description: The first order antiferromagnetic (AFM) to ferromagnetic (FM) transition in the functional material Fe49(Rh0.93Pd0.07)51 has been studied at low temperatures and high magnetic fields. We have addressed the non-monotonic variation of lower critical field required for FM to AFM transition. It is shown that critically slow dynamics of the transition dominates below 50 K. At low temperature and high magnetic field, state of the system depends on the measurement history resulting in tunable coexistence of AFM and FM phases. By following cooling and heating in unequal magnetic field (CHUF) protocol it is shown that equilibrium state at 6 Tesla magnetic field is AFM state. Glass like FM state at 6 T (obtained after cooling in 8 T) shows reentrant transition with increasing temperature; viz. devitrification to AFM state followed by melting to FM state.

description: Insulating particles can become highly electrified during powder handling, volcanic eruptions, and the wind-blown transport of dust, sand, and snow. Measurements in these granular systems have found that smaller particles generally charge negatively, while larger particles charge positively. These observations are puzzling, since particles in these systems are generally chemically identical, and thus have no contact potential difference. We show here that simple geometry leads to a net transfer of electrons from larger to smaller particles, in agreement with these observations. We integrate this charging mechanism into the first quantitative charging scheme for a granular system of identical insulators, and show that its predictions are in agreement with measurements. Our theory thus seems to provide an explanation for the hitherto puzzling phenomenon of the size-dependent charging of granular systems of identical insulators.

description: Using deep HST/ACS observations of the core of the Perseus Cluster, we identify a large population of dwarf elliptical galaxies down to M_V = -12. All these dwarfs are remarkably smooth in appearance, showing no evidence for internal features that could be the result of tidal processes or star formation induced by the cluster potential. Based on these observations and the relatively large sizes of these dwarfs, we argue that at least some must have a large dark matter component to prevent their disruption by the cluster potential. We further derive a new method to quantify the dark matter content of cluster dSphs without the use of kinematics, which are impossible to obtain at these distances. We find that mass-to-light ratios for dwarfs in the core of the Perseus Cluster are comparable to those found for Local Group dSphs, ranging between M/L ~ 1 and 120. This is evidence that dwarf spheroidals reside in dark matter subhalos that protect them from tidal processes in the cores of dense clusters.

description: Let K be the space of long j-knots in R^n. In this paper we introduce a graph complex D and a linear map I from D to the de Rham complex of K via configuration space integral, and prove that (1) when both n>j>=3 are odd, the map I is a cochain map if restricted to graphs with at most one loop component, (2) when n-j>=2 is even, the map I is a cochain map if restricted to tree graphs, and (3) when n-j >=3 is odd, the map I added a correction term produces a (2n-3j-3)-cocycle of K which gives a new formulation of the Haefliger invariant when n=6k, j=4k-1 for some k.

description: There are several well-known methods that one can use to construct Hadamard matrices from base sequences BS(m,n). In view of the recent classification of base sequences BS(n+1,n) for n <= 30, it may be of interest to show on an example how prolific these methods are. For that purpose we have selected the Hadamard matrices of order 60. By using these methods and the transposition map we have constructed 1759 nonequivalent Hadamard matrices of order 60.

description: Background: We examined the associations between accelerometry-measured physical activity (PA) and incidence of 13 cancers among a cohort of postmenopausal women. Methods: In this prospective study, 6382 women wore ActiGraph GT3X+ accelerometers at the hip for up to 7 days during 2012–2013, and were followed over a median of 4.7 years for diagnosis of 13 invasive cancers. Calibrated intensity cut points were used to define minutes per day of total, light and moderate-to-vigorous PA. We used multivariable Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for tertiles, and one-standard deviation (SD) unit increments of PA exposures in relation to cancer incidence. We examined effect measure modification by age, race/ethnicity, body mass index and smoking history. Results: The highest (vs. lowest) tertiles of total, light and moderate-to-vigorous PA were associated with covariate-adjusted HRs of 0.72 (95% CI = 0.53–0.97), 0.81 (95% CI = 0.60–1.09) and 0.66 (95% CI = 0.48–0.91), respectively. In age-stratified analyses, HRs for total PA were lower among women <80 years (HRper one-SD = 0.75, 95% CI = 0.63–0.90) than among women ≥80 years (HRper one-SD = 0.99, 95% CI = 0.82–1.18) (PInteraction = 0.03). Race/ethnicity, BMI and smoking did not strongly modify these associations. Conclusions: Engaging in physical activity may play a beneficial role in the prevention of certain cancers in older women.

description: Background: Daily step counts is an intuitive metric that has demonstrated success in motivating physical activity in adults and may hold potential for future public health physical activity recommendations. This review seeks to clarify the pattern of the associations between daily steps and subsequent all-cause mortality, cardiovascular disease (CVD) morbidity and mortality, and dysglycemia, as well as the number of daily steps needed for health outcomes. Methods: A systematic review was conducted to identify prospective studies assessing daily step count measured by pedometer or accelerometer and their associations with all-cause mortality, CVD morbidity or mortality, and dysglycemia (dysglycemia or diabetes incidence, insulin sensitivity, fasting glucose, HbA1c). The search was performed across the Medline, Embase, CINAHL, and the Cochrane Library databases from inception to August 1, 2019. Eligibility criteria included longitudinal design with health outcomes assessed at baseline and subsequent timepoints; defining steps per day as the exposure; reporting all-cause mortality, CVD morbidity or mortality, and/or dysglycemia outcomes; adults ≥18 years old; and non-patient populations. Results: Seventeen prospective studies involving over 30,000 adults were identified. Five studies reported on all-cause mortality (follow-up time 4-10 years), four on cardiovascular risk or events (6 months to 6 years), and eight on dysglycemia outcomes (3 months to 5 years). For each 1000 daily step count increase at baseline, risk reductions in all-cause mortality (6-36%) and CVD (5-21%) at follow-up were estimated across a subsample of included studies. There was no evidence of significant interaction by age, sex, health conditions or behaviors (e.g., alcohol use, smoking status, diet) among studies that tested for interactions. Studies examining dysglycemia outcomes report inconsistent findings, partially due to heterogeneity across studies of glycemia-related biomarker outcomes, analytic approaches, and sample characteristics. Conclusions: Evidence from longitudinal data consistently demonstrated that walking an additional 1000 steps per day can help lower the risk of all-cause mortality, and CVD morbidity and mortality in adults, and that health benefits are present below 10,000 steps per day. However, the shape of the dose-response relation is not yet clear. Data are currently lacking to identify a specific minimum threshold of daily step counts needed to obtain overall health benefit.

description: New CCD photometry during 4 successive years from 2005 is presented for the eclipsing binary GW Cep, together with reasonable explanations for the light and period variations. All historical light curves, obtained over a 30-year interval, display striking light changes, and are best modeled by the simultaneous existence of a cool spot and a hot spot on the more massive cool component star. The facts that the system is magnetically active and that the hot spot has consistently existed on the inner hemisphere of the star indicate that the two spots are formed by (1) magnetic dynamo-related activity on the cool star and (2) mass transfer from the primary to the secondary component. Based on 38 light-curve timings from the Wilson-Devinney code and all other minimum epochs, a period study of GW Cep reveals that the orbital period has experienced a sinusoidal variation with a period and semi-amplitude of 32.6 yrs and 0.009 d, respectively. In principle, these may be produced either by a light-travel-time effect due to a third body or by an active magnetic cycle of at least one component star. Because we failed to find any connection between luminosity variability and the period change, that change most likely arises from the existence of an unseen third companion star with a minimum mass of 0.22 $M_\odot$ gravitationally bound to the eclipsing pair.

Untersuchungen zur Bruchtektonik in der Zentralägäis

description: Die vorliegende Arbeit soll einen Beitrag zur Erfassung und Analyse der postalpinen Bruchtektonik des zentralägäischen Raumes liefern. Das Arbeitsgebiet umfaßt Teile aller drei Stockwerke der alpidischen Helleniden, insbesondere der West- und Zentralhellenischen Decken. Das Bruchmuster mußte in zwei grundsätzlich verschiedenen Bereichen erfaßt werden - auf dem Festland und im Meer. Die seit einigen Jahren zur Verfügung stehenden Satellitenbilder ermöglichten eine flachendeckende Interpretation der Landgebiete des Untersuchungsareals. In wichtigen Teilgebieten wurden sie Luftbild-Auswertungen gegenübergestellt sowie durch Geländekontrollen überprüft. Dieser dreistufige Vergleich wurde für den Westteil des Untersuchungsgebietes, in der südöstlichen Argolis und der Lakonischen Halbinsel, im Zentrum auf der Insel Naxos und im Osten auf den Inseln Samos und Ikaria durchgefuhrt. Unter Berücksichtigung der Eigenheiten der verschiedenen Auswertungsmethoden konnten in der Satellitenbild-Auswertung eine große Anzahl der Lineationen bewertet und Bruchzonen von regionaler Bedeutung herausgefiltert werden. Für die vom Meer bedeckten Gebiete mußte das Bruchmuster aus der Morphologie des Meeresbodens, die sich in Isobathenkarten wiederspiegelt, gewonnen werden. Von großmaßstäbigen Seekarten ausgehend, konnten insbesondere der Schelfbereich und über diesen hinaus große Teile des Meeresbodens im Bereich der zentralägäischen Inselbrücke relativ detailliert dargestellt werden, über eine daraus entwickelte Hangneigungskarte wurden die sich auf dem Meeresboden abzeichnenden Bruchspuren erfaßt. Die Interpretationsergebnisse der verschiedenen Auswertungsmethoden werden für alle Teilgebiete der Region getrennt vorgestellt und verknüpft betrachtet. Danach zeigt das Bruchmuster im Einzelnen ein recht differenziertes Bild, doch lassen sich übergreifende Trends erkennen: Im Westen dominieren zwischen dem Ost-Peloponnes und dem Westrand des Kykladen-Plateaus Bruchzonen in der NNU/SSE-Richtung. östlich davon herrschen dagegen bis zur kleinasiatischen Küste Bruchzonen vor, die ENE/WSW bis NE/SW verlaufen. Im nordöstlichen Peloponnes und auf der Landbrücke von Korinth sowie im Bereich der Menderes-Gräben und auf Samos sind überwiegend E/W streichende Bruchzonen vertreten. Im Gegensatz zu bisher veröffentlichten neotektonischen Ergebnissen enthält das Bruchmuster auch innerhalb des südägäischen Bogens Blattverschiebungen… Ein relativ ausgeglichenes Spannungsfeld im Bereich des ägäischen Bogens legt neben Subduktion und back-arc basin eine weitere Beeinflussung der Kruste dieses Raumes nahe, die in der Westdrift der Arabischen Platte denkbar wäre.

Structural geology of Empire mine, Empire Development Company Limited, Port McNeill, B.C.

Year: 2011

description: Empire mine is located on north-central Vancouver Island about two miles south of Benson Lake; Orebodies are typical of the many contact metasomatic iron deposits of the West Coast of British Columbia. They occur in Bonanza volcanic rocks and Quatsino limestone of Upper Triassic age near the margins of a small granitic stock of intermediate composition. Structural controls at Empire mine are in part the configuration of the intrusion contact and in part the intersection of steep northeasterly faults with (a) folded and fractured volcanic rocks at the Merry Widow deposit and (b) with swarms of northwesterly striking greenstone dykes in the Kingfisher deposits. The Kingfisher fault transects both the Merry Widow and Kingfisher orebodies as well as the West Pipe and is considered one of the main channels for mineralizing solutions. Relatively intense folding occurs near margins of the Coast Copper stock. In the Merry Widow area, plot of poles to bedding on Schmidt equal area net indicate a north-northwesterly plunging major fold. Superimposed on this are minor drag and disharmonic folds. Fold axes all strike northerly sub-parallel to the intrusion contact and folding is considered a direct response to emplacement of the Coast Copper stock. Relation between intrusive greenstone and local folding would suggest that final stages of Bonanza volcanism, regional folding and emplacement of the stock with local folding and mineralization may be nearly contemporaneous.

description: Esimene neerusiirdamine Eestis toimus Tartus Toome Haavakliinikus 20. septembril 1968. Selle eelduseks olid hemodialüüsi juurutamine 1966. aastal, pikaajalises teadvusetus seisundis haigete ravi kogemus ja ajusurma kriteeriumide rakendamine närvikliiniku hingamiskeskuses ning kirurgide, neuroloogide ja kohtuarstide hea koostöö. Siirdamistegevuse algaastail olid tulemused sageli ebarahuldavad, valitses ka teatud skeptitsism. Hemodialüüsi võimaluste paranemine, moodsate koesobivusproovide juurutamine ja edusammud immunosupressioonravis võimaldasid ravitulemusi oluliselt parandada. Nüüdseks elab Eestis 380 siiratud neeruga patsienti, kokku on tehtud 800 neerusiirdamist. Neerusiirdamiste arvult miljoni elaniku kohta on Eesti euroliidu maade seas keskmisest paremal kohal.

description: Wine was an ever-present commodity that permeated the Mediterranean throughout antiquity; in particular, settlements in the eastern Mediterranean produced substantial quantities of wine for a variety of uses in Late Antiquity. This study devotes itself to the viticulture of two such settlements, Antiochia ad Cragum and Delos, and uses the results of surface survey and excavation to elucidate their potential integration within the agricultural boom of the 5th-7th centuries CE. Interdisciplinary and ethnographic data supplements the main archaeological catalogue in order to provide a well-rounded understanding of production and use. The publication of an excavated vinicultural vat in Rough Cilicia for the first time, along with the first complete discussion of the paleochristian viticultural industry on Delos, underscores the importance of this project.The bulk of the thesis is devoted to a catalogue of individual vinicultural installations from each site, which includes a detailed analysis and description of their architecture and features. This emphasises the significant quantity of data that such individual analyses can reveal, in terms of construction methods, spatial setting, regional habits in press design and wine production. The remaining chapters combine archaeological features with interdisciplinary data situated within a broad discussion to interpret production at these settlements. This demonstrates how such data can be extrapolated and combined with related evidence to illuminate trends regarding agricultural production, viticultural quantification, religious habits, regional interconnectivity, trade and the economy.The combined catalogue, analysis and discussion reinforce the noteworthy position viticulture held in Late Antiquity as an agricultural endeavour, socio-cultural and economic factor engrained within eastern Mediterranean settlements.

description: All people need to engage in routine physical activity and children require it daily. Playgrounds are settings designed for children to be physically active, yet there has been little research assessing which play elements and structures are associated with more moderate-to-vigorous physical activity (MVPA) among both youth and adults. We conducted a national study of neighborhood parks with the goal of identifying factors that promote more MVPA. We selected a nationally representative sample of 162 parks between 3 and 22 acres in 25 U.S. cities with a population >100,000. We used direct observation to measure MVPA in 147 playgrounds during spring and summer of 2016, documented playground characteristics and assessed hours of use and MVPA by age group and gender. We analyzed data using descriptive statistics and generalized linear models. The most common play elements and structures were slides and ladders (92% of parks) and swings (81%); elements supporting balancing, crawling, spinning, sand and water play were in <30% of playgrounds. Each additional play element was associated with about 50% more users and 50% more MVPA. Spinning structures and splash pads were associated with more playground use and more MVPA. Playgrounds with signage advertising park programs and on-site restrooms had more person-hours of use, but only half the parks had restrooms and <30% had signage. To address insufficient physical activity, upgrades to playgrounds should include restrooms, structures that support a wide variety of movements, and elements that also encourage adults to be active.

Haiguse algstaadiumis võivad patsiendil igasugused kaebused puududa ning see põhjustab sageli diagnoosi ja ravi hilinemise. Haiguse süvenemise korral ohustavad patsienti nefrootiline sündroom ja selle tüsistused ning terminaalne neerupuudulikkus. Glomerulonefriidi lõpliku diagnoosi, ravitaktika ja prognoosi hindamise aluseks on neerubiopsia. Primaarse glomerulonefriidi eri vormid vajavad erinevat ravi, kuid haiguse progresseerumist ja neerukahjustuse süvenemist lõppstaadiumis neerupuudulikkuseni on sageli võimalik aeglustada. Paljud patsiendid ei vaja pidevat aktiivset ravi, kuid remissioonifaasis on  vajalik haigete jälgimine ja regulaarne kontroll (uriini analüüs, vererõhk, neerufunktsioon), sest ägenemine ei pruugi esialgu tekitada vaevusi, mistõttu patsient ei pöördu ise õigel ajal arsti poole ja ravi võib hilineda.

description: The contribution of D waves to physical observables for neutral pion photoproduction in the near threshold region is studied. Heavy Baryon Chiral Perturbation Theory to one loop, and up to ${\cal O}(q^4)$, is used to account for the S and P waves, while D waves are added in an almost model-independent way using standard Born terms and vector mesons. It is found that the inclusion of D waves is necessary to extract the $E_{0+}$ multipole reliably from present and forthcoming data and to assess the low-energy constants of Chiral Perturbation Theory. Arguments are presented demonstrating that F-wave contributions are negligible in the near-threshold region.

description: Rare earth based intermetallics, SmScGe and NdScGe, are shown to exhibit near zero net magnetization with substitutions of 6 to 9 atomic percent of Nd and 25 atomic percent of Gd, respectively. The notion of magnetic compensation in them is also elucidated by the crossover of zero magnetization axis at low magnetic fields (less than 103 Oe) and field-induced reversal in the orientation of the magnetic moments of the dissimilar rare earth ions at higher magnetic fields. These magnetically ordered materials with no net magnetization and appreciable conduction electron polarization display an attribute of an exchange bias field, which can be tuned. The attractively high magnetic ordering temperatures of about 270 K, underscore the importance of these materials for potential applications in spintronics.

description: Krooniline neeruhaigus (KNH) on üleilmne tervishoiuprobleem, sest KNH esineb tänapäeval sagedasti ja ravikulud on väga suured. KNH on n-ö varjatud ja vaikne haigus ning võib kulgeda märkamatult, sest seda haigust haige sageli ei tunne. Selline haiguse kulg on ka KNH aladiagnoosimise ja alaravimise põhjuseks. Suurtes rahvastiku-uuringutes on kindlaks tehtud, et erinevates staadiumides krooniline neerukahjustus võib olla ligikaudu igal kümnendal inimesel (1, 2).

description: Alzheimeri tõbi (AT) on levinuim dementsuse põhjus. Eestis on AT ravimitena praegu kasutusel atsetüülkoliinesteraasi inhibiitorid ja NMDA-retseptori antagonistid. AT patohistoloogiliste muutuste nurgakivi, amüloid β peptiidide kuhjumine, on ilmselt nii oksüdatiivse kahjustuse põhjus kui ka tagajärg. Antioksüdantsetel preparaatidel – α-tokoferool, Ginkgo biloba ekstrakt, lipoehape, melatoniin jt – on in vitro ja loommudelitel teostatud katsed näidanud küll nende tõhusust, kuid tõenduspõhise ravina soovitamiseks jääb see siiani tehtu alusel siiski väheseks. Õigustatud on edasised uuringud inimestel, v.a E-vitamiini puhul, mille kasutamise efektiivsus ja pikaajaline ohutus AT puhul on praegustele andmetele toetudes küsitav.

description: Background: Evidence that higher sedentary time is associated with higher risk for cardiovascular disease (CVD) is based mainly on self-reported measures. Few studies have examined whether patterns of sedentary time are associated with higher risk for CVD. Methods: Women from the OPACH Study (Objective Physical Activity and Cardiovascular Health; n=5638, aged 63-97 years, mean age 79±7 years) with no history of myocardial infarction or stroke wore accelerometers for 4 to 7 days and were followed up for up to 4.9 years for CVD events. Average daily sedentary time and mean sedentary bout duration were the exposures of interest. Cox regression models were used to estimate hazard ratios (HRs) and 95% CIs for CVD using models adjusted for covariates and subsequently adjusted for potential mediators (body mass index, diabetes mellitus, hypertension, and CVD risk biomarkers [fasting glucose, high-density lipoprotein, triglycerides, and systolic blood pressure]). Restricted cubic spline regression characterized dose-response relationships. Results: There were 545 CVD events during 19 350 person-years. With adjustment for covariates, women in the highest (≈11 h/d or more) versus the lowest (≈9 h/d or less) quartile of sedentary time had higher risk for CVD (HR, 1.62; 95% CI, 1.21-2.17; P trend <0.001). Further adjustment for potential mediators attenuated but did not eliminate significance of these associations (P trend <0.05, each). Longer versus shorter mean sedentary bout duration was associated with higher risks for CVD (HR, 1.54; 95% CI, 1.27-2.02; P trend=0.003) after adjustment for covariates. Additional adjustment for CVD risk biomarkers attenuated associations, resulting in a quartile 4 versus quartile 1 HR of 1.36 (95% CI, 1.01-1.83; P trend=0.10). Dose-response associations of sedentary time and bout duration with CVD were linear (P nonlinear >0.05, each). Women jointly classified as having both high sedentary time and long bout durations had significantly higher risk for CVD (HR, 1.34; 95% CI, 1.08-1.65) than women with low sedentary time and short bout duration. All analyses were repeated for incident coronary heart disease (myocardial infarction or CVD death), and associations were similar, with notably stronger HRs. Conclusions: Both high sedentary time and long mean bout durations were associated in a dose-response manner with increased CVD risk in older women, which suggests that efforts to reduce CVD burden might benefit from addressing either or both components of sedentary behavior.

description: Eesti Perearstide Seltsi viimaste aastate prioriteetseks tegevuseks on olnud erialase arengu stimuleerimine rõhuasetusega erialase pädevuse hindamisel, perearstipraksiste kvaliteedi arendamisel ja hindamisel ning kvaliteetse töö stimuleerimisel. Perearstide väljaõpe Eestis vastab kõikidele ELi nõuetele ning kõigil esmatasandil töötavatel perearstidel on perearsti kvalifi katsioon ehk nad on sertifi tseeritud perearstidena. Perearstide selts on loonud internetipõhise täienduskeskkonna Svoog, mis võimaldab kõigil keskkonnas registreerunud perearstidel jälgida konverentse ja loenguid, mida selts korraldab, ka interneti vahendusel; esitada küsimusi ja vastata küsimustele ning luua oma täienduspunktikonto. Valmimas on perearstipraksiste kvaliteedi käsiraamat.
Alates 2006. aastast on perearstide tasustamise ühe komponendina ette nähtud lisatasud ennetustegevuse, krooniliste haigustega patsientide parema jälgimise ning laiahaardelisema tegevuse stimuleerimiseks. Initsiatiiv selliseks tegevuseks on tulnud perearstide seltsilt, projekti on ette valmistatud alates 2001. aastast ning süsteemi täiustatakse pidevalt ka edaspidi koostöös perearstide seltsi ning haigekassaga.

description: We present a way to organize a constructive development of the theory of Banach algebras, inspired by works of Cohen, de Bruijn and Bishop. We illustrate this by giving elementary proofs of Wiener's result on the inverse of Fourier series and Wiener's Tauberian Theorem, in a sequel to this paper we show how this can be used in a localic, or point-free, description of the spectrum of a Banach algebra.

description: Artiklis antakse ülevaade salutogeneesi kontseptsioonist ja selle tõenduspõhisest rakendusvõimalusest rahvastiku tervise arendusel. Tutvustatakse salutogeneetilist lähenemist tervise kontseptsioonile ning selle erinevusi patogeneesi mõistest ja biomeditsiinilisest lähenemisest. Rahvatervise arenduse protsessides kasutab noor teadus salutoloogia erinevate teadusvaldkondade teooriaid, mudeleid ja fi losoofi at – alates positivistlikust paradigmast kuni konstruktivistliku paradigmani. Salutogeneetilised protsessid võtavad arvesse tausta, milles indiviid või grupp paikneb, ning püüavad saavutada muutusi koherentsusetunnetuses, st võimelisuses mõista olukorda, tunnetada seda tähendusrikkana ja suurendada probleemilahenduse suutlikkust. Koherentsusetunnetuse kujundamist gruppides/kogukonnas on võimalik tervist edendavatel eesmärkidel võimestumise strateegiatega planeeritult arendada.

Subjects: tiasiiddiureetikumid, lingudiureetikumid, kaaliumi säästvad diureetikumid

description: Diureetikume on hüpertensiooni ravis kasutatud juba pikka aega. Diureetikumide toimemehhanism põhineb peamiselt organismi vedelikumahu vähendamisel. Hüpertensiooni ravis kasutatakse kolme tüüpi diureetikume: tiasiidid, lingudiureetikumid ja kaaliumi säästvad diureetikumid. Sagedamini leiavad kasutamist tiasiidid, seda tänu nende täiendavale vasodilatoorsele efektile. Sagedasemateks kõrvaltoimeteks on hüponatreemia ja hüpokaleemia. Kaaliumi säästvatel diureetikumidel on kõrvaltoimeks hüperkaleemia, mis on oluline just halvenenud neerufunktsiooniga patsientidel. Kuigi teised ravimirühmad (AKE inhibiitorid, Ca-kanali antagonistid jm) on diureetikumid juhtpositsioonilt tõrjunud, on neil endiselt arvestatav osa hüpertensiooni kombineeritud ravis.

description: Poliomüeliit on viirushaigus, mis võib põhjustada ka jäsemete lõtvu halvatusi, bulbaarparalüüsi ja hingamispuudulikkust. 19. sajandi 80. aastatel ja 20. sajandi esimesel poolel puhkesid poliomüeliidiepideemiad Euroopas ja USAs. Hingamispuudulikkuse raviks konstrueeriti 1927. aastal esimene respiraator – nn raudne kops, mis võimaldas pikaajaliselt ravida hingamispuudulikkusega haigeid. Bulbaarparalüüsi korral hakati laialdaselt kasutama trahheostoomiat. Oluliselt paranesid hingamispuudulikkusega haigete ravi võimalused vahelduva positiivrõhuga hingamisaparaatide kasutuselevõtuga intratrahheaalseks ventilatsiooniks 1948. aastal ja mahuprintsiibil töötava Engströmi respiraatori rakendamisega. 1953. aastal avati Kopenhaagenis maailma esimene intensiivraviosakond. Massilise vaktsineerimise ja poliomüeliidi likvideerimise järel hakati saadud kogemusi rakendama kõikide kriitilises seisundis haigete ravis.

description: Measured values of the differential cross sections for pion-nucleon charge exchange, pi- p --> pi0 n, are presented for pi- momenta of 103, 112, 120, 130, 139, 152, and 178 MeV/c. Complete angular distributions were obtained by using the Crystal Ball detector at the Alternating Gradient Synchrotron at Brookhaven National Laboratory. Statistical uncertainties of the differential cross sections vary from 3% to 6% in the backward angle region, and from 6% to about 20% in the forward region with the exception of the two most forward angles. The systematic uncertainties are estimated to be about 3% for all momenta.
