Airway gastric fistula (AGF) is a rare but catastrophic complication after esophagectomy. Surgical repair with viable tissue interposed between the airway and alimentary tracts remains the definitive treatment. However, it is challenging for surgeons, and only anecdotally described in sporadic case reports due to the complexity of the techniques necessary for successful surgical intervention. H...

The 1°gAg nuclear magnetic resonance line in a sample of polycrystalline AgF is observed to broaden substantially when the 19F spins are irradiated near the magic angle in their rotating frame. This is due to the reduction of 19F-19 F dipolar coupling, which normally causes fluctuations in the 19F-l°9Ag interactions (Abragam and Winter), inducing an exchange narrowing analogous to classical mot...

The Douglas–Kroll transformed Dirac–Coulomb Hamiltonian is used to describe scalar-relativistic effects in solids. A Hartree–Fock approximation with periodic boundary conditions makes it feasible to use methods originally developed for atoms and molecules to solve the corresponding equations for crystalline systems. The implementation is realized within the CRYSTAL program. Scalar-relativistic ...

Members of the anaerobic gut fungi (AGF) reside in rumen, hindgut, and feces of ruminant and non-ruminant herbivorous mammals and reptilian herbivores. No protocols for gene insertion, deletion, silencing, or mutation are currently available for the AGF, rendering gene-targeted molecular biological manipulations unfeasible. Here, we developed and optimized an RNA interference (RNAi)-based proto...

The Artificial Ground Freezing (AGF) method, which is widely used in tunnel excavations, significantly affects the properties of geotechnical materials frozen walls under extremely low temperatures. In order to simulate AGF process, freezing treatment with a temperature −30°C and thawing 25°C were performed on natural specimens granite residual soil (GRS). Subsequently, triaxial (TRX) tests con...

Artificial ground freezing (AGF) technology has been commonly applied in tunnel construction. Its primary goal is to create a frozen wall around the profile as hydraulic barrier and temporary support, but it inevitably affected by two natural factors. Firstly, seepage flows provide large continuous heat energy prevent soil from freezing. Secondly, key parameter transfer, thermal conductivity sh...

The food-borne pathogen Salmonella enterica serovar Typhimurium invades mammalian epithelial cells. This multistep process comprises bacterial binding to the host cell, activation of the Salmonella type three secretion system 1 (T1), injection of effector proteins, triggering of host cell actin rearrangements, and S. Typhimurium entry. While the latter steps are well understood, much less is kn...

Nuclear magnetic resonance (NMR) can help to collect soft clay pore size data. This paper uses NMR study the effect of freezing duration, gap time between two actions and thawing temperature on distribution (PSD) in clay. It was found that most progress completed during first hours. A longer second cycles leads greater structural damage. An appropriate results less subsidence induced by artific...

Research has been carried out on the analysis of physic properties green bean extract powder (Phaseolus vulgaris L). This study aims to determine physical characteristics that stored in a predetermined time variation. The tested included water content, solubility and organoleptic tests. results sample content test with storage variations less than 1, 2 3 months respectively were 5.55%, 2.86%, 3...
