Determining the aeration efficiency of the stepped spillways is important because the Dissolved Oxygen (DO) concentration helps indicate the water quality. This study investigated the effects of varying step shape and chute slope on the aeration efficiency for stepped spillways. The measured parameters were DO, the inception point of the free surface, and the water surface profile above the crest to evaluate the geometry variation impacts. Several experiments were conducted on a six-step configuration over a stepped spillway with chute angle (θ = 26.6°, 21.8°, and 8.9°). The discharges up to 0.055 m3/s. The step configurations were including flat step, normal end sill, and quarter circle end sill. The results showed when the chute angle changed from 26.6° to 8.9°, the aeration efficiency of E20 improved with 11.51% at the lowest discharge and 6.05% at the highest discharge for the flat step model with 10 steps. Also, E20 improved 11.39% at the lowest discharge and 6.50% at the highest discharge for the flat step model with 6 steps. The performance of the steps with the quarter circle end sill model in terms of aeration efficiency increased by 10%.

Abstract Dissolved oxygen is essential to healthy streams and lakes. The dissolved oxygen level is an indication of how polluted the water is and how well the water can support aquatic plant and animal life. A higher dissolved oxygen level indicates better water quality. There is a significant oxygen transfer associated with most hydraulic structures because the air entrained into the flow is split into small bubbles, which greatly increases the surface area for transfer. Stepped chutes are a particular instance of this, and the aeration efficiency of such structures has not been studied in the laboratory and field. In this paper, the aeration performance of the stepped chutes with and without end sill was investigated in a large laboratory stepped chute. An empirical correlation predicting the oxygen transfer efficiency was developed for stepped chutes. The results indicated that l/h and s/h had a significant effect on the aeration efficiency of stepped chutes.

Recently, the usage of stepped spillways, as energy dissipaters, has increased and led to a reduction in the size of the stilling basin. Extensive experimental considerations, plus the high cost and extended time required for laboratory methods, are among the major issues that require precise attention to determine optimal step design. This research deals with comparing the 2-D numerical simulation and experimental description in stepped spillways equipped with inclined steps and end sill together and presents a brisk, reliable, low-cost, and non-experimental approach to designing the steps. In this new type and complicated geometry, simulation is more complicated than horizontal steps, because it needs more accuracy around the end sills. The VOF Method and the k-ε standard turbulence model are proposed to simulate the flow pattern and evaluate the energy loss over stepped spillway. Energy dissipations obtained through the numerical approach have been compared with laboratory measurements and demonstrate reasonable agreement. Also, the flow pattern, velocity vectors and flow direction resulted from numerical simulation is in a good agreement with the experimental results.

ABSTRACTFluid dynamic modelling of crystallising calc-alkalic magma bodies has predicted that differentiated liquids will ascend as boundary layers and that accumulation of these buoyant liquids near chamber roofs will result in compositionally stratified magma chambers. This paper reports physical features in La Gloria Pluton that can be interpreted as trapped ascending differentiated liquids. Leucogranitic layers decimetres thick, which are locally stratified, are trapped beneath overhanging wall contacts. The same felsic magmas were also preserved where they were injected into the wall rocks as dykes and as large sill complexes. These rocks do not represent differentiated magmas produced by crystallisation along the exposed walls because the felsic layers occur at the wall rock contact, not inboard of it. Rather, we speculate that evolved felsic liquids are generated by crystallisation all across the deep levels of chambers and that initial melt segregation occurs by flowage of melt into tension fractures. Melt bodies so formed may be large enough to have significant ascent velocities as diapirs and/or dykes. The other way in which the leucogranite occurrence is at variance with the convective fractionation model is that the ascending liquids did not feed a highly differentiated cap to the chamber, as the composition at the roof, although the most felsic in this vertically and concentrically zoned pluton, is considerably more mafic than the trapped leucogranitic liquids. This suggests that these evolved liquids were usually mixed back into the main body of the chamber. Backmixing may be general in continental-margin calc-alkalic magmatic systems, which, in contrast to those in intracontinental settings, rarely produce volcanic rocks more silicic than rhyodacite. That the highly differentiated liquids are preserved at all at La Gloria is a result of the unusual stepped nature of the contact and the entirely passive mode of emplacement of the pluton, which, in contrast to ballooning in place, does not result in wall zones being “scoured”.

A spillway is one of the most important parts of a dam for controlling floods. Among different types of spillways, stepped spillways are one of the best energy dissipaters. Due to technological advances and the satisfaction of two elements for safe and low-cost construction, the use of stepped spillways has increased widely. Due to this, more studies are focused on stepped spillways. Researchers have made some efforts and proposed different methods to improve structural efficiency to dissipate energy. Modifications on step geometry, regarding flow regime type, are one of these efforts. Flow pressure and its fluctuations on the steps of the stepped spillways is one of the main factors affecting structural design and safety. In this experimental research, reverse inclined steps combined with the end sills have been applied in four degrees [0o (horizontal), 5o, 8o, and 11o] to obtain static pressure in both the nappe flow and skimming flow regimes of stepped spillways. Static pressure obtained from reverse inclined steps with end sills have been compared to the amount in the horizontal step. Results indicate a slight increase in the energy loss rate when reverse inclined steps have been applied in the nappe flow regime of stepped spillways.

When was silk first brought across the steppe from far China towards the European world? There is silk from the Middle Bronze Age of Uzbekistan, in Scythian burials of Siberia and among the Hallstatt grave-goods of western Europe. Teasing out the story of silk depends on identifying the textile, and distinguishing its several varieties apart.

A hydroxyapatite (HAP)/silk fibroin (SF) bone-like biomaterial was fabricated through a coprecipitation process using stepped temperatures. We evaluated the effect of increasing temperatures on hydroxyapatite crystal arrangement on a silk fibroin surface. We found that the HAP crystal particles self-assembled on the silk fibroin surface. Further we found that with rising temperature the HAP crystal c-axis became progressively more parallel to the long axis of the silk fibroin. This deposition pattern is similar to that seen with HAP and collagen assembly in normal bone. Based on the XRD, SEM, and TEM results, we conclude that higher temperatures promote crystal nucleation resulting in an increase in both HAP crystal size and HAP/SF particle size. These data support the use of HAP/SF bone-like biomaterials for bone replacement and regeneration.

Vertedouros em degraus têm se tornado uma boa opção em barragens pela facilidade de construção e, principalmente, por apresentar uma dissipação significativa de energia ao longo de sua calha, o que faz com que a parcela de energia a ser dissipada por ressalto hidráulico a jusante da barragem diminua, ocasionando uma significativa redução nas dimensões da estrutura da bacia de dissipação. A aplicação de soleira terminal em bacias de dissipação provoca uma melhor distribuição das velocidades e um melhor comportamento da flutuação de pressões ao longo da bacia e a jusante, aumentando assim seu desempenho na dissipação de energia. A combinação destas duas formas de dissipação (vertedouro em degraus e bacia de dissipação com soleira terminal) pode ser utilizada como uma solução econômica e segura, entretanto, o dimensionamento dessas estruturas esbarra na falta de critérios e informações, principalmente quanto ao tamanho e posição ideal para o projeto de uma soleira terminal. No presente trabalho foram analisados os dados de pressões médias e flutuações de pressões no interior da bacia e a jusante da soleira terminal, sendo apresentadas metodologias para dimensionamento de tamanho e para posicionamento de uma soleira em função do número de Froude da entrada do ressalto hidráulico. Também está sendo apresentada uma metodologia para análise das pressões médias em bacia do tipo I (sem soleira), além de uma comparação do comportamento dos esforços em bacia com soleira e sem soleira, com vertedouro em degraus e vertedouro de calha lisa. Os dados utilizados foram obtidos em modelo experimental, construído no Laboratório de Obras Hidráulicas (LOH) do Instituto de Pesquisas Hidráulicas (IPH-UFRGS), através de transdutores de pressões fixados junto ao fundo do canal de ensaios para diversas vazões, considerando, além de bacia tipo I, diferentes tamanhos de soleira terminal, situadas em diferentes posições do canal.
Stepped spillways have become a good option in dams for ease of construction and especially to present a significant dissipation of energy throughout the spillway chute, which causes that the parcel of energy to be dissipated by hydraulic jump downstream of dam decreases, causing a significant reduction in the dimensions of the stilling basin structure. The application of end sill in stilling basins causes a better distribution of speeds and better behavior of the fluctuation of pressure along the basin and downstream, thus increasing their performance in energy dissipation. The combination of these two forms of dissipation (stepped spillway and stilling basin with end sill) can be used as an economical and safe solution, however, the sizing of these structures hindered by a lack of criteria and information, especially regarding the ideal size and position for design of an end sill. In this study the data mean pressures and pressure fluctuations within the basin and downstream of the end sill were analyzed, being presented methodologies for design the size and position of a sill as a function of the Froude number of the input of the hydraulic jump. A methodology for analysis of mean pressure in type I basin (without sill) is also being presented, and a comparison of the behavior of efforts in basin with and without end sill, with stepped spillway and flat spillway chute. The data were obtained in an experimental model built at the Laboratory of Hydraulic Works (LOH) at the Institute of Hydraulic Research (IPH-UFRGS), through pressure transducers attached at the bottom of the test channel for various flow rates, considering, in addition of type I basin, different sizes of end sill at different positions of the channel.

Sluice gates are mainly used for controlling discharge through irrigation canals. The flow is termed as free flow or submerged flow when it depends upon upstream head, gate opening and downstream head. When the sluice gate height exceeds some design criteria then double or triple leaf gates are provided. In some cases when double and triple leaf gates are not easy to provide due to some economic reason then a sill is constructed below single leaf sluice gate to reduce its height to meet the desirable design criteria of single leaf sluice gate. The use of stepped sill below sluice gate improves the discharge coefficient effectively. The objective of present study to analyze the experimental data collected on the effect of constructing stepped sill below a sluice gate and validates its parameters through ANSYS-FLUENT. The past studies proved that the trapezoidal sill of downstream slope of 1V:5H improves the discharge coefficient below the gate and produces the minimum increase in the jump length formed downstream compared to other downstream slopes of sills. In this way with constructing stepped sill and the data collected from experiments on the below-gate sill of this particular downstream slope will be analyzed by calculating dimensionless parameter. The experimental analysis carried out on three groups of model made of aluminum sheet and each model of stepped sill have different heights (P = 2, 4, 6 cm respectively) and each physical model is tested with four gate openings as (D = 1.5, 2.0, 2.5, 3.0 cm) respectively. Numerical simulation done in ANSYS and value of discharge coefficient is validated by probe value by calculating pressure, depth of flow and discharge at different section and plot the different contours variation.

Artifacts from the Ancient Silk Road explores the interconnectivity of the Eurasian continent from 4000 BCE to 1000 CE. It focuses on the role played by Central Asia through which passed the major trade routes, the Silk Roads. Artifacts from the Ancient Silk Road covers life along the Silk Road over 5000 years as it can be understood by considering objects. In this first object-based study to consider all of the peoples involved on the Silk Roads, objects provide the vehicles for explorations of different aspects of life for the various peoples of the Silk Roads, including the sedentary peoples who established urban life on the Silk Roads, the steppe nomads who regularly interacted with the settled peoples, and the peoples at either end of the Silk Roads who drove certain kinds of economic exchanges. The book looks at Central Asia as an international zone during ancient times when multiple religious, political, and technological ideas found acceptance in the region and allows for a better understanding of how some ideas and forms developed in Central Asia while others passed through or were modified.

The vast reaches of central Asia are redolent with history, with stirring tales of Marco Polo’s epic journeys and all the romance of the Silk Road, an arduous caravan route that connected Asia and the West for hundreds of years. The archaeology of both central Asia and the Silk Road has yet to reveal all their secrets, for the area presents formidable obstacles for even the most experienced researchers and travelers. A century ago, the obstacles were even more severe—no rail lines, no roads beyond caravan tracks and horse trails, and endemic political instability, to say nothing of harsh deserts and high mountain passes. Despite these obstacles, Afghanistan, Tibet, and other countries along the Silk Road were the arena for what became known in the nineteenth century as the “great game,” the hide-and-seek struggle between Russia and Britain for control of a strategically vital area north of British India. Here, archaeological travel was in the hands of explorers and truly dedicated scientists, and certainly was not the domain of tourists. The logistics and enormous distances ensured that anyone traveling in central Asia vanished from civilization for months, and more often for years. During the nineteenth century, the occasional British army officer and political agent, and also French and German travelers, ventured widely through the region, although their concerns were predominantly military and strategic rather than scientific. The great game culminated in Colonel Francis Younghusband’s military and diplomatic expedition for Britain into Tibet in 1904, prompted by rumors that Russia had its eye on the country. After Younghusband’s return to India and because of his account of the fascinating, mountainous regions to the north, the rugged terrain that formed India’s northern frontier became a place where solitary young officers went exploring, hunting, or climbing mountains for sport. During this period, only a handful of travelers penetrated central Asia with scientific objectives, among them the Swedish explorer Sven Hedin, who traveled via Russia and the Pamirs to China in 1893–1897. He nearly died crossing the western Taklimakan Desert in the Tarim Basin to reach the Khotan River. This huge basin was a melting pot of different religions and cultures, a bridge for silk caravans between East and West.
