Packaging reconditioned household appliances
This article aims to present a research and design work that focuses on exploring new possible approaches to packaging design as applied to the field of reconditioning and reintroducing old household appliances to the market
Media use during adolescence: the recommendations of the Italian Pediatric Society.
BACKGROUND: The use of media device, such as smartphone and tablet, is currently increasing, especially among the youngest. Adolescents spend more and more time with their smartphones consulting social media, mainly Facebook, Instagram and Twitter because. Adolescents often feel the necessity to use a media device as a means to construct a social identity and express themselves. For some children, smartphone ownership starts even sooner as young as 7 yrs, according to internet safety experts. MATERIAL AND METHODS: We analyzed the evidence on media use and its consequences in adolescence. RESULTS: In literature, smartphones and tablets use may negatively influences the psychophysical development of the adolescent, such as learning, sleep and sigh. Moreover, obesity, distraction, addiction, cyberbullism and Hikikomori phenomena are described in adolescents who use media device too frequently. The Italian Pediatric Society provide action-oriented recommendations for families and clinicians to avoid negative outcomes. CONCLUSIONS: Both parents and clinicians should be aware of the widespread phenomenon of media device use among adolescents and try to avoid psychophysical consequences on the youngest
Severe growth hormone deficiency and pituitary malformation in a patient with chromosome 2p25 duplication and 2q37 deletion.
We report on a male child ascertained at 4.8Â years of age with severe growth failure, growth hormone (GH) deficiency, psychomotor delay with prevalent speech impairment, and a distinct phenotype. An evaluation of his hypothalamic-pituitary region by Magnetic Resonance Imaging (MRI) revealed pituitary hypoplasia with pituitary stalk interruption and ectopic posterior pituitary lobe, which are considered prognostic markers of permanent GH deficiency. Prenatal chromosome analysis because of increased nuchal translucency revealed a normal male karyotype, whereas postnatal high resolution banding raised the suspicion of a 2q abnormality. Subsequently, array Comparative Genomic Hybridization (array-CGH) revealed a de novo complex genomic rearrangement consisting of a 2p25 duplication and a 2q37 deletion: arr[hg19] 2p25.3p25.1(30,341-9,588,369)x3,2q37.2q37.3(235,744,424-243,041,305)x1. FISH analysis showed that the abnormal chromosome 2 mimicked the derivative of an inversion with the duplicated 2p region located distally at 2q. This is, to the best of our knowledge, the first case with distal 2p25 duplication and 2q37 deletion and pituitary malformation leading to GH deficiency
MKRN3 and KISS1R mutations in precocious and early puberty
Background Pubertal timing is known to be influenced by interactions among various genetic, nutritional, environmental and socio-economic factors, although the ultimate mechanisms underlying the increase in pulsatile GnRH secretion at puberty have yet to be fully elucidated. The aim of our research was to verify the role of KISSR1 (previously named GPR54) and MKRN3 genes on pubertal timing. Methods We analyzed the DNA sequence of these genes in 13 girls affected by central precocious puberty (CPP) who showed onset of puberty before 8 years of age, and in 6 girls affected by early puberty (EP) between 8 and 10 years of age. Results Direct sequencing of the KISS1R (GPR54) gene revealed two SNPs. One SNP is a missense variant (rs 350,132) that has been previously reported in connection to CPP in Korean girls. The other variant that we found in the GPR54 gene (rs764046557) was a missense SNP located in exon 5 at position 209 of the aminoacid. We identified this variant in only one CPP patient. Automatic sequencing of MKRN3 in all patients revealed three variants in eight subjects. In 6 out of 19 (31.5%) patients (3/13 CPP patients and 3/6 EP patients) we found the synonymous variant c.663C > T (rs2239669). Another synonymous variant (rs140467331) was found in one of our CPP patients, as well as one missense variant (rs760981395) in another CPP patient. Conclusion In conclusion, we identified sequence variations of the KISS1R and MKRN3 genes, two of the most frequent genetic causes of ICPP. Our results suggest that these variants might be inducible factors in the pathogenesis of CPP
Installazioni per i percorsi Olimpici Invernali Torino 2006
Un itinerario sperimentale con installazioni innovative per l'informazione, il relax, il gioco, realizzate nell'ambito dell'operazione Design e Territorio, voluta dalla Camera di Commercio di Torino (ideata da A.Donini) in occasione dei XX Giochi Olimpici Invernali. All'operazione hanno preso parte 3 universitĂ italiane e francesi, con 7 tutor e 150 studenti (Politecnico di Torino Disegno Industriale, Ecole d'Architecture de Lyon, Ecole d'Architecture Languedoc - Roussilon de Montpellier)
Dalla montagna per la montagna. ESTBOIS, collezione di arredi per esterno.
Larice e frassino, legni tipici dell’arco alpino piemontese, sono alla base di un progetto partecipato di arredi per l'esterno, tra il Politecnico di Torino, la Comunità Montana e le imprese artigiane delle Valli del Monviso
Downside risk in reservoir management
Downside risk, which refers to deviations below a threshold, is often important in
water management decisions, especially in areas with large and skewed variations in
precipitation patterns. In this paper, we present a model for a reservoir manager who
is downside risk averse and who performs a dynamic allocation of irrigation water,
taking into account the negative effects of droughts on farm profits and different
environmental constraints. We analyse the water stock, flows and agricultural profits
for alternative environmental restrictions and thresholds for irrigation levels and find
that stricter environmental constraints increase total water supply and carryover
stock, while higher penalty thresholds lead to their overall decrease. Furthermore,
increasing penalty thresholds leads to a higher emphasis on avoiding shortages, at the
expense of lower average profits.info:eu-repo/semantics/acceptedVersio
I risultati
I progetti ideati e prototipati nell'ambito dell'operazione Arredo & Territorio, sono stati posizionati in modo permanente lungo i percorsi delle valli olimpiche in Piemonte, con l’intenzione di valorizzare il territorio e promuovere l’artigianato locale. Ciò è avvenuto attraverso la definizione di prodotti portatori di valori e significati nuovi, ossia manufatti artigianali “design oriented” che sono sintesi tra abilità realizzativa e profonda conoscenza dei materiali, tipiche del sapere artigiano, e nuove direzioni di fruizione del paesaggio.
