Carbon Skeletons

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side chains...

Carbonation Shrinkage

Carbonation Shrinkage

Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction facilitates the...

Carbon-dioxide Fixation

Carbon-dioxide Fixation

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Collar Bearings

Collar Bearings

Collar bearings are essential in various machines designed to support axial loads on rotating shafts. Depending on the specific application and requirements, they can be found with single or multiple collars.

Bearing Stress

Bearing Stress

Bearing stress refers to the contact pressure between two separate bodies. To visualize this, imagine a bolt thrust through a plate. The bolt applies a force to the plate, which exerts an equal but opposite force back onto the bolt. This force isn't just a singular entity but a compilation of numerous smaller forces distributed across the contact surface between the bolt and the plate.
Due to the intricacy of these microforces, an average value, known as bearing stress, is often used by...

Area of Science:

Orthopaedics
Biomedical Engineering

Background:

The CMCR brace is an innovative, monoshell orthosis for progressive scoliosis treatment.
It utilizes adjustable, mobile polyethylene and carbon supports, differing from rigid, fixed-support braces.
Designed for young patients and reducible scoliosis in older teenagers, it aims to preserve chest growth and mobility.

Purpose of the Study:

To evaluate the effectiveness of the CMCR brace in treating progressive scoliosis.
To assess the impact of the CMCR brace on vital capacity and patient comfort.
To compare the CMCR brace with traditional rigid braces for scoliosis management.

Main Methods:

Two studies analyzed CMCR brace effectiveness: a retrospective study of 115 patients and a cohort study of 90 patients.
Evaluations included spinal stabilization, hump reduction, and vital capacity (VC) measurements.
3D analysis was used to refine brace design and correction force application.

Main Results:

The initial study showed CMCR brace stabilized moderate scoliosis but decreased VC by 13%; treatment was more effective in Risser 3-4 patients.
Modifications improved dorsal pad pressure and force localization.
The second study demonstrated increased VC (21% from initial) after treatment, exceeding theoretical growth (18%), indicating good patient acceptance.

Conclusions:

The CMCR brace is a viable orthopaedic treatment option for teenagers with scoliosis.
It offers improved mobility and potentially better quality of life compared to rigid braces.
Further research may refine its application for optimal scoliosis correction and respiratory function.
