The significance of high gain directional antennas stems from the need to cope up with the everyday progressing wireless communication systems. Due to low gain of the widely used microstrip antenna, combining multiple antennas in proper geometry increases the gain with good directive property. Over other array forms, this paper uses concentric circ

Cancer is a serious global health problem, which resulted in 8.2 million deaths in 2012 alone. Amongst different types of cancer, lung cancer is the most lethal and contributes 19.4% of cancer deaths. Better disease-free cancer survival rates have been reported when surgery is followed by systemic chemotherapy. Efficient treatment can be achieved t

One of the most challenging works on compact antenna design is to maintain the flexibility orientation. This paper demonstrates a coplanar waveguide (CPW) fed monopole antenna with rubber substrate at 2.45 GHz center frequency for ISM band application. The proposed antenna attained the realized gain at 4.06 dB with the radiation efficiency around 9

At childbirth (parturition), zinc (Zn) homeostasis in cord blood (CB) can be affected by a number of factors: Zn in maternal blood, parturition related stress as well as metallothionein (MT). Both Zn and stress are known inducers of MT which is primarily involved in Zn homeostasis. This study analyzed Zn concentration [Zn], in CB components and MT-

In this paper, a characterization and comparison between the effects of Electron irradiation on low noise amplifiers (LNAs) implemented in a Silicon-Germanium (SiGe) Heterojunction Bipolar Transistor (HBT) and Gallium-Arsenide (GaAs) HBT technologies, respectively, was carried out. Previous studies [1] have shown that the properties of SiGe and GaA

Extraction of gelatin using traditional acid-base pretreatment method has several limitations such as time consuming and causes serious water pollution. Chemical treatment often being used as an alternative process to overcome the weaknesses of the conventional method. However, excessive chemical elements would damage the structure of the gelatin d

Cancer still presents enormous challenges in the medical world. Currently, the search for anticancer compounds has garnered a lot of interest, especially in finding them from the natural sources. In this study, by using Sulforhodamine B (SRB) colorimetric assay, compounds, extracted from supermeal worm (Zophobas morio) larvae using two types of aci

Antifungal peptides have been successfully extracted from whole body larvae of Zophobas morio (Fabricius) by using acidified isopropanol. To ensure that the extraction is cost effective for maximum yield, Response Surface Methodology (RSM) using a Central Composite Design (CCD) strategy was adopted to optimize the extraction process parameters. The

Battery cell balancing in every electrical component such as home electronic equipment and electric vehicle is very important to extend battery run time which is simplified known as battery life. The underlying solution to equalize the balance of cell voltage and SOC between the cells when they are in complete charge. In order to control and extend
