The design practice of timber structures in Malaysia is still based on permissible stress codes as stated in Malaysian Standard (MS) 544: Part 2 and MS 544: Part 3, which was adopted from the British Standard (BS) 5268. The British Standard was later completely replaced by Eurocode 5 (EC5) in 2009. Therefore, to preserve the continuity of design concepts specified in the British code of practice, local designers should adopt an EC5 limit state design to generate safe and economical designs. However, new strength data based on characteristic values which comply with EC5 for Malaysian tropical hardwoods are still lacking. The aim of this study was to investigate the compressive strength properties of nine structural-sized Malaysian tropical hardwood species namely Balau, Kempas, Kelat, Resak, Kapur, Keruing, Mengkulang, Light Red Meranti and Geronggang tested according to European Standard (EN) 408. A compression test was performed to measure the compressive strength and modulus of elasticity of the timbers and were used to derive characteristic values. The equation for determining characteristic compressive strength given in EN 384 was also assessed to verify that whether it is suitable for high density Malaysian hardwoods, as this equation was derived from softwood and European hardwoods. The results revealed that the derived characteristic values are higher than the values given in EN 338 for the relevant strength classes, particularly for heavy and medium hardwood with densities greater than 700 kg/m3. A verification of the equation used in EN 384 to determine compressive strength characteristic value yields a different equation, fc,0,k=2.2 fm,k0.7. This shows that the EN 384 equation is not suitable to be used with hardwood timber with a density more than 700 kg/m3, since it will underestimate the strength value.

Despite the fact that several cases of unsafe pesticide use among farmers in different parts of Africa have been documented, there is limited evidence regarding which specific interventions are effective in reducing pesticide exposure and associated risks to human health and ecology. The overall goal of the African Pesticide Intervention Project (APsent) study is to better understand ongoing research and public health activities related to interventions in Africa through the implementation of suitable target-specific situations or use contexts. A systematic review of the scientific literature on pesticide intervention studies with a focus on Africa was conducted. This was followed by a qualitative survey among stakeholders involved in pesticide research or management in the African region to learn about barriers to and promoters of successful interventions. The project was concluded with an international workshop in November 2021, where a broad range of topics relevant to occupational and environmental health risks were discussed such as acute poisoning, street pesticides, switching to alternatives, or disposal of empty pesticide containers. Key areas of improvement identified were training on pesticide usage techniques, research on the effectiveness of interventions targeted at exposure reduction and/or behavioral changes, awareness raising, implementation of adequate policies, and enforcement of regulations and processes.

Non-native plants can reduce grassland biodiversity, degrade wildlife habitat, and threaten rural livelihoods. Management can be costly, and the successful eradication of undesirable species does not guarantee the restoration of ecosystem service delivery. An alternative to the eradication of invasive species in rangelands is to target the restoration of diversity and heterogeneous plant structure, which have direct links to ecosystem function. In this study, we evaluate patch-burn grazing (PBG) with one and two fires per year and variably stocked rotational grazing in Poa pratensis- and Bromus inermis-invaded grasslands using traditional (cover) and process-based (diversity and vegetation structural heterogeneity) frameworks in central North Dakota, USA. Within 3–4 years of initiating management, we found little evidence of decreased Poa pratensis and Bromus inermis cover compared to continuous grazing (Poa pratensis F3,12 = 0.662, p = 0.59; Bromus inermis F3,12 = 0.13, p = 0.13). However, beta diversity increased over time in all treatments compared to continuous grazing (tPBG1 = 2.71, tPBG2 = 3.45, tRotational = 3.72), and variably stocked rotational treatments had greater increases in spatial heterogeneity in litter depth and vegetation structure than continuously grazed pastures (tvisual obstruction= 2.42, p = 0.03; tlitter depth = 2.59, p = 0.02) over the same time period. Alternative frameworks that promote grassland diversity and heterogeneity support the restoration of ecological services and processes in invaded grasslands.

Published: July 2022

In this study, molecular dynamics simulation was used to study the effect of SiO2/Al2O3 mass ratio on the structural properties and viscosity of molten fused red mud. The stability of various T–O bonds in the melt was elucidated by analyzing the bond angle and coordination number; the degree of polymerization, and the stability of the melt were explored by analyzing the number of T–O–T bridging oxygen (BO) and the distribution of QSin and QAln of [SiO4]4− as well as that of QSin and QAln of [AlO4]5−; the self-diffusion coefficient of each atom was determined by mean square displacement (MSD) analysis; and the trend of the melt viscosity was analyzed according to the relationship between diffusion and viscosity. The results show that as the ratio of SiO2/Al2O3 increases, the viscosity of molten fused red mud first increases, then decreases, and finally increases. This is because Ti4 and Fe3+ combine with O2− to form [TiO6]8− octahedron and [FeO4]5− tetrahedra, which increase the degree of depolymerization of the melt.
AuAg Nanoparticles Grafted on TiO2@N-Doped Porous Carbon: Improved Depletion of Ciprofloxacin under Visible Light through Plasmonic Photocatalysis
Authors: Jiménez-Salcedo Marta , Monge Miguel , Tena María Teresa 
Published: July 2022

TiO2 nanoparticles (NPs) were modified to obtain photocatalysts with different composition sophistication and displaying improved visible light activity. All of them were evaluated in the photodegradation of ciprofloxacin. The band gap of TiO2 NPs was successfully tailored by the formation of an N-doped porous carbon (NPC)-TiO2 nanohybrid through the pyrolysis of melamine at 600 °C, leading to a slight red-shift of the absorption band edge for nanohybrid NPC-TiO2 1. In addition, the in-situ formation and grafting of plasmonic AuAg NPs at the surface of NPC sheets and in close contact with TiO2 NPs leads to AuAg-NPC-TiO2 nanohybrids 2–3. These nanohybrids showed superior photocatalytic performance for the degradation of ciprofloxacin under visible light irradiation, compared to pristine P25 TiO2 NPs or to AuAg-PVP-TiO2 nanohybrid 4 in which polyvinylpyrrolidone stabilized AuAg NPs were directly grafted to TiO2 NPs. The materials were characterized by transmission electron microscope (TEM), High Angle Annular Dark Field—Scanning Transmission Electron Microscopy—Energy Dispersive X-ray Spectroscopy HAADF-STEM-EDS, X-ray photoelectron spectroscopy and solid UV-vis spectroscopy. Moreover, the active species involved in the photodegradation of ciprofloxacin using AuAg-NCS-TiO2 nanohybrids were evaluated by trapping experiments to propose a mechanism for the degradation.

Groundwater overexploitation is a critical issue in the North China Plain (NCP), resulting in groundwater level decline and surface subsidence for the last half-century. This problem, however, has been greatly alleviated by the South-to-North Water Diversion (SNWD) Project since 2015. Monitoring of this process has been steadily improved in recent years using water level and geodetic observations. Here, we characterize the water storage change at the Huairou groundwater reserve site (HGRS) in Beijing due to the SNWD by combining Interferometric Synthetic Aperture Radar (InSAR) data of the Sentinel-1 satellites, continuous Global Positioning System (GPS) data, and well water level data observed during the same time. InSAR observations revealed subsidence up to ~400 mm in the Beijing plain but uplift at ~40 mm in the HGRS during 2015–2019, and more than 70% of the uplift occurred from October 2018 to January 2019. By integrating the most significant uplift deformation during October 2018 to January 2019 with water level observations at the same time, we estimated the storativity of the confined aquifer system at HGRS as 1.68–7.82×10−3, weighing in the correction for effective stress and surface deformation for various situations. Based on the estimated aquifer storativity and the observed water level change in the unconfined and confined aquifer, the recharged water storage for the confined and unconfined aquifers was estimated as 1.20–1.39×107 m3 and ~2.86×108 m3 from 6 October 2018 to 22 January 2019, respectively, which is about 4% and 91% of the surface water recharge through river channels in the same period due to the SNWD Project. Our study demonstrates that integration of geodetic and hydrological data can provide crucial information for the assessment of groundwater circulation and assistance of groundwater management.

Authors: Grabar Natalia , Kukharenko Angelica 
Published: July 2022

The article considers the transformational changes in the modern library environment, in which digital media content is the main source of information and communication. The tendencies in the studies of the axiological sphere of library science, namely the observance of the humanistic aspect of the activities of libraries as a center of science, education, culture, and communication, are highlighted. A decrease in the general intellectual level of users against the background of informatization of society has been noted, which requires improvement in the nature and types of information, as well as methods for obtaining and using it. The need to organize communication in libraries, to provide people with the opportunity to realize their need for it, was stated. It is noted that the figurative-sensual means of library communication are associated with communication at the interpersonal and intercultural levels. Library targeted activities related to art expand the users area of interest, help them to better understand the phenomena of reality and themselves. The ability to interact in the process of communication, to apply the skills of influencing dialogic action is recognized as a necessary component of the professional activity of librarians. Library dialogue is the universal means of establishing contacts and consolidating people.
The value aspects of figurative-sensual communication in servicing the modern user with libraries are investigated. The role of values in the vital activity of youth and society is substantiated. Currently, there is a transformation of information needs and value orientations in the library sector. It is noted that the formation of a harmoniously developed personality without the intellectual and aesthetic impact of the speech element of speech interaction is impossible. It is provided for deeping attention to the problem of recognizing and highlighting the value dominants of figurative-sensual communication in the modern library space.

Information literacy program that can be categorized as a training program requires evaluation to show whether the program has been achieved as expected. This study aims to develop a literacy program and determine the effectiveness of the information literacy program on Library Visit Day. The study used a descriptive research method with the research population being all participants of the information literacy program on the 2019 Library Visit Day at the Ministry of Agriculture's PUSTAKA totaling 69 people. Samples were taken from 27 participants in the literacy class for researchers and students, and 42 people in the literacy class for extension workers/farmers/general public. The research method refers to the evaluation of the effectiveness of the training program/training Kirkpatrick (2004). The results of the study show that all of the indicators assessed (level 1-level 4) in the evaluation of the information literacy program carried out by PUSTAKA on Library Visit Day 2019 were considered very satisfactory even though they had not been able to meet the 100% expectations. The improvement strategies needed to improve the information literacy program in the future are: socialization through various media is needed with sufficient time; development of training materials; additional time for the implementation of the literacy program; literacy development programs for students; making a guide for program literacy participants; develop literacy programs directly to extension workers and farmers in the field.

Tujuan tulisan ini untuk menganalisis perjalanan hidup Hamka sehingga dapat diidentifikasi latar minat istimewa sejarah Hamka, termasuk pengaruh faktor agama, pendidikan dan sosio-kultural terhadap persepsi dan interpretasi sejarah Hamka. Sedangkan pendekatan yang digunakan adalah pendekatan historiografi. Latar belakang minat istimewa Hamka di bidang sejarah: Pertama, Hamka berasal dari lingkungan keluarga yang islami, sehingga Hamka dididik dengan semangat dan jiwa Islam. Pandangan hidup Hamka yang Islami ini terakumulasi pada dua sasaran, yaitu demi perjuangan Islam dan kewajiban moril terhadap bangsa. Kedua, bahaya yang mengancam Islam justeru dari lapangan kebudayaan, untuk itu Hamka terpanggil berkiprah di lapangan kebudayaan, khususnya tentang sejarah Islam. Ketiga, karena penulisan sejarah Islam di Indonesia di dominasi oleh penulis asing, maka banyak terjadi kekeliruan dan kesalahan data yang tidak sesuai dengan fakta yang ada, hal ini disebabkan kepentingan kolonial dan kepentingan misionaris Kristen. Pandangan Hamka terhadap sejarah dipengaruhi oleh agama Islam, pendidikan, dan sosio-kultural, sehingga bagi Hamka sejarah Islam itu adalah sejarah dan agama Islam. Hamka adalah sejarawan dari masyarakat dan sejarawan otodidak, yang dibentuk oleh lingkungan keluarga, lingkungan alam tempat kelahirannya, kondisi zaman dan masyarakat tempat ia tumbuh dan hidup di tanah kelahirannya, Minangkabau, serta di perantauan yang berpindah-pindah
A method to induce stress in human subjects in online research environments

Published: July 2022

AbstractThis paper presents a method to induce stress in human subjects during online participation in research studies without the presence of researchers. In this study, participants in the stress-inducing condition (N = 52, 44%) were asked to answer general knowledge and mathematical questions which people often get wrong, and did so under time pressure as well as receiving feedback. In contrast, participants in the control condition (N = 66, 56%) did not have time pressure or receive feedback. The stress manipulation was found to be effective, as the reported state anxiety and visual analog scale on stress scores were higher for the stress group than for the non-stress group (both findings, p < 0.001). Consistent findings were found when accounting for trait anxiety as a moderator, with the exception of the state anxiety levels in high trait anxiety group. This stressing method combines the established stress conditions of uncontrollability (such as time pressures) and social evaluative threats (such as negative feedback). In addition, the method contains specific measures (such as a commitment statement and attention check questions) to enhance the internal validity by preventing and detecting cheating or random responses. This method can be deployed through any commonly available online software. It offers a simple and cost-effective way to collect data online – which fits the increasing need to carry out research in virtual and online environments.
Text as signal. A tutorial with case studies focusing on social media (Twitter)

Published: July 2022

AbstractSentiment analysis is the automated coding of emotions expressed in text. Sentiment analysis and other types of analyses focusing on the automatic coding of textual documents are increasingly popular in psychology and computer science. However, the potential of treating automatically coded text collected with regular sampling intervals as a signal is currently overlooked. We use the phrase "text as signal" to refer to the application of signal processing techniques to coded textual documents sampled with regularity. In order to illustrate the potential of treating text as signal, we introduce the reader to a variety of such techniques in a tutorial with two case studies in the realm of social media analysis. First, we apply finite response impulse filtering to emotion-coded tweets posted during the US Election Week of 2020 and discuss the visualization of the resulting variation in the filtered signal. We use changepoint detection to highlight the important changes in the emotional signals. Then we examine data interpolation, analysis of periodicity via the fast Fourier transform (FFT), and FFT filtering to personal value-coded tweets from November 2019 to October 2020 and link the variation in the filtered signal to some of the epoch-defining events occurring during this period. Finally, we use block bootstrapping to estimate the variability/uncertainty in the resulting filtered signals. After working through the tutorial, the readers will understand the basics of signal processing to analyze regularly sampled coded text.
