Galena-sphalerite-quartz (lead-zinc ore) from Mexico. (4.2 cm across at its widest)
Silvery-gray = galena (PbS)
Mottled brownish-gray = sphalerite (ZnS)
Whitish-gray = quartz (SiO2)
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5200 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The sulfide minerals contain one or more sulfide anions (S-2). The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals. Many sulfides are economically significant, as they occur commonly in ores. The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc. Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size. These minerals will not form in the presence of free oxygen. Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.
Galena is a lead sulfide mineral (PbS). It has a metallic luster, silvery-gray color, cubic crystals, cubic cleavage, is moderately soft, and has a very high specific gravity (it's very heavy for its size).
Galena is the most important lead ore mineral. It's principally found in hydrothermal vein systems and in Mississippi Valley-type deposits. Silver (Ag) can fall into the lead position as an impurity, sometimes in relatively high proportions. This results in argentiferous galena, (Pb,Ag)S.
Historically, lead from galena has been used as a gasoline additive, a paint ingredient, and for making bullets. Lead is also used to make various metal products, batteries, and radiation shielding.
Locality: Meche Mine (a.k.a. Moche Mine), Zacatecas, central Mexico

Mr and Mrs Nyirienda have been chosen to act as lead farmers in their community.
FYF's innovative 'lead farmer' approach draws on the skills of the farmers themselves and empowers them to ‘show the way to success’ to their fellow farmers.
Each lead farmer is trained to demonstrate sustainable farming techniques to 100 fellow farmers.
By employing these techniques farmers are already seeing massively improved crop yields, meaning that they can feed their families throughout the year.

Kajal = Kohl is an ancient eye cosmetic. It was made by grinding galena (lead sulfide) and other ingredients. It is widely used in South Asia, the Middle East, North Africa, the Horn of Africa, and parts of West Africa to darken the eyelids and as mascara for the eyelashes. It is used mostly by women, but also some men and children.
Kohl is known by various names in South Asian languages, like sirma or surma in Punjabi,kajal in Hindi and Urdu, kanmashi in Malayalam, kaadige in Kannada, kaatuka in Telugu and kan mai in Tamil. In India, it is used by women as a type of eyeliner that is put around the edge of the eyes. Even now in southern rural India, especially in Karnataka, women of the household prepare the kajal. This home-made kajal is used even for infants. Local tradition considers it to be a very good coolant for the eyes and believes that it "protects the eyesight and vision from the sun".
In Punjabi culture, sirma or surma is a traditional ceremonial dye, which predominantly men of the Punjab wear around their eyes on special social or religious occasions. It is usually applied by the wife of brother or the mother of the male.
Some women also add a dot of kajal on the left side of the foreheads or on the waterline of the eye on women and children to protect them from 'buri nazar'. 'Buri nazar' literally means 'bad glance' and is comparable to the 'evil eye', although it can be interpreted as ill-wishes of people or even lustful eyes, in the sense of men ogling women.

It’s a sugar coated version of XP that conflicts with my video editing programs. Microsoft has made it harder to move files with no “move” feature. They have taken away the windows picture viewer and gif images don’t work without extra software.
The switch to box wouldn't let me switch mto moizilla on a download for an upgrade to snagit.

Installing windows 7 signature edition on 32 bit and 64 bit. I had to wipe the 32 bit because 7 wouldn’t recognize windows 7 RC. Install of fresh 7 took About 40 minutes. From Vista 64 bit 7 copied and saved programs and data of @ 400gb on my lt and @ 80 programs in @ five hours! That was nice!

Wipe 7 32 bit because of ati problem. Starting re install
To ready desktop:
10/10/2009 10:08:59 PM
A wipe did not fix the ati glitch on a reinstall.
Windows 7 changed back to windows 7 basic color scheme and the tuner came back on. I had just plugged the tuner into Laptop 2 64bit vista and ati 650 worked. Then all of a sudden the tuner started working again on my 7 lt. Weird coincidence.
10/14/2009 4:21:42 AM
Uninistalling Roxio and using a windows basic or Aero theme in Display settings then re-installing the 650 program over the existing install made the 650 work for me again. I dare not mess with Windows TV tuner!
For those with simple need that don’t need a TV tuner I sugest Windows 7 Ultimate. For those willing to troubleshoot your ATI tuner I also suggest Windows 7 Ultimate!
10/14/2009 11:23:51 PM
A windows 7 update today caused the ati not to work again. It plays but is slow.
10/17/2009 5:16:59 AM
I had to reverrify my activation key on the 32 bit.
I can only network 2 machines that are both on 7.
10/17/2009 10:12:32 PM
A clean uninstall of the 650 then re-install AFTER re-installing roxio fixed it so far.It’s working with roxio now. Roxio’s TV tuner and the ati tuner are working. If you put in ati first before Roxio then Roxio won’t let you install ati.
Hp 7350 photo printer won’t work with hp laptop 64bit and 7 desktop 32bit. No compatible drivers I have found so far have helped.
I can’t figure out how to sort icons in Quick launch with 7.

Lead alloy pendant with opaque red glass inset. Possibly 7th Century AD. Found at Alington Avenue, Fordington, Dorchester. This object is currently held at the Dorset County Museum.
This reminds me of my favorite scene from the Bollywood movie Three Idiots...
"First day of college, you asked me why didn't astronauts use a pencil in space?"
"If a pencil tip breaks, it'd float on zero gravity; get into the eyes, nose, instruments.
You were wrong. You cannot be right all the time."
Well if you guys have watched the movie, you'd see the same ulterior meaning. =)
I’m not sure you’ll remember but you and I spoke about balancing my BADASS powered KAOS kit a couple of weeks ago. You had suggested a bit of weight inside the openings in either the rudder or elevator. I only need a couple of ounces, at the most, and was able to tuck two short pieces of some lead rod (approx 3/16” OD, pure lead so easily bendable) in to the two most inboard pockets in the elevators. It worked perfectly.
Since then, I’ve made excellent progress and am only awaiting the delivery of a Jeti ESC with BEC and telemetry before the maiden flight. With a 6S LiPo tucked as far back as possible, per the instructions to remove a portion of F2 (F3?) to allow it to sit with the back end of the battery just slightly sitting inside the battery compartment, balance is right on. Also, it gives me a bit of room to move the battery slightly forward for a bit of a nose down balance at the CG point that is called out on the plans.
As we spoke a while back, I am 67 and have been flying RC since I was 12. When the KAOS kit first came out, I fell in love with it and always wanted to build one but never got around to it. But I do remember being given the transmitter sticks of one of our friends and realizing what a great pattern ship it was, and now, is once again! Your kit is excellent; proper wood densities and thickness, unparalleled laser cutting and a true joy to build. It is so accurately cut that if a part is not fitting the way the plans show, you know you’ve done something wrong . . . its not the cut of the part! It reminds me of when I built a VANS RV-9A experimental/amateur-built aircraft. If the rivet pilot holes didn’t line up, you know you screwed up!
So, without further ado, here’s my KAOS. I am using the BADASS 10cc equivalent motor called for on the Innovative website. It will be powered by a 6S 5Ah LiPo turning an 11x7e prop. My bit of customization is visible in one of the photos. My cooling air scoop is conical in shape; formed from a toilet paper roll tube and reinforced with some thin surgical gauze and epoxy. I think the shape is more in tune with the rounded forward fuselage ends at the motor compartment. Note too, the black painted canopy (last photo). . . guess the pilot will need to fly IFR as they can’t see outside the canopy?!
Thanks again for re-kitting the KAOS and for you support. As a former small business entrepreneur I understand low margin businesses. I applaud your efforts and I will definitely buy another kit from OSMW!
This lead was in a Kindergarten and has been chewed by the pet rabbit. Staff had covered with tape - however a new lead would have been safer for all! Copper wire visible.

Lead Me Not Into Temptation... [163/365] - Eating healthy, Day 12 is a success, although it was far from easy. This morning the lady from the agency that recruited me for my job came into my office with a box of donuts. Suddenly, my carrots didn't look as yummy as I'd convinced myself that they were. I stared at the donuts... I even put my nose close enough to smell them, but I did NOT eat even one bite. Trust me, it wasn't easy getting through the work day knowing that box of deliciousness was in the office.
After work, it was off to Ryan's house for his graduation party, where I found myself faced with even more challenges. Cupcakes, ice cream cake, chips, soft drinks... oh the madness! With Ryan's encouragement I filled my plate with healthy snacks, and life went on. Only 9 more days of this crazy challenge!
Happy Thank God It's Food Day!!
