The soil microbiota is vulnerable to burning; however, it shows some resilience. No indices have yet been developed assess fire damage related biota. We evaluated the biological recorded by a Biolog EcoPlate System in Mediterranean ecosystem. experiment was carried out an outdoor forest lysimeter facility (MedForECOtron), where we simulated burns with different burn severities. Burning increase...

Streptococcus iniae was isolated from red-tail black shark(RTB shark) Epalzeorhynchos bicolor, and rainbow shark, E. erythrurus (fam: Cyprinidae), obtained from a local freshwater ornamental fish farm in Hillsborough county (FL). Darkening of the skin and lethargy were the first signs observed in infected sharks. Hemorrhages were observed on the ventral side of the body, on the head, and at the...

seemed to have in the past towards the logit transformation have now been withdrawn but the use of logits is not described in this book. The later chapters of the book provide both a framework of theory based on maximum likelihood estimation and a discussion of more specialized practical problems such as the study of the joint action of drugs. These later sections are not easy to read but are w...

The major clinical problem for patients with cystic fibrosis (CF) is progressive loss of pulmonary function, usually due to chronic bacterial infections. A patient with CF and a lung transplant was severely infected with a previously unidentified gram-negative bacterium. We isolated this organism (strain DS15158) from the patient and characterized it by phylogenetic analysis of the small-subuni...

The sensible use of forest resources and the sound management forests have become increasingly important throughout years. In keeping with trend, a composite forestry operation model has emerged. Traditional Chinese culture are particularly intertwined in China. Thus, forest–medicine compound is recommended. majority research on compounds focused how to grow more effective medicinal plants, ign...

This paper summarizes work on an approach that combines feature selection and data classiication using Genetic Algorithms. First, it describes our use of Genetic Algorithms combined with a K-nearest neighbor algorithm to optimize classiication by searching for an optimal feature weight-ing, essentially warping the feature space to coalesce individuals within groups and to separate groups from o...

Controlled fermentation processes have high potential for improving coffee quality. The effect of temperature on beverage quality was investigated with cultivated at elevations between 1166 and 1928 m. A completely randomized design carried out five elevation ranges 200 m intervals in farms per range, two temperatures (15 °C 30 °C), which were maintained a temperature-controlled bioreactor. Eac...

a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...

The Biolog technique was introduced into ecological studies to estimate metabolic potential of microbial communities. while utilizing carbon substrates (95 or 31x3, depending on the plate type), microbes reduce a colourless dye to violet formazan. The colour is measured spectrophotometrically. This is a rapid and quite convenient method but it has many drawbacks – for example, only microbes tha...
