#High temperatures

[sapphic-sprite]

It’s been record breaking high temperatures all over the world for the last couple months so I’d like to implore y’all to please check the warnings on your medications. I know personally one of my medications makes me sensitive to natural/artificial sunlight and the other makes me more susceptible to being dehydrated. SSRIs, commonly, can make you heat intolerant. Make sure you are checking the reactions that your medications can have so you don’t end up in the hospital as summer is not over and we will continue to have increasingly high temperatures.

hi guys, does anyone from a place with warm summers have any tips for dealing with heat in the city?

I'm living in a swiss city where it's 28-33C (82-92F) with 50-75% humidity for weeks at a time in summer, and I'm guessing this will only get worse in the future summers. Places here don't have AC, it's just not something that is done here, and I'm working a desk job with some movement in a 28C/82F office and coming home to an equally warm apartment.

Does anyone have any tips for managing heat (on a budget)? Sending this out into tumblr hoping someone from warm regions can help me. It's fine for me currently (though tough) but I might have a cat coming over on-and-off again so i want to keep the heat down when it's at mine.

Extreme heat is wilting and burning forests, making it harder to curb climate change. (Washington Post)

Earth’s land lost much of their ability to absorb the carbon dioxide humans pumped into the air last year, according to a new study that is causing concern among climate scientists that a crucial damper on climate change underwent an unprecedented deterioration.

Temperatures in 2023 were so high — and the droughts and wildfires that came with them were so severe — that forests in various parts of the world wilted and burnedenough to have degraded the ability of the land to lock away carbon dioxide and act as a check on global warming, the study said.

The scientists behind the research, which focuses on 2023, caution that their findings are preliminary. But the work represents a disturbing data point — one that, if it turns into a trend, spells trouble for the planet and the people on it.

“We have to be, of course, careful because it’s just one year,” said Philippe Ciais, a scientist at France’s Laboratory of Climate and Environmental Sciences who co-authored the new research.

Earth’s continents act as what is known as a carbon sink. The carbon dioxide that humans emit through activities such as burning fossil fuels and making cement encourages the growth of plants, which in turn absorb a portion of those greenhouse gases and lock them in wood and soil. Without this help from forests, climate change would be worse than what is already occurring.

“This is a significant issue, because we are benefiting from the uptake of carbon,” said Robert Rohde, chief scientist for Berkeley Earth, who was not involved in the research. “Otherwise, carbon dioxide levels in the atmosphere would rise even faster and drive up temperatures even faster.”

Ciais and his colleagues saw that the concentration of CO2 measured at an observatory on Mauna Loa in Hawaii and elsewhere spiked in 2023, even though global fossil fuel emissions increased only modestly last year in comparison. That mismatch suggests that there was an “unprecedented weakening” in the Earth’s ability to absorb carbon, the researchers wrote.

The scientists then used satellite data and models for vegetative growth to try to pinpoint where the carbon sink was weakening. The team spotted abnormal losses of carbon in the drought-stricken Amazon and Southeast Asia as well as in the boreal forests of Canada, where record-breaking wildfires burned through tens of millions of acres.

With the temperatures rising, don't forget the animals around you!

Heat Wave of 34°C is coming tomorrow in my hometown!

Look, is March now and Fall hasn’t come yet, at least, in temperature. I hate Fall and I hate Winter the most.

I don’t want it to arrive!

But...when the temperature is this hot outside, in my theatre school’s inside is even hotter! ‘Cause we have just tin roofs and we don’t have air conditioners.

We can’t afford them.

And worst of all, I have the double of physical activities than I had last year.

So, a friendly advice from the Caribbean countries always is: avoid noon time.

If you are able to plan your day ahead, either choose the early hours or the hours where the sun is well past it's zenith to go out of your house/job/etc. and into the streets. It will help you avoid the worst hours of the days.

They also take naps during noon precisely because it's nearly impossible to do anything around those midday hours but not everyone can take one or benefit from one so I leave that to your consideration :P

i need to go get groceries but there's Temperature outside :(

Challenges in lubrication of bearings exposed to high temperatures.

Case study on impact of high temperatures and loads on lubrication and therefore life of plummer block bearings in the drying range of a textile spinning mill.

The drying range or VDR (Vertical Drying Range) in the woven dyeing and printing segment of a textile mill enables rapid drying of fabric under high steam pressures and temperatures. The pillow or plummer block bearings play an important role in functioning of these vertical drying ranges by supporting movement of rotating shafts or rolls.

These vertically oriented plummer block bearings face unique operating conditions of high temperatures and loads, exposure to process chemicals, steam, dust and other contaminants. In the absence of effective lubrication, environmental factors can cause undue stress on the plummer block bearings, leading to premature failure and unexpected downtime in the drying section.

Selection of lubricant to endure such aggressive conditions determines the performance and life of functional elements in bearings like rollers, raceways, balls, and cages. BECHEM’s range of speciality greases for bearings operating in such harsh conditions ensure effective lubrication and also extend bearing service life.

Customer: A leading textile producer in India with a value chain extending from yarns to garments. With a production capacity of over 75,000 meters of fabric per day, the integrated textile unit has multiple facilities for the processes of bleaching, mercerizing, dyeing, printing of yarn, garment washing and finishing in the same vicinity.

The drying range is equipped with 16 vertically mounted cylinders in two rows. The customer was using a synthetic grease based on OE recommendation (brand Y) to lubricate a total of 32 bearings in each row.

Issues reported by the Maintenance Dept.

Excessive oil bleeding and evaporation loss due to exposure to high temperatures

When exposed to hot steam, grease oxidised rapidly losing its inherent properties

Frequent re-lubrication

In order to avoid plummer blocks going dry, re-lubrication frequency was increased. However, the process was tedious as bearings are located at different heights and in difficult-to-reach locations

Nevertheless, frequent bearing failures were reported leading to downtime and productivity loss

Operating conditions of ‘vertical drying range (VDR) cylinder

1st row and 2nd row with 16 cylinders vertically mounted in each row

Bearing number: UC 215 bearing

Temperature: 150 to 180 ˚C

Load: 1- 1.5 Ton

RPM: very low

Re-lubrication frequency: once in 15 days

Bearing life: 1 year

Closely monitoring the operational parameters, BECHEM’s application team recommended the high temperature grease, Berutemp M 2 KN. A high-performance, polyurea grease developed for bearings that are exposed to high temperatures and loads, steam and water ingress.

Why Berutemp M 2 KN?

Based on polyurea thickener and fortified with additives, Berutemp M 2 KN offers exceptional oxidation stability ensuring long term lubrication.

Extended service life of the grease avoids repetitive lubrication breaks and production loss

Berutemp M 2 KN forms a consistent lubrication film between rolling contact and sliding surfaces even at high temperatures

Berutemp M 2 KN offers excellent resistance to water and steam, thereby protects rolling elements from corrosion

Formulated with ultra-refined base oil, Berutemp M 2 KN exhibits excellent temperature resistance behavior with controlled oil bleed characteristics

Developed on comparatively higher base oil viscosity (490 Cst at 40 ˚C), Berutemp M2 KN prevents metal-to-metal contact under high load conditions

Based on the BECHEM team’s recommendation, a trial was initiated with Berutemp M2 KN to observe any change in lubrication life.

Trial Observations:

No issue of grease oxidation when exposed to steam was reported

Re- lubrication interval extended from 15 to 30 days

No bearing failure reported in the drier section of the plant for a span of 1 year

Having observed performance of the product in optimizing production process efficiency, the customer switched over to ‘Berutemp M 2 KN’. Usage of grease was also extended to other bearings which were exposed to high operating temperatures and similar work environments.

Georgi and Glashow thus suggested that at these high energies and temperatures there was complete symmetry among the three nongravitational-force particles, and hence complete symmetry among the three nongravitational forces.¹¹

11. The mathematically inclined reader should note that Georgi and Glashow's grand unified theory was based on the group SU(5), which includes SU(3), the group associated with the strong nuclear force, and also SU(2) × U(1), the group associated with the electroweak force. Since then, physicists have studied the implications of other potential grand unified groups, such as SO(10) and E6.

OK SUMMER YOU CAN STOP NOW

I LOVE U BUT PLEASE STOP

We had a similar heat wave here in Canada a year or two ago. It was awful. I had a big plastic tub for storing stuff that I emptied out and put water in with some big ice packs and set it under my computer so I could stick my feet in it when I worked. It helped so much with keeping me cool. Highly recommend!
