Experimental study on characteristics of bacterial concrete

Concrete is a building material and is widely used in all types of construction works. As we know the concrete is good in compression and week in tension due to microcrack occurs when the load applied on it. Due to these micro-cracks, the concrete loses its strength and water enters through these cracks which causes corrosion to steel. This initiates corrosion makes the whole structure vulnerable and leads to the failure of the structure. Thus, to overcome this problem a technique of adding bacteria into the concrete in order to enhance its properties like compressive strength. The Bacteria may be of liquid or powder form. Together it is called bacterial concrete, in this concrete, the bacteria (Bacillus subtillis) and calcite react with water forms a by-product called calcium carbonate (limestone), which fills the crack and makes the structure sound as it was earlier. This process is called microbiologically induced calcite precipitation. The tests on materials were conducted for the best results and the tests are specific gravity, consistency, Impact Value Test, Shape Test, Sieve Analysis, PH Value (Bacteria), Bacteria Count, etc. The different percentages of bacteria we used in order to know which percentage gives maximum strength. The percentages were made with reference to the amount of cement added into the concrete, the percentages by weight of cement we tried are 1.68%, 2.52%,3.17%,10%,15%, and 20%. And we found 15% of bacterial concrete gave the highest compressive strength in 3 and 7 days test, the result of all tests are given in compressive strength table 2.

Case Study

Accelerating sales for Citrix Education Services using Logistic Regression

This paper aims to establish an efficient model for predicting company sales by leveraging logistic regression's strengths. A real dataset of Citrix used to figure out a significant variable affecting sales acceleration and to find an appropriate metric to measure unstructured information. To build an efficient model, we used two statistical methods; logistic regression and linear discriminant analysis. The classification accuracy of the models compared using Fisher Analysis, ROC curves, and confusion matrix. In regression analysis, it is evident that response and predictors some times may suffer from correlation issues. By definition, Multicollinearity is that two or more predictors are correlated; if this happens, the coefficients' standard error will increase. Increased standard errors mean that the coefficients for some or all independent variables may be significantly different from 0. In other words, Multicollinearity makes some variables statistically insignificant by overinflating the standard errors when they should be significant. In this paper, we concentrate on logistic regression analysis, linear discriminant analysis, Multicollinearity, fisher analysis, and consequences and effects on the reliability of the regression model

Evaluation of crop depredation by Asian Elephant (Elephas maximus) in Badrama Wildlife Sanctuary, Odisha, India

We investigated the human-elephant conflict in eight different ranges in Badrama Wildlife Sanctuary under Bamra (Wildlife) Division, Odisha, India. Elephants were responsible for human casualty, large-scale crop, and property damage; which caused serious human-elephant conflicts in the region were assessed. During 2011-12 – 2015-16, a total of 03 nos. of human killing and 380 human injury cases caused by elephants were recorded. Damage to agricultural crops by elephant was of varying extents i.e. 212.89 acres. As a result, people have developed an antagonistic attitude towards the elephant which adversely affects conservation efforts.

Autism Action Plan of Canada and Northern Ireland – A comparative review

Autism Spectrum Disorder refers to a range of conditions characterised by some degree of impaired social behaviour, communication and language, and a narrow range of interests and activities that are both unique to the individual and carried out in repetition. This paper reviews the Autism Action Plan of two countries, Canada and Northern Ireland and to find out the similarities and differences in their Action Plan and to throw light on their vision, personnel involved (actors) and the policy process. To do this, the health policy triangle has been chosen as a tool to compare and analyse these policies.

Soil Based, Aeroponic and Hydroponic Systems in Space with Microgravity and Hypogravity Conditions

Colonizing space in the future is a widely discussed topic in this generation, and sustaining it requires a strong agricultural system in the hypogravity and microgravity conditions. Potential agricultural systems have been considered to be put into action since Tsiolkovsky’s works in the early 20th Century. Some of these systems include soil based hydraulics and bioregenerative systems, hydroponic and aeroponic systems which are suitable means to support plants in lower gravity conditions. Testing and data collection on soils and other controls have been done for each method by NASA, Kyushu University etc; and it has been evaluated along with results broadly in terms of input and output factors. The input includes conditions such as water (or medium such as soil), nutrient control, atmospheric control, temperature, humidity and output refers to the yield received. The Controlled Ecological Life Support Systems (CELSS) Program at NASA’s Kennedy Space Centre did hydroponic testing that focused on controlled environment production of wheat, soybean, potato, lettuce, sweet potato etc. Further experiments of Silverstone in Biosphere 2 tested the growth of crops in a Martian-like environment that could fulfill the calorie requirement of a four person crew. At Kyushu University, aeroponic nutrient delivery is tested in a microgravity plant growth unit containing radish seeds. The effect of gravity has also been brought about in each method where soil based agriculture loses points due to the toxic gas emissions and suffocation of roots. Even in the comparison of efficiency between aeroponic and hydroponic systems, aeroponic systems are more suitable than soil based space agriculture. A relative weighted comparison between hydroponics and aeroponics reveals that aeroponics is a slightly more efficient system due to higher nutrient control, less space consumption, high nutrient intake, low water requirement, less nutrient wastage, fast growth and germination rate, fewer chances of disease transmission and better utilization of water supply.

Effectiveness of mHealth app on self –management of ascites in terms of knowledge and attitude of chronic liver disease patients

Among all the chronic diseases, Liver Diseases was ranked as the fifth most common cause of death (National Statistics of UK, 2010). The presence of Ascites is a sign of poor prognosis in patients with Chronic Liver Diseases. So, the aim of the present study was to provide an emphasize on Self-Management of Ascites for patients who are living with Chronic Liver Diseases. For this purpose Quantitative approach with Two groups, Pretest-Posttest designs were adopted and a study conducted in Hepatology OPD, ILBS. A total of 60 patients were enrolled based on sampling criteria and consent has been taken. The data was collected by assessing Knowledge and Attitude with Structured Knowledge Questionnaire and Likert Attitude Scale, respectively. These scales were highly reliable and valid. On the same day of assessment of the Experiment group, the mHealth app was introduced and given to the subjects. MS Excel and SPSS 22.0 were used for analysis. The data obtained were analyzed using Descriptive (Mean, Percentage, and chi-square) and Inferential statistics (Paired t-test, Independent t-test, Karl Pearson’s correlation, and Krushkal Wallis test). The study results showed that the majority of patients in both the Experiment and Comparison group were upper-middle-class, male, aged between 47-60 years, married, and residing in urban areas. Independent t-test was computed which showed a significant (p= 0.04) difference between the post-test Knowledge score of Experiment and Comparison group. In the Experiment group, a statistically significant positive correlation (r=0.37, p=0.04) was found between Posttest Knowledge and Posttest Attitude score. Based on the findings of the study, it is concluded that mHealth app was effective in Self –Management of Ascites in terms of Knowledge of CLD Patients.
