This paper proposes a novel technique, based on Canonical correlation analysis, and the Chi-square test is employed to test the significance of the correlation coefficients. If it is significant, then it is concluded that the input query and target images are same or similar; otherwise, it is inferred that the two images are significantly different. In order to experiment the proposed canonical correlation method, a database is designed and constructed with the help of different types of images and their feature vectors. The Fβ-measure is applied to evaluate the performance of the proposed method. The obtained results expose that the proposed technique yields better results than the existing.

The dynamic linkage between exchange rate and stock returns has been subjected to considerable attention from researchers worldwide. However the relationship of exchange rate with returns of different industrial sectors has not been much examined. In this reference the present paper investigates the causal relationship of Indian sector based daily returns with Indian rupee-US Dollar Exchange Rates for a period from January, 2007 to March, 2015. The study observed absence of normal distribution, unit root as well as co-integration in the data. Correlation between returns and Exchange Rates was found to be negative. Granger Causality test highlighted bidirectional causal relationship between the exchange rate and stock return for each sector except for Pharmaceutical and Media. Pharmaceutical index reported unidirectional relation running from exchange rate to the industry. In case of Media sector return and exchange rates a unidirectional relation running from the former towards the latter has been observed.

This paper studies the vehicle spare parts production problem to obtain the optimum production rate under fuzzy capital budget. We applied the integer goal programming technique to determine the best compromise solution. There are two goals in our case study. These goals are minimization of the uncertain capital budget and maximization of the uncertain expected profits. The case study is a factory which produces different types of vehicle heat exchangers. The results indicate that the problem solution depends on the membership function and the α- cut. The optimum quantities of heat exchangers’ production are found to be biased to the lower limit of production.

The rate of caesarean section is constantly increasing beyond the recommended level of 5-15% by world Health Organization. Caesarean section is usually performed to ensure safety of the mother and child under conditions of obstetric risks. This medical intervention is more or less justified under certain circumstances such as breech presentation, dystocia, previous caesarean section and suspected fetal compromise. Caesarean section rate varies in different places depending on type of care giver and type of facility. In the last decade, the rate has increased almost double. In developing countries like India too many women are undergoing caesarean section. This trend is rising in urban as well as in rural population of India. In 2010, the incidence was around 8.5% but a phenomenal increase of 40 % was seen in Kerala and Tamil Nadu .It is found that the low threshold for caesarean is becoming common in rural India as well.

Primary English language teaching curriculum in Bangladesh underpins Communicative Language Teaching (CLT) approach. It focuses on developing communicative competence among EFL (English as a Foreign Language) learners in Bangladesh. NCTB (National Curriculum Textbook Board) is responsible for developing English textbooks for primary level students with a view to promoting communicative competence among the learners. However, it is observed that principles of CLT are not reflected in classroom teaching and testing. This study aims at exploring the existing scenario of our English classroom practice. By adopting a mixed method approach we tried to investigate into the issue. The analysis of the collected data reveals that there exists no uniformity between curriculum statement and classroom teaching and testing method. At the end of the study, we have suggested some recommendations to address the mismatch between Primary English teaching curriculum and its implementation.

This study aimed to reveal the role and altered immunohistochemical expression of α- catenin in oral squamous cell carcinoma progression in its three histopathological differentiations. Immunohistochemical method was used to stain 81 biopsy taken from 81 patients and 15 control sample from normal oral mucosa. α-catenin was detected with homogenous strong staining in 56.6%, 40%, 15% of well, moderately, poorly differentiated squamous cell carcinomas, respectively with p<0.05. the heterogenous slight staining appeared in 40%, 52%, 61.5% respectively with p<0.05. the loss of α-catenin is observed in oral squamous cell carcinoma progression. The appearance of α-catenin oral SCC and invasive carcinomas might suggest its role in tumor progression by influencing on APC to control β-catenin dissolution and transcriptional suppression of Wnt pathway in this type of carcinogenesis.

SPIDER is the name of the first Exchange Traded Fund (ETF), introduced in 1993 in USA. After twenty years of its inception, Bangladesh is going to introduce this investment instrument at DSE soon. This article gives the readers a comprehensive idea about the origin, its differences with other related investment funds, its creation and redemption process, its usage to its investors, benefits, related risk factors, its evaluation factors and costs to the investors. ETF is a hybrid attractive investment instrument and possesses qualities of both the mutual fund and common stock. It avoids disadvantages such as lack of transparency, agency conflicts etc. of closed end mutual funds and takes the benefit of the flexibility of common stocks. For Bangladesh, where the structure of Stock Market lacks accountability, this sort of investment instrument which has transparency will bring confidence among the customers. The neighboring countries where it has been introduced has been successful. More can be stated regarding ETF in perspective of Bangladesh after its official introduction at DSE.

The radiogenic heat produced from radioactive elements has been investigated in some parts of Niger Delta sedimentary basin. The heat production was computed from gamma ray logs for three oil producing wells. The major lithology observed in the gamma ray log is alternation of sand and shale. The computed value ranges between0.35 to 2.0μWm-3 for well 1, 0.34 to 1.78μWm-3 for well 2 and 0.24 to 2.0μWm-3 for well 3. The average radiogenic heat production ranges between 0.3 to 1.93μWm-3. It was observed that the heat production within the sand lithology ranges from 0.24 to 0.7μWm-3.Whilethe computed value for the shale lithology ranges from 0.8 to 2.0 μWm-3. The high radiogenic heat production in shale was as a result of high concentration of radioactive elements. The sandstone zone was deficient of radioactive elements and this resulted in the low value. The plot of depth against radiogenic heat production was scattered and it also showed an increase with depth. The increase was due to high shale lithology at greater depth of the Agbada Formation and the shale in the Akata Formation. A linear relationship was established for the radiogenic heat production and the product of gamma ray and density logs for the study Area. The relationship can be used if gamma ray spectral logs are not available.

The International Atlas of Clouds was produced as a result of long observations and it lists 10 cloud species, 14 cloud types, 9 cloud subtypes, 9 accessory clouds and their possible varieties. The Cloud Atlas contains the characteristic features of clouds, their height measured from the Earth’s surface, among others. The measured altitude values result from a great many instrumental measurements, so for the purposes of describing the height of a selected cloud species, the tables – due to the alterations of the volumes determining the atmosphere – contain not only one specific altitude value, but a series of values covering a wide range.
