Published: April 2021

The nature of sociology and psychology is clarified accounting for the achievements of modern philosophy of science. The general scientific significance of these sciences is determined in accordance with said clarification. Any scientific theory functions, in particular, in the form of group and individual theories. In this connection, the general scientific significance of sociology and psychology becomes evident. The status of sociology is primarily determined by the study of group theories that have general scientific significance. The status of psychology is determined by individual theories. Its priority in this area is also indisputable. Therefore, same as sociology, psychology presents a science of auxiliary nature. Auxiliary sciences are necessary for the development of the content of the independent sciences. Unfortunately, the mainstream tendency is that both sociology and psychology are considered independent branches of science. In this regard, the status of sociology is determined by a certain class of social phenomena, and the status of psychology is determined by mental processes.

Published: April 2021

The article aims at studying the legal nature and essence of constitutional proceedings with due regard to historical experience and modern legislative approaches to the structure and system of constitutional justice in Russia. The main research method was the deductive method which allowed the authors to study the legal nature of the Constitutional Court and its role in the separation of powers in Russia. The article also used the inductive method, the method of systemic analysis, and comparative-legal and historical methods. To solve the research problem, it is necessary to consider the legal foundations and features of constitutional justice based on the amendments made to the Constitution of the Russian Federation on July 1, 2020. The article proves that the legal nature and the main goal of constitutional control remain unresolved issues. According to the authors, the most important condition for the creation of a strong judicial power is its high independence. Judicial errors can also cause distrust in the judiciary.
The ambiguity of happiness education in the context of positive education: A critical analysis
Authors: Gilyazova Olga Sergeevna , Zamoshchanskii Ivan Igorevich
Published: April 2021

The article aims to analyze the place and significance of happiness in educational discourse. The analysis reveals ambivalence of happiness education, following positive education patterns. The ambivalence stems from the fact that happiness is narrowed down to the first component of the following dichotomies: subjective/objective, active/passive, individual/social. As we explain in our article, such clipped happiness education may involve the following consequences: necessitating ‘therapeutic education’ for students; neglecting matters of social justice; imposing ideas of happiness on a child through ideological indoctrination. Yet, we can conclude that the dual potential of positive education methods makes it possible to offset the above and other adverse consequences of the promoted idea of happiness.

As technology develops in the automotive world, more and more motor vehicle manufacturers are also applying the latest technologies, especially for vehicles sold in general. Call it, for example, the development of the fuel system, which was still a carburetor, now uses an injection system, from S.O.H.C to D.O.H.C. these technologies are useful for increasing volumetric efficiency. In this study, the researchers wanted to increase the volumetric efficiency of the Astro 108 cc engine by applying a simple modification, namely the inlet and exhaust that was modified with a 30 backcut on the valve, undercut system, and 4 angle valve jobs (30 , 45, 60 , 75 ). By applying these modifications to the Astro 108 cc engine, it can increase its volumetric efficiency, say at 2300 rpm with standard inlet and exhaust conditions producing an air flow rate of 0.000358 m3 / s and 0.000814 m3 / s, this data is obtained from pressure taking on the water box meter. The difference in flow occurs because the air that enters the inlet and exhaust is smoother due to the modifications made. With this flow rate, at 2300 rpm standard head produces a volumetric efficiency of 19.05712%, and 43.26364% with a modified head.

Published: April 2021

El tema tratado en este trabajo es el modelado y simulación del motor de CD sin escobillas (BLDC por sus siglas en inglés) incluyendo todos los elementos que garantizan su correcto funcionamiento (sensores y dispositivo de conmutación). Se inicia con la selección de un modelo para el motor que se plantea como punto de partida y que fue elegido a partir de la revisión de diversas referencias relacionadas con el motor BLDC. En la segunda etapa se analiza la incorporación al modelo de elementos tales como, el efecto de saturación magnética, reacción del inducido, para mejorar la precisión en la representación del comportamiento del motor. La simulación del modelo se plantea utilizando los programas: Matlab y Fortran, de forma que el modelo emule todos los elementos físicos; para finalizar se comparan los resultados obtenidos de las simulaciones con mediciones realizadas en un motor BLDC cuyos parámetros son conocidos. La selección del modelo se realizó en función de diversas consideraciones: qué tan fiel es la representación que se logra de las características del motor, la facilidad de programación y el número de parámetros necesarios para realizar la simulación. El modelo que se presenta en este trabajo considera una parte de la no linealidad natural del motor al considerar el efecto de saturación magnética, logrando con esto un modelo más completo sin sacrificar factibilidad de implementación. Para realizar la simulación del motor se consultaron diversas referencias en las cuales se plantean las inconveniencias que surgen al no incluir ciertos elementos físicos como por ejemplo sensores de posición, controladores y dispositivos de conmutación encargados de generar las señales indispensables para el funcionamiento del motor. La simulación se realizó utilizando los parámetros del motor cuya referencia es I2383092NC-Z1XX-SP de la empresa AMETEK TECHNICAL AND INDUSTRIAL PRODUCTS. Por último, se incluye una comparación y análisis de los resultados de la simulación con las señales del bloque Permanent magnet synchronous machine de Simulink y se discute y justifica la validez del modelo utilizado para el desarrollo de este trabajo.

Published: April 2021

OBJECTIVE

To assess signalment, clinical findings, and treatments for New World camelids (NWCs) hospitalized for evaluation and treatment of neonatal disorders and investigate associations between these factors and death during and after hospitalization.

ANIMALS

267 NWCs ≤ 30 days of age.

PROCEDURES

Medical records of a veterinary teaching hospital were retrospectively reviewed to identify NWCs admitted for evaluation and treatment of neonatal disorders between 2000 and 2010. Signalment, physical examination data, diagnostic findings, treatments, and outcomes were recorded. Factors were examined for association with death during hospitalization and the overall hazard of death by use of multivariable logistic regression and Cox proportional hazards analysis, respectively.

RESULTS

The sample comprised alpacas (n = 255) and llamas (12). Median age at admission was 3 days, and median hospitalization time was 2 days; 208 of the 267 (77.9%) neonatal NWCs survived to hospital discharge. Factors associated with increased odds of death during hospitalization included prematurity or dysmaturity, hypothermia, sepsis, toxic changes in neutrophils, and undergoing surgery. The odds of death during hospitalization also increased as anion gap increased. After discharge, 151 of 176 (85.8%) animals had follow-up information available (median follow-up time, 2,932 days); 126 (83%) were alive and 25 (17%) had died. Prematurity or dysmaturity, congenital defects, sepsis, oxygen administration, and undergoing surgery as a neonate were associated with an increased hazard of death; the hazard of death also increased as serum chloride concentration at the time of hospitalization increased.

CONCLUSIONS AND CLINICAL RELEVANCE

Results suggested the prognosis for survival during and after hospitalization is good for most NWCs hospitalized because of neonatal disorders.
Breaking the Contract between God and the Visual-Literary Fusion: Illuminated Manuscripts, William Blake and the Graphic Novel
Authors: Paris-Popa Andreea
Published: April 2021

This essay follows three different stages of the fusion of images and words in the tradition of the book. More specifically, it tackles the transformation undergone by the initially religious combination of visual figures and scriptural texts, exemplified by medieval illuminated manuscripts into the spiritual, non-dogmatic, illuminated books printed and painted by poet-prophet William Blake in a manner that combines mysticism and literature. Eventually, the analysis reaches the secularized genre of the graphic novel that renounces the metaphysical element embedded in the intertwining of the two media. If ninth-century manuscripts such as the Book of Kells were employed solely for divinely inspired renditions of religious texts, William Blake’s late eighteenthcentury illuminated books moved towards an individual, personal literature conveyed via unique pieces of art that asserted the importance of individuality in the process of creation. The modern rendition of the image-text illumination can be said to take the form of the graphic novel with writers such as Will Eisner and Alan Moore overtly expressing their indebtedness to the above-mentioned tradition by paying homage to William Blake in the pages of their graphic novels. However, the fully printed form of this twentieth-century literary genre, along with its separation from the intrinsic spirituality of the visual-literary fusion in order to meet the demands of a disenchanted era, necessarily reconceptualize the notion of illumination.
You’re an Orphan When Science Fiction Raises You
Authors: Halpin Jenni G.
Published: April 2021

In Among Others, Jo Walton’s fairy story about a science-fiction fan, science fiction as a genre and archive serves as an adoptive parent for Morwenna Markova as much as the extended family who provide the more conventional parenting in the absence of the father who deserted her as an infant and the presence of the mother whose unacknowledged psychiatric condition prevented appropriate caregiving. Laden with allusions to science fictional texts of the nineteen-seventies and earlier, this epistolary novel defines and redefines both family and community, challenging the groups in which we live through the fairies who taught Mor about magic and the texts which offer speculations on alternative mores. This article argues that Mor’s approach to the magical world she inhabits is productively informed and futuristically oriented by her reading in science fiction. Among Others demonstrates a restorative power of agency in the formation of all social and familial groupings, engaging in what Donna J. Haraway has described as a transformation into a Chthulucene period which supports the continuation of kin-communities through a transformation of the outcast. In Among Others, the free play between fantasy and science fiction makes kin-formation an ordinary process thereby radically transforming the social possibilities for orphans and others.

Published: April 2021

Solidago graminifolia L. Salisb. is one of the latest species appeared in Romania. Due to the interest for the Solidago species as medicinal plants, we researched its phytochemical composition in comparison with the other three species present in Romania: Solidago virgaurea L., Solidago canadensis L., Solidago gigantea Aiton. Starting from the chemotaxonomic value of flavonoids, and their valuable biological properties, we wanted to analyze these substances from S. graminifolia compared to other Solidago species in Romanian flora. The studied species have a high content of flavonoids (3.44-5.21%). The flavonoid substances identified in the indigenous species of Solidago have a high chemotaxonomic value, each species having a charateristic chromatographic profile, therefore their analysis is useful in the case of adulterations. The qualitative analysis of flavonoids was performed by TLC and HPLC-MS, mean while the quantitative determination was achieved by spectrophotometric method and individual fractions separated by HPLC-MS.

Published: April 2021

Introduction: The formation of malignant pleural effusion (MPE) is a clinical manifestation of an advanced malignancy or its dissemination. The focus of treatment is primarily palliative and aimed at relieving symptoms, especially dyspnoea.

Material and Methods: Clinical data from patients who were hospitalized at the Clinic of Thoracic Surgery, JFMED CU and Martin University Hospital, in the years 2015–2019 were retrospectively explored and statistically analyzed based on their medical records.

Results: From the group of patients with proven MPE (n=67), 32 patients were male (48%) and 35 were female (52%). The mean age was 62.3 years (65.4 for males and 59.4 for females). The three most common primary malignancies were lung cancer (n=24), breast cancer (n=14), and kidney cancer (n=6). In 38 patients with MPE a talc pleurodesis via VATS was performed, with a median survival of 341 days (95% CI 256–859). Drainage following the talc slurry pleurodesis was performed in 10 patients with a median survival of 91.5 days (95% CI 64-NA). Ten patients with MPE underwent drainage only. The overall median survival time after all types of surgical interventions was 301 days (95% CI 207-389 days).

Conclusion: Management of MPE depends on the patient´s prognosis. A definitive intervention is required in patients with a long-term survival, while in patients with a short life expectancy procedures leading to the shortest hospital stay are preferred. Videothoracoscopic procedures with pleurodesis represent an effective treatment for patients with symptomatic MPE with a good performance status, presence of lung re-expansion following pleural drainage or expected survival.

Published: April 2021

3,4-methylenedioxymetamphetamine (MDMA), also known as “ecstasy”, “tulips”, or “Molly”, is an increasingly used “recreational drug” particularly among teenagers and young adults along with the widespread conviction that MDMA is a “safe drug”. The reason for this substance being abused is a desire for closeness to other people, develop a greater tolerance of their views and feelings, and even to touch them physically. According to these effects MDMA is classified also as an “empatogenic” or “entactogenic”. Although MDMA is used for the above-mentioned socially acceptable purposes, in many individuals the drug usage is followed with side-effects varying from mild to severe, potentially even life-threatening. One of the most significant complication of MDMA intoxication is hyper-thermia in the consumer. Authors presented a case of MDMA toxicity with severe hyperthermia (42 ºC) with a fatal outcome to the ecstasy-influenced subject. The aim of this article is to describe the effects of ecstasy, the “recreational drug” widely used in local pubs, dance clubs, and during open air festivals, even in the Slovak Republic.

Published: April 2021

Yellow dwarf viruses (YDVs) are economically destructive viral diseases of cereal crops, which cause the reduction of yield and quality of grains. Cereal yellow dwarf virus-RPV (CYDV-RPV) is one of the most serious virus species of YDVs. These virus diseases cause epidemics in cereal fields in some periods of the year in Turkey depending on potential reservoir natural hosts that play a significant role in epidemiology. This study was conducted to investigate the presence and prevalence of CYDV-RPV in grasses and volunteer cereal host plants including 33 species from Poaceae, Asteraceae, Juncaceae, Geraniaceae, Cyperaceae, and Rubiaceae families in the Trakya region of Turkey. A total of 584 symptomatic grass and volunteer cereal leaf samples exhibiting yellowing, reddening, irregular necrotic patches and dwarfing symptoms were collected from Trakya and tested by ELISA and RT-PCR methods. The screening tests showed that 55 out of 584 grass samples were infected with CYDV-RPV in grasses from the Poaceae family, while none of the other families had no infection. The incidence of CYDV-RPV was detected at a rate of 9.42%. Transmission experiments using the aphid species Rhopalosiphum padi L. showed that CYDV-RPV was transmitted persistently from symptomatic intact grasses such as Avena sterilis, Lolium perenne and Phleum exratum to barley cv. Barbaros seedlings. PCR products of five Turkish RPV grass isolates were sequenced and compared with eleven known CYDV-RPV isolates in the GenBank⁄ EMBL databases. Compared nucleotide and amino acid sequences of CYDV-RPV isolates showed that the identities ranged from 40.38 − 95.86 % to 14.04 − 93.38%, respectively. In this study, 19 grass species from the Poaceae family and two volunteer cereal host plants were determined as natural reservoir hosts of CYDV-RPV in the cereal growing areas of Turkey.

Published: April 2021

The paper presents the strength evaluation of planetary gear teeth designed for a radial sedimentation tank drive. A novel type of gear drive, composed of a closed epicyclic gear train and an open gear train with internal cycloidal gear mesh is proposed. Contact stress and root stress in the planetary gear train were determined by the finite element method and according to ISO 6336. The influence of the mesh load factor at planet gears on stress values was also established. A comparison of the results followed. It was observed that the mesh load factor on satellites depends mainly on the way the satellites and central wheels are mounted, the positioning accuracy in the carrier and the accuracy of teeth. Subsequently, a material was selected for the particular design of planetary gear and the assumed load. The analysis of the obtained results allowed assuming that in case of gears in class 7 and the rigid mounting of satellites and central wheels, gears should be made of steel for carburizing and hardening. In case of flexible satellites or flexible couplings in the central wheels and gears in class 4, gears can be made of nitriding steel.
Functional Behavior of Pseudoelastic NiTi Alloy Under Variable Amplitude Loading
Authors: Iasnii Volodymyr , Yasniy Petro , Lapusta Yuri , Yasniy Oleg , Dyvdyk Oleksandr
Published: April 2021

Cyclic loading of superelastic NiTi shape memory alloy (SMA) causes forward and reverse austenite–martensіte transformations, and also increases the volume of stabilized martensite. This appears in the change of stress-strain curve form, the decrease of dissipation energy, and increase of residual strain, that is, named transformation ratcheting. In real structures, the SMA components in most cases are under the action of variable amplitude loading. Therefore, it is obvious that the loading history will influence the functional fatigue. In the present work, the effect of stress ratio on the functional properties of superelastic NiTi shape memory alloy under variable amplitude loading sequence with two blocks was investigated. The studies were carried out under the uniaxial tension of cylindrical specimens under load-full unload and load-part unload. The change of residual strain, strain range, dissipation, and cumulative dissipation energy density of NiTi alloy related to load sequences are discussed. Under both stress ratios, the residual strain in NiTi alloy is increased depending on the number of loading cycles on the high loading block that is similar to the tests at constant stress or strain amplitude. An unusual effect of NiTi alloy residual strain reduction with the number cycles is found at a lower block loading. There was revealed the effect of residual strain reduction of NiTi alloy on the number of loading cycles on the lower amplitude block. The amount of decrement of the residual strain during a low loading block is approximately equal to the reversible part of the residual strain due to the stabilized martensite. The decrease of the residual strain during the low loading block is approximately equal to the reversible part of residual strain due to the stabilized martensite. A good correlation of the effective Young’s modulus for both load blocks with residual strain, which is a measure of the volume of irreversible martensite, is observed.

Published: April 2021

With the rapid increase of information generated from all kinds of sources, temporal big data mining in business area has been paid more and more attention recently. A novel data mining algorithm for mining temporal association is proposed. Mining temporal association can not only provide better predictability for customer behaviour but also help organisations with better strategies and marketing decisions. To compare the proposed algorithm, two methods to mine temporal association are presented. One is improved based on a traditional mining algorithm, Apriori. The other is based on an Index-Tree. Moreover, the proposed method is extended to mine temporal association in multi-dimensional space. The experimental results show that the Index-Tree method outperforms the Apriori-modified method in all cases.
Integrated Reporting Performance – Effect of Organizational Behavior Development
Authors: Dănescu Tatiana , Matei Radu Bogdan
Published: April 2021

The effects of the economic crisis and the numerous financial failures of major companies call into question the reliability of financial reporting, which is considered insufficient in reflecting the clear and complete picture of performance, assessed in financial, environmental and social dimensions. In order to obtain an integrate report, it is necessary to combine both financial and non-financial information. Non-financial reporting supports and complements the classic ones, but the complexity of the information provided must also be taken into account, as the phenomenon of opacity may occur, not only due to lack of transparency but also due to difficulty of understanding by users and producer of financial information. Therefore, in the context of long-term global interests, to support sustainable development it becomes important to bring to the research area the identification of the current stage of implementation of integrated reporting with the exemplification of the ranking of sustainability reports of companies listed on the Bucharest Stock Exchange (BSE).

Psychostimulant Subtances Use Among Resident Doctors
Authors: Iacob Diana-Andreea
Published: April 2021

The use of psychostimulants is more and more common lately, especially in the medical guild. The term “burn-out” is an occupational phenomenon, not a disease, and 25-60% of doctors in different specialties have the burn-out syndrome. The method was to complete a questionnaire-type test by 204 medical residents. The results shows us that 72.1% (147) of the respondents drinks coffee, 25.9% of them smokes cigarettes during hospital hours and 13.7% consumes energy drinks. Furthemore 5.9% drinks alcohol during shifts. Among of all, those who are consumers of at least one psychostimulant substance, the risk of them having at least one of the symptoms of burnout is 1.3 times higher than those who do not consume anything at work (RR-1.3453, p = 0.0152). Psychostimulant substances are consumed to improve the efficiency and resistance at work. It’s important to manage the time in order to avoid extreme fatigue and distress.

Authors: Luchian Mihaela , Săceleanu Adriana
Published: April 2021

A haemorrhagic cerebrovascular accident refers to a spontaneous bleeding in the cerebral parenchyma, located either supratentorial or infratentorial, that occurs in the absence of a surgical or traumatic cause. The incidence is estimated at 12-15 new cases per 100.000 inhabitants per year. Intracranial haemorrhage is the third most frequent cause of stroke, the vast majority being represented by primary/hypertensive (spontaneous) intracerebral haemorrhage, ruptured saccular aneurysm, a vascular malformation or haemorrhage associated with the use of anticoagulants or thrombolytic agents. A cerebral tomography computer examination is the examination of choice in diagnosis of haemorrhagic CVAs. The treatment can be either therapeutic or surgical, depending on the case, with the consideration that an immediate medical treatment is mandatory for the best odds of recovery.(1)

Published: April 2021

Orbital pseudotumor represents a benign inflammatory disorder of the orbit, with unspecified etiology, whose clinical presentation can mimic the ocular pathology of Basedow disease, namely Graves’ ophthalmopathy, the two of them representing two of the most common orbital conditions. Imagistic methods and laboratory analyses can establish the diagnosis through orbital MRI images specific for the orbital pseudotumor, especially by dosage of the TSH receptor antibodies (TRAb) which will have increased values in Basedow disease with ocular damage. In both situations, the treatment is represented as a first therapeutic line by administration of corticotherapy in high dosage orally or intravenously, with favorably evolution, which is also observable in the case of our patient who was diagnosed with orbital pseudotumor based on MRI images, with associated thyroid dysfunction with negative TRAb, in which the pulse therapy with Solumedrol has determined the improvement of ocular symptoms and signs.

Being considered a rare form of malignant neoplasm, stromal tumours are part of sarcomas group, they account for ~5% of all sarcomas (1), which develop from the supporting tissues of the body and have as a starting point special cells located in the wall of the gastrointestinal tract, called interstitial cells - described by Cajal. Although this type of tumour formations poses the problem of diagnosis, when it is made early and surgical and oncological treatment is prompt, the prognosis improves considerably.

Numerous studies in the last decades report a frequent association of marginal periodontal disease with some systemic metabolic disorders, such as diabetes or obesity. The prevalence of these diseases is growing alarmingly both globally and in our country. Recent data from the literature confirm that advanced forms of periodontal disease can influence the evolution of type 2 diabetes. This may provide a premise for better glycemic control.

The main objective of the study was to determine the effect of transition from a conventional milking system (CMS) to an automatic milking system (AMS) on survival of 6361 Polish Holstein-Friesian cows to second (SL2), third (SL3) and fourth (SL4) lactation as well culling reasons. The cows were born between 2002 and 2015 and calved between 2004 and 2018. All data for the survival analysis and culling reasons of cows in 17 herds during operation of CMS and AMS were extracted from the SYMLEK official milk recording system. Cow survival (SL2, SL3 and SL4) was analysed with multiple logistic regression using the following effects in the model: milking system (MS), first calving season (CS), age at first calving (AFC), ease of first calving (CE), birth of a dead calf at first calving (DC), milk yield (MY) for full first lactation (MY – this effect was ignored in SL2 analysis), herd (H), and MS × H interaction. In the next stage of the study, χ2 test was used to analyse culling reasons of cows (udder diseases, low fertility – infertility and reproductive disorders, locomotor diseases, low milk yield, other diseases – metabolic, digestive and respiratory diseases, accidents and chance events) in the first, second and third lactation and collectively in the first three lactations. Logistic regression analysis indicated a significant effect of MS, AFC, DC on SL2 and SL3, and of MY on SL3 and SL4. Moreover, H and MS × H interaction had a highly significant effect on SL2, SL3, and SL4. Cows used in AMS barns were characterized by significantly worse SL2 and SL3 compared to CMS (odds ratio), by 27.8% and 31.0%, respectively. It was also observed that the effect of switching from CMS to AMS on cow survival was determined by herd membership – in most herds this effect was unfavourable. A distinctly positive effect of milking automation on cow survival (SL2, SL3, SL4) was noted in only one barn (herd) – it was a new barn with a considerably expanded number of milked cows, where the lying area was covered with straw. When analysing the reasons for culling in the first three lactations collectively, it was found that after the AMS system was introduced into the herds, there were increases in the rate of culling for locomotor diseases (by 0.85 percentage points (p.p.)), low milk yield (1.36 p.p.) and other diseases (3.01 p.p.). It was also observed that the automation of milking reduced culling due to udder diseases by 0.37 p.p., low fertility by 3.24 p.p., and accidents and chance events by 1.60 p.p.

The objective of the present study was to analyze the morphometric variations of the three presumed taxa within the Barbonymus group, namely B. gonionotus, referred to locally as naleh; B. schwanenfeldii, referred to locally as lampam-A; and Barbonymus sp. referred to locally as lampam-B. The naleh samples were collected from Nagan Raya District, while lampam-A and lampam-B were collected from Aceh Tamiang District, Indonesia. Traditional morphometric characters were measured in 150 fish samples (50 individuals of every taxon). The results of univariate (ANOVA) and multivariate (Discriminant function analysis, DFA) analyses showed that lampam-A and lampam-B have overlapping morphological characteristics, whereas naleh were distinctly different. Therefore, it is presumed that lampan A and lampan B are the same species of B. schwanenfeldii. It was concluded that the morphometric data indicated that there are two species of Barbonymus in Aceh waters, i.e., B. schwanenfeldii and B. gonionotus.

The aim of the study was to compare the quality and quantity parameters of semen in male lake minnow, Eupallasella percnurus (Pallas, 1814), from six Polish populations. Substantial differences among the populations were found in milt volume (36–112 µl) and sperm concentration (4.7–8.0 × 109 ml−1). Mean values for sperm motility were similar; however, there were population-related differences in sperm velocity measured with VSL (96.3–127 µm s−1). Despite this, the quality of semen in all cases was high and appropriate for both artificial reproduction and cryopreservation.
Optimization of SPE method for the extraction of 12 neurotransmitters from sheep brain

Published: April 2021

The present paper presents our attempts concerning the development of an extraction method for catecholamines. In order to achieve the extraction of all the selected solutes using a single SPE cartridge, several types of support were tested, among them: cation exchange supports, hydrophilic-lipophilic supports, C18 supports and PGC supports. As unfortunately none of the supports tested offered us the possibility of carrying out the extraction of 12 catecholamines from our standard mixture, we chose to use a coupling of two different cartridges: Oasis HLB and PGC which together ensure the extraction of all the compounds of the mixture with good extraction yields and with simple protocols. The selected cartridges were successfully tested for the extraction of a sample spiked from sheep brain with the 12 catecholamines in our mixture. The SPE method that we have developed allows the purification of the samples (a significant part of the components of the matrix is eliminated during this step) and also a preconcentration of the samples.
Experimental Harmonization of Shape Intuitive Interaction
Authors: Žukas Jonas
Published: April 2021

With the increasing functionality and complexity of the material environment it is becoming important to universally improve the quality of its shape design for people with different knowledge. When the material environment shape does not match its value content or acquire unpredictable meaning, it creates disharmony between the function and user that requires intellectual and / or emotional effort for interaction. The intuitive design improves user’s interaction because the information is presented on the subconscious level, hence it is accepted as a natural part of our environment and demands less effort to grasp and evaluate it. In this study, the scientific context of intuition is examined to determine methods and values of shape intuitive expression modeling. The goal of the study is to assess the effectiveness of shape experimental intuitive harmonization methodology using qualitative and quantitative methods. Functional and interaction restrictions are integrated into the object’s shape by employing experimental modeling techniques. Surveys, controlled observations and MaxDiff analysis were used to monitor intuitive harmonization effects on car body split-line and box shape physical models. Experimental results show that the majority of participants consider conceptual shape models to be more intuitively attractive and informative. The study concludes that it is possible and viable to employ a proposed shape intuitive harmonization variable to achieve a universally positive effect.
From Construction to Deconstruction. The Heritage of Post-War Modern Mass Housing
Authors: Belli Nicola
Published: April 2021

The aim of the study is to find out to what extent dominant ideologies of post-war decades shaped modern mass housing and to engage a discussion about potential heritage of the phenomenon. Analysis is based on the district of Lazdynai (Vilnius). The paper is committed to demonstrate that transition, considered by Tunbridge & Ashworth as a factor of dissonance in heritage, made messages and meanings embedded in mass housing obsolete, and in some cases even undesirable.
Designing Legitimate Institutions for Non-Territorial Autonomies. Insights from the Debates within the Hungarian Communities of Serbia and Romania
Authors: Székely István Gergő
Published: April 2021

In this paper, I examine some problematic aspects of minority self-governments, more specifically non-territorial cultural or national-cultural autonomy, through an analysis of the cases of the Hungarian minorities in Romania and Serbia. Although the Hungarian minority élites have put forward demands and plans for various forms of autonomy in both countries after 1990, only one particular form of minority self-government, namely national-cultural autonomy, proved to be acceptable for the majority, and eventually such a system was only implemented in Serbia but not in Romania. The focus in the article is more on the form than on the content of autonomy as the design of the institutions of self-government is of central importance also with regard to the power relations within the imagined political community of the minority. Despite the differences between the legal-institutional systems of minority protection of the two states, the patterns of minority élite behaviour were rather similar in the two analysed cases, the institutional form of the envisaged autonomy becoming a very divisive issue and exerting a strong impact on the internal political dynamics of the minorities.
Turkish Great Chess and Chinese Whispers: Misadventures of a Chess Variant
Authors: Markov Georgi , Härtel Stefan
Published: April 2021

A large chess variant with 52 pieces originally described in a 1800s Ottoman Turkish book as šaṭranǧ-i kabīr, or great chess, appears under various names in a number of subsequent Western sources, including authoritative works on chess history and variants. Game rules as presented in the latter are seriously flawed though, with inaccuracies regarding pieces array and moves. Over a period of more than two centuries, baseless assumptions, misreadings of previous sources and outright errors gradually accumulating in the literature have changed the game almost beyond recognition. With some of the game’s aspects not covered even by the original Turkish source, reconstructed rules are suggested and discussed, as well as a reformed variant.
