This paper examines the compressive strength of sodium silicate bonded cores for aluminum casting with different additives. Various materials are used as additives among which it is found that 5% sand size bauxite has the best effect on both gas strength and de-coring 98.5% silica content sand with 70-90 AFS No. with 4% sodium silicate is used. The results indicate that although very good colla...

Introduction Prediction of fluid responsiveness (FR) is a critical step in management of patients with septic shock. Using ultrasound in detection of inferior vena cava (IVC) diameters and collapsibility is established in mechanically ventilated patients; however its use in spontaneous breathing patients is still controversial [1]. Few studies reported a correlation between internal jugular vei...

In this paper we determine the threshold for d-collapsibility in the probabilistic model Xd(n, p) of d-dimensional simplicial complexes. A lower bound for this threshold p = ηd n was established in [?], and here we show that this is indeed the correct threshold. Namely, for every c > ηd, a complex drawn from Xd(n, c n ) is asymptotically almost surely not d-collapsible.

Ultrasound provides a rapid method of evaluating the emergency patient at the bedside by the treating physician. Besides being advantageous in eliminating or supporting a differential diagnosis in an emergency patient, bedside ultrasound can also rapidly evaluate physiology. This articles describes such a use of bedside ultrasound, the evaluation of the inferior vena cava size and collapsibilit...

During sedation and recovery the airway of children with obstructive sleep apnea is vulnerable to collapse. This vulnerability arises from both an inherent collapsibility of the pharyngeal airway in these children and a heightened sensitivity to sedative and anesthetic agents. Pharmacologic and nonpharmacologic support may be required to defend pharyngeal airway patency in children with obstruc...

Collapsibility of gypseous soils may cause excessive settlement and severe damage to engineering structures. Many improvement methods have been employed reduce the collapsibility these soils, such as by using physical or chemical additives. The improved has conventionally evaluated odometer test, which not accurately replicate field conditions because small size test specimens. In this research...

The concept of consistency has pervaded studies of the constraint satisfaction problem. We introduce two concepts, which are inspired by consistency, for the more general framework of the quantified constraint satisfaction problem (QCSP). We use these concepts to derive, in a uniform fashion, proofs of polynomial-time tractability and corresponding algorithms for certain cases of the QCSP where...

Objective: Fast and accurate detection of fluid balance in intensive care patients is special significance. Many different methods are used to determine the balance. In this study, we aimed medical unit using measurement inferior vena cava diameter pro-brain natriuretic peptide (proBNP). Patients Methods: admitted between September 2013 February 2014 were enrolled study. Inferior was measured w...

Abstract Goals of volume management are to accurately assess intravascular and extravascular predict response administration, vasopressor support, or removal. Data reviewed that support the following: 1) Dynamic parameters reliably guide administration may improve clinical outcomes compared static parameters, but some invasive only validated with mechanical ventilation without spontaneous breat...
