INTRODUCTION This study compared (1) the accuracy of three different electronic apex locators (EALs) in detecting the apical foramen ex vivo under clinical conditions; (2) the accuracy of digital radiography and EALs in determining the working length (WL) with visible control under a microscope; and (3) the precision of #10, #15, and #20 K-files in electronic measurements. METHODS The length ...

Phosphorus (P) is an essential element for plant growth. Crop production of common bean (Phaseolus vulgaris), the most important legume for human consumption, is often limited by low P in the soil. Functional genomics were used to investigate global gene expression and metabolic responses of bean plants grown under P-deficient and P-sufficient conditions. P-deficient plants showed enhanced root...

E. longifolia is attracting interest due to its pharmacological properties and pro-vitality effects. In this study, an online SPE-LC approach using polystyrene divinyl benzene (PSDVB) and C18 columns was developed in obtaining chromatographic fingerprints of E. longifolia. E. longifolia root samples were extracted using pressurized liquid extraction (PLE) technique prior to online SPE-LC. The e...

Recently, the resources of medicinal plants have been exhausting. The root of Angelica acutiloba is one of the most important ingredients in Japanese Kampo medicine for the treatment of gynecological diseases. In our search for alternative medicinal plant resources of the root of A. acutiloba, we found that its aerial part has the anti-inflammatory potency as well as the root. Phytochemical inv...

with the emergence of the theory of control in linguistics and the introduction of pro as one of the empty categories in government and binding, one can find the investigation of the interpretive properties of pro in the generative agenda. within these studies, especially within the minimalist tradition, some new properties were added to the list while others lost their values. as such, a new p...

kentucky bluegrass (poa pratensis l.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. the objective of this study was to investigate whether prohexadione-calcium (pro-ca) may play a role in promoting ...

It has often been observed that children go through a stage in their language development where they omit subjects. This occurs in children learning both pro-drop and non-pro-drop languages and poses questions for a traditional parameter-based theory of language acquisition. In this paper I give an overview of some of the existing accounts of this phenomenon, considering the patterns that emerg...

In response to the trend of efficient global economy, constructing a global logistic model has garnered much attention from the industry. Location selection is an important issue for those international companies that are interested in building a global logistic management system. This paper will be based on six different strategic roles of overseas sites proposed by Ferdows with focus on site ...

We consider the binary paint shop problem (PPW(2,1)). We describe an approach to solve PPW(2,1). This approach is based on constructing a logical model for PPW(2,1). Mathematics Subject Classification: 68T20
