Tangled bylines : a father and son cover the twentieth century
\"This memoir of father and son journalists-both named Clyde Farnsworth-draws on the unfinished autobiography of the author's father. Largely biographical, this book can be read as a panoramic history of American newspaper journalism in the twentieth-century, covering Prohibition gangs, prison fires, and botched executions in the 1920s and 1930s, to global war, the shaping of postwar Europe and Asia, and America's emergence from the Cold War\" -- provided by publisher.

Agreement Between the Smartphone Application Farnsworth D-15 Test and the Standard Farnsworth D-15 Test for Color Vision Assessment
The primary aim of this study was to evaluate the level of agreement in color vision assessment between the smartphone application Farnsworth D-15 (FD-15) test and the standard FD-15 test.
A cross-sectional study was conducted involving participants aged ≥ 18 years. Inclusion criteria included the ability to follow test instructions and provide informed consent. Eyes with visual acuity worse than 20/200 were excluded. Standardized score sheets were used for both tests to calculate the color confusion index (CCI). Agreement between the two tests was assessed using the Pearson correlation coefficient, adjusted R-squared (R
), calibration slope, calibration-in-the-large (CITL), and root mean square error (RMSE), and Bland-Altman plots.
A total of 200 eyes from 101 participants were included in the study. The CCI data showed a strong correlation (Pearson correlation coefficient = 0.9924). The adjusted
of 0.9839 indicated high explanatory power. A calibration slope of 0.9861 and CITL of 0.0957 indicated minimal proportional and systematic bias, respectively. RMSE was 0.1211, within acceptable limits. The Bland-Altman analysis demonstrated limits of agreement within clinically acceptable range.
The smartphone application FD-15 test demonstrated high agreement with the standard FD-15 test. This study serves as a pilot validation demonstrating the potential of the smartphone-based FD-15 application for color vision screening. However, the current findings should be interpreted considering the use of a single smartphone model and the low prevalence of color vision defects. These findings support its potential utility as a practical and accessible tool for remote care and occupational health assessments.

\Guárdalo como es debido y todo irá bien\
La exposición \"Edith Farnsworth, Reconsidered\" [Edith Farnsworth, replanteada], visitable desde marzo de 2020 hasta diciembre de 2021, presenta la Casa Farnsworth (Ludwig Mies van der Rohe, Plano, Illinois, 1951) tal como fue habitada por la clienta y muestra al público por primera vez la historia vivida de la vivienda. Se centra en el periodo 1951-1954, poco después de que la Dra. Farnsworth tomara posesión de ella y justo antes de que una inundación destruyera el mobiliario interior de estos años, y recorre así unos años de incertidumbre: en 1951, Mies van der Rohe inició el proceso judicial Van der Rohe contra Farnsworth (1951-1955), en el que demandaba a su antigua clienta por unas facturas pendientes y le reclamaba la titularidad de la construcción. Este artículo recorre la cronología de ese juicio hasta su desenlace y considera que la exposición temporal y el expediente del juicio, celosamente custodiado, son dos artefactos con muchos puntos en común: ambos se refieren a unos hechos coincidentes en el tiempo y también ambos han sido \"censurados\" por las instituciones con el objetivo de salvaguardar el patriarcal legado del arquitecto. La censura, en este caso, no es definitiva: es el augurio de otras historias que pueden ser liberadas de las instituciones que las amarran.

Deposition, Diagenesis, and Sequence Stratigraphy of the Pennsylvanian Morrowan and Atokan Intervals at Farnsworth Unit
Farnsworth Field Unit (FWU), a mature oilfield currently undergoing CO2-enhanced oil recovery (EOR) in the northeastern Texas panhandle, is the study area for an extensive project undertaken by the Southwest Regional Partnership on Carbon Sequestration (SWP). SWP is characterizing the field and monitoring and modeling injection and fluid flow processes with the intent of verifying storage of CO2 in a timeframe of 100–1000 years. Collection of a large set of data including logs, core, and 3D geophysical data has allowed us to build a detailed reservoir model that is well-grounded in observations from the field. This paper presents a geological description of the rocks comprising the reservoir that is a target for both oil production and CO2 storage, as well as the overlying units that make up the primary and secondary seals. Core descriptions and petrographic analyses were used to determine depositional setting, general lithofacies, and a diagenetic sequence for reservoir and caprock at FWU. The reservoir is in the Pennsylvanian-aged Morrow B sandstone, an incised valley fluvial deposit that is encased within marine shales. The Morrow B exhibits several lithofacies with distinct appearance as well as petrophysical characteristics. The lithofacies are typical of incised valley fluvial sequences and vary from a relatively coarse conglomerate base to an upper fine sandstone that grades into the overlying marine-dominated shales and mudstone/limestone cyclical sequences of the Thirteen Finger limestone. Observations ranging from field scale (seismic surveys, well logs) to microscopic (mercury porosimetry, petrographic microscopy, microprobe and isotope data) provide a rich set of data on which we have built our geological and reservoir models.

A comprehensive experimental study on the mechanisms of waterflood inefficiency in a Morrowan sandstone reservoir
An indispensable factor in developing improved enhanced oil recovery (EOR) is the in-depth insight into the fractional flow mechanistic effects of waterflood performance, especially for an inefficient waterflood operated field. In this study, the inefficiency of waterflood on the Farnsworth Field Unit (FWU) is investigated. The field is divided into two halves (East and West) of the same reservoir with similar geological characteristics. Though the east was prolific on primary recovery, it failed on waterflood, while the west performed efficiently. Through core-flood experiments, fluid–fluid surface charge tests, and rock-fluid surface chemistry analysis, the causative mechanisms are unraveled. X-ray diffraction (XRD), scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDS) analyses were also conducted to assess mineral composition, pore characteristics and distribution. The core samples exhibited extremely low permeability, resulting in a drastic reduction in flow capacity. Single-phase injection of low salinity water (SIIW) further reduced permeability and increased differential pressure compared to high salinity water (SCW). pH and effluent ionic compositions showed a high reactivity within the rock samples. Fine migrations, clay swelling, scaling, and precipitation were identified as key causes of formation damage during low salinity water flooding. Surface charge and compatibility tests revealed fluid–fluid and rock-fluid reactivity and scale formation influenced by high ionic concentrations, temperature, and pressure. Geochemical analysis indicated aragonite, calcite, and dolomite precipitation under reservoir conditions. Element-mineral identification analysis revealed clays and mineral particles obstructing pores and pore throats. Thus, the principal mechanisms of waterflood inefficiency include low permeability, clay mineral reactivity and fluid incompatibility. These factors collectively contribute to formation damage pore and reduced flow capacity. These insights contribute to the development of effective and improved recovery strategies for incremental recovery from the FWU-east field and addition of new knowledge to existing information on low salinity waterflooding on a Morrowan sandstone.
