-
(Editora da Universidade Estadual de Maringá - EDUEM, 2017-07)The objective of this study was to model the kinetics of water sorption in roasted and ground coffee. Crude Arabica coffee beans with an initial moisture content of 0.1234 kg w kg dm-1 were used. These beans were roasted ...
-
(Instituto de Pesquisas Ambientais em Bacias Hidrográficas, 2014)This study evaluated the treatment of wastewater from coffee wet processing (WCWP) in an anaerobic treatment system at a laboratory scale. The system included an acidification/equalization tank (AET), a heat exchanger, an ...
-
(Sociedade Brasileira de Química, 2020)Thermal decomposition of coffee husks was investigated by thermogravimetric analyses. The proximate, ultimate and composition analyses were performed. Thermogravimetric tests were realized, the material was heated to 1173 ...
-
(ABM, ABC, ABPol, 2021)Biotechnology can be used to convert waste into valuable products. In this context, there is bacterial cellulose (BC), a natural biopolymer that can be transformed into several useful materials, but its production is limited ...
-
(Sociedade Brasileira de Ciência do Solo, 2008-03)Kinetic studies on soil potassium release can contribute to a better understanding of K availability to plants. This study was conducted to evaluate K release rates from the whole soil, clay, silt, and sand fractions of ...
-
(Associação Brasileira de Engenharia Agrícola, 2016-03)Roasting is one of the most complex coffee processing steps due to simultaneous transfers of heat and mass. During this process, beans lose mass because of fast physical and chemical changes that will set color and flavor ...
-
(Editora UFLA, 2013-01)Blotch progress lifting becomes potentially useful and understandable in understanding the disease and in the process of decision taking for control measures. In the last years, computer programs have been helping to ...
-
(Universidade Federal de Lavras, 2023-10-03)Lactic acid bacteria (LAB) are recognized in coffee fermentation as key microorganisms in forming flavor and aroma precursors associated with high-quality beverages. In Colombia, although coffees with differential sensory ...
-
(Associação Brasileira de Engenharia Sanitária e Ambiental – ABES, 2019-07-29)A set of experiments were carried out in order to establish and evaluate the potential of activated carbon, produced from coffee waste in adsorption process, in the depuration of landfill leachate. Different reagents were ...

-
(Sociedade Entomológica do Brasil, 2010-07-22)Five Coccus on Coffea arabica from the states of Bahia, Espírito Santo and Minas Gerais were studied. Females were prepared and mounted in Canada balsam. Coccus brasiliensis Fonseca and Coccus lizeri (Fonseca) were redescribed ...
-
(Editora UFLA, 2021)In coffee plants, fertigation can be an alternative way to minimize the negative effects exerted by drought and maximize fertilizer use efficiency. However, the fertilization recommendations for fertigated coffee trees are ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2019)The leaf area index (LAI) is relevant in studies of phenomena at different scales, such as for the leaf to canopy scale and the calculation of the extinction coefficient of photosynthetically active radiation (kPAR), ...
-
(Universidade Federal de Santa Maria, 2019)Coffee crops play an important role in Brazilian agriculture, with a high level of social and economic participation resulting from the jobs created in the supply chain and from the income obtained by producers and the ...
-
