1. Agro-Industrial Waste Valorization: Transformation of Starch from Mango Kernel into Biocompatible, Thermoresponsive and High Swelling Nanogels
Mango industry processing disposes 40-60% of this fruit as residues, such as peels and kernels. The exploration of bioproducts from these industrial rejects can reduce environmental impact besides of producing high value-added materials. In this scenario, carboxymethyl starch nanoparticles were produced from mango (Mangifera indica L.) kernel starch. These n

2. From classical developmentalism and post-Keynesian macroeconomics to new developmentalism
RESUMO O novo desenvolvimentismo foi uma resposta à incapacidade do desenvolvimentismo clássico e da macroeconomia pós-Keynesiana em liderar os países de renda média para retomar o crescimento. O novo desenvolvimentismo nasceu nos anos 2000 para explicar por que os países latino-americanos pararam de crescer nos anos 80, enquanto os países do Leste As

3. The Role of Carbon Black on Devulcanization of Natural Rubber by Microwaves
One of the greatest problems of the modern society is the recycling of vulcanized elastomers, like tires and industrial rejects. This work studies one of the techniques of devulcanization of natural rubber (NR), the devulcanization by microwaves, as well as the influence of the amount of carbon black on this process through devulcanization of the NR with con

5. Alternativas para o Reaproveitamento de Rejeitos Industriais de Poli(tereftalato de etileno) Reciclado / Alternatives for recycling of industrial wastes of recycled poly (ethylene terephthalate)
The production of nonwoven fabrics (NWF) by extrusion process from recycled poly(ethylene terephthalate) (PET) is an interesting way for polymer recycling used by industry which to allow conciliate economic viability with environmental benefits. However, during extrusion step, a fraction of material is lost due to equipment clogging or others factors, leadin

6. Incorporation of solid wastes in red ceramics: an updated review
A review on the fundamentals and technological advances in the incorporation of industrial solid wastes into red ceramics was updated since 1997, when the first overview on this subject was published by Dondi, Marsigli and Fabbri. Other works conducted before this period, but not covered by that overview were also reviewed. Modifications were introduced in t

7. Um estudo sobre o comercio exterior de bens de capital e algumas de suas relações com o desenvolvimento do ramo industrial no Brasil (1974-1989) / A study on the capital goods foreign trade and some of its relations with the development of industrial sector in Brazil (1974-1989)
In the 1980s and 1990s, liberal narratives about the Brazilian economic development since the 1930s tried to compare it, together with other Latin American countries, the open model of development to foreign trade in East and Southeast Asia. According to the liberal interpretation, the protection model of the internal market to substitute imports would have

8. Dynamic isotherms of dye in activated carbon
Textile industrial wastewaters have significant quantities of dyes. Adsorption processes using industrials rejects may help in the treatment of these effluents. In this context, uptake of Reactive Blue 5G dye by babassu coconut shell activated carbon was studied with upstream flow fixed-bed experiments. First, the minimum flow rate that minimizes the diffusi

12. UTILIZAÇÃO DE METODOLOGIA DE DRENAGEM URBANA PARA ANÁLISE DO COMPORTAMENTO HIDRÁULICO DE UM SISTEMA DE DRENAGEM INDUSTRIAL
The water pollution control by effluents from industrial districts requires that some special attitudes be adopted at the level of each industry. They have to cover the cushioning of the project rain peak, the joint pre-treatment of rainwater and liquid rejects of process. The effluents of each subsystem are combined with sanitary sewer and after the measure
