Study of Fiber Reinforced Polymer Materials in Reinforced Concrete Structures...Girish Singh
Around the world we are having several upcoming projects near the coast line so the study is needed to understand the effect on cost when we use FRP in the structure because FRP is a costly material compare to steel which may or may not increase the structure overall cost.
It will may or may not increase the structure cost because if we use FRP in a structure then we can avoid the problem that we face in a structure caused due to corrosion which reduce strength of the structure, foundation loosing plaster from the surface of the reinforced section due to expansion caused due to rusting as well as in building envelopes.
The objectives of this seminar report are to study about FRP Manufacturing and its properties, study about the various applications of FRP, design and analyze a FRP member, Finite element analysis of a simple beam using FRP as a reinforcement, role of FRP in the sustainable world, to find out the cost benefit of the elements used in a corrosive environment structure which can be replaced by the FRP.
This study will cover all the forms of FRP that can be used in a building and give a brief about FRP rebars its properties, design, analysis, uses and the effect on cost of a build during construction as well as the cost analysis of the structure.
This study will give an idea on the advantage of FRP over steel when we are using FRP in a corrosive environment like coast line and it will give an initial idea to the designer about the advantage and disadvantage of FRP over steel.
In the final part of this seminar report analysis results are used to give a base that FRP can sustain in structure as FRP reinforced bar and an example of a LCC is also used to give a satisfactory conclusion and on the final page the summery of the seminar is present.

School: Al Wakra Independent School for Girls
Composites Module: Students discover what composite materials are and test them to learn their advantages over pure materials. Finally, at the end of the workshop, they design new composite materials.
This project: Students design fire Jacket that help children during fire rescue.
Composites are made by combination of two or more natural or artificial materials to maximize their useful properties and minimize their weaknesses.
Example: The oldest and best-known composites,
Natural: Wood combination of cellulose fibre provides strength and lignin is the "glue" that bonds and stabilizes. Bamboo is a very efficient wood composite structure.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
5. MATERIALS
RESINS
• Used as base material for
reinforcement layer.
• Transfer stress between
reinforcing fibres and to
protect them from
mechanical and
environmental damage.
REINFORCEMENT
• Glass fibre is the
reinforcement in this plastic
6. FIBRE GEOMETRY
ALLIGNED FIBRES
• In this type of alignment, the fibres are woven parallel to each
other
• In this type of alignment, the fibres are woven randomly
according to a specific density.
• In this type of alignment, the fibres are woven in the shape of a
net. It is the strongest among the three.
RANDOM FIBRES
WOVEN FIBRES
7. MANUFACTURE
• Plastic is manufactured by addition polymerization and step
growth polymerization .
• It is known as matrix.
• The plastic which is under polymerization is mixed with glass
fibre, enhance the strength and elasticity of the plastic.
• This results in the formation of Glass Fibre Reinforced Plastic
(GFRP)
8. Applications
GFRP can be used for both interior and
exterior fixtures in a variety of shapes, styles,
and textures; in new buildings or restorative
projects.

9. ARCHITECTURAL USES AND
ADVANTAGES:-
- Due to its translucent nature and less weight, it is used as a roofing material in
various places . It also helps to allow only partial light through it.
- Due its cost efficiency, it is even used as partitioning material between two spaces.
- It can be easily shaped due to its more elasticity.
- It is a good heat resisting material.
- Has a very high strength to weight ratio
- Low weights of 2 to 4 lbs. per square foot means, Faster installation, less structural
framing, and lower shipping costs

salts, and most chemicals
- Domes and cupolas are resigned together to form a one-piece, watertight,
structurable to Mold Complex Shapes Virtually any shape or form can be
molded
