description: Recently an algorithm to dualize a theory into its mirror dual has been proposed, both for $3d$ $\mathcal{N}=4$ linear quivers and for their $4d$ $\mathcal{N}=1$ uplift. This mimics the manipulations done at the level of the Type IIB brane setup that engineers the $3d$ theories, where mirror symmetry is realized as $S$-duality, but it is enirely field-theoretic and based on the application of genuine infra-red dualities that implement the local action of $S$-duality on the quiver. In this paper, we generalize the algorithm to the full duality group, which is $SL(2,\mathbb{Z})$ in $3d$ and $PSL(2,\mathbb{Z})$ in $4d$. This also produces dualities for $3d$ $\mathcal{N}=3$ theories with Chern--Simons couplings, some of which have enhanced $\mathcal{N}=4$ supersymmetry, and their new $4d$ $\mathcal{N}=1$ counterpart. In addition, we propose three ways to study the RG flows triggered by possible VEVs appearing at the last step of the algorithm, one of which uses a new duality that implements the Hanany--Witten move in field theory.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1996

description: Internal migration is observed to cause major imbalances in the availability of economic and social opportunities due to fluctuation in composition and size of the population. A retrospective longitudinal study was conducted in Meskan and Mareko Woreda to describe the magnitude, patterns and differentials of internal migration in 9 PAs and 1 UDA sampled using probability proportionate to size. Data on variables of population mobility were collected by BRHP using monthly household visits for the period 1987-1994. In addition, in-depth interviews with key informants, focus group discussions & observation were conducted in the study sites. Results showed that during the 1987-1994 there was a total of 18,426 moves, of which 9,610 (52%) were in-migrants and 8,816 (48%) were out-migrants. The sex distribution of both in- and out-migrants demonstrate that females outnumber males. The age group with the highest percentage of internal migrants is in the range of 15-24 years. The observed rates per 1000 mid-year population are 36.0 and 33.1 for in- and out-migration respectively while the net-migration was 2.9 per 1000 mid-year population. It is observed that both in- and out-migrants are in the active and productive age group. The pattern of population movement is mainly seasonal. Employment & marriage appear to be the main motives for the population movement in the area while education is also becoming important. The pattern of age/sex selectivity of migration has important public health implications, in that they affect the relative size of important target group, such as children 0-4 & female 15-24 years. Further detailed studies to fully understand migration streams, determinants & consequences are essential

description: Single-dish sub-millimeter observations have recently revealed the existence of a substantial, chemically peculiar, molecular gas component located in the innermost circumstellar environment of the very massive luminous blue variable star $η$ Carinae. Here, we present 5$"$-resolution interferometric observations of the 1$\rightarrow$0 rotational transition of hydrogen cyanide (HCN) obtained with the Australia Telescope Compact Array (ATCA) toward this star. The emission is concentrated in the central few arcseconds around $η$ Carinae and shows a clear 150 km s$^{-1}$ velocity gradient running from west-north-west (blue) to east-south-east (red). Given the extent, location, and kinematics of this molecular material, we associate it with the complex of dusty arcs and knots seen in mid-infrared emission near the center of the Homunculus nebula. Indeed, the shielding provided by this dust could help explain how molecules survive in the presence of the intense UV radiation field produced by $η$ Carinae. The dust located in the central few arcseconds around $η$ Carinae and the molecular component described here have most likely formed in situ, out of material expelled by the massive interacting binary system. Thus, $η$ Carinae offers us a rare glimpse on the processes leading to the formation of dust and molecules around massive stars that are so relevant to the interpretation of dust and molecule detections at high redshifts.

description: We study a non-supersymmetric SO(10) Grand Unification Theory with a very high energy intermediate symmetry breaking scale in which not only gauge but also Yukawa coupling unification are enforced via suitable threshold corrections and matching conditions. For gauge unification, we focus on a few symmetry breaking patterns with the intermediate gauge groups ${\rm SU(4)_C \times SU(2)_L \times SU(2)_R}$ (Pati-Salam) and ${\rm SU(3)_C \times SU(2)_L \times SU(2)_R\times U(1)_{B-L}}$ (minimal left-right symmetry) assuming an additional global U(1) Peccei--Quinn symmetry, and having the Standard Model supplemented by a second Higgs doublet field at the electroweak scale. We derive the conditions as well as the approximate analytical solutions for the unification of the gauge coupling constants at the two-loop level and discuss the constraints from proton decay on the resulting high scale. Specializing to the case of the Pati-Salam intermediate breaking pattern, we then impose also the unification of the Yukawa couplings of third generation fermions at the high scale, again at the two-loop level. In the considered context, Yukawa unification implies a relation between the fermion couplings to the 10- and 126-dimensional scalar representations of the SO(10) group. We consider one such possible relation which is obtainable in an ${\rm E_6}$ model where the previous two scalar fields are part of a single multiplet. Taking into account some phenomenological features such as the absence of flavor changing neutral currents at tree-level, we derive constraints on the parameters of the low energy model, in particular on the ratio of the two Higgs doublets vacuum expectation values $\tanβ$.

description: Background: Low back pain is a common musculoskeletal disorder affecting about eighty percent of people at some point in their lives. Globally, 37% of low back pain was deemed attributable to occupational risk factors and the magnitude was generally higher in those regions with lower overall health status. Objective: To assess the magnitude and contributing factors of low back pain among long distance truck drivers at Modjo dry port, Ethiopia, 2018. Methods: A cross-sectional study was conducted among systematically selected 422 long distance truck drivers at Modjo dry port, Ethiopia from February to March, 2018. Data was collected through face to face individual interview using structured questionnaire adapted from standardized Nordic questionnaire for the analysis of musculoskeletal symptoms. The data was entered using epi-data version 4.2.0.0, cleaned and analyzed using SPSS version 20 statistical software for windows. Binary logistic regression was computed to determine association using crude and adjusted odds ratios at 95% confidence intervals. Independent variables found significant with pvalue less than 0.05 at the bivariate level were included in the multivariable logistic regression model to control for potential confounding. Results: The prevalence of LBP was found to be 65%. The study found monthly income above 5350 ETB [AOR = 3.07, 95% CI (1.76-5.33), P = 0.000], smoking cigarette[AOR = 2.28, 95% CI (1.25-4.17), P = 0.007], physical inactivity [AOR = 2.14, 95% CI (1.26-3.61), P = 0.005], irregular mealtime [AOR = 1.73, 95% CI (1.02-2.93), P = 0.042], chronic diseases other than LBP [AOR = 2.16, 95% CI (1.28-3.65), P = 0.004], frequent lifting or carrying heavy objects [AOR = 3.25, 95% CI (1.83-5.75), P = 0.000], perceived improper sitting posture while driving [AOR = 1.95, 95% CI (1.17-3.25), P = 0.011] and perceived job stress [AOR = 2.00, 95% CI (1.09-3.70), P = 0.026] were predictors of low back pain. Conclusion: This finding shows the public health importance of low back pain among long distance truck drivers in Ethiopia. Individual factors largely accounted for the development of low back pain, hence orientation on these modifiable risk factors and regular follow up on safety procedures should be considered to mitigate the problem.

description: We present direct constraints on galaxy intrinsic alignments using the Dark Energy Survey Year 3 (DES Y3), the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) and its precursor, the Baryon Oscillation Spectroscopic Survey (BOSS). Our measurements incorporate photometric red sequence (redMaGiC) galaxies from DES with median redshift $z\sim0.2-1.0$, luminous red galaxies (LRGs) from eBOSS at $z\sim0.8$, and also a SDSS-III BOSS CMASS sample at $z\sim0.5$. We measure two point intrinsic alignment correlations, which we fit using a model that includes lensing, magnification and photometric redshift error. Fitting on scales $6

description: Σκοπός της παρούσας εργασίας ήταν να εξετάσει την επίδραση της κίνησης των άνω ακρών κατά το λάκτισμα στο ποδόσφαιρο. Δέκα ποδοσφαιριστές (n=10) συμμετείχαν στην έρευνα όπου εκτέλεσαν 4 είδη λακτίσματος με διαφορετικές θέσεις των άνω άκρων. Η πρώτη ήταν με ελεύθερη κίνηση των χεριών(FREE KICK), η δεύτερη με τα χεριά κολλημένα στο σώμα(HANDOFF), η τρίτη με το δεξί χέρι κολλημένο στο σώμα και το αριστερό χέρι ελεύθερο(HOR) και τέλος το αριστερό χέρι κολλημένο στο σώμα και ελεύθερο το δεξί χέρι(HOL). Οι συμμετέχοντες αξιολογήθηκαν ως προς 1) την ταχύτητα της μπάλας σε κάθε είδος λακτίσματος 2) τις δυνάμεις που ασκούσε το πόδι στήριξης και τέλος 3) τις γωνίες του γόνατος, ισχίου, ποδοκνημικής κατά την φάση όπλισης, επαφή μπάλας και κατά το follow through. Τα αποτελέσματα έδειξαν ότι ο μέσος όρος ταχύτητας ήταν μεγαλύτερος στο HOR σε σχέση με τις άλλες 3 συνθήκες. Η ανάλυση διακύμανσης (ANOVA) έδειξε ότι δεν υπάρχει στατιστικά σημαντική διαφορά στις γωνίες της ποδοκνημικής σε όλες τις φάσεις του λακτίσματος(Φ.Ο, Ε.Β, F.T) αλλά και σε όλα τα είδη του λακτίσματος. Το ίδιο ισχύει για το γόνατο για την φάση όπλισης και το follow through ενώ κατά την φάση επαφής της μπάλας υπάρχει στατιστική σημαντική διαφορά (p=0.004). Επίσης το ίδιο ισχύει για το ισχίο για την φάση όπλισης και το follow through ενώ κατά την φάση επαφής μπάλας υπάρχει στατιστική σημαντική διαφορά (p=0.004). Επομένως η κίνηση των χεριών δεν επηρεάζουν το λάκτισμα.
description: The purpose of this paper was to examine the effect of upper limb movements during kicking in football. Ten footballers (n = 10) participated in the study where they performed 4 species kicked with different positions of the upper extremities. The first was with free movement of the hands (FREE KICK), the second with the hands glued to the body (HANDOFF), the third with the right hand glued to the body and the left hand free (HOR) and finally the left hand glued to the body and free right hand (HOL). The participants were evaluated in terms of 1) the speed of the ball in each type of kick 2) the forces exerted by the foot supports and finally 3) the angles of the knee, hip, ankle during the phase of arms, contact of the ball and during follow through. The results showed that the serum velocity was higher in HOR than in the other 3 conditions. The analysis of variance (ANOVA) showed that there is no statistically significant difference in the angles of the ankle in all the phase of the kick (F.O, E.B, F.T) but also in all types of kick. The same applies to the knee for the arming phase and the follow through while during the ball contact phase there is a statistically significant difference (p = 0.004). The same is true for the hip for the arming phase and the follow through while during the ball contact phasethere is a statistically significant difference (p = 0.004). Therefore the movement of the hands does not affect the kick.

description: Developing tissues are sequentially patterned by extracellular signals that are turned on and off at specific times. In the zebrafish hindbrain, fibroblast growth factor (Fgf) signalling has different roles at different developmental stages: in the early hindbrain, transient Fgf3 and Fgf8 signalling from rhombomere 4 is required for correct segmentation, whereas later, neuronal Fgf20 expression confines neurogenesis to specific spatial domains within each rhombomere. How the switch between these two signalling regimes is coordinated is not known. We present evidence that the Zbtb16 transcription factor is required for this transition to happen in an orderly fashion. Zbtb16 expression is high in the early anterior hindbrain, then gradually upregulated posteriorly and confined to neural progenitors. In mutants lacking functional Zbtb16, fgf3 expression fails to be downregulated and persists until a late stage, resulting in excess and more widespread Fgf signalling during neurogenesis. Accordingly, the spatial pattern of neurogenesis is disrupted in zbtb16 mutants. Our results reveal how the distinct stage-specific roles of Fgf signalling are coordinated in the zebrafish hindbrain.

description: In the recent years self-testing has grown into a rich and active area of study with applications ranging from practical verification of quantum devices to deep complexity theoretic results. Self-testing allows a classical verifier to deduce which quantum measurements and on what state are used, for example, by provers Alice and Bob in a nonlocal game. Hence, self-testing as well as its noise-tolerant cousin -- robust self-testing -- are desirable features for a nonlocal game to have. Contrary to what one might expect, we have a rather incomplete understanding of if and how self-testing could fail to hold. In particular, could it be that every 2-party nonlocal game or Bell inequality with a quantum advantage certifies the presence of a specific quantum state? Also, is it the case that every self-testing result can be turned robust with enough ingeniuty and effort? We answer these questions in the negative by providing simple and fully explicit counterexamples. To this end, given two nonlocal games $\mathcal{G}_1$ and $\mathcal{G}_2$, we introduce the $(\mathcal{G}_1 \lor \mathcal{G}_2)$-game, in which the players get pairs of questions and choose which game they want to play. The players win if they choose the same game and win it with the answers they have given. Our counterexamples are based on this game and we believe this class of games to be of independent interest.

description: We report the detection of a new feature at the centre of NGC 1275 in the Perseus cluster, hosting the radio source 3C 84. This feature emerges ~ 2 mas (~ 0.8 pc) north of the central core in recent 15 and 43 GHz VLBA images, and seems to be the counterjet to a known radio jet expanding to the south of the core. Apparently, the two jets were born through an outburst around 2005. From the ratio of the apparent lengths of the two jets from the core, we found that the jet angle to the line of sight is θ=65^\circ\pm 16^\circ, which is not much different from the angle of the outer jets generated by an activity around 1959 and constrains theories on gamma-ray emission from jets. The new northern jet has a strongly inverted spectrum in contrast with the southern jet. This suggests that the central black hole is surrounded by a subparsec-scale accretion disk with the density of >~ 10^5 cm^-3. The brightness of the counterjet suggests that the disk is highly inhomogeneous. The ambient gas density in the direction of the jet is ~ 8 cm^-3 if the current jet activity is similar to the past average.

description: Though sexual violence is increasingly being recognized as a problem in different countries there is a knowledge gap regarding this problem in Ethiopia which prompt the conduct of this study. Focused Group discussion and cross sectional school-based survey using self administered anonymous questionnaire was conducted in Addis Ababa and Western Shoa high school students from January 1 to January 15, 1996 to determine prevalence, factors related to, reported outcome and attitude of high school students towards sexual violence. A total of 2773 students were involved in the study. A prevalence rate of completed rape and attempted rape among female students was 5.2% and 10.1% respectively. Eighty nine(6.5%) of male students admitted to rape a girl while 181(13.2%) claimed to attempt rape. Sexual harassment was reported in 74.3% of female students. Unwanted pregnancy and different forms of psychiatric disturbance were reported among rape victims which signifies the role of rape in these health problems. There was significantly higher proportion of rape among female students who were aged more than 20 (OR=6.00 95% I, 27.57), from divorced family (OR=2.46 95% CI:1.31, 4.5), who were living alone (OR=4.88 95% CI:2.17,10.71), who were living with a relative (OR=2.49 95% CI:1.10, 5.46) and who had a boy friend (OR=7.86 95% CI:4.56, 13.64). There was a significantly higher proportion of committing rape among males who were living in rural areas, who were living alone and who had a girl friend (OR=0.43 95% CI:0.26-0.69; OR=2.44 95% CI:1.16, 5.02; OR=4.48 95% CI:2.82,7.11 respectively). Substance use and physical force were also contributing to the offence. On attitude towards sexual violence major proportion of students believe that it is" acceptable" to force a girl to have intercourse in certain conditions. Both the survey and focus group discussion address that sexual violence is a serious problem and not a rare event among high school students. Based on these findings it is recommended that sexual violence deserves due attention and remedial action from concerned bodies and further qualitative study is recommended to have in depth knowledge.

description: Purpose: Implausibly high algorithm-identified cancer incidence within a new user study after medication initiation may result from increased healthcare utilization (HU) around initiation (“catch-up care”) that increases diagnostic opportunity. Understanding the relationships between HU prior to and around initiation and subsequent cancer rates and timing is important to avoiding protopathic bias. Methods: We identified a cohort of 417 458 Medicare beneficiaries (2007–2014) aged ≥66 initiating an antihypertensive (AHT) after ≥180 days of non-use. Initiators were stratified into groups of 0, 1, 2–3, and ≥4 outpatient visits (OV) 60–360 days before initiation. We calculated algorithm-identified colorectal cancer (aiCRC) rates stratified by OVs and time since AHT initiation: (0–90, 91–180, 181–365, 366–730, and 731+ days). We summarized HU -360/+60 days around AHT initiation by aiCRC timing: (0–29, 30–89, 90–179, and ≥180 days). Results: AiCRC incidence (311 per 100 000 overall) peaked in the first 0–90 days, was inversely associated with HU before initiation, and stabilized ≥180 days after AHT initiation. Catch-up care was greatest among persons with aiCRCs identified <30 days in follow-up. Catch-up care magnitude decreased as time to the aiCRC date increased, with aiCRCs identified ≥180 days after AHT initiation exhibiting similar HU compared with the full cohort. Conclusion: Lower HU before—and increased HU around AHT initiation—seem to drive excess short-term aiCRC incidence. Person-time and case accrual should only begin when incidence stabilizes. When comparison groups within a study differ by HU, outcome-detection bias may exist. Similar observations may exist in other settings when typical HU is delayed (e.g., cancer screening during SARS-CoV-2).

description: In order to probe the dynamics of contact-line motion, we study the macroscopic properties of sessile drops deposited on and then aspirated from carefully prepared horizontal surfaces. By measuring the contact angle and drop width simultaneously during droplet removal, we determine the changes in the shape of the drop as it depins and recedes. Our data indicate that there is a force which opposes the motion of the contact line that depends both on the amount of time that the drop has been in contact with the surface and on the withdrawal rate. For water on silanized glass, we capture the experimentally observed behavior with an overdamped dynamical model of contact-line motion in which the phenomenological drag coefficient and the assumed equilibrium contact angle are the only inputs. For other liquid/substrate pairs, the observed contact-line motion suggests that a maximum static friction force is important in addition to damping. The dependence on time of contact and withdrawal rate, reminiscent of rate-and-state friction between solid surfaces, is qualitatively consistent across three substrate-liquid pairs.

description: In this paper we consider the class of graphs which are redundantly $d$-rigid and $(d+1)$-connected but not globally $d$-rigid, where $d$ is the dimension. This class arises from counterexamples to a conjecture by Bruce Hendrickson. It seems that there are relatively few graphs in this class for a given number of vertices. Using computations we show that $K_{5,5}$ is indeed the smallest counterexample to the conjecture.

description: The non-equilibrium dynamics of small boson ensembles in a one-dimensional optical lattice is explored upon a sudden quench of an additional harmonic trap from strong to weak confinement. We find that the competition between the initial localization and the repulsive interaction leads to a resonant response of the system for intermediate quench amplitudes, corresponding to avoided crossings in the many-body eigenspectrum with varying final trap frequency. In particular, we show that these avoided crossings can be utilized to prepare the system in a desired state. The dynamical response is shown to depend on both the interaction strength as well as the number of atoms manifesting the many-body nature of the tunneling dynamics.

description: Στην παρούσα εργασία διερευνάται η έννοια των ανθρωπίνων δικαιωμάτων σε σχέση με το πως αυτά υλοποιούνται εμπράκτως στο πλαίσιο της διαχείρισης της προσφυγικής κρίσης στην Ελλάδα, κατά την περίοδο 2015-2022. Το πρώτο μέρος αφιερώνεται στην κριτική προσέγγιση της παραδοσιακής εννοιολόγησης των ανθρωπίνων δικαιωμάτων από τους διανοητές της Αρχαιότητας, του Μεσαίωνα και του Διαφωτισμού, υπό το πρίσμα νεότερων φιλοσοφικών προσεγγίσεων. Στο δεύτερο μέρος εξετάζεται η προσφυγική κρίση στην Ελλάδα (2015-2022), ως ένα παράδειγμα «νεκροπολιτικής». Δηλαδή, ως μίας πολιτικής στρατηγικής που αποστερεί τη ζωή των προσφύγων/μεταναστών από τα ποιοτικά και πολιτικά χαρακτηριστικά της. Στο τρίτο μέρος αναλύεται η ιδέα των ανοιχτών συνόρων ως λύση στα προβλήματα των σύγχρονων, διεθνών, πληθυσμιακών μετακινήσεων, εντασσόμενη στο πλαίσιο της παγκοσμιοποίησης και εξεταζόμενη παράλληλα με την ιδέα του «παγκοσμίου ανθρώπου».
description: In the present thesis I examine the concept of human rights in relation to how those actively materialize in the context of the refugee crisis management in Greece, during the period of 2015-2022. I dedicate the first part in the newest critical philosophical approach of the traditional human rights conceptualization, which is based on the philosophical perspectives created in Antiquity, Middle Ages and Enlightenment. In the second part I examine the refugee crisis in Greece (2015-2022), as a paradigm of necropolitics, a political strategy that negates the political and qualitative aspects of refugees’/migrants’ life. In the third part I analyze the idea of open borders as a solution to the problems that global population movements create and as it is seen in the context of globalization and «universal human» concept.

description: Path dependency as it is described by Arthur and David portrays technological developments as historically embedded, emergent processes. In contrast, Garud and Karnøe's notion of path creation emphasises the role of strategic change and deliberate action for the development of new technologies. In this article, we integrate both concepts into a general understanding of path processes which accounts for emergent as well as deliberate modes of path constitution. In addition, we distinguish between three consecutive phases of technological path developments. Both conceptualisations are used to create an analytical grid against which empirical cases of path processes can be matched. Based on this general understanding, we further outline how concepts from science and technology studies and institutional theory can help to elaborate the role of deliberate action and emergence in the stabilisation of technological paths over time.

description: Η επιλογή της παρούσας μελέτης στηρίχθηκε στη συνθήκη της πανδημίας του Covid-19 , η οποία εξαπλώθηκε σε παγκόσμιο επίπεδο στις αρχές του 2020 και αποτελεί μία ερευνητική πρόκληση ως προς τα αποτελέσματά της σε διάφορους τομείς της ανθρώπινης ζωής. Σκοπός της έρευνας είναι να αξιολογήσει το στρες που βιώνουν οι γονείς κατά την περίοδο αυτής της πρωτόγνωρης συνθήκης. Η υπόθεση της έρευνας βασίστηκε στην πεποίθηση ότι οι γονείς παιδιών με αναπηρία ή ειδικές εκπαιδευτικές ανάγκες, οι οποίοι συνήθως βιώνουν μεγαλύτερα επίπεδα στρες από τους γονείς παιδιών τυπικής ανάπτυξης, αναμένεται να αναπτύξουν μεγαλύτερο στρες κατά τη διάρκεια της πανδημίας του SARS-CoV-2. Αποτελεί μία πρωτογενή έρευνα, κατά την οποία ο συλλέχθηκαν στοιχεία σχετικά με το βαθμό που επηρεάζει η αναπηρία ή η ειδική εκπαιδευτική ανάγκη του παιδιού το στρες που αναπτύσσει ο γονιός κατά την περίοδο της πανδημίας του SARS- CoV-2. Τα δεδομένα της μελέτης συγκεντρώθηκαν μέσω συμπλήρωσης ερωτηματολογίου από ένα δείγμα 205 γονιών. Το δείγμα προέκυψε από τους καταλόγους φοιτούντων παιδιών σε γενικά και ειδικά σχολεία και τα αποτελέσματα της έρευνας προέκυψαν μέσω στατιστικής ανάλυσης μελέτης.
description: The selection of the present study was based on the Covid-19 pandemic, which spread worldwide in early 2020 and is a research challenge in terms of its results in various areas of human life. The purpose of the study is to assess the stress experienced by parents during this period of unprecedented condition. The research hypothesis was based on the belief that parents of children with disabilities or special educational needs, who typically experience higher levels of stress than parents of children with normal development, are expected to develop greater stress during the SARS-CoV-2 pandemic. It is a primary study, in which data was collected on the degree to which the parent's disability or special educational need affects the stress that the parent develops during the SARS-CoV-2 pandemic period. Study data were collected by completing a questionnaire from a sample of 205 parents. The sample was obtained from the lists of children attending general and special schools and the results of the research were obtained through a statistical analysis of a study.

description: Based on first-principles calculations, we investigate the energetic stability and the electronic properties of (i) a single layer phosphorene (SLP) adsorbed on the amorphous sio2 surface (SLP/a-sio2), and (ii) the further incorporation of water molecules at the phosphorene/a-sio2 interface. In (i), we find that the phosphorene sheet bonds to a-sio2 through van der Waals interactions, even upon the presence of oxygen vacancy on the surface. The \slp/a-\sio\ system presents a type-I band alignment, with the valence (conduction) band maximum (minimum) of the phosphorene lying within the energy gap of the a-\sio\ substrate. The structural, and the surface-potential corrugations promote the formation of electron-rich and -poor regions on the phosphorene sheet and at the SLP/a-sio2 interface. Such charge density puddles have been strengthened by the presence of oxygen vacancies in a-sio2. In (ii), due to the amorphous structure of the surface, we have considered a number of plausible geometries of water embedded in the SLP/a-sio2 interface. There is an energetic preference to the formation of hydroxyl (OH) groups on the a-sio2 surface. Meanwhile, upon the presence of oxygenated water or interstitial oxygen in the phosphorene sheet, we find the formation of metastable OH bonded to the phosphorene, and the formation of energetically stable P--O--Si chemical bonds at the SLP/a-sio2 interface. Further x-ray absorption spectra (XAS) simulations have been done, aiming to provide additional structural/electronic informations of the oxygen atoms forming hydroxyl groups or P--O--Si chemical bonds at the interface region.

description: This paper brings together thinking from the history of science, science and technology studies and social/cultural anthropology to better understand how human diversity is handled in everyday practices in science and beyond. Our aim is to take the social and historical contingency of practice as a starting point and to focus on the patterning of practice, which arises from the constraints of socio-material alignments and leads to the co-production of diversity. Under the headings of race and ethnicity, sorting practices with regards to human diversity have been at the centre of anthropological thinking and critique since the age of Enlightenment. Constructivist critique has insisted on understanding "race" as a social construct and warned of reifying differences of a socio-cultural making. This critique has so far not been particularly fruitful in dealing with human biological difference as produced in different everyday practices in science and beyond. Recently, molecular genetics have reinvigorated the interest to stratify human populations into subpopulations to improve drug development and targeting, to ascertain vulnerabilities and plasticity, to adjust nutritional intake or therapeutic strategies or to trace ethnic ancestries. We suggest that the shortcomings of constructivist critique in the face of these latest developments are due to its focus on theoretical concepts and self-descriptions rather than the practices and their implicit logics within and outside science proper. By employing Hacking's concepts of 'making up people' and 'looping', Rabinow's 'biosociality', as well as Callon's concept of 'translation', we hope to show the interactive dynamics of classification and response which take place at the interface between different knowledge practices. We trace translations through the life sciences into clinical practice and beyond into different social constellations, involving medical practice, made-up people and social bodies in order to show how human diversity is produced in practice. We put an emphasis on the different roles that biohistorical narratives, standardised packages and forms of resistance and appropriation play within these constellations.

Epidemiological Assessment of Determinants and Causes of under five Child Mortality in Jimma town: Is HIV/AIDS influencing the pattern of child mortality?
Creators: name: Girma, Belaineh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2004

description: Background .About 11 million children younger than5 years still die every year even after a substantial decline in child mortality had occurred. The findings that are available so far show that about two third of child deaths could be prevented by interventions that are available today and feasible for implementation in low income countries .The identification of determinants of child mortality is a crucial step in planning and implementation of interventions . Objective: To assess the determinants and causes of child mortality Methods. The study utilized a case control study design, Cases and controls were identified by population based survey. The study was conducted in Jimma Town from October to November 2004 .The variables included were socioeconomic, behavioral, nutritional, environmental and disease history. The data was collected using structured questionnaire which include standardized verbal autopsy tool. Results: Muslim religion(OR=3.41,95%CI(1.37,8.46)) Dawro(OR=6.51,95%CI(2.13,19.88)) and Yem (OR=4.25,95%CI(1.09,116.48)), never breast fed, (OR=13.74,95%CI(3.34,56.42)) not vaccinated children(OR=.26,95%CI(0.10,0.67)) and (OR=3.34,95%CI(1. 27,8.76)) children with mother's having more than five children are significantly associated with child death . Pneumonia, Malaria and gastroenteritis were leading causes of death. Malnutrition (38%)and HIV/AIDS(2.8%) had contributed to a significant proportion deaths. Conclusion and recommendations: immunization, parity and breast feeding were found to be protective from childhood deaths. Despite the limitations of Verbal autopsy, the determination of causes of death using verbal autopsy is of greater importance and value to public health. Strengthening the child survival initiatives namely universal child immunization, family planning and breast feeding are strongly recommended.
