Milk Bottles revisited social learning and individual variation in the blue tit cyanistes caeruleus
Animal Behaviour, 2013Co-Authors: Lucy M Aplin, Ben C Sheldon, Julie MorandferronAbstract:Blue tits are famous for the ‘Milk Bottle’ innovation, which emerged at numerous sites across Britain in the early 20th century. However, overall we still know little about the factors that foster or hinder the spread of innovations, or of the impact of individual differences in behaviour on social transmission. We used a two-action and control experimental design to study the diffusion of innovation in groups of wild-caught blue tits, and found strong evidence that individuals can use social learning to acquire novel foraging skills. We then measured six individual characteristics, including innovative problem solving, to investigate potential correlates of individual social-learning tendency. Consistent with a hypothesis of common mechanisms underlying both processes, we found evidence for a relationship between social learning and innovativeness. In addition, we observed significant age- and sex-biased social learning, with juvenile females twice as likely to acquire the novel skill as other birds. Social learning was also more likely in subordinate males than dominant males. Our results identify individual variation and transmission biases that have potential implications for the diffusion of innovations in natural populations.

Maloclusión clase III tratada con máscara facial
Universidad de Ciencias Médicas de Pinar del Río, 2018Co-Authors: Bioti Torres, Analina Mercedes, Torres Lima Mariagny, Rezk Díaz Anay, Morejón Fernández, Alberto CarlosAbstract:Introduction: class III dentoskeletal malocclusion has been considered throughout history as one of the most striking malocclusions due to the facial deformity it can provoke. Making it one of the most complex and difficult orthodontic problems to be diagnosed and treated. Clinical case: an eight-year-old mixed race female patient, who attended the orthodontic service at Ormani Arenado Llonch Dentistry Clinic for presenting dental deformity and a history of inheritance, she maintained the Milk Bottle habit until the three years of age, where lingual thrust still persists, molar relationship of mesiocclusion, a poor relationship of the bony bases with an inverted bilabial closure were also observed. A therapeutic modality that included a clinical and cephalometric diagnosis was chosen with the subsequent orthodontic treatment, using a facial mask for the correction of the occlusion anomalies. Conclusions: a clinical case of class III malocclusion was presented at the beginning of the permanent dentition and with the use of facial mask the function was achieved, along with the restoration of aesthetics.Introducción: la maloclusión clase III dentoesquelética se ha considerado a lo largo de la historia como uno de los maloclusiones más llamativas debido a la deformidad facial que puede ocasionar. Todo esto hace que sea considerada uno de los problemas de ortodoncia más complejos y difíciles de diagnosticar y tratar. Caso clínico: paciente de ocho años de edad, mestiza, que acude a la consulta de Ortodoncia de la Clínica Estomatológica "Ormani Arenado LLonch" por presentar deformidad dentaria en cuya anamnesis se recogen antecedentes de herencia, mantuvo hábito de biberón hasta los tres años y actualmente presenta empuje lingual, relación molar de mesioclusión, una mala relación de sus bases óseas con un cierre bilabial invertido. Se optó por una modalidad terapéutica que incluyó un diagnóstico clínico y cefalométrico con el posterior tratamiento ortodóncico, apoyándonos en la máscara facial para la corrección de las anomalías de la oclusión. Conclusiones: se presentó un caso clínico de maloclusión clase III a inicios de la dentición permanente y con la aparatología empleada se logró un resalte funcional, así como el restablecimiento de la estética

Maloclusión clase III tratada con retropropulsor-estimulador 2
Universidad de Ciencias Médicas de Pinar del Río, 2016Co-Authors: Rezk Díaz Anay, Martínez Vergara Yisbel, Martínez Rodríguez Mallén, Bioti Torres, Analina MercedesAbstract:Introduction: a class III malocclusion is a complex disorder which presents alterations in the three planes of the oral space, it results in several craniofacial expressions with a wide range of dental and skeletal disorders. That is why, it is considered one of the most complex orthodontic problems and most difficult to diagnose and treat.Case report: a 12-year-old, female, black patient with a health history, attending at Ormani Arenado Llonch Dental Clinic, Orthodontic Office, presented a front inverted occlusion with no previous history of inheritance, who kept the habit of Milk-Bottle until 9 years and currently has tongue thrust, a front crossbite of 2 mm, molar ratio of mesial-occlusion, a bad relationship on her bony bases with a reversed bilabial closure. A therapeutic modality that included a clinical and cephalometric diagnosis with subsequent orthodontic treatment was chosen, relying on the functional appliance of retro-propulsion stimulator 2 for correcting this malocclusion.Conclusions: a case of a class III malocclusion was presented in the early stages of permanent dentition using orthodontic appliances, achieving good functional results as well as the restoration of aesthetics.Introducción: la maloclusión clase III es una alteración compleja, que presenta alteraciones en los tres planos del espacio, resultando en varias expresiones craneofaciales con un amplio rango de alteraciones dentales y esqueléticas. Todo esto hace que sea considerada uno de los problemas de ortodoncia más complejos y difíciles de diagnosticar y tratar.Caso clínico: se presenta el caso clínico de una paciente de 12 años de edad, raza negra, con antecedentes de salud que acude a la consulta de Ortodoncia de la Clínica Estomatológica “Ormani Arenado LLonch” por presentar oclusión invertida anterior en cuya anamnesis no se recogen antecedentes de herencia, mantuvo hábito de biberón hasta los 9 años y actualmente presenta empuje lingual, mordida cruzada anterior de 2 mm, relación molar de mesioclusión, una mala relación de sus bases óseas con un cierre bilabial invertido.

post consumer contamination in high density polyethylene hdpe Milk Bottles and the design of a Bottle to Bottle recycling process
Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2005Co-Authors: Frank WelleAbstract:Six hundred conventional recycled HDPE flake samples, which were recollected and sorted in the UK, were screened for post-consumer contamination levels. Each analysed sample consisted of 40-50 individual flakes so that the amount of analysed individual containers was in the range 24,000-30,000 post-consumer Milk Bottles. Predominant contaminants in hot-washed flake samples were unsaturated oligomers, which can be also be found in virgin high-density polyethylene (HDPE) pellet samples used for Milk Bottle production. In addition, the flavour compound limonene, the degradation product of antioxidant additives di-tert-butylphenol and low amounts of saturated oligomers were found in higher concentrations in the post-consumer samples in comparison with virgin HDPE. However, the overall concentrations in post-consumer recycled samples were similar to or lower than concentration ranges in comparison with virgin HDPE. Contamination with other HDPE untypical compounds was rare and was in most cases related to non-Milk Bottles, which are <2.1% of the input material of the recycling process. The maximum concentration found in one sample of 1 g was estimated as 130 mg kg(-1), which corresponds to a contamination of 5200-6500 mg kg(-1) in the individual Bottle. The recycling process investigated was based on an efficient sorting process, a hot-washing of the ground Bottles, and a further deep-cleaning of the flakes with high temperatures and vacuum. Based on the fact that the contamination levels of post-consumer flake samples are similar to virgin HDPE and on the high cleaning efficiency of the super-clean recycling process especially for highly volatile compounds, the recycling process investigated is suitable for recycled post-consumer HDPE Bottles for direct food-contact applications. However, hand-picking after automatically sorting is recommended to decrease the amount of non-Milk Bottles. The conclusions for suitability are valid, provided that the migration testing of recyclate contains Milk Bottles up to 100% and that both shelf-life testing and sensorial testing of the products are successful, which are topics of further investigations.
