Authors: Pavlova Z. , Tumbalov A. , Filtchev A. 
Published: May 2020

Abstract
The purpose of the study is to create computer program for the achievement of precise digital data processing of records performed with the “Facebow Mini-Maxi” and the facilitation of information transfer to the articulator.

Material and method: A conceptual project was developed in order to create a new software product and requirements were defined towards its capacities, which are to provide guidance for its creation. With the assistance of computer programmer, the project was implemented.

Results: The computer program “Facebow Mini-Maxi Analyzer” for digital data processing of registrants performed with the auricular type facebow was created. The program provides automatic recognition, reading, calibration and measurement of data obtained by “Facebow Mini-Maxi”. The main module gives us opportunities for measuring the values of: the sagittal condylar pathway; the arrow point angle and the length of the hinge axis. After finalizing the calculations, the software automatically generates a scheme with visualization of the parameters that significantly supports the dental technician when it comes to defining the accurate position of the models in dental articulator with individual parameters.

Conclusion: The computer program provides accurate analysis of facebow records and assists in determining individual patient movement parameters of the lower jaw. The obtained results from the analysis improve the precision of casts mounting in articulator. The program cuts down the risk of subjective error when analysing the data via manual measurement of the recorded parameters on paper carrier.

Published: May 2020

Abstract
Subacute thyroiditis is a relatively rare thyroid disease that develops after acute viral upper respiratory tract infection and manifests with neck pain, fever and transient hyperthyroidism. The diagnosis is often delayed due to the non-specific presentation and laboratory findings. It is misdiagnosed with upper respiratory tract infections, cervical lymph-adenitis, even with acute pyelonephritis. The authors present a series of 12 patients with subacute thyroiditis and discuss the main steps in the diagnosis, differential diagnosis and treatment of this disease.

Published: May 2020

Abstract
Surgical interventions for corrosive stricture of the esophagus are extremely difficult and technically challenging. In this manuscript, we present a patient with esophagectomy due to perforation of a corrosive stricture of the esophagus that underwent malignant transformation and subsequent perforation of a giant duodenal stress ulcus, which occurred 12 days after the intervention. We performed a total esophagectomy, pharyngo- and gastrostomy, suture of the duodenal perforation but the postoperative period was challenging and despite our efforts, the patient died on the 50th postoperative day due to respiratory and renal failure.

Published: May 2020

Abstract
The process of neoangiogenesis is one of the classic hallmarks of a cancer. Its intricate mechanisms have long been one of the major domains in cancer research and a hope for a therapeutic breakthrough. Last decade a new subgroup of non-coding RNA molecules was reported called microRNAs. Literally hundreds of new molecules in this class are being uncovered as pivotal regulators in virtually all intracellular processes. The aim of this study is to classify and review those microRNA molecules that have a role in the processes of tumor angiogenesis and map their places in the regulatory framework of the classical proangiogenic genes and their canonical cascades.

Authors: Moldovan Octavia-Laura , Brihan Diana-Nicoleta , Todoran Nicoleta , Rusu Aura 
Published: May 2020

Abstract

Objective: The compatibility of four binary active substances combinations adapalene – levofloxacin (ADP-LFX), adapalene – miconazole nitrate (ADP-MCZ), levofloxacin – meloxicam (LFX-MLX) and levofloxacin – miconazole nitrate (LFX-MCZ) was analysed to be comprised in new transdermal therapeutic systems. Also, the compatibility of selected active substances and four polymeric excipients (hydroxypropyl methyl-cellulose - HPMC 15000, hydroxypropyl methylcellulose - HPMC E5, ethyl cellulose - EC 10, and hydroxyethyl cellulose – HEC) was studied.

Methods: Thin layer chromatographic method (TLC) and four selected mobile phases were used. On the plate (in situ) were obtained the binary combinations (active substances and active substance-polymer).

Results: A good compatibility of ADP-LFX was found using ammonia : methanol : acetonitrile : methylene chloride 2:4:1:4 mobile phase. Using chloroform : acetone : glacial acetic acid 34:4:3 on the chromatogram of ADP-MCZ, only ADP spots appeared but without changes in the shape of the spots and Rf values. Any modifications of LFX and MLX spots (from LFX-MLX mixture) had been observed using toluene : glacial acetic acid : methanol 11:1:0.5 mobile phase, although LFX spots have remained on the baseline. Only LFX spots were visible from LFX-MLX and LFX-MCZ mixtures (ammonia : methanol : acetonitrile : methylene chloride 2:4:1:4 mobile phase). Distinctive spots were observed for ADP, LFX and MLX with variable results from no chemical interactions to limited chemical interactions when the compatibility with polymers was verified.

Conclusions: ADP-LFX and LFX-MLX mixtures were found to be compatible. ADP with HPMC polymers and LFX with HPMC E5 and HEC had presented excellent compatibility; for the other binary combinations, different analytical methods will be necessary.

Authors: Durur Hülya , Kurt Ali , Tasbozan Orkun 
Published: May 2020

Abstract
This paper proposes obtaining the new wave solutions of time fractional sixth order nonlinear Equation (KdV6) using sub-equation method where the fractional derivatives are considered in conformable sense. Conformable derivative is an understandable and applicable type of fractional derivative that satisfies almost all the basic properties of Newtonian classical derivative such as Leibniz rule, chain rule and etc. Also conformable derivative has some superiority over other popular fractional derivatives such as Caputo and Riemann-Liouville. In this paper all the computations are carried out by computer software called Mathematica.
Connections Between the Completion of Normed Spaces Over Non-Archimedean Fields and the Stability of the Cauchy Equation
Authors: Schwaiger Jens 
Published: May 2020

Abstract
In [12] a close connection between stability results for the Cauchy equation and the completion of a normed space over the rationals endowed with the usual absolute value has been investigated. Here similar results are presented when the valuation of the rationals is a p-adic valuation. Moreover a result by Zygfryd Kominek ([5]) on the stability of the Pexider equation is formulated and proved in the context of Banach spaces over the field of p-adic numbers.

Published: May 2020

Abstract
The aim of this study is to test two different methods for evaluating the in vitro antibacterial effect of Thymus fontanesii Boiss. et Reut. essential oil against standard and clinical bacterial strains responsible for bovine mastitis: the disc diffusion method or the aromatogram which allows the demonstration of the antibacterial power of essential oils on the bacterial strains tested, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923 and two strains isolated from bovine mastitis milk S. aureus and E. coli. The inhibition activity of the essential oil of T. fontanesii on bacterial strains by the two methods shows that the antimicrobial power of this oil is very important and is characterized by bactericidal and bacteriostatic action against gram negative and gram positive bacteria. The antimicrobial evaluation by the aromatogram showed good antibacterial activity against all the strains tested, the zones of inhibition of the bacteria were between 23,33±1,527mm and 37,5±3,535 mm. The search for minimum inhibitory concentrations MIC and bactericides CMB made it possible to quantitatively assess the antimicrobial power of this essential oil. In this work, the MIC was 0,625 µl/ml for all strains tested, and the lowest CMB was that of T. fontanesii against E. coli ATCC 25922 was 0,625 µl/ml.

Abstract
This study was conducted to evaluate anti-acetylcholinesterase and insecticidal and antifungal activities of the endophytic fungus Trichoderma sp, isolated from Ricinus communis L. leaves, against Locusta migratoria L. and Botrytis cinerea Pers.: Fr.. To evaluate the insecticidal and antifungal activities, different concentrations of the fungal extract were applied against L. migratoria (0.2, 0.3, 0.4 g/l) and against B. cinerea (1, 2, 3 g/l). It was found that the mortality of the targeted insects was positively proportional to fungal extract concentration and time after exposure (24, 48, 72 hours). The concentration 0.4 g/l appeared to be the most effective after 72 hours with mortality rate of 56.52%. Regarding antifungal activity, the concentration 3 g/l was the most effective against B. cinerea after 7 days, with an inhibition rate of 92.06% (excellent antifungal activity). Moreover, it was found that at 4 ug/ml the fungal extract had a maximum inhibitory capacity of Ache of 80% for acetylcholenesterase. Preliminary phytochemical analyses revealed the presence of alkaloids, flavonoids, phenols and saponins. In addition the colony of this endophytic fungus produced chitinases and proteases, which explained its important antifungal and insecticidal activities.

Published: May 2020

Abstract
In the present study, some 2- and 3-substituted piperidin-4-ones (A1-A3
) were chosen as proton acceptor and maleic anhydride was chosen as proton donor. Piperidin-4-ones (A1, A2 ---amp--- A3
) were mixed with maleic anhydride in ether medium and the corresponding molecular adduct products (B1, B2 ---amp--- B3
) thus obtained were collected and purified. The 1H and 13C NMR spectra were recorded for piperidine-4-one and their addition compounds. The 1H and 13C NMR chemical shifts of products (B1, B2 ---amp--- B3
) are analyzed and compared with those of the corresponding piperidine-4-ones (A1, A2 ---amp--- A3
). In order to confirm the formation of molecular addition compounds the GC-Mass spectrum was recorded for all adducts B1-B3 and the fragmentations patterns were analyzed.
Enhancement of tartaric acid modified washing solutions for lead decontamination of tropical soils
Authors: Etim Effiong Ukorebi 
Published: May 2020

Abstract
Tartaric acid is generally not an effective soil washing solution, hence this study focuses on enhancing its usage for soil-Pb decontamination. Three tropical soil types (sandy, clay and loamy) with different lead concentrations were subjected to single batch washing using 0.01, 0.1, 0.5 and 1 M tartaric acid with 5% and 10% KCl modification at 3% soil-pulp-density for 2, 6, 12 and 24 h washing time. The optimum washing conditions were 1 M tartaric acid at 24 h washing time, with Pb removal efficiency: sandy- 94.3%, clay-67.6% and loamy-36.8%. Modification of tartaric acid with 5% and 10% KCl brought about some degree of enhancement of Pb removal efficiency especially for clay and loamy soils. Removal efficiency for 5% KCl modification were: sandy-97.9%, clay-96.2% with 1 M tartaric acid at 24 h washing time, loamy-76.7% for 0.5 M tartaric acid. Similarly, 10% KCl modification were: sandy-96.7%, clay-97.2% for 1 M tartaric acid at 24 h, loamy-82.1% for 0.5 M tartaric acid. Removal efficiency was soil concentration dependent. Generally, removal efficiency increased with increasing tartaric acid concentrations and washing time. Tartaric acid washing is promising and recommended in events of moderate contamination and 10% KCl modification in event of high level contamination. Further study is needed on enhancing very low concentrations of tartaric acid for large scale applications.

Authors: Puszkarz Adam K. , Wojciechowski Jarosław , Krucińska Izabella 
Published: May 2020

Abstract
The article presents the results of an attempt to use high-resolution X-ray micro-computed tomography (micro-CT) to model the thermal insulation of clothing as one of the most important parameters affecting the heat balance between a human and his/her surroundings. Cotton knitted fabric applied in functional clothing for newborns and aramid woven fabric used in multilayer protective clothing for firefighters were the tested materials. The 3D models of real textiles based on micro-CT images were developed. Next, the models were applied to heat transfer simulations using the finite volume method. The usefulness of the models was experimentally verified using thermography with real textiles. The simulation results were consistent with the measurement results and confirmed the relationship between the thermal insulation and geometry of the textiles on the one hand and the physical parameters of the raw materials from which they were made on the other hand.

Authors: Khanna Archana , Koley Shyamal 
Published: May 2020

Summary

Study aim: In a volleyball game, multiple elements can influence competitive success, e.g. height, arm span and other anthropometric variables. The present cross-sectional study was undertaken to find out whether any differences exist between Indian inter-university male and female volleyball players as well as between players and a reference group in terms of anthropometry and handgrip strength.

Materials and methods: The present cross-sectional research was conducted on 114 randomly selected Indian inter-university male (n = 50) and female (n = 64) volleyball players aged 18–25 years. An equal number of reference group individuals who did not participate in any exercise or training programme were also taken. Height, body weight, body mass index (BMI) (kg/m2), hand length, hand breadth, second digit length, fourth digit length, second and fourth digit ratio (2D/4D ratio), upper arm length, forearm length, total arm length, upper arm circumference, hip circumference; humerus and femur biepicondylar diameters, handgrip strength (dominant/non-dominant), arm muscle area, arm area, arm fat area, arm fat index, % body fat, and % lean body mass were measured with equipment including an anthropometer, sliding caliper, handgrip dynamometer and skinfold caliper using standard techniques. The data were analysed using SPSS version 17.0. Student’s t-test was applied for the comparison of data between players and the reference group. Differences between the groups were analysed using the oneway ANOVA test. Bonferroni post hoc test was applied after application of the ANOVA test. Effect size was also calculated. Statistical significance (p < 0.05) was indicated using a 5% level of probability.

Results: Male volleyball players had higher mean values in height, body weight, hand length, hand breadth, second and fourth digit length, dominant and non-dominant handgrip strength, humerus and femur biepicondylar diameter, upper arm length, forearm length and total arm length, arm muscle area, arm area and percent lean body mass than the reference group. Similar findings were observed between female players and the reference group also. Statistically significant differences (p < 0.05–0.001) were also observed between male and female players except BMI, 2D/4D ratio, and arm fat area. These findings were supported by the effect size (η) calculations.

Conclusion: Volleyball players had better height, weight, hand and arm anthropometrics, handgrip strength and % lean body mass as compared to the reference group. Significant differences were found in anthropometry and handgrip strength between players and reference group individuals, suggesting that these findings could be very useful for player selection and talent identification in sports.

Summary

Study aim: The purpose of this study was to determine the prevalence and factors associated with pain and musculoskeletal injuries in Brazilian kickboxers.

Material and methods: This is a cross-sectional study composed of a population of kickboxers from the academies affiliated to the Rio Grande do Norte State Federation of Kickboxing. The study was conducted by means of a questionnaire regarding their demographic data, graduation and level of participation in the modality, routines of procedures during training, and pain/ discomfort regions and respective intensities. In addition, the characteristics, types, and regions of the injuries were evaluated.

Results: Of the 132 kickboxers included, a high prevalence of pain (84.09%) was observed and associated with the female gender (OR = 3.62; CI95% 1.29–10.13) and body mass index (OR = 0.80; CI95% 0.71–0.91). In addition, the kickboxers presented a moderate percentage of injuries (40.91%) that were associated with longer training time (OR = 5.82; CI95% 2.68–12.61) and contact level in the training sessions (OR = 3.53; CI95% 1.85–6.72).

Conclusions: There was a high prevalence of musculoskeletal pain in kickboxers, mainly associated with female gender and with lower body mass. Musculoskeletal injuries were moderately prevalent in kickboxers who trained more than one hour per session and with an intense contact level.
William O. Douglas and The Assault on Objectivity
Authors: Halper Thomas 
Published: May 2020

Abstract
William O. Douglas, venerated by some and reviled by others, was very much his own man, disdaining his colleagues on the bench and the work they produced. For him, the point of judging was simply to do justice. However, justice is not always self evident, and legal norms and values, like objectivity and stare decisis, are ignored at a high cost. Nor, as it turns out, was his carefully carved authentic persona more than a mask of lies.
Directions for the Study of Masculinity: Beyond Toxicity, Experience, and Alienation
Authors: Yaeger Dylan A. 
Published: May 2020

Abstract
The relationship between the law and masculinity has not been as thoroughly examined as the relationship between the law and feminism or, more generally, between the law and gender. Yet, the reach of masculinity stretches deep into the very fiber of the law. Masculinity has for too long served as an invisible bedrock on which the law founded both its substance and method. The struggle for formal equality during the last half century sought the elimination of the masculinist bias, but has only exposed the extent of the entrenchment. The popular idea is that the law exists in a removed and exalted position where it sits in judgement of a pre-existing and fully formed masculinity. Indeed, much of the internal coherence of the law is premised on the integrity of the subject and the propagation of sexual difference. Thus, the law is precluded from acknowledging or engaging with its own productive power and vacuously characterizes itself as a neutral arbiter. Today, while significant changes occur in sex and sexuality, the study of masculinity appears theoretically stagnant.
Part I of this paper distinguishes between masculinity studies and the men's movement and explains the relationship of each to feminist theory. Part II looks at how the power of the law works and how masculinity studies is an effective tool to help understand how that power manifests and is employed. Part III examines the relationship between feminist legal theory and masculinity studies with a particular focus on two areas where I view masculinity studies as having successfully employed insights from feminist theory. Finally, Part IV considers four areas where I suggest masculinity studies could better incorporate certain insights from feminist theory, which would result in a more rigorous understanding of the relationship among power, masculinity, and law, and point masculinity studies in a more nuanced direction. To advance this critique, the paper analyzes underlying arguments that support the power of law based in classic liberal political theory. It employs recurrent critiques of the law, and of liberalism more generally, found in Feminist Legal Theory, Critical Race Theory, Queer Theory, and Critical Legal Studies to reveal the law as always already intertwined with masculinity.
