74. Al-Muddaththir/The Enrobed

74. Al-Muddaththir/The Enrobed

I/We begin by the Blessed Name of Allah

The Immensely Merciful to all, The Infinitely Compassionate to everyone.

74:01
a. O Al-Muddaththir!
b. O The Enrobed - Muhammad!

74:02
a. Arise and invite people to profess Allah’s Unity and Uniqueness,
b. and warn against disobedience!

74:03
a. Proclaim the Greatness of your Rabb - The Lord,

74:04
a. and purify your garments,

74:05
a. and keep away from all paganism.

74:06
a. And do not extend a favor in expectation of return of a favor.

74:07
a. And be steadfast for the Cause of your Rabb - The Lord.

74:08
a. Finally, when the Trumpet – call of the Resurrection - will be sounded,

74:09
a. that vey time will, indeed, be a very Distressful Time,

74:10
a. it will not be easy for the disbelievers;
b. but it will be easy for the believers despite the intensity of its harshness and horrors.

74:11
a. So leave it to ME to decide what to do with the one whom I created alone,

74:12
a. and then I granted him ample means - abundant and continuous,

74:13
a. and sons to be by his side as a means of power,

74:14
a. and made everything in life comfortable for him,

74:15
a. still he would be greedy, wanting that I should give him more -
b. while mocking and ridiculing MY Messenger Muhammad.

74:16
a. By no means!
b. I shall...

IS REGULATORY EMOTION SELF-EFFICACY PLAYING A MEDIATING ROLE? IMPACT OF LIFESTYLE HABITS ON SUBJECTIVE WELL-BEING

Background and Aim: The objective of the research is to investigate the impact of lifestyle habits on subjective wellbeing in the presence of role of regulatory emotion self-efficacy as a mediator. Vital for wellbeing, longevity, productivity, relationships, and general quality of life in all areas is a healthy lifestyle. Methodology: A cross-sectional study has been conducted for 271 Students had been selected as respondents. Smart Pls has been used for calculating the reliability, validity of questionnaire and as well as hypothesis testing. Results: Food disorder, healthcare anxiety, regulatory emotional self-efficacy have direct and indirect significant impact on subjective well-being. But sleeping disorder has showed the direct and indirect insignificant impact on subjective well-being. Limitation and Future Implications: Because of time constraints, a lack of comprehension of the research, and a healthy lifestyle people are not aware of health benefits, they had less knowledge about it and were hesitant about a discussion. Originality: The role of regulatory emotion self-efficacy has not been used as a mediator during the relationship of lifestyle habits and subjective well-being. Conclusion: Subjective well-being is defined as gratification and satisfaction with one’s life. Regular physical activity is important in order to enhance the self-efficacy and emotional well-being. Good nutrients and a balanced diet provide a person with enough energy to carry out the tasks of daily life effectively.

Analytical and Optimization Based Modeling Techniques to Assess the Performance of Submicron Sic Mesfets

In therst part of the thesis, a detailed analytical mathematical model describing I ? V characteristic of a submicron SiC MESFET has been presented. Poisson''s equation with appropriate boundary conditions is solved to determine potential distribution inside the channel. The location of Schottky barrier gate with corresponding depletion layer width where the carrier''s velocity gets saturated is evaluated. It has been demonstrated that the depletion modi cation underneath the Schottky barrier gate causesnite output conductance in the saturation region of operation. I ? V characteristics of submicron SiC MESFET have been modeled and compared with conventional velocity saturation techniques, where the depletion layer after the onset of current saturation has been treated as constant. It is noted that the proposed depletion layer modi cation technique, when incorporated in the device modeling, gave15.9% improvement in the modeled out characteristics of a submicron SiC MESFET. In the second part, an improved empirical model has been presented to simulate DC and pulsed I ? V characteristics of SiC MESFETs. A comparative analysis has been carried out by employing swarm optimization technique and it has been established that the proposed model, dependent upon the device characteristics, is7-24% better than its counterparts. Based on simulated characteristics, numerous parameters de ning the device geometrical structure have been estimated to a good degree of accuracy. It has been shown that the developed technique is versatile enough and can be a useful tool for device simulation softwares. In the third part, a technique has been developed to estimate intrinsic small signal parameters of submicron SiC MESFETs, designed for high power microwave applications. In the developed technique, small signal parameters are extracted by involving drain-to-source current, Ids instead of Schottky barrier depletion layer expression. It has been demonstrated that in SiC MESFETs, the depletion layer gets modi ed due to intense transverse electriceld and/or self-heating e ects, which are conventionally not taken into account. Thus, assessment of AC small signal parameters by employing depletion layer expression loses its accuracy for x devices meant for high power applications. A set of expressions for AC small signal elements have been developed using Ids and their dependence on device biasing have been discussed. The validity of the proposed technique has been demonstrated using experimental data.
