25. Architecture of tree species of different strata developing in environments with the same light intensity in a semideciduous forest in southern Brazil
We aimed to answer the following questions related to the architecture of individuals 0.5-3.0 m in height belonging to understory or canopy/emergent layer tree species: "Is there a difference between individuals belonging to different strata developing in environments with the same light intensity, in terms of their architecture?"; and "Given the same light

26. Effects of cellular growth on fatigue life of directionally solidified hypoeutectic Al-Fe Alloys
Al-Fe hypoeutectic alloys are a family of casting alloys characterized by cell growth, low cost and appreciable formability. It is well known that fatigue strength is a requirement of prime importance considering the nature of load typically observed during operations involving the risers used in oil extraction. The aim of this study is to examine the influe

27. The columnar to equiaxed transition of horizontal unsteady-state directionally solidified Al-Si alloys
Experiments were conducted to investigate the influence of thermal parameters on the columnar to equiaxed transition during the horizontal unsteady-state directional solidification of Al-Si alloys. The parameters analyzed include the heat transfer coefficients, growth rates, cooling rates, temperature gradients and composition. A combined theoretical and exp

28. The Wits appraisal among a Nigerian sub-population: an assessment of dental base geometric factors
The Wits appraisal is a common linear cephalometric analytic tool established by Jacobson. It has been reported to be superior to angular cephalometric measures as it is not dependent on pericranial structures and their variations both during growth and orthodontic treatment. AIM: To obtain reference values for the Wits appraisal among Nigerians and assess t

29. Longitudinal study of mandibular behavior in Class I subjects with vertical and horizontal growth
OBJETIVO: avaliar as possíveis diferenças no comportamento mandibular em indivíduos Classe I com crescimento vertical e horizontal. MÉTODOS: a amostra desse estudo consistiu de 20 indivíduos Classe I não tratados, sendo o grupo 1 composto por 10 indivíduos com padrão de crescimento vertical e o grupo 2 por 10 indivíduos com padrão de crescimento ho

30. Resistance exercise improves hippocampus-dependent memory
It has been demonstrated that resistance exercise improves cognitive functions in humans. Thus, an animal model that mimics this phenomenon can be an important tool for studying the underlying neurophysiological mechanisms. Here, we tested if an animal model for resistance exercise was able to improve the performance in a hippocampus-dependent memory task. I

31. Influence of treatment with and without extractions on the growth pattern of dolichofacial patients
OBJETIVO: o objetivo desse estudo retrospectivo foi comparar, por meio de telerradiografias, as alterações no padrão de crescimento facial decorrentes do tratamento sem e com extrações dos quatro primeiros pré-molares em indivíduos dolicofaciais. MÉTODOS: os grupos 1 e 2 foram constituídos, cada um, por 23 pacientes dolicofaciais com má oclusão Cl

32. Orthopedic treatment of Class III malocclusion with rapid maxillary expansion combined with a face mask: a cephalometric assessment of craniofacial growth patterns
OBJECTIVE: The aim of this prospective study was to assess potential changes in the cephalometric craniofacial growth pattern of 17 children presenting Angle Class III malocclusion treated with a Haas-type expander combined with a face mask. METHODS: Lateral cephalometric radiographs were taken at beginning (T1) and immediately after removal of the appliance

33. Influence of anatomical barriers on maxillary incisor root resorption after orthodontic treatment with premolar extractions
INTRODUCTION: Apical root resorption is a frequent and occasionally critical problem in orthodontic patients undergoing induced tooth movement. One of the factors that might influence prognosis, especially in maxillary incisors, which most frequently present resorptions, are the so-called the anatomical barriers; that is, proximity of the buccal and palatal

34. Cephalometric evaluation of skeletal alterations induced by Herbst appliance during mixed dentition
OBJECTIVE: The present prospective clinical study was designed in order to evaluate horizontal and vertical skeletal alterations induced by the use of Herbst appliance in individuals with Class II, division 1 malocclusion during mixed dentition stage. METHODS: The sampling consisted of 15 pre-pubertal individuals (12 boys and 3 girls; initial age 9 years and

35. Enterobacteria isolation in ostrich eggs (Struthio Camelus)
This study was conducted to determine the presence of enterobacteria in the eggs of ostriches reared on a farm with a history of reproductive failure. Ninety samples from twenty eggs were submitted to bacteriological tests. The results showed Enterobacteria growth in 100% of the eggs. The microorganisms isolated were Hafnia alvei in 50% (10/20), Serratia spp

36. Vertical growth control during maxillary expansion using a bonded Hyrax appliance
INTRODUCTION: Rapid maxillary expansion (RME) for the treatment of maxillary deficiency and posterior crossbite may induce changes in the vertical dimension. Expanders with occlusal splints have been developed to minimize unwanted vertical effects. OBJECTIVE: This preliminary study used cephalometri radiographs to evaluate the vertical effects of RME using a
