The Venetian Ghetto : Semantic Modelling for an Integrated Analysis

In the digital era, historians are embracing information technology as a research tool. New technologies offer investigation and interpretation, synthesis and communication tools that are more effective than the more traditional study methods, as they guarantee a multidisciplinary approach and analyses integration. Among the available technologies the best suited for the study or urban phenomena are databases (DB), the Geographic Information System (GIS), the Building Information Modelling (BIM) and the multimedia tools (Video, APP) for the dissemination of results. The case study described here concerns the analysis of part of Venice that changed its appearance from 1516 onwards, with the creation of the Jewish Ghetto. This was an event that would have repercussions throughout Europe, changing the course of history. Our research confirms that the exclusive use of one of the systems mentioned above (DB, GIS, BIM) makes it possible to manage the complexity of the subject matter only partially. Consequently, it became necessary to analyse the possible interactions between such tools, so as to create a link between an alphanumeric DB and a geographical DB. The use of only GIS and BIM that provide for a 4D time management of objects turned out to be able to manage information and geometry in an effective and scalable way, providing a starting point for the mapping in depth of the historical analysis. Software products for digital modelling have changed in nature over time, going from simple viewing tools to simulation tools. The reconstruction of the time phases of the three Ghettos (Nuovo, Vecchio, and Nuovissimo) and their visualisation through digital narratives of the history of that specific area of the city, for instance through videos, is making it possible for an increasing number of scholars and the general public to access the results of the study

Multivariate quality control of lubricating oils using Fourier transform infrared spectroscopy

Multivariate quality control in conjunction with Fourier transform infrared Spectroscopy (FTIR) were used to qualitatively detect the class and the condition of lubricating oils. The multivariate approach was based on principal component analysis (PCA), first to classify the lubricating oil type (mineral, synthetic and semi-synthetic) and then to develop two control charts: a T² chart using the most significant principal components and a Q chart with the PC not used in the first chart. From these two charts it was possible to identify oil samples, based on a viscosity parameter, which were out of the pattern normally present in utilizable lubricating oils.Controle de qualidade multivariado, em conjunto com espectroscopia no infravermelho por transformada de Fourier (FTIR), foi usado para detectar qualitativamente o tipo e a condição de óleos lubrificantes. O procedimento multivariado baseou-se na análise de componentes principais (PCA), primeiro para classificar o tipo do lubrificante (mineral, sintético e semi-sintético) e depois para desenvolver duas cartas de controle: uma carta T² usando os componentes principais mais significativos e uma carta Q com os componentes principais não utilizados na primeira carta. A partir destas duas cartas, foi possível identificar amostras de óleo, baseado no parâmetro da viscosidade, que se encontravam fora do padrão normalmente presente em lubrificantes em condições de uso.570576Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Vegetated ditches for the mitigation of pesticides runoff in the po valley

In intensive agricultural systems runoff is one of the major potential diffuse pollution path- ways for pesticides and poses a risk to surface water. Ditches are common in the Po Valley and can potentially provide runoff mitigation for the protection of watercourses. The effec- tiveness depends on ditch characteristics, so there is an urgent need for site-specific field trials. The use of a fugacity model (multimedia model) can allows recognition of the mitiga- tion main processes. A field experiment was conducted in order to evaluate the mitigation capacity of a typical vegetated ditch, and results were compared with predictions by a fugacity model. To evaluate herbicide mitigation after an extreme runoff, the ditch was flooded with water containing mesotrione, S-metolachlor and terbuthylazine. Two other sub- sequent floods with uncontaminated water were applied 27 and 82 days later to evaluate herbicides release. Results show that the ditch can immediately reduce runoff concentration of herbicides by at least 50% even in extreme flooding conditions. The half-distances were about 250 m. As a general rule, a runoff of 1 mm from 5 ha is mitigated by 99% in 100 m of vegetated ditch. Herbicides retention in the vegetated ditch was reversible, and the second flood mobilized 0.03-0.2% of the previous one, with a concentration below the drinking water limit of 0.1 \u3bcg L-1. No herbicide was detected in the third flood, because the residual amount in the ditch was too low. Fugacity model results show that specific physical-chemi- cal parameters may be used and a specific soil-sediment-plant compartment included for modelling herbicides behaviour in a vegetated ditch, and confirm that accumulation is low or negligible for herbicides with a half-life of 40 days or less. Shallow vegetated ditches can thus be included in a general agri-environment scheme for the mitigation of pesticides runoff together with wetlands and linear buffer strips. These structures are present in the land- scape, and their environmental role can be exploited by proper management

Determination of Viscosity and Solids in Pressure-Sensitive Adhesives by FTIR-ATR and Multivariate

Este trabalho apresenta o emprego da espectroscopia no infravermelho combinada com ferramentas quimiométricas para o controle de qualidade de adesivos. A partir de 105 espectros no infravermelho de amostras de adesivos de diferentes tipos de formulação empregou-se análise de componentes principais (PCA), sendo possível a separação das amostras em quatro diferentes grupos. A regressão por mínimos quadrados parciais (PLS) foi utilizada na quantificação do teor de sólidos a partir de um conjunto de 28 amostras de adesivos com base aquosa. O PLS por intervalos (iPLS) foi usado na determinação de viscosidade a partir de um conjunto de 73 amostras de adesivos com base solvente, obtendo-se erros menores que 7% em ambos os casos. Dessa forma, os resultados indicam que o emprego de ATR-FTIR, aliada a quimiometria, é uma excelente alternativa para o controle de qualidade de uma indústria de adesivos. This paper presents the application of infrared spectroscopy in conjunction with chemometric methods for quality control in adhesive manufacturing. From 105 infrared spectra of pressuresensitive adhesive samples of different formulations, employing principal component analysis (PCA), it was possible the separation in four groups. By using partial least squares regression (PLS), the solid contents of 28 samples of water-based adhesive were determined. The interval-PLS (iPLS) was used for the determination of the viscosity of 73 solvent-based adhesive samples, with errors less than 7% in both cases. These results indicate the feasibility of employing ATR-FTIR and chemometrics as an attractive alternative for quality control in adhesive manufacturing

Juvenile Panhypopituitarism in a Dog – What are the Therapeutic Challenges?

Background: Juvenile panhypopituitarism is an endocrinopathy that affects young dogs and must be differentiated from other causes of height disorders, as one could have a deficiency of one or more adenohypophysis hormones, besides growth hormone. Diagnosis consists of excluding endocrine and non-endocrine causes. Treatment requires administration of heterologous porcine growth hormone or progestins, as well as supplementing other hormones that are deficient in the circulation. The prognosis for these patients tends to be unfavorable and they have a shorter life expectancy. The present case aimed to report the therapeutic challenges in a dog diagnosed with juvenile panhypopituitarism. Case: This study presents the case of a 6-month-old crossbred Labrador/Brazilian Fila dog, not neutered, 6.7 kg of body weight (body condition score 5/9), with a growth disorder and persistence of the puppy coat, when compared to other members of the same litter. During inspection, it was possible to observe an undersized dog and soft puppy coat, besides no bone irregularities or joint tenderness was noted. The other physical examination parameters were within the normal range for the species. No changes in complete blood count and only increases in urea, cholesterol and alkaline phosphatase activity were observed. Thyroid and abdominal ultrasound (US) examination did not reveal any remarkable changes. After serum dosage of insulin-like growth factor, thyroxine, thyrostimulating hormone, and cortisol, the patient was diagnosed with juvenile panhypopituitarism and underwent therapy with medroxyprogesterone and thyroid hormone supplementation. Monitoring was instituted at intervals of 3, 6, and 12 weeks, and currently every 3 or 4 months and the IGF-1 values normalized after 6 months with. After 8 months of therapy, the patient had good body growth and bone mineralization compared to the time of diagnosis. However, skeletal development was completed only 12 months after hormone replacement, accompanied by the presence of vertebral osteophytes and coxofemoral osteoarticular alterations. Considering chronic use of progestins, ovariosalpingohysterectomy (OSH) was recommended, but for personal reasons, the owners chose to do not submit her to surgery. After 18 months of treatment, the dog starts to exhibit prostration, selective appetite, and increased abdominal volume. After imaging exam, she was forwarded for OSH, due to consistent findings of pyometra. Subsequently, even the supervision of possible comorbidities involved in the chronic use of progestins was maintained at half-yearly intervals, the bitch returned to the service with skin thickening, increased limb volume, and macroglossia after 60 months of therapy. At this point IGF-1 values were higher when compared to the previous measurements and the application of medroxyprogesterone was suspended. Its supplementation was reintroduced only after 8 months when IGF-1 was significantly reduced. To date, the patient is close to 6 years of age and with a good quality of life. Discussion: The greatest therapeutic challenge for these patients involves dealing with the adverse effects of progestins, mainly related to reproductive disorders and alopecia at the application site, as well as maintaining adequate hormone replacement in order to avoid hypersomatotropism. Although longevity is lower in these individuals, the patient in this report has achieved six years of age and has had an excellent quality of life so far.

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
