What is the best additive to use at the ensiling of sugarcane SP81-3250?

Our objective was to determine the best additive to use for the ensiling of sugarcane SP81-3250 based on the nutritional properties and aerobic stability of the silages. The additives evaluated were (1) and (2): salt (NaCl) at rates of 1.0 or 2.0 kg/100 kg fresh sugarcane (as-is basis), respectively; (3) and (4): quicklime (CaO) at rates of 1.0 or 2.0 kg/100 kg fresh sugarcane, respectively; (5) and (6): commercial inoculants Silobac (R) and Maize All (R); and a control treatment. The addition of quicklime reduced the NDF and ADF contents of the silages by 11% compared with the control treatment, but did not increase the digestibility. On the other hand, after 24 h of in vitro fermentation, the application of 1.0 and 2.0% salt reduced the gas production by 34.15 and 33.55 mL/g OM, respectively, and the IVOMD was reduced 5.74 and 5.90%, respectively, compared with the untreated silage. Moreover, the addition of quicklime elevated the pH of the sugarcane silages, with a trend towards an increase in the DM recovery. In contrast, the bacterial inoculants did not alter the pH values, but there was an upward trend for a DM recovery. After the silos were opened, the silages that were treated with salt (independent of the dose) and 1.0% quicklime exhibited greater stability. We recommend applying 1.0 kg of quicklime to each 100 kg of sugarcane at the time of ensiling to improve the nutritional characteristics of sugarcane silage variety SP81-3250.

Determining large scale actual evapotranspiration using agro-meteorological and remote sensing data in the northwest of Sao Paulo State, Brazil

The best irrigation management depends on accurate estimation of reference evapotranspiration (ET0) and then selection of the appropriate crop coefficient for each phenological stage. However, the evaluation of water productivity on a large scale can be done by using actual evapotranspiration (ETa), determined by coupling agrometeorological and remote sensing data. This paper describes methodologies used for estimating ETa for 20 centerpivots using three different approaches: the traditional FAO crop coefficient (K-c) method and two remote sensing algorithms, one called SEBAL and other named TEIXEIRA. The methods were applied to one Landsat 5 Thematic Mapper image acquired in July 2010 over the Northwest portion of the Sao Paulo State, Brazil. The corn, bean and sugar cane crops are grown under center pivot sprinkler irrigation. ET0 was calculated by the Penman-Monteith method with data from one automated weather station close to the study site. The results showed that for the crops at effective full cover, SEBAL and TEIXEIRA's methods agreed well comparing with the traditional method. However, both remote sensing methods overestimated ETa according to the degree of exposed soil, with the TEIXEIRA method presenting closer ETa values with those resulted from the traditional FAO K-c method. This study showed that remote sensing algorithms can be useful tools for monitoring and establishing realistic K-c values to further determine ETa on a large scale. However, several images during the growing seasons must be used to establish the necessary adjustments to the traditional FAO crop coefficient method.

A ansiedade em bailarinos

This research aims to cover publications related to anxiety suffered by dancers and then to compare their psychological health promotion. This study was developed according to Capes, Scilelo and Google Scholar data basis, besides Sports and Dance Psychology books .These studies state that dance leads its practitioner to increase his self-perception, combined with body and mind work ,as long as the dancer’s limits and possibilities are respected. However, the fear of frustration, exhibition nervousness and expectations can trigger anxiety growth in moments of tension, such as performances. It shows that anxiety can interfere the dancer’s performance in a positive or negative way. It is also believed that, in a general way, his best performance can be achieved when he gets to a proper level of anxiety, which varies from person to person. A lot of authors mention different ways to promote a better balance of anxiety during dance sessions, developing students’ self-confidence, motivation, breathing and recuperation, besides using the benefits from dancing to improve practitioners’ body and mind health.This area lacks more specific studies to let new techniques be created and used by directors and dance companies, to enrich more and more the work of dancers’ emotional balance

Discurso e motivação: um estudo semiótico sobre livros de autoajuda de desenvolvimento profissional

The success and recognition for their dedication put into the work are the need of every worker, and for that there is a constant quest for success in organizations. In this scenario, the Brazilian publishing market offers self-help literature as a practical method of acquiring the fundamental knowledge for professional development. The self-help literature for professional development addresses motivation as an essential characteristic for success, as a motivated worker earns more visibility and prominence to motivate other team members, thus arousing a spirit of leadership among the players. The motivation of workers also meets the expectations of organizations, because they improve productivity without requiring new investments. Thus, the literature on professional development is positioned as one of the best selling literary styles sold in Brazil over the years. To have an understanding of the discourse of literary style and persuasive methods known in them, we present a semiotic analysis of the five introductory chapters of selected works. Greimassian Semiotics offers great tools for understanding the introductory speeches of professional development books, which are intended to present the synthesis of the work, or demonstrate the values and knowledge of the authors, coaxing the reader to read on and be receptive to the idea of motivation presented in the books

A norma-padrão Europeia e a mudança linguística na Escola Moçambicana

In Mozambique, the portuguese language is considered the official language, second language, national language and competes with more than twenty Bantu languages spoken by the majority of population. The standard norm lose away their floor to the Mozambican Portuguese which carries own characteristics pertaining to the sociolinguistic context of the country. Schools attempt their best, but they cannot teach the European standard due the multilingual and Portuguese contact with African languages, a fact that is reflected in the media and in the literature through their oral and written forms. These difficulties result in high rates of failures due to problems encountered in using the European standard by teachers and writers who prepare the school books. This research suggests the standardization of the Mozambican variant as well as the preparation of dictionaries and grammars illustrating the sociolinguistic reality of Mozambique in order to improve the quality of education. It also emphasizes the need for a self-esteem spirit on Mozambicans in general as a conduit to eliminate the soaring bias that Mozambicans can not speak portuguese language

Q-angle static or dynamic measurements, which is the best choice for patellofemoral pain?

The elevated Q-angle seems to be one of the most suggested factors contributing to patellofemoral pain. Females with patellofemoral pain are often evaluated through static clinical tests in clinical practice. However, the adaptations seem to appear more frequently in dynamic conditions. Performing static vs. dynamic evaluations of widely used measures would add to the knowledge in this area. Therefore, the aim of this study was to determine the reliability and discriminatory capability of three Q-angle measurements: a static clinical test, peak dynamic knee valgus during stair ascent and a static measurement using a three-dimensional system. Twenty-nine females with patellofemoral pain and twenty-five pain-free females underwent clinical Q-angle measurement and static and dynamic knee valgus measurements during stair ascent, using a three-dimensional system. All measurements were obtained and comparisons between groups, reliability and discriminatory capability were calculated. Peak dynamic knee valgus was found to be greater in the patellofemoral pain group. On the other hand, no significant effects were found for static knee valgus or clinical Q-angle measurements between groups. The dynamic variable demonstrated the best discriminatory capability. Low values of reliability were found for clinical Q-angle, in contrast to the high values found for the three-dimensional system measurements. Based on our findings, avoiding or correcting dynamic knee valgus during stair ascent may be an important component of rehabilitation programs in females with patellofemoral pain who demonstrate excessive dynamic knee valgus. Q-angle static measurements were not different between groups and presented poor values of discriminatory capability.

Aedes aegypti proliferation in stormwater retained in Best Management Practices

The present study aimed to evaluate the risk of Aedes aegypti proliferation in structures used in compensatory techniques for urban drainage (Best Management PracticesBMPs). These drainage structures are utilised to reduce flood peaks due to surface runoff, and they have been used in many countries. However, many of these structures have been designed to keep water surfaces exposed for a certain period of time, depending on the type of project. Exposed water surfaces may become an ideal environment for A. aegypti proliferation in tropical and subtropical areas where the rainy season occurs during the summer. Thus, data regarding the mosquito life cycle, consecutive rainfall pattern and emptying time of these structures were collected. A comparison of these data led to the evaluation of the associated risk of A. aegypti proliferation in BMP structures. The risk of mosquito proliferation ranged from 1.1% to 3.3%, depending on the rainfall pattern, A. aegypti life cycle phase and BMP activity.

Evaluation of the best-designed graded exercise test to assess peak treadmill speed

This study examined the influence of different speed increments during treadmill exercise tests on peak treadmill speed (Vpeak) and its relationship with a 1-h treadmill running performance. 18 male recreational and amateur runners (10-km running pace: 10–15 km·h−1) performed, in an alternate order, 3 continuous incremental exercise tests with different speed increments (0.5, 1.0 and 2.0 km·h−1) on a motorized treadmill to determine Vpeak. Thereafter they undertook a 1-h time trial on a treadmill. Vpeak was determined as either (a) the highest speed that could be maintained for a complete minute (Vpeak-60 s), (b) the speed of the last complete stage (Vpeak-C), or (c) the speed of the last complete stage added to the product of the speed increment and the completed fraction of the incomplete stage (Vpeak-P). The Vpeak values were highly influenced by the different speed-incremented rates and the Vpeak-P determined during the protocol comprising speed increments of 1 km·h−1 presented the highest correlation with 1-h time trial performance (r=0.89). The results suggest that a protocol with speed increments comprising 1 km·h−1 and with a 3-min stage duration should be used as standard for the determination of Vpeak to assess aerobic fitness and predict endurance performance in recreational runners. Furthermore, the Vpeak-P should be used for the determination of Vpeak.

Estados emocionais e atividade física em idosos: contribuições da literatura brasileira

This study with qualitative nature aims to analyze the impact of external factors on mood states, considering physical activity as an important factor to improve not only the physical, but also psychological factors, especially when we think of the activities performed in-group. Thus, a literature review was conducted in order to investigate in books, journals, scientific papers published in magazines, newspapers and electronic platforms the influence of exercise on emotional states of elderly people. The terms used across the curriculum contributed to the conformity of ideas on the subject. By checking some researches, it can be seen that external factors such as music, local infrastructure, professional relationship with the elderly people and other factors have been suggested as possible influencers of humor in physical activity. Knowing the preferences beyond the close contact with the elderly student, is the best way to affect possible aspects of the activity beyond just preventing circumvention of activity, avoiding sedentary lifestyle that will bring risks to the health of the elderly people

Undergraduate Scholarship in the College of Arts and Sciences 2003 Book of Abstracts

On behalf of the faculty, staff, and students in the College of Arts and Sciences, I want to thank you for your interest in this collection of abstracts of undergraduate research for 2003. This collection is the first we have published, and we expect it to be number one in a long and increasingly impressive series. The importance of this collection is what it represents. These abstracts are the results of untold hours of hard work by students and faculty. Through that work, students have learned much about the research process, developed important critical and analytical thinking skills, improved writing abilities, and deepened relationships with faculty mentors. Many students have presented their research in classes, through seminars, and at professional meetings. In this work, faculty have been challenged to push students to do the best they can, to let them flounder as they struggle to solve the problems at hand, to hold them to deadlines, and to know how to encourage and when to scold. I know from personal experience that working together on meaningful research is a powerful way to build lasting relationships between students and faculty members.
