Unilateral abdominal clonic seizures represent a peculiar and rare manifestation of focal onset epilepsy. We present the case of a 26‐year‐old man with right‐sided abdominal clonic movements associated with seizures arising from the left parietal area. We show the ictal EEG correlates of these events, including source localization of early ictal spikes; findings that have not been demonstrated in previously reported cases. The electro‐clinical features in this patient suggested that clinical onset occurred after anterior propagation of ictal activity from a region posterior to the neck and trunk area of the sensory homunculus of the postcentral gyrus.

AbstractOn June 28, 2013, the Food Safety and Inspection Service (FSIS) was notified by the Centers for Disease Control and Prevention (CDC) of an investigation of a multistate cluster of illnesses of Salmonella entericaserovar Heidelberg. Since case-patients in the cluster reported consumption of a variety of chicken products, FSIS used a simple likelihood-based approach using traceback information to focus on intensified sampling efforts. This article describes the multiphased product sampling approach taken by FSIS when epidemiologic evidence implicated chicken products from multiple establishments operating under one corporation. The objectives of sampling were to (1) assess process control of chicken slaughter and further processing and (2) determine whether outbreak strains were present in products from these implicated establishments. As part of the sample collection process, data collected by FSIS personnel to characterize product included category (whole chicken and type of chicken parts), brand, organic or conventional product, injection with salt solutions or flavorings, and whether product was skinless or skin-on. From the period September 9, 2013, through October 31, 2014, 3164 samples were taken as part of this effort. Salmonellapercent positive declined from 19.7% to 5.3% during this timeframe as a result of regulatory and company efforts. The results of intensified sampling for this outbreak investigation informed an FSIS regulatory response and corrective actions taken by the implicated establishments. The company noted that a multihurdle approach to reduce Salmonellain products was taken, including on-farm efforts such as environmental testing, depopulation of affected flocks, disinfection of affected houses, vaccination, and use of various interventions within the establishments over the course of several months.

AbstractThis roundtable was conducted by the eight founding members of Decolonising Design Group in October 2017, using an online messaging platform. Each member approached design and decoloniality from different yet interrelating viewpoints, by threading their individual arguments with the preceding ones. The piece thus offers and travels through a variety of subject matter including politics of design, artificiality, modernity, Eurocentrism, capitalism, Indigenous Knowledge, pluriversality, continental philosophy, pedagogy, materiality, mobility, language, gender oppression, sexuality, and intersectionality.

AbstractThis study focuses on the development of design correlation for pressure drop in wire mesh demisters, used in the multistage flash desalination process (MSF) as well as similar evaporation and flashing units found in other industrial processes. Development of the correlation is based on numerical simulation of the demister using steady-state and two-dimensional model for the flow of vapor and brine droplets through the demister. An Eulerian model was used to model the system and the resulting model equations were solved using a commercial computational fluid dynamics software (FLUENT). The system model was formed of three zones, which include the vapor space above and below the demister and the demister. In addition, the demister was approximated as a porous media. A sensitivity analysis of the model revealed that vapor velocity, demister packing density and height, and the inlet flashed-off vapor composition are the main parameters that affect demister performance. Consequently, numerical data were used to correlate pressure drop across the demister as a function of operating and design parameters. The developed correlation was validated using data from real MSF plants. Analysis indicated that the correlation predictions and experimental data were consistent and showed good agreement with an error less than 25%.
