The increasing demand for sustainable products and services has become a constant requirement for the different stakeholders in an organization. Higher Education Institutions (HEI) have a crucial role in training conscious and competent professionals to lead these changes. Chemical analyses laboratories bring together the proper mix, where the adoption of mature and efficient management systems proves to be crucial not only to better train the institutions’ human resources but also to cooperate in recruiting research projects and other services to benefit society. Maturity models assist in the needed stages for sustainable growth to take place. This paper proposes a maturity model based on standardized norms to guide adjustments related to quality, risks, safety, and environment of chemical analyses laboratories in public higher education institutions. This research was done in four stages: theoretical research about maturity models, sustainability, and integrated management systems; survey with laboratories; case study at a chemical analyses laboratory of an HEI; and structuring and validating a maturity model. As the main results, it was observed that more than 80% of public laboratory managers believe it would be relevant to adopt a maturity model to help organize the laboratory’s internal and external processes. 86% of public laboratory managers understand that using management systems can contribute to hiring new services. We can also observe that 42.9% of public laboratory managers do not know any maturity model. As conclusion, the model includes eight dimensions, 31 subdimensions, and 204 management practices to assess and guide chemical analyses laboratories to sustainable maturity levels.

The objective of this study was to determine the seasonal distribution and gastrointestinal nematode parasite load in crossbred Santa Inês tracer lambs, and to correlate the rainfall during the study period with occurrences of parasitic infections. Sixty-four male tracer lambs between the ages of four and eight months were used in the study. Two tracer lambs were inserted into the herd every 28 days to determine the pattern of infective larvae available in the environment. Variation in the fecal egg count (FEC) of nematodes was observed at the study site, with many samples containing undetectable parasite loads during the dry season. The larvae identified in coprocultures wereHaemonchus sp., Trichostrongylus sp.,Cooperia sp., Strongyloides sp. andOesophagostomum sp. The nematodes recovered at necropsy were Haemonchus contortus, Trichostrongylus colubriformis, Cooperia punctata, C. pectinata, Trichuris sp.,Oesophagostomum sp. and Skrajabinema ovis. The total number of larvae and the total number of immature and adult forms recovered from the tracers showed seasonal distributions that significantly correlated with the amount of rainfall received that month (p value ≅ 0.000 in all cases ). The species H. contortus was predominant in the herd and should be considered to be main pathogenic nematode species in these hosts under these conditions.

The e-learning in Brazil has shown such intense development followed by its problems. Obstacles in the teaching learning permeate, among others, the use of virtual environments, production of teaching materials, pedagogical mediation, where the tutor has responsibility in these factors. In order to combine the use of technology with the nature of the pedagogical dimension, this theoretical essay discusses the concept of pedagogical usability from existing problems and presents explanations about the dimensions and criteria present in the literature.
