Computer image analysis as a tool for microbial viability assessement

The 5th ENGII Conference——Application of the computer image analysis for improving microbial viability assessment by plate count and fluorescence microscopy was investigated. Yeast cells were used as a model microorganism. The application of the improved methods for the viability assessment of yeast cells after preservation by freezing and freeze-drying was demonstrated.

Evaluation of Phytochemical Content And Antibacterial Properties of Two Varieties of Kolanut (Cola Nitida L.)

The 5th ENGII Conference——Kola nut is a native stimulant which is commonly chewed in many West African cultures, individually or in a group setting. It is often used ceremonially and to honour guest. Phytochemical analysis and antibacterial screening of red and white Cola nitida (kola nut) extracts were evaluated using qualitative and quantitative method.

Viability and Proteolytic Capacity of Lactobacillus delbrueckii subsp.bulgaricus NCFB 2772 and Lactobacillus rhamnosus GG during Cheese Ripening

The 5th ENGII Conference——In this study, the protective effect on the survival of Lactobacillus rhamnosus GG was determined in a cheese which was inoculated only with this probiotic microorganism, and in another cheese additionally inoculated with Lactobacillus bulgaricus 2772 (exopolysaccharide producer bacteria). The ripen-ing of these cheeses took place for 28 days at two different temperatures (4 and 14℃). The prote-olytic capacity was analyzed by measuring the concentration of free amino groups, through the trinitrobenzenesulfonic acid method (TNBS).

Recent Trends in Wireless Multimedia Sensor Networks(1)

The 5th ENGII Conference——In recent years extensive research has opened challenging issues for wireless multimedia sensor networks (WMSNs) deployment. Among numerous challenges faced while designing architectures and protocols, maintaining connectivity and maximizing the network lifetime stand out as critical considerations. As a fundamental objective, maintaining is a dependable operation of a network. However, the resource constrained nature of sensor nodes and ad hoc network topology, often coupled with an unattended deployment, pose non-conventional challenges and motivate the need of special techniques for dependable design and management of wireless sensor networks. Data gathered from sensor nods in physical proximity tend to exhibit strong correlation.

Scalable trust:based secure WSNs

The 5th ENGII Conference——In this paper, we consider the scalable of wireless sensor networks with trust-based security. In our setting, the nodes have limited capability so that heavy computations are not suitable. So public key cryptographic algorithms are not allowed. We focus on the scalability of the network and proposed new testing algorithms and evaluation algorithms to test new nodes added, which give them reasonable values of trust. Based on these algorithms, we proposed new components for trust management system of wireless sensor networks.

Attention Drawing of Movie Trailers Revealed by Electroencephography Using Sample Entropy

The 6th ENGII Conference——A movie trailer is a common advertising tool in the entertainment industry. Detection of a viewer’s brain responses to a movie trailer can help film producers to tailor a more appealing trailer of a movie. In this study, we acquired electroencephalographic (EEG) signals from subjects when they watched movie trailers (labeled as Movie session), and compared with their resting state session (labeled as Resting session) or when they watch nature scenes (labeled as Nature session). We used Sample Entropy (SampEn) to analyze the EEG signals between different sessions. Results showed that the complexity ratios at Fp1, Fp2 and Fz channels derived from Movie session were significantly lower than that in Resting state or when subjects watched Nature session. Our results suggest that the brain status can affect the complexity of their EEG. Further, the attraction of attention of a movie trailer can be observed from the change of EEG.

Generation of antioxidant mouse models with graded gene expression

The 6th ENGII Conference——Oxidative stress is implicated in pathogenesis of many diseases and antioxidant therapy is a plausible method for treatment of these diseases. The studies will test our hypothesis that the mice that have low antioxidant levels would be vulnerable to the diseases related to reactive oxygen species (ROS) and these mice would benefit greatly from antioxidant intervention. The hypothesis will be strengthened by exogenous lipoic acid (LA) administration. On the other hand, mice with an enhanced antioxidant reservoir are more resistant to ROS and should retard the development of the diseases.
