Botulinum Toxin A for Oral Cavity Cancer Patients: In Microsurgical Patients BTX Injections in Major Salivary Glands Temporarily Reduce Salivary Prod…
2012
Abstract: In patients suffering from oral cavity cancer surgical treatment is complex because it is necessary to remove carcinoma and lymph node metastasis (through a radical unilateral or bilateral neck dissection) and to reconstruct the affected area by means of free flaps. The saliva stagnation in the post-operative period is a risk factor with regard to local complications. Minor complications related to saliva stagnation (such as tissue maceration and wound dehiscence) could become major complications compromising the surgery or the reconstructive outcome. In fact the formation of oro-cutaneous fistula may cause infection, failure of the free flap, or the patient’s death with carotid b…
Best practices for International eSourcing of Software Products and Services
2008
This paper analyzes how the information and communications technology-supported international eSourcing of software products and services (IeS) can be effectively executed. The extant literature falls short of providing a systematic and detailed enough set of best practices to guide IeS. This paper presents best practices for IeS to facilitate further research, and to help managers and other stakeholders to understand, execute, and proactively improve and manage international eSourcing. The practices emphasize the need to establish and enact rigorous, mature, and quantitatively managed eSourcing life- cycles in order to transcend temporal, geographical, social, technical, and other boundari…
Síntesis de Protoberberinas y Ciclopentil-isoquinoleínas Dopaminérgicas, y Síntesis de Indenopiridinas Melatoninérgicas
2015
Resumen – Discusión de los resultados. En la presente Tesis Doctoral se han desarrollado diversas rutas de síntesis para la obtención de alcaloides isoquinoleínicos, con diferentes esqueletos, y de hexahidroindenopiridinas. Además se han realizado sus correspondientes ensayos farmacológicos, sobre distintas dianas biológicas basándonos en los resultados obtenidos previamente con este tipo de alcaloides de síntesis y/o aislados de la naturaleza, y de moléculas estructuralmente similares. Se ha observado, a lo largo de muchos años, que las IQ son uno de los metabolitos secundarios activos (MSA) más abundantes y de mayor interés farmacológico de los aislados en especies de la familia de las An…

First measurement of quarkonium polarization in nuclear collisions at the LHC
2021
The polarization of inclusive J/$\psi$ and $\Upsilon(1{\rm S})$ produced in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region $2.5<y<4$ and measuring the polar and azimuthal angular distributions of the muons. The polarization parameters $\lambda_{\theta}$, $\lambda_{\phi}$ and $\lambda_{\theta\phi}$ are measured in the helicity and Collins-Soper reference frames, in the transverse momentum interval $2<p_{\rm T}<10$ GeV/$c$ and $p_{\rm T}<15$ GeV/$c$ for the J/$\psi$ and $\Upsilon(1{\rm S})$, respectively. The polarization parameter…
UV filters: From sunscreens to human body and the environment
2007
Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…
Testing the nature of the Λ(1520)-resonance in proton-induced production
2006
The $\Lambda(1520)$ resonance has been recently studied in a unitarized coupled channel formalism with $\pi\Sigma(1385)$, $K\Xi(1530)$, $\bar{K}N$ and $\pi\Sigma$ as constituents blocks. We provide a theoretical study of the predictions of this model in physical observables of the $pp\to pK^+K^-p$ and $pp\to pK^+\pi^0\pi^0\Lambda$ reactions. In particular, we show that the ratio between the $\pi^0\pi^0\Lambda$ and $K^-p$ mass distributions can provide valuable information on the ratio of the couplings of the $\Lambda(1520)$ resonance to $\pi\Sigma(1385)$ and $\bar{K}N$ that the theory predicts. Calculations are done for energies which are accessible in an experimental facility like COSY at …

Elektroutlenianie przepracowanego oleju 15W-40
2017
W pracy przedstawiono badania nad możliwością wykorzystania odpadowego oleju silnikowego 15W-40 do bezpośredniego pozyskiwania energii elektrycznej. Pomiary obejmowały elektroutlenianie emulsji odpadowego (zużytego) oleju silnikowego 15W-40 na gładkiej elektrodzie platynowej w kwasowym elektrolicie (H2SO4). Do wytworzenia emulsji wykorzystano detergent Syntanol DS-10. Pomiary przeprowadzono w temperaturze 293-333K. Maksymalna uzyskana gęstość prądu wyniosła 19 mA/cm2 (dla temp. 333K). Badania wykazały możliwość bezpośredniego wytwarzania prądu elektrycznego z odpadowego oleju silnikowego 15W40, a więc możliwość zasilania nim ogniw paliwowych.
