Abstract:
The rocking motion of the tanks is complex and not fully understood. Using model tanks that possess concentric rigid-doughnut-shaped bottom plates, this paper tries to clarify its fundamental mechanics through the analog of rocking motion of rigid bodies. Introducing an effective mass for the internal liquid for rocking motion enables the development of a dynamical system including the rocking-bulging interaction motion and the effective mass of liquid for the interaction motion. Since the base shear and uplift displacement observed during shaking tests match well with computed values, the proposed procedure can explain the mechanics of the rocking motion of the model tanks used herein.

Abstract:
A tuned mass rocking wall (TMRW) is a passive control device that combines the merits of a traditional tuned mass damper (TMD) and a traditional rocking wall (RW). TMRWs not only help avoid weak story failure of the host structure but can also be regarded as a largely tuned mass substructure in the building structure. Through the appropriate design of the frequency ratio, the host structure can dissipate much more energy under earthquake excitations. In this paper, the basic equations of motion for the mechanical model of an SDOF structure-rigid rocking wall are established, and the optimization formulas of frequency ratio and damping ratio of TMRW are derived. Through the dynamic elastoplastic analysis of a six-story TMRW-frame model, the applicability of the derived parameter optimization formulas and the effectiveness of the TMRW in seismic performance control are investigated. The results demonstrate that the TMRW can coordinate the uneven displacement angle between stories of the host structure. Additionally, the TMRW is found to possess the merit of reducing both the peak and root-mean-square (RMS) structural responses when subjected to different types of earthquake excitations.

Abstract:
Self-centering systems, such as base-rocking-wall systems, have been studied and demonstrated to be capable of achieving enhanced seismic-resisting performance. For these rocking-wall systems, unbonded post-tensioning strands and damage-permitted energy-dissipating fuses are usually implemented along the full height of the walls. Structural damage and residual deformation of main structures can be mitigated through deformation of the fuses which are replaceable after strong earthquakes. An innovative self-centering system referred to as a pendulum-type nontraditional tuned mass damper system is newly proposed in this paper, which can be deemed to be an inverted rocking system. Pendulum components can automatically return to their original position due to the effect of gravity, without any post-tensioning strands being required. Energy dissipators are only implemented between the bottom end of the pendulum component and the ground, and they can be easily fabricated and replaced. Both experimental and numerical studies have been carried out to examine seismic performance of the pendulum-type nontraditional tuned mass damper system, and it is found that satisfactory control of interstory drift and floor absolute acceleration can be achieved, while small movement space is required.

Abstract:
For vertical isolated structures with excessive vertical eccentricity for mass and vertical stiffness, horizontal-vertical-rocking response needs to be better understood for vertical isolated structures located in near-fault areas, where long-period velocity pulse can be produced. In this study, a seismic isolation system including quasizero stiffness (QZS) and vertical damper (VD) is used to control near-fault (NF) vertical earthquakes. The responses of horizontal-vertical-rocking coupling base-isolated structure including quasizero stiffness (QZS) and vertical damper (VD) subjected to NF horizontal and vertical ground motions are investigated. Nonlinear dynamic analyses are conducted to study the effects of essential parameters such as isolation system eccentricity, static equilibrium position, vertical isolation period, and vertical damping ratio on seismic responses of vertical isolated structure. It is found that increasing vertical period and damping ratio causes the vertical isolated structures to behave well in reducing rocking responses of structure. The effect of horizontal-vertical-rocking coupling on vertical seismic isolation efficiency is insignificant. The vertical seismic isolation remains effective as compared to the system supported on rubber bearings. The vertical damping can significantly control the vertical displacement and rocking moment.

The objective of this work was to evaluate the efficiencies of protein extration for attainment of proteins leaf concentrate cassava (Manihot esculenta Crantz), using seven methods of extration cited by authors CEREDA & VILPOUX (2003), CHAVES (1987), TUPINAMBÁ & VIEIRA (1979) and FASUYI & ALETOR (2005). The experiment was carried through in the dependences of the State University of the West of the Paraná campus Cascavel, in the laboratory of Sanitation of the course of Agricultural Engineering. The cassava leves had been harvested in third part of the plant with age of 12 months in a property of the city of Cascavel. For the protein extration dehydrated leves had been used, with rude protein texts in dry base of 36.55 % and humidity of 11.27%. Methods 1 and 2 cited by CEREDA & VILPOUX (2003), method 5 cited by CHAVES (1987), method 6 cited by TUPINAMBÁ & VIEIRA (1979) and method 7 of FASUYI & ALETOR (2005) had been the ones that had gotten greaters proteins texts in the concentrates, above of 50%. The biggest incomes of extration had been gotten by methods 2, 5, 6 and 7 with incomes of protein extration above of 35%. Methods 1, 2, 4 and 5 had been tested using two consecutive extrations similar to improve the losses of mass and to increase the extration income, however only occurred the reduction of the losses of mass in the process, not being then necessary the use of two phases of extration. Methods 1, 2, 4 and 5 had been compared, already applied with leves dehydrated, using cool leves. The cassava leves (Manihot esculenta Crantz) cool had been harvested in third part of the plant with age of 9 months with rude protein texts in dry base of 27.70% with 72% of humidity. It did not have difference in the extration incomes, being more advantageous to use dehydrated leves due to possess minors toxic factors and greater durability. Methods 2 and 5 had revealed alternative for attainment of cassava proteins leaf concentrates, due to extration easiness, and not to need equipment and materials that can increase the cost of protein extration, thus making possible one better exploitation of cassava leves.

O experimento foi realizado nas dependências da Universidade Estadual do Oeste do Paraná, campus de Cascavel, no Laboratório de Saneamento do curso de Engenharia Agrícola. As folhas de mandioca foram colhidas no terço superior da planta com idade de 12 meses em uma propriedade da cidade de Cascavel. Para a extração de proteínas utilizaram-se folhas desidratadas, com teores de proteína bruta em base seca de 36,55 % e umidade de 11,27%. Os métodos 1 e 2 descritos por CEREDA e VILPOUX (2003), o Método 5 descrito por CHAVES (1987), o Método 6 e descrito por TUPINAMBÁ e VIEIRA (1979) e o Método 7 descritos por FASUYI e ALETOR (2005) foram os que obtiveram maiores teores protéicos nos concentrados, acima de 50%. Os maiores rendimentos de extração foram obtidos pelos métodos 2 e 4, com rendimentos de extração de proteína acima de 35%. Foram testados os métodos 1, 2, 4 e 5, utilizando-se duas extrações consecutivas, a fim de melhorar as perdas de massa e aumentar o rendimento de extração, no entanto somente ocorreu a minimização das perdas de massa no processo, não sendo necessária a utilização de duas fases de extração. Foram comparados os métodos 1, 2, 4 e 5, já aplicados com folhas desidratadas, utilizando-se folhas frescas. As folhas de mandioca (Manihot esculenta Crantz) frescas foram colhidas no terço superior da planta com idade de 9 meses com teores de proteína bruta em base seca de 27,70% com 72% de umidade. Não houve diferença nos rendimentos de extração, sendo mais vantajoso utilizar folhas desidratadas, devido ao menor fator tóxico e maior durabilidade. Os métodos 2 e 5 mostraram-se alternativos para obtenção de concentrados protéicos de folhas de mandioca, devido à facilidade de extração e de não necessitarem de equipamentos e materiais que possam aumentar o custo de extração de proteínas, possibilitando assim um melhor reaproveitamento das folhas de mandioca.

Abstract:
Nanotecnologia é o conjunto de conhecimentos acumulados pelo homem que permite controlar a produção de estruturas com uma ou mais dimensões nanométricas. Desde seus primórdios na década de 70, a nanotecnologia tem estado em constante ascensão, encontrando uma diversidade enorme de aplicações, como por exemplo em medicina e na indústria optoeletrônica. Por consequência, a demanda por equipamentos tanto de preparo como de caracterização/controle tem crescido exponencialmente. O uso da radiação X no estudo de dispositivos nanoestruturados tem sido, em grande parte, possível gra- ças as fontes síncrotrons com feixes intensos. Mas a disponibilidade desses laboratórios de alta tecnologia está aquém da crescente demanda das pesquisas em nanotecnologia, as quais precisam de técnicas de análise estrutural rápidas e de fácil acesso para otimização e controle da produção de dispositivos nanoestruturados. Com foco nessa falta por técnicas de análise estrutural, esta dissertação tem como objetivo avaliar quais parâmetros básicos de nanodispositivos, com substratos monocristalinos, podem ser investigados por meio de técnicas de difração de raios X utilizando fontes compactas de radiação, bem como avaliar as limitações instrumentais.
X-ray radiation has provided a powerful tool for analyzing the structure of materials at atomic scale. While many are fascinated with the perspectives oered by advanced X-ray sources, the practical aspects of these perspectives in the actual and future scenery of nanotechnology needs to be discussed. Nanotechnology, i.e. the capacity of controlling matter at atomic-molecular scales and manufacturing structures with dimensions of a few tens of nanometers, has provided a constant challenge for structural analysis via X-ray techniques. The great diversity of materials and methods derived from nanotechnology is generating a huge demand for time of analysis, much beyond of that can be supplied by synchrotron facilities worldwide. In optimizing nanostructured materials and devices processing methods, fast and easy-access techniques to control and characterization are required. Microscopy and spectroscopy techniques are very important in this scenery, but they have intrinsic limitations that have justied the search for high-resolution techniques of structural analysis, such as those obtained by diraction of X-rays. The use of Xradiation in the study of nanostructured device has been possible by synchrotron sources due to the high intense beams. But the availability of these high tech laboratories falls short of the growing demand for nanotechnology research. In this context, this dissertation intend evaluate which basic parameters of nanodevices with single crystal substrates can be investigated by techniques of X-ray diraction using compact radiation sources as well how to evaluate the instrumental limitations .

Abstract:
Rocking-mass gyroscope consists of an assembly of four cantilever beams with a rigid mass attached to them in the middle subjected to base rotations. Due to the gyroscope effect, the beams undergo coupled flexural-torsional vibrations. The main goal of the research is to develop an accurate model of such a system and along this line a detailed mathematical modeling of the gyroscope is developed. The equations of motion clearly show the presence of the gyroscopic couplings in all cantilever beams. A computer simulation model in its most general form has been developed, to analyze the effectiveness of this type of gyroscope.

Abstract:
I offer the final word on time to György Ligeti:As a small child I once had a dream that I could not get to my cot, to my safe haven, because the whole room was filled with a dense confused tangle of fine filaments. It looked like the web I had seen silkworms fill their box with as they change into pupas. I was caught up in the immense web together with both living things and objects of various kinds—huge moths, a variety of beetles—which tried to get to the flickering flame of the candle in the room; enormous dirty pillows were suspended in this substance, their rotten stuffing hanging out through the slits in the torn covers. There were blobs of fresh mucus, balls of dry mucus, remnants of food all gone cold and other such revolting rubbish. Every time a beetle or a moth moved, the entire web started shaking so that the big, heavy pillows were swinging about, which, in turn, made the web rock harder. Sometimes the different kinds of movements reinforced one another and the shaking became so hard that the web tore in places and a few insects suddenly found themselves free. But their freedom was short-lived, they were soon caught up again in the rocking tangle of filaments, and their buzzing, loud at first, grew weaker and weaker. The succession of these sudden, unexpected events gradually brought about a change in the internal structure, in the texture of the web. In places knots formed, thickening into an almost solid mass, caverns opened up where shreds of the original web were floating about like gossamer. All these changes seemed like an irreversible process, never returning to earlier states again. An indescribable sadness hung over these shifting forms and structure, the hopelessness of passing time and the melancholy of unalterable past events. (Ligeti, from program notes to ...

Abstract:
Rock Against Racism was one of the most dynamic and innovative British social movements of the 1970s, bringing together music fans and left-wing activists in the struggle against the far-right National Front. This surprising alliance was forged by members of the Trotskyist International Socialists/Socialist Workers Party who had a long-standing interest in popular culture and championed punk as a form of working-class revolt. This attitude contrasted sharply with that of the significantly larger Communist Party of Great Britain, which tended to view mass culture as a development of American capitalism. Seeking to adopt the dominant social and cultural norms of the labour movement, communists were unable to relate to the subversive irreverence of punk. Rock Against Racism disappeared in the very early 1980s but acted as a template for future attempts to link music and politics.

Abstract:
This chapter addresses the numerical modeling of freestanding rigid blocks by means of a semi-discrete approach. The pure rocking motion of single rigid bodies can be easily studied with the differential equation of motion, which can be solved by numerical integration or by linearization. However, when we deal with sliding and jumping motion of rigid bodies, the mathematical formulation becomes quite complex. In order to overcome this complexity, a Semi-Discrete Model (SMD) is proposed for the study of rocking motion of rigid bodies, in which the rigid body is considered as a mass element supported by springs and dashpots, in the spirit of deformable contacts between rigid blocks. The SMD can detect separation and sliding of the body; however, initial base contacts do not change, keeping a relative continuity between the body and its base. Extensive numerical simulations have been carried out in order to validate the proposed approach.

Thoreau felt a deep affinity for Pinus strobus, Eastern white pine, the tallest tree east of the Rockies. He called it the emblem of his life. He loved its erect posture, how its whorled branches jutt almost horizontal to its ramrod straight trunk. The pine was a sign of nature’s vigor. The scent of pines was an elixir to him. He identified with the pine’s wild spirit. Nothing stands up more free from blame than a pine tree. White pines played a big role in American history. Sought for masts by England, they became an early symbol of American identity. The tallest pines are not gone. Researchers have found 17 white pines in Massachusetts at least 160 feet.

Full text
Abstract:
The basic climatic characteristics of the major mountain ranges in the United States—the Appalachians, the Coast Range, the Alaska Range, the Cascade Range, the Sierra Nevada, and the Rocky Mountains—can be described in terms of the four factors discussed in chapter 1. The mountains of North America extend latitudinally all the way from the Arctic Circle (66.5°N) to the tropic of Cancer (23.5°N) (figure 2.1). There are significant differences in day length and angle of solar radiation over this latitude belt that result in large seasonal and diurnal differences in the weather from north to south. Elevations in the contiguous United States extend from below sea level at Death Valley to over 14,000 ft (4270 m) in the Cascade Range, the Sierra Nevada, and the Rocky Mountains. Several prominent peaks along the Coast Range in Alaska and Canada (e.g., Mount St. Elias and Mount Logan) reach elevations above 18,000 ft (5486 m). Denali (20,320 ft or 6194 m) in the Alaska Range is the highest peak in North America. The highest peak in the Canadian Rockies is Mt. Robson, with an elevation of 12,972 ft (3954 m). The climates of the Coast Range, the Cascade Range, and the Sierra Nevada, all near the Pacific Ocean, are primarily maritime. The Appalachian Mountains of the eastern United States are subject to a maritime influence from the Atlantic Ocean and the Gulf of Mexico, but they are also affected by the prevailing westerly winds that bring continental climatic conditions. Only the climate of the Rocky Mountains, far from both the Pacific and Atlantic Oceans, is primarily continental. Each of the mountain ranges is influenced by regional circulations. For example, the Appalachians are exposed to the warm, moist winds brought northward by the Bermuda-Azores High and to the influence of the Gulf Stream. Similarly, the Coast Range feels the impact of the Pacific High, the Aleutian low, and the Japanese Current. A mountain range, depending on its size, shape, orientation, and location relative to air mass source regions, can itself affect the regional climate by acting as a barrier to regional flows.

Full text
Abstract:
In analyzing the rocking motion of the flat-bottom cylindrical tanks subjected to severe earthquakes, the effective mass of fluid for the rocking motion and its moment inertia around the pivoting bottom edge of the tank would be indispensable dynamical properties, because they couples the fluid-shell interaction motion, the so-called bulging motion, with the rocking motion. This paper quantifies them based on the equilibrium of the fluid pressure and inertia force accompanying the angular acceleration acting on the pivoting bottom edge of the tank. Employing a general mathematical solution for the fluid pressure that can calculate either fully or partially uplifted tank bottom, this paper presents mathematical formulae of the effective mass of fluid for the rocking motion and its moment inertia. These quantities are given by an explicit function of dimensional variables of the tank but with Fourier series. For designer’s convenience, the effective moment inertia and effective mass of fluid for the rocking motion and its center of gravity from the pivoting bottom edge are normalized accordingly and are depicted on diagrams.

Full text
Abstract:
In experimental and analytical studies of the rocking response of a circular cylindrical tank under the action of the purely horizontal and translational ground motion, the author analogically quantified the mass of fluid contributing to both bulging and rocking motion of the tank. It was called “the effective mass of fluid for the rocking-bulging interaction.” Its dynamical role in the rocking motion of the tank was thoroughly investigated. However, applying it to design process requires us to use its rigorous definition. To date, the fluid pressure on the tank induced by the impulsive (= bulging) motion and the rocking motion and their effective masses of fluid for each motion were mathematically defined, respectively. Therefore, this paper tries to define the effective mass of fluid for the rocking-bulging interaction based on the fluid pressure on the tank mathematically. The effective mass of fluid for the rocking-bulging interaction is understood as a part of the effective mass of fluid for the bulging motion that is also under the action of the rotational inertia. The influence of the rotational inertia on the effective mass of fluid for the bulging motion is measured by a ratio of the apparent density of fluid contributing to the rocking motion to the original density of fluid. The distribution of the apparent density of fluid contributing to the rocking-bulging interaction is drawn for the various aspects of tanks. The ratio of the effective mass of fluid for the rocking-bulging interaction to the total mass of fluid of the tank is given as the function of the aspect ratio of the tank and the ratio of the uplift width of the tank bottom.

Abstract:
Accurate and easy calculation of the mass of fluid contributing to the rocking motion of cylindrical tanks with partial uplift of bottom plate, which is the effective mass of fluid for rocking motion, that for rocking-bulging interaction, effective moment inertia of fluid for rocking motion and their centroid, is proposed. Asymmetric deformation of the tank bottom plate due to crescent-like uplift is used to put quantification of the masses away from rigorous treatments. This study considers the cylindrical tank as a set of thin rectangular tanks, so-called a slice model, and puts them perpendicular to the rotational axis of the tank rock motion. Then solve a boundary-value problem of each slice model specified by uplift of the tank bottom plate and its location, the mass of fluid contributing to rocking of cylindrical tanks is quantified as the sum of that of each slice model. Values of the effective mass of fluid for rocking motion, that for rocking-bulging interaction, effective moment inertia of fluid for rocking motion and their centroid are tabulated and depicted as a function of the aspect of tanks for different values of the ratio of the uplift width of the tank bottom plate to the diameter of tank.

Abstract:
Employing a few feasible physical quantities of liquid related to the rocking motion of tanks, this paper tries to understand the fundamental dynamics of the rocking motion of tanks. Introducing the effective mass of liquid for rocking motion and for rocking-bulging interaction motions, the equations of motion are derived by analogue of rocking motion between rigid bodies and tanks. Using the exclusive tanks that possess the rigid-doughnuts-shape bottom plate that guarantees the uplift region of the bottom plate and the extent of the effective mass of liquid for rocking motion, the harmonic shaking tests are carried out. The proposed procedures can stepwise trace the base shear and the uplift displacement of the model tanks used herein.

Abstract:
The mechanical analogy of the rock-translation interaction system of the tank is verified by comparing analytical results with experimental ones. To trace actual rocking behaviors of the tank, the existence of effective mass and moment inertia of liquid for a rocking motion, which is proportional to the uplift region of bottom plate, is assumed. The comparison of restoring moment defined by early investigators with overturning moment by proposed methods can identify the region of effective mass for a rocking motion in an iterative manner. Moreover, the base shear and uplift angle calculated agree with ones measured at previous shaking tests. These results corroborate the applicability of proposed methods. Finally, the sufficient friction to enter and sustain a rocking motion of the tank is discussed based on time histories of horizontal and vertical reaction forces on the pivoting edge.

Abstract:
The governing equations of motion of the walking phenomena of the unanchored flat-bottom cylindrical shell tanks are examined. This paper considers that the walking phenomena is followed by the rocking motion of the tanks, since the rocking motion induces the reduction of self-weight and consequently reduces friction force between the tank and the foundation. The equations of motion are derived through variational approach. The physical quantities related to the walking phenomena are the mass of tank itself, tank content, the effective mass of liquid for bulging motion, for rocking motion and for rocking-bulging interaction motion, and friction force including self-weight reduction effects. The roles of every physical quantity related to the walking motion are clearly identified. The time history of the walking motion of the model tank induced by the initial enforced uplift angle and then gently released is well computed by the proposed procedure.

Abstract:
In Japan, a number of three-dimensional base isolation systems have been studied for application to new nuclear plant concepts such as the FBR, but these efforts have not so far yielded practically applicable results. The impeding factor has been the difficulty of obtaining an adequate capacity on the vertical isolator for supporting the mass of an actual structure and for suppressing rocking motion. In this paper, we propose a new three-dimensional isolation system that should solve the foregoing problem. The system is constituted of a set of hydraulic load-carrying cylinders connected to accumulator units containing compressed gas, a set of rocking-suppression cylinders connected in series, and a laminated rubber bearing laid under each load-carrying cylinder. The present paper covers a basic examination for applying the proposed system to a FBR plant now under development in Japan. In order to verify expected system performance, the load-carrying cylinders were first tested independently of rocking-suppression cylinders, and this was followed by integrated dynamic test of the system incorporating both load-carrying and rocking suppression cylinders. Response analysis reflecting the test results has indicated the proposed system to be well applicable to the envisaged commercialized FBR. The study was undertaken as part of a research and development project sponsored by the government for realizing a three-dimensional seismic isolation system applicable to future FBR.

Abstract:
Due to the Hyogo-ken Nambu Earthquake in 1995 and the huge earthquakes which are considered to occur in near future, the raise in the seismic design criteria in the horizontal and vertical excitations has been investigated. According to these trends, many base isolation structures have been developed and constructed. However, the most of these structures are limited to the horizontal base isolation. Therefore, the development of the effective 3-dimentional base isolation system becomes more and more important. The conventional 3-dimentional base isolation systems proposed up to now are insufficient in reducing the vertical natural frequency, otherwise are very complex due to facilitation of the active components. In this study, the dynamic characteristics of a high performance 3-dimentional base isolation system newly developed by the authors are reported. This system employs a velocity reduction system using a gear mechanics which can reduce the vertical natural frequency less than 1Hz while that of the conventional system is around 3Hz. And also this employs friction dampers to suppress the large displacement. Further, this system is facilitated with a rocking-suppression system which can effectively suppress the rocking motion inevitable for 3-dimentional base isolation. The response acceleration, displacement and rocking motion are evaluated by numerical simulations in varying the friction force, the predominant frequency of seismic input waves, the eccentricity of the upper structural mass, etc.. As the results, it is shown that the base isolation system developed here has very effective base isolation characteristics and the rocking suppression effects. And the optimization of the structural parameters is also discussed.
