In this study, I focused on the isolation of phosphate solubilizing bacteria from rocks of Murree, lower Himalaya, Pakistan. Bacteria from outer and inner surface of the rocks were screened for their ability to solubilize phosphate. Three strains of bacteria were selected on the basis of halozone formation in National Botanical Research Institute for Phosphate medium (NBRIP) supplemented with TCP (tribasic calcium phosphate). The solubilization index for these bacteria was recorded as 4.29, 4.03 and 3.99. pH of the medium also dropped from the initial 7.0 to 4.0 units after 5 days of growth in liquid NBRIP medium with continuous shaking at 150 rpm. The strain P26 which is closely related to Pseudomonas species and identified as Pseudomonas putida strain (KT004384) showed maximum solubilizing activity in the given medium (161.70 mg/L) after 3 days of incubation. The other two strains P4 and N27 were identified as Pseudomonas grimontii (KT223621) and Alcaligenes faecalis (KT004385). The capability of solubilizing inorganic phosphate by these strains is attributed to the production of organic acids. The presence of these organic acids is determined by high performance liquid chromatography. Three different type of acids, gluconic, oxalic and malic acid were the dominant acids found in the culture medium. This was the first report on phosphate solubilizing (PSB) strains isolated from the rocks of lower Himalaya range Pakistan. It may be assumed that these bacteria can play a role in weathering of rocks as well.

ورفعنا لک ذکرک

ورفعنا لک ذکرک
نصیر احمد اخترؔ
نعت وہ لفظ ہے جو اردو ادب میںمحبوبِؐ خدا کی توصیف و ثنا کے لیے مختص ہے۔
نعت کے سلسلے میں پروفیسر ریاض احمد قادر ی کے خوب صورت الفاظ ہیں :
’’نعتِ رسولِؐ مقبول درود شریف کی شعری صورت ہے۔‘‘
نعت کے بارے میں ممتاز حسین کی رائے یوں ہے:
’’ہر وہ شے نعت ہے جس کا تاثر ہمیں حضورِ ؐرحمۃ للعالمیں کی ذات گرامی سے قریب لائے‘‘
’’ورفعناکی صدا ‘‘ میں اس عظیم ہستی کے اوصافِ حمیدہ بیان کیے گئے ہیں جن کی توصیف میںخود ربِ کائنات نے فرمایا’’ورفعنا لک ذکرک‘‘۔محبوبؐ خدا کا ذکر،چاہے درود کی صورت میں ہو یا نعت کی ،دراصل ورفعنالک ذکرک کی تفصیل ہے ۔
نعت کسبی نہیں وہبی ہے۔نعت کا شعر اس وقت ہی زبان کو معطر کرتا ہے جب دل حبِ مصطفیؐ سے لبریز ہو۔محمد عرفان علی خوش نصیب ہیں کہ ان کا نام بھی مقصودِ کائنات کے ثناخواں اور ثنا گو کی فہرست میں شامل ہے۔ خوب صورت شخصیت کے مالک ،عشقِ مصطفیؐ سے مالا مال ہیں۔نعت کی سعادت خدا کی خاص عطا ہے۔ اس لطف و کرم کے بارے میں محترم طالب حسین کوثری نے کہا ہے۔
ہر سخنور کو کہاں ہوتی ہے توفیقِ ثنا
ہاں مگر جس پر خصوصی ہو نِگاہِ مصطفیؐ
نعت کے لوازمات میں سے محبوبِؐ خدا سے والہانہ محبت بنیادی حیثیت رکھتی ہے۔جو شاعر جتنارسول ؐ خدا کی محبت سے سرشار ہو گا۔اس کے کلام میں اتنا ہی سرور و کیف زیادہ ہو گا۔جناب محمدعرفانؔ علی کی نعتوں میں جو کیف و سرور نظر آرہا ہے وہ محبت ِمصطفیؐ کا ہی ثمرہے۔ان کے دل میں آپؐ سے والہانہ محبت کا جذبہ پوری آب و تاب سے کار فرما ہے ۔یہ خاص نعمت ایک تو خدا کی دین ہے دوسرا ان کے والدِ محترم محمد حسین صاحب بھی...

The meters and rhythm of any poetry have great impact on the minds and souls of human beings، Maḥmūd sᾱmī al-Bᾱrūdī is one of those poets who have attracted the people through their poetry، and he has brought back the ancient meters and rhythm to the modern poetry، and chose the appropriate meters and rhythm for the subjects of his poetry. In this article we have tried to study and calculate statistically the meters and rhythm of his poetry to know the beauty and relevance of the meters and rhythm with his poetry.

A Study of Job Satisfaction of Academic and Administrative Staff Working in the Elementary Education System of Punjab

Thesis Title: A Study of Job Satisfaction of Academic and Administrative Staff working in Elementary Education System of the Punjab Job satisfaction of academic and administrative staff of elementary education is very vital because teaching and administration at elementary level is venerated and sensitive job. Job satisfaction has been a question mark and in debate by the researchers since long. It gained much importance due to its significance for the achievement of objectives of any organization. The purpose of this study was to explore job satisfaction of academic and administrative staff working in the Elementary Education System of Punjab. The respondents for this study were academic and administrative staff taken of two Districts of Punjab i.e. Sahiwal and Rawalpindi. The overall response rate was 88%. Fifty seven Assistant Education Officers, 261 Headmasters, and 522 Teachers responded the questionnaire. Majority of the respondents n=702, 83.6% were from the rural area while n=138, 16.4% from urban area. Overall response rate of females was more than the male staff. 63% of the whole sample was of more than 40 years of age. Majority of respondents were having master degree. The Minnesota Satisfaction Questionnaire (MSQ) was used to collect data from the respondents. Stratified random sampling technique was used to take the sample from population. After seeking permission for survey from Executive District Officer (Education) Sahiwal and Rawalpindi; the researcher send questionnaire through mail to the respondents. Descriptive and inferential statistics was used to analyze the data. Frequencies and percentages along with mean value of responses were tabulated and calculated. The t-test was applied to know the difference of means and Pearson r value was also calculated. The findings of study show that as whole respondents were satisfied with their job. However they were not satisfied with three dimensions (out of twenty) of the job i.e., „advancement‟, „Education Policies‟ and „compensation‟. No significant differences between job satisfaction of academic and administrative staff was found as a whole. However, by parts a significant difference of job satisfaction was found between academic and administrative staff from District Sahiwal. Similarly a significant difference of job satisfaction observed between male and female teachers from District Sahiwal.
