In relational databases, it is essential to know all minimal keys since the concept of database normaliza-tion based on and functional dependencies a relation schema. Existing algorithms for determining keysor computing closure arbitrary sets attributes are generally time-consuming. this paper we present anefficient algorithm, called KeyFinder, solving key-finding problem. We also propose more...

This study aimed to assess the effectiveness of bacterial cellulose nanocrystals (BCNCs)-gelatin (GelA)/cinnamon essential oil (CEO) emulsion coatings containing various CEO concentrations (1200, 1800, and 2400 μL/L) in retarding ripening senescence ‘Red Delicious’ apples during cold storage (60 days at 4 °C). Coatings decreased weight loss (WL) (~3.6%), as compared uncoated fruit (~4.8%). A di...

BACKGROUND The potential of Origanum syriacum L. to become a cultivated crop in Lebanon rather than being harvested from the wild was investigated at the production, postharvest and economic levels. Three irrigation schemes were tested on growth parameters of cultivated oregano plants. In order to identify the most quality-preserving drying technique, air-, oven (30 °C)- and freeze-dried oregan...

AIMS This study was designed to examine the decision making processes that nurses use when assessing and managing sedation for a critically ill patient, specifically the attributes and concepts used to determine sedation needs and the influence of a sedation guideline on the decision making processes.

In recent years, the attention on essential oils (EOs) as natural additives of food products have been rapidly growing due to the extended health risk of synthetic preservatives. Artificial additives can minimize food spoilage, though the current generation is very health-conscious and believes in natural preservatives rather than the synthetic ones owing to their potential toxicity and other c...

The correlation between the performance of attributes and the overallsatisfaction such as they are perceived by the customers is often used tocalculate the importance of attributes in the crisp case. Recently, the methodwas extended, based on the standard Zadeh extension principle, to the fuzzycase, taking into account the specificity of the human thinking. Thedifficulties of calculation are im...
