Pour Point Depressant (PPD) Testing are used extensively to modify the crystallinity of hard waxes and reduce natural pour point crude. The best PPD chemical dosage for crude oil treatment will be chosen based on laboratory test results to: Reduce oil; viscosity Improve rheological properties wax deposition rate pipeline restart pressure. performance evaluation PPD, proposed use at X Oil Field ...

The purpose of this study was to clarify the cytopathological features of well-differentiated tumors of uncertain malignant potential (WDT-UMP), a possible borderline lesion of thyroid follicular cell tumor. We analysed the cytopathological findings of fine needle aspiration (FNA) smears from 6 cases histologically diagnosed as WDT-UMP. WDT-UMP, benign and malignant lesions were compared retros...

1:)8ssage of AMDUCA and its implementation by the r FDA-Center for Veterinary Medicine has allowed food animal veterinarians to use drugs legally in an exttalabel manner as long as an appropriately extended withdrawal time (WDT) is followed. Providing these extended WDT for specific drug classes has been the main focus for the FARAD Digest series in the ]AVMA.1 But, what is the basis of these e...

PURPOSE To evaluate variations in choroidal thickness (CT) during the water drinking test (WDT) in emmetropic eyes (EE) and highly myopic eyes (ME) using spectral-domain optical coherence tomography (SD-OCT). METHODS Clinical trial performed at a tertiary care hospital comprising 30 randomly selected eyes. The WDT and SD-OCT macular scans were performed 10 and 45 min after water ingestion in ...

OBJECTIVES To retrospectively collect data on patients with burn injury due to hot depilatory wax. To investigate the effect of varying microwave output power on wax temperature. To determine whether instructions provided by manufacturers allow safe domestic use. METHODS Data from the RAH burns database was collected for patients with wax-induced burns between January 1991 and January 2010. W...

PURPOSE We investigated the correlation between 24-hour IOP in the habitual (sitting during day and supine during night) position (H24h-IOP) and IOP after a postural-change test (PCT-IOP) and a water-drinking test (WDT-IOP). We also investigated ocular and systemic factors related with them in patients with normal tension glaucoma (NTG). METHODS Japanese NTG patients underwent H24h-IOP, PCT-I...

OBJECTIVE To evaluate changes in peripapillary and macular choroidal thickness and volume after the water-drinking test (WDT) using swept-source optical coherence tomography (SS OCT). DESIGN Prospective, cross-sectional, observational study. PARTICIPANTS Fifty-six eyes of 28 healthy volunteers. METHODS Participants underwent a 3-dimensional optic disc and macula scanning protocol with a p...

The influences of several operating factors on the viscosity of the Isfahan refinery waxy crude oil sample are studied through conducting some rheological shear rotational tests. The Taguchi design method is adopted to determine the impact of factors such as shear rate, temperature, cooling rate, wax content, and asphaltene content on the viscosity of the waxy crude oil. The results show that t...
