Q1 Reel master giving his imaginary answers on cabin walls of cruise
ships. This is the truth. Ship walls are built as seen in the video and are
fitted as if children play blocks. Cruise ship cabins walls are all
ferromagnetic – magnets will stick to them. They are not in themselves
magnetic, so if you want to stick something to them, it will need to be a
magnet. All cruise ships are made using steel cabin frames for the cabins.
While the stateroom doors may vary, there are no exceptions when it comes
to the cabin walls. Every cruise ship is made in the same way, with the
cabins made separately using metal walls and then slotted into place during
the construction process. The reason for this is that it makes it easy to
build the ‘exoskeleton’ of the cabins separately from the main ship build.
Having them all cut from metal to the same size and shape speeds up the
process and means assembling the ship is significantly faster. This has its
good sides and bad sides. It means phone reception can be a little sketchy
in your room, and it’ll cause interference with radio waves – not good for
anyone who hoped to use walkie talkies
<https://www.cruisemummy.co.uk/the-best-walkie-talkies-for-cruise-ships/> from
within their cabin. But it does mean that you can stick magnets to your
cabin walls. I always take magnetic hooks on a cruise. This gives us lots
of extra space to hang coats, bags and other bits and pieces. (WATCH THE
VIDEO BELOW). https://youtu.be/y7i0pf1UBEc
Q2 Another master bolt: It reduces snapping Great!! Even thin wire
will not snap. The resistance of connecting wires should be almost
negligible. For these thick wires are used. since a thicker wire has a
small resistance and the wires are made of copper because the resistivity
of copper is low. The larger the cross-section of a wire, the less its
resistance. Also, the larger the cross-section, the greater the amount of
current (amperage) the wire can safely carry before overheating. A wire
with a smaller gauge (larger diameter) can carry more power than one with a
larger gauge. The purpose of any wire is to transmit power at a certain
distance with the least amount of resistance. The more power and equipment
you have, the larger the wire size needs to be. If too small wire size is
used, the wire would deteriorate and its Insulation would melt because of
the large amount of current flowing through it compared to rated capacity
of the cable. The smaller the wire diameter, the higher the resistance
there will be to the flow of energy. When you have high resistance, you
generate heat that can turn into a fire hazard. Proper wire size is
important for any electrical wire installation. The wire size represents
the diameter of the wire conductor. The wire gauge refers to the
current-carrying capacity of the wire or how much amperage the wire can
withstand safely. When selecting the correct size of the wire, consider the
wire area, the wire power, and what the wire would be used for. Proper
sizing of cabling is most important for the reliability, consistency and
safety of the system. The oversize cable is a waste of money and under-size
can cause short circuit or fire. Also, you have to consider the type of
cable (single-core, multi-core) whatever is suitable for your application.
Last but not the least is the way you lay the cable. You must take into
consideration that the cable is in trunking or on cable trays.
Q3 another intimidation by the reel master on B 12. Vitamin B12 is a
water-soluble vitamin that is naturally present in some foods, added to
others, and available as a dietary supplement and a prescription
medication. Because vitamin B12 contains the mineral cobalt, compounds with
vitamin B12 activity are collectively called “cobalamins”]. Methyl
cobalamin and 5-deoxyadenosylcobalamin are the metabolically active forms
of vitamin B12. However, two others forms, hydroxocobalamin and
cyanocobalamin, become biologically active after they are converted to
methyl cobalamin or 5-deoxyadenosylcobalamin]. Vitamin B12 is required for
the development, myelination, and function of the central nervous system;
healthy red blood cell formation; and DNA synthesis]. Vitamin B12 functions
as a cofactor for two enzymes, methionine synthase and L-methylmalonyl-CoA
mutase. Methionine synthase catalyzes the conversion of homocysteine to the
essential amino acid methionine. Methionine is required for the formation
of S-adenosylmethionine, a universal methyl donor for almost 100 different
substrates, including DNA, RNA, proteins, and lipids. L-methylmalonyl-CoA
mutase converts L-methylmalonyl-CoA to succinyl-CoA in the metabolism of
propionate, a short-chain fatty acid.
Vitamin B12 is naturally present in foods of animal origin,
including fish, meat, poultry, eggs, and dairy products [5
<https://ods.od.nih.gov/factsheets/VitaminB12-HealthProfessional/#en5>]. In
addition, fortified breakfast cereals and fortified nutritional yeasts are
readily available sources of vitamin B12 that have high bioavailability.
The average vitamin B12 level in the breast milk of women with
vitamin B12 intakes above the RDA is 0.44 mcg/L. The U.S. Food and Drug
Administration specifies that infant formulas sold in the United States
must provide at least 0.15 mcg vitamin B12 per 100 kcal.
No evidence indicates that absorption rates of vitamin B12 in
supplements vary by form of the vitamin. These rates are about 50% at doses
(less than 1–2 mcg) that do not exceed the cobalamin-binding capacity of
intrinsic factor and are substantially lower at doses well above 1–2 mcg.
For example, absorption is only about 2% at doses of 500 mcg and 1.3% at
doses of 1,000 mcg. THAT MEANS EVEN IF ONE TAKES AN EXTRA TABLET,
ABSORPTION IS VERY LOW AND THE REMAINS ARE EJECTED OUT. IF SOMETHING WERE
TO HAPPEN, SAY E VEN AT 25%, ONE MUST TAKE 12 TO 24 TABLETS A DAY WHICH IS
FUNNIER. ONLY OLD PEOPLE, ANEMIC, LIVER SURGERY PEOPLE, VEGETARIANS ARE
SUPPOSED TO RUN INTO DEFICIENCY.
ADVERSE FACOR: Some observational evidence also shows an
association between supplements containing vitamin B12 and a higher risk of
certain types of cancer. For example, an assessment of 77,118 participants
aged 50 to 76 years in the Vitamins and Lifestyle cohort study found that
use of at least 55 mcg/day supplemental vitamin B12 for an average of 10
years was associated with a 40% higher risk of lung cancer in men However,
the study found no association between supplemental vitamin B12 use and
cancer risk in women. OTHER THAN THIS AND EVEN IN THIS, IT IS NOT CERTAIN
THAT IT WILL BUT ONLY “MAY”. (National health analysis and facts check)
