Collection of Fáfia [Pfaffia glomerata (Spreng.) Pedersen] in Northwestern State of Paraná - Brazil

Interviews were conducted with fáfia (Pfaffia glomerata (Spreng.) Pedersen) collectors from the municipal districts of Querência do Norte and Porto Rico, where enterprises and buyers of this plant are concentrated. The results allowed us to conclude that both the adults and children make collection. Each adult collects from 50 to 150 kg of roots/day, depending on the collection area, for about 8 months/year. Collections mostly occur all over the year, but the activity becomes more intense from May to August. All families are not exclusively dedicated to fáfia collection and also develop other rural activities. They have been collecting fáfia for 2 to 13 years, indicating that an intensive exploitation has been present in the region for over a decade. During collection, no plant part is used for replanting the species. The roots are commercialised by regional buyers. The price of the roots varies from US $ 0.07 to US $ 0.13/kg and average gain is about US $ 2,055/family/year, representing a considerable profit for the collectors.

Resistência à penetração de um solo em recuperação sob sistemas agrosilvopastoris

In the Research and Teaching Farm of the State University of São Paulo (UNESP) - Campus of Ilha Solteira, located in Selviria, in Mato Grosso do Sul State, a study was conducted with the objective of investigating the resistance to penetration of a highly degraded soil due to construction of a Hydroelectric Power Plant. The experimental design was a completely randomized, with five treatments and five replications. The treatments were constituted of the following uses and managements: area in advanced state of degradation; area under regeneration cultivated 13 years with Pinus; area under regeneration cultivated 11 years with green manure and pasture; degraded area with natural regeneration; and area with natural vegetation (savanna). The system where the area was under regeneration with Pinus cultivation and the niches with natural regeneration were the closest to natural condition (savanna). Except for the natural area (savanna), all others presented a higher resistance to penetration in the layer of 0.20-0.40 m, which represents serious limitations for growth of plant roots.

Efeito do desbaste seletivo sobre a divergência genética em progênies de Pinus caribaea Morelet var. bahamensis

The objective of this work was to study the effect of selective thinning on the genetic divergence in progenies of Pinus caribaea var. bahamensis, aiming to identify the most productive and divergent progenies for the use of improvement program. The test of progenies containing 119 progenies and two commercial controls were planted in March 1990, using 11 × 11 square lattice design, sextuple, partially balanced, disposed in lineal plots with six trees in the spacing of 3,0 × 3,0m. 13 years after planting thinning was realized (selection for DBH), with 50% selection intensity based on Multi-effect index, leaving three trees per plot in all the experiment. The evaluations were done at four situations: A (before the thinning); B (thinned trees); C (remaining trees after thinning) and D (one year after thinning). The analyzed traits were: height, diameter at breast height (DBH), volume, form of stem and wood density. The genetic divergence among the progenies was studied with aid of the canonical variables and of clustering of Tocher method, using the generalized distance matrix of Mahalanobis (D2) as estimate of the genetic similarity. The progenies were grouped in four groups in situation A, fourteen in the situation B, two in the situation C and three in the situation D. The selective thinning of the trees within of the progenies caused a change in the genetic divergence among the progenies, genetically homogenizing the progenies, as demonstrated by the generalized distances of Mahalanobis, clustering of Tocher' and canonical variables methods. The thinning made possible a high uniformity in respect to the relative contribution of the traits for the total genetic divergence. The techniques of clustering were efficient to identify groups of divergent progenies for the use hybridization and little divergent progenies for the use in backcross program.

Efeito do desbaste seletivo nas estimativas de parâmetros genéticos em progénies de Pinus caribaea Morelet var. hondurensis

The objective of this work was to study the effect of selective thinning on the estimates of genetic parameters in progenies of Pinus caribaea var. hondurensis. The progeny test was installed in June 1986, following a 10 × 10, triple square lattice design, containing ten trees in linear plots in 3.0 × 3.0m spacing. Twelve years after the planting, a selective thinning based on Multi-effect index (selection for DBH) was performed, leaving six trees per plot. The assessments were done in four situations: A (before thinning); B (among thinned trees); C (among remnant trees at 13 years of age) and D (two years after the thinning). The following traits were analyzed: total height (H), diameter at breast height (DBH), volume (VOL), stem form (FOR), foxtail (FT), wood density at 1.3 m (WD1) and wood density at the half height (WD2). The thinning led to increase in the estimates of variability among progenies for VOL and decrease for ALT and DBH. There was a high and positive genetic correlation among the growth traits, mainly between DBH and VOL. The latter remained unchanged after thinning. The narrow-sense heritabilities at the individual level, showed a slight increase while at the family mean level had a reduction with the thinning. The estimates of breeding values increased with the thinning. This may lead to an easier identification of the best progenies in further selection.

Overjet and overbite analysis during the eruption of the upper permanent incisors.

ABSTRACT The purpose of this study was to analyze the overjet and overbite behavior during eruption of the upper permanent incisors. Fourth-eight plaster casts of 16 patients from ages 6-13 years were appraised longitudinally. It was found that the overjet remains constant, starting at the eruption of the upper permanent central incisors until eruption of the upper permanent canine teeth, while the overbite increases after eruption of the upper permanent lateral incisors and remains constant with the eruption of the canine teeth.

Sérgio Buarque de Holanda na USP

The main purpose of the article is to describe and to analyse Sérgio Buarque de Holanda's trajectory in Universidade de São Paulo (USP). At USP, he could dedicate himself entirely in what he liked to do: to research. There, Sérgio Buarque de Holanda formed a researchers' group and he changed the teaching routes in History course, which formed only Elementary and High School teachers. He idealized and founded the Instituto de Estudos Brasileiros (Brazilian Studies Intitute), a multi-disciplinary institution responsible for important researches included the theme Brasil. In this Institute (IEB), he formed a ample archive and a important library. In 1969, the 13-years-job at USP finished itself in a careworm process, when he asked for his retirement in sympathy with other retired professors compulsorily by AI-5.

A influência da dança na percepção de estruturas rítmicas monotônicas em adolescentes surdos

Dance activities were administered to a group of deaf adolescents via visual and auditory stimuli in order to improve their perceptions of monotonic rhythmic structures. Status of psychomotor development was also assessed before and after participation in the program. Twenty deaf adolescents (ages between 12 and 13 years) were divided into two groups, experimental (EG) and control (CG). Before and after participating in the program for 26 weeks, participants were evaluated in rhythmical tasks adapted from the classical test of M. Stambak. The tasks included the perception of drum beats, actually viewed hit movements, or heard via a sound amplifier. Psychomotor tests were administered only to the EG. The period of practice with dance activities changed the individuals' performance in the monotonic rhythmic test. Also, the success rate improved in both, visual and auditory input tasks. Individuals in the CG showed no changes in performance. For the EG, in the post-test, the status of psychomotor development was six months below the target age of the tests (i.e., 11 years). Findings suggested that dance activities can change deaf individuals' auditory perception of rhythmic structures. Participation in such a program can also positively affect psychomotor development. © FTCD/FIP-MOC.

Morphometric analysis of treatment effects of the Balters bionator in growing Class II patients

Objective: To investigate the effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Materials and Methods: Thirty-one Class II patients (17 male and 14 female) were treated with the Balters bionator (bionator group). Mean age at the start of treatment (T0) was 10.3 years, while it was 13 years at the end of treatment (T1). Mean treatment time was 2 years and 2 months. The control group consisted of 22 subjects (14 male and 8 female) with untreated Class II malocclusion. Mean age at T0 was 10.2 years, while it was 12.2 years at T1. The observation period lasted 2 years on average. TPS analysis evaluated statistical (permutation tests) differences in the craniofacial shape and size between the bionator and control groups. Results: Through TPS analysis (deformation grids) the bionator group showed significant shape changes in the mandible that could be described as a mandibular forward and downward displacement. The control group showed no statistically significant differences in the correction of Class II malocclusion. Conclusions: Bionator appliance is able to induce significant mandibular shape changes that lead to the correction of Class II dentoskeletal disharmony. © 2013 by The EH Angle Education and Research Foundation, Inc.

Behavioral and Antinociceptive Effects of Alfentanil, Butorphanol, and Flunixin in Horses

To determine the behavioral and antinociceptive effects of narcotic and non-narcotic analgesics administered by intravenous injection in horses, 10 thoroughbred mares weighing between 450 and 550 kg and ranging in age from 8 to 13 years old were analyzed. The effects of alfentanil, butorphanol, flunixin, and saline solution on the general activity of the horses were investigated by measuring spontaneous locomotor activity (SLA) and head height (HH) in two behavior stalls. The antinociceptive effects of alfentanil (0.02 mg kg-1), butorphanol (0.1 mg kg-1), flunixin meglumine (0.5 mg kg-1), and saline were determined by measuring skin twitch reflex latency (STRL) after thermal cutaneous nociceptive stimulation. A paired Student t-test was used to compare SLA and HH between the groups of horses receiving different doses of the same drug at various time points. The Tukey test was used to compare the antinociceptive effect of the treatments. Differences were considered significant when P value was <.05. Horses treated with opioid analgesics demonstrated excitation, as shown by a significant increase in SLA at all doses tested and by neighing and demonstrating attentive attitudes with movement of the ears, stereotypical walking, and ataxia in most of the animals. HH was elevated only in animals treated with alfentanil. Antinociception was observed at 5 and 30 minutes after administration of alfentanil and butorphanol, respectively. Increased SLA was observed at 30 and 90 minutes after administration of alfentanil and butorphanol, respectively. We observed no effect on antinociception in horses given flunixin. In conclusion, this study suggests that alfentanil has a faster onset and a shorter duration than butorphanol; however, both drugs are able to stimulate the central nervous system. © 2013 Elsevier Inc.
