Towards Cloud Management by Autonomic Manager Collaboration  [PDF]
Omid Mola, Michael A. Bauer
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.432097
Abstract: The management of clouds comprised of hundreds of hosts and virtual machines present challenging problems to administrators in ensuring that performance agreements are met and that resources are efficiently utilized. Automated approaches can help in managing such environments. Autonomic managers using policy-based management can provide a useful approach to such automation. We outline how collections of collaborating autonomic managers in cloud can be a step towards better management of clouds. We describe how a hierarchy of policy-based autonomic managers can collaborate using messages. The messages and when to communicate is inferred automatically from the policies given to the managers. We evaluate the approach via a prototype inspired by a cloud virtualized infrastructure and show how collaboration between managers in a hierarchy can improve the response time of a web server and avoid service level agreement violations. Results of three different scenarios shows the importance of collaboration between managers at different authority levels and how this collaboration can help to increase efficiency of current infrastructures.
Seasonal and spatial distribution of Brachionus (Pallas, 1966; Eurotatoria: Monogonanta: Brachionidae), a bioindicator of eutrophication in lake El-Manzalah, Egypt
HRA. Mola
Biology and Medicine , 2011,
Abstract: Rotifers, especially Brachionus sp., are the major component of zooplankton in Egyptian eutrophic lakes. Thesespecies play an important role as bioindicator in these aquatic environments. In present study, twenty-fourzooplankton samples were collected and investigated along six stations of southeastern sector of the lake fromAugust 2009 to May 2010. Brachionus sp. were the most abundant species constituting 74.8 % of the total rotifersand 59.87 % of the total zooplankton. It was represented by 7 species which are; Brachionus angularis, B.budapestinensis, B. calyciflorus, B. caudatus, B. plicatilis, B. urceolaris and B. quadridentatus. The highestabundance of Brachionus sp. was recorded at Ibn Salam Station (4227493 Org./m3) during summer due to the effectof water discharge rich in nutrients through 3 main drains in this area while the lowest abundance was recorded at El-Qaboti Station (333 Org./m3) during winter. Brachionus angularis and B. calyciflorus formed collectively (92.16 % ofthe total Brachionus sp.). The presence of these species of Brachionus in high composition indicates eutrophicationof Lake El-Manzalah.
Fabrication and Microstructure of Layers Containing Intermetallic Phases on Magnesium
R. Mola
Archives of Foundry Engineering , 2013,
Abstract: Al- and Al/Zn-enriched layers containing intermetallic phases were deposited on the Mg substrate by heating the Mg specimens in contactwith the powdered materials in a vacuum furnace. The Al-enriched surface layers were produced using Al powder, whereas the Al/Znenriched layers were obtained from an 80 wt.% Al + 20 wt.% Zn powder mixture. The microstructure and composition of the layers wereanalyzed by optical microscopy, scanning electron microscopy and X-ray diffraction. The results showed that the Al-enriched layercomprised an Mg17Al12 intermetallic phase and a solid solution of Al in Mg. The layer obtained from the Al+Zn powder mixture wascomposed of Mg-Al-Zn intermetalic phases and a solid solution of Al and Zn in Mg. Adding 20% of Zn into the Al powder resulted in theformation of a considerably thicker layer. Moreover, the hardness of the surface layers was much higher than that of the Mg substrate.
Convergence to equilibria for a three-dimensional conserved phase-field system with memory
Gianluca Mola
Electronic Journal of Differential Equations , 2008,
Abstract: We consider a conserved phase-field system with thermal memory on a tridimensional bounded domain. Assuming that the nonlinearity is real analytic, we use a Lojasiewicz-Simon type inequality to study the convergence to steady states of single trajectories. We also give an estimate of the convergence rate.
Fantasia e conhecimento: um estudo crítico preliminar
Mola, Luis Guilherme Coelho;
Psicologia USP , 1999, DOI: 10.1590/S0103-65641999000200003
Abstract: the purpose of this article is to discuss the role played by imagination in the process of knowledge production. using as theoretical support the ideas of some philosophers of the frankfurt school, the text attempts to demonstrate that imagination has a critical function, denied by positivism, which could contribute for the questioning of the organization of society.
L'ús de la norma de qualitat ISO 9001 a les biblioteques d'institucions d'educació superior

Formation of magnesium-eutectic mixture layered composite
R. Mola,A. Dziadoń
Archives of Foundry Engineering , 2008,
Abstract: The work was started from study of the structural transformations, that in elevated temperatures, take place at the magnesium-aluminium interface. It was found experimentally that at temperature of 445oC solid state diffusion is followed by liquid phase appearance at the Mg-Al interface. For process passing with the liquid phase contribution thickness d of the reactions products against the time t can be expressed by the equation d=Atn with the time exponent value n>1. This process is very fast compared to solid state polyphase diffusion and can be controlled, therefore may be used for fabrication of layered composite. To obtain a composite, magnesium and aluminium sheets are formed alternately into a pocket and then heated at temperature of 445oC. Heating is prolonged for passing all the aluminium with part of the magnesium sheets into a liquid phase. During solidification liquid phase is transformed into eutectic mixture. So, composite that was formed consists of alternating magnesium and eutectic mixture layers. Using X-ray microprobe analysis and on the basis of Mg-Al binary phase diagram we were found that the eutectic mixture contains two phases: Mg17Al12 intermetallic compound and solid solution of aluminium in magnesium.
Infliximab-induced intertriginous psoriasis in patient with Crohn's desease
Federica Mola,Alberico Motolese
Dermatology Reports , 2011, DOI: 10.4081/dr.2011.e40
Abstract: Tumor necrosis factor-α (TNFα) inhibition is an effective treatment of moderate-to-severe psoriasis and other diseases (rheumatoid arthritis, ankylosing spondylitis, psoriasis or Crohn’s disease). We report a case of a 32- years-old patient affected by Crohn’s disease since the age of 25 who started infliximab infusion after four years of treatment with prednisone and azathioprine per os without improvement. After the fifth infusion of infliximab, he developed a form of intertriginous psoriasis which was approached with topical steroid cream. The patient never presented psoriasis in the past. New onset of psoriasis in patients without history for skin diseases (as in our case) is a quite uncommon complication of TNFα inhibitor therapy. The increased production of IFNα during TNFα inhibitor therapy is a possible pathophysiologic explanation for this paradoxical effect of the anti-TNFα.
