Persistent left superior vena cava is rare but an important congenital vascular anomaly. When superior cardinal vein caudal to innominate vein fails to regresses PLSVC occurs. It is observed in isolation but associated with other cardiovascular abnormalities including atrial septal defect, biscuspid aortic valve, and coarctation of aorta, coronary sinus ostial atresia, and cortriatratium. The PLSVC can render access to right slide of heart challenging via the left subclavian approach, which is utilized using pacemaker and Swiz-Ganz catheters. Incidental notation of dilated coronary sinus on echocardiography raises the suspicion of PLSVC. The diagnosis is confirmed by saline contrast echocardiography.

Interrupted aortic arch a rare abnormality, is the discontinuity of the ascending and descending aorta. There are three types which are classified based on the area of interruptions. They are Type-A, Type-B and Type-C. In the Type-A form, the interruptions occurs distal to the origin of the left subclavian artery. Type-B interrupted left aortic arch is characterized by the interruption that occurs between the left subclavian artery and left common carotid artery. Type-C variants are due to the interruption or discontinuity between the innominate artery and the left common carotid artery.

A slimy bloom of the marine Haptophyta, Phaeocystis globosa was newly recorded in the Gulf of Mannar, near Manapad coast during the summer season (May-June 2012). The cells were generally in colonial form, embedded with in a gelatinous matrix. The intensity of the bloom was as high 2,96,040 colonies/l. The photosynthetic pigment chlorophyll ‘a’ ratio varied from 138±145 ?g/l. The physical and chemical parameters including salinity, temperature, pH, nutrients and dissolved oxygen were evaluated along with Phaeocystis data. In this study, nitrite, nitrate, inorganic phosphate, ammonia was also determined as following ranges 0.454±0.544, 1.16±3.42, 6.70±13.70, and 0.13±0.36 and 5.8±23.30 ?g/l respectively. The previous report revealed that the occurrence of Phaeocystis globosa recorded in the mid-region of Arabian Sea. Therefore, the present study was proved that this is the first report on the occurrence of Phaeocystis bloom from the Gulf of Mannar waters and concluded that this species might be introduced by ballast discharge and adapted to new environments due to anthropoid influence. This newly recorded species is highly deserved for further study.

The incidence, effect, and causal organism of fungal leaf spot diseases of orange tree (Citrus spp.) in Southeastern Nigeria were investigated. Healthy and diseased samples of orange leaves were obtained from Aba, Amagunze, Awka, Nkpor , and Onitsha all in Southeastern Nigeria. Sabouraud dextrose agar (SDA) was used for isolation of fungi. Ten trees with disease symptoms were sampled at each location using visual assessment method and their percentage frequency calculated. The occurrence of fungal leaf spot was least at Nkpor (30%) and highest at Aba (43%). The fungi identified were Aspergillus niger, Fusarium solani, F. oxysporium, Botryodiplodia theobromae, and Geotrichium spp. The F. solani occurred at highest percentage of 37.5% incidence while the lowest was B. theobromae at 6.25%. The pathogenicity test revealed that the major cause fungal leaf spot disease of orange was B. theobromae, Fusarium solani, and F. oxysporium. Although, leaf spot disease is a minor economic problem that reduces crop yield, a number of control measures need to be adopted.

Visual cryptography (VC) is a technique for protecting the secret image which encodes the picture into many shares and allots them to different members. At the point when all shares are adjusted and stacked together, they uncover the secrete image. In k out of n (k, n) VC plot, the secret image is shared into n shares to such an extent that when k or more members by storing up their transparencies by methods for an overhead projector to uncovers the secret image. This paper proposed a spic and span of basic and strong (k, n) visual cryptography method which is utilized to successfully imparting the secret image to most extreme classification. In share creation process, determined new condition for arbitrary grids and after that XOR activities are performed to produce the 'n' transparencies. It is conceivable to decipher the secret image outwardly by superimposing a k subset of transparencies. All things considered no mystery information can be procured from the superposition of an unlawful subset. Trials, measurable and security evaluations are completed on the offers to approve the quality of the proposed plot by methods for a succession of examinations, for example, visual testing, encryption quality testing, security investigation and diverse assaults. The proposed (k, n) VC plot offers a reliable insurance for conveying pictures over people in general channels.

In this article, a report of a study to investigate pertinent citations in the introduction sections of empirical article published in Turkish Journal of Chemistry is presented. It is attempt to proceed with the validation that majority of citation made in the introduction sections of scientific articles are impertinent to the study. In this study, an empirical investigation of pertinence of citations made in Turkish Journal of Chemistry is presented. In this particular study, citations made in the introduction sections in issues published from 1997 to 2004 were analyzed. An empirical scientific article was randomly selected from every issue published, and the pertinence of selected article was determined. Overall, the result showed that less than 20% of the citations were pertinent to the study. This result suggests that over 80% of citations made in the introduction sections may not be applicable in the computation of effective impact of publications.

It is obvious that learning new vocabularies in the process of acquiring a second language has always been significant. First and best medium in every language is vocabulary. No connection is possible without knowing the words. Using words means connection. Without using vocabularies and knowing their meanings, speaking is worthless and meaningless. Acquisition of new words is of various procedures. Some learn new words through speaking and some learn by reading. In second language teaching and learning vocabulary through reading, there are two instructional techniques: incidental learning and intentional learning. This case study explores the role of reading in S2 vocabulary acquisition, and the effect of different vocabulary instructional techniques on the vocabulary learning of Iranian advanced EFL students who learn English in English institutes. The results of the study produce the following findings: 1) Both instructional treatments result in significant gains in learners` receptive vocabulary knowledge, but the combination of the incidental and intentional learning instruction leads to greater vocabulary gains and better retention. 2) Students` vocabulary size plays a decisive role in acquiring the productive aspect of the vocabulary knowledge.

Present medical science very much depends on the medical images and medical imaging technology like MRI, CT, US, etc. Doctors are using these medical images for the anatomical structure study and for the treatment planning. But generally medical images are complex and noisy. This paper discuss about the segmentation and pre-processing which reduce the complexity of medical image analysis and eliminate noise and unwanted region without any loss of important information in the image. Region growing segmentation is considered for the segmentation and compared the performance with pre-processing.

The purpose of this study was to investigate the effect of Student Councils Involvement in Decision Making and Its Effect on Students’ Discipline in Nandi North Sub-County. This study was hinged on the Participative Leadership Theory (Yukl, 1994) which posits that involvement in decision making improves the understanding of the issues in schools. The study adopted mixed research methodology and targeted 43 school principals, 43 deputy principals and 559 student Council leaders. The sample size for students in this study was determined using Krejcie and Morgan formula. The respondents were selected through the use of stratified and simple random sampling techniques. Questionnaires, interviews and document analysis were used for collecting data relevant to this study. Validity was determined through expert opinion while reliability was determined through piloting and use of croncbach alpha. The analysis involved descriptive and inferential statistics namely; Pearson rank correlation. Data was presented in form of tables, figures and charts. Further, most (55.6%) of the student council leaders reported that students in their schools participated in BOM meetings. Similarly, majority of the student council leaders believed that student involvement in decision making through council members have helped solve indiscipline cases in school. The study findings indicated that there is a strong and significant relationship student council involvement in decision making (r = .723) and school discipline in secondary schools in Nandi North Sub-County. This implies that students should be involved in development and implementation of school rules and regulations in order to enhance student discipline. The study will be useful to the Ministry of Education to have information on the operation and effectiveness of students’ councils since it is still a new policy. It also will yield data and information that was useful to policy planners and decision makers to follow up on policy implementation and evaluation on its role in improving the welfare of students.

It is fact that an Islamic society has different religious teachings and different values for its members as compared to non Islamic society. Therefore, in an Islamic society, cultural, social and moral values should be different; and consumer crimes should be also different. In practice, it is seen that in the era of globalization, mostly developing societies whether these are Islamic or non Islamic societies, all have similar consumer crimes. This shows that whether the Islamic societies are not acting upon Islamic teachings, or members of Islamic society have same worldly objectives like others. Or, these members are also giving preference to this mortal life over hereafter world. Therefore, in this article an overview about the consumer crimes of modern and globalized era is presented. In these crimes, some are committed by consumers while some others are committed by sellers and manufacturers. The purpose of both parties is to deceive the other which is not true, morally, socially and religiously also.
