[howto] Stain Removal

STAIN REMOVAL

Introduction

• Never use very hot water for washing stained garments as this often sets the stains and makes them very difficult or impossible to remove.
  
• Some stains are more easily removed by washing if they are soaked first in cold water, e.g. mud and blood stains, and the brown stain from shoe inner soles.
  
• The use of chemicals is required for removing certain stains. Carry out this treatment before washing. Remove all traces of the chemical.
  
• To apply a stain removing agent to fabric, place a fold of clean rag underneath the stain so that any surplus moisture is absorbed.
  
• To prevent a ring forming around the stain, work from the outside of the stain, in an uneven circular shape, towards the centre, dabbing it very lightly with a pad of clean rag which has been dipped in the removal agent.

STAIN REMOVAL CHART
BLOOD	Soak in cold salted water (1 teaspoonful to 1 pint) for at least an hour. Wash in warm soapy water.
COCOA/COFFEE/FRUIT JUICE	Sponge with a warm solution of borax and water. Rinse well and wash according to fabric.

EGG: WHITE	Soak in cold water, then treat with lukewarm salt solution (1 teaspoon to 1 pint)
EGG: YOLK	Wash according to fabric and remove the greasy mark with a grease solvent.
GRASS	Dab with surgical methylated spirit over an absorbent pad. Wash according to fabric. TEST RAYON BEFORE TREATMENT.
GREASE	(1) Use a grease solvent, i.e. benzene or carbon tetrachloride. (2) A surface grease may be removed by putting the fabric between blotting paper and pressing with a hot iron.

[howto] Copy Excel Subtotal Data

From MrExcel.com

Use the Goto - Special command to copy just the subtotals to a new area.

You can use the Data - Subtotals command to automatically subtotal a range of data as shown above left. After creating subtotals, Excel will show the outline symbols to the left of your worksheet. By clicking the "2" outline symbol, Excel will display only the subtotal lines. This is really cool, but many people have trouble when they try to copy this information to a new worksheet. It looks like there are just five rows of data, but when you copy and paste elsewhere, you will find that Excel copied the hidden rows as well.

The solution lies in the obscure but powerful GoTo Special functions. Here are the steps:

• Highlight the range you want to copy.
• Click on Edit, then Goto.
• On the right side of the Go To dialog is a button marked "Special". Click "Special" to see the Go To Special dialog box.
• Click the button for "Visible Cells Only" and click OK. This changes the selection from all 14 rows to just the five visible rows.
• Now that you have just the 5 visible rows selected, you can do Edit - Copy (or Ctrl-c), click in a new cell in a blank range of spreadsheet, and Edit - Paste (Ctrl-V) to paste just the subtotals.

[howto] Excel 2 Latex

excel2Latex

It's difficult to create tables in LaTeX, especially if some columns are
calculated. Excel2LaTeX allows you to transform the current selection from
Excel to Latex. Most of the formating will be kept (bold, italic, border
lines, multicolumn cells, etc.). The LaTeX code can be copied to the
clipboard or saved as a LaTeX file, which then can be included in an
existing LaTeX document using the \input command.

JabRef is an open source bibliography reference manager. The native file format used by JabRef is BibTeX, the standard LaTeX bibliography format. JabRef runs on the Java VM (version 1.5 or newer), and should work equally well on Windows, Linux and Mac OS X.

[howto] Excel: How to group rows

I had a big problem to calculate on the groups of rows in excel file.
For long time, I did do it manually. Many times, I wrote my own specific program to take care of this problem.

That was a stupid way.

Excel2003, Ecel20007 can group the rows for you.
