Street art in urbe. Arte urbana nelle periferie romane

Rome in the past was the undisputed cradle of the arts, the imperative destination of the eighteenth-century grand tourists for its constant combination of old and new, humble and magnificent, forgotten and alive that made it unique in its picturesque being, as the Englishmen called it. Recently, Rome is playing once again that key role in the 21st century world. The scenario is mostly regarding the Roman suburbs, borderline not only geographically, but also culturally and socially, where external ugliness is often due to an original lack of aesthetic design or frequently subjects to carelessness and degradation. On this type of urban contest many street artists are involved with their works, directly in contact with the territory and its inhabitants. In this essay the focus is on the connection born from the involvement of artists and citizens, which leads to a legal, programmatic and connected artistic production. So, Art becomes a means of communication in places that are often voiceless and, at the same time, it always performs its function: trough the Beauty, Art re-qualifies and educates and in the meantime interacts with the various components of society, stimulating knowledge and civic sense of common good

Combination of Annealing Particle Filter and Belief Propagation for 3D Upper Body Tracking

3D upper body pose estimation is a topic greatly studied by the computer vision society because it is useful in a great number of applications, mainly for human robots interactions including communications with companion robots. However there is a challenging problem: the complexity of classical algorithms that increases exponentially with the dimension of the vectors’ state becomes too difficult to handle. To tackle this problem, we propose a new approach that combines several annealing particle filters defined independently for each limb and belief propagation method to add geometrical constraints between individual filters. Experimental results on a real human gestures sequence will show that this combined approach leads to reliable results

Black soldier fly larvae used for environmental enrichment purposes: Can they affect the growth, slaughter performance, and blood chemistry of medium-growing chickens?

IntroductionThis research has been aimed at evaluating the effects of live black soldier fly larvae (BSFL) (Hermetia illucens) on the growth, slaughtering performance, and blood parameters of medium-growing chickens.MethodsA total of 240, 28-day-old, Label Rouge Naked Neck chickens were allotted to four experimental groups, according to the gender (males-females) and to the absence (control group, C) or presence (larvae group, L) of a dietary supplementation with 10% live BSFL, on the basis of the expected average daily feed intake (ADFI) (6 replicates/diet, 10 chickens/replicate). The birds were weighed weekly, and the feed consumption was recorded to calculate the average live weight, feed conversion ratio (FCR), average daily gain (ADG), and the ADFI. At 82 days of age, 2 birds/replicate (12 birds/diet) were selected and slaughtered. The blood samples were collected, and the carcass traits (carcass, breast, thigh, and organ weights and yields) were assessed.Results and discussionsOverall, the administered live BSFL did not impair the growth and slaughtering performance, or the blood traits, while the C females showed a better FCR than the treated ones (P < 0.05). The live BSFL consumption time was longer for the females than for the males (P < 0.001). The weight of the immune organs (spleen and bursa of Fabricius) increased as the live BSFL supplementation increased (P < 0.05). Furthermore, the provision of live BSFL reduced the gamma glutamyl transferase (GGT, U/l) activity content in the blood (P < 0.05). Finally, both the leukocytes (%) and the monocytes (%) were more abundant in the C groups than in the larvae ones (P < 0.05 and P < 0.01, respectively). In short, the supplementation of live BSFL can be used successfully as an environmental enrichment, without affecting the growth performance of male birds. Furthermore, the immune organ activity could be enhanced by the provision of live BSFL

Black Soldier Fly live larvae as environmental enrichment in medium-growing chicken diet

Introduction. Few studies on the effects of live larvae provision in poultry have been previously conducted [1,2,3]. However, trials on the long-term provision of live larvae in chicken reared for meat consumption have never been performed before. This study evaluated the impact of Black Soldier Fly (BSF) live larvae provision on growth performance and larvae consumption behavior of intermediate-growing strains. Material and methods. A total of 240 Label naked neck birds were reared from 21 to 82 days of age, and four experimental groups (10 birds/pen, 6 replicates/treatment) were considered according to the birds’ gender and larvae provision. Experimental groups were fed 10% supplementation of BSF live larvae based on the daily feed intake. The live weight (LW), feed conversion ratio (FCR), average daily feed intake (ADFI) and average daily gain (ADG) were evaluated considering two periods: 21-35d and 35-82d. The larvae were provided daily and consumption times were analyzed considering periods of 10 days (5 time frame-T1,T2,T3,T4,T5). Data were analyzed by means of a GLMM (SPSS software, P<0.05). Results. The larvae groups displayed a lower ADFI than the control groups regardless the birds’ gender at 21-35d (P=0.01). This could be explained by the larvae nutritional contribution that led to a lower feed consumption in the experimental groups. Moreover, treated birds revealed a lower FCR than control groups (21-35d; P<0.001). Otherwise, only treated males performed a better FCR than control groups during the second period (P<0.01). Overall, time of larvae consumption at T1 and T5was respectively higher and lower than the other considered periods in both sexes (P<0.05). Such differences could be related to a progressive birds’ adaptation to larvae consumption. Significant differences between sexes were recorded only at T5, when females employed much time than males in larvae consumption (P<0.05). Conclusion. Live larvae provision ameliorated both the ADFI and FCR. Furthermore, the time of larvae consumption shrinked as birds became older. References. [1] Star L. et al. (2020). Animals. 10,216.

La radioterapia nelle metastasi cutanee da carcinoma mammario: case report

Breast cancer is the most frequent tumour in women around the world and it accounts for 25% of all cases of cancer. It may spread through the body in various districts, and as a consequence pulmonary, bone, liver, cerebral, lymph node and skin metastases are commonly seen. Skin metastases can be both locoregional (near the tumor) and distant. The skin appearance should not be underestimated in multi-metastatic patients, as tumorous progression in the skin inevitably causes ulceration, extreme difficulty in cicatrization and consequent pain. In this study, we describe the case of a multiple treated patient for destructive cutaneous metastases (Oncology)

Blood chemistry of medium-growing male and female chickens supplemented black soldier fly live larvae

Effects of live larvae provision on poultry chemical blood parameters have been poorly investigated. This study aims to evaluate the changes in blood chemistry parameters in medium-growing chickens supplemented black soldier fly (BSF) live larvae. Two hundred and forty 21d old sexed Label Naked Neck birds were divided into 4 experimental groups: females fed basal organic feed (BOF), males fed BOF, females fed BOF + 10% BSF live larvae supplementation based on the expected daily feed intake (DFI) and males fed BOF + 10% BSF live larvae supplementation based on the DFI (6 replicates/diet, 10 birds/replicate). Blood samples were collected at slaughter (82d old) from 2 birds/pen (12 birds/treatment). Serum samples were used for biochemical analysis. A compact liquid chemistry analyzer system (BT 1500 vet–Futurlab) was used to determine the concentrations of alanine aminotransferase (U/I), aspartate aminotransferase (U/I), creatinine total proteins (mg/dl), uric acid (mg/dl), cholesterol (mg/dl), triglycerides (mg/dl), gamma glutamyltransferase (GGT, U/I), phosphorus (mg/dl) and magnesium (mg/dl). Data were analyzed by GLMM (SPSS software, P<0.05). Overall, the blood parameters were not affected by the live larvae supplementation (P>0.05) in both sexes, thus being indicative of a good health status of the birds. Moreover, the GGT was detected in lower concentrations in the supplemented groups than in the control groups (P<0.05), suggesting a positive effect on the hepatic function. In conclusion, the live BSF larvae provision did not negatively affect the blood parameters of medium-growing chickens and could be beneficial for bird hepatic activity
