This paper shows the criteria of obtaining soil particle size distributions using electrical signal propagation in geotechnical investigations. Soil type identification is the most important requirements in structural engineering, geotechnical engineering, and other division of civil engineering. Generally, soil type is determined through the measurement of particle distribution of soil using sieve tests in geotechnical laboratory. Determination of soil particle size in conventional laboratory tests with sieve analysis is very tedious, slower and costly for the laboratory testing including dry sample collections. In this work, a method and criteria of soil particle size determinations with electrical resistivity is revealed to define different types of soil in the soil site investigations of geotechnical engineering. The performance of the proposed technique is verified with laboratory testing data in soil particle size investigations. The research is most significant as simpler, cost-effective testing in soil particle size identification through electrical signal for a wide range of applications in geotechnical engineering.

Disaster Prevention and Management

Purpose: This paper aims to document a case study of a disaster in Bangladesh and the role of an information management system for disaster management planning. Design/methodology/approach: The paper uses a methodology that considers perceptions or constructions - including the role of information systems - to be dependent on the social and cultural structures, which is helpful in reducing destruction in disaster-prone areas. Findings: Advances in information technology in the form of the internet, geographic information systems (GIS), remote sensing, satellite communication, etc. are beneficial in many aspects of the planning and implementation of hazard reduction arrangements. Research limitations/implications: Natural disasters strike countries, both developed and developing, cause enormous destruction and create human suffering, and have negative impacts on national economies. Bangladesh suffers regularly and frequently from disasters like floods, cyclone storms, tidal surges, river bank erosion and earthquakes. Practical implications: Incorporating knowledge of information management system is becoming increasingly important in the derivation of management solutions for disasters. Originality/value: Information systems including GIS, communication technology, other information retrieval and information management systems should be maintained during natural disasters to reduce the cost and time for contingency. In this paper, an attempt is made to highlight the role of information technology in the management of natural disasters in Bangladesh. © Emerald Group Publishing Limited. Source

Environmental Monitoring and Assessment

This study was conducted to investigate the contamination level of heavy metals in soil and vegetables, chemical speciation, and their transfer to the edible part of vegetables. Metals were analyzed using inductively coupled plasma mass spectrometer (ICP-MS). The ranges of Cr, Ni, Cu, As, Cd, and Pb in agricultural soils were 3.7–41, 3.9–36, 3.7–46, 2.3–26, 0.6–13, and 4.5–32 mg/kg, respectively. The metals were predominantly associated with the residual fractions of 39, 41, 40, 40, 34, and 41 % for Cr, Ni, Cu, As, Cd, and Pb, respectively. Considering the metal transfer from soil to the edible part of vegetables, the mean transfer factors (TFs) were in the descending order of Cu > Ni > Cr > Pb > As > Cd. In the edible tissues of vegetables, the concentrations of As, Cd, and Pb in most vegetable samples exceeded the maximum permissible levels, indicating not safe for human consumption. Total target hazard quotient (THQ) of the studied metals (except Cr) from all vegetables were higher than 1, indicated that if people consume these types of vegetables in their diet, they might pose risk to these metals. Total values of carcinogenic risk (CR) were 3.2 for As and 0.15 for Pb which were higher than the US Environmental Protection Agency (USEPA) threshold level (0.000001), indicating that the inhabitants consuming these vegetables are exposed to As and Pb with a lifetime cancer risk. © 2015, Springer International Publishing Switzerland.

The research was conducted to determine the performance of indigenous chicken through management interventions and compare with traditional husbandry practices. It was found that local chickens of Bangladesh lay average 3 clutches and annual egg production of about 45 in a year, average clutch duration 17 days and yielding 15 eggs in each clutch under scavenging management. About 124 days needs to complete a production cycle. Survivability of village chicks is about 43% and about 30% of them reached the age of production. In this traditional management of local chickens, a rural household earn a minimum bare profit, 47.3 US$ (1 US$=70 BDT) per annum from poultry enterprises. Management interventions like separation of chicks (Weaning) and creep feeding of chicks helps to increase egg production and reduced mortality of local chickens. Weaning increases clutches from 3 to 6 and average production cycle completed with in 68 days. Egg production increases 4egss/clutch and total from 45 to 96 per hen in a year. Creep feeding system of management increases chick's livability from 43% to 87%. These enhance egg production and low mortality of family chickens might contribute to increase income from 47.3 US$ to 342 US$ per annum of the households. Source

The study was conducted to estimate the serum lipid levels in women using depot medroxyprogesterone acetate (DMPA). A total of 90 Bangladeshi married women of age group 15-40 years attending the Model Family Planning Clinic, Mymensingh Medical College Hospital, Mymensingh, from July 2010 to June 2011. Patients were classified into three groups comprising those using the drug for 3 months (n=30), 1 year (n=30), and 2 years (n=30), respectively, compared to a control group (n=30) of married non-hormonally treated women of similar ages. Their age, weight, height, BP and BMI were recorded; all the subjects were clinically examined. Blood samples were collected for biochemical assay of serum lipid profiling parameters, such as total cholesterol, HDL-C, TAG and LDL-C. Data were collected and processed according to the design and objectives of the study. A significant (p<0.01) decrease in serum total cholesterol was observed up to 1 year of using DMPA, but a sharp increase was observed in 2 years group. Likewise total cholesterol, HDL-C was significantly (p<0.01) decreased in the 1 year group and rapidly increased in the 2 years group. A significant (p<0.01) reduction in TAG level was observed throughout the study tenure when compared with control group. No significant (p>0.05) difference in LDL-C level was observed among the treatment groups. The study concludes that DMPA induced significant alterations in lipid profiling parameters of the studied population and prolong use does not have risk of atherosclerosis; however, further study with a larger sample size is suggested for a general recommendation.
