in this paper, we prove some approximate fixed point results for proximinal valued $beta$-contractive multifunctions on metric spaces. we show that our results generalize some old fixed point results in the literature.

Conventional steam activation pyrolysis of waste materials such as oil palm kernel shell for production of biochar was investigated using central composite design. Conventional steam activation was carried out via an initial carbonization of oil palm kernel shell to obtain biochar and thereafter steam activation of the biochar using the conventional heating to produce activated carbon. Addition...

The Mexico-U.S. wage gap alone cannot explain the large increases in migration from Mexico to the U.S. in the last three decades. This paper explores three alternative migration determinants: family migrant networks, the Mexican migrant-smuggling (coyote) industry and the rural economy. The premise of this paper is that successive cohorts of migrants and an expanding coyote industry have led to...

Mukteswar strain of Newcastle disease (ND) virus was propagated in 9-day-old embryonated eggs via allantoic route. The harvested allantoic fluid with haemagglutination (HA) titre of 1024 (EID50 10) was inactivated using 0.1 percent formalin solution. Two experimental vaccines were prepared in light mineral oil with aqueous to oil ratio of 1:2 ( MK-VAC-I) and 1:4(MK-VAC-II).The hydrophile lipoph...

The present research has been undertaken with the aim to develop a transdermal gel formulation of naproxen, which would attenuate the gastrointestinal related toxicities associated with oral administration. The potential gastrointestinal disorders associated with oral administration of naproxen (NSAID’s) can be avoided by delivering the drug to the inflammation site. Gel based formulations are ...

This study was initiated in view of the phenomenon that hydrostatic turntable rails are prone to scrape damage when liquid is running under fixed partial load. The existing bias-load oil film bearing characteristics mainly calculated by using calculus integration method and CFD fluid simulation method. calculating formula obtained complex inefficient. calculation requires 3D modeling meshing fi...

We describe a method for creating discrete femtolitre-scale water-in-oil droplets on demand, based solely on a geometrically induced reduction in oil/water interfacial area at microfabricated junction orifices. This on-demand generation method is driven by self-shear of droplets due to interfacial tension induced forces resulting from a localized transition in microchannel height. The magnitude...

The present study was carried out to determine the fatty acid composition of the black cumin (Nigella sativa L.) samples obtained from total ten different regions of Turkey, Iran and Syria and the comparison of variations in species. The fatty acid compositions of black cumin samples were determined by gas chromatography (GC). The main fatty acids of the fixed oil were linoleic acid, oleic acid...

The research objective was to produce activated carbon from palm-oil shells by one step pyrolysis and steam activation in a fixed bed reactor with the diameter of 100 mm. The studied variables were activation temperature, activation time, palm-oil shell sizes and flow rate of air. The results showed that the optimum condition was 1.18-2.36 mm of palm-oil shells at 750C for 2 hr with air flow ra...
