Technology / Re: Does regenerative braking have a hazardous complication?
« on: 02/05/2024 11:49:41 »That indeed is a possible unintended consequence- whether it has been researched, I do not know.
I think I do.
As they have been mandatory for about 100 years it would be difficult to disentangle this hypothesis from the statistics of increased traffic density, increased speeds, mandatory speed limits, improved tyre treads, and brakes that actually work.
That's why I asked.
I recently spoke to a guy on Twitter who designed side-impact protection for cars, so I asked him if there was any evidence that SIP had saved any lives. He didn't have an answer, and the more I pressed him the more he squirmed.
People just assume that if something's intended to save lives, then it does save lives. Drugs would probably be an exception, generally they don't get a a licence without some evidence that they work first.
My car (fully EV, Polestar 2) can be set to one pedal or two pedal driving; the former makes maximum use of regenerative breaking and I barely need to use the brakes. It definitely puts the brake lights on in this mode.
I've never driven an electric car, but I don't like the idea of having braking shared between two pedals rather than separate pedals for brake and accelerator. I can foresee dangerous dithering: if an emergency starts to develop I can imagine being undecided whether staying on one pedal will provide enough brake force or whether I need to move to the other. That's not going to be conducive to fast reaction time, and if you continue jumping for the brake automatically like in an ICE car it risks creating a pile up with unnecessarily sharp braking. Far better to put your foot on the brake, and then just modulate the pressure according to how the situation develops.
I think I'd want a switch for a "simulate ICE" mode, in which the regenerative braking simulates engine overrun unless I swap to the brake pedal.
Another note: How efficient is regenerative braking. How much energy is lost regenerating and then re-accelerating? How can an EV get decent range if it cannot just coast and allow a minor variation in speed?
I suppose the answer would have to be that you can still coast by adjusting your foot position accurately/carefully enough, but I doubt people will, and the idea doesn't appeal to me much.

« on: 24/04/2024 18:24:08 »the pedal is interpreted as an absolute speed suggestion and not a throttle (power suggestion). This interpretation lets you maintain more constant speed over small hills without so much reaction required at the pedal.Cruise controls maintain a constant speed as the gradient changes, unlike drivers' right feet, which leaves the strange feeling that you're accelerating uphill and decelerating downhill. Other drivers around you also make the same mistake.

More averaging needed.
I was getting little more than 4% variation if I exclude the one year where my driving was materially different:

« on: 22/03/2024 11:51:40 »Also, is less confusing.If we're on the subject of needlessly confusing systems, I'd like to know what bright spark thought it was a good idea to call a longitudinal measurement latitude and a lateral measurement longitude. If you apply the same logic to a tape measure my garden path is a hundred feet wide and three feet long.
And whilst we're on the subject of minutes & seconds, I think it's a crying shame that luddites defeated the decimal clock, too.

Just Chat! / Re: How Much Dish Detergent To Use.
« on: 16/03/2024 12:33:45 »add more when the bubbles don't formI add more when the water starts looking tired, but I find it takes a bit more than that if I want a oily grill pan to feel squeaky clean rather than looking clean but with a slithery greasy feel.
for really good results, to save the planet, and to maximise the utility of your one life, use a dishwasherMy mother used dishwashers at work, and reckoned that by the time you've pre-washed the dirty stuff before you put it in, and washed the stuff off that the dishwasher missed afterwards you might just as well do the job yourself in the first place. Being as that sounds like having a dog and barking yourself I've never been tempted to try one. (That and the fact that there isn't really room for one.)
really active detergent would seriously damage your skinDo you know what Bissel put in their carpet cleaner? It stripped all the natural oils out of my skin when I used it to clean the three piece suite, and since then my hands have become permanently intolerant of just about everything.

It intrigues me that something as seemingly mundane as 'activated charcoal' appears to be a universal barrier against all poisons. I would have expected a fresh race to find a new high-tech protection against each new poison.

Technology / Re: How is electrolysis of water done safely?
« on: 29/02/2024 01:11:19 »
I recall a TV prog (might have been Open Uni, can't remember) about an industrial accident at a dockyard. They were working on a ship in dry dock using pneumatic power tools and couldn't connect them because the hose connectors were the wrong type. After changing the connectors they got on with the job, and noticed that their fags were burning unusually fast, but thought nothing of it. It wasn't until after the explosion that they found out that the reason the hoses wouldn't fit the unions was that they were connecting them to the oxygen supply instead of the compressed air.

Physiology & Medicine / Re: Can General Anaesthetics Cause Diabetes?
« on: 18/02/2024 17:27:49 »You have an absolute right under GDPR to see your medical records.No you don't.
GDPR devolves health record access to the pre-existing Access to Health Records Act, read it and you'll see that the latest amendment to take account of GDPR is dated 25.5.18, the day that GDPR came into force.
If you read the legislation you will find that Section 5 states that records can be withheld if releasing them would cause 'serious harm' to anyone (including a doctor or a third party, and not just the patient), and that the arbiters of what is harmful are the doctors (whose reason may or may not be legitimate). Neither the patient nor their solicitor are allowed to know this reason, so even if you exercise your right to take it to court, you have no means of arguing your case. Never mind that most patients won't have thousands to spend on legal fees each time they need to access their records.
This was also confirmed to me by a lawyer at Mishcon de Reya who specialises in medical records.
Finally, the NHS don't need to use any of this anyway, all they have to do is deny that the records exist, and then you can't complain that you haven't been given them. The same applies to correspondence, if they reply you have something to challenge, and evidence to show others, much better to just ignore it, then you have no proof they didn't answer.

Physiology & Medicine / Re: Can General Anaesthetics Cause Diabetes?
« on: 16/02/2024 16:25:29 »I would suggest you do some doctor shoppingIn 2016 I had a report on a series of ECGs from a very helpful professor in London which proved that the NHS were lying, without any shopping around at all, so when I was facing an unnecessary anaesthetic for a cystoscopy that I didn't need I tried the same again. This time I went all round the private sector and just got told to go to the NHS or that I needed a referral from the NHS. They've been warned off for pulling the rug out from under the NHS's feet.
As regards your problems with the NHS, I can't comment as I live in Ireland.Most countries have the same issues. It isn't really about medics even, as the Post Office scandal shows, it's just human nature. If you'd been there yourself you'd know.
involve your Member of ParliamentI assume you're unaware that MPs have no power over the PHSO then? The ombudsman is ostensibly there to police the MPs, so you can't have the PHSO and MPs each policing the other. The PACAC Committee supposedly oversees the PHSO, but they don't actually do anything beyond a token meeting once a year. When I wrote to my MP I got no reply, and the stock line from the PACAC Chair is that they don't get involved in individual cases. I've been going at this for eight years, just how much is there that you think I (and all the others in a similar position) haven't already done in that time? I know someone who has been going at this for over 20 years, spent north of ?100k on legal fees, had coverage on national TV, and still got nowhere. Have you ever heard the term 'duty of candour'? That was his doing, but it still hasn't got any of us anywhere. Like I said, even Scotland Yard were thwarted. Nothing came of the Gosport Inquiry, even though Nurse Spilka testified that they were euthanising patients just because they were regarded as "difficult". I've lost count of the times I've seen that in my records. I've been told I'm "notoriously difficult" to my face.
The case of the missing MDT record suggests individual malfeasance or a serious flaw in the NHS records systemThe main issue behind my complaint in 2015 was the denial of my heart arrhythmia, I just mentioned the MDT report because you seemed to think that records are there just for the asking, and because I had a scan of that ICO letter to hand. You don't get given anything they don't want you to have. Even the ombudsman has publicly panned the NHS for forging records. I can see where mine have been forged.
Much more like vestibular or auditory nerve malfunction.The neurologist who told me that it can't be a brain problem because I get 'headaches' (his word, not mine) sent me to ENT. They said it can't be an ear problem. He sent me to physiotherapy twice. They rejected me twice. Second time I saw him he referred me to an ophthalmologist. She said it's not an eye problem.
you might actually get some insight from SpecsaversI've been to the opticians twice, the second time to ask for a referral to a neuro-ophthalmologist, but she refused and told me to go to the NHS.
I had an appointment with an orthoptist last month, she found that the muscles controlling my left eye aren't working properly. They're controlled by the brain aren't they? The left eye is sluggish, and won't swivel as fast as the right eye, which seems to me to be a pretty good explanation why I find it difficult to judge speed and distance of moving objects, and why I sometimes feel put off balance or want to vomit at the sight of unexpected movement.
In 2021 the neurologist told me that my brain MRI was normal, but that's not what the records say, they mention a brain condition that has symptoms remarkably similar to the ones I'm getting. I had a second MRI in 2022, and after that they put an entry on my records saying that they'd found something "major" but denying me access to it. In the 16 months since then they haven't told me what it's about, and I've been discharged by the neurologist. I asked in writing last year, by recorded delivery, but they didn't answer. I asked the practice manager and got "MRI? What MRI? We don't know anything about any MRI". Since then I've been told that the second MRI was also normal, and that the "Major" entry on my record was a "mistake".
I've just had a letter saying that a new referral back to neurology has been sent for 'review' first before they decide whether they're going to give me an appointment or not.

« on: 11/02/2024 18:31:08 »May I ask what symptoms do you attribute to having had a general anaesthetic?A feeling of extreme pressure in head was the immediate symptom on waking, along with violent dizziness.
Then in the days immediately after, the following developed:
Brain fog, like a cross between conscious sedation and drunkenness
Extreme dizzy attacks, and waking with dizziness & vomiting in the night
Double vision & blurred vision
Difficulty judging speed & distance
The sight of unexpected movement puts me off balance or makes me want to throw up
Inter-pupillary distance (relating to varifocals) changes at random
Bright lights like shooting stars running across my vision
2.5 fold increase in the number of (previously occurring) ocular migraines
Dyspraxia: difficulty writing, slicing food, getting food in my mouth without it falling off fork, cutting myself shaving etc.
Poor reaction to any movement initiated by my own movement
Vomit reflex in diaphragm when swallowing
Random stabbing pains in head & neck
Symptoms are paroxysmal, and tend to be aggravated by anything increasing my blood pressure. (Arguing, straining to do jobs, straining on loo, kneeling etc)
If this question is too personal or intrusive, ignore it.I'm happy to publish just about anything and everything relating to my healthcare, because people who are too coy to do so are just providing the NHS with protection.
Definitely worth a complaint.I never thought of that.
Before you come back with another one I've already done years ago, such as filing a complaint with the Health Ombudsman, you might like to read Hansard, and see what the MPs who created the PHSO had to say about their handiwork:
"The Bill was always drafted to be a swiz, and now it is spelt into the Bill."
"Anyone who contemplates an office of this kind is faced with the dilemma of making it either a Frankenstein or a nonentity?a Frankenstein if it has effective powers and a nonentity if it has not. The Government, quite rightly, has opted for its being a nonentity, and in that sense it is a fraud....I congratulate the Government on its being a nonentity. A Frankenstein would, I think, have undermined the power of Ministers and would have undermined the authority of individual Members of Parliament. That, I am quite sure, is not to be.....My ultimate conclusion about this Bill is that it is a noble facade without anything behind it."
PHSOtheFacts is a pressure group campaigning against the PHSO corruption (they have given evidence in parliament, and to the HSIB, they're not just kids blogging from their bedrooms). In 2018 their lawyers filed 32 cases of Misconduct In Public Office with Scotland Yard, but the investigation had to be abandoned, not because there was no evidence, but because the Health Service Commissioners Act prevents the police, or anyone else, from accessing PHSO files.
Here are the series of reports on the PHSO commissioned by Katherine Murphy, CEO of the Patients' Association. They were taken down from the website as soon as they'd got rid of her.

TLDR? Here's a summary. I can tick off the top 12 of those from my own personal experience.
("Communication takes too long" looks innocuous enough on the face of it, but it's a deliberate ploy to run you out of time on the Statute of Limitations. They ambush you with the final report a few days before the 3 year limit expires.)
The NHS complaints system is a sham, and above the law, just as the MPs who created it intended.
Paragraph 9.37 of the PHSO Service Model Main Guidance is interesting:
"Where we have found that an injustice arose in consequence of maladministration or service failure but that it was fully remedied before the complaint was received by the Ombudsman then a complaint will not be upheld. (Policy requirement)"
So as you can see, all the NHS have to do to get a complaint dismissed is to claim the problem has already been fixed:
"Yes, your Honour, it was me who robbed the Nat West last month, but I've stopped robbing banks now."
"Oh, that's OK then, off you go."
And just in case the NHS are in any doubt what they need to do, this is an email from a PHSO Caseworker coaching the hospital what to say.
My original complaint in 2015 was made because cardiology deliberately lied, and denied any knowledge of my having been diagnosed with atrial fibrillation. After the PHSO went through the pretence of an investigation, and produced a report which ignored all the evidence without explanation, whilst accepting the NHS account at face value with no evidence at all, I wrote a long reply systematically dismantling it, piece by piece. They then conceded it was "flawed" and agreed to re-investigate.
After many months, they then withdrew their previous letter, saying that the second investigation had been stopped in order to "manage" the "legal risks".
I now appear to have become the unluckiest patient in the NHS, as every encounter I've had with the NHS since then seems to have resulted in my being harmed. It's like being one of the Post Office workers but worse: there's nowhere to escape from the NHS.

« on: 10/02/2024 14:17:22 »If you don't ask, you'll never know. Not "the NHS" (which is mostly accountants nowadays) but the doctor who made the statement.When I do ask I never know either, and I don't know who the doctor was, they're all locums, so you never get the same one twice, and they never introduce themselves. The usual response to verbal questions is "I don't know, nothing to do with me, go away and ask someone else", and written questions sent by recorded delivery get ignored.
I'd quite like to know why I still haven't been given the pulmonary vein isolation I was offered ten years ago, and what the "Major" condition was that they discovered from a brain MRI 16 months ago, but both of those questions have been met by the responses above. I'd also quite like to see the 27 page MDT report into my bowel tumour, but they're withholding it because "the pages are all blank".
Etc etc etc......
Meanwhile, you seem to think I'm the village idiot who doesn't even have the initiative to ask them a question.
Before you come back with some other patronising suggestion such as making a complaint, all this is what the NHS do to patients in revenge for complaining.
The reason I came on here looking for independent information is to be forearmed when they start lying to me next time I speak to them.
