Arrays with polymer-coated acoustic sensors, such as surface acoustic wave (SAW) and surface transverse wave (STW) sensors, have successfully been applied for a variety of gas sensing applications. However, the stability of the sensors' polymer coatings over a longer period of use has hardly been investigated. We used an array of eight STW resonator sensors coated with different polymers. This ...

Herbal combination preparations are widely used in traditional herbal medicine and are even established as modern evidence-based herbal medicinal products. The rationale behind such combinations is often questioned and assessing the contribution of each of the combination partners to overall activity is challenging. STW 5 (Iberogast) is such a combination with confirmed clinical efficacy in fun...

In this study, we used stable isotopes of oxygen (δ18O), deuterium (δD), and dissolved inorganic carbon (δ13CDIC) in combination with temperature, salinity, oxygen, nutrient concentrations to characterize the coastal (71°–78°W) an oceanic (82°–98°W) water masses (SAAW—Subantarctic Surface Water; STW—Subtropical ESSW—Equatorial Subsurface water; AAIW—Antarctic Intermediate PDW—Pacific Deep Water...

Increasing numbers of widely used industrial, agricultural, and natural chemicals are known to elicit endocrine-disrupting effects in a wide range of vertebrate and invertebrate species. The objective of this study was to determine whether the sexual development of the freshwater crustacean Gammarus pulex (L.) was affected below sewage treatment works (STW) previously known to contain endocrine...

Many applications of search theory in monetary economics use the Shi-TrejosWright model, hereafter STW, while applications in finance use Duffie-GârleanuPederson, hereafter DGP. These approaches have much in common, and both claim to be about liquidity, but the models also differ in a fundamental way: in STW agents use assets as payment instruments when trading goods; in DGP there are no gains ...

[Purpose] The purpose of this study was to clarify the effects of directional change on postural adjustments during the sit-to-walk (STW) task. [Subjects] Fifteen healthy young men participated in this study. [Methods] Subjects were required to stand up from a chair and walk toward a target. The first step was limited to the right limb only. Three conditions of target direction (straight, ipsil...

Vancomycin susceptibility of methicillin-resistant Staphylococcus aureus has been changed over time and its average minimum inhibitory concentration increased from 1.5 to 1.75 mg/L. A recently published guideline by the American Society of Health Pharmacist recommended a daily dose of 15-20 mg/kg every 8 to 12 hours of vancomycin to achieve a trough concentration between 15-20 mg/L for treatmen...

Isolation piles are widely used to control the influence of shield tunnelling on adjacent buildings as an effective protective measure. However, restraint effect isolation pile surface settlement trough is rarely explored from internal mechanism. Firstly, mechanism investigated pile-soil-tunnel interaction Secondly, based Melan solution and Loganathan formula, analytical under derived. Thirdly,...

Batiaghata Upazila, Khulna District in south-west coastal region of Bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (STW) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. Electrical Conductivity (E...
