Carotenoids have attracted greater attention due to the beneficial role on human health. It is an essential nutrient and has some biological functions such as species-specific coloration, photoprotection, light absorbing, which is an important component because of its role as precursor of vitamin A. In this study was performed the production of fl-Carotene by Rhodotorula glutinis UCP/WFCC 1555 in presence and absence of blue and white using LED （light-emitting diodes） and evaluation of the cytotoxic effect. The production was investigated in low cost medium constituted by different concentrations of CG （crude glycerin） and CSL （corn steep liquor） from the CCD （Central Composite Design） and the identification and yield of the β-Carotene was investigated by chromatographic profile （HPLC）. Additionally, the fl-Carotene produced was tested to evaluate its cytotoxic effect in human tumor cells MCF-7 （breast cancer） and HL-60 （promyelocytic leukemia） and healthy cells of macrophages. The results showed that in the medium composed by 6% glycerin and 0.6% corn steep liquor, in the absence of light, occurred the maximum production of total carotenoids with values of 160μg·g-1 and these 100.60μg·g-1 correspond to the β-Carotene that showed ability in inhibit cell growth in several tumor cells such as MCF-7 cells （breast cancer） and HL-60 （promyelocytic leukemia）.

In the last decades, several indicators are showing the inadequacy of countries' economic models. Changes in these models are necessary to contemplate the concept of sustainable development. In this sense, the 17 Sustainable Development Goals were published by United Nations to guide companies, countries and people. Volunteer actions are important initiatives for this. This kind of initiative can be described as the act of helping someone, aiming to contribute to a fairer society in which charity and citizenship are present. The main objective of this study is to analyze the main aspects that influence Brazilian companies' employees to participate in volunteer programs and, to identify how these aspects may be grouped into factors. Initially, a bibliographic study was carried out to identify the main aspects that influence the participation of companies' employees in volunteer programs. With this information, a questionnaire was structured and used in a survey. Data analysis was performed via exploratory factor analysis (EFA) and five from seven aspects analyzed were validated. They are grouped into two factors named "personal aspects" and "institutional aspects". The first factor better explains the aspects mentioned. The results presented here may be useful for managers of volunteer programs and researchers interested in the theme.

Native plants from the Brazilian Amazon Biome are rich in nutrients, oils and fats and, therefore, represent a very important regional food resource. There is a global interest in the nutritional potential of tropical fruits, the potential of Amazonian fruits as source of essential fatty acids is still under exploited, since their composition is still understudied.1H Magnetic Resonance Nuclear (1H NMR) is a robust spectroscopic tool to profile fatty acids components in oils. The objectives of this work were to use1H NMR to determine the fatty acids profile and the physicochemical properties of crude oils and fats obtained from fruits of Brazilian Amazon: açaí, ata-brava, bacaba, buriti, buritirana, yellow murici, red murici, piaçaba braba, tucumanzinho, pupunha red and yellow varieties. Oils were obtained by Soxhlet extraction using hexane as a solvent. After solvent removal by rotoevaporation, the resulting oils and fats were analyzed by1H NMR spectroscopy. Unsaturated fatty acids oleic (?9), linoleic (?6) and linolenic (?3) acids were quantified in the oils and their physicochemical properties were determined. It was observed that the oils have predominately ?9 fatty acids, followed by ?6 and ?3 representatives. The physicochemical properties confirmed edibility and good quality of oils and fats present in the aforementioned Amazonian fruits. Copyright © 2018, AIDIC Servizi S.r.l.

Background Climate change is a problem which is global in nature, and whose effects go across a wide range of disciplines. It is therefore important that this theme is taken into account as part of universities ' teaching and research programs. Methods A three-tiered approach was used, consisting of a bibliometric analysis, an online survey and a set of case studies, which allow a profile to be built, as to how a sample of universities from 45 countries handle climate change as part of their teaching programs. Results This paper reports on a study which aimed at identifying the extent to which matters related to climate change are addressed within the teaching and research practices at universities, with a focus on the training needs of teaching staff. It consists of a bibliometric analysis, combined with an online worldwide survey aimed at ascertaining the degree of involvement from universities in reducing their own carbon footprint, and the ways they offer training provisions on the topic. This is complemented by a set of 12 case studies from universities round the world, illustrating current trends on how universities handle climate change. Apart from reporting on the outcomes of the study, the paper highlights what some universities are doing to handle climate issues, and discusses the implications of the research. Conclusions The paper lists some items via which universities may better educate and train their students on how to handle the many challenges posed by climate change.

& BULL;The objective of this article is to carry out a case study on the doctrinal princi-ples of corporatism supported by Brazilian jurist Francisco Jose de Oliveira Viana and by American economist and theologian John A. Ryan. It analyzes the influence of tenets of Catholic doctrine stated in papal encyclicals Rerum Novarum (1891) and Quadragesimo Anno (1931) in their ideas and the adequacy of their principles to the solution of economic and social problems faced during the Vargas and Roosevelt administrations. For this pur-pose, in addition to the encyclicals, we analyze the works Problemas de direito sindical and Direito do trabalho e democracia social by Oliveira Viana and A program of Social Reform by Legislation and Capital and Labor by Ryan.
