The aim of the present work was to develop a programmed drug delivery system which would be able to release the drug after 6 h of lag time by use of hydrophilic polymers. The capsule body was made impermeable by use of formaldehyde vapor treatment, while the cap was untreated. The capsule was filled with two layered tablets (tablet-in-capsule), followed by a sodium bicarbonate:citric acid mixtu...

The combination of PCR amplification of 16S rRNA genes with denaturing gradient gel electrophoresis (DGGE) analysis was used to reveal the compositions and dynamics of bacterial communities in a sewage treatment plant with two systems, i.e., an anoxic-anaerobic-aerobic system (inverted A20) and an anaerobic-anoxic-aerobic one (conventional A20) over a period from February to July 2009, during w...

INTRODUCTION There are a myriad of treatment options available for patients suffering with the increasingly prevalent condition of stress urinary incontinence (SUI). The minimally invasive nature of periurethral bulking agents makes them an attractive proposition in the correctly selected patient. There is, however, limited data available on the medium to long term safety and efficacy of this p...

• Generated material constants from test and literature data that capture the proper physics (pressure dependence, strain rate, strength of failed material, bulking) Performed hypervelocity impacts measured crater dimensions momentum enhancement. Checked with models provide right computations shape Abstrac t Two NASA missions will be launched in 2022 have spun renewed interest impact rocks meta...

Bulking agent injected submucosally is an alternative effective treatment for faecal incontinence in elderly patients who fail conservative measures. Since most elderly patients are on antiplatelet therapy and are sometimes unaware of their medication, this can lead to serious complications.

Activated sludge is a complex ecosystem constituted mainly of bacteria and protozoa. Filamentous bulking, a phenomenon when the filamentous organisms dominate the activated sludge is still a widespread problem in the operation of activated sludge processes. Image analysis offers promising perspectives for early detection of filamentous bulking because the morphology parameters of the activated ...

Biodrying consists of reducing moisture by using the heat from aerobic bio-degradation. The parameters that control the process are: aeration, temperature during the process, initial moisture of biowaste, and temperature and relative humidity of the input air. Lawn mowing and garden waste from the gardens of the University Jaume I, Castellón (Spain) were used as a substrate. Biodrying was perfo...

Activated sludge systems are biological processes greatly used in wastewater treatment plants (WWTPs). These systems are composed of an aerated tank where the biochemical phase occurs and a settler where the physical phase takes place. Solid-liquid separation is one of the most critical steps in activated sludge processes. This stage presents three main objectives: sludge thickening, effluent c...

alcohol production from molasses can lead to large amounts of wastewater that cause serious environmental concern. it is characterized with extremely high organic loading rate, high turbidity and dark brown color .composting this kind of wastewater is a biothermal aerobic process that during composting heat generated by the composition of the organic material reduces the moisture content of the...

Introduction: Dissatisfaction of penile girth is an increasing phenomenon. We have noticed an increased number of patients presenting with complications following injection of bulking agents into the penis. In both the medical and non-medical setting, commonly injected bulking agents include paraffin, petroleum jelly, mineral oil, cod liver oil, metallic mercury, and petroleum jelly. Case repor...
