A novel electromagnetic-based method is presented for monitoring elemental sulfur deposition within a natural gas-carrying pipeline. The deposited behaves as superstrate layer above sensing microstrip patch antenna that optimally placed on the inner wall of gas Increasing thickness by alters resonance behavior, which can be monitored externally using vector network analyzer. effect uneven or bu...

Cryogen spray cooling (CSC) is used to minimize the risk of epidermal damage during laser dermatologic surgery. During CSC, skin surface is cooled by a short spurt of refrigerant R134a with boiling point of –26.2 C. Since R134a is volatile in open atmospheric conditions, the atomized liquid droplets undergo continuous evaporation as they fly in air, leading to a lost momentum and mass. Therefor...

Soft robotics is a rapidly advancing field that leverages the mechanical properties of flexible materials for applications necessitating safe interaction and exceptional adaptability within environment. This paper focuses on developing pneumatic soft robot bio-inspired in annelids or segmented worms. Segmentation, also called metamerism, increases efficiency body movement by allowing effect mus...

The segmental joints are the weak parts of immersed tunnel structure, and their deformation characteristics closely correlated with waterproof behavior structural safety whole tunnel. In order to study in this paper, E13 pipe section natural foundation an Hong Kong-Zhuhai-Macao Bridge is taken as research object, model test carried out. similarity ratio prototype determined according actual eng...

Particulate matter is a large concern for human health. Fine and ultrafine particulate has been shown to negatively impact health; example, it causes cardiopulmonary diseases. Current regulation targets the size of particles, but composition also impacts toxicity. Indoor sources air pollution pose unique challenges health due potential exposure high concentrations in confined spaces. In this wo...

In order to avoid the influence of end restraint on triaxial stress and strain measurements, this study combines photogrammetry computer technology apply unconsolidated undrained test soil samples. The novel method can establish an intuitive shear band evolution model samples help attain a clear law. On basis conventional test, new needs paste RAD (Ringed Automatically Detected) code points rub...

Recently a joint project has been carried out between the Paul Scherrer Institut, Ecole Polytechnique Federale de Lausanne and swissnuclear, an industrial partner, in order to determine axial void distribution channel installed reflector of zero power research reactor CROCUS, using neutron noise techniques. The main objective present paper is report on validation results against alternative mea...

As a result of COVID-19, many office buildings around the world have downsized their employees, but comfort parameters in building had to be kept. The facilities operation rearranged workstations keep physical distance and placed plexiglass sheets on desks for protection. A series measurements been carried out with workstation set-ups examine fresh air rate occupied zone. effect was also examin...

Heart failure (HF) rates elevate worldwide with the aging population. Miniaturized and wireless implants real-time data transfer capability can alleviate surgical complexities of cardiac pressure monitoring. Despite recent developments mm-size complex circuitries self-powering units, a simple, passive, effective implant design for reading is missing. Here, piezo capsule, cost-effective, miniatu...

The objective of this study was to evaluate the effects different management and land use on soil chemical physical properties as well validate sensitivity leachate. For purpose, effect wastewater discharged soil's taking advantage treatment capacity investigated. In study, natural soils named SA, SG, SK, SU were placed in plexiglass pipes with a length 100 cm diameter 20 fed for 21 days an uni...
