Tales voca- no obstante, reflejan con extra- ordinaria justeza que fue aquello que, primordialmente, provoco el maravi- lloso progreso de los dos ultimos si- glos, es decir, esa incesante mejor1a del nivel de vida de unas masas huma- nas en cont1nuo crecimiento.
Lo que los hombres lamentamos - sin, desde luego, la mayor! Consumir mas no dudar, lo deseado - exige mayor produccion. Los de nuestro tiempo, como desde el albor de la humani- dad sucede, solo base de capital pueden ser eficazmente 1 Lo drarnatico, sin embargo, es que el capital solo aparece una economi'a de mercado; en un orden social donde exista la propiedad privada de los medios de produc- cion, los cuales, consecuenternente, pueden ser contratados, registrando as1 sus respectivos correspondientes precios.
El regimen colectivista tiene de capital, pero no sabe que sea capital. Porque el capital no es una rnaterial, si- no un concepto intelectual; es, en definitiva, el valor de do de los medios de produccion que sujeto econornico tiene su disposicion. No constituyen aquellos elementos capital; lo seran solo cuando sur jan, gra- cias al ahorro, los medios que permitan su explotacion.
El ni- vel de vida de un pai's no depende de las riqueza. Por eso, factores de produccion, que, en cierto mo- mento, fueron capital, pueden, despues, dejar de serlo con in- dependencia de su desgaste. Supongarnos una empresa ferro- viaria, hace treinta afios, con un parque de cien locomotoras de vapor, es decir, las, entonces, predominantemente emplea- das.
Constitui'an ellas, la sazon, un capital importante. Esa misma empresa, ahora, con identicas locomotoras, hallar! Junto los investigadores, de- dicados perfeccionar los metodos de produccion, desempe- fian los empresarios, inmediatamente despues de quienes su- pieron ahorrar, papel decisivo en el progreso economico. Los demas no hacemos sino beneficiarnos de la actuacion de aquellos. Cualquiera que sea nuestra actividad, somo simples beneficiar1os de un progreso al que en nada contribuimos.
Lo carac ter stico de la econom:la de mercado es be- neficiar la inmensa mayor:la, que recibe la parte del leon de unas mejoras conseguidas gracias exclusivamente al ac- tuar de aquellos tres grupos rectores, integrados por quienes ahorran, quienes invierten quienes formulas nue- vas que permiten mejor explotar los 11 Estas lucubraciones en torno al concepto de capital nos hacen ver el defecto basico del sOcialismo.
El regimen colectivista, por definicion, exige que factor de produc- cion quede en manos privadas. Dichos son todos pro- piedad del estado de cualquier otro ente colectivo; no pueden ser contratados en ningun mercado por tanto, care- cen de precios que reflejen su respectivo interes social.

La tecnica moderna ha tiempo resolvio cuantas dificultades tal produccion plantea. El hombre rnedio, dominado siempre por su inercia mental, limitar1ase calificar la idea de absurda.
La razon, sin embargo, por la que no producimos hoy agua sin- tetica -aunque tal vez maiiana lo hagamos- es porque el cal- culo econornico nos advierte que se trata del procedimiento rnas caro de todos los conocidos.

A topological spar. This practice is no doubt logically correctt but it 8eems to me to violate the natural relation between these topics, in which metric spaces motivate the more general theory. Metric spaces arP therefore discussed rather fully in Chapter 2, and topological spacPs are intl"oduccd in Chapter 3.
The remaining four chapters in Part 1 are concerned with various kinds of topological spaces of special importance in applications and 'vith the continuous functions carried by them. One of the main features of this book is the attention given to motivating the ideas under discussion. On every possible occasion I have tried to make clear the intuitive meaning of.

George F'. The majority of the problems are corollaries and extensions of theorems proved in the textJ and are freely drawn upon at all later stages of the bookT In generalJ they serve as a bridge between ideas just treated and developments yet to come 1 and the reader is strongly urged to master them as he goes along. It is a basic principle in the study of mathematics, and one too seldom emphasized, that a proof is not really understood until the stage is reached at which one can grasp it as a whole and see it as a single idea.
A proof should be che,ved, swallowed, and digested, and this proces8 of assimilation should not be abandoned until it yields a full comprehension of the overall pattern of thought.In mathematicsa real-valued function f on the interval [ ab ] is said to be singular if it has the following properties:.
A standard example of a singular function is the Cantor functionwhich is sometimes called the devil's staircase a term also used for singular functions in general.
There are, however, other functions that have been given that name. One is defined in terms of the circle map. Singular functions occur, for instance, as sequences of spatially modulated phases or structures in solids and magnetsdescribed in a prototypical fashion by the Frenkel—Kontorova model and by the ANNNI modelas well as in some dynamical systems.
Most famously, perhaps, they lie at the center of the fractional quantum Hall effect. When discussing mathematical analysis in general, or more specifically real analysis or complex analysis or differential equationsit is common for a function which contains a mathematical singularity to be referred to as a 'singular function'. This is especially true when referring to functions which diverge to infinity at a point or on a boundary.
Advanced techniques for working with functions that contain singularities have been developed in the subject called distributional or generalized function analysis. A weak derivative is defined that allows singular functions to be used in partial differential equationsetc. From Wikipedia, the free encyclopedia.

During these years of explora- tion, the role of interferon as natural regulator of various cellular func- tions has expanded beyond the initial area of mediation of antiviral resistancc to include modulation of immune responsiveness and cellular growth and regulation.
Thus its pharmaceutical potential now includes areas of cancer and viral chemotherapy and immune modulation. Yet the answers to ques- tions as basic as what is the structure of this intriguing group of molecules and what is their natural physiological role not clear. This intro- ductory chapter is background for the chapters that follow and therefore will deal with interferon' s "past" and how this fits into its future.
One such determinal1t is the nonspecific resistance initiated and mediated interferon. The term interferon was first applied to soluble factor produced the cells of chicken chorio- allantoic membranes after exposure to il1activated influenza virus .

Ievleva, L. Trushina, R. Baker Middlebury College. The American adapter has worked closely with members of the original team of authors to assure pedagogical effectiveness and adherence to current norms of standard conversational Russian. It is expected that most students will use this textbook in an organized course under the super- vision of a teacher, but the materials should be effective also for use by an individual outside of a for- mal course, particularly if used in conjunction with the supplementary materials available.
It is also expected that college or university courses meeting three hours per week should be able to cover the textbook in one academic year, while high schools will probably find that the materials can be comfortably covered in two years of study.
The availability of a language laboratory for use by the stu- dents at least one hour per week will greatly enhance their active control of the material, particularly in the areas of listening comprehension and speaking. Students who have mastered the elements of the conversational language, including pronunciation and intonation, can easily master the additional elements necessary for mastery of the written literary language.
However, students who have learned first the more bookish literary norms very seldom make the transition to a natural use of the conversational language. Although the teacher may wish to emphasize the acquisition of certain language skills over others in keeping with local circumstances or student interest, the aim of this textbook is a harmonious deve- lopment of all four language skills: listening comprehension, speaking, reading, and writing.

After mastering these materials the student can be ex- pected to speak Russian comfortably and without offending the ears of native speakers on a broad range of everyday and cultural topics, in both mono logic and dialogic speech situations, using the lan- guage in a natural sounding fashion including the use of particles, suitable word order, elliptical sen- tences, etc. Those who are interested in Russian principally as a tool for reading in other disciplines should be able to undertake reading in their own fields of interest with the help of a dictionary.
In adapting the materials for American academic use, the textbook has been reduced to 30 lessons and six review lessons one following each five lessons. We have, however, included four supplemen- tary lessons at the end for schools with more than three contact hours per week.
The grammar content of these lessons will, however, be necessary for reading texts in the written literary language. In cases where only the basic lessons are covered in a formal course, those students who will not be taking further courses but who wish to read Russian, should be able to cover these lessons independently. This course covers practically all major morphological paradigms and syntactic patterns, includ- ing the role of word order in Russian.
At the end of the course the student will also have a good under- standing of Russian word formation and derivation to serve as a foundation for the acquisition of further vocabulary. The version for English-speaking students stresses those morphological and syntactic features which many years of experience have shown to be most troublesome for such students.
Although new grammatical material is first presented in a manner to allow for an inductive assimilation by the observ- ant student, linguistically sound explanations fully adequate for this level of instruction are given throughout. A previous knowledge of grammatical or linguistic terminology is not required, since each new concept is explained in an easily understandable fashion upon its first occurrence.
Students who master the material of this textbook should be able to avoid some of the mistakes of Russian made by many Americans who have been studying the language for a number of years but who did not have the proper foundation laid in the beginning.
Interferon and Interferon Inducers
The lexical units intended for active mastery total about 1, By "lexical units" we refer not to a simple count of words, but to each item which requires memorization, including set expressions with words which are also known individually.These functions can also be characterized as those continuous functions whose distribution derivatives are singular measures without atoms.
Singular functions arise as summands in the Lebesgue decomposition of functions of bounded variation. This name is justified by the fact that the Cantor ternary function is the best known example of singular function.

Two different representative sets of vertices are marked with open circles, and the fundamental region R generated by one set is marked with bold edges. R includes all of the solid edges, and is the union of R and the fundamental regions generated by the five centers marked by inscribed triangles.
Of course, knowing S tells us which vertex of C is equivalent to v', and knowing S for each vertex in C' also describes the struc- ture of R, so there is a good deal of redundant information here. This definition, however, seems to make the proof follow more easily. Exactly how much information about Rand R is needed to give the result of lemma 3. R which covers v'.
