    Full Text Available Abstract Background Simulum damnosum Theobald sensu lato (s.l. is the vector of the parasitic filarial worm Onchocerca volvulus Leuckart which causes onchocerciasis. In order to understand the vector population dynamics, a preliminary 12 months entomological evaluation was carried out at Abeokuta, the Southwest Zone of Nigeria, an onchocerciasis endemic area, where vector control has not been previously initiated. S.damnosum s.l. flies were caught on human attractants between 700 to1800 hours each day, for 4 days each month, from August 2007 to July 2008. The flies caught were classified as either forest-dwelling or savanna-dwelling groups based on the colour of certain morphological characters. Climatic data such as rainfall, humidity and temperature were also collected monthly during the period of survey. Results A total of 1,139 flies were caught, 596 (52.33% were forest-dwelling group while 543 (47.67% were savanna-dwelling group of S. damnosum s.l. The highest percentage of forest-dwelling group was caught in the month of August 2007 (78.06% and the least percentage of forest-dwelling groups was caught in November 2007 (8.14%. The highest percentage of savannah-dwelling group was caught in the month of November 2007 (91.86% and the least percentage of savannah-dwelling group was caught in August 2007 (21.94%. There was no significant difference between the population of forest and savannah-dwelling groups of the fly when the means of the fly population were compared (P = 0.830. Spearman correlation analysis showed a significant relationship between monthly fly population with monthly average rainfall (r = 0.550, n = 12, P = 0.033, but no significant relationship with monthly average temperature (r = 0.291, n = 12, P = 0.179.

    2009-01-01

    Full Text Available This study reports the prevalence of malaria caused by plasmodium between genders in Abeokuta, the capital city of Ogun State located in the forest zone of southwestern Nigeria between January 2002 and December 2004. Blood film examination for malaria parasites in 708 patients; 366 males and 342 females. Microscopic examination of thick films techniques was employed for this study. Of the 708 (100% patients examined, 577 (81.5% were Plasmodium-positive. A high malaria parasite prevalence rate of 81.5% was noted in this study. Female subjects were more infected (42.4% than males (41.9% however, there was no significant difference in the sex of the subjects studied (p=0.05. A high malaria parasite prevalence rate of 86.9% was noted in samples collected in year 2003 than in other years studied. There was significant difference in the years under study (p=0.05. This study shows that a good percentage of people were infested by malaria Plasmodium. This could be attributed to lack of adequate accommodation and poor sanitary conditions in the area under study. Although several efforts have been made to effectively control the high incidence of malaria in Nigeria, these have been largely unsuccessful due to a number of reasons such as irrigated urban agriculture which can be the malaria vector’s breeding ground in the city, stagnant gutters and swamps in our environment where mosquitoes breed in millions, and lack of political will and commitment of the government in its disease management program, low awareness of the magnitude of malaria problem, poor health practices by individuals and communities and resistance to drugs. Therefore, future interventions in Nigeria should be directed toward controlling malaria in the context of a moderate transmission setting; thus, large-scale distribution of insecticide-treated nets or widespread use of indoor residual spraying may be less cost-effective than enhanced surveillance with effective case management or

    Multi-resistant Escherichia coli (E. coli) strains co-harboring virulence genes is a cause of high morbidity in Abeokuta, Nigeria. This study was designed to determine some virulent factors among enteropathogenic E. coli in Abeokuta, Nigeria. Approximately non-repetitive 102 isolates of E. coli were recovered from clinical samples from two health facilities in Abeokuta. Biotyping using API and antibiotic susceptibility was determined, and eae and flic genes were assayed by PCR. Antibiotic resistance relatedness was performed by DendroUPGMA. Results showed that 48.0% and 52.0 % were intestinal and extra-intestinal E. coli, ampicillin recorded 100% resistance, amoxycilli/clavulanic acid 64.7%, cotrimoxazole 57.8% and 56.8% resistance against cefotaxime, at MIC >16 ug/mL, 100%, 57.8%, and 50% have MIC50 to ampicillin, tetracycline, and ceftazidime, while 74.5% and 48.0% have MIC90 to ampicillin and ceftazidime. Significant rates of 4.9%, 7.8%, and 9.8% flic, eae, and flic/eae genes were found in intestinal isolates, while 2.9%, 2.0%, and 3.9% were found in extra-intestinal (P < 0.05). Two major clades of the resistant isolates reveal significant antibiotic relatedness among intestinal and extra-intestinal isolates, at 54% resistance similarities with very high multi-antibiotic resistance index of 1.0 (MARI). A high rate of undetected virulent E. coli pathotypes with high resistance could trigger unprecedented morbidity and mortality, mostly among children and the elderly. PMID:26263915

    Full Text Available The fast urban expansion has led to the transformation of the natural landscape into anthropogenic surfaces. The city of Abeokuta, for instance, is located in a region experiencing rapid urbanization, which has produced a remarkable effect on the surface thermal response. This effect significantly influences urban internal microclimatology on a regional scale. In this study, the surface temperatures and land cover types retrieved from Landsat TM and ETM+ images of Abeokuta city for 1984, 2003, and 2014 were analyzed. A quantitative approach was used to assess surface urban heat islands through the relationships among surface temperature and land cover types. Results showed that impervious surface areas were found to be correlated positively with high temperatures. Conversely, vegetated areas and bare surfaces correlated positively with mid temperature zones. This study found that areas with increasing impervious surfaces will accelerate LST rise and consequently lead to increasing effect of surface urban heat islands. These findings pose a major challenge to urban planners. However, the study would help to quantify the impacts of different scenarios (e.g., vegetation loss to accommodate urban growth on LST and consequently to devise appropriate policy measures.

  10. Temporal Variations in Radon and Meteorological Parameters in a Masonry Dwelling in Abeokuta, Nigeria

    Continuous hourly monitoring of radon activity concentrations was carried out in a masonry house in Abeokuta, Nigeria. Besides the radon activity concentrations, air temperature, relative humidity and barometric pressure were also recorded simultaneously on an hourly basis throughout the seven month exposure period, spanning June to December 2012. The average diurnal variation shows that 222Rn concentrations were high during the night and early morning hours and low during afternoon hours. The monthly averages of 222Rn concentration were in the range 19.9–53.5 Bq/m3, with an overall average of 32.3 Bq/m3. The indoor radon concentration correlates positively with the relative humidity (+0.4836) and negatively with both air temperature (−0.3757) and barometric pressure (−0.3463), while the daytime radon concentration and air temperature correlate positively (+0.5951).

    1997-09-01

    A survey of 612 black rats, Rattus rattus (282 mates and 330 females), for infections with helminth parasites was carried out in Abeokuta, in southwest Nigeria. Three hundred and ninety six (64.7%) were infected with one or more of seven species of helminths comprising three cestodes (Hymenolepis diminuta, Taenia taeniaeformis (cyst) and Raillietina sp.) three nematodes (Mastophorus muris, Trichuris muris and Syphacia sp.) and one acanthocephalan (Moniliformis moniliformis). Although the prevalence of infection in males (76.6%) was more than in females (54.5%) (P130 g (73.9%, MI=9.3). Moniliformis moniliformis was the most common species encountered (39.2%) and had the highest mean intensity in both sexes (x=7.4+/-0.74). Considering the rat-man proximity, this finding has considerable public health implications. PMID:9705679

  12. Economic burden of heart failure: investigating outpatient and inpatient costs in Abeokuta, Southwest Nigeria.

    Okechukwu S Ogah

    Full Text Available BACKGROUND: Heart failure (HF is a deadly, disabling and often costly syndrome world-wide. Unfortunately, there is a paucity of data describing its economic impact in sub Saharan Africa; a region in which the number of relatively younger cases will inevitably rise. METHODS: Heath economic data were extracted from a prospective HF registry in a tertiary hospital situated in Abeokuta, southwest Nigeria. Outpatient and inpatient costs were computed from a representative cohort of 239 HF cases including personnel, diagnostic and treatment resources used for their management over a 12-month period. Indirect costs were also calculated. The annual cost per person was then calculated. RESULTS: Mean age of the cohort was 58.0 ± 15.1 years and 53.1% were men. The total computed cost of care of HF in Abeokuta was 76, 288,845 Nigerian Naira (US$508, 595 translating to 319,200 Naira (US$2,128 US Dollars per patient per year. The total cost of in-patient care (46% of total health care expenditure was estimated as 34,996,477 Naira (about 301,230 US dollars. This comprised of 17,899,977 Naira- 50.9% ($US114,600 and 17,806,500 naira -49.1%($US118,710 for direct and in-direct costs respectively. Out-patient cost was estimated as 41,292,368 Naira ($US 275,282. The relatively high cost of outpatient care was largely due to cost of transportation for monthly follow up visits. Payments were mostly made through out-of-pocket spending. CONCLUSION: The economic burden of HF in Nigeria is particularly high considering, the relatively young age of affected cases, a minimum wage of 18,000 Naira ($US120 per month and considerable component of out-of-pocket spending for those affected. Health reforms designed to mitigate the individual to societal burden imposed by the syndrome are required.

    The larval habitats of mosquitoes were investigated in Abeokuta, Nigeria in order to determine the breeding sites of the existing mosquito fauna and its possible public health implications on the residents of the City. The habitats were sampled between August 2005 and July 2006 using plastic dippers and a pipette. The habitats were grouped as ground pools/ponds, gutters/open drains, tyres, domestic containers and treeholes/ leaf axils. Ten species of mosquitoes were encountered in the five habitats namely Mansonia africana, M. uniformis, Culex quinquefasciatus, Aedes aegypti, Ae. albopictus, Ae. vittatus, Cx tigripes, Anopheles gambiae s.l., An. funestus and Eretmapodite clnysogaster. Ae. aegypti bred in all the habitats sampled while Cx quinquefasciatus bred in four habitats except tree holes/leaf axils. An. gambiae s.l and Ae. albopictus occurred in three habitats while other species bred only in one or two habitats. Ground pools and domestic containers recorded the highest number of species followed by gutters/open drains. Tree holes/leaf axils was the least preferred habitat with the lowest number of species occurrence. However, statistical analysis revealed non-significant difference in species occurrence in the five habitats. The availability of the habitats to support the breeding of Aedes, Culex and Anopheles, which are known vectors of urban yellow fever, lymphatic filariasis and malaria suggest that the residents ofAbeokuta City are at risk of mosquito-borne diseases. It is important that residents of the City are enlighten on the environmental factors that contribute to mosquito breeding and that the Government should institute proper sanitation measures to reduce mosquito breeding sites.

Methods: Nonrepetitive E. coli isolates were collected from 202 subjects with or without evidence of diarrhea. Each isolate was biochemically identified and antimicrobial susceptibility testing was performed using the disk diffusion method. A sorbitol fermentation test of all the E. coli isolates was done and the minimum inhibitory concentration of suspected STEC was measured by the standard broth microdilution method to determine antibiotic resistance. The genotypes of stx1, stx2, and hlyA were determined by polymerase chain reaction assay. Results: The majority of subjects were aged ≥40 years (41.6% and were female (61.9%. Of the 202 subjects, 86.1% had STEC isolates (P<0.05. A high rate of STEC isolates resistant to amoxicillin (90.6%, cefotaxime (77.7%, and cefuroxime (75.7% was observed. Resistance to amoxicillin, gentamicin, and cefotaxime was demonstrated with a minimum inhibitory concentration >16 µg/mL in 13.9%, 11.4%, and 10.4% of the isolates, respectively. The prevalence of stx1, stx2, and hlyA was 13.9%, 6.9%, and 2.0%, respectively; 5.5% of

    Full Text Available Farm Practical programme addresses the short comings in curricular of agricultural graduates enabling them to acquire knowledge and practical skills needed to become proficient in agriculture. The study contributes in providing insights into perceptions of level 400 agricultural students regarding the Farm Practical Year (FPY programme at the University of Agriculture, Abeokuta, Nigeria. A total of 261 sample students were selected through stratified sampling procedure from 11 core agricultural departments and administered with pre-tested questionnaire. Results show that the programme provided students with ‘hands-on’ experience and opportunity to apply theory learnt in classroom to a real-life fi eld situation in which students had to adapt and solve problems on daily basis. Students also felt strongly that the farm practical would contribute to their professional career and employability on graduation. However, certain perceived problems were raised by students such as lack of on-campus accommodation, delay in payment of allowances and paucity of resources. It is recommended that greater efforts are needed to mentor students to take active interest in farm practical while human and material resources strengthened to deliver this mandate.

    2014-02-01

    Full Text Available Livestock production has become a common trend in urban communities whereby a number of people reared farm animals such as sheep and goats for social and economic reasons. Notwithstanding the associated advantages of livestock production, effective urban production of the small ruminants is greatly challenged by a number of factors. Based on this, the study was conducted with a view to identifying factors that challenged effective sheep and goat production in selected urban communities of Abeokuta, Ogun State. From the selected 12 urban communities where sheep and goats were reared, a total of 217 rearers were non-randomly selected using snow balling sampling method. A reliable and validated interview guide was used alongside field observation to obtain information on challenges to sheep and goats production in the urban areas. The results showed that the challenges were feed, health/disease, environmental, marketing and routine management related. All the respondents (100% experienced challenges such as high cost of feeding, theft of the farm animals, problem of off -season feeding and problem of sourcing feed variety for the animals. The chi-square test showed that a significant relationship exists between the respondents’ socioeconomic characteristics (sex: χ2 = 21.06, df =4; age: χ2 = 43.26, df = 16; education: χ2 = 78.09, df = 12; occupation: χ2 = 62.57, df = 16; income: χ2 = 56.35, df =16 and the encountered challenges (p

    Package manufacturers are now offering commercial-off-the-shelf column grid array (COTS CGA) packaging technologies in high-reliability versions. Understanding the process and quality assurance (QA) indicators for reliability are important for low-risk insertion of these advanced electronics packages. The previous reports, released in January of 2012 and January of 2013, presented package test data, assembly information, and reliability evaluation by thermal cycling for CGA packages with 1752, 1517, 1509, and 1272 inputs/outputs (I/Os) and 1-mm pitch. It presented the thermal cycling (-55C either 100C or 125C) test results for up to 200 cycles. This report presents up to 500 thermal cycles with quality assurance and failure analysis evaluation represented by optical photomicrographs, 2D real time X-ray images, dye-and-pry photomicrographs, and optical/scanning electron Microscopy (SEM) cross-sectional images. The report also presents assembly challenge using reflowing by either vapor phase or rework station of CGA and land grid array (LGA) versions of three high I/O packages both ceramic and plastic configuration. A new test vehicle was designed having high density interconnect (HDI) printed circuit board (PCB) with microvia-in-pad to accommodate both LGA packages as well as a large number of fine pitch ball grid arrays (BGAs). The LGAs either were assembled onto HDI PCB as an LGA or were solder paste print and reflow first to form solder dome on pads before assembly. Both plastic BGAs with 1156 I/O and ceramic LGAs were assembled. It also presented the X-ray inspection results as well as failures due to 200 thermal cycles. Lessons learned on assembly of ceramic LGAs are also presented.

    2016-04-01

    Land as a major collective human property faces a great deal of threats and eventual degradation from both natural and human causal factors across the globe. But for the central role of land in human's sustenance and quality living, man cannot afford to lose its natural asset and as such takes mitigating or remedial actions to save and restore his land for sustainable use. In view of this, the study assessed the causal factors of land degradation in urban areas of Abeokuta and effectiveness and sustainability of the taken remedial actions to stem the tide of land degradation in the study area. The selected communities were purposively selected based on the observed prevalence of degraded lands in the areas. A qualitative research approach which encompasses observational techniques - participant/field observation, interactive discussion and photographic capturing, was used for collection of data on land degradation in the study area. A combination of phenomenological, inductive thematic analysis and conversation/discourse analysis was employed for data analysis. The results showed land gradients/slopes, rainfall, run-offs/erosion, land-entrenched foot impacts, sand scraping/mining, poor/absence of drainage system and land covers as causal factors of land degradation in the study area. The employed remedial actions for restoration of degraded land included filling of drenches with sand bags, wood logs, bricks and stones, and sand filling. The study though observed that filling of drenches caused by erosion with rubles/stones and construction of drainage were effective remedial actions, good drainage system was presumed to be the most appropriate and sustainable remedial action for land restoration in the study area.

    2011-11-01

    Full Text Available This descriptive survey was carried out to investigate the level of knowledge on the predisposing factors to occupational hazards, among nurses in health facilities in Abeokuta, Ogun state, Nigeria. The study population consisted of nurses of varying categories working in ten public and two privately owned health facilities in five local government areas of the state. The simple random sampling technique was employed in selecting 1,200 respondents across the health facilities. A validated structured questionnaire developed with reliability of 0.79 was used to collect information. Data collected were analysed using the SPSS package version 12.0. The results revealed that 5.7% of the respondents were males, 94.3% were females, and 37.1% were single while 62.9% were married. Among the respondents, 44.8% were between 21-30 years of age, 15.2% between 31-40 years and 23.8% between 41-50 years while the remaining 16.2% were aged 51 years and above. Four hundred and sixty-nine (39.1% respondents have 1-10 years working experience while 60.9% have spent 11 years and above in the nursing profession. It was found that 96.2% of the respondents knew that the profession is prone to occupational hazards, and as expressed by 88.6% of the respondents, back injury is the commonest hazard, followed by neck and back pain as attested to by 84.8% of the nurses. The most prominent predisposing factor is prolonged standing as viewed by 84.5% of the sample. Avoidance of lifting of patients and heavy equipment, among others, is the most notable way of avoiding occupational hazards as attested to by 90.5% respondents. Nursing professionals should therefore make conscious and concerted efforts to minimize avoidable occupational hazards in the course of discharging their duties, so that their health would not be jeopardised.

    Full Text Available Problem statement: Pollution of well water, either from point or non-point sources, has become a thing of health concern both in urban and rural areas. Approach: This study aim at assessing the pollution hazards of groundwater resource by sampling some shallow wells from urban and peri-urban area of Abeokuta. Collected samples were analyzed for water quality parameters using standard procedures. The parameters determined were: Static water level, color, turbidity, temperature, Electrical Conductivity (EC, pH, Total Dissolved Solids (TDS Total Suspended Solids (TSS, Total Solids (TS, total hardness, cations {potassium (K sodium (Na, Calcium (Ca, magnesium (mg, Manganese (Mn, iron (Fe}, anions ﴾Chloride (Cl-, Nitrate (NO3, Sulphate (SO4, Phosphate (PO4}, heavy metals {lead (Pb, Zinc (Zn, Copper (Cu} and microbiological parameters {Bacteria count and Total Coliform count (TC}. Results: Results were subjected to statistical evaluations using SPSS 15.0 for descriptive statistics and Analysis Of Variance (ANOVA. The mean values of TDS, TS, EC and PO4 were higher in well water collected from urban areas compared to peri-urban areas during wet season. It was also observed that during the dry season, TDS, TSS, TS, EC, Mg, Fe, Cl-, PO4 and total hardness were also higher in samples collected from urban areas relative to peri-urban well water samples. Conclusion: Water quality parameters such as Fe, Pb, NO3, EC, Bacteria count and total coliform have mean values greater than World Health Organization maximum permissible standards for drinking water. Elevated values of these parameters are of great concern to public health when the water from these wells is consumed by people without treatment.

    Background: Upper arm composition is a reflection of body protein and calorie reserves. However, there is a paucity of data on upper arm composition of children from African countries, including Nigeria. This study aimed to determine the composition of upper arm and nutritional status of school children in Abeokuta, Nigeria and to compare with international reference standards. The sensitivity and specifi city of upper arm muscle area by height (UAMAH) as a nutritional assessment tool was also determined. Methods: Five hundred and seventy children aged 5 to 19 years were selected from seven schools using multistage random sampling. Weight, height, mid-upper arm circumference (MUAC) and triceps skin fold thickness (TSF) were measured. Body mass index, upper arm muscle area (UAMA), upper arm fat area (UAFA), fat percentage and UAMAH were derived. Results: The TSF, UAFA and fat percentage were significantly higher in females than males at each age group. MUAC and UAMA were significantly higher in female children aged 10-14 years, whereas UAMA was significantly higher in male children aged 15-19 years. UAMA and UAFA of the children were lower than those of Americans but similar to those of Zimbabweans, and higher than those of Indians. The sensitivity and specifi city of UAMAH for detecting wasting were 80.8% and 63.9%, respectively, whereas the corresponding values for stunting were 32.2% and 58.2%, respectively. Conclusions: The school children studied have a combination of poor calorie and protein reserve. UAMAH may be a valuable tool for complete evaluation of the nutritional status of school children.

    A survey was undertaken to determine the aflatoxin M(1) contamination of milk and some locally produced dairy products in Abeokuta and Odeda local governments of Ogun State, Nigeria. Samples of human and cow milk, yoghurt, "wara", ice cream and "nono" were collected randomly within the local governments and analysed for aflatoxin M(1) using the two-dimensional TLC. Aflatoxin M(1) contamination in the range of 2.04-4.00 microg l(-1) was noticed only in milk and ice cream. In particular, samples of human milk, cow milk and ice cream recorded high scores of 4.0 microg l(-1), 2.04 microg l(-1) and 2.23 microg l(-1), respectively in Abeokuta local governments and a score of 4.0 microg l(-1) for cow milk in Odeda local government. This indicates a high level contamination in the local governments since the weighted mean concentration of aflatoxin M1 in milk for African diet is 0.002 microg l(-1). Therefore the concentration of AFB1 in feeds which is transformed to AFM1 in milk should be reduced by good manufacturing and good storage practices. Furthermore, there is need for stringent quality control during processing and distribution of these products. PMID:17490709

  5. Reliability of CGA/LGA/HDI Package Board/Assembly (Revision A)

    Ghaffarian, Reza

    2013-01-01

    This follow-up report presents reliability test results conducted by thermal cycling of five CGA assemblies evaluated under two extreme cycle profiles, representative of use for high-reliability applications. The thermal cycles ranged from a low temperature of 55 C to maximum temperatures of either 100 C or 125 C with slow ramp-up rate (3 C/min) and dwell times of about 15 minutes at the two extremes. Optical photomicrographs that illustrate key inspection findings of up to 200 thermal cycles are presented. Other information presented include an evaluation of the integrity of capacitors on CGA substrate after thermal cycling as well as process evaluation for direct assembly of an LGA onto PCB. The qualification guidelines, which are based on the test results for CGA/LGA/HDI packages and board assemblies, will facilitate NASA projects' use of very dense and newly available FPGA area array packages with known reliably and mitigation risks, allowing greater processing power in a smaller board footprint and lower system weight.

    2010-06-01

    Full Text Available This study reports on the prevalence of typhoid fever between genders among patients in Abeokuta, Nigeria. Typhoid fever caused by Salmonella typhi is an endemic disease in the tropic and sub-tropic and has become a major public health problem in developing countries of the world with an estimated annual incidence of 540 per 100,000. The annual incidence of typhoid is estimated to be about 17 million cases worldwide. It is often encountered in tropical countries including Nigeria where they constitute serious sources of morbidities and mortalities. Blood samples were collected from 840 apparently healthy people; 460 (54.8% females and 380 (45.2% males. The samples were examined for the presence and levels of Salmonella typhi antibodies by Widal agglutination technique. The standard Samonella ‘O’ and ‘H’ suspension (ANTEC diagnostic products were used as antigens. Of the 840 sera tested, agglutinins to Salmonella typhi were most prevalent in female subjects accounting for [426(92.6%] of the ‘H’ antigens and [322(70.0%] of ‘O’ antigens at the various dilutions while in the male subjects, [351(92.4%] accounts for the ‘O��� and [327(86.1%] for the ‘H’ antigens. There was a female preponderance (F/M 2:1. The levels of agglutinin of Salmonella paratyphi C-H [93(24.5% ] and Salmonella typhi C-O [112(29.5%] in the males were however, low. In the females, the low significant agglutinin titres for Salmonella typhi O and Salmonella paratyphi A-O were observed in 27.6% and 36.1% of the sera respectively. The results of this study showed that more males had Salmonella agglutinin titres for S. typhi O [351(92.4%] and S. typhi H [327(86.1%]. More so, 132 (34.7% males had Salmonella agglutinin titres for S. paratyphi A-O, 119 (31.3% for S. paratyphi B-O, 112 (29.5% for S. paratyphi C-O, 117 (31.0% for S. paratyphi A-H, 125 (33.0% for S. paratyphi B-H, and 93 (24.5% for S. paratyphi C-H. It also showed that more females had Salmonella

  8. Evaluation of Immunity and Seropositivity of IgG Antibodies to Canine Parvoviruses in Vaccinated and Unvaccinated Dogs in Abeokuta, Nigeria.

    Babalola, E T; Ijaopo, O K; Okonko, I O

    2016-01-01

    Canine Parvovirus (CPV) is a very contagious and virulent viral disease affecting domestic dogs all over the world causing high morbidity and mortality in dogs, especially puppies. This study aimed at determining the seropositivity of IgG antibodies against CPV in vaccinated and unvaccinated dogs and to evaluate the immune status of dogs presented in Abeokuta. Forty-eight dogs were enrolled in this study. These dogs were presented at random for treatment, routine checkup, and vaccination at the State Veterinary Hospital and Veterinary Teaching Hospital all in Abeokuta. All the dogs were fully maintained under domestic setting. Selection for study was done based on thorough examination of the dogs and their medical records. The clients were informed of the nature of the investigation. Blood samples were collected and analyzed for anti-CPV-IgG. In principle, protective immunity correlates with high antibody titers and this was determined using a commercially available immunocomb® test kit for anti-CPV IgG antibody. Of 48 dogs sampled, 38 (79.2%) had high level of anti-CPV antibody titer and 10 (20.8%) had low level of anti-CPV antibody titer. Twenty six (54.2%) were males while 22 (45.8%) were females. Forty-five (93.75%) dogs were exotic breeds while 3 (6.25%) dogs were mongrels. Thirty (62.5%) of the dogs were less than one year old and the age range of all dogs sampled was between 7 weeks and 7 years. There was no significant difference (P > 0.05) between sex and the level of immunity but significant differences (P canine parvovirus among dogs in Abeokuta, Nigeria. Of all variables evaluated, ages of dogs, breeds and post-vaccination period were the main correlates of the level of immunity to CPV. This study also showed agreement with previous studies in the diagnostic value of using the immunoblot ELISA assay for the rapid detection of anti-CPV IgG antibody. PMID:25891124

  9. Association of cord blood des-acyl ghrelin with birth weight, and placental GHS-R1 receptor expression in SGA, AGA, and LGA newborns.

    González-Domínguez, Martha I; Lazo-de-la-Vega-Monroy, Maria-Luisa; Zaina, Silvio; Sabanero, Myrna; Daza-Benítez, Leonel; Malacara, Juan Manuel; Barbosa-Sabanero, Gloria

    2016-07-01

    Although ghrelin in cord blood has been associated to birth weight, its role in fetal and postnatal growth has not been elucidated. The aim of this study was to analyze total ghrelin, acyl ghrelin (AG), and des-acyl ghrelin (DAG) in cord blood of newborns with idiopathic birth weight alterations, and to evaluate protein expression of placental GHS-R1, in order to investigate their correlation with birth weight and placental weight. We performed a cross-sectional comparative study in umbilical cord blood and placentas from healthy mothers of SGA, AGA, and LGA (small, adequate and large for gestational age) term newborns (n = 20 per group). Cord blood total ghrelin, AG, and DAG were measured by ELISA, and placental GHS-R1 expression was evaluated by Western blot. Cord blood DAG was higher in SGA compared to AGA newborns (902.1 ± 109.1 and 597.4 ± 58.2 pg/ml, respectively, p = 0.01) while LGA and AGA showed similar values (627.2 ± 76.4 pg/ml for LGA, p = 0.80). DAG negatively correlated with birthweight (r = -0.31, p = 0.02) and placental weight (r = -0.33, p = 0.02). No differences in AG or total ghrelin were found. GHS-R1 protein in placenta was not differentially expressed among SGA, AGA, and LGA. Our results suggest a role of DAG in intrauterine growth. Further studies are needed in order to elucidate the mechanisms by which DAG participates in fetal growth. PMID:26754660

  10. Microbiological Assessment of Soil Contaminated with Refined Petroleum: A Case Study of Eluama in Isuikwuato LGA, Abia State, Nigeria

    Obiageli R. Ezeigbo

    2013-04-01

    Full Text Available A microbiological assessment of soil polluted by refined petroleum was carried out in Eluama community, Isuikwuato LGA, Abia State, Nigeria between March and October, 2012. The aim of the study is to examine the long-term kinetics of refined petroleum oil contaminated soil in this area from pipeline vandalization in the year 2000 and to assess the extent of biodegradation with respect to length of time of the spill. The microbiological examination of the soil samples were conducted by serial diluting and then inoculating the soil samples on different growth media. Several microbiological and biochemical methods were applied in order to isolate and identify the microorganisms accustomed to the soil sample. An unpolluted farmland served as control. Results showed a decrease in microbial load of soil as distance approaches seepage area. The control has a total heterotrophic bacteria count of 22.3 x 106 CFU/ml which decreases towards the seepage area (4.1 x 106 CFU/ml. The total fungi count also decreases from the control (5.9 x 106 CFU/ml towards the seepage area (1.2 x 106 CFU/ml. Micococcus sp and Pseudomonas aeroginosa were predominant in the seepage area up to 30m away from the seepage area. Other bacteria identified after this distance include Bacillus sp, Klebsiella pneumonia, Streptomyces sp, Streptococcus sp and Staphylococcus aureus while the predominant fungi were Aspergillus niger and Mucor sp. The marked decrease of heterotrophic bacteria and fungi in the petroleum polluted area compared with the control (the unpolluted farmland shows the unsuitability of the soil for agricultural purpose, as full remediation has not taken place.

  14. Seroprevalence of fowl pox antibody in indigenous chickens in jos north and South council areas of plateau state, Nigeria: implication for vector vaccine.

    Adebajo, Meseko Clement; Ademola, Shittu Ismail; Oluwaseun, Akinyede

    2012-01-01

    Fowl pox is a viral disease of domestic and wild birds. The large size of the genome makes it a useful vector for recombinant DNA technology. Although the disease has been described in both commercial and indigenous chickens in Nigeria, data are limited on seroprevalence in free range chickens. Such data are, however, important in the design and implementation of fowl pox virus vector vaccine. We surveyed current antibody status to fowl pox virus in free range chickens by testing 229 sera collected from 10 villages in Jos North and Jos South LGA of Plateau State Nigeria. Sera were analyzed by AGID against standard fowl pox antigen. Fifty-two of the 229 (23%) tested sera were positive for fowl pox virus antibody, and the log titre in all positive specimen was >2. Thirty (21%) and twenty-two (27%) of the samples from Jos South and Jos North, respectively, tested positive. This was, however, not statistically significant (P = 0.30). Generally the study showed a significant level of antibody to fowl pox virus in the study area. This observation may hinder effective use of fowl pox vectored viral vaccine. Fowl pox control is recommended to reduce natural burden of the disease. PMID:23762578

  16. North Korea drops out

    On March 12, North Korea announced that it was withdrawing from the Nuclear Non-Proliferation treaty (NPT). Soon afterward, it formally notified the U.N. Security Council of its intentions. The treaty remains binding on North Korea at least until mid-June, since a member must notify the Security Council and all other signatories three months in advance of withdrawing. This article explains North Korea's reasons for withdrawing, including reluctance to have the International Atomic Energy Agency (IAEA) conduct inspections of its nuclear waste sites. At press time, the US was leading an international effort to convince North Korea to reconsider its decision to withdraw from the NPT

    A lattice-gas Automata two-dimensional program was developed for analysis of single and two-phase flow behaviors, to support the development of integrated software modules for Nuclear Power Plant mechanistic simulations. The program has single-color, which includes FHP I, II, and III models, two-color (Immiscible lattice gas), and two-velocity methods including a gravity effect model. Parameter surveys have been performed for Karman vortex street, two-phase separation for understanding flow regimes, and natural circulation flow for demonstrating passive reactor safety due to the chimney structure vessel. In addition, lattice-Boltzmann Equation two-dimensional programs were also developed. For analyzing single-phase flow behavior, a lattice-Boltzmann-BGK program was developed, which has multi-block treatments. A Finite Differential lattice-Boltzmann Equation program of parallelized version was introduced to analyze boiling two-phase flow behaviors. Parameter surveys have been performed for backward facing flow, Karman vortex street, bent piping flow with/without obstacles for piping system applications, flow in the porous media for demonstrating porous debris coolability, Couette flow, and spinodal decomposition to understand basic phase separation mechanisms. Parallelization was completed by using a domain decomposition method for all of the programs. An increase in calculation speed of at least 25 times, by parallel processing on 32 processors, demonstrated high parallelization efficiency. Application fields for microscopic model simulation to hypothetical severe conditions in large plants were also discussed.

    Proliferation has become an important political issue over the last decades, marked simultaneously by the nuclearization of South Asia, the strengthening of international regimes (TNP, CW, MTCR) and the discovery of fraud and trafficking. This paper presents the motivations and strategy of North Korea in violating existing agreements and developing an alternative source of weapons grade material. Then it analyses the US gradual economical and political strategy to pressure North Korea to eliminate its nuclear weapons program. The future position of the US will depend on the Iraq outcome and on the results of its pressure policy on North Korea. (J.S.)

  5. North Korea's corroding fuel

    The roughly 8,000 irradiated or open-quotes spentclose quotes fuel rods recently discharged from the North Korean 25 megawatt (thermal) reactor are difficult to store safely under the conditions in the spent fuel ponds near the reactor. The magnesium alloy jacket, or open-quotes cladding,close quotes around the fuel elements is corroding. If the corrosion creates holes in the cladding, radionuclides may be released. In addition, the uranium metal underneath the cladding may begin to corrode, possibly creating uranium hydride which can spontaneously ignite in air. Unless the storage conditions are improved, North Korea may use the risk posed by the corrosion as an argument for reprocessing this fuel, a violation of its June 1994 pledge to the United States to freeze its nuclear program. North Korea, however, can take several steps to slow dramatically the rate of corrosion. Using available techniques, it can extend safe storage times by months or even years

  6. North Korea, Quo Vadis?

    Karl H. Stingeder

    2014-03-01

    Full Text Available North Korean politics appears neither irrational nor unpredictable: the logic of its actions may at first seem opaque, but it nonetheless displays its own rationale and patterns. – North Korea: a ruthless political actor, now under the leadership of Kim Jong-Un who inherited the regime’s leadership from his father and "Supreme Leader", Kim Jong-Il, in 2011. The country’s policy is based on its ongoing political agenda of (nuclear brinkmanship, a true threat to the world – or at least that's how the Western hemisphere sees it. Yet our factual knowledge of this post-Leninist and totalitarian regime is extremely limited and relatively distorted; it is largely circumstantial evidence and judgmental speculation that accounts for our perception of this East Asian state. Northeast Asia (China, Japan, South and North Korea, Taiwan is a region dominated by the legacy of the Cold War. The North Korean leadership has indeed established its priorities, primarily its isolationist orientation, but in the long term the regime cannot survive without external stimulus. Most importantly, even in a long-term, non-violent and gradual transformation of North Korea considerable danger can ultimately result in the demise of the regime. Apart from few signs of a North Korean "civil society", currently only the army might have the resources to see through a regime change. In the meantime, the strategies of isolationism as well as tight control of the media remain as fundamental cornerstones of the regime. A close-knit network of social control has been established and access to the internet for the most part is limited to the regime’s entrusted cadre.

  7. Moving farther north

    According to predictions by the National Petroleum Council, North American demand for natural gas is likely to increase from 20 Tcf currently to 29 Tcf by the year 2010 and could increase to beyond 31 Tcf by 2015. In view of this and other similar predictions it is prudent to examine the potential sources of supply and to assess their capacity to meet this ever increasing demand. This paper provides an overview of North America's gas potential, proved reserves and current production. One of the sources much depended upon to meet future demand is the deepwater Gulf of Mexico which, however, would have to grow at the compounded rate of 21 per cent annually to meet expectations of 4.5 Tcf per year by 2010, a staggering rate of growth that would require 250 to 300 completions per year (current rate is about 100 per year) and two to three times the number of rigs currently working in the Gulf. If the deepwater Gulf of Mexico cannot meet this target, the incremental supply will most likely come from the North, namely the Fort Liard, Norman Wells, and the Mackenzie Delta/Beaufort Sea regions of Canada and Alaska's Cook Inlet, Copper River, North Slope and Susitna Basin. The economics of developing each of these regions is examined, using field size, reserves per well, exploration and development costs and cycle time as the bases for comparison. Obstacles to development such as access to pipelines, government regulations, and opposition by environmental groups are also discussed

  10. Lignite in North Dakota

    The State of North Dakota and the lignite industry are working together in a partnership called the Lignite Research, Development and Marketing Program. The program provides funds and supports activities which: preserve and enhance jobs and lignite production; ensure economic growth, stability and opportunity; and maintain a stable and competitive tax base. Since 1987, 70 grants totaling $24 million have been awarded. Each program dollar has resulted in nearly five of matching dollars. These program investments have yielded returns for the state and industry, including an additional $20 million annually from by-products at the Great Plains Synfuels Plant; about $1 million annually from improved reclamation practices; and combustion options, which preserve 2,000 megawatts of existing generation capacity. Research activities have identified future opportunities, including: the SynCoal demonstration plant, requiring 800,000 tons per year of new production; new chemical feedstock by-products from Great Plains worth an additional $26 million annually; revised reclamation practices that could substantially reduce cost; and potential new markets for upgraded lignite of about 12 million tons annually. This program helps ensure a healthy future for the North Dakota lignite industry, which currently represents 10% of the state's total economic base. Such a program is important because it will encourage the development of new and better uses of North Dakota's most abundant resource--lignite coal

    2007-11-15

    North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City. The third forum (Energy Diversification) was hosted in Halifax, Nova Scotia.

  12. Anaglyph, North America

    2003-01-01

    This anaglyph (stereoscopic view) of North America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south and 736 meters east-west in central North America), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the North American continent is readily apparent.Active tectonics (structural deformation of the Earth's crust) along and near the Pacific North American plate boundary creates the great topographic relief seen along the Pacific coast. Earth's crustal plates converge in southern Mexico and in the northwest United States, melting the crust and producing volcanic cones. Along the California coast, the plates are sliding laterally past each other, producing a pattern of slices within the San Andreas fault system. And, where the plates are diverging, the crust appears torn apart as one huge tear along the Gulf of California (northwest Mexico), and as the several fractures comprising the Basin and Range province (in and around Nevada).Across the Great Plains, erosional patterns dominate, with stream channels surrounding and penetrating the remnants of older smooth slopes east of the Rocky Mountains. This same erosion process is exposing the bedrock structural patterns of the Black Hills in South Dakota and the Ozark Mountains in Arkansas.

    Remarks by the Deputy Assistant Secretary for International Energy Cooperation concerning North American energy policy were presented. Guiding principles behind the National Energy Policy report released in 2001 were presented, stressing energy and economic security for the United States as well as strengthening global energy security, particularly in the western hemisphere. The energy trade relationship between Canada and the United States was discussed along with economic integration, with particular reference to the northeastern provinces of Canada. An overview of growth in offshore oil production, crude oil and petroleum exports from Canada was examined. American gas consumption levels and a forecast for future economic developments between the two countries was outlined. Four major orders were presented to contextualize future trade relationships: the authorizing of Presidential permits for petroleum and liquids pipelines that cross international boundaries of the United States; the signing of a Memorandum of Understanding between the Canadian National Energy Board (NEB) and the US Federal Energy Regulatory Commission (FERC) addressing the sharing of information between the two organizations; the signing of the Canada-United States Critical Infrastructure Protection (CIP) Framework for Cooperation; and, the United States-Canada Power System Outage Task Force report. The goals, challenges and obstacles of the North American Energy Working Group (NAEWG) were also outlined, with specific reference to their principal objective of promoting a more fully integrated energy market in North America. An outline of future initiatives planned by the Bush Administration was presented, including details of the International Partnership for the Hydrogen Economy and the international Carbon Sequestration Leadership Forum and outlines of the Western Hemisphere Energy Technology Cooperation Initiative. It was concluded that the partnership between Canada and the United States

  14. Apollo in the North

    Østermark-Johansen, Lene

    2015-01-01

    Walter Pater’s fascination with the Hyperborean Apollo, who according to myth resided north of the home of the northern wind, is explored in two of his pieces of short fiction, ‘Duke Carl of Rosenmold’ (1887) and ‘Apollo in Picardy’ (1893). The essay discusses some of Pater’s complex dialogue wit......: where does it begin? Where does it end? Is it a place of light or of darkness? Pater’s dark Apollo challenges conventional notions of the sun god and testifies to the strong presence of paganism in Pater’s late writings....

    ABSTRACT: The construction boom in North Cyprus, followed by Annan Plan, have resulted in the construction of a great number of buildings with minimum costs and quality. Although there exist certain rules for the construction of new buildings in North Cyprus, and part of these rules are related to the roofs, defects are observed few years after construction. This thesis intends to introduce different roof systems in North Cyprus, to find their problems and suggest solutions. In this respe...

  17. Energy policy of North Korea

    Since the year 1990, North Korea suffers internal-policy problems as well as foreign-political problems. The gross domestic investment decreased by 3.8% yearly between the years 1990 and 1998. Many actual problems of North Korea correspond with the energy crisis in this land affecting nearly all sectors of economy and society. This energy crisis was released by the fact, that the former Soviet Union has stopped the supply of primary energy in the year 1991. In the contribution under consideration, the author reports on the energy policy of North Korea. The main themes of this contribution are: (a) Development and characteristics of the energy sector; (b) Crisis of the energy sector; (c) Consequences of the energy crisis in North Korea; (d) Possibilities of the solution of the energy crisis. For the U.S.A. and the international community, the energy crisis offers the possibility to turn North Korea to negotiations by means of remedial measures in the energy sector. In response, North Korea should drop its nuclear energy program. Apart from such positive incentives, the threat of sanctions is conceivable. North Korea imports nearly 70 % of its oil demand from the People's Republic of China. Therefore, China has an great influence on North Korea. The energy crisis of North Korea shows the fatal consequences of a falsely performed energy policy with respect to the population of this land and with respect to the stability and disposing capacity of the political leadership

  18. North Central Thailand

    1998-01-01

    This radar image shows the dramatic landscape in the Phang Hoei Range of north central Thailand, about 40 kilometers (25 miles) northeast of the city of Lom Sak. The plateau, shown in green to the left of center, is the area of Phu Kradung National Park. This plateau is a remnant of a once larger plateau, another portion of which is seen along the right side of the image. The plateaus have been dissected by water erosion over thousands of years. Forest areas appear green on the image; agricultural areas and settlements appear as red and blue. North is toward the lower right. The area shown is 38 by 50 kilometers (24 by 31 miles) and is centered at 16.96 degrees north latitude, 101.67 degrees east longitude. Colors are assigned to different radar frequencies and polarizations as follows: red is L-band horizontally transmitted and horizontally received; green is L-band horizontally transmitted and vertically received; blue is C-band horizontally transmitted and vertically received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture (SIR-C/X-SAR) imaging radar on October 3, 1994, when it flew aboard the space shuttle Endeavour. SIR-C/X-SAR is a joint mission of the U.S./German and Italian space agencies.Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA

  20. Propane: North American opportunities

    Opportunities for expanding the propane market in North America are discussed. The goal of change should be to enhance client satisfaction and loyalty. The current customer base is largely comprised of pick-up trucks, vans and buses in commercial fleet service, police and similar fleet service and privately owned vehicles. Opportunities for the expansion of propane exist due to: vehicles being kept and lasting longer, allowing a longer pay-back time; exhaust emission standards becoming more stringent; the possible introduction of emission standards for substances currently not controlled; and properly combusted CO2 emissions that are at least 12% lower than gasoline. The continuing development of engine fuel management systems, application of extensive road/highway experience, matching supply and refuelling infrastructure to consumer demands, application in air quality non-attainment areas, and original equipment manufacturer, government and industry cooperation are discussed. 8 figs

  3. The North Pacific Gyre Mode

    Schneider, N.; di Lorenzo, E.

    2007-12-01

    Discussion of North Pacific Decadal decadal variability has focused primarily on the Pacific Decadal Oscillation, the leading mode of sea surface temperature anomalies north of the tropics. The PDO appears to result from a superposition of SST pattern forced by the North Pacific atmosphere due to its intrinsic dynamics and teleconnected from the tropics, with a regional impact of the ocean circulation in the frontal regions associated with the Kuroshio/Oyashio and their extensions into the interior. Recent modeling, however, suggest that previously unexplained decadal changes of salinity, nutrient upwelling and chlorophyl in the California Current are not dominated by the PDO. Rather, these are associated with a mode of variability associated with wind driven changes of the North Pacific Gyre. Consideration of this mode variability may thus be important to understand present and future variations of the North Pacific ecosystem, and in the interpretation of climate proxies.

  4. North Korea: a mercenary proliferator?

    After having recalled that North Korea possesses a rather advanced ballistic programme which has been started in the 1970 with the Chinese support, that North Korea is the fourth world producer of ballistic missiles, the author outlines that this country has become a major proliferator as it exports this production to different States and non-State actors. He recalls the long history of relationships between North Korea and terrorist organisations (even during the Cold War), comments the current and major support of North Korea to Hamas and Hezbollah in Gaza and in Lebanon. These relationships are then related with those these both organisations have with Syria and Iran who are in fact the relays between them and North Korea. The author explains why Hamas and Hezbollah must buy their weapons to such a far country: Iran is submitted to international sanctions, Iran and Syria want to avoid being banned from the international community for selling weapon to a terrorist (or so-said) organisation, and prices are rather competitive. If North Korea is also submitted to international sanctions, weapon smuggling seems to be institutional in this country. The author finally briefly evokes the issue of chemical weapons: North Korea possesses few thousand tonnes of these weapons, and could export them to non-state organisations

    An understanding of the relationship of economic growth and potential petroleum product demand is needed to forecast the potential for North American oil demand growth as well as knowledge of world supply and price. The bullish expectations for economic growth in the US and Canada auger well for North American refiners and marketeers. The growth in world economic output forecast, however, means a larger oil demand and an increase in OPEC`s pricing power. Such price increases could depress North American oil demand growth.

  7. Advantages of North Sea Assets

    The North Sea is a significant hydrocarbon province and any large multinational will need to maintain North Sea assets within their portfolio - as indeed they do. The general feeling that pervades the oil industry that the North Sea is ''mature'' can be demonstrated by reference to the facts. The result is a potential fall-off in activity and a serious threat to the future levels of profitability in the region. Notwithstanding the continuing development of large fields, such as Troll, of or multi-field developments, for example BP's recent announcement on ETAPs, activity is beginning to fall, most noticeably at the front end of the development cycle, in exploration.

  8. Famine in North Korea Redux?

  9. Blogging from North Pond

    Marziali, C. G.; Edwards, K. J.

    2009-12-01

    Sea going research expeditions provide an ideal opportunity for outreach through blogs: the finite duration limits the author's commitment; scientists are usually in a remote location with fewer distractions; and fieldwork is visual and interesting to describe. Over four weeks this winter, Katrina Edwards of USC authored a blog about her deep-sea drilling expedition to North Pond, a depression in the ocean crust in the mid-Atlantic. She emailed daily dispatches and photos to USC Media Relations, which maintained a (still accessible) blog. Written for the general public, the blog quickly attracted interest from lay readers as well as from media organizations. Scientific American carried the blog on its web site, and the National Science Foundation linked to it in its "Science 360" electronic news digest. The blog also led to a Q&A with Edwards in the widely-read "Behind the Scenes" feature of LiveScience. Interest from science bloggers and National Geographic towards the end suggests that the blog could have expanded its reach given more time: expeditions lasting between six weeks and three months, such as occur during ocean drilling expeditions, would appear to be ideal candidates for a blog. Most importantly, the blog educated readers about the importance to planetary life of what Edwards calls the "intraterrestrials": the countless microbes that inhabit the oceanic crust and influence major chemical and biological cycles. Considering that the subjects of the expedition were invisible critters in a pitch-dark place, the blog shows what can be accomplished by scientists and institutions committed to public outreach.

  14. The North Dakota lignite partnership

    The State of North Dakota and the Lignite Energy Council have formed a government/industry partnership to promote the use of North Dakota lignite. The partnership provides funding and management for the Lignite Research, Development and Marketing Program. The program funds activities which preserve and enhance jobs and lignite production; ensure economic growth, stability and opportunity; and maintain a stable and competitive tax base. Funding is provided for activities in three areas: marketing feasibility studies, small research projects, and demonstration projects. Funding is derived from the state coal severance tax. Approximately $3,000,000 annually is appropriated from coal severance revenues for program activities. North Dakota is the ninth largest coal producing state, with lignite as the only rank of coal found in the state. Energy is the second largest economic sector in North Dakota, and it currently comprises over 12% of the state's total economic base. This paper reviews the North Dakota lignite industry and describes studies and projects which have received funding from the program

  15. The effects of regional economic integration in Europe of the pattern north-north and north-south

    Antevski Miroslav

    2007-01-01

    Full Text Available This paper examines the effects of regional economic integration in Europe, especially the North-North and North-South integration patterns, and how the benefits and costs of integration are divided between countries. Outcomes depend on: comparative advantages, factor endowments, factor intensities, competitive advantages, FDI flows, transfers of technology, knowledge spillovers, economies of scale, transport costs, industry/GDP ratios, and agglomeration forces. The North-North integration between high income countries tends to lead to convergence of country incomes. Contrary, the South-South integration between low income countries causes divergence. Low income countries are likely to be better served by the North-South integration.

    2016-12-01

    Full Text Available The need to use palm surface area (PSA in ergonomics, burn therapy, thermal physiology, and medicine necessitated the studies on its determination. The purpose of this study was to determine the PSA of students in a tertiary institution in Nigeria, propose a model to obtain the PSA, and use the neural network to reflect the effects of age, height, and weight on PSA. A total of 400 students comprising of 185 male and 215 female students aged between 16- and 25-years old were used for the study. Nonlinear regression analysis on SPSS 16.0 statistical package was used to extract the best fit correlation for Nigerian students with PSA as the dependent variable; and height, weight, and age as independent variables. The neural network on SPSS 16.0 was used to design the multilayer perceptron to predict PSA using age, height, and weight of the students. The estimated values using the models were not statistically different from the obtained values from the study (p = 0.000. The prediction of PSA showed that the neural network can be trained with almost no significant error of the output and that there was a nonlinear relationship between the input and output variables.

    The North West Shelf Venture is based in Karratha, 1500 km north of Perth in Western Australia. At a cost of $A12bn, it is the biggest and one of the most important natural resource developments in Australia. Originally constructed in 1984 to supply gas to the West Australian domestic and industrial market, the Venture is now the third-largest LNG exporter in the Asia-Pacific region, generating more than $A1.5bn a year in export income. The Venture supplies about 15 percent of Japan's LNG demand, or 7.5 million tonnes a year, to eight Japanese power and gas utilities under 20-year contracts. In addition, 'spot' sales have been made to Spain, South Korea, Turkey and the United States. The Venture also supplies more than 70 percent of Western Australia's domestic gas requirements and exports LPG, condensate and crude oil to global markets

  9. Radioactivity in the North Sea

    This chapter lists the main sources of radioactivity in the North Sea and explains the units used. The main source is naturally occuring long-lived radionuclides. Other significant sources are the Sellafield reprocessing plant, atmospheric atomic weapons testing, fallout from the Chernobyl reactor accident, the French nuclear reprocessing plant at Cap la Hague and oilfield production water brines. However, currently these are not significant compared with the natural background. If this is to continue, lower levels of discharge into the sea, strict control of new discharges and the cessation of atmospheric nuclear tests will be needed. There is a map showing the concentration of Cs137 in filtered water from the North Sea in 1985. (UK)

  12. North American oil demand outlook

    The forecasting of future demand for petroleum and petroleum products in North America is discussed, with reference to oil prices, oil supplies, and economic growth. Annual North American economic growth is expected to be in the 2.5-3.5% range, while outside of North America, world economic output is forecast to grow 3.7% in 1995, over double the average of the past four years. A substantial growth in world oil demand that may result from this growth seems likely to increase the pricing power of OPEC; this will likely increase oil prices, which in turn will depress oil demand growth, particularly in North America. If oil consumption rises 2.5%/y over the next decade, demand for OPEC oil should increase by ca 13 million bbl/d. There is little doubt that OPEC could increase production by that much, but there is a question whether they will do so without at current or near-current prices. Since this is felt to be rather unlikely, it is thus probable that oil prices will rise substantially during the next decade. This will be followed by a decline in prices as OPEC's pricing power is weakened by competition from conservation and non-OPEC supply. Petroleum consumption in the USA is forecast to rise slowly over the next 2-3 y but a decline will set in by 2000. Motor gasoline consumption is forecast to fall from its current level of ca 7.6 million bbl/d to ca 7.45 million bbl/d by 2005 before recovering in the face of lower prices. 3 figs., 3 tabs

    Full Text Available An international workshop entitled “GONAF: A deep Geophysical Observatory at the North Anatolian Fault”, was held 23–27 April 2007 in Istanbul, Turkey. The aim of this workshop was to refine plans for a deep drilling project at the North Anatolian Fault Zone (NAFZ in northwestern Turkey. The current drilling target is located in the Marmara Sea offshore the megacity of Istanbul in the direct vicinity of the main branch of the North Anatolian Fault on the PrinceIslands (Figs. 1 and 2.The NAFZ represents a 1600-km-long plate boundary that slips at an average rate of 20–30 mm·yr-1 (McClusky et al., 2000. It has developed in the framework of the northward moving Arabian plate and the Hellenic subduction zone where the African lithosphere is subducting below the Aegean. Comparison of long-term slip rates with Holocene and GPS-derived slip rates indicate an increasing westwardmovement of the Anatolian plate with respect to stable Eurasia. During the twentieth century, the NAFZ has ruptured over 900 km of its length. A series of large earthquakes starting in 1939 near Erzincan in Eastern Anatolia propagated westward towards the Istanbul-Marmara region in northwestern Turkey that today represents a seismic gap along a ≥100-km-long segment below the Sea of Marmara. This segment did not rupture since 1766 and, if locked, may have accumulated a slip deficit of 4–5 m. It is believed being capable of generating two M≥7.4 earthquakes within the next decades (Hubert-Ferrari et al., 2000; however, it could even rupture in a large single event (Le Pichon et al., 1999.

  15. Heart failure in North America.

    Blair, John E A; Huffman, Mark; Shah, Sanjiv J

    2013-05-01

    Heart failure is a major health problem that affects patients and healthcare systems worldwide. Within the continent of North America, differences in economic development, genetic susceptibility, cultural practices, and trends in risk factors and treatment all contribute to both inter-continental and within-continent differences in heart failure. The United States and Canada represent industrialized countries with similar culture, geography, and advanced economies and infrastructure. During the epidemiologic transition from rural to industrial in countries such as the United States and Canada, nutritional deficiencies and infectious diseases made way for degenerative diseases such as cardiovascular diseases, cancer, overweight/obesity, and diabetes. This in turn has resulted in an increase in heart failure incidence in these countries, especially as overall life expectancy increases. Mexico, on the other hand, has a less developed economy and infrastructure, and has a wide distribution in the level of urbanization as it becomes more industrialized. Mexico is under a period of epidemiologic transition and the etiology and incidence of heart failure is rapidly changing. Ethnic differences within the populations of the United States and Canada highlight the changing demographics of each country as well as potential disparities in heart failure care. Heart failure with preserved ejection fraction makes up approximately half of all hospital admissions throughout North America; however, important differences in demographics and etiology exist between countries. Similarly, acute heart failure etiology, severity, and management differ between countries in North America. The overall economic burden of heart failure continues to be large and growing worldwide, with each country managing this burden differently. Understanding the inter-and within-continental differences may help improve understanding of the heart failure epidemic, and may aid healthcare systems in delivering

    Bismarck State College, along with its partners (Williston State College, Minot State University and Dickinson State University), received funding to help address the labor and social impacts of rapid oilfield development in the Williston Basin of western North Dakota. Funding was used to develop and support both credit and non-credit workforce training as well as four major symposia designed to inform and educate the public; enhance communication and sense of partnership among citizens, local community leaders and industry; and identify and plan to ameliorate negative impacts of oil field development.

  18. North American Natural Gas Markets

    This report sunnnarizes the research by an Energy Modeling Forum working group on the evolution of the North American natural gas markets between now and 2010. The group's findings are based partly on the results of a set of economic models of the natural gas industry that were run for four scenarios representing significantly different conditions: two oil price scenarios (upper and lower), a smaller total US resource base (low US resource case), and increased potential gas demand for electric generation (high US demand case). Several issues, such as the direction of regulatory policy and the size of the gas resource base, were analyzed separately without the use of models

  20. Spotted hyena from north China

    2009-01-01

    @@ Acomplete fossil skeleton of spotted hyena unearthed on 26 July, 2008 in nearly perfect preservation, exhilarates CAS paleontologists, as the discovery in north China might offer new clues about the interactions between prehistoric faunas of Africa and Eurasia, and meanwhile afford a clue to the big extinction of large amount of species occurring about 11,000 years ago. Hinting at possible connections between species from Africa and Eurasia, the discovery would even provide new insights into the "out-of-Africa" model of human origins.

  1. The carbon budget of the North Sea

    A. Vieira Borges

    2004-08-01

    Full Text Available A carbon budget has been established for the North Sea, a shelf sea of the NW European continental shelf. The air-sea exchange of CO2 has been assessed as closing term of the budget. The carbon exchange fluxes with the North Atlantic Ocean dominate the gross carbon budget. The net carbon budget – more relevant to the issue of the contribution of the coastal ocean to the marine carbon cycle – is dominated by the carbon inputs from rivers, the Baltic Sea and the atmosphere. The dominant carbon sink is the final export to the North Atlantic Ocean. The North Sea acts as a sink for organic carbon. More than 90% of the CO2 taken up from the atmosphere is exported to the North Atlantic Ocean making the North Sea a highly efficient continental shelf pump for carbon.

  2. Radioactivity in north european waters

    The primary objective of Working Group 2 of Project MARINA was to consider recent measurements of environmental radioactivity in north European waters and to use this, and other information, to report the likely magnitude of doses to the critical group from marine pathways. The monitoring data were supplemented where appropriate with predictions from simple models. The major sources of radioactivity studied were as follows: liquid wastes from nuclear fuel reprocessing plants; liquid wastes from nuclear power plants and other major nuclear industry sites; solid waste disposal in the deep north-east Atlantic; fallout from Chernobyl; and naturally-occurring radionuclides. Some of the largest doses from marine pathways are predicted for naturally-occurring radionuclides. The highest doses from the nuclear industry were due to the operation of the reprocessing plant at Sellafield. Discharges from this site have been decreasing substantially in recent years and, as a consequence, doses have also been reducing. Predictions of individual doses due to liquid effluents from power stations, solid waste disposal and fallout from Chernobyl are all low

  3. North Africa oil and gas

    During the last decade, Algeria, Egypt and Libya have improved their fiscal terms for oil and gas development to attract more investment in this area. As a group, the three countries are implementing plans to increase crude oil production capacity 16 % from 3.15 million barrels per day (Mb/d) in 1995 to 3.65 Mb/d in the year 2000. Natural gas liquid are also being developed and their production capacity is planned to increase 30 % to 0.82 Mb/d in 2000. Concurrently, natural gas production capacity is being expanded about 50 % by 200 and natural gas exporting capacity should see a 92 % increase in 2000 over 1995 levels in short, the North Africa hydrocarbon producers are rapidly expanding their production and export capacity of gaseous and liquid hydrocarbons. This is the first IEA study to focus on North Africa. It shows how changing hydrocarbon legislation or production sharing agreements can result in changes in crude oil and natural gas production capacity. Much of the expansion outlined in this study is being guided by international oil companies attracted by the improved fiscal terms

  5. North RTL ''grid scan'' studies

    This study was made in response to screen measurements which indicated an emittance growth of nearly a factor of two within the North RTL or linac girder-1. Betatron oscillations are induced at the beginning of the North RTL to search for gross geometric aberrations arising within the RTL or sector-2 of the linac. The oscillations are induced horizontally and vertically with two X or two Y dipole correctors stepped in a nested loop fashion. In both cases the full set of RTL and first girder sector-2 linac beam position monitors (BPMs) are sampled in X and Y for each corrector setting. Horizontal (or vertical) data from pairs of BPMs are then transformed to phase space coordinates by the linear transformation constructed assuming the transport optics between the BPMs is known. A second transformation is then made to normalized phase space coordinates by using Twiss parameters consistent with the assumed transport optics. By careful choice of initial Twiss parameters the initial grid can be made square for convenience in graphical interpretation. A linear ''grid'' is then fitted to the transformed data points for each pair of BPMs. The area of each grid is calculated and linearity qualitatively evaluated. Furthermore, although not the focus of this study, the beta match at each BPM can be quantified. 6 figs

    2009-01-01

    North Korea’s nuclear test serves several purposes. Its first purpose is to bolster the flagging legitimacy of the regime and, by drumming up war hysteria, achieve domestic mobilization in the face of mounting internal difficulties. Throughout North Korea’s turbulent history, the regime has periodically resorted to war hysteria, at times on even grander scale than what we have recently seen. North Korea’s Songun (army-first) policy requires periodic crises to maintain the myth of ...

    1965-09-01

    General conditions of various oil fields in North Sumatra are illustrated. Geologic structure of North Sumatra and that of Rantau Oil Field, the largest among 11 oil fields, is described in detail. Rantau Oil Field has produced more than 14 million kl of crude oil since 1929. It is still going strong and gradually expanding its border to the north. Since 1957, PERMINA (Pertambangan Minjak National) had been the only company with mining right to the oil field, but NSODECO (North Sumatra Oil Development Corporation) joined in development of the oil field since June, 1960. The latter part of this article gives comparison of conditions before and after the participation of NSODECO.

  12. Primary hyperparathyroidism in North India

    Primary hyperparathyroidism (PHPT) has a variable clinical expression. Symptomatic PHPT is still predominant form of the disease in many parts of the world, especially developing countries. Because the clinical profile of the disease has changed from that described in the past we sought to improve our understanding of the disease in patients in North India. We summarized the clinical presentation, biochemical and radiological features, and operative findings from the case records from the last 13 years of 52 patients at a tertiary care center in North India who had documented PHPT. The male: female was 1:3.3 with ages ranging from 6 to 60 years (mean+-SD, 36.38+-12.73). Bone disease (46%), recurrent renal stones (21%) and body aches and pains (21%) were the most common modes of the presentation. The lag time varied ranged from 1 month to 16 years. Common clinical manifestations included bone pain (67%), weakness/fatigue (56%), fracture of long bones (48%), abdominal pain (39%), polyuria (37%) and psychiatric manifestations (23.1%). Hypertension was observed in 42% and a palpable nodule in the neck in 19%. Biochemical features included hypercalcemia (86.5%), hypophosphatemia (65.4%) and hyperphosphatasia (67.3%). Mean intact PTH (+-SD)was 809.0+-696.3 ng/L with levels significantly lower in patients who had only kidney stone diseases compared with those with bone disease (P=0.017). A single parathyroid was localized in 50(98%) patients. Hungry bone disease was seen in 59% patients. (author)

  13. The North Sea Bird Club

    This paper reports that the creation of a club for the purpose of encouraging oil and gas workers to watch birds may not at first seem a viable proposition. To the layperson, birds offshore conjures up an image of hundreds of seagulls following fishing boats, and very little else. Also, the act of birdwatching is not seen as a typical offshore worker's activity. Anyone who has worked on an installation offshore and who has any interest in wildlife will be aware of the occasional presence of land-birds. Two decades ago, prompted by some keen offshore workers, a single oil company set up a monitoring program, which quickly became popular with a number of its employees. Birds seem offshore were recorded on data forms and collected together. At this stage the club was purely another recreation facility; however, when the data were collated it was soon realized that installations offshore were being used as staging posts by birds on migration, and that the information being collected would be of great interest in the study of bird movements. All over Britain, at strategic points on the coastline, there are bird observatories which record the arrival and departure of migrating birds. The presence of several hundred solid structures up and down the North Sea, which are used by birds en route, represents a huge, unique bird observatory, capable of uncovering facts about bird migration which have long eluded land-based scientists. Eleven years ago, the North Sea Bird Club began, composed of eight member companies, a recorder from Aberdeen University and a representative from the Nature Conservancy Council. The club received data from 41 installations, and the recorder collated these on Aberdeen University's computer and produced an annual report of sightings

  14. North Dakota Refining Capacity Study

    2011-01-05

    According to a 2008 report issued by the United States Geological Survey, North Dakota and Montana have an estimated 3.0 to 4.3 billion barrels of undiscovered, technically recoverable oil in an area known as the Bakken Formation. With the size and remoteness of the discovery, the question became 'can a business case be made for increasing refining capacity in North Dakota?' And, if so what is the impact to existing players in the region. To answer the question, a study committee comprised of leaders in the region's petroleum industry were brought together to define the scope of the study, hire a consulting firm and oversee the study. The study committee met frequently to provide input on the findings and modify the course of the study, as needed. The study concluded that the Petroleum Area Defense District II (PADD II) has an oversupply of gasoline. With that in mind, a niche market, naphtha, was identified. Naphtha is used as a diluent used for pipelining the bitumen (heavy crude) from Canada to crude markets. The study predicted there will continue to be an increase in the demand for naphtha through 2030. The study estimated the optimal configuration for the refinery at 34,000 barrels per day (BPD) producing 15,000 BPD of naphtha and a 52 percent refinery charge for jet and diesel yield. The financial modeling assumed the sponsor of a refinery would invest its own capital to pay for construction costs. With this assumption, the internal rate of return is 9.2 percent which is not sufficient to attract traditional investment given the risk factor of the project. With that in mind, those interested in pursuing this niche market will need to identify incentives to improve the rate of return.

  5. The North Pole Environmental Observatory

    Morison, J.; Aagaard, K.; Falkner, K.; Heiberg, A.; McPhee, M.; Moritz, D.; Overland, J.; Perovich, D.; Richter-Menge, J.; Shimada, K.; Steele, M.; Takizawa, T.; Woodgate, R.

    2001-12-01

    The Arctic environment is changing. The North Pole Environmental Observatory (NPEO) was established as a type of program of long-term observations required to understand Arctic change. The North Pole region was chosen because it is central to observed changes, there is a reasonable past history of measurements, and there is often a large gap there in the coverage of surface measurements. NPEO has three main components, (1) an automated drifting station composed of several buoys to measure atmospheric, upper ocean, and ice variables, (2) a sub-surface mooring at the Pole measuring ocean properties and ice draft, and (3) an airborne hydrographic survey that provides a snapshot spatial description of upper ocean properties. The first observatory was established at the Pole in April 2000 by aircraft flying out of Alert. The drifting station portion consisted of ocean ice and meteorological buoys. Over one year the drifting station passed south through Fram Strait and stopped operating in the Greenland Sea. The airborne hydrographic survey made 6 stations between Alert, the Pole, and beyond. The sub-surface mooring was not deployed. In 2001 the drifting station was similar, but the operation was expanded to deploy a 4000-m mooring at the Pole. The mooring includes current meters, C-T sensors, ADCP, and an ice draft-profiling sonar. It will be recovered in 2002. The hydrographic survey covered a new line from the Pole to 85N, 170W. The 2000 hydrographic survey showed that the changes characterizing the Pole region in the 1990s persist, but with some deepening and some slight retreat toward climatology. The section from Alert shows that upper ocean conditions near the coast have become much like the Western Arctic with low mixed layer salinity and a secondary shallow temperature maximum. The observations indicate a general counterclockwise shift in water mass locations. Among other things, the NPEO 2000 drifting station data indicate the cold halocline is still thinner

  6. The North Cotentin radioecology group

    On January 11., 97, the epidemiologist Jean-Francois Viel publishes a study on the risks of leukaemia of the children in the canton of Beaumont-Hague (Manche), situated near the site of the reprocessing plant of spent fuel of Cogema. Advancing the hypothesis of a link between the exposure to radioactive waste and the appearance of case of the disease in the region, the study creates at once the scandal within the scientific community and within the general public. Worrying about the affair, Ministers in charge of environment and health decide to create a first scientific commission in which participates Jean-Francois Viel. But the tensions are so important within this association that at the end of six months its president decides to resign. It is at this moment there of the story of this debate that the evidence was imperative: it was necessary to innovate by putting around the table experts of any origin to estimate the risks of leukaemia which can result from exposures of the populations of the North Cotentin to ionizing radiations. Placed under Annie Sugier presidency, then manager of the protection in the I.P.S.N. (Institute of protection and nuclear safety), the pluralistic group, called 'North Cotentin radioecology group' ( G.R.N.C.), who collected 50 experts, represents an innovative way of entering in the evaluation and the management of the risks and in the acceptability of the uncertainty. The originality of the G.R.N.C. lies in a critical step as exhaustive as possible which allows to end in the production of shared knowledge. The direction the economic studies and the environmental evaluation of the Ministry of ecology and sustainable development considered important to make the story of the G.R.N.C. better known. To bring to a successful conclusion this project of edition, a work group was set up by the service of Research) and the forward-looking and the drafting of the work was entrusted to a journalist, Yves Miserey and to an ethnologist, Patricia

  7. Voluntary sterilization in North Tyneside.

    Carnegie-Smith, K

    1984-04-01

    Since 1975, sterilization operations, on both men and women have been performed with increasing frequency within the National Health Service in the North Tyneside Area in northeast England. A prospective study was undertaken to discover some of the reasons why healthy young men and women chose surgical sterilization rather than use the established reversible methods of family planning available to them. The study examined some of the characteristics of those requesting sterilization, attempted to understand why they did so at that particular time, and assessed the patient-perceived morbidity resulting from this elective procedure. The study population included all individuals referred for consultation following the patient's request for voluntary sterilization by vasectomy or occlusive tubal surgery, during the period of 1 year (August 1, 1980-July 31, 1981). Women sterilized in association with a pregnancy outcome were not included in the study. Data on pregnancies and sterilizations in North Tyneside demonstrate a rapid increase in requests for vasectomy after 1975. Patients requesting sterilization were admitted to the study during the initial out-patient appointment with their surgeon. Couples seeking sterilization show similar age range for men (mean 34.2) and women (33.1). The proportion of patients who were not married at the time of the operation is perhaps a reflection of doctors' increasing willingness to perform sterilizations on the unmarried, and of individuals to seek such surgery in a committed manner. The increasing tendency for requests to be received from people still in their early 20s is seen as a problem. Data indicates that married people who request the operation at an early age are also those who were married under age 21, started a family immediately and with a 25% divorce rate. At the other end of the age range, couples who ahve been sucessfully using oral contraceptives have become concerned about its safety, especially after age 35. Data

  8. North American tidal power prospects

    Wayne, W. W., Jr.

    1981-07-01

    Prospects for North American tidal power electrical generation are reviewed. Studies by the US Army Corps of Engineers of 90 possible generation schemes in Cobscook Bay, ME, indicated that maximum power generation rather than dependable capacity was the most economic method. Construction cost estimates for 15 MW bulb units in a single effect mode from basin to the sea are provided; five projects were considered ranging from 110-160 MW. Additional tidal power installations are examined for: Half-Moon Cove, ME (12 MW, 18 ft tide); Cook Inlet, AK, which is shown to pose severe environmental and engineering problems due to fish migration, earthquake hazards, and 300 ft deep silt deposits; and the Bay of Fundy, Canada. This last has a 17.8 MW plant under construction in a 29 ft maximum tide area. Other tidal projects of the Maritime Provinces are reviewed, and it is noted that previous economic evaluations based on an oil price of $16/barrel are in need of revision.

    The wide ranging changes that will drive the evolution of the North American electricity industry in the future are discussed. Deregulation and the advent of competition in both the United States and Canada are the principal forces that will change the shape of the electricity market, bringing new players and new forms of doing business into the marketplace. A review of the current state of the business shows that especially in the United States where deregulation began earlier than in Canada, independent generators already constitute a multi-billion dollar industry. Non-utility generation capacity is about seven per cent of total U.S. capacity and accounts for about 10 per cent of total U. S. electricity supply, including imports. Examples from other industries clearly show that restructuring and the breakup of vertically integrated industries could be accomplished much faster than anticipated, that a decrease in prices followed rapidly as products became more like commodities, and that decreasing prices fostered product differentiation and competition. Major legislation affecting the electric power industry in the U.S. and Canada (U.S. National Energy Policy Act 1992, Alberta Electric Utilities Act 1995, Ontario Energy Competition Act 1998) decreeing open access transmission, unbundling of generation, transmission and ancillary services, and promoting competition, and the impacts of these legislative actions are also reviewed. The most visible impact is the explosion that can be seen in power marketing and energy trading on a scale unimaginable only a few short years ago, where the total volume of trade may be worth multiples of the value of the underlying commodity. At the same time, there is concern about the reliability of the system, and thus making it imperative to find new ways to manage reliability. Various suggestions are made as to how increased reliability of supply could be achieved by better management, new standards and better enforcement of

  20. The EPR for North America

    As the supplier of 30 percent of the world's nuclear generating capacity, Framatome ANP, an AREVA and, Siemens company, has been a major contributor in the development of today's international fleet of nuclear power plants. Additionally, as a member of the AREVA global family of companies, Framatome ANP is a major element of the world's largest vertically integrated nuclear supplier. The EPR is the latest evolutionary pressurized water reactor design developed by Framatome ANP. The EPR benefits from the global operating experience of the international fleet of nuclear reactors. Framatome ANP is continuing to play a leadership role in the global renaissance of nuclear power. In December 2003, a Framatome ANP and Siemens consortium signed a firm price, turn-key contract with the Finnish utility TVO for an EPR to be constructed at the Olkiluoto site, In October 2004, it was announced that France would build its first EPR at the Flamanville site as a demonstration plant for a future series of advanced nuclear plants. In February 2005, Framatome ANP submitted a proposal for the supply of four EPR's in China which would be the beginning of a series of new construction in that country. Momentum is also building for new nuclear plants in Canada. Many reports in the past year, including those published by the Canadian Energy Research Institute, indicate that new electricity supplies will be required to meet the growing energy needs of Canada, especially in Ontario. The shutdown of approximately 7,000 MWe of coal-fired generation in Ontario by 2007 will further complicate the energy supply situation. Furthermore, various reports indicate as much as 24,000 MWe of new Canadian electricity generation could be required by 2020. Due to this developing potentially large electricity supply-demand imbalance, some industry officials believe the first North American order for a new nuclear plant will be placed in Canada. It is not surprising then that Framatome ANP is focusing on

  4. Martian north polar cap summer water cycle

    Brown, Adrian J; Becerra, Patricio; Byrne, Shane

    2016-01-01

    A key outstanding question in Martian science is 'are the polar caps gaining or losing mass and what are the implications for past, current and future climate?' To address this question, we use observations from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) of the north polar cap during late summer for multiple Martian years, to monitor the summertime water cycle in order to place quantitative limits on the amount of water ice deposited and sublimed in late summer. We establish here for the first time the summer cycle of water ice absorption band signatures on the north polar cap. We show that in a key region in the interior of the north polar cap, the absorption band depths grow until Ls=120, when they begin to shrink, until they are obscured at the end of summer by the north polar hood. This behavior is transferable over the entire north polar cap, where in late summer regions 'flip' from being net sublimating into net condensation mode. This transition or 'mode flip' happens earlier for ...

  5. Nitrous oxide in the North Atlantic Ocean

    S. Walter

    2006-01-01

    Full Text Available In order to get a comprehensive picture of the distribution of nitrous oxide (N2O in the North Atlantic Ocean, measurements of dissolved nitrous oxide were made during three cruises in the tropical, subtropical and cold-temperate North Atlantic Ocean in October/November 2002, March/April 2004, and May 2002, respectively. To account for the history of atmospheric N2O, we suggest a new depth-dependent calculation of excess N2O (ΔN2O. N2O depth profiles showed supersaturation throughout the water column with a distinct increasing trend from the cold-temperate to the tropical region. Lowest nitrous oxide concentrations, near equilibrium and with an average of 11.0±1.7 nmol L−1, were found in the cold-temperate North Atlantic where the profiles showed no clear maxima. Highest values up to 37.3 nmol L−1 occurred in the tropical North Atlantic with clear maxima at approximately 400 m. A positive correlation of nitrous oxide with nitrate, as well as excess nitrous oxide with the apparent oxygen utilization (AOU, was only observed in the subtropical and tropical regions. Therefore, we conclude that the formation of nitrous oxide via nitrification occurs in the tropical region rather than in the cold-temperate region of the North Atlantic Ocean

  6. Petroleum geology of offshore North Sumatra

    Sekiya, E.; Inomata, T.

    1967-07-01

    Oil exploration in the Strait of Malacca, North Sumatra, is controlled by P.N. Permina (Persuhaan Negara Pertambangan Minjak Masional) oil company, owned by the government of Indonesia. In 1963, the company granted some rights for developing that area to REFICAN (Refining Associates of Canada). In 1966, the exploration activites were transferred to NOSOPEX (North Sumatra Offshore Petroleum Exploration Co. Ltd.). Up to the present time, the company has continued to explore at that area. The geologic structure of the land and offshore areas was studied. This report reviews the literature on that area in detail. The inland geological structure is based on a report by Mayer and Morgan and the first and second geological report of NOSODECO (North Sumatra Oil Development Co. Ltd.). The offshore geological structure is based on well information supplied by REFICAN. (25 refs.)

    Between June 2004 and September 2004 a temporary seismic network was installed on the northern insular shelf of Iceland and onshore in north Iceland. The seismic setup aimed at resolving the subsurface structure and, thus, the geodynamical transition from Icelandic crust to typical oceanic crust along Kolbeinsey Ridge. The experiment recorded about 1,000 earthquakes. The region encloses the Tjörnes Fracture Zone containing the Husavik-Flatey strike-slip fault and the extensional seismic Grimsey Lineament. Most of the seismicity occurs in swarms offshore. Preliminary results reveal typical mid-ocean crust north of Grimsey and a heterogeneous structure with major velocity anomalies along the seismic lineaments and north-south trending subsurface features. Complementary bathymetric mapping highlight numerous extrusion features along the Grimsey Lineament and Kolbeinsey Ridge. The seismic dataset promises to deliver new insights into the tectonic framework for earthquakes in an extensional transform zone along the global mid-ocean ridge system.

    We present two different elastic models for, respectively, cemented and uncemented North Sea chalk well-log data. We find that low Biot coefficients correlate with anomalously low cementation factors from resistivity measurements at low porosity and we interpret this as an indication of cementation......-saturated North Sea reservoir chalk. In the acoustic impedance–Poisson's ratio plane, we forecast variations in porosity and hydrocarbon saturation from their influence on the elastic behaviour of the chalk. The Gassmann model and the self-consistent approximation give roughly similar predictions of the effect of...... filtrate. The amplitude-versus-angle (AVA) response for the general North Sea sequence of shale overlying chalk is predicted as a function of porosity and pore-fill.

    The Marine Geology Unit of the Department of Earth Sciences organized the second Marine Geology symposium at Aarhus University, 7-8 October 1993. The intention was to bring together people working especially with the geology of the North Sea and Skagerrak. Approximately 60 people from different Danish and Norwegian institutions attended the symposium. 28 oral presentations were given and 2 posters presented. A large range of geological topics was covered, embracing biostratigraphy, sequence stratigraphy, sedimentology and structural geology. The majority of the presentations dealt with Quaternary geology and Cenozoic sequence stratigraphy, but also Jurassic and Lower Cretaceous stratigraphy was treated. Studies from the major part of the Danish sector were presented, spanning from Bornholm to the central North Sea, and further into the Norwegian North Sea sector. (au)

  14. Ammonia downstream from HH 80 North

    Girart, Jose M.; Rodriguez, Luis F.; Anglada, Guillem; Estalella, Robert; Torrelles, Jose, M.; Marti, Josep; Pena, Miriam; Ayala, Sandra; Curiel, Salvador; Noriega-Crespo, Alberto

    1994-01-01

    HH 80-81 are two optically visible Herbig-Haro (HH) objects located about 5 minutes south of their exciting source IRAS 18162-2048. Displaced symmetrically to the north of this luminous IRAS source, a possible HH counterpart was recently detected as a radio continuum source with the very large array (VLA). This radio source, HH 80 North, has been proposed to be a member of the Herbig-Haro class since its centimeter flux density, angular size, spectral index, and morphology are all similar to those of HH 80. However, no object has been detected at optical wavelengths at the position of HH 80 North, possibly because of high extinction, and the confirmation of the radio continuum source as an HH object has not been possible. In the prototypical Herbig-Haro objects HH 1 and 2, ammonia emission has been detected downstream of the flow in both objects. This detection has been intepreted as a result of an enhancement in the ammonia emission produced by the radiation field of the shock associated with the HH object. In this Letter we report the detection of the (1,1) and (2,2) inversion transitions of ammonia downstream HH 80 North. This detection gives strong suppport to the interpretation of HH 80 North as a heavily obscured HH object. In addition, we suggest that ammonia emission may be a tracer of embedded Herbig-Haro objects in other regions of star formation. A 60 micrometer IRAS source could be associated with HH 80 North and with the ammonia condensation. A tentative explanation for the far-infrared emission as arising in dust heated by their optical and UV radiation of the HH object is presented.

    Described is tender-assisted drilling (TAD) on the UK North Sea Gannet field. The Gannet field is developed by Shell UK Exploration and Production (Shell Expro). In March 1990, Shell Expro awarded Sedco Forex the design and engineering contract to convert the semisubmersible drilling rig Sedco 704 into the Gannet TSV (Tender Support Vessel). The only semisubmersible TSV operation so far to have completed drilling in the North Sea has been in the Norwegian sector. The Odin field, operated by Esso Norge a/s, was developed using the converted drilling rig Treasure Hunter. 1 fig., 1 ill., 3 refs.

  16. Energy geopolitics moves toward the Great North

    Because of the developing political chaos in the Middle-East and of the political problems of Russia (Tchetchenia, North-Ossetia, and more recently in its relations with Ukraine), the geopolitics of petroleum is moving towards the North: Baltic, Barents and Bering seas. This trend will concern in particular the Siberian gas, the Norwegian gas and the petroleum from Alaska. The conclusion of the author is that this northward move is favourable to the interests of the United States which will remain the 'masters of the energy geopolitical game'. (J.S.)

  17. Tropical North Africa hydro climate variability

    NCEP/NCAR data are used to study the modulating circulations of the hydro climate of tropical North Africa. Wavelet analysis is used to identify modes of variability of stream flows within the region. Ocean-atmosphere circulation composites are considered to unravel the mechanisms for swing of stream flows. The one of the main finding of the study reveals that hydro climate variability swings within ENSO and decadal timescale. Pacific and Atlantic sea surface temperatures control the hydro climate mode of variability. Associated to Pacific sea surface temperature, the Atlantic Walker Circulation modulates the hydro climate swing of tropical North Africa. The detail result will be discussed.(Author)

    1989-01-01

    A major series of CZCS satellite images of the North Sea has been processed to obtain information on the distribution of optical properties of chlorophyll, suspended sediments and coccolithophore blooms. The atmospheric correction of the scenes has been carried out after the method suggested by Gordon et al. (1983) and also by the interactive aerosol removal technique suggested by Arnone and LaViolette (1984). The processing techniques are described in relation to problems encountered in a case II water area such as the North Sea. Examples of atmospherically corrected CZCS images are presented and compared with available in situ chlorophyll.

  1. North Pacific sea ice cover, a predictor for the Western North Pacific typhoon frequency?

    2007-01-01

    The relationship between the sea ice cover in the North Pacific and the typhoon frequency has been studied in this paper. It follows that the index for the sea ice cover in the North Pacific (ISA) both in December-January-February (DJF) and in March-April-May (MAM) is negatively correlated with annual typhoon number over the western North Pacific (TNWNP) during 1965―2004, with correlation coeffi-cients of -0.42 and -0.49 respectively (above 99% significant level). Large sea ice cover in the North Pacific tends to decrease TNWNP. Positive ISA (MAM) is associated with the tropical circulation and SST anomalies in the North Pacific, which may lead to unfavorable dynamic and thermal conditions for typhoon genesis over WNP from June to October (JJASO). The variability of the atmospheric circula-tion over the North Pacific, associated with the ISA anomaly in MAM is connected to the tropical at-mospheric circulation variability in MAM via the teleconnection wave train. Besides, as the tropical circulation has strong seasonal persistency from the MAM to JJASO, thus, the ISA in MAM-related variability of the tropical atmospheric circulation as well as the SST can affect the typhoon activity over the western North Pacific.

    The cause of decadal climate variability over the North Pacific and North America is investigated by analyzing data from a multi-decadal integration with a state of the art coupled ocean-atmosphere model and observations. About one third of the low-frequency climate variability in the region of interest can be attributed to a cycle involving unstable air-sea interactions between the subtropical gyre circulation in the North Pacific and the Aleutian low pressure system. The existence of this cycle provides a basis for long-range climate forecasting over the western United States at decadal time scales. (orig.)

  4. The mystery of the "North of the North" in Ibsen's works

    Jon Nygaard

    2015-01-01

    It is an exaggeration to claim that several of the protagonists in Ibsen’s dramatic works are from the north, or have lived there. The few characters in Ibsen’s drama related to the North are, however, given a special emphasis in his works. They are, like the landscape and the light of the North, mysterious, strange, strong and untamed. Or they have been exiled, suppressed or forgotten – and then suddenly arrive unexpectedly and challenge the established order and open new tension and ambitio...

  8. North Korea -- Still an Intelligence Problem

    Stephan Blancke

    2014-06-01

    Full Text Available A few years after Kim Jong Un came into office, North Korea is still attracting controversy in the headlines, and political sanctions are still in operation. Despite the harsh measures in place to isolate Pyongyang from sources of money and luxury, the rulers are able to get what they want using front companies or the help of other states. The reasons for this are deeply rooted in the North Korean political structure. A network of high ranking officials, their children, and political minions are grappling for power and wealth. Beside the powerful Kim clan there exist other families in North Korea whose loyalty must be secured with bribes. If the loyalty of the influential families is eroded, the power base of Kim Jong Un is likely to soon diminish. As a result, the North Korean government is searching for sources of money. Illicit drugs may be one solution the ruling regime find attractive to this problem, but there appears to be a twist: struggling ordinary citizens are showing signs that they too are taking part in this illegal enterprise. This is manifested by their willingness to become involved in crime in the same way as the corrupt regime.

    Accelerated biodiversity assessment is the key to understanding the relationship between biodiversity and ecosystem functioning, especially in times of rapid climate change and habitat destruction. For the marine fauna of the North Sea, morphological species identification is impaired by the small size of many taxa, morphological convergence, intraspecific variation and larval stages which often elude morphological identification. Accordingly, the use of molecular methods...

  18. Chinese Studies Librarianship in North America

    Karen T. Wei

    2004-01-01

    Although American libraries had begun collecting Chinese language materials in the 19th century, notably the United States Library of Congress in 1869, Yale in 1878, Harvard in 1879, and Berkeley in 1896, East Asian studies librarianship in North America, including China studies librarianship, was not fully developed until the 1960s. There was no formal organization that represented the interest of Chinese studies librarians because there were few of them and most of them were China scholars rather than trained librarians. More than 100 years later, the number of Chinese studies librarians in North America has increased considerably,primarily in response to the demand in the field of China studies and more recently to the needs of immigrant population and the general public who has an interest in China.This paper traces the history and growth of Chinese studies librarianship in North America, documents the development of the professional organization that represents Chinese studies librarians, and examines the training programs that prepare them for their jobs. It also attempts to propose an international exchange forum aiming to bring together Chinese studies librarians in North America and librarians in China in sharing their experience and expertise to achieve the ultimate goal of serving the users.

  19. Opportunities for suppliers in the North Sea

    If European suppliers to the offshore industry are to prosper, it has to be on the basis of a single internationally competitive North Sea market. If we continue to talk and think in terms of a British sector, a Norwegian sector, Dutch and Danish sectors, then we will inhibit the full development of contractors and suppliers. The long term future in oilfield supplies lies in a mixed portfolio of international projects. Oil and gas exploration and development, particularly offshore, is notoriously cyclical. To survive the downturns in one market supply, companies need to have access to the upswing in others. The significance of a single North Sea market is that it presents an international arena for the best companies to demonstrate their technical and commercial abilities. Individual national sectors do not - cannot - provide that opportunity to anything like the same extent. Taking then the North Sea as a single competitive market, it represents the most important offshore area in the world at the present time, and this is likely to continue during the 1990s. The prospects of achieving a single North Sea market are discussed. (author)

  1. Forest health conditions in North America

    Some of the greatest forest health impacts in North America are caused by invasive forest insects and pathogens (e.g., emerald ash borer and sudden oak death in the US), by severe outbreaks of native pests (e.g., mountain pine beetle in Canada), and fires exacerbated by changing climate. Ozone and N and S pollutants continue to impact the health of forests in several regions of North America. Long-term monitoring of forest health indicators has facilitated the assessment of forest health and sustainability in North America. By linking a nationwide network of forest health plots with the more extensive forest inventory, forest health experts in the US have evaluated current trends for major forest health indicators and developed assessments of future risks. Canada and Mexico currently lack nationwide networks of forest health plots. Development and expansion of these networks is critical to effective assessment of future forest health impacts. - The forests of North America continue to face many biotic and abiotic stressors including fragmentation, fires, native and invasive pests, and air pollution

  3. Solar cycle modulation of the Pacific–North American teleconnection influence on North American winter climate

    We investigate the role of the 11-year solar cycle in modulating the Pacific–North American (PNA) influence on North American winter climate. The PNA appears to play an important conduit between solar forcing and surface climate. The low solar (LS) activity may induce an atmospheric circulation pattern that resembles the positive phase of the PNA, resulting in a significant warming over northwestern North America and significant dry conditions in the Pacific Northwest, Canadian Prairies and the Ohio-Tennessee-lower Mississippi River Valley. The solar-induced changes in surface climate share more than 67% and 14% of spatial variances in the PNA-induced temperature and precipitation changes for 1950–2010 and 1901–2010 periods, respectively. These distinct solar signatures in North American climate may contribute to deconvolving modern and past continental-scale climate changes and improve our ability to interpret paleoclimate records in the region.

  15. North by north-west: climate change and directions of density shifts in birds.

    Lehikoinen, Aleksi; Virkkala, Raimo

    2016-03-01

    There is increasing evidence that climate change shifts species distributions towards poles and mountain tops. However, most studies are based on presence-absence data, and either abundance or the observation effort has rarely been measured. In addition, hardly any studies have investigated the direction of shifts and factors affecting them. Here, we show using count data on a 1000 km south-north gradient in Finland, that between 1970-1989 and 2000-2012, 128 bird species shifted their densities, on average, 37 km towards the north north-east. The species-specific directions of the shifts in density were significantly explained by migration behaviour and habitat type. Although the temperatures have also moved on average towards the north north-east (186 km), the species-specific directions of the shifts in density and temperature did not correlate due to high variation in density shifts. Findings highlight that climate change is unlikely the only driver of the direction of species density shifts, but species-specific characteristics and human land-use practices are also influencing the direction. Furthermore, the alarming results show that former climatic conditions in the north-west corner of Finland have already moved out of the country. This highlights the need for an international approach in research and conservation actions to mitigate the impacts of climate change. PMID:26691578

  16. Is There Really A North American Plate?

    Krill, A.

    2011-12-01

    Lithospheric plates are typically identified from earthquake epicenters and evidence such as GPS movements. But no evidence indicates a plate boundary between the North American and South American Plates. Some plate maps show them separated by a transform boundary, but it is only a fracture zone. Other maps show an "undefined plate boundary" or put no boundary between these two plates (check Google images). Early plate maps showed a single large American Plate, quite narrow east of the Caribbean Plate (Le Pichon 1968, Morgan 1968). The North and South American Plates became established by the leading textbook Earth (Press & Siever 1974). On their map, from a Scientific American article by John Dewey (1972), these new plates were separated by an "uncertain plate boundary." The reasons for postulating a North American Plate were probably more psychological than geological. Each of the other continents of the world had its own plate, and North American geologists naturally wanted theirs. Similarly, European geographers used to view Europe as its own continent. A single large plate should again be hypothesized. But the term American Plate would now be ambiguous ("Which plate, North or South?") Perhaps future textbook authors could call it the "Two-American Plate." Textbook authors ultimately decide such global-tectonic matters. I became aware of textbook authors' opinions and influence from my research into the history of Alfred Wegener's continental drift (see Fixists vs. Mobilists by Krill 2011). Leading textbook author Charles Schuchert realized that continental drift would abolish his cherished paleogeographic models of large east-west continents (Eria, Gondwana) and small oceans (Poseiden, Nereis). He and his junior coauthors conspired to keep drift evidence out of their textbooks, from the 1934-editions until the 1969-editions (Physical Geology by Longwell et al. 1969, Historical Geology by Dunbar & Waage 1969). Their textbooks ruled in America. Textbooks

    Donado, Alejandro; Klaus WALDE

    2010-01-01

    We analyse a world consisting of 'the North' and 'the South' where labour standards in the North are set by trade unions. Standards set by unions tend to increase output and welfare. There are no unions in the South and work standards are suboptimal. Trade between these two countries can imply a reduction in work standards in the North. Moreover, when trade unions are established in the South, the North, including northern unions, tends to lose out. Quantitatively, these effects are small and...

  7. Chronic liver disease in Aboriginal North Americans

    John D Scott; Naomi Garland

    2008-01-01

    A structured literature review was performed to detail the frequency and etiology of chronic liver disease (CLD) in Aboriginal North Americans. CLD affects Aboriginal North Americans disproportionately and is now one of the most common causes of death.Alcoholic liver disease is the leading etiology of CLD,but viral hepatitis, particularly hepatitis C, is an important and growing cause of CLD. High rates of autoimmune hepatitis and primary biliary cirrhosis (PBC) are reported in regions of coastal British Columbia and southeastern Alaska. Non-alcoholic liver disease is a common, but understudied, cause of CLD.Future research should monitor the incidence and etiology of CLD and should be geographically inclusive.In addition, more research is needed on the treatment of hepatitis C virus (HCV) infection and non-alcoholicfatty liver disease (NAFLD) in this population.

  8. North America natural gas supply trends

    The paper explores (a) how much natural gas is used in North America, (b) where these supplies of gas come from, and (c) the prognosis for long-term gas supply availability in North America. Natural gas use is growing at 2.6% per year in the US and supplies in the US and Canada are growing 1.4 and 5%, respectively. More basins holding natural gas resources are proving up and developing new reserves using the latest technology and efficiency improvements which ensures longer, more reliable, flexible gas supplies for growing markets throughout the country. As more natural gas and MTBE are used in motor vehicles, (1) pollution problems from motor vehicles will decrease, (2) less oil needs to be imported, (3) more gas production leads to domestic energy jobs being created in the US in more geographic regions, and (4) the domestic economy will benefit

  9. Wildlife response on the Alaska North Slope

    Recognizing the need for a comprehensive plan to deal with potentially oiled wildlife on the Alaskan North Slope, a multifaceted wildlife protection strategy was developed and implemented during 1991. The strategy incorporated all aspects of wildlife response including protection of critical habitat, hazing, capture and stabilization, long term rehabilitation, and release. The primary wildlife response strategy emphasizes controlling of the release and spreading of spilled oil at the source to prevent or reduce contamination of potentially affected species and/or their habitat. A secondary response strategy concentrates on keeping potentially affected wildlife away from an oiled area through the use of deterrent techniques. Tertiary response involves the capture and treatment of oiled wildlife. Implementation of the strategy included the development of specialized training, the procurement of equipment, and the construction of a bird stabilization center. The result of this initiative is a comprehensive wildlife response capability on the Alaskan North Slope. 1 ref., 5 figs., 3 tabs

    Jürgen Sündermann

    2011-09-01

    Full Text Available The current state of understanding the North Sea's physical system is presented. First, basic phenomena like astronomical tides and general circulation will be described and analysed with respect to their physical nature and respective interactions. There will be special focus on fundamental dynamic balances. Next, some specific topics relevant to the marine ecosystem, the economy and society will be considered: among them, spreading and transport processes, the fresh water budget, the heat budget and storm surges. A separate section is dedicated to the North Sea of Tomorrow, i.e. the prospective variations of the physical environment resulting from global changes in future decades. The statements are based on the long experience of the authors and their groups and include findings that are little known if at all. The review finishes with a list of open questions and the corresponding research demands.

  11. Elastic behaviour of North Sea chalk

    2007-01-01

    We present two different elastic models for, respectively, cemented and uncemented North Sea chalk well-log data. We find that low Biot coefficients correlate with anomalously low cementation factors from resistivity measurements at low porosity and we interpret this as an indication of cementation...... self-consistent approximation, which here represents the unrelaxed scenario where the pore spaces of the rock are assumed to be isolated, and the Gassmann theory, which assumes that pore spaces are connected, as tools for predicting the effect of hydrocarbons from the elastic properties of brine......-saturated North Sea reservoir chalk. In the acoustic impedance–Poisson's ratio plane, we forecast variations in porosity and hydrocarbon saturation from their influence on the elastic behaviour of the chalk. The Gassmann model and the self-consistent approximation give roughly similar predictions of the effect of...

  12. In North American energy markets : stronger credibility

    Hydro-Quebec''s competitive position as it expands and diversifies its business in the future was discussed. The utility has an outstanding debt of CAN$37 billion, nevertheless, it is considered to be a solid investment by financial experts. Hydro-Quebec is recognized as North America''s biggest electric utility in terms of sales and also has the lowest cost structure on the continent. Moody Investor Services, Duff and Phelps Credit Rating Co., and Standard and Poor, have recently conducted ratings of the utility''s standing on financial markets. Hydro-Quebec maintained their high ratings, of A2, AA-, and A+ respectively. The restructuring of North American electricity market gives Hydro-Quebec substantial growth potential. The utility has an extensive transmission network and can offer reasonable electricity rates

  14. A tax reprieve for the North Sea?

    The United Kingdom government has for the time being put to one side its intended review of the fiscal regime in the North Sea. Consistently low oil prices over the last year and the consequent effect on production have given rise to this decision. The ongoing debate on oil taxation in the UK over the past 18 months since the advent of a new government is examined. It has its roots in the last major changes to the oil tax regime which were made in 1993. It has been made clear by the government that the taxation review has not been abandoned and could come to the fore again should there be a substantial increase in oil and gas prices or if companies sought premature decommissioning of North Sea fields.

  15. Radioactivity concentrations in the North Sea

    The following nuclides can be detected in the North Sea: 90Sr, 106Ru, 137Cs, 134Cs, 241Am and 244Cm. The water in the channel east of Cherbourg still contains low quantities up to 0.5 pCi/l of the fission product 125Sb (t 1/2=2.77 a). The activity of T is not exactly known, for the german Bay it is estimated to 50 pCi/l. In comparison of these artificial radioactivies with the natural radioactivity of the North Sea, which mainly depends on 40K, 87Rb as well as uranium and decay products, it has to be taken into account that the activity of α- and β-active substances from nuclear weapons tests before 1962 and by controlled discharge from nuclear power plants, amounts to a range of 1%.

  18. North-South Trade and the Environment.

    Copeland, Brian R.; Taylor, M Scott

    1994-01-01

    A simple static model of North-South trade is developed to examine linkages between national income, pollution, and international trade. Two countries produce a continuum of goods, each differing in pollution intensity. The authors show that the higher income country chooses stronger environmental protection and specializes in relatively clean goods. By isolating the scale, composition, and technique effects of international trade on pollution, they show that free trade increases world pollut...

    The aim of the North Cumbria Community Genetics Project is to establish a store of DNA, plasma, and viable cells from a cohort of around 8000 Cumbrian infants. To meet this objective, specimens of umbilical cord blood and tissue will be collected with maternal consent from babies born at the West Cumberland Hospital, Whitehaven over a five year period from January 1996. These samples will be used in a series of genetic and epidemiological studies investigating the interaction between genes, t...

  20. The North Sea reservoir chalk characterization

    Kallesten, Emanuela

    2015-01-01

    A significant amount of the hydrocarbon production in the North Sea is related to chalk reservoirs. Since 1969, the chalk play remains one of the most important oil sources in Norway. With the initial expected recovery factor 17%, development in technologies and methods contributed to a substantial increase in oil recovery to an approximately 40%. Much of the reserves in place are yet to be extracted, and secondary and tertiary recovery methods need to advance in order to mobilize the remaini...

  4. North Sea sensitivity to atmospheric forcing

    Skogen, Morten D.; Drinkwater, Ken; Solfrid S. Hjøllo; Schrum, Corinna

    2011-01-01

    The sensitivity of North Sea physics and phytoplankton production to atmospheric forcing has been studied by performing perturbations of the atmospheric forcing fields through a number of model simulations. The perturbations are kept in the range of expected climate change, to give a first indication of the climate change impacts on regional systems. The model simulations suggest that an increase in air temperature and short wave radiation will increase sea surface temperature, while an incre...

  8. Global warming and north-south solidarity

    The discussion on climate change is based on 'contradictory certainties'. All sides claim to have found the truth. Much has been written and said about the connection between global warming, biodiversity and over population. The impoverished countries of the South se the insatiable intentions of the North as the major threat to the environment; and global warming as an excuse for stopping the economic development of the south

  12. North America and Asia Pacific LNG markets

    The liquefied natural gas (LNG) export opportunities in the Asia Pacific market were reviewed. Some of the differences that affect a North American LNG projects compared to more typical LNG projects were also outlined. The two main aspects of the LNG market in North America include the establishment of LNG import terminals on the east and southern coasts of the United States and the development of export oriented LNG projects. The Pac-Rim LNG project calls for initial delivery to South Korea of 4.0 MTPA by the end of 2000. A large LNG project has also been proposed for the year 2005 which would use Prudhoe Bay gas. Generally, in North America, there is little use for large scale LNG import projects because of the vast pipeline network that delivers gas reliably and at low cost anywhere in North America. However, LNG remains a good alternative for the Asia Pacific region because of the lack of a pipeline network. Also, Japan, Korea and Taiwan, the three main centers for LNG demand, have no domestic energy supplies and rely on imported energy sources. China is another major market opportunity for LNG. The Pac-Rim LNG project differs from others of its kind in that usually, an LNG project is based on the availability of large reservoirs of natural gas owned by state governments and involves production agreements with multi-national oil and gas companies. This scenario is simply not possible in Canada's deregulated environment. In contrast, the existence of upstream facilities, technical expertise, and low capital costs, hence reduced risks and time to develop an LNG project, gives Canada significant advantages. 3 tabs., 3 figs

    2010-01-01

    The penal system has played a central role in the North Korean government's response to the country's profound economic and social changes. As the informal market economy has expanded, so have the scope of economic crimes. Two refugee surveys--one conducted in China, one in South Korea--document that the regime disproportionately targets politically suspect groups, and particularly those involved in market-oriented economic activities. Levels of violence and deprivation do not appear to diffe...

  14. Propane supply picture: North American perspective

    An overview is presented of the North American propane supply and demand situation. Propane has a distribution network in place and a well established market. North America is virtually self-sufficient in propane with a market of over 1,000,000 bbl/d. Approximately 80% of Canada's propane supply is produced at gas plants in western Canada as a byproduct of natural gas production. The expansion in natural gas markets will mean that propane supply will rise further, unlike crude oil. Canada's daily supply of nearly 160,000 bbl is used for heating (30%), transport (12%), petrochemicals (7.8%), and enhanced oil recovery (4.7%), with the remainder being exported. Propane surpluses are expected to grow, between 70,000 and 100,000 bbl/d in the next 5 years. Nearly 30% of North America's demand for propane is in the petrochemical industry, for which various other feedstocks can be substituted. An availability of over 400,000 bbl/d could fuel ca 5 million vehicles. Only natural gas has a comparable infrastructure and this suffers from high utilization pressure and poor energy density. Wholesale propane is now available at under 9 cents/liter, significantly below the projected ethanol price of 18 cents/liter, which excludes grain feedstock or capital cost. 8 refs., 6 figs

  15. Complex molecules in W51 North region

    Rong, Jialei; Zapata, Luis A; Wu, Yuefang; Liu, Tie; Zhang, Chengpeng; Peng, Yaping; Zhang, Li; Liu, Ying

    2015-01-01

    We present Submillimeter Array (SMA) molecular line observations in two 2 GHz-wide bands centered at 217.5 and 227.5 GHz, toward the massive star forming region W51 North. We identified 84 molecular line transitions from 17 species and their isotopologues. The molecular gas distribution of these lines mainly peaks in the continuum position of W51 North, and has a small tail extending to the west, probably associated with W51 d2. In addition to the commonly detected nitrogen and oxygen-bearing species, we detected a large amount of transitions of the Acetone (CH$_3$COCH$_3$) and Methyl Formate (CH$_3$OCHO), which may suggest that these molecules are present in an early evolutionary stage of the massive stars. We also found that W51 North is an ethanol-rich source. There is no obvious difference in the molecular gas distributions between the oxygen-bearing and nitrogen-bearing molecules. Under the assumption of Local Thermodynamic Equilibrium (LTE), with the XCLASS tool, the molecular column densities, and rota...

  16. Categorical representation of North American precipitation projections

    Greene, Arthur M.; Seager, Richard

    2016-04-01

    We explore use of the familiar tercile framework of seasonal forecasting for the characterization of 21st-century precipitation projections over North America. Consistent with direct analyses of modeled precipitation change, in a superensemble of CMIP5 simulations an unambiguous pattern of shifted tercile population statistics develops as the globe warms. Expressed categorically, frequencies for the low (i.e., dry) tercile increase in the southwestern United States and southward into Mexico and decrease across the northern tier of North America, while counts for the high tercile shift in the opposite sense. We show that as the 21st-century proceeds, changes become statistically significant over wide regions in the pointwise sense, and also when considered as projections on model-specific climate change “fingerprints”. Background noise in the superensemble, against which significance is established, comprises both structural model uncertainty and natural climate variability. The robustness of these findings makes a compelling case for long-range planning for a dryer future in the American Southwest and southward, and wetter one to the north and especially northeast, while communication is facilitated by widespread user familiarity with the tercile format.

  17. Bioavailability of lead in North Sea sediments

    Kersten, M.; Kröncke, I.

    1991-12-01

    As part of an interdisciplinary research programme, lead contents were measured in the polychaete Nephtys spp. and in the sea-urchin Echinocardium cordatum as well as in the respective sediment fractions <20 μm taken from the Dogger Bank proper and the eastern coastal North Sea. A lower lead content was generally observed in the organisms taken from the German Bight than in those from the Dogger Bank, especially from its northeastern part. It is possible to divide both areas according to the slope found in the linear regression of lead versus total organic carbon contents in sediments, which is twice as steep for the Dogger Bank as for the eastern North Sea. This criterium points to a difference in sediment quality with regard to toxic metal contamination. The sediment quality of the Dogger Bank seems to be twice as bad compared with that of the eastern North Sea. This is in good agreement with the differences found in lead contamination of the sediment-dwelling polychaetes from both areas. The results indicate that lead is primarily accumulated by food ingestion.

  18. Uranium resources and geology of North America

    Since about the mid seventies, the International Atomic Energy Agency has held meetings on the geology and uranium resources of different geographic regions of the world. As a continuation of this series the Technical Committee Meeting on Uranium Resources and Geology of North America was held between 1-3 September 1987 in Saskatoon, Canada. The meeting took place in the University of Saskatchewan, hosted by the Department of Geological Sciences in cooperation with the Department of Energy, Mines and Resources Canada. Thirty-six technical papers were presented to a group of over 85 participants from seven countries. These papers provided an excellent coverage of uranium occurrences and deposits and their geological framework in Canada and the USA, with analogies from other parts of the world. North America, the region dealt with in this meeting, is of eminent significance for the world's uranium production and the nuclear industry. Total WOCA U-resources according to the classification developed by the IAEA and the Nuclear Energy Agency of OECD are periodically collected by these two organisations for their report on Uranium Resources, Production and Demand. Currently total WOCA known U resources recoverable at costs of less than $130/kg U or $50/lb U3O8) amount to 3.5 million t U, of which about 25% are located in North America, while the remainder is equally divided among Africa, Australia and the rest of WOCA (Asia, Europe, South America).

    2007-01-01

    The distinctive larval stage of eels (leptocephalus) facilitates dispersal through prolonged life in the open ocean. Leptocephali are abundant and diverse off North Carolina, yet data on distributions and biology are lacking. The water column (from surface to 1,293 m) was sampled in or near the Gulf Stream off Cape Hatteras, Cape Lookout, and Cape Fear, North Carolina during summer through fall of 1999-2005, and leptocephali were collected by neuston net, plankton net, Tucker trawl, and dip net. Additional samples were collected nearly monthly from a transect across southern Onslow Bay, North Carolina (from surface to 91 m) from April 2000 to December 2001 by bongo and neuston nets, Methot frame trawl, and Tucker trawl. Overall, 584 tows were completed, and 224 of these yielded larval eels. The 1,295 eel leptocephali collected (combining all methods and areas) represented at least 63 species (nine families). Thirteen species were not known previously from the area. Dominant families for all areas were Congridae (44% of individuals, 11 species), Ophichthidae (30% of individuals, 27 species), and Muraenidae (22% of individuals, ten species). Nine taxa accounted for 70% of the overall leptocephalus catches (in order of decreasing abundance): Paraconger caudilimbatus (Poey), Gymnothorax ocellatus Agassiz complex, Ariosoma balearicum (Delaroche), Ophichthus gomesii (Castelnau), Callechelys muraena Jordan and Evermann, Letharchus aliculatus McCosker, Rhynchoconger flavus (Goode and Bean), Ophichthus cruentifer (Goode and Bean), Rhynchoconger gracilior (Ginsburg). The top three species represented 52% of the total eel larvae collected. Most leptocephali were collected at night (79%) and at depths > 45 m. Eighty percent of the eels collected in discrete depth Tucker trawls at night ranged from mean depths of 59-353 m. A substantial number (38% of discrete depth sample total) of larval eels were also collected at the surface (neuston net) at night. Daytime leptocephalus

  1. The impact of North Atlantic sea surface temperature errors on the simulation of North Atlantic European region climate

    Keeley, Sarah; Sutton, Rowan; Shaffrey, Len

    2012-01-01

    Current state-of-the-art climate models fail to capture accurately the path of the Gulf Stream and North Atlantic Current. This leads to a warm bias near the North American coast, where the modelled Gulf Stream separates from the coast further north, and a cold anomaly to the east of the Grand Banks of Newfoundland, where the North Atlantic Current remains too zonal in this region. Using an atmosphere-only model forced with the sea surface temperature (SST) biases in the North Atlantic, we...

  2. The North Sea field development guide. V.1: Northern North Sea. V.2: Southern North Sea. 6. ed.

    The 1997/8, sixth edition is the first to be divided into two volumes. Volume 1 covers the central and northern North Sea areas; volume 2 contains the southern North Sea as well as the Irish and German sectors. The pages are numbered consecutively over the two volumes, with page numbers greater than 702 contained in the second volume. There are three index sections. Main index. Arranged by national sector (UK, Norway etc.) Within each sector the entries are alphabetical by operator name. This index contains page numbers for the book entries: the other two index sections should be used with the main index to find the exact location of an entry; Index by field. If the reader knows a field name (e.g. Kittiwake) but not the operator or the national sector, this index will reference them; Index by installation. Each installation (''Fulmar SALM'', ''Togi'') is named, giving the operator, field and national sector where it is located. This index is also useful for locating particular kinds of installations, such as subsea completions; The book is intended to provide a factual overview of field development activity in the North Sea (a term loosely used to include the Irish Sea and the Baltic Sea). The aim is therefore to provide some background, specifications and history on every offshore installation in that area. Speculative or evaluative commentary is avoided where possible. No attempt has been made to forecast the form or probability of future developments, except in those few instances where announcements have been made by the oil company itself, and these are, clearly indicated.

  3. Seasonal Climate Associated with Major Shipping Routes in the North Pacific and North Atlantic

    Jau-Ming Chen

    2014-01-01

    Full Text Available The major shipping routes in the North Pacific (NP and North Atlantic (NA are analyzed via ship-reported records compiled by the International Comprehensive Ocean-Atmosphere Data Set (ICOADS. The shipping route seasonal characteristics and associated climatic features are also examined. In the NP, the dominant cross-basin route takes a great-circle path between East Asia and North America along 54°N54°N north of the Aleutian Islands throughout the year. This route penetrates the Aleutian low center where ocean waves and winds are relatively weaker than those in the _ southern section south of 50°N.50°N. Moreover, the _ spherical shape makes a higher-latitude route shorter in navigational distance across the NP than a lower-latitude route. Two additional mid-latitude routes through the 40°40° - 50°N50°N region appear in summer when the Aleutian low vanishes. In the NA, the major shipping routes form an X-shaped pattern in the oceans south of 40°N40°N to connect North America/the Panama Canal and the Mediterranean Sea/the British Isles and Europe. These major shipping routes are far from the influence of the Icelandic low and thus are used throughout the year due to the stability in marine conditions and their general efficiency. A third and more zonal route appears to the north of the X-shaped routes in the 40°40° - 50°N50°N region. Weak influence from the Icelandic low on marine conditions during summer and spring means that more ships take this route in summer and spring than in winter and fall.

  4. NorthAm Fest : fostering a North American continent approach to countering terrorism.

    Gerdes, Dick (North American Institute, Santa Fe, NM); Moore, Judy Hennessey; Whitley, John B.; Turnley, Jessica Glicken (Galisteo Consulting Group, Inc., Albuquerque, NM); Oborotova, Marina (Center for International Studies of El Colegio de Mexico)

    2004-12-01

    On September 14-16, 2004, the Advanced Concepts Group of Sandia National Laboratories in conjunction with the University of Texas at El Paso and the North American Institute hosted a workshop (fest) designed to explore the concept of a North American continental approach to countering terrorism. The fest began with the basic premise that the successful defense of North America against the threat of terrorism will require close collaboration among the North American allies--Canada, Mexico and the U.S.--as well as a powerful set of information collection and analysis tools and deterrence strategies. The NorthAm Fest recast the notion of ''homeland defense'' as a tri-national effort to protect the North American continent against an evolving threat that respects no borders. This is a report of the event summarizing the ideas explored. The fest examined the uniqueness of dealing with terrorism from a tri-national North American viewpoint, the role and possible features of joint security systems, concepts for ideal continental security systems for North America, and the challenges and opportunities for such systems to become reality. The following issues were identified as most important for the advancement of this concept. (1) The three countries share a set of core values--democracy, prosperity and security--which form the basis for joint interactions and allow for the development of a culture of cooperation without affecting the sovereignty of the members. (2) The creation of a continental defensive strategy will require a set of strategic guidelines and that smart secure borders play a pivotal role. (3) Joint security systems will need to operate from a set of complementary but not identical policies and procedures. (4) There is a value in joint task forces for response and shared information systems for the prevention of attacks. (5) The private sector must play a critical role in cross-border interactions. Finally, participants envisioned a

  5. Mesozoic Rifting in the German North Sea

    Lutz, R.; Jähne, F.; Arfai, J.

    2013-12-01

    The Central Graben is the southernmost expressions of the Mesozoic North Sea rift system that includes the Viking Graben, Moray Firth-Witch Ground grabens and the Horda-Egersund half graben. In the southern North Sea the Central Graben extends across the Dutch and the German exclusive economic zones. The structure of the Central Graben in German territorial waters was mapped in great detail in 2D and 3D seismic data and the stratigraphy has been constraint by borehole data. We provide a detailed review of the rifting activity in the German North Sea sector both in time and space and the link between rifting and salt movement. Major rifting activity started in the Central Graben during the Late Triassic and peaked during the Late Jurassic when extensive rift grabens formed, further influenced by halokinetic movements. First subsidence in the Central Graben area appears in the Early Triassic. This is documented by thickness variations in the sedimentary strata from the Triassic to the Jurassic. Remarkably thick sediments were deposited during the Late Triassic along the eastern border fault of the Central Graben and in the Late Jurassic sediments accumulated along graben-wide extensional faults and in rim-synclines of salt-structures. A basin inversion commenced in the Late Cretaceous resulting in an erosion of wide portions of Lower Cretaceous rocks or even complete removal in some parts. The area to the east of the Central Graben faced a completely different evolution. In this area major rifting activity initiated already in the Early to Middle Triassic. This is evident from huge packages of Middle Buntsandstein to Muschelkalk (Middle Triassic) sediments in the Horn Graben. Jurassic doming, forming the Mid-North Sea High, resulted in almost complete erosion of Lower and Middle Jurassic sediments in the central German North Sea. Sedimentation continued during the Early and Late Cretaceous. The Glückstadt Graben, which is a structure located farther east has a

  6. North Atlantic, ITCZ, and Monsoonal Climate Links

    Haug, G. H.; Deplazes, G.; Peterson, L. C.; Brauer, A.; Mingram, J.; Dulski, P.; Sigman, D. M.

    2008-12-01

    Major element chemistry and color data from sediment cores in the anoxic Cariaco Basin off Venezuela record with (sub)annual resolution large and abrupt shifts in the hydrologic cycle of the tropical Atlantic during the last 80 ka. These data suggest a direct connection between the position of the ITCZ over northern South America, the strength of trade winds, and the temperature gradient to the high northern latitudes, ENSO, and monsoonal climate in Asia. The mechanisms behind these decadal-scale ITCZ-monsoon swings can be further explored at major climate transitions such as the onset of Younger Dryas cooling at ~12.7 ka, one of the most abrupt climate changes observed in ice core, lake and marine records in the North Atlantic realm and much of the Northern Hemisphere. Annually laminated sediments from ideally record the dynamics of abrupt climate changes since seasonal deposition immediately responds to climate and varve counts accurately estimate the time of change. We compare sub-annual geochemical data from a lake in Western Germany, which provides one of the best-dated records currently available for this climate transition, with the new the Cariaco Basin record and a new and higher resolution record from Lake Huguang Maar in China, and the Greenland ice core record. The Lake Meerfelder Maar record indicates an abrupt increase in storminess, occurring from one year to the next at 12,678 ka BP, coincident with other observed climate changes in the region. We interpret this shift of the wintertime winds to signify an abrupt change in the North Atlantic westerlies to a stronger and more zonal jet. The observed wind shift provides the atmospheric mechanism for the strong temporal link between North Atlantic overturning and European climate during the last deglaciation, tightly coupled to ITCZ migrations observed in the Cariaco Basin sediments, and a stronger east Asian Monsoon winter monsoon as seen in lake Huguang Maar, when cave stalagmite oxygen isotope data

  7. Integration of the North American energy market

    The US energy policy of President Bush administration proposes to develop a North American energy framework with a greater energy integration between Canada, the USA and Mexico in the respect of the sovereignty of each country. This article tries to evaluate the integration status of the energy sector in Northern America with respect to the North American free-exchange agreement and to the deregulation process observed in the natural gas and electric power sectors. The commercial energy fluxes between Canada, Mexico and the US show that the integration is a reality and that it is in constant progress. This integration is particularly important in the case of Canada and the USA while major constraints remain in Mexico where the property and exploitation of natural resources is a government monopoly. For this reason, Mexico could never exploit the full potentialities of its resources and suffers from a chronical under-investment in its energy infrastructures which limits the energy trade. Despite this, there is a strong will from the Mexican authorities to ensure the modernization of its energy sector and to contribute more to the integration process of the north American energy market. A series of reforms, and in particular the fiscal reform started by the government should reduce the excessive dependence of the government incomes with the dividends from the energy sector. This should allow the different government companies to reinvest more its benefits in order to improve the existing infrastructures and to increase the capacities (in particular in the gas and electricity sectors). Finally, the recent will of the government to open the gas sector should allow the development of this energy source. (J.S.)

  8. NOrth AMerica Soil (NOAM-SOIL) Database

    Miller, D. A.; Waltman, S. W.; Geng, X.; James, D.; Hernandez, L.

    2009-05-01

    NOAM-SOIL is being created by combining the CONUS-SOIL database with pedon data and soil geographic data coverages from Canada and Mexico. Completion of the in-progress NOrth AMerica Soil (NOAM-SOIL) database will provide complete North America coverage comparable to CONUS. Canadian pedons, which number more than 500, have been painstakingly transcribed to a common format, from hardcopy, and key- entered. These data, along with map unit polygons from the 1:1,000,000 Soil Landscapes of Canada, will be used to create the required spatial data coverages. The Mexico data utilizes the INEGI 1:1,000,000 scale soil map that was digitized by U. S. Geological Survey EROS Data Center in the mid 1990's plus about 20,000 pedons. The pedon data were published on the reverse side of the paper 1:250,000 scale Soil Map of Mexico and key entered by USDA and georeferenced by Penn State to develop an attribute database that can be linked to the 1:1,000,000 scale Soil Map of Mexico based on taxonomic information and geographic proximity. The essential properties that will be included in the NOAM-SOIL data base are: layer thickness (depth to bedrock or reported soil depth); available water capacity; sand, silt, clay; rock fragment volume; and bulk density. For quality assurance purposes, Canadian and Mexican soil scientists will provide peer review of the work. The NOAM-SOIL project will provide a standard reference dataset of soil properties for use at 1km resolution by NACP modelers for all of North America. All data resources, including metadata and selected raw data, will be provided through the Penn State web site: Soil Information for Environmental Modeling and Ecosystem Management (www.soilinfo.psu.edu). Progress on database completion is reported.

  9. Echinococcus canadensis transmission in the North.

    Oksanen, Antti; Lavikainen, Antti

    2015-10-30

    The Echinococcus granulosus complex (EG) is the causative agent of cystic echinococcosis (CE). Northern cervid Echinococcus was previously suggested to be the ancestor of the entire EG. During the last century, it was regarded to have three (or four) different, but often overlapping, transmission cycles in the circumpolar North: the original wolf-wild cervid (reindeer or elk)-cycle; the semi-synanthropic cycle involving sled and hunting dogs and wild cervids; and the synanthropic cycle involving herding dogs and semi-domesticated reindeer. Human infections mainly derived from the latter two cycles. In Fennoscandia, the synanthropic cycle has been eliminated during the last 50 years due to changes in reindeer husbandry methods; machinery making herding dogs largely redundant. Typical to human CE in the North has been the relatively benign nature of the disease compared with CE caused by E. granulosus sensu stricto. The metacestodes in humans and in the natural cervid hosts predominantly appear in the lungs. The causative agents have been identified as EG mitochondrial genotypes G8 and G10, now together with G6 (camel), G7 (pig) and G9 genotypes constituting the Echinococcus canadensis species. Based on recent findings in reindeer in Yakutia, G6 might also be recognised among cervid genotypes. The geographical distribution of both G8 and G10 is circumpolar, with G10 currently apparently more prevalent both in the Palearctic and Nearctic. Because of the disappearance of the working dog, E. canadensis in Fennoscandia is again highly dependent on the wolf, as it was before domestication of the dog. Pet and sled dogs, if their number further increases, may to a minor part participate in the life cycle. Human CE in the North was mostly diagnosed by mass chest tuberculosis radiography campaigns, which have been discontinued. PMID:26264249

  10. The current disequilibrium of North Cascade glaciers

    Pelto, Mauri S.

    2006-03-01

    Three lines of evidence indicate that North Cascade (Washington, USA) glaciers are currently in a state of disequilibrium. First, annual balance measured on nine glaciers yields a mean cumulative balance for the 1984-2004 period of -8.58 m water equivalent (w.e.), a net loss of ice thickness exceeding 9.5 m. This is a significant loss for glaciers that average 30-50 m in thickness, representing 18-32% of their entire volume.Second, longitudinal profiles completed in 1984 and 2002 on 12 North Cascade glaciers confirm this volume change indicating a loss of -5.7 to -6.3 m in thickness (5.0-5.6 m w.e.) between 1984 and 2002, agreeing well with the measured cumulative balance of -5.52 m w.e. for the same period. The change in thickness on several glaciers has been equally substantial in the accumulation zone and the ablation zone, indicating that there is no point to which the glacier can retreat to achieve equilibrium. Substantial thinning along the entire length of a glacier is the key indicator that a glacier is in disequilibrium.Third, North Cascade glacier retreat is rapid and ubiquitous. All 47 glaciers monitored are currently undergoing significant retreat or, in the case of four, have disappeared. Two of the glaciers where mass balance observations were begun, Spider Glacier and Lewis Glacier, have disappeared. The retreat since 1984 of eight Mount Baker glaciers that were all advancing in 1975 has averaged 297 m. These observations indicate broad regional continuity in glacial response to climate.

  11. North Sea oil and the environment

    This book, which is arranged in five sections, provides an historical record of the development of North Sea oil and gas over the past twenty years and records the lessons learnt from this experience. This first section provides an introductory framework to the three main themes, namely resources, environment and development. Section 2 is primarily concerned with the economic and social consequences of oil related development at two levels; firstly on the national economy and secondly the impact on local communities. Section 3 deals with impacts upon the physical environment and introduces the statutory land use planning system in Scotland. The Scottish approach to environmental assessment is reviewed and the need for mitigation by design explored. Section 4 examines specific field developments, and reviews the statutory controls and international initiatives regulating the extent of environmental disturbance and pollution from offshore operations. The effects of oil spillage and submarine pipelines on the environment and their impact on the fishing industry is followed by a discussion on the decommissioning and abandonment of offshore installations. Section 5 deals with the role and value of hazard and risk analysis in the siting, layout and safety zoning of onshore facilities and develops a case study on a major fractionation facility. The means of mitigating acute and chronic environmental risks are considered. A postscript provides a range of past comments and criticisms and finally draws some conclusions on the performance of environmental management and North Sea oil development. The North Sea oil and gas development experience proves that with wisdom, forethought and goodwill, industrial exploiters of natural resources can operate economically within legislative, policy, scientific, technical and design parameters without causing long-term irreversible environmental damage.

    2013-01-01

    The present paper is an attempt to analyze the status of gender inequality in North East India using various indicators based on secondary data. The study reveals that the northeast is better off than that of the nation as a whole in terms of gender equality. However inequality between women and men exists in the region in spite of the predominance of various ethnic groups who by and large do not believe in sex discrimination. The study reveals that women are relatively disempowered and enjoy...

  13. Millennial changes in North Atlantic oxygen concentrations

    Hoogakker, B. A. A.; Thornalley, D. J. R.; Barker, S.

    2016-01-01

    Glacial-interglacial changes in bottom water oxygen concentrations [O2] in the deep northeast Atlantic have been linked to decreased ventilation relating to changes in ocean circulation and the biological pump (Hoogakker et al., 2015). In this paper we discuss seawater [O2] changes in relation to millennial climate oscillations in the North Atlantic over the last glacial cycle, using bottom water [O2] reconstructions from 2 cores: (1) MD95-2042 from the deep northeast Atlantic (Hoogakker et al., 2015) and (2) ODP (Ocean Drilling Program) Site 1055 from the intermediate northwest Atlantic. The deep northeast Atlantic core MD95-2042 shows decreased bottom water [O2] during millennial-scale cool events, with lowest bottom water [O2] of 170, 144, and 166 ± 17 µmol kg-1 during Heinrich ice rafting events H6, H4, and H1. Importantly, at intermediate depth core ODP Site 1055, bottom water [O2] was lower during parts of Marine Isotope Stage 4 and millennial cool events, with the lowest values of 179 and 194 µmol kg-1 recorded during millennial cool event C21 and a cool event following Dansgaard-Oeschger event 19. Our reconstructions agree with previous model simulations suggesting that glacial cold events may be associated with lower seawater [O2] across the North Atlantic below ˜ 1 km (Schmittner et al., 2007), although in our reconstructions the changes are less dramatic. The decreases in bottom water [O2] during North Atlantic Heinrich events and earlier cold events at the two sites can be linked to water mass changes in relation to ocean circulation changes and possibly productivity changes. At the intermediate depth site a possible strong North Atlantic Intermediate Water cell would preclude water mass changes as a cause for decreased bottom water [O2]. Instead, we propose that the lower bottom [O2] there can be linked to productivity changes through increased export of organic material from the surface ocean and its subsequent remineralization in the water column

  14. The Byronic Heroine of North and South

    Lisnäs, Stina

    2015-01-01

    This essay argues that the protagonist of Elizabeth Gaskell’s North and South (1855), Margaret Hale, is a Byronic heroine. The counter argument that any such comparison is impossible because of her sex is refuted and examples are given of how Margaret is not portrayed like the other young women of the novel. She rejects the female stereotype of the time and it is furthermore proved that she steps out of the passive role considered best suited for a female, and takes on the active one, becomin...

  16. The Big Flood: North Sea storm surge.

    McRobie, Allan; Spencer, Tom; Gerritsen, Herman

    2005-06-15

    In the 50 years since the catastrophic southern North Sea storm surge of 31 January-1 February 1953, there have been technological advances in the engineering of flood protection, increased understanding of physical processes in shallow seas and estuaries, and developments in the mathematical statistics of extreme events. This introductory paper reviews how the scientific understanding of surge events, their impacts and the human responses to them is evolving on many fronts, often across disciplinary boundaries. The question of how the long-term nature of the problem itself will be influenced by possible climate, land use and policy changes is addressed, along with their associated uncertainties.

  4. North Sea oil: fuel for the economy?

    The feverish hunt for the black gold that exerts such a potent influence on the world economy and world politics, is moving on. A giant semi-submersible oil drilling rig owned by Diamond Offshore Drilling, of Houston, Texas, is being towed from the North Sea to Australia, a voyage that takes three months. Another of the company's rigs has already been shifted from UK waters to the Black Sea, and the possibility of dismantling it and transporting the pieces overland to the Caspian, to drill off the coast of Azerbaijan, is being looked at. The emphasis in exploration and appraisal drilling is definitely shifting away from the UK continental shelf. (author)

  5. Expensive tidying up in the North Sea

    The Norwegian government has decided that the scrapped offshore installations in the North Sea must be removed and brought to land for material recovery. This decision comprises fourteen steel platforms and the superstructure of the Ekofisk tank. By 2013, eleven platforms and waste material derived from drilling as well as rubbish on the sea floor around the installations must be removed. Until now platforms have been removed by first being dismounted at sea and then transported to land in pieces. The article describes a new transportation method proposed by a Norwegian company in which the removal is done in one operation

    2011-06-01

    Full Text Available The study assesses the spatio-temporal land use and land cover changes between 1986 and 2000 for the whole Obio/Akpor Local Government Area of Rivers State, Nigeria covering about 270.86 km2. Landsat images of 30 m × 30 m resolution of both 1986 and 2000 were used whereby seven land use types were detected and captured as polygons (shapefiles in Arcview 3.3 version after the images have been geo-rectified. The land use types include farmland, built up area, water, sparse vegetation, primary forest, secondary forest and mangrove. The area in square kilometers of each land use type in each year was calculated and thereafter the change was determined by subtracting the area of the same land use type in 1986 from 2000 and the percentage of change is therefore calculated. In addition, the probability of change of twenty years was also determined from one land use type to another using Markovian Transition Estimator (MTE from IDRISI Andes. The study reveals that farmland, mangrove, primary forest and sparse vegetation reduced over time by 45.34, 37.06, 43.06 and 8.09%, respectively while secondary forest, built up area and water increased by 5.88, 74.55 and 3.43%, respectively. It is also projected by MTE that in 2020 farmland has the probability of 0.570 (57% of changing to secondary forest and 0.154 (15.4% of changing to built up area. Primary forest has the probability of 0.186 (18.6% to change to built up area. It is recommended among others that laws should be promulgated to prevent unlawful expansion of construction of any form and that the people in the communities in the study area should be enlightened and educated on the effects of deforestation on the environment.

  10. Toxocariasis in North America: a systematic review.

    Rachel M Lee

    2014-08-01

    Full Text Available Toxocariasis is an important neglected tropical disease that can manifest as visceral or ocular larva migrans, or covert toxocariasis. All three forms pose a public health problem and cause significant morbidity in areas of high prevalence. To determine the burden of toxocariasis in North America, we conducted a systematic review of the literature following PRISMA guidelines. We found 18 articles with original prevalence, incidence, or case data for toxocariasis. Prevalence estimates ranged from 0.6% in a Canadian Inuit community to 30.8% in Mexican children with asthma. Commonly cited risk factors included: African-American race, poverty, male sex, and pet ownership or environmental contamination by animal feces. Increased prevalence of Toxocara spp. infection was linked in a group of case control studies conducted in Mexico to several high risk groups including waste pickers, asthmatic children, and inpatient psychiatry patients. Further research is needed to determine the true current burden of toxocariasis in North America; however the prevalence estimates gathered in this review suggest that the burden of disease is significant.

  11. The bentonite industry in North America

    The Canadian Nuclear Fuel Waste Management Program is studying a concept for the disposal of nuclear fuel waste at a depth of 500 to 1000 m below the surface in stable crystalline rock of the Canadian Shield. The waste containers would be surrounded by a clay-based buffer material, composed of equal proportions of bentonite clay and silica sand. In the reference disposal concept, some 1.9 x 105 Mg of used fuel would be emplaced. This would require 2.5 x 106 Mg of bentonite. A review of the bentonite industry in North America was carried out to establish the availability of sufficient high-quality material. There are proven reserves of sodium bentonite clay in excess of 1.5 x 108 Mg, and vast supplies are known to exist but not yet proven. The Canadian conceptual disposal vault would require 6 x 104 Mg of sodium bentonite each year for 40 years. The bentonite industry of North America has an installed annual production capacity of 2 x 107 Mg. A disposal vault would therefore require approximately 2% of the industry capacity. A number of commercial products have been screened for potential suitability for use as a component of the buffer. Ten currently marketed bentonite products have been identified as meeting the initial quality standards for the buffer, and two non-commercial bentonites have been identified as having the potential for use in a disposal vault.

The involvement of students in the political arena in the region is mostly organized through regional (ethnic organizations.The larger context of such political process is decentralisation, which make religional resource  resources dominated by the state. At the same time competition among local elites and ethnic groups flourish. This is the main background of a new formation of group interests in local level –-including local university students-- to gain group advantages. The case of Ternate, North Maluku, is an example of how groups of students organize their practical interests in the arena of politics by exploiting youth associations and ethnic organizations. Artikel ini mengkaji tentang politik yang diartikulasikan oleh kalangan mahasiswa dalam percaturan politik lokal di Ternate, Maluku Utara.

  13. The enigmatic whale: the North Atlantic humpback

    Tim D Smith

    2013-10-01

    Full Text Available We know more about the North Atlantic humpback whale (Megaptera novaeangliae than we do for virtually any other cetacean, yet attempts to use this information to describe the status of the populations in this ocean basin have not proven satisfactory. The North Atlantic humpback has been the subject of extensive research over the past few decades, resulting in a substantial amount of knowledge about what has proven to be a species with a very complex life history and population structure. While several population models have been developed to integrate the available information, the data overall are not well described by any of the models. This has left considerable uncertainty about population status, and has raised questions about the interpretation of some of the data. We describe 7 specific areas where puzzling or ambiguous observations have been made; these require closer attention if population status is to be determined. These areas raise several fundamental questions, including: How many breeding populations are there? How much do the populations mix on the feeding grounds? How has the distribution of animals on both feeding and breeding grounds changed? We identify additional research needed to address the 7 areas and these questions in particular, so that population status might be determined.

  14. Petroleum developments in North Africa in 1979

    Nicod, M.A.

    1980-11-01

    In the 6 countries covered by this report, the extent of valid petroleum rights, seismic work, and drilling was nearly the same as in 1978. The success rate of wildcat drilling decreased slightly, to 28% (33% in 1978), with 26 oil or gas discoveries. In southwestern Tunisia, the Amoco Sabrina Nord 1 tested 930 bbl of 39/sup 0/ APl oil from Cambrian-Ordovician sandstones - the first oil to come from lower Paleozoic rocks in Tunisia. First commercial oil from Cambrian-Ordovician rocks in western Libya was discovered by Agip A1-NC40 which flowed 1,400 b/d. Highlight of the year in North Africa was in the interior basin of Sudan where the Chevron Abu Gabra 1 tested 900 BOPD of 40/sup 0/ APl oil from Cretaceous rocks; 2 other wells, spudded in late 1979 in the same area, have tested 3,200 and 7,300 b/d, respectively, in early 1980. Discovery well of the interior basin was Chevron Unity 1 which tested small amounts of oil in 1978. Oil production in North Africa in 1979 averaged 3,939,500 b/d compared with 3,802,800 b/d in 1978, an increase of 3.6%.

  15. North Sea focus on radwaste disposal

    At the recent North Sea Conference in the Netherlands possible future strategies for managing radioactive waste (radwaste) proved to be a contentious issue. Several of its North Sea littoral neighbours sought a categorical assurance that the UK would forego the option of constructing a subterranean radwaste repository which though accessed from land, extends under the coastline, or a sub-seabed facility reached from an offshore structure. It was pointed out that the UK has no present plans for such a radwaste repository. However, sub-seabed designs as a possibility for future repositories were not ruled out. NIREX has decided to concentrate its exploration work at two sites -Sellafield and Dounreay. Both sites are coastal locations and the government is aware that detailed geological exploration may favour extension of a radwaste repository beyond the shoreline, even if initially developed entirely on land. The design of such a radioactive waste repository is outlined. The position of NIREX and the Radioactive Waste Management Advisory Committee is discussed. (author)

  16. The North Sea: Satellite colour atlas

    Holligan, P. M.; Aarup, T.; Groom, S. B.

    Satellite imagery of the North Sea from the Coastal Zone Color Scanner (CZCS) shows complex seasonal changes in the optical and biological properties of surface waters, features which have not been resolved, hitherto, through direct observations from ships. Selected scenes for the period 1979-1986, presented as single band (channel 3), colour composite (channels 1 + 2 + 3) and chlorophyll (channels 1/3 or 2/3) images, are used to demonstrate the relative surface distributions between February and October of suspended sediments, coccolithophores and plant pigments. Comparison are made also with sea surface temperature images from the Advanced Very High Resolution Radiometer (AVHRR). Quantitative evaluation of the CZCS data is restricted by a lack of contemporary in situ optical and biological measurements. However, chlorophyll and Secchi disc distributions, determined by measurements from research ships have been compared qualitatively with images from the Southern Bight (13 May 1986) and for the east central North Sea (24 August 1984 and 24 October 1985). Mini series of CZCS images are presented to show the annual coccolithophore blooms, the development of the spring bloom in the Skagerrak, June 1983 and summer chlorophyl distributions in the German Bight.

  17. Phytoplankton Bloom in North Sea off Scotland

    2008-01-01

    The northern and western highlands of Scotland were still winter-brown and even dusted with snow in places, but the waters of the North Sea were blooming with phytoplankton on May 8, 2008, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite passed over the region and captured this image. The tiny, plant-like organisms swirled in the waters off the country's east coast, coloring the shallow coastal waters shades of bright blue and green. Phytoplankton are tiny organisms--many are just a single cell--that use chlorophyll and other pigments to capture light for photosynthesis. Because these pigments absorb sunlight, they change the color of the light reflected from the sea surface back to the satellite. Scientists have used observations of 'ocean color' from satellites for more than 20 years to track worldwide patterns in phytoplankton blooms. Phytoplankton are important to the Earth system for a host of reasons, including their status as the base of the ocean food web. In the North Sea, they are the base of the food web that supports Scotland's commercial fisheries, including monkfish and herring. As photosynthesizers, they also play a crucial role in the carbon cycle, removing carbon dioxide from the atmosphere. Some oceanographers are concerned that rising ocean temperatures will slow phytoplankton growth rates, harming marine ecosystems and causing carbon dioxide to accumulate more rapidly in the atmosphere.

  18. Lithospheric layering in the North American craton.

    Yuan, Huaiyu; Romanowicz, Barbara

    2010-08-26

    How cratons-extremely stable continental areas of the Earth's crust-formed and remained largely unchanged for more than 2,500 million years is much debated. Recent studies of seismic-wave receiver function data have detected a structural boundary under continental cratons at depths too shallow to be consistent with the lithosphere-asthenosphere boundary, as inferred from seismic tomography and other geophysical studies. Here we show that changes in the direction of azimuthal anisotropy with depth reveal the presence of two distinct lithospheric layers throughout the stable part of the North American continent. The top layer is thick ( approximately 150 km) under the Archaean core and tapers out on the surrounding Palaeozoic borders. Its thickness variations follow those of a highly depleted layer inferred from thermo-barometric analysis of xenoliths. The lithosphere-asthenosphere boundary is relatively flat (ranging from 180 to 240 km in depth), in agreement with the presence of a thermal conductive root that subsequently formed around the depleted chemical layer. Our findings tie together seismological, geochemical and geodynamical studies of the cratonic lithosphere in North America. They also suggest that the horizon detected in receiver function studies probably corresponds to the sharp mid-lithospheric boundary rather than to the more gradual lithosphere-asthenosphere boundary.

  19. The 1991 North Dakota Legislature--Agricultural Update

    Murphy, Paul C.; Sheets, Jeff L.; Saxowsky, David M.

    1991-01-01

    The 1991 North Dakota Legislature extensively considered economic development. Growing North Dakota, perhaps one of the most comprehensive proposals, was not adopted until near the end of the session. This program encourages diversification and industrialization of North Dakota agriculture, as well as provides continued funding for several agricultural programs, including the beginning farmer program. The legislators acted to protect groundwater resources and established a Northwestern Area W...

    Hodur, Nancy M.; Dean A. BANGSUND; Leistritz, F. Larry

    2004-01-01

    Recreational activities related to North Dakota's wealth of natural resources are well-established in North Dakota. In recent years, North Dakota's abundant resources have attracted visitors from around the country and the world. In addition to providing recreational activities for residents and visitors alike, natural resource-based tourism is a basic sector that may have considerable potential for creating economic opportunities in rural areas. Recognition of the potential importance of res...

  3. THE STATE RESPONSIBILITY OF CHINA FOR THE NORTH KOREAN REFUGEES

    2008-01-01

    The North Korean refugee crisis merits significant international attention because these people are the most vulnerable group and the silent victims in our international community of the last few decades. Their government does not have the ability to protect its citizens. It is a question of State Sovereignty as to whether China recognizes North Koreans as refugees or not and provides them with humanitarian relief. China argues that North Koreans are not refugees, forcibly repatrates them,...

  4. The United Nations monitoring system - applications for North Korea

    Shinn, Richard J.

    1995-01-01

    In October 1994 the United States and North Korea agreed on international oversight of the North Korean nuclear program by the International Atomic Energy Agency (IAEA). To verify North Korean cooperation, the IAEA has been authorized to use electronic monitoring techniques similar to those employed by the United Nations Special Commission on Iraq (UNSCOM). For a monitoring effort to be effective, it must be equipped with a communications system that can withstand the demanding political and ...

  5. Gender in Transition: The Case of North Korea

    Stephan Haggard; Marcus Noland

    2012-01-01

    This paper uses a survey of 300 North Korean refugees to examine the experience of women in North Korea's fitful economic transition. Like other socialist states, North Korea has maintained a de jure commitment to women's rights. However, we find that women have been disproportionately shed from state-affiliated employment and thrust into a market environment characterized by weak institutions and corruption. As a result, the state and its affiliated institutions are increasingly populated by...

  6. Sanctioning North Korea: The Political Economy of Denuclearization and Proliferation

    Stephan Haggard; Marcus Noland

    2009-01-01

    As a small country dependent on foreign trade and investment, North Korea should be highly vulnerable to external economic pressure. In June 2009, following North Korea's second nuclear test, the UN Security Council passed Resolution 1874, broadening existing economic sanctions and tightening their enforcement. However, an unintended consequence of the nuclear crisis has been to push North Korea into closer economic relations with China and other trading partners that show little interest in ...

  7. Study on Chinese Impact on Economic Sanctions against North Korea

    2011-01-01

    As the U.S. and South Korea expressed solidarity in blaming North Korea for its attack on the South Korean warship Cheonan and in imposing further sanctions on North Korea, global attention is now focused on China with regard to whether it will cooperate in inflicting punitive measures on its ally. Despite the worsening cleavages between China and North Korea since October 2006 when the latter tested its nuclear weapons, this study shows that their relations has remained robust in the economi...

  8. The (Non) Impact of UN Sanctions on North Korea

    Marcus Noland

    2009-01-01

    This study finds that North Korea's nuclear test and the imposition of UN Security Council sanctions have had no perceptible effect on North Korea's trade with its two largest partners, China and South Korea. Before North Korea conducted an underground nuclear test, it was widely believed that such an event would have cataclysmic diplomatic ramifications. However, beginning with visual inspection of data and ending with time-series models, no evidence is found to support the notion that these...

  9. North Korea: Fading Totalitarianism in the Hermit Kingdom

    Katzeff Silberstein, Benjamin

    2010-01-01

    North Korea is perceived by many as one of the most totalitarian societies of modern time. But in the wake of the economic collapse of the 1990s, North Korean totalitarianism has grappled with new conditions. This paper examines how the country’s totalitarian character has been upheld through the institutional changes instigated by the economic collapse and subsequent famine in the country. It strives to answer whether today’s North Korea should still be characterized as a totalitarian societ...

  11. Mechanisms and predictability of North Atlantic - European Climate

    Pohlmann, H.

    2005-01-01

    This study investigates the mechanisms of North Atlantic-European climate using atmosphere general circulation models (AGCMs). Experiments with the AGCM ECHAM4, in which the sea surface temperature (SST) forcing is restricted to either the Atlantic or the Indo-Pacific oceans, show that both oceanic regions have an influence on North Atlantic-European climate in winter. In the experiment with SST forcing restricted to the Indo-Pacific oceans the atmospheric response projects on the North Atlan...

  12. Compression of the North Hemisphere derived from space geodesy

    金双根; 朱文耀

    2003-01-01

    The convergent and divergent velocities of active plate boundaries in the North Hemisphere are obtained with space geodetic data. The relative motions of adjacent plates in north-south direction are almost convergent; the spreading rates of the north mid-Atlantic ridge are smaller than the south mid-Atlantic ridge; the closed differences of the baseline length rates between stations on different plates along the latitudinal circle of 7.7(, 23.3o, 34.8o, 42.0o and 51.0o are all negative. All these show that the North Hemisphere is a compressive hemisphere.

  13. Migration of western mackerel to the North Sea 1973 - 1988

    1989-01-01

    The latest years, it is evident that most of the mackerel present in the North Sea belongs to the Western stock, since the yearly catches by far exceed the presumed size of the North Sea stock. The Norwegian tagging data have been revised to obtain estimates of the percentage of Western mackerel in the catches in the North Sea. By combining these data with the distribution of catches, a reasonable estimate of the migration of the Western mackerel to the North Sea may be o...

  14. North Atlantic SST anomalies and the cold North European weather events of winter 2009/10 and December 2010

    Buchan, Jian; Hirschi, Joel; Blaker, Adam; Sinha, Bablu

    2014-01-01

    Northern Europe experienced consecutive periods of extreme cold weather in the winter of 2009/2010 and in late 2010. These periods were characterised by a tripole pattern in North Atlantic sea surface temperature (SST) anomalies and exceptionally negative phases of the North Atlantic Oscillation (NAO). A global Ocean-Atmosphere General Circulation Model (OAGCM) is used to investigate the ocean’s role in influencing North Atlantic and European climate. Observed SST anomalies are used to force ...

  15. The recent warming trend in North Greenland

    Orsi, Anais; Kawamura, Kenji; Masson-Delmotte, Valerie; Landais, Amaelle; Severinghaus, Jeff

    2015-04-01

    The arctic is the fastest warming region on Earth, but it is also one where there is little historical data. Although summer warming causes melt, the annual temperature trend is dominated by the winter and fall season, which are much less well documented. In addition, the instrumental record relies principally on coastal weather stations, and there are very few direct temperature observations in the interior dating back more than 30 years, especially in North Greenland, where the current warming trend is the largest. Here, we present a temperature reconstruction from NEEM (51°W, 77°N), in North Greenland, for the last 100 years, which allows us to put the recent trend in the context of the longer term climate. We use a combination of two independent proxies to reconstruct the temperature history at NEEM: borehole temperature and inert gas isotope measurements in the firn. Borehole temperature takes advantage of the low temperature diffusivity of the snow and ice, which allows the temperature history to be preserved in the ice for several centuries. Temperature gradients in the firn (old snow above the ice) influence the gas isotopic composition: thermal fractionation causes heavy isotopes to concentrate on the cold end of the firn column. We measured the isotopes of inert gases (N2, Ar and Kr), which have a constant atmospheric composition through time, and use the thermal fractionation signal as an additional constraint on the temperature history at the site. We find that NEEM has been warming by 0.86±0.22°C/decade over the past 30 years, from -28.55±0.29°C for the 1900-1970 average to -26.77±0.16°C for the 2000-2010 average. The warming rate at NEEM is similar to that of Greenland Summit, and confirms the large warming trends in North Greenland (polar amplification) and high altitude sites (tropospheric rather than surface warming). Water isotopes show that the recent past has not met the level of the 1928 anomaly; but the average of the past 30 years has

  16. 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

  17. Cortinarius section Sanguinei in North America.

    Niskanen, Tuula; Liimatainen, Kare; Ammirati, Joseph F; Hughes, Karen

    2013-01-01

    The North American species of Cortinarius section Sanguinei were studied using morphological characters and ITS and RPB2 sequence data. Several type collections also were examined. Four species were identified: C. harrisonii sp. nov, C. neosanguineus sp. nov., C. sanguineus and C. sierraensis comb. nov. Of these, C. sanguineus also occurs in Europe together with C. puniceus, a fifth member of the section. Typical features of these species include ± red, fairly small basidiomata, stipe basal mycelium often with yellow to reddish yellow tints, amygdaloid to ellipsoid spores, and aniline-red lamellar trama and pileipellis hyphae when mounted in KOH. Two other species with red lamellae C. marylandensis comb. nov. and C. smithii stat. nov. & nom. nov. also are discussed. PMID:22962360

  18. The North Polar Spur and Aquila Rift

    Sofue, Yoshiaki

    2014-01-01

    Soft X-ray intensity at 0.89 keV along the North Polar Spur is shown to follow the extinction law due to the interstellar gas in the Aquila Rift by analyzing the ROSAT archival data, which proves that the NPS is located behind the rift. The Aquila-Serpens molecular clouds, where the X-ray optical depth exceeds unity, are shown to have a mean LSR velocity of v=7.33 +/- 1.94 km/s, corresponding to a kinematic distance of r=0.642 +/- 0.174 kpc. Assuming a shell structure, a lower limit of the distance to NPS is derived to be 1.01 +/- 0.25 kpc, with the shell center being located farther than 1.1 kpc. Based on the distance estimation, we argue that the NPS is a galactic halo object.

  19. Oral literary traditions in North Sumatra

    Clara Brakel-Papenhuyzen

    2010-04-01

    Full Text Available This article deals with traditional literature of the Pakpak-Dairi and Karo peoples in North Sumatra, who are speakers of closely related Batak languages and have many common features in their language and culture. Their traditional life-style, based on agriculture and the use of forest products, requires the regular performance of community rituals featuring songs, dance, music and other oral traditions including storytelling. The songs, prayers, and stories belonging to their literary tradition have characteristic features that are intimately connected with the social context in which they are created and performed. Karo and Pakpak-Dairi oral genres often contain information about the natural environment, local customs and religious concepts. They may also reflect perceptions of relationships with neighbouring groups, such as the Minangkabau and the Malays who live in the coastal areas.

  20. Submarine pipelines and the North Sea environment

    The function and design of pipelines for use on the United Kingdom continental shelf are described. Environmental influences which can threaten the integrity of seabed pipelines in the North Sea include hydrodynamic forces due to residual, tidal and wave currents, the nature of seabed sediments and corrosion by seawater. Damage may be caused to pipelines by interaction with vessel anchors and with fishing gear. Special care has to be taken over the selection of the general area for the landfall of a pipeline and the engineering of the installation where the pipeline comes ashore. Trenching and other protection techniques for pipelines are discussed together with hydrostatic testing and commissioning and subsequent inspection, maintenance and repair. (UK)

  1. North Fork Feather River Erosion Control Program

    PG and E, an investor owned gas and electric utility serving northern and central California, has been engaged since 1984 in the development and implementation of a regional erosion control program for the 954 square mile northern Sierra Nevada watersheed of the East Branch of the North Fork Feather River in Plumas County, California. PG and E entered into an agreement with 13 governmental agencies and a number of private landowners using Coordinated Resource Management and Planning: to cooperatively develop, fund and implement the program. The group has completed several field projects and has a number of additional projects in various stages of development. This paper reports that the program provides multiple environmental and economic benefits including reduction of soil erosion and sedimentation, improved fisheries, enhancement of riparian habitat, increased land values, improved recreation opportunities, and preservation of watershed resources

  2. Pediatric liver transplantation: a North American perspective.

    Kerkar, Nanda; Lakhole, Arathi

    2016-08-01

    Liver transplantation (LT) is an important component in the therapeutic armamentarium of managing end-stage liver disease. In North American children, biliary atresia remains the most common indication for LT compared to hepatitis C in adults, while hepatoblastoma is the most common liver tumor requiring LT, versus Hepatocellular carcinoma in adults. Rejection, lymphoproliferative disease, renal insufficiency, metabolic syndrome, recurrent disease, 'de novo' autoimmune hepatitis and malignancy require careful surveillance and prompt action in adults and children after LT. In children, specific attention to EBV viremia, growth, development, adherence and transition to the adult services is also required. Antibody mediated rejection and screening for donor specific antibodies is becoming important in managing liver graft dysfunction. Biomarkers to identify and predict tolerance are being developed. Machine perfusion and stem cells (iPS) to synthesize organs are generating interest and are a focus for research. PMID:26982346

  3. 2005 the North American Solar Challenge

    Dan Eberle

    2008-12-22

    In July 2005 the North American Solar Challenge (NASC) featured university built solar powered cars ran across the United States into Canada. The competition began in Austin, Texas with stops in Weatherford, Texas; Broken Arrow, Oklahoma; Topeka, Kansas; Omaha, Nebraska; Sioux Falls, South Dakota, Fargo, North Dakota; Winnipeg, Manitoba; Brandon, Manitoba; Regina, Saskatchewan; Medicine Hat, Alberta; mainly following U.S. Highway 75 and Canadian Highway 1 to the finish line in Calgary, Alberta, Canada, for a total distance of 2,500 miles. NASC major sponsors include the U.S. Department of Energy (DOE), Natural Resources Canada and DOEs National Renewable Energy Laboratory. The event is designed to inspire young people to pursue careers in science and engineering. NASCs predecessors, the American Solar Challenge and Sunrayce, generally have been held every two years since 1990. With each race, the solar cars travel faster and further with greater reliability. The NASC promotes: -Renewable energy technologies (specifically photovoltaic or solar cells) -Educational excellence in science, engineering and mathematics -Creative integration of technical and scientific expertise across a wide-range of disciplines -Hands-on experience for students and engineers to develop and demonstrate their technical and creative abilities. Safety is the first priority for the NASC. Each team put its car through grueling qualifying and technical inspections. Teams that failed to meet the requirements were not allowed participate. During the race, each team was escorted by lead and chase vehicles sporting rooftop hazard flashers. An official observer accompanied each solar car team to keep it alert to any safety issues.

  4. Soil indigenous knowledge in North Central Namibia

    Prudat, Brice; Bloemertz, Lena; Kuhn, Nikolaus J.

    2016-04-01

    Mapping and classifying soils is part of an important learning process to improve soil management practices, soil quality and increase productivity. In order to assess soil quality improvement related to an ongoing land reform in North-Central Namibia, the characteristics that determine soil quality in the local land use context were determined in this study. To do so, we collated the indigenous soil knowledge in North-Central Namibia where the Ovakwanyama cultivate pearl millet for centuries. Local soil groups are defined mostly based on their productivity potential, which varies depending on the rainfall pattern. The morphological criteria used by the farmers to differentiate the soil groups (colour, consistence) were supported by a conventional analysis of soil physical and chemical properties. Now, they can be used to develop a soil quality assessment toolbox adapted to the regional use. The characteristics of the tool box do not directly indicate soil quality, but refer to local soils groups. The quality of these groups is relatively homogenous at the local scale. Our results show that understanding of indigenous soil knowledge has great potential to improve soil quality assessment with regards to land use. The integration of this knowledge with the conventional soil analysis improves the local meaning of such a "scientific" assessment and thus facilitates dialog between farmers and agronomists, but also scientists working in different regions of the world, but in similar conditions. Overall, the integration of indigenous knowledge in international classification systems (e.g. WRB) as attempted in this study has thus a major potential to improve soil mapping in the local context.

  5. Compaction of North-sea chalk

    Keszthelyi, Dániel; Dysthe, Dag Kristian; Jamtveit, Bjørn

    2014-05-01

    The Ekofisk field is the largest petroleum field in the Norwegian North Sea territory where oil is produced from chalk formations. Early stage of oil production caused considerable changes in pore fluid pressure which led to a reservoir compaction. Pore collapse mechanism caused by the dramatic increase of effective stress, which in turn was caused by the pressure reduction by hydrocarbon depletion, was early identified as a principal reason for the reservoir compaction (Sulak et al. 1991). There have been several attempts to model this compaction. They performed with variable success on predicting the Ekofisk subsidence. However, the most of these models are based on empirical relations and do not investigate in detail the phenomena involved in the compaction. In sake of predicting the Ekofisk subsidence while using only independently measurable variables we used a chalk compaction model valid on geological time-scales (Japsen et al. 2011) assuming plastic pore-collapse mechanism at a threshold effective stress level. We identified the phenomena involved in the pore collapse. By putting them in a sequential order we created a simple statistical analytical model. We also investigated the time-dependence of the phenomena involved and by assuming that one of the phenomena is rate-limiting we could make estimations of the compaction rate at smaller length-scales. By carefully investigating the nature of pressure propagation we could upscale our model to reservoir scale. We found that the predicted compaction rates are close enough to the measured rates. We believe that we could further increase accuracy by refining our model. Sulak, R. M., Thomas, L. K., Boade R. R. (1991) 3D reservoir simulation of Ekofisk compaction drive.

  6. Power production via North Sea Hot Brines

    Traditionally the power demand of offshore oil platforms is delivered by on-platform gas turbines. Natural gas to fuel these turbines is usually separated from the produced oil. However, in ageing fields as oil production declines so does the associated gas. Ultimately gas supply becomes insufficient; in order to continue producing fuel is imported at great expense. This study proposes the power demand of a platform could be met or supplemented by an on-platform ORC (organic Rankine cycle ) fuelled by coproduced hot brines. This could extend the operating life of oil platforms and reduce both cost and emissions. The potential power output of an ORC is modelled for fields in the North Sea's Brent Province. Results show 6 fields have the potential to generate more than 10 MW via an organic Rankine cycle fuelled by hot brines, with a maximum of 31 MW predicted for the Ninian field. Analysis of simulations for the Eider field shows that ORC plants can scale to size constraints. The cost of a 10 MW ORC is compared to cost of continued use of gas turbines. Payback times of between 3.09 and 4.53 years are predicted for an ORC, without accounting for greenhouse gas emissions levies. - Highlights: • We model organic Rankine cycles fuelled by hot brines produced in the North Sea. • Organic Rankine cycles could provide all an off-shore platform's power demand. • 6 fields in the Brent province have the potential to produce >10 MW via an ORC system. • Payback time calculated for a 10 MW organic Rankine cycle is 3.09–4.53 years

  7. Extreme Storm Surges in the North Sea

    Goennert, G.; Buß, Th.; Mueller, O.; Thumm, S.

    2009-04-01

    Extreme Storm Surges in the North Sea Gabriele Gönnert, Olaf Müller, Thomas Buß and Sigrid Thumm Climate Change will cause a rise of the sea level and probably more frequent and more violent storm surges. This has serious consequences for the safety of people as well as for their values and assets behind the dikes. It is therefore inevitable to first assess how sea level rise and an extreme storm surge event designes. In a second step it is possible to determine the risk for specific locations and develop strategies. The Project XtremRisk - Extreme Storm Surges at the North Sea Coast and in Estuaries. Risk calculation and risk strategies, funded by the German Federal Government will help answering these questions. The „Source-Pathway-Receptor" Concept will be used as a basis for risk analysis and development of new strategies. The Project offers methods to assess the development of extreme events under the conditions of today. Under conditions reflecting the climate change it will be tried to design an extreme event. For these three main points will be considered: a) Analysis and calculation of each factor, which produce a storm surge and its maximum level occurring in the last 100 years. These are: - maximum surge level: surge (due to the wind), - influence of the tide and the interaction between surge and tide, - influence of external surges , b) The hydrodynamics of a storm surge cause nonlinear effects in the interaction of the named factors. These factors and effects will both be taken into account to calculate the magnitude of the extreme storm surge. This step is very complex and need additional examination by numerical models. c) Analysis of the different scenarios to mean sea level rise and to the increase of wind speed due to the climate change. The presentation will introduce methods and show first results of the analysis of extreme events and the mean sea level rise.

  8. Frequency of marine heatwaves in the North Atlantic and North Pacific since 1950

    Scannell, Hillary A.; Pershing, Andrew J.; Alexander, Michael A.; Thomas, Andrew C.; Mills, Katherine E.

    2016-03-01

    Extreme and large-scale warming events in the ocean have been dubbed marine heatwaves, and these have been documented in both the Northern and Southern Hemispheres. This paper examines the intensity, duration, and frequency of positive sea surface temperature anomalies in the North Atlantic and North Pacific Oceans over the period 1950-2014 using an objective definition for marine heatwaves based on their probability of occurrence. Small-area anomalies occur more frequently than large-area anomalies, and this relationship can be characterized by a power law distribution. The relative frequency of large- versus small-area anomalies, represented by the power law slope parameter, is modulated by basin-scale modes of natural climate variability and anthropogenic warming. Findings suggest that the probability of marine heatwaves is a trade-off between size, intensity, and duration and that region specific variability modulates the frequency of these events.

  19. Scientific symposium on the North Sea quality status report 1993

    The Scientific Symposium on the 1993 North Sea quality Status Report took place in Ebeltoft, Denmark from 18 to 21 April 1994. The aim was to bring together scientists, researchers and administrators from governments, industries and environmental organizations from the countries around the North Sea in order to review new information which may supplements the 1993 North Sea Quality Status Report and to discuss the Quality Status Report and its possible implications. The 1993 North Sea Quality Status Report has been prepared by the North Sea Task force as a comprehensive statement of circulation patterns, inputs and dispersion of contaminants, ecological conditions and effects of human activities in the North Sea including the Skagerrak and the Kattegat. The programme of the Scientific Symposium on the 1993 North Sea Quality Status Report included 8 sessions for oral presentations, a poster session presenting the North Sea Task Force subregional reports and a poster session presenting individual posters. The headings of the sessions were as follows: Oceanography, Models and Remote Sensing; Ecosystem Structure; Contaminants -Distribution and Effects; Nutrients and Eutrophication Problems; Effects of Fishery; Habitats and Species; Management Implications; Conclusions and Recommendations. The proceedings includes a total of 45 contributed papers. (EG)

  20. Controls on hydrocarbon column-heights in the north-eastern North Sea

    Sollie, Ole Christian Engdal

    2015-01-01

    Knowledge about the controls on hydrocarbon column-heights is important in hydrocarbon exploration, as such column heights are the main controlling factor for in-place volumes of prospects. The north-eastern Viking Graben comprises an overpressured and a close to- normally pressured area, and commercial and sub-commercial discoveries as well as dry structures have been drilled in both areas. Both oil and gas is present in reservoirs in the study area and the aim ...

  1. North Pacific seasonality and the glaciation of North America 2.7 million years ago

    Haug, G. H.; Ganopolski, A.; Sigman, D. M.; Rosell-Mele, A.; G. E. A. Swann; R. Tiedemann; S. L. Jaccard; J. Bollmann; Maslin, M. A.; Leng, M. J.; Eglinton, G.;  ,

    2005-01-01

    In the context of gradual Cenozoic cooling, the timing of the onset of significant Northern Hemisphere glaciation 2.7 million years ago is consistent with Milankovitch’s orbital theory, which posited that ice sheets grow when polar summertime insolation and temperature are low. However, the role of moisture supply in the initiation of large Northern Hemisphere ice sheets has remained unclear. The subarctic Pacific Ocean represents a significant source of water vapour to boreal North America, ...

  2. The North Atlantic Oscillation: variability and interactions with the North Atlantic ocean and Artic sea ice

    Jung, T.

    2000-07-01

    The North Atlantic oscillation (NAO) represents the dominant mode of atmospheric variability in the North Atlantic region and describes the strengthening and weakening of the midlatitude westerlies. In this study, variability of the NAO during wintertime and its relationship to the North Atlantic ocean and Arctic sea ice is investigated. For this purpose, observational data are analyzed along with integrations of models for the Atlantic ocean, Arctic sea ice, and the coupled global climate system. From a statistical point of view, the observed NAO index shows unusually high variance on interdecadal time scales during the 20th century. Variability on other time scales is consistent with realizations of random processes (''white noise''). Recurrence of wintertime NAO anomalies from winter-to-winter with missing signals during the inbetween nonwinter seasons is primarily associated with interdecadal variability of the NAO. This recurrence indicates that low-frequency changes of the NAO during the 20th century were in part externally forced. (orig.)

  3. North American Ground Surface Temperature Histories: A Contribution to the PAGES2k North American Project

    Mareschal, J. C.; Jaume Santero, F.; Beltrami, H.

    2015-12-01

    Within the framework of the PAGES NorthAmerica2k project, three hundred and seventy three (373) North American temperature-depth profiles from boreholes deeper than 300 meters were analyzed for recent climate. To facilitate comparisons and examine the same time period, the profiles were truncated at 300 m. The ground surface temperature (GST) histories for the last 500 years were inverted from the subsurface temperature anomalies using singular value decomposition for a model of 10 temperature changes along time-intervals of increasing duration. The inversion retains four singular values and accounts for the data acquisition time difference. The reference surface temperature and geothermal gradient were estimated by linear regression to the deepest 100 meters with a 95% confidence interval. Additionally, a Monte-Carlo method was used to find the range of solutions within a maximum subsurface anomaly error determined by the root mean square between the model and the data. The GST history results for North America, given by the mean and 95% confidence interval, reveal in most cases, a warming up to 1°C - 2.5°C during the last 100-150 years.

  4. Nephrolithiasis in free-ranging North American river otter (Lontra canadensis) in North Carolina, USA.

    Niemuth, Jennifer N; Sanders, Charles W; Mooney, Charles B; Olfenbuttel, Colleen; DePerno, Christopher S; Stoskopf, Michael K

    2014-03-01

    The North American river otter (Lontra canadensis) serves as an indicator species for environmental monitoring, is prized as a valuable furbearer, and is a popular display animal in zoologic collections. Nephrolithiasis has been reported as a frequent problem in other free-ranging and captive otter species but is rarely reported in North American river otters. In this study, we compared the prevalence of nephrolithiasis diagnosed using routine gross pathologic examination techniques with the use of computed tomography (CT) of excised kidneys. We also evaluated whether otter nephroliths could be accurately classified by their CT densities, and we examined the renal tissue uric acid concentrations in free-ranging otters in North Carolina, USA. Kidneys were collected from carcasses of legally trapped, free-ranging animals. Nephroliths were observed in 16.2% of the individuals (n = 229). Associations were found between age and nephrolith status and between capture location and nephrolith status (P = 0.026 and < 0.001, respectively). Computed tomography Hounsfield unit density measurements were not useful in determining nephrolith chemical composition in this study. Renal tissue uric acid concentrations were similar across genders, age groups, and stone status. The chemical composition of the nephroliths was determined by scanning electron microscopy-energy dispersive X-ray spectroscopy to be calcium phosphate in the carbonate form. PMID:24712169

  6. 1992 North Dakota Economic Impact Study for the Uranium Mill Tailings Remedial Action Project, Belfield and Bowman, North Dakota

    The goal of the Uranium Mill Tailings Remedial Action (UMTRA) Project in North Dakota is to improve the environment and reduce the negative health effects associated with residual radioactive material (RRM) from the inactive processing sites at Belfield and Bowman, North Dakota. A secondary benefit of the UMTRA Project is economic gain. The 1992 North Dakota Economic Impact Study (NDEIS) analyzes the impact of the remedial actions at the inactive Belfield and Bowman processing sites and their associated vicinity properties. This analysis is based on the assumption that the state of North Dakota will provide 10 percent of the funding required for remediation. For every dollar the state of North Dakota invests in the Belfield and Bowman onsite portion of the UMTRA Project, it will realize $5.04 in gross labor income (i.e., gross labor income divided by the state's total funding requirement). For every dollar the state of North Dakota invests, it will realize a net return of $3.04 (i.e., net benefit divided by the state's total funding requirement). This reflects only labor expenditure and employment impact. ff state and local non-labor tax benefits were considered in the net economic benefit, North Dakota could receive significantly more than $3.04 for each dollar it invests. The UMTRA Project work at Belfield and Bowman will benefit the state of North Dakota. Benefits include a reduction in the negative health effects caused by low-level RRM, an improvement in the environment, and increased economic growth

  7. Surface Wind Observational Database in North Eastern North America: Quality Control Procedure and Climatological Variability

    Lucio-Eceiza, Etor E.; Fidel González-Rouco, J.; Navarro, Jorge; Hidalgo, Ángela; Conte, Jorge; Beltrami, Hugo

    2015-04-01

    This work summarizes the design and application of a Quality Control (QC) procedure for an observational surface wind database located in North Eastern North America. It also presents some insights of the long-term climatological variability over the region. The database consists of 527 sites (487 land stations and 40 buoys) with varying resolutions of hourly, 3 hourly and 6 hourly data, compiled from three different source institutions. The records span from 1940 to 2010 and cover an approximate spatial extension of 2.2 × 106 km2. The QC process is composed of different phases focused either on problems related with the providing source institutions or measurement errors. Due to the size of the data set, a great effort has been made on the automation of the procedures. A number of problems are associated with data management and data conventions: unification of measurement units and recording times due to the variety of institutional sources; detection of erroneous data sequence duplications within a station or among different ones; and detection of errors related with physically unrealistic data measurements. From the other hand there is a variety of treated instrumental errors: problems related with low variability, placing particular emphasis on the detection of unrealistic low wind speed records with the help of regional references; high variability related erroneous records; wind speed biases on week to monthly timescales and homogenization of wind direction records. As a result, around 1.7% of wind speed records and 0.4% of wind direction records have been deleted, making a combined total of 1.9% of removed records. Around 2.4% of wind direction data have been also corrected. The already quality controlled database allows for subsequent climatological analyses. The intra and inter decadal variability of the monthly surface wind field in such a vast and orographically complex region as the North Eastern North America is explored. Several decades of quality

  8. Ice Age Geomorphology of North America

    Wickert, A. D.; Anderson, R. S.; Mitrovica, J. X.; Picard, K.

    2012-12-01

    The Last Glacial Cycle in North America dramatically modified drainage patterns and geomorphology on a continental scale. As a consequence, the evolution of river systems holds information on the patterns of glaciation and isostatic response. This information can, in principle, be used to reconstruct the volumes of ice sheet sectors and eroded material by connecting the upstream ice sheets with stable isotope and other sedimentary records in offshore basins. Here we integrate this coupled geomorphic-hydrologic-glacial-sedimentary-paleoceanographic system to solve both the forward problem, how rivers evolve in response to Ice Age forcing, as well as the inverse problem, how fluvial systems record Quaternary history. The connections that define this system provide a link between climate and geomorphology that extends beyond the traditionally considered watershed-to-landscape scale by incorporating solid Earth deformations, large-scale shoreline migration, and the high amplitude changes in climate that drive the growth and decay of major ice sheets and water delivery to the bounding river systems. We address this continental scale problem using a valley-resolving drainage reconstruction that incorporates a realistic ice sheet history, a gravitationally self-consistent treatment of ice-age sea-level changes that includes shoreline migration, and precipitation and evapotranspiration retrodicted using general circulation model (GCM) runs. Drainage divides over the flat-lying North American interior migrate hundreds to thousands of kilometers in response to dynamic interactions between ice sheets and solid Earth response, and these changes coupled with post last glacial maximum (LGM) ice sheet melting drive high-amplitude variability in water and sediment discharge to the oceans. The Mackenzie River Delta records a sedimentary record produced by a highly non-eustatic sea level history and massive glacial sediment inputs routed along the axis that divided the Cordilleran

  9. Lethal domestic violence in eastern North Carolina.

    Gilliland, M G; Spence, P R; Spence, R L

    2000-01-01

    Strategies for preventing domestic violence can be tailored to a particular geographic or socioeconomic area if the patterns of domestic violence in the area are known. National statistics, although widely available, may not be applicable to a specific region. We reviewed homicide deaths in Eastern North Carolina between 1978 and 1999 to identify patterns in this rural area. Approximately 20% of the homicide deaths in eastern North Carolina are caused by intimate partners. Women accounted for 53% of the victims in 1976, similar to national figures but not rising to 72% as seen nationally in 1998. Latinos are an increasing presence in the area, but had only one recorded episode of lethal violence against an intimate partner. Gunshots accounted for most of the deaths (59% in men, 72% in women). Knowledge of such patterns can assist in selecting prevention strategies for this particular area. Over the last 25 years increasing attention has been devoted to domestic violence (DV), initially defined as abuse committed against a spouse, former spouse, fiancée, boy- or girlfriend, or cohabitant. As time has passed, the definition has been broadened to include other family members--elders, children, and siblings. The Centers for Disease Control and Prevention (CDC) now uses the term "intimate partner violence" for intentional emotional or physical abuse inflicted by a spouse, ex-spouse, a present or former boy- or girlfriend, or date. For the purposes of this paper, we consider DV interchangeable with intimate partner violence. There has been a national concern that abusive events are under-reported. The National Crime Victimization Survey, an anonymous household survey, indicated nearly 1 million incidents of non-lethal intimate partner violence per year between 1992 and 1996. The number decreased from 1.1 million in 1993 to 840,000 in 1996. Attempts to validate such data for a given geographic area often require subjects to violate anonymity--this may account for lower

  10. Height System Unification in North America

    Sideris, Michael; Amjadiparvar, Babak

    2015-04-01

    GOCE has contributed important gravity information towards the definition and realization of the new North American height reference system. In addition to the new gravimetric geoid models based on GOCE, offsets of the classical levelling-based vertical datums in North America, namely CGVD28 in Canada and NAVD88 in the USA and Mexico, can be computed with respect to a global equipotential surface defined by means of a GOCE-based geoid. Although the two datums will eventually be replaced by a common and continent-wide vertical datum (and in fact the new Canadian height datum established in 2013 is already geoid based), their connection and unification is of great interest to the scientific and user communities. This study investigates the practical implementation of the geodetic boundary value problem (GBVP) approach as a rigorous method for unifying classical levelling-based vertical datums. The so-called indirect bias term, the effect of the GOCE geoid omission error, the effect of the systematic levelling datum errors and distortions, and the effect of the data errors on the datum unification are of great importance for the practical implementation of this approach. These factors are investigated numerically using the GNSS-levelling and tide gauge (TG) stations in Canada, the USA, Alaska, and Mexico. The results show that the indirect bias term can be omitted if a GOCE-based global geopotential model is used in geoid computation. This is significant because the omission of the indirect bias term simplifies the geoid computations as well as the linear system of equations for the estimation of datum offsets. Because of the existing systematic levelling errors and distortions in the Canadian and US levelling networks, the datum offsets are investigated in eight smaller regions along Canadian and US coastal areas instead of over the whole North American land mass. The effect of the omission error on the datum offsets decreases significantly in areas with good

  12. Browning boreal forests of western North America

    Verbyla, David

    2011-12-01

    The GIMMS NDVI dataset has been widely used to document a 'browning trend' in North American boreal forests (Goetz et al 2005, Bunn et al 2007, Beck and Goetz 2011). However, there has been speculation (Alcaraz-Segura et al 2010) that this trend may be an artifact due to processing algorithms rather than an actual decline in vegetation activity. This conclusion was based primarily on the fact that GIMMS NDVI did not capture NDVI recovery within most burned areas in boreal Canada, while another dataset consistently showed post-fire increasing NDVI. I believe that the results of Alcaraz-Segura et al (2010) were due simply to different pixel sizes of the two datasets (64 km2 versus 1 km2 pixels). Similar results have been obtained from tundra areas greening in Alaska, with the results simply due to these pixel size differences (Stow et al 2007). Furthermore, recent studies have documented boreal browning trends based on NDVI from other sensors. Beck and Goetz (2011) have shown the boreal browning trend derived from a different sensor (MODIS) to be very similar to the boreal browning trend derived from the GIMMS NDVI dataset for the circumpolar boreal region. Parent and Verbyla (2010) found similar declining NDVI patterns based on NDVI from Landsat sensors and GIMMS NDVI in boreal Alaska. Zhang et al (2008) found a similar 'browning trend' in boreal North America based on a production efficiency model using an integrated AVHRR and MODIS dataset. The declining NDVI trend in areas of boreal North America is consistent with tree-ring studies (D'Arrigo et al 2004, McGuire et al 2010, Beck et al 2011). The decline in tree growth may be due to temperature-induced drought stress (Barber et al 2000) caused by higher evaporative demands in a warming climate (Lloyd and Fastie 2002). In a circumpolar boreal study, Lloyd and Bunn (2007) found that a negative relationship between temperature and tree-ring growth occurred more frequently in warmer parts of species' ranges

  13. North Korea has the means to develop a nuclear weapon

    For a long time already, North Korea has been developing technology that could be used to produce a nuclear weapon. Progress of the nuclear weapons programme has been monitored by means of satellites, and proof of the programme has been obtained, for instance, from a diplomat who defected and when unauthorized exports have been revealed. Led by the United States, the international community has wanted to bring the nuclear weapons programme to an end, but the exceptional negotiating skills of North Korean representatives and sudden turns of events have made the task the difficult one. North Korea has been threatened with economic sanctions, and the International Atomic Energy Agency has decided to cease all technical assistance to North Korea. North Korea could hardly benefit from the use of a nuclear weapon: instead, giving up the programme might help the country economically. The death of the country's dictatorial leader Kim Il Sung seems to have increased the willingness to give up the programme. However, not the slightest information has yet been received as to the destiny of the plutonium already produced. In the end, North Korea may not be required to cancel the entire nuclear weapons programme; freezing the programme may be enough. Thus there would eventually be silent approval of the North Korean nuclear weapons programme. (orig.)

  14. Analysis of North Korea's Nuclear Tests under Prospect Theory

    North Korea has chosen nuclear weapons as the means to protect its sovereignty. Despite international society's endeavors and sanctions to encourage North Korea to abandon its nuclear ambition, North Korea has repeatedly conducted nuclear testing. In this paper, the reason for North Korea's addiction to a nuclear arsenal is addressed within the framework of cognitive psychology. The prospect theory addresses an epistemological approach usually overlooked in rational choice theories. It provides useful implications why North Korea, being under a crisis situation has thrown out a stable choice but taken on a risky one such as nuclear testing. Under the viewpoint of prospect theory, nuclear tests by North Korea can be understood as follows: The first nuclear test in 2006 is seen as a trial to escape from loss areas such as financial sanctions and regime threats; the second test in 2009 was interpreted as a consequence of the strategy to recover losses by making a direct confrontation against the United States; and the third test in 2013 was understood as an attempt to strengthen internal solidarity after Kim Jong-eun inherited the dynasty, as well as to enhance bargaining power against the United States. Thus, it can be summarized that Pyongyang repeated its nuclear tests to escape from a negative domain and to settle into a positive one. In addition, in the future, North Korea may not be willing to readily give up its nuclear capabilities to ensure the survival of its own regime

  15. Have Titan's North-Polar Lakes Changed?

    Wall, Stephen D.; Hayes, A.; Elachi, C.; Stofan, E.; Paillou, P.; Formico, T.; Mitchell, K.; Casarano, D.; Notarnicola, C.

    2012-10-01

    Cassini's RADAR instrument acquired a SAR swath over Titan's north polar lakes on May 22, 2012 , providing repeat images of a number of the smaller lakes. Previous coverage of these lakes was obtained on various passes in 2006 and 2007. Among the principal objectives of the Cassini mission is to monitor the liquid in the lakes with the approach of northern summer. Evidence of change in the lakes' levels might consist of shoreline changes, changes in radar backscatter (e.g. as penetration increases or dry spots appear), or combinations of these. We have chosen ten lakes and lake complexes for study, ranging from -4 to -100 km largest dimension. Visual comparison of repeat images is complicated by the dissimilar imaging geometry and (in some cases) resolution, and by SAR speckle. There are ambiguous cases that require further study, but at this writing we cannot identify certain changes. Ambiguous cases will be analyzed by using electromagnetic models, which can also take into account different acquisition geometry. Further analysis will be carried out exploiting electromagnetic scattering models and inversion approaches (e.g., Bayesian) to provide estimate of the lake parameters and any related changes. Parts of the research described in this paper were carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

    1997-12-01

    Full Text Available Favism is an acute hemolytic anemia which occurs in people who have (G6PD deficiency. In Iran G6PD deficiency is prevalent in the coast of Caspian Sea. The main aim of our study was to investigate the prevalence of Favism in Mazandaran province in north of Iran. Our main source of data was the tiles of patients’ who had been hospitalized in three different children’s hospital in different cities (Babolsar and Gorgan. Results showed that favism occurs in may which is the harvest time of broad beans in Mazandaran province. In Gorgan , favism occurs one week earlier than Babolsar. The ratio of male to female patients in the province was 2~:t, The majority of the patients were villagers. Approximately 70% of the patients were below 5 years old. The signs and symptoms would appear in the patients 1-3 day after eating broad beans. No significant relation was observed between blood groups and G6PD deficiency. No death was reported in the three cities.

  17. Contact, Incorporation, and the North American Southeast

    Shirley A. Hollis

    2015-08-01

    Full Text Available The broadening of the world-system, which involves the geographic expansion into previously external areas and integration of new economies into its network of economic relationships, is represented in world-system scholarship by two competing views. On the one hand, Wallerstein and his associates treat incorporation as being specifically contingent on the routine and systematic economic exchange for durable goods produced in the previously external area to the benefit of the core. In contrast, Hall and Chase-Dunn contend that incorporation is a synchronous process that takes different forms depending onthe relative locations within the hierarchical world-economy of both the previously external areas and the “incorporating” area. Using the sixteenth-century North American Southeast as an episode of incorporation, this study examines the contact relationship between early European explorers and the indigenous groups in the formerly external area. My goal is to illuminate more fully how contact may permanently alter the social organization and relations within the region and, consequently, the form taken by subsequent integration into the world-system.

  18. Emigrated neuroscientists from Berlin to North America.

    Holdorff, Bernd

    2016-01-01

    The highest number of German scholars and physicians, forced by the National Socialist regime to emigrate for "race" or political reasons, were from Berlin. Language and medical exams were requested differently in their new host country-the United States-leading to a concentration of immigrants in the New York and Boston areas. Very early Emergency Committees in Aid of German Scholars and Physicians were established. Undergraduate students (like F. A. Freyhan, H. Lehmann, and H.-L. Teuber) from Berlin seemed to integrate easily, in contrast to colleagues of more advanced age. Some of the former chiefs and senior assistants of Berlin's neurological departments could achieve a successful resettlement (C. E. Benda, E. Haase, C. F. List, and F. Quadfasel) and some a minor degree of success (F. H. Lewy and K. Goldstein). A group of neuropsychiatrists from Bonhoeffer's staff at the Berlin Charité Hospital could rely on the forceful intercession of their former chief. The impact of the émigré colleagues on North American neuroscience is traced in some cases. Apart from the influential field of psychoanalysis, a more diffuse infiltration of German and European neuropsychiatry may be assumed. The contribution to the postwar blossoming of neuropsychology by the émigré neuroscientists K. Goldstein, F. Quadfasel, and H.-L. Teuber is demonstrated in this article. PMID:26853762

  19. Species longevity in North American fossil mammals.

    Prothero, Donald R

    2014-08-01

    Species longevity in the fossil record is related to many paleoecological variables and is important to macroevolutionary studies, yet there are very few reliable data on average species durations in Cenozoic fossil mammals. Many of the online databases (such as the Paleobiology Database) use only genera of North American Cenozoic mammals and there are severe problems because key groups (e.g. camels, oreodonts, pronghorns and proboscideans) have no reliable updated taxonomy, with many invalid genera and species and/or many undescribed genera and species. Most of the published datasets yield species duration estimates of approximately 2.3-4.3 Myr for larger mammals, with small mammals tending to have shorter species durations. My own compilation of all the valid species durations in families with updated taxonomy (39 families, containing 431 genera and 998 species, averaging 2.3 species per genus) yields a mean duration of 3.21 Myr for larger mammals. This breaks down to 4.10-4.39 Myr for artiodactyls, 3.14-3.31 Myr for perissodactyls and 2.63-2.95 Myr for carnivorous mammals (carnivorans plus creodonts). These averages are based on a much larger, more robust dataset than most previous estimates, so they should be more reliable for any studies that need species longevity to be accurately estimated.

    Gerdts, G.; Brandt, P.; Kreisel, K.; Boersma, M.; Schoo, K. L.; Wichels, A.

    2013-12-01

    Copepods can be associated with different kinds and different numbers of bacteria. This was already shown in the past with culture-dependent microbial methods or microscopy and more recently by using molecular tools. In our present study, we investigated the bacterial community of four frequently occurring copepod species, Acartia sp., Temora longicornis, Centropages sp. and Calanus helgolandicus from Helgoland Roads (North Sea) over a period of 2 years using DGGE (denaturing gradient gel electrophoresis) and subsequent sequencing of 16S-rDNA fragments. To complement the PCR-DGGE analyses, clone libraries of copepod samples from June 2007 to 208 were generated. Based on the DGGE banding patterns of the two years survey, we found no significant differences between the communities of distinct copepod species, nor did we find any seasonality. Overall, we identified 67 phylotypes (>97 % similarity) falling into the bacterial phyla of Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria. The most abundant phylotypes were affiliated to the Alphaproteobacteria. In comparison with PCR-DGGE and clone libraries, phylotypes of the Gammaproteobacteria dominated the clone libraries, whereas Alphaproteobacteria were most abundant in the PCR-DGGE analyses.

  2. North Central Project: Environment act proposal

    Manitoba Hydro proposes to construct a power transmission and distribution line system to connect 12 northern Manitoba communities to the utility's central power grid. The purpose of this North Central Project (NCP) is to provide reliable and unrestricted electric service to remote communities now largely receiving limited diesel-generated power. The NCP is composed of a 138-kV transmission line running ca 350 km from the Kelsey Generating Station, ca 160 km of 25-kV distribution lines, new transformer stations at four communities, upgraded internal distribution systems within the communities, removal of existing diesel stations and restoration of the sites, modifications and additions to the Kelsey switchyard, and a communications system. The NCP is described in detail, including proposed line routes and transformer station locations, rationales for site and route selection, projected impacts on the environment and local societies, and consultations with the communities to be affected. Potential impacts are expected to be modest, with few unmitigable adverse impacts and a number of potentially significant positive benefits. Impact management measures are proposed to prevent or mitigate adverse effects and to create or enhance positive impacts such as local employment of native peoples. 49 figs., 1 tab

  3. Environmental management in North American mining sector.

    Asif, Zunaira; Chen, Zhi

    2016-01-01

    This paper reviews the environmental issues and management practices in the mining sector in the North America. The sustainable measures on waste management are recognized as one of the most serious environmental concerns in the mining industry. For mining activities, it will be no surprise that the metal recovery reagents and acid effluents are a threat to the ecosystem as well as hazards to human health. In addition, poor air quality and ventilation in underground mines can lead to occupational illness and death of workers. Electricity usage and fuel consumption are major factors that contribute to greenhouse gases. On the other hand, many sustainability challenges are faced in the management of tailings and disposal of waste rock. This paper aims to highlight the problems that arise due to poor air quality and acid mine drainage. The paper also addresses some of the advantages and limitations of tailing and waste rock management that still have to be studied in context of the mining sector. This paper suggests that implementation of suitable environmental management tools like life cycle assessment (LCA), cleaner production technologies (CPTs), and multicriteria decision analysis (MCD) are important as it ultimately lead to improve environmental performance and enabling a mine to focus on the next stage of sustainability.

    Full Text Available The study reviews causes of urolithiasis and its manifestations in North-West (NW Libya. Libyan childhood urolithiasis accounted for 3.6% of nephrology out-patient work load. There were 59 children with urolithiasis, including 34 boys and 25 girls with a mean age of 2.8 ± 2.42 years. Urolithiasis was more common among younger age groups (P = 0.001 and in boys with primary oxaluria and infective etiology. The causes of urolithiasis included metabolic stones in 64%, infective in 26%, and it was idiopathic in 10%. Overall, family history of renal stone disease was elicited in 59%; it was 92% in patients with primary oxaluria. The main presenting features were abdominal pain (27%, gross hematuria (22%, associated urinary tract infection (UTI; 24%, and stone release in 19%. Stone location was bilateral in 64%, multiple in 68%, and in the upper tract in 93% (P = 0.05. Important complications encountered included chronic renal failure (13%, hydronephrosis (34%, systemic hypertension (8%, and rickets in 17%. Calcium oxalate was the most prominent constituent, seen in 41% of the calculi, followed by struvite (21%, uric acid (10%, carbapatite (7%, and cystine (3.5%. Diagnostically helpful findings were family history, age at presentation, UTI by urease producing organisms, rickets, imaging and chemical analysis of calculi. Early detection and prompt treatment helps in preventing long-term sequelae in patients with urolithiasis.

  5. Deglacial hydroclimate of midcontinental North America

    During the last deglaciation temperatures over midcontinental North America warmed dramatically through the Bølling-Allerød, underwent a cool period associated with the Younger-Dryas and then reverted to warmer, near modern temperatures during the early Holocene. However, paleo proxy records of the hydroclimate of this period have presented divergent evidence. We reconstruct summer relative humidity (RH) across the last deglacial period using a mechanistic model of cellulose and leaf water δ18O and δD combined with a pollen-based temperature proxy to interpret stable isotopes of sub-fossil wood. Midcontinental RH was similar to modern conditions during the Last Glacial Maximum, progressively increased during the Bølling-Allerød, peaked during the Younger-Dryas, and declined sharply during the early Holocene. This RH record suggests deglacial summers were cooler and characterized by greater advection of moisture-laden air-masses from the Gulf of Mexico and subsequent entrainment over the mid-continent by a high-pressure system over the Laurentide ice sheet. These patterns help explain the formation of dark-colored cumulic horizons in many Great Plains paleosol sequences and the development of no-analog vegetation types common to the Midwest during the last deglacial period. Likewise, reduced early Holocene RH and precipitation correspond with a diminished glacial high-pressure system during the latter stages of ice-sheet collapse.

  6. North Korea's nuclear power programme revealed

    The extent of the nuclear programme in the Democratic People's Republic of Korea (DPRK) was revealed in May 1992: reports on the country's facilities were handed to the International Atomic Energy Agency and an Agency group visited Korea on a ''familiarisation visit''. DPRK's nuclear programme had been the subject of speculation for some time. While the country had signed the Non-Proliferation Treaty and two facilities were already under IAEA safeguards - a research reactor and a critical facility, both at the Institute of Nuclear Physics - there were a number of indicators that DPRK was pursuing a nuclear programme aimed at military use. The new openness was prompted by a number of factors including discussions on closer relations with South Korea. DPRK signed a comprehensive Safeguards Agreement on 30 January 1992. On the familiarisation visit by the IAEA director general in May the DPRK revealed nuclear facilities in operation or under construction at five sites. At Pakchon and Pyongsan: each site housed a uranium mine and uranium-ore concentration plant. At Pyongyang: the two facilities already under safeguards at the Institute of Nuclear Physics; and a sub critical facility at Kim Il Sung university. At Nyongbyon: a fuel fabrication plant; an 5MWe experimental power reactor, in operation; a 50MWe prototype power reactor under construction; and a facility ultimately intended as a reprocessing plant, but described by North Korea, because of its unfinished state, as a laboratory. At Taechon: a 200MWe power reactor under construction. (author)

  7. Bringing Home the Japanese Abductees from North Korea

    ITO, Takuya

    2007-11-01

    Full Text Available This paper discusses the official and unofficial attitude of former Japanese prime minister Abe Shinzo towards the abductions of Japanese people by North Korea. Officially, Abe displayed an aggressive attitude towards the problem. However, unofficially, he possessed an ingratiating attitude. A Japanese weekly magazine reported that he had been in regular negotiations with North Korea surreptitiously. Abe's ingratiating attitude may be explained by his alleged connection with the Holy Spirit Association for the Unification of World Christianity—which preaches the establishment of a harmonious relationship with North Korea. Abe's dual attitude confounded the families of the abductees as they were unable to ascertain which of his attitudes was genuine.

    2015-02-01

    Full Text Available The last decades of the twentieth century have been a time of new visibility and social activism for Buddhists in Taiwan and around the world. This paper compares the social engagement of nuns in the Chinese Buddhist tradition in Taiwan and North America. I would like to argue that whereas nuns in Taiwan have developed a variety of approaches to social involvement, their counterparts in the Chinese diaspora in North America have had to face a set of challenges specific to overseas Chinese communities in addition to Chinese Buddhist tradition. The article concludes with reflections on the prospects for nuns' social activism in Taiwan and North America in future years.

    Chaodong Zhao

    2003-12-01

    Full Text Available These are few sites about 10 000 BP in the early Neolithic period in North China; among these, the Donghulin site is the only one which included the remains of peoples' use of fire (hearth pits, stone implements, pottery objects, and human tombs. The excavation of the Donghulin site in 2001 provides very important information for research on people and culture in the early Neolithic period in North China. The finding of Donghulin Man has filled the gap in our knowledge of human development since the period of the "Upper Cave Man" (30 000a BP in North China. It is also important for research on people-land relationships.

  11. More North Sea oil flowing despite stormy disruptions

    North Sea operations this year have been plagued by storms, a perennial problem off Northwest Europe. Even so, operators continued to log progress in placing new fields on stream. Seventeen U.K. offshore fields have gone on stream during 1993, compared with Norway's four, Netherlands' three, and Denmark's two. Although the boom days are over for the North Sea, some operators are convinced that reduction of development and operational costs could yield opportunities in the region for years to come. The paper discusses selected highlights of the year's operations in the North Sea

  14. North American Water Program (NAWP): A Vision to Address North America's Freshwater Sustainability Challenges

    Belvedere, D. R.; Houser, P. R.; Schiffer, R. A.; Entin, J. K.

    2013-12-01

    Dramatically changing climates has had an indelible impact on North America's water crisis; the rapid melting of glaciers has profound implications for the sustainability of Canada's rivers. However, projective increases in water demand from increasing population, industrial energy, and agriculture needs may have four times more impact on the water supply-demand imbalance than climate change. Reliable prediction of hydrologic change and extremes is of critical importance for policy and decision makers to adapt to these future water challenges. However, the models that we use to understand and forecast water availability, flooding, and drought are simply not up to the task of addressing our most pressing societal issues and national security. We need a decisive and coordinative effort to systematically improve water cycle prediction skill, coupled with reliable methodologies to translate those predictions into actionable water supply and quality information to support sustainable water management - this is a primary motivation for the proposed North American Water Program (NAWP). To decisively address these challenges, we recommend that NAWP coalesce an interdisciplinary, international and interagency effort to make significant contributions to continental-to-decision-scale hydroclimate science and solutions. By entraining, integrating and coordinating the vast array of interdisciplinary observationable and prediction resources available, NAWP will significantly advance skill in predicting, assessing, and managing variability and changes in North American water resources, as an integral part of the global climate system. We adopt three challenges to organize NAWP efforts. The first deals with developing a scientific basis and tools for mitigating and adapting to changes in the water supply-demand balance. The second challenge is benchmarking; to use incomplete and uncertain observations to assess water storage and quality dynamics, and to characterize the

  15. Hydrography and through-flow in the north-eastern North Atlantic Ocean: the NANSEN project

    van Aken, H. M.; Becker, G.

    The circulation and hydrography of the north-eastern North Atlantic has been studied with an emphasis on the upper layers and the deep water types which take part in the thermohaline overturning of the Oceanic Conveyor Belt. Over 900 hydrographic stations were used for this study, mainly from the 1987-1991 period. The hydrographic properties of Subpolar Mode Water in the upper layer, which is transported towards the Norwegian Sea, showed large regional variation. The deep water mass was dominated by the cold inflow of deep water from the Norwegian Sea and by a cyclonic recirculation of Lower Deep Water with a high Antarctic Bottom Water content. At intermediate levels the dominating water type was Labrador Sea Water with only minor influence of Mediterranean Sea Water. In the permanent pycnocline traces of Antarctic Intermediate Water were found. Geostrophic transports have been estimated, and these agreed in order of magnitude with the local heat budget, with current measurements, with data from surface drifters, and with the observed water mass modification. A total of 23 Sv of surface water entered the region, of which 20 Sv originated from the North Atlantic Current, while 3 Sv entered via an eastern boundary current. Of this total, 13 Sv of surface water left the area across the Reykjanes Ridge, and 7 Sv entered the Norwegian Sea, while 3 Sv was entrained by the cold overflow across the Iceland-Scotland Ridge. Approximately 1.4 Sv of Norwegian Sea Deep Water was involved in the overflow into the Iceland Basin, which, with about 1.1 Sv of entrained water and 1.1 Sv recirculating Lower Deep Water, formed a deep northern boundary current in the Iceland Basin. At intermediate depths, where Labrador Sea Water formed the dominant water type, about 2 Sv of entrained surface water contributed to a saline water mass which was transported westwards along the south Icelandic slope.

  16. Effects of tropical North Atlantic SST on tropical cyclone genesis in the western North Pacific

    Yu, Jinhua; Li, Tim; Tan, Zhemin; Zhu, Zhiwei

    2016-02-01

    The tropical cyclone genesis number (TCGN) in July-October (JASO) over the western North Pacific (WNP) exhibits a robust interannual variation. It shows a longitudinally tri-pole pattern with a high in the eastern WNP and South China Sea (SCS) and a low in the western WNP, which explain 42.2 and 23.4 % of total TCGN variance in the eastern WNP and SCS, respectively. The high-low-high pattern is similar to that derived from a TC genesis potential index (GPI). To understand the cause of the longitudinal distribution of the dominant interannual mode, we examine the contributions of environmental parameters associated with GPI. It is found that relative humidity and relative vorticity are important factors responsible for TC variability in the SCS, while vertical shear and relative vorticity are crucial in determining TC activity in eastern WNP. A simultaneous correlation analysis shows that the WNP TCGN in JASO is significantly negatively correlated (with a correlation coefficient of -0.5) with sea surface temperature anomalies (SSTA) in the tropical North Atlantic (TNA). The longitudinal distribution of TC genesis frequency regressed onto TNA SSTA resembles that regressed upon the WNP TCGN series. The spatial patterns of regressed environmental variables onto the SSTA over the TNA also resemble those onto TCGN in the WNP, that is, an increase of relative humidity in the SCS and a weakening of vertical shear in the eastern WNP are all associated with cold SSTA in the TNA. Further analyses show that the cold SSTA in the TNA induce a negative heating in situ. In response to this negative heating, a low (upper)-level anomalous aniti-cyclonic (cyclonic) flows appear over the subtropical North Atlantic and eastern North Pacific, and to east of the cold SSTA, anomalous low-level westerlies appear in the tropical Indian Ocean. Given pronounced mean westerlies in northern Indian Ocean in boreal summer, the anomalous westerly flows increase local surface wind speed and surface

  17. Space Radar Image of North Sea, Germany

    1994-01-01

    This is an X-band image of an oil slick experiment conducted in the North Sea, Germany. The image is centered at 54.58 degrees north latitude and 7.48 degrees east longitude. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on October 6, 1994, during the second flight of the spaceborne radar. The experiment was designed to differentiate between petroleum oil spills and natural slicks floating on the sea surface. Two types of petroleum oil and six types of oils resembling natural sea surface slicks were poured on the sea surface from ships and a helicopter just before the space shuttle flew over the region. At the bottom of the image is the Sylt peninsula, a famous holiday resort. Twenty-six gallons (100 liters) of diesel oil was dissipated due to wave action before the shuttle reached the site. The oil spill seen at the uppermost part of the image is about 105 gallons (400 liters) of heavy heating oil and the largest spill is about 58 gallons (220 liters) of oleyl alcohol, resembling a 'natural oil' like the remaining five spills used to imitate natural slicks that have occurred offshore from various states. The volume of these other oils spilled on the ocean surface during the five experimental spills varied from 16 gallons to 21 gallons (60 liters to 80 liters). The distance between neighboring spills was about half a mile (800 meters) at the most. The largest slick later thinned out to monomolecular sheets of about 10 microns, which is the dimension of a molecule. Oceanographers found that SIR-C/X-SAR was able to clearly distinguish the oil slicks from algae products dumped nearby. Preliminary indications are that various types of slicks may be distinguished, especially when other radar wavelengths are included in the analysis. Radar imaging of the world's oceans on a continuing basis may allow oceanographers in the future to detect and clean up oil spills much more

  18. Lifestyle survey amongst North Sea oil workers

    Recognition is growing of the influence of the workplace on lifestyle, and its consequent effect on health. This relation between work, lifestyle and health is highly relevant to the North Sea oil and gas industry where employment often demands the adoption of, and exposure to, a lifestyle far removed from that of comparable onshore occupations. This risk factors for Coronary Heart Disease (CHD) which is the largest single cause of premature adult death in Great Britain can be classified according to those that are immodifiable (eg gender), and those that result from lifestyle choices (eg smoking, diet). The demographic profile (predominant gender, age group and nationality) of the offshore workforce is thought to place it in an inherently high risk group for CHD. Anecdotal evidence further suggests that the offshore lifestyle may expose the workforce to increased CHD risk factors, particularly in terms of diet, tobacco consumption and exercise habits. The lifestyle of offshore workers may be considered as a form of occupational hazard, comparable with recognised occupational risks. A sample of 500 offshore workers undertaking survival training were surveyed using a structured questionnaire to investigate aspects of their lifestyle. Subjects compared their smoking, dietary and exercise habits between periods onshore and offshore. Analysis of results pointed to some significant differences in lifestyle between these two periods. Additional factors such as occupation status (whether directly employed or contracted), onshore alcohol consumption, and subjects` perception of job and family satisfaction were also analysed in relation to lifestyle. Results indicate the potential benefits of health promotion intervention. Opportunities for such intervention are identified and discussed within the context of caring for an efficient utilisation of the Offshore Industry`s human resources. (Author)

  19. The 'individualization' of large North American mammals.

    Ruth, J L; Fain, S R

    1993-01-01

    The enforcement of wildlife laws and the captive breeding of threatened/endangered species requires the ability to identify individual animals. DNA profiles of a variety of large North American mammals, birds, and fish were generated using ten different oligonucleotide probes. The probes tested were four multilocus probes [33.6, 33.15, JE46, and (TGTC)5] and six 'human unilocus' probes [MS1 (D1S7), CMM101 (D14S13), YNH24 (D2S44), EFD52 (D17S26), TBQ7 (D10S28), and MS43 (D12S11). Each of the probes was chemically synthesized, and labeled by the attachment of alkaline phosphatase; after hybridization, the probes were detected by chemiluminescence catalyzed by the enzyme. Initial screening against zoo blots including samples of bear, wolf, large cat, wild sheep, deer, birds, marine mammals, and fish indicated that three multilocus probes [33.15, 33.6, (TGTC)5] gave informative patterns containing 15-40 bands for most or all of the animals tested, as did two of the 'human unilocus' probes (MS1 and CMM101). The other five probes appeared informative only in some species (for example, YNH24 against canids). Subsequent screenings of populations within species were used to determine genetic diversity by analysis of observed bandsharing (S). Large heterologous populations, such as white-tailed deer, exhibited highly diverse band patterns (S Mexican wolves, Tule elk, and Columbian white-tailed deer, exhibited much higher frequencies of bandsharing (0.6 < or = S < or = 0.95).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8400711

  20. Novel fen ecosystems in western North Carolina

    Wilcox, J. D.

    2012-12-01

    Western North Carolina is mountainous, and groundwater flows from hillslope recharge zones to valley stream and spring discharge zones. Depending on surface topography and geologic conditions, the water table may approach or intersect the ground surface to form seepage wetlands, or fens. Fen ecosystems can be very sensitive to changes in land use, groundwater pumping, and upslope development. This presentation will focus on two sites where historical land use and human activity played important roles in creating or preserving fen ecosystems. Both sites now support—and are being managed to protect—federally endangered flora and fauna. The first site is home to Sarracenia oreophilia, an endangered pitcher plant that thrives on saturated soils with low nutrient content. The site's early history includes tree clearing, drain tile installation, and cattle grazing, while more recent management activities have included drain tile excavation, manual invasive removal, and prescribed burns. A 15-year water-level record indicates seasonal artesian conditions wet a 3m clay unit (K=2E-5 cm/sec) beneath the site, which is able to retain moisture during drier periods. Shorter "clay wetting periods" during drought years (1999-2000; 2007-2008) correspond to reduced clump counts in pitcher-plant surveys. The second site is a former aggregate quarry that now supports over 60 bog turtles (Clemmys muhlenbergii). The biggest threat to this site is encroachment of non-native and invasive multiflora rose (Rosa multiflora) and other large woody species. Management activities include manual removal and prescribed goat herbivory. Current efforts to characterize the springs, water-table, and surface-water flows will be used to detect changes in the future to the hydrologic regime in the fen.

  1. North American Wetlands and Mosquito Control

    Gabrielle E. Sakolsky-Hoopes

    2012-12-01

    Full Text Available Wetlands are valuable habitats that provide important social, economic, and ecological services such as flood control, water quality improvement, carbon sequestration, pollutant removal, and primary/secondary production export to terrestrial and aquatic food chains. There is disagreement about the need for mosquito control in wetlands and about the techniques utilized for mosquito abatement and their impacts upon wetlands ecosystems. Mosquito control in wetlands is a complex issue influenced by numerous factors, including many hard to quantify elements such as human perceptions, cultural predispositions, and political climate. In spite of considerable progress during the last decades, habitat protection and environmentally sound habitat management still remain inextricably tied to politics and economics. Furthermore, the connections are often complex, and occur at several levels, ranging from local businesses and politicians, to national governments and multinational institutions. Education is the key to lasting wetlands conservation. Integrated mosquito abatement strategies incorporate many approaches and practicable options, as described herein, and need to be well-defined, effective, and ecologically and economically sound for the wetland type and for the mosquito species of concern. The approach will certainly differ in response to disease outbreaks caused by mosquito-vectored pathogens versus quality of life issues caused by nuisance-biting mosquitoes. In this contribution, we provide an overview of the ecological setting and context for mosquito control in wetlands, present pertinent information on wetlands mosquitoes, review the mosquito abatement options available for current wetlands managers and mosquito control professionals, and outline some necessary considerations when devising mosquito control strategies. Although the emphasis is on North American wetlands, most of the material is applicable to wetlands everywhere.

  9. Wind Powering America: The Next Steps in North Carolina

    Banks, Jennifer L. [North Carolina Solar Center; Scanlin, Dennis [Appalachian State University; Quinlan, Paul [North Carolina Sustainable Energy Association

    2013-06-18

    The goal of this project is to apply the WPA’s proactive outreach strategy to the problem of educating the public about the likely transmission infrastructure developments concomitant to the significant development of wind energy resources in North Carolina. Given the lead time to develop significant new transmission infrastructure (5-10 years), it is critical to begin this outreach work today, so that wind resources can be developed to adequately meet the 20% by 2030 goal in the mid- to long-term (10-20 years). The project team planned to develop a transmission infrastructure outreach campaign for North Carolina by: (1) convening a utility interest group (UIG) of the North Carolina Wind Working Group (NC WWG) consisting of electric utilities in the state and the Southeast; and (2) expanding outreach to local and state government officials in North Carolina.

  15. The North Sea: perspectives on regional environmental co-operation

    The North Sea is important to many countries. Its well-being depends on even more. Representatives of many of these countries meet at the North Sea Conferences to discuss current and future issues on all aspects of the North Sea environment. In this issue a perspective view of the Conferences is taken in the first part (7 papers). This includes the history of the Conference, the legal status of the North Sea declarations and problems of their implantation. Existing frameworks are considered in the second part (11 papers). Outstanding issues on specific problems such as marine life are discussed in the final part (8 papers). This includes an article on radiological discharges, which come mostly from the Sellafield Reprocessing plant, which is indexed separately. (U.K.)

  6. Seasonal forecasting of intense tropical cyclones over the North Atlantic and the western North Pacific basins

    Choi, Woosuk; Ho, Chang-Hoi; Jin, Chun-Sil; Kim, Jinwon; Feng, Song; Park, Doo-Sun R.; Schemm, Jae-Kyung E.

    2016-02-01

    Intense tropical cyclones (TCs) accompanying torrential rain and powerful wind gusts often cause substantial socio-economic losses in the regions around their landfall. This study analyzes intense TCs in the North Atlantic (NA) and the western North Pacific (WNP) basins during the period 1982-2013. Different intensity criteria are used to define intense TCs for these two basins, category 1 and above for NA and category 3 and above for WNP, because the number of TCs in the NA basin is much smaller than that in the WNP basin. Using a fuzzy clustering method, intense TC tracks in the NA and the WNP basins are classified into two and three representative patterns, respectively. On the basis of the clustering results, a track-pattern-based model is then developed for forecasting the seasonal activities of intense TCs in the two basins. Cross-validation of the model skill for 1982-2013 as well as verification of a forecast for the 2014 TC season suggest that our intense TC model is applicable to operational uses.

    Ice discharge from north and northeast Greenland calculated from satellite radar interferometry data of 14 outlet glaciers is 3.5 times that estimated from iceberg production. The satellite estimates, obtained at the grounding line of the outlet glaciers, differ from those obtained at the glacier front, because basal melting is extensive at the underside of the floating glacier sections. The results suggest that the north and northeast parts of the Greenland ice sheet may be thinning and cont...

  4. The importance of North Sea gas to European energy supply

    Natural gas can, of course, be transported over very long distances but, because of the economics of gas transmission, its impact is most often local. This has certainly been the case with North Sea gas, which has clearly contributed significantly to European energy supply and will continue to do so for some time to come. The historical importance of the discovery of gas in the North Sea has been that it has enabled natural gas industries to grow rapidly in North West Europe. Without North Sea gas and Dutch gas it is difficult to see how town gas would have been replaced in North West Europe. Certainly, a much smaller natural gas industry would have emerged. North Sea gas has inevitably had the greatest impact on gas markets in the countries of the European Community and this will remain the case in future. Nevertheless, it is inevitable that gas will, in future, flow across more national boundaries than in the past, and that North Sea gas will have an important part to play in meeting the Central European demand for competitively priced, secure supplies. This paper discusses the United Kingdom market for gas and future demand both in the United Kingdom and more widely in Europe. An examination of the availability of gas supplies from the North Sea suggests that it is unlikely that there will be a surplus of gas for export from the United Kingdom continental shelf. Norway will remain the main source of exports, with the Netherlands also in a strong position. Transportation and political aspects are also considered. (author)

  5. Introduction to the Population Ecology of North American Caribou

    Dale R. Seip

    1996-01-01

    Full Text Available Bergerud has discussed how major differences in caribou density across North America appear to be related to the impact of wolf (Canis lupus predation, and the strategies used by caribou to avoid wolves. Caribou living in areas without wolves usually occur at high densities and are regulated by competition for food. In this session, we asked the presenters to discuss the population ecology of different caribou herds in North America and to evaluate if they fit the general model.

There are some grounds that should be preceded for Kaesong industrial complex in North Korea to get the political safety and economic prosperity as follow; First, South Korea should improve a sy...

  14. On multidecadal and quasi-decadal North Atlantic variability

    Alvarez-Garcia, F.; Latif, Mojib; Biastoch, Arne

    2008-01-01

    Observed sea surface temperatures (SSTs) in the North Atlantic from 1958 through 2000, as well as data from an ocean model simulation driven with the atmospheric variability observed during the same period, are examined using multichannel singular spectrum analysis. The two leading oscillatory modes are associated with a multidecadal and a quasi-decadal period. The former is connected to a basinwide uniform SST pattern and changes in the deep North Atlantic meridional overturning circulation....

  15. Water Security Problem in North China: Research and Perspective

    XIA Jun; LIU Meng-Yu; JIA Shao-Feng

    2005-01-01

    This paper addresses the emergence of water security problems in North China with the aim of highlighting key water resources management and water security issues for the long-term development of North China. Three key problems related to water resources and security issues in North China in the 21st century are addressed, namely 1) the water cycle under environmental change, 2) agricultural water saving, and 3) water security. Development of international research related to these issues is also reviewed. The research plan developed recently by the Chinese Academy of Sciences (CAS) is discussed and suggestions on research and development of water resources science in North China are presented.Thanks to focus on experimental catchments and dedicated research stations, a detailed knowledge of the water cycle on North China farmland has been compiled. A range of techniques that include isotope tracers has been used to acquire hydrologic data. Much research has been devoted to developing distributed hydrological models at different scales. In the well irrigation district, five different water saving irrigation regimes have been investigated, and these regimes have had widespread application, and reduced water use 60-150 mm while they increased water use efficiency (WUE) by 20%-30%.Furthermore, preventing water pollution is the most essential step to ensure North China's water security.

  16. Reorganization of the North Atlantic Oscillation during early Holocene deglaciation

    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.

  17. Impact of the Interdecadal Pacific Oscillation on Tropical Cyclone Activity in the North Atlantic and Eastern North Pacific

    Wenhong Li; Laifang Li; Yi Deng

    2015-01-01

    Tropical cyclones (TCs) are among the most devastating weather systems affecting the United States and Central America (USCA). Here we show that the Interdecadal Pacific Oscillation (IPO) strongly modulates TC activity over the North Atlantic (NA) and eastern North Pacific (eNP). During positive IPO phases, less (more) TCs were observed over NA (eNP), likely due to the presence of stronger (weaker) vertical wind shear and the resulting changes in genesis potential. Furthermore, TCs over NA te...

  18. The changing cross-border trade dynamics between north-western Uganda, north-eastern Congo and southern Sudan

    Titeca, Kristof

    2009-01-01

    New field work conducted by Kristof Titeca for the CSRC in the border areas of North-Western Uganda, North-Eastern Congo and Southern Sudan yields important lessons about the development of cross-border trading patterns in this region. Informal trade between these countries pre-dates the colonial period, though major political and economic changes have occurred since the 1980's. Drawing from interviews with active traders and government officials, the author argues that internal and external ...

  19. Extreme winds in the Western North Pacific

    Ott, S.

    2006-11-15

    A statistical model for extreme winds in the western North Pacific is developed, the region on the Planet where tropical cyclones are most common. The model is based on best track data derived mostly from satellite images of tropical cyclones. The methods used to estimate surface wind speeds from satellite images is discussed with emphasis on the empirical basis, which, unfortunately, is not very strong. This is stressed by the fact that Japanese and US agencies arrive at markedly different estimates. On the other hand, best track data records cover a long period of time and if not perfect they are at least coherent over time in their imperfections. Applying the the Holland model to the best track data, wind profiles can be assigned along the tracks. From this annual wind speed maxima at any particular point in the region can be derived. The annual maxima, in turn, are fitted to a Gumbel distribution using a generalization Abild's method that allows for data wind collected from multiple positions. The choice of this method is justified by a Monte Carlo simulation comparing it to two other methods. The principle output is a map showing fifty year winds in the region. The method is tested against observed winds from Philippine synoptic stations and fair agreement is found for observed and predicted 48 year maxima. However, the almost biasfree performance of the model could be fortuitous, since precise definitions of 'windspeed' in terms averaging time, height above ground and assumed surface roughness are not available, neither for best tracks nor for the synoptic data. The work has been carried out under Danish Research Agency grant 2104-04-0005 'Offshore wind power' and it also covers the findings and analysis carried out in connection with task 1.6 of the project 'Feasibility Assessment and Capacity Building for Wind Energy Development in Cambodia, The Philippines and Vietnam' during 2005-06 under contract 125-2004 with EU

  20. Lithosphere mapping beneath the North American plate

    2004-09-01

    Major- and trace-element analyses of garnets from heavy-mineral concentrates have been used to derive the compositional and thermal structure of the subcontinental lithospheric mantle (SCLM) beneath 16 areas within the core of the ancient Laurentian continent and 11 areas in the craton margin and fringing mobile belts. Results are presented as stratigraphic sections showing variations in the relative proportions of different rock types and metasomatic styles, and the mean Fo content of olivine, with depth. Detailed comparisons with data from mantle xenoliths demonstrate the reliability of the sections. In the Slave Province, the SCLM in most areas shows a two-layer structure with a boundary at 140-160 km depth. The upper layer shows pronounced lateral variations, whereas the lower layer, after accounting for different degrees of melt-related metasomatism, shows marked uniformity. The lower layer is interpreted as a subcreted plume head, added at ca. 3.2 Ga; this boundary between the layers rises to <100 km depth toward the northern and southern edges of the craton. Strongly layered SCLM suggests that plume subcretion may also have played a role in the construction of the lithosphere beneath Michigan and Saskatchewan. Outside the Slave Province, most North American Archon SCLM sections are less depleted than similar sections in southern Africa and Siberia; this may reflect extensive metasomatic modification. In E. Canada, the degree of modification increases toward the craton margin, and the SCLM beneath the Kapuskasing Structural Zone is typical of that beneath Proterozoic to Phanerozoic mobile belts. SCLM sections from several Proterozoic areas around the margin of the Laurentian continental core (W. Greenland, Colorado-Wyoming district, Arkansas) show discontinuities and gaps that are interpreted as the effects of lithosphere stacking during collisional orogeny. Some areas affected by Proterozoic orogenesis (Wyoming Craton, Alberta, W. Greenland) appear to retain

  1. Understanding the North American natural gas market

    Canada's energy future is largely dependent on natural gas: (1) natural gas meets more than 25 per cent of the country's primary energy demand, (2) it represents the most environmentally friendly fossil fuel, (3) it is the fastest growing fuel of choice for electricity generation and distributed energy initiatives, (4) the development of Canadian Tar Sands depend on natural gas fuels, and (5) it is a key element in efforts to lower emissions of motor vehicles. This paper was prepared to assist the reader in understanding the dynamics forming the basis of the natural gas markets in Canada. Enormous stresses affect Canada's energy systems, such as meeting demands for affordable, reliable energy, and meeting stringent standards of environmental performance. The Canadian Gas Association, along with industry and governments, is of the opinion that stresses can be mitigated with the right steps. Background information on the key drivers of the natural gas markets in Canada was provided in section one of the paper. It demonstrated that the natural gas industry in Canada is tied to the North American marketplace. The principal sources of demand and sources of supply were examined. A brief overview of the changes that took place in the natural gas industry over the last 20 years was provided in an effort to avoid the mistakes of the past. A specific look at deregulation, free trade and price movements was presented. Section two was devoted to market outlooks and integrated perspectives, describing the composite picture of outlooks for demand and supply to 2020. It is felt that demand growth will fall into the 1.9 per cent range per year. The key implications for business and policy were discussed in Section three. Three major implication groups emerged: economic competitiveness of natural gas dependent industries; environment due to the fuel choices driven by gas market dynamics; and implications for consumers. Policy directions were outlined in Section four. The Canadian

  3. North Slope (Wahluke Slope) expedited response action cleanup plan

    1994-02-01

    The purpose of this action is to mitigate any threat to public health and the environment from hazards on the North Slope and meet the expedited response action (ERA) objective of cleanup to a degree requiring no further action. The ERA may be the final remediation of the 100-I-3 Operable Unit. A No Action record of decision (ROD) may be issued after remediation completion. The US Department of Energy (DOE) currently owns or administers approximately 140 mi{sup 2} (about 90,000 acres) of land north and east of the Columbia River (referred to as the North Slope) that is part of the Hanford Site. The North Slope, also commonly known as the Wahluke Slope, was not used for plutonium production or support facilities; it was used for military air defense of the Hanford Site and vicinity. The North Slope contained seven antiaircraft gun emplacements and three Nike-Ajax missile positions. These military positions were vacated in 1960--1961 as the defense requirements at Hanford changed. They were demolished in 1974. Prior to government control in 1943, the North Slope was homesteaded. Since the initiation of this ERA in the summer of 1992, DOE signed the modified Hanford Federal Agreement and Consent Order (Tri-Party Agreement) with the Washington Department of Ecology (Ecology) and the US Environmental Protection Agency (EPA), in which a milestone was set to complete remediation activities and a draft closeout report by October 1994. Remediation activities will make the North Slope area available for future non-DOE uses. Thirty-nine sites have undergone limited characterization to determine if significant environmental hazards exist. This plan documents the results of that characterization and evaluates the potential remediation alternatives.

  5. Effects of aerosols on precipitation in north-eastern North America

    R. Mashayekhi

    2013-10-01

    Full Text Available The changes in precipitation over north-eastern North America caused by chemistry – and particularly anthropogenic aerosols – are investigated using the Chemistry version of the Weather Research and Forecasting (WRF/Chem v3.4 model. The simulations were carried out for a five-month period from April to August 2009. The model results show that non-negligible changes in both convective and cloud-resolved (non-convective precipitation are caused by chemistry and/or aerosols over most parts of the domain. The changes can be attributed to both radiative and microphysical interactions with the meteorology. A chemistry-induced change of approximately −15% is found in the five-month mean daily convective precipitation over areas with high convective rain; most of this can be traced to radiative effects. Although, total non-convective rain is less than total convective rain in the domain, chemistry-induced effects on the former are more pronounced than those on the latter. A chemistry-induced increase of about +30% is evident in the five-month mean daily non-convective precipitation over the heavily urbanized parts of the Atlantic coast. The effects of aerosols on cloud microphysics and precipitation were examined for two particle size ranges: 0.039–0.1 μm and 1–2.5 μm. Strongly positive spatial correlation between cloud droplet number and non-convective rain are found for activated (cloud-borne aerosols in both size ranges. Non-activated (interstitial aerosols have a positive correlation with cloud droplet number and non-convective rain when they are small and an inverse correlation for larger particles.

  6. North Korea's nuclear weapons development. Implications for future policy

    This essay assesses North Korea's long-standing quest for nuclear weapons; alternative strategies for inhibiting Pyongyang's weapons development; and the potential implications for regional security and nonproliferation should the Democratic People's Republic of Korea (DPRK) retain and enhance its weapons programs. North Korea's pursuit of a nuclear weapons capability has long provoked heated debate among policy makers and research analysts about the purposes of engagement with the North, reflecting the repeated frustrations in efforts to negotiate Korean denuclearization. These debates reflect widely divergent views of the North Korean regime; its sustainability as an autonomous political, economic, and military system; and the potential consequences of continued nuclear development in this isolated, highly idiosyncratic state. These questions assume additional salience as North Korea approaches a leadership succession for only the second time in its six-decade history. The effort to inhibit North Korea's pursuit of nuclear weapons is among the longest running and least successful sagas in international security and non-proliferation policy of the past quarter century. In early 2010, Pyongyang claims a rudimentary nuclear capability by possession of weaponized plutonium, the conduct of two nuclear tests, and advances in the production of enriched uranium as an alternative means of fissile material production, though the latter step is nominally justified as a source for reactor fuel. North Korea defends its pursuit of a nuclear deterrent to counter what Pyongyang deems existential threats posed by the United States.Despite the resumption of high-level diplomatic contact between Washington and Pyongyang in late 2009, realization of a non-nuclear Korean Peninsula remains a very remote prospect. The DPRK insists that a peace agreement between the U.S. and North Korea and hence the cessation of 'hostile DPRK-U.S. relations' are necessary before any consideration of

  7. Lithospheric models of the North American continent

    Tesauro, Magdala; Kaban, Mikhail; Mooney, Walter; Cloetingh, Sierd

    2015-04-01

    We constructed NACr14, a 3D model of the North American (NA) crust, based on the most recent seismic data from the USGS database. In comparison with the global crustal model CRUST 1.0, NACr14 is more heterogeneous, showing a larger spatial variability of the thickness and average velocities of the crustal layers. Velocities of the lower crust vary in a larger range than those of the other layers, while the thickness of all the three layers is on average between 11 and 13 km. The largest velocities of the crystalline crust (>6.6 km/s) reflect the presence of a 7.x layer (>7.0 km/s) in the lowermost part of the crust. Using NACr2014, a regional (NA07) and a global (SL201sv) tomography model, and gravity data, we apply an iterative technique, which jointly interprets seismic tomography and gravity data, to estimate temperature and compositional variations in the NA upper mantle. The results obtained demonstrate that temperature of the cratonic mantle is up to 150°C higher than when using a uniform compositional model. The differences between the two tomography models influence the results more strongly than possible changes of the depth distribution of compositional variations. Strong negative compositional density anomalies, corresponding to Mg # >92, characterize the upper mantle of the northwestern part of the Superior craton and the central part of the Slave and Churchill craton. The Proterozoic upper mantle of the western and more deformed part of the NA cratons, appears weakly depleted (Mg# ~91) when NA07 is used, in agreement with the results based on the interpretation of xenolith data. When we use SL2013sv, the same areas are locally characterized by high density bodies, which might be interpreted as the effect due to fragments of subducted slabs, as those close to the suture of the Appalachians and Grenville province. We used the two thermal models to estimate the integrated strength and the effective elastic thickness (Te) of the lithosphere. In the

  8. SRP Meeting: North west regional conference

    The SRP North West Regional Conference was held in the Education Centre, Christie Hospital NHS Trust in Manchester on the subject of Ionising Regulations 1999 (IRR99) two years on. The Chairman for the morning session was David Abbott from BNFL and for the afternoon was Anne Walker from Christie Hospital. Dr Joanne Nettleton, a HM Principal Specialist Inspector (Radiation) in the Field Operations Directorate, explained the view of the HSE. She outlined that the IRR99 have been in force since January 2000 after a comprehensive consultation exercise. The results that have been seen to date are, not surprisingly, no increase in exposure levels, an increased profile of radiation protection and an improved standing of RPAs. The SRP run a Continuing Professional Development scheme as a personal aid to maintain an adequate level of professionalism, demonstrate competence and as a guide to employers for them to maintain a professional Radiation Protection Service. There are currently over 300 people using the SRPs CPD scheme. They have also detailed a new mentoring system. In conclusion RPA 2000 is successfully meeting the needs of RPAs in the UK and the portfolios of evidence are improving. Overall, the SRP CPD scheme is effective and cheap. David Owen, Radiological Protection Manager responsible for policy and strategy issues in this field, gave a summary of the operation of the BNFL RPA Assessment Scheme, of which he is Secretary to the Management Board. The BNFL RPA Assessment Scheme is recognised by the HSE and has a number of subtle differences from the RPA 2000 scheme. RPAs advise on the restriction of exposure, designation of area, local rules, selection of the RPS, the training of the RPS and other staff, hazard identification, risk assessment, facility design, contingency planning, waste management and transport and any other matters relating to ionising radiation. Becoming an RPA within the medical sector is not easy. Firstly there is two years basic training

  9. Direct Experimental Assessment of Microbial Activity in North Pond Sediments

    Ferdelman, T. G.; Picard, A.; Morando, M.; Ziebis, W.

    2009-12-01

    North Pond, an isolated sediment pond located at 22°45’N on the western flank of the Mid-Atlantic Ridge, offered the opportunity to study microbial activities in deeply-buried low-activity sediments. About 8 x 15 km in size with sediment maximum thickness of about 300 m, North Pond is completely surrounded by exposed 7 Ma old basement. North Pond lies above the carbonate compensation depth at a water depth about 4500 m; hydrostatic pressure at the seafloor is about 45 MPa and the temperature is near 2°C. During the a R/V MS Merian cruise (MSM-11/1) in February -March 2009, 14 gravity cores of up to 9 m length were successfully obtained, from which samples were taken with 1-m resolution for experimental activity measurements. The goal of the experimental work was 1) to examine potential metabolic pathways in North Pond sediments and carbon assimilation pathways in this low-energy environment, and 2) explore the effects of pressure on microbial metabolic activities. As dissolved oxygen penetrated through all depths, sediments were aerobically sampled, processed and incubated at 4°C. Selected samples were immediately stored at in situ pressure until further use. The microbial uptake of both organic and inorganic carbon in selected North Pond sediment samples was investigated by following the fate of 14C in radio-labeled organic and organic compounds in North Pond sediment slurry incubations. Shipboard and on-shore experiments using 14C-leucine, 14C-glucose and 14C-bicarbonate were performed on selected cores. Day- to month- incubations were performed at 4°C. Parallel incubations were conducted at atmospheric pressure (0.1 MPa) and in situ pressure (~45 MPa). Either whole cell extraction (Kallmeyer et al., Limnol. Oceanogr.: Methods 6, 2008, 238-245) or protein-DNA extraction was carried on after various incubations to determine the fraction of 14C incorporated into cellular components. Formation of 14C-labeled CO2 was determined on samples incubated with 14C

  10. The Potential for Wave Energy in the North Sea

    Sørensen, H. C.; Chozas, Julia Fernandez

    2010-01-01

    The North Sea has not yet been regarded as prime area for wave energy development in Europe except in Denmark, Benelux and Germany. The reason is the relatively low intensity of waves (12-17kW/m) compared to the Atlantic with a wave climate of 24-48kW/m. Further on the design wave load is almost...... as in the Atlantic and the distance to shore relatively long compared to sites with good wave climate like Ireland, Portugal, Spain and the west coast of UK. The increasing activities within offshore wind in the North Sea and the attempt to build a super grid connecting the wind sites with the major consumers around...... the North Sea are expected to change the priority in favour of utilising wave energy from the North Sea. The paper describes the opportunities for power production in the North Sea considering the competition for space and the synergy with offshore wind. Two approaches are used: a traditional national...

    2015-01-01

    In North China, the Mesozoic terrestrial basins, sedimentary palaeogeography and tectonic settings involved ifve evolutionary stages:(1) the Early-Middle Triassic, (2) the Late Triassic to Early-Middle Jurassic, (3) the Late Jurassic to early Early Cretaceous, (4) the middle-late Early Cretaceous and (5) the Late Cretaceous. The regional punctuated tectonic events occurred during these evolutionary stages. During the Early-Middle Triassic (stage 1), the Xingmeng Orogenic Belt (XMOB, i.e., east-ern part of Central Asia Orogenic Belt, CAOB) of the northern North China was settled in the transition of tectonic environment from syn-orogenic compression to post-orogenic extension with intensive uplifting. It is a main provenance in the uniifed Ordos-North China Basin.The united continental plate of China and the Qinling-Dabie-Sulu Orogenic Belt formed due to convergence and collision between the North China Plate and the Yangtze Plate along two suture zones of the Mianlue and the Shangdan in the terminal Middle Triassic. During the Late Triassic to the Early-Middle Jurassic (stage 2), the Late Triassic maifc or alkaline rocks and intrusions occurred on the northern and southern margins of North China Craton (NCC) and XMOB, implying that intensiifed extension happened all over the North China (early phase of stage 2). Additionally, in the late phase of stage 2, the basic volcanic-iflling faulted basins were widely distributed in the northeastern North China during the Early-Middle Jurassic, including a series of small-to medium-sized basins with coal-bearing strata and some volcanic rocks in other areas of North China, which was the result of subduction of the Palaeo-Paciifc Plate during the Early-Middle Jurassic. An active continental margin with accretionary complex developed in the eastern Heilongjiang of China, Japan and the Far East of Russia at that time. However, in the end of the Early-Middle Jurassic, because of the Yan-shanian orogeny characterized by

  12. High temperature solar thermal technology: The North Africa Market

    1990-12-01

    High temperature solar thermal (HTST) technology offers an attractive option for both industrialized and non-industrialized countries to generate electricity and industrial process steam. The purpose of this report is to assess the potential market for solar thermal applications in the North African countries of Algeria, Egypt, Morocco and Tunisia. North Africa was selected because of its outstanding solar resource base and the variety of applications to be found there. Diminishing oil and gas resources, coupled with expanding energy needs, opens a large potential market for the US industry. The US high temperature solar trough industry has little competition globally and could build a large market in these areas. The US is already familiar with certain solar markets in North Africa due to the supplying of substantial quantities of US-manufactured flat plate collectors to this region.

    Serletis, Apostolos; Rangel-Ruiz, Ricardo [Calgary Univ., Dept. of Economics, Calgary, AB (Canada)

    2004-05-01

    Using recent advances in the field of applied econometrics, we explore the strength of shared trends and shared cycles between North American natural gas and crude oil markets. In doing so, we use daily data from January 1991 to April 2001 on spot U.S. Henry Hub natural gas and WTI crude oil prices. The results show that there has been 'decoupling' of the prices of these two sources of energy as a result of oil and gas deregulation in the United States. We also investigate the interconnectedness of North American natural gas markets and find that North American natural gas prices are largely defined by the U.S. Henry Hub price trends (Author)

  14. Ice flux divergence anomalies on 79north Glacier, Greenland

    Seroussi, H.; Morlighem, M.; Rignot, E.;

    2011-01-01

    The ice flux divergence of a glacier is an important quantity to examine because it determines the rate of temporal change of its thickness. Here, we combine high-resolution ice surface velocity observations of Nioghalvfjerdsfjorden (79north) Glacier, a major outlet glacier in north Greenland, with...... a dense grid of ice thickness data collected with an airborne radar sounder in 1998, to examine its ice flux divergence. We detect large variations, up to 100 m/yr, in flux divergence on grounded ice that are incompatible with what we know of the glacier surface mass balance, basal mass balance and...... onto a regular grid using a scheme (here block kriging) that does not conserve mass or ice flux. This problem is not unique to 79north Glacier but is common to all conventional ice thickness surveys of glaciers and ice sheets; and fundamentally limits the application of ice thickness grids to high...

  15. Decadal predictions of the North Atlantic CO2 uptake

    Li, Hongmei; Ilyina, Tatiana; Müller, Wolfgang A.; Sienz, Frank

    2016-03-01

    As a major CO2 sink, the North Atlantic, especially its subpolar gyre region, is essential for the global carbon cycle. Decadal fluctuations of CO2 uptake in the North Atlantic subpolar gyre region are associated with the evolution of the North Atlantic Oscillation, the Atlantic meridional overturning circulation, ocean mixing and sea surface temperature anomalies. While variations in the physical state of the ocean can be predicted several years in advance by initialization of Earth system models, predictability of CO2 uptake has remained unexplored. Here we investigate the predictability of CO2 uptake variations by initialization of the MPI-ESM decadal prediction system. We find large multi-year variability in oceanic CO2 uptake and demonstrate that its potential predictive skill in the western subpolar gyre region is up to 4-7 years. The predictive skill is mainly maintained in winter and is attributed to the improved physical state of the ocean.

  16. Tobacco Control: From North Karelia to the National Level.

    Heloma, Antero; Puska, Pekka

    2016-06-01

    After World War II, smoking among men was very common in Finland, and especially in North Karelia, contributing to the high rates of cardiovascular diseases and cancer. Thus, the North Karelia Project, from its very start in 1972, took reduction in smoking as one of its main targets. After 1977, the project actively contributed to national tobacco control work, including comprehensive legislation and many other activities. Smoking in North Karelia declined initially much more than in the rest of Finland, but thereafter there has been a steady national decline, resulting in a prevalence of daily smoking among adults of approximately 15% and contributing to the big reduction in the rates of heart disease and tobacco-related cancers, especially among men.

  18. Lianas as invasive species in North America: Chapter 28

    Leicht-Young, Stacey A.; Pavlovic, Noel B.

    Liana diversity is typically low in the temperate zones; however, the influx of non-native invasive liana species in North America has increased local diversity at the expense of native habitats and species. Some of the most illustrative studies of invasive lianas in temperate North America compared the biological traits of invasive lianas with native congeners or ecological analogs. The majority of these studies focused on two species, Celastrus orbiculatus (oriental bittersweet) and Lonicera japonica (Japanese honeysuckle). Temperate zone lianas generally have higher photosynthetic rates than other early successional species and their host trees. Invasive lianas are having an increasing impact on the dynamics and trajectories of North American plant communities. They often exhibit superior growth and survival compared to their native counterparts, and in some cases, invasive lianas may directly contribute to the decline of their native correlates.

  19. Solar Influence on the North Atlantic Oscillation - Initial Results

    Some initial investigations into various atmospheric phenomena and the influence of the solar cycle on weather have been made. Strongly negative North Atlantic Oscillation (NAO) indices, which cause cold and dry winter weather in North West Europe, rarely occur during periods of high solar activity. Coupling between the troposphere and stratosphere is discussed, particularly in the context of Polar-night jet oscillation events (defined by Hitchcock et al., 2013) and the Quasi-Biennial Oscillation. The energy of North Atlantic hurricanes (as indicated by the Accumulated Cyclone Energy Index, ACE) is also linked to solar activity, via UV heating at the tropopause (Elsner et al., 2010), and is suggested as a possible mechanism through which solar activity could influence the NAO. Finally the lack of solar influence on the NAO before $\\sim$ 1950 is addressed, with a possible cause being the smaller solar cycle amplitudes. This short report contains several ideas, which may be worth pursuing further.

  20. The Digital North Denmark Programme -Promoting Regional Change?

    The Digital North Denmark (DDN) was an IT programme running from 2000 to 2003 in the North Jutland County in Denmark with national government support of € 23 million. The Danish government initiated the programme with the aim of further strengthening regions with an already proven ICT capability...... (Dybkjær and Lindegaard, 1999, p.96-100). The declared approach was to build on the existing competencies in industry as well as at universities. The national government chose two regions – Ørestaden, a new concentration of knowledge-based institutions near Copenhagen Airport, and North Jutland. The...... profile of the programme changed from focusing on localised change targeting the producers of ICT in the region, to be initiated as a radical change project focusing on the users. In addition to the more historical accounts for DDN the actual implementation will also be analysed. The analyses of...
