RECAST SEEN THROUGH MULTIPLE INTELLIGENCES’ LENS
There has been a host of research on recast so far, despite which it is still controversial if it is any effective. The main argument against recasts is that they often go unnoticed by students due to their implicit nature. It is hypothesized in the light of the theory of Multiple Intelligences (MI) that certain intelligences might affect the noticeability of recasts. Therefore, this paper aimed to find if certain intelligence help learners notice recasts. To fulfill this, 121 pre-intermediate EFL learners in 9 different classes were selected using convenience sampling. A questionnaire was used to measure their MI. Moreover, they were observed for 104 hours for the occurrence of recast and uptake using a checklist. For data analysis, multiple regression was used to find out if any components of MI were significant predictors of recasts’ success in leading to uptake. The results indicated that musical, visual, and verbal intelligence significantly predicted whether recasts will be perceived by students as corrective feedback. Therefore, it was concluded that it is essential to build MI into the picture when evaluating the efficacy of recasts on the grounds that students with certain dominant intelligence benefit from subtle clues which in turn help them notice recasts
Recent advances on happiness
Happiness plays essential role on building prosperity and success in any society. Happiness is one of the essential factors to reach prosperity and success in people’s life and jobs but happiness is not always the same as capability, but they may be correlated while capability is a necessary for having a happy life and happiness feeds back on capability in different ways. People who feel happy could better contribute to society and help other people build better future. This study performs a review on recently completed studies on factors, which influence happiness, new definitions of happiness. The study concentrates more on empirical investigations on the concept of happiness
Investigating the relationship between the level of serum albumin and body mass index, as nutritional indicators, with dialysis adequacy in patients under hemodialysis
BACKGROUND: Patients with end-stage renal disease (ESRD) who undergo hemodialysis have many complications; one of the most important of which is malnutrition, which affects these patients’ quality of life. The aim of this study was to evaluate serum albumin and body mass index (BMI) as nutritional indicators, and their relationship with dialysis adequacy in patients under hemodialysis.METHODS: In this study, 100 patients who underwent hemodialysis in Razi Hospital, Qaemshahr City, Iran, in 2016 were selected via convenience sampling method. The data were collected using demographic questionnaire, albumin test, and measuring height and weight of patients. Data were analyzed using linear regression and correlation coefficient tests.RESULTS: The correlation between the hemodialysis adequacy with albumin was 0.634, which was significant (P < 0.050). For the second hypothesis, the quality of dialysis with BMI was not positively correlated. The correlation between the hemodialysis adequacy with BMI was -0.007, which was not significant (P > 0.050). Although, in the third hypothesis, the regression between the adequacy of hemodialysis, as a dependent variable, and serum albumin and BMI, as independent variables, indicated significant relationship between serum albumin and hemodialysis adequacy; but there was no significant relationship between BMI and adequacy of hemodialysis.CONCLUSION: Adequacy of hemodialysis is in relationship with malnutrition and improving the KT/V dialysis adequacy may have a significant effect on the malnutrition control in these patients

KARTIRANJE LISKUNASTE ŽELJEZNE RUDE I IZRADA PRIMJENJIVIH INDUSTRIJSKIH STANDARDA
The purpose of this study is to determine the appropriate method for micaceous iron ore processing and production per-industrial application standards. After identifying the characteristics of the samples (with XRF, XRD, mineralogical analyzes), gravity and magnetic separation tests were carried out. Quartz and hematite are the main minerals of micaceous hematite ores. Silica grade as the major impurity varies from 10% to 68%. The total iron content of the samples also varies from 15% to 62%. A jig and shaking table did not provide a good result in micaceous hematite beneficiation to achieve the standard of its specific applications. Gravity concentration by the spiral in the size range of -200 and -300 μm has led to the production of iron concentrates with a grade of 62.34% and 64.84%, respectively. The recovery values for the two experiments are 13.50% and 12.60%, respectively. Therefore, the spiral did not provide a good result in the micaceous iron ore beneficiation. High-intensity magnetic separation (1.2 T) has resulted in a product with a grade and recovery of 65.98% and 88.35%, respectively. The experimental design utilizing the Taguchi method considering the increasing of grade or recovery priority indicated that for micaceous iron beneficiation with a priority of recovery increasing, the feeder frequency, roll speed, and adjustable gate angle should be at 6.5 Hz, 95 rpm, and 20°, respectively. However, for micaceous iron beneficiation with a priority of grade increasing, the feeder frequency, roll speed, and adjustable gate angle should be at 2.5 Hz, 135 rpm, and 60°, respectively.Svrha je ovoga istraživanja odrediti prikladnu metodu za oplemenjivanje liskunaste željezne rude te izrada standarda primjenjivih u industriji. Nakon utvrđivanja karakteristika uzoraka (s XRF, XRD, mineraloškim analizama) provedena su ispitivanja gravitacijskom i magnetskom separacijom. Kvarc i hematit glavni su minerali liskunastih hematitnih ruda. Udio silicija kao glavne nečistoće varira od 10 % do 68 %. Ukupni sadržaj željeza u uzorcima također varira od 15 % do 62 %. Plakalica i koncentracijski stol nisu dali dobre rezultate u obogaćivanju liskunastoga hematita za postizanje standar-da njegove specifične primjene. No, gravitacijska koncentracija spiralom veličine zrna -200 i -300 μm rezultirala je kvali-tetom koncentrata željeza od 62,34 odnosno 64,84 %. Vrijednosti iskorištenja bile su 13,50 odnosno 12,60 %. Stoga ni spirala nije dala dobar rezultat u obogaćivanju liskunaste željezne rude. Visokointenzivna magnetska separacija (1,2 T) rezultirala je kvalitetom koncentrata od 65,98 % i iskorištenjem od 88,35 %. Eksperimentalni dizajn prema Taguchiju s obzirom na povećanje kvalitete ili iskorištenja pokazao je da za povećanje iskorištenja frekvencija dodavača, brzina bub-nja i kut separacijskoga noža trebaju biti na 6,5 Hz, 95 o/min i 20°. Međutim, za obogaćivanje liskunaste željezne rude s prioritetom povećanja kvalitete koncentrata frekvencija dodavača, brzina bubnja i kut separacijskoga noža trebaju biti 2,5 Hz, 135 o/min, odnosno 60°
