There was a significant reduction in the number of papules, pustules, and comedones in Groups A and V compared with those in the control group (p < 0.001) with a more rapid decrease of the papules from Group A compared with that from Group V. We found an improvement in the clinical aspect (p < 0.001) when we compared Groups A and V with controls. Patients belonging to Group A were more satisfied compared with those belonging to Group V (p = 0.004) and significantly more satisfied compared with those belonging to Group 0 (p < 0.001). In conclusion, we consider that both the devices are efficient, the combination of vacuum and IPL representing a therapeutic option for the comedonal acne.

Active House is a vision on some buildings that create a healthy and comfortable life for their occupants without influencing in a negative way the climate and environment - leading to a cleaner, healthier and safer world. Active House proposes a target framework for changing the way we build and renovate buildings in order to contribute positively to our health, safety and well-being, focusing on indoor and outdoor environment and on the effective use of energy.

Biofuels are considered to be attractive alternative fuels due to rising oil prices and the depletion of fossil sources. It is produced by a process of transesterification of vegetable oils and animal fats with an alcohol in the presence of a catalyst. At present, biodiesel and bioethanol are considered solutions, and almost all EU countries have prepared a policy on the production and use of biodiesel in the transport and heating sectors. Biodiesel has certain advantages, such as a higher number of cetan, biodegradability, low sulfur content and aromatic content, and lower carbon monoxide emissions, unburned hydrocarbons and particulate matter. One of the main issues related to biodiesel and biodiesel blends is the high viscosity of the fuel. Among the biodiesel properties, density, viscosity and heating value affect engine performance and emission characteristics. The presented paper highlights the differences that occur in comparison to the classical fuels and the performances obtained when using biodiesel.

The phenomenon of soiling of heat exchange surfaces occurs in all types of combustion plants. The deposit of solids (combustion gases particles) worsens heat transfer by reducing combustion efficiency, increasing fuel consumption and pollution. Deposits are influenced by combustion temperature, gas flow rate, dimensions of solids drift by combustion gases as well as the composition of fuel mixtures used (eg inferior coal with flame retardant gas or tar fuel). In the present paper are presented techniques and methods adopted for the reduction of soiling of the heat exchange surfaces and the results obtained on high energy power plants (steam boilers).

The paper presents a method for studying mechanisms with deformable elements, based on overlapping the solid rigid motion over the elastic solid one, in order to identify the dynamic response of the system. Modeling was based on finite element method, so the cinematic elements were meshed in bar type finite elements and the degrees of freedom per node were settled according to the motion character (planar or spatial). A Lagrange formulation of the finite element was adopted for the deformable elements connected in multibody systems. In order to define the joints constraints, the conditions for compatibility between elements were defined using a Boolean constant matrix. Computer processed results were verified by an experimental model.

The paper presents the results of the experimental determinations of the resistance of the massive masonry elements from a patrimony building in the Oltenia Region, the masonry under the action of the environmental factors and the strong seismic movements occurring during their lifetime. Starting from the models of massive masonry behavior specific to the analyzed building type, the short compressive strength of the masonry elements from the analyzed building was determined experimentally. All the researches undertaken bring valuable data needed to predict the collapse of massive masonry buildings in national and world heritage.

The paper presents the analysis of water and heat transfer through walls being thermally insulated with vegetal materials. The analysis identifies the risk for condense accumulation in the outer layers of external walls of a common residential building located in the coldest climatic regions of Romania. Different wall structures and insulation thicknesses are systematically considered with statistical extreme temperature and humidity outdoor values. Results are useful in designing nZEB individual houses with green and sustainable technologies that also provide energy savings and indoor conditions for good comfort and health in these desired building concept.
