The uncertainties in Antarctic climate reconstructions due to scarcity of proxy records have restricted the understanding mechanisms change, and further hindered improvement models. Here, we provide a new record derived from water stable isotopes Dome A, East Antarctica ice core. Together with six other core records, A is used investigate temperature changes Plateau (EAP) during period 1–1900 C...

As the demand for food and fiber grew during the past 300 years, because of the Earth’s expanding human population and rising per capita incomes, society met this demand first by increasing the land area under cultivation and later by improving crops so that their yields were higher. Before 1900, land was abundant almost everywhere, and in the United States, new lands were brought into producti...

Jacques Loeb [5] broadened and corrected his earlier claims concerning artificial parthenogenesis [6] in sea urchins in a series of experiments in 1900. He published these findings, ?Further Experiments on Artificial Parthenogenesis [4] and the Nature of The Process of Fertilization,? in a 1900 issue of The American Journal of Physiology. His new results amended those from earlier experiments h...

We present a nucleon resonance analysis by simultaneously considering all pionand photon-induced experimental data on the final states γN , πN , 2πN , ηN , KΛ, KΣ, and ωN for energies from the nucleon mass up to √ s = 2 GeV. In this analysis we find strong evidence for various higher lying resonances as, e.g., the P13(1900). The ωN production mechanism is dominated by large P11(1710) and P13(19...
