BACKGROUND Traditional Environmental Knowledge (TEK) related to truffles represents an under-investigated area of research in ethnobiology. Nevertheless, truffles, in a few southern European areas, and notably in South Piedmont, represent a crucial component of the local economy and cultural heritage. METHODS Thirty-four white truffle (Tuber magnatum Pico) gatherers, locally known as trifulau...

In the thousands of years development and evolution ancient China, sometimes it split, unified, but after each division, there would be greater unification, which is law division unification in Chinese history. Why does this come into being? The study found that are two fundamental reasons: one all major ethnic groups China have common blood origin. Second, based on same root homology, complex ...

The objective was to identify factors of competitiveness and sustainability in livestock systems Andean-Amazonian Piedmont. In a sample 60 farms the area, survey aimed at producers implemented internal external for sustainability. Data envelopment analysis used measure technical efficiency an econometric model determinants key towards were profitability cattle forest extension within farms. red...

Interruption of monsoon rainfall by prolonged spells of sparse rainfall (break-monsoon) during the midmonsoon months of July and August over the plains of northern India (20°-29'N, 75O-85'E) has been investigated. When a tropical low-pressure system moves from the plains in a northerly direction toward the submontane region of the Himalaya, the monsoon trough of low pressure also moves from the...

dust storms are known as hazardous problems in western part of iran. iraq is one of the main sources for dust storm arriving to the western part of iran. the radial basis function network model (rbfn) has been used to assess wind erosion hazards in the source area of dust storms over several western iranian cities. normalized difference salinity index (ndsi) was used to determine the changes in...

Development of rural areas in rivers margins and flood plains, without understanding and attention to the dynamical and hydrological conditions and upstream areas of the rivers will cause to increase flood risk and loss of life and financial. Flood zoning has many applications, in floodplain management. For management of the three major branches of the Halilrood River, Rabor, Roodar and Javaran...

We present maps of the topographic roughness of the northern circumpolar area of 30 Mercury at kilometer scales. The maps are derived from range profiles obtained by the 31 Mercury Laser Altimeter (MLA) instrument onboard the MErcury Surface, Space 32 ENvironment, Geochemistry, and Ranging (MESSENGER) mission. As measures of 33 roughness, we used the interquartile range of profile curvature at ...

In the last few decades several studies have examined temporal trends in the incidence of childhood cancer in various Western countries. These reports have focused mainly on leukemia brain tumors, and to a lesser extent on rarer childhood neoplasms. The findings are not consistent, with differing patterns for different cancer sites and in different countries. Several papers have reported an inc...

[1] Lobate scarps on Mercury are the surface expression of thrust faults and are generally thought to be the result of global contraction. Our analysis indicates that these thrust faults are not uniformly distributed and exhibit non-random patterns on the imaged hemisphere. The greatest area normalized cumulative length of the faults occurs in the southern hemisphere, below 50 S. The thrust fau...
