On the Problem of Shale Gas Mining in Ukraine
New sources of power resources are one of the most important and central
tasks for the human. In these latter days all energy-dependent countries develop
alternative technologies to produce renewable fuel: nuclear power, wind power, solar
power, innovative approaches on the basis of genetically modified organisms etc
Breast state improvement by using the lymphatic drainage disposable bra pads
Background: The health and good esthetic conditions of the breast are important indicators of women’s life quality. One factor that negatively affects this quality is the breast ptosis, associated with the sagging of the mammary glands due to tissue stretching and the loss of tissue and skin elasticity. New tools and methods able to improve the shape and beautiful contour of the breast are highly desirable.Methods: We investigated how the disposable bra pads by BAE International Inc., having the lymphatic drainage effect for the breast, influenced the female breast state. We applied two methods, the ultrasound elasticity imaging and the pattern recognition of the nipples position, to monitor the breast state dynamics in two groups of females, the study and control ones.Results: Preliminary results showed that both the breast elasticity and the pattern of nipple positions improved for females wearing the bra pads as compared to females wearing regular bras without pads (P<0.05 for the difference between the two groups of females).Conclusions: Overall, the bra pads by BAE can be considered as an effective tool encouraging metabolism by improving the flow of blood circulation and lymph in the breast
Reflection of electrons from a domain wall in magnetic nanojunctions
Electronic transport through thin and laterally constrained domain walls in
ferromagnetic nanojunctions is analyzed theoretically. The description is
formulated in the basis of scattering states. The resistance of the domain wall
is calculated in the regime of strong electron reflection from the wall. It is
shown that the corresponding magnetoresistance can be large, which is in a
qualitative agreement with recent experimental observations. We also calculate
the spin current flowing through the wall and the spin polarization of electron
gas due to reflections from the domain wall.Comment: 7 pages, 4 figure
