This article summarizes the results of the research papers presented at the International Symposium on pine wilt disease （IUFRO Working Party Meeting 4.04.03） held in July 2009, at Nanjing, China. The general topics covered were on pine wilt disease （PWD）, its causal organism, the pinewood nematode （PWN） Bursaphelenchus xylophilus, plus other PWN-associated microorganisms that play a significant role in PWD such as bacteria （e.g. Pseudomonasfluorescens）. Most of the papers that are reviewed are based on work on PWD-PWN in East Asia and Russia. Specific topics covered include： 1） the fundamental conceptions of PWD development, 2） pathogenicity, 3） host-parasite relationships including the histopathology of diseased conifers and the role of toxins from bacteria-nematode ecto-symbionts, 4） PWN life cycle and transmission, 5） B. xylophilus dissemination models, 6） associations （with other nematodes）, 7） diagnostics, 8） quarantine and control of the PWN and 9） biocontrol of the PWN.

In this paper we resolve the grandfather paradox in non-quantum and quantum gravitation theories for time travelling in a time wormhole. For macroscopic bodies, the main solution is alignment of the thermodynamic time arrows, resulting in the time traveller destroying. For microscopic bodies and for small probability cases of macroscopic bodies, the main solution is fracture of the time wormhole. As a result, multi-world system appears. These explanations are similar in non-quantum and quantum gravity. On the contrary, we can clarify some problems of quantum gravity by this consideration. “Indestructible finite gravitation interaction of an observer with an observable system (resulting in the time arrows alignment)” and “instability with respect to even infinitesimally small interaction in the gravitation theory” can resolve the wave function reduction paradox of quantum mechanics.

Soils developed from the Quaternary loesslike loams have been studied in the south of the forest-steppe zone on the Central Russian Upland. A polygenetic nature of the soil profile on the loesslike loams is shown. The modem pedogenetic processes in this soil ensure its eluvial-illuvial differentiation with the development of multilayered coatings in the illuvial horizon. The middle horizons in the studied soil profiles are referred to as textural （clay-illuvial） horizons. Differences in physical soil properties （bulk density, airconductivity, texture, water content, and temperature dynamics） were studied in the soil on the loesslike loam.

Facing common security threats, leaders of six countries-Russia, China, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan-established the Shanghai Cooperation Organization in June 2001 to maintain regional stability and security, fight terrorism and extremism, prevent conflicts and enhance economic cooperation. The SCO's primary goals are economic cooperation and fighting terrorism.

The Trans-Baikal geographical region is located in southeastern Siberia, Russia, east towards Lake Baikal and include the Daurian steppes. The steppes provide important habitats for several species of cranes, including the Red-crowned Crane (Grus japonensis). I have studied the cranes in the area since 1988. The Red-crowned Crane mainly occurs in the Torey Depression (Torey Lake) and the Argun River, which represent the far western edge of the breeding area for the continental population of the Red-crowned Crane. There are some scattering records of the cranes in the Torey Depression from before 1990. The birds appeared regularly and bred from 2002–2007 at Torey Lake. There have been no records since 2008 due to the fact that the wetlands have dried out during the regional climate cycle in the Torey Depression. Three or four individual Red-crowned Cranes have been sighted in Argun in the early 2000’s and then the numbers increased steadily until 2004. At the highest peak in 2004, there were at least 30 pairs of the cranes breeding in the wetlands of the river floodplain. Since then, with the reduced water flow in the Argun River and more and more wetlands drying out, the Red-crowned Crane population decreased dramatically to four or seven territories. The cranes are facing serious threats in the Argun River, such as frequent spring fires, poaching and water pollution. We need to unify efforts from both the Russian and Chinese sides to protect the cranes and their wetland habitat in the area.

Wind farms generally consist of a single turbine installed with the same hub height. As the scale of turbines increases,wake interference between turbines becomes increasingly significant, especially for floating wind turbines(FWT).Some researchers find that wind farms with multiple hub heights could increase the annual energy production(AEP),while previous studies also indicate that wake meandering could increase fatigue loading. This study investigates the wake interaction within a hybrid floating wind farm with multiple hub heights. In this study, *** is employed to simulate a hybrid wind farm which consists of four semi-submersible FWTs(5MW and 15MW) with two different hub heights. Three typical wind speeds(below-rated, rated, and over-rated) are considered in this paper to investigate the wake meandering effects on the dynamics of two FWTs. Damage equivalent loads(DEL) of the turbine critical components are computed and analyzed for several arrangements determined by the different spacing of the four turbines. The result shows that the dynamic wake meandering significantly affects downstream turbines’ global loadings and load effects. Differences in DEL show that blade-root flapwise bending moments and mooring fairlead tensions are sensitive to the spacing of the turbines.
