Curves Along Lorentzian Submersions
Authors: TÜKEL Gözde ÖZKAN 
Published: July 2023

Abstract
We explore the impact of curve theory on the characterization of Lorentzian submersions which are special cases of semi-Riemannian submersions. We firstly give a classification of curves according to their causal character along a Lorentzian submersion. Then, we investigate the effects of certain curves, specifically the non-null Frenet curve, the non-null circle, the non-null helix, and the geodesic, under a Lorentzian submersion, and we seek their geometric meaning. Finally, we examine the situation where a Cartan-framed lightlike curve is carried from the total manifold to the base manifold through a Lorentzian submersion.

Influence of Primordial Black Holes on Cosmic Reionization through Semi-Analytical Modelling
Authors: Jhurani Krish , Gunhal Pranav 
Published: July 2023

Abstract

This research addresses the influence of Primordial Black Holes (PBHs) on cosmic reionization, using a robust semi-analytical model. This model encapsulates cosmological theory, PBH physics, and radiative transfer, with a lognormal PBH mass function as the fulcrum, with the mean PBH mass set at 30 solar masses and the fraction of dark matter in PBHs ( f_PBH) varied from 1.26 to 10. We also adopt a standard thin-disk accretion model and a one-dimensional radiative transfer code for a comprehensive depiction of cosmic reionization under the influence of PBHs. Our major findings reveal an inverse relationship between PBH mass and ionizing efficiency. For instance, when the mean PBH mass is 10 solar masses, and f_PBH is 0.1, the resulting ionizing efficiency is approximately 0.25, which drops to 0.15 with a mean PBH mass of 50 solar masses. However, with f_PBH nearing unity, even large PBHs (mean mass of 100 solar masses) can achieve an ionizing efficiency close to 0.2. The ionization history indicates that for a mean PBH mass of 10 solar masses and f_PBH at 0.01, rapid ionization commences at z=12.5±0.5 and concludes at z=9±0.5. Conversely, with a larger PBH mass of 100 solar masses and f_PBH at 0.01, reionization initiates later, at z=10.8±0.4. Our two-point correlation function analysis unveils the formation of ionized bubbles with an initial size of approximately 10 Mpc at z=7.5±0.5 for an f_PBH of 0.01, expanding to 20 Mpc by the end of reionization. With f_PBH of 0.1, larger bubbles form, starting at approximately 15 Mpc and reaching 30 Mpc by reionization's end. In conclusion, PBHs significantly influence cosmic reionization, with PBH mass and their contribution to dark matter modulating this impact.

Abstract
Background: This study aims to show the effect of full immersion virtual reality-based rehabilitation (VR) using commercial gaming software on upper limb motor recovery in chronic ischemic stroke patients with hemiparesis.
Case Presentation: This is a case series study in stroke patients who come for treatment at the Medical Rehabilitation Clinic of Cipto Mangunkusumo General Hospital under University of Indonesia. Patients’ baseline data were examined in the form of Fugl-Meyer Upper Extremity (FM-UE), Chedoke Arm, and Hand Activity Inventory (CAHAI), and Brain Derived Neurotrophic Factor (BDNF) scores. Patients received physical rehabilitation treatment for 3 times a week, 30 minutes per session for 6 weeks using Occulus Quest with Beat Saber and Hand Physics Lab software. Post intervention, FM-UE, CAHAI and BDNF data were collected. The study subjects consisted of 2 men and 3 women with an age range of 45 – 59 years, 4 left hemiparesis and 1 right hemiparesis, Brunnstrom IV – VI. After the intervention was given, there was an increase in all three parameters FM-UE (median difference: 2, min – max: 1 – 19, MCID: 5.25), CAHAI (median difference: 2, min – max: 1-18, MCID: 6 .3), and BDNF (median difference: 16.68, min – max: 9.76 - 46.8).
Conclusion: Full immersion virtual reality-based rehabilitation using commercial gaming software shows a promising positive improvement phenomenon in upper limb motor recovery in chronic ischemic stroke patients after 6 weeks of intervention.

Published: July 2023

Abstract
Carbon nanoparticles are gaining much importance in the contemporary world. Among which carbon nanocones have wide range of acceptance in the field of nanotechnology due to its effective properties and applications. Nanocones, also known as nanohorns are carbon networks which are planar in structure and has majority of hexagonal faces along with some non-hexagonal faces, which are most commonly pentagons. Nanocones which include pentagons in their structure can be referred to as adjacently or non-adjacently configured pentagonal structure of nanocones. Carbon nanocones possess properties like specific surface area, high yield, high chemical stability, high purity, low toxicities, exceptional catalytic properties, superior porosity, and good conductivity compared to other carbon nanostructures. These exceptional properties help nanocones to be a good replacement for carbon nanotube. Also nanocones have secured its place in fields like electrochemical sensing or biosensing, biofuel cell, as an electrode material, supercapacitor, gas storage device and biomedical applications. The information entropy was introduced to analyse and quantify the complexity of data and information transmission. It is applied to study the complexity and the quantum chemical electron densities of molecular structures. Later, the idea of graph entropy came into role to characterise the complexity of graphs. The concept of graph entropy is to assign a probablity function to the edges in the chemical graph using the topological descriptor. In this work, the degree based descriptors and the corresponding graph entropies for the adjacently and non-adjacently configured pentagonal structure of nanocones are determined.

Authors: Nawkhass Maher A. , Sulaiman Nejmaddin A. 
Published: July 2023

Abstract
Ranking fuzzy numbers is essential to descriptive decision-making and several other fuzzy systems and applications. Numerous techniques have been put forth to rank fuzzy numbers. It has been demonstrated that each of these approaches occasionally yields findings that are counterintuitive. The aim of this studies can be factors such as: firstly, Willingness to improve manufacturing production. Secondly, to minimize production time (negated iteration). Finally, the aspiration to discover new linear fuzzy script The study of “Fuzzy Linear Fractional Programming” FLFP problems with “trapezoidal fuzzy numbers” has been addressed in this research, where the constraints are actual numbers and the objective functions are fuzzy numbers. Obtaining the fuzzy optimum solution with unconstrained variables and parameters has been made possible in this study by the introduction of a modern, effective strategy for the FLFP problems. The newly employed transformation methodology is similarly based on the suggested method of crisp linear fractional programming foundation. To get an ideal answer, a computational method has been provided. A real-world example has been given to show the effectiveness of our suggested methodology.

Published: July 2023

Background:One of the important materials needed for root treatment is the sealers. They fill the space between the gutta and the canal walls and create a suitable seal to prevent the colonization of oral microorganisms in the peri-apical tissues and inside the canal space.Aim:The aim of this study was to prepare and test the cell biocompatibility of a new polycaprolactone-based endodontics sealer in comparison to AH plus sealer against dental pulp stem cells.Methods:MTT assay was used to evaluate the cytotoxicity.Results:The results showed that AH plus showed moderate cytotoxicity effects against cells (the number of living cells was 49.45 ± 10.56%). However, for the new sealer, the number of living cells was ≥ 80% (81% ± 4.11). Thus, the sample was non-cytotoxic against tested cells.Conclusion:More investigations are needed on the new sealer to validate its biocompatibility and usefulness.
Necessity of Antibiotic usage after Simple Tooth Extraction in Patient with Healthy Systemic Condition in Herat, Afghanistan
Authors: Erfan Ozair , Khan Manizha , Taka Gulbahar 
Published: July 2023

Background/Purpose:
Over-intake of antibiotics like amoxicillin, penicillin, ceftriaxone, gentamycin, ampiclox, metronidazole and last but not least, tetracycline is a practical hazard in aid-supported settings such as Afghanistan where not only one can get access to them easily, but also they are generously being prescribed without consideration for necessity or side effects. Prescribing antibiotics after simple tooth extraction has remained a questionable topic in dental academia, especially in the third world countries. Among dental procedures, extraction is the most common procedure for the prescription of antibiotics. This study is aimed to determine the necessity of using antibiotics after simple tooth extraction in people with a normal systemic condition and establish its role in reducing pain and discomfort, swelling, and dry socket.

Materials and Methods:
This double-blinded RCT study was performed in two dental surgeries; Erfan Specialized Dental Clinic and Mena Oral and Dental Care Centre. In all 237 patients, selected systematically, randomized, tooth extraction was performed following the same protocols and materials before and after tooth extraction. Two types of prescriptions (one with antibiotics and one without antibiotics) were prepared in a box. After tooth extraction participants were asked to pick one prescription by chance. All data were collected and analyzed with the SPSS-25 program.

Results:
Among all participants 76.37% were female and 23.63% were male. Regarding reasons that led to tooth extraction, 43.04% of teeth were extracted due to profound caries, making it the most common reason followed by periodontitis 14.77% and root remnants 10.55%. Pain and discomfort peaked in the first 10 hours after extraction and gradually decreased up to 48 hours after extraction.
Swelling was observed 2.53% more in antibiotic users than 0.42% in those that didn’t take them and the p-value was significant <0.05. There is no obvious difference between antibiotic usage and dry socket formation, and the p-value was not significant (>0.05).

Conclusion:
Antibiotics are not necessary after simple tooth extractions in patients with a normal systemic condition, even in countries like Afghanistan where patients overuse antibiotics, nor do they have any role in reducing pain, swelling, and dry socket after simple extractions.

Background:Many current concepts about irrigation solutions have evolved over time; a historical perspective of irrigation solutions and the reasons for their introduction to endodontic treatment is required. The authors of this work believe that a large number of unrecognised published works from the 20thcentury need to be brought to light so that researchers can acquire some important hints and insights into how those solutions were developed and used in the past.In this paper, we investigate historical attempts to develop the optimal irrigation solution as well as the evolution of the scientific community's views on how to achieve this aim.Methods:A review of the literature related to irrigation solutions in endodontics was conducted using Scopus, Google Scholar, and Web of Science. Historical articles were identified through tracking citations of included articles and were obtainedviathe library of the University of Dundee.Results:Without the attempts of the past, we wouldn't be where we are today, including the role that several irrigation solutions played in endodontics before they were phased out. The observation that none of the currently available solutions had all of the properties that would make them ideal when used on their own led to the conception of the notion of mixing multiple types of irrigation systems, an idea that has since become widely popular.Conclusion:This study suggests pursuing two lines of inquiry: first, finding the best companion to sodium hypochlorite that produces no undesirable reaction precipitates; and second, maintaining the effort toward the development of a single irrigation solution that can effectively disinfect the canal without endangering the vital tissues. In general, and for some different possible combinations, there appears to be some light at the end of the tunnel, which is something that will hopefully be uncovered in the not-too-distant future.

Background
The COVID-19 pandemic has shed light on fractures in health care systems worldwide and continues to have a significant impact, particularly in relation to the health care workforce. Frontline staff have been exposed to unprecedented strain, and delivering care during the pandemic has affected their safety, mental health, and well-being.

Objective
This study aimed to explore the experiences of health care workers (HCWs) delivering care in the United Kingdom during the COVID-19 pandemic to understand their well-being needs, experiences, and strategies used to maintain well-being (at individual and organizational levels).

Methods
We analyzed 94 telephone interviews with HCWs and 2000 tweets about HCWs’ mental health during the first year of the COVID-19 pandemic.

Results
The results were grouped under 6 themes: redeployment, clinical work, and sense of duty; well-being support and HCW’s coping strategies; negative mental health effects; organizational support; social network and support; and public and government support.

Conclusions
These findings demonstrate the need for open conversations, where staff’s well-being needs and the strategies they adopted can be shared and encouraged, rather than implementing top-down psychological interventions alone. At the macro level, the findings also highlighted the impact on HCW’s well-being of public and government support as well as the need to ensure protection through personal protective equipment, testing, and vaccines for frontline workers.

Published: July 2023

Objectives: In this trial, It has been investigated whether pertuzumab, when added to adjuvant trastuzumab and chemotherapy, improves outcomes among patients with HER2-positive early breast cancer in compares to patients who received only Herceptin
Methods: After surgery and central HER2-positive confirmation, about randomly 220 patients assigned with high-risk HER2-positive, operable breast cancer to received Anthracycline based chemotherapy 3 cycles fallowed by Taxotere 3 + either pertuzumab + hercetin 3 or standard adjuvant Herceptin alone, 17 cycles in 1 year. The patients were followed up for 3 years.
Results: Results were indicated that about 50% of the patients who were randomly assigned to arm A received pertuzumab+Herceptin 3 cycles every 3 weeks (110 patients) and arm B 50% (110 patients) received Herceptin alone 17 cycles every 3 weeks. Disease recurrence occurred in 12 patients (10.9 %) in the pertuzumab group and 8 patients (7.2%) in the arm B group (hazard ratio, 0.81; 95% confidence interval [CI], 0.66 to 1.00; P=0.045). The estimates of the 3-year rates of invasive-disease-free survival were 89% in the pertuzumab+ herceptin group and 93% in the herceptin group. Heart failure, cardiac death, and cardiac dysfunction were infrequent in both treatment groups. Diarrhea of grade 3 or higher occurred almost exclusively during chemotherapy and it was more frequent with pertuzumab than with group B (7.9% vs. 2.8%).
Conclusions: The study showed that pertuzumab + Trastuzumab adjuvant in 3 cycles worse rates of invasive-disease-free survival among patients with HER2-positive, operable breast cancer in compares with classical trastuzumab alone in 17 cycles. Diarrhea was more common with pertuzumab than with classical Trastuzumab therapy.

DADOS PARA UMA LEITURA DO ATUAL SISTEMA DE ENSINO SUPERIOR E DE PESQUISA NA FRANÇA: ESTRATÉGIA, PROGRAMAÇÃO, AVALIAÇÃO E UNIDADES OPERACIONAIS
Authors: Baptista Tatiane Alves 
Published: July 2023

O artigo aborda o conjunto de mudanças ocorridas no sistema de educação superior e pesquisa francês visando uma caracterização geral da sua atual configuração. Para isso, faz a descrição dos principais processos de reconfiguração do sistema a partir da análise da atual legislação, identificando significativas mudanças no concernente à dimensão estratégica, à programação, ao financiamento, à operacionalização e à avaliação. Assim, destacam-se três esferas sistematicamente articuladas. Para entender as razões subjacentes a tais mudanças, o artigo recupera o contexto global de ajustes internacionais – especificamente o chamado New Management Programme (NPM), para, a partir tais evidências, situar o novo quadro cartográfico da educação superior na França. Concluindo que as transformações em andamento fazem parte, por um lado, de uma tendência global no setor, envolvendo elementos econômicos, a questão do modelo de financiamento público, a gestão de recursos humanos em uma lógica de competição e a sofisticação dos mecanismos de controle do trabalho acadêmico. Por outro lado, há mudanças também pelo prisma da ressignificação do papel das universidades enquanto protagonistas na produção de soluções inovadoras e de impacto socioeconômico. As duas tendências pesam sobremaneira para um dos pilares mais importantes das instituições de ensino superior e pesquisa, a saber, a questão da autonomia.

El mango es un fruto muy apetecido a nivel comercial que presenta un periodo de vida útil corto, sino se almacena y conserva correctamente. El objetivo de este estudio consistió en evaluar el efecto de diferentes concentraciones de L-arginina (Arg) y Ácido Ascórbico (Asc) en la conservación a vacío del mango Tommy mínimamente procesado. El mango fue cortado en rodajas de 3 a 4 mm, retirando el epicarpio y la semilla. Posteriormente, se distribuyeron en partes iguales de 200 g y cada muestra se sumergió durante 2 minutos en soluciones de: (Arg-25 mM, Arg-50 mM y Arg-100 Mm) y (Asc-0,25 %, Asc-0,50 % y Asc-1 %), finalmente se secaron a 27 °C ± 2 por 5 minutos, empacándose al vacío y se evaluó su almacenaje en cámara climática a 10 °C y 70 % HR durante 0, 3, 7, 13 y 21 días. Los parámetros fisicoquímicos analizados fueron: la firmeza como textura de corte, color y sólidos solubles. Los tratamientos Asc-1 %; y Arg-25mM, lograron obtener una textura 3 veces mayor hasta los 21 días de almacenamiento, por encima del tratamiento control. Los tratamientos que mantuvieron el color característico del mango sin oscurecimiento fueron Asc-0,25 %, Asc-0,50 % y Asc-1 %, contrario a lo evidenciado para los tratamientos con L-Arginina donde el oscurecimiento y pérdida de textura aumentaron a medida que aumentó su concentración. Los sólidos solubles (°BRIX), tuvieron diferencia de 3 °BRIX entre la fruta que no tuvo inmersión (11 °BRIX) y la fruta que fue sumergida en soluciones conservantes (8 °BRIX), no tuvo diferencias significativas de solidos durante el almacenamiento. Los tratamientos Asc-1 % y Asc-0,50 %, lograron conservar el color característico del mango fresco evitando la pérdida de textura hasta los 21 días de almacenamiento.
