Nitrogen Phosphorus

Runoff from typical urban and suburban landscapes may contain significant levels of nitrogen, phosphorus, and a broad spectrum of various pesticides (mainly herbicides and insecticides) due to excessive application rates of these chemicals and high irrigation requirements of most commonly used landscape plant species. Preliminary water quality data (runoff) from a comparative study of 20 microwatersheds using 4 different levels of maintenance, show reductions in these types of pollutants in runoff for microwatersheds planted to resource efficient plants. Utilization of plants indigenous to an ecoregion (and other resource efficient plants) in landscape design and management allows considerable reduction in inputs from fertilizer, water, and pesticides. This results in lower pollutant concentrations in runoff and is estimated to result in lower total pollutant loadings from such systems. Installation of native or resource efficient plants in new developments (commercial and residential) and replacement of existing landscapes with these plants as older plants die or neighborhoods are updated could provide cities and suburban areas with a cost-effective, low-maintenance, and aesthetically-pleasing pollution control technology. Data from the comparative study should provide municipalities charged with meeting the new requirements of the National Pollutant Elimination Discharge System with a way to compare the pollution prevention effectiveness of resource-efficient landscapes with more traditional structural urban runoff controls.

Halloysite/metal nanocomposites have been synthesized through the immobilization of preformed and in situ synthesized metal nanoparticles over halloysite surfaces, which in turn produce efficient, cost-effective, and environmentally benign heterogeneous catalysts.

A COMPARATIVE STUDY OF EFFICACY, POTENCY AND RECOVERY OF INTRATHECAL 0.5% ROPIVACAINE WITH FENTANYLAND 0.5% LEVOBUPIVACAINE WITH FENTANYL IN LOWER ABDOMINAL SURGERIES IN PATIENTS OF 18-60YEARS OF AGE

Care Surgery

INTRODUCTION:The recent trend in health care centres everywhere is to provide cost effective care to the patients. There is an increasing trend towards ambulatory day care surgery and rapid discharge of the patients. The operation of inguinal hernia or incisional hernia and even simple ligation surgeries are done without much complexities nowadays and can be completed in 60-90min without much intra or postoperative complications. Hence these have become an ideal procedure for outpatient setting and thereby reducing length of hospital stay. AIMS AND OBJECTIVE:A comparative study of efcacy, potency and recovery of intrathecal 0.5% ropivacaine with fentanyl and 0.5% levobupivacaine with fentanyl in lower abdominal surgeries in patients of 18-60years of age. MATERIALS AND METHOD: This is a prospective, comparative, observational study was conducted on 60 patients undergoing various lower abdominal surgeries under subarachnoid block (SAB) at Nil Ratan Sircar Medical College and Hospital, Kolkata, West Bengal. This study was conducted over a period of 24-month. Approval of the Institutional Ethics Committee was taken. Awritten informed consent in the local language was taken from every patient. RESULT AND ANALYSIS: In RF 5 patients (17%) had onset at 3min, 17patients (57%) at 6min, 7 patients (23%) at 9min, 1 patient (3%) at 12min. In LBF 8 patients had onset at 0 min, 22 patients had onset at 3min. p value is less than 0.0001 which is statistically signicant. In RF, 23 patients (77%) had duration of motor block for 150min and 7 patients (23%) had for 180min. In LBF, 26 patients (87%) had duration of motor block for 210 min and 4 patients (13%) had for 180min. The p value is less than 0.0001, which is statistically signicant. SUMMARYAND CONCLUSION: This study was to compare potency, efcacy and recovery between the two groups of drugs. A potency of a drug is a measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. Here both the drugs in comparison was given in equal concentration and found that levobupivacaine produced higher effect, reached Bromage 3 in lesser time than ropivacaine. So levobupivacaine was more potent drug. Efcacy is the ability to get a job done satisfactorily

Web Based Education

Examined and compared in this chapter is the diffusion of WBE in Singapore and Australia. These two countries were chosen in this study because of the close educational collaborations and developments between them. A number of Australian universities have offshore bases in Singapore. It would be more cost-effective and profitable to use WBE instead of using the usual corresponding method, or flying professors into the country a few times a year for intensive residential studies. In this chapter, WBE at some selected institutions is reported in detail, because these institutions represent the more advanced developments of WBE in the respective country. Meta-analysis, using a modified Taylor’s model (Taylor, 2001), reveals that though Singapore and Australia are different in their approach and policies to education and technology, they share similar trends and achievements in the development of WBE. Tertiary institutions in both countries have generally achieved all the characteristics of Generations 4 and 5 of the development model of Distance Education, as described by Taylor. However, this is not to say that face-to-face teaching has been phased out. This study also indicates that WBE supports the development of distance education and e-universities in Australia. On the other hand, it is hard to say when Singapore will develop its first e-university.
