Authors: Anderson Natalie , Pringle Paul , Mead-Hunter Ryan , Mullins Benjamin , Larcombe Alexander , Allard Sebastien
Published: June 2023

Abstract. Introduction: Electronic cigarettes (e-cigarettes) lack regulatory status as therapeutic products in all jurisdictions worldwide. They are potentially unsafe consumer products, with significant evidence showing they pose a risk to human health. Therefore, developing rapid, economical test methods to assess the chemical composition of e-liquids in heated and unheated forms and the aerosols produced by e-cigarettes is crucial. Methods: Four different e-liquids were heated using two different methods: 1) “typical” vaping using an e-cigarette device, by cycling “on” for three seconds every minute for two hours (e-liquid obtained from the remainder in the tank and aerosol collected in an impinger) and, 2) “accelerated” heating, using an e-cigarette coil, submerged in e-liquid, and heating in short 20 second bursts “on” then 20 seconds “off” for two minutes only (liquid traps aerosol produced). All e-liquids were then analyzed to test for the presence and quantity of 13 chemicals by gas-chromatography mass-spectrometry and compared to an unheated sample. Results: E-liquids heated with the “accelerated” method showed a comparable trend to the “typical” heating method, of increase or decrease in chemical compound quantity, for greater than two-thirds of the detected compounds analyzed over all e-liquids. Six chemicals were detected as aerosol from the impinger fluid with the “typical” heating method, most at negligible levels. Conclusion: We propose this rapid method could form the basis of a standardized screening tool to test heated e-liquids (and e-cigarette aerosols) for harmful or banned substances to ensure only approved products reach the consumer, and the potential harms of e-cigarette use are reduced.

Authors: Meler Justyna , Litwicka Dagmara , Zabłocka Monika
Published: June 2023

Abstract. Measurements of light absorption coefficients by
particles suspended in seawater (ap(λ)), by phytoplankton (aph(λ)) and detritus (ad(λ)) were carried out in
the southern Baltic Sea for the original seawater samples and four size
fractions: pico-particles (0.2–2 µm), ultra-particles (2–5 µm), nano-particles (5–20 µm) and micro-particles (20–200 µm). Chlorophyll a (Chl a) and suspended particulate matter (SPM) concentrations
were determined. The proportions of particles from the size classes in the
ap(443), aph(443) and ad(443) were determined. Pico- and ultra-particles had the largest contribution to the total particle absorption – an average of 38 % and 31 %. Particles of 5–20 µm accounted for approximately 20 % of ap(443) and aph(443) and
29 % of ad(443). The contribution of particles > 20 µm averaged 5 %–10 %. In total SPM contribution of micro-particles averaged 17 %; nano-, ultra- and pico-particles averaged 29 %, 26 % and 27 %, respectively. In total Chl a, the proportions of pico- and ultra-particles averaged 35 % each, nano-particles 16 % and micro-particles 15 %. Temporal and spatial variability of particles contributions in size classes were observed. The average chlorophyll-specific and mass-specific light absorption
coefficients, i.e., light absorption coefficients normalized to Chl a or SPM, were determined for all size fractions. The chlorophyll-specific
coefficients ap(Chla)(λ),
ad(Chla)(λ) and
aph(Chla)(λ), ± standard deviations, do not allow clear separation of the individual fractions. For mass-specific coefficients, ap(SPM)(λ), ad(SPM)(λ) and
aph(SPM)(λ), it is possible to distinguish between large particles (20–200 µm) and small and medium particles (0.2–20 µm).
These results will allow monitoring of suspended matter in size classes in
optically complex waters of southern Baltic Sea.
Nonlinear processes in tsunami simulations for the Peruvian coast with focus on Lima/Callao

Published: June 2023

Abstract. This investigation addresses the tsunami flooding in Lima and Callao caused by the massive 1746 earthquake (Mw 9.0) along the Peruvian coast. Numerical modelling of the tsunami flooding processes in the nearshore includes strong nonlinear numerical terms. In a comparative analysis of the calculation of the tsunami wave effect, two numerical codes are used, Tsunami-HySEA and TsunAWI, which both solve the shallow water (SW) equations but with different spatial approximations. The comparison primarily evaluates the flow velocity fields in flooded areas. The relative importance of the various parts of the SW equations is determined, focusing on the nonlinear terms. Particular attention is paid to the contribution of momentum advection, bottom friction, and volume conservation. The influence of the nonlinearity on the degree and volume of flooding, flow velocity and small-scale fluctuations is determined. The sensitivity of the solution with respect to the value of the bottom friction parameter is investigated as well.
Investigating wind-driven Snow Redistribution Processes over an Alpine Glacier with high-resolution Terrestrial Laser Scans and Large-eddy Simulations

Published: June 2023

Abstract. Wind-driven snow redistribution affects the glacier mass balance by eroding or depositing mass from or to different parts of the glacier’s surface. High-resolution observations are used to test the ability of large eddy simulations as a tool for distributed mass balance modeling. We present a case study of observed and simulated snow redistribution over Hintereisferner glacier (Ötztal Alps, Austria) between 6 and 9 February 2021. Observations consist of three high-resolution Digital Elevation Models (∆x=1 m) derived from terrestrial laser scans taken shortly before, directly after, and 15 hours after snowfall. The scans are complemented by data sets from three onsite weather stations. After the snow fall event the snowpack decreased by 0.08 m on average over the glacier and typical snow redistribution patterns were observed. The decrease of the snow depth is to be attributed to both post-snowfall compaction and redistribution of snow. Simulations were performed with the WRF model at ∆x=48 m with a newly implemented snow drift module. The spatial patterns of the simulated snow redistribution agree well with the observed generalized patterns. Snow redistribution contributed -0.026 m to the surface elevation decrease over the glacier surface on 8 Feb, resulting in a mass loss of -3.9 kg m−2, which is in the same order of magnitude as the observations. With the single case study we cannot yet extrapolate to the impact of post-snowfall events on the seasonal glacier mass balance, but the study shows that the snow drift module in WRF is a powerful tool to improve knowledge on snow redistribution over glaciers and that the model setup can be applied to other mountain glaciers.

Published: June 2023

Abstract. In this article, a high-resolution acoustic emission sensor, accelerometer and broadband seismometer array data set is made available and described in detail from in-situ experiments performed at Äspö Hard Rock Laboratory in May and June 2015. The main goal of the hydraulic stimulation tests in a horizontal borehole at 410 m depth in naturally fractured granitic rock mass is to demonstrate the technical feasibility to generate multi-stage heat exchangers in a controlled way superior to former massive stimulations applied in enhanced geothermal projects. A set of six, sub-parallel hydraulic fractures is propagated from an injection borehole drilled parallel to minimum horizontal in-situ stress, and monitored by an extensive complementary sensor array implemented in three inclined monitoring boreholes and the near-by tunnel system. Three different fluid-injection protocols are tested: constant water injection, progressive cyclic injection, and cyclic injection with a hydraulic hammer operating at 5 Hz frequency to stimulate a crystalline rock volume of size 30 x 30 x 30 m at depth. We collected geological data from core and borehole logs, fracture inspection data from impression packer, acoustic emission hypocenter tracking and tilt data, as well as quantified the permeability enhancement process. The data and interpretation provided through this publication is an important step both, in upscaling laboratory tests, and downscaling field tests in granitic rock in the framework of enhanced geothermal system research.
The suitability of differentiable, physics-informed machine learning hydrologic models for ungauged regions and climate change impact assessment
Authors: Feng Dapeng , Beck Hylke , Lawson Kathryn , Shen Chaopeng
Published: June 2023

Abstract. As a genre of physics-informed machine learning, differentiable process-based hydrologic models (abbreviated as δ or delta models) with regionalized deep-network-based parameterization pipelines were recently shown to provide daily streamflow prediction performance closely approaching that of state-of-the-art long short-term memory (LSTM) deep networks. Meanwhile, δ models provide a full suite of diagnostic physical variables and guaranteed mass conservation. Here, we ran experiments to test (1) their ability to extrapolate to regions far from streamflow gauges and (2) their ability to make credible predictions of long-term (decadal-scale) change trends. We evaluated the models based on daily hydrograph metrics (Nash–Sutcliffe model efficiency coefficient, etc.) and predicted decadal streamflow trends. For prediction in ungauged basins (PUB; randomly sampled ungauged basins representing spatial interpolation), δ models either approached or surpassed the performance of LSTM in daily hydrograph metrics, depending on the meteorological forcing data used. They presented a comparable trend performance to LSTM for annual mean flow and high flow but worse trends for low flow. For prediction in ungauged regions (PUR; regional holdout test representing spatial extrapolation in a highly data-sparse scenario), δ models surpassed LSTM in daily hydrograph metrics, and their advantages in mean and high flow trends became prominent. In addition, an untrained variable, evapotranspiration, retained good seasonality even for extrapolated cases. The δ models' deep-network-based parameterization pipeline produced parameter fields that maintain remarkably stable spatial patterns even in highly data-scarce scenarios, which explains their robustness. Combined with their interpretability and ability to assimilate multi-source observations, the δ models are strong candidates for regional and global-scale hydrologic simulations and climate change impact assessment.
Realistic turbulent inflow conditions for estimating the performances of a floating wind turbine
Authors: Raibaudo Cedric , Gilloteaux Jean-Christophe , Perret Laurent
Published: June 2023

Abstract. A novel method for generating turbulent inflow boundary conditions for aeroelastic computations is proposed, based on interfacing hybrid hot-wire and particle image velocimetry measurements performed in a wind tunnel to a full-scale load simulation conducted with FAST. This approach is based on the use of the proper orthogonal decomposition (POD) to interpolate and extrapolate the experimental data onto the numerical grid. The temporal dynamics of the temporal POD coefficients is driven by the high-frequency hot-wire measurements used as inputs of lower-order model built using a multi time-delay linear stochastic estimation (LSE) approach. Being directly extracted from the data, the generated 3-component velocity fields later used as inlet conditions present correct one- and two-point spatial statistics and realistic temporal dynamics. Wind tunnel measurements are performed at a scale of 1:750, using a properly scaled porous disc as a wind turbine model. The POD analysis of the flow, with or without taking into account the presence of the surge motion of the model, shows that a few modes are able to capture the characteristics of the most energetic flow structures and the main features of the wind turbine wake such as its meandering and the influence of the surge motion. The interfacing method is first tested to estimate the performance of a wind turbine in an offshore boundary layer and then those of a wind turbine immersed in the wake of an upstream wind turbine subjected to a sinusoidal surge motion. Results are also compared to those obtained using the standard inflow generation method provided by TurbSim available in FAST.

An assessment of the possibilities of using the COSMO-Ru system for short-term forecasting of runoff of Russian rivers is carried out. An analysis of the forecast quality of the daily precipitation layer and average daily temperature of the surface air layer using this system is performed for 2081 weather stations. The quality characteristics of these forecasts are mapped. A forecast correction method was applied, which made it possible to increase the accuracy of forecasts on average by 20% for the precipitation layer and by 15% for air temperature. The quality of forecasting meteorological parameters averaged over the territory of 590 river basins turned out to be satisfactory for the precipitation layer and good for air temperature. The results give reason for a positive assessment of the possibilities of using the COSMO-Ru system for short-term forecasting of runoff of Russian rivers.

A method for calculating the daily streamflow was developed. The methodology uses the HBV-96 conceptual hydrological model. An output adjustment method was applied to the model calculations, which made it possible to significantly improve overall accuracy. The software package was created to develop, implement, and verify the methodology. The technique was implemented for 590 river catchments located throughout Russia in various natural conditions. An archive of all necessary hydrometeorological data for the period from 2010 to 2019 was formed. The results of verification based on an independent sample indicated a fairly high accuracy of calculations for the vast majority of river catchments. The results provide a basis for the development of an automated system for generating and issuing short-term streamflow forecasts for Russian rivers based on the proposed methodology.

Authors: Wei Yuting , Yuan Xue , Dong Yu ,   School of Management, University of Science and Technology of China, Hefei 230026, China
Published: June 2023

Since the supply chains of the world’s 2500 largest companies alone emit more than 20% of global greenhouse gases, how to achieve optimal cooperative supply chain emission reduction effects in supply chain optimal emission reduction efforts and effectively distribute revenue in cooperative supply chains is a difficult complex problem. In this paper, a green supply chain model of joint production is constructed based on the framework of the Stackelberg model and with carbon trading under three quota methods being taken into account. First, from the perspective of a supply chain leader, we obtain the optimal efforts to reduce emissions, the optimal price, and the yield of the products. Then, from the perspective of carbon market regulators, we obtain the environment that is most conducive to reducing emissions in the supply chain. Finally, we offer a profit distribution method based on the modified Shapley value, which maximizes fairness and stability. The data calculation example analysis further verifies the results of the theoretical analysis.

Published: June 2023

This study aims to establish a plan to revitalize the management of one-person hair shops by systematically researching relationship marketing as a way to strengthen the competitiveness of one-person hair shops and presenting it as basic data for marketing. For this study, a survey was conducted focusing on residents of the Seoul metropolitan area who have experience using or are using a one-person hair shop. The survey was conducted for about a month from January 15, 2023 to February 20, 2023, and 288 copies were used for statistical analysis. Frequency analysis, factor analysis, reliability analysis, regression analysis, and mediated regression analysis were performed using SPSS 25.0. As a result, it was confirmed that relationship marketing had a positive (+) effect on both customer emotional response and long-term orientation, and research on the mediating role of customer emotional response in the relationship between relationship marketing and long-term orientation showed that reliability and store image were completely mediated. Based on the results of this study, it was found that single-person hair shops need to not only make steady efforts to maintain consumers' long-term orientation by strengthening customer sentiment responses through differentiated relationship marketing, but also establish a system to manage customers systematically and efficiently. In-depth understanding of customers through customer emotional responses plays a major role in strengthening the competitiveness of One-person hair shops by maintaining positive relationships.

Published: June 2023

As appearance is regarded as one of the individual's abilities and the importance of appearance is emphasized day by day, many people make various efforts such as plastic surgery or weight management. In the case of married people, negligence in appearance management has a negative effect on appearance perception and decreases self-esteem, causing personal stress. In the age of super-aging, which goes beyond "well-being" to the concept of "well-aging," interest in skin aging and gray hair naturally continues, and it is important to understand how dyeing affects married customers. This study collected data from married people survey in Seoul to determine whether married people's dyeing color affects appearance recognition and dyeing satisfaction, confirming that married people's dyeing color can have a significant impact on appearance recognition and dyeing satisfaction. Hair beauty service workers help consumers consume effective beauty through marketing based on the results of these studies. In addition, it is possible to increase the satisfaction of married people's hair color choices and dyeing procedures through the use of coloring products that replace stimulating hair dyes and procedures suitable for individuals.

In this manuscript, the mean of the study and the auxiliary variable, as well as the rank of the auxiliary variable, were needed to develop a new, improved ratio-in-regression type estimator for population mean. Up to the first order of approximation, expressions for the bias and mean square error of the existing and proposed estimators are computed. The effectiveness and stability of our new, enhanced estimator are evaluated using simulation and two actual data sets. The suggested estimator's superior performance to all other considered estimators is shown both conceptually and numerically. The mean square error is the lowest, and PREs out-performs other known estimators by a factor of more than one hundred. Overall, we draw the conclusion that the suggested new improved estimator outperforms all its predecessors.

Particular attention is paid to the factors in the field of environmental safety and environmental management, which can dramatically affect the financial sustainability, development plans of SME companies in strategic planning and management, as well as investment decisions. The concepts of obvious and non-obvious risks for small and medium-sized businesses in the field of environmental safety, environmental management and sustainable development of the organization are given. Non-obvious risks of subsidiary responsibility for owners of SME companies associated with the lack of knowledge of environmental management were identified. The actions for SME companies focused on preventive forecasting and prevention of environmental risks in entrepreneurial activity were proposed.

Статья посвящена публикации материалов раннеалакульского могильника Нураталды-1, расположенного в 84 км к ЮВ от г. Караганды. Экспедицией Сарыаркинского археологического института при Карагандинском университете им. академика Е.А. Букетова было исследовано пять оград из каменных плит. Материалы ограды № 5, одна из могил которой содержала медный сосуд, были опубликованы ранее. Керамическая коллекция оград № 1–4 представлена 10-ю сосудами и фрагментами еще от 10 экз. Также были найдены металлические украшения, подвески из раковин и клыков животных, каменный амулет, костяные и бронзовый наконечники стрел. В двух сооружениях обнаружены парные жертвоприношения лошадей, характерные для раннего этапа алакульской культуры. Уникальной находкой является ритуальный клад металлических изделий, которые были изготовлены мастерами фёдоровской культуры. В научный оборот вводятся новые данные, показывающие, что взаимодействие между фёдоровским и алакульским населением проходило и в сфере обмена металлическими изделиями. По результатам радиоуглеродного анализа датировка памятника укладывается в два интервала – XIX–XVIII и XVIII–XVII вв. до н.э.

The donation of unharvested or unsold crops to rescue organizations has been promoted as a strat­egy to improve healthy food access for food inse­cure households while reducing production-level food loss and waste (FLW). In this study, we aimed to assess the motivations, barriers, and facili­tators for crop donation as a FLW reduction strat­egy among Maryland farmers. We interviewed 18 Maryland-based food producers (nine frequent crop donors and nine infrequent, by self-report) in 2016 – 2017, soliciting their perspectives on crop donation motivators, process feasibility, and inte­r­ventions aimed at increasing crop donation. The interviews were thematically coded. All respond­ents were aware of crop donation as an option, and most expressed interest in reducing FLW by divert­ing crop surpluses for human consumption. While financial barriers represented one aspect influenc­ing donation decisions, respondents also cited con­venience, process knowledge, and liability as key considerations. In contrast to frequent donors, many of whom considered donation a moral imperative, some infrequent donors questioned the expectation that they would donate crops without compensation. Both frequent and infrequent donors were aware of pro-donation tax incentives, and infrequent donors reported being unlikely to use them. This research demonstrates that crop donation motivations, barriers, and facilitators can be diverse. Given the existence of crop surpluses and their potential benefits as emergency food, our results suggest that multiple interventions and poli­cies may contribute to incentivizing and facilitating crop donation (or enabling the purchase of surplus crops) rather than one-size-fits-all approaches. Our findings also highlight a need to prioritize crop recovery methods that enhance growers’ financial stability.
Evidence and affects in Duchenne muscular dystrophy in children and Golden Retriever dogs

Introduction: Progressive muscular dystrophies differ in different ways due to their age of manifestation, the distribution of muscle weakness and the association of heart, central nervous system and peripheral nervous system. The most severe and common form of muscular dystrophies is Duchenne muscular dystrophy (DMD). Its involvement is 1/3500 male babies born alive and is attributed to 80% of cases of dystrophinopathies. The impairment of the dystrophin-glycoprotein complex in Becker and Duchenne dystrophies, in most congenital and girdle dystrophies, destruction of the sarcolemmal muscle fiber occurs, releasing muscle serum enzymes. Its characteristics are defined by clinical, histological and electromyographic criteria. The symptoms result from the weakness of the skeletal, cardiac and visceral muscles; progressively worsen; histological changes include muscle degeneration and regeneration, without evidence of abnormal storage of any metabolic; the disease is heritable, even without familial reports. Objectives: To compare the evidence and manifestations of DMD in humans in relation to Golden Retriever dogs with muscular dystrophy (GRMD), from breeders from Seattle-USA, named Canil GRMD — Brasil from the Department of Anatomy of the Faculty of Veterinary Medicine and Zootechnics of the Universidade de São Paulo. Conclusion: The model that most resembles humans are dogs, in terms of clinical and pathological aspects of muscular dystrophy. Golden Retriever dogs (GRMD) are genetically homologous to humans, and their histological lesions are identical to patients with DMD. GRMD dogs have been characterized as an ideal model for studies of the pathological and genetic mechanisms of DMD, as well as therapeutic trials.

Introduction: Aromatic L-amino acid decarboxylase (AADC) deficiency is caused by mutations in the DDC gene reducing AADC enzyme activity causing motor and neurodevelopmental impairments. Objectives: Evaluate clinical outcomes in children with AADC treated with Eladocagene exuparvovec, recombinant adeno-associated viral vector serotype 2 carrying the coding sequence for AADC enzyme. Methods: Therapy was infused bilaterally in the putamina of 30 patients aged 18–102 months receiving 1.8 × 1011 vg (n = 21) or 2.4 × 1011 vg (n = 9) followed for up to 120 months assessed using PDMS-2 key motor milestones including head control (partial or full), sitting (supported or independently), standing (with/away from support; up from cross-legged position), and walking (with/ without assistance; 10 feet; taped line). Motor milestones were measured every 3 months for 1 year following gene therapy, then every 6–12 months for ≤ 120 months. Data extracted on January 4, 2022. Results: At baseline, no patients had mastered head control or more advanced milestones. At year 1 of follow-up, patients were gaining the following skills (n): partial head control (26); full head control (15), sitting unassisted (7), supported standing (2). Progression of development was noted at years 5 and 10. By year 5 of follow-up, more advanced milestones were achieved (n): full head control (24), sitting unassisted (21) assisted walking (5), walking 10 feet (3), or walking upstairs (3). These abilities were maintained for as long as 10 years. Conclusion: The data indicate that eladocagene exuparvovec can provide a durable, positive impact on motor development in patients with AADC deficiency

Introduction: Tolosa Hunt syndrome (THS) is a rare condition, incidence of 1/1.000.000 case per year, characterized by unilateral painful ophthalmoparesis caused by idiopathic inflammation in the cavernous sinus. The oculomotor nerve is most commonly involved (80%), followed by abducens nerve (70%), ophthalmic branch of trigeminal nerve (30%), trochlear nerve (29%). Case presentation: Male, 77 years old, admitted with an acute moderate-intensity orbitofrontal headache on the left, envolving with palpebral ptosis of the left eye. Neurological examination: complete palpebral ptosis on the left and ophthalmoplegia of the entire ipsilateral extrinsic ocular musculature. A complete investigation was carried out: metabolic, rheumatological, serological tests without significant alterations and study of the cerebrospinal fluid with mild hyperproteinorachia, without pleocytosis. Magnetic resonance imaging (MRI) of the skull showed thickening of the cavernous sinus on the left, with contrast enhancement; Angio-MRI of the Skull and Neck without alterations. Therefore, THS was diagnosed and treatment with Methylprednisolone 1 g for five days, with complete improvement of headache and partial improvement of ophthalmoparesis. The patient was discharged with 60 mg of prednisone orally with instructions for gradual weaning off, return to the neurology outpatient clinic. Discussion: THS diagnosis is based on the International Classification of Headache Disorders: unilateral periorbital headache; granulomatous inflammation of the cavernous sinus, superior orbital fissure or orbit on cranial MRI; paralysis of one or more of the oculomotor nerves; the headache must precede the ophthalmoparesis by up to two weeks or appear concomitantly. The exclusion of secondary causes is essential. Treatment of choice is cortico steroids, improvement of headache in the first days, and of ophthalmoparesis in 2–8 weeks. Conclusion: Unilateral headache with ipsilateral ophthalmoparesis should raise the suspicion of THS.
