Year: 2017

description: This research aims to evaluate the performance of METEC industries/firms with a special emphasizes on METEC manufacturing firms in Addis Ababa, Bushoftu and Adama. This study aimed at assessing performance of the selected FDRE Metals and Engineering Corporation using balanced scorecard as framework. The researcher used quota and convenience sampling methods to select customers and employees as respondents. Based on the developed framework 15 performance indicators categorized under the 4 BSC perspectives. Financial data were used and primary data collected using five scale Likert. The researcher used structured questionnaires and the collected data analyzed using statistical methods. The findings of the study based on FP ratios, the firms ROA and ROE shows that firms do not use their asset and equity efficiently to earn profit. Furthermore, the first three hypothesis result shows BSC perspectives are positively correlated with each other at a statistically significant level and in a sequential way. Results also evidence that the companies that have improved their ROE and ROA had increased their efforts towards characteristics that involve the learning and growth perspective. So, METEC firms/industries suggested paying attention on the use of BSC as a performance measurement tool and also hub to specified performance indicators that needs enhancement.

description: Space asteroseismology is revolutionizing our knowledge of the internal structure and dynamics of stars. A breakthrough is ongoing with the recent discoveries of signatures of strong magnetic fields in the core of red giant stars. The key signature for such a detection is the asymmetry these fields induce in the frequency splittings of observed dipolar mixed gravito-acoustic modes. We investigate the ability of the observed asymmetries of the frequency splittings of dipolar mixed modes to constrain the geometrical properties of deep magnetic fields. We use the powerful analytical Racah-Wigner algebra used in Quantum Mechanics to characterize the geometrical couplings of dipolar mixed oscillation modes with various possible realistic fossil magnetic fields' topologies and compute the induced perturbation of their frequencies. First, in the case of an oblique magnetic dipole, we provide the exact analytical expression of the asymmetry as a function of the angle between the rotation and magnetic axes. Its value provides a direct measure of this angle. Second, considering a combination of axisymmetric dipolar and quadrupolar fields, we show how the asymmetry is blind to unravel the relative strength and sign of each component. Finally, in the case of a given multipole, we show that a negative asymmetry is a signature of non-axisymmetric topologies. Therefore, asymmetries of dipolar mixed modes provide key but only partial information on the geometrical topology of deep fossil magnetic fields. Asteroseismic constraints should therefore be combined with spectropolarimetric observations and numerical simulations, which aim to predict the more probable stable large-scale geometries.

description: This article deals with the enumeration of directed lattice walks on the integers with any finite set of steps, starting at a given altitude $j$ and ending at a given altitude $k$, with additional constraints such as, for example, to never attain altitude $0$ in-between. We first discuss the case of walks on the integers with steps $-h, \dots, -1, +1, \dots, +h$. The case $h=1$ is equivalent to the classical Dyck paths, for which many ways of getting explicit formulas involving Catalan-like numbers are known. The case $h=2$ corresponds to "basketball" walks, which we treat in full detail. Then we move on to the more general case of walks with any finite set of steps, also allowing some weights/probabilities associated with each step. We show how a method of wide applicability, the so-called "kernel method", leads to explicit formulas for the number of walks of length $n$, for any $h$, in terms of nested sums of binomials. We finally relate some special cases to other combinatorial problems, or to problems arising in queuing theory.

description: Disasters are a primary influence in the global development landscape given their unequal impacts across society and calls for transformative change in their aftermath. Recovering from disasters is one component of development that is coming under scrutiny. This is especially so in the context of the COVID-19 pandemic, whose scale, scope, and cascading effects mean that the uncertain prospects for recovery will be complicated and endure long term. COVID-19 has forced a reappraisal of what recovery encompasses, who it is for, and how it can better enable preparedness for future disasters. Drawing upon interviews with a global community of experts specializing in different areas of disaster governance, this paper focuses on the lessons emerging for recovery-related theory and practice deriving from the pandemic. We elaborate a multi-dimensional framework to support those working on local recovery planning within communities and operating across different sectors. The framework captures the interconnected issues across six principal domains—communities, economic, infrastructure, environment, health, and governance—representing key impact areas around which strategies and multifaceted actions can be developed. We suggest a three-step process using a systems approach to develop a recovery strategy that operationalizes the framework and addresses the complexity of long-term recovery for development.
Why “Go Vote” is not enough an animated short about stuff they didn’t teach you in Texas civics class

description: Political parties, celebrities, non-profits, and prior generations have only one message for members of Gen Z: “Go Vote.” It’s not bad advice, but it doesn’t acknowledge the realities of voter suppression and gerrymandering in Texas, nor does it help young Texans understand why their votes never seem to make a difference. Worse, civics education in Texas schools is intentionally designed to conceal how and why Texas’s voting laws and systems, such as winner-take-all ballots and redistricting, maintain minority rule. I have created an animated short called Bop or Flop, whose humorous game-show format is designed to fill important gaps in Texas civics education and alert Gen Z Texans to how gerrymandering shapes political outcomes in Texas. "Bop or Flop: Old vs. New Gerrymanderers" highlights the lunacy behind America's continued use of a system created two hundred years ago by contrasting the moral and technological evolutions made in other dimensions of American life with the systems politicians use to draw redistricting maps, which have stayed largely the same. With the explicit intent to connect with young Texans, “Bop or Flop” shows how issues that Gen-Z voters care about (e.g., women’s autonomy, LGBTQIA+ rights, the environment, etc.) are affected by Texas’s redistricting process, and satirizes the “values” of legislators who deliberately subvert the principle of majority rule by redrawing districts to maintain their hold on power. I envision this segment as the first in a series of animations highlighting how structural and systemic inequities in the Texas political process negatively impact young Texans’ lives.
Exploring the Evolution of Massive Clumps in Simulations that Reproduce the Observed Milky Way α-element Abundance Bimodality

description: The Milky Way stellar disk has both a thin and a thick component. The thin disk is composed mostly of younger stars ($\lesssim$8 Gyr) with a lower abundance of $α$ elements, while the thick disk contains predominantly older stars ($\gtrsim$8--12 Gyr) with a higher $α$ abundance, giving rise to an $α$-bimodality most prominent at intermediate metallicities. A proposed explanation for the bimodality is an episode of clumpy star formation, where high-$α$ stars form in massive clumps that appear in the first few Gyrs of the Milky Way's evolution, while low-$α$ stars form throughout the disk and over a longer time span. To better understand the evolution of clumps, we track them and their constituent stars in two clumpy Milky Way simulations that reproduce the $α$-abundance bimodality, one with 10% and the other with 20% supernova feedback efficiency. We investigate the paths that these clumps take in the chemical space ([O/Fe]--[Fe/H]) as well as their mass, star formation rate (SFR), formation location, lifetime, and merger history. The clumps in the simulation with lower feedback last longer on average, with several lasting hundreds of Myr. Some of the clumps do not reach high-$α$, but the ones that do on average had a higher SFR, longer lifetime, greater mass, and form closer to the galactic center than the ones that do not. Most clumps that reach high-$α$ merge with others and eventually spiral into the galactic center, but shed stars along the way to form most of the thick disk component.

description: We investigate the perturbative expansion in $SU(3)$ Yang-Mills theory compactified on $\mathbb{R}^2\times \mathbb{T}^2$ where the compact space is a torus $\mathbb{T}^2= S^1_β\times S^1_{L}$, with $S^1_β$ being a thermal circle with period $β=1/T$ ($T$ is the temperature) while $S^1_L$ is a circle with finite length $L=1/M$, where $M$ is an energy scale. A Linde-type analysis indicates that perturbative calculations for the pressure in this theory break down already at order $\mathcal{O}(g^2)$ due to the presence of a non-perturbative scale $\sim g \sqrt{TM}$. We conjecture that a similar result should hold if the torus is replaced by any other compact surface of genus one.

Year: 2018

description: The purchase process for wine is complex, since it has many dimensions which can influence decision making. Out of these many dimensions marketing mix is an important factor. Conventionally marketing mix referred as the 4P's. For the purpose of this research, product has been seen from two dimensions which are quality and packaging. The research is quantitative in nature and a mixed (descriptive and explanatory) research design has used. Both primary and secondary data have been used to conduct the study. Primary data was collected through structured questioner using a combination of convenience and purposive sampling techniques. The analysis has done using the software, Statistical Packages for Social Science (SPSS). The main objective of the study is to determine the effect of marketing mix on consumers buying decision, in perspective of Awash winery. The marketing mix elements that are considered includes product packaging, product quality, price, promotion and place/accessibility; and these are independent variables; so that the study has conducted to reveal the relationship between these independent variables and the dependent variable, consumer buying decision. The summary made based on the findings of the study with the objectives of determining the effect of marketing mix factors on wine consumers buying decision, implies that the factors namely, product packaging, product quality, price, promotion, and place have a great influence on consumers buying decision in purchasing wine products. By the same token the regression analysis shows that there is a positive and significant relationship between marketing mix and consumer buying decision

description: Crystal phase semiconductor heterostructures allow for electron confinement without uncertainties caused by chemical intermixing found in material heterostructures and are candidates for next generation optoelectronics devices ranging from single-photon emitters to high efficiency LEDs. While there has been a great deal of experimental work developing fabrication processes for these structures, theoretical calculations have been limited due to a lack of atomistic models that are able to incorporate the zincblende and wurtzite within the same structure. Here, we present calculations of the electronic energies in GaAs nanowires containing various thicknesses of zincblende and wurtzite layers using a recently developed tight-binding model for wurtzite III-V semiconductors that is compatible with a zincblende model. By comparing results in the flat-band and the unscreened limits, we explain the sensitivity of experimentally observed band gaps on zincblende and wurtzite well widths. Our calculations suggest that experiments on devices are likely near the flat-band limit under typical operating conditions.

Real-time donation efficiency

description: The study's primary objective is to present a fresh perspective on a donation platform that takes advantage of Bitcoin and the Lightning network, Layer 2, to provide real-time transparency on how donation funds are utilized by non-profit organizations. Current donation platforms frequently fail to provide live transparency metrics to donors, leaving them unsure of whether their contributions are properly utilized or not. The goal is to establish a fully transparent and traceable charitable giving platform with live efficiency metrics as well as implement a proof-of-concept to demonstrate the feasibility of such platform. Through monitoring the real-time movement of donations from the payment origin to the ultimate acquisition of the goods or services funded by the donations, the platform will enable donors to observe precisely how their contributions are being utilized. The decentralized and unchangeable characteristics of block-chain technology ensure the safe and transparent handling of donations while also instilling a sense of trust and responsibility in the donation process. The proposed donation platform would make it mandatory for all money used by non-profit organizations to have a valid invoice message outlining their intended purpose and identifying the expenditure category as either program, administrative, fundraising, or capital costs. The expenditure details will help donors visualize the real-time efficiency score, which is the percentage of funds spent on program expenses compared to the overall overhead incurred by the non-profit organization.

description: Supernova (SN) neutrinos can excite the nuclei of various detector materials beyond their neutron emission thresholds through charged current (CC) and neutral current (NC) interactions. The emitted neutrons, if detected, can be a signal for the supernova event. Here we present the results of our study of SN neutrino detection through the neutron channel in lead ($^{208} {\rm Pb}$) and iron ($^{56} {\rm Fe}$) detectors for realistic neutrino fluxes and energies given by the recent Basel/Darmstadt simulations for a 18 solar mass progenitor SN at a distance of 10 kpc. We find that, in general, the number of neutrons emitted per kTon of detector material for the neutrino luminosities and average energies of the different neutrino species as given by the Basel/Darmstadt simulations are significantly lower than those estimated in previous studies based on the results of earlier SN simulations. At the same time, we highlight the fact that, although the total number of neutrons produced per kTon in a iron detector is more than an order of magnitude lower than that for lead, the dominance of the flavor blind NC events in the case of iron, as opposed to dominance of $ν_e$ induced CC events in the case of lead, offers a complementarity between the two detector materials so that simultaneous detection of SN neutrinos in a lead and a sufficiently large iron detector suitably instrumented for neutron detection may allow estimating the fraction of the total $μ$ and $τ$ flavored neutrinos in the SN neutrino flux and thereby probing the emission mechanism as well as flavor oscillation scenarios of the SN neutrinos.

description: We consider a gravitational theory with two Maxwell fields, a dilatonic scalar and spatially dependent axions. Black brane solutions to this theory are Lifshitz-like and violate hyperscaling. Working with electrically charged solutions, we calculate analytically the holographic DC conductivities when both gauge fields are allowed to fluctuate. We discuss some of the subtleties associated with relating the horizon to the boundary data, focusing on the role of Lifshitz asymptotics and the presence of multiple gauge fields. The axionic scalars lead to momentum dissipation in the dual holographic theory. Finally, we examine the behavior of the DC conductivities as a function of temperature, and comment on the cases in which one can obtain a linear resistivity.

description: The wind farms in Texas southwest of Abilene are some of the oldest in the United States and have provided many researchers the opportunity to study the long-term effects of wind turbines on the environment. The principal objective of this thesis was to compare 2020 maximum and minimum land surface temperatures on both high- and low-generation days within and adjacent to an Abilene wind farm. This work shows the impact of turbine placement on differential temperature ranges and on diurnal temperatures and temperature ranges between and within high- and low-power generation days. I used National Aeronautics and Space Administration (NASA) 1-kilometer temperature data and QGIS for temperature differential, defined as the temperature difference at a specific location within a specific area compared to the same average difference for a control area outside of turbine influence. I compared temperature differentials within 1 km of wind turbines to those at 5 km or greater from the nearest turbine to define areas inside versus outside of turbine influence. First, the LST datasets show a statistically significant lower average temperature within wind farms compared to the average outside the farms for the high-generation day. Second, the LST datasets show a small but statistically significant higher average temperature within wind farms for low-generation day minimum temperatures. Third, there is no statistically significant average temperature difference between wind farms and areas outside of them when considering low-generation day maximum temperatures. The between generation days analysis reveals that the average difference in temperatures between high- and low-generation days within the wind farms was less than this same average difference outside of the wind farms. The high-generation day was associated with a slightly greater average range of diurnal temperature within wind farms compared to the average diurnal temperature range outside of the wind farms. The same isn’t true for the low-generation day, where there was no statistically significant difference in average diurnal temperature range. The Horse Hollow wind farm and adjacent turbines on high power generation days are associated with a noticeable land surface temperature decrease within the wind farm compared to the surrounding area.

Survival models with gene groups as covariates

subject: Humangenetik ; Genomik; Brustkrebs; Biostatistik

description: An important application of high-dimensional gene expression measurements is the risk prediction and the interpretation of the variables in the resulting survival models. A major problem in this context is the typically large number of genes compared to the number of observations (individuals). Feature selection procedures can generate predictive models with high prediction accuracy and at the same time low model complexity. However, interpretability of the resulting models is still limited due to little knowledge on many of the remaining selected genes. Thus, we summarize genes as gene groups defined by the hierarchically structured Gene Ontology (GO) and include these gene groups as covariates in the hazard regression models. Since expression profiles within GO groups are often heterogeneous, we present a new method to obtain subgroups with coherent patterns. We apply preclustering to genes within GO groups according to the correlation of their gene expression measurements. We compare Cox models for modeling disease free survival times of breast cancer patients. Besides classical clinical covariates we consider genes, GO groups and preclustered GO groups as additional genomic covariates. Survival models with preclustered gene groups as covariates have improved prediction accuracy in long term survival compared to models built only with single genes or GO groups. We also provide an analysis of frequently chosen covariates and comparisons to models using only clinical information. The preclustering information enables a more detailed analysis of the biological meaning of covariates selected in the final models. Compared to models built only with single genes there is additional functional information contained in the GO annotation, and compared to models using GO groups as covariates the preclustering yields coherent representative gene expression profiles. For evaluation of fitted survival models, we present prediction error curves revealing that models with preclustered gene groups have improved prediction performance compared to models built with single genes or GO groups.

description: The separation of quark and gluon initiated jets can be an important way to improve the sensitivity in searches for new physics or in measurements of Higgs boson properties. We present a simplified version of the shower deconstruction approach as a novel observable for quark-gluon tagging. Assuming topocluster-like objects as input, we compare our observable with energy correlation functions and find a favorable performance for a large variety of jet definitions. When applied to dark matter searches in mono-jet final states limitations from small signal-to-background ratios can be overcome. We also show that quark-gluon tagging is an alternative way of separating weak boson from gluon-fusion production in the process p + p -> H + jet + jet + X

description: While community health workers (CHWs) are a core feature of many low-resource healthcare systems, evidence on both their health impacts and the mechanisms behind these impacts remains limited. Using a difference-in-differences design with a control and treatment group, this study evaluated a CHW programme in southwestern Uganda aimed at improving maternal health outcomes. We found relatively little evidence of an overall programme effect on health behaviours, including antenatal care attendance and delivery under skilled supervision. Analysis of heterogeneity by gestational age at first antenatal visit—which should have modulated exposure to the intervention—provided suggestive evidence that treatment effects varied predictably with gestational age. Altogether, the absence of strong programme effects may have been due to suboptimal performance by CHWs, thus highlighting the importance of studying and instituting appropriate monitoring and incentive schemes for such programmes. Additionally, in contrast to the weak treatment effect findings, analysis of the entire study sample between the pre- and post-intervention periods showed large improvements in healthcare-seeking behaviour across both the treatment and control groups. These changes may have arisen from concurrent supply-side health facility improvements affecting the entire study population, spillover effects from the CHWs, or background health trends.

description: We developed a technique to determine suitable spin models for small embedded clusters of arbitrary geometry by combining the spin-cluster expansion with the relativistic disordered local moment scheme. We present results for uncovered and covered hexagonal Co clusters on Au(111) surface, and use classical Monte Carlo simulations to study the temperature dependent properties of the systems. To test the new method we compare the calculated spin-model parameters of the uncovered clusters with those of a Co monolayer deposited on Au(111). In general, the isotropic and DM interactions are larger between atoms at the perimeter than at the center of the clusters. For Co clusters covered by Au, both the contribution to the magnetic anisotropy and the easy axis direction of the perimeter atoms differ from those of the inner atoms due to reduced symmetry. We investigate the spin reversals of the covered clusters with perpendicular magnetic anisotropy and by measuring the magnetization variance in the easy direction we suggest a technique to determine the blocking temperature of superparamagnetic particles. We also determine the Néel relaxation time from the Monte Carlo simulations and find that it satisfies the Néel--Arrhenius law with an energy barrier close to the magnetic anisotropy energy of the clusters.

description: We present the first results of a 21 cm HI line pilot observation carried out with MeerKAT in preparation for the ViCTORIA project, an untargeted survey of the Virgo galaxy cluster. The extraordinary quality of the data in terms of sensitivity and angular resolution (rms~0.65 mJy beam^-1 at ~27"x39" and 11 km/s resolution) allowed us to detect an extended (~10 kpc projected length) low column density (N(HI) < 2.5x10^20 cm^-2) HI gas tail associated with the dwarf irregular galaxy NGC4523 at the northern edge of the cluster. The morphology of the tail and of the stellar disc suggest that the galaxy is suffering a hydrodynamic interaction with the surrounding hot intracluster medium (ICM; ram pressure stripping). The orientation of the trailing tail, the gradient in the HI gas column density at the interface between the cold ISM and the hot ICM, the velocity of the galaxy with respect to that of the cluster, and its position indicate that NGC4523 is infalling for the first time into Virgo from the NNW background of the cluster. Using a grid of hydrodynamic simulations we derive the impact parameters with the surrounding ICM, and estimate that the galaxy will be at pericentre (D~500-600 kpc) in ~1 Gyr, where ram pressure stripping will be able to remove most, if not all, of its gas. The galaxy is located on the star formation main sequence when its star formation rate is derived using Halpha images obtained during the VESTIGE survey, suggesting that NGC4523 is only at the beginning of its interaction with the surrounding environment. A few HII regions are detected in the Halpha images within the HI gas tail outside the stellar disc. Their ages, derived by comparing their Halpha, FUV, NUV, and optical colours with the predictions of SED fitting models, are <30 Myr, and suggest that these HII regions have formed within the stripped gas.

description: In the centre of pre-stellar cores, deuterium fractionation is enhanced due to the low temperatures and high densities. Therefore, the chemistry of deuterated molecules can be used to study the earliest stages of star formation. We analyse the deuterium fractionation of simple molecules, comparing the level of deuteration in the envelopes of the pre-stellar core L1544 in Taurus and the protostellar core HH211 in Perseus. We used single-dish observations of CCH, HCN, HNC, HCO$^+$, and their $^{13}$C-, $^{18}$O- and D-bearing isotopologues, detected with the Onsala 20m telescope. We derived the column densities and the deuterium fractions of the molecules. Additionally, we used radiative transfer simulations and results from chemical modelling to reproduce the observed molecular lines. We used new collisional rate coefficients for HNC, HN$^{13}$C, DNC, and DCN that consider the hyperfine structure of these molecules. We find high levels of deuteration for CCH (10%) in both sources, consistent with other carbon chains, and moderate levels for HCN (5-7%) and HNC (8%). The deuterium fraction of HCO$^+$ is enhanced towards HH211, most likely caused by isotope-selective photodissociation of C$^{18}$O. Similar levels of deuteration show that the process is likely equally efficient towards both cores, suggesting that the protostellar envelope still retains the chemical composition of the original pre-stellar core. The fact that the two cores are embedded in different molecular clouds also suggests that environmental conditions do not have a significant effect on the deuteration within dense cores. Radiative transfer modelling shows that it is necessary to include the outer layers of the cores to consider the effects of extended structures. Besides HCO$^+$ observations, HCN observations towards L1544 also require the presence of an outer diffuse layer where the molecules are relatively abundant.

description: In this study, we comprehensively investigate the production of isovector scalar meson $a_{0}(1817)$ using the effective Lagrangian approach. Specifically, we employ the Reggeized $t$ channel Born term to calculate the total and differential cross sections for the reaction $K^{-}p \rightarrow a_{0}(1817)Λ$. Our analysis reveals that the optimal energy range for detecting the $a_{0}(1817)$ meson lies between $W=3.4$ GeV and $W=3.6$ GeV, where the predicted total cross section reaches a minimum value of 112 nb. Notably, the $t$ channel, as predicted by the Regge model, significantly enhances the differential cross sections, particularly at extreme forward angles. Furthermore, we investigate the Dalitz processes of $2\rightarrow 3$ and discuss the feasibility of detecting the $a_{0}(1817)$ meson in experiments such as J-PARC.

description: The research entitled, The Role of Brand Equity on Customers Bank Choice. (A Case Study on Enat Bank Sc.). This research tries to answer to basic research questions: How brand equity affects customer's bank choice? and Which brand equity dimension has more effect on customers' bank choice?. The purpose with this research is that to light on the extent of customer based brand equity in banking industry and to find out how customers perceive the value and brand of the bank they are using for the financial services of their business and personal wish for. To fill full the above aim the research used a quantitative method and a deductive approach for this thesis. Hypotheses were created with theory as a base and tested on a sample population of Enat Bank selected branches customers in Addis Ababa. The data were compared with mean, standard deviation and variance using SPSS. Cronbach's alpha, Pearson's correlation, and Regression analysis were used to improve reliability and test the correlation between statements used in the study. The theory is based on Aaker (1991) and Keller (1993) and their research and theories about branding, surrounded by findings done by other researchers within the subject. The most significant finding in this study was that the most important factors for customers bank choice are related to brand associations, brand activity and brand loyalty towards the brand equity of the bank. Having positive feelings about the bank, the service from employees and their ability, the satisfaction from the financial services of the bank, and the uniqueness of the bank are the most important part according to the findings in this research.

description: We show that under an a.c. magnetic field excitation the vortex lattice in a superconductor with periodic array of holes can undergo a transition from a Mott-like state where each vortex is localized in a hole, to a metal-like state where the vortices get delocalized. The vortex dynamics is studied through the magnetic shielding response which is measured using a low frequency two-coil mutual inductance technique on a disordered superconducting NbN film having periodic array of holes. We observe that the shielding response of the vortex state is strongly dependent on the amplitude of the a.c. magnetic excitation. At low amplitude the shielding response varies smoothly with excitation amplitude, corresponding to elastic deformation of the vortex lattice. However, above a threshold value of excitation the response shows a series of sharp jumps, signaling the onset of the Mott to metal transition. Quantitative analysis reveals that this is a collective phenomenon which depends on the filling fraction of vortices in the antidot lattice.

description: Rebreathing-induced hypoxia elicits changes in pulmonary gas exchange variables. PURPOSE: This report aims to determine the changes in pulmonary gas exchange variables in response to a rebreathing-induced hypoxia protocol in individuals who are healthy, have prediabetes, or have type 2 diabetes. METHODS: Fifteen participants (M: 9, age 45 ± 17 years, body mass index: 34.2 ± 8.0 kg/m²) visited the laboratory. A 2-hour, 75 g oral glucose tolerance test was conducted during the study visit while simultaneously performing a rebreathing-induced hypoxia protocol. Venous blood samples were collected 0, 30-, 60-, 90-, and 120-min following ingestion of the glucose drink to measure plasma glucose and insulin levels. The rebreathing-induced hypoxia protocol consisted of two series of five 2-min rebreathing bouts in a low-volume, closed circuit system interspersed with two minutes of breathing room air. The first and second series of rebreathing bouts were performed within the first 30 min and 30-60 min after ingesting the glucose drink, respectively. Pulmonary gas exchange was measured using a metabolic cart. RESULTS: End-tidal oxygen, fraction of inspired oxygen, and respiratory rate decreased during rebreathing-induced hypoxia. Tidal volume, minute ventilation, oxygen uptake, and end-tidal carbon dioxide increased during rebreathing-induced hypoxia. CONCLUSION: Rebreathing-induced hypoxia elicits changes in pulmonary gas exchange in individuals who are healthy, have prediabetes, or have type 2 diabetes.
