The growth of agricultural total factor productivity (TFP) is seen as a driving force for the sustainable development agriculture. Meanwhile, promotion urbanization in China has exerted profound impact on production. This paper calculates TFP and analyzes effect urbanization. Firstly, DEA-Malmquist method used to calculate dynamic change from 2004 2016. Secondly, spatial spillover investigated ...
The development of the agricultural sector is essential for any economy, including Azerbaijan, largest economy in South Caucasus, as it plays an important role food security, rural development, and environmental protection. For oil-dependent also diversification non-oil sector. this reason, Azerbaijani government has adopted several programs materialized massive investments to promote growth. T...
Investigating Agricultural Productivity Growth and Convergence in Iran and Eastern African Countries
The issue of convergence or divergence of productivity has important policy for regional poverty reduction and increasing standards of living. If productivity converges to a common level without intervention, there is little need for explicit policies in lagging regions to promote catch up. On the other hand, productivity has divergence trend, then explicit policies would be needed to prevent f...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Type IV pili (Tfp), which have been studied extensively in a few Gram-negative species, are the paradigm of a group of widespread and functionally versatile nano-machines. Here, we performed the most detailed molecular characterisation of Tfp in a Gram-positive bacterium. We demonstrate that the naturally competent Streptococcus sanguinis produces retractable Tfp, which like their Gram-negative...
Modern economic geography is a new filed in economic studies highlighted by Krugman’s papers (1991 & 1992) increasingly welcomed by economists. Krugman in his papers, proposed a theoretical model that holds opening trade leads to increased wages in some geographical areas where major productions are industrial. Increased real wages in such areas leads to more labor employment while scale econom...
There have been extensive studies exploring the relationship between agglomeration economies and economic growth. However, far less attention is paid to the nonlinear relationship of urbanization economies–firm productivity nexus, especially in developing countries. This paper aims to explore how urbanization economies impact the total factor productivity (TFP) of research and development (R&D)...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Green transformation of energy use in China’s transport sector will promote sustainable development the country. This paper extends Bounded-adjusted Measure and Luenberger indicators to detect performance inland across 2006–2015. In framework, climate change traffic accident risks are taken as undesirable outputs. addition, source-specific variable-specific decomposition proposed for investigat...
This study investigates the impact of climatic variability on both agricultural production and total factor productivity (TFP) in Southern United States (US). It also aims at identifying drivers this region. The analysis is tailored to inform decision makers about effective policy options increase sustain important We use data from US Department Agriculture, National Climatic Data Center, Geolo...
