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.

گالی گلوچ( زبان کا غلط استعمال)

زبان کا غلط استعمال
اللہ تعالیٰ خالق ہے اور بقیہ تمام کائنات مخلوق ہے، کوئی فلکی مخلوق ہے، کوئی ارضی مخلوق ہے، کوئی فضائی مخلوق ہے ،مخلوق کا دائرہ کار وسیع ہے لیکن ان جملہ مخلوقات میں اشرف المخلوقات کا تاج اللہ تعالیٰ نے انسان کے سر پر سجایا ہے۔ انسان کو عظمت و رفعت بخشی، انسان کو بلندیوں کی معراج پر پہنچایا۔ اس کا سبب گوشت پوست نہیں تھا، اس کی وجوہات نفاست ولطافت نہیں تھیں۔ یہ اعزاز لحیم اور شحیم ہونے کی بناء پر ودیعت نہیں کیا گیا تھا۔ اس اعزاز کا سبب زبان بنی جواس کو دیگر مخلوقات سے متاثر کرتی ہے۔
انسان زبان سے تلاوت کرتا ہے، زبان سے نعت پڑھتا ہے، زبان سے راہ و ہدایت کی ترجمانی کرتا ہے۔ زبان سے کلمہ پڑھتا ہے، زبان سے اسلام کی تبلیغ کرتا ہے، زبان سے صداقت و دیانت کا اظہار کرتا ہے، انسان کی یہ صفات اسے حقیقت شناس انسان بنا دیتی ہیں، انسان کو معاشرے کے لیے انعام بنا دیتا ہے، اس کی عظمت کو چار چاند لگا دیتی ہے، یہاں تک کہ انسان کوفرشتوں سے بھی عظیم بنادیتی ہے۔ بقول حالیؔ:
فرشتے سے بہتر ہے انسان بننا
مگر اس میں پڑتی ہے محنت زیادہ
اللہ تعالیٰ نے قرآن پاک ِمیں ارشاد فرمایا کہ ’’لوگوں سے اچھے طریقے سے گفتگو کرو‘‘ قرآنِ پاک میں جس طرح نماز کے بارے میں حکم ہے، جس طرح زکوٰۃ کے بارے میں ارشادِ باری تعالیٰ ہے، جس طرح روزوں کے بارے میں حکمِ ربّانی ہے، بالکل اسی طرح زبان کے استعمال کا بھی ذکر ہے، نماز، روزہ، حج، زکوٰۃ اور دیگر عبادات کی بجا آوری سے جس طرح انسان کی زندگی میں نکھار آتا ہے اسی طرح زبان کے صحیح استعمال سے بھی اس کے جملہ لمحات ِزیست مرصعّ ومزیّن ہوجاتے ہیں، اور وہ اپنی زندگی...

Optimization of Svm for Sentiment Analysis

The growth of user?s generated contents increased exponentially onthe microblogging platforms like Facebook, Twitter and Blogger in the form of comments and opinions. This bulk of helpful data is difficult to analyse and also a time consuming task. So,an intelligent text mining system that can automatically analyse and categorise such vast user generated data is needed. Due to the noisiness in data, it is difficult to design such a processing technique because of spelling mistakes, grammatical errorsand improper punctuation. Automatic opinion extraction is a useful technique to monitor consumers'' feedback regarding any particular productsin terms of positive or negative.The management of customer relations can use these feedbacks to improve the products and services and ultimately can make the clients happy. Support Vector Machine (SVM) is one of the most famous and useful supervised machine learning technique used for sentiment classification and opinion extraction. Many extensions and modifications of this algorithm are available today. The purpose of this research is to improve the SVM accuracy through grid search technique for sentiment classificationof textual data.
