In the late thirteenth century, Theodoric of Freiberg, a Dominican monk, theologian, and physicist, performed a simple experiment: with his back to the sun, he held a spherical bottle filled with water in the sunlight. By following the trajectory of the refracted and reflected light and having the bottle play the same role as a single water drop, he gave a scientific explanation of rainbows, in...
From 1978 to 1987 107 cases of chemical burns were treated. The patients were mainly young and middle age people (83.08%), with mean burned areas 17.8%. The majority of involved parts were low extremities. 57.44% of burned eyes became blind. Mean days in hospital were 43 days. Cure rate was 98.13% and death rate 1.87%. We emphasized that burned wounds must instantly be washed down with water, i...

Advancements in semiconductor technology have led to a steady increase in the unity power gain frequency (fmax) of silicon transistors, both in CMOS and SiGe BiCMOS technologies. This, in turn, enables realization of complex monolithic silicon integrated circuits operating at the millimeter-wave (mm-wave) frequency range (typically defined as 30–300 GHz). Prime target applications of silicon mm...
One hundred seven patients were retrospectively studied from 1992 to 2002 with diabetic neuropathy that underwent peripheral nerve biopsy. Nerve biopsy revealed the underlying histopathology, including cell and humoral-mediated immunological lesions in the majority of patients. When combined with clinical and laboratory studies, nerve biopsy has the potential to assist in the selection of patie...
Motivation has been traditionally defined as energy (e.g., running speed) and direction (e.g., toward food), and the determinants of motivation as need (e.g., for food), expectation (e.g., cognitive map of the maze), and incentive value (e.g., quality of the food). When motivation toward attaining a desired future meets resistance or conflict, self-regulation becomes relevant. The use of effect...
Indications for colposcopy Ideally all women with abnormal cervical cytology and/or positive hrHPV should undergo colposcopic assessment to identify those with and those without any clinically visible lesions. This allows clinical verification of the cervical cytology and hrHPV report. In those with an atypical lesion, the colposcope can aid diagnosis and management as appropriate. In those wom...
The neutron-rich isotopes of cadmium up to the N=82 shell closure have been investigated by high-resolution laser spectroscopy. Deep-uv excitation at 214.5 nm and radioactive-beam bunching provided the required experimental sensitivity. Long-lived isomers are observed in (127)Cd and (129)Cd for the first time. One essential feature of the spherical shell model is unambiguously confirmed by a li...
