Published: July 2024

For all users of the road, road safety is crucial. Everyone is concerned about it because of the dramatic increase in the number of vehicles on the road in recent years, road safety has become even more crucial. According to a 2014 World Health Organization research, motorcycle riders account for more than half of all fatalities in traffic incidents. At 19%, pedestrians make up the second-highest percentage of road user fatalities, after four-wheeled vehicle drivers (14%), and their passengers (11%). If there are road safety services in place and followed to reduce the high risk of accidents on most Philippine highways and roads, then accidents may be prevented. Many traffic incidents that occur these days include trucks, buses, and motorcyclists. Even when they are not in the official motorcycle lanes, most motorbikes would overtake as often as possible to escape heavy traffic because these vehicles tend to travel through even the steepest parts of the road. This situation may result in a collision between a motorcycle and a high-wheeled vehicle.
This study employed the descriptive developmental method of research using the questionnaire in gathering the respondents’ assessment on the road safety services of a transport safety provider.

MORPHOTYPE MATTERS: AN EXPERIMENTAL ANALYSIS OF THE MORPHOLOGICAL FIDELITY OF GASTROPOD STEINKERNS

Abstract
Gastropods are commonly preserved as steinkerns (internal casts), a mode of fossilization that leads to loss of external morphological features. This loss of information is problematic for taxonomic identification and ecological inference in evaluating assemblages where original shell material is not preserved. We seek to quantify how closely gastropod steinkerns represent the morphology of their original shells. We investigated this relationship experimentally by fabricating steinkerns in silicone from modern gastropod shells and comparing their geometry to that of the shells we used to create them. In addition to recording traces of ornamentation such as ribs and spines, we used a theoretical morphospace framework to evaluate the fidelity of shell-coiling parameters in steinkerns. Our results show that some morphotypes reflect their taxonomic identification more accurately than others, indicating that steinkern fidelity is highly variable. Experimental steinkerns consistently cluster less reliably by morphotype than their original shell counterparts. Additionally, we find that shell thickness is an important factor in determining steinkern fidelity. The fidelity of the high-spired Duplicaria duplicata, for example, is significantly lower than the average value for the morphotypes investigated whereas the fidelity of planispiral Haplotrema concavum and open-coiling Epitonium is significantly higher, a trend related to shell thickness. Thus, taxonomic identification and subsequent analyses, such as community composition, of steinkern assemblages must recognize this differential fidelity to counter preservational biases.

Authors: Ndukwani Tiyiselani , Ramhurry Runash 
Published: July 2024

The influence of modern technology and engagement in cyber socialising have become a prominent part of modern communication. A new learning pedagogy with proper guidelines is needed to assist users to engage with social networking platforms efficiently. The researcher investigated discourse analysis involving participants to answer questions about both the contextual application of the language, and the functions and results of aspects pertaining to discourse such as diction, cohesion, and metaphors. The researcher employed a quantitative approach in this study. The study randomly sampled 80 students from a University of Technology (UoT) in Gauteng to participate in quantitative discourse analysis of communication using Facebook, WhatsApp and Twitter texts. The methods of data elicitation embraced extracts from Facebook, WhatsApp and Twitter texts provided by 80 participants. Statistics were used to present the findings of the quantitative data which included mainly frequency of certain aspects pertaining to discourse. Data were collected via email and texts were numbered according to the participants. These texts remain anonymous and the identities of the participants were concealed. The study found that the language used on Facebook, WhatsApp and Twitter was characterised by the use of emoji, low register words, code-switching few spelling errors and the modern tendency to shorten words by using clipping and number homophones which are not seen as errors but a unique style of writing. Facebook, WhatsApp and Twitter remain three popular communication sites and discourse surfaces since it is important for users to communicate meaningfully even when using excessive punctuation to indicate excitement and emoji to communicate emotions.
Spill-over effects between daily and air travel behavior: a panel analysis
Authors: Kroesen Maarten , Mehdizadeh Milad 
Published: July 2024

Abstract

The existence of spill-over effects between pro-environmental behaviors has been well documented, but studies in the field of travel behavior are scarce. In this research, we explore the sign and directionality of spill-over effects between daily mode use and air travel behavior. Using data from the Netherlands Mobility Panel, we employ a twofold approach to explore these spill-over effects both cross-sectionally and longitudinally. The results of the cross-sectional latent class analysis reveal that the majority of the sample can be labeled as ‘dissonant’. For these travelers, the daily travel pattern is on the sustainable end of the spectrum (as observed in the sample), while the flying behavior is on the unsustainable end, as well as the other way around. The results of the panel analysis indicate that bicycle use has a positive bidirectional relationship with flying for private purposes, providing evidence in favor of both moral licensing and moral cleansing.

Abstract

Addressing drug-induced liver injury is crucial in drug development, often causing Phase III trial failures and market withdrawals. Traditional animal models fail to predict human liver toxicity accurately. Virtual twins of human organs present a promising solution. We introduce the Virtual Lobule, a foundational element of The Living Liver, a multi-scale liver virtual twin. This model integrates blood flow dynamics and an acetaminophen-induced injury model to predict hepatocyte injury patterns specific to patients. By incorporating metabolic zonation, our predictions align with clinical zonal hepatotoxicity observations. This methodology advances the development of a human liver virtual twin, aiding in the prediction and validation of drug-induced liver injuries.

Published: July 2024

Abstract

This study compares the solvent extraction behavior of lithium (Li) using the cost-effective extractant PC88A and the more expensive extractant HBTA. PC88A achieved an optimal extraction rate of 37.6% at pH 5.43, with a maximum rate of 41.4% at pH 7.80. It required six stages at a 5/1 O/A ratio for 98% extraction and three stages at a 15/1 ratio for 100% extraction. In contrast, HBTA showed an optimal extraction rate of 86.2% at pH 6.23 and a maximum rate of 92.9% at pH 11.95. HBTA achieved 100% extraction with three stages at a 1/1 O/A ratio and one stage at a 5/1 ratio. These findings reveal HBTA's striking superiority over PC88A in terms of efficiency. Future studies should include evaluations of equipment and extractant costs, and overall efficiency.

Abstract

The instability and collapse of the extraction borehole seriously affects the gas extraction effect, and it is of great significance to study the efficient borehole protection technology to improve the stability of the borehole and ensure the gas extraction effect. The purpose of this paper is to develop an environmentally friendly borehole protection material with high strength, high permeability and controllable setting time, and then propose a borehole synergistic protection technology for in-hole screen protection and grouting reinforcement. The foaming agent mother liquor was obtained by hydrolysis of human slag, the composite protein foaming agent was prepared by improving the compounding of the mother liquor, pulverized coal was used instead of fly ash as mineral admixture, the water-cement ratio, material ratio and foaming agent addition amount of the optimal grouting material were determined by orthogonal tests, and the foam concrete with high strength and high permeability was prepared, and its on-site construction feasibility was verified by the dynamic curing characteristics experiment of coagulation time and fluidity. Finally, the borehole synergistic protection technology of in-hole screen protection and grouting reinforcement was proposed, and industrial tests were carried out in the field. The results showed that: 1) Sodium hydroxide hydrolyzed human hair residue was used as a composite protein foaming agent mother liquor material, and the optimal foam performance was determined to be 2g/L sodium laureth sulfate (SLS) + 0.3% calcium stearate through the compound improvement experiment. 2) Pulverized coal replaces the commonly used material fly ash as concrete admixture, which can effectively use waste resources, improve the strength and durability of concrete, and reduce carbon emissions and environmental pollution. 3) The prepared hole protection material has high permeability and compressive strength, when the water-cement ratio is 0.7:1, the foam content is 25ml, the pulverized coal is 30g, the silica fume is 5g, and the polypropylene is 0.2g, the compressive strength of the material is 13.665MPa, the permeability is 2.12MD, the porosity is 22.019%, and the coagulation time is 401 minutes to 418 minutes, which meets the requirements of initial solidification within 1–3 days. The fluidity is 320mm, which is in line with the field experiment. 4) The proposed screen pipe and grouting borehole collaborative protection technology can realize the internal and external coordinated protection of the borehole, the grouting outer layer protection can be poured and solidified according to the shape of the borehole and the falling coal and rock, the inner layer protection of the screen pipe can enhance the stability of the borehole and the grouting material after solidification, effectively prevent the instability and collapse of the borehole wall, ensure the smooth borehole extraction channel, and effectively improve the gas extraction efficiency.

Published: July 2024

Abstract

Glioma is the most aggressive intracranial malignancy and is associated with poor survival rates and limited quality of life, impairing neuropsychological function and cognitive competence in survivors. The Proteasome Subunit Alpha Type-5 (PSMA5) is a multicatalytic proteinase complex that has been linked with tumor progression but is rarely reported in glioma. This study investigates the expression pattern, prognostic characteristics, and potential biological functions of PSMA5 in glioma. PSMA5 was significantly overexpressed in 28 types of cancer when compared to normal tissue. Furthermore, elevated levels of PSMA5 were observed in patients with wild-type isocitrate dehydrogenase 1 and exhibited a positive correlation with tumor grade. It was also found to be a standalone predictor of outcomes in glioma patients.Additionally, inhibiting PSMA5-induced cell cycle arrest may provide a therapeutic option for glioma.

Abstract

Indoor air pollution poses a significant environmental concern, leading to adverse health effects. Fine particulates (PM2.5) observed indoors exhibit high variability, influenced by both indoor emission sources and the infiltration of outdoor particles through open spaces and the incomplete building insulation. This study examines the relationship between indoor and outdoor PM2.5 levels using data from a network of citizen-operated low-cost air quality sensors, deployed in Legionowo, Poland. Our results showed that generally, indoor PM2.5 was lower than outdoor levels, with occasional peaks attributed to potential indoor emission sources. Statistical analysis identified emission events, particularly during cooking and household-heating periods, occurring more frequently from October to April. In the absence of indoor sources, outdoor particles accounted for 29–75% of indoor particle concentration, highlighting the significance of infiltration. This study shows how citizen-generated data using low-cost sensors, after post-processing, can provide decision-ready information as for example outdoor particulate matter infiltration factors for each building. This information can help decision-makers in devising effective interventions such as prioritizing indoor ventilation or addressing outdoor pollution sources.
