Non-Invasive Glucose Monitoring: A Novel Approach
No full textBackground: The main concern in noninvasive (NI) glucose measurement is achieving high accuracy readings, although no blood (or other fluid) is involved in the process. Using methods based on different physical properties of a measured object can ensure the independence of each of the readings and therefore improve the validity of the end result. By using a combination of (three) independent technologies—ultrasonic, electromagnetic, and thermal—GlucoTrack™ presents a unique approach for a real-time, truly NI blood glucose spot measurement. Methods: Clinical trials were performed in two stages. Stage 1 was an initial method validation and performance verification of the device. In this stage, 50 type 1 and 2 diabetic patients, as well as healthy subjects, were evaluated with GlucoTrack against Ascensia Elite® (Bayer). In the second stage, 85 additional diabetic subjects were evaluated in half and full daytime sessions using a GlucoTrack comparison with HemoCue® (Glucose 201+). Results: A total of 135 subjects were tested during the trial period, producing 793 data pairs. Using Clarke error grid analysis, 92% of the readings fell in the clinically acceptable zones A and B, with 50% in the A zone. Mean and median relative absolute differences were 29.9 and 19.9%, respectively. Conclusions: Integrating several modalities for NI assessment of glucose level enables more accurate readings, while a possible aberration in one modality is bypassed by the others. The present generation of GlucoTrack gives promising results; however, further improvement of the accuracy of the device is needed.The published version of this article is available at http://www.journalofdst.org/amember/plugins/protect/new_rewrite/login.php?v=-any&url=/March2009/Articles/VOL-3-2-SYM4-HARMAN-BOEHM.pdf%3
Increasing Distributed Generation Penetration using Soft Normally-Open Points
No full textThis paper considers the effects of various voltage control solutions on facilitating an increase in allowable levels of distributed generation installation before voltage violations occur. In particular, the voltage control solution that is focused on is the implementation of `soft' normally-open points (SNOPs), a term which refers to power electronic devices installed in place of a normally-open point in a medium-voltage distribution network which allows for control of real and reactive power flows between each end point of its installation sites. While other benefits of SNOP installation are discussed, the intent of this paper is to determine whether SNOPs are a viable alternative to other voltage control strategies for this particular application. As such, the SNOPs ability to affect the voltage profile along feeders within a distribution system is focused on with other voltage control options used for comparative purposes. Results from studies on multiple network models with varying topologies are presented and a case study which considers economic benefits of increasing feasible DG penetration is also given

Functional dyspepsia
No full textFunctional dyspepsia is one of the most prevalent functional gastrointestinal disorders. Functional dyspepsia comprises three subtypes with presumed different pathophysiology and aetiology: postprandial distress syndrome (PDS), epigastric pain syndrome (EPS) and a subtype with overlapping PDS and EPS features. Functional dyspepsia symptoms can be caused by disturbed gastric motility (for example, inadequate fundic accommodation or delayed gastric emptying), gastric sensation (for example, sensations associated with hypersensitivity to gas and bloating) or gastric and duodenal inflammation. A genetic predisposition is probable but less evident than in other functional gastrointestinal disorders, such as irritable bowel syndrome (IBS). Psychiatric comorbidity and psychopathological state and trait characteristics could also play a part, although they are not specific to functional dyspepsia and are less pronounced than in IBS. Possible differential diagnoses include Helicobacter pylori infection and peptic ulceration. Pharmacological therapy is mostly based on the subtype of functional dyspepsia, such as prokinetic and fundus-relaxing drugs for PDS and acid-suppressive drugs for EPS, whereas centrally active neuromodulators and herbal drugs play a minor part. Psychotherapy is effective only in a small subset of patients, whereas quality of life can be severely affected in nearly all patients. Future therapies might include novel compounds that attempt to treat the underlying gastric and duodenal inflammation.Paul Enck, Fernando Azpiroz, Guy Boeckxstaens, Sigrid Elsenbruch, Christine Feinle-Bisset, Gerald Holtmann, Jeffrey M.

Diverse perspectives on human capital management
No full textThesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management, 2006.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (leaves 97-100).The human resources (HR) function has evolved significantly over the past several decades. It has grown in maturity and influence while simultaneously enduring great criticism from employees and managers. Meanwhile, environmental pressures have forced business leaders and academics to call for the elevation of HR to a level of strategic primacy. This thesis examines the relationship between organizational human capital and the professional HR function, looking at the history and current state of HR, perceptions of HR's efficacy, trends in innovative organizational design and leadership, and the future of human capital management. I explore these issues in the academic and popular literature, survey managers and experts in the field, and present an intra-industry study across several biotechnology firms.by Jeffrey M.

Understanding motivations of sector switchers: towards a holistic approach to public service motivation theory
No full textWhile public service motivation theory (PSM) has addressed numerous topics in the 30-plus years it has been a significant part of the public administration literature, several gaps in the literature are apparent. First, PSM has only recently begun to address the relationship between government partiality, which is at the center of PSM, with other prosocial modes of partiality, such as an interest in nonprofit work. Second, the issue of “sector switchers”—individuals who move from one employment sector to another over the course of their careers—has been significantly under-researched both as a general matter and with specific reference to motivation. Third, PSM research has been largely quantitative in character and may benefit from a rebalancing with qualitative methods. This dissertation, an exploratory study, is a qualitative study of sectorswitchers. It uses phenomenologically oriented interviews with 50 such individuals, selected in a purposeful sample, to add depth to an understanding ofmotivation to work in government as well as other prosocial realms. In so doing, the dissertation addresses a gap identified by one leading PSM researcher searching for more holistic approaches to public service motivation. Themes emerged from the analysis and coding of interview data. Variousmotivations were identified for sectoral switches, including those based in compensation, a need for variety, a desire to serve, the enhancement of one’sprofessional skills, and the desire to advance one’s career. Further, while the study was exploratory and the sample was purposeful and not random, varioustrends seemed apparent, including the fact that sector switchers tend to undergo numerous switches and employment changes over the course of their careersand that, while they often move to the nonprofit sector later in their careers, they tend not to move to, or return to, government work. Tentative conclusions include the identification of tensions between the abstract idea of service, often enunciated in a positive way by respondents, and neutral or negative views about government service, self-sacrifice, and working ina helping profession. A tension was also discerned between government work, which participants viewed more negatively, and nonprofit work, which participantstended to view more positively.Ph.D.Includes bibliographical referencesIncludes vitaby Jeffrey C.

ISOTOPIC RELATIONS FOR HYDROGEN HALIDES.
No full textThe present address of David U. Webb is the Dow Chemical Company, Midland, Michigan 48640. The present address of Jeffrey M. Luce is Block Engineering. Inc, Cambridge, Mass. 02139.Author Institution: Department of Physics, The Ohio State UniversitySpecially designed computer programs have been written which allow accurate determination of the Dunham potential constants of diatomic molecules. The computation process will be discussed in detail and graphical representations of the potential functions obtained using computer techniques will also be discussed. It is possible to predict the values of the equilibrium constants for all isotopic substituted species of the molecule after the potential constants are known. Band origins and rotational constants can be calculated from the equilibrium constants and compared with experimental results. Recent high resolution infrared measurements of HF and three isotopic substituted species of HCl at The Ohio State University and other studies of the hydrogen halides are compared with predicted results and excellent agreement is obtained in many cases
A distribution study of deep-sea macrobenthos collected from the western Gulf of Mexico
No full textVita.One of Texas A&M University's more detailed oceanographic cruises was that of R/V ALAMINOS 69A11, basically biological in scope but also including hydrographic, sediment coring, and bottom photography stations. Dredge sampling of the deep-sea macrobenthos was accomplished by means of the benthic skimmer in three western Gulf regions (Galveston, Tampico, and Vera Cruz). This distribution study of the benthic macrofauna revealed five faunal zones that were differentiated on a bathymetric basis. These have been designated as Outer Continental Shelf, Upper Continental Slope, Lower Continental Slope, Continental Rise, and Abyssal Plain. Faunal breaks revealed by the similarity dendrogram, constructed from individual station data, support the proposed faunal zones. Recurrent patterns of species occurrence were used to formulate benthic assemblage, showing expected species and their relative abundance, for specific depths within the faunal zones. Data concerning species occurrence within the three geographic regions of the western Gulf under consideration were not sufficient to warrant extension of existing biotic provinces into the deep sea. Analysis of sea-floor photographs revealed at least 87 living organisms, various plant fragments, sediment composition and texture, and other ichnological phenomena. Several selected photographs have been included. A phylogenetic list of all benthic species, including author and date, collected as living specimens at one or more of the dredge stations has been compiled. Slight modification and combination of the suprageneric taxonomy used by earlier authors was utilized
