Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete. [1] According to their dispersing functionality and action mode, one distinguishes two classes of superplasticizers:
Charcot–Marie–Tooth disease type 2 COFS Cerebro-oculo-facio-skeletal syndrome: COLD Chronic obstructive lung disease: COPD Chronic obstructive pulmonary disease: COVID-19 Coronavirus disease 2019: CP Cerebral palsy: CP/CPPS: Chronic prostatitis/chronic pelvic pain syndrome: CPDD Calcium pyrophosphate deposition disease: CPM Central pontine ...
PVC, used extensively in sewage pipes, is only useful because of plasticizers. [1]A plasticizer (UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
Autoimmune polyendocrine syndrome type 2, a form of autoimmune polyendocrine syndrome also known as APS-II, or PAS II, is the most common form of the polyglandular failure syndromes. [2] PAS II is defined as the association between autoimmune Addison's disease and either autoimmune thyroid disease , type 1 diabetes , or both. [ 5 ]
Patients may experience debilitating spine and hip deformities, carpal tunnel syndrome, and joint stiffness. Patients may be normal height in infancy, but stop growing by the age of two years. They may not reach a height of greater than 4 ft (1.2 m). [citation needed] Other early symptoms may include inguinal and umbilical hernias. These may be ...
Regardless of which, several studies have been performed on superplasticity in doped, fine-grain Al 2 O 3.Demonstrated that the grain size of Al 2 O 3 containing 500-ppm MgO can be further refined by adding various dopants, such as Cr 2 O 3, Y 2 O 3, and TiO 2. A grain size of about 0.66 μm was obtained in a 500-ppm Y 23-doped Al 2 O 3.
There is a lack of wide understanding of the condition and it can be considered a zebra condition. As hypermobility syndrome can be easily mistaken for being double-jointed or categorised as nothing more than perhaps an achy body from lack of exercise, medical professionals may diagnose those affected incorrectly and not adequately investigate ...
Medical care is directed at treating systemic conditions and improving the person's quality of life. Physical therapy and daily exercise may delay joint problems and improve the ability to move. Changes to the diet will not prevent disease progression, but limiting milk, sugar, and dairy products has helped some individuals experiencing ...
