The Science of the total environment

Gómez R, Asencio AD, Picón JM, Del Campo R, Arce MI, Del Mar Sánchez-Montoya M, Suárez ML, Vidal-Abarca MR.
PMID: 26410723
Sci Total Environ. 2016 Jan 15;541:491-501. doi: 10.1016/j.scitotenv.2015.09.040. Epub 2015 Sep 26.

Saline streams occur naturally and they are distributed worldwide, particularly in arid and semiarid regions, but human activities have also increased their number in many parts of the world. Little attention has been paid to assess increasing salt effects...

Introducing the objective structured clinical examination to a general practice residency programme: results of a French pilot study.

Med Teach. 2001 Jul;23(4):383-388. doi: 10.1080/01421590120031048.

OSCE for evaluating clinical competence still remains limited in France. This study presents the results of the first experimental use of an OSCE as a formative assessment of French general practice trainees. Fifty trainees rotated through a circuit of...

Should surgeons as well as radiologists report mammograms in symptomatic patients?.

Breast (Edinburgh, Scotland)

Vidya R, Dixon JM.
PMID: 14965574
Breast. 2001 Apr;10(2):140-2. doi: 10.1054/brst.2000.0216.

This study compared the accuracy of interpretation by surgeons and radiologists of 1053 women who had two view mammography and a histological or cytological diagnosis of benign or malignant breast disease. Patients with large or locally advanced breast cancers...

Latissimus dorsi mini-flap: a technique for extending breast conservation.

Breast (Edinburgh, Scotland)

Dixon JM, Venizelos B, Chan P.
PMID: 14965647
Breast. 2002 Feb;11(1):58-65. doi: 10.1054/brst.2001.0312.

The latissimus dorsi (LD) flap was first used in patients for breast reconstruction in 1896. More recently it has been used to fill defects after quadrantectomy or very wide excision. We have developed a two stage procedure for excision...

Effects of component length and of the transitions among components in multiple schedules.

Journal of the experimental analysis of behavior

Hinson JM, Malone JC, McNally KA, Rowe DW.
PMID: 16812037
J Exp Anal Behav. 1978 Jan;29(1):3-16. doi: 10.1901/jeab.1978.29-3.

Pigeons received equal variable-interval reinforcement during presentations of two line-orientation stimuli while five other orientations appeared in extinction. Component duration was 30 seconds for all orientations and the sequence was arranged so that each orientation preceded itself and each...

Simultaneous spectrophotometric determination of cadmium, copper and zinc.

Talanta

Rodriguez AM, de Torres AG, Pavon JM, Ojeda CB.
PMID: 18965863
Talanta. 1993 Dec;40(12):1861-6. doi: 10.1016/0039-9140(93)80108-4.

A method for the simultaneous spectrophotometric determination of cadmium, copper and zinc based on the formation of their complexes with 1,5-bis(di-2-pyridylmethylene)thiocarbonohydrazide is proposed. The absorption curves of these complexes overlap severely in the scanning range 380-480 nm. The analyte...

Picolinaldehyde 4-phenyl-3-thiosemicarbazone as a spectrophotometric reagent for the selective determination of small amounts of cobalt in the presence of iron.

Talanta

Ariza JL, Pavon JM, Pino F.
PMID: 18961897
Talanta. 1976 Jun;23(6):460-2. doi: 10.1016/0039-9140(76)80129-4.

The characteristics and analytical applications of picolinaldehyde 4-phenyl-3-thiosemicarbazone are described. This compound gives coloured reactions with cobalt(II), iron(II) and (III), nickel(II), copper(II), palladium(II) and other ions, that are much more sensitive than those with picolinaldehyde thiosemicarbazone. The 1:2 yellow...

Cloning, sequence analysis and disruption of the mglA gene involved in swarming motility of Sorangium cellulosum So ce26, a producer of the antifungal polyketide antibiotic soraphen A.

Journal of bioscience and bioengineering

Zirkle R, Ligon JM, Molnár I.
PMID: 16233626
J Biosci Bioeng. 2004;97(4):267-74. doi: 10.1016/S1389-1723(04)70202-9.

The myxobacterium Sorangium cellulosum So ce26, the producer of the agriculturally important fungicide antibiotic soraphen A, displays coordinated gliding motility (swarming) on agar surfaces. The consequent failure to form detached colonies represents a major obstacle for microbiological and genetic...

Bragg spectroscopy of a strongly interacting 85Rb Bose-Einstein condensate.

Physical review letters

Papp SB, Pino JM, Wild RJ, Ronen S, Wieman CE, Jin DS, Cornell EA.
PMID: 18851457
Phys Rev Lett. 2008 Sep 26;101(13):135301. doi: 10.1103/PhysRevLett.101.135301. Epub 2008 Sep 22.

We report on measurements of the excitation spectrum of a strongly interacting Bose-Einstein condensate. A magnetic-field Feshbach resonance is used to tune atom-atom interactions in the condensate and to reach a regime where quantum depletion and beyond mean-field corrections...

The use of furfural thiosemicarbazone for the gravimetric determination of palladium.
