the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

We study the space-averaged electromagnetic (EM) fields weighted by energy density in central regions of heavy-ion collisions. These average quantities can serve as a barometer for magnetic-field induced effects such magnetic effect, chiral separation effect and wave. Comparing with at geometric center collision, are smaller early stage but damp slower later stage. The space squared well EM ano...

regardless of severity, earlier intervention to correct hearing loss in children improves speech development and conversational abilities. a cross-sectional study was performed on 230 neonates who were at risk of hearing loss in tehran university of medical sciences hospitals between september 2000 and february 2002. hearing was examined before the 3rd month by auditory brainstem responses (abr...

background: stillbirth is a sensitive indicator for health care quality, living conditions and equity in a society. the aim of this study was to determine the rate and contributing factors of stillbirth at babol hospitals. methods: this cross-sectional, descriptive, analytical study was designed as an applied research, using census sampling in 2012-2013. a questionnaire was applied for data col...

Anomaly perception of infrared point targets has high application value in many fields, such as maritime surveillance, airspace and early warning systems. This kind abnormality includes the explosion target, separation between stages, disintegration caused by abnormal strike, etc. By extracting radiation characteristics continuous frame targets, it is possible to analyze warn target state time....

in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...

Multistation observations of ionosphere scintillation at VHF (250 MHz) and GNSS L1 frequency from three locations – (i) Bokkhali (BOK) (geographic 21.6 N, 88.2 E, dip 31.48), (ii) Raja Peary Mohan College Centre (RPMC) (geographic 22.66 N, 88.4 E, dip 33.5) and (iii) Krishnath College Centre (KNC), Berhampore (geographic 24.1 N, 88.3 E, dip 35.9) – at∼ 1 latitudinal separations near the norther...

A bstract The long-standing muon g ? 2 anomaly has been confirmed recently at the Fermilab. combined discrepancy from Fermilab and Brookhaven results shows a difference theory significance of 4.2 ? . In addition, LHC updated lower mass bound pure wino. this letter, we study to what extent can be explained in mediation scenarios, where wino is dominant dark matter component. To end, derive some ...
