probable use of chemical and biochemical detergents to wash polysulphone membranes using in milk ultrafiltration needs a multidisciplinary investigation. by increasing use of these membranes in food processing, washing and recovery of initial permeate flux, in order to use for a longer time from this technology, has much importance. in this research, influence of chemical detergents including e...

this paper presents a sensorless system drive on primary flux oriented control (pfoc) and secondary flux oriented control (sfoc) for the linear induction motor (lim) with taking into account end effect. extended kalman filter (ekf) is applied to estimate lim speed by measuring motor voltages and currents. in order to achieve desirable dynamic and robustness motor performance instead of traditio...

Introduction: Extra-pulmonary tuberculosis (EPTB) arising in extra-oral region in head and neck are rare, and when swellings arise from other sites such as infraorbital region, cheek, etc, tuberculosis is not usually considered for the differential diagnosis (DD) and often the diagnosis is missed and appropriate treatment is delayed. Case Report: We report a rare entity of pri...

Wetting of the membrane to displace air or conditioning liquids is important exploit complex porosity a filtration membrane. This study reveals details wetting in multibore membrane-based modules. Using magnetic resonance imaging (MRI), we quantify fluid distribution patterns during initial dead-end permeation mode. The spatio-temporal evolution aqueous copper sulfate solution fibers was invest...

BACKGROUND Colorectal cancer is the third commonest cause of cancer death in UK. It commonly metastasises to the liver but rarely to small bones. CASE PRESENTATION We describe a case of a patient with adenocarcinoma of the descending colon who presented preoperatively with a right supraclavicular swelling. Subsequent imaging and cytology of the lesion revealed this to be a metastasis to the r...

The most common benign salivary gland tumor is pleomorphic adenoma. They can attain giant proportions and weigh several kilograms. They can cause facial disfigurement and, if untreated, could lead malignant transformation. This image depicts a 7.5 kg pleomorphic adenoma of right submandibular gland with malignant change in a 55-year-old male.

DOI: 10.1590/S1679-45082014AI2606 A 22-day-old male infant, the first child of nonconsanguineous parents, who was delivered from a followed-up and normal pregnancy, and without alterations in analytical and echographic evaluation. He was born by cesarean section at 39 weeks, because the labor failed to progress, with Apgar score of 9 at 1 minute and of 10 at 5 minute, weighting 3,240g at birth ...
