1. Study of the Potential of Photovoltaic Microgeneration and Minigeneration from the Grid-Connected Photovoltaic Systems Installed at UTFPR Curitiba Campus
Abstract: Humanity is increasingly dependent on energy, which demand grows every year. Renewable energy sources are consolidated alternatives in the market, previously installed on a small scale but now thought as large plants. The correct operation, taking full advantage of the generation potential, depends on studies of the place of implantation, such as r

2. Progresso temporal da queima das folhas em diferentes genótipos de cenoura
RESUMO A cultura da cenoura tem se expandido em diversos locais do Brasil e na região do Alto Vale do Itajaí, SC, grande parte da sua produção vem de agricultores familiares. Entretanto, a queima das folhas (Alternaria dauci) tem comprometido a produtividade. O objetivo do trabalho foi avaliar o progresso desta doença nos genótipos: Alvorada calibrada

3. GRANULOMETRY AND ENERGY CONSUMPTION AS INDICATORS OF DISINTEGRATION EFFICIENCY IN A HAMMER MILL ADAPTED TO EXTRACTING ARROWROOT STARCH (Maranta arundinacea) IN COMPARISON TO STARCH EXTRACTION FROM CASSAVA
ABSTRACT The commercial sector of starch extraction has fully automated plants with a minimum scale of 200 ton.day–1, which extracts starch from maize and cassava in Brazil. Although these starches are commodities, the market demands starches with special properties obtained without chemical modifications. A higher-priced starch can compensate for small-sc

4. Small-scale environmental enrichment and exercise enhance learning and spatial memory of Carassius auratus, and increase cell proliferation in the telencephalon: an exploratory study
Carassius auratus is a teleost fish that has been largely used in behavioral studies. However, little is known about potential environmental influences on its performance of learning and memory tasks. Here, we investigated this question in C. auratus, and searched for potential correlation between exercise and visuospatial enrichment with the total number of

6. A new methodology for large-scale screening sugarcane resistance to Mahanarva Fimbriolata (Hemiptera: Cercopidae)
ABSTRACT The sugarcane spittlebug, Mahanarva fimbriolata (Walker) (Hemiptera: Cercopidae) is an economically important pest of sugarcane in Brazil. The purpose of this study was to develop and validate a greenhouse methodology to screen large sugarcane populations for resistance to spittlebug Mahanarva fimbriolata. A resistant and a susceptible genotype (H.

7. CONSTRUCTION AND PRACTICAL APPLICATION OF A CANOPY OPENER DEVICE
ABSTRACT: Accurate application of pesticides is difficult for crops with dense leaves, such as soybean crops. To improve spray deposits on the lower leaves of soybean plants, the aim of this study is to build a canopy opener (CO) from a previously developed prototype and to assess its practical application and efficiency on soybean crops. Laboratory experime

8. Reproductive phenology, seed removal and early regeneration in relation to distance from parental plants of a native palm in small Atlantic forest fragments
ABSTRACT The Brazilian Atlantic Forest is a global biodiversity hotspot, but most of what remains are small fragments. Small fragments are often harsh environments for forest plant recruitment due to edge effects and the loss of frugivorous animals that provide seed dispersal. We recorded the one-year reproductive phenology of the keystone palm Syagrus roman

9. Propuesta de descriptores para Acca sellowiana (Berg.) Burret
The feijoa plants [Acca sellowiana (Berg.) Burret] is one of the most valued genetic resource plants underutilized from Uruguay and Brazil. This tree is endemic of a narrow area of South America, comprising the northeast of Uruguay and the south of Brazil. Beyond the fact that it has edible fruits, cultivation is limited to domestic scale or small orchards.

10. Cost efficiency of cryopreservation as a long-term conservation method for coffee genetic resources.
Coffee (Coffea spp.) is one of the world?s most valuable agricultural export commodities produced by small-scale farmers. Its germplasm, which holds useful traits for crop improvement, has traditionally been conserved in fi eld genebanks, which presents many challenges for conservation. New techniques of in vitro and cryopreservation have been developed to i

12. RESÍDUOS DE AGROINDÚSTRIAS FAMILIARES: IMPACTOS NA QUALIDADE DA ÁGUA E TRATAMENTO COM TÉCNICAS SIMPLIFICADAS / WASTE OF AGRO-INDUSTRY FAMILY: IMPACT ON WATER QUALITY AND TREATMENT WITH TECHNIQUES SIMPLIFIED
Human activities have altered the environmental quality especially with regard to water sources. The agro-industry activity in small scale may represent a potential pollutant different from those of other agricultural activities, and, therefore, there is the need to search alternatives to minimize its impacts. This work aims to: (a) assess the quality and qu
