Abstract: Unmanned Aero Vehicles (UAV) has become a useful entity for quite a good number of industries and facilities. It is an agile, cost effective and reliable solution for communication, defense, security, delivery, surveillance and surveying etc. However, their reliability is dependent on the resilient and stabilizes performance based on control systems embedded behind the body. Therefore, the UAV is majorly dependent upon controller design and the requirement of particular performance parameters. Nevertheless, in modern technologies there is always a room for improvement. In the similar manner a UAV lateral control system was implemented and researched in this study, which has been optimized using Proportional, Integral and Derivative (PID) controller, phase lead compensator and signal constraint controller. The significance of this study is the optimization of the existing UAV controller plant for improving lateral performance and stability. With this UAV community will benefit from designing robust controls using the optimized method utilized in this paper and moreover this will provide sophisticated control to operate in unpredictable environments. It is observed that results obtained for optimized lateral control dynamics using phase lead compensator (PLC) are efficacious than the simple PID feedback gains. However, for optimizing unwanted signals of lateral velocity, yaw rate, and yaw angle modes, PLC were integrated with PID to achieve dynamical stability.

Abstract: We aim to develop and trial a complex intervention to reduce tobacco dependence among TB suspects based on the WHO 'five steps to quit' model. This model relies on assessing personal motivation to quit tobacco use and uses it as the basis for assessing suitability for the different therapeutic options for tobacco dependence.We will use the Medical Research Council framework approach for evaluating complex interventions to: (a) design an evidence-based treatment package (likely to consist of training materials for health professionals and education tools for patients); (b) pilot the package to determine the delivery modalities in TB programme (c) assess the incremental cost-effectiveness of the package compared to usual care using a cluster RCT design; (d) to determine barriers and drivers to the provision of treatment of tobacco dependence within TB programmes; and (e) support long term implementation. The main outcomes to assess the effectiveness would be point abstinence at 4 weeks and continuous abstinence up to 6 months.This work will be carried out in Pakistan and is expected to have relevance for other low and middle income countries with high tobacco use and TB incidence. This will enhance our knowledge of the cost-effectiveness of treating tobacco dependence in patients suspected of TB.Trial Registration Number: ISRCTN08829879Eight out of every ten smokers live in low- and middle-income countries[1]. In several of these countries, tobacco use is on the increase. Consequently, 70% of the projected mortality secondary to tobacco use is likely to be borne by low- and middle-income countries[1]. In addition, people die at an earlier age in such countries, causing the loss of 20-25 years of productive life[2]. Cost of cigarettes is relatively high in low- and middle-income countries compared to food and other essential commodities, resulting sometimes in their substitution. Therefore, tobacco use puts enormous burdens on countries' already ailing economies and co

Abstract: Rural livelihoods in Sindh recorded an improvement despite financial constraints, expenditure doubled between 2001 and 2006 growing at an average rate of 23% per annum. Public sector contributed significantly through various interventions on poverty alleviation but the most worrying situation was the expenditure on food subsides, food support programs and low cost housing has been stagnant even in nominal terms with negative repercussions for the poor and the needy. Sindh Agricultural and forestry workers coordinating organization has made social mobilization as core activity and entry point followed by different development interventions. The Agha Khan rural support program provides a one time grant to complement village organizations to the infrastructure projects. The national rural support program has lowered the levels of poverty in member households. The Pakistan poverty alleviation fund educational program provides quality learning at primary level in district Sanghar. Similarly PPAF has also improved health care through the provision of quality basic health services. The young Sheedi welfare organization has establish emergency centre for disaster preparedness and provided 600 goats to 200 beneficiaries. Badin rural development society through their effort 1500 women and 2800 men in 60 villages are engaged in development process. The major strength of NGOs was that they have special ability to reach the poor and other segments of society while their major weakness is small size and budget and lack technical capacity to confront difficult situation. It is recommended that NGOs should ensure that new technologies are introduced to help farmers improve and increase crop production.NGOs should create a condition in which the poor are either given or enabled to acquire their assets and a peaceful environment to benefit from those assets. Government should provide facilities for institutional building to the local NGOs this will encourage them to work sincerely towards poverty alleviation.NGOs should not rely on government for future projects instead they can raise funds through savings and donation from rich individuals.

Abstract: Hyperlipidemia is associated with diabetes and hepatotoxicity has emerged as a common clinical complication by antidiabetics. The present study was conducted to determine the antihyperlipidemic and hepatoprotective activity of Dodonaea viscosa leaves extracts in the alloxan-induced diabetic rabbits. The rabbits (n = 70) were divided into seven groups including normal and diabetic control, the remaining were aqueous, aqueous:methanol (70:30), aqueous:methanol (50:50), aqueous: methanol (30:70), and methanol extracts given for 30 days. Serum levels of triglycerides, total cholesterol, LDL-cholesterol, HDL-cholesterol, ALT and AST were estimated by using commercially available kits. The oral administration of aqueous:methanol (70:30) extract of the Dodonaea viscosa leaves significantly (P<0.01) decreased the raised parameters (triglyceride, total cholesterol and LDL-cholesterol) to normal values. But the extract has significantly increased HDL-cholesterol, ALT and AST levels. For the aqueous:methanol (70:30) extract given animals, the average serum level of total cholesterol was 60.00±1.30 mg/dL, LDL-cholesterol was 92.80±2.29 mg/dL, HDL-cholesterol was 31.80±1.0 mg/dL and triglyceride was 15.40±0.75 mg/dL while the average serum levels of ALT and AST were 45.60±3.08 and 27.20±1.36 IU/dL, respectively. It is concluded from the study that aqueous:methanolic (70:30) extract of Dodonaea viscosa leaves exerts antihy- perlipidemic and hepatoprotective effects in the alloxan-induced diabetic rabbits.

Abstract: A comparative trial was conducted to study the relative efficacy ofendoscopic injection sclerotherapy versus endoscopic injection sclerotherapy plus octreotide with reference to acutecontrol of bleeding esophageal varices and early re-bleeding. A total of 58 patients equally divided in two groups wereincluded in this study. Bleeding was controlled in 90% patients in both the groups. In group1 there were 20(68.96%)males and18(62%) males in group 2. The mean age of the patients under study was 50.62 &50.55 in group 1& 2respectively. The major proportion of patients was in Child Class B, which comprised of 42(72.41%) in total. ChildClass C was excluded out of study. Twenty-two (75.86%) patients in group 1 were in Child Class B and 7(24%) werein Child Class A & in group 2 there were 20 (68.96%) patients in Child Class B and 21% were in Class A. Etiology ofcirrhosis was HCV in 41(70.86%) and HBV in 9(15.5%) and other etiologies in remaining patients. In, group 1,HCVrelated cirrhosis was seen in 20 (68.96%) and in group 2, this was responsible for cirrhosis in 21(70.68%) of patients.Patients suffering from HBV related cirrhosis were 5(17.42%) in first group and 4(13.79%) in second group 2. Relativelyless number of patients in group 2, had rebleeding in first week of their in-hospital follow-up i.e. 5 versus 8 patients.Average number of blood transfusions per patient was 3.86 piants in group 1and 2.45 piants in group 2. The meanduration of Hospital stay was 8.52 days in group 1 and 7.45 days in group 2. Procedure related complications and inhospital outcome was almost comparable in two groups. The most common complication was hepatic encephalopathy.Combining endoscopic therapy with one of the vasoactive agents reduces the chances of early re-bleeding and needfor number of blood transfusions and duration of hospital stay.

Abstract: Objective: To explore the pattern and prevalence of inpatient psychiatricmorbidity and to see how it differs from the pattern of psychiatric morbidity in community. Design: The details of all inpatientsfrom the case register developed for a health information system was included in study Setting: In Departmentof Psychiatry and Behavioral Sciences, Bahawal Victoria Hospital, Bahawalpur. Period: From 1998-2003. Results: Atotal of 5426 patients were admitted in the six year. There was a slight difference of 0.8% in total number of males andfemales cases (i.e., 2764 males Vs 2662 females). Overall difference reported in the present study, in mean ages ofmales and females was 3.45 years (i.e., males = 31.85 Vs females = 28.40). Mean stay of patients in ward is 10-12days. Most patients were admitted with Conversion disorder 24% followed by Schizophrenia 23%, Depressive disorder20%, Drug Dependence 10%, Bipolar Disorder 7%. The patients with Neurotic Disorder and Organic Disorder werebelow 5%. Conclusion: The study showed that overall general pattern of inpatient psychiatric morbidity is in line withpattern of psychiatric morbidity in community and the partial variance can be explained in terms of social variables, asthis variance exist even across studies within community samples.

Abstract: Objectives: To find out the sociodemographic characteristics ofconversion disorders and to find if there is any difference between the presenting symptoms of rural and urbanpopulation. Design: A non-probability, purposive, hospital based sample. Place and Duration of Study: Psychiatrydepartment of Victoria Hospital Bahawalpur, from February 2004 to April 2005. Patients and Method: A sample of 100-patients was collected. Both sexes were included. DSM-IV criteria for conversion disorder were applied for diagnosisof all these patients. Informed consent was taken for inclusion in the study. Patients suffering from concurrent physicaldisorders were excluded. The first author (NM.) using a semi-structured pro-forma interviewed all these patients. Thesociodemographic characteristics and the clinical profile were collected. Statistical analysis was made with the statisticalpackage for windows, SPSS (version –10). The applied method for group comparison was chi square- test. Results:The mean age of patients from the urban area was 24.26±7.25 years, as compared to 22.15±7.49 years for thepatients from the rural area. Most of the patients were females and were married. Majority of the patients from the urbanas well as from the rural area were uneducated and from the lower socio-economic class. The onset of illness wastypically acute and sudden, with precipitating life event. Majority of the patients had family history of the illness and comorbidpsychiatric disorders. The presenting symptoms were either sensory, motor, mixed symptoms and psuedoseizures.The presenting symptoms of patient from both urban (p value of 0.008), and rural area (P value =0.013), werestatistically significant. There were no statistically significant association between the presenting symptoms and thearea of living. The p values of the entire chi square tests were greater than (0.05). Conclusion: Prompt elimination ofthe symptoms of conversion disorder is important to prevent secondary gains from reinforcing it and causing it to persistor reoccur. Psychiatric services need to be developed and updated for the provision of prompt and efficient treatment,for the patients with these chronic and sometimes disabling conversion disorders.
