Herbicide efficacy studies reporting corn yields published in the North Central Weed Science Society Research Report were analyzed to calculate average corn yields for treatments either containing atrazine or not containing atrazine. To prevent unequal comparisons, studies and treatments had to meet conservative selection criteria in order to be included in the analysis. Treatments had to contr...

Materials and Methods The Neely-Kinyon LTAR site was established in 1998 to study the long-term effects of organic production in Iowa. Treatments at the LTAR site, replicated four times in a completely randomized design, include the following rotations: conventional CornSoybean (C-S), organic Corn-SoybeanOats/Alfalfa (C-S-O/A), organic CornSoybean-Oats/Alfalfa-Alfalfa (C-S-O/A-A) and organic Co...

INTRODUCTION This paper reports, for the first time, the presence of Rhodnius stali in the state of Acre and in the Brazilian Amazon. METHODS Specimens of R. stali were collected by the Federal University of Acre in Rio Branco. RESULTS The number of Triatominae species in the State of Acre increased from five to six. This was also the first report of R. stali in the Brazilian Amazon. CONC...

Historically, water allocation focused on quantities demanded by consumptive uses. As quantity demand grows, efficient allocation among consumptive and nonconsumptive uses becomes more critical. This hedonic approach provides information regarding recreational and aesthetic (RA) value for a central Texas lake. The model indicates several statistically significant RA characteristics of housing; ...

This cross-sectional study in a sample of 887 primigravidae in Rio Branco, Acre State, Brazil aimed to analyze factors associated with the use of medicines during the first pregnancy. Information was obtained from interviews and prenatal cards. Medicines were classified according to the Anatomical Therapeutic Chemical (ATC) Classification System of the World Health Organization and risk categor...

The purpose of this article is to investigate the potentials of implementing an integrated Automated Storage and Retrieval System (ASRS) and Automated Guided Vehicle System (AGVS) in maritime container terminals. We first define the main components of the proposed configuration and justify the potential impacts of each and that of the integrated system. A 3D simulation (and animation) model is ...

Southwestern Amazonia is the frontier area between Brazil, Bolivia and Peru. In recent years this region has been faced with IIRSA (Integration Initiative of South American Infrastructure), the huge transnational program to promote integration by transportation and to a lesser degree, with energy, particularly hydroelectric. The center of this area consists of the Department of Madre de Dios, P...

ACRE is an Agro-eConomic model for agricultural pRoduction on rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change scenarios. The validity of the theoretical approach as well as the algorithms has been tested by calculations with empirical data. Currently, ACRE is appl...
