13. Agronomic and molecular characterization of wild germplasm Saccharum spontaneum for sugarcane and energycane breeding purposes
ABSTRACT: Among the species related to sugarcane, Saccharum spontaneum (L.) is a wild species with the greatest potential as a source of genetic variation to cope with biomass production in harsh environments. Due to its high yield, early vigor, ratooning ability, low input requirements and tolerance to various biotic and abiotic stresses, sugarcane breeders

14. A simple organized approach for balancing nuclear equation
Abstract This paper reports on the development of a simple organized approach for balancing a given nuclear equation in which all the reactants and products appear explicitly. A novel general algorithm for finding the balanced form of a nuclear equation has been offered for the said purpose. It has been found that, in addition to having the physically admiss

15. ABORDAGEM DIDÁTICA PARA O DESENVOLVIMENTO DE MOLÉCULAS BIOATIVAS: REGRA DOS CINCO DE LIPINSKI E PREPARAÇÃO DE HETEROCICLO 1,3,4-OXADIAZOL EM FORNO DE MICRO-ONDAS DOMÉSTICO
In Brazil, the development of new chemical entities (NEQ) is still limited to small advances in the academic and public research sectors, the authors understand that this is a sector of the pharmaceutical industry that needs encouragement. Accepting that education transforms society, educate students in the development of bioactive molecules, it’s a way to

16. Fourier analysis of nonlinear pendulum oscillations
Since the times of Galileo, it is well-known that a simple pendulum oscillates harmonically for any sufficiently small angular amplitude. Beyond this regime and in absence of dissipative forces, the pendulum period increases with amplitude and then it becomes a nonlinear system. Here in this work, we make use of Fourier series to investigate the transition f

17. How does practice improve the skills of medical students during consecutive training courses?
Abstract Purpose: To follow-up the development of medical students in taking a stitch using two different bench models, and to assess their performance with regards to gender, handedness, prior recreational activities and interest in surgery. Methods: The study was performed during the compulsory basic (n=152) and the consecutive elective course (n=27). St

18. Development and Evaluation of a Controlled Release System of TBH Herbicide Using Alginate Microparticles
The development of controlled delivery system formulations has received increasing interest in the agriculture area. Tebuthiuron (TBH) is the most commonly used herbicide for weed control in sugar cane and cotton crops. The TBH and some of its metabolites are detected in surface water by leaching process, evidencing contamination and the need for an efficien

19. Evaluation of the Residual Stress State of 42crmo4 Steel Sheets in a Production Line
The residual stress state of a mechanical component is an important factor in its production planning and in estimates of its lifecycle since it can be responsible for geometric distortions and degradation of fatigue properties. Therefore, the development of reliable methods for non-destructively quantifying these stresses remains in the interest of most man

20. CHARACTERIZING THE MECHANISM OF QUETIAPINE DISTRIBUTION IN LIPID-CORE NANOCAPSULES PSEUDO-PHASES USING A VALIDATED LC/UV METHOD
Quetiapine is an atypical antipsychotic used to treat schizophrenia. However, despite great interest for its chronic therapeutic use, quetiapine has some important side effects such as weight gain induction. The development of a quetiapine nanocarrier can potentially target the drug into central nervous system, resulting in a reduction of systemic side effec

21. Purification procedure for the isolation of a P-I metalloprotease and an acidic phospholipase A 2 fromBothrops atrox snake venom
Background Snake venoms are complex mixtures of inorganic and organic components, mainly proteins and peptides. Standardization of methods for isolating bioactive molecules from snake venoms is extremely difficult due to the complex and highly variable composition of venoms, which can be influenced by factors such as age and geographic location of the specim

22. Solar ultraviolet radiation: properties, characteristics and amounts observed in Brazil and South America
Abstract The beneficial and harmful effects of human exposure to solar ultraviolet radiation (UV-R) are topics that arouse great interest not only among physicians and scientists, but also the general public and the media. Currently, discussions on vitamin D synthesis (beneficial effect) are confronted with the high and growing number of new cases of non-mel

23. Critical Assessment of the Surface Tension determined by the Maximum Pressure Bubble Method
The main factors that influence the value of surface tension of a liquid measured with the Maximum Pressure Bubble Method are critically evaluated. We present experimental results showing the effect of capillary diameter, capillary depth, bubble spheroidicity and liquid density at room temperature. We show that the decrease of bubble spheroidicity due to inc

24. Comparison between electrospun and Bubbfil-spun Polyether sulfone fibers
Electrospinning is a simple method for producing ultrafine fibers, and has attracted much recent interest. The classical approach was either polymer solutions or polymer melts. Bubbfil spinning (e.g. bubble-electrospinning) is a facile method to fabricate nanofibers with high surface area to volume ratio and high porosity. Polyether sulfone (PES) dissolved i
