The use of computer applications can be a frustrating experience. This study replicates previous studies of the amount of time users – involuntarily – spend trying to diagnose and recover from problems they encounter while using computer applications such as web browsers, email, and text processing. In the present study, 21 users self-reported their frustrating experiences during an average of ...

The paper is a short survey of recent developments in the area of word maps evaluated on groups and algebras. It is aimed to pose questions relevant to Kac–Moody theory.

Photosynthesis produced by far-red light (about 700 mmicro) is reversibly inhibited in some algae by extreme-red light ( approximately 750 mmicro).

The photosystem I reaction center complex, the P-700-chlorophyll a-protein, has been isolated from the photosynthetic membranes of two marine dinoflagellates, Gonyaulax polyedra and Glenodinium sp., by detergent solubilization with Triton X-100. The complexes isolated from the two species were indistinguishable, exhibiting identical absorption properties (400-700 nm) at both room (300 K) and lo...

We developed MicroGen, a multi-database Web based system for managing all the information characterizing spotted microarray experiments. It supports information gathering and storing according to the Minimum Information About Microarray Experiments (MIAME) standard. It also allows easy sharing of information and data among all multidisciplinary actors involved in spotted microarray experiments.

OBJECTIVES To analyse the total number of newspaper articles citing the four leading general medical journals and to describe national citation patterns. DESIGN Quantitative content analysis. SETTING/SAMPLE Full text of 22 general newspapers in 14 countries over the period 2008-2015, collected from LexisNexis. The 14 countries have been categorised into four regions: the USA, the UK, Wester...

This paper uses a short 'Christmas fairy-story for oncologists' sent by Christopher Andrewes with a 1935 letter to Peyton Rous as the centrepiece of a reflection on the state of knowledge and speculation about the viral aetiology of cancer in the 1930s. Although explicitly not intended for public circulation at the time, the fairy-story merits publication for its significance in the history of ...

Compelling evidence exists that conflict and communication problems occur between nursing home staff and family members of residents. However, few interventions have been documented that simultaneously address the needs of both groups. The Partners in Caregiving program was created to train staff and family members in communication techniques and conflict resolution skills. Through a joint meet...
