1. Protein Removal from Natural Rubber Latex with Fe3O4@Al2O3 Nanoparticle
The presence of protein in the natural rubber latex for the medical device manufacture seems to be the most considered compound due to its allergic effect. Magnetic coated alumina (Fe3O4@Al2O3) has been known as an adsorbent for organic substrates due to its performance through physical and/or chemical interaction. In the current study, we tried to figure ou

2. Organic Matter Stocks and the Interactions of Humic Substances with Metals in Araucaria Moist Forest Soil with Humic and Histic Horizons
ABSTRACT Soils with humic and histic horizons in tropical and subtropical ecosystems play an important role in determining the atmospheric C stock and its stabilization, climate regulation, water holding capacity, and environmental filtering, due to the different functions of soil organic matter (SOM). However, the processes and mechanisms that regulate SOM

4. Use of Organic Compost Containing Waste from Small Ruminants in Corn Production
ABSTRACT Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigati

7. Análisis de suelo y foliar en guanábano (Annonamuricata L.) en blanca espuma municipio de Alto Lucero, Veracruz
This study was conducted in a seven years old plantation. Soil and foliar analyzes were performed to determine the physical and chemical characteristics of the soil and the nutrient status of the tree for two climatic seasons (dry and wet). In each of these eight samples were obtained from soil at a depth of 0 to 30 cm, which were mixed to obtain two compoun

10. Reações de obtenção de NOx empregado no processo Humifert para a produção de compostos organofosfatados. / NOx reactions applied in a organophosphated compounds production by Humifert process.
Humiphert process is an alternative used for producing phosphated compound fertilizers with a slower solubilization when compared to other traditional fertilizers, resulting in a longer period of plant nutrition. During the process, phosphatic rocks are used along with some sort of limitation according to the normal development, both by their lower content p

11. Establishment of recommendations and parameters for use of urban waste compost in agriculture in the State of Sao Paulo - Brazil.
The organic matter present in urban waste (45 to 60% of total dry mass), after being stabilized in the form of compost, is recommended for application in agricultural soils, since it improves its physical and chemical properties and benefits the soil biological processes. Also, the urban waste compost has been economically viable for application in agricultu
