Authors: Zulfiana Indah Sari
Published: May 2021

To get good quality learning, a comfortable study room is needed both visually, audally and thermally. Thermal comfort is greatly influenced by the climatic conditions of a region. In areas with high daily air temperature, high humidity and low air velocity, it is difficult to produce thermal comfort with natural air conditioning. Jayapura City is one of the cities in Indonesia with daily air temperature and high humidity and low air velocity. Therefore, adaptive processes are needed to achieve thermal comfort in spaces, including study rooms. Each human's adaptive thermal comfort is different according to local climatic conditions. The purpose of this study was to determine the adaptive thermal comfort of students in naturally ventilated classrooms at the Jayapura University of Science and Technology (USTJ) in the city of Jayapura, Papua, namely students 'neutrality, acceptance and thermal preferences, as well as students' adaptive behavior in achieving thermal comfort. This research was conducted in one of USTJ's classrooms in Jayapura, Papua. Four environmental parameters were measured, namely temperature, humidity, wind speed, and mean radiant temperature (MRT). The data were obtained through filling out a questionnaire to 100 USTJ students during the space measurement. Thermal neutrality data were analyzed using regression analysis using SPSS software, while thermal acceptance and preference and adaptive behavior were analyzed based on the results of the questionnaire answers. The results showed that USTJ students' thermal neutrality was at 29.°C Ta or 29.55°C Top. all students can accept the thermal conditions of the room, but 59% of students choose to want the room to be cooler due to their thermal preferences. The adaptive behavior that is carried out is turning on the fan, picking up objects to be used as a fan, leaving the room and drinking more often.
A Generalization of the Blackwell–Ryll-Nardzewski Measurable Selection Theorem
Authors:   Department of Mechanics and Mathematics, Moscow State University, Afonin K.A. ,   Moscow Center for Fundamental and Applied Mathematics
Published: May 2021

One of the main forms of the measurable selection theorem is connected with the existence of the graph of a measurable mapping in a given measurable set 𝑆 in the product of two measurable spaces 𝑋 and 𝑌 . Such a graph enables one to pick a point in the section 𝑆𝑥 for each 𝑥 in 𝑋 such that the obtained mapping will be measurable. The indicated selection is called a measurable selection of the multi-valued mapping associating to the point 𝑥 the section 𝑆𝑥 , which is a set in 𝑌 . The classical theorem of Blackwell and Ryll-Nardzewski states that a Borel set 𝑆 in the product of two complete separable metric spaces contains the graph of a Borel mapping (hence admits a Borel selection) provided that there is a transition probability on this product with positive measures for all sections of 𝑆 . The main result of this paper gives a generalization to the case where only one of the two spaces is complete separable and the other one is a general measurable space whose points parameterize a family of Borel probability measures on the first space such that the sections of the given set 𝑆 in the product have positive measures.

The occurrence of problems regarding operating procedures that are not suitable for heavy equipment in the field is one of the causes of component life which is not maximally achieved. Therefore it is necessary to have an innovation to make it easier to monitor and operate heavy equipment, especially when there is a shift in work shift for heavy equipment operators. Operator experience in several mining activities, many operators shut down the engine suddenly so that the impact on the engine can cause over heating which results in excessive wear and will have an impact on engine performance. And therefore the purpose of design a microcontroller-based cooling down safety device is a tool that functions to turn off the engine when the engine is low idle with time settings according to the standard operating procedure of each machine. For machines that have been operated under load, the engine must be low idle / cooling down for a while, so that the heat on the engine surface is cool enough, so that hot components can be properly lubricated. By design a cooling down engine safety device, it is hoped that it can assist in the monitoring and operation of heavy equipment. From the results of field testing, the relay that controls the unit's electricity functions properly and the cooling down safety device has a precise timing.

Introducción. La enfermedad de Chagas es una de las principales parasitosis a nivel mundial, aunque se distribuye principalmente en zonas pobres de América Latina. Ante la falta de una vacuna efectiva o profilaxis, la búsqueda activa de personas infectadas y la prevención de la enfermedad son las mejores estrategias para combatirla. El objetivo de este estudio fue analizar la prevalencia de la infección por Trypanosoma cruzi y el conocimiento sobre la enfermedad de Chagas en comunidades del estado de Chiapas, México. Material y Métodos. Se realizó la prueba de ELISA a habitantes de dos comunidades que tenían reportes de la presencia de triatominos. A través de encuestas semiestructuradas se determinó el conocimiento sobre la enfermedad y datos de factores de riesgo. Resultados. Se analizaron 317 muestras, de las cuales seis resultaron reactivas a la infección por T. cruzi (1,89 %). Menos de la mitad (39) de los encuestados mencionaron conocer al insecto triatomino, pero de ellos la gran mayoría sabe que puede transmitir una enfermedad potencialmente mortal. Comúnmente conocen a los triatominos como chinches o talaje. Conclusiones. La enfermedad de Chagas sigue activa en zonas endémicas del estado de Chiapas.

Setiap manusia terlahir dengan memiliki kemampuan yang berbeda tergantung pemberian perlakuan atau stimulus. Hal inilah yang menyebabkan manusia harus mengenal apa yang dimaksud sebagai intuisi. Dengan intuisi memberikan peran pengetahuan dalam memutuskan dan bertindak lebih efektif.. Manusia dapat memperoleh pengetahuan melalui intuisi. Intuisi bukanlah suatu metode namun intuisi merupakan sebuah jenis kognisi. Terdapat tiga macam kognisi yaitu formal, algoritmik dan intuitif. Pemahaman konsep matematika dapat berlangsung sebagai interaksi antara kognisi formal, kognisi algoritmik, dan kognisi intuitif. Intuisi diakui oleh matematikawan banyak terlibat dalam kegiatan bermatematika. Walaupun pada kenyataan masih saja kontroversial, Situasi yang paling menguntungkan dalam pembelajaran matematika adalah dimana intuisi siswa dengan konsep matematika secara formal sejalan, tetapi akan menjadi masalah jika sering kali terjadi dalam pengajaran matematika adalah penerimaan siswa secara intuitif bertentangan dengan konsep matematika secara formal dan mengakibatkan terjadinya konflik kognitif bahkan bias kognitif yang dapat merintangi siswa untuk mempelajari matematika

MSME can encourage economic growth, social stability, and the development of the business world in Indonesia. Hence, the government attempts to increase MSME competitiveness to become a sustainable business on a larger scale. To realize this, MSME requires additional capital through bank loans. The purpose of this study is to determine the implementation of accounting at MSME in three provinces that have the most MSMEs, i.e., West Java, Central Java, and East Java. Moreover, this study also purposes at revealing the effect of accounting implementation on credit to financial institutions. This study involved seventy-five MSME respondents. The results of the study indicated that the implementation of accounting at MSMEs in the Provinces of West Java, Central Java, and East Java had been well implemented. However, the provision of credit by financial institutions was still considered sufficient since lending by financial institutions was not in accordance with the loan application proposed by MSMEs.

In Bangladesh, the transformation of dairy farming from livelihood-oriented to enterprise-driven farming system might require deeper understanding on the regional differences in terms of regional potential for further dairy development. This, however, entails detailed data on dairy farm at regional level. Since the data are relatively very scarce in one hand and on the other hand, even available, are contradicting among various sources in terms of data accuracy and precision, the application of the regional modeling on the data and extrapolates to the national data and vice-versa is one of the ways to identify the possible options to improve the data availability and quality. Considering this, the current study was undertaken to assess the data inconsistency by comparing the dairy herd structure and its milk production at regional level and propose a validation tool to arrive at the national data by using the regional findings. The International Farm Comparison Network (IFCN) Regional Modeling Approach (RMA) along with the locally developed Integrated Dairy Research Network (IDRN) farm model was used. The primary data was collected from three divisions (9 districts) from the North-Western part of the country. The results revealed that proportion of household farm dominates over family and business farm while considering the total dairy cow as unit for defining the farm type. The share of the cross bred cows to the local cows is 74.6% and 24.4%, respectively. However, the proportion of lactating cows over dry cows and heifer seems to be higher in local cows (48.8%) than cross breed cows (34.2%). The average milk production for all regions is 4.49 lit/day/cow while that for cross breed is 6.23 lit and local 1.71 lit/day/cow. Using regional model and its coefficient on average milk production, herd composition, proportion of lactating cows on total milk production of DLS and IDRN revealed that IDRN new model estimates 36.5% lower milk than the DLS in 2019 and 33.5% lower in 2018. The IDRN version 1.0 and 2.0 model difference was found to 15.4% and 18.3% lower for 2018 and 2019, respectively. The model setup, calibration and validation are time-demanding and challenging tasks for these large set of data, given the scale intensive data requirements, and the need to ensure the reliability data from multiple regions. This study concludes that regional modeling is quite useful for validating the regional share of the milk production and national milk production. However, this study would recommend for using standardized for data collection, validation and thus conducting further study on the other regions and finally including all regions of the country.

The sediment of #3 Well of the Greater Ughelli Depobelt are represented by sand and shale intercalation. In this study, lithofacies analysis and X-ray diffraction technique were used to characterize the sediments from the well. The lithofacies analysis was based on the physical properties of the sediments encountered from the ditch cuttings.  Five lithofacies types of mainly sandstone, clayey sandstone, shaly sandstone, sandy shale and shale and 53 lithofacies zones were identified from 15 ft to 11295 ft. The result of the X-ray diffraction analysis identified that the following clay minerals – kaolinite, illite/muscovite, sepiolite, chlorite, calcite, dolomite; with kaolinite in greater percentage. The non-clay minerals include quartz, pyrite, anatase, gypsum, plagioclase, microcline, jarosite, barite and fluorite; with quartz having the highest percentage. Therefore, due to the high percentage of kaolinite in #3 well, the pore filing kaolinite may have more effect on the reservoir quality than illite/muscovite, chlorite and sepiolite. By considering the physical properties, homogenous and heterogeneous nature of the #3 Well, it would be concluded that #3 Well has some prospect for petroleum and gas exploration.
Effect of Temperature and Concentration on the Physical Properties of Cholesteryl Pelargonate Near Transition Temperatures

Published: May 2021

Thermodynamic and acoustical study of cholesteric liquid crystal (CLC) was carried out near phase transition temperatures using an ultrasonic interferometer. The study of ultrasonic waves and related thermo-acoustical parameters provides information in understanding the nature of molecular interactions associated with liquid crystals. A statistical mechanical approach is used to calculate the viscosity of samples. The characteristic textures and phase transition temperatures are obtained with Polarizing Microscopy (POM). Fabry Perot scattering studies (FPSS) are used to ascertain the phase transition temperatures of CLC. The thermo-acoustical parameters have been calculated using experimental data with well-known formulae. The acoustical parameters show variation with temperature as well as with concentration of CLC. Anomalous behavior of these parameters is noticed at the clearing temperature of CLC. The variation of the parameters is explained in terms of solute-solvent molecular interactions in the solution. The molecular behavior, structural changes, and intermolecular interactions between CLC and solvent are discussed in detail.
