Distributed query processing includes querying big data that is stored in files and other formats, there are several approaches for query processing some of them involves query the data directly using in-situ processing and some systems involves load the data before it can be queried. The report studies the different query processing systems and concludes which systems and techniques are suitable for what type of workloads

سر ہرمان دیبر

سر ہرمان دیبر

            سر ہرمان دیبر، جنھوں نے ۹۷ سال کی عمر میں وفات پائی ہے اور جن کے قواے جسمانی و دماغی آخر وقت تک پوری تندرستی کی حالت میں رہے، ان کی کتاب ’’طویل العمری‘‘ سے متعلق حال میں دوبارہ شایع ہوئی ہے، طویل العمری کے مختلف نسخے مختلف اشخاص نے تجویز کیے، لیکن سر ہرمان دیبر کے نزدیک اس کا راز صرف تین چیزوں میں شامل ہے، اولاً جسمانی محنت و ورزش، یعنی انسان کاہل نہ ہو، بلکہ تازہ ہوا میں کافی طور پر چلتا پھرتا رہے، دوسرے یہ کہ اپنی طبیعت کو قانع رکھے، قناعت کا لازمی نتیجہ یہ ہوگا کہ فکر و مایوسی اس کے پاس نہ آئے گی اور طبیعت بشاش رہے گی، تیسری اور سب سے اہم شرط یہ ہے کہ کھانے پینے میں بے اعتدالی نہ کرے، بلکہ ہمیشہ اعتدال ملحوظ رکھے، شرائط بالا کی پابندی کے ساتھ مصنف مرحوم کا دعویٰ ہے کہ ہر شخص انہی کی سی عمر و صحت حاصل کرسکتا ہے۔ (اپریل ۱۹۲۰ء)

 

Knowledge about evidence based pharmaceutical care in medical and non-medical population of Lahore, Pakistan Evidence Based Pharmaceutical Care

Pharmaceutical care related services provided by pharmacists in the community are mainly taking patients' medication history, informing patients about use of medications, informing patients about medication storage, and provide information about drug and/or food interaction. Objective: Toevaluate the knowledge about evidence based pharmaceutical care in medical and non-medicalpopulation of Lahore, Pakistan. Methods: A sample of 100 participants was drawn by using non-convenient sampling in this cross-sectional survey. Survey was conducted within the duration of 6 months from 2nd June, 2020 to 15th December, 2020. Data was collected from participants of different universities, societies and hospitals, having age between 25-40 years, both genders without discrimination of profession. Data was analyzed using SPSS version 21.0. Qualitative data was calculated using frequencies and percentages. Results: In this study 63% medical and 37% non-medical participants respond to questionnaire. About 34% of the population had knowledge about pharmaceutical care. Almost 23%had lack of knowledge about pharmaceutical care while 43%participants did not respond. Conclusions: The knowledge about pharmaceutical care in general community is very vital and pharmacist shouldprovide knowledge and pharmaceutical care services to the patients.

Potential of Microbial Insecticides and Diatomaceous Earth Against Three Coleopterous Insect Pests of Stored Grains under Different Abiotic Conditions

Sitophilus granarius (L.), Rhyzopertha dominica (F.) and Oryzaephilus surinamensis (L.) are the damaging insect pests of cereals and their commodities and are able to cause significant losses. Current research was performed to evaluate the lethal and progeny inhibition effect of microbial-based insecticides i.e entomopathogenic fungi (EPF) Metarhizium anisopliae and Beauveria bassiana as well as bacterial based insecticides (spinetoram and abamectin) solitary andwith combination of two formulations of diatomaceous-earth (DE) against S. granarius, O. surinamensis and R. dominica. Three concentrations (1x108, 1.5x108 and 2x108 spores/kg grain) of each EPF were used while for bacterial based insecticides concentrations were 0.5, 1.0 and 1.5ppm. Similarly, for diatomaceous earth, three different doses (200, 400 and 800 ppm) of every formulation were applied. Completely Randomized Design (CRD) was used with three repetitions of all treatments. Mortality of test insects was recorded after 7, 14 and 21 days while after 60 days for post-treatment progeny build up. Each bioassay was performed at three levels of temperature (25°, 30° and 35°C) and relative humidity (r.h.; 45, 60 and 75%). Collected statistics were examined with applicable statistical methods using R-Software.The data analyses had shown diversified results regarding test insect susceptibility at different abiotic conditions. In case of Bacterial based insecticides, the response of treatment remained best at high temperature and low r.h. for all test insects. Complete control was achieved after 14 days for S. granarius and R. dominica while for O. surinamensis 100% mortality was not attained even after 21-d of exposure period. Progeny production was remained totally suppressed for S. granarius and R. dominica while in case of O. surinamensis there was significant reproduction at some abiotic conditions with maximum production at temperature of 30°C with 75% r.h. The response of-D.E against test insects was also effective and the most vulnerable species was O. surinamensis followed by S. granarius and R. dominica. It was observed that high temperature, low r.h. levels, higher dosages and long exposure periods increased the efficacy of DEs. Regarding progeny production, low temperature and high humidity remained most favourable for progeny emergence in DE-treated grains. The effects of EPF remained somewhat similar to the response of DE but overall mortality was low. Among tested species of insects R. dominica remained most susceptible to the application of EPF followed by O. surinamensis and S. granarius. The best abiotic condition for B. bassiana was low temperature (25°C) and moderate (60%) humidity while for M. anisopliae moderate temperature (30°C) and moderate (60%) humidity remained suitable at which maximum response was attained. Long exposure intervals and higher dose rates increased the mortality in each case. In the case of progeny development, the emergence of offspring was suppressed at moderate and low temperature for M. anisopliae and B. bassiana respectively with moderate r.h. When DE was applied in combination with the microbial insecticides, a synergistic effect was noticed in all combinations and R. dominica and S. granarius remained more susceptible as compared to O. surinamensis. The response of abiotic condition was significant for combination of DE and EPF while for DE and bacterial based insecticide it was non-significant. The results of the study divulge that all applied microbial based insecticides and DE are very effective for the control of these test insects and different abiotic conditions are responsible for affecting their efficacy. Furthermore, the combinations of these microbial insecticides with DE have a synergistic response against test insects. This study also recommends that attention should be paid to the interaction of abiotic factors with the efficacy of DE and microbial insecticides before planning IPM strategy for stored grain insect pests.
