Effectiveness of IT in Business Education: A Case of Business Schools in Pakistan
Ahmad Kaleem
Pakistan Journal of Social Sciences , 2012,
Abstract: Lucrative, cost-effective and time saving developments in Information Technology have created a revolution worldwide. Pakistan is among the beneficiaries economies where the business community stimulates to incorporate IT resources in their organizational culture for speedy, reliable, and economical solutions. Local universities are no exception to that and are actively involved in research, training and developing IT-based systems, procedures and tools to transform conventional styles into effective and efficient IT led educational system. The study analyzes the effectiveness of IT in business education. The emphasis is on the impact of IT on business graduates academics. The study argues that mere allocation of funds for the development of IT resources does not produce the graduates of market expectations. Business schools have to ensure the effectiveness and efficiency of their investment and must also critically monitor the learning progress of their business graduates. Sample data of 254 business graduates is collected from the three leading universities of Lahore; COMSATS Institute of Information Technology, University of the Punjab and University of Management and Technology. Sample data also includes Government College University, Faisalabad as a special case which hires visiting faculty only. The findings conclude that business graduates from Government College University Faisalabad are more satisfied. Their graduates find significant improvement in studies after attending IT courses. Overall business graduates find more improvement in the general usage of computers and show deficiencies in specific usage (related to different specialized fields of business education). Majority of them recommended to include more practical issues and latest technology in IT curriculum.

Introduction: Laparoscopic assisted colonoscopic polypectomies have been well described in the literature and are well established in surgical practice, for removal of large, inaccessible, or flat based polyps. Laparoscope allows the endoscopist a serosal viewpoint and thus clear indication of perforation, in addition to enhancing endoscopic positioning through colonic mobilisation, facilitating polypectomy. We describe a previously rarely published technique, in which the colonoscope directs the surgeon to polyps and laparoscopy enables wedge resection of benign polyps using Endo GIA staplers. Using this method, the colonoscope provides an intra-luminal view ensuring adequate excision with margins whilst the laparoscope provides intra-peritoneal access for the wedge resection. Methods: This is a case series of 12 patients with large tubulovillous adenomas, found and biopsied at colonoscopy. Under a general anaesthetic, an on table colonoscopy was performed to identify and reassess the polyp, whilst a laparoscopy was performed to excise the polyp via wedge resection, using the endoscopic view as guidance. Results: The polyp was identified and completely resected in our 12 patients. All patients were discharged on the first post-operative day. Of the polyps excised, a focus of adenocarcinoma was detected in one and an adjacent endocrine tumour was found in another patient in histology along with tubulovillous adenoma. Rest were all tubulovillous adenomas only. Conclusion: We propose that this technique should be regarded as an alternative to Right hemicolectomies and difficult endoscopic mucosal resections for large adenomas, and be regarded as a definitive and safe procedure in its own right.

Exploring the Potential of Transient Receptor Potential: Troubleshooting Troublesome Calcium Thoroughfares in Biomedicine
Ammad Ahmad Farooqi,Abuzar Kaleem,Muhammad Khalid Javeed,Qaisar Mansoor
International Journal Bioautomation , 2010,
Abstract: Transient Receptor Potential-Canonical (TRPC) channels are the border guards residing in the supra-molecular assembly of plasma membrane. TRPCs represent a family of channels that have dual functions of store-operated and second messenger-operated channels in a diversity of cell types. Any disruption in the spatio-temporal organization drastically influences the calcium homeostasis. This review summarizes current interpretations on the infrastructure and characteristic divalent ions regulation in molecular anomalies. A specific targeting of these channels will enable us to get a step closer to personalized medicines.

Faisal Riaz,Kaleem Ahmed,Iftikhar Ahmad,Muhammad Ibrahim
International Journal of Computer Science & Information Technology , 2013,
Abstract: Cognitive radio based inter vehicle communication system was proposed by the researchers in 2010. Theyhave proposed cognitive radio site (CR-Site) inside the vehicle to solve the problems associated with thesingle radio access technologies (GSM/GPRS, CDMA, Wi-Fi) based IVC systems. Our main work isregarding the introduction of multi-homing module in CR-Site. After receiving quality of service (QoS)parameters from application cognitive system monitor (CSM) initiates white space optimization module tooptimize the white spaces package according to the requested QoS parameters. GA optimizes the whitespaces and sends them into the optimized white spaces pool. On the reception of admission acceptance,application sends the data for transmission to the scheduler via CSM. Scheduler initiates its sub moduledevisor to divide the data into the packets according to the smallest bandwidth in the optimized whitespacepackage. Then these packets are sent using multi white spaces in parallel fashion. Simulation andanalytical experiments reveal that using multi-homing heavy files (videos and text) can be transmitted inless time as compared to the non multi-homed single RAT (GSM or CDMA or LTE) based V2Vcommunication systems.

Ahmed Z. Kaleem, Nabish Naheed, Syed M. Ahmad
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.72017
Abstract: Background: Anastomotic leak is the most dreaded complication and it accounts for one third of post-operative deaths in colorectal surgery. There is strong need of research in this field in order to reduce anastomotic leak rate. If there was a test available to signify probability of leak at the time of surgery, it would potentially avoid a leak at a later date. Aim: We propose that intra operative use of narrow band imaging colonoscopy in left sided colonic anastomosis can predict and detect anastomosis related problems, problems i.e. vascularity, anastomotic lumen patency and rigidness of anastomosis which in turn lead to correction at the time of surgery resulting in significant decrease in anastomotic leak rate associated with morbidity and mortality. Methodology: A pilot, single blind, prospective, randomised controlled trial. Aim is to divide patient in 2 groups, containing 15 patients in each group. One group will be assessed by intra-operative NBI colonoscopy and other with standard technique. Analysis: This will be performed using SPSS with the help of statistician. Significance: This area of research is particularly important because it improves survival by reducing morbidity and mortality associated with anastomotic leak. If a leak is avoided then it does not only mean early recovery but it also saves NHS in terms of ICU care, NHS bed, inpatient nursing care and home help, unfortunately all required if leak is to occur. As a result, this research will have better financial implication with significantly improve patient care.

Colonoscopy a True Therapeutic Icon  [PDF]
Ahmed. Z. Kaleem, Nabish Naheed, Syed M. Ahmad
Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.87031
Abstract: Colonic polypectomy remained the first colonoscopic therapeutic intervention which was successfully accomplished with the help of an early snare. This therapeutic procedure was executed by Dehyle in Europe and Shinya in USA in 1971 [1]. Thus, these two colonoscopists acquired the pioneer’s position of therapeutic colonoscopy. Now the colonoscopy has achieved a special status in treating colorectal diseases because of its unique therapeutic aspect. The common uses of therapeutic colonoscopy are broadly classified in to the four major categories because of its unique therapeutic properties. These uses include resection and ablation, hemostasis, decompression with or without recanalization and foreign body extraction. Colonic perforation remained an absolute contraindication to therapeutic colonoscopy which is analogous to diagnostic colonoscopy. Good Communication plays a vital role in accomplishment of successful therapy with the help of colonoscopy. Consent process remained a complex process which should be well organized and tailored as per patient’s needs. There are lot of advancements in colonoscopy in recent years and many new procedures and treatment modalities have become available to treat colorectal diseases with the help of colonoscope. The recent advancement in colonoscopy has led to having many novel techniques. This therapeutic colonoscopy has made a significant change in current colorectal cancer management as polyps can be treated in the early stage, thus reducing the incidence of colorectal cancer. This is the basis of the United Kingdom existing bowel screening program, which is only feasible because of colonoscopy-induced interventions. The successful uses of these techniques obviate the need for a major surgical operation and colorectal disease can be treated with minimally invasive colonoscopic methods. These attributes make colonoscopy a true therapeutic icon.
Colonoscopy a Real Diagnostic Paragon  [PDF]

Surgical Science (SS) , 2017, DOI: 10.4236/ss.2017.86028
Abstract: Diagnostic colonoscopy acquires the status of gold standard investigation for evaluation of colonic problems. Formally, colonoscopy was first initiated in June 1969 in America. Colonoscopic history can be traced back to 1958. Matsunaga from Japan was the pioneer as he used a gastrocamera which was the start of colonoscopic era. Flexible sigmoidoscopy was later introduced in 1963. Existing colonic perforation and refusal of a fully compos mentis patient, remain absolute contraindications to diagnostic colonoscopy. Bowel Perforation, although less common, is a disastrous complication of colonoscopy. It is a basic right of any patient who has been offered a colonoscopic procedure to have appropriate, clear and concise information about colonoscopy. Consent literally means permission or an agreement which is granted by a patient to a health care individual to receive examination, test, treatment or intervention. Colonoscopic consent process should be valid and has voluntary, fully informed and capacity aspects as its integral components. There were a lot of oppositions against colonoscopy at that time. It was believed to be dangerous and unnecessary exercise by many surgeons. Time has proved that to be a wrong perception. It is now believed to be an extremely useful diagnostic modality. It is safe procedure in experienced hands and provides valuable clinical information. Colonoscopy is not a pleasant investigation as it is usually related with pain and discomfort by patients; fortunately, good analgesia and safe conscious sedation make this hostile but worthwhile procedure tolerable to patients.Today colonoscopy has kept its status of the gold standard investigation in diagnosing bowel cancer and has prime role in the assessment of majority of large bowel symptoms. Colonoscopy also retains the status of being an investigation with highest sensitivity and specificity, out of all available diagnostic modalities, for identifying adenomatous polyps and now it has acquired a unique status of being a diagnostic paragon.

Waqar A. Baloch,Musa Kaleem Baloch,Shahzada A. Saleem,Ahmad K. Baloch
Pakistan Journal of Biological Sciences , 2000,
Abstract: Water sorption properties of tomato powder at intermediate moisture range (0.11 to 0.88 Aw) was characterized and its storage stability evaluated at 40 C by following changes in carotenoid contents, browning and pH. The sorption isotherm produced was of the sigmoid shape with safe moisture level of 12 per cent which confirmed to 0.67 Aw. The rate of carotenoid breakdown decreased from 7.6 x10 -2 to 0.48 x10 -2 mg/g per hr with the increase in water activity from 0.51 to 0.67 aw and then it intensified sharply on further rise in water activity. Whereas, the rate for browning and pH increased continuously with gain in water activity. Since appearance of dense brown colour is more deterrent to quality of the product, the stock required for prolonged storage at 40 C may be maintained at a compromised lower water activity levels close to 0.67 aw so as to retain the desired quality characteristics of the product at an acceptable levels.

Pakistan Journal of Nutrition , 2011,
Abstract: A field experiment was conducted at the Agronomic Research Area of PMAS Arid Agriculture University, Rawalpindi to evaluate the quality parameters of spring planted sunflower hybrids as influenced by varying potassium application doses during two consecutive years i.e. 2008 and 2009. Experiment was quadruplicated using randomized complete block design with split plot arrangement keeping different levels of nutritional area in main plots and sunflower hybrids in subplots. Protein and achene oil contents were determined by Nuclear Magnetic Resonance Technique, where as fatty acid composition was determined by GC-9A Fatty Acid Analyzer. Different levels of nutritional area significantly increased protein content and palmitic acid concentration in achene but reduced oil content when levels of nutritional area vary from 60 x 20 cm2 to 60 x 60 cm2 (2 plants/hill). However, the concentration of oleic, linoleic and linolenic remained un-affected by varying levels of nutritional area. Hybrid Hysun-33 produced significantly higher protein content (18.89%) in achene as compared to S-278. Conversely, hybrid S-278 accumulated significantly higher oil content (43.48 %) as compared to hybrid Hysun-33. No proper pattern was noticed regarding stearic, oleic, linoleic and linolenic acid accumulation in achenes. It is concluded that sunflower hybrids exhibited differential genotypic response to different levels of nutritional area by increasing oil contents, palmitic acid concentration and reducing protein contents in achenes without affecting stearic, oleic, linoleic and linolenic acid concentration.
