(B&W) ECG Cardiac Rhythms - Practical Interpretation with QRS Vectors By Dr. Jorge Uzquiano
Paperback: $6.48
Prints in 3-5 business days
The author suggests the addition of 3 extra electrodes to the Modern 12 Lead ECG Machine – resulting in the 15 Lead ECG Machine – to visualize cardiac vectors with a tridimensional view... More > (3D ECG View). With research gathered on cardiac vectors with this new technology, the author presents this book to provide a new generation of medical professionals with a reference on Surface ECGs. This book builds on the author’s conviction that cardiac vector analysis is the only path to a simple and proper ECG and cardiac rhythms and interpretation. Narrow vectors are of Purkinje’s Supraventricular origin; Wide onset Complexes are Ventricular Beats. Non ST, Subendocardial Infarcts are Posterior Infactrs. Incomplete Bundle Branch Blocks are actually delayed normal ventricular vectors. Vector Axis Deviations are indicative of Hemiblocks, Idio-Fascicular Rhythms.< Less
Vector Borne Disease: Environmental Risk Factors and Sustainable Control Programs By June Weintraub
eBook (PDF): $0.00
This literature review seeks to identify the "root causes" of several diseases that are transmitted among humans by insects and other animals, known as vectors. With an understanding of the... More > causes underlying the occurrence of vector-borne diseases, effective approaches to their control and management are identified. The approaches suggested by this investigation attack many of the factors common to these diseases; but in order to achieve sustained positive results, a vector-borne disease management program must acknowledge and overcome a number of obstacles.< Less
Axially Rotating Vector Frames Completely Differentiated In Four Dimensional Space-time By Gary DeWoolfson
eBook (PDF): $3.77
Functions that multiply the vectors we obtain by differentiating space-time points partially with respect to scalar parameters that are in a 1-to-1 and onto relationship with the points may change... More > the size we associate with a given direction, but not the direction, so that by changing the coefficient functions we change the parallelepiped shapes associated with each origination of four different directions at each space-time point. Thusly do derivatives of products made between basis vectors and their coefficient functions become of geometric interest. Moreover, a 1-to-1 and onto relationship between space-time points and their four corresponding parametric scalar values connotes that the latter can be differentiated by means of gradients taken with respect to the coordinates of the former, so that meaningful shape changing in space-time nurtures expectations for complementary effects being useful to the regulation of the dual space that the gradients generate. These issues are explored herein.< Less

More > accumulation of human knowledge and a poetic gesture towards the inhuman scale of big data. Michael Mandberg wrote software that parses the entirety of the English-language Wikipedia database and programmatically lays out nearly 7500 volumes, complete with covers, and then uploads them to for print-on-demand. Print Wikipedia draws attention to the sheer size of the encyclopedia's content and the impossibility of rendering Wikipedia as a material object in fixed form: Once a volume is printed it is already out of date. It is also a work of found poetry built on what is likely the largest appropriation ever made. As we become increasingly more dependent on information and source material on the Internet today, Mandiberg explores the accessibility of its vastness.< Less

Spatio-temporal reconstruction of satellite-based temperature maps and their application to the prediction of tick and mosquito disease vector distribution in Northern Italy By Markus Neteler

Continuous monitoring of extreme environments, such as the European Alps, is hampered by the sparse and/or irregular distribution of meteorological stations, the difficulties in performing ground... More > surveys and the complexity of interpolating existing station data. Remotely sensed Land Surface Temperature (LST) is therefore of major interest for a variety of environmental and ecological applications. But while MODIS LST data from the Terra and Aqua satellites are aimed at closing the gap between data demand and availability, clouds and other atmospheric disturbances often obscure parts or even the entirety of these satellite images. A novel algorithm is presented which is able to reconstruct incomplete MODIS LST maps. Nine years of daily LST data (2000–2008) have been processed, allowing the original LST map resolution of 1,000 m to be improved to 200 m, which means the resulting LST maps can be applied at a regional level. Aggregated data are applied to predict presence of ticks and tiger mosquitoes.< Less
