The properties of powerful radio sources at 90 GHz
We have observed a small sample of powerful double radio sources (radio galaxies and quasars) at frequencies around 90 GHz with the BIMA millimetre array, with the intention of constraining the resolved high-frequency spectra of radio galaxies. When combined with other sources we have previously observed and with data from the BIMA archive, these observations allow us for the first time to make...
متن کاملEccrine sweat gland carcinoma.
The differential diagnosis among the most frequent skin tumors, base-cell carcinoma and squamous-cell carcinoma, and the rare types, the sweat gland carcinomas, is fundamental for the early diagnosis and prognosis of a patient. These are classified as eccrine and apocrine, and the eccrine is the most common type. The eccrine sweat glands are most abundant in the palms of the hands and the feet ...
متن کاملA 90 Ghz Photoinjector
Photocathode rf guns depend on mode locked laser systems to produce an electron beam at a given phase of the rf. In general, the laser pulse is less than σz = 10° of rf phase in length and the required stability is on the order of ∆φ = 1°. At 90 GHz (W-band), these requirements correspond to σz = 333 fsec and ∆φ = 33 fsec. Laser system with pulse lengths in the fsec regime are commercially avai...
متن کاملSweat gland adenocarcinoma of the scalp: A case report
Sweat gland adenocarcinoma is a relatively uncommon malignancy. Clinical features are painless red or violet papules and nodules that can occasionally become ulcerated. The biological behavior is aggressive and metastatic sweat gland carcinoma spreads through the lymphatic. The treatment of choice is wide surgical excision with regional lymph node dissection. The portrayed ase was a 60-year-old...
متن کاملSweat induction from an isolated eccrine sweat gland.
SAW, KENZO. Sweat induction from an isolated eccrine sweat gland. Am. J. Physiol. 225(5) : 1147-l 152. 1973.-A method has been developed for in vitro induction of sweating from an isolated monkey-palm eccrine sweat gland. The validity of the new methodology is shown in the following results. MecholyLinduced sweating was completely inhibited by atropine and by cooling the incubation medium to 4 ...
