Authors: Barros Daniel Bezerra , Souza Rui Gabriel , Meirelles Gustavo , Brentan Bruno 
Published: October 2023

Abstract
Leakages in water distribution networks (WDNs) affect the hydraulic state of the entire or a large part of the network. Statistical correlation computed among pressure sensors monitoring network nodes aids the detection and localization of such leaks. This opens the possibility to work with water network databases, where graph signal processing (GSP) tools aid in understanding changes in pressure signals due to leakages in the hydraulic system. This paper presents a methodology for time-varying pressure signals on graph structures. The core of this methodology is based on changing of pressure, due to leaks, that modifies the graph structure. Computing for each time step a new topology of the graph and applying centrality analysis based on PageRank, it is possible to identify the presence of new leaks at the water system. A confusion matrix evaluates the precision of the proposed methodology on defining where and when such leakages start and end. Seven leaks are used to validate the process, which presented 86% in accuracy terms. The results show the benefits of the method in terms of speed, computational efficiency, and precision in detecting leakages.

Abstract

Ecological flow is a restrictive condition set for human water consumption in water resources management to protect river ecosystems. However, uncertainties in hydrological conditions, changes in regulatory capacity, and temporal-spatial differences bring difficulties to the implementation and supervision of ecological flows. By analyzing the relevant concept and connotation of ecological flow, it is concluded that the ecological flow regimes suitable for practical application should be a dynamic interval rather than a fixed value. Therefore, an improved ecological flow calculation method was proposed, which is to increase the feasible lifting volume for different ecological service objects based on the determined ecological baseflow. Taking two cross-sections of the Weihe River as an example, the ecological flow was calculated by comprehensively considering the factors of inflow, fish survival, landscape, and agricultural irrigation. The result shows the lifting volume occurred in the high flow season (April–June), and the maximum ecological flow of LJC and WJB cross-sections was 20.2 and 16.0 m3/s, respectively. Moreover, it is a generalized approach that can be extended to a more complicated river system, and the calculation results have reliability and adaptability in integrated water regulation.

Abstract

The extended-spectrum β-lactamase (ESBL)-producing Escherichia coli is becoming a global public health concern. More comprehensive surveillance of β-lactam resistance in E. coli would improve monitoring strategies and control resistance transmission in contaminated environments. This study investigated the prevalence of β-lactamase genes in E. coli isolated from the Seven Crater Lakes in San Pablo, Laguna, Philippines. Water samples from lakes were collected for the isolation of E. coli (n = 846) and molecular characterization by detecting the presence of the uidA gene. The isolates were then tested for the presence of β-lactamase genes using PCR. Among the screened genes, blaAmpC was the most dominant (91%). Other β-lactamase genes such as blaTEM, blaSHV, and blaCTXM were also detected with percentage occurrence of 34, 5, and 1%, respectively. Multiple genes within individual isolates were also observed, wherein blaTEM/AmpC was the most prevalent gene combination. Moreover, a significant negative correlation between blaAmpC with blaSHV and blaCTXM was depicted in this study. Overall, these findings demonstrate the presence of β-lactamase genes in E. coli in the Seven Crater Lakes of San Pablo and can be used in developing effective strategies to control antibiotic resistance in environmental waters.
Enhancing water security through site selection of water harvesting structures in semi-arid regions: a GIS-based multiple criteria decision analysis
Authors: Patel Anant , Chaudhari Nirali 
Published: October 2023

Abstract
This research endeavors to develop a decision support tool aimed at ascertaining the optimal site selection for water harvesting structures in semi-arid regions, employing a geographic information system-based multiple criteria decision analysis approach. Water scarcity poses a formidable challenge in various countries, particularly in arid and semi-arid areas. Among the potential solutions, the adoption of water harvesting technologies stands out for capturing and storing rainwater to address water shortages. However, the effectiveness and efficiency of these structures hinge significantly on their precise placement. To address this issue, this paper introduces a comprehensive framework that integrates multiple criteria, encompassing rainfall intensity, land slope, soil type, and land use, to discern the most suitable locations for water harvesting structures. A practical application of the proposed methodology is demonstrated through a case study conducted in the Sabarmati river basin. The results demonstrate the effectiveness of the approach in identifying highly suitable locations for water harvesting structures, ultimately contributing to the enhancement of water security in the region.

Published: October 2023

Comprehensive research was conducted in the mangrove ecosystem of West Muna Regency to investigate the absorption of greenhouse gas (GHG) and degradation of its litter-produced GHG emissions, including N2O and carbon. The ecosystem consisted of four stations, namely Mangrove Maginti (station I), Mangrove Tiworo Tengah (station II), Mangrove Tiworo Islands (station III), and Mangrove Sawerigadi (Station IV). The research aimed to determine emissions and global warming potential (GWP) of N2O gas resulting from the degradation of mangrove litter. The team used a syringe mounted on the hood to collect gas samples and gas chromatography for concentration analysis. The correlation of emissions to environmental variables was analyzed using the Pearson correlation method. The results showed that all species' most significant and smallest average emissions were at stations III and II, with values of 0.0019 mg/m2/hour and 0.0015 mg/m2/hour, respectively. Water temperature showed a weak relationship with N2O emissions, namely r = 0.3511 (p <0.05), while water salinity did not strongly correlate with N2O emissions (r=-0.4471; p<0.05). The average GWP value ranged from 0.3665–0.6314 CO2e mg/m2/hour. Species R. apiculata and B. cylindrica at stations III and II had the largest and smallest GWP values of 0.8392 and 0.1912 CO2e mg/m2/hour, respectively.

Published: October 2023

Abstract
This paper is devoted to the transport of slaughter animals. There are obstacles that needs to be pointed out, removed, and resolved. General requirements for the movement of slaughter animals within the Union have proven to be an unjustified administrative burden and costly. It also presents how important is to keep and follow all the rules provided by European Union to prevent any issues and keep the animals in good conditions and welfare during the transport. Bad conditions and not keeping the rules during animal transport can cause the stress of the animals and have a huge effect on their health. The stress can cause injuries and even a death of the animals that were healthy and had no signs of any sickness before the transfer. The main goal of the paper is to present the circumstances under which safe transport depends on choosing the correct logistical management, starting with the proper vehicles. Specific rules apply depending on the type and quantity of animals transported. The paper explains and summarizes the special establishment for road transport, including all mandatory actions, documents, and data centralisation (COMEX, TRACES, IMSOC).
"Indian Lady Tourists Killed at Jericho": Tourism, Pilgrimage and South-South relations in Interwar Palestine
Authors: Irving Sarah 
Published: October 2023

In press coverage of the 1927 earthquake in Palestine, frequent mention is made of the deaths of three women at the Winter Palace Hotel in Jericho. That the three were from British-occupied India apparently rendered them unusual enough to be noted by a journalist, whose observation was reproduced around the world. This article draws on newspapers, official documents and secondary literatures on the hajj, tourism and the British Empire to consider the history of South Asian travellers to Palestine and relationships between colonialism and travel in the interwar period.
One of the three women was Lady Abdul Rauf, the wife of a retired High Court judge and veteran Indian Muslim nationalist campaigner, Sir Syed Abdul Rauf. The couple had departed Bombay in April 1927 for the hajj to Mecca and Medina, but extended their trip to include Jericho. This was not unusual; the Indian Hospice in the Old City of Jerusalem attests to a long history of Indian visitors to Palestine. This paper, however, locates the ill-fated presence of Lady Abdul Rauf and her companions in the changing nature of Indian travel in the region, as religious pilgrimage to Jerusalem combined with politics and tourism, and as changing infrastructures of capitalism and colonialism shifted how Indian visitors experienced Palestine.

В работе выполнен экспериментально-теоретический анализ влияния выступающих частей в виде расположенного в горизонтальной и вертикальной плоскости кормового оперения на характер движения погруженного тела в приповерхностной водной среде и его гидродинамические характеристики. Впервые экспериментально на базе опытового бассейна получены зависимости вертикального перемещения тела, возникающего под воздействием подъемной силы, и определены углы дифферента модели при ее движении с различной скоростью. Предложен численный метод расчета, разработанный на базе программного комплекса (ПК) ANSYS 19 R2 Academic Research, позволяющий определять характер волнообразования на поверхности воды, силы и гидродинамический момент, действующие на тело с установленными в кормовой оконечности рулями со стороны жидкости при его движении в приповерхностной водной среде с различной скоростью. Выполнено сопоставление полученных результатов с данными для аналогичной модели тела, без оперения. Установлено существенное влияние на зависимости исследуемых параметров выступающих частей. Наличие рулей приводило к росту сопротивления трения и полного сопротивления. Также наблюдался рост подъемной силы действующей на тело в результате чего модель сильнее притягивалась к поверхности воды при , а при больших относительных скоростях движения сильнее отталкивалась от поверхности, чем модель без оперения. Существенное влияние наличие рулей оказывало на угол дифферента модели и на значения гидродинамического момента.

Published: October 2023

Media exposure to traumatic event can cause anxiety. One of the actions taken during COVID-19 to reduce anxiety is panic buying behavior. This study aims to determine the role of media exposure related to COVID-19 on panic buying with coronavirus anxiety as a mediator. This research is conducted in Jabodetabek from September 2021 to April 2022. The population in this study was emerging adulthood (18-25 years old) with a sample of 397 people. Sampling is done by sharing questionnaires using google form through social media. Data analysis uses multiple linear regression techniques. The results showed that most of the respondents were female (58.7%), aged 21 years (43.8%), had a final high school/vocational/equivalent education (66.2%), domiciled in Jakarta (55.2%), had no history of COVID-19 (72.5%), had a family with a history of COVID-19 (51.1%). Based on the results of the main data analysis, it was found that participants in this study had low levels of media exposure, coronavirus anxiety, and panic buying. The results of the analysis showed that there was a significant and positive partial mediation role between media exposure to panic buying with coronavirus anxiety as a mediator variable. It can be concluded that excessive media exposure related to COVID-19 can increase coronavirus anxiety and trigger the emergence of panic buying behavior. Therefore, the government or information spreaders can pay more attention to the spread of valid information to prevent the emergence of panic from rumors and false information.

Published: October 2023

The online learning process at the Kindergarten education level prevents direct interaction between teachers and children. The pattern of collaboration between parents and teachers to support the learning process has also changed. However, parental involvement in children's education is not always according to the teacher's expectations. Parental involvement is the participation of parents in the process of their children's educational experience. Teachers can perceive barriers to parental involvement in their children's education. This study aims to examine the role of teachers' perceptions of the barriers to parental involvement on the well-being of Kindergarten teachers. This study uses a non-experimental quantitative method, with purposive sampling technique to find participants who are willing to provide the information needed. The study sample numbered 67 Kindergarten teachers in Tangerang, who are actively teaching during the COVID-19 pandemic. The results show that teachers' perceptions of barriers to parental involvement have a significant role in the well-being of Kindergarten teachers, meaning that if teachers perceive barriers to parental involvement, teacher well-being is affected.
Women’s Entrepreneurial Competencies and Economic Development: A Review of Literature
Authors: John-Eke, Ebere Chika  , Gabriel, Justin Mgbechi Odinioha  
Published: October 2023

The success or failure of entrepreneurs has so much to do with the economic development, growth or lack of it in any nation. As a review paper, relevant scholarly views were put to the rigorous test of thoughts and comparisons. The key observations and extrapolations revealed that women entrepreneurs contribute significantly to Nigerian economic development through wealth creation, poverty eradication, employment generation, and basic family support, among others. Several challenges were also observed as delimiting the potential of women entrepreneurs in Nigeria, especially the issues of gender inequality, lack of access to finance, inability to gain stakeholders' confidence, technological illiteracy and decrepit infrastructure, among others. The paper concluded that entrepreneurship remains the shortest road to economic liberation for any nation and efforts must be put in place to develop and harness its tenets for the benefit of all, male and female alike. Drawing from the avalanche of reviews, we, therefore, recommend that:

Government should create more enablers for women entrepreneurs, ranging from training, improved financing, favourable policies and direct supervisory support,
Women entrepreneurs should personally upscale their basic business management skills, increase their self-efficacy and boldly take opportunities like their male counterparts or even more.

The global pharmaceutical industry is becoming increasingly prone to disruptions and economic fluctuations. In Nigeria, available records showed that pharmaceutical companies are plagued with poor employee productivity in the face of increasing competition and changes in the business environment. This study investigated the effect of strategic flexibility on employee productivity of quoted pharmaceutical companies in Nigeria.
The survey research design was adopted for the study. The research population consisted of 642 management and senior staff employees of the six quoted pharmaceutical companies in Nigeria. The study adopted total enumeration in soliciting responses from the sample population using an adapted and well-structured questionnaire. The data collected from respondents were analyzed using both descriptive and inferential (PLS-SEM) statistics.
Findings showed that strategic flexibility (coordination flexibility, futurity, reactive flexibility, resource flexibility) has a positive significant effect on employee productivity of quoted pharmaceutical companies in Nigeria. The study concluded that strategic flexibility does have a positive impact on employee productivity of quoted pharmaceutical firms in Nigeria and recommended that management of the pharmaceutical companies should pay more attention to resource flexibility, coordination flexibility, reactive flexibility and futurity in their bid to enhance employee productivity.
Role of Employability and Life Skills in Securing and Retaining Livelihood Opportunities
Authors: Dennis Gichobi Muchiri  
Published: October 2023

In today's workplace, a blend of both hard and soft skills is needed for employees to succeed, even though the latter remains overlooked. Hard skills are the job-specific abilities that workers need to perform their duties, while soft skills are the personal qualities they need to thrive in the world of work. This study postulates that learning institutions have overly inclined towards hard skills at the expense of soft 'employability' skills, thereby making those seeking to secure or progress in their jobs learn the hard way their need for such skills. The objectives were:

To study the most important factors that organizations consider while hiring or promoting workers,
To observe the common employability and life skills that employers consider while making hiring/promotion decisions, and
To assess the extent to which employability and life skills are important in securing and maintaining livelihood opportunities.

With the research seeking to answer the 'what' question rather than the 'how' or 'why,' a descriptive research design was adopted to complement an inductive reasoning approach. A mixed methodology was used to collect quantitative and qualitative data from 284 respondents from 24 counties in Kenya out of 47, who represented more than 10 sectors. The results show that employability skills constitute the main factor of consideration while hiring/promoting workers. The common employability skills include communication, time management, a positive attitude, teamwork, and decision-making. Without these soft skills, workers struggle to secure and maintain jobs at the strategic, business, and operation levels of an organization.
Titanium dioxide Ag NP enhanced solid solar cell electrodes for favourable efficiency
Authors: Njoroge David K. 
Published: October 2023

Population growth leads to a heightened demand for working potential to support modern commercial and residential evolutions. Available conventional energy sources, however, cause environmental pollution and severe health problems like global warming. The current energy sources also face challenges due to factors like global warming that make hydro-generated energy production even more difficult due to droughts. Therefore, alternative energy options need to be explored. The study in question aimed to find a cost-effective and environmentally friendly energy source by fabricating a solar cell that uses titanium dioxide and potassium iodate (mixed in carbon) layers in a solidified structure. TiO2 was chosen due to its photo-generating properties and synthetic steadiness over a spread acidity/basicity neutrality. The iodine/iodide complex was used to replenish the photo-excited electrons while graphite facilitated their migration. The researchers varied the ingredients capacities for the separate electrodes keeping the rest unvaried for improved (I-V) terminal parameters. Deduction from the research established that the (0.4:0.3:0.17:0.01) TiO2/CX:I2:KI proportions resulted in the optimum charge range generation. The inclusion of potassium iodate (KI) improved iodine solvability and facilitated even dispersal in graphite, which was maintained at 0.01 g in all cells. The absorber and receptive layer thicknesses of 2.00 mm and 1.00 mm respectively generated the best 0.979 V open-circuit voltage (Voc) and 12.037 μA short-circuit current (Isc) results. Favorable (10.46%) efficiency (η) and (0.64) fill factor (FF) were derived. Conducting transparent glass was suggested for improving the linkage to the external circuit and models of reducing air pockets in the solid TiO2 photovoltaic devices could further enhance their performance.

Published: October 2023

OBJECTIVE: To examine modifiable and nonmodifiable factors for associations with dance-related injury among preprofessional ballet dancers over 5 academic years. DESIGN: Prospective cohort study. METHODS: Full-time preprofessional ballet dancers (n = 452; 399 female; median age [range], 15 years [11-21]) participated across 5 academic years at a vocational school. Participants completed baseline screening and online weekly injury questionnaires including dance exposure (hours/week). Zero-inflated Poisson regression models were used to examine associations between potential risk factors measured at baseline and self-reported dance-related injury. RESULTS: In count model coefficients, left one leg standing score (log coefficient estimate, −0.249 [95% CI: −0.478, −0.02]; P = .033) and right unipedal dynamic balance time (log coefficient estimate, −0.0294 [95% CI: −0.048, −0.01]; P>.001) carried a protective effect with increased years of training when adjusted for Athletic Coping Skills Inventory (ACSI) score. A significant association was found for left unipedal dynamic balance time and dance-related injury (log coefficient estimate, 0.013 [95% CI: 0.000, 0.026]; P = .045) when adjusted for years of training and ACSI score. There were no significant associations between dance-related injury and ankle and hip range of motion, active straight leg raise, or Y Balance Test measures. CONCLUSION: When adjusted for years of previous dance training and psychological coping skills, there was a significant association between limb-specific lumbopelvic control and dynamic balance tasks, as well as self-reported dance-related injury in preprofessional ballet.
