“…Based on the present results, it should be highlighted that local temperature needs to be correctly managed for seedling production, since it may directly affect plant metabolism. Temperature interferes with the enzymatic activities (BELETI et al, 2012) and photosynthetic capacities (SHIMADA et al, 2017) of several plant species. The damage caused by high temperatures are reflected in chlorophyll fluorescence levels, since plants subjected to high temperatures present decreased photochemical quenching and increased non-photochemical quenching, decreasing the quantum efficiency of photosystem II (PSII) (XU et al, 2014).…”

Sugar apple (Annona squamosa L.) is one of the most widely grown member of the Annonaceae family in several regions, but there is still a lack of agronomic data regarding the management of its initial growth stages under Cerrado conditions. The aim of the present study was to evaluate the production of Annona squamosa L. seedlings under different environmental conditions achieved by using shade nets (E1: ChromatiNet® Silver 50%; E2: ChromatiNet® red 50%; E3: ChromatiNet® red 35%; E4: ChromatiNet® Silver 35%) in combination with four different substrates (S1: soil + sand + chicken manure; S2: soil + sand + cattle manure; S3: soil + sand + cattle manure + chicken manure; S4: soil + sand + sheep manure). An experiment was set up using a completely randomized design with treatments in a split-plot arrangement, with four replicates and ten plants per experimental unit. Seedling growth parameters and quality indices were evaluated. The tested environments had higher local temperatures relative to the external environment, which had a negative effect on plant growth. Environment E2 resulted in the highest plant height and dry weight, but led to uneven growth among the evaluated plant parts. The substrate with sheep manure (S4) did not benefit seedling production. The best results for seedling growth and quality were obtained with substrates S2 (soil + sand + cattle manure) and S3 (soil + sand + cattle manure + chicken manure), which are therefore promising for Annona squamosa L. seedling production in the Roraima Cerrado.

“…In beer production, barley grain (Hordeum vulgare L.) is mainly used as a source of starch. According to Beleti, Duarte and Georg-Kraemer (Beleti;Duarte;Georg-Kraemer, 2012), the barley grain is the 5 th most used cereal in the world. However, for socio-economic reasons, other sources of starch are also applied in beer production, such as rice, corn, sorghum, oats and wheat.…”

Intensification of barley hydration process using periodic operation was evaluated as compared to isothermal hydration conditions (20 C). Periodic operation resulted in an 82.88% saving in time, and consequently, energy. The Peleg model exhibited satisfactory fit to the experimental data for the hydration kinetics. The mass transfer coefficient of the periodic operation (K SPER15-30 = 0.55 cm h −1 ) obtained by the Omoto-Jorge model was higher than that observed for the isothermal hydration (K SISO = 0.42 cm h −1 ); the hydration rate was increased by 31% for an amplitude of 15 C and a period of 30 min. The isothermal diffusion coefficient presented a value of 68.31 × 10 −12 m s −2 and a periodic diffusion coefficient of 78.61 × 10 −12 m s −2 for the hydration process. The intensification of the hydration process because of the periodic operation did not negatively affect the energy and germination index of the barley grains. Practical ApplicationsThe present work describes the impact of periodic operation on barley hydration. This mode of operation may be applied practically as a new process intensification strategy for the brewing industry. Periodic operation proved to be more efficient than the conventional process, resulting in faster water absorption rates and a shorter hydration time; consequently, a lower amount of energy is required for the hydration process. Since the grain germination index and germination energy remained unchanged as compared to the conventional process, periodic operation appears to be a very promising technology for malt production. The mathematical models obtained adequately described the behavior of the hydration kinetics and allowed the mass transfer coefficient to be evaluated; thus, they may be used in the project, optimization and simulation of the process.
