Monitoring of environmental gases is necessary to understand the complex processes governing global warming and the impact of pollutant emissions related to human activity. Diode-laser-based spectroscopic techniques, being robust and affordable, have a great potential to become an industrially well-established technology for environmental sensing. This thesis deals with the further development of

This study aimed to find out how the insulation of the footwear changes over one week of use. A thermal foot model with 8 measuring zones and 5 “sweat glands” was used for tests. A thin sock was donned on the model to allow better water distribution all over the foot surface. Four boots were tested over a period of 5 days. Each day was divided into 9 hour measurement period and 15 hour conditionin

A system for electrostatic on-demand beam excitation in PIXE analysis has been built and carefully tested. Significantly increased count rate capability without any need for corrections for electronic dead time and with less target deterioration makes the system superior to a traditional system with electronic pile-up rejection. By adding a fast external electronic pulse pile-up rejection system,

Bone mineral density (BMD) and soft tissue composition were measured by dual energy X-ray absorptiometry (DXA) 3-4 years apart in 273 men and women aged 23-90. We found different rates of BMD loss in different skeletal regions. There were also different rates of BMD loss in different regions within the hip. Average rates of loss for male subjects 50 years of age and above for BMD total body were 0

This report describes a silicon-tungsten electromagnetic calorimeter used to determine some beam properties and luminosity in the DELPHI experiment at LEP. The polar angular range covered by this detector is 5–8 mrad, which allows the detection of a Bhabha rate about 10 times the rate of produced Z particles at the peak cross section.

According to the European prestandard ENV 342:1998, the thermal insulation of cold-protective clothing is measured with a thermal manikin. Systematic studies on the reproducibility of the values, measured with different types of clothing on the commonly used standing and walking manikins, have not been reported in the literature. Over 300 measurements were done in 8 different European laboratories

Artikeln, som innehåller en allmän översikt över bibeltolkningens historia samt principiella reflektioner kring förhållandet mellan den kristna församlingens bibeltolkning och den historisk-kritiska bibelforskningen, är så gott som identisk med en artikel som publicerades på danska 1997.

Phenotypic plasticity may enable organisms to optimize their phenotypes in environments that are heterogeneous over time or space. For example, inducible defenses are favored for prey populations faced with variable predation risk. We studied the impact of brook trout (Salvelinus fontinalis) on the development of defensive morphological characters in larvae of the mayfly, Drunella coloradensis, bo

We use Exel's C*-crossed products associated to non-invertible dynamical systems to associate a C*-algebra to arbitrary shift space. We show that this C*-algebra is canonically isomorphic to the C*-algebra associated to a shift space given by Carlsen [Cuntz–Pimsner C*-algebras associated with subshifts, Internat. J. Math. (2004) 28, to appear, available at arXiv:math.OA/0505503], has the C*-algeb

Popular Abstract in Swedish Avhandlingens ämne är den mezuzah, en kapsel med texter ur 5 Mosebok, som bör fästas på dörrposterna i ett judiskt hem, i uppfyllande av budet i 5 Mos. 6:9/11:21: "och du skall skriva dem [dessa ord] på dörrposterna i ditt hus och på dina portar". Genom en översikt över rabbinska texter vilka behandlar budet att fästa en mezuzah på dörrposterna i hemmet inventeras de föThe present study deals with different aspects of the mitsvat mezuzah in Rabbinic literature from the first to the sixteenth centuries, with some emphasis on the medieval sources. Through a charting of statements regarding the mezuzah as an object, and the mitsvat mezuzah and its fulfilment, an overview is given of the development of the mezuzah and the perception of it. Special attention is given

A method for evaluating chloride binding capacity of concrete was proposed based on the adsorption from solution and chloride binding isotherms of OPC pastes and mortars with water-cement ratio 0.4, 0.6 and 0.8. The experimental results show that the chloride binding capacity of concrete strongly depends on the content of CSH gel in the concrete, regardless of the water-cement radio and the additi

Lipolytic enzyme production of 150 isolated strains from samples of Lake Bogoria (Kenya) was examined. Among these, fifteen isolates were selected on the basis of their lipolytic activities and subjected to morphological and 16S rRNA gene sequencing analyses for their identification. All the microorganisms have been selected under culture conditions with pH ranges between 7-10 and temperatures of

This thesis analyses a contemporary debate on the Islamization of science. The four persons discussed here are individuals belonging to a Muslim intellectual elite: the French convert and physician Maurice Bucaille, the Persian-American scholar Seyyed Hossein Nasr, the British-Pakistani author Ziauddin Sardar and the Arab-American scholar Ismail Raji al-Faruqi. They represent four positions in the

A model of a cross-linked polyelectrolyte gel has been examined using Monte Carlo simulations. The simple model contained a charged defect-free network represented by linked charged beads and explicit counterions. Pressure-density relations for the polyelectrolyte gel, a corresponding non-ionic polymer gel, and several partly or fully degraded gels have-been determined. The polyelectrolyte gel dis
