The purpose of this study was the improvement of cold flow and lubricity characteristics of biodiesel produced from the palm-sesame oil blend. Extreme learning machine (ELM) and response surface methodology (RSM) techniques were used to model the production process and the input variables (time, catalyst amount, methanol to oil ratio, and duty cycl

The Islamic legal maxim (al-qāʿidah al-fiqhiyyah) “no harm shall be inflicted or reciprocated” has become particularly significant in this era of pandemic. In the current context, this legal maxim is reasonably expected, provided that if they are adequately employed, to influence people’s choices and guide them to make certain decisions whi

Introduction: Hearing acuity, central auditory processing and cognition contribute to the speech recognition difficulty experienced by older adults. Therefore, quantifying the contribution of these factors on speech recognition problem is important in order to formulate a holistic and effective rehabilitation. Objective: To examine the relative con

Introduction: Immunosuppressed individuals and paediatric population are susceptible to infections. This case report depicts the presentation and severity of COVID-19 infection in a single case report of a Leukemic child on chemotherapy and compares the course of disease with previously reported case reports of immunocompromised children with COVID

Abstract: This research work focuses on investigating the lubricity and analyzing the engine characteristics of diesel–biodiesel blends with fuel additives (titanium dioxide (TiO2) and dimethyl carbonate (DMC)) and their effect on the tribological properties of a mineral lubricant. A blend of palm–sesame oil was used to produce biodiesel using

Sustainable micro-alloyed materials play a major role in advanced technology for the development of optimum material integrity properties in various structures. During the past decades, efforts have focused on high strength low alloy steels (HSLA) to expand its application to various fields such as shipbuilding, oil and gas pipelines, building cons

In this paper, the λ-model with nearest neighbor interactions is considered with competing Potts interactions on the Cayley tree of order-two. Notice that if λ-function is taken as a Potts interaction function, then this model reduces to the Potts model with competing interactions. The Potts model with considered interactions has only been numeri

Individual mental health has become a primary global concern. In Pakistan, the prevalence of mental health issues is still unclear, as not many studies have assessed the level of mental health literacy (MHL) in the country. This systematic review aims to bridge this gap by encouraging the early detection of mental disorders, lessening stigma, and i

The demand for renewable energy is steadily increasing due to rapid population growth and economic development worldwide. An additional reason is that fossil fuel reserves are limited, and this situation results in their non-uniform availability globally. Furthermore, the attitudes of the society, energy policies and technology choices are constant

Petroleum, petrochemical or oil and gas industry is one of the important industrial sectors in Malaysia. The safety in the workplace is one of the vital issues that need to be taken seriously. Every worker should know about the occupational safety and health organization to protect them from any accidents and injuries. The purpose of this study was
