    Over the decades, our politicians decided to challenge Doctors from being a Salary positions into a business and in so doing, created our Doctor’s from caring for its patients to how they are going to paying their bills with all kinds of different incentives on a pay scale.

    They need you unhealthy to survive in this monetary system.

    Hence the different health programs and testing in a multitude of areas.

    Our common sense and logic has been eroded over the decades especially when you can’t question the push for vaccines.

    A sick person pays far better than anyone who is healthy.

    I have seen this happening in many areas.

    What got me into this line of thinking….

    A farmer shot a nuisance Bear and the Game wardens said they had to take it as they were afraid it could create an incentive to go out and shoot more.

      Not sure that is totally correct Jojodogfacedboy.

      Two big changes;
      1. Medicare. Free treatment for all. Before that you either paid for treatment or went to a charitable hospital.

      The scheme was created in 1975 by the Whitlam Government under the name “Medibank”

      2. hospitals was removing specialist ‘honorary’ appointments, ie work for free to salaried positions at hospitals which occurred during the 1970-80s.

      Of course an honorary appointment brought prestige, which could be monetised in one’s private practice. The doctors were brought more under the control of the hospital management and ‘medical independence’ suffered.

    “Everyone knew it would eventually happen and today is the day. In an effort to influence the 2020 U.S. election, Facebook, Instagram, YouTube, Twitter and the social media technocrats have crossed the Rubicon today and banned all sharing of the explosive information about Hunter and Joe Biden’s self-serving deals with Ukraine.”

    “The Automatic Climate Lawsuit Generator”

    “The Washington Free Beacon has an ongoing series of “I forced a bot to …” parodies making fun of predictable robot-like reactions from biased journalists or far-left activists to particular hot topics. Seriously, however, it might be worthy of genuine speculation as to whether the Sher Edling law firm has a bot writer program to punch out boilerplate-similar global warming lawsuits. I actually speculated about that back when I wrote my dissection of their second round of simultaneously-filed lawsuits, where I detailed the fatal fault of their lawsuits’ enslavement to the worthless “reposition global warming” memos. The repeats galore continue in their latest Delaware v. BP filing.”

    Anyone care to hazard a guess of the brightest spot on earth on 30 July 2020?

    If you think Greenland then you are close but it was not the brightest on that day or in that week:
    https://1drv.ms/u/s!Aq1iAj8Yo7jNg20rmI6ZbdeTV0c9

    How many climate scientists would pick a tropical latitude in the middle of the North Atlantic Ocean as being the brightest spot on Earth at any time; let alone the peak of the boreal summermid . How many climate models produce clouds capable of rejecting 336W/sq.m or 80% of the incident insolation. So powerful in reflecting heat input with the sun directly overhead that the ocean surface below is actually losing heat and cooling.

    Then, if you know the conditions that create cloudburst leading to cyclonic storms above latitudes of 10 degrees latitude, is surface temperature dependent would you have concern for catastrophic global warming.

    Cyclonic storms are not the consequence of climate change, they are the thermostat that regulates the maximum temperature. There is a physical limit on ocean surface temperature rising above 32C. It is not physically possible for the ocean surface to exceed 32C. The shutters go up before that temperature is reached and the sunlight cannot penetrate to the surface.

    Most of the bright spots along the tropical band in the image are all high altitude storm clouds limiting the ocean surface temperature by reflecting sunlight.

    Any climate model that has CO2 leading to catastrophic warming is unphysical garbage – it would have to defy the laws of atmospheric physics that produce cloudbursts and that can never happen while oceans exist and the sun remains to heat them.

        I believe I have it nailed. The key is understanding the nature of atmospheric physics that give rise to CAPE. The process is important to pilots of small aircraft as it is the basis of cloud bursts. This gives some understanding:
        https://study.com/academy/lesson/convective-available-potential-energy-cape-definition-use-in-forecasting.html
        or for more detail
        https://en.wikipedia.org/wiki/Convective_available_potential_energy

        Over the years I have developed a reasonably accurate atmospheric model. I am able to use that to calculate CAPE and the conditions needed for the lifted level of free convection. One of the surprising aspects for me is how tightly linked the lifted level of free convection is linked to TPW independent of surface temperature. Any atmosphere where TPW exceeds 30mm will have a lifted level of free convection. I am yet to find any other reference to this fact so that may be new knowledge.

        The 30mm TPW threshold gives great insight to some of the conditions around the globe. A key one is that the Persian Gulf is the warmest body of connected water surface on the planet that achieves a surface temperature above 32C. It is the exception that proves the rule. It rarely exceeds the 30mm TPW necessary for lifted level of free convection so rarely gets into tropical storm mode. It is simply too land locked to allow the TPW to achieve the threshold.

        It is very clear that climate models, relying on cloud parameterisation rather than cloud physics, give the wrong answer. So much of the output from climate models is unphysical garbage and will remain so until they have the high vertical resolution layered models needed to produce unstable atmospheres.

          It is worth noting that any climate model producing any part of the ocean surface warmer than 32C, other than the Persian Guif or similarly land locked connected water surface, is giving the WRONG answer – it is unphysical and cannot happen. As the surface temperature approached 32C, those glowing areas that provide the SPF 100+ SPF ocean shield would be springing up everywhere to never permit that temperature. That white glow in the linked image gives a sense of the unbounded power of cyclonic storms to reflect heat.

          Hi RickWill,
          If you look at BoM’s MetEye, http://www.bom.gov.au/australia/meteye/?ref=ftr it is already showing sea surface temperatures that are unbelievable.
          I have a MetEye image of 06/02/2018 that shows Gulf of Carpentaria, Darwin, all the waters around the Solomons, Bismark Sea, at 32-34. I once swam at Siar Island Bismarck Sea in mid-summer. Yes, it was warm, but not that warm. More BoM bunk I think.

            Martin
            I really appreciate this observation as it helps verify the physics involved.

            I think you have the legend colours confused. If you click over the Gulf, the maximum I could find is 29C. Even with this being somewhat land locked I expect it would reach the 30mm TPW for cloud burst. The portion just to the southwest of Darwin is 30C but that will still have dry air from the land taking water away so may not reach the cloud burst threshold until the monsoon hits Darwin.

            I worked in Karumba for a few months through this time of the year and it is about this time of year the monsoon sets in and cools the place down. Late October into early November was unbearably dry and hot for most people.

            There is no actual data for areas north of PNG, just the colour coding, which is not easy to discriminate between ranges. The frequency of cyclonic storms increase as the temperature approaches 32C and they prevent heat from getting to the surface. It has been a reasonably active year for storms in the South China Sea. There were certainly heavy monsoonal rains in China earlier in the year.

            If you have other references to actual surface temperatures I would be interested. I am using the satellite data and the only region that stands out on the 1 degree grid is the Persian Gulf. It appears to have always have less than 30mm TPW because it is land locked so will not achieve the conditions essential for cloud burst. The Gulf of Carpentaria certainly gets cloud bursts. I have seen them roll in all the way down to Karumba at the bottom of the Gulf.

    Regarding the ‘October Surprise’ dropped today in the US, Giuliani says that this is just the start, and there is a lot more on the way. I assume with a whole laptop hard drive at their disposal, there would potentially be a lot of information, and a good political hit is one that grabs attention at first, but then keeps dripping information to keep the story alive.

    A whole laptop hard drive…just think what might be kept there. Work documents, emails, text messages from your iPhone backups. Giuliani has been preparing for this for almost a year. I’m sure there are a lot of plans for the upcoming days.

    There appears to be no legal recourse whatsoever for the Biden’s to block this. It’s not just in the hands of the FBI, but Giuliani has his own copy.

    Just like the Weiner laptop, but this time the FBI can’t bury it.

    A couple of interesting things : ( the articles appear to be quite detailed including diagrams etc )

    “The tiny tweak behind COVID-19 vaccines
    “Prepandemic coronavirus research by Jason McLellan and Barney Graham led to a trick for stabilizing the prefusion form of spike proteins
    “by Ryan Cross
    “SEPTEMBER 29, 2020 | APPEARED IN VOLUME 98, ISSUE 38

    “But there’s a third, more subtle secret to their success: a tiny but oh-so-important tweak to a critical viral component called the spike protein.

    “The RSV work showed that the protein sequence is not nearly as important as the protein conformation.

    “Barney Graham, deputy director of the Vaccine Research Center, National Institute of Allergy and Infectious Diseases
    Viruses multiply by dumping their genes into our cells and hijacking our cellular machinery to crank out new virus particles. But first, they need a doorway into our cells. Coronaviruses are studded with spikes, which grab hold of proteins decorating our own cells like doorknobs. Once attached, the spike undergoes a dramatic transformation, stretching before partially turning inside out to forcefully fuse with our cells.

    “Scientists believe that for COVID-19 vaccines to be effective, our immune systems must develop antibodies that prevent this fusion. Such antibodies must target the spike protein in its aptly named prefusion conformation. Unfortunately for vaccine developers, spike proteins are liable to spring from their stubby prefusion shape into their elongated postfusion form on a hair trigger.

    https://cen.acs.org/biological-chemistry/infectious-disease/Small-molecule-takes-aim-RNA/98/i39?utm_source=NonMember&utm_medium=Newsletter&utm_campaign=CEN

    “Scientists have identified a potential target for therapeutics against SARS-CoV-2, the virus that causes COVID-19. The discovery hinges on a small molecule that latches onto and inhibits a structure in the SARS-CoV-2 RNA genome, preventing the virus from pumping out the proteins it uses to replicate and infect cells (ACS Cent. Sci. 2020, DOI: 10.1021/acscentsci.0c00984). Although it may take years before any therapeutic could be developed from the proof-of-concept work, the approach could be helpful in battling coronaviruses in the future.

    “In general, drug discovery and development efforts have largely focused on proteins, says Milka Kostic, a chemical and structural biologist at Dana Farber Cancer Institute, who was not involved with this study. Scientists know less about RNA’s structure and how to target it, they add. But “there could be advantages to intercepting RNA” instead of going after the proteins made from it, Kostic says. Past efforts at targeting the RNA of viruses have taken a similar approach to bind the RNA of hepatitis C and ongoing work is exploring HIV as another RNA target.

    “Matthew D. Disney, a chemical biologist at the Scripps Research Institute, and his team screened thousands of molecules and tested how well a handful of these compounds bound to a fold of viral RNA that is unique to SARS-CoV-2. The virus depends on this hairpin to control the translation of certain key proteins. Using cells into which that bit of RNA had been introduced, the researchers found that one molecule, a quinazolinamine, stuck to the structure and gummed up the works, reducing expression of a gene it controls by about 25%. “It’s an extremely high-affinity, drug-like small molecule,” Disney says. “That was a little surprising to me.”

    After reading this , you may look at things with a bit of a side glance.

    Fascinating reading on the current mental plague upon our houses…..

    https://consentfactory.org/2020/10/13/the-covidian-cult/

    “Looking in from the dominant culture (or back through time in the case of the Nazis), the delusional nature of these official narratives is glaringly obvious to most rational people. What many people fail to understand is that to those who fall prey to them (whether individual cult members or entire totalitarian societies) such narratives do not register as psychotic. On the contrary, they feel entirely normal. Everything in their social “reality” reifies and reaffirms the narrative, and anything that challenges or contradicts it is perceived as an existential threat.

    “These narratives are invariably paranoid, portraying the cult as threatened or persecuted by an evil enemy or antagonistic force which only unquestioning conformity to the cult’s ideology can save its members from. It makes little difference whether this antagonist is mainstream culture, body thetans, counter-revolutionaries, Jews, or a virus. The point is not the identity of the enemy. The point is the atmosphere of paranoia and hysteria the official narrative generates, which keeps the cult members (or the society) compliant.

    “In addition to being paranoid, these narratives are often internally inconsistent, illogical, and … well, just completely ridiculous.

      Of course these graphs never show y=0 on the graph, vastly exaggerating the significance of what is a tiny variation. If shown at the right scale you would wonder why anyone bothered. The total area is around 3 in 25 or 12% at any time from the highest extent to lowest. Then if you reduce that because you are measuring area, not distance, it is even lower. It is close to fake news, blown up out of all proportion, a thin skin on an ocean on average 3.5km deep. All the sea ice could melt tomorrow and the sea would not rise a micron.

      I suppose it works on the common but wrong perception that air temperature is the core driver of ‘climate’ when in fact it is water temperature, as we know from La Nina, El Nino, The Gulf Stream, the Humboldt Stream. Air temperature is simply an artifact, not a direct cause and the heat capacity of the ocean mass is 1400x that of the thin air above. Sea ice is hardly of any significance except to shipping and only in the Northern Hemisphere. It is important to note that in the Arctic the average year round is exactly 0C so ice extent can and does vary wildly and mean precisely nothing.

        The North Pole can reach 13C in peak summer. Murmansk in Russia at 69 Degrees has a lovely summer and can reach 33C.

        Meanwhile the maximum temperature at the South Pole is only -12C. Australia’s Mawson base is 67 degrees and in peak summer only reaches 2.5C. Even this is because it is at sea level where most of Antarctica is at 3.5Km high.

        So conflating the North and South Poles, or the Northern Hemisphere and Southern Hemisphere as if they were same is just wrong. How then does anyone talk about a world temperature at year 1900? No idea. Especially as the Australia’s BOM leaves the pre 1911 records alone. A proper examination (without homogenization) might actually show a cooler planet, but who wants that?

          We know it was cooler around 1900.

          ‘The average global annual temperature hovered around 13.7 °C (56.7 °F) from the 1880s through the 1910s. During the 1920s to 1940s, temperatures climbed about 0.1 °C (0.18 °F) each decade.’

          In regards to sea ice in both hemispheres, ocean currents are the main drivers in determining ice extent.

              The average global annual temperature. Again, who measured that in the 1880s? And what sort of accuracy did they quote for a planet which is 75% covered in water?

                Consider Antarctica is an impenetrable continent as big as South America and 3.4Km in the air which is -25C in summer and someone knows the temperature of Antarctica in 1880? Who? Even the entire oceans South of the Tropic of Capricorn when only 2% of the world’s population lives there today? Who measured that temperature, a region which is about 90% water?

                It’s a wonderful thing science. You can come up with the temperatures of places no one has ever been, or did they have satellites in the 19th century?

                I would love the BOM to properly analyse the actual records they have from 1780 to 1911 and give a real picture at least of Australia. I suspect the Federation drought was longer and hotter than the Millenium drought, but that would be very embarassing.

                I have enough trouble with even the concept of a ‘world temperature’ averaged over day and night, winter and summer and all latitudes from the North Pole to the South Pole without someone telling me they know the actual temperature of the planet to 0.1C. At best such a temperature is a construction for the purpose of rough comparison but to pretend it is a real and accurate temperature is absurd. Even to say it is ‘cooler’ or ‘warmer’ to an accuracy of 0.1C is not rational science.

    Another one for the “tell ‘em their dreamin’ file for climate scientists-

    The total ocean heat uptake this century, assuming reliable measurement to the 0.01C accuracy to detect that change, is only 65% of the heat rejected from oceans in the single month of January 2020.

    That gives an indication of the power of Earth’s shutters that start getting deployed at ocean surface temp of 24C and are SPF 100+ above 27C.

    If a massive meteor made it through Earth’s atmosphere and landed in an ocean to cause tremendous heating, the resulting cloud cover would block sunlight from the surface until the surface temperature fell below 32C. There may be other issues to worry about like big waves and lack of vitamin D but permanent temperature rise will not be one of them. In fact, overcorrection due to lagging rate of condensing is more probable and the Earth actually cooling; Younger Dryas style maybe?

    Masks should not be worn when exercising.
    ‘In conclusion, exercise with facemasks may increase the risk of SCD via the development of acute and/or intermittent hypoxia and hypercapnia. The hypothesized mechanisms include increased adrenergic stimulation, increased oxidative stress leading to electrophysiological abnormalities that promote arrhythmias via non-reentrant and re-entrant mechanisms. Given the interplay of multiple variables contributing to the increased arrhythmic risk, we advise avoidance of a facemask during high intensity exercise, or if wearing of a mask is mandatory, exercise intensity should remain low to avoid precipitation of lethal arrhythmias. However, we cannot exclude the possibility of anarrhythmic substrate even with low intensity exercise especially in those with established chronic cardiovascular disease in whom baseline electrophysiological abnormalities may be found’

    I posted this late on the last story so will repost here as not many people will otherwise see it.

    I find it interesting that traditionally the Left were opposed to “Big Pharma” and the Right, recognising the huge investment required to create new drugs supported them.

    Now, the Left see COVID as a means to fulfil their dream of population control and economic destruction of the West. They therefore reject simple cheap cures and support a vaccine which will take a long time, if it comes at all. Meanwhile people in the West will remain under moderate (most of world) to extreme levels of restrictions (e.g. Victoriastan).

    The Right generally accept the scientific evidence for the efficacy of the simple cheap treatments like vit D, zinc, HCQ, ivermectin and others.

    The Right want to be free, the Left want tyranny and control.

    Half of Great Barrier Reef dead since 1995

    A new report by the Australian Research Council has found that the Great Barrier Reef has lost more than half of its corals since 1995.

    The ARC Centre of Excellence for Coral Reef Studies research showed the reef’s small, medium and large coral populations had all declined over the past three decades, largely due to bleaching events in 2016 and 2017.

          i hoped you’d worked that out for yourself as it is fairly self-evidence. Without going back to the original to double check the context and to put it simply-

          according to them, in the past there was a degree of certainty for recovery from an set back as bad conditions for recovery were rare and likely spaced far enough apart for recovery to occur. Now, they claim, they are of such frequency that there may not be time.

          The relevance of the older fecund corals is that they are a large contributer to the individuals that will recolonise open niches.

            Then they are only guessing that these ‘disturbance events’ are novel and going to get worse because of increasing CO2.

                yup. Sort of supports those who point out that the LIA is not global

                No matter what Michael Mann thinks, it was a time of global cooling.

                ‘The General Crisis of the Seventeenth Century in Europe was a period of inclement weather, crop failure, economic hardship, extreme inter-group violence, and high mortality causally linked to the Little Ice Age. Episodes of social instability track the cooling with a time lap of up to 15 years, and many developed into armed conflicts, such as the Thirty Years’ War (1618–1648).’ wiki

                How does it do that?

        Until leaf gets back … interesting to ponder the cyclic nature of bleaching.

        ‘Here, we use linear extensions from 44 overlapping GBR coral cores to extend the observational bleaching record by reconstructing temperature-induced bleaching patterns over 381 years spanning 1620–2001. Porites spp. corals exhibited variable bleaching patterns with bleaching frequency (number of bleaching years per decade) increasing (1620–1753), decreasing (1754–1820), and increasing (1821–2001) again. Bleaching prevalence (the proportion of cores exhibiting bleaching) fell (1670–1774) before increasing by 10% since the late 1790s concurrent with positive temperature anomalies, placing recently observed increases in GBR coral bleaching into a wider context.’

    Oxygen level inside masks is lower than OHSA standards.

    It doesn’t seem to cause hypoxia in most people wearing most masks and not too physically active, but some people test low using oximeters. I suspect hypercapnia is more of a problem. Pity there isn’t a cheap CO2 meter available like the oximeters.

      Oximeters measure oxygen bound to hemoglobin including the oxygen molecules in carbon dioxide bound to hemoglobin as carboxyhemoglobin. 10-29% of CO2 in the blood is carboxyhemoglobin (from different sources).
      ‘Pulse oximeters have some limitations. They can only employ light at two wavelengths. Thus the devices can only distinguish between hemoglobin and oxygenated hemoglobin. When carboxyhemoglobin and methemoglobin are also present, there are two additional wavelengths required for differentiation. In the presence of elevated carboxyhemoglobin levels, pulse oximetry overestimates the true saturation of oxygen as carboxyhemoglobin binds with a higher affinity than oxygen’
      https://www.ncbi.nlm.nih.gov/books/NBK539754/
      As oxygen in the mask drops, and more CO2 is re-breathed, oxygen saturation may drop but carboxyhemoglobin increases and gives a false high oximeter reading. An oximeter may indicate ok oxygen saturation, but that doesn’t mean the oximeter user doesn’t have both hypoxia and hypercapnia.

    I believe Peta Credlin should be nominated for Victorian of the year in 2021. She has been unrelenting in guiding the inquiry into the hotel quarantine shambles. Her efforts to get phone conversations released to the inquiry demonstrated pure brilliance; effectively cornering Dopi Dan with his own ego. She has brought brilliant background in politics and public service into her reporting role – as a commentator, she is second to none; hugely insightful. She is the antithesis of modern journalists. She highlights how dim the light shines in the brains of ABC reporters.

    Dan threw Mikakos under the bus but Peta Credlin’s efforts have now pushed Emergency Management Commissioner, Andrew Crisp into indefinite leave. Getting the telephone conversations to the inquiry resulted in Head of DPC, Chis Eccles resigning. She now has Jobs Minister Martin Pakula in her sights. Gradually getting to the last man standing.

    Mark Knight, the Herald Sun cartoonist, had a brilliant cartoon today. One panel is Dan in full attack mode castigating the truck driver who spread CV19 into northern Victoria but failed to fully recall details of his travels. The other panel was the much more introverted Dan at the hotel inquiry simply stating “I know nothing”. Talk about double standards, threatening to send police after the truck driver for not telling the whole story while pleading complete ignorance to something he would have micro managed to the finest detail.

    Peta Credlin’s questioning this week really had the wind up Dan. She pumped up his already inflated ego about his attention to detail in getting the facts together every day to present at the news conference and the way he appeared to be in total control of the agenda, Dan even smirking with embarrassment; then she asked why a person with such obvious attention to detail would leave such critical matters as hotel quarantine security to others – Dan was like a cornered rat.

    For those who do not know Peta Credlin, this is one of her news reports:

      Wow, nasty situation – Who could have predicted that!

      Good news for Wartsilla though. They are specialists at getting the power supply industry out of a bind. Their latest stuff is tri-fuel:
      https://www.wartsila.com/marine/build/engines-and-generating-sets/dual-fuel-engines/wartsila-50df
      Although demand for these beasts is growing fast as owners of WDGs come to understand the harsh reality that no one ever predicted or, if they did, the diversity fairy would solve that minor issue.

      Interestingly batteries and diesel generators cost about the same capital per unity of power. The energy component of batteries is often supplied at negative cost while the energy component for diesel has only been negative cost once in my living memory. Of course one generates power while the other own stores. The energy capacity component beyond 2 hours at rating is VERY expensive. A modern, planet saving utility would give their customers the bird and go with batteries rather than diesels.

    Everything the Democrats accused Trump of doing they were apparently doing themselves. Classical Saul Alinsky, who is copying Lenin himself…..

    Sorry if this is a duplicate post from above (no, I did not have time to scan through; hope to spend some time perusing the thread at a later time):

    Ran across this, supposedly from the BBC:

    Everything the LEFT accused the RIGHT of doing they were apparently doing themselves……History lesson 101.

    Regarding Twitter and FB as a platform, I have recently come across Gab (gab.com) – a relatively new platform with about 500,000 subscribers (one more since I found it). It does not censor and may be the answer.

    Does anyone have the current score card on Hydroxychloroquine?

    The last study I saw was a double blind study on prophylaxis in health care workers. Apparently no benefit but the number were quite small and only 4 positive cases in each arm of the study.
    How come the clinical information seems to support the use of HCQ but the studies are not so good?

    US President Campaign—What do the polls say?
    Corey Lewandowski who was Trump’s campaign manager until May of 2016 gave his assessment on what we know about the election, coming in less than three weeks. He appeared on Fox and Friends, the morning program on FoxNews, this Friday in New York City.

    He noted that in three key battleground states, the rolling average of polls on the web site RealClearPolitics, finds that Trump is doing better than 2016. And in private polling, the findings are considerably better than that. And not just in these states but nationally. But it could be close for now.

    The traditional key battleground states on which the election turns have long been the states of Florida and Ohio. The other close indicator states that will be first to report on November 3rd are North Carolina and New Hampshire.

    But what Team Trump did in 2016 through identifying Democrats attending Trump rally’s was to
    to exploit disaffected Democrat voters and make them turn out for the new President.

    The goal of the current election, which will be significantly if not massively outspent again, is to get these and similar voters to vote for President Trump in the so-called Rust Belt states because they were the manufacturing heartland that Democrats abandoned beginning in 2004.

    Thus, the new battleground states are Pennsylvania, Michigan, Wisconsin, and possibly Minnesota.

    That’s my report. Optimism, yes! But get out and take a friend or neighbour.

    Rudi Giuliani said in an interview:

    ‘Back in 2014, the Obama administration prohibited the U.S. from giving money to any laboratory, including in the U.S., that was fooling around with these viruses. Prohibited. Despite that, Dr. Fauci gave $3.7 million to the Wuhan laboratory. And then even after the State Department issued reports about how unsafe that laboratory was, and how suspicious they were in the way they were developing a virus that could be transmitted to humans, we never pulled that money.’ (wuwt)
