the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...

A porphyrin functionalised with pillar[5]arene and a viologen at its 5- and 15-meso positions assembles in a head-to-tail manner, producing linear supramolecular daisy chains in dichloromethane. At high concentrations, it forms an organogel which has been investigated by electron microscopy and rheological measurements, paving the way for the preparation of other functional supramolecular assem...

[1] The oppositely directed magnetic field in the kronian magnetic tail is expected eventually to reconnect across the current sheet, allowing plasma to escape in an anti-solar direction down the tail. This reconnection process accelerates ions and electrons both toward and away from the planet, allowing the magnetotail to relax to a more dipolar configuration. Previous missions to Saturn shed ...

A new species of the genus Stegelletina is described from caves of Andalucía Oriental (SE Iberian Peninsula). Stegelletina coprophila sp. n. is characterized by its body 386 to 536 mum long in females and 391 and 521 mum in males, lateral field with three incisures, lips bearing four tines, labial probolae 4 to 6 mum long and bifurcate, pharyngeal corpus 1.5 to 2.9 times isthmus length, spermat...

Combined neutral beam injection and fast wave heating at the fourth and fifth cyclotron harmonics accelerate fast ions in the DIII-D tokamak. Measurements with a nine-channel fast-ion D-alpha (FIDA) diagnostic indicate the formation of a fast-ion tail above the injection energy. Tail formation correlates with enhancement of the d–d neutron rate above the value that is expected in the absence of...

The temperature and photoexcitation density dependences of the electron transport dynamics in electrolytefilled mesoporous TiO2 nanoparticle films were investigated by transient photocurrent measurements. The thermal activation energy of the diffusion coefficient of photogenerated electrons ranged from 0.19–0.27 eV, depending on the specific sample studied. The diffusion coefficient also depend...

We report on the optical properties and local bonding configurations of both as-deposited and postannealed hydrogenated amorphous silicon nitride a-SiNx :H thin films grown on crystalline Si substrates with x approximately 1.2±0.1. Ultraviolet optical reflection and infrared IR absorption measurements were applied to characterize the films. A method simply based on optical reflection spectra is...

In the evolutionary transition from an aquatic to a terrestrial environment, early tetrapods faced the challenges of terrestrial locomotion on flowable substrates, such as sand and mud of variable stiffness and incline. The morphology and range of motion of appendages can be revealed in fossils; however, biological and robophysical studies of modern taxa have shown that movement on such substra...

The rectal temperature obtained using a standard electronic thermometer was compared with ear, back skin, tail skin, and sole skin temperatures obtained using an infrared thermometer in B6C3F1 mice. Using both methods, we investigated baseline temperatures, diurnal and 2-week variations in temperatures, and ethanol-induced hypothermia in these body locations. Ear and back temperatures were show...

We have simultaneously imaged the chemically bound head groups and exposed tail groups in bicomponent alkanethiolate self-assembled monolayers on Au{111} with molecular resolution. This has enabled us to resolve the controversy of scanning tunneling microscopy image interpretation and to measure the molecular polar tilt and azimuthal angles. Our local measurements demonstrate that ordered domai...
