The Evolution of TPC Benchmarks: Why TPC-A and TPC-B are Obsolete

TPC benchmarks provide the de facto industry standard for measuring transaction processing performance. This paper argues that TPC-A and TPC-B have served their purpose and are effectively obsolete. Several problems with the benchmarks are described including flaws in the pricing model, the impact of terminals in the priceperformance metric, use of client-server configurations, and the use of s...

Free radical scavenging capacity and antioxidant activity of methanolic and ethanolic extracts of plum (Prunus domestica L.) in both fresh and dried samples

Objectives: Consumption of fruits, such as plums and prunes, is useful in treating blood circulation disorder, measles, digestive disorder, and prevention of cancer, diabetes, and obesity. The paper presents a description of antioxidant and antiradical capacity of plum (Prunus domestica L.) in both fresh and dried samples. Materials and Methods: Samples were mixed with methanol and ethanol (as ...

Changes in Total Phenol and Some Enzymatic and Non-Enzymatic Antioxidant Activities of Rose-scented Geranium (Pelargonium graveolens) in Response to Exogenous Ascorbic Acid and Iron Nutrition

Strong antioxidant activity of Pelargonium graveolens is well known. The question addressed in this study was whether different concentrations of exogenous ascorbic acid (AsA) and iron (Fe) were able to influence antioxidant activity and total phenol content (TPC) of geranium. Thus, three levels of Fe (0, 20 and 40 µM) and three levels of AsA (0, 1 and 2 mM) in nutrient solution were c...

Effect of Roasting Process on Total Phenolic Compounds and γ-tocopherol Contents of Iranian Sesame Seeds (Sesamum indicum)

Sesame (Sesamum indicum L.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. Some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. The purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (TPC) of sesame seeds when roas...
