Track Momentum Discrimination Using Cluster Width in Silicon Strip Sensors for SLHC

The cluster width of a particle crossing a silicon strip (mini strip) detector can be exploited to measure its transverse momentum when the strips are parallel to the B field. This suggests the discrimination of the clusters widths to filter the majority of low momentum particles. Once performed directly on the detectors, such discrimination can be used both for low level trigger (L1) and for data reduction. This approach is discussed in the context of a first level trigger based on the Tracker for SLHC. The quality of the measurements and their discrimination capability are discussed with respect to the geometry of the sensors and to the detectors layout. Electronics issues and constraints are also reviewed

Elephant movement patterns in relation to human inhabitants in and around the Great Limpopo Transfrontier Park.

The presence of humans and African elephants (Loxodonta africana) in the Great Limpopo Transfrontier Park can create situations of potential human–elephant conflict. Such conflict will likely be exacerbated as elephant and human populations increase, unless mitigation measures are put in place. In this study we analysed the movement patterns of 13 collared adult African elephants from the northern Kruger National Park over a period of eight years (2006–2014). We compared the occurrence and displacement rates of elephant bulls and cows around villages in the Limpopo National Park and northern border of the Kruger National Park across seasons and at different times of the day. Elephants occurred close to villages more often in the dry season than in the wet season, with bulls occurring more frequently around villages than cows. Both the bulls and the cows preferred to use areas close to villages from early evening to midnight, with the bulls moving closer to villages than the cows. These results suggest that elephants, especially the bulls, are moving through the studied villages in Mozambique and Zimbabwe at night and that these movements are most common during the drier months when resources are known to be scarce. Conservation implications: Elephants from the Kruger National Park are moving in close proximity to villages within the Great Limpopo Transfrontier Park. Resettlement of villages within and around the park should therefore be planned away from elephant seasonal routes to minimise conflict between humans and elephants

Micro-beam and pulsed laser beam techniques for the micro-fabrication of diamond surface and bulk structures

Micro-fabrication in diamond is involved in a wide set of emerging technologies, exploiting the exceptional characteristics of diamond for application in bio-physics, photonics, radiation detection. Micro ion-beam irradiation and pulsed laser irradiation are complementary techniques, which permit the implementation of complex geometries, by modification and functionalization of surface and/or bulk material, modifying the optical, electrical and mechanical characteristics of the material. In this article we summarize the work done in Florence (Italy) concerning ion beam and pulsed laser beam micro-fabrication in diamond.Comment: 14 pages, 5 figure

Preliminary Report on the Efficacy of Music Therapy to Optimize the Compliance of Rett Syndrome Patients Attending Oral Hygiene Procedures

Background: Individuals with intellectual developmental disability (IDD) often face barriers in accessing dental care. The main aim of the present study was to test the feasibility and the outcome of oral hygiene (OH) procedures in Rett syndrome (RS) patients, and a secondary aim was to test the utility of music therapy during dental hygiene procedures. Methods: A case group (Group 1) of female patients with RS (stage 3 of disease, age > 5 years and <18 years) and a control group of age-matched healthy females (Group 0) were formed, and subgroups received the intervention of oral hygiene combined with a music therapy (Subgroup 1M and Subgroup 0M) or standard oral hygiene (subgroup 1W and subgroup 0W). The Simplified Oral Hygiene Index (OHI-S) was used to assess the effectiveness of oral hygiene measures. Results: The OHI-S at T0 was 1.41 in Group 1 and 2.58 in Group 0 (p value < 0.001). The mean duration of the oral hygiene treatment was 7018′′ (SD 3272′′) in Group 1 and 873′′ (SD 161′′) in Group 0 (p value < 0.001). The mean duration of OH was significantly higher in Subgroup 1M and Subgroup 0M. Discussion: Based on the results of our case-control study, OH procedures can be successfully performed in RS patients with good compliance and efficacy. In addition, our study provides preliminary evidence to suggest that music therapy may be a useful adjunct, as it appears to improve patient cooperation

Cardoon meal as alternative protein source to soybean meal for limousine bulls fattening period: Effects on growth performances and meat quality traits

SIMPLE SUMMARY: Beef cattle feeding strategies are commonly based on soybean meal utilization as a fundamental protein source. This feed, though, might have negative environmental impacts on the major areas of production and is becoming very expensive. Cardoon (Cynara cardunculus L.) is a resilient crop which represents a good opportunity in reclaiming and remediating unutilized lands. Cardoon seeds are rich in oil, which is extracted for industrial purposes, and the related by-products (press cake and meal) are characterized by high protein content and essential fatty acids. The aim of this study was to evaluate cardoon meal as a protein source during the Limousine bulls’ fattening period, in order to study a suitable alternative to develop and create low-input and low-emission feeding strategies. The results obtained in terms of growth performances showed no statistical difference between bulls fed the by control diet (containing soybean meal as main protein source) and animals fed by the experimental diet, where soybean meal was partially replaced by one containing cardoon meal. Meat quality traits were measured, and no differences between the groups were found. Hence, these by-products could be considered as a valuable solution in Limousine bulls’ fattening periods and could be used to represent a key factor to improve cattle-feeding sustainability. ABSTRACT: Soybean meal is the most important protein source in beef cattle feeding. The research of alternative protein sources to replace soy use, avoiding negative effects on in vivo performance and on the product’s quality, is an important issue. In this context, cardoon represents a non-OGM resilient crop that can be cultivated in marginal lands for extracting its seed oil (utilized for biodiesel and biodegradable bioplastic production) and whose and the residual meal from its seed oil (utilized for biodiesel and biodegradable bioplastic production) could be a suitable by-product for animal feeding, due to its fairly high protein content. The aim of this study was to evaluate the feasibility of using cardoon meal as an innovative protein source during the Limousine bulls’ fattening period. Thirty-two bulls were divided into two groups and fed with a diet containing soybean meal (SG) or partially replacing soybean meal with cardoon meal as a protein source (CG), respectively. The feeding trial lasted about 11 months. Growth performances and meat physical–chemical traits were evaluated. No statistical differences in feed efficiency, average daily gain, or in the main meat quality indicators, as well as in fatty acid profiles were found among the groups. Therefore, cardoon meal could be considered as an alternative to soybean meal in fattening Limousine bulls in order to enhance the sustainability of the farming system
