Nerve Entrapment.

Seminars in musculoskeletal radiology

Beltran J, Rosenberg ZS.
PMID: 11387100
Semin Musculoskelet Radiol. 1998;2(2):175-184. doi: 10.1055/s-2008-1080098.

Entrapment and compressive neuropathies are frequent clinical conditions occurring about the elbow. In most instances clinical and electromyograhic evaluation are adequate for patient management, but in some cases further evaluation with imaging techniques is required. Magnetic resonance imaging (MRI)...

Application of solid phase microextraction for the determination of soil fumigants in water and soil samples.

Journal of separation science

Fuster S, Beltran J, López FJ, Hernández F.
PMID: 15688638
J Sep Sci. 2005 Jan;28(1):98-103. doi: 10.1002/jssc.200401888.

The potential of solid phase microextraction (SPME) for the determination of the soil fumigants 1,3-dichloropropene (1,3-DCP) and methyl isothiocyanate (MITC) in environmental samples such as soil and water samples has been investigated. Direct immersion SPME followed by GC/ECD/NPD analysis...

Extraction of elemental sulfur from an aqueous suspension for analysis by high-performance liquid chromatography.

Analytical chemistry

Henshaw PF, Bewtra JK, Biswas N.
PMID: 21639333
Anal Chem. 1997 Aug 01;69(15):3119-23. doi: 10.1021/ac961149p.

A bioreactor is being developed that produces elemental sulfur suspended in aqueous bioreactor contents. The concentration of elemental sulfur must be measured explicitly in order to study the efficiency of the conversion of sulfide to elemental sulfur. Extracting the...

Determination of volatile organic compounds in water by headspace solid-phase microextraction gas chromatography coupled to tandem mass spectrometry with triple quadrupole analyzer.

Analytica chimica acta

Cervera MI, Beltran J, Lopez FJ, Hernandez F.
PMID: 21907025
Anal Chim Acta. 2011 Oct 17;704(1):87-97. doi: 10.1016/j.aca.2011.08.012. Epub 2011 Aug 11.

In the present work, a rapid method with little sample handling has been developed for determination of 23 selected volatile organic compounds in environmental and wastewater samples. The method is based on headspace solid-phase microextraction (SPME) followed by gas...

Effect of transport time on welfare and meat quality in pigs.

Meat science

Pérez MP, Palacio J, Santolaria MP, Aceña MC, Chacón G, Gascón M, Calvo JH, Zaragoza P, Beltran JA, García-Belenguer S.
PMID: 22061073
Meat Sci. 2002 Aug;61(4):425-33. doi: 10.1016/s0309-1740(01)00216-9.

The purpose of this study was to determine the effects of transport duration on some welfare and meat quality parameters. For the study 144 pigs were used. One group of 72 animals was subjected to 15 min and the...

Phenol conversion and dimeric intermediates in horseradish peroxidase-catalyzed phenol removal from water.

Environmental science & technology

Orbital trajectory of an acoustic bubble in a cylindrical resonator.

Physical review. E, Statistical, nonlinear, and soft matter physics

Desjouy C, Labelle P, Gilles B, Bera JC, Inserra C.
PMID: 24125343
Phys Rev E Stat Nonlin Soft Matter Phys. 2013 Sep;88(3):033006. doi: 10.1103/PhysRevE.88.033006. Epub 2013 Sep 09.

Acoustic cavitation-induced microbubbles in a cylindrical resonator filled with water tend to concentrate into ring patterns due to the cylindrical geometry of the system. The shape of these ring patterns is directly linked to the Bjerknes force distribution in...

Clinical Implementation of Robust Optimization for Craniospinal Irradiation.

Cancers

Tasson A, Laack NN, Beltran C.
PMID: 29301336
Cancers (Basel). 2018 Jan 03;10(1). doi: 10.3390/cancers10010007.

With robust optimization for spot scanning proton therapy now commercially available, the ability exists to account for setup, range, and interfield uncertainties during optimization. Robust optimization is particularly beneficial for craniospinal irradiation (CSI) where the large target volume lends...

Parametric Shape Optimization of Lens-Focused Piezoelectric Ultrasound Transducers.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Thomas GPL, Chapelon JY, Bera JC, Lafon C.
PMID: 29733286
IEEE Trans Ultrason Ferroelectr Freq Control. 2018 May;65(5):844-850. doi: 10.1109/TUFFC.2018.2817927.

Focused transducers composed of flat piezoelectric ceramic coupled with an acoustic lens present an economical alternative to curved piezoelectric ceramics and are already in use in a variety of fields. Using a displacement/pressure (u/p) mixed finite element formulation combined...

Retention capacity of dry soils for NAPLs.

Environmental technology

Zytner RG, Biswas N, Bewtra JK.
PMID: 29016266
Environ Technol. 1993 Nov;14(11):1073-1080. doi: 10.1080/09593339309385384.

Retention capacity values were measured in the laboratory for three non-aqueous phase liquids (NAPLs), PCE, TCE and gasoline. The dry soils studied were sandy loam, clay, organic top soil and peat moss. For the conditions tested, it was determined...

Carbon Ion Therapy: A Modern Review of an Emerging Technology.
