  • This book should be of interest to scholars, researchers, students, and practitioners alike. Scholars, researchers, and students of personal relationship development will recognize in this book the first serious attempt in over 40 years to do a large-scale, longitudinal study of premarital factors that predict premarital breakup and marital quality; they should also appreciate our attempt to develop a theoretical rationale for predicted paths and to test those paths with the best available statistical tools.

  • This handbook emphasizes the use of synthetic membranes for separations involving industrial or municipal process streams. Little will be said concerning the use of membranes in medical applications as in artificial kidneys or for controlled drug release. Most of the membrane processes are pressure driven. The notable exception to this is electrodialysis (ED) by which ions are separated under the influence of an electric field. In addition, the chapter on coupled transport covers processes which are driven under the influence of a concentration gradient....

  • When the field of microfluidics emerged in the early 1990s, it was primarily focused on the development of analytical microdevices. Since then, microfluidics has expanded its influence into virtually every branch of science and engineering. There are many driving forces behind this explosive growth. To name a few: • Scaling properties afforded by miniaturization are desirable for many applications. For example, enhanced mass transfer and heat dissipation enable faster chemical separations without sacrificing separation performance....

  • In the MEMS industry, systems for deep reactive-ion etching (DRIE) utilize fast pumping, fast-response mass-flow controllers inductive coupling of power, and heated chamber and pump lines that are critical to achieve reliable etch rates. In contrast, we have achieved 8:1 aspect-ratio PhC structures with 62nm vertica membrane walls using a standard reactive-ion etching process based on a sidewall passivation processes. In the remainder of this section we discuss this fabrication process.

  • The study of catalytic membranes and membrane reactor processes is a multidisciplinary activity, which in recent years has attracted the attention of scientists and engineers in a number of disciplines, including materials science, chemistry and biology, and chemical and biochemical engineering.

  • B Semi-colon (;) We can use a semi-colon between two separate statements which are linked in meaning. Melanie is a very kind person; she visits David in hospital every day. We could also use a full stop here. C Colon (:) We can use a colon before an explanation or before a list. Vicky felt nervous: she hated the dark. There wasn't much in the fridge: a couple of sausages, some butter, half a bottle of milk.

  • In the past few years we have observed an interesting mutual interest of two fields of research and development in each other. Life sciences area researchers discovered the opportunities offered my micro- and nanotechnology, while people from the microfluidics and BIOMEMS area discovered the application potential of these technologies in cell biology. Unfortunately, these two research communities share little in common: they read and publish in different scientific journals, have incompatible jargons, attend separate conferences, and have a different scientific approach and culture.

  • Data is increasingly generated by instruments that monitor the environment – telescopes looking at the heavens, DNA sequenc- ers decoding molecules, bar-code readers watching passing freight-cars, patient monitors watching the life-signs of a person in the emergency room, cell-phone and credit-card systems look- ing for fraud, RFID scanners watching products flow through the supply chain, and smart-dust sensing its environment. In each of these cases, one wants to compare...

  • With Oracle Real Application Clusters (as with any other Oracle database) the Oracle Instance (the processes and memory structures allocated on a server to allow access to the data) is de-coupled from the Oracle Database (the physical structures residing on the storage, which actually hold the data. These structures are commonly known as ‘datafiles’). However, a clustered database (using more than one instance) differs from a single instance database in a way that the database can be accessed by multiple instances concurrently.

  • This is very convenient and the ready access to the Internet in all first-world countries, coupled with the cost savings from closing bank branches, is driving the deployment and adoption of these services. Purely online transactions, however, lead to increased risk. None of the normal safeguards of real-world transactions are present. Conversely, risk to the criminals is a lot lower (the attacker can be in a completely separate jurisdiction from all the other parties in the transaction) and the retailer sees nothing but a faceless, nameless connection providing card details.

  • An attractive property of attribute-value grammars is their reversibility. Attribute-value grammars are usually coupled with separate statistical components for parse selection and fluency ranking. We propose reversible stochastic attribute-value grammars, in which a single statistical model is employed both for parse selection and fluency ranking.

  • The rotor subunitc of the A1AOATP synthase of the hyperthermophilic archaeon Pyrococcus furiosuscontains a conserved Na + -binding motif, indicating that Na + is a coupling ion. To experimentally address the nat-ure of the coupling ion, we isolated the enzyme by detergent solubilization from native membranes followed by chromatographic separation tech-niques.

  • Insulin-like peptide 3 (INSL3), which is primarily expressed in the Ley-dig cells of the testes, is a member of the insulin superfamily of peptide hormones. One of its primary functions is to initiate and mediate des-cent of the testes of the male fetus via interaction with its G protein-coupled receptor, RXFP2. Study of the peptide has relied upon chemical synthesis of the separate A- and B-chains and subsequent chain recombi-nation.
