Concrete is a versatile material and can be extended to applications requiring to perform in aggressive environments. In these environments, concrete should be highly durable for longer service life. The present thesis is an effort directed towards the achieving high performance in concrete by using RHA as supplementary cementitious material. To achieve high Strength in the concrete, it is necessary to have better understanding of the behavior of constituent materials. Thus, the behavior of RHA in concrete in terms of efficiency was assessed through the results available from literature. A mix design method was suggested and a wide range of concretes varying from 85-87Mpa with replacement levels varying from 0 to 15 Percentage were attempted. These concretes could be produced with the mixing, compaction, curing procedures conventionally used and with the available RHA. A maximum strength of about 86Mpa was obtained which compares well or was even better with the results reported hitherto in literature.

This thesis investigates the overlapping relationship between the community and English-language teaching in a descriptive manner. It sets out the various points of view and interpretations of linguistic scholars on the contentious issue of incorporating Culture into ESL/EFL classrooms. Although some accept that in today's globalized world, we must open our ESL/EFL learners to other cultures as part of their ESL/EFL learning, others disagree and dispute the value of doing so. Some are more radical, seeing it as linguistic hegemony that can be avoided. Including several observational findings, the present thesis also addresses the perspectives and views of scholars on the convergence of language teaching and community.

Spur dykes also known as Groynes are often used to either divert or attract the flow from the main structure to safeguard their life. Those structures may be bridge piers, abutments or any similar hydraulics structures. Spur dykes are also used to save the cutting of banks on concave side of stream. Lots of work have been done in recent past on spur dykes by many investigators in which various hydraulic and geometrical parameters of spur dykes such as discharge, sediment size, flow velocity, shear stress, spur dykes shape, size and submergence etc. are studied in detail. But mostly all the studies were pointed out in straight open channels. Very few studies were done in curved channel and only their similar effects were studied. In present thesis main emphasis is given to study the effect of orientation and location of spur dykes in meandering channel on the bed of downstream side. In the present study experimental work has been carried out in 80° bend and constant discharge (Q = 4.5 l/s) is allowed to pass in channel without spur dyke. It is found that maximum scouring occurs at angular displacement θ = 60° to 80° in the vicinity of outer bank. To minimize this scouring, spur dyke has been installed at angular displacement θ = 20°, 40° & 60° by changing the dyke angle α = 60°, 90° & 120° respectively. It is found that scouring at θ = 60° is reduced by installing spur dyke at angular displacement θ = 40° which is oriented at α = 60° and scouring at θ = 80° is reduced by installing spur dyke at angular displacement θ = 60° which is oriented at α = 60°.

The increased costs associated with baculovirus mass-production urge the search for synergistic products that reduce the amount of active matter. In the present thesis, a synergistic factor with great potential for baculovirus-based formulations was expressed and produced using a baculovirus expression system. The main achievement of the present thesis is that the in vivo production of solubilized enhancins using baculovirus-based expression systems can be used to improve the efficacy of biological insecticides against lepidopteran pests, reducing the active matter of bioinsecticides and making them commercially competitive with chemicals.

Abstract In design of concrete structures, concrete plays an important role in the contemporary background as raw material for construction has been decreased. Therefore construction industry has acquaint with novel methods by making use of the available waste material for partial replacement by using alternative aggregates instead of ordinary aggregates. In this study, pumice stone is used as replacement materials for concrete where it is found in the abyssal of the red clay or in deepest portion of the ocean, and partially replacing by Pumice, blends with cement. The physical, mechanical and durability properties of concrete was investigated by conduction compressive strength and tensile strength on the ordinary and replaced concrete with varied percentage of pumice from 5% to 30%. It’s obsereved that environmental and economical benefits can be achieved if waste materials can be used to replace the coarse aggregate in order to use the waste materials effectively in areas with abundant availability of materials. This thesis work on the effectiveness of partial substitutions of pumice for coarse aggregate in producing adequate strength gain. In the present thesis work comparison of fresh concrete and hardened properties of concrete for both conventional concrete and Replaced concrete for varying percentage of replacement of pumice stone to coarse aggregate and based on the experimental results, it’s concluded that 25% partial replacement by pumice gives maximum compresive strength.

The subject of this doctoral thesis is the Role of the World Trade Organization (WTO) in the Development of International Trade: History, Problems and Perspectives of International Trade law. The purpose of the present thesis is to explore the role of the WTO in the development of international trade, to research the possibilities of resolving trade disputes within the framework of the WTO law, to identify strengths and weaknesses of Dispute Settlement Understanding (DSU), to determine the status of a developing country and elaborate recommendations for the improvement of WTO legislation in compliance with fair trade. The present doctoral thesis consists of four chapters: The first chapter reviews international trade and main aspects of WTO legislation, analyses rules for international trade, defines strategy for WTO trade policy and the principles of legal pluralism and inter-legality, establishes correlation of norms of international law examines trade tensions and elaborates proposals for their solution. The second chapter, attempting to determine developing country status in the WTO, explores the categorization of a developing country by the World Bank, United Nations and International Monetary Fund (IMF). Experience of developing countries with enforcement of DSU rulings is analysed. Furthermore, application of more consultations and mediation at DSU is suggested as it would turn Dispute Settlement Body (DSB) into a more practical tool. This chapter also focuses on political stability and trade agreements as well as national security and cybersecurity which ensure the simplicity, stability and neutrality of trade agreements. The third chapter examines the peculiarities of legal status and overviews WTO disputes involving subsidies in the renewable energy sector that follows the WTO agenda. The fourth chapter reviews the trade policies and practices of Georgia as well as Georgia-WTO relationship in the historical context. The author retrospects trade relations between Georgia and Russia which, as the author qualifies, eventually developed into the “trade war” with a very clear political connotation and precedential character. This is the only and first attempt ever to analyse this case and to give it the qualification of “the trade war”. The present thesis consists of 196 pages and includes introduction, four chapters, conclusions, suggestions and interviews.

Language deficiency is one of the barriers that autistic children face in their language growth. Autistic children may face these difficulties in which they have trouble in understanding and communicating their language. Using Chaer's Language Disorders Theory (2003), this research attempts to investigate the receptive language disorders performed by an autistic child named Rahesa and the expressive language disorders performed by an autistic child named Rahesa based on Suherman’s (2016) theory. Using a qualitative with descriptive approach, the data were taken from the videos of the subject’s relationship with his mother, then transcribed into dialogs and analyzed. Then, researcher continued to describe all the findings. The findings of this research indicate that an autistic person has trouble interpreting the message of others and communicating his/her emotions by verbal words. An autistic boy has three difficulties with receptive language disorder, such as difficulty in interpreting verbal language, difficulty in following verbal guidance, and difficulty in focusing his mind.As far as expressive language disorder is concerned, an autistic person faces six difficulties, such as difficulty in inserting words into sentences, difficulty in choosing the correct expression, poor comprehension, taking words out of sentences, repeating some words or phrases, and inappropriately using language structure.The present thesis seeks to offer insights to prospective scholars who are interested in linguistic, in particular psycholinguistics concerned with language problems in the case of autism. General readers will enrich their understanding of and how to cope with the forms of language problems in autistic children.

From the beginning of Islam to date, the scholars interpreted the Holy Qurʾān, all over the world. They performed their responsibilities of explaining the Holy Qurʾān according to the circumstances. As result of this, they left massive heritage in the field of Tafsir. However a large number of these books could not be pupblished and vanished with the pasage of time and huge number of these scholarly works is available in two forms; published and manuscript. Libraries of Turkey, Kingdom of Saudi Arabia, Berlin, Leiden and Sub-continent, are proud to have antique manuscripts. Tafsir Talkhis-ud-Durar of Allama Abdul Hameed Bin Abdul Majeed Al-Hakimi (514 A.H) is one of the notable manuscripts scholarship in the field of Tafsir. The manuscript is available in Noor-e-Usmania Library, Istanbul, Turkey, which is famous for the preservation of Islamic literature. The manuscript of Tafsir Talkhis-ud-Durar, exists in one volumes of 425 sheets, each sheet contain two parallel pages. The language of the manuscript is Arabic, and scribe style is Arabic Naskh, while scribe used red color for Qurʾānic words and the black for the interpretation. This corpus of Tafsir is a valuable treasure of a well-learned and prolific brain of Allama Abdul Hameed Bin Abdul Majeed Al-Hakimi. He not only interprets the text of the Holy Qurʾān literally but also tries to relate the Qurʾānic message to the contemporary problems of his era, ranging from the life of individual to the broad spectrum of the collective sphere life. We may consider it among early interpretations of the Holy Qurʾān, which are far away from sectarianism and focus on message of the Holy Qurʾān and deal specifically with the social problems of the Muslims world. In the view of its important the Department of Tafsir and Quranic Sciences at the Faculty of Usuluddin, Internationa Islamic University made it a research project to be edited by four PhD students of the Department; the details are as follow: . Muhammad Esmaeel Haqani; from Sheet: 1 to 74 (Surah Al-Fatiha to Surah Al-Maida and first pard of the thesis containg introduction of the manuscript and the author and the scribe and mathodology of the author in detail.) Nasrullah tend to edit the manuscript of this interpretation and devided in to fifteen chapber beginning from Surah al-An’am to end of Surah Taha, (sheet no: 74 to 189 of the manuscript). The thesis also contains a a brief preface containing basic information about the manuscript, the scribe, the auhor and his mathodology in his Tafsir.

In the present thesis, the genetic variability of field-collected isolates of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) was examined. These results have revealed the great variability present within natural ChinNPV isolates, confirm the differences between two different genetic variants from these isolates and, more important, appear to identify the ChinNPV-K variant as a generator of variability in these isolates. In conclusion, a great variability has been revealed within ChinNPV natural isolates, with a single variant showing a key role in the generation of this diversity in a concentration-dependent manner.
