La Muqaddima Ibn Khaldun is translated in English by Abraham L. Udovitch. (No. 3: [3] Life).
In my opinion he is one of the most important Arab historians.
Its interesting to mention that when you search for "Muqaddimah" on Google Books you find a lot of books about other scientists (scientists, scientists, etc.) but nothing about the Historian Ibn Khaldun. (Although this might be an argument of low visibility of a scientific approach in Arabic language.)
In recent years, as a flat display apparatus having low power consumption and low weight, development of a liquid crystal display apparatus has been advancing, and demand for the liquid crystal display apparatus has been growing. The liquid crystal display apparatus includes a liquid crystal display panel in which a liquid crystal is sandwiched between a pair of substrates, an illuminating apparatus that irradiates light from the outside onto the liquid crystal display panel, and a backlight that is disposed on the back of the liquid crystal display panel and that irradiates light onto the liquid crystal display panel from the back side. The backlight includes an illuminating unit that irradiates light on the liquid crystal display panel. In the illuminating unit, a lamp (a cold cathode fluorescent lamp (CCFL), for example) is disposed at the back side of the liquid crystal display panel, and the light irradiated from the lamp is radiated onto the liquid crystal display panel.
In such a backlight, generally, a tapered optical sheet that is tapered in thickness in the direction of flow of light is disposed at the back side of the liquid crystal display panel. In the tapered optical sheet, a plurality of prismatic portions that change in width according to the thickness direction are provided on the surface on the back side of the liquid crystal display panel, thereby changing the direction of the light irradiated from the liquid crystal display panel and efficiently emitting the light in the direction of a viewer, and further, the tapered optical sheet is formed of a light transmissive resin in which a light scattering agent is mixed.
Further, when the light scattered by the light scattering agent is used, the following advantage can be obtained. That is, light of the light irradiated from the liquid crystal display panel is scattered in the tapered optical sheet, and the scattered light can be visually recognized as a light of the backlight. Further, when the light scattering agent that does not absorb 01e38acffe

A breast reduction can be a long and difficult process. In most cases, the outcome is gratifying. Results are not always satisfactory, however. Factors contributing to unsatisfactory results are listed, and corrective measures are suggested. The overall success of breast reduction is dependent on the surgeon's experience, the total number of cases, and the skills and patience of the surgeon. It is important to have a clear understanding of the exact details of the planned operation before the operation is begun.Q:
What is the underlying reason for StringBuffer being evaluated first and then String?
The Javadoc for StringBuffer says
The constructors for StringBuffer and String allocate the internal buffer; this is done lazily, so that repeated construction need not waste memory.
It then says that this isn't actually what happens:
public StringBuffer() {
super();
}
When we call the constructor, the underlying buffer is already there, so we just copy the data over. But we are still doing an allocation. What is it actually doing here?
To make it even more confusing, String does the same thing. The constructors for both of these classes do something like this
public String(String s) {
int n = s.length();
if (n > 0)
char ch[] = new char[n];
System.arraycopy(s.toCharArray(), 0, ch, 0, n);
super(ch);
}
I was looking at the source code, and the code for String.java is in String.h. This is the comment by the developers:
This method is common to String and StringBuilder. It is used by the compiler for StringBuffer.
So StringBuffer does a copy of the underlying buffer, and the source code for String.java and String.h both say that this constructor is for "String", so why is StringBuffer different?
A:
The Javadoc was edited recently to include the actual bytecode generated for the constructor. It appears that StringBuffer invokes String.newString(CharSequence), which does
