Transmission Loss (TL) of a glass cylinder tube containing a fluid is studied experimentally. This test specimen represents a typical double layer panel including a fluid. The tests are carried out by using a modified four-microphone standing-wave (impedance) tube for specimens with different lengths, 15 and 30 mm. Each cylinder tube is tested filled with one of the fluids at a time. The fluids...

The Coupling Loss Factors (CLF) to describe the vibration transmission at junctions in context of Statistical Energy Analysis (SEA) are determined. Out-of-plane energy (bending waves) and in-plane (treating transverse shear waves quasi longitudinal as a single subsystem) well their interactions considered. CLF values obtained from inverse SEA problem where energies input powers computed numeric...

Background: Similar to the thermoluminescence (TL) spectra, the optical parameters variations can also be used in TL crystals for dosimetry purposes. These optical parameters can include absorption, transmission and reflection coefficients. Materials and Methods: Single crystals of KBr and KCl which have been used in this research were grown from laboratory grade extra pure precursor p...

Typhoon induced sediment warming has been proven important to coastal sound-field change in this study. It was observed that the temperature of the bottom waters off the coast of Qingdao increased by 5 °C after the passage of typhoon Damrey in 2012. Sediment warming due to bottom-water temperature increase was calculated and the change in sediment sound speed was estimated. Transmission loss (T...

A thymus-leukemia (TL)-specific probe, pTL1, has been generated from a TL-coding gene of BALB/c mice. Multiple species of TL mRNA were detected in TL+ cells by Northern blot analysis with pTL1, and different Tla haplotypes could be distinguished on the basis of characteristic patterns of TL mRNA. No TL-related message was found in normal or leukemic TL- cells, including thymocytes from Tlab mic...

in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...

In Drosophila pseudoobscura, the amylase (Amy) multigene family is contained within a series of inversions, or gene arrangements, on the third chromosome. The Standard (ST), Santa Cruz (SC), and Tree Line (TL) inversions are central to the phylogeny of arrangements, and have clusters of other arrangements derived from them. The gene arrangements belonging to each of these three clusters have a ...

A novel structure of dual-composite right/lefthanded transmission line (D-CRLH TL) is proposed and analyzed in this paper. The simulated results show that there is a stopband between the first right-handed passband and the left-handed passband of the proposed D-CRLH TL. This stopband characteristic is applied to improve the electromagnetic performances of low-pass filter (LPF). A planar compact...

The ontogeny of hearing in fishes has become a major interest among bioacoustics researchers studying fish behavior and sensory ecology. Most fish begin to detect acoustic stimuli during the larval stage which can be important for navigation, predator avoidance and settlement, however relatively little is known about the hearing capabilities of larval fishes. We characterized the acoustically e...

Background. Endemic areas of tegumentary leishmaniasis (TL) in Salta, Argentina, present some overlap zones with the geographical distribution of Chagas disease, with mixed infection cases being often detected. Objectives. The purpose of this study was to determine the magnitude of Leishmania sp. infection and potential associated risk factors, the serologic prevalence of T. cruzi, and the pres...
