[1] There is increasing evidence that the amount of solar radiation incident at the Earth’s surface is not stable over the years but undergoes significant decadal variations. Here I review the evidence for these changes, their magnitude, their possible causes, their representation in climate models, and their potential implications for climate change. The various studies analyzing long-term rec...

given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. this study was conducted during 2012-2013 at the research center of agricultural university of tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. a...

a 16-year-old class ii female patient was treated without tooth extraction. the upper first molars were distalized by the pendulum appliance. after six months, the molars tipped significantly to the distal. to correct this side effect, we decided to upright the molars using skeletal anchorage. on each side, a mini-screw was inserted between first and second premolars in the buccal cortical plat...

Emerging dimming occurs in isolated solar active regions (ARs) during the early stages of magnetic flux emergence. Observed by Atmospheric Imaging Assembly, it features a rapid decrease extreme-ultraviolet (EUV) emission 171 \r{A} channel images, and simultaneous increase 211 images. Here, we analyze coronal thermodynamic properties to probe its physical origin. We calculate time-dependent diff...

background. orthodontic mini-implants provide skeletal anchorage for tooth movement. there are two designs of mini-implants, tapered and cylindrical, which exhibit different clinical characteristics, including possible micro-damage to cor-tical bone. complications such as peri-implantitis and pain after mini-implant placement are common. the aim of this study was to evaluate the effect of mini-...

This paper presents a streetlight management system, based on wireless communication technologies, which will provide tangible solutions to improve energy efficiency by adapting to the changes in the contextual needs. The proposed solution is said to be intelligent since light dimming is fixed based on the analysis of the data provided by the deployed sensors.
