Surveillance of drinking water is essentially a health measure intended to protect the public from water borne diseases. Hydride
generator accessory coupled with atomic absorption spectrophotometer was used to analyze arsenic level in 49 ground water
samples collected from different areas of Delhi. Arsenic level in ground water samples was in the range of 0.0170 to 0.100
ppm (Mean-0.0431, Standard Deviation-0.0136, Std. error of Mean-0.00194) with minimum concentration at Raney Well No. 7 (0.0170
ppm) and maximum at Kotla Mubarak Pur (0.100 ppm). Arsenic containing sediments and percolation of chemicals into soil as
the result of dumping of garbage rich in chemicals into open landfills could be the possible source of arsenic in ground water
of Delhi. Extensive survey and continuous monitoring is required to be made to assess the magnitude of problem and earlier
intervention. 相似文献

In recent years, countries of the Pacific have been moving strongly towards enhancing inclusive educational practices within a previously segregated education system. Through the Pacific Education Development Framework (PEDF) approved by 14 Pacific Island Education Ministers in 2009, the implementation of regional policies of inclusive education is a priority. To ensure that progress is measurable, these countries have been working collaboratively with several Australian institutions to develop a set of contextually appropriate indicators for measuring disability-inclusive education. This article describes the process adopted in developing these indicators and initial findings regarding the key outcomes. The research is guided by three key principles of collaboration, a need for systemic change and ‘nothing about us without us’. The process adopts a three-stage approach which is outlined and key issues and implications discussed. 相似文献

ABSTRACTCountries of the Pacific region are currently undergoing significant reforms. While disability inclusive education has been identified as a regional priority by all member nations, implementing inclusive education in the countries of the region can be quite challenging as many barriers continue to hamper the progress of the countries. Unless the barriers are identified and systematically addressed, it is unlikely that the countries will be able to implement a robust and holistic inclusive education strategy. In this paper, we present possible ways in which the countries of the Pacific could make significant progress in implementing a sustainable inclusive education strategy. We used a collaborative approach of co-examining potential barriers that are likely to impede the growth of countries in implementing a comprehensive inclusive education plan of action. We then identified possible strategies that are likely to result in an improved and perhaps more culturally responsive implementation of inclusive education in the Pacific. The most significant barriers identified by the members included: inadequate teacher preparation, stigma and negative attitudes towards people with disabilities, and limited engagement with the local leaders and key stakeholders. Possible strategies for addressing the barriers are outlined and discussed with possible implications for local, regional, and international researchers and policy makers. 相似文献

Open educational resources (OER) are digitised material freely available to the students and self learners. Many institutions had initiated in incorporating these OERs in their higher educational system, to improve the quality of teaching and learning. These resources promotes individualised study, collaborative learning. If they are coupled with Learning Objects of Learning Management System (LMS), they can lead to opportunities for further pedagogical innovation. It has become increasingly important for educational institutions to support these resources, in a planned and systematic manner. Adapt, assemble and conceptualise existing OERs to respond to diverse learning needs of students and support a variety of learning approaches for a given learning goal is a challenge. In this work, convergence of OERs with Learning Objects is done through metadata using classification techniques. Localisation of these high quality learning materials with the learning content of LMS, delivered as a single instructional unit may help in greater knowledge delivery and this can satisfy the learning needs of diverse student. 相似文献

This paper reports perceived barriers and facilitators of disability‐inclusive education, and outcomes of an effective system of inclusive education in the Solomon Islands. Data were gathered from a variety of stakeholder group participants (n = 10) and individual key informants (n = 2), ranging from parents of children with disabilities to government representatives. The results revealed a unique perspective on disability‐inclusive education in this context, and provided insight into possible directions towards a more inclusive system. 相似文献

Serum vitamin E and cholesterol concentrations were measured in 50 children with protein energy malnutrition (PEM) and results
were compared with a group of 50 normal controls. Mean serum vitamin E concentration as well as vitamin E/cholesterol ratio
were found to be reduced in children with PEM while their mean serum cholesterol level was not significantly different from
the control group. Data suggest that the reduced levels of serum vitamin E in PEM may be a result of malnutrition per se. 相似文献

Lotka's law and institutional productivity 总被引:1,自引:0,他引:1
The present study aims at determining the applicability of Lotka's law, negative binomial distribution and lognormal distribution for institutional productivity, in the same way as it is to authors and their productivity in the field of engineering sciences and the patents filed by industrial firms in laser S&T. The study indicates that non of the three distributions are applicable for institutional productivity in engineering sciences. However, Lotka's law holds good for full as well as truncated set of data for the patents filed by industrial firms. 相似文献

The antioxidants are essential molecules in human system but are not miracle molecules. They are neither performance enhancers
nor can prevent or cure diseases when taken in excess. Their supplemental value is debateable. In fact, many high quality
clinical trials on antioxidant supplement have shown no effect or adverse outcomes ranging from morbidity to all cause mortality.
Several Chochrane Meta-analysis and Markov Model techniques, which are presently best available statistical models to derive
conclusive answers for comparing large number of trials, support these claims. Nevertheless none of these statistical techniques
are flawless. Hence, more efforts are needed to develop perfect statistical model to analyze the pooled data and further double
blind, placebo controlled interventional clinical trials, which are gold standard, should be implicitly conducted to get explicit
answers. Superoxide dismutase (SOD), glutathione peroxidase and catalase are termed as primary antioxidants as these scavenge
superoxide anion and hydrogen peroxide. All these three enzymes are inducible enzymes, thereby inherently meaning that body
increases or decreases their activity as per requirement. Hence there is no need to attempt to manipulate their activity nor
have such efforts been clinically useful. SOD administration has been tried in some conditions especially in cancer and myocardial
infarction but has largely failed, probably because SOD is a large molecule and can not cross cell membrane. The dietary antioxidants,
including nutrient antioxidants are chain breaking antioxidants and in tandem with enzyme antioxidants temper the reactive
oxygen species (ROS) and reactive nitrogen species (RNS) within physiological limits. Since body is able to regulate its own
requirements of enzyme antioxidants, the diet must provide adequate quantity of non-enzymic antioxidants to meet the normal
requirements and provide protection in exigent condition. So far, there is no evidence that human tissues ever experience
the torrent of reactive species and that in chronic conditions with mildly enhanced generation of reactive species, the body
can meet them squarely if antioxidants defense system in tissues is biochemically optimized. We are not yet certain about
optimal levels of antioxidants in tissues. Two ways have been used to assess them: first by dietary intake and second by measuring
plasma levels. Lately determination of plasma/serum level of antioxidants is considered better index for diagnostic and prognostic
purposes. The recommended levels for vitamin A, E and C and beta carotene are 2.2–2.8 μmol/l; 27.5–30 μmol/l; 40–50 μmol/l
and 0.4–0.5 μmol/l, respectively. The requirement and recommended blood levels of other dietary antioxidants are not established.
The resolved issues are (1) essential to scavenge excess of radical species (2) participants in redox homeostasis (3) selective
antioxidants activity against radical species (4) there is no universal antioxidant and 5) therapeutic value in case of deficiency.
The overarching issues are (1) therapeutic value as adjuvant therapy in management of diseases (2) supplemental value in developing
population (3) selective interactivity of antioxidant in different tissues and on different substrates (4) quantitative contribution
in redox balance (5) mechanisms of adverse action on excess supplementation (6) advantages and disadvantages of prooxidant
behavior of antioxidants (7) behavior in cohorts with polymorphic differences (8) interaction and intervention in radiotherapy,
diabetes and diabetic complications and cardiovascular diseases (9) preventive behavior in neurological disorders (10) benefits
of non-nutrient dietary antioxidants (11) markers to assess optimized antioxidants status (12) assessment of benefits of supplementation
in alcoholics and heavy smokers. The unresolved and intriguing issues are (1) many compounds such as vitamin A and many others
possessing both antioxidant and non-antioxidant properties contribute to both the activities in vivo or exclusively only to
non-antioxidant activity and (2) since human tissues do not experience the surge of FR, whether there is any need to develop
stronger synthetic antioxidants. Theoretically such antioxidants may do more harm than good. 相似文献

This study deals with the effects of freeze dried rhizome powder of Curcuma longa (C. longa) dissolved in milk on normal as
well as diabetic models. Diabetes of type II and type I was within 3 days of a single administration of doses of 45 and 65
mg kg−1 of streptozotocin respectively. Various parameters such as blood glucose levels, triglycerides, total cholesterol, high density
lipoprotein, very low density lipoprotein, low density lipoprotein, serum glutamic oxaloacetic transaminase, serum glutamic
pyruvate transaminase, alkaline phosphatase, creatinine, hemoglobin, urine protein and urine sugar in addition to body weight
were taken in to consideration and were analyzed after administration of variable doses of rhizome powder. The dose of 200
mg kg−1 was identified as the most effective dose as it increased HDL, Hb and bw (P<0.05) with significant decrease in the levels
of blood glucose, lipid profile and hepatoprotective enzymes (P<0.001). 相似文献
