The optical transmittance of the commonly used Cerenkov counter gases, Freon 12, Freon 13; C02, SF8, and N2, was measured in the range from 1875 A to 8000 A, and normalized for a 100 cm X 1 atm path. Calculations of efficiency for Cerenkov counters, particularly threshold type, require a knowledge of the optical transmittance of the counter filling for the Cerenkov light. For many of the gases ...

We report the case of a patient presenting with a 3-cm diameter ulcerated nodular basal cell carcinoma in the frontal left region, reaching the medial half of the eyebrow. The lesion was excised, and the reconstruction was realized with advancement fl aps in H; the left region included the rest of the eyebrow, and it was larger than the contralateral region. Thus, the harmony and symmetry of th...

We investigated the electronic properties of N(5)-ethyl flavinium perchlorate (Et-Fl(+)) and compared them to those of its parent compound, 3-methyllumiflavin (Fl). Absorption and fluorescence spectra of Fl and Et-Fl(+) exhibit similar spectral features, but the absorption energy of Et-Fl(+) is substantially lower than that of Fl. We calculated the absorption signatures of Fl and Et-Fl(+) using...

Materials and methods: Th e study group comprised 33 individuals who underwent TET with suspicion of myocardial ischemia, but no evidence of ischemia and with hypertensive response to TET, and the control group comprised 29 ageand gender-matched subjects. All participants underwent echocardiographic examination, brachial artery ultrasonography, and aortic ultrasonography for the assessment of l...

Pearls and Pitfalls in Head and Neck Surgery Introduction The EBSLN is the main motor supply to the CTM. The contraction of this muscle stretches the vocal fold, especially during the production of high frequency sounds [1] . Therefore, EBSLN paralysis leads to an important impairment of voice performance, mainly among women and voice professionals. This nerve crosses the superior thyroid vesse...

A, Contrast-enhanced axial enhanced CT scan through the thoracic inlet demonstrates a 2-cm, homogenously low-attenuation nodule in the right lobe of the thyroid accessible to ultrasound fi ne-needle aspiration (arrow). B, High-frequency transverse ultrasound image of the neck demonstrates a predominantly hypoechoic fl uid-containing lesion in the righ...

1. Complex multiplication. We say an abelian variety A of dimension g over a field K admits sufficiently many Complex Multiplications (smCM) if D = End(A) contains a commutative semi-simple algebra Λ ⊂ D of rank dimQ(Λ) = [Λ : Q] = 2g. In this case we say A is a CM abelian variety. A point z ∈ Ag(k) is called a CM point if z is the moduli point of a polarized abelian variety z = [(A,μ)] such th...

A patient with a normal blood hemoglobin was found to be heterozygous for a new level, but with evidence of brisk hemolfl-chain mutation and fl-thalassemia. All ysis, was found to have an unstable of the hemoglobin in his red cells was of hemoglobin with a left-shifted oxygen the abnormal type, designated hemodissociation curve. Two sisters of the paglobin Duarte, and was shown to contain tient...
