SERUM VITAMIN E, C AND A LEVEL IN LUNG CANCER: A CASE CONTROL STUDY

Lung cancer is a leading cause of cancer death worldwide, causing approximately 1.2 million deaths per year. Lung cancer is prevalent in smokers. It is documented that smoking induces oxidative stress, which is thought to be associated with the aetiology of carcinogenesis. A case control cross sectional study was conducted on sixty lung cancer patients and sixty smokers as cohort control. Serum levels of antioxidant vitamin E, C and A among the case and control subjects were estimated. It was observed that vitamin E value among the study population did not alter (15.67±3.67μmol/L vs. 14.66±3.88μmol/L). It was within normal range. Conversely, there was significantly high serum concentrations of vitamin C and A in the lung cancer patients as compared to those in the smoker controls (48.26±6.81versus 16.65±4.46μmol/L; 2.76±0.32 versus 1.60±0.35μmol/L respectively)

Factors affecting consumers preferences on fast food items in Bangladesh

This article was published in Journal of Applied Business Research (JABR) [© 2010 Journal of Applied Business Research (JABR)] and the definite version is available at : http://cluteinstitute.com/ojs/index.php/JABR/article/view/313/303 The article website is at: http://www.cluteinstitute.com/journals/journal-of-applied-business-research-jabr/ DOI: http://dx.doi.org/10.19030/jabr.v26i4.313Fast food industry is a high growing sector of Bangladesh. It is concerned with the tastes and habits of the people. The food-taking habit especially in fast food segment has been changing very fast over last decade among the people of Dhaka - the capital city of Bangladesh. The reasons could be attributed by the increase of awareness, growth of education, development of information technology, and expansion of television channels and print media in Bangladesh. Hence, this paper aims at identifying the preference factors of fast food consumers living in Dhaka city. This study was conducted among the university students who usually eat fast food at their leisure time. To conduct the study, a total of 250 respondents were interviewed with a structured questionnaire. Both descriptive and inferential statistics were used in analyzing the data. Multivariate analysis technique like factor analysis was performed to identify the preference factors of the fast food student-consumers of Bangladesh. Multiple regressions were run to identify the relationship between the factors identified and the overall preference of the consumers. Results show that the consumers give most importance on brand reputation of the food item followed by nearness to receive and accessibility, similarity of taste with previous experience, cost and quality of the food, discount and taste, cleanliness and hygiene, salesmanship and decoration, fat and cholesterol level, and self-service factors. This study suggests that the brand reputation, nearness and accessibility, similarity in taste, and cost and quality relationship should be emphasized to improve the attraction of the university students towards the fast food items in Bangladesh.Publishe

Higher Order Markov Structure-Based Logistic Model and Likelihood Inference for Ordinal Data

Azzalini (1994) proposed a first order Markov chain for binary data. Azzalini’s model is extended for ordinal data and introduces a second order model. Further, the test statistics are developed and the power of the test is determined. An application using real data is also presented

Removal of Copper from Aqueous Solution Using Orange Pell, Sawdust and Bagasse

Orange peel, sawdust and bagasse have been used as adsorbents for the removal of Cu(II) from aqueous solution. The effects of contact time, pH, concentration, dose and ionic strength on the removal of Cu(II) have been studied. Moreover, treated sawdust has been used as an adsorbent for the same. The equilibrium adsorption capacity of the adsorbents for Cu(II) was obtained by Langmuir isotherm. The ionic strength effect on the removal of Cu(II) from its aqueous solution indicated that the removal followed ion-exchange mechanism

A review on the mobile applications developed for COVID-19: An exploratory analysis

The objective of this research is to explore the existing mobile applications developed for the COVID-19 pandemic. To obtain this research objective, firstly the related applications were selected through the systematic search technique in the popular application stores. Secondly, data related to the app objectives, functionalities provided by the app, user ratings, and user reviews were extracted. Thirdly, the extracted data were analyzed through the affinity diagram, noticing-collecting-thinking, and descriptive analysis. As outcomes, the review provides a state-of-the-art view of mobile apps developed for COVID-19 by revealing nine functionalities or features. It revealed ten factors related to information systems design characteristics that can guide future app design. The review outcome highlights the need for new development and further refinement of the existing applications considering not only the revealed objectives and their associated functionalities, but also revealed design characteristics such as reliability, performance, usefulness, supportive, security, privacy, flexibility, responsiveness, ease of use, and cultural sensitivity.Comment: 11 pages, 3 figures, 4 table

Economics of small scale irrigation and resource use plans in the Bogra District of Bangladesh

Food production in Bangladesh has always been less than what is needed for domestic consumption. To meet the food deficit every year it has to import food grain from outside. Irrigation can play a major role in the production of food grain in Bangladesh and can help to alleviate the situation. The pressure of population and the need for additional food supplies are necessitating the spread of irrigation throughout the country. Most of the surface water now available for exploitation is already being used. There is great scope to increase the irrigated area in winter (dry months) by exploiting underground water using tubevjells (deep or shallow) in Bangladesh. In this study financial analysis and linear programming techniques are applied to investigate the impact of shallow tubewell irrigation at micro level on cropping pattern, farm income, economics of enterprise combination and resource allocation. The results of the criteria used for financial analysis have been found to be encouraging. The analysis gives positive net present values and high financial rate of return as a result of shifts in the cropping pattern towards the high yielding varieties of rice and as a result of low cost of investment for each tubewell. Sensitivity analysis even at 10 per cent increase in all costs, other things remaining the same, also indicates the soundness of the project. Linear programming technique is employed to determine for resource allocation purposes the optimum farm plan (i.e. that plan yielding the highest total gross margin) with and without irrigation. The analysis suggests that although the total gross margin with optimal allocation of resources without irrigation increases considerably compared to original plan, with shallow tubewell irrigation in the optimum plan total gross margin is increased further. Farm income, with irrigation, increases mainly as a result of increased cropping intensity and introduction of high yielding rice crops which are found to be more profitable under the existing resources and constraints compared to the local varieties. With irrigation, optimal allocation of the resources increases the labour absorption capacity of the farm considerably. This indicates that underempoyment and unemployment prevailing in the study area can be reduced with tubewell irrigation. Parametric programming relaxing the production credit with irrigation implies that if more credit is made available to the tubewell farmers, it would further increase the total gross margin. With maximum absorption of production credit, total labour requirement will also increase which will further alleviate the underemployment problem. The major policy implication of the results of the study is that the potential to increase the total gross margin exists in the tubewell farms with optimal resource allocation. Considerable increase in food grain production is also feasible with irrigation. To enable the farmers to implement the optimum farm plans and to achieve the full benefits of irrigation, agricultural extension and research activities should be carried out in this respect with co-ordinated effort
