The Laparoscopic Surgeon's Posture
Published in Marilyn Sue Bogner, Misadventures in Health Care, 2003
Handle Shape of the Surgical Instruments. Although the length of the shaft is fairly consistent across laparoscopic surgical instruments, various types of handles are available. The most common are ring handles similar to those on scissors and shank handles that are commonly used on pruning shears. These handles are available in angled or axial orientation in relation to the shaft of the instrument. Either handle can be used with one hand to operate the two functions of the instrument: opening and closing the effector, and rotating the effector. Additional functions such as angling the shaft can only be performed with two hands, which necessitates interrupting the procedure while the surgeon gets off the second instrument.
The Grading and Quality of Dried Cocoa Beans
Published in Hii Ching Lik, Borém Flávio Meira, Drying and Roasting of Cocoa and Coffee, 2019
Apart from the visual assessment made during the cut test, aroma is also best assessed immediately after cutting. The Magra bean cutter has the advantage of allowing you to immediately smell the aroma from the beans by cutting 50 beans at once and then assessing the aroma by smelling the rows of cut beans on the Magra cutting bed. Aroma assessment is done on individual beans if cut using a knife or anvil type pruning shears. Defects such as smoke and oily taints and even putrid or hammy notes from over-fermentation can be detected at this stage, and it may be a good reason to reject or discontinue further evaluations after these defects are identified.
Handtools
Published in Stephan Konz, Steven Johnson, Work Design, 2018
Paivenen et al. (2000) gave ergonomic design criteria for plier and shear-like tools. Design the tools to be used by either or both hands and to use either forward or reverse grips; the handles should be at least 125 mm long (to allow use of gloves) and not have grooves. Shears should have a large opening angle as this permits the material to be inserted deeper into the shears and thus reduces force requirements. Pruning shears used in fruit trees should have a wrist wrap to reduce risk of dropping.

Measurement of biomass of S. babylonica as follows: at termination of the experiment, the roots, stems, and leaves of S. babylonica were washed with deionized water, then wiped dry with absorbent paper, cut off with pruning shears and packed into envelopes respectively. Finally, drying in the oven for 24 hours, the weight of S. babylonica was weighed. The changes of its biomass under the stress of 2, 4-DNP were analyzed.
