The covalent nature of short hydrogen bonds has been under debate for long. Here we show that the crystal orbital Hamilton population (COHP) bonding indicator gives new, complementary evidence of covalent hydrogen···acceptor interactions in the molecular solid state.

a new medium, termed ecol was developed for the detection and enumeration of e. coli. the selective properties of ecol medium for the detection of e.coli from mixed culture in wastewater was tested and compared with conventional coliform media at 37°c and 44°c. results clearly showed that ecol medium was enable to direct confirmation of e.coli to be carried out by the indole reaction. the resul...

background: one of the main and basic pillars of health system promotion is the equitable distribution of health facilities in order to ensure fair access of people in the community to the health services. the goal of this study was to classify the health structural indicators in golestan province using scalogram analysis model. method: a descriptive study was conducted in 2010. data related to...

BACKGROUND Early identification of frailty is important for proactive primary care. Currently, however, there is no consensus on which measure to use. Therefore, we examined whether a Frailty Index (FI), based on ICPC-coded primary care data, and the Groningen Frailty Indicator (GFI) questionnaire identify the same older people as frail. METHODS We conducted a cross-sectional, observational s...

Errors in navigational instruments can significantly affect flight safety. Airspeed is a key piece of navigational data that depends on accurately measured air pressure, which in turn depends on accurately measured air temperature. Instead of measuring the outside air temperature in real time, cockpit instruments are preprogramed with standard air temperature values for different flight altitud...

The GERRI project materializes the Grenelle Environnement’s goals, of which the energy management of a territory is a facet. The aim is to forecast future energy production and consumption, bearing in mind economic and ecological indicators, and using a large number of interactions schemes between the involved parties. The originality of this paper is to present a new approach using the multi-a...

Background and Aims: Helicobacter pylori (H. pylori) is a gram-negative, microaerophilic, spiral-shaped flagellated bacterium that is urease, catalase and oxidase positive. One of its pathogenicity factors is the iceA gene. H. pylori has recently been recognized as a genetic indicator for the development and evolution of duodenal ulcer disease in the East. This study aimed to determine the pres...

Most traditional approaches to anaphora resolution rely heavily on linguistic and domain knowledge. One of the disadvantages of developing a knowledgebased system, however, is that it is a very labourintensive and time-consuming task. This paper presents a robust, knowledge-poor approach to resolving pronouns in technical manuals. This approach is a modification of the practical approach (Mitko...

In this paper, we present a knowledge discovery process applied to hydrological data. To achieve this objective, we combine successive methods to extract knowledge on data collected at stations located along several rivers. Firstly, data is pre processed in order to obtain different spatial proximities. Later, we apply two algorithms to extract spatiotemporal patterns and compare them. Such ele...

Process Improvement has been used for decades as a means to become better and more efficient. Whilst many organizations have used considerable resources for process improvement, investments in process improvement have not always led to changes and improvements expected. One most important aspects of management is to motivate the work force. However, management often fails to deliver. In fact, b...
