SUMMARY

Purpose
To evaluate the effect of short curing time using a high-radiant emittance light on polymerization shrinkage vectors in different consistency bulk-fill composites (BFRCs) using micro-computed tomography.

Methods and Materials
Radiopaque zirconia fillers were homogeneously incorporated and functioned as radiopaque tracers into two regular-paste: TBFill (Tetric EvoCeram Bulk Fill) and TPFill (Tetric PowerFill), and two flowable (n=6): TBFlow (Tetric EvoFlow Bulk Fill) and TPFlow (Tetric PowerFlow) resin composites. Class I cavities (4 mm depth × 4 mm length × 4 mm width) were 3D-printed and filled in a single increment: TBFill and TBFlow were light-activated using a Bluephase Style 20i (10 seconds in high-mode); TPFill and TPFlow were light-activated using a Bluephase PowerCure (three seconds). The same adhesive system (Adhese Universal) was used for all groups. Microcomputed tomography scans were obtained before and after light-activation. Filler particle movement was identified by polymerization shrinkage vectors at five depths (from 0–4 mm): top, top-middle, middle, middle-bottom and bottom.

Results
TPFlow showed the lowest total vector displacement, followed by TBFlow, TBFill and TPFill, significantly different among each other (p&lt;0.05). Generally, BFRCs showed decreased vector displacement with increased depth, and higher displacement at the top-surface (p&lt;0.05). Qualitative analysis showed a similar pattern of vector magnitude and displacement for groups TBFill and TPFill, with displacement vectors on occlusal (top) surfaces toward the center of the restoration from the top to middle areas, and relatively limited displacement at the bottom. TBFlow and TPFlow showed more displacement on the occlusal (top).

Conclusions
Short curing time with high-radiant emittance on fast-curing BFRCs was shown to be a feasible option in terms of vector displacement. Flowable BFRCs presented lower vector displacement than their regular-viscosity versions.

Published: December 2022

Objective:Despite the common clinical impression that patients with a history of drug use are challenging to anesthetize with local anesthesia, literature on this clinical phenomenon is sparse. The objective of this pilot study was to assess if differences in local anesthetic efficacy for dental treatment exist between marijuana users and nonusers.Methods:Subjects were healthy adult males and females who qualified as either chronic marijuana users or nonusers. All subjects had an asymptomatic, vital maxillary lateral incisor that responded to an electric pulp test (EPT). A standard maxillary infiltration injection technique was employed using 1.7 mL 2% lidocaine with 1:100,000 epinephrine over the test tooth, and the tooth was tested with an EPT at 3-minute intervals.Results:A total of 88% of nonusers (15/17) and 61% of users (11/18) were successfully anesthetized, defined as anesthesia onset within 10 minutes and lasting at least 15 minutes. The difference in the proportion of anesthetized subjects was not statistically significant (P = .073). For subjects with successful anesthesia, there was no significant difference between nonusers and users in the onset or duration of anesthesia.Conclusion:No significant differences in local anesthetic efficacy with respect to local anesthetic success, onset, or duration of action were found between chronic marijuana users and nonusers. However, larger studies are likely needed to provide more definitive evidence.

ObjectiveIn recent years, opioid misuse has resulted in much scrutiny on providers' prescribing habits. The purpose of this study was to analyze prescribing habits in the context of third molar extractions as a model for promoting better postsurgical pain management.MethodsThis was a cross-sectional survey of oral maxillofacial surgeons in Connecticut and New Jersey. A total of 291 practitioners were contacted to complete an online survey using Qualtrics Research Services to determine prescribing habits following third molar extractions.ResultsThe most common approach for postoperative analgesia was nonsteroidal anti-inflammatory drugs (NSAIDs) and an opioid/acetaminophen (APAP) combination as 2 separate prescriptions, reported by 36% of participants. The combination of hydrocodone/APAP was the most common opioid formulation, and an average of 10.93 ± 4.51 opioid pills were prescribed with a maximum of 20 pills reported. Most providers (79%) consistently provided patients with opioid information. Only 22% reported always checking opioid-monitoring programs; however, providers were more likely to check if prescribing more than ∼11 opioid pills (P = .0228). Most reported using dexamethasone (82%) and bupivacaine (56%) intraoperatively, while ketorolac was less common (15%). No association was found between the quantity of opioids prescribed and the use of intraoperative ketorolac, steroids, or bupivacaine (P &gt; .05).ConclusionThere remains to be a universal standard for using opioids for postoperative pain management in dentistry. Providers should be mindful when prescribing opioids and consider using NSAIDs and APAP for baseline pain plus a separate opioid prescription for breakthrough pain. Additional focus on minimizing the quantity of opioids prescribed and self-reflecting on prescribing and practice habits to further reduce opioid-related complications is warranted.
Concepts and main signs of administrative responsibility: analysis of modern administrative and legal literature
Authors: Drofych Yu.V. 
Published: December 2022

In the article, the author states some principle theses regarding the essence of administrative responsibility. In particular, it was determined that in modern concepts of administrative responsibility, the problem of assessing law from general systemic and philosophical positions, which reflects the general laws and principles of society, integrating the substantive and phenomenal characteristics of socio-legal reality, which includes theoretical and methodological criteria for assessing law in relation to absolute (legal substance) and derived order (optimal requirements of social reality, concentrated in traditional mentality).
The author supports the thesis that one of the defects of the administrative-delict legislation is the normative consolidation of provisions regarding the possibility of establishing the composition of a misdemeanor and responsibility for its commission, as well as the application of relevant norms outside the Criminal Code. This approach to the construction of legislation on administrative responsibility is a condition for the occurrence of collisions, which actually discredit both the legislator and the law enforcer. Emphasis is placed on the fact that administrative offenses are socially harmful, anti-social phenomena. Recognizing administrative offenses as socially harmful, and not socially dangerous, is the criterion by which it becomes possible to distinguish between crimes and administrative offenses.
On the basis of the above, the author believes that administrative responsibility is a complex legal mechanism of the state’s response to the manifestation of administrative wrongdoing, which contains material and legal grounds and the procedural order of proceedings in cases of administrative offenses. The basis of administrative responsibility is differentiated administrative wrongdoing, composition of administrative offense; administrative penalty (substantive legal aspect) and procedural form.

Creating a supersonic jet in the laboratory is both a challenging and an expensive task. The supersonic flow is sensitive to the shape of the wall bounding it because a shock could be developed at the sharp edges. Moreover, the growth of boundary layer, within and outside the nozzle, makes the design of a convergent–divergent nozzle a sophisticated work. The present work proposes an optimization algorithm that is believed to be efficient in constructing a nozzle contour to deliver a shock-free radially uniform flow at the exit plane. The steepest descent optimization technique is employed to obtain the shape with minimum radial velocity at the outlet, along with restriction on the inlet angle, i.e., the angle of divergence immediately downstream the throat. Three different ways of implementing the constraints are discussed and compared with the experimental results after fabricating the nozzle. The optimized nozzle shows a potential core of 7 throat diameters height at the nozzle exit and an axial extent of 28 throat diameters downstream the exit plane. Further, the nozzle appears to operate efficiently even after increasing the nominal total temperature by 25% or decreasing it by 50%.

Factors for Building an Intellectual Property Culture
Authors: Kuznetsova Tatiana V. , Tokareva Anastasia A. 
Published: December 2022

In modern conditions of innovative processes development, the creative personality, as well as the appeal to human capital, comes to the fore. The ideas, technologies and developments generated by human creative work, as well as the transaction (considered in the article as a method of social retraining) of intellectual property, become the realities of modern society. In this regard, the term “intellectual property culture” is of great importance, which is studied both by followers of this phenomenon and by specialists working in the field of intellectual property. A number of authors note that there is no understanding of intellectual property among people, its culture has not been formed.This research is relevant because it can contribute to achieving the goals of scientific and technological development, innovative transformation of society, activates a creative personality to produce new results of intellectual activity. The article gives its own definition of intellectual property culture. A significant role in its formation can be played by libraries, which are transformed and acquire new functions of educational and social-communication interaction.The activities of the All-Russian Patent and Technical Library of the Federal Institute of Industrial Property to popularize the field of intellectual property through the “soft power” factor are aimed at working with various target audiences. For adults, they hold thematic meetings on diverse intellectual property issues. In addition, they pay great attention to working with patent information to improve the effectiveness of research in scientific and technical fields. The patent information is a reflection of the results of scientific and design work and makes it possible to evaluate the idea of an invention and determine the starting point of the search for new solutions.As a conclusion, the article presents direct, indirect and prospective factors of the influence of library activities on the formation of intellectual property culture.
Soviet Visual Symbols in Internet Memes
Authors: Kostoglotov Dmitry A. 
Published: December 2022

The article analyzes Soviet symbols that are present in Internet memes — an important, developing part of modern communication. Despite the fact that the Internet meme has many definitions, the article presents a clear, heuristic view that considers the Internet meme as an element of the emerging metalanguage. Such an understanding is possible due to the structure of an Internet meme, which contains an unchangeable part (language) and a changing part in every new picture (speech). This optics allows us to consider an Internet meme as a saying available for analysis.Using this provision, the article examines the existence and functioning of Soviet symbols in Internet memes. They are usually the subject of various studies of cultural and historical memory. Despite the great attention paid to the Soviet memory discourse, researchers mainly focus on the confrontation of positive and critical memory about the Soviet experience and on the construction of such memory. The author puts forward the thesis about the presence of Soviet symbols outside this discourse and its consolidation in cultural memory and everyday communication on the Internet. The involvement of Soviet symbols can be found outside the paradigm of memory construction and any explicit political discourses. At the same time, Soviet symbols regularly appear in new Internet memes, acting as a universal, understandable code of culture. Symbols such as the hammer and sickle, the red star, the May Day demonstration, figures of leaders and many others serve as a matrix of understanding for everyday communication, purified from purely historical discourses.Using various examples, the article demonstrates symbols, seemingly irrelevant to a young audience, which are successfully used in Internet memes that play out a variety of situations. This approach makes it possible to implement the interdisciplinary paradigm in the studies of cultural memory in the digital environment, using the methods of cultural theorists and the methods of media researchers.
Nikolay Karazin’s Magazine Graphics for the Samara Expedition of 1879

Published: December 2022

The article analyzes the graphic series of the artist N.N. Karazin, prepared by him on the basis of the Samara scientific expedition to Central Asia in 1879, and published in the magazines “Niva” and “World Illustration” in 1879 and 1880, respectively. These series have not yet been considered by art historians, which makes relevant this study, as well as the artistic development of the topic of Central Asian ethnography in general. The author applies the method of comparative analysis; uses fragments of literary works by N.N. Karazin himself (ethnographic essays from the mentioned magazines), as well as by other writers and researchers of Central Asia; and offers new interpretations of some traditional types of Central Asian society (hajji, mullah, bacha).The article opens with an analysis of a series of art works from the magazine “World Illustration” in 1880, which shows all the main stages of the expedition (indicating geographical objects and settlements) and presents the most complete and detailed ethnographic material.The graphic series, published in the magazine “Niva” in 1879, includes four engravings depicting Turkmens from the Teke clan, which are already beyond the scope of ethnographic sketches and can be awarded the status of ethnographic paintings.The article shows that N.N. Karazin’s methods of work during this period, as well as during his participation in the Amu Darya scientific expedition in 1874, allow us to consider him as a representative of the voyage pittoresque (pictorial journey) genre in Russia in the second half of the 19th century.
