We investigate the second-stage potential-induced degradation (PID) of n-type front-emitter (n-FE) crystalline silicon (c-Si) photovoltaic (PV) modules. The PID of n-FE c-Si PV modules is known to occur in three stages under negative bias stress. The

This paper presents an overview of an optical instrument for disaster and security monitoring from the geostationary orbit. The described instrument is the payload of the GEOBS (GEOstationary OBServatory) concept, which is the result of an ESA explor

This study addresses the behavior of n-type front-emitter (FE) crystalline-silicon (c-Si) photovoltaic (PV) modules in potential-induced degradation (PID) tests with a long duration of up to 20 days. By PID tests where a negative bias of −1000 V wa

Giardia intestinalis is a parasitic protozoan that causes diarrhea and abdominal pain in humans. Studies of the Giardia genotypes are thought to be important for understanding their infection routes and prevalence. However, few have reported pathogen

We precisely investigate sodium (Na)-induced potential-induced degradation (PID) in n-type front-emitter (n-FE) crystalline silicon (c-Si) photovoltaic (PV) modules, in which open-circuit voltage (V_) and fill factor (FF) deteriorate. Secondary ion m

We sampled twenty-four cooling units for magnetostratigraphic study from a 110 m thick Early Pleistocene volcanic section near Kereyou Lodge in the Main Ethiopian Rift. Seven samples were used from each site for analysis of remanent magnetization usi

It has been unclear how acute hypoxia at moderate altitude affects stroke volume (SV), an index of cardiac function, during exercise. The present study was conducted to reveal whether acute normobaric hypoxia might alter SV during exercise.Nine healt

a b s t r a c t We carried out the first ever paleomagnetic investigations in the area around the Fentale volcanoes, Main Ethiopian Rift. A total of 28 paleomagnetic sites were sampled around the two Fentale (Tinish and Tilik) volcanic centers. Lava

To verify the relationship between oxidative stress and DNA methylation in the young brain, dichlorodiphenyltrichloroethane (DDT) was administered by gavage to male young rats at doses of 0, 0.006, 0.06, 0.6, 6, and 60 mg/kg/day for a period of 4 wee
