Comparison of the quality of life, psychological well-being, and emotional self-regulation among nurse with non-nurse women in Imam Khomeini hospital, Kuhdasht City, Iran

BACKGROUND: In the hospital, nurses are exposed to high levels of psychological stress. The purpose of this study was to compare the quality of life, psychological well-being, and emotional self-regulation of nurse and non-nurse women in Imam Khomeini hospital in Kuhdasht City, Iran.METHODS: This was a descriptive prospective causal-comparative research. The statistical population of this study was all the women staff of Imam Khomeini hospital in Kuhdasht in 2018. A sample population of 100 nurse women was selected using convenience sampling method, and 100 non-nurse women were selected via random sampling method. The instruments used in this research were 36-Item Short Form Health Survey (SF-36) Quality of Life, Reef Psychological Well-Being, and MARS emotional self-regulation questionnaires. Data were analyzed using multivariate analysis of variance (MANOVA) (P < 0.050).RESULTS: The MANOVA test showed a significant difference between quality of life, psychological well-being, and emotional self-control between nurse and non-nurse women (P < 0.050). This meant that nurse women in the studied variables were lower than their non-nurse counterparts.CONCLUSION: According to the results of this research, it is suggested that in nursing mental health promotion programs, education should be considered in order to improve the quality of life, psychological well-being, and emotional self-regulation of nurses

Investigation and comparison of Gardner’s multiple talents in sighted and blind male students in Tehran’s guidance schools (90-91).

Objective: The aim of the study is to investigate and compare multiple talents of the sighted and blind male students in Tehran’s guidance schools.Method: This study is a survey. The statistical population of this study includes all the sighted students and blind students of Tehran’s Guidance schools. Stratified sampling for the sighted and available sampling for the blind has been used in this study (60 blind and 60 sighted students) .Gardner multiple talents questionnaire has been applied. The obtained data was analyzed and compared using the independent t-test between two groups.Results: The results show that no statistically significant differences exist between the two groups regarding their talents (p>%5).Conclusion and recommendations: The blind, though lacking visual ability, are able to compensate for the deficit through other senses. It is highly recommended that the blind’s capabilities be identified and taken into account in education

Removal of microplastics from the environment. A review

International audienceThe production of fossil fuel-derived, synthetic plastics is continually increasing, while poor plastic waste management has recently induced severe pollution issues. Microplastics are plastic particles smaller than 5 mm. Microplastics are ubiquitous and slowly-degrading contaminants in waters and soils. Microplastics have long residence time, high stability, high potential of being fragmented and can adsorb other contaminants. Many aquatic species contain microplastics, which are in particular easily accumulated by planktonic and invertebrate organisms. Then, microplastics are transferred along food chains, leading to physical damages, decrease in nutritional diet value and exposure of the living organism to pathogens. Raw plastics contain chemical additives such as phthalates, bisphenol A and polybrominated diphenyl ethers that may induce toxic effects after ingestion by living organisms. Furthermore, the adsorption capability of microplastics makes them prone to carry several contaminants. Methods to remove microplastics from water and other media are actually needed. Here, we review microplastics occurrence, transport, raw polymers and additives, toxicity and methods of removal. Removal methods include physical sorption and filtration, biological removal and ingestion, and chemical treatments. Mechanisms, efficiency, advantages, and drawbacks of various removal methods are discussed

Hexagonal Core-Shell SiO2[-MOYI]Cl-]Ag Nanoframeworks for Efficient Photodegradation of the Environmental Pollutants and Pathogenic Bacteria

Hexagonal core-shell SiO2[-MOYI]Cl-]Ag nanoframeworks were synthesized via surface modification of hexagonal silica nanoparticles prepared from perlite (EP) as a cheap and abundant raw material. The prepared samples were well characterized by X-ray diffraction powder (XRD), energy dispersive X-ray (EDX), diffuse reflectance spectroscopy (DRS), Brunauer-Emmett-Teller (BET) specific surface area analysis, fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM). The XRD patterns confirmed that Ag and AgCl crystalline phases were successfully loaded on the surface. The TEM images were also implied that the nanoparticles have hexagonal shape with the average size of 50-80nm. Photocatalytic properties were evaluated by degradation of acid blue 92 (AB92), two semivolatile organic compounds (SVOCs) i.e., 4-methoxy-2nitrophenol (4Mx2Np) and 3-methyl-4-nitrophenol (3M4Np), and Staphylococcus aureus (S. a) gram positive bacteria under visible light. The kinetics and mechanism of the photocatalytic pathways were also studied and the results were discussed. According to the obtained results, the photocatalyst was incredibly able to degradethe contaminants under visible light. Recycling experiments described the high capacity of the prepared sample for the repeated treatment of wastewaters.The TEM images of the treated bacterial cell walls after the reaction time were also used to clarify the antibacterial activity of the samples

Highly efficient nitrobenzene photoreduction over the amino acid-modified CdS-TiO2 nanostructures under visible light

CdS-coupled TiO2 nanocrystals were prepared by the microemulsion-mediated solvothermal method at pretty low temperatures. The semiconductor nanocrystals were modified with tyrosine, phenyl alanine, glysine and glutamate aminoacids and then were characterized by BET, SEM, EDX, XRD, UV–Vis spectroscopy, and FTIR analysis methods. The specific surface area and the average pore diameter were found to be about 470 m2 g−1 and 2.8 nm, respectively. Moreover, the average size of the CdS-TiO2 particles was evaluated to be 28 nm. The results showed that the modification process with the aminoacids improves the adsorption capability and photoactivity of the samples. Among them, tyrosine was determined to be the best choice. According to the results, modification of CdS-TiO2 heterojunction photocatalyst with electron-donating groups is an efficient strategy to increase the photoreduction of nitroaromatic compounds. Reusability experiments were also carried out and confirmed the high capacity of the prepared samples for the photoconversion of nitrobenzene after being repeated for four times
