Wireless energy harvesting, a technique to generate direct current (DC) electricity from ambient wireless signals, has recently been featured as a potential solution to reduce the battery size, extend the battery life, or replace batteries altogether for wearable electronics. Unlike other energy harvesting techniques, wireless energy harvesting has a prominent advantage of ceaseless availability of ambient signals, but the common form of technology involves a major challenge of limited output power because of a relatively low ambient energy density. Moreover, the archetypal wireless energy harvesters are made of printed circuit boards (PCBs), which are rigid, bulky, and heavy, and hence they are not eminently suitable for body-worn applications from both aesthetic and comfort points of view. In order to overcome these limitations, textile-based wireless energy harvesting architectures have been proposed in the past decade. Being made of textile materials, this new class of harvesters can be seamlessly integrated into clothing in inherently aesthetic and comfortable forms. In addition, since clothing offers a large surface area, multiple harvesting units can be deployed to enhance the output power. In view of these unique and irreplaceable benefits, this paper reviews key recent progress in textile-based wireless energy harvesting strategies for powering body-worn electronics. Comparisons with other power harvesting technologies, historical development, fundamental principles of operation and techniques for fabricating textile-based wireless power harvesters are first recapitulated, followed by a review on the principal advantages, challenges, and opportunities. It is one of the purposes of this paper to peruse the current state-of-theart and build a scientific knowledge base to aid further advancement of power solutions for wearable electronics.
... Metals having large atomic numbers, atomic weights, and densities are known as heavy metal [37] [55][68] [80]. Some of these metals, such as calcium, magnesium, zinc, and iron, are needed for human health, whereas others, such as cadmium, arsenic, lead, nickel, chromium, copper, and mercury, have been shown to be very hazardous to humans [38][72] [73]. Ingestion, inhalation, and dermal contact are all ways for heavy metals to enter the human body [4][26] [27]. ...
Numerous articles on the examination of heavy metals in human teeth have been published in recent years. In today's toxicology area, heavy metal poisoning is a widespread issue. It has been discovered that long-term exposure to heavy metals typically present in traces, in our everyday meals, drinking water, and in the environment as pollution causes heavy metal poisoning in people. Industrial effluents, coal and oil, as well as a variety of consumer items, such as cosmetics, can all cause this type of exposure. Teeth, which are often thought of as exoskeleton parts, store heavy metals with a high affinity and represent long-term exposure information. Instead, then examining the entire tooth, just chosen sections of dentine are examined. We have combined the work done on the examination of heavy metals in human teeth using several instrumental approaches in the current study.
... Its purpose is to check to what extent the objectives have been achieved. The Examination is a process for testing the ability of achievement of students in any area [7] [8] [9] [10] [11] [12]. In schools, examination tests the students' achievement related to their subjects to promote them from one grade to another. ...
The examination paper is an assessment tool that is used to determine the learning performance and capability of students and rank them among a closed group belonging to the same class. It contains a set of questions developed through various techniques to check skills and knowledge. It is observed that students are found dissatisfied with the current Annual Exam results due to poor governance of Exam conduct and unexpected or erroneous exam papers. Whereas, Teachers, School Heads, and Educational Administrators are not clear about their role, evaluation criterion, qualities of a good Test, exam paper construction process, and characteristics of a test or exam paper constructor. This shows the illogical activities and non-serious attitude of Responsible Authorities. So, this study covers the way to analyze the ongoing practices related to the Annual Examination Paper construction process for secondary schools. A structured interview questionnaire tool was prepared for Responsible Authorities i.e. Teachers, School Heads and Educational Administrators of the District Hyderabad, Sindh Pakistan. The collected data was assessed through a qualitative approach. The study reveals the malpractices in the Annual Examination Paper construction process. The responsible authorities do not have any knowledge of the paper construction process and its implementation. Even the majority of them have not adopted any rationalized approach related to their role such as “Qualities of a Good Test”, “Curriculum-Based Evaluation Criterion”, “Centralized Examination Administration Process”, and “Determining the Characteristics of a Good Paper Constructor”. This study suggests the practical measures for fair and excellent academic achievement reflected by the students’ effort that could be assessed with fair justice.

... . The absorption onset is around 400, which corresponds to a band gap of 3.2 , indicating that nanowire arrays absorb light only in the ultraviolet region. While at longer wavelength, there is no absorption; the curve looks very flat in visible region, indicating that nanowires have good crystal quality.The transmittance reaches to 0 when the wavelength is below 380, indicating the nanowire arrays have high absorption coefficient[46][47][48][49][50]. ...
The Nanostructured materials like nanotubes, nanowires, nanorods, and nanobelts etc. have remained the subject of interest these days because of its unique thermal, mechanical and optical properties. Zinc Oxide (ZnO), is the most attractive material due to its unique properties and availability of a variety of growth methods. At nanostructured level, the properties of ZnO can be altered by controlling the growth process, such as the shape, size, morphology, aspect ratio and density control. In this work, Aligned ZnO Nanowires (NWs) were successfully synthesized by Chemical Vapor Deposition (CVD) on Aluminum doped Zinc Oxide (AZO) substrate. The effects of different growth parameters such as growth temperature, flow rate of oxygen and distance of substrate from source on growth of aligned ZnO NWs have been investigated and discussed in detail. Morphologies and structures of grown nanowire arrays were characterized by Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD). Optical properties were optimized by UV-visible transmittance spectra, and photo luminescence (PL).

This paper presents a study of plasma emission from Lithium Fluoride surface produced by Q-switch Laser (Nd: YAG Laser) having 1064 nm wavelength. The sample has been targeted with Q-switch laser pulses at atmospheric pressure in air. Only neutral Lithium (Li) is confirmed in the emission spectrum of Lithium Fluoride plasma. The Boltzmann distribution technique was used to calculate Electron Temperature(T_e). Similarly, Stark Broadening Profile (SBP) technique was used to calculate the Electron Number Density(N_e). T_e is estimated at variable distances along the propagation of plasma plume from the sample surface. Beside that we studied the changing of N_e as a function of distance along the propagation of plasma plume from the surface of the sample. We have also calculated the Inverse Bremsstrahlung (IB) absorption co-efficient and its variation along the distance. It is observed that the T_e, N_e and IB absorption co-efficient decreases as distance increases. In addition, self-absorption of radiation also decreases as temperature decreases.
