This command configures the distribution to install all drivers by default. The most general configuration command looks like this, with no arguments following the config argument. Go in distribution directory dbi-0.2.0 nd configure it using the setup.rb script in that directory. Now, follow the steps given below − Step 1 You can install ruby DBI using the Ruby Gems packaging manager:īefore starting this installation make sure you have the root privilege. This module acts as a DBD as explained above and can be downloaded from Obtaining and Installing Ruby/DBI If you want to write Ruby scripts to access MySQL databases, you'll need to have the Ruby MySQL module installed. Each driver interprets requests from the DBI layer and maps them onto requests appropriate for a given type of database server. There is one driver for MySQL, another for PostgreSQL, another for InterBase, another for Oracle, and so forth. This layer is database dependent different drivers provide access to different database engines. This layer is database independent and provides a set of common access methods that are used the same way regardless of the type of database server with which you're communicating. The general architecture for Ruby DBI uses two layers − This is clear from the following architecture diagram. You can use DBI whether you are working with Oracle, MySQL or Informix, etc. It defines a set of methods, variables, and conventions that provide a consistent database interface, independent of the actual database being used.ĭBI is independent of any database available in the backend. The Ruby DBI module provides a database-independent interface for Ruby scripts similar to that of the Perl DBI module.ĭBI stands for Database Independent Interface for Ruby, which means DBI provides an abstraction layer between the Ruby code and the underlying database, allowing you to switch database implementations really easily. This chapter teaches you how to access a database using Ruby.

This fact was only known to corporate executives who shared the belief that their principle objective was the funding of the Wesker Project. Umbrella's true goal was not, in fact, a capitalistic urge for monopolization of a lucrative industry. Their tourism firm, the Paraguas Line Company, earned revenue from transporting passengers across the Atlantic as a front for the transporting viral weapon samples from West Africa. Umbrella had a number of other subsidiaries that included Umbrella Medical Equipment, as well as Umbrella Industries which was responsible for the development of anti- B.O.W. Umbrella Pharmaceuticals was able to cover their true intentions by researching vaccines for the same viruses as a front. Soon after the opening of its pharmaceutical subsidiary, Umbrella Pharmaceuticals, Umbrella began developing biological weaponry for militaries across the world as part of a worldwide conspiracy to accumulate deadly viruses directly prohibited by the 1972 Biological Weapons Convention. Umbrella's large array of subsidiaries was typical for large-scale corporations, though it was purposely built to cover up illegal activities. Umbrella had influence in the production and sale of cosmetics, chemicals, pharmaceuticals, industrial machine production, consumer products, health foods, the transportation industry and tourism. The Umbrella Corporation was a multinational conglomerate with subsidiaries active in a variety of industries from the 1980s to the early 2000s. For private military company, see Blue Umbrella.

Great for the ketogenic diet because it’s high in fats.It all depends on what you’re looking for when it comes to a diet. Pros and Cons of Bulletproof Coffeeīulletproof coffee has some benefits, as well as some downsides. People who drink bulletproof coffee often are doing so because it replaces other meals and offers a boost of energy. Originally, bulletproof coffee (also sometimes called butter coffee) started trending years ago among people who were into the paleo diet lifestyle.Īccording to the recipe, bulletproof coffee is a cup of brewed coffee mixed with grass-fed butter and MCT oil.īulletproof coffee has also been popular among people who follow the keto diet because of its high-fat content. What Is Bulletproof Coffee?īulletproof coffee is a high-calorie coffee drink that was intended as a replacement for a breakfast meal. Whether you’re new to intermittent fasting or have been at it for a while, DoFasting is an amazing app to help people along their weight loss journey. We recommend DoFasting, which helps you design your own special fasting schedule.ĭoFasting also has plenty of recipes, tips, and tricks to make it through your fasting period without breaking your fast. If you’re looking for more ways to enjoy your fasting period without giving up on the hunger pangs, you might benefit from a fasting app. Technically, butter coffee does indeed break your fast but causes much less disruption than something high in carbohydrates. This is much lower than the recommended 500 calories or less when it comes to intermittent fasting. It was originally made to be a complete meal replacement, which means it needs to feed your body energy.īulletproof coffee has about 230 calories. Unlike plain black coffee, bulletproof coffee is high in calories. For others, it means having reduced calories.įor intermittent fasting, bulletproof coffee is probably one of the last drinks you want to have. For some people, their fasting window means that they have as few calories as possible. Whether or not bulletproof coffee entirely breaks a fast depends on how you’re fasting. (i) Your answer for part (h) should be three times as large as the answer for part (g). What is the average force the molecule exerts on one of the walls of the container? (Assume that the molecule’s velocity is perpendicular to the two sides that it strikes.) (f) What is the average force per unit area? (g) How many oxygen molecules traveling at this speed are necessary to produce an average pressure of 1 atm? (h) Compute the number of oxygen molecules that are contained in a vessel of this size at 300 K and atmospheric pressure. What is (a) the average translational kinetic energy of an oxygen molecule at a temperature of 300 K (b) the average value of the square of its speed (c) the root-mean-square speed (d) the momentum of an oxygen molecule traveling at this speed? (e) Suppose an oxygen molecule traveling at this speed bounces back and forth between opposite sides of a cubical vessel 0.10 m on a side. This molar mass calculator allows you to double check if you’re getting the right answer.Oxygen ( O 2 O_ O 2 ) has a molar mass of 32.0 g/mol. Let us try to calculate and see how it goes. 1 mole of oxygen 6.022 × 10 23 number of oxygen molecules. Molar mass: The mass of one mole of oxygen. So the mass of one molecule of oxygen will be 2 × 16 u 32 u. Finally, add the products together and you’ll arrive at the answer.Īfter reading and working through these three examples, you should be able to calculate the molar mass of anything. of one O X 2 molecule (the whole O O entity). Next, multiply the number of a particular element by its molar mass. In this compound, there 2N, 8H, 1C, and 3O. Start by determining how many of each elements there are. The only difference is you’ll need to multiply the subscript on the outside of the parenthesis by the subscripts inside the parenthesis. 3 mol O2 Molar mass of KClO3 122.55 g / mol Molar mass of O2 32 g / mol 0.384 g loss 0.384 g 02 produced 0.384 So, produced 02 0.012. The process is very similar to calculating the molar mass of a simple compound. Finally, add the products together and you’ll arrive at the answer. In this compound, there are 1 C, 4 H (3+1), and 1 O. Start by determining how many of each elements there are by looking the subscripts (small number next to the element symbol). All you need to do is find the atomic mass of the element on the periodic table and report the number with the unit grams per mole or g/mol.įrom this, you can see that sodium’s molar mass will be 22.99 g/mol. We can’t determine the mass of this immediately. Formula: The relative atomic mass indicates how many times larger the mass of a given atom is than 1/12 the mass of the 12 C carbon isotope. Answer (1 of 4): Step by step answer: You said that we’re working with 3.011024 molecules of oxygen gas. Fe4Fe(CN)63, NaHCO3, ch3coonh4, h2so4, pb(c2h3o2)23h2o, caso41/2h2o) and press Enter or click Calculate button. By the end of this post, you’ll be able to calculate the molar mass of anything.įinding the molar mass of a single element is really simple. Enter a chemical formula to calculate its molar mass (e.g. We’ll go through three examples progressing from easy to “difficult”. Intensive: pressure p, temperature T, density g, mole fraction a (O2), molar concentration c(N2). How to calculate molar mass with examples That substance can be an element or a compound. Simply said, molar mass is how much one mole of a substance weighs. Lets start by talking what the term means. The Philadelphia Case Company was know for the finest of pocket watch cases and this is an excellent example. This antique Waltham Royal Pocket Watch is in excellent condition at 97 years old a beautiful and collectable timepiece sure to not disappoint. Then we have raised gold jewel settings, a gold center wheel, gold balance wheel and weights with a high-grade micro regulator, all of added accuracy. This Hunter Case Royal 17 jewel movement is stem set and stem wound. The total number produced was 123,900 in total from 1877 through 1923 an impressive lifespan. Royal was a very popular Waltham offering, a mainstay in the Waltham line up of fine pocket watches. This American Waltham 17 Jewel Royal Movement has pristine antique damasked nickel silver plates without reckless jewelers or corrosion. Hopefully the many pictures and extreme magnification help in the description of this truly fine Waltham Hunter Case Pocket Watch. Many of these gold or gold fill cases with their steel spring latches did not hold up over the last 100 plus years, this is an excellent example of a fine Philadelphia Triple Hinge Hunter Case. These fine Hunter Case Pocket Watches are getting harder to locate in this fine condition. The Royal Movement is housed in this fine Philadelphia Case Company Hunter Case this is a size 12 and measures 1¾ inch in diameter. The high grade Royal is more common in an Open Face configuration and rare in this Hunter Case configuration winding at the 3:00 position. We have a 17 Jewel Royal Movement, the Gentlemen’s Dress Pocket Watch housed in a classic Hunter Case configuration. Folks we have a special offering for your consideration this American Waltham Pocket Watch. While it's not a huge problem, many newer photo-editing apps let you see effects and virtual lenses in real time, then let you edit further once the picture is taken if you want. One thing Camera+ doesn't have is the ability to see live previews of effects before you take your picture, which is common among other apps in the genre. Adding The Lab in a recent version was a huge update to Camera+, and with this latest update adding pro-quality photos, it shows that the developers are not running out of steam on this four-year-old app. ConclusionĬamera+ might be one of the oldest photo editors in the App Store, but the reason it stays popular is because its developers continue to listen to users and add more and more tools that will help you take great photos. In other words, the photo looks great, but if you take too many of these pro-quality photos, you're going to burn through all your storage capacity pretty quickly. Having received support from CamFi manufacturer, I can finally operate my CamFi Pro Plus on my camera, mobile & laptop. What makes this camera setup even more awesome is that this camera lens is combined with the wide aperture of F/1. The Oppo Reno8 Pro+ main Camera is 50 megapixel Sony IMX 766 F/1.9. But when I took almost the exact same photo using Camera+ on pro quality, the file size was almost 10MB. Oppo Reno 8 Pro Plus has 3 cameras at the back and the main camera is awesome. The "Actual size" or largest exportable file size from the iPhone camera came in at 1.8MB. For reference, I took a regular photo using the iPhone camera app at my desk of some colorful superhero figurines. The only issue I came across is that it can take a couple of seconds to save photos/videos, but that's standard for 3rd party photography apps. While testing it, I found every feature works as advertised. In my testing I can agree it takes great-looking pictures, but here's why you'll only want to do it for special photos: the lossless files take up a lot of space. Camera Plus Pro is packed with features and its unassuming interface makes taking pictures a joy. The play area expands outwards as you lay more and more cards out, to form your ‘Province’. The cards of your province will be laid on the table as the game progresses, and cards are rotated anti-clockwise to increase resources with favourable dice rolls, and clockwise to reduce resources when spending/trading. Option 3: Play The Separate 2 Player Catan Game: Rivals For CatanĪ whole different game in it’s own right, it retains a few (and I mean…not a lot) of the mechanisms from the original game, but essentially this is a different beast.Īllocating resources, dice rolling etc are all there in the normal way, but there is no board, and only cards instead. The official version can be found here and there’s a nice explanation of this version of the rules here if you prefer video format: The additional chips can be used in various functions and extends the trading capacity of the game. Neutral building means that each time you build out a road or settlement, one of the 2 dummy players receives that same building also. This version adds extra (not included) chips into the game to help retain the trading element – crucial to the base game’s variety.Ĭrucially, on each turn, a player uses 2 separate rolls of 2 dice, instead of one roll. Option 2: Official 2 Player Variant Settlers Of Catan Rules: Here’s Nick’s original pdf to refer to: (Opens in New Window) Whilst it can seem a bit finnicky to set up, this version actually works surprisingly well, – One of each tile type is removed from the game – Remaining lettered hexes are then laid out in a specific sequence and order – 6 harbour tiles are used as a maximum – Certain starting tiles are discarded and the robber does not enter play until a 7 is rolled – Specific resources and cards are removed from play before beginning – Play up to 10 victory points as normal Nick Borko came up with a 2 player variant rule set that many report success with: Option 1: House Rules for 2 player Settlers Of Catan Out of the box, Settlers of Catan is intended for 3-6 players.īut, there’s a few options available if you’re looking to play Catan with just 2 players.Īmong the several more obscure variations, my research pulled up these 3 as the most popular: If we do not have the necessary resources, we can acquire them by trading with our opponents.Įach settlement is worth 1 victory point and each city is worth 2 victory points.As a single Dad gamer with daughter, over the years it’s been important for us to track down the very best 2 player board game options. For example, a road costs 1 brick and 1 lumber. We use these resources to expand across Catan: we build roads and new settlements, or we upgrade our existing settlements to cities. Hills produce brick, forests produce lumber, mountains produce ore, fields produce grain, and pastures produce wool. Each player who owns a settlement adjacent to a terrain hex marked with the number rolled receives a resource produced by this hex. An “11”! Each terrain hex is marked with a die roll number. They are our starting settlements.Īnd so it begins. Catan is born - a beautiful island with mountains, pastures, hills, fields, and forests, surrounded by the sea.Įach of us places two small houses on spaces where three terrain hexes meet. To begin the game, we build the game board using hexagonal terrain tiles. Proceed strategically! If you found your settlements in the right places and skillfully trade your resources, then the odds will be in your favor. Ore for wool, brick for lumber - you trade according to what is needed for your current building projects. Some resources you have in abundance, other resources are scarce. Will you succeed in gaining supremacy on Catan? Barter trade dominates the scene. You build roads and new settlements that eventually become cities. Fortunately, the land is rich in natural resources. The women and men of your expedition build the first two settlements. |
