Abstract With the expansion of urbanization, the increase of pollutants in air, soil and water is observed. The major source of Hg in urban soils is fossil fuel combustion, and these soils become important indicators of contaminants in the soil environment.The aim of the research was to determine the distribution of mercury in urban soil profiles on the basis of their physicochemical properties and origin.Analysed soils come from the city centre of Bydgoszcz, from park and square areas intended for recreation. Research was conducted on four soil profiles: Mollic Regosol (Technic), Skeletic Regosol (Technic), Eutric Regosol (Loamic), Eutric Regosol (Endoclayic). Determined in most profiles artefacts were pieces of bricks, concrete, glass, garbage, slag, asphalt, tar, and charcoals in proportion up to 25% of the volume. In soil samples basic soil parameters and the total content of mercury were determined (using atomic absorption spectrometer AMA-254).Determined parameters and the total mercury content of analysed soils of Bydgoszcz city were typical for urban areas, and the soils were classified as noncontaminated of this metal (total Hg content 0.009-1.114 mg.kg-1, mean 0.218 mg.kg-1). In most analysed soils the source of Hg was atmospheric deposition and addition of human-made materials. It was confirmed by significant correlation coefficient -0.415 (p<0.05), calculated between Hg content and percent of course fragments (Ø>2mm), among which artefacts were very common. Profile distribution of mercury was mainly the result of antropopression but also the concentration of Hg in parent material. Spatial differentiation of Hg content between tested soil profiles was related with localisation (vicinity of heavy traffic roads).

Full textAbstract:
La terapia dietetica svolge un ruolo fondamentale nel trattamento della malattia renale cronica (CKD): previene e corregge le complicanze metaboliche, garantisce il mantenimento o il raggiungimento di uno stato nutrizionale soddisfacente e, nella fase conservativa, ritarda l'inizio della terapia sostitutiva. Molte sono le evidenze che attestano che il trattamento nutrizionale effettuato da un dietista esperto migliora la qualità di vita del paziente con insufficienza renale cronica, aumenta l'eff -cacia della terapia dietetica e riduce i costi assistenziali. Negli Stati Uniti sono stati definiti i parametri che identificano il dietista esperto nella gestione della terapia nutrizionale nel paziente nefropatico e sono state individuate tre categorie in base al grado di formazione e competenza acquisita. Nei Paesi dell'Unione Europea la formazione dei dietisti è molto eterogenea tanto da rendere difficile una comparazione con la realtà americana. L'European Federation of the Association of Dietitians negli ultimi anni ha comunque definito gli standard accademici e professionali dei dietisti individuando quattro ruoli di competenza ed i relativi indicatori di performance. In Italia l'Associazione Nazionale Dietisti ha definito le posizioni dell'associazione in merito alla pratica professionale del dietista nel trattamento delle malattie renali e la Società Italiana di Nefrologia, nell'ambito del progetto di certificazione della qualità del percorso di cura della CKD, ha delineato il profilo del dietista che lavora in nefrologia ma non sono stati definiti standard accademici e professionali specifici. È auspicabile che dietisti esperti in nefrologia e nefrologi collaborino nel definire protocolli relativi a standard che il dietista operante in ambito nefrologico dovrebbe raggiungere in modo da garantire maggiore competenza professionale e una omogeneità di trattamento su tutto il territorio nazionale.

Adaptive adjustment of the relationship between the welding process parameters and the butt geometry permits to reduce the likelihood of welding defects appearance and improve the quality of the welded joint in automatic welding of large-diameter pipes. To obtain data on the configuration of the welded joint, the RF627 laser vision sensor is used. To reduce the influence of restrictions arising during the welding process, a median algorithm for filtering impulse noise is proposed. To calculate the geometric parameters of the welded joint, a model based on pixel data obtained from a laser sensor is proposed. The restoration of the welded butt parameters is carried out according to the algorithm of piecewise-linear approximation, which involves the determination of six characteristic points of the butt. The adaptive adjuster uses an inverse neural network model for adjustment the parameters of the welding process: welding current, voltage, wire feed speed. To train the neural network, the characteristic parameters of the welded butt are used: gap, skewing (warping of the edges) and bluntness (for the root weld), the current width of the butt groove in each layer (for other types of welds). The weights of the neural network layers are restored online using a gradient descent algorithm. The important role of the laser vision sensor in solving the problem of adaptation of welding equipment and the effectiveness of the proposed algorithms are confirmed experimentally.

Full textAbstract:
Il cancro al seno multifocale/multicentro (MF/MC) è una malattia che comprende molti paradigmi nell'attuale pratica del cancro al seno. Per combattere la morbilità e la mortalità di questo l'opzione migliore è una strategia terapeutica razionale, che dovrebbe iniziare con una chiara comprensione biologica della multicentricità e della multifocalità, poiché questo è noto, il trattamento corretto può essere seguito. Il nostro obiettivo era quello di definire il profilo dei pazienti con cancro al seno multifocale e multicentro e valutare se c'è disaccordo tra i foci tumorali per quanto riguarda il recettore ormonale e Her-2. Abbiamo analizzato retrospettivamente 89 pazienti con carcinoma mammario invasivo multifocale e multicentrico in due istituzioni terziarie nel nord-est del Brasile, valutando il recettore ormonale, Her-2 e ki67 in ogni focus tumorale di 25 di questi pazienti, evidenziando il disaccordo o meno tra di loro, e il tipo e il grado istologico, la metastasi dei linfonodi e la distanza e l'età. Di questi pazienti, il 9% presentava eterogeneità tra i foci tumorali. La percentuale di metastasi nel linfonodo ascellare era del 42% e solo del 10% per metastasi distanti. Il 45% delle donne nello studio aveva un grado istologico II o III. Abbiamo trovato una prevalenza di 40.5% di Her-2 negativo e 45% del recettore estrogeno positivo. Non c'era alcuna differenza statisticamente significativa tra il cancro multifocale e quello multicentrico. Concludiamo che il cancro al seno MF/MC mostra eterogeneità tra i foci tumorali in relazione ai parametri biologici, che svolge un ruolo cruciale nel prendere decisioni sul trattamento e di conseguenza sulla ricorrenza del tumore, la prognosi e la metastasi lontana.

Full textAbstract:
Con l'evoluzione dell'IoT e l'affermarsi di una concezione moderna di pratica medica, vengono introdotte nuove soluzioni nei percorsi di cura dei pazienti. Nell'AUSL di Piacenza, gli operatori sanitari del percorso terapeutico "Disturbi del comportamento alimentare" intendono sperimentare una nuova metodologia di cura dei propri pazienti, incentrata sulla continuità della cura stessa e sulla telecomunicazione. L'obiettivo è quello di monitorare i parametri vitali dei pazienti da remoto, utilizzando un'applicazione dedicata e alcuni dispositivi medici dotati di connettività wireless, che vengono forniti ai pazienti stessi per la raccolta dei parametri da analizzare. La tecnologia wireless adatta per questo tipo di utilizzo, considerando il requisito di basso consumo energetico dei dispositivi medici, è il Bluetooth Low Energy. In questo elaborato, vengono inizialmente descritti i componenti fondamentali di questa tecnologia: GAP e GATT. Successivamente, vengono descritte e approfondite le funzionalità principali di una componente autonoma realizzata per dispositivi Android, parte integrante di un'applicazione di monitoraggio in sviluppo. Le tre funzionalità in questione sono: pairing dei dispositivi, sincronizzazione e visualizzazione dei dati. Vengono descritti i processi di analisi, progettazione e implementazione della componente stessa, oltre al risultato finale che si intende realizzare e che costituirà un sistema di monitoraggio completo.

Objective of this diploma thesis was to evaluate internal environment of racehorses according to physical load. Experiment was done on ten english thoroughbred horses. These horses were prepared in training for the plain racing. Blood collections for analysis were done at rest, 5 and 10 minutes after physical load. Analysis were done by metabolic profile test. Biochemical and hematologic measurements were studied on horses. All horses showed high values of selen, from 278,62 to 337,48 umol/l. Thanks to biochemical measurements, at creatine kinases, the biggest value that was find out was 8,13 ukat/l at rest, after 5 minutes of rest, it was in range of 3,72 - 8,23 ukat/l and after 30 minutes, in range between 3,01 - 12,88 ukat/l. At rest the lactate was established at biggest value 6,58 mmol/l, after 5 minutes of rest values on all tested horses increased to biggest measured value 8,98 mmol/l. Factor LDH has increased too, after 5 minutes of rest it has increased from the standing point to the biggest measured value at 9,97 ukat/l. Intensive training of race horses causes that the tracked measurements arent going back to the optimal values after the 30 minute rest. Majority of tracked measurements, especially biochemical, exceeds upper minimum of reference values. We conclude that it would be appropriate adjusting the reference values and standards for english thoroughbred in physical load.
