description: Background: Antiretroviral Therapy(ART) remarkably reduced HIV-1 infection-related mortality in children. The efficacy and safety of different ART regimen in pediatric age groups remained issues of debates and available evidence were scarce especially among children taking the of one the two prototypes (NVP or EFV) Non-Nucleoside Reverse Transcriptase Inhibitor(NNRTI) as backbone of ART regimen. Therefore, the objective of this study was to compare clinical, immunological and virological responses of zidovudine-lamivudinenevirapine (AZT+3TC+ NVP) versus zidovudine-lamivudine-efavirenz (AZT+3TC+EFV) ART regimen among HIV-1 infected children. Methods: A retrospective cross-sectional study was done by reviewing medical records of the patients to evaluate clinical, immunological and virological outcomes of NVP+AZT+3TC versus EFV+AZT+3TC ART regimen among HIV-1 infected children. Data were entered into Epi-info version 7.2.2 for clean up and exported to SPSS version 17 for analysis. Paired and Independent t-tests were used to compare the CD4 cell count, weight and virologic level at six months with corresponding baseline value; and the mean weight, CD4 gain and viral suppression across the two ART regimens at six months of ART respectively. Results: Medical records of 122 patients from NVP-based regimen and 61 patients from EFV group were reviewed. After six months of NVP+AZT+3TC treatment, the mean CD4 cell count difference from baseline was 215(95% CI, 175.414-245.613, p<0.001). From EFV+AZT+3TC group, the mean CD4 cell count difference from baseline was 205(95% CI 155.404-235.623, p< 0.001). The mean CD4 count difference between the two regimens was comparable (p 0.145). Similarly, optimal viral suppression was achieved in 82% (100/122) of NVP+AZT+3TC regimen and 83% (44/61) of EFV+AZT+3TC regimen which was still comparable across the two groups. Conclusion: There was no difference in clinical, immunological and virological outcomes among patients taking NVP+AZT+3TC or EFV+AZT+3TC ART regimen.

description: Background: In Ethiopia, medicinal plants have been used to treat different diseases, including malaria, for many centuries. People living in rural areas are especially noted for their use of medicinal plants as a major component of their health care. This study aimed to study treatment-seeking and prioritize plants/plant recipes as anti-malarials, in Dembia district, one of the malarious districts in Northwest Ethiopia. Methods: Parents of children aged under 5 years who had had a recent episode of fever were interviewed retrospectively about their child’s treatment and self-reported outcome. Treatments and subsequent clinical outcomes were analysed using Fisher’s exact test to elicit whether there were statistically significant correlations between them. Results and discussion: Of 447 children with malaria-like symptoms, only 30% took the recommended first-line treatment (ACT) (all of whom were cured), and 47% took chloroquine (85% cured). Ninety-nine (22.2%) had used medicinal plants as their first-choice treatment. Allium sativum (Liliaceae), Justicia schimperiana (Acanthaceae), Buddleja polystachya (Scrophulariaceae) and Phytolacca dodecandra (Phytolaccaceae) were the most frequently used. Justicia schimperiana was the one associated with the best clinical outcomes (69% self-reported cure rate). However, the difference in clinical outcomes between the plants was not statistically significant. Conclusion: In this study, only 30% of children took the recommended first-line treatment. 22% of children with presumed malaria were first treated with herbal medicines. The most commonly used herbal medicine was garlic, but J. schimperiana was associated with the highest reported cure rate of the plants. Further research is warranted to investigate its anti-malarial properties.

description: We develop a formalism for computing inclusive production cross sections of heavy quarkonia based on the nonrelativistic QCD and the potential nonrelativistic QCD effective field theories. Our formalism applies to strongly coupled quarkonia, which include excited charmonium and bottomonium states. Analogously to heavy quarkonium decay processes, we express nonrelativistic QCD long-distance matrix elements in terms of quarkonium wavefunctions at the origin and universal gluonic correlators. Our expressions for the long-distance matrix elements are valid up to corrections of order $1/N_c^2$. These expressions enhance the predictive power of the nonrelativistic effective field theory approach to inclusive production processes by reducing the number of nonperturbative unknowns, and make possible first-principle determinations of long-distance matrix elements once the gluonic correlators are known. Based on this formalism, we compute the production cross sections of $P$-wave charmonia and bottomonia at the LHC, and find good agreement with measurements.

description: Wide-field survey instruments are used to efficiently observe large regions of the sky. To achieve the necessary field of view, and to provide a higher signal-to-noise ratio for faint sources, many modern instruments are undersampled. However, precision photometry with undersampled imagers requires a detailed understanding of the sensitivity variations on a scale much smaller than a pixel. To address this, a near-infrared spot projection system has been developed to precisely characterize near-infrared focal plane arrays and to study the effect of sub-pixel non uniformity on precision photometry. Measurements of large format near-infrared detectors demonstrate the power of this system for understanding sub-pixel response.

description: In this paper, we investigate the outage performance of an intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA) uplink, in which a group of the surface reflecting elements are configured to boost the signal of one of the user equipments (UEs), while the remaining elements are used to boost the other UE. By approximating the received powers as Gamma random variables, tractable expressions for the outage probability under NOMA interference cancellation are obtained. We evaluate the outage over different splits of the elements and varying pathloss differences between the two UEs. The analysis shows that for small pathloss differences, the split should be chosen such that most of the IRS elements are configured to boost the stronger UE, while for large pathloss differences, it is more beneficial to boost the weaker UE. Finally, we investigate a robust selection of the elements' split under the criterion of minimizing the maximum outage between the two UEs.

description: Ventilator Associated Pneumonia, a preventable infection of the lower respiratory tract, is one of the most frequent and serious nosocomial infections that afflict critically ill patients hospitalized in an Intensive Care Unit environment (ICU) and require mechanical ventilation. This signifies the clinical importance of ascertaining how to diagnose, manage or prevent VAP, resulting in a better quality of care and patient quality of life. However, no global consensus on practices concerning its prevention has been established. The presented study, is a systematic review accompanied by a meta-analysis, about oral care performed in the ICU setting, toward the prevention of a VAP onset. In the introduction, classification of various types of pneumonia are shown and the microbiological mechanisms that cause VAP are inspected, risk factors of VAP, common antibiotic treatments and the differences of microbial occurrences on different types of patients are reported.

Indeed, this implies a violation of the strong equivalence principle (SEP) for ordinary matter and consequent cosmic acceleration in the observable frame as well as variation of the gravitational constant. The consequent DE mechanism build upon the AWE hypothesis (i) does not require a violation of the strong energy condition $p

Adaptive control of sheet caliper on paper machines
Creators: name: Li, Jing
Publisher: name: University of British Columbia
Year: 2009

description: Caliper control is carried out in the calendering process in order to obtain even thickness of the sheet both in machine-direction and cross-direction. To control caliper, the local temperature of the calender rolls is manipulated. The relationship between temperature and caliper is nonlinear as heating and cooling must be represented by different linear processes. Both models feature timevarying parameters. The correlations among actuators across the roll are described in the interaction matrix of the CD model developed from mill data analysis. Generalized Predictive Control (GPC) is applied under system constraints in machine-direction (MD) and cross-machine direction (CD) control. This control algorithm can handle the timevarying parameters, couplings, and variable delays that are present in the caliper control system. The constrained optimal control signals of GPC are obtained by using the Lagrangian multiplier method. The on-line estimator is based upon Recursive Least Squares with Exponential Resetting and Forgetting factors. Simulations show satisfactory performance of constrained GPC in both MD and CD caliper control. The outputs track set-point changes closely and still have small variations even with parameter changes. Load disturbances added in the CD control system are rejected very well.

description: ATP binding cassette (ABC) transporters form a special famil of membrane proteins, characterized by homologous ATP - binding, and large, multispanningtransmembrane domains. Several members of this family are primary active transporters, which signi ficantly modulate the absorption, metabolism, cellular effectivity and toxicity of pharmacological agents. ABC transporters can transport a wide variety of substrates across biological membranes in an energy - dependent manner. Many ABC transporters such as P - glycoprotein (P - gp), multidrug resistance - associated protein 1 (MRP1) and breast cancer resistance protein (BCRP) are highly expressed in bronchial epithelium. This review provides a general overview of the human ABC transporters, their expression, local ization and basic mechani sm of action in a brief manner.

description: Natural Language Video Localization (NLVL) aims to locate a target moment from an untrimmed video that semantically corresponds to a text query. Existing approaches mainly solve the NLVL problem from the perspective of computer vision by formulating it as ranking, anchor, or regression tasks. These methods suffer from large performance degradation when localizing on long videos. In this work, we address the NLVL from a new perspective, i.e., span-based question answering (QA), by treating the input video as a text passage. We propose a video span localizing network (VSLNet), on top of the standard span-based QA framework (named VSLBase), to address NLVL. VSLNet tackles the differences between NLVL and span-based QA through a simple yet effective query-guided highlighting (QGH) strategy. QGH guides VSLNet to search for the matching video span within a highlighted region. To address the performance degradation on long videos, we further extend VSLNet to VSLNet-L by applying a multi-scale split-and-concatenation strategy. VSLNet-L first splits the untrimmed video into short clip segments; then, it predicts which clip segment contains the target moment and suppresses the importance of other segments. Finally, the clip segments are concatenated, with different confidences, to locate the target moment accurately. Extensive experiments on three benchmark datasets show that the proposed VSLNet and VSLNet-L outperform the state-of-the-art methods; VSLNet-L addresses the issue of performance degradation on long videos. Our study suggests that the span-based QA framework is an effective strategy to solve the NLVL problem.

description: Background: The intrauterine contraceptive device is the most frequently used reversible family planning method in the world. However; its usage is low in many developing countries with a majority of women choosing female sterilization for birth control. Method:A retrospective study design using a quantitative method was used to identify family planning user clients for whom CuT380A was inserted from March 2009-February 2014 GC. A structured check list was employed for data collection. Data was analyzed with Statistical Package for Social Science, version 21. Multivariable logistic regression analysis was done to evaluate the possible association of all variables significant at binary logistic regression analysis. P-value of less than 0.05 in multivariable logistic regression was considered as statistically significant. Finally the result is summarized and presented in texts and charts. Results:The average age of Cu T users was 30.7 years and median was 30.0 at the time of Cu T insertion with standard deviation of ±7.1. Majority of Cu T insertions 95 (27.5%) were among women between 30 and 34 years of age. The duration of Cu T380A usage for 5 years before discontinuation was 202 (58.6%) and discontinuation before 5 years after insertion was 143 (41.4%). Among 345 subjects, majority of the women 37 (10.7%) discontinue within 2-3 years. Factors associated with discontinuation include bleeding 42 (29.37%) and automatic expulsion 32 (22.37%). The logistic regression analysis shows that women experiencing health problem after CU T380A insertion (bleeding), pain and automatic expulsion of IUCD have significantly associated with discontinuation of CU T 380A. Conclusion:Cu T 380A utilization rate for 5 years after insertion is so low (51.4%) in Adama town, which is almost equivalent with removal (41.6%). Therefore, our family planning providers has to be alert in addressing this obstacle so as to increase the discrepancy between continuation and removal rate.

description: We demonstrate a method of micromotion minimization of a trapped ion in a linear Paul trap based on the precision measurement of the ion trapping position displacement due to a stray electric field in the radial plane by ion fluorescence imaging. The amount of displacement in the radial plane is proportional to the strength of a stray electric field. Therefore, we evaluated the micromotion compensation condition by measuring the ion displacements from the ion equilibrium position using two different radial trap frequencies with various combinations of the compensation voltage. The residual electric field uncertainty of this technique reached a few volts per meter. This compensation technique does not depend on the orientation of the incident cooling laser or the detuning and imaging direction. Therefore, this method is suitable for a planar ion trap, a stylus ion trap, which limits the propagation angle of lasers, or miniaturized ion trap systems for sensing and metrological applications.

description: Family Latridae Gill   Diagnosis. Latridae can be diagnosed by the following combination of characters: body ovoid to elongate and compressed or round in cross-section; dorsal-fin elements XV–XXV, 22–44; anal-fin elements III, 7–37; pectoralfin rays 14 with ventral rays thick and unbranched. Gas bladder present; supraneurals never in the arrangement of Cheilodactylidae—all genera except Mendosoma with two supraneurals prior to first dorsal pterygiophore in arrangement of 0+0/2; no cirri on dorsal-fin elements. Latridae can be distinguished from all other cirrhitoids by having two supraneurals preceding the first neural spine, except for Mendosoma, which can be distinguished by having a single dorsal-fin spine articulating with the first dorsal pterygiophore (as opposed to two in all other families within Cirrhitoidei; Fig. 2). While not all larvae have been described, Latridae remains the only family in Cirrhitoidei to exhibit a late-larval ‘paperfish’ stage where larvae have deep bodies with a strong ventral keel adapted for pelagic life.

description: Research about practitioners’ application of the Communities of Inquiry pedagogy (‘CoI’) in professional disciplines is often unclear about: (a) how CoI contributed to the development or better understanding of practice; (b) how reflection on practice contributed to the development of the literature on how CoI is enacted in practice; and (c) the theory of professional learning adopted. This thesis reports on a three-cycle action research project in which I enacted CoI across several iterations of my undergraduate teaching practice in legal education. My analysis draws on Beach’s concept of learning as a consequential transition to examine how CoI can facilitate students’ struggle to establish themselves as lawyers. Within each research cycle I generated evidence concerning student perceptions of how I supported progress through the inquiry process and the forging of their emerging identity as lawyers. Data were generated from interviews, student survey responses and a teaching journal. Interim analysis of this material at the end of each cycle informed the design in later cycles. The core findings are that the teacher, research postgraduate students trained to act as facilitators and students need to collaborate to provide the teaching presence needed for the successful enactment of CoI. This collaboration, and the virtues it requires, are inadequately depicted in Garrison’s CoI model (Garrison, 2016). Furthermore, I argue that authentic assessments and appropriate ‘framing’ of student work as a contribution to knowledge play a key role in facilitating students’ consequential transitions. This research contributes to the CoI literature by highlighting the need for teachers to skillfully create a system of inter-locking levels of support for student inquiry as an important element of teaching presence. It contributes to the consequential transitions literature by emphasising the importance of a rich ecology of relevant social relations and of engaging students in authentic assessments and knowledge production.

The three-dimensional horizons are considered to have Bianchi types $II$ and $III$ symmetries, and hence the horizons are modeled on two types of Thurston $3$-geometries, namely the Nil geometry and $H^2\times R$. Being foliated by compact 3-manifolds, the horizons are neither spherical, hyperbolic, nor toroidal, and therefore are not of the previously studied topological black hole solutions in Hořava-Lifshitz gravity. Using the Hamiltonian formalism, we establish the conventional thermodynamics of the solutions defining the mass and entropy of the black hole solutions for several classes of solutions. It turned out that for both horizon geometries the area term in the entropy receives two non-logarithmic negative corrections proportional to Hořava-Lifshitz parameters. Also, we show that choosing some proper set of parameters the solutions can exhibit locally stable or unstable behavior.

description: We discuss the four dimensional effective action for type IIB flux compactifications, and obtain the quadratic terms taking warp effects into account. The analysis includes both the 4-d zero modes and their KK excitations, which become light at large warping. We identify an `axial' type gauge for the supergravity fluctuations, which makes the four dimensional degrees of freedom manifest. The other key ingredient is the existence of constraints coming from the ten dimensional equations of motion. Applying these conditions leads to considerable simplifications, enabling us to obtain the low energy lagrangian explicitly. In particular, the warped Kähler potential for metric moduli is computed and it is shown that there are no mixings with the KK fluctuations and the result differs from previous proposals. The four dimensional potential contains a generalization of the Gukov-Vafa-Witten term, plus usual mass terms for KK modes.

description: Τα Μαζικά Ανοικτά Διαδικτυακά Μαθήματα (Μassive Open Online Courses) αποτελούν μία αρκετά πρόσφατη εξέλιξη στο χώρο της εξ'αποστάσεως εκπαίδευσης. Τα τελευταία χρόνια τα ΜOOCs ξένων γλωσσών (Language Massive Open Online Courses) συμπεριλαμβάνονται πλέον στον κατάλογο των προσφερόμενων μαθημάτων από τους σημαντικότερους παροχείς ΜOOCs, όπως edX, Coursera, Udemy και FuterLearn. Για τους εκπαιδευόμενους τα LMOOCs προσφέρουν μία καινοτόμο και προσιτή εναλλακτική στην επίσημη και παραδοσιακή εκμάθηση των ξένων γλωσσών. Για τους εκπαιδευτικούς και τους υπεύθυνους σχεδιασμού μαθημάτων αυτό το ανερχόμενο διδακτικό μοντέλο για την διδασκαλία των ξένων γλωσσών εγείρει σοβαρά ζητήματα σχετικά με την αποτελεσματικότητα του νέου μαθησιακού περιβάλλοντος και την παροχή μίας παιδαγωγικής προσέγγισης που διευκολύνει περαιτέρω τις μαθησιακές εμπειρίες και τονώνει το στοχασμό για τις γλώσσες. Η παρούσα εργασία διερευνά την παρουσία των MOOCs στο διεθνές εκπαιδευτικό τοπίο και την εκπαιδευτική τους αξιοποίηση ως πηγή νέων προσεγγίσεων για τη διδασκαλία / εκμάθηση των ξένων γλωσσών
description: Massive Open Online Courses (Μassive Open Online Courses) are a fairly recent development in the area of distance education. In recent years, LMOOCs (Language Massive Open Online Courses) are included in the list of courses offered by major MOOCs providers such as edX, Coursera, Udemy and FuterLearn. For learners LMOOCs offer an innovative and affordable alternative to formal and traditional language learning. For teachers and course designers this emerging teaching model for language learning raises serious issues about the effectiveness of the new learning environment and the implementation of a pedagological approach that further facilitates learning and stimulates reflection on languages. The present study explores the presence of MOOCs in the international educational landscape and their educational use as a source of new approaches to the teaching / learning of foreign languages

description: Interacting dark energy models have been proposed as attractive alternatives to $Λ$CDM. Forthcoming Stage-IV galaxy clustering surveys will constrain these models, but they require accurate modelling of the galaxy power spectrum multipoles on mildly non-linear scales. In this work we consider a dark scattering model with a simple 1-parameter extension to $w$CDM - adding only $A$, which describes a pure momentum exchange between dark energy and dark matter. We then provide a comprehensive comparison of three approaches of modeling non-linearities, while including the effects of this dark sector coupling. We base our modeling of non-linearities on the two most popular perturbation theory approaches: TNS and EFTofLSS. To test the validity and precision of the modelling, we perform an MCMC analysis using simulated data corresponding to a $Λ$CDM fiducial cosmology and Stage-IV surveys specifications in two redshift bins, $z=0.5$ and $z=1$. We find the most complex EFTofLSS-based model studied to be better suited at both, describing the mock data up to smaller scales, and extracting the most information. Using this model, we forecast uncertainties on the dark energy equation of state, $w$, and on the interaction parameter, $A$, finding $σ_w=0.06$ and $σ_A=1.1$ b/GeV for the analysis at $z=0.5$ and $σ_w=0.06$ and $σ_A=2.0$ b/GeV for the analysis at $z=1$. In addition, we show that a false detection of exotic dark energy up to 3$σ$ would occur should the non-linear modelling be incorrect, demonstrating the importance of the validation stage for accurate interpretation of measurements.

description: Η «Αραβική Άνοιξη» είναι γνωστή με πολλά ονόματα όπως η «Επανάσταση του Γιασεμιού», η «Αραβική Επανάσταση» κτλ. Ο αντίκτυπός της στη ζωή του αραβικού λαού παραμένει άγνωστος μέχρι σήμερα, καθώς υπάρχουν πολλές διαφορετικές απόψεις. Επιπλέον, υπάρχουν πολλές έρευνες για την «Αραβική Άνοιξη» και τη ροή των πληροφοριών από εξέχουσες εταιρείες μέσων μαζικής ενημέρωσης. Ωστόσο, λίγες από αυτές λαμβάνουν υπόψη το κινεζικό τοπίο των μέσων ενημέρωσης και την αυξανόμενη επιρροή του. Ως αποτέλεσμα, αυτή η μεταπτυχιακή διατριβή προσπαθεί να αποκαλύψει την «πλαισίωση» των ακόλουθων ειδησεογραφικών οργανώσεων, Al Jazeera, BBC και China Daily. Η έρευνα επικεντρώνεται σε μια περίοδο πέντε ημερών (9-13 Φεβρουαρίου 2011) με δείγμα 92 άρθρων μέσω της χρήσης του Open Calais. Το κύριο συμπέρασμα είναι ότι όλοι οι εξετασμένοι οργανισμοί ειδήσεων απεικόνισαν τα γεγονότα με το την «πλαισίωση» της κοινωνικής αναταραχής. Έτσι, αυτή η μελέτη παρουσιάζει νέα ευρήματα για την έρευνα της Αραβικής Άνοιξης εξαιτίας του γεγονότος ότι όλοι οι προαναφερθέντες ειδησεογραφικοί οργανισμοί δεν έδιναν καμία προσοχή στα ατομικά χαρακτηριστικά των ανθρώπων που συμμετείχαν στις εξεγέρσεις και αντιμετώπιζαν τους διαδηλωτές ως ενοποιημένο πλήθος που προκαλεί κοινωνικές αναταραχές. Ως αποτέλεσμα, αυτή η «πλαισίωση» μπορεί να οδηγήσει στην υιοθέτηση αρνητικών ή θετικών χαρακτηριστικών για ολόκληρο το κίνημα, τα οποία εξαρτώνται από την αφήγηση κάθε ειδησεογραφικού οργανισμού.
description: ‘Arab Spring’ is known with several names such as ‘Jasmine Revolution’, and ‘Arab Evolution’. Its impact on the lives of the Arab people remains unknown until today, as there are many different opinions. Moreover, there exist many researches on the Arab Spring and the information flow conducted by prominent media companies. However, few of them take into consideration the Chinese media landscape and its growing influence. As a result, this MA dissertation tries to reveal the framing of the followed news organizations, Al Jazeera, BBC, and China Daily. The research focuses on a five-day period of time (9-13 February 2011) sample of 92 articles via the usage of Open Calais. The main finding is that all of the examined news organizations portrayed the events with the Civil unrest frame. Thus, this study displays new findings for the research of the Arab Spring because of the fact that all of the aforementioned news organizations paid no attention to the individual characteristics of the people that participated at the uprisings and treated the protesters as a unified crowd that causes civil unrest. As a result, this framing can lead to the adoption of negative or positive characteristics for the whole movement, which are relied on the narrative of each news organization.

description: Magnetic properties of A2BB'O6 (A = rare or alkaline earth ions; B,B' = transition metal ions) double perovskites are of great interest due to their potential spintronic applications. Particularly fascinating is the zero field cooled exchange bias (ZEB) effect observed for the hole doped La2-xAxCoMnO6 polycrystalline samples. In this work we synthesize La2CoMnO6, La1.5Ca0.5CoMnO6, and La1.5Sr0.5CoMnO6 single crystals by the floating zone method and study their magnetic behavior. The three materials are ferromagnetic. Surprisingly, we observe no zero or even conventional exchange bias effect for the Ca and Sr doped single crystals, in sharp contrast to polycrystalline samples. This absence indicates that the lack of grain boundaries and spin glass-like behavior, not observed in our samples, might be key ingredients for the spontaneous exchange bias phenomena seen in polycrystalline samples.

description: Η νανοτεχνολογία δίνει καινούριες προοπτικές στις βιοϊατρικές τεχνολογίες μέσω υλικών που στοχεύουν στην ταυτόχρονη θεραπεία και διάγνωση (theranostics). Τα μαγνητικά νανοσωματίδια έχουν προταθεί για τέτοιου είδους εφαρμογές ως μεταφορείς φαρμάκων. Η στοχευμένη θεραπεία έχει στόχο την αποτελεσματική μεταφορά αντιφλεγμονωδών φαρμάκων στον ανθρώπινο οργανισμό με αποτέλεσμα να μειώνονται οι δοσολογίες και οι παρενέργειες που προκαλούνται από αυτές. Η παρούσα εργασία αναφέρεται στη διαλυτοθερμική σύνθεση επικαλυμμένων φερριτών μαγγανίου ως μεταφορείς αντιφλεγμονωδών φαρμάκων. Συγκεκριμένα παράχθηκαν φερρίτες μαγγανίου με ελεύθερες αμινο-ομάδες οι οποίοι τροποποιήθηκαν περαιτέρω με τρία αντιφλεγμονώδη φάρμακα διαφορετικού μοριακού βάρους και λιποφιλικότητας και φερρίτες χωρίς ελεύθερες αμινο-ομάδες στους οποίους προσροφήθηκαν τα εν λόγω αντιφλεγμονώδη φάρμακα με τη βοήθεια πολυμερούς. Ακολούθησε ενδελεχής χαρακτηρισμός τους με φασματοσκοπία υπερύθρου (FT-IR), θερμοβαρυτική ανάλυση (ΤGA), φασματοσκοπία υπεριώδους-ορατού (Uv-vis) και περίθλαση ακτινών Χ (XRD). Στη συνέχεια έγινε η μελέτη της απελευθέρωσης των φαρμάκων σε ρυθμιστικά διαλύματα διαφορετικού pH.
description: Νanotechnology gives new perspectives in therapy with new materials that can be used for simultaneous therapy and diagnosis (theranostics). Magnetic nanoparticles have been proposed for these kinds of applications. In this thesis, coated nanoparticles with free amine as well as coated aminated nanoparticles were synthesized with the solvothermal method. These nanoparticles were characterized using infrared (Ft-IR) and ultra violet (Uv-vis) spectroscopy, thermogravimetric analysis (TGA) and x-ray diffraction (XRD) and then modified further with anti-inflammatory drugs. Lastly, their release profile was studied and compared.
