Factors Affecting Employees' Susceptibility to Cyber-Attacks
Authors: Boritz J. Efrim , Ge Chan (Jessie) , Patterson Katharine
Published: July 2022

We examine factors associated with employees' susceptibility to phishing attacks in a professional services firm and a financial services firm (bank). We measure three dimensions of suspicion (skepticism, suspicion of hostility, and interpersonal trust), and three cognitive traits (risk-taking propensity, cognitive [inhibitory] control, and social cognition), while controlling for demographic and work context factors. We find that these traits interact in complex ways in determining individuals' susceptibility to phishing attacks. Bank employees are more susceptible to being phished than professional services firm employees, but within the bank, the employees with professional certificates are less susceptible to phishing attacks than other bank employees. Also, employees with self-reported responsibility for cybersecurity are less likely to be phished. These findings could be used to create a screening tool for identifying which employees are particularly susceptible to phishing attacks, to tailor training, or redesign jobs to counter those susceptibilities and reduce security risk.

Chronic, non-healing skin wounds such as diabetic foot ulcers (DFUs) are common in patients with type 2 diabetes. Here, we investigated the role of chemokine CCL28 and its receptor CCR10 in downregulation of endothelial nitric oxide synthase (eNOS) in association with delayed skin wound healing in the db/db mouse model of type 2 diabetes. We observed reduced eNOS expression and elevated CCL28/CCR10 levels in dorsal skin of db/db mice and subdermal leg biopsies from human subjects with type 2 diabetes. Further interrogation revealed that overexpression of CCR10 reduced eNOS expression, NO bioavailability, and tube formation of human dermal microvascular endothelial cells (HDMVECs) in vitro which was recapitulated in mouse dorsal skin. In addition, incubation of HDMVECs with CCL28 led to internalization of the CCR10/eNOS complex and co-localization with lysosome-associated membrane protein-1. Finally, topical application of myristoylated CCR10 binding domain 7 amino acid (Myr-CBD7) peptide prevented CCR10-eNOS interaction and subsequent eNOS downregulation, enhanced eNOS/NO levels, eNOS/VEGF-R2+ microvessel density, and blood perfusion, reduced inflammatory cytokine levels, and importantly, decreased wound healing time in db/db mice. Thus, endothelial cell CCR10 activation in genetically obese mice with type 2 diabetes promotes eNOS depletion and endothelial dysfunction, and targeted disruption of CCR10/eNOS interaction improves wound healing.

Published: July 2022

The manufacturing of battery packs plays an essential role in e-mobility. In this context, laser welding of batteries has taken a considerable momentum in recent years as it can quickly adapt to different form factors and battery arrangements which is crucial for short runs and on-demand manufacturing. In this paper, we present an assisted battery pack welding system applying a novel sensor fusion strategy. The presented work introduces a multi-camera solution combining a camera in the visual range and an infrared camera in a compact scanner head that applies graphics processing unit acceleration for image processing and real-time field programmable gate array processing for process control. In order to acquire accurate temperature measurements, the infrared camera has been characterized and calibrated for the temperature ranges of the welding process. In addition, we propose a method for image space coordinate transformation based on affine transformations used to transform the coordinates of the detected battery joints into different image spaces to adapt to the welding process in real time. A single shot multibox detector Mobilenet-v2 neural network has been retrained with custom images to detect and classify a set of battery pack types allowing the extraction of the battery cell joint coordinates using image processing, which enables the application of real-time corrections to the laser aiming system and a closed-loop laser power control. Finally, we present some battery welding results using different welding strategies on the described system.

RELAÇÕES DE GÊNERO E EDUCAÇÃO: as imagens dos livros didáticos reforçam ou desconstroem os estereótipos de gênero?
Authors: Peres Gonçalves Josiane , De Oliveira Rocha Luana
Published: July 2022

Este artigo se refere a um estudo acerca dos estereótipos de gênero expostos nas imagens dos livros didáticos utilizados pelo 5° ano do ensino fundamental de uma escola estadual de Mato Grosso do Sul. Teve por objetivo analisar se as imagens dos livros didáticos contribuem para reforçar ou desconstruir os estereótipos de gênero predominantes na sociedade. A pesquisa documental foi realizada a partir da análise das imagens existentes em três livros didáticos, das áreas de Ciências, História e Geografia. Assim, foram encontradas imagens de homens lavando louça e limpando a casa, imagens de meninas brincando de futebol e skate, além de imagens críticas acerca da sobrecarga de trabalho realizada pelas mulheres ou sobre o trabalho das empregadas domésticas, que somente em 2013 tiveram os seus direitos trabalhistas reconhecidos. Nos três livros didáticos analisados, não foram encontradas imagens que reforçassem claramente os estereótipos de gênero, pois embora tenha sido encontrada a imagem de uma menina brincando de boneca, o texto dizia que ela também brincava de futebol e em outro momento apresentava a imagem de uma menina jogando bola. A partir do estudo realizado, foi possível notar que há avanços e tentativas de desconstrução de estereótipos de gênero, nas imagens existentes nos livros didáticos. Deste modo, o trabalho de adequar os livros didáticos, a fim de contribuir com a desconstrução dos estereótipos de gênero, é relevante e necessário, por se tratar de um tipo de material que os alunos de escolas públicas mais utilizam em seu processo de aprendizagem.

É por meio da língua que os seres humanos se relacionam das mais diversas formas. A linguagem acontece viabilizada pela singularidade de cada pessoa nas relações que são estabelecidas nas mais diversas situações enunciativo-discursivas, e que motivam a construção da comunicação. Para Bakhtin (2006, p. 295), “o diálogo, por sua clareza e simplicidade, é a forma clássica da comunicação verbal”. Dessa forma, é no interior das relações entre os sujeitos sociais e, portanto, por meio da linguagem, que os sujeitos compreendem e são compreendidos por seus pares exercendo, mutuamente, seus papeis em diferentes fenômenos e eventos de interlocução.

This study investigates the mechanisms underlying the relationship between intrateam learning behaviors and team performance in student project teams in terms of contribution conflict as an antecedent of the team shared mental model on team tasks. The data collected from a sample of 201 Romanian student teams show that only team shared mental model on team tasks totally mediates the relationship between intrateam learning behaviors and team performance. Moreover, contribution conflict and team shared mental model on team tasks taken together fully mediate the relationship between intrateam learning behaviors and team performance. We conclude our study by suggesting future research on the main topic of team learning and team effectiveness.
Associations between digital amnesia, sleep disorders and somatic symptoms among youth
Authors:   Department of Psychology, Periyar University, Salem, India, Savarimuthu James Robert , Subramanian Kadhiravan ,   Department of Psychology, Periyar University, Salem, India
Published: July 2022

Digitalization has accelerated and improved the accuracy of information processing. It has changed society into a connected world. The spread of COVID-19 changed individuals' daily routines drastically over the past two years, especially among youth due to the temporary closure of colleges and universities. The usage of digital devices by youth has increased as a result of online learning platforms, leading to digital reliance and a negative impact on their sleep quality. Therefore, this study aimed to investigate (1) the association between digital amnesia, sleep disorders and somatic symptoms, (2) the difference in digital amnesia based on the demographic categories, (3) the effect of digital amnesia and sleep disorders on somatic symptoms. A cross-sectional study was conducted on 326 young people aged 18 to 25 years. Data was collected from participants using the Digital Amnesia Scale, Sleep Disorders Symptom Checklist (SDS-CL-17), and Somatic Symptom Disorder-B Criteria Scale (SSD-12). There was a significant association between digital amnesia, sleep disorders, and somatic symptoms among youth. Youth differed significantly in their digital amnesia based on their demographic categories such as gender and family type. Somatic symptoms among youth were significantly impacted by digital amnesia and sleep disorders. Youth could overcome their digital amnesia by utilizing digital devices effectively. Youth could also be sensitized about adverse effects of digital amnesia. Taking a digital break could help them improve their quality of sleep and reduce somatic symptoms.
World-Literature and the Bessarabian Literary System. Combined and Uneven Development in The Semiperiphery
Authors:   Babes-Bolyai University, Bâlici Mihnea
Published: July 2022

This essay proposes a theory of interperipheral relations in Eastern Europe, starting from the cases of Romania and the Republic of Moldova. The aim is to affirm a more materialistic interpretation of world-literature studies, starting from the thesis of separation and inequality between the two Romanian-language literary systems. Thus, the essay starts from a critique of several directions of world literature and postcolonialism, returning to the method of world-systems analysis (as conceived by Immanuel Wallerstein and his followers). Another method is that of the Warwick Research Collective, which conceives global literature as defined by the Marxist theory of combined and uneven development. Romania, being in a geopolitical position that is closer to the neoliberal ideologies of “civilizational progress” and “artistic modernity”, represents Moldova's access point to the transnational market. The cases exemplified in the second part of the essay highlight the way in which a series of Bessarabian authors use and recontextualize some narrative forms specific to post-communist Romanian literature. The authors brought into discussion are the Fracturists Dumitru Crudu and Alexandru Vakulovski, the journalist Vasile Ernu, the anthropologist Dinu Guțu, the Bessarabian novelists Iulian Ciocan and Liliana Corobca, and the émigré writer Tatiana Țîbuleac.
From Capitalist Aspirations to the National Project. The Inter-Imperial Transylvanian Compromise
Authors:   Lucian Blaga University of Sibiu, Olaru Ovio
Published: July 2022

In the present article, I address two novelistic productions set in late 19th century and early 20th century Transylvania, discussing the different intersections of class, ethnicity, and culture underlying the constructed image of Empire in the periphery. Drawing on Manuela Boatcă and Anca Pârvulescu’s work on Transylvanian inter-imperiality – borrowed, in turn, from Laura Doyle –, the paper discusses Ioan Slavici’s Mara and Liviu Rebreanu’s Forest of the Hanged as stages of imperial downfall. The main argument is that, whereas Mara and other similar works present the interclass and interethnic conflict as negotiable compromise functioning as narrative momentum for the novelistic plot, the compromise comes undone in Forest of the Hanged, where the capitalist aspirations of the former work is put aside in the forging of national identity.
The Rhizomatic: A Spatial Form in Contemporary Romanian Poetry
Authors:   Babes-Bolyai University, Conkan Marius
Published: July 2022

Using geocritical methods and exploring the spatiality of texts, this study aims to demonstrate that the rhizomatic, the well-known Deleuzian concept, constitutes one of the spatial forms in contemporary Romanian poetry. In this sense, rhizomatic poetics transgress unitary semantics through interferences, disorders and (constantly rearranged) connections of forms and images to ultimately signal new perceptions of reality. As global meanings are pulverized, within some networks that capitalize mainly on the trace and the semantic transgressivity, these poetics end up generating a continuous reassembly of real elements, akin to a system which, through juxtaposition, multiplicity and nomadism, creates its own formal and affective space.
Misfits and Troubled Men. Masculinity and Violence in Romanian Socialist Cinema
Authors:   Babes-Bolyai University, Pojoga Mădălina
Published: July 2022

This paper is part of an ongoing research project that aims at identifying types of masculinities in Romanian socialist cinema, by using gender studies and other contributions on the topic of masculinity in order to provide a sociological reading of Romanian films made during the communist regime. I will look at the way in which Western understandings of masculinity have been transferred to Eastern European categories of masculinity in cinema and I will establish a critical framework for my analysis, with an introduction to studies on masculinity, and expand on elements of sociological and psychoanalytical works, namely major contributions from Connell (1987), Segal (2007) and Horrocks (1994, 1995). Two defining concepts in masculinity studies are hegemonic masculinity (Connell 1987) and homosociality (Bird, 1996), theories which will constitute the basis for my case studies in order to see if male characters in Romanian socialist cinema fit into this categorization. The last part of this paper will be an analysis of three films, Reenactment (Reconstituirea, Lucian Pintilie, 1968), 100 Lei (100 de lei, Mircea Săucan, 1973) and At the End of the Line (La capătul liniei, Dinu Tănase), in which the male characters exist outside society, they cannot conform to what is being required of them as socialist subjects. The purpose is to see how gender performativity plays a role in the relationship between men, with a focus on violence and how it is connected to a search for a father figure and male friendships.
Compensation and Kin Selection in the Long Nineteenth Century Translationscapes
Authors:   Lucian Blaga University of Sibiu, Baghiu Ștefan , Modoc Emanuel ,   Romanian Academy
Published: July 2022

Using network models and quantitative methods, the present article provides a bird’s-eye-view of the Romanian novelistic translationscape published in volumes during the “long 19th century”. The study approaches the cultural production of translated novels in the selected period from a relational perspective, aiming to investigate the connections between different publishers, with their respective editorial practices, and the translated authors selected from both major and minor source cultures. With this in mind, our paper will attempt not only to analyze the actor-network aspect of the translational networks established in the country, but also to provide an interpretive model for the selection of specific translated authors over others and their role in the cultural and nation-building process of early-modern Romanian culture.
The Discrepancy between Microchip Production and Automotive Industry born in Covid Pandemic Period 2019-2022
Authors: Hristova-Politikova Maria Cvetanova
Published: July 2022

During the Covid-19 pandemic period the tiny particles - the microchips proved to be in high demand by various industries – from IT to the production of simple consumer goods. Main objective of this analysis is to explain the reasons for the shortage of chips and semi-conductors for the automotive industry as the auto maker resumed their activities after the lock downs. Haltering of orders by the major auto producer and rerouting of chip production towards supplies for the electronic industry which proved willing to pay more are the main reasons. Trade specialization and globalization which are endemic for the contemporary world economy do not help to restore the broken supply-demand equilibrium of microchips.

Service Encounters and Guests Patronage of Hotels
Authors: EWANLEN Donald O. , Ewanlen Donald E.
Published: July 2022

In service oriented businesses, interactions between service providers and customers are inevitable. These interactions create impressions in the minds of the parties which to some extent define patronage outcome. For a meaningful outcome, an understanding of the creators of satisfactory patronage is germane. This study investigates the influence of customers’ encounters in defining the outcome of hotel patronage. This study adopted a cross-sectional design using a structured questionnaire survey of guests of 3 star and above rated hotels in Yenagoa, Bayelsa state Nigeria .Four hundred copies of questionnaire were distributed in ten strategically selected hotels, and 290 copies were found useful. This represents about 73% response rate . The SPSS 23.0 statistical software package were used for data analysis. Multiple regression analysis and Pearson correlation was employed to test the formulated hypotheses at 5% significance level. This study reports that youth are in majority of hotel patrons. Empirical analysis further reveals that all the dimensions of service encounters reports a significant relationship with word- of- mouth recommendations. Furthermore, the regression analysis reveals that peace of mind, moment of truth, outcome focus and product experience could explain about 53% variation in patronage outcome. The paper conclude that all the dimensions of customer experience has a significant influence on word- of- mouth recommendations of guests. This paper recommend among others things the training and retraining of service personnel. This training should equip frontline employees with the requisite skills that would enable them create and manage pleasurable experiences.

Authors: Clark William A. , Winter Randolph L. , Aarnes Turi K. , Green Eric M. , Mikrut Katarzyna , Ruz Patrick , Addison Daniel , Rhinehart Jaylyn D. , Schober Karsten E. , Friel Harry T.
Published: July 2022

OBJECTIVE

To assess whether cardiac MRI or various biomarkers can be used to detect myocardial ischemia and fibrosis in dogs with cardiomegaly secondary to myxomatous mitral valve disease (MMVD).

ANIMALS

6 dogs with cardiomegaly secondary to naturally occurring stage B2 MMVD being treated only with pimobendan with or without enalapril and 6 control dogs with no cardiac disease. All dogs were ≥ 5 years old with no systemic illness.

PROCEDURES

Serum cardiac troponin I and concentrations were measured, and dogs were anesthetized for cardiac MRI with ECG-triggered acquisition of native T1- and T2-weighted images. Gadolinium contrast was administered to evaluate myocardial perfusion and late gadolinium enhancement (LGE). Mean T1 and T2 values and regions of LGE were measured with dedicated software. Extracellular volume (ECV) was estimated on the basis of Hct and T1 values of myocardium and surrounding blood. Subjective analysis for myocardial perfusion deficits was performed.

RESULTS

Dogs with MMVD had significantly (P = .013) higher cardiac troponin I concentrations than control dogs, but galectin-3 concentrations did not differ (P = .08) between groups. Myocardial fibrosis was detected in 4 dogs with MMVD and 3 control dogs; no dogs had obvious myocardial perfusion deficits. Native T1 and T2 values, postcontrast T1 values, and ECV values were not significantly different between groups (all P > .3).

CLINICAL RELEVANCE

Results suggest that some dogs with cardiomegaly secondary to MMVD may not have clinically relevant myocardial fibrosis.
Small animal general practitioners discuss nutrition infrequently despite assertion of indication, citing barriers
Authors: Alvarez Elizabeth E. , Schultz Kelly K. , Floerchinger Amanda M. , Hull Jennifer L.
Published: July 2022

OBJECTIVE

To determine what perceived factors prevent small animal general practitioners from discussing pet nutrition with clients during healthy and sick pet appointments.

SAMPLE

403 veterinarians in small animal general practice.

PROCEDURES

An online survey was used to gather veterinarians’ opinions on perceived barriers, knowledge levels, and confidence regarding pet nutrition discussions.

RESULTS

Reported barriers to discussing nutrition during healthy pet appointments included client resistance to changing brand (149/359), time constraints (146/359), misinformation online (138/359), and difficulty keeping up with products (132/359). Reported barriers to discussing nutrition during sick pet appointments included client cost concerns (101/349), pet not accepting new food (99/349), and time constraints (83/349). Veterinarians reported discussing nutrition less during healthy pet appointments, compared to sick pet appointments, and were significantly less confident with their knowledge regarding nontherapeutic food, compared to therapeutic food. Veterinarians also reported that they perceived conversations about therapeutic foods to be more positive than conversations about nontherapeutic foods, and veterinarians with more years in practice more commonly reported that there was nothing that would dissuade them from discussing nutrition. Veterinarians who reported barriers to discussing nutrition described a need for resources and reliable information for health-care teams and clients.

CLINICAL RELEVANCE

Results demonstrated a substantial gap between veterinarians’ assertion that nutrition conversations are indicated and the frequency with which they discuss nutrition during appointments. Veterinarians reported that they felt their nutrition conversations were frequently positive; therefore, it is important to overcome barriers to engage with clients about pet nutrition.
Mathematical Modeling Thoughts and Methods Based on Fractional Differential Equations in Teaching
Authors: Chen Yingwei , Chang Zhikui , Mohamed Hamdy
Published: July 2022

This article combines ordinary differential equations’ theoretical and practical characteristics to explore how to integrate mathematical modeling ideas in teaching materials and teaching methods. We apply the fractional differential equation algorithm to the mathematical modeling of Terman diffusion. At the same time, the article proposes a framework for obtaining accurate solutions of a class of nonlinear Sinai stochastic models with power-law diffusion through Mittag-Leffler function transformation. In this way, we have obtained great explicit and accurate solutions of some important Mittag-Leffler function power-law diffusion physical processes.
The Uniqueness of Solutions of Fractional Differential Equations in University Mathematics Teaching Based on the Principle of Compression Mapping

Published: July 2022

This paper uses the principle of compressed mapping to discuss the existence and uniqueness of the explicit finite difference method for the fractional diffusion equation with time delay. The Laplace transform method obtains the necessary expression form of the solution. At the same time, the existence theorem and the existence and uniqueness theorem of the solution to the boundary value problem is established. Finally, an example is given to verify the correctness of the conclusion. The experimental results show that the parallel algorithm proposed in this paper agrees with the exact solution.
Didactic model of the “Chemistry training process” system when applying semiotic approaches
Authors: Vasileva-Tcankova Radostina Strahilova
Published: July 2022

The present development uses the modeling method described in the literature and proposed a new didactic, functional model of the “chemistry training” system in the application of semiotic approaches: semantic, pragmatic, and syntactic. The main objective of creating such a model is to demonstrate the specific activities of the subjects “teacher” and “pupil” when familiarizing themselves with chemical symbols and their study by students. The added new components in the model “Technology of chemistry training”, “Semiotic information” and the clarified links between them, lead to a complete change in the way the described system works. The developed didactic model makes it easy to guess the relationship between a new learning situation and a result, that is, to predict an unknown process or phenomenon. This model makes it possible to formulate a reasoned hypothesis of the study.
Experimental study on the impact of semiotic approaches on students’ knowledge of chemical symbolism in seventh and eighth grade
Authors: Vasileva-Tcankova Radostina Strahilova
Published: July 2022

Experimental work in its milestones is carried out according to the following algorithm:

1. Development of a methodological system, including additional training content in Chemistry and Environmental Protection for the seventh and eighth grades /purposefully selected urological fragments, exercises and summary lessons/, in which the subject of study is chemical symbolism, with the application of semiotic approaches - semantic, pragmatic and syntactic.

2. Conducting a pedagogical experiment to establish the effectiveness of the developed methodological system.

3. Analysis of the results of the pedagogical experiment.

The pedagogical experiment is included in the work as the main method of researching the influence of semiotic approaches on the knowledge and skills of students for the proper use of chemical symbols. By conducting a pedagogical experiment, it has been shown that the use of the three semiotic approaches in Chemistry and environmental training facilitates and improves the understanding of the complex meaning of chemical symbols by students. The analysis of the results of the written control works in the seventh and eighth grades shows the existence of significant qualitative differences in students’ knowledge of how to identify chemical objects and the degree of skills formed to reveal the information embedded in chemical symbols.
Global Ecological Problems of Modern Society
Authors: Vasileva-Tcankova Radostina Strahilova
Published: July 2022

At the modern stage of society’s development, ecology is seen as a complex, interdisciplinary science of the relationships of organisms, society and the environment. Ecology is a science that studies the regularities of the life of organisms in their natural living environment and taking into account the changes made in this environment as a result of human activity. In recent years, the mass media has been constantly talking and writing about ecology, environmental problems related to anthropogenic activity. The person with his activity is heavily polluted and continues to negatively affect the environment at increasing rates. This reckless behavior of humans and the whole of society threatens planet Earth with imminent doom, no less than the use of nuclear weapons. Only from the positions of modern science ecology is it possible to develop issues related to the prudent use of the natural resources of the biosphere and the fight against changes brought about in nature by human activity in the age of the scientific and technical revolution. For this reason, it is necessary to seek information and a solution to the key current problems: What are the main pollutants of the atmosphere, hydrosphere and lithosphere? What is the origin of these substances? How does their impact affect life on Earth? What approaches and methods are needed to prevent environmental pollution?

Published: July 2022

The efficiency of pineapple crown extract as corrosion inhibitor of aluminum in 1M H2SO4 acidic medium was tested using weight loss and potentiodynamic methods, at varied inhibitor concentration. Through the data from the weight loss method there was calculated the corrosion rate and pineapple crown extract’s inhibition on aluminum corrosion in acidic medium, at varied inhibitor concentration. Also, with the data obtained from the potentiodynamic method, the polarization curves and Tafel tangents were constructed, while calculating the corrosion rate and inhibition efficiency of pineapple crown extract. Experimental measurements showed that pineapple crown extract acts as a mixed inhibitor and the inhibition efficiency increases with increasing the extract concentration.

Published: July 2022

Box girders bridges are widely used in modern highway systems because of their efficiency and attractive appearance. Vehicles loads represent one of the mainly factors that influence the structure reliability of the box girders bridges. Calculation of bridge resistance with different stress due to vehicles loads as close as possible to the real ones constitute the premise of a correct design of the structure. The goal of this study is to realize a description regarding the behavior of box girders bridges analyzed under different vehicles loads conditions. Nowadays the finite element methods (FEM) are highly used because of their capacity to simulate and evaluate the structure efficiency of bridges. By highlighting where the maximum stress values appear we will help the constructor to avoid dangerous sections. Based on this study, we will outline future research directions, aiming to identify and improve the mechanical and strength characteristics of box girders bridges.
Design Solutions for Large Size Ball Valves

Published: July 2022

Development of sustainable cities requires safe and efficient pipeline networks for the transportation of fluids. Ball valves are usually used to start/stop the flow of liquids or gases in pipelines, because they generate low hydraulic losses when the valve is in fully open position and no leakage in fully closed position. They are highly recommended, when quick operation is needed in emergency situations. European Union and United States of America have implemented stringent laws to regulate the standards of small and medium size pipeline components. Design parameters may require large size valves that are not in the focus of the present standards and in this case, individual solutions are needed.

In this work, a methodology to design ball valves that are not in the standardized series is step by step presented. The case study of a Trunnion ball valve with a 900 mm bore diameter is discussed. The standard API 6D/ ISO 14313 recommends design methods for valves with face-to-face dimension between flanges for diameters up to DN900, therefore the proposed methodology is original.
A Review on Treating Tribological Problems with Fractals
Authors: Lăpuşteanu Alexandru , Paleu Viorel
Published: July 2022

Fractals and chaos theory provide means of modeling dynamic changes in micro and nano topography on friction surfaces caused by various tribological mechanisms and processes. Friction and wear phenomena in tribological systems can be interpreted on a macroscopic scale. With the development of miniaturized scale and nanoscale systems, it has been launched the hypothesis that macro-level systems cannot reflect the microscale and nanoscale phenomena. A conclusive case is given by the calculation of frictional torque in microscale orientation, in this situation being found that models created by bearing producers cannot validate experimental results. By applying the “box-counting” method, it is possible to estimate the fractal dimension both directly and indirectly by comparing the area-perimeter-scale relations. Based on scaling equations, a system was created for this operation. The conclusion is that all existing theories in tribology should be adapted to take into account fractal size and fractal roughness.
Considerations on Classification of the Main Components of the Vehicles By their Vibroacoustic Fingerprint
Authors: Niţu Nicolae-Adrian , Bujoreanu Carmen
Published: July 2022

The modern car industry is evolving under new premises, such as new propulsion technology, which imply offering to the customer the completed new solutions (charging station, service contract and remote diagnosis). Proven diagnostic technology is reaching its limits because is generally based on detecting the electrical faults and the mechanical, hydraulic and pneumatic failures have a slight degree of detection by this method. An alternative method of diagnosis could be the study of actual noise and vibration parameters of the main components of the vehicle subject to major faults and compare them to that specific to good status of operation. This paper deals with the classification of the main components of the vehicles by their vibroacoustic fingerprint. Those components of the vehicle grouped by vehicle category and their common patterns of vibroacoustic fingerprints must be permanently overseen and compare with those assigned to the status of good health for diagnosis.

Published: July 2022

The RF9 compound, which is an antagonist of the FF neuropeptide receptors is used as a therapeutic substance to improve the effectiveness of opioids in the chronic treatment of pain. The purpose of this study was to find the most efficient method of RF9 synthesis. The optimization experiment involved solid-phase peptide synthesis. The Fmoc strategy is based on the usage of the 9-fluorenylmethoxycarbonyl group to block reactive amino groups. Commonly applied RF9 synthesis is based on DIC/HOBt activation of 1-adamantanecarboxylic acid prior to its substitution. The experiments carried out in this research were based on the routinely applied DIC/HOBt carboxylic group activation and this scheme was compared with the COMU/DIPEA and DIC approach. The obtained results showed that COMU/DIPEA was the most efficient and effective method of RF9 synthesis. Using this strategy, pure compound was obtained, without any by-products, and at a highest yield. The use of COMU/DIPEA can be an excellent alternative to the routinely used RF9 synthesis.
The recent guidelines for pharmacotherapy of Parkinson’s Disease

Published: July 2022

Parkinson’s Disease (PD) is one of the most frequent disorders of the central nervous system (CNS). PD is an age-related disease in that morbidity increases with age. The main symptoms of it are motor symptoms like bradykinesia, rigidity and resting tremor. These symptoms diminish the comfort of the patient’s life and may lead to immobility. Hence, rapid diagnosis and start of treatment are very important.

The pharmacotherapy of PD is difficult. PD involves an imbalance between the dopaminergic and cholinergic systems. Therefore, the mechanisms of action of currently available drugs are highly connected with the pathology of PD, and follow dopaminergic or anticholinergic control strategies. However, long-term use of many PD medications comes with serious side effects. Therefore, the search for new, more effective drugs involving different strategies to that current and having different targets is still on-going.
