State-owned forestry enterprises are important elements of the forestry economy in China. The operational efficiency of such enterprises depends on technological progress and other input factors. Total factor productivity (TFP) is an important means to evaluate the efficiency of technical elements. The growth of production efficiency can be classified into efficiency variation and technical var...

Paleoseismic trenching and fault surface trace mapping indicate that the Olinghouse fault zone, a northeast trending, left-lateral strike-slip fault located in the northern Walker Lane, Nevada, has been the source of multiple latest Pleistocene and Holocene surface-rupturing earthquakes. A trench exposure near the eastern end of the fault records two, and possibly three, earthquakes after 3360 ...

Phylogenetic analyses of rbcL sequences demonstrate that Calliarthron as currently constituted is paraphyletic. Calliarthron yessoense and C. latissimum from the northwest Pacific belong in Alatocladia and are conspecific. After the transfer of C. yessoense and C. latissimum, Calliarthron is monophyletic, known only from the northeast Pacific and comprises two species, C. cheilosporioides and C...

Imnaha Basalt and Grande Ronde Basalt (RI) of the Columbia River Basalt Group form a small synclinal basin immediately west of Riggins, Idaho. The displacement of the margins of the basalt outcrop, of the synclinal axis, and of a dike of Saddle Mountains(?) Basalt define a pattern best explained by a model of west-northwest to eastsoutheast and north-northwest to south-southeast dextral strike-...

Trends in the annual flux of sulfate and nitrate in a new ice core collected at an elevation of 3017 m on Eclipse Icefield, 45 km northeast of Mt. Logan were examined to determine the effect of anthropogenic activity on precipitation chemistry in the remote northwest North American midtroposphere. The annual flux of both sulfate and nitrate at Eclipse began increasing in the 1940s, demonstratin...

2 ABSTRACT A seasonal forecast system based on a global, fully coupled ocean-atmosphere general circulation model is used to (i) evaluate the interannual predictability of the Northwest Pacific climate during June-August following El Niño [JJA(1)], and (ii) examine the contribution from the tropical Indian Ocean (TIO) variability. The model retrospective forecast for 1983-2006 captures major mo...

a. Country profile Vietnam, officially the Socialist Republic of Vietnam, is the easternmost nation on the Indochina Peninsula. It borders China to the north, Laos to the northwest, and Cambodia to the southwest. On the country's east coast lies the South China Sea. The capital of Vietnam is Hanoi and the largest and most populous city is Ho Chi Minh City. Vietnam, with its 4-level administrati...

For more than thirty years, it has been recognized that the dentition of the Indians of the Alaskan Interior and Pacific Northwest has crown and root trait frequencies that are often intermediate between those of Eskimo-Aleuts and all North and South American Indians. When many dental morphological variables are assessed simultaneously, tooth-based distance values show that Na-Dené/Greater Nort...

Late Quaternary slip rates and satellite-based geodetic data for the western Great Basin constrain regional fault-slip distribution and evolution. The geologic slip rate on the Fish Lake Valley fault zone (the northwest extension of the Furnace Creek fault zone) increases northward from about 3 to 5 mm/yr, in agreement with modeled geodetic data. The increase coincides with the intersections of...

We summarize the results of studies of mitochondrial DNA sequence variation in Atlantic cod (Gadus morhua) from the North Atlantic and adjacent areas. Population genetic structures in the Northwest and Northeast Atlantic and Barents Sea differ markedly. Whereas all populations from the Northwest Atlantic are dominated by a single common genotype and show low haplotype and nucleotide diversity, ...
