Heavily polluted sediment is becoming an important part of water pollution, and this situation is particularly acute in developing countries. Sediment has gradually changed from being the pollution adsorbent to the release source and has influenced the water environment and public health. In this study, we evaluated the pollutant distribution in sediment in a heavily polluted river and agitated...

It is an already established fact through the investigations by Thomson (1), Saenz (2), Rist (3), Freund (4), Hensel (5), etc that the inoculation of a paraffin oil suspension of heat-killed tubercle bacilli produces in experimental animals a state of hypersensitivity much more intense and lasting than that given by the same amount of the killed bacilli in saline solution. We have confirmed thi...

Tabling is a technique of resolution that overcomes some limitations of traditional Prolog systems in dealing with recursion and redundant sub-computations. We can distinguish two main categories of tabling mechanisms: suspension-based tabling and linear tabling. In suspension-based tabling, a tabled evaluation can be seen as a sequence of sub-computations that suspend and later resume. Linear ...

The flocculation performance of three poly(acrylic acid) (PAA) samples (Mw = 9 10, 2.5 10 and 1 10 g/mol) has been investigated. Colloidal alumina particles were used as a model system and tests were performed at pH 5. Using a singlecomponent polyacid, it was found that the optimum dosage required to achieve supernatant clarity was similar between the 9 10 g/mol PAA (23 ppm) and 2.5 10 g/mol PA...

PURPOSE The main objective of this study is to determine the anti-inflammatory effect of topical amniotic membrane (AM) suspension on corneal alkali burn compared to topical serum eyedrops. METHODS Thirty eyes from 30 Sprague-Dawley male rats were used. After alkali injuries using 1 N NaOH, the control group (n = 10) received topical PBS four times a day for 2 days. The first study group rece...

the photocatalytic activity of nano-tio2 has been used in inactivation of microorganisms, mainly in the form of suspension in a liquid or partially in an immobilized system. using advanced oxidation processasa new approach has been used in the purification of water and wastewater. in this research, the systems of suspended (0.1 g/l) and immobilized nano-tio2 in the cement bed (0.1-2%) under a 1...

Suspension feeders rely on filter structures of a variety of forms to capture food particles. Much effort has been devoted to examining the operation of such filters, but mechanistic evaluations have generally represented filter elements with artificially stiff cylinders. We extended this previous work to investigate how bending affects the function of flexible cylindrical filter elements. Scal...
