Modeling of biomass and stored carbon in a seasonal semidecidual forest in Brazil.

This study estimated biomass and carbon from components, future carbon values ​​and to obtain economic productive value of carbon fixation of a Seasonal Semideciduous Forest. Biomass and carbon were estimated using adjusted equations and selected using regression statistics. The prognosis of the diametric distribution was performed using the movement ratio method.

Holistic tool for ecosystem services and disservices assessment in the urban forests of the Real Bosco di Capodimonte, Naples.

A tool for urban forest Ecosystem services (ES) and disservices (ED) assessment has been developed to visualize (i) overall ES and ED value, (ii) ES-ED trade-off and (iii) explore principal influences in ES and ED provision. The Real Bosco di Capodimonte (RBC) (Naples, Southern Italy) has been chosen as a case study. ES and ED linked to urban forest plant cover were: biodiversity, carbon storage, gross and net carbon sequestration, lessen runoff, oxygen production, air pollution removal, UV effects reduction, pollen-related allergenicity risk, and volatile organic compounds (VOCs) emissions.

Possible involvement of the lysine epsilon-aminotransferase gene (lat) in the expression of the genes encoding ACV synthetase (pcbAB) and isopenicillin N synthase (pcbC) in Streptomyces clavuligerus.

Streptomyces clavuligerus produces the beta-lactam antibiotics penicillin N, O-carbamoyldeacetylcephalosporin C and cephamycin C. We characterized a wild-type DNA region which restores antibiotic formation to a mutant strain named NP1, previously shown to exhibit depressed activities for two early enzymes of cephalosporin synthesis, delta-(L-alpha-aminoadipyl)-L-cysteinyl-D-valine synthetase (ACVS) and isopenicillin N synthase (IPNS). L-Lysine epsilon-aminotransferase (LAT) assays and alpha-AAA feeding experiments suggested that strain NP1 is a lat mutant.

[Obtaining condensed milk from a mixture of hydrosoluble extract of soybean powder and cow's milk].

Three formulations of mix concentrated milk with hydrosolubles extract of soybean powder and cow's milk were prepared. The products were condensed up to 31% and 33.65% of solids in a vacuum evaporator at temperature of 45 degrees and 58 degrees C with a vacuum pressure of 540 mmHg.

[Obtaining macaroni-type spaghetti from a mixture of wheat flour and corn flour].

Pasta products were formulated using 10, 20, 30, 40 and 50% substitution of wheat flour with pre-gelatinized corn flour. Products were submitted to evaluation tests by comparing their main characteristics with those of the pattern, such as humidity, cooking time, water absorption, solubility in cooking water, texture, color, appearance and yield. The products obtained were economically available with good acceptability in relation to color, appearance and other characteristics evaluated.
