Abstract Objective Disasters in developing countries result in higher human and financial losses compared to global standards, with the death rate being 12 times higher than that of developed countries. Many experts attribute the failures in disaster management to the lack of a system for documenting and analyzing disaster management functions and not leveraging the experiences and lessons learned. This study employed a qualitative data collection approach, utilizing semi-structured interviews with managers, deputies, members of operational teams, and individuals affected by the disaster in the area. This research aims to explore the challenges, strengths, and lessons learned from the response to the Khoy earthquake in Iran. Results After conducting 40 interviews and achieving data saturation, we extracted experiences and lessons learned to investigate the performance of responsible organizations in the 2022 Khoy earthquake. The obtained data were categorized into 8 categories and 39 sub-categories. These categories encompassed warning and calling forces, disaster assessment, disaster commanding, emergency housing, supply and distribution of items, organization, and guidance of public participation and charities, psychological support, logistics operations, monitoring, evaluation, documentation, information dissemination, and media management. Planners and operational managers can use the findings to review and revise their action and prevention plans.

Abstract Background and Aims As a debilitating disorder, spinal cord injuries (SCIs) can bring about a range of physical, psychological, and social consequences in individuals and even have effects on their lifestyle indicators. The present study was thus to reflect on lifestyles among people with SCIs developing from accidents and disasters. Methods Using a meta‐synthesis of qualitative research, all articles recruiting qualitative methods to examine patients with SCIs, published from 1990 to 2020, were retrieved by the researchers, good at the Persian and English languages, from the databases of ScienceDirect, MD Consult, Pedro, ProQuest, PubMed, SID, MedLib, Magiran, Scopus, Google Scholar, Iranmedex, the Cochran Library, CINAHL, and Blackwell, tapping the keywords of “spinal cord injury, SCI, manmade disaster, natural disaster, content analysis, concept analysis, thematic analysis, lifestyle, quality of life, QoL, grounded theory, meta‐synthesis, mixed‐methods research, historical research, ethnography, and phenomenology” in both languages for their inclusion in this study and further analyses. Results With reference to the inclusion criteria, 18 articles were extracted, and after all 10 studies in line with the research topic were reviewed and analyzed. Ultimately, six main themes, namely, compromise, self‐reliance, income‐generating activities, mental status, inability, and issues of sexuality were extracted, demonstrating their importance to individuals suffering from SCIs. Conclusion During the initial stages following SCIs, the abilities to engage in participatory practices and individual's power of decision‐making diminish because of physical, social, psychological, and environmental constraints. It was accordingly recommended to have a holistic perspective and respect all aspects of life in individuals with SCIs.

The purpose of the present study was to investigate the effects of errorless and errorful practice on children’s learning of motor skills: The Role of Reinvestment. The statistical population of the present study consisted of all the male elementary school students in the age range of 7-10 in Mashhad in the academic year of 2017-2018. For this purpose, 48 male students in the city of Mashhad, , were selected through an available sample and randomly based on the levels of reinvestment. This study is an applied research and the type of practice protocol in four groups: errorless with high reinvestment tendency, errorful with low reinvestment tendency, errorful with high reinvestment tendency. Retention, transfer, and dual-task tests were conducted after the acquisition phase at 24-hour intervals. To analyze the data in the acquisition, retention, transfer, and dual-task phases, a mixed model variance analysis (ANOVA) 2 (reinvestment levels: high and low) × 2 (practice protocol: errorless and errorful) and LSD post-hoc test were used, and the data were analyzed using SPSS 24 software. The results of the acquisition test showed that all groups had made progress, but two groups, the errorful with high reinvestment tendency and the errorless with low reinvestment tendency, performed significantly better than the other groups on the retention and transfer tests. The two groups of the defectless with low reinvestment tendency and the defectless with high reinvestment tendency performed significantly better than the other groups under pressure conditions. Therefore, it is recommended that physical educators pay special attention to these psychological variables (reinvestment) when designing exercises and training programs for children’s motor skills.

Abstract Background Liver, as a vital organ, is responsible for a wide range of biological functions to maintain homeostasis and any type of damages to hepatic tissue contributes to disease progression and death. Viral infection, trauma, carcinoma, alcohol misuse and inborn errors of metabolism are common causes of liver diseases are a severe known reason for leading to end-stage liver disease or liver failure. In either way, liver transplantation is the only treatment option which is, however, hampered by the increasing scarcity of organ donor. Over the past years, considerable efforts have been directed toward liver regeneration aiming at developing new approaches and methodologies to enhance the transplantation process. These approaches include producing decellularized scaffolds from the liver organ, 3D bio-printing system, and nano-based 3D scaffolds to simulate the native liver microenvironment. The application of small molecules and micro-RNAs and genetic manipulation in favor of hepatic differentiation of distinct stem cells could also be exploited. All of these strategies will help to facilitate the application of stem cells in human medicine. This article reviews the most recent strategies to generate a high amount of mature hepatocyte-like cells and updates current knowledge on liver regenerative medicine.

The aim of this study was to investigate the role of the errorless, errorful and random practice schedules on the acquisition and learning of relative timing in a motor task. 51 male students (age: 22±4 years old) were selected and randomly assigned to four groups (control, errorful, errorless, and random). This study was carried out in five phases: pretest (PRT), acquisition (ACQ), 10-min retention and transfer and 24-hour retention and transfer. In the acquisition phase, a timing task with three different difficulty levels (simple, moderate, and difficult) was practiced in three sessions of 45 trials with feedback by experimental groups. In order to analyze the data, a mixed-design analysis of variance model with repeated measures on each variable was used in the acquisition and retention phases. The one-way analysis of variance (ANOVA) was used in the other phases. The findings of relative timing showed no significant differences among the groups in the pretest (P˃0.05). Additionally, in retention and transfer tests, errorless group had better performance than errorful, random and control groups (P≤0.05). Errorless group performed better than the random and errorful groups in 24-hour transfer test of the secondary task (P≤0.05). These results showed that practice in errorless conditions leads to a better learning of the task and its generalization to new conditions that are consistent with the implicit learning and reinvestment theories

This study presents the adsorption performance indicator for the evaluation of thermal power plant CO2 capture on mesoporous graphene oxide/TiO2 nanocomposite. To begin, this adsorbent was synthesized and characterized using N2 adsorption-desorption measurements (BET and BJH methods), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) and FT-IR spectroscopy. Subsequently, the pure single-component adsorption isotherms measured at 298 K and the Ideal Adsorbed Solution Theory (IAST) solved with direct search minimisation were applied to estimate the selectivity of the synthesized mesoporous graphene oxide/TiO2 nanocomposite for CO2 over N2 and predict CO2 adsorption capacity in the CO2:N2 binary gas mixtures, including the molar ratio of 5:95, 10:90 and 15:85. Finally, the results validated by the breakthrough experiments at a fixed-bed column were applied to estimate the Adsorption Performance Indicator (API) for the evaluation of CO2 separation from N2 in the Pressure Swing Adsorption (PSA) process with respect to different types of thermal power plants.

Serum insulin, preptin, and myostatin levels were measured with immunoradiometric assay (IRMA), enzyme-linked immunosorbent assay (ELISA), and chemiluminescent immunoassay (CLIA), respectively. Patients with T2DM had higher levels of preptin compared to normoglycemic (461.25±53.90 vs. 407.54±54.78, P

Objective(s): Empagliflozin, a sodium-glucose cotransporter-2 (SGLT-2) inhibitor, possesses verified anti-inflammatory and anti-oxidative stress effects against diabetic nephropathy. The present investigation aims to examine empagliflozin effects on the renal levels of high mobility group box-1 (HMGB1), a potent inflammatory cytokine, and its respective receptor toll-like receptor-4 (TLR-4) in STZ-induced diabetic rats.Materials and Methods: Empagliflozin at 10 mg/kg per os (p.o.) was administered for 4 weeks, starting 8 weeks after the induction of diabetes. Renal function, kidney inflammation, oxidative stress, and apoptosis markers as well as renal HMGB1, receptor for advanced glycation end products (RAGE), and TLR-4 levels were assessed.Results: In addition to down-regulating NF-κB activity in renal cortices, empagliflozin reduced renal levels of HMGB1, RAGE, and TLR-4. It alleviated renal inflammation as indicated by diminished renal expressions of inflammatory cytokines and chemokines like tumor necrosis factor-alpha (TNF-α) and monocyte chemoattractant protein-1 (MCP-1) and also decreased urinary levels of interleukin-6 (IL-6) and alpha-1 acid glycoprotein (AGP). Moreover, empagliflozin ameliorated renal oxidative stress as demonstrated by decreased renal malondialdehyde (MDA) and elevated renal activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX). It also suppressed renal caspase-3, the marker of apoptosis; and furthermore, enhanced renal function noticed by the declined levels of serum urea and creatinine.Conclusion: These findings underline that empagliflozin is able to attenuate diabetes-related elevations in renal HMGB1 levels, an influential inflammatory cytokine released from the necrotic and activated cells, and its correspondent receptors, i.e., RAGE and TLR-4.

Objective(s): Cisplatin is an effective antineoplastic agent; its clinical utility, however, is limited by a few salient toxic side effects like nephrotoxicity. This study aimed to determine the potential protective effects of tangeretin, a citrus-derived flavonoid, against renal tubular cell injury in cisplatin-induced renal toxicity of rats.Materials and Methods: Tangeretin was injected intraperitoneally at 2.5 and 5 mg/kg doses for 10 days, and a single dose of cisplatin (8 mg/kg) was injected on the 7th day. Tests of kidney function and tubular injury in renal tissues and urine together with oxidative stress and inflammation markers were examined.Results: Tangeretin ameliorated cisplatin-induced elevations in serum creatinine, BUN, and histopathologic changes. It also attenuated kidney oxidative stress elicited by cisplatin as demonstrated by reduced MDA and increased GSH, CAT, and SOD activities, elevated Nrf2 expression and protein levels of its downstream effectors, HO-1 and NQO-1. Tangeretin further alleviated inflammation evoked by cisplatin as indicated by reduced NF-κB p65 subunit phosphorylation with a simultaneous decrement in its downstream effectors IL-1β and TNF-α expression and protein levels. Moreover, it declined caspase-3 protein levels and TUNEL positive cells in the kidneys, the markers of apoptosis and DNA fragmentation, thus improving renal endurance. Additionally, tangeretin mitigated renal levels of KIM-1 and NGAL, as well as urinary cystatin C and β2-microglobulin concentrations, the markers of renal tubular injury.Conclusion: Collectively, these data signify the binary profit of tangeretin: enhancement of renal protective mechanisms against cisplatin and attenuation of renal tubular cell injuries induced by the agent.

Background. Mental skills are defined as a set of trainable mental abilities and methods that are held to underpin successful learning and performance. Objectives. The aim of the present research was to study and compare the mental skills of adolescent elite and competitive volleyball and soccer players. Methods. The sample consisted of 100 players (54 elite soccer, 13 elite volleyball, 18 competitive soccer and 15 competitive volleyball) selected via a purposive sampling method. Data were collected using the Ottawa Mental Skills Assessment Tool-2 (OMSAT-2). Results. Elite and competitive volleyball players had higher scores for stress reactions than elite soccer players. In addition, elite soccer players had more self-confidence than competitive soccer and volleyball players. Also, competitive volleyball players had higher levels of fear than elite soccer players. There were no other significant differences in mental skills between soccer and volleyball players. Conclusion. It seems that adolescent volleyball players stand in more immediate need of learning strategies for coping with stress, fear and self-confidence management than soccer players. Results are discussed in terms of an athlete’s levels, the nature and characteristics of the sport and choking during performance.

Protectorate of the children without guardian is an ethical and God-favored work which cause that such children experience the warm center of family, but since children without guardian don’t have any natural relationship with child adopting parents, they have only a legal relationship no privacy is established between them; in terms of juridical commandments, It is the possibile the marriage of the guardian with the child who he has adopted, although such act by change of the look in the individuals towards guardianship of children lacking protector from a charitably act to a profiteering act and creation of agitation in the mentality of the child herself and the society to convert from a fatherhood - childhood relationship in to marriage relationship, is contrary to good morals and the public policy of society . In this research we seek to consider juridical resources, we examine the possibility of extinguishment such marriage right with the adoptedchild” as a juridical solution. Although the two points of view about extinguishment” and “ non-extinguishment” of the marriage right of the guardian with the adoptedchild between Muslim jurisconsults, but considering its documentations confirms the second point of view, since marriage, the same as custody, in one way is judicial sentence.

As the pharmaceutical services are growing these days, author witness an increase in relationship between the pharmacists and patients. So, the legitimacy of their interaction plays an important role. In the present article, in addition to introducing the ethical principles governing the pharmacist-patient interaction, certain ethical challenges associated with these principles are also addressed. These principles have been categorised into six groups based on medical ethics.

This study aimed at investigating the effect of blocked, incremental systematic and random contextual interferences on acquisition, retention and transfer of volleyball skills based on changes in a generalized motor program. In fact, this study was conducted to answer this question that whether regular increment of contextual interference level is more effective on learning volleyball service skill than blocked or random practice schedules. 30 students (mean age 23±4 yr, 3 groups and each 10 subjects) participated in this study. The groups were different in practices of the three services. Subjects performed simple, overhead and single arm skills from a distance (9 m from the volleyball net) with different practices. Each participant practiced 108 trials of each service, totally 324 trials during 9 sessions (each session 36 trials). The results indicated that incremental practice resulted in a better performance in retention and transfer tests than blocked and random practices (P˂0.05). In general, it was suggested that the practice should be scheduled so that it can start from low interference and gradually and systematically continues towards high interference in order to facilitate learning of several generalized motor skills.

Efficacy of fomesafen and storm (bentazone+aciflorfen) herbicides on common bean (phaseolus vulgaris L.) weed control were evaluated in a randomized complete block design with four replications during 2008 in Lorestan Province. Herbicides were applied postemergence at three trifoliate growth stage of common bean. Herbicide injury on weeds reached maximum three days after treatments and common bean was recovered from initial injury of herbicides especially their combinations with high dose at 14 days after treatments, so that treatments had no persistent injury effect on crop. Tank mixture of fomesafen (1.5 L.ha-1) and storm (1.5 L.ha-1) treatment controlled weeds by 71.3% and based on visual injury monitoring, this mixtures controlled Physalis divaricata, Hibiscus trionum, and Portulaca oleracea 92.8, 81.3, and 63.8%, respectively. In general, visual evaluation 14 days after treatments, fomesafen (1.5 L.ha-1) mix with storm (1 or 1.5 L.ha-1) controlled weeds by 80% and it was not significantly differed from hand weeding. Results of this research indicated that fomesafen and storm herbicides, and their combinations at proposed doses may apply postemergence for weed control in common bean.

Urban air quality management is critically dependent on robust air quality monitoring systems. Conventional systems, utilizing fixed, complex, and costly equipment, encounter challenges in stable data collection, transmission, and accessibility. Recent scholarly reports have highlighted the potential of low-cost sensors as an alternative to these conventional systems. This study endeavors to ascertain the optimal placement of low-cost PM2.5 monitoring sensors in Tehran. The methodology involved a two-step process. Initially, PM2.5 pollution maps of Tehran were generated utilizing data from local air quality monitoring stations and remote sensing data. Owing to its superior accuracy and comprehensive coverage, remote sensing data was employed for determining the optimal sensor placement. Subsequently, the Gaussian process model was utilized to optimize sensor locations. The initial placements were based on a scenario where a 1 × 1 km grid was defined for the initial placement of sensors. This scenario involved dividing the city into equal grids and choosing the center of each grid as the point for placing the sensor. The preliminary sensor placement considered a uniform distribution across Tehran at regular one-kilometer intervals. Following this, the Gaussian process model identified 592 optimal locations for the installation of low-cost PM2.5 monitoring sensors. The study concludes that the strategic deployment of low-cost sensors, guided by the Gaussian process model, can significantly enhance the effectiveness of urban air quality monitoring systems. It is strongly recommended that urban authorities consider the integration of low-cost sensors at the identified locations for more efficient and economical air quality monitoring.Highlights: The GP model was used to optimize the location of LCS for urban PM2.5 monitoring. PM2.5 pollution maps of Tehran city were produced using AQMS and RS data. 592 optimal locations were selected to install LCS for urban PM2.5 monitoring in Tehran city. [ABSTRACT FROM AUTHOR]

Thermal power plants are one of the main sources of CO2 emissions in the world. On the other hand, increasing carbon dioxide emissions as a greenhouse gas is led to global warming and climate change. In this study, CO2 mitigation strategies for Iran's thermal power plants regarding Intended Nationally Determined Contributions submitted by Iran using modified STIRPAT model examines are presented. In the first step of this research, CO2 emissions from Iran's power sector are predicted with respect to the parameters including, population, GDP, and electricity generation. In the second step of this research, CO2 mitigation strategies including, using the renewable sources and increasing energy saving as well as power generation efficiency during the years of 2020 to 2025 are analyzed using modified STIRPAT model to reduce carbon dioxide emissions in accordance with Iran's INDCs. The prediction of carbon dioxide emissions by 2025 represents an increase of 26.5% in carbon dioxide emissions compared to 2017 while estimating carbon dioxide emissions in accordance with Iran's INDCs allows a maximum increase of 21.4% compared to 2017. In order to reduce carbon dioxide emissions, the average efficiency of power plants by 2025 should be 1.542% higher than in 2017, or 3.086% of the energy savings should be implemented compared to total electricity generation output projected in 2025, or more than 36.22% increment of electricity generation output from renewable energy is expected compared to the projected level in 2025, or a combination of these three solutions.

Regardless of the non-requirement of respecting Qebteh in some possessions, such as affairs related to guardian's affairs, payment of living expenses, education, etc., according to the opinion of famous jurists, the guardian's possessions in other affairs of the Movalli Alaiih are subject to respecting his Qebteh. Nevertheless, the boundary between the concept of Qebteh and related words and the mechanism of its recognition in jurisprudence texts is not very clear. Using the analytical and descriptive method, the present essay shows that, from the point of view of jurisprudence, Qebteh has a concept that is compatible with expediency and incompatible with benefit, and it is a real condition in the guardian's possession.Observance of Qebteh is valid in all financial and non-financial possessions of the guardian, and its recognition and application in financial affairs is the duty of the institution that has the necessary substructure for such recognition. In case of conflict between interests, priority is given to an act that guarantee's definite and long-term benefit and includes the worldly and hereafter interests of the Movalli alaiih. The best criterion for recognition of respecting Qebteh is to guarantee the preservation of his rights following the action of the guardian; Rights that can be found in religious teachings, statutes and international documents.

Some Sunni jurists have made jurisprudential use of the historians' reports in the Sirah books (books about infallible’s life). While the Jaʿfari (Imamiyya) jurists do not want to infer to historical sources in their jurisprudence inference. Since historical books can provide jurists with a lot of data about the speech and behavior of infallibles, it seems necessary to investigate the possibility of citing the reports of historians in jurisprudential inferences. Therefore, in the present study, we try to answer the question of whether the historians' reports of the lives of the infallibles can be considered an independent reason in jurisprudential inference. The findings of the present research, which was carried out by descriptive-analytical method and based on library data, it shows that although the four titles "khabar vahed" (single news), "expert's opinion", "khabar motavater" (frequent news) and "instead" (blocking in Islamic sources) can be used as proofs of the authenticity of the historian's report. But according to the limitations and methodological problems in historical sources, only by accepting the validity of "Ensedad" in historians' reports, historical sources can be considered as one of the jurisprudential reasons for inferring imperative rule or positive rules.
