Background & Aims:The emergency department is the most stressful work environment in the hospitals and the prevalence of stress among its staff is very high.Nurses often struggle to control their negative emotions in such stressful environments.This study aimed to investigate the effect of stress management training on anger control of nurses working in the emergency department of Imam Khomeini Hospital in Naghadeh city in 2023. Materials & Methods:This quasi-experimental study was conducted as a pre-test-post-test design.Forty nurses from the emergency department were selected through census sampling to participate in the study.Data were collected using a demographic questionnaire and the Springer Anger Control Skills Questionnaire, both before and after stress management training.The data were analyzed using SPSS version 26 at a 95% confidence level, with a significance threshold of P < 0.05.Results: Based on demographic characteristics, the mean age of the studied samples was 29.32 5.22 years and most of them (65%) were male.The results of the paired t-test showed that in the post-test, the mean scores of anger significantly decreased (t(39)=3.46;P 0.001) and the mean scores of anger control of nurses significantly increased (t(39)=5.00;P 0.001). Conclusion:The results showed that stress management skills training was effective in reducing anger and enhancing anger control in nurses working in the emergency department.Therefore, implementing stress management training programs for nurses working in the emergency department seems beneficial and necessary How to cite this

The increasing global emphasis on sustainable construction practices has spurred significant international research into developing durable and eco-friendly concrete materials. This study investigates the potential of metakaolin and glass powder as supplementary aluminosilicate materials in slag- based geopolymer mortars, aiming to enhance their mechanical properties and durability. To further improve the performance, polypropylene fibers were incorporated at various dosages. Therefore, 13 mixtures of geopolymer mortar based on blast furnace slag have been developed. The control mix does not contain fibers or slag replacement materials, whereas in the other formulations, glass powder and metakaolin have been employed as substitutes for slag at weight percentages (relative to the weight of slag) of 5% and 10%, separately and in combination. Additionally, the fiber-containing samples are divided into two groups based on the volume percentage of polypropylene fibers, comprising 0.2% and 0.4%. The results of the investigation show that the use of glass powder, particularly at a replacement percentage of 10%, leads to an improvement in the 28-day compressive strength. Furthermore, the mixes containing glass powder demonstrated higher flexural strength compared to those containing metakaolin, irrespective of the volume percentage of fibers. The best performance in the rapid chloride permeability test is associated with the mix containing a combination of glass powder and metakaolin at a replacement percentage of 10%. Satisfactory results have been obtained when using fibers at volume percentages of 0.2% and 0.4%. Additionally, this study utilized a fuzzy inference system to predict compressive strength. The results indicate that, by considering uncertainties, the compressive strength of the mortar can be predicted with an error of less than 1% without the need for complex mathematical calculations.

The increase in population and the challenges caused by it are always among the concerns of decision-makers and policymakers in large countries. One of the most serious concerns is in the field of energy consumption. Optimizing energy use is one of the most effective ways to manage limited resources and energy. Energy consumption in residential houses constitutes a significant percentage of the total energy consumption worldwide; therefore, current research focusing on mathematical models aims to provide a predictive multi-objective linear mathematical model for residential house consumption. For this purpose, the consumption of water, electricity, and gas for 80 residential houses, including 10 household appliances and equipment on a weekly basis, has been considered. The results showed that the mixed-integer multi-objective predictor model is able to optimize household consumption plans compared to the actual state of household energy consumption. Since the goals of household satisfaction and energy consumption costs in the model conflict with each other, the influence coefficient was calculated to demonstrate the simultaneous achievement of these goals. The optimal value achievable with the default model for the model&amp;#039;s purposes is 69%.

The movement of the construction industry towards sustainable development has drawn attention to the revision of concrete. In addition to reducing pollution, the use of nano-materials should lead to the provision of higher quality concrete in terms of regulatory items (workability, resistance characteristics, durability characteristics, microstructure). The present study investigates 15 key characteristics of concrete modified with nano-CaCO3, nano-clay, nano-TiO2, and nano-SiO2. The results of the study showed that nanomaterials significantly have a positive effect on the hydration mechanism and the production of more C-S-H gel. The evaluation of resistance characteristics also indicates the promising results of these valuable materials. The durability characteristics of nano-containing concrete showed significant improvement despite high dispersion. Concrete in coastal areas (such as bridges or platforms), concrete exposed to radiation (such as hospitals), concrete exposed to impact load (such as nuclear power plants), and concrete containing recycled aggregate (such as bricks, tiles, ceramics) can be effectively improved by using nanomaterials. It is hoped that the current review paper can provide an effective image and idea for future applied studies by other researchers.

Endangerment as a criterion for those behaviours that can potentially and potentially threaten the health and safety of individuals in the future is a criterion that considers the behaviour worthy of attention regardless of the outcome. This criterion can provide a comprehensive model in describing (wrongdoing or criminalization) behaviours against health and safety, according to the basic philosophical principles in the principle of injury by referring to possible injuries and their classification. This article seeks to answer the fundamental question of how and by what approach can a significant number of immunosuppressive behaviours be envisioned as a criterion of risk in criminal law by explaining the income based on the description of the risk criterion. It seems that the Iranian legislature, by dividing the legal instances of risky behaviours, not only deviates from the goals of systematic description, i.e. social safety, but also pays attention to the need to separate instances of error from crime and systematic possible degrees of risk in regulations and adjust the position of criminal law in ensuring safety and preventing risky behaviours.

In this study, different engineered cementitious composite (ECC) designs were proposed with ground granulated blast slag (GGBS) combined with metakaolin (MK), micro silica (MS), and carbon nanotube (CNT) reinforced with polyvinyl alcohol (PVA) and polypropylene (PP) fibers. The specimens were cured in water, magnesium sulfate solution and exposed to freeze–thaw cycles to test the specimens' durability. Then, compressive strength, displacement in the middle of span, residual strength, and modulus of rupture of the specimens in different environments were compared. The results indicated that addition of MK had a significant effect on the reduction of permeability. Moreover, replacement of PP fibers with PVA fibers decreased the strength and increased the porosity of the specimens. It was found that the specimen containing 0.015% CNT had better performance compared to other samples. The results of samples cured in aggressive environments indicated that the specimen containing 0.015% CNT had the lowest loss in the value of compressive strength, modulus of rupture, displacement and residual strength in comparison to other mixtures. Furthermore, the use of CNT along with PVA fibers in ECC significantly increased the energy absorption capacity, indicating the CNT's ability to bridge and close the micro-cracks in a case of suitable distribution.

Together with offering a review of recent studies on the forced conversion of Jews and Christians that took place under the Almohads, this contribution aims at highlighting the need to understand such episode and its treatment in the few sources that mention it as part of what the Almohads stood for in the early stage of their movement. Changes in their political and religious policies affected the way the episode was remembered and talked about, as it provoked both anxiety and embarrassment. Additional information allows us to explore the impact forced conversion had in the preoccupation with Jewish ancestry and the interest in portraying converts from Judaism in a positive light. Finally, how the Muʼminids towards the end of their rule faced the issue of conversion from Islam to Christianity is explored.
