Define Osmotic Pressure Online Biology Tutors Tutorpace
Define Osmotic Pressure Online Biology Tutors Tutorpace The movement of particles from a region of higher concentration to a region of lower concentration through a semi permeable membrane is called osmosis. The direction and rate of osmosis depend on the pressure gradient and concentration gradient. The osmotic pressure can be defined as the actual hydrostatic pressure (pressure related to water) which develops in a solution due to the presence of dissolved solutes when it is separated from pure water by means of a semipermeable membrane. The magnitude of the osmotic pressure is a function of solute concentration in a solution. It is higher in the case of xerophytes as compared to mesophytes while mesophytes have higher osmotic pressure than hydrophytes. It is also noted that an isolated solution without solute, and not bounded by any membrane, has no osmotic pressure. This negative osmotic pressure is called osmotic potential. For the development of osmotic pressure a confined space is required. Numerically osmotic pressure is equivalent to the osmotic potential, but the sign is opposite. Osmotic pressure is the positive pressure applied, while osmotic potential is negative. Example the function of solute concentration in a solution is the magnitude of osmotic potential. Such a solution has an osmotic potential which is a negative of osmotic pressure.

A Student Perspective on Brigham Young University
A Student Perspective on Brigham Young University Joseph is a current senior at Brigham Young University. He is majoring in psychology, and specializes in Algebra 2 tutoring, ACT English tutoring, and a number of other subjects. Below, he shares his experience at Brigham Young University: Describe the campus setting and transportation options. Joseph: The campus is located in a valley at the base of a portion of the Wasatch Mountains. Most students live in off-campus housing thats within a 20-minute walk from campus. Its very easy to do without a car and still maintain a good social life. You can walk to the campus, a good portion of the other apartment complexes, grocery stores, and even hiking trails. The campus is located in a town of about 100,000, but the downtown area does not have much to it. As far as safety goes, it was rated the safest college campus in America. Buses and a train are available for travel north to Orem or Salt Lake City. A car and bike are nice for convenience, but definitely not necessary. How available are the professors, academic advisers, and teaching assistants? Joseph:All professors are required by the university to hold office hours, so the only factors stopping you from getting one-on-one help from them are your own fears to approach them. I have found it easy to schedule an appointment with academic advisers. Most classes have one or two teaching assistants per 50 students, each with their own office hours. The TAs often host review sessions of their own. In physics, math, and psychology there are labs open all day where you can go to get help from TAs. How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Joseph:Most of the students live in off-campus housing. Theres quite a variety of housing quality, from the rundown to nice and modern housing. Many students buy and cook their own food, but there are dining areas on campus where meal plans can be used. The culture is very friendly and people are usually quite open to making new friends. Which majors/programs are best represented and supported? Joseph:The BYU Marriott School of Business is often rated top five in the country. There are also particularly strong programs in the engineering department. Since its a large university, most areas of study are well-represented. I chose to major in psychology. The university has a large faculty for the program with plenty of opportunities for involvement. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Joseph:Its very easy to make friends. You can go into the lunch room and sit by somebody and theyre usually very happy to talk. Most people are closest with their roommates; its a little bit more difficult to become close friends with people otherwise. Theres no greek life on campus. How helpful is the Career Centerand other student support services? Joseph:I have not personally used the Career Center or other services other than advisement, but the list of services offered is quite extensive. There are often career fairs that have many reputable companies in attendance. How are the various study areas such aslibraries, the student union, and dorm lounges? Joseph:The library usually has enough room; its one of the best college libraries in the country. It can get a little crowded, in which case most of the other buildings on campus have study areas which are quite spacious. Describe the surrounding town. Joseph:Provo itself doesnt have much to do, so students usually hang out around campus with each other. Salt Lake City has a bit more to do, but its an hour or more by car. There are a lot of opportunities for outdoor recreation. There are three canyons into the mountains within a 30-minute drive, each with near hiking trails. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Joseph:The student body size is around 30,000. There tends to be large classes for generals and early in your major, which can be a little bit ineffective. For classes where size is important and later in the major, they hold between 20 and 40 people. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Joseph:I am currently enrolled in a research and writing class for political science, and the way the class is organized is like a well-oiled machine. There is one TA, each with office hours, for every 20 students. The teacher is very funny and keeps lectures entertaining. He even has large candy bars that he gives out when people answer questions. Hes put a lot of energy into teaching methods that are effective. The papers are graded at a really high level, but because of the support system, the class helps students to truly reach this level.

Online Understanding Calculus Tutors
Online Understanding Calculus Tutors Calculus is an important section of Mathematics which involves a detailed study about different functions and behavior of those functions. Calculus is sub-divided into two important branches which are finding derivatives of functions and finding integrals of functions. Derivatives of a function gives the rate of change of one variable with respect to the other and integrals of functions analyses the area covered under the graph of a given function. In order to analyze math in advanced level, it is very important to understand calculus as it helps us understand functions in a much detailed manner. Example 1: Use the derivative method to find the slope of the given straight line, f(x) = 5x + 2. In order to find the derivative, we can use the Power rule of the Derivatives: d(xn)/dx = n * xn-1 We can distribute the derivative to both the terms: d(5x + 2)/dx [ d(5x)/ dx ] + [ d(2)/ dx ] Using the above formula, we get 5(x1-1) + 0 = 5 Hence the slope or the derivative of the given straight line is 5. Example 2: Calculate the integral of the function, f(x) = 3x2 8x. Given function: f(x) = 3x2 8x. In order to find the integral of the given function, we can use the formula: xn dx= x(n+1)/ (n+1) Applying the above formula for the given function, we get (fx) dx = 3 * x2+1/(2 + 1) 8 * x1+1/(1 + 1) + c f(x)dx = 3x3/3 8x2/2 + c We can simplify it as: f(x)dx = x3 4x2 + c
A Look Inside the Thoughts of a Hiring Manager - Introvert Whisperer
Introvert Whisperer / A Look Inside the Thoughts of a Hiring Manager - Introvert Whisperer A Look Inside the Thoughts of a Hiring Manager Havenât you ever wished you could hear the thoughts going on inside the head of a hiring manager? If you had the inside track it would help you understand whatâs going on in the process and how to get a competitive advantage. Let me offer you that insight. I hired hundreds of people in my 21 years as a manager and also hundreds more as a recruiter. I also have compared my experience with other managers to help me improve my process and to broaden my perspective on hiring. Letâs start at the beginning of the process: - This is a PAIN⦠Iâm already working 10-12 hours a day just to get my work done and now Iâve got more work to do just to hire someone. Who knows if the person I hire will work out and if they donât then my life is seriously miserable. Yep, I think a root canal is sounding like more fun. - I want this to be over quickly. Maybe I can get this over fast. I keep a stash of resumes of people who have been referred to me in my desk, let me start looking at those. I really hope one of these matches what Iâm looking for because if it does, I might get this over A.S.A.P.! - Iâll ask around. Iâm going to call and email a few people I know that always seem to be well connected. Iâll find out if they have any hot resumes or know of people they think would be good at this job. Iâll make it known to lots of people I know so maybe I can speed up this process and I wonât have to post. My history tells me that referrals are always the best hires anyway. - I guess I better write job descriptions and posting. Iâm going to see if I can find an old job posting I used last year to copy from so I donât have to start with a blank page. Maybe I can find someone elseâs job posting and just reuse the parts of theirs that work for this job. I never know what to write for a job posting anyway. This is just another part of this whole process that I hate. I dread the idea that weâd actually have to go so far as to post this online. The deluge of resumes is a killer. The process has started: - I canât read another resume! OMG! All of these resumes look and sound alike. How am I supposed to pick from this pile of 50 resumes? â" And there are another 300 in the system Iâm sure are the same. None of these resumeâs stand out unless they are seriously bad or unqualified. At least the bad ones are somewhat entertaining. I canât believe that someone with none of my hiring criteria is even bothering to send me a resumeâ¦it looks like they completely ignored my hiring criteria. - Now Iâve picked a handful of resumes, someone saves me from this misery! So, Iâve picked out 10 resumes that all look like they can do the job. Iâm still holding out some hope that one of my âfeelersâ is still going to work out and a referral calls me. - Phone screen time â" I actually donât mind this part. The fun thing about calling these applicants is that most of the time I donât actually get them so I leave a voicemail. If I donât hear back from those people in 24 hours, I pitch the resume and move on to someone else. I use follow up and attention to things like voicemail as part of my screening process. Itâs amazing how many people are soooo bad at responding in a timely manner. Theyâre either rude or stupid â" both things I donât want to hire. - Phone screen for real. I still like this part of the process because all Iâm trying to do now is find a reason to not interview someone in person. Short and sweet with only a couple of questions. I can get this done before lunch. Iâm still hoping for a referral. Final phases: - UCK! Interviewing. Talk about a contrived event. Iâve tried to figure out what the best questions are to ask all the applicants so I can compare them all when Iâm done. BUT, it only marginally helps the decision process in the end. I might have a trusted staff member or peer interview my top candidates to help me sort out my decision but even that isnât always a good thing to do. At some point, interviewing is boring because its almost like reading resumes â" they all start sounding the same. - Iâm still hoping for a referral. I donât care how far along I am in this process. If the right person were to come along, Iâd dump all these candidates for a person my network endorses. - Decision time. ? Itâs been 3 weeks since I interviewed the last candidate â" 5 weeks from the first interview. I had a big presentation to do and it took all my time, then I had some other business issues to deal with. I didnât think it would take this long to get around to making a decision but thatâs how business works. Iâve got to take care of priorities and hiring just had to take second place. I think I remember which person I thought Iâd choose. I hope looking over the resumes and my interview notes help jog my memory. I think this is the one. Iâm sure this person can do the work but mostly I really liked them, which makes me hopeful that we can work together well. Thatâs what its all about. Iâll get with HR and work up an offer. Who knows how long that will take? The hiring process for most hiring managers is not a fun activity. Itâs extra work and never goes as fast as anyone thinks it should. At some point, all the resumes and candidates blend together unless someone just happens to stand out. That doesnât happen very much. At the end of the day, the manager hires the person they liked most because they all appeared to be able to do the job. What should a job seeker pull out of this? They should focus on referrals and networking. You will always stand out if you do. Bonus Tip: Adapting is key to your career survival, growth, and advancement.

An Intro to the New AP Computer Science Principles Course
An Intro to the New AP Computer Science Principles Course While many students fear that their high school and even college education may fail to get them a job upon graduation, those with a background in computer science seldom have reason to worry. The tech industry continues to grow and change, and theres no signs of stopping. It should come as no surprise, then, that schools will begin offering an AP Computer Science Principles course in the fall of 2016. The course, which will emphasize creative ways to solve problems in the larger world, is meant to prepare students for both college and employment situations. Rightfully so skills in computer science are required or are strongly beneficial for nearly every field of employment. Computer science skills have become essential for students entering the workforce. With this in mind, here is an intro to the new AP Computer Science Principles course. AP Computer Science Principles development The AP Computer Science Principles course has been in development since 2008 and has been the collaborative effort of more than 50 high school and higher education teachers. The course is meant to be interactive, current, and relevant. AP Computer Science Principles content Instead of simply reviewing a programming language, the course will cover technology and programming as a solution for computer issues. It will focus on computers and their interaction with and to society not revolving around computers entirely, but examining the ways computing has influenced other fields. In addition to computer science, the course will build communication and collaboration skills, emphasize problem solving as individuals and as groups, and examine technology in the world. The class will focus on seven big ideas entrenched in the principles of STEM education: creativity, abstraction, data and information, algorithms, programming, the Internet, and global impact. AP Computer Science Principlesframework This class is meant to mimic a first semester introduction to college computing course. The course teaches the computational thinkingpractices necessary for developing the knowledge and skills to analyze data and communicate. Because the course focuses around seven big ideas, each uses questions and concepts to connect every idea to the next. These questions tend to be large-scale questions that rely on information learned in previous sections. As with many AP courses, the Computer Science Principles course features thorough learning objectives that provide students with clear goals for the course and the AP exam to follow. Next to each learning objective (which are numbered so that their relationship to big ideas and enduring understandings is clear), students will find essential knowledge statements, which will help students perform well on the AP exam and in every section of the course. This course will be creative, iterative, and exploratory, which makes it very useful for a variety of learners. AP Computer Science Principles test The AP test for this course will consist of two parts. First, the AP exam and then the through-course AP assessment. The AP examwill be administered as a multiple choice test filled out with paper and pencil. Students will be required to demonstrate their understanding of course learning objectives. In the through-course assessment, students will complete two performance tasks involving programming. Theyll look at student learningin a more comprehensive way than can be achieved on a timed test. Students will perform their knowledge in a real world way. Overall, the course looks to provide valuable job skills to students interested in technology.
Transition Your Students into a Good Second Half of the School Year
Transition Your Students into a Good Second Half of the School Year Motivating your students after the holiday break can be difficult. Many students struggle to get back into the routine of homework and studying after a couple of weeks off, with the end of the school year in sight and their brains still in vacation mode. What can you do? Here are a few tips on how to re-energize your students for the spring semester: Ease into it. Plan out your first month back to school strategically, saving the more intensive work for a couple weeks into the term. If possible, use the first week back as a refresher on where you left off before holiday break. Engage your students in some planning. Set some goals as a class. You have milestones to reach between now and spring break (and the end of the school year), but invite your students to contribute their ideas on exactly how youll do so. Have students write personal goals. This can be a very inspiring exercise, getting students into the right mindset to make the most of the rest of the school year. Talk about the importance of setting SMART goals that are specific, measurable, achievable, realistic, and t Clean up and clean out. Your classroom might not be as tidy and organized as it was at the beginning of the school year, and most likely, neither are your students backpacks, desks, and binders. Take some time to get your class organized and back on track as the year begins. Be enthusiastic. Your energy will be contagious, so share with your students what youre excited about this semester, and open the discussion to learn about what theyre looking forward to as well. Talk about some of the fun projects or units you have coming up. Take a student-centered approach to get them engaged. With a little effort, youll get this year off to a great start. Lay the foundation for success with some planningand a lot of excitement.
Tutorfair Resource Sharing Day!
Tutorfair Resource Sharing Day! Tutorfair holds a Tutor resource sharing day! To help tutors share ideas and be the best that they can be for their students we held at resource sharing event at Tutorfair headquarters on Friday 13th of January. As a tutor you develop your own unique teaching style and amass a collection of great resources to help your students with the more challenging topics. The difficulty can sometimes occur when, as a tutor, you want to learn new techniques or ask questions about areas that you are less familiar with. At Tutorfair we are aiming to solve this by bringing great tutors together where they can share learning materials, get hints and tips, as well as support from fellow tutors. On the day we had some great learning resources to share. Around 15 tutors, specialising in a range of subjects, gathered to impart their knowledge and expertise. Adam S, a maths tutor and qualified teacher, shared a great game he uses with this students to help explain probability. Have a go at playing it yourself here! Another great tutor Raphael O gave us a great way of using less paper. Replace paper with a whiteboard and pen and make teaching more interactive and save money on paper at the same time! With range of tutors from maths, science and language backgrounds there were some interesting opportunities to learn. It might surprise you how tutoring tips can be shared even across different subject areas. It was clear from this event that effective tutoring requires fantastic resources and passionate educators who are open to new ideas. If you would like to access some of these resources please visit our fantastic resource centre. If you are a tutor looking to take part there will be more events coming up every month.

?? Three exercises to manage your mental fitness when you feel the exam pressure rising
?? Three exercises to manage your mental fitness when you feel the exam pressure rising Three exercises to manage your mental fitness when you feel the exam pressure rising Preparing for exams is like an athlete preparing for a race â" it isnât just about the technical revision, it is also important to look at the whole picture â" diet, sleep, down time for rest and recuperation, and mental preparation. We know stress can be a good thing â" it can certainly give an athlete the boost they need to get across the finish line, but like anything too much can be a bad thing and can derail the best efforts and intentions.In this article I will share three things you can do to support your mental health whilst you study, and three steps to take if you feel your stress levels are rising and affecting your ability to study.But before I talk about what you can do to manage your stress, I want to explain what happens in your brain when you are too stressed and why this is important.One brain â" two mindsThink of yourself as having one brain but two minds - the first part is our intellectual mind (the left pre-frontal cortex). When we are in this part we are p ositive, wise, and will make the best possible decisions at any given time. So obviously this is where we want to be! The second part is our primitive mind (the limbic system) and this is the part that controls our fight or flight response â" our survival instinct. This part is really useful when we face life or death situations such as facing a wild animal like a tiger, but the thing is we donât really face many life or death situations anymore. But guess what? Your primitive mind still reacts in the same way. Those pesky negative thoughtsSo say you start thinking about your revision and your mind drifts to negative thoughts â" you think about all the work you have to do and you donât know how you are going to get through it, you might think that youâre not smart enough, youâre going to fail, and lots of other negative thoughts like that. Now you start to feel the stress build up. You might notice it â" that ball of tension in your stomach, your heart rate is increasing, your muscles are tensing, you canât focus on anything, you canât sleep, or you get stuck doing unhelpful things like spending too much time on Instagram or Snapchat. Exam Prep â" itâs coming to get me!This is happening because although your intellectual mind sees the exams as what they really are, your primitive mind sees them as life threatening as a tiger attack! Now all it wants you to do is fight, run away or freeze in the face of this imminent danger, and that usually results in unhelpful behaviours like organising your study plan over and over but not actually doing any study, leaving things to the last minute, or just not being able to focus on anything at all. Another unfortunate thing is if the primitive mind is in control it also reduces our intelligence and our ability to cope with life. Not so great when youâre trying to study for your exams is it?But there are things you can do to keep you in your intellectual mind so you can perform at your best.Three tools t o support your mental healthLike I said at the start, just as an athlete has a whole load of tools in their kit bag to ensure success, you have too. The three main ones are:1. SleepI canât emphasise this one enough, and this is because during sleep, particularly when we dream, we clear out the stress and anxiety built up during the day. It has been found that even one poor nightâs sleep can affect brain function. So if you do anything I would recommend getting on top of this. I like these great tips from Harvard Medical School.2. ExerciseOften when you are studying you think you donât have time to exercise, or you can put it off for another day, but exercise is so important for three reasons:It releases positive neurotransmitters and hormones (like serotonin, the âfeel goodâ hormone) which make you feel happier, braver and able to cope better with the stresses of life (like exams!).It helps to relax your muscles, and when that happens it sends a message to the mind that it can relax too.It makes you smarter! How? Because when we exercise we grow new neurons and pathways in our brain, and there are reports of students in America increasing their grades by doing regular exercise. One student said he went from getting Bâs and Câs to Aâs and Bâs just by exercising before class every day.How much exercise?Aim for aerobic exercise where you are puffing a bit and find it difficult to talk for about 25-40 minutes, 3 to 4 times a week. If you did some exercise every day that would be a bonus, but donât put too much pressure on yourself if that seems too much. Even going for a walk for 10 minutes can help boost your mood. 3. Keep doing things you enjoyItâs very tempting to put on hold all your hobbies, stop seeing friends or doing anything fun whilst you are revising because you donât have time for it. Obviously it is important to devote adequate time to your revision, but to stop doing all the things you enjoy will have a detrimental effect on your stress levels. Because when we do things we enjoy, we release those positive neurotransmitters that keep us happy, healthy and confident.So fit in some enjoyable activities into your schedule â"your mind and body will love you for it!Three steps if you feel the Stress buildingSleep, exercise and fun activities support your mental wellbeing, but what do you do if you feel the stress building up and you canât focus or concentrate? Iâm now going to share a process based on my hypnotherapy sessions which can help. Even if you are pretty good at staying focused and on top of things, incorporating this into your daily practice will still benefit you.Ste p 1: Write down positive thoughtsWrite down all the good things that have recently happened or are happening in your life, or all the things you are grateful for. Think of 10 things if you can, and make sure you write them down. It could literally be as small as you enjoyed your walk this morning, or it was great seeing your best friend on the weekend. The reason for this is also based in science â" if you are thinking about good things you canât be in your primitive mind because the primitive mind is always negative. I had a client who suffered from panic attacks, and when they felt one coming on they remembered their hypnotherapy sessions and started thinking about all the good things, and it worked! They were able to stop the panic attack. Step 2: Work out the next stepThink about your âTo Doâ list. What one small thing would make the most difference to your happiness right now? The reason why this question is important because often the stress builds up when there is too much to do, so what can happen is you get stuck and do nothing, or the work you do is ineffective (the headless chicken scenario). It could literally be âopen my maths text book to page 7, and start the first example questionâ. Think about the next step right in front of you, not the end result. Because taking one step at a time will get you working towards achieving your goals.Step 3: Listen to a relaxation/mindfulness meditation Doing this will get your mind into a calm mental state we call âtranceâ. The reason why this is useful is that it allows access to the subconscious mind, where you have the potential to make powerful positive changes. It also helps to clear the stress out of your system. There are a lot of different Apps or relaxation/meditation downloads to try. Whatever you choose I would recommend it is at least 20 minutes long. I have a free relaxation download which is approx. 30 minutes long. It is focused on reducing stress and increasing confidence, but you will find benefit for whatever you need help with right now. Remember though, just like an athlete you donât become good at something overnight â" you have to practice at it. So putting the above into practice on a regular basis will help you deal with your stress and get you thinking positively, acting positively, and performing at your best. Good luck!
