Mathematical Modelling of Dust Transfer from the Tailings in the Alagir Gorge of the RNO-Alania
Authors: Kamenetsky E. S. , Radionoff A. A. , Timchenko V. Yu. , Panaetova O. S.
Published: January 2024

Introduction. Mathematical modelling of the aerodynamics of mountain gorges is an actual means of studying possible man-made emissions in various meteorological conditions that increase the transfer of pollutants in the direction of densely populated areas. Aerodynamics and climatic conditions are unique for various mountain gorges. This requires a separate study for each speciﬁc case. The paper studies the distribution of dust aerosol from the Unal tailings dump, located near the village of Verkhny Unal (Alagir Gorge, RNO-Alania, RF), with south and south-easterly winds. With these wind directions, the dust of the tailings dump is carried by air currents in the north direction, towards Alagir. The aim of the study is to obtain a forecast for the surface concentration of dust with an increased content of lead, zinc and other elements near densely populated areas of the ﬂat part of RNO-Alania.

Materials and Methods. The model takes into account the terrain, surface wind roses and dust deposition processes. The calculations were carried out for the case of neutral stratiﬁcation and without taking into account the inﬂuence of seasonal factors using a mathematical model previously published by the authors.

Results. The model prediction of the dust concentration distribution obtained from calculations is shown. The frequencies and amplitudes of oscillations of unsteady jet streams in the cross section of the Alagir gorge are analyzed. Based on the data of satellite sensing of the Earth’s atmosphere, the frequency of winds leading to the transfer of dust in the direction of densely populated areas is estimated.

Discussion and Conclusion. The Unal tailings dump is a source of pollutants and over many years of its existence, soil contamination can be signiﬁcant. Field studies of the soil in the Alagir area and, possibly, measures for its reclamation are necessary.

A robotic reporter still lacks creativity, but it can already replace human journalists in several areas
Authors:   Charles University, Czechia, Macková Veronika , Mařík Radek ,   Czech Technical University, Czechia
Published: January 2024

Automated journalism is experiencing rapid advancements, prompting concerns among certain journalists who fear potential job displacement by robotic reporters. Conversely, there is a cohort of journalists embracing this progress, viewing the involvement of robotic reporters as a time-efficient measure and an avenue to engage in more creative forms of journalism. This article aims to explore topics in Czech Republic news that lend themselves to automation based on perplexity. Currently, the robotic reporter can generate articles in few domains (e.g., stock market news, fuel prices news, and traffic accident reports), while further exploration is underway for other areas. However, generating e.g. cultural news through automation remains challenging due to its less recurrent nature, as evidenced by perplexity measurements reflecting text complexity. Perplexity method can be used to determine which journalistic area is suitable for automated text. In this article, we focus on the Czech environment and the possibilities of automation and the reaction of selected Czech journalists who encounter automated texts in newsrooms. While automated journalism demonstrates superiority over human journalists in certain aspects, it still falls short in terms of creativity, an aspect where artificial intelligence remains unable to replace humans. Nevertheless, the robotic reporter can serve as an invaluable assistant to editors and reporters in their work. Consequently, the newsroom landscape is evolving, accommodating the integration of automated content editors.

Published: January 2024

ABSTRAKPada keluarga campuran, terdapat perubahan yang membutuhkan penyesuaian dalam aspek-aspek keluarga. Proses perwujudan keluarga dalam keluarga campuran memiliki perbedaan dengan keluarga pada pernikahan sebelumnya. Studi ini bertujuan untuk mengkaji adaptasi yang terjadi pada keluarga campuran dan negosiasi yang dilakukan anggota keluarga campuran dalam berbagai kegiatan dan interaksi pada keluarga campuran. Studi ini menggunakan metode penelitian kualitatif dengan konsep family practice dari David Morgan. Informan dalam penelitian ini sebanyak sembilan orang. Studi ini menemukan variasi proses adaptasi pada keluarga campuran yaitu proses adaptasi secara holistik, natural, dan secara terpaksa. Pada negosiasi terkait dengan kegiatan komunal keluarga campuran dilakukan secara eksplisit dan implisit. Proses perwujudan keluarga pada keluarga campuran dapat dilihat melalui proses adaptasi dan negosiasinya. Kedua hal ini yang kemudian membedakan dengan keluarga pada pernikahan pertama. Dalam aspek-aspek tertentu, keluarga campuran di Indonesia masih dipengaruhi oleh hal-hal yang bersifat kultural seperti dalam hal mediasi ketika terjadi konflik hingga rasa sungkan dengan anggota keluarga baru. Kata Kunci: Praktik Keluarga, Keluarga Campuran, Adaptasi, Negosiasi, Keluarga Tiri  ABSTRACTChanges in blended families necessitate adaptations to several aspects of the family. As a result, the process of building a family in a blended family differs from that of a family formed through a first marriage. This research stems from a desire to comprehend the embodiment of the family in a blended family through family communal activities such as family rituals and routines. This study examines the adaptations that occur in blended families and the negotiations that blended family members engage in addressing various activities and interactions. This study employed a qualitative method using the concept of family practice by David Morgan. Nine informants were involved in this study. This study revealed three types of adaption processes in blended families: holistically, naturally, and forcibly. Negotiations around communal activities in blended families take place both explicitly and implicitly. In a blended family, the process of an embodiment of the family can be seen through adaptation and negotiation processes. These two factors distinguish a blended family from a family formed through a first marriage. In certain ways, blended families in Indonesia continue to be influenced by cultural factors, such as mediation when there is a problem or feeling reluctant with new family members. According to the findings of this study, cultural traits are able to unite two families. Keywords: Family Practice; Blended Family; Adaptation; Negotiation; Stepfamily

ABSTRAK  Sanitasi lingkungan merupakan faktor penting untuk mewujudkan kesehatan masyarakat. Namun masalah sosial terkait sanitasi lingkungan banyak terjadi di lingkungan pemukiman perkotaan dengan kondisi padat penduduk dan kumuh, sehingga berpengaruh terhadap kesehatan masyarakat. Tujuan dari artikel ini mendeskrpsikan dan menganalisis kondisi sanitasi lingkungan di wilayah pemukiman perkotaan khususnya di wilayah ”Gang K” yang berada di wilayah Kebon Jeruk Kota Bandung. Hasil penelitian dianalisis dengan menggunakan teori Kesehatan Masyarakat H.L Blum. Metode penelitian yang digunakan adalah kualitatif, dengan teknik pengumpulan data terdiri dari wawancara mendalam, observasi dan dokumentasi. Teknik pengolahan data meliputi tahap reduksi data, penyajian data, penarikan kesimpulan dan verifikasi. Hasil penelitian menunjukkan bahwa kondisi pemukiman perkotaan yang berada di wilayah ”Gang K” menunjukkan kondisi permukiman kumuh, ditandai dengan keterbatasan infrastruktur dasar, sehingga kondisi sanitasi lingkungan di wilayah tersebut kurang baik dan menimbulkan berbagai sumber penyakit. Temuan ini memperkuat Teori Blum bahwa walaupun terdapat empat faktor yang mempengaruhi derajat kesehatan masyarakat  yaitu perilaku, lingkungan, pelayanan kesehatan, dan keturunan (hereditas), namun faktor lingkungan  khususnya sanitasi lingkungan menjadi faktor penentu dalam meningkatkan derajat kesehatan masyarakat. Kata Kunci: Masyarakat Perkotaan, Masalah Sosial, Pemukiman, Sanitasi LingkunganABSTRACT Environmental sanitation is an important factor in realizing public health. However, many social problems related to environmental sanitation occur in urban residential environments with densely populated and slum conditions, thus affecting public health. The purpose of this article is to describe and analyze environmental sanitation conditions in urban residential areas, especially in the “Gang K” area located in the Kebon Jeruk Village area of Bandung City. The results of the study were analyzed using H.L. Blum's Public Health theory. The research method used is qualitative, with data collection techniques consisting of in-depth interviews, observation, and documentation. Data processing techniques include the stages of data reduction, data presentation, conclusion drawing, and verification. The results showed that the condition of urban settlements in the alley "K" area showed the condition of slums, characterized by limited basic infrastructure so that environmental sanitation conditions in the area were not good and caused various sources of disease. This finding strengthens Blum's theory that although four factors affect the degree of public health, namely behavior, environment, health services, and heredity, environmental factors, especially maintaining environmental sanitation, are determining factors in improving the degree of public health. Keywords: Urban Communities, Social Problems, Settlements, Environmental Sanitation

Authors: Kalenik Marek , Chalecki Marek , Wichowski Piotr , Kiczko Adam , Chmielowski Krzysztof , Świętochowska Martyna , Gwoździej-Mazur Joanna
Published: January 2024

The paper presents the results of studies on local resistance coefficients (ζ). The study used pipe aerators with filling made according to the Polish patent PL235924. The hydraulic investigations were performed in real working conditions of a water treatment plant in a testing rig built in the Scientific and Research Water Station of the Warsaw University of Life Sciences (SGGW). The investigation encompassed two plastic pipe aerators of an internal diameter 101.6 and 147.6 mm with steel Białecki rings of 12 and 25 mm in diameter. Measurements of pressure difference (Δp) in the investigated aerators were performed at volumetric water flows ( Q) selected from the range 2–20 m 3∙h –1 with the interval 2 m 3∙s –1. The values of ζ were determined according to the PN-EN 1267:2012 standard. The investigation showed that the ζ depends both on an internal diameter of the plastic pipe aerator and the diameter of Białecki steel rings. The values of ζ increase with a decrease of the internal diameter of the pipe aerator and a decrease of the ring diameter.
Detection of multi-nutrients deficiency in cereal plants by the use of chlorophyll fluorescence
Authors: Jaszczuk Zuzanna Malwina , Bąba Wojciech
Published: January 2024

Nutrient deficiency (ND) stands as a prominent environmental factor that significantly impacts global plant growth and productivity. While numerous methods have been employed for detecting nutrient deficiencies in plants, many of them are invasive, time-consuming, and costly. In contrast, chlorophyll fluorescence (ChlF) signals have emerged as a non-destructive tool for the identification of specific nutrient deficiencies, such as nitrogen (N), phosphorus (P), and potassium (K), across various plant species. In this pioneering study, ChlF measurements were employed for the first time to detect a combination of nutrient deficiencies, including deficiencies in nitrogen and phosphorus (–NP), nitrogen and potassium (–NK), potassium and phosphorus (–KP), and a complete NPK deficiency (–NPK). The experiment was conducted using wheat (Triticum aestivum) and maize ( Zea mays) plants, which were grown under controlled laboratory conditions. An optimal hydroponic system was established to facilitate eight experimental conditions, namely: control, –N, –P, –K, –NP, –NK, –KP, and –NPK. Measurements were systematically collected at two-day intervals over a span of 24 days. Our findings demonstrate that chlorophyll fluorescence signals can enable the differentiation of various nutrient deficiencies even prior to the onset of observable symptoms. Furthermore, the examination of chlorophyll fluorescence parameters enables us not only to identify a singular macronutrient deficiency but also to detect multiple macronutrient deficiencies concurrently in a plant.
Comparison of the effects of orbital decompression in Graves' ophthalmopathy
Authors: Skrzypczak Wojciech , Słowik Łukasz , Okła Maciej , Ślebioda Zuzanna , Osmola Krzysztof
Published: January 2024

Introduction

Graves' disease is an autoimmune disorder. One of the symptoms is an overgrowth of the soft tissues of the orbit. Orbital involvement can cause exophthalmos, diplopia, or vision loss. Treatment strategies include a surgical approach that limits the ailments mentioned above. Decompression can be achieved by reducing the amount of enlarged tissues (fat removal) or increasing the space for enlarged tissues (bone removal). Numerous authors discuss the advantages and disadvantages of various techniques in terms of reducing the exophthalmos, the number and persistence of complications, and the long-term prognosis.

Materials and Methods

A literature search of PubMed and the Poznan University of Medical Sciences Main Medical Library resources from 1993–2022 was performed. Thirty articles were reviewed with attention to the surgical treatment of Graves' ophthalmopathy.

Results

The main surgical techniques include fat decompression and bone wall decompression. The results of exophthalmos fat removal are characterized by a significant decrease in proptosis (5.45mm) with a small percentage of newly formed diplopia (9%). Bone reduction in the lateral wall of the orbit shows similar effects: reducing exophthalmos (4.33mm) and the newly formed diplopia, as with fat removal (3.7%). Bone reduction in the medial- lateral wall, medial- inferior- lateral wall, and medial–inferior wall shows a decrease in proptosis ( 4.9 mm, 4.6 mm, 3.77 mm) and a higher percentage of new-onset diplopia (18%, 15%, 28%).

Conclusion

The smallest amount of newly formed diplopia at the highest proptosis reduction occurs with the self-removal of fat or resection of the lateral orbital wall.

The Fatty Acid Profile, and the Content of Vitamin A, Vitamin E and Cholesterol in Beef (M. longissimus lumborum) Stored Under Different Modified Atmospheres
Authors: Śmiecińska Katarzyna , Kubiak Dorota , Figger Karolina
Published: January 2024

The aim of this study was to analyze the fatty acid profile of intramuscular fat and the content of vitamin A, vitamin E and cholesterol in samples of the longissimus lumborum (LL) beef muscles and stored for 7, 14 and 21 days under modified atmospheres (MA): vacuum, 80% O2 + 20% CO2, 60% O2 + 30% CO2 + 10% N2, 40% CO2 + 60% N2, 30% CO2 + 70% Ar). The experimental factors, i.e., storage time (ST) and MA composition, had no significant effect on the proportions of individual saturated fatty acids (SFAs), but they significantly modified the proportions of individual unsaturated fatty acids (UFAs) and the fatty acid profile of intramuscular fat (IMF). The study demonstrated that in order to minimize the loss of total UFAs, samples of the LL muscle should be cold-stored in MA 40% CO2 + 60% N2 for up to 14 days; MA 30% CO2 + 70% Ar also effectively prevented the loss of total PUFAs and eicosapentaenoic acid (EPA). The losses of vitamins A and E were lowest when beef was packaged under oxygen-free MA, in particular MA 30% CO2 + 70% Ar. Prolonged storage (21 days) did not contribute to significant vitamin losses, but it induced a decrease in cholesterol concentration, which was lower in vacuum-packaged samples than in those packaged in MA containing 60% O2 and MA composed of 40% CO2 + 60% N2.
The Influence of Pre-Treatment, Preservation Method, and Storage Time on Carotenoid and Chlorophyll Profile in Nettle Juices and its Relation to Colour Changes
Authors: Bernaś Emilia , Fiutak Grzegorz
Published: January 2024

One of the most valuable health-promoting plants used in the production of functional, green drinks is nettle. Acidic environments, oxygen, high temperature, and enzymes can negatively affect the colour of green juices, which is an important aspect for consumers. Therefore, the study analyzed the effect of pre-treatment, preservation method (freeze-drying, freezing, sterilization), and storage on the profile of carotenoids and chlorophylls (HPLC) in nettles juices and its correlation with colour changes (CIELAB). All the examined parameters impacted the profile of both groups of compounds and their colour. The most significant unfavorable changes were observed after sterilization. Blanching positively affected the level of coloured compounds in canned juices, with a greater enhancement being observed after a longer pre-treatment time (90 s). After storage, in frozen and freeze-dried juices, and similarly in unpreserved juices, lutein, violaxanthin and chlorophyll a predominated. However, in sterilized juices, neoxanthin and violaxanthin were completely degraded, and β-carotene and chlorophyll b were found at a significant level. During the storage of canned and frozen products, chlorophyll a was degraded to a greater extent, while in lyophilizates chlorophyll b. The transformation of neoxanthin, violaxanthin and chlorophyll a in nettle juices was determined via analysis of a* colour parameter.
Influence of the Aging of Apple Wines with Oak Chips on the Quality and Sensory Parameters of the Wines
Authors: Tarko Tomasz , Krzysztof Natalia , Duda-Chodak Aleksandra
Published: January 2024

This study investigated the effect of the oak chips added at different dosages and stages of apple wine production on its oenological, antioxidant and sensory properties. In the study, medium-toasted or heavily-toasted oak chips (at a concentration of 3 or 6 g/L) and ethanol extracts prepared from them (at a dose of 1 or 2 mL/100 mL) were used. Basic oenological parameters (OIV), total polyphenol content (Folin-Ciocalteu method), antioxidant activity (ABTS assay), color (CIELAB) and organoleptic assessment of the wine were evaluated. Although the use of chips had no significant effect on the ethanol content and wine extract, it caused a significant change in volatile acidity. Furthermore, the antioxidant activity of the wines correlated closely with the concentration of polyphenolic compounds and these parameters were significantly higher after contact with medium-toasted chips. The apple wines had high values of lightness and yellow color, and the addition of chips did not significantly affect the color parameters (CIELAB). In the sensory assessment, the control wine (without chips) received the lowest scores, while significantly higher scores were given to the wine with the addition of 6 g/L of heavily-toasted chips, which was characterized by intense smoky, toasty, woody and vanilla notes.

Published: January 2024

This in silico study has been designed to validate ethnomedicinal properties of some Himalayan fermented ethnic beverages against varied high-altitude sicknesses. Traditional beverages like tongba, chhyang, nigar and finger-millet raksi (supplemented with ethnomedicines like khokim and chimphing) were considered in this study which were sampled from villages situated in Singalila Ridge of the Himalayas. Seven major metabolites such as ethyl alpha-D-glucopyranoside; meranzin; auraptene; cis-vaccenic acid; cyclo(pro-gly); cyclo(leu-pro); and 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one were investigated in silico to provide insights to their efficiency in alleviating major altitude illnesses (pulmonary edema and hypoxia); high-altitude respiratory infections; pain or inflammation; cardiovascular problems; gastrointestinal diseases and disorders; and high-altitude neurological diseases and disorders. Computational tools such as Molinspiration Chemoinformatics, SwissADME, Molsoft program and vNN-ADMET were employed to evaluate physicochemical properties, pharmacokinetics and ADMET parameters. Binding affinities were computed using Auto Dock Tools.

Wheat grain has health-promoting properties that are related to the content of phenolic acids in its composition, among which ferulic acid, syringic acid, p-coumaric acid and vanillic acid predominate acting as potent natural antioxidants. The study evaluated the phenolic acid (PA) content and grain yield of hybrid wheat genotypes (Hyland, Hywin) compared to the common variety (Patras), grown under an integrated system at two nitrogen rates of 60 (N60) and 120 (N120) kg·ha−1, under varying hydrothermal conditions during three growing seasons. The effects of genotype, cultivar and the interaction of cultivar and hydrothermal conditions on the phenolic acid profile, except for synapic acid, phydroxybenzoic acid and salicylic acid, and grain yield were confirmed in favour of the hybrid cultivars. The concentration of total phenolic acids (TPAs) and ferulic acid in the grain of the hybrid cultivar Hyland was higher and, in addition, greater yield stability of this cultivar under varying hydrothermal conditions was shown in the analysed years of the study. The grain of the common variety Patras was characterised by advanced content of p-hydroxybenzoic acid, and that of the hybrid variety Hywin by p-coumaric, caffeic and syringic acids. Higher TPAs content and lower grain yield of the varieties were observed in the 2018/2019 drought season. Higher nitrogen fertilisation (N120) compared to N60 significantly increased TPAs content and grain yield of Hyland and Hywin hybrid varieties. Fertilisation with N120 compared to N60 increased TPAs content by 4.2% and promoted higher concentrations of ferulic and syringic acids in the wheat cultivars tested.

Biological membranes are complex systems due to their composition and dynamics. Therefore, membrane mimetics are widely used to investigate lipid properties and interactions between molecules and membrane lipids. Using all-atom molecular dynamics simulations, within this study two systems composed of different membrane mimetics are compared: a 1-palmitoyl-2-oleoyl-3-glycero-phosphatidylcholine (POPC) bilayer or a dodecylphosphocholine (DPC) micelle and a nonapeptide (V94-T-K-Y-W-F-Y-R-L102). Previous 1H-NMR experiments have demonstrated that, in the presence of DPC micelles, this peptide folds as a stable amphipathic helix located in the polar head group region with the tryptophan residue pointing toward the inside of the micelle. The present comparison reveals a hydrophobic surface twice as large for the micelle as for the bilayer and a different arrangement of the acyl chains. The peptide secondary structure is not strongly affected by the membrane mimetics whereas the peptide is more deeply inserted in the bilayer than in the micelle. The contacts between the peptide and the DPC or POPC molecules are analysed and although the distances and lifetimes of these contacts are very different in the micelle and the bilayer, similar specific interactions were found that mainly involved the side chains of the residues R101 and L102.

Published: January 2024

Radioactive aerosols in the confined workplace are a major source of internal exposure hazards for workers. Cloud-type radioactive aerosol elimination system (CRAES) have great potential for radioactive aerosol capture due to their high adsorption capacity, lack of cartridges and less secondary contamination. A CRAES was designed and constructed, and a FeOOH/rGO composite was directly prepared by a hydro-thermal method to characterise and analyse its morphology, chemical structure and removal efficiency for simulated radioactive aerosols. The results show that the FeOOH/rGO composite works in synergy with the CRAES to effectively improve the removal efficiency of simulated radioactive aerosols. A 30-minute simulated radioactive aerosol removal rate of 94.52% was achieved when using the experimentally optimized composite inhibitor amount of 2 mg/L FeOOH/rGO with 0.2 g/L PVA as a surfactant. Therefore, the CRAES coupled with the composite inhibitor FeOOH/rGO has broad application potential for the synergistic treatment of radioactive aerosols.
Numerical simulation and improvement of combustor structure in 3D printed sand recycling system
Authors: Gao Xiao , Lei Mao , Xu Weiwei
Published: January 2024

In this paper, a new combustor with an output of 5 t/h is designed based on a computational particle fluid dynamics (CPFD) model. The flow field simulation is combined with the combustion simulation to analyze the internal two-phase flow, temperature field, and combustion products. The combustor structure was optimized. The simulation results show that the recovery efficiency of the waste sand and the energy utilization of the combustor can be improved under the original structure. The sand bed has a significant effect on flow field characteristics. The increase in particle temperature in the combustor increases the efficiency of waste sand recovery by increasing the height of the sand bed by 50 mm. The utilization rate of natural gas is increased and the economic efficiency is improved. The feasibility of the CPFD method can simulate the flow field characteristics inside the combustor very effectively.
Adsorption behaviour of polar solvent and water vapours on Sorbonorit B4 activated carbon
Authors: Downarowicz Dorota , Gabruś Elżbieta
Published: January 2024

In this work, the affinity of the heterogeneous Sorbonorit B4 (SB4) activated carbon toward methyl ethyl ketone (MEK), isopropyl alcohol (IPA), n-propyl alcohol (NPA) and isobutyl alcohol (IBA), and water vapours was examined. Adsorption equilibrium measurements demonstrate a higher adsorption capacity of water vapour than organic compounds at relative pressures above 0.4. The adsorption capacities of SB4 at the same vapor pressure followed the order: NPA> IPA> MEK> IBA. The Langmuir, Dubinin-Radushkevich, Dubinin-Astakhov, and Toth isotherm models were chosen to describe experimental results. Based on the multi-temperature isotherms, the values of the isosteric heat of adsorption were determined for various adsorbate loading. The results indicate a strong influence of VOC molecule structures and the surface heterogeneity of SB4 on the adsorption efficiency. For IPA-SB4 pair, the maximum temperature rise in a fixed-bed bed in the adsorption process and the energy requirement for regeneration were calculated and experimentally verified.

In the study, the influence of distillation time as well as distillation apparatus on the chemical composition and quality of lavender (Lavandula angustifolia Mill.) essential oil were investigated. Two different types of distillation apparatuses: Deryng (popular in Poland) and Clevenger-type (recommended by European Pharmacopoeia) were used for the isolation of the essential oil from dried lavender flowers (Lavandulae flos). Moreover, different distillation times (2, 3 and 4 hours) were also applied. The chemical composition of the isolated oils, determined by gas chromatography coupled with mass spectrometry (GC-MS), revealed the dominance of linalool (11.55–17.19%) and linalyl acetate (12.84–16.78%) in the all analyzed samples. Other important constituents were: caryophyllene oxide (5.66–7.35%), lavandulyl acetate (4.64–5.40%) and borneol (4.62–5.51%). On the basis of the obtained data it was proved that the distillation time and distillation apparatus affect the amounts of some constituents in the lavender oil.

Published: January 2024

Health care sector is one of the most important sectors that affect the economies of all countries. On the one hand, it affects the productivity of labor force, on the other hand, it affects the spending of the households and the allocation of income among the various aspects of spending. In addition, the case of Egypt is characterized by some peculiarity in terms of The large population and the existence of a development gap between the cities of the north and the cities of the south, and the volume of out of pocket expenditure on health care which exceeds its counterpart in most countries of the world. In addition, health care service providers in Egypt are represented in the public sector, the private sector and the cooperative or community sector, where the three sectors provide health care services with different quality and prices. Therefore, this study aimed to identify the determinants of health care expenditure in Egypt through an econometric model. The results showed that spending on health care in Egypt was affected by percapita GDP and population over 65 years old while the econometric model shows no significance for variables such as hospital beds and number of medical doctors.
