Jesus has spiritual revolution but he is not a political revolutionist. He did not try to reform the ruler in his time. The revolution in the sense of Jesus was to lift up the God values in this time. It is called as the social revolution. The revolution means the social repentance in the context of social relation. Jesus as the man of weak Jewish society in the time hoped to get the freedom of the Rome tyranny. Jesus was chosen as the social and spiritual revolutionist as the mission from God as the mission that was love Allah in the deepest heart and soul, love the people and the selves.

O cajá-manga (Spondias dulcis) é um fruto com elevado valor nutricional e compostos antioxidantes, estes agem na prevenção do estresse oxidativo causados por radicais livres e na redução dos riscos de doenças crônicas não transmissíveis. A determinação de compostos antioxidantes é difícil, pois diversos fatores interferem na eficiência de sua extração, levando a perda de compostos ativos. O objetivo do presente estudo consistiu na otimização do método de extração de compostos antioxidantes utilizando metodologia de superfície de resposta. As amostras foram submetidas a testes em que variam a relação: amostra: concentração do solvente, intervalo de extração, tempo de rotação e velocidade de rotação. Não houve diferenças significativa nos resultados em relação ao tempo de rotação, velocidade de rotação e a interação desses com as demais variações para a determinação da atividade antioxidante; no entanto, as diferentes concentrações do solvente e intervalo de extração, e a interação concentração do solvente x intervalo de extração foi significativo e afetaram a atividade antioxidante.

Published: August 2019

Estruturas de concreto armado estão sujeitas a inúmeras manifestações patológicas, sendo a corrosão iniciada pela difusão de íons cloreto uma das mais agressivas e onerosas. Por isso mesmo, diversos estudos têm sido conduzidos para determinar a vida útil dessas estruturas, mas ainda não há pleno consenso. Nesse sentido, este trabalho objetiva estabelecer um padrão de ensaio para determinar a vida útil de estruturas de concreto armado devido a ação dos íons cloreto, além de analisar a variação do coeficiente de difusão ao se utilizar distintas relações água/cimento. Para alcançar tais objetivos, foram adotadas normativas nacionais e internacionais para orientar as etapas de caracterização dos materiais, além da utilização de equações de modelagens de perfis de penetração de cloretos para determinar o coeficiente de difusão e, por consequência, a vida útil da estrutura. Por fim, pôde-se concluir que ao se diminuir a relação água/cimento, houve diminuição da concentração de cloretos em uma determinada camada, proporcionando assim maior vida útil para o concreto armado. Quanto à analise probabilística, foi possível notar que quanto menor a proporção de água e cimento maior o índice de confiabilidade, uma vez que a probabilidade de falhar também reduz.

Este artigo apresenta a análise da aplicação de um Recurso Educacional Aberto (REA), elaborado com o software Prezi, para a disciplina de História Antiga, do curso de História da Universidade Federal do Tocantins (UFT), Câmpus Araguaína. Com intuito de compreender as perspectivas dos acadêmicos e acadêmicas sobre a intersecção REA e educação foi realizada uma pesquisa qualitativa, orientada pelas narrativas apresentadas em um grupo focal e respostas obtidas em um questionário com questões fechadas e abertas. As respostas foram analisadas a partir da metodologia “análise de conteúdo”, que possibilitou a identificação de três categorias que permitiram avaliar as potencialidades e as fragilidades do REA, além de dialogar, de forma crítica, com a base teórica que subsidiou referencialmente esta pesquisa. Os resultados apontaram que, apesar de as dificuldades a superar, os REA representam uma resposta às novas demandas sociais que exigem a revisão de práticas pedagógicas e adequação do currículo à realidade educacional na atualidade.

Published: August 2019

A preservação da qualidade dos recursos hídricos é uma necessidade universal, exigindo maior atenção quando se trata de uma área de preservação ambiental como a Unidade de Conservação-UC do Monumento Natural das Árvores Fossilizadas do Tocantins-MNAFTO. Assim, o presente trabalho objetiva determinar a qualidade microbiológica do Ribeirão Bananeira, localizado dentro da UC no Município de Filadélfia. Para a análise microbiológica foi utilizada a técnica de tubos múltiplos na determinação de Coliformes fecais e totais, assim como a identificação da presença de Escherichia coli. Paralelamente, foram realizadas contagens de bactérias heterotróficas. Nos resultados observamos que todas as amostras estão fora dos padrões para consumo, caso esta seja utilizada como fonte pelos moradores das imediações, ou como água para recreação. A presença de E. coli na amostra 1 e de Coliformes em número elevado em todas as amostras, indicam a contaminação por animais ou pelo homem e outras fontes orgânicas, sugerindo como fonte o gado observado nas imediações. Concluímos que o conhecimento das características de base do Ribeirão Bananeira pode servir como estudo piloto para verificar a qualidade desse ambiente aquático em toda a área do MNAFTO, futuramente estes dados poderiam auxiliar nas estratégias de preservação desta Unidade de Conservação.

Published: August 2019

Abstract
Background

The effect of extremely low frequency electric field on cancer cell proliferation is studied in-vitro.

Methods

Prostate cancer cell culture type Du-145 has been grown in the form of spheroids. It is shown that ELF with 50Hz frequency is effectively suppressing the growth of spheroids and finally reduces their size.

Results

It is observed that low voltage low frequency electric filed applied for at least 2 hours a day over one week can stop the growth or even reduce the volume of multi-cellular tumor spheroids significantly. No effect for the case of electric field presence in order of 10 -30 minutes per day has been observed.

Authors: Moll-Khosrawi Parisa , Zimmermann Stefan , Zöllner Christian , Schulte-Uentrop Leonie 
Published: August 2019

Abstract
Background: Job satisfaction remains a manifold goal in all fields of the working world, as well as in anaesthesiology. Since Self-determination theory (SDT) has been introduced by Deci and Ryan a lot of studies have been coducted, answering the question how motivation influences job satisfaction. It has been shown that intrinsic motivation and autonomous regulation lead not only to job satisfaction, but to better job performance. However, the roles of extrinsic motivation and controlled regulation and their effects on affect, job performance and job satisfaction have not been worked out clearly. No investigation has been done so far, analysing motivation of anaesthesiologists. Method: A cross-sectional study design was chosen to assess situational motivation and job-satisfaction, within a sample of anaesthesiologists, applying the Situational Motivation Scale. Differences of motivational expression in residents of different training years, attendings and consultants were analysed, as well as the correlation of motivational quality with job-satisfaction. Results: The invested group showed the same pattern throughout the motivational continuum, with consultants reporting the highest levels of intrinsic (6.02, 0.44), identified (5.78, 0.71) and introjected (4.69, 0.80) regulation. The consultants showed the highest computed controlled (3.29, 0.64) and autonomous motivation index (5.90, 0.55). The lowest intrinsic motivation was found in the group of attendings (5.70, 0.92). Job satifaction was correlated with intrinsic motivation (0.0360, p<0.01) and negatively correlated with amotivation (-0.265, p<0.05). Conclusion: Intrinsic motivation and autonomous regulation are necessary for achieving job satisfaction, the presence of controlled regulation and extrinsic behavioural regulation have no declining effects on job satisfaction but their expression might rather be even required for it. The Situational Motivation Scale proved its applicabilty to assess health care providers´motivational qualities and therefore can be considered for staff-talks and used as indirect predicotors of healt care providers´well-being and job-satisfaction.

Published: August 2019

Abstract
Background Oral health is acknowledged as an integral component of general health and plays an essential role in establishing a desired level of quality of life. Individuals with disabilities are at a higher risk for oral diseases due to underlying congenital anomalies and inability to receive the needed care to maintain oral health . Regular dental care is essential to maintaining optimal oral health. However, to date, there are no studies conducted in Jordan addressing the dental challenges and barriers to oral care faced by individuals with autism. The objectives of this study were to examine the use of dental services for individuals with autism and identify barriers that affect their access to dental care in comparison with healthy individuals in Jordan.Methods A case-control study was conducted. Participants included 296 Caregivers of individuals with autism and healthy developing individuals who completed a self-designed questionnaire that assessed access and barriers to dental services.Results The majority of the participants in the current study in both the control and the ASD groups have visited the dentist within the last year prior to completing the present survey. The main reason for visiting dental services was toothache (43%) while the least was routine checkup (11.6%) with significant difference ( P <0.05) between the groups. Barriers like; embarrassment (43.5%), lack of specialized dental staff (28.6%), lack of knowledge of how to treat disabled dental patients (26.6%), and inadequate facilities (34%) were significantly (P<0.05) higher among patients with ASD than the control.Conclusion Knowing and understanding the barriers for accessing dental care might improve overall health for individuals with autism. Furthermore, recognizing the challenges to accessing dental care for this population might help the oral health professionals to minimize these difficulties.

Abstract
Background: Asymptomatic carriage of Methicillin-Resistant Staphylococcus aureus (MRSA) can predispose the host to a wide array of infections that would pose a challenge in the management of the cases in a current era encompassed with antibiotic resistance. To inform public health strategies, the study sought to describe MRSA nasal carriage frequencies and the associated factors concerning nasal carriage among patients attending Mbale Regional Referral Hospital (MRRH). Methods: Two hundred eighteen consented participants presenting to the hospital for medical care between January and April 2018 were recruited to participate in this study. Sampling was done on both anterior nares using a pre-moistened swab and then transported to the laboratory at Room temperature for the detection of MRSA. Culture was performed on blood agar and plates incubated at 37℃ for 24 hours. Identification of Staphylococcus aureus was done using conventional biochemical tests . MRSA was detected phenotypically using cefoxitin (30µg) as a surrogate test as per the Clinical Laboratory Standard Institute guidelines 2017 version. Patient demographic characteristics and the MRSA nasal carriage factors were collected using a pre-tested questionnaire. The collected raw data was entered into excel and later imported into STATA software for analysis. Results: Overall, Majority of the participants were in-patients (138, 63.3%) with the proportions of both females and males among the participants being 154/218 (70.6%) and 64/218 (29.3%) respectively. Mean age for both female and male participants was 40.16 (SD± 17.04) years respectively. Staphylococcus aureus nasal carriage rate among the participants was 22.9% (50/218), with 72% (36/50) of the harboured strains phenotypically expressing methicillin resistance. Colonization with Methicillin Resistant Staphylococcus aureus did not show any significant relationship with all the studied factors. Conclusion: There was a moderate Staphylococcus aureus nasal carriage among the participants in Mbale Regional Referral Hospital. We also observed a highly displayed phenotypic expression of methicillin resistance among the isolated Staphylococcus aureus strains. The studied factors indicated an independent influence on the rate of nasal carriage. For surveillance purposes to combat future outbreaks, there is a need to do a larger study with better power to better draw generalizable conclusions of carriage in the population.
Evaluation of permeable sorption barriers for removal of Cd(II) and Zn(II) ions from contaminated groundwater
Authors: Zawierucha Iwona , Nowik-Zajac Anna 
Published: August 2019

Abstract
In the present study, continuous-flow column experiments (using glass column, Tygon tubing, and peristaltic pump Manostat Carter) were conducted to investigate the performance of permeable sorption barriers for the removal of cadmium and zinc from synthetic groundwater. Zeolite, ion-exchange resin and granular activated carbon as reactive materials were used. The effectiveness and stability of reactive materials were studied by monitoring of changes of metal ions concentration and selected background anions and cations concentration in groundwater during its flow through columns. Results showed that ion exchange resin was the most effective material of permeable reactive barrier (PRB). Performance of resin barrier remained effective (&gt;99.5% metal ions removal) for the time corresponding to on average of about 10,000 min. The high efficiency of ion-exchange resin in PRB for removal of heavy metals from groundwater was coupled with its reactivity and long barrier lifetime. The breakthroughs in the column tests on activated carbon and zeolite using synthetic groundwater occurred much earlier as compared to resin. Therefore, the system using resin requires smaller amount to treat a given volume of groundwater as compared to other materials. Moreover, the presence of other ions did not impact on activity and permeability of barrier filled with resin.
UV treatment and air quality in a pool facility
Authors: Nitter Therese Bergh , Svendsen Kristin v Hirsch 
Published: August 2019

Abstract
We investigated how UV treatment of indoor pool water affects the concentration of trihalomethanes (THMs) and chloramines (NCl3) in the air above one therapy pool. One-hundred and sixty-two samples of tTHMs (sum of the four most common THMs in swimming facilities) and thirty-six samples of NCl3 were collected simultaneously at poolside and in the extract channel in a room with one therapy pool for 2 days a week over a period of 5 weeks. When the UV lamp was on, the concentration of combined chlorine in the water decreased 58%, the concentration of tTHMs in the air increased 37%, and the concentration of NCl3 in the air decreased 15%. Between 42% and 56% of the gases in the air are recirculated back into the poolroom along with the recycled air. The correlation between NCl3 and THMs in the air was stronger when the UV treatment was on (r2 = 0.963) compared to when the UV treatment was off (r2 = 0.472). Using a linear mixed model, 30% of the variability in THMs was attributed to UV treatment. For NCl3, the number of bathers was the most important predictor variable. UV treatment has a limited effect on airborne NCl3 but increases the air concentration of tTHMs.
