Accurate biochemical knowledge starting with precise structure-based criteria...Michel Dumontier
Biochemical ontologies aim to capture and represent biochemical entities and the relations that exist between them in an accurate and precise manner. A fundamental starting point is the use of identifiers that precisely and uniquely identify some biochemical entity, whether it be a substance, a quality or some biological process. Yet, our current approach for generating identifiers doing so is often haphazard and incomplete. This prevents us from accurately integrating knowledge and also leads to under specification of our knowledge. This talk aims to initiate a discussion on plausible structure-based strategies for biochemical identity, ultimately to generate identifiers in an automatic and curator/database independent fashion, whether it be at molecular level or some part thereof (e.g. residues, collection of residues, atoms, collection of atoms, functional groups). With structure-based identifiers in hand, we will be in a position to accurately capture specific biochemical knowledge, such as how a set of residues in a binding site are involved in a chemical reaction including the fact that a key nitrogen atom must first be de-protonated. Thus, this will enhance our current representation of biochemical knowledge and make it fundamentally more useful.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

"Dreams are often most profound when they seem the most crazy" (Sigmund Freud). "Il est établit que nous ne pensons qu'avec le secours des
mots; que les langues sont de véritables méthodes analytiques; que l'algèbre la plus simple, la plus exacte et la mieux adaptée à son objet de

mot doit faire naître l'idée; l'idée doit peindre le fait : ce sont trois empreintes d'un même cachet ; et, comme ce sont les mots qui conservent les
idées et qui les transmettent, il en résulte qu'on ne peut perfectionner le langage sans perfectionner la science, ni la science sans le langage, et
que, quelque certains que fussent les faits, quelque justes que fussent les idées qu'ils auraient fait naître, ils ne transmettraient encore que des
impressions fausses, si nous n'avions pas des expressions exactes pour les rendre" (A. Lavoisier, Traité élémentaire de Chimie, 1789). "La

when I don't know what I'm doing (Wernher von Braun). "..dove la natura finisce di produrre le sue specie, l'uomo quivi comincia con le cose

25. Knowledge?
Knowledge differs from data or information in that new knowledge
may be created from existing knowledge using logical inference. If
information is data plus meaning then knowledge is information plus
processing (http://www.thefreedictionary.com/knowledge)
Kowledge can include facts and information, as well as understanding
that is gained through experience, education or reason. It can be:
implicit (as with practical skill or expertise) or explicit (as with the
theoretical understanding of a subject), more or less formal or
systematic (http://en.wikipedia.org/wiki/Knowledge)
Knowledge is human faculty resulting from interpreted information;
understanding that germinates from combination of data, information,
experience, and individual interpretation.
http://www.businessdictionary.com/definition/knowledge.html
Knowledge has come to be recognized as a factor of production in its
own right, and distinct from labor.
26. Learning ?
Learning is acquiring new or modifying existing knowledge, behaviors,
skills, values, or preferences and may involve synthesizing different
types of information.
The ability to learn is possessed by humans, animals and some machines
Human learning may occur as part of education, personal development,
or training. It may be goal-oriented and may be aided by motivation.
The study of how learning occurs is part of neuropsychology,
educational psychology, learning theory, and pedagogy.
Learning may occur as a result of habituation or classical conditioning,
(seen in many animal species, or as a result of more complex activities
such as play, seen only in relatively intelligent animals). Learning may
occur consciously or without conscious awareness.
Play has been approached by several theorists as the first form of
learning. (Lev Vygotsky, Social constructivism)
27. Learning?
Learning is the act, process, or experience of gaining knowledge
or skill (The free dictionary)
Learning is knowledge or skill gained through schooling or study
(The free dictionary)
Learning is behavioral modification especially through experience
or conditioning (The free dictionary)
Learning is measurable and relatively permanent change in behavior
through experience,
Learning is "detection and correction of error" where an error
means "any mismatch between our intentions and what actually
happens" (Harvard Business School psychologist Chris Argyris)
(Business dictionary
28. E-Learning?
E-Learning
E-learning is essentially the computer and network-enabled transfer of
skills and knowledge. E-learning applications and processes include
Web-based learning, computer-based learning, virtual classroom
opportunities and digital collaboration. Content is delivered via the
Internet, intranet/extranet, audio or video tape, satellite TV, and CD-
ROM. It can be self-paced or instructor-led and includes media in the
form of text, image, animation, streaming video and audio (Wikipedia).
E-learning that is supported by information and communication
technologies (ICT). E-learning is, therefore, not limited to ‘digital
literacy’ (the acquisition of IT competence) but may encompass
multiple formats and hybrid methodologies, in particular, the use of
software, Internet, CD-ROM, online learning or any other electronic or
interactive media (European Commission).
29. Chemistry ?
Chemistry is the science of matter
Chemistry is the branch of the natural sciences dealing with the
composition of substances and their properties and reactions.
(wordnetweb.princeton.edu/perl/webwn)
Chemistry is the science of the composition, structure, properties, and
reactions of matter, especially of atomic and molecular systems.
http://www.thefreedictionary.com/chemistry
Chemistry is the art of resolving mixt, compound, or aggregate bodies
into their principles; and of composing such bodies from those
principles (Stahl, 1730, Philosophical Principles of Universal Chemistry. London.)
Chemistry is the science of substances: their structure, their
properties, and the reactions that change them into other substances
(Pauling, Linus, 1947, General Chemistry. Dover Publications, Inc.. ISBN 0486656225.
Chemistry is the study of matter and the changes it undergoes
(Chang,1998, Chemistry, 6th Ed.. New York: McGraw Hill. ISBN 0-07-115221-0)
