Reported cases of allergic contact dermatitis caused by methylenediphenyl diisocyanate (MDI) have increased and thereby increased the need for adequate skin protection. Current standardized permeation and penetration test methods give information about efficacy of protective materials against individual components of the polyurethane systems. They do not give information of what kind of clothin...

OBJECTIVE Several methods for evaluating semen quality have been developed in addition to traditional semen analysis. Most of these methods are very complex and require expensive technical equipment as well as special knowledge to be performed. The aim of this study was to establish an easy and cost-effective sperm penetration test for bovine semen using artificial media. Additionally a standar...

A hollow cylinder apparatus was used to investigate the inherent anisotropy and membrane penetration of Leighton Buzzard sand test-specimens. The degree of inherent anisotropy was found to be independent of the mean effective stress but dependent on the initial relative density of the test-specimen. In the vertical-tohorizontal directions, the degree of inherent anisotropy decreases with increa...

The seabed Cone Penetration Test (CPT) system is a common method for investigating offshore soil. This paper focuses on new subsea CPT assessing physical and mechanical properties of marine sediments. enables automatic docking dismantling the probe rods underwater. constant-rate penetration mechanism basis core component CPT, allowing rod cone to penetrate seafloor sediment. Double hydraulic cy...

Due to the introduction of Eurocode 8, the structural design for seismic and dynamic effects has become more significant in Hungary. This has emphasized the need for more effort to describe the behavior of structures under these conditions. Soil conditions have a significant effect on the response of structures by modifying the stiffness and damping of the soil-structural system and by modifyin...

Assessing network security is a complex and difficult task. Attack graphs have been proposed as a tool to help network administrators understand the potential weaknesses of their networks. However, a problem has not yet been addressed by previous work on this subject; namely, how to actually execute and validate the attack paths resulting from the analysis of the attack graph. In this paper we ...

The penetration result obtained on a filter test stand depends on several factors. Two of these are challenge aerosol size distribution and the particle detector used to measure the particle size and concentration. Some filter testers employ a monodisperse aerosol challenge while others use a polydisperse challenge. Some particle detectors are based on particle counting while others are based o...

Recently, barrier-coverage in wireless sensor networks is a critical issue because it can be used for various applications (e.g., intrusion detection and border protection). Many existing works for barrier-coverage assume that an intruder penetrates through two opposite sides such as from top to bottom or from bottom to top and focus on constructing barriers to detect those penetrations. Howeve...

Knowledge of acoustic arrival angle can be useful for studying penetration mechanisms and for estimating sediment sound speed dispersion. The arrival angle of the acoustic field penetrating the water-sediment interface, however, is difficult to measure using sparsely distributed pressure sensors. The arrival angle, as well as amplitude information, can be unambiguously obtained by measuring par...
