Communities in conservation: Protected area management and enhanced conservation in Bangladesh
In the last few decades, the natural resource base of most developing countries has decreased alarmingly because of enormous population pressure and extreme poverty. Bangladesh is no exception, having lost most of its forest in the last 30 years. The Government of Bangladesh (GoB) has adopted various approaches to conserve the country’s remaining biodiversity, including protected areas (PAs). However, the creation of PAs alone has not produced positive conservation results as expected, due to a purely ecological focus that excluded the needs of local forestdependent people. The introduction of community-based natural resource management (CBNRM) for nature conservation in PAs is relatively new for Bangladesh compared to other South Asian countries, but it seems to have effected significant changes. The GoB recently adopted CBNRM in five of its PAs as part of a pilot programme in collaborative management. This paper is a case study of the changing trends in PA management, people’s livelihoods and attitudes in and around one of these pilot sites. We observed that some changes have already taken place in forest resource collection patterns and in the attitudes of people in the locality. People’s income sources and dependency on protected forests have also noticeably shifted away from forest areas in the Communities in conservation: protected area management and enhanced conservation in Bangladesh last year. Although gradual, people’s participation seems to be changing the direction of future forest conservation in Bangladesh. We conclude that bringing a larger number of people under various income-generating schemes, clearly defining the rights and responsibilities of the local people in PAs and ensuring more effective governance should be the next steps for the future of participatory management in the country
USCID fourth international conference
Presented at the Role of irrigation and drainage in a sustainable future: USCID fourth international conference on irrigation and drainage on October 3-6, 2007 in Sacramento, California.Includes bibliographical references.As a lower riparian country Bangladesh is largely dependent on 57 transboundary rivers. The upstream courses of these river systems traverse India, China, Nepal, Bhutan and Myanmar. Each day, approximately 3,000 million cubic meters of water discharge into the Bay of Bengal through these rivers. However, flows are much lower during the dry season when surface water is critical to such uses as irrigation, salinity control, habitat preservation, effluent dilution and navigation. Unilateral diversion of water from the transboundary rivers impedes agricultural development using irrigation-fertilizers-modern varieties technology. Thus, sustainable irrigation system is instrumental for the growth of food production. For this, peoples' participation is prerequisite to form social capital in building consensus about the irrigation water uses. Local Government Engineering Department (LGED) has developed a model to facilitate sustainable use of water resources and demonstrated its effectiveness for irrigation management. It develops stakeholders-driven water infrastructure in subprojects each covering 1,000 ha or less. LGED involves local people in subproject planning, design, construction and operation and maintenance (O&M). It has constructed 320 subprojects under the Small Scale Water Resources Development Sector Project. Case study in a subproject in northwestern part of the country found that local stakeholders' participation in managing water resources and operation of water control infrastructure results in excellent performance of irrigation system and improvement of distribution system. This raises irrigation efficiency with productive use of water and releases constraints on land use through facilitating cultivation in three crop seasons and increases the proportion of irrigated area under small farms
Comparative evaluation of the effect of Ocimum sanctum and metformin on serum lipid profile in high fat diet fed diabetic rats
Background: Dyslipidaemia is an important risk factor for development of macrovascular complications in type 2 diabetes mellitus. Ocimum sanctum (OS) and metformin have shown to have antihyperlipidaemic effects. The present study was undertaken to evaluate the effects of OS and Metformin on body weight & plasma lipid levels of high fat diet fed diabetic ratsMethods: Total of 30 male wistar rats (100-150gm) were obtained. Animals were fed with a high fat diet throughout the study (6 weeks). Diabetes was induced by using single intra-peritoneal injection of Streptozotocin 50mg/kg at the end of 4 weeks. Diabetic rats were divided into groups of 6 each and treated as follows: Group 1- Diabetic control, was given vehicle orally. Group 2- O.S. ethanolic extract 100mg/kg body weight orally for 14 days. Group 3- O.S. ethanolic extract 200mg/kg body weight orally for 14 days. Group 4- Metformin 100mg/day for 14 daysResults: At the end of 4 weeks, body weight of rats were significantly increased (p 0.05). Decrease in body weight was seen in metformin group. Abdominal circumference of rats also showed similar pattern (p >0.05). OS 200 caused significant reduction in serum LDL levels (p 0.05).Conclusions: Present study revealed that Ocimum Sanctum caused significant reduction in serum lipid levels in high fat diet fed diabetic rats. Metformin also exhibited antihyperlipidaemic activity. So, it is concluded that OS or metformin alone or in combination could be a novel adjunct to diet and life style modification for the management of dyslipidaemia in type 2 diabetes. Further studies are required to confirm the antidyslipidaemic activities of individual phytoconstituents of Ocimum sanctum
Comparative study of effects of ramosetron and ondansetron on global satisfaction of patients on cisplatin chemotherapy in head and neck cancers
Background: To compare level of satisfaction of the patients receiving ramosetron and ondansetron in prevention of acute and delayed nausea and vomiting associated with cisplatin chemotherapy.Methods: 60 patients were recruited in the study. Patients were randomly allocated to ramosetron (R) and ondansetron group (O). Patients were screened between day 1 and day 7. Study visits included clinic visits on day 8, day 9 and day 14. Patient diaries were used to record patients’ global satisfaction which was based on severity of nausea and vomiting using visual analogue scale (VAS), recorded daily until day 12 starting from day 8. On 14th day the patient diary cards were collected back.Results: VAS score was significantly lower in R group (46.2±4.95) as compared to O group (63.7±5.06) (p<0.01) in acute phase of nausea and vomiting indicating level of satisfaction higher in R group. Similarly, in delayed and overall phase R group (49.57±14.63 and 48.9±12.91 respectively) experienced lower range of scoring on VAS scale as compared to O group (63.0±8.49 and 63.10±7.38 respectively). The difference was statistically significant (p<0.01).Conclusions: Level of overall satisfaction of the patients in R group was significantly higher as compared to O group in patients receiving the two drugs for prevention of nausea and vomiting caused by cisplatin chemotherapy in head and neck cancer patients
Analysis of self medication practice among medical undergraduates: a study in tertiary care teaching hospital, Bareilly
Background: Self medication is becoming a most prevalent practice among educated people across the world. In today’s era, internet and media is one of the most important sources for promoting self medication practice. Medical students are highly influenced with this practice. Many drugs can have significant unwanted effects. This may result in serious clinical effects with potential life-threatening complications. Objective of the study was to find out the self medication practice and its details among medical undergraduates of SRMSIMS, a tertiary care teaching hospital, Bareilly.Methods: During the study period 1st, 2nd and 3rd prof. of MBBS students were included in the study. Sample size was 348. They were asked to fill printed semi structured validated questionnaire which consist of straight forward multiple type questions. The duration of study was March 22nd 2015 to 29th March 2015.Results: Out of 300 students, 60% (n=180) students were male and 40% (n=120) were females. Among them 94% (n=282) gave positive response and 6% (n=18) gave negative response to self-medication. Antibiotics were the most common class of drug self medicated by the majority of participants (80%) while the most common illness was fever (70%).Conclusions: It was concluded that more than half of strength of students are likely to take self-medication for various illnesses; the reason might be the awareness of drugs due to easy accessibility of information through books, internet pharmacy and through media too. So, essential measure should be taken to reduce the practice of self medication among students to avoid development of drug dependence, resistance and drug interactions
Self-Consistent C-V Characterization of Depletion Mode Buried Channel InGaAs/InAs Quantum Well FET Incorporating Strain Effects
We investigated Capacitance-Voltage (C-V) characteristics of the Depletion
Mode Buried Channel InGaAs/InAs Quantum Well FET by using Self-Consistent
method incorporating Quantum Mechanical (QM) effects. Though the experimental
results of C-V for enhancement type device is available in recent literature, a
complete characterization of electrostatic property of depletion type Buried
Channel Quantum Well FET (QWFET) structure is yet to be done. C-V
characteristics of the device is studied with the variation of three important
process parameters: Indium (In) composition, gate dielectric and oxide
thickness. We observed that inversion capacitance and ballistic current tend to
increase with the increase in Indium (In) content in InGaAs barrier layer.Comment: 5 pages, ICEDSA conference 201
In_xGa_{1-x}Sb MOSFET: Performance Analysis by Self Consistent CV Characterization and Direct Tunneling Gate Leakage Current
In this paper, Capacitance-Voltage (C-V) characteristics and direct tunneling
(DT) gate leakage current of antimonide based surface channel MOSFET were
investigated. Self-consistent method was applied by solving coupled
Schr\"odinger-Poisson equation taking wave function penetration and strain
effects into account. Experimental I-V and gate leakage characteristic for
p-channel InxGa1-xSb MOSFETs are available in recent literature. However, a
self- consistent simulation of C-V characterization and direct tunneling gate
leakage current is yet to be done for both n- channel and p-channel InxGa1-xSb
surface channel MOSFETs. We studied the variation of C-V characteristics and
gate leakage current with some important process parameters like oxide
thickness, channel composition, channel thickness and temperature for n-channel
MOSFET in this work. Device performance should improve as compressive strain
increases in channel. Our simulation results validate this phenomenon as
ballistic current increases and gate leakage current decreases with the
increase in compressive strain. We also compared the device performance by
replacing InxGa1-xSb with InxGa1-xAs in channel of the structure. Simulation
results show that performance is much better with this replacement.Comment: 7 pages, EIT 2012 IUPUI conferenc
Self Consistent Simulation of C-V Characterization and Ballistic Performance of Double Gate SOI Flexible-FET Incorporating QM Effects
Capacitance-Voltage (C-V) & Ballistic Current- Voltage (I-V) characteristics
of Double Gate (DG) Silicon-on- Insulator (SOI) Flexible FETs having sub 35nm
dimensions are obtained by self-consistent method using coupled Schrodinger-
Poisson solver taking into account the quantum mechanical effects. Although,
ATLAS simulations to determine current and other short channel effects in this
device have been demonstrated in recent literature, C-V & Ballistic I-V
characterizations by using self-consistent method are yet to be reported. C-V
characteristic of this device is investigated here with the variation of bottom
gate voltage. The depletion to accumulation transition point (i.e. Threshold
voltage) of the C-V curve should shift in the positive direction when the
bottom gate is negatively biased and our simulation results validate this
phenomenon. Ballistic performance of this device has also been studied with the
variation of top gate voltage.Comment: 4 pages, ICEDSA 2012 conferenc
