Nickel is a silvery-white metal that is commonly found in ores containing other elements. There are two important types of nickel ores - laterites, which are oxide or silicate ores predominantly found in tropical regions, and sulfides which contain about 1.5% nickel associated with other metals in more temperate areas. Nickel is extracted from these ores using pyrometallurgical or hydrometallurgical approaches depending on the specific mineral composition of the ore. Once extracted, nickel can be further refined to high purity using techniques like the Mond process or electrorefining.
Metals and non metals
Metals and non-metals have unique properties. Sodium and potassium have low melting points while mercury is liquid. Most metals like gold and silver are malleable and ductile, allowing them to be formed into wires. Electric wires are coated in plastic to prevent electric shock from conduction. Non-metals like carbon exist in different allotropes with varying properties. Metals react with oxygen to form metal oxides, and react with water to form metal hydroxides and hydrogen gas. More reactive metals can displace less reactive metals from their salt solutions. Metals are extracted from ores through processes like enrichment, roasting, and electrolytic refining.

Manganese nodules are rock concretions found on ocean floors that form over millions of years around a core. They consist of layers of manganese, iron, silicates and hydroxides precipitated from seawater. There are three main theories for their origin: weathering of volcanic material, hydrothermal vents, or bacterial activity. They occur in abyssal plains at depths of 4,000-6,000 meters and contain valuable metals like manganese, iron, nickel, copper and cobalt. India has exploration programs to assess extracting polymetallic nodules from the Central Indian Ocean Basin for industrial applications.
Chemistry project
1. The document discusses the processes involved in isolating elements from minerals and ores, including concentration, extraction of crude metal, and reduction.
2. Concentration involves removing unwanted materials (gangue) from the ore using methods like hydraulic washing, magnetic separation, and froth flotation.
3. Extraction of crude metal involves converting the concentrated ore into an oxide through calcination or roasting, then reducing the metal oxide to extract the pure metal using a reducing agent like carbon.

(1) Compression molding is a manufacturing process used to mold thermosetting materials under heat and pressure in a mold cavity.
(2) The process involves preheating the molding material, placing it into the mold, applying pressure using a hydraulic press, and allowing the material to cure.
(3) Compression molding is commonly used to make electrical parts, dinnerware, gears, buttons, and automotive and medical components. It allows for high volume, low-cost production with minimal material waste.
GDT Runout Tolerance
Runout tolerances are used to control the location of circular features relative to a datum axis by specifying allowable variation as a part is rotated. There are two types of runout tolerance: circular runout controls variation at individual cross-sections, while total runout controls cumulative variation along the entire feature. Both reference cylindrical features to a center datum axis and require an RFS material condition for inspection, which involves rotating the part and measuring variation perpendicular to the datum.

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
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.

Applied Science: Thermodynamics, Laws & Methodology.pdf
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.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Magnesium - Engineering Material
- 1. Introduction • Magnesium is a chemical element with the symbol Mg and atomic number 12. • Its common oxidation number is +2. • It is an alkaline earth metal and the eighth-most-abundant element in the Earth's crust • Due to magnesium ion's high solubility in water, it is the third-most- abundant element dissolved in seawater. • The sea contains trillions of tonnes of magnesium, and this is the source of much of the 300,000 tonnes now produced annually. • It has the melting point at 650.0 °C and boiling point at 1107.0 °C
- 2. Production Of Magnesium • A wide variety of production methods can be used to refine magnesium metal. • This is due to both the fact that magnesium is so abundant, making production in many locations possible. • Traditionally magnesium is produced from dolomite and magnesite ore, as well as magnesium chloride. • Electrochemical processes are used to extract the metal from dolomite and magnesite ore.
- 3. • When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. • Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride. • This can be electrolyzed, releasing magnesium, which floats to the surface. • Magnesium is also extracted from salt brines, which contain about 10 percent magnesium chloride. • The magnesium chloride at these sources still contains significant amounts of water and must be dried before it can be electrolyzed to produce metal.
- 5. Electrolysis Of Magnesium • Magnesium is obtained principally by electrolysis of fused magnesium chloride from brines, wells, and sea water. • At the cathode, the Mg2+ ion is reduced by two electrons to magnesium metal: Mg2+ + 2 e− → Mg • At the anode, each pair of Cl− ions is oxidized to chlorine gas, releasing two electrons to complete the circuit: 2 Cl− → Cl2 (g) + 2 e−
