Most reservoir fluids contain heavy paraffinic compounds that may precipitate as a solid or solid like material called wax if the fluid is cooled down. Wax precipitation is a phenomenon of considerable importance in oil industry. An increase in aggregation results in enhanced oil viscosity. This however causes significant negative effects on production, transportation and processing of crude oi...

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,...

Paraffin-based fuel has a great potential for several innovative missions, including space tourism, due to its safety, low environmental impact, high performance and cost. Despite the fact that liquefying solid fuels increases regression rate of hybrid rocket motors, incorporating energetic materials into can still improve performance. The objective scope this study is increase characteristics ...

( b ) Six simple cortical cysts, one in serial sections. ( c ) Five small papillary cysts, four of which were studied in serial sections. ( d ) Thirty-seven cystadenomas, of which 13 were single and 6 multiple simple papillary cystadenomas. Fourteen were solid cystadenomas. One papillary and two solid cystadenomas were studied in serial section. ( P ) Three alveolar adenomas, a single paraffin ...

liquid paraffin has been suggested as a good laxative comparing to lactulose as a treatment option in pediatric constipation. this study was performed to compare liquid paraffin with lactulose in pediatric constipation. a total of 247 patients (127 males and 120 females) aged 2-12 years (mean 4.1 ± 2.7 years) with chronic functional constipation were included in an 8 week, randomized, controlle...

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 ...

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...

The objective of the present work is to investigate full phase diagram a binary system composed carbon dioxide and heavy paraffin. An alkane with an odd number was chosen since mixtures paraffins crystallize in orthorhombic structure like pure do. normal-heptadecane taken into consideration for this study as it has melting temperature close ambient condition (295 K). consists measuring both flu...
