1. Simple and fast process using hydrochloric acid for producing synthetic zinc-rich stevensite
Abstract In the last decades, clays have been used in sectors such as health and cosmetics. This requires products that are increasingly pure and present homogeneous properties, hardly found in natural clays. The use of synthetic clays can be a solution. For this, it is necessary to explore techniques for their production. The main focus of this study was to

2. COMPUTATIONAL ANALYSIS OF LOAD VENTILATION IN BROILER TRANSPORT
ABSTRACT The characterization of ventilation during the transport of broiler chickens is essential for identifying and characterizing the potential problems of a convective heat flow and its effects on the welfare and the health and production conditions of the chickens. The objective of this study was to evaluate the ventilation patterns in two layout model

3. Development of a low-cost alternative for the monitoring of the ore hauling production indicators in small-scale mining
Abstract Small and medium-sized mining represent an important part of a country's min eral economy. These companies, although substantial and numerous, have low invest ment potential in their development through new technologies. One of the problems small and medium mining companies face is the ore hauling production monitoring. This operation alone can cons

4. Fermentation characteristics and in vitro ruminal digestion of yacon residue silage with lactic acid bacteria inoculant or beet pulp
ABSTRACT In this study, we examined the effects of lactic acid bacteria (LAB) inoculant and beet pulp (BP) on the quality of yacon (Smallanthus sonchifolius) residue silage. Yacon silage was prepared using a small-scale system of silage fermentation, and the treatments were as follows: control silage without any additive and silages with LAB inoculant Chikus

5. 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

6. Small-scale Management of Secondary Forests in the Brazilian Atlantic Forest
ABSTRACT Sustainable management of tropical and subtropical secondary forests for multiple purposes, including timber, may encourage farmers to promote regeneration of native forest. We studied the population structures and commercial timber production in two adjacent 33 years-old Brazilian Atlantic Forest stands: a 26 ha forest managed through enrichment w

7. Typology of dairy production systems that meet Brazilian standards for milk quality
ABSTRACT We aimed to compare the typology of dairy production systems (DPS) that meet Brazilian quality standards with that of non-compliant DPS. Semi-structured questionnaires were applied in 128 DPS located in Santa Izabel do Oeste, Paraná, Brazil (25°49'16" S and 53°29'04" W). In addition, milk quality reports of each DPS were analyzed. Dairy productio

8. Length-based estimates of growth parameters and mortality rates of fish populations from a coastal zone in the Southeastern Brazil
ABSTRACT Small-scale fisheries in Brazil contribute to a significant share of total fish production, accessing a large variety of species. Life history parameters from these resources are important for their management and conservation, based on primary data. The objective of this article is to generate growth parameters and mortality rates of ten fish popul

9. Optimum plot size of planting and bio-agroeconomic revenues from arugula-carrot intercropping systems in a semi-arid region
Abstract The production of vegetable crops has been characterized as a highly intensive activity in the use of soil, water, inputs and labor in semi-arid regions, being practiced mostly by small family farmers as a way of subsistence, or in the small-scale commercialization of surplus production. Among the agricultural practices that have been successfully u

10. Assessment of Chemical and Mechanical Properties of Polymers Aiming to Replace the Stainless Steel in Distillation Column
Small scale ethanol production process faces a number of challenges that negatively impact productivity and economic costs. The present work aims at finding alternative materials with lower cost and suitable resistance to replace the stainless steel commonly used in distillation columns in small scale businesses. For that we analyzed the chemical and mechani

11. Production of polymeric nanofibers with different conditions of the electrospinning process
ABSTRACT Nanofibers are materials that present high elasticity, strength, porosity and surface-area-to-volume ratio. The electrospinning method is the most widely adopted technique for forming polymeric nanofibers due to repeatability, easy scale-up process and production of long and continuous nanofibers. This method produces nanofibers with diameters rangi

12. Blackberry Vinegar Produced By Successive Acetification Cycles: Production, Characterization And Bioactivity Parameters
ABSTRACT: Blackberry vinegar was produced in successive acetification cycles and content of total phenolics, anthocyanins and antioxidant activity were evaluated along the production. Firstly, blackberry wine was obtained in bench-scale bioreactor, being verified 0.39 g/g ethanol yield, 1.78 g/L.h volumetric productivity and 76% efficiency. After, three succ
