مولاناعبیداﷲ سندھی
واحسرتا! ابھی برہان کے صفحات پرمولانا محمدالیاس صاحب کاندہلوی کے ماتم میں ہمارے قلم کے آنسو خشک بھی نہیں ہونے پائے تھے کہ ۲۴؍ اگست کی صبح کو اخبارات سے معلوم ہواکہ ہماری بزم علم وعمل کاایک اور صدر نشین ہماری محفل سے رخصت ہوگیا۔یعنی مولانا عبیداﷲ سندھی نے چند روز کی علالت کے بعد پنجاب کے ایک مقام دینپور ریاست بھاولپور میں ۲۳؍اگست کووفات پائی۔اناﷲ واناالیہ راجعون۔
مولانامرحوم ۱۰؍مارچ ۱۸۷۳ء کو پنجاب کے ضلع سیالکوٹ میں ایک سکھ گھرانہ میں پیدا ہوئے۔سولہ سال کی عمر میں خوداپنے غوروخوض اورتحقیق وتلاش کے بعد اسلام قبول کیا۔ پچیس سال کی عمر میں علمِ دین کی طلب کاشوق انھیں کشاں کشاں دیوبند لے آیا۔ جہاں آپ نے چھ سات سال قیام کرکے درسِ نظامی کی تکمیل کی اور اس سے فارغ ہوکر سندھ چلے گئے۔یہاں کئی سال تک درس وتدریس میں مصروف رہے۔ایک مدت کے بعد حضرت شیخ الہندؒ نے آپ کو پھر دیوبند بلا بھیجا۔جہاں وہ اپنے شفیق استاذ کی نگرانی میں مختلف اہم اور ضروری کام انجام دیتے رہے۔اس سلسلہ میں آپ حضرت الاستاذ کے حکم سے ۱۹۱۵ء میں کابل گئے اوریہاں افغانستان کے انقلاب میں براہِ راست حصہ لیا۔ سات سال تک اس ملک میں قیام فرمانے کے بعد ۱۹۲۲ء میں آپ ماسکو آئے جہاں انقلاب کے ہاتھوں ایک نئی دنیا تعمیر ہورہی تھی۔زارکاروس ختم ہوچکا تھا اور لینن کے فیض دم سے سوویٹ روس کے خاکی پتلے میں جان پڑرہی تھی۔ مولانا مرحوم نے ان تمام حالات کاجائزہ بڑے غوروخوض سے لیا اور پھرایک سال قیام کرنے کے بعد آپ ٹرکی تشریف لے گئے۔یہ وہ زمانہ تھا کہ یہاں خلافت کے نسخ کااعلان ہوچکاتھا۔اسلامی قوانین کے بجائے سوئٹزرلینڈ کاقانون نافذ کیا جا رہا تھا۔ شیخِ اسلام کوترکی سے رخصت کردیاگیا تھا۔ عربی رسم الخط کی جگہ لاطینی رسم الخط کو رائج کیاجارہاتھا ۔غرض...
Teens and children will need to be vaccinated in order to achieve herd immunity against COVID-19. Most parents are eager to have their teens immunized, whereas some are hesitant. Should teens be allowed to consent to immunization even if their parents’ objects? Vaccines are safe and effective, medically recommended, and good for both the individual and the community. Inspite of these powerful arguments, the law lags behind. Most parents want their teens to be immunized. Most vaccine-hesitant parents ultimately agree to vaccination. Furthermore, teens who get COVID generally have mild cases. For now, the law in most states does not permit teens to consent to the COVID-19 vaccine without parental permission.
In view of the protection of Gaza coastal and marine environment from further deterioration and reverse the process from polluted to clean marine environment, it was necessary to analyse the seawater quality data and develop several artificial neural network (ANN) models to predict various water quality parameters. Hence, this study was undertaken with this objective. Even though there have been a few monitoring and evaluation literatures on the status of seawater pollution, however to the utmost of facts this work is the initial effort to use (ANN) technology for the prediction of seawater quality along Gaza coast. Additionally the land-based sources causing pollution along Gaza coastal waters have been assessed and also a management plan for Gaza coastal and marine environment protection proposed. All seawater quality monitoring data were inserted into Minitab statistical software and analysed by different tools including: min, max, mean, standard deviation and geometric mean. In addition, the Pearson correlation coefficient and paired sample t- test were used to perceive significant water quality differences at various sampling locations. The core objective of this work was to investigate whether it is possible to predict the next two weeks values of water quality parameters such as pH, electrical conductivity (EC), dissolved oxygen (DO), biological oxygen demand (BOD 5 ), Total kjeldahl nitrogen (TKN) and orthophosphate (Ortho-P). The data used was measured by several water quality monitoring programs in the Mediterranean Sea along Gaza. At the initial stage of the prediction of water quality variables, real water quality data along Gaza coast, over a period of four years beginning from 1997 to 2001, were collected from the Environment Quality Authority, the Environmental and Rural Research Centre-Islamic University of Gaza, Ministry of Health and some other organisations. The training and testing of the developed ANN assessment models was carried out using neural network toolbox in the MATLAB. Two types of feedforward networks have been used. They are Multilayer Perceptron (MLP) and Radial Basis Function (RBF) neural networks. xxiFour different MLP neural networks have been trained and developed with reference to water temperature, wind velocity and turbidity parameters to predict pH and EC fortnight’s values. MLP and RBF neural networks have been used for predicting the next fortnight’s dissolved oxygen concentrations. Both networks are trained and developed with reference to the five oceanographic variables including water temperature, wind velocity, turbidity, pH and conductivity. MLP neural network has also been trained to predict BOD 5 level. MLP and RBF neural networks have been trained with five parameters to predict nutrients (TKN and Ortho-P) level along Gaza coast. Prediction results prove that both types of networks are highly satisfactory for predicting water quality parameters in the Mediterranean Sea along Gaza coast. Results of the developed networks have also been compared with the statistical model and found that ANN predictions are better than the conventional methods. The human activities including: urbanisation in coastal areas, wastewater pollution, coastal activities, agricultural loads, industrial pollution, influence of fisheries and solid waste as well as debris exert pressure on the marine and coastal environment. All these are land-based sources causing pollution along Gaza coastal environment. In order to reduce the load of pollution in the coastal waters of Gaza, it is recommended that the Palestinian Environment Quality Authority (EQA) shall play a major and active role in implementing the Gaza coastal environmental management plan (GCEMP). Therefore, EQA shall prepare the short term and long term action plans through coordination with all the relevant stakeholders. It is hoped that ANN developed models and the proposed management plan will help in assisting the local authorities in developing plans that are necessary to minimise the sources that cause pollution along Gaza coastal waters.
