A mineração artesanal e de pequena escala em pegmatitos e cerâmica no município de Parelhas, região do Seridó/Rio Grande do Norte

The working conditions, occupational health, occupational illness and workers quality of life, usually referring to the artisanal activities and the workers with a poor professional support. Because this reality is still present in locals without good infrastructure of social and economic attention, there is a need for a broad knowledge of problems related to the productive processes that include features of unsanitary and unhealthy. Despite the intense process of industrialization promoted by globalization and the growth of developing nations like Brazil, the activities of artisanal and small-scale mining are still suffering from the marginalization of their production processes and their workers. This dissertation deals with the description of mineral-based activities (MBA), especially the activities related to production processes of extraction and processing of red pottery and minerals in pegmatites in Parelhas city, Seridó, Rio Grande do Norte, which are conducted by small mining companies or artisanal miners. The study of the work process was based on direct observation, photographic documentation, ergonomics, health and occupational safety analysis, interviews and structured questionnaire with workers of the two activities. The results indicate the need for improvement in both workplaces (red pottery and pegmatites), adaptation of workers to safety standards specific to the workplace, more attention and care related to ergonomics and occupational safety, greater importance to economic and social relations among performed activities, workers and firms of mineral branch and better and greater integration of social policies, supported by different sectors of society with the intention of transforming the current social, cultural, labor and education situation

Recursos pesqueiros oriundos da pesca artesanal no reservatório de jurumirim, rio Paranapanema, Alto Paraná, Brasil

The aim of this paper was to evaluate the artisanal fisheries in the village of fishermen of Bairro da Ponte, Jurumirim reservoir. Data were collected using production forms which were filled daily by a data collector, in 2005 and 2006. The fishery yield was estimated at 15.7 kg ha(-1) year(-1), the average yield was 12.5 t year(-1) and catch per unit effort (CPUE) was 10.5 kg fisherman(-1) day(-1). We recorded 26 species of landed fish in this activity, being the "traira" (Hoplias malabaricus) the most landed fish in terms of biomass with 6,158.5 kg, representing 24.5%, of the total landed. Seasonally, the CPUE ranged from 14.5 kg fisherman(-1) day(-1) in summer/2005 to 9.0 kg fisherman(-1) day(-1) in spring/2006. The average CPUE by type of fish also showed a marked seasonality. In summer of 2005 and 2006, "curimbata" was the most landed fish, with CPUE kg fisherman(-1) day(-1) of 6.9 and 6.2, respectively. The "piavas" were the most landed fish in autumn with CPUE of 2.4 (year 2005) and 2.3 (year 2006) kg fisherman(-1) day(-1), and "traira" in winter with CPUE ranging from 3.0 to 4.0 kg fishrman(-1) day(-1), in 2005 and 2006, respectively. The mathematical modeling of simple linear regression indicated positive relationships between the monthly fish production and the number of boats in activity and of fishing trips. The study concluded that fishing is sustained only by native species; with marked seasonality for catching fish and that the area of fishing examined of the Jurumirim reservoir is among the most productive areas of the Upper Parana basin.

Influência das culturas láticas no índice de proteólise do queijo minas frescal

Estudou-se, a influência de culturas láticas no índice de proteólise do queijo Minas Frescal, processado com leite não pasteurizado e pasteurizado. O emprego de culturas láticas na elaboração de queijo Minas Frescal pode ser indicado, uma vez que o índice de proteólise só se correlacionou com o tempo de conservação.

Efeitos da adubação orgânica e da época de colheita na qualidade da matéria-prima e nos rendimentos agrícola e de açúcar mascavo artesanal de duas cultivares de cana-de-açúcar (cana-planta)

Conduziu-se este trabalho com o objetivo de estudar os efeitos de três sistemas de adubação (30 t. ha-1 de esterco de curral, 3,5 t.ha-1 de esterco de galinha e adubação química - 120 kg.ha-1 de P2O5 e de K2O no plantio + 60 kg.ha-1 de N em cobertura) e três épocas de colheita da cana (julho, agosto e setembro de 2003), na qualidade da matéria-prima e nos rendimentos de colmos e de açúcar mascavo de duas cultivares de cana-de-açúcar (SP79-1011 e RB72454). O experimento foi instalado em área do Alambique JM, Perdões, MG. O delineamento experimental foi o de blocos casualizados, em esquema fatorial (2 x 3 x 3), com três repetições. Não houve efeito dos fertilizantes nos rendimentos de colmos e de açúcar mascavo das cultivares estudadas. Verificou-se efeito de épocas de colheita no rendimento de colmos, com destaque para os meses de agosto e setembro. No entanto, para rendimento de açúcar mascavo nenhuma diferença foi observada. Assim, nas condições deste trabalho, é viável a substituição da adubação química pela orgânica (esterco de curral ou de galinha), sem perdas na qualidade da matéria-prima e nos rendimentos de colmos e de açúcar mascavo artesanal, sendo que os meses de agosto e setembro foram os que proporcionaram matéria-prima de melhor qualidade e maiores rendimentos de colmos.

Estimativa da captura total: desenhos amostrais para pesca artesanal

Estimating total landings of artisanal fisheries in managed areas is essential for the development of programs aimed at the establishment of sustainable production systems. However, few experiences addressed the constraints of assessments targeted at multispecific and small scale fisheries with pulverized landings. Total annual production (fish, lobsters and octopus) at the Marine Extractive Reserve of Corumbau, Bahia, Brazil, in 2006, was estimated through yields recorded by fisherfolks, in the scope of a participatory fisheries monitoring program. Three designs were employed: 1) simple random sampling, 2) stratified random sampling by month and fishing frequency, 3) stratified random sampling by community, fishing frequency and months, resulting in estimates of 349t (95% confidence interval = 305-393), 330t (289-372) and 315t (279-351), respectively. This kind of information can help design strategies for aggregation of value to small scale fisheries production, and also for the dimensioning of the corresponding infrastructure. However, these estimates shall not be used to support fishing effort increase, as there is high uncertainty regarding the state of the stocks, as well as limitations related to the asymmetry in monthly landings per fisherfolk and to the sampling coverage in the different strata.

Aspectos físico-químicos e microbianos do queijo maturado por mofo obtido da coagulação mista com leite de cabra congelado e coalhada congelada

Milk goats are indicated as an economic alternative for small farmers and cheese making could improve their profits. Goat's milk has a seasonal production characteristic and shows periods of abundance and others of scarcity. The use of frozen milk or frozen curd to make cheese can be used to solve the problem. The aim of this work was to evaluate the preparation of cheese made from mixed curd and ripened by Penicillium candidum mould using slow frozen milk (in a domestic freezer) or fast frozen milk (by liquid nitrogen). The slow frozen curd and fast frozen curd without whey were used. It was observed that the cheese from the slow and fast frozen milk and from the slow and fast frozen curd did not differ from the control cheese for the yield, chemicophysical characteristics, chemical composition, extention ripened rate, depth ripened rate and microbiological aspects, even when it was expressed as a dry matter content of cheeses.
