Agricultural accumulation has been one of the main source determined the social differentiation in Vietnamese countryside. The complexities of agrarian changes under the post - socialist industrialization with high rate of agricultural land conversion in recent context reveal the new forms of capital accumulation and social differentiation. This research investigates how land conversion process to industrial zones and clusters affected to the way that different groups of peasant households accumulate their resources. The study was carried out in 3 districts of Hung Yen province from 2006 to 2010. The study results are as follows: first, the land conversion to industrialization has impact on not only the decline of household landholdings but also the changes value of land which are the sources of social conflicts and informal land transfer. Second, in the context of land conversion to industrialization with tiny plots of land, low return from agricultural production and more opportunities of non-farm activities, even when non-farm employment is very profitable, peasant households are not likely to give up their land but maintaining agricultural production for not only their basic and secure livelihood but also for their identity. Third, among the affected peasant groups, the households with non-farm background tend to be in better position in engaging to high - earning activities. They are likely the rich peasants in opposed to the poor group with farming background and lost more than 50% of their agricultural land. This research has showed that the industrialization policies have to deal with the proportion of agricultural land would be transferred for industrialization zones and other measures in order to limit the conflicts as well as the social differentiation in countryside.

The present study investigates the combined effect of phosphorous limitation, elevated partial pressure of CO2 (pCO2) and temperature on a calcifying strain of Emiliania huxleyi (PML B92/11) by means of a fully controlled continuous culture facility. Two levels of phosphorous limitation were consecutively applied by renewal of culture media (N:P = 26) at dilution rates (D) of 0.3 d− 1 and 0.1 d− 1. CO2 and temperature conditions were 300, 550 and 900 μatm pCO2 at 14 °C and 900 μatm pCO2 at 18 °C. In general, the steady state cell density and particulate organic carbon (POC) production increased with pCO2, yielding significantly higher concentrations in cultures grown at 900 μatm pCO2 compared to 300 and 550 μatm pCO2. At 900 μatm pCO2, elevation of temperature as expected for a greenhouse ocean, further increased cell densities and POC concentrations. In contrast to POC concentration, C-quotas (pmol C cell− 1) were similar at D = 0.3 d− 1 in all cultures. At D = 0.1 d− 1, a reduction of C-quotas by up to 15% was observed in the 900 μatm pCO2 at 18 °C culture. As a result of growth rate reduction, POC:PON:POP ratios deviated strongly from the Redfield ratio, primarily due to an increase in POC. Ratios of particulate inorganic and organic carbon (PIC:POC) ranged from 0.14 to 0.18 at D = 0.3 d− 1, and from 0.11 to 0.17 at D = 0.1 d− 1, with variations primarily induced by the changes in POC. At D = 0.1 d− 1, cell volume was reduced by up to 22% in cultures grown at 900 μatm pCO2. Our results indicate that changes in pCO2, temperature and phosphorus supply affect cell density, POC concentration and size of E. huxleyi (PML B92/11) to varying degrees, and will likely impact bloom development as well as biogeochemical cycling in a greenhouse ocean.

Distal lower leg soft tissue defect is frequently a challenge to repair, particularly on the tibial crest. The coverage of this kind of lesion has some limitations because of regional minimal blood supply and paucity of local soft-tissue flaps. The perforator pedicled propeller (PPP) method tries to find a new place in lower leg reconstruction in bringing similar tissues at the recipient site and avoiding long and difficult free flap transfer or muscular sacrifice. The authors report on the use of PPP method for a tibial crest exposure after trauma and for a soft tissue defect with osteomyelitis on the tibial crest. [less ▲]

The consumption of wildlife meat is an important source of animal protein for rural and urban population in Congo. A survey on bushmeat trade was undertaken in 21 municipal markets during four weeks, in Brazzaville. The objective of this study was to define the traders’ profile and to evaluate the quantities of games and meat merchandised on the municipal markets. The study methodology combined two approaches: a quantitative one using a questionnaire as principal tool for collecting data, and a qualitative one associating informal survey methods via individual or group interviews. The results showed that women were the most involved in this trade (52%). Markets trader’s monthly income was estimated at 210,428 (US$420) ± 49,128 (US$98,256) FCFA. On average, the bushmeat traders’ were 39 ± 10 years old and 69% of them attended the two levels of secondary education. During four weeks, 3,711 animal carcasses were recorded on the 21 surveyed markets, representing almost 35,790 kg of biomass. Overall, 35 animal species were identified, including 9 the hunting of which was prohibited. The mammals constituted 93.8% of total number of hunted animals, with three dominant orders as the artiodactyls (49.2%), the rodents (22.6%) and the primates (17.7%), of which the Cephalophus, the Potamochoerus, the Atherurus and the Cercopithecus were the most represented. It was also noticed that trapping, an activity which leads to great losses, becomes very important, followed by be helpful alternatives to meet Congolese demand for bushmeat. For a sustainable management of the Congo’s faunic resources, this study suggests the introduction gun-hunting. The Congo-Ocean Railway and the National Road n°2 were used regularly in the transportation of game, to a 72% level. The district of Niari, Lekoumou, Sangha and Pool were the main sources of supply. At the present time, the meat quantities offered in Brazzaville markets don’t seem to be reduced because hunting areas extend always further, often to the detriment of protected areas. Despite the fact that such business squarely growths and shows evidence of overexploitation, activities promoting game farming and breeding of domestic species, in Brazzaville suburbs, are needed to mitigate the impact of bushmeat trade.

The impact of pollution on the environment is causing several problems that are to be reduced as much as possible. One important example is the production of CO2 that is emitted by many transport and industrial applications. An interesting solution is to view CO2 as a source instead of a product that can be stocked. The case considered in this work is the CO2 reformation of methane producing hydrogen and CO. It is an endothermic reaction, for which the activition barrier needs to be overcome. The method of Dielectric Barrier Discharge can do this efficiently. The process relies on the collision of electrons, which are accelerated under an electrical field that is created in the discharge area. This leads to the formation of reactive species, which facilitate the abovementioned reaction. The determination of the electron density is performed by PLASIMO. The study is subsequently continued using the Reaction Engineering module in COMSOL (with an incorporated kinetic mechanism) in order to model the discharge phase. Then COMSOL (continuity and Navier-Stokes equations) is used to model the flow in the post-discharge phase. The results showed that both a 2D and 3D model can be used to model the chemical-plasma process. These methods need strongly reduced kinetic mechanism, which in some cases can cause loss of precision. It is also observed that the present experimental set-up that is modeled needs to be improved. A suggestion is made. [less ▲]

The eradication of poverty and hunger is the first of the Millennium Development Goals (MDGs) established by the United ations. One of the Rwanda’s commitments is the fulfillment of this goal as indicated in its own long term Vision 2020 aimed at enabling Rwandans to emerge from under-development and poverty status by achieving economic growth objectives in combination with social indicators objectives. As it has been researched that the major cause of poverty in developing countries is the high rate of their population growth, this paper is aimed at assessing the fertility preferences and the level of family planning in Rwanda as a tool to poverty eradication. The paper also presents some challenges and some other pathways to improve the socioeconomic welfare of Rwandan population. In this paper descriptive methods have been used to present and analyze data and a Pearson Chi square test has been used to study the association between variables. The results shows that the knowledge of contraception is universal (99%) but the use of contraception methods for family planning is still very low (37%). On the average fertility preferences are 3.2 children which are good if realized. The general conclusion that emerges from the study is that in order to reduce poverty, family planning is a must but lot more are to be done. Among other things, a focus on increasing rural income and agriculture output. [less ▲]

OBJECTIVE: We investigated the association between the proportion of long-chain n-3 polyunsaturated fatty acids (PUFA) in plasma phospholipids from blood samples drawn at enrollment and subsequent change in body weight. Sex, age, and BMI were considered as potential effect modifiers. METHOD: A total of 1,998 women and men participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) were followed for a median of 4.9 years. The associations between the proportion of plasma phospholipid long-chain n-3 PUFA and change in weight were investigated using mixed-effect linear regression. RESULTS: The proportion of long-chain n-3 PUFA was not associated with change in weight. Among all participants, the 1-year weight change was -0.7 g per 1% point higher long-chain n-3 PUFA level (95% confidence interval: -20.7 to 19.3). The results when stratified by sex, age, or BMI groups were not systematically different. CONCLUSION: The results of this study suggest that the proportion of long-chain n-3 PUFA in plasma phospholipids is not associated with subsequent change in body weight within the range of exposure in the general population.

We present a real-time polarization measurement method with a space-variant phase retarder in liquid crystal polymers. This retarder presents a continuous and periodical variation of its optical axis orientation. The method computes the Stokes parameters of an incident beam by studying the intensity distribution after the retarder and a linear polarizer. This paper contains the mathematical modelization, the numerical simulation, the description of the experimental setup, the results for several completely polarized beams and the future developments of this method.

Over the past few years, there has been growing concern about soils and their properties, thanks to greater environmental awareness. Consequently, existing documents on soil are valuable in risk assessment and for the research of well-adapted solutions. In this context, this paper reviews the main stages of soil mapping in Belgium and presents current works to valorize the Digital Soil Map of Wallonia and update associated databases. Belgium is among the first countries to be completely covered by a detailed soil map (1:20,000). The origin of the Soil Map of Belgium, its realisation between 1947 and 1991, the principles and characteristics as well as the related products are described. But since its publication, due to the increasing need of soil information and thanks to the development of geographical information systems the Walloon part of the map was digitalised between 2000 and 2003 by the Digital Soil Map of Wallonia (DSMW) Project. From this early action at regional level, a selection of immediately derived products is presented and briefly commented. However, if these products go beyond the initial objective of agricultural production increase, they do not always meet the environmental challenges nor the future legislation at European, national and regional levels. To fill this gap, the recent tasks carried out by the DMSW team are presented through a description of their methodological and technical framework. The long-term objective is to build Regional Soil Information Systems based on the use of the Digital Soil Map of Wallonia as a tool of integration, structuring and referencing of pedological information.
