Dynamic properties of polyurethane from resonant column tests for numerical GSI study
Authors: Gatto Michele Placido Antonio , Lentini Valentina , Montrasio Lorella 
Published: May 2022

AbstractThe paper focuses on the detailed analysis of the dynamic characterisation of polyurethane to evaluate the effects of polyurethane injections into soil with the aim of geotechnical seismic isolation. To determine the dynamic properties, resonant column (RC) tests were performed at the University Kore of Enna (Italy) on specimens of pure polyurethane with different values of density and subjected to different mean confining pressures. The results obtained by means of RC tests, in terms of shear modulus G and the damping ratio D as a function of shear strain γc, allowed to develop an analytical formulation for G-γc and D-γc curves, taking into account the linear relationship with density, of both the maximum value of shear modulus Gmax and the minimum value of damping ratio Dmin. The analytical formulation derived from the experimental results is applied for ground response seismic analyses of cohesive soils injected with polyurethane, using a finite element code. The numerical results show that the polyurethane injections reduce the value of maximum acceleration on the ground surface and the reduction varies with the thickness of the soil modified by polyurethane injections.

AbstractThis study aimed to measure the thermal effusivity distribution on a lunar regolith simulant (FJS-1) using a thermal microscope and to calculate the average thermal effusivity and thermal conductivity using density and specific heat. Moreover, discussions were conducted based on the results of the microstructural analysis of the sample. The FJS-1 particles were embedded in an epoxy resin and polished to a mirror finish. The samples were analyzed using scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy (SEM–EDS). X-ray diffraction (XRD) was performed to identify the mineral phases in FJS-1. The results of SEM–EDS and XRD showed that a single sand particle was composed of several minerals, such as anorthite and olivine. Then, the thermal microscope was used to obtain the distribution of the thermal effusivity of a particle from the mirror-finished sample in a 1 × 1 mm2area with intervals of 10 μm. The measured thermal effusivity correlates with the SEM image of the sample. Anorthite has a small thermal effusivity of 1.99 ± 0.31 kJ·s−0.5·m−2·K−1, while olivine has a large thermal effusivity of 2.73 ± 0.35 kJ·s−0.5·m−2·K−1. In both cases, the thermal effusivity was found to be of the same order of magnitude as the reported values. The average thermal effusivity and conductivity of a single particle were determined to be 2.4 ± 0.6 kJ·s−0.5·m−2·K−1and 2.6 ± 1.3 W m−1·K−1, respectively, based on the proportion of existing phases.
The combinatorics of weight systems and characteristic polynomials of isolated quasihomogeneous singularities
Authors: Hertling Claus , Mase Makiko 
Published: May 2022

AbstractA paper of the first author and Zilke proposed seven combinatorial problems around formulas for the characteristic polynomial and the exponents of an isolated quasihomogeneous singularity. The most important of them was a conjecture on the characteristic polynomial. Here, the conjecture is proved, and some of the other problems are solved, too. In the cases where also an old conjecture of Orlik on the integral monodromy holds, this has implications on the automorphism group of the Milnor lattice. The combinatorics used in the proof of the conjecture consists of tuples of orders on sets $$\{0,1,\ldots ,n\}$$

Ethical Values in a Post-Industrial Economy: The Case of the Organic Farmers’ Market in Granada (Spain)
Authors: Vázquez Alfredo Macías , del Moral José Antonio Morillas 
Published: May 2022

AbstractThe importance of the collective management of immaterial resources is a key variable in the valorisation of products in a post-industrial economy. The purpose of this paper is to analyse how, in post-industrial economies, it is possible to devise alternative forms of mediation between producers and consumers, such as organic farmers' markets, to curb the appropriation of rent by transnational and/or local business elites from the value created by immaterial resources. More specifically, we analyse those aspects of the collective management of ethical values that, in the case of organic farmers' markets, can be a strategic source of competitive advantage for local producers. In this paper, the Ecomercado de Granada is studied as an example of mediation between production and consumption in a post-industrial economy.
A “stick to beat you with”? Advocating for a Critical Close Reading of ‘Vocation’ Among Evangelical Medics in England
Authors: Riley Jennifer 
Published: May 2022

AbstractEvangelical Christianity and healthcare work are two contexts in which vocation is often an important discourse. Exploring uses, understandings and implications of vocation for evangelical medics thus offers a rich opportunity to critically interrogate vocation from two important perspectives. In addition to identifying a three-tiered construction of vocation, on macro-, meso- and micro-levels, this paper suggests that to fully understand its manifestations among a sample of English evangelical medics, a critical, Weberian-style reading is valuable. This latter conclusion resonates with those drawn by scholars who extend a critical view across constructions of medical vocation more broadly, not least given concerns regarding workplace burnout.

Data-driven modeling of CO2 emission-allowance compensation for wood-purchasing optimization toward carbon–neutral forest industry
Authors: Palander Teijo , Takkinen Jari 
Published: May 2022

AbstractThe faster market changes of EU’s CO2 emission allowance price have increased operation challenges in wood supply of forest industry. The objectives of this study are to present basics of its data-driven modeling for purchasing renewable forest wood. Particularly, the effects of the changes in prices and available carbon sink are considered in management of wood purchasing at the level of the local districts. Two scenarios described procurement situations in non-renewable carbon sinks. The results were compared to the scenario in renewable carbon sink of carbon–neutral forestry. Time-varying emission-allowance parameters of models affected wood purchase and deliveries in the districts. Therefore, cost efficiency of wood-supply operations, as well as the utilization rate of renewable wood resources, can be optimized by data-driven dynamic wood-flow models in digitalized decision support. In addition, the results testify that the model optimizes wood purchasing in the districts at the way of CO2 emission allowance market. Therefore, by using the model wood-supply operations could be optimized toward carbon neutrality, which is important success factor of forest industry.

Abstract
Background
The Philippines has recommended the use of Quality-Adjusted Life Years (QALYs) in government health technology assessments (HTA). We aimed to develop a value set for the EQ-5D-5L based on health preferences of the healthy general adult population in the Philippines.

Methods
Healthy, literate adults were recruited from the Philippine general population with quota targets based on age, sex, administrative region, type of residence, education, income, and ethnolinguistic groups. Each participant’s preference was elicited by completing Composite Time Trade-Off (C-TTO) and Discrete Choice Experiment (DCE) tasks. Tasks were computer-assisted using the EuroQol Valuation Technology 2.0. To estimate the value set, we explored 20- and 8-parameter models that either use c-TTO-only data or both c-TTO and DCE (also called hybrid models). Final model choice was guided by principles of monotonicity, out-of-sample likelihood, model fit, and parsimony.

Results
We recruited 1000 respondents with demographic characteristics that approximate the general population such as 49.6% Female, 82% Roman Catholic, 40% in urban areas, and 55% finished high school. None of the 20-parameter models demonstrated monotonicity (logical worsening of coefficients with increasing severity). From the 8-parameter models, the homoscedastic TTO-only model exhibited the best fit. From this model, mobility and pain/ discomfort had the highest effect on utilities.

Conclusion
The selected model for representing the Philippine general population preferences for EQ-5D-5L health states was an 8-parameter homoscedastic TTO-only model. This value set is recommended for use in QALY calculations in support of HTA-informed coverage decisions in the Philippines.
Reversing logical nihilism
Authors: Haze Tristan Grøtvedt 
Published: May 2022

AbstractGillian Russell has recently proposed counterexamples to such elementary argument forms as Conjunction Introduction (e.g. ‘Snow is white. Grass is green. Therefore, snow is white and grass is green’) and Identity (e.g. ‘Snow is white. Therefore, snow is white’). These purported counterexamples involve expressions that are sensitive to linguistic context—for example, a sentence which is true when it appears alone but false when embedded in a larger sentence. If they are genuine counterexamples, it looks as though logical nihilism—the view that there are no valid argument forms—might be true. In this paper, I argue that the purported counterexamples are not genuine, on the grounds that they equivocate. Having defused the threat of logical nihilism, I argue that the kind of linguistic context sensitivity at work in Russell’s purported counterexamples, if taken seriously, far from leading to logical nihilism, reveals new, previously undreamt-of valid forms. By way of proof of concept I present a simple logic, Solo-Only Propositional Logic (SOPL), designed to capture some of them. Along the way, some interesting subtleties about the fallacy of equivocation are revealed.
CYB5R3 overexpression preserves skeletal muscle mitochondria and autophagic signaling in aged transgenic mice

Published: May 2022

Abstract
Cytochrome b5 reductase 3 (CYB5R3) overexpression activates respiratory metabolism and exerts prolongevity effects in transgenic mice, mimicking some of the salutary effects of calorie restriction. The aim of our study was to understand how CYB5R3 overexpression targets key pathways that modulate the rate of aging in skeletal muscle, a postmitotic tissue with a greater contribution to resting energy expenditure. Mitochondrial function, autophagy and mitophagy markers were evaluated in mouse hind limb skeletal muscles from young-adult (7 months old) and old (24 months old) males of wild-type and CYB5R3-overexpressing genotypes. Ultrastructure of subsarcolemmal and intermyofibrillar mitochondria was studied by electron microscopy in red gastrocnemius. CYB5R3, which was efficiently overexpressed and targeted to skeletal muscle mitochondria regardless of age, increased the abundance of complexes I, II, and IV in old mice and prevented the age-related decrease of complexes I, III, IV, and V and the mitofusin MFN-2. ATP was significantly decreased by aging, which was prevented by CYB5R3 overexpression. Coenzyme Q and the mitochondrial biogenesis markers TFAM and NRF-1 were also significantly diminished by aging, but CYB5R3 overexpression did not protect against these declines. Both aging and CYB5R3 overexpression upregulated SIRT3 and the mitochondrial fission markers FIS1 and DRP-1, although with different outcomes on mitochondrial ultrastructure: old wild-type mice exhibited mitochondrial fragmentation whereas CYB5R3 overexpression increased mitochondrial size in old transgenic mice concomitant with an improvement of autophagic recycling. Interventions aimed at stimulating CYB5R3 could represent a valuable strategy to counteract the deleterious effects of aging in skeletal muscle.

Influence of a Partial Substitution of Co by Fe on the Phase Stability and Fatigue Behavior of a CoCrWC Hard Alloy at Room Temperature
Authors: Brackmann Lukas , Schuppener Jannik , Röttger Arne , Weber Sebastian 
Published: May 2022

Abstract
The deformation-induced phase transition from fcc to hcp causes local embrittlement of the metal matrix in Cobalt-base alloys, facilitating subcritical crack growth under cyclic loading and reducing fatigue resistance. Our approach to increasing the fatigue life of Co-based hard alloys is to suppress the phase transition from fcc to hcp by an alloy modification that increases the stacking fault energy (SFE) of the metal matrix. Therefore, we substitute various contents (15, 25, and 35 mass pct) of Co by Fe and analyze the effect on the fatigue life and resistance against subcritical crack growth. Subcritical crack growth in the specimens takes place in a cyclic load test. The proceeding crack growth and the occurrence of phase transformations are monitored by scanning electron microscope (SEM) investigations and electron backscatter diffraction (EBSD). We determined an SFE of 35 mJ/m2 at an iron content of 35 mass pct, which leads to a change of the main deformation mechanism from deformation-induced martensitic transformation to deformation twinning. Analysis of cyclically loaded specimens revealed that the resistance against subcritical crack growth in the metal matrix is facilitated with increasing Fe content, leading to a significant increase in fatigue life.

AbstractAlthough the effects of malnutrition on morbidity and mortality in adult patients undergoing allogeneic hematopoietic stem cell transplantation are clear, the relationship with quality of life (QOL) is less clear. The purpose of this study was to assess the relationship between malnutrition and QOL. A prospective observational study was conducted in 36 adult patients undergoing allogeneic hematopoietic stem cell transplantation. Adapted criteria of the Global Leadership Initiative on malnutrition have been used for the diagnosis of malnutrition in clinical settings. A cancer linear analog scale was used to assess QOL. Overall QOL at 14 days after allogeneic hematopoietic stem cell transplantation was 37.1 (95% CI 2.9–45.39) in patients without severe malnutrition, versus 16.0 (95% CI − 6.6 to 38.6) in patients with severe malnutrition (p = 0.05). At discharge, it was 48.0 (95% CI 38.4–57.6) versus 34.0 (95% CI 4.1–63.9) (p = 0.27). The results of our study suggest that patients with severe malnutrition at discharge tend to have worse QOL. A larger cohort of patients is required to confirm this hypothesis.

096 Proposing Ultrasonic Elastography as New Evaluation Method for Erectile Function
Authors: Fumitoshi S , Seiji M , Toshikazu O , Tokunori Y , Kazuna M , Yasuharu T , Shikyo S 
Published: May 2022

ABSTRACT

Introduction
For diagnosing vasculogenic erectile dysfunction (ED), the prostaglandin E1 intracavernous injection test (PGE1 test) is an established method. However, its evaluation is often influenced by the subjectivity of the evaluator.

Objective
We objectively evaluated the changes in the corpus cavernosum before and after injection using percutaneous ultrasonic elastography in patients undergoing the PGE1 test.

Methods
We measured and evaluated the shear wave velocity in the corpus cavernosum by ultrasonic elastography (Canon Medical Systems Co., Ltd. Aplio i800) before and after injection, by a single doctor, in 16 patients who underwent the PGE1 test at our hospital, between April 2020 and March 2021.

Results
The response score of PGE1 tests were "1" in 2 cases, "2" in 2 cases, "3" in 12 cases, while "0" and "4" were not observed. The average transmission velocity before injection was 2.21m/s, and the average transmission velocity at the time of maximum erection after injection was 1.57m/s. In 14 of 16 cases (87.5%), the transmission velocity decreased during erection. The rate of change in transmission velocity due to injection was minus 26.7% overall, and was significantly different between the poor erection group (response 1 and 2: minus 16.1%) and the good erection group (response 3: minus 30.2%).

Conclusions
To our knowledge, this is the first report of an attempt to evaluate erectile phenomenon by ultrasonic elastography. The rate of change in the shear wave transmission velocity due to PGE1 test in the penile corpus cavernosum was associated with the degree of erection. It was suggested that the rate of change in shear wave transmission velocity in the penile corpus cavernosum could be used as an objective index of erectile phenomenon. Ultrasonic elastography is a non-invasive test method; therefore, it will be useful for patients if this method becomes established for diagnosing ED, determining the therapeutic effect, and predicting the prognosis.

108 Are There Differences in Stretched Flaccid Penile Length Versus Erectile Penile Length in Men with Erectile Dysfunction?
Authors: Martinez J Flores , Salter CA , Benfante N , Schofield E , Mulhall JP 
Published: May 2022

ABSTRACT

Introduction
Penile length measurement is an important tool in various clinical scenarios in andrology. It has been suggested that stretched flaccid penile length (SFPL) is an excellent surrogate for erect penile length (EPL).

Objective
We aimed to evaluate if the SFPL accurately reflects EPL.

Methods
Men with (i) Erectile Dysfunction (ED) without penile curvature (ii) undergoing penile duplex doppler ultrasound (DDUS) (iii) with a rigid erection were analyzed. SFPL and EPL were measured dorsally from the pubic symphysis to the coronal sulcus. Significant discrepancy was defined as a difference ≥1cm between the two measurements. We collected demographic and comorbidity data.

Results
64 men were analyzed with a mean age of 59.4 ± 13.4 years. 37.5% of the patients reported 2 or more comorbidities, 11% had diabetes, 19% obstructive sleep apnea, 29% were current or former smokers, 54% had radical pelvic surgery, and 44% pelvic radiation. Mean SFPL was 10.8 ± 1.9 cm and mean EPL was 11.8 ± 1.8 cm, (p&lt;0.001). 83% had EPL&gt;SFPL. 47% of men had a significant discrepancy between the two measurements. No predictors of discrepancy were identified.

Conclusions
In our cohort of men with ED assessed during DDUS, there was a statistically significant difference between SFPL and EPL measurements. In almost half of the cases EPL was significantly longer than SFPL. SFPL is not a reasonable surrogate for erect penile length
