50سالہ تاریخ
پاکستان پیپلز پارٹی کی 50سالہ تاریخ کا جائزہ لیا جائے تو خون اور آنسوئوں سے لکھی لازوال قربانیوں اور جدو جہد کا سفر ہے کہیں خود سوزیاں کر نے والے پروانوں کے جھلستے جسموں سے بھٹو کو رہا کرو کی صدائیں گونجتی نظر آئیں گی تو کہیں دار کی خشک ٹہنی پر لٹکتے چومتے پھانسی کے پھندوں میں سے نعرہ مستانہ جیوے جیوے بھٹو جیوے بلند ہو تا ہے ۔
ننگی پیٹھوں پر کوڑے کی جھنکار سے کمر سے رستے خون سے جب تک سورج چاند رہے گا بھٹو تیرا نام رہے گا۔غرض عشق بھٹو سر چڑھ کے بولتا ہے ۔پاکستان پیپلز پارٹی کی تاریخ میں دیکھا تو یہ صرف انفرادی طور پر کارکنوںکی جدوجہد نہیں تھی اس تحریک میںکہیں ڈاکٹر زبیدہ ملک ،کامریڈ رفیع ملک مرحوم (فیصل آ باد )ماں بیٹا دونوں شاہی قلعہ کے عقوبت خانے میں لائے جاتے ہیں تو کہیں کامریڈ شاہدہ جبین اپنے بھائی عثمان غنی شہید کے ساتھ جیلیں کاٹتی نظر آتی ہیں ۔کوٹ لکھپت جیل کے ایک احاطے میں کامریڈ طلعت جعفری قید ہیں تو دوسری طرف ان کے والد محترم فضل الہی شکیل ۔اس طرح ڈسکہ سیالکوٹ کے سید سلیم عباس اور ان بزرگوار بڑے شاہ جی ۔آصف بٹ ایڈووکیٹ اپنے بھائی ناصر بٹ کے ساتھ قید کا عذاب جھیلتے ہیں ۔فیصل آباد کے محمد اعظم بٹ اور پرویز اعظم بٹ دونوں بھائیوں نے بھی برابر قیدو بند کی صعوبتیں برداشت کیں ۔جنرل ضیاء کا ظالمانہ دور ایک سے بڑھ کر ایک ظلم کی داستان ہے لیکن ان سب میں ایک عشق بھٹو میں قربان کر دیا۔جی ہاں لاہور کے آغا برداران مارشل لاء کے شروع ہی سے ان کا گھر پاکستان پیپلز پارٹی کا گڑھ تھا ۔ایک نہیں دو نہیں تین نہیں آدھ درجن سے زائد بھا ئی بہنیں...
Numerous crimes are being committed in present era. One of the most heinous crime amongst them is child abuse. Incidents of children who have been murdered after sexual abuse are rife in our nominal Islamic society. Moreover, videos and photos are also made during child abuse. Then these videos are posted on the social media. Both Muslim and non-Muslim communities are suffering from this brutal act i.e child abuse. In Pakistan, the reasons of increase in crime rates include psychological disorders, urge to fulfill one’s sexual desires, poverty, unemployment and detachment from religion. Such kind of abominable acts are becoming common in Pakistan day by day. According to Islamic jurisprudence rape is a punishable crime. Holy Prophet Muhammad (SAW) himself has punished the perpetrators for such acts of crime. Once in the era of Holy Prophet (SAW), a Jew crushed the head of a girl by placing it in between two stones. When Prophet (SAW) was informed about the incident, He (SAW) called upon the Jew who confessed his crime. Then Prophet (SAW) asked his companions to punish him by crushing his head with stones. It can be deduced from this narration that the culprits involved in such loathsome crimes should be punished publicly in order to wipe out this devilish act of crime from the society. The purpose of writing this research paper is to describe the reasons for the increase in rate of sexual abuse of children and its eradication in the light of Fiqh ul Seerah. This research paper followed descriptive and analytical methods
The expected worldwide market for membrane separation technologies is estimated to be $16 billion by the year 2017 because of extensive acceptance of the membrane technology in several end-user markets. With the increase in demand for high-quality products, environmental concerns, stringent regulations and exhausting natural resources, membrane separation technologies are predicted to see substantial development in the future. The scope of membrane technology likely is expected to be interesting as new membrane materials, innovations and processes make their way to the marketplace. The recent development in industrial applications of membrane gas separation is: to develop robust membranes, which show higher separation capacity, and are consistent and durable for specific applications. Process simulation is a method to optimize the design and operating conditions in the process. A process configuration and optimum operating conditions result in enhanced separation performance and are less expensive. In addition, with the growth of new process models, new membrane applications are arising. This study focuses on emerging models that can be used to bring improvement in the operation and design of membrane gas separation processes. Numerical models for the better performance of gas separation with high permeation were developed and verified. The pressure gradient on both sides of the membrane in different flow patterns has been considered i.e. co-current, cross and counter current. The numerical models are useful as they need least computational effort and deliver better solution stability. The robustness and the predictions of the numerical models were verified with experimental data for different membrane systems with different flow patterns. The numerical models were applied to several case studies to investigate the performance of different membrane module configurations. The research shows that the new numerical models can effectively handle the high permeate membrane problems with various flow configurations. It is a common perception that working at higher pressures permeates more gasses, and hence, occasionally the membrane module is analyzed or characterized at lower pressures to save gas utilization. It is also believed that membrane ability of gas separation declines at higher feed pressures. The obvious and key permeances of different grasses for different membranes were assessed from numerical analysis based pure gas permeation experiments reported in the ii literature. It was found that the membrane performs near to its real separation capability if it is worked at high feed pressures. The effect of pressure on the membrane performance is minimized under some special conditions. One of the most powerful features of the ASPEN HYSYS program enables users to add additional unit operations to the program through Extensibility. Using this capability, the ASPEN HYSYS could be customized for the simulations to match specific operating conditions. The built in unit operation of membrane is not available in ASPEN HYSYS. In this research, a membrane extension has been developed in ASPEN HYSYS. Developing and implementing the successful Extensions for ASPEN HYSYS requires a good understanding of the ASPEN HYSYS program, an object-oriented programming language (Visual Basic), and the purpose of the Extension. This research will help combine the knowledge of all three areas and allow us to create useful and powerful extensions for the ASPEN HYSYS program. This extension allows ASPEN HYSYS to simulate the industry specific membrane based separation processes. Computational fluid dynamics (CFD) simulations were carried out for the separation of gasses using membranes. This CFD code was used to examine the flow profile for gas separation in a membrane. To the best of our knowledge, the availability of CFD simulation on membrane gas separation is found to be limited, hence, it was attempted in the present study. The aim of this research is to use commercial CFD simulation package ANSYS FLUENT to predict flow conditions and gas permeation. For CFD calculations, the commercial solver based on finite volume method (FVM) has been used and the mass transfer through the membrane has been modeled by user-defined functions (UDFs). Two key aspects are significant for the design of membrane modules used for gas permeation. These aspects include flow distribution and concentration polarization. The later causes a reduced driving force, considerably affecting membrane performance. A uniform flow distribution will ensure that the complete membrane area is utilized. In order to reduce the influence of concentration polarization and to ensure an even flow distribution, baffles located between two membrane surfaces or plates containing flow channels are employed. Turbulence model has been integrated into the solution of incompressible flow equations.
