Síntese de nanopartículas de óxido de ferro e nanocompósitos com polianilina
Authors: Araújo Ana Cláudia Vaz de 
Published: March 2021

In this work magnetic Fe3O4 nanoparticles were synthesized through the precipitation method from an aqueous ferrous sulfate solution under ultrasound. A 23 factorial design in duplicate was carried out to determine the best synthesis conditions and to obtain the smallest crystallite sizes. Selected conditions were ultrasound frequency of 593 kHz for 40 min in 1.0 mol L-1 NaOH medium. Average crystallite sizes were of the order of 25 nm. The phase obtained was identified by X-ray diffractometry (XRD) as magnetite. Scanning electron microscopy (SEM) showed polydisperse particles with dimensions around 57 nm, while transmission electron microscopy (TEM) revealed average particle diameters around 29 nm, in the same order of magnitude of the crystallite size determined with Scherrer’s equation. These magnetic nanoparticles were used to obtain nanocomposites with polyaniline (PAni). The material was prepared under exposure to ultraviolet light (UV) or under heating, from dispersions of the nanoparticles in an acidic solution of aniline. Unlike other synthetic routes reported elsewhere, this new route does not utilize any additional oxidizing agent. XRD analysis showed the appearance of a second crystalline phase in all the PAni-Fe3O4 composites, which was indexed as goethite. Furthermore, the crystallite size decreases nearly 50 % with the increase in the synthesis time. This size decrease suggests that the nanoparticles are consumed during the synthesis.	Thermogravimetric analysis showed that the amount of polyaniline increases with synthesis time. The nanocomposite electric conductivity was around 10-5 S cm-1, nearly one order of magnitude higher than for pure magnetite. Conductivity varied with the amount of PAni in the system, suggesting that the electric properties of the nanocomposites can be tuned according to their composition. Under an external magnetic field the nanocomposites showed hysteresis behavior at room temperature, characteristic of ferromagnetic materials. Saturation magnetization (MS) for pure magnetite was ~ 74 emu g-1. For the PAni-Fe3O4 nanocomposites, MS ranged from ~ 2 to 70 emu g-1, depending on the synthesis conditions. This suggests that composition can also be used to control the magnetic properties of the material.

Problem tożsamości istoty ludzkiej jako bytu trwającego w czasie
Authors: Dębowski Józef 
Published: March 2021

Drogi dochodzenia do problemu tożsamości ludzkiej istoty są rozmaite. Również jego rozstrzygnięcia są mocno zróżnicowane – dzisiaj bodaj bardziej niż kiedykolwiek. Mimo komplikacji, jakie niosą ze sobą współczesne dynamiczne realia zżycia, nie rezygnujemy jednak z poszukiwań. Dalej wytrwale poszukujemy dobrej odpowiedzi na pytanie: „co to znaczy» byś sobą«?”. Dalej zaprzątają nas warunki konieczne zachowania osobowej tożsamości. Dalej próbujemy określić granice zmian, które jesteśmy w stanie tolerować bez ryzyka utraty tożsamości. Dalej nie jest nam obojętne, kim jesteśmy lub kim się stajemy. W zamieszczonym niżej artykule, inspirowanym m.in. badaniami z zakresu współczesnych neuronauk, szkicuje pewna filozoficzna propozycje zmierzenia się z wyżej wymienionymi pytaniami - propozycje, która co prawda powstała przeszło 60 lat temu, lecz która zarazem nic zgoła nie straciła na aktualności. Przeciwnie, opracowana przez R. Ingardena filozoficzna strategia wydaje się obecnie wyjątkowo skuteczna. Także w odniesieniu do problematyki tożsamości, także w czasach wszechobecnego funkcjonalizmu.
Formal power and real authority: the involvement of governance norms or principles
Authors: Picavet Emmanuel 
Published: March 2021

In several avenues of contemporary research, much attention is devoted to the contrast between the real authority of institution and their formal power, in the analysis of institutional funtionings; also in the study of the relationships between institutions on the one hand, rules, principles or norms on the other hand. Such a contrast appears to be based on familiar observations: the capacity of institutions to get their preferred outcomes (their so-called „real authority”) is sometimes loosely connected with the hierarchical prerogatives of the considered institutions (their „formal power”). More particularly, current studies of the „migration authority” bring out possible shitts in real authority while there is no changein the formal structure of power. This article will partly consist in the explanation of recent results of common reaserch in project „Delicom”, in which a formal treatment of the distinction has been put foward. This approach will be set against the background of recent contributions in political science or economics (in the works of Ph. Aghion and J. Tirole, J. Backhaus, L. Thorlakson). The revelance of the problematic for the study of competence delegation among institutions will be stressed all along.
A need for Metaphysics of Respect for Humans
Authors: Omielczenko Nikolaj 
Published: March 2021

Niniejsza praca poświęcona jest pozycji człowieka we współczesnym świecie. Autor wychodzi do przedstawienia status quo Milana Kundery. Następnie omawia takie zagadnienia jak ,,wolność jest czynnikiem bezpieczeństwa”, ,,własność i wolność”. Jego zdaniem wolność i bezpieczeństwo nie mogą być przeciwstawiane. Pewne bezpieczeństwo nie może być rozumiane z perspektywy praw człowieka i wolności. Uważa on, że wolność jest atrybutem istoty ludzkiej, a humanizm entelechią ludzkiej natury. Porównuje liberalne hasło ,,własność jest wolnością” z definicją ekonomiczną ,,płaca jest tożsama z własnością prywatną”.
Autor analizuje Fabrykę os Iaina Banksa oraz Pachnidło Patricka Suskinda. Uważa, że obydwie powieści opowiadają o braku miłości, a cieszą się taką popularnością, ponieważ niewielu ludzi potrafi kochać, ale każdy chce wiedzieć, co to znaczy kochać i być kochanym. Powieści na swój sposób zaświadczają, że bez miłości zanika osobowość, że to miłość czyni człowieka ludzkim.
Autor utrzymuje, że pojmowanie człowieka jako istoty stwarzającej sprawia, że czynienie ostatecznych sądów o nim jest wysoce problematyczne. Poza czysto teoretycznymi ujęciami, morderstwo, samobójtwo, kara śmierci, dożywocie, eutanazja, wojna, ludobójstwo oraz inne metody mogą się do nich zaliczać. Takie działania ,,kategoryczne” są na porządku dziennym we współczesnym świecie. Z tego powodu zasadniczo eleganckie, spekulatywne usprawiedliwienie stoi za brutalną przemocą fizyczną. Jednocześnie autor proponuje metafizyczny argument przeciwko karze śmierci. Jego zdaniem ostateczne wyroki na istotach ludzkich są niedopuszczalne.

Introduction: Topical investigations have demonstrated that oxidative stress and inflammation play key roles in biological aging and determine incidence and course of age-related diseases. Lifestyle and environmental factors hugely impact epigenetic regulation and DNA stability with telomere attrition and epigenetic instability providing a potential record of the cumulative burden of endogenous and exogenous oxidative noxae. Certain physiologically active plant components exhibit antioxidative activities affecting epigenetic regulation of inflammation response and DNA repair.Methods: Against this background, the present study investigated green tea polyphenol epigallocatechin gallate (EGCG) in the context of telomere regulation in Caco-2 colorectal adenocarcinoma cells vs. ES-1 primary skin fibroblasts. Cell lines were treated with 20 and 200 µM EGCG for 36, 72 and 144 hours, respectively. Telomerase activity, relative telomere length as well as methylation status of hTERT and c-Myc from different culture conditions were assessed. Malondialdehyde (MDA) served as a surrogate marker of potential pro-oxidative effects of EGCG in a physiologically relevant tissue model.Results: EGCG incubation was associated with telomere shortening and decreased telomerase activity in Caco-2 cells, and relatively longer telomeres along with increased methylation of six 5'—C—phosphate—G—3' (CpG) sites in the promoter region of human Telomerase Reverse Transcriptase (hTERT) in fibroblasts. At low concentrations, EGCG significantly decreased oxidative damage to lipids in Caco-2 cells and attenuated H2O2 induced oxidation at higher concentrations.Conclusion: These results suggest differential EGCG-mediated telomeric modulation in cancer vs. primary cells and a specific antioxidant activity of EGCG against oxidative damage to lipids in abnormal cells.Keywords: Caco-2, epigallocatechin gallate, telomeres, hTERT, DNA methylation, telomerase, oxidative stress, malondialdehyde
Servant leadership and nurses’ upward voice behavior in an Egyptian hospital: Does prosocial motivation matter?
Authors: Abdelmotaleb Moustafa , Metwally Abdelmoneim , Saha Sudhir K. 
Published: March 2021

BACKGROUND: Servant leadership can be viewed as a leadership theory that stresses personal integrity and focuses on protecting and promoting the interests of others. OBJECTIVE: This article investigates whether the relationship between servant leadership and nurses’ upward voice behavior in an Egyptian hospital is contingent on prosocial motivation. Invoking substitutes for leadership theory, we propose that the relationship between servant leadership and nurses’ upward voice will be attenuated when nurses have a strong desire to protect and promote the well-being of others. METHODS: Using a sample of 341 nurses working in a large governmental hospital in Egypt, this proposition was tested using PROCESS Macro for SPSS. RESULTS: The results revealed that the relationship between servant leadership and nurses’ upward voice was stronger for those lower in prosocial motivation than for those higher in prosocial motivation. CONCLUSION: These results were explained through communal impulsion which adds a new insight into Greenleaf’s theory of servant leadership. Overall, the results of the study shed new light on the conditions through which servant leadership enhances upward voice behavior in an Egyptian hospital.

Published: March 2021

BACKGROUND: Manual wheelchair users are at a high risk of repetitive strain injuries, carpal tunnel syndrome, and rotator cuff tears due to propelling their wheelchair for mobility. Rolling resistance (RR) is one of the key forces that leads to increased propulsion forces and risk of injuries. OBJECTIVE: To better understand the factors contributing to RR, we iteratively designed, developed, and validated a drum-based testing machine and test method. METHODS: As part of the validation of the system, we tested and compared 4 manual wheelchair wheels under a range of conditions including camber, toe in/out, tire pressure, surfaces, and speed. A treadmill was employed to simulate flat ground RR. RESULTS: A machine was effectively designed, developed, and tested to measure RR. Tire type, surfaces, and toe were found to be the largest contributors to RR. Comparison of the drum-based system to flat ground revealed that an offset can be used to calculate overground RR from drum measurements. CONCLUSIONS: Ongoing work includes performing a comprehensive analysis of the degree to which each factor contributes to RR of commonly used casters and rear-wheels so that the wheelchair sector can work to reduce RR and the associated risk of repetitive strain injuries.

Published: March 2021

BACKGROUND: Young adults with an intellectual disability require transportation to participate in work and leisure, however reports on specific public transportation training programs, use of assistive technology supports, and outcomes are limited. OBJECTIVE: This pilot study was designed to explore if a transportation training program which utilized technology aids decreased the amount travel assistance required. A secondary objective was to observe and describe the specific assistive technology utilized while traveling within the community. METHODS: Eight individualized training sessions were administered within the community with the integration of technology aids and travel skill training through a facilitated learning model. The Pre & Post Travel Training Test was administered pre-test and post-test. RESULTS: The paired [Formula: see text] test ([Formula: see text] 10) revealed a significant increase in scores upon post-test ([Formula: see text] 0.00011), indicating a decrease in assistance required for travel. The most preferred technology aid was individualized, printed Google Maps directions (60%) followed by smartphone Apps (40%) and visual social stories (40%). CONCLUSIONS: All participants increased independence in public transportation travel skills. Ample opportunity to trial low to high technology aids should be considered. Through this initial pilot, possible greater availability of access to work and community opportunities may result after community-based transportation training.
Chronic pontine strokes: Diffusion tensor imaging of corticospinal tract indicates the prognosis in terms of motor outcome
Authors: Xue Qian , Yang Xiao-Han , Teng Gao-Jun , Hu Shu-Dong 
Published: March 2021

OBJECTIVE: To investigate relationship between the diffusion indexes of corticospinal tract (CST) and the neurological motor outcomes in chronic pontine stroke patients. METHODS: Diffusion tensor imaging (DTI) is performed in 27 patients with chronic pontine stroke. Fractional anisotropy (FA) values along the CST area, the track number, and the CST length are measured. Neurological and motor outcomes are evaluated based on Fugl-meyer (FM), National Institutes of Health Stroke Scale (NIHSS), Barthel index (BI), and modified Rankin scale (mRS) scores. The relationships between FA ratios (rFAs) in the CST of stroke subjects and their clinical motor scores are analyzed through Spearman’s correlation analysis. Then, diffusion tensor tractography (DTT) is performed to show the injury degree of CST. RESULTS: First, FA values are decreased in the infarct area, cerebral peduncle, posterior limb of the internal capsule, and precentral gyrus compared with those in the contralateral side. The number of CST is decreased in the ipsilateral side of the infarct. Second, rFAs in the cerebral peduncle, posterior limb of the internal capsule, and CST rnum correlate positively with FM scores ( r = 0.824, 0.672, 0.651, p < 0.001) and negatively with mRS scores ( r = –0.835, –0.604, –0.645, p≤0.001). Third, the injury degree of CST correlates negatively with FM scores ( r = –0.627, p < 0.001). CONCLUSIONS: The study demonstrates that rFAs in the cerebral peduncle, posterior limb of the internal capsule, and CST rnum associate with motor outcome, suggesting that DTI may be applicable for outcome evaluation.
