BACKGROUND Exposures to dog and cat allergens are believed to play important roles in the etiology of asthma; however, the levels of these allergens have never been assessed in a representative sample of US homes. OBJECTIVE The objective of this study was to estimate and characterize exposures to Can f 1 (dog allergen) and Fel d 1 (cat allergen) in US homes. METHODS Data were obtained from ...

acid sequences showed considerable similarity te wheat and barley or-amylaseltrypsin inhibitor$ which haye recently been identified as major altergens ass(K iated with baker's asthma. An antisense RNA strategy was applied to repress the allergen gene expression in maturing rice seeds. Immunobloning and ELISA analyses of the seeds using a monoc]onal antibody to a lekDa allergen showed that aller...

Leiomyoma of the orbit, a benign tumour of sniooth muscle, is exceedingly rare (Reese, I963; Offret and Haye, I97I). Furthermore, its diagnosis is suspect when one fails to demonstrate non-striated cytoplasmic filaments convincingly. The present case is reported for three reasons: (i) It is the only orbital leiomyoma in the files of the Eye Institute; (2) It has a well-documented clinical cours...

The equations providing to describe generation process in FEL with varied parameters of diffraction grating (photonic crystal) are obtained. It is shown that applying diffraction gratings (photonic crystal) with the variable period one can significantly increase radiation output. It is mentioned that diffraction gratings (photonic crystal) can be used for creation of the dynamical wiggler with ...

The feasibility of a CLIC-LHC based FEL-nucleus collider is investigated. It is shown that the proposed scheme satisfies all requirements of an ideal photon source for the Nuclear Resonance Fluorescence method. The tunability, monochromaticity and high polarization of the FEL beam together with high statistics and huge energy of LHC nucleus beams will give an unique opportunity to determine dif...

One of the most important subjects of the high-gain FEL engineering is the calculation of the gain length, and fitting formulas are frequently used for this purpose. Here we refer to Ming Xie fitting formulas [1] and fitting formulas for optimized FEL written down in an explicit form in terms of the electron beam and undulator parameters [2]. In this paper we perform generalization of these fit...

A double-achromatic, double-focusing magnet system of very small size is described which will be used in the injection line for an undulator in a FEL experiment . Because of the double focusing no quadrupoles are needed between the dipole, which couples the electrons in the FEL cavity, and the undulator. An example will be worked out for an electron bunch of 25 MeV, 100 Awhich is focused on a s...
