Xylitol was produced from four indigenous agricultural by-products including sugarcane bagasse, oat hulls, mongbean hulls and peanut hulls through fermentation to evaluate potential of local agricultural wastes for xylitol production. The methodology comprised of hydrolysis followed by detoxification of hydrolysate by neutralization, concentration and charcoal treatment to remove the fermentation inhibitors. The detoxification with calcium hydroxide, five fold concentration of hydrolysate and 5% charcoal treatment at 600C was found to be probable in terms of removal of fermentation inhibitors. The resultant detoxified hydrolysate was fermented with Candida tropicalis and optimum conditions found were at pH 6.0 and temperature 300C. After refining and concentration of fermented broth, the xylitol solution was freeze dried. Highest yield of the xylitol was obtained from oat hulls followed by sugarcane bagasse, mongbean hulls and peanut hulls. The xylitol was replaced in cookies at different ratios for preparation of dietetic food product. The physicochemical, sensory and microbiological characteristics were determined at 0, 15, 30, 45 and 60 days interval. The cookies prepared with 50% replacement of sucrose with xylitol were liked by panelists. The product was found to be acceptable in view of physicochemical and microbiological parameters. Asserted health effects of the xylitol intake were evaluated through biological studies. Xylitol incorporated diet significantly affected serum glucose, cholesterol and triglycerides in normal and diabetic rats.

بِسْمِ اللّٰهِ الرَّحْمَنِ الرَّحِيمِ۔الْحَمْدُ للّٰهِ وکفیٰ وسلام علیٰ عبادہ الذین الصطفیٰ۔اما بعد:

اسلام ایک مکمل دستور زندگی اور ضابطہ حیات ہے۔ اس کے قوانین جہاں ناقابل ترمیم ہیں، وہاں ان میں حالات کی تبدیلی کے ساتھ لچک بھی پائی جاتی ہے۔ زندگی کے نئے پیش آمدہ مسائل و پیچیدگیوں کے حل کی کنجی اسلام کے پاس ہے، کیونکہ اس کے اصول ابد ی و آفاقی ہیں۔ اسلام نے معاشرے کی اخلاقی اقدار کے تحفظ کے اصول و ضوابط بیان کیے ہیں اور یہ بتلایا ہے کہ معاشرہ کی اخلاقی اقدار کاتحفظ لازم ہے۔ اگر کوئی اس کا خیال نہیں کرے گا تو معاشرہ اس کے حقوق کو تحفظ بھی فراہم نہیں کرے گا اور اس پر حد(سزا) بھی جاری کرے گا۔ دوسرا اسلام نے لوگوں کو فرائض کی ادائیگی کا حکم دیا ہے اور ان کے حقوق کی گفتگو انہی فرائض کے ضمن میں آ گئی ہے ۔ جب لوگ فرائض کی ادائیگی میں دلچسپی لیں گے تو خود بخود ان کے حقوق کا تحفظ ہوتا رہے گا۔ یہی وہ بنیادی فرق ہے جو اسلامی اور وضعی قوانین میں واضح طور پر نظر آتا ہے۔ اسی کی بنیاد پر جرم و سزا کے قوانین سامنے آتے ہیں ۔ انہی قوانین کی بنیاد پر ہی معاشرے کی اخلاقی اقدار کو محفوظ بنایا جاتا ہے۔ دنیا میں امن وسکون اسی اسلامی فلسفہ کا ہی مرہون منت ہے۔

 دین اسلام میں گناہوں سے دور رہنے اور ان سے بچنے کے ضابطے درجہ بدرجہ تفصیلاً بیان ہوئے ہیں ،لیکن پہلے تربیت کے مواقع فراہم کیے گئے ہیں ، پھر آخری درجے پر سزا کا حکم دیا گیا ہے۔ اس عملی کام کے علاوہ نظری طور پر اسلام کے بنیادی عقائد بھی انسان کی بھر پور تربیت کرتے ہیں...

غربت کے خاتمہ کے لیے ازواجِ مطہرات کی مساعی

Islam as a religion is not based on empty or futile theories. Infact it intensely educates in altering a practical approach towards ones exixtence both as an individual and or a social being. It is the only religion which lead the way towards welfare/ "Falah" and Qura Calls such people Muflihon. Falah is for both render, either it is a man or a woman. Women especially Holy Prophet's wives are never leave behind in poor's uplift and public welfare. From the very beginning of UMMAHATUL-MOMINEEN (Holy Prophet's wives) are playing vital role in social or public welfare an till in this modern era and patriarchal society, they are role model to help plebians. The Islamic values as the world knows of them today were brought to light through our last messanger (P.B.U.H), assigned with the most important task in probably the most crucial era of human history. With the injustice all over the globe and the leaders of super powers in a rift with each other to dominate the world, exhausted the most important of resouces i.e. The humanity. The divine manifiesto of the Prophet Muhammad (P.B.U.H) and the lives of wives of Holy Prophet was actually based upon justice among masses and the preservation of conflict torn humanity. The intellectual wisdom of Holy Prophet's wives in the given situation was to restore order while restoring justice based upon the reformative rule of law as depicted by the Islamic ideology. The main aim of this very importatnt initiative was to reintroduce the humanity with the most important elements such as humility, mutual respect an retoration of long forgotten code of ethics. The basic foundation of our last Prophet's wives idealogy was to uplift poor whether they are Muslims or not. They successfully ordained the resurfacing, prevalence and practice of the same code of ethics. Now days many of such examples are prevalent in the world, not as a whole yet, though to a certain extent which is holding it together. The war torn and devastated west of the medieval found its solution in applying the same Islamic rule of law in their society in late 17th century and onward. It therefore can be deduced that the same code of ethics, which can be referred to the Quran, the sacred Islamic book, possibly offers the most effective solutions in order to ensure the societal and social development in current era.

Impact of Incongruous Jail Environment on the Juvenile Prisoners in Selected Jails of Khyber Pakhtunkhwa, Pakistan.

This study titled as ―Impact of Incongruous Jail Environment on the Juvenile Prisoners in Selected Jails of Khyber Pakhtunkhwa, Pakistan‖ was conducted with the aim of evaluating the impact of an incongruous jail environment on the multiple aspects of juveniles‘ lives who are undergoing incarceration on charges of different kinds of crime. The study was carried out by using mixed methods research approach with concurrent triangulation strategy. Quantitative data was collected through an interview schedule from 132 juvenile prisoners whereas qualitative data was collected from 50 participants through in-depth interviews (IDIs), including juvenile prisoners, jail staff, probation officers and legal counsels. Quantitative data was analyzed through frequencies and percentages under the uni-variate analysis and chi-square test was applied for the association of dependent and independent variables under bi variate analysis. Qualitative data was analyzed through transcribing the data and identification of themes for interpretation. The results of the quantitative and qualitative data were compared and discussed through the proper procedure of the concurrent triangulation strategy. The findings reveal that different elements of living conditions in the jails were not satisfactory. The association of these different elements was found significant with the well-being of juveniles i.e. the availability of clean drinking water and enough water for other cleaning purposes, unsatisfactory toilet facilities, low quality and lack of proper food and diseases caused by that food. Juveniles complained of unfair attitudes of jail staff who dealt with them in a cruel and humiliating manner. There were no exclusive facilities to house the juveniles like Borstal Institution. Rather than rehabilitative treatment, juveniles faced physical punishment like beating etc. They were fearful of jail staff; experienced unhealthy and unsanitary conditions due to overcrowded jail conditions. Many juveniles had no knowledge about their rights and often did not know they could access free legal assistance from government. They experienced unhealthy and abusive behavior at the hands of jail staff and police and had to bribe jail staff to ensure access to justice agents. Furthermore, juvenile cases were tried at the adult courts where they experienced treatment like adult prisoners, including public hearing of their cases, unsatisfactory trials, and mental suffering from lengthy and costly hearing of their suits. Juveniles complained of multiple problems in view of non-existence of privileges as stated in the Juvenile Justice System Ordinance (JJSO) promulgated in 2000 in Pakistan. Juveniles endorsed that they established relations with adult prisoners and gangs at jail due to the absence of proper check and balance over the interaction of juveniles. This absence led to frankness of juveniles sharing of drugs with adult prisoners and gangs at jail; and physical and financial support to juveniles by these gangsters. Although agents of the justice system did not agree to the above mentioned situation, the jail staff contended as these were going against them. The study recommends promulgation of JJSO in letter and spirit.
