Published: July 2024

Abstract
In this paper, we are concerned with the problem of stabilization of a degenerate parabolic equation with a Dirichlet control, evolving in bounded domain 𝓞 ⊂ ℝ
d
, d ≥ 2. We apply the proportional control design technique based on the spectrum of the linear operator which governs the evolution equation. The stabilizing feedback control, we design here, is linear, of finite-dimensional structure, easily manageable from the computational point of view.
The slowness of language, the speed of capital: conflicting temporalities of the “green transition” in the Swedish north
Authors: Nuottaniemi Andreas 
Published: July 2024

Abstract
Following substantial investments in battery production and fossil-free steel, a few select places in northern Sweden are currently undergoing rapid economic and cultural changes. The aim of this article is to explore the role language education plays for three different groups of (im)mobile subjects – refugees, labor migrants, and cosmopolitan elites – in the ongoing social transformations. By using the time-consuming and ideologically charged social practice of teaching and learning languages as a lens, it is argued that although framed as a sustainability project, the pace of the transformation is set by the accelerating logic of capitalism, posing a challenge to the democratic planning of inclusive local communities, as well as to societal subsystems characterized by much slower temporal regimes. Hence, although Sweden is committed to a “just transition” as part of the Paris Agreement, some are obviously benefiting much more than others from this transition. This paper further highlights the potentially high costs for the local communities that “win” the bids for the new green industries. Apart from considerable economic costs in the present, another result might also be increased social stratification and weakening social cohesion in the long term.

Published: July 2024

Abstract
Terahertz (THz) waves have exhibited promising prospects in 6G/7G communications, sensing, nondestructive detection, material modulation, and biomedical applications. With the development of high-power THz sources, more and more nonlinear optical effects at THz frequency and THz-induced nonlinear optical phenomena are investigated. These studies not only show a clear physics picture of electrons, ions, and molecules but also provide many novel applications in sensing, imaging, communications, and aerospace. Here, we review recent developments in THz nonlinear physics and THz-induced nonlinear optical phenomena. This review provides an overview and illustrates examples of how to achieve strong THz nonlinear phenomena and how to use THz waves to achieve nonlinear material modulation.

Published: July 2024

Abstract
Interference between the electric and magnetic dipole-induced in Mie nanostructures has been widely demonstrated to tailor the scattering field, which was commonly used in optical nano-antennas, filters, and routers. The dynamic control of scattering fields based on dielectric nanostructures is interesting for fundamental research and important for practical applications. Here, it is shown theoretically that the amplitude of the electric and magnetic dipoles induced in a vanadium dioxide nanosphere can be manipulated by using laser-induced metal-insulator transitions, and it is experimentally demonstrated that the directional scattering can be controlled by simply varying the irradiances of the excitation laser. As a straightforward application, we demonstrate a high-performance optical modulator in the visible band with high modulation depth, fast modulation speed, and high reproducibility arising from a backscattering setup with the quasi-first Kerker condition. Our method indicates the potential applications in developing nanoscale optical antennas and optical modulation devices.
Citizens’ exposure to predominant noise sources in agglomerations

Published: July 2024

Abstract
Environmental noise directive requires Member States to produce and periodically update strategic noise maps for agglomerates in order to evaluate citizens’ noise exposure before the action plan. Its ultimate purpose is to mitigate the highest or most harmful noise levels. Available tools do not provide a point-to-point indication of the predominant sources to be addressed by intervention on the sources by individual owners. Recently, noise source predominance maps were developed to show the predominant source at each point of the calculation grid of the strategic noise map by means of polygons and colors. Intensity noise source predominance maps were also developed to add the visualization of noise exposure levels by coloring the polygons according to a color scale. This work investigates their applicability in agglomerates and defines an additional indicator with the purpose of connecting the high levels of citizen exposure to its predominant source. The new approach provides an aid to administrations in identifying areas where singular noise mitigations would be truly effective in improving the citizen’s quality of life by ensuring a noticeable decrease in total noise while reducing exposure to the specific source.

Authors: Ren Yanjie , Zhang Yun , Li Xiaobing 
Published: July 2024

Abstract
Silver nanoparticles (AgNPs) can provide excellent, reliable, and effective solutions for anti-microbial, drug-loading, and other purposes due to their extraordinary physical, chemical, and biological characteristics. Different methods have been used in the synthesis and characterization of AgNPs, and AgNPs have been applied in various fields of biomedicine, including dentistry, oncology, diabetology, neurodegenerative disorders, and so on. However, the cytotoxicity of AgNPs has not been solved during their application, making them controversial. The aim of this review is to summarize the capabilities, synthesis, and characterization methods, and the application of AgNPs in various biomedicine fields. In addition, the toxicity of AgNPs is explicated, and the methods of enhancing the benefit properties and reducing the toxicity of AgNPs are demonstrated. In the end, the perspective of AgNPs’ research and application are proposed for the great potential in biomedicine contributing to human health.

Published: July 2024

Abstract

Objectives
The ‘Rational Laboratory Use Project’ (RLUP) was launched in 2018 by the Department of Examination and Diagnosis Services under the General Directorate of Health Services of the Republic of Turkey’s Ministry of Health. In this study, we aimed to determine the rate of implementation of RLUP in medical biochemistry laboratories, and to contribute to new regulations by collecting the information and opinions of the laboratory experts participating the survey.

Methods
Thirty questions were uploaded to an online survey tool (SurveyMonkey®, San Mateo, ABD). The first five were descriptive for laboratories. Among the remaining 25 questions, one is open-ended and addresses the various topics encompassed by the project’s scope.

Results
The questionnaire was completed by 202 medical biochemistry specialists, of whom 82.12 % reported that they did not implement autoverification. 55.65 % defined consultations in Hospital Management Information System (HIMS), but; 70.49 % were not using it actively. 57.69 % of the participants answered, “I agree” to the statement “I think RLUP is feasible”. It was observed that the specialists tried to implement rational laboratory practices partially depending on their laboratory capacity, hospital administration and Laboratory Information Management System (LIMS).

Conclusions
Increasing clinicians’ awareness could increase the success of this project, which might provide more effective diagnosis and treatment for the patient. In our view, actively involving stakeholders of the information management system, which is not under the direct control of laboratory professionals, in the RLUP will accelerate the development of the project.
Von Clinton lernen?
Authors: Dörr Nikolas 
Published: July 2024

Abstract
Hartz IV und die Agenda 2010 haben die deutsche Sozialpolitik verändert und eine zwei Jahrzehnte andauernde Debatte über Gerechtigkeit ausgelöst. Der Aufsatz untersucht den Einfluss des US-amerikanischen Workfare-Ansatzes während der Präsidentschaft von Bill Clinton (1992–2000) auf die Herausbildung und Entwicklung des neuen Paradigmas des aktivierenden Sozialstaats in der SPD. Nikolas Dörr zeigt, dass Clintons Wahlerfolge und Arbeitsmarktbilanz eine Vorbildwirkung für Mitte-Links-Parteien in Europa entfalteten, die sich schließlich im von Clinton und dem britischen Premier Tony Blair prominent propagierten Third Way widerspiegelte. Insbesondere Gerhard Schröder und Bodo Hombach forderten eine Orientierung am US-Beispiel, was in der SPD zu innerparteilichen Streitigkeiten führte. Auch wenn es letztlich nur zu wenigen konkreten Transfers kam, argumentiert der Beitrag, dass die Philosophie des aktivierenden Sozialstaats durch Clintons Sozialpolitik beeinflusst wurde.

Published: July 2024

The heterogeneity of the patient population and the lack of uniform approaches to periprocedural management highlight the importance of investigating the predictors of catheter ablation (CA) related complications in patients with atrial arrhythmias.Aim of the study: to identify risk factors for procedure-related (PR) and procedural sedation and analgesia (PSA)-related complications in patients with atrial arrhythmias.Materials and Methods. A single-center retrospective cohort observational study analyzed 2,340 electronic medical records (EMRs) from the I.I. Mechnikov NWSMU database from 2015 to 2022. A total of 1,793 EMRs were included in the study. All the patients underwent radiofrequency CA for atrial arrhythmia under procedural sedation and analgesia. The risk factors for PR- and PSA-related complications were identified using single-factor regression analysis and multivariate logistic regression with Jamovi 2.3.21 and IBM SPSS Statistics 26 software.Results. The PR- and PSA-related complication rates were 3.29% and 0.73 %, respectively. Hemopericardium/cardiac tamponade with an incidence of 1.45% and cerebral stroke/TIA documented in 1.17% of cases predominated among the PR complications. PSA-related complications included postoperative nausea and vomiting syndrome (0.22 %) and respiratory depression (requiring mechanical ventilation in 0.06% and non-invasive ventilation in 0.45%). Of all PR complications, 30.5% were documented in patients aged 70-74 years. BMI >30.0 kg/m2 (adjusted OR, 1.963; 95% CI, 1.09-3.36; P=0.023), age >69 years (adjusted OR, 3.081; 95% CI, 1.764-5.383; P<0.001), pain severity on the numerical rating scale (NRS) >3 points (adjusted OR, 4.317; 95% CI, 2.390-7.800; P<0.001), and previous CA procedure in the patient's history (adjusted OR, 10.276; 95% CI, 4.006-26.354; P<0.001) were found to be risk factors for the development of PR complications, whereas BMI >35 kg/m2 (adjusted OR, 4.955; 95% CI, 1.485-16.535; P=0.009) and duration of CA procedure >142 min (adjusted OR, 11.070; 95% CI, 2.440-50.228; P=0.002) were found to be risk factors of PSA complications.Conclusion. The following independent predictors of CA-related complications were identified: patient-related factors such as BMI >30.0 kg/m2 and age >69 years, as well as procedure-related factors such as duration of CA >142 min, history of CA, and pain intensity >3 NPRS points.

This research study focused on the primary freshwater surface sources of Khyber Pakhtunkhwa (KP) province, Pakistan—Swat and Kabul rivers. The study aimed to assess microplastic (MP) contamination of fish in the Swat and Kabul rivers. Understanding this contamination is vital for evaluating the environmental and health risks associated with consuming contaminated fish and contributing to the ongoing conservation efforts. The study’s objective was to investigate the presence of MPs in the gastrointestinal tracts (GIT) of fish and to delineate the identified MP types. Samples of local dominant fish (Schizothorax plagiostomus [Swatay] and Racoma labiata [Chunr], Cyprinus carpio [Common Carp], and Clupisoma naziri [Sher Mayai]) were collected, and their body weight and length assessed to gauge the overall health. The GIT samples were processed, digested and filtered before microscopic examination to detect MPs. Subsequently, the identified MPs were subjected to attenuated total reflectance–Fourier transform infrared spectroscopy for characterization by analyzing their absorption bands. Results of the study showed the presence of MPs in fish samples, predominantly identified as polyethylene (PE), with polypropylene (PP) being the subsequently prevalent plastic type, which manifested fish contamination with MPs. The study revealed MP pollution in both Swat and Kabul rivers, with fish ingesting these particles. This poses potential health risks for fish and health of the ecosystem.

Published: July 2024

This research work is part of a project to develop the natural substances of higher basidiomycetes from Algeria’s forest. This study aimed to evaluate the bioactive compounds of higher fungi, by quantifying phenols and flavonoids using spectrophotometry. The assay, showed that the highest quantity of flavonoids was recorded in the extract of Trametes quercina (10.27 ± 0.015 mg QE/g), followed by Suillus mediterraneensis (7.82 ± 0.011 mg QE/g). For phenols, amount of 442.23 and 432.88 mg GAE/g were respectively found in Lactarius zonarioides and S. mediterraneensis. In addition, TLC chromatographic screening was carried out for the first time in order to select higher basidiomycetes containing secondary metabolites. The results reported that all the basidiomycete extracts are rich in phenols, tannins and flavonoids with a similarity of secondary metabolites between the different extracts. Following these chemical investigations, eight extracts showing a phyto-stimulating effect were selected for analysis by high-performance liquid chromatography (HPLC). The presence of flavones and flavonols was detected: Flavones were found in Agaricus bisporus, Boletus sp., Pleurotus dryinus, S. mediterraneensis, Coprinus atramentarius, T. quercina and Xerocomus sp. On the other hand, flavonols were found in C. atramentarius, Pleurotus ostreatus and P. dryinus. Additionally, tannic acid was found in S. mediterraneensis, chromatographic profiles show that basidiomycete extracts produce a wide range of secondary metabolites, with many compounds common to all extracts. The study of plant growth enhancement by extracts of basidiomycetes on eggplant, in hydroponic conditions, is a novelty. The chemical study confirmed that these extracts do indeed contain a diversity of bioactive products that contribute to increasing plant yield, thus offering strong agricultural potential.

Seed dormancy is a major impediment for the production of Salvia officinalis L. (sage) seedlings. This study aims to test seed priming methods to break the dormancy of sage seeds in controlled conditions. Seeds were subjected to four treatments respectively hydropriming, magneto-priming, electro-priming and control with no seed priming techniques. During germination development stage all parameters were registered according to BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie) standardized scale. Daily assessments were made, germination indices were calculated, new germination secondary stages were observed and described, and daily range for each secondary stage were obtained. All priming methods had different effect on sage seeds. The hydropriming treatment was the most effective with 70% seeds germinated in 10 days. Sage seeds from magneto-priming determine more than 50% seeds to germinate in only 8 days. Control and electropriming treatment showed a similar value of seed germination, set around 64-65%. In control, electro- and hydropriming treatments are necessary 6 days for the achievement of more than 50% seed germination, while for magneto-priming are necessary 8 days. Hydropriming has the highest germination index, significantly higher than control and magneto-priming. During the germination, hydropriming shows a gradual transition of seeds from one BBCH sub-stage to another, while electro- and magneto-priming induce a heterogenous variation through the entire process. Overall, the hydropriming treatment registered better results of sage germination compared to the control treatment.
Joint use of sodium silicate and polysaccharides in the flotation of talcose copper-nickel ores
Authors: Lavrinenko A. A. , Kuznetsova I. N. , Golberg G. Yu. , Lusinyan O. G. 
Published: July 2024

The paper considers the combined effect of polysaccharides (carboxymethyl cellulose and carboxymethyl starch) with sodium silicate in the f lotation of talcose copper-nickel ore. The analysis of the f lotation results and the assessment of hydrophobicity and surface charge of minerals showed that the composition of carboxymethylated polysaccharides and sodium silicate hydrophilizes the talc surface more effectively than each of the reagents separately. Moreover, sodium silicate alone hardly depresses the talc surface at all. The depression of f lotation-active silicates is effective when polysaccharide and sodium silicate are sequentially supplied. Under these conditions, sodium silicate makes a significant contribution to increasing the negative charge on the talc particles surface. The effect is more pronounced for compositions with starch, characterized by a lower degree of substitution compared to cellulose. It results in a significantly reduced recovery of f lotation-active magnesium-containing silicates and a slight decrease in sulfide recovery. To determine the features of the mechanism of talc and sulfide minerals depression in f lotation, we performed calculations using the extended DLVO theory based on the obtained values of the zeta potential and force of detachment. We established that sulfide minerals have no potential barrier preventing their interaction with an air bubble, regardless of the compositions of the studied depressants used. We propose the following interaction mechanism: when sodium silicate is supplied first, the talc basal surface is very insignificantly hydrophilized as SiO(OH)– ions are not easy to fix. On the contrary, when the carboxymethylated polysaccharide is supplied first, significant hydrophilization of the talc surface with carboxyl groups occurs due to the hydrophobic interaction between the corresponding regions of the macromolecule and the talc basal surface.
