A relação entre nomes gerais e pronomes indefinidos na fala mineira
Authors: Oliveira Fernanda Carla
Published: June 2015

Esta pesquisa tem como objetivo analisar a relação entre os nomes gerais coisa, negócio, trem, cara, pessoa e indivíduo e os pronomes indefinidos algo, alguém, nada e ninguém no português brasileiro. Nomes gerais são definidos por Halliday e Hasan (1976) como um caso limítrofe entre um item lexical e um item gramatical, por serem semanticamente generalizados. Além de Halliday e Hasan (1976), outros trabalhos que contemplam o estudo dos nomes gerais são os de Mihatsch (2006) e Koch (2004). Sobre pronomes indefinidos, tomou-se como base Neves (2000), Mihatsch (2006) e Haspelmath (1997). A partir de um corpus de doze gravações orais feitas na cidade de Caeté-MG, com pessoas heterogêneas, buscou-se observar o número de ocorrências dos nomes gerais, bem como analisá-los, focando na relação que eles mantêm com os pronomes indefinidos. Esses dados fazem parte de um corpus maior pertencente ao projeto “O uso dos nomes gerais nos falares mineiros”. No presente trabalho constatou-se que quando o falante opta por falar da inexistência de algo e de alguém, são usadas apenas as formas pronominais nada e ninguém. Para se falar da existência de algo, utiliza-se preferencialmente coisa. Para se falar da existência de uma pessoa, há alternância entre pronome e nome geral.Abstract This research aims to analyze the relation between the general nouns coisa, negócio, trem, cara, pessoa and indivíduo and the indefinite pronouns algo, alguém, nada and ninguém in Brazilian Portuguese. General nouns are defined by Halliday and Hasan (1976) as a borderline case between a lexical item and a grammatical item, semantically generalized. Besides Halliday and Hasan (1976), other researches that contemplate the study of general nouns are Mihatsch (2006) and Koch (2004). In what concerns the indefinite pronouns, it was considered the concepts on Neves (2000), Mihatsch (2006) and Haspelmath (1997). Thus, we searched, from a corpus of twelve oral recordings made in the city of Caeté-MG, formed by from heterogeneous people, to observe the number of occurrences of general nouns, as well as analyze them, focusing on the relation they have to the indefinite pronouns. These data are part of a larger corpus belonging to the project "O uso dos nomes gerais nos falares mineiros". In the present work, it was found that when the speaker chooses to speak of the absence of algo and alguém, are used only the pronoun forms nada and ninguém. To speak of the existence of algo, it is used preferably coisa. To speak of the existence of a person, there is an alternation between the pronoun and the general noun.

Published: June 2015

The aim of this study was to quantify the morphological variation of
nectaries among 14 populations of Jovibarba heuffelii based on multivariate
statistics, and to establish whether nectaries possess taxonomic significance
for differentiating taxa within the J. heuffelii complex. To this end, we
measured the width of the nectary, its height, the angle between the carpels
and nectary, the shape of the nectary and the distance between nectaries were
measured and analyzed. Descriptive statistics, the Tukey HSD (honest
significant difference) of homogenous groups for the unequal N post-hoc test,
canonical discriminant analysis (CDA) and multiple correspondence analysis
(MCA) were used. Morphometric analysis showed that the quantitative and
semiquantitative characteristics of nectaries in the J. heuffelii complex are
highly morphologically variable, both within and between populations, and
that they are unreliable as taxonomic characters for taxon differentiation
within the J. heuffelii complex.

Published: June 2015

Aspartame (ASP) is one of the most widely used nonnutritive sweeteners. This
study investigates the chronic effects of ASP on hematological and
biochemical parameters, and its effects on the oxidative/antioxidative status
in the red blood cells of Wistar albino rats. Rats were provided with ASP (40
mg/kg/daily for six weeks) in drinking water. Increased food and fluid intake
was observed in the ASP-treated rats. Total body mass was significantly
decreased in the ASP-treated rats. Treatment with ASP caused an increase in
the concentrations of glucose, cholesterol, LDL-cholesterol, and in the
activities of alanine aminotransferase (ALT), aspartate aminotransferase
(AST) and lactate dehydrogenase (LDH), as well as a decrease in the levels of
HDL-cholesterol in the serum. A significant decline in the number of white
blood cells (WBC) was observed after ASP uptake. Based on the results we
conclude that ASP induces oxidative stress, observed as an alteration of the
glutathione redox status, which leads to increased concentrations of nitric
oxide (NO) and lipid peroxides (LPO) in the red blood cells. Changes in
biochemical parameters, lipid metabolism, as well as changes in the levels of
oxidative stress markers and the appearance of signs of liver damage indicate
that chronic use of ASP can lead to the development of hyperglycemia,
hypercholesterolemia and associated diseases.
Optimal force magnitude loaded to orthodontic microimplants: A finite element analysis
Authors: Alrbata Raed H. , Momani Moath Q. , Al-Tarawneh Ahmad M. , Ihyasat Ayman
Published: June 2015

Objective: 

To find an optimal force that can be loaded onto an orthodontic microimplant to fulfill the biomechanical demands of orthodontic treatment without diminishing the stability of the microimplant.

Materials and Methods: 

Using the finite element analysis method, 3-D computer-aided design models of a microimplant and four cylindrical bone pieces (incorporating cortical bone thicknesses of 0.5, 1.2, 2.0, and 3.0 mm) into which the microimplant was inserted were used. Various force magnitudes of 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 N were then horizontally and separately applied to the microimplant head as inserted into the different bone assemblies. For each bone/force assembly tested, peak stresses developed at areas of intimate contact with the microimplant along the force direction were then calculated using regression analysis and compared with a threshold value at which pathologic bone resorption might develop.

Results: 

The resulting peak stresses showed that bone pieces with thicker cortical bone tolerated higher force magnitudes better than did thinner ones. For cortical bone thicknesses of 0.5, 1.2, 2.0, and 3.0 mm, the maximum force magnitudes that could be applied safely were 3.75, 4.1, 4.3, and 4.45 N, respectively.

Conclusions: 

For the purpose of diminishing orthodontic microimplant failure, an optimal force that can be safely loaded onto a microimplant should not exceed a value of around 3.75–4.5 N.
Design Competition for the Fonciére Palace, Andrássy Avenue, Budapest – A Pivotal Moment
Authors: Székely Márton , Marótzy Katalin
Published: June 2015

The subject of this article is the building history and urban significance of the former ‘Fonciére Palace’1 at 2 Andrássy Avenue, Budapest. It is a five-storey building facing three streets, built in neo-renaissance style in 1882. It became a listed building in 2013, and is important in the life’s work of Adolf Feszty. The stage by stage analysis of the of the design competition is of considerable importance, as the competition was a turning point in the developing architectural culture in early 1880s Budapest. Feszty’s role in the competitions’ history is discussed in this article. Architects’ reaction to the building’s emphasized urban situation became the competition’s key issue. Feszty’s solution to this was a monumental cupola on the corner, which was damaged during World War 2 and later pulled down. The absence of the cupola radically decreases the building’s architectural values. The present form of the palace is lacking; its effect on the urban landscape is much less impressive.
Promise of a New Golden Age − Newly Modern Architecture in Hungary
Authors: Simon Mariann , Laczó Dániel
Published: June 2015

Reinvention and reinterpretation of the Modern Movement emerged in the middle of the 1990s. It was represented in buildings recalling the classical details of modernism and was distributed in the architectural media as well as by theoretical forums. The newly modern trend returned to pre-war modern architecture, which promised a new golden age of modernism by rejecting the compromised modernism of the socialist period, as a media tempestas. The newly modern managed to solve the identity crisis of modernism: the local tradition of Buda eventually legitimated modernist architecture throughout Hungary. However, among the restrictions on historical and stylistic issues, technology and modernization could not make way for a progressive architecture. The newly modern served mainly one class, the re-emerging Hungarian bourgeoisie. The economic crisis eventually marginalized the whole newly modern movement.
Perceptions of dental undergraduates in India of a clinical induction program
Authors: Panchbhai Arati
Published: June 2015

This study aimed to investigate undergraduate students’ perceptions of the clinical induction program for dental undergraduates conducted at the DMIMS Deemed University, Sawangi-Meghe, India. Seventy-four third-year dental students who entered the clinical phase of the dental program in 2012 and attended all sessions of the clinical induction program were enrolled in this study. The students’ perceptions of the clinical induction program were assessed through a Likert-scale questionnaire, focus group discussions, and individual interviews. Seventy-two students (97.3%) responded positively about the program, evaluating it as successful and making a few suggestions. Fifty-four students (73.0%) stated that the clinical tours and visits to the departments were the best feature of the program. Nine students (12.2%) suggested that the program should include interaction with their immediate seniors and that interactive activities should be included in the program. The induction program may help students become acclimated during the first few days of being introduced into the clinical phase of their education. It is crucial to ensure that students do not develop a negative attitude towards their educational program by facilitating their smooth transition to the clinical phase.
Sámi time, space, and place
Authors: Hornberger Nancy H. , Outakoski Hanna
Published: June 2015

Late in the evening before a regular school day, the mother of a Sámi family gets a call from her husband working at the reindeer corral saying that the reindeer will be brought in for separation and round-up early in the next morning. In the morning the rest of the family will join the father and other relatives at the reindeer corral and will be working late with the reindeers that day. At school the teachers get the information about the reindeer roundup from those children that are present in the morning, or from Sámi colleagues that have also gone to the corral. That day must, for the most part, be rescheduled at very short notice. The reactions to the changes are varying amongst the staff. The time used for rescheduling and planning the rest of that school day, or the coming couple of days, is not something that any member of the staff is looking forward to, but the attitudes, frustration and values that relate to the unpredictability of everyday life and the peculiarities of this particular cultural context are experienced in many different ways.
Fano Resonance Enhanced Nonreciprocal Absorption and Scattering of Light
Authors: Hopkins Ben , Miroshnichenko Andrey , N. Poddubny Alexander , Kivshar Yuri
Published: June 2015

We reveal that asymmetric plasmonic nanostructures can exhibit significantly different absorption and scattering properties for light that propagates in opposite directions, despite the conservation of total extinction. We analytically demonstrate that this is a consequence of nonorthogonality of eigenmodes of the system. This results in the necessity for modal interference with potential enhancement via Fano resonances. Based on our theory, we propose a stacked nanocross design whose optical response exhibits an abrupt change between absorption and scattering cross-sections for plane waves propagating in opposite directions. This work thereby proposes the use of Fano resonances to employ nanostructures for measuring and distinguishing optical signals coming from opposite directions.
Electrothermally-Actuated Micromirrors with Bimorph Actuators—Bending-Type and Torsion-Type
Authors: Tsai Cheng-Hua , Tsai Chun-Wei , Chang Hsu-Tang , Liu Shih-Hsiang , Tsai Jui-Che
Published: June 2015

Three different electrothermally-actuated MEMS micromirrors with Cr/Au-Si bimorph actuators are proposed. The devices are fabricated with the SOIMUMPs process developed by MEMSCAP, Inc. (Durham, NC, USA). A silicon-on-insulator MEMS process has been employed for the fabrication of these micromirrors. Electrothermal actuation has achieved a large angular movement in the micromirrors. Application of an external electric current 0.04 A to the bending-type, restricted-torsion-type, and free-torsion-type mirrors achieved rotation angles of 1.69°, 3.28°, and 3.64°, respectively.
First-Principles Studies of Hydrogen Adsorption at Pd-SiO2 Interfaces
Authors: Irokawa Yoshihiro , Usami Mamoru
Published: June 2015

The interaction of hydrogen with Pd-SiO2 interfaces has been investigated for the first time using first-principles calculations based on density functional theory. The hydrogen-induced polarization at the Pd-SiO2 interfaces was evaluated using Pd-SiO2 interface supercells. As a result, the potential change induced by interfacial hydrogen atoms was not observed even for hydrogen concentration of ~1.3 × 1015 cm−2 at the Pd-SiO2 interface. This result implies that hydrogen does not create an electric double layer at the Pd-SiO2 interface but change the property of the SiO2 region, resulting in the hydrogen sensitivity of the devices.

Résumé. - Le commerce de Roubaix-Tourcoing souffre de deux lourds handicaps : la dégradation socio-économique locale liée à la crise de l'industrie textile et la concurrence conjointe des grands centres commerciaux périphériques ainsi que de la proximité de la métropole lilloise et du commerce frontalier belge. La disparition nette des points de vente est limitée mais elle masque une forte instabilité du paysage commercial. Beaucoup de nouveaux commerçants sont en fait des chômeurs ou des personnes défavorisées, sans expérience professionnelle, et qui cherchent avant tout à bénéficier de l'aide publique à la création d'entreprise.
L'offensive des hard-discounts en France (Hard discounters in France)
Authors: Anquez Marie-Claude
Published: June 2015

Résumé. - Inconnu en France à la fin des années 1980, le hard-discount a pris une importance croissante. Aujourd'hui, on compte plus de 600 magasins réalisant environ 15 milliards de chiffre d'affaires. Les raisons du succès sont les suivantes : une présentation dépouillée en assortiment limité, un approvisionnement international et des règles rigoureuses de gestion. Avec des prix inférieurs de 20 % ceux des supermarchés traditionnels, ces nouvelles formes de vente peuvent être une solution à la désertification commerciale des secteurs défavorisés.

Abstract. - Soil erosion is an ancient concern for all developers in the mediterranean and tropical realms. The numerous investigations in progress prove that the working methods in the study of the phenomenon must be sharpened, that the most heavy technics in antierosion fight are not necessarily the most efficient, that the foremost and essential move for those who wish to succeed in the field goes through winning the support and cooperation of all rural populations concerned.

Résumé. - Des études détaillées dans le Nord du Maroc conduisent à réviser les approches catastrophistes développées jadis. Les observations qui confrontent parcelles cultivées et zones incultes suggèrent que la mise en culture n'a pas de répercussions aussi spectaculaires qu'on l'affirme, sauf en cas de précipitations particulièrement intenses. Une bonne partie des produits exportés hors des bassins-versants provient de l'érosion agissant dans les chenaux d'écoulement concentré et non des versants.

Droit économique et police des métiers en France du Nord (milieu du XIIIe-début du XVe siècle)
Authors: Desportes Pierre
Published: June 2015

A la fin du XIVe siècle, cinq villes de la France du Nord — Noyen, Péronne, Reims, Béthune et Laon — ont pris l'initiative de faire rassembler des règlements de métier jusque-là épars et demeurés largement coutumiers. Leurs dispositions concernent la plupart des professions, tant alimentaires qu'industrielles, alors représentées dans une ville d'importance moyenne. Rédigés et mis en forme à une époque où les métiers sont encore ouverts, ces codes reflètent la tradition du XIIIe siècle, mais ils apportent surtout des informations précieuses sur les transformations qui sont en train de s'opérer en matière de droit économique.
Le parallèle avec l'Antiquité dans la littérature hollandaise de la Renaissance
Authors: Den Haan Hans
Published: June 2015

This study deals with the parallel with Antiquity, the comparison of people, objects and events found in the Bible and the classical antiquity on the one hand, and contemporary times on the other. The exact function of such a parallel was closely connected to the ideas then prominent on history. In countries such as France or Italy where Renaissance humanists and artists currently believed in the cyclical character of history, one compared the objects and contingencies of classical antiquity to objects and contingencies of contemporary times in order to decide which came nearer the supra-temporal standard of perfection. The use of the parallel could not allow to provide a definite evidence of the universal worth of the compared object. But this possibility existed in the Dutch Renaissance which believed in a linear conception of history. An accurate comparison with Antiquity meant a praise or, in case of a controversial object, a justification.
L'enseignement de la langue polonaise dans les écoles primaires en France
Authors: Gogolewski Edmond
Published: June 2015

L'enseignement de la langue polonaire dans les écoles primaires en France s'est pleinement développé dans la période de l'entre-deux-guerres. Les démarches pour officialiser cet enseignement n'aboutirent qu'en 1924, alors que les écoles privées, généralement subventionnées par les compagnies minières, lui avaient déjà accordé une place dans leur emploi du temps, comprenant la nécessité de donner aux 60 000 petits Polonais, appelés à retourner plus tard en Pologne, la possibilité d'apprendre leur langue maternelle. Après la guerre, la reconnaissance de la République populaire de Pologne, la nationalisation des mines et l'établissement définitif en France des immigrés polonais en tramèrent une scission dans le corps enseignant polonais partagé entre le gouvernement provisoire de Londres et le gouvernement communiste de Varsovie.

Een studie over de grenzen van de gebieden van de Rémi en de Treviri in het oosten van het département van de Ardennen. Men treft vijf voorname orientaties aan, vaak in verband met de twee gebieden, die men echter ook in andere streken aantreft. De eenheid van 710 meter vindt men in een aantal maten terug. Men kan zelfs volledige centurias isoleren. Men vindt de cadastratieassen weer op wegen en op gemeentegrenzen. Zij hebben ook de orientatie van kerken en begraafplaatsen bepaald. Twee villa's hebben dezelfde orientatie (21° NW) als het cadaster waarin zij liggen. Twee complémentaire cadastrs steunen op drie belangrijke hoogten van de streek. Tenslotte zijn er nog drie systemen die in direct verband staan met de grote weg van Reims naar Trier.

A Relevant Data Revolution for Development
Authors:   RTI International, Crouch Luis
Published: June 2015

The paper argues that generalizing from standard tenets of big data to developing country situations should be done only with considerable caution. The emerging term of art for a careful application of big data tenets to public policy issues in developing countries is “data revolution for development.” Yet what this might consist of is not well-defined in the literature. The paper proposes four areas of work that could be a practical approach to a data revolution for development: (1) improving legacy systems and “little data,” including adding citizen-sourced information; (2) improving integration, classification, and curation of existing and new data; (3) adding value to data through predictive analytics and citizen empowerment; and (4) demonstrating use of data in managing service delivery in developing countries.
Two new species of Scymnini (Coleoptera: Coccinellidae) from Karnataka, India
Authors: Poorani J.
Published: June 2015

The Scymnini (Coleoptera: Coccinellidae) of the Indian region is rich and highly speciose, with nearly 90 described species and scores of undescribed species (Poorani 2002). There is a dire need to systematically revise the genera and species of this tribe from the Indian region. Due to paucity of representative collections covering the entire region and lack of access to types, it is difficult to identify most of the Scymnini of the Indian region to species. As a result, many economically important species remain poorly characterized, or worse, unnamed.

Two economically important and unique species of Scymnini (Coccinellidae) belonging to Horniolus Weise (1900) and Scymnus (Pullus) Mulsant (1846) from the Southern Indian state of Karnataka that have remained unnamed for long are treated in this paper. These species are externally similar to other known species and often misidentified. Horniolus sororius sp. n. and Scymnus (Pullus) rajeshwariae sp. n. (Coleoptera: Coccinellidae) are described here and illustrated with notes on their biology and related species.
Severe Symptomatic Aortic Stenosis in Older Adults: Pathophysiology, Clinical Manifestations, Treatment Guidelines, and Transcatheter Aortic Valve Replacement (TAVR)
Authors: Yurek Leo A. , Jakub Karen E. , Menacho Melissa M.
Published: June 2015

The only effective treatment for symptomatic aortic stenosis in the older adult population is surgical aortic valve replacement. However, more than 30% of candidates are denied surgery due to advanced age and multiple comorbidities. Without surgical intervention, death from symptomatic aortic stenosis approximates 2% per month, with mortality rates of approximately 50% within 2 years of symptom onset. There is no effective medical treatment for severe symptomatic aortic stenosis; care has been limited to palliative remedies and end-of-life decisions. Nascent advances in miniaturization and catheter technologies provide a new and less invasive approach: transcatheter aortic valve replacement (TAVR). The current article summarizes treatment guidelines; pathophysiology; clinical manifestations, progression, and classification of severe symptomatic aortic stenosis; and introduces TAVR and discusses randomized controlled trials involving three patient populations from the United States, with relevant nursing implications.

Is Inferior Oblique Overaction Associated With Astigmatism?
Authors: Al-Haddad Christiane , Antonios Rafic , Khatib Lama , Jaroudi Mahmoud , Khawam Edward
Published: June 2015

Purpose:

To study the relationship between inferior oblique muscle overaction and astigmatism, and to explore any change in astigmatism after surgery.

Methods:

This was a retrospective chart review of patients undergoing strabismus surgery. Demographic data collected included age, diagnosis, preoperative refraction, presence of inferior oblique overaction, surgery performed, and postoperative refraction. Patients were divided into three groups: those having only horizontal strabismus without inferior oblique overaction (no inferior oblique group) as a control group, those having bilateral inferior oblique overaction (bilateral inferior oblique group), and those having unilateral inferior oblique overaction (unilateral inferior oblique group). Right eyes of the bilateral inferior oblique and no inferior oblique groups were chosen for analysis, whereas the eye with inferior oblique overaction was included in the unilateral cases. Refractions were converted to power vector coordinates for comparison. Statistical analysis was performed to compare the power vectors among groups using the no inferior oblique group as controls and to explore any postoperative change in astigmatism.

Results:

One hundred eighteen patients undergoing strabismus surgery were included (60 males and 58 females; mean age: 11.31 ± 10.59 years). Patients were divided into three groups: those having only horizontal strabismus without inferior oblique overaction (no inferior oblique group; 60 patients) as controls, those having bilateral inferior oblique overaction (bilateral inferior oblique group; 41 patients), and those having unilateral inferior oblique overaction (unilateral inferior oblique group; 17 patients). Preoperatively, there were no differences in astigmatism when comparing eyes with and without inferior oblique overaction. Postoperatively, both the no inferior oblique group and the bilateral inferior oblique group equally showed an increase in with-the-rule cylinder power (
P
= .02 and .01, respectively).

Conclusions:

Inferior oblique muscle overaction did not result in an increased prevalence of astigmatism along the axis of the overacting muscle.

A NUMERICAL STUDY ON THE HEMODYNAMIC AND SHEAR STRESS OF DOUBLE ANEURYSM THROUGH S-SHAPED VESSEL
Authors: Halabian Mahdi , Karimi Alireza , Beigzadeh Borhan , Navidbakhsh Mahdi
Published: June 2015

Abdominal aortic aneurysm (AAA) is a degenerative disease defined as the abnormal ballooning of the abdominal aorta (AA) wall which is usually caused by atherosclerosis. The aneurysm grows larger and eventually ruptures if it is not diagnosed and treated. Aneurysms occur mostly in the aorta, the main artery of the chest and abdomen. The aorta carries blood flow from the heart to all parts of the body, including the vital organs, the legs, and feet. The objective of the present study is to investigate the combined effects of aneurysm and curvature on flow characteristics in S-shaped bends with sweep angle of 90° at Reynolds number of 900. The fluid mechanics of blood flow in a curved artery with abnormal aortic is studied through a mathematical analysis and employing Cosmos flow simulation. Blood is modeled as an incompressible non-Newtonian fluid and the flow is assumed to be steady and laminar. Hemodynamic characteristics are analyzed. Grid independence is tested on three successively refined meshes. It is observed that the abrupt expansion induced by AAA results in an immensely disturbed regime. The results may have implications not only for understanding the mechanical behavior of the blood flow inside an aneurysm artery but also for investigating the mechanical behavior of the blood flow in different arterial diseases, such as atherosclerosis.

Authors: Ionescu Adriana
Published: June 2015

This paper presents analytical, numerical and experimental studies of SERB TEL-150 new Romanian devices for dissipation of seismic energy for buildings affected by Romanian Vrancea earthquakes. These devices were invented to be positioned at the foundation of buildings and were tested in static cases. The purpose of these studies is to determine the analytical model of the special shape hysteresis of these new devices which is necessary to obtain the mathematical equation for these hysteresis curves. The experimental and the numerical analysis of SERB TEL-150 were performed in order to determine the experimental and the numerical hysteresis curves which are to be modeled with a modified Bouc-Wen model. These devices were invented by PhD.eng. Viorel Serban (CITON – Center for Technology and Engineering for Nuclear Projects) and they were used for equipping NAVROM building in Galati, Romania.
Computational Studies for Comparison between BRB Dampers and SERB New Romanian Dampers Performance in Damping System of High Buildings
Authors: Ionescu Adriana
Published: June 2015

This paper presents a computational study for comparison of the behavior of a ten stories building equipped with two type of damping system: Buckling Restrained Braces (BRB dampers) and SERB new romanian dampers, during romanian earthquakes, according to romanian codes for seismic analysis. This study was computationally finalized using a software program made by the authors which permits time-history dynamic analysis of buildings equipped with different damping devices with different hysteresis such as: Maxwell, Kelvin-Voigt, Zener, Bouc-Wen, Taylor. The study will compare the drifts and the forces applied to the structure by the dampers. The SERB C-194 dampers are a cheaper way to protect the building during earthquake and restrict the drifts similarly with BRB dampers.

Published: June 2015

Natural fibers have recently become attractive to automotive industry as an alternative reinforcement for glass fiber reinforced thermoplastics. The best way to increase the fuel efficiency without sacrificing safety is to employ fiber reinforced composite materials in the body of the cars so that weight reduction can be achieved. The latest thermo plastic developments have resulted in higher material properties and more possibilities in the design of bumper beams. However the use of steel, aluminum, glass thermoplastics, sheet metal components, bumpers becomes at higher cost than long fiber reinforced thermoplastics.

This paper presents the results obtained by the authors when applying mechanical test methods that are validated using fatigue testing under simulated regime with finite element analysis. In addition to the mostly mandatory physical tests, the simulated regime testing can validate emerging conclusions. Virtual testing conclusions (computer simulated via Cosmos finite element analysis software), strengthen, complement and increase the accuracy of physical test conclusions. During the investigation of the physical test results, there are cases where the simulated physical test is not always explainable. This paper presents a case study conducted on special constructed screws that are subjected to fatigue and verified using the finite element analysis. It presents the possibility for practical application of simulated tests in order to redesign structures that fail during physical tests.

Published: June 2015

Area flooding is the main parameter necessary to achieve hydro technical defense schemes. This can be determined based on calculations performed in various programs. Of the many measures to limit the risk of flooding were chosen for comparison hydrotechnical for protection against floods schemes: embankment and building a polder area. Finally it is noted that structural measures are widely promoted because of the benefits arising from economically and ecologically necessary but complementary structural measures are the only high efficiency in cases with high abundant torrential floods. Today hydro technical schemes are a techno-economic and environmental compromise with fluctuating boundaries, making the decision to be very heavy, plus taking into consideration the temporal variability and the aspect of economy and nature. The optimal solution is specific to each river basin and establishing its methods are different, many of which are listed in this paper.

Motto: “We cannot prevent disasters ... What we hope to do is to be more proactive, to be better prepared so that we can react better, faster.” Winston Choo, 2006The exigencies of environmental protection must be concomitantly achieved both at micro and macroeconomic levels, at individual and national states and international communities’ levels. No matter the scale we refer to, there should be taken strict actions meant to modify the present tendencies of environmental deterioration in order to permanently maintain an equitable balance between satisfying the more and more diverse necessities of present society and protecting all components of environment. Although it is difficult or, in some cases, even impossible to establish their appearance within time and space coordinates, the majority associates them with the period of industrial revolution, because the man’s wish of a better, more sustainable life has uncontrollable effects on the environment, or the climate. Thus, the change with its multiple faces and components remains a priority for the protection of the environment and of the sustainable development, and people face the most important choice of their long history.One with paradigmatic values – having rational, ecologic, protectionist, emotional, educational valences – generated by the troubling metamorphoses like: the exhaustion of natural resources, “baby-boom” beyond any control, the ecologic unbalances, the inequality of chances when education, health and carrier are concerned.

Published: June 2015

In our study we describe the navigation training requirements for simulator training, and analysing the suggested infrastructure of an inland navigation simulator training centre. Intensity of navigation training on the Inland Navigation Simulator depends on its character and the chosen difficulty (complexity). The participant of the navigation training has to be able to carry out the minimum training skills depending on the difficulty. The level of difficulty could be divided according to the education target like: basic trainings for non-professionals, medium level trainings for crew on operational level, high level training for crew on management level (+ practicing Local Knowledge Requirements (LKR) if possible).

Published: June 2015

The use of additive manufacturing (AM) systems in scale production has rapidly increased in recent years. The growing tendency to adopt AM technologies into established manufacturing systems has led to research that considers the optimisation of both process and resource planning. In order to maximise the outputs of such a production process, planning must be conducted rigorously. This paper proposes an automated software tool, called EasyPlan, which streamlines the optimisation of resource planning. The algorithm is developed using LabVIEW and is demonstrated for an AM component from the medical industry. For the evaluation process, parameters such as stock levels, delivery terms and technical charts of the products are provided. A user friendly interface is developed, making EasyPlan versatile to all types of environments.

Published: June 2015

In our study we concern with the quantification of the weighted average cost of capital, as the minimization criterion for the company capital structure optimization. To achieve more accurate estimation of the costs of capital we calculated them using four models with weights assigned on the basis of their explanatory power of the particular company. In the next step, the possibility of application of individual models and their explanatory power in the countries with poorly developed capital markets, where the necessary data for the calculations absent and there is the impact of the financial crisis, is determined. Our aim in further research is to design company liability management methodology which contains other optimization criteria.
New Concept of Quality Management in Shipbuilding
Authors: Savu Ionel Danut , Savu Sorin Vasile , Ghiba Mihai Gheorghe
Published: June 2015

Fabrication in shipbuilding faces important requirements from the quality point of view, due to potential risks specific to the exploitation of the naval structures. Quality Management becomes important tool to reduce the susceptibility to failure of different components of the structures. Specific processes are involved in shipbuilding and the Quality Management should address all of them. Inspection Test Plan (ITP) should be the first step of the Quality Management and that step is previous to any action related to fabrication. Sometimes, that step is necessary to be done even before the design of the naval structure. The most important processes which are required to answer to the ITP are welding, testing of welds, treating distortions and painting. For each of them, qualification of personnel, qualification of the involved procedures, qualifications of the materials and consumables should be evaluated. Operational procedures for every step of the fabrication and for auxiliary operations should be elaborated, discussed and approved by the Quality Manager.

Published: June 2015

Using powder metallurgy techniques new porous materials for self-lubricating bearings were developed. These materials are characterized by total porosity, which represents their major advantage for tribological applications, acting like their own oil reservoir. Sometimes the presence of pores can be also detrimental to the part performance. Among the causes of the bearings failure is their increased porosity for improving the lubricant retention capacity. Consequently, this can lead to a significant loss in strength. In the present work tensile test specimens based on Fe-Cu/brass-Sn-Pb powders were prepared in order to investigate the morphology of the fracture surfaces and to analyze the effect of pores on the failure process of these materials subjected to tensile loads. Distinct morphologies of the pores area were revealed by SEM images of the fracture surfaces.

Amorphous Fe75Si20-xB5Mxpowders with M= Ti, Ta or Zr andx= 0 and 5 were synthesized by wet mechanical alloying, using benzene as a surfactant. The thermal stability of the Fe-Si-B alloy increases by introducing transition metals. The replacement of 5% Si with Ti, Ta or Zr leads to an increase of the crystallization temperature. It was found that the replacement of 5% Si with Zr increases the crystallization temperature with 115 °C, and also reveals a glass transition temperature around 580 °C.
