Sunlight-mediated inactivation of health-relevant microorganisms in water: A review of mechanisms and modeling approaches

Tamar Kohn, Yang Liu, Krista Rule Wigginton

Health-relevant microorganisms present in natural surface waters and engineered treatment systems that are exposed to sunlight can be inactivated by a complex set of interacting mechanisms. The net impact of sunlight depends on the solar spectral irradianc ...

The formation of the Milky Way halo and its dwarf satellites; a NLTE-1D abundance analysis

Pascale Jablonka, Pierre North

We present a homogeneous set of accurate atmospheric parameters for a complete sample of very and extremely metal-poor stars in the dwarf spheroidal galaxies (dSphs) Sculptor, Ursa Minor, Sextans, Fornax, Botes I, Ursa Major II, and Leo IV. We also deliver ...

Low-profile multi-function antenna system for small satellites

Juan Ramon Mosig, Frédéric Bongard, Tomislav Debogovic, Ferdinando Tiezzi, Pedro Robustillo Bayon, Nevena Saponjic

A low-profile multi-function antenna system suitable for small satellites is presented in this paper. The antenna system operates at UHF frequency band (400 MHz) and comprises eight miniaturised radiating elements (REs) based on a folded planar inverted-F ...

Tunable radiator for small satellite application

Jean-Daniel Landis, Frédéric Bongard, Tomislav Debogovic, Pedro Robustillo Bayon, Nevena Saponjic, Mikaël Krummen

A tunable radiator for space application has been developed to meet stringent requirements in terms of electrical and environmental specifications but also low mass, simple manufacturing and low cost. The element is based on the folded PIFA antenna, with s ...

Therapeutic Proteins Engineered for Super-Affinity to the Extracellular Matrix in Regenerative Medicine

Priscilla Suhasna Maithili Briquez

Regenerative medicine aims to repair body tissues when natural mechanisms fail. Growth factors (GFs) are essential proteins that promote tissue regeneration upon injury, and as such, are very promising therapeutic drugs in regenerative medicine. Due to the ...

Incorporation of advanced aerosol activation treatments into CESM/CAM5: Model evaluation and impacts on aerosol indirect effects

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

One of the greatest sources of uncertainty in the science of anthropogenic climate change is from aerosol-cloud interactions. The activation of aerosols into cloud droplets is a direct microphysical linkage between aerosols and clouds; parameterizations of ...

GNSS to reach the Moon

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Jia Tian, Yanguang Wang

Reaching the Moon poses very strict requirements in terms of performance, flexibility and cost for all the spacecraft subsystems. These requirements become more stringent if the mission is designed to be accomplished using a small satellite. The navigation ...

GNSS PERFORMANCES FOR MEO, GEO AND HEO

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Global Navigation Satellite Systems (GNSSs) such as GPS, GLONASS, and the future Galileo and BeiDou, have demonstrated to be a valid and efficient system for various space applications in Low Earth Orbit (LEO), such as spacecraft orbit and attitude determi ...
