1. Technical contributions to territorial planning and the use of ecosystemic services in a hydrographic basin with a water deficit in the Atlantic Rainforest of Brazil
Resumo A bacia do rio Dois Rios (R2R) (3.159 km²) recolhe os efeitos climáticos e ambientais típicos de zonas situadas a sotavento de cadeias montanhosas. Tem balanço hídrico deficitário, havendo poucos e específicos locais úmidos. Este estudo identifica, espacializa, caracteriza e agrupa as planícies de inundação com maior habilidade em produzir

2. Influencia del calcio en la retención de humedad por arcilla
ABSTRACT Bentonite as a raw material is an economical alternative to produce desiccants. The literature indicates that it is a good water adsorbent in relation to the desiccants commonly used in industry (silica gel, molecular sieve). In this sense, it is a valid alternative and an economic option since the clay is a natural compound, which makes it environm

3. Combination of Propylene Glycol Alginate and Lauric Acid on Water Retention and Mechanical Properties of Soy Protein Isolate-Based Films
The water sorption, water barrier properties and mechanical behavior of soy protein isolate (SPI) based films combined with propylene glycol alginate (PGA) and lauric acid (La) via a direct- or co-dried blending process were investigated. Higher water retention ability and a single glass transition temperature (Tg) were found when the PGA was added to form d

4. Crosslinkable potato starch-based graft copolymer emulsion for humidity controlling coatings
A new kind of crosslinkable potato starch-based graft copolymer emulsion (PoSt-g-BMD) has been prepared using butyl acrylate (BA) and methyl methacrylate (MMA) as main monomers, and diacetone acrylamide (DAAM) as functional monomer. The keto-carbonyl group of DAAM in PoSt-g-BMD copolymer could react with adipic dihydrazide (ADH) at ambient temperature to for

5. DISPONIBILIDADE HÍDRICA NA PRODUÇÃO DE GIPSOFILA (GYPSOPHILA PANICULATA) EM VASOS COM SUBSTRATO DE CASCA DE ARROZ CARBONIZADA / WATER AVAILABILITY ON GIPSOFILA (GYPSOPHILA PANICULATA) GROWING IN POTS WITH SUBSTRATE RICE HUSK CARBONIZED
Ornamental plants in general are highly susceptive to water deficiency, principally to the elevated soil water level variation that effects at a precarious and uneven final product development. The study was conducted on greenhouse at the Universidade Federal de Santa Maria, RS. It aimed to observe if rice husk ash substrate offers limitation to the pot cult

6. Influence of osmotic dehydration on ascorbic acid loss in pickled dry peppers (Capsicum chinense)
The objective of this work was (1) to develop a dehydrated pepper with 45% humidity, determining the drying curves for pepper, with and without osmotic pre-treatment and (2) to evaluate the influence of both drying and osmotic treatment on the content ascorbic acid (vitamin C) in fresh pepper and pepper with 45% humidity. The experiments were carried out usi

7. MamÃo (Carica papaya L.) liofilizado em pÃ: avaliaÃÃo das caracterÃsticas fÃsicas, fÃsico-quÃmicas e higroscÃpicas / Papaya (Carica papaya L.) lyophilized powder: evaluation of physical, physicochemical and hygroscopic characteristics
Papaya (Carica papaya L.) is a tropical fruit known and appreciated worldwide. Their sensory and nutritional characteristics contribute to the wide acceptability of this fruit. However, in the post-harvest loss is high due to its highly perishable. In this context, the lyophilization appears as a promising process for dehydration of papaya, because is a dryi

9. APLICAÇÃO DE PRODUTOS DA FERMENTAÇÃO E ULTRABAIXO OXIGÊNIO PARA A CONSERVAÇÃO DE MAÇÃS ROYAL GALA
The aim of this work was to evaluate the effect of post harvest ethanol or acetaldehyde application and to compare them with consolidated storage techniques on the quality maintenance of Royal Gala‟ apples. Also, we aimed to evaluate the effect of controlled atmosphere condition with ultra low oxygen partial pressures on the post storage quality mainte

10. Zoneamento florístico em campo ferruginoso em uma área do sul-sudeste do quadrilátero ferrífero, MG
This study presents the floristic and fitossociologic inventory of an area of a rupestrian ferruginous field located in Serra de Antônio Pereira, in the south southeast region of Iron Quadrangle in Ouro Preto, Minas Gerais. In order to collect data, 15 sample units of 10x10m were limited in each litotype of the substract studied: canga couraçada and itabir

11. Conservação refrigerada de lima ácida "Tahiti" em combinação com atmosfera modificada, ácido giberélico e permanganato de potássio / Cold storage Tahiti lime in combination with modified atmosphere, gibberellic acid and potassium permanganate
Although Brazil is the largest producer and exporter of Tahitilime, actually, exports only 5% of total production. This is, in part, because of a lack of quality of these limes, characterized by loss of green skin colour after harvest. The purpose of this research was to evaluate the efficiency of modified atmosphere, gibberellic acid (GA) and potassium perm
