Abstract The surface of nano silica (NS) was modified by [3- (2-Aminoethyl) aminopropyl] trimethoxy silane (KH-792) to increase activity. Evaluate the efficiency grafting into NS characterized Fourier Transform Infrared Spectrometry (FTIR) and Thermo Gravimetric Analysis (TGA). (m-NS) were dispersed epoxy resin Epon 1001X75 mechanical stirring ultrasonic vibration. Epoxy cured with Epikure 3125...

We have studied, in bilayer graphene (BLG), the hot electron cooling power FVP (T, ns) due to acoustic phonons via vector potential (VP) coupling. It is calculated as a function of electron concentration ns and temperature T and compared with FDP (T, ns) that due to deformation potential coupling. For the ns around 1x10 12 cm, FVP (T, ns) is much smaller than FDP (T, ns). With increase of ns, F...

We argue that a semi-infinite D6-brane ending on an NS5-brane can be obtained from the condensation of the tachyon on the unstable D9-brane of type IIA theory. The construction uses a combination of the descriptions of these branes as solitons of the worldvolume theory of the D9-brane. The NS5-brane, in particular, involves a gauge bundle which is operator valued, and hence is better thought of...

We present a Bluetooth LAN Access Point (LAP) simulator that we have developed to study pervasive application behavior under Bluetooth local connectivity. Our goal is to explore the impact on IP applications caused by the underlying Bluetooth protocol. Our simulator implements detailed processing of upper layers of Bluetooth LAP stack, including PPP, RFCOMM, and L2CAP. For lower layers, it trie...

A study was conducted to examine effects of mating systems composed of natural service (NS) and AI in swine on farrowing rate, litter size, and labor requirements. Sows and gilts were bred once per day via one of the following treatments (d 1/d 2): NS/NS, NS/AI, AI/AI, and NS/none. Gilts bred with NS/AI, AI/AI, and NS/NS had higher (P less than .05) farrowing rates than gilts bred with NS/none ...

In this paper we present our work on designing and implementing an ns-3 model for MultiPath TCP (MPTCP). Our MPTCP model closely follows MPTCP specifications, as described in RFC 6824, and supports TCP NewReno loss recovery on a per subflow basis. Subflow management is based on MPTCP’s kernel implementation. We briefly describe how we integrate our MPTCP model with ns-3 and present example simu...

Action potentials, which define electrical excitability, depend on the activity of voltage-gated Na, Ca and K (Kv) channels (see the review in this issue by Sanguinetti and Tristani-Firouzi, p. 463). But electrical activity without modulation would be like an automobile with one speed, no steering and no brakes. In addition to the channels that play the leading parts, bio-electric signalling in...

Investigators since Freud have appreciated that memories of the people, places, activities and emotions of daily life are reflected in dreams but are typically so fragmented that their predictability is nil. The mechanisms that translate such memories into dream images remain largely unknown. New research targeting relationships between dreaming, memory and the hippocampus is producing a new th...
