Assessment of anaerobic co-digestion of food waste and wastewater solids for sustainable waste management in Yosemite National Park, USA
The growing need for sustainable municipal solid waste treatment and energy production has driven the development of new waste management methods like co-digestion. Anaerobic co-digestion of food waste (FW) and wastewater solids (WWS) has been implemented at a few wastewater treatments plants to efficiently treat organic wastes and produce methane-rich biogas as an energy source. Yosemite National Park has an opportunity to design a new co-digestion facility with an upcoming upgrade to their local wastewater treatment plant in El Portal, California. The Park annually produces approximately 5 million tons of primary WWS and 1 million tons of FW waste, with a volatile solid ratio of 70:30 FW to WWS, or 70% FW. Diverted FW is currently sent to the Mariposa County landfillβs compost facility. To measure the possible increase in biogas production associated with FW addition to WWS, a biochemical methane potential (BMP) test was done over 35 days under mesophilic conditions with treatment mixing ratios ranging from 0% to 100% FW on a volatile solids basis. Calculated annual methane production increased 3.25 times from 0% FW scenario (WWS only) versus a 70% FW scenario, translating to a potential increase in methane production at the wastewater treatment plant of 28,000 to 91,000 m3/yr. Results showed that if the wastewater treatment plant also implemented combined heat and power to combust the increased biogas from 70% FW co-digestion, potentially 920,000 kWh/yr could be produced to cover all electricity and heating needs. This research demonstrates that Yosemite National Park could combine FW and WWS to sustainably manage their organic waste in line with their Zero Landfill Initiative, as well as produce enough energy to fully power the El Portal wastewater treatment plant
The microscopic basis for phase-sensitive experiments for determination of the order parameter symmetry in Fe-based superconductors
We present a microscopic theory of dc Josephson current, based on the
construction of a coherent temperature Green function in the tight-binding
approximation, in junctions with multiband superconductors. This theory is
applied to the junctions with multiband Fe-based superconductors (FeBS)
described by anisotropic s-wave order parameter symmetries, which probably
realized in FeBS. We confirm microscopically the previously suggested crucial
experiment for determination of the type of the order parameter symmetry in
FeBS.Comment: 5 pages, 3 figure
Anomalous superconducting proximity effect and coherent charge transport in semiconducting thin film with spin-orbit interaction
We present a microscopic theory of the superconducting proximity effect in a
semiconducting thin film with spin-orbit interaction () in an external
magnetic field. We demonstrate that an effective 1D Hamiltonian which describes
induced superconductivity in in contact with a usual -wave
superconductor possesses not only spin-singlet induced superconducting order
parameter term, as commonly adopted, but spin triplet order parameter term
also. Using this new effective Hamiltonian we confirm previous results for a
normal current across contacts of with a normal metal and for a
Josephson current with the same with induced superconductivity,
obtained previously in the framework of the phenomenological Hamiltonian
without spin-triplet terms. However, a calculated current-phase relation across
the transparent contact between with induced superconductivity in
magnetic field and usual -wave superconductor differs significantly from
previous results. We suggest the experiment which can confirm our theoretical
predictions.Comment: 5 pages, 6 figure

Lingo-cultural interpretation of sacred phytonyms with clear inner form
Linguistics is full of cultural and historic content as language is both the basis and product of culture. Language being a means of communication, helps to get knowledge about the world, culture, mentality of certain people. Approach to the language from the point of view of sacred phytonyms makes it possible to study the character of paralogical thinking and gives a view of a naΓ―ve world picture. Sacred phytonymy deals with names of plants, having healing effect, a well as those which are connected with names of saints (positive characteristic) and evil (negative characteristic).Π―Π·ΡΠΊΠΎΠ·Π½Π°Π½ΠΈΠ΅ ΠΏΡΠΎΠ½ΠΈΠ·Π°Π½ΠΎ ΠΊΡΠ»ΡΡΡΡΠ½ΠΎ-ΠΈΡΡΠΎΡΠΈΡΠ΅ΡΠΊΠΈΠΌ ΡΠΎΠ΄Π΅ΡΠΆΠ°Π½ΠΈΠ΅ΠΌ, ΠΏΠΎΡΠΊΠΎΠ»ΡΠΊΡ ΡΠ·ΡΠΊ β ΠΎΡΠ½ΠΎΠ²Π° ΠΈ ΠΏΡΠΎΠ΄ΡΠΊΡ ΠΊΡΠ»ΡΡΡΡΡ.
