a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

BACKGROUND: Fat-tailed sheep breeds have a  unique  ability  to  tolerate  periods  of  negative  energy  balance  due to seasonal changes in feed availability. This ability is attributed to presence  of  fat-tail  as  a  body  energy  reserve, however the exact underlying  mechanisms  controlling  the  response  of adipose  tissue  depots  to variations in energy balance in fat-tailed breeds a...

reproductive efficiency in dairy cattle has been decreased over the last 5 decades despite significant gains in genetic selection, improved reproductive technologies and nutritional care. in high-yielding dairy cattle, the negative energy balance (neb) during the first week post-partum adversely affects ovarian activity, mainly follicle growth and steroidogenesis. circulating levels of non-este...

Reproductive status is tightly coupled to metabolic state in females, and ovarian cycling in mammals is halted when energy output exceeds energy input, a metabolic condition known as negative energy balance. This inhibition of reproductive function during negative energy balance occurs due to suppression of gonadotropin-releasing hormone (GnRH) release in the hypothalamus. The GnRH secretagogue...

BACKGROUND & AIMS Bioactive ingredients have been shown to reduce appetite and energy intake. The magnitude of these effects might depend on energy balance why it was investigated how capsaicin, green tea, CH-19 sweet pepper as well as green tea and capsaicin affect appetite and energy intake during respectively negative and positive energy balance. METHODS 27 subjects were randomized to thre...

this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...

BACKGROUND Addition of capsaicin (CAPS) to the diet has been shown to increase energy expenditure; therefore capsaicin is an interesting target for anti-obesity therapy. AIM We investigated the 24 h effects of CAPS on energy expenditure, substrate oxidation and blood pressure during 25% negative energy balance. METHODS Subjects underwent four 36 h sessions in a respiration chamber for measu...

this study was done to gain insights into transcriptional regulation of negative energy balance (neb) assoctiated genes. overexpressed genes in neb were identified using microarray and rna-seq data and promoter analysis of these overexpressed genes was applied to identify novel transcription factors. moreever, string database was used to construct a regulatory network of identified transcriptio...
