The nurse shortage crisis is caused by the high turnover of nurses related to management practices that were not running optimally. Anticipatory efforts are critical to increase nurse retention by increasing self-motivation and work environment to increase job satisfaction on nurses as an impact. This study aimed to provide empirical evidence of the effect of self-motivation and work environment on nurse retention with job satisfaction as an intervening variable. This research used quantitative research with survey methods using questionnaires. The unit of analysis was a group of nurses PK 1 as many as 61 people. Data analysis used path analysis with multiple linear regression as the data analysis technique. Results showed that self-motivation and work environment had a significant effect on nurse retention with job satisfaction as an intervening variable. The variables of self-motivation and work environment each had a significant effect on job satisfaction. The variables of self-motivation, work environment, and job satisfaction each had a significant effect on nurse retention. The findings indicate that employees are dissatisfied with the work environment, both physical and non-physical, as well as the compensation and rewards provided by the company. We suggest to the hospital to give awards in the form of bonuses or incentives to nurses in accordance with work assessments. We also suggest for further research to examine more deeply about the four variables in this study with other research subjects to compare with the results of the research

Drug uptake and distribution through cell–receptor interactions are of prime interest in reducing the adverse effects and increasing the therapeutic effectiveness of delivered formulations. This study aimed to formulate silver nanoparticles (AgNPs) conjugated to somatostatin analogs for specific delivery through somatostatin receptors (SSTRs) expressed on cells and by nebulizing the prepared AgNPs formulations into lung cells for in vivo application. AgNPs were prepared using the citrate reduction method, yielding AgNPs–CTT, which was further chemically conjugated to octreotide (OCT) to form AgNPs–OCT through an amide linkage. The AgNPs–OCT formulation was coated using alginate to yield a carrier, AgNPs–OCT–Alg, feasible for drug delivery through nebulization. AgNPs were uniform in size with an acceptable range of zeta potential. Furthermore, the concentrations of AgNP formulations were found safe for the model cell lines used, and cell proliferation was significantly reduced in a dose-dependent manner (p < 0.05). In the healthy lung tissues, AgNPs–OCT–Alg accumulated at a concentration of 0.416 ± 5.7 mg/kgtissue, as determined via inductively coupled plasma optical emission spectrometry. This study established the accumulation of AgNPs, specifically the AgNPs–OCT–Alg, in lung tissues, and substantiated the active, specific, and selective targeting of SSTRs at pulmonary sites. The anticancer efficacy of the formulations was in vitro tested and confirmed in the MCF-7 cell lines. Owing to the delivery suitability and cytotoxic effects of the AgNPs–OCT–Alg formulation, it is a potential drug delivery formulation for lung cancer therapy in the future.

Regulation of Asbestos in Soil, Waste and Recycled Materials in Western Australia
Authors: Otness Pierina
Published: December 2021

Regulation and management of asbestos as a contaminant is an increasing concern for countries such as Australia. The intent of regulation is to ensure asbestos contamination is identified early and managed properly and to ensure that any remaining site contamination is recorded and managed in perpetuity to prevent uncontrolled exposure. There is a need for regulation and control of asbestos to consider both worker and community expectations and concerns with regard to finding asbestos contamination either now or in the future. The issues considered to be important in Australia for the regulation of asbestos in soil, waste, and recycled materials include the legal interpretation of existing legislation related to asbestos to ensure that it meets the regulator's intent. The inclusion of regulatory criteria or cutoff concentrations for regulatory control of asbestos in soil, waste, and recycled materials needs careful consideration. The Western Australia Department of Health is revising its Guidelines for the Assessment, Remediation and Management of Asbestos-Contaminated Sites in Western Australia to better regulate asbestos in soil and this has provided an opportunity to review manner and extent of regulatory control of asbestos and other mineral fibers and the need to consider certain principles, such as precautionary principle and the principles of proportionality, sustainability, and intergenerational equity.
Background Levels of Asbestos Detected throughout the City of Houston, Fourth-Largest City in the United States

Published: December 2021

Outdoor concentrations of asbestos in urban environments have been suggested as a potential cause of some asbestos-related diseases. This assertion is contingent upon asbestos being at detectable levels in urban environments. Unfortunately, the studies cited are outdated and utilize methodologies that fail to detect both short and thin fibers. Previous studies on urban ambient asbestos concentrations were completed in 1985 utilizing only phase contrast microscopy (PCM). The last published paper to evaluate urban ambient asbestos concentration utilizing analytical transmission electron microscopy (ATEM) was conducted in 1977. We are not aware of any published or peer reviewed study since that has sampled or analyzed ambient air in urban environments utilizing either PCM or ATEM. In this study, Eurofins J3 Resources, Inc. (EJ3) conducted an ambient air study by collecting 29 samples over 10 days from two different locations within the Greater Houston area in Texas. Houston, by population the fourth-largest city in the United states and the third-largest city by physical size, was chosen for this investigation in part because of its diverse settings from industrial (refineries, petrochemical plants, and ports) to high population density areas (downtown, shopping malls) to miles of freeways (which includes 575.5 miles of freeways) to quiet suburban neighborhoods. The collected samples were analyzed by PCM using NIOSH 7400 and by ATEM using ISO 10312 counting methods. During this investigation, no fibers or asbestos structures were identified by either PCM or ATEM, respectively. Background levels of asbestos, if present, are presumed to be below the applied method detection limits of 0.001 f/cm3 for PCM and 0.0001 f/cm3 for ATEM.

Published: December 2021

The study presents an assessment of the impact of structural factors on the financial stability of pension systems in European countries. The purpose of the study is to determine the internal structural factors that have the most significant impact on the financial stability of pension systems in European countries. A review of the scientific literature dealing with the study of the financial stability of European pension systems is carried out. The correlation between the concepts of "financial stability" and "financial resiliency" is determined, the structural factors of pension models are identified and their grouping is carried out. The ranking of European pension systems by the level of their stability (including periods of financial crises) is carried out. The reasons for the decline in the stability and resiliency of European pension systems at this stage of development are identified. The study shows the internal structural factors that have a positive or negative impact on the degree of financial stability and financial resiliency of European pension systems. The conclusions obtained in the study can be used in the formation of the state pension policy of European countries and the choice of directions for reforming pension systems
Learning on Religion in the Modern European Education: new approaches to the teaching
Authors:   Leningrad (Pushkin) State University, Miroshnikova Elena
Published: December 2021

The article analyzes significant changes of the sociocultural and religious landscape in the modern post-secular Europe, which have led to the need of new approaches to religious education. According to the European Educational School’s Principles, religious education (confessional and non-confessional models) is an integral part of the curriculum. Religion is an ordinary, but a non-progression subject. In some European countries religious education is under a threat. There is an ambivalent process of the quest for multi-layered religious identities within the public schools of post-secular European countries. The author states that the traditional confessional model as a variant of catechesis is evolving to the system of multi-confessional religious education, Alternatives (Ethics, Ethics and Values, philosophy, citizenship), parallel mandatory courses about religion under Toledo principles (2007). Confessional religious education is teaching the religion in question. The author notes the growing role of the model of interreligious education IRE as a non-confessional academic Study of Religion for all students in the classroom. The most important international projects REDCo (Religion in Education. A Contribution to Dialogue or a Factor of Conflict in Transforming Societies of European Countries) and ENRECA network (The European Network for Religious Education through Contextual Approaches) show clear signs of the characteristics of interreligious education: teaching about is combined with teaching from the insider’s perspectives. Especially interesting are different options of the cooperative religious education and the model of intercultural religious education ICRE with a worldview as a key notion. The main goal of the IRE is working towards a public, rational discourse of religion against the privatization of religion, against displacing religion from educational institutions. The conclusion is made that the multi– disciplinary approach, based on Culture and Religious Studies, is capable to increase the quality of learning on religions.

Authors: Musa Suaad , Sedeq Medya
Published: December 2021

Background and objective: Ocular posterior segment lesions can affect individuals of both sexes at all ages. Such lesions can lead to serious manifestations such as retinal detachment and retinal hemorrhage, leading to permanent loss of eyesight. This study aimed to determine the association between age and gender and changes in ocular posterior segment based on ultrasonography findings. Methods: This prospective cross-sectional study included 50 patients with blurry vision who had been referred from ophthalmology outpatient clinics to the radiology department of Rizgary Teaching Hospital in Erbil, Kurdistan region in Iraq. Required data were collected using a researcher-designed questionnaire, and the patients were examined using a high resolution 7.5-10 MHz linear array ultrasound transducer. Results: The most frequent complications associated with ocular posterior segment pathologies were old vitreous hemorrhage (72%), posterior vitreous detachment (36%), and retinal detachment (34%). Diabetes and hypertension were the most frequent diseases associated with ocular posterior segment pathology. A significant association was seen between the patients' age with old vitreous hemorrhage (P = 0.003). A significant association was seen between the patients’ medical conditions with old vitreous hemorrhage and retinal detachment. There was no significant correlation between the patients’ gender and the studied ocular posterior segment pathologies. Conclusion: Age has a strong correlation with old vitreous hemorrhage, chronic medical conditions such as diabetes, and hypertension correlated with old vitreous hemorrhage and retinal detachment. Keywords: Ocular ultrasonography; Posterior segment pathology; Blurred vision; Age; Gender.
Impact of iron deficiency anemia on HbA1c level in non-diabetic children
Authors: Qader Mohammed , Rabaty Abbas
Published: December 2021

Background and objective: HbA1c has been endorsed by the American Diabetes Association and World Health Organization to diagnose and monitor diabetes mellitus. Its value is directly proportional to the blood glucose level. However, besides the blood glucose level, other factors like iron deficiency anemia can affect HbA1c level. We conducted this study to reveal the impact of iron deficiency anemia on HbA1c level and to assess whether HbA1c result changes after the correction of iron deficiency anemia. Methods: Twenty five non-diabetic children who were confirmed to have iron deficiency anemia were enrolled. HbA1c, hemoglobin, serum iron, and ferritin were measured and compared at baseline and post-correction of iron deficiency anemia with a three-month age-appropriate dose of iron therapy. The baseline results were compared with 25 age- and sex-matched normal controls. Results: Children with iron deficiency anemia had significantly higher HbA1c level (6.144±0.6312, P <0.001) than the control group (5.032±0.5558, P <0.001). After three months of treatment of iron deficiency anemia, HbA1c significantly dropped (from 6.144±0.6312, P <0.001 to 5.604±0.51, P <0.001). Conclusion: This study concluded that HbA1c is inversely proportional to iron deficiency anemia in non-diabetic children, and treatment of iron deficiency anemia led to a drop in HbA1c level. Due to this false elevation of HbA1c by iron deficiency anemia, iron deficiency anemia should be considered and excluded before making the diagnosis or deciding on any therapeutic change in diabetic children. Keywords: Iron deficiency anemia; HbA1c; Non-diabetic children.

Authors: Hamasalih Khanda , Nitham Walid
Published: December 2021

Background and objective: Community pharmacists play an important role in the best use of drugs and in improving patient outcomes. Evidence demonstrates that pharmacists' counseling improves the quality of life, clinical outcomes, and drug and disease knowledge and reduces the utilization of health services. This study aimed to investigate the nature and extent of counseling practices of community pharmacists in community pharmacies in Sulaimani region of Kurdistan, Iraq. Methods: A cross-sectional survey was conducted in community pharmacies in Sulaimani city, in a one-month duration from November to December 2020. The sample size was 100 community pharmacies, which were selected randomly. The data were stored and analyzed using Excel 2016 and expressed as frequencies and percentages. Results: According to the completed questionnaires, about 78.8% of pharmacists would do counseling spontaneously each time they dispense any drug. Only 61% of the pharmacists would ask the patients if they understood what was said during their communication to assess the understanding of advice given to their patients. The most common barrier observed during patient counseling was the patient's lack of time. Conclusion: This study indicates that community pharmacists counsel the patients in an appropriate way. They provide information orally and in written form. However, further research is needed to evaluate the quality of patient counseling by using different methods like pseudo-patient methodology to gain real counseling data. Keywords: Counselling; Community pharmacist; Community pharmacy; Counselling barriers.

Authors: Uddin Md. , Rahman A.Z.M. , Mondol Sumon
Published: December 2021

The energy crisis and environmental impact are the major concern mf the present world. Three-wheeler auto-rickshaw becoming an important passenger transport vehicle in a developing country which are indirectly powered by the grid electricity through the batteries. Such vehicle consumes significant grid energy during charging which increases the load in the national grid and put extra stress on the electrification in line with the environmental impact. This paper investigated the existing facilities for charging auto-rickshaw in Bangladesh and designed a proposed solar charging model as a replacement based on the existing model. Then the energy and environmental benefit were estimated to reflect the significance of the proposed model and contribution in the context of the global energy crisis and environmental impact. The investigation found that the daily energy consumption is 290 kWh for a charging station capacity of 30 auto-rickshaws which is significant. The proposed solar model is designed to meet this demand offset. The environmental analysis showed that the proposed model can offset CO2, CH4, and NOx emissions by 54 tCO2eq, 40 kgCO2eq, and 60 kgCO2eq per year respectively of which the contribution of CO2­ is significant. Further research could be focused on the economic and financial analysis in-depth to promote the proposed model.
The Modernization of a Historic City as the Construction of a Soviet Utopia: Case of Vilnius
Authors: Rožėnė Rugilė
Published: December 2021

The article looks at urban planning and construction processes in Vilnius during the Soviet era from a point of view that has not been widely explored in the existing historiography. The approach is based on analysing relations between the existing city and the city-in-construction within the context of Soviet urban modernisation. Interpreting the communist city as a utopia, the analysis looks at its role in shaping negative attitudes towards the historic city as well as what tangible forms this utopia assumes in the process of being realised. The article argues that this process, purportedly a rational way towards the utopia and characterised by a fragmentary implementation of development projects, is one of the main factors behind the disintegration of the urban space in the Soviet era.
On topology of manifolds admitting gradient-like calscades with surface dynamics and on growth of the number of non-compact heteroclinic curves
Authors: Grines Vyacheslav Z. , Gurevich Elena Ya. , Yakovlev Evgenii Iv.
Published: December 2021

We consider a class GSD(M3) of gradient-like diffeomorphisms with surface dynamics given on closed oriented manifold M3 of dimension three. Earlier it was proved that manifolds admitting such diffeomorphisms are mapping tori under closed orientable surface of genus g, and the number of non-compact heteroclinic curves of such diffeomorphisms is not less than 12g. In this paper, we determine a class of diffeomorphisms GSDR(M3)⊂GSD(M3) that have the minimum number of heteroclinic curves for a given number of periodic points, and prove that the supporting manifold of such diffeomorphisms is a Seifert manifold. The separatrices of periodic points of diffeomorphisms from the class GSDR(M3) have regular asymptotic behavior, in particular, their closures are locally flat. We provide sufficient conditions (independent on dynamics) for mapping torus to be Seifert. At the same time, the paper establishes that for any fixed g geq1, fixed number of periodic points, and any integer n≥12g, there exists a manifold M3 and a diffeomorphism f∈GSD(M3) having exactly n non-compact heteroclinic curves.
Numerical analysis of heating by a current pulse of a niobium nitride membrane in its longitudinal section
Authors: Kuzmichev Nikolay D. , Danilova Ekaterina V. , Vasyutin Mikhael A.
Published: December 2021

A numerical calculation of the evolution of the temperature distribution in the longitudinal section of a niobium nitride membrane when it is heated by an electric current pulse is performed. Mathematical modeling was carried out on the basis of a two-dimensional initial-boundary value problem for an inhomogeneous heat equation. In the initial boundary value problem, it was taken into account that current and potential contacts to the membrane serve simultaneously as contacts for heat removal. The case was considered for the third from the left and the first from the right initial-boundary value problem. Analysis of the numerical solution showed that effective heat removal from the membrane can be provided by current-carrying and potential clamping contacts made, for example, of beryllium bronze. This makes it possible to study the current-voltage characteristics of superconducting membranes near the critical temperature of the transition to the superconducting state by currents close to the critical density without significant heating.
Investigation of dynamic processes in pressure measurement systems for gas-liquid media
Authors: Tamarova Yuliya A. , Velmisov Petr A. , Aleksanin Nikolai D. , Nurullin Nail I.
Published: December 2021

Initial-boundary value problems for systems of differential equations are considered, which are mathematical models of the mechanical system "pipeline - pressure sensor". In such a system, to mitigate the effects of vibration accelerations and high temperatures, the sensor is located at a certain distance from the engine and is connected to it via a pipeline. The "pipeline - pressure sensor" system is designed to measure pressure in gas-liquid media, for example, to control the pressure of the working medium in the combustion chambers of engines. On the basis of the proposed models, the joint dynamics of the sensitive element of the pressure sensor and the working medium in the pipeline is studied. To describe the motion of the working medium, linear models of fluid and gas mechanics are used, to describe the dynamics of a sensitive element, linear models of the mechanics of a deformable solid are applied. Analytical and numerical methods for solving initial-boundary value problems under study are presented. The numerical study of the initial-boundary value problem was carried out on the basis of the Galerkin method. In analytical study using the introduction of averaged characteristics, the solution of the original two-dimensional problem is reduced to the study of a one-dimensional model, whose further study made it possible to reduce the solution of the problem to the study of a differential equation with a deviating argument. Also, a numerical experiment is carried out and an example of calculating the deflection of the sensor’s moving element is presented.

A tanulmány a közép-szlovákiai Zólyomban (Zvolen) Pusztavár-Alsóvár lakótoronyának kutatásából származó leletek elemzésével foglalkozik. Az Alsóváron található lakótorony építése és használata a 13. századra, fokozatos pusztulása a 14. század elejére tehető. A vár a híres középkori Zólyomi erdő területén található. Az elhagyott várból származó csontleletek 3633 darabot tartalmaztak, amelyek súlya körülbelül 19,3 kg. A sorozatban a háziállatok domináltak (szarvasmarha, sertés, juh/kecske, kutya, macska stb.), és kevesebb a vadászott állat (őz, gímszarvas, nyúl, mókus stb.). Szerepelnek köztük társállatfajok, békák és a malakofauna maradványai is. A madárcsont leletek között nemcsak a háziasított fajok (házi tyúk, lúd, kacsa, házi galamb), hanem vadon élők is (fácán, fürj, szajkó, sólyom stb.) előkerültek. A régészeti maradványok túlnyomórészt konyhai hulladékot képeztek, de lehetővé teszik a vár környéke természeti környezetének feltárását is. Végül az elemzés betekintést nyújtott a lakosok étkezési szokásaiba is, és tanúskodhat a vizsgált vár gazdasági körülményeiről.

Felsőzsolca-Nagyszilváson az 1999–2000 között folyó feltárások során a 27. sírból előkerült egy hosszú ideig meghatározhatatlan 14–15. századi, baltikumi származásúnak vélt pénz. A sírban más melléklet nem volt, így keltezése is bizonytalan lábakon állt. Közel húsz év elteltével derült fény a pénz származási helyére az első ilyen veret ugyanis csak 2013-ban került elő Lengyelországban, Piotrówka erődjében. Napjainkig mindössze hat veretet ismerünk a típusból.

A szimbolikus temetkezések az európai neolitikum és rézkor jellegzetes objektumai. Annak ellenére, hogy a kutatás hagyományosan úgy értelmezi őket, mint azon emberek jelképes sírjait, akik az otthonuktól távol lelték halálukat, más értelemzési módok is lehetségesek. Célszerűbb talán úgy tekinteni rájuk, mint a temetkezési szokásrendszerekben létező, komplex üzeneteket hordozó jelenségekre. Összetett szerepük jobb megértésének céljából a cikk 139 szimbolikus temetkezést elemez részletesen.

The use of analytical solutions for Frick`s diffusion equation to define the main sorption constants leading to the necessity to solve the united problem is shown. To be more exact this is the application assessment of analytical solutions for more often used experimental results and the determination of the representative sample dimensions in the experiments which are need to construct the sorption/desorption curves. By numerical experiments it is established that the most exact values of masstransfer constants are determined for small and middle values of diffuser absorption temporary process with the help of analytical solutions. Because of the difference in real sample dimensions and structural models used for analytical solutions which as a rule are presented in the form of semi-infinite plates it is necessary to minimize the influence of side surfaces in real samples on the accuracy of masstransfer parameters determination. The numerical-analytic study according to the geometry of polymeric samples from the point of view their representation to define diffusion, solubility and swelling coefficients is conducted. Herewith it is brought out that to obtain the values of masstransfer constants to an accuracy of not more 3 %, the sample geometric features must be chosen with relative dimensions L/h >10 (L – width, h – height of sample, accordingly) – the conditions of plane omnidirectional absorption of the diffuser into the right-angle-formed plates. To obtain the diffusion, solubility and swelling coefficients to an accuracy of not more 3 % the cylinder samples with relative dimensions D/h >15 (D – diameter, h – height, accordingly) should be preferably used. The algorithm of masstransfer constants determination when jointly use the sorption curves and the numerical method of diffusion analysis – finite element method is proposed. Herewith the advantages of such approach removing the sample size and shape limits are shown in comparison with the analytical methods of diffusion analysis.

Numerical investigation of influence of a slot-type casing treatment on acoustic and aerodynamic characteristics of the fan of ultra-high bypass ratio turbofan is presented. The investigation was performed using NUMECA FINE/Turbo solver. NLH harmonic method was used to simulate the effect of casing treatment on unsteady flow field in the turbomachine. Two operational conditions were investigated – “sideline” and “approach”. The attention for the first operational condition was paid for aerodynamic characteristics. Significant influence of casing treatment on them was found especially near the surge line. At the “approach” operational conditions the attention was paid for the proper calculation of tone noise. It was shown that the installation of casing treatment leads to decrease of power of tone noise radiated through the inlet. However the power of the tone noise, radiated through the nozzle, and also the overall power of tone noise increase.

The article is devoted to the consideration of the main problems of mathematical modeling and the most rational presentation of the results of numerical research of hydro-mechanical regulators of aircraft at the stage of practical design. Traditionally, the analysis and synthesis of hydraulic automation devices of aviation systems are performed on the basis of linear frequency methods of the theory of automatic control, which allow us to obtain approximate characteristics: accuracy, stability, controllability. The main task in this case is to develop such assumptions and solutions that would allow solving the problem in an analytical form. However, the number of nonlinear problems completed by analytical methods is negligible. In such a situation, computer modeling becomes an alternative. Mechanization and partial automation of the computational experiment led to qualitative changes in the simulation results and allowed us to obtain generalized diagrams of the dynamic state of the studied systems. Using a specific example, the issues of algorithmic modeling, analysis and numerical study of the dynamic characteristics of the automatic control system of aircraft on transient modes are considered. The paper clearly demonstrates how the application of the generalized variables method helps to present the results of numerical experiments in a rational form and to determine the influence of parametric complexes on the main characteristics and to construct generalized dynamic characteristics according to the main quality criteria

The literature overview on the issue of breastfeeding in neonatal departments, including neonatal intensive care units, is presented. The importance of breastfeeding for newborns with perinatal pathology is justified, as breast milk is vital for these children due to its unique sanogenetic properties. Data on special preventive and therapeutic role of breastfeeding for premature infants is presented. Reasons that complicate the use of breast milk in neonatal hospitals were analyzed (including those related to insufficient bacteriological and virological safety of native breast milk due to methodological errors during its collection and usage). Particular attention was paid to ensuring the breastfeeding safety during new coronavirus infection pandemic. This difficult period has demonstrated and confirmed the expediency of combining two breastfeeding approaches in perinatal centers: use of maternal milk and use of donor breast milk. Another section of review is devoted to modern breast milk processing technologies. Use of electric clinical breast pumps is crucial for promoting and supporting breastfeeding in the perinatal center.
