Marine natural products have attracted the attention of scientists to isolate novel biologically active metabolites. Several promising metabolites were discovered from marine sponges with different biological activities including antimicrobial and anticancer. By far, more than 36% of the metabolites discovered from marine organisms were isolated fr

ASEAN countries have proposed fifth generation (5G) forums for 5G applications at a frequency of 4.5–5.5 GHz and band stop antenna for 5G lower band from 4.5 GHz to 5.5 GHz. One UWB antenna have been designed and proposed by using RT 5880 with partial grounding on rectangular patch and ring shape resonator (RSR) on the ground. A single band notch

The high gas-sensing performance of semiconductors is mainly due to the high surface-to-volume ratio because it permits a large exposed surface area for gas detection. This paper presents an evaluation study for the efects of nano-CuO coating parameters on the CO gas-sensing performance. The efects on gas-sensing performance and heat transfer efcie

Because of the technology that is demanded today’s the microstrip patch antennas have more strength and flexibility. Different studies of antennas have shown that it can operate on different frequencies, at lowing for a large number of applications such as medical, military and so many applications. So, a textile antenna is presented for the Wi-M

Acacia Seyal gum (ASG), also known as gum Arabic, is an antioxidant-rich soluble fiber. ASG has been reported to have many biological activities, including anticancer, antidiabetic, antiulcer, and immunomodulatory activity. Extraction of bioactive compounds from ASG is commonly performed using conventional extraction methods. However, these techniq

Recently lower frequency band 4.5–5.5 GHz is proposed by the ASEAN countries for 5G cellular application and therefore, it is essential of designing an ultra-wideband (UWB) antenna for the particular band-notched characteristics. In this article, a compact tuning fork shape ultra-wideband (UWB) patch antenna with a variable band-notched character

Date fruit is a type of fruit grown mainly in the eastern region. Favorable research findings on date nutritional value have led to dates becoming one of the well-known fruits consumed by many people in the world. In general, people only consume the date flesh but throw the seed as waste. Recent studies have indicated the existence of nutritional b

Date fruit is a type of fruit grown mainly in the eastern region. Favourable research findings on date nutritional value have led to dates becoming one of the well-known fruits consumed by many people worldwide. In general, people only consume the date flesh but throw the seed as waste. Recent studies have indicated nutritional benefits in date see

Brushless DC (BLDC) motors are very popular for applications in automation and electric vehicle systems due to their unique features. Although these motors have many advantages over conventional DC motors, they also suffer some limitations in their functionality due to their direct dependability on the controller driver circuit. The proportional in
