(Klingler et al., 2005). Mi-1.2 and Vat both are single dominant R genes but exhibit differential mechanism of inhibition to aphids. Resistance conferred by Mi-1.2 gene results in aphid starvation and desiccation while that of Vat gene retards growth of aphid population by decreasing fitness ...

This paper examines the age structure, growth parameters, maturity, age at first capture, optimum length, natural and fishing mortality and amount of biomass in the southern Caspian Sea (Iranian waters), during a two decades time series period from 1990–1991 to 2008–2009. For a pooled data...
4) of a 1:1 mixture of 12(+•) and CBPQT2(+•) in CD3CN, presumably because of a small thermal population of a paramagnetic state at room temperature45,49. Upon cooling to –20 °C, the signals of the complex are individually resolved, yet remain broad until further cooling ...
They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. If the young foxes continued to show aggressive response, even after significant human contact, they were thrown away from the populationmeaning they were...
Total grain production increased, as well as exports, even with rising domestic demand from population growth. As a result, there was a slow improvement in the living standards of Russian peasants in the Empire’s last two decades before 1914. Recent research into the physical stature of Army ...
Some observers have noted that Russian GDP y/y has not collapsed in Q1 (the latest reported data). Note that 3.5% y/y reading is exactly that — year-on-year growth, which encompasses about one month of the post-sanctions period (the expanded invasion of Ukraine started on February 24th...
Russian petroleum industry plays a vital part in both the country’s economy and international hydrocarbon market, providing a third of state budget revenues and over 13% of global liquid hydrocarbon exports. Yet, nowadays the industry is facing a number of serious challenges, which threaten to un...
