Cascade delete postgres9/28/2023 ![]() There is a warning in the documentation that 'refresh-expire' changes the default behavior and also 'expunge' changes the default behavior. This means we can also write: cascade='all'īut wait, 'all' includes also 'refresh-expire' and 'expunge'. This is very confusing because 'delete' is already part of 'all'. In the example the Cascade Delete line is: cascade='all, delete' The SQLAlchemy documentation then gives an example of Cascade Delete: When the parent is deleted, its children also must be deleted. To keep default behavior, you must add 'save-update' and 'merge' to the 'cascade'-option. This implies that if you were not using the 'cascade'-option and want to add to a 'cascade'-option to a relationship, you are changing (!) the default behavior. The 'cascade'-option has a default value. SQLAlchemy Cascade DeletesĬascade Deletes in SQLAlchemy can be specified in a relationship using the 'cascade'-option. The only way to make sure that we are doing the right thing is to read the documentation, read the documentation again, and create some examples that confirm that we understood. Huh? What? And then after some time: WTF! Help! But I want only recipes!īut there are no recipes. The 'all' symbol is a synonym for 'save-update, merge', 'refresh-expire', 'expunge', 'delete', and using it in conjunction with 'delete-orphan' indicates that the child object should follow along with its parent in all cases, and be deleted once it is no longer associated with that parent. The typical alternative setting for this parameter is either all or more commonly 'all, delete-orphan'. The default value of the relationship 'cascade'-option is 'save-update, merge'.

U.s nuclear submarine9/28/2023 ![]() Marine-type reactors differ from land-based commercial electric power reactors in several respects. and Soviet navies have designed warships powered with liquid metal cooled reactors. The majority of marine reactors are of the pressurized water type, although the U.S. Most American aircraft carriers are powered by two reactors, but USS Enterprise had eight. Some nuclear submarines have a single reactor, but Russian submarines have two, and so had USS Triton. and British navies rely on direct steam turbine propulsion, while French and Chinese ships use the turbine to generate electricity for propulsion ( turbo-electric transmission). In another form of drive system, the turbine turns an electrical generator, and the electric power produced is fed to one or more drive motors for the vessel's propellers. The output shaft of the turbine may be connected to a gearbox to reduce rotation speed, then a shaft connects to the vessel's propellers. There may be many stages of rotating blades and fixed guide vanes. In the turbine, the steam expands and reduces its pressure as it imparts energy to the rotating blades of the turbine. Any water lost in the process can be made up by desalinated sea water added to the steam generator feed water. ![]() The water is pumped back to the steam generator and continues the cycle. Spent steam at low pressure runs through a condenser cooled by seawater and returns to liquid form. That water is converted to steam and passes through steam driers on its way to the steam turbine. The hot water from the reactor heats a separate water circuit in the steam generator. Water is circulated by pumps at lower power levels, reactors designed for submarines may rely on natural circulation of the water to reduce noise generated by the pumps. Any radioactive contamination in the primary water is confined. This circuit operates at a temperature of around 250 to 300 ☌ (482 to 572 ☏). A primary water circuit transfers heat generated from nuclear fission in the fuel to a steam generator this water is kept under pressure so it does not boil. Most naval nuclear reactors are of the pressurized water type, with the exception of a few attempts at using liquid sodium-cooled reactors. ![]() Power plants Basic operation of naval ship or submarine The low fuel cost is offset by high operating costs and investment in infrastructure however, so nearly all nuclear-powered vessels are military. ![]() All the fuel is contained within the nuclear reactor, so no cargo or supplies space is taken up by fuel, nor is space taken up by exhaust stacks or combustion air intakes. Ĭompared to oil- or coal-fuelled ships, nuclear propulsion offers the advantage of very long intervals of operation before refueling. A small number of experimental civil nuclear ships have been built. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. Propulsion system for marine vessels utilizing a nuclear powerplant When the nuclear-powered Arktika class 50 Let Pobedy was put into service in 2007, it became the world's largest icebreaker.

Size: 1.4g| Type: Stick| Number of colors: 11| Shimmer: In some shades While the range of colors is unique (in addition to classic browns and taupes, there’s an olive green, sapphire blue, and warm cranberry), we’d still like to see more options, including grays and purples. You can choose from eleven shades in either matte or shimmer finishes the shimmers have a luminosity to them rather than a harsh sparkle, so they just enhance the eye rather than drawing attention to any texture. It’s infused with hydrating and nourishing ingredients, like sodium hyaluronate, aloe leaf extract, and ceramides to keep mature lids feeling comfortable.Įvery shade can be worn concentrated or buffed out, which is easy to do - you can either use your finger or the generously-sized sponge tip at the base of the packaging (there’s a sharpener hidden in there, too). Though many durable formulas, especially creams, can feel drying on the lids, this one doesn’t. The shadow stick features rich pigment that is both waterproof and smudge-proof once it sets. While the brand’s “liquid lash extensions” mascara may get all the hype, this longwearing cream shadow is what should be getting more credit. We love the shade options, but we wish there were more! You also can’t go wrong with Pat McGrath Labs Mothership X: Moonlit Seduction, which offers a complimentary shade for every eye color and skin tone, plus a few bold, playful shades for a night out. Our Best Overall pick is from Thrive Causemetics for its water- and smudge-proof formula so the rich pigment stays in place all day, and easy-to-use stick design. It can build up in creases, smudge more easily and, depending on the finish of the formula, call attention to crepey lids.īut that’s not to say you have to give up on eyeshadow altogether! By simply purchasing certain product types, selecting specific shades, and following recommended application techniques, you can enhance your eyes beautifully. That’s because as fine lines, wrinkles, folds, and other textural changes to the skin start to form, they change how eyeshadow “sits” on the lid. When shopping for eyeshadow for older women, there are a lot of different factors to consider that may never have mattered before. In many cases, these frustrating changes to your go-to eye look are caused by getting older. But when eyeshadow starts to look like musty drapes rather than a luxurious curtain, it’s time to switch things up. We like to think of eye makeup as the really lovely window dressing. ![]() ![]() You’ve heard the old adage - the eyes are the windows to the soul. There may be many code chunks, so they can help you organize your R code into parts, perhaps interspersed with text. This is where you may load packages, import data, and perform the actual data management and visualisation. Sections of the script that are dedicated to running R code are called “chunks”. For more details, see the handbook pages on R on network drives and. ![]() If you use Git (much recommended!), this will be familiar. Note that use of setwd() in R Markdown scripts is not recommended – it only applies to the code chunk that it is written in.īecause R Markdown can run into pandoc issues when running on a shared network drive, it is recommended that your folder is on your local machine, e.g. in a project within ‘My Documents’. For instance, to import a file called “data.csv” from within the projectX folder, the code would be import(here(“data.csv”)). The here package sets the working directory to the root folder of the R project and is explained in detail in the R projects and Import and export pages of this handbook. To refer to files elsewhere, you will either need to use the full file path or use the here package. For instance, if the R project is within ~/Documents/projectX and the Rmd file itself is in a subfolder ~/Documents/projectX/markdownfiles/markdown.Rmd, the code read.csv(“data.csv”) within the markdown will look for a csv file in the markdownfiles folder, and not the root project folder where scripts within projects would normally automatically look. The working directory of a markdown file is wherever the Rmd file itself is saved. md file is then processed by pandoc to create the finished product: a Microsoft Word document, HTML file, powerpoint document, pdf, etc. md (markdown) file which includes the R code and its rendered output.

Social thinking whole body listening9/27/2023 ![]() View all the webinars in the 10 Concepts series within our larger webinar library. We recommend learning about (and teaching) the concepts in order as they build on one another. Each concept should be taught slowly for one month or longer-it takes time for students to deeply understand the ideas and begin using them in their lives. Strengthen your students’ social-emotional learning by infusing your teaching with these concepts over the course of the school year. This webinar is part of a series that shares best practices for teaching 10 core concepts from the Social Thinking Methodology. Then, tune in to the next webinar to learn how to build on this concept with best practices for teaching whole body listening! How do you know if your body is in the group? Join Social Thinking’s founder, Michelle Garcia Winner, as she deconstructs this seemingly simple concept and exposes the many things we consider when getting-and keeping-our bodies in a group.Īfter watching this webinar, infuse your teaching with the concept over the next month to help your students understand it deeply and meaningfully (avoid memorization). Where your body is relative to the group matters-it influences how others perceive you and your intentions, and ultimately their relationship with you.
