From [gamma](r), the basic parameters of the lamellar stacks, to know the crystalline
lamellae thickness ([l.sub.c]) and the amorphous layer thickness ([l.sub.a]), have been calculated.
On Earth, when water molecules reach zero degrees Celsius, they enter a lower energy state and settle onto a hexagonal crystalline
The effective date of the rule was April 23, 2018, and the compliance dates are as follows: For occupational exposures to respirable crystalline
silica in construction work, employers must comply with all obligations of the rule by October 1, 2018.
One important change from the proposed rule is that OSHA has made a final determination to exclude exposures in general industry and maritime where the employer has objective data demonstrating that employee exposure to respirable crystalline
silica will remain below 25 [micro]g/[m.sup.3] as an eight-hour TWA under any foreseeable conditions.
Clinical biochemical and pathologic correlations in Bietti's crystalline
dystrophy Am J Ophthalmol.
Chronic/classic silicosis, the most common, occurs after 15-20 years of moderate to low exposures to respirable crystalline
When I was working on Gnegel's crystalline
glaze team I was full of complaints regarding the complicated and difficult experiments.
Due to its easy exploitation and good quality, when compared with water stored in crevices of crystalline
rocks, the water from the alluvial aquifer of the Forquilha River becomes an important source for both human and animal consumption, as well as to irrigate small plantations, such as maize and bean.

In semi-crystalline thermoplastics, because of the different densities of the amorphous and crystalline
regions, and hence different refractive indices, transmitted light gets diffracted and _ scattered as it passes from one region to the next, thereby reducing the amounted of light transmitted in the normal direction.
Metallic glasses (MGs) are a kind of advanced engineering materials due to their high strength, high elastic limit, and better corrosion resistance compared to their crystalline
The surface properties of a bacterium are determined by the exact molecular composition of its membrane and cell envelope, including capsules, glycocalyx, Crystalline
Layer, peptidoglycan and LPS, and the other surface structures, such as flagella and pili or fimbriae [7,17,3].
SIMON Ellis, a respiratory disease solicitor at Hugh James, discusses how exposure to crystalline
silica dust through working with fine particles of sand, cement or limestone may be the emerging respiratory disease in the workplace.
