Climate change studies forWest Africa tend to predict a reduced potential for farming that will affect the food security situation of an already impoverished population. However, these studies largely ignore farmers’ adaptations and market adjustments that mitigate predicted negative effects. The paper attempts to fill some of this gap through a spatially explicit evaluation of the impact of cl...
Many strategies have been used to increase the number of bacterial cells that can be grown from environmental samples but cultivation efficiency remains a challenge for microbial ecologists. The difficulty of cultivating a fraction of bacteria in environmental samples can be classified into two non-exclusive categories. Bacterial taxa with no cultivated representatives for which appropriate lab...
The development of science and technology has made people's quality life better better, the mature use electricity lives more convenient faster. However, this also led to a drastic increase in non-renewable energy such as coal oil. In 2021, about 4,108 billion kilowatt-hours (kWh) (or 4.11 trillion kWh) were generated at utility-scale generation facilities United States, 546 million short tons ...
A survey was carried out in France in 1999 in a Densely Populated Pig Area (DPPA) and a Sparsely Populated Pig Area (SPPA) from which 80 and 55 pig farms were respectively investigated. The two areas were compared regarding the number of respiratory disease outbreaks in fattening pigs on each farm per year with a multiple correspondence analysis and hierarchical clustering. The two areas exhibi...
A new species, Amblydromalus amazonicus n. sp. is described and illustrated based on adults of both sexes. Individuals were found in association with plants natural vegetation (Amazon Forest), uncultivated guarana crops, exotic fruit (residential area), states Amazonas Mato Grosso, Brazil. The type material A. akiri Nuvoloni, Lofego, Rezende Feres was re-examined the number setae as well chaeto...
Soil erosion is one of the effective elements on soil destruction. Many empirical and theoretical models has been developed for soil erosion estimation 137 Cs technique is used as new and accurate method in this case across world. For applying this technique on computing erosion and sediment rate, an appropriate conversion model should be selected. For this propose in this study proportional, m...
ABSTRACT-The influence of intensive crop rotation on the distribution of potassium forms and clay mineralogy was assessed under a Mediterranean condition in the Piranshar region, northwest of Iran. For this purpose, surface soil samples in relation to six soil sub-groups from crop rotationfiled (sugar beet, wheat, pea, and barley) over five decades and the adjacent uncultivated lands were descr...
