Fragmentos de um modelo: pequenas lavouras de café e acumulação de capitais. Franca/São Paulo 1890-1914

Este artigo versa sobre a importância da pequena cafeicultura no complexo cafeeiro entre 1890 e 1914. Discutimos aqui as relações de trabalho, as formas de financiamento e o modo como a pequena propriedade se insere neste universo. Utilizamos como fontes prioritárias os contratos de trabalho que envolviam a formação e/ou o trato de cafeeiros e as escrituras de dívidas hipotecárias, ambas lavradas nos Livros Cartoriais, fontes estas ainda não trabalhadas pela historiografia de forma mais sistemática. Desviamos nosso olhar para uma região marcada predominantemente pelas pequenas e médias fazendas produtoras de café, observando a dinâmica da acumulação em um período de expansão e de crise da cafeicultura.

Relative growth of spider crab Acanthonyx scutiformis (Dana, 1851) (Crustacea, Decapoda, Majidae)

The dimensions of chelar propodus and abdomen were utilized for the morphometric analysis about the relative growth studies of Acanthonyx scutiformis (Dana, 1851). A total of 297 specimens (114 males and 183 females), was collected in Ubatuba, State of São Paulo, Brazil. The animals were sexed and soarted to maturation phase (immature and mature). The following measurements were made: carapace (length and width), abdomen width and chelar propodus (length and height). In this study was applicated the power function (y= a.x(b)), in which the growth was considered positive allometric with isometric with b=1, and negative allometric with b<1. The alometry becomes isometric, when the results concerning immature and mature females and males are analysed. In the Brachyura male chelipeds are utilized in territorial defense, fight, display and courtship and female abdomens are utilized as a chamber that protect and incubate the eggs.

Distribution of Neohelice granulata (Dana 1851) in its northernmost latitudinal occurrence in a tropical mangrove forest, Brazil (Crustacea, Decapoda, Brachyura, Grapsoidea, Varunidae).

Neohelice granulata ecological distribution was evaluated in its northernmost latitudinal occurrence in a Brazilian tropical mangrove (23[degree]13'4" S, 44[degree]42'47" W). Samples were collected in three sites along the main river in the mangrove. Crabs were manually captured by two people, 15 min each, at low tide periods. The sex of the animals was assessed and carapace width measured. The size-frequency distribution was determined in each site. Environmental factors (salinity, temperature, organic matter and sediment texture) were analyzed, compared among sites and related to crab abundance and size in each site. Crab abundance decreased with the distance from the sea. Juvenile crabs were more frequent next to the sea, whereas larger and ovigerous ones were mainly found in the most distant site. Crab size was proportional to the organic matter percentage in the sediment. N. granulata spatial distribution varies along the river course, which is probably related to the most productive areas that have more nutrients available; this may also occur in order to prevent intraspecific competition.

Desenvolvimento pós-embrionário de Ceraeochrysa cincta (Schneider, 1851) (Neuroptera: Chrysopidae) alimentada com ovos de Diatraea saccharallis (Fabricius, 1794) (Lepidoptera: Crambidae)

The lacewings (Ceraeochrysa cincta) are important predators found associated to many pests in several agroecosystems. Eggs of Sitotroga cerealella and Anagasta kuehniella are used traditionally for massal rearing of these predators. Other foods can be used in substitution to the traditional ones, but little is known about the biology of lacewings and other alternative foods. So, this work was carried out to evaluate the effect of different diets on the post-embryonic development of C. cincta in laboratory. After been individualized in glass tubes, each larva was fed with S. cereallella and Diatraea saccharallis. It was evaluated the larvae duration, weight and viability in each instar, the duration, weight and viability of the pupa and pre-pupa stages and the duration of the post-embryonic period. It was adopted a completely randomized design with ten replications per treatment, each consisting of five eggs or larvae of C. cincta. Larvae were weighed 48 hours after hatching and 48 hours after each molt, and pre-pupae and pupae, 48 hours after starting these stages. There was no effect of the kind of food provided on the parameters evaluated. Therefore, D. saccharallis eggs can be used to feed C. cincta.

Crédito e pequena cafeicultura no oeste paulista: Franca/SP 1890-1914

This article turns on the importance of the small coffee production in the coffee complex economy between 1890 and 1914. We argue here the relations of work, the forms of financing and the way as the small coffee production inserts itself in this universe. We use as priority sources the employment contracts that involved the formation and/or the treatment of coffee trees and the Writes of mortgage debts, both recorded in Notarial Books, documents not used by historiography in a systematical way. We turns our look for a region marked predominantly for small and the middle producing farms of coffee, observing the dynamics of the accumulation in a period of expansion and crisis of the coffee economy.

Mutual occlusion between real and virtual elements in Augmented Reality based on fiducial markers

Augmented Reality (AR) systems which use optical tracking with fiducial marker for registration have had an important role in popularizing this technology, since only a personal computer with a conventional webcam is required. However, in most these applications, the virtual elements are shown only in the foreground a real element does not occlude a virtual one. The method presented enables AR environments based on fiducial markers to support mutual occlusion between a real element and many virtual ones, according to the elements position (depth) in the environment. © 2012 IEEE.
