There has been a varied advancement in the English language teaching materials for second language learners. Even though materials are in abundance, poetry seems to lack its appropriate usage in the process of second language teaching. Traditionally poetry may have lost its function as an attractive tool to impart novelty in teaching a language; the present study focuses to teach the four basic language skills and the linguistic role in learning English Language through poetry. Teaching second language through poetry is effectual since it made the learners to stir out their own insightful thinking and to stimulate their creativity. The interpretative ability of the learners had a gradual increase when a few lines were given to interpret. Thus the paper suggests that poetry is very beneficial for the teachers of English in second language learning classrooms.

This study examines to analyze and compare errors of concord students often conflict when speaking or writing essay. The comparison was made after 4 month of first term, examination in the case of the SS1 and SS3 classes respectively. The respondents were made up of Senior Secondary one (SS1) and Senior Secondary three (SS3) classes of Ogbemudein Mixed Senior Secondary School, Agbor, Delta State, Nigeria. Both respondents were asked to write an essay twice with four months interval on the same topic. In each writing sessions, there were 60 essays written by respondents, giving a grand total of 120 essays being analyzed. The results showed an increase in errors resulting to 3.40% among students in the senior secondary one (SS1) but with drastic reduction of 10.48% among the Senior Secondary three (SS3) which of course performed below expectation.

The study focuses on work family conflict of expatriates. Extending the prior work on work family conflict, applying role theory and conservation of resource theory, the paper presents a theoretical framework regarding situations and conditions specifically related to expatriates that can contribute to their work family conflict as prior work on expatriates is scarce in this particular research domain. It investigates the influence that issues like role novelty, cultural novelty, spousal adjustment, and education facilities may have on the work family conflict of expatriates. The study also postulates the probable moderating role of personality traits in the relationship between these issues and work family conflict being experienced by expatriates.

Light sequencer is a phenomenon which has been with us since the end of Second World War. Even though it has undergone very robust modification from the mirror balls into pure electronics. The 8051 microcontroller based light sequencer incorporates the programmable capability of the 8051 microcontroller in light sequencing light. This therefore has the advantage of changing the display of lights required as opposed to changing the whole electronics of the system of non-8051 microcontroller based light sequencer for the same effects lighting.

The increasing viability of 3D silicon integration technology has opened new opportunities for chip architecture innovations. One direction is in the extension of 2D mesh based chip multiprocessor architecture into three Dimensions. We present an efficient architecture to optimize system performance, power consumption, and reliability of stacked mesh 3D NoC is proposed. Stacked mesh is a feasible architecture which takes advantage of the short inter-layer wiring delays, while suffering from inefficient intermediate buffers. To cope with this, an inter-layer communication mechanism is developed to enhance the buffer utilization, load balancing, and system fault-tolerance. The mechanism benefits from a congestion-aware and bus failure tolerant routing algorithm for vertical communication.

Deck- drain samples obtained from five oil wells in the Niger Delta Basin of Nigeria were analyzed using Atomic Absorption Spectrophotometer (AAS), digital meters , American Standard and Testing Materials. The results shows that the pH of the deck-drain samples varies from 5, 10 to 5.4 while the total dissolved solids(TDS) varies from 4,585 to 27,170 mg/l. The electrical conductivity varies from 7,054 to 21,277µS/cm while the chloride content varies from 4 ,000 to 4,400mg/l. The H2S concentration ranges from 1.10 mg/l. These values do not conform with the Nigerian Department of Petroleum Resources (DPR) effluent water standard and thus constitute a threat to the environment. The result also show that the deck-drain samples are hard and contains high concentrations of calcium and sodium. The concentrations of the major cations in decreasing order is: Na+ > Ca2+ > Mg2+ >. K+ while that of the anions is: Cl- > HCO3- > SO42- > NO3- implying that the fluid type is NaCl. The pollution index (PI) of the samples varies from 17.81 to 42.47; this is in excess of the PI critical value of 1 and thus confirms high rate of degradation of the deck-drain samples.. The Sodium Adsorption Ratio (SAR) values of the samples ranges from 28.04 to 28.97 indicating that the deck-drains are poor for irrigation purposes. Piper and Stiff diagrams shows that the deck-drain samples exhibits the same chemical trend and model. Although, the deck-drain samples contains high concentrations of pH, TDS, electrical conductivity, H2S, Cl-, Ca2+ and Na+ ; these parameters can be treated and reduced to tolerable levels using soda ash, reverse osmosis , electro dialysis and aeration methods thus preventing soil and water pollution which can arise from the discharge of untreated deck-drains into these environments.

One of the most challenging problems encountered by a fluidized-bed designer is assessing how changes in bed geometry and operating conditions affect the gasifier performance while scaling up to demonstration / commercial size. Typically, commercial gasifier designs are based on operating experience from small pilot plants. A cold model of a gasifier represents an inexpensive and convenient platform for conducting detailed hydrodynamic studies that would otherwise be impossible in the hostile high pressure and temperature environment of fluidized bed gasifier. A perspex three dimensional semicircular cold model test rig of ID 940mm which is hydro dynamically scale down model of a demonstration plant of 168 TPD pressurized fluidized bed gasification (PFBG) plant is established and hydro dynamic parameters viz Froude no., bubble rise velocity, and bubble diameter are presented which are used for further scale up. Besides performance of the gasification process involves knowledge of dynamics of two phases viz. solid (coal) and gaseous for scale-up of the gasifier. The measurement of mean residence time (MRT) and degree of axial mixing of solid phase is required for evaluation of PFBG .The paper presents the residence time distribution (RTD) studies carried out in a pilot scale hot model of PFBG of 200 mm dia and verified in a hydro dynamically similar cold model .The coal particles labeled by radio tracer Lanthanum -140 was used to measure RTD by collimated scintillating detectors located at ash extraction points at the bottom and gas outlet at the top of the gasifier .The measured RTD data of coal / ash particles were treated and normalized for arriving at the mean residence time (MRT). The treated RTD data were simulated using gamma distribution model and found that model predicated MRTs of cold and hot model tests were in good agreement. The paper suggest the parameters which assist to minimize the bypassing of the coal particles in the gasifier thus improving the carbon conversion efficiency and hence enable scale-up of the PFBG.

A thorough understanding of adolescence in today’s society depends on information from various perspectives, most importantly from the areas of psychology, biology, history, sociology, education and anthropology. Within all of these perspectives, it is safe to say that adolescence is viewed as a transitional period whose chief purpose is the preparation of children for adult roles. During this transition period, adolescence people are facing many challenges due to the incredible changes in physically, mentally, emotionally, intellectually and psychologically. Due to the gender, adolescent girls’ challenges in the above aspects are higher only. The present study investigates almost all the relevant factors that are acting as the challenges faced by adolescent girls in the present social and educational scenario. A cognitive map shows a representation of how humans think about a particular issue, by analyzing, arranging the problems and graphically mapping concepts that all interconnected. In addition, it identifies causes and effects and explains causal links with exact degree [1]. As the problems of adolescents’ belong to an unsupervised data, the most suitable tool is Fuzzy Cognitive Map (FCM) which is the cognitive map with fuzzy degree. Hence analyzing the problems of adolescent girls by giving structured and organized outline of the appropriate factors and revealing the most important and other impactful factors is the objective of this study. In this manner, this study guarantees that its results are much more useful for psychologists, physiologists, educationists, adolescent girls and their parents to understand the problems that adolescent girls really facing in the present scenario.

In last two decades continues increase of comput-ational power and recent advance in the web technology cause to provide large amounts of data. That needs large scale data processing mechanism to handle this volume of data. MapReduce is a programming model for large scale distributed data processing in an efficient and transparent way. Due to its excellent fault tolerance features, scalability and the ease of use. Currently, there are several options for using MapReduce in cloud environments, such as using MapReduce as a service, setting up one’s own MapReduce cluster on cloud instances, or using specialized cloud MapReduce runtimes that take advantage of cloud infrastructure services. Cloud computing has recently emerged as a new paradigm that provide computing infrastructure and large scale data processing mechanism in the network. The cloud is on demand, scalable and high availability so implement of MapReduce on the top of cloud services cause faster, scalable and high available MapReduce framework for large scale data processing. In this paper we explain how to implement MapReduce in the cloud and also have a comparison between implementations of MapReduce on AzureCloud, Amazon Cloud and Hadoop at the end.

Brain is a highly vascular organ and receives about 15% of cardiac output. The Circle of Willis (CoW) or Circulus arteriosus is a ring-like arterial structure located at the base of the brain. The circle of Willis has its greatest significance in collateral circulations of the brain specially in old people who may have reduced brain blood supply due to senile arteriosclerosis. Materials and methods: The study was therefore conducted on 20 brains obtained during routine anatomical dissection in the department of Anatomy. The formative pattern of the circle of Willi’s external diameters of internal carotid arteries were measured, length of the anterior communicating was also recorded. Results: Out of twenty specimens studied, 8 specimens showed variations in the formative pattern of circle of Willis. Like The basilar artery continued as Left posterior cerebral artery, Right posterior cerebral artery arising was from right internal carotid artery with Bilateral absence of Posterior communicating artery , right posterior cerebral artery was arising from Right internal carotid artery. Bilateral fetal type of Posterior cerebral arteries. A long anterior communicating artery of about one cm (10mm) was also observed in one of the cases. Though variations of the arteries at the base of the brain are common, it is necessary to be aware of all the variations as they may breed problems in the blood flow to the brain and may cause confusions in radiological procedures.
