This declaration ponders the impacts of Joule warm, separation, and warming radiation for the progression of MHD Sutterby nanofluid past over an all-inclusive chamber. The wonder of warmth and mass conduction is demonstrated under warm conductivity relying upon temperature and dispersion coefficients individually. Besides, the conventional Fourier and Fick laws have been applied in the outflows of warm and mass transport. The control model comprising of a progression of coupled incomplete differential conditions is changed over into a standard arrangement (...) of nonlinear coupled differential conditions by reasonable likeness changes. The subsequent arrangement of articulations is systematically treated through an ideal homotopic method. The impacts of various dimensionless stream boundaries on the speed, temperature, and focus fields are delineated through diagrams. The range of some parameters involved is assumed for the convergent solution as 0 < R e < 10, 0 < P r < 6.5, 0 < E c < 40, 0 < R d < 1.5, 0 < S 1 < 0.5, 0 < S 2 < 0.5, 0 < L e < 0.5, 0 < N t < 2.5, and 0 < N b < 2.0. The patterns of skin friction coefficient, local Nusselt, and Sherwood numbers are examined via bar charts. The principle consequence of the proposed study is that the decay of the speed for the Sutterby liquid boundary, the deterioration of the variable warm conductivity, the temperature, and the radiation increase the framework temperature. The delineation boundaries show the opposite conduct for the temperature and fixation outskirts layers. (shrink)

The focus of the paper is the comparison between the two composite aluminum panels, respectively Alpolic and Durabond. The paper is going to explore their reaction when interacting with Tirana`s climatological factors and their tension strength through an experiment, in order to find out which panel displays the best performance. The construction urge is constantly evolving, especially in Tirana mostly because it is the main industrial and economical district of Albania. It is distinguished that innovative technology is being used in (...) facades of the new buildings. One of the features that finds massive use in façade coating in the city is the application of ventilated facades equipped with external aluminum composite panels. This paper is going to deal with two buildings with different typologies of external coating, including the different types of aluminum panels. The analysis will focus on identifying each panel property such as tension strength; their respond to various external factors; their thermal conductivity; and their manufacturing companies which have been selected and produced. Within this paper graphics displays of the records will be included, offering concentrated information and a high level of reliability for both aluminum composite panels. (shrink)

The aim of this paper is to verify whether step aerobics training has an impact on the temperature of deep muscles of the spine of young, healthy subjects and if there exists a relationship between the maximal oxygen uptake and thermal results. The study was conducted in a group of 21 subjects of both sexes, aged 20.2 ± 0.38. The step aerobics training sessions lasted 30 weeks, one training session per week, 60 minutes per session. Thermograms of the spine (...) were taken with the use of an infrared thermographic camera. Instrumental measurements included BMI, vital capacity of the lungs, and maximal oxygen uptake. After a 30-weeklong SAT, a statistically significant increase in the average temperature of the muscles of the thoracic and lumbar spine was observed in subjects of both sexes. The relationship between VO2max and temperature of the muscles of the thoracic and lumbar spine after the 30th SAT was not statistically significant. The study showed that a 30-weeklong step aerobics training had a positive impact on thermoregulation of apparently healthy male and female subjects aged 20. Furthermore, it can be safely assumed that thermography may be used as a non-invasive method of examination of the thermoregulation mechanism of SAT participants. (shrink)

Extruded polystyrene (XPS) otherwise known as a thermoplastic polymer has a closed cell structure and is often stronger, with a higher mechanical performance. XPS is a pressed material and is sold in different thicknesses ranging from 2 cm to 10 cm, thus having a weight that varies from 28 to 45 kg/m3 due to the force and pressure exerted on it. In general, XPS material has very low thermal conductivity and is resistant to bending. This material obtains typical values (...) of thermal conductivity between 0.025 and 0.040 W/m∙K., which means that it is ideal for surfaces that have to withstand weight, continuous traffic, etc. It is also resistant to moisture absorption and has a homogeneous density. Other characteristics of the material are good acoustic properties, easy assembly, and high durability over time. It should always be kept in mind that the surface where the thermal insulation will be applied must be leveled, cleaned, and dried. Primer is applied, before placing the thermal insulation on the surface. Then, XPS boards are placed on the surface, adhering to the corresponding mortar. This paper will deal with different cases of application of XPS tiles in the city of Tirana. A closer look at the resistance of this material from the day of application until today will be analyzed. The results during the observations showed high thermal stability of the material and no mold surface. EPS Expanded Polystyrene, otherwise known by the Dow Chemical trademark name STYROFOAM, is a lightweight product made from expanded plastic beads. It was first discovered by Eduard Simon in 1839 in Germany. EPS in its composition has 95% air and only about 5% plastic. This material is used because of its excellent properties, including good thermal insulation, good protective properties, and extremely lightweight. EPS is inert in nature and therefore does not result in any chemical reaction. EPS is durable, strong, and lightweight and can be used as an insulated panel system for facades, walls, roofs, and floors, as floating material in marine construction, and as a lightweight filler in road and railway construction. Different examples from the city of Tirana, of buildings where XPS and EPS materials are applied, are going to be analyzed, drawing conclusions. (shrink)

The increasing global demand for energy necessitates devoted attention to the formulation and exploration of mechanisms of thermal heat exchangers to explore and save heat energy. Thus, innovative thermal transport fluids require to boost thermal conductivity and heat flow features to upsurge convection heat rate, and nanofluids have been effectively employed as standard heat transfer fluids. With such intention, herein, we formulated and developed the constitutive flow laws by utilizing the Rossland diffusion approximation and Stephen’s law along (...) with the MHD effect. The mathematical formulation is based on boundary layer theory pioneered by Prandtl. Governing nonlinear partial differential flow equations are changed to ODEs via the implementation of the similarity variables. A well-known computational algorithm BVPh2 has been utilized for the solution of the nonlinear system of ODEs. The consequence of innumerable physical parameters on flow field, thermal distribution, and solutal field, such as magnetic field, Lewis number, velocity parameter, Prandtl number, drag force, Nusselt number, and Sherwood number, is plotted via graphs. Finally, numerical consequences are compared with the homotopic solution as a limiting case, and an exceptional agreement is found. (shrink)
