There are two types of fibres - natural fibres obtained from plants and animals like cotton, jute, silk and wool, and synthetic fibres created by humans using chemicals like acrylic and polyester. The life cycle of silkworms and process of obtaining silk is described. Different plant fibres, cotton processing including ginning, spinning and weaving, and types of fabrics are also outlined.
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.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
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.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
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.

Nucleophilic Addition of carbonyl compounds.pptxSSR02
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.

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.
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.
8. • Natural fibers are those that occur in fiber form in nature
• Traditionally, natural fiber sources are broken down into animal, plant, or
mineral
• Fibers from plant or vegetable sources are more properly referred to as
cellulose-based and can be further classified by plant source
• They may be separated from the plant stalk, stem, leaf, or seed.
• Fibers from animal sources are more properly known as protein-based
fibers.
• They are harvested from an animal or removed from a cocoon or web.
• Mineral fibers are those that are mined from the earth.
• Except for silk, all-natural cellulose- and protein-based fibers are obtained
in short lengths and are called staple fibers.
• Silk is a continuous filament fiber.
9.
10. Plant fiber
Cellulose-based fibers consist of bast, leaf, and seed-hair fibers.
Bast fibers come from the stem of the plant and include flax, hemp, jute, and ramie.
Leaf fibers are stripped
from the leaves of the plant and include manila and sisal.
Seed-hair fibers are collected from seeds or seed cases and include cotton and kapok.
11. Cotton (seed)
obtained from the cotton seed, is the best-known and most-used natural cellulosic fiber.
Cotton is a natural fiber (vegetable fiber) obtained from the seed of the cotton plant.
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective capsule, around the
seeds of cotton plants of the genus Gossypium in the family of Malvaceae.
The fiber is almost pure cellulose.
Under natural conditions, the cotton bolls will tend to increase the dispersion of the
seeds.
12. Flax (bast)
Flax is the bast fiber of the flax plant, used to make linen fabric.
The plants are cultivated and grown in such a way as to produce long, thin stems.
The plant is pulled from the ground for processing.
The non-fibrous material in the stem is rotted away in a process called “retting.”
Once retting is complete, the fibrous mass is rinsed and dried.
The fiber is separated from the woody portion of the decomposed material by breaking and
“scutching” (scraping).
“Hackling” refers to combing the scutched fibers to separate the long and short fibers.
The fiber is then spun, and S-twist is inserted, to produce linen thread.
13. Hemp(bast)
Hemp is a coarse, durable bast fiber from the plant Cannabis sativa.
It is processed into a usable fiber in the same way as flax.
It is used primarily for industrial and commercial textiles, especially cords, twine, and rope.
including jeans, shirts, dresses, hats, bags, ropes and canvas, skin care products, building
materials, paper and many food products
14. Jute (bast)
is a bast fiber from the stem of plants in the genus Corchorus, processed in the same way as
flax.
It widely used for industrial end uses such as sacking, burlap, twine, and backing for tufted
carpets.
15. Kapok (seed)
Kapok is from the seed pods of the Java kapok tree (Ceiba pentandra).
The seed pod is similar to the cotton boll; however, the dried fibers are easily shaken off
the seed.
A buoyant fiber, kapok is used primarily in life jackets, as special stuffing for pillows, and
in some mattresses.
It is not spun into yarn.
16. Manila
Manila is from the leaf stalks of the abaca plant (Musa textilis).
The fibers are separated from the fleshy part of the leaf stalk. Manila is generally used in
rope and cordage.
17. Ramie(bast) Ramie is a bast fiber from the stalk of the ramie plant (Boehmeria nivea), also
known as “China grass.”
The plant is a perennial shrub that can be cut several times a year once mature.
The cut plant’s stalks are peeled or retted to remove the outer woody covering,
revealing the fine fibers underneath.
Degumming removes pectins and waxes, followed by bleaching, neutralizing,
washing, and drying.
The fiber is similar to flax, but more brittle.
Ramie can be spun alone or with other fibers, especially cotton.
18. Sisal ( leaf)
Sisal is from the leaves of plant Agave sisalana.
The leaves are cut when the plant is about four years old, and the fibers are separated from
the fleshy part of the leaf.
Sisal has industrial uses, most commonly as a rug or carpet backing.
19. Coir
fibre from the outer husk of the coconut, used in potting compost and for making
ropes and matting.
20. Piña
Piña is a traditional Philippine fiber made from pineapple leaves.
Pineapples were widely cultivated in the Philippines since the 17th century for
weaving lustrous lace-like luxury textiles known as nipis fabric.
21.
22. ANIMAL FIBRE
Protein-based fibers are from animal sources, most commonly the hair of the animal.
Animal-hair fibers are long-staple fibers, ranging in length from 2.5 to 10 inches or more.
Silk is a natural protein fiber extruded by the silk worm. With a length of over 500 yards, it
is classified as a filament fiber.
23. Wool
Wool is a fine hair fiber from sheep.
In labelling, the term “wool” also may be used to identify fibers from other fleece animals,
such as the Angora goat, Cashmere goat, camel, alpaca, llama, and vicuña.
24. Alpaca wool
• the long, fine hair fiber from the alpaca,
which is a relative of the camel native to
South America.
• It is shorn from the animal once every two
years.
• The soft, fine undercoat is used in textiles.
25. Angora wool
is the long, fine hair fiber from the
Angora rabbit.
It is not to be confused with the hair
fiber of the Angora goat, the source of
mohair.
Angora rabbits are raised domestically.
The fur is combed and clipped from the
rabbit every three months.
26. Bactrian camel
Camel hair comes from the.
The fiber is shed, and about 5
pounds (2.7 kilograms) is
produced per camel.
The under hairs are used in
textiles, and the coarse outer
guard hairs are used in paint
brushes and other non-
apparel uses.
27. Cashmere
is the soft hair fiber from the cashmere
(Kashmir) goat.
The fiber is harvested by combing the
animal.
A single goat produces only about 4
ounces (114 grams) of fiber a year.
Cashmere is considered a luxury fiber.
28. Mohair
Mohair is the long, straight, fine hair fiber
from the Angora goat.
The fiber is usually sheared from the animal
twice a year.
29. Vicuña
Vicuña is the hair fiber from a small
non-domesticated llama-like animal
about the size of a dog.
The animal lives at elevations above
16,000 feet in South America and has
been
listed as endangered since 1969.
Vicuña is the softest of the fleece
fibers.
31. Silk
Silk is a natural protein secreted by the larvae
of several moth species.
The larvae use the filaments to construct a
cocoon, from which the silk is extracted.
Twin filaments of the protein fibroin is
secreted and bound together in a single strand
with the protein gum sericin.
During processing, the sericin is removed,
leaving the fibroin protein.
Cultivated or cultured silk is produced in very
controlled conditions of environment and diet.
Tussar or wild silk is harvested from natural
sources.
32.
33. MINERAL FIBERS
These are the inorganic materials shaped into fibres.
Asbestos is an example of mineral fibre.
These fibres are fireproof, resistance to acid so that these fibres mainly used for the
industrial application.
Examples of mineral fibers are Asbestos, graphite, and glass
34.
35.
36. MAN-MADE FIBER
Synthetic or man-made fibers generally come from synthetic materials such as
petrochemicals. But some types of synthetic fibers are manufactured from natural
cellulose; including rayon, modal, and the more recently developed Lyocell. Cellulose-
based fibers are of two types, regenerated or pure cellulose such as from the cupro-
ammonium process and modified or derivatized cellulose such as the cellulose acetates.
As the name itself indicates these textile fibres are made by man to meet the particular
requirements.
The chemical composition, structure, and properties are significantly modified during the
manufacturing process.
37. Depending on the raw material chosen for making these textile fibres can be further sub-
classified into 3 categories-
1. Regenerated/Man-Made
2. Synthetic Fibres
3. In-Organic Fibres
38. REGENERATED FIBERS
Regenerated synthetic textile fibres are also called as semi-
synthetic fibres.
These fibres are made up of naturally long chain polymer structure,
which is modified and partially degraded by a chemical process to
enable the polymerization reaction to form the fibres.
Most of the semi-synthetic fibres are called cellulose regenerated
fibres.
Examples – Viscose rayon, modal, cupra (Rayon), bamboo,
viscose, Tencel.
The cellulose required comes from various sources such as rayon
from the tree wood, modal from the beech trees, seacell from
seaweed.
In the manufacturing process of these fibres, cellulose is fairly
reduced to the pure viscose form and then foam and then foamed
into the fibre form by extrusion through the spinnerets.
39.
40. Synthetic Fibre
Synthetic fibres are manufactured from the
petrochemicals.
Examples – Polyester, nylon, acrylic, etc.
These fibres are formed by the polymerization of
monomers. Once the polymer is formed, it can be formed
into a filament by converting that polymer into fluid form
and then extruding the molten or dissolved polymer
through narrow holes to give filaments. To form the fibre
from molten polymer it gets passed through the spinneret.
An alteration in structure, design and in other words –
aspects of yarn can be done by altering the polymers used
for it.
These fibres are generally very strong, fine and durable
with very low moisture absorbency property so that these
fibres are also called as hydrophobic fibres.
41. In-Organic Fibre
These textile fibres are also called as metallic
fibres.
Metallic fibres are drawn from the ductile
metals such as copper, gold, silver and can be
extruded or deposited from more brittles such
as nickel, aluminium, and iron.
From stainless steel also fibres can be
formed.
These fibres are not that much widely used
but these fibres have their special
applications in technical textile.
