Perceptions of Health Sciences Faculty Students about Covid-19 and their Attitudes towards Covid-19 Vaccination

Objective: It is thought that the COVID-19 pandemic can be controlled with an effective and safe vaccination. The thoughts and attitudes of individuals towards the disease and the vaccine are important for the success of vaccination. This study was conducted to determine the perceptions of health sciences faculty students about COVID-19 and their attitudes towards COVID-19 vaccination. Method: A cross-sectional descriptive research design was used. The study consisted of students studying at the Faculty of Health Sciences between June and September 2021. A total of 674 students participated in the study. Findings: The mean age of participants was 20.62±1.88 years, and 85.3% of them were female. Of the participants, 76.1% stated that they had been vaccinated against COVID-19. It was found that positive attitudes towards the COVID-19 vaccine were high among students who were male, were studying nutrition and dietetics, and were 3rd and 4th-year students. Conclusions: In this study determined that most of the students had received the COVID-19 vaccine. Students obtained the lowest score on the belief sub-dimension of the perception of causes of COVID-19 scale and the highest on the environment sub-dimension. It was found that students' scores on the attitudes towards the COVID-19 vaccine scale were moderate.
Study of Validity and Reliability of the GADOT Personality Types Determination Scale Developed Based on Enneagram

Objective: The aim of this research is to conduct an Arabic validity and reliability study of the "GADOT Personality Types Scale" developed based on Enneagram to determine the personality types of those belonging to the Arab culture of immigrants living in Turkey. Method: In this methodological study, data were collected between 1 June and 1 September 2021. The universe of the research consists of immigrant individuals living in Turkey. Using the snowball sampling method, one of the most improbable sampling methods, 500 immigrant individuals who met the inclusion criteria formed the sample of the study. The developed scales are of the 5-point likert type and consist of 64 items. 1.type 9 substance, 2. and 4. type 5 items, 3. , 5. and 7.types 7 items, 6. , 8. and 10.it is in the form of type 8 substance. The height of the scores taken from the scales shows that the personality type measured by the relevant factor is strong in the person. IBM SPSS 22 and AMOS 22 programs were used to evaluate the data. In order to determine the validity of the scales; scope validity, criterion validity and structure validity (exploratory and confirmatory) were performed. Results: As a result of the explanatory factor analysis, it was found that all items showed a significant correlation with each other in the nine sub-dimensions of the GADOT Personality Type Determination Scale (p<0.05). Kaiser-Meyer-Olkin (KMO) and Bartlett's Test results, which indicate the appropriateness of the GADOT Scale for factor analysis and sample adequacy, were found to be significant, since p(sig)=0.000 on all scales. Conclusions and Recommendations: In this research, a personality types identification scale has been developed that evaluates nine personality types based on Enneagram separately. As a result of the analyzes, it was found that the scale models are suitable for their conceptual structure, valid and reliable.
On the existence and strength of the summer subtropical anticyclones : Bernhard Haurwitz memorial lecture

The subtropical anticyclones are usually related to radiative cooling and the descending arm of the Hadley Cell. This explanation works well for the winter anticyclone belt. However, the summer subtropical anticyclones are in most measures stronger, as well as being more longitudinally localized, than their winter counterparts. The nature of the circulations in the summer and winter subtropics, and the Tropics are compared. It is hypothesized that the basic cause of the summer anticyclones is the monsoonal latent heat release over the neighboring continents to the east. As this diabatic heating pushes poleward to near 25° latitude, so deep descent is induced poleward and westward of it. Orographic effects can act to localize this descent. Enhanced radiative cooling and suppressed convection are then viewed as amplifiers of the descent. Under this descent is the equatorward moving air of an anticyclone, which is centered to the west. This wind acts to drive oceanic upwelling, leading to cold sea surface temperatures and reinforcement of the suppression of convection.
Effect of Nasal Aspirator Use on Physiologic Parameters, Crying and Procedure Duration in Nasal Congestion in Infants: A Randomized Controlled Study

Background: Nasal congestion is a significant problem in babies and small children. Aim: To determine the effects of nasal aspirator in nasal congestion in babies on physiologic parameters, crying and procedure duration. Methods: In this study, group 1 underwent nasal aspiration with a nasal aspirator after nasal irrigation with physiologic saline, and group 2 received nasal irrigation alone. Oxygen saturation, heart rate and respiratory rate of the babies in Group 1 and Group 2 were measured, crying and procedure time were evaluated. Results: Group 1 recorded lower SaO 2 values than group 2 immediately before the procedure, but higher values in the other stages (p<0.01). Heart rate values were lower in group 1, but the respiratory rate was higher in group 1 immediately before the procedure (p<0.05). There was no significant difference in respiratory rates between the groups in the other phases of the study (p>0.05). The crying time and procedure duration were longer in group 1 (p<0.01). Conclusion: Nasal aspiration using a nasal aspirator is more effective than nasal irrigation using physiologic saline for the removal of nasal secretions and the achievement of nasal patency.
Experimental Philosophical Logic

The purpose of this chapter is to explore the intersection of experimental philosophy and philosophical logic, an intersection I'll call experimental philosophical logic. In particular, I'll be looldng for and sketching some ways in which experimental results, and empirical results more broadly, can inform and have informed debates within philosophical logic. Here's the plan: first, I'll lay out a way of looking at the situation that makes plain at least one way in which we should expect experimental and logical concerns to overlap. Then, I'll turn to the phenomenon of vague­ ness, where we can see this overlap explored and developed from multiple angles, showing just how intimately related experiment and logic can be. Finally, I'll canvass some other cases where we have similar reasons to expect productive interactions between experimental methods and formal logic, and point to some examples of productive work in those areas.
Analysis of elliptical microstrip patch antenna considering attachment mode

This paper presents an analysis of an elliptical microstrip patch antenna for circular polarization using the method of moments (MOM) in conjunction with the reaction integration method. The attachment mode was used to ensure the continuity and the singularity of the currents in the patch-probe conjunction point. Results showed that an elliptical patch can be used to generate circular polarization with one probe feed and attachment mode should be used to obtain the exact impedance when excited by a probe.
Colorful Results on Euclidean Distance Graphs and Their Chromatic Numbers

In this work, we study Euclidean distance graphs with vertex set Q, the n-dimensional rational space. In particular, we deal with the chromatic numbers (and some related parameters) of such graphs when n = 2 or n = 3. A short history of the topic is given before we approach a few open problems related to the subject. Some of these questions are resolved, either completely or partially. For the problems able to resist our advances, methods are given that hopefully will lead to answers in future work.
Validity of the Point Source Assumption in Rotor Noise Measurements with Shielding

Many theoretical models of shielding by hard surfaces assume the source to be a point monopole source. If one is interested in shielding the noise of a rotor system by interposing a hard surface between the rotor and the observer, can the rotor system really be considered to be a monopole? If rotating noise sources are under consideration what is the effect of configuration and design parameters? Exploring the validity of point source assumption alluded to above for a rotor for far field acoustic measurements with and without shielding form the backbone of the present work. This paper will investigate the validity of acoustic shielding models that are developed under the assumption that the source is a monopole, compared with the shielding of real rotor noise sources. To the author's knowledge, the present research is the first ever work that seeks to answer the question of whether rotor noise from a propeller or a fan can really be approximated by a point source (monopole) as is done in many theoretical calculations when characterizing the effectiveness of acoustic shields. The effect of sound scattered and diffracted by the shield placed around or near the actual source of rotor noise is investigated and compared with data acquired using a point source. Shielding configurations consists of rectangular plates and ducts of various dimensions. closed form solution for velocity potential, V s , as expressed above, used to obtain the shielding of monopole sound waves emanating from a point source by a rectangular plate. The procedure applied was the extended form used by Ahtye and McCulley 2 . This procedure was used to predict the shielding of monopole sound (and can be extended to broadband noise) by simple geometrical shapes (rectangular plate and circular cylinder) in the current work. The basis of the procedure to predict the noise shielding by a rectangular shaped barrier, was superposition of semi-infinite barrier solutions. Each edge of the barrier (barrier can be a rectangular aluminum sheet or an aircraft wing, same procedure is valid) was extended to plus/minus infinity and the solution explained above was applied to all edges as if they were the edge of a semi-infinite plane barrier. The total shielding at a given field point was found from the superposition of semi-infinite barrier solutions of all four edges. The shielding is as the between sound pressure level of the shielded and unshielded cases:
Demagnetization in an inclusive model of ferromagnetic hysteresis

The magnetic tensor response in computational demagnetization simulations of hard magnetic materials is modeled by a new inclusive macroscopic model of ferromagnetic hysteresis, a two-dimensional vector generalization of the classic Stoner-Wohlfarth model. The model includes a mean field interaction and pinning extensions. Both rotating and oscillating demagnetization cycles and isotropic and anisotropic polycrystalline easy axis distributions are treated.
Approach for Teaching Polytropic Processes Based on the Energy Transfer Ratio

The polytropic process equation, Pv n = C, is widely taught in mechanical engineering curricula throughout the world as an important concept in thermodynamics. Unfortunately, it is too often presented as a statement of fact, providing the student with little or no understanding of its fundamental basis. Herein the principal underpinnings of this foundational equation are elucidated by the introduction of a new term, called the energy transfer ratio (K). A teaching approach centered around the energy transfer ratio can give the student new insights into polytropic processes. Reversible polytropic processes in closed and open systems are examined, including open systems where the Mach number is significant. The discussion is then expanded to include irreversible processes. It is hoped that the reader will find this material to be a useful reference in presenting polytropic processes to students.
Stability for Fibre and Morphological Characters in Upland Cotton

Sixteen varieties of upland cotton were evaluated for stability at 6 locations, viz., Jullundur, Ludhiana, Faridkot, Abohar, Sirsa and Hissar. The results indicated significant regression for number of monopods and deviation from regression for number of sympods, plant height and fibre length indicating importance of deviations. The most stable varieties were LH37, H 642 G, 4–1 and D 40 for number of monopods, number of sympods, plant height and halo length respectively. None of the varieties was stable for all the traits. Correlations between means and regressions were significant for plant height and sympod number indicating lines having high mean performance were having below average stability and vice versa.
Weakly-Supervised Temporal Localization via Occurrence Count Learning

We propose a novel model for temporal detection and localization which allows the training of deep neural networks using only counts of event occurrences as training labels. This powerful weakly-supervised framework alleviates the burden of the imprecise and time consuming process of annotating event locations in temporal data. Unlike existing methods, in which localization is explicitly achieved by design, our model learns localization implicitly as a byproduct of learning to count instances. This unique feature is a direct consequence of the model’s theoretical properties. We validate the effectiveness of our approach in a number of experiments (drum hit and piano onset detection in audio, digit detection in images) and demonstrate performance comparable to that of fully-supervised state-of-the-art methods, despite much weaker training requirements.
Self-reported psychotic-like experiences: differences by age and associated psychopathology

This study aims to explore the differences in psychopathological symptoms that may exist in the general adult population with or without psychotic-like experiences (PLEs), depending on the age range. The presence of PLEs, self-reported general psychopathological symptomatology, and different sociodemographic and psychosocial characteristics were assessed in 216 participants without any record of personal psychiatric antecedents. The sample was divided into young adults (18-35 years) and mature adults (36-60 years). The young adults showed a higher expression of PLEs (33.6%). The mature adults with PLEs presented more psychopathological symptoms in the dimensions of hostility-anger, somatization, depression, and anxiety than mature adults without PLEs. Young adults with PLEs showed significantly more symptoms in the same dimensions, and in the obsession-compulsion dimensions, paranoid ideation, and psychoticism, than participants of this age without PLEs. PLEs are more frequent in people between 18-35 years old; however, PLEs can be present in different age ranges and could serve as an alert to high levels of affective and anger-hostility symptoms.
Mechanically Powered Motion Imaging Phantoms: Proof of Concept

Motion imaging phantoms are expensive, bulky and difficult to transport and set-up. The purpose of this paper is to demonstrate a simple approach to the design of multi-modality motion imaging phantoms that use mechanically stored energy to produce motion.We propose two phantom designs that use mainsprings and elastic bands to store energy. A rectangular piece was attached to an axle at the end of the transmission chain of each phantom, and underwent a rotary motion upon release of the mechanical motor. The phantoms were imaged with MRI and US, and the image sequences were embedded in a 1D non linear manifold (Laplacian Eigenmap) and the spectrogram of the embedding was used to derive the angular velocity over time. The derived velocities were consistent and reproducible within a small error. The proposed motion phantom concept showed great potential for the construction of simple and affordable motion phantoms.
Mechanisms of zonal index variability in an aquaplanet GCM

Abstract Data from a 2025-day Geophysical Fluid Dynamics Laboratory aquaplanet GCM integration are used to examine the temporal evolution of the zonal index, defined as the principal component of the first EOF of the zonally and vertically integrated absolute angular momentum. This EOF represents meridional displacements of the subtropical jet. Positive (negative) values of the zonal index correspond to poleward (equatorward) displacements of the subtropical jet and are referred to as the high (low) zonal index. Composites of various quantities are used to examine the temporal evolution of both the zonal-mean zonal winds and the eddy fields associated with either index. The high index is initiated by an enhancement in the equatorward wave activity propagation, which causes the subtropical jet to move in a poleward direction. The low index is led by a weakening in the equatorward propagation, which results in an equatorward displacement of the subtropical jet. More importantly, for the high index, the corr.
Effect of interhemispheric currents on equivalent ionospheric currents in two hemispheres: Simulation results

In this research, we used numerical simulation to study the effect of interhemispheric field‐aligned currents (IHCs), going between two conjugate ionospheres in two hemispheres, on the equivalent ionospheric currents (EICs). We computed the maps of these EICs in two hemispheres during summer‐winter conditions, when the effect of the IHCs is especially significant. The main results may be summarized as follows. (1) In winter hemisphere, the IHCs may significantly exceed and be a substitute for the local R1 currents, and they may strongly affect the magnitude, location, and direction of the EICs in the nightside winter auroral ionosphere. (2) While in summer polar cap the EICs tend to flow sunward, and in winter polar cap the EICs turn toward dawn due to the effect of the IHCs. (3) The well‐known reversal in the direction of the EICs in the vicinity of the midnight meridian, in winter hemisphere, is observed not at the polar caps boundary (as usually expected) but equatorward of this boundary in the region of the IHCs location. (4) The IHCs in winter hemisphere may be, in fact, not only a substitute for the R1 currents but also the major source of the Westward Auroral Electrojet, observed in both hemispheres during substorm activity.
Magnetic instabilities of a rotating gas

We explore two types of instability which may develop when a highly conducting gas rotates rapidly in the presence of a radial gravitational force and an azimuthal magnetic field. Beyond a critical radius (equal to twice the isothermal scale height) a decrease of magnetic flux (per unit mass) outwards leads to the appearance of eastward-propagating waves by the mechanism of ‘magnetic buoyancy’. Within the critical radius an increase of magnetic flux outwards leads to westward-propagating waves by a totally different mechanism. Provided that the effects of Ohmic dissipation are not too large, either instability may set in for quite modest magnetic flux gradients, even when the magnetic energy of the system is very much smaller than the rotational energy.
Reply to arXiv:1810.11506: Size Effect According to the Critical Shear Crack Theory (CSCT) for Reinforced Concrete Beams and Slabs

This document is a reply to arXiv:1810.11506. In that document, Donmez and Bažant raise a number of criticism on the hypotheses Critical Shear Crack Theory (CSCT). The aspects criticized have however been largely discussed in previous works of the CSCT, proving the validity of the theory. This document compiles such previous knowledge as a reply to the authors of the report.
Regimes of enhanced electromagnetic emission in beam-plasma interactions

The ways to improve the efficiency of electromagnetic waves generation in laboratory experiments with high-current relativistic electron beams injected into a magnetized plasma are discussed. It is known that such a beam can lose, in a plasma, a significant part of its energy by exciting a high level of turbulence and heating plasmaelectrons. Beam-excited plasma oscillations may simultaneously participate in nonlinear processes resulting in a fundamental and second harmonic emissions. It is obvious, however, that in the developed plasma turbulence the role of these emissions in the total energy balance is always negligible. In this paper, we investigate whether electromagnetic radiation generated in the beam-plasma system can be sufficiently enhanced by the direct linear conversion of resonant beam-driven modes into electromagnetic ones on preformed regular inhomogeneities of plasma density. Due to the high power of relativistic electron beams, the mechanism discussed may become the basis for the generator of powerful sub-terahertz radiation.
Reflectivity, Rain Rate, and Kinetic Energy Flux Relationships Based on Raindrop Spectra

Abstract The relationships between radar reflectivity factor Z, rainfall rate R, and rainfall kinetic energy flux E were analyzed based on a multiyear raindrop spectra dataset recorded by a Joss–Waldvogel disdrometer in the Goodwin Creek research watershed in northern Mississippi. Particular attention was given to the climatological variability of the relationships and the uncertainty by which one rainfall parameter may be estimated from another. Substantial variability for the coefficients of a power-law relationship Y = AbXb between two rainfall parameters Y and X (where Y and X may stand for any paired combination of Z, R, and E) was found. The variability of the exponent b, however, was small enough to support approaches of climatologically fixed exponents to simplify radar rainfall estimation procedures. The multiplicative factor Ab should typically be adjusted on a storm basis. The uncertainty of the estimation of one rainfall parameter from another, being a function of the difference in weighting o.
