implementation of wireless technologies based on the vehicular ad hoc sensor network （VASNET） may provide support for the search and rescue （SAR） team to operate effectively in natural disaster events, such as landslide, earthquake, flooding, and tsunami. The operations of SAR team are very challenging in such events due to the possible damages of the existing telecommunication infrastructures. The existing deployment of the cellular communications infrastructure may be partially or completely destroyed after the occurrence of these natural disasters. Thus, the current VASNET infrastructure must be able to support the infrastructure-less network by integrating other green wireless technologies that can benefit the SAR team, which can indirectly save more human lives and reduce the number of casualties. Therefore, the integration of green Internet of things （loT） and VASNET is proposed to form a heterogeneous framework for data dissemination in SAR operations. In addition, this paper also discusses the existing lot framework in disaster scenarios with future research direction for IoT using on any aspect, especially related to the natural disaster scenarios.

This article addresses melting heat transfer in magnetohydrodynamics(MHD)nanofluid flows by a rotating disk. The analysis is performed in Cu-water and Ag-water nanofluids. Thermal radiation, viscous dissipation, and chemical reactions impacts are added in the nanofluid model. Appropriate transformations lead to the nondimensionalized boundary layer equations. Series solutions for the resulting equations are *** role of pertinent parameters on the velocity, temperature, and concentration is analyzed in the outputs. It is revealed that the larger melting parameter enhances the velocity profile while the temperature profile decreases. The surface drag force and heat transfer rate are computed under the influence of pertinent parameters. Furthermore, the homogeneous reaction parameter serves to decrease the surface concentration.

The direct band gap ZnTe with transition metal （TM） impurities plays a vital role in optoelectronic and spintronic applications. In the present study, we use the advanced modified Becke-Johnson （mBJ） functional for performing the structural computations and detailed investigations of the optical characters in Zn1_xTMxTe （TM = Fe, Co） alloys with 0 ≤ x ≤1. By employing the FP-LAPW method, we determine various optical parameters for the ternary alloys and for the end binaries. The calculated static dielectric constants and optical band gaps for Zn1_xTMxTe （TM = Fe, Co） have an inverse relation that verifies the Penn model. We find that the static dielectric constant is nearly equal to the square of the static refractive index, and both increase with TM content. Furthermore, we also find a slight shift of peaks to a higher energy region with increasing TM concentration. The decreasing band gap and high value of the absorption in the visible region of electromagnetic spectrum make these alloys suitable for photonic and solar cell applications.

在这篇研究论文中,我们努力研究媒体在风险传播中的作用,特别是在大流行初期在巴基斯坦和中国的COVID-19框架中。该研究旨在了解巴基斯坦和中国顶级英文报纸对冠状病毒大流行的新闻报道方式。本文根据框架理论分析了巴中印刷媒体中COVID-19的框架和主题。本研究论文强调了COVID-19期间使用的最显着的框架,这也有助于我们理解媒体报道的异同以及媒体在风险沟通中的作用。毫无疑问,媒体框架为各国政府应采取的政策反应、决定和实际步骤提供了有益的指导。在这方面,媒体框架突出问题,提供道德判断,诊断原因,并建议补救措施。此外,它们还可以为地方和国家一级的政策和决策者提供有用的见解。在分析了2020年1月至2021年2月在《中国日报》和《黎明》等报纸上与COVID-19相关的新闻报道后,我们收集了11个主题,这些主题在我们的研究所涉及的COVID-19早期阶段几乎是一致的。然而,在中国和巴基斯坦,这些帧在新闻报道和新闻报道中的发生率和性质是完全不同的。在研究期间,我们发现《中国日报》和《黎明报》在COVID-19初期的新闻报道和媒体报道中,通过使用框架,在风险沟通中起着重要的作用。在这两份报纸上,我们发现这两份报纸都是与COVID-19相关的及时和可信信息的来源,这使得主流媒体成为有效风险沟通过程中的重要利益相关者。我们发现,这两份报纸都通过使用多种不同的框架提供了有用的见解。关于COVID-19的新闻报道和新闻报道的研究是非常重要的,因为它们在卫生紧急情况的建设中起着关键作用。像COVID-19这样的健康危机的框架为主流媒体、公共当局和普通民众传递了许多教训。分析突发卫生事件的新闻报道及其与COVID-19特别相关的框架,对于应对未来的流行病和传染病爆发具有至关重要的意义。
