Abstract The development of the infrared (IR) absorption band at 1640 cm −1 (δH 2 O) is employed to monitor the gain in molecular water of progressively mortar-ground kaolinite. The planimetred area of this band shows a linear correlation with weight loss at 105°C (free moisture) between 2 and 18 h grinding, indicatin…
A mathematical model based on four modes of operation is developed to predict the tensile response of a hybrid circular braid encompassing an elastic core. Model inputs include parameters characterizing the initial geometric configuration and ma terial properties of the hybrid. Output parameters are forces, strains, m…

Both anisotropic ablation and thin film formation of polytetrafluoroethylene (PTFE) were successfully demonstrated using synchrotron radiation (SR) irradiation of PTFE, that is, the SR ablation process. Anisotropic ablation by the SR irradiation was performed at an extremely high rate of 3500 µm/min at a PTFE target t…
A phase transition at ca 228K in cadmium trithiophosphate, CdPS 3 , has been characterized by means of single-crystal X-ray diffraction. The low-temperature phase crystallizes in trigonal symmetry [a = 6.224(3), c = 19.49 (1) A, V = 654(1) A 3 and Z = 6]. The structure determination was conducted from 679 reflections…
Strong-segregation theory (SST)l models microphase-separated block copolymer melts in terms of polymeric brushes. This approach has provided intuitive and well-accepted explanations for phase behavior far below the order-disorder transition. According to the model, AB diblock copolymers self-assemble with their juncti…

An air‐metal hydride battery (32 Ah) using a noble metal‐free air electrode (300 cm 2 ) was constructed and tested. The battery was charged with a third nickel mesh electrode and discharged using oxygen, with discharge voltages of 0.87 V at 3 A and 0.58 V at 30 A. The peak power was 25 W (83 mW/cm 2 ) with oxygen and…
This is a study of visual contrast sensitivity in a series of subjects with previously diagnosed occupational organic-solvent-induced chronic toxic encephalopathy. Contrast sensitivity was measured for 16 subjects using the Vistech VCTS 6500 chart. The results were compared with age-stratified normal data. Six of the…

A mathematical model for the discharge of a metal‐hydride electrode was developed. The model was used to study the effect of various parameters on predicted discharge curves. The simulations obtained using the model show the expected decrease of charge utilization as the rate of discharge is increased. Increasing the…
The influence of zirconium and hafnium additions in substitution to titanium, is investigated on TiNi shape memory alloy. Microstructural and thermomechanical studies are conducted on an arc-melted Ti38Ni50Hf12 alloy. Results are compared with those of an equiatomic TiNi.
The isocitrate dehydrogenases from the extremely halophilic Archaeon, Haloferax volcanii, and from the hyperthermophilic Archaeon, Sulfolobus solfataricus, have been purified to electrophoretic homogeneity. The purified enzymes have been characterised with respect to their cofactor specificities, subunit compositions…
Tryptophan synthase, an alpha 2 beta 2 tetrameric complex, is a classic example of an enzyme that is thought to "channel" a metabolic intermediate (indole) from the active site of the alpha subunit to the active site of the beta subunit. The solution of the three-dimensional structure of the enzyme from Salmonella typ…
