Soiling resistant banded earplug

The Journal of the Acoustical Society of America, 1994
A band earplug apparatus is described, of the type which includes a pair of earplug devices (20, 22) lying on the ends of a band (12) that fits halfway about a person's head, which avoids soiling of the earplug devices when the band is laid on a dirty surface. The band is designed so its middle portion (24) rests stably on a horizontal surface (5), and

Heat resistance of fungi from soil

International Journal of Food Microbiology, 1993
The survival of fungi from soil samples has been investigated after exposure to temperatures of 60, 70, 80 and 90 degrees C in Sabouraud agar. The least resistant fungi surviving 60 degrees C for 60 min were the Aspergillus (A.) niger group, Chaetomium spp, Penicillium spp, and Scytalidium lignicola. None of these survived 70 degrees C for 10 min.

Antibiotic resistance in grass and soil

Biochemical Society Transactions, 2019
Abstract Antibiotic resistance is currently one of the greatest threats to human health. The global overuse of antibiotics in human medicine and in agriculture has resulted in the proliferation and dissemination of a multitude of antibiotic resistance genes (ARGs).

Heat-resistant fungi in the soil

International Journal of Food Microbiology, 1992
The occurrence of heat-resistant fungi has been demonstrated in samples of soil from the Slovak Republic. The heat-resistant species isolated were Byssochlamys nivea, Dichotomomyces cejpii, Eupenicillium baarnense, Neosartorya fischeri, Talaromyces avellaneus, Tal. bacillisporus, Tal. emersonii, Tal. flavus, Tal. trachyspermus, Tal.

Heat resistant fungi isolated from soil

International Journal of Food Microbiology, 1994
The Thermal death time values (TDT) were estimated for Dichotomomyces cejpii, Gilmaniella humicola, Talaromyces avellaneus and Talaromyces bacillisporus isolated from soil. TDT values were compared with the TDT values of the known heat-resistant species, Byssochlamys nivea, Neosartorya fischeri and Talaromyces flavus.

Determination of soil parameters to calculate soil resistivity

Russian Electrical Engineering, 2015
This paper is dedicated to the development of techniques allowing for design solutions to be refined on grounding devices. The resistivity is used in the design of grounders in dependence on the soil humidity, temperature, and density. To determine soil humidity at the depth of soil occurrence, two models are used: depending on the season at a depth of

Penetration resistance of lunar soils

Journal of Terramechanics, 1971
Abstract Penetration resistance, in terms of the slope G of the stress penetration curve, has been correlated with density for a basaltic lunar soil simulant. The values were measured with the standard WES 30° cone penetrometer. This lunar soil simulant has been found to possess the same penetration resistance characteristics as the Apollo ...

Erosion resistance of cohesive soils

Journal of Hydraulic Research, 2008
This paper presents experimental results on surface erodibility tests performed with undisturbed and remolded samples of cohesive soils. When subjected to shear stress caused by flowing water, erosion occurs in two distinctive modes: particle erosion and mass erosion.

Measurement of Soil Thermal Resistivity

Journal of the Geotechnical Engineering Division, 1978
Of several available methods for the measurement of the thermal resistivity of soils, the thermal needle method and the Shannon and Wells method are considered most suitable, because of their relative simplicity and the short measurement time required. The thermal needle method is the simpler of the two, and it offers the added advantage that knowledge
