Abstract:
Water birds have contour feathers in contact with water that show in their distal one-third adaptations to water repellency, resistance to water penetration and forceful impact with water. These qualities vary according to their intimacy with open water. In this study, the geometry of this part of the feather was examined to detect additional features that would affect viscous drag in water. The length-to-width ratio was measured and used to calculate the viscous drag coefficients for 48 water birds and, for comparison, 12 land birds. The lowest values for the drag coefficient were observed for birds with foraging niches as diving and swimming, followed by plunging, surface feeding, aerial and ground feeding. Land birds with no open water in their habitat had the highest drag coefficients. Three statistical approaches were used to validate the results. Allowing for the phylogenetic relatedness of the 60 species obscured any significant differences that may exist, but a non-parametric analysis that does not assume the conditions of equal sample size and variance turned out to be the most appropriate method for our data set.

Abstract:
Many of us who work with pencil, pen, or computer like to vary the intellectual routine by doing something “real.” Some build cabinets and canoes, some sing in choral groups, others join first aid squads. I take care of our garden. Gardening is an especially good activity for eggheads because it combines physical labor with the opportunity to be creative. Unlike the ideas in the books I write, however, my creations in the gar-den are quickly put to the test. My experience last summer is a case in point. I like to eat what I grow, so I have little patience with flowers and other ornamentals. I tolerate the ones that were planted around the house when we first arrived: yew, hemlock, cherry laurel, forsythia, flame azalea—the usual things provided by botanically challenged, cost-conscious builders. If these woody perennials get sick I do what I can for them, given my lack of knowledge and low level of interest. Some times I fertilize, sometimes I continue to refrain from fertilizing, depending on my intuition in the particular case. The same goes for watering. Our flame azalea is down to one tiny branch with eleven leaves on it, about the same as last year. I don’t know whether I am keeping it alive against all odds, or preventing it from making the full recovery that it would be capable of if cared for by somebody else. I view my role in the treatment of our ornamental plantings like that of the remote HMO clerk who makes the critical decisions in a complex medical case; any unfortunate consequences of my ignorance are not of great concern. Fruits and vegetables are another matter. I am not much more knowledgeable about them than about azaleas, but I try a lot harder. Because this is a story about vegetables, I will skip the fruits, except to note that we pick our own sour cherries, figs, peaches, plums, grapes, apricots, and apples—in sharply decreasing order of abundance (squirrels got all of my apples this year).

Abstract:
To begin with a little anecdote. There is a classroom, an ugly, badly shaped, windowless room in a modern university building designed with students not in mind. In this room there is a small class, my class. We have rearranged tables and chairs in a semicircle around my place to defy the terrible ambience and to allow all twenty-five students to see and hear each other and me. Class is in session; I am talking. Two students sitting together in the front row—a thirty-year-old man with a pager on his belt and a twenty-year-old woman—are speaking to each other and laughing quietly; they see that I am looking at them and they continue to laugh, not furtively or offensively but openly and engagingly, as if I weren’t there. I don’t know what they are laughing about. Both of these students will eventually receive an A in the course for their exceptionally fine work. As I speak to the class, a part of my mind is thinking about these students and wondering why they are laughing. Is there chalk on my face? Is my fly open? Have I repeated myself or unconsciously misused a word or inverted a phrase? Then I remember something Bruce Wilshire wrote, and the paranoia fades. The laughter has nothing to do with me. Bruce, a philosopher who works in a nearby building on campus, described the same attitude in his own classes in his book, The Moral Collapse of the University. This passive and casual rudeness, a fairly new phenomenon, has a simple cause, he said: “I sometimes see students looking at me as if they thought I could not see them, as if I were just somebody on their screen.” When my students were laughing, it didn’t occur to them that I would be bothered—at that moment they were treating me as if I were a face on television. That’s what it is; I am sure of it. The students (at least most of them) and I inhabit different worlds, even when we sit in the same room.

Abstract:
The semester is over, my grade rosters have been handed to the registrar, and I am home, writing sporadically and glancing through a book by P. G. Wodehouse, whose incomparable prose, as elegant as it is funny, is always very soothing. The thirty students in Conservation Ecology were very good this year. Most of them were informed, outdoors-loving, committed, hard working people who cared for each other and seemed to enjoy the class. With a few exceptions, however, they can’t write English, and I am still recovering from the effects of reading the term papers upon which their grades were largely based. For twenty-five years, I have been assigning a major term paper in lieu (“in loo,” as one student wrote) of an exam. I used to get eighteen- to forty-page papers, acceptably or even nicely written; now the students struggle to reach fourteen pages with the help of triple spacing, margins you could drive a bus along, and type sizes usually reserved for the visually disabled. And the writing! The first mistake the students are making is to use the “spell-checkers” of their computer software as a substitute for proofreading. The results are papers in which all the words are spelled correctly, even if they are not the right words. Reading these spell-checked papers can be like trying to translate from Spanish to English based on the assumption that words that are spelled the same in the two languages have the same meaning. (This can lead to some confusion if, for example, the Spanish words are sin, cabal, or saber.) In one of the papers, I had to erase a long, marginal comment I had written when I realized that illicit was meant to be elicit. In another, I had trouble with the philosophical implications of the word modal, used throughout the text, until I turned it into model, which made more sense. Then there were words such as begum (“a Muslim lady of high rank,” my dictionary told me), which didn’t seem to fit easily into the context of a paper on the genetics of coyotes, and which didn’t have an obvious substitute.

Abstract:
Having won acclaim with his receiving India’s highest literary honour, the Sahitya Academy Award, he set his sights on encouraging Dalit writers and thinkers to express themselves in their own words, helping them find their own authentic voices, without regard to the vast literature that was essentially canonical and brahminical in origin. He hoped that this would help heal the wounds that the Untouchables felt deeply as a result of the deprivations that they had experienced for generations. At the same time, he also pointed to the varied and opposing interpretations of stories and parables from the great Indian epics, Ramayana and Mahabharata. His distillation of the vast span of Vedic and Vedantic literature offered depth and meaning extending from the ancient Sanskrit to the contemporary nascent Dalit literature. Marathi Dalit literature blossomed during this time and saw extraordinary growth. He expanded his analysis and thinking into other creative realms including the aesthetics of art, poetry, and drama.

Some people have a drink when they get home from work—a martini, a beer. Maybe two or three. Life is especially stressful in the twenty-first century. The same indecent forces that are destroying nature are disrupting our working lives as well. Who will own the company tomorrow? Will there be a “reduction in force” or some other euphemism for the ax? When is the next reorganization coming? Is my ten or twenty years of faithful service an asset or, more likely, a sign of obsolescence and suspicious loyalty to bosses and co-workers now out of favor or working for other companies? How am I to answer the fax that arrived at 4:00 p.m., the one that seemed to contradict the fax that arrived at 11:00? When will I find time to fill out the questionnaire from the Resource Management Office, and does it take precedence over the Goals Enhancement Strategy questionnaire that came from the Administrative Services Division? Are my computer files compatible with the new software system, and, if so, why did the box on the screen say, “This paragraph is un-readable. Do you wish to substitute a standard paragraph?” Just what is our real work, anyway? Alcohol can take the edge off stress, but it is not everyone’s consolation. Some choose television or the Internet; mine is to pick up one of the scores of detective novels that I keep close to hand and plunge in. Then I can forget for a little while the vice presidents, deans, and other academic, corporate-style bosses who do their best to make life in the modern university an unproductive misery. In this way I can put out of mind, temporarily, the pleas of students who don’t understand why there are no courses to take and the ravings of colleagues who can’t figure out how to cope with the contradictory, impossible demands placed on them. Why should detective stories be, for so many, such a good and entertaining way of escaping from reality? That they are is clear; billions of copies have been sold.

Abstract:
At the end of the Cretaceous period, the last dinosaurs disappeared from the earth, setting off an evolutionary jubilee among the Milquetoast-like mammals that survived them, and preparing the ground for what was to become, 65 million years later, a permanent source of gainful occupation for scientists whose job it is to wonder why the dinosaurs died out. Scores of reasons have been given for this remarkable concatenation of extinctions. Global climate and sea level were changed by a city-sized asteroid striking the earth near what is now the Yucatan, or by a massive set of volcanic eruptions, or by the solar system passing through the core of a giant molecular cloud, perhaps colliding with a supercomet loosened from the Oort cluster, which orbits the Sun beyond Pluto. Theories of catastrophic extinction abound. Some of the most daring even conjure up the specter of an unseen companion star to our Sun, named Nemesis, whose eccentric orbit brings a wave of potentially deadly comet showers—and extinctions—every 26 million years. But there are also paleontologists who argue that the dinosaurs went away gradually, not suddenly, over a period of millions of years, and that toward the end they coexisted with the earliest hooved mammals, including ancestors of horses, cows, and sheep. If extinction was gradual, a different line of thought opens up: perhaps the dinosaurs died out because they couldn’t adapt and compete in a changing world. The big lummoxes were obsolete. I heard about the dinosaurs’ obsolescence back in my student days. It was as satisfying a notion then as it is today, especially if you didn’t think about it too hard. Here were these lumbering, pea-brained reptiles, barely able to walk and chew gum at the same time, while all around and underneath them, cleverly hiding behind clumps of primitive vegetation and cleverly burrowing in tunnels in the ground, were the nerdy but smart little mammals about to emerge from the shadows and begin their ascent to glory—somewhat, it occurs to me now, like Bill Gates in the waning days of heavy manufacturing.

Abstract:
My old college housemate Claude had dropped by for one of his stimulating visits, an infrequent happening even though his apartment on Manhattan’s Upper West Side was only an hour away by car. In college, we had been utter opposites in interests and temperaments—Claude’s direction was art criticism, which he celebrated with an élan that gained him a wide circle of friends. Mine was biology, and shyness was my distinguishing social feature. A shared liking for history and the attraction of very different personalities formed a narrow bridge between us, enough to have kept us in occasional contact over the years. We had been discussing European politics and the question of de-centralism over a light lunch on the patio, and then, in one of those curious shifts that conversations take, we had abruptly changed the subject. He was holding forth in his usual compelling fashion. “The trouble with nature writing,” Claude said, “is that it’s so artistically accepting, so uncritical. Lopez, Abbey, and their ilk—why civilization seems to have passed them by without leaving a mark. Culture implies the ability to discriminate, to judge—not sometimes, all of the time. Why should nature be exempt from criticism?” He readjusted his long, elegantly trousered legs carefully on the lounge chair, glared briefly across the patio at a song sparrow sitting on a dead branch of my Cortland apple tree, and continued. “I fail to comprehend why you nature-lovers don’t hold nature to the same kind of ex-acting standard that a cultured person applies to a bottle of Margaux or a performance of Rosenkavalier. Undiscriminating adulation is barbaric.”Just then a starling arrived at the bird feeder, displacing a blue jay. “Do you see that?” cried Claude. “That is exactly what I mean.” “Too aggressive?” “No, no, that’s not it at all. Look at the preposterous thing. Surely you can see what I’m referring to?” “All I see is a starling. It seems healthy.” “It seems healthy!” Claude stared at me in disbelief. “You’re not understanding me. Try to look at it as if it were a painting, a painting you did in beginner’s art class.

Abstract:
he Jewish holiday of Sukkot has set me thinking about ritual traditions, wondering why they assume their curious forms and how they can out-live their originators and persist for such a very long time. Sukkot, or the feast of Tabernacles, more than any other religious holiday I observe, is defined by odd practices that make no obvious sense, yet they have been performed in approximately the same way every autumn for at least twenty-five hundred years. Although many of my friends feel that tradition sanctioned by religious authority is quite sufficient reason for observing the Sukkot rituals, I find it hard to eat a festive meal outdoors in October in a cramped and flimsy three-sided booth incompletely roofed with cornstalks, without asking myself, “Why am I doing this?” The answer, “Because your biblical ancestors spent forty years in the wilderness living in temporary booths or tents,” is adequate up to a point, but it doesn’t help to explain why, during six of the seven days of the festival, I am obliged to take four species of plants, a citron and an immature palm frond bound together with two branches of willow and three of myrtle, and point them successively east, south, west, and north, then down toward the earth and up toward the sky. The scriptural origin of the four species used during Sukkot is simple enough. In Leviticus 23:40, instructions are given that beginning on the first day of the holiday, you shall take “the fruit of goodly trees, branches of palm trees, and boughs of thick trees, and willows of the brook, and you shall rejoice before the Lord your God seven days.” No wasted words, no explanations. It was left to postbiblical rabbinic interpretation to fill in the needed details and standardize the ritual. Thus “the fruit of goodly trees became the citron (etrog in Hebrew), and the “boughs of thick trees” were declared to be myrtle branches. The method of attachment of the willow and myrtle sprigs to the palm frond (lulav), using strips of palm, was specified by the rabbis, as was the notion of waving the species in different directions.

Abstract:
Sport events have become a key element in revitalizing tourism and a valuable instrument for city marketing managers. This is true not only for mega-events but also for medium and small-size events. This chapter focuses on two editions of the same sport event as an example of how it can be used for these purposes. The authors have chosen the Spanish Swimming Master Championship celebrated in the city of Pontevedra in 2011 and 2015. The choice of the city is justified by its concern about celebration of sport events during the last decade as a means of promoting the city and increasing tourism.

Abstract:
Abstract The ability of a swimming robot to extract information from a vortex field in the ambient fluid flow has immense practical applications. Such capabilities perhaps augmented with other sensors are useful to detect and avoid obstacles or potential adversaries in the fluid. This has led many researchers to attempt to sample the pressure field on the surface of a swimmer and thus extract information about the fluid flow such as the flow velocity and angle of attack. In contrast in this paper, we show through simulations, that the kinematic information of a swimmer, specifically its angula

Abstract:
Microogranisms such as sperm and E. coli swim in a low-Reynolds number environment. In the zero-Reynolds-number Stokes limit, their kinematics are completely controlled by viscous forces and inertia is unimportant. This swimming environment is quite different from our usual (high Reynolds number) intuition about swimming. For example, due to the kinematic reversibility of Stokes flow, motions that look the same going forward and backward in time, such as the linear motion of an oar-like appendage, do not lead to net translation. Thus microorganisms in Newtonian fluids use swimming motions with

This paper presents vibration analysis and structural optimization of a self-assembled structure for swimming. The mode shapes of the structure resemble the body waveform of a swimming Mackerel fish. The lateral deformation waveform of the body of Mackerel is extracted from literature. At higher swimming speeds fish generate the waveform at a higher frequency. Their body waveform stays the same at almost all normal swimming speeds. At the final destination, the box self-assembles using shape memory alloys. The shape memory alloys used for configuration change of the box robot cannot be used fo

In this work, we numerically studied the steady swimming of a pufferfish driven by the undulating motion of its dorsal, anal and caudal fins. The simulations are based on experimentally measured kinematics. To model the self-propelled fish swimming, a Computational Fluid Dynamics (CFD) tool was coupled with a Multi-Body-Dynamics (MBD) technique. It is widely accepted that deformable/flexible or undulating fins are better than rigid fins in terms of propulsion efficiency. To elucidate the underlying mechanism, we established an undulating fins model based on the kinematics of live fish, and con

Swimming fishes exhibit remarkable diversities of the caudal fin geometries. In this work, a computational study is conducted to investigate the effects of the caudal fin shape on the hydrodynamic performance and wake patterns in flapping propulsion. We construct the propulsor models in different shapes by digitizing the real caudal fins of fish across a wide range of species spanning homocercal tails with low aspect ratio (square shape used by bluegill sunfish, rainbow trout, etc.) or high aspect ratio (lunate shape adopted by tuna, swordfish, etc.), and even heterocercal caudal fin adopted b

Basically, the controllability of Paramecium in the vertical plane is not so different to the controllability in the horizontal plane. We can control paramecium very stably for over 100 laps along the star-shaped target route by using this newly made experimental pool. The controllability was improved with the

Abstract In the present study, an immerse-boundary-method-based in-house numerical solver is employed to investigate the effects of school pattern on energetics in fish-like swimming. Following Weihsys theory, two-dimensional diamond schools are formed for numerical simulations. The effects of the lateral distance and the longitudinal distance have been investigated to reveal the energetic saving mechanism in a fish school. It is found that the energetic performance in a narrow diamond school (2dy = 0.4) is very different from that in a wide school. In the wide school, the beneficial effect wi

The issue of strengthening the supporting structure of the swimming pool building, with a special attention on damaged reinforced concrete pillars in the sub-pool, is presented. The technical condition of those pillars in the basement of the swimming pool was defined as the risk of structural collapse. Numerous cracks and the occurrence of deformation of reinforcing bars were noticed. Three columns were damaged in basement rooms. First of all, the cause of damage was determined. The actual load carrying capacity of the built pillars was checked. To this aim, the geometry of the columns was che
