Sheep grazing preferences on pastures in the Montado: effect of soil amendment ...
Carreira, Emanuel; Serrano, João; Silva, F.; Gomes, C.; Castro, J.; Carvalho, M.; Pereira, A.The aim this study was to evaluate the effect of dolomitic limestone application (uncorrected, U and corrected, C) and two sheep grazing systems (continuous, CG and deferred, DG) in preferred grazing areas, in natural pastures. The stocking rate was of 7 sheep/ha in CG and 16 sheep/ha in DG. In 4 plots of 1ha each, four treatments were constituted: T1 (UCG); T2 (UDG); T3 (CDG); and T4 (CCG). The study was carri...
Gestão de pastagens no Montado com diferentes sistemas de pastoreio: Impacto na...
Carreira, Emanuel; Serrano, João; Silva, F.; Gomes, C.; Castro, J.; Carvalho, M.; Pereira, A.O Montado/Dehesa é um ecossistema agro-silvo-pastoril característico da região sudeste da Península Ibérica. A gestão das pastagens neste ecossistema é complexa, devido às interações entre estas e o solo, as árvores, os animais em pastoreio e o clima. As preferências alimentares dos ovinos em pastoreio podem ser influenciadas por fatores como a altitude das parcelas, o encabeçamento animal, a disponibilidade de...
Breeding in bread-making wheat varieties for Mediterranean climate: The need to...
Maçãs, B.; Costa, R.; Gomes, C.; Bagulho, A.; Pinheiro, N.; Moreira, J.; Costa, A.; Patanita, Manuel; Dores, José Manuel de JesusIntroduction: Being one of the “big three” most cultivated cereals in the world, wheat plays a crucial role in ensuring global food/nutrition security, supplying close to 20% of the global needs for calories and proteins. However, the increasingly large fluctuations between years in temperatures and precipitation due to climate change cause important variations in wheat production worldwide. This fact makes whe...
Asdas responses in patients with axial spondyloarthritis starting bdmards: resu...
Santos, M. E.; Ramiro, S.; Van der Heijde, D.; Landewé, R.; Santos, F. Pimentel; Machado, A. R. Cruz; Ferreira, C.; Gomes, C.; Soares, C. DantasASAS and EULAR recommend the use of an improvement ≥1.1 in ASDAS at 12 weeks to determine the continuation of a bDMARD. However, it is debated whether improvements can occur and whether patients’ characteristics influence (time to) response.
The role of satisfaction with the performance appraisal: A comparative study be...
Rodrigues, R.; Gomes, C.; Junça Silva, A.Purpose – To study in Portugal (a) whether satisfaction with the performance appraisal (PA) differs depending on the sector where the workers perform their functions (private versus public), and (b) whether the relationship between workers’ perception of usefulness and accuracy of the performance appraisal process (PAP) and satisfaction with the outcome of their last PA is mediated by their satisfaction with th...
Bone density and proximal support effects on dental implant stability - finite ...
Gomes, C.; Mesnard, M.; Ramos, A.Objectives: The application of dental implants presents the occurrence of implant failures associated with bone proximal support. This study aims to assess implant behavior, in particular implant stability and strain distribution in the bone at different bone densities, and the effect of proximal bone support. Material and methods: Three bone densities (D20, D15, and D10) were considered in the experimental in ...
Employability profiles of higher education graduates: a person-oriented approach
Monteiro, S.; Almeida, L. S.; Gomes, C.; Sinval, J.Theoretical and empirical literature developed over recent years supports the concept of employability as a construct combining complex interactions of individual and contextual dimensions. This study aimed to identify differentiated profiles in graduates, combining personal and contextual variables related to employability. For this, 182 graduates from a public university were surveyed about their sociodemogra...
The role of dogs in the relationship between telework and performance via affec...
Junça Silva, A.; Almeida, M.; Gomes, C.Although there is evidence that pets may help individuals facing significant daily stressors, and that they may enhance the well-being of their owners, little is known about the benefits of pets for job performance. Since the COVID-19 pandemic crisis, teleworking was a strategy implemented in many countries to reduce the virus widespread and to assure organizational productivity. Those who work from home and wh...
