Chinese Entrepreneurship in Portugal: the traditional ethnic strategies?
Although immigrant entrepreneurial activities have always been present in Europe three historical circumstances rendered them more visible in recent decades The increase in immigration flows and the concentration of immigrants in urban contexts stimulated the creation of a different type of demand associated with immigrant communities Also the economic growth and expansion of several markets during the 1950s and 1960s produced a decline in native small and medium enterprises leaving opportunities for immigrants in certain traditional sectors Finally the oil crisis in 1973 74 had substantial impacts in terms of the increase in immigrant unemployment Within this framework immigrants found in entrepreneurship an alternative to economic integration in European societies They were therefore responsible for the increase in rates of entrepreneurship between 1970 and 1980 Light and Rosenstein 1995 12-13 Waldinger et al 1990 8
Constant depth microfluidic networks based on a generalised Murray’s law for Newtonian and power-law fluids
This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.Microfluidic bifurcating networks of rectangular cross-sectional channels are designed
using a novel biomimetic rule, based on Murray’s law. Murray’s principle is extended to
consider the flow of power-law fluids in planar geometries (i.e. of constant depth rectangular
cross-section) typical of lab-on-a-chip applications. The proposed design offers the ability to
control precisely the shear-stress distributions and to predict the flow resistance along the network.
We use an in-house code to perform computational fluid dynamics simulations in order
to assess the extent of the validity of the proposed design for Newtonian, shear-thinning and
shear-thickening fluids under different flow conditions
Music as living heritage
What is cultural heritage, and why has it received so much public interest in recent years? Almost three decades after the World Organization UNESCO defined and established international recognition of Cultural and Natural Heritage sites and devised ways of protecting them, a completely new approach to cultural heritage emerged with the UNESCO
Convention for the Safeguarding of the Intangible Cultural Heritage in 2003. This global agreement for the maintenance, protection and dissemination of cultural manifestations and achievements that are not tangible objects or immobile monuments, like previous items classified as World Heritage, was a remarkable milestone of international cultural politics. This new understanding of cultural heritage owes much to representatives from Asian, African, and Latin American countries. In fact, just a few years after the promulgation of the 2003 Convention, the world cultural heritage map had already lost much of its European predominance. Asian countries such as China, Japan, South Korea, and India very soon showed up with lists of manifestations of their centenary (in some cases even millenary) national cultural heritages

BUSINESS MEDIATION IN BRAZIL:KEY REGULATORY CHALLENGES
What are the regulatory barriers, pitfalls, and challenges in Brazilian business mediation? In this article, we investigated the Brazilian Mediation Law no.13.140/15, to provide scholars, mediators, and other practitioners with a wide view on the legal issues involving the Brazilian Mediation Law, through an extensive literature review on the regulatory aspects of the Alternative Dispute Resolution, regarding the aforementioned Law. Case analysis and further implications are presented. Finally, conclusion and future research recommendations compile the present study
English Teaching in Cyberculture: A Brief Analysis
The present study aimed to comparatively analyze the potential of BBC Learning English and Memrise platforms, in inclusive English teaching. This is a qualitative-interpretative research based in exploratory approach which methodological-theoretical framework is anchored to the Bakhtinian dialogic language conception, to the second language acquisition theory to the Computer-Assisted Language Learning theory), to multiliteracies; and to the English use as a Lingua Franca. For the analysis, we have built a matrix based on the English language acquisition context. The analysis steps ran through the evaluation matrix building, the exploration and development of a comparative study of BBC learning and Memrise platforms on the defined parameters. To the parameters building, the linguistic, methodological, and accessibility aspects in the websites were considered. After analyzing BBC learning English and Memrise, it was identified that they do not encompass dialogical language acquisition and the concept of multiliteracies
Ischemic Preconditioning Improves the Bench-Press Maximal Strength in Resistance-Trained Men
International Journal of Exercise Science 16(4): 217-229, 2023. We investigated whether acute ischemic preconditioning (IPC) would affect upper limb maximal strength performance in resistance-trained men. Using a counterbalanced randomized crossover design, fifteen men (29.9 ± 5.9 yrs.; 86.3 ± 9.6 kg; 8.0 ± 5.0 yrs. resistance training experience) performed one-repetition maximum (1-RM) bench press tests on three different occasions: control, 10 min post-IPC or 10 min post-placebo (SHAM). One-way analysis of variance showed that the post-IPC condition increased (P \u3c 0.0001) 1-RM loads compared to both control and post-SHAM (control 113.3 ± 15.9 kg vs. SHAM 113.9 ± 15.8 kg vs. IPC 115.7 ± 15.6 kg), while control and SHAM did not differ (P \u3e 0.05). Individual results showed that 13 participants (~87%) improved their performance post-IPC compared to control, and 11 participants (~73%) performed better post-IPC compared to post-SHAM. Reported session rating of perceived exertion (RPE) was lower (P \u3c 0.0001) post-IPC (8.5 ± 0.6 arb.u) compared to control (9.3 ± 0.5 arb.u) and post-SHAM (9.3 ± 0.5 arb.u). Therefore, we conclude that IPC acutely improves upper limb maximal strength performance and reduces session-RPE in resistance-trained men. These results suggest an acute ergogenic effect of IPC for strength and power sports such as powerlifting
27 de novembro - Dia Nacional de Combate ao Câncer
O Dia Nacional de Combate ao Câncer foi instituĂdo pelo MinistĂ©rio da SaĂşde, por meio da Portaria n2 707, de 07 de dezembro de 1988, com o objetivo de evocar a importância histĂłrica das entidades de combate ao câncer, de consagrar os serviços que elas tĂŞm prestado ao Brasil e de proporcionar a mobilização popular para os aspectos educativos e sociais do combate ao câncer
Operationalization and Automation for Urban Management of Large Cities: Proposed Model and Case Study of the Operationalization Center in Rio de Janeiro (Brazil)
The cities require new elements to its management. The broad use of new information technology and communication (ICTs) are an alternative for improving the management of cities. The objective of this paper is to propose a model of operationalization center and urban automation for large cities to optimize the management of the city. The proposed model combines an operationalization Center, for managing the day to day of large cities, supported by technological and informational resources, combined with automation of urban equipments. The case study was conducted in the city of Rio de Janeiro (Brazil), mainly using the technique of semi-structured interview combined with documental research. As a result of this research, it is emphasized that the operationalization center contributes to the optimization of day to day management of the city, mainly by the integration of actions of various organizations involved in the management of the city studied
