We investigate the light deflection in the weak field approximation from the accelerating charged AdS black hole. For this purpose, we apply the Gauss–Bonnet theorem to calculate the light deflection in the weak field area and use the Gibbons–Werner approach to analyze the optical geometry of the accelerating charged AdS black hole in the non-magnetic plasma absence/presence of a non-magnetic medium. We also represent the graphical behavior of the light deflection angle w.r.t. the impact parameter. We also compute the light deflection angle using Keeton and Petters approximations under the impact of accelerating charged AdS black hole geometry. Furthermore, by using the ray-tracing approach, we determine the shadow in the nonmagnetic plasma presence and also demonstrate that graphical shadow has an impact on the gauge potential, non-magnetic plasma frequencies and charge.

全球化是全球出现的一种重大现象。与这种转变相关的变化在存在的方方面面都是深刻而明显的。与前现代全球化时代(特别是第一次世界大战后)相比,科学技术取得了重大进步,经济活动大幅增长,对权力的理解和利用发生了根本性转变,世界各地社会文化框架也发生转变。技术进步促进了全球化,为国家、经济和文化创造了一个激烈的竞争环境。全球化是由各种力量推动的,例如先进的信息和通信技术、大众媒体、跨国组织、跨国公司、政府间组织和非政府组织。这些力量对生活的不同方面都有重大影响,包括国家资源生成、经济稳定或不稳定、政治制度影响、社会转型,甚至维持全球权力平衡。复杂的形势要求政府拥有越来越先进的能力,而高质量的国家在当今时代是必不可少的。全球化进程无疑在全球治理结构的政策和执行方面都存在重大缺陷。然而,这些缺点也可以归因于个别政府的内部脆弱性。本论文研究了全球化对21世纪巴基斯坦国家和社会的政治和社会影响;全球化如何影响巴基斯坦的政治,削弱巴基斯坦在21世纪的主权?全球化如何影响巴基斯坦社会,如何改变21世纪巴基斯坦的文化自我?巴基斯坦在21世纪的政治和社会领域都受到全球化的影响。巴基斯坦是一个发展中国家,拥有重要的战略位置、核能力(原子能)、丰富的自然资源、多样化的文明以及年轻人口的强大能力。然而,其政治制度的不稳定状态、经济薄弱和人口分裂正在造成重大障碍,特别是在全球化带来的困难方面。全球化在国家生活的几个方面带来了深刻的变化,这对一个缺乏足够管理能力的国家和社会提出了相当大的挑战。自威斯特伐利亚时代以来,国家一直是全球政治的主要参与者和卓越机构,拥有高度的主权,基本上不受外部和内部力量的影响。在现代,随着全球化势头的增强,非国家机构的影响越来越大,它们对国界的干预也在增加。与任何其他国家一样,巴基斯坦不能将自己与这些影响隔离开来。为了更好地理解这一现象,我们将研究全球化如何影响全球形势,特别是它如何影响巴基斯坦,以便最终验证这些假设。为此,将采用定性研究方法,并制定一个概念框架,以巴基斯坦为例,确定我们可以评估全球化如何影响发展中国家的界限。文化将作为一个变量,分析巴基斯坦文化和社会的西方化和现代化,以确定全球化对巴基斯坦社会的影响。巴基斯坦目前正面临着全球化对其21世纪政治和社会的切实影响。不利的国内环境,主要特点是治理不善、不利的社会经济指标和政治不稳定,阻碍了巴基斯坦有效参与全球化的能力。在这个进步的时代,国家权力的概念发生了转变。常规军事不再是评估一个国家主权地位强弱的唯一标准。国家实力的基本组成部分通常被视为软实力,包括技术实力和经济实力。巴基斯坦尽管是核大国,但容易受到各种形式的内部和外部力量的影响。在全球化时代,巴基斯坦的主权正在受到破坏,而国内力量的进步因素并没有被纳入国家的整体实力。巴基斯坦积极参与全球化进程的障碍可归因于几个原因,包括其经济和技术依赖性、不稳定的治理体系、识字率低以及公众观点不同的分裂社会。技术和金融领域的相互依存使一个国家变得脆弱并依赖世界其他地区或国际组织,从而阻碍了其保持自治和抵抗外部和内部影响的能力。全球化要求在世界范围内实现建立在科学和技术进步基础上的社会现代化。文明现代化进程对于在全球范围内相互联系的国家和社区至关重要。世界各国社会正在通过两种主要方法应对现代化的挑战:追求植根于科学技术进步的真正现代化,或采用西方化——主要体现在文化领域模仿西方现代性。巴基斯坦社会也不能幸免于21世纪全球化的影响,因为它目前正经历着对发达社会的重大影响。该研究考察了全球化对巴基斯坦的现代化、西方化的影响。由于这种暴露,巴基斯坦社会正在吸收西方社会的影响。模仿现象通常被认为是社会的西化,在经济上处于不利地位的文明中普遍存在。国家的显著进步和社会的进步使老牌国家成为欠发达文化的榜样,他们渴望效仿这些文化。巴基斯坦社会缺乏重大的科学和技术进步,以及模仿主要关注文化方面,这表明真正的现代性并没有在这种情况下发生。模范社会所取得的真正进步,从根本上说是建立在它们在科学和技术领域所取得的成就之上的。本论文分别由五章组成。第一章是“导言”,简要介绍了全球化的整个现象,即全球化是全球性的重大发展。与这种程序相关的变化在生活的方方面面都是深刻而明显的。这一现象表明,技术和科学知识取得了重大进步,经济活动大幅增长,力量概念发生了结构性转变。它还强调了研究的背景、研究问题和研究的意义。目前,全球是相互联系的。由于全球化,世界各地的政治、社会、经济和文化联系正在发生变化。由于壁垒的消除、高度的竞争、跨境经济自由化以及购买者的品味和兴趣日益相同,以及国际资本和劳工迁移的灵活性,这些扩大了经济、社会、政治、商业和数据联系。本部分还包含主要论点、研究方法、文献综述和概念框架。第二章是“从政治和

Computational calculations using density functional theory(DFT) were performed for the first time using the full potential linearized augmented plane wave plus local orbital method(FP-LAPW + LO) to determine the structural, elastic, electronic and magnetic properties of europium-based cubic perovskites EuYO_(3)(Y=Cr, Mn, Fe). The exchange correlation potentials of GGA along with some analytical methods were adopted for the computation of structural and elastic properties. Moreover, the GGA + U formalism was also added for obtaining more precise electronic and magnetic properties, particularly to address the Eu-4f and Y-3d orientations in the spin-polarized double cell symmetry. The observed lattice parameters of these compounds are consistent with experiment. The observed bulk moduli predict that EuCrO_(3) is harder and less compressible than EuMnO_(3) and EuFeO_(3). The calculated tolerance factors of these compounds are within the cubic symmetry range. Our computed critical radius of EuCrO_(3) shows that EuCrO_(3) has a larger migration energy. Based on their elastic properties, these compounds are ductile in nature. We also computed the thermal properties of these compounds. The band structures and density of states show that these compounds are metallic in character. The lowest ground state energy and magnetic moments of these compounds expose their ferromagnetic nature. The metallic nature and strong ferromagnetism of these compounds make them promising applicants for application in spintronic.
