Congenital cervico-thoracic kyphosis has been encountered in a girl with Pierre Robin sequence. The constellation of the spine malformation complex such as incomplete development of the vertebral bodies associated with defective ossification of the cervico-thoracic pedicles causing effectively the development of complete spinal cord injury at the kyphotic level of C7/T1 were present. Congenital...

let r be a commutative ring with non-zero identity and m be a unital r-module. then the concept of quasi-secondary submodules of m is introduced and some results concerning this class of submodules is obtained

foreign body aspiration of airways is very dangerous and sometimes fatal. early diagnosis and rapid management is vital. the goal of this study was to determine the clinical characteristics, radiologic findings and the results of bronchoscopic treatment of children due to foreign body aspiration of airways. medical records of 101 bronchoscopic proven foreign body inhalators were reviewed in gho...

ingestion of foreign bodies is common and conservative treatment can eliminated most particlesfrom the gastrointestinal tractunless peritoneal signs appear. a 22-year-old man presented to emergency department who had ingested glass particles of a crushed beverage bottle. he complained of epigastric and periumbilical pain. physical examination did not revealany peritoneal signs. abdominal x-ray ...

Synthetic dyes are complex aromatic compounds used in many industries like paper, printing, textile, food and cosmetics [1]. The major synthetic dyes include azo, triphenylmethane, anthraquinone and metal dyes. They are reported to be carcinogenic and thus their safe release into the environment poses a threat to public health. About 10-15% of the substrate unbound dyes from the industries are ...

We give a description of an affine mapping T involving contact pairs of two general convex bodies K and L, when T (K) is in a position of maximal volume in L. This extends the classical John’s theorem of 1948, and is applied to the solution of a problem of Grünbaum; namely, any two convex bodies K and L in Rn have non-degenerate affine images K ′ and L′ such that K ′ ⊂ L′ ⊂ −nK ′. As a corollar...

In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated ...

We study the motion of self deforming bodies with non zero angular momentum when the changing shape is known as a function of time. The conserved angular momentum with respect to the center of mass, when seen from a rotating frame, describes a curve on a sphere as it happens for the rigid body motion, though obeying a more complicated non-autonomous equation. We observe that if, after time ∆T ,...

Neandertal femora are distinct from contemporaneous near-modern human femora. Traditionally, these contrasts in femoral shape have been explained as the result of the elevated activity levels and limited cultural abilities of Neandertals. More recently, however, researchers have realized that many of these femoral differences may be explained by the cold-adapted bodies of Neandertals vs. the wa...

In this paper we present new versions of the classical Brunn-Minkowski inequality for different classes of measures and sets. We show that the inequality μ(λA+ (1− λ)B) ≥ λμ(A) + (1− λ)μ(B) holds true for an unconditional product measure μ with decreasing density and a pair of unconditional convex bodies A,B ⊂ R. We also show that the above inequality is true for any unconditional logconcave me...
