This report presents a simple way of estimating friction drop along the lateral line, pressure distribution along the drip line, and variation of emitter discharge along the lateral. Design charts are presented for determining pressure and length of the lateral lines and submains of a drip irrigation system

Special Proceedings in Ohio: What Is the Ohio Supreme Court Doing with the Final Judgment Rule

This note will analyze special proceedings in Ohio insofar as they relate to the appealability of interlocutory orders. Because of the complex and evolving nature of the Ohio Supreme Court\u27s interpretation of special proceedings, this note\u27s analysis must necessarily be largely descriptive of Ohio case law. In addition, this note will highlight differences between Ohio appellate practice and federal practice in order to acquaint the reader with the dramatically different results reached by the two systems. In addition, Part II of this note will examine what is meant by the phrase substantial right, which appears in the second prong of Ohio\u27s final order rule. Part III will analyze the historical development of the special proceeding, from its initial statutory creation to the landmark case of Amato v. General Motors Corp. Part IV will examine a selection of post Amato cases to illustrate the shortcomings of the Amato approach. In Part V, this note will scrutinize the ideological split on the Ohio Supreme Court regarding the definition of special proceedings and its influence on special proceedings jurisprudence. In Part VI, this note will analyze Ohio\u27s approach to the special proceedings prong of the final judgment rule and suggest an alternative. Lastly, this note will discuss the Ohio Supreme Court\u27s most recent decisions concerning special proceedings

The definitive version was published in Developmental Dynamics 243 (2014): 1646–1657, doi:10.1002/dvdy.24208.Idiopathic scoliosis is a form of spinal deformity that affects 2–3% of children and results in curvature of the spine without structural defects of the vertebral units. The pathogenesis of idiopathic scoliosis remains poorly understood, in part due to the lack of a relevant animal model. We performed a forward mutagenesis screen in zebrafish to identify new models for idiopathic scoliosis. We isolated a recessive zebrafish mutant, called skolios, which develops isolated spinal curvature that arises independent of vertebral malformations. Using meiotic mapping and whole genome sequencing, we identified a nonsense mutation in kinesin family member 6 (kif6gw326) unique to skolios mutants. Three additional kif6 frameshift alleles (gw327, gw328, gw329) were generated with transcription activator-like effector nucleases (TALENs). Zebrafish homozygous or compound heterozygous for kif6 frameshift mutations developed a scoliosis phenotype indistinguishable from skolios mutants, confirming that skolios is caused by the loss of kif6. Although kif6 may play a role in cilia, no evidence for cilia dysfunction was seen in kif6gw326 mutants. Overall, these findings demonstrate a novel role for kif6 in spinal development and identify a new candidate gene for human idiopathic scoliosis.2015-11-1

International journalism and the emergence of transnational publics: between cosmopolitan norms, the affirmation of identity and market forces

Much has been written about transnational public spheres, though our understanding of their shape and nature remains limited. Drawing on three alternative conceptions of newswork as public communication, this article explores the role of international journalists in shaping transnational publics. Based on a series of original interviews, it asks how journalists are oriented in their newswork (e.g. are they cosmopolitan or parochial in their orientation) and how they ‘imagine’ the public. It finds that interviewees imagine a polycentric transnational public and variously frame their work as giving voice to those affected by an issue (imagining the public as a cosmopolitan community of fate), performing and reaffirming a particular kind of identity and belonging (imagining the public as a nation) or pursuing audiences wherever they may be (imagining the public as the de facto audience)

Oh, Jeremy Corbyn! Why did Labour Party membership soar after the 2015 general election?

This article investigates the remarkable surge in individual membership of the Labour Party after the general election of May 2015, particularly after Jeremy Corbyn was officially nominated as a candidate for the leadership in June of that year. Using both British Election Study and Party Members Project data, we explain the surge by focussing on the attitudinal, ideological and demographic characteristics of the members themselves. Findings suggest that, along with support for the leader and yearning for a new style of politics, feelings of relative deprivation played a significant part: many ‘left-behind’ voters (some well-educated, some less so) joined Labour for the first time when a candidate with a clearly radical profile appeared on the leadership ballot. Anti-capitalist and left-wing values mattered too, particularly for those former members who decided to return to the party

A Network of Epigenetic Regulators Guide Developmental Hematopoiesis In Vivo

The initiation of cellular programs is orchestrated by key transcription factors and chromatin regulators that activate or inhibit target gene expression. To generate a compendium of chromatin factors that establish the epigenetic code during developmental hematopoiesis, a large-scale reverse genetic screen was conducted targeting orthologs of 425 human chromatin factors in zebrafish. A set of chromatin regulators was identified that target different stages of primitive and definitive blood formation, including factors not previously implicated in hematopoiesis. We identified 15 factors that regulate development of primitive erythroid progenitors and 29 factors that regulate development of definitive stem and progenitor cells. These chromatin factors are associated with SWI/SNF and ISWI chromatin remodeling, SET1 methyltransferase, CBP/P300/HBO1/NuA4 acetyltransferase, HDAC/NuRD deacetylase, and Polycomb repressive complexes. Our work provides a comprehensive view of how specific chromatin factors and their associated complexes play a major role in the establishment of hematopoietic cells in vivo

Management and resistance in the digital newsroom

What happens when there is conflict between the profit motivations of a news outlet and the professional values of its journalists? Questions of managerial influence and journalistic autonomy have interested media scholars from the seminal work of Warren Breed onwards. However, there have only been a handful of studies since the introduction of audience metrics which, this research suggests, allow managers to more efficiently monitor and discipline their journalists. This article presents an ethnographic case study of a Reuters newswire bureau during a time of conflict between the management and journalists. The article outlines the strategies that management used to incentivize their journalists to change their reporting priorities. These included the strategic dissemination of audience metrics and praise, and the hiring and promotion of ‘appropriate’ journalists to positions of influence. These interventions changed who was considered a ‘good journalist’ at the newswire, disrupting existing hierarchies, and eventually changing the culture of the newsroom. The article draws on the insights of Pierre Bourdieu’s field theory to help explain how managerial power operates, and the role that individual journalists play producing and reinforcing newsroom norms

Application of isothermal titration calorimetry in evaluation of protein–nanoparticle interactions

Nanoparticles (NPs) offer a number of advantages over small organic molecules for controlling protein behaviour inside the cell. Protein binding to the surface of NPs depends on their surface characteristics, composition and method of preparation (Mandal et al. in J Hazard Mater 248–249:238–245, 2013). It is important to understand the binding affinities, stoichiometries and thermodynamical parameters of NP–protein interactions in order to see which interaction will have toxic and hazardous consequences and thus to prevent it. On the other side, because proteins are on the brink of stability, they may experience interactions with some types of NPs that are strong enough to cause denaturation or significantly change their conformations with concomitant loss of their biological function. Structural changes in the protein may cause exposure of new antigenic sites, “cryptic” peptide epitopes, potentially triggering an immune response which can promote autoimmune disease (Treuel et al. in ACS Nano 8(1):503–513, 2014). Mechanistic details of protein structural changes at NP surface have still remained elusive. Understanding the formation and persistence of the protein corona is critical issue; however, there are no many analytical methods which could provide detailed information about the NP–protein interaction characteristics and about protein structural changes caused by interactions with nanoparticles. The article reviews recent studies in NP–protein interactions research and application of isothermal titration calorimetry (ITC) in this research. The study of protein structural changes upon adsorption on nanoparticle surface and application of ITC in these studies is emphasized. The data illustrate that ITC is a versatile tool for evaluation of interactions between NPs and proteins. When coupled with other analytical methods, it is important analytical tool for monitoring conformational changes in proteins
