In June 2022 the author, a conservator-restorer of cultural heritage based in Canada, travelled to region Puno for professional visit develop expertise conservation at-risk heritage.

Introduction Conflict often leads to nonequilibrium fluctuations as attackers spread, host defences increase, and counter-attack evolves. Spatial processes play a crucial role when attack types arrive from other populations and import of matching defence follows. We focus on cytoplasmic male sterility (CMS), an ideal system in which to study the spatial dynamics of conflict. Cytoplasmically inh...

for different agronomic traits in sunflower (helianthus annuus l.) inbred lines were estimated using “line × tester” analysis method. six new restorer lines were crossed with four cms lines as tester in 2006 growing season. the 24 f1 single cross combinations were planted in complete randomized block design with four replications in khoy field research station in 2007 growing season. there were...

-Dynamic Voltage Restorer (DVR) is a device used to mitigate voltage sags which are a significant power quality issue. This paper involves mathematical calculation for leading series voltage injection for mitigation of sags thereby achieving utility power factor improvement as well as power sharing between DVR and utility as per requirement and available distributed generation. Mathematical der...

Power quality is one of major problems in the presence era. It has become importance especially, with the introduction of sophisticated devices, whose performance is very sensitive to quality of power supply. power quality problem is an occurrence manifested as a nonstandard voltage,current,or frequency that results in a failure of end use euipement.One of the major problem deal here is the vol...
