Alcohol abusive use increases facial trauma?
2016
Background Trauma is among the main death causes and morbidity in the world and is often related to the use of alcohol and its abuse has reached massive proportions, no matter if the country is developed or not, being considered as public health problem. Since there are very few randomized and prospective studies in literature about the association of facial trauma and the use of alcohol, this study aims to investigate the impact of alcohol use in facial trauma. Material and Methods This was a prospective and cross sectional study, involving facial trauma patients attended at Oral Maxillofacial Surgery Division of a State Hospital. Variables included patient´s profile, trauma etiology, faci…
A critical review on the implementation of static data sampling techniques to detect network attacks
2021
International audience; Given that the Internet traffic speed and volume are growing at a rapid pace, monitoring the network in a real-time manner has introduced several issues in terms of computing and storage capabilities. Fast processing of traffic data and early warnings on the detected attacks are required while maintaining a single pass over the traffic measurements. To palliate these problems, one can reduce the amount of traffic to be processed by using a sampling technique and detect the attacks based on the sampled traffic. Different parameters have an impact on the efficiency of this process, mainly, the applied sampling policy and sampling ratio. In this paper, we investigate th…
Lrp4, a Novel Receptor for Dickkopf 1 and Sclerostin, Is Expressed by Osteoblasts and Regulates Bone Growth and Turnover In Vivo
2009
Lrp4 is a multifunctional member of the low density lipoprotein-receptor gene family and a modulator of extracellular cell signaling pathways in development. For example, Lrp4 binds Wise, a secreted Wnt modulator and BMP antagonist. Lrp4 shares structural elements within the extracellular ligand binding domain with Lrp5 and Lrp6, two established Wnt co-receptors with important roles in osteogenesis. Sclerostin is a potent osteocyte secreted inhibitor of bone formation that directly binds Lrp5 and Lrp6 and modulates both BMP and Wnt signaling. The anti-osteogenic effect of sclerostin is thought to be mediated mainly by inhibition of Wnt signaling through Lrp5/6 within osteoblasts. Dickkopf1 …
Forensic mtDNA hair analysis excludes a dog from having caused a traffic accident
1999
A dog was suspected of having caused a traffic accident. Three hair fragments were recovered from the damaged car and subjected to DNA sequence analysis of the canine mitochondrial D-loop control region. The results were compared to saliva and hair samples from the alleged dog, as well as to control hair samples from four unrelated dogs of different breeds. Two sequence types exhibiting five nucleotide differences in a 377 bp fragment were identified among the four controls. Whereas the evidence hair fragment was identical to the type 1 control sequence, the alleged dog shared the type 2 control sequence except for one position. Thus the dog could be excluded as the origin of the hair fragm…
The influence of transport offer on passenger traffic in the railway transport system in a post-socialist country : case study of Poland
2021
Abstract The study examines factors influencing the number of rail passengers in Poland. The subjects of observation were 62 cities with poviat rights. The main factors influencing demand are the number of connections and the speed of trains. Therefore, we developed an original indicator – weighted number of connections, which takes into account the number of rail connections and the speed of trains. The article can be divided into two main parts: an assessment of the diversification of transport offer and transport demand in spatial terms, and an evaluation of the relationship between the variables. Poland has a large spatial diversity in terms of public rail transport offer and passenger …
La mafia in aeroporto. Punta raisi: cronaca di una speculazione annunciata
2013
The history of Palermo’s Punta Raisi Airport – that is called today “Falcone and Borsellino” in memory of the two judges killed by Cosa Nostra - started after World War II, coinciding with the increase of civilian air traffic in the skies of the Sicilian capital, third in Italy for its number of transits of passengers and freight, which became unsustainable figures for the military airport of Boccadifalco. Everything begins with the creation in 1953 of the Autonomous Consortium for the Airport of Palermo, with the aim to implement the project of a new infrastructure located a few steps away from the city center, ready to compete with the best airports in Italy, to increase the modernization…
Giustizia penale e tratta di esseri umani: i risvolti processuali della "vulnerabilità"
2017
Il contrasto dei fenomeni di tratta e di traffico di esseri umani mostra un processo di “contaminazione” fra normativa di tipo universale e regionale, caratterizzato dal rispetto dello standard di Duty of Due Diligence. Domina lo scenario italiano il concetto polifunzionale di “vulnerabilità”, direttamente trasfuso nella fattispecie sostanziale, recepito nel sistema processuale ed evidenziato da alcuni esiti giurisprudenziali. Esso, oltre a influenzare la determinazione del locus commissi delicti, gioca un ruolo di sicuro rilievo nel giustificare forme di anticipazione del contraddittorio e nel tratteggiare i contorni della prova dichiarativa “debole”. Ulteriori effetti la “vulnerabilità” e…
The effects of anthropogenic particulate emissions on roadway dust and Nerium oleander leaves in Messina (Sicily, Italy)
2003
Complementary studies on the inorganic chemical composition of Nerium oleander leaves collected in the town of Messina (Sicily, Italy) and seven grain-size fractions of local roadway dust have been carried out. Data and maps are presented to show that the particulate matter present in the air of Messina contains trace elements significantly in excess with respect to the average continental earth crust. The anomalies follow the outline of the urban area, the highest concentrations of trace elements being observed where traffic density is highest. Chemical and isotopic analyses of both road dust and Nerium oleander leaves indicate that Pb contamination still characterizes roads with heavy tra…
Efficiency Analysis Of Resource Request Patterns In Classification Of Web Robots And Humans
2018
The paper deals with the problem of classification of Web traffic generated by robots and humans on e-commerce websites. Due to the still growing proliferation and specialization of bots, a large body of research into characterization and recognition of their traffic has been conducted so far. In particular, some approaches to classify bot and human sessions on websites have been proposed in the literature. In this paper we verify and discuss the efficiency of such recently proposed approach, which uses differences in resource request patterns of bots and humans. We reconstructed Web sessions from actual HTTP log data for three different e-commerce sites, varying in the traffic intensity an…
Comparing the cycling behaviours of Australian, Chinese and Colombian cyclists using a behavioural questionnaire paradigm.
2020
Cyclists are vulnerable road users and face disproportionately high rates of road trauma, especially in low- and middle-income countries. Behaviour of road users is a system outcome, and thus studying cyclist behaviours can identify problems in the whole road transport system and assist in generating long-lasting, cost-effective solutions to promote cyclist safety. This study aims to investigate the similarities and disparities of cycling behaviour among countries with different income levels and cycling prevalence, and the relationships among cyclist demographic characteristics, behaviours and crash involvement. It applies the Cycling Behaviour Questionnaire (CBQ) to measure the behaviour …
