The 12 Spiritual Laws Of The Universe

How we operate in the world has everything to do with how the universe operates itself. After all, it's said we humans are simply the universe experiencing itself through our existence.
Did you know the Law of Attraction is not the only law of the universe?
With the rising trend of spirituality and our ability to manifest our deepest desires, becoming aware of the twelve laws of the universe has the ability to seriously change your life.
1. Law of Divine Oneness
The Law of Divine Oneness is the foundation in which the rest of the laws of the universe are built upon. This law enforces the idea that we are all connected to one source. Every cell, fibre, atom, molecule, and being of your existence is connected to the greater universe around us.
Understanding the Law of Divine Oneness is to understand that your actions and decisions directly impact the collective consciousness of the universe, creating a ripple effect throughout space and time.
When you meditate or do breathwork, you become connected to that all-being source. Knowing everything and everyone around you is connected allows you to move through life with more awareness and respect for yourself and others.
2. Law of Vibration
The Law of Vibration is the first step towards manifesting our desires, because how we vibrate in this world affects what we attract to us.
Manifesting is not just about writing down your goals and repeating them to yourself over and over each day. In order to truly get everything you want in this life, you have to match the vibration of whatever it is you're trying to achieve.
Everything in this universe is energy, and energy has a vibration. Energy particles are moving at different frequencies all around you at this precise moment. In fact, you are vibrating, too, whether you know it or not. In order to use this law to your benefit, you have to beome aware of how you vibrate in this life.
Are you vibing high or low? You can tell by your emotions. If you're feeling down, your vibration is low. If you're elated and positive, you have a high vibration. These levels of vibration directly correspond to how happy you are in life and how you view the blessings around you.
3. Law of Correspondence
The Law of Correspondence is all about patterns. Everything is a pattern, and we often don't see or understand the cycles that play a part of our lives until we do some major introspection. The situations we find ourselves in simply mirror what's going on within ourselves.
These patterns are either amazing for our growth or detrimental to it; however, we always have the ability to change course. Our subconsious mind makes up all the habits and patterns we willingly (or unwillingly) repeat.
For example, my parents start each day with coffee, no matter what. Growing up, I'd watch as they would wake up and directly turn the coffee pot on, and then proceed to drink coffee all day. Drinking an insane amount of coffee was normal in my household, and growing up, my brothers and I all took on this habit.
Recently I noticed I was only ever drinking half a cup of coffee in the mornings before letting it go cold, and I'd waste entire pots of coffee just because I'd wake up and start the coffee machine, with no real desire to drink it. Too much coffee gives me anxiety, makes me feel gross, stains my teeth, and my skin started breaking out due to the sugary milk alternative creamers I'd put in my cup. When I realized how internalized this habit was, I learned that this habit was passed down from my parents and it was not even my own. After noticing this, it was easy for me to cut out caffiene and switch to tea. I feel better and I'm reclaiming my power by making my own conscious decisions.
4. Law of Attraction
This is the law most people are familiar with, but if you don't understand how the rest of the laws work, chances are you'll be unsuccessful at manifesting whatever it is you desire.
Like attacts like. Whatever it is that you are thinking about, you will attract. When you give something all your energy, you're asking for that same energy back. Ever notice when you're having a bad day, things continue to go wrong? You might start the day with stubbing your toe, then you get a parking ticket, then you forget to pick up ingredients for dinner, and you go to bed thinking, "Wow, that day sucked."
That's because you're focusing on the negative things that happen to you, therefore you attract more negativity. However, consciously noticing these negative thoughts is the first step to becoming self-aware.
Try to move through your day with a positive attitude, and you'll be amazed at all the good you attract. This can even be a smile from a stranger, how good your coffee tastes, or a phone call from an old friend. Notice when the little blessings come into your life and bigger ones are sure to follow.
5. Law of Inspired Action
Practicing the Law of Inspired Action + Law of Vibration + Law of Attraction is where you'll start to see massive changes in your every day life.
The Law of Inspired Action is just that -- taking action! You know when you have that voice inside you, that gut instinct telling you that you should act on your ideas? That's the one.
Has a situation ever occured where you knew you should say or do something, but instead you stayed quiet? You know that feeling of regret you get? Yeah, that's the universe testing you to see if you'll actually take inspired action towards your goals.
Becoming aligned with your energy levels, manifestations, and taking baby steps is what's going to make you successful. What you think about all day matters, but how you respond is what the Law of Inspired Action is all about. It's all about trusting your intuition, which is essentially trusting the universe.
6. Law of Perpetual Transmutation of Energy
As we learned earlier, everything is energy. The Law of Perpetual Transmutation of Energy, put simply, means that there is a never-ending supply of energy around us and it is always changing to fit our energy levels.
This means you have the ability to transform your life by changing the energy around you. The smallest actions have the biggest effect. Think of dancing, or singing in the car, or doing a quick breathwork exercise. When you do these activities, your energy changes and transforms into one with a higher vibration.
Personally, I find that starting the day off with intention is the best way to change stale or negative energy within myself. By reserving the mornings for yourself -- no phone, no social media, no outside influences -- you can sit with yourself and figure out what it is you need to do for yourself every day. I like to wake up, do a quick work out, meditate, journal, read, and write my affirmations. By honouring what your body and mind needs, you have the ability to alter the energy within you and have the best day ever.
7. Law of Cause and Effect
The Law of Cause and Effect is taught to us when we're kids, usually to warn us that for for every action we take, there is a consequence. This law is also known as the Law of Karma. Whatever you put out there, you get back.
When you are doing good for the community, you are often rewarded for it either directly (like financial compensation) or indirectly. You might get recognition in the newspaper, or you might make a new connection that helps you move forward in whatever you are trying to achieve. However, if you are causing havoc and trouble and not acting in your highest self, you will often be punished for it.
Be aware of the actions you take, how they effect everyone around you, and how the universe is playing your decisions back to you. If you start to notice you've got a lot of negative situations coming your way, try to look within to see if it's something you can outwardly change.
8. Law of Compensation
Similarly to the previous law, if you're seeing blessing after blessing, this is usually because you're doing good in the world and the universe is rewarding you. As long as we're open to receiving (some people have blocks here, usually associated with the root chakra, so be aware of how well you give and recieve), we will be rewarded for our work.
Once I started writing on my blog about spiritual awakenings, posting on TikTok about my own spiritual journey, and speaking my truth to whoever would listen, I noticed more writing opportunities started to come my way, more important connections and friendships were being made, and my financial situation began to improve. When we are being our authentic selves and constantly spreading good vibes, the universe notices. The Law of Compensation is about making sure you are rewarded for your efforts.
9. Law of Relativity
How we relate to the world is directly proportionate to our perspective. The Law of Relativity states that no situation and no person is inherently good or bad. Good and bad are just words humans have made up so that we can judge a situation. How do we judge what a good day or a bad day is anyways? Aren't they all blessings?
The Law of Relativity reminds us that everybody has their own perspective and everything is subjective. We are the ones who label things good or bad, so we get to choose if something is "good" or "bad" when it happens to

The shipyard is a very dynamic work environment. For the shipfitter, the vessel or vessel section is the workplace and it is in a constant state of change while under construction, being refitted, or repaired. Shipfitters' work can constantly take them from one area to another on the vessel and they may encounter many fall hazards on a daily basis. For example, access cuts in deckplates to install or remove vessel components can create a hazard for anyone moving through the area if proper guarding is not used. Likewise, coverings such as staging boards or gratings can be moved from one location to another so care must be taken to ensure that temporary coverings are used.
Shipfitters must make sure that if they create a potential fall hazard that appropriate measures are put into place to protect fellow employees. Good housekeeping practices also reduce the potential for slips, trips and falls.

7 Lessons Learned as a College RA
Anyone who has lived in a college dorm knows what an RA is. They are seen as either the bossy tools who go out of their way to keep you from having fun or the useless nobodies that get a free room to do nothing and let chaos run throughout the halls. Well, I worked as a college RA (Resident Advisor, or Resident Assistant in some universities) while in college, and eventually got promoted to an RD (Resident Director), and a lot of my college experiences happened from the point of view of those positions. Here are ten lessons learned from being an RA/RD:
3DN Landing Strip
The theme one year in one of my residence halls
1. An RA isn't just that happy-go-lucky robot with a clipboard.
I thought I would start off by giving a clearer description of what an RA is and does, since I'm sure not many people are familiar. An RA is known as a Resident Advisor, or a Resident Assistant, in most colleges. The hiring process to become an RA is much more in depth than any other campus job (which I'll describe in more detail a bit later), as the responsibilities of an RA range in many areas. The following are the typical tasks an RA of your school would be responsible for:
– Rule enforcerProbably the most common task RAs are known for. They are in charge of abiding by the university residence hall policy and make sure students in their hall are following them as well. If they catch students not following policy, they are then to either give them warnings or write them up for a variety of punishments options.
– Room checksMaking sure that resident rooms in dorms and residence halls are clean, in proper living conditions, and ready for students to move in. Throughout the semester, they must ensure that the rooms continue to be in proper condition and do not present safety hazards to the students who live in it. They also must check the rooms when the students leave to make sure no damage has been done to it.
– AdvisingThis is where the "advisor" part comes into play. RAs are often put (whenever possible) in dorms with students in a major similar to themselves. RAs are trained to help students if they are having trouble with classes, with school, or even their personal lives. While not full-fledged counselors, RAs are given basic training to see if students are showing signs of depression, or giving basic counseling advice in emergency situations when a counselor isn't available.
From my experience, most RAs get the compensation of a paid room to themselves. In many schools, that's all they get (and sometimes they'll even have to share a room with another RA). In other schools, RAs get some better benefits. In addition to a free room, some schools give RAs a stipend (ranging from $20-$100 a week), free meal plans, free travel expenses for conferences, free goodies (like shirts, office supplies, mugs, caps, etc), and gift certificates/gift cards.
2. The RA hiring process is very selective and thorough.
Unlike other campus jobs, the position of RA holds a lot of power and responsibility, so it is no question that the interview process will be very comprehensive. Since I don't know how the interview process goes for every university in the country, I will merely provide the process for mine. I assume other schools are at least in a similar ball park.
The first step is the application. In addition to all the traditional application information that has to be provided, the RA application also puts you to answer essay questions that test your ethics and your desire to be an RA. If you hold the minimum GPA required and the questions show some ethical decision making and interest, you may be called to an interview. In that first interview, even more questions are asked in all sorts of different areas. You are given scenarios that RAs typically deal with and are asked how you would deal with them.
In addition, you are asked to prepare for the interview a 15 minute presentation of how your first RA 'wing meeting' will be (the initial meeting with your new residents at the beginning of the year). You are invited to be as creative as possible, and have decent knowledge of the housing policy handbook.
If you pass that interview, you will join a second group interview. All the candidates who have made it this far will be asked to participate in a one-day retreat kind of thing, where games will be played and team exercises will be performed. RDs and administrators will watch these games and see who works well with others and how these students perform in group settings. Being the loudest and most outgoing won't necessary land you the job. It's about being yourself, and not being afraid to take risks and talk to people. I would also recommend volunteering to be the first to do something in a game, even if you know you'll make a fool of yourself. In that initial time when they ask for volunteers and everyone is quiet, that is the best time to shine.
If you get selected to continue, you go through the last interview. This is usually with the assistant or associate director of housing. They tend to ask even more prodding questions to find out more about you, including experiences you've had that you think would be relevant to the job, and case studies to truly see how you think. If you can make it past this 3rd interview, you're almost an RA.
All that's left is the RA class. In some universities it's offered for elective credit, in others it isn't. This class ranges from 1 month to 3 months, once or twice a week, and the class covers just about everything an RA will do: administration, counseling, community-building, activities and events hosting, and even how to dress and nonverbal communication.
If you get through the class and manage to complete your assignments, you get placed in a residence hall and a room, go through another week of intensive training (the class is more on theory, and the training is more on practice) the week before school starts, and voila! You're an RA!
RA training is serious business.
RA training is serious business.
3. There are a lot of unadvertised perks of being an RA.
In my line of work, I've had several dinners with the university president, gotten backstage passes to Jeff Dunham and Tosh.O, and have even been picked as a volunteer for several hypnotists at my campus thanks to my VIP seating. In addition, I have been invited to complimentary trips to the Oshkosh aviation air show to represent our school, and other trips around the country for a variety of reasons.
The point I'm trying to make is that RAs receive many other benefits and opportunities than what you see in the job description. It really is a lot of fun and worth the experience. Plus, as student leaders, putting that you were an RA in college looks really good on resumes and grad school applications. It's one of the most versatile campus involvements you can have since they deal with so many areas.
In addition, you will be very well-known on campus. As an RA, you participate in orientation events, rallying up students for orientation activities, games, and programs. You usually get to know all the students in the building, and more importantly, they get to know you. If you're the super strict RA with the iron whip, the students will get to know you and avoid getting in trouble by you. If you make an effort to get to know the students, like saying hi in the hallway, going to the events you promote, etc., you will find that students will talk, and all of a sudden all sorts of people will be saying hi to you on campus, some you don't even know. This will continue to grow every year that you're an RA, until you become one of the most well-known students on campus, if you can handle that.
From personal experience, I went from a completely reserved, quiet student as a freshman on campus to one of the most well-known students in school. Case in point, I actually won Senior Class President my senior year and gave the graduation speech on graduation day. The biggest part of the popularity necessary to win that election was the people that I knew and the people that knew me.
It is a great feeling to have residents you had all year come back to you in their junior year and tell you thanks for helping shape their freshman year. Granted, many freshmen could care less, but there will be some that really appreciate your efforts.
4. Once you are an RA, you are always an RA.
Our university's housing department had a motto about being an RA: It's not a job, it's a lifestyle. The reason for this is because you are an RA 24/7, whether you want to be or not. You can't just "turn it off" when you go clubbing with your friends. Your residents will see you as their RA in the halls, and they'll see you as an RA in the clubs. They will also see you as their RA ten years from now when you encounter them and their kids at Disney World.
Many university staff members and student affairs professionals started out as RAs. Once they realize they could make an entire career out of doing stuff like that, they went for it. I'm one of those people. I became an RA for life, so to speak. So if you don't think you can handle the pressure of a job that becomes a part of your life, I wouldn't recommend being an RA. Otherwise, it'll be one of the most memorable jobs you'll ever have.
5. Being a Resident Director (RD) is pretty awesome too.

An extracellular protease was purified from a deep-sea psychrophilic bacterium strain DY-A which was identified as a Pseudomonas species. The optimal growth and protease-producing temperatures of the strain were all 10°C, and the protease was secreted only at temperatures under 20°C. The enzyme was most active at 40°C and at pH 10.0. It was inhibited by phenylmethyl sulfonylfluoride and diisopropyl fluorophosphate, indicating that it is a serine protease. Chelators such as EDTA, EGTA, 1,10-phenanthroline and 2,2′-bipyridyl produced a decrease of activity. The enzyme was sensitive to denaturing agents such as SDS, urea, and guanidine HCl and resistant to thiol-containing reducing agents such as dithiotreitol. The enzyme was active towards N-succinyl-Ala-Ala-Pro-Phe-p-nitroanilide and N-succinyl-Ala-Ala-Pro-Leu-p-nitroanilide. The native molecular mass of the enzyme determined by native PAGE and SDS-PAGE was 25 kDa.


Myth: Deadly Throwing Knives
The hero is cornered by the bad guys! Thinking quickly, she pulls out a brace of throwing knives. She flips the knives at two of her attackers. They go down, one clutching the knife embedded in his chest, the other lying still with a knife in his eye.
Stop doing this. Writers, moviemakers, everyone — just stop. Unless your hero is also wielding a magical get-out-of-physics free card, thrown knives don't work that way.
One of the most important aspects of a weapon is its stopping power. That is, its ability to stop your attacker in his tracks and render him incapable of hurting you any more. Some weapons, such as pepper spray, do this by inflicting severe pain and blindness. Others, like a sword, inflict enough physical damage to make further attacks impossible. Thrown knives are usually shown to be the latter sort of weapon. In reality, thrown knives have negligible stopping power because they lack three crucial elements: Mass, velocity, and accuracy.
It takes quite a lot of force to push a knife through skin and muscle and bone. The force with which a weapon hits its target is determined by its mass and its velocity. Knives are relatively light — an alleged throwing knife that I borrowed from a friend weighs only 50 grams (~1.8 oz). The heaviest knife in my collection still only weighs 310 grams (~11 oz). Throwing spears are far heavier. This modern example weighs in at 1134 grams (2 lbs 8 oz). A person who uses a knife in hand-to-hand combat benefits from the ability to put their body weight behind each thrust. A thrown knife, on the other hand, has only its own weight to work with. When you see a thrown knife in a movie that has buried itself up to its hilt in the bad guy's chest, what you are seeing a cliché with no basis in reality.
Light projectiles, such as bullets, have to rely on the other side of the equation: Velocity. The muzzle velocity of the popular 9 mm cartridge is usually around 400 m/s* (and this round is still not considered powerful enough for self-defense by many experts**). Compare this to a fastball, which travels at around 40 m/s — a speed that is still far above what can be achieved with a thrown knife. In fact, the fastest speed I could find for a thrown knife was only 16 m/s! The essential difference between the thrown knife and other ranged weapons is its lack of mechanical advantage. Bows use the energy stored in the curve of the limbs. Guns use chemical energy stored in gunpowder. Atlatls and slings are essentially big levers, multiplying the reach of the thrower's arm and thus the speed with which the dart or stone is thrown. A throwing knife, in contrast, relies solely on the velocity that a human arm can give it.
Finally, there's the question of accuracy. Even a light, slow projectile can be deadly if it hits its target in just the right way. Pointy projectiles — bullets, arrows, darts, and spears — travel pointy-end-first, making them aerodynamic. They often spin on their long axis for stability, like an American football. Knives, on the other hand, spin end-over-end. This creates comparatively large amounts of wind resistance. Thus, a thrown knife will lose what little velocity it has very quickly, making it next to useless at long range. The end-over-end spin also means that a knife spends very little time with its pointy end towards its target. Even a talented knife thrower is more likely to hit her target with the side or the butt of the knife rather than its point when the target is moving, as in a melee. Combine that with the knife's limited range, and your hero would probably be better off walking up to the bad guy and stabbing him in the face.
My favorite depiction of how thrown knives could be used in hand-to-hand combat is in Steven Brust's Taltos series. Our hero, Vlad, frequently gets himself into scrapes where he's outnumbered by people who are bigger than he is. One of his tricks for winning these fights is to throw a knife. The flying piece of pointy steel makes his opponent flinch, giving him an opening. He does not expect the knife to hit the person point-first, and he certainly doesn't count on the knife to kill anyone. Killing someone with a thrown knife is not impossible. It just isn't something that a character can rely on in a life-or-death situation.***
Even with years of training, throwing a knife is still slightly less effective for self-defense than throwing a large rock (rocks are cheaper, heavier, and sometimes more aerodynamic). Please, the next time you're arming your hero or her sidekicks for combat? Leave the throwing knives at home. They're silly, they're clichéd, and physics doesn't work like that.
* This number is a rough approximation. Actual speeds will vary by load and barrel length. However, it's still way faster than a knife.
** I will not indulge in the fast & light bullet vs. heavy & slow bullet debate here —.45 ACP still goes way faster than a knife.
*** Hunters who use throwing knives are usually after small game, like rabbits and squirrels. They also use very heavy knives.

 I am now so sad that I have never questioned this! I just watched Prince of Persia this morning and a lot of people die from thrown knives… but the hero does also appear to have a "get-out-of-physics-free" card. I will now be watching for this in stories (but I will probably still be ok with it if the writing is otherwise good!). (the writing in the movie was not good… not good at all.)
 2. Dirk Bruere says:
 And while we are on the subject…
 Time bombs that have flashing lights, a nice countdown, and colour coded wires – terrorists (or just sensible bombers) do not do things so conveniently. Add in one more cliché here – the above bomb connected to large slabs of plastic explosives, with the hero sweating about which wire to cut. He never thinks of just cutting away the explosive from around the detonator, or even removing the detonator from the mass.
 Then we have the hero escaping in a car, with the baddies shooting at it from less than 50m distance using (say) AK47s. In reality, he and everyone in that car are Swiss Cheese in about 3 seconds.
 3. Adam says:
 Good points, but sour grapes.
 If we were all perfectly concerned about the laws of physics, would we be fans of sci fi and fantasy? Don't think so. (Read: Warp drives, Dyson Spheres, etc., etc.)
 We can make the distinction. Reality is great, but you dismiss "fun factor" for cold reality. If we were that concerned about it, we'd all be reading non-fiction, now wouldn't we…?
 4. What you said goes double for shuriken. Watching a villain drop dead of a throwing star embedded a half inch in a chest or forehead is definitely a "naaah" moment.
 5. cs says:
 Sorry to disagree, Sarah but I do. I feel that there is room enough in literature, cinema etc for different mechanics.
 What you suggest is
 6. cs says:
 *please delete me last unfinished comment. My keyboard has crossed wires and now seems to send things without my intention.
 What you suggest is just one style, one is which the laws governing velocity in the story resemble the ones in our own world. But, as I often do, we turn to stories for escape.
 Sometimes I want to see Dragons who breath fire, spaceships the break light-speed, and (yes) ninjas with deadly throwing stars.
 Maybe say replace, "Stop doing this" and more "be clear what kind of story your writing". Because I think there is room enough on my shelves for both types of story.
 7. julian says:
 You should check out this youtube channel because real serious knife throwing is no-spin knife throwing, where the knife tip is ALWAYS pointed at the target.
 I'm sure this guy's videos don't show his worst throws, but when you are no-spinning the knives they are always pointed at the target, and probably don't have the wind resistance of spinning it either.
 8. Janet says:
 Sara's physics are spot on. (In round-numbers terms, anyway.) and the fact that a guy can stick a steel dart into celotex (soft wood-fiber insulating board) at the range of a few yards still does not make it a deadly weapon.
 Have you ever wondered why surgeons prefer to close large wounds with surgical staples instead of traditional stitches? Simple! It's amazingly hard to jam a needle big enough to drag a thread through skin, so Staples? Yes, Surgical glue? Yes, traditional stitching? Not so much, unless it's a place where self-dissolving sutures are really needed.
 9. Black Mage says:
 "Stopping power" as you imply is represented by kinetic transfer is generally a poor indicator of projectile efficacy. Bullets are lethal because of their mode of injury, specifically: deep tissue damage, CNS damage and rapid exsanguination.
 10. The main advantage of throwing knives in a fight is as suppressing fire. Unless you get lucky and poke someone's eye


Liquid Nitrogen Is Beautiful When It's Dancing Across Gasoline
Instead of mixing, it just spins a beautiful trail of gas.
Amber, Visual arts, Painting, Art paint,
Pouring liquid nitrogen on another liquid won't result in an instant block of ice, nor even a slushie. Ultimately, it'll have very little effect on the liquid below but, as YouTuber carsandwater illustrates, it will look very cool while it is busy having no effect.
In this random but mesmerizing video, you'll see a few spoonfuls of liquid nitrogen dance around on the surface of gasoline, rubbing alcohol, and water.
Because the liquid nitrogen is less dense than the water, it just floats on top instead of mixing in. And while it does, it sometimes forms a tiny bit of ice beneath it, which acts as an insulator and keeps the warm liquid somewhat separate from the cold nitrogen. In the meantime, the liquid nitrogen just floats around, spinning and emitting some really cool vapor shapes as it evaporates.
It's not quite as flashy as using liquid nitrogen to fight against a flamethrower, but it's probably a little safer.

Technical Solution
It's been explained to you that imaging operations on server operating systems and computers that use a hardware RAID array must occur from a 32-bit Windows PE environment where the network interface card (NIC) drivers and mass storage controller drivers are included in that environment. You need to know how to build this Windows PE disk so that you can complete your imaging with the Ghost Cast Server.
The default 16-bit DOS environment that is used on regular Ghost Boot Disks does not correctly interpret hardware RAID arrays or server operating systems.
Symantec Technical Support for Windows PE is limited to the use and troubleshooting of Ghost. Support is not offered for configuring or troubleshooting Windows PE operations outside
the functionality of Ghost. The information below is provided "as is" and questions about Windows PE or the process used to create a Windows PE disk should be directed to Microsoft.
1. Download the Windows Automated Installation Kit (WAIK) located at the following URL:
2. Once you have WAIK download, burn the image file to DVD using 3rd party burning software or extract the contents of the image file to a folder.
3. The following components should be installed on a Windows XPSP2, Windows 2003 SP1, or Windows Vista computer. These components are all available on the WAIK DVD burned in step 2.
a..NET Framework Setup
b. MSXML 6.0 Setup
c. Windows AIK Setup (install last).
4. Click Start > All Programs > Microsoft Windows AIK > Windows PE Tools Command Prompt
5. Type the following commands at the command prompt:
a. copype.cmd x86 c:\winpe_x86
b. imagex /mountrw c:\winpe_x86\winpe.wim 1 c:\winpe_x86\mount
Next, you'll want to copy ghost32.exe, NIC drivers, and Mass Storage Controller Drivers to the PE disk. The NIC drivers and Mass Storage Controller drivers need to be Vista drivers.
c. copy "C:\Program Files\Symantec\Ghost\Ghost32.exe" c:\winpe_x86\mount\windows
d. copy "[NIC driver location]" c:\winpe_x86\mount\windows (Vista Drivers only)
e. copy "[Mass Storage Driver Location]" c:\winpe_x86\mount\windows (Vista Drivers only)
f. peimg /prep c:\winpe_x86\mount\windows

- Bhambhani Y (2002). Physiology of wheelchair racing in athletes with spinal cord injury. Sports Med. 32 (1): 23-51. Summary: Wheelchair racing is one of the most popular sporting activities of individuals with spinal cord injury. Athletes with this impairment have unique changes in metabolic, cardiorespiratory, neuromuscular and thermoregulatory systems, which reduce their overall physiological capacity compared with able-bodied individuals or individuals with other types of impairments. This review on spinal cord injury: presents the International Stoke Mandeville Games Federation classification of wheelchair athletes; describes methods commonly used to characterise anaerobic and aerobic fitness; presents the findings of physiological studies that have evaluated wheelchair racing performance; identifies the risks associated with temperature regulation when competing in wheelchair races; and discusses special conditions that can influence wheelchair racing performance. Currently there is limited research that has examined the relationship between sprint or distance wheelchair racing performance and the anaerobic and aerobic components of physical fitness. Although the descriptive evidence indicates that the profiles of these athletes reflect their training and participation in these specific events, the association between their physiological profiles and real or simulated racing performance is unclear. The generally accepted concept that high values of aerobic and anaerobic power are strongly correlated with endurance and sprint racing performance, respectively, are not necessarily true in this population. Athletes with spinal cord injury have an impaired thermoregulatory capacity, because the compromised autonomic and somatic nervous system functions disrupt control of skin blood flow and sweating below the level of the lesion. As a result, they may be more susceptible to hyperthermia during distance wheelchair racing performance. Wheelchair athletes should follow recommendations advocated for able-bodied individuals to minimise their risks of heat stress during competition. Many athletes with quadriplegia voluntarily induce autonomic dysreflexia (commonly known as boosting) during distance racing events to improve performance. Experimental evidence indicates that boosting can improve performance time by 10% in elite wheelchair marathon racers during simulated racing, as a result of increased oxygen utilisation in the boosted state. However, since boosting can be dangerous to health, the International Paralympic Committee has banned athletes from voluntarily inducing it during competition. The use of anti-gravity suits to increase lower-body positive pressure can increase the peak oxygen uptake, cardiac output and stroke volume. However, the use of abdominal binders does not influence these physiological responses. An effect of either of these techniques on wheelchair racing performance has not been demonstrated.

We all know that women outlive men. But there's some good news for XYs: since the 1970s, the gender gap in life expectancy has shrunk. Now, a study released Monday in Proceedings of the National Academy of Sciences explains a major reason why. Surprisingly, the answer has little to do with eating fewer Big Macs. Since the 1970s, more baby boys are surviving birth in the first place.
The study authors analyzed more than 250 years of mortality data from 15 developed countries. Turns out that in 1751, males were only 10 percent more likely to die at birth than females. But that disadvantage increased until its peak of 30 percent around 1970. Since then, remarkably, it has declined.
Why? First off, males draw the short straw at the start. One reason is that baby boys' immune systems can't thwart infections as well as girls' can. Boys are also more likely to be born premature and suffer early respiratory distress. Their bigger body and head sizes also make them harder to deliver.
Before germ theory took hold in the 1870s, the authors explain, the leading cause of infant death was infectious diseases. As sterile practices and other medical improvements gained traction in the twentieth century, the leading cause of death shifted to childbirth complications. But since the 1970s more babies have been born by C-section, and neonatal ICUs are on the rise. These medical advances are disproportionately helping the more vulnerable males.

The Importance of Caring for Your Grey Duck Down Jacket
Your Grey Duck Down jacket is not just a stylish and functional piece of clothing; it is an investment that requires proper care to maintain its performance and longevity. While these jackets are designed to be durable and provide outstanding insulation, neglecting regular care can significantly impact their effectiveness. By following a few simple maintenance tips, you can keep your Grey Duck Down jacket in top condition and enjoy its warmth for years to come.
Cleaning and Washing Your Grey Duck Down Jacket
Proper cleaning is essential to keep your Grey Duck Down jacket performing at its best. Before washing, always refer to the care instructions provided by the manufacturer to ensure you do not damage the jacket. Most down jackets can be safely cleaned in a washing machine using gentle detergents specifically designed for down-filled products. Avoid using fabric softeners or harsh chemicals, as they can strip the natural oils from the down and reduce its insulating properties.
It is important to note that frequent washing may not be necessary, as down jackets naturally repel dirt and oils. When in doubt, spot cleaning small stains with a mild soap and warm water mixture is a better alternative. If your jacket requires a full wash, set the machine to a gentle cycle and use cold water. Once washed, allow the jacket to air dry thoroughly, avoiding direct sunlight and heat sources as they can cause clumping and damage the down fill.
Storing Your Grey Duck Down Jacket Properly
Proper storage is crucial to maintain the loft and insulation of your Grey Duck Down jacket. When not in use, it is best to store the jacket in a cool, dry place away from direct sunlight. Avoid compressing the jacket for extended periods, as this can lead to loss of loft and affect its insulating capabilities.
To maximize storage space while maintaining the quality of your jacket, use a breathable storage bag or a large pillowcase. Avoid plastic bags, as they can trap moisture and promote the growth of mold or mildew. Additionally, store your down jacket in an area where it is protected from pests and rodents that may chew or damage the fabric.
Tips for Maintaining the Insulation of Your Grey Duck Down Jacket
To preserve the loft and insulation of your Grey Duck Down jacket, follow these tips:
1. Avoid excessive compression: When packing or traveling, try not to crush your down jacket for long periods. Instead, loosely stuff it in a breathable storage bag.
2. Regularly shake and fluff: After unpacking or storing your jacket, give it a gentle shake to distribute the down evenly. Fluff the jacket by hand to restore its loft before wearing.
3. Avoid moisture exposure: Down loses its insulating properties when wet. If your jacket gets wet, dry it promptly to prevent clumping and minimize the risk of mold or mildew.
4. Avoid applying pressure on seams: Excessive pressure on the seams can weaken the stitching and cause down leakage. Be mindful while wearing or packing your jacket.
5. Use a down-specific detergent: When washing your jacket, opt for a down-specific detergent to ensure the soap does not damage the filling. Regular detergents can strip natural oils and negatively impact the down's insulation properties.
Repairing and Restoring Your Grey Duck Down Jacket
Over time, wear and tear can occur, causing small rips, tears, or loss of down feathers in your Grey Duck Down jacket. To extend its lifespan and functionality, it is essential to address these issues promptly. Many manufacturers offer repair services, so consider reaching out to them for professional repairs. However, if you prefer a DIY approach, patching small holes with specialized down repair tape or using a needle and thread can be effective solutions.
For larger repairs or extensive damage, it might be best to consult a professional tailor or send your jacket to a reputable repair center. They can replace zippers, repair seams, and restore any lost insulation, ensuring your jacket remains in top condition.
In conclusion, caring for your Grey Duck Down jacket is vital to preserve its quality and functionality. By following the maintenance tips outlined above, cleaning it properly, storing it correctly, and addressing any repairs promptly, you can enjoy the warmth and comfort of your jacket for many outdoor adventures to come. Remember, a well-maintained down jacket will not only keep you snug but also protect your investment in this valuable piece of outerwear..


Clay From Clothes
Here is a question submitted by Kelly:
I am having trouble getting clay out of my sons white baseball uniform.
Tools & Technique:
1. Carefully remove whatever you can using a soft scraping tool(spoon).
2. Soak and agitate in water before washing to further remove clay.
3. Use a laundry pre-treat or liquid detergent and rub into stain.
4. Launder as usual.
For tough stains use digestant presoak (don't use on wool or silk) product for about 30 minutes. Soak old stains for at least several hours.
Launder normally, rinse, and inspect. If stain remains, soak an additional 30 minutes, then rewash. If you are still having trouble try using a laundery booster available at most grocery stores. If the shirt is white you could also try bleaching the stains, by adding blech the the wash water.
Precaution:Always read and follow the care instructions and any warnings on the garment label. Don't dry the clothes until you have inspected the stain to see if it is gone. Heat sets most stains.

Local positioning system
A local positioning system (LPS) is a navigation system that provides location information in all weather, anywhere within the coverage of the network, where there is an unobstructed line of sight to three or more signaling beacons of which the exact position on earth is known. A special type of LPS is the Real-time locating system; which also allows real-time tracking of an object or person in a confined area such as a building.
Unlike GPS or other global navigation satellite systems, local positioning systems don't provide global coverage. Instead, they use (a set of) beacons which have a limited range, hence requiring the user to be near these. Beacons include cellular base stations, Wi-Fi access points, and radio broadcast towers.
Nowadays, local positioning systems are often used as complementary (and in some cases alternative) positioning technology to GPS, especially in areas where GPS does not reach or is weak, for example, inside buildings, or urban canyons. Local positioning using cellular and broadcast towers can be used on cell phones that do not have a GPS receiver. Even if the phone has a GPS receiver, battery life will be extended if cell tower location accuracy is sufficient.
An LPS can use any of the following to calculate the position of an object:
- Indoor positioning system
- Hybrid positioning system
- Real-time locating system
- Mobile phone tracking

Developing leaders for a diverse democracy is an increasingly important aim of higher education and social justice is ever more a goal of leadership education efforts. Accordingly, it is important to explore how dominant leadership models, as blueprints for student leadership development, account for and may unwittingly reinforce systems of domination, like racism. This critical discourse analysis, rooted in racialization and color-evasiveness, examines three prominent college student leadership development models to examine how leaders and leadership are racialized. We find that all three leadership texts frame leaders and leadership in color-evasive ways. Specifically, the texts' discourses reveal three mechanisms for evading race in leadership: focusing on individual identities, emphasizing universality, and centering collaboration. Implications for race in leadership development, the social construction of leadership more broadly, and future scholarship are discussed.

When is an owlet not an owlet but really an owl? When it's an Asian barred owlet (or other species of owlets, of course). Learn more about this small but fierce owl!
Asian Barred Owlet Fun Facts
- The Asian barred owlet (Taenioglaux cuculoides) is one of 14 owl species with the official "owlet" name, all of which are part of the Strigidae family. The word owlet is also used to refer to baby owls of any owl species.
- Within their large range, these birds have several different common names, including barred owlet, cuckoo owl, and cuckoo owlet. Because these names are so general, however, it is best to refer to the bird's scientific name when identifying it so there is no confusion about which species is which.
- While small at just 9-10 inches long, these owls are still fierce hunters and prey on insects, lizards, amphibians, small mammals, and even small birds. They may even catch small birds or bats in flight.
- There are 5-8 subspecies of Asian barred owlet that vary in overall range and subtle plumage color differences. As studies continue about these birds, it is possible the subspecies may be split into different distinct owlet species.
- Unlike many owls, the Asian barred owlet is most active hunting during the day, when its preferred insect prey is also more active and easily captured. This owl is also often heard as part of the dawn chorus.
- When agitated, this owlet will slowly sway or wag its tail from side to side, creating a threatening display intended to ward off intruders. This behavior is quite distinctive and can help identify the bird.
- The Asian barred owlet was featured on a 2014 collectible postage stamp in Mozambique. The stamp was issued for 175 meticals (the local currency of Mozambique), which was roughly equivalent to $5.80 USD (at the time of the stamp's issue).
Adding the Asian Barred Owlet to Your Life List
Most owls can be challenging to add to your life list, and while the Asian barred owlet is considered relatively common in its range from China and southeast Asia into the Himalayan Mountains in northeastern Pakistan, they can still be difficult to find. In some cases, they may be found in gardens and parks, and contacting a local birding group or experienced guide can be a good way to locate an easier-to-see Asian barred owlet. These birds are more common at higher elevations with extensive pine forests and evergreen jungles, but owling trips should be carefully planned for safety. It is helpful that this owl is largely diurnal and hunts during the day, making it somewhat easier to see than more nocturnal owls.

data from experimental models for each of seven key operating
1. Specimen preparation
2. Bacterial concentration and surface immobilization
3. Bacterial viability after immobilization
4. Species immuno-identification
5. Quantitative growth rate measurement
6. Growth rate comparability to standard methods
7. Quantitative antibiotic kill rate measurement.
The conference was sponsored by the American Association for Clinical
Chemistry (AACC, _URL_). The AACC is a large, US-based international
scientific/medical society of clinical laboratory professionals,
physicians, research scientists and other individuals engaged in
science-related clinical laboratory disciplines. The Oak Ridge Conference
is the AACC venue for new science and technology in emerging diagnostics.
The poster presentation represents the company's first disclosure of
Quantum Microbiology principles to the scientific and clinical laboratory
communities. According to David Howson, Accelr8's president, "this research
shows that our methods produce results comparable to those from standard
methods, but in a much shorter time. The time to results are well within
our stated goals of two hours for identification and counts, and eight
hours for testing antibiotic resistance. Under favorable conditions,
standard methods require at least 24 hours."
The reported research used standard bacterial reference strains and
studied each step in the analytical process. "Our next steps include
integrating all of the analytical steps into a single continuous
procedure," Howson continued. "We also will also proceed to studies using
known concentrations of bacteria in biological fluids. These studies will
help to demonstrate our ability to eliminate culturing and isolation, and
analyze bacteria extracted directly from a specimen."
In May, the company will present a poster at the General Meeting of the
American Society for Microbiology (ASM, _URL_). The ASM is the
leading American professional society for microbiologists. The poster will
studies on a challenging type of antibiotic resistance analysis that
has proven difficult to implement in standard automated systems.
"These presentations are the first in our planned pipeline of
scientific and clinical publications," added Howson. "Hospital-acquired
pneumonia is the number one infectious cause of mortality in the ICU. Rapid
antibiotic resistance analysis would represent a breakthrough in addressing
this problem. We intend ultimately to validate the BACcelr8r as achieving
this analytical goal, and these presentations offer the first evidence that
this will be possible."

Activities will help students:
- Practice critical reading skills.
- Use expressive oral language to stand up against prejudice.
- Practice metacognitive reading strategies in viewing advertisements.
- What biases do advertisements most commonly perpetuate?
- What happens in our own minds when we see and hear these biases on a constant basis?
- How can we prevent the biases in ads from affecting the way we think and feel about ourselves and others?
- Have the
students collectively view the advertisement below or a similar advertisement
that perpetuates stereotypes. The advertisement here perpetuates the idea that
girls should look a certain way, that girls care primarily about their
appearances and are somewhat ditzy, that it is "cool" to be a fake sort of
tough, etc. Guide students to use critical reading strategies developed in lesson
two to analyze the advertisement.
- Explain to students that, as they have seen over the course of this series, some advertisements are full of biases. They perpetuate stereotypes, use unfair representations, and teach unjust ideas about how people are and how people should be.
- Ask students to talk with a partner about what goes through their minds when they see an advertisement. Encourage them to be as honest as possible: Maybe the first thing they think of is whether or not they want the product being sold. Have them be really specific in explaining what they think and how the advertisements affect them.
- Then tell students that their task is to come up with a list of three to five techniques for "reading" an advertisement such as the one presented in this lesson without letting its biased messages influence them. In other words, since we cannot avoid, how can we work to minimize their impact on our self-esteem and the way we view others different from ourselves? Explain to students that there is no right or wrong here, but they should think of what strategies would be genuinely effective. Students may work independently, in partnership or as a group, depending on the needs of the class.
- After students have developed their lists, publish them and display them prominently. Encourage other students to read the lists and practice putting the strategies into action!
The real test of the strategies students come up with is whether they work outside the classroom. Give students photocopies of their lists to take home and post in their rooms or elsewhere in their homes. Challenge them to put the strategies into action over the course of the week. Then give them a chance to report back on whether and how the experience has changed the way they look at advertisements.


Soft Bipolar Disorder Cyclothymia Issues: Living Against the Clock; Does Loss of Daily Rhythms Cause Obesity?
Daily or "circadian" rhythms including the sleep wake cycle, and rhythms in hormone release are controlled by a molecular clock that is present in every cell of the human body. This human clock has its own inbuilt, default rhythm of almost exactly 24 hours that allows it to stay finely tuned to the daily cycle generated by the rotation of Earth. This beautiful symmetry between the human clock and the daily cycle of Earth's rotation is disrupted by exposure to artificial light cycles, and by irregular meal, work and sleep times. This mismatch between the natural circadian rhythms of our bodies and the environment is called "circadian desynchrony."

If you have
diabetes and low blood sugar and you drive, your
ability to steer the car may be affected. You also could behave aggressively or
appear to be drunk if your blood sugar gets very low.
There is no
reason why people with diabetes should not be allowed to drive. But you
should take the following precautions:
Wear medical identification at all times. In an
emergency, medical identification will let people know how to care for you.
Talk with your doctor or pharmacist about how to get medical identification.
Carry some quick-sugar foods with you at
all times. These include raisins, hard candy, or fruit juice. Keep some in your
car in case you have low blood sugar while driving and need to stop and eat
Plan your trips so that you will not miss or delay a
meal, if possible. If a trip will delay a meal, eat a snack before
Always have your home blood sugar meter with you, and
check your blood sugar level if you think it may be low. If you have low blood
sugar often or you do not get the usual symptoms of it, test your blood sugar
before you drive. Consider having someone else drive.
blood sugar is below 70 mg/dL before you drive, do not drive until you have
eaten something to raise it. Before driving, check to make sure it has risen to
your target range.

its 9600 bytes. as the voice frequency irange is in between 16-20,so sampling frequency must be grater than 40hz,so number of samples in 4min=40*240=9600 samples hemce we need a memory of 9600 bytes to store the voice signal

Its just 1440 bytes. Bandpass sampling frequency is just 6Hz. so just 6*240 bytes.

since the signal is in the band 16-20 HZ. bandwidth is 4HZ and so 8HZ sampling rate enough..i.e 8 s/sec. 4min=240sec.
4min duration has 8*240 samples
and each sample has 8 bits,so min required memory is 8*8*240=1920 bytes

It's 1920Bytes. As the bandwidth (f2-f1) is 20-16=4Hz. The sampling frequency should be twice the bandwidth (2B). the sampling frequency is 8Hz= 8 samples= 8 cycles/second.
4 minutes=(4*60) =240 Seconds
1sample->1 Byte
1Second->8 Samples
240 Seconds->(240*8) = 1920 Samples

Two things i wish to point here.
1) They have said that they are representing each sample by 8 bits. which implies that the sampling frequency is quite high. and that for one cycle of the minimum freq we get 256 samples.
2) Regarding the criterion that the sampling frequency should be twice of the bandwidth. this is applicable only when we are dealing with base band signal. whereas here it is pass band (since 16 to 20 is significant in our case).
So the sampling frequency should be quite high considering the two facts.
 Was this answer useful? Yes
 - Jul 12th, 2007
Nyquist–Shannon sampling theorem states that perfect reconstruction of a signal is possible when the sampling frequency is greater than twice the maximum frequency of the signal being sampled...so imagine sampling a 16Hz signal with 8hz...there's gonna be a sample every 2 cycles!..it has to be 40
 Was this answer useful? Yes
 - Aug 17th, 2008
Voice sample = 8 bit
Smaple frequency = 1/20 s = 0.05s
for 4 minutes = 4*60(minto sec)/0.05 = 4800 sample
s0 total memory = 8 * 4800 = 38400 bits = 4800 Bytes = 4.69 KB
 Was this answer useful? Yes
 - Aug 28th, 2008
banwidth of signal=4Hz
according to niquist theorem sampling frequency>=2*bandwidth
so sampling freq=2*4Hz(8 samples /sec)
1 samples is stored as 1 byte
so 8*8 bits/sec
so for 4 mins bits are = (4*60)*(64)=15KB
so asn is 15 KB.

Voice signal is sampled at 8000 samples per second. (Human voice is in the range of 300Hz-3400Hz, and according to nyquist sampling rate we take it more than double the rate).

2005 HSR&D National Meeting Abstract
3001 — Enhancing Performance Monitoring: What Can We Learn from Physician Explanations of Poor Care?
Hogan MM (VA Ann Arbor Healthcare System)
Kerr EA (VA Ann Arbor Healthcare System)
Hofer TP (VA Ann Arbor Healthcare System)
Hayward RA (VA Ann Arbor Healthcare System)
Asch SM (Greater LA Healthcare System)
Standard performance monitoring in VA and managed care relies on explicit assessments using a guideline-based checklist approach for a limited number of conditions and measures. Using physician structured implicit review (SIR) we compared physician's explanations for poor care with three explicit performance measurement systems to identify areas where explicit performance monitoring can be enhanced.
We sampled 621 veterans with at least two visits in each of two years in two VHA regions, oversampling for diabetes and COPD. The sample was 97% male with a mean age of 62. Twelve physicians reviewed medical records used an SIR instrument and explained poor care ratings. Poor care explanations were matched to indicators in three explicit systems; QA Tools, with 30 conditions and over 400 indicators, VA External Peer Review Program (EPRP) and the Health Plan Data and Information Set (HEDIS), each with fewer conditions and indicators.
Overall, 54% of the 2480 explanations matched indicators in any of the explicit systems. Matches varied by explicit system (QA Tools, 49.9%, EPRP, 39%, HEDIS, 13.6%) and by condition (prevention, 82.8%; diabetes, 59.2%; hypertension, 41.9%; COPD, 37.3%; other chronic conditions 28.5%). We further examined matching and non-matching explanations. For example, for diabetes there were 239 explanations of poor care that matched physician explanations, and 75% (179) were accounted for by four commonly measured items: renal evaluation (N=46), foot exams (N=46), eye exams (N=45), and A1c monitoring (N=42). Among non-matching diabetes explanations (N=165), the most common were failure to change medications in response to the patient's condition (e.g., elevated A1c) (24%, N=40), failure to work up abnormal test results (15%, N=24), and other ongoing assessment (13%, N=22).
Explanations were more likely to match explicit indicators for conditions with good evidence and commonly used standards, e.g., prevention and diabetes. Explanations for poor care were frequently not covered in any of three explicit measurement systems.
Explicit performance monitoring has the advantages of being readily understood and informing health systems about specific areas for quality improvement. Implicit reviews offer opportunities to identify potential new indicators for inclusion in explicit performance monitoring.

BSE in Northern Ireland: epidemiological patterns past, present and future.
Ferguson NM., Ghani AC., Donnelly CA., Denny GO., Anderson RM.
By 30 January 1998, there had been 170,259 confirmed cases of BSE in Great Britain (GB), 1766 confirmed cases in Northern Ireland (NI) (2 January 1998), and 276 confirmed cases in the Republic of Ireland (31 January 1998). Analysis of the epidemiological patterns in the NI epidemic reveals significant clustering of cases in herds and counties. The observed clustering of cases within herds results in lower per capita incidence of BSE in previously unaffected herds, providing support for the introduction of a certified herd scheme in NI. By fitting a backcalculation model to the case data, we can estimate the number of animals infected with the aetiological agent of BSE and project the number of future cases. We predict that the epidemic will decline rapidly, with approximately 99 cases (95% confidence interval 30,504) occurring in the five year period _PHONE_.

The Baalands flock consists of 38 purebred and crossbred
Katahdin ewes. For the 2013 lamb crop, three rams were used for breeding: a purebred registered Katahdin yearling ram (Phelps) from Triple L Farms (Virginia); a 5/8 Lacaune x 3/8 Katahdin ram lamb (Spooner) from the Spooner Agricultural Research Center (Wisconsin); and a 1/2 Katahdin x 1/4 Hampshire x 1/4 Suffolk yearling ram (B-Ears). The purpose of the current breeding program is to produce purebred registered Katahdins, as well as crossbred lambs of two specific types: Katahdin "Mule" (3/4 Katahdin x 1/4 Blackface) and Katahdin "Dairy" (11/16 Katahdin x 5/16 Lacaune).
The Baalands is a performance-oriented flock, specializing
in the production of replacement ewe lambs and maternal sires. Selection
is on the basis of maternal traits: fertility, prolificacy,
mothering ability, milk production, udder conformation, longevity, and easy-care
(no shearing, good fleshing, minimal deworming, and minimal hoof trimming).
The goal of the Baalands is to raise Katahdins and their crosses for use in profit-oriented sheep enterprises.
Lambs are born in February, March and April and ready to go in June and July. Purebred and crossbred lambs are available. Ram lambs are genotyped for scrapie resistance. Sometimes, a few mature ewes are available for sale after weaning.
Why Katahdins? Katahdins are a medium-sized hair (shedding) sheep developed
in the United States (Maine) in the 1950's. They do not require shearing,
crutching, or tail docking. They are more resistant to internal
parasites (worms) than conventional wooled breeds. Katahdins
excel in reproductive performance, typically producing lamb
crops in excess of 200 percent. They can be crossed with rams
of any breed to produce replacement ewe lambs and market lambs of the desired type.

Griffiths' explanation of degenerate perturbation theory
 1. Hi all.
 I'm reading about time-independent perturbation theory for degenerate states in Griffiths' Introduction to QM.
 I have a question on the things he writes in chapter 6.2, page 269. What does he mean by the so-called "good" linear combinations?
 I hope you can shed some light on this. Thanks in advance.
 Best regards,
 2. jcsd
 3. Can I get a moderator to move this thread to the homework section, preferably the "Advanced Physics"-section? Thanks in advance.
 4. Ok, this is as far as I've come.
 We want W to be a diagonal matrix, because then we can solve the problem just like we would solve the unpertubated problem. But in order for W to be a diagonal matrix, we would have to write it in the basis spanned by its eigenvectors.
 Normally, W is given in the basis of H0, i.e. the space spanned by the unpertubated wave functions.
 And this is where I can't go any further.
 5. i started writing a response to this yesterday and quit half way because though i've just suffered through trying to interpret griffith on this as well i still don't get it.
 here's what i got:
 when we write down the matrix representation of H' in the eigenbasis of H0 it's not diagonal, like H0 is in its eigenbasis. but we don't need it to be if the eigensystem of H0 isn't degenerate, the eigenvalues are distinct. perturbation theory still works. if the eigensystem of H0 is degenerate then perturbation theory breaks down, ( in the denominator of some of the terms where there's a difference, a minus sign ).
 what the breakdown actually is is a zero in the denominator which is an infinity. it occurs when you consider two different eigenstates in that same degenerate part of the eigenbasis, therefore they have the same energy eigenvalue but different wavefunctions. these are of the off diagonal part of the matrix representation of H'. we fix this break down making the numerator zero, on the occasion that the denominator is zero. this equates to making the off diagonals zero which itself equates to making the basis in which H' is represented orthogonal. this is diagonalization.
 i doubt that helps but post some response question and maybe we can figure it out together.
 the whole argument about good and bad combinations i don't understand though what he means by 'good' combinations are the new diagonalized eigenstates in that degenerate subspace.
 6. First, thanks for replying. It is very comforting to know that there are other people who believe that this part of Griffiths' book is poorly written.
 Try and take a look at this thread (especially posts 3 and 4):
 What it all boils down to is that we wish to be able to use non-degenerate perturbation theory: But in order to do this, the W-matrix has to be diagonal (that's what Griffiths concludes on page 271). W is a diagonal matrix when it is expressed in its eigenspace, and to find this diagonal matrix, we must find the eigenvectors of W and use:
 Mdiagonal matrix = S-1eigenvectors * W * Seigenvectors.
 When we have the W-matrix in this form, we can go ahead and use: <\psi_i |H'| \psi_i>, where \psi_i are the eigenvectors of H0 as expressed in the eigenspace of W. But in Griffiths' example, he does not use this approach, rather he just goes ahead and finds the eigenvectors and their corresponding eigenvalues of W in the eigenspace of H0. This is where I cannot interpret Griffiths' procedure anymore. I'm not sure where to go from here. Does the above thread give you any ideas?
 Best regards,
 Last edited: Feb 5, 2009
 7. well the eigenvalues you compute end up being <\psi_i |H'| \psi_i> in the diagonalized basis of W, i mean they're constructed as such. is that what you're having a problem with? what exactly don't you understand about his prescription? the stuff about the commuting operator? that's just the change of basis operator which i can say with a cavalier attitude but don't expect me to guess the eigensystem just by looking at the symmetries of the system, which is what i think my professor expects from us.
 8. That is what I do not understand. I believe that above statement is only true if \psi_i are the basisvectors of the eigenspace of H' (and thus W), but they are not. They are the basisvectors of H0.
 9. no they're not, they're linear combinations of the basis vectors of H0.
 that cleared up for me my last concern. thanks.

 10. I'm glad to hear that.
 The wavefunctions \psi0i that we use to find the first order corrections are eigenfunctions of H0. This is on page 269 (the beginning of the subsection).
 11. yes but the one we are considering is [itex]\psi^0 = \alpha \psi_a^0 + \beta \psi_b^0 [/itex]
 where [itex] \psi_a^0 [/itex] and [itex] \psi_b^0 [/itex] are eigenfunctions of H0
 hopefully you're referring to what i think you are, eqns 6.16-6.18 in 6.3. my pages are numbered different from yours.
 12. Yeah, the pages are numbered differently then. But we agree: It is a linear combination.
 Ok, I think I should take this from the top. I think I am confusing myself.
 We know that [itex]<\psi_i |H'| \psi_i>[/itex] will give us the eigenvalues of W when both H' (i.e. W) and [itex]\psi_i[/itex] are given in the eigenspace of W. But [itex]\psi_i[/itex] is given in the basis of H0, since it is a linear combination: [itex]
 Now H and [itex]
 [/itex] must be in the same basis. Which one do we choose?
 This is my problem.
 13. you are confusing yourself
 this is true
 from here on you lose me
 you're over complicating things. here's the prescription
 we have perturbation theory
 it doesn't work when the eigensystem of the unperturbed hamiltonian has a degenerate subspace
 in a degenerate subspace of an eigenspace linear combinations of vectors are also eigenvectors:
 if x and y are eigenvectors of A with eigenvalue z, for both then A(2x+3y)=A3x + A2y = 3Ax+2Ay = 3zx+2zy = z(3x+2y)
 hence we are allowed to choose any linear combination of vectors in that subspace when we do w/e we want with it. hence we can choose such a combination of the original eigenfunctions that diagonalizes H' which allows regular perturbation thry to work again.
 so we diagonalize H' and apply perturbation theory but when you do that you're doing
 [itex]<\psi^0|H'|\psi^0> [/itex] where now [itex]\psi_0 = \alpha \psi_a^0 + \beta \psi_b^0 [/itex] but that's an eigenstate of H' and hence you get it's eigenvalue which you already calculated.
 there's two different diagonalization floating around here. H0 is diagonal in it's own eigenbasis representation. H' a priori isn't diagonal in that same basis, nor does it need to be because vanilla perturbation theory doesn't need H' to be diagonal but vanilla perturbation does need the eigenfunctions of the unperturbed hamiltonian. the point here is that a linear combination of eigenfunction in a degenerate subspace are still eigenfunctions and therefore all the stuff they derived in terms of them still works, just that now it doesn't blow up around H' too.
 Last edited: Feb 5, 2009
 14. I assume you mean "degenerate perturbation theory" when you say "vanilla perturbation theory"? Nonetheless, thank you for your description. I can see that I was on the right track before, but I was over-complicating stuff.
 Now only one question remains, which is quite important actually: How are we sure that there will always exist a linear combination of eigenstates of H0 that can diagonalize H'?
 Last edited: Feb 6, 2009
 15. cause you can. cause what you're actually doing is orthonormalizing the basis for the degenerate eigenspace which you can always do. there are in fact several algorithms for it. more on this later
 16. Ok, I will look forward to
