Characteristics of the Cfu‐S Population In Mice Carrying the SlJ Allele
Full text linkAbstract Abstract. A tentative characterization of haemopoietic stem cells with respect to their organ distribution, seeding fraction and colony formation in the spleen, radiosen‐sitivity and humoral regulation was attempted in mice heterozygous for the mutant allele SlJ and in their normal littermates. SlJ/+ mice were characterized by a deficient CFU‐s content of the blood and spleen and had slightly lower femoral CFU‐s numbers. This CFU‐s distribution could not be explained by differences in seeding efficiency ‘f’ between CFU‐s of SlJ/+ and +/+ origin in lethally irradiated recipients used in the CFU‐s assay. the seeding fraction of CFU‐s of +/+ origin did not differ in +/+ and SlJ/+ recipients. However, in irradiated SIJ/+ recipient mice a 30% decrease was observed in the number of the colonies derived from splenic and femoral CFU‐s of both +/+ and SlJ/+ origin. the serum level of SHSF (splenic haemopoiesis stimulating factor) was decreased in SlJ/+ mice, but significantly increased in Sl/Sld mice, as compared to their respective normal +/+ littermates. Endogenous colony formation in SlJ/+ spleens was deficient in comparison to that observed in +/+ spleens, and distinct sex differences were observed. However, mutant and normal CFU‐s from spleen and bone marrow had a similar survival following in‐vitro y irradiation. Femurs and spleens of both SlJ/+ and +/+ origin were implanted into both SlJ/+ and +/+ hosts. Six weeks later the SlJ/+ grafts contained less CFU‐s than the +/+ grafts. These data show that the splenic stroma of SlJ/+ mice is not defective in its capacity to lodge injected CFU‐s but is deficient in its ability to maintain CFU‐s under ‘steady‐state’ conditions and stimulate their colony formation in a ‘perturbed state’. Some of the characteristics of SlJ/+ mice segregate them from Sl/Sld mice, i.e. a deficient splenic CFU‐s content, normal seeding fractions ‘f’ of CFU‐s from spleen and bone marrow in the presence of an almost compensated anemia, and decreased serum levels of SHSF. the study of the SlJ trait may be a useful extension of the current Sl/Sld model for exploration of hereditary defects in haematopoietic stroma.

Regulation of haemopoietic stem‐cell proliferation in mice carrying the Slj allele
Full text linkWe investigated a haemopoietic stromal defect, in mice heterozygous for the Slj allele, during haemopoietic stress induced by treatment with bacterial lipopolysaccharides (LPS) or lethal total body irradiation (TBI) and bone‐marrow cell (BMC) reconstitution. Both treatments resulted in a comparable haemopoietic stem cell (CFU‐s) proliferation in Slj/+ and +/+ haemopoietic organs. There was no difference in committed haemopoietic progenitor cell (BFU‐e and CFU‐G/M) kinetics after TBI and +/+ bone‐marrow transplantation in Slj/+ and +/+ mice. the Slj/+ mice were deficient in their ability to support macroscopic spleen colony formation (65% of +/+ controls) as measured at 7 and 10 days after BMC transplantation. However, the Slj/+ spleen colonies contained the same number of BFU‐E and CFU‐G/M as colonies from +/+ spleens, while their CFU‐s content was increased. On day 10 post‐transplantation, the macroscopic ‘missing’ colonies could be detected at the microscopic level. These small colonies contained far fewer CFU‐s than the macroscopic detectable colonies. Analysis of CFU‐s proliferation‐inducing activities in control and post‐LPS sera revealed that Slj/+ mice are normal in their ability to produce and to respond to humoral stem‐cell regulators. We postulate that Slj/+ mice have a normal number of splenic stromal ‘niches’ for colony formation. However, 35% of these niches is defective in its proliferative support. Copyrigh
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Linear elastic fracture mechanics (LEFM)-based single lap joint (SLJ) mixed-mode analysis for aerospace structures}.
No full textThis paper investigates the study of crack propagation on single lap joint (SLJ) using cohesive zone modeling (CZM) for aerospace applications. To carry out the above task, linear elastic fracture mechanics (LEFM) approach using finite element methods was used to study the damage propagation in adhesively bonded joints. A traction–separation law was used to simulate the mode-II and mixed-mode-I+II interfacial fractures of adhesively bonded specimens loaded (quasi-static) in three-point bending and mixed-mode bending. An initial crack opening was introduced at the interfaces of the adherend/adhesive. The boundary conditions for SLJ have been set to carry out the interlaminar mode-II (shear mode) and mixed-mode fracture analysis by end notched flexure (ENF) and mixed-mode bending (MMB) methods. Optimized cohesive parameters from the literature survey were used for simulation of the tests, and same parameters have been validated to continue the research work focusing mainly on progressive delamination in SLJ. The total displacement of 10 mm was applied at free end, and as a result the reaction forces at fixed end steadily progressed up to 60% of applied displacement; further it has been observed the model starts failing by reduction in load versus displacement slope curve
Role of splenic stroma in the action of bacterial lipopolysaccharides on radiation mortality: a study in mice carrying the Slj allele
Full text linkAbstract. Slj/+ mice display a slight macrocytic anaemia due to a defect in their haemopoietic organ stroma. They have a deficient endogenous spleen colony (CFU‐end) formation following sublethal doses of gamma‐radiation compared with their normal +/+ littermates, which is likely to be due to the low pre‐irradiation CFU‐S content of the Slj/+ spleen. CFU‐S in these congenic mice do not differ in their sensitivity to gamma‐irradiation or stem cell‐activating factor. While injection of +/+ mice with 10 μg of lipopolysaccharide‐W (LPS) one day prior to irradiation led to a substantial increase in their survival, the survival of Slj/+ mice was only slightly increased. Irradiation induced a similar dose‐related reduction in the numbers of CFU‐S in the spleen and femora of LPS‐injected Slj/+ mice compared to similarly treated +/+ mice when measured directly after irradiation. At Day 9 after irradiation, injection of LPS led to a significantly higher CFU‐end formation and higher numbers of CFU‐S and nucleated cells in the Slj/+ spleens compared to LPS‐injected +/+ mice. No such differences in the radioprotective effect of LPS were observed in the +/+ and Slj/+ mice with respect to the splenic and femoral 59Fe‐incorporation and the femoral CFU‐S numbers at Day 9. These data strongly suggest a contribution by immigrating CFU‐S to the CFU‐S numbers and endogenous colony formation in at least the Slj/+ spleen after LPS injection and subsequent sublethal irradiation. The observations also imply that the splenic organ stroma may play a mediatory role in the radioprotective action of LPS. In addition, the data represent an extreme example of a lack of correlation between animal survival and haemopoietic parameters. Caution should be taken when applying endogenous colony counts as a means of screening potential anti‐radiation drugs. Copyrigh
PENGARUH FILLER SERBUK ALUMINUM PADA ADHESIF EPOKSI DAN SURFACE PATTERN TERHADAP KEKUATAN GESER SLJ ANTARA PLAT AL-5083/GFRP
Full text linkTujuan dari penelitian ini adalah untuk menyelidiki pengaruh kandungan serbuk aluminum pada epoksi dan surface pattern terhadap kekuatan geser single lap joint (SLJ) sambungan plat GFRP dan Al-5083. Bahan adhsif terbuat dari epoksi yang ditambahkan dengan serbuk alumninium (0%; 2,5%; 5%; 7,5%; 10%; dan 12,5% terhadap massa). Hasil terbaik dari variasi pertama dijadikan acuan untuk variasi kedua yang menggunakan lima jenis surface pattern (plain, 00, 900-cross, 450, dan 450-cross). Semua spesimen diuji dengan menggunakan standar ASTM D-1002. Hasil penelitian menunjukkan bahwa kenaikan jumlah kandungan serbuk aluminium akan menambah kekuatan geser dari sambungan SLJ. Kekuatan geser SLJ spesimen dengan 12,5% serbuk aluminium (6,92 MPa) mengalami kenaikan 110,3% dibandingkan spesimen tanpa kandungan serbuk aluminium (3,29 MPa). Kekuatan geser SLJ pada spesimen dengan 900 cross-type memiliki kekuatan yang paling tinggi (7,21 MPa) dibandingkan dengan spesimen lainnya. Jenis kegagalan yang terjadi pada spesimen dengan variasi kandungan 12,5% serbuk aluminium dikategorikan sebagai mixed failure yang terdiri dari tear fibre failure, adhesive failure, dan thin layer cohesive, sedangkan persentase kandungan lainnya memiliki jenis kegagalan adhesive failure. Semua spesimen dengan surface pattern menghasilkan mixed failure, kecuali pada 900 crosss-type yang mengalami fiber-tear failure
