Uso de estrados de madeira em diferentes níveis de sombreamento na avaliação do crescimento e desenvolvimento de plantas de capim-annoni.

O capim-annoni (Eragrostis plana Ness) é uma planta fibrosa que contém poucos nutrientes e que causa muitos prejuízos ao produtor. Quando submetido a níveis de sombreamento ele tende a mudar o seu crescimento. O presente trabalho teve como objetivo avaliar o crescimento e o desenvolvimento das plantas de annoni em diferentes níveis de sombreamento.Editora técnica Claudia Cristina Gulias Gomes

Caracterização da composição florística em uma área silvipastoril na região da Campanha.

O objetivo desse trabalho é identificar as principais espécies que ocorrem em uma área silvipastoril de 34 hectares, submetida aos seguintes tratamentos: 3 níveis de luminosidade sobre a pastagem (pleno sol; 800 e 400 árvores/ha) e 2 manejos de recuperação da pastagem degradada pelo capim annoni (intensivo ou pastagem melhorada com azevém anual+cornichão cv. São Gabriel+trevo-vermelho E116 e conservador ou uso da tecnologia Campo Limpo).Editora técnica Claudia Cristina Gulias Gomes

Parasitos do matrinxã Brycon amazonicus Spix & Agassiz, 1829 (Characidae: Bryconinae) na Amazônia Central.

Neste capítulo descrevem-se os parasitos de matrinxã Brycon amazonicus cultivado em diferentes modalidades na Amazônia Central. Estudos demonstram que com a intensificação do cultivo deste peixe os problemas com as infecções parasitárias também podem mostrar incremento, devido às condições sanitárias, transporte e manejo inadequados. O transporte de peixes é uma maneira rápida de propagação de doenças, quando os cuidados com profilaxia e quarentena não são mantidos na piscigranja. Nestes estabelecimentos de cultivo, os estudos de parasitofauna podem auxiliar no controle e proliferação dos parasitos, evitando assim perdas econômicas significativas para o produtor.bitstream/item/211044/1/CPAF-AP-Parasitos-de-matrinxa.pd

Predictors of enhancing human physical attractiveness: Data from 93 countries

People across the world and throughout history have gone to great lengths to enhance their physical appearance. Evolutionary psychologists and ethologists have largely attempted to explain this phenomenon via mating preferences and strategies. Here, we test one of the most popular evolutionary hypotheses for beauty-enhancing behaviors, drawn from mating market and parasite stress perspectives, in a large cross-cultural sample. We also test hypotheses drawn from other influential and non-mutually exclusive theoretical frameworks, from biosocial role theory to a cultural media perspective. Survey data from 93,158 human participants across 93 countries provide evidence that behaviors such as applying makeup or using other cosmetics, hair grooming, clothing style, caring for body hygiene, and exercising or following a specific diet for the specific purpose of improving one physical attractiveness, are universal. Indeed, 99% of participants reported spending >10 min a day performing beauty-enhancing behaviors. The results largely support evolutionary hypotheses: more time was spent enhancing beauty by women (almost 4 h a day, on average) than by men (3.6 h a day), by the youngest participants (and contrary to predictions, also the oldest), by those with a relatively more severe history of infectious diseases, and by participants currently dating compared to those in established relationships. The strongest predictor of attractiveness-enhancing behaviors was social media usage. Other predictors, in order of effect size, included adhering to traditional gender roles, residing in countries with less gender equality, considering oneself as highly attractive or, conversely, highly unattractive, TV watching time, higher socioeconomic status, right-wing political beliefs, a lower level of education, and personal individualistic attitudes. This study provides novel insight into universal beauty-enhancing behaviors by unifying evolutionary theory with several other complementary perspectives.info:eu-repo/semantics/publishedVersio

Differential cross sections for electron impact excitation of the electronic bands of phenol

We report results from a joint theoretical and experimental investigation into electron scattering from the important organic species phenol (C6H5OH). Specifically, differential cross sections (DCSs) have been measured and calculated for the electron-impact excitation of the electronic states of C6H5OH. The measurements were carried out at energies in the range 15–40 eV, and for scattered-electron angles between 10° and 90°. The energy resolution of those experiments was typically ∼80 meV. Corresponding Schwinger multichannel method with pseudo-potentials calculations, with and without Born-closure, were also performed for a sub-set of the excited electronic-states that were accessed in the measurements. Those calculations were conducted at the static exchange plus polarisation (SEP)-level using a minimum orbital basis for single configuration interaction (MOBSCI) approach. Agreement between the measured and calculated DCSs was typically fair, although to obtain quantitative accord, the theory would need to incorporate even more channels into the MOBSCI
