Microalgal growth curve, after the exponential phase, shows a stationary phase where algalbiomass production is inhibited and remains constant by some factors such as nutrientdepletion and intrinsic behavior. The present study is concerned with evaluating effects ofthe culture medium condition and intrinsic behavior on biomass production by Dunaliellatertiolecta. To this end, effect of pH, nutr...

v. dannon showed that spherical curves in e4 can be given by frenet-like equations, and he thengave an integral characterization for spherical curves in e4 . in this paper, lorentzian spherical timelike andspacelike curves in the space time 41 r are shown to be given by frenet-like equations of timelike andspacelike curves in the euclidean space e3 and the minkowski 3-space 31 r . thus, finding...

I N T R O D U C T I O N The palatal chemoreceptors of the carp display a rather peculiar type of response to varying concentrations of electrolytes (Konishi and Niwa, 1964). Dilute solutions of salts, especially those with polyvalent anions such as Na3citrate and Na 2 HP04 , produced strong responses. However, an increase in concentration depressed receptor activity, although the activity incre...

Calcineurin inhibitors (CNIs) are maintenance immunosuppressive drugs that have been used as the main therapy for organ transplantation for many years. Of the CNIs, cyclosporine (CYA) and tacrolimus (TAC) are used in clinical practice. The CYA binding protein is cyclophilin and that of TAC is FK-binding protein (FKBP), but both drugs have same mechanism of action: the inhibition of interleukin ...

Abstract. Sequential reactions consist of linked reactions in which the product of the first reaction becomes the substrate of a second reaction. Sequential reactions occur in industrially important processes, such as the chlorination of methane. A generalized series of three sequential reactions was analyzed in order to determine the times at which each chemical species reaches its maximum. To...

BACKGROUND China is now under a period of social transition, and inequity is evident in the field of health care. We aimed to investigate regional health-care inequalities in children's survival in Zhejiang Province, China. METHODS In our study, monitoring data of Zhejiang Province from 2005 to 2014 was collected. The flow of data collection of community-district-city for urban areas or villa...

The results of toxicity tests can be used to calculate the potentially affected fraction (PAF) of species in an ecosystem at a given pollutant concentration using statistical extrapolation methods. The PAF curve indicates the fraction of species from the original community that may become inhibited at each elevated pollutant concentration and is a measure of the ecotoxicological risk. Pollution...
