  • 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.

  • 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 structures.

  • 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 reconnect.

  • 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.

  • 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.

  • 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 mortgage lending. 11 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...

  • 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.
