  • Some water moves through the skin of mammals by insensitive diffusion. Most of the water, which passes through the skin, however, does so in the form of active sweating. Larger mammals usually sweat to dissipate heat. Among the domestic species, both camels and cattle have adopted this mechanism. A characteristic of the camel is that there is no copious flow of sweat or obvious wetting of the hair. The evaporation takes place at the surface of the skin and not at the extremities of the hair. The latent heat of evaporation is therefore drawn from the skin rather than from...

  • The skin plays an important role in maintaining the integrity of the living organism while allowing the interaction of the organism with its environment. To fulfill these functions, mechanical stability is as important as flexibility. The mechanical properties of skin are very diverse depending on the anatomical location, and they evolve throughout life from the fetus to old age. Both genetic and acquired skin diseases modify skin biomechanics, as do intrinsic and photoaging.

  • There are several reasons that may explain why the prevalence of heart failure is increasing: ageing of the population, the success in prolonging survival in coronary patients, and the success in postponing coronary events by effective prevention in those patients at high risk or those patients who have already survived a first event (secondary prevention) (Senni et al, 1999). Advances in medical therapy have resulted in improved survival in patients with moderate and severe heart failure, but the prognosis for end-stage heart failure patients still remains poor.

  • The modular producer cell lines present several advantages: they are safer since integration of the vector within the packaging cell line was identified, the duration of the entire development process is much reduced as there is no need for screening and, in addition, production conditions are favorable due to the possibility of pre-adaptation of the master cell line to culture conditions and media. Thus, therapeutic virus production from bench to bedside becomes safer, faster, and cheaper (Coroadinha et al. 2010)....

  • Creating markets for SME business development services does not mean relying exclusively on ‘for profit’ support. Rather, it means recognising that intervention may be justified when it helps to articulate SME needs more clearly, so that a clear demand for certain services is created which markets can provide. It also requires ensuring that commercial suppliers of support are equipped to deal with that demand.

  • Other than this, automation and optimization of production engineering was attempted in various fields. Okumoto et al. (2005D) optimized the block allocation on the assembly area using simulated annealing method. Wibisono et al. (2007) optimized block division planning using genetic algorithm and product model. Universal Shipbuilding Corporation (2008) developed a high performance NC Printing Machine, which enables fast printing irrespective of the number of characters and lines to be printed.

  • Some of those shareholders kept a close watch on the Fund’s holdings and noticed a large position in broker Lehman Brothers. These investors—sensing that the brokerage firm might be in trouble— decided to take their money out of the fund. To meet their redemption requests, the fund sold other securities—with the unfortunate result that the problematic Lehman securities became an ever-larger portion of the remaining assets.

  • The Reschovsky and Staiti study [28] interviewed both patients and physicians, and provides considerable insight regarding differences in physical accessibility across the urban-rural continuum. The nationally representative survey was fielded in urban, suburban, and remote rural regions. Persons in remote rural regions had significantly longer travel times to see physicians and specialists than persons in metropolitan areas (2 minutes longer to see a physician and 34 minutes longer to see a specialist).

  • Remote Control Transmitter: (refer to the schematics and block diagram on p.31 as needed) When the levers in the Remote Control Unit are pushed electrical contacts are made connecting the 9V battery power to the transmitter and indicating which commands the user wants sent to the car. Forwards/Backwards and Left/Right commands are controlled by different levers and use different sets of electrical contacts that are used to encode a sequence of electrical pulses; the number of pulses depends on which command is being sent.

  • The most significant audience for which Hollywood failed to cater in the immediate post-war decades, and which created the basis for some of the most important strains of independent production, was the youth audience. Hollywood was very slow to respond to demographic and other social changes during the 1950s and 1960s that created a large audience receptive to material targeted at teenage viewers.

  • We contacted Planned Parenthood centers to determine which of their clinics in the county (two clinics each were chosen for Bexar County and Dallas County) saw the greatest number of WHP clients in 2011. Based upon the assumption that clients who attend those Planned Parenthood clinics would seek care at providers in the same proximate area, we identified non-PPFA providers within 30 miles of the chosen Planned Parenthood clinics and chose four non-PPFA providers who served the largest number of WHP clients in 2011 for interviews.

  • In the eight years since publication of the first edition, enormous progress has been made in the field of skin imaging and analysis. Because of the broad array of new methods now available to the research scientist—and more and more to the clinically- oriented dermatologist—we were able to widen the scope of this book from the skin surface to the entire skin. This is also reflected in the change of the volume title, Bioengineering of the Skin: Skin Imaging and Analysis. Hence, this second edition is a major revision of the first edition, with more than 30 new chapters added....

  • Carbon monoxide is a clear, odourless gas produced by the incomplete combustion of organic compounds. It reduces the blood’s capacity to carry oxygen. CO combines selectively with haemoglobin (the oxygen transport protein in red blood cells) to form carboxyhaemoglobin. CO impairs perception and judgment at low levels. Effects worsen as CO levels rise, leading ultimately to convulsions and coma at high concentrations. The CO provisions of the ambient air NEPM are based on evidence that a carboxyhaemoglobin threshold of 2.

  • Another service is the grading of products by recognized standards of quality. Grading helps farmers get fair prices for their products. It also permits commercial buyers to make purchases of such products as milk, butter, eggs, and meat on a basis of quality and price. Wholesaling and retailing, two essential services, are performed on the widest scale possible. They reach every community.

  • More companies are proving it is possible to make money and actively help to slow the degradation of the planet for future generations. Within these companies, the push for change comes from the top—it’s all about leadership. UTC Power has great success working with organizations whose leaders are visionary about how their business affects the environment. They are concerned about where their companies need to be 3 0 or 40 years down the road. It’s the vision of the leadership that moves them toward using power solutions like ours.

  • Transport will play a critical role in delivering the CO2 emissions cuts needed to meet global political cli- mate change targets. The world’s car fleet is expected to triple by 2050, with 80% of the growth in rapidly developing economies. At the same time the car manufacturing industry is facing huge difficulties in the economic recession. We have to find ways to reconcile legitimate aspirations for mobility, an ambitious reduction in CO2 from cars worldwide, and global economic recovery.

  • A common approach to estimating node positions is direct mea- surement or triangulation against landmarks in the immediate one- hop vicinity. Active Badge [24] relies on the closest infrared re- ceiver to locate specialized beacons carried by tracked assets. RADAR [19] relies on a centralized database of signal fingerprints from land- marks obtained at all locations and orientations to localize a node. Lorincz andWelsh [14] propose a similar RF fingerprint-based node localization technique that relies on strength signatures and a dis- tributed database.
