Olive (Olea europaea), whose importance is mainly due to nutritional and health features, one of the most economically significant oil-producing trees in Mediterranean region. Unfortunately, increasing market demand towards virgin olive oil could often result its adulteration with less expensive oils, which a serious problem for public quality control evaluators oil. Therefore, avoid frauds, cultivar identification authentication have become major issue producers consumers chain. Presently,...
Biomedical relation classification has been significantly improved by the application of advanced machine learning techniques on raw texts scholarly publications. Despite this improvement, reliance large chunks text makes these algorithms suffer in terms generalization, precision, and reliability. The use distinctive characteristics bibliographic metadata can prove effective achieving better performance for challenging task. In research paper, we introduce an approach biomedical using...
The genetic diversity of 16 Tunisian olive cultivars (Olea europaea L.) known origin sampled from different areas the country was assessed using markers (6 SSR and 5 SNP markers).Three dendrograms based on cultivar genotypes generated by SSR, both revealed three clusters which were consistent with varieties classification according to phenotypic characteristics, but not correlated geographic origin.Also, we compared results obtained those agro-morphological chemicals data bioinformatic...
We summarize here the Implicit statistical inference approach as an alternative to Bayesian networks and we give effective iterative algorithm analogous Expectation Maximization infer signal transduction network when set of data is incomplete. proved convergence our that called apply it simulated for a simplified pathway EGFR protein.
Breast cancer is the leading cause of cancer-related death for women in Tunisia and prognosis its metastasis remains a major problem oncologists despite advances treatment. In this work we use Bayesian networks to develop decision support system that based on modeling relationships between key signaling proteins clinical pathological characteristics breast tumors patients. Motivated by lack prior information parameters problem, Implicit inference structure parameter learning. A dataset 84...
A multiple linear regression analyses were performed to screen for the significant factors simultaneously influencing production of deltaendotoxin, proteolytic activities and spore formation by a Bacillus thuringiensis kurstaki strain. Investigated included: pH medium, available oxygen inoculum size. It was observed that availability most setting on both deltaendotoxins spores counts, followed initial medium On other hand, found be parameter activity, size dissolved oxygen. Our results...
BACKGROUND: In Tunisia, prickly pear fruit grow spontaneously; it is consumed as fresh fruit, juice or jam. When the used for production, seeds are discarded and go to waste. Our study aimed extract biomolecules from by producing value-added products fruits. RESULTS: An amylase Opuntia ficus-indica was extracted purified homogeneity. increase in specific activity of 113-fold observed. The apparent molecular mass enzyme 64 kDa. optimum pH temperature were 5 60 °C, respectively. Under these...
Bacillus thuringiensis (Bt) is a Gram-positive bacterium. The entomopathogenic activity of Bt related to the existence crystal consisting protoxins, also called delta-endotoxins. In order optimize and explain production delta-endotoxins kurstaki , we studied seven medium components: soybean meal, starch, KH 2 PO 4 K HPO FeSO MnSO MgSO their relationships with concentration using an experimental design (Plackett—Burman design) Bayesian networks modelling. effects ingredients culture on were...
Application of magnetic treatment on water and plants has already been shown considerable.A static 3300 Gauss strength was conducted for 1 hour fresh non-sterilized milk some chemical parameters microbial effect were followed through the time.The results showed that preserved pH acidity milk, however it reduced its conductivity in addition, microbiological analyzes have field reduces total number germs about 25%.
