Abstrak            Penyebaran virus berbahaya bernama Covid-19 yang tengah terjadi saat ini telah menciptakan berbagai polemik dan persoalan di tengah kehidupan masyarakat baik persoalan ekonomi, sosial, politik maupun agama khususnya. Misalnya saja, polemik mengenai penangguhan atau larangan mengenai ibadah shalat juma’at ataupun berjamaah di masjid yang mana persoalan tersebut melahirkan berbagai reaksi pro-kontra dari kalangan masyarakat. Masyarakat yang pro menganggap bahwa hal tersebut sebagai bentuk pencegahan dan antisipasi penyebaran virus korona atau Covid-19 yang tengah mewabah. Adapun masyarakat yang kontra terhadap penangguhan tersebut memandang bahwa hifdz al-din (memelihara agama seperti ibadah shalat) lebih utama dari hifdz al-nafs (memelihara jiwa atau nyawa). Oleh sebab itu, tujuan utama penelitian ini ialah untuk menjelaskan tinjauan Maqasid al-Shariah terhadap pembatasan, penangguhan, serta larangan pelaksanaan ibadah shalat Jum’at maupun lainnya semasa terjadi sebuah wabah. Metode yang digunakan penulis dalam penelitian ini ialah dengan menggunakan metode kualitatif penuh serta data dokumentasi yang terkait dengan topik kajian penelitian ini, kemudian dianalisis secara deskriptif.Kata-kata kunci: COVID-19, Maqasid al-Shariah, Shalat, Hifdz al-Din, Hifdz al-Nafs. AbstractThe spread of a deadly epidemic known as Covid-19 has indeed caused several polemics such as economic, social, political and religious issues in particular. For instance, the conflicts regarding ban congregational prayers and also mass gatherings amid coronavirus or Covid-19 pandemic have led to various responses pros and cons amongst the society. The pro assumes that it is indeed a way of preventing as well as anticipate the transmission of Covid-19. Unlike those who disagree with that kind of postponement, they presume that hifdz al-Din (protection of religion) is much more important than hifdz  al-Nafs (protection of life). Furthermore, the key main objective of this research is to describe the postponement or cancelation of Friday prayers and mass gatherings due to coronavirus pandemic based on comprehensive study of maqasid al-shariah. In this research, the researcher uses full qualitative method and documentation related to the topic of this research, which then will be analyze descriptively.Keywords: COVID-19, Maqasid al-Shariah, Salat, Hifdz al-Din, Hifdz al-Nafs.

The aim of this chapter is to identify various materials being used currently for antenna design classified as wearable materials. In the current scenario, no study was found where collectively all the available materials and their properties could be discussed including their pros and cons features. This chapter identifies various available materials on the basis of their characteristics, availability, and the methodology of fabrication being involved along with their corresponding properties. Post detailed study and analysis done in this research enabled us to broadly classify the materials as conductive and substrate materials. This brings to the understanding that earlier no such broader classification was made available, and hence, a comprehensive study would provide us better information availability on various wearable antenna materials.

AbstractFull Adder (FA) circuits are integral components in the design of Arithmetic Logic Units (ALUs) of modern computing systems. Recently, there have been massive research interests in this area due to the growing need for low-power and high-performance computing systems. Researchers have proposed a variety of FA cells with diverse design techniques, each having its pros and cons. As a result, a systematic method for performance comparison of FA cells using a common simulation platform has become necessary. In this work, we present an extensive study of FA cells. We have compared the performance of thirty-three (33) existing 1-bit FA cells. The drive powers of these FA cells have been compared by applying a variety of load conditions. In addition, the 1-bit FA cells have been extended to 32-bit structures to test their scalability and to investigate their performance in wide-word structures. We have determined that twenty-one (21) of the thirty-three (33) FA cells cannot operate in a 32-bit structure, even though some of them exhibit excellent performance as a 1-bit cell. The main finding of this research is that the single-bit performance parameters of FA cells should not be considered as the main basis for performance comparison. Any FA cell should be analyzed in a multi-bit structure to determine its practical effectiveness.

In our initial publication on this subject1) we reported results demonstrating that contrast is the most important factor in producing the high image quality required for reliable image analysis. We also listed the factors which enhance contrast in order of the experimentally determined magnitude of their effect. The two most powerful factors affecting image contrast attainable with sheet film are beam intensity and KV. At that time we had only qualitative evidence for the ranking of enhancing factors. Later we carried out the densitometric measurements which led to the results outlined below.Meaningful evaluations of the cause-effect relationships among the considerable number of variables in preparing EM negatives depend on doing things in a systematic way, varying only one parameter at a time. Unless otherwise noted, we adhered to the following procedure evolved during our comprehensive study:Philips EM-300; 30μ objective aperature; magnification 7000- 12000X, exposure time 1 second, anti-contamination device operating.

Comprehensive Study

Hexachlorobenzene (HCB), a persistent and mobile organochlorine pesticide, occurs in environment. HCB has been shown to be present in human follicular fluid. An objective of the present report, which is part of a comprehensive study on reproductive toxicity of HCB, was to determine the cytologic effects of the compound on ovarian follicles in a primate model.Materials and Methods. Eight Cynomolgus monkeys were housed under controlled conditions at Animal facility of Health and Welfare, Ottawa. Animals were orally administered gelatin capsules containing HCB mixed with glucose in daily dosages of 0.0 or 10 mg/kg b.w. for 90 days; the former was the control group. On the menstrual period following completion of dosing, the monkeys underwent an induction cycle of superovulation. At necropsy, one-half of an ovary from each animal was diced into ca. 2- to 3-mm cubed specimens that were fixed by immersion in 2.5% glutaraldehyde in 0.1 M cacodylate buffer (pH 7.3). Subsequent procedures followed to obtain thin sections that were examined in a Hitachi H-7000 electron microscope have been described earlier.

Comprehensive Study

As part of a comprehensive study of microstructural and mechanical response of metals to uniaxial and biaxial deformations, the development of substructure in 1100 A1 has been studied over a range of plastic strain for two stress states.Specimens of 1100 aluminum annealed at 350 C were tested in uniaxial (UT) and balanced biaxial tension (BBT) at room temperature to different strain levels. The biaxial specimens were produced by the in-plane punch stretching technique. Areas of known strain levels were prepared for TEM by lapping followed by jet electropolishing. All specimens were examined in a JEOL 200B run at 150 and 200 kV within 24 to 36 hours after testing.The development of the substructure with deformation is shown in Fig. 1 for both stress states. Initial deformation produces dislocation tangles, which form cell walls by 10% uniaxial deformation, and start to recover to form subgrains by 25%. The results of several hundred measurements of cell/subgrain sizes by a linear intercept technique are presented in Table I.
