The Premiere-Chute hydroelectric power station, commissioned in 1968, has four hydraulic turbines for a total of 130 MW. One of the pilasters of the dam weir, built with pre-stressed concrete, showed a crack at the level of the post-tension cable. This paper presented an evaluation of the behaviour of the pilaster in question, No. 9. The main goal was to prevent any disruption to the gate opening through adequate monitoring for a long term data follow-up. Six long-base OSMOS type optical sensors were installed on each face of the spillway pilaster. The behaviour of the No. 9 pilaster was then compared with that of other pilasters with respect to the effects of temperature and water level fluctuation in the dam. After the pilasters had been monitored for six months, it was found that No. 9 pilaster showed the least deformation of all. It was therefore concluded that the behaviour of this pilaster was normal.

The proximal femoral morphology of fossil hominins is routinely interpreted in terms of muscular topography and associated locomotor modes. However, the detailed correspondence between hard and soft tissue structures in the proximal femoral region of extant great apes is relatively unknown, because dissection protocols typically do not comprise in-depth osteological descriptions. Here, we use computed tomography and virtopsy (virtual dissection) for non-invasive examination of the femoropelvic musculoskeletal anatomy in Pan troglodytes, P. paniscus, Gorilla gorilla, Pongo pygmaeus, and Homo sapiens. Specifically, we analyze the topographic relationship between muscle attachment sites and surface structures of the proximal femoral shaft such as the lateral spiral pilaster. Our results show that the origin of the vastus lateralis muscle is anterior to the insertion of gluteus maximus in all examined great ape specimens and humans. In gorillas and orangutans, the insertion of gluteus maximus is on the inferior (anterolateral) side of the lateral spiral pilaster. In chimpanzees, however, the maximus insertion is on its superior (posteromedial) side, similar to the situation in modern humans. These findings support the hypothesis that chimpanzees and humans exhibit a shared-derived musculoskeletal topography of the proximal femoral region, irrespective of their different locomotor modes, whereas gorillas and orangutans represent the primitive condition. Caution is thus warranted when inferring locomotor behavior from the surface topography of the proximal femur of fossil hominins, as the morphology of this region may contain a strong phyletic signal that tends to blur locomotor adaptation.

The gill of fish is not only the respiratory organ, but also the absorptive and excretory one of various substances, such as pesticides, anesthetics and minerals including radionuclides. Branchial absorption of Ca, Cr, Zn, Sr and Hg, and dieldrin (a pesticide) has been demonstrated by the gill-perfusion experiments using eel and rainbow trout. Also, branchial excretion of Cl, Ca and Sr has been ascertained by the same method using eel. Therefore, the gill is an important organ in relation to the accumulation and metabolism of radionuclides in fishes. Compared with the kidney, another excretory organ in fish, the structure of fish gill is rather simple. Histologically, the gill lamella, main functional portion of gill, is enveloped with simple squamous epithelium on each side. Between these two thin layers, pilaster cells and lacuna of branchial capillary are recognized as tissue components. In the gills of marine fishes, well-developed salt-secreting cells are detectable at the basal area of gill lamella. The cytoplasm of these cells are acidophilic and abundant in mitochondria and tubular endoplasmic reticulum. The cells are also called chloride cells and said to be involved in the extra-renal excretion of Na and Cl took in by marine fishes. The important problem is whether the salt-secreting cells in marine fishes are also concerned with the branchial excretion of another minerals such as Ca, Sr, I and so on, or these minerals are excreted across the ordinal epithelial cells of gill lamella. To elucidate this, detailed investigatios are awaited with interest. (author)
Full Text Available The wall painting on the façades of St. Nicholas in Ljuboten near Skopje, the endowment of 'Lady Danica', a noblewoman in the time of King Dušan, was destroyed in 1928, during the restoration of the church. Evidence of the appearance of the hitherto unnoticed decoration on the western facade and the southern entrance can be seen on glass plates in the Photograph Collection of the National Museum in Belgrade. When the photographs Nos. 1438, 1444 and 1567 were taken, the painting on the Ljuboten church façades, although damaged or washed away, was still partly visible. On the western façade it extended in three zones (the socle, the standing figures and the busts across the entire façade and from the ground to the porch, the roof of which stood at the foot of the western wall archivolt, while the ornamentation of the southern façade covered the lunette above the entrance and its archivolt. Although in 1925, the painting did not contain a single legible signature or physiognomy, thematically, the outer ornamentation of Ljuboten is essentially clear. The bust of the Mother of God with the infant Christ, facing south, was in the centre of the compositional focus of the western façade. Three figures stood on the left and on the right sides of the portal, one on each of the pilasters, and one monumental figure in each of two niches. From the south, a church hierarch, with short, curly beard, was moving in a stooping position towards the Mother of God. He, certainly, could be identified as the patron of the church, St. Nicholas. The saint raises his right hand in a gesture of exhortation. Behind him, a figure in monastic habit was painted. This person holds a model of the church in the left hand, with the right hand in a gesture of prayer. Undoubtedly, it was the donatrix of the church painted here. As opposed to the figures in the southern part of the western façade, those in the northern part were facing forward. We recognized a saint on the

Church is one nave with a semicircular apse at the east vaults with semicircular arch reinforced with cross section curve, which relies on a few strong pilasters placed inside long walls. According to folk tradition the church was built in the middle ages and served to diggers and foundries of lead ores of King Milutin. Upon termination of exploitation ore the church neglected and in the 19th century it suffered its first renewal 1871st and another 1895th year. Saved epigraphic inscription with carved year of renewal (1895th, icons and wall decor of the church provide information about reliably judging its recent history and artistic value. Soon after the bricklaying work 1895th Church has received from the altar wall of icons, and after that, and mural painting small artistic value. The crown of the vault is painted Pantocrator, about whose performances are painted scenes of the Transfiguration, Ascension of Christ, Vavedenje and Entry into Jerusalem. On the western wall are shown the Dormition of the Mother of God and in the first zone are shown standing figures of Sts. Constantine and Helena, St. Simon Mir refills and St. Prince Lazar - kefaloforos. On the triumphal arch are Old. Testament scenes of hospitality and sacrifice of Abraham and in the apse bust of God Savaot. In the zone of standing figures are shown Sts.

Full Text Available In recent years, engineers and architects in our country have been prompted to rethink the design and construction of brick masonry enclosures on portal frame structures due to the pathologies that frequently appear these walls, and in response to the need for a new technology that would minimize the existing problems.
Together with damp, cracking is the most common pathological process affecting today’s brick masonry enclosures and may be caused by a number of factors (Figure A. But according to ASEMAS, the Spanish architects’ mutual association, in all cases cracking is ultimately the result of low tensile strength.
The brick masonry walls built today rest on and cantilever out from slab edges, resisting wind action as a result of vertical arching between consecutive slabs, which leads to an inevitable accumulation of loads on the enclosure.
Cracking can be controlled, firstly, by reinforcing the wall to enhance ductility, but this calls for horizontal movement joints on the under side of the slabs to avoid the accumulation of loads on the enclosures, a solution that nonetheless weakens the wind strength of the panels.
AllWall has been devised to eliminate the need for anchorage pilasters behind walls, which block the air chamber and create insulation gaps. This new system consists in a series of inventions related to masonry and reinforcement typology that enable masons to erect threeway reinforced panels using mortar instead of concrete.
These inventions have paved the way for the development of new brick facade typologies - supported, suspended or prefabricated - whose continuous air chambers, free of damp and thermal bridges, guarantee the hygrothermal efficiency of the enclosure.
Currently implemented in any number of buildings in our country, the technology presents advantages that make it apt for any other area, including regions where seismic risk is high.

, facing east, flanked by rectangular choirs. The interior of the church, with two pairs of small pilasters, was articulated in three bays of almost equal dimensions. The altar, encompassing the apsis and the eastern bay, was separated from the naos by a constructed altar partition-wall, the essential appearance of which can be assumed on the basis of whatever was found. The entire surface of the constructed iconostasis was covered with frescoes. The floor of the naos was a step lower than the floor of the altar. Flooring made of mortar, like in the altar area also existed in the choirs. As opposed to these spaces, in the central and western bays, the floor was made of large, hewn stone slabs. The finds discovered in the debris, offered an abundance of data about the upper, now collapsed, structures of the church, and about the stonemasonry that decorated this building. The church did not have a dome but all three bays were topped by a single vault of carved calcareous stone, reinforced by two arches, resting on the pilasters. We may assume that the roof structure was of the Gothic type, and ribbed at the base. Above the choirs were lower semi-spherical vaults, perpendicular in relation to the longitudinal axis of the church. They were covered by gabled roofs that ended in triangular frontons on the northern and southern façade, like the main vault on the eastern side above the altar apsis. The roof of the church was made of lead. A belfry, of unique construction, existed on the western side of the original church. It stood about one meter in front of the western wall and was linked by a vaulted passage to the main body of the building. All these parts were structurally inter-connected, indicating that they were built at the same time. The position and appearance of the original church windows can almost certainly be determined according to the preserved traces on the remaining sections of the walls, and the finds of the relevant stonemasonry. In the interior of the naos

In 2008, the remains of an earlier building were discovered beneath the floor of the apodyterium of Galerius' bath found in 2002 and below the foundation of the sudatorium and the tepidarium of the same structure, which were found in 2005. Also, for the purposes of conservation and restoration of the thermae, an apsidal room next to the west wall of the apodyterium, so called 'Galerius' dressing room', was completely filled with construction rubble, among which was found a part of an abraded vault (Fig. 6. Excavations proved that the apsidal room had been a pool with cold water, a frigidarium, which was twice renovated and was decorated with mosaic made of black, white and grey stone cubes (Fig. 7. The phases of reconstruction of the frigidarium could also be noticed in its eastern wall (Fig. 8. Also in the rubble inside the pool, glass mosaic cubes of deep blue and golden colours were discovered, indicating the decoration of the vault. In the latest phase, two pillars were constructed to carry the stairs made of stone slabs (Fig. 8. The earliest phase of this room, which had a rectangular layout and a mortar floor, could be part of the building dating back to before Galerius' bath (Plan 2. During the cleaning of the eastern wall of the frigidarium, a semicircular niche with a fresco decoration of geometrical and figural motives, painted in black, dark red, orange and blue on an ochre surface, was discovered (Fig. 3. Under Galerius' bath, a large earlier building was investigated (trenches 1-5/08. Only its foundation zone is preserved. The walls of the Imperial bath were founded on the earlier walls, which were 0.65 m thick and had foundations which were 0.90 m thick (Plan 2. The pilaster of the west faeade of the thermae was also founded on the earlier wall, but it destroyed a water canal
