سائنس آئی بہاریں لائی

سائنس آئی بہار یں لائی
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز اسا تذہ کرام اور میرے ہم مکتب ساتھیو! آج مجھے جس موضوع پر لب کشائی کا موقع فراہم کیا گیا ہے وہ ہے:’’سائنس آئی بہاریں لائی ‘‘
صدرِذی وقار!
اللہ تعالیٰ نے انسان کو اشرف المخلوقات بنایا عظمت کا تاج اس کے سر پر سجایا اور جملہ مخلوقات میں اسے اعلیٰ وارفع مقام پر فائز فرمایا۔ اس کی عظمت کا سبب علم کے ساتھ ساتھ عقل کو بھی قرار دیا اور غیر ذوی العقول مخلوقات میں سے اس ذوی العقول مخلوقات کی اہمیت کا لوہانوری اور غیر مرئی مخلوق ملائیکہ سے بھی منوایا یہاں تک کہ وہ اس حیوانِ ناطق کے سامنے سجدہ ریز ہوئے۔
صاحبِ صدر!
یہ ساری عظمتیں ، یہ ساری رفعتیں، یہ ساری شفقتیں، یہ ساری عنایتیں ، یہ ساری سعادتیں ، یہ ساری فضیلتیں اللہ تعالیٰ نے انسان کو عطا فرمائیں کیونکہ علمِ الٰہی میں موجودتھا کہ میری کائنات کے گلشن میں بہار انسان لائے گا۔ میری زمین پر فلک بوس پہاڑوں سے جوئے شیر انسان نکالے گا، آسمان پر پرواز یہ انسان کرے گا۔ خونخوار درندوں کو مطیع میرا یہ انسان کرے گا۔ انسان کی عظمت و رفعت کی بلندیوں پر فائز کرنے والی اللہ تعالیٰ کی ذات ہے اُس نے دنیاو مافیہا کی ہر چیز انسان کے لیے پیدا فرمائی اور انسان کو اپنی عبادت کے لیے پیدافرمایا۔
جانور پیدا کیے تیری وفا کے واسطے
چاند سورج اور ستارے ہیں ضیاء کے واسطے
کھیتیاں سر سبز ہیں تیری غذا کے واسطے
سب جہاں تیرے لیے اور تو خدا کے واسطے
معزز سامعین!
سائنس علم کا ایک شعبہ ہے، سائنس کا لفظ جب قوت ِسماعت پر دستک دیتا ہے۔ سائنس کا لفظ جب قوت بصارت کو متحرک کرتا...

Relationship of Work Engagement and Quality of Work Life with Nurses Performance in Installations of General Regional Hospital Makassar

Performance is the work result in quality and quantity achieved by employees in carrying out their duties in accordance with the responsibilities assigned to them. The role of reliable and professional employees is very helpful in improving organizational performance. This study aims to analyze the relationship between Work Engagement and Quality of Work Life with the Performance of Nurses in Inpatient Services in Makassar City Hospital. This type of research is a quantitative study using an observational study with a cross-sectional study design. Sampling using stratified random sampling so that the sample in this study were nurses in the inpatient installation of Makassar City Hospital, totaling 167 respondents. The results showed that there is a relationship between Work Engagement based on the Vigor dimension, the Dedication dimension, the absorption dimension, and the nurse's performance. There is a relationship between Quality of Work Life and the performance of nurses in Makassar City Hospital. It is recommended that hospital management keep paying attention to work engagement, especially the Vigor dimension in order to increase the morale of nurses. Leaders need to know what their employees need so that employees can work according to organizational expectations, one of which is by providing motivation. Implementing a culture of health in the work environment so as to create a safe working atmosphere, developing career path plans for nurses, and internalizing the values of good work culture to maintain a sense of pride in the institution.

Parallel and Perpendicular Propagating Modes and Instabilities in Degenerate and Non-Degenerate Plasmas

In this thesis we focused on the linear analysis of waves and instabilities propagating along and across the ambient magnetic field in the degenerate and non- degenerate plasmas. In the first part of thesis employing Vlasov-Maxwell set of equations; we have investigated the O-mode and whistler mode instability in a degenerate anisotropic magneto plasma environment and compared the results to those reported for classical plasmas. We propose the excitation of a new banded type of instability for the O-mode case, which grows at some particular values of temperature anisotropy and external magnetic field. For the case of whistler wave, we observe instability saturation mechanism similar to the case of classical plasmas. The existence of both O-mode and whistler mode instability has been observed only for some specific range of unstable wave numbers. The possible excitation of such instabilities in solid state plasma has been discussed, particularly for semiconductor and semimetal plasmas. In the second part general dispersion relation for the right hand circularly polarized waves has been derived using non-relativistic spin quantum kinetic theory. Employing the derived dispersion relation, temporal and spatial damping of the right hand circularly polarized waves is studied for both the degenerate and non-degenerate plasma regimes for two different frequency domains: (i) ??||??>>(??+????),(??+??????) and (ii) ??||??≪(??+????),(??+??????). Comparison of the cold and hot plasma regimes shows that the right hand circularly polarized wave with spin-effects exists for larger k-values as compared to the spinless case, before it damps completely. It is also found that the spin-effects can significantly influence the phase and group velocities of the whistler waves in both the degenerate and non-degenerate regimes. The results obtained are also analyzed graphically for some laboratory parameters to demonstrate the physical significance of the present work. In third part the dispersion relations for the weakly magnetized perpendicular propagating modes (O-mode, X-mode, and upper hybrid mode) based on the ultra-relativistic Fermi-Dirac distribution function with chemical potential are derived using the Vlasov–Maxwell model. The results are presented in terms of Polylog functions without making any approximation. It is found that as the ratio ????⁄ is increased, the cutoff points shift downward. A comparison is also performed with the previously derived results for ultra-relativistic Maxwellian distribution. The forth part contains the discussion on the whistler instability in non-degenerate semi-relativistic bi- Maxwellian plasma. The dispersion relations are analyzed analytically along with the graphical representation and the estimates of the growth rate and instability threshold condition are also presented in the limiting cases i.e.ξ±=(??±????)/ ???||???≪1 (resonant case) and ξ± >>1 (non-resonant case). Further for field free case i.e., B0=0, the growth rates for Weibel instability in a semi-relativistic bi-Maxwellian plasma a represented for both the limiting cases.
