The vapour pressure and the thermal stability of liquids are important material properties. For high boiling organic and ionic liquids (ILs), the determination of these properties is laborious and it is not easy to discriminate between evaporation and thermal decomposition. In this work, a simple but accurate method is presented to determine the parameters of decomposition and evaporation by th...

Drying of solid particles is generally divided into three periods: a short initial heating period, a constant drying rate period, and a falling drying rate period. Drying in a fixed under various drying conditions was experimentally studied. The main goals of the measurements were to calculate the heat transfer coefficient based on the measured values, and to evaluate the validity of the consta...

Introduction: The Martian poles present special challenges for human scientific expeditions that bear similarities to operations in terrestrial polar regions. These challenges include mobility on snows and ices, the problem of accommodation in the deep field, methods for the use of local resources and problems of station maintenance. Because the polar regions are dynamic, substantial volatile s...

Background/Objective Impingement syndromes are a common cause of shoulder pain in overhead athletes. Anterior internal impingement is a recently suggested mechanism for activity-related pain of the shoulder. Impingement syndromes were initially described to occur due to repetitive or excessive contact between the rotator cuff and other structures in the shoulder. Methods This is a retrospecti...

Benign laryngotracheal tumours of the minor salivary glands are rare,1 so experience in their treatment and evolution is limited. Indeed, we did not find any evidence of previous publication of a case of monomorphic adenoma in a subglottic location (PubMed, keys words: subglottic/laryngotracheal adenoma; larynx salivary adenoma; monomorphic/basal cell adenoma. Period covered: 1979–2012. Updated...

The heat and mass transfer phenomena that occur in beds of ventilated hygroscopic porous media are coupled. This results in two transfer waves traversing bulks of porous medium that initially have a uniform temperature and moisture content, and that are subsequently ventilated with air that is not in thermodynamic equilibrium with the solids. The more rapidly travelling wave is known as a tempe...

A semi-empirical model for pool boiling over porous surfaces is presented. The pressure drop across the porous surface is estimated using Darcy 's law. The signi®cance of the latent heat ̄ux contribution for highly porous surfaces is examined. Two nucleation factors are de®ned and correlated in terms of measurable quantities using literature data. An expression for the total heat ̄ux in terms o...

• Increasing the volumetric concentration of PFP led to an increase in size lipid-coated NDs. sonication intensity and time a decrease ND size. The coating layer can be labelled with lipophilic fluorophores without affecting overall NDs were stable at 4 °C for one week, 37 110 min. Ultrasound (0.5 MHz, 2–4 MPa) caused vaporisation within tissue-mimicking phantom. Liquid perfluorocarbon nanodrop...

Toluic acid isomers are widely used as a chemical intermediate in manufacturing of dyes, pharmaceuticals, polymer stabilizers, insect repellent and other organic synthesis. The aim of present study was to evaluate the impact of biofield treatment on physical, thermal and spectroscopic properties of ortho isomer of toluic acid (OTA). The OTA sample was divided into two groups, served as control ...

OBJECTIVES To determine the clinical effectiveness and cost utility of procedures alternative to TURP (transurethral resection of the prostate) for benign prostatic enlargement (BPE) unresponsive to expectant, non-surgical treatments. DATA SOURCES Electronic searches of 13 databases to identify relevant randomised controlled trials (RCTs). REVIEW METHODS Two reviewers independently assessed...
