پہلی گل
پاکستان ایئر فورس دی ملازمت دے دور ان رسالپور اکیڈمی دے وچ جس ویلے میں ایم۔اے پنجابی کیتا تے دل وچ ہک کرلاٹ پے گئی۔کیوں کہ پنجابی ادب بندے نوں ورثے وچ ملیا سی۔والد صاحب حافظ قرآن تے درویش منش آدمی سن۔تے پنجابی دیاں کتاباں ،ہیر وارث شاہ،سسی پنوں،یوسف زلیخا،مولوی غلام رسول،کافیاں بُلھے شاہ،کافیاں شاہ حسین،سی حرفی سلطان باہو تے بوٹے گجراتی دیاں سی حرفیاں،تے دائم اقبال دائم دی کتاب سیف الملوک وغیرہ پہلے ہی گھر وچ مو جود سن۔ایس واسطے زیادہ تر سی حرفیاںتے بارہ ماہ ۱۹۹۴ئ،۱۹۹۵ء وچ ای لکھے گئے۔
وقت گزر دار ہیا تے ۲۰۱۸ء وچ بندے نیں ایم۔فل اردو کیتا تے اردو ،پنجابی وچ لکھن دا شوق پیدا ہویا۔بقول وارث شاہ:
’’بجھی عشق دی اگ نوں وا لگی،سماں آیا ای شوق جگاونے دا ‘‘
پنجابی غزلاں زیادہ تر ۲۰۱۸ تے ۲۰۱۹ وچ لکھیا ں گئیاں۔کتاب دا ناں’’دکھاں دی پنڈ ‘‘میرے اپنے ذہن دی پیداوار اے۔دنیاں دُکھّاں تے مصیبتاں دا گھر اے۔دنیا تے بھانویں کوئی جیڈا وی سکھی ہووے ،کوئی نہ کوئیدکھ ہر اک نوں ضرور ہوندا اے۔سیانے آکھدے نیں’’دکھاں توں بعد ای سکھ ملدے نیں‘‘۔جے دھپ ہے تے چھاں ہے،جے رات ہے تے دن ہے،جے ہنیرا ہے تے چانن ہے۔پھل بڑے نازک تے خوشبوواں دیون والے ہوندے نیں پر کنڈیاں توں خالی نہیں ۔ایس واسطے سکھاں دا صواد وی دکھاں توں بعد ہی اوندا اے۔
’’یار میرا جے دکھ وچ راضی، میں سکھ نوں چلھے پاواں‘‘
جے بندے نوں کوئی وی دکھ نہ ہووے تے وقتِ نزع تاں گیا ہی کدائیں نہیں۔
ساڈے با بے آدم نوں رب نے جنت وچوں کڈھ کے تے زمین تے چا سٹیا۔گویا جنت وچوں نکل کے ہک قسم دے دوزخ وچ آ گئے،تے نال ہی’’دکھاں دی پنڈ ‘‘سر تے آ گئی۔اﷲ پاک نے اپنے ساریاں پیاریاں پیغمبراں نوں دکھ دے کے آزمایا۔وصل دیاں لذتاں وی ہجر فراق...
Temporary pools are relatively small water bodies with limited resources and are seasonally available. These freshwater bodies are rich source of microbial and planktonic lifeObjective: This survey was conducted to find out the presence of rotifers in temporary pools formed inJallo Park established in 1978 and explore their density and diversityMethods: Sample collection was done from ten pools with the help of a planktonic mesh. The counting was performed with a Sedgwick- Rafter chamber. Diversity indices like Shannon Weaver index etc. Were applied Results: In present study 27 rotifer species belonging to 14 genera were identified. The highest diversity and density was shown by Brachionus and Lecane. There was even distribution in each pool. Results of ANOVA showed statistically significant difference in population density and diversityConclusions: This study has presented a guideline to find out rotifer diversity which could be present in any water reservoir like temporary pool.
The aim of the present research work is to synthesize flexible polymer based nanocomposites with excellent dielectric properties. Compounds and composites with high dielectric constant are in demand in electronic industry due to their ability to store more charge, while energy dissipation is low there. So it is needed to synthesize materials with ability to store more and more charge. In presented research work, flexible three phase nanocomposite films of graphene/metal/polymer were synthesized with reasonably high dielectric constant or real part of permittivity and very low dielectric loss or imaginary part of permittivity. Ternary nanocomposite films were synthesized by using three different polymers i.e., poly(vinyl alcohol), polyvinylidene fluoride and polydimethysiloxane as matrix. Graphene and two ceramic metals oxides i.e., titania and barium titanate were reinforced in the polymers as conducting and metal additives, respectively. In this way six different types of ternary nanocomposite films with different combinations of fillers and polymers were synthesized. Each ternary nanocomposite series was synthesized by varying w/w of graphene while keeping concentrations of ceramic and polymer constant. After setting optimized conditions for concentrations of graphene, w/w of ceramic filler was varied and concentrations of ceramic and polymer were kept fixed. Each ternary graphene/metal/polymer nanocomposite film was characterized by scanning electron microscopy, X-ray diffraction analysis, raman spectroscopy, fourier transform infrared spectroscopy and thermal gravimetrical analysis to study their morphology, structures, presence of functional groups and thermal stability respectively. Dielectric characterization of each ternary graphene/metal/polymer nanocomposite film was carried out at room temperature. Ternary nanocomposite with highest dielectric constant and lowest dielectric loss were explored for each ternary nanocomposites series. Dielectric constant of poly(vinyl alcohol), Polyvinylidene fluoride and polydimethysiloxane was increased from 13.3, 20.5 and 6.5 to 330, 159.8 and 108.3, respectively, with addition of graphene and titania. While dielectric constant of poly(vinyl alcohol), Polyvinylidene fluoride and polydimethysiloxane was increased from 13.3, 20.5 and 6.5 to 66, 199.9 and 116.9, respectively, with addition of graphene and barium titanate. Even with such high dielectric constant, dielectric loss of all ternary nanocomposites was still very low i.e., less than 5 which is required for energy storage devices. AC conductivity and complex electric modulus of all neat polymers and ternary graphene/metal/polymer nanocomposite films were also calculated and compared. The superiority of this method is that synthesized three phase graphene/ceramic/polymer nanocomposite films have hybrid properties like high dielectric permittivity and low dielectric loss of fillers and flexibility and mechanical strength of polymers. All analyses of graphene/metal/polymer nanocomposite films confirm their excellent capacitive performance. On the basis of results it is concluded that synthesized ternary graphene/metal/polymer nanocomposite films are fairly good candidate to be used as dielectric medium in energy storage devices like capacitors.
