EFFECT OF SHAPE ON POTATO AND CAULIFLOWER SHRINKAGE DURING DRYING
2000
ABSTRACT Shrinkage of potato cubes, parallelepipeds and cylinders was addressed during drying. A basic methodology by using image analysis was set-up in order to measure and monitor geometrical changes along the drying process. Both measurements by image analysis and directly with a calliper were carried out. Results from both methods showed a good agreement with no bias. Particle shape was found to influence shrinkage in a different way according to the axis. In fact the larger dimension shrinks less than the shorter one. This could be linked to the influence of the core drying in shrinkage. Experiments were also carried out for cauliflower stems. The difference in shrinkage between direct…
Adult-onset Still's disease: an Italian multicentre retrospective observational study of manifestations and treatments in 245 patients
2016
Adult-onset Still’s disease (AOSD) is a systemic inflammatory condition of unknown aetiology characterized by typical episodes of spiking fever, evanescent rash, arthralgia, leukocytosis and hyperferritinemia. Given the lack of data in Italian series, we promote a multicentric data collection to characterize the clinical phenotype of Italian patients with AOSD. Data from 245 subjects diagnosed with AOSD were collected by 15 centres between March and May 2013. The diagnosis was made following Yamaguchi’s criteria. Data regarding clinical manifestations, laboratory features, disease course and treatments were reported and compared with those presented in other published series of different et…
Effect of total knee replacement surgery and postoperative 12 month home exercise program on gait parameters
2017
Abstract Objective To evaluate the effects of surgery and a postoperative progressive home exercise program on gait parameters among individuals operated with total knee arthroplasty. Design Single blinded randomized controlled trial. Subjects 108 patients (84 females, 24 males, mean age 69 years). Interventions Patients were equally randomized into an exercise group (EG) and control group (CG). The 12-months progressive home exercise program starting two months postoperatively was compared to usual care. Methods Gait analysis was performed using the Gaitrite electronic walkway system. In addition, knee extension and flexion strength were measured by a dynamometer preoperatively, and pain o…
Innovation and Entrepreneurial Ecosystems: Structure, Boundaries, and Dynamics
2019
Recognizing the broader dimensions of entrepreneurial and innovation activities, holistic and inclusive networked approaches pave the way to co-creation activities that are essential for achieving sustainability in food systems. Recent studies have started to deepen what are the critical enablers for creating thriving entrepreneurial and innovation ecosystems. Networks that include firms, institutions, and several other relevant stakeholders in knowledge spillovers enable to produce more social and economic value through co-creation processes. However, due to the unique complexity within ecosystems, there is no standardized framework or strategy to develop entrepreneurial or innovation ecos…
Indoor air pesticide in dwellings of breastfeeding mothers of the Valencian Region (Spain): Levels, exposure and risk assessment
2021
This study assessed the inhalation risk associated with indoor pesticide concentrations in the dwellings of 41 lactating mothers living in the Valencian Region, Spain, who were participants in the BETTERMILK project. Twenty-eight substances were investigated, including pyrethroid (PYRs), organophosphate (OPPs), and organochlorine (OCPs) pesticides. Bifenthrin, cypermethrin, lambda-cyhalothrin, malathion, permethrin and pyrimethanil were detected with frequencies ranging from 2% (malathion) to 80% (cypermethrin), and with an arithmetic mean concentration ranging from 4.1 ng m(-3) (bifenthrin) to 12.1 ng m-(3) (cypermethrin). The indoor air analysis was combined with several surveys to assess…
Differential electrophysiologic and inotropic effects of phenylephrine in atrial and ventricular heart muscle preparations from rats.
1991
Stimulation of alpha 1-adrenoceptors evokes a different pattern of inotropic responses in atrial and ventricular heart muscle preparations from rats. The inotropic effects are accompanied by different changes in membrane potential. In an attempt to clarify the question whether or to which extent these events are causally related, the effects of phenylephrine on force of contraction, transmembrane potential, Ca2+ current (ICa) and K+ currents were comparatively studied in either tissue. In atrial preparations, phenylephrine 10 mumol/l caused an increase in force of contraction, a marked prolongation of the action potential duration and a depolarization of the membrane at rest. In the ventric…
Catecholamine release in human skin--a microdialysis study.
2003
Dermal microdialysis might be a promising tool to investigate properties of sympathetic neurons in the skin as investigation of peripheral noradrenergic neurons in humans usually relies on highly variable vasoconstrictor reflexes or on indirect measurements like skin temperature recordings. To evaluate this technique, 21 experiments were performed in 15 healthy subjects with four intracutaneous microdialysis fibers (diameter, 200 microm; cutoff, 5 kDa) at hands or feet. After 60 min, saline perfusion tyramine at concentrations of 0.195 to 200 microg/ml was applied for 15 min followed by a 15-min saline perfusion again. Catecholamine concentrations were detected through high-performance liqu…
Étude typologique, technologique et culturelle de la céramique du Petit-Paulmy à Abilly (Indre-et-Loire)
2009
Anhand einer qualitativen und quantitativen Studie wurden die minimale und die maximale Anzahl der dem Endneolithikum zugeordneten Keramikindividuen ermittelt. Der Corpus umfasst drei typologische und technische Gruppen, die drei chronologischen und kulturellen Phasen entsprechen. Eine Quantifizierung der unterschiedlichen Formen vermittelt ein Bild des endneolithischen Keramikrepertoires des Fundplatzes. Der für die Herstellung der Keramik benutzte Ton ist lokaler Herkunft. Es existiert eine Korrelation zwischen der Dicke der Wandung, der Form der Gefäße und den unterschiedlichen Herstellungstechniken (Glättung, Schaben, Schlagen, Kieselglättung). Die Gefäße der drei Hauptformen wurden in …
The multiple roles of national exams in the certification, governing and support of learning and instruction in Norwegian secondary education.
2018
Hvilke roller har eksamen i norsk grunnopplaering? I Forskrift til opplaeringslova framgar det blant annet at eksamenskarakteren skal fastsette kompetansen til eleven ved slutten av opplaeringen i faget. Denne artikkelen viser imidlertid at policydokumenter og policyutviklere har en rekke forventninger til hva man skal oppna ved a ha eksamen og hva man skal kunne benytte eksamensresultater til. I et samspill mellom teori og empiri identifiser artikkelen tre roller for vurdering: a sertifisere, styre og stotte laering og undervisning. Dette begrepsapparatet brukes til a analysere bade eksamens formelt definerte formal, og tilsiktede og utilsiktede funksjoner ved eksamenssystemet. Artikkelen …
Generalization of thermodynamics allowing negentropic entanglement and a model for conscious information processing
2011
Costa de Beauregard considers a model for information processing by a computer based on an analogy with Carnot's heat engine. I am grateful for Stephen Paul King for bringing this article to my attention in Time discussion group and also for inspiring discussions which also led to the birth of this section. As such the model Beauregard for computer does not look convincing as a model for what happens in biological information processing. Combined with TGD based vision about living matter, the model however inspires a model for how conscious information is generated and how the second law of thermodynamics must be modified in TGD framework. The basic formulas of thermodynamics remain as such…
