For fifth generation (5G) lower band wireless application at a frequency of (4.5–5.5) GHz, recently ASEAN region countries have suggested 5G forums and band rejection antennas for 5G (4.5–5.5) GHz lower band. A UWB antenna has been constructed and suggested by use of the Roger RT5880 with defected ground on a rectangular radiating patch and a r

In ASEAN countries, the fifth generation (5G) forum proposed a 5G application lower frequency band (4.5–5.5) GHz and the fixed satellite service (FSS) C-band at (3.3–4.2) GHz. Previous research works have demonstrated that the complexity of antenna design, large size and in most of the cases, active elements that were added to antenna has made

This paper aims to synthesize high purity nano-sized silica from rice husk ash (RHA) by chemical method and investigate its physical and chemical properties. Through a controlled burning of rice husk, the white-colored RHA is obtained. Next, the RHA is subjected to the pre-treatment of acid leaching and thermal treatment. The synthesizing process h

Introduction: The aim of this study was to assess and evaluate nurses' knowledge, perception, and expectation regarding the potential roles of pharmacists in pharmaceutical care at private outpatient haemodialysis centres. Methods: A descriptive, cross-sectional study was conducted among nurses who were working in private outpatient haemodialys

The heat transfer performance of the material is mainly affected by the surface-to-volume ratio and specific surface area. This paper presents an evaluation of hard-hydrophobic nano-CuO coating on the heat transfer performance of copper material. The nano-CuO coating was de-veloped using the electrochemical oxidation method in 0.1 M oxalate solutio

The current development of science, technology, and industrial revolutions did not happen suddenly. Many years of empirical investigation efforts by human intelligence have brought the world to its present state. As a result, new technologies and innovations would move human civilization to a more advantageous position every day. One of the other r

With today’s advanced technology microstrip patch antennas are more flexible and stronger than ever before. These antennas can work on various frequencies ranging from low to high for a huge variety of applications including medical, military and quite a few more. This paper presents the textile antennas those are designed for Wi-MAX application

Wearable antennas have grown in popularity in recent years as a result of their appealing features and prospects to actualize lightweight, compact, low-cost and adaptable wireless communications and surroundings. These antennas have to be conformal and made of lightweight materials in a low-profile arrangement when attached to various parts of the

Edisi Kedua Buku Dosa-dosa Akhir Zaman mengupas hakikat manusia sebagai khalifah Allah di muka bumi ini yang lahir bersama fitrah keimanan namun diuji dengan nafsu syahwat yang menyesatkan. Dengan penbambahan bab baru mengenai Dosa-dosa Jahiliah, perjalanan hidup manusia dalam melaksanakan amanah ini akan sentiasa berhadapan dengan badai cobaan yan

Background: Understanding the mechanism of antimicrobial action is critical for improving antibiotic therapy. For the first time, we integrated correlative metabolomics and transcriptomics of Pseudomonas aeruginosa to elucidate the mechanism of synergistic killing of polymyxin–rifampicin combination. Methods: Liquid chromatography-mass spectromet
