For space missions that venture beyond low Earth orbit, new challenges include how to provide basic needs for crew members without resupply missions from the ground. NASA is developing life support systems that can regenerate or recycle consumables such as food, air, and water and is testing them on the International Space Station.

ECLSS is a combination of hardware that includes a Water Recovery System. This system collects wastewater and sends it to the Water Processor Assembly (WPA), which produces drinkable water. One specialized component uses advanced dehumidifiers to capture moisture released into the cabin air from crew breath and sweat.

All the collected water is treated by the WPA. It first uses a series of specialized filters, then a catalytic reactor that breaks down any trace contaminants that remain. Sensors check the water purity and unacceptable water is reprocessed. The system also adds iodine to the acceptable water to prevent microbial growth and stores it, ready for the crew to use. Each crew member needs about a gallon of water per day for consumption, food preparation, and hygiene such as brushing teeth.

The team acknowledges that the idea of drinking recycled urine might make some people squeamish. But they stress that the end result is far superior to what municipal water systems produce on the ground.

A big part of successfully waking up to your alarm is understanding your body and what works for you. Your ringtone may be one of the things that is not working for you. The kind of ringtone that you use is a big factor in how difficult or how easy it may be to wake up. A tone that is too soft may not wake you up promptly, whereas a tone that is too harsh may not motivate you to wake up at all. Try out a few over the course of a couple nights and decide which tone you like best.

Drinking too much water may cause bathroom trips throughout the night which can interfere with sleep. It is important to stay hydrated because that directly affects the amount of sleep you get, but try not to drink more than a glass a night.

 Billions of gallons of oil industry wastewater have been dumped into California aquifers for drinking water and farming irrigation, according to documents we obtained. Check out our interactive map.

Abstract:Achieving urban water security is a major challenge for many countries. While several studies have assessed water security at a regional level, many studies have also emphasized the lack of assessment of water security and application of measures to achieve it at the urban level. Recent studies that have focused on measuring urban water security are not holistic, and there is still no agreed-upon understanding of how to operationalize and identify an assessment framework to measure the current state and dynamics of water security. At present, there is also no clearly defined and widely endorsed definition of urban water security. To address this challenge, this study provides a systematic approach to better understand urban water security, with a working definition and an assessment framework to be applied in peri-urban and urban areas. The proposed working definition of urban water security is based on the United Nations (UN) sustainable development goal on water and sanitation and the human rights on water and sanitation. It captures issues of urban-level technical, environmental, and socio-economic indicators that emphasize credibility, legitimacy, and salience. The assessment framework depends on four main dimensions to achieve urban water security: Drinking water and human beings, ecosystem, climate change and water-related hazards, and socio-economic factors (DECS). The framework further enables the analysis of relationships and trade-off between urbanization and water security, as well as between DECS indicators. Applying this framework will help governments, policy-makers, and water stakeholders to target scant resources more effectively and sustainably. The study reveals that achieving urban water security requires a holistic and integrated approach with collaborative stakeholders to provide a meaningful way to improve understanding and managing urban water security.Keywords: urban water security; drinking water; sanitation; ecosystem; socio-economic; climate change; water-scarce cities

Remember when water and iPhones couldn't mix? Pools, tubs, and toilets would suck down the working iPhones of clumsy and careless owners and spit out expensive paperweights like they were nothing. Times have changed, however, and the newest iPhones can take a swim without fear of certain death. But a dip in liquid can still cause muffled music and audio from the speakers.

Enter shortcuts. They allow both developers and general users alike to patch together simple-to-complex tasks for iPhones to process. The best part? Shortcuts can be uploaded to the internet and shared with anyone using the Shortcuts app. And there is a good one for ejecting water from an iPhone's speakers.

The iPhone XS, XS Max, 11, 11 Pro, 11 Pro Max, 12, 12 mini, 12 Pro, 12 Pro Max, 13, 13 mini, 13 Pro, and 13 Pro Max are IP68 water resistant, but the iPhone 7, 7 Plus, 8, 8 Plus, X, XR, SE (2nd gen.), and SE (3rd gen.) are all IP67.

While the IP67 models are still preferable to the ones that came before them regarding water protection, it certainly doesn't equate to waterproof. In fact, IP68 isn't technically "waterproof" either, just better protected than IP67. Because of this, we highly discourage you from dunking your iPhone underwater intentionally, as water damage is not covered under Apple's warranty.

While there likely exists more than one shortcut to tackle the issue, we keep coming back to the one created by Josh0678, which has been around for almost four years now. The shortcut acts much like the water eject tool on Apple Watches. When run, it plays a very bassy tone for about ten seconds, shaking water both out of the speaker as well as from the outside of the device.

When you get water in your iPhone's speakers, you can use any of the above methods to activate Water Eject. To do so from the Shortcuts app, open the "Shortcuts" tab (iOS 16) or "My Library" tab (iOS 15 and older), then tap the "Water Eject" card (as seen in Step 1).

If you genuinely do have water stuck in your speaker, you should see it begin to either leak or spray out of the bottom of your iPhone. We recommend holding your iPhone at a bit of an angle, with your speaker facing the floor, as this can help force the water out of your speaker better.

Like the automatic process, if there's water in your speaker, you should see it begin to either leak or spray out of the bottom of your iPhone. Hold your device at an angle with your speaker facing the floor to help guide the water out.

As you can see, the shortcut does a pretty good job ejecting water from your iPhone's speaker. However, it isn't perfect and will leave some remnants in the speaker after the tone has finished playing. You can keep using the shortcut until you feel all the water is gone.

This shortcut isn't the only way to get water out of your iPhone's speaker. If you'd rather go through a solution found in the App Store, check out the Sonic app. It invokes a similar strategy to "Eject Water," but unlike shortcuts, passed through Apple's rigorous standards for its iOS marketplace.

It was a drizzling evening, I adventured in and around the wetland as the rain dropped on my umbrella. There were some drastic changes in the wetland looking back at old photos of it. The grasses, sedges, and rushes (such as soft rushes) grew more, greener, and taller. Many European water-horehounds grew, they had long, toothed, and opposite leaves and were found in the water. The trees at a distance, such as black cottonwoods, grew so many more green leaves. The invasive species yellow flag iris also started to take space in the wetland. Not captured in the photos, many red osier dogwoods, Pacific ninebark, grey willow, cattails, and many others were flourishing on the other side of the wetland, providing food and shelter for the animals. As time went from April to June, I noticed more eastern cottontails emerged in the area.

The stream carried sand and gravel, and there could be clay near these streams (5). The stream provided a water source for plants and animals and a habitat for invertebrates and so on. It was more chilly near the water, keeping the temperature cooler and the ground wetter at the bottom of the hill, while it was drier at the top of the hill since it received more sunlight. Going higher up, I saw a few barred owls (6) resting quietly in chestnut trees with their eyes closed. They seemed to be more comfortable with humans than some other smaller birds which got scared away more easily. They had horizontal brown bars around the neck and vertical brown bars on the belly, and were barred brown and white overall. I also observed a squirrel (7) feeding on flowers from another chestnut tree, so fluffy and cute! There were some erratics (8) here and there, which were once deposited by glaciers.

A killdeer was walking on a fallen log in the water for a short period of time, wandered for a couple of minutes in the grass, and later flew away. It had two thick black bands around its neck, a white belly, and a brown back, wings, and legs. ff782bc1db
