A mercury-film electrode with iridium as the substrate has been developed. Various metals were considered as potential electrode substrates, but only iridium was found to possess the desirable properties as a Hg-film substrate. After testing several pretreatment procedures the recommendation is to polish with 1 pm diamond, rinse with chromic acid and cathodize at -2.0 V vs. SCE. Different depos...

Real-time radiography systems employing an image intensifier tube have poor resolution (2 to 4Ip/mm) compared to their film-based counterparts (10 to 20 lp/mm). Phosphor bloom, especially in the output conversion phosphor [1], is the principle cause of reduced resolution. Other systems achieve higher resolution but at the expense of additional hardware complexity [2] or use of expensive materia...

In order to develop a software that aims at helping reducing the electrical energy consumption in the domestic sector of the European Union, it becomes necessary to model the electrical energy consumption of the main home appliances as a function of their features such as energy class, capacity and operating set-ups. This paper focuses on the modeling of electrical energy consumption of the was...

We developed a biphasic method for recovery and enumeration of campylobacters. The biphasic system was composed of 96-well microtiter plates containing Campy–Line agar prepared 2¥ for all ingredients except for 1¥ agar (0.1 mL per well). Samples were prepared in either twofold or fivefold dilution series across separate 96-well plates and directly transferred (0.1 mL) to the agar-containing mic...

The State of Florida has a radon standard for new construction. This study was conducted to evaluate the effectiveness of two slab types (monolithic and slab-in-stem wall) in retarding radon entry in new houses built in accordance with the proposed standard over high radon potential soils. Fourteen houses were monitored during their construction on sites whose soil gas radon concentrations were...

The test definition language TTCN-3 is currently under standardization by ETSI/ITU-T. Its intended field of application is testing and performance measurement of communication hardand software. TTCN-3 does include mechanisms for specifying remote hardware access and for distributed execution of testing code components. But for running compiled TTCN-3 code distributed onto distinct nodes of diff...

The borazocine (ClB=NCMe3)4 crystallizes in the monoclinic system, space groupC2/c with Z = 6, i. e. there are two independent molecules in the unit cell. The first molecule has no crystallographic symmetry, while the second molecule is characterized by a twofold axis which generates the (ClB= NCMe3)4 molecule from the fragment (ClB=NCMe3)2. The molecules are tub-shaped showing alternating long...

The article presents a construction and testing of a new family of magnetorheological dampers. The work began with testing currently used solutions, which exist inter alia in vibratory machines for example in washing machines. Basis on this job required damping parameters were obtained and then these parameters were used as input data in new devices designing process. A distinguishing feature o...
