A new high-throughput liquid chromatography / tandem mass spectrometry (LC-MS/MS) method for the quantification of Δ-tetrahydrocannabinol (THC) in suspect plant material and of its principal metabolite, 11-nor-9carboxy-Δ-tetrahydrocannabinol (THC-COOH), in human urine was developed and validated. The separation was performed on a Zorbax SB-C18 column under isocratic conditions using a mixture o...

The use of geothermal energy in Finland is restricted to the utilization of ground heat with heat pumps. This is due to the geological conditions as Finland is a part of the Fennoscandian (or Baltic) Shield. The bedrock is Precambrian covered with a thin (<5 m) cover of Quaternary sediments. Topography is subdued and does not easily produce advective re-distribution of geothermal heat by ground...

Heli Silvennoinen Burden of influenza in children Department of Pediatrics, Institute of Clinical Medicine, University of Turku Annales Universitatis Turkuensis, Medica–Odontologica, Turku, Finland, 2012 Background: Most children with influenza are treated as outpatients but, especially among young children, influenza-attributable illnesses often result in hospitalization. However, relatively s...

A 40 year old Pakistani woman presented with one month history of fever, night sweats, and progressive and painful swelling in the right side of the neck. She was febrile (temperature 38–40oC). Right deep cervical, occipital, and jugulodiagastric lymph nodes were palpable, firm, and tender. Save for a moderately severe asymmetrical arthralgia of right wrist, shoulder and proximal interphalangea...

Biosurfactants are surface –active amphipathic molecules produced by a plethora of microorganisms. The aim of the present study was production of biosurfactants from some bacterial isolates for bioremediation of crude oil spills. Twenty five bacterial isolates were isolated from twenty crude oil contaminated soils located in repairing cars stations in Khorma governorate,Taif, Kingdom of Saudi A...

the utilization of substitued dienes with electron-donor groups and under high pressure conditions, induces the dienophilic character of 1-nitronaphtalene in Diels-Alder reactions, giving the products with and without the nitro-group, the yield depending on the nature of the dienes substituent groups. Introduction The Diels-Alder reaction has been subject of extensive studies for both theoretic...

High pressure processing (HPP) is becoming of increasing importance in the food industry as it offers the opportunity to obtain minimally processed food products with increased safety and extended shelf-life. A sound knowledge of the effects of high pressure on meat attributes is necessary for a successful implementation of HPP in the meat industry. The aim of this work was to determine the eff...

The effect of body warming and cooling on the heart and breathing rates has been studied in the agamid lizard Uromastyx microlipes. Electrocardiograph (ECG) of Uromastyx microlipes consists of P, QRS, and T components similar to those in mammals. Heart rate increases with body temperature. During warming the heart rate ranged from 7-134 beat/min, while during cooling ranged from 2-73 beat/min. ...

As commercial-grade silicon carbide (SiC) power electronics devices become available, the application of these devices at higher temperatures or frequencies has gained interest. This paper contains temperature-dependent loss models for SiC diodes and JFETs and simulations for different power converters that are useful for predicting the efficiency of these converters. Additionally, tests to cha...
