Theory is presented that extends the analysis to signal correlation between any antennas in an array of elements. It is generalised to include non-identical elements and arbitrary load termination of passive antenna ports. The method is related to the power balance concept and based on the antenna impedance matrix.
The formerly grazed forest (utmark) was the dominant land use on most farms in southern Sweden until about 100 years ago. Here I describe the changed structure and tree species composition over time of the utmark on three farms owned by the church in the central part of Stenbrohult. In this area Carl Linnaeus spent his first 20 summers until 1728. The study is based on old forest management plans,
Aqueous gallium(III) citrate complexes have been studied in the 10(-2) M concentration range with extended X-ray absorption fine structure (EXAFS) and FTIR techniques. From EXAFS data, one mononuclear and one oligomeric species were identified at different Ga(III) to citrate ratios. The first shell of the mononuclear complex was found to be distorted, with average Ga-O bond lengths of 1.95 and 2.0
INTRODUCTION: Atrophic condition in the vagina and lower parts of the urethral tract are common in elderly women. From population based surveys it has been estimated that 40% or more of women over 60 complain of insufficient control of micturation. In addition, lower urinary tract infections are common in this age group and recurrent cystitis is a scourge for many women (1, 2). Vaginal problems su
The Multi-plume Aerosol dynamics and Transport (MAT) model has been developed to study the dynamics of the particle size distribution in urban environments. The MAT model uses a novel multi-plume scheme for vertical dispersion and routines of the aerodynamics models AERO3. It treats the processes: emission from a near ground source, dilution with background air, deposition, coagulation and condens
Let $T_\alpha$ be the class of functions meromorphic in the unit disk ${\bf D}$ such that $$\int_D{|f'(z)|^2\over (1+|f(z)|^2)^2}(1-|z|)^{1-\alpha}dx\,dy<\infty,\quad 0\leq\alpha<1.$$ It is known that $T_\alpha\subset N$, where $N$ denotes the Nevanlinna class of functions meromorphic in $\bold D$ and of bounded characteristic. Because every $f\in N$ is a quotient of two bounded functions, analy
Some known elementwise methods of PAA calibration are considered, without use of phase meas-urement apparatus. Features of these methods are described for the case of multi-channel phased array antennas (several hundreds or thousands of channels). Calibration algorithm is suggested for this case, it consists of antenna channels grouping, in-group channel calibration and, finally, mutual calibratio
A method which is simple, reliable, and rapid to use in clinical routine for basic dose calculation in total body irradiation (TBI) has been tested with 8 MV x-rays. The dosimetry follows, as far as possible, national and international recommendations for conventional radiotherapy. The dose rate at different locations and depths is calculated from the absorbed dose rate at dose maximum for a phant
A new high-spin superdeformed band has been discovered in Nd-140(60)80. It was populated in the Zr-96(Ca-48,4n) reaction and investigated using the EUROBALL gamma-ray spectrometer array. The band is observed in the approximate spin range of I=36 to 66. It is associated with shell gaps around Z=60 and at N=80 at large deformation. These gaps produce a pronounced minimum in the calculated total Rout
Artikeln belyser olika faser i Nietzsches komplexa förhållande till religionen och diskuterar ambivalensen i Nietzsches "dödförklaring" av Gud.
This chapter discusses different coals compared with respect to the extent of sulfur removal and jarosite formation when processed with A. brierleyi. All coals are of low-sulfur type with a sulfur content ranging from 0.6 % through 1.8 %. The efficiency of the microbial processing of coal depends on three factors––namely, the rate of sulfur removal, the extent of sulfur removal, and the formation
The construction of a magnetron-based source for neutral metal vapors is presented. The first photoelectron spectroscopy experiments with the source using synchrotron radiation at MAX-lab, Sweden are described. Photoelectron spectra of atomic copper, silver, and nickel are reported with an 80 meV resolution for Cu and Ag, previously not achieved in experiments using synchrotron light. (c) 2006 Ame
A model has been developed to predict the dissolution rate of a limestone slurry as a function of particle size distribution and limestone conversion. The model is based on basic mass-transfer theory and includes a factor allowing the flux of calcium ions from the limestone surface to vary with the fraction dissolved. Changes in the flux with the fraction dissolved have been reported to be caused
OBJECTIVE. To identify markers for late fetal death, a multicenter study was performed, based on routinely obtained data from maternal health care units. MATERIAL AND METHODS. Prospectively recorded data were obtained from maternal health care units belonging to five delivery units. In all, 233 consecutive cases of singleton pregnancy involving late fetal death (> or = 28 weeks) were identified be
Vascular smooth muscle phenotype is regulated by environmental factors, such as mechanical forces, which exert effects on signaling to differentiation and growth. We used the mouse portal vein in organ culture to investigate stretch-dependent activation of Akt, extracellular regulated protein kinase (ERK) and focal adhesion kinase (FAK), which have been suggested to be involved in the regulation o
A need for methods to assess fire risks in timber frame buildings lead to the development of FRIMMAB, a Fire Risk Index Method for Multi-storey Apartment Buildings. The main objective of this report is to evaluate this method against a different risk analysis method, in this case a standard QRA (quantitative risk analysis) based on an event tree. Four different multi-storey apartment buildings in
