A New Insight into the Stability of Precariously Balanced Rocks

چکیده
Abstract Large granitic boulders resting on steep slopes represent considerable safety hazards that largely depend the location of contact surface characterized by impression d , denoting parallel distance between and original rock surface. On other hand, this reflecting often convex nature platforms, cannot be measured precisely, so Factors Safety (FoS) computed with input may have significant uncertainties. Using geometric 3D analysis, here, we present concept computing FoS as a function admitting much more reliable estimate actual hazards. Beyond introducing functions, also identify all failure modes, some which not yet been investigated. We compute functions for boulder Pena do Equilibrio located in Spain. Our computations against sliding match earlier results. However, toppling torsion show latter critical. Since our methods are general, suggests phenomena, scarcely studied far, relevant to analyze stability natural boulders.

New insight into the clinico-histomycological aspects of onychomycosis and a review of the literature
Background: Onychomycosis (OM) is the infection of nails caused by a variety of fungi. As systemic antifungal treatment is necessary in the majority of patients, appropriate diagnostic techniques are important to ensure a correct diagnosis and treatment. Objective: This study was carried out to evaluate the clinical, mycological, and histological aspects of onychomycosis in detail. Methods: A c...
متن کاملNew Insight into the Relation between Adiponectin and Diabetes
Diabetes mellitus is a group of metabolic diseases. Insulin resistance is defined as a state that needs more insulin to get the biological effects achieved by a lower amount of insulin in the normal state. Several molecules which are secreted through adipocytes have been involved in insulin resistance and type 2 diabetes mellitus. Adiponectin as a 244 amino acid protein is exclusively expressed...
متن کاملNew Insight into the SAR of Pyrimido [4,5-b][1,4] Benzothiazines as 15-lipoxygenase Inhibitors
Objective(s): Recently we reported that the soybean 15-lipoxygenase (SLO) inhibitory activity of pyrimido[4,5-b][l,4]benzothiazines largely depends on the orientation of sulfur atom of thiazine core towards FeIII-OH in the active site pocket of the enzyme with subsequent oxidation of sulfur to sulfoxide. In this paper the results of a comparative study on the SLO inhibitory activities of the ...
متن کاملNew Insight into the Effect of Phototherapy on Serum Magnesium Level
Background: Jaundice is one of the most common findings in the neonatal period. In almost all the cases, neonatal jaundice occurs due to the elevated level of unconjugated bilirubin. Evidence is scarce regarding the association between magnesium and bilirubin levels in neonatal hyperbilirubinemia. The present study aimed to investigate serum magnesium levels before and after phototherapy.Method...
