In this paper, a wideband circularly-polarized spiral antenna is proposed to be used for CubeSat application. The antenna covers two of CubeSat frequencies; the S-band (2.2 GHz) and X-band (8 GHz). The proposed antenna belongs to the wideband and frequency-independent antenna category, which are known to provide a constant radiation pattern, impeda

الأمثال من الفنون الأدبية التي تمثل الوقائع والأحداث الحقيقية، ودراسة أصول الأمثال العربية من حيث مناسباتها وحكاياها متوفرة شائعة؛ بخلاف نظيرتها الملايوية التي لا تُعلم أصولها، ولكن؛ يمكن ا

Carotenoids can be obtained naturally from several sources like fruits, algae, plants, and crustaceans, contributing to varying red or yellow pigmentation. Carotenoids are acyclic substances having several transformations, leading to more than 800 compounds derived by the addition of oxygen-abundant functional groups or end group cyclisation. Hence

Solitary waves or solitons is a nonlinear phenomenon which has been studied intensively due to its application in solid-state matter such as Bose-Einstein condensates state,plasma physics, optical fibers and nematic liquid crystal. In particular, the study of nonlinear phenomena occurs in the structure of waves gained interest of scholars since the

Calcium-looping technology is defined as one of the most desirable methods of carbon capture, utilization and storage (CCUS). However, because of sintering, rapid deactivation of CaO�sorbents is currently a major barrier to this technology. The stability of calcium based sorbent may be enhance by incorporating them with inert support materials su

Researchers are currently interested in studying the dynamics of the wave field in a nonlinear and dispersive medium. The Nonlinear Schrödinger Equation (NLSE), which is the fundamental equation that explains the phenomenon, has paved the way for research in a variety of fields, including soliton scattering. However, if the fields have a large num

The era of globalization has caused widespread movement of people and has resulted in migration of labour. Coupled with the digitalization of information, this has sparked an increasing trend of international marriages, i.e. marriages between two persons of different nationalities. The trend has generated new challenges including the determination
