Background. Group A streptococcal (GAS) meningitis is rarely seen in the antenatal period, but it is associated with significant mortality. We present a case of a mid-trimester woman who developed fulminant meningitis following a rapid onset atypical presentation of infection with this organism. Case. A multiparous 23(+5)-week woman presented with a 10-day history of a non-productive cough asso...

In this paper, we study the geometry of cone-offs CAT(0) cube complexes over a family combinatorially convex subcomplexes, with an emphasis on their Gromov-hyperbolicity. A first application gives direct cubical proof characterization (strong) relative hyperbolicity right-angled Coxeter groups, which is particular case result due to Behrstock, Caprace, Hagen and Sisto. second acylindrical C ′ (...

This paper describes an uncertainty evaluation for the measurement of radial runout, axial runout and coning for axisymmetric measurement machine. An industrial axi-symmetric measurement machine was used which consisted of a rotary table and a number of contact measurement probes located on slideways. Type A uncertainties were obtained from a repeatability study of the probe calibration process...

Carbon dioxide has been used commercially to recover oil from reservoirs for more than 40 years. Currently, CO2 flooding is the second most applied enhanced oil recovery (EOR) process in the world behind steam flooding. Water alternating gas (WAG) injection has been a popular method to control mobility and improve volumetric sweep efficiency for CO2 flooding. Average EOR is about 9.7% with a ra...

In this paper, we combine separate works on (a) the transfer of infinitesimal rigidity results from an Euclidean space to the next higher dimension by coning [28], (b) the further transfer of these results to spherical space via associated rigidity matrices [19], and (c) the prediction of finite motions from symmetric infinitesimal motions at regular points of the symmetryderived orbit rigidity...

A new generalized optimum strapdown algorithm with coning and sculling compensation is presented, in which the position, velocity and attitude updating operations are carried out based on the single-speed structure in which all computations are executed at a single updating rate that is sufficiently high to accurately account for high frequency angular rate and acceleration rectification effect...

In this using paper a method is presented for the aerodynamic and structural analysis of a horizontal axis wind turbine using simplified methods. In the first part of the program the optimum rotor configuration for twist and chord is determined using the momentum and blade element theories for a rotor without coning or tilting and assuming zero drag average wind velocity. Then coning angle and ...

Carbon dioxide has been used commercially to recover oil from reservoir by enhanced oil recovery technologies for over 40 years. Currently, the CO2 flood is the second most applied enhanced oil recovery (EOR) processes in the world behind steam flood. Water alternating gas (WAG) injection has been a popular method to control mobility and improve volumetric sweep efficiency for CO2 flooding. The...
