Radiation Hardness tests with neutron flux on different Silicon photomultiplier devices

Radiation hardness is an important requirement for solid state readout devices operating in high radiation environments common in particle physics experiments. The MEGII experiment, at PSI, Switzerland, investigates the forbidden decay $\mu^+ \to \mathrm{e}^+ \gamma$. Exploiting the most intense muon beam of the world. A significant flux of non-thermal neutrons (kinetic energy $E_k\geq 0.5 ~MeV$) is present in the experimental hall produced along the beamline and in the hall itself. We present the effects of neutron fluxes comparable to the MEGII expected doses on several Silicon PhotoMulitpliers (SiPMs). The tested models are: AdvanSiD ASD-NUV3S-P50 (used in MEGII experiment), AdvanSiD ASD-NUV3S-P40, AdvanSiD ASD-RGB3S-P40, Hamamatsu and Excelitas C30742-33-050-X. The neutron source is the thermal Sub-critical Multiplication complex (SM1) moderated with water, located at the University of Pavia (Italy). We report the change of SiPMs most important electric parameters: dark current, dark pulse frequency, gain, direct bias resistance, as a function of the integrated neutron fluency.Comment: 9 pages, 6 figures.

Karyology and cytotaxonomy of the genus Passiflora L. (Pasifloraseae).

The chromosomes of 31 species of Pas- siflora, distributed throughout the subgenera As- trophea, Calopathanthus, Distephana, Dysosmia, Passiflora, Plectostemma and Tacsonia were ana1- ysed. Three different karyotypes were observed: 2n = 12, 24, 36; 2n = 18, 72 and 2n = 20. The karyotype of these species was a1most always constituted of metacentric and submetacentric chromosomes with variable karyotype symmetry. In the group with x = 6, represented by the subgenus Plectostemma, six diploid species with 2n = 12, one tetraploid with 2n = 24 (P. suberosa) and an intraspecific polyploid with 2n = 12, 36 (P. misera) were analysed. P. pentagona (subgenus Astrophea) may also be included in this karyolog- ical group since it presents 2n = 24 and may be of polyploid origin, with x = 6. The interphase nuclei in this group were areticulate, except those of P. morifolia and P. pentagona with semi-reticulate characteristics. Two small terminal heterochroma- tic blocks, positive for chromomycin A3, were identified in the largest chromosome pair of P. capsularis and P. rubra, species very closely related, while P. tricuspis displayed four chromo- somes with proximal blocks. In the group with x = 9, represented mainly by subgenus Passiflora, 20 species with 2n = 18 and one with 2n = 72 were studied. They presented chromosomes larger than those species with x = 6 and interphase nuclei of semi-reticulate type, except for P. mixta with areticulate nuclei. Four terminal CMA + block: were observed in P. edulis, six blocks in P. caerulel and P. racemosa, while five blocks were observed ir the single P. amethystina plant analysed. P. foetid\{ (subgenus Dysosmia), the only species witt 2n = 20, exhibited six chromosomes with CMA + blocks and interphase nuclei of the areticulate type The meiotic analysis of representatives of the three groups (P. foetida, P. suberosa, P. cincinnata and P. racemosa) always presented regular pairing and regular chromosome segregation, except in P.jilekil where a tetravalent was observed. The analysis of the chromosome variation within the genus and the family suggests that the base number of Passiflora may be xi = 6 or XI = 12, whereas X2 = 9 is only an important secondary base number

Expansion of the core business of traditional media companies in Spain through SVOD services

The strategic importance of the internet for television became evident in the early 2000s, even destabilizing its very concept and finally resulting in convergence towards a profound transformation of the sector. The introduction of global over-the-top (OTT) media services into local markets has led to strategic changes in multimedia groups. This study considers the subscription video-on-demand (SVOD) services of Atresmedia and Mediaset España, the two main traditional media organizations in Spain that form a duopoly in the country’s commercial television sector, with the aim of understanding and evaluating their positioning strategy in this market and the results obtained through the diversification of their core business. Based on an analysis of their content, price, and promotion policies and the results in terms of subscriptions and revenues, slight differences emerge regarding the strategy and scope of these two groups in their own environment in the sector. They compete for customers to achieve growth in the audiovisual market while seeking to retain a cross-media, multiplatform audience, as well as expand their core business of commercial linear television against a background of a reduction of advertising spend on television and the expected increase of hybrid financing models

Reproductive parameters of "Nero di Parma" sows reared outdoor and indoor

AbstractThe swine genetic type "Nero di Parma" has been obtained after a preservation programme of a local breed suitable for outdoor rearing systems in Parma province. Actually, 480 females and 35 males are registered by Italian Swine Breeders Association and are reared in 28 herds of Parma province. The study involved the analysis of the reproductive performance of 120 sows from 19 boars, born between 1999 and 2005, during 211 parities from 2002 to 2006. For each parity, the boar, the age of the sow, the length of the farrowing interval, and the litter size (number of born alive, stillborn and weaned piglets) were recorded. Two rearing systems of the farrowing sows (from the final phase of gestation to the end of lactation) were considered: indoor (sows closed off in individual stalls or farrowing cages) and outdoor (sows in individual huts inside the paddocks, with straw bedding); dry sows in both systems had access on pasture with forage and concentrate integration. Data concerning sows performance we..

Primary Absence of Type II Endoleak is A Positive Prognostic Factor against the Risk of Late Conversion of EVAR for AAA

Introduction: The aim of this study is to analyze 12 late conversion to open surgery after Endovascular Repair of Abdominal Aortic Aneurysms (EVAR) while comparing the follow up of these cases to that of the definitely successful procedures (absence of surgical conversion, type I or III endoleaks, or presence of type II endoleaks without any aneurysmal sac enlargement) . Methods: From a series of over 300 EVAR procedures performed at our department we have selected 215 cases with a follow up ≥ 6 month and primary technical success (successful deployment of the devices and discharge of patients without neither type I nor III endoleaks). Based on the final data recorded at the end of the follow up (mean+ IQR: 38.16 months + 41), these cases were divided into three groups: group 1, with 12 cases (5.6%) which needed surgical conversion in a later stage (5 to 55 months from EVAR); group 2, with 39 cases (18.1%) with type II endoleaks without aneurysmal sac enlargement; group 3, with 164 cases (76.5%) without endoleaks. The groups were compared in relation to the following parameters: a) personal data and common atherogenic risk factor, b) diameter of the aneurysm, c) kind of the proximal fixation of the endograft (suprarenal or infrarenal), d) presence of endoleaks at the first postoperative check. We have compared the data from the three groups and we have analyzed them with chi-square test (Χ2). Results: Personal data and common atherogenic risk factor have proved no significant difference among the three groups. The incidence of the other three parameters of group 1 was compared with the incidence of these in groups 2 and 3: the mean pre-operative diameter of the aneurysm results 51 mm in group 1, 54 mm in group 2 and 55 mm in group 3 (not significant); suprarenal fixation of the prosthesis accounts for 50% in group 1, 51% in group 2 and 60% in group 3 (not significant); presence of type II endoleak at the first post-operative check was 41.6% in group 1, 56.4% in group 2 (not significant) and 9.7% in group 3 (p<0.001, compared to groups 1 and 2). Conclusion: In the EVAR procedures with primary technical success, the absence of type II endoleak at the first post-operative check represents a favorable prognostic factor against the risk of late conversion to open repair. Personal data, common atherogenic risk factor, diameter of the aneurysm and fixing type of the prosthesis don’t seem to influence the onset of this complication
