Published: September 2022

AbstractQuartz cathodoluminescence (CL) images are commonly combined with trace element concentrations to decipher complex histories of hydrothermal systems. However, the correlations between aluminum content and CL zoning of low-temperature hydrothermal quartz and their genesis remain controversial. In this contribution, a multiparametric study was carried out on CL-aluminum zoning of low-temperature hydrothermal quartz (&lt;350 °C) from the Shihu and Rushan quartz-vein type Au deposits in the North China Craton. The results show that aluminum concentration correlates negatively with CL intensity in quartz from the Shihu Au deposit. CL-dark quartz zoning has significant Al concentrations as well as detectable Al-H bonds. However, in the Rushan Au deposit, the correlation is positive, and aluminum is enriched in the CL-bright quartz zoning. The Al content is positively correlated with K content with r2 = 0.769. Combined with the electron backscatter diffraction (EBSD), X-ray single crystal diffraction (XRD), and transmission electron microscope (TEM) data, we infer that the genesis of CL zoning in the low-temperature hydrothermal quartz is closely related to Al3+-H+ and Al3+-K+ concentrations. The Al3+-K+ may act as the CL-activator, while the Al3+-H+ may act as the CL-dampener. Where Al3+-Si4+ substitution is charge balanced by hydrogen, the intensity of CL response decreases; where Al3+-Si4+ substitution is charge balanced by potassium, the intensity of CL response increases. The correlations between CL intensity and aluminum concentration in the low-temperature hydrothermal quartz reflect pH fluctuations of hydrothermal system.

Published: September 2022

Abstract
Cold and dilute wastewater is a major challenge for N-removal at wastewater treatment plants. The moving-bed biofilm reactor process in combination with chemical coagulation/precipitation has proven suitable for nutrient removal under these conditions. Several full-scale plants based on combined pre- and post-denitrification for nitrogen removal and chemical coagulation/precipitation for phosphorous removal have been in operation for more than 20 years. These plants are still performing well, even at above design loads and at low temperatures (&lt;10°C). The success of this process configuration can largely be attributed to its flexibility of operation and control. In this paper the key instrumentation, control and automation elements are discussed and recommendations regarding process choice, reactor configuration and design are given.
A short-term water demand forecasting model using multivariate long short-term memory with meteorological data

Published: September 2022

Abstract
Sustainable management of water resources is a key challenge nowadays and in the future. Water distribution systems have to ensure fresh water for all users in an increasing demand scenario related to the long-term effects due to climate change. In this context, a reliable short-term water demand forecasting model is crucial for the optimal management of water resources. This study proposes a novel deep learning model based on long short-term memory (LSTM) neural networks to forecast hourly water demand. Due to the limitations of using multiple input sequences with different time lengths using LSTM, the proposed deep learning model is developed with two modules that process different temporal sequences of data: a first module aimed at dealing with short-term meteorological information and a second module aimed at representing the longer-term information of the water demand. The proposed dual-module structure allows a multivariate selection of the inputs with sequences of a different time length. The performance of the proposed deep learning model is compared to a conventional multi-layer perceptron (MLP) and a seasonal integrated moving average (SARIMA) model in a real case study. The results highlight the potential of the proposed multivariate approach in short-term water demand prediction, outperforming the more conventional approaches.
Hydrogeochemical and isotopic investigation of the multilayer aquifer system: a case study of the Quaternary and the Campanian aquifers of the Mateur plain, Northern Tunisia

Published: September 2022

Abstract
The Mateur multi-aquifer system, consisting of a Quaternary alluvial aquifer and a Campanian limestone aquifer, is one of the most significant aquifer systems in northern Tunisia, providing domestic and agricultural water supply for the entire Mateur region. The present study aims to unveil the various factors and mechanisms controlling the groundwater chemistry of such a system. Indeed, integrated hydrogeochemical and isotopic approaches are used herein to identify the alluvial and limestone aquifer waters mixing and evolution in the Mateur region. Results show that despite the difference in aquifer lithology, there is little difference in the major ion geochemistry and stable isotope ratios of groundwater within the Mateur plain. Waters from the Quaternary alluvial aquifer are classified into two predominant facies: mixed facies (Ca–Na–SO4–Cl and Ca–Na–HCO3–Cl) and Na–Cl facies. Similarly, waters from the limestone aquifer have also mixed facies (Ca–Na–SO4–Cl) and sodium chloride facies (NaCl). Groundwater δ18O and δ2H values show more homogeneous values along the groundwater flow direction, indicating inter-aquifer mixing processes. Tritium contents of the Campanian aquifer are lower than those of the Quaternary aquifer, indicating a relatively older age or mixture with recent waters. This validates a concept of the hydraulic continuity between the Quaternary aquifer and the Campanian aquifer which is consistent with the geochemical analytical results.
Monitoring the Nutrient Composition of Food Prepared Out-of-Home in the United Kingdom: Database Development and Case Study
Authors: Huang Yuru , Burgoine Thomas , Essman Michael , Theis Dolly R Z , Bishop Tom R P , Adams Jean 
Published: September 2022

Background
Hand transcribing nutrient composition data from websites requires extensive human resources and is prone to error. As a result, there are limited nutrient composition data on food prepared out of the home in the United Kingdom. Such data are crucial for understanding and monitoring the out-of-home food environment, which aids policy making. Automated data collection from publicly available sources offers a potential low-resource solution to address this gap.

Objective
In this paper, we describe the first UK longitudinal nutritional database of food prepared out of the home, MenuTracker. As large chains will be required to display calorie information on their UK menus from April 2022, we also aimed to identify which chains reported their nutritional information online in November 2021. In a case study to demonstrate the utility of MenuTracker, we estimated the proportions of menu items exceeding recommended energy and nutrient intake (eg, >600 kcal per meal).

Methods
We have collated nutrient composition data of menu items sold by large chain restaurants quarterly since March 2021. Large chains were defined as those with 250 employees or more (those covered by the new calorie labeling policy) or belonging to the top 100 restaurants based on sales volume. We developed scripts in Python to automate the data collection process from business websites. Various techniques were used to harvest web data and extract data from nutritional tables in PDF format.

Results
Automated Python programs reduced approximately 85% of manual work, totaling 500 hours saved for each wave of data collection. As of January 2022, MenuTracker has 76,405 records from 88 large out-of-home food chains at 4 different time points (ie, March, June, September, and December) in 2021. In constructing the database, we found that one-quarter (24.5%, 256/1043) of large chains, which are likely to be subject to the United Kingdom’s calorie menu labeling regulations, provided their nutritional information online in November 2021. Across these chains, 24.7% (16,391/66,295) of menu items exceeded the UK government’s recommendation of a maximum of 600 kcal for a single meal. Comparable figures were 46.4% (29,411/63,416) for saturated fat, 34.7% (21,964/63,388) for total fat, 17.6% (11,260/64,051) for carbohydrates, 17.8% (11,434/64,059) for sugar, and 35.2% (22,588/64,086) for salt. Furthermore, 0.7% to 7.1% of the menu items exceeded the maximum daily recommended intake for these nutrients.

Conclusions
MenuTracker is a valuable resource that harnesses the power of data science techniques to use publicly available data online. Researchers, policy makers, and consumers can use MenuTracker to understand and assess foods available from out-of-home food outlets. The methods used in development are available online and can be used to establish similar databases elsewhere.
The Effect of Telecommuting on Information Acquisition: Evidence from the U.S. Patent Office
Authors: Baek In Gyun 
Published: September 2022

ABSTRACT
I examine whether telecommuting, a work arrangement in which employees do not travel to a workplace, affects the acquisition of new information in an environment where thorough search and acquisition of information are essential. On the one hand, telecommuting may impede information acquisition due to reduced communication with colleagues. On the other hand, telecommuting may facilitate information acquisition due to relaxed time pressure (via not having to commute) and increased attentional resources (via quieter and uninterrupted working environments). I find employees' acquisition of new information increases following telecommuting. Further, I find that this effect is greater for employees under greater time pressure and employees experiencing greater distractions at the workplace before telecommuting and find that telecommuting causes adverse consequences for employees least responsive to organizations' incentive systems. Finally, I find that work quality improves following telecommuting. My results suggest telecommuting benefits employees performing knowledge-intensive tasks by facilitating employees' information acquisition.
Do Digital Technology Firms Earn Excess Profits? Alternative Perspectives
Authors: Rajgopal Shivaram , Srivastava Anup , Zhao Rong 
Published: September 2022

ABSTRACT
Despite regulators’ allegations that digital technology giants misuse their market power to earn abnormal profits, there is a dearth of systematic work on (1) whether digital-tech firms in general, and tech giants in particular, earn excess profits or (2) whether their abnormal profitability, if any, is due to market power. We use two alternative measures of economic profitability in addition to accounting rate of return (ARR): internal rate of return (IRR), which equates current investments to their long-term payback, and return on invested capital (ROIC), whose numerator (profits) and denominator (invested capital) are adjusted for capitalized intangibles. Inferences based on IRRs differ from those based on ARRs and ROICs. IRRs show that the digital-tech sector is now the best-performing sector, and its gap between profitability and cost of capital has increased over time. We are unable to separate the contribution of market power and innovation to digital tech’s high IRRs.

<p> </p>
<p>Objective: To evaluate the concordance between the ESC/EASD-2019 and the Steno Type 1 Risk Engine (Steno-Risk) cardiovascular risk scales in persons with type 1 diabetes (T1D) without cardiovascular disease (CVD), and to analyze their relationships with preclinical atherosclerosis. </p>
<p>Research design and methods: We consecutively selected patients with T1D, without CVD, with: ≥40 years, nephropathy, or ≥10 years of evolution with another risk factor. The presence of plaque at different carotid segments was determined by ultrasonography. Cardiovascular risk was estimated according to ESC/EASD-2019 risk groups (moderate/high/very-high) and the Steno-Risk (<10%, low; 10-20%, moderate; ≥20%, high), as T1D-specific scores. As an exploratory analysis, the non-T1D-specific ACC/AHA-2013 pooled cohort equation was also evaluated in individuals between 40-79 years. </p>
<p>Results: We included 501 patients (53% males, age 48.8 years, T1D duration 26.5 years, 41.3% harboring plaques). Concordance between T1D-specific scales was poor (kappa= 0.19). A stepped increase in the presence of plaques according to the Steno-Risk category was seen (18.4%, 38.2% and 64.1%, for low/moderate/high-risk; p for trend<0.001), with no differences according to ESC/EASD-2019 (p=0.130). Steno-Risk identified individuals with plaques, unlike ESC/EASD-2019 (AUC=0.691; p<0.001 vs. AUC=0.538; p=0.149; respectively). Finally, in polynomial regression models (adjusted for lipid parameters and cardioprotective treatment), irrespective of the ESC/EASD-2019 category, high-risk by Steno-Risk was directly associated with atherosclerosis (in moderate/high-risk ESC/EASD-2019: OR 2.91 [1.27-6.72] and 5.290 [2.746-10.189], for the presence of plaque and ≥2 plaques, respectively). Similar results were obtained with discordant higher Steno-Risk vs. ACC/AHA-2013 (p<0.001). </p>
<p>Conclusions: In T1D patient undergoing primary prevention, Steno-Risk seems to better recognize individuals with atherosclerosis in comparison to ESC/EASD-2019. Notwithstanding, carotid ultrasound could improve the categorization of cardiovascular risk. </p>
Impact of Cutting Units’ Design on Biomass Cutting Resistance
Authors: Zastempowski Marcin , Bochat Andrzej , Hujo Lubomir , Jablonicky Juraj , Janiec Maciej 
Published: September 2022

Abstract
The paper presents mathematical models describing the moments of resistance to cutting on the cutting drum shafts in the biomass cutting process. The mathematical procedures described in the paper have been verified on a test stand developed and constructed by the authors, which reflects real conditions of the process of cutting plant material into pieces of specified lengths. Experimental verification proved that the developed mathematical models are adequate for drums of both cylindrical and conical constructions. The value of the average error did not exceed 13%. Following the mathematical elaboration and verification studies, the authors carried out calculations for machines currently available on the market that are equipped with drum cutting units. The calculations were carried out for the most commonly cut material, i.e. for maize, straw and green plant materials. The obtained results confirm the complexity of the problem arising from a wide range of numerical values of cutting resistance, which is contained in the range of 400–1,800 nm. The compiled database can be practically applied in the selection of machines for specific field works, and the mathematical models developed and verified in the study can be applied at the stage of designing new designs of cutting drums used in forage harvesters.
Nonlinear Vibration Analysis of Beam and Plate with Closed Crack: A Review
Authors: Tewelde Samrawit A. , Krawczuk Marek 
Published: September 2022

Abstract
The effect of nonlinearity is high sensitivity in damage detection, especially for closed cracks and delamination. This review illustrates the results of several researchers dealing with nonlinear effects caused by the closure of cracks in the structure, i.e., beam and plate structures. Early detection of damage is an important aspect for the structure and, therefore, continuous progress is being made in developing new and effective methods that use nonlinear effects for early detection of damage and barely visible cracks, i.e., closed cracks and delamination, as well as for the determination of crack size and location. After analysing various methods, the merits, drawbacks and prospects of a number of nonlinear vibration methods for structural damage detection are discussed, and recommendations are made for future researchers.

Authors: Gogol Piotr , Trzcińska Monika 
Published: September 2022

Abstract
The aim of the experiment was to assess the correlation between sperm quality parameters and field fertility after AI with sex-sorted (X-bearing) bull semen. A total of 32 ejaculates from 26 Holstein-Friesian bulls were analyzed to assess sperm motility parameters (CASA), viability (SYBR-14/PI), apoptotic-like changes (YO-PRO-1/PI), chromatin structure (SCSA), and ATP content. In order to determine sperm fertilizing ability, 816 heifers and 727 cows were inseminated. Ultrasound diagnosis of pregnancy was performed on day 35 after insemination. For each ejaculate, the percentage of pregnant females was calculated separately. The results revealed that the pregnancy rate ranged from 20.0 to 85.7% for heifers and from 7.7 to 66.7% for cows. On the basis of the pregnancy rate (PR) obtained, the ejaculates were divided into 3 groups: high PR (about 25% of ejaculates), medium PR (about 50% of ejaculates) and low PR (about 25% of ejaculates). Significant differences were detected for amplitude of lateral head displacement (ALH) and beat cross frequency (BCF) between high- and low-fertility ejaculates in heifers. Pearson’s correlation analysis showed a significant relationship between the BCF and the pregnancy rate for heifers (r = 0.53, P<0.01) and there was a trend towards significance for ALH (r = −0.37, P = 0.07). There was no relationship between the sperm quality parameters and pregnancy rate of cows. In conclusion, the present study identified markers of sexed bull sperm function that were related to the fertility of inseminated heifers.

Abstract
The effects of a functional additive (Sanacore® GM; SAN) on immune and antioxidant indices, and the resistance of gilthead seabream (Sparus aurata) against Vibrio alginolyticus infection were investigated. For this, four diets containing 0% (the control), 0.1%, 0.2%, and 0.4% SAN were offered to triplicated groups of fish (20–23 g) for ten weeks. Subsequently, fish were injected intraperitoneally with V. alginolyticus and monitored for further ten days. Feeding the fish on SAN-supplemented diets showed positive effects on leukocyte counts and its differential percentages. Serum lysozyme activity and total immunoglobulin values, as well as blood phagocytic activity and indices, were linearly and quadratically higher in SAN-fed fish, especially at the 0.4% SAN diet. Similarly, linear and quadratic increases in catalase, superoxide dismutase, and total antioxidant capacity were observed in SAN-fed fish, particularly at the 0.4% SAN diet. Conversely, malondialdehyde values decreased in SAN-fed fish compared with the control group, which showed its highest value. The highest expression of the IL-1β gene coupled with the lowest TNF-α and HSP70 genes expressions was found in the fish fed with the 0.4% SAN. On the other hand, fish fed on the control diet showed the lowest IL-1β gene coupled with the highest TNF-α and HSP70 genes expressions. After bacterial infection, most of the control fish died with a relative percent of survival of 5.0%; meanwhile feeding gilthead seabream on SAN-enriched diets significantly enhanced their protection against V. alginolyticus infection fed on the 0.4% SAN diet showed 100% survival. The SAN administration to gilthead seabream especially at the 0.4% level led to significant promotions in antioxidative and immune responses and augmented the fish resistance to V. alginolyticus infection.

Rooftop solar PV installations have experienced rapid and unprecedented growth in Australia. However, one issue that contributes to inefficiencies in the electricity market is the ‘solar rebound effect’ which refers to the reduction in expected gains from eco-efficient technologies due to an increase in the use of the resource. However, little literature exists that incorporates consumers’ cognitions into studies of the solar rebound effect in Australia. This study aims to bridge a research gap by examining consumer perceptions of the solar rebound effect after installing rooftop solar, along with the psychological factors that might play a role in mitigating the solar rebound effects. A quantitative methodology was adopted, and a pilot survey was administered to residents (n=68) in a regional city. Frequency distributions and non-parametric tests were undertaken. The results indicate significant differences between those who report a solar rebound effect and those who do not, relating to factors such as thermal comfort, bill consciousness and an environmental self-identity. Implications for future research and practice are outlined in the paper.
