Abstract The researched truss of the Gothic Church of St. Bartholomew in the village of Mladočov is one of the examples of the use of the historical Czech length units of measurement; in this case, the Gothic and Baroque part of it. At the same time, it analyzes the proportional relationships between the individual elements of the truss. The structural analysis in relation to current standards points to the fact that the original design of the structure based on geometrical and proportional principles satisfy the reliability conditions defined by current European standards for structural design.

The Impact

Abstract In this paper, an evaluation was tried for the impact of structural design on structural response. Several situations are foreseen as the possibilities of changing the distribution of the structural elements (sails, columns, etc.), the width of the structure and the number of floors indicates the adapted type of bracing for a given structure by referring only to its Geometric dimensions. This was done by studying the effect of the technical design of the building on the natural frequency of the structure with the study of the influence of the distribution of the structural elements on the seismic response of the building, taking into account of the requirements of the Moroccan earthquake regulations 2000/2011 and using the ANSYS APDL and Robot Structural Analysis software.

Speed Performance

A surface effect ship is known to be comparable to a high-speed ship. For the structural design of surface effect ships, advanced design methods are needed which can reflect the various loading conditions different from those of conventional ships. Also, minimum weight design is essential because hull weight significantly affects the lift, thrust powering and high-speed performance. This paper presents the procedure of optimum structural design and a computer program to minimize the hull weight of surface effect ships built of composite materials. By using the developed computer program, the optimum structural designs for three types of surface effect ships—built of sandwich plate only, stiffened single skin plate only, and both plates—are carried out and the efficiency of each type is investigated in terms of weight. The computer program, developed herein, successfully reduced the hull weight of surface effect ships by 15–30% compared with the original design. Numerical results of optimum structural designs are presented and discussed.

Current Standards

Flashing yellow warning lights notify drivers about the presence of work along the road. Current standards for these lights address performance of the individual light but not how lights should function when multiple lights are used. In the present study, warning lights were used to delineate a lane change taper in a simulated work zone. Lights flashed with varying intensities and either randomly or in sequence, with lights flashing in turn along the length of the lane change taper, either to the right or to the left. In half of the trials, a flashing police light bar was used on a vehicle located within the simulated work zone. Participants were asked to drive a vehicle approaching the work zone and to identify, as quickly as possible, in which direction the taper’s lane change was (either to the right or left). Drivers were able to correctly identify the taper from farther away when the lights flashed in a sequential pattern than when the flash pattern was random; and the presence of a police light bar resulted in shorter identification distances. The results, along with previous research, can inform standards for the use of flashing lights and police lights in work zones for the safety of drivers and workers.

Structural analyses of mechanisms with components that move relative to each other provide a unique problem to the analyst building and running structural models. In these situations, the analyst usually has to either simplify the problem to a point where the results are unusable or maintain multiple models, which will take more effort to maintain and more resources to run the models. If a mechanism is simplified down to just analyzing one component at a time without regard for the other components in the system, the results will not be accurate because the loading effects of the other components will not be accounted for. In cases where all the components are included in the model the loading effects from the other components will be accounted for, however, a separate model will be required for each position. This paper presents a method of breaking down the complex mechanism into a component level model for each part of the assembly, while still accounting for all loading effects of the other components; in the Pivot Method the component under analysis stays stationary and the loading moves around the component to represent the different positions that it can take. In order to accomplish this task, a simplified model is used to generate loads at each of the joints. Once the pivot loads are known, a spreadsheet can be used to transform the loads to a coordinate system in which the individual component is being modeled. With the pivot loads known and all the loads transformed into the proper coordinate system the structural analysis of the component under investigation can continue. The intention of this paper is to introduce the Pivot Method and to demonstrate that it provides a good trade off between both the complexity of methods that model the assembly as a system, and those that focus on the component under question alone. To accomplish this, the analysis results of the Pivot Method models will be compared to results obtained from other methods, with the intention of showing that the Pivot Method will provide the same results while requiring less effort to model and less resources to run.

PROJEMAR S. A., a naval and offshore design company at Brasil has developed several conversion projects of FPSO’s to operate at Campos Basin. This way, PROJEMAR faced some interface difficulty in the structural design of the topside supports, mainly for the vessel reinforcement. The structural analysis of the cargo region, when performed together with the topside supports and loads, introduces significant buckling and fatigue problems in the main transverse and longitudinal structure of the vessel. The solution adopted in first instance is to reinforce the transverse structure and longitudinal bulkheads of the cargo tanks just below the topside supports. This reinforcement is expensive and takes a lot of time to be done, as hundreds of buckling bars should be installed. In order to avoid this work inside the cargo region, PROJEMAR evaluated this study to minimize the steelwork inside the cargo region, and to optimize the steel weight for topside supports. PROJEMAR analyzed three different concepts of topside supports: two transverse bulkheads supporting each topside module, two sets of strong brackets supporting each topside module, and sets of pillars supporting each topside modules. The results present the amount of steelwork inside and outside the cargo tanks, the total amount of steel reinforcement after the evaluation of stress, deflection, buckling and fatigue verification. The conclusions present cost and benefit for each solution, and some discussions on the time acceleration for the conversion.

There is a common belief that medieval men and women lived their lives within a narrow geographical and psychological space, the village and the neighboring fields for the most part. According to this opinion, it was not until the Renaissance and the voyages of Columbus and those who followed him that Europeans became aware of the wider world around them and shed the blinders that had constrained them for centuries. What makes this opinion so at odds with medieval reality is that one of the most famous and widely read pieces of medieval literature, Chaucer’s Canterbury Tales, deals with the travels of a group of medieval Christians who range from a crusading knight to farm laborers, individuals representing a cross section of the middling levels of 14th-century English society. Merchants, crusaders, missionaries, pilgrims, exiles, and others motivated by simple restless curiosity traveled around Europe, to the edges of the Christian world, and then all the way to China and India and, sailing westward, to North America. Travel and travel imagery also played an important role in Christian life. The Bible begins with the creation of the world, traces the course of God’s involvement with his people over time, and concludes with the end of the world, the ultimate goal of mankind as defined by the Creator. The life of the individual Christian is a pilgrimage within this context, the movement of the soul to union with God, a microcosm of this larger narrative. It is no coincidence that the most famous work of medieval literature, Dante’s Divine Comedy, was cast as a travel tale.

Mouse Teratocarcinoma

Pronase digests of cultured teratocarcinoma-derived cells (PA 1) of human origin have been previously shown to contain large-sized glycopeptides (relative mass (Mr) > 7400), of which 15–23% are retained by columns of concanavalin A (Con A) – Sepharose and can be eluted with 10 mM methyl α-D-mannopyranoside. The present data show that this fraction (A – Con A II) contains a family of glycopeptides that are degradable with anhydrous hydrazine as well as with 0.05 M NaOH – 1 M NaBH4. The cleavage products representing individual oligosaccharide chains, presumably as oligosaccharides and glycopeptides, consisted mostly of medium- (Mr 1400–6000) and small-sized (Mr < 1400) molecules. This implies that glycopeptides bearing several oligosaccharide chains were present in A – Con A II. Most of the individual oligosaccharide chains were not bound to Con A – Sepharose, but some were retained by the lectin column in the same way as the original glycopeptides. Some of the oligosaccharides were degraded partially with endo-β-galactosidase from Escherichia freundii suggesting the presence of GalβGlcNAcβ repeats. The present findings show that A – Con A II may be different from the "embryonic" glycopeptides of mouse teratocarcinoma cells that are reportedly not cleaved by mild alkaline borohydride treatment. Instead, A – Con A II is reminiscent of the T-1 glycopeptide of glycophorin.

The Church

The parochial priests in small Paraguayan towns are generally reputed, in Paraguay, to exercise an extraordinary amount of power and influence over the people of their parishes—to a greater extent, it would seem, than in most other Latin American countries. This is, moreover, despite the fact that the church, as an institution, is considerably weaker, economically and politically, than in all but a handful of such countries. Therefore, what power the individual priest may have can not be viewed as simply an extension of the power of the church. Most urban Paraguayans, including at least some members of the church hierarchy, are inclined to attribute this situation to the alleged superstitious or credulous nature of the Paraguayan peasants. The rural people themselves, on the other hand, are apt to explain the influence of their own local priest, at least, as due to his personal qualities or strength of character, as did the Services when referring to the prestige of the local priest of Tobati.

In recent years, the traditional motifs and conceptual approach to the apparent authenticity of the design quality is observed that used in many areas. In this way, the tradition established in the future synthesis has led to the formation of a free and original design. This synthesis, design resources training in the artistic development of the individual and provide the best research and questioning the reasons that created them.Thus; new ideas to new situations, new problems have emerged in the need to turn to different events and phenomena. This method and the proliferation of studies aimed at the promotion of Turkish cultural heritage is undoubtedly will be at the forefront of higher quality products.The suggestions of ‘interpreting the traditional designs’ and the comprehension of what is ‘traditional’, which are proposed by some academics and designers are evaluated with a critical approach. The subject is examined within the frame of traditionalist suggestions offered from the time of the Ottomans till today, with the conceptions of the Western science, culture, art and design developed through the period of the Industrial Revolution.
