Hydraulic conductivity and compressibility characteristics of bentonite enriched soils as a barrier material for landfills

An experimental program was undertaken for the index and engineering properties (compaction, hydraulic conductivity and consolidation) of various mix proportions of sand, silt and coal ash with bentonite as an admixture to act as a barrier material for landfills. Thirty-four mixes were tested in all with different categories of mixes comprising of bentonite–sand, ...

Experimental studies on impedance based fault location for long transmission lines

In long transmission lines, the charging current caused by the shunt capacitance decreases the accuracy in impedance based fault location. To improve the accuracy of fault location, this paper presents a novel scheme, where two Digital Fault Recorders (DFRs) are installed in a line. They can send the transient data of the faults to the both ends of a line. To estimate the distance ...

Instituut voor publieke waarden

Yvonne is diep ongelukkig. Weer een afwijzing. Laatst probeerde ze het voor de vierde keer. Telkens was het spannend. Telkens moest ze een drempel over. Maar ze ging toch naar de sociale dienst. Want ze had die uitkering echt nodig. Iedere keer maakte ze braaf aantekeningen tijdens de workshop. Haar c.v. op orde brengen, solliciteren, en de opdracht invullen. Ze begreep het ...

‘Je kinderen beschermen tegen beslagleggingen’

Successful hepatectomy for hepatic abscess with chronic granulomatous disease: a case report

Background Chronic granulomatous disease (CGD), a rare inherited disorder, is characterized by impaired ability of phagocytic cells to kill certain bacteria and fungi. Although liver abscess is a common manifestation of CGD, its optimal management in these patients is unknown. Here, we present a case of successful hepatectomy for hepatic abscess in a patient with CGD. Case ...

Degradation of bromophenol blue molecule during argon plasma jet irradiation

The aim of this paper is to study degradation of a bromophenol blue molecule (C19H10Br4O5S) using direct irradiation of cold atmospheric argon plasma jet. The pH of the bromophenol blue solution has been measured as well as its absorbance spectra and conductivity before and after the irradiation of non-thermal plasma jet in various time durations. The results indicated that the ...

Non-isothermal stability by linear heating: a fast method for preformulation stability screening of drugs at the discovery and development interface

The non-isothermal method for prediction of chemical stability of pharmaceuticals has been discussed in the literature for almost half a century but it has not yet been systematically evaluated. The purpose of this study was to carry out a comprehensive experimental evaluation of the non-isothermal method against the conventional isothermal method for a fast preformulation ...

Effects of astaxanthin on antioxidant capacity of golden pompano (Trachinotus ovatus) in vivo and in vitro

The objective of this research was to study the effect of astaxanthin (AST) on growth performance and antioxidant capacity in golden pompano (Trachinotus ovatus) both in vivo and in vitro. In the in vivo study, two diets were formulated with or without astaxanthin supplementation (D1 and D2; 0 and 200 mg/kg) to feed fish for 6 weeks. In the in vitro study, cells from hepatopancreas ...

Compressive strength behavior of concrete by partial replacement of regular brick with over-burnt brick aggregate

Numerous kinds of coarse aggregates are being used around the world, and most of these coarse aggregates are naturally originated. Due to the gradual diminution of natural resources, modern society is facing a challenge in concrete work which demands a huge amount of coarse aggregate. In Bangladesh, handful brick fields around the country made brick aggregate available as well as ...

Conditions for Employee Learning and Innovation – Interweaving Competence Development Activities Provided by a Workplace Development Programme with Everyday Work Activities in SMEs

The aim of this article is to investigate how the formal competence development activities provided by the Production Leap, a workplace development programme (WPDP), were interwoven with everyday work activities and to identify the conditions that enabled learning and employee-driven innovation that contributed to production improvement, in small and medium-sized enterprises (SMEs) ...

Allometry varies among related families of Norway spruce

Key message Slopes and intercepts of allometric equations for organs’ biomass varied among half-sib families of Norway spruce and between age categories in a family-dependent manner. Genetic variation should be accounted for when applying allometric analysis to mixtures of genetic groups. Context Genetic variation in relationships among plant biomass components was rarely addressed ...

Tests of the Stability of Chinese RhFe Resistance Thermometers at Low Temperatures

Rhodium–iron resistance thermometers are recommended as precise thermometers at temperatures below 25 K. The thermometers were developed at the National Physical Laboratory and produced by H. Tinsley and Co Ltd almost 50 years ago. Later, they were made by other companies and institutes as well, but despite this, the availability of the thermometers decreased and a new source of ...
