Self‐compassion at work: A self‐regulation perspective on its beneficial effects for work performance and wellbeing
Authors: Jennings Remy E. , Lanaj Klodiana , Kim You Jin (YJ) 
Published: February 2022

AbstractThe work environment is fraught with complex demands, hardships, and challenges, highlighting the need to approach work with self‐compassion each day. We propose that work self‐compassion—a mindset of kindness, gentleness, and care toward oneself as an employee—may generate the resources and motivation needed for self‐regulation at work. Drawing from integrated self‐control theory (ISCT) and theory on self‐compassion, we suggest that on days when employees hold a work self‐compassionate mindset, they will exhibit greater work performance and wellbeing via enhanced resource capacity and motivation. In an experimental experience sampling study, we found that a work self‐compassionate mindset reduced depletion and increased work self‐esteem and thereby heightened daily work engagement and daily resilience. Consequently, employees made greater goal progress at work and experienced higher meaning in life. In a supplemental study, we show that state self‐compassion at work is associated with unique variance in work outcomes beyond compassion received from coworkers. We discuss theoretical and practical implications for self‐compassion in organizational contexts.

AbstractBackgroundThe COVID‐19 pandemic has affected medical care worldwide. Thus, we aimed to assess the impact of the COVID‐19 pandemic on pediatric LT recipients.MethodsA cross‐sectional study based on a structured internet or telephone survey was conducted among pediatric LT recipients. Survey results were compared with results of a survey conducted among pediatric patients with IBD.ResultsSeventy‐six pediatric LT patients participated in the study. Of them, 58 (76.3%) reported fear of severe COVID‐19 infection due to LT or LT‐associated medications. Half of the patients reported needing emotional support. Most patients (51, 67.1%) reported strictly following official guidance, while more stringent protective measures were taken by 64 (84.2%) patients. None of the patients discontinued their medications due to COVID‐19. Compared to pediatric patients with IBD, a higher proportion of pediatric LT recipients reported fears of contracting severe COVID‐19 infection due to their illness or medications (45, 59.2% vs. 110, 45.1%).ConclusionAmong pediatric LT recipients a higher proportion reported fear of severe COVID‐19 infection, implemented additional protective measures and expressed a need for emotional support, compared to patients with IBD. Medical teams should provide adequate information and offer a support system for this vulnerable population.

AbstractColorectal cancer (CRC) is a leading cause of cancer‐related death worldwide. The spheroid colony formation assay is a useful method to identify cancer stem cells (CSCs). Using the DLD‐1 and WiDr CRC cell lines, we performed microarray analyses of spheroid body‐forming and parental cells and demonstrated that aldolase, fructose‐bisphosphate C (ALDOC) was overexpressed in the spheroid body‐forming cells of both lines. Cells transfected with small interfering RNA against ALDOC demonstrated lower proliferation, migration, and invasion compared with negative control cells. Both the number and size of spheres produced by the CRC cells were significantly reduced by ALDOC knockdown. Additionally, inhibition of ALDOC reduced lactate production. Immunohistochemistry was used to analyze ALDOC protein expression in tissues from 135 CRC patients and revealed that 66 (49%) cases were positive for ALDOC. The ALDOC‐positive cases were associated with higher T and M grades and, as determined by Kaplan–Meier analysis, a poorer prognosis. Univariate and multivariate analyses indicated that ALDOC expression was an independent prognostic factor for CRC patients. Furthermore, ALDOC expression was associated with CD44 expression. These results suggest that ALDOC contributes to CRC progression and plays an important role in CSCs derived from CRC.

Published: February 2022

AbstractBackgroundAlzheimer's disease (AD) is a common cognitive disease that can progress at an accelerating rate. Even with early diagnosis, the families might not recognize AD progressing unless behavioural and psychological symptoms of dementia (BPSD) develop. In many cases, discrepancies could exist between family‐assessed AD stage and diagnosed AD stage. This study explored such discrepancies and potential clinical implications.MethodsParticipants were 161 new outpatients with AD or mild cognitive impairment at four memory clinics whose AD stage was diagnosed using the Revised Hasegawa Dementia Scale (HDS‐R) and Mini‐Mental State Examination (MMSE). We classified patients into four groups according to AD severity. Family members completed the Functional Assessment Staging (FAST) scale during an interview. We then assigned patients to three groups according to discrepancies between family‐assessed and diagnosed AD stage.Families also completed the Neuropsychiatric Inventory Questionnaire (NPI‐Q), which assesses 12 neuropsychiatric domains, in order to examine the presence of BPSD in relation to AD stage.ResultsMost families (74%–80%) assessed patients as having milder AD than the diagnosed stage. NPI‐Q scores and duration of education significantly affected discrepancies with HDS‐R and MMSE scores. The NPI‐Q domains of anxiety, apathy/indifference, aberrant motor behaviours, and appetite/eating disturbance significantly affected family‐assessed FAST. Families of patients with more years of education assessed the AD stage as more advanced than the diagnosed stage. Surprisingly, living together did not significantly affect the discrepancy.ConclusionsMost families assessed AD as milder than the clinically diagnosed AD stage. In addition, high NPI‐Q scores and more years of school education significantly affected the discrepancy. Family‐assessed FAST was significantly affected by the NPI‐Q domains of anxiety, apathy/indifference, aberrant motor behaviours, and appetite/eating disturbance. These results suggest that obvious BPSD are significant factors for Japanese families to recognize AD progress.

AbstractThis study was aimed to investigate the combined effect of zinc sulphate and folic acid (ZnF) dietary supplementation on testicular haemodynamics (TH), testicular volume (TV), plasma testosterone levels (T) and semen quality of rams under heat stress conditions. Fifteen Ossimi rams were allocated to three groups: (1) G0 (n = 5) received only basic diet; (2) G1 (n = 5) received basic diet +ZnF (Zn, 0.4 mg/kg bw; F, 0.02 mg/kg bw) and (3) G2 (n = 5) received basic diet +ZnF (Zn, 0.8 mg/kg bw; F, 0.04 mg/kg bw) daily for 60 days. TH was evaluated using colour (testicular coloration, TC) and spectral modes [resistive index (RI) and pulsatility index (PI)] Doppler of the supra‐testicular arteries (proximal and distal parts, STA). Semen traits including progressive motility (PM), alive sperm % (AS), sperm viability (SV), sperm abnormalities (SA) and acrosome integrity (AI) were also assessed. The examinations were carried out one month before (D‐30), the beginning of ZnF inclusion in the diet (D 0) and continued for the successive two months (D 30 and D 60). TH was significantly (p < .05) improved at D 30 and D 60, evidenced by lowering both RI and PI and increasing of TC in G1 compared to G0 and G2. In addition, both TV and serum T levels were elevated (p < .05) at D 30 and D 60 in G1 compared to other groups. Semen quality parameters (PM, AS, SV and AI) were significantly (p < .05) augmented in the same trend as TH, TV and T in G1 versus G0 and G2. A marked decrease (p < .05) in SA % was noticed at Days 30 and 60 after ZnF inclusion in G1 compared to G0 and G2. In conclusion, supplementation of the summer diet with ZnF improved the whole reproductive functions such as testicular haemodynamics and semen quality of rams housed in heat stress conditions.
Identification of a Quaternary rock avalanche deposit (Central Apennines, Italy): Significance for recognition of fossil catastrophic mass‐wasting

Published: February 2022

AbstractWhereas deposits of extremely‐rapid, ‘catastrophic’ mass wastings >105 m3 in volume (for example, the Marocche di Dro rock avalanche in the Southern Alps and the Flims rockslide in the Western Alps) are easily recognized by their sheer mass and blocky surface, the identification of fossil catastrophic mass wastings partly removed by erosion must be based on deposit characteristics. Herein, a ‘fossil’ (pre‐last glacial) rock avalanche, previously interpreted as either a till or debris flow, is described. The deposit, informally called ‘Rubble Breccia’, is located in the intramontane Campo Imperatore halfgraben that is bounded by a master fault with up to ca 900 m topographic throw. Based on documentation from field to thin section, and by comparative analysis with post‐glacial rock avalanches, tills and debris flows, the Rubble Breccia is reinterpreted as a rock avalanche. The Rubble Breccia consists of an extremely‐poorly sorted, disordered mixture of angular clasts from sand to block size. Many clasts show fitted subclast boundaries in crackle, jigsaw and mosaic fabrics, as diagnostic of catastrophic mass wasting deposits. Intercalated layers of angular to well‐rounded clasts of coarse sand to fine pebble size, and deformed into open to recumbent folds, may represent shear belts folded during terminal avalanche propagation. The clast spectrum of the Rubble Breccia – mainly shallow‐water bioclastic limestones, Saccocoma wackestones and other deep‐water limestones and dolostones – is derived from the front range along the northern margin of the basin. Calcite cement found within the Rubble Breccia was dated with the U/Th disequilibrium method to 124.25 ± 2.76 ka bp, providing an ante‐quam age constraint to the rock avalanche event. Because catastrophic mass wasting is a common erosional process, fossil deposits thereof should be more widespread than have been identified to date, although this may be a consequence of misidentification. The criteria outlined here provide a template to identify fossil catastrophic mass wasting deposits of any age.

AbstractObjectiveThis study investigated the effects of temperature on the development of the immature stages ofAnopheles gambiae (s.l.)mosquitoes.MethodsMosquito eggs were obtained from laboratory established colonies and reared under eight temperature regimes (25, 28, 30, 32, 34, 36, 38 and 40°C), and 80 ± 10% relative humidity. Larvae were checked daily for development to the next stage and for mortality. Pupation success, number of adults produced and sex ratio of the newly emerged adults were recorded. Larval survival was monitored every 24 h, and data were analysed using Kaplan–Meier survival analysis. Analysis of variance was used where data followed normal distribution, and a Kruskal–Wallis test where data were not normally distributed. Larval and pupal measurements were log‐transformed and analysed using ordinary least square regression with robust standard errors.ResultsIncreasing the temperature from 25 to 36°C decreased the development time by 10.57 days. Larval survival (X2(6) = 5353.12,p< 0.001) and the number of adults produced (X2(5) = 28.16,p< 0.001) decreased with increasing temperature. Increasing temperatures also resulted in significantly smaller larvae and pupae (p< 0.001). At higher temperatures, disproportionately more male than female mosquitoes were produced.ConclusionsIncreased temperature affected different developmental stages in the life cycle ofAn.gambiae (s.l.)mosquitoes, from larval to adult emergence. This study contributes to the knowledge on the relationship between temperature andAnophelesmosquitoes and provides useful information for modelling vector population dynamics in the light of climate change.
Overview of Nuclear Piping Seismic Verification
Authors: Abe Hiroshi , Chokshi Nilesh 
Published: February 2022

Abstract
Nuclear power has gone through several transitional phases worldwide with early development, design, and construction in 1960s,1970s, and 1980s, particularly in Japan and US. There were some major research programs conducted during those years to develop methodology and prove the technology. Much of this knowledge is still very relevant and applicable and would be useful to young engineers and new professional coming to the nuclear industry. One of such programs is seismic verification of major structures, systems, and components (SSCs) by tests in Japan during the period of 1981 through 2004 at a large shaking table facility. Opportunities for conducting such large tests are not likely in the current environment of the industry and, therefore, one of the objectives of this paper is to summarize some earlier tests to raise awareness for the newcomers to the industry.
This paper discusses on Seismic verification tests of PWR and BWR Primary Loop, Main Steam and Feed Water line, Ultimate Strength of Piping and eroded piping , conducted in Japan. In particular, this paper focuses on: insights obtained from the test results; comparisons of test results with responses during actual earthquakes; collaboration of Japan and US in these tests; observations on robustness of Japanese seismic design; how the results relate to current issues; and use of these results from the future perspectives.
Reduced-Order Models for Effusion Modeling in Gas Turbine Combustors

Published: February 2022

Abstract
Effusion cooling represents the state-of-the-art for liner cooling technology in modern combustion chambers, combining a more uniform film protection of the wall and a significant heat sink effect by forced convection through a huge number of small holes. From a numerical point of view, a high-computational cost is required in a conjugate computational fluid dynamics (CFD) analysis of an entire combustor for a proper discretization of effusion holes in order to obtain accurate results in terms of liner temperature and effectiveness distributions. Consequently, simplified CFD approaches to model the various phenomena associated are required, especially during the design process. For this purpose, 2D boundary source models are attractive, replacing the effusion hole with an inlet (hot side) and an outlet (cold side) patches to consider the related coolant injection. However, proper velocity profiles at the inlet patch together with the correct mass flow rate are mandatory to accurately predict the interaction and the mixing between coolant air and hot gases as well as temperature and effectiveness distributions on the liners. In this sense, reduced-order (RO) model techniques from the machine learning framework can be used to derive a surrogate model (SM) for the prediction of these velocity profiles with a reduced computational cost, starting from a limited number of CFD simulations of a single effusion hole at different operating conditions. In this work, an application of these approaches will be presented to model the effusion system of a non-reactive single-sector linear combustor simulator equipped with a swirler and a multi-perforated plate, combining ansys fluent with a matlab code. The employed surrogate model has been constructed on a training set of CFD simulations of the single effusion hole with operating conditions sampled in the model parameter space and subsequently assessed on a different validation set.
Flow Non-Uniformity and Secondary Flow Characteristics Within a Serpentine Cooling Channel of a Realistic Gas Turbine Blade

Published: February 2022

Abstract
Unlike the ideal conditions considered in most previous studies, the actual cooling flow passage inside gas turbine blades is extremely complex. This complexity is due to the geometrical restrictions resulting from the external cooling holes and blade shape, which change the secondary flow and flow non-uniformity of the internal cooling flow. This study conducted an experimental and numerical analysis to characterize the secondary flow and flow non-uniformity in a realistic internal cooling serpentine passage. Magnetic resonance velocimetry was utilized to measure the average three-dimensional–three-components of the mean velocity. By integrating the flow field, parameters indicating the flow non-uniformity and secondary flow strength were obtained. Reynolds-averaged Navier–Stokes simulations were also conducted, and the Reynolds stress transport model showed relatively good performance when predicting the separation bubble in the U-bend. The secondary flow intensity exponentially decreases after the U-bend, but the rib turbulators maintain the secondary flow at a certain level. Additionally, the high-velocity regions in the inlet zone and beyond the separation bubble create significant flow non-uniformity and inherent shear. At the same time, the turbulence intensity becomes strong at the low-velocity region, which is key for heat transfer enhancement. Therefore, high flow non-uniformity has the potential to enhance heat transfer.
A Comparative Study of Thermal, Luminous, and Infrared Radiation Characteristics of Natural gas Flame in the Presence of Alkali, Alkali-Earth, and Transition Metallic Solution Additives

Published: February 2022

Abstract
Experiments were performed to find out the effect of alkali, alkali-earth, and transition metallic additives on thermal, luminous, IR, and total radiative properties of natural gas flame. A total of 25 mL of 0.5 M alkali salts of NaNO3 and KNO3, alkali-earth salts of Ca(NO3)2, Ba(NO3)2, and Sr(NO3)2 and transition nitrate salts of Cu(NO3)2 and Mn(NO3)2 (Merck company) were prepared, and flame tests were done on each solution by using a Bunsen burner with the equivalence ratio of 1.05, which is close to the condition of stoichiometric air–fuel mixing. The optical characteristics of flame were measured in visible and infrared radiation (IR) spectrums by a TES-1332A luminance meter, BOMEM FTIR, and IR flame photography technique. Also, the total radiation was gauged by a HFP01 sensor. The results indicated that, in general, due to the increased rate of nucleation of intermediate soot particles, the flame in the presence of alkali metal additives has higher total, luminous, and IR radiation than in the presence of other metal additives. Also, the metallic additives do not significantly change the flame temperature. The results also revealed that although all metallic additives enhance the luminous radiation of flame, which is due to chemiluminescence phenomenon or atomic emission, luminous radiation of metal additives is negligible in comparison with their radiation in IR wavelengths. Furthermore, the results show that the boiling temperature of metallic salt solutions has a greater impact on flame luminosity than their ionization energy does.
Pressure and Power Generation During Explosive Vaporization on a Thin-Film Microheater
Authors: Zhao Z. , Poulikakos D. , Glod S. 
Published: February 2022

Abstract
When a liquid is superheated above its boiling point to temperatures near or at the homogeneous nucleation limit, the energy released could create a so-called explosive vaporization, if a significant fraction of this energy is manifested in the form of vapor expansion. In this study, a thin-film microheater (100μm × 110μm) was placed on the underside of a water layer. The surface temperature of the heater was rapidly (6μs) raised electrically, well above the boiling point of water. As a result, rapid vaporization took place. Due to its rapid growth, the vapor volume performs mechanical work on its surrounding and emits acoustic pressure waves. By measuring the acoustic emission from an expanding volume, the dynamic growth of the vapor microlayer is reconstructed where a linear expansion velocity of 17 m/s was reached. Using the Rayleigh-Plesset equation, an absolute vapor pressure of 7 bar was calculated from the data of the acoustic pressure measurement. The amount of extractable mechanical energy produced from the explosive expansion of a vapor microlayer on a thin-film microheater surface, its rate of production, and the energy conversion efficiency was also quantified in this work.
Micro-Fluidic Design and Fluid-Structure Interaction Analysis of a Micro-Pump

Published: February 2022

Abstract
Conceptual design of a reversible micro-pump system is demonstrated by numerical simulations. Unsteady, incompressible Navier-Stokes equations in a moving boundary system are solved by ΝεκΤαr, a spectral element (high-order) algorithm employing an Arbitrary Lagrangian Eulerian (ALE) formulation on unstructured meshes. The performance of the micro-pump is evaluated as a function of the Reynolds number and the geometric parameters. The volumetric flowrate is shown to increase as a function of the Reynolds number. However, the efficiency of the micro-pump decreases with increased Reynolds number, due to the increased leakage effects.

Published: February 2022

Abstract
Recent experiments and simulations have demonstrated the feasibility of active boundary layer control in turbulent flows. Reduction of skin friction drag requires the development of sensors, actuators and control algorithms to favorably modify the boundary layer close to the wall. In this work, the actuator side of the problem is addressed, with the goal of developing a realistic actuation technology for boundary layer control experiments, and eventually, for use in real boundary layer control applications. Design issues in flow control applications are discussed. A process for fabricating arrays of zero mass flux vortex generators is described. Finally, the mechanical and fluid dynamic characteristics of the actuators are presented.
