The paper presents the results of experimental studies use graphene nanotubes to increase thermal conductivity a phase-changing material. Graphene were dispersed in molten paraffin by ultrasonic treatment an amount 0.1–0.5 wt.%. obtained samples with examined on scanning calorimeter. All different content during heating and cooling DSC curves had two peaks corresponding phase transitions main h...

This case report describes the treatment of uterine prolapse in a bitch with vulval ligature technique after rejection uterine. A two-year-old Golden Retriever was brought complaint protruded dystocia. After edema removed, it lubricated paraffin liquid and rejected inside. this procedure, procedure applied to upper third vulva. treatment, observed that did not recur patient recovered. It learne...

background: the heartworm disease is an infectious disease of dogs with dirofilaria immitis combined with cardiovascular and circulatory abnormalities. the heartworm disease can become a serious health risk when associated with a severe infection. in this study, a male, 8 year-old dog that died suddenly was necropsied and all tissues were examined grossly. methods: major organs including heart,...

The net absorption of fluid and electrolytes by the mammalian small intestine may be changed to a state of net secretion by the administration of agents that elevate the cyclic AMP content of the mucosal epithelium, e.g. cholera toxin, theophylline, dibutyrylcyclic AMP [for reviews see Banwell &Sherr(1973),Sladen(1973), Field(1974) and Kimberg (1974)l. In contrast with the wealth of data on the...

Hybrid rockets have many advantages over pure solid or liquid propellant rockets, but low fuel regression rates and correspondingly thrust hindered their application to operational systems. Paraffin-based fuels regress significantly faster than traditional polymeric formulations, such as HTPB, paraffin inclusion in HTPB represents a potential tool for performance augmentation hybrid rockets. A ...

Liquid paraffin can be used as a coolant fluid in electronic and cutting devices due to its suitable capabilities such as electrical insulating, high heat capacity, chemical, and thermal stability, and high boiling point. In this study, the dynamic viscosity of paraffin containing the alumina nanoparticles has been examined experimentally. The nanofluids with different composition of alumina (0...

Abstract: A novel dust free alginate impression material was formulated and prepared, comprising an alginate polyvinylpyrrolidone and tetraflouroethylene resins, a mixture of liquid paraffin and dimethylpolysiloxane oil as the dust generation controlling agents and processed diatomaceous earth filler which was obtained from Iranian ore. No dusting was detected during the mixing of the powde...

hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...

background and objective: given the widespread use of paraffin in the treatment of constipation in chil-dren and the possibility of long duration of drug use and the risk of drug leakage, the risk of urinary infection in these patients is considerable. the aim of this study was to determine the association between leakage of paraf-fin and the presence or exacerbation of the urinary infection an...
