P1, N170, and N250 Event-related Potential Components Reflect Temporal Perception Processing in Face and Body Personal Identification
Authors: Tanaka Hideaki , Jiang Peilun
Published: April 2024

Human faces and bodies represent various socially important signals. Although adults encounter numerous new people in daily life, they can recognize hundreds to thousands of different individuals. However, the neural mechanisms that differentiate one person from another person are unclear. This study aimed to clarify the temporal dynamics of the cognitive processes of face and body personal identification using face-sensitive ERP components (P1, N170, and N250). The present study performed three blocks (face–face, face–body, and body–body) of different ERP adaptation paradigms. Furthermore, in the above three blocks, ERP components were used to compare brain biomarkers under three conditions (same person, different person of the same sex, and different person of the opposite sex). The results showed that the P1 amplitude for the face–face block was significantly greater than that for the body–body block, that the N170 amplitude for a different person of the same sex condition was greater than that for the same person condition in the right hemisphere only, and that the N250 amplitude gradually increased as the degree of face and body sex–social categorization grew closer (i.e., same person condition > different person of the same sex condition > different person of the opposite sex condition). These results suggest that early processing of the face and body processes the face and body separately and that structural encoding and personal identification of the face and body process the face and body collaboratively.
A matter of time? Gender and ethnic inequality in the academic publishing careers of Dutch Ph.D.s
Authors: Mulders Anne Maaike , Hofstra Bas , Tolsma Jochem
Published: April 2024

Women and ethnic minorities underpopulate influential academic positions, even though these groups are increasingly represented at the doctorate level. Does this imply that gender and ethnic gaps in academic careers are closing? Prior studies on gender inequality in academia predominantly focus on single academic fields or restricted time periods. Longitudinal descriptions of ethnic inequality are even more rare. Using a novel data set of a nearly complete population of doctorates (N = 95,130) from Dutch universities across all academic fields between 1990 and 2021, and their publications, we extend descriptions on gender and ethnic inequality in academic publication careers in the Netherlands. Furthermore, we assess trends in inequality over approximately 30 years without focusing on established academics. We find that while women are as likely as men to start an academic publishing career after obtaining a doctorate, their careers are shorter. Ethnic minority scholars are less likely to start an academic career after their doctorate, and when they do, they stop sooner than ethnic majority researchers. We do not observe a trend towards more equality in academic publishing careers. In conclusion, efforts to increase diversity in Dutch academia have not yet paid off, and gender and ethnic parity are likely not just a matter of time.

Published: April 2024

Maderas Rainforest Conservancy (MRC) is a conservation non-profit organization that protects forests, offers primate field schools, and leads community outreach initiatives at sites in Central America, including La Suerte Biological Research Station (LSBRS) in Costa Rica. In 2018, MRC started Aula Verde, a conservation education initiative for elementary school students aged 5-12 at LSBRS. Groups of children from elementary schools and communities located within 50 km have visited LSBRS from 2018-2023 to participate in the 1.5-2 hour Aula Verde workshop, which consists of (1) an interactive lecture on conservation, (2) a guided forest walk, and (3) a snack, gift bag, and tree seedling for each participant. Workshops are funded by international donations to MRC and cost US $8-16 per student. Aula Verde has been successful, with multiple schools and communities making repeat visits, students’ families beginning to recycle their garbage and joining a WhatsApp group about conservation education that MRC staff initiated and lead, and teachers reporting improved learning outcomes for students who participate in the workshops. The success of Aula Verde is largely due to the ecological expertise and strong community ties of LSBRS staff. While the COVID-19 pandemic decreased Aula Verde offerings from 2020-2023, we expect workshops to resume at full capacity in 2024. In the future, MRC hopes to expand Aula Verde’s outreach to all children aged 5-12 living within 50 km of LSBRS.
Dositheos and Theodosios, and Other Greek theos-Names in a Jewish Context in Greco-Roman Egypt
Authors: Clarysse Willy , Broux Yanne
Published: April 2024

It has long been noted that theos-names have a strong connection with the Jewish diaspora in Egypt. In this article, we look at two of the most common names of this type, Dositheos and Theodosios, and the practice of garbling the orthography of these names, as -θης for Dositheos, and Θη-, Θευ-, and Τευ- for names starting with Θεο-. We propose a link with a growing avoidance in the Roman period of the use of the name of Jahweh.
Are there new biomarkers of the gastroduodenal microbiota useful in the diagnosis of coeliac disease in children? A pilot study
Authors: Salamon D. , Kowalska-Duplaga K. , Krawczyk A. , Duplaga M. , Gurgul A. , Gosiewski T.
Published: April 2024

The changing of microbiome could precede the development of coeliac disease (CeD). We compared the bacterial profile of microbiota of tissues collected simultaneously from the stomach and duodenum in newly diagnosed patients with CeD. Biopsies were collected from 60 children and adolescents aged 2-18 years: (1) 40 patients with CeD; (2) 20 children as control group. The evaluation of the bacterial microbiota was carried out by sequencing the V3-V4 regions of the 16S rRNA subunit, using next-generation sequencing (NGS). The composition of bacterial microbiota was correlated with clinical and blood parameters. The beta diversity analysis revealed a significant dissimilarity in the gastric samples between the CeD and control group (Bray-Curtis index, P = 0.008, and weighted UniFrac distance, P = 0.024). At L2 (phylum level), Campylobacterota was only present in the stomach of the CeD group. A comparison of the abundance of bacteria between the stomach and duodenum showed significant differences in 10 OTUs (operational taxonomic units) in the control and 9 OTUs in the CeD group at L6 (genus) and in 8 OTUs and in 6 OTUs, respectively, at L7 (species). A significant correlation was observed between the genus Novosphingobium in stomach of CeD group and possession of the DQ2.5 and DQ 8 allele, and in the duodenum – between the DQ 8 allele and the species Blautia wexlerae. Significant differences in selected, little-known genera of bacteria suggest their potential role as new biomarkers in the development of CeD. To fully understand the mechanism of CeD development in genetically predisposed individuals, it is necessary to take into account not only the abundance of a given genus or species of bacteria, but also the anatomical location of its occurrence.
Four-Stroke Apparent Motion Can Effectively Induce Visual Self-Motion Perception: an Examination Using Expanding, Rotating, and Translating Motion
Authors: Nakamura Shinji
Published: April 2024

The current investigation examined whether visual motion without continuous visual displacement could effectively induce self-motion perception (vection). Four-stroke apparent motions (4SAM) were employed in the experiments as visual inducers. The 4SAM pattern contained luminance-defined motion energy equivalent to the real motion pattern, and the participants perceived unidirectional motion according to the motion energy but without displacements (the visual elements flickered on the spot). The experiments revealed that the 4SAM stimulus could effectively induce vection in the horizontal, expanding, or rotational directions, although its strength was significantly weaker than that induced by the real-motion stimulus. This result suggests that visual displacement is not essential, and the luminance-defined motion energy and/or the resulting perceived motion of the visual inducer would be sufficient for inducing visual self-motion perception. Conversely, when the 4SAM and real-motion patterns were presented simultaneously, self-motion perception was mainly determined in accordance with real motion, suggesting that the real-motion stimulus is a predominant determinant of vection. These research outcomes may be worthy of considering the perceptual and neurological mechanisms underlying self-motion perception.
New Findings in the Stability Analysis of PI-state Controlled Systems with Actuator Saturation
Authors: Nuss Uwe
Published: April 2024

In this paper, a simple, generally valid stability proof for an anti-windup method for PI-state controlled systems is presented, with which it is possible to directly conclude the stability of the PI-state controlled system from a stable P-state controlled system with constraints in the manipulated variables, i.e. without having to perform a separate stability investigation of the anti-windup measures. The technique presented is based on the system description by means of state equations and Lyapunov's Direct Method using quadratic Lyapunov functions. Furthermore, the PI-state controller is designed in such a way that it provides the same command response as the P-state controller, for which a stability statement is already available. Both continuous-time and discrete-time systems are considered, which, apart from the saturation of the manipulated variables, show linear, time-invariant behavior. In addition, a general stability proof is given for discrete-time systems, which makes it possible to establish stable anti-windup methods for P- and PI-state controlled systems, which contain dead time elements in the path of the manipulated variables, without having to carry out separate stability investigations for them. For this purpose, the state controller design for the system with dead time elements in the manipulated variable paths is based on the principle that the same characteristics of the control behavior should be achieved as for the system without such dead time elements, but delayed by the dead time. The effectiveness of the presented methods is illustrated by an example from the field of electrical drives.
Application of Free Ball Check Valve Mixed Grouting Device
Authors: Liu Yifang
Published: April 2024

In recent years, due to the uneven water abundance of the aquifer and the complexity of the underground seepage field, the grouting reconstruction project of coal mining enterprises is more difficult. The previous method is to install a high-pressure ball valve before the grouting pipe connected to the grouting pump is connected to the mixing device, which can be manually adjusted when the number of grouting pumps needs to be changed. However, under certain pressure, the ordinary high-pressure ball valve often fails due to the influence of high-pressure mixed slurry, cement solidification and wear, and the number of grouting pumps cannot be increased or decreased in real time. In order to solve the problem that the mixing device of traditional grouting system is easy to fail by using ordinary high-pressure ball valve, the mixing device of free ball check valve was developed and applied in the process of treating the Ordovician limestone aquifer area on the floor of No.9 coal seam in Xipang Well. The practical results show that the pipeline can be automatically closed when a single grouting pump stops grouting, and there is no need to flush the grouting pipeline with a large amount of water, which can improve the grouting efficiency and quality, and the influence time of single hole section is reduced from 8.25h to 0.34h. The process performance can meet the requirements of efficient grouting.
Some Old Globular Clusters (and Stars) Inferring That the Universe Is Older Than Commonly Accepted
Authors: Llorente de Andrés Félix
Published: April 2024

The James Webb Space Telescope (JWST) has made startling discoveries regarding the early universe. It has revealed galaxies as soon as 300 million years after the Big Bang, challenging current galaxy formation models. Additionally, it has identified massive, bright galaxies in the young universe, contradicting the standard ΛCDM model's age estimate of 13.8 Gyr. This prompts a re-evaluation of galaxy formation and cosmological models. There is a strong tension between JWST high-redshift galaxy observations and Planck Cosmic Microwave Background (CMB) satellite measurements. Even alternative cosmological models, including those incorporating dark matter–baryon interaction, f(R) gravity, and dynamical dark have failed to resolve this tension. One possible solution is that the Universe's age exceeds predictions by the ΛCDM model. The study challenges this by introducing a method based on blue straggler stars (BSs) within GCs, comparing ages with other models. The ages obtained are compared with those of other models to certify that they are equally valid. These values are comparable within the error ranges except for the clusters: NGC104, NGC 5634, IC 4499, NGC 6273 and NGC 4833, finding their respective ages to be between 14.7 and 21.6 Gyr, surpassing the commonly accepted age of the Universe. These results inferred an age for the Universe of around 26 Gyr, close to 26.7 Gyr. This value aligns that suggested by the cosmological model named Covarying Coupling Constants + TL (CCC+TL). Such a value is consistent with early universe observations from the James Webb Space Telescope (JWST). The results of the present paper reinforces the advocating for a critical review of models encompassing dark mass, dark energy, and the dynamics of the Universe, particularly in explaining the presence of primitive massive galaxies, very old GCs, and very old and poor metallic stars.
Twisting: An Innovative Combination of Coil and Slab Building Techniques in Ceramic Art
Authors: Yussif Abdul-Rauf
Published: April 2024

This work seeks to create decorative ceramics wares which would be self-decorating to reduce the time of attention given to the surface of ceramics wares by incorporating twisting and weaving techniques into the production of the wares by drawing my inspiration from the climbing plant. Two hand forming techniques namely slab making and coiling were successfully combined to create twisted and woven wares. It also seeks to demonstrate how clay can be twisted and woven into intricate shapes for outdoor decorations. These twisted and woven wares reduced the tendency of cutting and incising as an afterthought finishing but forms an integral part of the work. Production of the wares were based on the basic units’ formation as the building blocks which were pre-formed and allowed to get leather hard and joined together in the building process. It looked at the possibility of providing an alternative to the conventional way of building ceramic wares, particularly the solidness in their form; so as to break the monotony of sold form production and present forms with surfaces which are with self-decorative appeal. There are about seven forming techniques I have experienced in ceramic art, and still counting, namely Pinching, Slab making, Coiling, Wheel Throwing, Slip Casting, Jiggering, Jollying, Ram Press, Modeling and Sculpting. The above basic techniques allows both learners and master ceramic artist to explore hand building creativity and come out with fascinating ceramics or pottery wares. My technique of production is what I term as twisting and my style as twistism, which I developed from the combination of two hand formations methods, namely, slab forming and coil making. As happened in painting, where a group of painters lead by Pablo Picasso in 1907, pronounced monotony on the line and style of painting at that time, in the late twentieth century and brought about “cubism”, so do I feel and seeks to digress from tradition to bring about forming variation, which I termed as “twistism” in ceramics, whereas the attention will be on how to manipulate the clay by twisting strips of slabs and creating non solid forms out of that as well as weaving coils to produce ceramic wares. I therefore put forward for the acceptance and inclusion of this technique, twisting as a basic forming technique in addition to pinching, slab making and coiling.

These publications will effectively resolve taxonomic nomenclature confusion in a scientific manner and establish a solid foundation for evolutionary system research within the family Bambusaceae.
A Mathematical Model of Lassa Fever Transmission and Control in Ebonyi State, Nigeria
Authors: Aloke Sunday , Okpara Patrick
Published: April 2024

Lassa virus is transmitted from rodents to humans, but it is not known whether humans can transmit Lassa fever to rats. The virus is thought to spread to humans through contact with contaminated food or surfaces. Other forms of infection include handling rodents for food (people often get rodent blood and urine on their hands) and bites. It can also spread through the use of contaminated medical equipment, such as reusing needles. The state variables of the Lassa Fever model equation is expressed as nonlinear ordinary differential equations in the technique of an initial value problem (IVP) having 10 parameters. As a result of measuring the spread of Lassa fever and determining the stability equilibrium, Lassa fever was found to be stable at an equilibrium point ε0 for which the basic reproduction number R0< 1. This paper optimized three control measures as a means to limit the spread of Lassa fever. The first two measures - regular hand washing and keeping homes and environment clean reduced the rate and impact of transmission between rodents and humans and the treatment of Lassa fever patients reduce transmission to human hosts, which were achieved by the operation of Pontryagin’s Maximum Principle. Therefore, the results of this study demonstrate that the joint control measures adopted in this paper are effective strategies to combat the spread of disease.

Published: April 2024

The low productivity of common beans is attached to many yield constraints such as lack of improved varieties; poor management practices, biotic and abiotic factors. This study was conducted to evaluate the performance of improved common bean varieties for yield and yield related traits in the Sekoru district of the Jimma zone and identify high-yielding varieties for the study area. Eleven released and one local common bean variety were tested in two locations (Yero Sekoru and Inkure), using a randomized complete block design with three replications. Data were collected for 12 quantitative traits and subjected to analysis using SAS software. The interaction effect of genotype by location showed a highly significant variation for all traits except for plant height, dry biomass yield, and hundred seed weight. The phenotypic coefficient of variation was higher than the genotypic coefficient of variation for all traits. Higher The phenotypic coefficient of variation was recorded for 100 seed weight (52.78), pod length (28.9), pods per plant (27.63), harvest index (25.94) and seed yield (24.6) and also a high genotypic coefficient of variance (GCV) was observed for 100 seed weight (20.24) and pods per plant (20.34). Low (20) and high (93.5) heritability in broad sense were recorded in days to 50% flowering and dry biomass yield, respectively. At the phenotypic level, all traits had a positive phenotypic significant correlation with seed yield per hectare except for primary branches per plant day to 95% physiological maturity and hundred seed weight, while a negative significant correlation with seed yield per hectare was observed for days to 50% flowering. Genotypic path coefficient analysis indicates that the traits studied showed a positive direct effect on seed yield per hectare, while plant height, primary branches and secondary branches per plant, days to 50% flowering, days to 95% physiological maturity and 100 seed weight exhibited a negative direct effect. However, a positive direct phenotypic effect was observed for traits such as dry biomass yield, pod length, primary branches per plant, seeds per pod, and days to 95% physiological maturity. Among the varieties tested in both locations, the highest yield was recorded for the Ser119 variety (2865.2 kg/ha) followed by the Ser125 variety (2699.2 kg/ha). Therefore, recommending these varieties to farmers in the study area is very important to increase production and income.

Published: April 2024

The basis of the conducted research was the goal of modifying composite gypsum-containing binders for the manufacture of wall products with increased water resistance, strength, frost resistance, and durability by developing a hydrophobizing solution for processing products based on gypsum binder. The article presents the results of research on the modification of artificial gypsum stone with a developed hydrophobizing chemical solution based on calcium polysulfide and titanium dioxide. Comparative indicators of water absorption of original and solution-impregnated samples, which were exposed to the frontal influence of water, are given. The water absorption of the modified samples is within 9...21% and does not change after the frontal impact of rain. Indicators of chemical resistance of impregnated samples in solutions of magnesium sulfate, urea, acetic and oxalic acids, which are characteristic components for aggressive environments of livestock complexes, food and chemical industry, are presented. The test results of the samples showed that the developed chemical solution provides a chemical resistance factor of 0.7, that is, they are chemically stable in such environments. It is shown that, depending on the number of applied layers of the solution or the time of impregnation, hydrophobization gives high indicators of the softening coefficient of the products, which is in the range of 0.6...0.82. The research results showed that thanks to the developed hydrophobizing solution, the construction and technical characteristics of the artificial gypsum stone are significantly increased. Wall products made of this material have high operational characteristics, and it is advisable to use them both indoors and outdoors.

Published: April 2024

Survivin is an important member of the apoptosis inhibitory protein family, which plays an important role in suppressing apoptosis, promoting proliferation and vascular formation. The occurrence and development of tumors are related to apoptosis and imbalance of proliferation. Gastric cancer is the most common malignant tumor in the digestive system. Due to the inadequate symptoms of early symptoms, most of them have entered the middle and late stages during diagnosis. It is easy to relapse and metastasize. The mortality rate is high, which seriously endangers human health. Research have found that Survivin expresses high in gastric cancer tissue, participating in the proliferation of tumor cells, inhibiting apoptosis and the formation of blood vessels, and is of great significance to the diagnosis, judgment transfer and prognosis evaluation of gastric cancer, especially the value of combined with a number of indicators is greater. Therefore, finding an early diagnosis and judging the ideal tumor logo combination of the early diagnosis and judgment of the prognosis is important. This article reviews the biological characteristics of Survivin and its research progress in gastric cancer, so as to provide theoretical basis for the diagnosis of gastric cancer and new ideas for the successful prevention and treatment of tumors.
Robust Analysis of the Influencing Factors for Hospitalization Costs of Senile Cataracts Patients in Chengdu Considering Different Types of Insurance
Authors: Tian Haitao , Li Tianjun , Lu Shiqi
Published: April 2024

Chengdu is one of the earliest pilot cities for urban-rural basic medical insurance integration in China. This study aimed to analyze the influencing factors of hospitalization costs of senile cataract in a tertiary hospital in Chengdu by robust method, especially considering the influence of medical insurance type. A total of 1310 discharged patients from a tertiary hospital from January 2020 to June 2021 who were mainly diagnosed with senile cataracts were selected as the research subjects. Kruskal-Wallis H test and Spearman correlation analysis are used to conduct univariate statistical analysis. The robust multivariate linear regression model and a semi-parametric multivariate regression model are established to obtain the influencing factors for their hospitalization costs. The robust multivariate regression model results show that reimbursement ratio, number of surgeries, type of medical insurance, hospitalization days, number of additional diagnoses and material proportion have significant correlations with the response variable, i.e. total hospitalization costs of the senile cataract patients. In the robust multivariate regression analysis, the type of insurance is significantly associated with the hospitalization costs. Fixing other variables, the hospitalization costs of patients with UEBMI insurance were 7.6% higher than those with URRBMI insurance. Generalized additive model (GAM) can express the nonlinear relationship between explanatory variables and response variable. Because of the nonlinear part of the GAM, the interpretation and description of the model can provide more knowledge than the linear models. In the GAM model, the type of insurance is also significantly related to the total costs. According to the regression effects of reimbursement ratio, number of surgeries, type of medical insurance, hospitalization days, number of additional diagnoses and material proportion on total costs, the paper aims to provide some references for promoting the reform of the local medical system and improving the eye health status and quality of life of middle-aged and elderly groups.
Factors Associated with the Prevalence of Bovine Tuberculosis in the Kafue Basin of Zambia
Authors: Mwelaisha Kalenga , Likwa Rosemary , Simukoko Humphrey
Published: April 2024

Worldwide, bovine tuberculosis is most common in agricultural regions of Central and South America, Sub-Saharan Africa and South-Western Asia. Bovine tuberculosis was reported to be endemic in the Zambian traditional cattle sector with a high herd prevalence of 49.8% recorded from areas within, and adjacent to the Kafue Basin as far back as 1995. An analytical cross sectional study design was applied to a sample size of 384 selected cattle owners in the Kafue Basin. A semi-structured questionnaire was administered to the cattle owners who were randomly selected. The data was analyzed using STATA Version 15 Software. The results from the study showed that 54% of the cattle owners experienced bovine tuberculosis among their cattle while 46% did not experience bovine tuberculosis. The prevalence of bovine tuberculosis in cattle was higher among the male cattle owners (76%) compared to female cattle owners (24%). There was a significant relationship of p value < 0.029 between level of knowledge of cattle owners and the prevalence of bovine tuberculosis. Unemployed cattle owners had higher odds of experiencing bovine tuberculosis among their cattle (OR 3.488; 95% CI 1.341-9.067) and the relationship was statistically significant at p value < 0.010. There was equally a significant relationship of p value < 0.042 between vaccination status of animals and the occurrence of bovine tuberculosis. The study showed that the majority of cattle owners lacked awareness and had a lower level of understanding of the disease and its public health significance. Therefore, the implications of the study suggest the creation of disease control programs that will ensure regular herd testing for bovine tuberculosis, routine vaccinations of animals, deliberate quarantine of infected animals as well as community health education about transmission, control and prevention of the disease.

Social engineering, on the other hand, presents weaknesses that are difficult to directly quantify in penetration testing. The majority of expert social engineers utilize phishing and adware tactics to convince victims to provide information voluntarily. Social Engineering (SE) in social media has a similar structural layout to regular postings but has a malevolent intrinsic purpose. Recurrent Neural Network-Long Short-Term Memory (RNN-LSTM) was used to train a novel SE model to recognize covert SE threats in communications on social networks. The dataset includes a variety of posts, including text, images, and videos. It was compiled over a period of several months and was carefully curated to ensure that it is representative of the types of content that is typically posted on social media. First, by using domain heuristics, the social engineering assaults detection (SEAD) pipeline is intended to weed out social posts with malevolent intent. After tokenizing each social media post into sentences, each post is examined using a sentiment analyzer to determine whether it is a training data normal or an abnormality. Subsequently, an RNN-LSTM model is trained to detect five categories of social engineering assaults, some of which may involve information-gathering signals. Comparing the experimental findings to the ground truth labeled by network experts, the SEA model achieved 0.82 classification precision and 0.79 recall.

Persistent Epstein Baar Virus (EBV) infection may be a perfect target for the treatment of EBV-associated lymphomas and improved patient outcomes. The aim of this work was to evaluate the frequency of LMP1 (Latence membrane Protein 1) expression in pediatric lymphomas in Dakar. Material and Methods: This was a retrospective, descriptive study from January 1, 2015 to December 31, 2020. It was based on blocks and anatomopathological reports of pediatric Lymphomas in 04 ACP laboratories in Dakar. The immunohistochemical study was carried out at the IBN ROCHD Hospital in Casablanca, Morocco, using a manual method. LMP1 immunostaining was considered positive if 10% of tumour cells showed cytoplasmic staining. Results: Positive staining for LMP1 was noted in 13 of the 42 cases of pediatric lymphomas tested, i.e. 31% of cases. These included 09 cases of Hodgkin's lymphoma, i.e. 69% (9/13), and 04 cases of non-Hodgkin's lymphoma, i.e. 31%. LMP1-positive classical Hodgkin's lymphomas accounted for 40.09% (9/22) of Hodgkin's lymphomas, and were of the mixed cellularity (6/22) and scleronodular (3/22) subtypes. The frequency of LMP1-positive samples in non-Hodgkin's lymphomas was 20% (4/20). These included 3 cases of Burkitt's lymphoma and 1 case of diffuse large B-cell lymphoma. Conclusion: The frequency of EBV infection in pediatric lymphomas in Senegal is lower than in endemic areas of Africa.

Introduction: Drug abuse is a significant public health concern among adolescents, who are a very susceptible group. This study aimed to identify the various factors associated with drug use among adolescents in secondary school. Methodology: Between October 2022 and April 2023, a cross-sectional and analytical study was carried out among adolescents in fourteen secondary schools in the city of Yaoundé, the administrative capital of Cameroon. The sampling was consecutive and non-exhaustive. The SPSS software version 23.0 was used for data analysis. Multivariate analysis was achieved using the logistic regression model. An Odd Ratio with a 95% confidence interval was used to establish associated factors. The association between categorical variables was measured using Chi-square and Fisher's exact tests (p < 0.05). Results: Of the 1987 adolescents included, the prevalence of drug use was 27.5%, i.e. 546 pupils with an average age of 16.9 ± 1.4 years. The prevalence of drug use in the study was 27.5%. The risk factors identified were students aged 15 to 18, being in the first and final year of secondary school, being raised by either their father or grandparents only and having a bar at home. The protective factor was the absence of drug use by a household member. Conclusion: The high prevalence of drug use among teenagers at school means that preventive measures need to be instilled for school health and the community.

During drilling operations, the use of drilling fluid plays a critical role, and over time, there has been considerable interest in enhancing drilling fluid characteristics in order to improve performance, reduce costs, and prevent environmental pollution. Deviating from conventional additives, recent studies have explored the use of alternative materials, as drilling fluid additives. In line with this trend, this study focuses on the laboratory investigation of the rheological and filtration properties of water-based drilling fluid treated with Palm Kernel Shell Powder (PKSP) with high viscosity polyanionic cellulose (PAC HV), used as control. To assess the impact of PKSP in water-based mud, experiments were carried out using concentrations spanning from 0.5g to 2.5g, temperatures of 27°C, 40°C, 60°C, and 80°C, and aging of 24, 48, and 72 hours. From the results the plastic viscosity of mud samples treated with PKSP were temperature dependent and also with increasing aging. The addition of PKSP showed improved performance in terms of reducing the filtrate volume as well as the cake thickness with increasing concentration of the additives, and the concentration that gave the best results across all aging duration was 2.5g. The mud weight and pH of all samples remained relatively constant, with no significant changes observed. However, PAC HV showed better results in all the cases of fluid loss and mud cake thickness. It could be attributed to the soluble contents in the PAC HV which increased the viscosity significantly and thus, kept the solid particles in suspension.

Road insecurity is a major challenge for the international community. The aim of this article is to take stock of the safety of users of soft modes of transport in Grand Lomé. The methodology used in this research is based, on the one hand, on the literature review in order to examine the different theories that govern the analysis of road safety issues and particularly on the safety of vulnerable users of soft modes of transport, and on the other hand, on the analysis of the realities on the ground through surveys and interviews with stakeholders. The results reveal real difficulties in getting around users of active modes of transport on the roads of Grand Lomé. The main roads do not have sidewalks and pedestrian crossings. The sidewalks that exist on some of the new roads are, for the most part, narrow and illegally occupied by businesses, which prevent users of soft modes from benefiting from them. Bike lanes are almost non-existent on the developed lanes. Following this logic, the street belongs first and foremost to motorists. Pedestrians and cyclists are guests who must negotiate their passage on the roads of Grand Lomé.
