Activated carbon (AC) is a carbonaceous material used to adsorb and remove pollutants. One of the requirements for the material to be considered a precursor in the AC production is its high levels of carbon. Therefore, a promising alternative for the use of forest biomass and its residues would be the application of these materials as precursors in the AC production. Owing to the productive capacity of activated carbon in Brazil and the considerable availability of forest biomass, the objective of the study was to approach the production and market of activated carbon in Brazil. This study is a bibliographic review focused on the use of forest resources for the AC production. AC production occurs by three methods: physical, chemical and physico-chemical activation. At the national level, the main production method is the physical one, since it has the least cost. However, the Sector still requires the researches and technologies aimed at the standardisation and improvements in the whole production chain. [ABSTRACT FROM AUTHOR]

Since zooplankton is the main route of biomass transfer between producers and consumers, zooplankton secondary production is an important measure to evaluate the flow of matter through the trophic levels in aquatic food chains. Secondary production measures may be employed to characterize the zooplankton functional role and to assess the impacts on ecosystem processes and services. The objectives of this study were: 1- to review the main methods to quantify zooplankton secondary production and 2- to carry out a survey of the studies made in Brazil, identifying their gaps, potentialities and perspectives. We conducted a search of publications using secondary production measures in Brazilian aquatic environments in different databases ("Web of Science", "Scopus" and "Scielo"). We found that secondary production measures are based on three main approaches: physiological, enzymatic and population dynamics. The main measures of zooplankton secondary production used in freshwater environments are based on recruitment and biomass increase methods while in transitional and marine environments predominate measures based on growth rate. We found 60 publications among scientific articles, thesis and book chapters developed in Brazil. The studies on zooplankton secondary production have grown in recent years, however most publications were carried out in the southeast region, especially in reservoirs with descriptive approaches. Since there is still a lack of basic information on tropical species and environments, it is important to develop new studies focusing on more complex issues, such as aquatic ecosystems functioning, the effects of environmental changes and anthropic impacts on ecosystem processes and the aquatic environments contribution to biogeochemical global cycles.

During the 1930s, the Czech company Bata Shoes Corporation became a wellestablished multinational organization. It figured amidst the largest shoes producers in the world, being a pioneer in carrying out economic, organizational and social transformations in its internationally widespread facilities. In addition to the improvement of production processes, Bata Shoes Corporation managed to create industrial schools in different countries to train its industrial managers. The company was also recognized for providing workers with habitation located in company towns. In this article, I analyse how production methods and management techniques created by Bata (the Bata System) were implemented in Brazil and Chile, between the 1940s and 1970s. The paper's main objective is to analyse the characteristics of a project which ultimately sought to expand the corporation's control over its workers. I argue that Bata exerted a huge dominance over its employees, specially through pervasive practices related not only to factory dynamics, but also to labourer's private lives.

The flathead grey mullet, Mugil cephalus (Mugilidae), is one of the most commercially important fish species in Taiwan since mullet roe is considered as a delicacy with a high economic value. Farmed, wild-caught, and imported mullet roes are often not properly labelled in retail stores and merchants can make unethical profits from selling mislabeled products. Therefore, there is an urgent need to identify the provenance and production method of the mullet roes. In this study, we conducted a molecular phylogenetic analysis so as to identify the species and geographical origin of the mullet roes and we used stable isotopic values as a tool to differentiate between the wild-caught and farmed mullet roes. DNA sequence variations of a mitochondrial COI gene from the sampled mullets and mullet roes of wild-caught and farmed individuals, as well as the roe products sold in retail stores in Taiwan, were analyzed within the phylogenetic framework. The results showed that the samples were from four M. cephalus lineages (or putative Mugil species B, C, I, and H) occurring in the Caribbean Sea, Northwestern Pacific, and Southeastern Australia, and the M. liza in the Western Atlantic, respectively. The M. liza samples were from the salted roe products purchased from two retail stores, in which one claimed that the roes were imported from Brazil, whereas the other claimed that the roes were from locally reared flathead grey mullets. The farmed mullet roes had significantly lower δ13C values and less variation in δ15N values when compared with the wild-caught and imported mullet roes. Quadratic discriminant analysis based on the δ13C and δ15N values successfully discriminated the farmed mullet roes from the wild-caught and imported roes with an approximate error rate of 2%. Our study demonstrated that the combined approach of genetic and stable isotopic analyses can effectively authenticate the mullet roe origin and production methods. • Mullet roe is considered as a delicacy with a high economic value. • Wrong labelling can make unethical profits from selling those roe products. • Molecular phylogenetics identifies species and geographic origin of mullet roes. • Stable isotope analysis discriminates farmed mullet roes from wild-caught ones. • Combined approach accurately authenticates mullet roe products.
