Zingiber zerumbet (L.) Roscoe ex Sm. is a herbaceous medicinal plant from the Zingiberaceae family. Previous studies have mainly focused on the essential oils of the plant with little attention to its secondary metabolites. LCMS-Orbitrap is used to analyze ethanolic extract of Z. zerumbet rhizome. Dereplication is a technique applied to identify chemical constituents based on their accurate mass and comparison with custom databases, Dictionary of Natural Products (DNP), and literature using an operating system named MZmine 2.53. In this study, we have identified chemical constituents related to several classes, including flavonoids, terpenoids, diarylheptanoids, terpenes, phenolic compounds, and fatty acids. Our results provide useful information for further isolation and identification of other unknown compounds and mass spectroscopy-based metabolite profiling of Zingiber species...

A drastic increase in healthcare demand has come from the explosive growth of the older population. The elderly are, on average, more vulnerable to health problems than other age groups. Unpredictable events, such as sudden falls, can be avoided with proper monitoring. Activity recognition can help people avoid potentially dangerous behaviours by aiding in the detection of unexpected events. Most of the existing approaches require complex sensors and environment setup, involve data filtering and noise removal steps, and most often the chosen learning models need to be tuned and carefully designed for optimal performance. This study emphasizes light implementation, fast training time, easy experimental setup, and minimal parameter tuning. Human activities are captured using smartphone sensors in this study. Students and senior residents from a local home care facility are among the volunteers for this study. The necessary data sets are obtained from the accelerometer sensor on the smart.....

The conjoint method, which is based on fuzzy sets of numbers, is widely used to describe linguistic values for human preference in an uncertain environment. However, the fuzzy sets used to describe the membership function of linguistic value do not realistically represent the physical world, so the conjoint method can fill the gap and produce more meaningful results. The fuzzy numbers conjoint method is used in this paper to analyze the achievement goals of undergraduates in the learning of calculus. One hundred and seven selected Bachelor of Science (Hons) Mathematics and Bachelor of Science (Hons) Actuarial Science students from one public university in Klang Valley, Selangor, participated in this study. The data for this study, which was distributed via Google form, was based on a previous study's Achievement Goals Questionnaire. The fuzzy number conjoint method with similarity measure based on geometric distance, ambiguity, value, area, left and right height were used to c.....

Iraqi corporations still perform below expectation and are yet to fully comply with corporate social responsibility disclosure (CSRD) requirements. Past research on corporate governance attributes (CGA) had shown positive effects on CSRD. Thus, this research aims to investigate the effects of CGA, such as board of directors (BOD), audit committee (AC), and ownership structure (OWSR) on the level of CSRD in Iraqi non-financial companies by focusing on the moderating effect of earnings management (EM). CSRD in this study refers to disclosure in environment, product and consumers, community, and human resource. Hypotheses are developed using the multi-theoretical framework, including agency, stakeholder, and legitimacy theories. Data were collected from annual reports of 38 non-financial companies listed on the Iraq Stock Exchange (ISX) from 2016–2019.
