 Abstract

Background: Breathing problemsis one of the most common causes of malocclusion specially in Children. Many of these children are misdiagnose. It is important for the entire health care community (including general and pediatric dentists) to screen and diagnose for breathing problem in childrenand adults between 5 to 16 years of age. If mouth breathing is treated early, its negative effect on facial and dental development and the medical and social problems associated with it can be reduced. Method: Breathing problem can cause malocclusion between children to early adult, so the sample was collected between the ages of 5 to 16 years of 20 patients, from Department of dentistry, National Medical College, Birganj Nepal. Result: Untreated 20 patients, sample were collected between the ages of 5 to 16 years of 20 patients with a mean age of 11.64 years. The sample was divided into 2 groups with 10 subjects in each, group 1 had history of no breathing problem had Dental Class I malocclusions and normal growth patterns; group 2, had nasal obstruction and Dental Class II malocclusions and vertical growth patterns as evaluated (molar relationship) on dental casts and lateral cephalogram . Conclusion: Above study shown that breathing problem can causes malocclusion like Dental class II malocclusion,vertical growth pattern with long, narrow faces, narrow mouths, high palatal vaults, gummy smiles, and many other unattractive facial features.

 Abstract

The concept of potential is not very clear among the undergraduates they often make vague mistakes in using the concept of potential in electrostatic problems. One of the things that are taken as granted is that the potential of Earth is zero. Actually there is nothing as zero potential. Electric potential is rightly viewed when it is compared with height as in gravitational field. Just as for defining height we need a reference point from where we start measuring height for defining electric potential we need a reference point where the potential is zero. So why do we take the potential of Earth as zero? So, here in this paper I have addressed this question from a mathematical point of view. Where i have taken two spheres one charged (which is the smaller sphere) and one uncharged (which is the bigger one). Then I have assumed the bigger sphere as the earth where the radius of the earth is very large as compared to the radius of the sphere. And then came to a conclusion that indeed the potential of the earth is zero.

A significant number of contemporary researches on business ethics and its importance can be found in most acclaimed academic articles. However, there is yet a research that specifically focuses on how ethical business culture affects the ethical behaviours of businessmen. Workplace ethics are a dynamic set of values that change with people and their definition of a workplace. For some, it's a physical office they are going to each day, while others, their headquarters. It doesn't matter whether you work from home or commute to work every day, workplace ethic is required to build a successful career. Organizations are known to embrace ethical practices and behaviours to increase productivity and uphold integrity while setting a penalty for workers who default workplace ethics. Hence, this paper will conceptually investigate ethical business culture and the way this ethical context negatively affects ethical misconduct of businessmen within the workplace. This study aims to point the essentiality of facilitating ethical business culture in business organizations. It is necessary to establish a proper and clear understanding about how ethical business culture helps enhance ethical work behaviours. Such understanding should be beneficial for business leaders also as organizational development practitioners in promoting business ethics by creating an ethically-sound culture in business.

 Abstract

All the samples of the three systems selected for the present study are expected to show the variying catalytic activities. It is known to us that the catalytic activities of the samples would be mainly the functional properties of the surfaces. Thus in the specific condition in which the samples are prepared, the excess surface oxygen (E.S.O) must play an important role in controlling and characterising the surface heterogeneity of the catalyst, a vital factor contributing towards the catalytic reactivity. Sahay etal have observed that acidity, excess surface oxygen and activity for hydrogen peroxide decomposition are directly proportional to each other. Madhok 2 carried out an extensive investigation on oriental adsorption of normal aliphatic alcohols on pervoskite type oxides. He reperted that the change in E.S.O with the decomposition temperature of the catalyst should be related with the catalytic activity.

 Abstract

Concrete technology has made significant advances in recent years which results in economical improvement of the strength of concrete. This economical development depends upon the intelligent use of the locally available materials. The cheapest substitute for natural sand is quarry dust .Quarry dust, a by-product from the crushing process during quarrying activities is one of the materials being studied . The residue quarry fines less than 4.75mm obtained from the crushed quarry rock often termed Quarry dust or Quarry stone dust (QSD) and replacing the natural fine aggregate (NFA) by proportions 0 and 100%.The results indicated that the incorporation of quarry dust into the conventional Concrete mix as partial replacement material to natural sand resulted in higher compressive strength and optimization of sand replacement is 40%.

The purpose of morality in Buddhism is to create an environment in which everybody attain nirvana, "when a man gives , his merit will increase, no enmity can grow in the self-restrained. The skilled shun evil; they attain nirvana. By ending greed and hatred and delusion." Here the Buddha follows the path of deontological ethics in daily life.

In this paper, a brief review of Artificial Neural Network or ANN in the field of Artificial Intelligence is represented. As artificial neural structure is inspired from the biological neuron that is responsible for transformation of signals in human brain, is explained in this paper. ANN is the network models that make machines more intelligent to act more likely or equal to human beings. The most common choice of leading ANN is the decision-making quality. They are adaptive learning models that work on prior data sets. Biological neuron model plays a vital role in the working guidance of ANNs. The approach of these networks is heading more day by day.

 Abstract

Introduction: Maxillary premolars have a complex and variable anatomy and are the only tooth that shows eight configurations of the Vertucci classification. As they correspond to the adjacent maxillary molar in morphology, maxillary second premolars with 3 roots are called �small molars or radiculous�. Endodontic success in teeth with a number of canals above that normally found requires a correct diagnosis and careful clinical radiographic inspection. Case description: This case report aims to describe the endodontic management of a maxillary second premolar with three roots and three canals. Canals were enlarged up to ProTaper F2 size by instrumenting 1 mm beyond the apical constriction. Irrigation was done with 3% sodium hypochlorite and 17% EDTA gel was used as a lubricant and obturation was done with guttapercha points and AH plus sealer using single cone technique Conclusion: This case report presents the management of a patient who presented with the uncommon anatomy of three root?canaled maxillary second premolar. One of the cause for failure in endodontic treatment is incomplete obturation and unnoticed canals. Clinical thoroughness and early identification of aberrant tooth morphology assist in refraining possible mishaps.

 Abstract

Genetic algorithms (GAs) are multi-dimensional and stochastic search methods, involving complex interactions among their parameters. Researchers have been trying to understand the mechanics of GA parameter interactions by using various techniques. It still remains an open question for practitioners as to what values of GA parameters (such as population size, choice of GA operators, operator probabilities, and others) to use in an arbitrary problem. Genetic algorithm (GA) parameters are explored to minimize the time needed to find a solution. The basic GA code stays the same throughout the entire system. Variable parameters include mutation rate, crossover rate, crossover operator, number of generations, population size, etc. When an optimization problem is encoded using genetic algorithms, one must address issues of population size, crossover and mutation operators and probabilities, stopping criteria, selection operator and pressure, and fitness function to be used in order to solve the problem. This paper tests a relationship between (1) size of the initial population, (2) mutation probability, and (3) number of generations in runs of Genetic Algorithm for solving the TSP.TSP is an NP-hard problem, so using the Genetic Algorithm we can find a solution in a reasonable amount of time. In this thesis we describe the results of the solution for the Traveling salesman problem (TSP) for Kosovo municipalities, using the genetic algorithm, with different settings for the parameters of the Genetic Algorithm.

 Abstract

Forensic video/Image analysis techniques are used many times to perform visual data analysis. Video/Image forensics analysis is considered to be important to show that images and videos which are to be used as potential evidence in court of law are verifiably true / authentic. The popularity of digital devices such as smart mobile devices and also due to increasing number of low cost surveillance systems, several forms of visual data are widely being used in digital forensic investigation. Digital videos are used most of the times as key evidence sources in evidence identification, analysis, presentation, and report. A Deep Learning based forensic video/image analysis framework can be developed that employs an efficient video/image processing techniques using deep learning, such as object detection framework YOLO V3, CNN based summarization of videos, enhancing algorithm for the low quality of video footage analysis which consists of adaptive video enhancement algorithm based on Contrast Adaptive Histogram Equalization (CLAHE) technique, Contrast Exposure Fusion Algorithm, Dynamic Histogram Equalization (DHE) which are termed to be useful in order to improve the quality of visual data for the use of digital forensic identification & investigation. The technique of Video/Image tampering detection using state-of-art techniques and textual enhancement are also termed to be important in order to assist in truthful analysis of visual data evidence. The framework would deploy recent techniques and algorithms which will assist examiner to perform visual analysis of evidence data.
