Authors: Avanesova Jeļena , Lieldidža-Kolbina Jeļizaveta
Published: August 2022

During COVID-19 pandemic, interest in mHealth rose dramatically. An ample literature review was carried out to discover whether personality traits could be the basis for mHealth personalization for human-computer interaction improvement. Moreover, the study of three most popular mHealth applications was conducted to determine data collected by users. The results showed that personality traits affected communication and physical activity preferences, motivation, and application usage. mHealth personalization based on personality traits could suggest enjoyable physical activities and motivational communication. mHealth applications already process enough user information to enable seamless inference of personality traits.
Internet User Trackers and Where to Find Them
Authors: Teze Vitalijs , Nazaruka Erika
Published: August 2022

In the modern online world, users are often asked for a permission to track their actions as a permission to “allow cookies”. The gathered information could be very valuable for a potential advertiser. However, online tracking is not only a benefit for a user but also a threat to the user’s privacy. This information combined with a targeted advertisement on a mass scale has potential to alter behaviour of large groups. This study summarises previous academic work on online user tracking and anti-tracking measures. As a result, it describes the current mechanisms used to track a user, as well as some methods that can be applied to reduce tracking. The study concludes that government legislation and open dialog between Internet users and advertisers might be the only way to ensure online privacy.

Authors: Bran Petronela Elena , Nicuţă Daniela , Grosu Luminiţa , Patriciu Oana-Irina , Alexa Irina-Claudia
Published: August 2022

The grape pomace hydroalcoholic extracts obtained by two different extraction methods were tested for biostimulatory potential activity for Origanum vulgare L. cultures. The total polyphenols contents of extracts were evaluated by Folin-Ciocalteu method. Characteristics such as: pH, salinity, conductivity and total dissolved solids were determined. FTIR and UV spectra of extracts were also recorded. The effect of grape pomace extracts on growth and development of oregano plant were studied by carrying out in vitro propagation of oregano on Murashige and Skoog basal medium supplemented with different concentrations of grape pomace extracts. Biometric measurements, growth rate and biomass accumulation have been narrowly monitored for all samples and compared to the control sample. The results have shown that the morphogenetic response depends both on the proportion in which basal medium was supplemented and on the extraction method used. A stimulation of growth and development at a low concentration of grape pomace extracts has been noted. The best results were observed in the samples with 1 and 5 % of grape pomace extract obtained by classical extraction.

Authors: Fér Miroslav , Nikodem Antonín , Trejbalová Sára , Klement Aleš , Pavlů Lenka , Kodešová Radka
Published: August 2022

An application of different mulch materials may lead to changes in soil properties. Our previous study, focused on the impact of various mulches during the 4-year period, showed that the change in some properties can be very rapid (e.g., soil pH), but in other cases such as hydraulic properties, the changes can be gradual. To find out, whether the extension of the mulching period will further affect the studied soil properties, the experiment continued for another 2 years. Differences between values of organic carbon content (Cox), soil physical quality (S
inf), gravitational water (GW) and readily available water (RAW) of soils not covered by any mulch and under various mulches (bark chips; wood chips; wheat straw; Agrotex EKO+ decomposable matting; polypropylene fabric covered bark chips; crushed stone) were much larger than those observed in our previous study. On the other hand, the opposite trend was observed for the water stable aggregates (WSA) index or soil pH. Differences between additionally measured hydraulic conductivities at the pressure head of −2 cm and repellency index (RI) were mostly insignificant. Results indicated that organic mulches can either positively (e.g., increase WSA index and Cox, and decrease GW) or negatively (e.g., decrease S
inf and RAW, and increase RI) affect soil properties.

Authors: Botyanszká Lenka , Šurda Peter , Vitková Justína , Lichner Ľubomír , Igaz Dušan
Published: August 2022

Microplastics (particles of plastics <5 mm) affect the physical, biological and hydrological properties of agricultural soil, as well as crop growth. We investigated the effect of the addition of three microplastics (high-density polyethylene (HDPE), polyvinyl chloride (PVC), and polystyrene (PS)) at a concentration of 5% (w/w) to a silty loam soil on selected soil properties and growth of radish (Raphanus sativus L. var. sativus). Changes in the soil properties and radish growth in three microplastic treatments were compared with the control. Soil properties (bulk density, hydraulic conductivity, sorptivity, water repellency) were estimated for each treatment at the beginning and at the end of the radish growing period (GP). The bulk density was significantly lower in the HDPE and PVC treatments compared to the control within the measurement at the beginning of the GP and in all microplastic treatments compared to the control at the end of the GP. The values of hydraulic conductivity and water sorptivity did not show significant differences between any treatments within the measurement at the beginning of GP, but they were significantly higher in the HDPE treatment compared to the control at the end of the GP.

The growth of radish was characterized by the plant biomass and effective quantum yield of Photosystem II (Y (II)). We did not find a statistically significant difference in the total biomass of radish between any of the experimental treatments, maybe due to used concentration of microplastics. The mean value of Y (II) was significantly higher in all microplastic treatments compared to control only within the last measurement at the end of the GP. A statistically significant change of Y(II) in all microplastic treatments may indicate functional shift in soil properties; however, the measured values of the soil characteristics have not shown the significant changes (except for the bulk density values in all microplastic treatments and hydraulic conductivity together with sorptivity in HDPE treatment within the measurement at the end of GP).
Generational Differences in the Labour Market – Three Confounded Effects
Authors: Wilczyńska Kinga , Wieczorkowska Grażyna
Published: August 2022

Objective: Many research claim that Millennials value work ethic much lower and leisure time much higher than older generations. Most of them are based on cross-sectional analyses of data collected at one time. This design confounds the COHORT effect (born in the same time period and thus exposed to the same cultural forces during their formative socialization period) and biological AGE, and it makes it impossible to separate them. Our goal is to demonstrate how to empirically separate the confounded effects of APC (biological AGE – PERIOD of measurement – COHORT) in a simple way.

Methodology: Three generations (Baby Boomers, X-ers and Millennials) from the representative Polish samples of the World Value Survey, were cross-sectionally compared, and a cross-lagged comparison was made between BB in 2005 vs X in 2020, and between X in 2005 and Millennials in 2020.

Findings: It was shown that significant cross-sectional differences in attitudes toward work between the 3 generation (with the highest score for Baby Boom-ers and the lowest for Millennials) cannot be explained by age differences. Over the period of 15 years, the importance of leisure time has increased for all generations (PERIOD effect).

Value Added: The paper highlights significant methodological problem: the confounding effect of APC in most generational findings. It promotes the idea of using nationally representative samples from publicly available data like World Value Survey, instead of collecting convenience samples.

Recommendations: Greater methodological rigour in generational studies is recommended, as their results can create/support stereotypes that tend to generate individual expectations (e.g. every Millennial is computer literate or lazy), ignoring the fact that intra-generational variability is very high.

Authors: Ayoub Asad , Balawi Ayman
Published: August 2022

Objective: The purpose of this paper is to examine the impact of social media on customer experience and how companies can use social media to enhance the experience of customers.

Methodology: Literature synthesis method was followed to trace out and analyse the data. The EBSCO Discovery of Science and Google Scholar databases were used to find the articles. Over thirty articles were produced from the total (190) search query results after applying limiters, deleting duplicates, and enforcing non-business settings.

Findings: Social media has a considerable impact on customer experience due to its widespread and easy access by customers. It enabled companies to classify customers, get a lot of information about them, and get very fast feedback about their impressions related to their product or services. Social media may have a positive or negative impact on customer experience, so the role of management is important to manage these media in a way that will benefit the company and support it to achieve its objectives.

Value Added: This article provides a clear picture on exploring the impact of social media on customer experience. The results of the research can be used to guide companies on how to use social media to enhance the experience of customers.

Recommendations: Companies should smartly manage social media and employ qualified staff to improve the customer’s experience and avoid the side effects that this type of media may have on customer experience. In addition, customer experience should be a strategic goal because it helps the company meet its overall goals.
The geopolitics of territorial relativity. Poland seen by Rudolf Kjellén
Authors: Lundén Thomas
Published: August 2022

Rudolf Kjellén (1864–1922) discusses the birth, death, and possible rebirth of the state as a ‘living organism’. His concept of the nation, based on Renan, as a voluntary community is linked to the attainment of statehood. Poland is an example in this discussion, beginning in his book Stormakterna – The Great Powers – in 1905, with the nation under subjugation by three of these powers, continuing with his Staten som lifsform in 1916 where the possibility of rebirth is in sight, and finalized in 1920 in questioning the future of the world geopolitical order. His writings also include statements on the vulnerability of borders, the need for domestic autarky, and, on the problems of territorial autonomy, discussions of importance for the post-World War I geopolitical history of Poland; but these have mostly been neglected by post-World War II discourses. The aim of this article is to analyse how Poland's geopolitical situation is reflected in the viewpoints of Rudolf Kjellén against the background of the historical, spatial development of the Polish state and Polish ethnicity.
Automation of slice thickness measurements in computed tomography images of AAPM CT performance phantom using a non-rotational method
Authors: Ximenes Angelita D , Anam Choirul , Hidayanto Eko , Naufal Ariij , Rukmana Dito A , Dougherty Geoff
Published: August 2022

Purpose: The current study proposes a method for automatically measuring slice thickness using a non-rotational method on the middle stair object of the AAPM CT performance phantom image.

Method: The AAPM CT performance phantom was scanned by a GE Healthcare 128-slice CT scanner with nominal slice thicknesses of 0.625, 1.25, 2.5, 3.75, 5, 7.5 and 10 mm. The automated slice thickness was measured as the full width at half maximum (FWHM) of the profile of the middle stair object using a non-rotational method. The non-rotational method avoided rotating the image of the phantom. Instead, the lines to make the profiles were automatically rotated to confirm the stair’s location and rotation. The results of this non-rotational method were compared with those from a previous rotational method.

Results: The slice thicknesses from the non-rotational method were 1.55, 1.86, 3.27, 4.86, 6.58, 7.57, and 9.66 mm for nominal slice thicknesses of 0.625, 1.25, 2.4, 3.75, 5, 7.5, and 10 mm, respectively. By comparison, the slice thicknesses from the rotational method were 1.53, 1.87, 3.32, 4.98, 6.77, 7.75, and 9.80 mm, respectively. The results of the nonrotational method were slightly lower (i.e. 0.25%) than the results of the rotational method for each nominal slice thickness, except for the smallest slice thickness.

Conclusions: An alternative algorithm using a non-rotational method to measure the slice thickness of the middle stair object in the AAPM CT performance phantom was successfully implemented. The slice thicknesses from the nonrotational method results were slightly lower than the rotational method results for each nominal slice thickness, except at the smallest nominal slice thickness (0.625 mm).
Investigating the effect of layer thickness on the variability of porous asphalt tyre/road noise
Authors: Bull John , Wareing Rob , Chiles Stephen , Jackett Richard
Published: August 2022

Longitudinal variability in tyre/road noise is often associated with low-noise porous asphalt surfaces, with CPX testing results for individual 20-metre road segments commonly varying by up to 6 dB along new projects in New Zealand. In November 2018, following on from previous trials investigating the effects of air voids and stone size, three EPA7 trial sections were constructed to investigate the effects of layer thickness on tyre/road noise. The thickness effect was found to be approximately –2 dB LCPX:P1,80 per 10 mm increase in target layer thickness across the three trial sections. Core samples taken from a new road showed EPA7 layer thicknesses that differed from the target layer thickness by up to 15 mm. These findings suggest that variations in layer thickness may be a key contributor to longitudinal variations in tyre/road noise on roading projects using porous asphalt. A further investigation involving a detailed thickness survey is currently underway to better understand layer thickness variability and its effect on tyre/road noise.
Impact of the Internal Structure Density in the Process of Fabrication of Orthodontic Master Models by Fused Deposition Modeling
Authors: Milde Jan , Papagiannopoulos Dimitrios , Thurzo Andrej
Published: August 2022

The article focuses on the influence of infill (internal structure of components) in the dimensional accuracy of dental master models during the processes of their fabrication by Fused Deposition Modeling (FDM) technology, and their vacuuming process for production of clear orthodontic aligners. The components, in this case, were the upper jaws (maxillary teeth) of two individual patients (Tzina, Dimitris), which were obtained by intraoral 3D scanning. Patient Tzina at the time of intra-oral scanning was 27 years old and Dimitris was 23 years old. The method of 3D printing was the FDM, and the material used in this research was thermoplastic high impact polystyrene (HIPS). Three different percentages of infill density were set, 60%, 80%, and 100%. For each setting, there were five specimens (thirty 3D printed dental models in total, 15 for Tzina and 15 for Dimitris). After the 3D printing, the models were digitized and measured by GOM ATOS II Triple Scan MV 170 optical 3D scanner and compared with the values of the initial digital models. Then the dental master models underwent the process of Essix-aligners formation (single press) and were rescanned and measured again. The outcome of this research was to examine if the dental master models remain dimensionally accurate after these processes, and which infill provides the optimal and medically approved accuracy.

Aim: Assessed the correlation between prostate volume and intravesical prostatic protrusion with detrusor wall thickness through transabdominal sonographic examination of benign prostate enlargement (BPE). Methods: The study is a paired-group analytical observational cross-sectional study during April – July 2020. Measurements were made of prostate volume, intravesical prostatic protrusion, and detrusor wall thickness using transabdominal sonography. An analysis was carried out to determine the correlation with bivariate analysis and the calculation of the research power. Results: Thirty-four BPE patients with a mean age of 62.41 years were included in the study. The mean value of prostate volume obtained was 44.24 cc; 8.66 mm for intravesical prostatic protrusion; and detrusor wall thickness is 1.49 mm. The correlation value between prostate volume and detrusor wall thickness was 0.12 (p=0.46), while the intravesical prostatic protrusion and detrusor wall thickness were 0.37 (p=0.03). The research power for correlating prostate volume with detrusor wall thickness and intravesical prostatic protrusion with detrusor wall thickness was 10-20% and 50-60%, respectively. Conclusion: There is a very weak correlation between prostate volume and detrusor wall thickness and a weak correlation between the intravesical prostatic protrusion and detrusor wall thickness. Other variables may influence the thickness of the detrusor wall.

No atual cenário sociopolítico brasileiro, a discussão sobre o papel das avaliações externas e sua interferência na formação de políticas públicas educacionais tem sido cada vez mais presente. Este trabalho nasce do questionamento sobre como a avaliação do Programme for International Student Assessment (PISA) influencia a educação no Brasil e toma como perspectiva teórica a análise de discurso de linha francesa. A partir da pergunta de pesquisa, estabeleceu-se como objetivo geral refletir sobre a forma como a mídia representa e divulga os resultados das avaliações do PISA e como isso pode afetar a educação como um todo, no sentido de moldar as políticas públicas dos países que aplicam a prova, como o Brasil; como objetivos específicos, buscou-se levantar reportagens da Folha de São Paulo sobre a última avaliação do PISA, edição de 2018, e analisar discursivamente duas reportagens. O corpus escolhido para tal reflexão são duas reportagens do jornal Folha de São Paulo relacionadas à última edição do PISA em 2018. Mais do que divulgar os resultados e problematizar o futuro dos jovens brasileiros, o objetivo da prova é entender se os sistemas educacionais têm sido eficazes na formação de seus jovens. Para isso, realiza-se uma avaliação trianual com alunos de 15 anos, a fim de comparar o rendimento das economias que participam do PISA. Com o olhar da análise de discurso como fundação teórica, aponta-se o PISA como um dos instrumentos de objetivação que corrobora mudanças no atual cenário político da educação brasileira.

A REVIEW ON RADIO OVER FIBER SYSTEMS FOR LONG DISTANCE COMMUNICATION
Authors: Saffar Saman Ahmed Sulaiman
Published: August 2022

Recently wireless communication became very vital such that without it, it will be impossible to imagine the human life because it is extensively utilized in several civilian and military applications. These applications include transmission of various image types, high-quality video streaming, online meetings as well as novel bandwidth-intensive user applications like YouTube, Facebook, Netflix, etc. Because the radio signals have a limited bandwidth and are susceptible to atmospheric noise and distortion, they cannot provide bandwidth intensive applications and long distance communications. To provide the recipient of the radio signals to long distances, an advanced optical fiber technology known as Radio over Fiber (RoF) can be utilized faithfully. RoF is technology that modulates the light signal by radio signal and transmit it across a fiber optic link to extend the transmission and wireless access. Currently, this technology has become matured technology in terms of coverage, security and reliability. The RoF system has been implemented for the enhanced performance radio system having larger bandwidth for mobile communications. In addition, these systems have various advantages over traditional systems including higher bandwidth, easy Installation and Maintenance, lower attenuation, dynamic resource allocation, immunity against the RF interference and can transfer high frequency signals that support 5G and beyond 5G network technologies. This paper provides a comprehensive review on the currently existing RoF systems for long distance communication.

A Hipertermia Maligna (HM) é um distúrbio, que causa uma desordem na homeostase do cálcio intracelular, trazendo complicações como rigidez muscular, rabdomiólise, e temperaturas superiores a 40°C, é um distúrbio de baixa incidência, mas potencialmente fatal se não administrado o Dantroleno © com tempo hábil. O paciente pode desenvolver Hipertermia Maligna quando possui suscetibilidade genética, associada com a exposição dos agentes desencadeantes. Este trabalho teve por objetivo reunir informações sobre a incidência, fisiopatologia da doença, gatilhos farmacológicos, tratamentos disponíveis e diagnósticos clínicos e laboratoriais. Para isso foi realizado uma revisão  integrativa. Foram realizadas buscas nas bases de dados no Pubmed e SciELO utilizando os descritores e suas combinações nas línguas inglesa maglinant hyperthermia, general anesthesia, através do operador booleano AND. Foram selecionados artigos disponíveis na íntegra, partir do ano de 2010 até abril de 2021. Foram localizados 69 artigos. Após, leitura exploratório de título e resumo, foram excluídos 59 artigos. Após, a leitura completa, 7 artigos foram incluídos na revisão.  Destes artigos, foram extraídas informações sobre prevalência e incidência, fisiopatologia, gatilhos farmacológicos, tratamento e diagnóstico.  Este estudo conclui que a falta de conhecimento com relação aos sinais e sintomas, bem como os fatores de risco dificultam a identificação dos casos, tendo como consequência muitos casos subnotificados.

Spontaneous pneumothorax leading to pneumomediastinum, pneumopericardium and surgical emphysema is a benign condition. Progression to the development of epidural pneumatosis is rare. We report a 19-year-old man who presented with dyspnoea and swelling of the chest wall following a bout of cough. Bilateral subcutaneous emphysema was palpated on the anterior chest wall from the sternum to the midaxillary regions. His chest X-ray revealed subcutaneous emphysema and pneumopericardium. His computed tomography of the thorax to rule out life-threatening conditions revealed bilateral subcutaneous emphysema, pneumomediastinum, pneumo-pericardium and pneumothorax. He was transferred to the intensive care unit. An intercostal drainage tube was inserted in the left pleural cavity. The patient was followed up with repeat chest X-rays. The patient’s symptom got relieved and was discharged after day 9. Diagnosis of pneumomedia-stinum may not be as lamentable as it is seen. Close cardio-pulmonary monitoring is mandatory for complications and accompanying conditions. Most patients with uncomplicated spontaneous pneumomediastinum respond well to oxygen and conservative management. In this case, the patient’s symptoms and severe tachypnoea prompted the insertion of an intercostal drainage tube.

Circulating tumor cells (CTCs), secreted from primary and metastatic malignancies, hold a wealth of essential diagnostic and prognostic data for multiple cancers. Significantly, the information contained within these cells may hold the key to understanding cancer metastasis, both individually and fundamentally. Accordingly, developing ways to identify, isolate and interrogate CTCs plays an essential role in modern cancer research. Unfortunately, CTCs are typically present in the blood in vanishingly low titers and mixed with other blood components, making their isolation and analysis extremely challenging. Herein, we report the design, fabrication and optimization of a microfluidic device capable of automatically isolating CTCs from whole blood. This is achieved in two steps, via the passive viscoelastic separation of CTCs and white blood cells (WBCs) from red blood cells (RBCs), and subsequent active magnetophoretic separation of CTCs from WBCs. We detail the specific geometries required to balance the elastic and inertial forces required for successful passive separation of RBCs, and the use of computational fluid dynamics (CFD) to optimize active magnetophoretic separation. We subsequently describe the use of magnetic biosilica frustules, extracted from Chaetoceros sp. diatoms, to fluorescently tag CTCs and facilitate magnetic isolation. Finally, we use our microfluidic platform to separate HepG2-derived CTCs from whole blood, demonstrating exceptional CTC recovery (94.6%) and purity (89.7%)
Increasing the Sustainability of Biocatalytic Processes
Authors: Paradisi Francesca
Published: August 2022

The number of industrial processes which include one or more enzyme-mediated step is growing rapidly, together with our understanding of how biocatalysts can be adapted to efficiently perform chemical reactions, often only remotely related to their natural reactivity. While enzymes as naturally biodegradable molecules are the most sustainable approach to catalysis, a more global vision of the overall sustainability of enzymatic process must be considered. Here an insight of how sustainability can be further improved when enzymes are immobilized on solid supports is discussed.

Statistical Mechanics of Dimerizations and its Consequences for Small Systems
Authors: Zangi Ronen
Published: August 2022

Utilizing a statistical mechanics framework, we derive the expression of the equilibrium constant for dimerization reactions. An important feature arising from the derivation is the necessity to include two-body correlations between reactants' concentrations, reminiscent to those recently found crucial for binding reactions. However in (homo-) dimerizations, particles of the same type associate, and therefore, self-correlations are excluded. As a result, the mathematical form of the equilibrium constant differs from the well-known expression given in textbooks. For systems with large number of particles the discrepancy is negligible, whereas, for finite systems it is significant. Rationalized by collision probability between monomers, the bimolecular rate constant for dimer formation is proportional to concentration the same way correlations are accounted for. Another consequence of these correlations, is an inhomogeneous function behavior of system's properties when scaling-down the system to a regime smaller than the thermodynamic limit. All predictions are verified by MC and MD simulations.
Selectivity and Intrinsic Activity of Functionalized Cu Surfaces: Can the CO2 Reduction Reaction be Improved on Cu?

Published: August 2022

Cu is currently the most effective monometallic catalyst for producing valuable multi-carbon-based products, such as ethylene and ethanol, from the CO2 reduction reaction (CO2RR). One approach to optimize the activity and selectivity of the metal Cu catalyst is to functionalize the Cu electrode with a molecular modifier. We investigate from a data standpoint whether any reported functionalized Cu catalyst improves the intrinsic activity and/or multi-carbon product selectivity compared to the performance of bare Cu foil and the best single crystal Cu facets. Our analysis shows that the reported increases in activity are due to increased surface roughness and disappear once normalizing with respect to electrochemical surface area. The intrinsic activity generally falls below that of bare Cu foil, both for total and product-specific current, which we attribute to non-selective blocking of active sites by the modifier on the surface. Instead, we show that the modifier allows for easier diffusion of CO2 compared to H2O to the surface, leading to greater selectivity for CO2RR and C2+ products. As such, our analysis finds no catalyst for CO2RR that intrinsically outperforms bare Cu.

Published: August 2022

The recent advances in deep learning, generative modeling, and statistical learning have ushered in a renewed interest in traditional cheminformatics tools and methods. Quantifying molecular similarity is essential in molecular generative modeling, exploratory molecular synthesis campaigns, and drug-discovery applications to assess how new molecules differ from existing ones. Most tools target advanced users and lack general implementations accessible to the larger community. In this work, we introduce Artificial Intelligence Molecular Similarity (AIMSim), an accessible cheminformatics platform for performing similarity operations on collections of molecules called molecular datasets. AIMSim provides a unified platform to perform similarity-based tasks on molecular datasets, such as diversity quantification, outlier and novelty analysis, clustering, dimensionality reduction, and inter-molecular comparisons. AIMSim implements all major binary similarity metrics and molecular fingerprints and is provided as a Python package that includes support for command-line use as well as a fully functional Graphical User Interface for code-free utilization with fully interactive plots.
