Comparison of oxidoreductive enzyme activities in three coal tar creosote-contaminated soils
2019
This study used laboratory experiments to compare the effects of coal tar creosote on the activity of oxidoreductive enzymes in sandy loam, loamy sand and sandy clay loam soils. Different amounts of coal tar creosote were added to soil samples as follows: 0 (control), 2, 10 or 50 g kg–1 dry matter. The activity of soil dehydrogenases (DHAs), o-diphenol oxidase (o-DPO), catalase (CAT), nitrate reductase (NR) and peroxidases (POX) was determined. Contamination of soil with coal tar creosote affected oxidoreductase activity. Oxidoreductive enzyme activity following soil contamination with coal tar creosote was in the following order: DHAs > CAT > NR > POX > o-DPO in…
Direct Visualization of Molecule Deprotonation on an Insulating Surface
2012
Elucidating molecular-scale details of basic reaction steps on surfaces is decisive for a fundamental understanding of molecular reactivity within many fields, including catalysis and on-surface synthesis. Here, the deprotonation of 2,5-dihydroxybenzoic acid (DHBA) deposited onto calcite (101;4) held at room temperature is followed in situ by noncontact atomic force microscopy. After deposition, the molecules form two coexisting phases, a transient striped phase and a stable dense phase. A detailed analysis of high-resolution noncontact atomic force microscopy images indicates the transient striped phase being a bulk-like phase, which requires hydrogen bonds between the carboxylic acid moie…
Antineoplastic dosing in overweight and obese cancer patients: an Associazione Italiana Oncologia Medica (AIOM)/Associazione Medici Diabetologi (AMD)…
2021
Most anticancer molecules are administered in body-size-based dosing schedules, bringing up unsolved issues regarding pharmacokinetic data in heavy patients. The worldwide spread of obesity has not been matched by improved methods and strategies for tailored drug dosage in this population. The weight or body surface area (BSA)-based approaches may fail to fully reflect the complexity of the anthropometric features besides obesity in cancer patients suffering from sarcopenia. Likewise, there is a lack of pharmacokinetic data on obese patients for the majority of chemotherapeutic agents as well as for new target drugs and immunotherapy. Therefore, although the available findings point to the …
Estudio de la eficacia de la plicatura del tendón cantal lateral con anclaje en Y en el síndrome del ojo seco evaporativo
2018
INTRODUCCIÓN El síndrome de ojo seco (SOS) es una patología muy prevalente que afecta a la calidad de vida de los pacientes. El manejo terapéutico del SOS es complejo y varía en función del subtipo de SOS que se esté tratando. No se ha demostrado hasta el momento ninguna técnica quirúrgica que cure aquellos SOS por malposición palpebral de causa intrínseca. HIPÓTESIS, MATERIAL Y MÉTODOS La hipótesis del estudio es que la plicatura del tendón cantal lateral con anclaje en Y es eficaz en el tratamiento del SOS evaporativo de causa intrínseca. Se ha realizado un estudio prospectivo de casos y controles en el que se han reclutado en el periodo de tiempo existente entre noviembre de 2016 y novie…
The effects of microwave radiation generated by mobile phones on the tear film
2021
Abstract Electromagnetic radiation (ER) emitted by mobile phones and other modern devices has potentially harmful effects on ocular tissue. Their effects on the eye surface and tear film are little known so far. The aim of this paper was to investigate the effects of ER emitted by the phone mobile on the tear film. For this study, we selected a total of 50 subjects, young, healthy, without chronic treatment, who are not contact lens wearers and who have no history of ophthalmic surgery. Schirmer I test, tear pH and tear ferning test (TFT) were performed on all subjects before (“-pre”) being exposed to ER emitted by the mobile phone and after (“-post”) exposure for 5 minutes, the pH and TFT …
Increasing Yield and Antioxidative Performance of Litchi Pericarp Procyanidins in Baked Food by Ultrasound-Assisted Extraction Coupled with Enzymatic…
2018
Extraction with organic solvents is a traditional method to isolate bioactive compounds, which is energy-wasting and time-consuming. Therefore, enzyme and ultrasound treatments were combined to assist the extraction of oligomeric procyanidins from litchi pericarp (LPOPC), as an innovative approach to replace conventional extraction methods. Under optimum conditions (enzyme concentration 0.12 mg/mL, ultrasonic power 300 W, ultrasonic time 80 min, and liquid/solid ratio 10 mL/g), the yield of LPOPC could be improved up to 13.5%. HPLC analysis indicated that the oligomeric procyanidins (OPC) content of LPOPC from proposed extraction was up to 89.6%, mainly including (&minus
An Experiment with Facebook as an Advertising Channel for Books and Audiobooks
2016
The paper addresses the problem of using social media to promote innovative products available in online stores. Motivated by the fast development of the audiobook market, on the one hand, and the efficiency of social media marketing, on the other hand, we conducted an experiment with a marketing campaign of books and audiobooks on the most popular social networking site, Facebook, and discussed it in the paper. The goal of the experiment was exploring possible differences in FB users’ reaction to FB advertisements of traditional books and audiobooks. The experiment was implemented by using a real Facebook fanpage of a Polish publishing house having its own online bookstore. Results show so…
Sosiaalisen median käyttö eurooppalaisissa oopperataloissa
2011
Tutkimuksessa selvitettiin sosiaalisen median palveluiden suosiota eurooppalaisten oopperatalojen keskuudessa. Tutkimuksessa tarkasteltiin myös sosiaalisen median palvelun Facebookin käyttöä sekä oopperatalojen Facebookissa jakamien viestien sisältöjä ja niiden sopivuutta markkinointiviestinnän kommunikaatiotekniikoihin. Työn tavoitteena oli myös selvittää ilmiön tämän hetkinen tilanne sekä antaa kuva siitä, mihin suuntaan kehitys on menossa. Tutkimusongelmaa lähestyttiin niin määrällisesti kuin laadullisesti. Tutkimusta varten kerättiin Internetistä numeerista aineistoa 23 oopperatalon käyttämistä sosiaalisen median palveluista kolmena eri ajankohtana, jotta voitiin osoittaa ilmiön kehityk…

Critical issues and future prospects of the secondary substation in smart grid context
2014
This paper is focused on the new role of the secondary substation in the smart grids context. This innovative view has been proposed and developed in the framework of two Research Projects: NewCabELARC Project and Reipersei Project. The latter provides a concrete and comprehensive low cost solutions for the smart grid monitoring and control, allowing the real diffusion and integration of Distributed Generation and the full exploitation of Renewable Energy Sources. In this field, this paper shows how the secondary substation (SS) takes the role of smart transducer node where innovative devices can be located, collecting the measurement data coming from the field devices (power and energy met…
