Education and expectations for patients with viral upper respiratory infections [PDF]

open access: yes, 2019
Non influenza viral upper respiratory illnesses are responsible for a significant percentage of sick visits to primary care physicians. Patients who expect antibiotics are more likely to be given them, and this contributes to growing antibiotic ...

Expression of the CCCH-tandem zinc finger protein gene OsTZF5 under a stress-inducible promoter mitigates the effect of drought stress on rice grain yield under field conditions [PDF]

open access: yes, 2020
Increasing drought resistance without sacrificing grain yield remains an ongoing challenge in crop improvement. In this study, we report that Oryza sativa CCCH‐tandem zinc finger protein 5 (OsTZF5) can confer drought resistance and increase grain yield ...

Improvements of the Variable Thermal Resistance [PDF]

open access: yes, 2007
A flat mounting unit with electronically variable thermal resistance [1] has been presented in the last year [2]. The design was based on a Peltier cell and the appropriate control electronics and software. The device is devoted especially to the thermal

Mid-infrared LEDs versus thermal emitters in IR dynamic scene simulation devices [PDF]

open access: yes, 2006
In a radical departure from conventional thermal emitter-based dynamic IR scene simulation devices, we have tested InAsSbP/InAs LEDs grown by liquid phase epitaxy and tuned at several peak-emitting wavelengths inside the mid-IR band.

Electrical resistance determination of actual contact area of cold welded metal joints [PDF]

open access: yes, 1970
Method measures the area of the bonded zone of a compression weld by observing the electrical resistance of the weld zone while the load changes from full compression until the joint ruptures under tension.

Redefining awn development in rice through the breeding history of Japanese awn reduction

open access: yesFrontiers in Plant Science
The study challenges the conventional understanding of awn loss as a domestication syndrome, showing instead that many awned varieties continued to be widely grown in Japan until the early twentieth century and that selection for awn reduction was active

Application of molecular genetic methods in rice breeding for cold resistance

open access: yesЗерновое хозяйство России
Low positive temperatures have a negative impact on all processes occurring at all stages of rice development. This is especially true during the period of seed germination and sprouting, resulting in reduced seed energy and growth strength.

Strong enhancement of Jc in binary and alloyed in-situ MgB2 wires by a new approach: Cold high pressure densification

open access: yes, 2009
Cold high pressure densification (CHPD) is presented as a new way to substantially enhance the critical current density of in situ MgB2 wires at 4.2 and 20 K at fields between 5 and 14 T.
