After a grueling 10 weeks at
sea, the Mayflower, with 102 passengers and a crew of about 30, reached
America, dropping anchor near the tip of Cape Cod, Massachusetts, on November
21 [O.S. November 11], 1620.Arriving in
November, they had to survive unprepared through a harsh winter.
In
the stock casinos, yet more nervousness about the surging coronavirus
infections in the USA and their likely effect on the US economy.
Will
next week’s Thanksgiving Day holiday generate yet another surge in infections
right before Christmas?
No
one knows off course, but if many Americans travel to the usual large family
gatherings there’s a high probability of a spike in new infections starting
about the second week of December and running out to the New Year.
What
that would do to the already slowing US economy is likely to slow it even
further. But would it have any effect in the stock casinos?

(Reuters) - The U.S. Centers for Disease
Control and Prevention (CDC) on Friday reported 11,650,817 cases of the novel
coronavirus, an increase of 185,095 cases from its previous count, and said
that the number of deaths had risen by 2,045 to 251,715.

LONDON (Reuters) - People who’ve had COVID-19 are highly
unlikely to contract it again for at least six months after their first
infection, according to a British study of healthcare workers on the frontline
of the fight against the coronavirus pandemic.
The findings
should offer some reassurance for the more than 51 million people worldwide who
have been infected with the pandemic disease, researchers at the University of
Oxford said.
“This is
really good news, because we can be confident that, at least in the short term,
most people who get COVID-19 won’t get it again,” said David Eyre, a professor
at Oxford’s Nuffield Department of Population Health, who co-led the study.
Isolated
cases of re-infection with COVID-19, the disease caused by the SARS-CoV-2
virus, had raised concerns that immunity might be short-lived and that
recovered patients may swiftly fall sick again.
But the
results of this study, carried out in a cohort of UK healthcare workers - who
are among those at highest risk of contracting COVID-19 - suggest cases of
reinfection are likely to remain extremely rare.
“Being
infected with COVID-19 does offer protection against re-infection for most
people for at least six months,” Eyre said. “We found no new symptomatic
infections in any of the participants who had tested positive for antibodies.”
The study,
part of a major staff testing programme, covered a 30-week period between April
and November 2020. Its results have not peer-reviewed by other scientists but
were published before review on the MedRxiv website.
During the
study, 89 of 11,052 staff without antibodies developed a new infection with
symptoms, while none of the 1,246 staff with antibodies developed a symptomatic
infection.
Staff with
antibodies were also less likely to test positive for COVID-19 without
symptoms, the researchers said, with 76 without antibodies testing positive,
compared to only three with antibodies. Those three were all well and did not
develop COVID-19 symptoms, they added.
MMR vaccine may protect
against severe illness from COVID-19, study finds
Nov. 20, 2020 / 4:59 PM
Nov. 20 (UPI) -- The measles, mumps and rubella vaccine appears to offer at least
some protection against COVID-19, possibly preventing severe illness from the
disease, a study published Friday by the online journal mBio
found.
Among 41 people born in the United States who received the
shot -- known as the MMR vaccine -- eight had immunity against the new
coronavirus or had no symptoms after becoming infected, the researchers said.
This apparent immunity against severe COVID-19 may have
been because of their high levels of antibodies -- or immune cells that fight
off infection -- against the mumps, they said.
Seventeen people who received the MMR vaccine but had lower
mumps antibody levels developed only mild COVID-19 symptoms, while those with
the fewest mumps antibodies after vaccination suffered moderate illness or
needed to be hospitalized for treatment.
"This
adds to other associations demonstrating that the MMR vaccine may be protective
against COVID-19," study co-author Dr. Jeffrey E. Gold said in a
statement.
"It
also may explain why children have a much lower COVID-19 case rate than adults,
as well as a much lower death rate," said Gold, who is president of
Watkinsville, Georgia-based World Organization, which led the research.
More than
95% of all children in the United States receive their first MMR vaccination at
12 to 15 months old and a second shot between the ages of 4 and 6 years,
according to the Centers for Disease Control and Prevention, which strongly recommends
the shot.
Next, some very useful vaccine

informative update from Stanford Hospital in California.
The Arctic winter sea-ice expansion and
northern hemisphere snow cover. From around mid-October, the northern
hemisphere snow cover usually rapidly expands, while the Arctic ice gradually
expands back towards its winter maximum.
Over simplified, a rapid expansion of
both, especially if early, can be a sign of a harsher than normal arriving
northern hemisphere winter. Perhaps more so in 2020-2021 as we’re in the low of
the ending sunspot cycle, which possibly also influenced this year’s record
Atlantic hurricane season.
Adding to this year’s winter concerns,
a developing La Nina weather pattern in the Pacific. While the La Nina effect
on the winter weather of western Europe is weaker than that of an El Nino
pattern, which tends to make for a milder winter, a La Nina pattern tends to
make for a colder winter.
Northern Eur-Asia turned snowy fast in
mid-October.The Arctic sea ice
expansion was slow, and from a very low level at the end of September, but with
the vastly expanded snow cover, sea ice formation sped up.
With the Laptev sea ice virtually back
to normal, at the end of the third week of November I’m starting to think that
it will likely be a normal to slightly warmer winter ahead for western Europe.
The failure of the Kara Sea ice to
return to normal, would lead me to bet on a warmer western European winter ahead.
With events happening fast in the development of solar power and
graphene, I’ve added this section. Updates as they get reported. Is converting

Getting single-crystal diamond
ready for electronics
Date: November 10, 2020
Source: Osaka University
Summary: Researchers polished
single-crystal diamond to near-atomic smoothness without damaging it. This will
improve the performance and sustainability of future electronics.
Silicon has
been the workhorse of electronics for decades because it is a common element,
is easy to process, and has useful electronic properties. A limitation of
silicon is that high temperatures damage it, which limits the operating speed
of silicon-based electronics. Single-crystal diamond is a possible alternative
to silicon. Researchers recently fabricated a single-crystal diamond wafer, but
common methods of polishing the surface -- a requirement for use in electronics
-- are a combination of slow and damaging.
In a study
recently published in Scientific Reports, researchers from Osaka
University and collaborating partners polished a single-crystal diamond wafer
to be nearly atomically smooth. This procedure will be useful for helping
diamond replace at least some of the silicon components of electronic devices.
Diamond is
the hardest known substance and essentially does not react with chemicals.
Polishing it with a similarly hard tool damages the surface and conventional
polishing chemistry is slow. In this study, the researchers in essence first
modified the quartz glass surface and then polished diamond with modified
quartz glass tools.
"Plasma-assisted
polishing is an ideal technique for single-crystal diamond," explains lead
author Nian Liu. "The plasma activates the carbon atoms on the diamond
surface without destroying the crystal structure, which lets a quartz glass
plate gently smooth away surface irregularities."
The
single-crystal diamond, before polishing, had many step-like features and was wavy
overall, with an average root mean square roughness of 0.66 micrometers. After
polishing, the topographical defects were gone, and the surface roughness was
far less: 0.4 nanometers.
"Polishing
decreased the surface roughness to near-atomic smoothness," says senior
author Kazuya Yamamura. "There were no scratches on the surface, as seen
in scaife mechanical smoothing approaches."
Furthermore,
the researchers confirmed that the polished surface was unaltered chemically.
For example, they detected no graphite -- therefore, no damaged carbon. The
only detected impurity was a very small amount of nitrogen from the original
wafer preparation.
"Using
Raman spectroscopy, the full width at half maximum of the diamond lines in the
wafer were the same, and the peak positions were almost identical," says
Liu. "Other polishing techniques show clear deviations from pure
diamond."
With this
research development, high-performance power devices and heat sinks based on
single-crystal diamond are now attainable. Such technologies will dramatically
lower the power use and carbon input, and improve the performance, of future
electronic devices.

some place called the Hinterlands, and everything they do is wrong. They buy

of charting the activity of Mr. J. and his poor brother. If I knew them I would
give them room and board and consult them…. I would push the pheasant and
champagne through the little hatch of his cell and ask Mr. J. what he was going
to do that morning, and if he said, “buy,” I would know to sell, and so on.
