Rigidoporus microporus is an economically important plant pathogenic fungus causing particularly severe losses to the rubber industry worldwide. The pathogen is responsible for white root rot (WRR) disease, infecting the host roots via white fibrous mycelia, causing vascular disfunction, and visible symptoms including leaf discolouration and dieback in severely infected trees. The final stage of the disease is characterized by the appearance of basidiocarps at the tree collar. The development of WRR in rubber plantations is dependent on fungal diversity in the soil, pH, temperature, and cation levels. Several -omics approaches have been undertaken to understand how R.microporus functions with the objective, ultimately, to control WRR. Unfortunately, no resistant rubber clone has been identified to date. The disease is managed through physical and chemical methods that are laborious and negatively impact the environment, respectively. Recent developments in research on R.microporus shed.....

A phytochemical study has been carried out on CH 2Cl 2extract of Alphonsea cylindrica leaves, resulting in the isolation of three new morphinan alkaloids. They are kinomenine (1), N -methylkinomenine (2), and hydroxymethylkinomenine (3). The structures of these compounds were elucidated by extensive spectroscopic analysis (1D and 2D NMR, IR, UV, HRESIMS) and comparison with the data reported in literature for similar alkaloids. Kinomenine (1) and N -methylkinomenine (2) showed weak inhibition against S. aureus (MIC values of 1 and 2 = 500 ?g/mL; pIC 50values in 95% C.?I. of: 1 = 2.9 to 3.0; 2 = 2.9 to 3.1), while kinomenine (1) also showed weak inhibition against E. coli (MIC values of 1 = 500 ?g/mL; pIC 50value in 95% C.?I. of: 1 = 2.9) by broth microdilution method. The results obtained can be used as future referencefor the discovery of morphinans and the potential of A. cylindrica as an antibacterial source. 2023 Georg Thieme Verlag. All rights reserved...

The prevalence of non-communicable diseases has increased worldwide, and their complications pose a significant threat to Malaysia, creating the leading causes of morbidity. Due to that, many instruments were developed to assess a healthy lifestyle in general; however, the measurement issue remains important for scholars, especially when it involves different samples. Furthermore, the quality of instruments is influenced by their validity and reliability. This study aims to translate, adapt, and establish validity evidence and reliability for the Malay version of the Adolescents Healthy Lifestyle Questionnaire in Klang Valley, Malaysia. The validity evidence was tested using exploratory factor analysis (EFA) and reliability using Cronbachs alpha. There are 11 components: healthy diet, physical activity, substance abuse, health responsibility, sleep quality, interpersonal relationships, social health, mental health, accident prevention, environmental health, and suicidal tendencies, wit.....

Teaching alternating currents, ac or sound waves, is incomplete without an introduction to the oscilloscope. An oscilloscope is a tool that graphically displays electrical signals and shows their time dependence. However, due to the pandemic, triggered by the SARS-CoV-2 virus, many students do not have the opportunity to master the use of an oscilloscope. Face-to-face teaching activity has been interrupted in both schools and higher institutions. The sudden change to online teaching created problems among educators, especially for laboratory activities. The central issue is creating laboratory activities without going into the labs for the students to acquire the required skills, especially the basics of how to operate an oscilloscope. In order to create an opportunity and engaging environment, we suggested the use of the web-based and stand-alone oscilloscope. The software consists of a low-frequency (signal) generator (LFG), a direct current power supply, and an oscilloscope. The LFG.....

In this study, we design and construct a low-cost experimental kit for the force on a straight current-carrying conductor in a magnetic field experiment, namely EM-FOR. The kit consists of several pairs of rectangular-shaped permanent magnets with different polarities facing each other on a U-shaped aluminium casing as the source of the magnetic field, a straight copper wire at the centre between the two magnets as the electrical conductor, conductor rings and connecting wires to connect conductor and electrical source, and an electronic balance to measure the magnitude and to determine the direction of the force on a straight current-carrying conductor in a magnetic field. The design of the EM-FOR experimental kit was validated by determining the magnitude and direction of the force on a straight current-carrying conductor in a magnetic field for normal and reverse connections to a power supply. The constructed kit can be utilized for three experiments: the effects of applied current,.....

Municipal solid waste(MSW) management has been a growing problem in fast-developing cities. A considerable amount of solid waste is generated daily and disposed anywhere, which creates an unhealthy environment. This study aims to develop a model to determine household solid waste (HSW) generation using multiple linear regression and identify suitable landfill sites to ensure proper MSW disposal in Rangpur City, Bangladesh. Socioeconomic variables data like average monthly income, educational level, family size, age of family head, and average HSW generation per day were collected from 381 respondents through stratified random sampling with a 95% confidence level. Multi-criteria decision analysis (MCDA) was performed using variables like surface water, slope, road network, and land use through GIS and remote sensing to find suitable landfill sites. Results of the model show no multicollinearity as the variance inflation factor was estimated to be less than 2 for each independent variabl.....

Manipulating surface plasmon resonance (SPR) of silver (Ag) and gold (Au) nanoparticles (NPs) in amorphous material may open new possibilities in optic and photonic fields. Driven by this fact, heat treatments (HT) were used to tune the excitation mode of SPR. The Nd3+ doped magnesium-zinc-sulfophosphate glasses embedded with Ag and Au NPs were heat-treated at 450 C for 6 and 12 h and characterized using X-ray diffractometer (XRD), high-resolution transmission electron microscope (HRTEM), UVVisNIR absorption and photoluminescence (PL) spectrometer. The mean size of NPs was slightly reduced (4.68 nm? 4.35 nm) after 12 h of HT due to the elastic ripening process, causes by internal pressure within NPs. Unusual multiple SPR bands were evidence around 419, 481, 613, 676, 776, 848 and 939 nm after the glass (AgAu6h) is heat-treated for 6 h. Thirteen absorption bands are recorded within 326875 nm, corresponding to the Nd3+ ion transitions. The NIR PL bands of Nd3+ ion were detected around 87.....
