Application of abandoned wells integrated with renewables
No full textThe large thermal potentials with geothermal gradient of abandoned wells provide the possibility and opportunity for carbon-neutrality transition of district heating systems, whereas energy harvesting from abandoned geothermal wells is full of challenges, due to the considerable initial investment in economic cost, system performance degradation, and so on. In this chapter, a systematic and comprehensive review on the application techniques of abandoned wells is presented, in terms of advanced thermal/power conversions, renewable integrations for district heating, and strategies for performance enhancement. Discussions on real applications have been conducted and future prospects presented, from perspectives of lifetime system performance, techno-economic feasibility analysis, and potential assessment of abandoned wells for carbon-neutrality transition. The results of this chapter can provide preliminary knowledge and cutting-edge technologies on renewable integrations with abandoned wells, so as to demonstrate techno-economic-environmental potentials of abandoned wells and contributions toward carbon-neutrality transition.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Design & Construction Managemen
Professor Wells: the Educational Purposes of H.G. Wells’ Works
No full textreservedThis dissertation analyses the educational purposes of H.G. Wells’ works. Wells is
known as one of the fathers of science fiction, and as one of the most influential writers of the late
nineteenth century. However, I will not focus on H.G. Wells as an author. I will focus on H.G. Wells
as a teacher. Education played a key role in the life of this remarkable author. He not only spent some
of his early years working as a teacher, but he also wrote a textbook meant for biology students.
Furthermore, in the later stages of his life Wells actively advocated for the need to reform the British
school system, introducing scientific subjects in the school curricula. He also dedicated himself to
writing popularizing articles about scientific topic. The strong connection between Herbert George
Wells and education is, to me, quite evident. Every chapter of this work will focus on a different work
written by Wells. I chose to follow on some of his most famous works: The Island of Doctor Moreau
(1896), The Time Machine (1895), and The World of the Worlds (1898). Here, I will analyse the
content of each work, trying to point out the educational narrative proposed by Wells. I am not
proposing anything new as far as the interpretation of these works is concerned. In order to carry out
my researches for the dissertation, I attentively read many essays and articles that proposed an
interpretation of Wells’ texts. Among the authors I refer to, there are authoritative Wells’ scholars
such as Patrick Parrinder. The purpose of the work is not providing a new interpretation of the themes
and motifs behind H.G. Wells’ works, but demonstrating that these books had been written in order
to teach something to their reading public.
The last chapter focuses on Wells’ utopian novel A Modern Utopia (1905). It is different from
the others because I will not limit myself to describing the educational purposes of the book. A
Modern Utopia is a programmatic text, and this gave me the possibility to have a closer look at Wells’
beliefs and plans for society. As I propose in the fifth chapter, some of his views would be considered
completely unacceptable by modern-day readers. I focus on two specific topics. First, I will take into
exam the treatment received by criminals, feeble-minded, drunkards, and other sorts of people
considered “undesirable” by the Victorians. And then I focus on the role of the woman in the utopian
state imagined by Wells. As I will discuss, Wells’ ideas were far from progressive as far as these
topics were concerned. Or, at least, they could not be considered progressive nowadays. The final
chapter is not a way to stigmatise Wells. Rather, it is a way to contextualise both the man and his
works. As I propose, contextualising Wells is the only way to truly appreciate the innovative
contributions of his works.This dissertation analyses the educational purposes of H.G. Wells’ works. Wells is

Spin relaxation and carrier recombination in GaInNAs multiple quantum wells
No full textElectron spin relaxation and carrier recombination were investigated in gallium indium nitride arsenide (GaInNAs) multiple quantum wells, using picosecond optical pulses. Pump-probe experiments were carried out at room temperature, using pulses produced by a Ti:sapphire pumped optical parametric oscillator.
The peak wavelengths of the excitonic resonances for the quantum well samples were
identified using linear absorption measurements, and were found to be in the range 1.25µm-1.29µm.
Carrier recombination times were measured for three samples of varying nitrogen content, and were observed to decrease from 548 to 180ps as nitrogen molar fractions were
increased in the range 0.45-1.24%. Carrier recombination times were also measured
for samples which had undergone a post-growth annealing process, and were found to be
signicantly shorter compared to times measured for as-grown samples.
Electron spin relaxation time was investigated for samples with quantum well widths in the range 5.8-8nm, and was found to increase with increasing well width, (i.e. decreasing quantum confinement energy), a trend predicted by both D'Yakonov-Kachorovskii and
Elliott-Yafet models of spin relaxation in quantum wells. In a further study, longer spin relaxation times were exhibited by samples containing higher molar fractions of nitrogen, but having nominally constant quantum well width. Spin relaxation times increased from 47ps to 115ps for samples containing nitrogen concentrations in the range 0.45-1.24%. Decreases in spin relaxation time were observed in the case of those samples which had been annealed post-growth, compared to as-grown samples.
Finally, all-optical polarisation switching based on spin relaxation of optically generated carriers in GaInNAs multiple quantum wells was demonstrated

Defender: the life of Daniel H. Wells
No full textIncludes bibliographical references and index.Defender is the first and only scholarly biography of Daniel H. Wells, one of the important yet historically neglected leaders among the nineteenth-century Mormons—leaders like Heber C. Kimball, George Q. Cannon, and Jedediah M. Grant. An adult convert to the Mormon faith during the Mormons’ Nauvoo period, Wells developed relationships with men at the highest levels of the church hierarchy, emigrated to Utah with the Mormon pioneers, and served in a series of influential posts in both church and state. Wells was known especially as a military leader in both Nauvoo and Utah—he led the territorial militia in four Indian conflicts and a confrontation with the US Army (the Utah War). But he was also the territorial attorney general and obtained title to all the land in Salt Lake City from the federal government during his tenure as the mayor of Salt Lake City. He was Second Counselor to Brigham Young in the LDS Church's First Presidency and twice served as president of the Mormon European mission. Among these and other accomplishments, he ran businesses in lumbering, coal mining, manufacturing, and gas production; developed roads, ferries, railroads, and public buildings; and presided over a family of seven wives and thirty-seven children. Wells witnessed and influenced a wide range of consequential events that shaped the culture, politics, and society of Utah in the latter half of the nineteenth century. Using research from relevant collections, sources in public records, references to Wells in the Joseph Smith papers, other contemporaneous journals and letters, and the writings of Brigham Young, Quentin Thomas Wells has created a serious and significant contribution to Mormon history scholarship.--Provided by publisher.1634-1814, a Puritan family's progress: the Wells' migration from England to America -- 1814-1838, Daniel H.

Ida B. Wells-Barnett letter to Lucile Atcherson, October 1, 1914
No full textIn October 1914, Ida B. Wells-Barnett, a journalist and leader in the early Civil Rights movement, wrote this letter to Lucile Atcherson, a leader in the Ohio women's suffrage movement and executive secretary for the Franklin County Woman Suffrage Associatino. Wells-Barnett, writing from Chicago, asks in the letter how she can help in the fight for suffrage following a request from Mrs. Jamison for Wells-Barnett's help in garnering enthusiasm for the movement from African American women. Wells-Barnett's suffrage club in Chicago could not spare money to fund her travel, so she requests money from Atcherson for the train. Wells-Barnett asks Atcherson to respond if the plan for the trip is satisfactory.
The Franklin County Woman Suffrage Association was formed in 1912, after the Ohio Constitutional Convention elected to bring to a vote the question of removing the words "white male" from the state constitution with regard to voting rights. Headquartered in the Chamber of Commerce building in Columbus, Ohio, the organization put out regular publications, organized public speeches and meetings, distributed literature and held parades in support of the suffrage movement. Women's suffrage in Ohio was defeated in a special election in 1912 and again in 1914 and 1916 before a resolution narrowly passed in 1917 allowing municipal voting by women in Columbus. In 1920, the 19th Amendment passed, extending the vote to women and prohibiting state and federal government from denying suffrage on the basis of sex
