Experimental Study on the Performance of Reinforced Sand Beds Under Repeated Loads in Presence of Water

The performance and behavior of reinforced soil structure, both in the field and the laboratory are well documented. In the field situation, when the reinforced sand beds are used as a construction tool or as a ground improvement method, it is often the situation that they are subjected to the effect of water. In this study series of repeated load tests were conducted on mild steel square footing of 100mm size resting on a sand bed placed in a 500mm-dia, 390mm deep mild steel tank. Reinforcement location and spacing were selected based on optimization of previous research results. The sand beds were inundated to different levels viz full and partial. The results of the experiments demonstrated the impact of pressure of water on the performance of reinforced earth when subjected to repeated loading. The reinforced sand beds are very efficient under the repeated loads and the presence of water table has a considerable influence on their performance. The cyclic resistance ratio of the reinforced sand bed increases and the settlement ratio reduces considerably, when reinforcements are introduced in them

Aetiopathology of ulcers of oral cavity and oropharynx: a cross sectional study

Background: Oral ulcers are common diseases for which patient seeks medical advice. Till date the clinical profile to diagnose the oral ulcers, management and risk of malignancy is not well established. Hence, the study has been taken up to investigate the aetiopathology of ulcers of oral cavity and oropharynx.Methods: 60 cases of ulcers of oral cavity and oropharynx were included in the study. The aetiopathology of ulcers of oral cavity and oropharynx were investigated on the basis of age, sex, duration, etiological factors, symptom Index, socioeconomic status and anatomical distribution. Values are expressed as percentages. Results: The highest incidence was found in low socioeconomic status. The lesions studied in this study were 50% of Non Specific ulcers [Short term (3 wks) 10-33%], 15% of Aphthous ulcers, 8.3% of Traumatic Ulcers, 6.5% of Malignant ulcers, 6.5% of Dental ulcers, 3.2% of HIV infection & AIDS, 3.2% of ulcer due to T.B and 6.5% of ulcers. The majority of the cases were between the age 21-30 years constituting 35% followed by 11-12 years constituting 26.6%.d 62% of the short term ulcers, Female 38%.Conclusions: Low socioeconomic status, lack of education, bad oral hygiene, bad habits cultivated in early childhood is predisposing factors. Hence early diagnosis and prompt treatment is advised in all cases of ulcers.

A study on the clinical profile of ulcers and membranous lesions of oral cavity and oropharynx

Background: An ulcer is a discontinuity of an epithelial surface. Many a times, patients with oral ulcers are treated sympathetically without even coming to a definitive conclusion of their problem. Oral ulcers are common diseases for which patient seeks medical advice. Till date the clinical profile to diagnose the oral ulcers, membranous lesions of oral cavity and oropharynx is not well established. Hence, the study has been taken up to investigate the aetiopathology of ulcers of oral cavity and oropharynx. Methods: 60 cases of ulcers of oral cavity and oropharynx were included in the study. The aetiopathology of ulcers of oral cavity and oropharynx were investigated on the basis of age, sex, duration, etiological factors, symptom Index, socioeconomic status and anatomical distribution. Values are expressed as percentages. Results: The highest incidence was found to be in low socioeconomic group, where there is lack of education, improper food habits, cultivation of bad habits in early childhood and negligence of the disease are the predisposing factors in most of the malignancies. The highest incidence was found in low socioeconomic status. The lesions studied in this study were 50% of non-specific ulcers (Short term (3 wks) 10-33%), 15% of Aphthous ulcers, 8.3% of Traumatic Ulcers, 6.5% of Malignant ulcers, 6.5% of Dental ulcers, 3.2% of HIV infection & AIDS, 3.2% of ulcer due to T.B. and 6.5% of ulcers. The majority of the cases were between the age 21-30 yrs constituting 35% followed by 11-12 years constituting 26.6%.d 62% of the short term ulcers, Female 38%. Conclusions: Low socioeconomic status, lack of education, bad oral hygiene, bad habits cultivated in early childhood is predisposing factors. Hence early diagnosis and prompt treatment is advised in all cases of ulcers.

An Improved Integrated Hash and Attributed based Encryption Model on High Dimensional Data in Cloud Environment

Cloud computing is a distributed architecture where user can store their private, public or any application software components on it. Many cloud based privacy protection solutions have been implemented, however most of them only focus on limited data resources and storage format. Data confidentiality and inefficient data access methods are the major issues which block the cloud users to store their high dimensional data. With more and more cloud based applications are being available and stored on various cloud servers, a novel multi-user based privacy protection mechanism need to design and develop to improve the privacy protection on high dimensional data. In this paper, a novel integrity algorithm with attribute based encryption model was implemented to ensure confidentiality for high dimensional data security on cloud storage. The main objective of this model is to store, transmit and retrieve the high dimensional cloud data with low computational time and high security. Experimental results show that the proposed model has high data scalability, less computational time and low memory usage compared to traditional cloud based privacy protection models

Proportion, Risk Factors and the Impact of Dysmenorrhea among Girls

Background: Dysmenorrhea is the leading cause of recurrent short-term school absence in adolescent girls and a common problem in women of reproductive age. There are many factors related to this disorder which include a younger age, low body mass index (BMI), smoking, early menarche, and prolonged menstrual flow. Objectives: (1) To find the proportion of dysmenorrhea among girls of a nursing college; (2) To find out the risk factors and impact of dysmenorrhea.Materials and Methods: A cross-sectional study was conducted from November 2011 to April 2012 at Nursing College, VIMS, Bellary, Karnataka. Data were collected by a pre-tested and pre-designed semi-structured pro forma. The study was performed on a total of 196 students who agreed to participate and present at the time of study. Analysis was done by using Epi-info version 3.4.3.Results: The average age of the study group was 19.3+1.8 years (range 17–30). Proportion of dysmenorrhea was found to be 77% and was significantly higher in females with positive family history of dysmenorrhea when compared to the others (P<0.05), who had early age of menarche, irregular cycle, increased amount of flow, gynecological problems and lack exercise had high rate of dysmenorrhea compared to others but statistically it was not significant. In this study, because of dysmenorrhea 20.5% had class absenteeism, 23.2% college absenteeism, 44.4% had poor concentration, 31.8% were depressed, 53% were irritable and 2.6% had suicidal tendencies.Conclusion and Recommendation: There was a high proportion of dysmenorrhea and also girls were very much worried about it. There is a need to educate them about causes, treatment and also to cope with stress at the time of menstrual cycle
