Hip hop na escola: para além da proposta curricular do Estado de São Paulo

Since 2008 the Department of Education of the State of São Paulo implemented the curriculum for elementary and high school. Within the discipline of Physical Education, Hip Hop appears as a theme for the ninth year pertaining to the content of rhythmic activities. However, there seems to be difficulties of teachers and their training against such content. Therefore, this research has developed a textbook to support didactic teaching for physical education teacher about Hip Hop in school. For this we conducted a literature review, which were selected several studies that sought to investigate the main difficulties of the physical education teachers, as well as those who had the Hip Hop theme, so that the material could meet the real difficulties of these professionals. Furthermore, we analyzed textbooks from other disciplines will be considered as the experiences of the researcher with the contents of dancing. Thus, we found some difficulties in the analysis of textbooks in the area of Physical Education, since there is a certain shortage of materials, as well as related specifically to Hip Hop. From the investigations, the book was prepared by selecting subtopics important to treat this content teachers in the school, for example, the story, the basic features and steps. It is understood, therefore, that this type of work is very important for Physical Education Teachers considering the difficulties facing the contents of Hip Hop and can contribute more effectively to their inclusion in the school context

Hip Hop na aula de FLE: aprendendo e ensinando o léxico não-padrão

Appuyé sur le concept de lexiculture, proposé par R. Galisson (2000), et en reconnaissance de l’existence et de la dimension du mouvement Hip Hop en France, le but de cet article est d’examiner l’importance de cette culture et de son lexique dans le contexte français, soulignant aussi la nécessité de son insertion dans les matériels éducatifs destinés à l’enseignement du français langue étrangère (FLE). À cet effet, nous avons elaboré, à l’aide d’un système de traitement de corpus, une liste bilingue français-portugais brésilien de ce lexique, à partir des paroles des trois principaux artistes français. Il faut noter que la plupart de ces unités lexicales ne sont pas présentes dans les dictionnaires généraux bilingues, ce qui crée des difficultés aux apprenants ainsi qu’aux enseignants d’accès à ce lexique, qui coexiste avec la langue standard étudiée et qui représente une grande richesse linguistique.

Vitamin D serum levels are associated with handgrip strength but not with muscle mass or length of hospital stay after hip fracture

Objectives: The aim of this study was to evaluate the association between serum levels of 25(OH) vitamin D-3 with midupper arm muscle circumference (MUAMC), handgrip strength and length of hospital stay (LOS) after hip fracture.Methods: In total, 102 consecutive patients with hip fracture over the age of 65 were admitted to the orthopedic unit and prospectively evaluated. All of the patients were treated according to specific protocols depending on the type of fracture. Anthropometric measurements and handgrip strength were performed, and blood samples were taken for serum biochemistry and 25(OH) vitamin D-3 analysis within the first 72 h of admission. All of the patients were followed during their hospital stay, and the length of stay was recorded.Results: Of the patients, two were excluded because of pathologic fractures. In total, 100 patients with a mean age of 80 +/- 7 y were included in the analysis. Among these patients, 73% were female, and 37% had vitamin D deficiency. The median LOS was 7 (5-11) d. Patients with vitamin D deficiency had lower handgrip strength in univariate analysis. In the multiple linear regression analysis with robust standard error, serum vitamin D levels adjusted by age and sex were associated with handgrip strength but not with MUAMC and LOS after hip fracture.Conclusions: In conclusion, vitamin D serum levels were associated with handgrip strength but not with muscle mass or length of hospital stay after hip fracture.

First insight on the impact of an osteoblastic layer on the bio-tribocorrosion performance of Ti6Al4V hip implants

In uncemented Ti6Al4V hip implants, the bone-stem interface is subjected to cyclic loading motion driven by the daily activities of the patients, which may lead to the complete failure of the implant in the long term. It may also compromise the proliferation and differentiation processes of osteoblastic cells (bone-forming cells). The main objective of this work is to approach for the first time the role of these organic materials on the bio-tribocorrosion mechanisms of cultured Ti6Al4V alloys. The colonized materials with MG63 osteoblastic-like cells were characterized through cell viability/proliferation and enzymatic activity. Tribocorrosion tests were performed under a reciprocating sliding configuration and low contact pressure. Electrochemical techniques were used to measure the corrosion kinetics of the system, under free potential conditions. All tests were performed at a controlled atmosphere. The morphology and topography of the wear scar were evaluated. The results showed that the presence of an osteoblastic cell layer on the implant surface significantly influences the tribocorrosion behavior of Ti6Al4V alloy. It was concluded that the cellular material was able to form an extra protective layer that inhibits further wear degradation of the alloy and decreases its corrosion tendency.

Ultra-precision face grinding with constant pressure, lapping kinematics, and SiC grinding wheels dressed with overlap factor

Several machining processes have been created and improved in order to achieve the best results ever accomplished in hard and difficult to machine materials. Some of these abrasive manufacturing processes emerging on the science frontier can be defined as ultra-precision grinding. For finishing flat surfaces, researchers have been putting together the main advantages of traditional abrasive processes such as face grinding with constant pressure, fixed abrasives for two-body removal mechanism, total contact of the part with the tool, and lapping kinematics as well as some specific operations to keep grinding wheel sharpness and form. In the present work, both U d-lap grinding process and its machine tool were studied aiming nanometric finishing on flat metallic surfaces. Such hypothesis was investigated on AISI 420 stainless steel workpieces U d-lap ground with different values of overlap factor on dressing (Ud=1, 3, and 5) and grit sizes of conventional grinding wheels (silicon carbide (SiC)=#800, #600, and #300) applying a new machine tool especially designed and built for such finishing. The best results, obtained after 10 min of machining, were average surface roughness (Ra) of 1.92 nm, 1.19-μm flatness deviation of 25.4-mm-diameter workpieces, and mirrored surface finishing. Given the surface quality achieved, the U d-lap grinding process can be included among the ultra-precision abrasive processes and, depending on the application, the chaining steps of grinding, lapping, and polishing can be replaced by the proposed abrasive process.

Rap Music and Hip Hop on Amerian College Campuses

My session will cover how many young African Americans believe that Rap music and Hip Hop is more important and relevant today on college campuses than the Civil Rights movement, or learning about the great works'. But one must seriously question whether Rap music and/or the Hip Hop culture is more significant than the movement that gave most Americans in the United States a modicum of equally in our institutionally racist society.

Kinematics and Energetics of Nut-Cracking in Wild Capuchin Monkeys (Cebus libidinosus) in Piaui, Brazil

Wild bearded capuchins (Cebus libidinosus, quadrupedal, medium-sized monkeys) crack nuts using large stones. We examined the kinematics and energetics of the nut-cracking action of two adult males and two adult females. From a bipedal stance, the monkeys raised a heavy hammer stone (1.46 and 1.32 kg, from 33 to 77% of their body weight) to an average height of 0.33 m, 60% of body length. Then, they rapidly lowered the stone by flexing the lower extremities and the trunk until the stone contacted the nut. A hit consisting of an upward phase and a downward phase averaged 0.74 s in duration. The upward phase lasted 69% of hit duration. All subjects added discernable energy to the stone in the downward phase. The monkeys exhibited individualized kinematic strategies, similar to those of human weight lifters. Capuchins illustrate that human-like bipedal stance and large body size are unnecessary to break tough objects from a bipedal position. The phenomenon of bipedal nut-cracking by capuchins provides a new comparative reference point for discussions of percussive tool use and bipedality in primates.
