Prey Predator Fishery Model with Stage Structure in Two Patchy Marine Aquatic Environment

引用

Applied Mathematics 2011年第11期2卷 1405-1416页

作者： Mellachervu Naga Srinivas Mantripragada Ananata Satya Srinivas Kalyan Das Nurul Huda gazi 不详

In this paper, we propose and analyze a mathematical model to study the dynamics of a fishery resource system with stage structure in an aquatic environment that consists of two zones namely unreserved zone (fishing permitted) and reserved zone (fishing is strictly prohibited). In this model we introduce a stage structure in which predators are split into two kinds as immature predators and mature predators. It is assumed that immature predators cannot catch the prey and their foods are given by their parents (mature predators). It is also assumed that the fishing of immature predators prohibited in the unreserved zone and predator species are not allowed to enter inside the reserved zone. The local and global stability analysis has been specified. Biological and Bionomical equilibriums of the system are derived. Mathematical formulation of the optimal harvesting policy is given and its solution is derived in the equilibrium case by using Pontryagin’s maximum principle.

Community’s Perspectives towards Marine Protected Area in Perhentian Marine Park, Malaysia

引用

Open Journal of Marine Science 2014年第2期4卷 51-60页

作者： gazi Md. Nurul Islam Tai Shzee Yew Kusairi Mohd Noh Aswani Farhana Mohd Noh Faculty of Economics and Management Universiti Putra Malaysia Serdang Malaysia Institute of Agricultural and Food Policy Studies Universiti Putra Malaysia Serdang Malaysia

The Perhentian Islands located in the East coast of Peninsular Malaysia. They are well-known for their rich coral reef ecosystems. Marine resources of Malaysia have been overexploited in general due to overfishing and other development activities. Such no-take marine protected areas (MPAs) were established in Malaysia including Perhentian Islands Marine Park to enable overexploited marine resources to recover and to conserve coral reef ecosystems. This paper examines the current level of activities causing damages to the coral reef habitats in the Perhentian MPA. This study used paired comparison method to elicit the perception of the local stakeholders on the activities harmful to the marine habitats. The results of the analysis showed that various respondent groups had similar preference rankings on the harmful activities: littering, discarding fishing equipments, excess fishing and too many divers that cause damage to the habitats in the MPA area. The findings suggest that policy makers should take cognizance of the local stakeholders’ concern in planning and designing of marine protected areas in Malaysia.

Predictive Factors of Hyponatremia in Under-Five Severely Malnourished Children with Pneumonia Admitted to a Large Urban Hospital in Dhaka, Bangladesh: A Nested Case-Control Design

引用

Food and Nutrition Sciences 2013年第4期4卷 398-404页

作者： Cheryl Kay Zogg Tahmeed Ahmed Abu Syeed Golam Faruque Sumon Kumar Das gazi Imran Mohammod Jobayer Chisti Centre for Nutrition & Food Security (CNFS) International Centre for Diarrhoeal Disease Research Bangladesh (icddrb) Dhaka Bangladesh Dhaka Shishu Hospital Dhaka Bangladesh Johns Hopkins Bloomberg School of Public Health Baltimore USA

Background: Hyponatremia is the most common electrolyte imbalance encountered in the management of diarrheal children. Common ramifications include cerebral edema and fatal outcomes. However, pediatric data remain lacking, particularly in developmental contexts where resources are limited and associated conditions like malnutrition and pneumonia are common. Aim: This study aimed to evaluate predicting factors associated with hyponatremia in children under five years of age with severe acute malnutrition (SAM) in Bangladesh. Methods: Using a nested case-control design, we compared clinical and laboratory characteristics of children with (n = 61) and without hyponatremia (n = 183) taken from a parent population of all children under five with SAM and clinical or radiological pneumonia admitted to Dhaka Hospital of icddr,b between April 2011 and June 2012 (n = 407). Results: Logistic regression analysis adjusting for potential confounders such as lack of breast feeding, duration of vomiting (days), and severe wasting revealed that older age (OR 1.05, 95%CI 1.02 - 1.07, p = 0.001) (5% increase in the relative odds of hyponatremia for each additional month of age), presence of diarrhea (OR 2.43, 95%CI 1.0 - 6.0, p = 0.05), and difficulty breathing (OR 1.52, 95%CI 1.0 - 2.05, p = 0.05) were significantly associated with hyponatremia. Conclusion: Our data suggest that older age, presence of diarrhea, and difficulty breathing in under-five children with SAM is independent predictors of hyponatremia. These findings underscore the importance of detecting simple clinical predictors early in order to facilitate appropriate management and to prevent potential ramifications of hyponatremia in SAM children, especially in resource-poor settings.

Geochemistry of Neogene Mudrocks from Sitakund Anticline, Bengal Basin: Implications for Provenance, Weathering, Tectonic Setting and Depositional Environment

引用

Journal of Geoscience and Environment Protection 2017年第6期5卷 147-171页

作者： Md. Yousuf gazi S. M. Mainul Kabir Md. Badrul Imam Aminur Rahman Md. Ashraful Islam Department of Geology University of Dhaka Dhaka Bangladesh Institute of Mining Mineralogy and Metallurgy Joypurhat Bangladesh

Geochemical analysis of Neogene mudrocks from Sitakund anticline, Chittagong Tripura Fold Belt (CTFB), Bengal Basin, Bangladesh, was deployed to delineate the provenance, tectonics and depositional environments. Representative samples went through mineralogical and geochemical analysis concerning major, trace and rare earth element analysis. Rigaku ZSX Primus and NITON XL3t 800 XRF instruments were utilized for the determination of major and trace elements. The experiment results reveal that the Neogene mudrocks are rich in silica having concentration of 58.10% to 62.60% with an average of 59.90%. Therefore, the geochemical response from the experiments apparently proved the existence of the active continental margin setting for the Neogene mudrocks. Different concentrations and ratios of major oxides satisfy that the mudrocks were derived from felsic source rocks. In addition, chemical index of alteration (CIA) values for the Neogene mudrocks vary from 67.81 to 77.57 with an average 74.41 indicating significant weathering at the source areas. Moreover, U/Th, Cu/Zn, Ni/Co and V/Cr ratios designate that the mudrocks were deposited in oxidizing depositional environment.

Utilization of Open Source Spatial Data for Landslide Susceptibility Mapping at Chittagong District of Bangladesh—An Appraisal for Disaster Risk Reduction and Mitigation Approach

引用

International Journal of Geosciences 2017年第4期8卷 577-598页

作者： Md. Ashraful Islam Sanzida Murshed S. M. Mainul Kabir Atikul Haque Farazi Md. Yousuf gazi Israt Jahan Syed Humayun Akhter Department of Geology University of Dhaka Dhaka Bangladesh Department of Geology and Mining University of Barisal Barisal Bangladesh

Since creation of spatial data is a costly and time consuming process, researchers, in this domain, in most of the cases rely on open source spatial attributes for their specific purpose. Likewise, the present research aims at mapping landslide susceptibility at the metropolitan area of Chittagong district of Bangladesh utilizing obtainable open source spatial data from various web portals. In this regard, we targeted a study region where rainfall induced landslides reportedly causes causalities as well as property damage each year. In this study, however, we employed multi-criteria evaluation (MCE) technique i.e., heuristic, a knowledge driven approach based on expert opinions from various discipline for landslide susceptibility mapping combining nine causative factors—geomorphology, geology, land use/land cover (LULC), slope, aspect, plan curvature, drainage distance, relative relief and vegetation in geographic information system (GIS) environment. The final susceptibility map was devised into five hazard classes viz., very low, low, moderate, high, and very high, representing 22 km2 (13%), 90 km2 (53%);24 km2 (15%);22 km2 (13%) and 10 km2 (6%) areas respectively. This particular study might be beneficial to the local authorities and other stake-holders, concerned in disaster risk reduction and mitigation activities. Moreover this study can also be advantageous for risk sensitive land use planning in the study area.
