Abstract: Information systems are mainly used by many organizations to improve efficiency of business activities by automatingexisting operations. Past researches in show that by adopting information systems we can increase firm performance. Results discovered that by adopting accounting information system there is significant improvement in performance. Accounting information system (AIS) is a superior system that focuses on user-orientation. Core objective of AIS is to collect and record data and information that is concerned to events that can economically impact upon firms. It processes information and communicate this useful information to internal and external stakeholders. This study intends to find the effects of Accounting Information system (AIS) on profitability of Pakistani firms. It investigates whether there is any difference between adopters and non adopters of accounting system. The sample data have been taken from sixty six of public listed companies on Karachi Stock Exchange (KSE) by purposive sampling dated from 2005 to 2009 period. Study used the four variables. Independent variable is ROA which measures profitability. Two independent variables are Leverage and Firm Size. Leverage is quantified using debt ratio and firm size is measured by taking natural logarithm of total assets. These independent variables are taken on the basis of high availability as determinants of profitability. Study intends to check the overridingrole of accounting system on this relation, so AS acts as intervening variable in the study.

Journal of Environmental Science and Water Resources , 2012,
Abstract: Dye house effluents of textile industries leads to severe environmental problems when disposed to aquatic bodies without proper treatment. This work was carried out to optimize the Photo-Fenton process for decolorization and mineralization of a commercial textile dye, Reactive Blue 222. The effect of different process parameters on decolorization efficiency of Photo-Fenton process was investigated. The optimal conditions for process were observed as; pH level 3.5, H2O2 concentration 1× 10-2M, FeSO4 concentration 3.5 × 10-5 mol L-1, temperature 50 C and process time 50 min. The maximum 95% dye decolorization was achieved along with a significant (P< 0.05) reduction of chemical oxygen demand and total organic. The degradation products were characterized by UV–visible and FTIR spectral techniques. The results provide evidence that Photo-Fenton process was able to oxidize and mineralize the selected azo dye into non-toxic metabolites.

Fluidized bed combustion behavior of coal and biomass is of practical interest due to its significant involvement in heating systems and power plant operations. This combustion behavior has been studied by many experimental techniques along with different kinetic models. In this study, SO2 emissions have been studied out in a pilot scale test facility of Circulating Fluidized Bed combustor (70 KW) under fast fluidized bed conditions burning coal with Pakistani wheat straw. One dimensional Mathematical model is being developed to predict the SO2 emissions under different operating conditions like bed temperature, Ca/S molar ratio, solids circulation rate, excess air ratio and secondary to primary air ratio. These parameters are varied to validate the model and encouraging correlation is found between the experimental values and model predictions.

Abstract: Rapid and reliable identification of olive plants using DNA markers has been attempted in the past but the selection of polymorphic regions for discrimination at varietal level remained obscure. Recent sequencing of plastid genome of the olive flaunts high resolution Cp markers for olive DNA fingerprinting. Using this information, we designed a combination of chloroplast markers to amplify genes recruited in photosynthesis, ribosomal and NADH energy metabolism for varietal identification of olive plants. Concatenated DNA sequences of more than 100 unknown and 10 reference plants samples were analyzed using various bioinformatics and phylogenetic tools. Conserved blocks of nucleotide sequences were detected in multiple alignments. Phylogenetic reconstruction differentiated the unknown plants into various clusters with known varieties. Further narrowing down of the samples through UPGMA tree clearly separated the plants into Arbosana, Frantoio and Koroneiki as the major varieties. Multiple alignments of these clusters revealed important variety specific SNPs including G and T nucleotides at specific positions. Sequence identifying at intra cultivar level was more than 98.79% while it dropped to 97%, and even to 96% at inter varietal level. Furthermore, a neighbor net network analysis separated these three clusters, thus validating the results of UPGMA tree. Over all, out of 100 plants samples, 49 plants were identified that fall into 10 varieties including Arbosana, Carolea, Chetoui, Coratina, Domat, Frantoio, Gemlik, Koroneiki,Leccino and Moraiolo. The maximum number of known plants belongs to Frantoio and Gemlik (8 each). The least number of samples was identified from Carolea, Domat and Moraiolo with 2 samples each. However, 51 plants could not be identified, as plants were not clustered with any of reference control. Our results have implications in on-farm conservation of olive germplasm and provision of genuine material for multiplication of authentic varieties. This strategy can be extended to varietal identification of other plant species.

Abstract: The situation of electricity in Pakistan has been alarming from the last ten years. The deficiency in electricity has not only obstructed the business activities but also affected the domestic consumers, educational institutes and hospitals. Usually electrical power companies are liable for electricity shortfall and power interruption. However, electricity end consumers are also equally responsible behind strange shortfall and unusual power interruption. Frequently, the consumers use the heavy electrical equipment in their homes including heaters, geysers, irons and water motors which causes the more electricity consumption, load shedding and huge amount of bills. For escaping the huge amount of electricity bill, the consumers commit the illegal and unethical connections. The illegal usage of electrical power failed the power companies to plan schedule load shedding accordingly and the other side the damaged electricity wires or Pole Mount Transformer increased faults due to overburdening, which directly affected on extend power interruption. In addition that, responsible teams of electrical power companies cannot reach instantly to repair faults and prevent the theft. Electricity thieving is social crime committed by the consumers or meter readers which causes the electricity strange shortfall within country. This paper presents the practical demonstration about the common energy theft methods and techniques done by electricity consumers within their home and residential building. In Pakistan EPC (electrical power companies) deploy the traditional electromechanical meters for electricity consumption measurements, however, these meters do not have any real time communication. Therefore there are many easy ways to manipulate the meter reading as well as internal structural of metering system.

Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/926017
Abstract: Let K be a closed convex subset of a real Hilbert space H and let be a continuous pseudocontractive mapping. Then for and each , there exists a sequence satisfying which converges strongly, as , to the minimum-norm fixed point of T. Moreover, we provide an explicit iteration process which converges strongly to a minimum-norm fixed point of T provided that T is Lipschitz. Applications are also included. Our theorems improve several results in this direction.

Pakistan Journal of Biological Sciences , 2003,
Abstract: The present study was conducted to compare the effectiveness of different insecticides with reference to chickpea pod damage by the larvae of Helicoverpa armigera (Hubner) during Rabi season 2001-02. Four insecticides viz. cypermethrin (10 EC) @ 350 ml acre ̄1, endosulfan (35 EC) @ 1000 ml acre ̄1, lambdacyhalothrin (2.5 EC) @ 250 ml acre ̄1 and chlorpyrifos (40 EC) @ 800 ml acre ̄1 were tested twice. The screening of best insecticide was determined by comparing treated plots with untreated plots. Chlorpyrifos proved to be the best insecticide in reducing the pod damage and hence increased biomass and yield followed by endosulfan, lambdacyhalothrin, cypermethrin. However, all the insecticide treatments proved to be better in comparison with control in all the above mentioned aspects.
