As for New England, their win bumped their record up to 4-11. The Patriots also relied on Chad Ryland, whose 56-yard boot in the fourth quarter wound up being the difference in the game.īuffalo has been performing well recently as they've won four of their last five games, which provided a massive bump to their 9-6 record this season. Those 256 passing yards set a new season-high mark for him. The Patriots can attribute much of their success to Bailey Zappe, who threw for 256 yards and two touchdowns while completing 75.8% of his passes. It was close, but they ultimately received the gift of a 26-23 victory from a begrudging Patriotssquad. Meanwhile, New England gave up the first points last Sunday, but they didn't let that get them down. Ed Oliver was especially locked on to the Chargers' QB and sacked him twice. The Bills' defense stepped up as well, laying out the QB five times. Tyler Bass did the honors with a 29-yard field goal. The Bills were down by one with only five minutes and 26 seconds left when they drove 93 yards for the winning score. Those 130 receiving yards set a new season-high mark for him. The Bills can attribute much of their success to Gabe Davis, who picked up 130 receiving yards and a touchdown, and Josh Allen, who rushed for 15 yards and two touchdowns. They had just enough and edged the Chargers out 24-22.

In your own words, this paragraph highlights your greatest career achievements and top skills. This only needs to be a short paragraph, no more than 3-4 sentences. Resume summary or objective statementĪfter your personal information, the next part is your resume summary. In Canada and the United States, adding a photo on your resume may hurt your chances of getting an interview because of strict discrimination laws and employment policies. If you make it further in the hiring process, the recruiter can ask you for additional identifying information. There’s no need to include personal information such as your date of birth or any personal identification number. We suggest that you only use social media profiles that apply to your desired job. In some roles, your online “brand” is crucial to your job. Most often, recruiters use social media searches only to see how you’ll fit into the company culture. The same rules apply to any social media profiles your potential employer wants to see. Before you add your profile to your resume, take some time to look it over and update information, include a professional photo and remove any inappropriate material. LinkedIn is the biggest global network for professionals and most recruiters expect that applicants have a profile. If you have a LinkedIn account, include that along with any relevant social media accounts. You may also choose to include a link to a website or portfolio, depending on the job. Focus on what makes you different than other candidates and what you offer that no one else can.Įven if your resume doesn’t lead to the job you are applying for now, a memorable resume can be pulled up later when another position opens.Īt the very least, the personal details section should include your email address, name and phone number. If you outline your relevant experience and skills, display what unique benefits you offer to the company and match yourself to the position, you grab the employer’s attention. They are often short on time and look for ways to quickly find solid candidates for each job.Ī resume can help you land your dream job if it’s written correctly.

Combined with a well-written cover letter, your resume gets you through the door for the job. Think of your resume as a one-page advertisement, and you are the product. No matter what type of resume layout you choose, it should be a snapshot of your relevant life and work experience, skills and communication ability. A well-written and well-formatted resume gets your foot in the door so you can wow them with your communication and personal interview skills. Recruiters may go through hundreds of resumes and only pick a few to interview. While your ultimate goal with a resume is to get a job, the first purpose it serves is to attract enough attention to get you an interview. Resume writing doesn’t have to be hard if you have the right tools and the best resume formats at your fingertips.

She was an elegant Buryat, middle-aged, with impossibly round, prominent cheekbones, like half-plums. “Congratulations on your new president,” said our guide for the day. The Buryat desk clerk grinned, not meeting my eyes. Ulan-Ude also has the world’s largest Lenin head, something to put on your list.įirst post-inauguration Donald Trump sighting: On a TV in the lobby of the Hotel Geser in downtown Ulan-Ude. Buryats, a Mongolian people, make up close to a third of the population of Buryatia, and Ulan-Ude is an interesting-looking city, with its mix of Mongolian, old Russian and Soviet architecture. Shortly after that, we arrived in Ulan-Ude, capital of the Buryatia Republic. When I woke up, there were notifications on my phone (it turns out you can get internet over data along most of the Trans-Siberian Railway route), informing me that “Donald Trump Has Been Inaugurated 45 th President of the United States.” I didn’t want to use the data to click on the articles. I slept through Trump’s inauguration, as our train rumbled through snow-covered villages, a modest city or two. Siberia, you should know, is beautiful, at times breathtakingly gorgeous, from our train a succession of little towns with brightly painted, steep-roofed wooden houses, onion-domed churches, frozen rivers, endless birch and pine forests frosted with snow, vistas of ice, all under a bluebird sky. Ulan Ude and Irkutsk were two of those places, on opposite ends of Lake Baikal, so those would be our stops between Vladivostok and Moscow. The idea of this trip, besides taking the Trans-Siberian Railway all the way from beginning to end (or maybe it was the other way around, given we started in Vladivostok), was visiting some of the places Olga’s family had lived and worked in. I traveled with a good friend and her mom, whose parents were both born in Russia. Dealing with the cold would give me something to focus on other than the reality of a President Trump.Īlso, there was the whole Trump/Putin bromance, Russia hacked our election deal, and I’m a sucker for cheap irony. It was far away, a place associated with cold, exile and gulags, with a potential for isolation - could we even get the internet on the Trans-Siberian Railway? I liked the idea that we were going at the coldest time of the year. Spending Inauguration Day in Siberia seemed like a great idea. I sure didn’t want to see Donald Trump’s inauguration. I did not want to accept that an extremely accomplished, strong, smart woman had lost to a sexist, racist reality TV star. 8, when it became clear Trump would be president, I raged. I’m not going to pretend to be neutral here: On Nov. But there was always YouTube, I told myself, and when opportunities come up to go someplace like Siberia and take the Trans-Siberian Railway, the world’s longest railway route, all the way from Vladivostok to Moscow, I take them. Seeing the first woman president of the United States sworn in, it was a moment in history I hadn’t wanted to miss. I just thought I’d be missing Hillary Clinton’s inauguration instead. Which is to say, I’d known for a few months that I’d be in Siberia on Jan. I did not expect to be in Siberia for Donald Trump’s inauguration.

Organizing media is done by moving clips around on the timeline. Basically, with few exceptions, you will likely be able to import clips in whatever format you prefer. Windows Movie Maker lets you import and organize footage in several formats, including WMV/ASF, AVI, WMA, MP3, MP4, MPG, WAV, and MOV, among a few others. So, what key features can you expect when working with Windows Movie Maker? Whether you’re editing together a few clips for fun, or you’re editing a feature-length film, there are a few key features that you’ll need, including: Like most video editing software, Windows Movie Maker takes a little getting used to, but once you’ve found the tools and features you need, it can get the job. And there’s also a zoom control at the bottom of the screen that lets you zoom in and out on clip thumbnails to cut down on guesswork when you’re doing detailed editing on specific frames.Ĭropping and splitting video clips can be done on the fly by hovering your cursor over the area where you want to make a cut, or you can use the edit buttons for more precision. The size options on the thumbnails make it a little easier to handle long and short clips when you’re working on tiny details or when you’re making bigger edits on a longer project. This gives you a fairly quick and easy way to see where the loudest and quietest parts of your video are. When editing audio for a video clip, you have the option to look at the audio waveform for each thumbnail clip. Each clip looks like a long thumbnail image with a clear image of the first frame and faded images of the subsequent frames.

The installer then prompts you through the installation process, and you can then open Windows Movie Player on your desktop or laptop and start editing. Users could then toggle the apps on and off to choose which ones they wanted to install and which they wanted to leave out. Because Windows Movie Maker was included in Microsoft’s Essentials bundle, a single installer would open for all of the apps in the bundle.

After that, skeptics had no doubts about the significance of the Periodic table. Their properties exactly matched the characteristics described by Mendeleev. Still, within 15 years, new elements such as gallium, scandium, and germanium were discovered. Then he correlated this with the valencies in typical compounds and the chemical properties of the elements.Īt first, Mendeleev’s colleagues reacted with suspicion to his theory of missing elements. So he decided to leave empty cells in his table while carefully studying the dynamics of the increase in atomic weights. Even earlier (February 1869), the scientific notice of the discovery was sent to the world’s leading chemists.Īccording to Mendeleev, there should be elements with the same valence in one column. Mendeleev published his first sketch of the periodic table in 1869 in the article “Correlation of properties with the atomic weight of elements” (in the journal of the Russian Chemical Society). They attempted to create a sequence of elements in increasing order of atomic mass and then separate them into groups due to similar chemical properties.īut the first scientist who was able to combine and organize all the knowledge accumulated by humanity about chemical elements into a structured table was the Russian scientist Dmitry Ivanovich Mendelev. At that time, all chemists of the world tried to structure all known elements into a single concept. Who discovered the periodic table of chemical elements?īy the middle of the 19th century, scientists had already discovered 63 elements from the modern periodic table. In the table, periods are rows, and groups are columns. Also, the elements in the table are ordered according to the electronic configuration of the atoms and the repeated chemical properties. It is always positive.įor example, hydrogen has a nucleus charge of +1, calcium will have +20, and so on. And the nuclear charge, in turn, is the number of a chemical element in the table. If you look closely at the structure of the table, you will notice a periodic change in the properties of the elements with increasing nuclear charge. Why is it called “periodic”? The answer to this question is straightforward. Why do we call the table “periodic”?īut let’s get back to the periodic table of chemical elements. 94 of them are found in nature (some only in trace amounts), and the others 24 are artificially synthesized.Ītoms of various elements interact to form compounds in different combinations and form a huge amount of natural and synthetic substances. To date, 118 chemical elements are known. For example, Nitrogen is indicated as “N”, Aluminum as “Al”, Helium as “He”, Iodine as “I”. As a rule, the first letters of its Latin name are used. The symbol for a chemical element consists of one or two letters. Each chemical element has a name and is indicated by a symbol or chemical sign. Atoms of different chemical elements differ in mass, size, structure, and properties. What is a chemical element?Ī chemical element is a specific type of atom with an individual set of protons and neutrons in the nucleus and electrons that revolve around the nucleus. In order to realize the structure of the periodic table of chemical elements, you must first understand what a chemical element is. Nowadays, the formulation of this law is as follows: the elements of the table have changes in their properties in accordance with certain periods. This is a clear example of the periodic law, which was formulated by Dmitry Ivanovich Mendeleev in 1869. The Periodic table of chemical elements is a structured table with a sequence of chemical elements arranged in strict order with the periodic law of chemistry. What is the Periodic table of chemical elements? While PTSD was first recognized in the DSM-3, the DSM-5 is the most recent version of the DSM at this time, and some adaptations have been made in the DSM over the years to better diagnose and categorize mental health conditions. The DSM or diagnostic and statistical manual of mental disorders is used by medical and mental health professionals to diagnose mental disorders, such as PTSD, major depressive disorder, bipolar disorder, personality disorders, and anxiety disorders. Most people first recognized PTSD in the year 1980, when it was included in the third publication and release of the DSM. PTSD is characterized by symptoms such as re-experiencing a traumatic event through flashbacks or nightmares, hypervigilance, and avoidance of places, things, or events that remind one of the traumatic experiences they endured. After someone experiences trauma, they may have difficulty recovering from the said event and may develop PTSD. PTSD or post-traumatic stress disorder is, in some ways, exactly what it sounds like. So, what is PTSD? How do you know if you have it? PTSD can develop after any traumatic event. Despite being painted as a disorder that’s only for those who’ve been in the military for so long, that is not the only potential cause or trauma related to PTSD. Additionally, children and teens can be diagnosed with PTSD. It can affect people of any gender, but PTSD is actually more likely to occur in women – twice as likely, in fact. According to the American Psychological Association (APA), post-traumatic stress disorder or PTSD impacts roughly 3.5% of adults aged 18 or older in the United States. |
