A calibration method of indication error grade III standard metallic scale based on length measuring machine is proposed. The existing reformed to realize the scale. According proposed method, evaluation model measurement uncertainty established, and source analysed. expanded less than one third maximum permissible specified in verification regulation, which verifies feasibility effectiveness m...

In this study, a minimum set of low-power digital standard cells for low-leakage applications are developed and introduced into SMIC (Semiconductor Manufacturing International Corporation) 130 nm CMOS libraries, which include basic logic gates such as inverter, NAND, NOR, XOR, XNOR and flip-flop. The inverter, NAND, NOR and flip-flop standard cells based on the gate-length biasing technique are...

PURPOSE Ultrasound (US) is a useful tool for peripheral vein cannulation in patients with difficult venous access. However, few data about the survival of US-guided peripheral catheters in acute care setting exist. Some studies showed that the survival rate of standard-length catheters (SC) is poor especially in obese patients. The use of longer than normal catheters could provide a solution to...

Paramecium tetraurelia has the shortest known introns as its standard intron length. Sequenced introns vary between 20 and 33 nucleotides in length. The intron sequences were discovered in genomic sequences coding for a variety of different proteins, including phosphatases, kinases, and low-molecular weight GTP-binding proteins. All intron sequences begin with the conserved dinucleotide GT and ...

Optical tweezers have broad applications in studies of structures and processes in molecular and cellular biophysics. Use of optical tweezers for quantitative molecular-scale measurement requires careful calibration in physical units. Here we show that DNA molecules may be used as metrology standards for force and length measurements. Analysis of DNA molecules of two specific lengths allows sim...

the objective followed in the present study was to survey the relationship between 18 body trait measurements (live weight, height at wither, paunch girth, neck diameter, body length, girth around the body, width of fat tail at above, below and midpoint of fat tail, fat tail length lowers right and left sides, fat tail gap length, fat tail depth at the above, below, and midpoint, and girth arou...
