Usable life of cleaning solutions in a model heat processing unit was studied by evaluation of the nature and quantity of residue remaining on the surface of the equipment after cleaning. Lipoidal residue was recovered from equipment surfaces by ether rinsing. A surface displacement technique was used to quantify the lipoidal material, which was characterized by gas-liquid chromatographic analy...

Two kinds of air duct cleaning methods, mechanical brushing with different brushes and compressed air cleaning, were compared in the laboratory and in newly built buildings. The ducts were contaminated either with test dust or with dust originated from a construction site. The amount of dust on the duct surface was measured with the vacuum test method and estimated visually before and after the...

to evaluate the germination traits and mechanical damage of soybean seed during processing stages, anexperiment was conducted in a factorial experiment based on completely randomized design with 18treatments at mazandaran province (sari) in 2009-10. the experiment factors included different seedprocessing stages (before cleaning, after elevator, after pre cleaning, after cleaning, after drying ...

• Ask the patient to look down. • With one hand, take a new swab and moisten it in the solution. • With the thumb or a finger of the other hand, gently ease the upper eyelid up against the orbital rim (just below the eyebrow), taking care not to put any pressure on the eyeball. • With the swab, gently clean along the upper eyelid margin in one movement from inner to outer canthus (Figure 3). • ...

to amikacin, while 100% of isolates were sensitive to clarithromycin. Clinical resolution of infection may not occur despite appropriate antibiotic therapy. Intravitreal clarithromycin has been reported to be nontoxic to rabbit eyes up to a dose of 1.0 mg; to our knowledge, the use of intravitreal clarithromycin in humans has not been reported. In summary, M chelonae is an uncommon cause of end...

OBJECTIVE To evaluate the use of ear endoscopy in the postoperative management of open mastoidectomy cavities, and to test whether ear endoscopy improves inspection and cleaning compared with ear microscopy. METHODS Prospective study. Thirty-two ears were divided into two groups: group 1, examination and cleaning of mastoid cavities under endoscopic visualization after microscopic standard ea...

42-year-old woman experienced an acute asthma attack, seizures, and unconsciousness immediately after a carpet-cleaning and deodorizing job was conducted in her home. Exposure modeling estimates that she was exposed to approximately 3.4-17 mg/m(3) of sodium tripolyphosphate and more than 14 mg/m(3) volatile organic compounds immediately after the cleaning. I derived two separate exposure models...

We assessed how often bedside stethoscopes in our intensive care unit were cleaned and whether they became colonised with potentially pathogenic bacteria. On two separate days the 12 nurses attending the bedspaces were questioned about frequency of stethoscope cleaning on the unit and the bedside stethoscopes were swabbed before and after cleaning to identify colonising organisms. Twenty-two he...

After manual and machine cleaning of beef intestines, the structure of the intestinal layer was examined. Examination was performed using a histological technique and included 60 intestinal sets of fattened beef (Simmental breed), 10 months of age and with an average slaughter weight of 248.05 kg. Intestines are considered to be edible by-products and therefore are used as natural casings for h...
