Homogenization by blow-up
No full textIn this article we highlight how the Fonseca and Muller blow-up technique is particularly well suited for homogenization problems. As examples we give a simple proof of the non-linear homogenization theorem for integral functionals and we prove a homogenization theorem for sets of finite perimeter

Jusa and Barsuchi Log volcanogenic massive sulfide deposits from the Southern Urals of Russia: Tectonic setting, structure and mode of formation
No full textThe Jusa and Barsuchi Log volcanogenic massive sulfide (VMS) deposits formed along a paleo island arc in the east Magnitogrosk zone of the Southern Urals between ca 398 and 390 Ma. By analogy with the VMS deposits of the west Magnitogrosk zone, they are considered to be Baimak type deposits, which are Zn-Cu-Ba deposits containing Au, Ag and minor Pb. Detailed mapping and textural analysis of the two deposits shows that they formed as submarine hydrothermal mounds which were subsequently destroyed on the sea floor under the influence of ocean bottom currents and slumping. Both deposits display a ratio of the length to the maximum width of the deposit > 15 and are characterized by ribbon-like layers composed mainly of bedded ore and consisting principally of altered fine clastic ore facies. The Jusa deposit appears to have formed in two stages: deposition of colloform pyrite followed by deposition of copper-zinc-lead sulfides characterized by the close association of pyrite, chalcopyrite, sphalerite, galena, tennantite, arsenopyrite, marcasite, pyrrhotite, bornite, native gold and electrum and high concentrations of gold and silver. The low metamorphic grade of the east Magnitogorsk zone accounts for the exceptional degree of preservation of these deposits
Jusa and Barsuchi Log volcanogenic massive sulfide deposits from the southern Urals of Russia: Devonian analogs of the Kuroko deposits of NE Honshu, Japan
No full textChemical analysis of 60 samples from the Jusa and Barsuchi Log volcanogenic massive sulfide (VMS) deposits by inductively coupled plasma-mass spectrometry shows that, on average, the Jusa deposit is more enriched in the chalcophilic elements than the Barsuchi Log deposit, whereas the Barsuchi Log deposit is more enriched in the lithogenous elements and Te. In addition, the yellow ores in these deposits are more enriched on average in Cu, As and Mo and the black ores more enriched in Zn, Ga, Cd, Sb, Ba, Hg and Pb relative to each other. Both these deposits are similar in composition to the Kuroko deposits of NE Honshu and may be considered to be analogs of these deposits. The Kuroko deposits, however, contain much higher concentrations of As, Ag, Sb, Ba, Hg and lower contents of Te on average than the Jusa and Barsuchi Log deposits. Based on the higher contents of Te in the Barsuchi Log deposit compared to the Jusa deposit, as well as on textural considerations, it is concluded that the Barsuchi Log deposit is intermediate between the Urals- and Kuroko-type deposits, whereas the Jusa deposit is more analogous to the Kuroko-type deposits. Based on the compositional data presented here, the Jusa and Barsuchi Log deposits may be described as Zn-Pb-Cu-Ba deposits rather than as Zn-Cu-Ba deposits, as the Baimak-type deposits of the west Magnitogrosk zone have previously been described
Eubiotic effect of rifaximin is associated with decreasing abdominal pain in symptomatic uncomplicated diverticular disease: results from an observational cohort study
No full textBackground: Rifaximin effectively treats symptomatic uncomplicated diverticular disease (SUDD) and has shown eubiotic potential (i.e., an increase in resident microbial elements with potential beneficial effects) in other diseases. This study investigated changes in the fecal microbiome of patients with SUDD after repeated monthly treatment with rifaximin and the association of these changes with the severity of abdominal pain. Methods: This was a single-center, prospective, observational, uncontrolled cohort study. Patients received rifaximin 400 mg twice a day for 7 days per month for 6 months. Abdominal pain (assessed on a 4-point scale from 0 [no pain] to 3 [severe pain]) and fecal microbiome (assessed using 16 S rRNA gene sequencing) were assessed at inclusion (baseline) and 3 and 6 months. The Spearman’s rank test analyzed the relationship between changes in the gut microbiome and the severity of abdominal pain. A p-value ≤ 0.05 was considered statistically significant. Results: Of the 23 patients enrolled, 12 patients completed the study and were included in the analysis. Baseline abdominal pain levels decreased significantly after 3 (p = 0.036) and 6 (p = 0.008) months of treatment with rifaximin. The abundance of Akkermansia in the fecal microbiome was significantly higher at 3 (p = 0.017) and 6 (p = 0.015) months versus baseline. The abundance of Ruminococcaceae (p = 0.034), Veillonellaceae (p = 0.028), and Dialister (p = 0.036) were significantly increased at 6 months versus baseline, whereas Anaerostipes (p = 0.049) was significantly decreased. The severity of abdominal pain was negatively correlated with the abundance of Akkermansia (r=-0.482; p = 0.003) and Ruminococcaceae (r=-0.371; p = 0.026) but not with Veillonellaceae, Dialister, or Anaerostipes. After 3 months of rifaximin, abdominal pain was significantly less in patients with Akkermansia in their fecal microbiome than in patients without Akkermansia (p = 0.022). Conclusion: The eubiotic effect of rifaximin was associated with decreased abdominal pain in patients with SUDD

Factory Kitchen, Samara, 1931, by Ekaterina Maksimova
No full textThe Maslennikov factory canteen, also known as the Fabrika Kukhnya or Factory Kitchen, was a canteen producing meals on industrial scale, a vital typology for the early Soviet urbanism.
Factory Kitchen in Samara belonged to the Maslennikov Factory. The building is absolutely unique in its plan in the shape of a hummer-and cycle, symbol of the union of the working people. The "hummer" held the kitchen and storage, and the "cycle" was occupied by dinner-halls
Battery Energy Storage Systems as a Game Changer in the Transformation of Global Power Industry
No full textSolar and wind electricity generation has increased more than 6 times during the past decade and the share of these energy sources in electricity production in some countries has already reached 30% or more. The dependents of solar and wind power plants on weather conditions significantly increases the requirements for the level of system flexibility in the electric power industry, which are going to grow as the low-carbon paradigm advances. The article focuses at the analysis of the prospects for the development of battery energy storage technologies as the main source of increasing the ability of the power system to effectively adapt to the changes in demand and supply over different time horizons. The author shows that, firstly, the abrupt acceleration in the rate of commissioning of large-scale stationary electricity storage systems in 2020–2021 is of a long-term nature and is due not only to a significant reduction in the cost of lithium-ion batteries, but also to state support and special tuning of electricity markets regulation in the United States, China and some European countries. Secondly, the competition among manufacturers in the lithium-ion battery market is bound to intensify. Thirdly, existing technologies allow only intraday storage of electricity with acceptable costs. The development of a lowcost method for long-term storage of electricity could radically expand the boundaries of variable renewable energy sources and open the way to achieving carbon neutrality. Many large companies and small start-ups, as well as leading universities and laboratories, are actively searching for such a technology with the support of government funding and private financing, including venture capital
