We generalize the so-called “deflected anomaly mediation” scenario to the case where threshold corrections of heavy messengers to the sparticle squared-masses are positive. A concrete model realizing this scenario is also presented. The tachyonic slepton problem can be fixed with only a pair of messengers. The resultant sparticle mass spectrum is quite different from that in the conventional de...

Corrosion of steel in concrete reduces the life and durability of concrete structures. It is a worldwide problem, which causes heavy losses to the economy and industry. The corrosion of steel is inevitable. The durability of concrete structures primarily depends on the condition of the embedded steel in concrete, apart from any deterioration that the concrete may undergo. To determine the condi...

A subset of German function verbs can be used either in a full, concrete, 'heavy' ("take a computer") or in a more metaphorical, abstract or 'light' meaning ("take a shower", no actual 'taking' involved). The present magnetoencephalographic (MEG) study explored whether this subset of 'light' verbs is represented in distinct cortical processes. A random sequence of German 'heavy', 'light', and p...

<p>A prestressed concrete bridge was built in 1963 with BBRV cables. It has three spans and a total length of 134.8 m. Due to mining activities the loaded trucks weight 90 ton during 2012-2014 from 2019. Crack development been monitored manually 2020 strain gauges LVDTs. Cracks normally vary between 0.1 0.3 mm width grow time. In November some on showed alarming growth closed for traffic....

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...
