Aluminum charge1/30/2024 ![]() Isotopes are simply different variants of the prime element’s atoms, differing only in the number of neutrons possessed by the atom. The number of neutrons that an element has defines the isotopes of that element. If an atom of an element is neutral, that means it has the same number of electrons and protons. The atomic number of an element is based upon the number of protons an atom of that element has. These electron shells hold electrons in orbit and an atom can have multiple electron shells.Ītoms have different properties based on how the simple constituent particles are arranged. The outermost portions of the atom are referred to as the electron shells. Outside of the nucleus is the orbital region, consisting of electrons that orbit the nucleus. The nucleus is comprised of neutrons and protons. The first region of the atom is the nucleus, the center of the atom. Neutrons weigh around 1.67 x 10 -24 grams. Neutrons and protons have masses that are approximately equal. Protons are positively charged subatomic particles, while neutrons are subatomic particles that have no charge. Neutrons, electrons, and protons are the three constituent parts of an atom. The Structure Of An AtomĪtoms are made out of three basic parts, separated into two distinct regions. Aluminum is used for a wide variety of different purposes, including the creation of vehicles, batteries and packaging materials, as well as the construction of buildings and the creation of cooking utensils. In the year 2016, the global production of aluminum was around 59 million metric tons. Along with iron, aluminum is the most commonly used metal. Aluminum is an extremely abundant element, in fact, it is the most abundant metal element in the crust of the earth. It is represented with the symbol “Al” and it has the atomic number 13. O’RourkeĪluminum is a soft metal in the boron group on the periodic table of elements. Consider that 75% of all the aluminum made since 1886 is still in use.” - William J. “Aluminum has been called the sustainability nutrient of the world, and for good reason. Yet to better understand the relationship between ions, ionization, and the different elements, a closer look at both positive and negative ions is needed. That’s the quick answer regarding how aluminum’s charge is 3+. Aluminum then has three excess protons so the charge of a base aluminum ion is 3+. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons. This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The charge of an aluminum ion is typically 3+. History and Uses: Although aluminum is the most abundant. Say what? Aluminum is pronounced as ah-LOO-men-em. What's in a name? From the Latin word for alum, alumen. Stanford University scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting and inexpensive. Ultra-fast charging aluminum battery offers safe.Bendable aluminum-ion batteries could replace the lithium-ion batteries currently in our devices, and be both longer-lasting and cheaper.New Aluminum Battery Takes Just 60 Seconds To.This may look like a scrap of kitchen foil, but it’s actually a new kind of aluminum battery that could out-perform the lithium-ion cells in your smartphone. ![]() This Super-Stable Aluminum Battery Can Charge in.It is the most commonly occurring of several aluminium oxides, and.

The WOW speed test at uses several factors to rate the network connection, such as download test, Wi-Fi speed test, upload test, latency test, ping test, and jitter test. So, you would know whether or not your broadband service provider is worth it. This tool weighs your internet on several metrics and provides you the impartial result for broadband speed test performed over WOW or any other broadband service provider.

When does spring start1/29/2024 We see the evidence of this and measure it in the form of animal life cycles, pollen, flowers, buds and grass growth, not to mention current weather patterns too. the other 8 months are a long drawn out spring and autumn. The astronomical spring will then last until the. ![]() So, whichever method you’re using, spring is officially here. Mother Nature - The reality is that New Zealand really does have a shorter 2 month summer and a shorter 2 month winter in .nz's view. In 2023, the spring (also known as vernal) equinox falls today, Monday, March 20.Solar Winter (The 3 months/12 weeks of the year with the least amount of available sunlight with the shortest day of the year in the middle, meaning the Solar Winter runs from early May to early August - so the 'solar spring' kicked off in early August.This is done for record keeping as a tidy date to start from and often co-incides with the seasonal changes too. Meteorological Dates (winter starts on June 1, spring starts Sept 1, summer starts Dec 1, etc).A number of plants don't trigger spring growth until the equinox, as that is when daylight hours start to become longer than the hours of darkness. This date is based on the earth's angle and rotation around the sun and not the weather. Astronomical Dates (winter starts on the shortest day, around June 21, spring therefore doesn't start until the equinox around Sept 21 (this year the date is Sept 23, it can move +/- a couple days each year).When does Winter End and Spring Start? It all depends on what your definition of 'winter' is. ![]() "However, there are really four different start dates to Spring - and you can take your pick as to which one you prefer to go by as none of them are a perfect guide," says the weather organisation. "MetService and NIWA talk about both the Astronomical and Meteorological dates to the seasons. 24: Census day: Last day to drop without a W Feb. Then the clocks ‘spring forward’ as we welcome the sunnier days of Spring and Summer. 17: End of late registration and last day to add/swap: Jan. ![]() The Ministry of Internal Affairs confirmed to us several years ago that the Government has no official preference on when the seasons change. Daylight Savings will start at 1am on Sunday, March 26 in 2023. When it comes to the end of Winter and the start of Spring, New Zealanders have the choice of four dates and none are official, says .nz Diy bud trimmer plans1/29/2024 “There were rumblings throughout the industry about a flower price crash in June,” says Metzler. Farmers-many still desperate to sell last year’s flower-have been selling even their best buds to processors for distillation, which is normally where only the less valuable biomass gets funneled. There’s been a steady price drop for flower the past few months, because of oversupply. “We were lucky-that was right before the crash.” “Prior to harvest, we signed an output contract with a processor for our biomass,” Metzler says. Generally, they would prune all the way to the ground, but this year Metzler presold the farm’s leftover biomass to a processor for extraction of oils and distillates. Standing on either side of 5-foot bushy cannabis plants-each holding pruning shears-they trim the stalks. While grinding up flowers makes them easier to work with for cooking or small-scale extractions, it’s not necessary for getting a high yield, as long as you get it all in contact with the solvent.Pickers double up for each plant. The presence of THC mostly on the outside of the plant is great news, but no surprise butane extractions on unadulterated bud work spectacularly well because of this fact. Inside these vesicles there is some THC, but also high amounts of terpenoids, which are less viscous. Resinous THC also accumulates in the fibrillar matrices (pardon the jargon) of the secretory vesicles. The essential oils, including THC, mostly accumulate on the outer layer of the gland head, but also on the outer layer of the epidermal cells that cover the entire bract, or any trichome-dense area. ![]() The cuticle, thickens getting richer and richer in oil as flowering progresses. The theory is that these precursors get transported to the secretory vesicles above, and are converted into cannabinoids and terpenoids once they’re there.Īs the gland head churns out its product, the resin gets deposited, and up close to the cuticle, the outer layers of trichome surface. Secretory cells take the nutrients from the phloem and turn them into precursors for cannabinoid and terpenoid metabolism. As the flower matures, and as mature flowers dry, this connection weakens and gland heads tend to fall off.Īt the base of the gland head are stipe cells, which hold up the secretory cells. The basal cell at the top of the stalk holds on to the gland head. The hypodermal cells on the inside of the stalk constantly transport nutrients ( ) to the gland head. The epidermal cells hold up the mature trichome forming the outside of the stalk, and a continuous layer extends over the entire bract surface. ![]() ![]() Zoom in close enough and you can see the individual cells that make up the structure.Ĭapitate stalked trichomes have two main parts: the stalk and the gland head. Looking closely, you’ll see six different types of these glands are all oozing resin during flowering, but the biggest ones with the most juice are the capitate stalked trichomes.Īt about 50 to 100 micrometers wide, trichomes are very small. A bract houses the seeds in a fertilized plant and has a high density of trichomes. Trichomes might grow off a leaf around the flower of a female plant, or a bract (pictured above). Scientists used to think that THC and other cannabinoids were made in the green plant tissue and transported out to the trichomes during flowering, but after intensive research, they realized that the trichomes themselves make the cannabinoids and terpenes. The trichomes cover all parts of the buds, from the interior stems to the surrounding leaves. Leaves have around 4%, while buds have up to 25% or 30% of dry weight. The different methods of hashmaking focus on isolating these sticky little parts of the cannabis plant because they house the majority of its resin.Įvery part of the cannabis plant has at least a little THC in it. Trichomes, those little tiny crystal-like hairs that cover the buds, hold all the good stuff. Alaska northern lights1/29/2024 ![]() Much of Canada’s Yukon territory extends into the Arctic Circle, which, alongside its low population densities and swathes of pristine wilderness, makes it one of the best places to see the aurora. And, some North American Inuit have tales that explain the lights as the spirits of their ancestors playing a ball game with a walrus skull. The Algonquin believed that the northern lights came from a fire made by their creator, Nanabozho. The lights have inspired legends in all the people who saw them regularly, including the indigenous people of the region. If your hotel doesn’t offer this service, I suggest you set your alarm to go off periodically throughout the night, to improve your chances of seeing them. Some hotels in Canada offer special wake-up calls or provide walkie-talkies so guests can alert each other in the event of a sighting. Not only are they unpredictable, they’re most easily seen during North America’s coldest months, blooming across the sky in the frigid hours between midnight and 3am. Seeing the lights requires a certain level of dedication and energy. Their form is also changeable, from rippling curtains or waving streamers to fast-moving dots, like a spotlight. They most often appear as a greenish-yellow, but you might also see blue, red and violet hues. The aurora borealis occurs when electrically charged particles from the solar wind collide with gaseous molecules in the Earth’s atmosphere. What are the northern lights? The northern lights A sighting is never assured, but here’s a guide to improving your chances. I spent an hour tucked under a warm duvet watching a celestial green glow creep up behind Cascade Mountain.įor me, the aurora borealis is one of the literal highlights of a trip to Canada or Alaska during the winter. I’d spent almost six months living in Banff trying to catch a glimpse, but it wasn’t until nearly the end of my first visit there that I lucked out. The first time I ever saw the northern lights was in the back of a pick-up truck, in Banff National Park. Best remote for flirc1/29/2024 It comes in two versions - a 16 GB version for $199/£199 and a 500GB version for $299/£299. Please let me know if you have any questions.The NVIDIA Shield Android TV is a high-powered Android TV device, featuring a Tegra X1 and 3GB of RAM (source). For only $19.95 on Amazon, I definitely think it is a good device at a good price with a lot of possibility. ![]() Instead of bringing them home and having life-less souvenirs, you can integrate them into Home Assistant using the Flirc! Conclusion Well the wand is actually just an infrared transmitter which is fired when the wand is flicked. To participate, you purchase (expensive) customized wands and can run around the hotel or tourist destination waving it at different objects. My family and I, specifically, encountered it at Great Wolf Lodge. It is an interactive live role playing game at many tourist attractions. Some of you may be familiar with MagiQuest. Set up the device in the same way and then you can integrate Home Assistant actions into your Harmony Hub Activity. If instead of an old remote you wanted to use the Harmony, you could simply set up some dummy device and make sure the the Harmony Hub or an IR mini blaster will have line of sight to the Flirc Receiver. As far as I know, the integration is one way, meaning that you can fire commands through the Harmony but Home Assistant cannot receive commands. Now, I happen to be a big fan of the Harmony Remote and its Home Assistant integration. So now I know that my remote’s “Netflix” button is mapped to keycode 50.Ī corresponding automation trigger would look like this: platform: eventĮvent_type: keyboard_remote_command_receivedĪnd from there it can do whatever you want- turn off lights, lock doors, turn on music, or even turn on your TV using your old remote! Logitech Harmony For example: Example of keyboard_remote_command_received response Listen for events from “keyboard_remote_command_received” and press the individual buttons. Go to the Developer Tools and then the Events tab. To do so, you need to obtain the “key_code” for each programmed button. Now you can make automations capable of anything your Home Assistant can do from the press of a button. Once you see it’s recognized, add the following to your configuration.yaml and restart: keyboard_remote: First, confirm it is recognized by Home Assistant by looking in the Supervisor’s Hardware tab. Now the Flirc can be set up in Home Assistant using the Keyboard Remote integration. ![]() Once you have recorded all the keys you want, you unplug the device from your computer and plug it into your Home Assistant box. You do not need to remember which buttons are mapped to which keys because they will later be identified in Home Assistant by watching the event log. Next, click on a key, and it will ask you to press the corresponding button on the remote. I think selecting a standard keyboard makes the most sense to maximize the number of programmable keys. There are a number of virtual keyboard or remotes you can select. So let’s walk through how this would be set up.įirst, download the software from the website and plug in the USB device. Except, instead of interacting by physically pressing keys, the key is “pressed” when it detects the corresponding infrared frequency. Those codes are saved on the device itself, so it can be moved to your Home Assistant Operating System box and will be seen as just an ordinary keyboard. The software lets you assign buttons to a virtual keyboard by selecting individual keys and firing your remote at it. First, you plug it into a PC, Mac, or Linux machine. ![]() The amazing thing about this device is its simplicity.

Effective nuclear charge1/29/2024 ![]() Note 3- Since “s” electrons are closer to the nucleus, screening effect or penetration effect follows the order s>p>d>f. Thus, the 4s electrons are first removed when d-block elements are ionized. Note 2- 3d electrons experience a much greater Z* than the 4s electron and would be held more tightly. Note 1- In hydrogen atom or H-like single electron species, the net pull on the electron is just exactly equal to the nuclear charge. Although lithium’s 2s electron spends most of its time in the outer lobe of that orbital feeling a nuclear charge of +1, it spends sometime inside the 1s orbital experiencing the full nuclear charge of +3. This can be understood by the fact that the 2s orbital has two maxima in its radial probability function vs radius graph, and the smaller maxima penetrates within the maximum of the inner 1s electron. However, lithium’s 2s electron experiences about 1.3 charge units. Thus, Z* felt by the 2s electron should be one rather than three. ![]() Example: Lithium(1s 22s 1)- The electron in the 2s orbital is shielded from the full attraction of the protons by the electrons of the 1s orbital. Z* = Z-σ where σ is screening or shielding constant. The effective nuclear charge( Z* or Zeff) is the net nuclear charge experienced by a given electron. The more shielding, the further the valence electron shell will spread out and the bigger atoms will become. Poor shielding of more diffused ”d” or “f’ orbitals explain phenomena such as the Lanthanide contraction and inert pair effect or anomalous change in size and IE down the group 13 or anomalous variation in size of 3d series elements. In an atom electrons are shielded from the pull of nucleus by the electrons of same shell and of inner shells. Shielding effect – The decrease in (lessening of)) attractive electrostatic charge from nuclear protons due to presence of electrons of same shell and of inner shells.
