This paper applies the peridynamic continuum mechanics theory on a new type of material known as harmonic-structured materials. Using the Peridigm software, rapid uniaxial elongation is simulated on a peridynamic model of a thin bimodal harmonic-structured metal sheet. Mechanical wave initiation, propagation, and reflection, as well as fracture initiation and propagation are successfully simulated

While the design of goods and services is undeniably important in cultivating customer engagement (CE) with industrial innovations, the theoretical interface of industrial design, innovation, and CE remains nebulous, exposing an important literature-based gap. Relatedly, while the literature has focused on the firm as the focal designing stakeholder, further knowledge building is needed regarding

Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. Slutsatser 1. OfiltreratThe aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the

A growing number of inherited disorders causing severe and progressive neurological deficits are linked to peroxisomal dysfunction. More than 15 peroxisomal diseases with neurological manifestations and some of them with dysmorphic features are identified. The diseases are classified into three groups depending on some similarities in the pathophysiology of the diseases within each group: defectiv

In the concluding chapter, we outline the major findings from the eleven book chapters by connecting them to one another. We come back to the triadic delegation and accountability relationship between candidates, voters and parties that were developed based on principal–agent theory, and emphasise the most relevant findings of this book that inform this triad. The chapter also takes a critical sta

The universally recognised action spectrum for the UV-induced conversion of 7-dehydrocholesterol to previtamin D3 in human skin was published in 1982, and indicates a maximum at about 297 nm with essentially no production above 315 nm. This work represents a milestone in research on vitamin D, but limitations in the original data should be recognised. Various findings have arisen in recent years w

Purpose: This study evaluated postoperative complications of percutaneous nephrolithotomy (PCNL) and the influence of selected factors on the risk of complications using the Clinical Research Office of the Endourological Society (CROES) PCNL Global Study database. Patients and Methods: The CROES PCNL Global Study collected prospective data for consecutive patients who were treated with PCNL at cen

BACKGROUND: Legumes are one of the most common foods causing allergic reactions in children and adults. Cross-reacting antibodies are frequently demonstrated in this family but the real clinical cross-reactivity is uncommon. OBJECTIVE: To report a case of lupine-induced anaphylaxis and to elucidate in vivo and in vitro cross-reactivity with some legumes. METHODS: Skin prick test (SPT) with some le

The UV photodissociation (<5 eV) of diiodomethane (CH(2)l(2)) is investigated by spin-orbit ab inito calculations. The experimentally observed photodissociation channels in the gas and condensed phases are clearly assigned by multi-state second-order multiconfigurational perturbation theory in conjunction with spin-orbit interaction through complete active space-state interaction potential energy

Indapamide is a nontiazidic sulfonamide diuretic which has not been previously reported as a cause of fixed drug eruption. We describe a patient who experienced several episodes of fixed drug eruption during treatment with indapamide. The diagnosis was confirmed by positive controlled oral challenge test. The possible existence of cross-reactivity with other sulfonamide derivatives was investigate

Development of artificial neural network (ANN) models using real plant data for the prediction of fresh steam properties from a brown coal-fired boiler of a Slovenian power plant is reported. Input parameters for this prediction were selected from a large number of available parameters. Initial selection was made on a basis of expert knowledge and previous experience. However, the final set of inp

Neuroendocrine abnormalities are common in Parkinson's disease (PD) and include disruption of melatonin secretion, disturbances of glucose, insulin resistance and bone metabolism, and body weight changes. They have been associated with multiple non-motor symptoms in PD and have important clinical consequences, including therapeutics. Some of the underlying mechanisms have been implicated in the pa
