SARS-CoV-2 pandemic is now a global medical and social problem. Little is known about its impact on some vulnerable subgroups, such as immunocompromised patients. Therefore, there is still a strong interest in exploring the impact of SARS-CoV-2 infection among HIV-positive individuals worldwide.   Aim of the study: to analyze immunological aspects of the deceased patients with HIV/COVID-19 coinfection.   Materials and methods. We provided retrospective analysis of 258 patient’s electronic medical records. All patients were admitted to the Infectious diseases hospital № 2 with HIV / COVID-19 coinfection and died in May 2020 – February 2022. Standard immunological parameters were analyzed like CD4+, CD8+ counts and immunoregulatory index for different patient’s subgroups. Statistical data processing was provided by SPSS 17 version (allowable error E = 5 %).

   Results and discussion. The study demonstrated CD4+ and CD8+ reduction in HIV-infected with COVID-19. Late HIV-presenters didn’t display such phenomenon probably because of immune system exhaustion. COVID-19 itself in some cases could lead to immunodeficiency worsening due to depletion of T cell populations in HIV-patients on effective antiretroviral therapy.   Conclusion. Comprehension of different immunological characteristics in HIV / COVID-19 coinfected patients could improve therapeutic approaches for this challenging cohort.

According to the World Health Organization, sustained virological suppression of 90 % should be achieved among children and adolescents living with HIV / AIDS, which makes it important to assess the prevalence of virological failure of antiretroviral therapy.   The aim of this study was to determine the prevalence of virological failure and the clinical factors associated with it, as well as therapeutic drug monitoring in groups divided by the viral load level among children and adolescents with HIV.   Materials and Methods: A retrospective analysis of the medical records of 184 children and adolescents receiving antiretroviral therapy and registered at the Irkutsk Regional Center for the Prevention and Control of AIDS and Infectious Diseases, Irkutsk, was carried out. The study included 172 children aged 1-18 years with perinatal HIV infection. Patients were divided into groups depending on the level of viral load: group 1 – 21 patients with viral load > 1000 copies/ml of plasma, group 2 – 42 patients with viral load 50– 1000 copies/ml of plasma, group 3 – 109 patients with undetectable viral load (< 50 copies/ml). All patients underwent standard tests in accordance with clinical guidelines for the treatment of HIV infection in children, as well as therapeutic drug monitoring.   Results. Against the background of ongoing antiretroviral therapy, a significant number of patients 21 / 172 (12,2 %) experienced virological failure. The proportion of children and adolescents with incomplete suppression of HIV replication is 42 / 172 (24,4 %). Statistically significant differences were obtained by changing the ART regimen (p = 0,031). In the first group, the proportion of patients who changed the therapy regimen is 7 / 21 (33,3 %), which is two times less than in the group with a zero viral load of 70 / 109 (64,2 %). There are differences in the proportion of children and adolescents with zero concentrations of ritonavir and lopinavir (p = 0,020 and p = 0,012) in the three compared groups. The distribution of patients with zero concentrations was as follows: for ritonavir in the first group 3 / 17 (17,6 %), in the second – 8/37 (21,6 %), in the third group – 4/80 (5 %); for lopinavir – 4/17 (23,5 %), 6/36 (16,7 %), 3/80 (3,8 %), respectively.   Conclusion. This study demonstrates that the prevalence of virological failure among children and adolescents receiving ART remains high. To achieve sustained virological suppression in children and adolescents taking a protease inhibitor regimen, adherence to therapy must be increased. As one of the methods for assessing adherence, therapeutic drug monitoring can be used.

Cybersecurity is a problem that is rarely discussed by the public, especially among university students in Malaysia. This study aims to determine the significant differences of cybersecurity awareness between genders and to investigate the significant predictors of the cybersecurity awareness. This study adopts a cross-sectional methodology among UiTM Negeri Sembilan, Seremban Campus students (n=201, 19 to 25 years old) using a questionnaire. The results show that male and female students have the same level of cybersecurity awareness. Meanwhile, gender, age, marital status, faculty, type of social media used, hours spent on social media, attitude and environmental factors do not in any way affect the awareness of cybersecurity among students. The results further show that it is only the knowledge factors that differentiate cybersecurity awareness among them.

The aim of the present study was to identify the adaptability of Normandy cows raised in a loose system to the climatic and technological conditions and to compare their adaptability with already acclimatized Simmental cows in one farm in Southwestern Bulgaria. Total of 20 cows at same age (II – IV lactation) and same body weight (630-660 kg) from both breeds were classified into 2 groups (each having 10 cows) and subjected to skin thickness measurement, fibers total weight determination and fiber categorization during the winter and summer season. The results have shown that during the winter season, the Normandy breed had significantly higher skin thickness at the elbow compared to the Simmental breed, whereas no differences were observed in the skin thickness between both breeds either at the neck or at the middle of the last rib. During the summer season, the differences on the skin thickness compared to the Simmental breed were observed at the neck (p<0.05), whilst at the elbow and at the middle of the last rib no differences were recorded (p>0.05). During the winter seasons, the coat of Normandy cows contained more soft fibers in comparison to the Simmentals cows. Furthermore, the changes in the observed parameters, influenced by climatic conditions showed similar pattern in both breeds. It can be concluded that the two breeds have emphasized their genetic potential and have a good adaptability to the temperate continental climate of the region.

Published: January 2023

The objective of this study was to examine the effect of ketoprofen with or without combination with xylazine on the level of cyclooxygenase-2 in mice. The intraperitoneal (i.p.) dose of ketoprofen and xylazine that caused an analgesic response in half of the mouse population was 1.26 mg/kg and 6.63 mg/kg, respectively. Serum cyclooxygenase-2 concentration (activity) in the control mice was 16.94 ng/ml. The ketoprofen-treated group (2.52 mg/kg, i.p.) decreased the cyclooxygenase-2 concentration by 58% (7.16 ng/ml). The combined ketoprofen and xylazine treatment (13.26 mg/kg, i.p.) decreased the cyclooxygenase-2 by 94% (0.98 ng/ml). The ketoprofen plasma concentration in the combined treatment group was significantly higher compared to the ketoprofen treatment group. Ketoprofen plasma concentrations measured at 0.25, 0.5, 1, 2, 4, and 24 hours were 19.07, 18.94, 14.66, 6.53, 5.44, and 5.54 µg/ml, respectively. Plasma concentrations of ketoprofen and xylazine were raised to 28.74, 29.74, 15.32, 13.04, 14.64, and 11.95 µg/ml or by 51%, 56%, 5%, 100%, 169%, and 116%, respectively. Ketoprofen pharmacokinetic variables were increased (AUC0-∞ (515%), AUMC0-∞ (2389%), MRT (305%), t1/2β (375%), Tmax (100%), and Cmax (55%)), while other values were decreased (Kel (79%), Vss (25%), and Cl (88%)). Our findings suggested a synergistic interaction between ketoprofen and xylazine on the level of cyclooxygenase-2 (pharmacodynamic interaction) which was exerted by modification of the ketoprofen pharmacokinetic properties in mice.

Authors: Kasianov Vladimir Aleksandrovich , Goncharenko Andriy Viktorovich
Published: January 2023

This paper proposes a solution to a certain macroeconomic model. A multi-alternative problem of aviation transportation optimal organisation in conditions of uncertainty of the subjective preference functions is considered. Conditional optimisation of the objective functional containing the entropy of the individuals’ operational effectiveness functions preferences is carried out in the framework of the simplest macroeconomic problem. The principle of the Solow and Cobb–Douglas models, similar to the approach adopted for the estimation of economic growth, is modified with the subjective entropy maximum principle. The advantages of the described optimisation approach are demonstrated in the generalised terms of the operational effectiveness functions for aviation transportation organisation.
Optimisation of a Nacelle Electro-Thermal Ice Protection System for Icing Wind Tunnel Testing
Authors: Gallia Mariachiara , Carnemolla Alessandro , Premazzi Marco , Guardone Alberto
Published: January 2023

Aircraft are equipped with ice protection systems (IPS), to avoid, delay or remove ice accretion. Two widely used technologies are the thermo-pneumatic IPS and the electro-thermal IPS (ETIPS). Thermo-pneumatic IPS requires air extraction from the engine negatively affecting its performances. Moreover, in the context of green aviation, aircraft manufacturers are moving towards hybrid or fully electric aircraft requiring all electric on-board systems. In this work, an ETIPS has been designed and optimised to replace the nacelle pneumatic-thermal system. The aim is to minimise the power consumption while assuring limited or null ice formation and that the surface temperature remains between acceptable bounds to avoid material degradation. The design parameters were the length and heat flux of each heater. Runback ice formations and surface temperature were assessed by means of the in-house developed PoliMIce framework. The optimisation was performed using a genetic algorithm, and the constraints were handled through a linear penalty method. The optimal configuration required 33% less power with respect to the previously installed thermo-pneumatic IPS. Furthermore, engine performance is not affected in the case of the ETIPS. This energy saving resulted in an estimated reduction of specific fuel consumption of 3%, when operating the IPS in anti-icing mode.

Published: January 2023

En este estudio se realiza una estimación de la recarga potencial por infiltración de lluvia en la zona norte de Loreto en el estado de Baja California Sur, México, donde se incluyen las cuenca de Gombedor, Loreto y San Bruno; ello, en respuesta a la escasa información en el área y la urgencia que representa la presión sobre los recursos hídricos. A partir de datos de precipitación y temperatura de las estaciones climáticas cercanas al municipio de Loreto se realizaron modelos de precipitación y temperatura mediante el método de interpolación Kriging; con estos modelos se calcularon la evapotranspiración, el escurrimiento y finalmente la infiltración potencial. Los resultados obtenidos fueron de 5.37 Mm3 año-1 para la cuenca de Gombedor, 13.37 Mm3 año-1 en la cuenca de San Bruno y 7.62 Mm3 año-1 en el norte de Loreto. En la cuenca San Bruno se encuentran los pozos de extracción que surten a la ciudad de Loreto, aquí se estimó una recarga potencial de 1.97 Mm3 año-1 con una precipitación media anual de 207 mm. La infiltración por la lluvia es una de las fuentes más importantes de recarga de los acuíferos, junto con los flujos subterráneos, y la recarga artificial o inducida. El modelo hidrogeológico conceptual permite abordar más fácilmente la situación de la cuenca para elaborar estrategias de manejo. Este tipo de modelos puede resultar eficiente donde no hay aguas superficiales, ya que brinda un buen pronóstico para zonas con pocos datos o que son difícil acceso mediante el uso de técnicas de sistemas de información geográfica y geoestadísticas.

Published: January 2023

In this study, in order to evaluate the change of LST from rural to urban scale in 20 years, a zoonal statistical analysis was performed by separating the urban and rural districts located on the coastline. Algorithms were applied to the raw data of Landsat 8 and Landsat 7 satellite images, using the Arc Gis 10.2 and Q Gis 3.16 utilities. In this way, NDVI, NDBI and LST data were compared and evaluated in terms of rural and urban districts. The correlation coefficient between the parameters was calculated. In the study, the land change between the years 2000-2020 was also determined to reveal the land change. As a result of the analyzes made, the amount of green areas decreased by 14.1% between 2000 and 2020 in the study area, which includes the central districts of Samsun, İlkadım and Atakum, and in the rural areas, Bafra and Ondokuz Mayıs. It has been observed that this rate is shared as 7.1% in built up areas and 7.33% in bare soil areas. Considering the effect of the decrease in green areas on the LST value, in 2000, max. While LST is 41.75 C, in 2020 max. It is seen that LST has increased to 43.44 C. When the districts were analyzed separately, it was seen that LST established a strong correlation with NDBI (positive) and NDVI (negative) for all four districts. However, the correlation was stronger in rural districts. It was observed that the correlation strength weakened in urban districts due to heterogeneous land surface cover.
Evaluation of Waste with High Organic Content in Energy Production
Authors: Bayrak Işık Esin Hande , Kalpakçı Yokuş Semire
Published: January 2023

Animal and vegetable wastes are mostly utilized by burning or as fertilizer on agricultural lands. Burning these wastes does not produce a desired level of heat, and the remaining material after heat production cannot be used as fertilizer, either. For this reason, plant and animal wastes are converted into energy by obtaining biogas from biomass, which is one of the most environmentally acceptable methods of solution. This system makes it possible to both produce energy and evaluate the end product as fertilizer. In this study, the efficiency of biogas and methane production from kitchen waste and ovine manure via anaerobic fermentation was evaluated. First of all, the C/N ratio of randomly selected kitchen wastes was determined, and it was found as 34.30. The mixing ratios with ovine manure were determined by considering the C/N ratio that was found. The mixing ratios of kitchen waste and ovine manure by mass were determined as 1:0, 0:1, 1:1, 1:2, and 2:1, respectively, and the C/N values providing optimum biogas production in the mixtures were found. At the end of the 48-day-long anaerobic fermentation process, the highest biogas and methane production was achieved as 525 ml and 332 ml, respectively, in reactor 5 with a mixing ratio of 2:1. This reactor was followed by reactor 2 with 450 ml of biogas and 271 ml of methane production. Accordingly, it was concluded that kitchen waste could be a good mixture with ovine manure in anaerobic fermentation.

Authors: Hussein Sawsan Ramadhan , Rashid Sherzad Khorsheed
Published: January 2023

Background and aims: Gingivitis in orthodontic treatment remains a challenging and undesirable consequence of orthodontic treatment. Hence, a variety of chemical or herbal agents, methods, and techniques have been investigated to prevent or reduce gingivitis that occurs in orthodontic treatment. In this study, we will evaluate and compare the effect of curcumin (CMN) gel with chlorhexidine (CHX) gel on clinical parameters (plaque and gingival index) and oral bacterial number (total bacterial count test) in fixed orthodontic patients that have gingivitis. We are the first to use curcumin gel for patients that have gingivitis with fixed orthodontic appliances. Samples and Methods: Forty-five patients with fixed orthodontic appliances with metallic brackets that have generalized chronic dental plaque-induced gingivitis were selected randomly and divided into three groups - Group I (control), Group II (CMN), and Group III (CHX), respectively. Clinical parameters which are plaque index (PI) and gingival index (GI) were recorded at the baseline, 14 days, and 21 days of treatment, and a total bacterial count test (TBCT) was done for all the participants before and after treatment. Results: Both Curcumin and Chlorhexidine gel groups showed a significant reduction (P<0.05) in PI, GI, and TBCT compared to the control group at the end of treatment (after 21 days). However, there was no significant difference between Curcumin and Chlorhexidine gel groups (P>0.05). Conclusion: The results of this study show that curcumin and chlorhexidine gel have comparable anti-plaque, anti-gingivitis, and antibacterial activities and that both can be used to effectively treat plaque-induced gingivitis.

Authors: Mikail Abdulrazaq Qasim , Hamad Rahel
Published: January 2023

Flood hazards are a member of the world's catastrophic events with a hydrological climate origin. They are referred to as a situation in which the river flow and water level increase suddenly and cause human and financial losses. This research aims to determine flood-prone zones and evaluate the efficacy of RS and GIS-based evidence-based belief function (EBF) and hierarchical analysis (AHP) models in flood-prone area mapping. Using the Rezan River basin in the Mergasor area of Erbil governorate, Iraq, as an example, 11 factors such as slope, slope direction, land use, distance to the stream, distance to the road, elevation, soil, rainfall, geology, NDVI, and drainage density were utilized for flood moderation. The prediction rates of the EBF and AHP models were also analyzed to be 0.869% and 0.836%, respectively, indicating that these two models are better predictors. The findings of the study area revealed that 32% of the study area is under very high to high flooding hazard zones for the EBF method and 22% for the AHP method. This research’s conclusions are crucial for flood-prone region management, decision-making, and local administrative planning.

Published: January 2023

Lettuce (Lactuca sativa L.) is considered as the most cultivated and consumed leafy vegetable all over the world. In Erbil Governorate, most farmers used sewage water to irrigate lettuce, which caused health risks especially heavy metal pollutants including cadmium. This research was applied as a factorial experiment to investigate the effects of foliar spraying of salicylic acid (SA) (0,0.5,1, 1.5 or 2mM) followed by spraying cadmium chloride (Cd) (0, 1, 2, or 4mM) on the growth, and some physiological and biochemical characteristics of this plant. Results show that most vegetative growth characteristics responded inversely to increasing SA concentrations, whereas the response of root performance improved with using SA application. A low concentration of Cd (1mM) improved root and shoot performance, whereas increasing the concentration to 4 mM decreased these characteristics significantly compared to no Cd added plants, except for the percent of shoot dry matter. Most of photosynthetic pigments decreased significantly by foliar spraying with SA and Cd. Applications of SA increased catalase enzyme activity significantly compared to no SA treated plants. Cadmium foliar application increased peroxidase enzyme activity, ascorbic acid, proline, and percent of total carbohydrate content and decreased catalase enzyme activity and the percent of infection with watery soft rot significantly compared to no Cd treated plants. It is concluded that lettuce tolerance to cadmium stress was increased by pretreatment foliar application of SA.

An Initial Study of Disclosures Related to Responsible Investing Implementation: A South African Perspective
Authors: Jacobson Lori , Varachia Zakiyyah , Van Zijl Wayne
Published: January 2023

Purpose:  Financial institutions (FIs) such as banks, insurance companies and pension funds have a significant impact on the environment through the financing they provide. Mining and oil and gas companies receive funding and use this for different projects which may have environmental consequences. This study examines the extent to which both the grantor and the receiver of finance identify and apply responsible investment (RI) practices when making investment decisions

Design/methodology/approach: A detailed literature review was used to construct a disclosure checklist to assess the implementation of RI principles. The population is all companies listed in the financial services, banks, mining and oil and gas sectors of the Johannesburg Stock Exchange (JSE), who had published integrated reports.

Findings: The results of this research indicate that the extent of RI disclosure in FIs in South Africa is limited. The extent of RI disclosure for the mining and oil and gas companies is stronger than for FI’s.

Originality/value: At present, there are no studies which have investigated the disclosure of RI principles applied in South Africa. This study constructed a RI disclosure checklist, drawing on the principles of RI to understand the implementation of RI in South Africa.

Published: January 2023

Objective: To express the usage of intelligent concepts in the architectural building construction field that are primarily concerned with reducing building energy use. Improved energy-saving methods and the use of environmentally friendly design principles are essential in this field. This type of managerial decision-making is necessary for the success of these types of projects. Methods: monitoring the performance of intelligent buildings use the cost variance (CV) and schedule variation as standard metrics to track the progress of a project based on the save energy concept. Also, this research conducted a comparative study on Building Information Modelling (BIM) and (MCDM) decision-making limitations as presented in the article. Analysis: the conventional technique, on the other hand, is unable to offer data on variance from typical performance levels. The main point based on Delphi results of construction cost variables has been observed 19 effective factors. Finding and Novelty: The RII observed that the most effective aspects of an intelligent building are the number of floors in the building, the kind of structural design, and the size of the shadow cast on the surface of the building. The Multi-Criteria Decision Maker (MCDM) observed significant differences in planned value (PV) and actual value (AC) results. In addition, as a result of the current approach, it is possible to track project costs and timelines more precisely. Doi: 10.28991/CEJ-2023-09-01-010 Full Text: PDF

Published: January 2023

The consideration of payments to contractors is not only a legal obligation but a necessity for assuring the continuity and completion of a construction project. However, consistent payments to facilitate project cash flows are uncommon in the construction industry. Within the context of a small island developing state, this paper aims to uncover leading risks factors the contributing to implications of delayed payments, on contractors’ cash flows and uncover any causalities and effects on relationships among these factors. A two-tiered quantitative approach was adopted. Firstly, a compiled list of delay factors was collated from the literature review. Semi-structured interviews were conducted with experienced construction professionals to determine the factors’ relevance and applicability in Trinidad and Tobago. A closed-ended survey questionnaire was subsequently developed and administered to primary construction stakeholders. Secondly, the responses obtained were collated, validated, and ranked using the relative importance index. A confirmatory factor analysis (CFA) was carried out using SPSS, and thereafter, SPSS Amos was used to determine the best-fit Structural Equation Model (SEM). The results strongly indicate that the issue of delayed payments is very prevalent within public sector projects. Unstable political climates and the delay in employers’ issuance of variation orders were found to be the main causes of delayed payments within the industry. Delays in sub-contractor and supplier payments as well as an increase in the contractor’s debt are the leading effects of delayed payments on the contractor’s cash flows. Based on these findings, a risk response framework was outlined to assist small to medium-contracting enterprises cope with payment delays, both locally and internationally. This research contributes to the advancement of construction management knowledge by informing construction professionals and policy makers of the implications of delaying approved payments, the consequential causes and effects, and a risk response technique to mitigate the negative effects on contractors’ cash flows. Doi: 10.28991/CEJ-2023-09-01-05 Full Text: PDF
