False mildew is a serious disease of safflower crops in the Yaqui Valley, Mexico, and is caused by infection with a fungus belonging to the genus Ramularia. In the present study, a fungus isolated from leaf lesions was grown under different growth conditions in order to study its mycelial growth and spore production, determining that the solid medium of Septoria tritici at 18 °C of incubation a...

Introduction THIS PAPER seeks to demonstrate how case study research (CSR) was used for rigorous enquiry in a study of work placements used by further education (FE) students on a health studies programme in the UK. These students use similar placements to higher education (HE) students on pre-registration nursing programmes in the UK. Consequently, the study offered insight into the student ex...

Medicaid visits or of all private insurance visits. A related goal of the present research was to examine whether the percentage of all emergency department visits by individuals with no health insurance between the ages of 0 and 64 years was greater than that of all individuals between the ages of 0 and 64 years. To that end, we used data from three nationally representative surveys to estimat...
متن کامل3,9′-Bi(9H-fluorene)
THE TITLE COMPOUND [SYSTEMATIC NAME: 9-(9H-fluoren-3-yl)-9H-fluorene], C(26)H(18), was obtained unintentionally as the product of the synthesis of a compound based on fluorene-thio-phene units. The two fluorene rings are connected through C atoms in the 3- and 9'-positions, and the dihedral angle between the mean planes of the two fluorene units is 78.57 (6)°.
متن کاملNuclear magnetic ordening in fluorene
The present paper considers the possibility to obtain a magnetic ordering of the proton spins in molecular crystals of fluorene using dynamic nuclear polarization (DNP) followed by adibatic demagnetization in the rotating frame (ADRF). It is found that such an ordering is most easily reached for T < 0 and 80 II c-axis. Then a polarization of only 26% needs to be reached by DNP in order to obtai...
