Observations of high mass star formation using BLAST and Herschel

In this thesis, I present BLAST observations of the Carina Nebula and Herschel observations of NGC7538. I use the source extracting routine CSAR to identify 172 source in Carina and 94 sources in NGC7538. I fit SEDs to all the sources and calculate their mass, luminosity, temperature and radius. For the Carina Nebula I find a mass range of 20 – 10 4M¯, a luminosity range of 10 2 – 10 5 L¯, a temperature range of 16 – 28 K, and source radii range of 0.3 – 3.2 pc. For NGC7538 I find a mass range of 5 – 10 3M¯, a luminosity range of 5 – 10 3 L¯, a temperature range of 10 – 40K and a source radii range of 0.1 – 2 pc. I cross - check the source extraction method using the routine, GETSOURCES. This algorithm found a total of 621 sources in NGC7538. The GETSOURCES catalogue is filtered to removed sources which are present in two or less wavelengths. This filtered catalogue then has a good correlation with the CSAR catalogue. Using both catalogues a robust source list of 75 sources is created from sources found by both routines. I plot the mass against radius for both the Carin Nebula and NGC7538. For Carina the data are best fitted by M / R1.8 which is comparable to the Larson relation of M / R2. In NGC7538 I find no relation. I find no temperature dependence in the Carina Nebula with any other source property but find a weak relation between temperature and luminosity in NGC7538. Both regions show a relation of L / M. I find a relation between radius and Luminosity per unit volume where smaller sources have a higher luminosity per unit volume and the larger sources have a lower value. I find sources with a luminosity per unit volume less then 1L¯pc−3 tend to lie in the less dense regions of the nebulae and sources with a luminosity per unit volume greater then 3.5L¯pc−3 lie in the denser regions where the more evolved sources tend to be. This could show that the luminosity per unit volume can trace the evolutionary status of sources in a region.
Introduction to Integral Discriminants

= ∫ e1n dx1 . dxn. Actually, S-dependence remains the same if e −S in the integrand is substituted by arbitrary function f(S), i.e. integral discriminant is a characteristic of the form S itself, and not of the averaging procedure. The aim of the present paper is to calculate Jn|r in a number of non-Gaussian cases. Using Ward identities – linear differential equations, satisfied by integral discriminants – we calculate J2|3, J2|4, J2|5 and J3|3. In all these examples, integral discriminant appears to be a generalized hypergeometric function. It depends on several SL(n) invariants of S, with essential singularities controlled by the ordinary algebraic discriminant of S.
Design of a cross-connected charge pump for energy harvesting systems

For energy harvesting systems, a novel charge pump with cross-connected structure is proposed in this paper. Owing to the cross-connected structure, the proposed charge pump can offer the output voltage to the output load at every phase. Furthermore, the proposed charge pump can reduce the number of circuit stages from the conventional charge pump. For above-mentioned reasons, the proposed charge pump can realize not only smaller internal resistance but also smaller output capacitance than the conventional charge pump. The theoretical analysis and simulation program with integrated circuit emphasis (SPICE) simulation demonstrate that the proposed charge pump outperforms the conventional charge pump in the point of power efficiency and circuit speed.
Quenched large deviations for multidimensional random walk in random environment: a variational formula

We take the point of view of the particle in a multidimensional nearest neighbor random walk in random environment (RWRE). We prove a quenched large deviation principle and derive a variational formula for the quenched rate function. Most of the previous results in this area rely on the subadditive ergodic theorem. We employ a different technique which is based on a minimax theorem. Large deviation principles for RWRE have been proven for i.i. d. nestling environments subject to a moment condition and for ergodic uniformly elliptic environments. We assume only that the environment is ergodic and the transition probabilities satisfy a moment condition.

A New Way of Teaching Ancient History: The Case of the Bachelor’s of Education at the University of Seville

Even though each project had its own main goals, the primary purpose of all of them was to promote learning and improve the performance and intellectual possibilities of undergraduates in education who took history, and Ancient History in particular, as part of their curriculum. The cornerstone was boosting a largely autonomous, although directed, type of learning to maximise the efficiency of the efforts of both the students

The aim of the study is to investigate the effects of explosive strength training applied to futsal athletes for 8 weeks on determined physical and physiological parameters. Experimental group took explosive strength training 3 days in a week. The control group did not perform any sports activities for 8 weeks. The experimental group of the study consisted of n = 18 male futsalists with age 21.2±1.9 years, height 1.79±,038 cm and weight 71.9±4.05 kg. The control group consisted of n=18 male futsalists with age 22.3±2.2 years, 1.77±,046 cm and a body weight 73.48±3.98 kg. The participants are university students and the studies are planned in a way that will not hinder their education. In the statistical analysis research, the results of futsal players were evaluated in the SPSS-19 program. It was seen that the values obtained from the participants showed normal distribution. The results obtained from participants were evaluated with the paired-T test. After the rapid force studies, there was a statistically significant difference in the handgrip values of the experimental group athletes, while there was no significant difference in the control group. There was no statistically significant difference in experiment and control group of body weight, total muscle rate, body fat percentage, flexibility, 10m speed, vertical jump, shot velocity, resting heart rate (RHR), anaerobic power values (p<0.05). Tests were applied to all participants before and after the studies.
A Framework for Fostering Emerging Online Learner Persistence: The Role of Asynchronous and Synchronous Discussions

Undergraduate students living on-campus and taking online and face-to-face courses concurrently, are the predominant consumer of online classes (Seaman et al., 2018). However, they have lower rates of persistence for online courses as compared to face-to-face courses (Hart, 2012; Xu & Jaggars, 2011). Part of the reason could be due to the mismatch between the types of interactions they prefer and what is being provided in online courses. The purpose of this literature review is to investigate the use of asynchronous and synchronous discussions as a way to address the needs of emerging online learners. Using elements of previously developed frameworks, I propose the Framework for Emerging Online Learner Persistence (FEOLP). This framework addresses the values and needs of emerging online learners through course design that has the potential to enhance social presence using student values to determine the blend of asynchronous and synchronous interactions. Given the limited research to draw from on how to design online courses, this framework and the recommendations from this article provide a starting point for the responsive design of online courses for the emerging online learner with potential application to other groups of distinct online learners.

In this study, the computational thinking skills (CTS) of vocational high school students were examined and the CTS skills were compared in terms of different variables. In this context, the effect of gender, school, grade level, programming experience and computer ownership on CTS skills was investigated. The sample of the study consists of 591 students in the age group of 13-18 years. 51.1% of the students have a high CTS skill level. In addition, 44.3% of students have moderate CTS skills, while 4.6% of students have low CTS skills. The results of this research are important in terms of revealing the average CTS levels of vocational high school students, showing that CTS skills can differ depending on the class level, and that collaboration and critical thinking skills can differ according to the type of school.
NOTES AND CORRESPONDENCE A Note on the Stability of the Tropical Easterlies

Nitta and Yanai (1969) showed that only on some occasions did the observed easterly winds in the neighborhood of the Marshall Islands satisfy the necessary condition for barotropic instability, namely that the potential vorticity gradient (*-Uyy) changes sign. (1) (The latitudinal profile of the winds is described by U(y) where y measures distance in a northward direction. ) They concluded that barotropic instability of the easterlies could be a weak mechanism for the generation of the disturbances with a period of 4 to 5 days observed along the Intertropical Convergence Zone. It is the purpose of this note to point out that the necessary condition for instability (1) applies to non-divergent flow, and may be too stringent if the effects of divergence are taken into account. Lipps' (1963) study of the effects of divergence on barotropic instability is extended to cases of arbitrarily large growth rates. A linear but ageostrophic model is used so that equatorial winds can be studied. (For a detailed description of the model, and of the general results, see Philander (1976). This note concerns only the meteorological implications of the results. ) The importance of divergence is found to depend on the latitudinal profile of the mean winds. We consider two examples: winds with a shearlayer-like structure, such as the easterlies over the Marshall Islands (Nitta and Yanai (1969), and winds with a jet-like structure such as the easterlies over North Africa (Burpee 1972) and the easterlies over the Line Islands (Nitta and Yanai 1969). Winds that resemble a shear layer are shown to be stabilized by divergence, except when the mean flow is marginally unstable, in which case divergence is weakly destabilizing; (see Fig. 1). Jets are shown to be stabilized by divergence
Title Eye-tracking the emergence of attentional anchors in a mathematics learning tablet activity

Little is known about micro-processes by which sensorimotor interaction gives rise to conceptual development. Per embodiment theory, these micro-processes are mediated by dynamical attentional structures. Accordingly this study investigated eye-gaze behaviors during engagement in solving tablet-based bimanual manipulation tasks designed to foster proportional reasoning. Seventy-six elementaryand vocational-school students (9-15 yo) participated in individual task-based clinical interviews. Data gathered included action-logging, eye-tracking, and videography. Analyses revealed the emergence of stable eye-path gaze patterns contemporaneous with first enactments of effective manipulation and prior to verbal articulations of manipulation strategies. Characteristic gaze patterns included consistent or recurring attention to screen locations that bore non-salient stimuli or no stimuli at all yet bore invariant geometric relations to dynamical salient features. Arguably, this research validates empirically hypothetical constructs from constructivism, particularly reflective abstraction.

On the prescribing $\sigma_2$ curvature equation on $\mathbb S^4$

Prescribing $\sigma_k$ curvature equations are fully nonlinear generalizations of the prescribing Gaussian or scalar curvature equations. Given a positive function $K$ to be prescribed on the 4-dimensional round sphere. We obtain asymptotic profile analysis for potentially blowing up solutions to the $\sigma_2$ curvature equation with the given $K$; and rule out the possibility of blowing up solutions when $K$ satisfies a non-degeneracy condition. We also prove uniform a priori estimates for solutions to a family of $\sigma_2$ curvature equations deforming $K$ to a positive constant under the same non-degeneracy condition on $K$, and prove the existence of a solution using degree argument to this deformation involving fully nonlinear elliptic operators under an additional, natural degree condition on a finite dimensional map associated with $K$.
Some field theoretical properties and an application concerning transcendental numbers

For a proper subfield $K$ of $\QQ$ we show the existence of an algebraic number $\alpha$ such that no power $\alpha^n$, $n\geq 1$, lies in $K$. As an application it is shown that these numbers, multiplied by convenient Gaussian numbers, can be written in the form $P(T)^{Q(T)}$ for some transcendental numbers $T$ where $P$ and $Q$ are arbitrarily prescribed non-constant rational functions over $\QQ$.
(1+1)-dimensional separation of variables

In this paper we explore general conditions which guarantee that the geodesic flow on a two-dimensional manifold with indefinite signature is locally separable. This is equivalent to showing that a two-dimensional natural Hamiltonian system on the hyperbolic plane possesses a second integral of motion which is a quadratic polynomial in the momenta associated with a secind rank Killing tensor. We examine the possibility that the integral is preserved by the Hamiltonian flow on a given energy hypersurface only (weak integrability) and derive the additional requirement necessary to have conservation at arbitrary values of the Hamiltonian (strong integrability). Using null coordinates, we show that the leading-order coefficients of the invariant are arbitrary functions of one variable in the case of weak integrability. These functions are quadratic polynomials in the coordinates in the case of strong integrability. We show that for (1+1)-dimensional systems, there are three possible types of conformal Killing.
Stability and instability results in a model of Fermi acceleration

We consider the static wall approximation to the dynamics of a particle bouncing on a periodically oscillating infinitely heavy plate while subject to a potential force. We assume the case of a potential given by a power of the particle's height and sinusoidal motions of the plate. We find that for powers smaller than 1 the set of escaping orbits has full Hausdorff dimension for all motions and obtain existence of elliptic island of period 2 for arbitrarily high energies for a full-measure set of motions. Moreover we obtain conditions on the potential to ensure that the total (Lebesgue) measure of elliptic islands of period 2 is either finite or infinite.
Braid Group Representations arising from the Yang Baxter Equation

This paper aims to determine the images of the braid group under representations afforded by the Yang Baxter equation when the solution is a nontrivial $4 \times 4$ matrix. Making the assumption that all the eigenvalues of the Yang Baxter solution are roots of unity, leads to the conclusion that all the images are finite. Using results of Turaev, we have also identified cases in which one would get a link invariant. Finally, by observing the group algebra generated by the image of the braid group sometimes factor through known algebras, in certain instances we can identify the invariant as particular specializations of a known invariant.
Normal subgroups of diffeomorphism and homeomorphism groups of ℝn and other open manifolds

Abstract We determine all the normal subgroups of the group of Cr diffeomorphisms of ℝn, 1≤r≤∞, except when r=n+1 or n=4, and also of the group of homeomorphisms of ℝn ( r=0). We also study the group A0 of diffeomorphisms of an open manifold M that are isotopic to the identity. If M is the interior of a compact manifold with non-empty boundary, then the quotient of A0 by the normal subgroup of diffeomorphisms that coincide with the identity near to a given end e of M is simple.
Transformational leadership and patient safety in hospital: The roles of safety culture, decision-making capacity, and locus of control

This study examines to make up this significant gap in the existing literature. Using a cross-sectional sample consisting of 240 nurses in the hospitals of Uzbekistan and a structural model, with a random sampling technique by employing explanatory, and causal design was used to test the developed framework. Quantitative data was collected using questionnaires, the survey instruments were distributed by hand among the private and public sector, we find that nurses’ perceived safety culture (SC) and decision-making capacity (DMC) act as important mechanisms linking TL to PS. Meanwhile, nurses’ perceived locus of control (LC) moderates the effect of TL on SC and DMC in such way that this effect is more salient for nurses with internal LC than for nurses with external LC. This paper examines the contribution, that individuals with high internal LC are more affected by TL, generate and can better develop SC and DMC. The study findings demonstrated the significant role of transformational leadership played in order to improve working conditions and the environment, which helps nurses to create good conditions, relationships with patients and increase patient safety. The theoretical and practical implications of this study are discussed. © 2021 by the authors. Licensee SSBFNET, Istanbul, Turkey.

Chiral condensate at nonzero chemical potential in the microscopic limit of QCD

The chiral condensate in QCD at zero temperature does not depend on the quark chemical potential (up to one-third the nucleon mass), whereas the spectral density of the Dirac operator shows a strong dependence on the chemical potential. The cancellations which make this possible also occur on the microscopic scale, where they can be investigated by means of a random matrix model. We show that they can be understood in terms of orthogonality properties of orthogonal polynomials. In the strong non-Hermiticity limit they are related to integrability properties of the spectral density. As a by-product we find exact analytical expressions for the partially quenched chiral condensate in the microscopic domain at nonzero chemical potential.
TEACHERS’ SUBJECTIVE THEORIES ABOUT THE EMPLOYMENT INTEGRATION THEIR BLIND STUDENTS

Even though research has been conducted on the employment integration at blind people, studies have failed to consider what teachers think and know about their blind students’ difficulties entering the workforce after completing their education. The aim of this qualitative study was to understand the subjective theories of six teachers from a school in La Serena, Chile. In-depth interviews were used to collect data, which were subsequently studied using grounded theory coding procedures and subjective theory content analysis. The main finding of this study was that participants regarded the inadequate education of blind people as the key reason for their employment difficulties. This study can provide valuable information for policymakers focusing on visual impairment.
The role of personality traits in following quarantine orders during the COVID-19 pandemic

Patients’ personalities seem to affect their response to the COVID-19 pandemic. This study examined the association of personality traits and characteristics of Iranian COVID-19 outpatients with their compliance to nonmandatory quarantine orders. This cross-sectional study was conducted in 2020-2021 on 97 COVID-19 outpatients. The temperament and character inventory-revised short version (TCI-RS) and a self-report checklist assessing compliance with quarantine orders were used to collect data. SPSS was used to analyze the data and P < 0.05 was considered statistically significant. Of 142 patients who were contacted, 97 participated in the study (68% response rate). The mean age of patients was 39.21 ± 10.27 years and 54 (55.7%) of them were men. Compliance with quarantine orders was correlated with cooperativeness (r = 0.33; P = 0.001), persistence (r = 0.23, P = 0.020), self-transcendence (r = 0.27, P = 0.006) and harm avoidance (r = -0.26, P = 0.008). Linear regression analysis demonstrated persistence (P = 0.034), cooperativeness (P = 0.008) and being married (P = 0.002) as predictors for following the quarantine orders. Lower levels of cooperativeness, persistence, self-transcendence, and higher levels of harm avoidance are associated with noncompliance with quarantine orders. These traits should be considered while persuasive communication to the public is formulated to recognize the target population and increase compliance with nonmandatory quarantine orders.
