The recent interest in human-robot interaction requires the development of new gripping solutions, compared to those already available and widely used. One of the most advanced solutions in nature is that of the human hand, and several research contributions try to replicate its functionality. Technological advances in manufacturing technologies and design tools are opening possibilities in the design of new solutions. The paper reports the results of the design of an underactuated artificial robotic hand, designed by exploiting the benefits offered by additive manufacturing technologies.
In Italy, the only prevalence study carried out with rigorous methodology in a sample of children and adolescents found that about 8% met criteria for any mental disorders. However, there is no systematic information available about the sociodemographic, clinical and treatment-related characteristics of young patients in contact with Child and Adolescent Mental Health Services (CAMHS).
To assess the characteristics of children and adolescents in contact with CAMHS and to analyse the pathways through which they referred to services.
All public outpatient CAMHS operating in a Region of 633,725 inhabitants aged 6–17 years participated to the study. A total of 710 consecutive patients were enrolled and were evaluated with a detailed Sociodemografic Form, and standardized assessment instruments, including the CBCL, the HoNOSCA, the C-GAS, the CGI.
The mean age of the users was 10(± 3) years, about 60% was male, and they were comparable to general population in terms of nationality, living situation and socioeconomic status. A large proportion (76%) of patients were diagnosed within the broad groups of emotional and specific developmental disorders. Most parents had been referred by general practitioners (48,2%), and/or by school teacher (31,9%); About 60% had never received any treatment before the first contact with CAMHS.
Overall, patients do not come from families with disadvantaged social and economic backgrounds; adolescent with behavioural disorders seems to require more intensive levels of care. the recognition of the patient's problems by parents and general practitioners play a central role in the referral pathway to CAMHS.
Although service data are crucial for estimating the resources required by Child and Adolescent Mental Health Services (CAMHS) and to improve their quality, no studies have yet been conducted in Italy to this aim, and even in other countries health services research in this area has been extremely limited in scope and magnitude.
To collect data on the physical characteristics, staffing arrangements, and activities of CAMHS in Emilia-Romagna, a densely populated Italian region with 633,725 inhabitants aged 0–17 years.
Unit Chiefs of all the CAMHS filled in a structured ‘Facility Form’, with activity data referring to 2008 (for inpatient facilities we referred to 2009).
Eleven CAMHS were operative, including 110 outpatient units, with a ratio of approximately 20 child psychiatrists and 23 psychologists per 100,000 inhabitants aged 0–17 years. All outpatient units were well equipped and all granted free service access. in 2008, approximately 6% of the target population was in contact with CAMHS; first-ever contacts accounted for 30% of annual visits. Hospital bed availability was 5 per 100,000 inhabitants aged 0–17 years.
The overall number of child psychiatrists per 100,000 inhabitants is one of the highest in Europe and is comparable with the most well equipped areas in the US. This comparison should be interpreted with caution, however, because in Italy, child psychiatrists also treat neurological disorders. Critical areas requiring improvement are: the uneven utilisation of standardised assessment procedures and the limited availability of dedicated emergency services during non-office hours.
This work proposes a chipless radio frequency identification approach based on the working principle of the harmonic radar. A frequency multiplication stage is performed by a non-linearity (i.e. a Shottky diode) on the tag in order for the tag answer to be insulated from the interrogation signal, thus avoiding the need for clutter cancellation techniques. Firstly, the performance of a simple one-bit harmonic tag relying on a low-power frequency doubler is analyzed and then a novel crack sensor, implemented by adding a disposable band-stop filter, is presented. Both solutions demonstrate tag-to-reader operational distances beyond 1 m. The characterizing blocks (namely the frequency doubler and the filter) are fabricated on cellulose substrates (i.e. regular photographic paper), thus being conformal to their implementation for applications in the new paradigm of Internet of Things.
Gamma-ray burst host galaxies are deficient in molecular gas, and show anomalous metal-poor regions close to GRB positions. Using recent Australia Telescope Compact Array (ATCA) Hi observations we show that they have substantial atomic gas reservoirs. This suggests that star formation in these galaxies may be fuelled by recent inflow of metal-poor atomic gas. While this process is debated, it can happen in low-metallicity gas near the onset of star formation because gas cooling (necessary for star formation) is faster than the Hi-to-H2 conversion.
Improving the efficiency of outbreak investigation in restaurants is critical to reducing outbreak-associated illness and improving prevention strategies. Because clinical characteristics of outbreaks are usually available before results of laboratory testing, we examined their use for determining contributing factors in outbreaks caused by restaurants. All confirmed foodborne outbreaks reported to the Centers for Disease Control and Prevention (CDC) from 1982 to 1997 were reviewed. Clinical profiles were developed based on outbreak characteristics. We compared the percentage of contributing factors by known agent and clinical profile to their occurrence in outbreaks of unclassified aetiology. In total, 2246 foodborne outbreaks were included: 697 (31%) with known aetiology and 1549 (69%) with aetiology undetermined. Salmonella accounted for 65% of outbreaks with a known aetiology. Norovirus-like clinical profiles were noted in 54% of outbreaks with undetermined aetiology. Improper holding times and temperatures were associated with outbreaks caused by Clostridium perfringens, Bacillus cereus, Staphylococcus aureus, and Salmonella, and also with outbreaks of undetermined aetiology that fitted diarrhoea-toxin and vomiting-toxin clinical profiles. Poor personal hygiene was associated with norovirus, Shigella, and Salmonella, and also with outbreaks that fitted norovirus-like and vomiting-toxin clinical profiles. Contributing factors were similar for outbreaks with known aetiology and for those where aetiology was assigned by corresponding clinical profile. Rapidly categorizing outbreaks by clinical profile, before results of laboratory testing are available, can help identification of factors which contributed to the occurrence of the outbreak and will promote timely and efficient outbreak investigations.
REM (Rapid Eye Mount) is a fully robotized fast slewing telescope equipped with a high throughput Near InfraRed (Z′, J, H, K′) camera (REMIR) and an optical slitless spectrograph (ROSS). A dedicated software for data reduction and software (AQuA) has been developed to extract scientific information from REM images without any human intervent. REM is installed in La Silla (Chile) and dedicated to detect and study the prompt optical/IR afterglow of Gamma Ray Bursts with the ambitious project of discovering objects at extremely high redshift. The synergy between REMIR camera and ROSS makes REM a powerful observing tool for any kind of fast transient phenomena.
Preliminary results of the 4He relative abundance determination from Radio Recombination Lines observations at different frequencies in the Orion, Rosette and W3 HII regions are presented. The Orion HII region has been mapped at both 22 GHz and 36 GHz with the same beamwidth (2 arcmin) using the Medicina and Puschino radio telescopes respectively. The RRLs parameters, together with their variation with frequency and with distance were determined by centering the map on the star θ1OriC. Three positions were observed in the Rosette HII region at 8.3 GHz leading to the first detection in this region of the transition He92α. The derived 4He relative abundance is considerably greater than the ones obtained from previous measurements. The W3 HII region was observed at 36 GHz and the 4He/H value derived was compared with previous measurements performed with higher spatial resolution.
