Impact of spectral features of common LED lighting systems on TM-30 color indices.

We examine the difference between the newly developed IES TM-30 color indices and some of the most common previously established color indices for LED systems which are used for lighting purposes, focusing on the influence of realistic spectral variations among different system designs and manufacturing runs. We find a significantly stronger influence of the employed blue InGaN wavelength on TM-30 R and R than on CRI R and FCI. In addition, for the established combination of green converted InGaN chips with red InGaAlP chips, we observe large differences in the effect of the wavelength of the red emission of InGaAlP chips on R and R.

Remote detection of rhizomania in sugar beets.

ABSTRACT As a prelude to remote sensing of rhizomania, hyper-spectral leaf reflectance and multi-spectral canopy reflectance were used to study the physiological differences between healthy sugar beets and beets infested with Beet necrotic yellow vein virus. This study was conducted over time in the presence of declining nitrogen levels. Total leaf nitrogen was significantly lower in symptomatic beets than in healthy beets.

Characteristics of Beet Soilborne Mosaic Virus, a Furo-like Virus Infecting Sugar Beet.

Beet soilborne mosaic virus (BSBMV) is a rigid rod-shaped virus transmitted by Polymyxa betae. Particles were 19 nm wide and ranged from 50 to over 400 nm, but no consistent modal lengths could be determined. Nucleic acids extracted from virions were polyadenylated and typically separated into three or four discrete bands of variable size by agarose-formaldehyde gel electrophoresis.

[Karl Sudhoff's contribution and position to history of stomatology].

Among the few German medicohistorians of the 19th and the early 20th century contributing essentially to the formation of history of stomatology and to its methodologic and cognitive progress. Karl Sudhoff was the most eminent one. He was already very early aware of the full responsibility for stomatology--transferred with the stomatologie examination regulations in 1909--as a task relevant also for his special branch.

[Georg Ilberg (1862-1942). His life and medical-humanistic legacy].

Georg Ilberg, who is almost forgotten nowadays, was a scholar of Kraepelin and Ganser. From 1910 to 1928 he was director of the Landes-Heil- und Pflegeanstalt (country mental hospital) for mental patients Sonnenstein at Pirna. He was active in the scientific-literary field to a great age and worked as editor of the Allgemeine Zeitschrift für Psychiatrie from 1924 to 1934.

[Possibilities of rapid diagnosis in meningitis].

The paper reviews rapid diagnosis methods for meningitis, covering currently proved immunological and physiochemical procedures, supplemented by reference to clinical biochemical tests.

[Trigeminal involvement following preventive influenza vaccination].

Neuralgia-like complaints occurred in the region served by the ramus ophthalmicus et maxillaris nervi trigemini dexter of a woman aged 48 years two days after she had been inocculated with an inactivated influenza-A adsorbate complete vaccine (A/Bangkok/1/79 (H3-N2)); (A/Brazil/11/78 (H1-N1)). The clinical findings are explained, and the possibility of a connection between the symptomatology and a previous inocculation is discussed.
