Published: April 2022

In this study, TiO2 doped with Cu has been successfully synthesized using the sol-gel method by varying the addition of Cu and the calcination temperature. Sample preparation was started by mixing 0.75 mL of 37% HCl in 49.25 mL of 96% ethanol and stirred with a magnetic stirrer for 10 minutes. Then 10 mL of TTIP (Titanium Tetraisopropoxide) was added dropwise using a dropper and the solution was stirred again with a magnetic stirrer for 60 minutes. Then added Cu with variations of 1%, 2%, 3%, 4%, and 5% and stirred again for 60 minutes using a magnetic stirrer. The sol solution was then put into the furnace at a temperature of 100°C for 3 days. The crystalline sol solution was then mashed with a mortar to a submicron size, then washed with 50 mL of Aquades and stirred using a magnetic stirrer for 10 minutes. The washed samples were then dried in a furnace at a temperature of 100°C for 1 day. Followed by calcination for 3 hours with temperature variations of 450°C, 500°C, 550°C and 600°C to release the gases in the nanoparticles. Cu-doped TiO2 nanoparticles were characterized using test equipment such as XRD, SEM-EDX, and UV-Vis. From the results of XRD analysis obtained 3 phases namely Brookite, Rutile and Anastase, and the crystal size is unstable and the shape of the sample particles is tetragonal. The results of the SEM-EDX analysis showed that the content of the sample was in accordance with the experiments that had been carried out. The results of UV-Vis analysis show that the wavelength is inversely proportional to the bandgap energy.

Abstract

Islamic sciences are sometimes separated from the sociological, historical, and philosophical context in which the Islamic sciences are compiled and developed. In addition, the emergence of Islamic studies in Europe and the West since the 1960s has a contemporary style and character and is different from the classical and medieval Islamic sciences. Likewise, the birth of the era of globalization, the millennium, and the industrial revolution 4.0 which was marked by the use of smart technology (intelligent technology) and artificial intelligence (artificial intelligence) that can take over human work, and are used in all aspects of life. By using library sources, observations, and analysis results on the dynamics that occur in the study of Islamic sciences, such as contemporary Islamic studies that use multi approaches (various approaches), the integration of knowledge, as well as community needs for religion individually and socially, this paper offers a new arrangement of Islamic sciences by first stating the background, approach, methodology, principles, and systems of Islamic sciences, and their impact on life.

Abstrak

Ilmu-ilmu keislaman terkadang lepas dari konteks sosiologis, historis, dan filosofis di mana ilmu-ilmu keislaman tersebut disusun dan dikembangkan. Selain itu munculnya Studi Islam di Eropa dan Barat sejak tahun 1960-an yang memiliki corak dan karakter kontemporer dan berbeda dengan corak ilmu-ilmu keislaman abad klasik dan pertengahan. Demikian pula lahirnya era globalisasi, millennium dan revolusi industri 4. 0 yang ditandai oleh penggunaan smart technology (teknologi cerdas) dan artificial intelligence (kecerdasan buatan) yang dapat mengambil alih pekerjaan manusia, dan digunakan dalam seluruh aspek kehidupan. Dengan menggunakan sumber kepustakaan, hasil pengamatan, dan hasil analisis terhadap dinamika yang terjadi dalam kajian ilmu-ilmu keislaman, seperti kajian Islam kontemporer yang menggunakan multi approaches (ragam pendekatan), integrasi ilmu, serta kebutuhan masyarakat terhadap agama secara individual dan sosial, tulisan ini menawarkan sebuah susunan baru tentang ilmu-ilmu keislaman dengan terlebih dahulu mengemukakan latar belakang, pendekatan, metodologi, prinsip dan sistem ilmu-ilmu keislaman, serta dampaknya bagi kehidupan.
Ilmuan muslim polimatik di abad pertengahan
Authors: Subagiya Bahrum
Published: April 2022

The Middle Ages was a golden age for Islamic civilization and a dark age for the West. In that century, many Muslim scientists contributed greatly to the advancement of technology in this modern era. But my goodness, many Muslims know the history of the greatness of Islamic civilization and do not know the figures of Muslim scientists. This article aims to explore the factors that gave birth to the gold and to find the year of the big figures who influenced literature research. The results of this study found that the birth of polymathic Muslim scientists stemmed from the core teachings of Islam. Where Islam strongly encourages its people to deepen knowledge, not only religious knowledge but also other sciences that have benefits for human benefit. Among the great figures who have succeeded in contributing to modern civilization are Ibn Zakariya al-Razi Al-Kindi Ibn Sina, Nasir al-Din al-Tusi, Ibn Rushd, Al-Khwarizmi, and others.

The prohibition of seclusion is an early prevention of adultery because the act of adultery basically starts from the things that lead to it. The ratification of Qanun No. 14 of 2003 concerning Seclusion at the beginning of the application of Islamic law in Aceh as a qanun in the field of jina>ya>t was not without reason, the selection of the qanun had at least two reasons. The first reason, the act of seclusion is a form of immorality (haram) in Islamic law and is very disturbing to the community but has not been handled properly. Second, the existence of euphoria within the community in the form of 'people's justice' against the types regulated in this qanun jina>ya>t, in order to avoid taking vigilantes in the midst of society, the Aceh Government ratified Qanun No. 14 of 2003 as a form of anticipation to various disturbances in Acehnese society.

Objective: Evaluation of various bulk-fill composite materials with respect to the microhardness values of the top and base surfaces upon variation in the composite thickness. The effect of aging and comparison of the fluorescence properties exhibited by the materials at different thicknesses will also be examined. Materials and Methods: For all samples, calculations were carried out using a family F probability, with a repeated family design including interactions within and among the factors, which resulted in 135 sample units, with 27 samples per experimental group. Z350, AURA, TETRIC, SDR, and FBF composites were employed with thicknesses of 2, 3, and 4 mm, initially being submitted to microhardness measurements (n=9). Aging was carried out using an aqueous ethanol solution. After aging the microhardness values of the samples were measured again, and a comparative analysis was performed for the fluorescence of all samples. Results: Aging, sample thickness, and the type of material were found to affect both the surface microhardness and the fluorescence values. In addition, the AURA and SDR bulk-fill composites were the least susceptible to differences in thickness in terms of the top and base surface microhardness values. Conclusions: Although the manufacturers of some bulk-fill composites recommend the use of material increments of 4 mm, the results of this study suggest that further research is required before clinical application.

Deslocamento das posições obtidas via PPP – IBGE causado por alterações nos parâmetros de transformação entre IGb08 e SIRGAS2000
Authors: Statella Thiago , Gonçalves Patrícia Regina da Silva
Published: April 2022

Neste trabalho investigou-se o impacto que a alteração nos parâmetros de transformação entre IGb08 e SIRGAS2000 podem causar nas coordenadas processadas pelo serviço PPP-IBGE antes de 17/05/2020, data em que IBGE adotou a modificação. Os parâmetros aplicados até a referente data consideravam 3 translações, 1 fator de escala e 3 rotações entre os dois sistemas de referência geodésicos. Os parâmetros adotados posteriormente a 17/05/202, além de trazerem translações ligeiramente diferentes, consideram as rotações como nulas, isto é, adotam que os dois sistemas são paralelos. Para demonstração, foram adotadas posições processadas via PPP-IBGE em 2016, antes das mudanças nos parâmetros. Foram comparadas as coordenadas convertidas de IGb08 para SIRGAS2000 utilizando-se os dois conjuntos de parâmetros, e o deslocamento obtido foi de ~ 3 cm, dentro do esperado, segundo o IBGE. Portanto, para a maioria das atividades práticas, a depender da precisão exigida, as alterações podem ser negligenciadas.

O procedimento licitatório é fundamental para a Administração Pública e, por isso, vem passando por aprimoramentos nas últimas décadas. Devido a essa preocupação, em 2021 entrou em vigor o novo marco regulatório das aquisições e contratações públicas (Lei nº 14.133/2021) que busca reunir as qualificações basilares e essenciais para a instauração, execução do processo licitatório e a fiscalização dos contratos de forma mais eficiente. O presente artigo tem por objetivo descrever as formas consensuais de solução de conflitos previstas na nova lei de licitações (Lei nº 14.133/2021) e identificar os benefícios que estes métodos podem trazer para a Administração Pública na execução das aquisições e contratações. Para a produção deste estudo foi realizada uma pesquisa bibliográfica de abordagem qualitativa e natureza básica, mediante levantamento de dados indiretos, através de revisão bibliográfica.  Como resultado do presente estudo, foi possível observar que a aplicação das métodos consensuais de resolução de conflitos, ainda que do ponto de vista teorético, tem o potencial de propiciar a celeridade na resolução dos problemas, diminuição dos conflitos entre a Administração e os contratados e economicidade nos processos judiciais.

Ananas comosus var. erectifolius is a bromeliad native of the Amazon Complex has aroused great interest of the industries due to a softness, strength and low density of fibers extracted from its leaves. The frequent demand and effective protocols for in vitro regeneration and establishment of species, of commercial and environmental interest, encourages studies of organogenesis induced by growth regulators. The rhizogenesis or in vitro rooting is the last step of the regeneration process and is often considered the greatest challenge to be overcome. Rhizogenesis of Ananas comosus var. erectifolius was evaluated under the influence of the growth regulators naphthalene acetic acid (NAA) and indole butyric acid (IBA). Seven experiments were performed using different concentrations of growth regulators on solid MS medium under controlled environmental conditions. The results will improve the laboratorial protocols of induction, multiplication, elongation and production of root biomass for A. comosus var. erectifolius. The in vitro rooting was feasible and better results were observed using 1.0 mg L-1 NAA + 1.0 mg L-1 IBA.

O consumo de alimentos funcionais, principalmente aqueles que contêm ingredientes bioativos e baixas calorias, tem aumentado em sincronia com a maior preocupação com hábitos alimentares saudáveis. Neste estudo, um leite desnatado com adição do probiótico Bifidobacterium animalis subsp. Lactis HN019™ e edulcorante foi desenvolvido e caracterizado. A viabilidade do probiótico durante o armazenamento refrigerado (5 ° C/60 dias) e a resistência às condições gástricas e entéricas simuladas também foram avaliadas. O produto foi avaliado por provadores não treinados que realizaram testes de preferência e intenção de compra, comparando-o a um leite probiótico com açúcar e a um leite probiótico não adoçado. O produto pronto para consumo apresentou 0,38% de ácido lático, pH 5,34, teor de proteína 3,92%, carboidrato 4,08%, extrato seco total 8,81% e teor de cinzas 0,81%. O probiótico B. lactis HN019® multiplicou e permaneceu no produto em altas concentrações (9,04 log UFC / mL). Durante o armazenamento refrigerado, houve redução de apenas um ciclo logarítmico na viabilidade do probiótico. Foi observada uma redução sutil no valor do pH e aumento na acidez titulável (p <0,05). Durante a simulação das condições do trato gastrointestinal (TGI), a linhagem HN019 apresentou uma taxa de sobrevivência de 93,72% e 83% no leite probiótico recém-produzido e armazenado por 60 dias, respectivamente. Em relação à aceitação sensorial, os provadores demonstraram preferência pelo leite adoçado com açúcar, seguido pelo leite com edulcorante, enquanto o fermentado não adoçado teve menor preferência. Aplicando a escala de intenção de compra, os painelistas indicaram que talvez comprassem o produto com adoçante caso ele estivesse disponível no mercado. O produto foi definido como um leite desnatado probiótico light, uma vez que o valor calórico foi reduzido 53.04% se comparado a leites cultivado comerciais. Seu sabor suave, devido à baixa acidez, alta viabilidade e resistência do probiótico ao TG in vitro, e o baixo teor calórico, o diferenciam dos leites fermentados comerciais atualmente disponíveis. Portanto, esse produto com baixas calorias pode preencher um nicho de mercado pouco explorado por consumidores com restrições calóricas e que valorizam o consumo de alimentos funcionais como os probióticos.

A doença periodontal é um processo inflamatório crônico multifatorial, que leva à destruição das estruturas do periodonto e posteriormente perda dentária, prejudicando a saúde bucal e geral. A membrana amniótica (MA) atraí atenção como biomaterial para a medicina regenerativa; sua arquitetura única garante excelentes propriedades biológicas e mecânicas. O objetivo é analisar o potencial da MA na regeneração dos tecidos periodontais na periodontite induzida em ratos. A casuística envolveu 26 ratos machos Rattus norvegicus, Albinos, Wistar, com peso aproximado de 200 a 250g, os quais após o período de aclimatização foram divididos aleatoriamente nos grupos: Grupo normal (n=6): os animais não foram submetidos a nenhum procedimento, seguindo o percurso normal do experimento; Grupo ligadura (n=10): os animais foram submetidos à ligadura para indução da periodontite, e após 2 semanas esta foi removida e seguiram sem tratamento; Grupo ligadura + MA (n=10): os animais foram submetidos a ligadura para indução de periodontite, após 2 semanas a ligadura foi removida e a MA colocada ao redor do defeito ósseo. Após 4 semanas de atuação da MA os animais foram eutanasiados e as análises macroscópica, morfométrica, histológica, histomorfométrica e estatística foram realizadas para avaliar o reparo periodontal. Observou-se significativa instalação da doença periodontal, e após a colocação da MA, verificou-se a diminuição da perda óssea alveolar e da profundidade de sondagem, ganho no nível de inserção conjuntiva, e tecidos periodontais com aspecto de normalidade. Conclui-se que a MA estimula o reparo periodontal após ter removido o agente etiológico que estava provocando a periodontite.

A cebolinha verde é uma hortaliça folhosa bastante utilizada na gastronomia brasileira. Sendo cultivada em diversas faixas de temperatura e em regiões que apresentam índices térmicos elevados, podem afetar o crescimento e desenvolvimento, tornando imprescindível a utilização de ambientes protegidos. Objetivou-se avaliar o desempenho agronômico da cebolinha verde, nutrida com cartão de cupinzeiro, sob diferentes ambientes de luz.  O experimento foi desenvolvido em casa de vegetação pertencente a Universidade Federal do Recôncavo da Bahia, localizada na cidade de Cruz das Almas-BA. O delineamento experimental foi inteiramente casualizado, constituído por quatro ambientes de luz, formados por telados revestidos por malhas fotoconversora vermelha, preta e termorrefletora Aluminet, ambas com 50 % de irradiância, e um tratamento controle, ou seja, sem malha, empregando-se oito repetições por tratamento. Uma planta foi cultivada em vaso, contendo areia lavada e 75 g dm-3 de material de cartão de cupinzeiro. Decorridos 90 dias de aclimatização, foram avaliadas a altura da parte aérea; comprimento do sistema radicular; número de folhas; diâmetro do coleto; relação altura da parte aérea e comprimento do sistema radicular; massas da matéria seca da parte aérea, do sistema radicular, e total; relação entre as massas do sistema radicular e da parte aérea. Os dados foram submetidos à análise de variância e em função do nível de significância utilizou-se o teste de comparação múltipla de Tukey. Concluiu-se que as variáveis: altura, número de folhas e relação altura raiz em plantas de cebolinha foram significativamente superiores quando desenvolvidas sob telados constituídos com malhas vermelha e preta.

Amor Island (Alter do Chão, Santarém, Pará, Brazil) is considered a region of great natural beauty and a national and international tourist attraction. The aim of this study was to determine the composition and density of the phytoplankton of the Amor Island, with emphasis on heterocytous cyanobacteria. Water samples for phytoplankton were collected and analyzed at seven points in October 2021. Filaments of heterocytous cyanobacteria were cultured and analyzed, measuring the cells of the first 30 trichomes. The abundance, diversity and evenness of phytoplankton species were calculated and balneability of beach in relation to algal blooms was evaluated. 106 generic and infrageneric taxa were identified, highlighting the Chlorophyta. Phytoplankton density was higher at Verde Lake (145.6 ± 22.0 org.L-1), diversity and evenness were higher at point 03 (Lake Verde) with 3.0 bits.cell-1 and 0.47, respectively. The most abundant species were: Aphanothece minutissima, Ankistrodesmus sp., Aphanothece sp., Aphanizomenon sp., Mougeotia sp., Merismopedia sp. and Quadrigula sp. The average density of cyanobacteria was higher in the Tapajós River (517.0 cell.mL-1). No algal and cyanobacterial blooms were identified, indicating water appropriate for bathing. Through morphological and morphometric description, the cultivated species were identified as Aphanizomenon gracile and Cylindrospermopsis/Raphidiopsis raciborskii, cited among the cyanobacteria with the highest occurrence of toxic blooms in the world. The region deserves phytoplankton monitoring studies, due to reports of cyanobacterial blooms, and greater knowledge of its planktonic biodiversity, since it is a threatened region.
