in this paper, new definitions of $l$-fuzzy closure operator, $l$-fuzzy interior operator, $l$-fuzzy remote neighborhood system, $l$-fuzzy neighborhood system and $l$-fuzzy quasi-coincident neighborhood system are proposed. it is proved that the category of $l$-fuzzy closure spaces, the category of $l$-fuzzy interior spaces, the category of $l$-fuzzy remote neighborhood spaces, the category of ...

Human bestrophin-1 (hBest1) is a calcium-activated chloride channel from the retinal pigment epithelium, where mutations are associated with vitelliform macular degeneration, or Best disease. We describe the structure of a bacterial homolog (KpBest) of hBest1 and functional characterizations of both channels. KpBest is a pentamer that forms a five-helix transmembrane pore, closed by three rings...

Surgical management of tuberculosis is uncommon in children. We report a case of a 14-month-old boy with miliary tuberculosis and recurrent pneumothorax due to cavities in the left lung. This boy had no previous medical history and was referred to our hospital for a severe pneumonia. Initial chest radiograph showed bilateral miliary pattern. Direct microscopy of gastric lavage showed the presen...

With the rapid development of national economy and increasing demand for energy, acceleration natural gas storage strategies, underground has become more important in China’s oil consumption energy safety. Underground salt cavern many advantages is very suitable peak shaving?However, most rocks China are layered beds, some beds deeply buried. This article introduces history deep technical chall...

Open wound managment after perforated appendicitis has been a common practice but recently, primary closure has been advocated to reduce costs and morbidity. For comparing delayed closures against primary closure with vacuum drainage, a randomized experimental study was designed. in Kerman. Sixty patients with perforated appendicitis divided randomly in two groups and evaluated on day of discha...

We show that for excellent, normal equicharacteristic rings with perfect residue fields the tight closure of an ideal is contained in its axes closure. First we prove this characteristic p. This achieved by using notion special established Huneke and Vraciu. By reduction to positive containment also holds 0. From deduce a ring finite type over C primary inside continuous

Geophysical studies over Kartchner Caverns State Park mapped structure and groundwater patterns beneath valley alluvium and determined the geophysical expression of the caverns at the surface. Three techniques were employed: electromagnetics (EM), gravity, and natural potential (NP). Electromagnetic traverses in the area failed to detect the voids, owing to the very low conductivity of the carb...

In this paper we present an algorithm for the valuation and optimal operation of natural gas storage facilities. Real options theory is used to derive nonlinear partial-integro-differential equations (PIDEs) for the valuation and optimal operating strategies. The equations are designed to incorporate a wide class of spot price models that can exhibit the same time-dependent, mean-reverting dyna...

Hydrogen pipeline systems offer an economical means of storing and transporting energy in the form of hydrogen gas. Pipelines can be used to transport hydrogen that has been generated at solar and wind farms to and from salt cavern storage locations. In addition, pipeline transportation systems will be essential before widespread hydrogen fuel cell vehicle technology becomes a reality. Since hy...

in eukaryotes, vesicle trafficking is regulated by the small monomeric gtpases of the rab protein family. rab11, (a subfamily of the ypt/rab gene family) an evolutionarily conserved, ubiquitously expressed subfamily of small monomeric rab gtpases, has been implicated in regulating vesicular trafficking through the recycling of endosomal compartment. in an earlier communication, we have shown th...
