It is necessary to begin with the native nest, the settlement, region and to join state structures with a sound basis. And what we have: looted land resources, subsoil, historical monuments, forests, protected areas, rivers and lakes, and most sadly - we lose human professional resources
Redefining Standard Measurement Uncertainty
Authors: Possolo Antonio , Bodnar Olha
Published: June 2022

The Guide to the Expression of Uncertainty in Measurement (GUM) defines standard measurement uncertainty as the standard deviation of a probability distribution that describes the uncertainty associated with an estimate of the measurand, and defines expanded uncertainty as a multiple of the standard uncertainty. Monte Carlo methods can produce the expanded uncertainty for 95 % coverage as one half of the length of the interval whose endpoints are the 2.5th and 97.5th percentiles of the probability distribution of the estimate of the measurand (when this distribution is approximately symmetrical). This creates an opportunity for a paradox to arise: that the standard uncertainty, defined as a standard deviation, can be larger than the expanded uncertainty. We provide an example involving real measurement data where this paradox arises with high probability, and then offer a new definition of standard uncertainty that agrees numerically with the conventional definition in “normal” cases, but that is still reliable in “abnormal” cases.

The current study assessed health risks posed by exposure to metals from the consumption of Baltic Sea trout (Salmo trutta L.). Concentrations of essential minerals in sea trout muscles were determined and compared with the physiological requirements of these minerals in Polish nutrition standards, recommended dietary allowances (RDA), and estimated average requirements (EAR). Chemical analyses indicated that sea trout was rich in phosphorus, calcium, magnesium, sodium, and potassium. The pattern significance gradation of the element concentrations was as follows: P>Ca>Mg>Na>K>Fe>Zn>Cu>Se>Mn>Co. Sea trout consumption can provide a considerable portion of the RDA of copper, magnesium, phosphorus, calcium, iron, and zinc. The ranking order of the mean toxic element concentrations in sea trout muscle tissues was As>Pb>Cd>Hg. Potential risk estimated with the hazard quotient (HQ) indicated that most metals posed no health risk because they did not exceed reference doses at HQ < 1. For carcinogenic and non-carcinogenic effects, the maximum allowable rates of sea trout consumption were sufficiently high to ensure human health. According to these data, the consumption of farmed sea trout from the Baltic Sea in the northern region of Pomerania, Poland did not pose a risk to human health.

Published: June 2022

We have studied the problem of homogenous, isotropic non-local couple stress micropolar thermoelastic solid in the absence of body forces, couple density and heat resources. The reflection and transmission of waves at the interface of two distinct media have been investigated. It is observed that amplitude ratios of various reflected and transmitted waves are functions of wave number of incident waves and are affected by the non-local parameter of thermoelastic solid.
Heat Transfer in Oscillating Flow Through Porous Medium with Dissipative Heat
Authors: Guria M.
Published: June 2022

In this paper, heat transfer in flow between two horizontal parallel porous plates through a porous medium when the upper plate oscillates in its own plane has been analyzed taking into account the effect of viscous dissipation. An increment in the Prandtl number or Reynolds number results in an increment of the temperature profile. With an increase in viscous dissipative heat the temperature distribution decreases.

In this work, a numerical study of a sharply expanding highly swirling flow is carried out using v2-f models based on the Comsol Multiphysics 5.6 software package and a two-fluid turbulence model. The results obtained are compared with known experimental data with different pipe diameters. The purpose of this work is to test the ability of models to describe anisotropic turbulence. It is shown that the two-fluid model is more suitable for studying such flows.
Coronary Angioplasty and Stenting in Acute Coronary Syndromes Using Very Low Contrast Volume and Radiation Dosage Improves Renal and Cardiovascular Outcomes
Authors: Arokiaraj Mark Christopher
Published: June 2022

Aim: To demonstrate that in patients with acute coronary syndrome (ACS), using Cordis 6F Infiniti diagnostic catheters for angioplasty may represent a safe alternative associated with lower contrast volume and radiation dosage, improving cardiovascular and renal outcomes.

Material and Methods: In 1,800 patients with ACS (2,331 lesions/2,603 stents), angioplasty was performed with Cordis 6F Infiniti Thrulumen diagnostic catheters. Primary angioplasty was performed in 545 cases, and only balloon angioplasty in 67 patients. All procedures were performed through the femoral route, and switch-over to the radial route was made in 5 cases due to associated aortic/iliac obstructive lesions. Iodixanol was used in 76% of cases, and tirofiban in 99% of cases with adjusted dosages based on creatinine values. The mean contrast volume used per patient was 28 mL (± 6 mL) including the angiogram prior to the angioplasty.

Results: The median fluoroscopy time was 4.4 min (IQR 3–6.8), the mean fluoroscopy time was 5.59 min (± 0.28), the median dose-area product or kerma-area product was 1,507 µGym2 (IQR 918–2,611), median total or cumulative dose including backscatter was 2,702 µGym2 (IQR 1,805–4,217), and the median cumulative skin dose was 468 mGy (IQR 296–722). Groin hematoma was seen in 7 cases, proximal mild edge dissection in the deployed stent in 3 cases, and acute in-hospital stent thrombosis in 7 cases. In total, 33 deaths were registered and 19 of these patients had cardiogenic shock, of which 11 subjects were late presenters. Three patients died after discharge due to possible acute stent thrombosis.

Conclusions: Angioplasty and stenting can be performed safely in patients with acute coronary syndromes using Cordis 6F diagnostic catheters. The procedure was associated with a very low volume of contrast and radiation dose, leading to improved clinical outcomes..

Citizens’ Attitudes to Nudges in the Maintenance of Public Spaces and Waste Management

Published: June 2022

Behavioural interventions, or nudges, can be seen in public policy as a tool to help local governments in a variety of areas. The main advantages of nudges include the low costs associated with their implementation and, on the other hand, the relatively high effect if the factors acting on individuals are correctly identified (e.g., the salience factor associated with the individual’s bias, social norms, or how the individual’s surroundings react). Before implementing a behavioural intervention, it is necessary to know, the motives or causes of the behaviour of the inhabitants in the city.

The paper is specifically devoted to the nudges that can be implemented in the maintenance of public spaces and waste management. The aim of the paper is to find out the attitudes of citizens towards the problems in maintenance of public spaces and waste management caused by human behaviour as well as possible solutions in the form of selected types of nudges.

The paper identified several reasons that can contribute to an increase the level of citizen participation in waste separation and improve the quality of maintenance of public spaces, such as where the nudging is implemented (factor of affect), attractiveness of the nudge (factor of silence) and the commitment of individuals. The selected behavioural interventions show that there is a willingness on the part of the citizens in a local municipality to accept nudges and the citizens tendency to change behaviour in the desired way.
