Reproductive biology, including phenology, f ower biology, pollination, and the reproductive system in the bromeliad Aechmea distichantha were studied in an Araucaria forest in the state of Paraná. Phenology and reproduction in terricolous plants were followed in October 2006 and May - October of 2007. Flowering peaked from June to September and fruiting was from June to October. Flower anthesis lasted one day. Flowers were pollinated the most by the hummingbird Stephanoxis lal-andi and the most common butterf y visitor was Lychnuchoides ozias ozias. Nectar concentration declined during anthesis, while nectar volume was constant. Aechmea distichantha is self-compatible with 30-45% fruit formation in self-pollination tests. Sunlight inf uences reproduction: when controlling for bromeliad and inf orescence size, plants in sunlight produced more seeds per fruit than plants in the shade. Reproduction was also associated with inf orescence size when controlling for bromeliad size. T at is, larger inf orescences in similar sized plants produced more f owers and more seeds per fruit.

CFR-PEEK (carbon fiber reforced-poly ether ether ketone) has been demonstrated to be excellent substitute titanium in orthopedic applications and can be manufactured with many physical, mechanical, and surface properties, in several shapes. The aim of this study was to compare, using the three-dimensional finite element method, the stress distribution in the peri-implant support bone of distinct models composed of PEEK components and implants reinforced with 30% carbon fiber (30% CFR-PEEK) or titanium. In simulations with a perfect bonding between the bone and the implant, the 30% CFR-PEEK presented higher stress concentration in the implant neck and the adjacent bone, due to the decreased stiffness and higher deformation in relation to the titanium. However, 30% CFR-PEEK implants and components did not exhibit any advantages in relation to the stress distribution compared to the titanium implants and components. © 2010 Springer Science+Business Media, LLC.

During the months of October 2004 and June 2005, collections were made to identify the fish fauna associated with a culture of Perna perna mussel located in the district of Paulas, in the municipality of San Francisco do Sul, Santa Catarina State. It collected a total of 511 fish corresponding to seven species and six families (Blenniidae, Gobiidae, Labrisomidae, Serranidae, Gobiesocidae and Monacanthidae), the species Hypleurochilus fissicornis, Bathygobius soporator and Gobiesox strumosus being the most abundant. H. fissicornis was dominant in the samples and was present, along with G. strumusus, in all sampling months. B. soporator was not recorded in the month of October, and the remaining species occurred in two or three samplings, with the exception of the exotic specie Omobranchus punctatus, which occurred in a single sample (September 2005), corroborating its record in the area. The average values of biomass and abundance increased in the months near summer, with peak capture occurring in the month of January 2005. In the analysis of grouping by hand size, greater similarity was observed mainly in the hands sampled during the summer, which was observed with larger hand lengths. The cultivation of mussels creates a new substrate favorable to the occupation of several marine species by encouraging the growth and establishment of potentially competing, commercially important and/ or threatened species.

This retrospective study assessed the results of 71 patients with knee dislocations who underwent acute combined repair and reconstruction using Ligament Advancement Reinforcement System (LARS) artificial ligaments between June 1996 and May 2008 with a follow-up between two and eight years. The outcome measures used were the Lysholm score, the International Knee Documentation Committee form (IKDC 2000), the Tegner activity level score, the Meyers ratings, Telos stress radiography, range of motion and clinical knee stability testing. When comparing high- versus low-energy dislocations and knee dislocation (KD) II/III versus KD IV injuries, a better Lysholm score for the knee dislocation (KD) II/III group was found compared with the KD IV group. The subjective and objective findings from our study are satisfactory and comparable with the results of other studies of knee dislocations. Our findings suggest that with a mean follow-up of 54 months, acute combined repair and reconstruction with LARS ligaments is a valid alternative for treating knee dislocations. © 2010 Springer-Verlag Reference:.

Firearms in Brazil: Public Policies and Impacts on Auditory Health | Year: 2014
The book was developed based on the expertise of four research groups, three of them linked to the Universidade Estadual Paulista (UNESP): Studies on Hearing; Public Safety Observatory of UNESP; Research and Urban Management Organized Labor Group (GUTO); and Labor, Health and Society linked to the Tuiuti University. The groups mentioned above fit mainly into two major areas, Speech and Social Sciences, with a focus on the following research lines: hearing health and public safety. For this reason, the present work is multidisciplinary and includes current information, of scientific relevance, focused on the theme "firearms". This diversity has allowed the production of chapters that approach the audiological profile of militaries exposed to impact noise during their work activities, as well as the measurement of noise generated by firearms. Another situation that is worth mentioning is the recreational activity on private booth shots (as shooting clubs), where hearing protection is also required. It is also worth noting that the book discusses violence with firearms in contemporary Brazilian society. © 2014 by Nova Science Publishers, Inc. All rights reserved.
