ABSTRACT

The possible association between disorders of the femoropatellar joint and geometrical anatomical variations in the patellar facet and femoral sulcus motivated us to conduct a morphometric study on the angle of the femoral sulcus and to correlate this with possible variation factors, such as: length, width at the midpoint of the femur, femur inclination angle, distance between condyles and depth of the patellar facet. The material consisted of 56 dry femurs of both sexes and various ages: 24 from the right side and 32 from the left side. The patellar facets were photographed at three positions: a) start level; b) middle level; and c) end level. The angle formed in each of these positions was measured using graphical tools in CorelDraw X4. To analyze the results, the statistical tests used were chi-square and Student’s t-test for correlations. The results obtained were: a) angle of the patellar facet: mean for start level of the patellar facet = 129°01; mean for middle level = 131°35 and mean for end level = 132°14; b) mean distance between condyles = 50.29  mm; c) mean depth of the patellar facet = 9.55 mm; d) mean for Ficat and Bizou’s condylar depth index = 5.45. We concluded that the angle of the femoral sulcus increased from the start of the patellar facet to its end, and that its variability was weakly influenced by the length, width, femur inclination angle and side, according to the t-test (significance of 5%) for the correlation coefficients found.

ABSTRACT

A brief review about the historical evolution of seed technology research in Brazil is presented, pointing out the most important facts that contributed to the development of our seed production complex and research system. The role of PLANASEM and AGIPLAN and their cooperative projects with UFPEL, ESALQ and Mississippi State University is mentioned. Major seed related publications and events, such as seminars and congresses, which contributed to the development of seed research are included and analyzed. A survey of the most important lines of seed technology research conducted in Brazil is presented. Additionally, the Brazilian universities and research institutions that significantly contributed to seed research in the past 30 years are identified. Possible tendencies and perspectives for seed research in the next five years are conjectured.


Apresenta-se uma síntese da evolução histórica da pesquisa em tecnologia de sementes no Brasil, destacando os fatos mais importantes que contribuíram para o desenvolvimento dos sistemas de produção e de pesquisa. O papel do PLANASEM e do AGIPLAN e seus projetos cooperativos com a UFPEL, a ESALQ e com a Universidade Estadual do Mississippi são abordados. As principais publicações da área de sementes e os mais importantes eventos, como seminários e congressos, que efetivamente contribuíram para o desenvolvimento da pesquisa em sementes, são destacados e analisados. Um levantamento das principais linhas de pesquisa em tecnologia de sementes realizadas no Brasil é apresentado. Além disso, são identificadas as universidades e demais instituições de pesquisa que mais contribuíram, nos últimos 30 anos, para o progresso da pesquisa em sementes no Brasil. Tendências e perspectivas para a pesquisa brasileira em sementes para os próximos cinco anos são conjeturadas.
