A New Approach to Plane Failure of Rock Slope Stability Based on Water Flow Velocity in Discontinuities for the Latian Dam Reservoir Landslide

Journal of Mountain Science 2011年第2期8卷 124-130页

The stability of slopes is always of great concern in the field of rock engineering. The geometry and orientation of pre-existing discontinuities show a larger impact on the behavior of slopes that is often used to describe the measurement of the steepness, incline, gradient, or grade of a straight line. One of the structurally controlled modes of failure in jointed rock slopes is plane failure. There are numerous analytical methods for the rock slope stability including limit equilibrium, stress analysis and stereographic methods. The limiting equilibrium methods for slopes under various conditions against plane failure have been previously proposed by several investigators. However, these methods do not involve water pressure on sliding surfaces assessments due to water velocity and have not yet been validated by case study results. This paper has tried to explore the effects of forces due to water pressure on discontinuity surfaces in plane failure through applying the improved equations. It has studied the effect of water flow velocity on sliding surfaces in safety factor, as well. New equations for considering water velocity (fluid dynamics) are presented. To check the validity of the suggested equations, safety factor for a case study has been determined. Results show that velocity of water flow had significant effect on the amount of safety factor. Also, the suggested equations have higher validity rate compared to the current equations.

Background: Inflammatory bowel disease (IBD) is associated with increased morbidity and incident of colon cancer;however its etiology is still unclear. Currently, one of the most probable pathogenesis patterns is increased permeability of bowel membrane and it seems that oxidative stress plays an important role in this pathway. This study was done to assess the pro-oxidant antioxidant balance (PAB) in these patients. Materials: This was a cross sectional study of 2 groups including 50 patients with diagnosed IBD and 50 healthy controls. Patients were selected purposively from those referring to adult gastroenterology clinic in 2013. SPSS (ver11.5) has been. A P value < 0.05 was regarded as statistically significant. Results: Mean PAB in patients and controls group was 119.98 ± 38.98 HK unite and 52.67 ± 22.80 HK unite, respectively, (P value < 0.001). PAB mean in ulcerative colitis patients was 120.60 ± 33.90 HK unite and in CD patients was 118.20 ± 45.99 HK unite, and showed no significant difference (P value = 0.85). PAB and MDA could detect healthy subjects from IBD patients with sensitivity more that 90% and specificity more than 84%. Conclusion: PAB shifted to pro-oxidants in IBD patients;moreover this shift was unrelated to disease type. These tests could use as screening test.

Invasive candidiasis(IC) bears a high risk of morbidity and mortality in the intensive care units(ICU). With the current advances in critical care and the use of widespectrum antibiotics, invasive fungal infections(IFIs) and IC in particular, have turned into a growing concern in the ICU. Further to blood cultures, some auxil-iary laboratory tests and biomarkers are developed to enable an earlier detection of infection, however these test are neither consistently available nor validated in our setting. On the other hand, patients' clinical status and local epidemiology data may justify the empiric antifungal approach using the proper antifungal option. The clinical approach to the management of IC in febrile, non-neutropenic critically ill patients has been defined in available international guidelines; nevertheless such recommendations need to be customized when applied to our local practice. Over the past three years, Iranian experts from intensive care and infectious diseases disciplines have tried to draw a consensus on the management of IFI with a particular focus on IC in the ICU. The established IFI-clinical forum(IFI-CF), comprising the scientific leaders in the field, has recently come up with and updated recommendation on the same(June 2014). The purpose of this review is to put together literature insights and Iranian experts' opinion at the IFI-CF, to propose an updated practical overview on recommended approaches for the management of IC in the ICU.
