Native Speakers Do Not Understand Me : A Phenomenological Study of Student Experiences from Developing Asian Countries at an American University

International students from developing Asian countries where English is the second and foreign language are marginalized in some American Universities due to language barriers. Native English speakers often assume that whoever comes to the United States should be able to speak and write English perfectly. In developing Asian countries, such as South Asia, however, the English language belongs to the families of the Middle and Upper classes. They can get admission in English spoken countries’ higher education institutions. However, when those students come to English-speaking countries, they feel othered, left alone, and disappointed. This study utilizes a phenomenological research method to tell thestudents\u27 lived experiences from several Asian countries, including some isolated nations. Specifically, this study focuses on the writing challenges of students and how they utilize the limited resources to help them succeed

Intrinsic switching field distribution of arrays of Ni80Fe20 nanowires probed by in situ\mathit{in\, situ} magnetic force microscopy

The progress of magnetization reversal of weakly packed ferromagnetic Ni80Fe20 nanowire arrays of different diameters (40, 50, 70 and 100 nm) electrodeposited in polycarbonate membranes was studied by magnetic force microscopy (MFM). For such a low packing density of nanomagnets, the dipolar interactions between neighbouring wires can be neglected. The intrinsic switching field distribution has been extracted from in situ MFM images and its width was found to be considerably smaller than for densely packed nanowire arrays.Comment: 4 pages, 5 figures.

Magnetic force microscopy investigation of arrays of nickel nanowires and nanotubes

The magnetic properties of arrays of nanowires (NWs) and nanotubes (NTs), 150 nm in diameter, electrodeposited inside nanoporous polycarbonate membranes are investigated. The comparison of the nanoscopic magnetic force microscopy (MFM) imaging and the macroscopic behavior as measured by alternating gradient force magnetometry (AGFM) is made. It is shown that MFM is a complementary technique that provides an understanding of the magnetization reversal characteristics at the microscopic scale of individual nanostructures. The local hysteresis loops have been extracted by MFM measurements. The influence of the shape of such elongated nanostructures on the dipolar coupling and consequently on the squareness of the hysteresis curves is demonstrated. It is shown that the nanowires exhibit stronger magnetic interactions than nanotubes. The non-uniformity of the magnetization states is also revealed by combining the MFM and AGFM measurements.Comment: 7 pages, 5 figure

Magnetic force microscopy study of the switching field distribution of low density arrays of single domain magnetic nanowires

In the present work, we report on the in situ magnetic force microscopy (MFM) study of the magnetization reversal in two-dimensional arrays of ferromagnetic Ni80Fe20 and Co55Fe45 nanowires(NW) with different diameters (40, 50, 70 and 100 nm) deposited inside low porosity (P<1%) nanoporous polycarbonate membranes. In such arrays, the nanowires are sufficiently isolated from each other so that long range dipolar interactions can be neglected. The MFM experiments performed for different magnetization states at the same spot of the samples are analysed to determine the switching field distribution (SFD). The magnetization curves obtained from the MFM images are relatively square shaped. The SFD widths are narrower compared to those obtained for high density arrays. The weak broadening of the curves may be ascribed to the NW intrinsic SFD. The influence of diameter and composition of the ferromagnetic NW is also investigated.Comment: 6 pages, 4 figures, To appear in Journal of Applied Physic

A nationwide study of adults admitted to hospital with diabetic ketoacidosis or hyperosmolar hyperglycaemic state and COVID‐19

AimsTo investigate characteristics of people hospitalized with coronavirus-disease-2019 (COVID-19) and diabetic ketoacidosis (DKA) or hyperosmolar hyperglycaemic state (HHS), and to identify risk factors for mortality and intensive care admission.Materials and methodsRetrospective cohort study with anonymized data from the Association of British Clinical Diabetologists nationwide audit of hospital admissions with COVID-19 and diabetes, from start of pandemic to November 2021. The primary outcome was inpatient mortality. DKA and HHS were adjudicated against national criteria. Age-adjusted odds ratios were calculated using logistic regression.ResultsIn total, 85 confirmed DKA cases, and 20 HHS, occurred among 4073 people (211 type 1 diabetes, 3748 type 2 diabetes, 114 unknown type) hospitalized with COVID-19. Mean (SD) age was 60 (18.2) years in DKA and 74 (11.8) years in HHS (p < .001). A higher proportion of patients with HHS than with DKA were of non-White ethnicity (71.4% vs 39.0% p = .038). Mortality in DKA was 36.8% (n = 57) and 3.8% (n = 26) in type 2 and type 1 diabetes respectively. Among people with type 2 diabetes and DKA, mortality was lower in insulin users compared with non-users [21.4% vs. 52.2%; age-adjusted odds ratio 0.13 (95% CI 0.03-0.60)]. Crude mortality was lower in DKA than HHS (25.9% vs. 65.0%, p = .001) and in statin users versus non-users (36.4% vs. 100%; p = .035) but these were not statistically significant after age adjustment.ConclusionsHospitalization with COVID-19 and adjudicated DKA is four times more common than HHS but both associate with substantial mortality. There is a strong association of previous insulin therapy with survival in type 2 diabetes-associated DKA

Climate Change and Impacts of Extreme Events on Human Health: an Overview

The causes of climate patchy rope in heat up temperature, change in precipitation, degree of utmost conditions occasions like melting of glaciers, polar ice-caps, mount in sea levels, etc. These impacts eventually fall our income by touching the rations we eat, the water we drink, the air we breathe and the earth somewhere we live. Frequent impacts caused fitting to excessive exposure of heat waves such as round stroke, dehydration, cardiovascular, respiratory and neural comborbidities. Climate conversion alters the ecology of vectors and these vectors are capable of have in stock causal agents such as viruses, bacteria and protozoa from animals to humans. Malaria, tick-borne encephalitis, fair fever, plague, and dengue obtain lengthened their geographical ranges as their carriers migrated to privileged latitudes. Droughts canister take part in adverse property on being health, as they over and over again suggest itself in mishmash with other sit out conditions, such as warm waves, wildfires and dust storms. Reduced water quantity may cause decreased water flow during periods of drought, encouraging the development of pathogens which prefer dry, stagnant environments. Altering climatic situation know how to be attributed to mounting International temperatures, spread in the dimensions of ambient fill up fumes and changes in the announce motion as mutual together. Extreme season and climate-related actions are famous to set off fundamental infrastructure failures, lucrative harm and relocation of communities, ensuing in a quantity of health problems
