Inequality in Vietnamese Urban-Rural Living Standards, 1993-2006 Using data from five waves of the Vietnam Household Living Standard Survey, we find evidence of significant urban-rural expenditure inequality. Urban-rural inequality in Vietnam increased dramatically from 1993 to 1998, and peaked in 2002 before reducing slightly in 2004, and significantly in 2006. The urban-rural gap also monoton...
Since its implementation in 1990 the human development index (HDI), the flagship indicator of multidimensional development, has attracted a great deal of attention and critics in academic, political and media circles. It initiated a new stage in the discussion of appropriate indicators to measure socioeconomic development. Until now, the vast majority of empirical work using the HDI-concept tak...
Avian pathogenic E. coli and human extraintestinal pathogenic E. coli serotypes O1, O2 and O18 strains isolated from different hosts are generally located in phylogroup B2 and ST complex 95, and they share similar genetic characteristics and pathogenicity, with no or minimal host specificity. They are popular objects for the study of ExPEC genetic characteristics and pathogenesis in recent year...
Background: Spatially correlated overabundances of N15 and O18 observed in some low-density graphite meteoritic grains have been connected to nucleosynthesis taking place the helium-burning shell during core-collapse supernovae. Two reactions which identified as important final abundances are F18(n,?)N15 F18(n,p)O18. The relative strengths F18(n,p)O18 depend sensitively on ?0 p0 decay branches ...
Closely related Escherichia coli B2 strains O1:K1, O2:K1, O18:K1, and O45:K1 constitute a major subgroup causing extraintestinal infections. A DNA pathoarray analysis was used to develop a PCR specific for this subgroup that was included in the multiplex phylogenetic-grouping PCR method. Our PCR may serve to identify this virulent subgroup among different ecological niches.
Escherichia coli is a highly versatile species, causing diverse intestinal and extraintestinal infections. Here, we present the complete genome sequence of PMV-1, an O18:K1 extraintestinal pathogenic E. coli (ExPEC) strain that is used as a model for peritonitis in mice and was useful for deciphering the innate immune response triggered by ExPEC infections.
به منظور ارزیابی هیدرولوژی ایزوتوپی منابع ذخیرهسازی آب و گروهبندی آنها براساس پارامترهای فیزیوگرافی و شیمیایی مؤثر در حوزهی آبریز، آزمایشهایی در طی سالهای 1388 تا 1390 در 30 تالاب مختلف در شمال ایران انجام شد. نمونهها در طی فصلهای بهار، تابستان، پاییز و زمستان جمعآوری شده و مورد تجزیه و تحلیل شیمیایی و ایزوتوپی قرار گرفتند. دادههای ایزوتوپی نشاندهندهی این بودند که تالابها طیف وسیعی...
از موضوعات مهم در مباحث اقتصاد شهری بحث تأثیر صرفه های تجمیع فعالیت های اقتصادی در یک منطقه است. اقتصاددانان تجمیع را از مهم ترین علت های رشد و توسعه ی مناطق می دانند. تجمیع به دو دسته ی تجمیع تخصصی شده و تجمیع متنوع شده تقسیم می شود. هر یک از این اشکال، منافعی را برای بنگاه های تجمیع شده ایجاد می کنند که سبب رشد کل منطقه می شود. در این مطالعه به بررسی اثرات تنوع و تخصص اقتصادی بر رشد اشتغال در...
distribution and diversity of income in rural regions according to the characteristics of households and in the framework of sustainable livelihood must be investigated. in this study, in order to investigate the status of income distribution and diversity and its impact on the economy of rural households in alamout region multinomial logit model has been used. the required dates are related to...
