since it is not a routine operation. In this context it is important to identify and
study certain common characteristics of an effective project manager. The aim of
this research is to examine the importance of the attributes of an effective project
manager by analyzing how satisfied his/her collaborators are. The study focuses on
the project management of EU Operational Programs in the public sector. Based
on the literature, the effective project manager should be able to understand and
influence the key parameters of any project (physical, technical, scientific, etc.), such
as the duration, the financial resources, the human resources, the legislation, and
the operation. To analyze the degree of satisfaction and the importance of project
manager characteristics, the MUSA method has been applied, which is a multiplecriteria
decision-analysis approach in the field of preference disaggregation.

Changes in color, water vapor permeability, porosity, pore size distribution and tensile strength were evaluated after treatment. Energy Dispersive X-ray Fluorescence (EDXRF) indicated that the products reached a depth from the surface of 30mm and were evenly distributed inside the stone, except for LD, which accumulated up to the first 10mm from the surface. Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) showed that linkages created between limestone and gels, due to the hydroxyl groups of the quartz and aluminosilicate minerals included in the limestones. PP and LD reduced the water vapor permeability coefficient to acceptable limits and induced the least chromatic variation. Mercury intrusion porosimetry (MIP) results indicated that the precipitation of the formed gel increased the specific surface area. The porosity and pore size decreased in the treated bioclastic limestones and in the KS and LD treated sandy limestones. In contrast, the PP and PP+HP treated sandy limestones showed an increase in porosity and average pore radius, as a result of the polymer cracking. When polymers were applied to the sandy limestones of large pore radii, the formed gels underwent cracking from drying shrinkage and the mechanical resistance of the stone was reduced. The gels when deposited in the small pore radii of bioclastic limestones behaved as thin films, thereby no cracking was induced by the consolidant from drying shrinkage. This study demonstrated that the performance of a consolidant is greatly dependent on the pore size of the stone. None of the above studied products can be recommended for consolidation of the sandy limestones, while the elastified silicic acid ethyl ester (PP) is only recommended for consolidating the bioclastic limestones.

This study aimed at investigating the effects of this temperature decline within a certain time frame, the type of culture dish with or without the use of laminar air flow and whether it is possible to achieve a sufficient thermal control with the use of a heating stage. Materials and Methods In this experimental study, the temperatures of four different types of polystyrene dishes [50 mm intracytoplasmic sperm injection (ICSI), 35 mm, 60 mm, 90 mm], filled with culture medium and oil were recorded for a period of 10 minutes outside the incubator. Temperature was measured with an infrared thermographic camera. The reference temperature was 37°C. Four parameters were analyzed: the type of dishes, air flow, a heating stage at 37°C and 38.5°C. Results There was a time-dependant significant temperature decline outside the incubator in all types of dishes and under all exp...
