Higher Order mz-elements in Coherent Quantales
No full textThe mz-elements of a coherent quantale have recently been defined by the author as an abstraction of the mz-ideals of a unital commutative ring.
Having as its starting point the Dube and Ighedo recent paper on higher order ideals in ring theory, this paper deals with the higher order mz-elements of a coherent quantale A. For each natural number n we define the mz^n-elements of A, so we obtain an ascending sequence that covers the set of all higher order mz-elements. We obtain a lot of properties of this sequence. In particular, the stationarity of the sequence is studied. Another category of results investigates how the coherent quantale morphisms preserve such properties
Impact of using different predictive equations on the prevalence of chronic byssinosis in textile workers in Pakistan
No full textOBJECTIVE: Byssinosis remains a significant problem among textile workers in low/middle-income countries. Here we share our experience of using different prediction equations for assessing 'chronic' byssinosis according to the standard WHO classification using measurements of forced expiratory volume in 1 s (FEV1). METHODS: We enrolled 1910 workers in a randomised controlled trial of an intervention to improve the health of textile workers in Pakistan. We included in analyses the 1724 (90%) men who performed pre-bronchodilator spirometry tests of acceptable quality. We compared four different equations for deriving lung function percentage predicted values among those with symptoms-based byssinosis: the third US National Health and Nutrition Examination Survey (NHANES-III, with 'North Indian and Pakistani' conversion factor); the Global Lung Function Initiative (GLI, 'other or mixed ethnicities'); a recent equation derived from survey of a western Indian population; and one based on an older and smaller survey of Karachi residents. RESULTS: 58 men (3.4%) had symptoms-based byssinosis according to WHO criteria. Of these, the proportions with a reduced FEV1 (<80% predicted) identified using NHANES and GLI; Indian and Pakistani reference equations were 40%, 41%, 14% and 12%, respectively. Much of this variation was eliminated when we substituted FEV1/forced vital capacity (FVC) ratio
A spectroscopic study of the bipolar planetary nebula Mz 3
No full textWe have obtained a medium-resolution, deep optical long-slit spectrum of the bipolar planetary nebula Mz 3. The spectrum covers the wavelength range 3420-7400 Å. Over 200 emission lines have been detected, many of them permitted and forbidden transitions from Fe +, Fe 2+ and Fe 3+ and other iron-group elements. The spectra have been used to determine nebular thermal and density structures and elemental abundances. The very rich and prominent [Fe III] emission lines observed in the optical spectrum of Mz 3 are found to originate exclusively from an unresolved emission region centred on the central star. The relative intensities of [Fe III] lines arising from the same upper level are in good agreement with the theoretical predictions. The [Fe III] lines detected in Mz 3, arising from levels of different excitation energies and critical densities, provide powerful diagnostic tools to probe the physical conditions in the central emitting region. We find that all the observed [Fe III] diagnostic line ratios consistently yield an electron temperature of T e = 11 000 K and a density of log N e(cm -3) = 6.5. The latter value is close to the densities where the ratios of these [Fe III] diagnostic lines are most sensitive to density variations, suggesting that the density in the central emission core could be even higher. In contrast, all the other standard nebular density- and temperature-diagnostic line ratios, all of lower critical densities than the [Fe III] lines and therefore only useful at densities ≤ 10 6 cm -3, yield consistently lower electron densities, with the resultant values correlating with their critical densities. This indicates that the central dense emission core has a highly stratified density structure such that forbidden lines of relatively low critical densities are collisionally suppressed in high-density regions. Given the highly stratified thermal and density structures of the core emission region, no reliable elemental abundances can be determined for this region, except possibly for iron, for which we find an abundance of approximately half the solar value. In contrast to the dense central core, emission from the extended bipolar lobes of Mz 3 are well represented by a mean electron temperature of 6800 K and density of 5200 cm -3. The elemental abundances derived for this region, on a logarithmic scale where H = 12, are He = 10.93, C = 8.41, N = 8.37, O = 8.50, Ne = 7.64, S = 7.15, Cl = 5.28 and Ar = 7.14. In all cases, the abundances are close to the average values deduced for Galactic planetary nebulae. In particular, there is no evidence of He enrichment, as claimed in previous studies. The newly derived heavy-element abundances are significantly higher than those published in the literature. In those earlier studies, as a result of the contamination of emission from the dense central core, the average electron temperature in Mz 3 was significantly overestimated, resulting in grossly underestimated heavy-element abundances. However, Mz 3 does seem to have a relatively high N/O abundance ratio, in line with the result derived from the ISO observations of the far-infrared fine-structure lines.link_to_OA_fulltex
The arithmetic mean theorem of eshelby tensor for a rotational symmetrical inclusion
No full textIn 1997, H. Nozaki and M. Taya found numerically that for any regular polygonal inclusion except for a square, both the Eshelby tensor at the center and the average Eshelby tensor over the inclusion domain are equal to the Eshelby tensor for a circular inclusion and independent of the orientation of the inclusion. Then in 2001, these remarkable properties were mathematically justified by Kawashita and Nozaki. In this paper, a more radical property is presented for a rotational symmetrical inclusion: For any N-fold (N is an integer greater than 2 and unequal to 4) rotational symmetrical inclusion, the arithmetic mean of the Eshelby tensors at N rotational symmetrical points in the inclusion is the same as the Eshelby tensor for a circular inclusion and independent of the orientation of the inclusion. It follows that the Eshelby tensor at the center and the average Eshelby tensor over the rotational symmetrical inclusion domain are identical to the Eshelby tensor for a circular inclusion and independent of the orientation of the inclusion as well. This paper shows that although the Eshelby property does not hold for non-ellipsoidal inclusions, the Eshelby tensor for a rotational symmetrical inclusion satisfies the arithmetic mean property.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000229972600002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Engineering, MultidisciplinaryMaterials Science, MultidisciplinaryMechanicsSCI(E)EI22ARTICLE113-237

Clinical profiles of chronic renal failure patients at referral to nephrologist
No full textThe quality of care of patients with chronic renal failure (CRF) in their pre-dialysis state is known to have a significant impact on the mortality and morbidity of dialysis patients. We evaluated 78 patients with chronic renal disease who were referred to our center for Follow-up of nephrologists between June 2002 and July 2003. We studied the etiology of the disease and the different biological parameters at the time of first nephrology clinic visit. The mean age of the patients was above 52 years. Diabetes mellitus was the leading cause of CRF found in 28% of patients, followed by hypertension in 24% cases. Seventy percent of the patients were in a state of moderate and severe renal failure at referral with mean blood urea nitrogen (BUN) of 22 +/- 13 mmol/L, serum creatinine of 390 +/- 180 micromol/L and creatinine clearance of 16.8 +/- 14.2 ml/min. Our study suggests that the referring physicians should be more aware of the timing of referral of patients with CRF to nephrologists so that optimum pre-dialysis care can be ensured to improve the quality of life and better outcome of CRF patients
Exegetical and theological analysis of Leviticus 26:3-13
No full textV diplomskem seminarskem delu z naslovom Eksegetska in teološka analiza blagoslovov v 3 Mz 26,3-13 avtor predstavlja blagoslove v 3 Mz 26,3-13. Avtor delo deli v štiri poglavja. V prvem poglavju skuša razložiti nekatere bistvene značilnosti odlomka, pri čemer ugotovi, da je odlomek del Božjega govora po svetostni postavi, odlomek pa časovno umesti v obdobje po izgnanstvu. V drugem poglavju odlomek eksegetsko razloži in pri tem ugotavlja primernost delitve 3 Mz 26,4-12 v štiri dele. V tretjem poglavju s pomočjo predstavitve značilnosti vzporednega odlomka 5 Mz 28,1-14 osvetljuje nekatere bistvene značilnosti 3 Mz 26,3-13. Avtor ob tem poudarja, da se oba odlomka o blagoslovih nahajata po postavi: 3 Mz 26 po svetostni postavi, 5 Mz 28 pa po devteronomični. Izpostavi dvoje: da sta govornika v odlomkih različna ter da je v prvem odlomku izraelsko ljudstvo naslovljeno v drugi osebi množine, v drugem pa v drugi osebi ednine. Avtor ob tem poudari, da je za 5 Mz značilna uporaba merizma, s katero se želi poudariti blagoslovljenost Izraela tako v mestu kot na polju, torej povsod. V zadnjem poglavju avtor išče vzporednice 3 Mz 26,3-13 z Novo zavezo in današnjim časom. Ob povezavi z Novo zavezo izpostavi razliko in razmerje med blagoslovi in blagri ter izpostavi odlomka 2 Kor 6,16 in Raz 21,3, kjer je zaslediti citata iz 3 Mz 26. Ob povezavi z današnjim dnem ugotavlja, da je blagoslova deležno vse človeštvo.The aim of the present diploma thesis with the title Exegetical and theological analysis of Leviticus 26:3-13 is to present the blessings in the verse Lev 26:3-13. The author has divided the contents of the thesis into four chapters. The first chapter is an attempt to explain some key features of the verse, where the author concludes that it represents part of God’s speech that is given after the end of the Holiness Code after the Exile Israel. In the second chapter, the author attempts to explain the verse exegetically and discusses the relevance of the division of Lev 26:4-12 into four parts. With the help of the explanation of the features of the parallel verse Deut 28:1-14, the author aims to illuminate some key features of Lev 26:3-13. The author concludes that both chapters about blessings are included at the end of sections about two codes: Lev 26 comes at the end of the Holiness Code and Deut 28 at the end of the Deuteronomic Code. The author also concludes that the speakers in both verses are not the same, and notes that in Lev 26:3-13 the Israel is addressed in the second person plural, whereas in Deut 28:1-14 they are addressed as the second person singular. The author points to the use of merism in Deut 28, which emphasises the blessing of Israel in both the city and in the field, and thus everywhere. In the last chapter, the author searches for parallels between Lev 26:3-13, the New Testament and the present time. In the New Testament the difference and relation between the blessings and beatitudes are highlighted, while the author notes 2 Cor 6:16 and Rev 21:3 as passages where references to Lev 26 can be found. In connection with the present day, the author establishes that the whole of mankind is now blessed
The double level calculation of oxygen related donor states in Si and SiO2
No full textA calculation of the levels related to oxygen donors in Si and SiO2 has been performed based on a helium-like model. These calculations agree well with the experimental data while the energies of these levels are in the ratio of about 2:1 and the effective radii of these levels are in the ratio of about 2:1.
