Stronger version of the big O notation, basically means that ratio goes to zero. In big O notation, the ratio does not need to go to zero.
E.g.:
- K does not tend to zero
Very good metabolism database.
Some things that they have of interest which may not be on NCBI:
Hits a free login wall after a few IP hits. And just a very normal casually browsing number of hits. What is this bullshit?
Their YouTube: www.youtube.com/channel/UCR9QDQ_9_N4isZV_YRQg9tA has some good tutorials.
In some contexts, we want to observe what happens for a given fixed magnetic field strength on a specific plate (thus and are also fixed).
In those cases, it can be useful to talk about the "Hall resistance" defined as:So note that it is not a "regular resistance", it just has the same dimensions, and is more usefully understood as a proportionality constant for the voltage given an input current:
This notion can be useful because everything else being equal, if we increase the current , then also increases proportionally, making this a way to talk about the voltage in a current independent manner.
And this is particularly the case for the quantum Hall effect, where is constant for wide ranges of applied magnetic field and TODO presumably the height can be made to a single molecular layer with chemical vapor deposition of the like, and if therefore fixed.
These are commands that e.g. the Bitcoin CLI client can make to the server.
The commands can be listed with:and full help with:
bitcoin-core.cli helpbitcoin-core.cli help getrawtransactionFor example. to run the Bitcoin and then on another shell:
getrawtransaction command, first in one shell we start bitcoind:bitcoin-core.daemonbitcoin-core.cli getrawtransaction 75b431e0a8c4617ca8adefe593ba66aa30907742b6dc8772761bfe7edabd74b4 trueIt runs along quiet roads, rather than a mixture of roads and tracks like the National Cycle Network, making it more appropriate for road bikes.
TODO interactive online app? Ahh, those charities that try to make money by individual transactions... when they die, nothing will be left of all their work.
Edit: noticed that it is on by default on OpenStreetMaps web UI under the "Cycle Map" layer marked at "NB".
Ciro Santilli's birthplace!
Ciro Santilli lived in Santos from about the year 1998 to 2007, with a 10 month hiatus in Coventry, UK, until he went to the University of São Paulo.
Santos is the nearest beach city to São Paulo City, and for this reason:
- the largest port of Latin America in 2018, through which large chunks of the precious coffee export exited Brazil in the 19th century. There is a Coffee museum in Santos.This importance is also linked to the fact that Santos is one of the oldest european cities in Brazil, being founded in 1546. From this you can infer that it was a good port. One reason for this is obvious if you look at the map of the city: the neighbouring towns of Praia Grande and Guarujá form a large protected bay where ships may safely dock.
- a popular local tourist destination that gets crowded on hot weekends, with the beach line being fully built with tall buildings from the 60's, many of which became incredibly bent due to the inadequate technology used on such soft soil
Ciro idolizes Santos as the perfect location to live nature-wise due to its amazing wide sandy beach, in which Ciro spent endless hours walking on the sand and on the largest beachfront garden in the world (archive), meditating, and playing some soccer after school was over. Santos is also the city where Pelé first played professionally.
Ciro has visited Santos several times after leaving Brazil. Doing this gives him a weird feeling of having a separate life, in which time passes 2 weeks every few years. Of course, as your family grows, it gets harder and harder to go back home, and your family members might want to just go travel to more interesting places than just stay at your wonderful beach which you love in part due to nostalgia.
Ciro is also fond of the concept of the small public buildings near the beach garden (postos de praia), which serve different cultural activities: library, comic book store, art cinema, surf school. It is such a shame that the library and comic book ones are in such bad shape as of 2020, old books and poor people who go there to sleep a bit in the barely working air conditioning. Ciro fantasizes how those could instead be cultural hubs for the gathering of the brightest artists, and scientists, of town. Maybe they are just too small. Maybe it is not within the realm of possibility of public service. Maybe, we should focus instead in the poorer regions, far form the beach. But the dream remains.
Santos only has one natural defect: mosquitoes. By the sea it is fine because the wind is strong, and they don't like salt water. But anywhere else, you will be eaten alive, and maybe get dengue, Ciro got it once. Gene drive, please.

Canal 5 on the beach by VicTrindade (2017)
Source. This is one of Santos 7 old canals, which are still in use and serve to reduce floodings in the city, which are caused by the strong tropical rains that fall on the city. This is particularly important to keep the mosquito population under some control. All canals were built in the first third of the 20th century, except canal 7 which is from 1968[ref]. The canals have normally very shallow water when it is not raining, and since it is rain water they are basically clean. There are other canals which are/were used for sewage, but then are not open air. The canals now serve as handy reference points and practical avenues in town, as well as being surrounded with nice trees that provide shade and drop small inedible purple fruit that will stain your car for all eternity. They do scar the beach line a bit it must be said, but it's part of the charm of the city, and they serve as good reference points for runners.
