What does CLSM stand for?
Controlled low strength material, abbreviated CLSM, also known as flowable fill, is a type of weak, runny concrete mix used in construction for non-structural purposes such as backfill or road bases.
What is confocal microscopy?
As a distinctive feature, confocal microscopy enables the creation of sharp images of the exact plane of focus, without any disturbing fluorescent light from the background or other regions of the specimen. Therefore, structures within thicker objects can be conveniently visualized using confocal microscopy.
Where is confocal microscopy used?
By scanning across the sample, an image of it can be created. Confocal microscopes are used in the semiconductor industry, as well as in life and material science labs. Confocal microscopy is especially useful in studying live cells.
How does a confocal microscopy work?
A confocal microscope works with a laser and pinhole spatial filters. The laser provides the excitation light, and the laser light reflects off a mirror. The mirrors scan the laser across the sample. The dye and the emitted light get descanned by the mirrors that scan the excitation light.
What is flowable concrete?
Flowable concrete, which is also sometimes referred to as flowable fill, is similar in nature to the composition of lean concrete. It can be used to quickly and easily fill cavities. Its low strength and self-leveling capabilities contain strength of between 30 and 150 lbs per square inch.
What is CDF concrete?
1.01 DESCRIPTION Control Density Fill (CDF) is used as a low strength, self consolidating fill material for confined spaces which can be easily excavatable at a later time. CDF is characterized by a high maximum slump of 8 inches. CDF is not a structural concrete and should not be used in such applications.
Why is it called confocal microscope?
In contrast, a confocal microscope uses point illumination (see Point Spread Function) and a pinhole in an optically conjugate plane in front of the detector to eliminate out-of-focus signal – the name “confocal” stems from this configuration.
What is AFM technique?
Atomic force microscopy (AFM) is a powerful technique that enables the imaging of almost any type of surface, including polymers, ceramics, composites, glass and biological samples. AFM is used to measure and localize many different forces, including adhesion strength, magnetic forces and mechanical properties.
Why is it called confocal microscopy?
What is confocal principle?
The basic principle of confocal microscopy is that the illumination and detection optics are focused on the same diffraction-limited spot, which is moved over the sample to build the complete image on the detector.
How does a Clsm work?
The CLSM works by passing a laser beam through a light source aperture which is then focused by an objective lens into a small area on the surface of your sample and an image is built up pixel-by-pixel by collecting the emitted photons from the fluorophores in the sample.
What is lean Crete?
Lean concrete is made up of low cementitious material content. It is primarily poured through chutes, conveyor buckets, or pumps. It is used in various areas where support and strength are not critical. The mixture is highly liquid when compared to real concrete and is self-leveling, making it ideal for saving time.
What can CLSM be used for in the real world?
CLSM combines high-resolution optical imaging with depth selectivity which allows us to do optical sectioning. This means that we can view visual sections of tiny structures that would be difficult to physically section (e.g. embryos) and construct 3-D structures from the obtained images.
What are the synonyms for the word analysis?
Words Related to analysis. assessment, diagnosis, evaluation, examination, inspection, investigation, muster, scrutiny. arrangement, assortment, cataloging (or cataloguing), categorization, classification, codification, indexing. enumeration, inventory, itemization, tabulation.
How is a CLSM based on a conventional microscope?
The CLSM is based on a conventional optical microscope but instead of a lamp, a laser beam is focused onto the sample (Figure 1). The intensity of the laser light is adjusted by neutral density filters and brought to a set of scanning mirrors that can move them very precisely and quickly.
What is guide specification for controlled low strength materials ( CLSM )?
2 1.0 SCOPE 1.1 R1.1This specification covers Controlled Low Strength Materials, CLSM,guide to engineers, architects and specifiers that have manufactured and delivered to a purchaser in a freshly mixed and unhardened state.(CLSM), commonly called flowable fill.
