Md. Fazlul Islam,S.M. Rezaul Karim,S.M.A. Haque,Md. Sirajul Islam
Journal of Agronomy , 2003,
Abstract: A pot experiment was conducted to study the effect of Echinochloa crusgalli and Echinochloa colonum on the growth and yield of rice (cv. IR50) during April to July 2002. The results showed that the effect of two weeds pot G 1 produced 70.6% yield loss of rice grain and about 97% grain yield was reduced when 8 weeds competed against a single rice plant. The reduction of rice grain at this density was the results of 42.9% reduction of plant height, 92% reduction of LAI, 72.7% reduction of tillers plant G 1, 88.5% reduction of panicles/plant and 63.8% reduction of grains panicle G 1. Further increase of weed density produced the self-thinning effect of weeds and rice yield increased in comparison to 8 weeds pot G1. It was concluded that Echinochloa crusgalli and E. colonum produced similar effects on grain yield and other plant characteristics of rice.
RBFs Meshless Method of Lines for the Numerical Solution of Time-Dependent Nonlinear Coupled Partial Differential Equations  [PDF]
Sirajul Haq, Arshad Hussain, Marjan Uddin
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.24051
Abstract: In this paper a meshless method of lines is proposed for the numerical solution of time-dependent nonlinear coupled partial differential equations. Contrary to mesh oriented methods of lines using the finite-difference and finite element methods to approximate spatial derivatives, this new technique does not require a mesh in the problem domain, and a set of scattered nodes provided by initial data is required for the solution of the problem using some radial basis functions. Accuracy of the method is assessed in terms of the error norms L2, L∞ and the three invariants C1, C2, C3. Numerical experiments are performed to demonstrate the accuracy and easy implementation of this method for the three classes of time-dependent nonlinear coupled partial differential equations.
Pollution in the Bay of Bengal: Impact on Marine Ecosystem  [PDF]
Towhida Rashid, Sirajul Hoque, Sharmin Akter
Open Journal of Marine Science (OJMS) , 2015, DOI: 10.4236/ojms.2015.51006
Abstract: The study focused on heavy metal concentration in sea water, sea sediment and their toxic effect on sea shells, and on oyster along the east coast of the Bay of Bengal. The hierarchy of heavy metals in sea sediment of the bay showed as: Fe > Zn > Ni > Cr > Pb > Cd. The average concentration of nickel exceeded ERL (20.9 μg·g-1) value and the incidence of adverse effects on biological components exceeded 16.7%. The present study showed that the concentration of Cd, Fe, Pb and Cu in sea water were relatively higher than the standard concentration. The study showed a considerable amount of heavy metals (0.035%) such as Zn, Pb, Cu, Fe, and Mg in sea shells, and oyster which may make them toxic. The toxic effect of Pb and Zn may reduce their growth which is a great threat to marine ecosystem.
Application of a Numerical Method Using Radial Basis Functions to Nonlinear Partial Differential Equations
Marjan Uddin,Sirajul Haq
Sel?uk Journal of Applied Mathematics , 2011,
Abstract: In this paper, we propose a meshfree method for numerical solution of various classes of partial differential equations (PDEs), such as the Boussinesq system, Drinefel'd-Sokolov-Wilson equations, and Hirota-Satsuma coupled KdV system. The meshfree algorithm is based on scattered data interpolation along with approximating functions known as radial basis functions (RBFs). The meshfree technique does not require space discretization. A set of scattered nodes provided by initial data is used for solution of the problem. Accuracy of the method is estimated in terms of the error norms L , L_{∞}, number of nodes in the domain of influence, time step size, parameter dependent and parameter independent RBFs, the numerical validation for the above mentioned three types of PDEs is given to check performance of the new approach.
Status of water quality in the Dhaleshwari River and its effect on aquatic organism
Sirajul Islam,Mahmudul Islam
Journal of Environmental Science and Water Resources , 2012,
Abstract: The study was conducted to know the status of water quality in the Dhaleshwari river and its temporal changes over monsoon, post-monsoon and pre-monsoon seasons due to change of physicochemical parameters during the period from June 2011 to May 2012. The river starts off the Jamuna near the north-western tip of Tangail district with high potential for sheries production in this area. Over exploitation of fisheries resources, river bank erosion and human activities are gradually hampered the aquatic environment of the river. For existence and conservation of aquatic resources, it is essential to investigate the water quality and surrounding environment of the river. The results of the study showed that the concentrations of EC (Electric conductivity), DO (Dissolved oxygen), BOD (Biological oxygen demand), Hardness, Sodium, Potassium and Copper were within the standard limit as well as suitable for aquatic lives. The water pH was less than the standard i.e. slightly acidic, transparency was incalculable and TDS (Total dissolved solid) was increased in both post and pre-monsoon seasons. The content of Total Nitrogen, Phosphorus and Cadmium exceeded the permissible limit in all seasons. The excessive abundance of Total Nitrogen and Phosphorus made the river prone to eutrophication which ultimately resulted into degradation of water quality, phytoplankton blooms and change in fish production. This could be due to excessive agricultural activities near and adjacent to the bank of the river. The comparative study showed that most of the water quality parameters of the Dhaleshwari river were suitable for aquaculture of aquatic organisms as well as fishes.

Farhana Haque, Subodh Kumar Kundu, Md Saiful Islam, S. M. Murshid Hasan, Asma Khatun, Partha Sarathi Gope, Zahid Hayat Mahmud, A. S. M. Alamgir, M. Sirajul Islam, Mahmudur Rahman, Stephen P. Luby
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0080420
Abstract: Background In 2010, an acute illness outbreak was reported in school students eating high-energy biscuits supplied by the school feeding programme in northwest Bangladesh. We investigated this outbreak to describe the illness in terms of person, place and time, develop the timeline of events, and determine the cause and community perceptions regarding the outbreak. Methods We defined case-patients as students from affected schools reporting any two symptoms including abdominal pain, heartburn, bitter taste, and headache after eating biscuits on the day of illness. We conducted in-depth interviews and group discussions with students, teachers, parents and community members to explore symptoms, exposures, and community perceptions. We conducted a questionnaire survey among case-patients to determine the symptoms and ascertain food items eaten 12 hours before illness onset, and microbiological and environmental investigations. Results Among 142 students seeking hospital care, 44 students from four schools qualified as case-patients. Of these, we surveyed 30 who had a mean age of 9 years; 70% (21/30) were females. Predominant symptoms included abdominal pain (93%), heartburn (90%), and bitter taste (57%). All students recovered within a few hours. No pathogenic Vibrio cholerae, Shigella or Salmonella spp. were isolated from collected stool samples. We found no rancid biscuits in schools and storage sites. The female index case perceived the unusually darker packet label as a “devil’s deed” that made the biscuits poisonous. Many students, parents and community members reported concerns about rumors of students dying from biscuit poisoning. Conclusions Rapid onset, followed by rapid recovery of symptoms; female preponderance; inconsistent physical, microbiological and environmental findings suggested mass sociogenic illness rather than a foodborne or toxic cause. Rumours of student deaths heightening community anxiety apparently propagated this outbreak. Sharing investigation results and reassuring students and parents through health communication campaigns could limit similar future outbreaks and help retain beneficiaries’ trust on nutrition supplementation initiatives.
