Optimization of the process parameters for the extraction of a product from a solid substrate after bioconversion is essentially important tomaximize the yield. The extraction of citric acid from the solid substrate of oil palm empty fruit bunches (EFB) after bioconversion was initially optimized by following single factor variation. Following this

The paper explains how the importance of experiential learning and the context of site visit as an informal learning environment correspond towards enhancing the informal education. Sociocultural theory implies that understanding a phenomenon entails understanding its development. Thus, understanding learning means studying in detail how it unfolds

Micro dry wire electrical discharge machining (μDWEDM) is an environmental-friendly machining process where gas is used as the dielectric fluid instead of liquid. In this process, certain modifications of wire electrical discharge machining (WEDM) are required during the machining operation for stable machining. In μDWEDM, the process is consider

Whether in the time of war or peace, media, considered the ‘Fourth Authority’, must struggle to present the truth to the public, making no concession to any kind of authority, whether legislative, executive or judicial. This study, which adopts descriptive-analytical method, gives a brief account of the 2011 Arab popular revolts with reference

Recently there is an increase in interest to use art as a part of the healthcare healing process and environment. The artwork is now regularly set as a condition in design feature for hospitals. The benefits of art in hospitals and medical institutions have been confirmed by numerous studies and subjective evidence. The artwork produced can be a co

In this paper, a helical coil tube in tube heat exchanger was designed and used in carbon dioxide solar assisted heat pump system (SAHP) to provide hot water for domestic applications and to operate an air gap membrane desalination (AGMD) unit. Both theoretical and experimental studies to investigate the performance of the gas cooler with Glycol Et

Boswellia carterii (BC) {Burseraceae family} essential oil (EO) were extracted by hydrodistillation process. Gum Arabic (GA) {Acacia senegal} polymer particles containing a BCEO were prepared by spray drying technique. The mean particle size and its distribution, as well as the zeta-potential of the microcapsules, were analyzed and found Z-Average

How foreigners receive instructions to protect themselves from COVID-19 is the subject of this study. Social campaigns have focused on its own citizens while few or limited attention is given on how foreigners subject themselves to accept the safety instructions given by the government. The world struggles with fighting COVID-19 pandemic and author

Almost 50 species of Ophiorrhiza plants were reviewed in this work and the main objective is to critically analyse their distribution, phytochemical content, biological activity, and propagation. Moreover, the information would be useful in promoting the relevant uses of the plant, especially in the medicinal fields based on in vitro and in vivo st
