Procedendo a um estudo textual e discursivo do verbo, demonstramos como o presente futuro se realiza na construção do texto falado no português brasileiro, verificando seus valores temporais e modais, como também seu contexto de ocorrência. Destacamos que o caráter prospectivo do presente do indicativo, marcado pela relevância do presente do falante, desencadeia-se a partir da interação entre o valor semântico do radical verbal, a flexão, a situação discursiva e o marcador temporal.

Skeletal muscle growth in the pirarucu (Arapaima gigas) is highly interesting to fish farmers because it provides information about how the mechanism in muscle mass increase, characteristic of the species, is regulated. Pirarucu has specific muscle growth that highlights the species's significance and commercial value. Current research evaluates the morphology and the growth-related gene expression in the red and white skeletal muscles of the pirarucu. Muscle samples were collected from the lateral anterior region and frozen in liquid nitrogen. Histological sections were performed and stained by HE for morphological analysis. Red and white muscle samples were used to determine MyoD, myogenin, and myostatin genes expression by Real-time Polymerase Chain Reaction. Although MyoD and myogenin were not statistically different in the two types of muscles, myostatin was significantly higher in the white rather than in the red muscle. Results show the muscle growth characteristics of the species and may be helpful for improving aquaculture management programs.

This survey was conducted with the objective of developing and adapting diagnostic techniques in neurology for non-human primates, of the species Alouatta guariba Geoffroy Saint-Hilaire, 1812 (howler monkey) healthy and kept in captivity. Physical-chemical analyses were carried out in cerebrospinal fluid and its pressure measurement in the cisterna magna. Eight animals were used for the analysis of cerebrospinal fluid. In all procedures, were used chemical restraint and anesthesia with ketamine, xylazine and association of midazolam and inhalational anesthesia with isoflurane for carrying out the spinal tap. The cerebrospinal fluid analysis showed average values: protein: 16.92±9.84; glucose: 131.25mg/dL±106.7; pH: 8.37±0.69; nucleated cells: 0.5/mm³±0.75; red blood cells: 49.37/mm³±111.76 and CSF cisternal pressure: 7.37cm H2O±1.77. This study demonstrated the safety and efficacy of cerebrospinal fluid collection in the cisterna magna of Alouatta guariba, and the reference values for the specie.

Sustainability has been moving up on the business agenda in recent decades, and many methods to assess corporate sustainability have already been created. One of the most used and reliable methods is the Sustainability Reporting Guidelines of the Global Reporting Initiative (GRI). Given the importance of sustainability for society and organizations, this study examined sustainability reports published by mining companies – Alcoa, Vale and Samarco – since 2006. The objective was to verify the indicators that contribute most to the minimization of environmental impacts and the improvement of environmental performance. The methodology consisted of collecting and analyzing data from the GRI sustainability reports. It was discovered that the sustainability reports helped the companies to identify improvement opportunities and it is essential companies provide in their reports an economic, environmental and social context of their activities. Furthermore, it was found out that the indicators related to atmospheric emissions, solid waste generation, environmental protection expenditure, and the consumption of raw materials, energy and water are the ones more attached to the production process, which means they are the main contributors for the environmental performance improvement

O Ácido Kójico (AK) é uma substancia produzida por cepas de Aspergillus sp. Foi isolado pela primeira vez em 1907, através do estudo feito a partir do crescimento desse fungo em arroz cozido a vapor. É usado na cosmetologia como antioxidante e despigmentante para uso tópico. Atua como um potente antioxidante quelando íons de ferro e os íons de cobre presentes no seu sítio ativo da tirosinase impedindo a formação de melanina. O isononanoato de cetoestearila, utilizado na formulação, tem ampla utilização em cosméticos como cremes protetores de epiderme, cremes de maquiagens, cremes de proteção solar, loções e desodorantes por ser emoliente, não possuir cheiro e toque seco. Os sistemas nanoestruturados, como por exemplo, os sistemas líquidocristalinos aumentam a solubilidade dos princípios ativos incorporados ao sistema e aumentam a solubilidade dos princípios ativos incorporados ao sistema e aumentam a estabilidade e diminuem a toxidade, pois agem como reservatórios e dependendo da interação fármaco-sistema, altera a biodisponibilidade. O presente trabalho tem como objetivo desenvolver e caracterizar um sistema líquido cristalino constituído por água e isononanoato de cetoestearila (óleo), e estabilizado com o tensoativo álcool cetílico etoxilado e propoxilado contendo ácido kójico avaliando sua estabilidade através de estudos de termoanálises

The study aims at approaching the duty concept (Sollen) within Kant´s moral philosophy. Taking into account the notion of moral duty as one of the central concepts in (and to) Kant's practical thought, and in an attempt to offer an elucidation of Kant’s quest (and development) by the supreme principle of moral – the fundaments of the moral value´s detaining action, we will investigate: i) what characterizes one action for duty, in Kant’s moral thought and, ii) why exactly, according to Kant, just the action, precisely for duty, is the only action with the genuine value, namely, the moral value.

The aim of this paper was to evaluate the efficiency of the treatment of cassava wastewater, separately from the root washing water, by means of ascending flux anaerobic digesters, with separation of the phases, without temperature control or addition of chemical products and to evaluate its suitability by means of its physical and chemical characteristics for throwing in receiving body, public sewage system or application in fertilization and irrigation. After reactors had been stabilized, essays were conducted varying feeding flow with 8.0, 12.0 and 16.0 Ld-1 corresponding to a hydraulic retention time of 8.17, 5.44 and 4.08 days, respectively. The best reduction for organic load reduction were obtained with hydraulic retention times (HRT) of 8.17 and 5.44 days with mean efficiencies of 89.8 and 90.9%, respectively.
