Training and Competition Readiness in Triathlon
Triathlon is characterized by the multidisciplinary nature of the sport where swimming, cycling, and running are completed sequentially in different events, such as the sprint, Olympic, long-distance, and Ironman formats. The large number of training sessions and overall volume undertaken by triathletes to improve fitness and performance can also increase the risk of injury, illness, or excessive fatigue. Short- and medium-term individualized training plans, periodization strategies, and work/rest balance are necessary to minimize interruptions to training due to injury, illness, or maladaptation. Even in the absence of health and wellbeing concerns, it is unclear whether cellular signals triggered by multiple training stimuli that drive training adaptations each day interfere with each other. Distribution of training intensity within and between different sessions is an important aspect of training. Both internal (perceived stress) and external loads (objective metrics) should be considered when monitoring training load. Incorporating strength training to complement the large body of endurance work in triathlon can help avoid overuse injuries. We explore emerging trends and strategies from the latest literature and evidence-based knowledge for improving training readiness and performance during competition in triathlon
Socio-Economic Status, Territory and Political Participation in Twenty-First-Century Mexico
This article is built on the reflections that the authors have had during their latest research on political participation in several municipalities of Mexico. Thus, based on the ethnographies conducted between 2006 and 2016, mainly in the town of Xico (Veracruz state), we set up as analyzing unities specific political interactions (including patronizing) among Mexican citizens within the five types recognized by Social Sciences: voting, campaigning, contacting political officials, working on public affairs and talking about politics. On this basis, we explore the articulation of the aforementioned interactions and, more specifically, of the roles adopted by the interacting citizens as identity markers linking these people in a highlighted way with a series of socio?economic and socio?territorial features, dimensions that, ultimately, turn out inseparable from the existing power relations in the local societies. In conclusion, we are of the opinion that, together with indicators of income, education, professional category or living nearby territory, it can be affirmed that the political behavior in Mexico is shown as both socio?economic indicator and socio?territorial belonging not because parties represent interests of class, but because there are well defined spheres of political behavior depending on the socio?economic stratum and the socio?territorial belonging of the individual
Spin-momentum locking from topological quantum chemistry: applications to multifold fermions
In spin-orbit coupled crystals, symmetries can protect multifold degeneracies
with large Chern numbers and Brillouin zone spanning topological surface
states. In this work, we explore the extent to which the nontrivial topology of
chiral multifold fermions impacts the spin texture of bulk states. To do so, we
formulate a definition of spin-momentum locking in terms of reduced density
matrices. Using tools from the theory of topological quantum chemistry, we show
how the reduced density matrix can be determined from the knowledge of the
basis orbitals and band representation forming the multifold fermion. We show
how on-site spin orbit coupling, crystal field splitting, and Wyckoff position
multiplicity compete to determine the spin texture of states near chiral
fermions. We compute the spin texture of multifold fermions in several
representative examples from space groups (207) and (198). We
show that the winding number of the spin around the Fermi surface can take many
different integer values, from zero all the way to . Finally, we
conclude by showing how to apply our theory to real materials using the example
of PtGa in space group .Comment: 28 pages, 6 figure
Responsible management of innovation in business
This chapter explores the concept and practice of responsible management of innovation. Responsible innovation is a key response to the grand challenges faced by society, helping to develop innovations with society in mind, and limit any unintended consequences. Responsible managers with influence over innovations need knowledge and understanding of how responsible innovation applies to their roles and how as individuals they can manage innovation responsibly. While the application of responsible innovation to these contexts faces a number of practical and conceptual challenges, this chapter will focus on the contribution and potential of responsible management of innovation processes to provide economic and societal benefits. This chapter explores these issues through the perspective of individual managers, at the level of the organisation and finally at the level of the innovation system
Real clocks and the Zeno effect
Real clocks are not perfect. This must have an effect in our predictions for
the behaviour of a quantum system, an effect for which we present a unified
description encompassing several previous proposals. We study the relevance of
clock errors in the Zeno effect, and find that generically no Zeno effect can
be present (in such a way that there is no contradiction with currently
available experimental data). We further observe that, within the class of
stochasticities in time addressed here, there is no modification in emission
lineshapes.Comment: 12 a4 pages, no figure
Combination of polymeric superplasticizers, water repellents and pozzolanic agents to improve air lime-based grouts for historic masonry repair
This paper presents the experimental procedure to develop air lime-based injection grouts including polymeric superplasticizers, a water repellent agent and pozzolanic agents as additives. Research focuses on the development of grouts to improve various characteristics simultaneously combining different additions and admixtures. Aiming to improve the injectability of the grouts, in this study different polymeric superplasticizers were added, namely polycarboxylated-ether derivative (PCE), polynaphthalene sulfonate (PNS) and condensate of melamine-formaldehyde sulfonate (SMFC). Sodium oleate was also used as a water repellent agent to reduce the water absorption. The enhancement of the strength and setting time was intended by using microsilica and metakaolin as pozzolanic mineral additions. Compatibility between the different admixtures and action mechanism of the different polymers were studied by means of zeta potential and adsorption isotherms measurements. Diverse grout mixtures were produced and investigated assessing their injectability, fluidity, stability, compressive strength, hydrophobicity and durability. This research leads to several suitable mixtures produced by using more than one component to enhance efficiency and to provide better performance of grouts. According to the results, the grout composed of air lime, metakaolin, sodium oleate and PCE was found the most effective composition improving the mechanical strength, injectability and hydrophobicity
Quantum evolution according to real clocks
We characterize good clocks, which are naturally subject to fluctuations, in
statistical terms. We also obtain the master equation that governs the
evolution of quantum systems according to these clocks and find its general
solution. This master equation is diffusive and produces loss of coherence.
Moreover, real clocks can be described in terms of effective interactions that
are nonlocal in time. Alternatively, they can be modeled by an effective
thermal bath coupled to the system.Comment: RevTeX 3.01, 6 page
