  • This book is intended as a companion to Thermodynamics and Kinetics for the Biological Sciences, published in 2000.These two books are based on a course that has been given to first-year graduate students in the biological sciences at Duke University.These students typically do not have a strong background in mathematics and have not taken a course in physical chemistry. The intent of both volumes is to introduce the concepts of physical chemistry that are of particular interest to biologists with a minimum of mathematics.

  • Atomic Absorption Spectroscopy is an analytical technique used for the qualitative and quantitative determination of the elements present in different samples like food, nanomaterials, biomaterials, forensics, and industrial wastes. The main aim of this book is to cover all major topics which are required to equip scholars with the recent advancement in this field. The book is divided into 12 chapters with an emphasis on specific topics.

  • The probiotic bacteria must be viable to affect the health, but the non-viable bacteria could also affect the immunological status of the host. It is believed that the arrival of probiotic bacteria with food to different parts of intestine can increase probiotic bacteria adherence and the rate of colonization. Food products may contain many forms of probiotic bacteria, including culture concentrate that is added to a food (dried or deep-freeze form), the fermented or non-fermented food products, and dietary supplements in the form of drug products-powder, capsules or tablet.

  • The characteristics lines in X-ray spectra result from electronic transitions between inner atomic orbitals. The X-ray spectra for most heavy elements are much simpler than the UV/Vis spectra observed in ICP-OES, for example. (Only a few lines!!!) Big difference between X-ray and UVVis: The radiation is ionizing, and doesn’t just excite electrons to higher levels. Moseley’s law: Predicts the basic relationship of atom number and the frequency of the characteristic lines

  • This book provides readers with a clear progress to theoretical and observational astrophysics. It is not surprising that astrophysics is continually growing because very sophisticated telescopes are being developed and they bring the universe closer and make it accessible. Astrophysics Book presents a unique opportunity for readers to demonstrate processes do occur in Nature.

  • Since the advent of magnetic resonance (MR) imaging, systems with amagnetic field intensity of 1.5 tesla (T) have been deemed the gold standard for different clinical applications in all body areas. Ongoing advances in hardware and software have made theseMRsystems increasingly compact, powerful and versatile, leading to the development of higher magnetic field strength MRsystems (3.0 T) for use in clinical practice and for research purposes. As usually occurs with a new technology, 3.0 T MR imaging units will probably follow the same development trends in the years to come....

  • Deviations from Beer’s law (i.e. deviations from the linearity of absorbance vs. concentration): – Intermolecular interactions at higher concentrations – Chemical reactions (species having different spectra) – Peak width/polychromatic radiation Beer’s law is only strictly valid with single-frequency radiation Not significant if the bandwidth of the monochromator is less than 1/10 of the half-width of the absorption peak at halfheight.

  • The emission factors of the 14 most abundant VOCs on sequential cold weather sampling dates (January 17 and March 12, 2003) are compared in Table 4. Indoor and outdoor temperatures and percent RHs were approximately equivalent between these dates (Table 1). However, the January air change rate was 0.58 h-1 versus 0.31 h-1 in March, likely due to the difference in wind conditions. Within both the aldehyde and the terpene hydrocarbon chemical classes, the ratio of the emission factor at the lower air change rate to the emission factor at the higher air change rate was near...

  • Wireless communications offer organizations and users many benefits such as portability and flexibility, increased productivity, and lower installation costs. Wireless technologies cover a broad range of differing capabilities oriented toward different uses and needs. Wireless local area network (WLAN) devices, for instance, allow users to move their laptops from place to place within their offices without the need for wires and without losing network connectivity. Less wiring means greater flexibility, increased efficiency, and reduced wiring costs.

  • Recent policy attention and research have focused on children's school commuting. Concerns include children's health and safety, traffic congestion, environmental impacts of transportation, and parents' time chauffeuring children. Popular responses aim to increase rates of commuting by bicycle and walking (Rosenthal, 2009), but rarely do these initiatives directly account for other policies, such as school choice, that also impact school transportation.

  • A recent article in this journal, “The child health/family income gradient: Evidence from England” (Alison Currie, Michael A. Shields and Stephen Wheatley Price, 2007) argues that income gradients in the health of English children differ from those observed in either the US or Canada. Using data from the 1997 to 2002 Health Survey for England (HSE), Currie, Shields and Wheatley Price (CSW) conclude that English health gradients in income are small and increase little as children grow older.

  • EPR spectroscopy, performed after site-directed spin-labeling, was used to study structural dynamics in a cold-adapted alkaline phosphatase (EC 3.1.1.1). Differences in the structural environment of six spin-labeled side chains allowed them to be classified (with reference to previously obtained mobility maps) as belonging to loop positions (either relatively surface exposed or in structural contact) or helix positions (surface exposed, in contact, or buried).

  • Thea-phycoerythrocyanin subunits of the different phy-coerythrocyanin complexes of the phycobilisomes from the cyanobacterium Mastigocladus laminosusperform a remarkable photochemistry. Similar to phytochromes – the photoreceptors of higher plants – the spectral pro-perties of the molecule reversibly change according to the irradiation wavelength. To enable extensive analyses,the protein has been produced at high yield by improving purification protocols.
