Comparison of Fracture Resistance Between Immediate and Delayed Composite Restorations With or Without Fiber After Root Canal Treatment: a Field-Emission Scanning Electron Microscope Study
No full textBackground: This study aimed to evaluate the fracture resistance of immediate and delayed restorations after root canal treatment (RCT). Methods: Sixty human intact premolar teeth were used. Teeth were prepared disto-occlusally. After RCT, teeth were randomly divided into two groups according to restoration times (immediate or 3 months delayed). The three month delay was imitated by thermomechanical aging. Then, samples were divided into six subgroups (n = 10). While I (Composite resin), II (Flowable bulk-fill) and III (Ribbond+Flowable bulk-fill) were restored immediately, Groups IV, V and VI were restored with temporary filling material and stored in distilled. After subjected to thermo-cycling (2,500 cycles, 5-55 degrees C) and exposed to 60,000 cycles in a chewing simulator, Group IV (Composite resin), V (Flowable bulk-fill) and VI (Ribbond+Flowable bulk-fill) were restored. All of the teeth were fractured on the universal testing machine. Failure modes were analyzed using scanning electron microscope. Data were analyzed using the Shapiro-Wilk and two-way ANOVA tests (p 0.05). Most of the repairable fractures were seen in Groups I and II. Conclusion: Delaying the permanent restorations of teeth for 3 months did not affect fracture resistance. However, it was suggested to avoid delaying restorations for obtaining repairable surfaces.Science Citation Index Expande
Fathers' Interactions With Their 3-6 Year-Old Children: an Examination From the Perspective of Emotional Abuse
No full textEmotional abuse is the behavior that occurs when caregivers consistently fail to do what they should do; prevents the fulfillment of children's basic psychological needs, significantly affects children's behavioral, cognitive, emotional and psychosocial development; and causes them to feel worthless or unloved. Paternalism and emotional abuse are complex and interconnected issues that have attracted significant attention in the literature. The present study examines the emotional abuse perpetrated by fathers with children aged 3-6 years to their children. The study was conducted in the instrumental case study model, one of the qualitative research designs. The study includes 18 fathers with different levels of education determined by snowball sampling, one of the non-probability sampling methods. The data collected with semi-structured interview questions obtained through expert opinions and pilot study were analyzed by content analysis method. The findings are revealed in three main sections: Father-Child Relationships and Interactions, Fathers' Approach to Undesirable Behaviors and Fathers' Disciplinary Method. The results showed that fathers, in addition to positive discipline practices such as explanation and modeling, mostly exhibit negative behaviors such as reward-punishment use, authoritarian attitude, intimidation, stern warnings, and violence, which can lead to emotional abuse when applied continuously. It is thought that training programs and awareness studies should be designed to develop fathers' parenting skills and prevent emotional abuse. In addition, considering the scarcity of studies specifically targeting fathers, research on emotional abuse by fathers should also be conducted.Okan UniversityWe would like to thank all the fathers who voluntarily participated in our research.Social Science Citation Inde
Enhancing Solar Greenhouse Efficiency Through the Integration of Phase Change Materials: Thermal Regulation and Sustainable Crop Growth
No full textChibani, Atef/0000-0002-5861-7498; Agyekum, Ephraim Bonah/0000-0002-6947-4349The increased request for sustainable agricultural practices in response to climate change requires inventions in greenhouse design and operation. This review inspects scientific investigations that explore how solar greenhouses utilise phase change materials (PCMs) to improve thermal regulation, decrease expenses, and support crop growth. Also, it examines the matter of temperature instability in traditional greenhouses, as fluctuated temperatures would negatively impact plant health and crop production. Experimental research on PCMs has led to the development of a new thermal energy storage system, which has been analysed for its competence. The outcomes of this review specify that greenhouse temperatures can increase meaningfully during crucial nighttime hours when PCMs are utilised, with a temperature difference ranges between 1 degrees C to 2 degrees C greater than those in standard greenhouses. Also, the integration of PCMs can reduce the daily temperature fluctuation by 3 degrees C to 5 degrees C, enhancing temperature control. Accordingly, it can be said that the incorporation of PCMs within solar greenhouses can enhance the environmental conditions of crops besides boosting the thermal efficacy, contributing to agricultural sustainability. Finally, this review presents an operational strategy to transform greenhouse functionality by enhancing the energy competence and climate resilience. In turn, these systems could revolutionize greenhouse operations and address global food security challenges.Science Citation Index Expande
Micromobility Perspectives From Engineering, Urban Planning, Health Sciences and Social Sciences Introduction
No full textE-scooters, which started to gain popularity especially among the youth before the COVID-19 pandemic and saw a rapid increase in use due to the pandemic, have significantly contributed to the spread of the micromobility concept and its adoption by wider segments of the public. In general, transportation systems that use small, individual vehicles capable of traveling at speeds below25 km/h are considered micromobility. Among micromobility systems, there are different subtypes, such as bicycles, skates, and skateboards powered by human energy; segways and unicycles powered by electricity; and e-bikes and e-scooters that use a combination of human and electric energy. Significant developments in both the demand for micromobility and micromobility services are expected in the coming years.Book Citation Index – Social Sciences & Humanities - Book Citation Index – Scienc
Mathematical Analysis of Chickenpox Population Dynamics Unveiling the Impact of Booster in Enhancing Recovery of Infected Individuals
No full textChickenpox (varicella) is a highly transmissible infection primarily caused by a herpes virus called Varicella Zoster and is a commonly reported childhood disease. In this paper, a deterministic nonlinear model was adapted to investigate the dynamics of chickenpox that incorporates intervention in the form of isolation and treatment. In the mathematical analysis part, the positivity and boundedness of the solution have been ascertained, existence of disease equilibria has also been ascertained, which shows that the model consists of two equilibriums, the DFE (disease-free equilibrium point) and EE (endemic equilibrium point). The effective reproduction number has been computed using the next-generation operator method and the basic reproduction number has been computed by setting all the associated effective reproduction number to zero. The DFE was found to be both (globally and locally asymptotically stable) if R-c < 1 and the global stability of disease-free equilibrium point has been proven using the comparison method. Global asymptotic stability of EEP(endemic equilibrium point) has been ascertained using the nonlinear Lyapunov function of the Go-Volterra type, which reveals that, the EE is globally asymptotically stable if the basic reproduction number is greater than unity and omega = psi(1) = psi (2) = delta(1) = delta(2) = 0 . Sensitivity analysis shows that natural recovery and isolation are very sensitive in reducing the control reproduction number and effective contact rate is very sensitive in increasing the effective reproduction number. In the numerical simulation part, the section confirmed the analytical results and further, shows that the natural recovery booster is a vital parameter that helps greatly in the healing process of chickenpox patients. The proposed model also reveals that the isolation and treatment rate of infected individuals are very important parameters in controlling chickenpox in society. We recommend that immunity boosters and isolation be prioritized in controlling chickenpox in the population.Emerging Sources Citation Inde

For Sets of β+Decaying Radioisotopes of the Same Element, the Highest Initial Kinetic Energy of the Emitted Positron Falls Off Straightly With Increasing Atomic Mass Number a
No full textYarman, Tolga/0000-0003-3209-2264;Earlier, we had presented a systematization of beta+-decaying nuclei,1 where the interrelation between the decay half-life T and the highest initial kinetic energy epsilon of the positron at the instant it is emitted (if the neutrino energy is assumed to be zero) was transcribed through the formula T similar to 1/epsilon. Herein, we reveal that the highest initial kinetic energy epsilon linearly decreases with respect to the increasing atomic mass number A for each of the given sets of beta+-decaying radioisotopes of the same element. This, combined with the foregoing relationship, means a more stable beta+-decaying nucleus, or the same, a longer decay half-life with respect to increasing A. All this, in turn, leads, as a first approximation, to an easily memorizable expression of the rate of change Delta T/T of the half-life versus the change Delta A in the form of Delta T/T similar to Delta A. Using this relationship, and putting aside possible anomalies, one can predict within an acceptable accuracy the half-lives of beta+-decaying nuclei that could not be measured until now.Science Citation Index Expande

No full textAkbulut, Ahmet Alperen/0000-0002-3273-6632; Karaman-Demirel, Aysenur/0000-0001-7737-8042Purpose: Although burnout among audiologists has been studied in various countries, there is no research yet that examines this issue in T & uuml;rkiye, where working conditions and sociodemographic factors may differ from those in other countries. Considering the unique working conditions and sociodemographic factors, this study aimed to investigate the burnout levels of Turkish audiologists. Additionally, this study will explore the impact of various sociodemographic variables on burnout, work-related quality of life, and depression to gain a deeper understanding of the specific challenges faced by audiologists in T & uuml;rkiye. Method: A total of 193 audiologists, with a median age of 27 (interquartile range: 25-29) years, working in different working areas, such as clinical practice, academic institutions, rehabilitation centers, and amplification services in T & uuml;rkiye, were included. Audiologists were invited to participate in this study via several online forums and hospital notice boards. All participants completed the sociodemographic data form and then the Maslach Burnout Inventory (MBI), Work- Related Quality of Life Scale (WRQoL), and Beck Depression Inventory (BDI). Results: Differences between MBI, WRQoL, and BDI scores were analyzed according to gender, level of education, area of work, and title of audiologist. There are significant differences in the subscale scores of the MBI and WRQoL scales and in the BDI scores between groups according to gender, education, and area of work. There are also significant differences in BDI scores according to title. There is a significant correlation between the MBI, WRQoL, and BDI scores of audiologists. Conclusions: This study represents the initial exploration of burnout, quality of work life, and depression levels among audiologists employed in T & uuml;rkiye. A low quality of work life can increase the risk of burnout and depression. Enhancements in the work environment can lessen burnout and depression while also improving employees' general quality of life.Science Citation Index Expande
