The Partisan Politics of New Social Risks in Advanced Postindustrial Democracies: Social Protection for Labor Market Outsiders
Advanced postindustrialization generates numerous challenges for the European social model. Central among these challenges is declining income, unstable employment, and inadequate training of semi- and unskilled workers. In this chapter, I assess the partisan basis of support for social policies that address the needs of these marginalized workers. I specifically consider the impacts of postindustrial cleavages among core constituencies of social democratic parties on the capacity of these parties to pursue inclusive social policies. I argue – and find support for in empirical analyses – that encompassing labor organization is the most important factor in strengthening the ability of left parties to build successful coalitions in support of outsider-friendly policies. I go beyond existing work on the topic by considering the full array of postindustrial cleavages facing left parties, by more fully elaborating why encompassing labor organization is crucial, and by considering a more complete set of measures of outsider policies than extant work. I compare my arguments and findings to important new work that stresses coalition building and partisan politics but minimizes the role of class organization
A review of the evolution of robotic-assisted total hip arthroplasty.
INTRODUCTION: Total hip arthroplasty (THA) is currently a very successful operation but continues to evolve as we try to perfect techniques and improve outcomes for our patients. Robotic hip surgery (RHS) began with the 'active' ROBODOC system in the 1980s. There were drawbacks associated with the original ROBODOC and most recently, the MAKO robot was introduced with early promising results. AIM: The aim of this paper is to provide an up-to-date review surrounding this area and discuss the pros and cons of this technique. METHODS: A literature review searching Medline, Embase, Ovidsp, Cochrane library, pubmed database and google scholar was performed searching keywords including: 'Robotic hip surgery', 'Robotic orthopaedic surgery', 'Computer assisted hip surgery', 'robotic arthroplasty', and 'computer assisted orthopaedic surgery'. CONCLUSION: Robotic hip surgery aims to tackle the limitations of the human factor in surgery by promising reproducible and reliable methods of component positioning in arthroplasty surgery. However, as orthopaedic surgeons, we must critically appraise all new technology and support the use providing there is sound robust evidence backing it

Discovery of a 0.02 Hz QPO feature in the Transient X-ray Pulsar KS 1947+300
We report the discovery of Quasi Periodic Oscillations (QPO) at 0.02 Hz in a
transient high mass X-ray binary pulsar KS 1947+300 using {\em RXTE}-PCA. The
QPOs were detected during May-June 2001, at the end of a long outburst. This is
the 9th transient accretion powered high magnetic field X-ray pulsar in which
QPOs have been detected and the QPO frequency of this source is lowest in this
class of sources. The unusual feature of this source is that though the
outburst lasted for more than 100 days, the QPOs were detected only during the
last few days of the outburst when the X-ray intensity had decayed to 1.6% of
the peak intensity. The rms value of the QPO is large, with a
slight positive correlation with energy. The detection of QPOs and strong
pulsations at a low luminosity level suggests that the magnetic field strength
of the neutron star is not as high as was predicted earlier on the basis of a
correlation between the spin-up torque and the X-ray luminosity.Comment: Accepted in MNRA
High-sensitivity measurement of He 3 − He 4 isotopic ratios for ultracold neutron experiments
Research efforts ranging from studies of solid helium to searches for a neutron electric dipole moment require isotopically purified helium with a ratio of 3 He to 4 He at levels below that which can be measured using traditional mass spectroscopy techniques. We demonstrate an approach to such a measurement using accelerator mass spectroscopy, reaching the 10 - 14 level of sensitivity, several orders of magnitude more sensitive than other techniques. Measurements of 3 He / 4 He in samples relevant to the measurement of the neutron lifetime indicate the need for substantial corrections. We also argue that there is a clear path forward to sensitivity increases of at least another order of magnitude

Thermal Conversion of Methane to Acetylene
This report describes the experimental demonstration of a process for the direct thermal conversion of methane to acetylene. The process utilizes a thermal plasma heat source to dissociation products react to form a mixture of acetylene and hydrogen. The use of a supersonic expansion of the hot gas is investigated as a method of rapidly cooling (quenching) the product stream to prevent further reaction or thermal decomposition of the acetylene which can lower the overall efficiency of the process
