From What They Wrote Came Fire: An Analysis of the Malleus Maleficarum and its Impact

This paper aims to examine the spread of misinformation regarding witches, the cultural environment that allowed texts like the Malleus Maleficarum to flourish, the impact of that text, and the subsequent, bloody consequences that followed for the accused. Using the current literature available I will examine the history of witchcraft and witch hunting, the possible reasons for the witch hunts, and the reality of what it meant to be accused and tried as a witch. I will perform textual content analysis of the Malleus Maleficarum, which I believe to be a foundational text in understanding the cultural and religious implications of subsequent witch hunting practices.Master of Science in Information Scienc

Extreme Ultraviolet Application of Carbon Nanotube Structures

Windows for extreme ultraviolet (EUV) sources are challenging because of the lack of transparent materials in these wavelengths. Thus, differential pumping apertures and slits are standard. Our group has developed a carbon nanotube (CNT) window consisting of a dense array of square holes. The open area allows a large range of wavelengths to be transmitted, and the high density of holes restricts gas flow, allowing a large pressure difference with differential pumping. The versatility of CNTs allows us to select the peak transmission and pressure ratio (low/high). We have observed pressure ratios of 0.000924, 0.000667, 0.000494, and 0.00118 for air at 298 K with (width-heigth in microns) 50-301, 50-654, 50-1045, and 200-675, respectively for (high) pressures up to 1 torr

Compositional stability of FePt nanoparticles on SiO2/Si during annealing

The loss of Fe due to oxidation or diffusion into the substrate can prevent the successful preparation of well-ordered, stoichiometric, FePt nanoparticles. In this work we report the composition changes during annealing observed for small ( \u3c 10 nm) FePt nanoparticles on thermally grown SiO2 layers on Si wafer substrates. Additionally, we describe the use of a controlled reducing gas mixture, Ar+H-2+H2O, to reduce the loss of Fe

Diffusion profiles of high dosage Cr and V ions implanted into silicon

The depth profiles of high dosage Cr-52(+) and V-51(+) ions implanted in (100) crystalline silicon after thermal anneal at temperatures between 300 degreesC and 1000 degreesC are studied by secondary ion mass spectrometry and cross-sectional transmission electron microscopy. At dosages of 1x10(15) ions/cm(2) and above, the surface layer of silicon substrate is amorphorized. During the subsequent thermal annealing, the depth profiles of the implanted ions are strongly coupled with the solid phase epitaxial growth of amorphous silicon. Silicide precipitate formation is important to understand the differences between Cr and V diffusion. After anneal of the 1x10(15) ions/cm(2) implanted samples at 900 degreesC and 1000 degreesC, most of the Cr has left the silicon, but only 10% of the V has escaped. The 1x10(14) ions/cm(2) Cr-implanted sample shows Cr ions exist only near the surface after 1000 degreesC anneal. The V-implanted sample, on the other hand, only shows a narrowing of the V profile after 1000 degreesC anneal

Antiphase ordering and surface phases in lithium aluminate

Antiphase domains are seen in single crystal gamma lithium aluminate (gamma-LiAlO(2)) with 16.7 nm periodicity in the \u3c 110 \u3e direction. Alternate domains have a 1/2 [001] shift. Beta phase lithium aluminate (beta-LiAlO(2)) is seen to form on the surface of the as-received wafers with an epitaxial strain limited relationship with the bulk gamma phase. The orthorhombic beta phase aligns with the a and b axes (0.528 and 0.630 nm) matching with the tetragonal gamma phase\u27s a and c axes (0.5168 and 0.6268 nm). The gamma and beta phases are seen to have different etch rates. The beta phase converts back to the gamma phase above 450 degrees C

Animal-Assisted Interventions: Relationship Between Standards and Qualifications

Ethical practice of animal- assisted interventions (AAI) requires appropriate qualifications and experience for all parties involved. Recently introduced and updated Standards of Practice emphasize the importance of AAI- specific training and qualification for different types of AAI, which should only be delivered within the scope of one’s professional competence. The purpose of this study was (1) to explore how a self- selected group of practitioners delivering AAI describe their work in relation to recent attempts to develop a terminological consensus (IAHAIO, 2014, 2018), and (2) to describe how AAI best practice recommendations (AAII, 2018) are implemented into professional practice among these AAI professionals working with dogs. The study employed an online survey that identified the participants’ qualification level, AAI specific training background, level of AAI experience, and their compliance with recommended guidelines on the documentation and measurement of clients’ progress. Data was collected from an international sample of 239 AAI professionals. A high proportion of respondents who were practitioners in a given field reported holding the necessary basic academic qualification for delivering animal- assisted education (AAE) (82.1%) or animal- assisted therapy (AAT) (91.4%). A substantial proportion delivered specific types of AAI that were beyond their scope of professional practice. A large proportion of respondent practitioners reported that they do not document (27.5%) or measure (28.5%) their clients’ progress as recommended by the professional standards. Experience in AAI was not a significant predictor of compliance with the recommended guidelines on documentation and measurement of clients’ progress; however, professional experience was related to their AAI experience. It is suggested that limitations in the provision of AAI- specific training and awareness of recently updated best practice recommendations influence the quality of AAI across practitioners. Overcoming these issues is essential to further professionalize AAI practice and enhance the quality of intervention programs

Size-dependent melting: Numerical calculations of the phonon spectrum

In order to clarify the relationship between the phonon spectra of nanoparticles and their melting temperature, we studied in detail the size-dependent low energy vibration modes. A minimum model with atoms on a lattice and harmonic potentials for neighboring atoms is used to reveal a general behavior. By calculating the phonon spectra for a series of nanoparticles of two lattice types in different sizes, we found that density of low energy modes increases as the size of nanoparticles decreases, and this density increasing causes decreasing of melting temperature. Size-dependent behavior of the phonon spectra accounts for typical properties of surface-premelting and irregular melting temperature on fine scales. These results show that our minimum model captures main physics of nanoparticles. Therefore, more physical characteristics for nanoparticles of certain types can be given by phonons and microscopic potential models.Comment: 5 pages, 5 figure

Defects in m-face GaN films grown by halide vapor phase epitaxy on LiAlO2

Free-standing wafers (50 mm diameter) of GaN were grown by halide vapor phase epitaxy on lattice-matched gamma-LiAlO2. We report a transmission electron microscopy study of defects and defect densities in these wafers. The growth direction is [10 (1) over bar0]. Stacking faults in the basal plane are seen when viewing the specimen in the [1 (2) over bar 10] direction with an average spacing of less than 100 nm. Convergent beam electron diffraction measurements show no switch in the polarity and thus the faults are proposed to be ABABACAC changes in the stacking. Threading dislocations are found to have a correlated arrangement with a density of 3x10(8) cm(-2) when viewing the [1 (2) over bar 10] direction and widely varying (depending upon location) when viewing in the [0001] direction. These dislocations act as seeds for postgrowth surface features that directly exhibit the correlated nature of these threading dislocations

High Aspect Ratio Carbon Nanotube Membranes Decorated with Pt Nanoparticle Urchins for Micro Underwater Vehicle Propulsion via H2O2 Decomposition

The utility of unmanned micro underwater vehicles (MUVs) is paramount for exploring confined spaces, but their spatial agility is often impaired when maneuvers require burst-propulsion. Herein we develop high-aspect ratio (150:1), multiwalled carbon nanotube microarray membranes (CNT-MMs) for propulsive, MUV thrust generation by the decomposition of hydrogen peroxide (H2O2). The CNT-MMs are grown via chemical vapor deposition with diamond shaped pores (nominal diagonal dimensions of 4.5 × 9.0 μm) and subsequently decorated with urchin-like, platinum (Pt) nanoparticles via a facile, electroless, chemical deposition process. The Pt-CNT-MMs display robust, high catalytic ability with an effective activation energy of 26.96 kJ mol–1 capable of producing a thrust of 0.209 ± 0.049 N from 50% [w/w] H2O2 decomposition within a compact reaction chamber of eight Pt-CNT-MMs in series
