Investigations on the associative interrelationships between microorganisms have engaged increasing attention in recent years. As is well known, these relationships play an important role in nature and also in many branches of industrial.microbiology. In view of the great significance of these associative phenomena in biology, and especially in microbiological ecology, this is undoubtedly a fie...

We propose a segmentation method based on Polya's (1931) urn model for contagious phenomena. A preliminary segmentation yields the initial composition of an urn representing the pixel. The resulting urns are then subjected to a modified urn sampling scheme mimicking the development of an infection to yield a segmentation of the image into homogeneous regions. This process is implemented using c...

This volume presents the state-of-the-art of omics in soil science, a field that is advancing rapidly on many fronts. The various omics approaches hold much promise but also await further refinement before they are ready for widespread adaptation. One way to judge their readiness is to compare them to methods that have become standards for soil microbiology research. Methods become standards be...

Modeling of complex phenomena such as the mind presents tremendous computational complexity challenges. The Neural Modeling (NMF) Fields theory and Phenomena Dynamic Logic (PDL) address these challenges in a non-traditional way. The main idea behind its success is matching the levels of uncertainty of the problem/model and the levels of uncertainty of the evaluation criterion used to identify t...

The paper investigates the special clustering phenomena that one can observe in systems of nonlinear oscillators that are coupled via a shared flow of primary resources (or a common power supply). This type of coupling, which appears to be quite frequent in nature, implies that one can no longer separate the inherent dynamics of the individual oscillator from the properties of the coupling netw...

An outbreak of Legionnaires’ disease with 334 confirmed cases was identified on 7 November 2014 in Vila Franca de Xira, Portugal and declared controlled by 21 November. Epidemiological, environmental and microbiological analysis identified industrial wet cooling systems to be the probable source of infection. Preliminary results from sequence-based typing of clinical specimens and environmental...

Following the discovery of discoloration on some pages of the Atlantic Codex (AC) of Leonardo da Vinci kept in the Biblioteca Ambrosiana in Milan, some investigations have been carried out to verify the presence of microorganisms, such as bacteria and fungi. To verify the presence of microorganisms a noninvasive method of sampling has been used that was efficient and allowed us to highlight the...

djendjen river is one of the largest rivers in the region of jijel (algeria). human activities such as urban discharges, industrial, agricultural, and livestock have significant effects on the quality of water. the present study attempts to evaluate the quality of water along the banks of the djendjen river at different sampling sites, using physico-chemical and bacteriological methods. the col...

Microorganisms have a significant influence on human activities and health, and consequently, there is high demand to develop automated, sensitive, and rapid methods for their detection. These methods might be applicable for clinical, industrial, and environmental applications. Although different techniques have been suggested and employed for the detection of microorganisms, and the majority o...

an agar well diffusion bioassay method for determination of clarithromycin in human plasma, using micrococcus luteus atcc 9341 as the assay organism, was compared with a selective high-performance liquid chromatographic (hplc) method with uv detection. spiked plasma was used to prepare standard and control samples for both methods. the results of the bioassay analyses with spiked plasma samples...
