Introduction Most living things appear rather symmetrical: the external human form, for example, has a plane of mirror symmetry to good approximation. Snails, flounders, narwhals, crossbills, fiddler crabs and twining vines are members of the short but fascinating list of living things known instead to defy mirror symmetry by exhibiting exterior chirality. The study of this symmetry breaking li...

Over the past 25 years the rate of twin and higher - order multifetal birth have increased between 1980 and 2005. The twining rate rose from 18.9 to 32.1 per 1000 live birth. Multifetal gestations are at high risk of fetaland complication such as; growth restricted fetal death, LBW and cerebral palasy. Maternal complication are that also increased such as: preeclampsia, diabetes, maternal death...

In the present study a deterministic bio-economic model was used to estimate economic values for reproduction traits (conception rate, twining rate and litter size), production traits (body weight of kid sold at 6.5 months, annual cashmere weight, body weight of doe and annual milk yield) and longevity (survival of doe, survival of kid until weaning and survival of kid until sale age at 6.5 mon...

The present study was conducted to evaluate the role of age in effectiveness intravaginal progestin-impregnated sponges (IPIS) along with equine chorionic gonadotropin (eCG) on multiple birth rates Awassi ewes. One hundred mature ewes (live weight 35–40 kg and 2–5 years) were allocated three groups according their ages (n = 29, 2-3 years;n 34, 3-4 years; n 37, 4-5 years). All impregnated IPIS, ...

Picard groups of tensor categories play an important role in rational conformal field theory. The Picard group of the representation category C of a rational vertex algebra can be used to construct examples of (symmetric special) Frobenius algebras in C. Such an algebra A encodes all data needed to ensure the existence of correlators of a local conformal field theory. The Picard group of the ca...

Tensile test on smooth and circumferentially notched specimens, systematic observation of fracture surfaces and large deformation finite element analysis were conducted to understand the deformation and failure behavior of a magnesium alloy (AM60). The plastic deformation is considered to be dominated by twining mediated slip. The tensile properties were not sensitive to the strain rates applie...

As David and Brierley (1968) pointed out, each political society in the world has its own law. In fact, it frequently happens that several laws coexist within the same state. Moreover, law is not static; it is in a state of flux, of evolution. The development of the law is shaped by logic, history, custom and utility, as well as the accepted standards of right conduct (Cardozo, 1921). It is the...
