Never seen these until today. I think they are called currach oars. Massive. What is the reason are made such way ? Appear to be poorly efficient.

Thanks, thought of that rule, but being text that can be long-string-entered in the search box to yield the source, did not. Sites are : 3-d at ----> https://www.acq.osd.mil/ncbdp/narp/Radiation_Data/Radiation_Detection_and_Measurement.htm Page 2 at ----> https://med.uth.edu/radiology/files/2016/03/Lab7_Thyroid_Uptake.pdf

Thanks. I understand then, that lead used as a gamma shield works by absorbing much more than reflecting the radiation. OK. 'Funneling' or 'paraboling' would take gold surfaced mirrors to concentrate reflections. From a DoD site : "... a 60- keV gamma ray has a typical range of a 100 meters in air and might penetrate a centimeter of aluminum."... And by total coincidence, found a lead 'funnel' being used :

Thanks. I will take that as "The amount of americium in a typical new smoke detector is 0.29 microgram with an activity of 1 microcurie = 37 kilobequerels (1.0 μCi = 37 kBq)." So, is the Am gamma portion too weak to be detected at distance ? ----> https://www.sciencedaily.com/releases/2018/04/180425120132.htm Can the gamma radiation be 'funneled' towards a detector ? -Say a lead funnel- Does gamma rays bounce or are absorbed by Pb ?

Hi. Smoke detectors containing Americium... Can some gamma sensor discern if a house has one installed from 50 metres away ? Can instead, a single Am pellet extracted from such smoke detector be detected from a distance ?

A beacon is usually a light source, in a rotating enclosure blocking emission in one direction and a window on another direction. Think of a police vehicle beacon. What other 'emissions' can be/are used instead of light ? As sound as Leslie effect, radiowaves, magnetism ? gamma rays ? that can be detected at -say 50- metres away ?

Thanks, Sensei. Good explanation, but does not work for me, at least yet. Cannot get it in french/for France, nor the 'Parametres de recherche' show. Perhaps my default search engine would have to be Google for that. Will explore further. Never had to do any private window before.

Sometimes I search using Google when after things within foreign countries. Like google.it; Google.es; Google.fr; Google.uk There was a selection for results only for that country, now there is only a selection of language (if that much). Do you see the same ? You Google users and experts, do you know how to select results only from the country searched ? Example: if you know french, look for antiques boutiques in Montmartre ----> https://www.google.fr most results are in English. It used to be all results from France only, in french, selectable. Is this the result of tracking, location and personal data collection ? Edit: Checking my own link above; minutes ago was in french. Now is in English.

Welcome. The antenna would be called a microphone. Perhaps metallized PVDF film, low pass filtered amplification. Held to the rim of a drum or alike ring, and in a very quiet location. A piezofilm speaker could be used as microphone ----> https://duckduckgo.com/?q=pvdf+film+speaker&t=canonical&iar=images&iax=images&ia=images

Hi. A SHAME : And it is not the first time I see this. They are capturing babies, well under reproduction age, leaving no hope to future populations . With a third of contents being cheap oil. Remember when there were two to three tightly packed. Like 15 now. [Product of Poland]

OK, Brett. Those are the would be. What are the is ? - Define perpetual. - How many have you sold ?

Small engines like Briggs Stratton may have a governing linkage for steady rpm on certain applications. Seen several implementation ways, but my mower has a weak spring paralleled to the rod, both attach to the same points. How do they work? Makes not much sense seeing such configuration, but there has to be a detail/reason am missing. Is it related to avoid speed 'hunting' or steadyness ? [The choke has nothing to do with the subject] The rod often runs inside spring. The anchoring is slightly different here at the right side lever, attaching to apart holes, which may show more logic : -Images borrowed from the web-

For the finances side, You have to compete with the $1 radio that includes earphones and light. Price to public=$1 The store profit is around $0.50 The manufacturer cost in design, parts, assembly labor is around $0.25 to make a $0.25 profit. There is also shipping, marketing, packaging costs. ----> https://frrl.wordpress.com/2009/02/28/a-fm-radio-for-one-dollar-how-is-this-possible/ If you want to earn $100 daily selling radios, at a $0.25 profit each, you have to sell 400 daily.

Still have to find out what chemicals are dissolved, what temperature has, and zero sunlight...

I have to toss a couple of things to the table... Blood in contact with air promotes coagulation. That cannot be good. Air embolia is neither a good thing... ----> https://www.nhs.uk/conditions/air-embolism/

Thanks, StringJunky. Am referring to bubbles traveling by the hose into the body. Perhaps there is different kinds of bags or equipment. With the dripping chamber or not.

Visiting patients, seen several times that nurses pay no attention to bubbles flowing into intravenous fluid hose. Verbally spanked several occasions the nurses in charge, like they do not pay attention nor care about this. How dangerous is it ? I do not know if is because some fitting is not tight, or else. What happens with bubbles flowing into narrowing arteries ?

Can a higher blood pressure fight better a forming arterial clot pushing more blood trough the narrowing to keep tissues downstream alive ? Or, can 'healthy' low blood pressure contribute to death of downstream tissues because does not push enough blood trough a forming clot ?

Solution to overpopulation... Compensation has to be the key. Allow benefits / less taxation / incentives / health care / access and preferences to housing programs, employment, pay raises... to families with less children. Instead of punishing families with too many children.

Fishing boats have an allowed quota for a certain tonnes of captures each season on certain areas/countries. Would it be feasible, to allow additional tonneage to fishing vessels that bring to shore the sea of plastic ? For a ton of plastic removed, an extra ton of fish allowed to capture. Just imagine these nets doing cleanup when the vessels are done for the season. It has to help, hasn't ? The planet wins, the fishermen win, rewarded right away or for the next season with more quota than their competitors. And a cleaner sea has at some point to benefit the fishermen too, right ? How to implement details ? Acceptance expectations ? Whom to propose or am aiming too high ?

Somehow, never considered morphology on a snail being right or left, irrelevant, not to pay attention. Thought there were both kinds of it, randomly. A publication says the lefty species is a rarity. "The lefty is the right one" :

OK, got it... I think 1/3 of oxygen means also 1/3 of nitrogen. Compressing brings up the density of both to a tolerable level as in ~3000 ft. My misconception may had been believing that only oxygen was less dense at altitude, as if it was a stratified column of air from hearing "There is less oxygen at high altitude" Well, yes, but there is less nitrogen too, actually being "There is less air at high altitude" -There is less O2 because the whole air is less dense.- That is why compressing takes care of it.

3000 ft is the guessed altitude or equivalent pressure I read on my altimetre as a passenger above the Andes on a pressurized cabin. Read again. Also brought to guesstimate as cabin pressure at 30,000+ft by Janus. Also destination of flight being Quito, cabin pressure had to be gradually brought to same as landing site.
