Enhanced chain dynamics in loop-sorting-systems by means of layout optimization and a kinematic model of the polygon action
2012
Published version of an article in the journal: Structural and Multidisciplinary Optimization. Also available from the publisher at: http://dx.doi.org/10.1007/s00158-011-0743-7 Poor dynamics owing to polygon action is a known concern in mechanical applications of closed articulated chains. In this paper a kinematic model of the polygon action in large chains of loop-sorting-systems is proposed. Through optimization techniques the chain dynamics is improved by minimizing the polygon action using a parametric model of the track layout as design variables. Three formulations of the kinematic polygon action are tested on an average sized planer tracks layout to find a superior model. Verificati…
The use of in-line quantitative analysis to follow polymer processing
2009
In this work it is presented three applications of real time analysis during extrusion process using an optical device developed by our research group, which applies the concepts of light extinction. Monitoring of polymer blends morphology takes place to infer data concerned to dispersed phase size and concentration. The detector also enables information about melting temperature of polymer during extrusion and the level of viscous heating, and the exfoliation step during processing of a polymer-clay nanocomposite.
Powinności kształcenia językowego w L1 a niektóre aspekty lingwistyki poststrukturalistycznej
2022
The article is a part of the discussion on language education in L1 in a modern school. The vision presented in it is based on poststructuralist linguistic concepts, in which language is perceived in a non-systemic way, giving it a humanistic, anthropological-subjective, and cognitive dimension. The author discusses three good practice proposals as examples that fit into the presented didactic concept: in the first, writing character profiles was considered a story that interprets oneself and the world, in the second dictionary-phraseological exercises were assigned the function of changing the perception of reality, the third is an attempt to create a methodology based on the achievements …
New high-pressure phase and equation of state of Ce2Zr2O8
2012
In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed from high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearly 12 GPa. The ambient-pressure cubic phase of Ce2Zr2O8 transforms to a rhombohedral structure beyond 5 GPa with a feeble distortion in the lattice. Pressure evolution of unit-cell volume showed a change in compressibility above 5 GPa. The unit-cell parameters of the high-pressure rhombohedral phase at 12.1 GPa are ah = 14.6791(3) {\AA}, ch = 17.9421(5) {\AA}, V = 3348.1(1) {\AA}3. The structure relation between the parent cubic (P2_13) and rhombohedral (P3_2) phases were obtained by group-subgroup relations. All t…
Haptic Perception in Extreme Obesity: qEEG Study Focused on Predictive Coding and Body Schema
2020
Haptic perception (HP) is a perceptual modality requiring manual exploration to elaborate the physical characteristics of external stimuli through multisensory integrative cortical pathways. Cortical areas exploit processes of predictive coding that collect sensorial inputs to build and update internal perceptual models. Modifications to the internal representation of the body have been associated with eating disorders. In the light of this, obese subjects were selected as a valid experimental model to explore predictive coding in haptic perception. To this purpose, we performed electroencephalographic (EEG) continuous recordings during a haptic task in normally weighted versus obese subjec…
Skolotāja valoda angļu valodas stundās pozitīvu attiecību veidošanai klasē
2017
Pētījums aplūko kā skolotāju klases valoda palīdz veidot pozitīvas savstarpējās attiecības klasē, jo pozitīvai atmosfērai klasē ir nozīmīga loma svešvalodu apguvē. Aptaujā – pētījumā tika izmantotas šādas datu ieguves metodes: anketas piekto līdz divpadsmito klašu skolēniem, angļu valodas stundu novērošanas pieraksti, intervijas ar angļu valodas skolotājiem. Iegūtie dati atklāj skolēnu viedokli par angļu valodas skolotājiem un angļu valodas stundām, norādot, ka skolotājiem ir nepieciešams vairāk domāt par visu skolēnu iesaistīšanu mācību stundā, skolotāja lietotās valodas sarežģītību un runas ātrumu, kā arī vienādu attieksmi pret visiem skolēniem. Novērojot angļu valodas stundas, autore pie…
The Healthy Body Image intervention and reduction in eating disorder symptomatology and muscle building supplement use in high school students: a stu…
2022
BackgroundMediation analysis is important to test the theoretical framework underpinning an intervention. We therefore aimed to investigate if the healthy body image (HBI) intervention’s effect on eating disorder (ED) symptomatology and use of muscle building supplements was mediated by the change in risk and protective factors for ED development and muscle building supplement use.MethodsThis study used data from the HBI intervention: a cluster randomized controlled universal intervention aiming to promote positive body image and embodiment and reduce the risk for ED development including 30 schools in Norway. A total of 1,713 (37% boys) participants were included in the analyses. Condition…
Sensory Organ Investment Varies with Body Size and Sex in the Butterfly Pieris napi
2021
Simple Summary Pollinating insects rely on a range of senses such as vision, olfaction, gustation, and mechanosensation to utilise, locate, and fly between floral resources. The size of different sensory organs determines their sensitivity and provides an indication of their relative importance—larger organs can enhance sensitivity by increasing the number or size of sensing structures. However, increasing the relative size of an organ would require additional energy for developing and maintaining it. This likely leads to a trade-off between the energy invested into different sensory systems within individuals. To explore how the size of the sensory organs vary with body size in insect poll…
Quali sono le specie arboree a rapido accrescimento per la Sicilia?
2018
A dispetto dell’uso diffuso massiccio della locuzione “specie a rapido accrescimento”, riferita a specie utilizzate per la produzione di biomassa, mancano ad oggi riferimenti certi che servano a definire le suddette specie. Si consideri, inoltre, che la locuzione è utilizzata, oltre che in articoli e testi tecnici, anche in testi che hanno carattere applicativo e/o costituiscono norme di riferimento come, ad esempio, le misure dei Piani di Sviluppo Rurale. Una definizione ormai datata della FAO (1967), riferita ai paesi in via di sviluppo, riporta: “Fast-growing species are considered as those capable of a mean annual increment of at least 10 cubic meters per hectare”. Nel frattempo, da qua…
