If you own an AirPort base station, you can use the Timed Access feature to control the days and times when users access the Internet. This could come in handy in a variety of situations. For example, if you own a cafe and provide free wi-fi access, you can configure the AirPort to block all access to the Internet when your business is closed. And if you have children, you can set time limits for specific devices in your home.

There are two ways to use the timed access feature. You can create a default allow policy to allow all devices to access the Internet at any time, and then specify custom schedules for specific devices. Or you can create a default deny policy to prevent all devices from accessing the Internet according the schedule you specify, and then exempt specific devices by creating custom schedules.

Here's how to control AirPort network access with time limits:

1. Open the AirPort Utility application. (It's in Applications → Utilities.) The window shown below appears.
   
   
2. Click the AirPort Extreme's icon. The status pop-up window appears.
   
   
3. Click Edit. The settings window appears.
   
   
4. Select the Network tab. The window shown below appears.
   
   
5. Select the Enable Access Control checkbox.
   
   
6. Click Timed Access Control. The window shown below appears.
   
   
7. Select the Unlimited (default) option. By default, this allows all of the devices connected to your AirPort to access the Internet all day, every day, but you can change this to block Internet access for all devices (except the ones you specify later) during the times you set.
   
   
8. If you'd like to limit the days and times that a specific device can access the Internet, click the + button under the Wireless Clients field. The window shown below appears.
   
   
9. Enter a name for the device in the Description field.
   
   
10. Enter the device's MAC address in the MAC Address field. You can use the following tutorials to find the device's MAC address.
    
    • How to Find Your Mac's MAC Address
    • How to Find Your iPad's MAC Address
    • How to Find Your iPhone's MAC Address
    
    
11. Use the + button under the Wireless Access Times field to create a schedule for this device's Internet access.
    
    
12. Once you've added all of your devices and customized the schedules, click Save.
    
    
13. Click Update. The AirPort will restart to apply the changes.

Congratulations! You have successfully set time limits for the devices connecting to your AirPort network. The schedule you created is effective immediately.

Temperature is that one measurement that’s dictated by governmental regulations to prove that you have a kill step in your process. Beyond that, there are rules for keeping fresh food under a certain temperature to keep it safe both in transit and storage, and—just as important—maintain its quality so you don’t have to throw it out prematurely.

Modeling the behavior of a prototype cantilevered X-ray adaptive mirror (held from one end) demonstrates its potential for use on high-performance X-ray beamlines. Similar adaptive mirrors are used on X-ray beamlines to compensate optical aberrations, control wavefronts and tune mirror focal distances at will. Controlled by 1D arrays of piezoceramic actuators, these glancing-incidence mirrors can provide nanometre-scale surface shape adjustment capabilities. However, significant engineering challenges remain for mounting them with low distortion and low environmental sensitivity. Finite-element analysis is used to predict the micron-scale full actuation surface shape from each channel and then linear modeling is applied to investigate the mirrors' ability to reach target profiles. Using either uniform or arbitrary spatial weighting, actuator voltages are optimized using a Moore–Penrose matrix inverse, or pseudoinverse, revealing a spatial dependence on the shape fitting with increasing fidelity farther from the mount.

PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are ubiquitous fluorinated organic compounds found widely in manufactured products, from firefighting foam to stain-resistant carpets. These water- and oil-repellent compounds are known to degrade slowly over time, and have been found in humans, drinking water, and even in Arctic ecosystems.

Within the opening moments of a job interview, your first impression is made. Controlling that impression is often a matter of personal style.

Yes, yes — your personality and skills matter, too. However, if we're talking about ...

Just when we thought we'd never get anything better than Donald Trump grasping that orb, we get this dark-humored, delightfully awkward pic that just oozes cringe. Naturally, people were ready to flood Twitter with some entertaining captions. 

As wildfires continue to ravage the West Coast, President Trump has been quick to dismiss climate change as one of the root causes, stating that countries in Europe like Austria don't suffer from wildfires because Europeans live in "forest cities" that are "managed better" yet are "more explosive" than the trees in California.

We're not entirely sure what any of that means, and apparently neither do memers, so please enjoy the following memes about "forest cities" in Austria.

A gas- and vapour-pressure control system synchronized with the continuous data acquisition of millisecond high-resolution powder diffraction measurements was developed to study structural change processes in gas storage and reaction materials such as metal organic framework compounds, zeolite and layered double hydroxide. The apparatus, which can be set up on beamline BL02B2 at SPring-8, mainly comprises a pressure control system of gases and vapour, a gas cell for a capillary sample, and six one-dimensional solid-state (MYTHEN) detectors. The pressure control system can be remotely controlled via developed software connected to a diffraction measurement system and can be operated in the closed gas and vapour line system. By using the temperature-control system on the sample, high-resolution powder diffraction data can be obtained under gas and vapour pressures ranging from 1 Pa to 130 kPa in temperatures ranging from 30 to 1473 K. This system enables one to perform automatic and high-throughput in situ X-ray powder diffraction experiments even at extremely low pressures. Furthermore, this developed system is useful for studying crystal structures during the adsorption/desorption processes, as acquired by millisecond and continuous powder diffraction measurements. The acquisition of diffraction data can be synchronized with the control of the pressure with a high frame rate of up to 100 Hz. In situ and time-resolved powder diffraction measurements are demonstrated for nanoporous Cu coordination polymer in various gas and vapour atmospheres.

Assessing the potential of new environmental management tools often brings an ???innovation dilemma???: is it better to stick with what is known to work, or to implement new measures that are potentially more effective, but also more uncertain? Researchers have proposed an approach to deal with these dilemmas, and applied it to the case study of an invasive species programme in the US.

The North American pine wood nematode (PWN), Bursaphelenchus xylophilus, is a pest worm species that causes a disease known as pine wilt. It was discovered for the first time in the EU in Portuguese forests in 1999. Today, the entire territory of Portugal is demarcated for the presence of PWN, with a 20 km buffer zone, free from the pest, established along the Spanish border with the aim of preventing its further spread. The spread and establishment of PWN in the rest of EU territory is very likely if no strict measures are taken, as required by Decision 2012/535/EU of the European Commission, with serious economic and environmental consequences. To date, Spain has experienced five outbreaks of PWN, three of which have been successfully eradicated thanks to the EU measures and the effective work of the Spanish forest administration; and two outbreaks are currently being eradicated.
