We study the Λ(1520) resonance in a coupled channel approach involving the πΣ(1385), KΞ(1530), ¯ KN and πΣ channels. Implementing unitarity in coupled channels, we make an analysis of the relative importance of the different mechanisms which contribute to the dynamical structure of this resonance. From experimental information on some partial wave amplitudes and constraints imposed by unitarity...

This paper empirically analyzes a particular type of notes observed in securitization transactions: combination notes. Combination notes are formed by combining parts of two or more tranches of securitization transactions, where one part usually consists of a share of the first loss piece. It is analyzed whether combination notes are purely demand driven, or whether combination notes also appea...

We discuss damping of the collective rotational motion in A ∼ 150 superdeformed nuclei by means of a shell model combining the cranked Nilsson mean-filed and the surface-delta two-body residual force. It is shown that, because of the shell structure associated with the superdeformed mean-field, onset energy of the rotational damping becomes Ex ∼ 2 − 3 MeV above yrast line, which is much higher ...

Panitumumab is an anti-EGF receptor (EGFR) antibody approved for use in treatment of chemotherapyrefractory colorectal cancers lacking K-RAS mutations. Despite overall response rates approximating 10%, no marker predictive of clinical benefit has been identified.We describe a chemotherapy-refractory patientwhose clinical condition necessitated rapid identification of an effective agent in whom ...

2014 The paramagnetic Fe(I) electron reservoir sandwich ~5-C5H5Fe(I) ~6-C6(Me)6, its oxidized monocationic diamagnetic form and related diamagnetic ~5-C5H5Fe (cyclohexadienyl) complexes have been studied by Mössbauer spectroscopy on powders and aligned crystals. Spectra under high magnetic field were recorded for powders. On the basis of X-ray data I.E.H.T. MO calculations were performed and ga...

Males have dominated medicine for many centuries. Females could not appear in the medical history equally till the end of the 18th century; although they always have been in medicine as healers. It is worth mentioning that first illustrations indicating female surgeons were found in the book written in Turkish by Serefeddin Sabuncuoglu in the 15th century; while Europe was newly waking up from ...

The newest progress on the study of the strangeness in the proton and in the lowest negative parity nucleon excited state N * (1535) is reviewed. Implications on the internal quark structure of the proton, N * (1535) and other baryons are discussed. The diquark cluster picture for the 5-quark components in baryons gives a natural explanation not only to the empirical indications for a positive ...

The biggest agricultural sector that contributes to the Malaysian economy is the oil palm industry. The effluent generated during the production of crude palm oil known as palm oil mill effluent (POME). POME undergoes anaerobic treatment that requires long retention time and produces large amount of methane that consequently contributes to global warming. In this study, an isolated bacteria was...

The focus of this study was the empirical modelling high-speed bearings life and failure modes a through-flow universal motor. An approach used facilitating predictions through-range various conditions. model estimates bearing for survival probability 50% – L50. It influences parameters such as temperature, speed factor, equivalent load, grease fill amount, type oil, cage, seals, tolerance clas...
