Negative differential resistance in nanoscale transport in the Coulomb blockade

Motivated by recent experiments, we have studied transport behavior of coupled quantum dot systems in the Coulomb blockade regime using the master (rate) equation approach. We explore how electron-electron interactions in a donor-acceptor system, resembling weakly coupled quantum dots with varying charging energy, can modify the systems response to an external bias, taking it from normal Coulomb blockade behavior to negative differential resistance (NDR) in the curent-voltage characteristics

SUB-TRIDENT FORM USING FUZZY AGGREGATION

This Paper deals with the solution to find the Optimal Path and the Optimal Solution with the help of Fuzzy Aggregation Operations such as Arithmetic Mean and Geometric Mean and by using Trapezoidal Fuzzy Numbers through Pascal’s Triangle Graded Mean Approach. Here the results are obtained as Fuzzy Sub-Triangular Form and this form in turn converted to Sub-Triangular Form. The Minimum value of Sub-Trident Form gives the Shortest Path and the Optimum Solution is obtained by giving a suitable numerical example

Living Environs and Nutritional Status of Children from an Urban Indian Slum: An Analysis of Associative Factors

Growing urbanization gives rise to slums, which are densely populated peri-urban areas housing underprivileged populations. The nutritional status of children in slum areas can be compromised due to poor living environs despite availability of many urban health care facilities. The present cross- sectional study was undertaken to determine the nutritional status of children residing in slum and analyze the various associative factors. The study area was Ghousianagar, a slum in city of Mysore from South India. A sample of 676 children (2-11 years of age, males, 310 and females, 366) from two schools was chosen for detailed anthropometry. Data were also collected on living conditions, economic and literacy levels of parents and nutritional status of mothers (n=200) through standard techniques. The results revealed that the living conditions of children were highly unhygienic. Only in 36% of families both parents were literate. Children from all age groups exhibited different degrees of malnutrition which worsened with increasing age. Only 8% of children were normal and the rest suffered with different degrees of undernutrition. Stunting and wasting were significantly influenced by age and gender of children. Under associative factors studied, weight for age of children was significantly associated with economic status of family and maternal BMI. Weight for height was associated with economic status, family size and maternal BMI. Height for age exhibited marginal association with family size. It can be said that adverse living environment and limited resources influenced the nutritional status of children adversely

Factors influencing progression rate in higher education in Oman-data engineering and statistical approach

The paper highlights key issues in student progression in a tertiary level educational system. The colleges operate under the ministry of higher education, ministry of men power. Private universities are affiliated with the external universities from the developed world. Students come from various backgrounds and allocation of students to the education system depends on the performance of the student in the school. The good students get placed in state universities and colleges and those who could not get in the state universities get placed in private universities and colleges. Progression rates in all the type of system is a challenge. We have addressed a way to overcome this problem in this paper. An attempt is made to analyze the factors influencing progression rate in higher education system via data engineering and statistical approach

A Review of Vrushya Dravyas of Guduchyadi Varga of Bhavaprakasha Nighantu

Bhavaprakasha Nighantu, an important lexicon of Ayurveda consists of 23 Vargas where Guduchyadi Varga is one among them which consists of 190 drugs. Among them 28 drugs are attributed to Vrushya property. As Infertility has emerged as one of the most common health issues that many young couples are facing, there is a great demand for the treatment of infertility. While, the herbal therapies are better positioned to offer more holistic approaches to improve reproductive health. So here an attempt is made to screen the Vrushya Dravyas mentioned in Guduchyadi Varga of  Bhavaprakasha Nighantu with their Rasa, Guna, Veerya, Vipaka
