Abstract:
Abstract Rheology of wood molecular and supramolecular organization has mostly been conducted with dynamic methods, and the application of time/temperature equivalence typically requires plasticizers to observe segmental relaxation. Dry wood rheology offers the experimental advantage of easy moisture control, but only weak secondary relaxations are observed with dynamic methods. Static methods allow for the longer relaxation times in glassy polymers, and these relaxations are strongly stimulated by lower less damaging temperatures. This study describes the application of creep mode time/temperature equivalence to dry yellow-poplar (Liriodendron tulipifera) and southern yellow pine (Pinus spp.). It was found that time/temperature equivalence was valid from 10–170°C, but only for specimens that received a prior 30-min thermal treatment (with minor desiccation) in the range of 100–170°C. The two woods exhibited clear differences in the temperature dependence of the dry wood creep relaxation, and in the sensitivity to free volume manipulation. These findings are believed to reflect polymer structural differences in hardwoods and softwoods indicating that creep mode time/temperature studies of dry wood may be useful for the analysis of xylem polymer behavior.

Abstract:
The relaxation time scales in a commercial-grade Zr41.25Ti13.75Ni10Cu12.5Be22.5 (at.%) bulk metallic glass were examined using transient and dynamic mechanical experiments. The viscoelastic and sub-Tg relaxations were well described by the Kohlrausch–Williams–Watts relaxation function. A large activation energy (4.0 eV) and small nonexponentiality parameter (approximately 0.5) were observed for viscoelastic relaxation above Tg consistent with the cooperative nature of atomic movements leading ultimately to viscous flow. Conversely, a small activation energy (0.1 eV) and large nonexponentiality parameter (approximately 0.9) were observed for the sub-Tg relaxation suggesting localized atomic adjustments which may involve different structural units or mechanisms. The glass transition was manifested as a decoupling of the sub-Tg and viscoelastic relaxation. The resulting transition temperature determined at a selected time scale was in agreement with the value obtained from calorimetric studies.

Abstract:
The Bhatnagar–Gross–Krook (BGK) single-relaxation-time collision model for the Boltzmann equation serves as the foundation of the lattice BGK (LBGK) method developed in recent years. The description of the collision as a uniform relaxation process of the distribution function towards its equilibrium is, in many scenarios, simplistic. Based on a previous series of papers, we present a collision model formulated as independent relaxations of the irreducible components of the Hermite coefficients in the reference frame moving with the fluid. These components, corresponding to the irreducible representation of the rotation group, are the minimum tensor components that can be separately relaxed without violating rotation symmetry. For the 2nd, 3rd and 4th moments, respectively, two, two and three independent relaxation rates can exist, giving rise to the shear and bulk viscosity, thermal diffusivity and some high-order relaxation process not explicitly manifested in the Navier–Stokes-Fourier equations. Using the binomial transform, the Hermite coefficients are evaluated in the absolute frame to avoid the numerical dissipation introduced by interpolation. Extensive numerical verification is also provided. This article is part of the theme issue ‘Progress in mesoscale methods for fluid dynamics simulation’.

Abstract:
Tissue-level stress-relaxation of ligaments and tendons in the toe region is characterized by fast and long-term relaxations and an increase in relaxation magnitude with strain. Characterizing the compositional and structural origins of these phenomena helps in the understanding of mechanisms of ligament and tendon function and adaptation in health and disease. A three-step tensile stress-relaxation test was conducted on dumbbell-shaped pieces of bovine knee ligaments and patellar tendon (PT) ( n = 10 knees). Their mechanical behaviour was characterized by a fibril-reinforced poroviscoelastic material model, able to describe characteristic times and magnitudes of fast and long-term relaxations. The crimp angle and length of tissues were measured with polarized light microscopy, while biochemical contents were determined by colorimetric biochemical methods. The long-term relaxation time was longer in the anterior cruciate ligament (ACL) and PT compared with collateral ligaments ( p < 0.05). High hydroxyproline content predicted greater magnitude and shorter time of both fast and long-term relaxation. High uronic acid content predicted longer time of long-term relaxation, whereas high crimp angle predicted higher magnitude of long-term relaxation. ACL and PT are better long-term stabilizers than collateral ligaments. The long-term relaxation behaviour is affected or implied by proteoglycans and crimp angle, possibly relating to slow structural reorganization of the tissue.

Abstract:
We developed and evaluated objective manometric criteria that define transient lower esophageal sphincter (LES) relaxation. In 23 normal subjects and 9 patients with gastroesophageal reflux disease, systematic analysis of swallow-induced LES relaxation showed that dry swallows preceded LES relaxation by a median of 1.4 s. The relaxation rate was always > 1 mmHg/s, the relaxation nadir always occurred within 7 s, and the duration of relaxation was < 9 s. During concurrent esophageal manometry and pH monitoring, 104 reflux episodes associated with a LES pressure fall that was not related to swallowing were identified and the pressure falls classified as transient LES relaxations or not by visual recognition. LES pressure was always < or = 2 mmHg at time of reflux, and relaxation was significantly longer than for swallow-induced LES relaxation. Of 88 pressure falls classified visually as transient LES relaxations, 90% reached nadir pressure within 7 s at a rate of > 1 mmHg/s. Sixteen pressure falls were classified as a gradual downward drift in LES pressure, which in 15 cases was < 1 mmHg/s. Based on the analysis, transient LES relaxation can be defined by 1) absence of swallowing for 4 s before to 2 s after the onset of LES relaxation, 2) relaxation rate of > or = 1 mmHg/s, 3) time from onset to complete relaxation of < or = 10 s, and 4) nadir pressure of < or = 2 mmHg.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract:
The long time relaxation behavior of linear and long chain branched (LCB) metallocene polyethylene (mPE) is very important for understanding their flow properties. One linear and four LCB mPEs were studied in shear creep and recovery measurements. All the mPEs have similar molecular weight and molecular weight distribution but different levels of long chain branching. A technique was developed to eliminate the effect of non-ideal start-up at the beginning of creep experiment and the small residual stress that exists during the creep recovery period. It is found that the existence of long chain branching is responsible for the increasing of the zero shear viscosity, the steady state compliance and the longest relaxation time. The retardation and relaxation spectrums were calculated from the creep compliance. The dynamic compliance calculated using retardation spectrum is compared with that measured directly. Both are in very good agreement. These observations are compared with the molecular dynamics theory.

Abstract:
Background Physics-based snow simulation in real time is an unexplored area, the reason being the difficulty introduced by the multitude of factors that affect the snow behaviour, such as cohesion, thermodynamics, and compression. Simulating snow in real time when considering these factors can become computationally demanding. However, the continued advancement of graphics processing units makes the exploration of real-time snow simulation attractive. Recently published research on real time physics-based snow simulation shows promising results in a parallel solution and will serve as motivation and base for this thesis. Objectives This thesis aims to improve the time-step of a previously proposed method using an iterative method and improve the snow behaviour with a particle-based boundary handling implementation. The aim consists of the following objectives. Integrate an iterative method, extend the snow behaviour with additional snow types, and implement a particle-based boundary handling method with two-way coupling. The proposed method should remain comparable to the original method in terms of snow behaviour. In order to gather results, the methods are measured in performance and used in a questionnaire to analyse the behaviour. Methods An iterative method along with a particle-based boundary handling method is implemented. The methods are both measured and compared using quantitative tests. Additionally, a questionnaire is deployed to gather qualitative results about the behaviour of the snow. Results The proposed method outperforms the original method in terms of time-step size. The proposed method is capable of increasing the time-step tenfold while decreasing the execution time by approximately eight times. Finally, the results from the questionnaire verify the perceived naturalism of the snow and its comparability to the original method. Conclusions The proposed method can perform with an increased time-step and a lower execution time compared to the original method, at the cost of time spent per frame. Lastly, the snow is perceived as natural with the boundary handling method at a significance level of 1 %.
Bakgrund Fysikbaserad snösimulering i realtid är ett outforskat område, anledning till detta är mängden faktorer som påverkar snö, exempelvis sammanhållning, termodynamik och kompression. Simulering av snö i realtid som tar hänsyn till dessa faktorer kan bli beräkningsmässigt krävande, däremot har den växande utvecklingen av grafikprocessorer gjort utforskning av realtidsmetoder ytterligare attraktivt. Nyligen publicerad forskning inom fysikbaserade snösimuleringar i realtid visar lovande resultat i en parallell lösning och kommer att användas som motivering samt bas i detta examensarbete. Syfte Detta examensarbete syftar till att förbättra tidsstegen i en tidigare implementerad metod med hjälp av att använda ett iterativt tillvägagångssätt samt förbättra snöbeteendet med en partikelbaserad gränshanteringsimplementation. Syftet är uppdelat i följande mål. Integrera en iterativ metod, utöka snöbeteendet med ytterligare snötyper, och implementera en partikelbaserad gränshanteringsmetod med tvåvägskoppling. Den föreslagna metoden ska förhålla sig jämförbar med originalmetoden med avseende på snöbeteendet. Slutligen för att samla in resultat mäts metoderna i prestanda och dessutom används ett frågeformulär för att analysera beteendet. Metod En iterativ metod tillsammans med en partikelbaserad gränshanteringsmetod är implementerad. Båda metoderna mäts och jämförs med hjälp av kvantitativa tester. Dessutom distribueras ett kvalitativt frågeformulär för att samla resultat om snöns beteende.  Resultat Den föreslagna metoden tillåter större tidsteg än originalmetoden. Den iterativa metoden är kapabel till att förstora tidsstegen tiofaldigt, samtidigt som den sänker exekveringstiden till en åttondel. Resultaten verifierar den uppfattade naturligheten av snön och jämförelsebarheten till originalmetoden. Slutsatser Den föreslagna metoden kan prestera med ett större tidssteg och en lägre exekveringstid jämfört med originalet i utbyte av högre tid spenderad per bildruta. Slutligen uppfattas snön som naturlig i sammankoppling med gränshanteringsmetoden vid en signifikansnivå på 1 %.

Thus it was established that ion bombardment of silicon surface in the energy region of the threshold of elastic displacement of atoms might allow to improve structural characteristics of surface lavers and to decrease the relaxation time. Energy dependencies of radiation induced processes show a possibility to improve the real staicture of Silicon surface and to accelerate the long-term surface relaxation in microelectronic technology.

Abstract:
The article presents varieties and variants of relaxation techniques advisable to use after intense physical exertion. The concept of "relaxation" and understanding of its role in physical education to maintain health and harmonious development of youth are considered. Considering the fact that one of the main trends in sports remains the increase in the intensity of training and the need to improve the results of competitions, the problem of restoring the athlete's performance capacity after physical exertion is extremely relevant today. Understanding the causes of fatigue and the physiological mechanisms of recovery, control over the relevant processes, the rational use of modern methods of body relaxation and means of recovery are important for assessing the impact of physical stress on the body, the effectiveness of training programs, identifying overtraining, determining the optimal rest time after physical exercises, and therefore, are necessary to improve the athlete's training and achieving high results.

Abstract:
We have applied molecular dynamics method and semi-empirical potential [1] to obtain the realistic picture of Si surface layers relaxation.The starting configuration was taken as a parallelepiped containing 864 atoms. There were 12 layers with 72 atoms in each one. Periodic boundary conditions were used in two dimensions. At first all atoms were in normal lattice positions. The relaxation of Si surface, which corresponds to (001) plane was investigated. MD method was applied in its standard form i.e. the equations of motion were solved by using of the central difference scheme. The time-step was 10-14s.

Abstract:
Review question / Objective: To conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the effect of lower-dose sugammadex using IBW or CBW as dosing scalars, with that of standard-dose sugammadex based on TBW, on reversal time, defined as time to recovery of train of four ratio (TOFR) ≥ 0.9, among morbidly obese people after moderate or deep NMB with either rocuronium or vecuronium. Eligibility criteria: We included only randomized controlled trials (RCTs) that compared TBW with other dosing scalars for sugammadex. Studies not published in full text articles or in languages other than English were excluded. Trials that included patients above 18 years of age and BMI more than or equal to 40 who underwent general anaesthesia with any degree of NMB induced by either rocuronium or vecuronium. Trials that evaluated TBW and other dosing scalars for sugammadex were included. We included trials that compared TBW with any other dosing scalars for sugammadex. Trials that did not include dosing based on TBW as one arm in the comparison were excluded.

Fuentes, Nelson, Gonzalo Aguilar, and Camila Trillos. Impact of the COVID-19 Pandemic on the Formal Labor Market and the Pension System in El Salvador. Inter-American Development Bank, November 2022. http://dx.doi.org/10.18235/0004523.

Abstract:
Using an impact evaluation methodology for interrupted time-series and the IDB Pension Projection Model, this study estimates that the COVID-19 pandemic could have notably effects on the private pension system in El Salvador as a consequence of the relaxation of requirements to repay early withdrawals that was established in the context of the pandemic. This fact could negatively affect passive coverage rate, system incomes, short-run system surplus and replacement rates, generating an increase in the fiscal cost. The problems of the Salvadoran pension system are structural, and the COVID-19 pandemic has exacerbated them. Consequently, although it is possible to discuss policies to reduce these effects, it is necessary to frame this discussion in the context of a comprehensive reform of the system.
