- A fully instrumented slice of the ATLAS central detector was exposed to test beams from the SPS (Super Proton Synchrotron) at CERN in 2004. in this paper, the response of the central calorimeters to pions with energies in the range between 3 and 9 GeV is presented. The linearity and the resolution of the combined calorimetry (electromagnetic and hadronic calorimeters) was measured and compared to the prediction of a detector simulation program using the toolkit Geant 4.

Genome sequence of Aedes aegypti, a major arbovirus vector.
- 2007

In: Science (New York, N.Y.). - : American Association for the Advancement of Science (AAAS). - 1095-9203 .- 0036-8075. ; 316:5832, s. 1718-23

Journal article (peer-reviewed)abstract
- We present a draft sequence of the genome of Aedes aegypti, the primary vector for yellow fever and dengue fever, which at approximately 1376 million base pairs is about 5 times the size of the genome of the malaria vector Anopheles gambiae. Nearly 50% of the Ae. aegypti genome consists of transposable elements. These contribute to a factor of approximately 4 to 6 increase in average gene length and in sizes of intergenic regions relative to An. gambiae and Drosophila melanogaster. Nonetheless, chromosomal synteny is generally maintained among all three insects, although conservation of orthologous gene order is higher (by a factor of approximately 2) between the mosquito species than between either of them and the fruit fly. An increase in genes encoding odorant binding, cytochrome P450, and cuticle domains relative to An. gambiae suggests that members of these protein families underpin some of the biological differences between the two mosquito species.

PRINTO/PRES international website for families of children with rheumatic diseases: www.pediatric-rheumatology.printo.it
- 2005
-
In: Ann Rheum Dis. - : BMJ. - 0003-4967. ; 64:7, s. 1101-6
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: To prepare a website for families and health professionals containing up to date information about paediatric rheumatic diseases (PRD). METHODS: Firstly, paediatric rheumatology centres and family self help associations were surveyed to characterise current clinical practice of physicians providing care for children with PRD, research activities, and training facilities of each centre. Secondly, international consensus was reached on the content of the website. Finally, the website was developed and the texts translated. RESULTS: The web page contains three main sections: (a) description for families of the characteristics of 15 PRD; (b) list of paediatric rheumatology centres; (c) contact information for family self help associations. A version for 45 countries in 52 languages (with another three in progress) is now available on the web. 291 surveys from 171 centres and 102 family associations were received from 42 countries. The median proportion of time spent in paediatric practice in the centres examined was 100%, with 70% of this time dedicated to paediatric rheumatology. 90% of the centres were willing to perform clinical trials in the future. CONCLUSIONS: The PRINTO/PRES website provides a well defined and competent set of information about PRD, with appropriate multiple translated versions and easy web navigational direction.

Single-step electrodeposition of polycrystalline CdSe microwire arrays : structural and optical properties
- 2008
-
In: APPLIED PHYSICS A-MATERIALS SCIENCE & PROCESSING. - : Springer Berlin/Heidelberg. - 0947-8396. ; 90:3, s. 423-430
-
Journal article (peer-reviewed)abstract
- In this work we report on the single-step synthesis of CdSe microwires with good crystalline characteristics by template-assisted electrochemical deposition from an electrolytic solution containing CdSO4Ce+CeSeO2 and sulfuric acid. Deposition was conducted at three different temperatures (25 degrees C, 60 degrees C and 80 degrees C) under potentiostatic control using a commercial nanoporous alumina membrane as the working electrode. The best results were obtained when the electrodeposition was carried out at E=-0.610 V vs. Ag/AgCl and T=80 degrees C. Under these experimental conditions, the microwires are uniform, well aligned, have a high packing density, and present a good crystalline character according to XRD analysis. TEM observations revealed that they are dense and continuous, with a mean diameter ranging from 360-380 nm, greater than the channel diameters of the alumina template used. A detailed study of the reflectance in the region close to CdSe bandgap energy allows the determination of a weak direct absorption edge at 1.65 eV, close to the bulk bandgap energy. The Raman spectra consist of a strong mode centered at 208 cm(-1) arising from the LO phonon and a somewhat weak, but still strong, mode arising from the second order LO (2LO) appearing at 415 cm(-1)

Vaccination technique, PPD reaction and BCG scarring in a cohort of children born in Guinea-Bissau 2000-2002

- The rates of positive tuberculin skin test (TST) reactions and BCG scarring after BCG vaccination vary between studies and populations. Tuberculin reactivity and BCG scarring may be related to better child survival in low-income countries. We therefore studied determinants for TST reaction and scarring in Guinea-Bissau. In a cohort of children born in suburban Bissau from March 2000 to July 2002, we assessed a Mantoux test with Purified protein derivative (PPD) (SSI, 2 T.U.) at 2 (2689 children), 6 (N= 2148) and 12 months (N= 1638) of age, and BCG scar was assessed at 2 (N= 2698) and 6 months (N= 2225) of age. In a subgroup of the children the vaccination technique was monitored by direct observation of post-vaccination wheal and route of administration. Three different types of BCG vaccine supplied by the local Extended Programme on Immunization were used. At 6 months of age the rate of PPD reactors (> 1 mm) after BCG vaccination was 25% and the rate of scarring was 89%. One BCG strain was associated with fewer PPD reactors (OR = 0.54 (0.31-0.91)) and BCG scars (OR = 0.13 (0.05-0.37)) and larger post-vaccination wheals produced more PPD reactions (OR 1.21 (95% Cl 1.02-1.43)) and BCG scars (OR 1.66 (1.24-2.21)). In the multivariable analyses of BCG-vaccinated children assessed at 6 months of age, monitoring of vaccination technique and type of BCG vaccine were important. This was not changed by control for other determinants, including sex, season, vaccination place, birthplace, ethnic group, low birth weight, place of residence, education and civil status of mother. We reason that vaccination. technique and BCG strain are important for PPD reaction and scarring in response to BCG vaccination. Considering that these responses are associated with better infant survival, the importance of monitoring vaccination technique and of different BCG strains should be evaluated with respect to infant mortality.
