The effects of Be additions on the oxidation behavior of ~-NiAl in moist air at 1000°C and borderline alumina-forming y (TiAI) + Laves Ti-Al-Cr based alloys at 800°C and 1000°C in dry and moist air were investigated. The addition of Be to ~-NiAl suppressed the formation of transient alumina, and resulted in the formation of a protective BeAl20 4 spinel phase. In dry air, the addition of Be to t...

to answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. in the present paper, controlled metal based drug (pd(ii) complex) release manner of β‑lactoglobulin (β-lg) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...

A survey of 24 international heart valve banks was conducted to acquire information on heart valve processing techniques used and outcomes achieved. The objective was to provide an overview of heart valve banking activities for tissue bankers, tissue banking associations, and regulatory bodies worldwide. Despite similarities found for basic manufacturing processes, distinct differences in proce...

the release rate of potassium (k) from micaceous minerals plays a significant role in supplying k to plants. the objective of this study was to determine the most appropriate kinetic equation to describe potassium release from micaceous minerals as influenced by organic acids. muscovite and phlogopite were made to react with 0, 500, 2000 and 4000 ?m solutions of oxalic, citric and malic acids f...

It is important for a software company to maximize value creation for a given investment. The purpose of requirements engineering activities is to add business value that is accounted for in terms of return-oninvestment of a software product. This paper provides insight into the release planning processes used in the software industry to create software product value, by presenting three case s...

In the event of a chemical terrorist attack on a transportation hub, post-event remediation and restoration activities necessary to attain unrestricted facility re-use and re-entry could require hours to multiple days. While timeframes are dependent on numerous variables, a primary controlling factor is the level of pre-planning and decision-making completed prior to chemical release. What foll...

T he metabolic syndrome describes the clustering of risk factors for diabetes and cardiovascular disease (1). New Zealand Polynesians of both Maori and Pacific descent have high rates of conponents for the metabolic syndrome: type 2 diabetes (2), obesity (2), hypertension (3), dyslipidemia (4), and coronary heart disease (5,6). There have been no previous reports of the prevalence of the metabo...

There are three categories of blood eosinophilia: reactive (non-clonal), clonal and Idiopathic hypereosinophilic syndrome (HES). The empirical diagnostic criteria of HES are: blood eosinophilia exceeding 1.5xl09/l for more than six consecutive months; absence of an underlying cause of hypereosinophilia despite extensive diagnostic evaluation and organ damage or dysfunction as a result of local ...
