A conceptual analytics model for an outcome-driven quality management framework as part of professional healthcare education
BACKGROUND: Preparing the future health care professional workforce in a changing world is a significant undertaking. Educators and other decision makers look to evidence-based knowledge to improve quality of education. Analytics, the use of data to generate insights and support decisions, have been applied successfully across numerous application domains. Health care professional education is one area where great potential is yet to be realized. Previous research of Academic and Learning analytics has mainly focused on technical issues. The focus of this study relates to its practical implementation in the setting of health care education. OBJECTIVE: The aim of this study is to create a conceptual model for a deeper understanding of the synthesizing process, and transforming data into information to support educators’ decision making. METHODS: A deductive case study approach was applied to develop the conceptual model. RESULTS: The analytics loop works both in theory and in practice. The conceptual model encompasses the underlying data, the quality indicators, and decision support for educators. CONCLUSIONS: The model illustrates how a theory can be applied to a traditional data-driven analytics approach, and alongside the context- or need-driven analytics approach

Komposit Beton-profil Lip Channel Untuk Mencegah Tekuk Lateral-torsional
Lip channels profile usually failed before reaching its maximum loaddue to torsional. To avoid this problem, usually lateral support isprovided to the profile. One of the solution is by filling the profile withconcrete material (composite). The purpose of this research is to knowthe bending strength ratio of lip channels profile to lip channels-concretecomposite. The specimens in this research is lip channelsC85x40x8x0.90, C85x40x8x0.65, C75x40x10x0.75, C75x40x10x0.65and two pieces of composite beams of 85x40x1100 mm with two piecesof composite beams 75x40x1100 mm. Beside the bending strength testas the main test, additional test should be runned by concretecompression test using 12 pieces of 150x150x150 cube and 12 pieces oflip channels. Based on this research, it is found that the bending strengthof the lip channels (P-1) and composite beam (K-1) are 262.06 MPa and366.35 MPa each. The result means that there is 1.40 (39.80%)increasing in bending strength. For P-2 the bending strength is 268.64MPa while K-2 is 453.60 MPa or increased 1.69 (68.85%). For P-3bending strength is 180.90 MPa while K-3 is 364.75 MPa, increased 2.02(101.63%). For P-4 the bending strength is 207.59 MPa while K-4 is430.05 MPa, increased 2.07( 107.16%)
Utilizing pHluorin-Tagged Receptors to Monitor Subcellular Localization and Trafficking
Understanding membrane protein trafficking, assembly, and expression requires an approach that differentiates between those residing in intracellular organelles and those localized on the plasma membrane. Traditional fluorescence-based measurements lack the capability to distinguish membrane proteins residing in different organelles. Cutting edge methodologies transcend traditional methods by coupling pH-sensitive fluorophores with total internal reflection fluorescence microscopy (TIRFM). TIRF illumination excites the sample up to approximately 150 nm from the glass-sample interface, thus decreasing background, increasing the signal to noise ratio, and enhancing resolution. The excitation volume in TIRFM encompasses the plasma membrane and nearby organelles such as the peripheral ER. Superecliptic pHluorin (SEP) is a pH sensitive version of GFP. Genetically encoding SEP into the extracellular domain of a membrane protein of interest positions the fluorophore on the luminal side of the ER and in the extracellular region of the cell. SEP is fluorescent when the pH is greater than 6, but remains in an off state at lower pH values. Therefore, receptors tagged with SEP fluoresce when residing in the endoplasmic reticulum (ER) or upon insertion in the plasma membrane (PM) but not when confined to a trafficking vesicle or other organelles such as the Golgi. The extracellular pH can be adjusted to dictate the fluorescence of receptors on the plasma membrane. The difference in fluorescence between TIRF images at neutral and acidic extracellular pH for the same cell corresponds to a relative number of receptors on the plasma membrane. This allows a simultaneous measurement of intracellular and plasma membrane resident receptors. Single vesicle insertion events can also be measured when the extracellular pH is neutral, corresponding to a low pH trafficking vesicle fusing with the plasma membrane and transitioning into a fluorescent state. This versatile technique can be exploited to study localization, expression, and trafficking of membrane proteins

Arkansas Cooperative Beef Bull Performance Test 1991
Performance testing of beef bulls was initiated to improve productivity of Arkansas beef cattle through breeding. This cooperative testing program provides cattlemen with reliable information for identifying animals with superior breeding value for the traits of production measured in the test. By using the information as a basis for herd sire selection, a breeder can greatly increase the chances of obtaining a bull that will sire rapid-gaining, more efficient, highquality calves. Such calves can increase profits for both the breeder and the feeder. This testing program provides information that is useful to financial institutes in arranging their lending programs and to companies in developing their educational, promotional and marketing programs
K-Promoted Ni-Based Catalysts for Gas-Phase CO2 Conversion: Catalysts Design and Process Modelling Validation
The exponential growth of greenhouse gas emissions and their associated climate change
problems have motivated the development of strategies to reduce CO2 levels via CO2
capture and conversion. Reverse water gas shift (RWGS) reaction has been targeted as a
promising pathway to convert CO2 into syngas which is the primary reactive in several
reactions to obtain high-value chemicals. Among the different catalysts reported for
RWGS, the nickel-based catalyst has been proposed as an alternative to the
expensive noble metal catalyst. However, Ni-based catalysts tend to be less active in
RWGS reaction conditions due to preference to CO2 methanation reaction and to the
sintering and coke formation. Due to this, the aim of this work is to study the effect of the
potassium (K) in Ni/CeO2 catalyst seeking the optimal catalyst for low-temperature RWGS
reaction. We synthesised Ni-based catalyst with different amounts of K:Ni ratio (0.5:10, 1:
10, and 2:10) and fully characterised using different physicochemical techniques where
was observed the modification on the surface characteristics as a function of the amount of
K. Furthermore, it was observed an improvement in the CO selectivity at a lower
temperature as a result of the K-Ni-support interactions but also a decrease on the
CO2 conversion. The 1K catalyst presented the best compromise between CO2
conversion, suppression of CO2 methanation and enhancing CO selectivity. Finally, the
experimental results were contrasted with the trends obtained from the thermodynamics
process modelling observing that the result follows in good agreement with the modelling
trends giving evidence of the promising behaviour of the designed catalysts in CO2 highscale units.Ministerio de Ciencia e Innovación PID2019-108502RJ-I00 IJC2019-040560-IMinisterio de Ciencia e Innovación RYC2018-024387-
