Decentralized, off-grid power supplies such as micro-hydropower can be perceived as expensive investments by poor countries like Nepal. Can these investments be justified by the benefits that electricity brings to villages in remote mountainous regions? This book describes research into the development gains brought to such villages, measured in terms of progress towards achieving the millennium development goals. Indicators relating to income, education, gender equality, maternal and child health and environmental impact were measured in villages benefiting from micro-hydropower, compared with neighboring villages without an electricity supply.

The cumulative development advantages were found to far outweigh the investment costs of a micro-hydropower system. The household income benefits and cost savings associated with an electricity supply were found to be considerable, and to outweigh the investment costs of micro-hydropower over the lifetime of an installation. Where businesses that exploited the new energy supply had been started, the income gains were even more marked. In addition, there were other significant development benefits in terms of education, gender equality and health.

Decentralized Energy Access and the Millennium Development Goals provides conclusive evidence of these transformative benefits and recommends that Nepal, and countries like it, scale up investments in its micro-hydropower program.

Excerpt: ... it is one of the surest and most profitable crops, as the plant is subject to Do disease, nor is it liable to be annoyed by any insect; droughts do not sensibly affect its growth, and it is in uo danger of being destroyed by cattle. From two to three bushels of seed are requisite to the acre; twe where the soil is not the richest, and from that allowance up to three io I hose capable of affording greater products. The seed must be of the year next preceding, as it quickly loseB its germinative powers. A ton of hemp, when dressed, may be raised from two acres of land of the highest fertility; but in the bog meadows of Orange county, in this state, where the culture of the crop is mostly attended to, the usual product is about a ton from four acres. There, the crop is cultivated several years successively on the same lands. Whether the manuring of those lands with upland ea'rths, particularly those of a saudy composition, has ever been put into practical operation, I have not understood; but it is believed that no manure, so cheaply afforded, will produce equal effects, on lands of that description. But as uplands, or (hose of alluvial formation, are the soils to which cultivators will be found almost exclusively restricted in the culture of (he crop, except in that comity, I shall confine myself more particularly to its culture in soils of those descriptions. Where the land is to be sufficiently enriched by fresh barn-yard manure, the better way perhaps is to break up the ground in the fall; in the spring following cart on the dung, say, at the rate of fifty loads to the acre; plough this under, with a deep furrow, and cultivate the ground, for that season, with some hoed crop; the next spring mellow the ground effectually-with the plough, lay the furrows ...

Excerpt: ... ABSTRACTS. i. THE WOLF AND LUCKY-MAN CREATE LAND. Wolf and Lucky-Man meet on shore of big lake, where two ducks are swimming. Wolf challenges Lucky-Man to see who can endure rain longest. LuckyMan wins. Wolf sends Duck down to fetch dirt from bottom of lake. Duck brings up mud, which Wolf throws.in north and forms into prairie. Lucky-Man sends Duck for more mud, which he throws on south side of Wolfs land. Hills and mountains are formed and buffalo are on land. There is channel between two countries created, occupied by Missouri River. 2. THE SPIDERS GIVE BIRTH TO PEOPLE. Wolf and friend change Spider-Man and Woman by rubbing them with wild sage dipped in water and teach them how to lie together. Their progeny are human beings. 3. THE ORIGIN OF THE ARIKARA. Large people on earth long ago destroyed by flood, by Nesaru. People turn into corn and are put into cave with animals. Nesaru turns ear of corn into woman and sends her to bring people from earth. People and animals know her. Badger, Mole, and long-nosed Mouse offer to help her to take people out. They dig in turns. Thunder opens earth. People go out upon earth, journey west, leaving behind Badgers, long-nosed Mice, Moles, and some people who turn back into earth and become animals. People come to great basin, which Kingfisher fills up by striking bill into banks. Journey is continued until people stopped by timber, which is removed by Owl. They come to big lake. Loon parts waters. Mother-Corn returns to heavens. People here make games, first shinny and then javelins, to catch ring with. Winners kill those of other side. Mother-Corn returns to give people rules to go by. Man is selected as chief. He instructs people as to scalping. Mother-Corn makes bundle, songs, ritual, and ceremonies. Man instructs...

Excerpt: ... PART III. THE GENETIC AND THE OPERATIVE EVIDENCE. The genetic and operative evidence shows that there has been included under the general term "secondary sexual characters" a complex of cases that are the outcome of diverse physiological processes. Sex-linked and sex-limited characters have often been confused; some characters depend on the gonad; some of these involve the ovary, others the testes. Still other characters fall under none of these groups, but are the direct product of the male or female genetic constitution. It is not surprising, therefore, that theories proposed on the information derived from certain of these data are controverted by information derived from other data. The theory of sexual selection, in its attempt to bring all the facts under one point of view, has not escaped these difficulties, even although it may be said that neither natural selection nor sexual selection is concerned with the origin or even the kind of variations with which it works. Nevertheless, the latter theory, by ignoring the origin or the physiological process concerned in the production of secondary sexual characters, may make assumptions that are difficult to harmonize with the facts in the case, and we shall find several instances of this sort. For example, if the hen had selected the cock for his fine plumage (which, as we have seen, depends in part on autosomal genes producing their effect without the cooperation of the testes), she would be expected to endow herself with the same adornments (if her selection worked), unless her ovary were already producing some substance inimical to those that she is "calling forth" by selection of the male. The problem is evidently, then, more complex than appears on the surface, and is not so simple as it seemed when...

Excerpt: ... IV. NEW CHEMICAL REACTIONS PRODUCED BY LIGHT. 1868-69. Measured by their power, not to excite vision, but to produce heat--in other words, measured by their absolute energy--the ultra-red waves of the sun and of the electric light, as shown in the preceding articles, far transcend the visible. In the domain of chemistry, however, there are numerous cases in which the more powerful waves are ineffectual, while the more minute waves, through what may be called their timeliness of application, are able to produce great effects. A series of these, of a novel and beautiful character, discovered in 1868, and further illustrated in subsequent years, may be exhibited by subjecting the vapours of volatile liquids to the action of concentrated sunlight, or to the concentrated beam of the electric light. Their investigation led up to the discourse on 'Dust and Disease' which follows in this volume; and for this reason some account of them is introduced here. A glass tube 3 feet long and 3 inches wide, which had been frequently employed in my researches on radiant heat, was supported horizontally on two stands. At one end of the tube was placed an electric lamp, the height and position of both being so arranged, that the axis of the tube, and that of the beam issuing from Fig. 2. the lamp, were coincident. In the first experiments the two ends of the tube were closed by plates of rocksalt, and subsequently by plates of glass. For the sake of distinction, I call this tube the experimental tube. It was connected with an air-pump, and also with a series of drying and other tubes used for the purification of the air. A number of test-tubes, like F, fig. 2 (I have used at least fifty of them), were converted into Woulf'a flasks. Each of them was stopped by a cork, through...

Excerpt: ... GLOSSARY OP THE PRINCIPAL SCIENTIFIC TERMS USED IN THE PRESENT VOLUME. Aberrant.--Forms or groups of animals or plants which deviate in im« portant characters from their nearest allies, so as not to be easily included in the same group with them, are said to be aberrant. Aberration (in Opties).--In the refraction of light by a convex lens the rays passing through different parts of the lens are brought to a focus at slightly different distances,--this is called spherical aberration; at the same time the coloured rays are separated by the prismatic action ot the lens and likewise brought to a focus at different distances,--this is chromatic aberration. Abnormal.--Contrary to the general rule. Aborted.--An organ is said to be aborted, when its development has been arrested at a very early stage. Albinism.--Albinos are animals in which the usual colouring matters characteristic of the species have not been produced in the skin and its appendages. Albinism is the state of being an albino. ALCLE.--A class of plants including the ordinary sea-weeds and the filamentous fresh-water weeds. Alternation Of Generations.--This term is applied to a peculiar mode of reproduction which prevails among many of the lower animals, in which the egg produces a living foan quite different from its parent, but from which the parent-form is reproduced by a process of budding, 01 by the division of the substance of the first product of the egg. Ammonites.--A group of fossil, spiral, chambered shells, allied to the existing pearly Nautilus, but having the partitions between the chambers waved in complicated patterns at their junction with the outer wall of the shell. Analogy.--That resemblance of structures which depends upon similarity of function, as in the wings of insects ...

Walter M. Fitch, a pioneer in the study of molecular evolution, has written this cogent overview of why creationism fails with respect to all the fundamentals of scientific inquiry. He explains the basics of logic and rhetoric at the heart of scientific thinking, shows what a logical syllogism is, and tells how one can detect that an argument is logically fallacious, and therefore invalid, or even duplicitous. Fitch takes his readers through the arguments used by creationists to question the science of evolution. He clearly delineates the fallacies in logic that characterize creationist thinking, and explores the basic statistics that creationists tend to ignore, including elementary genetics, the age of the Earth, and fossil dating. His book gives readers the tools they need for detecting and disassembling the ideas most frequently repeated by creationists.

Excerpt: ... organism, but also with respect to the size and configuration of its. component parts. It would have been easy, by selecting only the most divergent types from amongst the whole series of specimens which I have examined, to prefer an apparently substantial claim on behalf of these to be accounted as so many distinct species. But after having classified the specimens which could be arranged around these types, a large proportion would yet have remained, either presenting characters intermediate between those of two or more of them, or actually combining those characters in different parts of their fabric; thus showing that no lines of demarcation can be drawn across any part of the series that shall definitely separate it into any number of groups, each characterised by features entirely peculiar to itself.' At the conclusion of his enquiry he states--I. The range of variation is so great among Foraminifera as to include not merely the differential characters which systematists proceeding upon the ordinary methods have accounted specific, but also those upon which the greater part of the genera of this group have been founded, and even in some instances those of its orders. II. The ordinary notion of species as assemblages of individuals marked out from each other by definite characters that have been genetically transmitted from original proto-types similarly distinguished, is quite inapplicable to this group; since even if the limits of such assemblages were extended so as to include what elsewhere would be accounted genera, they would still be found so intimately connected by gradational links that definite lines could not be drawn between them. III. The only natural classification of the vast aggregate of diversified forms which this group contains wil...

Excerpt: ... ADDRESS OF HON. ADDISON BROWN, ON THE NEED OF ENDOWMENT FOR SCIENTIFIC RESEARCH AND PUBLICATION. Twenty years ago Prof. Tyndall delivered in New York and in other cities of this country a series of lectures upon light. The last of the series was an impressive plea for a more thorough prosecution of original research in pure science; and incidentally, for the need of endowments to maintain it. I was fortunate in having the opportunity to listen to that remarkable course of lectures and to that plea for science. Its impression has never left me. The impression was the deeper, because Tyndall set upon it the seal of self-denial. Some $30,000, nearly the entire net proceeds of his lectures in the United States--money for which he undoubtedly had abundant use in his own affairs, or at least in the prosecution of researches in his own country, and which by all precedent and the example of other lecturers he would have taken with him--all this he has given to the science of this country, endowing therewith, in 1885, three scholarships for the prosecution of original research in physics, one under the direction of Columbia College, one under Harvard, and a third at the University of Pennsylvania. The truths uttered and the example set by this self-denying master have already many times borne fruit. The late President Barnard, of Columbia College, who was a warm supporter of Prof. Tyndall when here, bequeathed to Columbia upon his decease a few years since, the sum of ten thousand dollars for the endowment of anotlur fellowship, for the encouragement of scientific research, upon substantially the same terms as those of the Tyndall Scholarships. In other parts of the country there have been some other endowments for similar purposes. In the last year Columbia has a...
