Optimizing linear alkyl benzene sulfonate removal using fenton oxidation process in taguchi method

Linear alkyl benzene sulfonate (LAS), which is the most common used anionic surfactant in detergents manufacturing, can discharge onto water resources through wastewater and causes change in taste and odor, disruption in water treatment processes, aquatics death, and oxygen transfer limitation. Accordingly, this article investigates to optimize LAS removal using Fenton oxidation process in Taguchi Method for the first time. LAS removal using Fenton oxidation was perused experimentally in a lab-scale reactor

A practice-inspired mindset for researching the psychophysiological and medical health effects of recreational dance (dance pport)

“Dance” has been associated with many psychophysiological and medical health effects. However, varying definitions of what constitute “dance” have led to a rather heterogenous body of evidence about such potential effects, leaving the picture piecemeal at best. It remains unclear what exact parameters may be driving positive effects. We believe that this heterogeneity of evidence is partly due to a lack of a clear definition of dance for such empirical purposes. A differentiation is needed between (a) the effects on the individual when the activity of “dancing” is enjoyed as a dancer within different dance domains (e.g., professional/”high-art” type of dance, erotic dance, religious dance, club dancing, Dance Movement Therapy (DMT), and what is commonly known as hobby, recreational or social dance), and (b) the effects on the individual within these different domains, as a dancer of the different dance styles (solo dance, partnering dance, group dance; and all the different styles within these). Another separate category of dance engagement is, not as a dancer, but as a spectator of all of the above. “Watching dance” as part of an audience has its own set of psychophysiological and neurocognitive effects on the individual, and depends on the context where dance is witnessed. With the help of dance professionals, we first outline some different dance domains and dance styles, and outline aspects that differentiate them, and that may, therefore, cause differential empirical findings when compared regardless (e.g., amount of interpersonal contact, physical exertion, context, cognitive demand, type of movements, complexity of technique and ratio of choreography/improvisation). Then, we outline commonalities between all dance styles. We identify six basic components that are part of any dance practice, as part of a continuum, and review and discuss available research for each of them concerning the possible health and wellbeing effects of each of these components, and how they may relate to the psychophysiological and health effects that are reported for “dancing”: (1) rhythm and music, (2) sociality, (3) technique and fitness, (4) connection and connectedness (self-intimation), (5) flow and mindfulness, (6) aesthetic emotions and imagination. Future research efforts might take into account the important differences between types of dance activities, as well as the six components, for a more targeted assessment of how “dancing” affects the human body

Extra-corporeal membrane oxygenation for refractory cardiogenic shock after adult cardiac surgery:a systematic review and meta-analysis

Background - Postcardiotomy cardiogenic shock (PCCS) refractory to inotropic support and intra-aortic balloon pump (IABP) occurs rarely but is almost universally fatal without mechanical circulatory support. In this systematic review and meta-analysis we looked at the evidence behind the use of veno-arterial extra-corporeal membrane oxygenation (VA ECMO) in refractory PCCS from a patient survival rate and determinants of outcome viewpoint. Methods - A systematic review was performed in January 2017 using PubMed (with no defined time period) using the keywords “postcardiotomy”, “cardiogenic shock”, “extracorporeal membrane oxygenation” and “cardiac surgery”. We excluded papers pertaining to ECMO following paediatric cardiac surgery, medical causes of cardiogenic shock, as well as case reports, review articles, expert opinions, and letters to the editor. Once the studies were collated, a meta-analysis was performed on the proportion of survivors in those papers that met the inclusion criteria. Meta-regression was performed for the most commonly reported adverse prognostic indicators (API). Results - We identified 24 studies and a cumulative pool of 1926 patients from 1992 to 2016. We tabulated the demographic data, including the strengths and weaknesses for each of the studies, outcomes of VA ECMO for refractory PCCS, complications, and APIs. All the studies were retrospective cohort studies. Meta-analysis of the moderately heterogeneous data (95% CI 0.29 to 0.34, p 70 years, 95% CI −0.057 to 0.001, P = 0.058), and long ECMO support (95% CI −0.068 to 0.166, P = 0.412). Postoperative renal failure, high EuroSCORE (>20%), diabetes mellitus, obesity, rising lactate whilst on ECMO, gastrointestinal complications had also been reported. Conclusion - Haemodynamic support with VA ECMO provides a survival benefit with reasonable intermediate and long-term outcomes. Many studies had reported advanced age, renal failure and prolonged VA ECMO support as the most likely APIs for VA ECMO in PCCS. EuroSCORE can be utilized to anticipate the need for prophylactic perioperative VA ECMO in the high-risk category. APIs can be used to aid decision-making regarding both the institution and weaning of ECMO for refractory PCCS

Relation of five basic factors of personality and self Regulated of learning approach among Isfahan girls and boys high school students in academic year 1386-87

This research has studied the relation between five basic factor of personality and self- regulated approach of learning. Research sample consisted of 175 students (83 boys and 92 girls) who were selected randomly out of five Isfahan educational districts high school. To measure five factors of personality NEO-FFI and for self-regulated approaches, MSLQ questionnaires were used. Results of variance analysis showed that there is no significant difference between learning approaches averages of girls and boys students(

Investigating the Role of Socio-Economic Factors Affecting Happiness: A Case study of the Active Population of Tehran Jafar Mikaeili , Morteza Khorsandi , Fatemeh Homayouni

Abstract Reports and statistical data indicate the critical state of Iran in terms of happiness and its related indexes. On the other hand, a tumultuous lifestyle in a metropolis such as Tehran makes people susceptible to being depressed and unhappy. An increasing speed of life and many social and economic problems threaten the psychological health of people and affect the society in different social, economic and cultural dimensions as a result. This study is a correlational and cross-sectional one, which is performed using a survey method for the active population of Tehran (15-65 years) with a sample of 371 members (multistage cluster sampling). Accordingly, in this study, we seek to answer the question of “how social variables (social capital, social trust, social coherence and Social participation) and economic variables (unemployment and income) affect the active population's happiness in Tehran?”. To analyze the data, descriptive statistical analysis methods, inferential statistics and path analysis method are used. The results indicated that, there was a significant positive correlation between “social coherence, social   participation and social trust” and “happiness”. Also, between “household income and age” and happiness. According to other results, there was no significant relationship between “educational level, employment status, gender and marital status of people” and “happiness”. Altogether, the path analysis model shows “social coherence, social participation, social trust, household income” has a significant positive effect on people's happiness and these variables can make up for 34 percent of the total variance of “happiness” changes. KeyWords: Happiness, Social Capital, Social Trust, Social Coherence, Social Participation, Income, Unemployment
