Field: Social Sciences (Social Sciences)

Abstract A Preliminary Evaluation of Elementary School Teachers Willingness to Gain Certification in Science or Mathematics in an Effort Towards Achieving School-wide STEM Certification (RTP, Strand 3)Teacher buy-in is critical to the success of achieving elementary school STEM certification inthe state of Georgia. The goal of the certification program is to provide educational opportunitiesin which students are prepared as 21st century learners. More than 75 percent of a school’s staffmust have a science or math endorsement or middle school science or math certification (bypassing the middle school GACE, Georgia Assessments for the Certification of Educators) or areworking on that endorsement/certification for a school to attain this status. The State of Georgiahas an initiative to increase the number of students prepared for and enrolled in STEM degreeprograms. This initiative developed in response to the critical need for science, technology,engineering, and mathematics (STEM) graduates to ensure the future success of its workforce. Inaddition, there is a necessity to develop the quantity and quality of Georgia’s P-12 science andmathematics teachers. This research focuses on evaluating early education teachers willingnessto receive STEM education training and also assisting them with introducing and implementingSTEM concepts to their students on a daily basis in their classrooms. A survey was developed toassess teachers’ current certifications, comfort level with math and science education, andwillingness to receive additional training, if necessary, in one Georgia elementary school.Preliminary survey results indicate that the majority of teachers were not adequately trained andhad a low level of interest and willingness to receive additional training. This research willpresent the final results of a school-wide survey as well as present an action plan for furtherteacher engagement and buy-in towards the achievement of STEM certification for the school.

Each power supply module comprises one energy storage capacitor, a thyristor stack, a corresponding number of crowbar diodes and a well-designed coaxial power line serving as a pulse forming network and current limiting reactor. The paper presented here describes the basic design of the 50 kJ energy pack, a further developed set-up with a reduced overall height obtained by using a novel multichip thyristor and the broad field of applications for such high-power supply units
The Phytochemical and Pharmacological Properties of Portulaca

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The Portulacaceae family includes Portulaca oleracea L., also known as purslane in English and Ma-Chi-Xian in Chinese. An annual grassy plant is widely cultivated across the world, particularly in tropical and subtropical regions. Around the Mediterranean and in tropical Asian nations, it is widely used as a potherb and added to soups and salads. It has also been used as a folk remedy in numerous nations. Many different substances, including flavonoids, alkaloids, polysaccharides, fatty acids, terpenoids, sterols, proteins, vitamins, and minerals, have been extracted from Portulaca oleracea. A comprehensive range of pharmacological qualities, counting neuroprotective, antibacterial, antidiabetic, antioxidant, anti-inflammatory, antiulcerogenic, and anticancer actions, are present in Portulaca oleracea. However, little is known about molecular mechanisms of action. The phytochemistry and pharmacological properties of this plant are summarised here.
Navigating Identity and Belonging: A Critical Analysis of Ruskin Bond’s The Room on the Roof

Field: Arts and Humanities (Social Sciences)

This study explores the detailed themes of identity, belonging, and cultural dislocation as presented in Ruskin Bond's seminal work, The Room on the Roof. The novel, set in postcolonial India, follows the journey of Rusty, a young Anglo-Indian boy, as he navigates the complexities of adolescence and self-discovery against a backdrop of cultural contrasts. Employing a qualitative analytical approach, this research delves into the protagonist's emotional and psychological landscape, highlighting how Bond's narrative style, characterized by vivid imagery and poignant characterization, deepens the exploration of these themes. Through a careful examination of Rusty’s relationships with his Indian friends and his connection to his British heritage, the study reveals the duality of belonging and alienation experienced by individuals in a multicultural society. The findings indicate that Bond’s portrayal of Rusty's struggle is not merely a personal journey but a reflection of broader societal issues, including the impact of colonial history on personal identity. Ultimately, this paper underscores the significance of understanding cultural hybridity and the fluid nature of identity in a rapidly changing world, advocating for an appreciation of diversity as a vital aspect of self-discovery.
AI and embryo transfer for genetic improvement in sheep: the current scene

Field: Agricultural and Biological Sciences (Life Sciences)

SCIENTIFICALLY based programmes for the genetic improvement of sheep which combine the objective assessment of body composition with the reproductive technologies of artificial insemination (Al) and multiple ovulation and embryo transfer (MOET) are now beginning to make a significant impact on the UK sheep industry. The economic benefits of these techniques, however, require to be weighed against the welfare costs of the procedures involved, and efforts need to be made to improve the available methodologies. This article reviews the current applications of these reproductive technologies within sheep breeding and the ongoing research aimed at improving their efficiency and acceptability.
Comparative Study of Wavelet-based Recent Spectral Decomposition Algorithms for Seismic Signals

Field: Earth and Planetary Sciences (Physical Sciences)

Summary Spectral decomposition has become an attribute of immense use for both processing and interpretation of seismic and other geophysical data. Crucial and continuous developments as well as modifications have been proposed to improve and enhance the abilities of such schemes which has led to the development of numerous spectral decomposition schemes which necessitates a comparison. This study compares two relatively recently proposed improved and optimized wavelet based spectral decomposition schemes, namely TFCWT and SFMPD. It gives a brief overview of each and describes the underlying idea and the algorithm behind each scheme. We further apply the spectral decomposition schemes to synthetic and real seismic waveforms and compare the results from each in terms of the resolution and localization abilities. The study also attempts to quantify the result in terms of deviation of observed peak frequency from the overprinting wavelet.
Modelling the dielectric properties of the geyser deposited snow layer on Enceladus

Field: Earth and Planetary Sciences (Physical Sciences)

&lt;p&gt;Saturn&amp;#8217;s icy moon Enceladus is with its roughly 500 km diameter a differentiated geological active body that harbours a liquid ocean between its rocky core and icy mantle. This ocean is among the most promising places to host extraterrestrial life in our solar system.&lt;/p&gt;&lt;p&gt;At Enceladus&amp;#8217; south pole terrain, active geysers form a passage from the ocean to the surface; erupting ice, dust and gas particles. Most of those particles escape the moon&amp;#8217;s gravity, but some portion falls back to the surface. Considering the current output, about 10 m of snow gets sedimented at a distance of about 100 m away from the geyseres within 10&lt;sup&gt;5&lt;/sup&gt;-10&lt;sup&gt;6&lt;/sup&gt; years. Hence, depending on the timescale the geysers are active at the same location, the snow layer would have a thickness of some km already, assuming no densification.&lt;/p&gt;&lt;p&gt;A first model of the density profile of the snow layer as a function of the ice/vacuum ratio will be provided at the conference. To investigate the density at the surface, mainly the distribution of the ice grain shapes and the grain sizes have to be considered and put into a state equation. For modelling the density change in respect to the depth, also the pressure from the overlying weight has to be accounted for. As temperatures at Enceladus&amp;#8217; surface are too low, neither sintering nor processes such as melting and re-freezing can thereby contribute to densification. These processes however are acting in terrestrial glaciers. We propose therefore, because the temperatures on Enceladus are far below the melting point of ice, to consider the ice grains on Enceladus rather as sand than as snow in respect to these materials on Earth, when modelling the density within the snow layer.&lt;/p&gt;&lt;p&gt;After obtaining the ratio between ice and vacuum, it is possible to define the dielectric properties of the snow layer. The dielectric profile in turn is the primary diagnostic property for radar based geophysical investigation. It determines the velocity of radio waves in a medium as well as their reflection and refraction at interfaces. &lt;br&gt;Because of the above mentioned possibility that primitive extraterrestrial life might exist in Enceladus&amp;#8217;&amp;#160; hidden ocean, there will likely be future space missions with the aim to reach a water reservoir and probe it. A well-defined density profile could then help to radar navigate a melting probe through the ice.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;
THE MAYER VIETORIS SEQUENCE CALCULATING DE RHAM COHOMOLOGY

Field: Mathematics (Physical Sciences)

De Rham cohomology it is very obvious that it relies heavily on both topology as well as analysis. We can say it creates a natural bridge between the two. To understand and be able to explain what exactly de Rham cohomology is to the world of mathematics we need to know de Rham groups. This is the reasons to calculate the de Rham cohomology of a manifold. This is usually quite difficult to do directly. We work with manifold. Manifold is a generalization of curves and surfaces to arbitrary dimension. A topological space M is called a manifold of dimension k if : Â· M is a topological Hausdorff space . Â· M has a countable topological base. Â· For all mâˆˆM there is an open neighborhood UâŠ‚M such that U is homeomorphic to an open subset V of â„k. There are many different kinds of manifolds like topological manifolds, â„‚k - manifolds, analytic manifolds, and complex manifolds, we concerned in smooth manifolds. A smooth manifold can described as a topological space that is locally like the Euclidian space of a dimension known. An important definion is homeomorphism. Let X, Y be topological spaces, and let f: XâŸ¶Y e a bijection. If both f and the inverse function fâˆ’1: XâŸ¶Y are continuous, then f is called a homeomorphism We introduce one of the useful tools for this calculating, the Mayer â€“ Vietoris sequence. Another tool is the homotopy axiom. In this material I try to explain the Mayer â€“ Vietoris sequence and give same examples. A short exact sequence of cochain complexes gives rise to a long exact sequence in cohomology, called the Mayer - Vietories sequence. Cohomology of the circle (S^1), cohomology of the spheres (S^2). Homeomorphism between vector spaces and an open cover of a manifold. we define de Rham cohomology and compute a few examples.

Comparative law and Chinese legal tradition: through the lens of judicial precedent

Field: Arts and Humanities (Social Sciences)

This chapter discusses the importance of Chinese law to future comparative law studies. The importance of Chinese law may be attributable to a number of different reasons. The task is, however, not to produce a full list of reasons, but to set the stage for a close look at one of them, namely the continuity of some elements of a legal tradition that has run its course for thousands of years. To illustrate how heritage in the long past might continue to shape the present, this chapter addresses the precedent system in the Qing Dynasty, outlining some of its most salient features and exploring its links to the present-day equivalent. Chapter seeks to bridge the temporal gap between the Qing system and the precedent system in China today. Knowing the past, it hopes, will not only improve understanding of the present, but also facilitate, to a more limited extent, the prediction of the future.
Maintenance outsourcing coordination with risk-averse contractors

Field: Decision Sciences (Social Sciences)

Under a maintenance outsourcing contract, an external contractor receives a fixed payment from a manufacturer for periodically performing preventive maintenance and for performing minimal repairs whenever process failures occur. If the contractor's maintenance policy results in a process uptime above a target level specified in the contract, the contractor receives a bonus payment based on the difference between the uptime and the target levels. We study the optimal designs of maintenance outsourcing contracts for achieving channel coordination when the contractor is risk averse towards uncertain repair costs caused by process failures. We find cases in which channel coordination cannot be achieved because of the contractor's risk preference. Furthermore, the contractor's risk preference may make channel coordination more difficult or easier, depending on the parameters considered in the model.
Quality-control testing for asbestos analysis with synthetic bulk samples

Field: Environmental Science (Physical Sciences)

Asbestos-containing bulk samples which are routinely synthesized in the laboratory from known masses of readily available materials are part of an internal quality-control testing program. Quantitative analysis of asbestos in these samples by a laboratory's standard procedure yields precision and accuracy of that procedure. Permanent microscope-slide preparations of these samples are used specifically to assess polarized-light microscopic (PLM) analyses. Archives of these samples become references for field samples and allow determination of long-term precision and accuracy. The reliability of a two-step PLM method is determined by the above method.
Regulation of CD8+ T Lymphocyte Fate Specification by Proteasome Activity and Cellular Metabolism

Field: Immunology and Microbiology (Life Sciences)

In an immune response, CD8+ T lymphocytes can differentiate into effector cells that acutely clear the infection as well as memory cells that provide lasting immunity against the same pathogen. Previous studies have shown that differentiation of CD8+ T cells in to effector and memory subsets occurs in a heterogeneous manner. Single-cell RNA-seq has revealed that transcriptional heterogeneity is present as early as the first cell division. Using single-cell transcriptional profiling to create supervised classifiers revealed that the outcome of intermediate-stage cells could be predicted. In âpre-effectorâ and âpre-memoryâ cells resulting from the first CD8+ T cell division in vivo, we observed distinctly low and high levels of proteasome activity, respectively. Pharmacological inhibition of proteasome activity early during differentiation resulted in acquisition of terminal effector cell characteristics, while enhancement of proteasome activity conferred attributes of memory lymphocytes. Transcriptomic and proteomic analyses revealed that modulation of proteasome activity in CD8+ T cells affected cellular metabolism. These metabolic changes were mediated, in part, through differential expression of Myc, a transcription factor that controls glycolysis and metabolic reprogramming. Overall, these findings demonstrate that proteasome activity is an important regulator of CD8+ T cell fate early during the differentiation process.
Annoglabrin A-C, three new ent-kaurane diterpenoids from the Annona glabra fruit pulp

Field: Chemistry (Physical Sciences)

Three new ent-kaurane diterpenoids, namely annoglabrin A-C (1-3), were isolated from the Annona glabra fruit pulp. Their structures were clarified by widespread spectroscopic analyses (1D and 2D NMR, HRESIMS). The relative configuration of these new compounds was established through the NOESY spectrum. Compounds 1-3 were evaluated for their inhibitory activity against α-glucosidase and were found with weak (1 and 3) or no effects (2), compared to those of positive control (acarbose, IC50 82.0 µM).
