Food waste valorization options: opportunities from the bioeconomy
Authors: Imbert Enrica
Published: April 2017

The world is confronted with the depletion of natural resources due to their unsustainable use, increased global competiveness, increasing population and other environmental and economic challenges. Under the European 2020 growth strategy launched in 2010, Europe has set itself the goal of shifting from linear to circular models of production and consumption. In this context, food waste management poses a great challenge. This study focusses on the possible destinations for food waste, specifically, on the most sustainable practices that turn waste into valuable resources. Particular attention is devoted to the potential offered by fast-growing sectors such as the bioeconomy, which is contributing to increased energy and materials production with reduced environmental impact, at the same time creating new job opportunities. In this paper we will argue that an holistic approach considering the issue of food wastage as part of a broader emerging bio-economy and circular-economic model, might provide win-win solutions able to minimize wastage, promote income growth and job creation, and prompt sustainable local development. However, in order to enable an effective transition to a circular bioeconomy able to minimize the impact of food wastage, the economic, social, and environmental sustainability of this new model must be properly evaluated through appropriate tools, e.g. through an overall Life Cycle Sustainability Assessment (LCSA).

Published: April 2017

The poly(vinylidene fluoride) (PVDF)/chitin (CH) blend membranes were prepared by the immersion phase inversion method using N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl) as the co-solvent. It was found that blending CH with PVDF allowed membranes to have a better hydrophilicity, penetrability, antifouling and antibacterial performance. In order to improve the performance of PVDF/CH blend membranes further, water/ethanoic acid (HAc) solutions with different compositions were employed as coagulation baths. The effects of HAc volume percentage in coagulation baths on the surface composition, morphology, wettability, water flux, antifouling and antibacterial property of PVDF/CH membrane were investigated. The results indicated that the content of CH on the surface of the membrane increased with the increase of HAc concentration in coagulation baths, which contributed to an improvement of hydrophilicity. The increasing HAc content in coagulation baths also led to a change from finger-like pores to sponge-like pores and a decrease of porosity for PVDF/CH blend membranes. When increasing HAc concentration, the antifouling performance of the blend membranes was improved. Meanwhile, the amidogen of CH on PVDF/CH membrane surfaces could suppress the growth of bacteria, and the blend membrane showed an improved antibacterial performance with the volume ratio of HAc increasing.
Modelling drug transport during intraperitoneal chemotherapy
Authors: Steuperaert Margo , Debbaut Charlotte , Segers Patrick , Ceelen Wim
Published: April 2017

Despite a strong rationale for intraperitoneal (IP) chemotherapy, the actual use of the procedure is limited by the poor penetration depth of the drug into the tissue. Drug penetration into solid tumours is a complex mass transport process that involves multiple parameters not only related to the used cytotoxic agent but also to the tumour tissue properties and even the therapeutic setup. Mathematical modelling can provide unique insights into the different transport barriers that occur during IP chemotherapy as well as offer the possibility to test different protocols or drugs without the need for in vivo experiments. In this work, a distinction is made between three different types of model: the lumped parameter model, the distributed model and the cell-based model. For each model, we discuss which steps of the transport process are included and where assumptions are made. Finally, we focus on the advantages and main limitations of each category and discuss some future perspectives for the modelling of IP chemotherapy.

Published: April 2017

There are many factors that strongly influence the aetiology, development, and progression of cognitive decline in old age, mild cognitive impairment (MCI), and Alzheimer’s disease (AD). These factors include not only different personality traits and moods but also lifestyle patterns (e.g. exercise and diet) and awareness levels that lead to cognitive decline in old age. In this review, we discuss how personality traits, mood states, and lifestyle impact brain and behaviour in older adults. Specifically, our review shows that these lifestyle and personality factors affect several brain regions, including the hippocampus, a region key for memory that is affected by cognitive decline in old age as well as AD. Accordingly, appropriate recommendations are presented in this review to assist individuals in decreasing chances of MCI, dementia, AD, and associated symptoms.
Co-Investments and Tacit Collusion in Regulated Network Industries: Experimental Evidence
Authors: Krämer Jan , Vogelsang Ingo
Published: April 2017

Several regulatory authorities have recently allowed competing network operators to co-invest in network infrastructure. With the use of a laboratory experiment, we investigate the impact of co-investments on competition in regulated network industries, particularly in comparison to unilateral and duplicate investments. Our main finding is that co-investment (i.e. cooperation at the infrastructure level) facilitates tacit collusion (i.e. cooperation at the retail level) significantly, which questions the positive evaluation of co-investments with respect to consumers’ surplus in the theoretical literature.
The influence of modern media on the development of fan groups and the promotion of hooliganism
Authors: Nikolić Miljana
Published: April 2017

Since the first sport duels, and with the development of sport through the ages, there were sport fans that cheered either for one or the other opponent and in that way they showed their sympathy. As the time passed, they organized themselves in fan groups, and they became not only an agent of socialization, but also a very important factor in directing social happenings. Hooliganism was created in modern society, and it had devastating effects on both sport and socially-political relations. The functioning of the fan groups that embraces hooliganism, demands high level of organization, so the modern media became a major tool of communication. The aim of this work is to determine in which way, not only the modern media but more importantly the internet sites and the social media of the fan groups, have been used for not only promoting and giving information about their actions, goals and attitude but also promotion of hooliganism.
Claiming Spaces for Science
Authors: Sowards Adam M.
Published: April 2017

Exploration has always centered on claims: for country, for commerce, for character. Claims for useful scientific knowledge also grew out of exploration’s varied activities across space and time. The history of the Canadian Arctic Expedition of 1913–18 exposes the complicated process of claim-making. The expedition operated in and made claims on many spaces, both material and rhetorical, or, put differently, in several natural and discursive spaces. In making claims for science, the explorer-scientists navigated competing demands on their commitments and activities from their own predilections and from external forces. Incorporating Arctic spaces into the Canadian polity had become a high priority during the era when the CAE traversed the Arctic. Science through exploration—practices on the ground and especially through scientific and popular discourse—facilitated this integration. So, claiming space was something done on the ground, through professional literature, and within popular narratives—and not always for the same ends. The resulting narrative tensions reveal the messy material, political, and rhetorical spaces where humans do science. This article demonstrates how explorer-scientists claimed material and discursive spaces to establish and solidify their scientific authority. When the CAE claimed its spaces in nature, nation, and narrative, it refracted a reciprocal process whereby the demands of environment, state, and discourse also claimed the CAE.

Published: April 2017

The impact of thermal imprinting on the plasticity of the hypothalamic–pituitary–interrenal (HPI) axis and stress response in an adult ectotherm, the gilthead sea bream (Sparusaurata, L.), during its development was assessed. Fish were reared under 4 thermal regimes, and the resulting adults exposed to acute confinement stress and plasma cortisol levels and genes of the HPI axis were monitored. Changes in immune function, a common result of stress, were also evaluated using histomorphometric measurements of melanomacrophages centers (MMCs) in the head kidney and by monitoring macrophage-related transcripts. Thermal history significantly modified the HPI responsiveness in adult sea bream when eggs and larvae were reared at a higher than optimal temperature (HT, 22°C), and they had a reduced amplitude in their cortisol response and significantly upregulated pituitarypomcand head kidneystartranscripts. Additionally, after an acute stress challenge, immune function was modified and the head kidney of adult fish reared during development at high temperatures (HT and LHT, 18–22°C) had a decreased number of MMCs and a significant downregulation of dopachrome tautomerase. Thermal imprinting during development influenced adult sea bream physiology and increased plasma levels of glucose and sodium even in the absence of an acute stress in fish reared under a high–low thermal regime (HLT, 22–18°C). Overall, the results demonstrate that temperature during early development influences the adult HPI axis and immune function in a teleost fish.
Activation of the P2Y2 receptor regulates bone cell function by enhancing ATP release

Published: April 2017

Bone cells constitutively release ATP into the extracellular environment where it acts locally via P2 receptors to regulate bone cell function. Whilst P2Y2 receptor stimulation regulates bone mineralisation, the functional effects of this receptor in osteoclasts remain unknown. This investigation used the P2Y2 receptor knockout (P2Y2R−/−) mouse model to investigate the role of this receptor in bone. MicroCT analysis of P2Y2R−/− mice demonstrated age-related increases in trabecular bone volume (≤48%), number (≤30%) and thickness (≤17%). In vitro P2Y2R−/− osteoblasts displayed a 3-fold increase in bone formation and alkaline phosphatase activity, whilst P2Y2R−/− osteoclasts exhibited a 65% reduction in resorptive activity. Serum cross-linked C-telopeptide levels (CTX, resorption marker) were also decreased (≤35%). The resorption defect in P2Y2R−/− osteoclasts was rescued by the addition of exogenous ATP, suggesting that an ATP deficit could be a key factor in the reduced function of these cells. In agreement, we found that basal ATP release was reduced up to 53% in P2Y2R−/− osteoclasts. The P2Y2 receptor agonists, UTP and 2-thioUTP, increased osteoclast activity and ATP release in wild-type but not in P2Y2R−/− cells. This indicates that the P2Y2 receptor may regulate osteoclast function indirectly by promoting ATP release. UTP and 2-thioUTP also stimulate ATP release from osteoblasts suggesting that the P2Y2 receptor exerts a similar function in these cells. Taken together, our findings are consistent with the notion that the primary action of P2Y2 receptor signalling in bone is to regulate extracellular ATP levels.
Gestionar la transmisión del patrimonio: las familias y sus estrategias de reproducción social en la Francia rural, (siglos XVI-XIX)
Authors: Beaur Gérard
Published: April 2017

La cuestión de la herencia y su papel en el proceso de reproducción social y en la redefinición de las estructuras agrarias ha dado lugar a numerosos debates y trabajos en Francia. Si en un principio dicha cuestión se abordó gracias al estudio de las normas jurídicas, ahora se hace en cambio a partir de la realidad de las prácticas sucesorias, las cuales son examinadas y discutidas por los historiadores. Este trabajo trata de arrojar luz no solo sobre la diversidad de las formas de transmisión hereditaria que hubo en la Francia rural, sino también sobre las lógicas y las estrategias que subyacían tras las elecciones sucesorias que realizaban las familias. Conforme a ello, cuestiona los tópicos que los estudiosos de primera hora crearon sobre las familias que emplearon la partición igualitaria. Se acerca también a las reacciones de las distintas sociedades rurales frente a la ruptura con el pasado que supuso el desarrollo de la Revolución Francesa, y a las resistencias y estrategias hereditarias que éstas desarrollaron frente a la introducción del Código Civil. Constata así la enorme continuidad y plasticidad de las prácticas sucesorias en el tiempo; una plasticidad que demuestra que las familias fueron capaces de adaptar sus lógicas sucesorias a las cambiantes realidades socioeconómicas.
Immediate Reactions To Monoclonal Antibodies In Clinical Hematology
Authors: Kyriazi Vasiliki
Published: April 2017

Monoclonal antibodies (MoAbs) have been widely used in clinical hematology. As foreign macro-molecules, they can cause infusional reactions during the administration or within 24 hours after the infusion, which encompass a spectrum of mechanisms. Although most of these reactions are non-allergic, are often indistinguishable from true allergic reactions mediated by IgE immunoglobulins. The diagnosis is often challenging and relies mainly on clinical criteria. They occur during the first doses, soon after the initiation of treatment. The symptoms are usually well controlled by the immediate drug discontinuation or reduction of the infusion rate. The management remains largely supportive, consisting of oxygen, intravenous fluids, bronchodilators, antihistamines and steroids. Most of MoAb protocols recommend premedication with steroids and antihistamines and gradually escalating infusion rates. Increased medical and nursing vigilance is required and resuscitative equipment should always be readily available. These events affect patients' quality of life, leading to treatment delay or discontinuation and series of tests. The decision to rechallenge the treatment depends on severity grading, clinical parameters and treatment goals. This article provides an update of MoAbs used in clinical hematology. It summarizes the pathophysiology, the diagnostic approach, the preventive measures and treatment of MoAb-related reactions.
Multiple myeloma revealed by a sphenoid plasmocytoma: case report and literature review
Authors: Kadiri Selma
Published: April 2017

Plasma cell neoplasms can manifest as a solitary or multiple plasmocytomas and may be associated with or progressing to multiple myeloma (MM). Cranial and intracranial plasmocytomas revealing multiple myeloma are very rare and only few cases are reported in the literature.

We report the case of a sphenoid plasmocytoma that revealed a multiple myeloma in a 56 year-old woman with 3 months history of temporal headache and diplopia. Magnetic resonance imaging (MRI) and computed tomography (CT) showed a sphenoid mass. An endoscopic sphenoidal biopsy was performed and the histopathological exams showed a plasmocytoma with a positive staining for CD138. Further biological studies confirmed the diagnosis of multiple myeloma with a monoclonal gamma peak of immunoglobulin (Ig) A. The patient started systemic chemotherapy and received decompressive radiation therapy on the sphenoidal sinus. She remained in remission for 8 months and died from renal dysfunction.

Although the sphenoid plasmocytoma is a very rare presentation of multiple myeloma it should be considered for effective patient management and prognosis improvement

Published: April 2017

Background: A number of questionnaire-based systems and the use of portable quantitative ultrasound scanners (QUS) have been devised in an attempt to produce a cost-effective method of screening for osteoporosis.
Objective: to assess the sensitivity and specificity of different techniques and their ability to act as screening tools in relation to dual energy X-ray absorptiometry (DXA).
Methods: 295 white postmenopausal women aged over 60 were enrolled. Each subject completed a standardized questionnaire which permits the measure of six osteoporosis indexes and had bone mineral density (BMD) measured using QUS and DXA. Sensitivity and specificity of the different techniques in relation to DXA were plotted as receiver-operating characteristic (ROC) curves at DXA T-score total hip ≤ -2.5 (osteoporosis).
Results: BUA sensitivity and specificity values were respectively 76.8% and 51.2% at the total hip. The optimal cut-off T-score for QUS was -2 at the total hip. The osteoporosis self-assessment tool (OST) provided consistently the highest AUC (0.80) among the clinical tools and had the best sensitivity and specificity balance (90.2%-44.5%). OST negative likelihood ratio was 0.22.
Conclusion: OST (based only on the weight and the age) performed slightly better than QUS and other risk questionnaires in predicting low BMD at the total hip

Neuroblastoma: Incidental Craniocerebral Metastasis - A Case Report
Authors: Jain Priyanka , Singlab Sahil
Published: April 2017

Neuroblastoma has been attributed the term “the great imitator” due to its varied spectrum of presentations. Although neuroblastoma is a common childhood malignancy, which frequently metastasizes, involvement of the Central nervous system is rarely reported in the literature. It commonly metastasizes to the base of the skull and orbits late in the disease. Early detection and aggressive treatment of this complication may allow some patients to live longer than they would have otherwise.

Published: April 2017

Introduction: Breast cancer remains despite the therapeutic progress, the leading cause of death by cancer among women. It represents a group of very heterogeneous clinical, histopathological and molecular diseases. Molecular heterogeneity has been demonstrated by genomic analysis, even for similar histology cancers. Four subgroups of breast carcinomas are distinguished: Luminal A, Luminal B, HER2 over expression and Basal - like. The Immuno-histo-chemical analysis useip (estrogen receptors) RE, the PR (progesterone receptors), the ((Human Epidermal Growth Factor Receptor-2), the Ki67 (proliferation marker) HER2, CK5/6) has shown a subdivision into subgroups similar to those found by genomic analysis. These subgroups are different from the point of view of clinical course and response to adjuvant treatment.

Objectives: The aim of this work is to study the molecular profile of the breast cancers by immunostaining on Moroccan series to a classification with a prognostic value allowing a treatment tailored to each group of patients. Furthermore, the molecular subgroups were correlated to other clinical and histological factors.

Material and methods: It is a prospective study of the laboratory of Anatomy and Pathologic cytology of the children's Hospital, the service I of the maternity hospital in Rabat and in cooperation with the United Nations Centre of pathological anatomy. To do this, 88 cases of breast cancer together were diagnosed between January 1, 2010 and December 31, 2014, taking a period of five years. All tissue samples made subject study of Immuno-histo-chemistry with the following markers: RE, PR, HER2 and Ki67. Only negative triple cases (HR and HER2 negative) benefited from an additional marking with CK5/6 and EGFR to set the basal profile.

Results: Series of 88 cases of mammary carcinomas observed on operating parts, ranged in age between 28 and 84 years old, with an average of 51 ± 12, 8. Carcinoma infiltrating non-specific (DOCTORS) was the most frequent (87.5%). Ranks histo-prognostic Scarff Bloom and Richardson (SBR) 2 and 3 respectively accounted for 45.5 and 51.1% of cases and only 2, 3% of the DOCTORS were grade 1. The Luminal B (53.4%) was under the most common molecular group, followed by Luminal A (23.9%), HER2 + (15.9%) and triple negative (6.8%). The correlation of molecular type of tumors with different prognostic factors showed only one significant connection with the SBR grade.
Exploring the effects of non-monetary reimbursement for participants in HCI research
Authors: Wiseman Sarah , Cox Anna L. , Gould Sandy J. J. , Brumby Duncan P.
Published: April 2017

When running experiments within the field of Human Computer Interaction (HCI) it is common practice to ask participants to come to a specified lab location, and reimburse them monetarily for their time and travel costs. This, however, is not the only means by which to encourage participation in scientific study. Citizen science projects, which encourage the public to become involved in scientific research, have had great success in getting people to act as sensors to collect data or to volunteer their idling computer or brain power to classify large data sets across a broad range of fields including biology, cosmology and physical and environmental science. This is often done without the expectation of payment. Additionally, data collection need not be done on behalf of an external researcher; the Quantified Self (QS) movement allows people to reflect on data they have collected about themselves. This too, then, is a form of non-reimbursed data collection. Here we investigate whether citizen HCI scientists and those interested in personal data produce reliable results compared to participants in more traditional lab-based studies. Through six studies, we explore how participation rates and data quality are affected by recruiting participants without monetary reimbursement: either by providing participants with data about themselves as reward (a QS approach), or by simply requesting help with no extrinsic reward (as in citizen science projects). We show that people are indeed willing to take part in online HCI research in the absence of extrinsic monetary reward, and that the data generated by participants who take part for selfless reasons, rather than for monetary reward, can be as high quality as data gathered in the lab and in addition may be of higher quality than data generated by participants given monetary reimbursement online. This suggests that large HCI experiments could be run online in the future, without having to incur the equally large reimbursement costs alongside the possibility of running experiments in environments outside of the lab.
Solvency effects of taxation: A comparison of Hungarian banks and insurance companies
Authors: Szüle Borbála
Published: April 2017

Recently, there has been a growing interest in the solvency of financial intermediaries. Bank and insurer insolvency cases generated numerous adverse economic effects and also promoted academic efforts to design solvency-related taxation methods. The focus of this paper is on corporate taxation and its empirical relation to solvency in the Hungarian financial intermediation sector. Based on the previous literature, a complex empirical model of the interactions between capital formation, asset growth and solvency risk is presented, and panel data results are compared for banks and insurance companies. A comparison with international empirical results is also possible, although it may only be of limited relevance due to some differences in solvency measurement. The paper also aims to highlight the potential differences between banking and insurance. As far as solvency effects are concerned, the empirical results do not reveal significant differences in these two sectors; however, other results point to the heterogeneity of the Hungarian financial intermediation sector.

Recent flaws in Evidence Based Medicine: statin effects in primary prevention and consequences of suspending the treatment.
Authors: Rabaeus Mikael , Nguyen Paul V , Lorgeril Michel de
Published: April 2017

Statin therapy is presented as a protection against ischemic heart disease (IHD) complications. As IHD is often a fatal disease, statins are thereby supposed to decrease cardiovascular mortality and increase life expectancy. However, these benefits are increasingly challenged in the medical community, the controversy being particularly intense when discussing the effects of statins in primary prevention and the consequences of statin discontinuation. Both primary prevention and treatment discontinuation have been recently used by investigators linked to the pharmaceutical industry to justify and boost prescription and consumption of statins and other cholesterol-lowering medications. We herein review some recent commercial data related to primary prevention with rosuvastatin and statin discontinuation and their respective effects on IHD and overall mortality rate. We conclude that (1) despite the recent hype raised by HOPE-3, the cholesterol-lowering rosuvastatin is likely not beneficial in intermediate-risk individuals without cardiovascular disease (primary prevention). This trial may even represent a typical example of how evidence-based medicine has been flawed in commercial studies. (2) Statin discontinuation does not lead to increased IHD and overall mortality, at least in the months following interruption of treatment. On the contrary, one might even conclude that statin discontinuation could save lives. One possible explanation of this apparently paradoxical finding is that statin discontinuers, in the same time they stop statin therapy, likely try to adopt a healthy lifestyle. Further studies are needed to confirm the real effects of statin discontinuation in various clinical conditions. In the meantime, it is not evidence based to claim that statin discontinuation increases mortality or saves lives.

RESUMO Entre as infecções fúngicas que afetam a pós-colheita da videira se destacam a podridão seca ocasionada por Lasiodiplodia theobromae que provoca perdas superiores as perdas no campo, pelo fato de serem adicionados aos custos de colheita, transporte e armazenamento. Produtos naturais vêm sendo utilizados no controle de doenças de plantas, apresentando eficiência na redução do uso de defensivos agrícolas. Desta forma, o presente trabalho teve por objetivo obter o controle da podridão seca pela utilização de produtos alternativos. Foi analisado o crescimento micelial de L. theobromae em placas de Petri contendo o meio BDA suplementado com os seguintes produtos: óleo de citronela, cravo e menta, nas concentrações de 1,0% e 1,5% e quitosana (1,5%). A testemunha foi placa com meio BDA sem adição de produto. Para avaliação do efeito curativo dos óleos sobre o desenvolvimento da podridão seca, cachos da cv Itália foram inoculados com o patógeno e, após 4 h, aspergidos com concentrações 1,0% e 1,5% de solução de óleos de cravo, citronela e menta e de Quitosana a 1,5% e água (testemunha). Posteriormente, para avaliar o efeito protetor dos cachos da cv Itália foram submetidos aos mesmos tratamentos e, inoculados após 4 horas com L. theobromae. Na avaliação do tempo de inoculação, cachos da cv. Itália foram aspergidos com solução de óleos essenciais: cravo (1,5%) e citronela (1,0% e 1,5%), e água (testemunha) e, inoculados após 24, 48, 72 ou 96 h com o fungo L. theobromae. Os óleos de Citronela e Menta, em todas as concentrações foram capazes de inibir o crescimento micelial de L. theobromae. Os óleos essenciais e Quitosana foram eficientes em reduzirem a incidência da podridão seca em cachos da videira cv Itália. No entanto, em relação à severidade apenas os óleos de citronela e menta, na concentração de 1,5% mantiveram a capacidade de reduzir a doença em 30 e 29,2%, respectivamente. O tempo de inoculação influenciou a incidência e a severidade da doença. Quanto mais tempo o material esperou para ser inoculado, maior foi à incidência e a severidade da doença.

Published: April 2017

ABSTRACT Objective: to investigate the perception of professionals from the health area regarding training for their teaching practice. Method: it is an exploratory, descriptive, prospective study, with qualitative analysis. The sample was made up of 85 lecturers from 10 undergraduate courses in the area of health, from a private Higher Education Institution in the Brazilian State of Rio Grande do Sul. Data collection was undertaken in 2014, through a questionnaire using the Qualtrics tool. Content analysis was used for analyzing the data. Results: the study made it possible to identify how the participants perceive the health professional: in general, as a health specialist able to work in different areas, but who lacks pedagogical training to undertake teaching. It was observed, furthermore, that these professionals seek development in the pedagogical aspects through formal, informal and non-formal education. Conclusion: the teaching practice of health professionals requires skills that go beyond the simple knowledge of contents

Published: April 2017

ABSTRACT The aim of this study was to identify the prevalence of satisfaction among accounting professors in Brazil throughout their careers. The research is classified as descriptive and used a quantitative approach to data analysis. 641 valid responses were obtained from professors from all regions of Brazil. The results show that a feeling of satisfaction prevails among accounting course professors, as most of them “like the profession” and, in general, "are satisfied with it”. It was found that levels of satisfaction are higher among individuals with more experience, in that in their first years in the job (one to three years), professors have lower satisfaction rates; the highest levels of satisfaction are found in the final stage (over 35 years). The main factor that influences satisfaction is personal fulfillment (teaching work and relationship with students). It was also possible to identify that positive feelings about teaching predominate (67.3%) compared to negative ones (32.7%). These results show the need for greater attention to be paid in the early years of the career in order to avoid a "reality clash". They also show the need for other studies to investigate how the phases in the life cycle of accounting professors are characterized.
The petrogenesis of tholeiitic diabases in eastern Parnaíba Basin: evidence for geochemical heterogeneities in the subcontinental lithospheric mantle in NE Brazil

Published: April 2017

ABSTRACT: The sedimentary rocks within the Paleozoic Parnaiba basin in NE Brazil were intruded by voluminous tholeiitic diabase sills and covered by coeval basaltic flows. This paper presents lithogeochemical data of borehole samples obtained from wells located in the eastern portion of the Parnaiba basin. The diabases are subalkaline tholeiitc rocks comprising three high-TiO2 and three low-TiO2 suites that are unrelated by differentiation processes. Fractional crystallization of olivine and augite was the predominantly evolutionary processes within individual high- and low-TiO2 suites as depicted by trace element geochemical modelling, exception being made for one low-TiO2 suite that evolved by AFC. Parental compositions for both low- and high-TiO2 suites are related with variably enriched, spinel harzburgitic sources likely to represent the heterogeneous subcontinental lithospheric mantle underneath the sedimentary basin. The geochemical provinciality of the Parnaiba tholeiitic magmatism seems unrelated with the Transbrasiliano Lineament but may be due to lithospheric mantle amalgamation and remobilization occurred during previous tectonic events.

ABSTRACT: This work presents the investigation in an environment that contains uranium deposits by using Pb isotope signatures. The study area, southeast of Brazil, is characterized by the lack of surface water and, as a consequence, the groundwater plays an important role in the economy of the region, such as the supply to the uranium industry and, above all serving the needs of the local population. The objective of the present investigation is the determination of the signatures of Pb in groundwater and sediments as well as the identification of environments under influences of geogenic and/or anthropogenic sources. It was determined that the Pb in the majority of sediments was geogenic in origin. Although data from the literature, related to the environmental studies, consider 206Pb/207Pb isotopic ratio values below or close to 1.2 as an indicative of anthropogenic Pb, the 206Pb/ 207Pb determined for the majority of groundwater samples ranged from 1.14 to 1.19, and are similar to the data reported for rocks samples (1.09 to 1.96) from area with U mineralization. It was also determined that the anthropogenic influence of the uranium was restricted to a single sampling point within the mining area.

Abstract: Geocentric translation model (GTM) in recent times has not gained much popularity in coordinate transformation research due to its attainable accuracy. Accurate transformation of coordinate is a major goal and essential procedure for the solution of a number of important geodetic problems. Therefore, motivated by the successful application of Artificial Intelligence techniques in geodesy, this study developed, tested and compared a novel technique capable of improving the accuracy of GTM. First, GTM based on official parameters (OP) and new parameters determined using the arithmetic mean (AM) were applied to transform coordinate from global WGS84 datum to local Accra datum. On the basis of the results, the new parameters (AM) attained a maximum horizontal position error of 1.99 m compared to the 2.75 m attained by OP. In line with this, artificial neural network technology of backpropagation neural network (BPNN), radial basis function neural network (RBFNN) and generalized regression neural network (GRNN) were then used to compensate for the GTM generated errors based on AM parameters to obtain a new coordinate transformation model. The new implemented models offered significant improvement in the horizontal position error from 1.99 m to 0.93 m.

Objective: This study evaluated the association between colors and emotions in a pediatric dental population. Study design: In this randomized cross-sectional study, 100 children aged 6–12 years were categorized as non-anxious and anxious using Corah's Dental Anxiety Scale–Revised. They were then instructed to color two cartoon faces, one depicting happiness emotion and the other, sadness, with any of six colors provided. Data obtained were statistically analyzed. Results: The mean Corah's Dental Anxiety scores were 11.7 and 4.97 for the anxious and non-anxious children, respectively. Both groups expressed the highest preference for the color yellow for happiness emotion. No significant differences were observed between color choices in either group (p>0.05), except for black which was not chosen by any child for happiness (p<0.005). Children in both groups significantly preferred red for sadness emotion. No significant differences were observed between color choices in the anxious group (p>0.05). In the non-anxious group, yellow assumed significant preference over green (p<0.05). Conclusions: Yellow was the most-preferred color and black, the least-preferred, for happiness emotion, whereas, for sadness emotion, red and green were the most- and least-preferred colors, respectively. Color preference was not affected by the presence of dental anxiety.
The Use of Restorative Materials in Primary Molars among Pediatric Dentists in Israel

Objectives: To assess the current choice of various restoration materials among Israeli pediatric dentists according to seniority and specialty. Study design: Participating dentists completed a 23-item questionnaire on their qualifications, type of practice and preference of restorative material. Results: Seventy-five dentists (average age 46.27±12.6 years, 58 females) participated. Forty-one were specialist pediatric dentists and 34 were general practitioners. Amalgam was preferred by 49.3%, followed by composite (41.3%), glass ionomer cement (5.3%) and compomer (4%). Only 13.3% of the dentists thought amalgam bears environmental and health hazards, compared to 49.3% for composite. Satisfaction was high for amalgam and composite, less for glass ionomer cements and least for compomer. General practitioners preferred amalgam (70.6%) while pediatric dentists preferred composite (51.2%), P < 0.003. Conclusions: Amalgam and composite were the materials of choice among the participating Israeli dentists. Most of them (86.7%) responded that amalgam does not possess any health issues. Their satisfaction with the restoration materials was highest for amalgam and composite, a choice significantly affected by whether they were in general practice (amalgam) or specialized in pediatric dentistry (composite).

Published: April 2017

Objective: To evaluate the effect of bonding strategy on microtensile bond strength (μTBS) of a new universal adhesive system to primary tooth dentin. Study design: Flat dentin surfaces from 25 primary molars were assigned to 5 groups according to the adhesive and bonding approach: Adper Single Bond 2 (two-step etch-and-rinse adhesive) and Clearfil SE Bond (two-step self-etch system), as controls; Scotchbond Universal Adhesive–self-etch, dry or wet-bonding etch-and-rinse strategies. Composite buildups were constructed and the teeth were sectioned to obtain bonded sticks (0.8 mm2) to be tested under tension at 1mm/min. The μTBS means were analyzed by one-way ANOVA and Tukey's tests (α = 0.05). Failure mode was evaluated using a stereomicroscope (400×). Results: Universal adhesive applied following both dry and wet-bonding etch-and-rinse strategies showed similar bond strength compared with control adhesive systems. Self-etch approach resulted in the lowest μTBS values. For all groups, adhesive/mixed failure prevailed. The percentage of premature debonded specimens was higher when the universal adhesive was used as self-etch mode. Conclusion: The universal adhesive does not share the same versatility of being used in the etch-and-rinse and self-etch approaches; however, the use of the new adhesive following either wet or dry-bonding may be a suitable option as alternative to two-step etch-and-rinse adhesive protocol.
