This study examines a survey and analysis of the wrong use of the past perfect tenses by students in essay writing. The survey became necessary because of the in-depth deficiency students exhibited in essay writing in West African Senior Certificate Examination (WASSCE) and National Examination Council (NECO). The respondents of the study consisted of final year senior secondary student for the WASSCE and NECO classes and respondents from High Impact Capacity Teacher Building Workshop. They were required to write an essay or composition titled ‘My Best Teacher’ on page I of High Impact Capacity Teacher Building Workshop. It was discovered that there were some similarities in the type of errors, especially in the area of past perfect tenses in the second composition: ‘My First Day in the School (page 48-50). (Taken from Countdown for WASSCE/SSCE, NECO, JME English Language (Ogunsanwo et al 2005).

Fourth-Generation (4G) wireless networks will be heterogeneous, integrating different networks to provide continuous access for mobile users with multi mode access capability. The Fourth Generation communications systems is all about a global wireless communications system and defines a cost effective, simple, operable and personalized according to the users’ needs concept. The vertical handoff requirements are potential of the network, network cost, handoff latency, network conditions, power consumption and user’s preference. These must be considered during vertical handoff. In this research paper a new vertical handoff decision based on ARM & AI Techniques is designed. A refined, intelligent Associative Rule Mining (ARM) and Artificial Intelligence (AI) based technique is used to execute the vertical handoff intelligent mechanism in fourth generation wireless networks to produce an effective service which reduces the handoff delay and complexity.

Web-based decision support systems are used to model data and make adequate decisions based upon it. They address the needs of managers in solving structured and semi-structured problems. They have provided assistance to human discrimination to put right people in right places. This research paper focuses on Academic Course Scheduling Decision Support System, which provides a reliable tool that can be used to improve decision making process in academic course scheduling. Due to the dearth of adequate classrooms in most academic institutions, and pressure on the available ones, it becomes more and more difficult for school management to battle with the problem. This paper gives a model for appropriate scheduling of courses to classrooms, as well as determining courses priorities. To facilitate good implementation of this work, the researchers painstakingly took out time to collect enough data from the case study (Adekunle Ajasin University, Akungba-Akoko, Ondo State, Nigeria) as well as materials and journals from various authors/sites. The application was developed using a scripting language, PHP, and MySQL database as backend to effectively achieve the aims of this project.

The ameliorating effect of Emblica officinalis was evaluated against changes in sperm and hormone of mice. The animals received aqueous preparation of Endosulfan (Pesticide) once daily for 35 days at the dose of 3 mg/kg body wt by oral gavage method and observed deleterious effect such as of reduction in the number of sperm count and motility. Declination in the level of Testosterone were observed which signify the testicular dysfunctions and finally causes infertility. To ameliorate the deleterious effect made by endosulfan, Emblica officinalis was administered to mice @ 100 mg/kg body wt & 150 mg/kg body wt The earlier study have demonstrated potent anti-microbial, antioxidant, adaptogenic, hepatoprotective, anti-tumor and anti-ulcerogenic activities in the fruits of Emblica officinalis. Emblica officinalis treatment mitigate the fluctuation in sperm count and sperm motility as well as elevated the level of testosterone which was depressed by pesticide treatment.

There has been a wide variety of research going on in the field of privacy preservation in data mining. Most of the methods are implemented for static data. But the world is filled with dynamic data which grows rapidly than what we expect. No technique is better than the other ones with respect to all criteria. This paper focus on a methodology that is well suited for incremental data that preserves its privacy while also performing an efficient mining .the method does not require the entire data to be processed again for the insertion of new data. The method uses data summarization technique which is used for both incremental data and providing privacy for such data. We develop the algorithm for making the environment flexible and cost effective.

Ten new heterocyclic moiety containing Schiff bases have been synthesized by the condensation of 4,5-diazafluoren-9-one with substituted amines by using SnCl₂ as a catalyst under solvent free condition. The Schiff bases were obtained in good yields and easy to isolate. Some synthesized products were characterized by IR, NMR and MASS and also tested for antibacterial activities by disc diffusion method.

Automated extraction of popular news from the freely accessible news corpora is becoming important in today’s internet world. Because of the availability of large volumes of news wire sources, it is hectic for the human beings to search and decide whether it is popular or not. This necessitates a tool which should extract hot news in a period of time. Term weighting is a useful technique which extracts salient features from the text documents. Though, there exist different tools based on different term weighting algorithms, these are inaccurate in the extraction of hot news. In this paper, a new feature extraction algorithm for long running events based on frequency, position, scattering and topicality is proposed. Experimentation has been done on different retrospective news wire sources. Experimental results demonstrate that the proposed algorithm is suitable for extracting hot news.

This study aimed at discovering if young and adult learners of English language who had been taught Interchange Series would be similarly affected in terms of cultural orientations. To unravel whether learning a foreign language presupposes cultural adaptability, the study also sought if the two groups would perform differently on their achievement tests. To conduct the study, a questionnaire was constructed based on the cultural components discovered in the Interchange Series by Zarei and Khalessi (2010). The two groups of L2 learners who had already completed the three volume Interchange Series in a language institute in Isfahan, Iran, were asked to list the cultural issues from the most preferred to the least. At the end of their program they had sat for their final exams, which were analyzed later. The results indicated that while the adult learners’ preferences were domestically oriented, the young learners of English gave precedence to the cultural issues with western flavor. As regards their course scores, the two groups were not meaningfully different. It can be gathered that textbooks can make young learners conceptualize the world as portrayed therein. The results rejected the idea of acculturation adaptability as a pre-requisite to learning a foreign language.

This study deals with the process of local assimilation of consonants in Kurdish. It is conducted within the theoretical framework of Optimality Theory(OT). The study hypothesizes that among the constraints of local assimilation , markedness is more dominant than faithfulness. It is also claimed that local assimilation can be found within a word and not necessarily between word boundaries. The paper is divided into three main sections; the first section addresses the main concepts and trends concerned with optimality theory. The second section deals with assimilation, its main concepts and categories. The third section shows the cases of local assimilation of consonants in Kurdish within the framework of OT. The sample of the study are all taken from (Sorani Kurdish- the semi standard dialect in Kurdish Language) from written and oral sources.
