The effect of the recently developed graphene nanoflakes (GNFs) on the polymerase chain reaction (PCR) has been investigated in this paper. The rationale behind the use of GNFs is their unique physical and thermal properties. Experiments show that GNFs can enhance the thermal conductivity of base fluids and results also revealed that GNFs are a pot

Objective: To investigate antibacterial potential of Trifolium alexandrinum Linn. (Fabaceae, Egyptian clover) against seven G+ve and eleven G– ve hospitals isolated human pathogenic bacterial strains responsible for many tropical diseases. Methods: Non-polar and polar extracts of the leaves of T. alexandrinum i.e., hexane, dichloromethane (DCM),

In order to model a Wheeled Mobile Robot(WMR) system to improve its maneuverability in a real environment, wheel dynamics, which may violate no-slipping and pure rolling constraints, needs to be studied. In this paper,wheel dynamics with slip is modeled and introduced into the robot overall dynamics. Wheel slip phenomenon is captured and at the sam

Increased disposal costs in many parts of the world due to increasing population have increased interest in utilization of agro industrial residues for value added products. Due to abundant availability, agro industrial residue can be harnessed biotechnologically as an ideal substrate for microbial processes for the production of value-added produc

Monolithic fabrication and advancements in MEMS and nanotechnology have made biomedical implants more popular for monitoring and other applications in humans and animals. One of the primary challenges faced in employing implants is providing a stable battery-less power supply. Inductive coupling is a commonly used means of transferring energy to im

In this investigation, the powder metallurgy (PM) electrode developed from cobalt (Co)and chromium (Cr) powders was used in electrical discharge machining (EDM). This new Co-Cr sintered electrode was used to machine mild steel workpiece with kerosene dielectric fluid. The main objective is to modify its surface characteristics and secure increased

Islam is not a religion in the modern sense of the word; it is rather complete and comprehensive way of life, guiding mankind in every walk of life including business. The Qur'an and Hadith have both highlighted significance of and rules for business. They view business as the best way to ensure safety and further growth of wealth and property.

The inevitable implications of fragmenting farmland ownership are (i) uneconomic land sizes and farm operations, (ii) greater tendency to convert the farmland to other uses (and hence, the subsequent decline of food production capabilities of the country as a whole) and (iii) under-investment in the land as co-owners disagree on how land should be

The demand of intelligent machines that may recognize the spoken speech and respond in a natural voice has been driving speech research. The challenging in speech recognition systems due to the language nature where there are no clear boundaries between words, the phonetic beginning and ending are influenced by neighbouring words, in addition to th

There are quite a number of researches in proposing digital image watermarking using Discrete Wavelet Transform (DWT). However, it is clearly observed that each of them is individually distinctive in terms of its scopes and applications. In this paper, a proposed system was thoroughly explained. It includes general work flow, proposed algorithms fo
