The present study explores the chemical and economic aspects of pesticide contamination of marinefishery in relation to nutritional values Marine Pollution of pesticides poses signify can tricks to the environment and non-target organisms ranging from beneficial marine micro organisms, to insects, seaweeds, fish, and mangroves at Karachi Coast. Fish typically contains good quality nutrition, particularly oily fish has maximum commercial values but contamination of fishery is the major problem caused by pesticides and PCBs pollution resulting in serious health hazards. A number of fish and shell fish samples were analyzed for determination of pesticides contamination due to marine environment pollution. It was found that most pesticides pose risk to humans, fishery or the environment because they are designed to kill or adversely affect living organisms. Quantitative analysis of pesticides and PCBs was performed using GC equipped with ECD and the FPD for organophosphorus and GC-MS. The arithmetic mean concentrations of each pesticide were calculated and statistical evaluation was done. Relationship of protein and pesticides level has been determined to determine impact of pesticide on protein content of each type of fish. There is a considerable difference found in the pesticides contents of each type of fishery, which reveals that environmental pollution status that attributes towards pesticides distribution.

Abstract: This paper aims at demonstrating the current educational conditions of Pakistan, particularly concerning the government schooling system and the application of GTM, which renders students less productive and creative in their area of interest. This paper also aims at projecting the fact that every student has different needs, and in order to device a successful way of learning, it must not be overlooked the fact that these very needs should be taken into consideration so thatlearning native and target language must not be considered a hurdle. In Pakistan, there is a need of carrying out a productive way, whereby the process of both teaching and learning could be made effective. The subject domain under which this research is being carried out is Applied Linguistics, as the paper requires the knowledge, skill and application of language learning process as a whole. Applied Linguistics in this case helps us determine the thought, and puts itinto action, as to what is the actual purpose of language and how it must be taught and inculcated into the learners’ mind.

Asian Journal of Plant Sciences , 2002,
Abstract: Chickpea stem cuttings were used for vegetative propagation to multiply wild Cicer species and F1 hybrids produced from intraspecific hybridization. Stem cuttings of three varieties were treated with different concentrations of root inducing hormones NAA and IAA to compare and standardize the optimum concentration of these hormones. Three different concentrations (0.25, 0.5 and 1 mg l-1) of NAA induced 100 % rooting within ten days in all varieties. Wild Cicer species and F1 hybrids with less number of seeds were treated with 0.5 mg l-1 of NAA. About 10-13 plants were produced from every F1 seed. All plants performed well in the field and produced sufficient quantity of seed.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2010, DOI: 10.4236/jmmce.2010.912081
Abstract: The failure of steel components in multistage flash (MSF) desalination or power plants as a result of the deposition of carryover heavy metals/oxides is a common problem and reported by many authors. The present investigation was undertaken to study the corrosion behavior of mild steel and AISI 304L SS in presence of dissolved Cu ions under different experimental conditions. The experimental conditions include: variation in aqueous medium, Cu ion concentration, pH and flow condition. The corrosion rate of mild steel and SS 304L in presence of different concentration of Cu was determined by weight loss measurements and solvent analysis of iron ions into the test solution after completion of immersion. The amount of Cu ions present in the test solution after completion of immersion was also estimated using Atomic absorption spectrophotometer. The pH of the test solution was monitored during the entire period of immersion. Electrochemical techniques like free corrosion potential measurements and potentiodynamic polarization measurements were carried to find out the role of Cu ions on the corrosion behavior of mild steel and SS 304L. The effect of Cu on corrosion rate of mild steel is quite pronounced and follows interesting trend. However, SS 304L is not affected either in distilled water or artificial seawater and do not show any significant variation in corrosion rates in presence of Cu ions.

Abstract: Objectives: 1). To study the genotypic differences, if any, betweenPakistani children suffering from Wilson’s disease from those in the west and to correlate phenotype with genotype. 2).To find out the most frequent mutations present in our patients and screen out asymptomatic siblings of the index cases.Setting: Department of Pediatrics, Allied Hospital, Punjab Medical College, Faisalabad. Duration: May 1997 to June2005. Materials and methods: 41 patients ranging from 5-18 years were diagnosed based on clinical and laboratorydata. 13 patients and 6 asymptomatic siblings along with their parents were subjected to mutation analysis. at Universityof Vienna, Austria. Results: None of the patients had His1069Gln, the commonest European mutation. R969Q andI1102T detected in our patients have previously been described. Four novel mutations were found. Asymptomaticsiblings screened were either heterozygote or normal. R969Q appears to be associated with sub-acute liver diseasewith hepatosplenomegaly. I1102T was seen in children with chronic liver disease and L1071W, C1079Y and E583R-fs(insA) with early onset of neurological disease. Conclusion: Our Patients are phenotypicaly as well as genotypicalydifferent. Different genotype could be responsible for the phenotype. Further studies are needed with a larger samplesize so that molecular genetic tests be devised for early diagnosis and family screening.

Abstract: OBJECTIVES: To study clinical and diagnostic laboratory features of tuberculous meningitis (TBM) inchildren. STUDY DESIGN: Prospective cohort study. PATIENTS & METHODS: Children diagnosedas TBM in Paediatric ward Allied Hospital, Punjab Medical College Faisalabad were included in the study.Complete history and clinical examination was recorded. Complete blood count, ESR, Chest X Ray, Mantouxtest were done. CSF was subjected to biochemical and microscopic examination. CT scan (computerized axialtomogram) of brain, plain and contrast was done in all patients. RESULTS: One hundred children wereincluded in the study. 67% were below five years of age. 78% belonged to lower socioeconomic status. 82% weremalnourished. 26% were vaccinated while 74% were unvaccinated. History of contact with a tuberculous patientwas found in 48% of patients. 69% were in stage III TBM, 31% in stage II. 74% had focal neurological deficitwith hemiplegia being the commonest one. 73% had convulsions. Most patients presented quite late, 29% werecomatose for more than two weeks before coming to the hospital . 28% were in decerebrate or decorticate posture.Atypical clinical findings were also noticed. 43% had high grade fever from the onset of illness, 14% had anabrupt onset with symptoms developing in less than one week. 39% had encephalitic TBM. 31% had extrapyramidal signs. Mantoux test was >10 mm in 17% cases, suggestive chest X-Ray in 80% and typical CSFfindings in 46%. 37% had normal CSF glucose, 8% had predominant polymorphs in CSF. Abnormal CT scanwas found in 85% cases with hydrocephalus as commonest CT abnormality observed. CONCLUSIONS: Ahigh index of suspicion is needed to diagnosis TBM in children. A combination of epidemiological , clinical andlaboratory data should be used to make an early diagnosis.

Abstract: Introduction: Celiac disease is an autoimmune inflammatory disorder ofsmall intestine precipitated by ingestion of gluten. Clinical and histological improvement occurs on withdrawal of glutenfrom the diet. Objectives: The present study were to identify the trace mineral deficiency in newly diagnosed celiacchildren and to assess how far these deficiencies are corrected after strict gluten free diet. The study also assessedthe nutritional status of celiac children compared to the healthy controls before and after Gluten Free Diet. Setting:Department of Pediatrics Punjab Medical College Faisalabad. Duration: January 2004 to March 2005. Study Design:Interventional case control study. Patients and Methods: 22 children aged 2 to 14 years diagnosed as Celiac diseaseon the basis of typical intestinal biopsy findings were included. 15 healthy children served as controls. Anthropometricmeasurements and serum Zinc Copper Magnesium and Iron along with albumin were done for both patients andcontrols initially and repeated after 6 months while patients were receiving strict GFD and controls receiving normaldiet. The general linear model was used for the analysis of variance using SPSS (2004). Results: Serum Zinc wasbelow the reference range in 68%. Serum copper and Magnesium in 31%, Iron in 95%and albumin in 59% of thepatients. There was a statistically significant increase in serum zinc, iron and magnesium levels (p value, < 0 05) whileserum copper and albumin did not show any significant rise after Gluten free diet. Control group did not show any significant change in their trace mineral levels .Celiac patients gained more weight (mean 4.47 versus 2.91 cm) andheight (3.34cm versus 1.022 cm) as compared to the control group. Conclusion: Celiac children receiving strict Glutenfree diet and showing good clinical response probably do not need mineral supplementation.
On the Effects of Complex Conjugate Medium on TM Scattering by a Strip  [PDF]
Amjad Imran, Ahsan Illahi
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2011, DOI: 10.4236/jemaa.2011.37043
Abstract: In this paper, Method of Kobayashi Potential is used to determine the scattering behavior of a strip which is placed at the air-complex conjugate medium interface. And discussion is presented that how the complex conjugate medium mod-ify the scattering properties of the strip. A comparison is also given with that if we replace the conjugate medium with standard dielectric medium. E-polarized electromagnetic plane wave is supposed to be obliquely incident upon the ge-ometry. Scattered fields in both the half spaces are supposed in terms of unknown weighting functions. Discontinuous properties of Weber-Schafheitlin integral and orthogonal properties of Jacobi’s polynomials are used to determine these unknown weighting functions. Far scattered fields have been calculated using Saddle Point Method and computed for different parameters of interest.

Open Journal of Forestry (OJF) , 2016, DOI: 10.4236/ojf.2016.62011
Abstract: Mammals were studied at the Baraiyadhala National Park, Chittagong from August 2012 to July 2013. Twenty nine species of mammals belonging to 26 genera, 17 families and 9 orders were recorded. Of the recorded species, 2 were primates, 10 rodents, 1 lagomorph (hare), 5 chiropterans (bats), 1 manid, 7 carnivores and 3 ungulates. Rodentia appeared as the largest family contained 10 speices. The overall mammalian population density was 239.12/km2. Irrawardy squirrel (Callosciurus pygerythrus) scored the highest density (112.97/km2) and several species attained the lowest (1/km2 each). Local status (relative abundance) of mammals assessed where 15 (51.72%) species were rare, and according to National Conservation Status, 13 (44.82%) were remarked as threatened species of that area. There were some major threats to the park such as forest fire, encroachment of forest and forest edges by both tribal and landless people, illegal exploitation of forest resources, grazing of livestock and unavailable water reservoirs.
