The absorption characteristics of porous absorbers in combination with perforated facings was investigated. The effect of the hole size, hole pattern and open area ratio were examined. The absorption coefficients for an absorber of uniform cross-section were compared to those for an absorber with a tapered cross-section for various volumes of absorbent and different perforated facings.
In this short communication we report a quick, cost-free method of purification of DNA fragments from agarose gel. Unlike those procedures that involve commercial kits, this method uses glass wool or absorbent cotton to filter agarose gel during a quick spinning-down of DNA, thus significantly simplifying the routine practice of many molecular biologists and decreasing the cost.
This article describes a pilot study to evaluate washable (or reusable) absorbent garments for adults with moderate to heavy urinary incontinence. The article will describe: The study process; How the individual products performed and how the washable and disposable products compared; How nurses can enable their patients to use washable products appropriately.
The crossed compound parabolic concentrator (CCPC) is one of the most efficient non-imaging solar concentrators used as a stationary solar concentrator or as a second stage solar concentrator. In this study, the CCPC is modified to demonstrate for the first time a new generation of solar concentrators working simultaneously as an electricity generator and thermal collector. The CCPC is designed...
BACKGROUND Few data exist on compound A during sevoflurane anesthesia when using closed-circuit conditions and sodalime with modern computer-controlled liquid injection. METHODS A PhysioFlex apparatus (Dräger, Lübeck, Germany) was connected to an artificial test lung (inflow approximately 160 ml/min carbon dioxide, outflow approximately 200 ml/min, simulating oxygen consumption). Ventilation ...
Gastrointestinal obstruction caused by a radiolucent foreign body in a green iguana (Iguana Iguana).
This report describes an intestinal obstruction in a green iguana (Iguana iguana). The patient was presented with vomiting and subtle signs of abdominal pain. Radiographs and ultrasound imaging did not reveal any abnormalities. A coeliotomy was performed and a 30-cm piece of absorbent cotton was removed surgically from the large intestine.
background : textile wastewater is the most important pollutant of the environment. navy blue (nb) ce-rn is an important chemical dye widely used in the textile industry. the present study aimed to investigate the removal of nb textile dyes from aqueous solutions using magnetic iron oxide absorbents. methods: in this study, a sample of synthetic wastewater with nb concentration of 50 mg/l was u...
Moisture absorbency is one of the most important characteristics of rodent beddings for controlling bacterial growth and ammonia production. However, bedding manufacturers rarely provide information on the absorbencies of available materials, and even when they do, absorption values are usually expressed per unit mass of bedding. Since beddings are usually placed into cages to reach a required ...
Let D be a digraph, V (D) and A(D) will denote the sets of vertices and arcs of D, respectively. A (k, l)-kernel N of D is a k-independent set of vertices (if u, v ∈ N then d(u, v), d(v, u) ≥ k) and l-absorbent (if u ∈ V (D) \N then exists v ∈ N such that d(u, v) ≤ l). A k-kernel is a (k, k − 1)-kernel. We propose an extension of the definition of (k, l)-kernel to (arc-)weighted digraphs, verif...
