HPLC determination of theophylline and paracetamol in fresh and powdered milk
Poster presented at the 1st International Congress of CiiEM - From Basic Sciences to Clinical Research. 27-28 November 2015, Egas Moniz, Caparica, Portugal"Theophylline and paracetamol are drugs used worldwide both in human and veterinary medicine. Paracetamol (or acetaminophen) is employed as analgesic and antipyretic, and theophylline is a bronchodilator drug used in the treatment of asthma and chronic obstructive pulmonary disease. Both drugs are extensively used in pediatrics and their dosage is based on the child's body weight. Due to possible liver toxicity (paracetamol) and narrow therapeutic index (theophylline) it is imperative to carefully select and monitor the dose administered to children. Additionally, the recent proposal of milk as a platform to deliver drugs in pediatrics has prompted the development of a simple and sensitive high-performance liquid chromatography (HPLC) quantification method, of both theophylline and paracetamol, in the complex matrix that milk represents."Fundação para a Ciência e a Tecnologia (PTDC/DTP-FTO/1057/2012

Optical and Near Infrared Study of the Cepheus E outflow, a very low excitation object
We present images and spectra of the Cepheus E (Cep E) region at both optical
and infrared wavelengths. Only the brightest region of the southern lobe of the
Cep E outflow reveals optical emission, suggesting that the extinction close to
the outflow source plays an important r\^ole in the observed difference between
the optical and IR morphologies. Cep E is a unique object since it provides a
link between the spectroscopic properties of the optical Herbig-Haro (HH)
objects and those of deeply embedded outflows.Comment: Accepted Astron. J., 8 files: paper, tables plus 6 figure
High coercivity induced by mechanical milling in cobalt ferrite powders
In this work we report a study of the magnetic behavior of ferrimagnetic
oxide CoFe2O4 treated by mechanical milling with different grinding balls. The
cobalt ferrite nanoparticles were prepared using a simple hydrothermal method
and annealed at 500oC. The non-milled sample presented coercivity of about 1.9
kOe, saturation magnetization of 69.5 emu/g, and a remanence ratio of 0.42.
After milling, two samples attained coercivity of 4.2 and 4.1 kOe, and
saturation magnetization of 67.0 and 71.4 emu/g respectively. The remanence
ratio MR/MS for these samples increase to 0.49 and 0.51, respectively. To
investigate the influence of the microstructure on the magnetic behavior of
these samples, we used X-ray powder diffraction (XPD), transmission electron
microscopy (TEM), and vibrating sample magnetometry (VSM). The XPD analysis by
the Williamson-Hall plot was used to estimate the average crystallite size and
strain induced by mechanical milling in the samples
