Tracing Hazardous Materials in Registered Records: A Case Study of Demolished and Renovated Buildings in Gothenburg

Hazardous materials encountered during building renovation or demolition processes not only result in uncertainty in cost estimation and the lead time but also hampers material recyclability and reuse. Therefore, the paper discusses the possibility of predicting the extent of the hazardous materials, including asbestos, PCB, mercury, and CFC, through data mining techniques based on registered records. Pre-demolition audits contain observation data that can be used as a sample for statistical prediction through careful processing. By developing an innovative approach of merging data from environmental inventories with building registers, the positive ratio of remaining hazardous materials in the Gothenburg building stock can be estimated. The study highlights the challenges of creating a training dataset by completing information from the existing environmental inventory, providing new insight into digital protocol development for enhancing material circularity.

Performance of Two Different Flight Configurations for Drone-Borne Magnetic Data

The compensation of magnetic and electromagnetic interference generated by drones is one of the main problems related to drone-borne magnetometry. The simplest solution is to suspend the magnetometer at a certain distance from the drone. However, this choice may compromise the flight stability or introduce periodic data variations generated by the oscillations of the magnetometer. We studied this problem by conducting two drone-borne magnetic surveys using a prototype system based on a cesium-vapor magnetometer with a 1000 Hz sampling frequency. First, the magnetometer was fixed to the drone landing-sled (at 0.5 m from the rotors), and then it was suspended 3 m below the drone. These two configurations illustrate endmembers of the possible solutions, favoring the stability of the system during flight or the minimization of the mobile platform noise. Drone-generated noise was filtered according to a CWT analysis, and both the spectral characteristics and the modelled source parameters resulted analogously to that of a ground magnetic dataset in the same area, which were here taken as a control dataset. This study demonstrates that careful processing can return high quality drone-borne data using both flight configurations. The optimal flight solution can be chosen depending on the survey target and flight conditions.

Are They Careful Enough? Testing Consumers’ Perception of Alternative Processing Technologies on the Quality of Organic Food

Given the increasing public interest in how ingredients are processed and the growing demand for organic food products, it is critical to understand consumers’ expectations about the process-related quality of organic products. Consumers perceive organic food to be nutritious, healthy and either natural or less processed, as they are afraid of the loss of nutritional, organoleptic and sensory properties of the food products. However, alternative food processing technologies might generate healthy and safe food options with nutritional quality properties. Simplified communication schemes might help to overcome this barrier for the consumer. The main objective of this study is to propose a working definition of “careful processing” for organic products and test its consistency through an experiment, while being used to rate different processing methods by consumers. Results show that the proposed definition allows the consumer to consistently rate alternative processing technologies. Consumers tend to score alternative processing technologies such as pulsed electric fields and microwaves as less careful, supporting the idea that organic consumers want as little man-made interference in their food products as possible. Results show that a simple but effective definition of careful processing may help consumers to distinguish more organic food products from conventional ones, no matter which communication scheme is used.

Are They Careful Enough? Testing the Influence of Communication Schemes on Consumers’ Perception of Alternative Processing Methods for Organic Food

Given the increasing public interest in how ingredients are processed and the growing demand for organic food products, it is critical to understand consumers’ expectations about the process-related quality of organic products. In the minds of consumers, organic food is a concept related to either natural or less processed food, which leads them to prefer products obtained with careful processes. The main objective of this paper is to propose a working definition of "careful processing" for organic products and test its consistency while being used in scoring different processing methods by consumers. Results show that the proposed definition allows to consistently rate alternative processing methods. Consumers tend to score novel processing methods such as pulsed electric fields and microwave as less careful, supporting the idea that organic consumers want the least man-made interference with their food products. Results show that a simple but effective definition of careful processing may help consumers to distinguish further organic food products from conventional ones, no matter which communication scheme is used.

Rolʹ rukopysnoyi spadshchyny Lesi Ukrayinky u pidhotovtsi povnoho zibrannya yiyi tvoriv

Th e article discusses the preparation of the academic edition of the complete works by Lesya Ukrainka for publication carried out by the staff of the Volyn National University named aft er Lesya Ukrainka (Lutsk, Ukraine), with the involvement of leading literary critics of Ukraine. Th e implementation of this large-scale project (a collection of 14 volumes) became possible due to the fact that the university is the owner of the electronic archive of Lesya Ukrainka. Th e manuscript heritage of the writer has become available for detailed study by a wide range of researchers, in addition to remotely. Th e article states that careful processing of manuscripts revealed many problems in studying Lesya Ukrainka’s work, in particular, ideological interference in the process of publishing and interpreting manuscripts, especially draft manuscripts. Th e comparison of rough and clean autographs proved to be especially fruitful for commenting on texts, for an in-depth, and oft en completely new understanding of classical works. Th e organizers set a goal to fully refl ect the handwritten legacy of Lesya Ukrainka in comments and notes. Unfortunately, not every work of the writer received such an in-depth discourse, because many texts are presented in the collection of fi rst editions, as neither draft nor fi nal manuscripts were found. But even the available autographs allow us to interpret the writer’s manuscript heritage as a self-suffi cient object of science, to which it is necessary to apply not only the textual and genetic method but also many other methods of modern literary criticism.

Assessment of Extreme Diurnal Warming in Operational Geosynchronous Satellite Sea Surface Temperature Products

We evaluate the reliability and basic characteristics of observations of extreme DW events from current operational geostationary satellite sea surface temperature (SST) products through examination of three months of diurnal warming (DW) estimates derived by different methodologies from the Spinning Enhanced Visible and Infrared Imager on Meteosat-11, Advanced Himawari Imager on Himawari-8, and Advanced Baseline Imager on the Geostationary Operational Environmental Satellite (GOES)-16. This work primarily focuses on the following research questions: (1) Can these operational SST products accurately characterize extreme DW events? (2) What are the amplitudes and frequencies of these events? To answer these, we compute distributions of DW and DW exceedance and compare them amongst the different methods and geostationary sensors. Examination of the DW estimates demonstrates several challenges in accurately deriving distributions of the DW amplitude, particularly associated with estimating the “foundation” temperature and uncertainties in cloud screening. Overall, the results suggest that current geostationary sensors can reliably assess extreme DW, but the estimates are sensitive to the computational methods applied. We thus suggest careful processing/screening of the SST retrievals. We find a value of 3 K, corresponding to the 99th percentile, provides a potential practical threshold for extreme warming, but events of at least 6 K were reliably observed. Warming in excess of 6 K occurred somewhere an average of 47% of the time, and its probability at a given location was of O(10−6).

SCIENTIFIC CORRESPONDENCE OF I. A. ANTONOVA AND V. I. KUZISHCHIN AS A HISTORICAL SOURCE FOR THE STUDY OF THE NEAR CHORA OF CHERSONESOS AND THE ACTIVITIES OF THE HERACLEAN EXPEDITION IN THE 1970–90-IES

The article examines the history of the study of the near Chora of Tauric Chersonese on the Heraclean Peninsula in the 1970s–1990s on the basis of the scientific correspondence of the Director of the State museum-reserve «Tauric Chersonese» Inna Antonova and Professor of Moscow state University Vasily Kuzishchin. It is noted that the study of the correspondence of two scientists became possible due to the careful processing of I. A. Antonova documents in the museum’s archive. Particular attention was paid to the issue of the resumption of the Heraclean expedition activities, which was discussed in the letters of scientists to each other. It is concluded that only after studying, systematizing and analyzing all the materials preserved in the Chersonesе archive it will be possible to give a proper assessment of the contribution of I. A. Antonova in the research and public life of the museum, city, country, as well as the contribution of her correspondents, one of whom was V. I. Kuzishchin.

Simultaneous and Successive Emotion Experiences and Health and Risk Messaging

Emotions are an important part of how audiences connect with health and risk messages. Feelings such as fear, anger, joy, or empathy are not just byproducts of information processing, but they can interact with an individual’s perception and processing of the message. For example, emotions can attract attention to the message, they can motivate careful processing of the message, and they can foster changes in attitudes and behavior. Sometimes emotions can also have counterproductive effects, such as when message recipients feel pressured and react with anger, counterarguments, or defiance. Thus, emotion and cognition are closely intertwined in individuals’ responses to health messages. Recent research has begun to explore the flow and interaction of different types of emotions in health communication. In particular, positive feelings such as joy and hope have been found to counteract avoidant and defensive responses associated with negative emotions such as fear and anger. In this context, research on health communication has begun to explore complex emotions, such as a combination of fear and hope, which can highlight both the severity of the threat, and individuals’ self-efficacy in addressing it. Empathy, which is characterized by a combination of affection and sadness for the suffering of others, is another example of a complex emotion that can mitigate defensive responses, such as anger and reactance, and can encourage insight and prosocial responses.

Effect of drying methods for inner parameters of red beetroot (Beta vulgaris L.)

In compliance with consumer expectations, careful processing and preservation are increasingly used with fruits and vegetables. The aim is that during these treatments the valuable nutritional characteristics of the raw materials change as little as possible. Drying has been used for the preservation of raw materials for a long time, which can distinguish two different groups based upon pressure. These are the atmospheric and the more careful vacuum drying. During the research, Alto F1 beetroots were being dried in vacuum and under atmospheric pressure at different temperatures. Vacuum drying took place at 40, 50, and 60 °C, while atmospheric drying at 60, 70, and 80 °C. All drying processes lasted 150 minutes. During drying, changes of moisture content and water activity were monitored. After drying, colour measurement was realized and the inner parameters were investigated, such as polyphenol, betalain, and antioxidant capacity. These measured parameters were compared in the ease of atmospheric and vacuum drying.

Fuel Flexible and Reversible Operation of Yttrium-Doped Strontium Titanate Anode Supported SOFC

The performance of novel yttrium-doped SrTiO3 (Sr0.86Y0.08TiO3, SYT) anode materials for an anode supported SOFC have been evaluated in terms of fuel flexibility and reversible operation at intermediate temperature (800°C). The SYT anode supported PEN structures were fabricated using tape casting, dip coating and screen printing for the anode substrate, electrolyte and cathode, respectively. Overall performance of SYT-YSZ composite anode supported cells indicates that this anode material set is not likely to be an outstanding performer, mainly due to the significant anode polarization losses and relatively high ohmic losses. With careful processing of the anode during cell fabrication, major parts of the ohmic losses introduced by the SYT anode can be reduced. The results also indicate that Ni infiltration of the SYT anode can lead to smaller polarization losses, thus achieving better cell performance.
