Mapping Architectural White Marble Use in Roman Italy: A Quantitative Study of Archaeometric Provenance Data
Authors: Taelman Devi 
Published: November 2024

Abstract

This paper presents a quantitative analysis of the distribution of white marble for architectural purposes in Roman Italy between 200 BCE and 500 CE. Through the analysis of a comprehensive dataset of 1,582 archaeometrically provenanced marble artefacts from 42 sites, this study addresses chronological trends and regional patterns in the use of white marble sources across Italy. The study shows significant differences in marble sourcing between Imperial Rome and smaller urban centres, reflecting two supply systems: a state-directed system for major public projects and a market-driven system for regional elite initiatives. While Carrara marble was the preferred choice in imperial and state projects, at least until the end of the second century CE, local elites in other areas of Italy selected material according to economic and logistical considerations. Outside Rome, Carrara and Proconnesian marble emerged as the most commonly applied white marble for architecture, although with regional and temporal distinctions in their relative importance. Carrara dominated southern Italy until the end of the second century CE, while Proconnesian marble was the most applied architectural white marble already in the first and second centuries CE. From the third century CE, we see that Proconnesian marble gained importance throughout Italy and surpassed Carrara.
Temperature Modulation of Cryoanalgesia for Pain Control in Irreversible Pulpitis: a randomized clinical trial
Authors: Gomez Gonzalo 
Published: November 2024

Abstract

Objetives:This prospective, randomized clinical trial aimed to evaluate the efficacy of pulpal anesthesia in pain control during endodontic procedures by comparing administration of 3% mepivacaine at refrigerated temperature to 3% mepivacaine at room temperature in teeth diagnosed with irreversible pulpitis. The null hypothesis posited no difference between the two types of this local anesthetic.
Materials and Methods:Twenty-six patients diagnosed with irreversible pulpitis of teeth were randomly distributed in two groups. Group 1 received 3% mepivacaine at room temperature, while Group 2 received 3% mepivacaine at 5°C. Preoperative variables were assessed, including pulp and periapical diagnosis, tooth type, pain levels, and anxiety level. Following administration of 3.6ml of local anesthesia, treatment commenced. Pain experienced during injection and pulpectomy were recorded. Fisher's exact test was employed to analyze preoperative factors and anesthetic success, with statistical significance set at p<0.05.
Results:The study findings revealed statistical differences in the success rate of anesthesia between the two groups. Group 2, which received mepivacaine at 5°C, exhibited an 80% higher success rate than Group I, which received mepivacaine at room temperature (20%). None of the preoperative variables demonstrated a significant correlation with anesthetic success.
Conclusion: Within the constraints of this clinical trial, it can be inferred that lowering the temperature of plain 3% mepivacaine from room temperature to 5°C enhances the success rate in pain management during treatment.
Clinical Relevance This article reports on a randomized clinical trial demonstrating that cooling 3% mepivacaine to 5°C significantly improves anesthetic success and pain management in cases of irreversible pulpitis during endodontic procedures.

Effect of Crack Geometry and Bedding Angle on the Cracking Processes in Composite Layered Rocks with Flaws
Authors: Zhao TENGYUAN 
Published: November 2024

Abstract

Composite layered rocks are widespread geological formations commonly subjected to engineering activities such as mining, tunneling, and petroleum extraction. However, due to the inherent heterogeneity and engineering disturbances, these rocks commonly exhibit local fractures and exist in pre-cracked states, posing a significant threat to the stability of rocks. Therefore, studying the mechanical behavior and cracking mechanism of composite layered rocks with pre-existing cracks holds significant importance. In this study, we modeled a series of composite layered rocks with double pre-existing cracks by considering variations in crack lengths, crack angles, and bedding angles. Numerical simulations were performed using the Rock Failure Process Analysis (RFPA) code. Under uniaxial compression simulation, we explored the processes of crack initiation, propagation, and coalescence under various crack geometries and bedding angles. The corresponding uniaxial compressive strength (UCS) and the rock bridge damage were also discussed. Our results indicate that crack length significantly reduces the strength of layered rocks, while increasing crack angle helps mitigate this reduction. Crack initiation locations and types are influenced by both crack length and crack angle, with the latter also influencing the rock bridge failure that is primarily characterized by vertical microcracks. Moreover, bedding angle also significantly affects crack initiation and propagation, with crack propagation often accompanied by bedding failure. As the bedding angle increases, bedding crack initiation becomes more frequent. Finally, the direct shear crack coalescence is more prevalent when α ≤ 30°, while the core-like crack coalescence is more common when α ≥ 45°.

Aim: to determine the effectiveness of primary treatment of patients with ovarian cancer of stages IA–IIA.Material and Methods. The study included 336 (100 %) patients with histologically confrmed ovarian cancer of stages IA–IIA, who were treated at the Primorsky Regional Oncology Center from 2004 to 2021. The overall survival (s) and progression-free survival (PFS) were analyzed depending on clinical and morphological factors: histological type of cancer, BRCA1/2 mutation, profle of the clinic where surgical treatment was performed, surgical staging and chemotherapy option. The examination for a mutation in the BRCA1/2 gene was performed by a new generation sequencing method. The data were statistically processed using the IBM SPSS Statistics 26 program.Results. The average age of patients with stage IA–IIA ovarian cancer was 52.12 ± 12.13 years. Statistically signifcantly higher survival rates were in patients with histological tumor type low-grade serous carcinoma compared with high-grade serous carcinoma (S: p=0.010 and IBP: p=0.020), with surgical treatment in specialized hospitals compared with patients operated in gynecological hospitals (s: p=0.040 and IBP: p=0.020), during adequate surgical staging (OV: p=0.008 and IBP: p=0.010), during treatment with platinum and taxanes (OV: p=0.001 and IBP: p=0.001).Conclusion. It was shown that about 30 % of patients with stage IA–IIA ovarian cancer in Primorsky Krai received primary surgical treatment in non-specialized hospitals, which increased the risk of progression and death by 1.7 times. A low percentage of adequate surgical staging was noted (12.5 %). Adjuvant chemotherapy with platinum and non-oxane agents worsened the prognosis of the disease. Patients with low-grade serous carcinoma had a more favorable prognosis (by 60 %). There was no statistically signifcant effect of the presence of a mutation in the BRCA1/2 genes on survival rates.

The aim of study is to conduct in vivo biological testing of titanium nickelide samples modifed with Ag/Pt or AuAg/Pt flm heterostructures in comparison with the bare carrier.Material and Methods. Titanium nickelide plates modifed with flm heterostructures made of noble metals and the laboratory mini-pigs used for in vivo tests were the objects of the study. To form flm structures on titanium nickelide samples, the physical gasphase deposition methods: ion plasma deposition (IPD) and thermal (PVD) sputtering were used. The Ag/ Pt or AuAg/Pt heterostructures were characterized by X-ray diffraction and scanning microscopy methods.Results. The biocompatibility of implants before (TiNi, control) and after (Ag/Pt/TiNi and AuAg/Pt/TiNi) modifcation with flm heterostructures was tested in in-vivo experiments on a laboratory animal (mini-pig). General toxic reactions of the body to the injected samples were absent. A comparative macroscopic and histological analysis of the condition of peri-implant tissues after 39 days of implantation was performed. The connective tissue capsule around the TiNi sample revealed the presence of a certain number of lymphocytes, eosinophils and macrophages, but these indicators decrease in the order of TiNi > AuAg/Pt/TiNi > Ag/Pt/TiNi.Conclusion. The positive effect of modifying the titanium nickelide surfaces with noble metal heterostructures on the biocompatibility of metal implants was demonstrated in an in vivo experiment.

Background. Compliance with principles of surgical oncology is necessary to choose effective treatment options for locally advanced rectal cancer (LARC).Objective: to show the basic surgical principles for LARC using a new option of complex therapy.Material and Methods. The basic surgical principles for LARC using a new option of complex therapy with polyradiomodifcation (local microwave hyperthermia + intrarectal administration of a polymer composition with Metronidazole) in combination with polychemotherapy (oral administration of Capecitabine + intravenous administration of Oxaliplatin) with concurrent prolonged hypofractionated radiation therapy were presented.Results. The treatment outcomes of the new option of complex neoadjuvant therapy with the compliance of surgical oncology principles were studied in 46 patients with LARC (T3cd-T4a N1c-2ab M0, CRM+, EMVI+). An analysis of the immediate outcomes showed that postoperative complications were diagnosed in only 4 (8.7 %) of 46 patients and no deaths were recorded. The local control was achieved: cancer recurrence was diagnosed in only 1 (2.2 %) and distant metastases in 4 (8.7 %) of patients. The 5-year recurrence-free survival rate in these patients was signifcantly higher than that observed in patients who received conventionally fractionated radiotherapy in combination with Capecitabine (81.0 vs 56.8 %, p=0.02). The improvement of results was achieved both by adhering to the principles of surgical oncology and increasing the radiosensitivity of the tumor: pathologic complete response was achieved in 35 (76.1 %) patients. This made it possible to perform sphincter-preserving surgeries in 71.7 % (33 out of 46) patients and in 66.7 % (18 out of 27) with lower-ampullary cancer.Conclusion. The use of a new method of complex therapy for LARC and compliance with the basic principles of surgical oncology allowed the improvement of long-term treatment outcomes by achieving local control of the tumor, contributing to the expansion of indications for performing sphincter-preservingsurgeries.

Rakstā mēģināts izsekot vienam no zvirbuļa nosaukumiem – leksēmai žīgurs izplatības un cilmes aspektā. Apelatīvs žīgurs 20. gs. otrajā pusē sastopams kompaktā areālā Vidzemes ziemeļaustrumos un Latgales ziemeļos. 19. un 20. gs. leksikogrāfiskajos avotos ietvertā ģeolingvistiskā informācija paplašina izplatības areālu rietumu un dienvidrietumu virzienā. Leksēma žīgurs ietverta Jakoba Langes un Karla Kristiana Ulmaņa vārdnīcās. Taču J. Langes vārdnīcā ar šo vārdu tiek apzīmēts stārķis, bet K. K. Ulmaņa vārdnīcā – zvirbulis.
Arī onīms Žīgurs (arī daudzskaitlī – Žīguri) rāda to pašu paplašināto apelatīva žīgurs izplatības areālu. Onīms Sigur ir atrodams jau 1638. gada Vidzemes arklu revīziju materiālos sešās vietās. 20.-21. gs. tas ir ciema, viensētu, krogu, ezeru, lauku, pļavu u. c. nosaukums. Tas zināms arī kā uzvārds.
Par leksēmas žīgurs cilmi ir interesējušies valodnieki kopš 19. gs. otrās puses. Pirmais, kurš ir izvirzījis hipotēzi par prūšu singuris ‘dadzītis’ saistību ar latviešu žīgurs, ir F. Fiks. Taču leksēmas žīgurs izplatības areāls nav raksturīgs prūsismiem. J. Endzelīns atsevišķi nedod apelatīva žīgurs cilmi, taču kopvalodas putna nosaukuma zvirbulis sakarā norāda, ka tas varētu būt radies saknes virb- (poļu wróbel, krievu воробей) un vārdu ar z- resp. ž- (latv. zvĩgurs, zvipuris, žīgurs) kontaminācijas rezultātā.

Objetivo: Avaliar o perfil nutricional e consumo alimentar de risco e proteção para doenças crônicas não transmissíveis em universitários da área de saúde. Metodologia: Estudo transversal, envolvendo 126 universitários dos cursos da área de saúde do Centro Acadêmico de Vitória-UFPE, de ambos os sexos e maiores de 18 anos. Na pesquisa foram obtidas informações sociodemográfica, antropométrica, de estilo de vida e consumo alimentar. O consumo alimentar foi avaliado por meio do questionário de frequência alimentar com mensuração convertida em escores. Resultados: Da amostra analisada, a maioria apresentou estado nutricional de normalidade (69,8% eutróficos; 8,7% baixo peso; 17,5% sobrepeso; 4% obesidade), no entanto evidenciou-se um alto nível de sedentarismo entre os estudantes. Os escores de consumo sobre alimentos protetores e de risco para doenças crônicas não transmissíveis indicaram uma tendência a um maior consumo de alimentos de proteção (p=0,251). Conclusão: Apesar dos universitários demostrarem um estado nutricional adequado, observou-se que o consumo de alimentos considerados protetores para doenças crônicas não foi um achado significativo neste estudo. Verifica-se a necessidade da adoção de programas da saúde na universidade, no intuito de incentivar a prática regular de atividade física e bons hábitos alimentares.

The Role of Managerial Ability in Bribery and Operational Performance: Evidence from FCPA Violations
Authors: Du Pon Adam W. , Scheetz Andrea M. , Zhang Zhenyu 
Published: November 2024

ABSTRACT
This study examines factors influencing bribery activities that violate the United States’ Foreign Corrupt Practices Act (FCPA) of 1977 and assesses the operational consequences of such activities. Leveraging the managerial power approach and supported by the Peter Principle, we investigate how managerial ability associates with bribery. The results suggest that bribery occurs in firms overseen by managers of reasonably high ability, but the highest ability managers deter such corrupt practices. We also find that bribery substitutes for managerial ability in the pursuit of sales goals and that bribery negates the positive impact of managerial ability on future operational performance. Cross-sectional tests indicate these nonlinear results are most pronounced among firms with Big 4 auditors and that FCPA violations are associated with the purpose of sale generation.

Published: November 2024

Abstract
This article explores how global citizenship can be seen in the practices of science education in the context of international education policy and Finnish school and teacher education, with a focus on scientific literacy and sustainability education for promoting a sustainable future. Possibilities of science education to promote sustainability are discussed through teaching examples based on socio-scientific approaches. In addition, transformative science education for sustainability is regarded through competence development taking into account different knowledge dimensions. Solving problems however requires not only knowledge but also communicative and strategic and speculative activity. Thus, education must emphasize the main visions of scientific literacy and transdisciplinary perspectives proposed in the literature, supporting students to understand society and everyday socio-scientific challenges from the local to global level and to deal with differing scientific results and uncertain information. Our article presents findings and conclusions that provide opportunities for further work and provide insights into science and educational sustainability practice.
