Analysis and settlement evaluation of an end-bearing granular pile with non-linear deformation modulus

granular pile with L/d = 40, the effect of non-homogeneity on the settlement influence factor is negligible: due to the presence of the bearing strata at great depth, very less load is transferred to the lower reaches of the long homogeneous (α = 0) compressible granular pile. The same phenomenon had been reported by Mattes and Poulos [ 1 ] and Scott [ 16 ]. Consequently, even if the modulus of deformation of the granular pile is higher (α > 0) due to non-homogeneity, its effect on reduction in settlement would be very little. For the same reason, settlements of long

Stone Columns - Determination of the soil improvement factor

Stone Columns - Determination of the soil improvement factor

A stone column is one of the soil stabilizing methods that is used to increase strength, decrease the compressibility of soft and loose fine graded soils, accelerate a consolidation effect and reduce the liquefaction potential of soils. The columns consist of compacted gravel or crushed stone arranged by a vibrator. This paper deals with Priebe's theory (1976) on the design of an improvement factor, which belongs among the most used analytical methods and also describes the numerical and laboratory models of stone columns. The improvement factors calculated from numerical and laboratory models are compared with the improvement factors resulting from Priebe's theory.

Sambucus nigra (L.) liophylised extract as source of direct compression tablets obtaining

Abstract

The aim of this paper is the valorization of a 10 % anthocyanins elderberries lyophilized extract standardized as cyanidin-3-glucoside in lozenges obtained by direct compression and quality lozenges evaluation according to Romanian and European pharmacopoeia tests. The resulting lozenges with a 600 mg concentration of a 10 % anthocyanins elderberries lyophilized extract standardized as cyanidin-3-glucoside were evaluated using the following tests: appearance and mass uniformity (20 lozenges) disintegration time (6 lozenges), hardness (10 lozenges), anthocyanins assay expressed as cyanidin-3-glucoside using a spectrometric method at pH differential values. The results are expressed as means± standard deviation. The tablets for the two formulas have the same appearance (flat, round, colored in purple - red, non gritty), the dimensional characteristics (height, thickness) are different, average mass complies the pharmacopoeia standards. The lozenges from formula 2 have a higher resistance (215.7 N) and a lower disintegration time (11 min.) according to the official recommended values, due to differences from carbopol polymers differences in properties at the same concentration used in the two formulas. Using the direct compressible products described in this study, the direct compression technique can be easily applied for the manufacture of lozenges, thus ensuring their stability by avoiding heat and humidity factors during the manufacturing process. The resulting lozenges from formula 1 respect the quality specifications provided by the Romanian Pharmacopoeia Xth edition, the European Pharmacopoeia. The lozenges presented a high mechanical resistance (110 N) and a good disintegration time (15 min.)
