Gold prices have risen in recent years due to several factors:
1) A weak US dollar has made gold a more attractive investment as the dollar declines.
2) Low interest rates and rising inflation have reduced the appeal of other assets like bonds and savings accounts.
3) Economic crises and political instability increase demand for gold as a safe haven investment.
The document discusses the impact of gold on the Indian economy. It provides background on gold, including its properties and top gold consuming and producing countries. India is the largest consumer of gold globally. The document then examines how gold impacts key economic indicators in India like the Sensex stock market index, interest rates, exchange rates, and inflation. When economic conditions are unstable, investors tend to switch to gold as an alternative investment. Rising gold prices are often associated with falling interest rates and a depreciating rupee. Gold also serves as a hedge against inflation in India as millions regard it as a form of money.

Metallic minerals occur naturally in rare mineral deposits containing valuable metals like nickel, copper, zinc, lead, and gold. These metals must be extracted from minerals through breaking them apart and chemical processing. Ontario is a major producer of metals, generating $450 billion from metal production, and companies spent $502 million exploring for new mineral deposits in 2007. Copper is a soft, reddish-orange metal that is highly conductive of heat and electricity and used as a building material and in alloys.
Dmitri Mendeleev created the periodic table by organizing the known elements based on their atomic structure. He arranged the elements in increasing atomic number from left to right and top to bottom in a manner that reflected their recurring chemical and physical properties. The periodic table displays the elements grouped into metals, nonmetals, and metalloids and is organized into rows called periods and columns called groups based on their valence electrons. This organization allows scientists to predict properties and discover new elements.
South Australia is the state located in the southern part of Australia. Its capital is Adelaide. It is the 4th largest of Australia's 8 states and territories. In South Australia, many people live underground in Coober Pedy to stay cool in the hot climate, as the area is located near the center of Australia. Another unique feature is Blue Lake in Mount Gambier, which has bright blue water that changes color and is located in a volcanic crater. South Australia also has its own flag depicting its history and symbols like the Piping Shrike bird and Hairy Nosed Wombat animal.
The Philippines has abundant mineral resources due to its location within the Pacific Ring of Fire. It is ranked 5th globally in terms of mineralization. Around 9 million hectares of land are believed to contain important metallic mineral deposits, with estimated reserves of 14.5 billion metric tons. Major metallic minerals found in the Philippines include gold, copper, nickel, and silver. The top gold and copper producing regions are in Benguet and Surigao-Davao. Nickel is largely produced in Palawan and Surigao. In 2014, metallic mineral production value rose substantially to 137.53 billion pesos, with nickel, gold, and copper making up the majority.

1. India is one of the world's largest silver markets, consuming over 4,996 tons annually which represents 16% of global silver demand.
2. Indian silver demand comes from personal consumption such as jewelry, silverware, and physical investment, which together account for around 75% of demand. The remaining demand is industrial.
3. India imports silver to meet demand as domestic silver production of 436 tons per year is far below total Indian silver needs. India also recycles around 100 tons of silver annually from scrap.
The document discusses the relationship between a metal's reactivity and when it was discovered. It analyzes metals discovered at different points in history and finds that generally, less reactive metals like gold were discovered earlier since they occur freely in nature, while more reactive metals discovered later once technology advanced to extract them from ores. There is not always a direct correlation, as in the case of copper being discovered before silver, but the pattern typically holds except over very short periods. The conclusion is that less reactive metals were discovered earlier due to being more easily accessible.
The document discusses the history and value of silver as both an industrial and investment metal. It notes that silver has many industrial uses but stocks are dwindling rapidly due to high demand. It promotes silver as a sound investment that provides portfolio diversification and protection against economic instability. It encourages contacting Lear Capital to discuss options for purchasing silver coins, bars, or setting up a silver-backed IRA for retirement protection and investment.
The current price of silver is providing a rare window of opportunity for investors to establish a
sound position before this “poor man’s metal” makes its move higher.
Gold has been used by humans for over 5,000 years. It gets its name from the old English word 'Geolo' meaning yellow. Minor amounts of gold are found naturally in many substances like seawater and rocks. To extract gold, ore containing traces of gold must be mined and processed. Pure gold is very malleable and ductile. It has been used in dentistry for over 1,000 years to make dental restorations like crowns, bridges and fillings. Gold alloys are classified according to their gold content and properties. Other metals like palladium, silver, copper and platinum are added to gold alloys to increase properties like strength and hardness.
Gold is a soft, shiny yellow metal that is malleable and ductile. It has many industrial and decorative uses in electronics, jewelry, coins and more due to its conductive and corrosion-resistant properties. Iron is the most abundant metal and is used primarily to make steel for construction and machinery. It is found as ore deposits containing iron oxides. Chromite is the only ore of chromium, which is used to make stainless steel and is often found in ultrabasic rocks. Celestite is a mineral containing strontium sulfate and is used in fireworks, alloys and drilling mud.
This document discusses the properties and uses of silver. Silver has been used since ancient times and was first discovered around 3000 BC. It is a soft, white metal that is highly conductive of heat and electricity. Silver is used in many applications such as photography, mirrors, dental fillings, jewelry, and electrical components. It plays an important role in both industry and medicine due to its antimicrobial properties. If silver were to disappear, it would significantly impact electricity production and distribution, photography, and medical equipment and practices.
Gold is a bright yellow metal that occurs naturally in the earth. It has been used for over 5000 years for jewelry, art, and technology due to its attractive color and resistance to corrosion. Gold dissolves in mercury and certain acid solutions, and is used today in dentistry, medicine, electronics, aerospace applications, and sometimes in gourmet foods for decoration due to its inert properties. The major producers of gold are South Africa, Canada, the United States, and Australia.

Metals occur naturally in the Earth's crust and most are found as ores, which are metal compounds. The 6 metals first used by prehistoric humans were gold, silver, lead, copper, tin, and iron. Metals are extracted from ores through smelting and can be further refined. Steel is an alloy of iron with 0.5-1.5% carbon, making it not a pure metal. Metals are strong, conductive materials that are important for tools, infrastructure, and more due to their properties.
Minerals are naturally occurring inorganic solids with definite chemical compositions and ordered atomic structures. They form through natural geological processes on or inside Earth. Key properties used to identify minerals include hardness, luster, specific gravity, streak, and cleavage/fracture. Minerals have many important uses beyond gems, including as sources of useful elements like iron, aluminum, and titanium that are integral to infrastructure, transportation, and technology.
This document discusses factors that affect the price of gold, including global economic crises, inflation, interest rates, and central bank policies. It notes that gold is a finite natural resource, over half of which is used for jewelry. Major consumers of gold include India, China, and the United States. The price of gold fluctuates based on supply and demand dynamics.
The document discusses the process of mining and extracting gold. It describes how gold was originally mined during the 1800s gold rush and is now located using soil sampling. It explains two mining methods - lode deposits where gold is visible in rock and panning where gold accumulates in sediment.

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Current Ms word generated power point presentation covers major details about the micronuclei test. It's significance and assays to conduct it. It is used to detect the micronuclei formation inside the cells of nearly every multicellular organism. It's formation takes place during chromosomal sepration at metaphase.
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skills
2. 1. Gold is a chemical element. Its
chemical symbol is Au and its atomic
number is 79.
3. 2. Compared to other metals,
gold is less chemically
reactive.
4. 3. Gold is a good conductor of
electricity and heat.
5. 4. Gold is shiny, soft and dense. It is
also malleable, which means it can
easily be beaten into thin sheets or
other shapes.
6. 5. Gold is malleable enough for just 1 gram to be
hammered into a sheet 1 square meter in size. It
can also be made so thin that it appears
transparent
7. 6. Due to a similar appearance to
gold, the mineral pyrite has the
nickname fool’s gold
8. 7. The amount of gold in various alloys (a
combination of gold and another metal such as
silver) is measured in carats (k). Pure gold is 24k
9. 8. As of 2009, it has been estimated
that humans have mined around
160000 tonnes of gold.
