Bate-papo sobre processos e threads

O material apresenta explicações e exemplos de processos e threads (tarefas). Destaca ainda a multitasking (capacidade do Sistema Operacional de ter mais de um processo em execução ao mesmo tempo), a estrutura interna de um Sistema Operacional, as interrupções síncronas e assíncronas, o gerenciamento de múltiplos processos (tarefas, ou tasks) e a técnica de multiprogramação. O material também cita e descreve o sistema operacional multiusuário; o multiprocessamento e as múltiplas threads (tarefas) em um mesmo processo.

Bate-papo sobre Chamadas de Sistema

O material apresenta as chamadas de sistema, ou system calls, que são rotinas de serviço oferecidas por um sistema operacional aos programas. Além de escalonar o uso do(s) processador(es) para a execução das instruções dos processos, o Sistema Operacional tem a função de prover serviços a esses processos. O material destaca ainda o código executado pelas chamadas de sistema que reside na memória; a portabilidade dos programas; e os tipos de chamadas de sistema nos sistemas operacionais Microsoft, Unix e Linux.

Ecological distribution of the shrimp Pleoticus muelleri (Bate, 1888) (Decapoda : Penaeoidea) in southeastern Brazil

The abundance and ecological distribution of the shrimp Pleoticus muelleri as a function of certain environmental factors were investigated from January 1998 through December 1999 in the region of Ubatuba, São Paulo, Brazil. The collections were made monthly in the bays of Ubatumirim (UBM), Ubatuba (UBA) and Mar Virado (MV). Each bay was divided into six sampling transects, four transects parallel to the shoreline and two near the rocky shores on the opposite side. We employed a commercial shrimp boat equipped with two double-rig nets. A total of 6252 shrimp were collected, including 3321 from MV, 1467 from UBM, and 1464 from UBA. Most of the shrimp were caught in the deeper, higher-salinity areas. The high abundance of P. muelleri observed in the southern part of the region studied was related to a sediments with a higher percentage of silt and clay. The numbers of P. muelleri were positively correlated with periods of cooler temperatures. Thus, temperature and the type of sediment were determinant factors in the distribution of P. muelleri in this region.

Letramento e Oralidade: Notas sobre Pontuação em um Bate-papo Virtual Infantil

Based on a heterogeneous concept of writing, this paper aims at analyzing ‘breaks’ in utterances of a virtual chat for writers between 8 and 12 years of age. The hypothesis is that the segmentation of an utterance in different lines in a short period of time characterizes the writing on the internet as nonconventional and relates it to the prosody and rhythm of the language not restricted to the phonic or graphic dimension of the verbal language.

Diel Variation in Abundance and Size of the South American Red Shrimp Pleoticus Muelleri (Spence Bate, 1888) (Decapoda, Solenoceridae) in the Ubatuba Region, Southeastern Brazil

Diel variation in the abundance and size of Pleoticus muelleri in the Ubatuba region was investigated during 2000. During each season of the year, sampling was conducted during the day and at night at 8 depths, from 5 to 40 m. The estimated number of shrimp was 955 individuals, 272 collected during the day and 683 at night. There was a difference in the abundance of P. muelleri between day and night (χ², p=2.33E-40). The abundance during the day and at night differed by season with the exception of the spring (χ², p=0.06). The abundance during both periods also differed by depth, except at 15 and 30 m, where it was not significant (χ², p=0.84 and 0.06, respectively). The shrimp caught at night were generally smaller than those caught during the day (Kolmogorov-Smirnov, p<0.01). Pleoticus muelleri juveniles were found primarily at night. This tendency could have influenced the lower mean size for this period. The sediment type and the bottom temperature appear to influence the behavior of this species and consequently the catch rate during the periods analyzed.
