We present results of an ongoing program at the ESO VLT for spectroscopy of BL Lac objects lacking a firm redshift estimate and here we report on 15 objects. For 11 sources we confirm the BL Lac classification, and we determine new redshifts for 3 objects, 1 with weak emission lines (PKS 1057−79, z = 0.569) and 2 with absorptions from the host galaxy (RBS 1752, z = 0.449; RBS 1915, z = 0.243); ...

OBJECTIVE The current study aimed to investigate the association of wrist circumference with major cardio metabolic risk factors. METHODS This study was conducted in 2005-2007 among 3000 first-degree relatives of diabetic patients in Isfahan, Iran. RESULTS Overall, 1709 (386 males and 1323 females) participants were enrolled in this study. The association of wrist circumference with cardio-...

User performance with a tabletop display was tested using touch-based and mouse-based interaction in a traditional pointing task. Dependent variables were throughput, error rate, and movement time. In a study with 12 participants, touch had a higher throughput with average of 5.53 bps compared to 3.83 bps for the mouse. Touch also had a lower movement time on average, with block means ranging f...

A series of 1,3,5-triazine derivatives that contain 4-amino-2-trifluoromethyl-benzonitrile, 8-hydroxyquinoline, and different piperazines as substituents at the carbon atoms of the triazine ring have been synthesized by a simple and efficient synthetic protocol. The chemical structures of the compounds were elucidated with the aid of IR, 1H NMR and 13C NMR spectroscopy, and elemental analysis. ...

Bed elevation, feature adjustments, and spawning use were monitored at three Chinook salmon (Oncorhynchus tschawytscha) spawning habitat rehabilitation sites to measure project longevity in a regulated river. Sites enhanced with 649–1323 m of gravel lost from 3–20% of remaining gravel volume annually during controlled flows of 8–70 m/s and 2.6–4.6% of placed material during a short-duration (19...

ISSN: 2278 – 1323 All Rights Reserved © 2014 IJARCET 3504  Abstract— True random bit generator requires a naturally occurring source of randomness. Designing a hardware device or software program to exploit this randomness and produce a bit sequence that is free of biases and correlation is difficult task. For most cryptographic applications, the generator must not be subject to observation or...
