The objective of the study was to assess student teachers' efficacy in one of the teacher training institutions in Malaysia, with specific reference to the aspects of student engagement, instructional strategies and classroom management. The sample size was 675 final-year teacher education students. The findings suggest that a majority of the respondents had a high level of teaching efficacy (M = 3.98; SD = 0.36). They were also highly efficacious in student engagement (M = 4.01; SD = 0. 41), instructional strategies (M = 4.01; SD = 0. 39) and classroom management (M = 4.00; SD = 0.45). A significant correlation was found between teaching efficacy and academic achievement C (r = 0.15, p<0.05). The study also revealed that teaching efficacy differed as a function of gender (t = 6.47, p<0.05), career choice (t = 6.04, p<0.05), educational aspiration (t = 2.02, p<0.05) and content major (F 3,668 = 9.86, p<0.05).
Fruits contain a broad spectrum of nutrients, and many of which have antioxidant properties. Phenolic substances, vitamin A, vitamin C and minerals that are present in fruits displayed high antioxidant activity. Thes properties have been associated with the decreased risk of certain degenerative diseases. This study was conducted to determine the effects of guava (Psidium guajava) consumption on total antioxidant status and lipid profile (total cholesterol, triglycerides, LDLcholesterol and HDL-cholesterol) in normal male youth. This study was carried out over nine weeks, which was divided into three phases, that is, baseline (one week), treatment (four weeks) and control (four weeks). Blood samples were collected at the end of each phase for biochemical test. Total antioxidant status, glucose, lipid profile and antioxidant enzymes (glutathione peroxidase and glutathione reductase) were determined using Cobas Mira auto analyzer (Roche). Dietary intake in each phase was studied using 24-hours diet recall. There was a significant increase of total cholesterol, triglyceride and HDL-cholesterol during the treatment phase, compared to the baseline and control phases (p < 0.05). The increase of HDL-cholesterol was associated with the decreased risk of heart attack and cardiovascular disease. Although there was an increase in total cholesterol and triglyceride in the treatment phase compared to baseline and control phases, the increase was still in normal range. There was a significant increase of total antioxidants during the treatment phase, compared to the baseline and control phases (p < 0.05). There were trends of reduction for both glutathione peroxidase and glutathione reductase in the treatment phase as compared to baseline and control phases. However, the reduction was not statistically significant. The reduction of antioxidant enzymes was associated with decreased oxidative stress and decrease in free radical activities. The consumption of guava, therefore, could result in improved antioxidant status and lipid profile. Thus, it could reduce the risk of disease caused by free radical activities and high cholesterol in blood.
Food product authentication is important at every level of the food manufacturing process, starting from raw materials until finished products. Authentication also plays an important role in assuring accurate food labelling, which is required to help consumers select suitable types of food products. Food adulteration is one of the vital issues addressed by halal authentication, especially for food products that contain pig traces or porcine ingredients. Various methods that aim to guarantee the authenticity of foods have been developed over the past years. In this article, a short review of recent food analytical methods related to authenticity studies, with special regard to pork identification, is provided. The focus of this review is DNA-based methods, which have gained the interest of the scientific community. The specificity, sensitivity and fast and high throughput of the methods are highlighted. In the present case, methods that are capable of detecting pork by using DNA barcode, polymerase chain reaction (PCR)-restriction fragment length polymorphism, conventional PCR, real-time PCR and isothermal amplification are discussed. Although PCR is the most popular method, recent studies have shown that isothermal amplification is a potential alternative because it is rapid, simple and does not require the use of any complicated instruments, such as a thermal cycler and sequencer.
Zinc oxide nanorods were grown on Si (100) and Platinum coated glass substrate by the aqueous chemical growth (ACG) in aqueous solution that contained zinc nitrate hexahydrate (Zn(NO3)2•6H20) and hexamethylenetetramine (C6H12N4). The obtained ZnO nanorods are uniformly distributed on the Platinum coated glass substrate surface from 1.5 h to 3 h growth time. Branched hexagonal rods were also found growth on these uniform nanorods. Branched hexagonal rods were found on Si (100) from 2 h to 3 h growth time. A small number of flower-like structures compared to the majority oval type structure suggest that secondary nucleation had occurred during the process of growth. All of the high intensity peaks, including the strong (101) peak, are assigned to wurtzite ZnO hexagonal indicating that the product is pure ZnO. The results found in this study revealed that the type substrate plays a role in determining the surface morphology of ZnO growth.
Medicinal cupping is one of the traditional treatment methods that is trusted to give many benefits to the human health and still practising by various culture and societies around the world. The purposes of this treatment are to allow the toxin leaves the body,to stimulate the muscles and also helping in healing process for various diseases. The process start by placing special heated cups on specific points to create suction, then the points will be punctured. Each disease has specific cupping points to be cupped which located on the human nerves system. All the points actually connected to each other where a simple graph can be formed. Since there are limited studies that discuss medicinal cupping in a mathematics view, thus this research is conducted to introduce the easiest way on demonstrating the cupping points on the human nerves system by using the idea of graph. Hence, new definition of nerve vertex, nerve edge and nerve graph will be defined. Moreover, the idea of graph colouring will be applied to determine the optimal number of cupping points.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
