PURPOSE To investigate the precipitation process of a mixture of vancomycin and ceftazidime by equilibrium dialysis and determine its subsequent effect on the level of free antibiotics for treatment of endophthalmitis. METHODS Concentrations of vancomycin and ceftazidime in an equilibrium dialysis chamber were measured during the equilibrium process by high-performance liquid chromatography. ...

BACKGROUND There is a need to have a model to study methadone's losses during hemodialysis to provide informed methadone dose recommendations for the practitioner. AIM To build a one-dimensional (1-D), hollow-fiber geometry, ordinary differential equation (ODE) and partial differential equation (PDE) countercurrent hemodialyzer model (ODE/PDE model). METHODOLOGY We conducted a cross-section...

in the management and evaluation of asthma, simple instruments for measurements of peak expiratory flow rate (pefr) are necessary. the aim of this study was to determine normal pefr of the healthy children in babol, iran. this study was randomly done on 1050 students (primary and secondary schools) in babol. mini-wright peak flow meter was used for measurement of pefr. the range of age, weight ...

soil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. this study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. for this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 ml/s) and 2 slope gradients (1.5 and 2...

Although numerous reports have shown that the use of icodextrin solution, as compared with conventional dextrose solutions, provides various clinical benefits, data on the impact of icodextrin solution on mortality and drop-out are sparse. In the present retrospective study, we compared clinical outcomes in a large cohort of patients prescribed either icodextrin or dextrose solution for the lon...

In this work, sweeping gas membrane distillation (SGMD) process was used for concentrating of glucose syrup. The main questions in this work include: is SGMD process practical for concentrating of glucose solution prior the fermentation step in bioethanol process?. and are the commercially available hydrophobic membranes sufficient enough to develop the SGMD process in pilot scale for this issu...

objective: the aim of the present study was to evaluate unstimulated salivary flow rate and oral symptoms in menopausal women. materials and methods: a total of 200 individuals including 100 women in their menopause (case group) and 100 men in the same age range (control group) participated in this analytic descriptive investigation. none of the patients were being treated for any systemic dise...

investigating nozzle’s orifice flow is challenging both experimentally and theoretically. this paper focuses on simulating flow inside diesel injector nozzle via ansys fluent v15. validation is performed with experimental results from winkhofler et al (2001). several important parameters such as mass flow rate, velocity profiles and pressure profiles are used for this validation. results includ...

In this paper, the removal of phenol by using aqueous solution in a low pressure reverse osmosis membrane was investigated. The effect of feed pressure, feed concentration, feed flow rate and feed pH on phenol rejection was investigated. The results showed that feed pH is the most affective parameter on the phenol rejection. Rejection of phenol increased with increasing pH from 2 to 10 under th...
