obtained during interviews with the ex-inhabitants of an abandoned village near the Igarapé do Urucú (a left affluent of the Rio Sucundurí, along the Serra do Sucundurí) indicates that M. acariensis and another species of marmoset with blackish hairs occur in the area. As M. melanurus has been confirmed as occurring in the Sucundurí Mountains (Noronha, unpubl. data), it is possible that these s...

The variation of forest types across Virginia reflects the diverse physiography of the state. From the sandy, low-elevation soils of the Coastal Plain to the dry, rocky soils on the southwestern slopes of the Appalachian Mountains, Virginia has one of the most diverse landscapes in the East (Fleming et al. 2006). Most forests in this area have been heavily influenced by anthropogenic disturbanc...

Flower morphology of 10 Fritillaria species of subgenera Theresia and Fritillaria growing wild in Iran is studied using seventy morphological characters. Qualitative and quantitative datasets separated taxa into subgenera, sectional and groups. Three enigmatic species F. caucasica, F. zagrica (endemic to Zagros Mountains) and F. pinardii (recently reported from Zagros Mountains) appeared as clo...

We report measurements of mesoscopic fluctuations of elastic cotunneling in Coulomb blockaded quantum dots. Unlike resonant tunneling on Coulomb peaks, cotunneling in the valleys is sensitive to charging effects. We observe a larger magnetic field scale for the cotunneling (valley) fluctuations compared to the peaks, as well as an absence of “weak localization” (reduced conductance at B ­ 0) in...

A specific sample area was selected, where an assessment model made for the stability of a slope subjected to anthropogenic impacts. hillside zone from foot Vitosha and Lozen mountains in southern periphery Sofia Kettle chosen as exemplary part hazards arising Trans-Balkan valleys. The impact on their studied three particular slopes. study is about 1.25 km2 has maximum distance up 3.80 km betwe...

In order to understand the dynamics of emergence and spreading socio-technical innovations population moves it is important determine place origin these populations. Here we focus on role geographical factors, such as land fertility mountains in context human evolution distribution dynamics. We use a constrained diffusion-based computational model, computer simulations analysis land-quality dat...

We develop a systematic treatment for the quasi-zero modes, which play an important role in nonabelian gauge theories. It can be used to derive the analytic forms for the constrained instantons in the Yang-Mills-Higgs theory. This will automatically sum up contributions to all orders in ρ, the instanton size. We also give the analytic expressions for the instanton-antiinstanton pair, with an ar...

The fact that Egypt falls within the arid and semi-arid areas, makes it always vulnerable to sudden storms, which have increased significantly during past ten years. Climate change is one of factors cause increasing storms frequency, intensity expansion cover new areas. During three days, from November 11 13, 2021, a severe storm hit city Aswan its suburbs, leaving behind extensive property dam...
