This study is titled as “A Study of Organizational Structure, Students Achievement and Physical Facilities at Public and Punjab Education Foundation Partner Schools in Punjab” The objectives of the study were to; 1) explore the organizational structure of Public and Punjab Education Foundation partner schools, 2) compare the achievement of students at Public and Punjab Education Foundation partner schools, 3) compare the physical facilities at Public and Punjab Education Foundation partner schools, 4) examine the effect of organizational structure on students achievement at Public and Punjab Education Foundation partner schools, 5) assess the effect of school physical facilities on students achievement at Public and Punjab Education Foundation partner schools, and 6) forward recommendations for the conduct of further research on the subject. To achieve the above stated objectives of this study, the following research questions were made: 1) What is the difference between organizational structure of Public and Punjab Education Foundation partner schools? 2) What is the difference between the achievement of students at Public and Punjab Education Foundation partner schools? 3) What is the difference in the physical facilities of Public and Punjab Education Foundation partner schools? 4) What is the effect of organizational structure on students‟ achievement at Public and Punjab Education Foundation partner schools? 5) What is the effect of school physical facilities on students‟ achievement at Public and Punjab Education Foundation partner schools? The study was quantitative in nature. The design of the study was descriptive based on the survey of the opinions of the Head Teachers and Principals. A sample of 506 Head Teachers of Public schools and 146 Principals of Punjab Education Foundation (PEF) partner schools was drawn through multi stage random sampling technique. A self developed rating scale and checklist for gauging physical facilities (CLPF) was used as an instrument. The PEC annual results of 8th grade Public and PEF partner schools were taken as their achievement scores. The descriptives as well as inferential statistics i.e. t-test, Chi Square and Regression were computed. The predominant findings show that PEF partner schools perform better than Public schools in maximum measures of organizational structure except a few which have been picked up for this study. The performance of Public schools is better regarding students achievement as compared to PEF partner schools. The results of the study show that Public schools provided better physical facilities as compared to PEF partner schools. It could be concluded that organizational structure and physical facilities of both type of schools have direct bearing on students‟ achievement. The study recommends that 1) Highly qualified people are found at Public Schools and it necessitates the revamping of induction process to attract people in PEF partner schools alike Public schools. 2) Schooling process of PEF partner schools is better than Public schools; the same may be followed by the Public schools and PEF partner schools to go by the follow up mechanism of Public schools for the better decision making, standards for space provision, development of school congenial climate and developing job satisfaction among the staff. 3) Academics seems better at Public schools and the PEF partner schools are recommended to follow make endeavours to lesser the gap in case of urban and rural schools of Punjab Education Foundation. 4) Both types of schools are found lacking in the physical facilities like laboratory (for practicals of science subject), lifts (for disabled students), mosque (for saying prayer), transport and air conditioning (for hot season); the same put these schools under obligations to provide the earlier said facilities.

نہ خط لکھوں نہ زبانی کلام تجھ سے رہے
رہے بس اتنا شناسائی کا بھرم باقی
نہ عہدِ ترکِ تعلق، نہ قربتیں پیہم
یہی رہیں ترے نشتر، ترا طریق علاج
نظر میں عکس فشاں ہو ترے جمال کی دھوپ
اب اس سے بڑھ کے مجھے چاہیے بھی کیا آخر
خاموشیوں کا یہی انتقام تجھ سے رہے
اشارتاً ہی دعا و سلام تجھ سے رہے
بس ایک ربطِ مسلسل، مدام تجھ سے رہے
اسی طرح غمِ دل کو دوام تجھ سے رہے
دیارِ جاں میں سدا رنگِ شام تجھ سے رہے
دیارِ فن میں اگر میرا نام تجھ سے رہے

Historical Roots of Radicalization in Pashtun’s Society

This research article aims to trace the history of radical movements in the North-West frontier of sub-continent. Historically, radical movements have long roots in Pakhtun Society.  People recruited in different epochs from Pakhtun society branch into various freedom movements before the partition of sub-continent. Freedom movements against the Sikh, Hindu and the British lifted radical impact on Pakhtun Society before the partition of sub-continent.  Radical movements after the partition of sub-continent also established their roots in the North-West region of Pakistan. These radical movements engineered the pluralistic cultural values of Pakhtun Society. These movements have lifted radical trends in the North-West frontier of sub-continent. Pakhtuns and their cultural values were not only exposed to violence but the evolution of their culture had been disturbed.

Towards Second Generation Non-Aseptic Ethanol and Hydrogen Fermentations Employing Extremophiles

Biofuels obtained from first generation (1G) sugars-starch streams have been proven unsustainable as their constant consumption is not only significantly costly for commercial scale production systems but it could potentially lead to problems associated with extortionate food items for human usage. The valorization of second generation (2G) lignocellulosic biomass through bio-fermentation employing extremophiles is the strategic tool leading to sustainable process development for biofuels’ generation. In this regard, sugarcane bagasse (SCB) is a potential valuable lignocellulosic biomass, adequate enough in carbon for fermentative processes and embodying itself as waste, whose disposal is considered as burden on natural environment especially in agricultural countries like Pakistan. 2G fermentation technologies at large scale for ethanol and hydrogen productions are limited due to low reactor productivity, product titer and yield. In the present investigation, a moderate alkali-thermophilic ethanologenic bacterium was isolated from soil sampled from the vicinity of hot water effluent near Balkasar oil refinery, Chakwal, Pakistan and identified through 16S rRNA gene sequencing as Bacillus licheniformis. Consequently, it was allotted the accession No. KU886221. The isolate was found to ferment glucose and xylose thus making it a potential candidate to employ SCB for ethanologenesis. Further valuation on the ethanologenic potential of the isolate was done by using SCB pretreated with H2SO4, H3PO4, HCl and NaOH following with and without enzymatic hydrolysis in the fermentation medium. The outcome revealed that significantly elevated level of ethanol was achieved in the fermentation medium by using SCB hydrolysate (SCBH) obtained after enzymatic hydrolysis of alkaline pretreated SCB. A standard 2-factor central composite response surface design was used to estimate the optimized concentration of cellulose and hemicellulose degrading enzymes (1.024 g Cellic Ctec + 0.468 g Htec Novozymes/100 g of pretreated SCB with 1N NaOH) for breaking down alkaline pretreated SCB to maximum fermentable sugars. To economize the expenditure associated with biofuels production, the low-cost corn steep liquor (CSL), a chief by-product of corn starch processing was used as nitrogen source. It was found that 3.24 % more ethanol was produced when CSL was used in the fermentation medium substituting peptone + yeast extract. Six factors (concentration of pretreated SCB hydrolysates, CSL, sodium chloride, incubation temperature, pH and fermentation period) affecting ethanol fermentation were optimized using Taguchi OA L27 (3^13) of Design-Expert 8 software. A batch-culture was carried out under optimized conditions for ethanol fermentation in bench-scale stirred-tank bioreactor. The ethanol titer was 11.301 g/L corresponding 0.909 mol of ethanol/mol of sugars consumed with 98.5 % reduction of substrate. In terms of biomass, 0.114 g ethanol/g of alkaline pretreated SCB was obtained. Next, the fed batch fermentation was performed to understand to consequence of substrate addition on batch fermentation. Significantly improved level of ethanol was found at the end of fermentation (120 hours) i.e.16.896 g/L corresponding 0.973 mol ethanol/mol sugars consumed. In terms of biomass, 0.123 g ethanol/g of alkaline pretreated SCB was obtained at the end of fed batch fermentation experiment. Further modification in fed batch fermentation setup was done by incorporating immobilized cells fibrous-bed bioreactor (FBB) to surpass the production of ethanol under alkali-thermophilic fermentation conditions. Subsequently, improved ethanol production associating 85.031 % substrate utilization was observed with 1.076 mol ethanol/mol of sugars consumed. Ethanol titer significantly increased from 16.896 to 19.39 g/L with the attachment of FBB. In terms of biomass, 0.131 g ethanol/g of alkaline pretreated SCB was achieved at the end of fermentation. Furthermore, to alleviate the effect of ethanol induced inhibition on ethanol fermentation, the in situ gas stripping was performed during the fermentation through the culture medium. Highest ethanol titer of 21.637 g/L equivalent to 1.1406 mol ethanol/mol of sugars consumed with 94.295 % substrate consumption was obtained. In terms of biomass 0.135 g ethanol/g of alkaline pretreated SCB was obtained at the end of fed batch fermentation involving FBB and gas stripping. Finally, fed batch fermentation involving FBB was studied under non-aseptic conditions. The results demonstrated that comparing aseptic conditions, 30.5 % reduced ethanol was obtained under non-aseptic conditions showing the likelihood of some contaminant(s) in the fermentation culture. In the second part of investigation, Clostridium thermocellum DSMZ 1313, a renowned thermophilic cellulolytic bacterium was used for co-production of bioethanol and biohydrogen employing sugarcane bagasse directly as fuels’ feed. Six factors (cellulose, CSL, iron sulphate, magnesium chloride, incubation pH and period) affecting co-fermentation of bioethanol and biohydrogen were optimized using Taguchi OA experimental design. In the following experiment, cellulose was substituted with SCB pretreated with different chemicals in separate batch experiments. It was determined that SCB pretreated with 2 % H2SO4 produced significantly greater amounts of bioethanol and biohydrogen under optimized fermentation conditions in the fermentation medium. Batch fermentation in bench-scale stirred-tank bioreactor was performed under aseptic conditions by rotating the fermentation conditions elucidated by Taguchi OA favoring maximum production of both fuels. The fermentation yielded 1.027 mol of ethanol/mol of equivalent sugar with ethanol titer of 8.662 g/L and 0.775 mol of hydrogen/mol of equivalent glucose consumed with hydrogen titer of 2.97 L/L of fermentation medium at end of the experiment with 73.081 % substrate reduction. In terms of biomass, batch yields were 0.101 g ethanol/g of biomass and 34.715 mL of hydrogen/g of biomass utilized. Afterward, FBB was incorporated in the bioreactor to enhance substrate utilization. The percent substrate consumption increased to 93.837 whereas ethanol yield decreased to 0.965 mol ethanol/g of equivalent glucose consumed with ethanol titer of 10.359 g/L and hydrogen yield significantly increased to 0.857 mol hydrogen/mol of equivalent glucose consumed with hydrogen titer of 3.78 L/L of the fermentation medium. In terms of biomass, the ethanol yield was 0.0953 g ethanol and 34.78 mL hydrogen/g biomass utilized. Effect of substrate addition on batch fermentation involving FBB disclosed improved ethanol and hydrogen titer. Overall substrate consumption increased by 25.45 % for batch fermentation involving FBB. Ethanol yield of 1.034 mol/mol of equivalent glucose consumed, whereas 0.864 mol hydrogen/mol equivalent glucose consumed were found. In terms of biomass, 0.102 g ethanol and 37.928 mL hydrogen/g biomass were produced following co-fermentation by C. thermocellum DSMZ 1313. To alleviate the effect of ethanol induced inhibition, the in situ gas stripping was performed through the culture medium. The result re-confirmed the finding that glucose conversion into product could be enhanced when the inhibitory metabolite(s) were stripped from the fermentation broth. The substrate consumption improved up to 27.507 % in comparison to previous batch experimentation. Fed batch fermentation involving FBB and gas stripping produced 0.976 mol ethanol and 0.875 mol hydrogen/mol of glucose consumed. In terms of biomass, 0.096 g ethanol/g biomass with ethanol titer of 16.734 g/L and 35.09 mL hydrogen/g biomass with hydrogen titer of 6.1L/L of fermentation medium were produced at the end of fermentation. Finally, under non-aseptic conditions, fed batch fermentation involving FBB yielded 0.857 mol ethanol/mol of equivalent glucose consumed and 0.957 mol hydrogen/mol of equivalent glucose consumed. The comparison of aseptic and non-aseptic conditions revealed that ethanol fermentation decreased by 16.07 % whereas hydrogen fermentation increased up to 14.7 % in comparison with ethanol and hydrogen productions under aseptic conditions. In terms of biomass 0.084 g ethanol and 45.136 mL of hydrogen/g of biomass were produced. Principal aim of this study was to extract the energy from renewable waste sugarcane bagasse under non-aseptic extreme conditions in the form of bioethanol and biohydrogen. Successful exploitation of low cost substrate for biofuels’ production under moderate alkali/thermophilic conditions appeared promising for development of large scale bio-fermentation processes. It is foreseeable that understanding of non-aseptic extremophilic fermentations utilizing agro-industrial wastes as necessitated in the present investigation, for development of large scale cost-effective, eco-friendly biofuels generation processes will pave the way to achieve one of the greatest benefits of mankind." xml:lang="en_US
