We have been developing a free-electron laser (FEL) in the far-infrared or terahertz (THz) region for higher intensity and stability, using the L-band (1.3 GHz) electron linear accelerator (linac) at the Institute of Scientific and Industrial Research (ISIR), Osaka University. The FEL was progressively upgraded, and the maximum energy of micropulses, which form an FEL macropluse of a duration of some microseconds, reached 260 μJ at a wavelength around 65 μm or a frequency around 4.6 THz, which is an order of magnitude higher than micropulse energies obtained in other FELs in this wavelength or frequency range. Experiments have begun using high-intensity narrow-band terahertz radiation from the FEL. This paper summarized the progress of the FEL and its application experiments.

The present study reaffirmed that single-use of disorder-orientated functional foods may not be effective in resolving certain muscle- and orientation-relevant health problems. A male diabetic patient P on a functional food A (a product for blood pressure control) intake for more than 10 yr suffered from certain physical symptoms (PSs) such as forearm Grip-holding (FGH) muscular strength (PS-1), hindlimb joints (HJs) discomfort (PS-2), physical balance or orientation on one-legged standing (PS-3), and urination flow onset-latency and duration of complete emptying (PS-4) as well as poor metabolic indexes such as high levels of total cholesterols (T-Cho), low-density lipoprotein-cholesterols (LDL-C), triglycerides (TG), and HbA1C. When intake of A was complemented with daily product B, intake all PSs improved in a time-dependent manner; with different PS improvements requiring different intake duration: shorter intake duration for PS-1 (3-wk intake and thereafter), and longer intake durations for other PSs (at least more than 3-month intake). Additionally, high levels of T-Cho and relevant indexes were also improved over time with different intake durations, although the blood sugar levels (HbA1c) were unaffected. T-Cho (3-month intake), LDL-C (3-month intake), TG (after 6-month intake) were restored after different intake durations; however, blood sugar levels (HbA1c) were unaffected despite mulberry leaf extract having been documented to reduce blood sugar levels. Improvements of PSs and metabolic indexes were probably due to complementary effects of B whose effects in combination with A improved metabolic activity, nutritional, blood circulation and neurological effects and may have contributed to the favorable outcomes in this study.

Review of Research on Covid-19

Review of Research on Covid-19


The University of Queensland, St. Lucia, Queensland 4072,   Australia (jandjdej@bigpond.net.au)

A number of approaches to alleviate the Covid-19 pandemic have been discussed as well as longer term solutions. It seems possible that, when the pandemic has run its course, Covid-19 will continue at a low level in the community and be controlled by a vaccine and selective drugs developed as a consequence of the pandemic. How rapidly the properties of the virus may change as a result of mutations remains to be seen. Changes may lead to weakening of vaccine efficacy, development of drug resistance and/or to a strengthening or weakening of the virus' infectivity. The Covid-19 pandemic has highlighted once again the possibility that future viruses may cross the animal human barrier with devastating consequences. Such events are rendered more likely by increases in world population and destruction of wild animal habitat.
