Launching a Diversity Bank

We will soon be launching a Diversity Bank that is intended to put scientists of all ethnicities, at various levels, in various institutions, in touch with one another and with funding and research opportunities. We are also hoping to build on a successful program to bring underrepresented minority scholars and those who work with and educate them to the society’s annual meeting, among many other initiatives intended to raise awareness of plant biology among minority scientists.

Beyond efforts to bolster participation by underrepresented groups, ASPB–again, along with many sibling organizations–does a great deal more to foster a sense of community, and the society’s leadership is working hard to ensure that up-and-coming plant biologists–students and postdocs–are included in that community. For example, ASPB offers career development workshops at each of its annual meetings, and we are working on creating a facsimile of the Howard Hughes Medical Institute/Burroughs Wellcome Fund lab management course. magnets for sale course will be offered next year. And to highlight the diversity of careers pursued by plant biologists, Plant Physiology, one of the two journals published by ASPB, recently published a series of essays entitled “Why We Do What We Do: Plant Biologists Discuss Their Career Choices.” These essays are available to all.

ASPB recognizes that it needs to continuously rejuvenate itself to thrive as a membership organization. We are working to engage students and postdocs in a number of ways, including placing a student and a postdoc on magnets for sale regular membership committee and offering strong Neodymium magnets prizes and awards targeted directly to early-career scientists. ( samarium cobalt magnets year, both Shin-ya Miyagishima and Krishna Niyogi–two of the scientists profiled in this feature–received ASPB awards targeted, respectively, to postdocs and junior faculty.) And alone or in partnership with sibling organizations, such as the Botanical Society of America, ASPB is making strenuous efforts to nurture the roots of the career tree through public outreach and by engaging schoolteachers.

In all of these venues–and during the society’s annual meeting, which more than 1500 plant biologists typically attend–the focus is on establishing, developing, and nurturing professional networks. This function is by no means unique to ASPB; indeed, along with journal publishing, it is the raison d’être of most membership organizations. So, whether y magnets for sale career objective is to remain within the discipline in which you are currently working or studying, to switch research fields, or to pursue professional advancement in another realm altogether, I urge you to consider joining and making use of y magnets for sale membership in “your” professional organization. [Editor’s Note: And please keep in mind that if you’re a scientist of any sort, AAAS is y magnets for sale professional organization, or one of them.]

It worked for me. As a graduate student I was a member of ASPB, and through the connections I made in the organization (and the opportunity to present my thesis work in a “short talk” at an ASPB annual meeting many years back) I found a tremendous postdoc adviser and lab. After leaving that lab to take my first job in scientific writing and editing (a decision that was informed by networking contacts kindly furnished by my postdoc adviser), I joined the Council of Science Editors, through which I learned a great deal more about the profession–and made a number of what turned out to be extremely useful networking contacts, as well as a good number of friends. In my current position, I’ve joined a professional organization for society executives (yep–there’s one for folks like us, too!), and, once again, I’m establishing useful and interesting contacts and also making friends.

Thanks for listening.

Science Careers in the Limelight

On Thursday, strong Neodymium magnets York Times columnist David Brooks took up the theme of science careers, arguing that the oft-lamented shortage of scientists and engineers is “much overblown,” and that America’s eclipse by India and China is far from inevitable–in large part because the United States leads the world in investment in science and technology. Brooks cites FONW (Friend of Next Wave) Michael Teitelbaum of the Sloan Foundation in arguing that there is no shortage of scientific labor in America. At least he got that part right.

Samarium Cobalt Was the First Rare Earth Permanent Magnet

Fully dense means there is no dilution effect from a non-magnetic phase.
The highest output is available from NdFeB. However, as we will see later, other
application requirements may suggest using slightly less powerful SmCo magnets.

Injection molded magnets suffer from the greatest dilution effect. However, their shape and magnetic pole configuration possibilities often make them the most desireable choice. Tight tolerances are a result of molding to die dimensions – – secondary finishing operations are almost never required. Furthermore, assembly can be simplified through the use of insert-, over-, or multicomponent injection molding.

Compression bonded magnets represent a compromise of sorts between fully dense
and injection molded magnets. The volumetric loading of magnetic phase is greater
than injeConsidering our choices by material, NdFeB represents the highest magnetic output
material up to about 150 degrees centigrade.
It is limited to use above about 135 K (-138ºC), due to a change in magnetic
alignment at that temperature. But from 135 K to about 150º centigrade, it provides
excellent output.

complexity over sintered magnets.
Perhaps the greatest advantage is that thin wall cylinder magnets can be
manufactured using compression bonding. Thin wall rings or cylinders are not
practical with the sintering process due to warpage during sintering and breakage
during grinding.
Except in the pressing direction which varies with die fill and press set-up,
dimensions are very tight, conforming to the tooling dimensions of the die.

Samarium Cobalt was the first widely used rare earth permanent magnet type, starting with the 1-5 composition in the early ’70s and switching mostly to the 2-17 type in the 1990s. When rare earth ore is mined, all the rare earths become available in the refining process, including cerium, lanthanum, misch metal (a combination of rare earths), praeseodymium, neodymium, dysprosium and samarium. As NdFeB usage goes up, more samarium is also mined and available for magnet production. The biggest advantage of SmCo over NdFeB is that of temperature stability.

Ferrite is the Rodney Dangerfield of permanent magnets. We use it in vast quantities and treat it (without respect) like the “rust” it is – – special rust to be sure, but… First commercially available in 1961, it is still used in greater quantity by weight than any of the other materials, primarily due to its very low cost.

How does an engineer start the process of selecting a magnet?
Most start by ruling out magnets that cannot be used due to one or another limitation
such as temperature, magnetic output or material cost.
Temperature and cost are probably the two predominant selection criteria. Device
size and weight are used in the final decision.
We will see later in this talk that magnet material, size/weight and system cost are
all interrelated.

Before we launch into a discussion on the three highlighted items from the last slide, it is appropriate to focus on a problem endemic in the industry: underspecifying the magnet. It is essential for the design engineer, purchasing personnel and manufacturer /supplier to agree to a specification that includes everything necessary to ensure proper device function over the design life. The list above should be considered as the bare minimum and can serve to initiate dialogue and agreement amoung the parties.

Most of you are probably familiar with reversible temperature coefficients – – the amount to which the magnetic output changes as a function of temperature. There are two coefficients: one for Br (induction) and one for Hci (intrinsic coercivity). Ferrite is shown here because, unlike rare earths magnets, ferrite (intrinsic) coercivity increases as temperature increases. Conversely, as temperature drops, coercivity becomes less. Where rare earth magnets have a practical upper use temperature limit, ferrite has a lower use limit. A practical lower use temperature limit is –40 degrees centigrade. Below -40, there is substantial risk of demagnetization. Changes in Br (induction) are greater than with NdFeB or SmCo. For that reason, ferrite is seldom used in sensor applications. However, it is widely used in motors. In the range 0 to 135 K (-138ºC), SmCo is the material of choice. Between 135 K and –40ºC, NdFeB is preferred. Over 180º and up to 250ºC both SmCo and ferrite are usable. Above 250ºC and up to 550ºC, SmCo is preferred. Between –40 and 180ºC, we have other trade-offs that dictate which of the three materials is best. Bonded magnets are generally limited to the range of –40 to 200ºC.

This chart, from a poster presentation in 1999 by Christina Chen of EEC, dramatically shows the change in energy product (BHmax) as a function of temperature. Because SmCo is more temperature stable than NdFeB, NdFeB drops below the output of SmCo, by ~150ºC. Indeed, the higher temperature grade of NdFeB is no stronger than SmCo even at room temperature.

Thus, where the magnet is subjected to high temperatures, especially where demagnetizing stress is expected, SmCo may be preferred.

Grade designations are shown on the plot at the approximate location to denote
representative Br and Hci. Note the compromise between intrinsic coercivity and
Maximum Energy Product.
The maximum recommended use temperature follows with coercivity:
No suffix – – 80ºC maximum
M – – 100º
H – – 120º
SH – – 150º
UH – – 180º
EH – – 200º
Just because a magnet “can” be used at this high a temperature, does not mean it
will function well in the application. Other considerations include operating slope
(permeance coefficient or load line) and demagnetizing stress.
Minimizing irreversible loss also requires a true “square loop” – – not one with a
drooping or irregular intrinsic curve.

We mentioned that almost all NdFeB is today coming from China.
• China possesses at least 75% of the world’s proven reserves of rare earth ore
• Manufacturing costs are approximately 1/15 that of the Western world
Prices have been driven down to-date not because Chinese manufacturers are
competing with US or European companies, but because the Chinese manufacturers
are competing against each other for the Western market.
This has forced major changes in the supply of magnets and magnetic assemblies.
But difficulties remain in sourcing from the Far East that are best served by
companies experienced in trading with China.

The US International Trade Commission maintains information on imports of two categories of permanent magnets (into the US): • Magnets made from metal (8505.1100) such as Alnico, SmCo and NdFeB • Magnets made Other than of metal (8505.1900) such as ferrite Note that the Dominican Republic and Canada are not manufacturing ferrite magnets, but are acting as a pass-through into the US marketplace, possibly to avoid tariffs. China is by far, the largest foreign source of ferrite magnets, especially when the pass-through amounts are considered

This table shows the dramatic increase of importation of permanent magnets, especially NdFeB, rising from $95 million in 1998 to $182 million in 2002. The total for 2003 appears as though it may be considerably lower. Is that because the assemblies containing magnets are now made overseas? As in the previous slide, we see significant imports from Mexico, Japan and China. Since there is no manufacture of NdFeB in Mexico outside of Magnequench, one presumes most of this is a pass-through from China

Even the IT industry benefits from neodymium magnets in making computer hard drives, telephonic applications, television, video applications, and chip detectors. Companies that build generators rely heavily on neodymium to manufacture strong generators. The strength of generators depends on the power of the magnets used.

Manufacturers of oil filters use magnets so that the filters effective separate any iron fillings or other metal chips from the oil. Devices such as metal detectors contain the rare earth magnet.

Machines use them to hold down tarps to cover machinery and cars. You can use them also for making tool belts or for making the doll hold on to its pacifier. Designers for fashion accessories use neodymium magnets for making earrings and jewelry clasps. If you are looking for a magnet to keep name tags in place without having to stitch them on, you can rely on magnets.

Rare earth neodymium is used in the health industry, for alleviating symptoms and relieving pain caused by health issues like arthritis. These permanent magnets have healing abilities and are often called healing magnets.

They are also used in manufacturing Magnetic Resonance Imaging scanning machines. During space flights, NASA uses these rare earth magnets so astronauts can maintain muscle tone.

They are used for experimentation and research purposes. Neodymium magnets are small in size but enormous in its strength, making it convenient to carry anywhere and anytime. Also, because of its small size, toy industries use this magnet to make kid and adult’s toys.

There are many characteristics of neodymium to differentiate it from other magnets. It has a remarkably high resistance to demagnetization thanks to its natural attribute of being the strongest permanent magnet. Unlike the other types of magnet, the rare earth neodymium is affordable. There are two reasons why so many industries use this magnet.

Neodymium magnets require low working temperature for heat applications. If the temperature is set to high degree, they can easily catch fire. Neodymium inspired new applications in areas where magnets were not used.

You may or may not be surprised to learn that if you’re looking at magnets, you’re not alone. The use of magnets worldwide is highly popular. In fact, it’s been estimated that over 120 million people use magnets worldwide. But even so, you may not have been exposed to certain information about this treatment. Here are 7 things you probably didn’t know about magnetic therapy for pain or other ailments.

  1. It is a known fact that magnetic fields affect living tissue, despite some mistaken claims to the contrary. Certain types of mental illness are treated with pulsed magnetic fields. Researchers at Yale have shown that this treatment reduces the “voices” that schizophrenics hear in their heads.
  2. For many years, Tibetan monks have used static magnets to relieve depression. We now know that pulsating magnetic fields can relieve severe depression. According to researchers, pulsed magnetic fields affect cells deep inside the brain. Many who wear magnetic jewelry claim a renewed sense of well-being.
  3. Pulsed magnetic fields alter bones and tissue, and they are used to treat slow-healing fractures, knee pain, neck pain, and even muscle tears.
  4. In Japan, studies have shown that static magnets help to relieve pain in the neck and shoulders. The Japanese have been using magnets for generations, and one out of every eight Japanese sleeps on a magnetic bed.
  5. After a personal experience with magnets, Dr. Ronald Lawrence began doing studies on his patients. Dr. Lawrence used magnets to treat carpal tunnel syndrome. In a 22 patient study, 91 percent showed improvement when using magnets for carpal tunnel syndrome.
  6. In 1999, researchers at New York Medical College discovered that magnets were effective on nine out of 10 diabetic patients with nerve pain. Since the results of those with the fake magnets were significantly worse, the researchers recommended magnets for all patients with nerve pain.
  7. For many years, Vanderbilt neurologist Dr. Robert Holcombe used static magnets to relieve back pain. He said that the pain relief from magnets can be as effective as a shot of morphine.

As evidenced by studies from around the world, as well as anecdotal reports, magnetic therapy can help with many conditions. These conditions include high blood pressure, back pain, peripheral neuropathy, neck and shoulder pain, accelerated wound healing, and even reducing the side effects of chemotherapy.

The most popular application by far for magnetic therapy as a self-treatment is for pain relief, and magnets continue to gain popularity in the United States. As Dr. Dr. Michael Breen pointed out in an article in the Chicago Sun-Times in 2000, magnets are in wide spread usage in many cultures. This a testament to their effectiveness.

Kurt Schmitt writes for http://www.magnetic-jewelry-connection.com where you’ll find at least three more things you didn’t know about magnetic therapy for pain, and magnetic jewelry.

 

super strong magnets

Summer, fall, winter or spring, if you have young children with time on their hands you need to have some activities planned. Every child benefits from fun that is also educational, and 10 fun projects with magnets fill the bill nicely. This list is divided evenly between “experiments” (1 through 5) and “projects” (6 through 10) so you can keep the attention of your budding scientists as well as your future artists.

There are plenty of places to get your magnets, and don’t forget the many different kinds available. They come in all sizes and shapes, colored and plain, and even in flexible sheets that can be cut into any shape.

For the following activities, you will need a variety of magnets and other supplies. Instead of making one materials list for you, however, it is suggested that you decide which activities you (and your kids) want to do, then assemble your supplies from the list in each activity description.

Note: The “you” in the following instructions can mean the parent or the child. Frankly, these activities are fun and interesting for all ages!

  1. Make a compass

You will need the following items: – non-metallic bowl filled with water – metal pin – magnet – cork

This experiment will show how to make a compass that points true North.

Magnetize the pin by holding it in your hand and stroking it with the magnet in one direction only, from the base (head) to the point. Lift the magnet off at the point, then begin again at the base. Repeat this at least 25-30 times.

Now push the pin through the piece of cork so that the cork is in the middle of the pin, and put the cork/pin in the (non-metallic) water-filled bowl. The pin should have been made magnetic enough to point North.

You can also try seeing how strong your new pin magnet is by seeing if it will pick up small metal objects, such as paper clips.

  1. Polar attraction/repulsion A

You will need the following items:

– two (2) bar magnets

Magnets, of course, have north and south magnetic sides. Depending upon which ends (or sides) that you force together, they will either attract strongly or not at all. If you put north and south magnetic poles together, they will attract. If you put two similar sides together, north or south, they will either not attract or they will actually repel one another.

With this experiment, you and your children will discover the force of the attraction or the repulsion of the magnet.

Place two opposite ends together and you will notice that they instantly attract to one another. Lesson: north and south poles on the magnet attract one another, at different strengths depending on the magnets and the conditions.
magnetic sweepers
magnet sweeper

Now try to force the two north sides of the magnets together. You will be able to feel as the poles repel one another. You can do the same thing with the south sides and will notice the same effect. You can measure the force by holding the same poles together and slowly releasing your hold on the magnets.

  1. Polar attraction/repulsion B

Using the same bar magnets, place them down on a table. Take one magnet with north side pointing forward and push it close to the other magnet’s north side. The magnet you are not holding will move away from the one you are, and even try to turn itself around.

This shows that the south side is attracting your magnet’s north side. You can determine the magnet strength by seeing how far away you can be and still have these effects.

  1. Polar attraction/repulsion B Again using the same kind of magnets, but three to five of them, experiment with pushing the magnets in a kind of “magnet train.” Line magnets up with south sides facing south and north sides facing north, then push the first magnet and watch the other magnets jump forward.

Keep lining up magnets this way and see how many you can get to work together in your “train.”

  1. The floating magnets

You will need the following items:

– five (5) to eight (8) “donut” magnets (the ones with the holes in the middle) – one (1`) wooden rod that will fit through magnet holes – base for rod (wood or modeling clay)

If you cannot buy or construct a base for the rod, you can stand it up in a wad of modeling clay. It won’t be bearing much weight, so it doesn’t have to be “over prepared.”

push pins

First, determine the magnetic forces of the donut magnets and which side is north or south.

Remember, of course, that polar opposites attract. Now put three or four magnets along the bottom of the wooden rod as it is standing. The positioning of the magnets is important: Place all of the magnets with south at the bottom, so when you stack up the three or four magnets, the north (top) part of the bottom magnet will attract the bottom (south) side that you place on top of it. Thus, at the very top of the pile, you will have a north side.

Place the next magnet with the north end down. It will not attract to the north side below it, so it will “hover” over the other magnets. You can continue the hovering demonstration by placing another magnet, south side down this time, on the rod. This new magnet will also hover, as will any others you position on the rod (remembering to alternate the north/south orientation).

  1. Sheet magnet fun A: Refrigerator magnets

You will need the following items:

– several letter-size sheets of flexible magnetic material, white on one side – family photos or kids’ artwork – glue or paste, scissors

Have the kids decide whether they want to make their refrigerator magnet with a drawing or a photo. It could be great fun for each child to make his or her own photo magnet.

therapeutic bracelets

Cut the drawing or photo out and trim it nicely. Place it on the magnetic sheet and trace the shape with a pencil, then cut the shape out of the magnetic sheet. Glue the drawing or picture to the magnetic material.

  1. Sheet magnet fun B: Word magnets

You will need the following items:

– list of common words for sentence formation (Internet) – computer and printer (alternative: Sharpie pens) – several letter-size sheets of flexible magnetic material, white on one side – glue or paste, scissors

On the Internet you will find various sources for lists of commonly used words. You need a selection of nouns, verbs, articles and other kinds of words for sentence formation, but include a few family favorites, names, nicknames, etc.

Print out the list on your computer printer, with each word in a 1/2-inch by 2-inch area. Alternatively, if you do not have a printer you can use Sharpie pens to write the words on 1/2-inch by 2-inch strips of the magnetic sheet.

Cut and paste the words onto appropriately sized strips of the sheet material. Place the magnetic words on the refrigerator or stove front. Leave surprise messages for one another, make up silly sayings or have fun just jumbling them up!

  2. magnet toys

You will need the following items:

– several letter-size sheets of flexible magnetic material, white on one side – kids’ artwork and old magazines (for pictures, words) – glue or paste, scissors

Trace a standard business card on the sheets, or draw a 2-inch by 3.5-inch rectangle. Have your kids find pictures that apply to their personalities – tigers for the rough and tumble, princesses for the dainty little ladies, or vice versa! They can write their names, and make themselves the president of any company they’d like to invent. The finished cards can go on the fridge, inside their school lockers or anywhere else a magnet will stay put.

  1. Colored magnet tic-tac-toe

You will need the following items: – bag of colored magnets (same size, different colors) – a 5-inch square of magnetic sheet, white on one side – ruler and Sharpie pen

Draw a tic-tac-toe playing square on the magnetic sheet. This will go on the fridge, the front of the stove or some other centrally located place. Keep a bag of similarly-sized magnets of different colors near the play square and, picking one color for yourself and another for your opponent, make a tic-tac-toe move each time you pass by that area. Check through the day and watch for your opponent’s move. This is a great way to stretch a game of tic-tac-toe out for a day, sometimes, while giving you the opportunity to grab a snack out of the fridge, too.

You will need the following items:

– bar magnet, at least 1/2-inch wide, three (3) to four (4) inches long – paper, colored pens and pencils, scissors, glue

Trace the shape of the bar magnet onto a piece of paper. This will show you how much room you have to write your name and draw a design. You can write your name simply or color your letters differently, even adding designs and other shapes. Cut the piece of paper out and glue it to the side of the bar magnet. Now you have a way to put your “to do list” or your “memo to Mom” on the fridge door, stove front or any other magnetic spot.
