Deciphering the metamorphic evolution of the Pulo do Lobo metasedimentary domain (SW Iberian Variscides)
No full textThe Pulo do Lobo domain is one of the units exposed
within the orogenic suture zone between the Ossa-
Morena and the South Portuguese zones in the SW Iberian
Variscides. This metasedimentary unit has been classically
interpreted as a Rheic subduction-related accretionary prism
formed during pre-Carboniferous convergence and eventual
collision between the South Portuguese Zone (part of Avalonia)
and the Ossa-Morena Zone (peri-Gondwanan terrane).
Discrete mafic intrusions also occur within the dominant
Pulo do Lobo metapelites, related to an intra-orogenic Mississippian
transtensional and magmatic event that had a significant
thermal input. Three different approaches have been
applied to the Devonian–Carboniferous phyllites and slates
of the Pulo do Lobo domain in order to study their poorly
known low-grade metamorphic evolution. X-ray diffraction
(XRD) was used to identify the mineralogy and measure
crystallographic parameters (illite “crystallinity” and Kwhite
mica b-cell dimension). Compositional maps of selected
samples were obtained from electron probe microanalysis,
which allowed for processing with XMapTools
software, and chlorite semiempirical and thermodynamic
geothermometry was performed. Thermometry based on Raman
spectroscopy of carbonaceous material (RSCM) was
used to obtain peak temperatures.This research has been supported by the Spanish

Comment on ‘‘Stratigraphy of the Northern Pulo do Lobo Domain, SW Iberia Variscides: A palynological contribution’’ by Zelia Pereira et al. (2018) – Geobios 51, 491–506
No full textThe paper by Zelia Pereira et al. (2018) is a valuable input to
better constrain the Devonian palynological record of a number of
siliciclastic formations of the Pulo do Lobo Unit (also known as Pulo
do Lobo Domain or Pulo do Lobo Zone) in SW Iberia. They have
recognized for the first time in the Pulo do Lobo Fm. and in the
imbricated phyllites of the Peramora Me´lange palynomorph
assemblages assigned to the middle Frasnian, as well as new
Devonian palynomorphs in the Ribeira de Limas, Santa Iria and
Horta da Torre formations, and the Alajar Me´ lange. Furthermore,
Ze´ lia Pereira et al. (2018) intend to promote a ‘‘detailed discussion of
the palynological versus geochronological ages by comparing their
biostratigraphic ages with the maximum depositional ages
inferred for the same formations according to detrital zircon
geochronology (Pe´rez-Ca´ ceres et al., 2017; Pereira et al., 2017). The
purpose of their discussion is to question the validity of zircon
geochronological data, which allegedly would be contradictory
with the palynomorph content, and thus not compatible with the
established stratigraphic sequence. In our view, this discussion is
inconsistent due to:
i) the impossibility that primary igneous ages in zircon grains
would have been rejuvenated during Early Carboniferous low-
grade regional metamorphism;
ii) a wrong interpretation of the meaning and implications of
maximal depositional ages derived from the youngest detrital
zircon population

Dependence of unsaturated chloride diffusion on the pore structure in cementitious materials
No full textConceptual analysis is performed to examine the effects of pore features on the water continuity in unsaturated porous systems. The roles of pore features in relative chloride diffusion coefficient (Drc) of mortar specimens at various degrees of water saturation (Sw) were studied based on mercury intrusion porosimetry and resistivity tests. It is found that the role of pore structure in the Drc-Sw relationship is a result of its effect on the water continuity. Porosity and tortuosity are not relevant to the Drc-Sw relationship. A finer pore size distribution or lower pore connectivity tends to result in a lower Drc. The pore size effect on the Drc is pronounced primarily at high Sw, while the Drc is dominated by the pore connectivity at low Sw. Cement mortar with a higher water-to-binder ratio shows larger chloride diffusion at high relative humidity levels but smaller chloride diffusion at low relative humidity levels.Accepted Author ManuscriptMaterials and Environmen
Total Cost of Ownership for Application Replatform by Open-source SW
No full textAbstractIn intra-company IT environment, the use of open-source software (OSS) should be expanded to reduce IT costs and to establish SW governance. This requires the migration of systems from the existing commercial SW to open-source SW, but the attempt of application replatform is prevented by the expenses for application reprogramming and data migration. This study proposes a methodology for TCO calculation of application replatform using open-source SW. In practice, a five-year TCO shows a cost reduction effect of 78% - 83%. This TCO could be further reduced if the application size is increased due to data accumulation and the company gets open-source SW capabilities internally. In addition, it is possible to directly apply an application developed from open-source SW to a virtualized infrastructure environment, which enables to operate in a hybrid cloud environment. This enables a scalable, efficient and flexible IT operation and a sustainable TCO reduction in the futur

Change management of the SW projects in the small and medium business
No full textThe bachelor thesis focuses on SW projects, ways of their management and mainly change management in the small and medium business. This thesis is devided into two parts. Author deals with SW projects and most common mistakes during their development in the theory part. The main aim of this part is to refer to these mistakes the reader, who is interested in SW projects. Next, there is a comparision of the two famous methodics, which are well-known in the SW development. These are ITIL and RUP. Author will choose the one, which will be more acceptable for the Cleverdecision. At this time, Cleverdecision has no change management and every change during the SW development is managed by contracting condition. That is why author formulates the ways of change management in the practical part. This will be based on the chosen methodics from the theory part. This formulation is the main aim of this thesis. The contribution of the thesis is in the definition of the change management workflow and in the proposition of the templates for setting the change requests. These templates are sufficient for unification concepts and easier specification of the change requests. Insertion of the change management into the contract is part of the thesis as well
