It highlights women's historical leadership roles, especially in the early stages of civilization, with economic activities in their hands. The author critiques classical exegesis for perpetuating a patriarchal and misogynistic system and seeks to reinterpret Quranic teachings to establish gender equality in leadership. The text argues that men and women are equal in their capabilities and contributions, with women performing unique roles, such as childbearing and nurturing, that men do not share. The paper cites Quranic verses, Ahsanul Hadith, Ijma, and Qiyas, to support the claim that women can lead in various sectors independently, including society, education, family, economy, Culture, and religion. It applauds contemporary Muslim societies where women's leadership is acknowledged. The author strongly criticizes groups like the Taliban, considering them divergent from Quranic teachings. The paper concludes by advocating for women's leadership as a lawful and necessary demand, expressing hope that women can lead globally for future peace-a prospect aligned with Quranic ideals. The research aims to rediscover and promote women's leadership in Islam, emphasizing its compatibility with Quranic principles and challenging patriarchal interpretations.

Equalization and Empowerment Culture of Woman in the Quran

Human beings are the most truthful of all things on the earth. Nothing is above them. Among people, women are the most compassionate. Half of the world's population are women. Women are not simply beings who give birth to men, women, and those of a third gender. All men, women, and those of a third gender are one community. The entirety of human society trusts in various religions, folk religions, cultures, thoughts, and philosophies. All faiths have considered women as disregarded, obnoxious, incompetent, and sinful doers. They have been confined to women within four walls and have dominated them for a very long time. Only the divine and religious book, the Qur'an, has given women equality, empowerment, and dignity. Women have a long, strong, and proud history in human civilization. They are the chief mothers of world civilization. From the ground to the sky, women have worked as the founders of every society. Today, the world's superpowers do not desire full and equal women empowerment. They talk about women's leadership at the round table but do not expect it in practice. Only the Qur'an desires to equalize and empower women from the beginning of human creation and livelihood on earth. This paper indicates the theological aspect and may be discussed as an academic study. No other religions or divine books foresee that women would lead all sectors of the world as men do. This paper attempts to prove that the Qur'an has fostered a culture of equalization and empowerment of women in all sectors of the earth.

Improved performance of GaInNAs solar cell after UV-activated hydrogenation

This is due primarily to serious material limitations that arise from the non-ideal growth conditions that are necessary to incorporate nitrogen while preventing phase segregation. There has been some success, most notably Solar Junction's world record power conversion efficiency of a solar cell with a GaInNAsSb cell [2]. Yet, there remains pertinent questions concerning lifetime, reproducibility, and yield in order for this material to become widely used as part of a commercial solar cell. Previously, we reported on the improved photoluminescence of GaInNAs materials which had been achieved through the selective passivation of defect centers. Now, we present results that show that GaInNAs solar cells can be improved using this UV-activated hydrogenation process. Hydrogenated solar cells show a greater than two times improvement with respect to reference cells in terms of short circuit current and external quantum efficiency.

Load settlement curve method for shallow foundations on sand A bstract Briaud and Jeanjean proposed the load settlement curve method for shallow foundations in 1994. This method was limited to square shallow foundations, subjected to vertical monotonie loads applied at the center of the foundation resting on a flat sand surface. This article gives an evaluation of the precision of this method and an extension of the method to rectangular shallow foundations, embedded shallow foundations, shallow foundations near a slope, shallow foundations subjected to an eccentric load and to an inclined load. The precision is evaluated by comparing predicted and measured behavior for 18 foundation load tests. The finite element method and the Duncan-Chang (1970) hyperbolic model are used to obtain the correction factors for scale effect, shape effect, embedment effect, eccentricity effect, inclination effect, and the influence of a nearby slope.

But transmission of such images is vulnerable to serious threats and attacks. To protect the sensitive images from intrusion, certain security measures need to be adopted. LSB based encoding method has been proposed in this paper that utilizes DCT and pixel flipping techniques to form the stego-image. Stego-key generation method is also implemented to validate the authorized receiver during retrieval. The image of the skin disease is considered to be both cover image and stego-image. The receiver can retrieve the original image using key-based decryption algorithm, LSB, and pixel flipping method. The extensive experimental analysis is conducted to demonstrate the efficacy of the proposed method with existing ones.

Cobs with straw colour were harvested in Feb-March 2003 and after harvest maize cobs were sun dried for 2-3 days, then threshed mechanically by hand thresher (supported by RARS). Result and discussion: The average production rate was 2.4 tonnes per acre in all three situations. This was a low yield in comparison to standard production rates of other regions in Bangladesh. However, considering the low investment in sub-fertile soil the cost-benefit was reasonable. Maize cultivation appeared viable and valued. Source of quality seed, access to market and credit support were found to be very important issues. Mono-cropped maize was less susceptible to disease and less labour intensive in comparison with intercrop situation of maize and chilli. From farmers' opinions, maize dyke crop situation was better than intercrop situation in terms of yield. Therefore, mono-crop and dike-crop were found to be widely adopted by char land farmers. From farmers' experience, maize cultivation seemed to be profitable compared to other cereal crops like boro rice (gross income Tk3000-4000 per acre), wheat (gross income Tk2500-3000/acre) and millet (gross income Tk1500-2000/acre).

The current problem on environmental health in relation to water pollution insists for the safe disposal of sewage water. In general, sewage water comprises of heterogeneous organic based chemicals as well as pathogens. EB (electron beam) treatment of the wastewater was found to be very effective in reducing the pathogens as well as organic load. EB dose of 1.5 kGy was sufficient for complete elimination of total coli forms. The experimental results elucidated that the reduction of biological oxygen demand (BOD) (30.38 and 51.7%) in both inlet and outlet sewage samples. Similarly, reduction of chemical oxygen demand (COD) was observed (37.54 and 52.32%) both sewage samples with respect to increasing of irradiation doses (0.45 to 6 kGy). The present study demonstrated the potential of ionizing radiation for disinfection of sewage and to increase the water quality of the wastewater by decreasing BOD and COD. So,...

The effects of the hydrogenation on the minority carrier lifetime were studied using photoluminescence and optical modulation response. An increase of the minority carrier lifetime from 1.8 μs to 3.3 μs with hydrogenation using both methods was observed; however, the processing time shortened from 24 h to 90 min when using the DC bias enhancement. The largest increase in carrier lifetime corresponded to a deuterium density of 9 × 1014 atoms/cm2, as measured by nuclear reaction analysis.

The syndrome is characteristic of enteropathy, and is often fatal within the first 2 years of life. However, the pathogenesis of enteropathy in the syndrome is unknown. Aims: We present a case of MIRAGE syndrome (gestational age 35 weeks, birth weight 1330g) who developed restriction of growth, adrenal hypoplasia, genital anomaly, and enteropathy at the time of birth. Sigmoidoscopy showed longitudinal ulcers in rectum. Aim of this study is (1) to identify whether SAMD9 mutation is involved in early onset inflammatory bowel disease (IBD), and (2) to investigate the involvement of SAMD9 mutation in colitis. Methods: (1) Whole exome sequence (WES) results performed for IBD patients and their families in The Hospital for Sick Children were reviewed. Mucosal expression of SAMD9 in patients' biopsy samples were investigated by immunohistochemistry. (2) We assessed difference in TNF-alpha responsiveness between wild type (WT) or mutated (R1293W) SAMD9 using stably expressing HEK293 cell lines. Difference in apoptosis were measured using western blotting and Caspase assays. Results: (1) Among our WES data, 3 patients from 2 families (2 ulcerative colitis, 1 colonic Crohn's disease) had mutation in SAMD9 gene. Biopsy samples from IBD patients showed increased SAMD9 signals by immunohistochemistry, whereas those from MIRAGE syndrome patient and these 3 patients showed decreased signals. (2) R1293W expressing cells showed increased expression of cleaved Poly ADP-ribose polymerase (PARP) when compared with WT and control. X-Linked inhibitor of apoptosis (XIAP), a known apoptosis inhibitor involves in early onset IBD, were decreased in R1293W mutations. Caspase assay showed increased caspase 3/7 activity in mutated cell lines. Apoptosis was also observed in pathology of the patient's intestinal mucosal biopsy specimen. Conclusions: SAMD9 might be a novel gene associated with development of pediatric IBD. Suppression of XIAP might result in increased apoptosis and intestinal inflammation observed in patients with SAMD9 mutation.

Aim of this study is (1) to identify whether SAMD9 mutation is involved in early onset inflammatory bowel disease (IBD), and (2) to investigate the involvement of SAMD9 mutation in colitis. Methods: (1) Whole exome sequence (WES) results performed for IBD patients and their families in The Hospital for Sick Children were reviewed. Mucosal expression of SAMD9 in patients' biopsy samples were investigated by immunohistochemistry. (2) We assessed difference in TNF-alpha responsiveness between wild type (WT) or mutated (R1293W) SAMD9 using stably expressing HEK293 cell lines. Difference in apoptosis were measured using western blotting and Caspase assays. Results: (1) Among our WES data, 3 patients from 2 families (2 ulcerative colitis, 1 colonic Crohn's disease) had mutation in SAMD9 gene. Biopsy samples from IBD patients showed increased SAMD9 signals by immunohistochemistry, whereas those from MIRAGE syndrome patient and these 3 patients showed decreased signals. (2) R1293W expressing cells showed increased expression of cleaved Poly ADP-ribose polymerase (PARP) when compared with WT and control. X-Linked inhibitor of apoptosis (XIAP), a known apoptosis inhibitor involves in early onset IBD, were decreased in R1293W mutations. Caspase assay showed increased caspase 3/7 activity in mutated cell lines. Apoptosis was also observed in pathology of the patient's intestinal mucosal biopsy specimen. Conclusions: SAMD9 might be a novel gene associated with development of pediatric IBD. Suppression of XIAP might result in increased apoptosis and intestinal inflammation observed in patients with SAMD9 mutation.
