Authors: Skačkauskienė Ilona , Katinienė Aušra
Published: June 2015

As the information society is gradually transforming into the knowledge society, it is affecting not only consumer preferences and needs but also the changes in corporate activities. Both corporate performance and potential depend on the ability to evaluate, manage and develop available knowledge. Systematic and purposeful application of knowledge gives advantage to companies, whereas personnel knowledge, ideas and skills serve as an impetus of a successful organisation. The article offers a critical view of the concept of knowledge used by researchers and introduces a new definition, employs a new concept of knowledge potential that combines the knowledge of all types and is based on various analysed knowledge types, and assesses the concept of networking and its importance to knowledge potential. Vykstant transformacijai iš informacinės į žinių visuomenę keičiasi vartotojų prioritetai ir poreikiai, lemiantys ir organizacijų veiklos pokyčius. Organizacijos veiklos rezultatai, potencialas priklauso nuo gebėjimo įvertinti, valdyti ir plėtoti turimas žinias. Sistemingai ir tikslingai naudojamos žinios suteikia pranašumo organizacijai, o darbuotojų žinios, idėjos ir įgūdžiai yra sėkmingos organizacijos varomoji jėga. Siekiant išanalizuoti žinių potencialo formavimąsi tinklaveikos visuomenėje, taikyti mokslinės literatūros loginės analizės, abstrakcijos, sintezės metodai. Tikslui pasiekti iškelti šie uždaviniai: apžvelgti žinių tipus ir sampratą, kritiškai įvertinti ir apibrėžti žinių, žinių potencialo, tinklų ir tinklaveikos sąvokas, būtinas tolimesniems šios srities tyrimams.

ANALYSIS OF METHODOLOGICAL POTENTIAL FOR EVALUATION OF CORPORATE SUSTAINABLE DEVELOPMENT / ĮMONIŲ DARNIOS PLĖTROS VERTINIMO METODINIO POTENCIALO ANALIZĖ
Authors: Oželienė Danguolė , Drejeris Rolandas
Published: June 2015

In the XXth century the concept of public welfare was associated with economic growth and its rate. It was assumed that the economic growth provides society with the needed tools to solve its ecological and social problems. Theory attempted to explain the most important factors influencing economic growth and its efficient management. Yet it was discovered that the market economy system is not capable of solving society’s problems. The new type of world society and economy requires the rapid formation of processes, which reflect changing consciousness of the population. These processes include the rapid development of information technology, globalisation, which highlighted the significance of the environment, and the formation of social movements. Moreover, all the issues arising due to rapid changes can be rationally solved in a sustainable way. The analysis of methods used for evaluation of sustainable development has demonstrated that there is a lack of studies devoted to the assessment of sustainable development at the enterprise level. The most common problem encountered while assessing sustainability of the enterprise at the national and regional levels are the inadequate indicators. These should be based not only on the economic, environmental and social dimensions but as well on the technological and institutional dimensions. Another problem is the unreasonable number of the chosen indicators, which do not represent its distinct significance. This paper analyzed the problems of the concept of sustainable development and its implementation at different levels because the progress can only be made when there are challenges to overcome. The concept of sustainable enterprise was analyzed, followed by a discussion of importance of assessment of sustainability in the enterprises with its positive and negative aspects. Guidelines for future research were also established. Darnios plėtros vertinimo metodų analizė mokslo darbuose parodė, kad pasigendama tyrimų, skirtų darnios plėtros vertinimui įmonių lygmenyje.

Law of the Nations, law for the Nations : The Early Development of Measures for International Human Rights in the Hebrew Bible
Authors: Achenbach Reinhard
Published: June 2015

Lors de la période perse, la compréhension qu’Israël a de son Dieu évolue : les auteurs sacerdotaux définissent Yhwh comme unique Dieu de l’univers. Une telle définition a des implications éthiques comme le montre par exemple la loi de Gn 9,5b-6. Cette élaboration d’une éthique universaliste par la littérature juive de l’époque perse connaît des parallèles dans la littérature hellénistique. La littérature prophétique d’Israël développe également, à l’époque perse, la notion de « responsabilité morale universelle d’Israël » face aux nations, comme l’attestent les chants du serviteur d’Isaïe (cf. Is 42,1-3 ; 49,6).
Le culte comme élément déterminant de l’identité d’Israël dans le Code de l’Alliance
Authors: Dufour Bertrand
Published: June 2015

Une étude d’Ex 20,22-26 prenant en compte les textes parallèles et le contexte littéraire permet de penser que ces versets auraient été ajoutés tardivement, à l’époque perse, au Code de l’Alliance dont ils deviennent la nouvelle introduction. Bâtie à partir de divers matériaux ou traditions, cette péricope peut avoir pour fonction d’insérer le Code de l’Alliance dans l’ensemble Ex 19-24 et d’unifier la collection législative qui suit en ordonnant au service de Yahvé des prescriptions très variées. Au plan théologique, face à Dt 12,11 qui requiert un lieu unique choisi par Yahvé, y a-t-il en Ex 20,22-26 légitimation de plusieurs lieux de culte dans le cadre du judaïsme multicentrique de l’époque perse ou une volonté d’archaïser pour souligner l’évolution subséquente de Dt 12 ?
Quelle identité de Dieu en Ex 3,1-6 ?
Authors: Lepesqueux Guillaume
Published: June 2015

L’objectif de la présente communication est de montrer qu’Ex 3,1-6 est un texte-carrefour à travers lequel sont non seulement récapitulées, mais également anticipées plusieurs affirmations fondamentales concernant les identités de Dieu et de Moïse, étant entendu que l’un ne fonctionne pas sans l’autre. Une attention particulière est pour cela accordée à la structure du texte, aux éléments d’intertextualité et aux questions que soulève la multiplication des détails dans le v.1.
Femmes dans une ecclésiologie intégrale
Authors: Pelletier Anne-Marie
Published: June 2015

La constitution Lumen Gentium du concile Vatican II envisage, entre le sacerdoce commun des fidèles et le sacerdoce ministériel, une différence d’essence, et non seulement de degré (LG 10), et offre ainsi une possibilité de penser de manière renouvelée la place des femmes dans la vie de l’Église, non pas seulement en fonction des responsabilités qu’elles pourraient y exercer, mais avant tout, en fonction d’une compréhension renouvelée de son mystère. En effet, la formulation de Lumen Gentium permet de dépasser une vision simplement hiérarchique de la relation entre sacerdoce commun et sacerdoce ministériel. Si le sacerdoce ministériel renvoie l’Église au sacerdoce du Christ dont elle procède, il se trouve lui-même placé, à ce titre, au service du sacerdoce commun – ou « existentiel » – des fidèles. La notion de sacerdoce des fidèles constitue ainsi une clef de compréhension de la mission de tous les baptisés – femmes et hommes : à l’exemple du Christ, leur mission primordiale consiste à servir l’autre, dans la réalité incarnée du quotidien.
Instructions to Patients and Families Following Strabismus Surgery
Authors: Dotan Gad , Qureshi Hanya M. , Nelson Leonard B.
Published: June 2015

Purpose:

To analyze postoperative instructions provided to patients and families after strabismus surgery.

Methods:

In April 2012, a 12-question electronic survey was sent to all members of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) regarding their instructions to patients undergoing strabismus surgery. The questions specifically addressed patients’ daily activities, such as their resumption of school and work, sports, swimming, normal showering and bathing, and contact lens use.

Results:

One hundred two responses were completed; 96% were from pediatric ophthalmologists regularly performing strabismus surgery. Participation was greater by North American members (86%) and respondents with more than 10 years of experience (75%). Fifty percent of the respondents advised patients to resume normal showering and bathing 24 hours after surgery. Conversely, respondents recommended that children wait 3 to 4 days before resuming schoolwork (52%) and at least 2 weeks before playing in a sandbox (47%). Furthermore, respondents indicated that patients should refrain from participating in sports-related activities for at least 1 week (43%) and should not go swimming for at least 2 weeks (56%). Finally, 47% advised their patients not to wear contact lenses for 2 weeks after surgery.

Conclusions:

Overall, the responses indicated a high regard among AAPOS members for promoting normal healing and prevention of infection and other postoperative complications; however, certain trends, such as the recommendation regarding normal showering, may intimate a lack of further infection prevention.

Clinical Insights Into Foveal Morphology in Albinism
Authors: McCafferty Brandon K. , Wilk Melissa A. , McAllister John T. , Stepien Kimberly E. , Dubis Adam M. , Brilliant Murray H. , Anderson Jennifer L. , Carroll Joseph , Summers C. Gail
Published: June 2015

Purpose:

A hallmark of albinism is foveal hypoplasia. However, literature suggests variable foveal development. This study evaluates the association between ocular phenotype and foveal morphology to demonstrate the broad structural and functional spectrum.

Methods:

Best-corrected visual acuity (BCVA), nystagmus, angle kappa, stereoacuity, iris transillumination, macular melanin presence, foveal avascular zone, and annular reflex were recorded in 14 patients with albinism. Spectral-domain optical coherence tomography provided macular images.

Results:

The clinical phenotype was broad, with BCVA varying from 20/20 to 20/100. Better BCVA was associated with a preserved foveal avascular zone, annular macular reflex, stereoacuity, and macular melanin. Imaging demonstrated a continuum of foveal development correlating with BCVA. Individuals with a rudimentary pit had normal inner and outer segment lengthening and better BCVA.

Conclusions:

The spectrum of ocular structure and visual function in albinism is broad, suggesting a possible diagnosis of albinism in a patient with an even more normal clinical presentation.

The complex early life history of a marine estuarine-opportunist fish species, Solea turbynei (Soleidae) from temperate South Africa
Authors: Strydom Nadine A. , Coetzer Crystal J. , Pattrick Paula
Published: June 2015

The early life history stages and ecology of Solea turbynei, a marine estuarine-opportunist species, is described from nursery areas in Algoa Bay, South Africa. Early life history stages were collected over multiple years from known nursery habitats using plankton, fyke and larval seine nets. The larvae are described using morphometric measurements, meristic counts and pigmentation based on 29 individuals. Solea turbynei is differentiated from other Soleidae by the small size at flexion (3-4 mm), low myomere count and presence of two characteristic blotches of pigment on the dorsal fin. This species has a unique early life history strategy in that the larvae progressively span nearshore, surf zone and estuarine habitats with ontogeny. Abundance of preflexion stages peaks in summer in nearshore waters, indicative of peak spawning period but preflexion larvae are present throughout the year, indicating protracted spawning by adults. At flexion stage, larvae utilize surf zones where metamorphosis and settlement takes place. Early juveniles migrate into the sandy lower reaches of estuaries, after which fish take up residency to adulthood. Warm water is important for larval growth and survival in the nearshore, while turbidity shows a positive relationship with recruitment into estuarine nurseries.
Population structure of the pearly razorfish, Xyrichtys novacula (Actinopterygii: Labridae), in sand-seagrass mosaics: spatial variation according to habitat features and sampling techniques
Authors: Espino Fernando , Triay-Portella Raül , González José Antonio , Haroun Ricardo , Tuya Fernando
Published: June 2015

Habitat structure affects the distribution of fishes, particularly across reef-dominated habitats, but few studies have connected patterns in the abundance of soft-bottom fishes with the structure of the habitat. The spatial and temporal patterns of variation in the abundance, biomass and population structure of the pearly razorfish, Xyrichtys novacula, inhabiting sand-Cymodocea nodosa seagrass mosaics were described through two complementary techniques: underwater visual counts and seine nets. We sought to analyse whether biotic (seagrass shoot density, leaf length and meadow cover) and abiotic (sediment composition and particle size) structural elements explained variation in patterns of abundance and biomass. Underwater visual counts registered a larger abundance of individuals and proved significant variation in fish abundance and biomass at the scale of locations, which was otherwise not detected through seine nets. Seasonal variation in fish abundance and biomass was, in all cases, minor. Habitat structural elements helped to explain patterns in fish abundance and biomass. This fish species was particularly abundant in sediments dominated by coarse sands in continuous meadows of C. nodosa ( > 90% seagrass cover) with intermediate densities of 500 to 1000 shoots m–2, followed by large-sized seagrass patches with >1000 shoots m–2. A trade-off between protection provided by seagrass canopies and protection derived from its burial behaviour, limited under high seagrass shoot densities, may explain spatial variation patterns.
Discount Factor for Durable Goods
Authors: Bajo-Buenestado Raul
Published: June 2015

Incentives for car purchase have been a common concern for politicians in Spain. In this paper, the author wants to focus on two recent policies: Plan VIVE and Plan 2000e, introduced in 2008 and 2009 respectively. The data on car sales in Spain show that after the introduction of the Plan 2000e there was a significant increase in the number of vehicles sold in Spain. But that seems quite contradictory with the features of these plans: if one assumes an average consumer, who borrows money at a certain interest and that repays it in several years, it can be seen that actually it is possible to save more money using the Plan VIVE rather than the Plan 2000e. Provided is evidence to support that the key to understand this puzzle is time preference: car purchase, as many other durable goods, has a very strong intertemporal discount factor. The hypothesis is demonstrated by the fact that, at least in Spain, people prefer an initial lump-sum payment in order to purchase a car rather than a financial program with better conditions.
Online Social Gambling and Its Implications for the Study of Marketing Communications
Authors: Ozuem Wilson , Prasad Jason
Published: June 2015

Gambling has been a part of humanity for a long time, and references to it have been found in some of the earliest dated records. Literature on the topic has been accumulating since ancient times. The advent of Internet technology along with its typical subsets provides a new approach to how gambling is conducted in postmodern times. Drawing on qualitative research and utilising a single case study strategy, this study examines online social gambling and real money gambling marketing communication practices as well as offers some insights into the development and implementation of effective marketing communication programmes. In contrast to existing studies, the paper, in part, proposes integrative and higher levels of marketing communication programmes between online social gambling and real money gambling environments.

Published: June 2015

The design of gears is critical for smooth running of any mechanism, automobile and machinery. Gear drive design starts with the need of optimizing the gear thickness, module, number of teeth etc., this creates huge challenges to a designer. Optimization algorithms are more flexible and gaining importance in engineering design problems, because of the accessibility and affordability of today’s mechanical field. A population based heuristic algorithm offers well-organized ways of creating and comparing a novel design solution in order to complete an optimal design. In this paper, a new artificial immune system based algorithm proposed as Modified Artificial Immune System (MAIS) algorithm is used to optimize a gear design problem. The results are compared with an existing design.

Authors: Suresh P. , S Ramabalan , Natarajan U.
Published: June 2015

In order to render cost effective and environmentally friendly products, sustainability is gaining importance in contemporary manufacturing organizations. The rapidly changing marketplace also means that organizations are in search of integrated approaches for creating sustainable product. In this context, this paper reports a case study carried out in an automotive component of single cylinder four stroke petrol engines. The candidate product is connecting rod. The existing handle of connecting rod has been modeled using computer-aided design (CAD). Then, the sustainability analysis has been carried out on the existing component for determining the environmental impact. This is followed by the engineering analysis of the component using computer aided engineering (CAE). Then the redesign of the handle performed by using design for manufacture and assembly (DFMA) principles. The sustainability factors have been measured in terms of carbon footprint, air acidification, energy consumption, and water impacts. It has been found that the redesigned product possesses minimal environmental impact. It could be knew from the results of the case study that the implementation of DFE (design for environment) and DFMA concept could initiate new developments in sustainable product design with minimal impact on the environment. This integrated approach is considered to be valuable for its implementation in similar product development situations to achieve business benefits such as reduced cost and time which would in turn improve the profitability.

Three Dimensional Simulation of Air Bleed Duct under Deep Drawing of Ti 6Al-6V-2SN
Authors: Gunasekar P.
Published: June 2015

Deep drawing is the compression-tension forming process which has been around for a long time. This is a cheap and cost effective process. This paper investigates the manufacturing of the air bleed duct under deep drawing with the velocity of 7 inches/second. Bleed air is compressed air taken from aircraft turbine engines for cabin climate control and systems such as de-icing equipment and also used in after burners. Bleed air duct used to operate the control of air flow to the cabin and powerplant. Bleed air possesses high temperature and high pressure, hence the quality of the duct should be strong enough to withstand them. In general air bleed duct made of titanium alloys under forming process with low strength, which causes the failure and replacement of air bleed duct when they expose to extreme temperature cases. The deep forming process will increase the strength of the bleed duct which reduces the replacement of air duct periodically and reduces the maintenance cost of the aircraft. In addition this paper provides the stress and strain energy data in order to understand the mechanical behavior of titanium alloy when they undergo high pressure blank process.

Authors: Karthigairajan M. , Mohanamurugan S. , Umanath K.
Published: June 2015

An experiment sturdy has been carried out for jet impingement cooling on the spherically convex surface is the development of mechanism. The effect of curvature, Space between jet exit and target surface, and Reynolds number on heat transfer is investigated for around air jet on hemispherical surface. The flow at the jet exit has fully developed velocity profile. A uniform heat flux boundary is created on the heated surface. The experiments are performed for 5000<Re<25000, 2<L/d<10, and jet diameters ranging from 1.3, 2.1, 3.4, 4.0 and 5.2 cm. In the mean time effect of curvature on local heat transfer is negligible at the wall jet region corresponding to r/d>0.5. From the experimental results the variation of the D/d ratio with local Nusselt number (Nust) for various Reynolds numbers and various L/d ratios are plotted. The results show that Nust increase with increase in curvature and the effect of the curvature will high at high Reynolds number. i.e. Nust at Re=25000 is 25% higher than at Re= 5000 This may be attributed to an increase in curvature increases acceleration, & size of three dimensional counter rotating vortices at stagnation point and the increment of Reynolds number increases the jet momentum, and also enhances the vortices creation. Nust is peaking in the L/d ratio of 6 because of high turbulence intensity as this distance.

Polymers reinforced with synthetic fibers such as glass and carbon offer advantages of high stiffness and strength to weight ratio compared to conventional materials. Despite these advantages, the prevalent use of synthetic fiber-reinforced polymer composite has a tendency to demur because of high initial cost and most importantly their adverse environmental impact. On the contrary, the increased interest in using natural fibers as reinforcement in plastics to substitute conventional synthetic fibers in automobile applications has become one of the main concerns to study the potential of using natural fibers as reinforcement for polymers. In this regard, an investigative study has been carried out to make potential utilization of natural fibers such as Jute and Coir as reinforcements, which are cheap and abundantly available in India. The objective of the present research work is to study the effects of fiber loading and particle size; fiber loading and fiber length on the mechanical properties of Jute-PP and Coir-PP bio-composites respectively. The experiments were planned as per full factorial design (FFD) and response surface methodology (RSM) based second order mathematical models of mechanical properties have been developed. Analysis of variance (ANOVA) has been employed to check the adequacy of the developed models. From the parametric analysis, it is revealed that Jute-PP bio-composites exhibit better mechanical properties when compared to Coir-PP bio-composites.

The structural components made from the composite materials possess outstanding advantages like reliable mechanical properties, durability, and good corrosion resistance, and low density. They also exhibit high impact resistance and good damage tolerance. These merits of composite structures draw the attention of scientists, engineers and researchers in generally the stability of composite structures is verified by carrying out buckling analysis. The aircraft components are made up of laminated composite plates are subjected to buckling analysis, in order to confirm whether the component withstand the critical in plane loads. Composite structural plates provided with circular cut out, square cut out and rectangular cut-out are widely used as structural members in aircraft and vehicle design. The different holes are provided in these members can be access holes, pass-through holes for any hardware or holes for windows and doors. Sometimes these holes are produced for weight reduction in the composite structural components. In this present study, buckling experiments were carried out on Epoxy/woven glass fiber laminated composite plate specimens and the influence of different cut-out shapes like circular, square and rectangle are examined and determined experimentally. Boundary conditions free and clamped were considered for all the experiments. After the buckling experiments, comparisons were made between these two test results. These results show the effect of various cut-out shapes on the buckling load.

In the present study, enhancement of abrasion resistance of phenol formaldehyde (PF) resin based hybrid friction composites with different ingredients viz. binder, micron sized fibers and fillers have been synergistically investigated. Hybrid friction composites based on basalt and recycled aramid fibers were prepared using compression moulding. Three-body abrasive wear tests were conducted according to ASTM G-65 standard by dry sand/rubber wheel abrasion tester using two different size of angular silica sand abrasives (212 and 425 μm) at a constant load of 40 N. The results indicated that the wear volume loss increases with increasing abrading distance and abrasive particle size. However, the specific wear rate decreased with increasing abrading distance and increases with increase in abrasive particle size. Addition of fiber content has a significant influence on the abrasive wear performance of these composites. Further, the worn surfaces were examined by scanning electron microscopy to identify the involved wear mechanisms.

Constructions of pressure vessels like rocket launch vehicles, missiles, rocket propellant tanks, and filament wound pipes for civil and military applications are made out of high strength, high stiffness and light weight composites filaments. Filament winding techniques are used for fabrication of such cylinders and pipes. Many materials like glass fibers, carbon fibers and Kevlar fibers are used due to their good strength when it is subjected to internal pressure as well as external pressure. Basalt fibers are new materials that are fabricated from hard dense basalt rocks. Basalt fibers can be used in the place glass fibers due to their good mechanical behavior when subjected to internal pressure. Plates and beams generally resists bending loads and pipes and tube structures resists internal forces developed through internal and external pressure. This work concentrates the fabrication of filament wound pipes using filament wound techniques and the burst pressure test is carried out. In fuel tanks of rockets, If any one of the layer fails due to internal pressure, there will be mild leakage. For this reason it is mandatory to find out the ply by ply failure. The first ply failure of basalt filament wound pipes subjected to internal pressure is calculated using Finite element analysis. Then the stress and progressive failure analysis was carried out. Maximum stress failure criterion is used for the finite element analysis.
