Welcome to the discipline of building services engineering. You will find that it
extends beyond the confines of this text, which concentrates on some of the ‘wet
services’ within the building envelope. Part of Chapter 1, however, looks at the
building and the way it behaves when it is intermittently heated, as it is important
for you to select the plant and design the system that will best suit the building
and its use. It is assumed that you have some knowledge of building services.
Plants are sessile organisms and as such must have mechanisms to deal with both abiotic
and biotic stresses to ensure survival. The term “abiotic stress” includes many stresses
caused by environmental conditions such as drought, salinity, UV and extreme
temperatures. Due to global climate change it is predicted that abiotic stresses will increase
in the near future and have substantial impacts on crop yields (Intergovernmental Panel of
Climate Change; http://www.ipcc.ch).
A new class of rugged fiber optic connectors has been introduced to speed
residential connection in Fiber-To-The-Premises (FTTP) cabling networks. The
connectors are strategically located in the distribution network to facilitate
service connection, maintenance and reconfiguration of subscriber services.
Connectors are typically staged at the street outside a residence to facilitate
easy access and connection to the residence at a later date.
Sugars play important roles as both nutrients and regulatory molecules
throughout plant life. Sugar metabolism and signalling function in an intri-cate network with numerous hormones and reactive oxygen species (ROS)
production, signalling and scavenging systems.
Taking military barracks wastewater treatment as an example, this paper presents a new concept design of a modified DEWATS system with both the horizontal subsurface constructed wetland and aquatic plants pond. Results show that this process in treating the military barracks area wastewater have many advantages such as low operation cost, simple operation and maintenance, and the effluent could meet "the urban wastewater treatment plant pollutant discharge standard" for first level Class A.
As rates of deforestation and land degradation, and losses of biodiversity and
ecosystem services, continue to rise globally, the international community is faced
with the challenge of finding land use interventions that can mitigate or reduce the
impact of these environmental issues. Agroforestry, the integration of trees in farming
systems, has the potential for providing rural livelihoods and habitats for species
outside formally protected lands, connecting nature reserves, and alleviating resourceuse
pressure on conservation areas.
Does this mean that differences in genetic diversity levels will have predictable
ecological consequences? The answer is no, because only one portion of genetic diversity is
connected to ecological factors, i.e. adaptation. Ecological adaptation is a significant factor
for example, in range expansion of plant species. Plants with different genotypes conferring
the highest levels of fitness are expected to survive and reproduce better, shifting the gene
pool over time towards higher frequencies of the alleles making up the more successful
genotypes (Ward et al., 2008).
The need for protection against the effects of explosions is not new. The use
of explosive weaponry by the military necessitated resistive entrenchments ages
ago. Industrialization of our societies well over a century ago meant that we
intended to manufacture, store, handle, and use explosives in constructive ways.
To support these military and industrial purposes, a relatively small group of
designers have worked to devise ways to strengthen the blast resistance of our
Events are continuously generated and consumed by clients within the system. Clients have
intermittent connection semantics. Clients can be present in the system for a certain duration
and be disconnected later on. Clients reconnect at a later time and receive events, which they
were supposed to receive in their past incarnations as well as events that they are supposed
to receive during their present incarnation. Clients issue/create events while in disconnected
mode, these events would be held in a local queue to be released to the system during a
Our goal in writing this book was to describe
why weeds occur where they do. We have
made no attempt to discuss their management
and control: there are excellent texts
available for that. Rather, we think that students
should understand how and why
weeds fit into their environment. This text
presents ecological principles as they relate
to weeds. Ecology is central to our understanding
of how and why weeds invade and
yet there are few books that make this connection.
That is the niche we hope to fill.
The research is designed for developing the pilot small-scale clean development
mechanism bundled project activities in Vietnam electricity/ energy sector. Its overall
purpose is to assess the potential of rice husk - fuelled bio-power development projects
in Mekong delta.
Numerous U.S. REITs and other institutions have invested in real property connected to
maquiladoras, retail development and tourism. This trend should persist because Mexico is ripe for
continued investment. With respect to retail development, for example, there are fewer than 1,000
malls and shopping centers in Mexico, which has a population of approximately 110 million
people. In comparison, there are more than 102,000 malls and shopping centers in the U.S., which
has a population of approximately 306 million people.
In 1821, Mr. Seebeck thermoelectric phenomenon when connecting copper wire and iron together. A joint dipped in ice water, the remaining joints dipped in boiling water. The temperature difference between the two splice shift of electrons to generate electricity.
At the end of the 1980s, more than 1,000 savings & loan institutions in the United States
were threatened by insolvency due to financing with divergent maturity dates in
connection with high interest rates for depositors but comparatively low rates on
In 1989, the Resolution Trust Corporation (RTC) – a bad bank –
was founded. The RTC was set up with government funding and to a limited extent with
money from private investors. Between 1989 and 1995, the RTC took over 747 bankrupt
S&Ls with a book value of 394 billion dollars. The S&L bailout cost US taxpayers...
The sensory networks that transduce information starting with the capture of a photon into
a suite of downstream responses are well known. Historically these pigments were
postulated to control various aspects of plant growth and development, particularly
germination, phototropic movements and the transition between vegetative and
reproductive growth. Long before the genes and proteins were identified and characterized,
a tremendous body of work produced evidence of their activities and effects on physiology.
Light quality effects on germination were examined by Lewis H.
The castles of the great landowners have been so often described that there is no need to do this again. The popular idea of a baron of the Middle Ages is of a man who when he was not fighting was jousting or hunting. Such were, no doubt, his chief recreations; so fond was he of hunting, indeed, that his own broad lands were not enough, and he was a frequent trespasser on those of others; the records of the time are full of cases which show that poaching was quite a fashionable amusement among the upper classes. But...
While the above-described uses (and potential uses) of social media by insurance companies are
important to note, it must be pointed out there is another side of the proverbial coin to social media in
insurance. A not-insignificant number of insurance companies — concerned about the novelty of the
medium, the lack of explicit regulatory and legal guidance, and very real practical and technical issues —
have either banned the use of social media outright or taken an approach of benign disregard relative to
the use of social media in connection with their...
Financial incentives are an important tool that can help individuals and businesses overcome
the barrier of high initial equipment costs for these technologies. But, to be effective, these
incentives should be considered as one component in a comprehensive approach to creating a
We propose a new design for highly concurrent Internet services, which
we call the staged event-driven architecture (SEDA). SEDA is intended
to support massive concurrency demands and simplify the construction
of well-conditioned services. In SEDA, applications consist of a
network of event-driven stages connected by explicit queues. This architecture
allows services to be well-conditioned to load, preventing
resources from being overcommitted when demand exceeds service capacity.
We deﬁne the data placement problem for a P2P system as follows. Assume we are given a set of cooperating nodes
connected by a network (typically, but not necessarily, the Internet) that has limited bandwidth on each link. Nodes
know about and exchange data with a collection of participating peers, and they may serve any or all of four roles. The
ﬁrst of these is a data origin, which provides original content to the system and is the authoritative source of that data.
