Renewable resources gained more attention in the last two decades due to persisting energy demand coupled with decrease in fossil fuel resources and its environmental effect to the earth. In this work, two cases of hybrid system will be studied. The first one dr. Jawad's home (Assistant professor in Electrical Engineering Department- University of Basrah). It is located in Al-Jazeera area that adjacent to the coast of the Shatt al – Arab that is located about 34 km south of the city center and its coordinates are (30.12° N, 47.49° E) latitude and longitude respectively. He used a hybrid system consist of (PV panels-batteries and the wind power will be studied theoretically by suggests a 4.5kW) wind turbine system) to feeding home's load. The second case study is the laboratories of the Department of Electrical Engineering-University of Basrah.The Department located in Garmat Ali district (part of Al-Hartha area) that is located in the north east of Basrah city and its coordinates are 30.582° N latitude and 47.76° E longitude. The hybrid system that used in this department consists of (PV panels-batteries). Results showed from first case study that the total power saving when using hybrid system resources in the house that consume 33.24 MWh/year about 31.3% by providing 10.4 MWh/year. Through the study of the laboratories of the Department the results show that is possible to operate many electrical appliances at the same time depending on the hybrid system such as fans, lighting, and computers and it is noted that the air conditioners can be operated by using more and more solar cells and batteries.

This chapter uses two case studies to explore how historians study language movement and change through comparative historical linguistics. The first case study stands as a short chapter in the larger history of the expansion of Bantu languages across eastern, central, and southern Africa. It focuses on the expansion of proto-Kafue, ca. 950–1250, from a linguistic homeland in the middle Kafue River region to lands beyond the Lukanga swamps to the north and the Zambezi River to the south. This expansion was made possible by a dramatic reconfiguration of ties of kinship. The second case study explores linguistic evidence for ridicule along the Lozi-Botatwe frontier in the mid- to late 19th century. Significantly, the units and scales of language movement and change in precolonial periods rendered visible through comparative historical linguistics bring to our attention alternative approaches to language change and movement in contemporary Africa.

The study investigates apartment’s façade thermal performance with neo-minimalist architectural style in Penang, Malaysia. Neo-minimalist style is considered as the most popular style in Malaysia in 2010s. The style is rediscovering from early modern minimalist movement with a design concept “less is more”. It applies minimal and efficient design of architectural character in defining form and space. Penang Island the second most important city in Malaysia after Kuala Lumpur. It is located at the north-western part of the country. The first case studies is the Light Linear apartment which has sixteen stories located on the east cost of Penang Island at Pantai Street, Penang. The second case study is BayStar apartment building, the eleven stories building tis located in Bayan Lepas at the seaside facing Jerejak Island. In order to conduct this study Fluke Ti20 thermal imager was used to capture thermal images for the west facades of the selected case study hourly from 12:00 to 6:00 pm on 15th March 2017. The study finds that the recessed wall, balconies and the shading devices were the important elements to provide shades on the façades for good thermal performance.

The intellectual capital in its dynamic approach focusses on the development of the entropic model, which expresses the dynamic transformation of the theoretical intellectual capital in a concrete and useful intellectual capital. The aim of the present paper is to perform a detailed analysis of the intellectual capital inside the SMES of the North-Est region of the country. It also speaks about the influence of the main integrators of the intellectual capital, divided into three elements: the cognitive, the emotional and the spiritual capital, about how they are acting as a field of forces upon the basic components of the intellectual capital, such as knowledge, intelligence and values and how they determine the generation and development of the intellectual capital in the eastern analyzed SMEs. Both jobs and teams inside the analyzed SMEs are stimulating the development of the intellectual skills, which reduces the need for involving the external experts, by appealing only those specialists who could transform the tacit knowledge into explicit knowledge. The organizational communication provides the necessary information and contributes to the establishment of a fair climate and of the effective relationships between managers and employees, between work mates, and also with the people outside the organization.

Chapter 4 analyses the possible legal recognition of insurgent justice by other actors, using the judicial practice of three independent Kurdish non-state armed groups in the Middle East as a case study. The Partiya Karkerên Kurdistan (PKK, Kurdistan Workers’ Party) has been engaged in a bitter armed struggle with Turkey since 1984, with rear bases in northern Iraq and Syria. The Partiya Yekîtiya Demokrat (PYD, Democratic Union Party) is a Kurdish insurgent group that joined the anti-Assad uprising of 2011 and now controls parts of the north-east part of Syria, in a precarious coexistence with the Syrian government. Finally, the Kurdish Regional Government (KRG) has operated independently since 1991 and remain in a military standoff with the central Iraqi government. All three Kurdish groups operate courts at trial and appeal levels, for civil and criminal matters. The chapter considers the possible application of the principle of complementarity under the Rome Statute in relation to a prosecution before the courts of a non-state armed groups. Likewise, the right or duty of third states under international law to give recognition to the operation of insurgent courts is examined. More radically perhaps, there is a possibility that even the territorial state might in some cases give legal effect to rebel court decisions. Finally, the Kurdish courts offer examples in which one non-state armed group is confronted with the need to determine the validity of the decisions of courts of other armed insurgents.

This chapter explores the rise of the concept of employability and how it has influenced policy and practical interventions to address unemployment. It explores how the concept has been understood as a threshold for labour market readiness or as a process of continual skills development necessary in a flexible labour market. It argues that employability is frequently utilised in neoliberalising forms of governmentality, shifting responsibility of gaining work onto the individual, rather than considering the various external and structural factors that affect employment prospects. A case study of an employability programme in the North East explores the practices through which the discourse of employability acts upon individuals.

Feasibility of the Sar Technique on Quartz Sand of Terraces of NW Himalaya: A Case Study from DevprayagOptically Stimulated Luminescence (OSL) dating technique based on the Single Aliquot Regenerative dose (SAR) protocol is being used increasingly as a means of establishing sediment burial age in the late Quaternary studies. Thermal transfer, low and changing luminescence sensitivity of quartz grains of young sedimentary belts of the New Zealand Alps and the north-east Himalaya poses problems in using SAR protocol. Records of active tectonics and signatures of palaeo-climate are preserved in the Quaternary - Holocene terrace sediments. Therefore, to unfold the history of successive tectonic and palaeo-climate events, robust chronological technique is needed. Palaeoflood deposits in NW Lesser Himalayan region receive quartz from the weathering of various rock types such as quartzite and phyllite in the Alaknanda Basin. A series of tests e.g. dose recovery, preheat plateau, thermal recuperation and change in sensitivity, were performed to check the suitability of quartz grains collected from the terrace sediment of Devprayag of the NW Himalaya, for OSL studies. Inferences were drawn regarding the source of the quartz grains on the basis of the geochemistry and luminescence intensity of the terrace sediment. The study shows that though quartz from the North West Himalaya are low in luminescence intensity but the reproducibility of De value makes the quartz sand suitable for SAR dating technique. Relation between luminescence intensity with CIA values help to predict the provenance of quartz sand. Tests show that the quartz from NW Himalaya is suitable for SAR protocol in OSL.
