MORPHOLOGICAL, PHYSICAL AND THERMAL CHARACTERIZATION OF MICROFIBRILLATED CELLULOSE

ABSTRACT The aim of this study was to characterize microfibrillated cellulose (MFC) produced with a Masuko Sangyo Super Masscolloider using bleached and unbleached pulp of Eucalyptus spp. The MFC was characterized regarding morphology (TEM), crystallinity, viscosity, zeta potential and thermal properties (TGA). Regardless of the fiber type, the processing dramatically reduced the dimensions of the material, so as to obtain structures with nanometric dimensions. MFC produced with unbleached pulp preserved the original brown color of the pulp, which may be advantageous for some applications in the packaging sector, while films produced with bleached pulp were more translucent. The MFC showed lower values of viscosity and crystallinity index in relation to cellulosic pulp. The zeta potential was influenced by the type of fiber used. The main thermal transitions in MFC occurred after 200 ºC, demonstrating the potential of this material forhigh-temperature applications.
MOLI: multi-omics late integration with deep neural networks for drug response prediction

Motivation Historically, gene expression has been shown to be the most informative data for drug response prediction. Recent evidence suggests that integrating additional omics can improve the prediction accuracy which raises the question of how to integrate the additional omics. Regardless of the integration strategy, clinical utility and translatability are crucial. Thus, we reasoned a multi-omics approach combined with clinical datasets would improve drug response prediction and clinical relevance. Results We propose MOLI, a Multi-Omics Late Integration method based on deep neural networks. MOLI takes somatic mutation, copy number aberration, and gene expression data as input, and integrates them for drug response prediction. MOLI uses type-specific encoding subnetworks to learn features for each omics type, concatenates them into one representation and optimizes this representation via a combined cost function consisting of a triplet loss and a binary cross-entropy loss. The former makes the representations of responder samples more similar to each and different from the non-responders, and the latter makes this representation predictive of the response values. We validate MOLI on in vitro and in vivo datasets for five chemotherapy agents and two targeted therapeutics. Compared to state-of-the-art single-omics and early integration multi-omics methods, MOLI achieves higher prediction accuracy in external validations. Moreover, a significant improvement in MOLI’s performance is observed for targeted drugs when training on a pan-drug input, i.e. using all the drugs with the same target compared to training only on drug-specific inputs. MOLI’s high predictive power suggests it may have utility in precision oncology.

Intermediate band solar cells: Present and future

In the quest for high‐efficiency photovoltaics (PV), the intermediate band solar cell (IBSC) was proposed in 1997 as an alternative to tandem solar cells. The IBSC offers 63% efficiency under maximum solar concentration using a single semiconductor material. This high‐efficiency limit attracted the attention of the PV community, yielding to numerous intermediate band (IB) studies and IBSC prototypes employing a plethora of candidate IB materials. As a consequence, the principles of operation of the IBSC have been demonstrated, and the particularities and difficulties inherent to each different technological implementation of the IBSC have been reasonably identified and understood. From a theoretical and experimental point of view, the IBSC research has reached a mature stage. Yet we feel that, driven by the large number of explored materials and technologies so far, there is some confusion about what route the IBSC research should take to transition from the proof of concept to high efficiency. In this work, we give our view on which the next steps should be. For this, first, we briefly review the theoretical framework of the IBSC, the achieved experimental milestones, and the different technological approaches used, with special emphasis on those recently proposed.
Assessing Desert Dust Indirect Effects on Cloud Microphysics through a Cloud Nucleation Scheme: A Case Study over the Western Mediterranean

In this study, the performance and characteristics of the advanced cloud nucleation scheme of Fountoukis and Nenes, embedded in the fully coupled Weather Research and Forecasting/Chemistry (WRF/Chem) model, are investigated. Furthermore, the impact of dust particles on the distribution of the cloud condensation nuclei (CCN) and the way they modify the pattern of the precipitation are also examined. For the simulation of dust particle concentration, the Georgia Tech Goddard Global Ozone Chemistry Aerosol Radiation and Transport of Air Force Weather Agency (GOCART-AFWA) is used as it includes components for the representation of dust emission and transport. The aerosol activation parameterization scheme of Fountoukis and Nenes has been implemented in the six-class WRF double-moment (WDM6) microphysics scheme, which treats the CCN distribution as a prognostic variable, but does not take into account the concentration of dust aerosols. Additionally, the presence of dust particles that may facilitate the activation of CCN into cloud or rain droplets has also been incorporated in the cumulus scheme of Grell and Freitas. The embedded scheme is assessed through a case study of significant dust advection over the Western Mediterranean, characterized by severe rainfall. Inclusion of CCN based on prognostic dust particles leads to the suppression of precipitation over hazy areas. On the contrary, precipitation is enhanced over areas away from the dust event. The new prognostic CCN distribution improves in general the forecasting skill of the model as bias scores, the root mean square error (RMSE), false alarm ratio (FAR) and frequencies of missed forecasts (FOM) are limited when modelled data are compared against satellite, LIDAR and aircraft observations.
Plasma simulation for dual-frequency capacitively coupled plasma incorporating gas flow simulation

We aimed to improve the calculation accuracy by focusing on the neutral radical Ar* and electron density in a dual-frequency excited Ar plasma. The neutral radical Ar* has a long lifetime and becomes exhausted without actually disappearing. The coupled calculation of plasma and gas flow simulation was performed, and confirmed that Ar* in the coupled calculation spreads around, which was not shown by plasma simulation only. Regarding electron density, the effect of the secondary electron emission (SEE) factor was evaluated on basis of the measured electron density. The errors of electron densities between the experimental and simulation results were decreased from 36% to 17% by adding the effect of secondary electrons from the electrodes to the plasma simulation. It was shown that the coupled calculation and the addition of SEE are effective for calculating the dual-frequency excited Ar plasma.
The Role of Travel Motivations and Social Media Use in Consumer Interactive Behaviour: A Uses and Gratifications Perspective

This paper explores the influence of travel motivations and the gratification provided by social media in consumer stickiness to social media, intention to create user-generated content, and electronic word of mouth (eWOM) review adoption. The study follows a mixed-methods approach. First, a concept mapping study was undertaken to identify the main travel motivations and the gratifications provided by social media when consumers search for information on tourism destinations. A second study using structural equation modelling and SmartPLS 3.2. 7 with a sample of 401 heavy users of social media showed the relationships between individual travel motivations and gratifications provided by social media and consumer stickiness, intention to share user-generated content (UGC), and eWOM review adoption.
Reproductive cycle of the European clam Ruditapes decussatus from Óbidos Lagoon, Leiria, Portugal

ABSTRACT In Portugal, the European clam (Ruditapes decussatus) is an important commercial resource. Óbidos Lagoon is a strong candidate as a cultivation area to increase European clam exploitation. However, the reproductive biology of this population has not been described. In this work, the reproductive cycle of R. decussatus was characterized by determining gonadal development stages, gonad index, condition index, and biochemical composition. The relationship between reproduction and environmental parameters (sea surface temperature, chlorophyll a, and particulate organic matter) was assessed. Ruditapes decussatus had an annual reproductive cycle. The gametogenic cycle started in late winter, and the ripe stage in spring was followed by spawning that began at the end of spring/early summer and extended until early autumn. The subsequent period of sexual rest occurred during the winter. Condition index showed seasonal variations related to food availability (chlorophyll a). The European clams in Óbidos Lagoon recovered rapidly after their reproductive period, most likely owing to the availability of food. This study will help to improve sustainable management of this wild stock and is important for future aquaculture development of this species.
Type 2 diabetes mellitus patients’ satisfaction with pharmacy services in Wollega University Referral Hospital, Western Ethiopia

Introduction: Ensuring the quality of pharmaceutical services in hospitals is an integral aspect of providing quality of health care. In this regard, it has long been proven that the adoption of the concept of pharmaceutical care is essential to improve the quality of pharmaceutical services. Hence, this study aimed to assess type 2 diabetes mellitus patients’ satisfaction with pharmacy services in Wollega University Referral Hospital, West Ethiopia. Methods: Descriptive cross-sectional study design was employed from May to June 2019. Data were collected using both close and open-ended questionnaires from the sample of type 2 diabetes mellitus patients. The collected data were analyzed using Statistical Package for Social Science version 20 and Descriptive data were explained by frequency and percentage. Results: From a total of 195 study participants, 124 (64%) were satisfied with pharmacy service. Patients who were satisfied with pharmacy services reported possible reasons like availability of the prescribed drugs, affordability, and notice of information on the drug package that is not taken with foods. However, patients were dissatisfied with other pharmacy related factors like the reflection of negative attitude from the pharmacists and withholding information on what to do during the occurrences of adverse effects. About two thirds (67.8%) patients agreed with the availability of prescribed medicines. None of the patients had negative attitude toward the pharmacists. About 43.1% of the patients strongly disagreed with unclear instruction of taking medicines. Conclusion: The patients’ satisfaction level with pharmacy service was affected by different pharmacy service-related factors. The management of Wollega University Referral Hospital has to establish and activate information centers to sufficiently provide drug information for the patients and motivate pharmacists morally and financially.

Various coating designs were prepared using either reactive or ionassisted e-beam deposition technology and tested at 1030 nm 10 ns in r-on-1 mode according to the ISO 21254 standard. Measured damage thresholds were compared and LIDT was discussed with respect to thin-film design and coating technology.
Controls on Reservoir Heterogeneity of a Shallow-Marine Reservoir in Sawan Gas Field, SE Pakistan: Implications for Reservoir Quality Prediction Using Acoustic Impedance Inversion

The precise characterization of reservoir parameters is vital for future development and prospect evaluation of oil and gas fields. C-sand and B-sand intervals of the Lower Goru Formation (LGF) within the Lower Indus Basin (LIB) are proven reservoirs. Conventional seismic amplitude interpretation fails to delineate the heterogeneity of the sand-shale facies distribution due to limited seismic resolution in the Sawan gas field (SGF). The high heterogeneity and low resolution make it challenging to characterize the reservoir thickness, reservoir porosity, and the factors controlling the heterogeneity. Constrained sparse spike inversion (CSSI) is employed using 3D seismic and well log data to characterize and discriminate the lithofacies, impedance, porosity, and thickness (sand-ratio) of the C- and B-sand intervals of the LGF. The achieved results disclose that the CSSI delineated the extent of lithofacies, heterogeneity, and precise characterization of reservoir parameters within the zone of interest (ZOI). The sand facies of C- and B-sand intervals are characterized by low acoustic impedance (AI) values (8 × 106 kg/m2s to 1 × 107 kg/m2s), maximum sand-ratio (0.6 to 0.9), and maximum porosity (10% to 24%). The primary reservoir (C-sand) has an excellent ability to produce the maximum yield of gas due to low AI (8 × 106 kg/m2s), maximum reservoir thickness (0.9), and porosity (24%). However, the secondary reservoir (B-sand) also has a good capacity for gas production due to low AI (1 × 107 kg/m2s), decent sand-ratio (0.6), and average porosity (14%), if properly evaluated. The time-slices of porosity and sand-ratio maps have revealed the location of low-impedance, maximum porosity, and maximum sand-ratio that can be exploited for future drillings. Rock physics analysis using AI through inverse and direct relationships successfully discriminated against the heterogeneity between the sand facies and shale facies. In the corollary, we proposed that pre-conditioning through comprehensive petrophysical, inversion, and rock physics analysis are imperative tools to calibrate the factors controlling the reservoir heterogeneity and for better reservoir quality measurement in the fluvial shallow-marine deltaic basins.
Variability of trans and cis resveratrol and their glucosides in red wines produced in Sardinia and Corsica.

Variability of trans - and cis -resveratrol and their glucosides in red wines produced in Sardinia and Corsica was determined by HPLC. The data obtained were elaborated by multivariate statistical analysis (Principal Component Analysis). The results showed a higher average total stilbene content in Corsican samples than in Sardinian samples, due to the aglycons content. Furthermore, PCA pointed out a good separation between the two groups which seems to be related to the samples origin. Lastly, the Cagnulari, which is a particular Sardinian cultivar, showed high values of total stilbenes, related to the glucoside content, as did three Corsican samples.

Topical antibiotic therapy in eye infections - myths and certainties in the era of bacterial resistance to antibiotics

Globally, the alarming increase in the rate of antibiotic (AB) resistance of bacteria is currently considered one of the 7 major threats to the human race along with terrorism, nuclear proliferation and pollution. Judicious use of AB by physicians in all medical and surgical specialties is essential to limit the extent of resistance to AB. In Europe, Romania ranks among the first in terms of the rate of resistance to AB of the main bacteria involved in eye infections (EI). The principles of a judicious antibiotic therapy in ophthalmology are: performing the bacteriological determinations necessary to establish the bacterium involved in EI and its sensitivity to AB; avoiding the treatment of viral infections with AB; knowledge of the local rate of resistance of bacteria to AB; first choice of an AB with a spectrum appropriate to the aetiology of EI; the chosen AB must penetrate well into the eye tissues; using the local route of administration whenever possible; avoiding sub-dosing and shortening the duration of antibiotic therapy; abandoning the “myth” that a “in vitro” bactericidal AB would be inherently more clinically effective (“in vivo”) than a bacteriostatic AB; requesting the consultation of infectious diseases for EI with AB multidrug-resistant bacteria. The available ophthalmic topics contain antibiotics from the following classes: aminoglycosides, fluoroquinolones, chloramphenicol, glycopeptides, polymyxins, etc. The increase in the fluoroquinolone resistance rate of the bacteria involved in EI has recently led to the recommendation that, in the absence of the antibiogram, it is best to avoid first-line antibiotic therapy with topical fluoroquinolones alone in keratitis.
