Effect of organic soil amendments on increasing soil N retention and reducing N losses from agricultural soils
Li, Zhijie (2023-09-01)In the course of my doctoral studies, I actively engaged in my advisor's research projects, which involved participating in the establishment of lysimeter experiments and conducting research on isotopes. My research findings ... -
The effect of phosphorus amendments on nitrogen fixation and growth of trees on salt-affected croplands in the lower reaches of Amu Darya, Uzbekistan
Djumaeva, Dilfuza (2011-12-07)Afforestation, particularly with the use of N2-fixing trees (NFTs), is an option for ecological restoration of salinized, irrigated croplands in the lower reaches of the Amu Darya River. But current knowledge of enhanced ... -
Effect of sub-clinical endometritis on miRNAs expression profile of endometrial and oviductal epithelium and its implication of early embryonic development
Ibrahim, Sally Rashad Elsaid (2015-03-17)Understanding the molecular mechanisms associated with regulation of inflammatory responses during female genital tract infection is one step forward for development of diagnostic and therapeutic strategies in bovine ... -
The effect of sulfur deficiency in pea (Pisum sativum) on factors related to nitrogen fixation and on sulfate transporters
Pourmoayyed, Parisa (2016-11-29)Sulfur has a vital role in the plant life cycle. S deficiency reduces optimal yield and quality in legumes which lead to a reduction in nutritional value of food and feed. S deficiency also alters the symbiotic interaction ... -
Effect of thyme, oregano and their major active components on performance and intestinal microbial populations of broilers
Abdel-Wareth, Ahmed Aboubaker Abdel-Moniem (2011-05-20)The aim of the present study implied an evaluation of the potential of different increasing levels of thymol, carvacrol, a mixture of thymol and carvacrol, as well as thyme and oregano as feed additives in broiler diets, ... -
The effectiveness and efficiency of forest conservation policies to reduce deforestation in the Peruvian Amazon
Giudice Granados, Renzo (2023-01-23)Between 2015 and 2020, 9.3 million hectares of tropical forests were annually deforested. Deforestation represents the second largest source of carbon emissions globally, reduces biodiversity and ecosystem services, and ... -
Effectiveness and Perspectives of Access and Benefit-sharing Regimes in the Convention on Biological Diversity: A Comparative Analysis of Costa Rica, the Philippines, Ethiopia and the European Union
Richerzhagen, Carmen (2007)The decline of biodiversity has reached an alarming rate and all the approaches that have been undertaken in the past were not sufficient to stop the on-going process. One of these approaches is <em>Access and Benefit-Sharing</em> ... -
Effectiveness of soil and water conservation measures for land restoration in the Wello area, northern Ethiopian highlands
Shiene, Shimeles Damene (2012-11-12)Soil-erosion-induced land degradation is a great challenge in the Ethiopian highlands. Consequently, the government has invested in soil and water conservation (SWC) measures, mainly farmland terracing and exclosure of ... -
Effects of 137Cs and 90Sr on structure and functional aspects of the microflora in agricultural used soils
Niedrée, Bastian (2013-03-01)At long sight <sup>137</sup>Cs and <sup>90</sup>Sr are the main radionuclides responsible for the contamination of agricultural soils due to core melts in nuclear power plants such as Chernobyl or Fukushima. Once deposited ... -
