Reinterpretación y lectura contemporánea de los íconos gráficos de las fiestas del inti raymi de salcedo, enfocada en la figura del danzante
No full textSalcedo canton is a noble, hospitable land, with great cultural and traditional wealth, currently in process of devaluation due to the effects of globalization. For this reason, it is proposed to carry out the design of graphical icons based on the clothing of “Danzante de Salcedo”, to there by revalue the cultural identity of the sector and to inform the population the meaning of the icons that make up the clothing of this important character of the festival of “Inti Raymi Salcedo”. For the development of this project, we worked together with the people of the region and the author of the book "Los Danzantes del Inti Raymi: identity traits," Dr. Wilmo Gualpa to gather information about these celebrations. From literature and field research, the relevance of this research project focused on the figure of Danzante and his clothing was defined. With the information gathered, we proceeded to the development of the project, where they intervened knowledge gained throughout the race Computerized Graphic DesignEl cantón Salcedo es una tierra noble, hospitalaria, con grandes riquezas culturales y tradicionales, actualmente en proceso de desvalorización, debido a los efectos de la globalización.

Mining housekeeping genes with a Naive Bayes classifier
No full textThe first author was supported by the Student Awards Agency for Scotland. The second author is supported by BBSRC grant BBS RC BB/D006473/1, and under the Advanced Knowledge Technologies (AKT) Interdisciplinary Research Collaboration (IRC), which is sponsored by the UK Engineering and Physical Sciences Research Council under grant number GR/N15764/01.Background: Traditionally, housekeeping and tissue specific genes have been classified using direct assay of mRNA presence across different tissues, but these experiments are costly and the results not easy to compare and reproduce. Results: In this work, a Naive Bayes classifier based only on physical and functional characteristics of genes already available in databases, like exon length and measures of chromatin compactness, has achieved a 97% success rate in classification of human housekeeping genes ( 93% for mouse and 90% for fruit fly). Conclusion: The newly obtained lists of housekeeping and tissue specific genes adhere to the expected functions and tissue expression patterns for the two classes. Overall, the classifier shows promise, and in the future additional attributes might be included to improve its discriminating power.Peer reviewe
Analysis of the fire resistance of timber jack arch flooring systems used in historical buildings
No full text[EN] Conservation of built heritage, at present, is a major task and a great challenge because it requires adapting the performance of existing buildings to current code requirements, when very often these were built before codes existed. Timber jack arch flooring systems can be found in many historical buildings around the world. The system is formed by timber joists and brick vaults spanning the distance between two adjacent joists and has an undoubtable aesthetic and cultural value. However, given its geometry, there is no methodology to verify its fire resistance, which has prevented the preservation of many buildings using this system. Within this context, this paper proposes a methodology based on the ¿Reduced cross-section method¿ included in Eurocode 5 (EN 1995-1-2) for the determination of the fire resistance of historical timber jack arch flooring systems subjected to different fire exposures. The methodology is based on the use of the 135-degree and the 300-degree isotherms to obtain the positions of the zero-strength layer and the charring depths, and is supported by both advanced numerical thermal models experimentally validated for standard fire exposure and advanced mechanical models. The methodology has been applied to a wide number of flooring systems covering different span lengths, timber static bending strengths, and fire exposures to evaluate the influence of these parameters on fire resistance. Results show that historical buildings do not always meet the requirements set by current codes and, therefore, performing these analyses is essential to ensure the fire resistance of these timber structures. By doing so, this work also contributes to cultural heritage conservation and to more sustainable construction in alignment with the fulfilment of United Nations 2030 Agenda¿s eleventh goal: "Sustainable cities and communities".The authors wish to express their gratitude to the Spanish Ministry of Economy, Industry and Competitiveness for the funding provided through Project BIA 2014-59036R.

Wiener modelling and model predictive control for wastewater applications
No full textThe research presented in this paper aims to demonstrate the application of predictive control to an integrated wastewater system with the use of the wiener modeling approach. This allows the controlled process, dissolved oxygen, to be considered to be composed of two parts: the linear dynamics, and a static nonlinearity, thus allowing control other than common approaches such as gain-scheduling, or switching, for series of linear controllers. The paper discusses various approaches to the modelling required for control purposes, and the use of wiener modelling for the specific application of integrated waste water control. This paper demonstrates this application and compares with that of another nonlinear approach, fuzzy gain-scheduled control
Entre o aggiornamento e a solidão: práticas discursivas de D. Antônio Mazzarotto, primeiro bispo diocesano de Ponta Grossa - PR (1930-1965)
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-graduação em HistóriaAnálise das práticas discursivas de D. Antonio Mazzarotto, primeiro bispo da Diocese de Ponta Grossa PR (1930-1965). D. Antonio nasceu em 1890, em Santa Felicidade (PR), e foi ordenado em 1914. Ainda um jovem sacerdote, angariou fama de erudição, eloqüência na pregação e empenho na direção espiritual da juventude. Desde a época do seminário até 1965, quando renunciou, sua produção escrita foi incessante. Voltou-se especialmente para a escrita de cartas pastorais, publicadas todo dia 23 de fevereiro e nelas veiculou o programa da Restauração Católica para a diocese. Em Ponta Grossa, locus de disputa de projetos múltiplos e desiguais, D. Antonio representou o esforço unificador e normatizador da instituição católica. Bispo exemplar e inserido numa determinada tradição espiritual suas representações discursivas explicitam simultaneamente a influência da formação e os sentidos singulares da mensagem anunciad
The economy and archaeology of European-made glass beads and manufactured goods used in first contact situations in Oregon, California and Washington.
No full textThis thesis examines the role played by European-made glass beads and other manufactured goods in first contact of Europeans with Native American Indian populations in Oregon, California and Washington. Utilising both the historical and archaeological record, the activities of the Spanish in Alta California, the Russians in Northern California, the Lewis and Clark expedition and the Pacific Northwest Coast companies are examined, highlighting their use of beads in gift giving and exchange with the Indians. The sources of the large volume of glass beads are presented and their method of manufacture discussed. The way In which different European nationalities and organisations progressed geographically and in the intensity of their interactions with the native populations is reflected in the archaeological assemblages, whilst processes of exchange and the use of trinkets such as beads in subjugation and pacification are clarified by study of the historical sources. Different European groups used such materials through the mission system, by pacification of groups to ensure access and safe passage and by the fur companies use of the beads as items of exchange for pelts of otters and other animals. The native Indian groups showed different preferences for specific coloured beads which then became part of their own wealth base and exchange system. The effects of such transactions, whether used deliberately as a form of subjugation or inadvertently as barter items, was to transform the economic systems of the native populations and specifically the way In which conspicuous consumption was carried out in potlatch ceremonies. The effect of both the introduction of new material items and the novel form of economic transactions bolstered other effects of the Europeans which transformed Native American cosmology and society permanently
The ecology and control of cutaneous Leishmaniasis vectors in the sub-Andean mountainous zone of Huila department, Colombia
No full textThis thesis describes a series of studies
designed to improve
our understanding
of
the
transmission cycle of cutaneous leishmaniasis (CL) in the
coffee-growing
sub-Andean
region of Huila department and to explore
the
use
of
insecticide treated
bednets
as
an
alternative control measure to the current policy of
house
spraying.
The thesis
is divided
into six chapters, including four results chapters.
Chapter 1
reviews
the
public
health
importance of CL in the Andean region,
in
Colombia
and
in
Huila
department;
explores
the possible risk of CL in coffee plantations
at regional,
departmental
and
municipal
levels; and presents a brief summary on
control
strategies
in the
Andes,
Colombia
and
Huila. Chapter 2 describes an exploratory study
in
seven representative
areas within
the sub-Andean region (1000
-
2000 m a.s.l. )
of
Huila
department
designed to
identify
possible CL vectors and the ecological
determinants for their
distribution
and
abundance. The study helps to: (i) explain
the
current
distribution
of
CL in
Huila
department; (ii) identify the boundaries of
the
epidemic
area;
and
(iii) identify
new
areas
of potential risk for the disease which
should
be
considered
for
monitoring
or
prevention programs. The main findings were:
(1) the
CL foci
of
Huila
was
identified
geographically; (2) Lutzomyia longiflocosa appears
to
be the
principal
sandfly
vector,
having a narrow ecological niche
defined largely
by
altitude,
temperature
and
a
preference for a well structured forest or
forest-like
habitat
(i.
e.
traditional
coffee-
growing area); (3) there was no evidence
for
complete
adaptation
of
L. longiflocosa to
intensive coffee plantations; and (4) L.
nuneztovari
is
a generalist
species
which
has
at
most a limited secondary vectorial role
in this
region.
Chapter
3
describes
a
cross-sectional study at household level in three
villages
(267
houses)
designed to
(i)
identify environmental risk factors for the
suspected
vectors
and
(ii) identify
demographic, environmental and entomological risk
factors for
disease.
The
main
findings were: (1) stronger evidence incriminating
L. longiflocosa
as
the
main
vector,
and confirming the less important role
of
L.
nuneztovari,
(2) the
detected
risks
confirmed the feasibility of the use of
insecticide treated
bednets
(ITNs)
as a
control
measure for CL. Chapter 4 describes a
series of
field
studies
to
evaluate
the
use of
lamdacyhalothrin treated bed nets as an
alternative
control
measure
(to
house
spraying)
for CL within the study area: (1) the entomological efficacy
of
ITNs
was
tested
under
controlled conditions; (2) the entomological effectiveness
(measured
indirectly
by
indoor CDC light traps) of ITNs and
house
spraying
were
both
measured
in
a
V household-based intervention trial; (3) the
reliability
of
light traps
as an
indicator
of
indoor sandfly exposure (in the previous study)
was
tested
by
comparison
with
indoor
human landing catches; and (4) field bioassays
were
used to
measure the
residual
lethal
effect of the insecticide up to 4 months after
both interventions
were
implemented in the
effectiveness trial. Together, the efficacy and effectiveness studies
showed
that ITNs
reduce L. longiJlocosa indoor human landing
rates,
blood feeding
success,
and
Human
Blood Index. The effects of house spraying were unclear, as
the
reduction
in
sandfly
numbers (fed and unfeds) observed
in light traps
in
sprayed
houses
was not
reflected
by
any reduction in human landing catches.
Chapter
5
describes
a questionnaire
study of
the inhabitants in the epidemic area to
evaluate
their
knowledge,
attitudes and
practices
in relation to sandfly and CL control
in
Huila.
The
study
showed
that
(i)
bednets
were
widely used, but less so amongst the poorest
households,
and
(ii)
nets
were
commonly
used to reduce sandfly nuisance rather than
reduce
the
risk
of
CL. However
knowledge
of sandfly involvement in CL transmission was
positively
associated
with
net usage.
This information should help inform the
design
of
future ITN
campaigns
in the
region.
Finally, Chapter 6 summarises and
integrates the
main
findings
of
the four
results
chapters, recommends the provision of
ITNs to
replace
house
spraying
for
CL
control
in Huila, and proposes future studies which should
be
prioritised

No full textThe water resources of the united Arab emirates: a comprehensive empirical appraisal of their status and management
No full textThe expansion in the cultivated area since the mid-1970s, and the eventual high demand for water, have taxed the groundwater resources of the Emirates to the limit. The annual groundwater abstraction by agriculture, based on average discharge measurements for the present study, is put at 2556 MCM/a. while the overall groundwater volume abstracted by all sectors is 3359 MCM/a; the total output from all the desalination plants at 300 MCM/a, and that from the wastewater recycling plants at 80 MCM/a. With the population for 1989 standing at .1.8 million, the per capita consumption is 2116 m(^3)/a, which is close to that for the United States of America (2300 m(^3)/a ).The water resource problem is common to all the Gulf Cooperation Council states. In the Emirates, as in all the neighbouring countries, the problem is embodied in the paradox of expansion in extensive agriculture despite the depleting groundwater resources. There is also the absence of a water policy, a plan or coherent water resource management. For the last aspect, there is a lack of indigenous expertise with the necessary knowledge to monitor water resources and guide their development. The 8-fold increase in the cultivated acreage from 12,894 ha. in 1973 to 96,704 ha. in 1988, the 10-fold increase in population from 179,100 in 1968 to 1,748,804 in 1988, the continuously stable high cost of food imports during the past decade of above 3.0 billion dirhams ($ US 0.8 billion) a year and the 22-fold increase in water consumption from 172 MCM/a in 1968 to 3659 MCM/a. in 1989, sum up the water resource problem of the Emirates. As a result, water-tables have been receding continuously, groundwater salinity rising both in inland and coastal aquifers, and the shallow fresh water aquifer in the Quaternary deposits has been depleted in many parts of the piedmont (gravel) plains. Given this critical state of the groundwater resources, the preclusive cost of desalinated water to its application to agriculture and the ill-advised outlets to which every possible water resource developed is put, an urgent rethinking of water policies and development is vital. Such rethinking should set water-related priorities right, should resist all temptations, for reasons of national security, to imports of foreign water, and should be within the context of well-intentioned efforts towards achieving food security, through specialized agriculture, as much as is naturally possible
