THE outstanding acid-base change associated with extracorporeal circulation in cardiac surgery has been demonstrated to be metabolic acidosis, which has been variously reported to occur during perfusion or in the postoperative period.1 4 Since thoracic operations other than cardiac are known to produce marked changes in acid-base balance,5-7 intensive serial study of patients during openheart s...

This paper compares the performance of Pilot Tone Aided (PTA) and Pilot Symbol Aided (PSA) BPSK, QPSK, 8QAM, 16QAM, 32QAM and 64QAM over a narrowband radio channel. This set of modems is capable of achieving 14, 28, 48, 56, 70 and 84 kbit/s respectively in a 20 kHz channel bandwidth. Computer simulations in a Rayleigh fading channel show that PTA modems have almost the same performance as PSA m...

This paper presents an approach to the recognition of noisy patterns. We assume that learned concept descriptions contain noisy components. These descriptions can be optlmizcd to gain bener performance through the elimination of some less signilicant noisy componenls. Parametric conlrol of such an oplimization. however, is very difficult and a parameter value has 10 be found Ihrough the trainin...

Crystal engineering concept has been utilized to modify the physico-chemical parameters of a naturally occurring alkaloid, quinine sulphate, by exploring its H-bond interactions to generate different forms. Quinine sulphate is found to exist in four different crystal forms. The Forms I and II depict endo/exo events suggesting conversion of metastable low melting forms to higher melting and stab...

Pseudomonas aeruginosa (PA) and Burkholderia ambifaria (BA) are two opportunistic Gram negative bacteria and major infectious agents involved in lung infection of cystic fibrosis patients. Both bacteria can develop resistance to conventional antibiotherapies. An alternative strategy consists of targeting virulence factors in particular lectins with high affinity ligands such as multivalent glyc...

The present review reports the prevalence studies carried out in bovine cryptosporidiosis in European countries in the last decade, including the molecular background when available. In foreground, the distribution of Cryptosporidium species, genotypes and C. parvum subtype families (alleles) in cattle are described in the twenty countries where molecular studies have been conducted. Surveys ca...
