Revisiting placebo
Authors: Kirkwood Craig
Published: February 2023

The placebo effect refers to the phenomenon in which a treatment or intervention that is not inherently therapeutic, such as a sugar pill or saline injection, can produce a measurable improvement in a patient's symptoms or condition. The exact mechanisms behind the placebo effect are not well understood, but it is thought to involve the release of endorphins, the body's natural pain-relieving chemicals, and the activation of the brain's reward and pain-regulation systems. This article reviews recent research into the efficacy of the placebo in general practice.
Augmented renal clearance in the intensive care units: concepts to considerate in drug dosing
Authors: Charco-Roca Luisa M.
Published: February 2023

Augmented renal clearance (ARC) is a manifestation of renal function that can be seen in patients admitted to the Intensive Care Unit. Its exact prevalence is unknown and it is detected by way of an urinary measurement of creatine. ARC is defined as a creatinine clearance greater than 130 ml / min / 1.72 m2. Pathological mechanisms are not clearly defined and are probably multifactorial. For patients with confirmed ARC, dosing modifications of all renally purified medicinal products should be taken into account. The use of conventional doses can lead to the failure of the therapy with worse results for the patient and a higher economic cost for the healthcare system. Future research will determine dosages in ARC cases and the use of drug plasma concentration measurements will help us to individualize treatments.
On the Einstein relation between mobility and diffusion cofficint in an active Nanostructured Materials
Authors: Singha Roy Subhamoy
Published: February 2023

It is commonly known that the speed at which contemporary switching semiconductors work much depends on the carrier degeneracy of the band. Furthermore, the relation of the diffusivity to mobility ratio of the carriers in semiconductors (referred to as DMR) is very helpful because it is more accurate than any of the individual relations for diffusivity to mobility ratio, which is thought to be the two most frequently used parameters in carrier transport in semiconductors. With n-InSb and Hg1-xCdxTe as examples of numerical calculations, we will examine DMR under strong magnetic quantization of III-V in line with the three- and two-band models of Kane, respectively, along with parabolic energy bands.

Surveying methods and instruments for heritage properties, using decision tree and Artificial Neural network analysis
Authors: Roka-Madarasz Livia
Published: February 2023

This paper demonstrates the application of surveying methodologies aiding the management of heritage properties, especially for UNESCO World Heritage sites. The objective of the current study is to provide an overview of the historical background of surveying a particular field of engineering and the related social environment. In Europe, all types of historic streets and avenues share a centuries-long common history. Investments financed by governments, capital or residential sources relating to these streets have provided opportunities for interesting architectural experiments. This study demonstrates the intensity of these investments and the morphological and functional changes in relation to their distance from the CBD. To achieve this objective, based on an on-line database of housing features and values, apartments (n = 1,031) from the range of Residential Real Estates in Teréz Town Budapest were collected. Data statistics tools included a Decision Tree and an Artificial Multi-layer Neural Network employed in order to analyse inequalities in price according to the condition of the property and available conveniences. The characteristics of monocentricity/polycentricity are shown to be adaptable elements that have been used historically in urban landscapes and can be implemented in urban design to enhance green spaces and improve the overall quality of urban life. As good examples, the Andrássy/Hübner - Court and the ICOMOS prize-winning renovation of the Wahrmann Palace are presented. Real estate can carry both real and philosophical meaning. Sometimes buildings express physical reality in the environment, at others, they have a symbolic meaning, e. g. an urban idyll, harmony with the habitat, local community, heritage property, wealth or poverty, integration or segregation of people or families. Functional changes support long-term decision-making for investors and city residents in search for better locations within global cityscapes.
High Culture and Experience in Ancient Egypt
Authors: Baines John
Published: February 2023

This novel work uses case studies of both familiar and unfamiliar materials, expanding consideration of ancient Egyptian elite culture to encompass lived experience and exploitation of the natural environment. The opening chapter sets out the conceptual ground for the analyses that follow, arguing that the relatively ephemeral activities under investigation were centrally important to the actors. The first and largest study treats human organization of the landscape and its use to create and transmit elite meanings, especially through pictorial and encyclopaedic forms, and to mobilize emotional values. Next, a treatment of the planning of primarily third millennium settlements on the floodplain argues that Egypt offers a partly rural perspective that provides an alternative to the urban focus of many early civilizations but has parallels in elite culture in much of the world. The third study discusses how a single year’s events were orchestrated to culminate in a celebratory hunt in which the king, his court, and high officials participated. The concluding chapter presents an initial synthesis of Egyptian treatments of elite experience, drawing in particular upon additional evidence from literary texts and attitudes to travel. Throughout the book, aesthetics and the cultivation of pleasure and delight are emphasized as essential to ancient elite life.
Religion Evolving: Cultural, Cognitive, and Ecological Dynamics
Authors: Purzycki Benjamin Grant , Sosis Richard
Published: February 2023

The scientific study of religion has made significant advances in recent decades, explaining how the mind produces religious ideas, the motivations underlying religious behaviour, and the transmission of religious cultures within and across generations. In Religion Evolving: Cultural, Cognitive, and Ecological Dynamics, Purzycki and Sosis argue that further progress requires integration of isolated research findings on the various components – ritual, supernatural agent belief, myth, taboo, and so forth – that constitute religion. Religions, they contend, need to be understood as adaptive systems. Drawing from a wealth of ethnographic and experimental evidence, they situate religious systems within their local socioecological contexts, showing how religious culture adaptively responds to economic, environmental, and human health problems, as well as costly threats to cooperation and reproduction. Based in the evolutionary, cognitive, and anthropological sciences, Religion Evolving offers a holistic approach that attends to the complex, interacting features of religious systems.
Studying-Teaching-Evaluating Religions
Authors: Yong Amos
Published: February 2023

One version, albeit in many circles the dominant one, of the scholarly study and teaching of religion interfaces with theological ideas of religious traditions usually only at the descriptive level. Yet the study and teaching of religions also involves evaluation of such, whether implicitly or intentionally, and these usually occur at the ideational level. This essay seeks to illuminate these operations from a comparative theological perspective, suggesting how the study, teaching, and evaluating of religious traditions in their multi-facetedness works both comparatively and theologically. We will spring off The Comparative Religious Ideas project from almost two decades ago both because of how it presented a marked improvement over prior approaches to religious comparativism and because of its prescience then in charting the terrain. From there, however, we will explore how the studying, teaching, and evaluating of religions involves engaging the realm of religious ideas with their concomitant (embodied) practices and from that perspective, the comparative task is both complexified and deepened. Our conclusions propose how to nurture comparative methodologies at both the cognitive and affective domains in order to further discussion in the study, teaching, and evaluation of religion.

El tema de la economía en Leonardo Polo
Authors: García-Muñoz José-Alpiniano , García-Giraldo Alba-Isabel
Published: February 2023

La economía en Leonardo Polo se ocupa de estudiar el accionar de las personas humanas. Su visión corrige el reduccionismo de quienes limitan el saber económico al análisis de precios, mercados y determinación de rentas individuales y excluyen el estudio de los fines humanos. Para el efecto se sirve de su antropología trascendental, distinguiendo en el hombre naturaleza, esencia y ser personal; sin limitarse a traslapar sino investigando mediante los métodos distintivos del saber estrictamente económico. Sostiene que sólo una organización que integre aquellas tres dimensiones permite un verdadero ex-sistir humano. La empresa reúne tal condición.

Adrenalina
Authors: Enríquez Meza Rodrigo
Published: February 2023

La adrenalina es una sustancia química que se produce en la médula de las glándulas suprarrenales, en conjunto con la noradrenalina, conocidas como catecolaminas, son sustancias que estimulan a las células corporales. La adrenalina puede comportarse como hormona cuando se vierte en la sangre y su efecto puede ser más prolongado que cuando se comporta como neurotransmisor en las sinapsis neuronales, donde cumple la misma función que en otros tejidos pero en un espacio más corto de tiempo. Tanto la adrenalina como la noradrenalina son esenciales para que el cuerpo se prepare para sobrellevar una emergencia o un evento que sea interpretado por el sistema nervioso como peligroso; por lo tanto, son consideradas sustancias vitales en el sistema simpático, responsable de la activación fsiológica del organismo cuando así lo requiere. Finalmente, es importante considerar que en el ejercicio y en el deporte las necesidades del cuerpo están incrementadas y por tanto el organismo libera adrenalina para cumplir con las funciones metabólicas aumentadas que una persona necesita para desarrollar dichas actividades. El propósito de este artículo es servir de apoyo académico en la asignatura de Fisiología del ejercicio que cursan los estudiantes de la Licenciatura en Educación Física.
THERMAL AND FLOW ANALYSES OF PERFORATED SERRATED ANNULAR FINNED-TUBE BUNDLES IN A CROSS-FLOW HEAT EXCHANGER
Authors: Taçgün Ekrem , Aksoy İ. Gökhan
Published: February 2023

The thermal and flow analysis of a cross-flow heat exchanger is numerically investigated by experimental validation in this study. The cross-flow heat exchanger consists of a tube bundle with perforated serrated annular fins. Numerical analysis is performed in three dimensions by using the ANSYS Fluent program. Numerical studies are validated separately for thermal and flow characteristics. For the validation study, experiments are performed on a cross-flow heat exchanger experimental setup at five different Re numbers. The numerical results are found to be in agreement with these experiments using the appropriate turbulence model. Perforated serrated annular finned-tube bundles are compared with the existing tube bundles in the literature such as annular solid and serrated finned-tube bundles in terms of heat transfer and flow friction. As a result of the numerical analyses, heat transfer of the perforated serrated finned-tube bundle is 14.2% and 5.2% higher than that of solid and serrated finned-tube bundles, respectively. At the same time flow friction of the perforated serrated finned-tube bundle is also higher than that of solid and serrated finned-tube bundles. In addition, the segment height ratio is determined as a variable geometric parameter. This geometric parameter is examined for five Re numbers. The effects of this parameter on heat transfer and flow friction are investigated separately. As a result, it has been observed that drilling of circular holes on the segment section of the annular serrated finned-tube bundles increases heat transfer and flow friction.

Authors: Ermilov Sergey G. , Rybalov Leonid B.
Published: February 2023

A new species of Scheloribates (Perscheloribates) (Oribatida, Scheloribatidae) – S. (P.) oromiaensis sp. n. – is described from mosses on the swamp at the top of the mountain in Arsi Mountains National Park, Ethiopia; the new species differs from the related species S. (P.) ethiopicus by the larger body size, rounded rostrum and pedotectum II, the absence of prolamella, and the presence of aggenital seta. The taxonomic status of Perscheloribates is discussed, resulting in the supporting of it on the subgeneric level within Scheloribates. An identification key to known species of Scheloribates (Perscheloribates) from the Afrotropical region is provided.

Nest entry shape change may cause nest abandonment in urban cavity-nesting species: a case study of the Tree Sparrow Passer montanus
Authors: Lee Ju-Hyun , Kim Se-Yeong , Cho Dae-Han , Sung Ha-Cheol
Published: February 2023

The threat of predation is the main cause of bird nest abandonment, with such behaviour imposing considerable energetic costs on breeding birds. However, for several species, nest abandonment can be a less costly alternative to complete brood failure. In this study, we examined nest abandonment among Eurasian Tree Sparrows (Passer montanus) by surveying 71 Tree Sparrow nests with various types of entry holes and conducted artificially manipulating some of the entrance shapes. We found that nest abandonment was caused by changes to the nest entry shape in seven cases and by human interference in two cases. Nest abandonments occurred throughout the breeding season, and breeding pairs attempted to breed again immediately after nest abandonment. The results of the artificial nest entry shape manipulation experiment showed that nine of twelve nests (75.0%) were abandoned where the nest entrance holes were widened, and six of eleven nests (54.5%) were abandoned where the nest entrance holes were narrowed. However, none of the nests were abandoned where the entry shape was unchanged. Thus, nest abandonment by Tree Sparrows is correlated with nest entry shape manipulation and is more likely to occur when the energy cost of breeding again is less than that of abandoning the nest.
Main functions of loud vocalization in populations of edible dormouse Glis glis
Authors: Jurczyszyn Mirosław
Published: February 2023

The study aimed to determine when, during summer activity, males and females of the edible dormouse most often used loud calls. On this basis, an attempt was made to determine the main purpose of the emission of these calls. It was assumed that 1) if males have the most of loud calls in July, their emissions may be related primarily to the mating behaviour (which takes place during this period), and if they have the most of loud calls in August, their emissions are most likely concerned defence of food resources, 2) in females, most of this vocalization would occur in August due to the need to defend their food resources and 3) in both sexes, more vocalization would occur in the year of good beech fruit crop (when the dormice would reproduce) than in the year of no crop (when the dormice would not reproduce). To check these assumptions, the number of loud calls and “performances” (series of loud calls) emitted by the animals from two wild populations tracked by telemetry was noted. The mean number of “performances” and loud calls in males and females was higher in August than in July (when beech fruits ripen), but significant differences were found only for “performances”. Both males and females had significantly more “performances” and loud calls in the mast/breeding year than in the non-mast/non-breeding year. It seems that males and females use loud calls mainly to defend important resources and are, therefore, most often heard during the mast year.
Effect of Complex Training on Aerobic and Anaerobic Power of Amateur Athletes
Authors: Kumar Gopal , Pandey Vivek
Published: February 2023

The study purpose was to investigate the effect of complex training on aerobic and anaerobic power of amateur athletes.
Materials and methods. The study included 30 amateur athletes in soccer and hockey, which were equally divided into two groups, namely an Experimental group who underwent 6 weeks of complex training along with regular training in their sports and a Control Group who only performed their regular sports training. Anaerobic power was assessed by Running-based Anaerobic Sprint Test (RAST) and aerobic power (VO₂max) was assessed by 12-min Cooper run/walk test. The study used the Pre-test Post-test Randomized Group Design, and Paired t-test was used as the statistical technique for data analysis at a significance level of 0.05.
Results. At the end of six weeks, the Experimental group showed significant improvement in anaerobic power and VO₂max, while only VO₂max was improved in the Control group (p<0.05). No significant improvement was observed in anaerobic power for the Control group (p>0.06). Therefore, this shows that complex training has significant effect on anaerobic power, while it does not produce significant improvements in aerobic power.
Conclusions. Six weeks of complex training integrated with regular sports training can improve anaerobic power. Coaches and athletes, specifically in soccer and hockey, can implement the complex training program in their regular training.

Published: February 2023

Background. Bodybuilding is a sport where a person should do a lot of weight training while in the same time having a strict diet control. Due to this, they are believed to have higher chances of getting injured. However, lack of research has been conducted on the incidence of injuries and the treatment history among bodybuilders in Thailand. Therefore, the purpose of this study was to investigate and compare the incidence of injuries and treatment experience between elite and beginner Thailand bodybuilders.
Material and methods. 157 bodybuilders who were registered as members of the Thailand Bodybuilding and Physique Sports Association (since 2020-2021) were recruited as participants in this study. They were divided in to two groups, namely elite (more than 5 years of sports training) and beginner (less than 5 years of sports training). A valid and reliable questionnaire was used to collect the data from the participants.
Results. There was no significant difference in the most common period of injury between the beginner and elite groups. The most common period of injury for both groups was found to be during diet period (beginner 55.43%; elite 55.38%) followed by bulk period, off season and competition period, respectively. For the injury area, there was no difference between the groups, with the lower back (beginner 63.04%; elite 52.31%) being the most common area of injury, followed by shoulder, chest, finger and wrist. There was also no significant difference in treatment between the groups in the first 48 hours after injury. Most of the athletes in both groups had rest (beginner 80.43%; elite 81.53%) and applied cold (beginner 61.96%; elite 73.85%) to their injury area. Additionally, the beginner group of Thai bodybuilders visited the physical therapist more often than the elite group did (p < 0.01). At the same time, there was no significant difference in medical doctor, sports scientist, coach and self-treatment and rehabilitation between both groups. However, most of athletes from both groups mainly resorted to self-treatment.
Conclusions. The study findings are expected to be valuable for the bodybuilding association, coaches and athletes to take extra precautions regarding injury in the future.

Authors: Geghamyan Vardan , Tarjumanyan Silvi
Published: February 2023

The work is based on the discussion of psychological problems in modern chess, which are significantly related to the rapid growth of chess competitiveness  in recent years, the frequency of participation in competitions, the intensity of competition and other similar manifestations.

The study purpose. We tended to identify the most important psychological indicators that ensure the effectiveness of the chess player's competitive activity, to describe their correlational relations and the peculiarities of their manifestation.

Materials and methods. The research process was carried out with interconnected laboratory-instrumental and non-instrumental methods, which are of great practical importance in psychology: questionnaires, tests, observations, mathematical statistical methods, as well as self-made "psychodiagnostic multifactorial" equipment. The research was organized among 30 grandmasters in the National men's chess team of the Republic of Armenia through different years, winners of the World Olympiad, World team tournaments, and the World Cup. It targeted the study of the four main areas of a chess player's psyche: competitive mental reliability, individual psychological characteristics, emotional states and emotional abilities.

Results. As a result of the analysis of correlations, the following 8 patterns were singled out from 52 examined psychological indicators: stability to internal uncertainty stressors, competitive emotional endurance, personal anxiety, energetic sphere of competitive motivation, psycho-regulation, mobilization preparedness, attention features and complex motor reaction speed. We consider the selected indicators as the leading psychological factors that ensure the competitive process of the chess player.

Conclusions. Effective manifestations of selected psychological indicators can enable a chess player to perform in a more stable and effective way during decisive competitions. The selected indicators can also describe the level of sports training of a highly qualified chess player and serve as model characteristics of psychological service.
