Authors: N Saldon
Published: June 2023

Background: Menstruation is a phenomenon unique to the females. The onset of menstruation is one of the most important changes occurring among the girls during the adolescent years. Hygiene-related practices of women during menstruation are of considerable importance, as it has a health impact in terms of increased vulnerability to reproductive tract infections. A method for menstrual hygiene management, alternative to sanitary pads and tampons, is the menstrual cup. The menstrual cup is a bell-shaped device made of high- grade medical silicon, which is inserted into the vagina during menstruation. The device should be boiled once per month and can be used for 5–10 years. It collects more blood than the standard sanitary pads and is environmentally friendly with few known side. The knowledge about menstrual cup will motivate the women to start using them as it is an ecofriendly, cost effective and sustainable method and will thereby promote menstrual hygiene. The present study was aimed to assess the level of knowledge regarding menstrual cup among the women of reproductive age group. Objectives: To assess the level of knowledge regarding menstrual cup among women of reproductive age group. To determine the association between the levels of knowledge among women of reproductive age group and selected demographic variables. Methods: The research design selected for the study was descriptive design. The study was conducted among the women of reproductive age group from 18 to 45 years who visited the female medicine and female surgery out-patient department of a selected hospital, Bangalore. A structured questionnaire was used to assess the level of knowledge regarding menstrual cup. The data was analyzed using descriptive and inferential statistics. Results: The mean knowledge score was 9.04.With regards to the knowledge score in specific domains, 77% of the subjects knew what a menstrual cup is, 42% had knowledge about the action of menstrual cup, 40% of them knew how to use a menstrual cup, 37% had knowledge about the advantages of menstrual cup and 51% of them knew some facts on menstrual cup. This study result shows that 88.09% of the subjects had poor knowledge regarding 11.9% of them had average knowledge and none of them had good knowledge regarding menstrual cup. As per the statistical analysis there was no significant association between the level of knowledge and baseline variables at 0.05level of significance. The result of the study emphasizes need for

The purpose of this study was to determine the effectiveness of the electrocoagulation method in reducing turbidity, color concentration and COD levels on Jumputan wastewater treatment. The electrodes used are aluminum plates as anode and cathode. The variations of the research used were the speed of agitation and the system used (batch and intermittent system). The fixed variable used is a voltage of 3.5 volts, the 2 aluminium electrodes, and 250 ml volume of Jumputan wastewater. The results showed that the maximum turbidity degraded to 99.89% for the batch system at a contact time of 150 minutes with agitation speed of 150 rpm, and 99.97% for intermittent system at a contact time of 60 minutes with agitation speed of 150 rpm. The maximum percentage of color removal reached 58.90% for the batch system at a contact time of 90 minutes with a stirring speed of 50 rpm, and 54.74% for intermittent system at a contact time of 150 minutes with a stirring speed of 150 rpm. The electrocoagulation method could reduce 78.75% of the COD level for the batch system is and 80% for the intermittent system. The intermittent system slightly had more effect on the turbidity, color and COD reduction compared to batch system. Both batch and intermittent system got optimum turbidity and color removal on first 30 minutes of electrocoagulation process. The results prove that electrocoagulation method has been effective as an alternative to reduce COD and turbidity on Jumputan wastewater.

A biosafety assessment is a crucial first step in the management of microbial culture collection to screen and determine unexpected potential plant and human pathogenic bacteria. It is common to collect and store as many fresh culture collections from natural resources before being further evaluated for antagonist bacteria. As a result, a bulk of isolates must be preserved which required more effort and budget. Safety evaluations based on the hemolysis and hypersensitive reactions offer simple tests to ease culture collection management of antagonist bacteria. The study aimed to evaluate the safety of bacterial culture collection for their hemolysis and hypersensitive reactions. Ninety-five isolates of rhizosphere and endophytic bacterial isolates from the culture collections of the Department of Plant Protection-IPB University, Indonesian Industrial and Beverages Crops Research Institute, and Indonesian Spice and Medicinal Crops Research Institute, were evaluated their safety using the hemolysis and hypersensitive tests. The hemolysis test was conducted using blood agar media, from which isolates with a negative (?) reaction were then tested for the hypersensitivity reaction on tobacco leaves. Bacterial isolates passed from both hemolysis and hypersensitivity tests were then preserved by the lyophilization method for long-term storage of culture collection. Based on the hemolysis test, 68 out of 95 bacterial isolates (71.57%) were found to be positive (? or ?) reactions. The hypersensitive test showed that 22 of 27 negative hemolysis isolates did not trigger hypersensitivity reactions in tobacco leaves, therefore, they were preserved by lyophilization. The study indicated that a high number of bacterial isolates in the present collection, 68 positive hemolysis, and 5 hypersensitive, need to be re-evaluated due to their safety concerns. The present study highlights the importance of biosafety tests performed in an early stage before the to permanent collection of antagonist isolates.

Published: June 2023

At present, the beam-column connection system through a self-centering post-tensioned connection is currently an alternative to improve the seismic behavior in reinforced concrete buildings; by allowing its elements to have a linear behavior (no damage) in the face of displacements produced by seismic actions. This paper deals with the numerical modeling of the seismic behavior for a self-centering connection based on the Discrete Element Method (MED) is presented, with the aim of validating the hysterical response of the numerical model with an experimental test of the literature. The results demonstrated the horizontal distortions in the column, which are the product of the numerical simulation of the model subjected to a load that increases over time with 4 different stiffness coefficients. In addition, the hysteretic graph is presented as a result of the numerical simulation of the model, with an adequate stiffness coefficient and normal damping, subject to a cyclic load that is reversed as a function of time. The movement of the connection is controlled by the horizontal distortions of the column, achieving an approximate reproduction of the hysterical behavior expected in this type of connection. With the results shown, a simple bilinear hysteresis law is proposed, which allows its simplified use for its application in the modeling of reinforced concrete buildings with self-centering connections.

Published: June 2023

Introduction: Mental illness is becoming a worldwide concern with at least one in four persons suffering from mental illness in both developed and developing countries. Mental illnesses account for about 14% of the disease burden worldwide and are projected to reach 15% in the future. Readmission to psychiatric wards of patients is one of the biggest challenges in the field of psychiatry and hence reduces the quality of life of individual patients as well as increasing the years of lost life of the patients. Objective: This research aims at determining the factors influencing the readmission of mentally ill adults at Chainama Hills College Hospital (CHCH), Lusaka, Zambia. Method: This was a quantitative cross-sectional study with a sampling of 94 patients, who seek service at CHCH. The data collection was done through a validated questionnaire. The questionnaire included demographic characteristics of patients, health facility factors associated with the readmission of psychiatric patients, and patient-related factors associated with the readmission of mental patients.  Data were analyzed and processed using Statistical Package for Social Sciences (SPSS) version 25. Results: The analysis and presentation of results in this research provide relevant evidence that can be used to meet the objective of this research. The results were presented with a 5% level of significance and 95% confidence. The Pearson Chi-square test was used with a (p-value of 0.232). These results have revealed there was no significant difference between the factors influencing the readmission of mentally ill adults. Conclusion: No socio-demographic, factor was found to be strongly associated with readmission of psychiatric adult patients. Single, and unemployed patients were more frequently readmitted than the patients from other social groups. The young patients were readmitted more often than elders. Adult patients who stayed near the health facility were more likely to be readmitted than those who stayed far away. Stress had some association with readmissions.
Úloha miest pri sebaidentifikácii a priestorovej integrácii migrantov: prípad tureckých imigrantov v mestách Aachen a Hague = The role of cities in migrants’ self identification and spatial integration: the case of Turskish immigrants in Aachen and the Hague

Published: June 2023

Spatial perspectives in migration studies have mainly focused on the distribution and housing of migrant populations or the effects of different places on wellbeing. Places provide a sense of belonging and allow migrants to develop positive feelings about the locations where they live. In this article, we analyse the significance of cities in the process of migrants’ self-identification. Rather than focusing on neighbourhood or country, we point at the significance of the scale of the city. In the case of Turkish migrants, empirical results from two different cities, The Hague (The Netherlands) and Aachen (Germany), showed that a well-developed urban-related identity among migrants leads to strong positive attitudes towards the country. Despite the fact that predictors of urban-related identity differ in the two cities, we found that the effect of strong urban-related identity as a contributor to positive attitudes towards the country they live in is the same. Thus, we argue that a well-developed urban-related identity can be seen as an indicator for a higher sense of belonging’ to the country as a whole.

In this paper, we try to provide a geographic prediction model for burned forest areas, the research was done using multiple criteria to find spatial compatibility in geographic information systems (ArcGIS), basically 6 criteria have been adopted, which are the vegetation cover, the distance from inhabited areas, control centers, water sources, slope, roads and forest paths, This model was applied to the mount of Sidi Reghis in the province of Oum El- Bouaghi , which has been affected by many fires before, research shows that many areas are still vulnerable and may provide the appropriate conditions to define the crime of arson, which will be difficult to control. Although the precise identification of these areas requires a high degree of precision in the data used, this research attempts to provide a model that can be used to help decision-making and increase the willingness of authorities to deal with these behaviors. And to take proactive decisions to prevent these fires, including opening mountain trails, increasing monitoring centers, providing water sources, or trying to develop mountain areas to create more favorable conditions for settlement of tourist activities, or even the concentration of the population. The research also aims to protect the inhabitants of the city of Oum El-Bouaghi from the disastrous consequences that can be caused by fires in this mountain.

Local landscape is a part of the real world that surrounds a person from an early childhood. It offers opportunities for their cognitive development, stimuli for emotional development, shapes their views. A positive relationship with the local region should be developed in Geography education as one of the affective educational goals. The aim of this paper is to evaluate pupils' perception of the concept of a local region and to find out their relationship to their local region based on the results of a questionnaire survey of pupils of lower secondary education in the Czechia and Slovakia. The data were collected using an online questionnaire, which was completed by 4 673 pupils in the Czechia and 3 980 pupils in Slovakia. The results show that pupils perceive their local region most often as the whole district or the whole region in which they live. Pupils' attitude to the local region decreases with their age and was stronger among boys. Slovak pupils identify with their region more and there are significant differences in their relationship to the region across regions. In particular, pupils are most proud of the natural environment and cultural monuments. The findings are beneficial in the field of regional identity research, but also in educational settings, as the local region and a deeper knowledge of it is not only the goal, but also the means of Geographic education.

Multilingual individuals, who possess proficiency in multiple languages and an understanding of their structures, often engage in code-mixing as a means of communication. This study aims to explore the code-mixing patterns exhibited by Yahukimo students residing in Malang, as well as the underlying motivations for their code-mixing practices. Employing a descriptive qualitative research design, the study identifies two predominant types of code-mixing: insertion and congruent lexicalization, which are influenced by the linguistic structures of the languages involved. Additionally, the variation in code-mixing is classified into inner and outer code-mixing. The findings indicate that Yahukimo students employ code-mixing as a means of fostering solidarity and navigating social and cultural distances. This research provides valuable insights into the intricate dynamics of language use and contributes to our understanding of the phenomenon of code-mixing

Energy is an important issue in the entire world and in under-development countries especially in these regions is where the main growth of energy requirements is expected. For more than fifty years ago Ecuador has been subsidizing fuels, considering that energy prices do have a huge impact on low-income families. Cities and buildings do play a relevant role in reducing energy requirements to import energy to urban areas in order to achieve the maximum energy self-supply capability in buildings and cities. This study describes shortly recent works performed in Cuenca to decipher the energy resources available and the capability to self-supply in Cuenca, Ecuador. The main results obtained show that photovoltaics (PV) in buildings is the best option, it could supply the entire power requirements in the city, and around 22 % of the electrical requirements of industrial high-consumption buildings, also for a single-family home it is only required around 7 m2 of roof that corresponds around 10 % of a typical roof availability of a typical 2-floor house, and for higher education building it is possible to achieve the total power requirement with PV technology, but grid limitations imply limitations also to PV capability.
An Enhanced Hybrid Grid Connected Photovoltaic System Using Voltage Oriented Controller and Class D Chopper
Authors: Maamar Taleb  , Mohamed Amine Fnaiech  , Khaled Zehar
Published: June 2023

The performance of a shunt interconnection made from a PV system, a three phase grid voltage supply, and a DC shunt motor (DC load) is investigated The PV system participates with maximum powers to the overall interconnection active power flow. It uses a class D chopper circuitry controlled properly by a typical maximum power point tracker (MPPT) controller. The grid has the role of supplying active power in case of any power deficiency needed by the DC motor load. Similarly, it has also the role of absorbing active power in case of any additional power generated by the PV system and not needed by the DC load. This is done by using an AC/DC power electronic converter. The AC/DC power electronic converter operates either under rectifier or inverter modes. The AC/DC power electronic converter is also operated under the next two conditions: 1-the reactive power expected at the grid voltage bus should be nearly null, 2-harmonics currents often encountered in the grid line currents waveforms should be tolerable. The two latter conditions are fulfilled by using the principle of voltage oriented control (VOC) technique. The performance of the investigated interconnection is simulated in Matlab/Simulink platform. Quite satisfactory results are obtained. The satisfaction about the obtained simulation results persists on being able to integrate easily the PV system with the AC grid while extracting maximum power from the PVG and having a unity power factor at the AC grid bus and less encountered harmonics in the ac line currents.
