Ten (10) brands of industrially manufactured Soft Drinks in Nigeria were randomly selected and subjected to bacteriological analysis by the pour plate count method. 1ml of each brand of the soft drinks were dispensed into different sterile Petri dishes while 12mls of molten Nutrient Agar and MacConkey Agar respectively were poured into the petri dishes at about 37oc, thoroughly mixed, allowed to set and incubated aerobically at a temperature of 37oc for 24 hours. The number of colonies was counted for viable cells per ml of the original sample. The colonies isolated from the samples include Ribena: Staph aureus 11(2.6%), E.coli 2(19%), Klebsiella pneumonia 2(3.2%); Pepsi Staph aureus 0(0%), E.coli 0(0%), Klebsiella pneumonia 0(0%). Coke: Staph aureus 0(0%), E. coli 29(27.8%), klebsiella pneumonia 0(0%). Schweppes: Staph aureus 57 (13.4%), E.coli 0(0%), Klebsiella pneumonia (0)0%. Lucozade boost: Staph aureus 3(0.7%), E. coli 0(0%), Klebsiella pneumonia 0(0%), Maltina: Staph aureus 48 (11.3%), E.coli 41(39.4%), klebsiella pneumonia 0(0%). Sprite: Staph aureus 24 (5.6%), E.coli 32(30.7%), Klebsiella pneumonia 0)0%), orange juice: Staph aureus 0(0%), klebsiella pneumonia 0(0%). Malta Guinness: Staph aureus 92 (21.7%), E. coli 0(0%) klebsiella pneumonia 61 (98.8%) Fanta: Staph aureus 189 (44.6%), E.coli 0(0%), klebsiella pneumonia 0(0%). The highest number of colonies was found in fanta while lucozade boast yielded the lowest number of colony, pepsi and orange juice, showed no growth. Staph aureus had the highest prevalence while klebsiella pneumonia yielded the lowest number of organism. It is also recommended that regulatory agencies should ensure strict adherence to established standards, manufacturers should ensure that the soft drinks must be free from contaminants, and workers should regularly be screened.

Country’s development is in the hands of future generation. Obesity is the biggest threat to the children’s health. The hidden risks of fast food such as obesity and food borne illnesses are not a simple complication. The fast food industry is a complicated web of growing problems. This threat is nowadays common among urban areas as they have more exposure to modern life style. The extension of fast food culture and its dreadful consequences even in rural areas is to be prevented

Marketing in today’s world is so difficult for existing players and the new entrants due to the fast growing, changes in the customer preference and tastes, rapid growth of technology, penetration of foreign players in the local market, price sensitiveness of customers and quality consciousness of government for attracting, acquiring, retaining customers in the business. To identify the attitude of the customer in the banking sector, a study has been made in the Tiruchirappalli region among private bank.

DMFC has tremendous potential in serving as a source of clean and renewable energy. Different catalyst combinations are prepared and characterized in DMFC at various operating conditions. The characteristic curves are plotted. Effect of prepared catalyst in DMFC performance is analyzed at load and no load conditions. Demerits of Platinum catalyst is minimized to a great extent by the specially designed catalyst combinations. Based on the DMFC performance, the best catalyst combination (Pt-Ru/C) is identified and analysed in different operating conditions.

The organic nitrates are widely used in the management of coronary artery disease. They are given not only to patients with stable angina pectoris, but also to those with unstable angina, acute myocardial infarction, and heart failure. Although they are effective for the treatment of these disorders, their therapeutic value is compromised by the rapid development of tolerance during sustained therapy. Long-acting nitrates can provide protection against the development of angina for up to 12 hours each day if an appropriate dosing regimen or formulation is used. Regimens with proved effectiveness include intermittent transdermal nitroglycerin, standard-formulation isosorbide mononitrate given eccentrically, and sustained-release isosorbide mononitrate given once daily, but there is some concern that nitrate-free periods may have adverse effects in some patients. Although the mechanism of nitrate tolerance has remained elusive, studies in animals suggest that nitrate therapy causes specific biochemical responses in the vasculature that limit the vasodilator effects of nitrates.

The evolution of web 2.0 has made social media networks more prevalent. Forums, blogs, tweets and posts, have become an important media for internet users to share views. With the evolution of Natural Language Processing (NLP), sentiment analysis is being essentially used as a means to determine the attitude of a person with respect to some topic or the overall contextual polarity from these inputs. The attitude may be his or her judgment or evaluation, effective state mind or the intended emotional communication. As e-commerce is becoming increasingly popular, the number of customer reviews that a product receives grows rapidly, which is being encouraged by the merchants selling the products. For a popular product, the number of reviews can be in hundreds or even thousands. This paper describes the concepts of sentiment analysis from unstructured text, looking at why they are useful and what tools and techniques are available. It also focuses specifically on a novel feature based opinion extraction scheme demonstrated with key open-source tools and applications and the problems associated with opinion detection in social media have also been analyzed.

This paper proposes a the common sharing distributed arithmetic method with less number of flip flops to reduce the power consumption by the circuit. To achieve the lesser number of Flip flops usage the registers used in the circuit to create latency will be replaced by buffers. By using the buffers in the circuit itself can create some latency efficiently than using the more number of flip flops in the circuit.

Occurrences of certain defects are inevitable despite meticulous planning, proper process control, and good documentation during software development. Such defects lead to quality degradation which can be the underlying reason for failure. Conscious efforts are required to control and minimize software engineering defects, but this costs money, time and resources. Predicting defective software module facilitates maintenance and corrective measures. In Software Defect Prediction (SDP), predictive model estimation is based on code attributes to assess software modules containing errors likelihood. This study proposes improved activation function based on cubic spline for Multi-Layer Perceptron Neural Networks (MLPNN) to classify SDP. The proposed method is evaluated using KC1 dataset.

This study has examined the effects of place attachment and its impacts on sustainable development. To perform this, the components of place identity including emotional attachment, place attachment and social bonding which totally constitute theoutput of place attachment, by means ofthe standardized questionnaireconsistingof22questions, measure place attachment in threedomains of(cognitive) the place identity, (affective) emotional attachment and (behavioral) place attachment and social bonding. The relationship between the results of independent variable of place attachment on the sustainable development is visiblein terms of descriptive and inferential. Byelicitingthe responses' results of the present situation of the site on theattachment variables'meanit has been shown low attachment, also, ithas been observed that attachment rates in women aremore than men. However, the result of proposal has shown that the mean of attachment variables represents high attachment, also it has been observed that attachmen trates in women aremore than men. The abover esults confirm the relationship between place attachment and sustainable development.

Menopause is associated with a large number of symptoms ranging from physical to psychological. These symptoms may unfavorably affect oral health and treatment needs requiring dentists to be aware of the symptoms and health care needs of peri-menopausal/menopausal/postmenopausal women. After menopause, women become more susceptible to periodontal disease. Various internets based popular search engines were used to explore related data from literature, which includes PubMed, PubMed Central, Cochrane, Google, Medknow, Ebsco, Science Direct, and IndMed. Upon compilation of relevant data, it was observed that periodontal health is most severely affected (up to 60%) followed by dry mouth (25%) and burning mouth (glossodynia; 15%) which, in turn, may increase the occurrence of oral mucosal and dental diseases, such as candidiasis. We believe the problem is due in large part to estrogen deficiency with resulting bone loss and inflammatory processes. Osteoporosis and periodontal disease are best diagnosed early so that treatment can be started sooner and fractures and tooth loss can be prevented.
