Authors: Rahman Md Zillur , Akbar Md Ali , Hossain Md Abul , Ali Md Yousuf
Published: November 2015

An experiment with 25 growing goats (in 5 groups) were fed four different tree forage based diets (B,C,D,E) and control A showed that there were significant (p<0.05) differences in DM , ME and DCP intakes. Although there were no significant differences in the digestibility of DM, OM, CP and ADF but intake of these nutrients were significantly (p<0.05) differed among the treatments. There were no significant differences in the digestibility of diets having different forages but they were significantly higher than that of grass based control diet. Feeding of tree forages had significant (p<0.05) effect on live weight gain of goats. Animals fed tree forage based diets significantly (p<0.05) increased weight gain (60.03, 59.10, 57.75 and 55.57 g/d for Sesbania grandiflora, Leucaena leucocephala, Erythrina orientalis and Morus alba, respectively) compared to that of control group (39.25 g/d) . However, there were no significant differences in weight gain of the animals fed different tree forage based diets. Feed conversion efficiency (kg feed/kg gain) also showed that animals fed tree forage based diets presented significantly (p<0.01) higher efficiency (11.74, 12.05, 12.21 and 12.02) for L. leucocephala, E. orientalis, S. grandiflora and M. alba compared to that (16.00) of fed control diet. Nitrogen balance trial showed that there were significant (p<0.05) differences among the mean values in terms of total N intake (g/d), nitrogen retention (%) and nitrogen balance (g/d). It may be concluded that supplementation of diets with tree forages resulted in better weight gain, digestibility and nitrogen balance compared to green grass. So, the diets of goats may be supplemented with tree forages of S. grandiflora, L. leucocephala, E. orientalis and M. alba for improved growth performance.Asian J. Med. Biol. Res.

One of the goals of the experiment is to standardization of HgCl2 treatment for explants sterilization. The objectives also include developing a reproducible cost effective protocol for large scale production of Solanum tuberosum of Cardinal variety plantlets from selectively better clones through plant in vitro propagation methods. Selection of growth regulators for proper multiple shoots regeneration, elongation and root induction. To produce genetically uniform plantlets within a short time capable surviving in natural condition raised in in vitro environment. Shoot tip and nodal segment explants from field grown plants were used as experimental materials in this investigation. All explants were cultured on Murashige and Skoog medium supplemented with various plant growth regulators. For surface sterilization of explants, HgCl2 (0.1%) for 2 minutes was found to be most effective for complete destroying of surface pathogens and getting healthy tissues. Shoot regeneration was observed from both shoot tips and nodal explants for the studied plant. Maximum number of shoot per culture (17) was recorded and it also obtained the highest average length of the shoot (5cm) in Murashige and Skoog medium containing no hormone. On the other hand 6-benzyl amino purine (0.2mg/l) in 3 media showed the highest rate of shoot multiplication (73%) and the highest average length (4cm). In case of Gibberellic acid (0.1mg/l) in Murashige and Skoog media showed its highest rate of shoot regeneration (82%) and the highest average length (4.5cm). From the overall experiment it was observed that shoot tips are more responsive for micro propagation. In root induction Murashige and Skoog medium supplemented with different concentration (0.5, 1, 1.5 and 2mg/l) of indol-3-acetic acid and kinetin. Indol-3-acetic acid and kinetin (1.5+1.5 mg/l) showed its lowest rate of root regeneration (40%) and the average length of the root (1.5 cm). On the contrary Murashige and Skoog medium with no hormone showed the rate of root regeneration (96%) and the highest average length of the root (2.5 cm). The supplemented Murashige and Skoog media with no hormone showed the best performance for root regeneration.Asian J. Med. Biol. Res. June 2015, 1(2): 297-303

Published: November 2015

An experiment was conducted at a farmers field in Bakergonj Upazilla of Barisal district from July 2014 to October 2014 to study the adaptive performance of six aman rice varieties. The varieties included in the study were BRRI dhan62, BINA dhan7, BINA dhan8, BINA dhan10, BINA dhan11, and Maloti (local). The experiment was laid out in a randomized complete block design with three replications. Variety Maloti produced highest plant height (126cm) and BRRI dhan62 produced least plant height (93cm). Variety BINA dhan7 and BINA dhan11 produced highest LAI, total dry matter (g plant-1). Yield of different rice varieties varied significantly. Variety BINA dhan11 gave the highest yield (5.033 t ha-1) which was statistically at par with that of BINA dhan7 (5.00 t ha-1) and BINA dhan8 (4.50 t ha-1), BINA dhan10 (3.933t ha-1), BRRI dhan62 (4.167t ha-1). The highest grain yields of these varieties were obtained to the highest number of bearing tillers m-2. The lowest grain yield (3.50 t ha-1) and straw yield (4.840 t ha-1) were found in Maloti. The shortest period for first flowering (66 days) was observed in BRRI dhan62. Among the varieties, the longest maturity stage (139 days) was observed in local var. Maloti. While the shortest period was observed in BRRI dhan62 (94.5 days). So, the experiment concluded that BINA dhan11 was the highest performing short duration variety followed by BINA dhan7, while BRRI dhan62 and, BINAdhan8, BINAdhan10 performed better among the short duration varieties respectively during aman season to evade cyclonic effect and for cultivating boro rice in Bakergonj Upazilla of Barisal district.Asian J.

Authors: Munsi Md Nuruzzaman , Yousuf Md Abu , Hossain Sheikh Mohammad Jahangir
Published: November 2015

Bangladesh Livestock Research Institute (BLRI) plays an important role of public service to animal welfare since the period of 1984. There are a lot of cattle with their proper records in this Institutes cattle farm but previously no report regarding the dynamics of disease prevalence was published. So this research was conducted to determine the prevalence of clinical diseases and manifestations of cattle recorded and breed susceptibility to such diseases in different seasons during the period of January 2011 to December 2014. A total of 1558 cattle (where Pabna was 906 and Red Chittagong Cattle was 652) were included under this study. Diagnoses of clinical diseases and disorders were based on clinical history, clinical findings and different laboratory tests. Among the clinical cases, the highest prevalence was determined in case of ring worm (3.11%) followed by diarrhoea (1.86%), bovine ephemeral fever (1.08%), pneumonia (0.96%), alopecia (0.81%), mange (0.37%), tympany/bloat (0.69%), fever (0.64), lameness (0.53%), arthritis (0.40%), mastitis (0.39%), malnutrition (0.26%) and posthitis (0.19%). Infectious diseases like foot and mouth disease (FMD), black quarter (BQ), anthrax and haemorrhagic septicemia (HS) were not found which may be due to regular vaccination and maintenances of strict biosecurity. In case of breed, higher prevalence (12.09%) was found in Red Chittagong Cattle (RCC) compared to Pabna (11.13%). Among the seasonal cases, winter season (5.21%) had higher prevalence than rainy season (2.26%) followed by summer season (1.65%) in case of RCC, while summer season (3.85%) had higher prevalence than winter season (3.74%) followed by rainy season (3.30%) in case of Pabna. It may be concluded that several diseases and disorders occurred in the BLRI cattle farm but major infectious diseases did not take place owing to improved management of the farm.Asian J. Med. Biol.

Effects of Catalyst Preparation on Hydrocarbon Product Distribution in Hydrocracking of the Fischer-Tropsch Product with Low Pt-Loaded Catalysts
Authors: Hanaoka Toshiaki , Miyazawa Tomohisa , Shimura Katsuya , Hirata Satoshi
Published: November 2015

For the effective production of hydrocarbon liquid fuel in the hydrocracking of the Fischer-Tropsch (FT) product, the catalytic performance of Pt-loaded catalysts with low Pt content was investigated using an autoclave at 250 °C, an initial H2 pressure of 0.5 MPa, and a reaction time of 1 h. A screening study using Pt-loaded catalysts with a Pt content of 0.1 wt. % indicated that zeolite supports were more favorable for jet fuel (carbon numbers 9–15) production than amorphous oxide supports. The small particle size of the supported Pt particles and the high amount of medium acid sites for the supports led to higher performance of the Pt-loaded zeolite catalysts. In the hydrocracking reaction over Pt catalysts using the zeolite support with the high amount of medium acid sites, the yields of the corresponding jet fuel at 0.02 and 0.1 wt. % were almost the same. Pt-loaded catalysts with a Pt content of 0.02 wt. % were prepared using water-in-oil (w/o) microemulsions and their particle size was controlled between 1.0 and 2.6 nm. While the yield of the corresponding jet fuel was independent of Pt particle size, smaller Pt particles typically promoted the production of lighter hydrocarbons.

D'Alphonse X à Alphonse XI : l'affirmation du pouvoir dans les prologues des œuvres castillanes aux XIIIe et XIVe siècles
Authors: Rochwert-Zuili Patricia
Published: November 2015

Fondé sur l’étude des pièces liminaires de quelques oeuvres composées sous les règnes d’Alphonse X, de Sanche IV, de Ferdinand IV et d’Alphonse XI, ce travail permet de suivre les différentes stratégies discursives auxquelles ces monarques eurent recours pour affirmer leur pouvoir. Ainsi perçoit-on, dans les prologues alphonsins, notamment à travers le lien qui s’établit entre les notions d’ordre et de savoir et la place accordée au roi-auctor modèle, les traits d’une évolution correspondant aux grandes phases et aux vicissitudes du règne du Roi Sage. De même voit-on comment Sanche IV et ses successeurs s’employèrent à légitimer leur pouvoir en usant de procédés s’inscrivant à la fois dans la continuité et la rupture au regard du modèle alphonsin, des procédés qui révèlent en outre le rôle que joua la reine et régente Marie de Molina dans l’affirmation de l’autorité royale.

La ville et l'effigie. Emblématique et identités urbaines dans le Nord de la France au XXe siècle.
Authors: Gueusquin Marie-France
Published: November 2015

Cet article est le résultat d'une enquête menée dans six localités de la région du Nord/Pas-de-Calais (Comines, Wasquehal, Noyelles, Cassel, Godewaersvelde et Maubeuge), sur l'appréhension du processus de formation des identifications communautaires urbaines. Pour cela nous partons d'un type de production symbolique commun à la région, les géants rituels. L'étude de ces emblèmes est intéressante dans le sens où par leur diversité ils vont nous fournir des informations extrêmement fines sur le fondement même de l'identité collective urbaine. La création de ces images est souvent à mettre en relation avec l'histoire d'un site, d'une pratique professionnelle interrompue ou d'individus liés à un territoire, mais disparus eux aussi. Cette valorisation du passé contribue à accorder à ces monumentales constructions une fonction commémorative qui les situe au cœur d'une histoire collective.

La conception de ces images est le fait de groupements déclarés avant pour but l'organisation de la vie festive locale. En prenant de telles initiatives de création, les groupes producteurs de mannequins rituels jouent sans contexte un rôle de tout premier plan concernant la formation de l'identité locale, l'élaboration supposant de leur part une bonne connaissance du patrimoine historique, culturel, voire anedoctique du lieu. Identité quelque peu forcée dans la mesure où le modèle choisi n'est pas consensuel pour tous, sauf bien sûr à l'intérieur de l'association dont il soutient les valeurs propres.
VISCOELASTIC MODULUS RECONSTRUCTION USING TIME HARMONIC VIBRATIONS
Authors: Ammari Habib , Seo Jin Keun , Zhou Liangdong
Published: November 2015

This paper presents a new iterative reconstruction method to provide high-resolution images of shear modulus and viscosity via the internal measurement of displacement fields in tissues. To solve the inverse problem, we compute the Frechet derivatives of the least-squares discrepancy functional with respect to the shear modulus and shear viscosity. The proposed iterative reconstruction method using this Fr´echet derivative does not require any differentiation of the displacement data for the full isotropic linearly viscoelastic model, whereas the standard algebraic inversion method requires at least double differentiation. Because the minimization problem is ill-posed and highly nonlinear, this adjoint-based optimization method needs a very well-matched initial guess. We find a good initial guess. For a well-matched initial guess, numerical experiments show that the proposed method considerably improves the quality of the reconstructed viscoelastic images.
Siegfried Kracauer et la « métaphysique du roman policier »
Authors: Cohen-Halimi Michèle
Published: November 2015

Brillant analyste de la vie sociale et culturelle de l’Allemagne des années vingt et trente, Siegfried Kracauer montre dans son essai Le Roman policier comment l’inscription dans une culture de masse du genre littéraire récent qu’est le « roman policier » procède d’une mutation radicale de la rationalité et des conditions « métaphysiques » de la constitution du sens. C’est étonnamment en adoptant une perspective métaphysique que Siegfried Kracauer parvient à faire des transformations du roman policier les prodromes de la terreur totalitaire qui vient.
L’agir et le faire chez Hannah Arendt : réflexions et prolongements
Authors: Jesuha Thomas
Published: November 2015

Dans cet article, nous voudrions mettre en relief un aspect de la pensée d’Hannah Arendt qui n’est pas souvent dégagé pour lui-même, à savoir la critique que toute sa pensée adresse à ce qu’on nommera la dimension poïétique de l’activité humaine. En effet, Arendt ne cesse de critiquer les tentatives aussi bien philosophiques que politiques par lesquelles l’homme cherche à exporter l’acte de fabrication hors de son lieu artisanal – fabriquer un corps politique, fabriquer un nouvel homme, fabriquer un nouveau monde. Dans les conditions contemporaines où la technique occupe une place sans cesse grandissante, il importe de s’interroger sur la pertinence d’une telle critique et d’en explorer quelques conséquences.
La nature, le moi et le genre : féminisme, philosophie environnementale et critique du rationalisme
Authors: Plumwood Val , Afeissa Hicham-Stéphane
Published: November 2015

L’auteure répond aux critiques adressées par les philosophes féministes à la philosophie environnementale. Le problème viendrait du fait que celle-ci ait repris des hypothèses issues d’analyses, rationalistes et ethnocentrées, biaisées par un préjugé de genre, concevant la raison comme radicalement distincte du corps et des émotions et appelée à exercer un contrôle sur celles-ci, les femmes, le corps et la nature. Au contraire de la thèse identifiée comme celle du moi divisé, l’auteure développe l’idée que ce qui nous est proche ou personnel ( nos arbres, nos rivières) joue un rôle central dans l’acquisition d’une vie morale et d’une sensibilité à l’environnement, en consonance avec les approches féministes d’un moi-en-relation. Rejetant la deep ecology qui poserait le problème d’une métaphysique de l’indifférenciation, l’auteure propose une conceptualisation des relations intrinsèques à l’humain, invitant à dépasser la théorie de la ‘séparation’ masculine et les théories traditionnellement féminines de la ‘fusion’.
« Extrême violence » et « citoyenneté/civilité » (Balibar). Le pari tragique de la convertibilité/inconvertibilité
Authors: Caloz-Tschopp Marie-claire
Published: November 2015

La transformation du capitalisme n’a pas le rythme du déplacement des planètes. C’est une course automobile effrénée dans un temps compressé. Son « moteur », - la violence, l’extrême violence - s’étend à l’espace planétaire surexploité, saccagé. Elle tend à effacer la possibilité de la politique et de la philosophie explique Balibar, qui pose le pari tragique que la convertibilité/inconvertibilité de la violence en civilité dans un sens post-hégélien est possible mais pas garantie. C’est le pari irréductible de l’altérité, de la relation, contre celui de la tentation de l’absolu illimité , abîme où l’extrême violence nous attire. Changement de lieu, de paradigme : on passe alors d’une métaphysique déterministe du limité/illimité à une philosophie, une anthropologie politique du possible/impossible à la portée d’humains prenant en compte leur part d’inhumain dans l’action imprévisible.
Les possibilités d’inventer la politique malgré la « violence extrême » (Étienne Balibar)
Authors: Selek Pinar
Published: November 2015

L’examen de l’espace militant en Turquie permet de mettre à l’épreuve une perspective dynamique en montrant à la fois l’influence de l’environnement sur l’action collective et le caractère non structurel, relationnel, dynamique et par conséquent complexe de celle-ci. L’analyse de cet espace, en renvoyant à une pluralité d’expériences, donne maintes occasions de comprendre comment les différents mouvements contestataires, malgré la répression, co-construisent les contextes et se co-construisent. En 1980, un nouveau cycle de contestation apparaît, et ce, malgré la répression meurtrière. Celui-ci entraîne plusieurs innovations dans le répertoire et les modalités d’organisation et d’action. Dans un contexte de crise, ce registre d’action non partisan avec sa fluidité, renforce la capacité de l’anti-violence.
Les stratégies de civilité : une politique des identités ?
Authors: Lavergne Cécile
Published: November 2015

L’extrême violence est fondamentalement ce à partir de quoi Étienne Balibar propose de repenser le politique dans son ouvrage Violence et Civilité . Et cette refondation, il ne la conçoit pas en dehors du nœud problématique qui unit le problème de la violence et le problème des identités. Le pari de la politique de civilité consiste à penser une politique, non pas qui écarte toute violence, mais qui empêche le franchissement du seuil de l’extrême violence. Or, la civilité ne peut se réduire à une politique des identités. Car elle appelle une réflexivité critique des acteurs politiques sur leurs identités. C’est cette réflexivité critique que nous nous proposons de clarifier en prolongeant les analyses de Balibar par une politique des corps et des affects, à partir d’analyses de Judith Butler sur la Révolution égyptienne.
Pedicle Internal Limiting Membrane Transposition Flap Technique for Refractory Macular Hole
Authors: Gekka Tamaki , Watanabe Akira , Ohkuma Yasuhiro , Arai Kota , Watanabe Tomoyuki , Tsuzuki Akane , Tsuneoka Hiroshi
Published: November 2015

BACKGROUND AND OBJECTIVE:

To determine the efficacy of the pedicle internal limiting membrane (ILM) transposition flap technique for refractory macular holes (MHs) in which the inverted ILM flap technique cannot be performed.

PATIENTS AND METHODS:

The pedicle ILM flap transposition technique was conducted by transconjunctival microincision vitrectomy. The authors attempted to peel the remaining ILM inferior from the MH to create an ILM flap. This ILM was still attached to the retina at the upper part of the MH and covered the MH. Finally, fluid-gas exchange was performed. After surgery, patients remained face-down for 1 week. This procedure was performed in two eyes.

RESULTS:

There were no adverse events, and MHs were closed successfully in both study eyes.

CONCLUSION:

The pedicle ILM flap transposition technique has the potential to improve functional and anatomical outcomes in patients with refractory MHs.

Optical Coherence Tomography Follow-up of an Unusual Case of Old Rhegmatogenous Retinal Detachment With a Hemorrhagic Macrocyst at the Macula
Authors: Tripathy Koushik , Bypareddy Ravi , Chawla Rohan , Kumawat Babulal
Published: November 2015

A 32-year-old female presented with visual acuity of hand movement close to face, an old inferior rhegmatogenous retinal detachment (RRD), and a large hemorrhagic macular macrocyst (HMM) in the right eye. After 2 weeks of successful vitreoretinal surgery, the HMM started decreasing in height and resolved by 3 months. On optical coherence tomography, a zone of hyperreflectivity in the outer retinal layers was evident on resolution of the cyst. At final follow-up, the visual acuity improved to 1/60 only. Though HMM resolved completely after retinal reattachment, alteration and thickening of microarchitecture of the outer retinal layers ensued.

Spectral-Domain Optical Coherence Tomography of Polypoidal Choroidal Vasculopathy Associated With Benign Choroidal Nevus
Authors: De Salvo Gabriella , Vaz-Pereira Sara , Sehmi Kulwant S. , Andrews Richard M. , Sagoo Mandeep S.
Published: November 2015

Two cases of polypoidal choroidal vasculopathy (PCV) complicating benign choroidal nevus and their tomographic features at spectral-domain optical coherence tomography (SD-OCT) are reported. Two eyes with choroidal nevus and associated subretinal fluid underwent complete ophthalmological examination, SD-OCT, fundus fluorescein angiography, and indocyanine green angiography (ICGA). SD-OCT and ICGA confirmed the diagnosis of PCV in both cases. Ophthalmologists should be aware of this rare combination between choroidal nevus and PCV. If a choroidal nevus presents with subretinal fluid, this does not always herald malignant transformation, and PCV should be ruled out so that the correct treatment can be planned.

Positive Auto-Antibody Activity With Retina and Optic Nerve in Smokers and Non-Smokers: The Controversy Continues
Authors: Chin Eric K. , Almeida David R. P. , Lam Khoa V. , Keltner John L. , Thirkill Charles E.
Published: November 2015

Auto-antibodies assist with the diagnosis of ocular paraneoplastic syndromes and autoimmune ocular conditions; however, the frequency of positive test results as a possible precursor to future disease is unknown. The frequency of positive antibodies in heavy smokers who may be at risk for autoimmune-related retinopathy and optic neuropathy was evaluated. Serum antibody activity was evaluated through the use of Western blot reactions from pig retina and optic nerve extract. Fifty-one patients were included: 35 patients were smokers (average: 40.9 pack-year history) and 26 patients had no past smoking history. None of the patients had any visual complaints or known eye disease. Of the patients studied, 76.5% (39 patients: 18 smokers, 21 non-smokers) had positive antiretinal antibodies, and 19.6% (10 patients: 3 smokers, 7 non-smokers) had positive antioptic nerve antibodies. Anti-retinal antibodies were seen in a majority of randomly selected patients with and without a past smoking history. Anti-optic nerve bodies were less common, but more prevalent in those who never smoked. The specificity of these antibodies remains greatly uncertain and clinical correlation is warranted.

L’égalité en matière d’héritage. Jeunes et savoir commun au Maroc
Authors: Yafout Merieme
Published: November 2015

L’objectif de cet article est de mettre en évidence le savoir d’un petit échantillon de jeunes marocains à propos de la règle d’héritage qui permet aux garçons d’hériter la double part de leurs sœurs après le décès du père. Ainsi, je relèverai le vocabulaire, les arguments, les opinions que ces jeunes développent concernant cette règle. Je considérerai alors comment le savoir commun des jeunes s’articule aux différents lexiques de la culture savante et aux positions vis-à-vis de ladite règle d’héritage. Par ailleurs, le savoir que ces jeunes expriment est aussi lié à des acquis socioculturels qu’ils manifestent sous forme de discours spontané, accessible et évident sur les relations hommes/femmes, sur la famille, sur la division des rôles sociaux, sur la place de la religion dans la société. Il s’agit d’un savoir organiquement lié à la vie quotidienne d’une manière qui oriente les actions dans la vie de tous les jours et permet de comprendre le sens que les gens donnent à leurs agissements.
Orbital Forming of Flange Parts under Uncertainty
Authors: Calmano Stefan , Hesse Daniel , Hoppe Florian , Traidl Philipp , Sinz Julian , Groche Peter
Published: November 2015

Uncertainty in the properties of semi-finished parts can cause fluctuations in the product properties, especially if they have a strong effect on the process and cannot be compensated by process adjustments. Incremental forming processes have the potential to react to changing conditions by adapting the tool movement during the process. This paper analyzes the feasibility of controlling material flow in an orbital forming process in order to selectively fill those geometric elements which were specified with narrow tolerances by the designer. The effect of different process parameters on the mushroom effect and the degree of mold filling are analyzed by FEM simulations and experiments. In order to realize online monitoring and control, an estimation model is introduced, which maps signals from sensors and the process control to the geometric target values.
Methodical Approaches to Describe and Evaluate Uncertainty in the Transmission Behavior of a Sensory Rod
Authors: Melzer Christiane Marianne , Krech Martin , Kristl Lisa , Freund Tillmann , Kuttich Anja , Zocholl Maximilian , Groche Peter , Kohler Michael , Platz Roland
Published: November 2015

Load carrying mechanical structures like trusses face uncertainty in loading along with uncertainty in their strength due to uncertainty in the development, production and usage. The uncertainty in production of function integrated rods is investigated, which allows monitoring of load and condition variations that are present in the product in every phase of its lifetime. Due to fluctuations of the semi-finished parts, uncertainty in governing geometrical, mechanical and electrical properties such as Young's moduli, lengths and piezoelectric charge constants has to be evaluated. The authors compare the different direct methodical approaches Monte-Carlo simulation, fuzzy and interval arithmetic to describe and to evaluate this uncertainty in the development phase of a simplified, linear mathematical model of a sensory rod in a consistent way. The criterion to compare the methodical approaches for uncertainty analysis is the uncertain mechanical-electrical transmission behavior of the sensory rod, which defines the sensitivity of the sensory compound.

Published: November 2015

CAD technology has introduced a turning point in the way of design. In the period before the introduction of computer systems, drafts were traditionally made by pen and each mistake meant erasing, whereas bigger mistakes often required re-creation of the anatomical documentation. The closely linked development of CAD/CAM technology marked the upturn in obtaining the anatomic shape and its creation. This article gives a brief insight into 3D digitization in the field of making the anatomic insole.

Currently, when design engineering ensures operational security by fully taking into account reliability studies, it is of primary importance to have an encompassing understanding of the welding processes and all implicit problems that may arise, not only during their implementation phase but also after completion, in order to be able to avoid material losses. It is also necessary to have a full understanding of the imperfections that may occur in welded joints, their causes and the impact they can have on the operating endurance of the products, in order to be able to accurately determine if a product meets the required quality criteria. Thus, the development of software applications which can provide information regarding welding processes may be an important achievement for the education and industry. The software application presented in this paper provides information on the description of welding processes, welding parameters selection and calculation, types of materials and their classification in groups, as well as information about the types of imperfections, their causes, limits of acceptability and non-destructive examination methods for welded joints.

Published: November 2015

Nowadays, managers recognize the impact that measures have in performance. The balanced scorecard is a new tool that complements traditional measures of business unit performance. The scorecard contains a diverse set of performance measures, including financial performance, customer relations, internal business processes, and learning and growth.The Balanced Scorecard provides leaders with a process to describe strategy – both what the organization wants to accomplish and how it intends to realize its strategic outcomes. Taking all the objectives and measures together into a strategy map of cause-and-effect relationship across the four perspectives provides a comprehensive picture of the organization’s value creating activities.The analysis developed in this paper aims is to examine the critical areas of an industrial system as product, process, customer and market perspective. The study will provide managers four different perspective from which to choose measures: from traditional financial indicators, to measures for improving customer satisfaction, internal processes and innovation and improvement activities, focusing on the company’s current and future success.

Different Methods of Artificial Intelligence Used for Optimization the Turning Process
Authors: Cofaru Nicolae , Florea Adrian
Published: November 2015

In this paper, we realize a comparative study between some heuristics methods applied in turning operation in order to find optimal cutting parameters. We consider five different constraints aimed to achieve minimum total cost of machining. We have chosen the Simulated Annealing (SA) – a local search method, and Weighted-Sum Genetic Algorithm (WSGA) – a non-Pareto approach of a multi-objective optimization algorithm, based on a weighted aggregation of objectives. The aggregation may be with fixed weights or with random (variable) weights. The simulations showed that, even if it produces better results than the SA, WSGA with fixed weights, does not lead to optimum results, highlighting in this way that in the formula of the cost function, some cost components may be more important than others. In addition, we extend our previous work by integrating in the software application a new optimization method: WSGA with random weights. Also, we increase the application’s flexibility by reconfiguring the graphical user interface in order to allow tuning the optimization techniques parameters.

Promoting technological entrepreneurship in Romania is essential to support sustainable development in the actual context of a slow recovery after the recent crises and turbulences. SMEs have gone through a difficult period and the ones that remained on the market have demonstrated solidity and an adequate, based on flexibility, response to market movements. In emerging markets SMEs represents innovative vectors equipped with capabilities, knowledge, strategies and organizational development. Considering the low efficiency recovery after the crises and turbulences due to the volatility of global business (constantly changing customer expectations and identity, disruptive technological change, acceleration of innovation-based competition, market orientation for higher returns) we can see a good potential for Romanian technological SMEs. The main problem is related to the financing. The banking system is not interested in these types of projects and the capital market is still inaccessible for this type of investments. The government efforts to solve this problem are limited by the lack of appropriate tools, markets and institutional architecture. In this case is necessary to analyze new innovative financing solutions better adapted to the current dynamics of the technological entrepreneurship. An analysis of the possibilities to develop innovative solutions based on market functionality and institutions is presented. The focus is on natural, sustainable and flexible solutions, based on market mechanisms. The implementation of innovative financing solutions for technological SMEs is a very complex initiative, but the results will be visible immediately, contributing decisively to the development of entrepreneurship.
Edge Effect on Analysis of Residual Stresses in Steel Welded Parts Using Ultrasounds
Authors: Dușa Petru , Lupașcu Radu Baciu , Purice Eugen
Published: November 2015

Our past research to estimate residual stress into steel welded parts was based on dependence between sound velocity and elastic modulus using longitudinal sound wave. To conduct the experiments was designed sample as a frame. The sample was loaded using adapted equipment and the results were used for FEA tools (SolidWorks SimulationXpress) to obtain the distribution of stresses and displacements. This approach allowed the location of points of interest to the investigation with ultrasound. During the experimentation we arrived to suspect the influence of marginal effect on analysis of residual stresses in steel welded parts using ultrasounds. New experiments were carried out by using part samples permitting to avoid the marginal effect.
Adapting the Existing District Heating Systems to Dynamic Operating Conditions
Authors: Lefter Răzvan Corneliu , Popescu Daniela
Published: November 2015

District heating systems operating under dynamic conditions without proper hydronic balancing is one of the causes of discomfort for heating consumers. Moreover, from the point of view of producers, unbalanced heating networks generate low energy efficiency. The study analyzes the operation conditions in three cases, on the same network: the first simulates the operating conditions of the network without balancing, the second when just balancing valves set to corresponding nominal flow rate values are used and the third when balancing valves and differential pressure controllers are used, the so-called total balancing method. Results highlight the importance of the hydraulic balancing under steady state and dynamic operating conditions, as a source to increase the energy efficiency and assure thermal comfort by better distribution of fluid flow rates between consumers.

Published: November 2015

Precision of the machining centers is influenced by many factors among which are mechanical vibrations that occur in the machine-tool-part-device system. Evaluation of vibration level for five axes machining centers is a very important issue considering structural and functional complexity of these equipments. The paper presents researches performed at University of Oradea to evaluate vibration of TMA-AL 550 five axes machining center, equipped with a two rotating axes table, during the machining process. There have been used two methods: evaluation of the dynamic behavior of the spindle using a laser vibrometer and evaluation of mechanical vibrations of the five axes machining center using triaxial accelerometers. Measurement data had been processed using spectral analysis and time-frequency parameters, revealing frequency domains which can cause high amplitudes of vibration. Results also show that the measured vibration levels are not exceeding the accepted limits.

Aims of this project are the identification of new compounds that inhibit Aspergillus proliferation, the development of new inhibitors of aflatoxins production, and the set-up a practical screening procedure to identify the most effective and safe compounds.

Design and Methods

New compounds will be synthetized with natural origin molecules as ligands and endogenous metal ions to increase their bioavailability for the fungi as metal complexes. A biotechnological high-throughput screening will be set up to identify efficiently the most powerful substances. The newly synthesized compounds with effective antifungal activities, will be evaluated with battery of tests with different end-points to assess the toxic potential risk for environmental and human health.

Expected impact of the study for public health

The fundamental step in the project will be the synthesis of new compounds and the study of their capability to inhibit aflatoxin biosynthesis. A new, simple, inexpensive and high-throughput method to screen the anti-fungine and anti-mycotoxin activity of the new synthesised compounds will be applied. The evaluation of possible risks for humans due to toxic and genotoxic activities of the molecules will be made with a new approach using different types of cells (bacteria, plants and human cells).
