13. Production of mycelial biomass by the Amazonian edible mushroom Pleurotus albidus
ABSTRACT Edible mushroom species are considered as an adequate source of food in a healthy diet due to high content of protein, fiber, vitamins, and a variety of minerals. The representatives of Pleurotus genus are characterized by distinct gastronomic, nutritional, and medicinal properties among the edible mushrooms commercialized worldwide. In the present

14. A Heuristic Algorithm Based on Line-up Competition and Generalized Pattern Search for Solving Integer and Mixed Integer Non-linear Optimization Problems
Abstract The global optimization of integer and mixed integer non-linear problems has a lot of applications in engineering. In this paper a heuristic algorithm is developed using line-up competition and generalized pattern search to solve integer and mixed integer non-linear optimization problems subjected to various linear or nonlinear constraints. Due to i

15. A new enzymatic process for the treatment of phenolic pollutants
This work aimed to develop a new economic enzymatic process to treat the phenolic pollutants using pure tyrosinase in stirred vessel and adopting temperature (T), pH, rotational speed (N), initial phenol (C P,o) and enzyme (C T) concentrations as independent variables. Experimental data of the residual phenol concentration (C P) were used to calculate the ox

16. Analysis of parameters effects on crack breathing and propagation in shaft of rotor dynamic systems
In this paper the design of experiment method is used to investigate and explain the effects of the rotor parameters on crack breathing and propagation in the shaft. Three factors are considered which have an influence on the behavior and the propagation of the crack: the rotational speed, the length of the rotor and the diameter of the shaft. The elaborated

17. Variabilidade da frequência cardíaca após treinamento concorrente : comparação entre homens e mulheres de meia-idade = Heart rate variability after concurrent training : comparison between middle-aged men and women / Heart rate variability after concurrent training : comparison between middle-aged men and women
The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing

18. Optimization of flask culture medium and conditions for hyaluronic acid production by a streptococcus equisimilis mutant nc2168
A mutant designated NC2168, which was selected from wild-type Streptococcus equisimilis CVCC55116by ultraviolet ray combined with60Co-γ ray treatment and does not produce streptolysin, was employed to produce hyaluronic acid (HA). In order to increase the output of HA in a flask, the culture medium and conditions for NC2168 were optimized in this study. The

19. Selection of optimal process parameters for minimizing burr size in drilling using Taguchi's quality loss function approach
The exit burr in drilling degrades the precision of products and causes additional cost of deburring. Therefore, it is essential to minimize burr size at the exit of holes in drilling at the manufacturing stage. Taguchi's quality loss function approach, a multi-response optimization method, has been employed to determine the best combination values of cuttin

20. A generic and open framework for multiword expressions treatment : from acquisition to applications
The treatment of multiword expressions (MWEs), like take off, bus stop and big deal, is a challenge for NLP applications. This kind of linguistic construction is not only arbitrary but also much more frequent than one would initially guess. This thesis investigates the behaviour of MWEs across different languages, domains and construction types, proposing an

21. Metas entre Estado e mercado nas compras públicas
It is known that the State does not produce all the goods that he needs to meet their demands, requiring resort to the private sector. Thus, the buying public are a matter of clear importance to all those who are connected in all spheres of public administration. There is some consensus on the need for changes in the public procurement system in Brazil in or

22. Efeitos da inclinação do terreno e da carga sobre o trabalho mecânico e o custo de transporte na caminhada humana / Effects of gradient and load on the mechanical work and the cost of transport in human walking
O objetivo do presente estudo foi comparar o comportamento dos parâmetros mecânicos (Wext, Wint, Wtot, CP, FP), parâmetros energéticos (Pmet, C, Eff, Vótima) e do mecanismo pendular (R, Rint, %Cong) durante a caminhada com carga no plano (0%), nas inclinações (+7% e +15%) e em distintas velocidades de caminhada. A amostra foi composta por 10 homens jo

23. Condições de armazenamento e conservação do potencial fisiológico de sementes de diferentes genótipos de milho / Storage conditions and seed performance of different corn genotypes
Seed storability is affected by several factors including genotype and environmental conditions. Corn seed producers are highly concerned with variations in seed longevity of different hybrids, resulting in lower performance than desired during the normal sowing season as much as during off season times. The objective of this research was to evaluate the eff
