Abstract. The glacier coverage in the Caucasus Mountains underwent considerable changes during last decades. In some regions, observed reduction area is comparable to those European Alps and extent of supra-glacial debris increased on many glaciers. Only a few glaciers are monitored regular basis, while for most areas no continuous field measurements available. this study, regional differences conditions melt with special focus covered tongues well-studied Adyl-su basin northern slope...
A new method to determine the spin tune is described and tested. In an ideal planar magnetic ring, tune-defined as number of precessions per turn-is given by ν(s)=γG (γ Lorentz factor, G gyromagnetic anomaly). At 970 MeV/c, deuteron spins coherently precess at a frequency ≈120 kHz in Cooler Synchrotron COSY. The deduced from up-down asymmetry deuteron-carbon scattering. time interval 2.6 s, was determined with precision order 10^{-8}, 1×10^{-10} for continuous 100 s accelerator cycle. This...
We observe a deuteron beam polarization lifetime near 1000 s in the horizontal plane of magnetic storage ring (COSY). This long spin coherence time is maintained through combination bunching, electron cooling, sextupole field corrections, and suppression collective effects current limits. record required for search an intrinsic electric dipole moment on at statistical sensitivity level approaching 10^{-29} e cm.
Based on the notion that local dark-matter field of axions or axionlike particles (ALPs) in our Galaxy induces oscillating couplings to spins nucleons and nuclei (via electric dipole moment latter and/or paramagnetic axion-wind effect), we establish feasibility a new method search for ALPs storage rings. previous work allows us maintain in-plane polarization stored deuteron beam few hundred seconds, perform first proof-of-principle experiment at Cooler Synchrotron (COSY) scan momenta near...
This paper presents the successful application of a phase-lock feedback system to maintain resonance condition radio frequency (rf) spin rotator (specifically, an rf Wien filter) with respect 120 kHz precession in Cooler Synchrotron (COSY) storage ring. Real-time monitoring and filter signal allows relative phase between two be stabilized at arbitrary setpoint. The compensates for deviations by adjusting and/or as needed. With this method, variation demand standard deviation...

Real time synchronization with radio (rf) solenoid made possible rotation out plane, yielding demonstration method manipulate polarization. In particular,...
The stable spin direction of polarized particles in a storage ring was determined first experimentally, through an accurate measurement the tune and its response to longitudinal magnetic fields.
It is well recognized that knowledge of allergic conditions suboptimal in primary care. The Primary Care Interest Group the European Academy Allergy and Clinical Immunology undertook an educational needs survey to better understand what they were how best meet them, care environment. An electronic questionnaire was devised distributed as widely possible. A total 2226 people from 63 countries opened e-questionnaire which 692 provided evaluable responses. In total, 81% medical doctors with 299...
The proposed method exploits charged particles confined as a storage ring beam (proton, deuteron, possibly $^3$He) to search for an intrinsic electric dipole moment (EDM) aligned along the particle spin axis. Statistical sensitivities could approach 10$^{-29}$ e$\cdot$cm. challenge will be reduce systematic errors similar levels. adjusted preserve polarisation, initially parallel velocity, times in excess of 15 minutes. Large radial fields, acting through EDM, rotate polarisation from...

Time use survey is one of the fundamental, and most widely employed, research tools used to bring a gender perspective project planning. However, narrow interpretations time data can distort understanding how project-induced changes affect women men's well-being. This paper argues that application some central concepts capability approach strengthen scope as gendered planning tool, drawing on example "Alliances" rural economic development Georgia.
The proton analysing power in $\vec{p}p$ elastic scattering has been measured at small angles COSY-ANKE 796 MeV and five other beam energies between 1.6 2.4 GeV using a polarised beam. asymmetries obtained by detecting the fast ANKE forward detector or slow recoil silicon tracking telescope are completely consistent. Although results agree well with many published data MeV, also most recent partial wave solution this energy, higher lie above predictions of angles. An updated phase shift...
Abstract Although the relationships between brain structure and emotions may alter across life span, this relationship is of particular importance during aging when significant alterations in be manifested. Understanding structural–behavioral could not only provide a neurobiological basis these changes, but also suggest potential intervention. Since anxiety commonly observed population, we undertook study to determine extent behavioral manifestations as well associated ultrastructural...
A low-energy spin-physics program is being developed at the COSY storage ring. To support planned experimental activities, several tools for polarized beams and targets have been developed. The paper presents physics case readiness of setup its realization.
