AS-3-Ketosteroid isomerase of Pseudomonas testosteroni is a homogeneous and crystalline enzyme that promotes the irreversible conversion of A5-3-ketosteroids to A4-3-ketosteroids (1, 2). This enzyme is one of the most active catalytic proteins known, since each mole (molecular weight 40,800) converts 16.7 x lo6 moles of A5-androstene-3, 17-dione (I) to A4-androstene-3, 17dione (II) per minute a...

This work investigated the ironwood used to construct a gambang, which is traditional musical instrument. A gambang constructed from wooden bar with similar thickness and width but different length. The sound established frequencies were compared equal tempered scale. peak differed intended pitch partials not always harmonic. only classified 4 octaves. audio classification of was based on signa...

A method of supervaluation for Kripke's theory of truth is presented. It di ers from Kripke's own method in that it employs trees; results in a compositional semantics; assigns the intuitively correct truth values to the sentences of a particularly tricky example of Gupta's; and it is argued is acceptable as an explication of the correspondence theory of truth. In his (1982) Gupta presents the ...

Let n > 0 be an integer and X be a class of groups. We say that a group G satisfies the condition (X , n) whenever in every subset with n + 1 elements of G there exist distinct elements x, y such that 〈x, y〉 is in X . Let N and A be the classes of nilpotent groups and abelian groups, respectively. Here we prove that: (1) If G is a finite semi-simple group satisfying the condition (N , n), then ...

Komninos, Honary and Darnell recently proposed stream cipher Alpha1. Alpha1 is based on A5/1 and is claimed to be much safer than A5/1. However Alpha1 is insecure: a 29-bit feedback shift register could be recovered with about 3000 known plaintext bits with O(2) operations. The rest of the message could be recovered in the broadcast application in which the same message is encrypted with differ...

Penicillium sp. FO-125, a soil isolate, was found to produce a new antifungal antibiotic complex named atpenin. Three components A4, A5 and B were isolated from the fermentation broth of the producing strain by solvent extraction, silica gel column chromatography and HPLC. The molecular formula of atpenins A4, A5 and B were determined to be C15H22NO5Cl, C15H21NO5Cl2 and C15H23NO5, respectively,...

This issue of Wireless Security Perspectives focuses on GSM and the December 1999 article titled Real Time Cryptanalysis of the Alleged A5/1 on a PC (preliminary draft) by Alex Biryukov and Adi Shamir. The authors describe an attack on the GSM A5/1 traffic encryption algorithm and claim that by analyzing the output of the algorithm, one can recover the cryptographic key in less than a second us...

The HL-A antigens were determined retrospectively in a group of 14 surgically cured bronchogenic carcinoma patients and prospectively in another group of 100 untreated patients. In the retrospective group, the frequencies of antigens W-19 and HL-A5 were significantly increased when compared with the noncancer control and the prospective lung cancer populations. In the latter group, 60% of the p...
