Filtration products utilizing Nylon 6,6 membrane technology have demonstrated effectiveness in reducing microbridge defects in DUV photoresist patterning. The effects of fluid flow characteristics on defect reduction using a point-of-use Nylon 6,6 filtration product are explored. Lower filtration pressure and longer contact time were found to enhance the removal of gel-like microbridge defect p...

The prevalence of colloid deposition at grain-to-grain contacts in two porous media (spherical glass beads and angular quartz sand, 710-850 microm) was examined using X-ray microtomography (XMT) under conditions where the colloid-grain surface interaction was solely attractive (lacking an energy barrier to deposition), and under fluid velocity conditions representative of engineered filtration ...

MacConkey-inositol-carbenicillin agar has successfully been used as a primary selective medium for Klebsiella enumeration. With pure cultures, nearly 100% recovery of Klebsiella was observed by membrane filtration. With environmental samples using membrane filtration, 95% of typical pink- to red-colored colonies were verified as Klebsiella, as opposed to only 1% of yellow background colonies. R...

Computer games and interactive entertainment have gained much attention recently in the domain of digital media. They are now being applied or used in many areas such as entertainment, education, training, and art. Today, the computer games and interactive entertainment market is highly competitive. In this special issue, all the submissions are invited papers which are extended from original c...

the main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of methocel® k15, ethocel® standard 7fp premium, eudragit ® rs100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. risperidone floating tablets were formulated by wet granulati...

An oral sustained-release floating tablet formulation of metformin HCl was designed and developed. Effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and HPMC-PEO polymer combination, respectively. Tablet composition was optimized by response surface methodology (RSM). Seventeen (17) trial formulations were analyzed according to Box-Behnken desi...

Methods and Results-—We recruited 1282 CKD patients admitted to our hospital division. Patients were divided into 4 groups: INH; isolated daytime hypertension; day–night sustained; and ambulatory normotension. Multiple linear regression analyses were used to evaluate the correlation between INH and renal/cardiovascular parameters. A total of 262 (20.44%) CKD patients had isolated nocturnal hype...

We describe methods for studying the binding of Al by protein in serum: ultrafiltration, gel filtration, and immuno-affinity chromatography. For ultrafiltration we used an Amicon YM10 cellophane membrane with a nominal cutoff of 10 000 Da to separate ultrafiltrable and non-ultrafiltrable Al. For gel filtration we used Sephacryl S-300, and for immuno-affinity chromatography we used anti-transfer...

BACKGROUND Isolated nocturnal hypertension (INH) has been studied among the general population and hypertensive patients. However, little insight is available on the prevalence of INH and its role in target-organ damage among patients with chronic kidney disease (CKD). METHODS AND RESULTS We recruited 1282 CKD patients admitted to our hospital division. Patients were divided into 4 groups: IN...

At this article will be created a software written in visual basic for efficiency and penetration calculation in a fibrous filter medium for given values of particles diameter that are retained in the filter. Initially, will become report of mathematical models of air filtration in fibrous filters media and then will develop the code and the graphical interface of application, that are the base...
