Analysis Thermal Behavior of a Locally Heated Solar Chimney
No full textThis paper presents the thermal behavior of a partially heated solar chimney under hot-humid climate conditions. The solar chimney (SCH) is 2 m high and 0.8 m wide and consists of an absorber plate and a translucent plate. The SCH allows a cavity thickness variation from 0 to 0.28 m, an inclination angle variation from 0 to 90º, and allows varying the amount of energy absorbed by the absorber plate and translucent plate. These plates were heated by resistors, simulating a solar irradiance range of 225 to 900 W/m2 (absorber plate) and from 12.15 to 50 W/m2 (translucent plate). Twelve tests were conducted with different configurations varying the power supplied to both plates, the thickness of the absorber plate cavity, and the 90º inclination angle. The variables measured were temperature, air velocity at the inlet, and heat flow on the side walls and rear wall. As a result, a maximum air renewal of 51.43 ACH was obtained, equivalent to the air changes used in a paint booth. The results show that the partially heated solar chimney can be used as a passive ventilation system for air renewal
Effect of Foot Reflexology on Clinical Outcomes of Neonates with Hyperbilirubinemia
No full textBackground and objectives: Neonatal hyperbilirubinemia is the most common reason for admission to Neonatal Intensive Care Unit (NICU) that can progress to critical levels. So, foot reflexology is one of the most widely used treatments and it is effective not only in the treatment of illnesses but also in maintaining health. Objectives: This study aimed to determine the effect of foot reflexology on the clinical outcomes of neonates with hyperbilirubinemia.Methods: A quasi-experimental research design was utilized in this study. The study subjects were 60 neonates with hyperbilirubinemia, recruited from NICU in Assiut University Children's Hospital. They were selected randomly and divided into two groups: the study group received foot reflexology interventions and the control group received routine care. Two tools were used to collect the necessary data, which included a personal structure questionnaire and neonataloutcomes assessment sheet.Results: On the fifth day, the mean of total serum bilirubin over the study group was 7.89±1.12 mg/dl, and over the control group was 10.55±0.55 mg/dl. According to the mean of the duration of phototherapy and hospital stay, the study group was 3.86±0.86- 6.80±0.88 respectively, but over the control group was 5.33±0.75- 10.40±1.22 respectively.Conclusions: A statistically significant positive correlation between applying foot reflexology interventions and improving clinical outcomes of neonates with hyperbilirubinemia. We recommended that in-service training and education programs for neonatal nurses should be conducted on a regular basis to teach them non-pharmacological strategies such as foot reflexology techniques
Guidelines for the Development of Tourism Routes Based on Cultural Resources, Betong District, Yala Province
No full textThis article aimed to investigate guidelines for developing tourism routes based on cultural resources of Betong District, Yala Province. The data were collected through in-depth interviews with 25 representatives of the community and analyzed with content analysis. The study found that the guidelines for the development of tourism routes based on resource bases were integrating the strengths of the main cultural resource capitals, particularly natural-based and cultural-based capitals to initiate eco-cultural tourism.This type of tourism would develop three important types of tourism routes: cultural tourism, eco-tourism, and cultural-eco tourism routes in Betong.The cultural-eco tourism routes would be special interest tourism routes integrating cultural and ecological tourism in Betong. Two short-trip tour programs could be offered: half-day trips and one-day trips. The research results could be expanded into more routes of tour programs that could be linked with tourism networks in Betong to offer more choices to tourists
Gender Stratification and Changing in Gender Expectations: A comparative analysis between coeducational schools and single-sex schools in Erbil
No full textThis study explores the impact of coeducational schools on reducing gender inequality by comparing students' perspectives in coeducational and single-sex schools with similar academic levels. Seventh-grade (aged 12,13) and twelfth-grade (aged 17,18) students from three basic and three preparatory schools participate. Qualitative data is gathered through eight focused group interviews with 80 students and analyzed using coding. Quantitative data is collected through questionnaires, including students' perspectives on gender issues and controllable variables related to their home background. SPSS program is used for analysis, employing cross-tabulation and correlation. The study supports the "enlightenment approach" as both types of schools show changes in gender expectations, with twelfth-grade students exhibiting more egalitarian views. Gender inequality in teacher treatment was observed in all selected schools. Preparatory coeducational schools showed better treatment towards girls, while twelfth-grade girls faced inequality in a preparatory single-sex school for girls. Similarly, a significant gender inequality was found in teacher treatment towards boy students in the preparatory school for boys. This indicates that the school somewhat reproduces inequality. In analyzing the questionnaire, gender, age, and school type were compared as independent variables with dependent variables related to students' perspectives. Results showed that girls generally hold more egalitarian perspectives than males, older students are more egalitarian than younger students, and students in coeducational schools are more egalitarian than those in single-sex schools. This suggests that coeducation is a step towards gender equality. Furthermore, a comparison between seventh-grade and twelfth-grade students' perspectives in each selected school revealed changes in gender expectations between these two stages, emphasizing the impact of education on enlightening gender equality. However, when comparing students' perspectives with their home background, the impact of the school becomes less apparent. Despite the influence of school or education on gender expectations, home socialization remains the primary factor in increasing or reducing gender inequality

A Multi Document Summarization of Learning Materials using Bigram Embedding Technique and Integer Linear Programming
No full textIn the present era of the Internet, teachers and learners are heavily inclined to use e-learning systems for an efficient learning process. Due to the proliferation of educational text contents in these e-learning systems, the need for incorporating advanced text analysis tools and techniques are becoming inevitable. Multi Document Summarization (MDS) is a technique for producing concise summaries from a collection of related text documents. The usage of MDS in the context of e-learning is more promising for providing summaries for learning materials which helps students and teachers to focus on key concepts of the learning materials. In this paper a semantic approach towards the learning material summarization is proposed based on bigram embedding and ILP technique. This approach considers bigram as the basic meaningful semantic unit of the sentences to understand and summarize documents. Embedding techniques are employed to learn the vector representation of phrases to semantically identify similar phrases to reduce the redundancy and improving coherence. Using ILP technique, the summaries were generated by selecting important sentences while reducing the redundancy using phrase vectors. Experimental results on newly created educational dataset (EduSumm) shows better performance compared to the baseline systems
Calculation of Structures Lying On an Anisotropic Basis
No full textThe definition of the nucleus and the influence function of a transversally isotropic half-space is considered. Expressions of deflection and internal forces in an infinite base plate are obtained, taking into account their deepening into the rock mass, as well as the effect of the anisotropy of the base on the distribution of deflections and internal forces. The results obtained serve as a reference for the reconciliation of the results obtained by numerical and computer methods. This calculation algorithm allows us to estimate the bearing capacity of an anisotropic soil base
Molecular Diversity Analysis of Traditional Rice Varieties (TRVs) in Nueva Vizcaya, Philippines
No full textTraditional rice varieties (TRVs) are valued genetic resources because they contain important economic value traits needed to integrate and broaden rice's genetic pool and variability. In this study, twenty-seven TRVs including a check variety (Mindanao – RS25) collected from different locations in Nueva Vizcaya, were subjected to DNA analysis to explore the genetic diversity of the collection and to determine possible aromatic TRVs in the presence of the fgr-gene. TRVs demonstrate high genetic diversity based on the relatively low similarity coefficient of 0.12 using 15 robust short tandem repeat (STR) markers. The molecular diversity analysis divided TRVs into two major clusters/groups with eight sub-clusters. Cluster I comprised 15 TRVs along with the check variety, mostly grown in high altitudes/elevation (>500masl) or cooler climatic conditions, the japonica types. Furthermore, in Cluster II, 12 TRVs were commonly cultivated at lower elevations (100-500 masl) or warmer climatic conditions (indica sub-species). Moreover, the presence of the fgr-gene allele was observed in TRVs assessed at both production sites. Finally, the province of Nueva Vizcaya had a preliminary characterization and initial conservation of its TRVs, in which these diverse germplasms could offer a valuable gene pool and rare traits for future varietal improvement programs in rice
Biodegradation of Natural Rubber Wastewater in the Submerged Membrane Bioreactor by Pichia Guilliermondii and Yarrowia Lipolytica
Get PDFAbstracts: Despite the many services that natural rubber provides to humanity, its production generates significant quantities of polluted effluents which have a negative impact on health and the environment. In order to reduce this pollution and allow water to be reused after treatment, a synthetic effluent treatment trial was carried out in a submerged membrane bioreactor in the presence of two strains of yeast (Yarrowia lipolytica, Pichia guilliermondii) and biodegradation parameters (COD, NH4+, NO2-, NO3-) were followed. The Mohlman Index (MI), the particle size distribution, the Lowry method for proteins and the Dubois method for sugars have made it possible to characterize the sludge generated during biodegradation. It appears from these experiments that the reduction rate of COD was 98% and that of nitrification and denitrification 90%. There is a decreasing linear relationship between the MI and SS (Suspended Solids) with an R2 of 95%. The distribution of the particle size of the sludge is tri-modal with a maximum of sludge having an average size of 1000 µm. The sludge formed resists filtration with a polysaccharide/protein ratio of 0.45
