Alfa Chemistry is able to design and conduct in vivo and in vitro pharmacokinetic (PK) tests for different projects, providing complete pharmacokinetic evaluation and optimization services, including: biological target validation, early physical and chemical properties screening, metabolite identification (metid), in vitro studies, in vivo studies, etc. ...
A barrier to achieving these benefits, however, has been the length of time required to test biochemical oxygen demand (BOD) and chemical oxygen demand (COD) – the most relevant wastewater organics testing parameters. Real Tech recently introduced a new series of portable testing meters to its comprehensive line of water quality monitoring ...
Data presented at AAIC demonstrates oral lead product candidate OLX-07010 reduces tau self-association and insoluble tau aggregates Oligomerix to begin clinical testing of OLX-07010 in 2Q22 Oligomerix, Inc., a privately held company pioneering the development of small molecule therapeutics targeting tau for rare neurodegenerative and Alzheimer’s ...
Eagle International offers two of the best options on the market for removing sidewalls from end-of-life tires: the Sidewall Cutter and the Super Slicer. But why would you want to remove the sidewalls? What would you do with the leftover tread? Both the sidewall and the tread can be reused in a variety of applications. Once a tire hits the end of its life, what do you do with it? Once there is ...
ASTM International Committee C09 on Concrete and Concrete Aggregates has recently approved a new test method for evaluating the suitability of fine aggregates and other fillers for use in concrete. The standard provides a rapid test for laboratory and field use to determine the amount of methylene blue adsorbed by a specimen of ...
Shimadzu Scientific Instruments has introduced an Aggregates Sizer Aggregation Analysis System, the first commercially available tool to provide real-time quantitative evaluation of 100nm to 10μm sub-visible particle (SVP) aggregates. ...
This practice is intended for the preparation of standard specimens of soil-asphalt mixtures suitable for tests of Test Methods , D1560, D1561, D4123, and other tests using specimens of the above dimensions. ...
Terms relating to constituents of concrete aggregates are defined in Descriptive Nomenclature C294. Terms relating to constituents of aggregates for radiation-shielding concrete are defined in Descriptive Nomenclature C638. 1.3 Related terminology for hydraulic cement is included in Terminology C219. ...
This specification defines the minimum requirements for inspection agency personnel or testing agency laboratory personnel, or both, and the minimum technical requirements for equipment and procedures utilized in the testing and inspection of construction and materials used in construction. ...
The material shall be subjected to the following test methods: compression test specimens; compression tests; yield; unit weight; air content; slump; and temperature. ...
This specification covers the standards for the quality and grading of crushed stone, crushed slag, and water-worn gravel intended for use as coarse mineral aggregate on built-up roofs. The crushed stone and gravel shall be hard, durable, opaque, and free of foreign substances. ...
Note 1—The fresh density of lightweight aggregate concrete is a function of mixture proportions, air content, water demand, and the specific density and moisture content of the lightweight aggregate. ...
Scope 1.1 This test method measures the quantity of aggregate needed to provide an opaque layer under laboratory conditions. Aggregate size Numbers 1 through 8, as listed in Classification D448, may be tested. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. ...
This specification covers hollow and solid concrete masonry units made from hydraulic cement, water, and mineral aggregates with or without the inclusion of other materials. There are three classes of concrete masonry units: normal weight, medium weight, and lightweight. ...
