This specification covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Forging or shaping operations shall be performed by hammering, pressing, piercing, extrudin…
With recently announced measures in the USA and the European Union (EU) to improve vehicle efficiency and reduce CO 2 emissions for passenger cars, respectively, weight reduction promises to become even more imperative for the automotive industry, according to Milliken Chemical. To help automotive manufacturers and su…
Scope1.1 This specification establishes requirements for brass rod (round, hexagonal, and octagonal), bar (rectangular and square), and shapes of UNS Alloys C21000, C22000, C23000, C24000, C26000, C26800, C27000, C27400, and C27450. 1.2 Units—The values s
“协同效应”在本文中是指两方或者多方, 发生或者促进不同于任何相应单方所能够发生或者促进的化学反应(包括反应机制和生成不同的产物). 协同效应可能(1)使得原来不能够发生的反应顺利进行或者使得原来能够发生但是速度很慢的反应加速进行, (2)提高反应的选择性(包括化学选择性、区域选择性和立体选择性), 使得原来生成混合物的反应只生成一种产物, (3)改变反应的方向, 高选择性生成另一种产物. 能够实现协同效应的体系可以多种多样, 包括如双或者多金属有机化合物, 双或者多金属配合物, 以及具有Lewis酸性的金属(有机)化合物与过渡金属的协同作用. 近十年来, 作者提出并坚持以“协同效应”为指导思想的科学研究思路, 在双金属有机合成试…
These test methods cover procedures for the sampling and chemical analysis of inorganic alkaline detergents. These detergents include caustic soda, soda ash, modified soda (sequicarbonate type), sodium bicarbonate, sodium metasilicate, trisodium phosphate, tetrasodium pyrophosphate, borax, and sodium triphosphate. Dif…
This specification covers spray-formed seamless ferritic/austenitic stainless steel pipe intended for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. The steel shall be…
This specification covers carbon and alloy steel pipe, electric-fusion-welded with filler metal added, fabricated from pressure-vessel-quality plate of several analyses and strength levels and suitable for high-pressure service at high temperatures. Heat treatment may or may not be required to attain the desired mecha…
Significance and UseA major factor affecting the long term performance of insulating materials is thermal degradation. Other factors, such as moisture and vibration, may cause failures after the material has been weakened by thermal degradation. An elec
In this paper will be present and analyzed the data for mineralogical composition of the weathering crust of Groot deposit. This deposit, in general, is combination of silicate nickel and redeposited nickel iron. There are several metals in the mineral association of the Groot deposit, and nickel is present in the min…
With costs rising again for key raw materials in recent months, regular price increases also are becoming the norm for a wide range of polymer additives including pigments, plasticizers and modifiers. Producers are also citing rising energy and freight costs and the need to speed up the recovery of such elevated opera…
Αντικείμενο της παρούσας διατριβής είναι η ανάπτυξη συστοιχίας αισθητήρων χωρητικότητας για την ανίχνευση χημικών και βιολογικών ενώσεων. Η συστοιχία αποτελείται από 16 γραμμές και 16 στήλες, έτσι περιλαμβάνει έως και 256 αισθητήρες. Κάθε αισθητήρας χρησιμοποιεί μια υπέρλεπτη μεμβράνη πυριτίου επιλεκτικά επικαλυμμένη…
UK-based ACAL Energy has announced the successful startup of a kW-scale fuel cell system using its patented FlowCath® liquid cathode technology. The hydrogen-fueled ‘short stack' unit has already achieved a continuous power output of over 600 W, and is expected to deliver more than 1.5 kW with the full stack by the fa…

International Theory welcomes scholarship that uses evidence from the real world to advance theoretical arguments.However, it is intended as a forum where scholars can develop theoretical arguments in depth without an expectation of extensive empirical analysis.
Abstract This chapter focuses on phase transitions, discussing latent heat and deriving the Clausius-Clapeyron equation. It discusses the criteria for stability and metastability, and derives the Gibbs phase rule. It introduces colligative properties and classifies the different types of phase transition.
Current research aims to find effective means of creating biomimetic vascular systems for polymeric composite materials. One method for autonomic growth of branching structures is explored in this thesis. Motivation is taken from electrical treeing and viscous fingering phenomena. Applying these basic principles, Saff…
A Scandinavian collaboration has made significant progress in a project to develop a fuel reformer/fuel cell auxiliary power unit (APU) suitable for use in heavy good vehicles (HGVs) and forklift trucks, using hydrogen reformed from diesel. The system also incorporates the capability of subzero temperature operation.
Honeywell Specialty Materials reports that its Rheochem® line of high-performance lubricants (HPLs) has received certifications from independent, not-for-profit organization NSF International and the Plastics Pipe Institute for use in PVC water pipe formulations. The certifications indicate that the HPLs are safe and…
Evaluation of the radiological protection quantity E requires determining the dose deposited in different organs and tissues. This is why monitoring in exposed workplaces is ensured by dosimeters that are worn on the trunk and calibrated to measure the personal dose equivalent Hp(10) as an estimator of the effective d…
The smectite-illite (SI) reaction is a ubiquitous process in siliciclastic sedimentary environments. For the last 4 decades the importance of to illite (S-I) reaction was described in research papers and reports, as the degree of the (S-I) reaction, termed smectite illitization, is linked to the exploration of hydroca…
