Abstract: O objetivo deste estudo foi avaliar a rea o de dois cultivares de trigo aos danos causados por percevejos adultos de Dichelops melacanthus (Dallas), confinados sobre a cultura a partir do início do perfilhamento. Foram comparados os efeitos de diferentes níveis de infesta o (0, 2, 4, 8 e 16 percevejos m-2) sobre o número de perfilhos m-2, número de espigas m-2, peso de mil sementes (g) e rendimento (kg ha-1) das cultivares ?BR 18' e ?BRS 193' de trigo, em Londrina, PR. O número de perfilhos m-2 cresceu linearmente para a cv. ?BR 18' e de forma quadrática para a cv. ?BRS 193' com o aumento do número de percevejos m-2; o número de espigas m-2, o peso de mil sementes, e o rendimento decresceram de forma linear com o aumento do nível de infesta o para as duas cultivares. ?Acv.BRS 193' foi mais suscetível ao ataque de D. melacanthus, apresentando uma redu o de 254,4kg para cada unidade de aumento no número de percevejos m-2.

Scientia Agricola , 2010, DOI: 10.1590/S0103-90162010000100012
Abstract: the alydid bug parvus (westwood) is not easily detected in the field and the discovery of attractants may be a suitable way to monitor this species. the attraction of n. parvus to traps (transparent, transparent green and yellow) baited with cow urine and ammonia was studied in two field trials. traps were placed near a terrace with pigeon pea plants (cajanus cajan l.). tap water, nacl 10% aqueous solution (w/v), cow urine, and ammonia (nh4oh 1% aqueous solution) were tested as attractants in yellow, transparent and transparent green traps. green traps baited with cow urine caught more bugs than yellow and transparent traps (3.2 and 7.2 times more, respectively), and more bugs than traps of the same color with just water (no captures) or nh4oh solution (14.5 times more). traps baited with ammonia caught more bugs than traps with water: 14.4, 4.7 and 6.7 times more than transparent green, yellow, and transparent traps, respectively, or nacl solution: 3.9, 7.6 and 6.2 times, respectively. both ammonia and cow urine are attractive to n. parvus and may be tested to monitor the bugs in the field.

O mundo antigo visto por lentes contemporaneas: as extremas direitas na Fran?a nas décadas de 1980 e 90, ou da instrumentalidade da Antigüidade
Silva, Glaydson José da;
História (S?o Paulo) , 2007, DOI: 10.1590/S0101-90742007000100008
Abstract: this work analyses the uses of the ancient world by right-wing french extremists as means to establish comprehensions of the contemporary world, aiming at the legitimization of rights derived from origin. it proposes a reflection upon the role of the past in relation to the strategy games and identity affirmations based on the instrumentalization carried out by analyzed groups (grece, front national and terre et peuple). this work was developed considering the premise that the past, its writings and readings are powers and generate powers.
Variabilidade do número de internódios e altura da espiga em linhagens e híbridos de milho
Silva, William José da;

Abstract: most of the maize cultivars grown in the state of s?o paulo and the cultivars imported from other tropical regions although vigorous have highly inserted ears. this fact makes the manual and mechanical harvesting operations difficult. in order to get preliminary information about the inheritance of this characteristic, two series of data were collected in campinas, related to the number of internodes from the bottom of the plant to the main ear insertion and the ear height. a coeficient of variation of 4.4 per cent was obtained for the number of internodes in seven inbred lines of flint and dent corn. the coefficients for 8 single crosses and 8 double cross hybrids of the lines were 3.4 and 5.9 per cent, respectively. for the ear height in the same lines and crosses the coefficients of variation were 13.3; 9.0 and 16.0 per cent, respectively. the comparison of the internode number and its lenght indicates that the former is less influenced by the environment than the latter and can be advantageously taken into consideration in the selection for plants with low ear height. it is also suggested, based on the lines and hybrids analysed, that the internode number is controlled by factors without dominance while the ear height is conditioned by factors having heterotic effect.

Pelvic lymphoscintigraphy: contribution to the preoperative staging of rectal cancer
Silva, José Hyppolito da;
Revista do Hospital das Clínicas , 2002, DOI: 10.1590/S0041-87812002000200002
Abstract: purpose: preservation of the anal sphincter in surgery for cancer of the distal rectum in an attempt to avoid colostomy has been a main concern of colorectal surgeons. various proposed procedures contradict oncological principles, especially with respect to pelvic lymphadenectomy. therefore, prior knowledge of pelvic lymph node involvement is an important factor in choosing the operative technique, i.e., radical or conservative resection. introduction of ultrasound, computerized tomography, and magnetic resonance have made preoperative study of the area possible. nevertheless, these resources offer information of an anatomical nature only. lymphoscintigraphy enables the morphological and functional evaluation of the pelvic area and contributes toward complementing the data obtained with the other imaging techniques. the objective of this prospective study is twofold: to standardize the lymphoscintigraphy technique and to use it to differentiate patients with rectal cancer from those with other coloproctologic diseases. casuistic and methods: sixty patients with various coloproctologic diseases were studied prospectively. ages ranged from 21 to 96 years (average, 51 and median, 55 years). twenty-six patients were male and 34 were female. thirty patients had carcinoma of the distal rectum as diagnosed by proctologic and anatomic-pathologic examinations, 20 patients had hemorrhoids, 5 had chagasic megacolon, 2 had diverticular disease, 2 had neoplasm of the right colon, and 1 had ulcerative colitis as diagnosed by proctologic exam and/or enema. the lymphoscintigraphy method consisted of injecting 0.25 ml of a dextran solution marked with radioactive technetium-99m into the right and left sides of the perianal region and obtaining images with a gamma camera. the results were analyzed statistically with a confidence level of 95% (p < .05) using the following statistical techniques: arithmetic and medium average, fisher exact test, chi-square test corrected for continuity

Abstract: the present report aims to show the experience of the national network of afro-brazilian religions and health in the construction of a partnership with sus (national health system), the therapeutic practices used by the terreiros and the relationships of the afro-brazilian religiosity to injuries and diseases. the importance of body care to the afro-brazilian religions was the point-of-departure to carry out the experience of acting in network. in this experience, the leaderships of african religions underwent situations that promoted the understanding of the functioning of the national health system/sus, the evaluation of the services provided for the population, and the recognition of the importance of the social control of public health policies. the report also shows the establishment of an interlocution channel that promoted an approximation between the priests and priestesses of the afro-brazilian religious tradition and the health managers and professionals, facilitating the dialog and the proposition of health actions, respecting the culture and worldview of the terreiros. finally, it presents some results and challenges faced by the national network of afro-brazilian religions and health in its trajectory of actions in partnership with sus.
