Are hydrides under high pressure high temperature superconductors?

Contrary to the current consensus, I argue that the existing evidence for high temperature superconductivity in hydrides under high pressure is not compelling. I suggest that the focus of the field should urgently shift to establish unequivocally experimentally whether or not superconductivity in pressurized hydrides exists, instead of continuing to search for new materials that might show elusive signals of unproven superconductivity at ever higher temperatures. The implications of a negative finding for the theoretical understanding of superconductivity are discussed.
Physical and thermal properties of turmeric rhizomes

The physical and thermal properties of three varieties of turmeric rhizomes viz. BSR I, BSR II and Erode local were studied. BSR I had the highest primary finger length (82 mm) over the other varieties. The Erode variety showed higher weight for 1000 rhizomes. The bulk density, true density, moisture content, coefficient of friction, specific heat and thermal conductivity increased with increase in moisture content, for all the three varieties tested. Multiple regression equations were developed to predict all the physical and thermal properties of turmeric rhizomes as a function of moisture content.
Social networks of trust based on social values: An explanation of curvilinear relationships between generalized trust and democracy

ABSTRACT Analyses of data from the World Values Survey show that generalized trust in highly democratic societies is stable and strong, but it is also strong in highly authoritarian societies. The goal of this study is to specify the mechanism of the relationship between generalized trust and political institutions. I categorize generalized trust as two types: democratic trust and authoritarian trust. When a society features a mixture of democratic and authoritarian trust, generalized trust tends to be weaker because of conflicts between democratic and authoritarian values. As a result, with diffusing democratic values, generalized trust in a society will first be temporally weakened, but eventually it will strengthen.
An Evaluation Study of a Electronic Whiteboard System for Nursing Care in the Emergence Unit

The main objective of this research is to evaluate a task and alert management system denominated SHAVI (SHAred VIew), developed to be used by the Nursing team of the Emergency Unit of a University Hospital located in southern Brazil. The system was developed as a resource for managing patients clinical data and warning signs of clinical deterioration during urgency and emergency care. The research is characterized as exploratory and descriptive, with data collection carried out in the field with 21 participants, including students and professionals working in the emergency sector, through the application of a questionnaire consisting of 48 questions. The usability and user acceptance of the tool was mainly verified based on Nielsen’s Usability Heuristics and the Technology Acceptance Model. The evaluation and user participation contributes to identify problems and make corrections before putting the system into use, contributing to its adoption and acceptance.The evaluation reveled that the system has great potential for use and can be considered a safety mechanism for monitoring patients in the emergence unit, but to be adopted, needs to be integrated with other systems used in the Hospital and to train first-time users.
‘Back to the past’: The decline and rebound in traffic accident numbers in Catalonia in the context of COVID-19 lockdown and post-lockdown

ABSTRACT This article analyses the impact of the COVID-19 lockdown and mobility restrictions on interurban traffic accidents in Catalonia, Spain, and how accident numbers and their spatiality changed during the post-lockdown and beginning of the ‘new normal’ period. The authors compared the number of interurban traffic accidents in 2020 with those in the four previous years for the entire period (1 January – 30 September 2020) and for three different subperiods: pre-lockdown, lockdown, and post-lockdown. The results indicate a reduction of almost two-thirds for the entire lockdown period but of more than three-quarters for the hard-lockdown period (first seven weeks). There was an evident rebound in the number of accidents, starting before the end of the lockdown, within a context of flexibilization of mobility restrictions. In September 2020, the number of traffic accidents was the same as in September in the years 2016–2019. The authors conclude that several short-term benefits related to mobility restrictions following the COVID-19 outbreak were lost rapidly in the ‘new normal’ period. They also conclude that the results indicate that some tourist and rural areas have suffered a particular rebound in numbers of accidents during the post-lockdown period.
Characterization of protons accelerated from a 3 TW table-top laser system

We report on benchmark tests of a 3 TW/50 fs, table-top laser system specifically developed for proton acceleration with an intrinsic pump rate up to 100 Hz. In two series of single-shot measurements differing in pulse energy and contrast the successful operation of the diode pumped laser is demonstrated. Protons have been accelerated up to 1.6 MeV in interactions of laser pulses focused on aluminium and mylar foils between 0.8 and 25 μm thickness. Their spectral distributions and maximum energies are consistent with former experiments under similar conditions. These results show the suitability of our system and provide a reference for studies of laser targets at high repetition rate and possible applications.
A Comparative Study of Proposed Ranking Method and Robust Ranking Method in Fuzzy Transportation Problem

Different approaches have been explored in the past to solve fuzzy transportation or fuzzy shipping problems. The cost of shipping, supply, and demand quantities are all ambiguous in a shipping dilemma. Trapezoidal fuzzy numbers are used to represent all of the parameters in this situation. Trapezoidal fuzzy numbers can be converted into crisp numbers using a variety of ranking techniques. In this paper, we've studied the many ranking techniques and provided a comparison of two of them. A numerical example is used to illustrate this.
Matrix integrals and gluings of regular 2n-gons

First time a gaussian matrix model was proposed by E.Wigner to describe the excited states of nuclei. Nowadays matrix models have many applications. In high energy physics the method of 1/N -expansion was presented by G.t’ Hooft [1]. He demonstrated that in the limit of a large number of colors N quantum U(N) YangMills theory is described by the diagrams, which can be drawn on a plane or a sphere. Such diagrams are called planar. Contribution (for example, the partition function) of each chart is included with the factor N in the degree of the Euler characteristic of the surface on which you can draw graphs. Therefore, the contributions of other diagrams are suppressed by 1/N . As is well known, in the main (or planar) approximation of N in the gaussian hermitian matrix model the correlation functions are the Catalan numbers. At the same time, the number for ways of gluings 2n-gon to get the sphere, too, will give the n Catalan number. This coincidence is not accidental. Moreover, J.Harer and D.Zagier [2–4] was found the generating function for the number for orientable gluings of all sorts. It has a surprisingly simple form. The number of gluings 2n-gon, giving a surface of genus g, can be regarded as generalized Catalan numbers eg(n). These numbers were obtained by the recurrence relations. Correlations in this model are even or odd polynomials of degree N . For odd n, we obtain a polynomial of even degree and vice versa. By the way, the main achievement of [2] is even more interesting result, namely the computation of virtual Euler characteristic of the moduli space for the two-dimensional surface of genus g with n marked points. The moduli space is the orbifold for which a cell decomposition has the form R/Gk, where Gk are finite groups. This implies that its is generally not an integer this is true for the manifold. Euler characteristics are expressed in terms of Bernoulli numbers, and are particularly remarkable form of ζ(1− 2g) for a surface of genus g with one marked point. In this report also we will discuss gluings regular 2n-gon for nonorientable surfaces. They are described by gaussian integrals on symmetric matrices. We will present examples of calculations for correlators in this model. They already have the form of polynomials in N with non-zero coefficients for all the terms of the lowest degrees.
Microbunching instability study in a linac-driven free electron laser spreader beam line

Suppression of the microbunching instability is a priority for free electron lasers (FELs) whose goal is production of intense coherent radiation with very narrow spectral bandwidth. The instability can have large gain in multibend switchyard lines that connect the accelerator to multiple undulator lines. This study provides practical guidelines for switchyard optics designs that are largely immune to microbunching growth. A case study of the FERMI FEL switchyard is illustrated, resulting in an improved optics design that provides a unity microbunching gain while preserving the electron beam brightness. The analytical computation of the gain for the improved optics is supported by simulations and by experimental results.
Current flow instability and nonlinear structures in dissipative two-fluid plasmas

The current flow in two-fluid plasma is inherently unstable if plasma components (e.g., electrons and ions) are in different collisionality regimes. A typical example is a partially magnetized E×B plasma discharge supported by the energy released from the dissipation of the current in the direction of the applied electric field (perpendicular to the magnetic field). Ions are not magnetized so they respond to the fluctuations of the electric field ballistically on the inertial time scale. In contrast, the electron current in the direction of the applied electric field is dissipatively supported either by classical collisions or anomalous processes. The instability occurs due to a positive feedback between the electron and ion current coupled by the quasi-neutrality condition. The theory of this instability is further developed taking into account the electron inertia, finite Larmor radius and nonlinear effects. It is shown that this instability results in highly nonlinear quasi-coherent structures resembli.
Tourism and Foreign Direct Investment: An Analysis for Asean Countries

Tourism and foreign direct investment (FDI) plays a role in triggers country economy performance. According to Elma and Adnan (2017), there was a positive relationship between FDI and tourism arrival. Furthermore, this study will investigate both relationship unidirectional and bidirectional yet study will focus on ten ASEAN countries between the year 2004 to 2017 by adopting and beautifying the tourism-led growth hypothesis. Tourism-led growth hypothesis state that economic activities will influence by tourism in the short run and the long run. Besides, panel data will be used with the Random-Effects model and a fixed effects model. The result found that there was a positive relationship between foreign direct investment and tourism, and for the causality also found a positive relationship between tourism and foreign direct investment. As a summary, increasing tourism arrivals will lead to an increase in foreign direct investment and vice versa. The results show that both FDI and tourism arrivals play a role in enhancing economic activity. These relationships as an important tool for policy implication in order to achieve sustainable growth in the tourism sector and for the economy as well and in the same time would give a definite improvement for government policy on foreign direct investment. Besides, the marketers would also benefit by focusing on specific issues mainly in the marketing campaign and learning from their own market trends. Recommendation for future research, we would like to include some variables such as environmental regulation as it is an important deciding factor on how consideration has to be made and mainly conserve the environment from being a polluted and beneficial impact on ASEAN tourism performance.
Inelastic Displacement Ratios for Evaluation of Degrading Peak – Oriented SDOF Systems

Estimation of the inelastic displacement demand (IDD) is an important part of the performance-based design. Coefficient method is one of the methods for the estimation of IDD and in this method, IDD is determined by multiplying elastic displacement demand with inelastic displacement ratio (CR ). Previous researches showed that structures deteriorate and also exhibit dynamic instability under severe earthquakes and these behaviors should be considered in the estimation of CR to estimate a reliable IDD. In this study, CR of the non-degrading bilinear hysteretic model and the degrading peak-oriented hysteretic model with collapse potential were determined and effects of degradation on IDD were investigated. Nonlinear time history analysis of SDOF systems were performed using considered hysteretic models. Furthermore a new equation is proposed for the mean CR of degrading SDOF systems. Also, effect of local site conditions and post-yield stiffness on the mean CR of degrading SDOF systems were investigated.

The impact of retinal size on mental transformations in imagery: Rotation, synthesis, combination

The following paper is an answer to a research question regarding the impact of retinal size (understood as the tangent of the object’s physical size and its distance from the subject) on mental transformations. A total of 182 people took part in three designed experiments, which included three types of operations: 1) synthesis as an operation changing the structure of the object; 2) rotation as an operation preserving the structure of the object; and 3) a combination of the two. The impact of retinal size on the course of rotation was confirmed. Furthermore, it turned out that this impact significantly influenced the effectiveness of all three mental operations. A tendency regarding the impact of physical size on synthesis was demonstrated (participants performed mental transformations in the most optimal way on 15 cm (5.9 in) objects – such that can be held in a hand in the real world). It was noticeable that the optimal distance to the object, preferred by participants, was 30 cm (11.8 in). In the real world, such a distance enables them to transform objects freely within arm’s reach. The obtained results support the analogousness of the mental world to the world in which we live.

Good reduction of dynamical systems with preperiodic level structure and a Shafarevich-type conjecture

Let $K$ be a number field, let $S$ be a finite set of places of $K$, and let $R_S$ be the ring of $S$-integers of $K$. A $K$-morphism $f:\mathbb{P}^N_K\to\mathbb{P}^N_K$ has simple good reduction outside $S$ if it extends to an $R_S$-morphism $\mathbb{P}^N_{R_S}\to\mathbb{P}^N_{R_S}$. A finite Galois invariant subset $X\subset\mathbb{P}^N_K(\bar{K})$ has good reduction outside $S$ if its closure in $\mathbb{P}^N_{R_S}$ is \'etale over $R_S$. The set $X$ is a preperiodic structure for $f$ if it satisfies $f(X)\subseteq X$. We conjecture that there is an $n=n(N,d)$ such that there are only finitely many $\text{PGL}_{N+1}(R_S)$-equivalence classes of pairs $(f,X)$, where $\text{deg}(f)=d$, $\#X\ge n$, $X$ is a preperiodic structure for $f$, and both $f$ and $X$ have good reduction outside $S$. We prove our conjecture for $N=1$ with $n(1,d)=2d+1$. We consider refined questions in which the (weighted) directed graph structure on $f:X\to X$ is specified, we construct associated moduli spaces, and we give an exhaustive analysis for degree $2$ maps on $\mathbb{P}^1$.
Assessing the Awareness Regarding Osteoarthritis and Its Related Risk Factors Among Women in Aseer Central Hospital

Background Osteoarthritis (OA) is the most common form of arthritis worldwide and is characterized by the gradual loss of joint cartilage, leading to stiffness, discomfort, and restricted movement. This research aims to assess the knowledge of obese women in the Aseer region regarding OA and its associated risk factors. OA predominantly affects the knees, hands, and hips, with knee OA being particularly significant due to its high incidence rate and early onset in obese women. In Saudi Arabia, there are varying levels of awareness among the population, but no study has focused on obese females. This study seeks to address this gap and enhance the understanding of OA in this demographic. Methodology A cross-sectional research design was employed using a self-administrated questionnaire collected by a group of trained data collectors who distributed the questionnaires throughout the clinics of Aseer central hospital. The questionnaire was divided into two sections. The first section collected demographic data about the participants, and the second section was a 20-item questionnaire about OA and its related risk factors. The study was conducted in the Aseer region. A total of 278 subjects (female) were included in the study. Statistical analysis was performed using SPSS version 27.0. 1.0 (IBM Corp., Armonk, NY, USA). Results This study analyzed the sociodemographic characteristics of 278 participants. All participants were female, were young to middle-aged adults, and had a collegiate education. On average, participants were overweight, with varying knowledge levels about OA. While some correctly identified symptoms and risk factors. Many participants responded with “I Don’t Know” regarding joint stiffness as a symptom (37.7%). Comparing knowledge among different body mass index groups revealed no significant differences, except for misconceptions about the cause of OA among overweight individuals (39.06%). Conclusions This study’s findings underscore the practical implications for patient education and healthcare strategies. The varying levels of awareness among obese women in the Aseer region regarding OA emphasize the need for increased education and targeted health promotion interventions. Addressing misconceptions and improving knowledge can enhance treatment plans and contribute to better patient outcomes. Understanding these knowledge gaps is crucial for improving patient education, healthcare strategies, and OA management.

Soil invertebrate and microbial activity rehabilitation by compost application after road construction and volcanic disturbance

Topsoil and plants had been removed for the construction of the “De los Siete Lagos” road when the June 2011 Puyehue–Cordón Caulle Complex volcanic eruption deposited 30 cm of tephra. Our objective was to study the active rehabilitation of substrate on roadsides simultaneously affected by road construction and volcanic eruption by compost addition. We studied two biological communities frequently forgotten by rehabilitation measures: invertebrates (density, richness) and microorganisms (enzymatic activities); both in the surface organic matter created by compost addition and the tephra substrate. In December 2012, we installed control, biosolids compost (BC) and municipal waste compost (MC) plots on roadside exclosures. Forest reference sites were also studied. Samplings were performed in spring 2013 and summer 2014. No surface organic matter was found in control plots, and no invertebrates were detected in the tephra layer of control plots in both samplings. BC and MC promoted the formation of a surface organic matter layer that harbored invertebrate and enzymatic activity in both sampling seasons. There were no significant differences in invertebrate density among BC, MC, and forest both in the surface organic matter and the tephra substrate. However, BC and MC invertebrate communities, dominated by springtails, did not resemble the forest community, where oribatids were the most common taxa. Statistically significant differences in total (surface organic matter + tephra substrate) microbial activities indicated a treatment order of forest > BC ≥ MC > control for enzymes related with the mineralization of nitrogen (leucine‐aminopeptidase) and phosphorus (acid phosphomonoesterase).
