Authors: Stampoltzis Aglaia , Paradisi Anastasia E. , Theodosakis Dimitrios
Published: September 2023

Dyslexia is traditionally regarded as a disability which has an impact on the learning process of reading, spelling and writing. This study attempts to explore the character strengths, flourishing, resilience, and perceptions of professional success and satisfaction of 477 Greek adults. The sample consisted of 30 adults with an official diagnosis of dyslexia, 103 adults who scored above the threshold limit in the Dyslexia Checklist, and 344 adults who did not report any leaning difficulty. The following instruments were employed in the study: the Brief Resilience Scale, the Flourishing Scale, and subscales of the Values in Action Inventory of Strengths 120 (creativity, perseverance, social intelligence and teamwork). The results show that the dyslexic group scored higher in creativity and teamwork in comparison to the control group. No statistical differences were observed in professional success and satisfaction between the groups. Level of education seems to correlate with creativity. The prediction models showed a negative correlation of social intelligence with suspected dyslexia and a very low prediction of flourishing and resilience on the basis of dyslexia status. Positive traits of dyslexia are worth further study. Identifying strengths among people with dyslexia might be helpful for implementing new educational interventions and strategies.

Authors: Gomes A. Rui , Fontes Liliana , Costa-Figueiredo Ana Cristina
Published: September 2023

Life skills are personal resources that can be trained and applied in a specific situation and transferred to other contexts. The growing body of research has shown that intervention programs produce positive results in learning and transferring life skills. Nonetheless, there is a need to clarify the efficacy of life skills training, namely the theoretical background of life skills interventions and how to organize the intervention programs. This paper attempts to overcome these gaps of literature by providing a conceptualization of life skills into two axes: typology (cognitive to physical continuum) and function (personal and interpersonal). Also, it is presented a theoretical model of life skills training that establishes the stages and principles of life skills acquisition, the variables that influence training, and the measures and hypotheses that can be used to evaluate the efficacy of life skills training. In sum, we clarify the actual challenges of life skills training and provide indications on how to apply and evaluate the efficacy of the intervention.

Published: September 2023

Background: Catheter-associated urinary tract infections (CAUTI) constitute a significant portion of healthcare-associated infections. Using antiseptic for routine daily perineal care of patients with IUC may reduce CAUTIs.
Aim: This study aimed to examine antimicrobial photodynamic inactivation (aPDI) against clinical isolates for use in the daily perineal care of patients with IUC. In addition, it was also aimed to compare the antimicrobial activities of aPDI and 0.1% chlorhexidine gluconate.
Methods:  In this in-vitro study, cationic porphyrin derivatives (CPDs) were used as photosensitizers in the experiments. CPDs, named PM, PE, PN, and PL were synthesized by the researchers. A diode laser device emitting light with a wavelength of 450 nm (blue light) was used as the light source. Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli and Klebsiella pneumoniae with multidrug-resistant (MDR) properties and Candida albicans were used.  Photosensitizer (PS), aPDI, light (L), and control (C) groups in aPDI experiments; control (C) and chlorhexidine gluconate 0.1% groups were used in the chlorhexidine gluconate experiments. Survival was calculated based on CFU/mL in the control group.
Results: In experiments, combinations of 25 J/cm² with 6.25 and 3.125 µM PM, PE reduced E. coli, K. pneumoniae, MRSA, and C. albicans survival in the range of 8.70 to 11.53 log₁₀. In aPDI experiments performed with 6.25 and 3.125 µM PN and PL concentrations at the same energy density, reductions in the range of 4.41 to 0.17 log₁₀ were observed in all four clinical isolates. In experiments where 1.5625 µM concentration was used, survival decreased in the range of 8.29 to 10.87 log₁₀ in PM and PE, while antimicrobial activity was limited in PN and PL. In the 0.1% chlorhexidine gluconate experiments, the survival reduction in all four clinical isolates ranged from 8.87 to 10.24 log₁₀.
Conclusion: For PM and PE, a very strong aPDI was obtained in C. albicans, E.coli, K. pneumoniae, and MRSA at low concentrations and energy density. The same antimicrobial activity was found in experiments using 0.1% chlorhexidine gluconate. In this context, we would like to inform you that aPDI to be performed with a combination of 25 J/cm² at 6.25 and 3.125 µM concentrations of PM and PE has the potential to be an antiseptic in the daily perineal care of patients with IUC.

Published: September 2023

In chronological order, the reaseach results of Department of heterogeneous acid-base catalysis at Institute for sorption and endoecology problems in 2003-2023 are described. It relates to the synthesis, study and application of solid superacids WO3/ZrO2, WO3/ZrO2-SiO2, ZrO2-SiO2-Al2O3, ZrO2-SiO2-SnO2, as catalysts, in vacuum gas oil cracking, alkylation of isobutane with isobutanol, acylation toluene, oligomerization of tetrohydrofuran, acylation of methyl tert-butyl ether and other. Some study deals with a search of the correlations between of acid site strength of a catalyst and its activity, in particular, in dehydration reaction of C2-C4 alcohols, and the correlations between ability of primary and secondary alcohols to dehydrogenation and oxidation and their chemical shifts δ (R17OH) and δ (R13СОH ). For the first time, the values of Hammett's acidity function have been measured at elevated (up to 200 °C) temperatures for solid acids. In particular, for H-Y faujasite, H0 reaches superacidic value H0 at 160 °С. Since 2010, the main focus has been on the catalytic conversion of renewable raw materials, mainly bioalcohols (ethanol, glycerol) and C6 carbohydrates, into important products of organic synthesis (ethyl acetate, 1,1 diethoxyethane, n-butanol, propylene glycol, alkyl lactates, lactide, glycolide). In cooperation with “Techinservice Manufacturing Group”, new processes for obtaining ethyl acetate, 1,1 diethoxyethane, n-butanol from bioethanol and racemic lactide from glycerol were developed. Also, new technologies for obtaining propylene oxide from propylene and hydrogen peroxide (НРPОа-process), vapor phase hydrogenation of the pyrolysis C4-5 fraction, and direct high-temperature chlorination of ethylene to vinyl chloride have been developed for Kalush “Karpatnaftochim” plant.

The vapor-phase oxidation of mixtures of propylene glycol with methanol and ethanol to methyl and ethyl lactate, respectively, on supported CeO2/Al2O3 catalyst at 210-2500С was investigated. Air oxygen and a flow reactor with a fixed catalyst bed were used. A 20% solution of propylene glycol in alcohol was supplied to the reactor inlet. Oxidation of propylene glycol in the presence of methanol occurs according to the overall reaction CH3CHOHCH2OH +O2 + СН3OH = CH3CHOHCOOСН3 +2H2O. First, hydroxyacetone is formed, which is further oxidized to pyruvic aldehyde, which adds alcohol to form a hemiacetal. Next, this hemiacetal is rearranged according to Cannizzaro into methyl lactate. At 2200C and catalyst load < 2 mmol PG/gcat/h, the selectivity for methyl lactate reached 70 wt.% at 100% propylene glycol conversion. In the presence of ethanol, the formation of a significant amount of acetaldehyde and its aldol condensation products, as well as the formation of diethoxyethane, was observed. Therefore, the selectivity for ethyl lactate at 100% propylene glycol conversion did not exceed 45%.

The article noted that the pollution of surface water bodies by oil products as part of wastewater in Ukraine in 2020 reached 246.6 tons. For aquatic organisms, oil and oil products are highly toxic substances and belong to the group of nerve poisons. Most of the wastewater generated today in industry is subject to purification from petroleum products before discharge into the environment, however, existing purification technologies do not fully meet modern requirements. Electrochemical cleaning methods have a number of significant advantages over reagent methods: the salt content in water does not increase, which plays an important role in the organization of circulating water supply systems; less sediment is formed; the technological scheme of cleaning is simplified; there is no need to organize a reagent farm; small production areas are required for the placement of electrochemical treatment plants. The operation of electric cleaning plants is simple due to their high manufacturability and the possibility of automation. As a result of research, the optimal conditions for electroflotation water purification from oil products have been determined. The dependence of the degree of purification on the material of the anode, the pH of the initial solution and the current density was studied. It was established that the best effect is achieved in the pH range of 5-7 at current densities of 0.25-0.3 A/dm2. In the presence of sulfates, cleaning proceeds better than in the presence of chlorides, since Cl– ions intensify the point breakdown of the anode material. Among the studied materials, 08кп steel can be recommended as an anode. The nature of the electrochemical dissolution of 08kp steel depending on its preliminary treatment and the effect of such treatment on the degree of purification of water from petroleum products was studied. It is shown that when adding sulfanol НП-3 with flocculant ВПК-402 to oil-containing water, a water-insoluble complex is formed, which contributes to a more complete purification of water from oil and oil products.

New proton exchange membrane based on polyimide Matrimid® (PI) and hydrophobic protic ionic liquid, 1-methylimidazolium bis(trifluoromethylsulfonyl)imide (MIM-TFSI), has been prepared by casting from methylene chloride/dimethylformamide solution. Infrared analysis revealed physicochemical interactions between 1-methylimidazolium cations and imide groups of PI. The results of mechanical testing indicate significantly reduced tensile strength of PI/MIM-TFSI composite membrane compared to neat polymer. Moreover, the dynamical mechanical analysis results revealed sharp drop in storage modulus (E´) of the polymer film above 60 °C. To improve the elastic properties of the membrane, PI was successively cross-linked with polyetheramine Jeffamine® D-2000 (10 mol. %) in methylene chloride/dimethylformamide solution, as well as in solid film at 100 °C. This approach allowed to prepare PI/Jeffamine/MIM-TFSI (70 wt. %) composite film which has an acceptable E' value of 210 MPa at 140 °C. According to thermal gravimetric analysis data, PI/Jeffamine/MIM-TFSI composite has a thermal degradation point (i.e. 5 % weight loss) of 286 °C. The ionic conductivity of PI/Jeffamine/MIM-TFSI composite membrane is around 10–4 S/cm at room temperature and reaches the minimal level of 10–3 S/cm, required for fuel cell applications, above 100 °C. Overall, the results of this study indicate that the cross-linking of polyimide Matrimid with flexible polyetheramine Jeffamine is an efficient approach for preparing dense composite membrane with high content of the protic ionic liquid. Such polymer-electrolyte membrane has the reasonable combination of good stiffness, thermal stability, and ionic conductivity and therefore is a promising candidate for use in fuel cells operating at elevated temperatures in water-free conditions.

Personality is a term that comes from the Latin word "persona" which means "mask", or also from the Latin word "personare" which means to sound through. Meanwhile, in Arabic, personality is called syakhshiyah. In Arabic lexicology, the term nafsiyah is also known which comes from the word nafs; iniyah (aniyah) from the word ana, and the term khuluqiyah or "akhlaq" which is more widely used in classical Islamic literature. These words are similar to the word syakhshiyah, but are unique. Therefore, this research will discuss personality concepts from an Islamic perspective.

Published: September 2023

The European Society of Cardiology (ESC) 2019 guidelines propose a novel diagnostic algorithm for examining stable patients with suspected coronary artery disease (CAD). In retrospective analysis of previous studies, a new pretest probability scale was validated and a method for assessing clinical probability of obstructive CAD was proposed, taking into account risk factors and coronary artery calcium score. The results were studied in the EURECA multicenter registry, and the ESC-2019 diagnostic algorithm was compared with other known algorithms. The review details the results of these recently published studies, emphasizing the role of calcium score assessment in identifying low-risk patients for obstructive CAD. The review also considers publications using computed tomography coronary angiography as a "gatekeeper" among patients selected for invasive coronary angiography. The results obtained showed the effectiveness of novel diagnostic strategies in increasing the detection rate of obstructive CAD. However, clinical outcomes of any diagnostic algorithm are few and require further study, as well as their cost-effectiveness.

Aim. To determine the incidence and predictors of cardiovascular events in onpump cardiac operations in modern practice.

Material and methods. The study included 200 patients who underwent various elective cardiac surgical interventions. Cardiovascular events (CVEs) were determined within 30 days from the operation, according to medical records and autopsy protocols. We identified major CVEs (cardiovascular death, stroke, myocardial infarction) and minor CVEs (angina pectoris, significant ventricular arrhythmias, atrial fibrillation or flutter episodes, AV conduction disorders, etc.). A comprehensive preoperative examination was performed, including an extended echocardiography protocol and coronary angiography.

Results. In 101 patients (50,05%), various CVEs were identified: 4,0% had major CVEs and 46,05% had minor CVEs and various non-cardiac complications, while perioperative mortality was 2,0%. Most ischemic CVEs, as well as most intracardiac conduction disorders, were registered during the first 3 days after surgery. In contrast, episodes of atrial fibrillation/flutter occurred 2-7 days after the intervention. There were following preoperative examination parameters with the highest prognostic value: history of heart failure, age >65 years, history of myocardial infarction, occlusion of at least one coronary artery, and diabetes.

Conclusion. The data obtained indicate the high efficiency of current surgical and anesthetic technologies, which lead to relatively low risk of severe and fatal events. The parameters of the preoperative examination, which determine the increased risk of intervention, are highlighted.

Cardiovascular diseases (CVDs) are the leading threat to the population health in the Russian Federation (RF), ranking first in the mortality structure. Demonstration of the economic impact of CVD is a rationale for investing in prevention and treatment. The economic damage caused by CVD in 2016 in the RF amounted to RUB 2,7 trillion, which is equivalent to 3,2% of gross domestic product (GDP). In the structure of damage by diseases, coronary artery disease occupies a leading position — RUB 1 trillion or 1,3% of GDP, while cerebrovascular diseases, stroke and myocardial infarction — RUB 560, 424 and 213,2 billion, respectively. Evaluation of cardiovascular prevention measures is not an easy task because the effect develops over a significant period of time. At the same time, various processes can affect the effect. The RF analysis showed that the potential economic effect from anti-tobacco and anti-alcohol measures, reducing salt consumption and increasing physical activity will be RUB 8,1 trillion in labor productivity increase over 15 years (equivalent to 7,8% of GDP in 2018), with most of the effect from the prevention of CVD deaths. Analyzing the economic impact of CVDs, preventive and curative measures provide a rationale for investment and is an important step in making informed decisions.

Aim. To obtain extended data on the impact of collateral circulation on the recovery of left ventricular (LV) function after recanalization of chronic coronary total occlusion (CTO), especially in patients with reduced left ventricle ejection fraction (LVEF).

Material and methods. This single-center, prospective, non-randomized study included 20 patients with single-vessel CTO with reduced LVEF (<50%), confirmed by magnetic resonance imaging (MRI), who underwent successful recanalization. All patients were divided into 2 groups depending on the severity of collateral circulation. After 1, 3 and 6 months, MRI was repeated to assess LV function recovery.

Results. All patients had prior myocardial infarction, while in 70% of cases — in the area of the occluded artery. A previous attempt to recanalize CTO was noted in 30%. The mean baseline LVEF according to echocardiography was 38,80±6,72%. The most common target vessel was the right coronary artery (n=17, 85%), followed by the circumflex and anterior descending arteries — 1 (5%) and 2 (10%) patients, respectively. In the group with high collateral circulation, the initial LVEF according to MRI was higher compared to the group with mild collateral circulation (35,8±7,33% vs 30,7±8,82%, p=0,17). After 6 months, MRI showed significant changes in end-diastolic volume (from 226±71,1 ml to 203±55,2 ml) and LV endsystolic volume (from 153±72,8 ml to 118±57,6 ml), as well as mean increase in LVEF by 3,3%, 4,8% and 5,2% at 1, 3 and 6 months, respectively (p=0,01 compared with baseline). The predictors of LVEF recovery in multivariate regression analysis were the initial LVEF according to MRI, and the filling rate of distal CTO bed on coronary angiography (R2=0,63).

Conclusion. Successful percutaneous coronary intervention with CTO improves LV function in patients with ischemic cardiomyopathy, regardless of the degree of collateral circulation. LV function recovery generally occurs within 3 months after revascularization.

Aim. To compare cardiac magnetic resonance imaging (MRI) parameters with known prognosis determinants in patients with pulmonary hypertension (PH).

Material and methods. This prospective single-center study included 60 patients with PH aged 21-72 years. Cardiac MRI, right heart catheterization, echocardiography, N-terminal pro-brain natriuretic peptide (NT-proBNP) and 6-minute walk test (6MWT) were assessed at baseline.

Results. Significant correlations between invasive hemodynamic parameters, NTproBNP and cardiac MRI parameters were confirmed. There were no significant correlations between the right ventricular (RV) contractility, RV volume and 6MWT distance, the functional class of PH. Cardiac MRI values allowed us to reliably separate patients at low risk from those at intermediate and high risk according to the 2015 ESC/ERS score. According to multivariate regression analysis, the right ventricular end systolic volume index >54 ml/m2 (hazard ratio, 0,2; 95% confidence interval, 0,05-0,9; p=0,004) and class 3-4 PH (hazard ratio, 0,2; 95% confidence interval, 0,07-0,8; p=0,026) remained independent predictors of mortality.

Conclusion. The use of cardiac MRI in low-risk patients can significantly improve the early detection of right ventricular myocardial dysfunction and contribute to the timely optimization of PH-specific therapy. During monitoring patients with PH, cardiac MRI has the potential to reduce the need for repeated invasive investigations.
Clustering what Matters: Optimal Approximation for Clustering with Outliers

Clustering with outliers is one of the most fundamental problems in Computer Science. Given a set X of n points and two numbers k, m, the clustering with outliers aims to exclude m points from X and partition the remaining points into k clusters that minimizes a certain cost function. In this paper, we give a general approach for solving clustering with outliers, which results in a fixed-parameter tractable (FPT) algorithm in k and m—i.e., an algorithm with running time of the form f(k, m) · nO(1) for some function f—that almost matches the approximation ratio for its outlier-free counterpart. As a corollary, we obtain FPT approximation algorithms with optimal approximation ratios for k-Median and k-Means with outliers in general and Euclidean metrics. We also exhibit more applications of our approach to other variants of the problem that impose additional constraints on the clustering, such as fairness or matroid constraints.
Copulas, possession, and the temporary-permanent distinction in Mashi: Evidence for decompositional HAVE
Authors: Finholt Aron
Published: September 2023

It is cross-linguistically common to find a distinction between “temporary” vs. “permanent” states in copular verbs, e.g., Spanish estar and ser (see Deo et al. 2017). In Mashi [shr] (Bantu, JD53; Maho 2009), a similar temporary-permanent distinction holds not only of the two copular be-verbs in the language, -li (temporary state) and -ba (permanent state), but also of the two possessive have-verbs, -dwiire and -jira; -dwiire indicates temporary possession, while -jira instead indicates permanent possession. This parallelism provides a novel argument in favor of a decompositional approach to possessive verbs (Freeze 1992, Kayne 1993, Harley 1998). The analysis is further supported through patterns of allomorphy where HAVE is realized in its decomposed form, BE + comitative, in Mashi. I analyze the patterns using a Spanning Insertion analysis (Williams 2003, Svenonius 2012, 2016, Merchant 2015).

The purpose of the study is to assess the quantitative state of water resources in 50 European countries based on the FAO-Aquastat database on average annual indicators, to rank them, to assess the external dependence of water resources of countries, to identify countries with water deficit. According to the Falkenmark water stress indicator (m3/year/person), European countries are ranked as follows: a) the state of water resources is stable (>2500 m3/year per person) – Iceland, Norway, Russia, Croatia, Finland, Serbia, Latvia, Sweden, Georgia, Slovenia, Ireland, Romania, Hungary, Bosnia and Herzegovina, Albania, Estonia, Slovakia, Austria, Lithuania, Portugal, Switzerland, Greece, Belarus, Luxembourg, Kazakhstan, Netherlands, Andorra, Ukraine, Azerbaijan, France, Italy, North Macedonia , Moldova, Bulgaria, Armenia, Turkey; b) existing water vulnerability (1700-2500 m3/year per person) – Spain, Great Britain, Germany; c) existing water stress (<1700 m3/year per person) – Belgium, Poland, Czech Republic, Denmark; d) existing water deficit (<1000 m3/year per person) – Cyprus; e) current absolute water deficit (< 500 m3/year per person) – Malta. The countries of Europe, the formation of water resources of which is more than 50% outside their borders, include Portugal, Latvia, Croatia, Ukraine, Luxembourg, Slovakia, Azerbaijan, Romania, Moldova, the Netherlands, Hungary, Serbia. The range of KZ for the list of these countries is from 50.9% (Portugal) to 94.8% (Serbia). The total water withdrawal in the EU is about 353 km3/year, which means that 10% of the total fresh water is withdrawn. In Europe, the majority of water is used from surface water bodies – 74% of total water withdrawals are from rivers and reservoirs, and 24.5% from groundwater. Water withdrawal rates are highest during the growing season. Water is used in agriculture (44%), industry (40%) and household purposes (16%). Increased droughts due to climate change exacerbate seasonal water scarcity. Abnormal heat in Europe was observed in 2003, 2018, 2019, 2022.
