Geology -- Guatemala -- Lake Atitlan area; Volcanism -- Guatemala -- Lake Atitlan area; Calderas -- Guatemala -- Lake Atitlan area.
Geological mapping, petrological and geophysical studies in the lake Atitlan area, Guatemala, have revealed four distinct periods of stratovolcano growth, each followed by major silicic eruptions and caldera collapse. The first period (12 - 11 my...

Polynomials. Finite fields (Algebra). Algebraic functions. Number theory.
The ring of univariate polynomials over a finite field shares many foundational arithmetic properties with the ring of rational integers. This similarity makes it possible for many problems in elementary number theory to be translated 'through the...
In this thesis, we consider several problems relating to cyclic subgroups of the group [mathematical equation]. Each element of [mathematical equation] has a unique representative in one of the two intervals [mathematical equation] and...
Recent technological advances have fostered the emergence of Wireless Sensor Networks (WSNs), which consist of tiny, wireless, battery-powered nodes that are expected to revolutionize the ways in which we understand and construct complex physical...
Understanding trace element homeostasis in plants has a direct impact on global health. Much of the developing world suffers from nutrient deficiencies, and subsists on a plant based diet often lacking bioavailable nutrients like iron and zinc. At...
The synthesis of macrocyclic tetrapyrroles continues to be an area of vigorous research due to their application to a wide range of fields spanning the physical sciences. Only recently have general syntheses for the reduced systems, such as...
In the nervous system, neuronal communication relies critically on the function of membrane ion channels. One of these is the voltage-gated sodium channel (VGSC), which is essential for the generation and propagation of action potentials in...
Arsenic is implicated in numerous human pathologies, including cancer and several forms of liver disease. One contributing mechanism may involve alterations of CYP levels by arsenic. CYP3As are the most abundant CYP proteins in human liver and...
Synthetic electrochemistry is a rapidly growing area of interest within the synthetic community, although it is far from being a routine technique. Despite the fact that many oxidative and reductive conversions are known, electrochemical methods...
Antennas (Electronics); ; Thermotherapy. ; Cancer -- Treatment.
Engineers have devised many techniques by which to raise the temperature of a cancer tumor 8 degrees above body temperature. Such treatment is called hyperthermia; experiments in vitro suggest it may be an effective adjunct to standard radition...
Metal ions. Binding sites (Biochemistry) -- Thermodynamics. Metalloenzymes. Cellular control mechanisms. Thermometric titration. Calorimetry.
The chemistry of biology is complex and there is a great deal that is not understood. A fundamental understanding of biochemical reactions is important to aid in the identification of undiscovered reactions and is critical to fully appreciate the...
Metal ions confer structural stability and reactivity to a large number of proteins that use the amino acids histidine (His) and cysteine (Cys) to form stable metal-ligand complexes. The stability of metal-His and metal-Cys interactions and their...
Bioinorganic chemistry, a discipline that bridges chemistry and biology, has become increasingly popular as new techniques and analytical methods have emerged to study metals in biological systems. One such technique that has become increasingly...
Indole alkaloids -- Synthesis. Ring formation (Chemistry). Radicals (Chemistry).
A novel radical cyclization of 2-bromoindoles was examined, generating a series of hexahydropyrrolo[3,4- b ]indoles in fair yield. This process involved the generation of a variety of indole-3-carboxamides followed by the introduction of bromine at...
Automated trust negotiation is a new approach to access control and authentication for the open systems such as the Internet, where sensitive interactions sometimes occur among entities with no prior knowledge of each other. Trust negotiation...
Prostate cancer (PCa) recurrences are often predicted by assessing the status of surgical margins (SM) – positive surgical margins (PSM) increase the chances of biochemical recurrence by 2-4 times which may lead to PCa recurrence. At present,...
