Needle rotation delivered larger biopsy samples than the standard method. Laitinen provided larger samples than the Nashold needle, with the same sampling method or vacuum pressure. A higher histopathological diagnostic quality of tissue was obtained with the Laitinen needle than with Nashold, with ...
aProbability and non-probability are the two main categories of sampling methods that are used to select respondents to participate in a research. As non-probability sampling might cause sample bias, which would further affect the quality of research findings, probability sampling method is widely us...
Probability sampling method ensures that each individual of the target popular has equal chance to be chosen. The target population of this research is the consumers of online and mobile shopping. Because of the constraint of time and cost, target populat 概率取样方法是用途广泛用不同的研究。
A Method for Mea- suring the Comparability of Different Sampling Methods Used in Biological Surveys: Implications for Data Integration and Synthesis. Freshwater Biology 50:1105-1115.Cao, Y., C. P. Hawkins & A. W. Storey, 2005. A method for measuring the comparability of different sampling ...
In conclusion, rectovaginal sampling increased the number GBS positive women detected, compared to vaginal and/or rectal sampling. Direct plating on CA and/or GBSDA provided rapid detection of GBS that was at least as sensitive and specific as the CDC recommended method of Lim broth subcultured...

method. In step-I, the samples were heated at a heating rate of 5°C/min to an intermediate holding temperature and in step-II, the samples were further heated at a heating rate of 10°C/min to a final temperature. All the samples were furnace-cooled and their heat-treatment conditions...
Randomized controlled trials are the gold standard for measuring causal effects. However, they are often not always feasible, and causal treatment effects
Here we use bladder urothelial carcinoma tissue of two different tumor stages (Ta/T1—non-muscle invasive bladder cancer (NMIBC), and T2/T3—muscle invasive bladder cancer (MIBC)) which, upon sampling, were divided and preserved by FFPE and OCT. Samples were parallel processed from the two ...
Sampling is a process instatistical analysisin which researchers take a predetermined number of observations from a larger population. It allows researchers to conduct studies about a large group by using a small portion of the population. The sampling method depends on the type of analysis being p...
