![]() ![]() A combination of the above two mentioned electron transfer processed affords the three-membered metallacycle complex IV. In this case, a more electron-deficient metal centre is favoured for the electron transfer from oxygen atom to transition metal. Meanwhile, complex III should be more stable, since CO 2 acts as a bidentate ligand with two oxygen atoms. ![]() Adduct II (end-on type) seems less plausible due to the weak interaction between the lone pair of only one oxygen atom and the metal centre. Electron-rich metal centres are more feasible to form these types of complexes via electron transfer from metal centre to carbon atom. More specifically, complex I with an M-C bond is sometimes termed as a metallacarboxylate. If a metal centre reacts with one molecule of CO 2, there are five different chelating modes possible. As a result, a series of transition metal CO 2 complexes are known. In its ground state, carbon dioxide possesses two equivalent C-O bonds that could both coordinate to a transition metal centre. 1) (2) different reaction modes for CO 2 activation (main focus of this review) and (3) potential new applications of CO 2 valorization.Īs shown above, CO 2 has multiple reactive sites: the carbon atom is an electrophilic Lewis acid centre and the oxygen atoms act as weak nucleophilic Lewis base. While classical methods for CO 2 hydrogenation have been reviewed elsewhere and will not be included here 5, 6, 7, the following subjects will be addressed: (1) novel transformations using carbon dioxide (briefly summarized in Fig. A special focus is given on the reaction modes for the CO 2 activation and its application as C1 building block in organic synthesis. This review will describe the most recent advances made in the area of CO 2 valorization-turning CO 2 into a useful chemical feedstock-under mild conditions. To create C-C bonds with CO 2, the use of carbon nucleophiles is specifically limited to strong nucleophilic organolithiums and Grignard reagents, as well as phenolates.Īlong with the rapid development of organometallic chemistry and catalysis (see Box 1), various types of efficient CO 2 transformations in organic synthesis have been discovered in the past decades, greatly improving its efficiency and applicability. In particular, the catalytic coupling of CO 2 with energy-rich substrates, such as epoxides and aziridines, to generate polycarbonates/polycarbamates and/or cyclic carbonates/carbamates has drawn significant attention over the past decades. Consequently, most of the known studies used highly reactive substrates and/or severe reaction conditions to activate CO 2, limiting the application of such methods. However, activation and utilization of CO 2 is still problematic due to the fact that it is the most oxidized form of carbon, which is also thermodynamically stable and/or kinetically inert in certain desired transformations. As a result, valorization of CO 2 is currently receiving considerable and ever increasing attention by the scientific community 2, 3, 4. Although the extensive use of carbon dioxide for chemical production cannot solve this problem alone, CO 2 is a useful one-carbon (C1) building block in organic synthesis due to its abundance, availability, nontoxicity and recyclability. Obviously, there is an urgent need to control CO 2 emissions and develop efficient carbon capture systems. This increase in CO 2 concentration is largely due to the combustion of fossil fuels, which are required to meet the world’s energy demand 1. Since pre-industrial times, the amount of CO 2 has steadily increased and nowadays CO 2 is a component of greenhouse gases, which are primarily responsible for the rise in atmospheric temperature and probably abnormal changes in the global climate. In addition to biomass, CO 2 offers the possibility to create a renewable carbon economy. Until now, the vast majority of carbon resources are based on crude oil, natural gas and coal. However, when dealing with the feedstock of the chemical industry, the level of sustainability is still far from satisfactory. A more sensible resource management is the prerequisite for the sustainable development of future generations. ![]() ![]() ![]() ![]() Sunset Strip, the section between Havenhurst Drive and Doheny Drive, has a chequered history-it was the setting for counterculture protests in the 1960s, rock and roll decadence in the ‘70s and ‘80s, and has more recently undergone a chic renaissance, with luxury hotel towers and fine restaurants hidden behind ivy-covered walls.

The shades that have more pigmentation and may be better suited to deep skin tones, are Bali, Caribbean, and Maldives. Most of them are quite sheer, but the formula is buildable.

If you click the link after “where to buy” above, that will take you to the Putty Blush page which includes a photo of every shade swatched on light, medium, and dark skin tones. However, after seeing swatches for all eight shades, I think there are options for every skin tone. This blush is quite sheer in the shade that I have, Tahiti (swatched in this photo this is about three layers to show the color built up), so I was originally concerned that the Putty Blushes might not work for all skin tones.

If this article leaves you feeling creative, then you should check out the 10 Easiest Musical Instruments To Make At Homeas well.īrace yourself for a brief journey into the world of wild creativity and wonder with this list of 11 unusual musical instruments with weird names. We did not rank our list, since we could not come up with a method of ranking weirdness so to speak, so we just listed the instruments we found to be weird. We eventually found what we have been looking for, and we are ready to share our findings with you. There were a lot of really unusual instruments listed there, but we knew we were looking for instruments that had to fit the bill perfectly, meaning it had to have a weird name and also weird way of operation to match. Websites like Cmuse, Mental Floss, Phrontistery and Odd Music spend their time too looking for unusual instruments. Thankfully, we did find quite a few remarkable websites that are dedicated to such musical instruments. To come up with such a list we had to do a lot of digging. As you can imagine, it is basically as the name says twelve guitars morphed into one awesome guitar with 12 necks. A few musical instruments that have every right to be on the list, but did not make it due to their names not being that weird, are the Chapman stick, a guitar like instrument that is used to play bass lines, melody lines, chords, or textures, and also the 12 neck guitar, the creation of Japanese artist Yoshihiko Satoh. We’ll definitely elaborate some more on our list, with this one. Or take a look at the hydraulophone , a musical instrument where music is produced by contact between jets of water and the player’s fingers. The sound of bowing strings comes out of a metallic horn instead of the wooden body of the cello. Take the cello-horn, for example, the name is self-explanatory as it’s an instrument that combines the cello and a horn in one. The thing is any musical instruments you come across are going to be cool musical instruments in their own way. You will find classes to learn these instruments, however the instruments that made our list are so unique that you might not find a class where you can actually learn to play them. ![]() If you are looking for unusual instruments to learn, which is a great way to stand out from the crowd, then you should try the bagpipe, the hang drum or even Bassoon. However, these instruments pale in comparison to what we are talking about on this list. We also have The ektara a single bowstring folk instrument used primarily by wandering bards in India and Bangladesh. There are lots of uncommon musical instruments such as the Balalaika a stringed instrument from medieval Russia that basically looks like an oddly shaped guitar. On the contrary, the musical instruments that made our list are really very cool and you just might end up developing a sense of appreciation for these oddities yourself. Of course, if something is weird it does not make it bad, as you will find out in our list. As you can gather from the title of this article, we will be delving into the realm of sheer weirdness. ![]() ![]() Once we have added it, we go to the Search option and enter “Popcorn time”.Popcorn Time Download 4 on 265 votes Watch torrent movies instantly.

"We’re constantly working with missing information about how humans are operating and we very intuitively fill in the gaps.".Hidden information and intentions abound in daily life, even in seemingly simple tasks like helping a partner load the dishwasher or driving a car through a street alongside other drivers.But in the real world, an AI system might see a human do something it's never seen before - and have to reason the goal of the person through common sense.Yes, but: A board game is a "highly controlled and limited setting," says Luca Weihs, a research scientist at the Allen Institute for AI who works on how systems can be physically embodied to control a robot or vehicle. "When it comes to planning against adversaries, games are not only important they are necessary," he says, adding they can provide insights about negotiating and reasoning for business, finance and defense sectors, which the two companies he founded and runs, Strategy Robot and Strategic Machines, focus on.The debate is "a misguided question," says Tuomas Sandholm, a professor at Carnegie Mellon University who has studied game theory for three decades. But others say some of the skills required to win games of strategy could lead to real-world applications. ![]()

Only administrators will have access to the server, whereas normal public requests will be turned away until maintenance is complete. That is why a once normally-functional page will display a 503 Service Unavailable Error, alongside a message about the server being down for maintenance. The server has not actually crashed or shut down but is in a mode of service that prevents requests from behaving as normal. The Server is Down for MaintenanceĪ 503 Error should pop up if the server is down for maintenance. This is usually due to the server being "down" for scheduled maintenance or due to a heavy traffic load that prevents it from properly serving all incoming requests. Diagnosing a 503 Service Unavailable ErrorĪs mentioned before, a 503 Error indicates that the server (typically the actual web server on which your application is running) is temporarily unavailable. If you have the capability, create a complete copy of the application onto a secondary staging server that isn't "live." This will give you a clean testing ground to test all potential fixes to resolve the issue without threatening the security or sanctity of your live application. Otherwise, you might find yourself with additional errors and latent errors. Start With a Thorough Application Backupīefore attempting any fixes or changes to the system, perform a full backup of your application, database, and so forth. In the next section, we'll go over how to diagnose and fix this error. That's the 503 Service Unavailable Error in a nutshell. The problem will be something on the server-side, which performs most of the logic and processing for the app. If a 503 Service Unavailable Error occurs on a smartphone app, the issue will lie outside of the installed app. Normal web applications will often power smartphone apps that have a modern-looking user interface. This doesn't apply solely to websites, either. That means you can ignore most client-side code and components, such as HTML, cascading style sheets (CSS), client-side JavaScript, etc. Since a 503 Error means something is wrong with the server of your application, you can disregard the client side of things. ![]() This value should either be a Date value indicating the timestamp the service will be available, or a numeric value indicating how many seconds from now the user agent must wait to retry. This header should inform the user agent (client) how long it should wait to attempt the request again. Additionally, the application should send a Response-After HTTP header. In most cases, the web server should provide a user-friendly page showing that the service is temporarily unavailable. Furthermore, unlike gateway-related 5xx response codes that indicate issues either on the web server or another server further upstream, the 503 Error code indicates an issue on the actual web server hosting your application. Unlike the 502 Bad Gateway Error, which indicates that a server somewhere in the connection chain is down or unavailable a 503 Service Unavailable Error indicates that the server is temporarily unable to handle the request but is otherwise functioning as normal. The Problem is Server-SideĪll HTTP response status codes that are in the 5xx category are server error responses. By the end of this article, you'll know what a 503 Service Unavailable Error is and how to troubleshoot and fix it. That's why, in this article, we'll examine the 503 Service Unavailable Error in-depth. As you can imagine, determining the cause of a particular status code can be challenging. There are dozens of possible HTTP status codes used to represent the complex relationship between the client, a web application, a web server, and multiple third-party web services. While a 500 Internal Server Error indicates an issue preventing the server from handling the request entirely, a 503 Service Unavailable Error indicates that the server is still functioning properly and can process the request, but has opted to return the 503 response code. This may be due to an overloaded server or a server that's down for maintenance. This particular response code differs from the 500 Internal Server Error we explored some time ago. A 503 Service Unavailable Error is an HTTP response status code indicating that a server is temporarily unable to handle the request. ![]() |
