Shewanella, a group of ubiquitous bacteria renowned for respiratory versatility, thrive in environments where various electron acceptors (EAs) of different chemical and physiological characteristics coexist. Despite being extensively studied, we still know surprisingly little about strategies by which multiple EAs and their interaction define ecophysiology of these bacteria. Previously, we show...

The increasing cosmic ray statistics collected by present experiments and the future prospects with new large arrays demand accurate calculations of the extensive air shower parameters (EAS). The energy of the primary particle is estimated by ground arrays fitting a lateral distribution function (LDF) to the particle densities at a given observing level. However, the lack of appropriate paramet...

Ground-based cosmic ray experiments detect mainly by measuring the longitudinal and lateral distribution of secondary particles produced in extensive air shower (EAS). The EAS knee energy region is simulated via CORSIKA software. Several simulation samples with different energy, composition zenith angles were carried out to understand development electron, muon Cherenkov light EAS. All results ...

the images of muslims in media, literature and politics have been mostly black and white portrayals of a people alien to modernity, civilization, rationality and pluralism. since the end of the cold war and the onset of deadly terrorist attacks in different areas of the world, especially in the united states, these representations show a palpable difference: muslims are represented not only as ...

Quantum electrodynamics coupled-cluster (QED-CC) theory is used to model vacuum-field-induced changes ground-state properties of a series sodium halide compounds (NaX, X = F, Cl, Br, and I) strongly coupled an optical cavity. Ionization potentials (IPs) electron affinities (EAs) are presented, it demonstrated that EAs easily modulated by cavity interactions, while IPs for these far less sensiti...

cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...

assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...

We measured the air uorescence yield as a function of pressure with electrons between 1.4 MeV and 1000 MeV by means of a 90 Sr source and an electron beam. Results indicate that the uorescence yield is proportional to electron energy loss from 1.4 MeV to 1000 MeV. The dE dx relativistic rise in air is detected. We describe the pressure temperature dependency of air uorescence by a formula deriv...
