Clinical trial endpoints can be classified as primary or secondary. The primary endpoint is the most important outcome and is used to assess the primary objective of a trial. Primary endpoints measure outcomes that will answer the primary or most important question being asked by a trial, such as whether a new treatment is better at preventing disease-related death than the standard therapy 33.

In a size reduction crushing operation, feed size is 300 to 1500 mm while the product size is 100 to 300 mm. This is a case of the __________ crushing.
The primary crusher (e.g. jaw crusher) breaks the reinforcing steel from the concrete and reduces the concrete rubble to a maximum size of 75 mm (3 in) to 100 mm (4 in). As the material is conveyed to the secondary crusher steel is typically removed by an electromagnetic separator. Secondary crushing further breaks down the RCM which is then.
Requires a fine CSS on the primary crusher and operates at a coarse CSS on the secondary crusher which results in more intermediate critical size material. High crusher wear as fines are not removed. Suitable for primary mills with recycle crushers, for a moderate
· Types of crushers. Crushers are classified into three types based upon the stage of crushing they accomplish. These are (i) primary crusher, (ii) secondary crusher, and (iii) tertiary crusher. The primary crusher receives material directly from run of mine (ROM) after blasting and produces the first reduction in size.

· Supplementary Alignment: A chimeric reads but not a representative reads. Primary Alignment and Secondary Alignment: A read may map ambiguously to multiple locations, e.g. due to repeats. Only one of the multiple read alignments is considered primary, and this decision may be arbitrary. All other alignments have the secondary alignment flag. 5.
· crusher. Primary Crusher — The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary or tertiary crushers. Product — Output from the crusher. Reduction Ratio — The ratio of the top size of
further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG mill feed size (Kosick and Bennett, 2001). The SPI values varied from 13.5 to 107 minutes with an average of 53 minutes. This variability, although
· This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.

· Primary research is a research approach that involves gathering data directly while secondary research is a research approach that involves relying on already existing data when carrying out a systematic investigation. This means that in primary research, the researcher is directly involved in the data collection and categorization process.
Fifty-nine patients with primary and 15 patients with secondary cysts underwent laminotomies with complete or partial cyst resection and duraplasty. Mean follow-up was 57 ± 52 months. In the first postoperative year, profound improvements for primary cysts were noted, in contrast to marginal changes for secondary cysts.
