Measurement, Characterization, and Source Apportionment of the Major Chemical Components of Fine Particulate Material, Including Semi-Volatile Species

Grover, Brett D. 16 February 2006 (has links) (PDF)
The promulgation of revised standards for atmospheric fine particles (PM2.5) by the US EPA has sparked renewed interest in the ability to accurately measure and characterize suspended atmospheric particulate matter. Semi-volatile material (SVM), consisting of ammonium nitrate and semi-volatile organic material (SVOM), is not accurately measured by EPA accepted methods such as the Federal reference method (FRM) or Tapered Element Oscillating Microbalance (TEOM). However, SVM is often a major fraction of urban aerosols. Recent advances in atmospheric sampling instrumentation allowed for the semi-continuous characterization of urban PM2.5, including SVM. The Filter Dynamic Measurement System (FDMS) was shown to measure total PM2.5 mass including semi-volatile species. Validation of the FDMS was performed by comparison with the particle concentrator-Brigham Young University organic sampling system (PC-BOSS) and the real-time total ambient mass sampler (RAMS). Semi-continuous ambient particulate concentrations of sulfate, nitrate and ammonium ion were measured by a newly developed Dionex instrument which was field tested and validated for the first time in Fresno, CA. Either a modified Sunset Laboratory carbon monitor, collocated with a conventional Sunset carbon monitor employing a common inlet, or the newly developed dual-oven Sunset monitor allowed for the semi-continuous determination of both nonvolatile and semi-volatile organic material. This was the first attempt to characterize both nonvolatile and semi-volatile fractions of an urban aerosol in a semi-continuous manner using all semi-continuous instruments. A suite of instruments for semi-continuous PM2.5 monitoring was recommended including, an R&P FDMS for the measurement of PM2.5 mass, a dual-oven Sunset monitor for the measurement of nonvolatile and semi-volatile carbonaceous species, and a Dionex GP-IC for the measurement of inorganic species. A TEOM monitor is also recommended to measure nonvolatile PM2.5 mass. Using these instruments, semi-continuous mass closure was obtained for the first time during a study conducted in Riverside, CA. The advantage of using semi-continuous sampler data in the application of source apportionment was elucidated. Local aerosols are often impacted by short-term pollution episodes that cannot be temporally resolved using integrated samplers. One-h averaged data applied to source apportionment models was shown to increase the power of the model to predict sources, both primary and secondary, that exhibit diurnal short-term episodes.

Murphy, Michael W., Barkenhagen, Michael E. 03 1900 (has links)
Approved for public release; distribution in unlimited. / This thesis represents a cross Systems Command (NAVSEA/NAVAIR) developed product. The product - the Sunset Supply Base (SSB) system - provides a complete system for addressing the risks and supportability issues involved with Commercial Off the Shelf (COTS) products in Navy combat and support systems. The SSB system was implemented on three Navy combat weapon systems at various phases of the product development life cycle. The main body provides to the Program Management Offices (PMO) and other decision makers, a high level summary of performance expectations. Appendix A - The Sunset Supply Base Architecture - identifies at a high level of abstraction a collaborative architecture providing a roadmap for design and development of the SSB system. Appendix B - The Systems Engineering Development and Implementation (SEDI) plan - is a prescriptive or "How to" manual describing activities that have been used to successfully implement the SSB system. Appendix C - Business Case Analysis (BCA) - presents the data collected as a result of SEDI plan implementation then addresses the business/programmatic attributes showing the viability and value proposition possible through the SSB system. Appendix D - The Marketing Plan for the SSB system - defines methods and practices necessary to establish the SSB system as the alternative of choice. / Chemical Engineer, United States Navy / Systems Engineer, United States Navy

Stanovení spotřeby elektrické energie pro veřejné osvětlení / Analysis of Electric Power Consumption of Public Lighting

Varmuža, Jan January 2011 (has links)
The thesis deals with analysis of the public lighting system from the point of view of light sources and luminaries. It focuses on the specifics of the lighting systems such as lighting for pedestrian crossings or decorative lighting. It analyzes the energy consumption depending on daylight and how it manifests a shift sunrise and sunset on the consumption of electricity. The work clarifies how the model can be simplified sunrise, sunset for the entire Czech Republic. Based on the distribution of municipalities with population over 10,000 and modeling of sunrise and sunset calculation is carried out power consumption of lighting systems and compared to the total consumption of the Czech Republic. Simplification is an estimate of the consumption of electricity to villages to 10 000 people on the basis of the estimate, the final consumption of electricity for public lighting for the entire Czech Republic.

Les clauses de fin de contrat / End-of-contract clauses

Frasson, Vanessa 24 October 2014 (has links)
Les clauses de fin de contrat illustrent l’importance de la liberté contractuelle. La pratique s’est emparée de cette période de l’« après-Contrat » sous le contrôle de la jurisprudence, dans le relatif désintérêt du législateur.Les fins du contrat sont diverses. La fin peut être retardée par le biais de la prorogation du contrat. La fin peut être prématurée : elle peut être une fin brutale et définitive par le biais de la clause résolutoire, la continuité de ce qui était par l’arrivée du terme extinctif, ou encore la venue de quelque chose de nouveau par le biais d’une clause de caducité. La fin peut n’être qu’un passage vers un autre contrat par le biais de la reconduction. Il en ressort un flou théorique nécessitant une construction juridique. Il peut être proposé de scinder le temps de l’après-Contrat en trois temps. Le premier temps, les parties satisfaites de leur relation vont chercher à la faire perdurer. Les clauses de fin de contrat ont alors pour finalité la préservation de la pérennité du lien contractuel entre les parties. La deuxième période porte sur les modes d’extinction du contrat. La sortie de la relation contractuelle est devenue un enjeu important nécessitant le recours à différents mécanismes juridiques tels que la clause de dédit, la condition résolutoire ou encore la clause résolutoire.La troisième période peut être désignée comme la période de liquidation du passé contractuel comprenant deux séries de clauses : celles liquidant le passé contractuel (notamment la clause de non-Concurrence et la clause de confidentialité) et celle s’intéressant à l’avenir post-Contractuel. La fin du contrat doit être distinguée de la clôture de la relation contractuelle désignant la cessation de toutes les obligations post-Contractuelles et de leurs conséquences. Ainsi loin d’être secondaires, ces clauses de fin de contrat composant la période de l’après-Contrat sont fondamentales pour toute relation d’affaires continue. / End-Of-Contract clauses illustrate the significance of contractual freedom. Practice took hold of this “post-Contractual” period under the control of established precedents, in the relative disinterest of lawmakers.The types of contractual ends are diverse. The end may be delayed by means of prolongation of the contract. The end may come prematurely: it may come suddenly and definitively by means of a termination clause, the continuity of that which was by the arrival of the extinctive term, or the arrival of something new by means of a sunset clause. The end may only be a passage to another contract by means of renewal. This results in a lack of theoretical clarity that requires a legal structure. It may be proposed to divide the post-Contractual period into three parts. In the first part, parties satisfied with their relationship will seek to have it continue. The end-Of-Contract clauses thus serve the purpose of preserving the durability of the contractual bond between the parties. The second part involves the manner of termination the contract. Closing the contractual relationship has become an important matter that requires resorting to different legal mechanisms such as the forfeiture clause, the termination condition or the termination clause.The third part may be referred to as the period of liquidation of the contractual past including two series of clauses: those liquidating the contractual past (notably the clause of non-Competition and the clause of confidentiality) and those concerning the post-Contractual future. The end of the contract must be distinguished from the close of the contractual relationship designating the cessation of all post-Contractual obligations and their consequences. Thus, far from being secondary, these end-Of-Contract clauses affecting the post-Contractual period are fundamental for any ongoing business relationship.

Naujosios viešosios vadybos patirtis Danijoje ir jos diegimo galimybės Lietuvoje / Experience of New Public Management in Denmark and It’s Deployment Opportunities in Lithuania

Lichtinšain, Jelena 25 January 2007 (has links)
This research describes and compares different approaches of the Better Regulation implementation in Danish Ministry of Industry & Trade and Lithuanian Ministry of Economics. These two ministries have been facing many common management problems relatively at the same time period, along with the ever-changing economic challenges and EU requirements. While the Danish ministry is being one of the most effectively restructured and de-burocratized into a project organization in EU, the Lithuanian Ministry of Economics remains at quite a low level of reformation. Even though both of these ministries had common goals, their reform purposes were completely different: the Danish reform was about to increase the Ministry’s capacity in developing new policy initiatives, to increase flexibility in resource allocation, and to make the organization an attractive working place for future graduates from universities; while the purposes of Lithuanian reform are still more about general compatibility with EU requirements.

The evolution of Sunset Magazine's cooking department: The accommodation of men's and women's cooking in the 1930s

Pagano, Jennifer Hoolhorst 01 January 2019 (has links)
The Western regional magazine Sunset has been published under a series of owners and publishers since 1898. In 1928, Sunset was purchased by Lawrence Lane, a Midwestern magazine executive who transformed it from a failing turn-of-the-century, general interest publication about the West, into a successful magazine about living in the West for the Western middle-class. Sunset had always been a magazine for men and women, and one that appealed to both male and female intellectuals at the time Lane purchased it. Lane and his editors attempted to interject more rigid middle-class ideals into a magazine that had espoused ideas that were progressive and less structured. Lane's new strategy to compartmentalize Sunset's content into its four categories—gardening, the home, cooking, and travel—resulted in a magazine that was conventionally gendered. Tension due to this shift played out in the publication's new cooking department. This thesis traces the development of Sunset's cooking department between 1928 and 1938 under the direction of its creator and founding editor Genevieve Callahan through the examination and analysis of Sunset cooking features and oral histories. The original department, structured to model a middle-class domestic ideology, did not accommodate all of Sunset's readers. The Western intellectualism of pre-Lane readers and their tendency to be less bound by conventional gender roles in the kitchen carried over into Sunset's cooking department via reader recipe contributions. These Western cooks included men and women whose foodways deviated from that of the typical middle-class housewife. Callahan experimented throughout the cooking department's first decade by shifting its editorial framework and softening her home economics rigidity to create a department that was inclusive of women and men who cooked both inside and outside the kitchen. The changes made to the department over that decade illustrate how editorial experimentation reconciled a new middle-class-oriented cooking department to accommodate Western cooks less apt to model traditional gender roles.
