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.

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.

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.

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.

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.

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.

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.

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.

Based on resources from the Research and Development Program of the National Electricity Agency (ANEEL), the Pernambuco Energy Company (CELPE) is developing a research project to implement an innovative electrical energy storage system for the Fernando de Noronha. Through the project Multiobjective Optimization of Distributed Energy Resources aimed at Sustainability and Reliability in Isolated Micro grids including Energy Storage System with Batteries, the Environmental Education Program is being implemented in the region.

Teenage pregnancy represents a serious public health issue, both nationally and internationally,being a much debated subject in literature. The objective of this study is to present the characteristics of teenage pregnancy in the community of Curuçambaba, Bujaru-PA.
