Die predikant as teiken – profiel van iemand wat emosionele wonde toedien
S.F. Kruger
In die Skriflig , 2004, DOI: 10.4102/ids.v38i3.439
Abstract: A minister as target – profile of a person inflicting emotional wounds This article focuses on the personality of someone who intentionally wounds a minister of the Word. The typical profile of someone who wounds emotionally, and the behavioural process that usually characterises his acts are highlighted. At the meta-theoretical level the interpersonal style of a wounder is examined by applying viewpoints of Interpersonal Theory – a subsection of Personality Psychology. The specific behavioural style of a wounder comprises characteristics such as being dominating, competitive, distrusting, cold and hostile. The basis-theoretical survey conducted in this article focuses on the relationship between Paul and the Corinthian church with specific reference to the underlying relational tension. This survey reveals that the effective functioning of a congregation as a community of faith and love is of utmost importance in the identification of the personality type of the person who intentionally wounds a minister of the Word. In conclusion an analysis for understanding, as well as guidelines for coping with the whole situation is proposed. The reaction of a minister and a congregation’s understanding of the nature of the wounding process are outlined as being of specific importance.
Small flow rate can supply inwardly migrating shortest-period planets
Taylor S.F.
EPJ Web of Conferences , 2013, DOI: 10.1051/epjconf/20134702003
Abstract: The number of exoplanets found with periods as short as one day and less was surprising given how fast these planets had been expected to migrate into the star due to the tides raised on the star by planets at such close distances. It has been seen as improbable that we would find planets in such a small final fraction of their lives [1]. The favored solution has been that the tidal dissipation is much weaker than expected, which would mean that the final infall would be a larger fraction of the planets’ life. We find no reason, however, to exclude the explanation that a small number of planets are continuously sent migrating inwards such that these planets indeed are in the last fraction of their lives. Following the observation that the distribution of medium planets disfavors tidal dissipation being significantly weaker than has been found from observations of binary stars [2], we now show that the numbers of planets in such a “flow” of excess planets migrating inwards is low enough that even depletion of the three-day pileup is a plausible source. Then the shortest period occurrence distribution would be shaped by planets continuously being sent into the star, which may explain the depletion of the pileup in the Kepler field relative to the solar neighborhood [3]. Because Kepler observes above the galactic plan, [3] suggested the Kepler field may include an older population of stars. The tidal dissipation strength in stars due to giant planets may be not greatly weaker than it is in binary stars.
Diversity and stability of fishes (Teleostei) in a temporary river of the Brazilian semiarid region
Medeiros, Elvio S.F.;Maltchik, Leonardo;
Iheringia. Série Zoologia , 2001, DOI: 10.1590/S0073-47212001000100016
Abstract: the effects of hydrological disturbances by flooding and drought on the diversity and stability in a temporary river fish community in the brazilian semiarid region were analyzed over the 1996 hydrological cycle. twelve collections of fishes were made during the wet and dry phases, and 789 individuals of 16 species were collected. diversity was measured using simpson's index (s) and community stability was analyzed by the variation in abundance using kendall's w concordance test. fish diversity in the taperoá river was subjected to hydrological disturbances by flooding and drought. during the wet phase the diversity was higher (s = 0.855) than during the dry phase (s = 0.771). the community was considered stable during the whole annual hydrological cycle (w = 0.418 p < 0.001), but a higher stability in the community was found during the dry phase. during the dry phase the number of dominant species was smaller than during the wet phase.
Diferenciación morfométrica del húmero y fémur de las especies de Paedotherium (Mammalia, Notoungulata) del Plioceno y Pleistoceno temprano
Elissamburu,A.; Vizcaíno,S.F.;
Ameghiniana , 2005,
Abstract: the genus paedotherium includes small rodent-like ungulates that are distinguished by characters of the skull and teeth. morphofunctional differences in the appendicular skeleton of p. bonaerense ameghino and p. typicum ameghino (pliocene- early pleistocene) suggest that appendicular characters can be used in specific identification. in this contribution, morphometric differences between the humerus and femur are analysed. five humeral and six femoral measurements are taken from 29 specimens. they include functional length (lh), deltoid length (ldh), transverse and anteroposterior diameter (dth, daph) and epicondilar diameter (deh) for the humerus, and functional length (lf), proximal length to the third trochanter (lttf) and to the lesser tuberosity (ltmf), transverse and anteroposterior diameter (dtf, dapf) and epicondilar diameter (def) for the femur. data are analysed by comparison of means, principal components analysis (pca), discriminant analysis (da) and correlation with body mass. paedotherium bonaerense and p. typicum show differences in deh, with higher values for the former, and in lf and lttf, with higher values for the latter. the humerus is more important than the femur in differentiating between the species. as shown by the multivariate analysis, the association between deh and lh provides the best discriminator between the species. in the femur, lf and lttf are associated with the variation of dtf, def and body mass. da shows the importance of the humerus for discriminating between the species, and that the femur is a poor discriminator, probably due to the influence of body mass on the linear data.
Geological features and the Paleoproterozoic collision of four Archean crustal segments of the S?o Francisco Craton, Bahia, Brazil: a synthesis

Anais da Academia Brasileira de Ciências , 2002, DOI: 10.1590/S0001-37652002000200009
Abstract: recent geological, geochronological and isotopic research has identified four important archean crustal segments in the basement of the s?o francisco craton in the state of bahia. the oldest gavi?o block occurs in the wsw part, composed essentially of granitic, granodioritic and migmatitic rocks. it includes remnants of ttg suites, considered to represent the oldest rocks in the south american continent (~ 3,4ga) and associated archean greenstone belt sequences. the youngest segment, termed the itabuna-salvador-cura?á belt is exposed along the atlantic coast, from the se part of bahia up to salvador and then along a ne trend. it is mainly composed of tonalite/trondhjemites, but also includes stripes of intercalated metasediments and ocean-floor/back-arc gabbros and basalts. the jequié block, the third segment, is exposed in the se-ssw area, being characterized by archean granulitic migmatites with supracrustal inclusions and several charnockitic intrusions. the serrinha block (fourth segment) occurs to the ne, composed of orthogneisses and migmatites, which represent the basement of paleoproterozoic greenstone belts sequences. during the paleoproterozoic transamazonian orogeny, these four crustal segments collided, resulting in the formation of an important mountain belt. geochronological constrains indicate that the regional metamorphism resulting from crustal thickening associated with the collision process took place around 2.0 ga.
ABO incompatibility hemolytic disease following exchange transfusion 96 newborn
Khatami S.F,Behjati SH.
Tehran University Medical Journal , 2007,
Abstract: Background: ABO incompatibility hemolytic disease of the newborn is a common cause of clinical jaundice and causes two-thirds of the hemolytic disease in newborns. This study was undertaken to determine the frequency of ABO incompatibility hemolytic disease and its complications in newborns undergoing exchange transfusion.Methods: This prospective and descriptive study was performed in jaundiced newborn infants during a three-year period. Inclusion criteria were: maternal blood type O, newborn blood type A or B, rising indirect hyperbilirubinemia in the first two days of life, positive immunohematologic test for newborns and exchange transfusion. Exclusion criteria were: incomplete information, other accompanying diseases that induce hyperbilirubinemia. All newborn infants received phototherapy before and after exchange transfusion. We did not use intravenous immunoglobulin, hemoxygenase inhibitor drugs and blood products before exchange transfusion.Results: Double-volume exchange transfusion via umbilical cord catheter was performed in 96 patients, 19 (20%) of whom suffered from ABO incompatibility. Of these 19 newborns, two-thirds (13) were preterm infants. The minimum level of serum bilirubin was 10 mg/dl and the maximum serum bilirubin level was 35 mg/dl. In six patients (32%) serum bilirubin levels were >25mg/dl. The most common blood group was type A for newborns. Immunohematologic tests were positive in 84% of the mothers. ABO incompatibility hemolytic disease was the fourth and second most common reasons for blood exchange transfusion in preterm and term infants, respectively. Laboratory complications were more common than clinical complications. The etiology of 48% of the alloimmunization and 42% of the hemolytic disease in these newborns was ABO incompatibility.Conclusions: Mothers with blood group O and newborns with blood group A or B with positive immunohematologic tests in first hours of life are at high risk for hemolytic disease. Therefore, in this high-risk group, further therapy including prophylactic phototherapy, intravenous immunoglobulin and intramuscular protoporphyrins are necessary to prevent severe jaundice and decrease the need for exchange transfusion.
Use of stochastic optimization techniques for damage detection in complex nonlinear systems
Jafarkhani R.,Masri S.F.
MATEC Web of Conferences , 2012, DOI: 10.1051/matecconf/20120103005
Abstract: In this study, the performance of stochastic optimization techniques in the finite element model updating approach was investigated for damage detection in a quarter-scale two-span reinforced concrete bridge system which was tested experimentally at the University of Nevada, Reno. The damage sequence in the structure was induced by a range of progressively increasing excitations in the transverse direction of the specimen. Intermediate non-destructive white noise excitations and response measurements were used for system identification and damage detection purposes. It is shown that, when evaluated together with the strain gauge measurements and visual inspection results, the applied finite element model updating algorithm on this complex nonlinear system could accurately detect, localize, and quantify the damage in the tested bridge columns throughout the different phases of the experiment.
PALAEOMAGNETIC INVESTIGATIONS OF ASIRGARH VOLCANICS, BURHANPUR DISTRICT, MADHYA PRADESH, INDIA WITH SPECIAL REFERENCE TO MAGNETO-STRATIGRAPHIC CORRELATION
KHADRI , S.F.R
Indian Streams Research Journal , 2013,
Abstract: Preliminary palaeomagnetic studies were carried out on sixteen lava flows forming 500 meter thick pile of lava flows, exposed in Asirgarh hill ranges, northwestern part of Burhanpur district, Madhya Pradesh.(Lat: 21o15'–20o30'and Long:76o – 76o 15')(55C/3).During this study detailed flow mapping has been carried out with the help of eighteen field traverses, with collection of 220 oriented block rock samples. The palaeomagnetic results indicate the presence of N–R sequence with 'Normal' geomagnetic polarity shown by lower five flows (Flow I-V) and upper eleven flows (Flow VI-XIV) shows 'Reversed 'magnetic polarity. The palaeomagnetic results also indicates few irregular natural remnant directions initially improved by applying alternating field demagnetization(AFD) and step wise thermal demagnetization (TD) technique. The lower 'Normal' flows shows the mean direction of D=326o and I= -48. Whereas, upper 'Reversed' flow shows mean direction of D=154o and I= +56. During this study the complete lava pile exposed in this area has been divided in to two different formations. On the basis of these studies magneto stratigraphy and palaeomagnetic polarity of this area has been prepared.

Abstract: Recent geological, geochronological and isotopic research has identified four important Archean crustal segments in the basement of the S o Francisco Craton in the State of Bahia. The oldest Gavi o Block occurs in the WSW part, composed essentially of granitic, granodioritic and migmatitic rocks. It includes remnants of TTG suites, considered to represent the oldest rocks in the South American continent (~ 3,4Ga) and associated Archean greenstone belt sequences. The youngest segment, termed the Itabuna-Salvador-Cura á Belt is exposed along the Atlantic Coast, from the SE part of Bahia up to Salvador and then along a NE trend. It is mainly composed of tonalite/trondhjemites, but also includes stripes of intercalated metasediments and ocean-floor/back-arc gabbros and basalts. The Jequié Block, the third segment, is exposed in the SE-SSW area, being characterized by Archean granulitic migmatites with supracrustal inclusions and several charnockitic intrusions. The Serrinha Block (fourth segment) occurs to the NE, composed of orthogneisses and migmatites, which represent the basement of Paleoproterozoic greenstone belts sequences. During the Paleoproterozoic Transamazonian Orogeny, these four crustal segments collided, resulting in the formation of an important mountain belt. Geochronological constrains indicate that the regional metamorphism resulting from crustal thickening associated with the collision process took place around 2.0 Ga.

Online Brazilian Journal of Nursing , 2005,
Abstract: Treated as a study desenvolved with the objective of understanding the power relations in the heterosexual couple from the male perspective including his relation with the prevention of aids. Therefore ten men with heterosexual orientation, that have sexual-afective relations lasting, legally constituited or not- in co – habitation with a companion and whom at least has the same level of instruction, took part in the study. The proposition of Foucault about power relations and the constitution of the subjectivity form the bases of philosophical theory that support the qualitative study, which uses convergent-assistential-research-CAR- as a methodological reference.The datas were collected through group discussions, desenvolved between six meetings , in which diverse theme relacioned with sexuality and STD/aids were treated .The groups meetings initiate the health education that propel the convergence between the research and the preconcide assistant by CAR. Apart from this meetings datas were collected during two individual interviews realized in each one of the men which guide include themes related with living as a couple and the afective-sexual life of the man and the couple. The analysis of the data was done in accordance with the collective speech person-CSP, which profer organisation of speech from greater themes, that emerges group discussions and told individually in which they maintain strong connections with the question and with objectives of the study. This themes include what it is to be a man, the afective-sexual life of the couple, and the use of protection, and in each one of them, a CSP was organized aroud the different central ideas, in wich they complement one another. The discussion of CSP related to this theme facilitate the better understanding of problems in study and shows the evidence of the existence of different dynamics the circulation of power in the relations of the couple, in which has direct implications in the health education work for prevention of the STD/aids. The comprehension of this dynamics subsidize the proposition of a theorical reference in the use of health education – focal of nursing caring – for the prevention of STD/aids. In these reference, articulation of the idea of health promotions, health education, dialogue, heterosexual couple, health and taking care of yourself, the prepast relations thr power that it dissimulate as a social body.
