You can tell a lot about a neighborhood by its grocery store parking lot, and how many carts that get put back in the corral.

I remember when it was keys, pager, cigarettes. I miss the simple life.
With the new gasket, it pulls down beyond what the little $12 vacuum gage can measure. Low earth orbit level vacuum for a total of around 100 bucks.
Silicone RTV seal on the vaccuum rig wasn’t very smooth, wouldn’t hold a vaccuum when the pump was off. Scraped it out and poured a urethane one.
A five-year old’s brain is an energy monster. It uses twice as much glucose (the energy that fuels the brain) as that of a full-grown adult, a new study led by Northwestern University anthropologists has found.
The study helps to solve the long-standing mystery of why human children grow so slowly compared with our closest animal relatives.
It shows that energy funneled to the brain dominates the human body’s metabolism early in life and is likely the reason why humans grow at a pace more typical of a reptile than a mammal during childhood.
Results of the study will be published the week of Aug. 25 in the journal Proceedings of the National Academy of Sciences.
"Our findings suggest that our bodies can’t afford to grow faster during the toddler and childhood years because a huge quantity of resources is required to fuel the developing human brain," said Christopher Kuzawa, first author of the study and a professor of anthropology at Northwestern’s Weinberg College of Arts and Sciences. "As humans we have so much to learn, and that learning requires a complex and energy-hungry brain."
Kuzawa also is a faculty fellow at the Institute for Policy Research at Northwestern.
The study is the first to pool existing PET and MRI brain scan data — which measure glucose uptake and brain volume, respectively — to show that the ages when the brain gobbles the most resources are also the ages when body growth is slowest. At 4 years of age, when this “brain drain” is at its peak and body growth slows to its minimum, the brain burns through resources at a rate equivalent to 66 percent of what the entire body uses at rest.
The findings support a long-standing hypothesis in anthropology that children grow so slowly, and are dependent for so long, because the human body needs to shunt a huge fraction of its resources to the brain during childhood, leaving little to be devoted to body growth. It also helps explain some common observations that many parents may have.
"After a certain age it becomes difficult to guess a toddler or young child’s age by their size," Kuzawa said. "Instead you have to listen to their speech and watch their behavior. Our study suggests that this is no accident. Body growth grinds nearly to a halt at the ages when brain development is happening at a lightning pace, because the brain is sapping up the available resources."
It was previously believed that the brain’s resource burden on the body was largest at birth, when the size of the brain relative to the body is greatest. The researchers found instead that the brain maxes out its glucose use at age 5. At age 4 the brain consumes glucose at a rate comparable to 66 percent of the body’s resting metabolic rate (or more than 40 percent of the body’s total energy expenditure).
"The mid-childhood peak in brain costs has to do with the fact that synapses, connections in the brain, max out at this age, when we learn so many of the things we need to know to be successful humans," Kuzawa said.
"At its peak in childhood, the brain burns through two-thirds of the calories the entire body uses at rest, much more than other primate species," said William Leonard, co-author of the study. "To compensate for these heavy energy demands of our big brains, children grow more slowly and are less physically active during this age range. Our findings strongly suggest that humans evolved to grow slowly during this time in order to free up fuel for our expensive, busy childhood brains."
Pour day! Quantum Silicones QM262, deaerating is messy. Need to slow it down next time.
Thread mills are utilized to produce internal and external threads utilizing helical milling to produce the desired thread profile. Thread mills are typically carbide, and smaller in diameter than their corresponding tap would be, thus enabling them to fit within the ID of the pre-drilled hole. 3-axis CNC machines are required to use thread mills.

THE BEGINNINGS OF KAWAII
No, no, you have no idea. It actually IS the beginning of the whole so-called “kawaii culture”. And it started because girls started using mechanical pencils, which provided fine handwriting. After being banished (more precisely, during the 80s), this kind of writing started being used in products like magazines and make-up. And, during this time, icons we usually associate with the whole kawaii industry (like the characters from Sanrio) came to life too.
And what many people don’t realize is that this subculture was born as a way for young girls to express themselves in their own way. And it was also used as something against the adult life and the traditional culture, often seen as dull and boring and oppressive. By embracing cuteness, these young girls (and adult women, after a while) were showing non-conformation with the current standards.
So yep. Kawaii is important, and it all started with cute, simple handwritting a few hearts and cat faces in some girls’ school notebooks <3
NO OK THIS IS SO IMPORTANT!
This is also how the kawaii fashions started! Girls began dressing in cute and off beat styles for themsleves, they were criticized by adult figures telling them “you’ll never find a husband if you dress that way!” to which they began to reply “Good!”
All the japanese subcultures and fashions that evolved out of this became a rebellion to tradition and the starch gender roles and expectations the adults were forcing on the younger generations. As early as the 70s and still to this day you’ll see an emphasis on child-like fashion and themes in more kawaii styles and the dismissal of the male gaze with styles like lolita (a lot of western people assume lolita is somehow sexual due to the name of the fashion, but ask any japanese lolita and they will tell you that men hate the style and find it unattractive which is sometimes a large reason they gravitate towards the style - they can express their femininity and individuality while remaining independent and without the pressure to appeal to men)
Its so so so important to understand the hyper cute and ‘odd’ fashions of Japanese girls carry such a huge message of feminism and reclaiming of their own lives.
so are you telling me that Japan’s punk phase was really the kawaii phase
