Published: March 2022

Pulmonary regurgitation following correction of tetralogy of Fallot (ToF) is a common postoperative complication associated with progressive right ventricular (RV) enlargement and dysfunction, and is an important determinant of late morbidity and mortality. Usually, pulmonary regurgitation is well tolerated for many years following surgery, but it can lead to progressive exercise intolerance, heart failure, tachyarrhythmias, late sudden death requiring often re-intervention. The appropriate timing of such intervention can be a challenging topic given the risk of prosthetic valve degeneration, the increased risk of reoperation and the decision depends on assessment of right ventricle size and function. Pulmonary hypertension (PH) is not an usual finding in ToF patient and it can be caused by pulmonary agenesis, hypoplasia and/or thrombosis, residual ventricular septal defect, or a large prior systemic-to-pulmonary shunt. Association of pulmonary arterial hypertension in a patient with ToF and pulmonary regurgitation who needs valve correction involves higher surgical risks and the management must be taken in a multidisciplinary team.

Published: March 2022

The effects of different contents of rare earth (RE) elements Ce and La on the corrosion behavior of weathering steel Q355NHq were investigated with alternate immersion tests and electrochemical measurements. The corrosion rates were lowest with the rusted steels containing 170 ppm RE elements. Aspex analysis showed that steels with the RE elements content of 170 ppm had the greatest percentage of inclusions with high content of RE elements. The immersion tests showed that modified inclusions with a high percentage of (RE)xOy exhibited a better corrosion resistance than CaS-Al2O3 inclusion. Compared with steels containing no more than 90 ppm RE, the rust layers of steels containing 170 ppm RE elements were compact and contained high amounts of α-FeOOH and low amounts of γ-FeOOH. Based on the results obtained, the influence of the different contents of RE elements in weathering steel corrosion is discussed.

Published: March 2022

Purpose

Computed tomography (CT)-guided percutaneous drainage has been used to address pelvic abscesses because it is safe and minimally invasive. However, CT-guided drainage has the limitation that the puncture route should be on the same axial slice. A technique for puncturing in the cranio-caudal direction under CT fluoroscopy is needed.

Case report

An 82-year-old man with an abscess due to rectal cancer was scheduled for CT-guided drainage to improve his general condition before radical surgery. Drainage was performed via a perineal approach to localize the drainage tract in the resection area to avoid dissemination of cancer cells. To perform a puncture in the cranio-caudal direction we controlled the needle like a joystick and advanced it under CT fluoroscopy while moving the CT gantry cranially to follow the needle tip throughout the puncture. Our unique technique yielded successful CT-guided puncture in the cranio-caudal direction.

Conclusions

Our unique technique overcomes the limitations of CT-guided cranio-caudal puncture and may allow the drainage of abscesses whose treatment was heretofore difficult.

Food system (FS) and food safety remain important issues in Vietnam. In which, producing and market accesing safe vegetables plays an important role. The production of safe vegetables has not been developed currently, , although the economic efficiency analysis shows that safe vegetable production uses less material input and commands higher prices, resulting in increased income for farmers. However, the production of safe vegetables requires more labor. The quality of safe vegetables is much better than that of conventional vegetables, but it needs to follow many criteria and standards. The network of safe vegetables in Thai Nguyen has not been developed (accounting for about 10% of total output), mainly safe vegetable consumption at supermarkets and some points of sale of safe vegetables, safe vegetable consumption is difficult. Point-of-sale are not convenient for buyers, and consumer satisfication remains low. More powerful and oriented policies and sets, especially in the planning of safe vegetable production and trading areas, communication on safe vegetable products, including traceability, and state support for products is required.

Analysis of the study is to assess the diagnostic significance of cytokines in the sperm plasma of men of reproductive age (20 - 45 years) of two groups: of patients with chronic bacterial prostatitis, not complicated by infertility and with loss of fertility. The study of sperm plasma - the WHO standard. Determination of the level of cytokines in seminal plasma - by enzyme immunoassay («Cytokine», Russia). Two methods of mathematical statistics were used: discriminant analysis and classification trees (decision trees).The similarity of interpretations of discriminant analysis and decision tree was noted, where the main role in both cases belongs to the cytokine IL-4. The level of sperm IL-4 in combination with therapeutic monitoring can be used for the medical management of patients with chronic prostatitis in order to prevent the development of infertility and to develop methods for screening diagnostics of fertility disorders in men.

Currently, in the diagnosis of diseases, a decisive place is given to laboratory methods, which should be informative, relatively simple to perform and rapid. The article describes the approbation of a method for rapid detection of Escherichia coli and bacteria of Escherichia coli group in the oral cavity. Research involved 44 volunteers, who were sampled from the oral cavity, followed by incubation in Koda’s medium. The study used oral (n=11) and gingival fluids (n=11); smears-prints from the oral mucosa (n=11); dental biofilm (n=11). After 24 hours, the change in color and transparency of the medium was assessed. The preservation of the initial green color and transparency by the medium meant the absence of E. coli and bacteria of Escherichia coli group in the sample. A change in the color of the medium to yellow, turbidity and / or the formation of bubbles indicated the presence of E. coli and bacteria of Escherichia coli group. In parallel, the material was inoculated onto Endo agar, followed by identification of strains to species. As a result of the study, a complete coincidence of the results of the classical bacteriological method and the method using Koda medium was shown. In the latter case, a significant advantage is the speed of obtaining the result (18-20 hours), in contrast to the classical method, the interpretation of the results of which is available only after 72 hours or more. All of this is in line with the state of the art in clinical microbiology and rapid diagnosis based on «point-of-care testing / doctor’s office» diagnostic principle. The presented method can be successfully applied in clinical practice for topical diagnosis of microorganisms E. coli and bacteria of Escherichia coli group in the oral cavity.

Published: March 2022

Abstract. Coastal regions are susceptible to multiple complex dynamic and chemical mechanisms and emission sources that lead to frequently observed large tropospheric ozone variations. These large ozone variations occur on a meso-scale which have proven to be arduous to simulate using chemical transport models (CTMs). We present a clustering analysis of multi-dimensional measurements from ozone Light Detection And Ranging (LiDAR) in conjunction with both an offline GEOS-Chem CTM simulation and the online GEOS-Chem simulation GEOS-CF, to investigate the vertical and temporal variability of coastal ozone during three recent air quality campaigns: 2017 Ozone Water-Land Environmental Transition Study (OWLETS) 1, 2018 OWLETS 2, and 2018 Long Island Sound Tropospheric Ozone Study (LISTOS). We developed and tested a clustering method that resulted in 5 vertical ozone profile curtain clusters. The established 5 clusters all varied significantly in ozone magnitude vertically and temporally which allowed us to characterize the coastal ozone behavior. The lidar clusters provided a simplified way to evaluate the two CTMs for their performance of diverse coastal ozone cases. The two models have fair-to-good relationships with the lidar observations (R = 0.66 to 0.69) in the low-level altitude range (0 to 2000 m), with unsystematic bias for GEOS-Chem and systemically high bias for GEOS-CF. In the mid-level altitude range (2000 to 4000 m), both models have difficulty simulating the vertical extent and variability of ozone concentrations in all 5 clusters, with a weak relationship with the lidar observations (R = 0.12 and 0.22, respectively). GEOS-Chem revealed a systematic high negative bias and GEOS-CF an overall low unsystematic bias range. Using ozone vertical distribution from lidar measurements, this work provides new insights on model’s proficiency in complex coastal regions.

Published: March 2022

Abstract. Spectral emissivity is a key property of the Earth's surface, of which only very few measurements exist so far in the far-infrared (FIR) spectral region, even though recent work has shown that the FIR is important for accurate modelling of the global climate. The European Space Agency's 9th Earth Explorer, FORUM (Far-infrared Outgoing Radiation Understanding and Monitoring) will provide the first global spectrally resolved measurements of the Earth's top-of-the-atmosphere (TOA) spectrum in the FIR. In clear-sky conditions with low water vapour content, these measurements will provide a unique opportunity to retrieve spectrally resolved FIR surface emissivity. In preparation for the FORUM mission with an expected launch in 2027, this study takes the first steps towards the development of an operational emissivity retrieval for FORUM by investigating the sensitivity of the emissivity product of a full spectrum optimal estimation retrieval method to different physical and operational parameters. The tool used for the sensitivity tests is the FORUM mission's end-to-end simulator. These tests show that the spectral emissivity of most surface types can be retrieved for dry scenes in the 350–600 cm−1 region, with an absolute uncertainty ranging from 0.005 to 0.01. In addition, the quality of the retrieval is quantified with respect to the precipitable water vapour content of the scene, and the uncertainty caused by the correlation of emissivity with surface temperature is investigated. Based on these investigations, a road map is recommended for the development of the operational emissivity product.
Bioclimatic change as a function of global warming from CMIP6 climate projections
Authors: Sparey Morgan , Cox Peter , Williamson Mark
Published: March 2022

Abstract. Climate change is predicted to lead to major changes in terrestrial ecosystems (Pörtner et al., 2022). However, significant differences in climate model projections for given scenarios of greenhouse gas emissions (Masson-Delmotte et al., 2021), continue to hinder detailed assessment. Here we show, using a traditional Köppen-Geiger bioclimate classification system (Köppen, 1884), that the latest CMIP6 Earth System Models actually agree very well on the fraction of the global land-surface that will undergo a significant change per degree of global warming. Data from ‘historical’ and ‘ssp585’ model runs are used to create bioclimate maps at various degrees of global warming, and to investigate the performance of the ensemble mean when classifying climate data into discrete categories. Using a streamlined Köppen-Geiger scheme with 13 classifications, global bioclimate classification maps at 2 K and 4 K of global warming above a 1901–1931 reference period are presented. These projections show large shifts in bioclimate distribution, with an almost exclusive change from colder, wetter bioclimates to hotter, dryer ones. Historical model run performance is assessed and examined by comparison with the bioclimatic classifications derived from the observed climate over the same time period. The fraction (f ) of the land experiencing a change in its bioclimatic class as a function of global warming (∆T ) is estimated by combining the results from the individual models. Despite the discrete nature of the bioclimatic classification scheme, we find only a weakly-saturating dependence of this fraction on global warming f = 1 − e −0.17∆T , which implies about 12 % of land experiencing a significant change in climate, per 1 K increase in global mean temperature between the global warming levels of 1 and 3 K. Therefore, we estimate that stabilising the climate at 1.5 K rather than 2 K of global warming, would save over 7 million square kilometres of land from a major bioclimatic change.
Effect of droughts on future weathering rates in Sweden

Published: March 2022

Abstract. In a future warmer climate, extremely dry, warm summers might become more common. In Scandinavia, the extreme summer of 2018 was such an event. Soil weathering is affected by temperature and precipitation, and climate change as well as droughts can therefore affect soil chemistry and plant nutrition. In this study, climate change effects on weathering were studied on seven forest sites across widely different climate zones in Sweden, using the dynamical model ForSAFE. Two climate scenarios were run, one climate change base scenario and one drought scenario. The model results show a large geographical variation of weathering rates for the sites. There is, however, no geographical gradient, despite the strong dependence of temperature on weathering, as also soil texture and mineralogy have strong effects on weathering. There is a pronounced seasonal dynamic, with much lower weathering rates during winters than during summers, and with more variable summer weathering rates depending on more variable soil moisture and temperature. According to the climate change base scenario, the weathering rates will increase by 5–17 % per degree of warming. The relative increase is largest in the two south-eastern sites, with low total weathering rates caused by relatively coarse soils and often dry summers. Changes in seasonal dynamics due to climate change differ between regions. At sites in southern Sweden, future weathering increase occurs throughout the year, though generally most in spring and summer. In the north the increase in weathering during winters is almost negligible, even though the temperature increase during winter is high, as the winter temperatures still will mostly be below zero. The drought scenario has the strongest effect in southern Sweden and here weathering can temporally become as low as winter weathering during drought summers. Soil texture also has an effect on how fast the weathering decrease during drought occurs, as well as how fast the soil rewets and resume normal weathering rates after the drought, where coarse soils respond quicker. Yearly weathering during the drought years in the most affected site is only 78 % of the weathering of the base scenario. In the north, the soils do not dry out as much despite the low precipitation, and in the northernmost site weathering is not much affected. The study shows that it is crucial to take seasonal climate variations and soil texture into account when assessing the effects of a changed climate on weathering rates and plant nutrient availability.
Continuous monitoring of a soil aquifer treatment system's physico-chemical conditions to optimize operational performance

Published: March 2022

Abstract. Soil aquifer treatment (SAT) is a tertiary process for wastewater treatment, where the wastewater infiltrates through a thick vadose zone for purification and storage in the underneath aquifer. SAT infiltration basins are typically flooded intermittently, while maintaining a fixed ratio between the wetting and the drying stages. However, infiltration basins exhibit different physical and chemical properties, limiting the generalization of SAT operation to attain optimal efficiency. Since frequent sampling of the soil pore water to verify the SAT's biodegradation efficiency can be arduous, continuous monitoring of the SAT vadose zone's physico-chemical conditions is required. In this study, redox potential (Eh) was continuously monitored, together with other variables, such as volumetric water content (θ), soil temperature, and gaseous oxygen (O2), at multiple depths of a SAT vadose zone throughout the year and while the system was constrained to different operational modes. Hydrological models were calibrated and validated to water content observations, and they illustrated the seasonal changes in water infiltration. Furthermore, it was shown that, under long wetting stages during winter, there was a reduction in the SAT's drainage capabilities. The Eh observations, under long wetting stages, demonstrated larger variability and very negative values as ambient temperature increased. Assembling the daily Eh observations illustrated that a wetting stage should cease after about 30 h, once suboxic conditions are established. A drying stage's optimal duration should be 36 h, according to the Eh and O2 observations during summer and winter. Ultimately, the study shows that the length of wetting and drying stages should be defined separately, rather than by adhering to the wetting / drying ratio.
Assembly and interconnection technology for high-temperature bulk acoustic wave resonators
Authors: Kohler Fabian , Farina Monika , Schulz Michal , Fritze Holger , Wilde Jürgen
Published: March 2022

Abstract. A sensor based on a piezoelectric single crystal enables operation even under harsh environmental conditions. In addition to the sensor element, the packaging technology is crucial for sensor performance. In this paper, a suitable assembly and interconnection technology concept of
Ca3TaGa3Si2O14 (CTGS) resonators for high-temperature applications is presented as a platform for future sensor assemblies. The concept described here has already been functionally tested as a temperature sensor (Schulz et al., 2021). The concept includes a sapphire base plate, a housing lid, and a spacer made from aluminium oxide (Al2O3). The substrate is metallised with platinum manufactured into thin film and thick film technology. The ceramic components are fused with glass solder. The connection of the resonator to the conductive tracks is realised by thermosonic bonding with 25 µm platinum wire. Initially, the stability of the metallisation must be investigated before subsequent electrical testing under high temperature. Diffusion processes play a major role in this temperature range, and the stability of the layer is a necessary condition for subsequent investigations. A suitable set of bonding parameters and the strength of the platinum bonds prior to and after thermal load is analysed. Shear tests are used to evaluate the quality of the ceramic materials fused with glass solder after thermal ageing. The dielectrical properties of sapphire and glass solder such as the isolation resistance, the relative permittivity, and the loss factor at high temperatures are evaluated using
interdigital structures. The loss factor is measured on both bare interdigital structures and the samples coated with glass solder to make an estimation about the conductive behaviour up to 1000 ∘C. A ceramic lid for the sensor housing is attached by a high-temperature stable glass solder. Since platinum conductors are fed through this glass solder connection, the electrical conductivity of the glass solder is characterised at high temperature. Furthermore, the hermeticity of the assemblies is verified by means of helium leakage tests. These investigations are the basis for the implementation of an assembly and interconnection technology that is suitable for reliable operation under extreme temperature conditions. The packaging technology also offers further possibilities for pressure or chemical sensors that can withstand high-temperature loads.

Abstract. Using observational data, satellite altimeters, and reanalysis model products, we have investigated eddy-induced seawater anomalies and heat/salt transport in the northeastern tropical Pacific Ocean. An eddy detection algorithm (EDA) was used to identify eddy formation at the Mexican Tehuantepec Gulf (TT) in July 2018 during an unusually strong summer wind event. The eddy separated from the coast with a mean translation velocity of 11 cm s-1 and a mean radius of 115 km and travelled 2050–2400 km westwards off the Central American coast, where it was followed at approx -114° W and 11° N for oceanographic observation between April and May 2019. The in-situ observations show that the major eddy impacts are restricted to the upper 300 m of the water column and are traceable down to 1500 m water depth. In the eddy core at 80 m water depth an extreme positive temperature anomaly of +8 °C, a negative salinity anomaly of -0.75 psu, a positive fluorescence anomaly of +0.8 mg m-3 and a positive dissolved oxygen concentration anomaly of 160 µmol kg-1 are observed. Considering the water volume trapped within the eddy, an average positive westward zonal heat transport anomaly of 85 × 1012 W and an average westward negative zonal salt transport of -2.2 × 106 kg s-1 are estimated. The heat transport is the equivalent of 1 % of the total annual zonal eddy-induced heat transport at this latitude in the Pacific Ocean. Understanding the dynamics of mesoscale eddies in this region of the Pacific Ocean is especially important in the light of potential deep-sea mining activities that are being targeted on this area.
