Influence of Some Local Spices on Chemical and Antioxidant properties of Hot-Smoked African Catfish (Clariasgariepinus)
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

Internet Addiction among Adolescents
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.

Introducing reading and cloze tasks as panaceas for Iranian EFL learners’ loss of memory: a case of collocation retrieval
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.

Intrusion Prevention System (IPS) countering DDOS attack in internetworks
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.

Investigation of different methods of biological Ema (effective microorganism active) use on quality and quantity production and water use efficiency in two cultivars of corn
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). The experiment consisted of 10 treatments which were the combinations between two factors: two cultivars and five EMa levels.Ns640 cultivar significantly exceeded Back cross 666 in more growth characters, yield and its components. The result indicates that EMa increases growth and grain yield and water usage efficiency of Maize.

Mechanism of tooth eruption & its clinical significance - A systematic review of literature
Tooth eruption is an important, complex and highly regulated process. It involves signaling from a large number of genes and molecules. This review outlines the possible mechanism of tooth eruption right from its development in the bony crypt to its eruption till the occlusal level. Active tooth eruption starts from intra-osseous stage when there is formation of eruption pathway. Colony stimulating factor (CSF-I)and monocyte chemotactic protein (MCP) plays an important role in osteo- clastogenesis. Inhibition of osteoproteigrin (OPG) transcription and enhancement of receptor activator of nuclear factor kappa B ligand (RANKL) is important . Paracrine signaling by parathyroid hormone-related protein(PTHrP) and Interleukin-1?produced in stellate reticulum may also play a role in regulating eruption. Wnt/?-catenin signaling plays a critical role in bone formation and regeneration and thus tooth eruption. Correct understanding of this important event is needed to diagnose and treat disorders of tooth eruption.
