in this paper, the development of a new potassium carbonateon alumina support sorbent prepared byimpregnating k2co3 with an industrial grade of al2o3 support was investigated. the co2 capturecapacity was measured using real flue gas with 8% co2 and 12% h2o in a fixed-bed reactor at atemperature of 65 °c using breakthrough curves. the developed sorbent showed an adsorptioncapacity of 66.2 mgco2/...

reducing co2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. while a variety of technologies and methods have been developed, the separation of co2 from gas streams is still a critical issue. apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

transgenic (tg) mice are very important models of disease, and have been introduced to biological studies since 1982. they are used for understanding the pathobiology of different diseases, finding targets for pharmacological manipulations, and for the evaluation of efficacy and toxicity of medicines in preclinical studies. many different types of tg mice are available as models for human disea...

ABSTRACT: This study aimed to establish the prevalence of animals persistently infected (PI) with bovine viral diarrhea virus (BVDV) in dairy farms at Parana State, Brazil. Samples were collected from 6,465 female Holstein Friesian Dairy Cattle, including less than two years old, females over old who had not given birth farm, and mothers calves diagnosed as infected. The cattle came 40 herds di...

Animals are widespread in nature and the analysis of their shape and motion is important in many fields and industries. Modeling 3D animal shape, however, is difficult because the 3D scanning methods used to capture human shape are not applicable to wild animals or natural settings. Consequently, we propose a method to capture the detailed 3D shape of animals from images alone. The articulated ...

Previous studies from our laboratory have shown that insect hunting is associated with a distinct Fos up-regulation in the ventrolateral caudoputamen at intermediate rostro-caudal levels. It is largely known that ventrolateral striatum participates in the control of orofacial movements and forepaw usage accompanying feeding behavior, but there has been no study investigating its possible roles ...

I review the use of auxiliary variables in capturerecapture models for estimation of demographic parameters (e.g. capture probability, population size, survival probability, and recruitment, emig ration and immigration numbers). I focus on what has been done in current research and what still needs to be done. Typically in the literature, covariate modelling has made capture and survival probab...

Acquisition of food in many animal species depends on the pursuit and capture of moving prey. Among modern humans, the pursuit and interception of moving targets plays a central role in a variety of sports, such as tennis, football, Frisbee, and baseball. Studies of target pursuit in animals, ranging from dragonflies to fish and dogs to humans, have suggested that they all use a constant bearin...

Induced abortion may be desired during a normal or abnormal pregnancy. The methods of induced abortion differ between species mainly because of different sources for progesterone production during pregnancy between species and within a species according to different stages of gestation. In cows and buffaloes, pregnancy can be effectively terminated from 5 to 150 days by administration of luteol...
