Pollen Analysis of a Peat Deposit in Livingston County, Illinois

This study essays to compare, and in some degree to supplement, pollen analyses thus far published for Illinois. Even though results of studies of fossil pollens seem very similar, each pollen profile is individual and varies in many details from all other profiles. For this reason, each new analysis is more than a repetition of what has already been studied and reported; it is a possible verification of these previous studies and a valuable supplement to the growing science of pollen analysis. It is hoped that the preliminary study of fossil diatom valves found in this deposit can be correlated with the fossil pollen record, and possibly reveal valuable additional data in the quest for information on the history of the pond and of climates of its vicinity

End of Life in the ED – Brain Death and Organ Transplantation

Brain death is defined as the irreversible loss of all brain and brainstem functions. While the criteria for diagnosing brain death have been established and refined since 1995, physicians remain uncomfortable with making the diagnosis leading to delays in pronouncing the patient as brain dead. While seemingly benign, a delay in pronouncing a patient as brain dead can place a financial burden on the family and cause additional and unnecessary emotional distress. Furthermore, delayed pronunciation of death causes improper delegation of the medical care team\u27s resources and loss of the patient\u27s potential to serve as an organ donor. The purpose of this research is to outline and review the currently accepted clinical criteria to determine brain death at the bedside by examining the relevant neuroanatomical pathways of brain stem reflexes and spinal tracts involved in each diagnostic test. We hope that by illuminating the underlying pathophysiology of loss of brainstem reflexes this paper can serve as a tool for providers to better understand brain death and become comfortable with making the diagnosis in a timely manner

Customer Relationship Management: A Theoretical Overview and the High Cost of Failure (a Case Study)

Despite the significant benefits offered by the customer relationship management (CRM) strategy together with advanced technology, there is still a high rate of companies who fail to see results promised by CRM in order to achieve a competitive advantage. A review of the empirical literature together with the case study of the CRM implementation within a midsize financial firm will result in deeper understanding of current CRM practices that could contribute to better planning, selection, and implementation of customer relationship management programs

CRM in Russia and U.S. -- Case Study from American Financial Service Industry

This paper discusses Customer Relationship Management in two sharply contrasting business cultures: the United States and Russia. Included in the present work is a case study of a midsized American financial services firm that illustrates a common path to the decision to have a CRM system: the planning, selection, and the implementation of the CRM program, including a discussion of the likelihood of success. The clients in this case are Financial Advisors, who in turn sell the investment products to the end user individual investors. CRM in Russia is yet in its infancy as the economy emerges from 200 years as a pure commodity economy with little customer service much less customer relationship management as part of management philosophy. The study concludes with implications and suggested research

Development and initial evaluation of a dynamic species-resolved model for gas phase chemistry and size-resolved gas/particle partitioning associated with secondary organic aerosol formation

A module for predicting the dynamic evolution of the gas phase species and the aerosol size and composition distribution during formation of secondary organic aerosol (SOA) is presented. The module is based on the inorganic gas-aerosol equilibrium model Simulating the Composition of Atmospheric Particles at Equilibrium 2 (SCAPE2) and updated versions of the lumped Caltech Atmospheric Chemistry Mechanism (CACM) and the Model to Predict the Multiphase Partitioning of Organics (MPMPO). The aerosol phase generally consists of an organic phase and an aqueous phase containing dissolved inorganic and organic components. Simulations are presented in which a single salt (either dry or aqueous), a volatile organic compound, and oxides of nitrogen undergo photo-oxidation to form SOA. Predicted SOA mass yields for classes of aromatic and biogenic hydrocarbons exhibit the proper qualitative behavior when compared to laboratory chamber data. Inasmuch as it is currently not possible to represent explicitly aerosol phase chemistry involving condensed products of gas phase oxidation, the present model can be viewed as the most detailed SOA formation model available yet will undergo continued improvement in the future

Secondary organic aerosol 1. Atmospheric chemical mechanism for production of molecular constituents

This series of three papers addresses the representation of secondary organic aerosol (SOA) in atmospheric models. SOA forms when gas-phase organic species undergo oxidation, leading to products of sufficiently low vapor pressure that can partition between the gas and aerosol phases. The present paper, part 1, is devoted to the development of a gas-phase atmospheric chemical mechanism designed to represent ozone chemistry as well as formation of individual organic oxidation products that are capable of forming SOA. The ozone chemistry in the mechanism draws upon the recent work of Stockwell et al. [1997] and Jenkin et al. [1997] and SAPRC-97 and SAPRC-99 (available from W.P.L. Carter at http://helium.ucr.edu/~carter/). The mechanism is evaluated in the three-dimensional California Institute of Technology (CIT) model [Meng et al., 1998] by simulating gas-phase concentrations in the South Coast Air Basin (SoCAB) of California over the period 27–29 August 1987. Total predicted concentrations of gas-phase SOA compounds are compared with levels of SOA that have been inferred on the basis of ambient organic aerosol measurements during this period. These predicted concentrations indicate that the total gas-phase potential of SOA-forming compounds can account for observed aerosol concentrations. Part 2 develops a thermodynamic gas–aerosol partitioning module, and part 3 presents a full three-dimensional simulation of gas and aerosol levels in the SoCAB during a 1993 episode

The limitations on applying classical thin plate theory to thin annular plates clamped on the inner boundary

The experimentally measured resonance frequencies of a thin annular plate with a small ratio of inner to outer radii and clamped on the inner boundary are compared to the predictions of classical thin-plate (CTP) theory and a finite-element (FE) model. The results indicate that, contrary to the conclusions presented in a number of publications, CTP theory does not accurately predict the frequencies of a relatively small number of resonant modes at lower frequencies. It is shown that these inaccuracies are attributable to shear deformations, which are thought to be negligible in thin plates and are neglected in CTP theory. Of particular interest is the failure of CTP theory to accurately predict the resonance frequency of the lowest vibrational mode, which was shifted approximately 30% by shear motion at the inner boundary
