نگاہِ شوق کا قبلہ مدینہ


نگاہِ شوق کا قبلہ مدینہ
الٰہی! ہم کو بھی دکھلا مدینہ

مری چشمِ تصوّر رو پڑی ہے
مری پلکوں پہ آ ٹھہرا مدینہ

سعادت سے ہیں یہ محروم اب تک
نِگاہوں نے نہیں دیکھا مدینہ

کہاں میں عبدِ عاصی اور وہ نگری
’’کہاں میں ہوں کہاں پیارا مدینہ؟‘‘

خدایا! آرزو بَر آئے میری
میں دیکھوں پیارے آقاؐ کا مدینہ

مری راہوں میں قدسی پَر بچھائیں
مری منزل بنے ، مکّہ ، مدینہ

مقامِ حسرت و توفیق یکجا
نجانے کیسے دیکھوں گا مدینہ

The Role Of Attachment Style And Marital Quality In Attachment Injury Couples

The attachment system is thought to facilitate relationship goals by motivation seeking and bonding activities with significant others, particularly under times of stress (Bowlby, 1982). Attachment theory has also contributed to further understanding the marital relationship in terms of profound psychological and physiological interdependence. It is perhaps this interdependence that causes damage to the quality of attachment relationship. Hence, attachment injury is defined as “a specific incident or event in which one partner is unresponsive and inaccessible when one partner cries out for help in extreme need” (Johnson & Makinen, 2001). Therefore, marital distress or breakup in couple’s relationships does not happen suddenly, so understanding of attachment injury in relation to individual’s marital quality and attachment style would help practitioners to be equipped for appropriate and effective inventions. Further it would also help counsellors and mental health professionals to be familiar with the complexities of the topic by dealing with consequences of an attachment injury ethically and competently.  Therefore our study aimed at examining the prevalence and nature of attachment injury and its effect on marital quality, in a group of married heterosexual couples. It also attempted to associate attachment styles with and without attachment injury in couples. The study employed cross-sectional exploratory design with a set of self-administered measures. The sample comprised of 400 married individuals from urban Bangalore. Statistical results showed those individuals who were experiencing attachment injury are associated with poor marital quality. It was also seen that attachment injury was found to be associated with gender and insecure attachment style. Therefore our findings suggest that poor marital quality with insecure attachment style plays an important role in attachment injury over time. Based on the attachment style, further intervention strategies and effective programs should be designed for marital counselling. And marital enrichment programs may be useful to enhance marital quality to prevent the marital distress or breakups.

Laser Cooling and Trapping of Cesium Atoms

In this thesis, the Pakistan‟s first ever magneto optical trap has been designed, developed and studied with cesium atoms in a vapor cell. Keeping the density of background cesium atoms fixed, the trap performance depends upon the magneto-optical operating parameters, i.e. the intensity and detuning of the trap laser and the gradient ⃗⃗ of the quadrupole magnetic field, since these parameters determine the radiative force ( ) acting upon the atoms. In the present work, the trap dynamics of the cesium MOT has been investigated as a function of trap laser intensity and magnetic field gradient ⃗⃗ , keeping the detuning of the trap laser fixed at an optimum value of . Assuming, that all cesium atoms of the background ( ) which enter the trapping region with velocities in the range will be trapped with a certainty of 1, it is possible to develop a model for the capture rate in terms of the capture velocity of cesium vapor cell magneto-optical trap. By experimentally measuring the capture rate as a function of trap laser intensity and magnetic field gradient ⃗⃗ and determining the capture velocity corresponding to the measured capture rate by using simulation graph, it is possible to investigate the intensity and magnetic field dependence of the capture velocity ⃗⃗ . In the present work, the capture dynamics of the magneto-optical trap has been fully investigated. Finally, the magneto-optical trap is suspected to be a stochastic dynamical system as well. Due to the random photon recoils ( ⃗ ) imparted to the atom, the radiative force has a fluctuating force superimposed upon the average force 〈 〉. As a consequence of this fluctuating force, the external and internal dynamics of the atoms become stochastic whose signatures can be found in the resonance fluorescence emitted by the trapped atoms. In the present work, by using the techniques of non-linear time-series analysis, the stochastic dynamics of atom-photon interaction in a magneto-optical trap has been investigated. In short, the conclusion of the thesis is that the magneto-optical trap promises to be an interesting non-linear quantum dynamical system.
