Farmland prices, structural breaks and panel data

Previous time series evidence has indicated that farmland prices and cash rents are not cointegrated, a finding at odds with the present value model of farmland prices. We argue that this failure to find cointegration may be due to low power of tests and to the presence of structural change representing a shifting risk premium on farmland investments. To accommodate this possibility, we use panel

Identification of novel proteolytic forms of osteocalcin in human urine

In this study, we report the isolation and characterization of osteocalcin in human urine using mass spectrometry and N-terminal sequencing. Multiple proteolytic forms of osteocalcin were found, which consisted of 16-27 residues from the middle region of the molecule. Several fragments had residue Gly7 at the N-terminus and the most predominant was fragment 7-31. Additional fragments starting from

Migration of uncemented, long-stem femoral components in revision hip arthroplasty. A 2-8 year clinical follow-up of 45 cases and radiostereometric analysis of 13 cases

We reviewed after 48 (24-90) months the clinical results in 45 cases of revision hip arthroplasties where an uncemented, long-stem femoral prosthesis (BIAS, Zimmer) had been used. A subgroup of 13 cases was followed with radiostereometric analysis (RSA) for 2 years. 3/45 cases had been revised, another 12 had unsatisfactory pain scores. The median Harris score was 69 (26-99). 12/13 stems migrated;

Rotational Bands in 76Rb

High spin states in 76Rb were investigated via the reaction 40Ca(40Ca,3pn)76Rb at 128 MeV. The level scheme was established from γγ, γγγ and recoil-γ coincidences measured in the EUROGAM I array in combination with the Daresbury recoil separator. The known rotational bands were extended up to the excitation energy Ex≊9.2 MeV and spins Iπ=(21+) and (19-). The band head energies could be fixed by ma

An Integrated System-Level Design for Testability Methodology An Integrated System-Level Design for Testability Methodology

HARDWARE TESTING is commonly used to check whether faults exist in a digital system. Much research has been devoted to the development of advanced hardware testing techniques and methods to support design for testability (DFT). However, most existing DFT methods deal only with testability issues at low abstraction levels, while new modelling and design techniques have been developed for design at

Inducing and reducing false memories: A Swedish version of the Deese-Roediger-McDermott paradigm

Participants tend to falsely remember a nonpresented critical word after having studied a list of the word's primary associates. We present here a Swedish version of the Deese-Roediger-McDermott paradigm, which provides a tractable method of experimentally inducing and investigating such illusory memories. In Experiment 1 it was demonstrated that the constructed stimulus material induced highly re

Från guidad visning till shopping och förströdd tillägnelse: moderniserade villkor för ungdomars musikaliska lärande.

Popular Abstract in Swedish Under 1990-talet har från olika håll ställts krav på ett ökat elevinflytande över innehåll och arbetsformer i den allmänna skolan. Dessa krav har dels kommit från eleverna själva, dels kommit till uttryck i olika styrdokument. Att så har varit fallet ter sig ganska naturligt, eftersom den tidsanda i vilken vi lever är präglad av individualism. Ett antagande, som stöds aAbstract In the Swedish compulsory school system there is a trend towards increased student influence. School ideologists have for at least ten years strongly emphasised this issue. This tendency is in line with a more general direction in Western societies, which in many aspects has moved toward individualisation. Based on these developments, the main reason for undertaking the presents study was

Systematic screening of potential beta-cell imaging agents.

The beta-cell loss seen in diabetes mellitus could be monitored clinically by positron emission tomography (PET) if imaging agents were sufficiently specific for beta-cells to overcome the high ratio of non-beta-cell to beta-cell tissue in pancreas. In this report, we present a screening assay for identifying beta-cell-specific compounds that is based on the relative accumulation and retention by

Contractile properties of lymphatics from the human lower leg

Lower leg lymphatics, taken from seven volunteers, were investigated in vitro. Isometric contractions were induced by noradrenaline, 5-hydroxytryptamine (5-HT), prostaglandin F2 alpha (PGF2 alpha), and the thromboxane A2 (TXA2)-mimetic U-44069. Noradrenaline induced phasic contractions in 6 of 7 segments. The amplitude of the contractions were up to 100% of a previous K+ (124mM)-induced contractio
