CO2 capturing has become very significant option to reduce the emission of CO2 in the atmosphere and hence, minimizing environmental issues. Among solid CO2 sorbent, calcium oxide (CaO) is an attractive regenerable sorbent for CO2 capturing because of their reactivity and high CO2 absorption capacity. CaO alone suffers from rapid decay of CO2 adsor

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

Sialorrhea also known as drooling is defined as excessive saliva in the mouth or hypersalivation. The symptom causes discomfort for most stroke patients or other neurological disorders such as Parkinson's disease. Sialorrhea may affect physical, mental, self-esteem and social life because the patient needs to accommodate the excessive salivatio

A new method of ductile mode machining of silicon using high speed end milling with diamond coated tool and assisted by compresses air blowing has been developed. This method is capable of removing the ductile and gummy chips before they get deposited on the machined surface since gummy chips can not be removed by mechanical means once they are dep

With the advent of several advanced difficult-to-cut materials, and with the availability of heat resistant tool materials has posed a great challenge in industries. Hardened steel is one of these difficult-to-cut materials. During the last few decades numerous studies have been conducted to improve the machinability of these materials and many lar

Nickel-based, creep-resistant, superalloy Inconel 718 is amongst the most difficult alloys to machine. The main reason for the poor machinability of the alloy is the high work-hardening rate by the precipitation of a γ’ phase and the presence of hard abrasive phases such as titanium carbide, niobium carbide and the Ni3AlTi phase. Generally, incr

Chatter is an abnormal tool behaviour which it is one of the most critical problems in machining process and must be avoided to improve the dimensional accuracy and surface quality of the product [1]. The most critical limitation in machining productivity and part quality is the occurrence of the instability phenomenon called regenerative chatter [

Introduction: As COVID-19 Pandemic hit across the globe, the closure of higher institutions and the shifting to online platform has become the stress factors related to learning activities for the nursing students. Hence, this study was conducted among Malaysian undergraduate nursing students to determine the level of perceived stress and to examin

This Antioxidant activity and phenolic compound was found in Justicia gendarussa (JG) via total phenolic content (TPC) and α,α-diphenyl-β-pycrilhydrazil hydrate (DPPH) radical scavenging assays. The assays were applied on aqueous and methanolic extracts of leaves, callus culture and cell suspension culture of JG. Callus was induced from green an
