title: Long bone fractures in Cerdocyon thous: macroscopic and microstructural evaluation

description: Abstract The aim of the present study was to perform the macroscopic and microstructural morphological classification of long bone fractures of Cerdocyon thous. Eighteen cadavers of the species were necropsied, and subjected to radiographic and microscopical evaluation when long bone fractures were detected. Among the 18 cadavers, eight (44%) had fractures equally distributed (33.33%) in the femur, humerus, or tibia. More frequently (61.54%), the fractures were simple and affected the diaphysis, and in smaller proportions (23.08%) reached the physeal line. In diaphyseal and metaphyseal fractures, microscopical evaluation revealed cortical bone tissue, with longitudinal osteons that contained longitudinal and intermediate collagen fibres and lamellae with a delamination aspect. On the other hand, in epiphyseal fractures, trabecular bone tissue was more frequently observed, consisting of trabeculae with disorganised collagen fibres and absence of osteons. In both cases low activity, osteocytes, and low coverage of osteoblasts on the bone surface were noted. It was concluded that the frequency of fractures in the long bones of C. thous was 44%, with females being more predisposed. The findings support the hypothesis that fractures in such animals are caused by being run over by automobiles. The present study contributes significantly in alerting clinicians and surgeons to the types of fractures that C. thous is more predisposed to, its places of greatest occurrence, and its microstructure. Thus, there is a need for joint actions aimed at reducing the number of cases of wild animals being run over by automobiles.

title: Dataset for the study "Changes in audio-spatial working memory abilities during childhood: The role of spatial and phonological development"

description: Working memory is a cognitive system devoted to storage and retrieval processing of information.<br> Numerous studies on the development of working memory have investigated the<br> processing of visuo-spatial and verbal non-spatialized information; however, little is known<br> regarding the refinement of acoustic spatial and memory abilities across development.<br> Here, we hypothesize that audio-spatial memory skills improve over development, due to<br> strengthening spatial and cognitive skills such as semantic elaboration. We asked children<br> aged 6 to 11 years old (n = 55) to pair spatialized animal calls with the corresponding animal<br> spoken name. Spatialized sounds were emitted from an audio-haptic device, haptically<br> explored by children with the dominant hand’s index finger. Children younger than 8<br> anchored their exploration strategy on previously discovered sounds instead of holding this<br> information in working memory and performed worse than older peers when asked to pair<br> the spoken word with the corresponding animal call. In line with our hypothesis, these findings<br> demonstrate that age-related improvements in spatial exploration and verbal coding<br> memorization strategies affect how children learn and memorize items belonging to a complex<br> acoustic spatial layout. Similar to vision, audio-spatial memory abilities strongly depend<br> on cognitive development in early years of life. Data in the file are divided into six sheets based on the age of the participants and the experimental condition, either call-call or call-name. Each sheet contains six columns: Participant ID, age and gender are the first three. The last three columns instead refer to the test parameters: the number of attempts, the audio-anchor and the score. In details, the number of attempts indicates the number of trials needed to pair the sounds. The audio-anchor provides a measurement of the exploration strategy. It accounts for how many consecutive attempts the child begins by touching the same speaker while the score takes into account the frequency of touches on the same speakers: the more the participant returns on the same stimulus location, the lower the score.

title: Ex vivo study of use of physiotherapy ultrasound in polymethylmethacrylate beads doped with methylene blue as an antibiotic carrier

description: Abstract Polymethylmethacrylate bone cement is a standard material used as antibiotic carrier in the orthopedic surgery. The ultrasonic energy method is capable of triggering biological effects based on both thermal and non-thermal mechanisms. The aim of the current study is to analyze methylene blue dispersion in polymethylmethacrylate beads, in association with the acoustic field generated by non-thermal ultrasound. Forty-nine specimens were used, and each specimen comprised one polymethylmethacrylate bead (0.6-mm diameter) doped with methylene blue and deposited in gelatin sample. Forty test specimens were divided into four groups comprising 10 samples, each, based on different ultrasound intensities (Group 1: 1.0 W/cm2; Group 2: 1.5 W/cm2) and polymethylmethacrylate bead depths (A - 2 cm; B - 3 cm) in gelatin sample. The control group comprised other nine specimens and statistically differed from the other groups. All groups irradiated with ultrasound have shown statistically significant differences in methylene blue dispersion, except for Groups 2A and 2B. Methylene blue dispersion in gelatin among groups was 1A&gt; 1B; 2A&gt; 1A; 2B&gt; 1A; 2A&gt; 1B; and 2B&gt; 1B. Low-intensity ultrasound enabled the highest methylene blue dispersion when polymethylmethacrylate bead was positioned superficial; bead depth associated with high-intensity ultrasound did not influence methylene blue dispersion.

title: Postoperative evaluation of analgesia promoted by the use of dexmedetomidine alone and associated with morphine as an intramuscular pre-anesthetic medication in bitches submitted for ovariohysterectomy

description: Abstract This study aimed to evaluate the postoperative analgesic efficacy of dexmedetomidine alone and when associated with morphine in patients under general inhalational anesthesia with isoflurane and undergoing elective ovariohysterectomy (OH). Twenty healthy bitches were selected via physical and laboratory examinations. Prior to the study, they underwent a 24-h period of adaptation to the environment and observers. They were then randomly divided into two groups: the dexmedetomidine group receiving a dose of 10 μg/kg, and dexmedetomidine group (10 μg/kg) associated with morphine receiving a dose of 0.3 mg/kg, administered via the intramuscular route. Thereafter, patients were induced with propofol and maintained with isoflurane diluted in 100% oxygen administered through a calibrated vaporizer. To verify postoperative analgesia, pain assessments were performed using the modified Glasgow (EGM) and Melbourne (EM) scales. For sedation assessment, the Dobbins scale was used at different times: before the administration of pre-anesthetic medication (T0) and at another six times in the postoperative period, 1 (T1), 2 (T2), 4 (T3), 8 (T4), 12 (T5), and 24 (T6) h after orotracheal extubation. No statistical differences were observed between groups in the scales according to Dunn’s Kruskal-Wallis post hoc test, and between the times a statistical difference was noticed by the Friedman test (p&lt;0.05) for the EGM and EM scale scores, but there was no need for analgesic rescue. Therefore, we found that isolated dexmedetomidine and morphine produced adequate analgesic effects in the postoperative period of bitches submitted for OH.

title: Benford or not Benford: new results on digits beyond the first

description: In this paper, we will see that the proportion of d as p^th digit, where p&gt;1 and d in [[0,9]], in data (obtained thanks to the hereunder developed model) is more likely to follow a law whose probability distribution is determined by a specific upper bound, rather than the generalization of Benford's law to digits beyond the first one. These probability distributions fluctuate around theoretical values of the distribution of the p^th digit of Benford's law. Knowing beforehand the value of the upper bound can be a way to find a better adjusted law than Benford's one.

title: Inference on parameter β of the Generalized Negative Binomial Distribution

description: In this paper, we propose a generalized likelihood ratio test to discern whether a set of data fits a Negative Binomial as a particular case of the Generalized Negative Binomial Distribution(GNBD). The test attempts to differentiate the GNBD from Negative Binomial (NBD) distribution when fitting discrete data. A Monte Carlo simulation study was performed to investigate the power and the size of the proposed test, and results shows good performance in power and size under moderate sample sizes of the LRT test for testing hypotheses on parameter β of the Generalized Negative Binomial Distribution. A Parametric Bootstrap for investigating the distribution of parameter β of the GNBD and a Bayesian approach for obtaining the posterior distribution of the GNBD parameters were also implemented. In order to illustrate the proposed methodology, we included two cases: a dataset of an entomological study on mosquitoes of malaria and another study on species of Malaysian butterflies.

title: Analysis of added value in bovines sold for the angus meat program in the south of Brazil

description: Abstract The objective of this work was to analyze price aggregation and disaggregation in commercialized animals searching for “Programa Carne Angus” benefits in the state of Rio Grande do Sul, Brazil. Data from 40,698 carcasses with Angus cattle racial pattern, slaughtered in a meat industry that performs the “Programa Carne Angus ”certification, during the 2014 year were analyzed. The aggregated value was calculated by the difference between the negotiated base price for the lot and the final price obtained by animal after the certification process. The disaggregation was calculated based on the factors preventing the animals from being included in the certification program. The results show that the major disqualifying factor in males with the racial pattern was carcass fatness, and for females was the dentition, which disqualified 34.3 and 12.7% respectively. Value breakdown from 7,177 disqualified animals due to lack of finishing, or advanced dentition, reached R$ 1,213,528.00, or US$ 369,077.86 (US$ 51.43 per head), an amount that is no paid on from the industry to rural producers.

title: Identifying changes in predictors of business failures during and after the economic crisis in Italy

description: Following the prolonged economic crisis of recent years, a new economic shake-up due to the COVID-19 pandemic is under way. We consider whether banks and financial institutions may apply the same models as before for credit scoring and predicting risk. In particular, we investigate the prediction of survival or failure of Small Business Enterprises in Italy between 2008 and 2013, and between 2013 and 2018, using logistic regression models based on baseline balance sheet data. By fitting appropriate models including interaction with the time period, we identify several major differences. Notably, the Investment Rigidity Ratio was very strongly associated with failure probability in the first period but not the second, and a low Tangible Assets Ratio had a much stronger protective effect in the first period than in the second.The effect of the age of the firm also differed between the periods: younger firms were at greater risk of failure than older firms in 2008-2013 but this was not seen in 2013-2018. Especially in times of major changes, it is vital that quantitative aids to decision-making should be valid and up-to-dabusinesste.

title: Bayesian and maximum likelihood inference approaches for the discrete generalized Sibuya distribution with censored data

description: This paper presents inferences under classical (maximum likelihood, ML) and Bayesian approaches for the parameters of the generalized Sibuya (GS) probability distribution considering complete and right censored lifetime data. Under a Bayesian approach, the joint posterior probability distributions of interest are estimated using Markov Chain Monte Carlo (MCMC) simulation methods. A comprehensive simulation study is carried out to assess the performance of the estimation procedure. The usefulness of the GS model is also assessed with applications to two real data sets. Despite its merits, one limitation of the generalized Sibuya distribution is that it does not present great flexibility of fit of the hazard function as compared to other existing lifetime models.

title: Clinical and anatomopathological study of urolithiasis in feedlot lambs subjected to diets with different phosphorus concentrations

description: Abstract Obstructive urolithiasis is common in farmed sheep and has a multifactorial etiology, but inadequate nutritional management is considered the most relevant condition for its occurrence. The objectives of this study were to verify the influence of two diets with different concentrations of calcium (Ca) and phosphorus (P) on the development of obstructive urolithiasis, and to describe the clinical and anatomopathological findings of the urinary system in sheep. Thirty male crossbred Santa Inês and Ile de France lambs were randomly distributed into two groups: Group 1 (G1, n = 15) - Ca: 1.9:1 P and 0.42% P; Group 2 (G2, n = 15) - Ca: P 1.5:1 and 0.65% P. The diets consisting of Coast-cross hay, soybean meal, wheat, and corn were provided for 90 consecutive days with water ad libitum. After the diagnosis of the disease, the lambs were subjected to clinical and surgical treatment, when necessary. Urolithiasis was detected in 36.7% (11/30) of lambs, 26.7% were asymptomatic and 10% (3/30) had urethral obstruction. A lamb was unobstructed after amputation of the urethral process and urethral catheterization, one died of bladder and uroperitoneum rupture, and another was sacrificed after the failure of perineal urethrostomy and cystostomy. The most frequent renal histopathological changes were vascular congestion, dilation, and tubular degeneration. Proteins in the tubular lumen were more pronounced in G2. The diets were rich in concentrate and had adequate Ca:P ratios, but caused calculogenesis, showing that excess minerals and a small amount of roughage can cause disease in the herd.
