Ceramic Waste Powder for Eco-Friendly Self-Compacting Concrete (SCC)
Authors: Aly Sama T. , El-Dieb Amr S. , Taha Mahmoud Reda 
Published: August 2018

Abstract
Self-compacting concrete (SCC) was developed in the 1980s in Japan and has since received wide attention and use in the construction industry worldwide. Numerous investigations have been conducted on SCC to establish comprehensive knowledge of its mixture requirements and performance. The use of high powder content, mostly cement, is one of the SCC mixture’s requirements, although it is not desirable, as it will increase the cost and has other negative environmental effects. The use of industrial solid waste materials such as slag, fly ash, and limestone powder as fillers in SCC has proven to be a successful way of solid waste recycling without impairing SCC properties. Ceramic waste powder (CWP) produced during the manufacture of ceramic tiles is dumped in landfills and will cause soil, air, and groundwater pollution which pose a serious problem on the society. The use of CWP as a partial replacement of portland cement in SCC can convert the landfilled waste material to a valuable ingredient and will also contribute to the reduction in the overall energy consumption and CO2 emission accompanying the production of portland cement. In this study, the utilization of CWP, in large quantities, as a partial cement replacement in making SCC will be evaluated. Its effect on hardened concrete properties, durability characteristics, and microstructure development is studied. It is found that CWP can be used successfully to partially replace cement in large quantities to produce eco-friendly SCC.
Creating Tensile Fractures in Colorado Shale Using an Unconfined Fast Heating Test
Authors: Li Biao , Wong Ron C. K. 
Published: August 2018

Abstract
Under a high heating rate, thermally induced pore pressure is readily developed in low-permeability soft mudrocks, such as clay shale. Thermally induced pore pressure may lead to tensile fracturing in soft mudrocks and pose severe issues for thermal projects that include thermal heavy oil recovery and radioactive waste disposal. This article presents experimental investigations on the possibility of creating tensile fractures in a clay shale (Colorado shale) sample using a fast heating test. An unconfined fast heating test was conducted on a Colorado shale sample, which was retrieved from an overburdened shale formation above oil sand reservoirs in the Cold Lake area in Alberta, Canada. X-ray computed tomography scanning was applied to observe the thermally induced tensile fracturing behavior. A fully coupled thermal-hydromechanical finite element analysis was performed to examine the thermally induced pore pressure development in the sample. Experimental work indicates that Colorado shale loses its integrity when the sample’s pore pressure is higher than its tensile strength. The generated fractures in Colorado shale are almost parallel to shale’s intrinsic bedding plane.
Fatigue Characteristics of Coal Specimens under Cyclic Uniaxial Loading

Published: August 2018

Abstract
To investigate the fatigue failure of coal under uniaxial stress, multilevel cyclic loading tests on cylindrical coal specimens were conducted in a laboratory using the MTS815.02 rock-mechanics test system (MTS Systems Corporation, Eden Prairie, MN). Specimens were tested for as many as 1,500 loading cycles under each cyclic loading session. From these tests, the following conclusions can be drawn. The peak stress of cyclic loading has a significant effect on the coal specimen’s fatigue behavior. When the peak stress of cyclic loading is less than the coal fatigue strength, the coal specimen’s deformation stops increasing after a certain number of loading cycles, and the number of acoustic emission (AE) counts is low. When the peak stress of cyclic loading exceeds the coal fatigue strength, the axial, circumferential, and volumetric strains and the energy dissipation exhibit the same progression through three phases: a primary phase, a steady phase, and an acceleration phase. The region division of the three phases of the strain and energy dissipation evolution is coincident. The AE activity also exhibits three phases: an active, a quiet, and a very active phase. In the very active phases, numerous AE signals exist when the stress is at its peak, but no AE signals exist near the stress minima. Coal specimens that are subjected to conventional uniaxial compression tests and specimens that are deformed by cyclic loading tests fail in very different ways. The former specimens fail mainly because of a single inclined shear plane, whereas the latter specimens are reduced to a mound of small fragments.
A Functional Bleeding Test Apparatus for Concrete
Authors: Gökçe H. Süleyman , Andiç-Çakır Özge 
Published: August 2018

Abstract
Bleeding is one important indicator that is related to the physical and mechanical properties of fresh and hardened concrete. Standards generally prefer methodologies that are similar to one another to measure the bleeding of fresh concrete. The preferred test apparatus used in the standards is troublesome because it requires a manual test procedure and repeated measurements until final setting of the fresh concrete. The functional bleeding test apparatus presented in this study will ease test performance and eliminate the faults caused by the test procedure and the experimenter.
An Experimental Validation on Adaptive Controllers in Tracking and Smoothening of Wind Power for a Variable-Speed System
Authors: Pragaspathy S. , Anand B. 
Published: August 2018

Abstract
The ever-increasing demand for conventional energy sources has driven society toward more research and development in alternate energy resources and the importance of a sustainable environment. Among renewable resources, wind energy plays a prominent role as a source of electrical energy and has emerged as one of the leading green energy technologies with an annual average growth rate of 30 % across the globe. Though the impact has a clear vision when compared to previous decades, its aftereffect concerning the quantity and quality of power output receives a significant amount of interest on the wind energy scenario. This article presents an advanced control strategy to extract possible peak power and to explore fluctuation as less controlled output for a permanent magnet synchronous generator–based variable-speed wind turbine system through adaptive peak power tracking controllers. A substantial voltage of ripple magnitude is derived to suppress the double line frequency ripples that exist between the dc-dc and dc-ac converters. The significant harmonic disorders are analyzed using Fast Fourier Transformation, and the elimination of the same is ensured by introducing appropriate harmonic trap filters. The output power is exercised accordingly with the help of a standalone energy storage unit and thereby power management is performed for the proposal. The control strategy ensures the appropriate selection of power source selection controllers, and the analysis reveals the prominent working of a standalone energy storage system in the typical area of requirements. The experimental validation is made with the prototype model from the laboratory experimentation, which is identical to the simulation platform.

Background: The optimal treatment strategy in patients presenting with hemodynamically significant carotid artery disease who are to undergo cardiac surgery, remains controversial. In this study, we retrospectively analyzed the outcome data of patients receiving synchronous or staged coronary artery bypass graft (CABG) surgery and carotid endarterectomy (CEA).
Methods: Between 2011 and 2016, 3173 patients underwent CABG surgery in our institution, of whom 323 received CABG and CEA either as synchronous (N = 307) or as staged (N = 16) procedures. Patients´ characteristics, peri- and postoperative data were collected from our digital medical database. Propensity score matching was used to match each patient from the staged group to two appropriate patients (1:2 matching) from the synchronous group (synchronousmatched).
Results: The overall incidence of ischemic stroke (IS) and transitory ischemic attack (TIA) was 4.9% and 5.6%, respectively. No hemorrhagic stroke was noted in both groups. Incidence of IS did not differ significantly between matched groups (P = 1.000). Significantly higher rates of postoperative neurological complications, such as TIA and delirium, were found in the synchronousmatched group (P = .041 and P = .043, respectively) compared with the staged group. Additionally, there were more postoperative respiratory insufficiencies in the synchronousmatched group (P = .043). Thirty days mortality did not differ significantly between the matched groups.
Conclusion: In this experience combined with the data given in literature, our findings suggest a possible superiority of the staged CABG/CEA approach. Large, randomized studies are required to verify our findings and to establish applicable guidelines.

Steven Johnson syndrome is a life threatening clinical condition that is usually manifested with fever , rash, bullous formation, oral and ocular lesions and genital and anal lesions. This syndrome, in majority of cases begins with influenza-like symptoms and continues with a red rash and blisters . Then the top layer of the affected skin dies and sheds.[1,2] This case report is about a 28 year old male patient who was referred to the Infectious Disease Hospital of University Hospital Center Mother Theresa Tirana with the suspected diagnosis of Hemorrhagic Fever. The patient referred 5 days of continuous fever, malaise, rash, myalgia, headache, and nausea As soon as the patient was admitted, we immediately performed specific serologic tests, therapeutic regimen for the suspected diagnosis of hemorrhagic fever and complementary examination. During the first 10 hours, we noticed that the rash became more intense and other skin lesion and bullous formation appeared. The patient was admitted in ICU and initial diagnosis of Steven Johnson Syndrome was made. This case report elaborates the particular clinical appearance and the misdiagnosis that was associated with Steven Johnson Syndrome.[3] Specific conditions as the prolonged prodromal phase of SJS, the strong epidemiological data for hemorrhagic fever, the absence of information for misuse of drugs led us towards a “sure diagnosis” in the first place. However, the close follow-up in the ICU revealed new clinical signs and rapid differential diagnosis was done. Due to the intensive care therapy, which was applied for Hemorrhagic fever at first place, we managed to overcome complications and safe the patient life.[4]

Authors: Halima Sarkinfada 
Published: August 2018

This paper focuses on prospects and problems of the use of mother tongue as medium of instruction for the whole duration of primary education in the North Western States of Nigeria. The language of instruction is very crucial to education at every level because it serves as the key to learning. Mother tongue serves as the first language of children. Low trend of enrolment in primary school has been attributed to the use of foreign language of instruction in schools which is contrary to the customs and traditions of the people in the North Western states of Nigeria. Pupils find it difficult to socialize with the English language and do not have a sense of belonging in school. The research intends to examine the prospects and problems of the use of mother tongue as a medium of instruction for pupils in North west Nigeria. The study adopted descriptive survey design. The instrument for this study was a self-develop questionnaire titled "Questionnaire on prospects and problems Mother tongue". The population of the study include stakeholders' in the society, which include parents, Guardians, and Teachers, involved in childhood education. A total of 907 participated in the study, 113 parents, 30 Guardian, and 764 Teachers, Stratified sampling technique was used to select 3 States from 7 North-western states. Which include Katsina, Kebbi, and Sokoto states in North West Nigeria.. Ten (10) metropolitan primary schools were selected from the 3 states using simple random sampling technique. Since there no significant difference between the views of parents, teachers and other stakeholders on the prospects of the use of mother tongue as a medium of instruction for pupils in North West Nigeria. It is therefore recommended that since the prospects of Mother tongue ate inevitable and its challenges are inherent. Teachers, parents and all stakeholders should be more proactive in discharging their professional functions in teaching of Mother Tongue and the English language currently during lessons.
The Role of the Former combatants’ reintegration on promotion of inclusion and equity in Mt. Elgon region, Kenya
Authors: Wamocha Lydiah 
Published: August 2018

The social reintegration of former combatants is the most important aspect of the disarmament, demobilization and reintegration (DDR) process. Post conflict societies are marked by their past traumas long after the interest of most outsiders has ebbed. Reintegration understood in this context, speaks to societal transformation, which both takes time and is prone to setbacks long after peace has formally been declared. The purpose of the study was to investigate the role of reintegration of former combatants on promotion of inclusion and equity. The objective of the study was to explain the role of the former combatants’ reintegration on promotion of inclusion and equity in Mt. Elgon region. The desistance theory was used in the study. The study used the cross sectional descriptive survey design. The population of the study comprised former combatants, Sub County Commissioners, peace committee members, religious leaders and NGOs. The respondents comprised former combatants, sub county commissioners and peace committee members, religious leaders and NGOs. The stratified and purposive random sampling technique was used to select a sample of 150 former combatants, Three Sub County commissioners and 16 peace committee members, five religious leaders and Four NGO members. Data was collected by use of questionnaires, interviews and Focus Group discussion. In order to ascertain validity, the questionnaires and interview schedules were given to experts who matched all the items with the research questions to ascertain whether the instruments would measure all that it is supposed to measure. The reliability of the instruments was determined through test retest of the instruments. Data was analyzed by use of descriptive statistics of frequencies and percentages. Data from in-depth interviews was audio taped and transcribed. The transcripts were then organized into themes and categories as they emerged from the field. The findings of the study were presented descriptively. The findings of the study showed that: in the context of social reintegration the three dimensions of family and community; sustainable employment; and civic responsibilities should be given proper attention: to achieve the goal of reintegration there should be a major shift in the contemporary DDR approach by moving from the insertion approach towards a social reintegration one; community support is essential for the successful reintegration of former combatants and the sustainable social and economic reintegration of former combatants should be the ultimate objective of disarmament and demobilization and reintegration (DDR). Consequently, the study recommends that the government should budget for and give priority to the reintegration programmes so that they are fully completed instead of leaving them at the reinsertion stage; the communities take the lead in proposing community- based solutions for the issues identified.
