A fault diagnosis method of rolling element bearings based on CEEMDAN
Authors: Lei Yaguo , Liu Zongyao , Ouazri Julien , Lin Jing
Published: December 2015

Ensemble empirical mode decomposition (EEMD) represents a valuable aid in empirical mode decomposition (EMD) and has been widely used in fault diagnosis of rolling element bearings. However, the intrinsic mode functions (IMFs) generated by EEMD often contain residual noise. In addition, adding different white Gaussian noise to the signal to be analyzed probably produces a different number of IMFs, and different number of IMFs makes difficult the averaging. To alleviate these two drawbacks, complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) was previously presented. Utilizing the advantages of CEEMDAN in extracting weak characteristics from noisy signals, a new fault diagnosis method of rolling element bearings based on CEEMDAN is proposed. With this method, a particular noise is added at each stage and after each IMF extraction, a unique residue is computed. In this way, this method solves the problem of the final averaging and obtains IMFs with less noise. A simulated signal is used to illustrate the effectiveness of the proposed method, and the decomposition results show that the method obtains more accurate IMFs than the EEMD. To further demonstrate the proposed method, it is applied to fault diagnosis of locomotive rolling element bearings. The diagnosis results prove that the method based on CEEMDAN may reveal the fault characteristic information of rolling element bearings better.

Syphilis can be transmitted by pregnant women to their children and is a public health problem in Africa. A cross-sectional survey was conducted in 24 antenatal clinics from 2002 to 2003 and increased to 30 sites from 2005 to 2011. Participants were tested for syphilis and HIV. Multi-variate logistic regression was performed to identify risks associated with syphilis and its co-infection with HIV. Results showed that syphilis decreased from 3.8% in 2002 to 2.0% in 2011. Syphilis in the HIV-infected participants increased from 6.0% in 2002 to 10.8% in 2011, but decreased from 3.7% to 1.7% in the HIV-negative participants. In 2011, syphilis in urban participants was 2.7% and 1.4% in rural ones. HIV-infected participants screened positive for syphilis more frequently in both rural (aOR = 3.64 [95% CI: 1.56%–8.51%]) and urban areas (aOR = 7.26 [95% CI: 5.04%–10.46%]). Older participants (25–49 years) residing in urban areas (aOR = 0.43[95% CI: 0.32%–0.58%]) and women with secondary or high education (aOR = 0.35[95% CI: 0.20%–0.62%]) were less likely to screen positive for syphilis. HIV-syphilis co-infection was more likely in women residing in urban areas (aOR = 8.32[95% CI: 3.54%–19.56%]), but less likely in women with secondary/high education (aOR = 0.11[95% CI: 0.01%–0.77%]). In conclusion, syphilis increased in HIV-positive pregnant women, but decreased in HIV-negative women. Positive HIV status and young age were associated risks for syphilis. HIV-syphilis co-infection was associated with a lower level of education and urban residence.
Bistable compliant mechanism using magneto active elastomer actuation
Authors: Crivaro Adrienne , Sheridan Robert , Frecker Mary , Simpson Timothy W , Von Lockette Paris
Published: December 2015

One of the challenges in the emerging field of origami engineering is achieving large deformations to enable significant shape transformations. Bistable compliant mechanisms provide a means to achieve this, and the goal of this research is to investigate the feasibility and design of a compliant bistable mechanism that is actuated by magneto active elastomer material. When exposed to an external field, magneto active elastomer material deforms to align embedded magnetic particles with the field. We investigate a case study using magneto active elastomer actuation through the development of finite element analysis models to predict the magnetic field required to snap the device from its first stable position to its second for various geometries and field strengths. The finite element analysis model also predicts the displacement of the mechanism as it moves from one position to the other to determine whether the device is in fact bistable. These results can be used to understand the relationship between the substrate properties and the bistability of the device. The experimental results validate the finite element analysis models and demonstrate the functionality of active magneto active elastomer materials to be used as actuators for such devices and applications of origami engineering.
Dynamic characteristics and control of magnetorheological/electrorheological sandwich structures: A state-of-the-art review
Authors: Eshaghi Mehdi , Sedaghati Ramin , Rakheja Subhash
Published: December 2015

During past four decades, applications of magnetorheological and electrorheological fluids in adaptive sandwich structures have been widely studied, primarily for the purpose of vibration control. The rapid response time of controllable magnetorheological/electrorheological fluids to an applied magnetic/electric field and reversible variations in their stiffness and damping properties have been the key motivations for adaptive structures applications. This article presents a comprehensive review of the reported studies on applications of magnetorheological/electrorheological fluids for realizing active and semi-active vibration suppression in sandwich structures. The review focuses on methods of characterizing the magnetorheological/electrorheological fluids in the pre-yield region, magnetic/electric field-dependent phenomenological models describing the storage and loss moduli of fluids, experimental and analytical methods developed for vibration analysis of sandwich structures with magnetorheological/electrorheological fluid treatments, analysis of structures with partial magnetorheological/electrorheological fluid treatments and optimal treatment locations, and developments in control strategies for vibration suppression of magnetorheological/electrorheological sandwich structures. The studies on dynamic responses of fully and partially treated magnetorheological/electrorheological-based sandwich beams, plates, shells, and panels are also discussed, including the mathematical modeling methods and associated assumptions, methods of solutions, and experimental methods.
First Pharmacological Therapy for Hypoactive Sexual Desire Disorder in Premenopausal Women
Authors: Robinson Kristin , Cutler Jasmine B. R. , Carris Nicholas W.
Published: December 2015

Objective: To review data regarding flibanserin, a recently approved therapy for hypoactive sexual desire disorder (HSDD). Data Sources: Literature search of MEDLINE (September 1995 to November 2015) was performed using the search term flibanserin. Reference lists from included articles were reviewed for pertinent citations. Study Selection and Data Extraction: We included phase-3 trials of flibanserin as a treatment for HSDD. Four reports of phase-3 trials were included. One extension study of four phase-3 trials and one phase-2 pharmacokinetic trial were also included. Data Synthesis: Though a strong placebo response was demonstrated, flibanserin consistently, yet marginally, showed improvement (compared with placebo) in the number of satisfying sexual events per month. The most common adverse events were dizziness (11.4%), somnolence (11.2%), nausea (10.4%), fatigue (9.2%), insomnia (4.9%), and dry mouth (2.4%). Conclusions: Flibanserin is effective in the treatment of HSDD. Flibanserin should be administered at bedtime to limit the risk for hypotension/syncope, accidental injury, and central nervous system (CNS) depression. Concomitant alcohol use contributes to significant CNS depression and hypotension/syncope with flibanserin and should be avoided according to the boxed warning. Careful patient assessment prior to the diagnosis of HSDD and the use of flibanserin is needed for safe use. Prescribing guidelines recommend discontinuing flibanserin at 8 weeks in the absence of benefit. Sexual dysfunction should be addressed in a patient-specific manner. Providers should exercise shared decision making in prescribing flibanserin for HSDD and discuss flibanserin’s benefits and alternative options.
Why adjuvant chemotherapy for stage III colon cancer was not given: Reasons for non-recommendation by clinicians or patient refusal
Authors: Gilbar Peter , Lee Andrew , Pokharel Khageshwor
Published: December 2015

Aim

The aim of our study was to evaluate stage III colon cancer patients discussed at a multidisciplinary team meeting to identify reasons for clinicians not recommending adjuvant chemotherapy and reasons for patients declining recommended chemotherapy.

Methods

A retrospective, single institution Australian study was conducted on all surgically managed stage III colon cancer patients diagnosed at the regional cancer centre at Toowoomba Hospital between July 2010 and December 2014. Reasons why adjuvant chemotherapy was not recommended by the multidisciplinary team or following referral to a medical oncologist and patients’ reasons for refusing chemotherapy despite medical oncology recommendation were determined.

Results

One hundred and nine patients were suitable for evaluation. Overall, 72 (66.1%) received adjuvant chemotherapy. Chemotherapy was not recommended in 25 (23.4%) of patients, with the majority (68%) having more than one cited reason. Multiple comorbidities and advanced age were the most common reasons for non-recommendation ( p < 0.01). Age alone was not a reason for not recommending chemotherapy. Twelve (11%) patients declined offered chemotherapy. The reasons for refusal were not detailed in the majority of patient charts (63.6%). Travel distance was not a factor in accepting or refusing chemotherapy.

Conclusion

Discussion at a multidisciplinary team meeting facilitates the identification of patients unsuitable for adjuvant treatment. The reasons for declining offered chemotherapy need to be assessed fully to ensure that patients’ treatment preferences are balanced against the proven benefits of chemotherapy. Attendance at a regional cancer centre provides the opportunity for high standard care in the management of stage III colon cancer.

Published: December 2015

In this paper, the free vibration and buckling analyses of the cylindrical sandwich panel with magneto-rheological fluid layer for simply supported boundary conditions was performed based on an improved higher order sandwich panel theory. This paper deals with investigation of the effects of magnetic field, geometrical parameters such as the core thickness to the panel thickness ratio, MR layer thickness to the panel thickness ratio and the fiber angle on the natural frequencies, loss factors and buckling loads corresponding to the first four mode shapes. In order to validate the results obtained from the present study, the cylindrical sandwich panel was simulated and analyzed in finite element software ABAQUS. A good agreement was observed between the results of present method and those extracted from simulation.
Examining STEM Bachelor’s Degree Completion for Students With Differing Propensities at College Entry
Authors: Wolniak Gregory C.
Published: December 2015

The study utilized data from the Beginning Postsecondary Students Longitudinal Study (BPS:04/09) to examine factors that affect 4-year college students’ likelihoods of completing a science, technology, engineering, or mathematics (STEM) bachelor’s degree within 6 years of entering college. Results highlight the lasting influence of high school academic achievement, the importance of declaring a STEM major early in a student’s college career, and disparate effects of academic performance and levels of social and academic integration. The findings suggest that students who initially may not be oriented toward STEM fields upon entering college may particularly benefit from receiving information on and encouragement toward STEM programs of study during their first year of college.
The Imitation Game and the Nature of Mixed Methods
Authors: Collins Harry , Evans Robert , Weinel Martin , Lyttleton-Smith Jennifer , Bartlett Andrew , Hall Martin
Published: December 2015

We describe the Imitation Game, a new research method that collects both qualitative and quantitative data, and which can be used as a mixed methods procedure in many disciplines. Drawing on two projects, one investigating gender, the other sexuality, we show that the quantitative and qualitative aspects of the Game combine in four different ways, from more quantitative to more qualitative, involving increasing cultural understanding by the researchers. Crucially, deep cultural input is initially supplied by the players of the Game, who act as “proxy researchers,” enabling data to be gathered quickly and efficiently. The analysis has its roots in sociology of scientific knowledge and studies of expertise and experience, hence the emphasis on the cultural foundations of methods and the nature of expertise.

Background

Melanoma is an aggressive skin cancer and a predominant cause of skin cancer-related deaths. A previous study has demonstrated the ability of butein to inhibit tumor proliferation and invasion. However, the anti-metastatic mechanisms and in vivo effects of butein have not been fully elucidated.

Methods

MTT cell viability assays were used to evaluate the antitumor effects of butein in vitro. Cytotoxic effects of butein were measured by lactate dehydrogenase assay. Anti-migratory effects of butein were evaluated by two-dimensional scratch and transwell migration assays. Signaling transduction and VEGF-releasing assays were measured by Western blotting and ELISA. We also conducted an experimental analysis of the metastatic potential of tumor cells injected into the tail vein of C57BL/6 mice.

Results

We first demonstrated the effect of butein on cell viability at non-cytotoxic concentrations (1, 3, and 10 μM). In vitro, butein was found to inhibit the migration of B16F10 cells in a concentration-dependent manner using transwell and scratch assays. Butein had a dose-dependent effect on focal adhesion kinase, Akt, and ERK phosphorylation in B16F10 cells. Butein efficiently inhibited the mTOR/p70S6K translational inhibition machinery and decreased the production of VEGF in B16F10 cells. Furthermore, the in vivo antitumor effects of butein were demonstrated using a pulmonary metastasis model.

Conclusion

The results of the present study indicate the potential utility of butein in the treatment of melanoma.

Background

Dacrocystorhinostomy (DCR) is an operation used to treat nasolacrimal duct obstruction. Essentially there are two approaches: external and endoscopic. Several modalities are used in endoscopic DCR; all aiming to improve success rate, reduce complications, and shorten operative time. Both kerrison punch and drill are widely used in endoscopic DCR with non-conclusive knowledge about differences in operative details as well as on the outcome. The aim of this study is to compare between powered (drill) and non-powered (kerrison punch) DCR to clarify the superiority of one over the other.

Methods

A retrospective chart review of 59 patients who underwent endoscopic DCR procedure at our institution from June 2013 until July 2014 (34 kerrison punch and 32 powered drill). Operative details, surgical outcome and complications were compared between both groups.

Results

A total of 66 endoscopic DCRs were performed on 59 patients. Procedure success rate among kerrison punch group was 87.88 % vs. 90.9 % in powered drill group ( p = 0.827), while complications for both groups were statistical not significant ( p = 0.91). The mean operating time among kerrison punch group was significantly lower than in powered drill group (75 min vs. 125 min, p = 0.0001).

Conclusion

Kerrison punch showed significant reduction in operating time when compared to powered drill for endoscopic DCR. No statistically significant difference was found between both groups regarding procedures’ success rate and complication.

Authors: Gargiulo Antonio R. , Feltmate Colleen , Srouji Serene S.
Published: December 2015

Background

Conventional single-incision laparoscopic surgery has been successfully employed for treatment of ovarian endometriomas. However, this technique presents surgeons with formidable ergonomic challenges, that make its widespread adoption unlikely. Robotic assistance in single-incision laparoscopic surgery provides adequate instrument triangulation through a single fulcrum, while eliminating ergonomic challenges to the surgeon. The objective of this video is to describe a novel technique of laparoscopic excision and ablation of ovarian endometriomas with single-site robotic assistance. Footage from a single surgical case is shown in our video. The da Vinci Si surgical system with da Vinci Single-Site platform was utilized. A flexible CO2 laser fiber was employed as the main energy tool.

Interrelationships of Marcellus Shale gas production to frac-induced microseismicity, interpreted minor faults and fractures zones, and stimulated reservoir volume, Greene County, Pennsylvania
Authors: Wilson Thomas H. , Hart Ariel K. , Sullivan Pete
Published: December 2015

The data we analyzed are from a Marcellus Shale gas field in Greene County, southwestern Pennsylvania. We first investigated the relationship between microseismic event trends and discontinuities extracted from 3D seismic data and their relationship to [Formula: see text]. This analysis was followed by an examination of the relationship of cumulative gas production to radiated energy, stimulated reservoir volume (SRV), and energy density (ED). We have determined that microseismic event trends observed in multiwell hydraulic fracture treatments were similar to the trends of interpreted small faults and fracture zones extracted from 3D seismic coverage of the area. Hydraulic fracture treatments conducted in six laterals produced clusters of microseismic events with an average trend of N51°E and, to a more limited extent, N56°W. The N51°E microseismic event trend coincided closely with the average N52°E trend of interpreted minor faults and fracture zones extracted from the 3D seismic data. That relationship suggested that microseismic events form through reactivation of old faults and fracture zones in response to an easterly trending [Formula: see text]. We also found that variations in gas production correlated with variations in radiated microseismic energy ([Formula: see text] of 0.985), SRV ([Formula: see text] of 0.974), and ED ([Formula: see text] of 0.989). SRV is a measure of the volume of space occupied by induced microseismicity, whereas energy release per unit volume (ED) can be directly related to rupture area created through hydraulic fracture stimulation. We suggest that ED serves as a better estimator of production potential in unconventional shale reservoirs.
Counting processes with Bernštein intertimes and random jumps
Authors: Orsingher Enzo , Toaldo Bruno
Published: December 2015

In this paper we consider point processes Nf (t), t > 0, with independent increments and integer-valued jumps whose distribution is expressed in terms of Bernštein functions f with Lévy measure v. We obtain the general expression of the probability generating functions Gf of Nf, the equations governing the state probabilities pkf of Nf, and their corresponding explicit forms. We also give the distribution of the first-passage times Tkf of Nf, and the related governing equation. We study in detail the cases of the fractional Poisson process, the relativistic Poisson process, and the gamma-Poisson process whose state probabilities have the form of a negative binomial. The distribution of the times of jumps with height lj () under the condition N(t) = k for all these special processes is investigated in detail.
On the singular components of a copula
Authors: Durante Fabrizio , Fernández-Sánchez Juan , Trutschnig Wolfgang
Published: December 2015

We analyze copulas with a nontrivial singular component by using their Markov kernel representation. In particular, we provide existence results for copulas with a prescribed singular component. The constructions not only help to deal with problems related to multivariate stochastic systems of lifetimes when joint defaults can occur with a nonzero probability, but even provide a copula maximizing the probability of joint default.
Erratum to: Mixture representations of residual lifetimes of used systems
Authors: Kamińska-Zabierowska Maria , Navarro Jorge
Published: December 2015

We have found a mistake in the proofs of Navarro (2008, Theorem 2.3(b) and 2.3(c)) due to misapplication of properties of hazard rate and likelihood ratio orders. In this paper we show with an example that the stated results do not hold. This example is interesting since it proves some unexpected properties for these orderings under the formation of coherent systems. The result stated in Navarro (2008, Theorem 2.3(a)) for the usual stochastic order is correct.
The Antibody Two-Step Solution

Published: December 2015

Problems with antibody quality have been described in numerous recent publications.  In the present commentary it is argued that these quality problems are due primarily to issues of antibody variability and antibody validation.  Further it is argued that the problem of antibody variability must be solved before validation can be useful.  A two-step solution to the antibody problem is thus proposed.
Linguo-Intercultural Sensitivity and its Predictors in EFL in a Bosnian Sample
Authors: Aydogan Hakan , Akbarov Azamat
Published: December 2015

In this article, the predictive power of five variables relevant for Linguo-intercultural sensitivity (flexibility) is examined. Communication aspect of intercultural interactions, specifically, the role of English as an international language are emphasized. Attitudes Towards English and Its Usage Scale (ATEUS) was applied to 194 students who attended to international colleges and schools in Sarajevo, Bosnia and Herzegovina. The results suggest that almost all variables are mutually correlated. The findings also reveal Verbal expressiveness and Verbal abilities as statistically significant predictors of linguo-intercultural sensitivity. Other predictors (English competence and Emotional attitudes) do not significantly contribute to explaining Linguo-intercultural variance.
South Asian women’s experience of abuse by female affinal kin: a critique of mainstream conceptualisations of ‘domestic abuse’
Authors: Mirza Nughmana
Published: December 2015

Mainstream conceptualisations of domestic abuse that focus on an intimate relationship within a nuclear household do not reflect the experiences of abuse of many women, and this is particularly evident when exploring South Asian women’s experiences of family abuse. Drawing on the experiences of 11 Pakistani Muslim women interviewed for my doctoral research, I elucidate the role of the mother-in-law in instigating and perpetrating abuse against daughters-in-law. The sociocultural norms in extended family households, such as a preference for sons and maintaining a joint virilocal household, can cause tensions and hostility between mothers- and daughters-inlaw. These tendencies have potential for violence that is best understood as everyday practices of power and control. I argue that policy and practice, and research, must incorporate a deeper understanding of the family as a potential source of abuse, and particularly the role of female affinal kin, if women are to be protected from such abuse.
Optimum currency areas, real and nominal convergence in the European Union
Authors: Andrade João Sousa , Duarte António Portugal
Published: December 2015

It is well known and widely accepted by economists that the characteristics of the countries of the European Monetary Union (EMU) created in 1999 did not match the requirements of an Optimum Currency Area (OCA). The only criteria for membership of the EMU were nominal. A strict level of convergence in inflation and interest rates was imposed. In addition to the nominal convergence, a process of convergence of nominal and real incomes in the new monetary area was expected to be generated with the monetary integration. After summarizing the criteria for a successful currency area in the context of the OCA theory, we study the real and nominal convergence process for an older group of countries (11) to establish whether or not these countries satisfy the conditions of an OCA. We apply ADF tests, together with the Schmidt-Phillips tests, and we estimate the fractional differential process to overcome the disadvantages of the traditional tests, to test for nominal and real convergence. We conclude that a process of real divergence and nominal convergence does exist, and suggest this is a source of genuine imbalance in the European integration process that can destroy the harmonious development of the European Monetary Union.http://dx.doi.org/10.14195/2183‑203X_42_1

El objetivo de esta investigación es explorar los cambios vividos por los pescadores en Bahías de Huatulco, después de la expropiación de los terrenos comunales por parte del gobierno federal, para efectos de desarrollar un Centro Turístico planificado. Con el método de la historia oral se responde ¿qué paso con las familias que vivían en este lugar, que se dedicaban a la pesca y agricultura?, ¿qué paso con los pescadores, cuál fue su destino, durante y después de la expropiación? ¿qué grado de cohesión social presentan, para enfrentarse al turismo como grupo?. El reconocimiento de sus voces supone la oportunidad de reflexionar sobre temas y situaciones que no suelen ser mencionados en los discursos ni en las fuentes oficiales.En general se observó que los pescadores fueron dependientes de los cambios nacionales de desarrollo y su percepción de los cambios históricos, es ajena a los procesos económicos y políticos macro. Aunque identifican de forma general a actores políticos y los responsabilizan de las transformaciones. Asimismo, independiente a las diversas cooperativas y los roces entre ellas, se identifica cohesión de grupo (Cruz, 2008) para justificar actuaciones y formas de ser (rasgos de identidad comunitaria (Molina, 1994) y una fuerte consistencia como grupo ante agentes externos.

Why the Post-growth Debate Is Not a Wrong Turn
Authors: Loske Reinhard
Published: December 2015

In their paper Jakob and Edenhofer (2014) argue that reflecting on conßicts between “degrowth” and “green growth” concepts is a useless thing. Instead of discussing the growth issue it would make much more sense to focus on what they call a “welfare
diagnostics” approach that deßnes minimum requirements for basic needs. No doubt, this approach has its merits. It is more or less similar to the UN’s Sustainable Development Goals. But since the authors leave out real-world conßicts and interests as well as the economic
drivers of growth, capital accumulation and consumerism, their approach appears quite apolitical. To keep quiet about growth imperatives and their compulsive dimensions is not an adequate answer to the challenges of sustainability.
Changes of gait characteristics in a child with femoral nerve injury: a 16-month follow-up case study
Authors: Hwang Seonhong , Park Jeong-Mee , Kim Youngho
Published: December 2015

An 11-year-old child was able to walk independently even though he had injured his femoral nerve severely due to a penetrating wound in the medial thigh. In this study, gait analysis was conducted five times totally for 16 months to observe the characteristics of the gait parameters, which enabled him to walk independently. The cadence, walking speed, stride length, step length, stride time, step time, double limb support, and single limb support all improved after the third test (GA3). Insufficient knee flexion during the stance phase, that was the main problem of the subject, improved from 0.96° to the normal level of 17.01°. Although hip extension was also insufficient at the first test it subsequently improved and reached the normal range at the GA5. The peaks of the ground reaction force curve were low at the initial tests. However, these eventually improved and reached the reference values. The knee extensor moment during the stance phase increased markedly at the last test. Although the child lost his femoral nerve function, he was able to walk independently by compensating for the major function of the rectus femoris. In order to facilitate shock-absorption and move the feet forward, he reduced both gait speed and stride length, respectively. The results of this study are expected to provide insight into how clinicians set up their therapy goals, while considering compensations and changes over time.

Published: December 2015

Background: It is common practice for patients with prosthetic cardiac devices, especially heart valve prosthesis, arterial stents, defibrillators, and pacemaker devices, to use anticoagulation treatment. When these patients suffer from multiple trauma after motor vehicle accidents, the best medical management for this challenging position is mandatory. This strategy should include a rapid diagnosis of all possible multiple organ injuries, with special attention to anticoagulation therapy so as to minimize the risk of thromboembolism complication in prosthetic devices. In this review, we describe the best medical management for patients with multiple trauma who use anticoagulants after heart valve replacement.
Methods: We searched electronic databases PubMed/Medline, Scopus, Embase, and Google Scholar using the following terms: anticoagulant, warfarin, heparin, and multiple trauma. Also, similar studies suggested by the databases were included. Non-English articles were excluded from the review.
Results: For patients who use anticoagulation therapy, teamwork between cardiac surgeons, general surgeons, anesthesiologists, and cardiologists is essential. For optimal medical management, multiple consults between members of this team is mandatory for rapid diagnosis of all possible damaged organs, with special attention to the central nervous system, chest, and abdominal traumas. With this strategy, it is important to take note of anticoagulation drugs to minimize the risk of thromboembolism complications in cardiac devices.
Conclusion: The best anticoagulant agents for emergency operations in patients with multiple trauma who are using an anticoagulant after heart valve replacement are fresh frozen plasma (FFP) and prothrombin complex concentrates (PCC).

The object of this research is to identify the effects of environmental tax reforms conducted in the European Union states and to show the potential benefits to Lithuania. Our research shows that environmental tax reforms raised both positive and negative effects. It is worth mentioning that these effects are more positive than negative. The majority of these effects depends on the type of tax reform. Reform effects occur within the "double dividend", by shifting the tax burden, improving the environmental situation and seeking sustainable development goals. Positive effects are revealed in long-term period. However, the short term effects remain negative. The implementation of environmental tax reform in Lithuania could be achieved by significant increase in tax revenues, which would have positive influence on the state, people, business and environment.

In recent decades the continuous decline of the rural population permanently raise concerns about the rural vitality – rural traditions, values and way of life of the rural population, which need to be supported. This is treated as a public good. Rural population is vital factor. Numerous scientific studies are devoted for investigating the ways and incentives how to encourage them to stay. The scientific problem of the study was to identify the factors behind the population variation trends in the same municipality while in some wards it increased and decreased in others. The study experts were executives of rural wards, who ranks the factors in order of importance in determining of the population trends. The results showed that executives consider population decline due to the changed geopolitical situation in Lithuania related to the accession to the EU, while the growth is caused by ward’s proximity to the central municipal city, favorable environment and availability of community gardens, where citizens are moving.

Phytoplankton composition in lotic environments has received less attention than that of lentic environments. The aim of the present study was to describe the micro-phytoplankton of the Contas River, which is one of the five most important water bodies in the state of Bahia, Brazil. Collections were carried out at 28 sampling sites at three-month intervals over a three-year period between December 2007 and September 2010. The micro-phytoplankton community was represented by 198 taxa distributed among Bacillariophyceae, Coscinodiscophyceae, Cyanophyceae, Fragilariophyceae, Chlorophyceae, Euglenophyceae, Dinophyceae, Cryptophyceae, Chrysophyceae and Xantophyceae. Geitlerinema amphibium (C. Agardh) Anagnostidis, Planktothrix agardhii (Gom.) Anagnostidis and Komárek, Pleurosira laevis (Ehrenberg) Compère and Ulnaria ulna (Nitzsch) P. Compère occurred in all samples. The majority of species (n = 111; 56.06% of the taxa) were classified as rare in the Contas River, as these organisms were only recorded during one or two months.
Amphibia, Anura, Hylodes babax Heyer, 1982 (Hylodidae), Dendropsophus ruschii (Weygoldt and Peixoto, 1987) and Bokermannohyla ibitipoca (Caramaschi and Feio, 1990) (Hylidae): Distribution extension and geographic distribution map

Para alcançar o sucesso e a longevidade da prótese dentária são de extrema importância a adaptação, o acompanhamento e a orientação profissional acerca dos cuidados com a desinfecção e a higienização das mesmas. O acúmulo do biofilme sobre as estruturas da prótese podem desenvolver lesões patológicas na mucosa, como a candidíase oral, estomatite protética, além de desenvolver halitose, cálculos salivares e pigmentação. Esta revisão da literatura objetivou apresentar protocolos de higienização e próteses removíveis, a fim de contribuir e orientar os profissionais da Odontologia quanto à escolha dos métodos de higienização de próteses dentárias. A revisão de literatura esteve pautada em artigos científicos publicados em diferentes base de dados (PubMed, Medline, Scielo, Bireme e Google Acadêmico). Foram selecionados artigos relevantes entre 2005 a 2015 referente a temática em revisão. O método combinado é a alternativa de higienização de eleição para as próteses, por ser de fácil execução, viável e pouco dispendiosa, atuando na remoção do biofilme e na preservação do material de confecção das mesmas.

En función de ello se indaga sobre el proceso de innovación en dicha actividad; el papel de las competencias técnicas y organizacionales en este proceso; las particularidades de la organización del trabajo y su influencia en el desarrollo de capacidades y resultados de innovación; las vinculaciones y su incidencia en la propensión a innovar y capacidades de la firma. Se seleccionó una empresa de software dinámica de la ciudad de Córdoba y se estudiaron de modo cualitativo y comparativo dos proyectos tecnológicos innovadores. El marco teórico de referencia está basado centralmente en la nueva literatura sobre Economía del Conocimiento, en particular, en antecedentes de investigación sobre un tipo especial de servicios que en las últimas décadas ha generado un interés creciente: Knowledge Intensive Business Services (KIBS), caracterizados por producir insumos inmateriales intensivos en conocimiento para los procesos de negocio en otras organizaciones que dependen fuertemente del conocimiento profesional. Entre ellos, el sector de SSI es uno de los más innovadores en países desarrollados y también en algunas economías emergentes. En este contexto, cobra relevancia un estudio que profundice en la naturaleza misma del proceso innovador en empresas de SSI. Ello puede generar aportes significativos al diseño de instrumentos de medición de la innovación que se encuentran en diversos estadios de desarrollo y prueba.AbstractThe objective of the paper is to analyze the innovation and capacity building process in the software production in Argentina, throw a deep unique case study.
