Abstract: Background: Clinical presentation of intestinal tuberculosis is varied. It is also essential to know the clinical and demographic characteristics of incidentally detected intestinal tuberculosis patient. Objective: The purpose of the present study was to find out the clinic-demographic characteristics of intestinal tuberculosis in clinically and preoperatively unsuspected laparotomies. Methodology: This cross-sectional study was carried out in the Department of Surgery at Dhaka Medical College Hospital, Dhaka from March 2002 to March 2004 for a period of two (2) years. All the patients underwent laparotomy presented without any suspicion of pulmonary or intestinal tuberculosis were included as study population. Patients who were without the history of cough, haemoptysis, antitubercular drug therapy were included. Per operative suspicion was raised due to enlarged lymph nodes in mesentery, omental masses, ileocaecal masses, suspicious growth in ileum, omental thickening, perforation suspected by tuberculosis. Biopsy was taken from suspicious lesions. Histopathology was confirmed the tubercular lesion. Results: A total number of 300 patients under laparotomy were recruited for this study of which 38 positive cases were found in the study with a percentage of 12.7%. Maximum affected age group was 21 to 30 years which was 16 (42%) cases. Male was predominant to female which was 28 (73.7%) cases and 10 (26.3%) cases respectively. Low socioeconomic people are affected more (76.3%). Most common presentation in positive cases was acute and sub-acute intestinal obstruction 20 (52.6%) followed by intestinal perforation (26.31%). Conclusion: In conclusion young age male patient is the most commonly affected intestinal tuberculosis which is frequently presented with sub-acute intestinal obstruction among the preoperatively unsuspected laparotomy patients.

Abstract: This is a case report of a patient with chest pain who had normal noninvasive investigations at various occasions. He was put on anti anginal therapy and advised follow up. Moreinvasive investigations were not carried out at that time because of negative exercise tolerance test (ETT).Patient had repeated visits with atypical chest pain and no electrocardiogram (ECG) evidence of ischemia duringpain or during ETT. At one such visits patient was advised Trop-T that turned out to be positive. Coronaryangiogram was advised and that revealed critical disease in his Left circumflex coronary artery (Cx). It wastreated with intra coronary stents, and patient became symptom free. This is one of those cases with normalECG during ischemic anginal episodes and normal ECG during exercise induced ischemia.

International Journal of Computer Science Issues , 2011,
Abstract: This paper picturesquely depicts the comparison of different methodologies adopted for predicting the load demand and highlights the changing trend and values under new circumstances using latest non analytical soft computing techniques employed in the field of electrical load forecasting. A very clear advocacy about the changing trends from conventional and obsolete to the modern techniques is explained in very simple way. Load forecast has been a central and an integral process in the planning and operation of electric utilities. Many techniques and approaches have been investigated to tackle this problem in the last two decades. These are often different in nature and apply different engineering considerations and economic analysis. Further a clear comparison is also presented between the past standard practices with the current methodology of electrical load demand forecasting. Besides all this, different important points are highlighted which need special attention while doing load forecasting when the environment is competitive and deregulated one.

Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.74028
Abstract: World energy consumption increased by 56 percent, from 524 quadrillion Btu in 2010 to 820 quadrillion Btu in 2040. The increased demand in energy consumption is fulfilled by different renewable and non-renewable sources such as petroleum, natural gas, electricity, nuclear etc. Natural gas is one of the most important sources of energy. SNGPL has been managing a 94,263 km long gas pipelines network covering approximately the northern part of Pakistan. In this paper we have presented the use of condition based maintenance (CBM) management techniques with ageographical information system (GIS) for asset management of a gas distribution network ofSNGPL. The continuous monitoring and updating of asset data reveal where the assets are located and which needs maintenance or which lies in critical condition. The system helps to save time and reduce visits to the sites and labour reduction.

Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.75041
Abstract: Flood is one of a kind of disasters which harms human and animal life around the globe. Pakistan has been observing massive floods for many years because of daily and seasonal variation in the temperature levels. Wheat, rice, sugarcane and cotton are major crops cultivated in Punjab region of Pakistan in which rice and sugarcane are mostly effected by floods. In this research paper, damage assessment of cultivated land in district Hafizabad along Chenab River has been calculated. Supervised Classification and Soil Adjusted Vegetation Index (SAVI) methods are applied. Pre-flood 2014, post-flood 2014, and pre-flood 2015 Landsat 8 images have been used to calculate the extent of damages to cultivated lands. Water, sand, silt, bare soil and vegetation are classified to identify damage. Results show that vegetation cover has plummeted to 50% after the arrival of flood 2014 in the Chenab. Similarly, 6.7047% of sand and 15.7339% of bare soil deposits have surfaced which have not yet been removed from fertile lands in 2015. 18.4376% standing crop damage has been analyzed under this study. 14.0245% silt deposits have been calculated as post-flood effects. 46.4260% land has been cultivated in 2015 which is 15.5024% lower than 2014 cultivated land. Furthermore, field verification survey has given promising results and has a great correlation with satellite based recovery results.

Abstract: River bank erosion is one of the frequent but the most unpredictable disasters that occur every year in Bangladesh. In this paper, Landsat TM-5 and Landsat-8 imageries from 1989 and 2015 were used to detect changes of present land use, river erosion and bar deposition in Chowhali Upazila, Sirajganj district of Bangladesh. This study reveals that human settlement, forest, seasonal crops and agriculture features decrease, while river coverage increases dramatically. About 1340 hectare areas have been eroded, while 630 hectares are deposited as channel bar in the study area over the last 26 years. Finally, an accuracy assessment is conducted between the test data and each land use feature. The overall classification accuracy was 97% and 98% in 1989 and 2015 respectively. Moreover, 98% accuracy is found in erosion while 97% is found in bar deposition areas.

Nasir Mehmood Minhas, Qurat-ul-Ain  , Zafar-ul-Islam  , Atika Zulfiqar
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.79072

In this research, an improved framework for requirement change management in global software development (RCM_GSD) has been presented. The objective is to manage the change in requirement specifically in global software development in an appropriate manner. The proposed frame-work RCM_GSD follows the required processes of RCM and reduces the concerns of GSD. Systematic Literature Review (SLR) was conducted for exploration of relevant research. During literature study, it is analyzed that the existing techniques of change management were not suitable for global software development (GSD). The change in requirements becomes more complicated in distributed environment due to the lack of communication and collaboration among globally dispersed stakeholders. The proposed model is compared with other models proposed in recent literature and analysis is made between them; feedback was obtained from the domain experts as well. The feedback and comparison results show that the proposed model provides an appropriate solution for requirement change management in GSD.

Abstract: Tuberculosis (TB) is a major health care burden in developing countries. With a high number of population living in an environment with high congestion, controlling TB in Bangladesh especially in urban areas has been a big challenge. The current study aims to identify the perception and treatment practice of formal and informal health service providers regarding TB in terms of treatment, referral system and to find out the partnership mechanism and also community perception and their health seeking behavior in two urban slums of Dhaka city. This is a cross-sectional study utilizing mixed methods approach and was conducted in two urban slums, namely, Slum A and Slum B of Dhaka city. Health service providers both formal and informal, community people and TB patients were selected as study population. In the quantitative part a survey was carried out where all the existing health service providers were interviewed. These health service providers were identified through 12 PRA (Participatory Rapid Appraisal) Social Mapping. Seven Focus Group Discussions (FGD) were conducted with this community. Popular Health service providers were identified through PRA matrix ranking during the FGDs and were selected for in-depth interview. TB patients were identified during FGD for in-depth interview. Community in urban slums is well aware of the infectious, contagious characteristics of TB. However, the long duration of DOTS program has been a major cause of high rate of drop-out. Generally drug sellers, traditional healers, homeopath and allopath (MBBS) practitioners are the primary point of contact of TB patients. They know where to refer to diagnosis and treatment. The referral system based on informal relationship sometimes leads to referring patients to wrong service providers. The mechanisms of TB programs in urban areas of Bangladesh should seriously consider arranging regular training and monitoring of health workforce, setting up formal partnership between formal and informal health service providers and generate information that policy-makers could use to scale up TB control program.
