Background: Fibroblast cell lines have different application in biological research including nuclear transfer in cloning, feeder layer of embryonic stem cells, wound healing research and tissue engineering. The objective of the present study was to determine the proper pregnancy age for collecting and culturing guinea pig fetal fibroblast. Materials and Methods: Guinea pig fetuses were collect...

Solving the problem of locating services in a given context requires a methematical abstraction so that its complexity can be managed by means of an iterative search through context simulations. Keeping the interface between planners and the model within planners’ knowledge domain is achieved by an interactive tool that encourages exploration and comparison among different possible solutions. A...

We determine the characteristics of the 7mm to 20 cm wavelength radio variability in Sgr A* on time scales from days to three decades. The amplitude of the intensity modulation is between 30 and 39% at all wavelengths. Analysis of uniformly sampled data with proper accounting of the sampling errors associated with the lightcurves shows that Sgr A* exhibits no 57or 106-day quasi-periodic oscilla...

In a DC microgrid, droop control is the most common and widely used strategy for managing power flow from sources to loads. Conventional has some limitations such as poor voltage regulation improper load sharing between converters during unequal source voltages, different cable resistances, variations. This paper addressed of conventional by proposing simple adaptive technique. The proposed met...

The article explores the use of proper names as a source wordplay in classroom bilingual interaction English second language. It is noted that becomes means accommodation to onomastic system foreign language when trigger metalinguistic reflection. author emphasizes process deliberate deviation from norms which name standard unit (‘normema’) undergoes linguistic reinterpretation and turns into n...

a total of 700 day old female broiler chicks (ross 308) were distributed into seven groupsin acompletely randomized designwith five replicates, and 20 chicks in each replicate. dietary treatments, timeof the switch from an unsaturated sunflower oil (sfo) to a saturated tallow (t)dietary fat source, were: 1) sfo for the entire growth period (6 weeks), 2) sfo for 5 weeks followed byt for last wee...
