  • Through the aid of a compiler, a program written in a computer language, such as C++, is turned into machine code, which is executed on the computer. However, going from an idea to a program that works successfully takes a lot of time and effort. It may take several rewrites of code to get the program to work correctly. To accomplish this, students must learn a disciplined approach to organizing the code and learn how to trace their programs.

  • Journalists are highly dependent upon individuals and organizations (including government officials, agencies and nongovernmental organizations) for a steady and reliable flow of newsworthy information. This flow of information makes news production more predictable, efficient and profitable. When this flow is blocked (for example, when traditional news sources are unavailable for comment or do not respond within the journalist’s deadline), journalists are more likely to seek other sources, which may be less authoritative, accurate, responsible or reliable....

  • While it has been demonstrated that these materials have good sensitivity to polar VOCs, such as alcohols and acetone, 11,12 their rather poor response to nonpolar analytes has been viewed as a major drawback. In this report, we explored two ways to improve the sensor performance of regioregular polythiophene. The first approach is to add a second polymer at the end of the polythiophene chain to form a block copolymer. This second polymer interacts with the analytes in different ways, thus adding another dimensionality to the sensing response of the material.

  • The average cost to bring to market a so-called block-buster drug is currently estimated at $895 million (EFPIA, 2002). Obviously firms who spend that kind of money need to recoup their costs. Furthermore industry analysts point out that Big Pharma under pressure. It needs to expand sales of blockbuster drugs since there are fewer drugs in pipeline. In order to sustain current levels of growth, firms would need to introduce one new product each year that would sell $4.9 million for each 1 to 1.5 per cent it has of the world pharmaceutical market. “A company the size of the...

  • Regioregular polythiophene-based conductive copolymers with highly crystalline nanostructures are shown to hold considerable promise as the active layer in volatile organic compound (VOC) chemresistor sensors. While the regioregular polythiophene polymer chain provides a charge conduction path, its chemical sensing selectivity and sensitivity can be altered either by incorporating a second polymer to form a block copolymer or by making a random copolymer of polythiophene with different alkyl side chains.

  • Yet without good metrics and tangible evidence of impact, the majority of the executives in the survey said their organizations cannot take social media efforts seriously. And that poses a challenge for companies, says Avinash Kaushik, Google’s Analytics Evangelist and author of Web Analytics 2.0, because social media can build up a great deal of data, but not necessarily generate great insights that translate into action and then more customers and sales.

  • The RRL also conducts analysis of r-value or vaccine matching of field isolates in comparison with relevant vaccine strains. In terms of serology, the RRL routinely uses liquid phase blocking (LP) and non structure protein (NSP) ELISA. It has been involved in several validation tests conducted for NSP ELISA under the IAEA Project. In addition, the RRL routinely produces and supplies the FMD diagnostic reagents to laboratories both within Thailand as well as SEAFMD countries.

  • Crystalline arrays of protein or glycoprotein subunits forming surface layers (S-layers) are the most common outermost envelope components of prokaryotic organisms (archaea and bacteria). The wealth of information on the structure, chemistry, genetics, morphogenesis, and function of S-layers has revealed a broad application potential.

  • Caveolae are plasma membrane invaginations with several functions, one of which appears to be to organize receptor mediated signalling. Here we report that in primary human subcutaneous adipocytes the insulin receptor was localized to caveolae by electron microscopy/immunogold detection and by isolating caveolae from plasma membranes.

  • As I walked the few blocks to the examination room, it occurred to me that the city authorities had probably gone through a similar analysis. The frequency of their inspection of parked vehicles and the size of the penalty imposed on violators should depend on their estimates of the type of calculations potential violators like me would make. Of course, the first question I put to the hapless student was to work out the optimal behavior of both the offenders and the police, something I had not yet done....

  • Chapter 3 - Cells: The living units (part a). Just as bricks and timbers are the structural units of a house, cells are the structural units of all living things, from one-celled “generalists” like amoebas to complex multicellular organisms such as humans, dogs, and trees. The human body has 50 to 100 trillion of these tiny building blocks. This chapter focuses on structures and functions shared by all cells.

  • Module 13 - Secondary storage structure. In this chapter we describe the internal data structures and algorithms used by the operating system to implement this interface. We also discuss the lowest level of the file system the secondary storage structure. We first describe disk-head-scheduling algorithms. Next we discuss disk formatting and management of boot blocks, damaged blocks, and swap space. We end with coverage of disk reliability and stable-storage.
