description: Developing systematic conservation plans depends on a wealth of information on a region's biodiversity. For 'dark taxa' such as arthropods, such data is usually very incomplete and in most cases left out from assessments. Sky islands are important and often fragile biodiversity hotspots. Southern Appalachian high-elevation spruce-fir forests represent a particularly threatened sky-island ecosystem, hosting numerous endemic and threatened species, but their arthropods remain understudied. Here we use voucher-based megabarcoding to explore genetic differentiation among leaf-litter arthropod communities of these highlands, and to examine the extent to which they represent dispersed communities of more or less coherent species, manageable as a distributed unit. We assembled a dataset comprising >6000 COI sequences representing diverse arthropod groups to assess species richness and sharing across peaks and ranges. Comparisons were standardized across taxa using automated species delimitation, measuring endemism levels by putative species. Species-richness was high, with sites hosting from 86-199 litter arthropod species (not including mites or myriapods). Community profiles suggest that around one-fourth of these species are unique to single sky islands and more than one-third of all species are limited to a particular range. Across major taxa, endemicity was lowest in Araneae, and highest in neglected groups like Isopoda, Pseudoscorpionida, Protura, and Diplura. Southern Appalachian sky islands of spruce-fir habitat host significantly distinct leaf litter arthropod communities, with high levels of local endemicity. This is the first work to provide such a clear picture of peak and range uniqueness for a taxonomically broad sample. Ensuring the protection of a sizeable fraction of high-elevation litter species richness will therefore require attention at a relatively fine spatial scale.

description: Background: Inequalities by race and ethnicity in hysterectomy for noncancerous conditions suggest that some subgroups may be shouldering an unfair burden of procedure-associated negative health impacts. We aimed to estimate race- A nd ethnicity-specific rates in contemporary hysterectomy incidence that address three challenges in the literature: Exclusion of outpatient procedures, no hysterectomy prevalence adjustment, and paucity of non-White and non-Black estimates. Methods: We used surveillance data capturing all inpatient and outpatient hysterectomy procedures performed in North Carolina from 2011 to 2014 (N = 30,429). Integrating data from the Behavior Risk Factor Surveillance System and US Census population estimates, we calculated prevalence-corrected hysterectomy incidence rates and differences by race and ethnicity. Results: Prevalence-corrected estimates show that non-Hispanic (nH) Blacks (62, 95% confidence interval [CI] = 61, 63) and nH American Indians (85, 95% CI = 79, 93) per 10,000 person-years (PY) had higher rates, compared with nH Whites (45 [95% CI = 45, 46] per 10,000 PY), while Hispanic (20, 95% CI = 20, 21) and nH Asian/Pacific Islander rates (8, 95% CI = 8.0, 8.2) per 10,000 PY were lower than nH Whites. Conclusion: Through strategic surveillance data use and application of bias correction methods, we demonstrate wide differences in hysterectomy incidence by race and ethnicity.

description: We have developed and optimized two categories of spin transfer torque magnetic tunnel junctions (STT-MTJs) that exhibit a high tunnel magnetoresistance (TMR) ratio, low critical current, high outputpower in the micro watt range, and auto-oscillation behavior. These characteristics demonstrate the potential of STT-MTJs for low-power, high-speed, and reliable spintronic applications, including magnetic memory, logic, and signal processing. The only distinguishing factor between the two categories, denoted as A-MTJs and B-MTJs, is the composition of their free layers, 2 CoFeB/0.21 Ta/6 CoFeSiB for A-MTJs and 2 CoFeB/0.21 Ta/7 NiFe for B-MTJs. Our study reveals that B-MTJs exhibit lower critical currents for auto-oscillation than A-MTJs. We found that both stacks have comparable saturation magnetization and anisotropy field, suggesting that the difference in auto-oscillation behavior is due to the higher damping of A-MTJs compared to B-MTJs. To verify this hypothesis, we employed the all-optical time-resolved magneto-optical Kerr effect (TRMOKE) technique, which confirmed that STT-MTJs with lower damping exhibited auto-oscillation at lower critical current values. Additionally, our study aimed to optimize the STT-MTJ performance by investigating the impact of the capping layer on the device's response to electronic and optical stimuli.

description: Στην παρούσα μελέτη καταγράφηκε η δημιουργία νέων συστημάτων χορήγησης φαρμάκων από το στόμα. Το πρώτο σύστημα ήταν οι ελαιοπηκτές οι οποίες αποτελούνται από λιπαρά οξέα και κηρούς σε διαφορετικές περιεκτικότητες. Τα έλαια που χρησιμοποιήθηκαν ήταν σογιέλαιο, λινέλαιο, σταφυλέλαιο, καρθαμέλαιο, λάδι καρύδας και ελαιόλαδο, ενώ χρησιμοποιήθηκαν παράλληλα κηροί μέλισσας, καντελίλα και καρναούμπα. Τα αποτελέσματα εξήχθησαν μέσω FTIR. Οι οργανοπηκτές που μελετήθηκαν έχουν ως βάση το μονογλυκερίδιο και δοκιμάστηκαν με tween-60 και γλυκερίνη σε διαφορετικές περιεκτικότητες. Η χρωστική ροδαμίνη-Β, που θεωρείται model drug, χρησιμοποιήθηκε στις οργανοπηκτές και αναμείχθηκαν με υγρά προσομοίωσης (SIF, SGF, SS, PBS). Τα αποτελέσματα εξήχθησαν μέσω φασματοφωτομέτρου. Σαν αποτέλεσμα των πειραμάτων εξήχθη ότι είναι εφικτός ο σχηματισμός σταθερών συστημάτων per os χορήγησης και συγκεκριμένα με ενσωμάτωση δραστικής ουσίας που προσομοιάζει στη ροδαμίνη-Β
description: In the present study, the development of new per os drug delivery systems were recorded. The first system was the oleogels where apart from L.O. and waxes in different contents were added. The oils used were soybean oil, flaxseed oil, grapeseed oil, sufflower oil, coconut oil, olive oil and the waxes were bee, candelilla, carnauba as well. The results were exported via FTIR. The organogels studied were based on mono-glyceride and tested with tween-60 and glycerol in different contents. In the organogels, no active substance was used except the dye rhodamine-B which is considered a model drug and tested in simulation fluids (SIF, SGF, SBF, PBS). The results were extracted by fluoroscence spectroscopy. From the above experiments emerged that it is possible to form stable systems per os administration and by incorporating an active substance that resembles rhodamine-Β

description: The Medium-Resolution Spectrometer (MRS) provides one of the four operating modes of the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST). The MRS is an integral field spectrometer, measuring the spatial and spectral distributions of light across the 5-28 $μm$ wavelength range with a spectral resolving power between 3700-1300. We present the MRS's optical, spectral, and spectro-photometric performance, as achieved in flight, and we report on the effects that limit the instrument's ultimate sensitivity. The MRS flight performance has been quantified using observations of stars, planetary nebulae, and planets in our Solar System. The precision and accuracy of this calibration was checked against celestial calibrators with well-known flux levels and spectral features. We find that the MRS geometric calibration has a distortion solution accuracy relative to the commanded position of 8 mas at 5 $μm$ and 23 mas at 28 $μm$. The wavelength calibration is accurate to within 9 km/sec at 5 $μm$ and 27 km/sec at 28 $μm$. The uncertainty in the absolute spectro-photometric calibration accuracy was estimated at 5.6 +- 0.7 %. The MIRI calibration pipeline is able to suppress the amplitude of spectral fringes to below 1.5 % for both extended and point sources across the entire wavelength range. The MRS point spread function (PSF) is 60 % broader than the diffraction limit along its long axis at 5 $μm$ and is 15 % broader at 28 $μm$. The MRS flight performance is found to be better than prelaunch expectations. The MRS is one of the most subscribed observing modes of JWST and is yielding many high-profile publications. It is currently humanity's most powerful instrument for measuring the mid-infrared spectra of celestial sources and is expected to continue as such for many years to come.

description: Introduction: Acute diarrheal diseases are the leading cause of preventable death, especially among children under-five in developing countries. Worldwide and nationwide (Ethiopia) diarrheal disease is the second leading cause of death in under-five year children only to pneumonia. Objectives: The aim of this study was to determine the magnitude and associated factors of under-five diarrhea in Laelay-Maychew district. Methods: A community based Cross sectional study was conducted from February 01- February 15, 2015. A two stage stratified sampling method was done to select the eligible households. Data was collected by trained data collectors using standard questionnaire and observational check list tested previously which was prepared based on EDHS and WHO core questionnaires related to diarrhea. Data was entered in to a computer using Epi Info 3.5.3 software and exported to SPSS V.21 statistical software for further analysis. Binary Logistic regression analysis was used to determine OR and 95% CI. Variables with p-value <0.2 in the bivariate analysis were entered in to multivariate analysis and with p-value <0.05 in the final model were considered as significant. Result: The two weeks period magnitude of diarrhea among under-five children was 17.7% with 95% CI (14.5-20.8) which was associated with children being rural residence [AOR: 1.52, 95% CI(1.26,4.87)], female child [AOR: 3.85, 95% CI(1.8,8.22)], education of mothers [AOR: 0.02, 95% CI(0.01,0.12)], households with improved water source [AOR: 0.18, 95% CI(0.02,0.39)], households with ≤20L per capita per day water consumption [AOR: 1.53, 95% CI(1.12,1.97)], and mothers who wash their hand with water and soap/ash [AOR: 0.52, 95% CI(0.24,0.42)]. Conclusion and recommendation: The two weeks period magnitude of acute under-five diarrhea was relatively high and residence, educational status of the mothers, water source of the households, per capita water consumption of the households, and hand washing methods of the mothers/care takers were significant predictors. So, Females' education at least to complete primary school, constructing improved water source and giving HE to the community about hand washing methods to use soap at recommended times were recommended

description: We demonstrate a high-power narrow-linewidth ultraviolet (UV) laser system at 318.6 nm for direct 6S1/2-nP (n = 70 to 100) Rydberg excitation of cesium atoms. Based on commercial fiber lasers and efficient nonlinear frequency conversion technology, 2.26 W of tunable UV laser power is obtained from cavity-enhanced second harmonic generation following sum-frequency generation of two infrared lasers at 1560.5 nm and 1076.9 nm to 637.2 nm. The maximum doubling efficiency is 57.3%. The typical UV laser power root-mean-square fluctuation is less than 0.87% over 30 minutes, and the continuously tunable range of the UV laser frequency is more than 6 GHz. Its beam quality factors M2 X and M2 Y are 1.16 and 1.48, respectively. This high-performance UV laser has significant potential use in quantum optics and cold atom physics.

description: The scope of the thesis is to predict employee attrition, an information that will be utilized mainly by the Human Resources departments. The general objective of the study is to create predictive models that will foretell the possibility of an employee’s resignation and assay which one provides the highest accuracy. Overall, the current thesis presents the machine learning algorithms that were implemented, techniques for finding which features are the best predictors, and assessment of the results by existing HR departments. The research questions of this thesis are the following: Which algorithm provides the most accurate results for predicting employee attrition? What are the attributes that are considered best predictors? How this knowledge is of importance to the HR departments? First, we implemented three different algorithms, Naive Bayes, Support Vector Machines and Random Forest to compare the corresponding accuracy of each of them.Then, we applied some feature selection techniques and a method of feature extraction to assess which are the features with the major importance to the prediction model. Finally, we shared our findings with some HR departments to provide their own feedback and evaluate the results

description: We present photometric and spectroscopic observations and analysis of SN 2021bxu (ATLAS21dov), a low-luminosity, fast-evolving Type IIb supernova (SN). SN 2021bxu is unique, showing a large initial decline in brightness followed by a short plateau phase. With $M_r = -15.93 \pm 0.16\, \mathrm{mag}$ during the plateau, it is at the lower end of the luminosity distribution of stripped-envelope supernovae (SE-SNe) and shows a distinct $\sim$10 day plateau not caused by H- or He-recombination. SN 2021bxu shows line velocities which are at least $\sim1500\,\mathrm{km\,s^{-1}}$ slower than typical SE-SNe. It is photometrically and spectroscopically similar to Type IIb SNe during the photospheric phases of evolution, with similarities to Ca-rich IIb SNe. We find that the bolometric light curve is best described by a composite model of shock interaction between the ejecta and an envelope of extended material, combined with a typical SN IIb powered by the radioactive decay of $^{56}$Ni. The best-fit parameters for SN 2021bxu include a $^{56}$Ni mass of $M_{\mathrm{Ni}} = 0.029^{+0.004}_{-0.005}\,\mathrm{M_{\odot}}$, an ejecta mass of $M_{\mathrm{ej}} = 0.61^{+0.06}_{-0.05}\,\mathrm{M_{\odot}}$, and an ejecta kinetic energy of $K_{\mathrm{ej}} = 8.8^{+1.1}_{-1.0} \times 10^{49}\, \mathrm{erg}$. From the fits to the properties of the extended material of Ca-rich IIb SNe we find a trend of decreasing envelope radius with increasing envelope mass. SN 2021bxu has $M_{\mathrm{Ni}}$ on the low end compared to SE-SNe and Ca-rich SNe in the literature, demonstrating that SN 2021bxu-like events are rare explosions in extreme areas of parameter space. The progenitor of SN 2021bxu is likely a low mass He star with an extended envelope.

description: The aim of this study was to evaluate the effect of acute and chronic physical and psychological stressors on the induction of oxidative stress in male rat liver. Male Wistar rats were randomly divided into 3 groups as following: control, physical and psychological stress groups. Stress was induced by communication box for one (acute), fifteen and thirty (chronic) days. Once stressor periods ended, rats were anesthetized and their liver dissected out for later assessments. Exposure to physical stress enhanced liver superoxide dismutase (SOD) (19.44 %) and glutathione S-transferase (GST) (21.84 %) activities and decreased glutathione (GSH) (30.03 %) level on the 1st day (p<0.05). SOD (24.13 and 18.43 %) and GST (27.77 and 21.27 %) activities were significantly increased, while catalase activity (29.74 and 24.41 %) and GSH level (35.05 and 31.05 %) were decreased in psychological stress group after 1 and 15 days (p<0.01 and p<0.05) compared to the 1st day value in control group, respectively. Psychological stress induced an increase in liver malondialdehyde (MDA) (46 %) and plasma corticosterone (36 %) levels on the 1st day (p<0.05). However, all parameters returned to their basal value after 30 days of stress. The results suggest that exposure to acute physical and psychological stressors induce the production of reactive oxygen species and oxidative stress in rat liver due to GSH depletion and the decreased catalase activity. The elevation of lipid peroxidation and corticosterone level in acute psychological stress may lead to more profound oxidative damage than acute physical stress. Moreover, cell protection in hepatic tissue of chronically stressed rats is indicative of possible late adaptation of the animals to stress.

description: A two-loop induced radiative neutrino model is proposed as an extension of our previous work in which the first and second generation standard model fermion masses are generated at one-loop level in both quark and lepton sectors. Then we discuss current neutrino oscillation data, lepton flavor violations, muon anomalous magnetic moment, and a bosonic dark matter candidate, for both the normal and inverted neutrino mass hierarchy. Our numerical analysis shows that less hierarchical Yukawa coupling constants can fit the experimental data with TeV scale dark matter.

Validating PM2.5 Concentrations measured by PATS+Relative to UPAS device in households in Addis Abeba.
Creators: name: Ayalew, Mulugeta
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background; - PM2.5 is an indicator of household air pollutants to measure the risk of air pollution. UPAS and PATS+ PM measuring instruments are portable monitors that were used to measure particulate matters in the households of Addis Ababa in a GEO Health for Eastern Africa. The validity of the measurements using these two instruments is a concern for exposure assessment as they use different principles of measuring PM2.5. Objective: This study aims to validating PM2.5 concentrations measured by PATS+ relative to UPAS device in households in Addis Ababa and explore factors affecting the level of UPAS PM2.5 concentration. Methods: The study was cross-sectional, involving 150 households. The study used two instruments with different technologies: the light scattering method in PATS+ and the gravimetric in UPAS. Fifteen households were randomly selected from each sub-city from the source population that it used GEO Health project for Children's Health Study. Different statistical tools were used to explore the consistency and validity of the measured PM2.5 by the two tools used to monitor for 24 hours for each household: paired t-test, and Bland-Altman scatter plot analysis were performed to evaluate the extent of agreement. P-Value <0.05 and 95% CI of parameters were used for statistical significance. Results: There wasno agreement and had a proportional bias between PATS+ and UPAS measured PM2.5 concentrations. Child room located in the kitchen and household had highpollution levelwere affected UPAS PM2.5concentration. We recommend the need of a correction factor for PM2.5concentration measured by PATS+. Conclusion and Recommendations There is difference in PATS+ and UPAS measured PM2.5 concentration and has no agreement. The location of child room and the pollution category of the household had an effect on the measurments of PM2.5concentration. Generating a correction factor for PATS+ monitor using UPAS as a gold standard is suggested.

description: Merging galaxy clusters have been touted as one of the best probes for constraining self-interacting dark matter, but few simulations exist to back up this claim. We simulate equal mass mergers of 10$^{15}$ M$_\odot$ halos, like the El Gordo and Sausage clusters, with cosmologically-motivated halo and merger parameters, and with velocity-independent dark-matter self-interactions. Although the standard lore for merging clusters is that self-interactions lead to large separations between the galaxy and dark-matter distributions, we find that maximal galaxy-dark matter offsets of $\lesssim~20$~kpc form for a self-interaction cross section of $σ_\text{SI}/m_χ$ = 1 cm$^2$/g. This is an order of magnitude smaller than those measured in observed equal mass and near equal mass mergers, and is likely to be even smaller for lower-mass systems. While competitive cross-section constraints are thus unlikely to emerge from offsets, we find other signatures of self-interactions which are more promising. Intriguingly, we find that after dark matter halos coalesce, the collisionless galaxies (and especially the Brightest Cluster Galaxy [BGC]) oscillate around the center of the merger remnant on stable orbits of 100 kpc for $σ_\text{SI}/m_χ= 1$~cm$^2$/g for at least several Gyr, well after the clusters have relaxed. If BCG miscentering in relaxed clusters remains a robust prediction of SIDM under the addition of gas physics, substructure, merger mass ratios (e.g., 10:1 like the Bullet Cluster), and complex cosmological merger histories, the observed BCG offsets may constrain $σ_\text{SI}/m_χ\lesssim$ 0.1 cm$^2$/g---the tightest constraint yet.

description: Feshbach association of ultracold molecules using narrow resonances requires exquisite control of the applied magnetic field. Here we present a magnetic field control system to deliver magnetic fields of over 1000 G with ppm-level precision integrated into an ultracold-atom experimental setup. We combine a battery-powered current-stabilized power supply with active feedback stabilization of the magnetic field using fluxgate magnetic field sensors. As a real-world test we perform microwave spectroscopy of ultracold Rb atoms and demonstrate an upper limit on our magnetic field stability of 2.4(3) mG at 1050 G [2.3(3) ppm relative] as determined from the spectral feature.

description: There is an increasing interest in nonlinear supersymmetries in cosmological model building. Independently, elegant expressions for the all-tree amplitudes in models with nonlinear symmetries, like D3 brane Dirac-Born-Infeld-Volkov-Akulov theory, were recently discovered. Using the generalized background field method we show how, in general, nonlinear symmetries of the action, bosonic and fermionic, constrain amplitudes beyond soft limits. The same identities control, for example, bosonic E_{7(7)} scalar sector symmetries as well as the fermionic goldstino symmetries. We present a universal derivation of the vanishing amplitudes in the single (bosonic or fermionic) soft limit. We explain why, universally, the double-soft limit probes the coset space algebra. We also provide identities describing the multiple-soft limit. We discuss loop corrections to N\geq 5 supergravity, to the D3 brane, and the UV completion of constrained multiplets in string theory.

description: High-index Bi2Se3(221) film has been grown on In2Se3-buffered GaAs(001), in which a much retarded strain relaxation dynamics is recorded. The slow strain-relaxation process of in epitaxial Bi2Se3(221) can be attributed to the layered structure of Bi2Se3 crystal, where the epifilm grown along [221] is like a pile of weakly-coupled quintuple layer slabs stacked side-by-side on substrate. Finally, we have revealed the strong chemical bonding at the interface of Bi2Se3 and In2Se3 by plotting differential charge contour calculated by first-principle method. This study points to the feasibility of achieving strained TIs for manipulating the properties of topological systems.

description: A large number of fast radio bursts (FRBs) detected with the CHIME telescope have enabled investigations of their energy distributions in different redshift intervals, incorporating the consideration of the selection effects of CHIME. As a result, we obtained a non-evolving energy function (EF) for the high-energy FRBs (HEFRBs) of energies $E\gtrsim2\times0^{38}$ erg, which takes the form of a power law with a low-energy exponential cutoff. On the contrary, the energy distribution of the low-energy FRBs (LEFRBs) obviously cannot be described by the same EF. Including the lowest dispersion measure (DM) samples, the LEFRBs are concentrated towards the Galactic plane and their latitude distribution is similar to that of Galactic rotational radio transients (RRATs). These indications hint that LEFRBs might compose a special type of RRATs, with relatively higher DMs and energies (i.e., $\sim10^{28-31}$ erg for a reference distance of $\sim10$ kpc if they belong to the Milky Way). Finally, we revisit the redshift-dependent event rate of HEFRBs and confirm that they could be produced by the remnants of cosmological compact binary mergers.

description: Purpose: Estimates of cancer therapy effects can differ in clinical trials and clinical practice, partly due to underrepresentation of certain patient subgroups in trials. We utilize a hybrid approach, combining clinical trial and real-world data, to estimate the comparative effectiveness of two adjuvant chemotherapy regimens for colon cancer. Methods: We identified patients aged 66 and older enrolled in the Multicenter International Study of Oxaliplatin/5FU-LV in the Adjuvant Treatment of Colon Cancer. Similar patients were identified in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database, initiating adjuvant chemotherapy with either 5-fluorouracil (5FU) alone or in combination with oxaliplatin (FOLFOX). We used logistic regression to estimate the likelihood of trial enrollment as a function of age, sex, and substage. Using inverse odds of sampling weights (IOSW), we compared 5-year mortality in patients randomized to FOLFOX vs 5FU using weighted Cox proportional hazards regression, the Nelson-Aalen estimator for cumulative hazards, and bootstrapping for 95% confidence intervals (CIs). Results: There were 690 trial participants and 3834 SEER-Medicare patients. The SEER-Medicare population was older and had a higher proportion of stage IIIB and IIIC patients than the trial. After controlling for differences between populations, the IOSW 5-year HR was 1.21 (0.89, 1.65), slightly farther from the null than the trial estimate (HR = 1.14, 95%CI: 0.87, 1.49). Conclusions: This study supports mounting evidence of little to no incremental reduction in 5-year mortality for FOLFOX vs 5FU in older adults with stage II-III colon cancer, emphasizing the importance of combining clinical trial and real-world data to support such conclusions.
TaO$^+$, a Candidate Molecular Ion in Search of Physics Beyond the Standard Model

description: The TaO$^+$ molecular ion is proposed as a candidate system for detecting signatures of charge parity (${\cal{CP}}$) violating physics beyond the standard model of elementary particles. The electron electric dipole moment (EDM) effective electric field $E_{\text{eff}} = 20.2 \left[\frac{\rm GV}{\rm cm}\right]$, the nucleon-electron scalar-pseudoscalar (ne-SPS) interaction constant $W_{S} = 17.7$ [kHz] and the nuclear magnetic quadrupole interaction constant $W_M = 0.45$ [$\frac{10^{33} {\text{Hz}}}{e\, {\text{cm}}^2}$] are found to be sizeable ${\cal{P,T}}$-odd enhancements. The ratio of the leptonic and semi-leptonic enhancements differs strongly from the one for the ThO system which may provide improved limits on the electron EDM, $d_e$, and the SPS coupling constant, $C_S$. TaO$^+$ is found to have a ${^3Δ_1}$ electronic ground state like the previously proposed ThF$^+$ molecular ion, but an order of magnitude smaller parallel G-tensor component which makes it less vulnerable to systematic errors in experiment.

Lived Experience of Substance abuse among addicted Youth in Mekelle City, Northernethiopia: APhenomenologic study.
Creators: name: Hailemariam, Ferehiwot
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: Substance abuse such as alcohol, tobacco and illicit drugs become a public health concern globally. Despite that substance abuse is associated with negative health, economic and social outcomes; there is a gap in understanding the reasons and extent of the problem at ground and realizing the lived experiences of substance addicted youths from their own perspectives. Therefore, this study was aimed to explore the lived experience of addicted youths on substance abuse in Mekelle city, Northern Ethiopia. Methods: Phenomenological qualitative study was conducted from March 20 up to April 30, 2019 among 15 substances addicted youths in Mekelle city. Youths between 15 -29 years old, who had been using alcohol, and/or tobacco, chat or any illicit substances and used to live in Mekelle city residency were purposively selected from a substance rehabilitation center. The investigator conducted the interviews using semi structured guide through in-depth interview technique. Data were audio recorded, transcribed verbatim and translated in to English and finally imported to atlas.ti.7.5 software for coding. Analysis was done inductively. Code book development, peer debriefing, multiple coders and member checking were applied to maintain rigor of the data. Results: the findings revealed that reasons related to socialization issues with peer pressure at the center, relief from stress and as energy booster were the main features in the process of youth's initiation for substance abuse. Moreover, youths lack of awareness on risks of the substances, ease access to substances in their neighborhood and being jobless conditions influenced them to abuse different substances on daily basis. As a result, the youths were exposed to various risky behaviors including violence and unsafe sexual practices. Conclusion: Different personal, interpersonal and environmental factors were explored in the initiation of youths for substance abuse. Youths experience various problems and their life was negatively affected as a result. Hence multiple interventions at individual, community and organizational levels are suggested to tackle the problem in the area.

description: The structural stabilities of the monoclinic and tetragonal phases of Si-doped HfO$_{2}$ at finite temperatures were analyzed using a computational scheme to assess the effects of impurity doping. The finite temperature effects considered in this work represented lattice vibration and impurity configuration effects. The results show that 6% Si doping stabilizes the tetragonal phase at room temperature, although a higher concentration of Si is required to stabilize the tetragonal phase at zero temperature. These data indicate that lattice vibration and impurity configuration effects are important factors determining structural stability at finite temperatures.

description: In this master thesis we examine the radiological impact of an accident in a hypothetical nuclear power plant in Greece. First we present information about the operation of an average nuclear power plant, regarding the design and fuel used. Then the geomorphological characteristics of Greece as well as the existing power grid are taken into consideration in order to propose a feasible location for the power plant. Meteorological data for the proposed locations are gathered in order to be used as inputs in the Hotspot program. Finally, the outputs of each case study of the Hotspot are represented in Google Earth, from where conclusions were drawn
