This paper assesses the drivers of greenhouse gas emissions and economic performances for a sample dairy farms Protected Designation Origin in France. Investigating caeteris paribus performance, we conclude that synergies are rare. Investing farming equipment, optimizing fuel use or suppressing manure composting can however improve environmental performance by 5 to 13% without impairing profits...

the philosophical-theosophical theory of “the first designation” is macro-theory about instant of “phenomenon existence” and the formation of emanation of multiplicities from the unique. this subject is one of fundamental and hardest problems in “islamic mysticism”. since ibn-arabi is the father of theoretical mysticism in islamic world and so his view about one-ness existence is the foundation...

Photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (FeS, FeS/FeS2, NiO and TiO2). The reaction was carried out in continues flow of CO2 gas bubbled into the reactor. Semiconductor photocatalysts were characterized by X-Ray diffraction (XRD) and Diffuse Reflectance Spectroscopic (DRS) methods. Sulfide ion was used as hole scavenger. T...
