Grass carp, Ctenopharyngodon idella is one of the most popular species of aquaculture as it has ability to convert plant material into good quality protein. As feeding expenses of aquaculture is 60% of total expenses, many researchers have tried to cut down the feeding expenses of fish by using cheap and waste raw material as fish feed. In this study a comparison of growth of grass carp was made by using rice bran. Grass carp fry were obtained from hatchery and these were kept in steel tanks for 15 days for acclimatization to experimental conditions before start of experiment. During this period they were given mixture of fish meal and rice bran in 30% and 35% proportion. Experiment was conducted using three types of diets. One simple fish meal, second fish meal and 30%rice bran and third a mixture of fish meal and 35% rice bran. These diets were available to the three groups of fish round the clock. Growth was checked by netting 50% or more than 50% of fish from each tank. Fish were weighed in bulk every fortnight. After every sampling 50% water in each tank was replaced with fresh water. Following parameters were checked (1) mean weight increase, (2) body weight gain (3) specific growth rate. At the end of experiment fish from three groups were killed and their body composition was checked for water, % protein % fat, % organic content wet and dry. According to results fish meal with 35% rice bran gave maximum growth in fish.

تقریظِ اول

تقریظ اول
حافظ محمد اکرم راشد کا تعلق ایک علمی گھرانے سے ہے اور اپنی وراثت کو جو علم کی صورت انھیں اپنے آبا ئواجداد سے ورثے میںملی ہے، تشنگانِ علم کو منتقل کرنے کے لیے ہمیشہ مستعد رہتے ہیں۔ موصوف عارف والا کی ایک مرکزی مسجد میں خطابت کے فرائض سر انجام دے رہے ہیں۔اِن کا تحریری کام مختلف جرائد میں گاہے بگاہے چھپتا رہتا ہے۔
زیرِ نظر کتاب’’ نسیم سخن‘‘جو تقاریر کا مجموعہ ہے یہ ایک عظیم کام ہے۔ آپ کی ایک اور کتاب قبل ازیں ’’نگارشاتِ راشد‘‘ کے نام سے زیورِ طباعت سے سے مزین ہو کر منظرِ عام پر آچکی ہے۔ آپ نے انتہائی محنت ،لگن اور خدمتِ خلق کے جذبے سے سرشار ہو کرنسیم سخن (جو تقریروں کا مجموعہ ہے) کو عوام الناس کے لیے باالعموم اور طلبا کے لیے بالخصوص مدون کیا۔ تقریباً تقریروں کا یہ مجموعہ فی البدیہہ تحریروں پر مشتمل ہے جو موصوف کی کی اس فن سے کما حقہ آگہی پر شاہدہے۔ ان میں سے اکثر تقریریں گزشتہ دور میں انعقاد پذیر ہونے والے سرکاری سطح کے مقابلہ جات میں پوزیشنیں حاصل کر چکی ہیں۔اللہ تعالیٰ ان کی اس کاوش کو قبول فرمائے۔

امن کے حوالہ سے اسلام پر کئے جانے والے اعتراضات و شبہات کا جائزہ

In the present age, a great conflict has become the source of clash between Islām and the rest of the world, especially, the western world. The world of Islām is accused of having and breeding the fanatical elements, who help promote terrorism in the world. The Western world and the media leave no opportunity to malign the name of the most peaceful religion of the world. This article illumines that Islām is a peace loving religion and does not approve terrorism. Those elements, involved in disrupting peace are not the true representative of Islām. They make a very minor portion of the Islamic world. The majority of Muslims are peace loving people and they need to be given a due coverage by the media. This research article is an attempt to present a very soft, peaceful and noble image of Islām before the world, especially, the western world. The two main sources of Islām: al-Qur’ān and the sayings of the Prophet of Islām, the prophet Muḥammadﷺ, have been quoted extensively, to prove that the religion and the meanings of the world, ‘Islām’, all reflect peace, fraternity, friendship and altruism. The Western scholars have also been quoted appropriately to support the said premise.

Environmental Risk Factors of Tuberculosis and Detection of Infection and Drug Resistance Through Multiplex Analysis

Over 9 million new active tuberculosis (TB) cases emerge each year from an enormous pool of 2 billion individuals latently infected with Mycobacterium tuberculosis (M. tb.) worldwide. About 3 million new TB cases per year go undiagnosed, and 1.5 million die (equivalent to AIDS related deaths). Involvement of various host related and environmental risk factors increasing the susceptibility of the disease and emergence of MDRTB has made the control and eradication of the disease difficult. TB, however, is generally curable if diagnosed correctly and in a timely manner. The current diagnostic methods for TB and MDRTB, including state-of-the-art molecular tests, have failed in delivering the capacity needed to curtail this ongoing pandemic. Highly efficient, accurate, cost effective and scalable diagnostic tests are critically needed. We report a multiplex TB serodiagnostic panel for TB infection and a DNA based tests for MDRTB, based on microbead suspension array. Our serodiagnostic panel demonstrates sensitivity of 91% for confirmed TB cases on serum/plasma samples from patients. Sensitivities of this new test format for sputum smear positive and negative cases are 95%, and 89%, respectively, and this test has specificity of 96%. Similarly our DNA based test for MDRTB mutation has 86% sensitivity for Rifampicin, 92% for Isoniazid, 62% for Streptomycin and 63% for Ethambutol resistant samples. This test has shown 100% specificity and 100% correlation between sputum and culture samples of MDRTB. These diagnostic criteria for the multiplex TB & MDRTB test are greatly superior to that of the frontline sputum smear test (30-70% sensitivity) and conventional culture and DST. The test can be run on either blood plasma/serum or dried blood spots (DBS) for TB infection and on DNA isolated from sputum/culture of MDRTB sample, enabling use in almost any setting with scalability from 1 to 360 patients per day, and is amenable to automation for higher (1000s per day) throughput. We also have reported the involvement of well-established host related, environmental and social risk factors in susceptibility of the disease. For host-related factors, TB was found to be significantly associated with male gender, marital status, smoking, drinking, personal and family history of TB, asthma and diabetes (OR: 1.08, 1.96, 1.21, 4.26, 2.07, 3.16, 3.43 and 3.67) respectively with P-value <0.001. For environmental and socio economic factors TB was found to be associated with adult crowding, increased family size, poor ventilation and use of biofuels (OR: 4.60, 1.75, 3.29 and 3.90) illiteracy, unawareness of the disease, migration and presence of animals in the house (OR: 1.74, 0.07, 1.83 and 1.60) respectively with p-values of <0.005. Thus in combination with information of demographic details, risk factors information and use of the proposed test, diagnosis of TB and MDRTB can be possible in one day without any delay in initiation of the treatment. This approach can help TB control program to control the disease by diagnosing it efficiently, accurately, and timely.
