Relative Sensitivity of Several Plants to Diphenamid

Weed Science, 1971
The concentration of N,N-dimethyl-2,2-diphenylacetamide (diphenamid) required to cause 50% growth inhibition (I50) of the shoots or roots in soil, or the roots in a bioassay, was determined for several species. of the plants tested, grasses were the most sensitive, while Solanaceae were among the most tolerant to diphenamid.

Approximate energy gaps, dissimilar relative thermal sensitivities

Sensors and Actuators B: Chemical, 2018
Abstract In this field of luminescence ratiometric thermometry, it is long believed that those thermally coupled energy levels (TCELs) spaced by the approximate gaps own similar relative sensitivities (Sr), when the expression Sr = ΔE/kT2 is taken into consideration, where ΔE is the gap between TCELs, k the Boltzmann constant, and T the absolute ...

Sensitive Pyrometer with High Relative Reproducibility

Review of Scientific Instruments, 1962
The accuracy of measurement of temperature and particularly temperature distribution in current heated wires can be considerably improved by using semiconducting light-sensitive resistors as a pyrometer. They feature almost exponential dependence of their resistivity on temperature of the hot wire and insensitivity against changes in ambient ...

Relative Sensitivity of Several Plants to Dinoseb

Weed Science, 1971
The I50values obtained with preemergence applications of 2-sec-butyl-4,6-dinitrophenol (dinoseb) for shoot and root growth in soil, or root growth in a bioassay were determined for 68 plant varieties representing 66 species. The I50values in soil indicate a difference of more than 240 fold between the most sensitive species, shepherdspurse (Capsella ...

Relative Sensitivity of Pine Species to Ozone

Arboriculture & Urban Forestry, 1982
Seedlings of Pinus banksiana, P. parviflora, P. ponderosa, and P. sylvestris showed the most foliar injury to ozone fumigation at 20 and 30 pphm during an 8 hr/day, 70 day period. Pinus aristata and P. strobus showed the least injury, and were most tolerant. P. nigra, P. strobiformis, and P. thunbergii were moderately tolerant but sustained some injury.

Mutagen-sensitive mutants in drosophila: Relative MMS sensitivity and maternal effects

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1978
Abstract The sensitivity of larval populations of Drosophila melanogaster to the lethal action of methyl methanesulfonate (MMS) was determined. Wild-type strains were compared with strains carrying X-linked mutations that increase mutagen sensitivity.

Sensitive Method for Measuring the Relative Abrasiveness of Dentifrices

Journal of Dental Research, 1968
A procedure involving the use of a tritiumlabeled acrylic strip was developed for the rapid, accurate, and reproducible evaluation of the abrasiveness of dentifrices. Comparisons were made of dentifrices widely sold in the United Kingdom (including some marketed specifically for denture cleaning) and a standard paste.

The relative sensitivities of autoradiographic emulsions to negative chemography

Journal of Microscopy, 1988
SUMMARYNuclear emulsions from Ilford, Kodak (U.K.), Eastman Kodak and Sakura have been exposed under comparable conditions to sections known to cause negative chemography. Kodak AR‐10 and Eastman Kodak NTB‐2 and NTB‐3 emulsions did not show negative chemography. Ilford K5, K2 and L4 and Sakura NR‐M2 showed varying degrees of chemography.

CONCEPTUAL RELATIVITY AND SPEAKING-SENSITIVE SEMANTICS

2008
The main goal of this paper will be to analyze the relationship between the phenomenon of conceptual relativity and the speaking-sensitive semantics. My paper will be divided into three parts. In the first part I will present Putnam’s the phenomenon of conceptual relativity, in the second part I will exhibit the main ideas that characterize the ...

Relative sensitivity of some selected aquatic organisms to phenol

Bulletin of Environmental Contamination and Toxicology, 1995
Although the possibility of adverse effects of materials on organisms was recognized earlier, not until the 1940s or 1950s short-term acute tests with fishes were being studied. The fishes have become the most popular test organism because the effects of toxic substances in streams have been most evident on the fishes.
