The present article deals with the adaptation of the Moral Judgment Test (MJT) for the Portuguese language. The principles of the test, its format and the process of content, construct and criterion validation are presented. In the same way, reliability is discussed using Brazilian research results that produced the necessity of elaborating another dilemma to compose the MJT-xt (extended).

Teste de envelhecimento acelerado em sementes de quiabo

The objective of this research was to study the accelerated aging test to evaluate the okra vigor seed. Were used four okra seed lots cv. "Santa Cruz". The initial seed lot quality was evaluate by the moisture content, germination, first germination count, speed of germination index and seedling emergence. The experiment was carried out in two phases: the first one the seeds were submitted to the accelerate aging with and without NaCl salt solution aging periods of 48, 72, 96 and 120 hours, at 41 and 45(0) C temperature. The second phase the best procedures as for as accelerated aging and temperatures were repeated. The period of 72h and 41 C with and without NaCl saturated solution was the most adequate for the lot classification in distint vigor levels.

Vermiculita como substrato para o teste de germinação de sementes de barbatimão

The objective of this research was to evaluate the use of vermiculite as a substrate for the germination test of 'barbatimao' seeds and to establish what would be the best granulometry and the best moisture intensity to germinate 'barbatimao' seeds. Four replications of 50 seeds were previously scarified with H(2)SO(4) for 60 minutes. Afterwards, the following germination substrates were evaluated: paper rolls moistened with water equivalent to 2.5 times the weight of the dry paper (control); micron, super thin, thin and average sized vermiculite moistened with 0.5, 1.0, 1.5 and 2.0 times the weight of the dry paper. The germination temperature was 30 C. The percentage of normal seedlings was obtained seven days after sowing (first count) and, then, weekly (up to 28 days). Average time and relative distribution of germination were calculated. It was concluded that the germination of 'barbatimao' seeds can be carried out with either fine vermiculite moistened with water equivalent to 2.0 times the weight of the dry paper or average sized substrate moistened with water equivalent to 0.5 to 2.0 times the weight of dry paper. These treatments resulted in higher and faster germination (21 days), similarly to the paper roll method.

Aplicacao do teste de qui-quadrado na verificacao da variacao de leituras densitometricas

The densitometrical interpretation is a technical resource that removes both the subjectivity of conventional interpretation and the high operational cost of automatic interpretation. Meanwhile, the densitometric lecture presents variability and this work has the objective of examinating, through Chi-square test, if there exists significative differences of cone overture of the densitometer as to the filter used. The results were the following: the variation that happened in this densitometric lecture, when different cone overture and filter were used, have not invalidated the values that were obtained; the extreme values variations have to be used with attention, so will not be overstep of values among the different elements of soil covering have to be used discerniment to classify this values; the study was in consonance with other authors. -from English summary

Caracterização silvicultural, botânica e avaliação da variabilidade genética por meio do marcador molecular RAPD em um teste de progênies de Eucalyptus urophylla S. T. Blake

Molecular markers have recently been incorporated into genetic improvement programs. They are already considered as powerful tools with several different uses, for instance the monitoring of genetic variability in tree populations. The main objectives of this study were to evaluate genetic variability in Eucalyptus urophylla progenies and together with silvicultural and botanical information, provide assistance to the improvement program. The Eucalypts population is located at the Experimental Forestry Sciences Station, Anhembi, SP, which belongs to the College of Agriculture Luiz de Queiroz. Sixty-nine progenies were analysed representing one individual by family in open pollinated Eucalyptus urophylla trees. The RAPD technique allowed the identification of 72 loci that were analysed using Jaccard's Coefficient generating a genetic similarity matrix to permit estimation of genetic distances. The results obtained showed genetic distance between individuals of 0.40 with 12 groups of genetic variability using a standardised distance of 40%. The progenies showed different bark patterns, allowing the establishment of bark groups. The groups formed based on genetic distances obtained using DNA analysis did not correspond to those based on bark pattern. Genetic selection was simulated in which silvicultural and genetic variability data were linked, thus avoiding excessive variability losses. The simulation of controlled crossings allowed the maximum genetic difference to be obtained linked with height and individual bark roughness.

Prevalência de reagentes ao teste de tuberculinização no rebanho bovino leiteiro da região de São Carlos - SP

Tuberculosis (TB), an infectious disease readily transmitted between animals and humans, is an great threat to public and animal health a like and has been declared an international emergency. According to the WHO, animal TB is a source of much concern, especially in the poorer countries where there is little awareness of the problem. Thus, improvements in veterinary health are essential, with regard to infection by Mycobacterium bovis, particularly in areas where the public is at risk. The prevalence of infected animals in Brazil is about 1%, whereas, in the dairy cattle region of São Carlos, the average proportion of positive tests was found to be 3. 1% from 1987 to 1996. The current research was carried out to investigate the prevalence, in the region, of dairy cattle reacting positively to the tuberculin test, from 1997 to the first half of 2001. The results were obtained by searching through the data collected by the Federal Inspection Authority, and they indicated an average prevalence of 1.3% over the period, similar to the official national average. It was concluded that bovine TB continues to be present in the region, posing a potential threat of infection to the human population.

Comparação, em mulheres inférteis, de teste de avaliação psicológica com a análise psicanalítica clássica

This study aims to compare a psychological evaluation test to classical psychoanalysis in infertile women. Two hundred women were submitted to the Psychological Evaluation Test (PET). The sum of the scores for the responses ranged from 15 to 60 points, with scores ≥ 30 points being defined as psycho-emotional maladjustment (cut-off point: median + 25%). For comparison, a psychologist submitted the patients to a psychological examination simultaneously, who was unaware of the PET results. From the 200 patients, 66 (33%) presented a test with ≥ 30 points (psycho-emotional maladjustment) and 134 (67%) a test with < 30 points (normal). Upon psychological examination, 105 (52.5%) presented an abnormal evaluation and 95 (47.5%) a normal evaluation. For the PET, statistical analysis showed 82% efficiency, 62% sensitivity, 98% positive predictive value, 99% specificity, 70% negative predictive value, likelihood ratio for a positive test result 62, and likelihood ratio for negative test result 0.38. The PET proved to be a useful clinical instrument, being of help for the selection of patients with psychological needs induced by infertility.

Acurácia do teste de escada utilizando o consumo máximo de oxigênio como padrão-ouro

Objective: To determine the accuracy of the variables related to the fixed-height stair-climbing test (SCT) using maximal oxygen uptake (V̇O 2 max) as the gold standard. Methods: The SCT was performed on a staircase consisting of 6 flights (72 steps; 12.16 m total height), with verbal encouragement, in 51 patients. Stair-climbing time was measured, the variables 'work' and 'power' also being calculated. The V̇O2 max was measured using ergospirometry according to the Balke protocol. We calculated the Pearson linear correlation (r), as well as the values of p, between the SCT variables and V̇O2 max. To determine accuracy, the V̇O 2 max cut-off point was set at 25 mL/kg/min, and individuals were classified as normal or altered. The cut-off points for the SCT variables were determined using the receiver operating characteristic curve. The Kappa statistic (k) was used in order to assess concordance. Results: The following values were obtained for the variable 'time': cut-off point = 40 s; mean = 41 ± 15.5 s; r = -0.707; p < 0.005; specificity = 89%; sensibility = 83%; accuracy = 86%; and k = 0.724. For 'power', the values obtained were as follows: cut-off point = 200 w; mean = 222.3 ± 95.2 w; r = 0.515; p < 0.005; specificity = 67%; sensibility= 75%; accuracy = 71%; and k = 0.414. Since the correlation between the variable 'work' and V̇O2 max was not significant, that variable was discarded. Conclusion: Of the SCT variables tested, using V̇O2 max as the gold standard, the variable 'time' was the most accurate.

Atividades séricas da aspartato aminotransferase, creatina quinase e lactato desidrogenase de eqüinos submetidos ao teste padrão de exercício progressive em esteira

The aim of this study was to determine the serum activities of enzymes aspartate aminotransferase, creatine kinase and lactate dehydrogenase in Arabian horses submitted to exercise on high-speed equine treadmill. Eleven mature Arabian horse were training and submitted to Standard Incremental Exercise Test on high-speed equine treadmill. Venous blood samples were taken before exercise, immediately and 30 min, 60min, 3h, 6h, 24h, 3 days and 5 days after exercise. The serum activity aspartate aminotransferase, creatine kinase and lactate dehydrogenase were determined. The serum activies of AST, CK and LDH increase immediately and returned to baseline value 30 minutes after exercise. The AST enzyme activity increased at 12 hours and 24 hours, CK at 3 hours and 6 hours, and LDH at 24 hours after Standard Incremental Exercise Test.

Aplicação da espirometria durante teste padrão de exercício progressivo em esteira para avaliação da troca gasosa respiratória de equinos da raça árabe

The current study evaluated equine gas exchange responses through spirometry, by measuring oxygen uptake (VO2), carbon dioxide production (VCO2), respiratory exchange ratio (R) and maximum oxygen uptake (VO2max) of Arabian horses during a standard incremental exercise test performed on a high-speed treadmill. Six clinically healthy Arabian horses were submitted to a standard incremental exercise test, performed on a high-speed treadmill at a 6% slope, and initial speed of 1,8 m.s-1 for 5 minutes, then 4,0 m.s-1 for 3 minutes, 6,0 m.s-1 for 2 minutes and 8,0 m.s-1, 9,0 m.s-1, 10,0 m.s-1 and 11,0 m.s-1 for one minute for each of these speed. The end of the exercise test was defined as the point in which the horse was no longer able to keep pace with the treadmill. Gas exchange was measured through respiratory analyses horse mask on the last 10 seconds at the end of each speed transition and at 1, 2 and 3 minutes after the end of the exercise, defined as experiment moments. During exercise, it was noticed an increase on both VO2 and VCO2 with linear relationship between exercise and speed. Arabian horses VO2max was 114,9 mL.kg-1.min-1. The respiratory exchange ratio increased over 1,0 by the speed of 9,0 m.s-1, indicating the preponderance of the anaerobic metabolism, and remains at a high level on the post-exercise period.

Variação genética, interação genótipo solo e ganhos na seleção em teste de progěnies de Corymbia citriodora Hook em Luiz Antonio, São Paulo

The aim of this study was to investigate the genetic variation, the genotype × soil interaction and the selection among and within Corymbia citriodora progenies in three different kinds of soils (Red Latossol, Quartz Sand and Purple Latossol), which occur in the Luiz Antônio Experimental Station, São Paulo State, Brazil. The progeny test was established 1983, using 56 open-pollinated families of C. citriodora. Twenty fve years after planting the following traits were measured: height, diameter at breast height (Dbh), stem form and survival. Best growth occurred in Purple Latossol. Significant differences among progenies were detected for most traits in all sites, suggesting the possibility of improvement by selection. In the analysis with sites, Significant differences among locals, progenies and genotypes × soil interaction were detected, confiming that the tested material has sufficient genetic variation to be explored by selection in all sites. The analysis of genotype × soil interaction indicates that growth traits present single interaction and the same progenies can be selected in each site. On the order hand, genotype × soil interaction for stem form and survival was complex; and specifc progenies need to be selected for each kind of soil. The population, due to its high genetic variation and strong genetic control of traits, permits to obtain considerable genetic gains by selection among and within progenies.

Avaliação do vigor de sementes de rúcula pelo teste de lixiviação de potássio

The objective of this study was to evaluate methodologies for the potassium leaching test and to verify its sensitivity for identifying different levels of vigor of arugula seed lots. Five seed lots each of Rucula Cultivada and Rucula Gigante were used. Standard germination, first count of germination, seedling emergence and variations of the potassium leaching test (50 or 100 seeds imbibed in 50 mL or 75 mL in water; at 25 °C and 30 °C; for 0.5 h, 1 h, 1.5 h, 2 h, 2.5 h, 3, 4 and 5 hours) were done. It was observed that the period seeds need to be soaked can be reduced to 2 hours and the water volume can be reduced to 50 mL. The utilization of 50 seeds showed a smaller variation coefficient and the best temperature was 30 °C. It can be concluded that the potassium leaching test for arugula seeds can be run using 50 seeds in 50 mL of water for 2 hours at 30 °C.
