We describe our experience from different angles including the use of multiple sites to achieve adequate sample size, standardizing diagnosis of disease, identifying cancer cases at the time of diagnosis, control selection procedures, logistics of study implementation, questionnaire development and interviewing, biologic specimens, and procedures for protection of human subjects.
The purpose of this study is to confirm if SWETZ is a better alternative than LLETZ (used as a type 3 excision of the TZ) concerning the reduction of incomplete excision (compromised surgical margins) of type 2 or 3 TZ and the morbidity related to the surgery and other variables of clinical interest: procedure related bleeding, fragmentation of the specimen and procedure time.
Specimens and test procedures were designed in accordance with ASTM E399 and ASTM E647 standard.
To improve sensitivity, multiple specimens and concentration procedures, as well as a variety of staining methods, are needed to achieve ample sensitivity [ 13, 14].
Whereas these initial results highlight potential subtype differences, a more definitive analysis (beyond the present scope) should be based on a large number of subtype D and A1 specimens, and estimation procedures specifically adapted to this stratification.
The general limits of (L_i r,theta,phi )) are given as: begin{aligned} lim _{rrightarrow 0} L_{i}(r,theta,phi )=f_i,lim,lim _{rrightarrow infty } L_{i}(r,theta,phi )=0 end{aligned} (4)In this study, the Coker and Torquato's method is adopted to obtain (L_i r,theta,phi )) for the insulating specimens, and detailed procedure is presented in Coker and Torquato (1995).
EUS-RFA resulted in well-demarcated ablation lesions in all pathology specimens and no procedure-associated adverse events.

This underlines the difficulties in standardizing clinical specimens and the microbiological procedures.
However, as a restricted number of specimens was analyzed from local communities (and procedures for specimen selection were not reported), it remained unknown if the used primer pairs and laboratory protocols would have been suitable for all species and specimens within the studied communities, a criterion which is of high importance for standardized biodiversity inventories.
A novel experimental design, using tensile tests on circular skin specimens, and an optimisation procedure were adopted for laboratory experiments to identify the material parameters of the tissue.
