Published: March 2023

The Covid-19 pandemic has caused students to experience learning loss or a slowdown in student learning development in literacy, numeracy, and science. Another pandemic's impact is changing students' behavior and emotions, such as difficulty concentrating during online learning, sensitivity, anxiety, and other excessive worries. In order to overcome learning problems, one strategy from the government is releasing Kurikulum Merdeka, which focuses on Project-based learning. Several studies discussed the difficulties of project learning from the teacher's view, but no data explicitly discusses students' difficulty in implementing project learning. This research aims to identify the challenges and obstacles experienced by students when carrying out project learning. Furthermore, this research is grounded research used as reflection material for teachers in planning and improving the quality of project-based learning. The Project Learning Experience questionnaire was distributed to seven high schools in Kota Bandung, and 592 responses were recorded. From the data findings, students faced challenges in collaborative activities; contributions, time management, problem-solving, teamwork, and investigation techniques due to a lack of self-regulation. Theoretical contributions and implications for educational practices are discussed

Authors: Akhsan Hamdi , Irfan Muhammad , Iskandar Iskhaq
Published: March 2023

The Indonesian region is affected by the monsoon system, which leads to a rainy season in December-March and a dry season in June-September. Global warming caused by human activities is increasing the risk of extreme climate events like floods, droughts, etc. The study aims to analyze the trends and correlations of extreme temperatures in the South Sumatra coastal area and its relationship with the DMI and Nino 3.4 indices. The four-stage research methodology includes data collection, extreme temperature index calculation, trend detection and correlation analysis with ENSO. Results indicate that the region has seen a rise in temperature, with hot day/night temperatures increasing by 0.26-0.29°C per decade and cold day/night temperatures by 2-3°C per 100-1000 years. A strong correlation was found between the DMI index and daily maximum/minimum temperatures, as well as between the Nino 3.4 index and the Diurnal Temperature Range (DTR). The study projects that nighttime temperatures will increase faster than daytime temperatures in the future, with a proportional correlation between the Nino 3.4 index and extreme temperatures

O diabetes mellitus é uma das endocrinopatias de maior ocorrência na rotina da clínica médica veterinária e que mais necessitam de um estreito vínculo clínico-tutor e tutor-paciente devido ao seu tratamento e manejo dificultoso. Em cães, essa patologia acomete de 2 a 4 vezes com mais frequência as fêmeas que os machos. Diversos autores afirmam que tal ocorrência deve-se principalmente ao efeito diabetogênico dos hormônios presentes em excesso durante o diestro e a prenhez que conferem ao animal, durante este período, uma resistência insulínica fisiológica. Ao ser associada a outros fatores genéticos e ambientais como obesidade, hipercortisolismo, neoplasias, doenças degenerativas, medicamentos, infecções e inflamações crônicas, podem desenvolver um quadro de diabetes mellitus gestacional (DMG), assim como é observado em humanos. A progesterona e o hormônio de crescimento (GH) liberados em grandes concentrações durante o período gestacional e o diestro, são considerados os principais fatores predisponentes da diabetes mellitus em cadelas. Esses hormônios, por terem efeitos contrarreguladores da insulina, são responsáveis por expor estes animais a uma glicotoxicidade devido a altos índices glicêmicos, provocando uma exaustão das células beta pancreáticas, responsáveis pela produção e liberação da insulina, caracterizando o diabetes mellitus gestacional. Tal condição merece um cuidado maior com manejo e tratamento insulínico afim de reduzir tanto a glicotoxicidade como os riscos no desenvolvimento de um quadro diabético permanente. O diabetes mellitus canino (DMC) traz transtornos imensuráveis à vida não só do paciente que será exposto aos riscos à saúde, mas também do tutor, pois requer cuidados intensivos e acompanhamento contínuo durante toda a vida do animal. Portanto, este trabalho teve o intuito de esclarecer a maior incidência desse acometimento em cadelas e explanar seus mecanismos envolvidos, para que assim possam ser estabelecidos protocolos médicos capazes de igualar o número de fêmeas acometidas ao de machos nessa espécie. Para isso, foi realizado pesquisas bibliográficas em livros, artigos científicos, trabalhos publicados em eventos e trabalhos de conclusão de curso, extraindo destes, as informações mais cabíveis ao tema abordado.
Empreendedorismo na Base da Pirâmide

Published: March 2023

Este livro é resultado da dissertação de mestrado defen- dida e aprovada na área de Administração na PUC Rio e inves- tigou o empreendedorismo de baixa renda e o aprendizado e adoção de tecnologias de gestão por parte de empreendedo- res na cidade do Rio de Janeiro.
O desenvolvimento das tecnologias da informação e da internet transformou o modus operandi das organizações, tan- to em níveis estratégicos quanto operacionais. Desta forma o campo de estudos da aceitação e uso de tecnologias se de- senvolveu e ganhou interesse da comunidade acadêmica, uma vez que seus achados contribuíram para a compreensão dos fatores que inibiem ou potencializam o uso de tecnologias no ambiente organizacional por parte dos indivíduos. Ao mesmo tempo, desde a última década, o fenômeno de empresas mul- tinacionais desenvolvendo estratégias para mercados da ba- se da pirâmide se intensificou. No entanto, a literatura apon- ta que ainda há desafios a serem vencidos pelas organizações para que estas iniciativas obtenham resultados mais efetivos em termos de escala. Grande parte destes desafios está rela- cionada com a integração das operações das empresas multi- nacionais com os parceiros empreendedores locais, oriundos dos territórios de base da pirâmide. Uma vez que tal integra- ção passa pelo uso de tecnologias adotadas pelas empresas multinacionais, a literatura demonstra que há limitações e di- ficuldades por parte dos empreendedores para utilizarem tais tecnologias. Desta forma este trabalho buscou investigar o uso de tecnologia da informação por empreendedores de baixa renda no contexto de projetos orientados à base da pirâmide por empresas multinacionais.

Trehalose and ascorbic acid improves the Cryopreservation of umbilical Cord Blood hematopoietic stem Cells (CD34+) with low Concentrations of Dimethylsulfoxide
Authors: Sabbah Majeed Arsheed
Published: March 2023

Cryopreservation of umbilical cord hematopoietic stem cells (HSCs) is essential step in stem cell transplantation. The Dimethylsulfoxide (DMSO) mostly used as a cryoprotective agent, associated with toxic effects to stem cells. In order to minimize the effects of DMSO, low concentrations of DMSO with additional cryoprotectants should used. In this study mononuclear cells (MNCs) isolated by ficoll from umbilical cord blood (UCB), which contain hematopoietic stem cells (CD34+), were used for cryopreservation. Cryopreservation of UCB-derived MNCs was done for period of one month by using uncontrolled-rate freezing technique at -196˚C in liquid nitrogen. Cryopreservation solution was used which consisted of minimum essential medium (MEM) and 20% fetal calf serum (FCS) supplemented with the cryoprotectant dimethylsulfoxide (DMSO) in two concentrations 2.5% and 5% DMSO, lower than usually used 10%, with and without 25µg/ml trehalose or 80µg/ml ascorbic acid to improve cryopreservation process. The addition of trehalose and ascorbic acid improved cryopreservation process in comparison with control. Addition of 5% DMSO alone and with additives showed a better result than 2.5% DMSO alone or with additives for cryopreserving CD34+ cells as indicated by immunocytochemistry. Washing out DMSO also affected the count and viability of MNCs. These results indicated that it could use low concentrations of DMSO in cryopreservation of HSCs by association with trehalose and ascorbic acid.

Authors: Abdel-Razzaq Faten Abdel-Wahhab , Dhaigham Ayad Abdul Razzak , Yaseen Sameer Khudhur
Published: March 2023

Iraq suffers from serious pollution with harmful particles that have important direct and indirect effects on human activities and human health. In this research, a system for detecting pollutants in the air was designed and manufactured using infrared laser technology. This system was used to detect the presence of pollutants in the dust storms that swept the city of Baghdad which could have a negative impact on human health and living organisms.
The designed detection system based on the use of infrared laser (IR) with a wavelength of 1064 nm was used for the purposes of detecting pollutants based on the scattering of the laser beam from these pollutants. The system was aligned to obtain the best signal for the scattered rays, which were detected using a digital storage oscilloscope.
These studies were conducted during the dust storms that occurred intensely in Baghdad in the months (April, May, June and July) of the year 2022. Where multiple samples were taken at different periods in these storms, measurements were also done during the storm. The types of polluting elements found in the dust of the storms are: carbon, bromine, chlorine, hydrocarbons alcohol, ether, hydroxyl group, carbon, C=C (aromatic ring), nitrogen dioxide (aromatic nitro), and carbon monoxide. The value ​​of dust pollutant concentrations is (125.67 mg. m-3).

Authors: Hussein Alyaa , Abdullah Hadder M.
Published: March 2023

The Indian costus plasma properties are investigated, including electron temperature (Te), electron density (ne), plasma frequency (fp), Debye sphere length λD, and amount of Debye (ND), using laser-induced breakdown spectroscopy (LIBS). The study is done for different laser energies ranging from 300 to 600 mJ. The Boltzmann plot is used to calculate the temperature. The Indian costus is spectroscopically examined in the air with the laser 10 cm away from the target and the optical fiber 0.5 cm away. The X-ray fluorescence (XRF) analysis reveals that the Indian costus contains various minerals, each with a different percentage, which explains why the optical emission spectrum has so many peaks. Optical emission spectroscopy (OES) is used to analyze the plasma spectrum of the Indian costus in the air. The results show that as the laser energy grows, the amount of Debye will be greater, i.e (ND) >>>1, at a laser energy of 300 mJ, ND is 2.506775, as it increases to 600 mJ, ND becomes 3.006884, the electron temperature Te for 300 mJ is 1.86209223 eV as the energy increases, the Te becomes 2.205687353 eV.
Evaluation of Resonance Strengths and Reaction Rates of 22Ne (p, gamma) 23Na Nuclear Reaction at Thermonuclear Energies
Authors: A.Selman Ahmed
Published: March 2023

At thermal energies near stellar conditions, nuclear reactions are sensitive to resonance strengths of the nuclear reaction cross-section. In this paper, the resonance strengths of  nuclear reaction were evaluated numerically by means of nuclear reaction rate calculations using a written Matlab code, at the energies of interest in stellar nuclear reactions. The results were compared with standard reaction before and after application of statistical analyses, to select the best parameters that made theoretical results as close as possible to the standard values. Fitting was made for different temperature ranges up to 10 GK, 0.6 GK and 0.25 GK. The evaluated results showed that as the temperature range becomes narrower, more error is added to the evaluated strengths. A proper strength value based on the most recent measured one suggested the difference of at least one order of magnitude can be solved using a numerical evaluation for energies less than 650 keV.

The learning model is one of the strategic approaches that must be carried out by the teacher systematically and procedurally in organizing learning activities to achieve optimal learning goals. In physics, the learning process is still centered on the teacher, where the teacher still conveys the overall concept on the blackboard which is not following the 2013 curriculum that has been set. This proves that teachers who have not applied the learning model according to the demands of the 2013 curriculum This research was conducted at SMAN 08 Muaro Jambi on grade X IPA 2 students which aimed to determine student responses when given a discovery learning model during the physics learning process. The instrument used was a student questionnaire with a sample of 21 students. This research uses a mixed-method with a sequential explanatory design. Data analysis techniques use descriptive statistics to get the average value, mode, median, minimum, maximum. Based on the results of the study found that the level of student response to the learning model is categorized as good with a percentage of 61.9%.

Quantitative reasoning has been highlighted as essential for middle-school student learning, particularly for themes that require students to make sense of relationships between quantities, according to a growing body of evidence. As a result, the current study adds to the body of literature that explores the growth of students' quantitative reasoning through teaching models. This study uses measuring tools such as a quantitative reasoning test and an observation sheet. The randomized pre-test–post-test control group design has been used in this investigation. The study included 95 second-year middle school students from Pangkep, Makassar, South Sulawesi, who were split into two groups: experimental and control. The N-gain index, which has high, medium, and low categories, was used to calculate the improvement of students' quantitative reasoning exam results. The finding of the data, 86.0 % of students in the experimental class increased their quantitative reasoning exam scores in the high category, while only 46.6% of students in the control class improved their quantitative reasoning exam scores. Students' quantitative reasoning improves substantially more when they utilize the problem-based learning models to learn about the linear program than when they use direct learning. As a result, students' quantitative reasoning can be improved by using problem-based learning models.

Mathematics is an instrument for solving problems in life. So, ability to solve mathematical problems is one of the most important skills. Practitioners of education do different approaches to develop the mathematical problemsolving ability of students. Efforts have been made such as an attractive learning model and providing external motivation. Most students, however, were unable to finish and prepare to solve mathematical problems in daily life. This is due to the belief that mathematics is not linked with life, anxiety in solving non-routine problems, and feelings of complacency that contribute to low motivation for students. The aim of this research is to gain an overview of the mathematical problemsolving skills of students in terms of students' mathematical dispositions. This research method is qualitative with a case study approach and this research was carried out on 35 grade XI students from a high school in the district of Indragiri Hulu. This research showed that students with high mathematical dispositions were able to apply indicators of problemsolving steps well, students with moderate mathematical dispositions were not able to properly apply indicators of mathematical problemsolving steps, and students with low mathematical dispositions found it difficult to understand the given mathematical problems. So, we concluded that students with good mathematical dispositions can well apply indicators of mathematical problemsolving steps
