Humor was a weapon of his style and taste. Although in his early life, he was much worried due to the death of his father and wife, but through all his life he enjoyed the people especially his colleagues by military humor. Mostly he wrote in “Hilal”. So, he took military subjects in his humor poetry. In other words, military traditions were the main subject of his poetry. His best-known work is “Barik Nama”. He has also a separate place in the field of character humor (annoying act). He tried to present each and every character of Army in a humorous way. And also described the characteristic of each. If, it is said the king of “annoying act” to Afzal Tahseen, there will be no objection
The role of solar energy and eco‐innovation in reducing environmental degradation in China: Evidence from QARDL approach
No full textIn the past decade, researchers have shifted their interests to explore different ways to mitigate environmental degradation. In that context, the present study explores the role of solar energy and eco-innovation in reducing environmental degradation in China. The study utilized data for the period 1990–2018 and applied the latest available econometric technique, a quantile autoregressive distributed lag model, to determine the impacts of solar energy and eco-innovation on improving China's environmental quality. According to the empirical results, in the long term, solar energy is negatively and significantly associated with CO2 emissions at higher quantiles. Eco-innovation has proven to be the most important channel to mitigate CO2 emissions in China. Eco-innovation is exerting a negative and significant influence on CO2 emissions at all quantiles in the long term. In addition, the population size is causing CO2 emissions to surge significantly at lower quantiles. The empirical analysis reveals that per capita income (PI) is positively associated with CO2 emissions at all quantiles, but it is significant only at higher quantiles in China. We found evidence of unidirectional causality for eco-innovation to CO2 emissions and solar energy to CO2 emissions. However, for population and CO2 emissions, per capita income, and CO2 emissions, we found bidirectional causality. As indicated by our empirical results, solar energy and eco-innovation are the two most effective channels to control CO2 emissions in China. Therefore, policies based on the promotion of eco-innovation and the initiation of new solar energy projects can control emissions and improve environmental quality in China

Thermally tunable phonon–plasmon polariton modes at hexagonal boron nitride (hBN) and indium antimonide (InSb) interfaces
Get PDFThis work examines the propagation of thermally tunable phonon-plasmon modes at the interfaces of hexagonal boron nitride (hBN) and isotropic indium antimonide (InSb). Both theoretical modeling and numerical simulations are carried out to analyze the effect of temperature on surface wave behavior. hBN is realized as a polar material via the Lorentzian model, while InSb is modeled as a temperature-sensitive material (TSM) in the framework of Drude’s model. The possible plasmon-phonon polaritonic interactions are studied for the TSM-elliptic type interface and TSM-hyperbolic type interface. It is reported that by varying the temperature, the surface modes can be tuned for the lower and upper Reststrahlen (RS) bands of hBN. The dispersion curve, effective mode index, propagation length, and phase speed are computed for each case under different temperatures. It is concluded that the hBN-InSb-based phonon-plasmon polariton modes are actively tuned by changing the external temperature in the lower and upper RS bands. Surface waves propagating across the interface can be modulated from the terahertz (THz) region to the infrared (IR) region by changing the temperature of InSb. This study will help researchers to design innovative thermo-optical sensors, plasmonic platforms, detectors, and surface waveguides in the THz and IR regions

’’دی میسج آف قرآن‘‘ از محمداسد؛ کا منہج و اسلوب کا ایک جائزہ: The Review of the Method and Style of "The Message of Quran" by Muhammad Asad
No full textThe Holy Quran is the Book of Guidance and code of conduct for all mankind till the occurance of the Qiyama. The language of the Quran is Arabic, and the quality of this Arabic is quite different from Arabic that is used in daily life of Arabs. As the understanding of the Holy Quran is difficult for Arabs so it is also difficult for non-Arabs and all the people of world. So the translation of the Quran is dire need of time and Ummah that’s why the all the scholars of Muslim Ummah established their scholarships to allow its translation in the world’s languages. Likewise the Holy Quran has been translatated in the English language, George Sale translated it in English firstly. Muhammad Asad was renowed converted Muslim and Pakistani, he contributed in the Islamic Literature and wrote many though proving books on Islamic thoughts. His one main contribution is “The Message of the Quran” English translation. This research deals to analyze the style and methods of his English translation of the Quran.

Indoleamine 2,3-dioxygenase (IDO) is an immunosuppressive enzyme that is linked with progression of cancer. IDO is overexpressed in triple-negative breast cancer (TNBC) cases. Materials and methods: We conducted the first study to analyze IDO expression and overall survival in breast cancer cases in Pakistan. Expression of IDO, estrogen receptor (ER), progesterone receptor (PR), and human EGF receptor 2 (HER2) was evaluated by immunohistochemistry. Formalin-fixed paraffin-embedded breast cancer tissues of 100 (TNBC, n=49 and non-TNBC, n=51) patients were obtained from Shaukat Khanum Memorial Cancer Hospital and Research Centre. IDO expression was analyzed in association with clinicopathological features and overall survival. A total of 100 patients were classified based on the ordinal IDO score variables as low, medium, and high. In addition, overall mean age and SD of patients was 48.28±11.82. Results: Immunohistochemical analysis showed that high IDO was observed in the TNBC patients (65.3%) compared to that in the non-TNBC patients (33.3%). Multivariable analyses showed that TNBC was an independent risk factor for high IDO expression. Overall survival was also significantly associated with IDO score. Conclusion: Our study showed that IDO protein expression is higher in TNBC patients (P<0.01) and may suggest its role in disease pathogenesis. TNBC might be effectively treated with IDO inhibitors. Furthermore, high IDO expression is considerably associated with overall decreased patient survival. IDO might be utilized as a potential biomarker and immunotherapeutic target in breast cancer patients. Keywords: indoleamine 2, 3-dioxygenase, breast cancer, triple-negative breast cancer, Pakista
Primary Diffuse Large B-Cell Lymphoma of Breast: A Rare Form of Gestational Breast Cancer
Get PDFPrimary diffuse large B cell lymphoma of the breast is an uncommon form of gestational breast cancer and its presentation during pregnancy is challenging.
In our case report, a patient presented with a right breast lump during the first trimester of her pregnancy. Biopsy was taken from right breast mass, which was diffuse large b cell lymphoma (DLBCL) double expressive type. She underwent termination of pregnancy and received 6 cycles of multiagent intense chemotherapy along with central nervous system prophylaxis followed by consolidation involved site radiotherapy (ISRT) to breast and axilla after achieving a complete response.
Studies suggest no improvement in the outcome of gestational breast cancer with the termination of pregnancy. However, the presentation of primary DLBCL during pregnancy is extremely rare and the decision regarding pregnancy termination is weighted upon a case by case basis. The paucity of data makes our case report a valuable source for the management of DLBCL breast in pregnancy
Social capital as a determinant of population health outcomes: A global perspective
Get PDFThis study contributes to the health literature by decomposing health outcomes into three dimensions that are physical health, mental health and well-being of individuals. Where physical health is measured using life expectancy, infant mortality and self-rated health indicators while mental health is measured using stress index and addition of smoking in both males and females. Finally, well-being is measured using the index of happiness. The empirical analysis is conducted using OLS and GMM for 61 countries from 1980 to 2014. Overall results indicate that social capital is positively associated with all dimensions of health outcomes as high trusting individuals report better health outcomes in comparison to low trusting individuals. The results also reveal that the impact of social capital on mental health is stronger than the impact on physical health. Moreover, social capital is more conducive for controlling stress index than producing happiness. The main message of this research is that social capital has the power to influence diverse dimensions of population health. Therefore, the public policies need to focus on social indicators to overcome health disease burden
Analysis and Design of Reflectarray Antennas for Bandwidth Enhancement, Feed Matching, and Portability
Get PDFReflectarray (RA) antennas are introduced as an alternative to the conventional parabolic reflectors and antenna arrays. The RA provides the advantages of both reflectors and arrays. The narrow bandwidth is one of the distinct disadvantages of RA. The RA bandwidth is primarily limited by two factors, the element bandwidth, and the spatial phase delay. As the RA size is fixed with a proper focal distance, the second factor is hard to be used in the RA bandwidth optimization. It is impossible to design a broadband RA using narrowband elements, so wideband elements are developed in a unit cell of a periodic structure to further provide wider overall antenna bandwidth. In the literature review, 10-15 % RA bandwidth has been observed, which is mainly because of the used narrowband elements.
Several RA antennas operating in the Ka-Band are designed and fabricated to learn an understanding of the RA with wideband characteristics. New wideband elements for linear polarization (LP) and circular polarization (CP) are utilized. A bandwidth of 22 % in LP-RA antennas is achieved using the proposed wideband elements. Over 50 % gain, and 50 % axial ratio bandwidth, and 57-62 % maximum aperture efficiency are experimentally measured for the CP. The effect of the edge diffraction on the phase correction is also investigated. The initial study showed little effect, but the considered RA size is small to highlight this effect. The matching of the feed is deteriorated when placed in front of the reflector. Therefore, few methods are implemented to improve the antenna reflection coefficients. The experimental results show possible improvements.
The proposed work is categorized into three Parts. Part A provides a comprehensive study of the wideband element designs for both LP- and CP-RA. Part B utilizes the wideband elements developed in Part A, in the RA environment and introduces the performance of the antenna. In part C, textile-reflectarray (TRA) is proposed using conductive thread and shielded fabric, which is the first to be considered as a new trend in the field of RA. The element analysis and measurements show promising results. However, when implemented in the RA, the shielded fabric does not perform as expected. This problem is resolved by introducing a dual-sided embroidered reflectarray antenna where a flexible frequency selective surface (FSS) embroidered at the textile material using a conductive thread is used at the back side of the radiating elements replacing the ground plane. The measured results of the first ever built flexible, portable textile-RA show good antenna performance. An FSS based flexible portable and rollable circularly polarized TRA design is also presented using the wideband cross Bowtie elements. The radiating elements are embroidered using conductive thread.
The initial results exhibit good performance of the proposed CP TRA antenna. For RA with small f/D, the spatial delay problem is the main reason for limiting the bandwidth even with wideband RA elements. This issue is solved by introducing a new split aperture into panels that reduce the difference in the path length between the center and those away towards the RA edge. This method shows a significant improvement in the RA bandwidth
