The collections of Lauraceae in the Herbarium of Henri Van Heurck (AWH)

Background and aims - The collections of Lauraceae in the Van Heurck Herbarium (AWH), which is currently on permanent loan to BR, have remained unknown by most of the specialists and by the general public up until the present. The taxonomic status of its one hundred and forty nine specimens of Lauraceae is here presented.Methods - Standard herbarium taxonomy practices were used in conjunction with the literature available. Specimens from fifty eight different herbaria were studied personally, or by checking their holdings available in the internet, or from digital images received from the curators.Key results - The specimens of Lauraceae from AWH are distributed in twenty four genera and seventy eight species with taxonomic status resolved, excepting for three specimens pertaining to species name of status uncertain (one), or to unresolved determination (two). From them, fifty three specimens are nomenclatural types of any sort, which corroborate the relevance of exsiccates acquired by Van Heurck, even for this relatively small set of specimens for the family. Fifteen lectotypifications and one neotypification of species names are proposed here.

Cultura organizacional: uma análise da microempresa familiar informal

Analyze possible relationships between the bankruptcy and the family structure of informal micro-enterprises in Fortaleza city, Brazil. The analysis began with a research among micro-entrepreneurs who were beneficiaries of PROFITEC loans in bankruptcy and non-bankruptcy situation in 1997-1999 period. Evaluate whether the overlap of family and professional relationship inside the organizational structure of those micro-enterprises is a factor leading to bankruptcy. The comparative analysis divides the micro-enterprises into two groups: one that which had complied with the loan obligations (abiding firms) and another which had not (non-abiding firms). The analysis pointed out the familiar structure as having positive and negative influences over organizational work in both groups. The research also realized that those groups of family informal micro-enterprises do not recognize the professional problems related to the family, giving room for managerial conflicts related to the compliance, work time and use of profit. We cannot say that family structure of the informal microenterprises is the decisive cause for non-abidance, since there are also family firms which have the same disadvantages of both groups, but are complying with their obligations. The personal relationships in the informal family firms, however, define good practices and behaviors that definitely affect their operations.

Análiseda percolação de água em barragem de terra pelo método da eletrorresistividade

Interventions in nature made by man are very common since the beginnings of human history, especially in the case regarding the storage of water. The construction of dams have been and still are fundamental in maintaining human life due to the vital importance that water plays. The size of these structures vary according to need, such as water catchment, fish-farming or electricity generation. Embankment dams are the most common type of these structures. Can be defined as dams natural material obtained from loan chambers located near the dam site. This type of barrier may be divided into earth dams and rockfill dams. The study area covers an earth dam located in Cordeirópolis (SP) and is essentially composed of diabases altered soil of the Serra Geral Formation of the Paraná Basin. With the aid of geophysics, more specifically of the Electrical Resistivity method, the aim is to check any water infiltration zones in the dam's body. Given the risks associated with water seepage in earth dams, that may generate breakdown structures, erosion, and consequently accidents and / or harmful factors in the nearby areas. One of the main structural problems married by water infiltration is the possible generation of pipes that could jeopardize the dam structure. This work aims to contribute towards the evaluation of the effectiveness of using an indirect technique of research and monitoring in aid to direct research techniques such as piezometers and drive stakes. The results are presented in the form of 2D and 3D geophysical models, the analysis shows a low resistivity zone with typical values of the presence of humidity originating upstream of the dam and downstream bottleneck trend, that are the basis for interpretation by percolation or not water in the dam

Socioeconomic, financial and production infrastructure profile of farmers in rural settlements in the western region of the state of São Paulo, Brazil

Family agriculture, mostly represented by rural settlements especially in the state of São Paulo, makes up rural establishments in Brazil. Current investigation collects, analyzes and compares data on farmers on two rural settlements in the western region of the state of São Paulo, specifically in the municipality of Rancharia, with regard to their socioeconomic, financial and productive infrastructure profile, coupled to information on eventual restrictions to rural credit, by an analysis based on descriptive statistics. Results show that there are different factors between farmers and production systems, which cause loan restrictions due to such differences as age, agricultural and cattle-breeding activity, technical assistance and management. The valorization of these differences should be taken into account for the construction of new events, without extremes, and work for situations featuring demand-based development and characteristics of the locality

Consumo de combustível de um trator agrícola em função do tipo de soloe da pressão de inflação nos pneus utilizando o equipamento canteirador

Agricultural mechanization improved the efficiency of field operations by providing an increase in crop production. The intensified mechanization, however, has led to higher energy use mainly in the area of fuel consumption. The objective of this study was to compare the fuel consumption of tractors using two different tire pressures for two different types of soil during tillage with irrigated cotton in semi-arid regions. These tests were performed at the Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona with a Case 4x2 TDA 88kW equipped with an autopilot system. The results showed lower fuel consumption using a tire pressure of 124 kPa on sandy clay loan soil.

Analyzing ACRE: Results for 2009 and Decisions for 2010

In 2009, agricultural producers participating in federal farm programs had to decide between staying in the existing Direct and Counter-Cyclical Program (DCP), and the new Average Crop Revenue Election Program (ACRE). If producers chose to keep the DCP, their farm income safety net is strictly tied to crop prices, with a combination of marketing loans, counter-cyclical payments and direct payments. If producers chose the new ACRE program, they changed their farm income safety net to a combination of price and revenue. The new ACRE component is based on revenue and replaces the counter-cyclical payment. The other parts of the safety net for ACRE participants remain tied to price, albeit at lower levels (direct payments reduced 20 percent, marketing loan rates reduced 30 percent).

Reaffirm to Affirm: Enhancing Minority Faculty Development at the PWI

The objective of this roundtable discussion is to examine the preparation of minority faculty as it relates to succeeding in an academic career. Although substantial research has been conducted on faculty preparation (Gaff, 1997; Garcia, 2000, Tice, Gaff, and Pruitt-Logan, 1998), conversations fall short when it comes to ongoing success development of faculty. This discussion will focus primarily on initiatives/plans to encourage the expansion and success of minority faculty at PWI's. For the purposes of this discussion, minority faculty is defined in terms of race/ethnic and gender.

Iheringichthys syi (Siluriformes: Pimelodidae), a new pimelodid species from upper Paraná basin, Brazil

We describe a new species of pimelodid catfish of the genus Iheringichthys from the upper Paraná basin, Brazil. Iheringichthys syi n. sp. is distinguished by the comparatively fine serration along the anterior margin of the pectoral-fin spine, an adpressed dorsal-fin remote from the adipose-fin origin, a large eye (23.2-31.2% of head length), narrow interorbital (16.2-23.0% of head length), long snout (42.0-51.0% of head length), long postorbital length (30.6-34.0% of head length), low adipose fin (4.8-7.8% of standard length), eye diameter 97.0-140.0% of interorbital length, and body with numerous, small dots irregularly scattered on flanks, especially marked on anterior half of flank.

A new armored catfish species of the genus Hypostomus Lacépède, 1803 (Siluriformes: Loricariidae) from the upper rio Xingu basin, Brazil

A new armored catfish species of the genus Hypostomus is described from the upper rio Xingu basin, Mato Grosso State, Brazil. The new species is diagnosed from congeners by having high number of teeth (58 to 101, mean 77 on premaxilla, and 58 to 105, mean 80 on dentary), dark spots over body and fins, and abdomen mostly naked. The new species is known from the rapids of the rio Culuene, where it is sympatric with Hypostomus faveolus.

The cascudos of the genus Hypostomus Lacépède (Ostariophysi: Loricariidae) from the rio Iguaçu basin

We reviewed several large collections of the genus Hypostomus from the rio Iguaçu basin summing up to 793 specimens mainly from the Laboratório de Ictiologia do Departamento de Ecologia e Biologia Evolutiva from Universidade Federal de São Carlos, from fish collection of Núcleo de Pesquisas em Limnologia, Ictiologia e Aquicultura da Universidade Estadual de Maringá, and from the Museu de História Natural do Capão da Imbuia. Hypostomus albopunctatus, H. commersoni, H. derbyi, and H. myersi are redescribed and Hypostomus nigropunctatus is described as a new species. A practical key for identification of Hypostomus species from the rio Iguaçu is also provided.

Two new species and a review of the inseminating freshwater fish genus Monotocheirodon (Characiformes: Characidae) from Peru and Bolivia

Two new species of inseminating freshwater fishes of the genus Monotocheirodon, family Characidae, are described from Peru. Males and females of both new species have an external, visually obvious urogenital papilla that was not detected in the females in previous studies, with this longer in males, which use it as an inseminating organ. A third inseminating species from Bolivia, Monotocheirodon pearsoni, unstudied in any detail since its original description in 1924, is redescribed. This latter species lacks an inseminating organ. Monotocheirodon is redescribed, its phylogenetic relationships are briefly discussed and it is suggested that it is possibly related to the stevardiin genera Ceratobranchia, Othonocheirodus, and Odontostoechus.
