ANÁLISE COMPARATIVA ENTRE AS PROPRIEDADES MECÂNICAS OBTIDAS NO AÇO DAMASCO E NOS AÇOS BASES SAE 1095 + UHB 15N20
Authors: Kreutz Gabriel Alan , Izquierdo Rafael Crespo
Published: March 2023

O aço damasco tem se destacado dentre os materiais utilizados na fabricação de facas artesanais e lâminas em geral. As principais características que se destacam no uso do aço damasco na cutelaria são a boa temperabilidade, a ótima durabilidade do fio e os detalhes típicos na lâmina. O presente trabalho tem como objetivo analisar as propriedades mecânicas de amostras de uma peça de aço damasco obtida no processo de caldeamento, verificando a influência dos aços base SAE 1095 e UHB 15N20 na sua fabricação. A partir do forjamento do aço damasco, foram realizados tratamentos térmicos de normalização, têmpera e revenimento nos corpos de prova utilizados nos experimentos. Assim, os corpos de prova em aço damasco e dos aços bases SAE 1095 e UHB 15N20 foram submetidos aos ensaios mecânicos de impacto, dureza, tração e metalográfico. Os resultados obtidos para o aço damasco foram de, aproximadamente, 57 Rockwell C no ensaio de dureza, de 16 Joules no ensaio Charpy e de 1462 MPa no ensaio de resistência à tração. Tais resultados indicam que as propriedades do aço damasco foram iguais ou superiores às propriedades dos aços base, evidenciando que os aços SAE 1095 e UHB 15N20 não influenciam na fabricação do aço damasco.
COMPARATIVO ENTRE OS MÉTODOS DE CONCRETO ARMADO E CONCRETO PRÉ-FABRICADO PARA FINS DE CRONOGRAMA DE OBRA E ORÇAMENTO DE UM EMPREENDIMENTO
Authors: Bergonci Greici , Schmitz Rebeca Jéssica
Published: March 2023

A competitividade no mercado da construção civil promove a busca por métodos construtivos mais econômicos e de menor tempo de entrega das obras. O uso de estruturas pré-fabricadas vem crescendo em virtude da sua agilidade de construção, todavia, o concreto armado ainda é o método mais difundido em construções. Dentro desse contexto, o presente trabalho teve como objetivo realizar um comparativo entre orçamentos e cronogramas de um empreendimento projetado com esses dois tipos de estruturas. Utilizou-se uma edificação projetada por Schneider (2020), de onde foram consultados os quantitativos necessários para proceder com as análises. Foi utilizada como base para estudo a tabela SINAPI, sem desoneração, e o mês de agosto de 2021, além de pesquisa de mercado com fornecedores da região do Vale do Taquari - RS para os elementos pré-fabricados. A definição da duração das atividades se deu através de pesquisa com profissionais da construção civil, e de análises dos coeficientes de produtividades da SINAPI. Obteve-se como resultado uma economia de 67% com a estrutura moldada in loco, em contrapartida, a pré-fabricada demandou 51 dias a menos de trabalho quando utilizado os resultados da pesquisa com profissionais e 37,8 dias a menos com o resultado dos coeficientes da tabela SINAPI, confirmando a sua agilidade de execução. Devido a grande diferença de valor entre os orçamentos, entende-se que o uso do pré-fabricado só se justifica caso o empreendimento em funcionamento apresente alta lucratividade, caso contrário o concreto armado é a opção recomendada.
Impact of interest rate, exchange rate, and inflation on commercial banks’ performance
Authors: Merko Flora , Habili Mateus
Published: March 2023

This study aims to measure the impact of interest rates, exchange rates, and inflation on the performance of commercial banks in Albania, using monthly data from December 2015 to May 2022 obtained from the Bank of Albania and the Institute of Statistics of Albania (INSTAT). The multiple regression model measures the relationship between the dependent variable (ROA) and independent variables (inflation, interest rate, and exchange rate). The estimation results reveal that the interest rate variability has a high impact on the financial factor ROA. In contrast, the variability of the exchange rate harms it. The effect of variable nominal effective exchange rate (NEER) on ROA is low, and inflation negatively influences it. The model has resulted within all the criteria related to the regression analysis but with a low importance level. The important conclusion of this study is that the combination of variables, inflation, exchange rate, and interest rate, does not measure the impact of inflation on the performance of commercial banks. Other micro and macroeconomic factors can measure this impact.

Authors: Zhao Xiang , Cheng Yuan , Zhang Meng , Qianda Bianba , Zhuoma Bai Ma , Bianbayangzhen * , Zheng Yao , Zhang Shuo , Zhao Huiying
Published: March 2023

Background: No study has directly compared the efficacy of
nirmatrelvir-ritonavir and azvudine for treatment. The efficacy of these
two drugs at high altitudes was compared. Materials and
Methods: This was a retrospective cohort research on hospitalized
patients with COVID-19 who were treated with nirmatrelvir-ritonavir or
azvudine in Tibet between August 1 and September 30, 2022.
Results: The electronic health data of 731 patients were
retrospectively reviewed. Nirmatrelvir-ritonavir and azvudine groups
enrolled 338 and 147 patients, respectively. Among patients with mild,
common, and severe (including critical) COVID-19, there was no
difference in the median duration of hospitalization between treatment
with nirmatrelvir-ritonavir and that with azvudine: 8 (5–10.25) vs. 9
(5–13) (P=0.096); 8 (5–11) vs. 8 (5–13) (P=0.227); and 13 (7–17.75)
vs. 10 (7.5–17.5) (P=0.994) days, respectively. Moreover, patients in
the nirmatrelvir-ritonavir group had a shorter median time for nuclear
acid negative conversions (NANC) than those in azvudine group: 6 (4–9)
vs. 10 (6.25–13.75) (P=0.000), 8 (5–12) vs. 10.5 (7–14) (P=0.013),
and 7 (5.25–12.75) vs. 15 (7.5–23.5) (p=0.023) days, respectively.
Conclusion: Azvudine yielded a longer time for NANC and an
equivalent duration of hospitalization and may have comparable efficacy
with nirmatrelvir-ritonavir, making it a viable treatment option for
COVID-19.
Investigation of Bovine Serum Albumin specific IgE expression in horses
Authors: Perry Elizabeth , Delph Katherine , Blevins Christopher , Knights Kaori , Springer Nora , Davis Elizabeth
Published: March 2023

Background: Neonatal foals are born essentially agammaglobulinemic and
therefore must ingest colostrum or receive immunoglobulins to maintain
health. Failure of passive transfer treatment involves administration of
equine colostrum, plasma or commercial powdered colostrum (CPC).
Anecdotal reports suggest a risk of anaphylaxis associated with plasma
transfusion in neonates that received CPC prior to gut closure. Bovine
serum albumin (BSA) in CPC may serve as a target for BSA-specific
immunoglobulin E (IgE) in donor equine plasma. Objectives: To determine
presence of BSA-specific IgE in samples collected post-routine
vaccination in healthy horses, horses experiencing adverse vaccine
reactions and commercial equine plasma. Study Design: Prospective
Observational Methods: Serum was collected from 65 healthy horses at day
0, 14, 28, 90, 180, 270 and 365 post-vaccination, 26 horses after
vaccine reaction at day 1, 180 or 270 post-vaccination, 4 horses not
vaccinated and 10 horses from a commercial plasma donor herd.
BSA-specific IgE was determined using enzyme-linked immunosorbent assay
(ELISA). Results: BSA-specific IgE was not detected in non-vaccinated
horses and was identified in all vaccinated horses. Younger horses
demonstrated higher fold changes in post-vaccination BSA-specific IgE
expression compared to older horses. No significant difference in
BSA-specific IgE levels between commercial plasma donors and healthy
horses was identified. No significant difference in post-vaccination
anti-BSA IgE levels between reactor and healthy horses at day 180 and
270 post-vaccination were identified. Main Limitations: Small number of
reactor horses at day 180 and 270 post-vaccination with most samples
being collected 24 hours. There were no healthy horse samples for 24
hours post-vaccination; therefore, it was not possible to compare the
two groups at this timepoint. Conclusions: Horses may express BSA
specific IgE following vaccination. There may be risk of
hypersensitivity type reaction when veterinarians administer commercial
plasma to neonatal foals that have consumed CPC prior to gut closure.

Leucine tunes hydropathy of class A GPCRs
Authors: Baumann Christian , Zerbe Oliver
Published: March 2023

Leucine and Isoleucine are two amino acids that differ only by the
positioning of one methyl group. This small difference has however
important consequences in α-helices, as the β-branching of Ile results
in helix destabilization. We set out to investigate whether there are
general trends for the occurrences of Leu and Ile residues in structures
and sequences of class A GPCRs (G protein-coupled receptors). GPCRs are
integral membrane proteins in which α-helices span the plasma membrane
seven times and which play a crucial role in signal transmission into
the cell. We found that Leu side chains are generally present in less
densely packed regions and are more protein-surface exposed than Ile
side chains. We explored whether this difference might be attributed to
different functions of the two amino acids and tested if Leu adjusts the
hydrophobicity of the transmembrane domain based on the Wimley-White
whole-residue hydrophobicity scales. In class A GPCRs, Leu decreases the
variation in hydropathy between receptors and Leu content correlates
positively with hydropathy calculated without Leu. Both measures
indicate that hydropathy is tuned by Leu. To test this idea further, we
generated protein sequences with random amino acid compositions using a
simple numerical model, in which hydropathy was tuned by adjusting the
number of Leu residues. The model was able to replicate the observations
made with class A GPCR sequences. We speculate that Leu tunes the
hydropathy of the transmembrane domain of class A GPCRs to facilitate
correct insertion into membranes and/or for stability within them.
Forgive or complain: Interpersonal distance modulates reactive attitudes and neural responses toward wrongdoers
Authors: Li Sijin , Cheng Si , Shangguan Chenyu , Su Ling , Li Xu
Published: March 2023

While the effect of interpersonal distance on forgiveness has been
investigated over the past few years, it remains unclear whether this
facilitating effect holds even when measured implicitly. Meanwhile,
though cognitive control and the corresponding prefrontal cortex play a
prominent role in forgiveness processing, the neural mechanism
underlying forgiveness toward varied wrongdoers is largerly unexplored.
Here, forty-two participants initially underwent noise offense either
from their friend or stranger, followed by a word identification test to
examine their reactive attitude, during which they were presented with
word-name combinations and required to categorize forgive- or
complain-label words while ignoring the names of their friends or
strangers below. A shorter reaction time reflects more congruence with
one’s implicit attitude. Electroencephalogram was recorded during the
word identification test. Behaviorally, while individuals reacted faster
to forgive-friend relative to complain-friend pairings, no such reaction
bias was found for the stranger-wrongdoer, which suggests that
individuals were more inclined to forgive someone close. Regarding the
EEG/ERP results, forgive-friend elicited lower alpha oscillation and
more negative frontal alpha asymmetry (FAA) value than complain-friend
combinations, suggesting increased and dominant activity in the right
prefrontal network during forgiveness toward friends. Whereas complain-
relative to forgive-stranger combinations elicited larger P3 amplitudes,
suggesting a neural encoding bias to information associated with
complaints about stranger-wrongdoer. These findings provide objective
evidence for the benefits of closeness on forgiveness, which broaden
previous findings depending on explicit measures into situations where
forgiveness was measured implicitly and thus minimized confounding
factors such as social desirability.

Published: March 2023

Background/Aim. One of the disadvantages of the cement-retained fixed implant-supported restorations is the residual cement, which is found on the superstructure after the cementation procedure and has been identified as a risk factor for the occurrence of peri-implantitis. The aim of the study was to examine the influence of cementation techniques on the amount of residual cement at different levels of demarcation of the abutment in relation to the gingiva in the process of cementing restorations on implants. Methods. The research was conducted in in vitro conditions on casts obtained after implant placement. The abutments are milled at the level of the gingiva, 1.5 mm subgingivally and 3 mm subgingivally. Zirconium dioxide ceramic restorations were cemented using a standard cementation technique, a cementation technique using Teflon tape, and a precementation method using a silicone replica of the abutment and a 3D printed replica. The amount of residual cement was measured by photograph analysis. Adobe Photoshop was used for software analysis of photographs and determination of cement surface. Statistical data processing was per-formed in the SPSS program, and the Kruskal-Wallis test was used for data analysis. Results. A comparative analysis of the effectiveness of cementation techniques at the gingival margin level revealed a statistically significant difference in the amount of residual cement in relation to the cementation technique (p < 0.001). Analyzing the cementation technique effectiveness at the level of the finish line, 1.5 mm subgingivally, it was established that there was a statistically significant difference in the amount of residual cement compared to the cementation technique (p = 0.001). Comparing the effectiveness of cementation techniques at the 3 mm subgingival finish line level, it was established that there was a statistically significant difference in the amount of residual cement compared to the cementation technique (p < 0.001). Conclusion. Subgingival localization significantly affects the amount of residual cement in fixed prosthetic restorations on implants. Applying precementation techniques significantly reduces the amount of residual cement.
Public interest, general interest and private interest as legal concepts
Authors: Prica Milos
Published: March 2023

The multifaceted content of public interest pertaining to some subjects of
the legal order has not been the subject matter of thorough theoretical
consideration in literature, which does not recognize the need to clearly
distinguish the concept of public interest from the concepts of general
interest and private interest in the legal order of a state governed by laws
(Rechtsstaat). There are substantial differences between public interest,
general interest and private interest. General interests are dynamic
expressions of the general (common) good. Private interests are dynamic
expressions of private legal goods of individual subjects of the legal
order. Public interest is a relational determinant in the legal order of a
state governed by laws. Thus, unlike general interests and private interests
as substantial categories, public interest has a relational character, as it
serves to regulate relations between legal interests as substantial
categories. In the order of a legal state (Rechtsstaat), public interest is
a regulatory determinant of various goods and interests, which is anchored
in-between general, special and private interests, public and private
sphere, publicity and privacy, the interventionism of public authorities and
the civil society, the institutional order of the public authority and the
institutional order of the territorial.
Ethnic identity of the Bunjevci from Backa in the population censuses: 1850-2011
Authors: Horvat Aleksandar
Published: March 2023

The aim of this paper is the analysis of different forms and transfor?mations
in defining and declaring the ethnic identity of the people of Bunjevci from
Backa in the population census in the territory of today?s Vojvodina in the
period from 1850 to 2011, as well as the circumstances that influenced the
modalities of expressing their ethnicity in different state frameworks -
first in the Kingdom of Hungary, then in the Kingdom of Yugoslavia and
socialist Yugoslavia, and finally in the Republic of Serbia. The subject of
the research is the official results of certain censuses, along with the
analysis of political, social and cultural-educational factors that were of
the importance to the people of Bunjevci when declaring their ethnic
affiliation. Also, the paper analyzes the historical context and social
relations that had a decisive influence on the transformations in the
declaration of ethnic identity, including various national integration
processes in the area of Backa. As a consequence of the intersection of
different integration models within one population, two forms of identity
were shaped and the ethno-national duality of the Bunjevci and
Bunjevci-Croats is present to this day. Analyzing the ethnic identity of the
Bunjevci through the official results of the population census contributes
not only to better under?standing of the complexity of the process of
building awareness of one?s own identity, but also of the specificity of the
case of the Bunjevci, who are still the subject of conflicting and mutually
opposing interpretations in scientific and public discourse.
Differential-diagnostic parameters of motor speech disorders
Authors: Jovanovic-Simic Nadica , Petrovic-Lazic Mirjana , Ilic-Savic Ivana
Published: March 2023

Changes in speech may be the only evidence of neurological disease in the early stages of its evolution and sometimes the only significant symptom in a pro?gressive neurological condition. The relationship between speech and motor control of speech is complex and two-way, and systematic research into the nature of these interactive processes has the potential to deepen our understanding of the typical as well as patho?logical development of speech. The aim of this paper is to present the basic diagnostic characteristics of motor speech disorders in the early period based on a review of the relevant literature, with an emphasis on diagnosis and early intervention. The literature search was performed through the Google Scholar Advanced Search search engine and the Consortium of Libraries of Serbia for Unified Procurement - KoBSON. The multi?factorial nature of motor speech disorders indicates that effective diagnosis and treatment planning require a dynamic, process-oriented approach aimed at describing the underly?ing deficits that characterize these disorders. A review of previous studies shows that recognizing and understanding motor speech disorders contributes to a more complete clinical understanding of other conditions related to motor speech disorders, allowing us a better insight into the treatment of motor speech disorders. Accurate diagnostic methods and effective early intervention programs are crucial to limit the short-term and long-term negative impact of motor speech disorders on an individual?s quality of life.
Multidisciplinary approach to restore esthetics and function in a young patient with three consecutive impacted teeth: a case report with 18-month follow-up

Published: March 2023

This case report describes the orthodontic treatment of an 11-year-old patient with three maxillary impacted teeth on the right side. Cone-beam computed tomography showed that these teeth were close together, with the lateral incisor in a lower position, followed by the central incisor, and the canine in a more apical position. Treatment included applying traction to these teeth. A transpalatal arch was used as an anchorage device, and surgical exposure of the lateral incisor was performed for traction with an elastic chain toward the hook welded to the 0.017 × 0.025-inch steel segmented arch. Subsequently, the central incisor was surgically exposed, elastic chains were used, along with a 0.016-inch steel arch with a box loop for correcting the tooth position. The canine spontaneously began to erupt, and a 0.017 × 0.025-inch TMA segmented arch with boot loop was used to control rotation and torque of the canine during its distalization. Once these three teeth were in the arch, treatment was finished in the usual manner. For esthetic improvement, gingivoplasty was performed in the maxillary arch. Eighteen-month follow-up showed that orthodontic treatment allowed preservation of the natural teeth, the contour of gingival support, and avoidance of prosthetic rehabilitation, reestablishing the patient’s esthetics and function, with satisfactory stability.

The purpose of the study was to determine the relationship between the parameters of the facial and brain bones of the skull and the structures of the posterior cranial fossa. The most important area of medical craniology remains the complex study of the typical variability of skull structures and formations and the regularity of their interrelationships in general. These include the posterior fossa with its brain regions and vascular communications. The morphology of the posterior fossa was studied on 13 passport turtles of adults from the collection of the fundamental museum of the Department of Clinical Anatomy, Anatomy and Operative Surgery of the Dnipro State Medical University. To solve the problems, a complex of craniometric methods was used. Craniometric studies of the posterior cranial fossa, the base of the skull, were performed with a thick compass with a millimetre scale and a technical calliper with a ﬁ ssion price of 0.01 mm, according to the standard craniology procedure. For statistical processing of data obtained as a result of craniometry the method of complex statistical analysis is applied, which includes modern methods of mathematical analysis: variation, correlation, factor and regression. Statistical analysis of the posterior fossa showed no signiﬁ cant gender and age diﬀ erences. The obtained data can be used both in theoretical medicine and in practical medicine, in particular in neurosurgery, to determine the volume of the posterior cranial fossa by the external size of the facial and cerebral regions of the skull. In our work, measurements were made of the skeletal structures of the posterior cranial fossa in the plane of the Frankfurt horizontal along the external dimensions of the facial and cerebral areas of the skull. The morphometric traits of «close» posterior cranial fossa (posterior cranial fossa) have been highlighted as increasing the ratio of the brain matter volume of the posterior cranial fossa to its bone volume. Craniometrically, the volume of the posterior cranial fossa has been determined to be between 110 and 218 cm3, averaging 158 cm3 with a statistical deviation of 19.14. The volume of the posterior cranial fossa in adults ranges from 140 to 230 cm3, with an average of 178 cm3. The posterior fossa volume of 178 cm3 is an indication of a «close» posterior cranial fossa. Studies of the correlation between the facial and posterior cranial lobes have shown that the posterior fossa correlates to varying degrees with individual facial size. As a result of research, V truncated cone, V ellipsoid and V cut of ball were determined. The V ellipsoid ranged from a minimum of 138,662 to a maximum of 225,688 cm3, V truncated cone from 111,562 to 169,455 cm3; the V cut of the ball from 83,694 to 192,06 cm3.

La puesta en marcha de cualquier actividad científica o académica supone la movilización de recursos económicos. La realización de investigaciones, la práctica de la enseñanza, la publicación de resultados, o la manutención de aquellos encargados de estas tareas, tanto como las oportunidades laborales que se les presentan en un determinado momento, dependen de la disponibilidad de fondos. Aun cuando diversos factores de índole general, como el contexto político más amplio, las cambiantes modas intelectuales o el clima ideológico en un determinado momento, inciden en la forma en que los científicos sociales desarrollan sus tareas, las condiciones más inmediatas de trabajo en que deben formular sus ideas y apuestas intelectuales –que pueden suponer (o no) algo tan básico y determinante como la posibilidad de acceder a puestos de tiempo completo– son determinantes.

Published: March 2023

Artikel ini membahas tentang tafsiran secara aqidah pada QS. al-Nisa/4:14 yang menjelaskan perihal neraka. Dalam artikel ini terdapat beberapa topik penting yang akan menjadi fokus bahasan yaitu, pertama adalah kajian tehadap ayat secara kosakata, keterkaitan dengan dalil lain dan penafsiran ulama, kedua adalah deskripsi kandungan aqidah dalam QS. al-Nisa/4:14. Oleh karena itu maka perlu kiranya menjelaskan hal-hal tersebut agar tidak menimbulkan kekeliruan dalam memahami ayat tersebut. Pengkajian masalah ini dilakukan dengan cara melakukan kajian pustaka dengan pendekatan kebahasaan dan pendekatan ilmu tafsir. Maka kesimpulannya adalah terjadi perbedaan pendapat dikalangan ulama tafsir dalam memahami dan menjelaskan ayat tersebut, ada ulama yang lebih cenderung kepada kemaksiatan, baik itu bentuk siksaan dan bentuk maksiat, ada ulama yang menafsirkan bahwa ayat tersebut berbicara tentang kekufuran terhadap syariat, dan ada ulama cenderung menafsirkan bahwa ayat tersebut mengandung perintah tidak boleh merubah ketetapan Allah swt.
