Estimation of Log Volume by Importance Sampling
Forest Science, 1986Abstract Importance sampling is proposed as a technique for estimating log volume that eliminates the bias of conventional methods arising from irregular log taper. In a trial of the technique, the average relative sampling error for individual logs, based on a measurement of one cross-section per log, was 5.2%.

The Importance of Correct Norms in Blood Volume Measurement
The American Journal of the Medical Sciences, 2007Accurate individual norms are required for blood volume measurement to be useful in a clinical setting. The primary physiological determinant of normal blood volume is body composition. Norms have been developed based on weight and body surface area, but these have systematic errors arising from variations in body composition or body size.

Importance of post‐exercise hypotension in plasma volume restoration
Acta Physiologica Scandinavica, 2000The aim of this study was to test the hypothesis that post‐exercise hypotension was the mechanism for the plasma volume and albumin gain during recovery. Seven healthy young men completed two experiments (≥1 week apart) to exercise continuously at 65% of peak aerobic capacity for 60 min followed by the recovery without (experiment 1) or with ...

The importance of volume exclusion in modelling cellular migration
Journal of Mathematical Biology, 2014The modelling of collective migration has traditionally been undertaken in a continuous framework, with little reference to the individual-level mechanisms that give rise to such a concerted movement. One factor whose importance is now coming to light is that the individuals themselves occupy space in the domain, thus obstructing others from moving ...

THE IMPORTANCE OF BLOOD VOLUME CULTURED ON DETECTION OF BACTERAEMIA
Acta Pathologica Microbiologica Scandinavica Section B Microbiology, 1981The effect of culturing 2 and 5 ml of blood in 18 ml of supplemented peptone broth 1 (SPB I) and 45 ml of supplemented broth II (SPB II) respectively, was compared. A total of 204 isolates were recovered from 78 patients. There were 136 isolates recovered from both the 45 and the 18 ml tubes.

Importance of blood volume cultured in the detection of bacteremia
European Journal of Clinical Microbiology & Infectious Diseases, 1989The influence of the volume of blood cultured on the rate of detection of bacteremia was evaluated in a routine 12-tube blood culture system using 1693 samples from 1502 patients. Blood samples were drawn simultaneously into two transport tubes. The blood volume cultured was the only varying parameter.

Importance of volume factors in dialysis related hypertension.
Clinical nephrology, 1997To evaluate the relation between total body water and dialysis related hypertension.Thirty stable chronic hemodialysis patients were studied. Twenty-four-hour ambulatory blood pressure on the day before dialysis, blood pressure before and after dialysis, weight gain, ultrafiltration and total body water were determined. Total body water was measured by

Importance of tumor volume in supraglottic and glottic laryngeal carcinoma
Strahlentherapie und Onkologie, 2013The aim of our study was to assess the prognostic value of tumor volume compared to and in addition to T-stage on local control (LC), disease-free survival (DFS), and overall survival (OS) in glottic and supraglottic laryngeal carcinoma patients.In 150 patients, we determined tumor volume on diagnostic CT scans.

Importance of cytoskeletal elements in volume regulatory responses of trout hepatocytes
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2005The role of cytoskeletal elements in volume regulation was studied in trout hepatocytes by investigating changes in F-actin distribution during anisotonic exposure and assessing the impact of cytoskeleton disruption on volume regulatory responses. Hypotonic challenge caused a significant decrease in the ratio of cortical to cytoplasmic F-actin, whereas

Importance of Volume Factors in Dialysis-Related Hypertension
1991In order to evaluate the influence of volume factors on blood pressure (BP) in 20 chronic hemodialysis patients, we studied the effect of total body water, interdialytic weight gain, hematocrit, erythropoietin, and blood viscosity on BP with predialysis and 24 h ambulatory measurements.
