Among the pertinent differentials for hypercalcemia, milk-alkali syndrome remains a diagnosis of exclusion following a thorough workup of other severe causes. However, several key signs may increase a clinician's index of suspicion for possible milk-alkali syndrome, including a prolonged history of antacid ingestion. Milk-alkali syndrome commonly presents with a classic triad: hypercalcemia, metabolic alkalosis, and acute kidney injury. The diagnostic workup should include evaluation of both serum and urine calcium levels, serum phosphate levels, and other hormones (parathyroid hormone, vitamin D). In the case of a confirmed diagnosis of milk-alkali syndrome, rapid correction of calcium levels is of utmost importance. We present the case and workup of an individual presenting to the emergency room with hypercalcemia, acute kidney injury, and several key systemic symptoms. Given a significant history of antacid overuse, and a thorough diagnostic workup, a diagnosis of milk-alkali syndrome was made and the patient was treated accordingly, making a full recovery. We review this rare case and important clinical pearls regarding milk-alkali syndrome.
In the wake of the global financial crisis and a context of stagnating development aid, the international community now promotes linking remittances to finance as a development strategy, in what has been termed the ‘financialisation of remittances’ (FOR). This article analyses the ways in which the financialisation of remittance manifests in Mexico in gendered ways, and what this tells us about financialisation and financial subjectivation processes beyond the global North. We find that the financialisation of remittance represents a shift from earlier remittance-based development models whereby remittances become linked to financial inclusion and social welfare agendas and the focus is broadened beyond migrant income to diaspora wealth. Focusing on the governing arrangements of the financialisation of remittance, we propose the concept of ‘constellation of subjectivities’ in order to analyse the interrelated and interacting programmatic subjectivities through which the financialisation of remittance manifests in Mexico. Combining this conceptualisation with interdisciplinary feminist insights on financialisation, we analyse the various intersecting social dynamics that weave through such constellations. The analysis – based on document, interview and observation material – finds that the financialisation of remittance in Mexico creates and governs a gendered constellation of financial subjectivities with three dimensions: migrant men, remittance-receiving women and the constitutive outside of the non-transnational family. While most studies tend to focus on transnational families, we demonstrate that non-transnational families are an integral part of the financialisation of remittance. Our analysis destabilises the notion of the universal financial subject and highlights the importance of broadening our analysis of financialisation to constitutive outsides that often fall off the radar.
-The California Institute of Technology's Combustion Acoustics Facility is used to measure the changes in the creation of NO in a partially premixed jet flame due to acoustic forcing at frequencies ranging from 22 to 55 Hz. The facility generates a quarter-wave mode so that the test flame is in a region where the acoustic velocity is nearly zero. This facility and a similar burner have been previously used to measure the phase-resolved response of the OH field. In this experiment, phase-resolved NO planar laserinduced fluorescence (PLIF) measurements are recorded. The location and phase coupling of the NO field are analyzed, and the production and transport of NO are compared with previously reported OH field measurements. The NO levels increase for frequencies that exhibit stronger acoustic coupling to the flame. The NO concentration field variations lead (in phase space) the OH field variations. This is probably a result of the greater NO sensitivity to temperature (which itself is closely coupled to the chamber pressure).
This research investigated the impact of several structured inquiry experiments in mechanics and heat on introductory college physics students' ability to solve or make sense of problem scenarios. The students performed experiments where they were guided in discovering for themselves the physical concepts or principles rather than having them verify concepts/principles as in traditional lab classes. At the end of each laboratory activity, students were asked to answer problem scenarios with solutions or answers requiring a direct application of the physical concepts investigated in the laboratory experiment. Our preliminary results indicate that students are able to use the concepts learned from the laboratory activity in explaining problem scenarios only in some topics (e.g. thermal expansion) but not in other topics (e.g. momentum conservation).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
