Tunable far infrared studies of molecular parameters in support of stratospheric measurements

Lab studies were made in support of far infrared spectroscopy of the stratosphere using the Tunable Far InfraRed (TuFIR) method of ultrahigh resolution spectroscopy and, more recently, spectroscopic and retrieval calculations performed in support of satellite-based atmospheric measurement programs: the Global Ozone Monitoring Experiment (GOME), and the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY)

Quinhydrone Chemical Passivation of a Silicon Surface for Minority Carrier Bulk-Lifetime Measurements

For the measurement of the minority carrier bulk-lifetime the characterization method MW-PCD is used, where the result of measurement is the effective carrier lifetime, which is very dependent on the surface recombination velocity and therefore on the quality of a silicon surface passivation. This work deals with an examination of a different solution types for the chemical passivation of a silicon surface. Various solutions are tested on silicon wafers for their consequent comparison. The main purpose is to find optimal solution, which suits the requirements of a time stability and start-up velocity of passivation, reproducibility of the measurements and a possibility of a perfect cleaning of a passivating solution remains from a silicon surface, so that the parameters of a measured silicon wafer will not worsen and there will not be any contamination of the other wafers series in the production after a repetitive return of the measured wafer into the production process. The cleaning process itself is also a subject of a development

A new electron diffraction approach for structure refinement applied to Ca3Mn2O7

The digital large-angle convergent-beam electron diffraction (D-LACBED) technique is applied to Ca3Mn2O7 for a range of temperatures. Bloch-wave simulations are used to examine the effects that changes in different parameters have on the intensity in D-LACBED patterns, and atomic coordinates, thermal atomic displacement parameters and apparent occupancy are refined to achieve a good fit between simulation and experiment. The sensitivity of the technique to subtle changes in structure is demonstrated. Refined structures are in good agreement with previous determinations of Ca3Mn2O7 and show the decay of anti-phase oxygen octahedral tilts perpendicular to the c axis of the A21am unit cell with increasing temperature, as well as the robustness of oxygen octahedral tilts about the c axis up to ∼400°C. The technique samples only the zero-order Laue zone and is therefore insensitive to atom displacements along the electron-beam direction. For this reason it is not possible to distinguish between in-phase and anti-phase oxygen octahedral tilting about the c axis using the [110] data collected in this study

Hospital Nutrition Assessment Practice 2016 Survey

BackgroundMalnutrition is a significant problem for hospitalized patients in the United States. Nutrition assessment is an important step in recognizing malnutrition; however, it is not always performed using consistent parameters.MethodsA survey among U.S. American Society for Parenteral and Enteral Nutrition (ASPEN) members was conducted to collect data on nutrition assessment parameters used in hospitals and to establish how facilities use their electronic health record (EHR) to permit data retrieval and outcome reporting.ResultsThe survey was developed by the ASPEN Malnutrition Committee and was sent to 5487 U.S. ASPEN members, with 489 responding for a 9% response rate. Ninety‐eight percent of adult and 93% of pediatric respondents indicated a registered dietitian completed the nutrition assessment following a positive nutrition screen. Variables most frequently used among adult respondents included usual body weight, ideal body weight, and body mass index. Among pediatric respondents, weight‐for‐age and height‐for‐age percentiles and length/height‐for‐age percentile were most frequently used. Both adult and pediatric respondents indicated use of physical assessment parameters, including muscle and fat loss and skin assessment. Eighty‐seven percent of adult and 77% of pediatric respondents indicated they are using the Academy of Nutrition and Dietetics (Academy) and ASPEN Consensus Malnutrition Characteristics for Adult and Pediatric Malnutrition, respectively. Overall, 97% of respondents indicated nutrition assessment documentation was completed via an EHR. Of all respondents, 61% indicated lack of clinical decision support within their EHR.ConclusionThis survey demonstrated significant use of the Academy/ASPEN malnutrition consensus characteristics.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146497/1/ncp10179_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146497/2/ncp10179.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146497/3/ncp10179-sup-0001-FigureS1.pd

Inflammatory fibroid polyp of the ileum presenting with small bowel obstruction in an adult patient: a case report

<p>Abstract</p> <p>Introduction</p> <p>Inflammatory fibroid polyps are rare benign tumors of the gastrointestinal tract with the gastric antrum being the most common site, followed by the ileum. Histogenesis is still unknown and controversial. Inflammatory fibroid polyps are one of the rare benign conditions leading to intestinal obstruction in adults.</p> <p>Case presentation</p> <p>A 54-year-old Caucasian man presented with acute abdomen pain and a two month history of intermittent cramping and lower abdominal pain. Computed tomography imaging demonstrated a partial intestinal obstruction in the location of the terminal ileum. An ileo-ileal intussusception due to a mass lesion 15 cm proximal to the caecum was found on exploratory laparotomy. Intussusception was spontaneously reduced during exploration and a wedge resection was performed to the affected bowel segment. Histopathologic examination showed the mass to be an inflammatory fibroid polyp.</p> <p>Conclusion</p> <p>Although inflammatory fibroid polyps are rare and benign, in the case of intestinal obstruction the only solution is a surgical approach.</p

Communitarian perspectives on social enterprise

Concepts of social enterprise have been debated repeatedly, and continue to cause confusion. In this paper, a meta-theoretical framework is developed through discussion of individualist and communitarian philosophy. Philosophers from both traditions build social theories that emphasise either consensus (a unitarist outlook) or diversity (a pluralist outlook). The various discourses in corporate governance reflect these assumptions and create four distinct approaches that impact on the relationship between capital and labour. In rejecting the traditional discourse of private enterprise, social enterprises have adopted other approaches to tackle social exclusion, each derived from different underlying beliefs about the purpose of enterprise and the nature of governance. The theoretical framework offers a way to understand the diversity found within the sector, including the newly constituted Community Interest Company (CIC).</p
