Derivation of Test Cases for LAP-B from a LOTOS Specification

this paper, we show how this method has been applied to obtain test cases for LAP-B that are comparable, and in fact occasionally better, than those obtained by [KLPU][Kan]. Since TTCN is a common language for the spec- ification of test trees, the test cases obtained are written in TTCN (we should observe, however, that LOTOS itself appears to be adequate for the specification of test trees [Steen]). This technique appears to be valuable for conformance testing, at least until such time as the more formal approaches being developed by other authors become available (see Section 7). It makes it possible to extract test cases directly from (possibly standardized) formal descriptions, eliminating or reducing the importance of the interpretation of the informally specified standard. The formal specification is more complete and precise than the state tables and, unlike the latter, allows full formal treatment of the data part. For example, we shall show that automatic or semiautomatic generation of frame values appear to be possible by using the information contained in selection predicates

C-Reactive Protein: Potential Significance of Quantitation in Patients with Chronic Diseases

Serum C-reactive protein (CRP) levels in 351 patients with certain chronic diseases were assayed by a micro-double immunodiffusion technique developed and used in this hospital. Elevation of CRP values and severity of disease were evident in the following clinical entities: 31 of 54 patients (57%) with liver cirrhosis; 122 of 204 (60%) hepatitis patients; 34 of 52 (65%) patients with gastro-intestinal surgery; 8 of 21 (38%) uremic patients; and all of 20 patients with renal transplantation. There was good correlation between markedly elevated serum CRP values and degree of inflammation and/or physiologic stress during clinical course and recovery

Efficacy of Betaprone with Ultraviolet Irradiation on Hepatitis B Antigen in Human Plasma Pools (A Retrospective Study)

In a retrospective study, hepatitis B antigen (HB Ag) was found in 14 lots of human plasma pools (16-20 liters each) that had been treated by the combined Betaprone (BPL) with ultraviolet (UV) irradiation procedure. No evidence of clinical hepatitis was found during a six-month follow-up after 185.2 liters of HB Ag positive plasma were Infused into 257 patients. Since HB Ag positive blood products treated by BPL with UV produced no clinical hepatitis, it is evident that our treatment is efficacious against hepatitis virus agents

Immunoglobulin Levels in Serum of Normal Infants and Pre-School Children as Determined by Immunochemical Analysis

Standards for determining serum immunoglobulin (Ig) levels in infants and preschool children are now possible as a result of data compiled and presented in this paper. These can be compared with adult standards used in this hospital and presented in earlier issues of the MEDICAL JOURNAL. The Hospital\u27s laboratory technique is compared with other methods for measuring IgM, IgA and IgG serum levels

Quantitative Determination of C-Reactive Protein (CRP) by Micro-Double Diffusion Technic

C-reactive protein (CRP) determinations in serum have been evaluated by two methods: the capillary tube method (presently in use) and the double diffusion technic (a newly developed procedure standardized in this laboratory). Advantages of the double diffusion technic are (1) quantitation of CRP in milligrams per 100 ml of serum, (2) differentiation of CRP from non-specific precipitates often found in patients\u27 sera, and (3) increased sensitivity. A normal range of CRP levels has been established by analyzing serum from 750 supposedly healthy blood bank donors. Ninety-five percent of the donor population possess less than 1.0 mg of CRP per 100 ml of serum (53% are negative, 23% with trace quantities and 19% with 0.2-1.0 mg per 100 ml of serum). CRP serum levels above 1.0 mg per 100 ml are significant values for clinical interpretation

Il "flash of fireflies" e le sue costellazioni: studio di Six Feet of the Country e Jump and Other Stories di Nadine Gordimer

Lo studio portato avanti all'interno dell'elaborato permette di osservare e di verificare l’efficacia e la perfetta adattabilità di un genere letterario come la short story ad un contesto storico difficile e pieno di contraddizioni come quello sudafricano. Nonostante la compattezza e il rispetto delle norme richieste dal genere, i racconti analizzati appaiono tutti come piccole pennellate di colore che l’autrice, con grande abilità, è riuscita ad amalgamare al fine di racchiudere in due quadri ben distinti tra loro tutta l’eterogeneità che caratterizzava il suo paese. Le due raccolte prese in considerazione, Six Feet of the Country e Jump and Other Stories, consentono di confrontare due diversi periodi della storia sudafricana e, al contempo, di verificare il percorso di crescita artistica ed epistemologico della scrittrice
