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...

Paraffin phase change materials (PCMs) exhibit great potential in battery thermal management (BTM); nevertheless, their application has been hampered by the handicap of low conductivity, leakage, and volume expansion during transition. In this work, ternary composite PCMs formed paraffin, expanded graphite (EG), low-density polyethylene (LDPE) were developed for BTM. The structure properties ch...

We use acetylated cellulose nanofibrils (AcCNF) to stabilize transient emulsions with paraffin that becomes shape-stable and encapsulated phase change material (PCM) upon cooling. Rheology measurements confirm the gel behavior colloidal stability of solid suspensions. study effect nanofiber content on PCM leakage melting compare results those from unmodified CNF. The nanostructured promotes tra...

The wax leakage from shape-stabilized phase change materials (SSPCMs) is a limitation because it reduces their functionality. In this work, an enhancement of the compositional stability SSPCMs formed by high-density polyethylene (HDPE) and paraffin blends through lamination aluminum (Al) foil was studied. materials’ thermal conductivity enhanced adding expanded graphite (EG). simplest method re...

170 patients admitted to shariaty hospital pulmonary ward were studied for pulmonary nocardiosis during 17 months (aug 1990-jan 1992). paraffin baiting was used and nocardia asteroides isolated in five cases from sputum, pleural fluid and bronchial washing. the technique used in this study inhibits growth of other organism and yeast and is reliable, simple and cheap for isolation of nocardia fr...

Buildings are the major energy users and by 2035, they will be fourth largest source of greenhouse gas emissions. Phase change materials (PCMs) applied to shift peak-load off-peak-load, positively effecting efficiency building. In this paper, an experimental embedding PCM (Paraffin) with bricks in conventional wall layers is carried out. The effect on thermal diffusion inner surface studied. Ca...

Melamine formaldehyde microcapsules containing paraffin wax as phase change material (PCM) were synthesized. Free space was generated in-situ inside microcapsules. These characterized by FTIR Spectrophotometer, Scanning electron microscope (SEM), Differential colorimeter (DSC), and optical microscope. It confirmed that PCM successfully encapsulated the shell material. Encapsulated showed good p...

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,...

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...
