CMOS Monolithic Active Pixel Sensors (MAPS) form a promising sensor technology for the micro vertex detector (MVD) of the Compressed Baryonic Matter (CBM) experiment. The technology allows for building very thin (∼ 50 μm) detectors with a spatial resolution of few μm and a satisfactory time resolution of 10 μs. It is expected that within one run of CBM, the MVD will be exposed to a radiation do...

The rates of parasitism of Theridion evexum by the parasitoid wasp Zatypota petronae, and Allocyclosa bifurca by Polysphincta gutfreundi, were followed for two years. Parasitism of T. evexum was very low (mean 1.39 +/- 1.8%), and restricted to nearly seven months of the year. Parasitism of A. bifurca was higher (mean 7.8 +/- 7.6%), and did not show a seasonal pattern. Reproduction of the host s...

The fact that living organisms exhibit certain electrical phenomena has long been known, but understanding of their significance and meaning is limited. The attempt to explain the several aspects of biological activity which can be recorded by electrical devices has, in general, rested on the assumption that the underlying phenomena are chemical and that the electrical records represent by-prod...

The effect of commercially available chestnut and mimosa tannins in vitro (experiment 1) or in vivo (experiment 2) on the growth or recovery of Escherichia coli O157:H7 or generic fecal E. coli was evaluated. In experiment 1, the mean growth rate of E. coli O157:H7, determined via the measurement of optical density at 600 nm during anaerobic culture in tryptic soy broth at 37 degrees C, was red...

The use of vegetable tannins is a bio-based alternative to chrome tanning. most used extracts are Mimosa and Quebracho. To improve the sustainability tanning process, chemically unmodified pine bark could be as natural source tannins. present study was aimed evaluate environmental impact powder obtain leather through life cycle assessment. Specifically, evaluation performed for both: i) tannin ...

Mature motor cells of Mimosa pudica that exhibit large and rapid turgor variations in response to external stimuli are characterized by two distinct types of vacuoles, one containing large amounts of tannins (tannin vacuole) and one without tannins (colloidal or aqueous vacuole). In these highly specialized cells we measured the abundance of two tonoplast proteins, a putative water-channel prot...

Mimosa pudica is the most abundant and problematic invasive species in tropical pastures. This study investigates the effects of two cattle grazing systems, long-term moderate grazing (LTG, 2.7 animal unit/ha/yr for 33 years) and short-term heavy grazing (STG, 5 animal unit/ha/yr for 2 years) compared with ungrazed exclosure pasture on the invasion of M. pudica and its relationship with herbage...

The classical approach to model collective biological cell movement is through coupled nonlinear reaction-diffusion equations for biological cells and diffusive chemicals that interact with the biological cells. This approach takes into account the diffusion of cells, proliferation, death of cells, and chemotaxis. Whereas the classical approach has many advantages, it fails to consider many fac...
