And Performance

Abstract The dynamics of a vehicle's tires is a major contributor to the vehicle stability, control, and performance. A better understanding of the handling performance and lateral stability of the vehicle can be achieved by an in-depth study of the transient behavior of the tire. In this article, the transient response of the tire to a steering angle input is examined and an analytical second order tire model is proposed. This model provides a means for a better understanding of the transient behavior of the tire. The proposed model is also applied to a vehicle model and its performance is compared with a first order tire model.

A Palestinian-Israeli poet declares a new state whose language, “Homelandic,” is a combination of Arabic and Hebrew. A Jewish-Israeli author imagines a “language plague” that infects young Hebrew speakers with old world accents, and sends the narrator in search of his Arabic heritage. This book brings together such startling visions to offer the first in-depth study of the relationship between Hebrew and Arabic in the literature and culture of Israel/Palestine. More than that, the book presents a captivating portrait of the literary imagination's power to transgress political boundaries and transform ideas about language and belonging. Blending history and literature, the book traces the interwoven life of Arabic and Hebrew in Israel/Palestine from the turn of the twentieth century to the present, exposing the two languages' intimate entanglements in contemporary works of prose, poetry, film, and visual art by both Palestinian and Jewish citizens of Israel. In a context where intense political and social pressures work to identify Jews with Hebrew and Palestinians with Arabic, the book finds writers who have boldly crossed over this divide to create literature in the language of their “other,” as well as writers who bring the two languages into dialogue to rewrite them from within. Exploring such acts of poetic trespass, the book introduces new readings of canonical and lesser-known authors, including Emile Habiby, Hayyim Nahman Bialik, Anton Shammas, Saul Tchernichowsky, Samir Naqqash, Ronit Matalon, Salman Masalha, A. B. Yehoshua, and Almog Behar. By revealing uncommon visions of what it means to write in Arabic and Hebrew, the book will change the way we understand literature and culture in the shadow of the Israeli–Palestinian conflict.

Zakat merupakan salah satu dari rukun Islam yang hukumnya wajib bagi setiap muslim untuk mengeluarkannya apabila sudah mencapai nisab. Dalam fungsi ekonomi, dana zakat memiliki potensi untuk mengentaskan kemiskinan melalui pengelolaan yang bersifat produktif. Kemiskinan seakan menjadi sebuah fenomena yang harus segera diatasi. Kemiskinan membuat kehidupan seseorang menjadi tidak mudah, karena adanya keterbatasan dalam pemenuhan kebutuhan sehingga berdampak pada kesenjangan sosial. Tingkat kemiskinan dan kesenjangan sosial dari beberapa wilayah di DIY masih cukup tinggi, kemudian permasalahan lainnya produksi ekonomi lokal berpotensi untuk berkembang, namun masih terkendala dalam segi permodalan. Lembaga Amil Zakat (LAZ) didirikan dengan tujuan untuk dapat mengelola zakat, infaq, sadaqah dan waqaf (ZISWAF) agar tepat sasaran dan tepat guna dalam penyaluran zakat. Penelitian ini bertujuan untuk mengetahui, menganalisis bagaimana peran RZ cabang Yogyakarta dalam menyalurkan dana zakat agar bisa berdampak dalam peningkatan usaha mustahiq.Penelitian ini merupakan jenis penelitian lapangan (Field Research), dimana penulis akan mengumpulkan data dengan melakukan studi mendalam (in depth study) untuk mengetahui pengelolaan zakat dan penyalurannya dalam bidang pemberdayaan ekonomi di RZ cabang Yogyakarta. Melalui pendekatan metode deskriptif-kualitatif untuk mengetahui seberapa besar peran zakat tersebut terhadap peningkatan usaha mustahiq. Pemberdayaan ekonomi dilakukan dengan membentuk wilayah binaan dalam konsep Intregated Comunity Development (ICD) di tingkat Kecamatan pada masing-masing individu atau member (isitilah nama mustahiq di RZ cabang Yogyakarta) yang berjumlah 16 di setiap Kecamatan yaitu Kecamatan Banguntapan, Kecamatan Danuerejan, Kecamatan Godean dalam waktu maksimal 3 tahun. Dari masingmasing Kecamatan di dampingi oleh 1 Member Relationship Officer (MRO) yang merupakan bagian dari karyawan RZ cabang Yogyakarta yang berfungsi sebagai pendamping, pemberdaya, surveyor pemberdayaan, penggerak lingkungan, serta advokat masyarakat.Dalam manajemennya RZ cabang Yogyakarta membentuk lembaga Mandiri Daya Insani yang berfungsi sebagai pengelola dalam bidang pemberdayaan ekonomi bertemakan senyum mandiri. Adapun program penyaluran yang dilakukan yakni berbentuk bantuan usaha yang terbagi dalam dua jenis,  pertama adalah sarana usaha seperti perlengkapan, dan peralatan usaha, kemudian yang kedua adalah modal usaha berupa uang yang jumlahnya berbeda-beda. Bantuan usaha yang diberikan tidak setiap bulan, walaupun dana turun dari RZ pusat setiap bulan untuk langsung disalurkan kepada mustahiq oleh MRO, hal ini yang membedakan karena tingkat kebutuhan mustahiq di wilayah binaan berbeda satu sama lain.Melalui pemilihan sample yang terbagi ke dalam tiga sektor usaha mustahiq yaitu produksi, perdagangan, dan bisnis catering, maka penulis memperoleh data berjumlah 9 mustahiq dari 3 wilayah binaan yang memberikan keterangan mengenai kondisi usahanya. Dengan keterangan data primer yang diperoleh melalui wawancara dan observasi, kondisi usaha seluruh mustahiq yang diteliti sebelum menerima bantuan usaha memiliki pendapatan rata-rata Rp 15.000 s.d Rp 200.000 dan masih digunakan untuk perputaran modal untuk menjalankan usahanya. Kemudian setelah masing-masing mustahiq mendapatkan bantuan usaha dari RZ cabang Yogyakarta, keseluruhan mustahiq bisa meningkatkan pendapatan dengan prosentase kenaikan rata-rata 50%.s.d 100% dari kondisi usaha sebelum diberi bantuan dengan jumlah pendapatan rata-rata Rp 20.000 s.d Rp 700.000 berjumlah 6 mustahiq, kemudian pendapatan usaha diatas Rp 1000.000 berjumlah 3 mustahiq. Dengan demikian program pengelolaan zakat dalam bidang pemberdayaan ekonomi yang dilaksanakan oleh RZ cabang Yogyakarta melalui penyaluran bantuan usaha mampu memberikan pengaruh yang cukup baik terhadap kondisi usaha mustahiq sebelum dan sesudah diberi bantuan.

This study examines the reasons for Achehness Ulama of Dayah regarding plants and seeds that are subject to zakat. How the logic of thinking used by these ulama and their relationship with maqāṣid al-syarī‘ah (syariah legal purposes). This research focuses on the legal substance of zakat as intended by the Qur’an and Hadith, then it is analyzed from the side of maqāṣid al-syarī‘ah. The results of this study indicate that Acehnese Ulama argues that zakat of plants is only rice or a kind of staple food, on the grounds that it is a staple food of a country’s population, which has filling properties and can be stored and lasted. Other plants such as oil palm, cocoa, coffee, even though they are productive they are not zakatable wealth, because they do not meet these criteria. The legal reasoning of the Acehness Ulama uses the deductive method with the bayani (language) approach. On the other hand, the Acehness Ulama does not deny that the search for maqāṣid al-syarī‘ah can be done through in-depth study, but it is not yet certain that the obligations of zakat on productive plants can be formulated through this approach, so they reject it. According to them, the command of zakat can only be understood from the side of ta‘abbudī (worship approach), not through ta‘aqqulī (resourceful approach).

<div>Electrochemical reduction of CO2 to useful chemical and fuels in an energy efficient way is currently an expensive and inefficient process. Recently, low-cost transition metal-carbides (TMCs) are proven to exhibit similar electronic structure similarities to Platinum-Group-Metal (PGM) catalysts and hence can be good substitutes for some important reduction reactions. In this work, we test graphenesupported WC (Tungsten Carbide) nanocluster as an electrocatalyst for the CO2 reduction reaction. Specifically, we perform DFT studies to understand various possible reaction mechanisms and determine the lowest thermodynamic energy landscape of CO2 reduction to various products such as CO, HCOOH, CH3OH, and CH4. This in-depth study of reaction energetics could lead to improvements and develop more efficient electrocatalysts for CO2 reduction.<br></div>

<div><div><div><p>Vaccines have an innate tendency to lose their structural conformation upon environmental and chemical stressors. A loss in conformation reduces the therapeutic ability to prevent the spread of a pathogen. Herein, we report an in-depth study of zeolitic imidazolate framework-8 (ZIF-8) and its ability to provide protection for a model viral vector against dena- turing conditions. The immunoassay and spectroscopy analysis together demonstrate enhanced thermal and chemical stability to the conformational structure of the encapsulated viral nanoparticle. The long-term biological activity of this virus-ZIF composite was investigated in animal models to further elucidate the integrity of the encapsulated virus, the bio-safety, and immunogenicity of the overall composite. Additionally, histological analysis found no observable tissue damage in the skin or vital organs in mice, following multiple subcutaneous administrations. This study shows that ZIF-based protein composites are strong candidates for improved preservation of proteinaceous drugs, are biocompatible, and capable of controlling the release and adsorption of drugs in vivo.</p></div></div></div>

In India, traditionally and from time immemorial, marriage has always been a sacred bond for people of this country. The aim of this study is to explain a socially sanctioned sex relationship involving people of two opposite gender whose relationship is expected to endure beyond time required for gestation. The functional method of the study has been set up on the field-based observation to find out the reasons behind rising of marital disharmony among working couples. But the problem is initially in modern times the concept of marriage is gradually taking a different turn between couples. Hence the focus of this paper is to study the various factors giving rise to marital disharmonies among working couples in urban India and how these discords can be solved so that couples can lead a happy harmonious married life ahead. Survey has been done in the city of Kolkata taking people from various walks of life. As Kolkata is one of the major Metropolitan cities of India it was easier to find people belonging to different professions. The result of this study is every marriage brings challenges in life. Maximum working couples are losing attachment with each other as they have lack of time for each other. Bringing work at home, sharing of parenthood, indifference towards each other, lack of adjustments are the causes for which level of disharmony is increasing.

Education for sustainable development (ESD) enjoys a huge momentum worldwide in which the role of teachers for making sustainable development goals a reality has been recognized significantly. Teachers through their knowledge, attitudes and skills can bring the learning about these concepts to the curriculum and class room interaction and are in a position to influence their students. Therefore it is pertinent, that teachers are sensitised towards these issues, so that they prepare and nurture their students for making appropriate and responsible choices which contribute to a sustainable future. At this juncture it becomes crucial to understand their priorities and awareness level in context of the sustainable development. The present research paper aims to analyse the perception of forty post graduate pre-service teachers of the Chandigarh region, towards ESD through the dimensions of economic sustainability, environmental sustainability, social sustainability and cultural sustainability. For this researchers have adopted qualitative content analysis methodology for an in-depth study of the subjective responses through an open ended question. The findings suggest that most of the respondents associated the perception of ESD strongly with environmental sustainability. It is noted that the pre-service teachers lack a holistic approach towards ESD. On the basis of the findings it is recommended that there is an urgent need of integrating the concept of ESD consciously and conscientiously in India’s teacher education programmes.

The book under review is a concise but fairly in-depth study of the prospects for export diversification from the Less Developed Countries (henceforth labeled as LDCs) particularly to Developed Countries (henceforth labeled as OCs). Given the multiple problems faced by the LOCs in exporting to the OCs - protectionist policies with regards to manufactured exports, volatility of prices obtained for raw material exports, etc. - the study analyses the potential for following an intermediate route. The important issues in the export of semi -processed and wholly processed raw materials are discussed. 111ese issues range from the problems and potentials for the location of processing facilities in the LOCs to the formulation of appropriate policies to encourage an export of processed goods rather than raw materials. Such policies will be useful both in solving the balance of-payments problems of the LDCs and in attaining the goal of the Lima Declaration and Plan of Action on Industrial Development and Co-operation, that called for 2S percent of world industrial production to be located in the LOCs by the year 2000.
