Performance criteria, such as efficiencies and coefficients of performance, for energy systems, are commonly used but often without sufficient understanding and consistence. The situation becomes particularly incoherent when simultaneous energy interactions of different types, such as work, heating and cooling, take place with a system. Also, the distinction between exergy and Second Law effici...

caused no anxiety, but the nurse noticing a sudden change in the patient's appearance, sent for the Resident, Dr Kerr, who, recognising the serious condition, summoned me by telephone. When I saw the patient at 5 p.m. she was collapsed, ashy grey in appearance, and covered with cold, clammy sweat; pulse 128. P.V. cervix barely admitted two fingers, membranes unruptured, slight uterine haemorrha...

This report describes a case of spontaneous fibroblastic osteosarcoma in the humerus of a lion from a private park in Perugia, Italy. The tumor had an irregular, smooth, brown surface and a generally firm, rubbery consistence with gritty to hard areas interspersed. The mass was poorly vascularized with areas of necrosis at the periphery. The cut surface showed a multilobulated mass that had bre...

We study a least squares estimator b θT for the Ornstein-Uhlenbeck process, dXt = θXtdt+σdB H t , driven by fractional Brownian motion B H with Hurst parameter H ≥ 1 2 . We prove the strong consistence of b θT (the almost surely convergence of b θT to the true parameter θ). We also obtain the rate of this convergence when 1/2 ≤ H < 3/4, applying a central limit theorem for multiple Wiener integ...

Numerous experiments dealing with measuring of changes in human physiology due to mental stress are reported. In these researches, a stimulus is commonly employed to mentally, emotionally or cognitively affect the human subject and hers/his perception, resulting in changes in physiology. When evaluating such experiments from the metrology perspective, there is a clear lack of consistence and kn...

Posterior glottic stenosis or interarytenoid fibrous adhesion is uncommon and has sometimes been misdiagnosed as cord paralysis. Laryngoscopy and laryngeal electromyography studies are the two main diagnostic aids. We present the case of a 63-year-old man under endotracheal intubation during 10 days after a cardiac procedure who was evaluated in our department for persistent dysphonia. The lary...

Heat Shock Protein 90 was a key molecular chaperone involved in the proteome stability maintenance and its interference in many signaling networks associated with cancer progression, makes it of an important target for cancer therapeutics. The present study aimed to identify potential lead molecule among the selected heterocyclic compounds against Human Hsp90 (PDB: 1YET) through docking using G...

This paper deals with the problem of speech waveform polarity. As the polarity of speech waveform can influence the performance of pitch marking algorithms (see Sec. 4), a simple method for the speech signal polarity determination is presented in the paper. We call this problem peak/valley decision making, i.e. making of decision whether pitch marks should be placed at peaks (local maxima) or a...

This article presents a framework for the development of hypermedia systems, based on systematic modelling approaches. These introduce models at three abstraction levels (conceptual, navigation and presentation). An objectoriented approach, UWE, proposing UML extensions was adopted. The work described in this paper reports a solution for an integrated and consistent translation of those models ...
