Protandry and female size-fecundity variation in the tropical butterfly Brassolis sophorae

Protandry (the emergence of males before fe males) is currently explained either as a mating strategy to maximize number of matings in the males, or a way to minimize pre-reproductive mortality in females, Models of protandry have generally ignored variation in female quality (reproductive potential). We recorded the sex ratio, female body mass, wing length and potential fecundity (number and mass of eggs) of the tropical butterfly Brassolis sophorae through the emergence period. Temporal variation in female size and fecundity correlated with male potential for acquiring mates. Females from the end of the emergence period showed lower fecundity and size. Males emerging before and close to the median date of the female emergence period had greater mating opportunities. Males emerging either very early or late were penalized by few mating opportunities, or by encounters with small: low-quality females, respectively.

Intrageneric karyotypic divergence in Scythrophrys and new insights into the relationship with Paratelmatobius (Anura, Leptodactylidae)

Three populations of Scythrophrys from Brazil were studied cytogenetically. The karyotype found in Piraquara (Parana State) and Sao Bento do Sul (Santa Catarina State) (karyotype 1) differed from that of Rancho Queimado (Santa Catarina State) (karyotype 11) in NOR location and in the occurrence of some C-bands. In karyotype I, pair 5 contained NOR-bearing chromosomes, while in karyotype 11 the NOR occurred in pair 10. This difference probably accounts for the inverted classification of pairs 5 and 6 in these karyotypes, which appear to be homologous, as suggested by the presence of heterochromatic markers. These karyotypes also differed in the size of the non-centromeric C-bands in pairs 1 and 8. Comparison of the Scythrophrys karyotypes with those of the related genus Paratelmatobius revealed several similarities, especially between karyotype 11 of Scythrophrys and that of P. poecilogaster. Both karyotypes had a NOR in pair 10, so it was inferred to be present also in the common ancestor for these genera. The non-centromeric C-bands in pairs 7, 10, and in pair 5 of karyotype I and pair 6 of karyotype II of Scythrophrys are characters exclusively found in this genus.

Programmed cell death in salivary glands of Drosophila arizonae and Drosophila mulleri

Programmed cell death (PCD) in insect metamorphosis assumes a great diversity of morphology and controlling processes that are still not well understood. With the objective of obtaining information about the PCD process, salivary glands of Drosophila arizonae and D. mulleri were studied during larval-pupal development. From the results, it can be concluded that the type of the PCD that occurs in these organs is morphologically typical of apoptosis (formation of apoptotic nuclei, followed by fragmentation into apoptotic bodies). Histolysis happens in both species, between 22 and 23 h after pupation. There were no significant differences between the species studied. Apoptosis does not occur simultaneously in all cells. Cytoplasmic acid phosphatase activity gradually increases during development, suggesting the existence of acid phosphatases that are only expressed during the apoptotic stage. Twenty hours after pupation, salivary glands already show biochemical alterations relative to nuclear permeability such as acidification, possibly due to the fusion of lysosomes with the nucleus a few hours before apoptosis. Autophagy seems to act together with apoptosis and has a secondary role in cell death. ©FUNPEC-RP.

Projeto de um módulo condicionador de sinais a ser implementado no satélite universitário ITASAT

The Brazilian Environmental Data Collection System (Sistema Brasileiro de Coleta de Dados Ambientais - SBCDA) has been providing reliable information regarding the monitoring of the Brazil environment to INPE (Instituto Nacional de Pesquisas Espaciais) and many Non-governmental organizations (NGO). This system is composed of a large number of Data Collection Plataforms (DCP), in charge of sending local data signals to satellites. Then the satellites automatically redirect each signal to reception centers located at INPE. Nowadays the SBCDA has been operating under the control of three satellites. It is important to mention that two of these satellites have already expired their life span around ten years ago. A strategy to keep the SBCDA operational is to develop a low cost satellite that involves Brazilian Universities and Public Institutions. This graduation work aims to design and simulate a signal conditioning module that enables the collection of a satellite status data, and then sending it to an onboard computer

A empregabilidade das pessoas com deficiência: uma análise da inclusão social no mercado de trabalho do município de Bauru, SP

Based on the precepts of social inclusion, this research objected to examine the employment of people with disability(PWD), according to decree nº 3.298 which establishes hiring quotas for PWD in companies with 100 or moreemployees. Interviews were made with employees of HR departments in 12 different companies located in the westside of the state of São Paulo, based on a structured script. All the interviews were transcripted and gathered inanalysis categories. The results showed that one third of private companies comply with the regulation foremployment of PWD. Corporate policies prioritize hiring of people whose disabilities do not demand structuralmodifications in the work environment, or those whose disabilities represent a positive aspect for production lines.The majority of the interviewed understand disabilities as an individual phenomenon. Although they have talkedabout equal rights for everyone, the majority of them do not present a consistent speech based on the precepts ofsocial inclusion, for they fail to promote actions for supporting the population with disabilities and expecting thatthose with disabilities are the ones responsible to adjust themselves to all imposed conditions.

A natação e o processo de inclusão das pessoas com deficiência nas academias de Bauru

The swimming is one of the most suitable activities for the stimulation of People with Desabilitie (PWD), we want it isfor the freedom of corporal action for those that possess motive limitation, as well as, for the discovery need, corporal adaptation inthe aquatic way. This way, in the academies that develop this activity it is waited we find PWD inserted in the classes. The objective ofthis study was to verify the inclusion process it is happening in the academies of swimming of the city of Bauru-SP. A field research wasdeveloped, of qualitative character and of exploratory stamp, where they were contacted the academies that taught swimming initially andthose that they were disposed to participate in the research, in a total of 10 academies. We verified that, of a total of 3105 people enrolledin the swimming classes in the academies 19 they were only PWD, in other words, 0,61%. Although the inclusion process is found in theswimming academies, this is very limited.

Importância da avaliação do desempenho aquático das pessoas com deficiência inseridas em aulas de natação para iniciação do treinamento paralímpico

Este trabalho aborda a natação para a pessoa com deficiência (PCD), tendo como objetivo verificar o nível de desempenho aquático de participantes do projeto de ensino de natação adaptada. Destacamos o intuito de avaliar a perspectiva de início de um treinamento paralímpico em natação. Foram analisados 14 usuá- rios da Sorri-Bauru, vinculados a um programa de iniciação, quanto ao seu nível de desempenho na água. Verificamos que a grande maioria ainda encontra-se em fase inicial da aprendizagem dos estilos, onde a respiração e a autonomia no meio líquido ainda necessitam ser amplamente dominadas. Porém, a partir dos resultados é possível propor o início do processo de treinamento criando um vínculo entre a PCD e o professor/técnico e que sejam respeitadas as limitações e potencialidades dos participantes.

A inclusão da natação na vida da pessoa com deficiência: uma análise a partir da teoria ecológica do desenvolvimento

The objective of thisstudy was to verify, using the Ecological Development Theory (EDT), as the practice and swimming learning for People With Disabilities (PWD) causes changes to both the practitioner and in other environments experienced by it as well as the other environments influence the learning to swim. The study included 16 PWD, students linked university extension project, Department of Physical Education of UNESP Bauru, taught by coordinators LAPEF, which aims to includes wimming in the PWD ofevery day life, students linked to an institution of Bauru-SP, three employees of the institution and two swimming project teachers.Interviews with the families of the students were made, with the institution s employees, with the project teachers and analyze thes wimming lessons applied in the project for one semester. Based on the results we can say that the practice and learnings wimming for PWD causes changes to both the practitioner and for other environments experienced by her (home, institution) and also, what other environments experienced by PWD influence in practice and process of learning to swim. Using the terminology of EDT, we conclude that theme so system (home activities institution) influences in the microsystem (swimming lessons) and the microsystem influences the mesosystem, so the activity was significant and temporal persistence influencing the development of PCD.

Fhos encodes a Drosophila Formin-Like Protein participating in autophagic programmed cell death

Larval tissues undergo programmed cell death (PCD) during Drosophila metamorphosis. PCD is triggered in a stage and tissue-specific fashion in response to ecdysone pulses. The understanding of how ecdysone induces the stage and tissue-specificity of cell death remains obscure. Several steroid-regulated primary response genes have been shown to act as key regulators of cellular responses to ecdysone by inducing a cascade of transcriptional regulation of late responsive genes. In this article, the authors identify Fhos as a gene that is required for Drosophila larval salivary gland destruction. Animals with a P-element mutation in Fhos possess persistent larval salivary glands, and precise excisions of this P-element insertion resulted in reversion of this salivary gland mutant phenotype. Fhos encodes the Drosophila homolog of mammalian Formin Fhos. Fhos is differentially transcribed during development and responds to ecdysone in a method that is similar to other cell death genes. Similarly to what has been shown for its mammalian counterpart, FHOS protein is translocated to the nucleus at later stages of cell death. Fhos mutants posses disrupted actin cytoskeleton dynamics in persistent salivary glands. Together, our data indicate that Fhos is a new ecdysone-regulated gene that is crucial for changes in the actin cytoskeleton during salivary gland elimination in Drosophila. genesis 50:672684, 2012.
