This chapter discusses the preparation of stable radioiodinated polypeptide hormones and proteins using polyacrylamide gel electrophoresis. Radioactively labeled polypeptide hormones and proteins are widely used as tracers in radioimmunoassays and receptor studies. The peptide or protein is most easily labeled using iodination with 125I or 131I. The radioactive iodine is substituted in the tyrosin

We present an extension of the atomic frequency comb protocol that utilizes the Stark effect to perform noise-free, on-demand, control. An experimental realization of this protocol was implemented in the Pr3+:Y2SiO5 solid-state system, and a recall efficiency of 38% for a 0.8 μs storage time was achieved. Experiments were performed with both bright pulses as well as weak-coherent states, the latte

We report on the cytogenetic studies, performed in a routine cytogenetic laboratory between 1981 and 1986, on 428 subjects: 291 probands with non‐specific mental retardation, 101 first‐degree relatives of fra(X) positive patients and 36 non‐retarded patients, referred for other reasons. As a rule 50 cells, cultured in folate‐deficient medium were analysed. The results are compared with data collec

Naturally occurring phyllosilicate minerals such as talc and vermiculite in conjunction with n-tetra butyl ammonium bromide (TBAB) co-catalyst were found to be efficient in the coupling of CO2 with epoxides to form cyclic carbonates. The reaction was carried out in a pressurized autoclave reactor at moderate pressures of 10–35 bars and temperatures of 100–150 °C. The optimized catalyst system exhi

We study the radial migration of stars as a function of orbital action as well as the structural properties of a large suite of N-body simulations of isolated disc galaxies. Our goal is to establish a relationship between the radial migration efficiency of stars and their vertical action. We aim to describe how that relationship depends on the relative gravitational dominance between the disc and

In this chapter, the authors shift between two overlapping positions, of both “being wrapped up in it” (Lieutenant Pelly’s vignettes) as well as “being outside of it” (Frandsen’s theoretical vignettes). They use storytelling vignettes of Duncan Pelly’s deployment to Korea as a Human Resource officer of the US army, which is supplemented with theoretical vignettes designed to guide the reader to un

Seventy-two alcoholic patients (60 men and 12 women) were randomized into four groups who received psychiatric treatment (PT) or multimodal behavioural therapy (MBT), for either 1 or 2 years. PT was based on psychodynamic principles, and MBT is a cognitive-behavioural treatment. The patients accepting treatment had a mean age of 37 ± 9 years, and they were socially stable. There was no difference

Purpose of Review: This review outlines the scope of the problem in osteoporosis care and secondary fracture prevention and describes fracture prevention strategies, with a focus on the frail elderly. Recent Findings: Despite heightened awareness among patients and clinicians alike and the availability of efficacious anti-osteoporosis medications, osteoporosis is still underdiagnosed and undertrea

Ambulatory ECG recordings are frequently corrupted by artifacts caused by, e.g., muscle activity or moving electrodes, which complicates the analysis of f-waves and motivates signal quality assessment to improve the reliability of f-wave analysis. Although many methods have been developed for assessing the quality of ECG signals in general, no method deals specifically with f-waves. This study pro

The industrial symbiosis (IS) landscape is evolving at high speed. There is a growing interest in knowledge sharing and partnering, as is evident from the establishment of multiple IS networks at local and regional level. This article investigates the role of local governments in industrial symbiosis. It aims to build a theoretical framework explaining how local governments can reduce barriers to
