Political cyber-troopers is a term that refers to activists paid to spread political propaganda in the media. The emergence of the cyber-troopers movement was seen to be significant in the 12th General Election and became more active in the 14th Election. In line with this development, the issue of political cyber-troopers began to gain the attention of scholars who studied its existence and role in the political context in Malaysia. However, studies on defining the term politics cyber-troopers are still limited. Thus, this term is equated with netizens and keyboard warriors. The lack of a suitable definition to describe cyber-troopers in Malaysia causes a negative stigma in the community. Therefore, this study analyses the definition and typology of political cyber-troopers in Malaysia using the conceptual framework of political astroturfing. This study uses qualitative methods through interview instruments with ten informants consisting of academics, cyber-troopers and political acti.....

Background: Studies assessing post-activation potentiation (PAP) responses comparing male and female athletes are conflicting. Objectives: This study investigated whether differences exist in the duration for optimal post-preload stimulus measures on performance in male and female team sport athletes. Methods: Twenty-four participants (12 males and 12 females) participated in the study. Two familiarization sessions were conducted with each participant. Then, three experimental conditions were implemented, incorporating a standardized warm-up, followed by back squats (conditioning exercises) and varying passive recovery times of 4 min (PAP4), 8 min (PAP8), or 12 min (PAP12). Following the recovery, players performed three physical performance measures related to team sports: A countermovement jump, a modified agility t-test, and a 20-m linear sprint. The significance level was set at P < 0.05. Results: All performance measures were significantly greater in PAP12 than in PAP4 and PAP8 co.....

The chemical composition of the essential oil of Rothmannia schoemannii Tirveng. (Rubiaceae) was investigated for the first time. The essential oil was obtained by hydrodistillation and fully characterised by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). In total, 28 components were identified in the essential oil, which made up 99.6% of the total oil. The essential oil is composed mainly of ?-eudesmol (30.8%), ?-cadinol (18.2%), caryophyllene oxide (6.5%), ?-cadinene (5.5%), and ?-eudesmol (5.4%). The essential oil exhibited cytotoxic activity against J5 (human hepatocellular carcinoma) and A549 (human lung adenocarcinoma) cells with IC50 values of 112.5 and 98.5 ug/mL, respectively. 2023, INNOVHUB - Stazioni Sperimentali per l'Industria S.r.l - Area Oli e Grassi.

The aim of this research is to formulate activated carbon monolith from hazardous waste of cigarette filter butts (CFB) for electrode material monolith design in solid-state supercapacitor application. Potassium hydroxide (KOH) was selected for activation. The ratio of CFB to KOH varied in terms of weight between 1:2 and 1:4, thereby obtaining activated cigarette filter carbon (ACFC). The carbon that has been obtained is designed to be solidly in the form of an additive-free monolith. Monolith-activated carbon is physically characterized to examine thermal decomposition profiles (pre-carbonized), structure, composition, morphology, surface area adsorption, and electrochemical measurements. The optimum precursor was marked with high wettability with self-O-doped of 5.44%.in carbon content of 94.56%. Activated carbon electrodes prepared from ACFCs showed an optimum specific capacitance of ~87.17 F g-1, which is a more ecologically responsible method of producing supercapacitors. 2023 The.....

Most integrals in Localised Boundary Domain Integral Equations (LBDIEs) comprise singularities. This paper aims to produce numerical solutions of the LBDIEs for the Partial Differential Equations with variable coefficients. The singularities of the boundary integrals in LBDIEs will be handled by using a semi-analytic for logarithmic singularity and a semi-quadratic analytic method for r?2 singularity. Whereas the singular domain integrals are handled by using the Duffy transformation. The LBDIEs that we consider are associated with the Neumann problem, which can be solved with a condition. If it can be solved, the solution is, however, unique up to an additive constant. We add a perturbation operator to the LBDIEs to convert the LBDIE to a uniquely solvable equation. The perturbed integral operator leads the perturbed LBDIEs to a dense matrix system that disable the use of methods in solving sparse matrix system. We solve the system of linear equations by Lower-Upper (LU) decomposition.....
