The objective of this work was to select potato clones for industrial processing, cultivated under subtropical and temperate conditions in Southern Brazil. Thirty advanced clones and three cultivars (control) were evaluated in the Spring of 2007 and 2008, and in the Autumn of 2008, in Júlio de Castilhos, RS (subtropical climate condition), and in the Summer of 2008 and 2009, in São Joaquim, SC (temperate climate condition). It was used a randomized complete block design in a factorial arrangement (33 clones in 5 environments), with two or three replicates of ten hill plots. Yield, appearance, chip color, dry matter and reducing sugar contents of tubers were evaluated. There was a significant interaction between clones and environments for all the evaluated traits, except for chip color. The yield and dry matter of tubers were higher in the summer crop. Environmental conditions affected all the evaluated traits. Growing conditions in Southern Brazil allow for the selection of potato clones with enough content of dry matter to meet the potato processing industry requirements.

A knowledge of rainfall time distribution is important for several types of hydrological studies related to surface runoff. This study aims to determine the time distribution pattern of heavy rain events in Urussanga, Santa Catarina State, Brazil. It employed recording rainfall charts from the meteorological station of Urussanga (latitude: 28.31° S, longitude: 49.19° W, altitude: 49 m) from 1980 to 2007. Rain events were classified into four types according to the duration quartile in which the greatest amount of precipitation occurred. It is found that type I rain events are more frequent, followed by type II, and these occur predominantly during the summer, while type III and IV rain events are distributed throughout the year. In the summer, rain events that last for less than 12 hours are more frequent, whereas during the rest of the year, rain events that last for more than 18 hours are most common.

Macroalgae represent 26 % of the global production of cultivated organisms, with Gracilaria spp. representing 12 % of that production; Eucheuma spp. and Kappaphycus alvarezii account for 34 % of world’s algae production. Despite the potential for cultivating seaweed in Brazil, and with its more than 8000 km of coastline, there is neither marine algaculture nor detailed knowledge even among aquaculture farmers concerning the utility of algae in agriculture, industry, and gastronomy, with the result that algaculture represents only the smallest fraction of national aquaculture production. The main cultivated species of seaweed sold in Brazil include the exotic K. alvarezii and native species of Gracilaria that are grown on small scales and do not meet national industrial demands, which must be supplemented by imports. We discuss Brazilian algaculture here, pointing out some of the problems that restrict commercial production of algae in that country and offer solutions that could be shared with other nations. © 2016 Springer Science+Business Media Dordrecht
Thermal and microscopic analysis of biodegradable laminates made from cassava flour, sorbitol and poly (butylene adipate-coterephthalate) PBAT [Análise térmica e microscópica de laminados biodegradáveis obtidos a partir de farinha de mandioca, sorbitol e poli (butileno adipato co-tereftalato) PBAT]

Blends of biodegradable laminated materials were developed using cassava flour as starch and natural fibers source, sorbitol as a plasticizer and PBAT as a biodegradable polyester. After obtaining pellets from three different formulations, high temperature thermopressure was used to form laminates. The characterization was performed by scanning electron microscopy (SEM) and by differential scanning calorimetry (DSC). The amount of sorbitol for the best extrusion process was 15% (weight/weight) and the formulation of the best homogeneity observed by microscopy was 55:40:15 (flour/sorbitol/PBAT). Although fibers were dispersed throughout the surface in the three treatments, scattered areas of fibers could be found among them. As rates of flour increased, an increase in the melting point of the laminates occurred when compared to pure PBAT.

Elixothrips brevisetis (Bagnall), a species exotic to Brazil, is first recorded in the country. Individuals were collected on banana fruits (Musa sp.) (Musaceae) in July 2010 in the municipality of Luís Alves, state of Santa Catarina, causing rusting on the fruit peel in several bunches of bananas. © 2012 Sociedade Entomológica do Brasil.
