Conservation agriculture (CONS A) is a sustainable system based on crop rotation with no tillage. It has various environmental advantages compared to conventional (CONV A): decreased water evaporation, erosion, and CO 2 emissions. In this first study of its kind, we aim evaluate the impact type sheep gastrointestinal parasites. Two lamb groups aged between 5 10 months were randomly included gra...

ocal and regional land-use and land-cover change is an important ingredient in the larger problem of global environmental change. Land-use patterns, driven by a variety of social processes, result in land-cover changes that affect biodiversity, water and radiation budgets, trace-gas emissions, and other factors that, cumulatively, alter the global climate and biosphere. Most research on global ...

The ChEss project of the Census of Marine Life (2002-2010) helped foster internationally-coordinated studies worldwide focusing on exploration for, and characterization of new deep-sea chemosynthetic ecosystem sites. This work has advanced our understanding of the nature and factors controlling the biogeography and biodiversity of these ecosystems in four geographic locations: the Atlantic Equa...

Investigation on climate change is coordinated by the Intergovernmental Panel on Climate Change (IPCC), which has the delicate task of collecting recent knowledge on climate change and the related impacts of the observed changes, and then developing a consensus statement from these findings. The IPCC's last review, published at the end of 2007, summarised major findings on the present climate s...

Ecuador’s Yasunı́ Man and the Biosphere Reserve—located at the intersection of the Amazon, the Andes mountains, and the equator—is home to extraordinary biodiversity and a recently contacted Amazonian indigenous group known as the Waorani (or Huaorani). Relatives of the Waorani, the Tagaeri and Taromenane, still live in voluntary isolation deep in the reserve, with no peaceful contact with the o...

ch4, c2h6 and c2h4 are the most important outlet gaseous of oxidative couple methane (ocm) reaction and this process is a new technology for conversion of natural gas to ethane and ethylene products. in this study, adsorption of ocm outlet hydrocarbons over 10x zeolite has been examined at equilibrium conditions. temperature and pressure are the most effective operational parameters in the batc...

Concentration of atmospheric methane is considered to have a significant effect on climate because of its GWP (Global Warming Potential), which is 21 times of CO2. Methane is generated by the process of methanogenesis under wet anaerobic conditions, oxidation by methanotrophic bacteria and transportation to the atmosphere. Wetlands are the major source of methane emission, because of the presen...
