An adequate blood flow supply is necessary for all organs of the body. Analysis of the blood flow finds its importance in the diagnoses of diseases. There are many techniques for analyzing the blood flow. These techniques are not affordable by the poor people because of their high expense. So we have implemented a technique called Zoom-FFT. This technique is simple and affordable to detect the blood clots and other diseases. Here a specific application will be dealt i.e., ultrasonic blood flow analyzer using ZOOM FFT. The implementation must be achieved with a single VLSI chip in order for the system to be both cost-effective and power efficient and thus widely accepted.

The experimental study has been made to utilize natural agrosilica (agrowaste) as a pozzolana by partial replacement of cement. The agrowastes that are rich in silica namely sugarcane bagasse ash, rice husk ash, wood ash are being taken for the study. The study is done for compressive strength, split tensile strength, flexural stength. Optimum percentage of replacement of different agro waste is determined. Thus utilization of agro waste in concrete and accounts for green concrete.

The increasing competition in the business sector requires that teams that are involved in developing the brands come up with brands that consumers can easily differentiate from those of the competitors to make their brand stand out. Football teams rely on fans for their success, providing income through ticket sales, television viewing from proceeds of advertisement and purchasing team branded products. Yet this area remains unexplored in Kenya hence the researchers desire to assess the influence of brand equity on customer satisfaction of football team among universities female fans in Public Universities in Kenya. The specific objective was to examine the influence of perceived quality of a team jersey on customer satisfaction of a football team among female fans in public universities in Kenya. The Ministry of Sports will recognize how the female fans benefit sports and justify higher budgetary allocations for female league. The research study was anchored on the economic theory of discrimination which stipulates that groups are collectively against each other. In this theory men hold a taste for discrimination meaning that there is a disamenity value to women watching football. Hence female fans feel inferior in stadiums to their male counterparts. The study adopted explanatory research design to determine the influence of brand equity on customer satisfaction of a football team. A target population of 1846 respondent was investigated. A sample of 319 was then used for the study. Stratified and snowball sampling techniques were employed. Semi-structured questionnaire was used as instrument of data collection. Content validity was measured through expert judgment while reliability was measured by use of Cronbach’s Alpha coefficient method at p<0.05. The data obtained was analyzed using descriptive and inferential statistics comprising of chi-statistic, multiple regression analysis and Anova. The first objective sought to examine the influence of perceived quality of a team jersey on customer satisfaction of a football team among female fans in public universities in Kenya. A hypothesis was formulated with the assumption of no significant effect. The result shows that the value of test statistic is 21.339. The p-value of the test statistic is p=0.046 since the p-value is less that the chosen level of significance (0.05) null hypothesis was rejected.

Fish constitutes a very important component in the diets ofboth man and animals as it provides the much needed protein and other nutrients for a healthy living however, it is prone to rapid putrefaction and spoilage. In this study, local spices were applied on hot-smoked African catfish for its preservative tendencies using Response Surface Methodology of Design Expert 6.0.8.Five independent variables consisting of soaking times of 0.0, 7.50, 15.00, 22.50 and 30.0 min; soaking temperatures(30, 35, 40, 45, 50oC); garlic, ginger and turmeric with concentrations of 0.0, 2.50, 5.00, 7.50 and 10.0 g/100ml respectively were investigated. Predictive models for the response variables were developed as a function of process variables. A second-order polynomials obtained to predict the response variables were all significant (p<0.05) with good correlation coefficients (R2) between 0.869 and 0.999 showing that the models can be used to navigate the design space. Selection of the best (optimum) combination of garlic, ginger and turmeric concentrations, extraction temperature and extraction time of 7.29 g/100ml, 7.50 g/100ml, 2.5 g/100ml, 38.65 oC and 7.51 min respectively produced optimized responses in spiced smoked catfish with CP, ash, TP, FRAP, MC, fat and FFA of 65.20%, 8.59%, 2.45 mg/100 g, 20.24 mg/100 g, 2.20%, 11.17% and 0.72% respectively. This successfully established the synergistic effect of local spices on the chemical and antioxidant properties of the hot-smoked catfish

The Internet is a widely used tool known to foster addictive behavior, and Internet addiction threatens to develop into a major public health issue in the near future in a rapidly developing country like India. Internet addiction in adolescence can have a negative impact on identity formation and may negatively affect cognitive functioning, lead to poor academic performance and engagement in risky activities, and inculcate poor dietary habits. Recent reports indicated that some online users were becoming addicted to the Internet in much that same way that others became addicted to drugs or alcohol, which resulted in academic, social, and occupational impairment. The aim of the study is to examine the prevalence of internet addiction among adolescents.For the purpose of the study 272 adolescent’s students (176 male, 96 female) from formal schools and colleges at Chhattisgarh. The sampling was based on random sampling method. The age range of the students is 14yrs-19yrs. The tools, demographic data sheet designed for the purpose of this study and Internet Addiction Test (IAT) by Dr. Kimberly Young to measure the levels of internet addiction were used. The results revealed that prevalence of average internet addiction was 57%, problematic addiction was 41.9% and severe addiction was 0.7%. The gender difference was found on internet addiction that males were more addicted to the internet than female. It was also found that the duration of internet surfing and time spent for internet usage of the students were significant for internet addiction. Based on the results, internet addiction should be considered as a serious problem in adolescents and young adults. So, it is necessary that proper use of internet to be educated to adolescents and young adults to prevent the risk of internet addiction.

The present study aims at examining the influence of receptive (reading three glossed sentences) and productive (completing a cloze task) tasks on retrieving the knowledge of English verb-noun collocations in an Iranian English as a foreign language (EFL) learning context. To do so, ninety four EFL university learners were divided into two experimental (reading and cloze) groups and one control group. To examine the effects of the tasks, the students in all three groups were given receptive and productive collocation pretests aiming at measuring their existing knowledge of collocation and posttests to measure the learners' gained knowledge of collocation after being exposed to the treatments. Two weeks after completing the treatments, the students were given delayed posttests examining the participants’ ability to retrieve the receptive and productive gained of the collocations. The results of Paired Sample t-tests revealed that the tasks were highly effective in helping the students retrieve the already gained knowledge of verb-noun collocations.

Distributed denial-of-service (DDoS) attacks remain a major security problem, the mitigation of which is very hard especially when it comes to highly distributed botnet-based attacks. The early discovery of these attacks, although challenging, is necessary to protect end-users as well as the expensive network infrastructure resources. Here, we address the problem of DDoS attacks and present the theoretical foundation, architecture, and algorithms of FireCol. The core of FireCol is composed of Intrusion Prevention Systems (IPSs) located at the Internet Service Providers (ISPs) level. The IPSs form virtual protection rings around the hosts to defend and collaborate by exchanging selected traffic information. The evaluation of FireCol using extensive simulations and a real dataset is presented, showing FireCol effectiveness and low overhead, as well as its support for incremental deployment in real network.

A field experiment was conducted at Firozabad region of Iran to study the effect of Effective Microorganisms Activate (EMa), EMa levels on growth, yield, Yield Components and Water Usage Efficiency of two Maize cultivars (Ns640 and Back cross 666).
