Możliwości energetycznego wykorzystania biomasy mikroalg
2016
Niniejsze opracowanie przedstawia możliwości zastosowania mikroalg do produkcji biopaliw III generacji - biodiesla, bioetanolu i biowodoru. Opisano parametry - CO2, temperatura, pH, światło i inne - zapewniające optymalne warunki hodowli mikroalg w fotobioreaktorach. Dokonano charakterystyki fotobioreaktorów, pod kątem ich przydatności do hodowli mikroalg na cele energetyczne. Przedstawiono metody termochemicznego i biochemicznego przetwarzania biomasy glonów stosowane do produkcji poszczególnych biopaliw.
Pre-operative leukocytosis: a potential poor prognosis risk factor in cardiac device implantation: a case report
2022
Introduction. Despite the benefits of the implantation of cardiac rhythm management devices cardiac implantable electronic device (CIED) infection is an emerging problem New debate emerged about the unclear role of the pre-operative alteration of pro-inflammatory parameters, such as leukocytosis, in the development CIED infection and/or heart failure, and its consequent impact on the timing of ICD implantation/reimplantation. Case report. A 65 years old patient with a history of Diabetes Mellitus (DM) type II, ventricular and supraventricular arrhythmias, chronic myocardial ischemia, heart failure was admitted to hospital.Healthcare workers opted for ICD implantation despite the presence of…
ELECTROCHEMICAL MICROREACTORS FOR SYNTHESIS OF CHEMICALS AND ABATEMENT OF ORGANIC POLLUTTANTS
2014
Electrochemical methods can offer new sustainable routes for both the synthesis of chemicals and the abatement of organic pollutants resistant to biological processes. These methods use a clean reagent, the electron, and very mild operative conditions (ambient temperature and atmospheric pressure) with limited operative costs. However, electrochemical processes present some important disadvantages when performed in conventional reactors. In particular, to achieve reasonable cell voltages when the medium has not an adequate conductivity, one needs adding to the system a supporting electrolyte. This is certainly a main obstacle for a wide application of electrochemical tools. Indeed, adding c…
ABATEMENT OF ACID ORANGE 7 IN WATER BY DIFFERENT ELECTROCHEMICAL APPROACHES
2014
Very large amounts of synthetic dyes are discharged in the environment from industrial effluents [1]. Due to their large-scale production and extensive application, synthetic dyes can cause considerable nonaesthetic pollution and are serious health-risk factors [2]. Dyes are commonly classified from their chromophore group. The majority of these compounds consumed at industrial scale are azo (–N=N–) derivatives that represent more than 50% of the all dyes used in textile industries, although antraquinone, indigoide, triphenylmethyl, xanthene, sulphur and phtalocyanine derivatives are frequently utilized [3]. Since dyes usually present high stability under sunlight and resistance to microbia…
In Vitro Regeneration of
2019
Three caper (Capparis spinosa L.) biotypes grown on the Sicilian island of Salina (38°33′49″ N) were micropropagated to evaluate two different in vitro culture systems: one using the traditional solid medium, and the other based on liquid culture in a PlantForm bioreactor. PlantForm is a temporary immersion system (TIS), a new propagation method in which the shoots undergo temporary immersion in a liquid medium in order to avoid the accumulation of gas through forced ventilation. This study proposes a protocol to improve the efficiency of in vitro propagation of caper plants, while also reducing production costs, because of the elimination of the gelling agent, and manual labor, requiring l…
Bedrock and soil geochemistry influence the content of chemical elements in wild edible mushrooms (Morchella group) from South Italy (Sicily)
2019
Chemical elements in the samples of wild edible mushrooms of the <em>Morchella</em> group collected from different unpolluted Sicilian sites was analyzed by the ICP-MS (method) to detect the content of their minerals and determine whether soil geology and geochemistry can influence the chemical composition in fungi. Results showed that the mushroom samples mainly contained a high concentration of K and P and a wide variety of minor and trace elements (V, Mo, Pb, Ce, Cs, Zr), including heavy metals. Statistical analysis showed that the mushrooms differed in their content of minor and trace elements based on the geological/geographic site of origin. Comparison with other studies s…
A Bayesian Mixed-Methods Analysis of Basic Psychological Needs Satisfaction through Outdoor Learning and Its Influence on Motivational Behavior in Sc…
2017
Research has shown that outdoor educational interventions can lead to students' increased self-regulated motivational behavior. In this study, we searched into the satisfaction of basic psychological needs (BPN), i.e., autonomy support, the learners' experience of competence, and relatedness, both within the peer group and with their teachers, through outdoor learning. From 2014 to 2016, n = 281 students attended “research weeks” at a Student Science Lab in the Alpine National Park Berchtesgaden (Germany). The program is a curriculum-based one-week residential course, centered on a 2-day research expedition. Both before and after the course, students completed a composite questionnaire addr…
Acute heart failure due to giant left atrium: remote ECLS implantation for interhospital transfer and bridging to decision
2018
AbstractBackgroundRemote extracorporeal life support (ECLS) implantation and mobile ECLS are increasingly applied to enable the treatment of patients with refractory heart failure at specialized care centers. Giant left atrium (GLA) is a rare cause but may lead to acute and devastating heart failure.Case reportAcute heart failure that gave rise to a prolonged period of out-of-hospital cardiopulmonary resuscitation in a patient who underwent remote ECLS implantation was found to have resulted from a GLA of impressive dimensions. There having no reasonable option for immediate surgical therapy, the patient was successfully bridged to recovery with a view to subsequent heart transplantation.Co…
Mobile Technology Adoption and the Effects of Cultural Factors
2019
Mobile technologies are an important part of human life in both the personal and professional realms. Many services (banking, news, health, education, etc.) that traditionally offered either face-to-face, telephone, or other conventional platforms and technologies are now establishing services on mobile platforms as well. Mobile gadgets are now also being used by company employees as sales automation tools. The importance of culture in technology adoption and usage has been well-established. The adoption of any technology includes a set of factors that determine if the technology is either accepted or rejected, and the individual strengths of these determining factors may vary greatly, depe…
