OS is set of activities which enables a user or group of users to make utilization of system resources. Multiprogramming OS runs several jobs concurrently. The aim of the multiprogramming is to use the system resources optimally. Optimal resource utilization can be attained by effective and efficient sharing of resources between several users and jobs. Optimal resource allocation relies on effective and well-organized job scheduling at the processor. Job scheduling is a main part of multiprogramming OS. Since the processor is the main essential resource, job/processes scheduling also known as CPU scheduling, develop into one of the core components of OS. CPU Scheduling plays a very important function in efficient and effective use of resources. Various algorithms have been suggested for implementation of CPU scheduling to attain the optimality in OS. Our research work introduces new CPU scheduling algorithm with the high degree objective of optimality in effectiveness and performance. This research work compares the suggested new CPU scheduling algorithm with the existing classical algorithms and recently published ones. Simulation is used for the relative performance study of various CPU scheduling algorithms using synthetic workload. The results of simulations are in form of scheduling performance metrics as per the standard practices followed by the scientists of OS. The simulation may also be used for the guidance and exercise of students of OS.

۴۶۔ آخر کیا ہے زندگی؟

آخرکیا ہے زندگی؟

زندگی پر یہ بے لاگ تبصرے

وقت کے ضیاع کے سوا کچھ نہیں

 زندگی کا سراغ کسے ملا ہے

ہر کسی کو زندگی سے گلہ ہے

یہ کیوں اور کس لیے ملی؟

 مورِ ناتواں کے سکڑتے پیٹ کی صدا ہے زندگی؟

 بیلوں کی بھوک سے نکلی پسلیوں کی نوا ہے زندگی؟

 سنگ و خشت اٹھائے مزدوروں کی ندا ہے زندگی؟    

 تخت پہ بیٹھے شیروں کی عیش کا نام ہے زندگی؟

اسلام کا تصور تعلیم و تربیت

Education has been considered of primary importance in human life. Religion and education are interrelated. A civilized society requires educational revolution in behavior of human beings. Education creates awareness about the human goals and real aim of life. This activity makes it possible to train the people in the right direction. Better education coupled with proper training makes a human being well-mannered and enables him to use his hidden qualities for the benefit of mankind, thus making him a beneficial not only for himself but also for the society. The preaching of religion depends upon the education and training. Our holy Prophet ﷺ was an ideal educationist not only of his time but also for the future generations. The Holy Prophet ﷺ being a great educationist and reformer initiated the University of Suffa in Medina when the Islamic society was in its infancy. Prophet ﷺ described the conditions, pattern and qualities of a teacher. A good teacher must be interpreted as good practitioner as well. The article deals with the moral qualities of a teacher and educationist in the light of teachings of the Prophet Muhammad ﷺ. The discussion has made clear the aim of Islamic education which is not limited within the domain of worship or prayers. Islam is a complete code of life which emphasizes the training of human being through education.

Quantification of Residual Antibiotics in Pharmaceutical Effluents Affected Areas and Their Removal by Using Nanotechnology

Contamination level of antibiotics namely ofloxacin (OFL), ciprofloxacin (CIP), levofloxacin (LEV), oxytetracycline (OXT) and doxycycline (DOX) were quantified in wastewater, soil, plants and underground water of areas surrounding pharmaceutical industry in Lahore. HPLC with DAD detector, C-18 column and solid phase cartridges were used to analyze antibiotic residues. In wastewater CIP was 3.0-5.25 mg/L, LEV was 0-6.20 mg/L, OFL was 2.45-4.12 mg/L, OXT was 0-9.40 mg/L, and DOX was 1.58-6.75 mg/L. From wastewater antibiotics accumulate in environmental segments and impact human health. From wastewater antibiotics accumulate in soil and plants and percolate to groundwater. The contamination level was 1000 times higher in wastewater samples than other samples, as it is the primary source of antibiotics entering environment. After wastewater, soil was the most contaminated environmental segment and ground water was the least contaminated by these residues but water is very important as it is source of accumulation of antibiotics to human and animal body as well as to plants. Drinking water is most essential thing for life on earth. Due to environmental pollution day by day the quality of drinking water is deteriorating. Ground water is being contaminated due to industrial pollution. In groundwater DOX has highest mean level of contamination and OFL was determined as highest contaminating pollutant in soil. Highest detected value in groundwater of OFL was 0.50, CIP and LEV 0.20, DOX 0.80 and OTC 0.40 ng/L. Ground water has residual level of CIP 0.01-0.20 ng/L, LEV 0.02-0.20 ng/L, OFL 0.01-0.50 ng/L, OTC 0.02-0.40 ng/L, and DOX 0.04-0.80 ng/L. Soil and vegetables are the most integral environmental segments for human and animal life. Day by day both of these segments are becoming polluted by anthropogenic resources and one of the major sources of contamination is pharmaceutical wastewater entering environment. Contamination level of OFL, CIP, LEV, OTC and DOX were determined (found) in vegetables samples in areas surrounding pharmaceutical industry. HPLC with DAD detector, C-18 column and solid phase cartridges were used to extract and analyze antibiotic residues in carrot, wheat and spinach samples. In wheat samples LEV and in spinach and carrot samples OFL was detected as highest accumulated antibiotic among five antibiotics selected. In all types of vegetables samples the contamination of each antibiotic was highest in leaves and lowest in fruits. The order of accumulation was leaves > stem / shoot > root > fruit. The contamination level was higher in soil samples than vegetables samples. From soil antibiotics accumulate in plants and vegetables, and leach to groundwater. Plants and vegetables directly or indirectly are a part of human food. The most appropriate method to stop antibiotic pollution in environmental segments is to remove or eliminate these pollutants at source. For such treatment of wastewater containing antibiotics, six photocatalyst P-I, P-II, P-III, P-IV, P-V, P-VI obtained by doping of Cr, Co, and V, were used to degrade 25 ppm, 50 ppm and 100 ppm sample solutions of CIP, LEV, OFL, DOX and OXT. After 30 min, 60 min, 90 min and 120 min time period of addition of photocatalysts these samples solution were analyzed for the degradation efficacy of photocatalyst. The degradation of these antibiotics was observed for variation in parameter like pH of the solution, time of exposure to sunlight, temperature of the solution and amount of the photocatalyst added in the solution.
