burning contributed ~10% to this number. Single particle analysis also reveals that the fraction and variability of coated black carbon (BC) aerosol is higher in the FT relative to that measured in the residual layer. The daily radiative forcing efficiency of these aerosols in the FT is factor 2 higher than below RL. Seven years (2007-2013) of CALIPSO satellite observations show that the mean altitude of the top of smoke layers (~3.3 km) consistent with these in situ observations from TCAP. Overall, the long term CALIPSO observations characterizes

    The study described here is based on the measurements of soil gas radon–thoron concentrations performed at Dharamsala region of north-west (NW) Himalayas, India. The study area is tectonically and environmentally significant and shows the features of ductile shear zone due to the presence of distinct thrust planes. Solid state nuclear track detectors (LR-115 films) have been used for the soil gas radon–thoron monitoring. Twenty five radon–thoron discriminators with LR-115 films were installed in the borehole of about 50 cm in the study areas. The recorded radon concentration varies from 1593 to 13570 Bq/m3 with an average value of 5292 Bq/m3. The recorded thoron concentration varies from 223 to 2920 Bq/m3 with an average value of 901 Bq/m3. The anomalous value of radon–thoron has been observed near to the faults like main boundary thrust (MBT and MBT2) as well as neotectonic lineaments in the region.

    Full Text Available The shipbuilding industry clusters in the Eastern Baltic Sea region, i. e. Estonia, Finland and North-West Russia, may benefit significantly from increased mutual cooperation; however, the international networks between the clusters are still poorly developed. The aim of this article is to analyse the preconditions for cluster internationalization between these clusters, which are rather different but complementary in terms of skills. The research material for this desk study was collected from various sources, including journal articles, media, research reports, and other publications. The results of the study indicate that the increasing cooperation within the triangle of these clusters has a significant potential in terms of combining different areas of expertise and creating a multidimensional maritime industry hub in the region. However, differences in the cluster structure and development stages lead to certain difficulties in achieving these objectives. In conclusion, the authors identify the factors both facilitating and inhibiting networking between the three clusters. This study provides a platform for further research focusing on the factors identified and gives ideas for public discussion on increased inter-cluster cooperation.

    Full Text Available Background: There is a paucity of information on the actual costs incurred by the family as a result of musculoskeletal injuries due to road traffic crash from our part of India. This study was conducted with the objective to ascertain the costs of initial management of musculoskeletal injuries due to road traffic crashes. Materials and Methods: This prospective study was conducted as a register-based descriptive study in a tertiary care teaching hospital in a rural area (with a predominantly mountainous terrain of North-West India. All patients with nonfatal musculoskeletal injuries due to road traffic crashes, presenting between 2014 and 2015 and agreeing to participate in the study were included in the study. Results: Of 313 cases, 116 were managed conservatively, whereas in 189 cases, operative intervention was required. In 8 cases, both the modalities of management were required. The average cost of management was Rs. 20,386 in operative group. The average cost in the conservative group was Rs. 3726. Average cost calculated for patients in whom both modality of treatment was required was Rs. 24,000. It was observed that the indirect cost of management was proportionately higher in conservative group. Conclusions: The initial cost of management for patients managed conservatively is less than those managed by operative intervention. Importantly, however, the indirect cost of management is a major contributor to the total cost of management.

    Essential oils obtained from flowers, leaves and stems of Origanum vulgare L. ssp. viride (Boiss.) Hayek., growing wild in Ardabil Province (north-west Iran), were analyzed by GC and GC/MS. beta-Caryophyllene was the major constituent in all three oils (48.1%, 50.1% and 60.2%, respectively). Of the 19 components detected in the flower oil, comprising 96.3% of the total, the major components were 1,8-cineole (11.6%), alpha-pinene (6.9%), and gamma-cadinene (4.8%). 1-Octen-3-ol (23.8%), and 1,8-cineole (8.5%) predominated in the leafoil. In the stem oil, other main constituents were bicyclogermacrene (9.8%), 1,8-cineole (6.4%), borneol (5.1%), and pinocarvone (4.4%). The essential oils were evaluated for their antibacterial activity against 10 selected microorganisms. The data obtained contribute to the future use of certain essential oils as natural preservatives for food products, due to their safety and positive effect on shelf life.

    Short lived, low and medium level waste called {sup t}echnological waste produced by the La Hague Reprocessing Plant have been stored in the La Hague North-West concrete-lined pits until implementation at {sup *}ANDRA's Centre de Stockage della Manche (CSM). COGEMA decided to retrieve and condition 11,000 m{sup 3} of humid solid rad waste, stored in bulk in pits. On account of the variety of rad waste kinds, retrieving and conditioning operations represented real challenge. One goal of these operations was to ensure that the work was performed in complete safety towards environment with optimum containment and with the best radiation protection for the personnel involved. COGEMA decided to split the work into two phases. The feedback from the first phase was very helpful to the second phase. This report describes the experience gained from February 1990 to December 1998, taking into account rad waste and integrated dose rate results conditioning such waste. The procedures and means used and improved by COGEMA to comply with ANDRA's storage standards and the ever-decreasing financial costs generated by the workers, allowed to retrieve and condition 11,000 m{sup 3} of old solid rad waste with competitive costs and in complete safety and protection of the environment. {sup *}ANDRA: National Rad waste Management Agency.

    Full Text Available The shipbuilding industry clusters in the Eastern Baltic Sea region, i. e. Estonia, Finland and North-West Russia, may benefit significantly from increased mutual cooperation; however, the international networks between the clusters are still poorly developed. The aim of this article is to analyse the preconditions for cluster internationalization between these clusters, which are rather different but complementary in terms of skills. The research material for this desk study was collected from various sources, including journal articles, media, research reports, and other publications. The results of the study indicate that the increasing cooperation within the triangle of these clusters has a significant potential in terms of combining different areas of expertise and creating a multidimensional maritime industry hub in the region. However, differences in the cluster structure and development stages lead to certain difficulties in achieving these objectives. In conclusion, the authors identify the factors both facilitating and inhibiting networking between the three clusters. This study provides a platform for further research focusing on the factors identified and gives ideas for public discussion on increased inter-cluster cooperation.

    Full Text Available Values and character education possess the inherent building blocks for the preservation of a healthy society. Values and character education have the potential to address moral issues in society and especially in educational institutions, such as schools, colleges and universities. One of the primary aims of values and character education is to allow students to experience life to the fullest. Values and character education could probably ensure a better life and future for South Africa‟s youth.From the available literature, it is evident that society is experiencing a crisis regarding values, character and morality. The decline of human and societal values portrayed in the media has compelled the current government to initiate values education programmes in colleges and other institutions such as universities.In order to determine the values orientation among students of Further Education and Training Colleges (FET in the North-West Province, an empirical study was done to ascertain students‟ opinions and the contributions of values education and character education. Semi-structured interviews were also conducted with the student council, the head of support services, as well as an official of student support services.

    The relationship between the frequency of spring dust storms over Tarim Basin in northwest China and the winter North Atlantic Oscillation (NAO) is investigated by using the observed dust storm frequency (DSF) and the 10 m wind velocity at 36 stations in Tarim Basin and the National Centers for Environment Prediction/National Center for Atmospheric Research reanalysis data for the period 1961-2007. The spring DSF (winter NAO) index shows a clear decreasing (increasing) linear trend over 1961-2007. The winter NAO correlates well with the subsequent spring DSF over Tarim Basin on both interannual and interdecadal time scales and its interannual to interdecadal variation plays an important role in the spring DSF. Two possible physical mechanisms are identified. One is related to the large scale anomalous circulations in spring in the middle to high troposphere modulated by the winter NAO, providing the background of dynamical conditions for the dust storm occurrences. The other is related to the shifts in the local horizontal sea level pressure (SLP) gradients and 10 m wind speed, corresponding to changes in the large scale circulations in spring. The decrease in the local 10 m wind speed due to the reduced horizontal SLP gradients over Tarim Basin during the strong winter NAO years contributes to the decline of the DSF in the subsequent spring.

  4. Using Remotely-Sensed Land Cover and Distribution Modeling to Estimate Tree Species Migration in the Pacific Northwest Region of North America

    2016-01-01

    Full Text Available Understanding future tree species migration is challenging due to the unprecedented rate of climate change combined with the presence of human barriers that may limit or impede species movement. Projected changes in climatic conditions outpace migration rates, and more realistic rates of range expansion are needed to make sound environmental policies. In this paper, we develop a modeling approach that takes into account both the geographic changes in the area suitable for the growth and reproduction of tree species, as well as limits imposed geographically on their potential migration using remotely-sensed land cover information. To do so, we combined a physiologically-based decision tree model with a remotely-sensed-derived diffusion-dispersal model to identify the most likely direction of future migration for 15 native tree species in the Pacific Northwest Region of North America, as well as the degree that landscape fragmentation might limit movement. Although projected changes in climate through to 2080 are likely to create favorable environments for range expansion of the 15 tree species by 65% on average, by limiting the potential movement by previously published migration rates and landscape fragmentation, range expansion will likely be 50%–90% of the potential. The hybrid modeling approach using distribution modeling and remotely-sensed data fills a gap between naïve and more complex approaches to take into account major impediments on the potential migration of native tree species.

    Full Text Available European corn borer (Ostrinia nubilalis Hubner is one of the major corn pest in the world and in Croatia. Former investigations of corn borer in Croatia covered mostly its Eastern region. In trials conducted in 1998 and 1999 the research was extended to the North Western part of Croatia too. Macro trials were carried out with corn hybrids of FAO groups 200-600 at three localities: Križevci, Agricultural institute Osijek and at «Belje» PIK Karanac. In 1998 the intensity of the corn borer attack at the locality of «Belje» PIK Karanac was about 37.92% and in Agricultural institute Osijek 80.83%. In 1999 it varied between 37.08% at the locality of Agricultural Institute Osijek and 71.20% at the locality in Križevci. The estimated number of holes per plant in all three localities in both years was higher than the number of caterpillars. Length of damage per plant was between 0.38 and 18.80 cm. The data showed significant differences in the intensity of damaging effects on different localities while no significant differences concerning various hybrids were found. The statistical data concerning yield in both years showed significant differences among hybrids, localities and their interactions.

    Full Text Available Abstract Background Incentive or reward schemes are becoming increasingly popular to motivate healthy lifestyle behaviours. In this paper, insights from a qualitative and descriptive study to investigate the uptake, impact and meanings of a breastfeeding incentive intervention integrated into an existing peer support programme (Star Buddies are reported. The Star Buddies service employs breastfeeding peer supporters to support women across the ante-natal, intra-partum and post-partum period. Methods In a disadvantaged area of North West England, women initiating breastfeeding were recruited by peer supporters on the postnatal ward or soon after hospital discharge to participate in an 8 week incentive (gifts and vouchers and breastfeeding peer supporter intervention. In-depth interviews were conducted with 26 women participants who engaged with the incentive intervention, and a focus group was held with the 4 community peer supporters who delivered the intervention. Descriptive analysis of routinely collected data for peer supporter contacts and breastfeeding outcomes before and after the incentive intervention triangulated and retrospectively provided the context for the qualitative thematic analysis. Results A global theme emerged of 'incentives as connectors', with two sub-themes of 'facilitating connections' and 'facilitating relationships and wellbeing'. The incentives were linked to discussion themes and gift giving facilitated peer supporter access for proactive weekly home visits to support women. Regular face to face contacts enabled meaningful relationships and new connections within and between the women, families, peer supporters and care providers to be formed and sustained. Participants in the incentive scheme received more home visits and total contact time with peer supporters compared to women before the incentive intervention. Full participation levels and breastfeeding rates at 6-8 weeks were similar for women before and after

    Background The goal of reducing maternal mortality can be achieved when women receive important service components at the time of their maternity care. This study attempted to assess the availability and the components of maternity services according to the perspectives of service users and providers. Method A linked facility and population-based survey was conducted over three months (January to March 2012) in North Gondar Zone. Twelve kebeles (clusters) were selected randomly from six districts to identify maternity clients cared for by skilled providers. Then 12 health centers and 3 hospitals utilized by the corresponding cluster population were selected for facility survey. Interview with facility managers/heads, providers and clients and observations were used for data collection. Data were entered using Epi Info and were exported to SPSS software for analysis. Results Antenatal and delivery care were available in most of the visited facilities. However, the majority of them were not fully functioning for EmOC according to their level. Signal functions including administration of anticonvulsants and assisted vaginal delivery were missing in seven and five of the 12 health centers, respectively. Only one hospital met the criteria for comprehensive emergency obstetric care (performed cesarean section). Only 24% of the providers used partograph consistently. About 538 (32.3%) and 231 (13.8%) of the women received antenatal and delivery care from skilled providers, respectively. Most of the services were at health centers by nurses/midwives. At the time of the antenatal care, women received the important components of the services (percentage of users in bracket) like blood pressure checkup (79%), urine testing (35%), tetanus immunization (45%), iron supplementation (64%), birth preparedness counseling (51%) and HIV testing (71%). During delivery, 80% had their blood pressure measured, 78% were informed on labor progress, 89% had auscultation of fetal heartbeat

    Plasmodium falciparum accounts for approximately 60% of malaria cases in Ethiopia and artemether-lumefantrine has been used as a first-line treatment for uncomplicated P. falciparum malaria since 2004. The aim of this study was to assess the therapeutic efficacy of artemether-lumefantrine (AL) for the treatment of uncomplicated P. falciparum malaria in north-western Ethiopia. A 28-day one-arm, prospective evaluation of the clinical and parasitological response to the first-line treatment for uncomplicated P. falciparum malaria was conducted in Enfranze Health Centre in accordance with the 2009 WHO efficacy study guidelines. Patients were treated with a 3-day course of AL and clinical and parasitological parameters were monitored over a 28-day follow-up. All data from recruited patients were imported into an electronic data base and Kaplan-Meier survival analysis was used for analysing primary [early treatment failures (ETF), late clinical failure (LCF), late parasitological failures (LPF), and adequate clinical and parasitological response (ACPR)] and secondary (PCT, GCT and FCT) outcomes. Eighty patients were enrolled and all of them completed the 28-day follow-up period. The PCR-corrected cure rate was 95.0% (95% CI 87.0-98.4%) and there were two ETF, one LCF and three LPF. Two of the LPF were classified as re infections by PCR. Seventy three point seven five percent, 91.25 and 95% of patients had cleared their parasitaemia by days 1, 2, and 3, respectively, and 75, 91.25 and 96.25% of patients had cleared their fever by days 1, 2, and 3. All patients completely cleared their gametocytes by day 7. The relatively high cure rate, low proportion of patients still positive on day 3 as well as parasite clearance times in this study would indicate no imminent threat of artemisinin resistance development in the region. However, the threat of spreading or de novo development of artemisinin resistance warrants regular monitoring of drug efficacy throughout the region.

  14. Objective Tracking of Tropical Cyclones in the North-West Pacific Basin Based on Wind Field Information only

    Although only ca. 12% of the global insured losses of natural disasters occurred in Asia, there are two major reasons to be concerned about risks in Asia: a) The fraction of loss events was substantial higher with 39% of which 94% were due to atmospheric processes; b) Asia and especially China, is undergoing quick transitions and especially the insurance market is rapidly growing. In order to allow for the estimation of potential future (loss) impacts in East-Asia, in this study we further developed and applied a feature tracking system based on extreme wind speed occurrences to tropical cyclones, which was originally developed for extra-tropical cyclones (Leckebusch et al., 2008). In principle, wind fields will be identified and tracked once a coherent exceedance of local percentile thresholds is identified. The focus on severe wind impact will allow an objective link between the strength of a cyclone and its potential damages over land. The wind tracking is developed in such a way to be applicable also to course-gridded AOGCM simulation. In the presented configuration the wind tracking algorithm is applied to the Japanese reanalysis (JRA55) and TC Identification is based on 850hPa wind speeds (6h resolution) from 1979 to 2014 over the Western North Pacific region. For validation the IBTrACS Best Track archive version v03r8 is used. Out of all 904 observed tracks, about 62% can be matched to at least one windstorm event identified in JRA55. It is found that the relative amount of matched best tracks increases with the maximum intensity. Thus, a positive matching (hit rate) of above 98% for Violent Typhoons (VTY), above 90% for Very Strong Typhoons (VSTY), about 75% for Typhoons (TY), and still some 50% for less intense TCs (TD, TS, STS) is found. This result is extremely encouraging to apply this technique to AOGCM outputs and to derive information about affected regions and intensity-frequency distributions potentially changed under future climate conditions.

  15. Effects of groundwater lateral flow on land surface processes: a case study in Heihe River Basin, north-west of China

    As an important component of hydrologic cycle, groundwater is affected by topography, vegetation, climate condition, and anthropogenic activity. Groundwater horizontal convergence and divergence and vertical interaction with soil water result in variations of soil moisture, water and energy exchanges between the land surface and the atmosphere, which ultimately influences climate. In this work, a two-dimensional groundwater lateral flow scheme based on groundwater mass equation, is developed and incorporated into the land surface model CLM4.5 to investigate effects of groundwater lateral flow on land surface processes in a river basin. A 30-year simulation with groundwater lateral flow and a control run without the horizontal movement are conducted over Heihe River Basin, north-west China, from 1979 to 2012 using the developed model. Results show that with groundwater lateral flow, equilibrium distribution of groundwater table shows more spatial variability following topography rather than the water balance between local precipitation and evapotranspiration, and are much closer to well observations especially over middle reaches area. Along with shallower groundwater table over piedmont areas in the middle reaches, increased soil moisture is shown which alleviates the underestimation of CLM4.5 at here. Changes in evapotranspiration are occurred and it is mainly controlled by the variation of local surface soil moisture, since water is the major limitation factor of evapotranspiration over this arid area. Besides, groundwater lateral flow can change the distribution of surface runoff by changing the saturated area fraction of each model grid cell. Energy cycle also responds to the changes of hydrological cycle which redistributes the sensible heat flux and latent heat flux in the entire basin.

    A comparative box analysis based on a multi-decadal physical-biogeochemical hindcast simulation (1980-2009) was conducted to characterize the drivers of the spatial distribution of phytoplankton biomass and production in the north-west (NW) African upwelling system. Alongshore geostrophic flow related to large-scale circulation patterns associated with the influence of coastal topography is suggested to modulate the coastal divergence, and then the response of nutrient upwelling to wind forcing. In our simulation, this translates into a coastal upwelling of nitrate being significant in all regions but the Cape Blanc (CB) area. However, upwelling is found to be the dominant supplier of nitrate only in the northern Saharan Bank (NSB) and the Senegalo-Mauritanian (SM) regions. Elsewhere, nitrate supply is dominated by meridional advection, especially off Cape Blanc. Phytoplankton displays a similar behaviour with a supply by lateral advection which equals the net coastal phytoplankton growth in all coastal regions except the Senegalo-Mauritanian area. Noticeably, in the Cape Blanc area, the net coastal phytoplankton growth is mostly sustained by high levels of regenerated production exceeding new production by more than twofold, which is in agreement with the locally weak input of nitrate by coastal upwelling. Further offshore, the distribution of nutrients and phytoplankton is explained by the coastal circulation. Indeed, in the northern part of our domain (i.e. Saharan Bank), the coastal circulation is mainly alongshore, resulting in low offshore lateral advection of nutrients and phytoplankton. Conversely, lateral advection transports coastal nutrients and phytoplankton towards offshore areas in the latitudinal band off the Senegalo-Mauritanian region. Moreover, this latter offshore region benefits from transient southern intrusions of nutrient-rich waters from the Guinean upwelling.

    While climate change is confirmed to have serious impacts on agricultural production in many regions worldwide, researchers have proposed various measures that farmers can apply to cope with and adapt to those changes. However, it is often the case that not every adaptation measure would be practical and adoptable in a specific region. Farmers may have their own ways of managing and adapting to climate change that need to be taken into account when considering interventions. This study aimed to engage with farmers to: (1) better understand small-holder knowledge, attitudes and practices in relation to perceived or expected climate change; and (2) document cropping practices, climate change perceptions, constraints to crop production, and coping and adaptation options with existing climate variability and expected climate change. This study was conducted in 2015 in Sala Krau village near Pailin (12°52'N, 102°45'E) and Samlout (12°39'N, 102°36'E) of North-West Cambodia. The methods used were a combination of focus group discussions and one-on-one interviews where 132 farming households were randomly selected. We found that farmers were conscious of changes in climate over recent years, and had a good understanding of likely future changes. While farmers are aware of some practices that can be modified to minimize risk and cope with anticipated changes, they are reluctant to apply them. Furthermore; there are no government agricultural extension services provided at the village level and farmers have relied on each other and other actors in the value chain network for information to support their decision-making. There is a lack of knowledge of the principles of conservation agriculture that urgently require agricultural extension services in the region to build farmer ability to better cope and adapt to climate change.

    Emission of smoke and aerosol from open field burning of crop residue is a long-standing subject matter of atmospheric pollution. In this study, we proposed a new approach of estimating fuel load in the fire pixels and corresponding emissions of selected GHGs and aerosols i.e. CO2, CO, NO2, SO2, and total particulate matter (TPM) due to burning of crop residue under rice and wheat cropping systems in Punjab in north-west India from 2002 to 2012. In contrasts to the conventional method that uses RPR ratio to estimate the biomass, fuel load in the fire pixels was estimated as a function of enhanced vegetation index (EVI). MODIS fire products were used to detect the fire pixels during harvesting seasons of rice and wheat. Based on the field measurements, fuel load in the fire pixels were modelled as a function of average EVI using second order polynomial regression. Average EVI for rice and wheat crops that were extracted through Fourier transformation were computed from MODIS time series 16 day EVI composites. About 23 % of net shown area (NSA) during rice and 11 % during wheat harvesting seasons are affected by field burning. The computed average fuel loads are 11.32 t/ha (±17.4) during rice and 10.89 t/ha (±8.7) during wheat harvesting seasons. Calculated average total emissions of CO2, CO, NO2, SO2 and TPM were 8108.41, 657.85, 8.10, 4.10, and 133.21 Gg during rice straw burning and 6896.85, 625.09, 1.42, 1.77, and 57.55 Gg during wheat burning. Comparison of estimated values shows better agreement with the previous concurrent estimations. The method, however, shows its efficiency parallel to the conventional method of estimation of fuel load and related pollutant emissions.

    Little is known about the contributions of faith-based organisations (FBOs) to health systems in Africa. In the specialist area of eye health, international and domestic Christian FBOs have been important contributors as service providers and donors, but they are also commonly critiqued as having developed eye health systems parallel to government structures which are unsustainable. In this study, we use a health systems approach (quarterly interviews, a participatory sustainability analysis exercise and a social network analysis) to describe the strategies used by eye care practitioners in four hospitals of north-west Tanzania to navigate the government, church mission and donor rules that govern eye services delivery there. Practitioners in this region felt eye care was systemically neglected by government and therefore was 'all under the NGOs', but support from international donors was also precarious. Practitioners therefore adopted four main strategies to improve the sustainability of their services: (1) maintain 'sustainability funds' to retain financial autonomy over income; (2) avoid granting government user fee exemptions to elderly patients who are the majority of service users; (3) expand or contract outreach services as financial circumstances change; and (4) access peer support for problem-solving and advocacy. Mission-based eye teams had greater freedom to increase their income from user fees by not implementing government policies for 'free care'. Teams in all hospitals, however, found similar strategies to manage their programmes even when their management structures were unique, suggesting the importance of informal rules shared through a peer network in governing eye care in this pluralistic health system. Health systems research can generate new evidence on the social dynamics that cross public and private sectors within a local health system. In this area of Tanzania, Christian FBOs' investments are important, not only in terms of the population

    The forensic use of X-STRs requires the creation of allele and haplotype frequency databases in the populations where they are going to be used. Recently, an updated Spanish allele and haplotype frequency database for the new 17 X-STR panel has been created, being the only database available up to now for this new multiplex. In order to broaden the forensic applicability of the 17 X-STR panel, 513 individuals from four different populations located on the Atlantic Coast of Europe and North-West Africa have been studied, i.e. Brittany (France), Ireland, northern Portugal, and Casablanca (Morocco). Allele and haplotype frequency databases, as well as parameters of forensic interest for these populations are presented. The obtained results showed that the 17 X-STR panel constitutes a highly discriminative tool for forensic identification and kinship testing in the studied populations. Furthermore, we aimed to study if these populations located on the Atlantic coast actually share alike allele and haplotype frequency distributions since they have experienced genetic exchanges throughout history. This would allow creating larger forensic databases that include several genetically similar populations for its use in forensic casework. For this purpose, pairwise FST genetic distances between the analyzed populations and others from the Atlantic Coast previously studied with the 17 X-STR panel or the ten coincident markers included in the decaplex of the GHEP-ISFG were estimated. Our results suggest that certain nearby populations located on the European Atlantic coast could have underwent episodes of genetic interchange as they have not shown statistically significant differentiation between them. However, the population of Casablanca showed significant differentiation with the majority of the European populations. Likewise, the autochthonous Basque Country and Brittany populations have shown distinctive allele frequency distributions between them. Therefore, these

    The spatial variability and temporal trend in concentrations of the organochlorine pesticides (OCPs), hexachlorocyclohexane (HCH) and dichlorodiphenyltrichloroethane (DDT), in soils and agricultural corps were investigated on an intensive horticulture area in Hohhot, North-West China, from 2008 to 2011. The most frequently found and abundant pesticides were the metabolites of DDT (p,p'-DDE, p,p'-DDT, o,p'-DDT and p,p'-DDD). Total DDT concentrations ranged from ND (not detectable) to 507.41 ng/g and were higher than the concentration of total HCHs measured for the range of 4.84-281.44 ng/g. There were significantly positive correlations between the ∑DDT and ∑HCH concentrations (r (2)>0.74) in soils, but no significant correlation was found between the concentrations of OCPs in soils and clay content while a relatively strong correlation was found between total OCP concentrations and total organic carbon (TOC). β-HCH was the main isomer of HCHs, and was detected in all samples; the maximum proportion of β-HCH compared to ∑HCHs (mean value 54%) was found, suggesting its persistence. The α/γ-HCH ratio was between 0.89 and 5.39, which signified the combined influence of technical HCHs and lindane. Low p,p'-DDE/p,p'-DDT in N1, N3 and N9 were found, reflecting the fresh input of DDTs, while the relatively high o,p'-DDT/p,p'-DDT ratios indicated the agricultural application of dicofol. Ratios of DDT/(DDE+DDD) in soils do not indicate recent inputs of DDT into Hohhot farmland soil environment. Seasonal variations of OCPs featured higher concentrations in autumn and lower concentrations in spring. This was likely associated with their temperature-driven re-volatilization and application of dicofol in late spring.

    Full Text Available One of the fundamental challenges to implementing successful prevention of mother-tochild transmission (PMTCT programs in Nigeria is the uptake of PMTCT services at health facilities. Several issues usually discourage many pregnant women from receiving antenatal care services at designated health facilities within their communities. The CRS Nigeria PMTCT Project funded by the Global Fund in its Round 9 Phase 1 in Nigeria, sought to increase demand for HIV counseling and testing services for pregnant women at 25 supported primary health centers (PHCs in Kaduna State, North-West Nigeria by integrating traditional birth attendants (TBAs across the communities where the PHCs were located into the project. Community dialogues were held with the TBAs, community leaders and women groups. These dialogues focused on modes of mother to child transmission of HIV and the need for TBAs to refer their clients to PHCs for testing. Subsequently, data on number of pregnant women who were counseled, tested and received results was collected on a monthly basis from the 25 facilities using the national HIV/AIDS tools. Prior to this integration, the average number of pregnant women that were counseled, tested and received results was 200 pregnant women across all the 25 health facilities monthly. After the integration of TBAs into the program, the number of pregnant women that were counseled, tested and received results kept increasing month after month up to an average of 1500 pregnant women per month across the 25 health facilities. TBAs can thus play a key role in improving service uptake and utilization for pregnant women at primary health centers in the community – especially in the context of HIV/AIDS. They thus need to be integrated, rather than alienated, from primary healthcare service delivery.

    Full Text Available Giardia duodenalis, Cryptosporidium spp., and Entamoeba spp. are intestinal protozoa capable of infecting a range of host species, and are important causes of human morbidity and mortality. Understanding their epidemiology is important, both for public health and for the health of the animals they infect. This study investigated the occurrence of these protozoans in rhesus macaques (Macaca mulatta in India, with the aim of providing preliminary information on the potential for transmission of these pathogens between macaques and humans. Faecal samples (n = 170 were collected from rhesus macaques from four districts of North-West India. Samples were analysed for Giardia/Cryptosporidium using a commercially available direct immunofluorescent antibody test after purification via immunomagnetic separation. Positive samples were characterised by sequencing of PCR products. Occurrence of Entamoeba was investigated first by using a genus-specific PCR, and positive samples further investigated via species-specific PCRs for Entamoeba coli, Entamoeba histolytica, Entamoeba dispar and Entamoeba moshkovskii. Giardia cysts were found in 31% of macaque samples, with all isolates belonging to Assemblage B. Cryptosporidium oocysts were found in 1 sample, however this sample did not result in amplification by PCR. Entamoeba spp. were found in 79% of samples, 49% of which were positive for E. coli. Multiplex PCR for E. histolytica, E. dispar and E. moshkovskii, did not result in amplification in any of the samples. Thus in 51% of the samples positive at the genus specific PCR, the Entamoeba species was not identified. This study provides baseline information on the potential for transmission of these zoonotic parasites at the wildlife-human interface.

    Strong research evidence has shown that medical male circumcision significantly reduces heterosexual HIV acquisition among men. However, its effectiveness is enhanced by behavioural factors such as condom use. Currently, little is known of unprotected sex associated with male circumcision (MC) among alcohol-drinking tavern-going men, or whether engagement in unprotected sex may differ between men who have been traditionally circumcised and those who have been medically circumcised. The study sought to determine the relative importance of alcohol consumption and MC as correlates of unprotected sex and to compare the risk of engaging in unprotected sex between traditionally circumcised and medically circumcised tavern-going men from two rural villages in North-West province, South Africa. Data from 314 adult men (≥18 years) were analysed. The men were recruited from four bars/taverns using systematic sampling. They responded to questions regarding their demographic characteristics, alcohol consumption, circumcision status and method (where applicable), and engagement in unprotected sex. Descriptive analyses and bivariate and multivariate logistic regression analyses were conducted. Age, education, relationship status, alcohol consumption and traditional male circumcision (TMC) were independently and significantly associated with unprotected sex. Specifically, probable alcohol dependence and traditional circumcision were independent risk factors for engaging in unprotected sex among tavern-going men. Traditionally circumcised men had a higher risk of engaging in unprotected sex than medically circumcised men. Interventions aimed at reducing alcohol consumption, encouraging protective behaviour among men who have undergone TMC, and increasing condom use are needed in bar/tavern settings. HIV prevention education must be urgently incorporated into TMC programmes.

    Full Text Available Introduction: This study was conducted to determine the frequency and pattern of antimicrobial susceptibility of Shigella spp. isolated from pediatric hospital in two different time periods between March 1995 to March 1999 and March 2009 to March 2013 in North-West of Iran. Methods: The stool specimens were collected and examined for shigellosis by biochemical tests, and antibiogram was conducted according to Clinical and Laboratory Standards Institute protocol. One hundred and thirty-nine Shigella spp. isolated from year 1995 to 1999 and 38 Shigella spp. isolates collected from year 2009 to 2013 and examined for serotyping and antibiotic resistance pattern. Results: According to serotyping results Shigella flexneri isolated in 98.6% of isolates in the first time period, followed by Shigella boydii and Shigella sonnei (0.7% but in the second time period just 47.3% were S. flexneri and 39.5% were S. sonnei, 7.9% were S. boydii and 5.3% of isolates were Shigella dysenteriae. Results indicated significantly increase in resistance to ceftizoxime, chloramphenicol, and amikacin (P = 0.004, 0.010, and 0.004 respectively, also, in Shigella isolates isolated in the second time period showed an increase in multidrug resistant (MDR isolate and frequency of MDR isolates increased to 95.0% in the second time period. Conclusion: We are facing with the increase in resistance to antibiotics in Shigella spp. especially MDR isolates. These results showed changing pattern of resistance in Shigella isolates and needs for planning and design antibiotics stewardships for controlling Shigellosis, especially in pediatric hospitals.

    Sex trafficking is a contemporary issue in both developed and developing countries. The number of trafficked women and young girls has increased globally. Females aged 18-25 are the most targeted group of trafficking. Although the problem is evident in Ethiopia, there are no studies that explored sex trafficking awareness among females. Therefore, the aim of this study was to assess sex trafficking awareness and associated factors among youth females in Bahir Dar town, North-West Ethiopia. A community based cross-sectional study design was employed to collect data from February 1st-30th 2012 from a total of 417 youth females. The participants in the study were selected using systematic random sampling techniques. A structured Amharic questionnaire was used to collect data. Data were entered, cleaned and analyzed using SPSS 16.0. Descriptive statistics were used to describe data. Logistic regression analysis was used to identify factors associated with sex trafficking awareness. Two hundred forty-nine (60%) of the participants reported that they had heard or read about sex trafficking. Television (64%), friends (46%) and radio (39%) were the most frequently mentioned sources of information about sex trafficking. About 87% and 74% of the participants mentioned friends and brokers respectively as mediators of sex trafficking. Having TV at home (AOR = 2. 19, 95% CI: 1.31-3.67), completing grade 10 or more (AOR = 2. 22, 95% CI: 1.18-4.17), taking training on gender issues (AOR = 3. 59, 95% CI: 2.11-6.10) and living together with parents (AOR = 3. 65, 95% CI: 1.68-7.93) were factors found associated with sex trafficking awareness. In this study, sex trafficking awareness was low among youth females. Having TV at home, living together with someone and being trained on gender issues were predictors of sex trafficking awareness. Therefore, providing education about sex trafficking will help to increase sex trafficking awareness among youth females.

    Full Text Available In many developing countries, proper hygiene is not strictly implemented when animals are slaughtered and meat products become contaminated. Contaminated meat may contain Escherichia coli (E. coli O157:H7 that could cause diseases in humans if these food products are consumed undercooked. In the present study, a total of 94 confirmed E. coli O157:H7 isolates were subjected to the enterobacterial repetitive intergenic consensus (ERIC polymerase chain reaction (PCR typing to generate genetic fingerprints. The ERIC fragments were resolved by electrophoresis on 2% (w/v agarose gels. The presence, absence and intensity of band data were obtained, exported to Microsoft Excel (Microsoft Office 2003 and used to generate a data matrix. The unweighted pair group method with arithmetic mean (UPGMA and complete linkage algorithms were used to analyze the percentage of similarity and matrix data. Relationships between the various profiles and/or lanes were expressed as dendrograms. Data from groups of related lanes were compiled and reported on cluster tables. ERIC fragments ranged from one to 15 per isolate, and their sizes varied from 0.25 to 0.771 kb. A large proportion of the isolates produced an ERIC banding pattern with three duplets ranging in sizes from 0.408 to 0.628 kb. Eight major clusters (I–VIII were identified. Overall, the remarkable similarities (72% to 91% between the ERIC profiles for the isolate from animal species and their corresponding food products indicated some form of contamination, which may not exclude those at the level of the abattoirs. These results reveal that ERIC PCR analysis can be reliable in comparing the genetic profiles of E. coli O157:H7 from different sources in the North-West Province of South Africa.

    Full Text Available From January 2011 to December 2013, we constructed a comprehensive pCO2 dataset based on voluntary observing ship (VOS measurements in the Western English Channel (WEC. We subsequently estimated surface pCO2 and air–sea CO2 fluxes in north-west European continental shelf waters using multiple linear regressions (MLRs from remotely sensed sea surface temperature (SST, chlorophyll a concentration (Chl a, the gas transfer velocity coefficient (K, photosynthetically active radiation (PAR and modeled mixed layer depth (MLD. We developed specific MLRs for the seasonally stratified northern WEC (nWEC and the permanently well-mixed southern WEC (sWEC and calculated surface pCO2 with relative uncertainties of 17 and 16 μatm, respectively. We extrapolated the relationships obtained for the WEC based on the 2011–2013 dataset (1 temporally over a decade and (2 spatially in the adjacent Celtic and Irish Seas (CS and IS, two regions which exhibit hydrographical and biogeochemical characteristics similar to those of WEC waters. We validated these extrapolations with pCO2 data from the SOCAT database and obtained relatively robust results with an average precision of 4 ± 22 μatm in the seasonally stratified nWEC and the southern and northern CS (sCS and nCS, but less promising results in the permanently well-mixed sWEC, IS and Cap Lizard (CL waters. On an annual scale, seasonally stratified systems acted as a sink of CO2 from the atmosphere of −0.4, −0.9 and −0.4 mol C m−2 year−1 in the nCS, sCS and nWEC, respectively, whereas, permanently well-mixed systems acted as source of CO2 to the atmosphere of 0.2, 0.4 and 0.4 mol C m−2 year−1 in the sWEC, CL and IS, respectively. Air–sea CO2 fluxes showed important inter-annual variability resulting in significant differences in the intensity and/or direction of annual fluxes. We scaled the mean annual fluxes over six provinces for the last decade and obtained the first annual average uptake of

    Full Text Available Abstract Background Streptococcus pneumoniae is a leading cause of invasive infection in young children causing morbidity and mortality. Active surveillance systems of invasive pneumococcal disease (IPD are recommended worldwide. The aim of this study was to estimate the current incidence of IPD and to describe the serotype distribution and the antimocrobial susceptibility of S. pneumoniae isolates in children aged less than 5 years residing in North-West Lombardy, Italy. Methods A twelve-month prospective active surveillance system recruited all children aged less than 5 years admitted for suspicion of IPD at emergency room of ten hospitals located in the monitored area. Blood samples were taken in all participants for confirmation of IPD based on isolation of S. pneumoniae from blood. Pneumococcal meningitis and sepsis were additionally confirmed by cerebrospinal fluid analysis. Serotyping and antimicrobial susceptibility testing were performed on isolates from blood. Results A total of 15 confirmed cases of IPD were detected among 135 recruited children, including pneumonia (n = 8, bacteremia (n = 4, sepsis (n = 2 and meningitis (n = 1. The annual IPD incidence rate was 50.0/100,000 (95%CI, 30.5-82.5/100,000. Incidence was 58.3/100,000 (28.8-120.1/100,000 among children aged less than 2 years and 44.4/100,000 (22.9-87.5/100,000 among children aged 2–4 years. Thirteen isolates were typified. The most common serotype was 19A (23.1% that together with serotypes 1, 7F and 19F accounted for 69.2% of typified isolates. Serotypes 14, 23F, 12B and 15C were also identified. The 7- and 13-valent pneumococcal conjugate vaccines covered respectively 30.8% and 84.6% of typified IPD cases. One isolate (serotype 15C was penicillin-resistant and caused meningitis. Conclusions The inclusion of the 13-valent pneumococcal conjugate vaccine in immunization programs of young children might be considered to reduce incidence and morbidity

    To assess women's knowledge and attitude toward Ethiopian current abortion law. A quantitative, community-based cross-sectional survey. Women of reproductive age in three selected lower districts in Bahir Dar, North-West Ethiopia, were included. Multi-stage simple random sampling and simple random sampling were used to select the districts and respondents, respectively. Data were collected using a structured questionnaire comprising questions related to knowledge and attitude toward legal status of abortion and cases where abortion is currently allowed by law in Ethiopia. Descriptive statistics were used to summarize the data and multivariable logistic regression computed to assess the magnitude and significance of associations. Of 845 eligible women selected, 774 (92%) consented to participate and completed the interview. A total of 512 (66%) women were aware of the legal status of the Ethiopian abortion law and their primary sources of information were electronic media such as television and radio (43%) followed by healthcare providers (38.7%). Among women with awareness of the law, 293 (57.2%) were poor in knowledge, 188 (36.7%) fairly knowledgeable, and 31 (6.1%) good in knowledge about the cases where abortion is allowed by law. Of the total 774 women included, 438 (56.5%) hold liberal and 336 (43.5%) conservative attitude toward legalization of abortion. In the multivariable logistic regression, age had a significant association with knowledge, whereas occupation had a significant association with attitude toward the law. Women who had poor knowledge toward the law were more likely to have conservative attitude toward the law (adjusted odds ratio, 0.40; 95% confidence interval, 0.23-0.61). Though the Ethiopian criminal code legalized abortion under certain circumstances since 2005, a significant number of women knew little about the law and several protested legalization of abortion. Countries such as Ethiopia with high maternal mortality records need to lift

    Full Text Available Abstract Background Insecticide-treated nets (ITN are one of the most effective measures for preventing malaria. Mass distribution campaigns are being used to rapidly increase net coverage in at-risk populations. This study had two purposes: to evaluate the impact of a universal coverage campaign (UCC of long-lasting insecticidal nets (LLINs on LLIN ownership and usage, and to identify factors that may be associated with inadequate coverage. Methods In 2011 two cross-sectional household surveys were conducted in 50 clusters in Muleba district, north-west Tanzania. Prior to the UCC 3,246 households were surveyed and 2,499 afterwards. Data on bed net ownership and usage, demographics of household members and household characteristics including factors related to socio-economic status were gathered, using an adapted version of the standard Malaria Indicator Survey. Specific questions relating to the UCC process were asked. Results The proportion of households with at least one ITN increased from 62.6% (95% Confidence Interval (CI = 60.9-64.2 before the UCC to 90.8% (95% CI = 89.0-92.3 afterwards. ITN usage in all residents rose from 40.8% to 55.7%. After the UCC 58.4% (95% CI = 54.7-62.1 of households had sufficient ITNs to cover all their sleeping places. Households with children under five years (OR = 2.4, 95% CI = 1.9-2.9 and small households (OR = 1.9, 95% CI = 1.5-2.4 were most likely to reach universal coverage. Poverty was not associated with net coverage. Eighty percent of households surveyed received LLINs from the campaign. Conclusions The UCC in Muleba district of Tanzania was equitable, greatly improving LLIN ownership and, more moderately, usage. However, the goal of universal coverage in terms of the adequate provision of nets was not achieved. Multiple, continuous delivery systems and education activities are required to maintain and improve bed net ownership and usage.

    The objective of this study was to characterize the declining Somba cattle population in its production system context. Two-hundred-twenty-four (224) cattle farm-households were surveyed in the Boukombe district, the natural habitat of the breed in North-West Benin. Information on their socioeconomic characteristics and on their herd management practices were recorded using a semi-structured questionnaire. In addition, 15 body measurements were recorded from 102 adult cattle. Three types of breeders were distinguished: the owners-herders (54.0 %); the absentee owners (40.2 %) and the professional herders (5.8 %). The average cattle herd sizes were 4.7 ± 3.70 and 58.6 ± 22.83 heads for owner-managed and entrusted herds, respectively. Offtakes were more associated with sociocultural purposes (75.5 %) than market. While crop farming was the main occupation and income source of their owners, the Somba cattle were used for ploughing during the rainy season. In contrast to the widely accepted belief that this indigenous genetic resource is mainly threatened by crossbreeding and/or replacement, our findings suggest high mortalities due to diseases, feed and water shortages and poor reproduction management as the main causes of the decline of this cattle population. Somba cattle generally have short horns and a small body size. However, bulls have significantly (P ≤ 0.05) longer horns (21.2 ± 16.44 cm against 13.9 ± 7.21 cm), higher height at withers (99.7 ± 6.97 cm against 95.9 ± 5.76 cm) and body length (149.7 ± 12.87 cm against 146.8 ± 11.01 cm) than cows. All surveyed farmers expressed their willingness and readiness to participate in and contribute materially or financially to any program towards a sustainable use and preservation of this breed which they perceived as hardy and embedded in their culture. We therefore argue that strategies for its sustainable use and conservation should consist of simultaneously

    Full Text Available The Norite Koppies Bushveld vegetation type boasts a distinctive and contrasting topography and species composition easily distinguished from that of surrounding areas. A phytosociological study was done on the leased mining area of the Impala Platinum Mining Company north of Rustenburg in the North-West Province. Similar norite koppies, situated west of the Norite Koppies Bushveld vegetation, and not yet mapped by Mucina & Rutherford (2006, were identified in the study area and phytosociologically described. Six plant communities and two subcommunities were identified. Multivariate statistical analyses (correspondence analyses confirmed that the species composition of these areas corresponds with and does therefore form part of the Norite Koppies Bushveld vegetation type as described by Mucina & Rutherford (2006. Some of these communities contain Boscia albitrunca, a protected plant species, and should therefore be considered as areas with conservation value.

    Optimal water management practices and strategies, in arid and semi-arid environments, are often hindered by a lack of quantitative and qualitative understanding of hydrological processes. Moreover, progressive overexploitation of groundwater resources to meet agricultural, industrial, and domestic requirements is drawing concern over the sustainability of such exhaustive abstraction levels, especially in environments where groundwater is a major source of water. NASA's GRACE (gravity recovery and climate change experiment) mission, since March 2002, has advanced the understanding of hydrological events, especially groundwater depletion, through integrated measurements and modeling of terrestrial water mass. In this study, GLDAS variables (rainfall rate, evapotranspiration rate, average soil moisture), and TRMM 3B42.V7A precipitation satellite data, were used in combination with 95 GRACE-generated gravitational anomalies maps, to quantify total water storage change (TWSC) and groundwater storage change (GWSC) from January 2003 to December 2010 (excluding June 2003), in the North-Western Sahara Aquifer System (NWSAS) and Tindouf Aquifer System in northwestern Africa. Separately processed and computed GRACE products by JPL (Jet Propulsion Laboratory, NASA), CSR (Center of Space Research, UT Austin), and GFZ (German Research Centre for Geoscience, Potsdam), were used to determine which GRACE dataset(s) best reflect total water storage and ground water changes in northwest Africa. First-order estimates of annual TWSC for NWSAS (JPL: +5.297 BCM; CSR: -5.33 BCM; GFZ: -9.96 BCM) and Tindouf Aquifer System (JPL: +1.217 BCM; CSR: +0.203 BCM; GFZ: +1.019 BCM), were computed using zonal averaging over a span of eight years. Preliminary findings of annual GWSC for NWSAS (JPL: +2.45 BCM; CSR: -2.278 BCM; GFZ: -6.913 BCM) and Tindouf Aquifer System (JPL: +1.108 BCM; CSR: +0.094 BCM; GFZ: +0.910 BCM), were calculating using a water budget approach, parameterized by GLDAS

    Designing a vessel to sail oceans for an extended period of time requires statistical estimation on different hull responses to waves. To meet the requirement, it is necessary to accurately identify hydrographic conditions (particularly waves) which are considered to be encountered by the vessel. This paper makes clear the statistical characteristics of the wave statistics table presented by Fang et al, and compares them with other processes for discussion. This statistics collection is based on data collected in China, Hong Kong and Japan, including those collected in the Sea of Japan, the Yellow Sea, the North Sea, the East China Sea and the South China Sea. It was found that these data provide results slightly lower than the long-term estimation values derived from data of the global wave statistics (GWS) prepared by Hogben et al. The cause for this was found attributable to the format of the statistical data, especially setting of wave height classes. However, since the data provided by Fang et al include items of detailed information on small sea areas near the Chinese coast lines, the data are thought to provide useful information source in investigating long-term hull response characteristics relative to spatial spread of the sea areas in the North-west Pacific Ocean. 15 refs., 5 figs., 2 tabs.

    The Active Crater at Rincon de la Vieja volcano, Costa Rica, reaches an elevation of 1750 m and contains a warm, hyper-acidic crater lake that probably formed soon after the eruption of the Rio Blanco tephra deposit approximately 3500 years before present. The Active Crater is buttressed by volcanic ridges and older craters on all sides except the north, which dips steeply toward the Caribbean coastal plains. Acidic, above-ambient-temperature streams are found along the Active Crater's north flank at elevations between 800 and 1000 m. A geochemical survey of thermal and non-thermal waters at Rincon de la Vieja was done in 1989 to determine whether hyper-acidic fluids are leaking from the Active Crater through the north flank, affecting the composition of north-flank streams. Results of the water-chemistry survey reveal that three distinct thermal waters are found on the flanks of Rincon de la Vieja volcano: acid chloride-sulfate (ACS), acid sulfate (AS), and neutral chloride (NC) waters. The most extreme ACS water was collected from the crater lake that fills the Active Crater. Chemical analyses of the lake water reveal a hyper-acidic (pH ~ 0) chloride-sulfate brine with elevated concentrations of calcium, magnesium, aluminum, iron, manganese, copper, zinc, fluorine, and boron. The composition of the brine reflects the combined effects of magmatic degassing from a shallow magma body beneath the Active Crater, dissolution of andesitic volcanic rock, and evaporative concentration of dissolved constituents at above-ambient temperatures. Similar cation and anion enrichments are found in the above-ambient-temperature streams draining the north flank of the Active Crater. The pH of north-flank thermal waters range from 3.6 to 4.1 and chloride:sulfate ratios (1.2-1.4) that are a factor of two greater than that of the lake brine (0.60). The waters have an ACS composition that is quite different from the AS and NC thermal waters that occur along the southern flank of Rincon

    In terms of total terrestrial sequestered carbon, the global soils and forests are recognized as the predominant C sinks. Even though urban forests stored a relatively small proportion of the total terrestrial C, they also provide other important ecosystem services such as improving air quality, cooling effect in buildings and aesthetics. Thus in view of these environmental services the quantification of urban tree is increasingly viewed as essential to the understanding of how these ecosystem services can be optimized. The aims of this paper are to: i) quantify the spatial-temporal distribution of urban forests in Northwest Sydney using remote sensing techniques; ii) determine the total urban C-storage over many decades; iii) apply UFORE model to estimate air pollutant removal ability of urban forest. The results revealed the estimated total trees in Northwest Sydney in 2011was approximately 2.3 million. These urban forests potentially store an estimated 1.3 million tons of carbon in various forms such as biomass, soil carbon, etc. The relative carbon sequestration rate of these trees was estimated to be about 20,500 tC/yr (equivalent to AUD 467,000/year). Furthermore, the results show that trees near buildings can potentially avoid AUD 12.9 million of energy cost every year and 70000 tons of carbon emission, the latter which is equivalent to additional savings of nearly AUD 1.6 million per year. We also estimated that urban forests in the study area could potentially remove about 44,600 tons of pollutants (mainly greenhouse gases) annually equivalent to a saving of about AUD 409 million per year. Thus the results reveal the spatial-temporal variation of urban vegetation in the last twenty year between 1991 and 2011. The study has showcased the importance and potential role of urban forests in preserving carbon and thus reducing GHG emissions into atmosphere. Furthermore, these results highlight the significant value of urban forests in term of pollutant removal

    Full Text Available The study carried out in Menchum River valley, Northwest Region of Cameroon had as objective to analyze the profitability and establish the marketing channels of rice in this zone. The study in-terviewed a total of 126 respondents, selected purposively and using the snow ball sampling tech-nique. Results showed that the main actors involved in the rice marketing channel were; produc-ers, wholesalers, hullers, retailers and consumers. The production and marketing of rice in the zone is a profitable venture. In terms of profitability in the rice business, millers obtain a relatively large profit margin as a percentage of the cost price (18.69% followed by the producers (12.77%, wholesalers (8.5% then retailers (8.33%. The average profit margin per bag of 50kg was; 1054.5FCFA (franc Communauté financière d'Afrique for producers, 1963.5 FCFA for millers; 1100 FCFA for the wholesalers and 1250FCFA for the retailers. The principal constraints identi-fied by the study that affects actors of the rice channel were, bad condition of the roads, lack of capital, poor quality of rice. It was recommended that there should be improvement in infrastruc-ture.

    Combined records of snow accumulation rate, δ18O and deuterium excess were produced from several shallow ice cores and snow pits at NEEM (North Greenland Eemian Ice Drilling), covering the period from 1724 to 2007. They are used to investigate recent climate variability and characterise the isotope-temperature relationship. We find that NEEM records are only weakly affected by inter-annual changes in the North Atlantic Oscillation. Decadal δ18O and accumulation variability is related to North Atlantic sea surface temperature and is enhanced at the beginning of the 19th century. No long-term trend is observed in the accumulation record. By contrast, NEEM δ18O shows multidecadal increasing trends in the late 19th century and since the 1980s. The strongest annual positive δ18O values are recorded at NEEM in 1928 and 2010, while maximum accumulation occurs in 1933. The last decade is the most enriched in δ18O (warmest), while the 11-year periods with the strongest depletion (coldest) are depicted at NEEM in 1815-1825 and 1836-1846, which are also the driest 11-year periods. The NEEM accumulation and δ18O records are strongly correlated with outputs from atmospheric models, nudged to atmospheric reanalyses. Best performance is observed for ERA reanalyses. Gridded temperature reconstructions, instrumental data and model outputs at NEEM are used to estimate the multidecadal accumulation-temperature and δ18O-temperature relationships for the strong warming period in 1979-2007. The accumulation sensitivity to temperature is estimated at 11 ± 2 % °C-1 and the δ18O-temperature slope at 1.1 ± 0.2 ‰ °C-1, about twice as large as previously used to estimate last interglacial temperature change from the bottom part of the NEEM deep ice core.

    Full Text Available Introduction Heavy metals are the most toxic pollutants in aquatic ecosystems. This contamination can result from the release of heavy metal elements during alteration and weathering of ultramafic and mafic rocks (ophiolite zones. Among the important metals and pollutants in the ophiolite; chromium, cobalt, nickel, iron, magnesium, manganese, zinc and copper could be noted. Basically, a mass of serpentine consists of serpentine, amphibole, talc, chlorite, magnetite, and the remainder of olivine, pyroxene and spinel (Kil et al., 2010. In such areas, the prevailing cold climate, during the serpentinization, chloritization and epidotiization, the activity of the solvent, such as chloride, fluoride, carbonates, sulfide, sulfosalt would be able to import the elements such as magnesium and iron, copper and zinc into the soil and groundwater. The study area is located in northwestern Iran. This area is located in the northwest of the city of Khoy. Because of the proximity to the north and northwest Khoy plains with ophiolite rocks, the soil of this region could possibly show the potential of contamination with heavy metals. Due to the toxicity and disease of unauthorized grades of these elements in groundwater in the study area, this study is focused on the more contaminated groundwater of the areas. Materials and methods In this study, over a period of 5 days, sampling from 42 water sources, including fountains, aqueducts, wells, piezometers and wells in operation, was performed. The container was washed with acid and then rinsed 3 times with the water sample. The pH and temperature of the water in the samples was measured in the field. Then to each of the samples was taken from 2 to 5 ml of concentrated nitric acid (This causes that the metal elements would not adsorbed or precipitated by these particles and pH of the samples was measured with litmus paper to reach level 2. This was done to ensure the consolidation of the water samples. Analysis of

    Reflection exploration of earthquakes was conducted in the continental shelf off the north-west Australia, and a report is made concerning the processing of the acquired data. A GI gun was used as the vibration source, and a wave quite similar to a pulse was generated. Hydrophones were arranged with group intervals of 12.5m, and high-resolution field data were acquired. An analog low cut filter was used to suppress the large-amplitude swell noise attributable to sea conditions. A digital filter was designed for the purpose of eliminating coherent noises from other survey ships. At the ultimate stage the f-k filter was applied to each of the shot records, and the effectiveness was verified. The traverse line was as long as 6700km and therefore the design window was set relatively long at 2.0-4.0s in the residual static correction phase. It was found that this setup is effective in improving the continuity of the reflection surface. 5 figs., 1 tab.

  6. Biogas digestate and its economic impact on farms and biogas plants according to the upper limit for nitrogen spreading—the case of nutrient-burdened areas in north-west Germany

    Directory of Open Access Journals (Sweden)

    Sebastian Auburger

    2015-11-01

    Full Text Available At the end of 2012, an expert group presented its evaluation of the forthcoming amendment of the German Fertilizer Ordinance (DüV. The new proposal intends to include manure of plant origin in the calculation of the upper limit for nitrogen spreading, determined to be 170 kg per hectare. This would particularly affect regions of north-west Germany that are characterized by intensive animal husbandry and biogas production. This would lead to increased costs of the disposal of manure and the use of agricultural land, especially for pig farms and biogas producers. A spatial model of nutrient distribution demonstrates the regional impacts of the amendment, and example calculations at an enterprise level show that many farmers would no longer be able to suitably pay for the factors used. Monte Carlo analysis shows a relatively high probability that only successful pig farmers and biogas producers would be able to compensate for the rising costs of transport and land use in a sustainable manner. Successful piglet producers would improve their relative competitiveness compared to biogas producers and especially to pig-fattening enterprises. The adoption of new strategies should factor in both the water protection requirements and the ability of the affected farms to evolve and grow on a sustainable basis.

    The aim of the present study is a thorough comparison of hydrometry's conventional and innovative methods-tools for river flow monitoring. A case study was conducted in Stara river at Agios Germanos monitoring station (northwest Greece), in order to investigate possible deviations between conventional and innovative methods-tools on river flow velocity and discharge. For this study, two flowmeters were used, which manufac-tured in 2013 (OTT Messtechnik Gmbh, 2013), as follows: a) A conventional propeller flow velocity meter (OTT-Model C2) which is a me-chanical current flow meter with a certification of calibration BARGO, operated with a rod and a relocating device, along with a digital measuring device including an elec-tronic flow calculator, data logger and real time control display unit. The flowmeter has a measurement velocity range 0.025-4.000 m/s. b) An innovative electromagnetic flowmeter (OTT-Model MF pro) which it is con-sisted of a compact and light-weight sensor and a robust handheld unit. Both system components are designed to be attached to conventional wading rods. The electromag-netic flowmeter uses Faraday's Law of electromagnetic induction to measure the process flow. When an electrically conductive fluid flows along the meter, an electrode voltage is induced between a pair of electrodes placed at right angles to the direction of mag-netic field. The electrode voltage is directly proportional to the average fluid velocity. The electromagnetic flowmeter was operated with a rod and relocating device, along with a digital measuring device with various logging and graphical capabilities and vari-ous methods of velocity measurement (ISO/USGS standards). The flowmeter has a measurement velocity range 0.000-6.000 m/s. The river flow data were averaged over a pair measurement of 60+60 seconds and the measured river water flow velocity, depths and widths of the segments were used for the estimation of cross-section's mean flow velocity in each measured

    Based on the investigation data of the vegetations in Hegou valley in Wuqi County of Shaanxi Province, this paper studied the vegetation characteristics on the five typical micro-topography categories including shallow gully, gully, collapse, platform, and scarp in the loess area of north Shaanxi, with the undisturbed slope as the control. There existed distinct differences in the species composition, quantitative characteristics, and species diversity of plant communities on the five typical micro-topography categories and the undisturbed slope. After twelve years of enclosure recovery, the study area formed herbaceous plant community, with Artemisia sacrorum and Artemisia giraldii as the dominant species. Among the main companion species, shrubs such as Prinsepia uniflora and Caragana korshinskii were found in scarp and gully, and hygrophyte Phragmites australis appeared in platform. The coverage, height, and biomass of the plant communities on most of the micro-topography categories, especially on the gully and collapse, were larger than those on the undisturbed slope. The Shannon index on the micro-topography categories and undisturbed slope was in the order of scarp > gully > shallow gully > undisturbed slope > platform > collapse.

    The worldwide increase in commercial fisheries and its impact on ecosystems as well as inefficient fishery management have led to overfishing and frequent breakdown of traditional fish stocks. In this context, an analysis of Khuzestan inshore fisheries data covering the years 2002–2011, was conducted in reliance on testing for occurrence of the fishing down marine food webs (FDMFW) phenomenon in the North of Persian Gulf Large Marine Ecosystem (LME). In this study, the mean trophic level (mTL) and the fishing-in-balance (FIB)-index of Khuzestan landings during this period of time were estimated using the trophic level of 47 fishery resources. Increase in total landings (Y) was observed, which explained the high fishing yield in major fishery resources (especially demersal). Moreover, the moderates decreasing trend in mTL per decade, and the increasing trend in FIB-index were observed. The status of fishery resources in Khuzestan inshore waters (under exploited but not overexploited), the rise inY, FIB and slightly drop in mTL can be considered as indirect indicators of the fishing impacts on the trophic structure of marine communities. Based on this result, probability occurrence of FDMFW process in Khuzestan inshore waters is low to some extent. However, we suggest that the goal of management programs in Khuzestan inshore waters should prevent the continuance of this trend in the long-term using an ecosystem-based approach.

    Full Text Available This paper deals with the first description of an albanerpetontid amphibian from the Early Miocene locality Merkur–North. The material comes from grey calcareous marls at the base of the so-called “Main Brown Coal Seam”. The marls are interpreted as reworked volcanic ash (Most Formation. The genus Albanerpeton was already known from this locality, but the material has never been described or illustrated. The new material of dentaries extends our knowledge about the state of the Merkur–North population. The extinct clade of Albanerpetontidae represents primarily Laurasian lissamphibians known from the Middle Jurassic to Pliocene periods. The Late Oligocene to Early Miocene albanerpetontids of central Europe belong to the species A. inexpectatum. The material described here allocated a big similarity closed to this species.

  12. Development and Application of an Objective Tracking Algorithm for Tropical Cyclones over the North-West Pacific purely based on Wind Speeds

    Tropical Cyclones over East Asia have huge socio-economic impacts due to their strong wind fields and large rainfall amounts. Especially, the most severe events are associated with huge economic losses, e.g. Typhoon Herb in 1996 is related to overall losses exceeding 5 billion US (Munich Re, 2016). In this study, an objective tracking algorithm is applied to JRA55 reanalysis data from 1979 to 2014 over the Western North Pacific. For this purpose, a purely wind based algorithm, formerly used to identify extra-tropical wind storms, has been further developed. The algorithm is based on the exceedance of the local 98th percentile to define strong wind fields in gridded climate data. To be detected as a tropical cyclone candidate, the following criteria must be fulfilled: 1) the wind storm must exist for at least eight 6-hourly time steps and 2) the wind field must exceed a minimum size of 130.000km2 for each time step. The usage of wind information is motivated to focus on damage related events, however, a pre-selection based on the affected region is necessary to remove events of extra-tropical nature. Using IBTrACS Best Tracks for validation, it is found that about 62% of all detected tropical cyclone events in JRA55 reanalysis can be matched to an observed best track. As expected the relative amount of matched tracks increases with the wind intensity of the event, with a hit rate of about 98% for Violent Typhoons, above 90% for Very Strong Typhoons and about 75% for Typhoons. Overall these results are encouraging as the parameters used to detect tropical cyclones in JRA55, e.g. minimum area, are also suitable to detect TCs in most CMIP5 simulations and will thus allow estimates of potential future changes.

    By analyzing the characteristics of development, structural evolution and reservoir beds of the residual carbonate strata, this study shows that the residual carbonate strata in the Yingmaili low uplift are favorable oil and gas accumulation series in the Tabei (northern Tarim uplift) uplift. There are different patterns of hydrocarbon accumulation on the northern and southern slopes of the Yingmaili low uplift. The north-south differentiation of oil reservoirs were caused by different lithologies of the residual carbonate strata and the key constraints on the development of the reservoir beds. The Mesozoic terrestrial organic matter in the Kuqa depression and the Palaeozoic marine organic matter in the Manjiaer sag of the Northern depression are the major hydrocarbon source rocks for the northern slope and southern slope respectively. The hydrocarbon accumulation on the northern and southern slopes is controlled by differences in maturity and thermal evolution history of these two kinds of organic matter. On the southern slope, the oil accumulation formed in the early stage was destroyed completely, and the period from the late Hercynian to the Himalayian is the most important time for hydrocarbon accumulation. However, the time of hydrocarbon accumulation on the northern slope began 5 Ma B.P. Carbonate inner buried anticlines reservoirs are present on the southern slope, while weathered crust and paleo-buried hill karst carbonate reservoirs are present on the northern slope. The northern and southern slopes had different controlling factors of hydrocarbon accumulation respectively. Fracture growth in the reservoir beds is the most important controlling factor on the southern slope; while hydrocarbon accumulation on the northern slope is controlled by weathered crust and cap rock.

    Full Text Available Addressing the underlying common processes within aquatic systems located in the same geographical region has long been used as a tool for the advancement of limnology. A limnological study of the Merja Sidi Boughaba in 2009 has shown that there are many common features between the physico-chemical and biological conditions of this site and previous data reported from some of the wetlands of the Doñana National Park (South-West Spain. Both are Ramsar sites located on extensive dune systems of the Atlantic coast with a Mediterranean climate. They have a common palaeoenvironmental history that is largely responsible for their similar hydrology and water composition. Oceanic influence has probably produced a slight disproportion of Mg2+ over Ca2+ through airborne sea salt deposition and the surface evaporation of groundwater feeding these wetlands during annual flood and drought cycles. The wide spectrum of environmental conditions encountered in the Doñana wetlands is epitomised by the Merja Sidi Boughaba, where water and sediment gradually change in the same water body from north to south: from humic-coloured waters and a sandy substrate to a calcium-rich substrate with turbid and silted waters which eventually dry out. As a consequence, the community of submersed macrophytes is very rich and dominated by dense charophyte beds. The high primary production coupled with high biodiversity found in the Merja Sidi Boughaba is also shared by the Doñana wetlands. The high conservation status of both sites enables a useful comparison to be made of the water quality of shallow aquatic systems at a regional scale which, contrary to the trophic classifications developed for deep stratified lakes in temperate regions, is not based on regressions between the concentrations of chlorophyll and total phosphorus (Tot-P but on the proportions of dissolved and particulate P pools. In these Mediterranean sites, nutrients are more efficiently recycled through the

    There are large amount of salinized soil in north-west region.Salinization is a main reason that cause a bad ecological environment and prevent to develop sustainable agriculture.The reasons for salinization is variable.Because salinity soil have characteis such as intensified salinity degree,complicated salt contents,weak rain off salt-washing off,obvious salt surface concentration,second salinity distributed more often and water movement unable to take away the salinity in the soil.So it is more hard to prevent salinization inland than in areas near sea.After 20 years of studies,we have taken a biological approach involving planting special salt tolerant crops,through which take away salt increase green-coverd areas as to prevent salts up to the subsoil,therefore to improve soil production efficiently.Mean while,we insist on study.mechanic of plant salt-resist and measures about how to use of these plants so that a practical and theoretical basement of salinization prevention was founded.Also models of "grass industry in salinized areas" and "medical plants industry in salinized areas" are presented,this be sure to lead to obvious ecological,social and ecological efficiency of sustained agriculture in salinized areas in north-west China.%中国西北内陆分布着广袤的盐渍土是影响生态环境和农业可持续发展的一个重要因素.由于盐渍成因多样、盐渍程度强烈、盐分组成复杂、雨水淋盐微弱、表聚作用显著、次生盐渍普遍和单纯用水无法把盐排走等特点,因而相对治理难度比沿海地区更大.作者通过20多年的研究,采用生物防治为主的办法,通过引种盐地先锋植物、应用生物排盐、增大绿色覆盖、防止盐分表聚、培肥地力等措施,使土地能有效地脱盐.同时坚持对植物抗盐机理和盐地资源植物开发利用的研究,使内陆盐渍生物防治建立在理论和应用的基础上.并根据改善西部生态环境,调整种植结

    thousands of individual particles collected in gels in addition to (ii) the sinking particles and SPM present in different particle size fractions on the filters. First results show that the large size fraction carries relatively more intact lipids indicating fresh material being attached to sinking particles rather than suspended in the water column. Furthermore, the distribution of 1G-GDGTs over depths differs from that of 2G- and HPH-GDGTs which might relate to different archaeal communities at different depths. Our findings contribute to the mechanistic understanding of the export of organic molecules through the water column and support the validation of lipid-based paleoceanographic proxies.

    Objective To understand the infection status of intestinal parasites and related knowledge and behavior factors of the residents in north-west Shandong Province,so as to provide the evidence for taking targeted preventive measures. Meth-ods Eighteen villages were randomly selected as survey spots by the stratified multi-stage sample method. The Kato-Katz tech-nique was used to detect intestinal parasite eggs among the residents and the cellophane tape anus test was used to detect Entero-bius vermicularis eggs among 3-12 years old children. Questionnaires were applied to investigate related knowledge and behavior factors about the intestinal parasite infections in the residents. Results Totally 6 366 residents were detected for intestinal para-sites and the infection rate was 0.28%(18 cases). Totally 895 children were detected for E. vermicularis and the infection rate was 5.70%(51 cases). Totally 2 915 residents were investigated by questionnaires and the awareness rate of knowledge about preventing parasitic diseases was 26.72%. The formation rates of washing hands before meal and after WC,washing fruit and vegetable before eating,never drinking unboiled water were 55.42%,42.87%,43.54%and 83.04%respectively. The aware-ness rate of knowledge about preventing parasitic diseases of 3-12 years old children was 12.24%;and the formation rates of washing hands before meal and after WC were 47.04%and 30.44%respectively. Conclusions The total infection rate of intesti-nal parasites is low but the E. vermicularis infection rate is high among children in north-west Shandong Province. The awareness rate of knowledge about preventing parasitic diseases and the formation rates of healthy behaviors are all low. Therefore ,the tar-geted health education should be taken to increase the awareness rate and guide the residents to develop their healthy behaviors.%目的:了解鲁西北地区居民肠道寄生虫感染情况及相关认知状况,为采取有针对性的防治措

    Making use of observation data of GPS in the Northwest China region and infrared distancemeasurements crossing the Qilian-Longshoushan fault zone up to 2004, aided by the least square collocation and inversion of negative dislocation model for the boundaries of elastic blocks and the singular force-source, the dynamic evolution features of deformation and strain fields before and after the Ms = 8. 1 earthquake on the west of Kunlun Mountains Pass,especially the recent tectonic deformation and stress field status three years after this earthquake are studied. The possible regions or segments of active blocks and their boundaries reflecting accumulation background of high strain energy of producing earthquakes over middle magnitude, are obtained, as well as the potential epicenter. The results show that after short-term relaxation and adjustment in the northern margin of Qinghai-Xizang (Tibet) block after the Ms = 8. 1 earthquake, the main control action of background field of northeastward pushing of Indian plate is now recovering. Moreover, the following regions are found to have the background of high strain energy accumulation. They are the middle segment of the northern Tianshan fault zone and its meeting region with the western segment, the middle and western segments of southern Tianshan fault zone and the meeting region with Western Kunlun fault zone, the middle segment of Altun fault, the middle-eastern segment of Qilianshan fault zone and its meeting region with Haiyuan fault, the meeting region of northern margin fault of west Qinling Range and the southeastward expanding line of Zhuanglanghe fault; The Linze and Haiyuan areas also see accumulation of strain energy to some degree.

    2012-12-01

    As part of the US National Climate Assessment, the Northwest region undertook a process of climate risk assessment. This process included an expert evaluation of previously identified impacts, their likelihoods, and consequences, and engaged experts from both academia and natural resource management practice (federal, tribal, state, local, private, and non-profit) in a workshop setting. An important input was a list of 11 risks compiled by state agencies in Oregon and similar adaptation efforts in Washington. By considering jointly the likelihoods, consequences, and adaptive capacity, participants arrived at an approximately ranked list of risks which was further assessed and prioritized through a series of risk scoring exercises to arrive at the top three climate risks facing the Northwest: 1) changes in amount and timing of streamflow related to snowmelt, causing far-reaching ecological and socioeconomic consequences; 2) coastal erosion and inundation, and changing ocean acidity, combined with low adaptive capacity in the coastal zone to create large risks; and 3) the combined effects of wildfire, insect outbreaks, and diseases will cause large areas of forest mortality and long-term transformation of forest landscapes.

  17. Convergence across the northwest Himalaya from GPS measurements

    Science.gov (United States)

    Banerjee, P.; Bürgmann, R.

    2002-07-01

    Horizontal velocities of 26 Global Positioning System (GPS) stations in the northwest Himalayan region provide new constraints on the partitioning of India-Eurasia convergence and elastic strain accumulation about the locked Main Frontal Thrust (MFT). The northwest-striking Karakorum fault slips at 11 +/- 4 mm/yr and contributes to east-west extension of southern Tibet and westward motion of the northwest Himalaya towards Nanga Parbat, rather than playing a role in eastward extrusion of Tibet. Crustal shortening across the Himalaya occurs within a zone centered about 100 km north of the Siwalik Foothills and the MFT. Model inversions of the GPS data indicate that the MFT is locked over a width of ~100 km. Comparison with geologic MFT-slip-rate estimates suggests that this zone is building up a slip deficit at a rate of 14 +/- 1 mm/yr and will eventually fail in future great earthquakes.

    2014-12-01

    This poster describes the results of reconnaissance carried out by the Arctic Institute of North America in summer 2014 in collaboration with USArray and IRIS for deployment of the USArray in northern British Columbia and Yukon Territory, Canada. USArray is a 15-year program to place a dense network of permanent and portable seismographs across the continental United States and parts of Canada. The seismographs record local, regional, and distant (teleseismic) earthquakes. The array records seismic waves that propagate through finer and finer slices of the earth enabling scientists to link structures inherited from earlier stages of continental formation to known and potential geologic hazards (e.g., earthquakes, volcanoes, landslides) (www.usarray.org). USArray deployment in Canada will complement existing Canadian seismic network(s). This project will be particularly significant in the St. Elias region of southwest Yukon, northwest British Columbia, and southeast Alaska as this one of the most seismically active areas and tectonically complex areas in Canada . The deployment will complement ongoing geological mapping carried out by both Yukon Geological Survey, the Geological Survey of Canada and several universities. This reconnaissance work is part of a growing portfolio of research conducted by the Arctic Institute of North America, University of Calgary designed to meet needs for information and enable synthesis and transfer of knowledge for problem solving and decision-making in the north.

    1973-01-01

    A conceptual vehicle and powerplant (10,000-ton) nuclear-powered air-cushion vehicle (ACV) that could open the Northwest Passage and other Arctic passages to commercial traffic is identified. The report contains a description of the conceptual vehicle, including the powerplant and operations, an assessment of technical feasibility, estimates of capital and operating costs, and identification of eligible cargo and markets. A comparison of the nuclear ACV freighter with nuclear container ships shows that for containerized or roll-on/roll-off cargo the ACV would provide greatly reduced transit time between North Atlantic and North Pacific ports at a competitive cost.

The results showed that 86% of patients were males with most common diagnosis in the 5th or 6th decade of the life; 64,5% were working or had had a work related with chronic hand trauma; 16% recognized familiar antecedents; 43,5% had an usual consume of alcoholic drinks; 51% smoked cigarettes; 0% suffered diabetes mellitus 1 and 28,8% diabetes mellitus 2; 1,6% epilepsy; 19% some kind of peripherical vasculopaty; 6.4% some kind of autoimmune disease; 0% degerative neurophaty; 10,3% Tunnel Carpal Syndrome; 32,1% hyperlipemia; 28,8% hyperuricemia; 3,8% liver disease; 77,7% right hand affectation, 70,1% left hand affectation and 47,3% bilateral affectation in the moment of diagnosis, most commonly affected palmar radio were 4th and 5th. Ectopic fibromatoses were an unusual found. As a conclusion, genre, age and clinical findings in our patients seem to be similar to the results presented in North American and north European series. Factors involved in the increase of oxygen free radicals like cigarettes, alcoholic drinks, diabetes melitus, hyperuricemia or peripherical vascular disease, appears in an important amount of our patients with Dupuytren Disease.

    Chemical analyses of organic residues in fragments of pottery from 18 sites in the US Southwest and Mexican Northwest reveal combinations of methylxanthines (caffeine, theobromine, and theophylline) indicative of stimulant drinks, probably concocted using either cacao or holly leaves and twigs. The results cover a time period from around A.D. 750-1400, and a spatial distribution from southern Colorado to northern Chihuahua. As with populations located throughout much of North and South America, groups in the US Southwest and Mexican Northwest likely consumed stimulant drinks in communal, ritual gatherings. The results have implications for economic and social relations among North American populations.

    Aims The objectives of this study were to characterize the C:N:P stoichiometry of the “plant-litter-soil” contin-uum and to better understand nutrient cycling and stability mechanisms in karst forest ecosystems in Southwest China. Methods Three representative forest sites were selected for each of the primary and secondary communities (28 years of natural restoration) in Northwest Guangxi, and measurements were made on carbon (C), nitrogen (N), and phosphorus (P) contents in plants, litter and soils. Important findings Compared with other regions, the plants in karst forest ecosystems had relatively lower C content and higher N content, with a lower C:N ratio in consistency with the characteristics of plants. After 28 years of natural recovery, N and P absorption in secondary forests were at a relatively stable state compared with the primary forest communities. The values of N:P ratio varied from a range of 16–19 in the primary forest communities to 17–19 in the secondary forest communities, without apparent difference in the mean vale between the two contrasting community types. Soil organic C, N and P in karst forests occurred primarily in the top 0–10 cm soil layer, at 92.0 mg·g−1 C, 6.35 mg·g−1 N, and 1.5 mg·g−1 P, respectively. In contrast, the nutrient utilization efficiency and nutrient resorption rate were lower in karst forest plants than in other plant types, with karst forest plants exhibiting a relatively rapid nutrient turnover rate. The N resorption rate was lower, and the P resorption higher, in the primary forest communities than in the secondary forest communities, indicating that the higher N deficiency and lower P deficiency of the primary forest communities compared with the secondary forest commu-nities. Determination of the C:N:P stoichiometric characteristics in the plant-litter-soil continuum in this study provides a scientific guidance for restoration of the vulnerable karst ecosystem in Southwest China.%探明我国西

    The Columbia River has been called the “crown jewel” of the Pacific Northwest. There is no question it is among the region’s greatest assets — supplying low-cost clean hydropower, making deserts bloom thanks to irrigation and providing navigation, recreation and a home for many species of fish and wildlife. The Bonneville Power Administration is proud to be a steward of this great resource. Our mission is to serve the people and environment of the Pacific Northwest. We sell wholesale power from Grand Coulee Dam and 30 other Northwest federal dams to Northwest utilities, including public utility districts, rural electric cooperatives and municipal utility departments, as well as investor-owned utilities. We operate three-fourths of the region’s high voltage transmission system that delivers that power. But, as a federal agency, we are not just a power marketer. We have public responsibilities that include, among many, promoting energy efficiency, facilitating development of renewable power, protecting fish and wildlife affected by hydro development, honoring treaty obligations to tribes and promoting a reliable energy future through collaboration and partnerships. This document describes our responsibilities to citizens in the Pacific Northwest.

    Irradiation of food for disinfestation and preservation is increasing in importance because of increasing restrictions on various chemical treatments. Irradiation treatment is of particular interest in the Northwest because of a growing supply of agricultural products and the need to develop new export markets. Several products have, or could potentially have, significant export markets if stringent insect ocntrol procedures are developed and followed. Due to the recognized potential benefits of irradiation, this program was conducted to evaluate the benefits of using irradiation on Northwest agricultural products. Commodities currently included in the program are cherries, apples, asparagus, spices, hay, and hides.

    The trace element content in rutile was analyzed by both electron microprobe (EMP) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for HP granulite in the Bashiwake area of the South Altun HP-UHP metamorphic belt. Results indicate that Zr content in rutile from HP granulite measured by EMP coincides with these measured by LA-ICP-MS within experimental error. Zr-in-rutile thermometry of Thomkins et aL (2007) yields temperatures that agree with previous results by traditional thermometry calibrations, and thus it is more suitable for temperature estimation for HP granulite in Bashiwake area, whereas the other two calibrations developed by Zack et al. (2004) and Watson et al. (2006) give systematically higher or lower temperatures. Calculated Zr-in-rutile temperatures in fresh HP granulite range from 890 ℃ to 962 ℃ at 2.0 GPa, representing the peak metamorphic temperature of high pressure granulite Zr-in-rutile temperatures in retrogressed HP granulite yielded temperatures between 764 ( and 822 ℃. These results further show that HP granulites in the Bashiwake area of the South Altun HP-UHP metamorphic belt experienced peak conditionis at ultrahigh temperature and high pressure, followed by medium temperature granulite facies conditions related to retrogression.%文中对南阿尔金高压-超高压变质带巴什瓦克地区的高压麻粒岩中的金红石进行了电子探针和薄片原位LA-ICP-MS微量元素分析.教据结果显示,运用电子探针和薄片原位LA-ICP-MS两种实验方法测得巴什瓦克高压麻粒岩中的金红石Zr含量在误差范围内基本一致.对比研究表明,经过压力校正的Thomkins等(2007)的金红石Zr含量温度计算公式更适合本区高压麻粒岩温度的计算,而采用Zack等(2004)和Watson等(2006)的公式计算的温度分别比前人通过传统温度计获得的温度结果偏高和偏低.按照Thomkins等(2007)的金红石Zr含量温度计算公式,以压力为2 GPa

  12. Glacial-to-Holocene evolution of sea surface temperature and surface circulation in the subarctic northwest Pacific and the Western Bering Sea

    It has been proposed that North Pacific sea surface temperature (SST) evolution was intimately linked to North Atlantic climate oscillations during the last glacial-interglacial transition. However, during the early deglaciation and the Last Glacial Maximum, the SST development in the subarctic northwest Pacific and the Bering Sea is poorly constrained as most existing deglacial SST records are based on alkenone paleothermometry, which is limited prior to 15 ka B.P. in the subarctic North Pacific realm. By applying the TEXL86 temperature proxy we obtain glacial-Holocene-SST records for the marginal northwest Pacific and the Western Bering Sea. Our TEXL86-based records and existing alkenone data suggest that during the past 15.5 ka, SSTs in the northwest Pacific and the Western Bering Sea closely followed millennial-scale climate fluctuations known from Greenland ice cores, indicating rapid atmospheric teleconnections with abrupt climate changes in the North Atlantic. Our SST reconstructions indicate that in the Western Bering Sea SSTs drop significantly during Heinrich Stadial 1 (HS1), similar to the known North Atlantic climate history. In contrast, progressively rising SST in the northwest Pacific is different to the North Atlantic climate development during HS1. Similarities between the northwest Pacific SST and climate records from the Gulf of Alaska point to a stronger influence of Alaskan Stream waters connecting the eastern and western basin of the North Pacific during this time. During the Holocene, dissimilar climate trends point to reduced influence of the Alaskan Stream in the northwest Pacific.

    Improvement Districts or ESIDs and what is nationally known as Property Assessed Clean Energy or PACE districts and PACE financing. The project methodology followed the identify, develop, implement, monitor and measure format. These districts began in Toledo and adjoining areas and are expanding to TLCPA’s 28 county financing agency geographic footprint. What began as the Toledo Ohio Advanced Energy Improvement Corporation is now doing business as the Northwest Ohio Advanced Energy Improvement District recognizing it expansion into creating and financing other districts in NW Ohio. The program has been sought out as an advisor by major communities and states in the process of developing similar legislation and programs and has become one of the largest most successful PACE energy improvement and financing districts in the US. The program and the energy district focused on transforming energy use, delivery, conservation and renewable energy as “options of first choice”. The significant energy savings paid for many of the improvements and created a financially viable program well beyond the grant period. The program has become a model within the State of Ohio and Nationally on how to implement and finance projects in broad energy districts including how to evolve and integrate several financing methodologies. It is a unique utilization of revolving loan funds and energy bond pooling with revenue backing primarily from energy improvement special assessments on commercial properties along with some power purchase agreement (PPA) and loan agreement revenue. The program has also incorporated Qualified Energy Conservation Bonds, State of Ohio Energy Loans (SEP), utility rebates, solar and renewable energy certificates, renewable tax incentives and grants, and owner funded equity as additional program leverage and funding. Other keys to this success have been a continual simplification and refinement of the application and documentation process to make funding available easily

  1. The North Atlantic Cold Bias

    2016-04-01

    The North Atlantic cold bias, associated with a too zonal path of the North Atlantic Current and a missing "northwest corner", is a common problem in coupled climate and forecast models. The bias affects the North Atlantic and European climate mean state, variability and predictability. We investigate the use of a flow field correction to adjust the path of the North Atlantic Current as well as additional corrections to the surface heat and freshwater fluxes. Results using the Kiel Climate Model show that the flow field correction allows a northward flow into the northwest corner, largely eliminating the bias below the surface layer. A surface cold bias remains but can be eliminated by additionally correcting the surface freshwater flux, without adjusting the surface heat flux seen by the ocean model. A model version in which only the surface fluxes of heat and freshwater are corrected continues to exhibit the incorrect path of the North Atlantic Current and a strong subsurface bias. Removing the bias impacts the multi-decadal time scale variability in the model and leads to a better representation of the SST pattern associated with the Atlantic Multidecadal Variability than the uncorrected model.

    The geotectonic setting refers to the three-dimensional space and related events based on which a metallogenic system is formed and an ore-forming process takes place. This paper discusses the tectonic evolution of the southwestern margin of the North China paleocontinent and related geotectonic settings in which large or superlarge deposits are formed. Emphasis is put on the geodynamic conditions of the Jinchuan nickel-copper deposit, the Baiyin copper-polymetallic deposit and the Hanshan gold deposit. It is significant that the three deposits occur together as a "trinity" on the same paleocontinental margin. The Jinchuan nickel-copper deposit was formed during the early stage of rifting of the paleocontinental margin; the Baiyin copper-polymetallic deposit was formed during the splitting stage of a continental-margin arc. The continental-margin arc spitting resulted in an "island arc rift" in the early stage of evolution. The Hanshan gold deposit was formed within the Altun sinistral strike-slip fault system and its provenance is the "intraoceanic arc" volcanic rocks.

    Northwest Europe`s offshore operators have boosted their oil and gas production dramatically in recent years, and while the area is now mature, a steady stream of developments continues. In the boom days of the late 1970s and 1980s, a typical North Sea installation was a large platform, which occasionally a new pipeline or, more commonly, a tie-in to the area`s massive export grids. These days, now that technical developments have enabled operators to justify developments of smaller, once uneconomic, discoveries, it is pointless to talk of a typical offshore development. Northwest Europe`s offshore operators have learned that it is worthwhile to rack their brains for the most economic development concepts. This creativity is reflected in recent development plans. While operators are now snatching up the small accumulations in and around the mature North Sea producing fields, they are also seeking develop frontier regions. The paper discusses development activities in UK, Ireland, Denmark and Greenland, and Norway in gas, oil, and gas condensate deposits.

    The U.S. Department of Energy (DOE) Pacific Northwest Site Office (PNSO) oversees and manages the DOE contract for the Pacific Northwest National Laboratory (PNNL), a DOE Office of Science multi-program laboratory located in Richland, Washington. PNSO is responsible for ensuring that all activities conducted on the PNNL Site comply with applicable laws, policies, and DOE orders. The DOE Pacific Northwest Site Office Cultural and Biological Resources Management Plan (DOE/PNSO 2008) addresses the requirement for annual surveys and monitoring for species of concern and to identify and map invasive species. In addition to the requirement for an annual survey, proposed project activities must be reviewed to assess any potential environmental consequences of conducting the project. The assessment process requires a thorough understanding of the resources present, the potential impacts of a proposed action to those resources, and the ultimate consequences of those actions. The PNNL Site is situated on the southeastern corner of the DOE Hanford Site, located at the north end of the city of Richland in south-central Washington. The site is bordered on the east by the Columbia River, on the west by Stevens Drive, and on the north by the Hanford Site 300 Area (Figure 1). The environmental setting of the PNNL Site is described in Larson and Downs (2009). There are currently two facilities on the PNNL Site: the William R. Wiley Environmental Molecular Sciences Laboratory (EMSL), and the recently completed Physical Sciences Facility (PSF). This report describes the results of the annual survey of the biological resources found on the undeveloped portions of the PNNL Site in 2010. A brief description of the methods PNNL ecologists used to conduct the surveys and the results of the surveys are presented. Actions taken to fully delineate noxious weed populations discovered in 2009 and efforts in 2010 to control those weeds also are described. Appendix A provides a list of plant and

    Northwest Africa defined here as the area including Morocco, Algeria and Tunisia, occupies a large territory in North Africa with an area exceeding 3.5 million km2. The geographical contrast is very important: while most of the southern part is desert, the northern and northwestern parts exhibit a contrasting geography including large flat areas in the western part of Morocco, northern Algeria and eastern part of Tunisia and the formidable Atlas mountains barrier extends from south west of Morocco toward north west of Tunisia crossing central Morocco and north Algeria. Agriculture is one of major socio-economic activities in the region with an extensive cash-crop for exporting to Europe especially from Morocco and Tunisia. The influence of the recurring droughts during the 80s and 90s was very crucial for the economic and societal aspects of the region. In Morocco, severe droughts have caused GDP fluctuation within past 20 years from 10% increase down to negative values in some particular years. Recent studies have investigated seasonal rainfall variability and prediction over MOROCCO in the framework of regional and international collaboration. Results from this work has shown that the main general circulation feature associated with the rainfall variability within Morocco is the North Atlantic Oscillation. The relationship is in fact due to the major role played by the AZORES high pressure with its role in modulating the main position of the active synoptic systems in the north Atlantic area and therefore in modulating the frequency and the intensity of the weather systems that impact the western part of the region. Mediterranean sea plays also major role in the mid of the region. In this paper we applied EOF technique on 500 hPa. The data used are monthly reanalysis NCEP/NCAR analyses for November from 1960 to 1990 climatological time series. Correlation analysis is then performed between EOF time series and global 4x4 degre SST anomalies. The results we

    The Pacific NorthWest Economic Region, a statutory organization chartered by the Northwest states of Alaska, Washington, Idaho, Montana, and Oregon, and the western Canadian provinces of British Columbia, Alberta, and the Yukon through its Energy Working Group launched a bi-national energy planning initiative designed to create a Pacific Northwest energy planning council of regional public/private stakeholders from both Canada and the US. There is an urgent need to deal with the comprehensive energy picture now before our hoped for economic recovery results in energy price spikes which are likely to happen because the current supply will not meet predicted demand. Also recent events of August 14th have shown that our bi-national energy grid system is intricately interdependent, and additional planning for future capacity is desperately needed.

  11. Metamorphism history and dynamics of high-pressure granulites in the Dulan area of the North Qaidam Mountains, northwest China%柴北缘都兰高压麻粒岩的变质演化及形成的动力学背景

    A high-pressure granulite unit was recognized in the Dulan area, the eastern end of the North Qaidam-South Altyn HP-UHP metamorphism belt, Northwest China. High-pressure granulites are mainly mafic in composition although small amounts of acid-intermediate varieties also exist. Mineral assemblages in equilibrium in mafic granulites contain mainly garnet, clinopyroxene, plagioclase, with different amounts of kyanite, amphibole, rutile, quartz, zoisite/clinozoisite, scapolite and ilmenite, whereas acid-intermediate granulites contain garnet, kyanite, K-feldspar, plagioclase and quartz, with small amounts of clinopyroxene and amphibole. Petrologic and mineralogical data indicate these HP rocks experienced multistage metamorphism history. Thermobarometry of the peak mineral assemblages yields P-T conditions of 1.40 ~ 1. 85GPa and 800 ~ 925℃ . Retrogression began under high amphibolite-facies conditions estimated at 0. 8 ~ 1. 05GPa and 580 ~ 695℃ , and is followed by subsequent retrogression under low amphibolite-facies/greenschist-facies conditions ( <0. 8GPa and < 550℃ ). This study suggests that the Dulan high-pressure granulites experienced a single metamorphic history, and not associated with the effects of thermal relaxation after eclogite-facies metamorphism recorded in adjacent eclogites. The high-pressure granulites probably formed at the bottom of thickening continental crust related to continental subduction corresponding to the depth of about 50 ~ 70 km.%在柴北缘-阿尔金HP/UHP变质带东端,新识别出一个高压麻粒岩单元.高压基性麻粒岩是高压麻粒岩单元的主体,还包括少量高压中酸性麻粒岩.高压基性麻粒岩主要由平衡共生的石榴子石、单斜辉石、斜长石组成,还含有不等量的蓝晶石、角闪石、石英、金红石、黝帘石/斜黝帘石、钛铁矿、方柱石等矿物.高压长英质麻粒岩主要包括石榴子石、蓝晶石、钾长石、斜长石

    Kinematic, geodetic, and geologic observations define a region with 6-8 mm/y of north-south contraction between the Columbia River and Vancouver Island. We attribute this contraction to differential forearc-block motion within the Cascadia subduction system where the Oregon Coast Range block is moving northward relative to Vancouver Island. The contraction is accommodated by a combination of distributed uplift in the Olympic Mountains, and faulting along the margins of the Coast Range and Vancouver Island blocks. The tide gauge at Neah Bay, which records one of the highest rates of uplift anywhere along the Cascadia subduction margin, suggests that a significant portion of this north-south contraction occurs between the northern Olympic Peninsula and Vancouver Island. The northwest-trending Calawah fault, extending from Makah Bay eastward to near Lake Crescent, appears to mark the modern boundary between the Olympic Mountains block and the Vancouver Island block in northwestern Washington. Onshore, the 80+ km-long Calawah fault displaces late Quaternary glacial sediments and geodetic uplift rates increase abruptly across the fault zone. Offshore in Makah Bay, new multibeam, sidescan-sonar, and high-resolution seismic reflection data image a complex, multi-strand fault zone that offsets the seafloor and moves Cape Flattery rocks seaward. Two parallel, northwest-trending fault strands bound a down-dropped block that in turn terminates along a northward-trending anticlinal fold and thrust fault. These data suggest that the Calawah fault zone currently accommodates contraction both by uplift and by seaward translation of rocks north of the forearc-block boundary. Our geologic mapping in the Cape Flattery area indicates that differential block motion is accommodated by a combination of crustal uplift, folding, and left-lateral, strike-slip faulting.

    The North Atlantic Oscillation is the dominant atmospheric pressure mode in the North Atlantic region and affects winter temperature and precipitation in the Mediterranean, northwest Europe, Greenland, and Asia. The index that describes the sea-level pressure difference between Iceland and the Azores is correlated with a dipole precipitation pattern over northwest Europe and northwest Africa. How the North Atlantic Oscillation will develop as the Greenland ice sheet melts is unclear. A potential past analogue is the early Holocene, during which melting ice sheets around the North Atlantic freshened surface waters, affecting the strength of the meridional overturning circulation. Here we present a Holocene rainfall record from northwest Africa based on speleothem δ18O and compare it against a speleothem-based rainfall record from Europe. The two records are positively correlated during the early Holocene, followed by a shift to an anti-correlation, similar to the modern record, during the mid-Holocene. On the basis of our simulations with an Earth system model, we suggest the shift to the anti-correlation reflects a large-scale atmospheric and oceanic reorganization in response to the demise of the Laurentide ice sheet and a strong reduction of meltwater flux to the North Atlantic, pointing to a potential sensitivity of the North Atlantic Oscillation to the melting of ice sheets.

    a été mise en place.Madagascar is one of the most important hotspot of the world biodiversity. Among the numerous endemic animals living in the island, the lemurs are the more emblematic. Within the primate order, this group is one of the most diversified. If their origin is still not clear, numerous extinct subfossils species have been recorded for at least 26 000 years, the more recent ones being only a few hundred years old. The lemurs are mentioned in ancient texts or legends because of their size which made an impression on people. The causes of their extinction remain poorly known. Historically, the majority of the subfossil sites were known in two geographical areas: the South-West and the Center of Madagascar, which shared a few species. More recently, some subfossils have been discovered in the North of the island, but almost nothing was known in the North-West of Madagascar until 1997 when explorations were undertaken in the framework of a collaboration between malagasy and french researchers.Currently, 19 sites are known and many subfossils were discovered. A new species of extinct lemur was described, Palaeopropithecus kelyus. Numerous non-lemur taxa are recorded (micro-and macrofauna and contribute to understand the history of the past biodiversity and palaeoenvironments.This fair collaboration is also a human adventure. The different participants of the two countries take an equal part in the fieldwork, the studies, the technical and academic training of the students at the University of Mahajanga, and the popularization of the results. Through exhibitions the new Malagasy generations are sensitized to the preservation of their geological and natural heritage.

    Russia owns the largest natural gas, the second largest coal and the third largest oil reserves in the world. Russia is the third largest energy user and the largest producer of oil and gas in the world. Export of oil and gas plays a major role in the economic development of the whole Russia. Wood harvesting and processing industry responds only 4,4 % of the industrial production although Russia owns 23 % of the world's forest resources. Biomass represents only 1 % of the total energy consumption including residential use but hydro power represents about 18 % of Russia's electricity generation. Russia needs three times more energy to produce one unit of GDP than e.g. EU. This indicates very poor energy efficiency and poor conditions of the energy and the whole infrastructure as well. Simultaneously the prices of fossil fuels and electricity are heavily subsidized. These basic figures give on idea why utilization of renewable energy and especially biomass play a minor role in Russian energy system. One of the most progressive regions in bioenergy is the Northwest of Russia. The first pellet and briquette plants were installed in this region a few years ago. The region can be regarded as the forerunner in bioenergy in Russia. Federal Region of Northwest Russia consists of City of St.Petersburg, Republics of Karelia and Komi and regions of Leningrad, Arkhangelsk, Kaliningrad, Murmansk, Nenetsk, Novgorod, Pskov and Vologda. The region has 15 million inhabitants and a 2200 km long joint border with the EU, most of that with Finland. N W Russia owns over 14000 million m3 of raw wood that represents 17 % of Russian forests and 60 % of the forests located in the European side. Potential for annual harvesting is over 100 million m3 while harvesting is about 45 million m3. Most of that is exported as a form of raw wood. Wood represents only 2,8 % of the region's energy use including residential usage. Use of peat is marginal representing only 0,1 % of the

    The existence of intra-plate deformation of the Sundaland platelet along its eastern edge in North Borneo, South-East Asia, makes it an interesting area that still is relatively understudied. In addition, the motion of the coastal area of North-West Borneo is directed toward a frontal fold-and-thrust belt and has been fueling a long debate on the possible geophysical sources behind it. At present this fold-and-thrust belt is not generating significant seismic activity and may also not be entirely active due to a decreasing shelfal extension from south to north. Two sets of Global Positioning System (GPS) data have been used in this study; the first covering a time period from 1999 until 2004 (ending just before the Giant Sumatra-Andaman earthquake) to determine the continuous Sundaland tectonic plate motion, and the second from 2009 until 2011 to investigate the current deformations of North Borneo. Both absolute and relative positioning methods were carried out to investigate horizontal and vertical displacements. Analysis of the GPS results indicates a clear trend of extension along coastal regions of Sarawak and Brunei in North Borneo. On the contrary strain rate tensors in Sabah reveal that only insignificant and inconsistent extension and compression occurs throughout North-West Borneo. Moreover, station velocities and rotation rate tensors on the northern part of North Borneo suggest a clockwise (micro-block) rotation. The first analysis of vertical displacements recorded by GPS in North-West Borneo points to low subsidence rates along the western coastal regions of Sabah and inconsistent trends between the Crocker and Trusmadi mountain ranges. These results have not been able to either confirm or reject the hypothesis that gravity sliding is the main driving force behind the local motions in North Borneo. The ongoing Sundaland-Philippine Sea plate convergence may also still play an active role in the present-day deformation (crustal shortening) in North

    The U.S. Department of Energy (DOE) Pacific Northwest Site Office (PNSO) oversees and manages the DOE contract for the Pacific Northwest National Laboratory (PNNL), a DOE Office of Science multi-program laboratory located in Richland, Washington. PNSO is responsible for ensuring that all activities conducted on the PNNL site comply with applicable laws, policies, and DOE Orders. The DOE Pacific Northwest Site Office Cultural and Biological Resources Management Plan (DOE/PNSO 2008) addresses the requirement for annual surveys and monitoring for species of concern and to identify and map invasive species. In addition to the requirement for an annual survey, proposed project activities must be reviewed to assess any potential environmental consequences of conducting the project. The assessment process requires a thorough understanding of the resources present, the potential impacts of a proposed action to those resources, and the ultimate consequences of those actions. The PNNL site is situated on the southeastern corner of the DOE Hanford Site, located at the north end of the city of Richland in south-central Washington. The site is bordered on the east by the Columbia River, on the west by Stevens Drive, and on the north by the Hanford Site 300 Area (Figure 1). The environmental setting of the PNNL site is described in Larson and Downs (2009). There are currently two facilities on the PNNL site: the William R. Wiley Environmental Molecular Sciences Laboratory and the Physical Sciences Facility. This report describes the annual survey of biological resources found on the undeveloped upland portions of the PNNL site. The annual survey is comprised of a series of individual field surveys conducted on various days in late May and throughout June 2011. A brief description of the methods PNNL ecologists used to conduct the baseline surveys and a summary of the results of the surveys are presented.

    wedge formation, the subhorizontal ductile extension and crustal thinning as well as the top-to-the north shearing along the high-angle ductile shear zones responsible for exhumation of the HP unit as a coherent slab, are consistent with those recognized in the Dabie-Sulu UHP and HP metamorphic belts, suggesting that they were closely associated in time and space. The Xiongdian-Suhe HP metamorphic unit thus forms part of the Triassic (250-230 Ma) collision orogenic belt, and can not connect with the South Altun-North Qaidam-North Qinling UHP metamorphic belt formed during the Early Paleozoic (500-400 Ma).

    In 2015, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) program is assessing stream quality in the Pacific Northwest. The goals of the Pacific Northwest Stream Quality Assessment (Pacific Northwest study) are to assess the quality of streams in the region by characterizing multiple water-quality factors that are stressors to aquatic life and to evaluate the relation between these stressors and biological communities. The effects of urbanization and agriculture on stream quality for the Puget Lowlands and Willamette Valley are the focus of this regional study. Findings will provide the public and policymakers with information regarding which human and environmental factors are the most critical in affecting stream quality and, thus, provide insights about possible approaches to protect or improve the health of streams in the region.

    Phosphorus is a naturally occurring element found in all rocks; the amount varies by the type of rock. The amount of phosphorus in sediments is expected to be correlated with the amount of phosphorus in the parent rocks. Streambed sediment collected by the National Uranium Resource Evaluation (NURE) Program were used to estimate the variation of phosphorus across the Pacific Northwest. This file provides an estimate of the mean concentration of phosphorus in soils for each incremental catchment of the USGS Pacific Northwest SPARROW model.

    Full Text Available This article examines the practice of piercing and stretching the lip in order to accommodate a labret in two regions: the North American Northwest Coast (with historical examples from Tlingit and Haida groups and lowland South America (utilizing ethnographic writings on Suya and Kayapo communities. Drawing on the recent ‘sensorial turn’ within anthropology, I suggest an approach which goes beyond considerations of the symbolism of body ornaments and analyses how the infliction of pain they involve can be manipulated to serve social ends at a local level. Also discussed is the use of labrets within global ‘mediascapes’ (Appadurai 1996 by Kayapo and Northwest Coast groups in the context of self-representation and the politicization of ‘culture’ (Wright 1998.

  9. Contemporary vertical crustal motion in the Pacific Northwest

    Science.gov (United States)

    Holdahl, Sandford R.; Faucher, Francois; Dragert, Herb

    A map of recent vertical crustal motion has been compiled for coastal Washington and southwest British Columbia. Average velocities over the past 80 years were determined by least squares adjustment of repeated precise levelings and mean sea-level observations from 21 tide gauges. Annual variations in mean sea level were determined directly within the adjustment model under the assumption that they were identical at all tide gauges in a given year. The derived vertical velocities range from -2.0±0.9 mm/yr near Seattle, to 2.5±0.8 mm/yr at the northwest tip of the Olympic Peninsula, and over 3 mm/yr in the region to the north of Campbell River on Vancouver Island. Determination of a constant velocity in this latter region is complicated by about 10 cm of coseismic subsidence associated with a magnitude 7.3 earthquake in 1946, and an apparent increase in uplift rate over the past decade. Qualitatively, the regional velocity pattern is consistent with features of the current plate convergence model: 1) the rapid uplift of the region north of central Vancouver Island is consistent with the overriding of the young (Explorer Plate which may be underplating the coastal margin in this area; and 2) the ridge of uplift extending from the Neah Bay area north across Vancouver Island to Campbell River is consistent with a pattern expected from a locked subduction zone underlying this coastal region. The large-scale subsidence to the southwest of Puget Sound is more difficult to explain in the context of plate convergence.

    Radioiodine, {sup 129}I is a biophilic and mobile radionuclide, and a major contaminant of concern for long term radioactive waste disposal. Nuclear fuel reprocessing has released large amounts of anthropogenic {sup 129}I in a number of locations globally; this has led to an increase in the concentration of {sup 129}I and the {sup 129}I/{sup 127}I ratio in the environment. Therefore, a detailed understanding of its movement and concentration in the environment is essential. While {sup 129}I dispersion has been examined in the vicinity of nuclear activities, little is known about its accumulation in remote regions. Accordingly, we have undertaken reconnaissance sampling in the Arctic as a location that may be affected by {sup 129}I fallout. Samples from large watersheds were collected in northern Canada on a trajectory starting in Whitehorse, Yukon Territory (60 Degree-Sign 43 Prime 00 Double-Prime N) and moving north to Tsiigehtchic, Northwest Territory (67 Degree-Sign 26 Prime 26 Double-Prime N). Results show concentrations of {sup 129}I up to 27 Multiplication-Sign 10{sup 6} atoms/L are present in Northwest Canada and {sup 129}I/I ratios up to 1.68 Multiplication-Sign 10{sup -10}. Annual {sup 129}I fallout ranges from 2.78 Multiplication-Sign 10{sup 9} to 7.95 Multiplication-Sign 10{sup 9} atoms/m{sup 2}/yr, calculated by normalizing the measured values to watershed area and discharge. These quantities substantially exceed literature values for waters containing only geogenic or cosmogenic production and are similar for all watersheds regardless of watershed area or discharge. Anthropogenic releases of {sup 129}I into the atmosphere or oceans are the major potential sources of {sup 129}I in the Arctic.

    Columbia River System Operation Review (U.S.)

    1995-11-01

    Currently, the Federal government coordinates the planning and operation of the Federal Columbia River Power System (FCRPS) with projects owned and operated by the region`s non-Federal hydrogenerating utilities pursuant to the Pacific North-west Coordination Agreement (PNCA). The Bureau of Reclamation (Reclamation), the Corps of Engineers (Corps), and the Bonneville Power Administration (BPA) are parties to the PNCA on behalf of the government of the United States. The PNCA is a complex agreement that provides an opportunity for the region`s power producers to maximize the power system`s reliability and economy while meeting their multiple-use objectives. The PNCA does not dictate the operation of the resources it coordinates. It is essentially an accounting mechanism that exchanges the power produced among the parties in order to improve the reliability of the system and reduce regional power costs. Project owners retain complete autonomy to operate as needed to meet their multiple-use requirements. The PNCA was executed in 1964 as an important component of regional plans to maximize the Northwest`s hydro resource capability. Maximization also included the development of storage projects on the Columbia River in Canada pursuant to the terms of the 1964 Columbia River Treaty. Because of the link between power coordination and Treaty issues, the current parties to the PNCA, currently are contemplating entering into a replacement or renewed power coordination agreement. Because the power coordination agreement is a consensual arrangement, its ultimate provisions must be acceptable to all of its signatories. This Appendix R to the Final Environmental Impact Statement of the Columbia River System is a presentation of the Pacific North-west Coordination Agreement.

    Prinz, Rainer; Abermann, Jakob; Steiner, Jakob

    2017-04-01

    Land-terminating ice cliffs are intriguing features that occur in various ice-covered regions around the world both in high and low latitudes. Over flat terrain land-terminating ice cliffs can only persist under a complex interplay between certain climatic and ice dynamic conditions with "cold" and "dry" being the common pillars for their occurrence. In North Greenland, dry calving ice cliffs are an abundant feature, however, to our knowledge, detailed investigations are limited to studies more than six decades ago in the Thule area. Rough estimates state that approximately 45% of the ice sheet in Northwest Greenland terminate as cliffs on land. The ice cliff position and its change with time is a combined signal of the ice flow and mass balance at the cliff. The ice flow is triggered by a mass imbalance upstream the ice cliff integrating a potentially long response time, basal sliding and ice deformation, whereas the mass balance of the ice cliff is determined by the sum of the energy fluxes at the cliff face and the calving flux. Studies during the 1950s and 1960s report counterintuitive results with a generally negative mass balance and a reduction of ice cliff height versus a net advance of the cliff. This intriguing evolvement warrants closer attention as it remained unstudied thereafter even though it is likely relevant for a large portion of cold and dry North Greenland. Thus, the purpose of this contribution is to build a relevant basis for future process studies by (i) determining the occurrence of ice cliffs in Northern Greenland, (ii) classifying them by obvious morphological distinctions such as height and steepness and (iii) give a first-order estimate on percentage of advancing vs retreating areas. Repeating the past study above using recent space-borne earth observation data (digital elevation models from 1985, 2007 and 2015) we mapped the evolution of the ice sheet margin.

    2006-12-15

    Severe wind and snow storms hit the Pacific Northwest region on December 14 – 15, 2006, following severe flooding during the past few days. The severe weather resulted in major power outages through the region. At peak there were 1.8 million customers without power which included BC Hydro in Canada. Currently, there are over 1.5 million outages in the region as a result of the Pacific Northwest Storms. This represents about 42 percent of customers in affected utility service areas in Oregon and Washington. See table below. Because the current wind and snow storms are coming on the heels of extensive flooding in the region, electric utilities are experiencing damage. Wind gusts reached close to 100 mph in some areas of the region. The storm is expected to bring its strong winds and heavy snow into Idaho, Montana and Wyoming Friday and into the weekend. There are currently no reported major impacts to the petroleum and natural gas infrastructure.

    These Discussion Papers are from a number of organizations with a high stake in the future performance of the Bonneville Power Administration. Bonneville solicited papers from other organizations to assure a broaded-based discussion of the topics for the 1991 Programs in Perspective. PIP meetings will be held throughout the Northwest in September. PIP runs on a two-year cycle. The first year is aimed at discussion of broad, strategic issues. The second year evaluates specific program levels for all Bonneville programs and test them for affordability against financial constraints. This year's PIP focuses on strategic-issues discussion. It specifically asks for regional discussion to help put some flesh on the skeleton of Bonneville's own vision for its future: Best for the Northwest Through Teamwork B... P... A... The Most Competitive and Socially Responsible Power System in the Nation'' Specific topics are (1) achieving social responsibility and (2) conserving Northwest competitiveness. Bonneville executives chose this vision as a means of directing the organization into and beyond the 1990s. It guides the 3000 plus employees of the agency in their day-to-day operations. By asking for discussion of the terms Most Competitive'' and Socially Responsible'' in the 1991 PIP, Bonneville intends to better understand the diverse needs of its customers and constituents, and to become of even greater service to the Northwest. The papers are designed to help stimulate thought about the dimensions of the future direction of BPA. Bonneville intends that the real substance of PIP will occur in the meetings themselves. We hope that these papers will provoke new thinking, and that the interchange of views in the meetings will produce new approaches to the issues.

    2008-01-01

    Rivers and streams that drain from Olympic, Mount Rainier, and North Cascades National Parks are among the most protected corridors in the lower 48 States, and represent some of the largest tracts of contiguous, undisturbed habitat throughout the range of several key fish species of the Pacific Northwest. These watersheds are of high regional importance as freshwater habitat sanctuaries for native fish, where habitat conditions are characterized as having little to no disturbance from development, channelization, impervious surfaces, roads, diversions, or hydroelectric projects. Fishery resources are of high ecological and cultural importance in Pacific Northwest National Parks, and significantly contribute to economically important recreational, commercial, and tribal fisheries. This protocol describes procedures to monitor trends in fish assemblages, fish abundance, and water temperature in eight rivers and five wadeable streams in Olympic National Park during summer months, and is based on 4 years of field testing. Fish assemblages link freshwater, marine, and terrestrial ecosystems. They also serve as focal resources of national parks and are excellent indicators of ecological conditions of rivers and streams. Despite the vital importance of native anadromous and resident fish populations, there is no existing monitoring program for fish assemblages in the North Coast and Cascades Network. Specific monitoring objectives of this protocol are to determine seasonal and annual trends in: (1) fish species composition, (2) timing of migration of adult fish, (3) relative abundance, (4) age and size structure, (5) extent of non-native and hatchery fish, and (6) water temperature. To detect seasonal and annual trends in fish assemblages in reference sites, we rely on repeated and consistent annual sampling at each monitoring site. The general rationale for the repeated sampling of reference sites is to ensure that we account for the high interannual variability in fish

  11. Foreland normal fault control on northwest Himalayan thrust front development

    1998-10-01

    In the Trans-Indus Ranges along the western part of the northwest Himalayan thrust front, unconformities, changes in paleocurrent directions, and locally derived conglomerates in synorogenic foreland basin deposits provide evidence for major local deformation at ≥3.5 Ma. The tectonic history of the Trans-Indus Ranges has previously been described in terms of a single episode of major thrusting at ≤1 Ma, thus our work implies that there were two distinct phases of deformation. In conjunction with published evidence in the Salt Range to the east for two phases of deformation (˜6 to 5 Ma, and ˜2.5 Ma to present), this study demonstrates that these two phases of deformation are regionally significant and probably correlative along the entire present-day NW Himalayan thrust front. Reconstruction of possible source areas for the locally derived conglomerates shows that the earlier deformation is probably related to normal faulting. These results suggest that the tectonic evolution of the area along the present-day thrust front is characterized by (1) latest Miocene to early Pliocene formation of north dipping normal fault zones (total throw ≥ 600 m) within the foreland basin, related to syn-orogenic flexure of the Indian plate, and (2) late Pliocene to early Pleistocene initiation of south directed thrusting along the present-day thrust front, related to outward growth of the NW Himalayan thrust wedge. The location of the present-day thrust front appears to be controlled by north dipping normal faults and monoclines that formed during the earlier deformation and subsequently localized structural ramps during later thrusting.

    According to current literature a large region encompassing nearly the entire west half of the U.S. belongs to one dialect region referred to as Western, which furthermore, according to Labov et al., ``... has developed a characteristic but not unique phonology.'' [http://www.ling.upenn.edu/phono-atlas/NationalMap/NationalMap.html] This paper will describe the vowel space of a set of Pacific Northwest American English speakers native to the Ballard neighborhood of Seattle, Wash. based on the acoustical analysis of high-quality Marantz CDR 300 recordings. Characteristics, such as low back merger and [u] fronting will be compared to findings by other studies. It is hoped that these recordings will contribute to a growing number of corpora of North American English dialects. All participants were born in Seattle and began their residence in Ballard between ages 0-8. They were recorded in two styles of speech: individually reading repetitions of a word list containing one token each of 10 vowels within carrier phrases, and in casual conversation for 40 min with a partner matched in age, gender, and social mobility. The goal was to create a compatible data set for comparison with current acoustic studies. F1 and F2 and vowel duration from LPC spectral analysis will be presented.

    2015-01-01

    Winter coastal upwelling off northwest Borneo in the South China Sea (SCS) is investigated by using satellite data, climatological temperature and salinity fields and reanalysis data. The upwelling forms in Decem-ber, matures in January, starts to decay in February and almost disappears in March. Both Ekman trans-port induced by the alongshore winter monsoon and Ekman pumping due to orographic wind stress curl are favorable for the upwelling. Transport estimates demonstrate that the month-to-month variability of Ekman transport and Ekman pumping are both consistent with that of winter coastal upwelling, but Ek-man transport is two times larger than Ekman pumping in January and February. Under the influence of El Niño-Southern Oscillation (ENSO), the upwelling shows remarkable interannual variability: during winter of El Niño (La Niña) years, an anticyclonic (a cyclonic) wind anomaly is established in the SCS, which behaves a northeasterly (southwesterly) anomaly and a positive (negative) wind stress curl anomaly off the north-west Borneo coast, enhancing (reducing) the upwelling and causing anomalous surface cooling (warming) and higher (lower) chlorophyll concentration. The sea surface temperature anomaly (SSTA) associated with ENSO off the northwest Borneo coast has an opposite phase to that off southeast Vietnam, resulting in a SSTA seesaw pattern in the southern SCS in winter.

  14. Heat flow in northwest Pacific marginal seas

    Heat flow studies in Northwest Pacific marginal seas has a more than 40 years history with more than 4000 heat flow values obtained. The regional average value is 80.4 mW/m2, which is lower than the world's 87 mW/m2, but higher than those of the Eurasia continent and the Pacific Ocean. This reflects the regional crust property in the area. The studies on distribution of the heat flow and contour pattern of heat flow in 1°×1°and 2°×2°scales in Northwest Pacific marginal seas revealed that the most high heat flow anomalies in the area were found along back-arc basins and island arc in an obviously northeasterly track. Exceptions are the Komandoskaya Basin (KMB), the Izu-Bonin Trough (IBT) and the Mariana Trough (MT), which extend in northwest. The contours of low heat flow marked the boundaries of the continent and the ocean. The present heat flow values reflect the imprint of the last thermal event and relate closely to tectonic activity. The high heat flow gradient areas have high frequency of earthquake. Therefore, the area of faulting controlled the pattern of the heat flow anomalies. Heat flow gradient in 135°direction indicated a major lithosphere transformation oceanward resulting from movement of the earth's material. In this paper, we described patterns of heat flow distribution in the Northwest Pacific, heat flow value changes in horizontal and vertical directions, combining the studies of Shi (1997) on the landforms of the island arcs in east Asia and plate movement, and the results of Shi and Zhang (1998) on heat simulation of subduction of active ocean mountain and the activity of islands arc. A preliminary model of geodynamics in the Northwest Pacific and its adjacent area was put forward. There is a great lateral heat flow gradient on the surface of the mantle between ocean and continent, which indicates that the materials in asthenosphere move from continent to ocean causing movement of the crust.

    Primary biliary cirrhosis (PBC) is a well-known but uncommon chronic liver disease that is presumed to be of autoimmune etiology. Recently, investigations in British Columbia (BC), a province of Canada situated along the Pacific North-West of North America, have suggested that PBC is not a rare disease amongst BC's Aboriginal (i.e. First Nations) communities. Geographically, BC is adjacent to South East Alaska, an American state that has also reported an increased prevalence of PBC amongst its Aboriginal communities. In this article, the medical evidence supporting a hypothesis of increased risk of PBC amongst BC's First Nations communities is reviewed. Evidence suggesting that autoimmune hepatitis is also more likely amongst BC's First Nations communities is also presented.(C)2006 The WJG Press. All rights reserved.

    The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to its regional power sales contracts. Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book will not be used in calculations for the 2002 regional power sales contract subscription process. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for determining BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. In this loads and resources study, resource availability is compared with a medium forecast of electricity consumption. The forecasted future electricity demands--firm loads--are subtracted from the projected capability of existing and ''contracted for'' resources to determine whether BPA and the region will be surplus or deficit. If Federal system resources are greater than loads in any particular year or month, there is

    Well S provides a good opportunity to investigate the petroleum filling history in Tazhong North Slope. Petrographic investigations suggest that bitumen, oil, and petroleum inclusions coexist in Silurian sandstones from well S, reflecting a complicated reservoir filling history in the study area. Integration of organic geochemistry and fluid inclusion analysis shows that the Silurian reservoir has experienced three episodes of petroleum charge, that is from the late Silurian to the early Devonian, the early-middle Triassic and the Paleogene, respectively. The present-day reservoir fluids in the Silurian are the mixtures generated in multiple (at least two) episodes of petroleum charge. The oil charging into Silurian resevior in the early period had experienced considerable degradation, and was mixed with later non-degraded oil.

    In the late nineteenth century Franz Boas was responsible for assembling anthropometric data from North Amerindians. Approximately 15,000 subjects were measured, but the data have never been systematically analyzed. Here we describe our efforts to develop a computerized database from Boas's data and present the first systematic analysis of these data. In addition to a general analysis of North Amerindian anthropometric variation, we also present a more detailed analysis of anthropometric variation among tribes located in the American Northwest. In the general analysis we find that anthropometric variation is strongly patterned along geographic lines. We examine geographic and language patterning by grouping tribes by culture area and language phylum. Both have high explanatory power, culture area being the higher. The Northwest analysis shows that both language and geographic location are important in explaining anthropometric variation.

  8. Paleomagnetism of the Tertiary Clarno Formation of central Oregon and its significance for the tectonic history of the Pacific Northwest

    1986-12-01

    The Clarno Formation, a mostly Eocene and partly early Oligocene sequence of andesitic lavas and volcaniclastic rocks, is the oldest Tertiary formation exposed in north central Oregon. Remanent magnetization directions at 46 sites in the lavas provide a paleomagnetic pole at 84°N, 278°E with a 95% confidence cone of 7°. Comparison of this pole with the North American reference pole for Eocene time indicates that the Clarno Formation has rotated 16° clockwise with an uncertainty of 10° but has undergone no significant latitudinal displacement. Further comparison with paleomagnetic data from the Miocene Columbia River Basalt Group and Steens Basalt shows that large-scale block rotations in the eastern Columbia Embayment ceased sometime between 38 m.y. and 15 m.y. A paleogeographic reconstruction for 38 m.y. is offered which is consistent with the observed rotation of the Clarno and with the other paleomagnetic data from the Pacific Northwest, which are briefly reviewed. This reconstruction shows that it is possible to account for virtually all of the paleomagnetically indicated rotations in pre-Miocene Tertiary rocks of the Pacific Northwest by an extensional tectonic model. As a consequence, only part of the rotations in the pre-Tertiary rocks of the eastern Columbia Embayment need to be the result of accretionary tectonics. The initiation of magmatism in the eastern Columbia Embayment that is represented by the Clarno Formation itself may have been contemporaneous with the beginning of crustal extension in the Pacific Northwest.

    The main objective of the Northwest Clean Energy Application Center (NW CEAC) is to promote and support implementation of clean energy technologies. These technologies include combined heat and power (CHP), district energy, waste heat recovery with a primary focus on waste heat to power, and other related clean energy systems such as stationary fuel cell CHP systems. The northwest states include AK, ID, MT, OR, and WA. The key aim/outcome of the Center is to promote and support implementation of clean energy projects. Implemented projects result in a number of benefits including increased energy efficiency, renewable energy development (when using opportunity fuels), reduced carbon emissions, improved facility economics helping to preserve jobs, and reduced criteria pollutants calculated on an output-based emissions basis. Specific objectives performed by the NW CEAC fall within the following five broad promotion and support categories: 1) Center management and planning including database support; 2) Education and Outreach including plan development, website, target market workshops, and education/outreach materials development 3) Identification and provision of screening assessments & feasibility studies as funded by the facility or occasionally further support of Potential High Impact Projects; 4) Project implementation assistance/trouble shooting; and 5) Development of a supportive clean energy policy and initiative/financing framework.

    Severe wind and snow storms hit the Pacific Northwest region on December 14 – 15, 2006 resulting in major power outagesin the region. The storm is now moving off into southern Canada. A new weather disturbance nearing the Northwest coast may generate a few rain and snow showers across the Seattle and Portland areas today, but widespread active weather is not expected. There are roughly 950,000 customers in the region (including Canada) without power as a result of the Pacific Northweststorms, down from a peak of 1.8 million customers. This represents about 26 percent of customers in affected utility service areas in Oregon and Washington. See table below. As of 12:30 PM EST, the Renton Control Center for the Olympic Pipeline (petroleum products) had power restored. The pipeline, serviced by Puget Sound Energy, was shut down after it lost power during the storm. According to a pipeline official, the pipeline is expected to restart in approximately 2-3 hours with some reduced throughput later today. SeaTac International Airport receives jet fuel from the pipeline; however, it’s been reported that the airport has approximately eight days of jet fuel inventories on hand. There are no reports of problems regarding fuel production. There are some temporary and minor distribution at retail gas stations due to lack of power. Fuel delivery is also slowed in some areas due to delays on some roads. ESF #12 has not been deployed

    2006-03-01

    The Pacific Northwest Loads and Resources Study (White Book), which is published annually by the Bonneville Power Administration (BPA), establishes one of the planning bases for supplying electricity to customers. The White Book contains projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. The White Book also contains information obtained from formalized resource planning reports and data submittals including those from individual utilities, the Northwest Power and Conservation Council (Council), and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for determining BPA revenues, although the database that generates the data for the White Book analysis contributes to the development of BPA's inventory and ratemaking processes. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions that include expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The load resource balance of both the Federal system and the region is determined by comparing resource availability to an expected level of total retail electricity consumption. Resources include projected energy capability plus contract purchases. Loads include a forecast of retail obligations plus contract obligations. Surplus energy is available when resources are greater than loads. This surplus energy could be marketed to increase revenues. Energy deficits occur when resources are less than loads. These energy deficits will be met by any combination of the following: better-than-critical water conditions, demand-side management and conservation

    The Northwest Passage lies in the middle of Canadian Arctic Archipelago providing a potential deepwater route that links the Atlantic and Pacific Oceans. Discovered by Sir Robert M’Clure in the 1850s, ever-present multi-year ice (MYI) has always prevented its practical navigation. 2007 marked extreme low MYI conditions in the Arctic and temporarily cleared the Northwest Passage. However, is one single clearing event within the Northwest Passage over the past 40 years indicative of future clearings? This analysis addressed two inter-related questions: i) why has the Northwest Passage contained historically heavy amounts of MYI? and ii) will decreases in MYI within the Northwest Passage continue into the future? Results indicate that for nearly 4 decades, the southern regions of the Canadian Arctic Archipelago have continuously operated as a drain-trap for MYI and this mechanism is responsible for maintaining the heavy MYI conditions within the Northwest Passage. The oldest and thickest MYI in the world resides along the northern flank of the Canadian Arctic Archipelago therefore, as the transition to a sea ice-free Arctic continues, MYI from this region will continue to migrate southward to the channels of the Northwest Passage. Results also find that 2007 was indeed an anomalously light sea ice year in the Northwest Passage but record low ice conditions have since been observed as of mid-August 2010.

  17. Response of Glaciers to Climate Change in Northwest China

    Li, Z.; Wang, P.

    2015-12-01

    In Northwest China, an extremely dry region, more than 20,000 mountain glaciers are developed. Glacial melt water is vital for local water resources, ecosystem in the lower reaches, peoples' living and city development there. During the past several decades, due to climate warming, the most glaciers in NW China are in a state of rapid retreating. To obtain the general idea on response of glaciers in that region, Tianshan Glaciological Station, Chinese Academy of Sciences selected more than ten glaciers in six sub-regions along Altai Mountain, Tianshan and Qilian Mountain, respectively, doing in-situ observations. Based on field observation and remote sensing technique, this study has revealed that the area reductions in different regions range between 8.8%~34.2 % during the past four decades. The potential impact of the glacier recession on water resource in future will be spatially different. For the Tarim River, the glacier runoff is estimated to maintain its current level or increase somewhat in next 30~50 years. In the north slope of Tianshan, the glaciers with a size smaller than 1 km2 are most likely to be melted away in next 20~40 years, and those larger than 5 km2 are melting intensively. In eastern Xinjiang, because the number of the glaciers is small and also because the climate is extremely dry, the glacier retreating are causing the water shortage problem. For Ili River and Irtysh River, because they are dominant by snow melt runoff, the impact of the glacier shrinkage and temperature rise would be limited on the quantity of the river runoff, but significant on the annual distribution of the river runoff. For Qilian Mountains, glaciers are quite small. The vanishing of small glacier will have significant impact on local water resources in near future.

    The prevalence of epilepsy in Cameroon is higher than that of the industrialized world and other developing countries. Neurocysticercosis due to Taenia solium infestation has been reported as a major cause of epilepsy in some parts of Cameroon although there are some conflicting data. The prevalence of epilepsy is especially high in the Momo division of the North-West Province of Cameroon. We hypothesized that individuals with epilepsy in this region have a higher percentage of seropositivity to T. solium than matched controls. We conducted a case-control study in the Momo subdivision of Ngie. Individuals with epilepsy were recruited from the health centers in Ngie. Control subjects were selected from 19 Ngie villages. Potential cases of people with epilepsy (PWE) were identified through a questionnaire applied by trained field workers, using history of epileptic seizures as a key indicator. Blood samples were taken from all consenting individuals by finger prick, stored in StabilZyme Select, and assayed for antibodies to T. solium in an Atlanta based reference laboratory. We accrued 249 patients with epilepsy, of whom 237 met the inclusion criteria, and 245 age-matched controls. There was no significant difference in seropositivity to T. solium between those individuals with epilepsy (5%) and controls (4.9%). Our data do not support the hypothesis that epilepsy is associated with seropositivity to T. solium. It is highly unlikely that cysticercosis plays a causative role in the high prevalence of epilepsy in this region of Cameroon. Copyright © 2013 British Epilepsy Association.

    During the last 7-year period (2000-2006) atmosphere circulation changes show strong influences on the dust storm deposition dynamics and, as a result, on the primary production dynamics of the northwest African Upwelling System. From 2000 to 2006, the annual mean sea level pressure became higher ranging from 1014 to 1015 mb. Mean annual zonal wind intensity became higher (from 1.1 to 1.8 m s{sup -1}), while the mean annual meridional was reduced from 6.2 to 5.3 m s{sup -1} at the north of the Canary Islands. Mean annual satellite-derived AVHRR/NOAA SST recorded in the northwest African Upwelling became warmer in both locations, from 18.3 deg. C to 18.8 deg. C in Cape Ghir and from 19.5 deg. C to 20.3 deg. C north Canary Islands waters. CHL records from the SeaWiFS/OV-2 showed a different pattern trend. Mean annual CHL levels increased at Cape Ghir from 0.65 mg m-3 to 0.9 mg m-3 and significantly reduced from 0.59 mg m{sup -3} to 0.31 mg m{sup -3} at the north of the Canary Islands. Changes observed in the role of CHL during the last 7-years period could be associated to intensive dust deposition and exceptional weather warming observed in this area since 2000. However, this study focused on a 7-year period and conclusions on possible links between dust deposition and marine biochemistry activity cannot be generalized.

    Based on the investigation data of the vegetations in Hegou valley in Wuqi County of Shaanxi Province, this paper studied the vegetation characteristics on the five typical micro-topography categories including shallow gully, gully, collapse, platform, and scarp in the loess area of north Shaanxi, with the undisturbed slope as the control. There existed distinct differences in the species composition, quantitative characteristics, and species diversity of plant communities on the five typical micro-topography categories and the undisturbed slope. After twelve years of enclosure recovery, the study area formed herbaceous plant community, with Artemisia sacrorum and Artemisia giraldii as the dominant species. Among the main companion species, shrubs such as Prinsepia uni-flora and Caragana korshinskii were found in scarp and gully, and hygrophyte Phragmites australis appeared in platform. The coverage, height, and biomass of the plant communities on most of the micro-topography categories, especially on the gully and collapse, were larger than those on the undisturbed slope. The Shannon index on the micro-topography categories and undisturbed slope was in the order of scarp > gully> shallow gully> undisturbed slope> platform> collapse.%以陕西省吴起县合沟流域内微地形及原状坡面的植被调查数据为基础,研究浅沟、切沟、塌陷、缓台和陡坎5种黄土高原典型微地形植被特征及其与原状坡面的差异.结果表明:黄土区封禁流域坡面微地形内植物群落物种组成、数量特征及其多样性存在明显差异.经过12年的自然恢复,研究区域形成以铁杆蒿和茭蒿为优势种的草本群落,伴生种中,陡坎和切沟出现灌木扁核木和柠条,缓台出现湿生性植物芦苇.微地形植被的盖度、平均高度和生物量多优于原状坡面,且以切沟和塌陷最为显著.不同微地形Shannon指数的大小顺序为陡坎>切沟>浅沟>原状坡面>缓台>塌陷.

    A total of 3708 1 x 1 deg free-air gravity anomaly averages have been used to construct a new 1 x 1 deg gravimetric geoid of the Northwest Pacific Ocean. The 1 x 1 deg averages are based on a compilation of 147,000 surface ship and pendulum gravity measurements. Difference geoid undulations range from a maximum of +19 m over the Hawaiian ridge to a minimum of -31 m over the junction of the Kuril and Aleutian trenches. The Hawaiian swell is associated with a geoidal high of up to +15 m with wavelengths of about 2200 km and the topographic rises seaward of deep-sea trenches are associated with geoidal highs of up to 4 m with wavelengths of about 220-900 km. The agreement between the gravimetric geoid and Skylab-4 and Geos-3 altimeter data is close for wavelengths greater than about 300 km but poor for shorter wavelengths.

    Despite a small storm that came through the area last night with wind gusts peaking at 45 MPH, progress continues to be made in restoring power to customers who lost power during the December 14-15 storms which hit the Pacific Northwest region. Currently, 95,971 customers remain without power, down from 1.8 million customers. The wind storm which affected the area yesterday was not as bad as previously expected, with the majority of the customer outages in the BC Hydro region, and 3,000 additional customer outages in the Puget Sound Energy service area. The customers without power represent 5 percent of customers in the affected utility service areas of Washington. The majority of customers without power are served by Puget Sound Energy, BC Hydro, and Seattle City Light.

    White sharks are highly migratory apex predators, globally distributed in temperate, sub-tropical, and tropical waters. Knowledge of white shark biology and ecology has increased recently based on research at known aggregation sites in the Indian, Atlantic, and Northeast Pacific Oceans; however, few data are available for the Northwest Pacific Ocean. This study provides a meta-analysis of 240 observations of white sharks from the Northwest Pacific Ocean between 1951 and 2012. Records comprise reports of bycatch in commercial fisheries, media accounts, personal communications, and documentation of shark-human interactions from Russia (n = 8), Republic of Korea (22), Japan (129), China (32), Taiwan (45), Philippines (1) and Vietnam (3). Observations occurred in all months, excluding October-January in the north (Russia and Republic of Korea) and July-August in the south (China, Taiwan, Philippines, and Vietnam). Population trend analysis indicated that the relative abundance of white sharks in the region has remained relatively stable, but parameterization of a 75% increase in observer effort found evidence of a minor decline since 2002. Reliably measured sharks ranged from 126-602 cm total length (TL) and 16-2530 kg total weight. The largest shark in this study (602 cm TL) represents the largest measured shark on record worldwide. For all countries combined the sex ratio was non-significantly biased towards females (1∶1.1; n = 113). Of 60 females examined, 11 were confirmed pregnant ranging from the beginning stages of pregnancy (egg cases) to near term (140 cm TL embryos). On average, 6.0±2.2 embryos were found per litter (maximum of 10) and gestation period was estimated to be 20 months. These observations confirm that white sharks are present in the Northwest Pacific Ocean year-round. While acknowledging the difficulties of studying little known populations of a naturally low abundance species, these results highlight the need for dedicated research to

    The long-term environmental and economic sustainability of agriculture in the Inland Pacific Northwest (northern Idaho, north central Oregon, and eastern Washington) depends upon improving agricultural management, technology, and policy to enable adaptation to climate change and to help realize agriculture's potential to contribute to climate change mitigation. To address this challenge, three land-grant institutions (Oregon State University, the University of Idaho and Washington State University) (OSU, UI, WSU) and USDA Agricultural Research Service (ARS) units are partners in a collaborative project - Regional Approaches to Climate Change for Pacific Northwest Agriculture (REACCH-PNA). The overarching goal of REACCH is to enhance the sustainability of Inland Pacific Northwest (IPNW) cereal production systems under ongoing and projected climate change while contributing to climate change mitigation. Supporting goals include: - Develop and implement sustainable agricultural practices for cereal production within existing and projected agroecological zones throughout the region as climate changes, - Contribute to climate change mitigation through improved fertilizer, fuel, and pesticide use efficiency, increased sequestration of soil carbon, and reduced greenhouse gas (GHG) emissions consistent with the 2030 targets set by the USDA National Institute for Food and Agriculture (NIFA), - Work closely with stakeholders and policymakers to promote science-based agricultural approaches to climate change adaptation and mitigation, - Increase the number of scientists, educators, and extension professionals with the skills and knowledge to address climate change and its interactions with agriculture. In this poster, we provide an overview of the specific goals of this project and activities that are underway since its inception in spring of 2011.

    The objective of the Pacific Northwest Regional Assessment Program is to establish and exercise an integrated analytical assessment program for evaluation of potential changes that may result from various energy development or conservation scenarios. Such scenarios may themselves result from Federal development policies and programs, from regionally specific actions by the states and energy industries, or from actions taken by international factors currently importing energy resources into the region. After consideration of a variety of approaches to integrated assessment at a regional level, Battelle Pacific Northwest Laboratories (BNW) has concluded that dynamic simulation techniques provide the best available approach to evaluating the issues pertinent to the Northwest. As a result, the Pacific Northwest Regional Assessment Program has been structured in a framework involving ten sectors. Each of these sectors involve their own submodels that receive information either from outside the model as exogenous inputs or from other sector submodels.

  10. Geologic framework, age, and lithologic characteristics of the North Park Formation in North Park, north-central Colorado

    Science.gov (United States)

    Shroba, Ralph R.

    2016-10-18

    Deposits of the North Park Formation of late Oligocene and Miocene age are locally exposed at small, widely spaced outcrops along the margins of the roughly northwest-trending North Park syncline in the southern part of North Park, a large intermontane topographic basin in Jackson County in north-central Colorado. These outcrops suggest that rocks and sediments of the North Park Formation consist chiefly of poorly consolidated sand, weakly cemented sandstone, and pebbly sandstone; subordinate amounts of pebble conglomerate; minor amounts of cobbly pebble gravel, siltstone, and sandy limestone; and rare beds of cobble conglomerate and altered tuff. These deposits partly filled North Park as well as a few small nearby valleys and half grabens. In North Park, deposits of the North Park Formation probably once formed a broad and relatively thick sedimentary apron composed chiefly of alluvial slope deposits (mostly sheetwash and stream-channel alluvium) that extended, over a distance of at least 150 kilometers (km), northwestward from the Never Summer Mountains and northward from the Rabbit Ears Range across North Park and extended farther northwestward into the valley of the North Platte River slightly north of the Colorado-Wyoming border. The maximum preserved thickness of the formation in North Park is about 550 meters near the southeastern end of the North Park syncline.The deposition of the North Park Formation was coeval in part with local volcanism, extensional faulting, development of half grabens, and deposition of the Browns Park Formation and Troublesome Formation and was accompanied by post-Laramide regional epeirogenic uplift. Regional deposition of extensive eolian sand sheets and loess deposits, coeval with the deposition of the North Park Formation, suggests that semiarid climatic conditions prevailed during the deposition of the North Park Formation during the late Oligocene and Miocene.The North Park Formation locally contains a 28.1-mega-annum (Ma

  11. Geographic distribution and dispersal of normapolles genera in North America

    Tschudy, R.H.

    1981-01-01

    Normapolles pollen have been found in North America in Cretaceous and Lower Tertiary rocks from the eastern Atlantic Seaboard, the Mississippi embayment region and from the states and provinces from western North America as far north as the District of Mackenzie, Northwest Territories. Previous postulates relating to the Normapolles floral province (western Europe-eastern North America) were re-examined in the light of new finds of Normapolles genera in rocks from west of the Cretaceous epeiric seaway which separated the Normapolles province from the western North American Aquilapollenites province. A study of published occurrences of Normapolles genera and U.S. Geological Survey Denver Laboratory Normapolles records revealed that of the approximately 60 Normapolles genera recognized from western Europe, only 26 of these have been recognized from eastern North America. These data suggest that Normapolles-producing plants originated in western Europe and migrated to eastern North America prior to the opening of the north Atlantic seaway. Ten of these 26 genera also have been found in rocks from west of the Cretaceous epeiric seaway, suggesting that these genera were the only ones able to cross this barrier. At least six genera having Normapolles characteristics occur in eastern North America but have not yet been recorded from Europe. Two additional genera with Normapolles characteristics have been reported only from the Aquilapollenites province of western North America. Several discrepancies in the record need resolution, such as the latitudinal restriction of Thomsonipollis and Nudopollis to areas south 40??N latitude, the absence of records of Thomsonipollis east and north of central Georgia, and the absence of records of Kyandopollenites and Choanopollenites west of eastern Texas. These data show that the known boundaries of the Normapolles province are somewhat hazy and that firm conclusions regarding the geographic distribution and history of dispersal of

  12. Residential fuel choice in the Pacific Northwest

    Energy Technology Data Exchange (ETDEWEB)

    Lee, A.D.; Englin, J.E.; Harkreader, S.A.

    1989-02-01

    In 1983, the Northwest Power Planning Council (Council) issued Model Conservation Standards (MCS) designed to improve the efficiency of electrically heated buildings. Since then, the standards have been adopted by numerous local governments and utilities. The Bonneville Power Administration (Bonneville) has played an active role in marketing residential energy efficiency improvements through the Super Good Cents Program (SGCP) and encouraging the adoption and implementation of the MCS as local codes through the Early Adopter Program (EAP). Since the inception of the MCS, however, questions have arisen about the effect of the code and programs on the selection of heating fuels for new homes. Recently, Bonneville has proposed a gradual reduction in the incentive levels under these two programs prior to 1995 based on several assumptions about the market for MCS homes: builder costs will decline as builders gain experience building them; buyers will seek out MCS homes as their appreciation for their lower energy costs and greater comfort increases; and the resale market will increasingly reflect the greater quality of MCS homes. The growing availability of data from several jurisdictions where the MCS have been implemented has recently made it possible to begin assessing the effect of the MCS programs on residential fuel choice and evaluating assumptions underlying the programs and Bonneville's plans to revise them. This study is the first such assessment conducted for Bonneville.

    The martian meteorite Northwest Africa 7034 (and pairings) is a breccia that provides important information about the rocks and processes of the martian crust (e.g., 1-3). Additional information can be gleaned from the components of the breccia. These components, specifically those designated as clasts, record the history of their parent rock (i.e., the rock that has been physically broken down to produce the clasts). In order to study these parent rocks, we must first determine which clasts within the breccia are de-rived from the same parent. Previous studies have be-gun this process (e.g., 4), but the search for genetic linkages between clasts has not integrated clasts with different grain sizes. We begin to take this approach here, incorporating igneous-textured clasts with both fine and coarse mineral grains. In NWA 7034, almost all materials (clasts and breccia matrix) are composed of the same mineral assemblages (feldspar, pyroxene, Fe-Ti oxides, apatite) with largely the same mineral compositions [1, 4-6]. Bulk breccia Sm-Nd systematics define a single isochron [7]. These observations are consistent with a majority of the components within NWA 7034 originating from the same geochemical source and crystallizing at roughly the same time.

  14. Genetic structure of capelin (Mallotus villosus in the northwest Atlantic Ocean.

    Directory of Open Access Journals (Sweden)

    Ellen L Kenchington

    Full Text Available Capelin (Mallotus villosus is a commercially exploited, key forage-fish species found in the boreal waters of the North Pacific and North Atlantic Oceans. We examined the population structure of capelin throughout their range in the Canadian northwest Atlantic Ocean using genetic-based methods. Capelin collected at ten beach and five demersal spawning locations over the period 2002 through 2008 (N = 3,433 fish were genotyped using six polymorphic microsatellite loci. Temporally distinct samples were identified at three beach spawning locations: Chance Cove, Little Lawn and Straitsview, Newfoundland. Four capelin stocks are assumed for fisheries management in the northwest Atlantic Ocean based on meristics, morphometrics, tag returns, and seasonal distribution patterns. Our results suggested groupings that were somewhat different than the assumed structure, and indicate at least seven genetically defined populations arising from two ancestral populations. The spatial mosaic of capelin from each of the two basal cluster groups explains much of the observed geographic variability amongst neighbouring samples. The genetic-defined populations were resolved at Jost's Dest ≥ 0.01 and were composed of fish collected 1 in the Gulf of St. Lawrence, 2 along the south and east coasts of Newfoundland, 3 along coastal northern Newfoundland and southern Labrador, 4 along coastal northern Labrador, 5 near the Saguenay River, and at two nearshore demersal spawning sites, 6 one at Grebes Nest off Bellevue Beach on the east coast of Newfoundland, and 7 one off the coast of Labrador at Domino Run. Moreover, the offshore demersal spawners on the Scotian Shelf and Southeast Shoal appeared to be related to the inshore demersal spawners at Grebes Nest and in Domino Run and to beach spawners from the Gulf of St. Lawrence.

  15. Tropical Pacific impacts on cooling North American winters

    Science.gov (United States)

    Sigmond, Michael; Fyfe, John C.

    2016-10-01

    The North American continent generally experienced a cooling trend in winter over the early 2000s. This cooling trend represented a significant deviation from expected anthropogenic warming and so requires explanation. Previous studies indicate that climate variations in the tropical Pacific contributed to many mid-latitude climate variations over the early twenty-first century. Here we show using large ensembles of fully coupled, partially coupled and uncoupled model simulations that in northwest North America the winter cooling was primarily a remote response to climate fluctuations in the tropical Pacific. By contrast, in central North America the winter cooling appears to have resulted from a relatively rare fluctuation in mid-latitude circulation that was unrelated to the tropical Pacific. Our results highlight how decadal climate signals--both remote and local in origin--can together offset anthropogenic warming to produce continental-scale cooling.

    occurs within the deposit. Although the avalanche and associated debris flow surfaces on the northwest slope appear pristine, being only partially covered by lava flow from a volcano in one of the channels, those on the southeast slope are partially buried by postfailure volcanics and detrital sediments. At the distal end of the slope failure masses, there are extensive fans. On the southeast slope these depocenters were reworked into a sediment drift field of northeast trending ridges by the southerly flowing North Atlantic Deep Water. On the surfaces of the fans off the northwest slope, there are exotic blocks transported downslope from their original positions either by riding on the surface of the highly dense debris avalanche or by being transported within the avalanche itself.

  17. North Pacific atmospheric rivers and their influence on western North America at the Last Glacial Maximum

    Lora, Juan M.; Mitchell, Jonathan L.; Risi, Camille; Tripati, Aradhna E.

    2017-01-01

    Southwestern North America was wetter than present during the Last Glacial Maximum. The causes of increased water availability have been recently debated, and quantitative precipitation reconstructions have been underutilized in model-data comparisons. We investigate the climatological response of North Pacific atmospheric rivers to the glacial climate using model simulations and paleoclimate reconstructions. Atmospheric moisture transport due to these features shifted toward the southeast relative to modern. Enhanced southwesterly moisture delivery between Hawaii and California increased precipitation in the southwest while decreasing it in the Pacific Northwest, in agreement with reconstructions. Coupled climate models that are best able to reproduce reconstructed precipitation changes simulate decreases in sea level pressure across the eastern North Pacific and show the strongest southeastward shifts of moisture transport relative to a modern climate. Precipitation increases of ˜1 mm d-1, due largely to atmospheric rivers, are of the right magnitude to account for reconstructed pluvial conditions in parts of southwestern North America during the Last Glacial Maximum.

    1998-12-01

    Full Text Available Wetlands in natural areas in South Africa have been described before, but no literature exists concerning the phyto­sociology of urban wetlands. The objective of this study was to conduct a complete vegetation analysis of the wetlands in the Potchefstroom Municipal Area. Using a numerical classification technique (TWINSPAN as a first approximation, the classification was refined by using Braun-Blanquet procedures. The result is a phytosociological table from which a number of unique plant communities are recognised. These urban wetlands are characterised by a high species diversity, which is unusual for wetlands. Reasons for the high species diversity could be the different types of disturbances occurring in this area. Results of this study can be used to construact more sensible management practises for these wetlands.  

  20. TRANSPARENCY OF LOCAL BUDGETS IN THE NORTH-WEST REGION OF ROMANIA

    2013-07-01

    Full Text Available The central researched element in our paper is the local budgets, the basic component of local public finances. Local budgets, like any other budgets, are the most important tool for the management (of local governments planning, forecasting, implementing and monitoring the results of administrative-territorial units activity, also being an appropriate tool for enhancing performance. A budget is the government's plan regarding the use of public resources to meet the citizens' needs. The aim of this paper is to realize a research on budget transparency in local governments from the Nord-West Region of Romania, regarding the availability of the budget information on the websites of the county councils and the county residences. The key element of good governance in today global economic environment is transparency that can be defined as the openness of public authorities (central and local regarding their policy intention, formulation and implementation. For local governments budget transparency is an important issue, due to the growing role of administrative-territorial units, confirmed over time by the economic reality. The importance of local budgets has increased in recent years due to the need to improve management efficiency and accounting al the level of local governments. Not only policy makers but also the citizens need information regarding local government current activities, expenditures, development projects and policies. In this context of a growing need for information, the transparency of local budgets is a mandatory condition for any local government. The combination of budget transparency and public participation in budget processes has the potential to combat corruption, foster public accountability of government agencies and contribute to judicious use of public funds. In this context, budget transparency represents the mean through which ordinary citizens and civil society organizations can access information about the allocation and use of public resources, so that they can assess how government officials manage public funds. Budget transparency needs to be implemented due to the benefits it brings and the most important one is obtaining better budgetary outcomes.

    Full Text Available Public debt is a topic of great interest problem tracked over the years and has worsened with the outbreak of the second wave of financial crisis around the world, namely the sovereign debt crisis. After BREXIT the EU must urgently adopt uniform tax measures to prevent a new crisis of sovereign debt in countries like Greece, Italy, Spain, Portugal, and for the meeting the Maastricht criteria on public debt. UE countries have to adopting a pro - active stance by continuing fiscal consolidation measures. That is why in this paper the authors present an analysis of local public debt based on a correlated system of indicators.

  2. Pronounced subsurface cooling of North Atlantic waters off Northwest Africa during Dansgaard-Oeschger interstadials

    Millennial-scale Atlantic meridional overturning circulation (AMOC) variability has often been invoked to explain the Dansgaard-Oeschger (DO) events. However, the underlying causes responsible for millennial-scale AMOC variability are still debated. High-resolution U37K' and TEX86H temperature records for the last 50 kyr obtained from the tropical Northeast (NE) Atlantic (core GeoB7926-2, 20°13'N, 18°27'W, 2500 m water depth) show that distinctive DO-type subsurface (i.e. below the mixed layer: >20 m water depth) temperature oscillations occurred with amplitudes of up to 8 °C in the tropical NE Atlantic during Marine Isotope Stage 3 (MIS3). Statistical analyses reveal a positive relationship between the reconstructed substantial cooling of subsurface waters and prominent surface warming over Greenland during DO interstadials. General circulation model (GCM) simulations without external freshwater forcing, the mechanism often invoked in explaining DO events, demonstrate similar anti-phase correlations between AMOC and pronounced NE Atlantic subsurface temperatures under glacial climate conditions. Together with our paleoproxy dataset, this suggests that the vertical temperature structure and associated changes in AMOC were key elements governing DO events during the last glacial.

  3. Mapping and deterring violent extremist networks in North-West Africa

    DEFF Research Database (Denmark)

    Walther, Olivier; Leuprecht, Christian

    This article examines the structural and spatial organization of violent extremist organizations (VEOs) across the Sahara. Building on the Armed Conflict Location and Event Dataset (ACLED), a public collection of political violence data for developing states, the article investigates structural...... connections of VEOs and the effect of borders on the spatial patterns of armed groups. Social network analysis reveals that the network involving VEOs had a low density, a low level of transitivity, and contained few central actors, three typical characteristics of negative-tie networks. Al Qaeda...... in the Islamic Maghreb (AQIM) is unquestionably the most connected VEO, which in purely network terms can be seen as a liability. Spatial analysis shows that, while violence was almost exclusively concentrated within Algeria between 1997 and 2004, cross-border movements intensified in the mid-2000s following...

    A continuous aerobiological survey of the atmosphere of Bursa was carried out from 1st January 2003 to 31st December 2004 by means of the volumetric method using a Lanzoni trap. During 2 years, a total of 57,124 pollen grains/m(3), which belonged to 66 taxa and 869 unidentified pollen grains, were recorded. In the region investigated, Pinus sp., Olea sp., Platanus sp., Cupressaceae/Taxaceae, Quercus sp., Poaceae, Moraceae, Urticaceae, and Castanea sp. were responsible for the greatest amounts of pollen. During the study period, the pollen concentration reached the highest level in May. A correlation analyses was made between the daily fluctuations of the main pollen types and meteorological parameters.

    2011-06-01

    Full Text Available The pond snail Lymnaea auricularia serves as an intermediate host for many digenian species. In West Azerbaijan province, northwestern Iran, the cercariae infection investigation was undertaken in L. auricularia from May to November 2010. Of 6759 collected Lymnaeid snails, 370(5.5% L. auricularia snails were identified. Cercariae infection was found in a number of 276 (74.56 % snails. The results showed that removed cercariae from L. auricularia belonged to Echinostomcercariae (96.38 % and Furcocercariae (3.62 % which were found in two out of 28 sites during the course of study. In summer and fall, the highest prevalence of cercariae infection was recorded for both identified cercariae. It is concluded that L. auricularia could be an important intermediate host of large group digenian trematodes in the region, which is necessary to take consideration in the control program of trematode infection.

    Full Text Available Objectives. The frequency of adult-type hypolactasia (lactase non-persistence varies widely among different ethnic groups. The cultural historical hypothesis assumes a link between the occurrence of hypolactasia and the distribution of dairy farming. The nomadic Nenets have been reindeer herders for generations and have therefore not consumed any dairy products. The hypotheses here was that the prevalence of lactase non-persistence (−13910 C/C genotype among Nenets people having four Nenets grandparents is high, while the prevalence among Nenets originating from ethnically mixed families is lower. Study design. The material was collected in four typical Nenets settlements in the Nenets Autonomous Okrug in Russia. One-third of the adult Nenets population were invited to answer a questionnaire and to donate buccal samples for genotyping by a doctor from the team of medical professionals who make rounds in this area. The total number of available participants was 177. Methods. Genotyping was performed with the AbiPrism system. We used the method of concordance of grandparents’ national origin to ascribe ethnicity. Results. The prevalence of adult-type hypolactasia (−13910 C/C among Nenets who had four Nenets grandparents was found to be 90%. The figures among others reporting three, two and one grandparent of Nenets origin were 72, 60 and 28%, respectively. Conclusion. The findings are in accord with the cultural historical hypothesis.

    Full Text Available Abstract Background Neoehrlichia mikurensis s an emerging and vector-borne zoonosis: The first human disease cases were reported in 2010. Limited information is available about the prevalence and distribution of Neoehrlichia mikurensis in Europe, its natural life cycle and reservoir hosts. An Ehrlichia-like schotti variant has been described in questing Ixodes ricinus ticks, which could be identical to Neoehrlichia mikurensis. Methods Three genetic markers, 16S rDNA, gltA and GroEL, of Ehrlichia schotti-positive tick lysates were amplified, sequenced and compared to sequences from Neoehrlichia mikurensis. Based on these DNA sequences, a multiplex real-time PCR was developed to specifically detect Neoehrlichia mikurensis in combination with Anaplasma phagocytophilum in tick lysates. Various tick species from different life-stages, particularly Ixodes ricinus nymphs, were collected from the vegetation or wildlife. Tick lysates and DNA derived from organs of wild rodents were tested by PCR-based methods for the presence of Neoehrlichia mikurensis. Prevalence of Neoehrlichia mikurensis was calculated together with confidence intervals using Fisher's exact test. Results The three genetic markers of Ehrlichia schotti-positive field isolates were similar or identical to Neoehrlichia mikurensis. Neoehrlichia mikurensis was found to be ubiquitously spread in the Netherlands and Belgium, but was not detected in the 401 tick samples from the UK. Neoehrlichia mikurensis was found in nymphs and adult Ixodes ricinus ticks, but neither in their larvae, nor in any other tick species tested. Neoehrlichia mikurensis was detected in diverse organs of some rodent species. Engorging ticks from red deer, European mouflon, wild boar and sheep were found positive for Neoehrlichia mikurensis. Conclusions Ehrlichia schotti is similar, if not identical, to Neoehrlichia mikurensis. Neoehrlichia mikurensis is present in questing Ixodes ricinus ticks throughout the Netherlands and Belgium. We propose that Ixodes ricinus can transstadially, but not transovarially, transmit this microorganism, and that different rodent species may act as reservoir hosts. These data further imply that wildlife and humans are frequently exposed to Neoehrlichia mikurensis-infected ticks through tick bites. Future studies should aim to investigate to what extent Neoehrlichia mikurensis poses a risk to public health.

    Splash erosion is generally acknowledged as the main erosive agent, because it represents the first step in water erosion (Ellison, 1944, Sempere Torres et al., 1994). The impact of raindrops not only modifies the structure of the earth's surface, (Moss, 1991) but also breaks down and emits soil fragments which are later transported over long distances in the case of additional surface runoff processes (Moss and Green, 1983). In the whole process we need to take into account not only the specific kinetic energy associated to each rain event, but also the type of soil and the size of the particles released (Sharma et al 1991), as well as the characteristics of the layer of water formed on the surface (Moss and Green, 1983, Kinnell, 1991, Leguédois et al., 2005). The erosion process is more obvious when it affects vulnerable areas that have recently been devastated by a wildfire. This study has computed the raindrop size, its volume, the fall velocity, and its kinetic energy by means of an optical disdrometer. The data have subsequently been compared with the mass of soil that was splashed and collected in a particular area devastated by an important wildfire on the 17th of May 2012. The splash erosion produced in 6 months has been analyzed. 2. Study Site The data were gathered in the period between the 29th May and the 30th November 2012, in the area of Congosto, in the province of León, Spain. The study zone is part of a transition area between the plain and the mountainous regions. The dominant climate is the continentalized Mediterranean climate, although with more moderate temperatures. In general, in this area we find a wide temperature range (from 12 to 20°C), long and cold winters, short springs and autumns, and short and warm summers. Precipitation is irregularly scattered along the year, and may reach, depending on the area, up to 1,500 mm per year. Intense precipitation events may occur. The area presents a coarse-grained siliceous lithology, that is, quartzite with sandstone and slate, with a soil cover of inceptisol of franc-sandy texture. The vegetation, which is the first defense line against erosion in the area, is limited to holm oaks and pine trees, all of which were virtually eliminated by the virulence of the wildfire in May 2012. 3. Materials and Methods Precipitation was measured using a Thies optical disdrometer which registers raindrop size spectra every minute. This device is described in detail in Bloemink and Lanzinger (2005). The instruments used to carry out this study on splash erosion have been the funnels described in Fernández-Raga 2010. The area affected by the wildfire was divided into 2 sections, one former pine tree area, and another former scrubland area. Five sampling points were installed in each area. Similar control areas were established in the part of land not affected by the fire, with the same type of vegetation, and with another 5 sampling points in each case. In addition, control devices were installed to collect airborne soil. 4. The kinetic energy of rain The kinetic energy of rain was assessed using data obtained by the disdrometer: raindrop size distribution (DSD). This information enables us to compute the mass of the raindrop and its fall velocity (Ryzhkov et al 1999). To compute the mass, we need to know the shape of the drop. The shape of raindrops has been the object of many previous studies (Brandes, 2002, Sansom, 2004). The main conclusion is that drops smaller than 1 mm are spherical, but raindrops with diameters larger than 1 mm take on a shape that resembles more an ellipsoid. Considering that size, we adopt a polynomial equation of degree 12 (Fernández-Raga 2010). 5. Evolution of splash erosion The study has assessed the amount of splash erosion as well as its composition. In addition, the erosion caused has been compared with the regeneration of the vegetation in the area. The results reveal a very slow recovery of the vegetation in the study zone, and a halt in the amount of soil affected by splash erosion until now. 5. Results and Conclusions It was found that the precipitation in Congosto has a nearly exponential drop size distribution (DSD), except for large sizes. It can also be noted that drops between the sizes of 2 and 2.5 mm are the ones that contribute more to the kinetic energy hitting the ground. The comparison between the splash erosion registered and the total kinetic energy in each rain event has led to the following conclusions: • The DSD of precipitation in Congosto follows an exponential or gamma distribution. The energy distribution, on the other hand, is a gamma distribution. • Splash erosion has been found to be very important in the area devastated by the wildfire in the 2 months immediately after the fire. Later, splash erosion decreases, though it remains relatively high despite fewer rain events during the summer. • The vegetation has not recovered at all in the 6 months that followed the wildfire. • The soil analysis reveals a high degree of degradation caused by the wildfire. 6.

    An area of fine sediment off the Cumbrian coast acts as a reservoir for many of the radionuclides discharged into the Irish Sea from Sellafield. The origin of any sediment that could come ashore in a single storm event has been evaluated, the areas of coast that could be at risk from flooding have been identified and an assessment made of the doses that might be received as a result of such flooding. Any sediment transported inland would have come from the nearshore zone rather than directly from the offshore area. Moreover, although parts of the coast between Morecambe Bay and the Solway are currently at risk from flooding during severe storms, the doses that would be received by those engaged in the clean-up operations and by residents would be a small fraction of the limit recommended by ICRP for members of the public.

    Groundwater is the primary source of drinking water for more than 95% of the population in Punjab. The world health organization and US Environment Protection Agency recently established a new maximum contaminant level of 10 ppb for arsenic in drinking water. The arsenic concentration of deep water tube wells located in Amritsar city used for domestic supply for urban population ranged from 3.8 to 19.1 ppb with mean value of 9.8 ppb. Arsenic content in hand pump water varied from 9 to 85 ppb with a mean value of 29.5 ppb. According to the safe limit of As, 54% and 97%, water samples collected from deep water tube wells and hand pumps, respectively, were not fit for human consumption. Arsenic content in canal water varied from 0.3 to 8.8 ppb with a mean value of 2.89 ppb. Canal water has got higher oxidation potential followed by deep tube well and hand pump water. The present study suggests the regular monitoring of arsenic content in deep tube well and shallow hand pump waters by water testing laboratories. The consumption of water having elevated concentration of As above the safe limit must be discouraged. In south-western districts of Punjab, it recommends the use of canal water for drinking purposes and domestic use by rural and urban populations than ground water sources.

    Full Text Available India is located at a very strategic point with respect to the international commercial sea routes with a large amount of crude oil traffic. Hence, the risk of oil spill occurring in the Indian waters is considerably high. In the present paper, forecasting the movement of a possible crude oil spill of 10,000 barrels at a location of latitude 21° 41′ 48.53′ N and longitude 66° 46′ 41.45″ E, intersection point of two ship routes from Kandla port and Bombay port (Kandla port of India to Yanbu port of Saudi Arabia and Bombay port of India to Ras Tanura port of Saudi Arabia has been carried out using GNOME (General NOAA Operational Modeling Environment model developed by Hazardous Materials Response Division (HAZMAT of the National Oceanic and Atmospheric Administration Office of Response and Restoration (NOAA OR&R of United States government. The governing equations for horizontal diffusion, evaporation, dissolution, dispersion etc, adopted by GNOME have been presented in the paper. The simulation is carried out for month of September 2011. It is found that the spill possibly takes 10 hours to reach Gujarat coast and 15 hours to reach Maharashtra coast. With this available knowledge, appropriate mitigation measures may be adopted before spill reaches the shores.

    Mangrove ecosystems are coastal estuarine systems confined to the tropical and subtropical regions. The Estero Salado mangrove located in Guayaquil, Ecuador, has suffered constant disturbances during the past 20 years, due to industrial wastewater release. However, there are no published data for heavy metals present in its sediments and the relationship with anthropogenic disturbance. In the present study, metal concentrations were evaluated in surface sediment samples of the mangrove, showing that B, Cd, Cu, Pb, Se, V, and Zn levels exceeded those declared in international environmental quality standards. Moreover, several metals (Pb, Sn, Cd, Ag, Mo, Zn and Ni) could be linked to the industrial wastewater present in the studied area. In addition, heavy metal levels detected in this mangrove are higher than previous reports on mangrove sediments worldwide, indicating that this mangrove ecosystem is one of the most disrupted on earth.

    Full Text Available The current study proposes a comparative approach of two forms of non-formal educational activities: the school trip and the scientific educational academic trip with their similarities and differences regarding both tourist and pedagogical levels. In order to acquire this goal the following objectives have been set: analysing a geographical-tourist itinerary, analysing the involved tourist services, analysing the trip planner for the specified itinerary, analysing certain teaching activities, differentiated based on the level of study (pre-university/superior, analysing students and undergraduates’ worksheets after they have been completed according to the requirements. Consequently a series of similarities have appeared between the school trip and the academic trip, especially related to the theme, purpose, evaluation form, participants’ involvement degree, structure and integrated tourist elements (from attractions to services. On the other hand, the main differences that were highlighted, starting with educational level, age difference, and participants’ number have had repercussions on the quantitative and qualitative particularities of the tasks and last but not least, on the evaluation product (students’ portfolios and undergraduates’ trip notebooks.

    Over the last millions years, the crustal shortening across the Himalaya of the Indian Kashmir have been accommodated by three sub-parallel emerging thrusts: the Main Boundary Thrust (MBT), the Medlicott-Wadia Thrust (MWT) and the Main Frontal Thrust (MFT). The alternate occurrence of in sequence and out of sequence deformational patterns at the historical time-scale confirm that the seismogenic activity can shift from one thrust to a sub-parallel one, connected at depth to the same main décollement. In such a sismo-tectonic context, a fundamental issue is to identify the structures absorbing the most part of the deformation and to quantify the shortening rates through them. This yields important implications in terms of seismogenic potential and natural hazard for the densely populated region. We studied the geometry of the alluvial terraces and fans across the three main thrusts (MBT, MWT and MFT) in order to quantify the amount of cumulated Late Quaternary deformation. Then we dated these markers to estimate slip rates along these thrust faults. The main result is that all the deformation since at least ~15 ka is absorbed on the two most external thrusts (i.e. MWT and MFT), with rates in the order of 1cm/yr, while the regional segment of the Main Boundary Thrust is no more active. We excavated a paleoseismological trench across the MWT, the only active structure reaching the surface. Our analysis of the deformations within the alluvial-colluvial material coupled with 14C dating suggests that the most recent event is ascribed to the last strong Kashmiri earthquake (1555). The ruptures associated with this event, as well as those associated to at least two older events, show minimum co-seismic displacements of several meters. This portion of the MWT shows litho-structural analogies - steep ramp and old cratonic basement at the hanging-wall - with the Balakhot Bagh Fault (Pakistan) affected by Mw 7.6 event in 2005. However, in Indian Kashmir, the five centuries seismic gap over a 100-km segment, the slip rate across the fault and the amplitude of the co-seismic paleo-displacements, all converge for the possibility of an even greater magnitude on this fault in the next decades.

    From January 1976 to July 1978, 234 ill neonates were transported to the regional neonatal intensive care unit (ICU) of St Mary's Hospital, Manchester, from 26 maternity hospitals three to 120 miles (4.8-193.1 km) away. Ninety per cent were transferred from 15 hospitals within a 30-mile (48.3 km) radius of the ICU. Most referring hospitals had more than 2000 births a year and offered good nursing supervision of high-risk neonates in conventional special care baby units (SCBUs). In 200 of the 234 babies respiratory symptoms precipitated referral, hyaline membrane disease being the most common final diagnosis. Altogether 143 babies received definitive mechanical ventilation, and most of them were ventilated in the ambulance en route to the ICU. The neonatal survival rates for all babies and for those who received mechanical ventilation were 61% and 45% respectively. Lethal inoperable malformations and tentorial tears accounted for 23 of the 92 deaths.A crisis-orientated referral service directed towards the treatment of babies with impending or actual respiratory failure needs close collaboration between the regional ICU and referring SCBUs, with parallel development of their facilities and skills. A complementary but distinct pattern of referral is necessary to cater for those high-risk but not critically ill babies who are born in hospitals that lack staff and facilities to provide the vigilant and anticipatory care that is so necessary.

    Full Text Available Background: Several studies have indicated that when compared to non-consanguinous marriage, consanguinous marriage may lead to a higher incidence of congenital abnormalities. The study was performed to evaluate few screening tests to estimate the risk of chromosomal abnormalities in the first trimester compared between familial and non-familial marriages. Materials and Methods: In this cross sectional study, 300 pregnant women with singleton pregnancy presenting to Tabriz Al-Zahra hospital from 2007 to 2009 were enrolled as study population. The participants were evaluated about chromosomal malformations using a combination of NT (Nuchal Translucency, PAPP-A (Pregnancy-Associated Plasma Protein A, and free beta- human chorionic gonadotropin (β-hCG. In positive screening test results, the participants underwent fetal karyotyping using amniocentesis or chorionic villi sampling (CVS.Results: Pregnancies with higher risk were observed more among non-consanguineous marriages. The maternal age was not found to be a determinant in this regard. NT and free β-hCG values (but not PAPP-A were significantly different between the two study groups. The triple screening test had a sensitivity of 100%. There were two cases of Down syndrome both belonging to the maternal age less than 35 years and non-consanguineous marriages.Conclusion: Considering that a statistically significant association was not observed between abnormal test results and pregnancy complications (p=0.73, it seems that it is essential to use screening tests in all pregnant women. Especially that the only two pregnancies with Down syndrome in our study were under 35 years of age.

    Childhood leukaemias and lymphomas have been associated with exposure to environmental factors, including infections, which show geographical variation. This study examined the geographical distribution of the incidence of acute leukaemia and lymphoma using Manchester Children's Tumour Registry (MCTR) data 1976-2000. A total of 910 children were included, all of whom had histologically and/or cytologically verified leukaemia or lymphoma. At the time of their diagnoses, all the children were aged 0-14 years and were resident in the counties of Greater Manchester or Lancashire. Standardized morbidity ratios were calculated. Poisson regression was used to examine the relationship between incidence rates and small-area (census ward) population density, ethnic composition and deprivation index. There was a monotonic relationship between acute lymphoblastic leukaemia (ALL) incidence and population density (P = 0.05). Higher rates were seen in more densely populated areas. There was evidence for a monotonic relationship between the incidence of the mixed cellularity subtype of Hodgkin's disease (HD) and the Townsend deprivation score (P = 0.001). Markedly higher incidence was associated with greater levels of unemployment and household overcrowding. The results for ALL and mixed cellularity HD support the involvement of environmental factors, such as infections, in disease aetiology.

    Full Text Available Abstract Background Malaria is caused by protozoan parasites of the genus Plasmodium. It is one of the leading causes of illness and death in the world. It is a major public health problem in Ethiopia. Over the past years, the disease has been consistently reported as the first leading cause of outpatient visits, hospitalization and death in health facilities across the country. Methods A retrospective study was conducted to determine the prevalence of malaria from peripheral blood smear examinations from the Kola Diba Health Center of Ethiopia. The case notes of all malaria cases reported between 2002–2011 were carefully reviewed and analyzed. Additionally, any malaria intervention activities that had been taken to control malaria were collected using a well-prepared checklist from the study area. Results Within the last decade (2002–2011 a total of 59, 208 blood films were requested for malaria diagnosis in Kola Diba health center and 23,473 (39.6% microscopically confirmed malaria cases were reported in the town with a fluctuating trend. Regarding the identified plasmodium species, Plasmodium falciparum and Plasmodium vivax accounted for 75% and 25% of malaria morbidity, respectively. Malaria was reported in all age groups and both sexes, but the 15–44 year age group and males were more affected. Despite the apparent fluctuation of malaria trends in the area, the highest peak of malaria cases was reported during spring seasons. Conclusion Comparatively, after the introduction of the current malaria control strategies, the morbidity and mortality by malaria is decreasing but malaria is still a major health problem and the deadly species P. falciparium is predominant. Therefore, control activities should be continued in a strengthened manner in the study area considering both P. falciparium and P. vivax.

    Full Text Available In the summer of 2008–2009 species composition and quantity of macrozoobenthos in deposits samples collected with Ekman gripping device at 4 points of Starzyc Lake was studied. Lake Starzyc also called Chociwel is located in West Pomeranian Voivodeship and is adjacent to the town of Chociwel from South and South East of the city. In the collected material of the analysed lake macrozoobenthos organisms from the following classes were found: Oligochaeta, Hirudinea, Crustacea, Insecta and Bivalvia. The Insecta class was the most numerous one in respect of species found, including larvae of the following orders: Ephemeroptera (Leptophlebia sp., Ephemera sp., Caenis macrura (Stephens, Trichoptera (Limnephilidae, Leptoceridae, Cyrnus sp. Diptera and Megaloptera (Sialis lutaria L.. The density and biomass distribution in the analysed Starzyc Lake demonstrates the occurrence of unfavourable changes which may lead to eutrophication in the shallowest layers of the body reservoir and in the zone at the depth of 4.9 m. The littoral zone of the studied lake features high density and significant benthic fauna biomass with low values of PIE biodiversity index.

    The scaling relation and self similarity of earthquake process have been investigated by estimating the source parameters of 34 moderate size earthquakes (mb 3.4-5.8) occurred in the NW Himalaya. The spectral analysis of body waves of 217 accelerograms recorded at 48 sites have been carried out using in the present analysis. The Brune's ω-2 model has been adopted for this purpose. The average ratio of the P-wave corner frequency, fc(P), to the S-wave corner frequency, fc(S), has been found to be 1.39 with fc(P) > fc(S) for 90% of the events analyzed here. This implies the shift in the corner frequency in agreement with many other similar studies done for different regions. The static stress drop values for all the events analyzed here lie in the range 10-100 bars average stress drop value of the order of 43 ± 19 bars for the region. This suggests the likely estimate of the dynamic stress drop, which is 2-3 times the static stress drop, is in the range of about 80-120 bars. This suggests the relatively high seismic hazard in the NW Himalaya as high frequency strong ground motions are governed by the stress drop. The estimated values of stress drop do not show significant variation with seismic moment for the range 5 × 1014-2 × 1017 N m. This observation along with the cube root scaling of corner frequencies suggests the self similarity of the moderate size earthquakes in the region. The scaling relation between seismic moment and corner frequency Mo fc3 = 3.47 ×1016Nm /s3 estimated in the present study can be utilized to estimate the source dimension given the seismic moment of the earthquake for the hazard assessment. The present study puts the constrains on the important parameters stress drop and source dimension required for the synthesis of strong ground motion from the future expected earthquakes in the region. Therefore, the present study is useful for the seismic hazard and risk related studies for NW Himalaya.

    Full Text Available Abstract Background Malaria is a significant public health problem in Tanzania. Approximately 16 million malaria cases are reported every year and 100,000 to 125,000 deaths occur. Although most of Tanzania is endemic to malaria, epidemics occur in the highlands, notably in Kagera, a region that was subject to widespread malaria epidemics in 1997 and 1998. This study examined the relationship between climate and malaria incidence in Kagera with the aim of determining whether seasonal forecasts may assist in predicting malaria epidemics. Methods A regression analysis was performed on retrospective malaria and climatic data during each of the two annual malaria seasons to determine the climatic factors influencing malaria incidence. The ability of the DEMETER seasonal forecasting system in predicting the climatic anomalies associated with malaria epidemics was then assessed for each malaria season. Results It was found that malaria incidence is positively correlated with rainfall during the first season (Oct-Mar (R-squared = 0.73, p Conclusion These results demonstrate the potential of a seasonal forecasting system in the development of a malaria early warning system in Kagera region.

    Full Text Available Abstract Background There have been considerable changes in breastfeeding practices in China over the past forty years. However China is a very large country, and breastfeeding rates in different parts of China vary considerably. The objective of this paper is to identify and compare breastfeeding types and rates between 1994–1996 and 2003–2004 in Shihezi, Xinjiang Uygur Autonomous Region, PR China. Methods In 1994–1996, a study of breastfeeding (n = 2197 was undertaken in Shihezi, Xinjiang, PR China. A decade later in 2003–2004, a longitudinal study (n = 545 of infant feeding practices was undertaken in the same area. Results The 'any breastfeeding' rates at 1, 4 and 6 months were 94%, 82% and 78% respectively in the early 1990s. A decade later, breastfeeding at 1 month was lower, but rates at 4 and 6 months remained the same. In 2004 the 'full breastfeeding' rate at one month was significantly higher (57% than a decade earlier (38%, but after 3 months there was a rapid decline. This reflected a shift in the way complementary foods are introduced: the initial introduction was later, but by a higher proportion of mothers. Conclusion The rate of breastfeeding at one month is significantly lower in 2003–2004 when compared to 1994–1996. The 'full breastfeeding' rates were initially higher, but after 3 months were then lower. The Chinese national breastfeeding targets were not reached in either period of the study. These studies show the need to further promote full or exclusive breastfeeding and further longitudinal studies are necessary to provide the detailed knowledge about risk factors required for health promotion programs.

    To estimate prevalence of clinically-relevant intestinal nematodes in UK cats and dogs using the sensitive faecal analysis technique FLOTAC. Faecal samples were collected from 171 domestic dogs and 131 domestic cats living in urban areas of Lancashire and examined for the ova of intestinal parasites using the FLOTAC technique. All tested individuals were at least 6 months old, had not been treated with anthelmintics since 6 months of age nor in the 3 weeks prior to testing. In total, 5·3% of dogs (9/171) were positive for Toxocara canis; of these, 5/9 had dogs were positive for Uncinaria stenocephala, and 3 were positive for Strongyloides species. Single animals had Ancylostoma species and Spirocerca lupi infection. All egg counts were cats (34/131) were infected with Toxocara cati; of these, 6/34 had cats were positive for Strongyloides species, four for Ancylostoma species and single case for U. stenocephala, Toxascaris leonina and S. lupi. The high prevalence and zoonotic potential of Toxocara species in cats and dogs suggests the need for greater awareness of the need for repeated treatment. The discovery of S. lupi warrants further investigation and awareness of the clinical signs that this parasite may cause in cats and dogs. © 2016 British Small Animal Veterinary Association.

  7. Influence of Northwest Cloudbands on Southwest Australian Rainfall

    2014-01-01

    Full Text Available Northwest cloudbands are tropical-extratropical feature that crosses the Australian continent originating from Australia’s northwest coast and develops in a NW-SE orientation. In paper, atmospheric and oceanic reanalysis data (NCEP and Reynolds reconstructed sea surface temperature data were used to examine northwest cloudband activity across the Australian mainland. An index that reflected the monthly, seasonal, and interannual activity of northwest cloudbands between 1950 and 1999 was then created. Outgoing longwave radiation, total cloud cover, and latent heat flux data were used to determine the number of days when a mature northwest cloudband covered part of the Australian continent between April and October. Regional indices were created for site-specific investigations, especially of cloudband-related rainfall. High and low cloudband activity can affect the distribution of cloudbands and their related rainfall. In low cloudband activity seasons, cloudbands were mostly limited to the south and west Australian coasts. In high cloudband activity seasons, cloudbands penetrated farther inland, which increased the inland rainfall. A case study of the southwest Australian region demonstrated that, in a below average rainfall year, cloudband-related rainfall was limited to the coast. In an above average rainfall year, cloudband-related rainfall occurred further inland.

    Many glaciers along the southeast and northwest coast of Greenland have accelerated, increasing the Greenland ice sheet's (GrIS) contribution to global sea-level rise. Here, we map elevation changes in northwest Greenland during 2003-2009 using high-resolution Ice, Cloud and land Elevation Satellite (ICESat) laser altimeter data (Zwally, 2010) supplemented with altimeter surveys from NASA's Airborne Topographic Mapper (ATM) during 2002-2011 (Krabill, 2011). We use the measurements of elevation change to estimate catchment-wide ice volume loss (convert is to mass loss) and compare with independent measurements from GPS and the Gravity Recovery and Climate Experiment (GRACE) satellite gravity mission, launched in March, 2002. The GRACE results provide a direct measure of mass loss averaged over the entire northwest sector, while the GPS data are used to monitor crustal uplift caused by ice mass loss close to the sites. GPS data from a long term site at Thule Airbase show accelerated uplift starting in 2005 and a minor deceleration in 2009-2010. The deceleration is more dominant at GPS stations deployed in 2007 in northwest Greenland as part of the Greenland GPS Network (GNET). Independently, all three methods suggest increased ice loss in northwest Greenland starting in 2005 and a slowdown in 2009-2010.

    In 2008, the US Department of Energy’s (DOE) Wind and Water Power Program issued a funding opportunity announcement to establish university-led National Marine Renewable Energy Centers. Oregon State University and the University of Washington combined their capabilities in wave and tidal energy to establish the Northwest National Marine Renewable Energy Center, or NNMREC. NNMREC’s scope included research and testing in the following topic areas: • Advanced Wave Forecasting Technologies; • Device and Array Optimization; • Integrated and Standardized Test Facility Development; • Investigate the Compatibility of Marine Energy Technologies with Environment, Fisheries and other Marine Resources; • Increased Reliability and Survivability of Marine Energy Systems; • Collaboration/Optimization with Marine Renewable and Other Renewable Energy Resources. To support the last topic, the National Renewable Energy Laboratory (NREL) was brought onto the team, particularly to assist with testing protocols, grid integration, and testing instrumentation. NNMREC’s mission is to facilitate the development of marine energy technology, to inform regulatory and policy decisions, and to close key gaps in scientific understanding with a focus on workforce development. In this, NNMREC achieves DOE’s goals and objectives and remains aligned with the research and educational mission of universities. In 2012, DOE provided NNMREC an opportunity to propose an additional effort to begin work on a utility scale, grid connected wave energy test facility. That project, initially referred to as the Pacific Marine Energy Center, is now referred to as the Pacific Marine Energy Center South Energy Test Site (PMEC-SETS) and involves work directly toward establishing the facility, which will be in Newport Oregon, as well as supporting instrumentation for wave energy converter testing.

    Northwest Africa 5790, the latest nakhlite find, is composed of 58 vol.% augite, 6% olivine and 36% vitrophyric intercumulus material. Its petrology is comparable to previously discovered nakhlites but with key differences: (1) Augite cores display an unusual zoning between Mg# 54 and 60; (2) Olivine macrocrysts have a primary Fe-rich core composition (Mg# = 35); (3) The modal proportion of mesostasis is the highest ever described in a nakhlite; (4) It is the most magnetite-rich nakhlite, together with MIL 03346, and exhibits the least anisotropic fabric. Complex primary zoning in cumulus augite indicates resorption due to complex processes such as remobilization of former cumulates in a new magma batch. Textural relationships indicate unambiguously that olivine was growing around resorbed augite, and that olivine growth was continuous while pyroxene growth resumed at a final stage. Olivine core compositions (Mg# = 35) are out of equilibrium with the augite core compositions (Mg# 60-63) and with the previously inferred nakhlite parental magma (Mg# = 29). The presence of oscillatory zoning in olivine and augite precludes subsolidus diffusion that could have modified olivine compositions. NWA 5790 evidences at least two magma batches before eruption, with the implication that melt in equilibrium with augite cores was never in contact with olivine. Iddingsite is absent. Accordingly, the previous scenarios for nakhlite petrogenesis must be revised. The first primary parent magmas of nakhlites generated varied augite cumulates at depth (Mg# 66-60) as they differentiated to different extents. A subsequent more evolved magma batch entrained accumulated augite crystals to the surface where they were partly resorbed while olivine crystallized. Trace element variations indicate unambiguously that they represent consanguineous but different magma batches. The compositional differences among the various nakhlites suggest a number of successive lava flows. To account for all

    Since the Xingtai (邢台) earthquake in 1966, China Earthquake Administration has carried out a survey campaign along more than thirty deep seismic sounding (DSS) profiles altogether about twenty thousand kilometers long in North China to study the velocity structure of the crust and the upper mantle in this region, and has obtained a great number of research findings. However, these researches have not provided a 3D velocity structure model of the crust of North China and cannot provide seismic evidence for the study of the deep tectonic characteristics of the crust of the whole region. Hence, based on the information from the published data of the DSS profiles, we have chosen 14 profiles to obtain a 3D velocity structure model of North China using the vectorization function of the GIS software (Arc/Info) and the Kriging data gridding method. With this velocity structure model, we have drawn the following conclusions: (1) The P-wave velocity of the uppermost crust of North China changes dramatically, exhibiting a complicated velocity structure in plane view. It can be divided into three velocity zones mainly trending towards north-west. In the research area, the lowest-velocity zones overburden in the study area is somewhat inherited by the upper crust, there are still several differences between them. (2) Generally, the P-wave velocity of the crust increases with depth in the study area, but there still exists local velocity reversion. In the east, low-velocity anomalies of the Haihe eastern and western parts differ in structural trend of stratum above the crystalline basement. The Shanxi block and the eastern edge of the Ordos block is mainly north-west. (3) According to the morphological features of Moho, the crust of the study area can be divided into six blocks. In the Shanxi block, Moho apppears like a nearly south-north trending depression belt with a large crustal the Moho exhibits a feature of fold belt, trending nearly towards east-west. In the eastern

    We have recently described Eocene Tibetan Plateau remnants that are preserved as relict high-elevation, low-relief landscapes within the north-west Himalayan syntaxis (van der Beek et al., Nature Geosci., 2, 364-368, 2009). The recognition of these remnants is based on common morphologic characteristics and similar histories of long-term slow exhumation since at least 35 Myr ago. Here we extend our morphologic analysis to show that the Babusar area (Gamugah surface) and parts of the Northern Karakorum could constitute similar remnant Tibetan landscape elements. We also report additional thermochronology data from the Indus and Astor valleys that record the more recent incision history of the Deosai plateau borders (Northern Pakistan). Apatite fission-track and (U-Th)/He ages from the valleys are significantly younger (Nanga Parbat - Haramosh massif and toward the north, due to isostatic rebound. Inferred very low flexural rigidities for the region (effective elastic thickness ~3 km) are consistent with an overthickened fluid-bearing crust and with lower crustal flow from underneath the plateau toward the Nanga Parbat tectonic aneurism.

    Reconstructing centennial timescale hydroclimate variability during the late Holocene is critically important for understanding large-scale patterns of drought and their relationship with climate dynamics. We present sediment oxygen isotope records spanning the last two millennia from 10 lakes, as well as climate model simulations, indicating that the Little Ice Age was dry relative to the Medieval Climate Anomaly in much of the Pacific Northwest of North America. This pattern is consistent with observed associations between the El Niño Southern Oscillation (ENSO), the Northern Annular Mode and drought as well as with proxy-based reconstructions of Pacific ocean-atmosphere variations over the past 1000 years. The large amplitude of centennial variability indicated by the lake data suggests that regional hydroclimate is characterized by longer-term shifts in ENSO-like dynamics, and that an improved understanding of the centennial timescale relationship between external forcing and drought conditions is necessary for projecting future hydroclimatic conditions in western North America.

    Full Text Available This research was conducted in the framework of cultural geography — a relatively recent field of geography. This article considers the problems of geographical study of cultural landscapes of the North-West Russia, which includes Saint Petersburg, the Leningrad, Novgorod, Pskov, and Kaliningrad regions. This article sets out to develop and test the methodology for historical and cultural zoning at the mesogeographical level. The research and practical significance of the work lies in the identification of the features of formation of cultural landscapes in the North-West Russia, which can be used for the development of schemes of protection and rational management of territorial cultural and historical heritage. The authors rely on historical and cultural zoning as the basic geographical method of research on cultural landscapes. To this effect, the article offers a hierarchy of historical and cultural zones comparable to the zoning systems applied in physical, historical, and cultural geography. The major results of the research are the authors' taxonomy of historical and cultural complexes and the corresponding system of historical and cultural zoning of the North-West Russia presented on a sketch map. The article offers an exemplary description of historical and cultural provinces of the region. The contribution of the research to the Russian geography of culture is the authors' variant of taxonomy of historical and cultural complexes and the formulation of basic principles of historical and cultural zoning at different hierarchical levels. The research results can be applied, first of all, in the development of projects aimed at the protection and use of territorial cultural heritage in the framework of comprehensive schemes of territorial planning of the country's regions.

    Oxygen isotope (δ18O) measurements of authigenic carbonate from Cleland Lake (southeastern British Columbia), Paradise Lake (central British Columbia), and Lime Lake (eastern Washington) provide a ∼9000 year Holocene record of precipitation-evaporation balance variations in the Pacific Northwest. Both Cleland Lake and Paradise Lake are small, surficially closed-basin systems with no active inflows or outflows. Lime Lake is surficially open with a seasonally active overflow. Water isotope values from Cleland and Paradise plot along the local evaporation line, indicating that precipitation-evaporation balance is a strong influence on lake hydrology. In contrast, Lime Lake water isotope values plot on the local meteoric water line, signifying minimal influence by evaporation. To infer past hydrologic balance variations at a high temporal resolution, we sampled the Cleland, Paradise, and Lime Lake sediment cores at 1-60 mm intervals (∼3-33 years per sample on average) and measured the isotopic composition of fine-grained (ocean-atmosphere changes in the Pacific basin. Results from mid-Holocene (6000 yr BP) climate model simulations conducted as part of the Paleoclimate Modeling Intercomparison Project Phase 3 (PMIP3) indicate that in much of western North America, the cold season (October-March) was wetter and the warm season (April-September) was considerably drier relative to the late Holocene, leading to an overall drier climate in western North America with enhanced hydroclimatic seasonality. This is consistent with inferences from the Cleland and Paradise δ18O records, which lake modeling experiments indicate are strongly influenced by cold season precipitation-evaporation balance. This also explains apparent inconsistencies between the lake δ18O records and other proxies of hydroclimatic change from the greater Pacific Northwest region that are less sensitive to cold season climate and thus indicate relatively drier conditions during the mid-Holocene.

    The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to the 1981 regional power sales contracts. Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for inventory planning to determine BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The 1998 White Book is presented in two documents: (1) this summary of Federal system and Pacific Northwest region loads and resources; and (2) a technical appendix detailing the loads and resources for each major Pacific Northwest generating utility. This analysis updates the December 1997 Pacific Northwest Loads and Resources Study.

    Plant communities are the foundation for terrestrial trophic webs and animal habitat, and their structure and species composition are an integrated result of biological and physical drivers (Gates, 1993). Additionally, they have a major role in geologic, geomorphologic and soil development processes (Jenny, 1941; Stevens and Walker, 1970). Throughout most of the Pacific Northwest, environmental conditions support coniferous forests as the dominant vegetation type. In the face of anthropogenic climate change, forests have a global role as potential sinks for atmospheric carbon (Goodale and others, 2002). Consequently, knowledge of the status of forests in the three large parks of the NCCN [that is, Mount Rainier (MORA), North Cascades (NOCA), and Olympic (OLYM) National Parks] is fundamental to understanding the condition of Pacific Northwest ecosystems. Diverse climate and soil properties across the Pacific Northwest result in a variety of forest types (Franklin and Dyrness, 1973; Franklin and others, 1988; Henderson and others, 1989, 1992). The mountainous terrain of Mount Rainier, North Cascades, and Olympic National Parks create steep elevational and precipitation gradients within and among the parks: collectively, these parks span from sea level to more than 4,200 m; and include areas with precipitation from 90 to more than 500 cm. The resulting forests range from coastal rainforests with dense understories and massive trees draped with epiphytes; to areas with drought-adapted Ponderosa pines; to high-elevation subalpine fir forests interspersed with meadows just below treeline (table 1). These forests, in turn, are the foundation for other biotic communities constituting Pacific Northwest ecosystems.

    RTE (Reseau de Transport de l'Electricite) and GRTN (Gestore della Rete di Trasmissione Nazionale) are the transmission system operators respectively in France and in Italy. In the frame of the liberalization of the electricity market, the AEEG (Autorita per l'energia elettrica e il gas), and the CRE (the French regulatory authority) entered into an agreement on transfer capacity allocation over the Italian north west border (France-Italy and Switzerland-Italy borders) for the year 2004 ('the Agreement'). This allocation concerns the transfer capacity from France to Italy and from Switzerland to Italy autonomously allocable by Italy. This document summarizes the rules of the annual allocation mechanism for export capacities on the Italian northwest border for 2003: 1 - definitions; 2 - annual available capacity for the free market on the northwest border (reserved capacity, annual available capacity for the free market); 3 - annual allocation mechanism (prerequisite conditions, provisions for interruptible customer to participate to the annual allocation mechanism, provisions for eligible customers and traders to participate to the annual allocation mechanism, accuracy and completeness, nature, information about the user, annual allocation mechanism, capacity allocation confirmation, nomination of the annual allocated capacity and the reserved capacity, specific provisions related to the maintenance period on the France-Italy border, specific provisions related to the guarantee of the annual allocated capacity on the France-Italy border); 4 - general provisions (coming into force and duration of the rules, loss of the right to use the annual allocated capacity, guarantee prices and reimbursement, conditions of payment, force majeure, confidentiality, transfer of rights and obligations, notifications, contractual documents, responsibility, applicable law and language, dispute resolution).

    Full Text Available Leatherback sea turtles, Dermochelys coriacea, are highly migratory predators that feed exclusively on gelatinous zooplankton, thus playing a unique role in coastal and pelagic food webs. From 2007 to 2010, we used satellite telemetry to monitor the movements and dive behavior of nine adult and eleven subadult leatherbacks captured on the Northeast USA shelf and tracked throughout the Northwest Atlantic. Leatherback movements and environmental associations varied by oceanographic region, with slow, sinuous, area-restricted search behavior and shorter, shallower dives occurring in cool (median sea surface temperature: 18.4°C, productive (median chlorophyll a: 0.80 mg m(-3, shallow (median bathymetry: 57 m shelf habitat with strong sea surface temperature gradients (median SST gradient: 0.23°C km(-1 at temperate latitudes. Leatherbacks were highly aggregated in temperate shelf and slope waters during summer, early fall, and late spring and more widely dispersed in subtropical and tropical oceanic and neritic habitat during late fall, winter and early spring. We investigated the relationship of ecoregion, satellite-derived surface chlorophyll, satellite-derived sea surface temperature, SST gradient, chlorophyll gradient and bathymetry with leatherback search behavior using generalized linear mixed-effects models. The most well supported model showed that differences in leatherback search behavior were best explained by ecoregion and regional differences in bathymetry and SST. Within the Northwest Atlantic Shelves region, leatherbacks increased path sinuosity (i.e., looping movements with increasing SST, but this relationship reversed within the Gulf Stream region. Leatherbacks increased path sinuosity with decreasing water depth in temperate and tropical shelf habitats. This relationship is consistent with increasing epipelagic gelatinous zooplankton biomass with decreasing water depth, and bathymetry may be a key feature in identifying

    Full Text Available Introduction: Congenital heart diseases are of immense importance and also a high prevalence. Contributing factors to developing these defects have not been abundantly studied. Therefore, the current study was conducted aiming at determining the effective factors on Congenital Heart Disease (CHD in newborn infants of Northwest Iran. Methods: A case-control study was carried out in North-West of Iran from 2002 to 2012 and a total of 473 infants entered the study. Required data were obtained through check lists completed by the information of hospital records and interview with mothers of 267 newborn infants with CHD together with medical records of mothers as the case group, and 206 medical records of healthy infants at the same period all together with those of their mothers as the control group. The obtained data were statistically analyzed using descriptive statistical methods, T-test, Spearman’s correlation coefficient, and Multi-variable Logistic Regression Model (OR with 95% CI, using SPSS.19. In the present study, P value less than 0.05 was considered statistically significant. Results: Based on the results of univariable analyses, the number of previous cesarean sections, past medical history of diseases, gestational age (GA, fetal weight at birth, diastolic blood pressure, fetal heart rate, pulse rate, fetal hemoglobin and hematocrit levels, and fetal head circumference at birth have significant relationship with incidence of congenital abnormalities (P<0.05. Family history, past cesarean sections history, past medical history and GA had significant relationship with CHD incidence. Conclusion: Based on the results of present study, in order to control and reduce the cases of CHD, it is crucial to make proper decisions and implement policies for reducing cesarean cases, lowering consanguineous marriages, providing proper pre-marriage counseling, prompt treatment of mothers’ illnesses, improving pregnancy health care and mothers

  9. Energy and water consumption of Pacific Northwest irrigation systems

    1977-09-01

    Irrigation in the Pacific Northwest is an energy-intensive process which represents a major part of the total energy used in farm level food production. Since 1950, several major developments have precipitated pronounced increases in irrigation energy requirements. For example, the invention of efficient high-lift pumps, labor-saving equipment, new uses for irrigation sprinklers, and profitable cropping patterns have substantially escalated irrigation energy consumption in the Pacific Northwest in the past 25 years. Until recently, energy prices have remained relatively low and constant. The next 25 years will continue to experience advanced irrigation technologies. In addition to technological development, however, the cost of energy and water will certainly rise while their availabilities become increasingly constrained. The depletion of ground water in several parts of the United States could also potentially increase the irrigation burden of the Pacific Northwest. Lastly, parts of the Pacific Northwest water supply are directly convertible to energy via hydroelectric generation. This study proposes to make realistic projections relative to present and future interactions of the above components.

  6. The last frontier: catch records of white sharks (Carcharodon carcharias in the Northwest Pacific Ocean.

    Directory of Open Access Journals (Sweden)

    Heather M Christiansen

    Full Text Available White sharks are highly migratory apex predators, globally distributed in temperate, sub-tropical, and tropical waters. Knowledge of white shark biology and ecology has increased recently based on research at known aggregation sites in the Indian, Atlantic, and Northeast Pacific Oceans; however, few data are available for the Northwest Pacific Ocean. This study provides a meta-analysis of 240 observations of white sharks from the Northwest Pacific Ocean between 1951 and 2012. Records comprise reports of bycatch in commercial fisheries, media accounts, personal communications, and documentation of shark-human interactions from Russia (n = 8, Republic of Korea (22, Japan (129, China (32, Taiwan (45, Philippines (1 and Vietnam (3. Observations occurred in all months, excluding October-January in the north (Russia and Republic of Korea and July-August in the south (China, Taiwan, Philippines, and Vietnam. Population trend analysis indicated that the relative abundance of white sharks in the region has remained relatively stable, but parameterization of a 75% increase in observer effort found evidence of a minor decline since 2002. Reliably measured sharks ranged from 126-602 cm total length (TL and 16-2530 kg total weight. The largest shark in this study (602 cm TL represents the largest measured shark on record worldwide. For all countries combined the sex ratio was non-significantly biased towards females (1∶1.1; n = 113. Of 60 females examined, 11 were confirmed pregnant ranging from the beginning stages of pregnancy (egg cases to near term (140 cm TL embryos. On average, 6.0±2.2 embryos were found per litter (maximum of 10 and gestation period was estimated to be 20 months. These observations confirm that white sharks are present in the Northwest Pacific Ocean year-round. While acknowledging the difficulties of studying little known populations of a naturally low abundance species, these results highlight the need for dedicated

  7. Consequences of changes in vegetation and snow cover for climate feedbacks in Alaska and northwest Canada

    Changes in vegetation and snow cover may lead to feedbacks to climate through changes in surface albedo and energy fluxes between the land and atmosphere. In addition to these biogeophysical feedbacks, biogeochemical feedbacks associated with changes in carbon (C) storage in the vegetation and soils may also influence climate. Here, using a transient biogeographic model (ALFRESCO) and an ecosystem model (DOS-TEM), we quantified the biogeophysical feedbacks due to changes in vegetation and snow cover across continuous permafrost to non-permafrost ecosystems in Alaska and northwest Canada. We also computed the changes in carbon storage in this region to provide a general assessment of the direction of the biogeochemical feedback. We considered four ecoregions, or Landscape Conservations Cooperatives (LCCs; including the Arctic, North Pacific, Western Alaska, and Northwest Boreal). We examined the 90 year period from 2010 to 2099 using one future emission scenario (A1B), under outputs from two general circulation models (MPI-ECHAM5 and CCCMA-CGCM3.1). We found that changes in snow cover duration, including both the timing of snowmelt in the spring and snow return in the fall, provided the dominant positive biogeophysical feedback to climate across all LCCs, and was greater for the ECHAM (+3.1 W m-2 decade-1 regionally) compared to the CCCMA (+1.3 W m-2 decade-1 regionally) scenario due to an increase in loss of snow cover in the ECHAM scenario. The greatest overall negative feedback to climate from changes in vegetation cover was due to fire in spruce forests in the Northwest Boreal LCC and fire in shrub tundra in the Western LCC (-0.2 to -0.3 W m-2 decade-1). With the larger positive feedbacks associated with reductions in snow cover compared to the smaller negative feedbacks associated with shifts in vegetation, the feedback to climate warming was positive (total feedback of +2.7 W m-2 decade regionally in the ECHAM scenario compared to +0.76 W m-2 decade regionally

    The historical May-October mean temperature since 1831 was reconstructed based on tree-ring width of Qinghai spruce (Picea crassifolia Kom.) collected on Mt. Dongda, North of the Hexi Corridor in Northwest China. The regression model explained 46.6% of the variance of the instrumentally observed temperature. The cold periods in the reconstruction were 1831-1889, 1894-1901, 1908-1934 and 1950-1952, and the warm periods were 1890-1893, 1902-1907, 1935-1949 and 1953-2011. During the instrumental period (1951-2011), an obvious warming trend appeared in the last twenty years. The reconstruction displayed similar patterns to a temperature reconstruction from the east-central Tibetan Plateau at the inter-decadal timescale, indicating that the temperature reconstruction in this study was a reliable proxy for Northwest China. It was also found that the reconstruction series had good consistency with the Northern Hemisphere temperature at a decadal timescale. Multi-taper method spectral analysis detected some low- and high-frequency cycles (2.3-2.4-year, 2.8-year, 3.4-3.6-year, 5.0-year, 9.9-year and 27.0-year). Combining these cycles, the relationship of the low-frequency change with the Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO) and Southern Oscillation (SO) suggested that the reconstructed temperature variations may be related to large-scale atmospheric-oceanic variations. Major volcanic eruptions were partly reflected in the reconstructed temperatures after high-pass filtering; these events promoted anomalous cooling in this region. The results of this study not only provide new information for assessing the long-term temperature changes in the Hexi Corridor of Northwest China, but also further demonstrate the effects of large-scale atmospheric-oceanic circulation on climate change in Northwest China.

  12. Deep circulation in the northwest corner of the Pacific Ocean

    2001-04-01

    We deployed for two years a line of nine current-meter moorings bearing instruments at depths of 2, 3, and 4 km running southeast of Hokkaido, to measure currents above the continental slope, Kuril Trench, and Hokkaido Rise. The mean flow was directed southwestward above the continental slope, northeastward above the trench and upper rise (except at one mooring), and westward onto the lower rise. The mean currents were highly barotropic, except above the continental slope, and unexpectedly swift (8 cm s -1 in the trench). The velocity pattern above the Hokkaido Rise is like that observed earlier above the Aleutian Rise at Long. 175°W, and may be due, as suggested for the latter, to varying topographic beta associated with the curvature of the bottom profile of the rise. Thermal-wind fields from three CTD sections along the mooring line, while consistent among themselves, were unlike the observed mean shear, and therefore useless for estimating mean transports. Estimates based on the direct current measurements alone, for depths greater than 2000 m, are 4×10 6 m3 s-1 southwestward above the continental slope and 20×10 6 m3 s-1 northeastward in the trench; but the former might be too small, the latter too large, by as much as 10×10 6 m3 s-1 because of the relatively broad mooring spacing. These measurements, in combination with many others reported earlier, unequivocally describe swift deep southward flow along the inshore sides of the Izu-Ogasawara, Japan, and Kuril Trenches, and opposed flow along their offshore sides, as well as above their axes (except in the Izu-Ogasawara Trench). The southward flow may be, at least in part, the recirculation western-boundary current predicted for the northern North Pacific, although the oceanic geometry is different from, and more complicated than, that of the classic analytical predictive models. Reasons for the strong opposed flow are obscure. Water properties reveal that deep water spreads into the Izu-Ogasawara Trench

    2016-01-01

    The Intergovernmental Panel on Climate Change (IPCC) fifth assessment of projected global and regional ocean temperature change is based on global climate models that have coarse (˜100 km) ocean and atmosphere resolutions. In the Northwest Atlantic, the ensemble of global climate models has a warm bias in sea surface temperature due to a misrepresentation of the Gulf Stream position; thus, existing climate change projections are based on unrealistic regional ocean circulation. Here we compare simulations and an atmospheric CO2 doubling response from four global climate models of varying ocean and atmosphere resolution. We find that the highest resolution climate model (˜10 km ocean, ˜50 km atmosphere) resolves Northwest Atlantic circulation and water mass distribution most accurately. The CO2 doubling response from this model shows that upper-ocean (0-300 m) temperature in the Northwest Atlantic Shelf warms at a rate nearly twice as fast as the coarser models and nearly three times faster than the global average. This enhanced warming is accompanied by an increase in salinity due to a change in water mass distribution that is related to a retreat of the Labrador Current and a northerly shift of the Gulf Stream. Both observations and the climate model demonstrate a robust relationship between a weakening Atlantic Meridional Overturning Circulation (AMOC) and an increase in the proportion of Warm-Temperate Slope Water entering the Northwest Atlantic Shelf. Therefore, prior climate change projections for the Northwest Atlantic may be far too conservative. These results point to the need to improve simulations of basin and regional-scale ocean circulation.

    The strong warming and salinification of the Eastern North Atlantic starting in the mid 1990s has been attributed to a westward contraction of the subpolar gyre and stronger inflow of waters from the subtropical gyre. Temporal changes in the shape and strength of the two gyres have been related to the major mode of atmospheric variability in the Atlantic sector, the NAO. Hydrographic conditions along the Northwest European shelf are thus the result of different processes such as variations in transports, varying relative contributions of water masses from the two gyres and property trends in the source water masses. We examine the decadal variability in the eastern North Atlantic based on Argo data from 2000-2015 and have constructed time series for four water masses (Subpolar Mode Water (SPMW), Intermediate Water (IW), upper Labrador Sea Water (uLSW) and deep Labrador Sea Water (dLSW)) at selected locations along the Northwest European shelf. Data from the Rockall Trough and the Iceland Basin are chosen to represent advective pathways in the subpolar gyre at two major branches of the North Atlantic Current towards the Nordic Seas and the Arctic Ocean. Temporal variability of subtropical waters transported northward along the eastern boundary is studied at Goban Spur around 48°N. The Argo data are extended in time with long-term hydrographic observations such as the Extended Ellet Line data and other climatological sources in the region. For the study of transport fluctuations time series from the RACE (Regional circulation and Global change) program (2012-2015) and predecessor programs have been used. These programs have monitored the subpolar gyre in the western basin and provide time series of transports and hydrographic anomalies from moored instruments at the western flank of the Mid Atlantic Ridge (MAR). First results show that the temperatures and salinities remained at high levels for the upper waters (SPMW and IW) until 2010 and have been decreasing since

    Despite being in arid and semi-arid areas, erosion is largely a result of infrequent but heavy rainfall events; therefore,rainfall erosivity data can be used as an indicator of potential erosion risks. The purpose of this study was to investigate the spatial distribution of annual rainfall erosivity in North Jordan. A simplified procedure was used to correlate erosivity factor R values in both the universal soil loss equation (USLE) and the revised universal soil loss equation (RUSLE) with annual rainfall amount or modified Fournier index (Fmod). Pluviometric data recorded at 18 weather stations covering North Jordan were used to predict R values. The annual values of erosivity ranged between 86-779 MJ mm ha-1 h-1 year-1. The northwest regions of Jordan showed the highest annual erosivity values, while the northeastern regions showed the lowest annual erosivity values.

    The North Sea may be a mature play, but operators are continually searching for new ways to develop small finds near existing infrastructure and to develop discoveries in new areas at low cost. As they fill in gaps in the North Sea oil and gas infrastructure, companies are also exploring and planning developments in new plays such as the U.K.`s West of Shetlands area, the Irish Sea, and the Atlantic Margin from off western Ireland to northern Norway. Floating production systems and subsea technology are vital parts of many of Northwest Europe`s recently sanctioned field developments, for both large and small reservoirs. The paper discusses the dominant role of floating production units, the niche for subsea developments, new production, the Harding field, the Schieballion and Clair fields (UK), Norway`s plans, the Elgin/Franklin field, small fields, frontier work, in-field projects, flexible floating platforms, deepwater technology, a gas monotower, and subsea control.

    insse.ro/cms/rw/pages/index.ro.do in order to gather representative data on the evolution of national tourism for the 2009 – 2011, in each districts of North-West. The first part of the paper presents the foreign visitors who come to Romania, hence the largest number of foreign visitors and how it evolved from 2009 to 2011 the number of foreign tourists in Romania.The second part deals with the existing tourism potential in the North-West region and the opportunities offered by the region. The three part deals with the main touristic indicators in the six counties of North-West and the differences between them. The analysis is based on the comparison of main tourism indicators showing the tourist activity in the development regions of Romania, namely: the number of arrivals, number of nights and existing tourist capacity. The last part presents the steps that should be followed to overcome the losses caused by the crisis of 2008-2009 and to ensure a positive growth of the indicators analyzed.

    White-nose syndrome (WNS) is an emerging fungal disease of bats caused byPseudogymnoascus destructans. Since it was first detected near Albany, NY, in 2006, the fungus has spread across eastern North America, killing unprecedented numbers of hibernating bats. The devastating impacts of WNS on Nearctic bat species are attributed to the likely introduction ofP. destructans from Eurasia to naive host populations in eastern North America. Since 2006, the disease has spread in a gradual wavelike pattern consistent with introduction of the pathogen at a single location. Here, we describe the first detection of P. destructans in western North America in a little brown bat (Myotis lucifugus) from near Seattle, WA, far from the previously recognized geographic distribution of the fungus. Whole-genome sequencing and phylogenetic analyses indicated that the isolate of P. destructans from Washington grouped with other isolates of a presumed clonal lineage from the eastern United States. Thus, the occurrence of P. destructans in Washington does not likely represent a novel introduction of the fungus from Eurasia, and the lack of intensive surveillance in the western United States makes it difficult to interpret whether the occurrence of P. destructans in the Pacific Northwest is disjunct from that in eastern North America. Although there is uncertainty surrounding the impacts of WNS in the Pacific Northwest, the presence of the pathogen in western North America could have major consequences for bat conservation.

    Based on the daily turbulent heat fluxes and related meteorological variables dataeets (1985-2006) from Objectively Analyzed air-sea Fluxes (OAFlux) Project of Woods Hole Oceanographic Institution (WHOI), characteristics of low-frequency oscillation intensity of air-sea turbulent heat fluxes over the northwest Pacific are analyzed by linear perturbation method and correlation analysis. It can be concluded that: 1) the distribution of low-frequency oscillation intensity of latent heat flux (LHF) over the northwest Pacific is mainly affected by that of low-frequency oscillation intensity of anomalous air-eea humidity gradient (△q') as well as mean air-eea humidity gradient (△q), while the distribution of low-frequency oscillation Intensity of sensible heat flux (SHF) is mainly affected by that of low-frequency oscillation intensity of anomalous air-sea temperature gradient (△T'). 2) The low-frequency oscillation of turbulent heat fluxes over the northwest Pacific is the strongest in winter and the weakest in summer. And the seasonal transition of low-frequency oscillation intensity of LHF is jointly influenced by those of low-frequency oscillation intensity of △q', low-frequency oscillation intensity of anomalous wind speed (U'), △q and mean wind speed (U), while the seasonal transition of low-frequency oscillation intensity of SHF is mainly influenced by those of low-frequency oscillation Intensity of △T' and U. 3) Over the tropical west Pacific and sea areas north of 20ON, the low-frequency oscillation of LHF (SHF) is mainly influenced by atmospheric variables qa' (Ta') and U', indicating an oceanic response to overlying atmospheric forcing. In contrast, over the tropical eastern and central Pacific south of 20°N, qs' (Ts') also greatly influences the low-frequency oscillation of LHF (SHF).
