Full Text Available Recovery of sorghum (Sorghum bicolor [L.] Moench production capacity in degraded vertisols in the Far North Region of Cameroon. In Northern Cameroon, degraded soils represent 10 to 20% of arable land. Recovering the production capacity of these degraded soils is one of the main challenges faced by agriculture in the region. The objective of the present study, conducted from 2007 to 2009, was to examine the possibility of growing sorghum on degraded and bare vertisols. A combination of the following techniques was used in a randomized complete block design: two land preparation techniques (plowing or mounding, two levels of cow dung dust (6 or 12 t·ha-1 and three rates of urea application (0, 50 or 100 kg·ha-1. The soil was sampled at a depth of up to 25 cm and was analyzed for its properties following standard analytical procedures. Critical levels established for tropical soils were used to declare sufficiency or deficiency of soil nutrients within the samples. Sorghum straw and grain yields were obtained and analyzed. Soil characteristics were found to be similar to those of other degraded vertisols found in the Far North Region of Cameroon. The hard top soil layer was found to be unfavorable to the establishment of sorghum. On the other hand, levels of organic carbon (0.85% and the sum of cations (4.91 meq·100 g-1 of soil were found to be favorable. The ratio of cations was found to be unfavorable to Ca. Available phosphorus (5.35 mg·kg-1 of soil and total N (0.04 g·kg-1 were very low. Following the application of treatments, 2.4 to 3.5 t·ha-1 of sorghum straw were produced and 1.3 to 2.8 t·ha-1 of grain were harvested during the experimental period. Soil plowing and mounding successfully disturbed the hard top soil layer. Soil mounding resulted into in a 16% increase in straw production in comparison with soil plowing alone. The application of 12 t·ha-1 of cow dung dust produced an additional grain yield of 17% in 2008 and of 39% in

There are continued concerns on unscientific usage of chemical fertilizers and pesticides, particularly in many developing countries leading to adverse consequences for soil biological quality and agricultural sustainability. In farmers' fields in tropical Vertisols of peninsular India, "high" fertilizer and pesticide usage at about 2.3 times the recommended rates in black gram (Vigna mungo) did not have a deleterious effect on the abundance of culturable microorganisms, associative nitrogen fixers, nitrifiers, and 16S rRNA gene diversity compared to normal rates. However, "very high" application at about five times the fertilizers and 1.5 times pesticides in chilies (Capsicum annuum) adversely affected the populations of fungi, actinomycetes, and ammonifiers, along with a drastic change in the eubacterial community profile and diversity over normal rates. Actinobacteria were dominant in black gram normal (BG1) (47%), black gram high (BG2) (36%), and chili normal (CH1) (30%) and were least in chili very high (CH2) (14%). Geodermatophilus formed 20% of Actinobacteria in BG1 but disappeared in BG2, CH1, and CH2. Asticcacaulis dominated at "very high" input site (CH2). Diversity of nitrogen fixers was completely altered; Dechloromonas and Anaeromyxobacter were absent in BG1 but proliferated well in BG2. There was reduction in rhizobial nifH sequences in BG2 by 46%. Phylogenetic differences characterized by UniFrac and principal coordinate analysis showed that BG2 and CH2 clustered together depicting a common pattern of genetic shift, while BG1 and CH1 fell at different axis. Overall, there were adverse consequences of "very high" fertilizer and pesticide usage on soil microbial diversity and function in tropical Vertisols.

The Yellow Cat Member of the Cedar Mountain Formation in Poison Strip, Utah, USA, consists of stacked, erosionally bounded alluvial sequences dominated by massive mudstones (lithofacies Fm) with paleo-Vertisols. Sediment bodies within these sequences grade vertically and laterally into each other at pedogenic boundaries, across which color, texture, and structures (sedimentary vs. pedogenic) change. Slickensides, unfilled (sealed) cracks, carbonate-filled cracks, and deeper cracks filled with sandstone; the latter features suggest thorough desiccation during aridification. Thin sandstones (Sms) in some sequences, typically as well as laminated to massive mudstones (Flm) with which they are interbedded in some cases, are interpreted as avulsion deposits. The termini of many beds of these lithofacies curve upward, parallel to nearby pedogenic slickensides, as the features we call ;turnups.; Turnups are overlain or surrounded by paleosols, but strata sheltered underneath beds with turnups retain primary sedimentary fabrics. Turnups were produced by movement along slickensides during pedogenesis, by differential compaction alongside pre-existing gilgai microhighs, or by a combination of both. Palustrine carbonates (lithofacies C) appear only in the highest or next-highest alluvial sequences, along with a deep paleo-Vertisol that exhibits partially preserved microrelief at the base of the overlying Poison Strip Member. The attributes of the Yellow Cat Member suggest comparatively low accommodation, slow accumulation, long hiatuses in clastic sedimentation, and substantial time intervals of subaerial exposure and pedogenesis; it appears to be distinct among the members of the Cedar Mountain Formation in these respects.

Zinc deficiency, a major problem in crops grown on soils low in available Zn, is even more important in phosphorus-rich soils. This work aimed to elucidate the effects of soil P and Zn levels, and of fertilizer application, on yield and Zn concentration in cereal grains. Wheat and barley were successively pot-grown on 20 calcareous Vertisols low in available Zn and ranging widely in available P. Grain yield in the plants grown on the native soils was positively correlated with Olsen P but not with diethylenetriaminepentaacetic acid (DTPA)-extractable Zn except for wheat on P-rich soils. Grain Zn concentration was negatively correlated with Olsen P. Grain Zn uptake differed little among soils. Application of P to the soils increased grain yield insignificantly and P concentration significantly; however, it reduced grain Zn concentration (particularly at low Olsen P values). Applying Zn alone only increased grain Zn concentration, whereas applying P and Zn in combination increased yield and grain Zn concentration at low and high Olsen P values, respectively. Applying P alone to plants grown on calcareous Vertisols low in available P and Zn may in practice reduce grain Zn concentrations while not increasing grain yield significantly. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

2007-01-01

A short-term greenhouse pot culture study was carried out to study the agronomy efficacy of P sources for cotton crop in a vertisol. The sources of P were single super phosphate (SSP), diammonium phosphate (DAP) and nitrophosphate tagged with 32 P and applied at three rates (30, 60 and 90 kg P 2 O 5 ha -1 ). The results indicated that the dry matter yield (DMY) of cotton shoot, P uptake, percent P derived from fertilizer (%Pdff) and Avalue of the soil increased significantly with increasing fertilizer rate, whereas the percent fertilizer P utilization (%FUP) was found to be higher at lower fertilizer rates. Among the fertilizer sources SSP was found to be superior in enhancing DMY of cotton, P uptake and %FUP as compared to other fertilizers. %Pdff was found to be at par in SSP and DAP treatments and was significantly higher in comparison to NP and reverse was true in case of A-value of the soil. Results on equivalent ratio showed that SSP and DAP are equally efficient, whereas, 1 kg P as SSP was equivalent to 7.47 kg P as NP. In general, efficacy of phosphatic fertilizers for cotton crop in vertisol was found to be in order of SSP>DAP>NP. (author)

The parameters of the atrazine migration in columns with undisturbed Vertisol sampled from an irrigated plot in Guanajuato, Mexico were determined. A model of the convection-dispersion transport of the chemical compounds accounting for the decomposition and equilibrium adsorption, which is widely applied for assessing the risk of contamination of natural waters with pesticides, was used. The model parameters were obtained by solving the inverse problem of the transport equation on the basis of laboratory experiments on the transport of the 18O isotope and atrazine in soil columns with an undisturbed structure at three filtration velocities. The model adequately described the experimental data at the individual selection of the parameters for each output curve. Physically unsubstantiated parameters of the atrazine adsorption and degradation were obtained when the parameter of the hydrodynamic dispersion was determined from the data on the 18O migration. The simulation also showed that the use of parameters obtained at water content close to saturation in the calculations for an unsaturated soil resulted in the overestimation of the leaching rate and the maximum concentration of atrazine in the output curve compared to the experimental data.

Full Text Available Soil fertility is a crucial factor determining the growth and yield of plants. The increase of nutrient content and availability in soil can be achieved by fertilization. A field experiment was conducted using a Randomized Completely Block Design (RCBD with two factors and three replications in order to study the effects of Mixed Source of Fertilizer (MSF application on the nutrient contents in Vertisol and its relationship to the growth and yield of mustard. The first factor was the three MSF formulas (F1, F2, F3 and second factor was the doses of MSF (0; 2.5; 5.0; 7.5; 10 Mg ha-1 applied to the soil. At the end of the experiment, the soil pH, CEC, organic-C, total-N, available-P and exchangeable-K contents were measured. The results show that there are no significant differences on the soil chemical characteristics, such as pH, organic-C content, available-P, exchangeable-K, -Ca and -Mg measured after application of different MSF formulas to the soil. Meanwhile, the increase of MSF doses applied to the soil significantly increases organic-C content, total-N, available-P and exchangeable-K in the soil. The significant increase of available-P (by 29.13% and total-N (by 24.1% occured after application of MSF at 5.0 Mg ha-1 and the increase of exchangeable-K (by 50% is achieved after application of 7.5 Mg ha-1, in comparison to that without MSF application. The height and fresh weight of mustard increase in accordance with the increase of MSF doses applied. The application of 10.0 Mg ha-1 MSF results in the highest height and fresh weight of the mustard up to 63.9% and 620%, respectively. The height and fresh weight of mustard are positively correlated to the total-N, available-P and exchangeable-K in the soil. The MSF is an alternative fertilizer that can be used to improve Vertisol fertility and plant growth.

Full Text Available BACKGROUND Dental caries is a universal health problem with involving the people globally of all regions and society. The agonising fact is that despite several efforts towards total eradication, dental caries is still prevalent. As the prevalence of dental caries is very high among school children and there is a paucity of such data in Coimbatore and the literature review does not reveal many such studies from this area, the study was conducted in the school going children in Sulur. MATERIALS AND METHODS All the students were screened visually using torch with the help of mouth mirror and probe and the observation recorded. A health screening camp was conducted for the students in private school, Sulur, February 20-25, 2017, by a team of doctors from PSG UHTC. A total of 1945 students were screened. The students health details have been entered in their health card and those requiring further evaluation have been counseled and the nursing staff at school has been requested to facilitate and guide for followup. All the students were screened visually using torch with the help of mouth mirror and probe and the observation recorded. All the students who were present in school during 20th to 25th were screened and considered as the inclusion criteria. The exclusion criteria were the absentees during this period. The students were made to sit in an ordinary chair in broad daylight facing away from the sunlight and examined in their school. Data were compiled in an excel worksheet and the percentage calculated. RESULTS A total of 1945 students were screened, of which, 541 students were found to have dental problems that is about 28% of the total screening done. The percentage of dental caries were found to be higher compared to other dental diseases like deep caries, malalignment, malocclusion and calculus. The percentage of dental caries was found to be higher in the females about 78% than the male for whom it was about 72%. The percentage of deep

Cabezas, Jose Manuel; Gómez, Jose Alfonso; Auxiliadora Soriano, María

2016-04-01

Soil water availability is a major subject in Mediterranean agricultural systems, mainly due to the limited and highly variable annual rainfall, high evaporative demand, and soil hydrological characteristics. The recent expansion of olive cultivation in the rolling-plains of the Guadalquivir valley, due to the higher profitability of new intensive olive orchards, expanded the presence of olive orchards on Vertisols, soils traditionally used for annual rain-fed crops. These soils have a high content of smectitic clays, which give them a high water storage capacity, and are characterized by vertical and deep shrinkage cracks in the dry season, associated to low soil moisture. Farmers make several tillage passes in these olive groves during the summer, in order to cover the cracks and thus reduce soil water loss by evaporation, which will impact especially in rain-fed in the next olive yield. This tillage practice involves removal of plant residues from the soil surface, as well as burying seeds produced by the plants, so this will remain bared at the beginning of the rainy season, when in the Mediterranean climate is frequent occurrence of high-intensity rainfall, which are ideal conditions for soil loss by water erosion, one of the most serious problems for the sustainability of olive cultivation in Andalusia. Although there are some studies showing that water loss by evaporation from deep horizons of a vertic soil might be elevated (eg. Ritchie and Adams, 1974), the presence of plant residues on the soil surface drastically reduced soil water loss (eg Adams et al., 1969). Thus the aim of this study was to assess of soil moisture dynamics in a rain-fed olive orchard growing on a Vertisol under different soil management practices, in Andalusia (southern Spain). Four different soil management treatments were applied, which combined a cover crop (Bromus rubens L.) or bare soil throughout the year by applying herbicides, with tillage in summer to cover the cracks or non

Incidences of mortality of Indian peafowl Pavo cristatus, the national bird (Schedule I Indian Wild Life Protection Act 1972), are rampant in India. Between January 2011 and March 2017, around 550 peafowl in 35 incidences were reported dead across the country. Due to the non-availability of fresh carcases, poisoning could not be confirmed. Birds which died due to kite string injuries in Ahmedabad (15) and accidents in Coimbatore (5) were tested for residues of chlorinated pesticides, namely hexachlorocyclohexane (HCH), dichloro-diphenyl-trichloroethane (DDT), endosulfan, heptachlor, dicofol, dieldrin and cholipyrifos. The liver, kidney and muscle were the tissues considered to document pesticide load. Total load ranged from BDL to 388.2 ng/g. DDT (95%) and HCH (80%) were detected more frequently. DDT (40%) and endosulfan (26%) contributed maximum to the total pesticide load followed by HCH (21%). Pesticide accumulation pattern among the organs was in the order of liver (123.9 ng/g) > kidney (91.9 ng/g) > muscle (19.5 ng/g) with significant difference (p pesticide (149.0 ng/g) than birds from Coimbatore (47.8 ng/g). Although varying levels of chlorinated pesticide were detected, they were below reported toxic limits. Nevertheless, persistence of chlorinated pesticides and poisoning due to modern pesticides across the entire distribution range of Peafowl in India is a cause for concern.

The effect of a second dose of vinasse on some physical and chemical properties of a Vertisol was evaluated with cut sugarcane in Valle del Cauca, Colombia. We analyzed the expression of any possible toxicity in foliar tissue samples at the end of the cycle. Vinasse treatments added with two different mixtures of microorganisms were established in a randomized complete block with five replicates: soil without vinasse and no microorganisms; soils with a dose of vinasse, soils with two doses of vinasse; soils with a single dose of vinasse separately evaluated with two different mixtures of microorganisms and soils with two doses of vinasse separately evaluated with two different mixtures of microorganisms. The chemical properties evaluated were pH, soil organic matter content, C, N, P, Ca, Mg, Na, and K content, cation exchange capacity CEC and electrical conductivity EC. The physical properties determined were bulk density, particle density and porosity. There were no significant differences in the physical and chemical properties of the soil for the evaluated cultivation cycle with the application of one or two doses of vinasse with and without microorganisms. Leaf tissue analysis did not show a nutritional imbalance due to the second application.

Unique water transfer and retention properties of Vertisols strongly affect their use in rainfed agriculture in water-limited environments. Despite the agricultural importance of the hydraulic properties of those soils, water retention data dryer than the wilting point are generally scarce, mainly as a result of practical constraints of traditional water retention measurement methods. In this work we provide a detailed description of regionalized water retention data from saturation to oven dryness, obtained from 54 minimally disturbed topsoil (0-0.05m) samples collected at a 3.5-ha experimental field in SW Spain where conventional tillage (CT) and direct drilling (DD) is compared in a wheat-sunflower-legume crop rotation on a Vertisol. Water retention was measured from saturation to oven dryness using sand and sand-kaolin boxes, a pressure plate apparatus and a dew point psychrometer, respectively. A common shape of the water retention curve (WRC) was observed in both tillage systems, with a strong discontinuity in its slope near -0.4 MPa and a decreasing spread from the wet to the dry end. A continuous function, consisting of the sum of a double exponential model (Dexter et al, 2008) and the Groenevelt and Grant (2004) model could be fitted successfully to the data. Two inflection points in the WRC were interpreted as boundaries between the structural and the textural pore spaces and between the textural and the intra-clay aggregate pore spaces. Water retention was significantly higher in DD (ptillage and compaction, increasing and decreasing the amount of the largest pores in CT and DD, respectively, but resulting in a proportionally larger pore space with relevant pore-sizes for water dynamics and agronomic performance. Significant differences in water retention and equivalent pore-sizes at the dry end of the WRC could be associated with the higher organic matter content found in DD. These results explain the superior performance of DD over CT in satisfying

Full Text Available Metal contamination of soil due to industrial and agricultural activities is increasingly becoming a global problem, thereby affecting animal and human life, thus rendering soil unsuitable for agricultural purposes. Remediation of cadmium (Cd contaminated soil (Vertisol using agricultural by products as source of organic amendments, Coir pith- a by-product of the coir industry and Prosopis charcoal- prepared by burning Prosopis plant wood (Prosopis juliflora L. was investigated. The alleviation potential of Prosopis charcoal and Coir pith on the negative effects of Cd in soil was evaluated in pot culture experiments with Vigna radiata as the test plant, a Cd accumulator. Cadmium addition to soil resulted in accumulation of Cd in all plant parts of V. radiata predominantly in roots. The influence of Cd in the presence and absence of organic amendments on the various biological and chemical parameters of the soil, on the levels of Cd accumulation and on the growth attributes of V. radiata has been assessed. Among the organic amendments, Prosopis charcoal was found to be more effective in reducing the bioavailable levels of Cd in the soil artificially spiked with Cd in graded concentrations of 0, 5, 10, 20, 40, 60, 80 and 100 µg g-1 and its accumulation in V. radiata, thus resulting in an increase in the root, leaf and stem biomass. Coir pith, however, was effective in increasing the total mycorrhizal colonization of roots and second in reducing Cd levels in plants. Therefore, Prosopis charcoal was considered best for stabilization of Cd in soil.

In several areas of South America, the extensive cropping systems in traditional agricultural lands have increase the area cropped with soybean, mainly as a single annual crop. Also nowadays agriculture has a progressive expansion toward more environmentally fragile areas that were traditionally occupied by livestock or native forests. This change of land use may be characterized through different indexes as the length of the growth period or the frequency of a particular crop in the cropping sequence. On the other hand the consequences of land-use changes on soil physical condition may be monitored through the aggregate stability, which is directly related to soil functionality. However, there are different methods for aggregate stability analysis, which may vary in their potential for prediction. The aim of our work was to assess different quantitative indexes of change in the land use on aggregate stability through two methods in two soils differing in the main agents of aggregation. The study was conducted in a Mollisol and a Vertisol from Argentina. Eleven fields (agricultural and crop-pasture rotation) under no-tillage and one natural grassland were selected in each soil type. The fraction of annual time with vegetal cover (as a measure of the intensification in the land use - ISI) and the frequency of a given crop (soybean - SCF; wheat - WCF; and wheat plus maize - CCF) in the cropping sequence over a 6-year period were calculated. Samples were collected at 0-5 and 5-15 cm depths from each soil. The mean weight diameter (MWD) of the soil aggregates where determined by two methods: Le Bissonnais with three pretreatment (fast wetting, slow wetting and stirring after prewetting) and by wet sieving using an instrument similar to the Yoder apparatus. The MWD by wet-sieving was affected by ISI and SCF, but the impact only was recorded in 0-5cm depth of the Mollisol. The MWD by fast and slow wetting and the means of three pretreatments (MWDm) were directly related

Full Text Available Despite its very recent history of cultivation in Ethiopia, rice is one of the potential grain crops that could contribute to the efforts for the realization of food security in the country. However, the scientific information available with regards to the response of flooded rice to N and P fertilizers for its optimum production on Vertisols of Fogera Plain is very limited. Therefore, a field experiment was conducted on Vertisols of Fogera plain, northern Ethiopia to study the yield and yield components response of rice and to establish the optimum N and P fertilizer levels required for improved grain yield of flooded rice. Six levels of N (0, 30, 60, 90, 120 and 150 kg ha−1 and five levels of P (0, 13.2, 26.4, 39.6 and 52.8 kg ha−1 laid down in a randomized complete block design with four replications were used as treatments. Nitrogen was applied in two equal splits (50% basal and 50% at maximum tillering as urea and the entire dose of P was applied basal as triple super phosphate at sowing. The main effects of N and P fertilizer levels showed significant differences (P ≤ 0.01 for all yield and yield components studied. The effects of N by P interaction were significant only for grain yield (P ≤ 0.05, number of panicles per m2 (P ≤ 0.01, number of spikelets per panicle (P ≤ 0.05 and plant height (P ≤ 0.01 among the different yield and yield components studied. Application of N and P significantly (P ≤ 0.01 increased grain yield of rice up to the levels of 60 kg N and 13.2 kg P ha−1. However, maximum grain yield (4282 kg ha−1 was obtained with the combined application of 60 kg N and 13.2 kg P ha−1, and the yield advantage over the control was 38.49% (1190 kg ha−1. Moreover, application of both N and P fertilizers have increased the magnitudes of the important yield attributes including number of panicles per m2, number of spikelets per panicle, panicle length, dry matter accumulation, straw yield and plant height

The effects of electrolyte concentration (C) and sodium adsorption ratio (SAR) on zinc sorption was studied. Top soil samples (0-30 cm) were taken from soils representing three arid-zon smectitc sites in the Gezira Scheme (Sudan). The orders of these soils are vertisol (El-Hosh (now Wad El Ataya) and El-Suleimi) and aridisol (El-Laota). These soils had no previous history of zinc application, and were previously equilibrated with mixed NaCl-CaCl 2 solutions to render different levels of SAR and salt concentration. Zinc retention decreased as electrolyte concentration increased, where maximum sorption occurred at low electrolyte concentration soils having high pH and high negative charge. Sodium adsorption ratio had little effect on Zn sorption as precipitation prevailed at high pH. It was also found that the sorption capacity of three soils were similar despite the variation in CaCO 3 and clay contents, hence cation exchange capacity and surface area. The results indicated that Zn was more soluble in the saline phases of Gezira soils, whereas sodicity had little effect.(Author)

Full Text Available BACKGROUND Obesity is a major concern in our era. Obese individuals have numerous physiological changes which predispose them to many dermatological conditions. This study was done to find the common dermatoses associated in adults with a BMI of > 30 kg/m2 who presented to the Skin Outpatient Department of Coimbatore Medical College Hospital. OBJECTIVES To study the prevalence of various dermatological manifestations of obesity, age, sex distribution, morphology of individual lesions associated with obesity and their association with BMI and lipid profile. METHODOLOGY This is a descriptive study conducted from August 2014 to July 2015. Hundred patients with age > 12 yrs. and BMI > 30 kg/m2 were selected and included in the study. Diabetes was ruled out and lipid profile was carried out for all patients. Other necessary investigations like biopsy, KOH mount and immunofluorescence were done for relevant cases. RESULTS There were 100 patients with 169 dermatoses seen in the study. Male female ratio was 1.5: 1. Most cases belonged to the age group of 31-40. Nearly 76% all cases were in grade 1 obesity according to their BMI levels. Only 3 cases were seen in grade 3 obesity. Lipid profile alterations were seen in 29% of all cases. Skin tag was the most common dermatosis seen in the study followed by acanthosis nigricans, plantar hyperkeratosis and striae. CONCLUSION Severity of obesity also determines the nature of lesions occurring in the patients. Early identification of these conditions can be useful in preventing the deleterious effects of obesity on the body. Treatment of lipid profile abnormalities in addition to weight reduction can decrease the occurrence of these dermatoses.

2018-01-01

Full Text Available Comprehensive Environmental Pollution Index (CEPI is a rational number to characterize the quality of the environment at a given location following the algorithm of source, pathway, and receptor. As CEPI increases, there will be adverse effectson the receiving environment. Central Pollution Control Board (CPCB has brought out revised criteria for evaluation of CEPI by replacing the criteria issued in 2010. The revised criteria are issued to overcome the subjectivity factors of health impact studies on humans, floraand fauna. Kurichi Industrial Cluster in Coimbatore District is an engineering industrial estate housing foundries, forging units, metal finishingand fabrication units. In January 2010, the Ministry of Environment and Forests, Government of India declared Kurichi as critically polluted area and imposed moratorium on new projects and for expansion of the existing units. This declaration was made based on the CEPI score which was calculated as more than 70. Thereafter, the industries and the local stake holders have implemented various pollution control measures and hence the CEPI score has come down less than 70 and so the moratorium was lifted in October 2010. In this paper, the CEPI score is calculated based on the revised criteria and using the environmental quality monitoring data collected in April 2017. It is found that the CEPI score is below 70 which imply that the industrial units are operating and maintaining the pollution control measures consistently. However, taking a policy decision based on the CEPI score, one should be cautious on the adequacy of data and the parameters selected.

2001-01-01

Using the tropical soil biology and fertility (TSBF) methodology the biodiversity, the density and biomass of macrofauna was evaluated in a vertisol soil under four tillage systems and in a cocoa plantation with an undisturbed for more than 20 years. Soil under cocoa showed the highest values of biodiversity (47 u.t.) while mulch tiller treatment showed the highest density (122 ind. 0.062 m 2 ) and direct seeding the highest value of biomass (5.44 g. 0.062 m 2 ). Ants, Myriapods and earthworms exhibited greater level of population density (41 +/- 28; 15 +/- 8 and 8 +/- 5 ind. 0.062 m 2 , respectively) while the greatest contribution to biomass was made by earthworms and coleoptera population with 2.3 +/- 1.7 and 0.27 +/- 0.32 g. 0.062 m 2 . Soil under cocoa plantation and direct seeding presented the highest proportion of macrofauna at the top 5 cm (58.2 and 51.1 % respectively) while treatments with soil disturbance as mulch tiller, disk plowing and chisel plow the distribution of macrofauna was between 5 to 20 cm depth (55.8,53.7 and 46.2 %). this study evidenced the sensibility of the soil's macrofauna to different tillage systems. Macrofauna quantifying could be used to evaluate soil conditions under different management methods

1996-01-01

The significance of double crop (intercrop and sequential crop), single crop (rainy season crop fallow from June to September), and rotations on densities of Heterodera cajani, Helicotylenchus retusus, and Rotylenchulus reniformis was studied on Vertisol (Typic Pellusterts) between 1987 and 1993. Cowpea (Vigna sinensis), mungbean (Phaseolus aureus), and pigeonpea (Cajanus cajan) greatly increased the population densities of H. cajani and suppressed the population densities of other plant-parasitic nematodes. Mean population densities of H. cajani were about 8 times lower in single crop systems than in double crop systems, with pigeonpea as a component intercrop. Plots planted to sorghum, safflower, and chickpea in the preceding year contained fewer H. cajani eggs and juveniles than did plots previously planted to pigeonpea, cowpea, or mungbean. Continuous cropping of sorghum in the rainy season and safflower in the post-rainy season markedly reduced the population density of H. cajani. Sorghum, safflower, and chickpea favored increased population densities of H. retusus. Adding cowpea to the system resulted in a significant increase in the densities of R. reniformis. Mean densities of total plant-parasitic nematodes were three times greater in double crop systems, with pigeonpea as a component intercrop than in single crop systems with rainy season fallow component. Cropping systems had a regulatory effect on the nematode populations and could be an effective nematode management tactic. Intercropping of sorghum with H. cajani tolerant pigeonpea could be effective in increasing the productivity of traditional production systems in H. cajani infested regions. PMID:19277141

Oxygation enhances growth, gas exchange and salt tolerance of vegetable soybean and cotton in a saline vertisol.

Bhattarai, Surya P; Midmore, David J

2009-07-01

Impacts of salinity become severe when the soil is deficient in oxygen. Oxygation (using aerated water for subsurface drip irrigation of crop) could minimize the impact of salinity on plants under oxygen-limiting soil environments. Pot experiments were conducted to evaluate the effects of oxygation (12% air volume/volume of water) on vegetable soybean (moderately salt tolerant) and cotton (salt tolerant) in a salinized vertisol at 2, 8, 14, 20 dS/m EC(e). In vegetable soybean, oxygation increased above ground biomass yield and water use efficiency (WUE) by 13% and 22%, respectively, compared with the control. Higher yield with oxygation was accompanied by greater plant height and stem diameter and reduced specific leaf area and leaf Na+ and Cl- concentrations. In cotton, oxygation increased lint yield and WUE by 18% and 16%, respectively, compared with the control, and was accompanied by greater canopy light interception, plant height and stem diameter. Oxygation also led to a greater rate of photosynthesis, higher relative water content in the leaf, reduced crop water stress index and lower leaf water potential. It did not, however, affect leaf Na+ or Cl- concentration. Oxygation invariably increased, whereas salinity reduced the K+ : Na+ ratio in the leaves of both species. Oxygation improved yield and WUE performance of salt tolerant and moderately tolerant crops under saline soil environments, and this may have a significant impact for irrigated agriculture where saline soils pose constraints to crop production.

Full Text Available Irrigation, when administered correctly, confers the producers the possibility to overcome drought effects and obtain higher yields, supplementing the quality of food for animals or human consumers. In the mean time, soil erosion, pathogens attack and nutrients or pesticides spreading can be prevented by an adequate management of irrigation water. As a consequence, soil microbial community structure, composition and activities, as well as the organic matter quality can be different from those in non-irrigated soil. Research have been carried out in order to assess changes in bacterial and fungal communities and activity in irrigated Vertisol from Boianu, as compared with non-irrigated. The paper presents the results concerning the taxonomical composition of bacterial and fungalmicroflora in the horizons of the two soil profiles, as well as the level of CO2 released by microorganisms. Chromatographic aspects of humus fractions were used to characterize the organic matter in irrigated and nonirrigated soil. Increased moisture and lowered temperature in Ap horizon of irrigated soil increased bacterial counts(18 x106 viable cells x g-1 dry soil and their metabolic activity expressed by carbon dioxide released (46.838mg CO2 x g-1 dry soil comparatively with non- irrigated soil. Fungal microflora was more abundant after 25-50cm under irrigation. Species diversity slightly increased under irrigation in both upper and lower part of soil profile. In irrigated soil, associations of species belonging to bacterial genera Pseudomonas and Bacillus were dominant in surface and white actinomycetes in the depth. Fungal consortia of Penicillium, Aspergillus and Fusarium dominated in both soil profiles.Irrigation induced changes in the quantity and quality of soil organic matter, as well as in the aspect of their migration pattern, as revealed on circular chromatograms.

Redistribution of magnetic iron oxide along soil profile after eight years managing a commercial olive orchard in a Vertisol

Science.gov (United States)

Guzmán, Gema; Gómez, José Alfonso

2017-04-01

Magnetic iron oxide has been used as a tracer to monitor top soil movement and to identify source of sediments at the short-term scale, after high intensity rainfall events (Guzmán et al., 2010; Obereder et al., 2016) and periods up to two years (Guzmán et al., 2013). As it can be strongly bound to soil particles, its use allows the tacking of tagged soil all over the years until all this soil is lost or it is totally diluted with blank soil making the signal undetectable. Olive orchards planted on Vertisols are subject not only to tillage operations modifying soil profile but also to expansion-compression cycles and cracks appearance due to soil moisture changes. The aim of communication is to assess the soil movement at the mid-term scale, taking advantage of a tracer trial already performed by Guzmán et al. (2013) and a new sampling after 8 years of soil disturbance. In October 2008 two plots of 330 m2 were delimited and in which the top 5 cm of the inter tree rows were tagged with magnetite. Seventy locations at both plots were sampled so as to measure magnetic susceptibility twice (just after the tagging and March 2010), at three depth intervals (0-1, 1-8 and 8-12 cm) and distinguishing two zones: tree and inter tree rows. A third sampling was carried out at 0-2, 2-10 and 10-20 cm in August 2016 at the same locations and zones. Furthermore, in twenty of the sampling points additional samples from 20-30, 30-40, 40-50 and 50-60 cm were taken to check if tagged soil went deeper into the soil profile. Background values of susceptibility and bulk density at each depth, were characterized as well at the three sampling campaigns. Rainfall, soil management during these years and the inherent characteristics of a Vertisol have enhanced the movement of top soil not only superficially but also within the soil profile. First results comparing the evolution of magnetite distribution along soil profile indicate that while in 2008 and 2010 background values were measured

Full Text Available The basaltic landscape planning on the hot semiarid ecosystem in cotton growing Yavatmal district, Maharashtra tends to concentrate on 52 per cent of total cultivated area with 43 per cent of rural families living below poverty line posing major problem for environmental protection and resource management. Concepts of sustainable development at regional-level planning suggested that there is a growing concern for the landscape community to develop a strategic regional agricultural planning perspective in order to assist landscape planning goals. These challenges were explored with particular reference to the cotton growing Yavatmal district in Maharashtra through baseline land resource / agronomic surveys and assessing the production potential of regional rural landscapes for crop planning. Landscape analysis, premised on the geopedological and elevation constructs, culminated in a spatial coverage of hills and ridges (12.6 per cent of total area in northern and central parts whereas plateaus (29.3 per cent in association with isolated hills, mesas and butte and escarpments (17.7 per cent, pediplains (28.8 per cent and plains (8.1 per cent in south western parts of the district. Regional level analysis revealed spatially variable soil typologies dominated by vertisols and vertic intergrades. An exploration and brief account of integration landscape planning was discussed with some reflections on the experience and highlighting some of the problems and potentials of this approach within the regional context.

The effect of changing environment on the evolution of Homo sapiens is heavily debated, but few data are available from equatorial Africa prior to the last glacial maximum. The Karungu deposits on the northeast coast of Lake Victoria are ideal for paleoenvironmental reconstructions and are best studied at the Kisaaka site near Karunga in Kenya (94 to > 33 ka) where paleosols, fluvial deposits, tufa, and volcaniclastic deposits (tuffs) are exposed over a 2 km transect. Three well-exposed and laterally continuous paleosols with intercalated tuffs allow for reconstruction of a succession of paleocatenas. The oldest paleosol is a smectitic paleo-Vertisol with saline and sodic properties. Higher in the section, the paleosols are tuffaceous paleo-Inceptisols with Alfisol-like soil characteristics (illuviated clay). Mean annual precipitation (MAP) proxies indicate little change through time, with an average of 764 ± 108 mm yr- 1 for Vertisols (CALMAG) and 813 ± 182 to 963 ± 182 mm yr- 1 for all paleosols (CIA-K). Field observations and MAP proxies suggest that Karungu was significantly drier than today, consistent with the associated faunal assemblage, and likely resulted in a significantly smaller Lake Victoria during the late Pleistocene. Rainfall reduction and associated grassland expansion may have facilitated human and faunal dispersals across equatorial East Africa.

Change Detection Analysis of Water Pollution in Coimbatore Region using Different Color Models

Science.gov (United States)

Jiji, G. Wiselin; Devi, R. Naveena

2017-12-01

The data acquired through remote sensing satellites furnish facts about the land and water at varying resolutions and has been widely used for several change detection studies. Apart from the existence of many change detection methodologies and techniques, emergence of new ones continues to subsist. Existing change detection techniques exploit images that are either in gray scale or RGB color model. In this paper we introduced color models for performing change detection for water pollution. Here the polluted lakes are classified and post-classification change detection techniques are applied to RGB images and results obtained are analysed for changes to exist or not. Furthermore RGB images obtained after classification when converted to any of the two color models YCbCr and YIQ is found to produce the same results as that of the RGB model images. Thus it can be concluded that other color models like YCbCr, YIQ can be used as substitution to RGB color model for analysing change detection with regard to water pollution.

Incorporation of organic waste amendments to a horticultural soil, prior to expected risk periods, could immobilise mineral N, ultimately reducing nitrogen (N) losses as nitrous oxide (N 2 O) and leaching. Two organic waste amendments were selected, a fresh green waste (FGW) and green waste compost (GWC) as they had suitable biochemical attributes to initiate N immobilisation into the microbial biomass and organic N forms. These characteristics include a high C:N ratio (FGW 44:1, GWC 35:1), low total N ( 14%). Both products were applied at 3 t C/ha to a high N (plus N fertiliser) or low N (no fertiliser addition) Vertisol soil in PVC columns. Cumulative N 2 O production over the 28 day incubation from the control soil was 1.5 mg/N 2 O/m 2 , and 11 mg/N 2 O/m 2 from the control + N. The N 2 O emission decreased with GWC addition (P 2 O emissions by 38% by the conclusion of the incubation. Analysis of mineral N concentrations at 7, 14 and 28 days identified that both FGW and GWC induced microbial immobilisation of N in the first 7 days of incubation regardless of whether the soil environment was initially high or low in N; with the FGW immobilising up to 30% of available N. It is likely that the reduced mineral N due to N immobilisation led to a reduced substrate for N 2 O production during the first week of the trial, when soil N 2 O emissions peaked. An additional finding was that FGW + N did not decrease cumulative N 2 O emissions compared to the control + N, potentially due to the fact that it stimulated microbial respiration resulting in anaerobic micro sites in the soil and ultimately N 2 O production via denitrification. Therefore, both materials could be used as post harvest amendments in horticulture to minimise N loss through nitrate-N leaching in the risk periods between crop rotations. The mature GWC has potential to reduce N 2 O, an important greenhouse gas.

On the distinction of tectonic and nontectonic faulting in palaeoseismological research: a case study from the southern Marmara region of Turkey

Özaksoy, Volkan

2017-12-01

This study reports on spectacular deformation structures, including arrays of striated thrusts, discovered by excavation work in Holocene deposits in vicinity of a major neotectonic strike-slip fault in one of the tectonically most active regions of Turkey. The deformation structures were initially considered an evidence of sub-recent tectonic activity, but their detailed multidisciplinary study surprisingly revealed that the deformation of the clay-rich soil and its strongly weathered Jurassic substrate was of nontectonic origin, caused by argilliturbation. This phenomenon of vertisol self-deformation is well-known to pedologists, but may easily be mistaken for tectonic deformation by geologists less familiar with pedogenic processes. The possibility of argilliturbation thus needs to be taken into consideration in palaeoseismological field research wherever the deformed substrate consists of clay-rich muddy deposits. The paper reviews a range of specific diagnostic features that can serve as field criteria for the recognition of nontectonic deformation structures induced by argilliturbation in mud-dominated geological settings.

Effects of biochar and clay amendment on nutrient sorption of an Arenosol in semi-arid NE-Brazil

In the semi-arid Northeast of Brazil nutrient-poor Arenosol with a low capacity to retain water and nutrients is the predominant soil type. Our aim is to provide a long-term melioration of the soils with locally available and inexpensive materials. We hypothesize an increase in nutrient sorption by the addition of biochar and clay. We conducted adsorption experiments according to OECD 106 batch equilibrium method in order to test this hypothesis. Sandy Arenosol, locally produced pyrolized biochar made of Prosopis juliflora, and a clayey Vertisol with a clay content of 69.8 %, all from our project area in Pernambuco, NE-Brazil, were used. The percentage of biochar and Vertisol added were 0 % (pure Arenosol), 1 %, 2.5 %, 5 %, 10 %, 100 % (pure biochar respectively Vertisol). Samples were shaken for 24 hours in a 1:5 solid-solution ratio in six different concentrations of Ammonium-N, Nitrate-N (0 - 25 mg L-1 each), Phosphorus (0 - 19.8 mg L-1) and Potassium (0 - 50 mg L-1). These concentrations were chosen to represent a common range of nutrients in a prevalent quaternary fertilization scheme of N:P:K of 1:0.4:1, with half NH4-N and NO3-N each. Then, where possible, sorption isotherms according to Langmuir were derived. Addition of biochar and Vertisol only showed marginal effects on Ammonium sorption. We detected a high loss of Ammonium with pure biochar, we assume loss of gaseous NH3. High rates of biochar addition caused Nitrate retention. Biochar increased P sorption with a maximum adsorption capacity (qmax) of 27.35 mg kg-1 for the 5 % amendment, although some P was leached out (up to 1.58 mg kg-1 for the 10 % addition). Phosphate sorption on Vertisol was even higher with a qmax for the 5 % addition of 60.77 mg kg-1. Potassium did not sorb to biochar, but was strongly leached out (84.19 mg kg-1 out of the 5 % addition). For Vertisol we observed a strong Potassium sorption that is linear within the concentration range we tested. A possible enhancement of nutrient

Sequence stratigraphic analysis of Cenomanian greenhouse palaeosols: A case study from southern Patagonia, Argentina

The aim of this contribution is to analyse extrinsic (i.e., tectonics, climate and eustasy) and intrinsic (i.e., palaeotopography, palaeodrainage and relative sedimentation rates) factors that controlled palaeosol development in the Cenomanian Mata Amarilla Formation (Austral foreland basin, southwestern Patagonia, Argentina). Detailed sedimentological logs, facies analysis, pedofeatures and palaeosol horizon identification led to the definition of six pedotypes, which represent Histosols, acid sulphate Histosols, Vertisols, hydromorphic Vertisols, Inceptisols and vertic Alfisols. Small- and large-scale changes in palaeosol development were recognised throughout the units. Small-scale or high-frequency variations, identified within the middle section are represented by the lateral and vertical superimposition of Inceptisols, Vertisols and hydromorphic Vertisols. Lateral changes are interpreted as the result of intrinsic factors to the depositional systems, such as the relative position within the floodplain and the distance from the main channels, that condition the nature of parent material, the sedimentation rate and eventually the palaeotopographic position. Vertical stacking of different soil types is linked to avulsion processes and the relatively abrupt change in the distance to main channels as the system aggraded. The large-scale or low-frequency vertical variations in palaeosol type occurring in the Mata Amarilla Formation are related to long-term changes in depositional environments. The lower and upper sections of the studied logs are characterised by Histosols and acid sulphate Histosols, and few hydromorphic Vertisols associated with low-gradient coastal environments (i.e., lagoons, estuaries and distal fluvial systems). At the lower boundary of the middle section, a thick palaeosol succession composed of vertic Alfisols occurs. The rest of the middle section is characterised by Vertisols, hydromorphic Vertisols and Inceptisols occurring on distal and

Land application of municipal sewage sludge and city compost as organic manures make it imperative to assess heavy-metal pollution in soils and crops. Greenhouse experiments, conducted on maize in a vertisol and an ultisol amended with various doses of dry sewage sludge and city compost from Mumbai, indicated significant increases in dry matter-yields only in the vertisol. Significantly higher concentrations of Zn, Cu, Co, Pb, Ni and Cd were obtained in plants grown in the amended ultisol, but not in the amended vertisol. As Cd is the most toxic, experiments were conducted with four contrasting soils amended with varying doses of Cd-enriched sewage sludge and city compost. Results showed significant reductions in dry-matter yields of maize shoots at the higher rates of sludge or compost in the ultisol and an alfisol, but with no significant effects in the vertisol or an entisol. The levels of Cd and Zn were significantly elevated in plants in all four soil types. There were negative residual effects from the sludge and compost amendments: dry-matter yields of a succeeding maize crop were decreased in the ultisol and alfisol. Experiments with soils amended with sludge enriched with either Cd or Zn at 80 mg kg -1 indicated significant reductions in dry matter in all soils with Cd, but not with Zn. The results demonstrate that sewage sludges and city composts may be effectively used for maximizing crop yields, especially in vertisols and entisols. However, caution has to be exercised when using sludges containing even relatively low levels of Cd, or high levels of Zn, depending upon soil type. (author)

Full Text Available The studied area is placed in North-East Jebel locality. Based on the physical and chemical characteristics and soil morphology profile, the following types of soil were identified: typical preluvosol, typical and gleyic eutricambosols, luvic solonet, gleysol, gleyic vertisol and gleyic-stagnic vertisol. The assessment of land quality (fertility was determined by bonitation. For the notes of bonitation calculation, the following ecopedological indicatories have been used: annual medium temperature, annual medium precipitations, depth of the underground water, texture in Ap horizon, gleization, pseudogleization, salinization, edafic volume, porosity, soil reaction (pH, humus reserve and content of CaCO3. The way that these indicators influence the notes of bonitation is different from a type of soil to another and the use of land. Thus, for grassland, typical preluvosol, the note of bonitate is 81 and it’s included in class II of quality (favorability, luvic solonet with 63 points in class IV of quality, typical eutricambosols with 58 points and vertisol with 57 points, in class V of quality, gleysol with 32 points and gleyic eutricambosol with 36 points, in class VII of quality. In case of using the land for growing maize, we have the following: typical preluvosol with 90 points which is in class II of quality, typical eutricambosol with 54 points and gleyic vertisol with 60 points, in class V of quality, luvic solonet with 49 points in class VI of quality, gleyic-stagnic vertisol with 35 points, in class VII of quality, gleysol with 24 points and gleyic eutricambosol with 29 points, in class VIII of quality. The notes of bonitation calculation, including them in the favorability classes, showed up that lands from Jebel area are good and very good quality, exception those that develop on gleysol and gleyic eutricambosols soils.

Full Text Available Se realizó un estudio de los suelos Vertisoles que son los más difundido en Cuba y donde se plantan la mayoría de los cultivos. Las investigaciones se desarrollaron en la UBPC "Walter Mulet" de la Empresa "Antonio Maceo" de Cacocum, provincia de Holguín, seleccionándose tres áreas de 1 hectárea: una en barbecho, otra sembrada de caña por más de 15 años y la última en proceso de reconversión para determinar la resistencia de penetración. Se utilizó el penetrómetro de impacto seleccionándose 16 puntos por hectárea y en cada uno se tomaron los datos a diferentes profundidades cada 10 cm hasta los 50 cm de profundidad; los resultados abordaron el alto grado de resistencia del área en barbecho y sembrada de caña, provocado por la ausencia de atenciones culturales, no siendo así en el área destinada a la reconversión. Para los análisis se utilizaron técnicas de agricultura de precisión y además se notó la presencia de carbonatos aproximadamente a los 30 centímetros de profundidad los que permitirán trazar estrategias tecnológicas para cada caso encaminadas al mejoramiento de los suelos.

Total Contents and Sequential Extraction of Heavy Metals in Soils Irrigated with Wastewater, Akaki, Ethiopia

Fitamo, Daniel; Itana, Fisseha; Olsson, Mats

2007-02-01

The Akaki River, laden with untreated wastes from domestic, industrial, and commercial sources, serves as a source of water for irrigating vegetable farms. The purpose of this study is to identify the impact of waste-water irrigation on the level of heavy metals and to predict their potential mobility and bioavailability. Zn and V had the highest, whereas Hg the lowest, concentrations observed in the soils. The average contents of As, Co, Cr, Cu, Ni, Zn, V, and Hg of both soils; and Pb and Se from Fluvisol surpassed the mean + 2 SD of the corresponding levels reported for their uncontaminated counterparts. Apparently, irrigation with waste water for the last few decades has contributed to the observed higher concentrations of the above elements in the study soils (Vertisol and Fluvisol) when compared to uncontaminated Vertisol and Fluvisol. On the other hand, Vertisol accommodated comparatively higher average levels of Cr, Cu, Ni, Zn, etc V, and Cd, whereas high contents of Pb and Se were observed in Fluvisol. Alternatively, comparable levels of Co and Hg were found in either soil. Except for Ni, Cr, and Cd in contaminated Vertisol, heavy metals in the soils were not significantly affected by the depth (0-20 and 30-50 cm). When the same element from the two soils was compared, the levels of Cr, Cu, Ni, Pb, Se, Zn, V, Cd at 0-20 cm; and Cr, Ni, Cu, Cd, and Zn at 30-50 cm were significantly different. Organic carbon (in both soils), CEC (Fluvisol), and clay (Vertisol) exhibited significant positive correspondences with the total heavy metal levels. Conversely, Se and Hg contents revealed perceptible associations with carbonate and pH. The exchangeable fraction was dominated by Hg and Cd, whereas the carbonate fraction was abounded with Cd, Pb, and Co. conversely, V and Pb displayed strong affinity to reducible fraction, where as Cr, Cu, Zn, and Ni dominated the oxidizable fraction. Cr, Hg, Se, and Zn (in both soils) showed preference to the residual fraction

Verdoodt, A.

2009-01-01

Full Text Available Five Vertisols and two Vertic Inceptisols developed from basalt and alluvial materials were characterized for physical and chemical properties. Correlative statistical relationships were established among physical and chemical properties including cation exchange capacity (CEC, percent total clay, electrical conductivity (EC, base saturation % (BS, pH-H2O, pH-KCl, CaCO3 equivalent, organic carbon (OC, total nitrogen (TN, P-Bray and P-Olsen. Correlative relationships were established among parameters for all horizons of the soils studied as well as among parameters within individual horizons. P-Olsen was highly correlated with OC and TN; simple coefficients of determination (r2 were 0.81 and 0.69, respectively. CaCO3 was highly correlated with pH-H2O and pH-KCl; r2 values were 0.68 and 0.60, respectively. Similar correlations were obtained for pHKCl vs pH-H2O and pH-KCl vs EC, with r2 values of 0.92 and 0.70, respectively. Total nitrogen was also very highly correlated with OC (r2= 0.88. Base saturation was highly correlated with pH-KCl and pH-H2O giving r2 values of 0.62 and 0.64, respectively. When correlative relationships were carried out among parameters within individual horizons very high correlation coefficients were obtained for OC vs TN (r= 0.98 - 1.00, OC vs P-Olsen (r= 0.96 - 0.99, BS vs pH-KCl (r= 0.82 - 1.00, BS vs pH-H2O (r= 0.86 - 1.00. Most of the simple correlation coefficients obtained for EC with pH-KCl and pH-H2O were > 0.81. High correlation coefficients (0.80 - 1.00 were obtained for % clay vs total CEC for most soils studied. Regression relationships developed constitute useful predictive indices for estimating agronomic properties from existing physical and chemical data and soil survey reports of the Bale Mountain area of Ethiopia. This study has demonstrated that statistical correlation can be used to cross-check the quality of analytical data both among horizons of different soil profiles and within individual soil

A greenhouse pot culture experiment was conducted to study the effect of graded levels of waste mica (0, 10, 20 and 40 g kg{sup -1}) on reducing the radiocesium uptake by spinach (Spinacia olerecea L) and lettuce (Lactuca sativa L.) grown in {sup 134}Cs-contaminated (at 37 k Bq kg{sup -1} soil) Inceptisols, Vertisols and Ultisols. The biomass yield, and potassium content and its uptake by crops have been significantly improved by waste mica application. The crops grown in Vertisols recorded higher biomass yield, and K content and its uptake as compared with Inceptisols and Ultisols. The average {sup 134}Cs transfer factor values recorded were: 0.21, 0.17 and 0.26 at the first cutting, 0.15, 0.12 and 0.28 at the second cutting and 0.07, 0.05 and 0.23 at the third cutting from Inceptisols, Vertisols and Ultisols, respectively. Waste mica significantly suppressed radiocesium uptake, the effect being more pronounced at 40 g mica kg{sup -1} soil. There exists an inverse relationship between the {sup 134}Cs transfer factors with plant potassium content and also the K uptake by the crops. (authors)

Influence of cracking clays on satellite estimated and model simulated soil moisture

Directory of Open Access Journals (Sweden)

Y. Y. Liu

2010-06-01

Full Text Available Vertisols are clay soils that are common in the monsoonal and dry warm regions of the world. One of the characteristics of these soil types is to form deep cracks during periods of extended dry, resulting in significant variation of the soil and hydrologic properties. Understanding the influence of these varying soil properties on the hydrological behavior of the system is of considerable interest, particularly in the retrieval or simulation of soil moisture. In this study we compare surface soil moisture (θ in m³ m⁻³ retrievals from AMSR-E using the VUA-NASA (Vrije Universiteit Amsterdam in collaboration with NASA algorithm with simulations from the Community Land Model (CLM over vertisol regions of mainland Australia. For the three-year period examined here (2003–2005, both products display reasonable agreement during wet periods. During dry periods however, AMSR-E retrieved near surface soil moisture falls below values for surrounding non-clay soils, while CLM simulations are higher. CLM θ are also higher than AMSR-E and their difference keeps increasing throughout these dry periods. To identify the possible causes for these discrepancies, the impacts of land use, topography, soil properties and surface temperature used in the AMSR-E algorithm, together with vegetation density and rainfall patterns, were investigated. However these do not explain the observed θ responses. Qualitative analysis of the retrieval model suggests that the most likely reason for the low AMSR-E θ is the increase in soil porosity and surface roughness resulting from cracking of the soil. To quantitatively identify the role of each factor, more in situ measurements of soil properties that can represent different stages of cracking need to be collected. CLM does not simulate the behavior of cracking soils, including the additional loss of moisture from the soil continuum during drying and the infiltration into cracks during rainfall events

Full Text Available Toxoplasma gondii is a protozoan parasite that infects up to a third of the world′s population. Infection is mainly acquired by ingestion of food that is contaminated with oocysts. We report an outbreak of ocular toxoplasmosis, which is an acute acquired type rather than reactivation of congenital toxoplasmosis. Our preliminary investigation points to municipal water contamination. This outbreak only proves the need of an effective public health system and health education in curtailing any outbreak.

Full Text Available Shallot is a high-economic value commodity, but so far the supply is still lower than the demand. One of the production problem is “moler” disease of shallot (MDS caused by Fusarium oxysporum f.sp. cepae (FOCe. The aim of this research was to study the potentiality of shallot rhizobacteria (SRB from various soil ordo to inhibit (MDS. This research was held in the Laboratory of Biology and Soil Health and Greenhouse at UNS. This research was carried out by exploring rhizobacteria of shallot planted on Entisols, Andisols, and Vertisols. Rhizobacteria exploration results were tested for their ability to control Fusarium oxysporum f.sp.cepae (FOCe. Inhibitory ability test of SRB to FOCe was carried out in vitro and on shallot in the greenhouse. The green house research used a Completely Randomized Design (CDR with two factors. The first factor was rhizobacteria combination and the second factor was various soil ordo (Andisols, Entisols, and Vertisols. Each treatment was replicated three times. It was obtained three rhizobacteria isolates from Vertisols (B15: 70%, Andisols (B12:45,55%, and Entisols (B10:46,67% being the highest inhibition results to FOCe. The combination of rhizobacteria B12 and B10 provided the lowest intensity.

Examining Local Climate Variability in the Late Pennsylvanian Through Paleosols: An Example from the Lower Conemaugh Group of Southeastern Ohio, USA

2012-11-01

Full Text Available Three temporally close stratigraphic sections were excavated in Glenshaw Formation of Athens County, Ohio. The described units are Upper Pennsylvanian (Gzhelian, 305–302 Ma and located in the distal portion of the Appalachian foreland basin. Mudstone units interpreted as paleosols were identified across all three sections. Detailed field and micromorphological studies lead to the recognition of two separate paleosols within the profile. The profile consists of a composite paleosol composed of two cumulative paleosols. The lower paleosol is interpreted as a calcic Vertisol which formed in a seasonally dry environment whereas the upper paleosol is interpreted as a gleyed Inceptisol which formed in a seasonally wet environment. The change in paleosol types is the result of increased precipitation which led to saturation of the soil and surface ponding. Pedogenic carbonate nodules are a common feature throughout the entire profile as are stress cutans. A coalesced carbonate horizon (Bk was observed approximate 120 cm from the top of the profile in all three sections. This carbonate horizon formed in the Vertisol and later served as a barrier which limited the downward movement of surface water. This limited the gleization of the bottom portion of the overprinted Vertisol resulting in a diffuse boundary with the overlying Inceptisol and producing a composite paleosol.

STUDY OF A SOIL WITH SWELLING AND SHRINKING PHENOMENA

Directory of Open Access Journals (Sweden)

G. Rogobete

2012-12-01

Full Text Available Vertisols are deep clayey soils, with more than 45 % clay, dominated by clay minerals, such as smectites, that expand upon wetting and shrink upon drying. The most important physical characteristics of Vertisols are a low hydraulic conductivity and stickiness when wet and high flow of water through the cracks when dry. They become very hard when dry and in all the time are difficult to work. During the rainy season, the cracks disappear and the soil becomes sticky and plastic with a very slippery surface which makes Vertisols in – trafficable when wet. Water movement in soil that change volume with water content is not well understood and management of swelling soil remains problematic. Swelling or shrinking result in vertical displacement of the wet soil, which involves gravitational work and contributes to an overburden component to the total potential of the soil water. Many swelling soil crack and the network of cracks provides pathways for rapid flow of water which prejudice application of theory based on Darcian flow. One – dimensional flow of water in a swelling system requires material balance equation for both the aqueous and solid phases. The analytical data offers some values particle – size distribution, compression, swelling degree and pressure, plasticity index, elastic modulus, triaxial shear, angle of shear and load carrying capacity in order to realize a foundation study for some constructions.

Evaluation of methods for available Zn in four soil orders in Costa Rica

International Nuclear Information System (INIS)

Molina, E.; Bornemisza, E.

2001-01-01

Analytical methods for available Zn determination were evaluated on four soil orders in Costa Rica (Ultisols, Vertisols, Inceptisols and Andisols) with 25 samples for each; using the following extract solutions : Modified Olsen, Mehlich 3, Modified Morgan , DTPA and HCI. The Zn levels obtained depended on the chemical characteristics of the extracting solutions. The highest levels were obtained with HCI, except for the Vertisols. The solutions with EDTA (Modified Olsen and Mehlich 3), extracted intermediate levels of Zn, while the method using DTPA (Modified Morgan and DTPA) gave the lowest Zn values . In most of the cases, significant values of correlation were obtained between the 5 extraction methods; so for individual soil orders, or comparing all 100 soils. The highest correlation coefficients for extractable Zn were found for the Mehlich 3, Modified Morgan and DTPA. The correlations were consistent for the 4 orders, which indicate that they are adaptable to different soils, a useful characteristic for these methods. The Modified Olsen was the most efficient extractor in slightly acis soils (Vertisols and Inceptisols). The HCI extracted very high Zn levels, which are probably not related to plant available forms. It is concluded that the Mehlich 3, Modified Morgan and DTPA solutions are probably adequate for available Zn determination and might present an alternative to substitute the generally used Modified Olsen solution in Costa Rica.

Adsorption-desorption and leaching of pyraclostrobin in Indian soils.

Science.gov (United States)

Reddy, S Navakishore; Gupta, Suman; Gajbhiye, Vijay T

2013-01-01

Pyraclostrobin is a new broad-spectrum foliar applied and seed protectant fungicide of the strobilurin group. In this paper, adsorption-desorption of pyraclostrobin has been investigated in three different soils viz. Inceptisol (sandy loam, Delhi), Vertisol (sandy clay, Hyderabad) and Ultisol (sandy clay loam, Thrissur). Effect of organic matter and clay content on sorption was also studied in Inceptisol of Delhi. Leaching potential of pyraclostrobin as influenced by rainfall was studied in intact soil columns to confirm the results of adsorption-desorption studies. The adsorption studies were carried out at initial concentrations of 0.05, 0.1, 0.5, 1 and 1.5 μg mL(-1). The distribution coefficient (Kd) values in three test soils ranged from 4.91 to 18.26 indicating moderate to high adsorption. Among the three test soils, adsorption was the highest in Ultisol (Kd 18.26), followed by Vertisol (Kd 9.87) and Inceptisol (Kd 4.91). KF value was also highest for Ultisol soil (66.21), followed by Vertisol (40.88) and Inceptisol (8.59). S-type adsorption isotherms were observed in all the three test soils. Kd values in organic carbon-removed soil and clay-removed soil were 3.57 and 2.83 respectively, indicating lower adsorption than normal Inceptisol. Desorption studies were carried out at initial concentrations of 0.5, 1 and 1.5 μg mL(-1). Desorption was the greatest in Inceptisol, followed by Vertisol and Ultisol. Amounts of pyraclostrobin desorbed in three desorption cycles for different concentrations were 23.1-25.3%, 9.4-20.7% and 8.1-13.6% in Inceptisol, Vertisol and Ultisol respectively. Desorption was higher in clay fraction-removed and organic carbonremoved soils than normal Inceptisol. Desorption was slower than adsorption in all the test soils, indicating hysteresis effect (with hysteresis coefficient values varying from 0.05 to 0.20). Low values of hysteresis coefficient suggest high hysteresis effect indicating easy and strong adsorption, and slow

Full Text Available The safety management is very important in the process of construction .The traditional methods of construction safety control cannot meet the construction of big project. To ensure the safety of construction and reduce accidents in the process of construction the current situation and problems we face in construction safety management should be studied first. And then the project risk warning mechanism based on the GIS is constructed according to the problems we faced to achieve visual monitoring and warning of construction safety risk management and to provide decision support for construction. This project aims to develop a web-based spatial decision support system model for proactive health and safety management in linear construction projects. 5 Currently health and safety management is usually performed reactively instead of proactive management since hazard identification and risk assessment is mostly performed on paper based documents that are not effectively used at site. An information system relates to a chain of operations lead to planning the observation and collection of data to storage and analysis of data to the use of derived information in decision-making processes. To create a web-based free and open sourced GIS that can work with different data formats by exchanging and presenting data as a real-time map on web.

Is vetiver grass of interest for the remediation of Cu and Cd to protect marketing gardens in Burkina Faso?

Science.gov (United States)

Ondo Zue Abaga, Norbert; Dousset, Sylvie; Mbengue, Saliou; Munier-Lamy, Colette

2014-10-01

In Burkina-Faso, urban vegetable agriculture is often characterized by urban solid waste fertilizer inputs containing heavy metals such as Cu and Cd. Thus, the relevance of surrounding urban vegetable plots with vetiver hedges to reduce environmental pollution by Cu and Cd was investigated by adsorption studies and pot experiments. Vetiver biomass, its metal contents and, its total and MgCl2 extractable soil metals were monitored over 6months in the presence of a mixture of metal at two concentrations: 2-10 and 100-500mgkg(-1), for Cd and Cu, respectively. The Freundlich adsorption coefficient (Kf) values increased after vetiver growth and were significantly higher for vertisol than for lixisol. After 6months, the vetiver that was grown on lixisol accumulated more metal, increasing up to 4635mgkg(-1) for Cu and to 21.8mgkg(-1) for Cd, than did the vetiver that was grown on vertisol, increasing up to 1534mgkg(-1) for Cu and to 7.2mgkg(-1) for Cd. The metal bioconcentration factor, which was significantly higher for Cd, increased with the applied concentration and ranged from 1.6 to 14 for Cu and from 2.3 to 22 for Cd. Additionally, the translocation factors were higher for Cd (0.38-7.3) than for Cu (0.07-2.6), and the translocation was easiest from lixisol than from vertisol. Thus our results demonstrate the ability of vetiver for Cu and Cd phytoremediation in Burkina Faso soils. Nevertheless, these results should be confirmed across the field to advocate the establishment of vetiver hedges. Copyright © 2014 Elsevier Ltd. All rights reserved.

Carbon stocks, greenhouse gas emissions and water balance of Sudanese savannah woodlands in relation to climate change

Energy Technology Data Exchange (ETDEWEB)

Alam, S. A.

2013-06-01

Understanding the carbon (C) sequestration potential of drylands requires knowledge of the stocks of C in soils and biomass and on the factors affecting them. The overall aim of the study was to determine and evaluate the variation in the C stocks and water balance of Acacia savannah woodlands across the dryland (arid and semi-arid) region (10-16 deg N; 21-36 deg E) of the former Sudan (now mainly in the Republic of the Sudan) and how they are related to climatic factors and may be affected by climate change. The role played by small but numerous brick making industries on woodland deforestation in the region and greenhouse gas production was also investigated. The study region is often referred to as the gum belt because it is the world's major source of gum Arabic, which is harvested from Acacia trees. The soils in the centre and west of the region are mainly Arenosols (sandy soils) and those in the eastern part are mainly Vertisols (clay soils). The soils are C poor and often in a degraded state. This dissertation consists of a summary section and four articles (Study I, II, III and IV). Study I focuses on fuelwood consumption by the brick making industries (BMIs) and associated deforestation and greenhouse gas (GHG) emissions. In Study II the C densities (g C m-2) of the woodland tree biomass and soil (1 m) for 39 map sheets covering the study region were determined from national forest inventory data and global soil databases and the dependence on mean annual precipitation (MAP) and mean annual temperature (MAT) determined. The water balance of savannah woodlands for the same 39 map sheets was modelled in Study III and the variation in water balance components across the region evaluated. The potential impacts of climate change on woodland biomass C density and water-use (actual evapotranspiration, AET) was analysed for eight of the map sheets in Study IV. Sudanese BMIs consume a considerable amount of fuelwood that mainly comes from unsustainably managed

Impact of conservation agriculture on harnessing sustainability and building resilience against land degradation in the northern Ethiopian highlands

Science.gov (United States)

Araya, Tesfay; Cornelis, Wim M.; Govaerts, Bram; Bauer, Hans; Deckers, Jozef; Nyssen, Jan

2013-04-01

Conservation Agriculture (CA) aims at improving soil quality and crop yield whilst reducing runoff and topsoil erosion which raises the soil resilience to combat soil degradation. Different chemical, physical, and biological properties of a soil interact in complex ways that determine the crop productivity potential of the soil. Hence, a medium-term tillage experiment was carried out (2005 to 2011) on a Vertisol to evaluate changes in soil quality, runoff and soil loss due to CA-based field conservation practices in northern Ethiopia. The experimental layout was implemented in a randomized complete block design with three replications on permanent plots of 5 m by 19 m. The tillage treatments were derdero+ (DER+) with a furrow and permanent raised bed planting system, plowed once at planting by refreshing the furrow and with 30% standing crop residue retention, terwah+ (TER+) with plowing once at planting with 30% standing crop residue retention and contour furrows made at 1.5 m distance interval, and conventional tillage (CT) with a minimum of three tillage operations and removal of crop residues. All the plowing and reshaping of the furrows was done using the local ard plow mahresha. Local crop rotation practices followed during the seven years sequentially from the first to the seventh year included wheat-teff-wheat-barley-wheat-teff-grass pea. Glyphosate was sprayed starting from the third year (2007) at 2 l ha-1 before planting to control pre-emergent weed in DER+ and TER+. Significantly different (pindex, consistency index, cone index, air capacity and macroporosity were shown to significantly increase in soils subjected to DER+ planting system compared to CT, specifically at 0-10 cm depth. Aggregate instability index, crack size at harvest, relative water capacity and plastic limit were significantly larger in CT compared to CA treatments.

Soil moisture distribution usually presents extreme variation at multiple spatial scales. Image analysis could be a useful tool for investigating these spatial patterns of apparent soil moisture at multiple resolutions. The objectives of the present work were (i) to describe the local scaling of apparent soil moisture distribution and (ii) to define apparent soil moisture patterns from vertical planes of Vertisol pit images. Two soil pits (0.70 m long × 0.60 m width × 0.30 m depth) were excavated on a bare Mazic Pellic Vertisol. One was excavated in April/2011 and the other pit was established in May/2011 after 3 days of a moderate rainfall event. Digital photographs were taken from each Vertisol pit using a Kodak™ digital camera. The mean image size was 1600 × 945 pixels with one physical pixel ≈373 μm of the photographed soil pit. For more details see Cumbrera et al. (2012). Geochemical exploration have found with increasingly interests and benefits of using fractal (power-law) models to characterize geochemical distribution, using the concentration-area (C-A) model (Cheng et al., 1994; Cheng, 2012). This method is based on the singularity maps of a measure that at each point define areas with self-similar properties that are shown in power-law relationships in Concentration-Area plots (C-A method). The C-A method together with the singularity map ("Singularity-CA" method) define thresholds that can be applied to segment the map. We have applied it to each soil image. The results show that, in spite of some computational and practical limitations, image analysis of apparent soil moisture patterns could be used to study the dynamical change of soil moisture sampling in agreement with previous results (Millán et al., 2016).

Full Text Available The paper tries to determine the environmental amplitude as well as the optimal conditions for the vegetation of Papaver rhoeas in the agrocoenoses of the Roztocze National Park's buffer zone, as compared to other Polish regions. The analysis is based on certain habitat and anthropogenic factors. Based on the author's own research and the data quoted in the literature, it has been found that Papaver rhoeas occurs in the associations and communities of the Caucalidion and Aperion alliances accompanying cereal and rape crops as well as in the Polygono-Chenopodion and Panico-Setarion alliances accompanying root crops. Papaver rhoeas demonstrates a large environmental scale, as its presence has been noted in low- and highlands, in foothills, in river valleys as well as on slopes. Moreover, it teams up with various types of soils (of a wide range of acidity, moisture as well as trophic and thermal conditions and complexes. Papaver rhoeas occurs most often and in the largest numbers in winter crops in the Lathyro-Melandrietum and Caucalidio-Scandicetum association which belongs to the Caucalidion alliance and in the Consolido-Brometum, Vicietum tetraspermae papaveretosum and V. t. consolidetosum association from the Aperion alliance. As far as root crops are considered, Papaver rhoeas shows up in the Lamio-Veronicetum politae association from the Polygono- Chenopodion alliance. It prefers chalky and Jurassic rendzinas containing CaCO3 and other fertile loam and loess soils which belong to wheat complexes, with their pH ranging from slightly acid to alkaline (Eutric Vertisols, chernozem, brown soil, alluvial soil and which are moderately moist, warm, medium-rich in nitrogen and with good soil biological activity. In the foothill areas, it dominates on alluvial soils in the river valleys; rarely has it been spotted on the slopes. Papaver rhoeas rarely occurs on the lightest sandy soils of the weak and very weak rye complexes and weak cereal

Two Australian soils, a vertisol (pH 6.8, 0.299% N) and a sandy yellow podzol (pH 6.2, 0.042% N), were used with digitgrass, Digitaria sp. X46-2 (PI 421785), in a growth room experiment. Comparisons were made between plants inoculated with live and autoclaved bacterial suspensions of Australian and Brazilian isolates of Azospirillum brasilense. Seedlings were inoculated on days 10 and 35. Acetylene-reducing activity was measured five times during the experiment. Dry matter yields of the digitgrass on the podzol (low N) inoculated with liver bacteria were 23% higher than those of the controls. On the vertisol (high N), yield increases from inoculation with live bacteria were 8.5%. The higher-yielding plants had significantly lower precent nitrogen, but when total nitrogen of the tops was calculated, the inoculated plants had a higher total N than did the controls (P = 0.04). Acetylene-reducing activity was variable in the experiment, ranging from 0.5 to 11.9 mu mol of C2H2 core -1 day -1. Live bacterial treatment induced a proliferation of roots, possible earlier maturity, higher percent dry matter, and a higher total N in the tops. (Refs. 21).

Gully erosion is an important environmental and food security challenge facing the world. Despite the immense damages resulting from gully erosion, comprehensive studies on the processes of gully formation and its management strategies are limited. This is especially true for valley-bottom gullies, which form under different conditions and are caused by different processes than hillslope gullies. A recent review on valley-bottom gully erosion causes and controlling factors identified that gully geomorphological processes, particularly related to gully bank retreat, governed gully occurrence and reclamations. However, most valley-bottom gully erosion studies do not consider gully bank stability and how it is impacted by soil hydrology and soil intrinsic properties. The aim is to analyze these impacts on gully bank retreat in the Koga river watershed, Ethiopia, for Nitisol and Vertisols, using field and numerical modeling approaches. Field observations showed gully network in Vertisols were greater than those in Nitisols. On the other hand, Nitisol gullies are wider and deeper than Vertisols. Monitoring of hydro-meteorological and soil data was started in June 2017 and will continue until the end of the 2017 rainy season (September) and for 2018 rainy periods as well. Thirty-six piezometers were installed at 4m average depth covering an area of 20 km2 near the gully reaches. Ground anchors were used to measure soil swelling and shrinkage. Soil moisture content and potential were measured using GS1 Soil Moisture sensors and MPS-6 Water Potential sensors. Gully bank soil physicochemical and engineering properties have been sampled and analyzed. Preliminary results from the early portion of the rainy season showed that most piezometers were already filled up with water. However, relatively deep (2m) water tables were recorded in piezometers located near the gully banks. The soil matric potential dropped from the onset of the rainy season (-6800 kPa ) towards the middle

Bacillus subtilis, an endophytic bacteria that lives inside the plant system is viewed as a potential source of novel genes with antimicrobial activity. B. subtilis strain Bs5 isolated from noni was found to be antagonistic to root knot nematode, Meloidogyne incognitainvitro. The endophytic nature of the bacteria was ascertained by labeling the bacteria with radioactive 32 P and introduced in to the plant system. Autoradiograph of young noni seedlings was developed 28 days after exposure period in the X-ray film. The work was carried out in the Radioisotope Laboratory, Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore. Autoradiography indicated a difference in intensity of darkening of photographic emulsion. A closer scrutiny of the autoradiograph showed intensity of the film darkening to be accentuated in the top leaves. It revealed that the radio labelled bacteria effectively translocated from root to shoot and colonized the stem, mid ribs and actively growing regions. From the study it becomes evident that the radio labelling and tracer analysis is an effective tool for tracking the movement and colonization of endophytic bacteria which are potential candidates for combating plant pathogens including plant parasitic nematodes.

The composition and structure of aggregates from different agrogenic soils in the southern steppe zone of European Russia have been studied. It is shown that the multi-level study (from the macro- to microlevel) of these horizons makes it possible to identify soil compaction caused by different elementary soil processes: solonetz-forming, vertisol-forming, and mechanical (wheel) compaction in the rainfed and irrigated soils. The understanding of the genesis of the compaction of soil horizons (natural or anthropogenic) is important for the economic evaluation of soil degradation. It should enable us to make more exact predictions of the rates of degradation processes and undertake adequate mitigation measures. The combined tomographic and micromorphological studies of aggregates of 1-2 and 3-5 mm in diameter from compacted horizons of different soils have been performed for the first time. Additional diagnostic features of negative solonetz- forming processes (low open porosity of aggregates seen on tomograms and filling of a considerable part of the intraped pores with mobile substance) and the vertisol-forming processes (large amount of fine intraaggregate pores seen on tomograms and a virtual absence of humus-clay plasma in the intraped zone)—have been identified. It is shown that the combination of microtomographic and micromorphological methods is helpful for studying the pore space of compacted horizons in cultivated soils.

Geology and climatic indicators in the Westphalian A New Glasgow formation, Nova Scotia, Canada: implications for the genesis of coal and of sandstone-hosted lead deposits

Chandler, F.W. [Geological Survey of Canada, Ottawa, ON (Canada)

1998-03-01

Disagreement exists on whether the early Pennsylvanian climate of the Euramerican coal province was everwet or seasonal. Abundant paleopedological evidence, including calcrete-bearing vertisols, shows that during formation of Westphalian C to Stephanian coals in Nova Scotia, the climate was tropical and seasonal with a pronounced by dry season; but interpretation of Westphalian A-B coal-bearing sequences lacks this form of evidence. Development of calcrete-bearing vertisols in alluvial fan deposits of the Westphalian A New Glasgow formation indicate that a tropical climate with a pronounced dry season was already in force by early Westphalian time. During the dry season, the coal swamps of the early Westphalian Joggins and Springhill Mines formations were fed by groundwater from coeval alluvial fan deposits of the Polly Brook Formation at the basin margin. Sedimentological evidence indicates that, similarly, groundwater flowed northward from the toe of the New Glasgow alluvial fan, but correlative palustrine sediments have not been found on land in the New Glasgow area. The possibility remains of an early Westphalian coalfield associated with the New Glasgow formation to the north under the Northumberland Strait and Gulf of St. Lawrence. Formation of the Yava sandstone-hosted lead deposit in the fluvial Silver Mine Formation of Cape Breton Island, a stratigraphic equivalent of the Cumberland Basin coal swamps, indicates that such deposits can form in fluvial strata deposited under a tropical seasonal climate with a pronounced dry season.

Full Text Available Cotton seed based artificial diet has been standardized for continuous rearing of pink bollworm Pectinophora gossypiella (Saunders at the Central Institute for Cotton Research, Regional Station, Coimbatore. The ingredients of the diet are easily available and are cost effective. Basic ingredients of the diet are cotton seed flour (processed and chick pea flour, Carbohydrate, Protein, Fat sources, multi vitamin, antimicrobial agents and agar as thickening agent are used as other ingredients. Micro centrifuge tubes with lid were used as rearing containers. Individual neonate larvae were released on each piece of the diet inside the micro centrifuge tube and the lids were closed. This prevented larval escape, retaining them inside the tubes and also prevented diet dehydration. The recovery of insect reared on diet was recorded as 95.56%. Egg hatchability and adult emergence were 100% while pupal malformation was nil. Eggs, larval and pupal periods were recorded as 4.8 ± 0.632, 25.10 ± 0.994 and 7.9 ± 0.88 days, respectively. Larval and pupal weights were recorded as 21.40 mg ± 3.63, 18.00 mg ± 2.73, respectively.

Rice tungro disease, one of the major constraints to rice production in South and Southeast Asia, is caused by a combination of two viruses: Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus (RTBV). The present study was undertaken to determine the genetic variation of RTSV population present in tungro endemic states of Indian subcontinent. Phylogenetic analysis based on coat protein sequences showed distinct divergence of Indian RTSV isolates into two groups; one consisted isolates from Hyderabad (Andhra Pradesh), Cuttack (Orissa), and Puducherry and another from West Bengal, Coimbatore (Tamil Nadu), and Kanyakumari (Tamil Nadu). The results obtained from phylogenetic study were further supported with the SNPs (single nucleotide polymorphism), INDELs (insertion and deletion) and evolutionary distance analysis. In addition, sequence difference count matrix revealed 2-68 nucleotides differences among all the Indian RTSV isolates taken in this study. However, at the protein level these differences were not significant as revealed by Ka/Ks ratio calculation. Sequence identity at nucleotide and amino acid level was 92-100% and 97-100%, respectively, among Indian isolates of RTSV. Understanding of the population structure of RTSV from tungro endemic regions of India would potentially provide insights into the molecular diversification of this virus.

Cracking up (and down): Linking multi-domain hydraulic properties with multi-scale hydrological processes in shrink-swell soils

Science.gov (United States)

Stewart, R. D.; Rupp, D. E.; Abou Najm, M. R.; Selker, J. S.

2017-12-01

Shrink-swell soils, often classified as Vertisols or vertic intergrades, are found on every continent except Antarctica and within many agricultural and urban regions. These soils are characterized by cyclical shrinking and swelling, in which bulk density and porosity distributions vary as functions of time and soil moisture. Crack networks that form in these soils act as dominant environmental controls on the movement of water, contaminants, and gases, making it important to develop fundamental understanding and tractable models of their hydrologic characteristics and behaviors. In this study, which took place primarily in the Secano Interior region of South-Central Chile, we quantified soil-water interactions across scales using a diverse and innovative dataset. These measurements were then utilized to develop a set of parsimonious multi-domain models for describing hydraulic properties and hydrological processes in shrink-swell soils. In a series of examples, we show how this model can predict porosity distributions, crack widths, saturated hydraulic conductivities, and surface runoff (i.e., overland flow) thresholds, by capturing the dominant mechanisms by which water moves through and interacts with clayey soils. Altogether, these models successfully link small-scale shrinkage/swelling behaviors with large-scale thresholds, and can be applied to describe important processes such as infiltration, overland flow development, and the preferential flow and transport of fluids and gases.

A pot experiment was conducted using labelled super-phosphate to study the utilization of fertilizer phosphorus by three paddy varieties, viz, Jaya, Ratna and Sona. Total P uptake and P derived from fertilizer, increased significantly with increasing levels of P applied (0 to 90 kg P 2 O 5 /ha), while the percent utilization of applied P showed a reverse trend. Straw and grain yield, in general, increased significantly with increasing P levels in all the three varieties. Average soil P uptake in grain and straw decreased with increasing levels of applied phosphorus. (author)

In Morocco, rainfed agriculture is practiced in the majority of agricultural land. However, the intensive land use coupled to the irregular rainfall constitutes a serious threat that affect country's food security. Conservation agriculture (CA) represents a promising alternative to produce more and sustainably. In fact, the direct seeding showed high yield in arid regions of Morocco but its extending to other more humid agro-ecological zones (rainfall > 350mm) remains scarce. In order to promote CA in Morocco, differents trials have been installed in central plateau of Morocco, to compare CA to conventional tillage (CT). The yields of the main practiced crops (wheat, lentil and checkpea) under CA and CT were analyzed and compared in the 3 soils types (Vertisol, Cambisol and Calcisol). Also, we studied the effect of CA on soil organic matter (SOM) and soil losses (SL) in the 3 different sites. The APSIM model was used to model the long term impact of CA compared to CT. The results obtained in this research have shown favorable effects of CA on crop production, SOM and soil erosion. Key words: Conservation agriculture, yield, soil properties, modeling, APSIM, Morocco.

Efficiency of 32 P labelled ammonium nitrate phosphate (ANP) containding 30, 50 and 90 per cent of water-soluble phosphorus (WSP) vis-a-vis that of entirely water soluble monoammonium orthophosphate (MAP) for wheat and succeeding maize crop on deep black (vertisol), calcareous black (vertisol), alluvial-Tarai (mollisol) and grey brown alluvial (aridisol) soils was examined in greenhouse experiments. Data on wheat indicated that ANP (50 per cent WSP) was, in general, equally efficient to MAP and ANP (90 per cent WSP) in terms of drymatter yield and total uptake of phosphorus in all soils examined, however, the per cent utilization of applied fertilizer was significantly higher for MAP and ANP (90 per cent WSP) than those for ANP (50 per cent WSP) in all soils. In general, ANP (30 per cent WSP) was significantly inferior to MAP and ANP (90 per cent WSP) in all soils. Data on the succeeding maize crop grown to flowering indicated that residual value of ANP (30 per cent WSP) was equal to that of MAP and ANP (90 per cent WSP) in terms of drymatter yield and phosphorus uptake by the four soils examined. Complementary incubation studies conducted upto 60 days on the above four soils at field capacity moisture status indicated highest 0.5 M NaHCO 3 (pH 8.5) extractable phosphorus levels in MAP treatments followed by ANP (50 per cent WSP) and least in ANP (30 per cent WSP) treatments.

Full Text Available The most abundant archaeological record in the middle and late Holocene in the litoral region of Uruguay is formed by ceramic materials. Previous information usually comes from macroscopic studies, oriented to the reconstruction of decorative styles, forms, and technology. This paper presents XRD analyses of archaeological ceramics from Guayacas site (Department of Paysandú . This study seeks to complement the knowledge about the first stage of the process of manufacture: the selection of raw materials. In order to do this, an XRD analysis is also carried out on sediments and outcrops in the area, as well as on sediments from an archaeological excavation. Results indicate that the paste of ceramic materials is uniform and lacks illite-like minerals. The anthropogenic soils present smectite, quartz, illite and mixed clays; the natural soils and outcrops are dominated by smectite and quartz. One of these soils is proposed as a potential source of local raw material. The data obtained provide new information for the understanding of the area of occupation on the Daymán river during the late Holocene

Webb, D.F.

1981-01-01

Observational aspects of the transition region and coronal structures of the solar active region are reviewed with an emphasis on imaging of the plasma loops which act as tracers of the magnetic flux loops. The study of the basic structure of an active region is discussed in terms of the morphological and thermal classifications of active region loops, including umbral structures, and observational knowledge of the thermal structure of loops is considered in relation to scaling laws, emission measures and the structures of individual loops. The temporal evolution of active region loop structures is reviewed with emphasis on ephemeral regions and the emergence of active regions. Planned future spaceborne observations of active region loop structures in the EUV and soft X-ray regions are also indicated

Thinking regionally: narrative, the medical humanities and region.

Science.gov (United States)

Waddington, Keir

2015-06-01

Drawing on multiple literatures from history, geography, anthropology, sociology and literature, this essay asks questions about what we mean by region and why narratives of region should matter to the medical humanities. The essay surveys how region can be used as a lens of analysis, exploring the various academic approaches to region and their limitations. It argues that regions are dynamic but also unstable as a category of analysis and are often used uncritically by scholars. In encouraging scholars working in the medical humanities to be aware that regions are not simple objective or analytical boxes, the essay shows how an awareness of region helps challenge metropolitan whiggism and ideas of core and periphery to give a more prominent place to hinterlands, market towns and rural environments. Furthermore, the essay considers how incorporating region into our understanding of illness can offer new insights. It demonstrates the need for scholars to be attuned to the narratives constructed around regions, suggesting that regions can be viewed as discursive formations that provide a frame for understanding both collective and personal ideas of, and responses to, health and illness, disease and healing, to create what Megan Davies calls a more nuanced 'intellectual cartography'.

Lukiwati, D. R.; Pujaningsih, R. I.; Murwani, R.

2018-02-01

The experiment aimed to evaluate the effect of some manure enriched with phosphorus (P) and nitrogen (N) organic (‘manure plus’) on crude protein and mineral production of sweet corn (Zea mays saccharata)and quality of fermented stover as livestock feed. A field experiment was conducted on a vertisol soil (low pH, nitrogen and low available Bray II extractable P). Randomized block design with 9 treatments in 3 replicates was used in this experiment. The treatments were T1(TSP), T2 (SA), T3 (TSP+SA), T4 (manure), T5 (manure+PR), T6 (manure+guano), T7 (manure+N-legume), T8 (manure+PR+N-legume), T9 (manure +guano+N-legume). Data were analyzed using analysis of variance (ANOVA) and the differences between treatment means were examined by Duncan Multiple Range Test (DMRT). Results of the experiment showed that the treatment significantly affected to the crude protein and calcium production of stover and nutrient concentration of fermented stover, but it is not affected to P production of stover. The result of DMRT showed that the effect of ‘manure plus’ was not significantly different on CP and Ca production of stover, mineral concentration, in vitro DMD and OMD of fermented stover, compared to inorganic fertilization. Conclusion, manure enriched with organic NP, resulted in similar on CP and Ca production of stover and nutrient concentration of fermented stover compared to inorganic fertilizer. Thus, organic-NP enriched manure could be an alternative and viable technology to utilize low grade of phosphate rock, guano and Gliricidea sepium to produce sweet corn in vertisol soil.

Glyphosate (N-phosphonomethyl-glycine), the active ingredient in several herbicide formulations, is a non-selective, post-emergent herbicide used in a variety of crop and non-crop situations. Glyphosate is a non-volatile herbicide that is relatively immobile in soil. Its degradation is due to microbiological processes and most laboratory studies have been conducted with 14C-glyphosate with the rate of 14CO2 evolution being used as an indication of herbicide breakdown. In this paper we have studied the glyphosate degradation in compost amendment soils using Scientilator Liquid TRIATHLER and Glyphosate-phosphonomethyl-14C-labeled with specific activity 2,2mCi/mmol. Four types of soils have been taken under study: Black Chernozem, Vertisol, Gleysol and Phaeozem with different characteristics. For the each type of soil have been realized four experimental variants (glyphosate blind sample with 1,5 ppm, concentration, autoclaved soil, soil with glyphosate and addition of compost in field concentration of 40 t/ha, respectively 60 t/ha. The mineralization curves of 14CO2 accumulated were compared during of 40 days. All the mineralization curves for the soils exhibited same patterns, with only two phases, the initial rapid phase of degradation, for about 20 days, attributed to microbial action on the free glyphosate and the second slow phase, when the curves attained plateaus. Compost applied with different concentrations to Vertisol and Black Chernozem did not appear to stimulate the microbial degradation of glyphosate. In Gleysol and Phaeozem with lower humus content, the mineralization curve of 14C indicate the increase degradation capacity, expressed as accumulated 14CO2 as % total 14C, with the increase of compost concentration.

Full Text Available This study investigates the spatial economic structure and inequality in Thailand at the national and regional levels, with a particular focus on the Northeastern region in the period from 1987 to 2007. The study has three main points: 1 examination of the economic structure and inequality at the national level and in the Northeastern region according to the Theil index, 2 determination of regional growth centres and satellite towns by using growth pole theory as a conceptual framework and incorporating spatial interaction analysis and 3 analysis of the relationship between regional growth centres and satellite towns with regard to the impact on growth and inequality. The results show that the Northeastern region is definitely the lagging region in the nation, by both gross domestic product (GDP and gross regional product (GRP per capita. It was therefore selected for a case study. Spatial analysis identified Nakhon Ratchasima, Khon Kaen, Udon Thani and Ubon Ratchathani as regional growth centres. Each of them has its own sphere of influence (or satellite towns, and the total area of regional growth centres and satellite towns are classified as sub-regions. The development of regional growth centres has a direct impact on sub-regional economic growth through economic and social relationships: urbanisation, industrial development, per capita growth, the number of higher educational institutes and so on. However, such growth negatively correlates with economic equality among the provinces in a sub-region. The inequality trend is obviously on an upswing. This study suggests that industrial links between regional growth centres and their satellite towns should be improved in order for regional growth centre development to have a consistently desirable effect on both economic growth and equality. Such a strong process means that the growth of regional growth centres will spread, leading to the development of their surrounding areas.

Full Text Available The paper analyzes findings yielded by the empirical study performed in the framework of an RGNF grant entitled “Image of a region as a communicative strategy for the authorities and mass media”. The methods of study included expert survey and formal survey (N=1000, July-September 2013, studying the opinion of respondents who were either internal experts residing in the Volgograd region (N=20; May-September 2013 or external experts who reside outside the region but maintain stable ties with the representatives of state and municipal authorities, regional mass media and business. The findings indicate that the Volgograd region has fallen behind other modernized Russian regions, that young people tend to leave it, that a negative image of the region as a declining territory persists. Answers to the open question “What is unacceptable for you in the existing image of the Volgograd region?” revealed major problems determining the local context of a declining region, and those were issues associated with inefficient regional/municipal administration: “the condition of the roads”, “constant replacement of people in the administration”, “politics as a whole”, “a destitute region without a good manager”, “unemployment”, “countryside is dying off”, “indifference of the authorities”, “roads, housing and public utilities and the administration”, “the authorities are not responsible for the people”, “the authorities do not solve the problems of the city or its people”, “thieving”, “dishonest authorities”, “the region goes to rack and ruin, no kindergartens or jobs”, “one cannot even walk in the streets”, “corruption”, “a stagnant region with low pay”, “no perspectives in the future”, “the region is stagnating due to corruption among officials”. According to the local Census Bureau, the Volgograd region can be classified as a declining territory where the population decline

Full Text Available OBJECTIVE To analyze the regional governance of the health systemin relation to management strategies and disputes. METHODOLOGICAL PROCEDURES A qualitative study with health managers from 19 municipalities in the health region of Bahia, Northeastern Brazil. Data were drawn from 17 semi-structured interviews of state, regional, and municipal health policymakers and managers; a focus group; observations of the regional interagency committee; and documents in 2012. The political-institutional and the organizational components were analyzed in the light of dialectical hermeneutics. RESULTS The regional interagency committee is the chief regional governance strategy/component and functions as a strategic tool for strengthening governance. It brings together a diversity of members responsible for decision making in the healthcare territories, who need to negotiate the allocation of funding and the distribution of facilities for common use in the region. The high turnover of health secretaries, their lack of autonomy from the local executive decisions, inadequate technical training to exercise their function, and the influence of party politics on decision making stand as obstacles to the regional interagency committee’s permeability to social demands. Funding is insufficient to enable the fulfillment of the officially integrated agreed-upon program or to boost public supply by the system, requiring that public managers procure services from the private market at values higher than the national health service price schedule (Brazilian Unified Health System Table. The study determined that “facilitators” under contract to health departments accelerated access to specialized (diagnostic, therapeutic and/or surgical services in other municipalities by direct payment to physicians for procedure costs already covered by the Brazilian Unified Health System.

Climate change is a global phenomenon with especially harsh effects on the Arctic and northern regions. The Arctic's average temperature has risen at almost twice the rate as elsewhere in the past few decades. Since 1966, the Arctic land area covered by snow in early summer has shrunk by almost a fifth. The Barents Region consists of the northern parts of Norway, Sweden, Finland and Russia (i.e. the European part of Russia). Climate change will cause serious impacts in the Barents Region because of its higher density of population living under harsh climatic conditions, thus setting it apart from other Arctic areas. In many cases, economic activities, like tourism, rely on certain weather conditions. For this reason, climate change and adaptation to it is of special urgency for the region. Regional climate change strategies are important tools for addressing mitigation and adaptation to climate change as they can be used to consolidate the efforts of different stakeholders of the public and private sectors. Regional strategies can be important factors in achieving the national and international goals. The study evaluated how the national climate change goals were implemented in the regional and local strategies and programmes in northern Finland. The specific goal was to describe the processes by which the regional strategies were prepared and implemented, and how the work was expanded to include the whole of northern Finland. Finally, the Finnish preparatory processes were compared to case examples of processes for preparing climate change strategies elsewhere in the Barents Region. This analysis provides examples of good practices in preparing a climate change strategy and implementing it. (orig.)

The development of the substorm-associated current system in the near-tail region is examined in the light of both experiment and theory. First, the March 28, 1979, event is examined intensively by using ground magnetometer data and satellite magnetic field and energetic particle data. The comparison of field-aligned current signatures at geosynchronous altitude and in the near-tail region indicates that the development of the region 1 system is not merely the enhancement in current intensity of the pre-existing system. This finding is consistent with the so-called current wedge model, in which the tail current is converted into a pair of field-aligned currents with the region 1 polarity at substorm onsets. Detailed inspection, however, suggests that the region 2 system is as important as the region 1 system. Statistical properties of the azimuthal magnetic component at synchronous orbit indicate that the deviation during disturbed periods is larger than expected from the enhancement of the region 1 current. These individual and statistical studies suggest that the region 2 system tends to develop in the synchronous region and that the coupling between the region 1 and the region 2 systems is important. The current closure in the magnetosphere is discussed from a viewpoint of the macroscopic behavior of plasma. It is suggested that the dawnside and the duskside region 2 currents are closed in the magnetosphere by the curvature current during the growth phase and by the magnetic gradient current during the expansion phase. The field-aligned currents of the region 1 and the region 2 systems are closed in the ionosphere by the Pedersen current. Consequently, the energy is dissipated as the Joule heating and this energy must be supplied from the magnetosphere. Therefore, the counter part of the Pedersen current, which closes the region 1 and the region 2 currents in magnetosphere, must be the dynamo current

The goal of this study is predicting human age using neuro-metrics derived from structural MRI, as well as investigating the relationships between age and predictive neuro-metrics. To this end, a cohort of healthy subjects were recruited from 1000 Functional Connectomes Project. The ages of the participations were ranging from 7 to 83 (36.17+/-20.46). The structural MRI for each subject was preprocessed using FreeSurfer, resulting in regional cortical thickness, mean curvature, regional volume and regional surface area for 148 anatomical parcellations. The individual age was predicted from the combination of regional and inter-regional neuro-metrics. The prediction accuracy is r = 0.835, p Pearson correlation coefficient between predicted ages and actual ages. Moreover, the LASSO linear regression also found certain predictive features, most of which were inter-regional features. The turning-point of the developmental trajectories in human brain was around 40 years old based on regional cortical thickness. In conclusion, structural MRI could be potential biomarkers for the aging in human brain. The human age could be successfully predicted from the combination of regional morphometry and inter-regional morphological similarity. The inter-regional measures could be beneficial to investigating human brain connectome.

None

1979-03-01

This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

Left ventricular regional ejection fractions were derived from background-corrected, time-activity curves in 43 patients assessed by both gated equilibrium radionuclide angiocardiography and left ventricular contrast angiography. From a single, modified left anterior oblique projection, the regional change in background corrected counts was determined in each of three anatomic regions. The normal range for regional radionuclide ejection fraction was determined in 10 patients with normal contrast ventriculograms and without obstructive coronary artery disease at coronary arteriography. Regional ejection fraction was compared with percent segmental axis shortening and extent of akinetic segments in corresponding regions of the contrast ventriculogram. Radionuclide and roentgenographic methods were in agreement as to the presence or absence of abnormal wall motion in 83 of 99 left ventricular regions (84%) in 33 patients evaluated prospectively. Comparison of regional ejection fraction demonstrated significant differences between regions with roentgenographically determined normokinesis hypokinesis, and akinesis. We conclude that the left ventricular regional ejection fraction provides a reliable quantitative assessment of regional left ventricular performance

Soil-crop simulator model is an effective tool for providing decision on agricultural management. APSIM (Agricultural Production Systems Simulator) was developed to simulate the biophysical process in farming system, and particularly in the economic and ecological features of the systems under climatic risk. The current literatures revealed that APSIM could be applied in wide zone, including temperate continental, temperate maritime, sub-tropic and arid climate, and Mediterranean climates, with the soil type of clay, duplex soil, vertisol, silt sandy, silt loam and silt clay loam. More than 20 crops have been simulated well. APSIM is powerful on describing crop structure, crop sequence, yield prediction, and quality control as well as erosion estimation under different planting pattern.

REGIONAL BLACK SEA ARCHITECTURE AND CONSEQUENCES FOR THE REGIONAL COOPERATION FRAMEWORK

Directory of Open Access Journals (Sweden)

Alina Homorozean

2010-12-01

Full Text Available Sometimes considered an asset, other times a liability, the Black Sea started recently to be regarded as a region. However, the Black Sea Region lacks a common vision, often due to the complicated and often inefficient nexus of regional cooperation initiatives. Following the logic of finding regional solutions for regional problems, this paper aims to assess existing institutional and regional initiatives, reflecting on the implications for the success of Black Sea regionalism in creating patterns of sustained and sustainable development and a high degree of actors' involvement.This paper concentrates on two complementary research questions: What is the regional order in the BSR and what does it imply for its future? What is the current contribution of the most significant cooperation initiatives and what are the consequences for regional institutionalism? For the purpose of this paper, I draw on best-practices from other two regions: the Northern Dimension and South- East Asia. Through a comparative perspective, I suggest an analysis of the most important initiatives: BSEC, CDC, Black Sea Synergy, Eastern Partnership, Baku Initiative and the BSF. This paper argues that a possible strategic solution for successful policy development lies in the creation of an integrated regional cooperation package, functioning on the principles of multi-speed and multi-dimensional cooperation in several policy fields, in a context in which the BSR seems to be caught between two paradigms: a European and a Russian-oriented one.

This paper deals with a precise description of the region of zitterbewegung below the Compton scale and the stochastic nature associated with it. We endeavor to delineate this particular region by means of Ito’s calculus and instigate certain features that are in sharp contrast with conventional physics. Interestingly, our work substantiates that the zitterbewegung region represents a pre-space-time region and from therein emerges the notion of our conventional space-time. Interestingly, this unique region engenders the relativistic and quantum mechanical aspects of space-time.

Recurrent Forbush decreases and relationship between active regions and M-regions

International Nuclear Information System (INIS)

Shah, G.N.; Kaul, C.L.; Razdan, H.; Bemalkhedkar, M.M.

1977-01-01

Recurrent Forbush decreases and recurrent geomagnetic disturbances have been attributed to the solar M-regions, which are sources of high velocity solar plasma streams. A study of recurrent Forbush decreases for the period 1966-75 has been made to examine any possible relationship of M-regions with solar active regions. It is shown that at the onset of the recurrent Forbush decrease at earth, there is a high probability of encountering a class of active regions at central meridian of the sun which give rise to flares of importance >= 28/3N. These active regions are found to be long-lasting and to have large areas as well as high Hsub(α)-intensities. Other active regions, producing flares of only lower importance, are distributed randomly on the sun with respect to the onset of a recurrent Forbush decrease. Using the quasiradial hypervelocity approximation, the base of the leading edge of the high velocity stream, at the onset of a recurrent Forbush decrease at earth, is traced to the solar longitude about 40 deg West of the central meridian. From these results, it is deduced that M-regions are located preferentially to the West of long-lasting, magnetically complex active regions. Earlier studies of the identification of the M-regions on the sun have been re-examined and shown to conform to this positional relationship. A possible mechanism of the development of an M-region to the West of the long-lasting magnetically complex active region is also discussed. (author)

Kadambarai: a boon for power availability and operations in Tamil Nadu

Energy Technology Data Exchange (ETDEWEB)

Arokiaswamy, N S.S.

1984-04-01

The Kadambarai pumped storage hydroelectric project located in the Annamali hills of the Coimbatore distict of India is described. The purpose of the project is to convert all of the available but unutilized power in the grid during low demand periods, e.g., between 10 pm and 6 am, into peaking power needed during the daytime. The water from the upper Aliyar Reservoir located below the power station is pumped into the Kadambarai dam. The water thus stored will run the same pump turbines generating peaking power neded to avoid load shedding and to run the pumpsets. The Kadambarai project is due to become operational with the commissioning of the first 100 MW machine in 1985. With the commissioning of the other 3 machines of 1987, the power station will become the largest single hydroelectric power station in the Tamil Nadu grid.

1993-01-01

In a field experiment, conducted with sunflower genotypes viz., Morden, APSH-11, and EC 68414 grown on a local black clay loam soil, fertilizer sulphur (labelled with 35 S) was applied at the rate of 0, 20, 40 and 60 kg S/ha through gypsum and ammonium sulphate. Among the sunflower genotypes, EC 68414 utilized maximum sulphur from the sources at any given growth stage i.e., star, bud, flowering and maturity. Sulphur applied through ammonium sulphate resulted in highest S utilization by all the genotypes at all the stages of growth. Though, sulphur uptake showed an increase, the S utilization decreased with increase in levels of S. The S uptake was highest at 60 kg S/ha level applied through any of the sources. The soil S uptake was higher than fertilizer S uptake at any given stage of crop. Maximum yields were recorded at 40 kg S/ha level signifying that this dose is optimum for sunflower grown on black clay loam soils. (author). 17 refs., 3 tabs

Cytogenetic analysis was performed on samples of Chironomus plumosus L. (Diptera, Chironomidae) taken from waterbodies of various types in Bryansk region (Russia) and Gomel region (Belarus). Karyotypes of specimens taken from stream pools of the Volga were used as reference samples. The populations of Bryansk and Gomel regions (except for a population of Lake Strativa in Starodubskii district, Bryansk region) exhibit broad structural variation, including somatic mosaicism for morphotypes of the salivary gland chromosome set, decondensation of telomeric sites, and the presence of small structural changes, as opposed to populations of Saratov region. As compared with Saratov and Bryansk regions, the Balbiani ring in the B-arm of chromosome I is repressed in populations of Gomel region. It is concluded that the chromosome set of Ch. plumosus in a range of waterbodies of Bryansk and Gomel regions is unstable.

An exploratory study on occurrence and impact of climate change on agriculture in Tamil Nadu, India

Varadan, R. Jayakumara; Kumar, Pramod; Jha, Girish Kumar; Pal, Suresh; Singh, Rashmi

2017-02-01

This study has been undertaken to examine the occurrence of climate change in Tamil Nadu, the southernmost state of India and its impact on rainfall pattern which is a primary constraint for agricultural production. Among the five sample stations examined across the state, the minimum temperature has increased significantly in Coimbatore while the same has decreased significantly in Vellore whereas both minimum and maximum temperatures have increased significantly in Madurai since 1969 with climate change occurring between late 1980s and early 1990s. As a result, the south-west monsoon has been disturbed with August rainfall increasing with more dispersion while September rainfall decreasing with less dispersion. Thus, September, the peak rainfall month of south-west monsoon before climate change, has become the monsoon receding month after climate change. Though there has been no change in the trend of the north-east monsoon, the quantity of October and November rainfall has considerably increased with increased dispersion after climate change. On the whole, south-west monsoon has decreased with decreased dispersion while north-east monsoon has increased with increased dispersion. Consequently, the season window for south-west monsoon crops has shortened while the north-east monsoon crops are left to fend against flood risk during their initial stages. Further, the incoherence in warming, climate change and rainfall impact seen across the state necessitates devising different indigenous and institutional adaptation strategies for different regions to overcome the adverse impacts of climate change on agriculture.

Revisiting regional flood frequency analysis in Slovakia: the region-of-influence method vs. traditional regional approaches

Science.gov (United States)

Gaál, Ladislav; Kohnová, Silvia; Szolgay, Ján.

2010-05-01

During the last 10-15 years, the Slovak hydrologists and water resources managers have been devoting considerable efforts to develop statistical tools for modelling probabilities of flood occurrence in a regional context. Initially, these models followed concepts to regional flood frequency analysis that were based on fixed regions, later the Hosking and Wallis's (HW; 1997) theory was adopted and modified. Nevertheless, it turned out to be that delineating homogeneous regions using these approaches is not a straightforward task, mostly due to the complex orography of the country. In this poster we aim at revisiting flood frequency analyses so far accomplished for Slovakia by adopting one of the pooling approaches, i.e. the region-of-influence (ROI) approach (Burn, 1990). In the ROI approach, unique pooling groups of similar sites are defined for each site under study. The similarity of sites is defined through Euclidean distance in the space of site attributes that had also proved applicability in former cluster analyses: catchment area, afforested area, hydrogeological catchment index and the mean annual precipitation. The homogeneity of the proposed pooling groups is evaluated by the built-in homogeneity test by Lu and Stedinger (1992). Two alternatives of the ROI approach are examined: in the first one the target size of the pooling groups is adjusted to the target return period T of the estimated flood quantiles, while in the other one, the target size is fixed, regardless of the target T. The statistical models of the ROI approach are inter-compared by the conventional regionalization approach based on the HW methodology where the parameters of flood frequency distributions were derived by means of L-moment statistics and a regional formula for the estimation of the index flood was derived by multiple regression methods using physiographic and climatic catchment characteristics. The inter-comparison of different frequency models is evaluated by means of the

A Means for the Scintigraphic Imaging of Regional Brain Dynamics. Regional Cerebral Blood Flow and Regional Cerebral Blood Volume

The use of freely diffusable inert radioactive gas as a washout indicator to measure regional cerebral blood flow has become a standardized kinetic procedure in many laboratories. Recent investigations with this technique have led us to conclude that we can reliably distinguish regional flow with perfusion against regional flow without perfusion from the early portion of the curve. Based on a detailed study of the early curve kinetics in patients with and without cerebral vascular disease we have defined the sampling duration necessary for application of the Anger gamma camera imaging process to regional changes in cerebral radioactivity. Using a standard camera and a small computer, a procedure has been developed and based upon entire field to determine the time of maximum height followed by analysis of the data in a matrix. This will permit a contour plot presentation of calculated regional cerebral blood flow in millilitres per 100 grams perfused brain per minute. In addition, we propose to augment this data by the display of regional non-perfusion blood flow versus regional cerebral flow with perfusion. Preliminary investigation on sampling duration, and Compton scattering were prerequisite to clinical scintigraphy of regional cerebral blood flow. In addition, the method of interface for the conventional Anger gamma camera to digital computers used in this procedure are discussed. Applications to further assess regional cerebral dynamics by scintigraphy are presented. (author)

PM10 aerosol samples collected from a sub-urban site in Coimbatore during pre-monsoon, monsoon, post-monsoon and winter from 2014 to 2016 showed a large variability from 7.6 to 89 μg m- 3 with an annual average of 41 ± 21 μg m- 3 (N = 69). High abundance of PM10 and other components were recorded during winter and lowest during monsoon period. Total carbonaceous aerosols and water soluble ionic species contributed to 31% and 45% of PM10 mass respectively. SO42 - was the most abundant species (average 9.8 ± 4.8 μg m- 3) and constituted for 24% of total mass. Organic Carbon (OC) was the next most abundant species ranging from 1 to 16 μg m- 3 with an average of 7 ± 3.6 μg m- 3 accounting for 17% of PM10 mass concentration. POC (primary organic carbon) and SOC (secondary organic carbon) accounted for 56% and 44% of OC respectively. A major portion of OC ( 60%) was found to be water soluble. The correlation between OC and EC (elemental carbon) was found to be higher for night-time compared to daytime suggesting their origin from common sources during night-time. K+ was found to be strongly correlated with OC during night-time. WSOC showed good correlation with POC and K+ which was high especially during night-time. WSON (water soluble organic nitrogen) accounted for 34% of water soluble total nitrogen (WSTN). HCO3- exhibited significant positive correlation with Ca2 + during daytime indicating their crustal origin. The observations suggest that the region is influenced by biomass burning sources, however during day-time, secondary production and terrestrial sources (due to high temperature and wind) significantly influence the atmospheric aerosols over this region.

Latin America Region: Between Dependence and Autonomy in Regional Processes

Directory of Open Access Journals (Sweden)

Wendy Vaca Hernández

2017-01-01

Full Text Available The space called Latin America has a particular history marked by centuries of colonialism and coloniality. The latter concept implies that the basic structure of the colonial system has not changed even though formal independence has been achieved. For this reason, the subcontinent has fluctuated between dependence and the quest for autonomy. These successive cycles have manifested themselves both in the internal configurations and in the regional schemes that have been undertaken. This paper analyzes the construction and evolution of the idea of a region: Latin America and the Caribbean. To that end it examines the concepts of region, regionalism, what Latin America and the Caribbean implies, and what are the transformations in these ideas that have emerged from the regional configurations of the Union of South American Nations (UNASUR and the Community of Latin American and Caribbean States (CELAC as plural organisms with broad objectives.

Recurrent forbush decreases and the relationship between active regions and M regions

International Nuclear Information System (INIS)

1978-01-01

Recurrent Forbush decreases and recurrent geomagnetic disturbances have been attributed to the solar M regions, which are sources of high-velocity solar plasma streams. A study of recurrent Forbush decreases for the period 1966--1975 has been made to examine any possible relationship of M regions with solar active regions. It is shown that at the onset of the recurrent Forbush decrease at the earth there is a high probability of encountering a class of active regions at the central meridian of the sun which give rise to flares of importance > or =2B/3N. These active regions are found to be long lasting and to have large areas as well as high Hα intensities. Other active regions, producing flares of lower importance, are distributed randomly on the sun with respect to the onset of a recurrent Forbush decrease. By using the quasi-radial hypervelocity approximation the base of the leading edge of the high-velocity stream at the onset of a recurrent Forbush decrease at the earth is traced to the solar longitude about 40 0 west of the central meridan. From these results it is deduced that M regions are located preferentially to the west of long-lasting magnetically complex active regions. Earlier studies of the identification of the M regions on the sun have been reexamined and shown to conform to this positional relationship. A possible mechanism of the development of an M region to the west of the long-lasting magnetically complex active region is also discussed

Body region dissatisfaction predicts attention to body regions on other women.

Lykins, Amy D; Ferris, Tamara; Graham, Cynthia A

2014-09-01

The proliferation of "idealized" (i.e., very thin and attractive) women in the media has contributed to increasing rates of body dissatisfaction among women. However, it remains relatively unknown how women attend to these images: does dissatisfaction predict greater or lesser attention to these body regions on others? Fifty healthy women (mean age=21.8 years) viewed images of idealized and plus-size models; an eye-tracker recorded visual attention. Participants also completed measures of satisfaction for specific body regions, which were then used as predictors of visual attention to these regions on models. Consistent with an avoidance-type process, lower levels of satisfaction with the two regions of greatest reported concern (mid, lower torso) predicted less attention to these regions; greater satisfaction predicted more attention to these regions. While this visual attention bias may aid in preserving self-esteem when viewing idealized others, it may preclude the opportunity for comparisons that could improve self-esteem.

Full Text Available The development and diversification of the economic activities, the stimulation of investments both in the public sector, but mainly in the private one, the reduction of unemployment, the improvement of living standards are just some of the concepts aimed at by the regional development. The main method which can lead to a balanced development of the regions is financing them differentially so that the underdeveloped regions would obtain proportionally more funds that the developed ones. At a region level, the main objective is represented by the more accelerated growth of the less developed regions, in an effort to diminish the inter-regional and intra-regional development disparities. A key role is played by the sustainable economic growth concept, while also analyzing the competitiveness at a regional level, as well as the main development factors.

2009-05-01

By the methods of in situ investigation and regional ecological planning, the present ecological environment, ecosystem vulnerability, and ecological environment sensitivity in "Ji Triangle" Region were analyzed, and the ecological network of the study area was constructed. According to the ecological resources abundance degree, ecological recovery, farmland windbreak system, environmental carrying capacity, forestry foundation, and ecosystem integrity, the study area was classified into three regional ecological function ecosystems, i. e., east low hill ecosystem, middle plain ecosystem, and west plain wetland ecosystem. On the basis of marking regional ecological nodes, the regional ecological corridor (Haerbin-Dalian regional axis, Changchun-Jilin, Changchun-Songyuan, Jilin-Songyuan, Jilin-Siping, and Songyuan-Siping transportation corridor) and regional ecological network (one ring, three links, and three belts) were constructed. Taking the requests of regional ecological security into consideration, the ecological environment security system of "Ji Triangle" Region, including regional ecological conservation district, regional ecological restored district, and regional ecological management district, was built.

Local actors at community level often thrive for energy autarky to decrease the dependence on imported energy resources. We assess the potentials and trade-offs between benefits and costs of increasing levels of energy autarky for a small rural region of around 21,000 inhabitants in Austria. We use a novel modeling approach which couples a regional energy system model with a regional land use optimization model. We have collected and processed data on the spatial distribution of energy demand and potentials of biomass, photovoltaics and solar thermal resources. The impacts of increasing biomass production on the agricultural sector are assessed with a land-use optimization model that allows deriving regional biomass supply curves. An energy system model is subsequently applied to find the least cost solution for supplying the region with energy resources. Model results indicate that fossil fuel use for heating can be replaced at low costs by increasing forestry and agricultural biomass production. However, autarky in the electricity and the heating sector would significantly increase biomass production and require a full use of the potentials of photovoltaics on roof tops. Attaining energy autarky implies high costs to consumers and a decline in the local production of food and feed. - Highlights: ► Energy autarky strong vision for many regional actors. ► Assessment of consequences of energy autarky for a rural region in Austria. ► Novel modeling approach coupling energy system model with land use model. ► Power and heat autarky causes high costs and decline in regional food and feed production. ► Heat autarky achievable at lower costs by utilizing regional forestry and agricultural biomass.

Regional boundaries study

1978-02-01

The NRC Office of Inspection and Enforcement (IE) has elected to evaluate the effectiveness and efficiency of its existing regional boundary alignment because of the anticipated future growth of nuclear power generating facilities and corresponding inspection requirements. This report documents a management study designed to identify, analyze, and evaluate alternative regional boundary configurations for the NRC/IE regions. Eight boundary configurations were chosen for evaluation. These configurations offered alternatives ranging from two to ten regions, and some included the concepts of subregional or satellite offices. Each alternative configuration was evaluated according to three major criteria: project workload, cost, and office location. Each major criterion included elements such as management control, program uniformity, disruption, costs, and coordination with other agencies. The conclusion reached was that regional configurations with regions of equal and relatively large workloads, combined with the concepts of subregional or satellite offices, may offer a significant benefit to the Office of Inspection and Enforcement and the Commission and are worthy of further study. A phased implementation plan, which is suitable to some configurations, may help mitigate the disruption created by realignment

Full Text Available The article deals with the complex and controversial problems of the new regional communities’ formation and the impact of the interethnic relations sphere on them. The author notes that the processes of interaction between representatives of different cultures and civilizations, ethnic groups and religions have become increasingly controversial and tense in the context of continuous social dynamics. Similarly to the Russian society as a whole, regional communities are in a state of transitivity. They get transformed, they acquire new qualities such as multicasting and heterogeneity, multi-ethnicity and multi-confessionalism, fragmentarity and multiculturality. This fact increases the risks and uncertainties, problematizes future prospects. National non-governmental organizations are increasingly positioning themselves as civil society institutions at the present stage of social development at the regional level. They perform a difficult dual task: on the one hand, they ensure the preservation and development of history, native language, culture, ethnic traditions, and on the other hand, they work on the integration, on the common identity and the Russian nation formation. On the territory of the Volgograd region, largely due to the active cooperation of regional authorities and local authorities with national public associations, international and inter-confessional relations are stable. The basis of such activity is respect for history, native language, culture, tradition, religion, national dignity of all people in the region, regardless of their belonging to a certain ethnic group or religion. Over two decades of accumulated considerable experience of joint inter-ethnic dialogue and cooperation, provided tolerance and peace, harmony and mutual understanding between people of different ethnicities and religions in the country.

Full Text Available This paper presents partial results of a research on consumer preferences when shopping for groceries. It is focused on regional products and consumer preferences in relation to the country of origin of food products. The main objective of this paper is to find the existence of spatial relationships between spatial deployment of regional products and consumer preferences for regional products. It will be necessary to create a data model for monitoring the deployment of regional products and also a data model for tracking important indicators of consumer behavior in all regions of the Czech Republic. The results are based on questionnaire survey that was conducted within the period from October 2010 to January 2011 on a sample of 3767 respondents from the Czech Republic, via both online questionnaires and their printed version. For the data collection the questionnaire system ReLa, developed by the Department of Marketing and Trade at Faculty of Business and Economics at Mendel University in Brno, was used. Data was processed with statistical software STATISTICA (ver. 10. Spatial visualisation was processed with GIS software ArcGIS (ver. 10.1. Preferences for food of Czech origin were analysed in relation to identification criteria. The research results show that the origin of food has an important role in consumer purchase decision-making. There is no significant difference in importance of this factor based on gender of consumers, however, we could prove moderate dependence on respondent’s occupation, education and age.

Regional Air Pollutions in Three Different Regions of Asia From a Transcontinental Transport Perspective

Science.gov (United States)

Pochanart, P.; Kanaya, Y.; Komazaki, Y.; Liu, Y.; Akimoto, H.

2007-12-01

Asia is known as one of the regions with the fastest rate of growing in industrialization and urbanization. As a result, the rapid increases of large-scale air pollution in Asia emerge as a serious concern at both domestic and international levels. Apart from the problems of air quality degradation, emission control, environmental risk, and health effect in a domestic level, evidences from scientific studies indicate that by the long-range transport, Asian air pollution is becoming a global problem. Observations and model studies confirm that air pollution from Asia could be transported to North America or farther. In this work, we investigate the Asian air pollutions, in particular ozone and some other atmospheric components such as carbon monoxide and black carbon, from the ground- based observations in the three different regions, namely 1) background region of Siberia and central Asia, 2) highly anthropogenic region in eastern China, and 3) the rim region of the Asia-Pacific. In a transcontinental transport perspective, these regions are regarded as the inflow region, source region, and outflow region of Asia, respectively. From the results, it is found that the influences from large-scale emission in East Asia are observed clearly in the source region, and to the significant extent in the outflow region. For the inflow region of Asia, our data in Siberia and Kyrgyzstan indicate that air masses in this region are mostly intact from large-scale anthropogenic emission, and remain much of the global background atmospheric pollution characteristic. When the air masses are transported to source region, the air pollutants level increased sharply and frequent episodes of extremely high pollutions have been observed. Our results show good correlation between the residence time of air masses over the source region in eastern China and the observed levels of air pollutants verifying the strong enhancements by anthropogenic emissions from industrialization and

Improving the Assessment of Regional Economic Potential (on Example of Rostov Region

Based on the analysis of existing approaches it is concluded that presence of a number of inherent common disadvantages, which include the exclusion of complex assessment elements of intangible resources, isolation from development goals in the region, ignoring the possibility of incremental reserves development static evaluation results. To overcome these ambiguities the authors' approach to improving assessment procedures based on the allocation of the essential nature of the category «regional economic potential», which unites, on the one hand, the resources available for regional development (actual potential, and on the other hand, resources in respect of which the region has the opportunity to attract them as a tool for further development of (stochastic potential. As the degree of implementation of this option is determined by the quality of regional governance, the most important element of the economic potential of the region is also an effective mechanism for management of existing and potential resources of various types. The practical implementation of the proposed methodology suppose, for example, estimate the economic potential of the Rostov region. At the first stage of the evaluation determine the most important elements of this potential and their ranking, on the second – assessment of the status of these elements from the point of view of their availability, ability to attract and management efficiency, and the third – the normalized assessment of regional economic potential.

Living Mulch Performance in a Tropical Cotton System and Impact on Yield and Weed Control

Directory of Open Access Journals (Sweden)

Vinay Bhaskar

2018-01-01

Full Text Available Cotton (Gossypium hirsutum L. is a major crop in the Vidarbha region of central India. The vertisol soils on which much of the cotton is grown have been severely degraded by the tropical climate, excessive tillage and depletion of organic matter. Living mulches have the ability to mitigate these problems but they can cause crop losses through direct competition with the cotton crop and unreliable weed control. Field experiments were conducted in 2012 and 2013 at four locations in Vidarbha to study the potential for growing living mulches in mono-cropped cotton. Living mulch species evaluated included gliricidia [Gliricidia sepium (Jacq. Kunth ex Walp.], sesbania [Sesbania sesban (L. Merr.], sorghum sudan grass [Sorghum bicolor (L. Moench × Sorghum bicolor (L. Moench ssp. Drummondii (Nees ex Steud. de Wet & Harlan] and sunnhemp (Crotalaria juncea L.. Living mulch height was controlled through mowing and herbicides were not used. Living mulches generated 1 to 13 tons ha−1 of dry matter across sites and years. Weed cover was negatively correlated with both living mulch biomass and cover. Where living mulches were vigorous and established quickly, weed cover was as low as 7%, without the use of herbicides, or inter-row tillage. In a dry year, living mulch growth had a negative impact on cotton yield; however, in a year when soil moisture was not limiting, there was a positive relationship between cotton yield and living mulch biomass. Use of living mulches in cotton production in the Vidarbha region of India is feasible and can lead to both effective weed suppression and acceptable cotton yields.

Numerical conformal mapping and its inverse of unbounded multiply connected regions onto logarithmic spiral slit regions and straight slit regions.

Science.gov (United States)

Yunus, A A M; Murid, A H M; Nasser, M M S

2014-02-08

This paper presents a boundary integral equation method with the adjoint generalized Neumann kernel for computing conformal mapping of unbounded multiply connected regions and its inverse onto several classes of canonical regions. For each canonical region, two integral equations are solved before one can approximate the boundary values of the mapping function. Cauchy's-type integrals are used for computing the mapping function and its inverse for interior points. This method also works for regions with piecewise smooth boundaries. Three examples are given to illustrate the effectiveness of the proposed method.

IS THE POLAR REGION DIFFERENT FROM THE QUIET REGION OF THE SUN?

2010-01-01

Observations of the polar region of the Sun are critically important for understanding the solar dynamo and the acceleration of solar wind. We carried out precise magnetic observations on both the north polar region and the quiet Sun at the east limb with the spectropolarimeter of the Solar Optical Telescope aboard Hinode to characterize the polar region with respect to the quiet Sun. The average area and the total magnetic flux of the kilo-Gauss magnetic concentrations in the polar region appear to be larger than those of the quiet Sun. The magnetic field vectors classified as vertical in the quiet Sun have symmetric histograms around zero in the strengths, showing balanced positive and negative fluxes, while the histogram in the north polar region is clearly asymmetric, showing a predominance of the negative polarity. The total magnetic flux of the polar region is larger than that of the quiet Sun. In contrast, the histogram of the horizontal magnetic fields is exactly the same for both the polar region and the quiet Sun. This is consistent with the idea that a local dynamo process is responsible for the horizontal magnetic fields. A high-resolution potential field extrapolation shows that the majority of magnetic field lines from the kG-patches in the polar region are open with a fanning-out structure very low in the atmosphere, while in the quiet Sun, almost all the field lines are closed.

Evolved H II regions

A probable evolutionary sequence of H II regions based on six distinct types of observed objects is suggested. Two examples which may deviate from this idealized sequence, are discussed. Even though a size-mean density relation of H II regions can be used as a rough indication of whether a nebula is very young or evolved, it is argued that such a relation is not likely to be useful for the quantitative assignment of ages to H II regions. Evolved H II regions appear to fit into one of four structural types: rings, core-halos, smooth structures, and irregular or filamentary structures. Examples of each type are given with their derived physical parameters. The energy balance in these nebulae is considered. The mass of ionized gas in evolved H II regions is in general too large to trace the nebula back to single compact H II regions. Finally, the morphological type of the Galaxy is considered from its H II region content. 2 tables, 2 figs., 29 refs

The most important component of the regional reputational capital is such a significant political resource as the reputation of the regional authorities: good reputation can and should be a key intangible asset of regional management system development aiming to strengthen the authorities decisions and actions and the public confidence, and to mobilize citizens for the real interested participation in the regional management. The article presents the results of testing the research phase of the technological cycle of the regional power reputation management, which was conducted to identify its key essential characteristics and ways for evaluation. The author proposes a research model to study the regional authorities’ reputation and defines the logic of its perception study in terms of two main subjects - the authorities and the population. The results of the assessment of the regional authorities reputation on the example of the Smolensk region let the author examine the coherence of the regional authorities reputation estimates by the public and the authorities themselves (civil servants of the regional executive power and identify a significant gap in the assessments of this reputation by the population as compared to the civil servants opinions.

Regional cooperative agreement for the Asia and Pacific region

Among the means available to the International Atomic Energy Agency to promote cooperative efforts in the nuclear field is the Regional Cooperative Agreement (RCA) for Research, Development, and Training related to Nuclear Science and Technology for the Asia and Pacific Region. Under the terms of this agreement, which came into force on June 12, 1972, participating countries aim to promote and coordinate research, development, and training projects in nuclear fields through collaborative efforts among relevant national institutions in the region. The Agency's role is to provide organizational, administrative, advisory, technical, and financial assistance when needed to secure successful execution of the projects undertaken within the framework of the RCA. Although this presentation deals primarily with the benefits of regional cooperation under the agreement, a review of the RCA would be somewhat imbalanced without a mention of its shortcomings. One of the principal impediments to more rapid progress, as is the case in many other areas, is financing. There is no stable source of funding outside the research contract program and, the likelihood of large-scale UNDP support notwithstanding, a greater willingness on the part of participating Member States to support the program along with the development of a greater sense of common purpose are called for. In this connection serious consideration is being given to the possibility of establishing an Asian Centre for Research and Training, an institute that would bring together scientists from the region to collaborate on problems common to the RCA countries. A study group has already been convened to investigate the feasibility of this proposal

A characteristic trend of many countries modern development is the transition to an innovative economy. At present, this is the only opportunity to secure and maintain a high standard of living for the population. Moreover, innovative development of Russian can be achieved during technological progress in its regions. In this regard, it is necessary to assess the innovative potential of the region and identify the most actual problems that impede the transition to the trajectory of innovative development. The authors outline several main indicators that help to determine the level of innovation and technological development of one of the largest industrial areas of Russia - Kemerovo region. The special economic role of Kemerovo region as a large territorial old-industrial complex of Western Siberia requires a large-scale work to solve the most acute problems of regional development. It is necessary to find the answer for existing problems through the implementation of a system of state regulation aimed at making the innovation component a leading factor of the regional economy competitiveness.

Full Text Available The most part of stimulation methods in Russia are concentrated in legal documents of the regions of the Russian Federation. They directed on intensification of investment activity in regions. How similar are these investment stimulation conceptions? There is no mention in the literature of the methodical questions of quantitative analysis and inter-regional comparisons. In addition, there are no results of statistical research of inter-regional correlations of stimulation methods and analysis of dynamics of this process. There are no special measuring instruments. The presented work is aimed at completion of these blanks. The approach for the spatial correlation analysis of legislative norms is offered in research. Classification of investments’ stimulation methods is developed. The way of preparing and coding data for research is offered. The approach and system of coefficients for the analysis of inter-regional interrelations of legislative systems of investments’ stimulation is offered. A proximity coefficient of regional legislation, a factor of structure similarity and a dynamic coincidence index are proposed. The space-time base of investment stimulation methods on Russian Federation regions for 12 years is collected and statistically processed for research. There are only 758 documents. A source of texts is a site of the Ministry of Justice of the Russian Federation.Research of documents has allowed revealing a number of laws in formation of regional investment stimulation systems. The regions that are the most similar in terms of structure of stimulation methods are identified. We have found the group of regions for which it is observed the increase in similarity of the legislation and the group with the reduction of similarity. Therefore, it is obvious that the general trend to reduction of similarity in the legislation takes place between Krasnoyarsk territory and the other regions of the Russian Federation.

Cho, Seong-Hoon; Kim, Taeyoung; Kim, Hyun Jae; Park, Kihyun; Roberts, Roland K.

2015-01-01

The objective of our research is to predict how electricity demand varies spatially between status quo regionally-uniform electricity pricing and hypothetical regionally-varying electricity pricing across usage categories. We summarize the empirical results of a case study of electricity demand in South Korea with three key findings and their related implications. First, the price elasticities of electricity demand differ across usage categories. Specifically, electricity demands for manufacturing and retail uses are price inelastic and close to unit elastic, respectively, while those for agricultural and residential uses are not statistically significant. This information is important in designing energy policy, because higher electricity prices could reduce electricity demands for manufacturing and retail uses, resulting in slower growth in those sectors. Second, spatial spillovers in electricity demand vary across uses. Understanding the spatial structure of electricity demand provides useful information to energy policy makers for anticipating changes in demand across regions via regionally-varying electricity pricing for different uses. Third, simulation results suggest that spatial variations among electricity demands by usage category under a regionally-varying electricity-pricing policy differ from those under a regionally-uniform electricity-pricing policy. Differences in spatial changes between the policies provide information for developing a realistic regionally-varying electricity-pricing policy according to usage category. - Highlights: • We compare regionally-varying and regionally-uniform electricity pricing policies. • We summarize empirical results of a case study of electricity demand in South Korea. • We confirm that spatial spillovers in electricity demands vary across different uses. • We find positive spatial spillovers in the manufacturing and residential sectors. • Our methods help policy makers evaluate regionally-varying pricing

The evidence on the association between politics and health is scarce considering the importance of this topic for population health. Studies that investigated the effect of different political regimes on health outcomes show inconsistent results. Bayesian time-series cross-section analyses are used to examine the overall impact of regional politics on variations in Italian regional life expectancy (LE) at birth during the period 1980-2010. Our analyses control for trends in and unobserved determinants of regional LE, correct for temporal as well as spatial autocorrelation, and employ a flexible specification for the timing of the political effects. In the period from 1980 to 1995, we find no evidence that the communist, left-oriented coalitions and Christian Democratic, centre-oriented coalitions have had an effect on regional LE. In the period from 1995 onwards, after a major reconfiguration of Italy's political regimes and a major healthcare reform, we again find no evidence that the Centre-Left and Centre-Right coalitions have had a significant impact on regional LE. The presented results provide no support for the notion that different regional political regimes in Italy have had a differential effect on regional LE, even though Italian regions have had considerable and increasing autonomy over healthcare and health-related policies and expenditures.

Promoting regional mobility

DEFF Research Database (Denmark)

Jensen, Anne

Pricing of transport has been part of EU's common transport policy since this gained momentum in the early 1990s. Since then, it has been closely connected to the trans-European transport network (TEN-T) and to rising demands of efficient mobility systems at a local, regional and Community scale....... Development of pricing policies is contested at Community level and has taken place in a clash between different policy rationalities. Significantly though, the effects of the pricing policies are closely related to regional mobility systems, e.g. through financing large trans-border infrastructure projects...... and establishing common technical charging systems thus changing the conditions for regional mobility. This paper explores how policies of infrastructure pricing shape new ways of governing mobility which influences trans-border, regional policy-making. The key findings are that there is a tendency to include...

Social Facilitation: the Kaliningrad Region and Russian Mainland Regions

Directory of Open Access Journals (Sweden)

Toropov Pavel

2015-03-01

Full Text Available The authors look at the concept of social facilitation as a possible component of Russian social consolidation in the course of social reforms. The article focuses on the results of an empirical study of the levels and characteristics of competence in social facilitation, which is here understood as the ability to apply certain knowledge and systems of skills and as a success rate of actions based on experience in improving the conditions of social development. The study was conducted in the Kaliningrad region in 2012—2013. The data was obtained through a survey of 400 respondents using the authors’ methodology encompassing eight basic elements of competence and a structured interview aimed at a better understanding of the subject of the study and attitudes towards it. The data is compared against the results of a similar study in two regions of central Russia with similar conditions. The results suggest a disharmonic and inconsistent structure of competence in social facilitation, low motivation for social activity in youth, and a narrow range of ideas about possible areas of personal activities in the current conditions. Gender differences are identified in the level and structure of competence. The authors believe that certain differences in competence components identified through mathematical methods are determined by the geographical characteristics of the Kaliningrad region — its exclave nature, a relatively small territory, and proximity to the EU countries. It is stressed that the regional conditions affecting motivation, forms and areas of activities, and structure of experience should be taken into account in selecting means and methods of organising youth activities. They can also serve as a basis for the regional youth policy.

Health region development from the perspective of system theory - an empirical cross-regional case study.

Volgger, Michael; Mainil, Tomas; Pechlaner, Harald; Mitas, Ondrej

2015-01-01

Governments are increasingly establishing health regions to deal with current challenges of public health service. These regions are seen as instruments to balance public and private stakeholders, and offer health care to regional citizens as well as to medical/health tourists. However, it is still unclear how the development of such health regions as well as their governance may be conceptualized. We apply Luhmann's system theory approach in the context of a cross-regional case study that compares health region developments in the Autonomous Province of Bolzano-South Tyrol (Italy) with particular regard to the Eastern Dolomites and in the province of Zeeland (the Netherlands). We suggest that Luhmann's system theory provides a useful set of criteria to evaluate and judge health region development. Fully developed health regions can be understood as auto-poietic systems. By emphasizing programs, personnel, and communication channels, these case studies illustrate the suitability of the system theory toolset to analyze the governance and spatial embeddedness of health regions. Additionally, the study contributes to literature by indicating that health regions are closely related to identity issues and to decision making in regions. Copyright © 2014 Elsevier Ltd.

Full Text Available The article deals with the methodical approach to the assessment of a level of development of post-industrial and neoindustrial models of economic modernization in regional aspect on the basis of various indicators. The proposed approach is approved with use of the statistical materials characterizing the state of economy in the regions of Donbass. The strategy of development of Donbass areas and their industrial cities would have to be based (we mean the situation if there were no military operations on this territory on the basis of the model of neoindustrialization assuming development of the sphere of the hi-tech industry, automation and a computerization of productive forces, replacement of physical work by intellectual labor that is radically capable to change nature of work and structure of labor balance of this macro-region. Branches and sectors of a socio-economic complex of the Donbass region using achievements of fundamental and applied science, engineering and design thought for increase in a share of automation, a computerization and mechanization of workplaces, physical and brainwork prior to the beginning of a political conflict in Ukraine have the potential of development. The authors also pay attention to need of studying the agglomerative effect from interaction of the cities and areas of the Donbass euroregion. It is connected, first of all, with development of vertical and horizontal mechanisms of active use of potential of so-called “cities-kernels”, capable to make the catalyzing impact on production, social infrastructure, creation and development of new perspective branches in the cities-satellites.

Regional aerosol emissions and temperature response: Local and remote climate impacts of regional aerosol forcing

Science.gov (United States)

Lewinschal, Anna; Ekman, Annica; Hansson, Hans-Christen

2017-04-01

Emissions of anthropogenic aerosols vary substantially over the globe and the short atmospheric residence time of aerosols leads to a highly uneven radiative forcing distribution, both spatially and temporally. Regional aerosol radiative forcing can, nevertheless, exert a large influence on the temperature field away from the forcing region through changes in heat transport or the atmospheric or ocean circulation. Moreover, the global temperature response distribution to aerosol forcing may vary depending on the geographical location of the forcing. In other words, the climate sensitivity in one region can vary depending on the location of the forcing. The surface temperature distribution response to changes in sulphate aerosol forcing caused by sulphur dioxide (SO2) emission perturbations in four different regions is investigated using the Norwegian Earth System Model (NorESM). The four regions, Europe, North America, East and South Asia, are all regions with historically high aerosol emissions and are relevant from both an air-quality and climate policy perspective. All emission perturbations are defined relative to the year 2000 emissions provided for the Coupled Model Intercomparison Project phase 5. The global mean temperature change per unit SO2 emission change is similar for all four regions for similar magnitudes of emissions changes. However, the global temperature change per unit SO2 emission in simulations where regional SO2 emission were removed is substantially higher than that obtained in simulations where regional SO2 emissions were increased. Thus, the climate sensitivity to regional SO2 emissions perturbations depends on the magnitude of the emission perturbation in NorESM. On regional scale, on the other hand, the emission perturbations in different geographical locations lead to different regional temperature responses, both locally and in remote regions. The results from the model simulations are used to construct regional temperature potential

Faced with free migration, the rich region voluntarily chooses a transfer, which turns out...... to be equal to that a social planner would choose. Provided migration occurs in equilibrium, this conclusion holds even in the presence of moderate mobility costs.

2011-09-01

Full Text Available Transient osteoporosis of the hip and regional migratory osteoporosis are uncommon and probably underdiagnosed bone diseases characterized by pain and functional limitation mainly affecting weight-bearing joints of the lower limbs. These conditions are usually self-limiting and symptoms tend to abate within a few months without sequelae. Routine laboratory investigations are unremarkable. Middle aged men and women during the last months of pregnancy or in the immediate post-partum period are principally affected. Osteopenia with preservation of articular space and transitory edema of the bone marrow provided by magnetic resonance imaging are common to these two conditions, so they are also known by the term regional transitory osteoporosis. The appearance of bone marrow edema is not specific to regional transitory osteoporosis but can be observed in several diseases, i.e. trauma, reflex sympathetic dystrophy, avascular osteonecrosis, infections, tumors from which it must be differentiated. The etiology of this condition is unknown. Pathogenesis is still debated in particular the relationship with reflex sympathetic dystrophy, with which regional transitory osteoporosis is often identified. The purpose of the present review is to remark on the relationship between transient osteoporosis of the hip and regional migratory osteoporosis with particular attention to the bone marrow edema pattern and relative differential diagnosis.

Biomonitoring provides a useful tool to estimate the genetic risk from exposure to genotoxic agents. The aim of this study was to assess the potential cytogenetic damage associated with occupational exposure to hexavalent chromium by using micronuclei (MN) as a biomarker. This was a cross-sectional study and all participants were males. Both the exposed and control individuals were selected from Coimbatore, Southern India. Exfoliated buccal cells from 44 chrome plating workers and 40 age and sex matched control subjects were examined for MN frequency and nuclear abnormalities (NA) other than micronuclei, such as binucleates, broken eggs, karyorrhexis, karyolysis and pyknosis. Results showed statistically significant difference between chrome plating workers and control groups. MN and NA frequencies in chrome plating workers were significantly higher than those in control groups (p chrome plating workers are under risk of significant cytogenetic damage. Therefore, there is a need to educate those who work with heavy metals about the potential hazard of occupational exposure and the importance of using protective measures.

Basu, S.; Basu, S.; MacKenzie, E.; Coley, W.R.; Hanson, W.B.; Lin, C.S.

1984-01-01

Spectral characteristics of auroral F region irregularities were studied by the use of high-resolution (approx.35 m) density measurements made by the retarding potential analyzer (RPA) on board the Atmosphere Explorer D (AE-D) satellite during two orbits when the satellite was traversing the high-latitude ionosphere in the evening sector. Coordinated DMSP passes provided synoptic coverage of auroral activity. The auroral energy input was estimated by intergrating the low-energy electron (LEE) data on AE-D. It was found that the one-dimensional in situ spectral index (p 1 ) of the irregularities at scale lengths of 1 values of approx.-3. This is interpreted as resulting from the effects of E region conductivity on the F region irregularity structure. The regions in between the precipitation structures, where presumably the E region conductivity was small, were generally associated with large shears in the horizontal E-W drifts and large velocities, as measured by the ion drift meter on board AE-D. The maximum drifts measured were approx.2 km s -1 , corresponding to an electric field of 100 mV m -1 . The large-velocity regions were also associated with substantial ion heating and electron density depletions. The largest shear magnitudes observed were approx.80 m s -1 km -1 , and the shear gradient scale lengths were approx.10 km, which was approximately the resolution of the ion drift meter data set used. The spectral characteristics of irregularities in the large, variable flow regions were very different, with p 1 being approx.-1

Food Independence of the Region

Directory of Open Access Journals (Sweden)

Vasiliy Vladimirovich Tyutyunik

2016-06-01

Full Text Available The article deals with such basic definitions as food security, food independence and food self- sufficiency of the region. The author shows the ambiguity problem of interpretations of these terms in the Russian legislation, which is especially evident in the transition from the national to the regional level. Using the example of legislative acts of some of the Russian Federation’s subjects the study demonstrates the incorrect use of mentioned terms. In author’s opinion, regional authorities in the Russian Federation must introduce amendments to the legislative documents concerning food security. To be more concrete, the regional authorities should either deny the goal of food independence for a particular region, or specify that the goal of reaching food independence for the region does not mean food self-sufficiency, but just import substitution on the regional level

Self-organizing map network-based precipitation regionalization for the Tibetan Plateau and regional precipitation variability

Science.gov (United States)

Wang, Nini; Yin, Jianchuan

2017-12-01

A precipitation-based regionalization for the Tibetan Plateau (TP) was investigated for regional precipitation trend analysis and frequency analysis using data from 1113 grid points covering the period 1900-2014. The results utilizing self-organizing map (SOM) network suggest that four clusters of precipitation coherent zones can be identified, including the southwestern edge, the southern edge, the southeastern region, and the north central region. Regionalization results of the SOM network satisfactorily represent the influences of the atmospheric circulation systems such as the East Asian summer monsoon, the south Asian summer monsoon, and the mid-latitude westerlies. Regionalization results also well display the direct impacts of physical geographical features of the TP such as orography, topography, and land-sea distribution. Regional-scale annual precipitation trend as well as regional differences of annual and seasonal total precipitation were investigated by precipitation index such as precipitation concentration index (PCI) and Standardized Anomaly Index (SAI). Results demonstrate significant negative long-term linear trends in southeastern TP and the north central part of the TP, indicating arid and semi-arid regions in the TP are getting drier. The empirical mode decomposition (EMD) method shows an evolution of the main cycle with 4 and 12 months for all the representative grids of four sub-regions. The cross-wavelet analysis suggests that predominant and effective period of Indian Ocean Dipole (IOD) on monthly precipitation is around ˜12 months, except for the representative grid of the northwestern region.

Regions and the Territorial Cohesion

Directory of Open Access Journals (Sweden)

Ioan Ianos

2013-08-01

Full Text Available Territorial cohesion is an important target of European Union, constantly promoted by its institutions and their representatives. In the context of the Europe 2020 strategy, one of the most important support documents, the region represents a very important issue, being considered to be the key to its successfulness. The region is seen as a support for the smart growth and all the operational policy concepts try to make use of the spatial potential, by taking better account of the territorial specificities. Two main questions play attention: the need to transform the present-day developmental regions into administrative ones is a priority? What kind of regionalization it must to be promoted? Correlating these issues with already defined territorial cohesion, the administrative region is a real tool for the future territorial development. The experience of the last 14 years asks urgently the building of a new territorial administrative reform, giving competences to regions. For instant, each development region is a construction resulted from a free association of the counties. Their role in the regional development is much reduced one, because their regional councils are not elected; decisions taken at this level are consultative for the social, economical, cultural or political actors.

Cooperative monitoring of regional security agreements

1996-11-01

This paper argues that cooperative monitoring plays a critical role in the implementation of regional security agreements and confidence building measures. A framework for developing cooperative monitoring options is proposed and several possibilities for relating bilateral and regional monitoring systems to international monitoring systems are discussed. Three bilateral or regional agreements are analyzed briefly to illustrate different possibilities. These examples illustrate that the relationship of regional or bilateral arms control or security agreements to international agreements depends on a number of factors: the overlap of provisions between regional and international agreements; the degree of interest in a regional agreement among the international community; efficiency in implementing the agreement; and numerous political considerations. Given the importance of regional security to the international community, regions should be encouraged to develop their own infrastructure for implementing regional arms control and other security agreements. A regional infrastructure need not preclude participation in an international regime. On the contrary, establishing regional institutions for arms control and nonproliferation could result in more proactive participation of regional parties in developing solutions for regional and international problems, thereby strengthening existing and future international regimes. Possible first steps for strengthening regional infrastructures are identified and potential technical requirements are discussed.

Teaching anti-corruption in the caucasus and black sea region(s

Directory of Open Access Journals (Sweden)

Thomas Kruessmann

2017-09-01

Full Text Available There is hardly a topic in the current transformations that is as central as corruption. Anti-corruption efforts go back to the nineties when globalisation turned the world into a corporate playing field. Since then, a wealth of tools and instruments has been invented, and any student of anti-corruption can be certain to find abundant materials. From a teacher’s perspective, turning these materials into a coherent academic subject is the first challenge. But anti-corruption is not a subject like any other. If taught properly, it should challenge every student’s moral compass and become a catalyst for the development of professional ethics. Anybody who has ever been forced to pay bribes in a university setting will remember «turning red with shame». Bribing your teacher, as compared to a traffic police or customs officer, seems like the ultimate betrayal of the notion of the intellectual community between scholar/teacher and student, and it throws into doubt the entire system of values and goals that higher education stands for. In its effect, it is as pernicious as doping in sports. And when the shame is overcome, the result will be a graduate who is «street-wise», who is ready to play the game and expect nothing less from his or her colleagues. Against this background, the purpose of this paper is twofold. It serves as a reflection on the state of anti-corruption efforts in the Black Sea and Caucasus region(s and suggests a model how electronic resources could become a catalyst in bringing blended learning/teaching on anti-corruption to the region(s. At the same time, it develops the scholarly argument that the «toolkit box approach» favoured by the United Nations Office on Drugs and Crime (UNODC is not sufficient to address the root causes of corruption in the region(s. As an alternative and to the extent that it concerns the Black Sea and Caucasus region(s, it is suggested to place anti-corruption more firmly into the context of

The Regional Cooperation Agreement (RCA) for Research Development and Training Related to Nuclear Science and Technology, formulated under the auspices of the International Atomic Energy Agency (IAEA), came into force in June 1972. The overall objective of RCA is to promote technical cooperation among the developing and developed countries in the Asia Pacific region in the peaceful uses of nuclear energy and related technology. Currently, the biggest project under RCA is the Regional Project on the Industrial Applications of Isotopes and Radiation Technology for Asia and the Pacific. The project was established in 1982 for a period of five years and was completed in December 1986. The first phase of the project has generated a high degree of awareness on the industrial potential of isotopes and radiation technology throughout the region; produced a cadre of trained manpower in all areas covered by the project; identified the expertise available in the region; and developed in the region, a unique network of people and institutions involved with the utilization of isotope and radiation technology. A Phase II of the project, which cover all but one of the sub-projects under Phase I, was approved in early 1987 for another five years until 1991. (Nogami, K.)

Yunbo Chu

2016-10-01

Full Text Available Economic evaluation in the form of cost-effectiveness analysis has become a popular means to inform decisions in healthcare. With multi-regional clinical trials in a global development program becoming a new venue for drug efficacy testing in recent decades, questions in methods for cost-effectiveness analysis in the multi-regional clinical trials setting also emerge. This paper addresses some challenges from variation across regions in cost effectiveness analysis in multi-regional clinical trials. Several discussion points are raised for further attention and a multi-regional clinical trial example is presented to illustrate the implications in industrial application. A general message is delivered to call for a depth discussion by all stakeholders to reach an agreement on a good practice in cost-effectiveness analysis in the multi-regional clinical trials. Meanwhile, we recommend an additional consideration of cost-effectiveness analysis results based on the clinical evidence from a certain homogeneous population as sensitivity or scenario analysis upon data availability.

This paper argues that cooperative monitoring plays a critical role in the implementation of regional security agreements and confidence building measures. A framework for developing cooperative monitoring options is proposed and several possibilities for relating bilateral and regional monitoring systems to international monitoring systems are discussed. Three bilateral or regional agreements are analyzed briefly to illustrate different possibilities: (1) the demilitarization of the Sinai region between Israel and Egypt in the 1970s; (2) the 1991 quadripartite agreement for monitoring nuclear facilities among Brazil, Argentina, The Argentine-Brazilian Agency for Accounting and Control of Nuclear Materials and the International Atomic Energy Agency; and (3) a bilateral Open Skies agreement between Hungary and Romania in 1991. These examples illustrate that the relationship of regional or bilateral arms control or security agreements to international agreements depends on a number of factors: the overlap of provisions between regional and international agreements; the degree of interest in a regional agreement among the international community; efficiency in implementing the agreement; and numerous political considerations.Given the importance of regional security to the international community, regions should be encouraged to develop their own infrastructure for implementing regional arms control and other security agreements.

Regional versus local influences on lead and cadmium loading to the Great Lakes region

Yohn, S.; Long, D.; Fett, J.; Patino, L. [Michigan State University, East Lansing, MI (United States). Dept. of Geological Science

2004-07-01

Environmental legislation has reduced the anthropogenic loadings of Pb and Cd to the Great Lakes region over the past 3 decades. However, the accumulation rates of these metals still remain above background values. Because environmental legislation was targeted at major sources (e.g., Pb in gasoline) whose influence on the environment was on a regional scale, local sources (e.g., watershed scale) for the metals may now play a more significant role. The relative importance of regional versus local scale influences on metal inputs to the environment is poorly understood. In this study, sediment chronologies of Pb and Cd were examined from 12 inland lakes that cover the broad geographic area of the State of Michigan. These chronologies were compared temporally and spatially and to watershed population densities and metal production records to gain an understanding of local and regional influences on metal inputs to the Great Lakes region. Results show that anthropogenic Pb loading during the 1930s and 1970s was dominated by regional sources. such as coal burning and use of leaded gasoline. Current loadings are now more related to local influences such as watershed population densities, rather than atmospheric deposition. Anthropogenic Cd loadings to the Great Lakes region have been dominated by both regional and local sources over time. Lead may also have shown the influence of local sources over time, if the influence of emissions from gasoline had not been present. This work shows that Pb and Cd loadings in the Great Lakes region are strongly related to watershed population densities; however, the specific sources and pathways for the metal cycling are unclear.

In China, great differences in economy, social characteristics and hygiene exist between developing and developed regions. A comparative study of infectious diarrhea between two regions was needed. Three groups of diarrheal patients were collected: children ≤5 year-olds from Beijing (developed region) and Henan Province (developing region), and adults over 18 year-olds from Beijing. A questionnaire was used to survey and feces samples were examined for 16 enteropathogens. We enrolled 1422 children and 1047 adults from developed region and 755 children from developing region. Virus positive rates were 32.98% for children and 23.67% for adults in developed region. The most prevalent pathogen for children was rotavirus whereas for adults was norovirus. Bacterial isolation rates were 13.92% for children from developed region, while 29.14% for children from the developing regions. For the greatest difference, Shigella accounted for 50.79% and was the dominant pathogen in the developing region, whereas in the developed region it was only 1.45%. There was no significant relationship between the local levels of development with diarrheogenic Escherichia coli (DEC) categories. But it was seen the notable differences between the population with different age: enteropathogenic E.coli (EPEC) and enteroaggregative E.coli (EAggEC) were the primary classes of DEC in children from both regions, whereas it was enterotoxigenic E.coli (ETEC) in adults. The symptoms of Shigella and Salmonella infection, such as bloody stools, white blood cells (WBC) and red blood cells (RBC) positivity and fever were similar in children, which may lead to the misidentification. Yersinia enterocolitica and shiga toxin-producing E.coli (STEC) infections were firstly reported in Beijing. There was a large difference in etiology of bacterial diarrhea between children in developing and developed regions of China.

The north-east Baffin Bay region, offshore Greenland - a new frontier petroleum exploration region

Energy Technology Data Exchange (ETDEWEB)

Gregersen, U. (Geological Survey of Denmark and Greenland, Copenhagen (Denmark))

2008-07-15

In recent years the Arctic has come into focus for hydrocarbon exploration, and areas offshore both West and East Greenland have been evaluated as promising frontier hydrocarbon provinces. Seven hydrocarbon exploration and exploitation licenses were awarded in 2007-2008 offshore the Disko-Nuussuaq region, and two more have been awarded in the open-door region offshore south-western Greenland. In 2007, an extensive amount of new seismic and aero-magnetic data was acquired by the TGS-NOPEC Geophysical Company in the north-eastern Baffin Bay region. Geophysical mapping has been initiated by the Geological Survey of Denmark and Greenland (GEUS) in the Melville Bugt region offshore North-West Greenland with the purpose of evaluating the hydrocarbon prospectivity. Initial interpretation of seismic and gravity data suggests the presence of deep sedimentary basins separated by structural highs. Geological information on source rock, reservoir rock and seal intervals from surrounding regions suggest that the Melville Bugt region is likely to have a significant petroleum potential. The study is based on public domain magnetic and gravity data, and all proprietary and public 2-D seismic data acquired before 2003. Seismic horizons from the 'seismic basement' to 'base Quaternary' are being interpreted regionally. Based on the seismic interpretation, a structural element map, depth-structure maps and isopach maps will be produced in order to assess the prospectivity of the Melville Bugt region. (au)

Objective: We aimed to improve diagnostic accuracy of 18 F-fluoro-2-deoxyglucose (FDG) PET/CT for gastric cancer with water gastric inflation. Materials and methods: 44 gastric cancer patients (M:F = 30:14, age ± std = 62.1 ± 14.5y) were enrolled before surgery. Fifty minutes after injection of FDG (0.14 mCi/kg body weight), whole body PET/CT was performed first and then regional PET/CT over gastric area was obtained 80 min post FDG injection after water gastric inflation. Diagnostic accuracies for loco-regional lesions were compared between whole body and regional PET/CT. Results: 48 primary tumors (23 EGC and 25 AGC) and 348 LN stations (61 metastatic and 287 benign) in 44 patients were investigated. Primary tumor sensitivity of whole body PET/CT (50% = 24/48) was significantly improved by regional PET/CT (75% = 36/48, p < 0.005). Sensitivity of whole body PET/CT (24.6% = 15/61) for LN metastasis was also significantly improved by regional PET/CT (36.1% = 22/61, p < 0.01), whereas specificity of whole body PET/CT (99.3% = 285/287) was not compromised by regional PET/CT (98.3% = 282/287, p > 0.05). Higher primary tumor FDG uptake in regional PET/CT indicated shorter progress-free survival (p = 0.0003). Conclusion: Diagnostic accuracy of whole body PET/CT for loco-regional disease of gastric cancer could be significantly improved by regional PET/CT after water gastric inflation and prognosis could be effectively predicted by primary tumor FDG uptake in regional PET/CT

Full Text Available Local governance is a broad concept and is defined as the formulation and execution of collective action at the local level. The purpose of local government is to ensure effective and efficient use of public resources and service delivery at the level closest to citizens. Regional development is a new concept that aims to stimulate and diversify the economic activity of a country (region, to encourage investment in the private sector, to create a new jobs vacancy and improves living standards of the country. Regional development policies are a number of measures designed and promoted by the central and local administration, but the cooperation undertaken at the actors are in a different one, which included the private sector and civil society. At the center of these regional policies or practices is the use of efficient potential of each region, being particularly focused on business, means promoting the development of the new enterprises, promoting labor market and investment, improve the quality of environment, health , education and culture. Traditional objective of regional development policies is the reduction of territorial disparities for achieving a relative balance between economic and social levels of development in different areas in the national territory. Regional development is the actual task of local government units in Albania, and is one of the tasks and challenges of the future. Currently it takes a special importance in the context of European Union integration. Reforms have begun to change the system in 1990 in order to implement local democracy and decentralization principles that are present today. Inequalities that exist within the region and between them indicate that in some regions the economic potential is not being fully utilized, and that it reduces the overall performance in national level.

The region matters: A comparative analysis of regional energy efficiency in Spain

International Nuclear Information System (INIS)

Ruiz-Fuensanta, María J.

2016-01-01

Owing to its strategic nature, the Spanish energy policy is primarily the responsibility of the central state. In spite of this, the Spanish legal code does in fact also confer certain powers to territorial governments in Spain, the Autonomous Communities. The objective of this work is specifically to investigate the differences between the energy performance of Spanish regions, which may be a consequence of specific features of their productive structures and resource endowments, in addition to the specific decisions adopted by each of them within the scope for action that they have in this area. With this aim in mind, we intend to calculate the inefficiency levels of Spanish regions as regards their use of various energy sources during the period 2003–2008, by estimating an environmental directional distance function. The results obtained confirm the existence of significant differences in the behaviour and evolution of regional energy efficiency and point to the need to pay more attention to energy planning in this territorial sphere. - Highlights: • Energy efficiency of Spanish regions by energy source is investigated. • The environmental directional distance function is used for the analysis. • Significant differences among regions in energy efficiency are observed. • Level of development and industrialization are not determinant to explain them.

Hanley, W; Mayeda, K; Myers, S; Pasyanos, M; Rodgers, A; Sicherman, A; Walter, W

1999-01-01

As part of the Department of Energy's research and development effort to improve the monitoring capability of the planned Comprehensive Nuclear-Test-Ban Treaty international monitoring system, Lawrence Livermore Laboratory (LLNL) is testing and calibrating regional seismic discrimination algorithms in the Middle East, North Africa and Western Former Soviet Union. The calibration process consists of a number of steps: (1) populating the database with independently identified regional events; (2) developing regional boundaries and pre-identifying severe regional phase blockage zones; (3) measuring and calibrating coda based magnitude scales; (4a) measuring regional amplitudes and making magnitude and distance amplitude corrections (MDAC); (4b) applying the DOE modified kriging methodology to MDAC results using the regionalized background model; (5) determining the thresholds of detectability of regional phases as a function of phase type and frequency; (6) evaluating regional phase discriminant performance both singly and in combination; (7) combining steps 1-6 to create a calibrated discrimination surface for each stations; (8) assessing progress and iterating. We have now developed this calibration procedure to the point where it is fairly straightforward to apply earthquake-explosion discrimination in regions with ample empirical data. Several of the steps outlined above are discussed in greater detail in other DOE papers in this volume or in recent publications. Here we emphasize the results of the above process: station correction surfaces and their improvement to discrimination results compared with simpler calibration methods. Some of the outstanding discrimination research issues involve cases in which there is little or no empirical data. For example in many cases there is no regional nuclear explosion data at IMS stations or nearby surrogates. We have taken two approaches to this problem, first finding and using mining explosion data when available, and

Renewable generation across Italian regions: Spillover effects and effectiveness of European Regional Fund

International Nuclear Information System (INIS)

Carfora, Alfonso; Romano, Antonio A.; Ronghi, Monica; Scandurra, Giuseppe

2017-01-01

This paper investigates on the determinant factors that drive the Italian regions toward a sustainable development path and evaluates the effectiveness of European Regional Development incentives in promoting investments in renewable energy sources (RES). Starting from the consideration that there are spillover effects between similar regions, first we identify the factors that capture these similarities, then we use them to evaluate their relevance in determining the success of the investments in RES. An econometric analysis, based on the use of spatial panel specification model, is implemented to support the hypotheses. Two important results emerge from the study. The first is the identification of regional determinants of RES production, that are driven by the similarities between regions, and that can be interpreted as guidelines in the policy choices in support of investments. The second is the lack of effectiveness of the incentives in support of RES. Results indicate that the capacity of some regional governments to direct the funds allocated by the central government or European Commission towards efficient production of renewable energy is likely limited, and these incentives have been undone. - Highlights: • Investments in renewable energies makes a remarkable contribution to reduce unemployment. • In Italy there is a lack of effectiveness of the incentives in support of renewable energies. • To attract energy investments regions must reduce the burden of taxation. • Highly deprived areas incentivize more than the developed ones renewable energies. • Production of renewable energies is directly influenced by the production in similar regions.

Full Text Available Aim of this work is to evaluate factors responsible for these developments and to show chances for other regions by adopting thismarketing strategy. Besides marketing, interaction of tourism, industry and state was important. Many reasons can be found that shouldresult in a worse development of the region around the Lake of Constance . But instead, today this region has a higher populationgrowth than the average of Baden-Württemberg and is the best economic region outside of urban centers. Scientists spoke aboutan overheated economic growth during the last years that in 2008 comes to a normal but still high level. To attract high potentialworkers and engineers to support further growth, the region has one main advantage to many other regions – its environment. In caseof “Lake of Constance” region, different marketing strategies were used. The complexity of successful marketing for a region is highand finding the right combination of marketing strategies is difficult but can positively influence the development of a region, itseconomy and tourism. At the same time, the marketing for economy and tourism positively reflects degree of popularity in the region.

The D-region of the ionosphere

International Nuclear Information System (INIS)

Mitra, A.P.

1978-01-01

The D-region of the ionosphere, traditionally defined as the region of ionization below 100 km, is a link between the non-ionized stratosphere below and the dense plasma above. In it, minor neutral constituents play a dominant role and chemical reactions, both neutral and ionic, are dominant. It plays a very important role in the propagation of radiowaves at all frequencies below 30 MHz, and is particularly important in effecting communication over areas of the earth, such as polar regions, that are inaccessible to synchronous satellite links. Work which has been carried out on the neutral environment, D-region ionization, positive and negative ions found in the D-region, disturbances in the D-region (of solar origin and due to local dynamics or thermal changes), and the chemistry of the region, is considered. Possible future D-region studies are outlined. (UK)

Second region of stability

Greene, J.M.; Chance, M.S.

1980-10-01

A new type of axisymmetric magnetohydrodynamic equilibrium is presented. It is characterized by a region of pressure and safety factor variation with a short scale length imposed as a perturbation. The equilibrium consistent with these profile variations can be calculated by means of an asymptotic expansion. The flexibility obtained by generating such equilibria allows for a close examination of the mechanisms that are relevant to ballooning instabilities - ideal MHD modes with large toroidal mode number. The so-called first and second regions of stability against these modes are seen well within the limits of validity of the asymptotic expansion. It appears that the modes must be localized in regions with small values of the local shear of the magnetic field. The second region of stability occurs where the local shear is large throughout the range where the magnetic field line curvature is destabilizing

Dust in H II regions

International Nuclear Information System (INIS)

Isobe, S.

1977-01-01

Several pieces of evidence indicate that H II regions may contain dust: 1) the continuum light scattered by dust grains (O'Dell and Hubbard, 1965), 2) thermal radiation from dust grains at infrared wavelengths (Ney and Allen, 1969), 3) the abnormal helium abundance in some H II regions (Peimbert and Costero, 1969), etc. Although observations of the scattered continuum suggest that the H II region cores may be dust-free, dust grains and gas must be well mixed in view of the infrared observations. This difficulty may be solved by introducing globules with sizes approximately 0.001 pc. These globules and the molecular clouds adjacent to H II regions are the main sources supplying dust to H II regions. (Auth.)

Evaluating the Impact of Regional Marketing Projects on the Development of Regions from Different Stakeholder Perspectives

Directory of Open Access Journals (Sweden)

Kunze Kim-Kathrin

2014-01-01

Full Text Available In the competition for economically attractive stakeholders, regions have to implement strategies to gain and adhere those interest groups. Empirical studies concerning the migration motivations show that it is not only labor market but also soft locational factors of the social environment, nature and landscape that are of high importance: A majority of the population is willing to move or rather stay at a special place because of such soft locational factors. This study examines the impact of regional marketing projects on the development of regions from the perspectives of inhabitants and tourists as well as general attributes to measure a region’s attractiveness from the perspective of high potentials. We argue that those projects that fit to the region and its unique selling propositions contribute to positioning and building location brand value. We show that projects have a socio-economic effect on the attitude towards regions and contribute to building location brand value. An analysis of group differences shows that the project influence on the region and region attractiveness are perceived in significantly different manner depending on the knowledge level of the stakeholder group. Consequently, one should increase the awareness of marketing activities and regions and focus on soft locational factors while establishing and positioning a region brand.

BUDGETARY REGIONAL POLICY: THEORETICAL CONCEPTUALIZATION

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Introduction. Formation and implementation of the budget policy of the regions in Ukraine is directly related to the processes of decentralization of power, increase of budget powers and strengthening of financial capacity of the territories. Formation of balanced local budgets and support of an effective system of managing budget resources is a key to strengthening the economic potential of the regions and increasing the well-being of citizens. The purpose of this article is to assess the current concepts of the fiscal policy of the region in Ukraine and to determine the impact of fiscal policy on the socio-economic development of the regions. Results. In this article the essence and content of budget policy are considered, the interpretation of different scientists is presented. An author’s approach to the definition of the essence of the budget policy of the region as a set of economic and administrative measures in the budget sphere, determined by the interrelated goals and objectives of the state and local self-government, aimed at the socio-economic development of the territory. The conceptual model of the fiscal policy of the region is presented and it is determined that the strategic goal of fiscal policy at the local level should be to ensure sustainable socio-economic development of the territories. The main principles that need to be observed during the implementation of the budget policy of the region are described; functions to be performed by local level fiscal policy; and the main tools by which local authorities carry out their functions. Conclusions. It is noted that the content of the budget policy of the region should be to determine the course, tasks and directions of the state and local self-government activities in the field of the formation and use of budget funds. The budget policy of the region should respond to a combination of the following systemic challenges: 1. the restoration of economic growth, as soon as

The role of regional pollution conventions

International Nuclear Information System (INIS)

Haywar, P.

1989-01-01

Within the last 12 years a number of regional pollution conventions and action plans have been negotiated to protect the world's seas from pollution. This paper traces the development of this activity and points out the specific role of regional, as opposed to global, pollution conventions. Chief among the functions of regional conventions is the specific legal framework they provide for a particular geographical region. They also provide a forum for neighboring states to develop a coherent policy for a particular regional sea, as well as being the means of establishing regional control over potentially polluting activities. Regional agreements also constitute a suitable framework for monitoring the input of pollutants to the marine environment and assessing their effects. In addition, they provide a forum for the exchange of scientific and technical information and for developing cooperation between states. The paper concludes by summarizing the most important functions of a regional convention and suggesting that, with increasing industrialization and pollution stress, there will continue to be a need for action to be taken at the regional level

Water masers in NGC7538 region

Kameya, Osamu

We observed H2O masers towards NGC7538 molecular-cloud core using VERA (VLBI Experiment of Radio Astrometry). This region is in the Perseus arm at a distance of about 2.7 kpc and is famous for its multiple, massive star formation. There are three areas there, N(IRS1-3), E(IRS9), and S(IRS11), each having a strong IR source(s), ultra-compact HII region(s), bipolar outflow, high-density core, and OH/H2O/CH3OH masers. We made differential VLBI observations towards the NGC7538 H2O maser sources at N and S and a reference source, Cepheus A H2O maser, simultaneously. The Cepheus A region is separated by 2 degrees from the NGC7538 region. The positions of H2O masers in N and S regions, distributed around the ultra-compact HII regions, are basically consistent with those found by means of interferometric observations of past 29 years. The masers may come from interface regions between the ultra-compact HII regions and the environments of dense molecular gas.

Growth-based Theories for Declining Regions? A Note on Conceptualisations of Demographic Change for Regional Economic Development

Directory of Open Access Journals (Sweden)

Anke Matuschewski

2016-01-01

Full Text Available This article aims to critically assess the economic growth paradigm, which typically underlies most approaches to regional policymaking for demographic change. While population losses, ageing and outmigration – i.e. phenomena that are addressed as demographic change – have become a matter of urgency for many European regions, most regional economic development theories remain silent about the population decline affecting the economic growth and development prospects of regions. Consequently, regional policies usually rely on the concept of economic growth, yet neglect the complexity and importance of demographic change and how it relates to the economic sphere. Due to this lack in nuance, we argue that regional policymaking fails to design adequate policy support for regions facing persistent demographic change and economic stagnation or decline as a result. Based on these observations, the paper examines a selection of regional economic development theories in search for alternative concepts of growth and development in the context of demographic change. To this aim, globalisation peripheries are introduced as a fruitful conceptual point of reference and, in combination with endogenous regional development theories, discussed as an alternative approach for regional policymaking.

Working memory is the limited capacity storage system involved in the maintenance and manipulation of information over short periods of time. Previous imaging studies have suggested that the frontoparietal regions are activated during working memory tasks; a putative association between the structure of the frontoparietal regions and working memory performance has been suggested based on the analysis of individuals with varying pathologies. This study aimed to identify correlations between white matter and individual differences in verbal working memory performance in normal young subjects. We performed voxel-based morphometry (VBM) analyses using T1-weighted structural images as well as voxel-based analyses of fractional anisotropy (FA) using diffusion tensor imaging. Using the letter span task, we measured verbal working memory performance in normal young adult men and women (mean age, 21.7 years, SD=1.44; 42 men and 13 women). We observed positive correlations between working memory performance and regional white matter volume (rWMV) in the frontoparietal regions. In addition, FA was found to be positively correlated with verbal working memory performance in a white matter region adjacent to the right precuneus. These regions are consistently recruited by working memory. Our findings suggest that, among normal young subjects, verbal working memory performance is associated with various regions that are recruited during working memory tasks, and this association is not limited to specific parts of the working memory network.

Full Text Available Searching of sources to increase the capitalization of Russian banks is an important economic problem for both the national and regional economy. Moreover, a strong capital base allows to credit institutions to meet the demands of economic agents for banking service. The research focuses on the choice of sources of regulatory capital for the banks of Tyumen region in the context of changing supervisory requirements in the period of 2005–2016, in different phases of the business cycle. We apply econometric methods of statistical information using IBM SPSS Statistics software. We have calculated the individual correlations of regional banks’ capital with gross domestic product (GDP (excluding gross regional product (GRP and GRP (with the exception of the effect of GDP. These calculations have shown that the capital of regional banks is related only to GDP. The increase in the capital of regional banks is accompanied by a change in its structure: the share of authorized capital has halved, and the share of subordinated debt has grown. All sources of capital, other than the reserve fund, are related to GDP. Authorized capital is associated with the profit of profitable lending institutions; retained earnings in the capital of regional banks — with the aggregated amount of risks of the banking system of the Russian Federation. Subordinated debt, like capital as a whole, is negatively affected by the profitability of the banking sector. The change in the capital of regional banks is determined by the change in retained earnings, subordinated debt and reserve fund. Modelling of these relations has allowed to obtain a system of equations. This system synthesizes linear regression models of changing the capital of regional banks in the context of their sourcing. The results of this study are significant for theoretical justification and practical development of a balanced financial policy of regional banks. Our research will contribute to

This paper reviews the extensive forms of Asia-Pacific regional cooperation in nuclear power to develop and provide economical and reliable energy supply for sound economical growths of developing countries in this region, which has seen rapid growth of energy consumption more than anywhere else in recent years. Nuclear power has received keen attention from DCs because it can provide a self-reliable energy supply and promote development of high technology in the associated engineering and manufacturing industries locally. However, due to the particular characteristics in nuclear power technology, a close cooperation is required between the seller(industrialized) and buyer(developing) countries. The Asia-Pacific regional cooperation in nuclear power is a step toward providing mutual benefits to the countries involved in this region, and this paper explores potential ways in formulating basic and systematic approaches and areas of full scope cooperation.

Full Text Available This paper presents results from a regional policy evaluation study conducted for the European Commission. The study examined the impact of the European Regional Development Fund and Cohesion Fund on EU regions with ‘specific geographical characteristics’, namely islands, mountain regions and sparsely populated areas. These types of regions have been attracting increasing EU regional policy attention and their economic development is considered important in helping the EU to attain its important ‘territorial cohesion’ objective. The focus of this paper is on the island regions. Evaluation of island regions in their own right has not been undertaken before by the EU. The study focuses on the 2000-06 and (still on-going 2007-13 EU regional policy programs. The paper presents the methodology adopted by the study before turning to the main findings concerning the types of policy initiatives adopted in the island regions, and the appropriateness of the policies used for the economic situation faced by the islands. The islands encompassed by the study are all normal sub-national regions of EU member states. Islands with an unusual degree of administrative autonomy (e.g. the Outermost Regions were excluded.

Regional Climate models are more and more needed to provide high resolution regional climate information in climate impact studies. Water availability in a future scenario is the main request of policy makers for adaptation and mitigation purposes. However precipitation changes are unlikely to be as spatially coherent as temperature changes and they are closely related to the regional model itself. In addition model skill varies regionally. An example of several ICTP regional climate model (RegCM3) simulations is reported over China, Korea, Africa, Central and Southern America, Europe and Australia. Over China, Australia, and Korea the regional model improves the simulation compared to the driving GCM when compared with CRU observations. In China, for example, the higher resolution of the regional model inhibits the penetration of the monsoon precipitation front from the southern slope of the Himalaya onto the Tibetan Plateau. In Korea the nested domain simulation (20 km) shows an encouraging performance with regard to capturing extreme precipitation episodes and the finer spatial distribution reflects the detailed geography of the Korean Peninsula. Over South America, RegCM captures the annual cycle of precipitation over Northeast Brazil and the South American Monsoon region, although the monsoon onset occurs too early in the model. Precipitation over the Amazon is not well captured, with too little precipitation associated with weak easterlies and reduced moisture transport into the interior of the continent. RegCM simulates the annual cycle of precipitation over Central America and the Caribbean fairly well; in particular, the complex spatial distribution of the Mid-Summer Drought, a decrease in precipitation that occurs during the middle of the rainy season in July and August, is better captured by RegCM than by the GCM. In addition, RegCM simulates the strength and position of the Caribbean low level jet, a mesoscale feature related to precipitation anomalies

Modern Integration Processes in the Asia-Pacific Region: the Formation of Trans-Regional Mega-Agreements

Full Text Available In the 21st century, especially in the last decade, new intercontinental integration projects appear on the global stage with a high potential for influencing the regional economic structure and at the same time bearing certain challenges for the international geo-economic and geo-political map of the world. Comprehensive new-generation inter-regional agreements are being formed, such as the TTP, the TTIP, the RCEP, the Comprehensive Economic and Trade Agreement between Canada and the EU (CETA, the Japan-EU Economic Partnership. The Asia-Pacific region has been an active participant in the creation and promotion of mega-regional trade agreements. Mega-regional trade agreements in the Asia-Pacific region, namely the TTP and the RCEP, are analyzed as mega-projects with an unprecedented scale of liberalization within the framework of the agreement that include provisions complementing the WTO framework or extending beyond it. There identified reasons for the emergence of mega-regional trade agreements and prospects for the implementation of these projects, as well as possible consequences for the international economic system. It is established that new trans-regional projects, providing certain advantages to the participating countries, simultaneously carry both opportunities and challenges for the world economy. The latter are associated with the threats of crowding the countries that do not take an active part in the integration processes out of the global chains of value creation as well as of the processes of international trade.

Bilingualism alters brain functional connectivity between "control" regions and "language" regions: Evidence from bimodal bilinguals.

Previous neuroimaging studies have revealed that bilingualism induces both structural and functional neuroplasticity in the dorsal anterior cingulate cortex (dACC) and the left caudate nucleus (LCN), both of which are associated with cognitive control. Since these "control" regions should work together with other language regions during language processing, we hypothesized that bilingualism may also alter the functional interaction between the dACC/LCN and language regions. Here we tested this hypothesis by exploring the functional connectivity (FC) in bimodal bilinguals and monolinguals using functional MRI when they either performed a picture naming task with spoken language or were in resting state. We found that for bimodal bilinguals who use spoken and sign languages, the FC of the dACC with regions involved in spoken language (e.g. the left superior temporal gyrus) was stronger in performing the task, but weaker in the resting state as compared to monolinguals. For the LCN, its intrinsic FC with sign language regions including the left inferior temporo-occipital part and right inferior and superior parietal lobules was increased in the bilinguals. These results demonstrate that bilingual experience may alter the brain functional interaction between "control" regions and "language" regions. For different control regions, the FC alters in different ways. The findings also deepen our understanding of the functional roles of the dACC and LCN in language processing.

Chinese regions frequently exchange materials, but regional differences in economic development create unbalanced flows of these resources. In this study, we examined energy by assessing embodied energy consumption to describe the energy-flow structure in China's seven regions. Based on multi-regional monetary input–output tables and energy statistical yearbooks for Chinese provinces in 2002 and 2007, we accounted for both direct and indirect energy consumption, respectively, and the integral input and output of the provinces. Most integral inputs of energy flowed from north to south or from east to west, whereas integral output flows were mainly from northeast to southwest. This differed from the direct flows, which were predominantly from north to south and west to east. This demonstrates the importance of calculating both direct and indirect energy flows. Analysis of the distance and direction traveled by the energy consumption centers of gravity showed that the centers for embodied energy consumption and inputs moved southeast because of the movements of the centers of the Eastern region. However, the center for outputs moved northeast because the movement of the Central region. These analyses provide a basis for identifying how regional economic development policies influence the embodied energy consumption and its flows among regions. - Highlights: • We integrated multi-regional input–output analysis with ecological network analysis. • We accounted for both direct and indirect energy consumption. • The centers of gravity for embodied energy flows moved southeast from 2002 to 2007. • The results support planning of energy consumption and energy flows among regions.

The impact of domestic trade on China's regional energy uses: A multi-regional input–output modeling

To systematically reveal how domestic trade impacts on China's regional energy uses, an interprovincial input–output modeling is carried out to address demand-derived energy requirements for the regional economies in 2007 based on the recently available data. Both the energy uses embodied in final demand and interregional trade are investigated from the regional and sectoral insights. Significant net transfers of embodied energy flows are identified from the central and western areas to the eastern area via interregional trade. Shanxi is the largest energy producer and interregional embodied energy deficit receiver, in contrast to Guangdong as the largest energy user and surplus receiver. By considering the impacts of interregional trade, the energy uses of most eastern regions increase remarkably. For instance, Shanghai, Hainan, Zhejiang, Beijing, Jiangsu and Guangdong have their embodied energy requirements 87.49, 19.97, 13.64, 12.60, 6.46 and 6.38 times of their direct energy inputs, respectively. In contrast, the embodied energy uses of some central and western regions such as Inner Mongolia, Shanxi, Xinjiang, Shaanxi and Guizhou decrease largely. The results help understand the hidden network linkages of interregional embodied energy flows and provide critical insight to amend China's current end-reduction-oriented energy policies by addressing the problem of regional responsibility transfer. - Highlights: • Demand-derived energy requirements for China's regional economies are addressed. • Significant interregional transfers of embodied energy flows are identified. • Energy surpluses are obtained by 19 regions and deficits by the other 11 regions. • The eastern regions should take more responsibility for reducing China's energy uses

Full Text Available This article sets out the conceptual framework and results of Regional Quality of Living indicators that were developed in order to benchmark European NUTS2 regions. Nine non-business-related indicators are constructed to support the goal of policy makers to improve the attractiveness of regions and cities for people or companies to settle in, and by doing so create economic growth. Each of the constructed indicators represents a pillar of the Quality of Living. The highest indicator scores are found for regions within Switzerland, Sweden, Norway and the Netherlands. Some countries show a wide divergence between regional scores. The southern regions of Italy and Spain, for example, have significantly lower scores than those in the north. In addition, capital city regions have better RQI scores. A positive correlation was found between the average RQI scores and both GDP per capita and weighted population density. Compared to GDP per capita, weighted population density has a modest influence on the RQI score. The European regions are divided into 11 clusters, based upon GDP per capita and weighted population density in order to benchmark a region with its peers.

Environmental risk assessment and analysis has a crucial role for guaranteeing the safety of the population, especially in intensive urbanized and industrialized areas, such as the Campania region (Italy). In Italy, since 2006, the human health risk assessment has become mandatory for contaminated soil and waters at contaminated sites. While traditional risk assessment procedures are usually run at site specific level (brownfields), with this work we would like to introduce a freshly developed method to assess risks at regional level by means of GIS, considering the hazard due to the presence in the environment of a contaminated media, the land use variability and the actual distribution of the population. 3535 top soils were collected across the whole Campania region (Italy) with a sampling density of 1 sample/4 km2. Samples were analyzed at ACME Analytical Lab. Ltd (Vancouver, Canada), to determine the concentration of 52 elements, with a combined methods of ICP-MS and ICP-ES following an aqua regia digestion. After a detailed statistical data analysis and geochemical mapping, we reclassified the interpolated maps of some potentially toxic elements (Sb, As, Be, Cd, Co, Cr, Hg, Ni, Pb, Se, Sn, Tl, V, Zn), in accordance with the Italian environmental law (D.Lgs 152/2006), on the base of the trigger and action limits (CSC) for human safety established by this latter. The obtained maps were summed up in the GIS environment in order to get a cumulative map of the potential hazard for the topsoils of Campania region. Considering that environmental risk for the population is strongly influenced by the exposure pathways followed by contaminants to reach the human target, in the case of Campania region we evaluated as relevant pathways both the soil/dust and food ingestion. Furthermore to consider the influence of the land use in the onset of the risk, each land use type was associated with a specific value of a Land Use Risk Coefficient (LURC) which is also dependent on

From Pixels to Region: A Salient Region Detection Algorithm for Location-Quantification Image

Directory of Open Access Journals (Sweden)

Mengmeng Zhang

2014-01-01

Full Text Available Image saliency detection has become increasingly important with the development of intelligent identification and machine vision technology. This process is essential for many image processing algorithms such as image retrieval, image segmentation, image recognition, and adaptive image compression. We propose a salient region detection algorithm for full-resolution images. This algorithm analyzes the randomness and correlation of image pixels and pixel-to-region saliency computation mechanism. The algorithm first obtains points with more saliency probability by using the improved smallest univalue segment assimilating nucleus operator. It then reconstructs the entire saliency region detection by taking these points as reference and combining them with image spatial color distribution, as well as regional and global contrasts. The results for subjective and objective image saliency detection show that the proposed algorithm exhibits outstanding performance in terms of technology indices such as precision and recall rates.

Family in historical and regional perspective

Full Text Available In this article author gives try to provide a frame suitable for researches of regional and multicultural characteristics of family, specially in Vojvodina region. Starting with the thesis that there is no perfect analytical model to be applied in investigation of regionalization and multiculturality, for the gap between monocultural and multicultural epistemology could not be bridged over, author is paying attention to the opportunities for regionalization to pervert in regionalism in the sense of ideology and policy that neglect specific regional needs of family. This dispels a negative consequences concerning the self development of the family as a very reason for regionalization to be accomplished. In spite of attractive ideas that regionalization is addressed to, regionalization of this kind realizes on the matrix above, of deciding 'in the people's name'. In this fashion regionalization is followed with the violence and confrontations as probable outcomes of changes within multicultural society. Exaggeration in emphasizing of differences. a s well as its neglecting, would cause more or less open confrontations and thus provide the causes of dissolution of the communities. In this context main problem is how family could retained its stability if it persists under the pressure of contrary forces concerning identity. This would be resolved only if identity is conceived as an open complex and ever unfinished on lay - in endless process of building. Regionalization in this sense of the term could be perceived as a defining of the proper game rules as well as it forceful adjustment and completion.

Physics of fully ionized regions

International Nuclear Information System (INIS)

Flower, D.

1975-01-01

In this paper the term fully ionised regions is taken to embrace both planetary nebulae and the so-called 'H II' regions referred to as H + regions. Whilst these two types of gaseous nebulae are very different from an evolutionary standpoint, they are physically very similar, being characterised by photoionisation of a low-density plasma by a hot star.

Distribution of microspheres to regions of dog lung compares well with regional flow of red blood cells

International Nuclear Information System (INIS)

Beck, K.C.; Rehder, K.

1986-01-01

Dorso-caudal areas of dog lungs are better perfused than ventral regions, independent of gravity. Could this be an artifact due to regional bias in lodging of MS. The costal surfaces of 5 isolated blood perfused left lungs of dogs [constant blood flow (F), Ppa, Ppv and Palv] were imaged (gamma camera) first after injection of 141 Ce-labeled MS (15 μ), then in 0.4 sec intervals after a bolus injection of 99 Tc-labeled red blood cells (RBC). Count rates were analyzed in 6 regions. Regional flow measured by MS (flowMS) is F times regional counts divided by total counts in the first image. Regional flow measured by RBC (flowRBC) is F times peak regional counts divided by peak total counts in the 0.4 sec images. The ratio flowMS/flow RBC was greater than 1.0 (P<0.001), suggesting a systematic difference between 1.0 (P<0.001), suggesting a systematic difference between flowMS and flow RBC. More importantly, there was no difference in flowMS/flow RBC among lung regions, allowing the authors to conclude there was no regional bias of flows

Cool transition region loops observed by the Interface Region Imaging Spectrograph

An important class of loops in the solar atmosphere, cool transition region loops, have received little attention mainly due to instrumental limitations. We analyze a cluster of these loops in the on-disk active region NOAA 11934 recorded in a Si IV 1402.8 Å spectral raster and 1400Å slit-jaw (SJ) images taken by the Interface Region Imaging Spectrograph. We divide these loops into three groups and study their dynamics, evolution and interaction.The first group comprises geometrically relatively stable loops, which are finely scaled with 382~626 km cross-sections. Siphon flows in these loops are suggested by the Doppler velocities gradually changing from -10 km/s (blue-shifts) in one end to 20 km/s (red-shifts) in the other. Nonthermal velocities from 15 to 25 km/s were determined. The obtained physical properties suggest that these loops are impulsively heated by magnetic reconnection occurring at the blue-shifted footpoints where magnetic cancellation with a rate of 1015 Mx/s is found. The released magnetic energy is redistributed by the siphon flows. The second group corresponds to two active footpoints rooted in mixed-magnetic-polarity regions. Magnetic reconnection in both footpoints is suggested by explosive-event line profiles with enhanced wings up to 200 km/s and magnetic cancellation with a rate of ~1015 Mx/s. In the third group, an interaction between two cool loop systems is observed. Mixed-magnetic polarities are seen in their conjunction area where explosive-event line profiles and magnetic cancellation with a rate of 3×1015 Mx/s are found. This is a clear indication that magnetic reconnection occurs between these two loop systems. Our observations suggest that the cool transition region loops are heated impulsively most likely by sequences of magnetic reconnection events.

HII regions are zones of ionized gas surrounding recently formed high-mass (OB-type) stars. They are among the brightest objects in the sky at radio wavelengths. HII regions provide a useful tool in constraining the Galactic morphological structure, chemical structure, and star formation rate. We describe the Southern HII Region Discovery Survey (SHRDS), an Australia Telescope Compact Array (ATCA) survey that discovered ~80 new HII regions (so far) in the Galactic longitude range 230 degrees to 360 degrees. This project is an extension of the Green Bank Telescope HII Region Discovery Survey (GBT HRDS), Arecibo HRDS, and GBT Widefield Infrared Survey Explorer (WISE) HRDS, which together discovered ~800 new HII regions in the Galactic longitude range -20 degrees to 270 degrees. Similar to those surveys, candidate HII regions were chosen from 20 micron emission (from WISE) coincident with 10 micron (WISE) and 20 cm (SGPS) emission. By using the ATCA to detect radio continuum and radio recombination line emission from a subset of these candidates, we have added to the population of known Galactic HII regions.

Regional development is very closely related to a region and its competitive advantages which affect the competitiveness of the region. The regional development is influenced by many factors that act differently depending on the region. To ensure the effective and harmonized regional development, the systematic approach is needed. Every region is unique and differs from the other by the level of economic development, living standards of its inhabitants, unemployment rate and by employment possibilities. Regional policy is a strategic investment policy which focuses on all regions and cities in the European Union. The aim is to boost economic growth and to improve the quality of people’s lives. Solidarity is the main feature of the policy, because policy focuses on support for less developed regions. A fundamental aspect of regional development is to reduce disparities between the regions and cities. The paper focuses on the analysis of regional development of Slovakia. The intention is to follow the logical continuity of the article’s parts, the correctness and the adequacy of information and data. First part is focused on the definition of the regional policy and regional development. Important task is to identify the differences between European policies - regional, structural and cohesion policy. This section is prepared by using the analytical methods - the analysis, the casual and historical analysis. This part is based on literature review. The empirical part is based on statistics and secondary analysis which were aimed to analyse the regional development and effectiveness of its planning in the Slovak Republic. The question of this article is whether it is possible to plan the regional development by application of the plan for economic and social development, called the Municipal Development Plan.

This document presents: the end-use energy consumption, the sectorial statuses (residential, tertiary sector, industry, agriculture, transports), the energy production and the renewable energy sources in Aquitaine region. Details are given in separate files at the end of the document for the 5 departements of Aquitaine (Dordogne, Gironde, Landes, Lot-et-Garonne, Pyrennees Atlantiques). (J.S.)

Regional differences in the CO_2 emissions of China's iron and steel industry: Regional heterogeneity

International Nuclear Information System (INIS)

Xu, Bin; Lin, Boqiang

2016-01-01

Identifying the key influencing factors of CO_2 emissions in China's iron and steel industry is vital for mitigating its emissions and formulating effective environmental protection measures. Most of the existing researches utilized time series data to investigate the driving factors of the industry's CO_2 emission at the national level, but regional differences have not been given appropriate attention. This paper adopts provincial panel data from 2000 to 2013 and panel data models to examine the key driving forces of CO_2 emissions at the regional levels in China. The results show that industrialization dominates the industry's CO_2 emissions, but its effect varies across regions. The impact of energy efficiency on CO_2 emissions in the eastern region is greater than in the central and western regions because of a huge difference in R&D investment. The influence of urbanization has significant regional differences due to the heterogeneity in human capital accumulation and real estate development. Energy structure has large potential to mitigate CO_2 emissions on account of increased R&D investment in energy-saving technology and expanded clean energy use. Hence, in order to effectively achieve emission reduction, local governments should consider all these factors as well as regional heterogeneity in formulating appropriate mitigation policies. - Highlights: • We explore the driving forces of CO_2 emissions in China's steel industry. • Industrialization dominates CO_2 emissions in the iron and steel industry. • Energy structure has large potential to mitigate CO_2 emissions in the steel industry. • The influence of urbanization has significant regional differences.

The regional approach and regional studies method in the process of geography teaching

We define the regional approach as a manner of relations among the global trends of development of the "Society-man-nature" system and the local differentiating level of knowledge. Conditionally, interactions interlace under the influence of the character of Geography as a science, education, approaches, goals and teaching methods. Global, national and local development differentiates in three concentric circles at the level of knowledge. It is determined as a conception of modern, complex and effective mechanism for young people, through which knowledge develops in regional historical and cultural perspective; self-consciousness for socio-economic and cultural integration is formed as a part of the. historical-geographical image of the native land. This way an attitude to the. native land is formed as a connecting construct between patriotism to the motherland and the same in global aspect. The possibility for integration and cooperation of the educative geographical content with all the local historical-geographical, regional, profession orientating, artistic, municipal and district institutions, is outlined. Contemporary geographical education appears to be a powerful and indispensable mechanism for organization of human sciences, while the regional approach and the application of the regional studies method stimulate and motivate the development and realization of optimal capacities for direct connection with the local structures and environments.

Full Text Available Este trabalho analisou o processo de formação regional do Brasil, os desequilíbrios existentes entre as regiões e as perspectivas futuras. Teve como proposta básica analisar o possível processo de convergência de renda das regiões brasileiras, utilizando o conceito de gap tecnológico. Segundo esse conceito, os desequilíbrios regionais são o resultado de diferentes taxas de desenvolvimento econômico, que, por sua vez, resultam de diferentes níveis de desenvolvimento tecnológico, os quais, por fim, são consequências de condições históricas, sociais e culturais específicas de cada região. Dessa forma, pressupôs-se a existência de relação positiva entre nível de desenvolvimento tecnológico, dependência tecnológica, dependência econômica, nível de desenvolvimento econômico e convergência de renda. Os resultados mostram que, em relação à possibilidade de as regiões e os estados menos desenvolvidos realizarem o catching up com aqueles mais desenvolvidos, as variáveis que representam tanto a geração quanto a apropriação de novas tecnologias são significativas e diretamente relacionadas com o produto. Dessa forma, pode-se afirmar que o catching up seria possível caso houvesse um maior investimento no processo de desenvolvimento e apropriação de novas tecnologias por parte dos governos regionais.This research developed an analysis on the regional imbalances at the Brazilian economy, the historic formation of the regions and perspectives.

Regional Ocean Data Assimilation

KAUST Repository

Edwards, Christopher A.

2015-01-03

This article reviews the past 15 years of developments in regional ocean data assimilation. A variety of scientific, management, and safety-related objectives motivate marine scientists to characterize many ocean environments, including coastal regions. As in weather prediction, the accurate representation of physical, chemical, and/or biological properties in the ocean is challenging. Models and observations alone provide imperfect representations of the ocean state, but together they can offer improved estimates. Variational and sequential methods are among the most widely used in regional ocean systems, and there have been exciting recent advances in ensemble and four-dimensional variational approaches. These techniques are increasingly being tested and adapted for biogeochemical applications.

Cloaks with multiple invisible regions

International Nuclear Information System (INIS)

Luo, Yang; Zhu, Shouzheng; He, Lianxing; Wang, Yu

2011-01-01

This paper proposes a general method of extending the effective invisible regions for both the shell-like interior cloak and the complementary media exterior cloak, without affecting their original cloaking regions. The proposed method is based on layered spatial mapping instead of the intact mapping. Certain interior or exterior invisible regions can be obtained by properly using a compressed or folded transformation in each space layer. Therefore, the proposal enables the as-designed cloaks to provide multiple invisible regions of different types simultaneously. Thus objects can be hidden in the interior cavity and/or in the exterior space, or even be embedded between the cloaking shells

2011-03-01

Full Text Available This paper deals with basic principles of self-regulation of tourist complexes as regional socio-economic systems on the example of Sverdlovsk region. These include the principles of goal setting and the necessary diversity of economic entropy: in this case, these are important for the tourism industry and the human and natural resource and ecological potential. Is it shown how a tourist complex influences the socio-economic development of regional economic systems. In particular, tourism influences some of migration processes. Tourism development strategy in the Russian Federation at the tourist center level is analyzed. The need to develop such a strategy is due to the transition to market relations and, as a consequence, complexity of governmental regulation. It is substantiated that Sverdlovsk region is a subject to following strategy and might be successful in various sectors of tourism: business and congress and exhibition, urban entertainment, family and shopping tourism, sports, medical and recreational tourism.

NONE

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.

Regional Branding: Building Brand Value

Full Text Available Regional branding is one of several ways to promote rural regions and support development of socially, culturally and environmentally oriented economies in areas that are interesting due to their natural and cultural heritage. The article attempts to review the conceptual and theoretical underpinnings of branding as conveyed by leading authors in the marketing field. The aim of this paper is to define brand as a broad complex of variables, which are used in building of its identity as a basis for creating value proposition and the position of a brand. Article briefly describes the most comprehensive labeling system for regional products at the micro-regional level is the one guaranteed by Association of Regional Brands (ARB. The main contribution of this article is a theoretical model of strategic management of a regional brand, which captures the interdependence of the individual steps of brand building as well as stakeholders. The starting point for building of brand value is a strategic analysis of the brand, including analysis of customer and competitors. The analysis of external factors is followed by analysis of the brand itself. The resulting relationship between the brand and the customer is based on value proposition representing benefits (functional, emotional, self‑expression. The concept of total product is connected with the concept of total brand and it is offered to the customer as a regional product. Finally it suggests possibilities for further research.

Regional Courts as Judicial Brakes?

Directory of Open Access Journals (Sweden)

Metcalf Katrin Nyman

2017-12-01

Full Text Available The article examines how regional integration courts can act as judicial brakes, at a time when “constitutional coups” – leaders staying in power past constitutional time limits or other forms of actions against the spirit if not always the letter of the constitution – are alarmingly common. The article discusses how regional courts can be used to modify or protect national rule of law and the constitutional order from the outside (i.e. from the regional integration aspect and the extent to which this can be valid particularly to promote a uniform interpretation and application of human rights. Although this trend is visible in Europe, it is more striking, because less expected, on other continents, in particular Africa and the Americas, where the developments take place in less than perfect democratic environments. The article contains evidence from cases dealt with in the various regional courts, supporting that a system of political and judicial oversight, especially in regions with weak or fragile democratic systems, can be a useful addition to national judicial or other mechanisms of protection of rule of law and control of the executive. Action by regional courts helps defeat perceptions of majoritarian politics, which in many countries allow for the winner to take all. Under a system of regional oversight, states become aware of the limits they themselves have set and citizens become aware of their possibilities to challenge political power.

Venus - Phoebe Region

This Magellan radar image is of part of the Phoebe region of Venus. It is a mosaic of parts of revolutions 146 and 147 acquired in the first radar test on Aug. 16, 1990. The area in the image is located at 291 degrees east longitude, 19 degrees south latitude. The image shows an area 30 kilometers (19.6 miles) wide and 76 km (47 miles) long. On the basis of Pioneer Venus and Arecibo data, it is known that two major rift zones occur in southern Phoebe Regio and that they terminate at about 20 to 25 degrees south latitude, about 2,000 km (1,240 miles) apart. This image is of an area just north of the southern end of the western rift zone. The region is characterized by a complex geologic history involving both volcanism and faulting. Several of the geologic units show distinctive overlapping or cross cutting relationships that permit identification and separation of geologic events and construction of the geologic history of the region. The oldest rocks in this image form the complexly deformed and faulted, radar bright, hilly terrain in the northern half. Faults of a variety of orientations are observed. A narrow fault trough (about one-half to one km (three tenths to six tenths of a mile) wide is seen crossing the bright hills near the lower part in the middle of the image. This is one of the youngest faults in the faulted, hilly unit as it is seen to cut across many other structures. The fault trough in turn appears to be embayed and flooded by the darker plains that appear in the south half of the image. These plains are interpreted to be of volcanic origin. The dark plains may be formed of a complex of overlapping volcanic flows. For example, the somewhat darker region of plains in the lower left (southwest) corner of the image may be a different age series of plains forming volcanic lava flows. Finally, the narrow bright line crossing the image in its lower part is interpreted to be a fault which cross cuts both plains units and is thus the youngest event in

Regional collaboration has been identified as a potential facilitator of public health preparedness efforts. The Urban Area Security Initiative (UASI) grant program, administered by the Federal Emergency Management Agency (FEMA) since 2003, has provided 64 high-risk metropolitan areas funding to enhance their regional preparedness capabilities. This study describes informal and formal regional collaboration infrastructure, as well as regional collaboration-related activities and assessment methods, in FFY2010 UASI regions. A cross-sectional online survey was administered via Survey Monkey from September through December 2013. Points of contact from FFY2010 funded UASI metropolitan areas completed the survey, with a response rate of 77.8% (n=49). Summary statistics were calculated to describe the current informal and formal regional collaboration infrastructure. Additionally, the cross-sectional survey collected rates of agreement with 8 collaborative preparedness statements at 3 time points. The survey found that UASI regions are engaging in collaborative activities and investments to build capabilities, with most collaboration occurring in the prevention, protection, and response mission areas. Collaborative relationships in preparedness among emergency managers and municipal chief executive officers improved during the FFY2010 UASI performance period compared to the pre-UASI award period, with lasting effects. The majority of UASI regions reported conducting independent assessments of capabilities and their measurement at the UASI region level. Urban areas that received a FFY2010 UASI grant award are engaging in collaborative activities and have established interjurisdictional relationships in preparedness. The use of grant funds to encourage collaboration in preparedness has the potential to leverage limited resources and promote informed investments.

Full Text Available Building upon insights from earlier investigations of innovation collaboration from a regional perspective as well as the triple helix perspective, local/regional innovation systems and open innovation approaches, this study explores whether cooperation between firms, universities and government increases the intensity of innovation equally for the capital city and peripheral regions. We investigate whether firms located in the capital region benefit more from public support, cooperation with universities, and cooperation with different stakeholders than firms located in peripheral regions. Using logistic binary regressions, we find that capital region firms are generally not more innovative than those located elsewhere. We also find no effect on innovation from cooperation with universities, although public support is related to engagement in product and process innovations. Our results warn against simple applications of triple helix and open innovation approaches, as many forms of collaboration seem to have little impact on innovation, regardless of regional context.

Regional Convergence of Income: Spatial Analysis

Vera Ivanovna Ivanova

2014-12-01

Full Text Available Russia has a huge territory and a strong interregional heterogeneity, so we can assume that geographical factors have a significant impact on the pace of economic growth in Russian regions. Therefore the article is focused on the following issues: 1 correlation between comparative advantages of geographical location and differences in growth rates; 2 impact of more developed regions on their neighbors and 3 correlation between economic growth of regions and their spatial interaction. The article is devoted to the empirical analysis of regional per capita incomes from 1996 to 2012 and explores the dynamics of the spatial autocorrelation of regional development indicator. It is shown that there is a problem of measuring the intensity of spatial dependence: factor value of Moran’s index varies greatly depending on the choice of the matrix of distances. In addition, with the help of spatial econometrics the author tests the following hypotheses: 1 there is convergence between regions for a specified period; 2 the process of beta convergence is explained by the spatial arrangement of regions and 3 there is positive impact of market size on regional growth. The author empirically confirmed all three hypotheses

A preliminary regional assessment of earthquake-induced landslide susceptibility for Vrancea Seismic Region

In seismically-active regions, earthquakes may trigger landslides enhancing the short-to-long term slope denudation and sediment delivery and conditioning the general landscape evolution. Co-seismic slope failures present in general a low frequency - high magnitude pattern which should be addressed accordingly by landslide hazard assessment, with respect to the generally more frequent precipitation-triggered landslides. The Vrancea Seismic Region, corresponding to the curvature sector of the Eastern Romanian Carpathians, represents the most active sub-crustal (focal depth > 50 km) earthquake province of Europe. It represents the main seismic energy source throughout Romania with significant transboundary effects recorded as far as Ukraine and Bulgaria. During the last 300 years, the region featured 14 earthquakes with M>7, among which seven events with magnitude above 7.5 and three between 7.7 and 7.9. Apart from the direct damages, the Vrancea earthquakes are also responsible for causing numerous other geohazards, such as ground fracturing, groundwater level disturbances and possible deep-seated landslide occurrences (rock slumps, rock-block slides, rock falls, rock avalanches). The older deep-seated landslides (assumed to have been) triggered by earthquakes usually affect the entire slope profile. They often formed landslide dams strongly influencing the river morphology and representing potential threats (through flash-floods) in case of lake outburst. Despite the large potential of this research issue, the correlation between the region's seismotectonic context and landslide predisposing factors has not yet been entirely understood. Presently, there is a lack of information provided by the geohazards databases of Vrancea that does not allow us to outline the seismic influence on the triggering of slope failures in this region. We only know that the morphology of numerous large, deep-seated and dormant landslides (which can possibly be reactivated in future

Full Text Available This population-based study sought to extend knowledge on factors explaining regional differences in type 2 diabetes mellitus medication patterns in Germany.Individual baseline and follow-up data from four regional population-based German cohort studies (SHIP [northeast], CARLA [east], HNR [west], KORA [south] conducted between 1997 and 2010 were pooled and merged with both data on regional deprivation and regional health care services. To analyze regional differences in any or newer anti-hyperglycemic medication, medication prevalence ratios (PRs were estimated using multivariable Poisson regression models with a robust error variance adjusted gradually for individual and regional variables.The study population consisted of 1,437 people aged 45 to 74 years at baseline, (corresponding to 49 to 83 years at follow-up with self-reported type 2 diabetes. The prevalence of receiving any anti-hyperglycemic medication was 16% higher in KORA (PR 1.16 [1.08-1.25], 10% higher in CARLA (1.10 [1.01-1.18], and 7% higher in SHIP (PR 1.07 [1.00-1.15] than in HNR. The prevalence of receiving newer anti-hyperglycemic medication was 49% higher in KORA (1.49 [1.09-2.05], 41% higher in CARLA (1.41 [1.02-1.96] and 1% higher in SHIP (1.01 [0.72-1.41] than in HNR, respectively. After gradual adjustment for individual variables, regional deprivation and health care services, the effects only changed slightly.Neither comprehensive individual factors including socioeconomic status nor regional deprivation or indicators of regional health care services were able to sufficiently explain regional differences in anti-hyperglycemic treatment in Germany. To understand the underlying causes, further research is needed.

Obesity and Regional Immigrant Density.

Emerson, Scott D; Carbert, Nicole S

2017-11-24

Canada has an increasingly large immigrant population. Areas of higher immigrant density, may relate to immigrants' health through reduced acculturation to Western foods, greater access to cultural foods, and/or promotion of salubrious values/practices. It is unclear, however, whether an association exists between Canada-wide regional immigrant density and obesity among immigrants. Thus, we examined whether regional immigrant density was related to obesity, among immigrants. Adult immigrant respondents (n = 15,595) to a national population-level health survey were merged with region-level immigrant density data. Multi-level logistic regression was used to model the odds of obesity associated with increased immigrant density. The prevalence of obesity among the analytic sample was 16%. Increasing regional immigrant density was associated with lower odds of obesity among minority immigrants and long-term white immigrants. Immigrant density at the region-level in Canada may be an important contextual factor to consider when examining obesity among immigrants.

Moment Magnitude Calibration for the Eastern Mediterranean Region from Broadband Regional Coda Envelopes

2003-07-17

The following is an overview of results from ROA01-32 that focuses on an empirical method of calibrating stable seismic source moment-rate spectra derived from regional coda envelopes using broadband stations. The main goal was to develop a regional magnitude methodology that had the following properties: (1) it is tied to an absolute scale and is thus unbiased and transportable; (2) it can be tied seamlessly to the well-established teleseismic and regional catalogs; (3) it is applicable to small events using a sparse network of regional stations; (4) it is flexible enough to utilize S{sub n}-coda, L{sub g}-coda, or P-coda, whichever phase has the best signal-to-noise ratio. The results of this calibration yield source spectra and derived magnitudes that were more stable than any other direct-phase measure to date. Our empirical procedure accounted for all propagation, site, and S-to-coda transfer function effects. The resultant coda-derived moment-rate spectra were used to provide traditional band-limited magnitude (e.g., M{sub L}, m{sub b} etc.) as well as an unbiased, unsaturated magnitude (moment magnitude, M{sub w}) that is tied to a physical measure of earthquake size (i.e., seismic moment). We validated our results by comparing our coda-derived moment estimates with those obtained from long-period waveform modeling. We first tested and validated the method using events distributed along the Dead Sea Rift (e.g., Mayeda et al., 2003). Next, we tested the transportability of the method to earthquakes distributed across the entire country of Turkey and validated our results using seismic moments of over 50 events that had been previously waveform modeled using the method of Dreger and Helmberger, (1993). In both regions we demonstrated that the interstation magnitude scatter was significantly reduced when using the coda-based magnitudes (i.e., M{sub w}(coda) and m{sub b}(coda)). Once calibrated, the coda-derived source spectra provided stable, unbiased magnitude

The imbalances in the levels of development of various territorial units of Serbia (regional disproportions are the consequence of many structural disharmonies, material limitations, and problems with populationstructure, during many years, all worsened by political and economic events at the end of the twentieth century. Also, in this paper we point out the main characteristics of undeveloped regions, the criteria with which we can define them, and a typology of the municipalities inside each such region.

Full Text Available As the budgets of the European Union (EU become tighter, the questions about the effectiveness of EU’s expenditure, especially the most important parts such as Cohesion policy, are hotly debated. The aim of this paper is to examine whether the presence of social attitudes may influence the effectiveness of EU budget expenditure, measured by the level of regional inequalities. The analysis starts by focusing on individuals’ attitudes towards income from their own effort and income which is derived from other people’s effort, having in mind that individual actions depend on their attitudes. The next step establishes the link between the income from other people’s effort with the re-distributive dimension of the EU budget, considering that different attitudes among individuals in the EU could lead to significant differences in effectiveness of this redistributive policy among European regions and, consequently, diverse regional inequalities. Empirical research uses data for 27 EU countries observed over two waves of European Value Surveys: 1999-2000 (Wave 1 and 2008–2009 (Wave 2. The results indicate a significant role of social attitudes for regional inequalities, which raises the question of the appropriateness of simplification and uniform regional policy instruments in solving EU regional problems.

Full Text Available In the article, the authors substantiate the need to consider the regional economic and other conditions when carrying out various essential transformations in the national economy of the country. We have argued the importance of new industrialization for overcoming the technological lag of the country and its regions and for supporting the large-scale structural transformations. We have proved that the complex set of the interconnected concepts and the theories of macro- and microlevels may be the theoretical platform for the paradigm of new industrialization. These are the theory of economic growth, the theory of the modernization of the economy, the theory of the change of technological ways during the industrial revolutions, theories of innovative development, developments in the field of the institutional theory. The authors have shown that the transition to new industrialization is the fundamental historical pattern for the majority of the countries of the world, including industrially developed ones. The purpose of the article is to identify the brightest tendencies and features of the development of the Ural macro-region in the years of market reforms as well as the definition of the strategic transformations in the context of the formation of new industrialization. The hypothesis of the research assumes that the revealed regional features of the Ural macroregion’s economic development are the prerequisites of its development as the centre of the modernization of the Russian economy. On the basis of the analysis of three groups of statistic data for the twenty-five year period of liberal and monetary reforms, the brightest tendencies and features of the development of the Ural macro-region are revealed. We have emphasized that the Ural macro-region has managed to keep its historically developed code — the industrial model of the economy, which have been developing for many decades.

North American Regional Report

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.

Alligator Rivers Region

International Nuclear Information System (INIS)

1992-01-01

An introduction to the Alligator Rivers Region is presented. It contains general information regarding the physiography, climate, hydrology and mining of the region. The Alligator Rivers Region is within an ancient basin, the Pine Creek Geosyncline, which has an area of approximately 66000 km 2 . The Geosyncline has a history of mineral exploitation dating back to 1865, during which time 16 metals have been extracted (silver, arsenic, gold, bismuth, cadmium, cobalt, copper, iron, manganese, molybdenum, lead, tin, tantalum, uranium, tungsten, zinc). Uranium exploration in the Pine Creek Geosyncline was stimulated by the discovery in 1949 of secondary uranium mineralisation near Rum June, 70 km south-east of Darwin. This was followed by a decade of intense exploration activity resulting in the discoveries of economic uranium ore bodies at Rum Jungle and in the upper reaches of the South Alligator River Valley. All the known major uranium deposits of the East Alligator River uranium field have been discovered since 1969. The present known resources of the Geosyncline are approximately 360 000 tonnes of contained U 3 O 8 . 2 refs., 2 figs., 1 tab

This paper proposes that strengthening regional capabilities for formulating and implementing arms control and confidence-building measures is a tangible method of enhancing regional security. It discusses the importance of developing a regional infrastructure for arms control and confidence building and elucidates the role of technology in facilitating regional arms control and confidence-building agreements. In addition, it identifies numerous applications for regional cooperative monitoring in the areas of arms control, resource management, international commerce and disaster response. The Cooperative Monitoring Center at Sandia National Laboratories, whose aim is to help individual countries and regions acquire the tools they need to develop their own solutions to regional problems, is discussed briefly. The paper ends with recommendations for establishing regional cooperative monitoring centers

Regional Diversity and Diversification in Mammals.

Science.gov (United States)

Machac, Antonin; Graham, Catherine H

2017-01-01

The effects of regional diversity on diversification remain controversial. The classic hypothesis that diversification decelerates as regional diversity increases has been recently revived. Yet, there is little geographic evidence for slower diversification across regions of high diversity, and diversity is often thought to promote diversification through its effects on ecological divergence and speciation. Here, we use the newest phylogeny for mammals (4,990 species) and two different methods to test the effects of regional diversity on diversification. We find that regions of high diversity are dominated by expanding clades that are far from their estimated carrying capacities. Regions of low diversity host clades that are small and mostly saturated. These results were supported across mammals and their six largest orders. They were corroborated by the two methods when controlling for clade relatedness, clade nestedness, and clade size. Together, these results reject the hypothesis that high geographic concentration of mammals effectively suppresses their further diversification. Instead, highly diverse regions (especially the tropics) seem to act as the engine of mammalian richness.

The regional seas programme of UNEP

Energy Technology Data Exchange (ETDEWEB)

Bliss-Guest, P.A. (United Nations Environment Programme, Geneva, Switzerland); Keckes, S.

1982-04-01

The 1972 United Nations Conference on the Human Environment (Stockholm) outlined a ''master plan'' for protecting the world's environment which linked environmental assessment, environmental management, and supporting measures, as basic and inseparable elements - also recognizing the advantages of a regional approach in contributing to the solution of global problems. The development of UNEP's Regional Seas Programme, since the Action Plan for the Mediterranean was adopted in 1975, demonstrates that the basic concepts formulated at Stockholm can effectively foster regional cooperation among interested States, and that such cooperation can and does benefit greatly from the support of the United Nations as a whole. The viability of any long-term regional programme lies with the political and financial commitment of the Governments concerned. Within the UNEP Regional Seas Programme this commitment is usually formalized through binding regional legal agreements, and is manifested concretely through an agreed set of activities that are revised periodically by the Governments involved. It is expected that these activities will be adquately supported by financial resources put at the disposal of each of the regional programmes primarily by the Governments concerned.

This paper presents a number of techniques that can be used to assess environmental impacts on a regional scale. Regional methodologies have been developed which examine impacts upon aquatic and terrestrial biota in regions through consideration of changes in land use, land cover, air quality, water resource use, and water quality. Techniques used to assess long-range atmospheric transport, water resources, effects on sensitive forest and animal species, and impacts on man are presented in this paper, along with an optimization approach which serves to integrate the analytical techniques in an overall assessment framework. A brief review of the research approach and certain modeling techniques used within one regional studies program is provided. While it is not an all inclusive report on regional analyses, it does present an illustration of the types of analyses that can be performed on a regional scale

We propose a method to study solar magnetic regions in the solar interior with the principle of optical holography. A magnetic region in the solar interior scatters the solar background acoustic waves. The scattered waves and background waves could form an interference pattern on the solar surface. We investigate the feasibility of detecting this interference pattern on the solar surface, and using it to construct the three-dimensional scattered wave from the magnetic region with the principle of optical holography. In solar acoustic holography, the background acoustic waves play the role of reference wave; the magnetic region plays the role of the target object; the interference pattern, acoustic power map, on the solar surface plays the role of the hologram.

Molecular speciation of phosphorus in organic amendments and amended soils using nuclear magnetic resonance and X-ray absorption spectroscopies

International Nuclear Information System (INIS)

Ajibove, B.

2007-01-01

Characterization of phosphorus (P) in organic amendments is essential for environmentally sustainable fertilization of agricultural soils. The sequential chemical extraction (SCE) technique commonly used for P characterization does not provide any direct molecular information about P species. Studies were conducted to characterize P species in organic amendments and amended soils at a molecular level. The SCE was used to fractionate P in organic amendments including biosolids, hog, dairy and beef cattle manures, and poultry litter. The extracts were analyzed for total P and P species using inductively coupled plasma - optical emission spectroscopy (ICP-OES) and solution 31 P nuclear magnetic resonance (NMR) spectroscopy, respectively. The relative proportions of P species in intact organic amendments and residues after each extraction, and calcareous soils amended with organic amendments and monoammonium phosphate (MAP) were estimated using the synchrotron-based P 1s X-ray absorption near edge structure (XANES) spectroscopy. The solution 31 P NMR provided a detailed characterization of organic P in the non-labile NaOH and HCl fractions of organic amendments, but was limited in characterizing the labile fractions of most of these organic amendments due to their proneness to alkaline hydrolysis. The XANES analysis, however, identified the actual chemical species constituting the labile P that was only characterized as inorganic P or orthophosphates by sequential extraction and solution 31 P NMR. In the amended Vertisolic and Chernozemic soils, XANES analysis estimated 'soluble and adsorbed P' as the dominant P species. For the Vertisolic soil, both the unamended and soil amended with biosolids and MAP contained hydroxyapatite (HAP). In addition, soil amended with biosolids, hog and dairy manures contained β-tricalcium phosphate (TRICAL), a more soluble CaP than HAP. TRICAL was found in all amended soils except in that amended with hog manure, while HAP was present

Spatial variability of soil properties is relevant for identifying those zones with physical degradation. In this sense, one has to face the problem of identifying the origin and distribution of spatial variability patterns (Brouder et al., 2001; Millán et al., 2012). The objective of the present work was to quantify the spatial structure of soil penetrometer resistance (PR) collected from a transect data consisted of 221 points equidistant. In each sampling, readings were obtained from 0 cm till 70 cm of depth, with an interval of 5 cm (Pérez, 2012). The study was conducted on a Vertisol (Typic Hapludert) dedicated to sugarcane (Saccharum officinarum L.) production during the last sixty years (Pérez et al., 2010). Recently, scaling approach has been applied on the determination of the scaling data properties (Tarquis et al., 2008; Millán et al., 2012; Pérez, 2012). We focus in the Hurst analysis to characterize the data variability for each depth. Previously a detrended analysis was conducted in order to better study de intrinsic variability of the series. The Hurst exponent (H) for each depth was estimated showing a characteristic pattern and differentiating PR evolution in depth. References Brouder, S., Hofmann, B., Reetz, H.F., 2001.

2012-01-01

The Health Systems in Transition (HiT) profiles are country-based reports that provide a detailed description of a health system and of policy initiatives in progress or under development. This HiT is one of the first to be written on a subnational level of government and focuses on the Veneto Region of northern Italy. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. The Veneto Region is one of Italy's richest regions and the health of its resident population compares favourably with other regions in Italy. Life expectancy for both men and women, now at 79.1 and 85.2 years, respectively, is slightly higher than the national average, while mortality rates are comparable to national ones. The major causes of death are tumours and cardiovascular diseases. Under Italy's National Health Service, the organization and provision of health care is a regional responsibility and regions must provide a nationally defined (with regional input) basic health benefit package to all of their citizens; extra services may be provided if budgets allow. Health care is mainly financed by earmarked central and regional taxes, with regions receiving their allocated share of resources from the National Health Fund. Historically, health budget deficits have been a major problem in most Italian regions, but since the early 2000s the introduction of efficiency measures and tighter procedures on financial management have contributed to a significant decrease in the Veneto Regions health budget deficit.The health system is governed by the Veneto Region government (Giunta) via the Departments of Health and Social Services, which receive technical support from a single General Management Secretariat.

Monetary policy and regional output in Brazil

Directory of Open Access Journals (Sweden)

Rafael Rockenbach da Silva Guimarães

2014-03-01

Full Text Available This work presents an analysis of whether the effects of the Brazilian monetary policy on regional outputs are symmetric. The strategy developed combines the techniques of principal component analysis (PCA to decompose the variables that measure regional economic activity into common and region-specific components and vector autoregressions (VAR to observe the behavior of these variables in response to monetary policy shocks. The common component responds to monetary policy as expected. Additionally, the idiosyncratic components of the regions showed no impact of monetary policy. The main finding of this paper is that the monetary policy responses on regional output are symmetrical when the regional output decomposition is performed, and the responses are asymmetrical when this decomposition is not performed. Therefore, performing the regional output decomposition corroborates the economic intuition that monetary policy has no impact on region-specific issues. Once monetary policy affects the common component of the regional economic activity and does not impact its idiosyncratic components, it can be considered symmetrical.

Full Text Available Abstract Background Among European countries, Italy is one of the countries where regional health disparities contribute substantially to socioeconomic health disparities. In this paper, we report on regional differences in self-reported poor health and explore possible determinants at the individual and regional levels in Italy. Methods We use data from the "Indagine Multiscopo sulle Famiglie", a survey of aspects of everyday life in the Italian population, to estimate multilevel logistic regressions that model poor self-reported health as a function of individual and regional socioeconomic factors. Next we use the causal step approach to test if living conditions, healthcare characteristics, social isolation, and health behaviors at the regional level mediate the relationship between regional socioeconomic factors and self-rated health. Results We find that residents living in regions with more poverty, more unemployment, and more income inequality are more likely to report poor health and that poor living conditions and private share of healthcare expenditures at the regional level mediate socioeconomic disparities in self-rated health among Italian regions. Conclusion The implications are that regional contexts matter and that regional policies in Italy have the potential to reduce health disparities by implementing interventions aimed at improving living conditions and access to quality healthcare.

Research objective is the justification of the need of activization of the state policy on Euro-regional cooperation in the sphere of the interstate regional governance. During the research it is recognized that the realization of the state policy on the basis of the considered principles, tools, functions, factors and methods has to execute a main objective of the interstate regional control which is exercised in the sphere of Euro-regional cooperation and to promote adjustment of close mutually beneficial relations of Ukraine and neighboring states, to increase competitiveness of the Ukrainian territories and the most effective use of capacity of the Ukrainian regions in the course of activity of Euro-regions. Finally, such state policy has to be focused on the maintenance of the sufficient standard of living of the population, on ensuring integrity and unity of the social and economic space of the country, on formation of the conditions of sustainable and industrial and innovative development of regions, which will provide its harmonious integration into the European environment.

Open magnetic fields in active regions

Soft X-ray images and magnetograms of several active regions and coronal holes are examined which support the interpretation that some of the dark X-ray gaps seen between interconnecting loops and inner cores of active regions are foot points of open field lines inside the active regions. Characteristics of the investigated dark gaps are summarized. All the active regions with dark X-ray gaps at the proper place and with the correct polarity predicted by global potential extrapolation of photospheric magnetic fields are shown to be old active regions, indicating that field opening is accomplished only in a late phase of active-region development. It is noted that some of the observed dark gaps probably have nothing in common with open fields, but are either due to the decreased temperature in low-lying portions of interconnecting loops or are the roots of higher and less dense or cooler loops.

Ethanol demand in Brazil: Regional approach

Freitas, Luciano Charlita de; Kaneko, Shinji

2011-01-01

Successive studies attempting to clarify national aspects of ethanol demand have assisted policy makers and producers in defining strategies, but little information is available on the dynamic of regional ethanol markets. This study aims to analyze the characteristics of ethanol demand at the regional level taking into account the peculiarities of the developed center-south and the developing north-northeast regions. Regional ethanol demand is evaluated based on a set of market variables that include ethanol price, consumer's income, vehicle stock and prices of substitute fuels; i.e., gasoline and natural gas. A panel cointegration analysis with monthly observations from January 2003 to April 2010 is employed to estimate the long-run demand elasticity. The results reveal that the demand for ethanol in Brazil differs between regions. While in the center-south region the price elasticity for both ethanol and alternative fuels is high, consumption in the north-northeast is more sensitive to changes in the stock of the ethanol-powered fleet and income. These, among other evidences, suggest that the pattern of ethanol demand in the center-south region most closely resembles that in developed nations, while the pattern of demand in the north-northeast most closely resembles that in developing nations. - Research highlights: → Article consists of a first insight on regional demand for ethanol in Brazil. → It proposes a model with multiple fuels, i.e., hydrous ethanol, gasohol and natural gas. → Results evidence that figures for regional demand for ethanol differ amongst regions and with values reported for national demand. → Elasticities for the center-south keep similarities to patterns for fuel demand in developed nations while coefficients for the north-northeast are aligned to patterns on developing countries.

Odavić Petrana

2017-07-01

Full Text Available Owing to the fact that the EU is committed to reducing greenhouse gas emissions by 20% below 1990 levels by 2020, and having in mind their high dependence on import of oil and oil derivatives, which, in turn, causes instability of power supply, increasing attention is being paid to renewable energy sources. Given the ongoing pre-accession process of the Republic of Serbia in relation to the EU, in order to determine the capacity of the country to increase the share of energy use from renewable sources, in this paper clustering of selected regions in the EU-28 has been carried out, after which a comparative analysis of regions was performed in terms of potential of agricultural biomass, for the purpose of generating energy. The aim of this study is to determine the level of the region of Vojvodina in relation to ten selected EU regions, based on parameters that affect the potential for using renewable energy sources, primarily residues from agriculture. By applying the K-means method, Borda count method and comparative analysis, and based on empirical data, results show that the region of Vojvodina takes a significant fifth place. Its share of agricultural land ranks it as the first, whereas production of cereals and the total number of farms larger than 100 ha rank it as the second. It could be concluded that Vojvodina is an agricultural region with large quantities of plant remains, primarily those left over from harvest, which represents a significant potential for energy generation from agricultural biomass.

Full Text Available Regions are competing between themselves for the highest position in the country. Achieving and maintaining this position is associated with benefits such as attracting investors, the growth of entrepreneurship living in the region or commune, improvement of housing conditions, local enrichment, lower unemployment, lower social spending and the development of the real estate market. The inventors of the region potential are: entrepreneurs, groups connecting various environments (clusters, associations, Special Economic Zones, knowledge, innovation, and the living conditions of citizens. Regions compete with each other by using monuments, attracting investors and investing funds. The main factors of territorial competition are associated with local resources. The most common and most general division of territorial competitiveness factors are classified into internal and external. External factors include national and global environment, social, economic and spacious politics of the state and other organizations. Internal factors are local opportunities and development needs. They are in the local coordinate system and depend on local resources (quantity and quality of education inhabitants of commune or region, natural resources in the region, the policy of the region - pro-health, pro-family and pro-environmental, infrastructure, their accessibility, quality and efficiency of their use. The aim of this article is to discuss about creators of region potential (mainly entrepreneurs, clusters, associations, Special Economic Zones, and the relationships between them.

Winter precipitation and cyclones in the Mediterranean region: future climate scenarios in a regional simulation

P. Lionello

2007-11-01

Full Text Available Future climate projections show higher/lower winter (Dec-Jan-Feb precipitation in the northern/southern Mediterranean region than in present climate conditions. This paper analyzes the results of regional model simulations of the A2 and B2 scenarios, which confirm this opposite precipitation change and link it to the change of cyclone activity. The increase of the winter cyclone activity in future climate scenarios over western Europe is responsible for the larger precipitation at the northern coast of the basin, though the bulk of the change is located outside the Mediterranean region. The reduction of cyclone activity inside the Mediterranean region in future scenarios is responsible for the lower precipitation at the southern and eastern Mediterranean coast.

The Influence of Globalization on Caspian Region

Full Text Available During last several years the Caspian region has to face the integration into global international process. Long and hard process of globalization is connected not only with the dissolution of the USSR and the emergence of new regional players, but also the desire of extra-regional countries to participate, monitor and control all aspects of life in this region, including energy potential, transport, cultural, ecological and strategic issues. The situation is complicated by the uncertainty of the legal status and the conflict of interest of some extra-regional participants. Until recently, Caspian regional countries were not ready to solve old familiar aches without the biggest international players, such as the USA, China, EU etc. However the safety of the region requires decisions for the benefit of the region in the whole and each country separately.

The microdosimetric regularities of nanometre regions

International Nuclear Information System (INIS)

Bartels, E.R.; Harder, D.

1990-01-01

Regions with nanometre dimensions differ greatly from micrometre regions with regard to the contribution of delta rays to the fluctuation of energy deposition, because the fraction of delta rays escaping from their region of origin increases with decreasing size of the region. Under these geometric conditions, the delta ray term of the distribution of energy deposition in a nanometre region traversed by a primary particle is essentially determined by low energy delta rays originating and stopping within the region. This distribution is found to be practically independent of the mass and energy of the primary particle. The remaining primary-particle-dependent variable determining the fluctuation of energy deposition in the nanometre region is linear primary ionisation density or its energy equivalent, restricted LET. Restricted LET should therefore have the properties of a characteristic parameter of radiation quality. This fundamental conclusion is proven by evaluating the predictive potential of restricted LET for energy deposition fluctuation of electrons, protons and alpha particles in nanometre targets, and with regard to the yield coefficient α for radiation-induced chromosome aberrations in human cells. Methods for the determination of restricted LET are discussed briefly. (author)

Subotica municipality as a learning region

2007-01-01

Full Text Available Some differences in territorial organization between Serbian and EU countries are obvious. The level of centralization and tradition in systems for implementation of ideas are differently back- grounded. However, these are the most important facts for the opportunity to realize Learning Region as a concept of the European future. There is no part of space that should be considered as unchangeable and the way to a better position and Learning Region concept implementation of each region in Serbia in practice should lead towards few necessary steps and further. The starting point is awareness of the facts on the creation of Subotica region as it is at present. The healthy future of each region is provided by looking back in the past and learning from the history. The other important thing is bench marking- learning on the positive and successful experiences of other regions, and finally, making its own concept of Learning Region adapted to local surrounding and true need of local people. Some experiences, suggestions and comparisons will be made in this case study, in relation to one of the Serbian municipalities nearest t to EU neighboring countries in a territorial way. .

ENTREPRENEURIAL ECO-SYSTEMS & REGIONAL ALLIANCES

Full Text Available The study of universities and their role in enterprise development, support and education is very mature. However when Isenberg coined the term ‘entrepreneurial ecosystem’ and suggested that higher education was one of the key foundation blocks of a regional eco-system it threw open the concept of the university having a wider role in the overall business, economic and civic life of a region. What is this wider role, and how do the universities themselves view their place in this evolving entrepreneurial eco-system? How do they fit into Regional Alliances set up to build regional economic development? This paper introduces two pilot Alliances that have been recently formed using both the education institutes and the wider eco-system to drive Innovation and Graduate Employability (The SHIP and REAL Alliances.

Regional Resource Planning Study

International Nuclear Information System (INIS)

2001-01-01

Natural gas and electricity commodities are among the most volatile commodities in the world. Spurred on by the recent significant increases in the price of natural gas, the BC Utilities Commission initiated an investigation into factors impacting on natural gas prices, and the validity of the Sumas index (a market trading point, or interchange where multiple pipelines interconnect, allowing the purchase and sale of gas among market participants) as a price setting mechanism. The Commission also sought the opinions and perspectives of the the province's natural gas industry regarding the high volatility of the Sumas gas prices, and as to what could be done to alleviate the wild fluctuations. Following review of the responses from stakeholders, the Commission issued a directive to BC Gas to undertake discussions on regional resource planning with full representation from all stakeholders. This study is the result of the Commission's directive, and is intended to address the issues contained in the directives. Accordingly, the study examined gas demand in the region, demand growth, including power generation, natural gas resource balance in the region, the California impacts on demand and on supply to the region, supply shortfalls on a peak day, and on a seasonal and annual basis, near term remedies, possible resource additions in the longer term, the economic justification for adding major resources and proposed actions to develop needed resource additions. The study confirmed the existence of a growing capacity deficit, which limits the supply of natural gas to the region. Near term options to alleviate the regional capacity deficit were found to be limited to discouraging power generation from serving export markets, demand side management efforts, and expansion of the WEI's systems by 105 mmcf/d. Longer term solutions would involve larger scale expansion of WEI's T-South capacity, the BC Gas' Inland Pacific Connector Project and the Washington Lateral proposed by

2005-09-01

Soil and plant samples (root and shoot) of Prosopis juliflora were collected in the vicinity of metal based foundry units in Coimbatore and assessed for their heavy metal content (Cu and Cd) to ascertain the use of P. juliflora as a green solution to decontaminate soils contaminated with Cu and Cd. The results showed that Cu and Cd content was much higher in plant components compared to their extractable level in the soil. Furthermore, there exist a strong correlation between the distance of the sources of industrial units and accumulation of heavy metals in plants. Accumulation of Cd in roots is comparatively higher than that of shoots. However, in case of Cu no such clear trend is seen. Considering the accumulation efficiency and tolerance of P. juliflora to Cd and Cu, this plant can be explored further for the decontamination of metal polluted soils. On the other hand, in view of heavy metal accumulate the practice of providing foliage and pods as fodder for live stock should be avoided.

Studies on the mobility of the heavy metals, chromium, lead, zinc and transuranic radionuclides plutonium and americium in three major Indian soils, namely a vertisol-pellustert (black soil), an oxisol (laterite soil) and an entisol-haplaquent (alluvial soil), indicated that more than 98% of the surface-deposited pollutants were retained in the top 0 to 2.5 cm layer when leached with rain-water. In general, the mobility of these elements was either unaffected or marginally reduced at high doses of added organic matter as compared with controls. However, leaching with dilute solutions of (10 -4 M-bar) EDTA, EDDHA and DTPA resulted in enhancement of the mobility of all these pollutants with a high degree of chelate specificity for individual ions, depending upon the soil type. Rapid formation of stable soluble Cr-EDDHA, Pu-DTPA and Am-DTPA complexes facilitated the leaching of these pollutants from the contaminated soils. (author)

Effect of moisture, organic matter, microbial population and fortification level on dissipation of pyraclostrobin in soils.

Reddy, S Navakishore; Gupta, Suman; Gajbhiye, Vijay T

2013-09-01

The dissipation of pyraclostrobin, a strobilurin fungicide, in soil was found to be influenced by soil moisture, organic matter content and microbial population. Among the different moisture regimes, dissipation was faster under submerged condition (T1/2 10 days) followed by field capacity (T1/2 28.7 days) and in dry soil (T1/2 41.8 days). Use of sludge at 5 % level to Inceptisol favoured a faster dissipation of pyraclostrobin, whereas a slower rate of dissipation was observed in partial organic matter removed soil as compared to normal soil. Slower rate of dissipation was also observed in sterile soil (T1/2 47 days) compared to normal soil. Pyraclostrobin dissipated faster in Vertisol (T1/2 21.8 days) than in Inceptisol (T1/2 28.7 days). No significant difference in the dissipation rate was observed at 1 and 10 μg g(-1) fortification levels.

Quantitative signal targeting with alternating radiofrequency labeling of arterial regions (QUASAR) is a recent spin labeling technique that could improve the reliability of brain perfusion measurements. Although it is considered reliable for measuring gray matter as a whole, it has never been evaluated regionally. Here we assessed this regional reliability. Using a 3-Tesla Philips Achieva whole-body system, we scanned four times 10 healthy volunteers, in two sessions 2 weeks apart, to obtain QUASAR images. We computed perfusion images and ran a voxel-based analysis within all brain structures. We also calculated mean regional cerebral blood flow (rCBF) within regions of interest configured for each arterial territory distribution. The mean CBF over whole gray matter was 37.74 with intraclass correlation coefficient (ICC) of .70. In white matter, it was 13.94 with an ICC of .30. Voxel-wise ICC and coefficient-of-variation maps showed relatively lower reliability in watershed areas and white matter especially in deeper white matter. The absolute mean rCBF values were consistent with the ones reported from PET, as was the relatively low variability in different feeding arteries. Thus, QUASAR reliability for regional perfusion is high within gray matter, but uncertain within white matter. © 2014 The Authors.

Migration and regional inequality

DEFF Research Database (Denmark)

Peng, Lianqing; Swider, Sarah

2017-01-01

Scholars studying economic inequality in China have maintained that regional inequality and economic divergence across provinces have steadily increased over the past 30 years. New studies have shown that this trend is a statistical aberration; calculations show that instead of quickly and sharply...... rising, regional inequality has actually decreased, and most recently, remained stable. Our study suggests that China’s unique migratory regime is crucial to understanding these findings. We conduct a counterfactual simulation to demonstrate how migration and remittances have mitigated income inequality...... across provinces in order to show that without these processes, we would have seen more of a rise in interprovincial income inequality. We conclude by arguing that inequality in China is still increasing, but it is changing and becoming less place-based. As regional inequality decreases, there are signs...

From cities and towns to urban networks in Germany – intra regional competition versus regional co-operation and inter regional competitiveness

Directory of Open Access Journals (Sweden)

Bernhard Mueller

2000-01-01

Full Text Available For many decades of the 20th century particular cities and towns were understood as integral parts of national and international urban systems. For many years the theory on central places and hierarchy of central places, first developed by Christaller and amended by Loesch, had a decisive influence on spatial research and regional development policies with guiding principles for urbanisation and the development of settlement patterns. However it is becoming ever more evident, that the planned effects of concepts for harmonising intra- and inter-regional differences were not reached. Moreover, inter-regional competition between neighbouring municipalities, as well as modern life styles and residential choices have caused the emergence of new settlement structures with dispersed spatial patterns and string functional ties. It is also true, that urban networking isn’t an easy task and that it inherently carries numerous obstacles.

Full Text Available Topicality. The Black Sea region is situated in a very important geopolitical manner. Consequently, a large-scale regional collaboration becomes possible within the Black Sea zone and countries get appropriate conditions to launch their activity in this context. Aim: The body of the article is going to analyze the BSEC as one of the most successful regional organizations in the Black Sea area. The paper aims to provide an overview of the regional players’ activity in the framework of the BSEC which are involved in sustaining and strengthening of this organization and also in continuing the reform process in it, developing in the same time relations of cooperation with the EU and other regional initiatives. Methods. This article embraces a row of different scientific methods of data analysis, predictive analytics, historical and statistical overview, descriptive method, case study etc. Results. The countries from the Black Sea basin are the most vulnerable to potential risks and shocks due to the instability of the region. This requires the interstate cooperation in the Black Sea area with no tradition in this field several decades ago. In the same time, countries like Turkey, Romania or Russia aspire to play the role of the regional leader, which can cause regional rivalries. With the help of the regional cooperation and the BSEC in particular, regional countries could learn how to work together for the common benefit. The creation of stable markets, interconnected and transparent regional organizations and initiatives would largely contribute to the security and stability of the Black Sea region.

Modeling the Impacts of Global Climate and Regional Land Use Change on Regional Climate, Air Quality and Public Health in the New York Metropolitan Region

Rosenthal, J. E.; Knowlton, K. M.; Kinney, P. L.

2002-12-01

There is an imminent need to downscale the global climate models used by international consortiums like the IPCC (Intergovernmental Panel on Climate Change) to predict the future regional impacts of climate change. To meet this need, a "place-based" climate model that makes specific regional projections about future environmental conditions local inhabitants could face is being created by the Mailman School of Public Health at Columbia University, in collaboration with other researchers and universities, for New York City and the 31 surrounding counties. This presentation describes the design and initial results of this modeling study, aimed at simulating the effects of global climate change and regional land use change on climate and air quality over the northeastern United States in order to project the associated public health impacts in the region. Heat waves and elevated concentrations of ozone and fine particles are significant current public health stressors in the New York metropolitan area. The New York Climate and Health Project is linking human dimension and natural sciences models to assess the potential for future public health impacts from heat stress and air quality, and yield improved tools for assessing climate change impacts. The model will be applied to the NY metropolitan east coast region. The following questions will be addressed: 1. What changes in the frequency and severity of extreme heat events are likely to occur over the next 80 years due to a range of possible scenarios of land use and land cover (LU/LC) and climate change in the region? 2. How might the frequency and severity of episodic concentrations of ozone (O3) and airborne particulate matter smaller than 2.5 æm in diameter (PM2.5) change over the next 80 years due to a range of possible scenarios of land use and climate change in the metropolitan region? 3. What is the range of possible human health impacts of these changes in the region? 4. How might projected future human

In the procedure a relational dimension is mainly subsumed in the system oriented perspective adopted in selecting the indicators which would best represent the system determinants depending on the goals of the analysis (step a.  In order to get deeper insights into the smartness profile of the European regions, this study makes an effort to account of the relational dimension also in steps b and c of the procedure. The novelties of the proposed approach are twofold. First, by computing region-to-region distances associated with the selected indicators it extends the conventional ranking procedure (step c. Second, it uses a relational database (step b, dealing with the regional participation to the FP7-ICT project, to modify the distances and investigate its impact on the interpretation of the regional positioning.  The main results of this exercise seem to suggest that regional collaborations would have a positive role in regional convergence process. By providing an opportunity to get contacts with the areas endowed with a comparatively more robust smartness profile, regions may have a chance to enhance their own smartness profile.
