The brazilian food industry (iba): profile and technological dynamics.

This article seeks to identify the main factors behind the Brazilian Food Industries (IBA) innovation process. Initially, we tried to identify which sub-sectors within the food and beverage sector are more innovative than the others, and the role of the different explanatory factors, including competitive strategy that sustain these companies in the national market. In microeconomic incentives to innovate, our results show that there is a limitation of the food industries to innovate in relation to the other processing industries in Brazil, especially in micro and small companies.

Evaluation of hematological variables according to haplotypes in patients with users and nonusers of hydroxyurea in the sickle cell anemia

Clinical and prognostic profile of patient with sickle cell disease may vary according to their type of haplotype and fetal hemoglobin level. Objective: Relate hematological variables to the haplotypes of patients with sickle cell anemia and whether or not they use hydroxyurea. Material and methods: Cross-sectional study of patients with sickle cell anemia users and non-users of hydroxyurea. The hematological analyzes were submitted to laboratory tests as erythrogram and reticulocyte count. The dosage of HbF was obtained by means of High-performance liquid chromatography.

Dna origami and bionanotechnology: an efficacious tool for modern therapeutics and drug delivery

DNA has long been studied because of its irrefutable significance and interaction in all the essential biomechanisms. With the help of Bionanotechnology bottom-up approach, complex 2D and 3D DNA structures can be constructed as DNA origami by using short staple strands. DNA is biocompatible to different materials or particles such as drugs, antibiotics, inorganic molecules, metal particles and small molecules that can be attached precisely at nanometer scale with the DNA origami structures to generate nanodevices and nanomedicine.

Lipid degradation of corn preserved in oxygen depleted minienvironment

The Corn of 13 % moisture content was preserved in air oxygen depleted minienvironment, with oxygen concentration of 15%, 10%, 5% and <2%.The control sample was preserved innatural atmosphere at 20.9 % oxygen concentration. The main nutrient content of maize, such as starch, protein and lipid, were analyzed periodically at 0, 3, 6, 9 and 12 months during the preservation. The result on degradation of starch and protein has been represented previously. This article introduces the research results on the lipid degradation.

Organoleptic properties of developed multigrain flour mix - a functional food

Background: Functional foods are foods that provide additional physiological or health promoting benefits beyond the functions of nutrients contained in foods4. Functional food is a balanced formulated product created to deliver all the nutrients in per ordained proportions. Objectives: to develop multigrain flour blends using very strong functional ingredients and to assess its desirable rate of supplementation in common breakfast recipe i.e. chapatti.

Fire in forest reserve in the caraça sanctuary: the threat to the cultural and natural heritage in minas Gerais, Brazil

This paper presents the eminent threat that a forest fire represents for cultural and natural heritage in the State of Minas Gerais, Brazil, in particular the case of a fire which started on September 24th, 2017, in the forest reserve in the Caraça Sanctuary, an important site not only for its natural richness, characterized by a rich biodiversity, but also by the existence of the architectural complex of the Sanctuary, of great cultural value for the country, made up of buildings that house the old school building, a church and the old seminary.

Transparent concrete as a green material for bulding construction

With the economic process and science-technology development, a lot of and a lot of large-scale engineering structures. Whereas the economicprocess may be a reasonably in depth growth: high input, high consumption and high pollution, for that the energy saving technology is low, particularly in developing countries. The brightness of indoor setting is entirely maintained by artificial lighting, that has consumed an oversized variety of resources.

Design of a circular fractal antenna for satellites applications

Communication systems demand satellite services due its global coverage and capacity to stand all-time communications. Since newer applications need high data rates, higher frequencies are often chosen while considering financial costs. In particular, recent papers show the usage for K and Ka bands. In order to fulfill these requirements, this work shows a modified circular patch antenna with fractal technology applied, which guarantees multiband operation and size reduction – an effect desired to satellite communication.

A numerical study for evolution of the real time for pure gauge theory in quantum mechanics (gluons without quarks) with group su (2)

In this paper, we take the effective Hamiltonian operator until the sixth degree [3] and we apply the perturbation theory (that depends on creation operator 〖D ̂^+〗_i^a and annihilation operatorD ̂_i^a) on remaining homogenous modes after quantization of the inhomogenous modes and we have concluded the time evolution for the average ensemble of global square operator (the color magnetic energy B ̂_i^a B ̂_i^a) analytically, and we calculated this time evolution with MATLAB software, we found that life glasma (gluons) of rank 10-29sec According to coupling constant values.

Application of a new approach in an analytical model to simulate the dispersion of a radioactive pollutant

The contribution of this work is focused on presenting a new approach to dispersion models of radioactive pollutants, that is, pollutants that undergo chemical reactions. The model uses the two-dimensional advection-diffusion-reaction equation to represent the dispersion of the pollutant in the Atmospheric Boundary Layer and to denote the chemical reaction that the pollutant suffers is included a source term in the advection-diffusion equation.
