Design, Realization, and Test of Ultraviolet-C LED Arrays Suitable for Long-Lasting Irradiation of Biological Samples

open access: yesMachines, 2023
We present the electrical and optical design, assembling, and thorough experimental characterization of two compact arrays of short-wavelength ultraviolet (UV-C) light-emitting diodes (LEDs) suitable for near-field irradiation.

Point of Care Diagnosis of Multiple Schistosome Parasites: Species-specific DNA Detection in Urine by Loop-mediated Isothermal Amplification (LAMP) [PDF]

open access: yes, 2017
Schistosomes are easily transmitted and high chance of repeat infection, so if control strategies based on targeted mass drug administration (MDA) are to succeed it is essential to have a test that is sensitive, accurate and simple to use.

A dynamic conductance model of fluorescent lamp for electronic ballast design simulation [PDF]

open access: yes, 2005
A Spice-compatible dynamic conductance model of a fluorescent lamp for use in electronic ballast simulation is presented. The time-dependent conductance of the fluorescent lamp is derived from a plasma ionization balance equation that uses simplified ...

High frequency electronic ballast provides line frequency lamp current [PDF]

open access: yes, 2001
Most electronic ballasts for fluorescent lamps provide a sinusoidal lamp current at the switching frequency. The high-frequency current flowing through the lamp can generate significant radiated noise, which is unacceptable in noise-sensitive ...

A novel vacuum ultra violet lamp for metastable rare gas experiments [PDF]

open access: yes, 2011
We report on a new design of a vacuum ultra violet (VUV) lamp for direct optical excitation of high laying atomic states e.g. for excitation of metastable rare gas atoms. The lamp can be directly mounted to ultra high vacuum vessels (p

Arrested norm development: The failure of legislative-judicial dialogue in the WTO

open access: yesLeiden Journal of International Law
The WTO’s 30-year history has been marked by a well-known imbalance: while WTO Members have largely failed to negotiate new legal rules, the WTO’s dispute settlement system has been extraordinarily active.

Real-time kinetics and high-resolution melt curves in single-molecule digital LAMP to differentiate and study specific and non-specific amplification [PDF]

open access: yes, 2020
Isothermal amplification assays, such as loop-mediated isothermal amplification (LAMP), show great utility for the development of rapid diagnostics for infectious diseases because they have high sensitivity, pathogen-specificity and potential for ...
