Aboriginal Australian acrylic paintings have long been considered representations of mythologically invested landscape. This understanding has been made problematic by recent writings on ‘dwelling’. As common usage of the term ‘landscape’ seems to prioritize vision, to suggest that the acrylic paintings are landscapes only strengthens the suspicion that they are artifacts of displacement or dis...

In the title 1/2 adduct, C(10)H(8)N(2)·2C(7)H(6)O(2)S, the dihedral angle between the pyridine rings is 18.41 (11)°. In the thio-phene-acrylic acid mol-ecules, the dihedral angles between the respective thio-phene and acrylic acid units are 5.52 (17)° and 23.92 (9)°. In the crystal, the components are linked via O-H⋯N hydrogen-bonding inter-actions, forming units of two 3-thio-phene-acrylic aci...

Background: The aim of this work was to study the output factors for Linac using different ionization chambers and build up caps. Materials and Methods: Output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 MV photon beams from a Varian Clinac 2100C accelerator were measured. The measurements in air were performed using Com...

1. The ionic dependence of action potentials evoked in giant smooth muscle fibres isolated by enzymatic digestion from the body wall of the marine invertebrate Beroe ovata (Ctenophora) has been investigated using conventional electrophysiological techniques. 2. Differences were observed in the two fibre types studied. The resting membrane potential was —60 ± 135 mV (JV = 25) in longitudinal mus...

this study aimed to evaluate the cellular toxicity of two newly-released acrylic resins (futura gen and gc reline hard) in comparison with the conventional heat-cure resin (meliodent).sample discs from each acrylic resin were placed in 24-well culture plates along with l929 mouse fibroblast cell line. a mixture of the rpmi 1640 medium, antibiotics and 10% fbs was added to the plates and the spe...

The goal of the study, is to specify mechanical properties of epoxy and acrylic-based adhesives commonly used for bonding of metal connections. For this reason, the bulk specimens, manufactured from Devcon A and Akfix-E300 as epoxy material, Erde GTR and Erde GTS as acrylic based adhesive material, were cast in accordance with the test standards. The mechanical properties of the specimens obtai...

white, red and superficial. In common with teleost fish, the different types are well segregated in the body. The white fibres make up the bulk of the body, the red fibres form a band along the lateral edge of the body and the single layer of superficial fibres is confined to a narrow band between the skin and the red fibres. Each fibre type has a distinct histological and biochemical profile w...

Introduction: The purpose of this study was to compare dimensional changes of two types of auto polymerizing acrylic resin patterns (APARPs) in three different storing environments. Methods: 60 acrylic post and core patterns were made of two types of Duralay acrylic resins (Aria dent, Iran and Reliance, Dental Mfg. Co, USA) using a canine model. Then coronal, apical diameter and coronoapical le...

An efficient technology for preparing lotus fibres under microwave irradiation was developed. The lotus fibres were characterized by scanning electron microscopy, Fourier transform infrared spectrometry, X-ray diffraction and thermogravimetry. Lotus fibres prepared are a kind of hollow fibres which are composed of a superfine fibre and an external shell. The effect of the treatment time with hy...
