To analyze if axial loads of 50 N and 100 N, applied on an implant of 3.75 X 10 mm (Conexão-Jaú, SP, Brazil) fixed on the central portion of a prototype of the mandible with and without support base, generate isochromatic fringes of different intensity and ways. Material and methods: The sample was a segment of the mandible with 115 mm in length, 30 mm height, and 12 mm in thickness, from a block of #7 rose wax. This matrix was adapted to a modified articulator in such way that its base could or not keep contact with the lower arm of the articulator, simply by modifying the support axis. An implant was put perpendicular to the segment of the mandible’s body and then the photoelastic model obtained. The healing abutment was screwed to the implant to receive loads from 50 N to 100 N, with the model with or without contact of its base with the inferior arm of the articulator. Results: Alterations in the reflections of the colors was observed when the implants had been submitted to loads of 50 N and 100 N with or without supported base. Conclusion: Based on the results, it can be concluded that during the photoelasticity analyses alterations in the color standards occurred depending on the support of the sample and the applied load.

Introduction and Objective: To analyze if axial loads of 50 N and 100 N, applied on an implant of 3.75 X 10 mm (Conexão-Jaú, SP, Brazil) fixed on the central portion of a prototype of the mandible with and without support base, generate isochromatic fringes of different intensity and ways. Material and methods: The sample was a segment of the mandible with 115 mm in length, 30 mm height,and 12 mm in thickness, from a block of #7 rose wax. This matrix was adapted to a modified articulator in such way that its base could or not keep contact with the lower arm of the articulator, simply by modifying the support axis. An implant was put perpendicular to the segment of the mandible’s body and then the photoelastic model obtained. The healing abutment was screwed to the implant to receive loads from 50 N to 100 N, with the model with or withoutcontact of its base with the inferior arm of the articulator. Results: Alterations in the reflections of the colors was observed when the implants had been submitted to loads of 50 N and 100 N with or without supported base. Conclusion: Based on the results, it can be concluded that during the photoelasticity analyses alterations in the color standards occurred depending on the support of the sample and the applied load.

Aesthetic medicine has been developing at a fast pace in recent years. It is necessary and ethical for anyone who undergoes any of these treatments to receive complete information on its implementation methods, as well as its consequences andadverse effects. Only once the person who would be affected by these procedures obtains truthful and impartial information, can he or she provide a legally binding consent to undergo a procedure. Thus, the information received by the patient plays a crucial role since it underlies the subject’s decision concerning the treatment.

Comparing two languages may lead to the results, which would help to understand both of the languages being under the analysis deeper, and it may be helpful to see the language from a new side. The results which are achieved by the comparative method, showing common features of the languages being compared, make the process of studying a foreign language easier. As the Tatar speaking audience does not commonly study Japanese language, studying it through the mother language may make the process of studying and acquisition less difficult. Being the representatives of agglutinative languages, the Tatar and the Japanese have common features that have to be studied by the comparative linguistics. This article deals with the constructions, which consist of verbal adverb and modal verb in Tatar and Japanese languages whose meaning is to give/to receive. Such constructions are analyzed and compared in terms of their grammatical form, semantics and considered through the lens of cultural linguistics.

The longevity of implant-supported prosthetic rehabilitation depends largely on how the masticatory forces are transferred to the implants and surrounding bone. Anatomical conditions, bone morphology and aesthetics usually dictate implant placement in less than ideal positions for prosthetic rehabilitation and sometimes it is possible to find them with different inclinations. The purpose of this paper was to compare, through photoelastic analysis, the stress distribution in a fixed prosthesis with 3 parallel implants, to the stress distribution in the same prosthesis in the existence of an angled central implant. Two photoelastic resin models were made and a polariscope was used in the visualization of isochromatic fringes formed in the models when axial loads of 2 kg, 5 kg and 10 kg were applied to a unique central point of the prosthesis. The presence of inducted tensions (preloads) was observed in the models after applying torque to the retention screws. Preloads were intensified with the incidence of occlusal forces. In the parallel implants, the force dissipation followed the long axis. The angled implant had a smaller quantity of fringes and the stresses were located mostly around the apical region of the lateral implants.

Abstract: The purpose of this research is clarity which can make it easy for Mustahiq (beneficiaries) to find business capital by borrowing capital at BAZNAS (The National Zakat Board) of Bengkulu City and the results of this study can be used as material for further study to produce legislation regarding the rights of Mustahiq in existing regulations. It is field research using qualitative descriptive methods. Descriptive research is to analyze the data that the author has obtained, the author uses a comparative analysis method, namely research that aims to systematically, factually, and accurately compare facts, situations or events in the field. From the results of research on the effectiveness of zakat funds received by the community, a total of eight asnaf (a Muslim person who is entitled to receive zakat and fitrah) received professional zakat assistance, those who are, fakir (a Muslim person who (a) has no property or income; or (b) has property or income but does not reach fifty per cent of the kifayah limit of himself and his dependants), poor, fisabilillah (the struggle, efforts and activities for the purpose of upholding and propagating the religion of Islam),  mu'allaf (a call for individuals who are non-Muslims or non-Muslims who have the hope of converting to Islam or those who are new to Islam whose faith still needs to be supported and reinforced), and musafir (traveler), as well as productive zakat for small traders in advancing their business. The distribution of productive zakat given by BAZNAS of Bengkulu City through the "Program" to mustahik in the Bengkulu City area can improve two factors of Mustahik's welfare. Keywords: productive zakat; mustahik.

Willingness to receive the newly developed Coronavirus Disease-2019 (COVID-19) vaccines is highly variable. To assess the receptiveness of a select sample of North Carolinians to COVID-19 vaccination, a brief survey was conducted among participants in the COVID-19 Community Research Partnership (CCRP) affiliated with five medical centers in North Carolina. A total of 20,232 CCRP participants completed a multiple choice, mini survey electronically between December 17, 2020 and January 13, 2021. Of the 20,232 survey respondents, 15,422 (76.2%) were receptive to vaccination. Vaccine receptiveness increased incrementally with age with those >70 years being the most willing to be vaccinated compared to all other age groups. Respondents with no previous COVID-19 diagnosis were more likely to accept the vaccine compared to those that have a previous COVID-19 diagnosis (76.6% vs 60.9%). Comparative analysis of gender, race/ethnicity, and residence locale revealed that women, African Americans, and suburban participants were less willing to get a COVID-19 vaccine. There was no difference in vaccine intent based on healthcare worker status. Of those unwilling to get the vaccine, 82% indicated that the reason was uncertainty about the safety and efficacy of the vaccine.

The article defines the basic accounting items that determine the impact on the complex of methodological principles of accounting and reporting generalization of information about intangible assets. The complex of basic accounting positions for intangible assets is proposed in the following composition: definition of the object of accounting; method of identification; response to goodwill; how to receive and how to pay; the criteria for recognizing the asset is intrinsic; method of initial assessment; revaluation model; response to impairment; conditions for the choice and application of methods of accrual of depreciation; directions of disclosure. The key methodological principles of accounting for intangible assets are systematized on the basis of a comparative analysis of the provisions of national and international standards. As a result of the comparative analysis, both conceptually similar principles and those that are characterized by significant differences are established. In particular, this applies to: the ways of obtaining and payment of the intangible assets, for which the IAS does not provide for the free receipt and payment of an intangible asset to the authorized capital of the enterprise, which emphasizes the nature of such assets in view of the obligation to receive future economic benefits; the definition of the value of internally generated goodwill is precisely in IAS, which contributes to a reasonable separation from the value of its own intangible assets in the event of the merger of enterprises; the initial valuation of the intangible assets, for which IAS prioritizes the valuation at cost rather than fair value, as defined by National Accounting Standards, due to the dependence of the usually unpopular phenomenon - the existence of an active market for such assets; the variability of the choice of depreciation methods for the intangible assets, for which IAS offers more opportunities to take into account the specifics of the use of these objects during the formation of depreciation costs; directions of disclosure of  the intangible assets information in the notes to the financial statements, which are clearly defined in the IAS. Comments on the conditions for the implementation of the requirements of national and international standards for the accounting of intangible assets at the level of economic entities from the point of view of the established differences and their consequences are given. It is proved that a much higher level of transparency of information about intangible assets is provided in the case of accounting and financial reporting by entities in accordance with the requirements of IAS and IFRS.
