Timing and Rates of Two Products Using Hydrogen Peroxide (H2O2) to Control Algae in Ebb and Flow Hydroponic Systems

Algae is not desirable in hydroponics and creates problems such as reduced yield and decreased dissolved oxygen, and affects the physiology of plants and, thus, needs to be controlled. An experiment was conducted in Ebb and Flow hydroponic systems to investigate the application timing and rates of two hydrogen peroxide products (Zerotol and PERpose Plus). Treatments included 35 mL weekly, 35 mL biweekly, 70 mL weekly, 70 mL biweekly, and a control with no application of hydrogen peroxide using a 40-gallon reservoir of water. Pepper ‘Early Jalapeno’ and ‘Lunchbox Red’ and tomato ‘Geronimo’ and ‘Little Sicily’ were used. The study was conducted in a split-plot design with two replications over time. Plant growth parameters, including plant height, flower number, net CO2 assimilation, fresh weight, and dry weight were recorded. Algae data, including dry weight, algae cell counts, and chl a were also measured. Results indicated that with increasing rate and timing of either product decreased algae counts, dry weight, and chl a values. However, weekly and biweekly application of 70 mL of both products were not different for algae quantification. In pepper, plant height, shoot fresh and dry weight, and root fresh and dry weight were found to be significantly greater with Zerotol 35 mL biweekly, Zerotol 70 mL weekly, PERpose Plus 35 mL biweekly, and PERpose Plus 70 mL weekly compared with the control. ‘Lunchbox Red’ was significantly greater than ‘Early Jalapeno’ in all growth parameters, except soil plant analysis development (SPAD). ‘Lunchbox Red’ had the greatest flower number, with weekly application of 70 mL PERpose Plus. In tomato, greatest flower number and SPAD were observed in ‘Geronimo’ with a weekly application of 70 mL PERpose Plus and 70 mL Zerotol, respectively. Greater shoot and root fresh and dry weight for both tomato cultivars were recorded with 35 mL biweekly or 70 mL weekly application with either product. The results from both plants as well as algae analysis suggest that weekly application of 70 mL of either Zerotol or PERpose Plus produced the best results in terms of controlling algae and improving the growth of pepper and tomato plants.

Climate Sadness: The Fragile Beauty of Tonlé Sap

Tonlé Sap is the large fresh water lake-river near the geographic center of Cambodia. Visiting Tonlé Sap, following an academic conference in Phnom Penh, demanded a response at a personal and more visceral human level. Writing this poem attempted to express disquiet beyond academic examination of the biophysical dimensions of Tonlé Sap. The poem is sad for Tonlé Sap, for Cambodia, and implicitly for all of us on this planet. For thousands of years people have lived around Tonlé Sap, adapting to weather, the flow of water from mountain to sea, and the changing ebb and flow of civilizations. Anthropogenic sea level rise challenges all of this human history, unnecessarily.

How adopters’ and foster carers’ perceptions of ‘family’ affect communicative openness in post-adoption contact interactions

This article explores the constructions of communicative openness following adoption. Data from three waves of interviews with six adoptive mothers and four foster carers were collected, transcribed verbatim and analysed in keeping with a social constructivist grounded theory methodology. The results show that the way ‘family’ is constructed can both facilitate and impede communicative openness. Those who hold a fluid, child-centred concept of family, are willing to construct it as different and can accept the ebb and flow of family membership intuitively and view such openness as a natural part of caring for children. Those with a more traditional, nuclear construction of family may associate adoption with fear, a sense of biological related competition and the need to control the controllable, all of which act as barriers to communicative openness. The study demonstrates that communicative openness is person and context sensitive and emphasises the need to think creatively and flexibly about the very nature of family.

The Age of Questions: Or, a First Attempt at an Aggregate History of the Eastern, Social, Woman, American, Jewish, Polish, Bullion, Tuberculosis, and Many Other Questions Over the Nineteenth Century, and Beyond, by Holly Case, 2018.

Holly Case’s most adventurous work as of yet seeks to juxtapose patterns common to nineteenth century publicists’ questions in order to reveal the contradictions of the age. Case devotes each chapter to a particular theme or ideological quality of the querists, which are in dispute with one another, and yet feature common idioms of progress and geopolitical reconfiguration. Internal to each chapter are the oxymoronic imbrications between conceptual polarities such as nationalism and the international public sphere, war through peace, gravitas with farce, and more. Case explains the prevalence of high-stakes public policy, prospects of war and the convulsive realignment of empires and nations through the persistent bundling of many of these questions. She addresses the ebb and flow of popularity of many era-spanning questions, which strengthens her attempt to provide a genealogy for the crises and ‘questions’ of our current era, and her accounting for how queristic contradictions were perceived to be transcended. It is reasonable to suggest that Case has provided a foundational step for an emergent niche of epistemological inquiry in the historical discipline, not unlike Benedict Anderson’s contribution to the study of nationalism through his magnum opus Imagined Communities.

Rewriting Mansfield: Writing, Editing and Translation

<p>This thesis explores the notion, the process and the ethical implications of rewriting, drawing on insights from literary and translation theories, psychoanalysis and trauma studies. It analyses three major forms of rewriting: the author’s, the editor’s and the translator’s. While writing, editing and translation have their own specific norms of production, methodologies, possibilities and limits, all these textual practices are implicitly concerned with the meaning-making process of rewriting. Chapter One presents the central case study of the project: John Middleton Murry’s editing of Katherine Mansfield’s notebooks, which resulted in the publication of Journal of Katherine Mansfield (1927). The chapter reviews relevant Mansfield scholarship and discusses textual, methodological and theoretical issues concerning the problem of rewriting. Chapter Two follows the ebb and flow of Mansfield’s own rewriting process by discussing the ways in which she ‘translated’ her notebook entries into her fiction. Chapter Three offers a re-reading of the Journal of Katherine Mansfield and sheds new light on Murry’s controversial editorial manipulation. Chapter Four examines the first Italian translation of the Journal – Diario di Katherine Mansfield, authored by Mara Fabietti in 1933 – and my own re-translation of ‘Life of Ma Parker’ – a 1921 Mansfield story that epitomizes the main themes and issues addressed in this study. This thesis demonstrates how deeply intertwined writing, editing and translating are, and presents an understanding of rewriting as a complex and fascinating process that simultaneously resists meaning and yearns for it.</p>

Akibat Hukum Pembubaran Koperasi Terhadap Hak dan Kewajiban Anggota

In running a cooperative business, of course, the ups and downs of the economic situation greatly affect the profit and loss of a business, in the ups and downs the cooperative can develop and develop its business so that it gets bigger, but in the ebb and flow conditions the cooperative can also experience losses that will have an impact on business continuity to cause the cooperative to go bankrupt or dissolution of the cooperative. The dissolution of a cooperative certainly has legal consequences for both the management and the members. The purpose of this study was to determine the legal consequences of the dissolution of the cooperative on the rights and obligations of members. This study uses normative research with a statutory approach, a conceptual approach, and a case approach. Sources of legal materials used in the form of secondary, primary and tertiary legal sources and then analyzed descriptively. The results of the study reveal that the legal consequences that occur after the dissolution of the cooperative, namely the cooperative legal entity must be settled, operational transactions are terminated, employees can be terminated, members can no longer resign, the powers of the cooperative apparatus are frozen and are also replaced by liquidators, and management and supervisors can be held accountable both civilly and criminally if it is proven that due to their mistakes and negligence the cooperative has gone bankrupt. In addition, the legal entity of the cooperative will also be deleted

‘Open Purpose’: Embracing Organizations as Expressive Systems

The concept of purpose gained prominence in organization theory in recent years but there are discrepant views of its meaning, which we review as evolving and different perspectives: economic theories of the firm; stakeholder approaches; integrative social contracts; and social mission. We elaborate these perspectives in terms of the ebb and flow of ideas and eras. Against these instrumental views, we revisit the work of Robert Cooper, namely the ever-open purpose of expressive organizations, and contrast this with fixist views of purpose in instrumental organizations. We engage with the logic of open purpose and sketch a way of rethinking purpose as a general orientation that constantly evolves and changes over time in interaction with its ecosystem.
