The pathway of dehydration and intramolecular cyclization of lisinopril dihydrate in the solid state was investigated using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and a combination of thermal analyzer with Fourier transform infrared microspectroscopy (thermal FT-IR microscopic system). The results indicate that the dehydration from the solid-state lisinopril d...

Top surface imaging (TSI) has had an interesting history. This process showed great promise in the late 1980’s and several attempts were made to introduce it to full-scale manufacturing. Unfortunately, defect density problems limited the process and it fell from favor. TSI emerged again as an important part of the EUV and 193 nm strategies in the early stages of those programs because it offere...

We print here the first English translation of a discussion of Solzhenitsyn’s Gulag, I1 by the distinguished Russian historian and intellectual dissident Roy Medvedev. Elsewhere in this issue, Peter Reddaway analyzes the exchanges of opinion going on among the Russian dissidents. We believe that the issues raised by people like Solzhenitsyn, Sakharov, and Medvedev-including their differences of...

The pentadecapeptide BPC 157 has been shown to have anti-inflammatory and wound healing effects on multiple target tissues and organs. The purpose of the present study was to investigate the effect of BPC 157 on inflammation and bone resorption in experimental periodontitis in rats. First the acute effect of BPC was tested on gingival blood flow by laser doppler flowmetry. Then periodontitis wa...

Esophagocutaneous fistulas are a failure of the NO-system, due to NO-synthase blockage by the NOS-blocker L-NAME consequently counteracted by l-arginine and gastric pentadecapeptide BPC 157 (l-arginine <BPC 157), precipitating a therapeutic benefit. Previously, there was an established BPC 157-NO-system interaction. BPC 157 GEPPPGKPADDAGLV, MW 1419 (LD1 not achieved), is a safe and stable anti-...

XeF( C --* A ) laser radiation has been produced in a fivecomponent gas mixture excited by a coaxial electron beam with an intermediate pulse length ( 175 ns) and pumping rate ( 1 MW/cm'). The laser output energy was 215 mJ from an active volume of 157 cm3 (1.4 J / L ) at a total gas pressure of 8 bar corresponding to an intrinsic

Problem 1: Evaluating Convex Polygons This write-up presents several simple algorithms for determining whether a given set of twodimensional points defines a convex polygon (i.e., a convex hull). In Section 1.1, we introduce the notion of regular polygons and provide examples of both convex and non-convex point sets. Section 1.2 presents an algorithm for ordering a set of points such that a cou...
