Investigation of Dust Chemical Compounds Emitted by Electric Arc Furnace (EAF) with a reuse perspective

In the process of steel production by electric arc furnace (EAF), it is found that 10 to 20 kg of dust was emitted per every ton of produced steel. Concerning the pollution potential of emitted dust and its reuse ability, the present study was aimed to determine the chemical composition of the electric arc furnace dust with a reuse perspective. This study was done in a steel factory equipped with EAF. Local exhaust ventilation system is installed on the furnace and equipped with cyclone and venturi scrubber. To analysis of dust compounds were gathered in a cyclone and those left the system, the samples were taken from the cyclone hopper and exhaust fan outlet. Finally, the samples were analyzed by X-ray diffraction (XRD). According to the results, the trapped dust in the cyclone and scrubber were 226.86 and 44.81 kg/hr, respectively. The results obtained from XRD analysis also showed that about 50% of the dust was formed by Fe2O3. The quotient of other compounds such as CaO, MgO, SiO2, and Zn was more than 30%. Conclusion: the results of this study showed that EAF dust composed of a range of elements with different concentrations. Given the high weight of these compounds, reusing some of these elements can be having a positive impact on health and the economy

The efficacy of the emotion regulation intervention on coping styles in patients with alexithymia

Background and Purpose: Alexithymia that is known as a kind of insufficiency in emotion regulation is a dangerous factor for many mental disorders. This study is conducted to evaluate the effectiveness of emotion regulation intervention on coping styles in patients with the symptoms of alexithymia.Materials and methods: The research method is experimental with the pretest – post-test and control group. The study population has included the B.A students of Kharazmi University in the year 2014. The study sample has been consisted of 40 students who had the symptoms of alexithymia in the Kharazmi University in the year 2014; these students in the scale of alexithymia have been scored higher than 60 and during the interviews they have been approved in terms having the symptoms of alexithymia and the lack of accompanying symptoms. Then, by getting their permission, these people have been randomly assigned in two intervention and control groups (N =20). But with the primary reduction of the sample, the number of participants in each group has been reduced to 12 people. The intervention group has been trained in 8 sessions of emotion regulation intervention training that each session has been lasted for 90 minutes per week. But the control group did not receive any training programs. The research tools have been consisted of the Tehran Coping Styles Inventory of Karvar et al (1989) and Toronto alexithymia of Besharat (2007). After collecting the data, in addition to using the descriptive statistics, the covariance analysis has been used to analyze the data.Results: The data analysis has shown that the emotion regulation intervention will significantly increase the use of problem-focused coping style (p<0.05).  Conclusion: According to the results of this study, the emotion regulation intervention can be an effective method to improve the problems that are associated with alexithymia in the patients who have alexithymia, and it can be considered as a preventive intervention to prevent the bigger problems of the people who have alexithymia

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Perception and Experiences of Rehabilitation Service Providers of Teamwork Barriers in Tehran Province, Iran

Background and Objectives: The team plays a role as one of the crucial indicators in increasing the performance of the organization. Understanding the perspective of teamwork providers in rehabilitation regarding the existing obstacles can help a lot to improve the situation. This study aims to percept and experience rehabilitation service providers about teamwork barriers in Tehran Province, Iran. Methods: This qualitative study was conducted by conventional content analysis. The participants included 15 service providers with different genders and locations of activities from within Tehran Province in a snowball pattern. The data were collected by in-depth and quasi-structured interviews and analyzed by conventional content analysis method and using constant comparison. Results: After analyzing the meaningful statements of the interviewees, 3 sub-themes “regulations”, “procedural” and “executive” emerged and from the integration of these sub-themes, the theme of “obstacles” emerged. Conclusion: Some of the results of this research, such as defects in rehabilitation management, imposing double treatment costs on clients, and weakness of teamwork training in the university, have common results. Also, some phrases, such as not paying attention to the role of the municipality in rehabilitation and the number of rehabilitation trustees have not been mentioned in the interviews. Based on the results, it was found that obstacles based on regulations, processes, and implementation play a role in the development of teamwork in rehabilitation
