در این مقاله پس از معرفی مختصر روش جدا کردن سازه ها برای مبارزه با نیروی مخرب زلزله ،روشی ساده برای تحلیل دینامیکی چنین سازه هایی بیان گردیده است. اساس این روش بر آن است که سازه مورد نظر با نوسازگری دارای یک درجه آزادی جایگزین شود تا آنالیز طیفی آن براحتی امکان پذیر گردد. اگرچه این روش بر پایه یکی کردن طیف دو سیستم واقعی و معادل بسط داده شده است، اما نشان داده می شود که رفتار دو دستگاه از نظر ت...

A high water content lens (Scanlens 75, +14.5 dioptres) and a low water content lens (Bausch and Lomb Soflens H3, +14.5 dioptres) were compared with respect to corneal thickness response after 6 hours of wear in a provocative test on 12 aphakic eyes. The mean increase in central corneal thickness was 3.3% for Scanlens and 6.4% for Soflens. This difference is statistically highly significant (p ...

Law360, New York (November 19, 2013, 12:36 PM ET) -As we've seen this year in disputes involving companies such as Victoria's Secret, Accenture and Bausch & Lomb, a catchy slogan can do more than just get consumers to notice and buy a product or service. An effective slogan also can draw attention from competitors. Giving in to the urge to "just do it" when selecting a slogan could be a mistake...

We present the results of a systematic search in 8.5 years of Rossi X-ray Timing Explorer All-Sky Monitor data for evidence of periodicities. The search was conducted by application of the Lomb-Scargle periodogram to the light curves of each of 458 actually or potentially detected sources in each of four energy bands (1.5–3 keV, 3-5 keV, 5-12 keV, and 1.5–12 keV). A whitening technique was appl...

The final data of the Gallex and GNO radiochemical experiments have been searched for possible time modulations of the solar neutrino capture rate using the LombScargle periodogram and the maximum likelihood methods. Both analyses, performed using the raw data, do not support the presence of a time variability with characteristic periods resembling those of rotation of the solar magnetic fields...

CircaDB (http://circadb.org) is a new database of circadian transcriptional profiles from time course expression experiments from mice and humans. Each transcript's expression was evaluated by three separate algorithms, JTK_Cycle, Lomb Scargle and DeLichtenberg. Users can query the gene annotations using simple and powerful full text search terms, restrict results to specific data sets and prov...

MARCH 2007 I CATARACT & REFRACTIVE SURGERY TODAY I 37 W ith its new Stellaris Vision Enhancement System (FDA approved, commercial launch in US planned for April 2007) (Figure 1), Bausch & Lomb (Rochester, NY) has designed an integrated phaco platform with advanced technology and precise instrumentation that will facilitate surgeons’ transition to the newer microincisional phaco techniques. The ...

Most patients with glaucoma exhibit elevated intraocular pressure (IOP). A cost effective device that allows the patient to measure IOP at regular intervals may reduce vision loss. This research tested the Bausch & Lomb Proview self tonometer against a calibrated force meter. It further compared the Proview tonometer with results from the clinical gold standard, the Goldmann tonometer. Results ...

Onboard satellite clocks are the basis of Global Navigation Satellite Systems (GNSS) operation, and their revolution periods at level 2 per day (about 12 h) in case Medium Earth Orbit (MEO) satellites. In this work, authors analysed entire BeiDou System (BDS) space segment (BDS-2 BDS-3) terms occurrence periodic, repetitive signals clock products, checked if they coincide with orbital or multip...
