ABSTRACT The purpose of this clinical case description article was to present the planning sequence, indication, treatment and performance to obtain a crown of the Endocrown type. This clinical case description article illustrates a therapeutic option for functional and esthetic rehabilitation of a devitalized mandibular molar, presenting a small amount of remaining coronal tooth structure, by means of cementing a pure porcelain crown of the Endocrown type (Adhesive Endodontic Crown). A 39-year-old woman presented to the Graduate clinic of the Bauru Dental School (FOB), University of São Paulo (USP), with the complaint that tooth #36 had an extensive and unsatisfactory composite resin restoration. The lithium disilicate-based system of monolithic porcelain was used with the lost wax technique. This therapy promoted the stability and retention of the indirect restoration, without the need for performing reconstruction of the above mentioned tooth, either by means of a cast metal core or reconstruction with intracanal post, thereby reducing the treatment time. After the tooth preparation, the provisional restoration was done with acrylic resin to determine if the retention and stability of the remaining tooth was adequate to receive the indirect Endocrown restoration. The characteristics of the internal and external walls of the dental remnants, cervical termination, impression-taking, laboratory stages and adhesive cementation will be discussed. The major advantage of indicating an endocrown is the use of the dental remnants itself, particularly the pulp chamber, to promote retention and stability in cases without adequate height for performing complete dental and crown reconstruction.KeywordsAdhesive endodontic crown; Devitalized tooth; Lithium dissilicate.

Authors: Cunha Carlos Wallace , Rodrigues Carolina , Magri Lais Valencise , Matos Bruno Henrique Figueiredo , Bataglion Cesar , Mazzetto Marcelo Oliveira
Published: July 2016

Objective: To describe a case of unilateral TMJ osteoarthritis from the Dentistry point of view, aiming to restore the quality of life through non-invasive procedures. Description of case: M.C.B., female, 69 years, complaining about a sudden change in the bite, difficulty to chewing/opening mouth and pain in the orofacial region. At extraoral examination, we observe the presence of crepitus in the left TMJ, click in the right TMJ (electrovibratography) and pain on palpation in the left TMJ region. Absence of tooth contacts on the right side in maximum habitual intercuspation (MHI). The intraoral examination revealed the presence of inflammation and excessive wear in the left mandibular condyle (osteoarthritis), visualized by computed tomography and magnetic resonance imaging with contrast. The patient underwent treatment by oclusal splint (night use), overlay removable partial dentures (daytime use), application of lower level laser therapy and transcutaneous electrical nervous stimulation (TENS). Masticatory function, mouth opening, and aesthetics improved. Conclusion: Conservative therapies may be a good option for the re-establishment of the quality of life in subjects with TMJ osteoarthritis, inasmuch as it can postpone or delete the indication of more invasive techniques (e.g. surgery). KeywordsOsteoarthritis; Temporomandibular joint disorders; Temporomandibular joint.

Published: July 2016

Clinicians can find patients with one mandibular remaining tooth, and it is difficult to decide if the tooth has to be removed. When a clinician decide to maintaining the tooth, it is common to feel doubts about masticatory load distribution divided between the tooth and implant. This paper reports a clinical case of patient with an implant/tooth-supported overdenture and elucidates the masticatory efficiency by electromyography activity analysis. The objective of this case report was to describe a clinical case of a patient with an implant/tooth-supported overdenture and to discuss the muscle response to this treatment. Electrical activities of the masseter and anterior temporal surfaces at maximum voluntary contraction were evaluated by electromyography during pre-treatment, immediately post-treatment, 15 and 60 days after installation. When patient has one remaining tooth in good condition, the implant/tooth-supported overdenture can be recommended, to preserve the periodontal ligament and proprioception, and to minimize bone loss. Electromyography analysis showed that implant/tooth-supported overdenture is a viable treatment alternative, in muscular standpoint, when the patient has a remaining tooth with good osseous support.

Published: July 2016

Objective: In this study, the expression of the extracellular matrix proteins was immunohistochemically studied and compared with the histological grading of squamous cell carcinomas of the lower lip and tongue. Material and Methods: The lower lip carcinomas (n=12) and the tongue carcinomas (n=12) were histopathologically graduated according to Bryne’s method. The immunohistochemical technique utilized specific antibodies to collagen IV and laminin. Histopathologic and immunohistochemical analysis were carried-out on the tumoral invasive front. Results: Most of lower lip carcinomas (91.7%) was classified in lower score and all tongue carcinomas (100%) in high score malignant grade (p<0.01). Collagen type IV expression was absent in the peritumoral basement membrane in 50% of lower lip carcinomas and in 66.7% of tongue carcinomas (p=0.09). Laminin expression was absent in the peritumoral basement membrane in 66.7% of lower lip carcinomas and in 58.3% of tongue carcinomas (p=0.48). When these two glicoproteins were expressed, they showed a linear, thin and discontinuous pattern and a weak intensity of expression. Conclusion: The high score malignancy grade of the tongue carcinomas associated with the expression pattern of the studied matrix proteins. It suggests that tongue squamous cell carcinomas have more invasive potential and more aggressive biological behavior than the lower lip carcinomas. KeywordsCollagen type IV; Laminin; Carcinoma; Immunohistochemistry.

A TCFC auxiliou na conclusão dos diagnósticos, visto sua característica de tridimensionalidade, houve, algumas vezes, divergências em relação aos achados descritos na literatura, eminentemente baseados radiografias bidimensionais. Conclusão: a TCFC é de grande valia na caracterização das lesões ósseas, observa-se uma necessidade na literatura de uma abordagem específica para esta modalidade de imagens, diferente das radiográficas convencionais.
Desigualdades educacionais e socioeconómicas na população brasileira pré-universitária: Uma visão a partir da análise de dados do ENEM
Authors: Travitzki Rodrigo , Ferrão Maria Eugénia , Couto Alcino Pinto
Published: July 2016

O presente estudo examina, numa perspetiva intergeracional, a atenuação das desigualdades na distribuição da educação, bem como a relação entre desempenho educacional e atributos sociodemográficos tais como estatuto socioeconómico e raça/cor, com recurso aos dados do ENEM 2009-2012. Procede-se à aplicação do coeficiente de Gini e da curva de Lorenz e à modelação multinível dos dados referentes ao ano de 2012. As evidências indiciam a atenuação das desigualdades intergeracionais na distribuição da educação, sendo esta aferida quer pelo nível de escolaridade quer pela nota no Exame. Adicionalmente, os resultados apresentados sugerem que o progresso educacional continua a ser sensível a fatores de diferenciação de desempenho de natureza socio-espacial e racial.A análise multinível permitiu a decomposição da variância dos resultados educativos no nível de ensino pré-universitário e para diferentes UF’s, concluindo-se que a variabilidade dos resultados é maior ao nível intramunicipal do que intermunicipal e que quer as escolas quer os municípios constituem unidades relevantes para as políticas educativas. Assim, a redução destas disparidades impõe-se como problema prioritário, carecendo de investigação adicional sobre os determinantes do efeito-escola, nas dimensões intra e extraescolar, bem como a consequente reorientação de políticas visando a eficácia educacional.
Demonstrating the Value of Marketing
Authors: Hanssens Dominique M. , Pauwels Koen H.
Published: July 2016

Marketing departments are under increased pressure to demonstrate their economic value to the firm. This challenge is exacerbated by the fact that marketing uses attitudinal (e.g., brand awareness), behavioral (e.g., brand loyalty), and financial (e.g., sales revenue) performance metrics, which do not correlate highly with each other. Thus, one metric could view marketing initiatives as successful, whereas another could interpret them as a waste of resources. The resulting ambiguity has several consequences for marketing practice. Among these are that the scope and objectives of marketing differ widely across organizations. There is confusion about the difference between marketing effectiveness and efficiency. Hard and soft metrics and offline and online metrics are typically not integrated. The two dominant tools for marketing impact assessment, response models and experiments, are rarely combined. Risk in marketing planning and execution receives little consideration, and analytic insights are not communicated effectively to drive decisions. The authors first examine how these factors affect both research and practice. They then discuss how the use of marketing analytics can improve marketing decision making at different levels of the organization. The authors identify gaps in marketing's knowledge base that set the stage for further research and enhanced practice in demonstrating marketing's value.

Authors: Batra Rajeev , Keller Kevin Lane
Published: July 2016

With the challenges presented by new media, shifting media patterns, and divided consumer attention, the optimal integration of marketing communications takes on increasing importance. Drawing on a review of relevant academic research and guided by managerial priorities, the authors offer insights and advice as to how traditional and new media such as search, display, mobile, TV, and social media interact to affect consumer decision making. With an enhanced understanding of the consumer decision journey and how consumers process communications, the authors outline a comprehensive framework featuring two models designed to improve the effectiveness and efficiency of integrated marketing communication programs: a “bottom-up” communications matching model and a “top-down” communications optimization model. The authors conclude by suggesting important future research priorities.

Topochemical kinetic mechanism of cellulase hydrolysis on fast-growing tree species. COST Action FP1105
Authors: Valchev Ivo , Yavorov Nikolay , Petrin Stoyko
Published: July 2016

Optimization of the lignocellulosic bioconversion by cellulolytic enzymes requires good knowledge of reaction kinetics. In the present paper, the investigations of the kinetics have been performed on the fast-growing tree species of poplar, paulownia, willow and black locust, which were pretreated by steam explosion (SE), and bleached kraft pulp (BKP) made of a hardwood mixture. The applicability of different kinetic equations referring to diffusion, topochemical and other heterogeneous catalytic processes was examined, and it was found that the enzyme process is best described by the modified Prout-Tompkins topochemical equation. According to that kinetic model, the hydrolysis rate depends on the amount of the substrate left and the inhibition of the enzyme by the product formed and, moreover, on the combination of chemical interaction and diffusion processes. There is a compensation effect between activation energy and pre-exponential factor and there are correlations between rate constant, power factor, and wood density. The mechanisms of cellulase hydrolysis of BKP- and SE-treated fast-growing tree species are very similar. The results shows that the structural features of the lignocellulosic material are the controlling factor on the type of the kinetic mechanism. The obtained temperature-time dependence of degree of enzyme hydrolysis is useful for simulation and control of the process.
Hydrodeoxygenation of Phenol Over Sulfided CoMo Catalysts Supported on a Mixed Al2O3-TiO2 Oxide
Authors: Tavizón-Pozos J. A. , Suárez-Toriello V. A. , del Ángel P. , de los Reyes J. A.
Published: July 2016

In this work, the effect of the mixed Al2O3-TiO2 oxide (Al/Ti=2, named AT2) support on the support-metal interaction in oxide state, its influence on MoS2 dispersion and its impact on the hydrodeoxygenation of phenol reaction was studied. In contrast with CoMo/Al2O3 catalysts, the use of Al2O3-TiO2 as support tuned favorably the support-metal interaction, increasing the availability of easily reducible CoOX and MoOX species with octahedral coordination, which are recognized as precursors of the active phase. The lower support-metal interaction strength caused a decrease in the dispersion of MoS2 phase. Even so, the sulfided CoMo/AT2 catalyst reached 85 % higher catalytic activity in the hydrodeoxygenation of phenol than CoMo/Al2O3. These increases were explained in terms of the formation of a higher amount of active CoMoS phase, and it is consistent with the increased availability of cobalt promoter for the decoration of MoS2 edges. CoMo/AT2 catalyst was more resistant to inhibition by CS2 than CoMo/Al2O3 in direct deoxygenation route and hydrodeoxygenation of phenol.
Sensitivity of personal data items in different online contexts
Authors: Ortlieb Martin , Garner Ryan
Published: July 2016

We present the results of a survey study (n = 1,200) investigating online users' privacy sensitivity towards exposing
specific data items to service providers of the three most prominent online services in the UK: online retail, social
networking and information search. The study, representative of the online population of the UK, presents proof for the
context-dependence of privacy sensitivity and provides concrete quantitative results for specific data items (like full
name or mobile phone number). One of the key results is that data that is considered essential in order for a service to
work is seldomly rated as sensitive. We could also show that passively collected data is in general more sensitive than
concrete data provided by the users. However, specific conditions like control and transparency can have positive/negative
effects on the sensitivity of data in a specific context.

Holistic logical arguments in quantum computation
Authors: Chiara Maria Luisa Dalla , Giuntini Roberto , Leporini Roberto , Sergioli Giuseppe
Published: July 2016

Quantum computational logics represent a logical abstraction from the circuit-theory in quantum computation. In these logics formulas are supposed to denote pieces of quantum information (qubits, quregisters or mixtures of quregisters), while logical connectives correspond to (quantum logical) gates that transform quantum information in a reversible way. The characteristic holistic features of the quantum theoretic formalism (which play an essential role in entanglement-phenomena) can be used in order to develop a holistic version of the quantum computational semantics. In contrast with the compositional character of most standard semantic approaches, meanings of formulas are here dealt with as global abstract objects that determine the contextual meanings of the formulas’ components (from the whole to the parts). We present a survey of the most significant logical arguments that are valid or that are possibly violated in the framework of this semantics. Some logical features that may appear prima facie strange seem to reflect pretty well informal arguments that are currently used in our rational activity.
On realization of effect algebras
Authors: Niederle Josef , Paseka Jan
Published: July 2016

A well known fact is that there is a finite orthomodular lattice with an order determining set of states which is not order embeddable into the standard quantum logic, the lattice L(𝓗) of all closed subspaces of a separable complex Hilbert space.

We show that a finite generalized effect algebra is order embeddable into the standard effect algebra E(𝓗) of effects of a separable complex Hilbert space iff it has an order determining set of generalized states iff it is order embeddable into the power of a finite MV-chain.

As an application we obtain an algorithm, which is based on the simplex algorithm, deciding whether such an order embedding exists and, if the answer is positive, constructing it.

Note on a parameter switching method for nonlinear ODEs
Authors: Danca Marius-F. , Fečkan Michal
Published: July 2016

In this paper we study analytically a parameter switching (PS) algorithm applied to a class of systems of ODE, depending on a single real parameter. The algorithm allows the numerical approximation of any solution of the underlying system by simple periodical switches of the control parameter. Near a general approach of the convergence of the PS algorithm, some dissipative properties are investigated and the dynamical behavior of solutions is investigated with the Lyapunov function method. A numerical example is presented.
Commutativity in a synaptic algebra
Authors: Foulis David J. , Pulmannová Sylvia
Published: July 2016

A synaptic algebra is a generalization of the self-adjoint part of a von Neumann algebra. For a synaptic algebra we study two weakened versions of commutativity, namely quasi-commutativity and operator commutativity, and we give natural conditions on the synaptic algebra so that each of these conditions is equivalent to commutativity. We also investigate the structure of a commutative synaptic algebra, prove that a synaptic algebra is commutative if and only if it is a vector lattice, and provide a functional representation for a commutative synaptic algebra.
Nonlinear plasmonic imaging techniques and their biological applications
Authors: Deka Gitanjal , Sun Chi-Kuang , Fujita Katsumasa , Chu Shi-Wei
Published: July 2016

Nonlinear optics, when combined with microscopy, is known to provide advantages including novel contrast, deep tissue observation, and minimal invasiveness. In addition, special nonlinearities, such as switch on/off and saturation, can enhance the spatial resolution below the diffraction limit, revolutionizing the field of optical microscopy. These nonlinear imaging techniques are extremely useful for biological studies on various scales from molecules to cells to tissues. Nevertheless, in most cases, nonlinear optical interaction requires strong illumination, typically at least gigawatts per square centimeter intensity. Such strong illumination can cause significant phototoxicity or even photodamage to fragile biological samples. Therefore, it is highly desirable to find mechanisms that allow the reduction of illumination intensity. Surface plasmon, which is the collective oscillation of electrons in metal under light excitation, is capable of significantly enhancing the local field around the metal nanostructures and thus boosting up the efficiency of nonlinear optical interactions of the surrounding materials or of the metal itself. In this mini-review, we discuss the recent progress of plasmonics in nonlinear optical microscopy with a special focus on biological applications. The advancement of nonlinear imaging modalities (including incoherent/coherent Raman scattering, two/three-photon luminescence, and second/third harmonic generations that have been amalgamated with plasmonics), as well as the novel subdiffraction limit imaging techniques based on nonlinear behaviors of plasmonic scattering, is addressed.
Sensitivity of ‘Monika’ Cucumis sativus seedlings to low temperature and induction of chilling tolerance
Authors: Górnik Krzysztof
Published: July 2016

The aim of the research was to investigate the chilling sensitivity of cucumber seedlings and to alleviate its negative effects by short-term shock temperature applied during seeds imbibition, before radicle protrusion. The chilling sensitivity was investigated depending on initial root length (1, 3, 5 and 7 mm) and duration of chilling exposure (0, 1, 3, 7, 14, 21 days) at 0°C and was evaluated by measurements of roots and hypocotyls growth, electrolyte leakage and dehydrogenases activity. To assess whether short-term shock temperature applied before radicle protrusion can increase chilling tolerance in cucumber seedlings the seeds were imbibed at 25°C for 16 h, exposed to temperatures of 0; 2,5; 5; 35; 40, 45°C for 0; 0,5; 1; 2; 4 h.

The obtained results indicated that cucumber seedlings sensitivity depended on duration of chilling expo-sure and initial root length during which the seedlings were subjected to these conditions. Chilling sensitivity were manifested by drop in the roots and hypocotyls elongation, reduction in dehydrogenases activity and membrane integrity expressed by electrolyte leakage. Seedlings with 1 mm roots was relatively tolerant to 3 days of chilling at 0°C. Their chilling sensitivity increased as roots elongated. Seedling with 3, 5, 7 mm of roots subjected to chilling suffered a subsequent 71, 75 and 81% of growth inhibition, respectively.

The presented results showed that a short-term of low (0; 2,5 or 5°C) or high (35; 40 or 45°C) temperature treatments applied before radicle protrusion i.e. after 16 h of seeds imbibition significantly counteracted the negative effects of chilling on seedlings. The best results expressed by increased length and the number of roots were obtained when imbibed seeds were exposed to 45°C for 2 and 4 h. The increased chilling tolerance of cucumber seedlings induced as early as at the stage of seed imbibition, before radicle protrusion indicates on the possibility of application of this method in practice. The positive response of such treatment on cucumber chilling tolerance are discussed.

Published: July 2016

Two experiments were conducted to evaluate ageing-induced genetic changes and to establish physiological thresholds for loss of genetic integrity during ageing or storage of rice seeds. In the first experiment, seeds of 10 varieties of rice were subjected to artificial ageing in chambers conditioned to 55°C and 72±2% RH for 72 hours. In the second experiment, seeds of 4 varieties of rice stored in the NACGRAB gene bank, Nigeria in 2011 at 5± 4°C were compared with seeds of the same accessions freshly harvested in 2013. Data were collected on seed germination and seedling length to estimate the seed vigour index. Genetic changes during the ageing were evaluated by SSR markers using a Direct™ PCR kit. Genetic distance indices were computed using PAST™ software and percentage genetic integrity was estimated from the genetic distance matrices. At 72 hours of artificial ageing, seed germination percentage declined to 54.2% and vigour index 0.8 coinciding with the lowest estimate of genetic integrity of 99.5%. The decline in percentage genetic integrity during the artificial ageing indicated a systematic ageing-induced genetic alteration. SSR primer RM178 revealed variations that suggest losses of alleles in the course of ageing for 2 accessions at between 24 hours in WITA4 and 48 to 51 hours in CG14. In the gene bank storage trial, germination of seeds after one and two years of storage was above 80% and there were no significant differences among the accessions. SSR profiles for all the accessions were also similar. The result partly corroborates the artificial ageing data. This implies that seed viability benchmark of 54% is recommended for regeneration of stored rice seeds in order to maintain optimum genetic integrity during storage.

Published: July 2016

The aim of this study is investigation the applicability of SSR and ISSR markers in evaluating the genetic relationships in twenty accessions ofAegilopsandTriticumspecies with D genome in different ploidy levels. Totally, 119 bands and 46 alleles were detected using ten primers for ISSR and SSR markers, respectively. Polymorphism Information Content values for all primers ranged from 0.345 to 0.375 with an average of 0.367 for SSR, and varied from 0.29 to 0.44 with the average 0.37 for ISSR marker. Analysis of molecular variance (AMOVA) revealed that 81% (ISSR) and 84% (SSR) of variability was partitioned among individuals within populations. Comparing the genetic diversity ofAegilopsandTriticumaccessions, based on genetic parameters, shows that genetic variation ofAe. crassaandAe. tauschiispecies are higher than other species, especially in terms of Nei’s gene diversity. Cluster analysis, based on both markers, separated total accessions in three groups. However, classification based on SSR marker data was not conformed to classification according to ISSR marker data. Principal co-ordinate analysis (PCoA) for SSR and ISSR data showed that, the first two components clarified 53.48% and 49.91% of the total variation, respectively. This analysis (PCoA), also, indicated consistent patterns of genetic relationships for ISSR data sets, however, the grouping of accessions was not completely accorded to their own geographical origins. Consequently, a high level of genetic diversity was revealed from the accessions sampled from different eco-geographical regions of Iran.

Performance Analysis of Multipurpose Refrigeration System (MRS) on Fishing Vessel
Authors: Ust Y. , Sinan Karakurt A. , Gunes U.
Published: July 2016

The use of efficient refrigerator/freezers helps considerably to reduce the amount of the emitted greenhouse gas. A two-circuit refrigerator-freezer cycle (RF) reveals a higher energy saving potential than a conventional cycle with a single loop of serial evaporators, owing to pressure drop in each evaporator during refrigeration operation and low compression ratio. Therefore, several industrial applications and fish storage systems have been utilized by using multipurpose refrigeration cycle. That is why a theoretical performance analysis based on the exergetic performance coefficient, coefficient of performance (COP), exergy efficiency and exergy destruction ratio criteria, has been carried out for a multipurpose refrigeration system by using different refrigerants in serial and parallel operation conditions. The exergetic performance coefficient criterion is defined as the ratio of exergy output to the total exergy destruction rate (or loss rate of availability). According to the results of the study, the refrigerant R32 shows the best performance in terms of exergetic performance coefficient, COP, exergy efficiency, and exergy destruction ratio from among the other refrigerants (R1234yf, R1234ze, R404A, R407C, R410A, R143A and R502). The effects of the condenser, freezer-evaporator and refrigerator-evaporator temperatures on the exergetic performance coefficient, COP, exergy efficiency and exergy destruction ratios have been fully analyzed for the refrigerant R32.

Published: July 2016

Tertiary education involves specific perceived issues among PhD candidates that lead to several self-destructive behaviors regarding the research process and the quality of the doctoral thesis. Studying the emotional mechanisms behind the process of doctoral research offers useful insights for both PhD candidates and PhD supervisors. A qualitative approach involving a concept analysis method was used to investigate the concerns about the doctoral process of a group of PhD candidates enrolled in the first year at the Doctoral School of Economics and Business Administration of Iași, Romania. Both spontaneous and induced responses were considered. The order of concerns and the fact that some of them were mentioned together were also taken into account. Most of the concerns are related to time-management. Results are discussed and several recommendations are made.
Determinants of Firm Performance: Evidence from Romanian Listed Companies
Authors: Lazăr Sebastian
Published: July 2016

The paper investigates firm-specific determinants of firm profitability for Romanian listed companies over the 2000-2011 period within the framework of resource based view of the firm. The results show that tangibles, leverage, size and labour intensity have negative effect on firm performance, while sales growth and value added have a positive effect. The results prove robust when introducing two-way fixed effects model and industry year effects model (in order to simultaneously account for specific industry characteristics and time effects).
Assesing the Determinantts of Firms’ Competitiveness in Greece: A Structural Equation Modeling Analysys
Authors: Metaxas Theodore , Economou Athina
Published: July 2016

The paper investigates the importance of territorial features/assets (i.e. agglomeration economies, urban infrastructure, factors of labour and cost, development policies, qualitative factors, inter alia) on small and medium-sized firms’ competitiveness. The analysis uses primary data from 204 small and medium-sized firms located in Thessaloniki (Greece). These firms operate in the industry, commerce and services sectors. Through the use of Structural Equation Modeling (SEM) analysis, the importance of particular factors for the competitiveness of firms has been analysed, reaching valuable conclusions not only for the firms and the city of Thessaloniki, but also for the firms and areas with similar characteristics in Greece and the wider area of the Balkans.

Authors: Seitz Victoria A. , Aldebasi Nada M.
Published: July 2016

The mobile device market, particularly for smart phones, has experienced incredible growth over the past five years. What sets this market apart is the use of applications or apps for just about anything from information to purchases. The purpose of the study was to examine the effectiveness of branded apps on consumers’ attitudes toward brands as well as purchase intentions. The sample was drawn from students enrolled at a southwestern university in the United States, resulting in 50 usable questionnaires. Results of Pearson’s correlation analysis indicated that using branded apps strongly influenced users’ attitudes toward brands; however, using branded apps had a smaller impact on purchase intentions. As well, attitudes towards the branded apps, although significant, had a limited impact on purchase intentions. Implications of the findings were then discussed.

Reverse logistics, the movement of materials back up the supply chain, is recognised by many organisations as an opportunity for adding value. The paper considers the theoretical framework and the conception of reverse logistics in literature and practice. The objective of the article is to propose tangible solutions which eliminate the imbalances in reverse logistics and improve the waste management in the company. The case study focuses on the improvement in the process of waste packaging in the context of sustainable development as a part of reverse logistics in the surveyed industrial company in Slovakia.
Selected Aspects of Assessment/Improvement of Academic Research Quality, Also of Industrial Management
Authors: Jemala Marek
Published: July 2016

In terms of publishing and commercialisation of academic research results, there may be more preferred qualitative research in the long term. But, not every research can be focused only on the quality of its outputs, but each output of the research, however, should have an adequate quality and added value. The main research question of this article may be determined as follows – How can the quality of academic research be better evaluated and thus improved, also in the area of Industrial management? It is not the intention of this article to perform statistical research in the field yet, but this study is based on empirical data and results.
Rigor mortis and livor mortis in a living patient: A fatal case of acute total occlusion of the infrarenal abdominal aorta following renal surgery
Authors: Høyer Christian Bjerre , Rognås Leif , Lund Lars , Boel Lene Warner Thorup
Published: July 2016

A 63-year-old woman underwent a nephrectomy on the right side for renal cancer. Postoperatively she developed abdominal and lower back pain, which was treated with an injection of analgesics in an epidural catheter. The following morning it was discovered that the patient had cold legs with pallor and no palpable femoral pulse. Rigor mortis and livor mortis were diagnosed in both legs, even though the patient was still alive and awake. Doppler ultrasound examination revealed the absence of blood flow in the lower part of the abdominal aorta and distally. A cross disciplinary conference including specialists in urology, orthopaedics, vascular surgery, anaesthesiology, internal medicine, and intensive care concluded that no lifesaving treatment was possible, and the patient died the following day. A forensic autopsy revealed severe atherosclerosis with thrombosis and dissection of the abdominal aorta. This case clearly demonstrates that a vascular emergency should be considered when patients complain about pain in the lower back, abdomen or limbs. Clinicians should be especially aware of symptoms of tissue death that can be masked by epidural analgesia.
A three year old girl was removed from her parents because of failure to recognize Mongolian spots
Authors: Christoffersen Søren
Published: July 2016

A three year old girl was observed to have bluish marks on her back, arms and legs. The social services initiated an examination on the local hospital, but no conclusion regarding the marks was reached. The girl was institutionalized before a forensic examination after three days concluded that the marks were Mongolian spots. The case stresses the importance of being able to distinguish between Mongolian spots and skin hematomas and the need for a genuine clinical forensic examination in cases where child abuse is suspected. A guide for distinguishing between Mongolian spots and skin hematomas is presented.

Authors: Zhou Qin , Mirzazadeh M.
Published: July 2016

We presented an analytical study on dynamics of solitons for Langmuir waves in plasma physics. The mathematical model is given by the perturbed nonlinear Schrödinger equation with full nonlinearity and Kerr law nonlinearity. There are three techniques of integrability were employed to extract exact solutions along with the integrability conditions. The topological 1-soliton solutions, singular 1-soliton solutions, and plane wave solution were reported by Ricatti equation expansion approach and then the bright 1-soliton solution, singular 1-soliton solution, periodic singular solutions, and plane wave solution were derived with the help of trial solution method. Finally, based on the G′/G-expansion scheme, we obtained the hyperbolic function travelling wave solution, trigonometric function travelling wave solution, and plane wave solution.

The regenerative ability of CNS axons decreases with age, however, this ability remains largely intact in PNS axons throughout adulthood. These differences are likely to correspond with age-related silencing of proteins necessary for axon growth and elongation. In previous studies, it has been shown that reintroduction of the α9 integrin subunit (tenascin-C receptor, α9) that is downregulated in adult CNS can improve neurite outgrowth and sensory axon regeneration after a dorsal rhizotomy or a dorsal column crush spinal cord lesion. In the current study, we demonstrate that virally expressed integrins (α9, α6, or β1 integrin) in the adult rat sensorimotor cortex and adult red nucleus are excluded from axons following neuronal transduction. Attempts to stimulate transport by inclusion of a cervical spinal injury and thus an upregulation of extracellular matrix molecules at the lesion site, or cotransduction with its binding partner, β1 integrin, did not induce integrin localization within axons. In contrast, virally expressed α9 integrin in developing rat cortex (postnatal day 5 or 10) demonstrated clear localization of integrins in cortical axons revealed by the presence of integrin in the axons of the corpus callosum and internal capsule, as well as in the neuronal cell body. Furthermore, examination of dorsal root ganglia neurons and retinal ganglion cells demonstrated integrin localization both within peripheral nerve as well as dorsal root axons and within optic nerve axons, respectively. Together, our results suggest a differential ability forin vivoaxonal transport of transmembrane proteins dependent on neuronal age and subtype.
