Coronavirus, a slightly skewed reflection on a tiny rascal

CoronavirusFirst and foremost, this is a purely philosophical consideration and has absolutely nothing to do with medicine. Nothing mentioned here should be interpreted as advice on contagion or as treatment for illness. Follow the advice of the public health institute and the local recommendations given by doctors and healthcare personnel.

Viruses and bacteria are a nuisance; can't we just eradicate them all? It can be tempting to think that way, because viruses and bacteria are the cause of many ailments and deaths. But unfortunately, it's not that simple. Both bacteria and viruses have their place in nature, and we depend on them. It is bacteria that break down dead organic material so that it can be reused. It is fungi, bacteria, and protozoa that live in the rumen and break down the cellulose in grass so that cows, sheep, and other ruminants can get nutrition. Human digestion also depends on microorganisms. In the large intestine, there are many microorganisms that help with digestion. If this bacterial flora is disturbed, one can get an upset stomach. Microorganisms also have a role on the skin and mucous membranes. An American study has concluded that we have more microorganisms on and in our bodies than we have cells in our bodies. But they are so small that they nevertheless only make up about 3 kg of an adult man.

Bacteria and protozoa are quite hardy creatures. As long as they get moisture and nutrients, they can withstand quite a lot. If they don't get these, many of them can hide inside a capsule waiting for better times. But they have an Achilles' heel. They eat! They have a metabolism, and we can trick them by feeding them something they cannot tolerate. For example, penicillin.

The word virus actually means poison. It is a bit worse with viruses. Viruses do not eat. We cannot give them poisonous food. We have to fight them in other ways, preferably by stimulating and supporting the body's own defense against viruses. We can inject antibodies into the blood. The antibodies find the virus particles and bind to them. This prevents the virus from attaching to a cell, and they act as a label that allows the virus to be detected and destroyed by the body's own defense system. The common method is to inject dead or weakened viruses into the body. The virus is not capable of making us sick, but the immune system learns to make antibodies on its own. We call this vaccination. It is a method that can be used against both bacteria and viruses. Once the body has learned to recognize a virus and produce antibodies against it, the immune system remembers this for a shorter or longer time. In some cases, for a lifetime.

But the very best thing is that we don’t let the virus into our bodies at all. We can stay away from those who are infected. We can wash our hands and surfaces. We can disinfect with chemicals or heat. We can use masks and gloves. I mentioned earlier that viruses are fragile things. They consist of a few strands of RNA or DNA, genetic material, which is the recipe for making new virus particles. These are encapsulated in a shell of proteins. The surface of this shell has 'hooks' that can attach to a cell. When that happens, there are mechanisms that open the cell wall and let the genetic material into the cell. There, it takes over the cell's machinery and starts it producing viruses. It continues to do so until the cell bursts and releases all the virus particles, the virions. Viruses are, as I said before, fragile things. It takes little to destroy a virion so that it doesn’t work. Errors also occur in the production process; mutations happen. That is when the genetic material is copied incorrectly. Then the new virus is different from the old one. Almost all mutations fail. They cause the virus to stop working. But occasionally, a rare mutation provides an advantage. It's like winning the lottery – for the virus, that is. Such mutations can make the virus's coat slightly different so that our immune system doesn't recognize it. This is often the case with cold viruses. They mutate so frequently that it's not worth the effort to try to develop a vaccine. The same is true, to some extent, with the flu. We make vaccines, but it's uncertain how effective they are if the virus has changed significantly along the way.

Coronavirus. It got its name because under the microscope it has an aura around it, somewhat resembling how we see the sun through a coronagraph, a special telescope that blocks out the solar disk so that one can study the sun's glowing atmosphere. Corona actually means crown. SARS-CoV-2 is what we call a zoonosis, a pathogen that can infect both animals and humans. It is also considered highly contagious and has a high fatality rate for some of those who become infected.

The world has chosen different strategies to combat this virus, ranging from denying that it exists at all to complete lockdown and isolation. Some countries reacted quickly, some late. Our neighboring country, Sweden, believed that the best approach would be for as many people as possible to get the disease so that natural immunity in the population would occur, the much-discussed herd immunity. That is when so many are immune that those who are infected cannot infect many others, and the infection rate is below one. Then the epidemic will die out. The infection and disease will continue to exist, but not as an epidemic. The infection rate for Norway is currently at 0.66. But that is due to lockdown and isolation measures, not herd immunity. Norway has chosen a strategy of lockdown and isolation. It will not eradicate the disease. It could have done so if it were a limited area. As it stands, the spread is global, and we must assume that even if one were to manage to eradicate the virus in Norway, it would always come back. We simply cannot isolate ourselves from the rest of the world forever.

It will take a very long time for Norway to achieve natural resistance in the population. Due to the strategy we have chosen, few people are infected. To achieve the effect of herd immunity, at least 60% of the population must have antibodies. Nevertheless, I believe Norway has chosen a favorable strategy, provided that a vaccine becomes available within a reasonable time. By vaccinating, immunity is achieved without experiencing the disease.

There is also a big difference in how severely the disease affects each individual. This may be due to some cross-immunity stemming from other illnesses, like flu, colds, etc. Another factor that can play a role is the infectious dose. If a person is exposed to a massive dose of the virus, the body has less chance to fight it compared to if the dose is smaller, allowing the immune system time to respond before a large number of cells are infected. It is also the case that, regardless of the disease, not everyone gets sick. During the Black Death, many fell ill, but not all. The Spanish flu did not affect everyone. Not everyone gets the flu, and not everyone contracted measles, rubella, chickenpox, and so on. Some are naturally immune without any detectable reason.

The pandemic leaves its mark on the economy. When people miss work due to illness or quarantine, it results in losses. We see that many politicians and lobbyists are more concerned about the country's (or their own) economy than about the health of the population. The government is quite generous in handing out saved funds to large, international players while small businesses have to struggle and manage as best they can. Some predict a global recession that will last for decades to come.

The world's wealth is very unevenly distributed. While some wallow in luxury, others are dying of hunger. Could it be time for a revision of our economic systems? We consume the Earth's resources to produce superfluous and unnecessary things. Could it be time to return to the essentials? We travel around the world in search of experiences and entertainment in exotic settings. Could it be time to become a bit more 'introspective' and rather seek amusement in our immediate surroundings? We pull fish from the sea, transport it halfway across the globe to have it processed before sending it back the same way. Could it be time to put an end to such madness? We are so busy that goods are sent by energy-consuming and environmentally damaging trucks instead of by ship or railway.

There are many things that don't add up. Pandemics are certainly not the only problem we are struggling with. Not even the worst.

Energy and movement<

Sometimes, when night falls and the house becomes quiet, thoughts start to wander on their own. Then it can easily happen that curiosity takes complete control and reason, which tells you that it is bedtime, must give way. You examine one thing and along the way discover another thing that needs to be looked into – and so on. Until the night comes to an end and you go about the day in a half-asleep state.

Energy, for example, is something worth thinking about. We are in the process of depleting the Earth's energy resources at an accelerating pace. We have long been aware of this, but we refuse to fully acknowledge it. At least not to a significant degree. Driving electric cars might help a little, but unfortunately it is far too little. We live in a world of denial, along with a firm belief in miracles, that we will be saved when science provides a deus ex machina solution. Unfortunately, this is a phenomenon that belongs in the world of movies and novels. However, it may be that the world is beginning to wake up. If so, it is because of a young woman from Sweden who has made it her mission to awaken the world. Because we need change. Yet at the same time, the idea is associated with fear, for it is likely that these changes will hardly be very comfortable.

But if we let our thoughts spin a little in the night. Have you ever wondered how far a car could drive if it ran on slices of bread – or oats for that matter? Have you ever wondered how much gasoline you would need if we humans could run on gasoline?

Fortunately, the situation is such that we still have enough energy to run the internet. There, one can easily find basic data by doing a quick Google search. First, I looked at the daily energy requirements. From the Norwegian Health Informatics website, I obtained the daily energy requirements for women and men under different conditions, as shown in the table below. The energy requirements were given in kilocalories, a useless unit for calculations, so I immediately converted it to joules (kilojoules) and then to the amount of gasoline that contains the same amount of energy.

OBJECTACTIVITYENERGY

activ work2302<7td>96380,304

As shown by the table, we animals are considerably more efficient than machines. Yes, we are animals too, mammals and warm-blooded. Cold-blooded animals that do not use their energy to maintain body temperature are even more energy-efficient than us, but that can wait for another night. We do have an impressively low consumption – less than half a liter per day. Imagine how much gasoline it would have taken to build the pyramids if all the workers were gasoline-powered?

Then I also visited a website belonging to Ingrid Kristiansen. To reassure people who know me: I don't usually frequent such sites. It was just a one-time occurrence and solely for the purpose of finding information. What I learned on that site is how much energy we use on different activities.

ACTIVITYEnergy/hour

Running 10 km/h660662760,009
Running 15 km/h1080723010,01

Once again, one is amazed at how efficient we are. We also see that the most effective way to move is to walk – not run.

But what if we build an engine that runs on whole-grain bread with yellow cheese (without butter)? How much fuel would that require?

Many cars today consume about half a liter per ten kilometers. But gasoline engines are not particularly efficient. They have an efficiency of 20% (perhaps a little better with new engines, but in this calculation, we use 20%). This means that most of the energy is wasted as heat. Only 0.01 liters go towards moving the car forward one kilometer. That corresponds to an energy of 0.088 kWh, which in turn corresponds to 757 kcal. A slice of whole-grain bread with yellow cheese has an energy content of 152 kcal. This means that this car with a bread engine would need to chew through almost five slices of bread per kilometer. Then one would need to load a significant amount of fuel to drive a trip to Tromsø. Maybe one would also need to bring a stoker to feed this greedy machine. I really think we are going to have to scrap the car as a means of transport.

Comments. I have made it quite difficult to post comments on this page. This is to avoid having to clean out all those who try to sneak in shady links on the site. Comments are welcome via email. (click here) or post on Facebook page mine (opens in a new tab). Let's just hope that no major calculation errors have crept in!

About bees and men

When it says men in the headline, it means men in the sense of humanity in general, and not at all male beings of the human species. Otherwise, one might think that I mean the following considerations do not apply to female beings. But they do. The fact is that it sounds much better when one says 'about bees and men' than when one says 'bees and humans.' And besides, it's not just bees we're talking about here, it's also ants, termites, and other creatures that live in the same way.

Bees live in colonies. In beehives when they are 'tame' or in hollow tree trunks or wherever else they find it suitable to exist. A bee can hardly be said to possess much intelligence. From birth, it is intended for specific tasks. Some are guards and ensure that intruders do not enter. Some take care of the young and feed them, some act as living ventilation systems and fan air through the hive when it is hot, or just vibrate their wings to generate heat when it is cold. Some go out to collect honey and pollen. Some are heaters for the queen. The queen, yes. The queen eats and gives birth. That is what queen bees do. And then she controls the other bees by emitting scents.

When looking at bees individually, one can probably detect a certain intelligence. However, most of their behavior is genetically programmed and dictated by the demands of the colony or the queen. One could say they are hardwired and remotely controlled. It is different when looking at the colony as a whole, as a single organism. In a bee colony, most, often all, worker bees are daughters of the queen. Like cells in the body, they are centrally controlled by chemical stimuli. In the body, these are called hormones, but in bees, we call them pheromones. Just like brain cells communicate with each other through synapses, bees also communicate with each other. Brain cells exchange information through chemicals and electrical signals, bees exchange information with each other through scents and through dancing and tail-wagging. When a bee returns home with full loads of nectar, it performs a small dance, and with the direction of the dance and a slight wag of its tail, it tells the other bees which way to go to find good nectar. One might argue that the intelligence of the colony is greater than the sum of its individual members.

Humans may be the animal on Earth with the highest individual intelligence. We do not know for sure; we just believe it. For we have no real way to measure intelligence. It is true, however, that some claim that human intelligence was at its peak around 10,000 years ago and that it is now declining. Sometimes it can be easy to believe that. But what is more important is that humanity as a whole does not act intelligently. We prefer to use our abilities to acquire goods at the expense of others. In the extreme, we kill to live the good life as we wish. We do this surprisingly easily. In fact, we are often willing to go to war and kill simply because someone believes in different stories than we do. We are not capable of using our collective intelligence, if it exists, for the benefit of all humanity. Just look at the issue of climate change. We have long known that our extraction of the Earth's energy resources is not sustainable.

Throughout Earth's history, there have been several mass extinctions. Some global, some more local. A common factor for most of them is that they have been linked to climate change. Insects have had their heyday on Earth. So have reptiles and mammals. Which group is next in line? Is it the insects again? Perhaps the mollusks? Could we witness intelligent shells and literary snails? Philosophical octopuses. Octopuses are already considered highly intelligent, despite lacking a central nervous system. Or is it the machines that will take over? This was a popular theme in the Science Fiction genre in the 1960s and 70s. A superorganism of interconnected computers that secured dominion over the world and kept humans as slaves. Theoretically, this is not impossible. It might even have already happened. For aren't we, to a large extent, good slaves to our machines? Many of us are lost and dysfunctional and fall into a vegetative state the moment the phone is out of battery. If we are to have even the slightest hope of surviving, we must strive to develop a collective intelligence. We simply must become more like the bees.

It may seem as if collective and individual intelligence are in opposition to each other. If one looks at political systems, capitalism is probably the one that best fits high individual intelligence. Everyone can work to acquire benefits. There is minimal regulation and restrictions. It is good for the intelligent and the ruthless, but it is not good for humanity. To avoid stagnation, such a system is based on continuous growth. It becomes like a pyramid scheme. Some profit, but many lose when it collapses. The other extreme is communism. A centrally controlled regime where everyone works according to a plan that is for the benefit of all. In principle, that doesn't sound so bad, but there are problems. Who should decide the plan? How should the consideration for individual people be ensured? What if someone disagrees with the plan and refuses to follow it? We have also seen the phenomenon that power corrupts. The person or people who were supposed to decide and administer such a plan would have infinite power! Socialism is in many ways a middle ground between these. There is a majority that makes the plans and administers them. Limitations are placed on the individual, but there is still considerable freedom. This system is not without problems either. When the Athenians talked about democracy, they meant real democracy. Everyone showed up and discussed the matter, and decisions were made about what should be done. For practical reasons, this is no longer possible. We elect representatives to make decisions on our behalf. But are we sure that these representatives truly represent those who elected them? Are we sure that the representatives are informed enough to make the right choices? And not least, are we informed enough to choose the right representatives? This becomes difficult. Perhaps we need a supercomputer to take over?

All of this can also be viewed on a larger scale. Nations, not individuals. As long as all nations are only concerned with improving their own conditions, usually at the expense of someone else's, it is contrary to the common good of humanity. In reality, we do not have much hope. If only we were a bee. With a completely different view of existence and not least a different perspective on eternity.

But maybe there is still a small glimmer of hope? A Swedish little girl who manages to make the world listen? Let's hope so. Because there is one thing we humans are very good at, and that is hoping!

Svearing

What exactly is swearing? Nowadays, swearing is a hot topic in the comment sections. Apparently, some TV programs started it all. I haven't watched any of these programs, so some might argue that I am not entitled to an opinion on this matter. But as I understand it, it is the Northern Norwegian tendency to spice up their explanations with crude words that do not quite appeal to the more proper part of the population, which primarily resides in the southeastern parts of the country. Some might use the word narrow-minded, but I refrain from doing so. It is after all not their fault that they live in a part of the country where, at best, they can pee in brackish water. As one moves further north and west, the sea becomes saltier, and so does the language.

But what exactly is swearing? Strong language, without a doubt. There are so many different kinds of strong expressions. Sometimes they may just be ordinary, everyday words, but pronounced with such intensity and sincerity that they are perceived as swearing just because of that. Then we have the religious curse words. These usually include both what is in the Bible and what is not. Both the devil and hell are popular themes around which strong expressions are centered. Sexual themes are also popular. In fact, I feel I sense that these are on the rise at the expense of the religious curse words. Personally, I think this is positive, because swear words are generally formed from things we think about. And thinking more about life than death, well, that is good. Because sexuality definitely belongs to life, even though it is precisely sexuality that makes death necessary. But that is a completely different discussion. Devils and their dwellings, on the other hand, belong to death. But even here there is a contradiction. When hell is mentioned, we often imagine a dark, underground place with glowing coals and other torments. But another name for the devil is Lucifer – the bearer of light. And hell, that means the place of light. One might then wonder about these 'mediums' who appear on TV and are supposed to help troubled souls to the other side. They encourage people to 'go towards the light.' But where are they really sending the poor souls?

But now I'm getting sidetracked. Back to swearing. In addition to the fact that swear words are of different kinds, they are used in different ways. They can be used in everyday conversation, often with a humorous touch. They are also a tool you can use when you want to be a bit ironic. Irony is, after all, a highly valued art in Northern Norway. Unfortunately, this irony is not always understood in the southeastern regions. Then there are the genuine, spontaneous outbursts with emotion and real immersion that happen when things suddenly and unexpectedly go wrong. For example, when the nail cowardly bends away so that the hammer hits the thumb with great force and determination. Then some juicy, heartfelt curses, spoken with emphasis and flair, are appropriate. These can, for instance, prevent frustration-driven throwing of hammers, which can easily lead to further injuries. Spontaneous outbursts can also occur as a 'the cup is full' effect after prolonged unresolved frustration. Swearing can also be used to irritate or provoke those around you.Just as teenagers try out swear words at home to explore their boundaries. Swear words used purely for provocation are especially common in comment sections.

Although I am of the opinion that one should limit the use of strong language, especially in polite company, I am of the view that it is a valuable part of the language. Some claim that those who swear have a limited vocabulary. For some, this may certainly be true, although I am far from sure whether there is any correlation between these two things. For others, it is not true at all. There are masters of the art of swearing who can go on for half an hour without a single repetition. Unfortunately, swearing in English-language films is a shaky matter. Mostly, there are two words that recur: 'bloody' and 'fuck.' Nor does hip-hop culture impress. Of course, it is both provocative and offensive to be accused of—or encouraged to—have intercourse with one's own mother, but honestly, when the same word appears every other second, it is reasonable to suspect the 'poets' of having a very limited vocabulary.

Just as there are differences in how swearing is delivered, there are also differences in how it is perceived. For those who do not understand or cannot share the emotional expression that genuine thumb-slap exclamations convey, or do not understand the humor in a story sprinkled with juicy exaggerations and reinforcing auxiliary words, it will likely seem flat and unnecessary. Therefore, great demands are placed on the storyteller to adapt their choice of words to both the audience and the occasion. As Krestjan the first mate said to the pastor when he was reprimanded for 'banding and rotten speech': «De kan nok gå an for Jær, Prost, for om I står på stolen å om kjeften forskjær sæ for Jær, så kan I slå en kremt i han, å så kan I ta Jær att igjen. Det bi’kje sålessen før mæ, nei. Når æ skal løp galleasen i hamn me høgrokke plystre i vevlingan, då bi de kje før mæ å slå nokka kremt i’an.»  (sitat fra Vett og Uvett av Einar K. Aas og Peter Wessel Zapffe)

When it comes to swearing on TV, it is indeed difficult to control who sees and hears it. In such cases, it's more about adjusting the language to the situation. Take, for example, Oluf Rallkattli (Arthur Arntzen, a master of humor). He uses a lot of forceful expressions, but little or no swear words. There are also requirements for the audience. The easily offended should probably seek another type of entertainment. Surely there are those who find it directly unpleasant to listen to. I feel the same way about some TV programs. There is a simple cure for this: just don’t watch or listen. But it is also permissible to have an opinion on the matter and express it, for example in a comment section. Then I think that such opinions should also be met with respect. There is no need for name-calling and characterizing opponents. You can disagree without degrading the other party. Bold expressions are allowed to everyone, as stated in the Constitution §100 (it's not exactly what it says, but it's close enough). It should also have stated that humorous expressions are all permitted (including some strong language).

Long live stubbornness.

If anyone is wondering how it happens that the seagull can fly, I can tell you right now. It's pure and unadulterated STUBBORNNESS! That flapping of the wings is just for show. No, he flies on pure stubbornness. He's even more stubborn than the wi… well, let's leave that unmentioned. But in any case, he's the most stubborn thing you can wrap in feathers.
I have now politely tried to talk properly with him and persuade him to move his nest and breeding site to places other than my porch. There should be plenty of suitable places in the local area for nest building.
For a while, I thought he was aiming for a mobile existence, because every morning I found straw and twigs and things like that on the car roof. But here yesterday evening, quite late yesterday evening, actually long after a reasonable bedtime, I was letting the cat out. Then I realized what was going on. They are doing their thing on the car roof. So the arrangement with straw and twigs is probably just to prevent the flat-footed ones from slipping on the slippery roof. It’s probably nice to get a little push-off when the seagulls are at their worst.

I had now convinced myself that it was too late for this pair of seagulls. They haven’t had it easy this year, being homeless and chased around as they have been. Twice, their egg has been taken from them. I thought the season was lost for them. But not at all. When I saw the activities they were up to on the car roof, I realized there was more to come. And sure enough, this afternoon when we came home from work, they had made a nice little nest bowl. Where to? Well, I can tell you. In the other flower box on the steps. Well, not ON the steps, as it hangs outside the railing, but still. No egg has been laid yet, but the intention is clear.

That stubborn bird!

Larissa

Larissa, and not to forget her mate, Larris. Last year they settled on the garage roof, right at the edge, where they took turns incubating a single egg. Eventually, out came a little gray-green speckled downy chick, and the seagull-like happiness was immense. Yes, we shared, more or less, the excitement over the little one. But both Larris and Larissa became quite grumpy and quarrelsome. Not to mention loud-mouthed. There was screeching and scolding like no other whenever someone went out the door. Well, we thought, it won’t last that long. But it did. The fairly flat garage roof with asbestos-cement sheets was a perfect nursery for the seagull chick. There was busy traffic to and from with treats for the growing family. Every time the feeding express had a free moment, there was either loud choral singing from the roof ridge or dive-bombing after the cat or other creatures unfortunate enough to be in what they clearly defined as a forbidden area. However, it must be admitted that the residents of the house had a kind of free pass to move around the area as long as they stuck to ordinary, everyday tasks. Except for the house cat. The cat developed acute agoraphobia. It eased a little over the winter, only to be replaced by a touch of cryophobia, but now the agoapphobia has flared up again.
The maternity ward on the garage roof eventually turned into a kindergarten, preschool, elementary school, and finally a middle school. Every day when we came home from work, the little one was the first thing we looked for, to see if it had jumped down. But we were disappointed—every day. We even set up an old foam mattress to soften the fall, but it didn't help.

But suddenly one day, he was both able to fly and confirmed and almost an adult, and then he was gone. Peace settled over the courtyard, and we could once again welcome visitors without equipping them with helmets and hearing protection. It was in that context that I had a serious talk with Larris and clearly warned him that we would not tolerate this. They were evicted from the garage roof and were welcome to find another breeding place.
Then winter passed and spring came. And with spring, two clearly spring-crazed little seagulls: Larissa and Larris. They were busy with what seagulls do on bright spring nights. Such springtime gull activities eventually lead to an intense urge to build a nest, and the serious talk we had had was obviously forgotten. I felt compelled to put power behind my words and demanded the removal of the illegal structures. After two or three attempts, I realized that stronger measures were needed. A seagull-scaring owl was purchased. 'Greets passersby with blinking eyes and a friendly hoot,' it said on the box. Friendly hoot? By now, we were well past the friendly phase. The owl looked so plastic and unconvincing that I was embarrassed to show it to the seagull. It was never set up, just packed away and forgotten. A ladder with a fluttering red plastic bag seemed to do the job. Now it only covers a small part of the garage roof, but fortunately, it seems that it's exactly that spot which is the only suitable seagull nesting site. For it eventually got through the plumage that the garage roof was terra clausa for nesting. In sheer desperation, Larris set up an emergency nest in a flower box outside the steps. It was high time, because as soon as the last straw was laid, an egg plopped out. Now it may be that they got very busy 'charging' the next egg, and less concerned with taking care of the one they had, for the next morning the egg was gone without a trace. 'What do we do now, little dove?' said Larris. 'Pressure's building up, it's building up, hurry, hurry,' said Larissa. She couldn’t scream out the proper seagull way, because she was afraid the egg would just pop out. Larris understood that there was urgency, so he arranged some straw in the nearest flowerpot so she could relieve herself. And there they lie now, Larissa and their egg. Yes, Larris is diligent and takes his turn incubating too. He has a slightly milder temperament than Larissa. She is more short-tempered, especially if someone surprises her. Otherwise, they have become quite friendly while incubating. Even the cat is quietly tolerated. Well, quietly might be an exaggeration. Using an indoor voice is not something seagulls are good at. But one thing is certain: when the egg hatches, the area will be evacuated fairly quickly. No seagull chicks get to sit in peace until they are capable of flying, and even more so. (I hope)


Update: Today, when we got home from work, a small tragedy had occurred. The seagull was lying on its nest but took off immediately when I swung into the driveway. Otherwise, they have not been so easily disturbed. They have stayed put and incubated diligently even when we stood on the porch just a meter away. Something had happened here, I thought. Then I went up to the porch and saw this:

Life is sometimes quite short – especially a seagull's life that has not yet come out of the shell. We suspect that it might be the magpie that is to blame. It has a nest up in the tree right next to the stairs and has a full view of everything the seagull might be doing. Perhaps it has been lying in wait and struck in an unguarded moment. The misdeed must have happened quite recently, I suppose. Then we'll see what happens next. If the seagull gives up, it lays a new egg in the nest or finds a new nesting place.

Vita brevis, acuta rostro!

Biological wastewater treatment

Vi produserer store mengder avløpsvann hver dag. Alt vann som kommer inn i boligen skal jo ut igjen. Og det tar med seg masse annet som vi vil bli kvitt. Vannet fra toalettet kaller vi gjerne svartvann. Det inneholder urea og fæces. Dette vannet inneholder mye tørrstoff, mange næringsstoffer og har en stor bakterieflora. Også gråvann, som kommer fra dusjing, vasking og fra kjøkkenet, inneholder litt tørrstoff og plantenæringstoffer, men har en betydelig lavere bakterieflora.
Hvordan kan en så rense dette. Vi har tradisjon for å blande alt sammen. Det kan imidlertid være fordeler ved å holde de separert for så å ha en enklere renseprosess for gråvannet.
Det første trinn i renseprosessen er mekanisk. De faste stoffene må bort. Bunnfelling og/eller filtrering tar seg av dette. Eventuelt kan en her tilsette kjemikalier for at forurensningene skal slå seg sammen – flokkulere – slik at de lettere lar seg bunnfelle eller filtrere. Men da må en forholde seg til disse kjemikaliene i den videre prosessen, og en må kontroll på restkjemikalier hvis vannet skal brukes til drikkevann. Etter at det meste av tørrstoffer er fjernet, så må nitrogen og fosfor fjernes. Begge er næringsstoffer som planter trenger. Vannet kan derfor brukes direkte til å gjødsle planter med. Likeens kan tørrstoffet brukes til plantegjødsel, eventuelt etter en modningsprosess. Det vannet som ikke brukes til gjødsling av planter sildres over biokropper. Biokropper er plastlegemer som har en stor overflate som dekkes av en biofilm, et bakteriebelegg som lever av næringsstoffene i vannet. Når belegget når en viss tykkelse fjernes det. Dette kan gjøres automatisk ved at et visst antall legemer tas ut hver dag og spyles rene. Den biofilmen som spyles av er også utmerket til å dyrke planter i. Den kan også være «mat» for mikroorganismer som produserer bioetanol eller biodiesel.
Til slutt filtreres vannet og desinfiseres. Det kan skje ved tilsetting av klor eller hydrogenperoksyd eller det kan bestråles med UV-lys som tar knekken på de mikroorganismene som måtte være igjen. Så er det bare å drikke vannet med god samvittighet. Dette er naturens egen måte å rense vann på – nåja, en av naturens egen metoder.

New webcam

Endelig er et nytt webkamera oppe å gå. Dette er et såkalt «bullet»-kamera. Det har en ytterkappe som tåler vær og vind. Det hadde ikke det forrige, det var et kamera beregnet for innendørsbruk. Det var da også montert inne i garasjen, men jeg hadde laget et hull i garasjeveggen som det kunne se ut gjennom. Dermed ble jo også synsfeltet noe begrenset.
Dette kameraet er montert ute, oppe på veggen, og har en mye bedre utsikt. Det vil si, jeg må justere det opp slik at det viser litt mer av himmelen. Det skal jeg gjøre neste gang jeg går forbi. Kameraet ser mot Furøy og Gottesjord. Det blir fint til våren når solen kommer igjen og skinner i bakkene på Gottesjord.
Nå er det jo mørkt store deler av døgnet, og da er det jo ikke så mye å se, foruten lysene på andre siden. Kameraet har ir-belysning for å lyse opp forgrunnen. Det er bare det at det er ikke noe forgrunn. Jeg har likevel latt ir-belysningen stå på, fordi den gjør det lett å se om det er nedbør selv i mørket. Hvis det er hvite striper som går over bildet, så regner eller snør det. Hvis stripene er vannrette, så der det i tillegg vind.
Kameraet tar bilder hvert 10. minutt. Det kan ta opptil 5 minutter fra bildet er tatt til det legger ute. Bildene sendes til weatherunderground, og der kan en se tidligere bilder, og man kan se en time-lpse video for hver dag.
Her er webkameraet direkte
Og her finner en videoer og mer
Bildene fra mitt webkamera er fritt for alle til å bruke til alle aktverdige formål. Hvis de brukes vil jeg gjerne at det medfølger en liten kildehenvisning.
Have fun!

-Men hvor lenge var Adam i paradis? Kameraet sluttet å fungere etter få dager. Tåler det ikke frost, kanskje. Veldig irriterende, men sånn er det vel når man kjøper billig fra wish. Fortsettelse følger . . .

Encrypted connection

Nå er det lagt til et SSL- sertifikat på siden min. Det betyr bare at forbindelsen er kryptert, ingen kan snappe opp underveis det som sendes mellom serveren og mottageren. Egentlig litt overflødig på en slik side, men sertifikat på dette nivået er gratis hos ISP’en min. Så slipper man å få melding om at forbindelsen er usikker. Og best av alt, man får jo et kult, grønt hengelås i adresselinjen. Fancy!

Choice

Så er det igjen tid for den kvadrenniale seremonien som skal legitimere stortingspolitikernes eksistens. Det er valg – tid for å stille dem til ansvar for de katastrofer de har nedkalt over det norske folk og verden forøvrig. Dessverre virker det som om politikerne blir mere og mere opptatt av makt og posisjoner som fenomen og ikke som et middel til å tjene dem de representerer. Det bidrar igjen til det fenomenet, at færre og færre finner det bryet verdt å levere sin stemme. Det er jo heller ikke så lett å sile vekk all valgkampstøyen og finne ut hva man i realiteten kan forvente av påfunn fra de forskjellige partier. Det dreier seg stort sett om å finne det minste av de tilgjengelige onder.

Noen ganger ønsker vi bare forandring. Noe annet enn det som har vært. Det går ikke alltid så godt. Se bare på USA. De ønsket tydeligvis noe annerledes. Vi andre holder pusten og håper verden overlever. Skjønt vi har vel ikke så mye å være stolte av vi heller. En En bergensk sandpåstrøer som er travelt opptatt med å strø sand der løshundene hennes har vært og pisset eller gjort det som verre er.

Jeg synes denne regjeringen har vært en katastrofe. Ikke når det gjelder økonomi eller levekår. Slike ting er nå stort sett uavhengig av politikerne. Når det går bra, så er det helst til tross for – og ikke på grunn av politikerne. Og når det ikke går godt, så har de samme politikerne fint lite å stille opp med. Det er alltid den menige hop som må bla opp og betale regningen uansett. Nei, katastrofen er at de har gjort slik at man skjemmes av å måtte fortelle at man er norsk. De snakker om verdier, men kaster vrak på alle idealer som finnes, både norske og internasjonale.

Vi har ikke demokrati i Norge. Det finnes vel knapt noe land i verden som kan skryte av å ha ekte demokrati. Bystatene i det gamle Grekeland hadde det. Ekte demokrati lar seg vel neppe oppskalere til å fungere for et helt land. I stedet har vi noe som kalles representativt demokrati.

Vi velger de som skal være våre representanter. La oss velge verdige representanter, representanter vi kan kjennes med. Det aller minste er at de må ha et minimum av folkeskikk.

Men viktigst av alt: Gjør et valg!

Godt valg
