INTRODUCTION The role of chest compression fraction (CCF) in resuscitation of shockable out-of-hospital cardiac arrest (OHCA) is uncertain. We evaluated the relationship between CCF and clinical outcomes in a secondary analysis of the Resuscitation Outcomes Consortium PRIMED trial. METHODS We included patients presenting in a shockable rhythm who suffered OHCA prior to EMS arrival. Multivaria...

The methodology to estimate residual parametric common cause failure (CCF) probabilities consists of the selection of the data source, source plants, source systems and component type, failure mode, assessment of the impact vectors, determination of equivalent observations, calculation of CCF rates of different multiplicities with uncertainties using an empirical Bayes estimation method and fin...

background: lactic acid bacteria (lab) isolated originally from sourdough are probably the best candidates as biopreservatives, because they are well adapted to the non-aseptic conditions in sourdough fermentation. the aim of the present study was to study antifungal properties of a dominant endogenous lab isolated from whole barley sourdough. methods: whole barley flour from a mixture of barle...

background: we sought to determine the frequency of the risk factors for congestive cardiac failure (ccf) in a tertiary care hospital in peshawar, pakistan. methods: this retrospective, observational study was conducted in the department of cardiology, postgraduate medical institute, lady reading hospital peshawar, from march 2005 to september 2007. relevant information regarding the risk facto...

Interlocking Paving Blocks (IPB) are, nowadays, a widely used construction material. As result of the surge in demand for IPBs, alternative materials have been investigated to be IPBs. This study strength and durability characteristics (compressive strength, split tensile density, water absorption, skid resistance, abrasion resistance) IPBs presence (waste materials) crumb rubber (CR) coconut c...

We study the fundamental problem of learning the parameters of a high-dimensional Gaussian in the presence of noise — where an ε-fraction of our samples were chosen by an adversary. We give robust estimators that achieve estimation error O(ε) in the total variation distance, which is optimal up to a universal constant that is independent of the dimension. In the case where just the mean is unkn...

The purpose of this study was to investigate the recruitment pattern of deep and superficial neck flexors evoked by three different cervical flexion exercises using muscle functional MRI. In 19 healthy participants, transverse relaxation time (T2) values were calculated for the longus colli (Lco), longus capitis (Lca), and sternocleidomastoid (SCM) at rest and following three exercises: convent...

INTRODUCTION Carotico cavernous sinus fistula (CCF) is an abnormal communication between the carotid artery and the cavernous sinus and is classified angiographically as dural or direct. Spontaneous CCF is a dural arterio-venous fistula at the cavernous sinus which is different from traumatic CCF or CCF associated with a ruptured aneurysm at the cavernous internal carotid artery. Cerebral angio...
