A major flaw in semi-Riemannian geometry is a shortage of suitable
types of maps between semi-Riemannian manifolds that will compare
their geometric properties. Here, a class of such maps called
semi-Riemannian maps is introduced. The main purpose of this book
is to present results in semi-Riemannian geometry obtained by the
existence of such a map between semi-Riemannian manifolds, as well
as to encourage the reader to explore these maps. The first three
chapters are devoted to the development of fundamental concepts and
formulas in semi-Riemannian geometry which are used throughout the
work. In Chapters 4 and 5 semi-Riemannian maps and such maps with
respect to a semi-Riemannian foliation are studied. Chapter 6
studies the maps from a semi-Riemannian manifold to 1-dimensional
semi- Euclidean space. In Chapter 7 some splitting theorems are
obtained by using the existence of a semi-Riemannian map. Audience:
This volume will be of interest to mathematicians and physicists
whose work involves differential geometry, global analysis, or
relativity and gravitation.
Con algunos relatos diferentes entre si, un misterioso hombre trata
de influenciar el estado de animo de dos viajeros a bordo de un
barco que navega con rumbo a un pais desconocido y maravilloso, en
el cual, solo existen la alegria y la felicidad. Durante la
travesia, ese hombre, que se autonombra como un narrador de
historias, en cada relato que les cuenta, hace que la pareja vaya
cambiando el modo de percibir las cosas acerca de diferentes hechos
ocurridos en sus vidas. Casi al final del viaje -que es
completamente surrealista- los viajeros deben decidir por si mismos
si lo terminan, o regresan a su lugar de origen a continuar con sus
vidas actuales, vacias de cosas buenas y llenas de una cruel
desesperanza; a tratar de sobrevivir en un lugar muy triste, donde
no le importan a nadie y que se encuentra dominado por la maldad en
todos su rincones.
Pharmaceutical and fine chemical products are typically synthesised
batchwise which is an anomaly since batch processes have a series
of practical and economical disadvantages. On the contrary, flow
continuous processes present a series of advantages leading to new
ways to synthesise chemical products. Flow processes - * enable
control reaction parameters more precisely (temperature, residence
time, amount of reagents and solvent etc.), leading to better
reproducibility, safer and more reliable processes * can be
performed more advantageously using immobilized reagents or
catalysts * improve the selectivity and productivity of the process
and possibly even the stability of the catalyst * offer
opportunities for heat exchange and energy conservation as well as
an easy separation and recycling of the reactants and products by
adequate process design * achieve multistep syntheses by assembling
a line of reactors with minimum or no purification in between two
reaction steps * can be assured by facile automation * scale-up can
be easily conducted by number-up With all the new research activity
in manufacturing chemical products, this comprehensive book is very
timely, as it summarises the latest trends in organic synthesis. It
gives an insight into flow continuous processes, outlining the
basic concepts and explaining the terminology of, and systems
approach to, process design dealing with both homogeneous and
heterogeneous catalysis and mini- or micro-reactors. The book
contains case studies, extensive bibliographies and reference lists
in each chapter to enable the reader to grasp the contents and to
go on to more detailed texts on specific subjects if desired. The
book is written by both organic chemists and engineers giving a
multidisciplinary vision of the new tools and methodologies in this
field. It is essential reading for organic chemists (in industry or
academia) working alongside chemical engineers or who want to
undertake chemical engineering projects. It will also be of
interest for chemical engineers to see how basic engineering
concepts are applied in modern organic chemistry.
This volume contains research and expository papers on recent
advances in foliations and Riemannian geometry. Some of the topics
covered in this volume include: topology, geometry, dynamics and
analysis of foliations, curvature, submanifold theory, Lie groups
and harmonic maps.Among the contributions, readers may find an
extensive survey on characteristic classes of Riemannian foliations
offering also new results, an article showing the uniform
simplicity of certain diffeomorphism groups, an exposition of
convergences of contact structures to foliations from the point of
view of Thurston's and Thurston-Bennequin's inequalities, a
discussion about Fatou-Julia decompositions for foliations and a
description of singular Riemannian foliations on spaces without
conjugate points.Papers on submanifold theory focus on the
existence of graphs with prescribed mean curvature and mean
curvature flow for spacelike graphs, isometric and conformal
deformations and detailed surveys on totally geodesic submanifolds
in symmetric spaces, cohomogeneity one actions on hyperbolic spaces
and rigidity of geodesic spheres in space forms. Geometric
realizability of curvature tensors and curvature operators are also
treated in this volume with special attention to the affine and the
pseudo-Riemannian settings. Also, some contributions on biharmonic
maps and submanifolds enrich the scope of this volume in providing
an overview of different topics of current interest in differential
geometry.

Open Compositionality: Towards a New Methodology of Language argues
that natural languages, like English and Spanish, are not only
systems of representation useful for communication but also, and
most importantly, highly interactive cognitive capacities allowing
humans to engage in complex forms of cognition. This view goes
against the orthodoxy in philosophy of language, which considers
natural languages to be specialized systems consisting of only
linguistic elements and functioning in a closed compositional
manner, allowing for a fully formal, algebraic descriptions.
Eduardo Garcia Ramirez rejects the longstanding principle of
compositionality, according to which the meaning of any complex
expression is fully determined by its parts and the way they are
combined, and substitutes it with an alternative, open and
interactive one. This novel view of the nature of language better
accounts for the empirical evidence. Garcia Ramirez develops an
account of open compositionality, accompanied by the cognition
first methodology, in which natural languages are conceived as
supermodular cognitive capacities that allow for interaction among
multiple distinct areas of human cognition. The explanatory success
of this novel proposal and its accompanying methodology are tested
by the author's account of three enduring philosophical problems:
substitution failure, empty names, and the nature of moral
discourse.

When Mariana and her new friend, Selena, try to play some
basketball at a local court, they're challenged to a game by two
older girls. If Mariana and Selena win, they get to use the court.
But if the older girls win, they get Selena's special autographed
shirt. Unfortunately, things go badly and the younger girls lose
the bet-and the shirt. However, they soon come up with a plan.
Although some of Mariana's skills are lacking, she's great at
shooting hoops. Will the friends succeed in their hoops hustle to
get back Selena's special shirt?
Historically pharmaceutical and fine chemical products have been
synthesised using batch methods, but increasingly chemists are
looking towards flow chemistry as a greener and more efficient
alternative. In flow chemistry reactions are performed in a reactor
with the reactants pumped through it. It has the benefit of being
easily scaled up and it is straightforward to integrate synthesis,
workup and analysis into one system. Flow chemistry is considered a
greener alternative to batch chemistry because it is easier to
control and minimise hazardous intermediates and by-products. There
is significant interest in the use of flow chemistry both in the
lab and on an industrial scale. Flow Chemistry provides an update
on recent advances that have been made in the field. Particular
emphasis is given to the new integrated approaches that bring
together several elements to implement flow processes as a regular
green chemistry tool for the chemical industries. With chapter
contributions from several well-known experts in the field, this
book is a valuable resource for researchers working in green
chemistry and synthesis, chemical engineers and industrial chemists
working in the pharmaceutical and fine chemicals industries.
