This paper reports a study into the possibility of using LED systems of ultraviolet radiation for air ionization and disinfection of air and indoor surfaces in the presence of people. It has been established that UV LED lamps with 120° opening angles have parameters under which radiation intensity does not exceed 30 J/m2 at distances of 2 meters. Based on experimental data, a methodology for designing the placement of lamps in the room was devised, which meets the requirements of the SBM-2015 standard and the European Directive 2006/25/EU. The use of LED emitters with a total intensity of up to 25 J/m2 increases the concentration of aero ions. The background concentrations were 140‒180 cm-3 (positive) and 160‒190 cm-3 (negative). The minimum permissible level is 500 cm-3. As a result of irradiation, the concentrations were 1100‒1460 cm-3 (positive) and 1260‒1470 cm-3 (negative). The influence of the recirculator-air purifier on the concentration of aero ions has not been established. The ionization process began immediately after turning on the irradiation systems in the entire volume of the premises (4‒5 meters from the source). The dynamic equilibrium of aero ion concentrations was established within 10‒15 minutes after the irradiation was switched on. The presence of a large number of people (up to 0.97 m2 per person) did not affect the concentration of aero ions. Under the combined effect of ultraviolet radiation and a recirculator-air purifier, the number of mold fungi colonies decreased by 20 times. Under the influence of only ultraviolet radiation – by 2.3 times. The decrease in the number of microbes under the combined effect was 1.6 times, and under the effect of only ultraviolet radiation – 2.8 times
Pollution and damage to land resources of Ukraine as a sign of criminal offenses against peace, human security and international law and order in the context of russian military aggression
Authors: Shulha Andrii 
Published: July 2023

The article deals with the issues related to the legal protection of land resources of Ukraine, which were significantly negatively affected during the military aggression and hostilities by the so-called rusian federation. The article identifies and analyzes the types of pollution and damage to land resources arising from military aggression and hostilities by the rusian federation as an aggressor country. Such pollution and damage to land resources is called military-technogenic pollution of land resources. It is stated, that the conduct of not only active but also passive hostilities causes irreparable damage to land resources. This is manifested in mechanical, physical, chemical, and biological contamination of the soil cover of lands of various categories. Also, for example, digging trenches, fortified areas, ammunition and personnel storage facilities, and caponiers for military equipment causes degradation of the soil cover. The consequences of these actions indicate the presence of signs of such a criminal offense as "Ecocide" – Article 441 of the Criminal Code of Ukraine.
It is concluded, that: 1) military-technogenic contamination of the soil cover causes direct soil contamination with hazardous substances of a military nature, as well as their degradation; 2) such consequences are socially dangerous for humans and the environment, given the system of interaction "soil-plant", "soil-plant-human" 3) in general, such contamination of the soil cover should be classified under Article 441 "Ecocide" of the Criminal Code of Ukraine without applying the provisions of Section VIII "Criminal Offenses Against the Environment"; 4) the establishment of the evidence base should be carried out by joint efforts of national and international law enforcement agencies; 5) compensation for the damage, caused by the pollution and damage to land resources, should be made by way of contribution and reparation from rusia as the aggressor state

Depression and Physical activity among cardiac patients undergone cardiac events: a correlational study
Authors: Dhillon Sawroop , Kaur Kang Harmeet 
Published: July 2023

Objective. To assess prevalence of depression and its relationship with physical activity among individuals who haveexperienced a cardiac event.
Methods. This descriptive study involved 196 cardiac patients receiving treatment at selected cardiac hospitals of Punjab (India). Subjects were chosen using purposive sampling technique. After getting informed written consents from the participants the data was collected using International Physical Activity Questionnaire (IPAQ) and Beck Depression Inventory-II (BDI-II).
Results. The results showed that majority (62.2%) of the cardiac patients had moderate clinical depression and 11.2% of patients had severe depression. 86.7% of the patients had low level of physical activity (<600 MET min/week). There was also a significant negative correlation between the depression and physical activity depicting the higher the physical activity, lower was the depression score and vice-versa (p<0.05). Moreover, study results revealed that physical activity was significantly associated with age and educational status; whereas, depression was not associated with selected demographic variables.
Conclusion. The current investigation has brought to light that a vast majority of individuals suffering from cardiac issues exhibited signs of moderate to severe depressive symptoms. Additionally, the findings indicate an inverse relationship between depression and physical activity. Consequently, it is crucial for nurses to concentrate on identifying early indicators of depression and physical inactivity so that individualized care plans can be developed to enhance the overall health of cardiac patients.

Published: July 2023

Cement production plays an important role in strengthening the infrastructure of growing countries such as Colombia. However, the production of this material has a high energy cost and contributes to the emission of large amounts of CO2. To address these environmental concerns, it is essential to explore alternative materials that can partially or completely replace traditional cement. Alkaline activated cement (AAC) has emerged as a promising candidate in this regard. Due to this, it is necessary to understand the process of alkaline activation and the variables that influence it. This research proposes a phenomenological-based semi-physical model, which predicts the performance of some variables that control alkaline activation: activator concentration (NaOH), heat flow, and degree of reaction. The model results show that with the increment of the activator concentration, the degree of reaction also increases. Furthermore, the model has an accurate response compared with the Freisleben-Hansen model. The integral square error criterion (ISE) was used in this comparison.
Fetal valproate syndrome (review and case report)
Authors: Melashenko Tatyana V. , Palchik Alexander B. 
Published: July 2023

Toxic damages in fetuses and newborns rank highly in perinatal pathology structure, though their true importance is not understood thoroughly. Among toxic encephalopathies of newborns the accent should be given to the conditions caused by administration of medicines by a pregnant woman. The use of medicines, especially neurotropic, during pregnancy is often forced. The widespread prevalence of epilepsy in women of reproductive age leads, in certain cases, to anticonvulsants administration during pregnancy. The dominance of valproic acid in epilepsy treatment in recent decades requires studying its teratogenic effect in newborns fetal valproate syndrome. The fetal valproate syndrome has casuistic nature and polymorphic phenomenology.
The clinical case study is presented of a newborn with fetal valproate syndrome (born to a mother who took valproic acid in dose 14 mg/kg per day or 750 mg per day while pregnant, due to Janz syndrome), confirmed by valproic acid presence in the blood of a newborn (47.36 mol/l), with the main clinical manifestation of incomplete cleft palate (hard and soft) without other typical disturbances.
Most anticonvulsants have a teratogenic effect, and may cause malformations and toxic encephalopathies in fetus and newborns. The similarity of clinical manifestations of intrauterine exposure to various anticonvulsants is associated with the presence of common metabolic links (epoxy and dihydrodiol derivatives of phenytoin, phenobarbital and carbamazepine). In spite of similarity of some teratogenic effect mechanisms, the anticonvulsants nature introduces specific clinical manifestations of these disorders.

Purpose: to study the relationship of various forms of accommodative asthenopia (AA) with the characteristics of the professional activity of patients with visually stressful work (VSW) with the phenomena of computer visual syndrome (CVS).Methods. There were 150 patients with VSW — professional users of personal computers (mean age 28.8 ± 1.4 years) with myopic refraction (mean value of spherical equivalent 2.8 ± 1.1 diopters) under observation. The patients were divided into three groups: “normal” (50 patients); asthenic form of accommodative asthenopia (AFAA, pathology, 50 patients); habitual excessive tension of accommodation (HETA), pathology, 50 patients). All patients underwent a comprehensive ophthalmological examination for 13 parameters. As a basic diagnostic method, a specially developed questionnaire aimed at assessing professional activity was used. Statistical analysis of the results of the study was performed on the basis of an assessment of the average values of the correlation coefficients (ACC) between the patient’s responses (in points) and the studied indicators of the visual system.Results. High ACC were determined on issues characterizing the amount of daily visual load. However, no differences were found between APAA and HETA. The occurrence of AFAA is more often associated with the input of information, HETA — with reading. Evaluation of issues related to the regularity of the use of optical correction revealed differences in ACC (p < 0.05) between the “normal” group and the “pathology” groups, while in the “normal” group, optical correction was used in most cases “often” or “constantly”, in the “pathology” groups — “sometimes”.Conclusion. The results of the correlation assessment of the relationship between various types of AA in patients with VSW with the characteristics of professional activity and the parameters of the visual analyzer indicate the leading role of the duration and nature (input, reading of information) of daily work at a personal computer. One of the leading risk factors for the development of AA is inadequate optical correction. At the same time, there were no significant differences between AFAA and PINA. The most informative parameters of the accommodative system of the eye are the volume of absolute and relative accommodation (by the subjective method), as well as the coefficients of microfluctuations and stability of accommodogram (by the objective accommodation method).

The neuro-ophthalmic symptoms and signs associated with COVID-19 infection are varied and span the course of the infection to the convalescent phase. In addition to the anterior segment of the eye, there is a possibility of damage to the posterior segment of the eyeball. The described cases are isolated and there are no results of treatment of patients who have undergone COVID-19.Purpose: To describe the outcome of treatment of bilateral optic nerve edema after COVID-19.Methods. A 59-year-old man with reduced visual functions in the post-surgical period was examined. A standard ophthalmological examination was performed. In addition, spectral optical coherence tomography (OCT) of the macular area of the retina and optic disc (OND) was performed using the RTVue XR Avanti apparatus (Optovue, USA). The patient underwent a laboratory study.Results. Bilateral papilledema was detected in a patient after COVID-19. According to OCT data, a thickening of the nerve fiber layer of the retina of both eyes was revealed, according to OCT angiography, a decrease in the density of the RPC. Conducted a course of conservative and physiotherapy treatment.Conclusion. The COVID-19 epidemic poses several challenges for the ophthalmological community: to determine algorithms for timely diagnosis and treatment, as well as to ensure the prevention of complications from the organ of vision in patients who have undergone COVID-19. It may make sense to screen for coronaviruses in patients with inflammatory diseases of the posterior segment of the eye of unknown etiology. The inclusion of spectral optical coherence tomography with the function of angiography in a comprehensive examination of patients is important for the early detection of microcirculatory and morphometric changes in the optic disc, macular and peripapillary retina. It is advisable to use physiotherapeutic methods of treatment in patients with visual impairment in the post-COVID period, which will reduce the long-term drug load and increase the effectiveness of treatment.

The Romance of Commerce:&nbsp;<em>Rob Roy</em>, 1817–1818
Authors: Shields Juliet 
Published: July 2023

Scott’s Waverley novels often turn on an opposition between romance—the realm of the unexpected, marvellous and heroic—and real life—the often disappointing realm of the mundane and factual. However, Rob Roy, offers readers no alternative to romance. Instead it is made up of different kinds of romance—namely the gothic and the adventure story or imperial romance. Scott maps the genre of the gothic onto Northumberland, where the remnants of feudalism still prevail, and wealth consists in landed property transmitted across generations. The adventure story, by contrast, links the Scottish Highlands with southern metropolitan Britain through a system of speculation and credit. Rob Roy reflects on Scott’s imbrication in these two systems at the time of the novel’s writing—a period of economic depression and rural depopulation—as he sold metropolitan readers another romanticized image of the Highlands in order to shore up his own landed property.
