Effects of limeted irrigation on the composition of must and wine of Cabernet Sauvignon under semi-arid conditions

Effects of irrigation were studied in a Cabernet Sauvignon vineyard in the Priorat region of Spain, in order to determine the effect of sprinkler irrigation on fruit ripening as well as on must and wine composition. The soil water potential was measured at different depths and irrigation was started when the soil water potential decreased to -1480 kPa. At this point, moderate doses of water (25 l/vine) were added every fortnight during July and August. The yield of the irrigated vines increased by 20%. The must obtained from irrigated vines showed higer levels of potassium than that of the non-irrigated vines. Total soluble solids increased earlier and more rapidly in irrigated vines. We also found higher levels of malic acid and the total acidity increased in both, must and wine. However, tannins and anthocyanins, were lower in wines of irrigated grapevines. The later result is possible due to a rainfall which occurred before harvest, since phenolics did not decresase when a similar irrigation was applied in subsequent years

Infographic Assignment

Curatorial note from Digital Pedagogy in the Humanities: Infographics are visual representations of information or data and provide an interesting way of considering how design affects the ways information is understood. The decision to represent wealth inequality through a line graph as opposed to icons of people drawn to scale to represent average salary speaks to issues of purpose and audience and is an engaging way to help students see the rhetorical role of design. In this assignment, Bill Wolff asks his students to engage with Edward Tufte’s and Ellen Lupton’s theories of design, typography, and evidence presentation through creating infographics with Piktochart (a free online infographic creator). Along with producing an infographic, students write a reflection in which they describe their objective, rhetorical strategies, and the ways in which they engaged with Tufte and Lupton’s theories of information design. While we have categorized this assignment under “Producing Design,” it includes a nice balance of both producing and reflecting, thus encouraging critical self-reflection

Immunohistochemical Expression of Somatostatin Receptor Subtypes in a Panel of Neuroendocrine Neoplasias

Neuroendocrine neoplasias (NENs) are known to express somatostatin receptors (SSTRs) 1-5, which are G-protein-coupled cell membrane receptors. Somatostatin receptor imaging and therapy utilizes the SSTR expression. Synthetic somatostatin analogs with radioligands are used to detect primary tumors, metastases, and recurrent disease. Receptor analogs are also used for treating NENs. Furthermore, commercially available SSTR antibodies can be used for the immunohistochemical (IHC) detection of SSTRs. We investigated different SSTR antibody clones applying diverse IHC protocol settings to identify reliable clones and feasible protocols for NENs. A tissue microarray including NENs from 12 different primary sites were stained. Only UMB clones were able to localize SSTR on the cell membranes of NENs. SSTR2 (UMB1) emerged as the most common subtype followed by SSTR5 (UMB4) and SSTR1 (UMB7). SSTR3 (UMB5) expression was mainly cytoplasmic. Yet, SSTR4 expression was weak and located primarily in the cytoplasm. Thus, appropriate IHC protocols, including proper positive and negative controls, represent requirements for high-quality NEN diagnostics and for planning personalized therapy.Peer reviewe

Visual Communication Audit

Curatorial note from Digital Pedagogy in the Humanities: Focused on the professional writing classroom, this assignment asks students to identify an organization or company and to perform a visual audit. Students gather external communication (posters, flyers, handouts, reports, media releases, etc.) from the company or organization and analyze the work the visual aspects of these texts perform. The assignment allows students to explore how design choices help shape the message of a business or organization

Analyzing Visual and Multimodal Rhetorics in Monuments and Memorials

Curatorial note from Digital Pedagogy in the Humanities: This multistep assignment asks students to select and analyze a monument or memorial of their choice. After completing several readings on visual, spatial, and performative rhetoric, student teams visit their chosen artifact (or review it online if it is not local) and complete a systematic analysis of its physical, contextual, and commemorative elements and present their findings to the rest of the class. As material objects, the design of monuments and memorials call viewers’ attention to not only visual symbols but also issues of location, kairos, absence, and audience interaction. That is, this analysis asks students to evaluate the multitude of ways the designer(s) created meaning and encouraged viewer participation in commemorative acts

Relativistic theory of magnetic scattering of x rays: Application to ferromagnetic iron

We present a detailed description of a first-principles formalism for magnetic scattering of circularly polar- ized x rays from solids in the framework of the fully relativistic spin-polarized multiple-scattering theory. The scattering amplitudes are calculated using a standard time-dependent perturbation theory to second order in the electron-photon interaction vertex. Particular attention is paid to understanding the relative importance of the positive- and negative-energy solutions of the Dirac equation to the scattering amplitude. The advantage of the present theory as compared with other recent works on magnetic x-ray scattering is that, being fully relativistic, spin-orbit coupling and spin-polarization effects are treated on an equal footing. Second, the electron Green’s function expressed in terms of the path operators in the multiple-scattering theory allows us to include the contribution of the crystalline environment to the scattering amplitude. To illustrate the use of the method we have done calculations on the anomalous magnetic scattering at the K , L_II , and L_III absorption edges of ferromagnetic iron

Remix a Story

Curatorial note from Digital Pedagogy in the Humanities: Assignments focused on redesigning texts ask students to consider how the design of a text encourages a certain understanding of that text. In this assignment, Traci Gardner asks her students to take an existing story told through the written word and translate it into a multimodal version. By asking students to think creatively about how to redesign and represent text in a new format, students must consider how the design choices they make have rhetorical effects. This assignment can be used in literature courses as a way of interrogating how a story is told, shaped, read, and understood through the modal choices used

Multimodal Rhetorical Analysis

Curatorial note from Digital Pedagogy in the Humanities: While the first two artifacts in this list look more specifically at design, this assignment folds design into a multimodal rhetorical analysis assignment. It also asks students to specifically consider how the analysis work they are doing can lead to a list of best practices for their own productions. Encouraging students to dig deeply within design analyses while also considering how those analyses can contribute to their own design practices is key in fostering a discursive understanding of design within digital pedagogy. Similar to how we ask students to analyze writing in the hopes they become more critical about reading and writing, this assignment asks students to analyze a multimodal text so as to become more critical about the multimodal texts they produce. More specifically, it asks them to take stock of the most effective strategies they encounter and produce a list of best practices for their own designs. This assignment helps make a bridge from analysis to production
