FROM UNDERSTANDING BASIC PARTICLE PHYSICS —to exploring the Universe During the first half of 2013, a number of startling advances in astro-particle physics have been announced. In addition to this--the next ultra large cosmic ray experiment is being developed, regions of the world (including southwest Kansas) tested for their suitability to host such an experiment. In this talk you will get a brief introduction of the ideas of particle physics and how they are being transformed into astro-particle measurements to further understand the Universe and the forces within it.
This presentation deals with current space congestion scenario and the available measures that could be taken to cope with the continually emerging problem.
The James Webb Space Telescope is NASA's next flagship mission. Webb will revolutionize astronomy in the infrared like the Hubble Space Telescope has done for the visible portion of the spectrum over the last 22 years. Webb will reveal the story of the formation of the first starts and galaxies, investigate the processes of planet formation, and trace the origins of life.

Electromagnetic spectrum in Astronomy.pptxmaryammaher2
This is a presentation about a graduation project. It's includes a short intro about electromagnetic spectrum and what is it in Astronomy, the Telescopes used to measure the Radiations coming from outer Space in every region of the EM spectrum.
The James Webb Space Telescope (JWST) is a space telescope designed primarily to conduct infrared astronomy. As the largest optical telescope in space, its greatly improved infrared resolution and sensitivity allow it to view objects too early, distant, or faint for the Hubble Space Telescope. This is expected to enable a broad range of investigations across the fields of astronomy and cosmology, such as observation of the first stars and the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.
Goals: The James Webb Space Telescope is an infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity.
Launch Date: Dec. 25, 2021 | 12:20 UTC
Science Targets: Our Solar System | Beyond Our Solar System
Type :Orbiter
Agency: NASA
Webb will study every phase in the history of our universe, ranging from the first luminous glows after the big bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own solar system. It will build on the Hubble Space Telescope's discoveries
JWST's primary mirror is a 6.5 m (21 ft.)-diameter gold-coated beryllium reflector with a collecting area of 25.4 m2 (273 sq. ft.). If it were built as a single large mirror, this would have been too large for existing launch vehicles. The mirror is therefore composed of 18 hexagonal segments which unfolded after the telescope was launched
JWST operates in a halo orbit, circling around a point in space known as the Sun–Earth L2 Lagrange point, approximately 1,500,000 km beyond Earth's orbit around the Sun.
L2 is short-hand for the second Lagrange Point, a wonderful accident of gravity and orbital mechanics, and the perfect place to park the Webb telescope in space. There are five so-called "Lagrange Points" - areas where gravity from the sun and Earth balance the orbital motion of a satellite

High-resolution observations of solar tornadoes and solar prominencesUniversity of Glasgow
Several observing campaigns have been carried out with the IRIS mission in coordination with other observatories to target solar prominences and prominence-like tornadoes. We focus here on observations between 2014 and 2016. The observational data is being complemented by a grid of non-LTE radiative transfer models producing synthetic Mg II line profiles. An algorithm is used to automatically extract relevant line profile parameters from the optically thick Mg II h and k lines, both on the observed and synthetic profiles. This allows us to study a large set of profiles and provide statistical results. We present our most recent findings from the combined analysis of synthetic spectra and of Mg II spectra acquired by IRIS, in terms of plasma parameters, magnetic fields, and dynamics, with the help of data from other observatories such as SDO, Hinode, the Meudon Solar Tower, and THEMIS. Implications for future high-resolution instruments are discussed.
ALMA will deliver exciting opportunities to advance our understanding of solar prominences and filaments, and constrain models of prominence fine structures.
This presentation introduces Glasgow and Scotland, and describes opportunities to study in the School of Physics and Astronomy at the University of Glasgow, especially for international students.
We present SOPRA (Solar Off-limb Prominence Reconstruction Algorithm), an algorithm
which automatically detects prominences above the limb in EUV images taken in the He II
channel at 304 A and subsequently reconstructs the structures to extract their morphological parameters.
SOPRA determines the characteristics of radial intensity profiles outward from the limb and
uses Support Vector Machines in order to classify them as belonging to prominence or other
structures. Pixels detected as belonging to a prominence are then used as the starting point
to reconstruct the whole object by morphological image processing techniques.
The algorithm is applied to the entire SOHO/EIT data set and a catalogue of detected
prominences is produced. We present the initial statistical analysis of this catalogue, and
discuss its use for solar prominence research and for space weather monitoring.
We also assess the performance of SOPRA when applied to SDO/AIA images.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

extremely challenging and can only be
carried out on a statistical basis.
•Understanding the detailed physical
processes can only be achieved by
getting closer.
