black hole butt
Roger Sharp added another item to his summary of feedback about black holes that can be found on surface maps of our planet (October 7).visitors to Nelson’s Mai Tai Esplanade ReserveNew Zealanders may feel relieved after entering a Blackhole public toilet.
Feedback points out that installing a toilet in an astrophysical black hole would eliminate the need for some expensive parts of modern waste treatment facilities, particularly sewage piping systems and septic tanks.
insert a needle into the patient
How far is it okay to insert a needle a little too deeply into someone’s abdomen? 365 surgeons from 58 European countries gave their opinion on this topic. Their thoughts, desires, and perhaps even dreams are distilled into a study called “.Relevance of Veres needle overshoot reductionBy researchers from the Netherlands and Malta.
These are the needles used to inflate the patient before performing the internal looking and subsequent cutting and manipulation tasks that are the highlight of most laparoscopic surgeries. A special type of needle called a Veres needle has long been the standard device for puncturing and injecting air into people who enter a shop for repairs. This performs much the same function as a simple type of needle used to inflate a soccer ball.
This study investigates the desire and need for a new and better Veress needle design.
The researchers said that surgeons “felt it was important to have a firm grip on the needle shaft, as most respondents held the needle rather than the grip.” The reason is that some surgeons try to stabilize their hands by touching the abdominal wall with their fingers during insertion, and the grip is too far from the abdominal wall. The data also shows that the maximum overshoot should be limited to 0 to 10 mm. ”
Almost every professional activity has a specific tolerance for error. Publication of this paper will make the public more aware of professionals’ general tolerance for overinsertion of injection needles in laparoscopic surgery patients.
goaf gangue
Unfamiliar scientific terminology can be fun, especially when the words are mined from depths that are unfamiliar to most people.
The same goes for gangue and goaf. He came across the feedback while reading a report by Zhanshan Shi of China’s Liaoning University of Technology and colleagues.Simulation test study on filling flow law of gangue slurry in goaf”.
Goaf is the waste that accumulates during mining. Gangue is a seemingly worthless portion of ore extracted from a mine. Goaf necessarily has gangue.
There are also mysteries. The report states that “there is little research on flow rules for gangue slurries in the Goahu sedimentary rock mass.”
This report is a reminder that there is always something yet to be unearthed, even if it is just information.
wooden board
In the vast forest of nominative determinism of people whose names are hilarious and almost eerily related to work, a few trees, namely the names of some people, are particularly suited to the purpose. One is Marlin E. Plank, who served as a forest products research technician at his Pacific Northwest Research Station in Portland, Oregon. He spent much of his professional life estimating how much commercially useful wood could be obtained from certain types of trees.
Stewart Harrison told Feedback of his joy upon discovering Planck’s 1982 paper.Harvesting wood from ponderosa pines in western Montana”.
A trip through the library found more plankitudes, including a plank on a log.Estimating the volume of small-diameter logs of ponderosa pine and lodgepole pine”.
Planck’s most sophisticated log paper may be the one he co-authored with Floyd Johnson in 1975 called .Empirical log rules for Douglas fir in western Oregon and western Washington”. This describes a better way, a low-key and practical way to estimate how much wood you will get if a tree is plank-harvested.
Plank and Johnson said: “The traditional procedure for estimating timber aggregates is based on theoretical log rules, defect deductions, and overrun factors. This procedure is indirect, subjective, and complex. It is also clearly inaccurate. Theory A better procedure is described that is based on actual wood recovery rather than the wood recovery above.”
Planck passed away in 2014. The Planck memorial website says:To plant a tree in your memory, visit the Sympathy Store.”.
