Resumo Helicobacter pylori (HP) é um elemento vital na etiologia de úlceras pépticas e câncer gástrico. Esta pesquisa teve como objetivo determinar a frequência, distribuição e determinantes da infecção por HP em adultos e adolescentes com sintomas gástricos no distrito de Haripur, Khyber Pakhtunkhwa, Paquistão. Este estudo transversal foi realizado de junho de 2018 a junho de 2020 no Departamento de Tecnologia de Laboratórios Médicos da Universidade de Haripur, Paquistão. A presença de HP foi uma variável de pesquisa, enquanto sexo, faixas etárias, escolaridade, superlotação, hábitos alimentares, ingestão de leite, fonte de água potável e contato com animais foram variáveis de agrupamento. A técnica imunocromatográfica (TIC) foi utilizada para a detecção sorológica de anticorpos para HP. Todas as variáveis foram representadas por frequência e percentual com IC 95%. A prevalência de HP e sua distribuição por oito variáveis sociodemográficas foi comprovada pelo teste de ajuste do qui-quadrado, enquanto a associação foi verificada pelo teste de associação do qui-quadrado. Do total de 1.160 casos, 557 (48%) foram positivos para HP. A prevalência populacional foi maior em homens, na faixa etária de 20 a 40 anos, analfabetos, família ≤ 10 pessoas, consumindo comida de restaurante, usando tetra pack, usando água municipal e tendo contato com animais. A prevalência observada de HP foi semelhante à sua prevalência esperada na população. A distribuição observada de HP na amostra foi diferente de sua distribuição esperada na população por oito variáveis sociodemográficas. A presença de HP foi associada a todas as oito variáveis sociodemográficas além das faixas etárias.

Resumo As algas desempenham um papel significativo na redução dos gases de efeito estufa (GEE) emitidos pelos ruminantes, em particular o gás metano (CH4) gerado durante a fermentação ruminal do alimento. Euchaema cottonii é uma espécie de alga potencialmente cultivada em países tropicais. Um procedimento de conservação é necessário para uma aplicação futura no programa de redução de CH4. O estudo analisou como três métodos de secagem (secagem solar, secagem em forno e secagem por congelamento) afetaram a capacidade de E.cottonii em reduzir o metano CH4, medida por uma técnica in vitro. A adição de E. cottonii seco até 4% de matéria seca (MS) foi testada usando dietas de palha de arroz misturadas com concentrado na proporção de 70%:30% na base de MS. Foram realizadas medições da produção de gás, degradabilidade e o produto final da fermentação ruminal durante 48 horas de incubação usando um sistema de produção de gás e técnicas da ANKOM Daisy II. No geral, os três produtos secos de E. cottonii foram encontrados para reduzir consideravelmente a produção de CH4, aumentar a degradabilidade de MS e MO, bem como a produção total de VFA (P<0.05). Os três tratamentos não tiveram efeito na concentração de NH3 e na população bacteriana, mas diminuíram a população de protozoários (P<0.01). A redução da projeção de gás CH4 no rúmen foi afetada por todos os três métodos de secagem da mesma forma. Conclui-se que a adição de E.cottonii até 4% de MS é eficaz na redução da produção de CH4 entérico, sem causar efeito negativo na degradabilidade de MS e MO, bem como não reduziu a formação total de VFA e atividades bacterianas. Os três diferentes métodos de secagem têm efeito semelhante na redução da produção de CH4, sendo o método de secagem por congelamento o mais eficaz.

Abstract Seaweed plays a significant role in reducing green-house gasses (GHG) emitted by ruminant animals, in particular methane gas (CH4) generated during rumen fermentation of the feed. Euchaema cottonii is one of potential cultivated seaweed in tropical country. A preservation procedure is necessary for further application in CH4 reduction program. The study looked at how three drying methods (sun drying, oven drying, and freeze drying) affected the E.cottonii ability in reducing CH4 methane as measured by an in vitro technique. The addition of dried E. cottonii up to 4% dry matter (DM) was tested using rice straw diets mixed with concentrate in the ratio of 70%:30% in DM base. Measurements was conducted on gas production, degradability and end product of rumen fermentation during 48-hour incubation using a gas production system and ANKOM Daisy II techniques. Overall, the three dried products of E. cottonii found to considerably lower production of CH4, increased DM and OM degradability as well as total VFA production (P<0.05). The three treatments have no effect on NH3 concentration and the bacterial population, but decreased protozoa population (P<0.01). The lowering of CH4 gas production in the rumen is impacted by all three drying methods in the same way. It is concluded that dried E.cottonii addition up to 4% DM effective in depressing enteric CH4 production, without causing negative effect on DM and OM degradability as well as did not depress total VFA formation and bacterial activities. The three different drying-methods have similar effect on reducing CH4 production, with the most affective is freeze-drying method greenhouse green house GHG (GHG animals CH (CH4 feed country program sun Ecottonii E technique 4 (DM 70%30% 7030 70% 30% 70 30 70%:30 base 48hour hour 48 techniques Overall P<0.05.

Resumo O porco-espinho de crista indiano (Hystrix indica) é classificado como uma espécie de praga agrícola. Alimenta-se de plantas e colheitas; portanto, é responsável por enormes perdas financeiras em todo o mundo. O estudo atual foi realizado para avaliar a composição da dieta do porco-espinho de crista indiano nos distritos de Bagh, Azad Jammu e Caxemira (AJ&K). Assim, amostras fecais foram coletadas e examinadas em diferentes locais de amostragem. Lâminas de referência do material coletado na área de estudo foram preparadas para identificação dos componentes da dieta em pellets fecais. Um total de 80 amostras fecais foi coletado e processado. As frequências relativas percentuais (P.R.F.) foram calculadas para cada espécie de planta recuperada de pelotas. Os dados revelaram que o porco-espinho indiano consumiu 31 espécies de plantas em sua dieta, entre elas Zea mays (34,31 ± 7,76) foi a espécie mais selecionada, seguida por Rumex obtusifolius (15,32 ± 2,57) e Melia azedarach (12,83 ± 4,79). O estudo revelou que a maior diversidade de (n = 20) espécies de plantas foi consumida no verão, enquanto o mínimo (n = 13) espécies foi utilizado durante o inverno. Entre as partes das plantas, o caule foi muito consumido na primavera (57,2%) em relação à semente no outono (36,7%), enquanto a espiga e a folha foram as partes menos recuperadas da matéria fecal., O índice de diversidade de Berger-Parker mostrou alimentos altamente diversificados (10,92) no verão do ano em comparação com o outono (2,95). Este estudo fornece uma linha de base para a preferência alimentar dessa praga na área de estudo. Com base nas descobertas atuais, uma investigação detalhada sobre avaliação de danos, exploração, uso de habitat e gerenciamento de porco-espinho de crista indiano em AJ&K foi recomendada.

Abstract The Indian Crested Porcupine (Hystrix indica) is classified as an agricultural pest species. It feeds on plants and crops; hence, it is responsible for massive financial losses worldwide. The current study was conducted to assess the diet composition of Indian Crested Porcupine in District Bagh, Azad Jammu and Kashmir (AJ&K). Thus, fecal samples were collected and examined from different sampling sites. Reference slides of the material collected from the study area were prepared for identification of dietary components in fecal pellets. A total of 80 fecal samples were collected and processed. Percent relative frequencies (P.R.F.) were calculated for each plant species recovered from pellets. Data revealed that Indian Crested Porcupine consumed 31 plant species in its diet, among them Zea mays (34.31±7.76) was the most frequently selected species followed by Rumex obtusifolius (15.32±2.57) and Melia azedarach (12.83±4.79). The study revealed that the greatest diversity of (n=20) plant species were consumed in summer season while minimum (n=13) species were used during winter. Among the parts of plants, stem was highly consumed in spring (57.2%) as compared to seed in fall (36.7%) while spikes and leaf were the least recovered parts from the fecal matter. The Berger-Parker diversity index showed highly diversified food (10.92) in the summer time of the year as compared to the autumn season (2.95). This study provides a baseline for the diet preference of this pest in the study area. Based on current findings, a detailed investigation on damage assessment, exploration, habitat use and management of Indian Crested Porcupine in AJ&K has been recommended.

Resumo A baixa estatura é um problema significativo de saúde pública em países de baixa e média renda. Este estudo avaliou a prevalência de nanismo e os fatores de risco associados de nanismo entre crianças em idade pré-escolar e em idade escolar em áreas afetadas por inundações do Paquistão. Foi realizado um estudo transversal visitando 656 domicílios por meio de amostragem em múltiplos estágios. As medidas antropométricas do entrevistado, informações sociodemográficas e instalações de saneamento foram exploradas. Um modelo de regressão logística foi usado para determinar os determinantes do nanismo, controlando todos os possíveis fatores de confusão. A prevalência geral de baixa estatura em crianças foi de 40,5%, entre as crianças 36,1% dos meninos e 46,3% das meninas com baixa estatura. A prevalência de baixa estatura em crianças menores de 5 anos foi de 50,7%. Crianças do sexo feminino (OR = 1,35, IC de 95%: 0,94-2,0), crianças de 13-24 meses (OR = 6,5, IC de 95%: 3,0-13,9), mães de 15-24 anos (OR = 4,4, IC de 95%: 2,6-7,2), família conjunta (OR = 2,1, IC 95%: 1,4-3,0) não tiveram acesso a água potável de qualidade (OR = 3,3, IC 95%: 1,9-5,9) e a banheiro (OR = 2,8, IC de 95%, 1,9-4,3), enquanto as crianças do distrito de Nowshera (OR = 1,7, IC de 95%: 0,9-3,2) foram significativamente (P < 0,05) associadas na análise univariada. O modelo de regressão revelou que a idade da criança, idade materna, tipo de família, qualidade da água e banheiro foram os fatores significativos (P < 0,05) que contribuíram para a baixa estatura infantil nas áreas afetadas pelas enchentes. A identificação de fatores-chave pode ser útil para os formuladores de políticas no planejamento de programas comunitários abrangentes para a redução da baixa estatura em áreas afetadas pelas enchentes. Em desastres como enchentes, as consequências prejudiciais do problema de baixa estatura podem ser ainda maiores para as crianças. Educação baseada em evidências e cuidados deve ser fornecida às famílias nas regiões afetadas pelas enchentes para reduzir o problema de nanismo. Os determinantes do retardo de crescimento devem ser almejados pela formulação de políticas abrangentes sobre nutrição adequada, meios de subsistência, água potável e instalações de saneamento nas regiões afetadas pelas enchentes.

Abstract Stunting is a significant public health problem in low- and middle-income countries. This study assessed the prevalence of stunting and associated risk factors of stunting among preschool and school-going children in flood-affected areas of Pakistan. A cross-sectional study was conducted by visiting 656 households through multi-stage sampling. Respondent’s anthropometric measurements, socio-demographic information and sanitation facilities were explored. A logistic regression model was used to determine determinants of stunting, controlling for all possible confounders. The overall prevalence of stunting in children was 40.5%, among children 36.1% boys and 46.3% of girls were stunted. The prevalence of stunting in under-five children was 50.7%. Female children (OR=1.35, 95% CI:0.94-2.0), children aged 13-24 months (OR=6.5, 95% CI: 3.0-13.9), mothers aged 15-24 years (OR=4.4, 95% CI: 2.6-7.2), joint family (OR=2.1, 95% CI: 1.4-3.0) did not have access to improved drinking water (OR=3.3, 95% CI: 1.9-5.9), and the toilet facility (OR=2.8, 95% CI, 1.9-4.3), while the children from district Nowshera (OR=1.7, 95% CI: 0.9-3.2) were significantly (P<0.05) associated in univariate analysis. The regression model revealed that child age, maternal age, family type, quality of water, and toilet facility, were the significant (P<0.05) factors contributing to child stunting in the flood-hit areas. Identification of key factors might be helpful for policymakers in designing comprehensive community-based programs for the reduction of stunting in flood-affected areas. In disasters such as flood, the detrimental consequences of the stunting problem could be even more on children. Evidence-based education and care must be provided to the families in the flood-affected regions to reduce the stunting problem. The determinants of stunting should be targeted by making comprehensive policies regarding proper nutrition, livelihood, clean water, and sanitation facilities in flood-hit regions.

Religious beliefs are defined as thinking, feeling and behaving in accordance with the beliefs and teachings of a religious system. In other words, religious beliefs are indicative of the role of religion in the individual and social life of people, as well as adherence to values and beliefs in daily life, performing religious practices and rituals and participating in activities of religious organisations. Religious beliefs are a set of dos and don'ts, and values are considered one of the most important psychological supports that can provide meaning in all moments of life and save a person from meaninglessness by providing explanatory support in specific situations. In addition, work conscience is defined as a feeling of inner commitment to comply with agreed-upon requirements for work. In other words, work conscience means heartfelt satisfaction and practical commitment to the tasks that a person is supposed to perform properly, in a way that there will be no negligence in performing the duty even if no supervisor oversees the activity. Given the significant role of nurses in hospitals, especially during the coronavirus disease 2019 (COVID-19) pandemic, the religious beliefs of healthcare employees have become more important. Therefore, the present study aimed to evaluate the effect of religious beliefs on the work conscience of 1800 Muslim nurses in Iraq during the COVID-19 pandemic in 2021. Standard questionnaires were applied to assess the respondents' religious beliefs and work conscience. In addition, data analyses (Cronbach's alpha, Pearson's correlation, etc.) were performed in Statistical Package for the Social Sciences (SPSS). According to the results, religious beliefs have a positive effect on nurses' work conscience (p = 0.822). CONTRIBUTION: The findings of this study showed that the employees of an organisation, especially nurses and healthcare staff, can rely on their religious beliefs and benefit from their advantages in order to strengthen their work conscience during a hard time such as the COVID-19 pandemic

Metal ceramic restorations are still widely used for prosthodontic rehabilitation of compromised teeth and in general are durable and long lasting. However, post-fitting complications in metal-ceramic crowns and fixed partial dentures do occur. One of the most frequently encountered complications in metal-ceramic systems is the fracture of veneering porcelain, becoming a dental emergency, especially when located in the anterior region. Replacing the entire restoration may not be the most practical solution. Intraoral repair of the fractured porcelain offers an easy and cost-effective alternative. The exact protocol for repair varies with the type of fracture that has occurred. This paper provides an overview of various methods of repairing different types of porcelain fractures with an aim to help clinicians manage these dental emergencies in a more effective and conservative manner.

The study was conducted in Lapai, Niger State, North central Nigeria to determine the profitability of improved maize variety (SAMMAZ 17) in cooperative farmer's fields. Demonstration plots were cited in three cooperative farms where the improved variety and a local variety were planted. All agronomic practices were carried out uniformly and simultaneously on the plots. In addition, structured questionnaires were administered to 20 members of each of the cooperative farms. Participants were selected by means of simple random sampling techniques to solicit information on the performance of SAMMAZ 17 maize variety on their farms. Descriptive statistics were used to analyse the socio-economic characteristics of the farmers, while gross margin analysis was used to compare the profitability of maize varieties. The results revealed that maize farmers were mostly male and small-scale in operations. The local maize variety supported high Striga infestation with low yield of 1.7 t/ha, while SAMMAZ 17 yield was 4.4 t/ha under less Striga infestation. The gross margin production of SAMMAZ 17 maize variety was N 254,127.40, while the gross margin for the production of farmer's maize variety was N 102,517.90. Based on these findings, SAMMAZ 17 was found to be profitable and is therefore recommended for planting in Striga endemic fields in North Central Nigeria.

Reinforced concrete wide shallow beams (WSBs) are commonly used in the joist flooring systems. The structural behavior of WSBs strengthened with carbon fiber reinforced polymer (CFRP) reinforcement was studied on isolated beams and as part of full-scale building. The effect of structural damage on the performance of WSBs flexurally strengthened with CFRP plates was investigated and presented in this paper. Eight full-scale WSBs were tested under four-point bending up to failure. Seven beams were strengthened with CFRP plates bonded to the soffit of the beams and one beam was unstrengthened serving as control. Prior to strengthening, the beams were subjected to different levels of damaging by preloading to 30-95% of the beams' flexural capacity. One beam was fully damaged by preloading to failure and repaired before strengthening by replacing the crushed concrete. The data showed that the pre-damaged strengthened beams exhibited ultimate capacities up to 8% lower than those of the undamaged strengthened beams. However, the load carrying capacities of pre-damaged strengthened beams were more than those predicted by ACI 440 design guide, fib Bulletin 14, and JSCE design recommendations. Both fib Bulletin 14 and JSCE design recommendations gave very conservative predictions with average ratios of experimental to predicted ultimate capacity of 2.02 and 2.35, respectively. More accurate predictions were obtained by ACI 440 design guide as the corresponding ratio was 1.24. These results indicate that strong confidence and reliability can be placed in applying CFRP strengthening to structurally damaged WSBs.

The paper presents a rational procedure for evaluating the concrete shear strength in reinforced concrete beams. Previous research has shown that the shear in concrete is resisted by various mechanisms and the resistance degrades with the increase of flexural deformation. The paper introduces a novel approach in utilizing the knowledge about shear resistance degradation by coupling the shear resistance with the shear demand. Both the shear resistance and shear demand are correlated with flexural tensile strain from compatibility and equilibrium requirements. The basic shear strength, under a given loading is determined from the intersection of the demand and resistance curves. The procedure was verified against a database of 232 beams collected from 10 sources with a broad range of parameters. It showed good prediction capability and can be useful to design practice.

The paper presents the results of an investigation on the diagnosis and assessment of a full-scale reinforced concrete floor utilizing a 3-D forensic model developed in the framework of plasticity-damage approach. Despite the advancement in nonlinear finite element formulations and models, there is a need to verify models on nontrivial challenging structures. Various standards on strengthening existing structures consider numerical diagnosis as a major stage involving safety and economical aspects. Accordingly, model validity is a major issue that should preferably be examined against realistic large-scale tests. This was done in this study by investigating a one-story joist floor with wide shallow beams supported on columns. The surveyed cracking patterns on the entire top side of the floor were reproduced by the forensic model to a reasonable degree in terms of orientation and general location. Concrete principal plastic tensile strain was shown to be a good indirect indicator of cracking patterns. However, identifying the underlying reasons of major cracks in the floor required correlating with other key field parameters including deflections, and internal moments. Therefore, the ability of the forensic model to reproduce the surveyed damage state of the floor provided a positive indication on the material models, spatial representation, and parameter selection. Such models can be used as forensic tools for assessing the existing conditions as required by various standards and codes.

En el presente trabajo, aplicamos la Técnica de Fuente Electromagnética Controlada (CSEM) para obtenerla imagen del centro dinámico de la migración de las fracturas, fisuras y grietas de la superficie somera en una nueva área de vivienda en la ciudad de 15 de mayo cerca a El Cairo. Esta zona constituye el centro de la debilidad del subsuelo, que a su vez, interactúacon el centro de peso de la construcción que ha llevado a colapsos catastróficos. La técnica de Control de Fuente electromagnética se ha desarrollado recientemente para monitorearla migración del centro de la debilidad, representados por la acumulación de fisuras y grietas de la superficie somera. Tres perfiles compuestos se han recogido en 2008. Este estudio se ha seguido realizando con dos perfiles en 2010. Uno de estos perfiles se ha repetido para observar los cambios, y el segundo perfil se ha medido entre los otros dos perfiles de 2008. El último perfil se ha realizado para estudiar la relación mutua entre las mediciones de los dos ciclos. Los objetivos de todo el proceso es validar la eficacia de la técnica para recoger los mínimos cambios del centro de la debilidad, y así, estudiar su relación con el centro de peso de construcciones cercanas, para recomendar un procedimiento que reduzca al mínimo la destrucción de los recursosen el sitio de la investigación. Los datos medidos se haninterpretado y representado en gráficos que muestran la distribución de la heterogeneidad de los parámetros geo-eléctricos en el subsuelo; además, en una serie de seccionescruzadas geoeléctrica se representa las frecuenciasutilizadasdurante el estudio. El estudio concluye que (1) el centro de la zona agrietada se mueve hacia arriba cerca de la superficie de la tierra, (2) el contenido de agua está bajando, produciendola sequedad del suelo apoca profundidad, y (3) el sitio se volviómás estable en 2010 que en 2008, sin embargo, los producto de la destrucción siguen susceptiblesa colapsos.Además, la situación refleja la relación entre el contenido de agua y los cambios en el centro de debilidad.

In the present work, we involve the Control Source Electromagnetic (CSEM) Technique to image the dynamic migration center of the near surface fractures, fissures, and cracks in anew dwelling area at 15th of May city close to Cairo. This area forms the center of the zonal weakness of the subsoil, which in turn, interact with the weight center of the construction leading to catastrophic collapses. The control source electromagnetic technique has been developed recently to monitor the migration of the weakness center represented as the accumulative fissures and cracks in the near surface. Three composite profiles of wide and planshet mesh data have been collected in 2008. This survey has been followed by performing two profiles in 2010; one ofthese profiles has been repeated to observe the situation changes, and the second profile has been measured between the other two profiles of 2008. The last profile had been performed to study the mutual relation between the measurements of the two cycles. The objectives of the whole process are to validate the capability of the technique to pick the minor changes of the weakness center, consequently, study its relation to the weight center of the adjacent construction to produce a recommended procedure to minimize the destruction resources at the site of investigation. The measured data has been interpreted and represented in graphs showing the distribution of the heterogeneity of the geoelectric parameters in the subsoil, furthermore, in a series of geoelectric cross section representing the applied frequencies used during the survey. The study concludes that (1) the center of the cracked zone is moving upward closer to the surface of the ground and heaver, (2) the water content is moving downward producing soil dryness at the shallow depths, and (3) the site became more stable in 2010 than 2008, however, the destruction resources remain warning with collapse events. Furthermore, the situation reflects the relation between the water content and the changes in the weakness center.
