Audible and infrasonic noise levels in the cabins of modern agricultural tractors — Does the risk of adverse, exposure-dependent effects still exist?

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2013
Introduction: The agricultural tractor is one of the most commonly used vehicles on farms and one of the most prominent sources of noise. This article presents an exemplary assessment of the audible and infrasonic noise levels in the cabins of selected ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

On the solution of Nevanlinna Pick problem with selfadjoint extensions of symmetric linear relations in Hilbert space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
The representation of Nevanlinna Pick Problem is well known, see [7], [8] and [11]. The aim of this paper is to find the necessary and sufficient condition for the solution of Nevanlinna Pick Problem and to show that there is a one-to-one correspondence ...

Triple Operators of Order n on a Hilbert Space

open access: yesTikrit Journal of Pure Science, 2018
In this paper, we introduce a new class of operators on a complex Hilbert space  which is called triple operators of order n. An operator  is called triple operator of order n if  where  is the adjoint of the operator .

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Operation Leyte – operational fires

open access: yesSecurity and Defence Quarterly, 2018
<i>Operational fires are one of most important functions in a synergy effect with other operational functions that contribute to the achievement of targeted operational goals. The main operational goal of the American takeover of the Philippines was cutting Japan’s supply lines.
