Rationale: Current studies which use the oxygen isotope composition from diatom silica (18Odiatom) as a palaeoclimate proxy assume that the 18Odiatom value reflects the isotopic composition of the water in which the diatom formed. However, diatoms dissolve post mortem, preferentially losing less silicified structures in the water column and during/after burial into sediments. The impact of dissolution on 18Odiatom values and potential misinterpretation of the palaeoclimate record are evaluated.Methods: Diatom frustules covering a range of ages (6 samples from the Miocene to the Holocene), environments and species were exposed to a weak alkaline solution for 48 days at two temperatures (20 C and 4 C), mimicking natural dissolution post mucilage removal.

Many people use the terms crystal and glass interchangeably when referring to sunglass or eyeglass lenses.

However, they offer crystal sunglass lenses, which are manufactured with a 50/50 mix of glass and polycarbonate.

Tradition dictates that the start of the race is signaled by Laz lighting a Camel cigarette. Runners started trotting past him as he made his first exhale. The course begins with a steady incline that will reach 1,600 feet of elevation within just the first mile and a half or, as Laz described it, easiest hill they do all day.
Unfortunately, many women don include Feminine Hygiene as a proper and dedicated routine in their daily life schedule. The majority of the cysts are harmless and disappear without any treatment. However, in some cases, they indicate health issues that can be as severe as infertility.

The outcome, however, was far different. After years of being diagnosed with everything from early onset dementia to depression, my mother was finally discovered on the floor, looking up at us helplessly, and not knowing who we were or where she was.
