Minerals are naturally occurring inorganic solids with a definite chemical composition and structure. They can exist as elements like gold or silver or as compounds like oxides, carbonates, and silicates. Minerals form in two ways - elements exist freely in nature while compounds form through the combination of elements and minerals.
The document discusses the composition of the Earth's crust at different scales, from the global scale down to the atomic scale. It focuses on the eight most common elements in the crust - oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. These elements form minerals by bonding together at the atomic level. Minerals are the building blocks of rocks. Many important rock-forming minerals are silicates that are made up of silica tetrahedra bonded together in different arrangements. Common silicate minerals include olivine, pyroxenes, amphiboles, micas, feldspars, and quartz.

The rock cycle describes how rocks continuously transform between these types through geological processes.
Bowen’s Reaction Series
ROCKS:
There are three kinds of rocks, that are defined on the basis of how they formed.
Igneous Rocks:
are formed from the solidification of molten rock or magma.
Sedimentary Rocks:
form through when materials at the earth's surface (sediments) are buried and hardened (lithified).
Metamorphic Rocks:
are formed when older rocks are changed by heat and pressure without being melted.
The document discusses mineral resources and their properties. Minerals are solid, inorganic substances that form in nature through geological processes. They are made up of elements like silicon, oxygen, iron and aluminum. Minerals have distinct physical properties depending on their chemical composition and crystalline structure, such as hardness, color, luster, cleavage and solubility. These properties determine a mineral's various industrial and commercial uses like abrasives, pigments, insulation, and conducting or storing electricity, heat, and magnetism. Minerals are an important source of elements and understanding their properties is key to utilizing mineral resources.
1) Ores form through geological processes that concentrate elements and minerals within rocks.
2) Common concentration mechanisms include weathering and erosion, precipitation from aqueous fluids, liquid immiscibility in magmas, and oxidation/reduction reactions in groundwater.
3) These processes remove elements from source rocks, transport them through fluids like water or magma, and re-deposit them in concentrated forms in favorable locations, creating economically viable ore deposits.
Graphite was discovered in Borrowdale, England in the 1500s. Early users wrapped graphite sticks in string to strengthen them for writing. Over time, people began putting graphite sticks in wooden casings to create the modern pencil. Minerals are found in many everyday items like pencils, sidewalks, homes, and tables. A mineral has four key properties - it must be natural, inorganic, solid, and have a definite crystalline structure and chemical composition. Minerals are categorized as silicates, which contain silicon and oxygen, or non-silicates like carbonates, oxides, and sulfides.
The document discusses the two main groups of minerals: silicate minerals and nonsilicate minerals. Silicate minerals make up over 90% of the Earth's crust and contain silicon and oxygen atoms. Nonsilicate minerals, which comprise 8% of the crust, do not contain silicon and oxygen and include economically important resources such as metals, gems, and precious metals. Both silicate and nonsilicate minerals form through geological processes of cooling molten rock.
Minerals are naturally occurring, crystalline solids that are nonliving. They are divided into two main groups: silicates and non-silicates. Silicates make up about 90% of minerals and contain silicon and oxygen, while non-silicates do not contain these elements. Common silicate minerals include quartz, mica, feldspar and olivine, and non-silicates include native elements, carbonates, halides, oxides, sulfates and sulfides.

Major soils in India include alluvial soils covering 75 Mha, black soils covering 72 Mha, red soils covering 70 Mha, laterite soils covering 25 Mha, and saline/alkali soils covering 7.5 Mha. Alluvial soils are the most fertile and important for agriculture. Black soils are very dark in color and develop deep cracks. They are classified as vertisols. Red soils get their color from iron oxide coatings. Laterite soils form in tropical climates and are high in kaolinite clay. Salt-affected soils occur in arid regions where salts accumulate due to evaporation. Forest soils include podzolic soils found under coniferous vegetation and brown forest soils developed on
Soil erosion is defined as the detachment, transportation, and deposition of soil particles by forces like water, wind, waves, and gravity. There are three main steps: 1) detachment of soil particles from the main body, 2) transportation by splashing, floating, or rolling, and 3) deposition in another place. Geological erosion refers to natural erosion caused by water, wind, gravity, and glaciers, while accelerated erosion exceeds the normal rate and becomes destructive due to factors like climate, topography, soil characteristics, ground cover, and land use. The Universal Soil Loss Equation is used to estimate soil and water erosion and considers rainfall, soil erodibility, slope length, slope gradient, crop management,

For each order it provides the root of the name and a brief description of the key features used to classify soils into that order.
The document provides information about the composition and structure of the Earth. It discusses three main spheres - the lithosphere, hydrosphere, and atmosphere. The lithosphere is the solid crust and interior of the Earth. The hydrosphere is the sphere of water surrounding the Earth. The atmosphere is the gaseous envelope surrounding the lithosphere and hydrosphere. It also describes the internal structure of the Earth including the core, mantle and crust, and provides details on the composition of each sphere.
Rocks can be divided into three main classes based on their mode of formation:
1) Igneous or primary rocks such as basalt and granite form by the cooling and solidification of magma either underground or on the surface.
2) Sedimentary or secondary rocks like sandstone and limestone form by the compaction and cementation of sediment.
3) Metamorphic rocks such as gneiss, schist, and marble form by the alteration of pre-existing rocks due to heat, pressure, and chemical changes.
The document discusses various nitrogenous, phosphatic, potassic, and micronutrient fertilizers including their chemical compositions and percentages of nutrients. Nitrogenous fertilizers mentioned include urea, ammonium sulfate, calcium ammonium nitrate, and slow release varieties. Phosphatic fertilizers include single super phosphate, triple super phosphate, and rock phosphate. Potassium chloride and potassium sulfate are listed as potassic fertilizers. Common micronutrient sources and chelating agents are also outlined.
Organic farming utilizes techniques like crop rotation and organic manures to nourish soil fertility. Crop rotation, the recurrent succession of crops on the same land, improves soil structure and nutrients while suppressing weeds and pests. Organic manures, including bulky manures like farm yard manure and compost, as well as concentrated manures from oilcakes, are also used to increase soil nutrients. Vermicompost and other composts are additionally employed in organic agricultural practices.
Tillage is the physical manipulation of soil using tools and implements to improve soil tilth for better plant growth. Primary tillage implements include the mouldboard plough, disc plough, and reversible plough, while secondary tillage implements are cultivators, harrows, and seed drills. Tillage aims to create good soil structure and control weeds through mulch tillage.
Dragon fruit, also known as pitahaya, has several health benefits. It is rich in antioxidants, vitamins, minerals, and fiber which can help fight diabetes, reduce inflammation, and promote digestive and heart health. Dragon fruit is cultivated as both an ornamental plant and fruit crop. It grows best in tropical climates with temperatures between 20-30 degrees Celsius and at least 50cm of annual rainfall. Propagation is usually through cuttings, and plants are spaced 2 meters apart in pits filled with soil and compost. Dragon fruits are harvested 1 month after flowering from August to December, with average yields of 5-6 tonnes per acre.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
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.
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.
Exposé invité Journées Nationales du GDR GPL 2024
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.

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.
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.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
2. Rock forming minerals:
Minerals are solid substance and composed of atoms having
an orderly and regular arrangement.
A Minerals is a naturally- occuring ,homogeneous element or
inirganic compound.
Most minerals are composed of two or more elements that
combine to form a compound such as gypsum :
CaSO4.2H2O, Olivier, feldspar etc.
3. Formation of minerals:
When the molten magma solidifies,the different element
present therein freely arrange themselves in accordance with
the attractive forces and geometric form.
Arrange only 4 oxygen anions(with a radius of 1.32 A°)
around a central silicon action (with a radius of 0.42 A°) ,this
is the arrangement of a tetrahedron.
7. Secondary clay minerals:
Na,K,Ca,Mg,Fe,Al,OH other then Si and O.
In the Absence of a crystalline form, the material is
termed as non- crystalline e.g., allophone,chalcedony.
8. Primary minerals:
The primary minerals are those which are formed owing to the
crystallization of molten magma.
Orthosilicates
Phyllosilicates
Inosilicates
Tectosilicates _Quartz
_Feldspar.
9. Inosilicates:
The simplest way to link tetrahedron is to join
one corner with another forming a single chain
structure is PYROXENE.
10. Double chain inosilicate:
Complex way to link tetrahedron is when two single-chains
are cross –linked to make a double – chain structure,e.g.
AMPHIBOLES
11. Phyllosilicates:
A complex linkage is in the sheet
structure in which all tetrahedra share
three oxygen ions with the
neighbouring tetrahedra.
14. Phyllosilicates:
They have sheet structure of tetrahedra where each silicon
ion shares three oxygen ions with adjacent silicon ion to
form a pattern ,like honey –comb.
15. Orthosilicates:
The orthosilicates are represented by olivine(Fe,Mg)2 SiO4.
The structure consists of individual silicon –tetrahedra
alternating with positively – charged metal ions which
balance the negative charge of the tetrahedra units.
17. Tectosilicates:
All four oxygen of the silica tetrahedron are shared by the
neighbouring silicon tetrahedra.this means that there are two
ions of oxygen for every ion of silicon thus forming a 3-
dimensional framework.it is represented by the formula SiO2.
Quartz,feldspar.
18. Quartz:
The framework of quartz is very
density packed and occurs in a
high degree of purity.
It is strongly resistant to physical and
chemical weathering as the structure is
densely packed,electrically neutral and
prevents any form of substitution.
19. Feldspar:
In feldspar,the basic structure is of ring
type,made up of four tetrahedra.
Depending upon the presence of
diagnostic ions,like K,Na and Ca,that
balance the electric charge,feldspar
are named as orthoclase,albite and
anorthite etc.
20. Some important primary rock forming
minerals:
FERROMAGNESIAN:

•Orthoclase Pink (flesh)
•Anorthite White to dark-grey
•Quartz Cloudless to grey.
22. Secondary minerals:
The secondary minerals are formed at the earth’s surface by
weathering of the pre-existing primary minerals under
variable conditions of temperature and pressure.
During weathering water accompanied by CO2 from the
Atmosphere plays an important role in processes, such as
hydrolysis, hydration and solution.
23. Some important secondary minerals:
Silicates:
●clay minerals - ittlite ,kaolinite,montmorilonite etc.

●Carbonated: Calcite,dolomite.
●Sulphates : Gypsum
●Phosphate : Apatite,Rock phosphate.
24. Clay minerals:
The secondary minerals dominantly occurred in the clay
fractions of almost all soils in sedimentary rocks,especially
shales.
Of the naturally –occurring inorganic crystalline minerals
found in the clay fraction of soils,the most commonly
observed are layer silicates(illite,
montmorilonite,chloride,vermiculite,kaolinite).
25. Classification of minerals:
