Methods are described for the production of the monamycins by Streptomyces jamaicensis in shake flasks and jar fermentors. The effects on the fermentation of variations in pH, temperature, medium composition, volume of inoculum, and strain of the organism are discussed. The methods employed for the extraction and for the microbiological assay of the antibiotics are outlined.

Cloud computing enables us to use services over Internet whenever we require. A major feature of the cloud services is that user’s data are usually processed by unknown machines to the users, so users afraid of having no control on their own data. This is a barrier to the adoption of cloud services. To address this problem, in this paper, we propose a decentralized information accountability fr...

Preeclampsia is a potentially life threatening disorder of pregnancy which presents with raised blood pressure and proteinuria after twentieth week of gestation. It is one of the leading and mystical causes of maternal and fetal mortality worldwide. Abnormal placentation is suggested to be possibly the key feature of this disorder. Preeclampsia has been attributed to the presence of a circulati...

Electric fish monitor modulations in sensory feedback from their own electric organ discharges (EODs) to locate moving objects and to detect interfering EODs of their neighbors. The gymnotoid genus Eigenmannia minimizes detrimental effects of jamming by EODs of its neighbors by shifting its own EOD frequency away from a neighbor's EOD frequency that is too close to its own. Since the animal low...

As beginning neuroscience students, we are taught that behaviour is controlled via output to various types of effectors, with different types of muscles and glands being the prime examples. Later, when we discover the world of weakly electric fish, we learn that the electric organ also qualifies as an effector and that the electric organ discharge (EOD) is a form of motor output. Typically, one...

The alpha and beta subunits of human chorionic gonadotropin are secreted both as a combined, noncovalently linked dimer form as well as uncombined, free forms by human trophoblastic cells. We have utilized the cultured choriocarcinoma cell line JAR to determine what regulates the combination of the two subunits. The human chorionic gonadotropin subunits produced by JAR cells were biosynthetical...

This article presents an optimization of the drinking water treatment process at SUCRIVOIRE station. The objective is to optimize coagulation and flocculation (fundamental said plant)by determining optimal dosages products injected then proposes a program for calculating dose coagulant in order automatically determine latter according raw quality. contribution has advantage saving user from any...

Abstract Green extraction processes to obtain high value bioactive compounds from raw natural materials and wastes has gained attention the past few years. In present study, we investigated a Natural Deep Eutectic Solvent derived two products, namely choline chloride glucose as potential solvent for of tannin spent coffee ground(SCG). A was used coagulant with Poly aluminium chloride(PAC) flocc...

The goal of this study was to investigate the performance coagulation-flocculation, and sedimentation tests reduce contaminant concentrations in domestic wastewater ecologically acceptable levels. were performed at (ONEE) laboratory using a jar test apparatus (GPB FLCDidatec, France) for enhancing primary treatment effluent from plant Ain Aouda City, Rabat, Morocco. Aluminum sulphate Al 2 (SO 4...

We investigated the expression of interleukin-1 (IL-1) receptors and their involvement in the regulation of the serotonin transporter gene expression in human placenta. IL-1beta is an activator of the serotonin transporter gene expression in JAR human placental choriocarcinoma cells as demonstrated by an increase in the steady-state levels of the transporter mRNA and in serotonin transport acti...
