In subtropical or tropical conditions, the insufficient winter chill accumulation is often a limiting factor to break the dormancy of temperate-climate species such as the blackberry, which requires using products to help break dormancy. This study evaluates the efficacy of compounds in breaking dormancy of blackberry and its consequent influence on phenology and crop yields. The experiment was conducted in S?o Manuel, State of S?o Paulo, Brazil, in the 2011/2012 production cycle. The plants used were two-year-old “Tupy” blackberry (Rubus spp.), with 0.6 × 4.0 m spacing (4.166 plants·ha-1). Pruning was performed in August, followed by the application of these treatments: control (water);hydrogen cyanamide (Dormex?);nitrogen fertilizer (Erger?) and mineral oil (Assist?). The concentrations of each compound used were: 2.0%, 4.0%, 6.0% and 8.0%. The compounds used influenced the budding, flowering and fruit harvest stages, in addition to providing increased yields depending on the concentration used. For hydrogen cyanamide the recommended concentration is of 4.2% and 5.4% for nitrogen fertilizer;doses above these concentrations may cause phytotoxic effects. For mineral oil the dose recommended is of 8.0%.

Chemical and biological insecticides have been frequently used in sugarcane fields to control insects-pests, including the sugarcane borer, Diatraea saccharalis. Among the products used, those based on chlorantraniliprole and Metarhizium anisopliae entomopathogenic fungus, stand out. Euborellia annulipes is an insect of the order Dermaptera considered a potential predator of sugarcane borer eggs. This study aimed to evaluate the direct and indirect effects of the bioinsecticide based on M. anisopliae (Metarril®) and the chemical insecticide chlorantraniliprole (Altacor®) on the mortality of E. annulipes nymphs and adults, the predation and feeding preference of earwigs in eggs treated with the formulated products. Predator mortality was evaluated for seven days after treatment, while the effect on predation was analyzed by preference tests with and without choice, using prey eggs. The products tested were selective to the predator, causing ≤ 2% mortality and not affecting predation. The application of M. anisopliae on sugarcane borer eggs favored the food preference of fourth-instar nymphs, males, and females of the predator. Our results show that Metarril® and Altacor® can be used to control D. saccharalis when associated with the predator E. annulipes.

Origanum vulgare L. (oregano) and Rosmarinus officinalis L. (rosemary) are vegetal species belonging to the family Lamiaceae, popularly known as oregano and rosemary. Aromatic plants are used in the treatment and prevention of diseases and in the culinary as functional food in the preparation and conservation of foods. In the chemical composition of oregano and rosemary are present bioactive compounds with antimicrobial, antioxidant and flavoring effect. Several reports in the literature have presented the chemical composition and biological activity of the essential oils of oregano and rosemary. However, few studies have been carried out regarding the chemical composition and biological potential of the aqueous and ethanolic extracts of Origanum vulgare L. and Rosmarinus officinalis L. Evidencing a need to investigate the chemical composition and antifungal activity of these extracts. The objective of the study was to evaluate the bioactive compounds and antifungal activity of the aqueous and ethanolic extract of Origanum vulgare

Visceral leishmaniasis(VL) or kala-azar is a zoonosis caused by intracellular protozoa of the Leishmania genus and is transmitted to humans by the bite of phlebotomine sandflies. It particularly affects cells in the phagocytic mononuclear system, accompanied by disturbances of cellular and humoral immunity. VL is potentially fatal and is characterized by fever, hepatosplenomegaly, diarrhea, epistaxis, jaundice, anemia, leucopenia, thrombocytopenia, hypoalbuminemia and hyperglobulinemia. Diagnostic suspicion is based on epidemiological, clinical and laboratory data and isconfirmed by detecting the parasite in infected tissue. Splenic aspiration is the most sensitive method, followed by bone marrow aspiration(BMA) by sternal puncture, liver biopsy and lymph node aspiration; but, due to safety concerns, BMA is the most recommended method. VL is included as a target disease by players in drug research and development. Severe liver dysfunction associated with VL is uncommon. We report two VL cases in pregnant women from Bauru, Sao Paulo state, Brazil, considered an endemic area. The first of them developed hepatic failure due to fulminant hepatitis. In both cases, BMA was unable to find the protozoan; thus, liver biopsy was the only means of making the diagnosis.

In 2009, based on a multicenter study conducted in Asia and Latin Americaand subsidized by the Dengue Control (DENCO) Research Program, the World Health Organization (WHO) proposed a new classification for dengue cases. The purpose of the present study was to evaluate the applicability of the new classification, relative to its previous version [1]. The evaluation, conducted in Campo Grande county, Mato Grosso do Sul state, Brazil, drew on secondary data from referral healthcare centers that assist high-severity dengue patients. A total of 156 medical records of patients with laboratory diagnosis of dengue were investigated. The records covered two epidemic periods: summer of 2006-2007 and summer of 2009-2010. The results showed that 64.6% of cases classified as dengue fever under the 1997 criteria presented manifestations of severity, warranting their reclassification as dengue with warning signs (49) or severe dengue (15) under the 2009 revised criteria. Bleeding, persistent vomiting, and severe, continuous abdominal pain were the most prevalent warning signs, indicative of risk of progression to severe disease. The revised classification was proved less complex than the current version, facilitating the identification of cases and the clinical management of patients.

This paper deals with a method for building a mobile robot in order to transform the material into a practical guide for beginners in the study of mobile robotics. The project is divided into layers that can define the topics related to the areas of knowledge that will be used in carrying out the project. These areas are the mechanics, electronics and computing system. The mobile robot named Fable was developed accordingly to this method. It is composed by two active wheels, each one driven by DC motor with a high torque and a transmission system containing two spur gears. It has three sonars for detection of the opponent and two infrared sensors to detect a line and an Arduino Uno board is used to control all the actions of the robot.

To assist in upland rice breeding programs, estimated genetic and phenotypic parameters are extremely important in the selection of superior lines. Thus, the objective of this study was estimate the genetic and phenotypic parameters of upland rice lines of the breeding program of UFLA in partnership with Embrapa Arroz e Feijao and Epamig. The experiment was installed in an experimental area of the Department of Agriculture at UFLA. It was evaluated 36 upland rice lines of the preliminary trial of the 2014/15 season, in randomized blocks, with three replications and plots consisted of five rows and each row has four meters. For this, it was evaluated the characters: plant height (cm), yield (kg·ha-1), 100-grain weight, days until flowering, percentage of filled grains and rice blast severity. The variance analysis and genetic parameters were estimated using the software SAS. To evaluate the experimental precision was estimated the accuracy, which varied between 63% and 98%, showing experimental precision, moderate to high. The lines differed significantly for all characters, meaning there is genetic variability among genotypes evaluated. With intensity of selection of 10% of lines, it was obtained a genetic gain of 325.29 kg·ha-1 in the character productivity, a plant height (cm) reduction in 5.50 cm, and days until flowering, with a reduction of 9.23 days, with selection of earlier plants. The estimated values for heritability ranged from 38% - 96%. Estimates confirm the possible success with the selection of the upland rice lines for these characters.
