Extending locally truncated geometries
Given a set of types I. a type 0 is an element of I, a subset J of I containing 0, and a diagram I(0) over I{0}. a geometry Gamma over the set of types J is said to be locally truncated of I(0)-type if the J{0}-residues of Gamma are truncations of geometries or chamber systems belonging to I(0). We give a sufficent condition for such a geometry to be the J-truncation of a chamber system over the set of types I with all I{0}-residues belonging to I(0). Then we apply our result to some special cases. We exploit it to classify flag-transitive c(n),c*-geometries of rank n + 2 greater than or equal to 4 and c(n),c*-geometries of order 2. We give a new proof of a theorem of Ronan on C(n),L-geometries and we construct chamber systems for a number of sporadic groups in which certain well known geometries are involved as truncations or residues.

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Effects of probiotic VSL#3 on glomerular filtration rate in dogs affected by chronic kidney disease: a pilot study
The aim of this study was to evaluate the effects of probiotic VSL#3 on glomerular filtration rate (GFR) in dogs affected by chronic kidney disease (CKD). The treatment group (n = 30) received prescription renal diet and probiotic VSL#3 (112 to 225 × 109 lyophilized bacteria per 10 kg body weight, PO, q24h for 2 months); the control group (n = 30) received prescription renal diet and standard therapy. All dogs underwent GFR measurement at the beginning of the study (T0) and were re-evaluated by GFR measurement after 2 months (T1). The GFR was significantly higher (P = 0.0001) in the treatment group compared to the control group at T1. In the treatment group, the GFR was significantly higher (P = 0.0008) at T1 compared to T0. In the control group, the GFR was significantly lower (P = 0.001) at T1 compared to T0. VSL#3 supplementation seemed to be efficient in reducing deterioration of GFR over time in dogs affected by CKD
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
THE SEQUENTIAL ORGAN FAILURE ASSESSMENT (SOFA) SCORE IN PREDICTING MORTALITY IN CRITICAL DOGS
Introduction: The Sequential Organ Failure Assessment (SOFA) score is an organ dysfunction scoring system used to assess critically ill patients.
Objective: To evaluate the correlation between the SOFA scores at the time of arrival and with outcome in critical patients in a veterinary ICU.
Methods: 689 clinical records of dogs, aged more than 1 year, red or yellow emergency code, were examined for the applicability of the SOFA score. Inclusion criteria were related to the presence of data required for the applicability of the SOFA score. Animals were divided in survival (S) and non-survival (NS) and data were analysed with a Mann–Whitney test. Patients were than divided in two subgroups: adult (1 to 8 years) and old (more than 8 years). A ROC test was performed to evaluate the sensitivity and specificity and the Youden’s index was calculated to find the best cut-off. P- values < 0.05 were considered significant.
Results: 112 records met all the inclusion criteria. The median (range) SOFA score for patients that survived was 2 (0–9) which was significantly lower than non-survival 5.5 (0–14). The median (range) SOFA score in the NS was 6.5 (0-14) and 5 (0–9) for adult and old respectively. The best cut-off score was 5.5 with a sensitivity of 56.6% and a specificity of 92.8%; all the scores > 9.5 resulted in a specificity of 100%.
Discussion: This study revealed a good predictive capability of the SOFA score in the ICU setting. A cut-off score of 5.5 produced a non-favorable outcome and scores over 9.5 were strictly connected to death. SOFA scores lower than 3 were associated with a good outcome. Old dogs had negative outcome with lower scores in comparison to adult dogs.
Conclusions: The SOFA scoring system resulted a useful tool to predict the outcome of critical dogs
RESPIRATORY EMERGENCIES IN DOGS: EVALUATION OF ARTERIAL BLOOD GAS AND RADIOGRAPHIC FINDINGS
Objective: To evaluate arterial blood gas (pH, PaO2, PCO2, SO2 P/F ratio, P[A-a]O2 gradient and HCO3-) and pulmonary radiographs in dogs presented in emergency setting with respiratory distress.
Materials and Methods: Arterial blood was obtained from the dorsal pedal artery at room air (FiO2 21%), were analyzed (ABL 700 seires, Radiometer-Copenhagen). A chest radiography was performed for each patient using a digital radiological equipment (Multimage, Cosmovet). Radiographs were evaluated for presence of 4 distinct pulmonary patterns: normal, alveolar, interstitial and mixed pattern. Animals were divided in 2 groups according to outcome: survivor (S) and not survivor (NS). Normal distribution was assessed using D’Agostino-Pearson test. T student test and Mann Whitney were used to compare pH, PaCO2, PaO2, P[A−a]O2 gradient, PaO2/FiO2, HCO3- and SO2 in (S) versus (NS) respectively. ANOVA one-way was used to compare radiographic pattern with PaO2/FiO2 and P[A−a]O2 gradient values.
Results: thirty-nine dogs were enrolled. Nine out of 39 (23%) did not survive (1 euthanized), 30/39 (77%) survived. Incidence of a PaO2/FiO2 <200mmHg was 13%, while a PaO2/FiO2 between 200-300 mmHg was found in 10/39 (25.6%) of subjects. A P[A-a]O2 gradient >20 mmHg was found in 30/39 (77%) dogs. In (S) group pH resulted 7.39±0.04, PaO2 77.2±18 mmHg, PCO2 33±5.7 mmHg, SO2 97.5% (66-101,8%), PaO2/FiO2 368±85 mmHg, P[A-a]O2 gradient 31±17 mmHg, HCO3- 19.3±3 mEq/L. In (NS) group pH resulted 7.33±0.1, PaO2 51±17 mmHg, PCO2 31.2±7 mmHg, SO2 74% (46.5-100,6%), PaO2/FiO2 242.5±84 mmHg, P[A-a]O2 gradient 59.7±22,4 mmHg, HCO3- 16.5±4.7 mEq/L. Alveolar pattern was identified in 9/39 (23.8%) dogs, interstitial pattern in 6/39 (15.3%), mixed pattern in 16/39 (41%), normal pattern in 3/39 (7.6%). In 5/39 was identified pleural effusion and pneumothorax. The mortality rate of alveolar pattern group (44%) was greater than other pattern groups. The Mann-Whitney test revealed a significant difference for pH, PaO2, SO2, PaO2/FiO2, P[A-a]O2 gradient and bicarbonate between (S) and (NS) (p<0.05). No statistically significant difference was found for radiographic pulmonary patterns with PaO2/FiO2 (p=0.5) and P[A−a]O2 gradient values (p=0.4).
Conclusion: animals with respiratory distress in the emergency setting are at higher risk of death when alveolar pattern and PaO2/FiO2 lower than 200 mmHg are present
