Determination of the current-voltage characteristics of the photovoltaic cells using the CoachLabII+ measuring console
Authors: Różański Andrzej 
Published: February 2023

The Coach6 software and the CoachLabII+ measuring console coupled with a computer and equipped with appropriate voltage and current sensors were used to determine the current-voltage and power-voltage characteristics of the photovoltaic cells. The current-voltage and power-voltage characteristics for a single cell and cells connected in series and in parallel were tested depending on the light intensity. Using a simplified theoretical model of a photovoltaic cell based on the one-diode equivalent circuit and Shockley diode equation, the ideality factor, diode saturation current and source current were determined, fitting the appropriate theoretical relationship to the measurement results. Based on the current-voltage and power-voltage characteristics, the short-circuit current, open circuit voltage, maximum power, fill factor, conversion efficiency and load resistance were determined. The dependence of the determined parameters on the light intensity was discussed.

Settlement of the Hadhanah Dispute After Divorce of a Husband and Wife of Different Ethnicities in Indonesia (Case Study of Rao Pasaman)
Authors: Halim Syaflin Halim , Muhammad Abdurrazaq  
Published: February 2023

Post-divorce child care disputes between husband and wife of different ethnicities, namely Minangkabau and Tapanuli. The purpose of this discussion is to find the factors causing the emergence of differences in child custody rights and an analysis of Islamic law on the hadhanah dispute that occurred between the two ethnic Minangkabau and Tapanuli in Rao Pasaman. This research is a type of qualitative research using an ethnographic approach, where the author conducts interviews, observations and documentation studies on aspects or targets of the research subject. It turns out that in the author's findings in resolving the hadhanah dispute after a different ethnic divorce occurred in Rao Pasaman, it was the Minangkabau ethnic who wanted to resolve the dispute through the courts, while the Tapanuli ethnic only settled up to the non-litigation stage, namely through the village head (ninik mamak and hatobangon) without being resolved through a legal route. litigation (Religious Court). From the perspective of Islamic law, the settlement of the hadhanah dispute in Rao Pasaman does not use Islamic guidance. This is because in Rao Pasaman the majority of the people are Tapanuli while the Minangkabau people have become a minority.

Published: February 2023

Conservation of the historical and cultural environmental values that humanity has created in certain natural environments within the millennia of civilization, as in Italy. Both historical and cultural environmental values are not just the material values of societies, it is vital that has rich references in the creation of society structures. The aim of this work is to review the principles and theories of protection from past to present in Italy, which is one of the strong and rooted countries in the protection of the historical and cultural environment. Conservation of historical environment and structure development of new building applications in historical environment applications were made, and legal legislation in Italy to the present will be examined. In this context, firstly, information about the physical, geographical and historical development of Italy will be reviewed, then important historical structures of Italy will be discussed. Finally, information about the history of Italy, the principles and theories based on centuries will be evaluated with the years of its emergence. As results, these theories and principles have been applied in long periods due to socio - economic deficiencies. Among the most common problems in protection in Italy are the inadequacy of protection consciousness, conflict and contradictions of authority.

Published: February 2023

A pesquisa busca técnicas alternativas para expansão da vida de prateleira dos alimentos, isto tem impulsionado estudos sobre a utilização de conservantes naturais, tais como as bacteriocinas e óleos essenciais, que são considerados agentes antimicrobianos naturais. No entanto estes antimicrobianos naturais, não são adicionados diretamente em produtos alimentícios, devido a alterações sensoriais e em suas características físico e química. Com avanço tecnológico da microencapsulação, tem sido um potencial em fornecer sistemas que garantem estabilidade para os antimicrobianos naturais desta forma podendo compor a matriz de alimentos. Portanto, o objetivo desse trabalho foi microencapsular a enterocina produzida por Enterococcus durans MF5 e óleo de orégano usando leitelho. Para a microencapsulação, foram realizados três tratamentos: T1 controle leitelho, T2 leitelho/enterocina (LE), e T3 leitelho/enterocina/óleo (LEO). O material foi submetido ao processo de spray dryer e foram realizados ensaios para determinar a atividade antimicrobiana do material encapsulado contra as bactérias Listeria monocytogenes, Listeria innocua e Listeria ivanovi. O rendimento da microencapsulação foi de 13,01% e 11,63% para LE e LEO, respectivamente. Os resultados apresentados nos microencapsulados LE e LEO mostraram inibição contra todas as bactérias teste, foi constatado que a microencapsulação de enterocina e óleo de orégano mantiveram seu poder antimicrobiano. A efetividade da microencapsulação foi realizada por (FTIR), onde picos de intensidade entre as amostras na região 1000 a 930 cm-¹ e 1800 a 1500 cm-¹ foram observadas. Os resultados apontam para mudança no perfil químico das amostras encapsuladas, corroborando com a hipótese que o leitelho apresentou papel encapsulante da bactericiona e óleo de orégano.Portanto a microencapsulação aumenta a eficácia antimicrobiana dos antimicrobianos.

Published: February 2023

Introdução: A transgeneridade é um fenômeno que pode ocasionar sofrimento psíquico naqueles que o vivenciam, configurando o que se chama de “disforia de gênero”. Apesar dos avanços, sabe-se que esse grupo é mais vulnerável ao adoecimento mental - principalmente caso não haja uma terapia de afirmação de gênero adequada. Objetivo: Expor quadro de disforia de gênero severa agravado pela falta de intervenção multidisciplinar apropriada. Descrição do caso: Menina transgênero, 13 anos, iniciou quadro de humor deprimido, automutilação, ideação suicida, descuido com higiene, mutismo e retraimento social desencadeado pela não aceitação dos seus caracteres sexuais. O mutismo estava relacionado ao descontentamento com sua voz, de tonalidade grave. Não realizava comunicação verbal em casa ou nas consultas que, mesmo presenciais, eram feitas por cartas. Uma demanda era o bloqueio hormonal da puberdade, mas os especialistas da cidade não se sentiam seguros para conduzir o caso. Hoje, após se mudar para um grande centro com a família, realiza terapia multidisciplinar e tratamento farmacológico, sendo acompanhada por psiquiatra, endocrinologista e fonoaudióloga, com melhora do quadro de adoecimento mental. Conclusão: O relato reafirma a necessidade da equipe multidisciplinar capacitada para abordagem e manejo da disforia de gênero e demais patologias que acometam indivíduos transgêneros. Observa-se a falta de acesso ao serviço em diversas áreas, sendo necessário, portanto, proporcionar um cuidado acessível para garantia da saúde desta população.

Published: February 2023

Chemical phenomena involving three phases (solid, liquid, and gas) are often found in the industry. Carbonate (CaCO3) is widely used in industries as a powder-making material in the cosmetic industry, a pigment in the paint industry, and filler in the paper and rubber industry. This research aim to study the ordering process carbonate deposits (CaCO3) from the absorption process of CO2 gas with Ca(OH)2 suspension. The absorption reaction of CO2 gas with Ca(OH)2 suspension was carried out in a stirred slurry tank reactor. Initially, the reactor containing water was heated to a certain temperature, then Ca(OH)2 was added to the reactor. Furthermore, CO2 gas with a certain flow rate and temperature (according to the reactor temperature) is flown with the help of a gas distributor. Samples were taken every 1 min until the concentration of Ca(OH)2 could not be detected (completely reacted). The variables in this study were: stirrer rotation speed (5.66711.067 rps), CO2 gas flow rate (34.0127–60.5503 c/s), and temperature (30–50°C). The mass transfer coefficient and the reaction rate coefficient were determined by minimizing Sum of Squares of Errors (SSE). This experimental process follows a dynamic regime. A dimensionless number relationship for the gas-liquid mass transfer for the value range is Re1 = 18928.76-38217.20, Sh = 0.07928 Reg0.4383 Rel0.4399 Sc0.6415 with an error of 5.19%. The dimensionless number relationship for solid-liquid mass transfer is Sh = 0.0001179 Reg0.4674 Rel0.5403 Sc1.444 with an error of 7.31%. The relationship between the reaction rate constant and the temperature in the 30-50 °C range can be approximated by the Arrhenius equation, namely kr = 1771000 e-2321.4/T cm3/mgmol/s with an error of 3.63%.

Published: February 2023

Field and experimental data on aquatic ecosystem species show the effect of fear on changing prey demographics. The fear effect has an impact on aquatic ecosystems, such as species migration to settled areas. In this paper, the type of research described is a literature study. The cost effect assigned to the reproductive system of the prey population and the predation function response are given as Holling Type IV for research purposes to model the fear effect. Some research novelties, the equilibrium points are all shown in the population dynamics system model with an analysis of positive equilibrium. Positive and biologically realistic equilibrium points were analyzed using the Routh-Hurwitz criterion which is mathematically a local asymptotically stable. A pair of imaginary eigenvalues with a negative real part can increase population growth. An equilibrium region showing equilibrium for several parameters such as extinction, no predators, and two populations coexisting in a sustainable manner. The correlation and fluctuation of fear and fear cost were investigated to obtain a better model. The results of the numerical simulations show that the prey population becomes more daring to fight or fighting power with significant prey growth rates or high predator mortality rates.

Fusion Landsat-8 Thermal TIRS and OLI Datasets for Superior Monitoring and Change Detection using Remote Sensing
Authors: Dibs Hayder , Ali Alaa Hussein , Al-Ansari Nadhir , Abed Salwan Ali 
Published: February 2023

Currently, updating the change detection (CD) of land use/land cover (LU/LC) geospatial information with high accuracy outcomes is important and very confusing with the different classification methods, datasets, satellite images, and ancillary dataset types available. However, using just the low spatial resolution visible bands of the remotely sensed images will not provide good information with high accuracy. Remotely sensed thermal data contains very valuable information to monitor and investigate the CD of the LU/LC. So, it needs to involve the thermal datasets for better outcomes. Fusion plays a big role to map the CD. Therefore, this study aims to find out a refining method for estimating the accurate CD method of the LU/LC patterns by investigating the integration of the effectiveness of the thermal satellite data with visible datasets by (a) adopting a noise removal model, (b) satellite images resampling, (c) image fusion, combining and integrating between the visible and thermal images using the Grim Schmidt spectral (GS) method, (d) applying image classification using Mahalanobis distances (MH), Maximum likelihood (ML) and artificial neural network (ANN) classifiers on datasets captured from the Landsat-8 TIRS and OLI satellite system, these images were captured from operational land imager (OLI) and the thermal infrared (TIRS) sensors of 2015 and 2020 to generate about of twelve LC maps. (e) The comparison was made among all the twelve classifiers' results. The results reveal that adopting the ANN technique on the integrated images of the combined TIRS and OLI datasets has the highest accuracy compared to the rest of the applied image classification approaches. The obtained overall accuracy was 96.31% and 98.40%, and the kappa coefficients were (0.94) and (0.97) for the years 2015 and 2020, respectively. However, the ML classifier obtains better results compared to the MH approach. The image fusion and integration of the thermal images improve the accuracy results by 5%–6% from the proposed method better than using low spatial-resolution visible datasets alone.
