Observations of 12CO at high redshift indicate rapid metal enrichment in the nuclear regions of at least some galaxies in the early universe. However, the enrichment may be limited to nuclei that are synthesized by short-lived massive stars, excluding classical “secondary” nuclei like 13C. Testing this idea, we used the IRAM Interferometer to tentatively detect the 13CO J = 3 → 2 line at a leve...

chondroma is a benign tumor which mostly occurs in extremities but also sometimes in brain. most intracranial chondromas arise from skull base, but chondroma of falx origin is a rare circumstance. indeed, the intracranial chondromas rise from falx is mostly in relation with syndromic disorders such as mafucci's syndrome or ollier's syndrome. here, we reported a rare case of falxian intracranial...

forty-nine preserved specimens (31 male and 18 female) of trachylepis aurata transcaucsasica were examined with respect to metric and meristic features and dry skull anatomy to assess sexual dimorphism. thirty-one morphological characters and 36 anatomical characters in dry skulls were examined. subdigital lamellae under the forth toe, neck length, neck length/snout vent length, and six skull c...

The case reports of four patients with breakage of the intramedullary nail of the femur are presented. In all four patients the nail broke after consolidation of the fracture of the femoral shaft. All the nails broke at the same place: the junction between the round cross-section and the cloverleaf cross-section.

We report the detection of HCO(J=1→0) emission towards the Cloverleaf quasar (z = 2.56) through observations with the Very Large Array. This is the first detection of ionized molecular gas emission at high redshift (z > 2). HCO emission is a star formation indicator similar to HCN, tracing dense molecular hydrogen gas (n(H2) ≃ 10 5 cm) within star–forming molecular clouds. We derive a lensing–c...

Fixation of comminuted or osteoporotic fractures in the proximal humerus is a challenge for orthopedic surgeons. In the past two decades, locking plates have been used for proximal humeral fracture fixation. However, complications such as loss of reduction have been reported, and the implants are not always available in some regions. Therefore, we describe an alternative procedure involving fix...
