This landmark study is the first comprehensive exploration of the
`Proportioned Script', an Arabic writing system attributed to the
Abbasid wazir (minister) Ibn Muqla and the master scribe Ibn
al-Bawwab that has dominated the art of Arabic and Islamic
penmanship from the 10th century to the present day. Volume One,
`Sources and Principles of the Geometry of Letters', traces the
origin of the Proportioned Script to the cross-cultural encounter
between Greek learning and the scientific, artistic and
philosophical pursuits of classical Islam. On the basis of
instructions in surviving sources it identifies a grid module that
serves as a common foundation for the design of all the Arabic
letter shapes. In Volume Two, `From Geometric Pattern to Living
Form', the authors construct each of the letter shapes on the grid
module and compare their findings to samples traced by two
classical master scribes. They conclude by examining the religious,
aesthetic and cosmological significance of the Proportioned Script
in the wider context of the Islamic cultural heritage. Drs Moustafa
and Sperl have succeeded in unearthing the very foundations of
Arabic penmanship, with implications for the arts of Islam as a
whole.
The Psychology and Neuroscience of Impulsivity is the first book to
provide a comprehensive overview of impulsivity and related
psychological and neural substrates. The book is divided into four
sections, the first section, will provide the readers with a
general overview of impulsivity, neural and cognitive substrates of
impulsive behaviors, and the relationship between impulsivity and
risk-taking behaviors. The second section discusses the links
between impulsivity and erroneous behaviors, such as anger and
aggressive behaviors and interpersonal violence. The third section
reviews how impulsive behaviors are key features of several
clinical disorders, such as pathological gambling, drug abuse, and
antisocial personality disorder. The last section, presents
possible treatment options for impulsivity, including a number case
studies.
The main objective of reproductive biotechnology for farm animals
is increasing reproductive efficiency and rates of animal genetic
improvement. Arresting of development for oocytes development
stages is one of the important problem facing researchers and
reduce the rate of maturation and fertilization in vivo and in
vitro. Many researchers are moving towards adding different
supplementations in medium to raise maturation and fertilization
rate in vitro. Since ten years ago, many researchers investigated
the role of Leptin in reproduction and fertility. Leptin is a
cytokine hormone, 167 amino acids and 16 K-Da. It is secreted
primarily by adipose tissues. Leptin increases the proportion of
oocytes that is developed to blastocysts. Adding Leptin to IVM
medium by different levels enhances the maturation rate of in vitro
rabbit oocytes. In this work, author was trying to investigate the
effect of Leptin supplementation at different levels in IVM medium
on rabbit oocyte maturation.
