While the SCN controls the circadian clock, further evidence suggests the existence of a food-entrainable oscillator (FEO) that links behavior to changes in food availability such as during restricted feeding (RF). We found that the activity of AgRP/NPY neurons changed rhythmically during RF suggesting that these neurons are a component of the FEO. We next ablated AgRP/NPY neurons in neonates w...

Developments of large-scale energy storages with not only low cost and high safety but also abundant metals are significantly demanded. While lithium ion batteries are the most successful method, they cannot satisfy all conditions. Here we show the principle of novel lithium-free secondary oxygen rocking aqueous batteries, in which oxygen shuttles between the cathode and anode composed of iron-...

Deutsche Bahn (DB) operates a large fleet of rolling stock (locomotives, wagons, and train sets) that must be combined into trains to perform rotations. This composition is special characteristic railway operations distinguishes rotation planning from the vehicle scheduling problems prevalent in other industries. DB models compositions using hyperarcs. The resulting hypergraph are addressed nov...

Abstract Piezoelectric nanogenerators (PENG) with flexible and simple design have pronounced significance in fabricating sustainable devices for self-powering electronics. This study demonstrates the fabrication of electrospun nanocomposite fibers from polyvinylidene fluoride (PVDF) filled zinc oxide (ZnO)/iron (FeO) nanomaterials. The fiber based PENG shows piezoelectric output voltage 5.9 V w...

This work aims to characterize serpentine soils in Bulgaria and examine the biogeochemistry of pedogenic Ni its relation available forms. Soils were collected from Eastern Southern Rhodopes (Bulgaria). The chemical composition is similar Balkan Peninsula characterized by high contents (919.9–2397.2 mg.kg–1). had a neutral slightly alkaline reaction (pH 6.4 7.6) medium organic matter content. Of...

In order to better understand and develop the technology of integrating dephosphorization decarburization in a single converter (abbreviated as IDDSC), relevant thermodynamic issues were discussed by calculation. Based on calculation, bridges between phosphorus distribution ratio, temperature, slag composition constructed. Besides, connections behavior microstructure also established investigat...

The densities of 10 melts in the CaO-FeO-Fe20,-Si02 system were determined in equilibrium with air, in the temperature range of I200 to 1550°C. using the double-bob Archimedean technique. Melt compositions range from 6 lo 58 wt% SK&, 14 lo 76 wt% Fe20j and 10 lo 46 wt% CaO. The ferric-ferrous tatios of glasses drop-quenched from loop fusion equilibration experiments were determined by “Fe Mhbau...

Introduction: There have been several approaches to develop remote sensing technique to estimate composition of the lunar surface using multispectral observations. We present a new approach based on statistical analysis of spectral and compositional data for lunar samples by the Lunar Soil Characterization Consortium (LSCC) and using the UVVIS Clementine data with 1 km resolution. This techniqu...
