Refractometers are commonly used to determine urine specific gravity (SG) in the assessment of hydration status and urine specimen validity testing.
When a story – a big story – appears, there is an initial buzz of conversation, a quick assessment of the gravity of developments.
Although an approximate assessment of specific gravity can be obtained by the hefting of a hand specimen of a specific monomineral, an accurate measurement can only be achieved by using a specific gravity balance.
Measurements of repeat gravity are pertinent to the assessment of natural recharge into the reservoir and its increase in response to production-induced pressure decline (Hunt, 1970; Geri et al., 1985; Allis and Hunt, 1986; Nordquist et al., 2004).
All of the patients in the studied group had normal results of measurements of blood pressure, kidney ultrasounds, and general urinalyses with assessment of specific gravity and pH.
However, a rigorous assessment of the Japanese gravity data may be necessary in the future.
Upon arrival to the laboratory participants voided their bladder to provide a sample for assessment of urine specific gravity (USG; Visual Refractometer, Index Instruments, Cambridge, UK) and osmolality (Osmocheck, Vitech Scientific, Partridge Green, West Sussex, UK).
All patients underwent blood pressure screening, kidney ultrasound, and general urinalysis, with assessments of urine specific gravity, pH, presence of glycosuria, and proteinuria.
Participants differed in the assessment of the extent and gravity of emigration.
The emergence of the group in central Sulawesi Province, which has been racked by Christian-Muslim violence, "suggests a need to revise assessments about the nature and gravity of the terrorist threat in Indonesia," Ms. Jones wrote in the report.
