This research describes a mammographic lesions using wavelet based active contour model. The sensitivity of the breast cancer detection was analyzed by mammography. Wavelet based decomposition techniques are used and tested for decomposing the noise present in the mammographic lesions. Gabor filtering method is used to reduce the unwanted noise obtained in the mammographic lesions by automated segmentation. The experimental results are tested with the MATLAB and proved reliable and cost effective.

This study aims to investigate the similarities and differences of some anger metaphors in English and Mongolian. The study is done within the cognitive semantics framework along with the principle of CMT (Layoff and Johnson 1980, 1987; Kövecses 1986, 1988, 2000) framework in English and Mongolian. To compare the results of the study in both languages, the author selected the three parameters proposed by Barcelona (2001) and Kövecses (2001) including (1) the existence and nonexistence of language-specific mappings, (2) degrees of linguistic elaboration, (3) degrees of linguistic conventionalization. The source domains chosen for the analysis are rooted in the most fundamental human experiences in the sedentary and nomadic cultures.This current study highlights the importance of culture in understanding the relationship between metaphor, culture and cognition, and it provides comparative generalizations for the four basic emotion concept of anger and gives the fundamental explanations in English and Mongolian. This systematic comparative analysis of emotion metaphors in English and Mongolian contributes importantly to the major claims of the Contemporary Metaphor Theory, which states that metaphors are grounded on both universal embodiment and social-cultural experiences. Even though English and Mongolian belong to very different language families representing totally different sedentary and nomadic cultures, they share some universal conceptual metaphors for particular emotions with each other.

Schistosomiasis mansoni is among the neglected diseases that occur in Brazil, being endemic in 76 countries and territories spread across Africa, Asia and the Americas. The granulomatous process in schistosomiasis is dependent on CD4 + and requires recruitment and accumulation of inflammatory cells at the site of eggs deposition. Schistosomal fibrosis is the result of a granulomatous reaction developed in response to antigens released by eggs of Schistosoma mansoni that are retained in the portal veins of smaller caliber. Manipulation of the interaction between B7 antigen molecules presenting cells (APC) and T cell receptors CD28/CTLA4 modulate and, in some circumstances, even block the immunological response in vivo. Therefore, the objectives of this study were: a) to evaluate treatment with monoclonal mice anti-CD28 (PV-1 cell line hybridoma), b) to evaluate the contribution of the synthesis and release of IL-4 and IL-5 when correlated with IgE and IgG1 levels and granuloma and fibrosis formation during schistosomiasis. Our results suggest that treatment with anti-CD28, on day 64 post-infection, favored a decrease in IL-4 and IL-5 production and decreased levels of IgG1 and IgE expression, as well as a reduction in the collagen deposition resulting from fibrosis.

In last few decades computer scientist has started taking interest in the quantum computing in order to resolve some of the problems in the recognizable classical computers. Relevant efforts have been put into the practice for two instructions: the basic assumptions behind the quantum mechanics has a residential affect, on the other hand a series of project has been used to show the series of implementation of all these algorithms. This will move the quantum from area of assumptions’ to the actual level. The relationship between these two areas is generally the feasible algorithms for quantum, which settle down their model of quantum circuit.

One of the main concerns of economists and economic policymakers is predicting future values of economic variables. One of these variables is stock index that, according to the importance of financial markets in economic development and also attractiveness of investing in this market could have many costumers. Therefore, in this study, with the daily data of years 2006 to 2012 the total index of Tehran Stock Exchange (TIPEX) using artificial neural networks (ANN), auto regressive moving average (ARIMA), and models accuracy comparison have been predicted. Results suggest that, there is no significant difference between the accuracy of neural networks models and moving auto regressive average.

The article analyses the concept of motivation and features some facts on the importance of differentiation between the intrinsic-extrinsic constructs and integrative-instrumental orientation to motivation, as well as the necessity to study students’ actual motivational background to learning English. The article describes a recent study of motivational basis in Psychology students in terms of learning English. The research aims to find out and to assess the presence of a certain motivational type and orientation. The author examines and interprets the results of a written questionnaire concerning definite orientations to motivation in Psychology students of Cherkasy National University.

A simple, precise and accurate kinetic spectrophotometric method has been developed for determination of tranexamic acid. The method was based on a kinetic investigation of the coupling reaction between tranexamic acid and ascorbic acid after heating to form a purple-pink colored complex. The reaction was followed up spectrophotometrically by measuring the increase in absorbance at 530nm & 390nm as a function of time. The initial rate, rate constant, fixed time and fixed absorption time methods were adopted for constructing the calibration curves and examined for their suitability for the assay of tranexamic acid in pure and capsules forms.

Deforestation and forest degradation are still occurring at an alarming rate, and are contributing significantly to the current loss of biodiversity. Every year, about 13 million hectares of forest are converted to various uses. Many ecologists attest that sylviculture is one of the remedies to this problem. In this paper, we evaluate the impact of silvicultural techniques on the carbon sequestration potential of Millettia laurentii plantations. A carbon stock estimation study was conducted in 2016 in three silvicultural plots installed in 1940 following the Layon, Blanc etoc and Martineau techniques. Diameter at breast height of 359 M. laurentii individuals and wood density were used in an allometric equation to estimate biomass and sequestered carbon. In the Layonnage plot, biomass and carbon stored were 914.39 t/ha and 457.19 t/ha respectively; 695.47t/ha and 347.74t/ha in the Blanc Etoc plot; 767.67 t/ha and 383.8 t/ha in the Martineau plot. After 76 years in plantation, the Layon technique proved to be more favorable to biomass production and carbon stock by M. laurentii. 

Testing the presence of sugar in urine will serve as an additional diagnostic tool to verify and correlate with the glucose level in plasma. The earliest test was done by using benedict’s reagent and the reports were given ranging from nil to several positives depending upon colour changes. Dry Chemistry is now emerging as the latest technology for detecting sugar in urine, both qualitative and quantitative and some companies have developed instruments to read the intensity of colour obtained using reflectance principle and to report the urine sugar results quantitatively. Several commercial brand of test strips are available for urine sugar testing and many studies have been done in evaluating their merits and demeirts. This research paper is an attempt to find out the correlation between plasma and urine glucose both estimated quantitatively. Good correlation was found between plasma and urine glucose (P<0.00001). While dialab reagents and DIRUI CS 1300B analyser were used to measure plasma glucose, DIRURI H 100 reflectance analyser and multistix marketed by the same company was used to measure urine glucose. This research work suggests that every lab using quantitative urine glucose measurement based on dry chemistry test strips should evaluate its performance.

Empirical studies on the short run and long run effects of the exchange rates on trade balance are classified in two groups. First group have used the overall level of foreign trade data between one country and the world, and second one (including this study and recent studies) have employed bilateral trade data between a country and its major trading partners. The present paper by using Auto Regressive Distribution Lags (ARDL) and annually data during time period 1979-2006 has analyzed the presence of J curve between Iran and selected European trading partners including France, Germany and Switzerland. The results obtained shows that the bilateral J curve hypothesis is confirmed in the short run but there is no evidence to support for the hypothesis in the long run. So, based on the results, the hypothesis is not completely confirmed. It’s mentionable that regarding to and tests, all coefficients are stable.
