Selected fruits and seeds preserved as molds and casts in sediments from the Anjou flora of Maine-et-Loire have been reexamined with the aid of X-ray tomography. Virtual casts and surface renderings from micro-CT scanning data reveal external and internal morphological characters that were not visible by standard reflected light microscopy. Application of this methodology leads to a revision of the fruit formerly treated as Juglandicarya. It is a 5-valved capsule of likely sapindalean affnity, and is placed in Vaudoisia gruetii (Vaudois-Miéja) gen. et. comb. nov. A seed with the characteristic rumination of Anonaspermum is also recognized for the #rst time, as are capsular fruits of Ericaceae. We note that many disseminules are hidden from optical viewing because they are buried within the hand samples. A more extensive micro-CT scan investigation of more samples, including those showing only fossil leaf impressions at the surface, may be expected to yield a wealth of new information on this classic flora., Copyright © 2022 Société botanique de France.

Bakalářská práce se zabývá komplexním restaurátorským zásahem na sádrovém modelu sochy Touhy z depozitáře Vily Stanislava Suchardy v Praze. Touha byla následně realizována ve dvojnásobném měřítku v bronzu coby jedna z postav skupiny Historie na zadní straně pomníku Františka Palackého. Kromě několika přípravných návrhů celého pomníku se dochovala tato plastika jako jediná samostatná figura z Palackého pomníku, patrně proto, že modelem stála Suchardova dcera Marta. Jedná se o samostatné řešení restaurátorského úkolu v plném rozsahu od zpracování koncepce restaurování přes důkladný restaurátorský, umělecko - historický a chemicko - technologický průzkum až po vlastní restaurování a zpracování restaurátorské dokumentace. Průzkumová zpráva kriticky vyhodnocuje a srovnává testované materiály a postupy pro restaurování s přihlédnutím k rešerši. Na konci dokumentace je přiložena fotografická a grafická dokumentace mapující podrobně stav před restaurováním, celý postup prací a stav po restaurování a výsledky laboratorních průzkumů., This thesis presents a complex restoration treatment on a plaster cast depicting a Desire. It belongs to the collection of the Stanislav Sucharda Foundation and Museum. The plaster cast was later fabricated in bronze in a twice bigger size to be installed as one of the figures from the group History on the reverse of František Palacký monument in Prague. Apart from a few preliminary plaster casts of the whole of Palacký monument, this cast depicting a Desire is the only freestanding figure extant to this day, presumably from the reason, that as a model was standing Sucharda's daughter Marta. The thesis consists of detailed restoration research, the conception of the treatment and a description of the plaster cast. It contains further the restoration treatment itself with photographic and graphic documentation. The research report critically evaluates tested materials and technological methods, which were applied to the restoration of this plaster sculpture taking into account previous in-depth research. At the end are attached the results of a technological survey, complete photographic documentation of a condition before restoration, restoration works, and a state after treatment., Fakulta restaurování, Studentka formou ppt prezentace představila restaurování zadané skulptury. Reagovala na vznesené dotazy a drobné připomínky v posudcích. Vzhledem ke kvalitě provedených prací, restaurátorské dokumentace, resp. bakalářské práce, komise doporučila hodnocení "A"., Dokončená práce s úspěšnou obhajobou

BACKGROUND: Non-removable knee-high devices are the gold-standard offloading treatments to heal plantar diabetic foot ulcers (DFUs). These devices are underused in practice for a variety of reasons. Recommending these devices for all patients, regardless of their circumstances and preferences influencing their ability to tolerate the devices, does not seem a fruitful approach. PURPOSE: The aim of this article is to explore the potential implications of a more personalized approach to offloading DFUs and suggest avenues for future research and development. METHODS: Non-removable knee-high devices effectively heal plantar DFUs by reducing plantar pressure and shear at the DFU, reducing weight-bearing activity and enforcing high adherence. We propose that future offloading devices should be developed that aim to optimize these mechanisms according to each individual's needs. We suggest three different approaches may be developed to achieve such personalized offloading treatment. First, we suggest modular devices, where different mechanical features (rocker-bottom sole, knee-high cast walls/struts, etc.) can be added or removed from the device to accommodate different patients' needs and the evolving needs of the patient throughout the treatment period. Second, advanced manufacturing techniques and novel materials could be used to personalize the design of their devices, thereby improving common hindrances to their use, such as devices being heavy, bulky, and hot. Third, sensors could be used to provide real-time feedback to patients and clinicians on plantar pressures, shear, weight-bearing activity, and adherence. CONCLUSIONS: By the use of these approaches, we could provide patients with personalized devices to optimize plantar tissue stress, thereby improving clinical outcomes., Funding agencies:National Health and Medical Research Council (NHMRC) of Australia 2014165 Urgo Foundation

Microbial necromass is a central component of soil organic matter (SOM), whose management may be essential in mitigating atmospheric CO2 concentrations and climate change. Current consensus regards the magnitude of microbial necromass production to be heavily dependent on the carbon use efficiency of microorganisms, which is strongly influenced by the quality of the organic matter inputs these organisms feed on. However, recent concepts neglect agents relevant in many soils: earthworms. We argue that the activity of earthworms accelerates the formation of microbial necromass stabilized in aggregates and organo-mineral associations and reduces the relevance of the quality of pre-existing organic matter in this process. Earthworms achieve this through the creation of transient hotspots (casts) characterized by elevated contents of bioavailable substrate and the efficient build-up and quick turnover of microbial biomass, thus converting SOM not mineralized in this process into a state more resistant against external disturbances, such as climate change. Promoting the abundance of earthworms may, therefore, be considered a central component of management strategies that aim to accelerate the formation of stabilized microbial necromass in wide locations of the soil commonly not considered hotspots of microbial SOM formation.

SiOcast es una empresa que posee un sistema único de inyección de termoplástico en molde de silicona. Es un sistema revolucionario en el mundo de las miniaturas ya que es muy diferente y ventajoso sobre los otros sistemas que hay actualmente en el mercado. SiOcast vende a sus clientes todas las herramientas y procedimientos para llevar a término este proceso, desde la silicona para hacer los moldes, como el portamoldes para crearlos, y hasta la máquina y la resina para inyectar los moldes, y con éste proyecto se pretende crear un post-proceso para esta lınea de trabajo. Actualmente este post-proceso es totalmente manual y la intención de este proyecto es introducir este post-proceso en la robotización y automatización. Para conseguirlo se quiere utilizar un robot de sobremesa para alimentar una guillotina que se tendrá que diseñar desde 0, ésta nos permitirá extraer la parte central de la inyectada, es decir el mayor residuo, para posteriormente poder tratar mejor las piezas resultantes de este proceso. Sobre el tratamiento de estas piezas también se hará un estudio de qué pasos se deberían dar para poder separar la pieza del punto de inyección y que ésta esté preparada para pasar el control de calidad, conteo y clasificaci´on para ser enviada al cliente final. Para alimentar el sistema de corte se ha elegido un robot de sobremesa de la marca Rotrics, el Dexarm, la guillotina se ha diseñado tal y como era la idea y el sistema ha funcionado bien aunque falta nivel de precisión y repetibilidad por parte del robot. El proyecto ha tenido un coste de 1.901,17€ más de 1200h de trabajo a 20€/h hacen un total de 25.901,17€, SiOcast is a company that owns a unique thermoplastic injection in silicone mold. It is a revolutionary system in the world of miniatures as it is very different and advantageous over other systems currently on the market. SiOcast sells to its customers all the tools and procedures to carry out this process, from the silicone to make the molds, such as the mold holder to create them, and to the machine and the resin to inject the molds, and this project aims to create a post-process for this line of work. Currently this post-process is completely manual and the intention of this project is to introduce this post-process to robotics and automation. In order to achieve this we want to use a desktop robot to feed a guillotine that must be designed from 0, this will allow us to extract the central part of the injected, the largest residue, to later be able to better treat the parts resulting from this process. On the treatment of these pieces will also do a study of what steps should be taken to separate the piece from the injection point and that it is ready to pass the quality control, counting and classification to be sent to the end customer. To feed the cutting system, a desktop robot from the Rotrics brand, the Dexarm, the guillotine has been designed as it was thought and the system worked but we need more precision and repetibility from the robot. The project has cost 1,901.17€ plus 1200 hours of work at 20€/h making a total of 25,901.17€., SiOcast es una empresa que posseeix un sistema únic d’injecció de termoplàstic en motlle de silicona.

Documentation and examination are the essence of runological fieldwork. As discussed here, the recording aspect concerns the inscriptions, particularly the runes, themselves. The documentation of runic carvings is a multifaceted activity. It ranges from the production of reading protocols during the examination of inscriptions to the utilization of various techniques for registering what is found on the runic object: (a) visually, i.e. with drawings or photographs, (b) physically, e.g. with squeezes or casts, and (c) scientifically, such as by employment of microscopes, 3D scanning, or most recently Reflectance Transformation Imaging. The main requirement for all such documentation is objectivity., https://doi.org/10.33063/diva-438865

BackgroundThe Ponseti method is the standard of care for managing idiopathic congenital talipes equinovarus (clubfoot) in the outpatient setting, but there are no clinical guidelines for inpatient treatment. Children in the neonatal intensive care unit (NICU) with clubfoot often delay treatment initiation due to medical reasons.MethodsWe systematically reviewed literature related to the treatment of clubfoot in the NICU, non-idiopathic clubfoot, and older infants, as well as barriers to care.ResultsIn a mixed NICU population of syndromic and idiopathic clubfoot, the Ponseti method has good functional outcomes with minimal interference with medical management. The Ponseti method has good functional outcomes with reduced need for extensive surgical procedures in non-idiopathic clubfoot and idiopathic clubfoot with delayed presentation (under one year of age).ConclusionsIt is possible to begin Ponseti treatment in the NICU without compromising medical management. It is not clear if this confers an advantage over waiting for outpatient casting.

Aquest projecte tracta de re-dissenyar tan formalment com modificar el material amb el qual es fabrica, un component basat a unir els perfils d’un moble nomenat Nodum de l’empresa JG Group. L’objectiu d’aquest re-disseny és acabar fabricant la peça amb un motlle d’injecció de plàstic. Per dur a terme aquest projecte es partirà d’unes peces i uns plànols proporcionats per l’empresa JG Group. S’estudiaran els materials que poden servir per a substituir a l’actual (Zamak) a partir d’analitzar les característiques necessàries que ha de tenir el component re-dissenyat. Posteriorment d’aquest anàlisis es compararan els materials entre si per a escollir l’idoni. S’estudiarà la peça i l’àmbit on anirà col·locada. Seguidament s’analitzaran les seves inconsistències per a posteriorment oferir diferents propostes que milloraran/ igualaran les prestacions que ofereix l’actual. Les propostes seran modelades amb SolidWorks i impreses en 3D per comparar l’adaptació amb els perfils i escollir el re-disseny idoni. Un cop escollit el material i el re-disseny estructural, es realitzaran una sèrie de simulacions per a extreure el gruix idoni de les parets amb Zamak, posteriorment s’adaptarà el disseny al plàstic. Posteriorment es realitzarà el disseny del motle per a la seva fabricació, a partir de l’estudi de la peça i dels components que formen el motlle. Per a finalitzar s’analitzarà els costos de disseny del motlle.

Las Exposiciones Internacionales y Universales fueron durante la segunda mitad del siglo XIX y el primer cuarto del siglo XX los grandes eventos mundiales. Estas ferias servían como lugar de exhibición de los adelantos que cada nación participante había hecho en materia de ciencia y tecnología. Su popularidad hasta el cambio de siglo hizo de las exhibiciones el lugar predilecto en el que mostrar los avances en todas sus facetas. Por ello, estos multitudinarios eventos ejercieron asimismo como tablero en el que se puede observar la política internacional del momento. Dentro de esta función de exhibición internacional, presenciamos la consolidación de las identidades nacionales que se forjaron durante el siglo XIX. En las identidades nacionales cumple una función primordial la legitimación histórica de las mismas. Es por esta razón por la que en las Exposiciones Internacionales y Universales se exhiben piezas de valor arqueológico que representen el pasado de la nación. En este trabajo analizamos el papel que tuvo la arqueología ibérica en estos foros, y especialmente las estatuas del Cerro de los Santos, aparecidas fundamentalmente en la década de 1870. Además, analizamos la importancia de la presencia ibérica en estas Exposiciones para llegar a definir y confirmar su propia personalidad histórica., International exhibitions were the greatest worldwide events during the second half of the 19th century and the first quarter of the 20th century. These fairs functioned as scenarios where each nation could exhibit its scientific and technological developments. The popularity of these international fairs until the end of the 19th century, turned them into the perfect place for nations to show their scientific progresses as well as their economical and political growth. Due to this reason, these events acted at the same time as a board to play international relations. In the same way, the consolidation of the different national identities created during the 19th century can be observed. One key factor inside national identities is historical legitimization and, as a consequence, the exhibition of archaeological objects is aimed to represent each nation’s past. On this essay, we analyse the function of Iberian archaeology in these fairs, giving special attention to the statues of Cerro de los Santos’, which were discovered during the decade of 1870.

Background: The aim of this study was to quantify the stabilizing properties of a 3-dimensional (3D)-printed short-arm cast and compare those properties with traditional fiberglass casts in a cadaveric subacute distal radius fracture model. Methods: A cadaveric subacute fracture model was created in 8 pairs of forearms. The specimens were equally allocated to a fiberglass cast or 3D-printed cast group. All specimens were subjected to 3 biomechanical testing modalities simulating daily life use: flexion and extension of digits, pronation and supination of the hand, and 3-point bending. Between each loading modality, radiological evaluation of the specimens was performed to evaluate possible interval displacement. Interfragmentary motion was quantified using a 3D motion-tracking system. Results: Radiographic assessment did not reveal statistically significant differences in radiographic parameters between the 2 groups before and after biomechanical testing. A statistically significant difference in interfragmentary motion was calculated with the 3-point bending test, with a mean difference of 0.44 (±0.48) mm of motion. Conclusions: A statistically significant difference in interfragmentary motion between the 2 casting groups was only identified in 3-point bending. However, the clinical relevance of this motion remains unclear as the absolute motion is less than 1 mm. The results of this study show noninferiority of the 3D-printed casts compared with the traditional fiberglass casts in immobilizing a subacute distal radius fracture model. These results support the execution of a prospective randomized clinical trial comparing both casting techniques.

BACKGROUND: Early evaluation and appropriate management of pediatric scaphoid fractures are necessary to avoid complications. To date, current management of pediatric fractures varies among providers. The objective of this study was to compare clinical outcomes following different treatment modalities. METHODS: A PubMed literature search identified studies involving acute scaphoid fractures in children. Studies were evaluated for treatment provided and their respective effects on union rate, wrist range of motion, and wrist pain. Data were pooled across studies, and quantitative statistical analysis was conducted to compare outcomes. RESULTS: Seventeen studies representing 812 acute pediatric scaphoid fractures were included in the current analysis. We found 93.5% of scaphoid fractures were treated with cast immobilization vs 6.5% treated surgically as 13 of 17 authors treated all fractures with immobilization vs 4 of 17 studies who offered surgical intervention. We found pediatric scaphoid fractures had excellent bone union rates (96.2%) with no difference between the cast immobilization and surgery groups ( P value NS). Long- and short-arm thumb spica immobilization protocols were commonly employed; however, we found no difference in the rates of union ( P value NS). At follow-up, 99.0% of patients treated nonoperatively had normal wrist range of motion and 96.8% were pain free. CONCLUSIONS: Pediatric scaphoid fractures have excellent outcomes. Nonoperative treatment results in a high rate of union with few posttreatment wrist symptoms. Nonsurgical treatment represents an adequate treatment modality in a majority of acute pediatric scaphoid fractures, wherein the role for surgery needs to be better defined.

PURPOSE. The purpose of this study is to assess the accuracy of three intraoral scanners along the complete dental arch and evaluate the feasibility of the assessment methodology for further in vivo analysis. MATERIALS AND METHODS. A specific measurement pattern was fabricated and measured using a coordinate measuring machine for the assessment of control distances and angles. Afterwards, the pattern was placed and fixed in replica of an upper jaw for their subsequent scans (10 times) using 3 intraoral scanners, namely iTero Element1, Trios 3, and True Definition. 4 reference distances and 5 angles were measured and compared with the controls. Trueness and precision were assessed for each IOS: trueness, as the deviation of the measures from the control ones, while precision, as the dispersion of measurements in each reference parameter. These measurements were carried out using software for analyzing 3-dimensional data. Data analysis software was used for statistical and measurements analysis (alpha=.05). RESULTS. Significant differences (P<.05) were found depending on the intraoral scanner used. Best trueness values were achieved with Hero Element1 (mean from 10 +/- 7 mu m to 91 +/- 63 mu m) while the worst values were obtained with Trios3 (mean from 42 +/- 23 mu m to 174 +/- 77 mu m). Trueness analysis in angle measurements, as well as precision analysis, did not show conclusive results. CONCLUSION. iTero Elementl was more accurate than the current versions of Trios3 and True Definition. Importantly, the proposed methodology is considered reliable for analyzing accuracy in any dental arch length and valid for assessing both trueness and precision in an in vivo study.

PURPOSE. The purpose of this study is to assess the accuracy of three intraoral scanners along the complete dental arch and evaluate the feasibility of the assessment methodology for further in vivo analysis.

Background: Non-removable offloading devices are recommended for the treatment of uncomplicated plantar diabetic foot ulcers because adherence to using removable devices is low. However, patients may not always understand how crucial the non-removability is to ulcer healing, leaving them with the impression that it is the device per se that heals the ulcer. Thus, after ulcer healing when patients return to using removable offloading devices, typically therapeutic footwear, they often return to a low level of adherence resulting in high reulceration rates. To change this pattern of behavior based on a misconception, we need to start with how we as clinicians are conceptualizing treatment with offloading devices. Non-removable offloading devices as commitment devices: Commitment devices are voluntary restrictions people put on their future selves to resist short-term temptations and achieve long-term goals. In this paper, it is suggested that a change from viewing non-removable offloading devices as means to force compliance, to viewing them as commitment devices could facilitate a change to a clinical thinking that emphasizes the importance of high adherence without compromising respect for patient autonomy. Conclusion: Viewing non-removable offloading devices as commitment devices seems to be a promising approach to emphasize the importance of adherence while respecting patient autonomy. Hopefully, patients' higher appreciation of the role of adherence can lead to higher adherence to using therapeutic footwear after healing and consequently to reduced reulceration rates.

Avui dia, el plàstic és un element de gran importància a la nostra societat. El seu ús i producció han experimentat un creixement exponencial durant l’últim segle degut a la seva versatilitat i fàcil manipulació. Moltes de les seves aplicacions requereixen l’ús de motlles d’injecció de plàstic. En aquest treball hem estudiat les variacions de pressió durant aquests cicles. En particular, hem dissenyat una pe¸ca de plàstic i hem fabricat el motlle per crear-la, on hi hem instal·lat un sensor piezoelèctric per mesurar la pressió a l’interior de la cavitat. Tot i que les mesures empíriques obtingudes difereixen lleugerament de les teòriques, els resultats obtinguts han estat prou significatius com per constatar que les variacions de la pressió reflecteixen defectes en les peces. La relació directa entre aquests dos fenòmens és d’especial interès en la indústria, ja que demostra que un control apropiat permet optimitzar el procés.

BackgroundEarly evaluation and appropriate management of pediatric scaphoid fractures are necessary to avoid complications. To date, current management of pediatric fractures varies among providers. The objective of this study was to compare clinical outcomes following different treatment modalities.MethodsA PubMed literature search identified studies involving acute scaphoid fractures in children. Studies were evaluated for treatment provided and their respective effects on union rate, wrist range of motion, and wrist pain. Data were pooled across studies, and quantitative statistical analysis was conducted to compare outcomes.ResultsSeventeen studies representing 812 acute pediatric scaphoid fractures were included in the current analysis. We found 93.5% of scaphoid fractures were treated with cast immobilization vs 6.5% treated surgically as 13 of 17 authors treated all fractures with immobilization vs 4 of 17 studies who offered surgical intervention. We found pediatric scaphoid fractures had excellent bone union rates (96.2%) with no difference between the cast immobilization and surgery groups ( P value NS). Long- and short-arm thumb spica immobilization protocols were commonly employed; however, we found no difference in the rates of union ( P value NS). At follow-up, 99.0% of patients treated nonoperatively had normal wrist range of motion and 96.8% were pain free.ConclusionsPediatric scaphoid fractures have excellent outcomes. Nonoperative treatment results in a high rate of union with few posttreatment wrist symptoms. Nonsurgical treatment represents an adequate treatment modality in a majority of acute pediatric scaphoid fractures, wherein the role for surgery needs to be better defined.

Inledning: Mikroskopisk analys av urinsediment anses i dagsläget vara gold standard inom urinsedimentdiagnostik, trots att metoden ofta är otillräckligt standardiserad. En rad automatiserade instrument, såsom UF-5000, finns idag tillgängliga och kompenserar för problematiken med den gamla metoden. Analys av urinsediment är avgörande vid flertal njursjukdomar, där bland annat erytrocyter, leukocyter, epitelceller, cylindrar och kristaller är av stort diagnostiskt värde. Syfte: Syftet var att utvärdera det automatiserade urinpartikelinstrumentet UF-5000 samt att jämföra metoden med manuell ljusmikroskopering av urinsediment. Metod: Vid metodjämförelse analyserades 69 prover med instrumentet UF-5000 samt i mikroskop. Data bearbetades med Passing Bablok-regression, Bland-Altman differensanalys samt Spearmans rangkorrelationkoefficient. Resultat: Statistisk signifikant skillnad förekom vid metodjämförelsen. Utvärderingen av instrumentet visade hög mätnoggrannhet med undantag för variationskoefficienten vid låg leukocytkoncentration samt avvikelser för instrumentets linjäritet. Diskussion: Då ljusmikroskopering av urinsediment är en otillräckligt standardiserad metod kunde statistiskt signifikanta skillnader ses, vilket kan bero på den bristande referensmetoden. Fortsatta studier där automatiserad metod jämförs med en mer standardiserad manuell mikroskopi är av stor vikt. Även reducering av cut-off för diverse parametrar kan vara aktuellt. Instrumentutvärdering visade en generell mätnoggrannhet med enstaka undantag vilket kan bero på felhantering vid analys. För vidare analys av linjäritet skulle ett ytterligare instrument som komplement kunna användas., Introduction: Microscopy is gold standard for urine sediment analysis, although the method is often insufficiently standardized. Several automated instruments, such as UF-5000, are commercially available on the market. Urine sediment analysis is crucial for diagnosis of kidney and urinary tract diseases where elements such as erythrocytes, leukocytes, epithelial cells, casts and crystals can be identified. Aim: The aim was to evaluate the performance of UF-5000 and compare the method with manual microscopic analysis of urine sediment. Method: Analysis with UF-5000 and microscopy was conducted on 69 samples. Data were processed with Passing Bablok-regression, Bland-Altman bias plot and Spearman's rank order correlation. Result: Comparison showed statistical significance between the two methods. Performance evaluation showed high accuracy apart from the coefficient of variation for low concentration of leukocytes and systematic error for linearity. Discussion: Since microscopy of urine sediment is an insufficiently standardized method, differences were acknowledged caused by discrepancies in the reference method. Further studies where UF-5000 is compared to a more standardized manual microscopy with a larger amount of pathological urine samples is of great importance. Reduction for cut-off may also be relevant. For further analysis of linearity, an additional instrument should be used as a complement.

This thesis is a case study examining a collection of Victorian era glass seal matrix casts, titled the Laing Seal Collection. Held by Otago Museum (OM), these glass casts make up what this research terms a “low-priority collection”: a collection that does not place highly within the collection policy and as a result receives no resources or research and little staff attention. By examining internal documents from Otago Museum, and interviewing key staff members, the objective of this research was to divine why these low priority collections endure. By examining the history of the Seal Collection this research aims to better understand how collections come to be decontextualised. Through tracing both the provenance of the Seal Collection and its history at Otago Museum this research hoped to discover how and why the collection became unknown. The lenses of material culture and organisational memory are used to better understand how staff memories become the last bastion for historical collection data that is not recorded. This makes that information susceptible to forgetfulness and staff transitions. The research shows that the Laing Seal Collection has no discoverable accession documentation, nor historical records indicating when or why it came to Otago Museum. However, this research did succeed in beginning the process of cataloguing and identifying the Collection and revealed a connection from Laing to Dunedin. It also argues that for the Laing Seal Collection to flourish as a collection, agency must be taken by staff members and the collection be fully integrated into Otago Museum’s Collection Management System. The future of the collection will entirely depend on how many staff resources are dedicated to it.

Distal radius fractures are widespread in the pediatric population. Standardized treatment protocols have not been well defined. We sought to examine the diversity of current practice patterns in the treatment of these fractures by surveying hand, pediatric, and general orthopedic surgeons. Hand, pediatric, and general orthopedic surgeons were surveyed using an internet-based questionnaire on the management of pediatric distal radius fractures. Each surgeon was asked to select a criterion from among choices of 'acceptable' alignment criteria at the onset of the survey. Ten cases were then provided to represent a broad spectrum of injuries from minimally angulated torus fractures to complete, displaced fractures. In addition to the variation in injury pattern, the patients in the survey differed in age at the time of injury (3-15 years of age). For each case, surgeons were asked to select a preferred treatment, first on the basis of injury films, and then again after reviewing 1-week follow-up radiographs. A total of 781 surgeons completed the survey. In patients younger than 9 years of age, a residual sagittal angulation of 20° or less, coronal angulation of 10° or less, and 1 cm or less of bayonet apposition was deemed 'acceptable' by 88, 90, and 69% of respondents, respectively. In older patients, these percentages were 58, 64, and 29%, respectively. When specific cases were reviewed, 20.3% of surgeons recommended treatment different from their own theoretical 'acceptable' criteria. When subspecialty training was analyzed, hand surgeons and general orthopedic surgeons were 2.9 and 1.6 times more likely to recommend surgery, respectively, as compared with pediatric surgeons after viewing the initial radiograph. Private practice surgeons were 1.5 times more likely to recommend surgery compared with academic surgeons based on the initial injury radiographs. Our survey highlights the discordance between theoretical acceptable criteria of surgeons and their practice ha

En este proyecto se ha trabajado con una novedosa técnica de moldeo, basada en el uso energía de ultrasonidos. Éste equipo de moldeo nace de la necesidad de obtener una técnica de moldeo de micro piezas más eficiente; sobre todo en el campo de la medicina y electrónica. En anteriores trabajos se ha demostrado la viabilidad de esta técnica para moldear micro piezas ofreciendo grandes ventajas sobre el resto de técnicas de micro-moldeo. Es por ello que en el presente trabajo se ha estudiado la posibilidad de producir micropiezas con un valor añadido. En concreto, piezas de polímero cargadas con agentes antibacterianos y por otra parte la incorporación de arcillas para formar nanocompuestos. El polímero escogido como matriz es la poliláctida (PLA) debido a su biocompatibilidad, su biodegradabilidad y la capacidad de obtenerse a partir de fuentes renovables. En una etapa previa del proyecto se han determinado las condiciones adecuadas de moldeo para la PLA: fuerza, amplitud y tiempo. Las condiciones se analizan según: un correcto llenado del molde, una mínima degradación del polímero, la ausencia de microfisuras derivadas de fenómenos de cavitación, el mantenimiento o mejora de las propiedades mecánicas y térmicas de las piezas. La caracterización se realiza mediante cromatografía de permeación en gel (GPC), espectrofotometría infrarroja (FTIR), ensayos mecánicos, microscopia electrónica de barrido (SEM) y calorimetría diferencial de barrido (DSC). Se ha demostrado la viabilidad de esta técnica para la obtención de nanocompuestos derivados de arcillas tanto sin modificar o modificadas con un agente orgánico que actúe como compatibilizador. Los ensayos de difracción de rayos X y la observación directa de las piezas mediante microscopia electrónica de transmisión (TEM) permitieron concluir que las láminas de las arcillas se encontraban totalmente separadas entre sí, nanocompuesto exfoliado, por lo que esta técnica presenta grandes ventajas frente a otros métodos de obtenc

PurposeTo evaluate a semiautomatic software-based method of registering in vivo prostate MR images to digital histopathology images using two approaches: (i) in which the prostates were molded to simulate distortion due to the endorectal imaging coil before fixation, and (ii) in which the prostates were not molded.Materials and methodsT2-weighted MR images and digitized whole-mount histopathology images were acquired for 26 patients with biopsy-confirmed prostate cancer who underwent radical prostatectomy. Ten excised prostates were molded before fixation. A semiautomatic method was used to align MR images to histopathology. Percent overlap between MR and histopathology images, as well as distances between corresponding anatomical landmarks were calculated and used to evaluate the registration technique for molded and unmolded cases.ResultsThe software successfully morphed histology-based prostate images into corresponding MR images. Percent overlap improved from 80.4 ± 5.8% before morphing to 99.7 ± 0.62% post morphing. Molded prostates had a smaller distance between landmarks (1.91 ± 0.75 mm) versus unmolded (2.34 ± 0.68 mm), P < 0.08.ConclusionMolding a prostate before fixation provided a better alignment of internal structures within the prostate, but this did not reach statistical significance. Software-based morphing allowed for nearly complete overlap between the pathology slides and the MR images.

Treball desenvolupat dins el marc del programa 'European Project Semester'., This document is a report on the work for the project “Rotational Moulding Machine” between the period from March to June during the course 2013/2014 at the Ecole Nationale d’Ingénieurs de Tarbes (ENIT) as part of the European Project Semester (EPS). A team of three students from different countries worked together to do a project in the same language with the help of several supervisors. This team had the task to continue a project from the last EPS team who designed a Rotational Moulding Machine in Catia software. To achieve this goal it needed to learn the last project to continue the new project. Once the team had enough information about the machine, they used their knowledge and their skills as a designers and engineers to develop a final product and its mould evaluating the pros and cons of each design, until a final design into software program Catia V5. To project was completed in 100% more time is needed. Next EPS team based on the work of the last two teams will be finishing this project.

Soutěž na fontánu před Rudolfinum byla jednou z neprestižnějších uměleckých událostí na konci 19. století. Fontána však nebyla nikdy realizovaná a soutěž byla v proudu dějin téměř zapomenuta. Restaurátorská dokumentace podává zprávu o restaurování fragmentů návrhů na fontánu nalezených ve vile Stanislava Suchardy. Tyto fragmenty jsou jedinými známými dochovanými ze všech návrhů. Rodina Suchardů je pozoruhodná kontinuitou uměleckých a restaurátorských povolání, která byla zachovávána členy rodu už od konce 18. století. Tato činnost vrcholí sochařem a restaurátorem Vojtěchem Suchardou, ve kterém se spojila tvořivost a invence s citem pro historii díla., Competition for fontain in front of Rudolfinum was one of the most prestigious art events on the late 19th century. Fontain was never implemented and competition was olmost forgetten on the stream of history. Restoration documentation reports on the restoration of fragments of the fountain founded in the villa of Stanislav Sucharda. These fragments are only known extant pieces of all proposals. Family Sucharda is remarkable continuity and restoration of artistic professions, which was maintained family members since the end of the 18th century. This activity culminates sculptor and restorer Vojtech Sucharda, which brings together creativity and inventiveness with a sense of history of art., Ateliér restaurování kamene

The objective of this study was to evaluate the chemical parameters and urinary sediment changes before and after a soccer game. Seventeen players were selected from a selective universitary men´s soccer team (age 21,8 ± 1,38 years, weight 73,2 ± 11,8 kg, height 1,71 ± 0,07 m and BMI 24,7 ± 2.3 kg/m2). Chemical parameters of the urine (specific gravity, pH, leukocytes, nitrite, proteins, glucose, bodies ketones, urobilinogene, bilirubin and erythrocytes) and sediment (leukocytes, erythrocytes, crystals, epithelial cells, bacteria, casts, and mucine filaments) were determined. We found a significant increase of specific gravity before and after of competition (1,019 ± 0.005 vs 1,025 ± 0.004; p= 0,0001), pH (6,0 ± 0,91 vs 5,35 ± 0,60; p= 0,008) urinary and in presence of bilirubin (0% vs 41,2%; p= 0,01). In urinary sediment was found a significant rise in the presence of casts (0% vs 29,4%; p= 0,04) and mucin filaments (11,7% vs 64,7% p= 0,004). Although some changes were found in urinary parameters, these chances may have been influenced by an increase in renal reabsortion of water., El objetivo del presente estudio fue evaluar los cambios químicos y del sedimento urinario en un selectivo universitario antes y después de una competición de fútbol asociación. Para ello, se seleccionaron diecisiete jugadores de un selectivo universitario de fútbol varonil (edad 21,8 ± 1,38 años, peso 73,2 ± 11,8 kg, talla 1,71 ± 0,07 m e IMC 24,7± 2,3 kg/m2). A quienes se les determinaron los parámetros químicos de la orina (gravedad específica, pH, leucocitos, nitritos, proteína, glucosa, cetonas, urobilinógeno, bilirrubina y eritrocitos) y del sedimento urinario (leucocitos, eritrocitos, cristales, células epiteliales, bacterias, cilindros y filamento de mucina). Se encontró un aumento significativo en la gravedad específica al comparar el antes vs después de la competición (1,019 ± 0.005 vs 1,025 ± 0.004; p= 0,0001), el pH (6,0 ± 0,91 vs 5,35 ± 0,60; p= 0,008) y en la presencia de bilirrubina (0% vs 41,2%; p= 0,01). En el sedimento urinario se observó un aumento en la presencia de cilindros (0% vs 29,4%; p= 0,04) y de filamento de mucina (11,7% vs 64,7% p= 0,004). Aunque se encontraron cambios en algunos parámetros urinarios, estos cambios pudieron haber estado influenciados por un aumento en la reabsorción renal de líquidos.

Plastic bronchitis is not yet well understood. There have been less than 500 reported cases in adults worldwide. This patient presented with a one month history of productive sputum consisting of bronchial casts resulting in a diagnosis of plastic bronchitis. [West J Emerg Med. 2011;12(1):118-119.]

Farmers' perceptions of earthworm activities were studied in the transitional zone of Benin and linked to scientific explanations of earthworm casting activities. Earthworm activity was assessed in farmers' fields with three different cassava cultivars and in a field experiment with three different egusi melon species. The experiment included plots with cowpea and maize. The study also comprised group discussions and a survey with 91 individual farmers. All farmers were aware of earthworms, but there were significant gender differences in terms of perception of earthworms. The presence of earthworm casts is used by farmers as an indicator of soil fertility and of good conditions for crop growth. Cast production over a period of two months was highest in fields with maize, followed by cowpea, cassava and egusi melon. Farmers' ranking of earthworm abundance showed a pattern almost the opposite of our assessment, with cassava and egusi melon fields being ranked highest and those with maize and cowpea lowest. We suggest that farmer's criteria are context-dependent, with earthworm casting activity being relevant when judging whether a field can be intensively cropped again. Casts showed significantly higher plant nutrient contents than the topsoil. Nevertheless, the amount of nutrients recycled in casts is relatively low. Farmer involvement in the research activity increased their interest in earthworms

Práce studuje možnost přípravy umělých pískovců na bázi alkalicky aktivovaných pojiv (geopolymerů) pro účely restaurování kamenných památek. Cílem práce bylo porovnat vlastnosti různých geopolymerních systémů se třemi vybranými přírodními horninami, které jsou v Čechách běžným materiálem kamenných památek – pískovec z lokality Hořice, Mšené Lázně a Božanov. Celkem bylo testováno pět geopolymerních pojiv, které byly připraveny alkalickou aktivací metakaolinu. Jako plnivo byl použit křemičitý písek o distribuci zrn odpovídající zrnitosti přírodních hornin. U připravených směsí byly popsány zpracovatelské a uživatelské vlastnosti, po jejich vytvrdnutí byly zjištěny jejich mechanické a fyzikální charakteristiky. Směsi byly poté prakticky odzkoušeny pro různé aplikace a vystaveny podmínkám přirozeného stárnutí. Vlastnosti alkalicky aktivovaných směsí s různými typy plniv se svými mechanickými a fyzikálními vlastnostmi velmi podobají srovnávaným přírodním horninám. U všech směsí byla dosažena srovnatelná pevnost s přírodními horninami a mírně vyšší kapilární aktivita pro vodu. Problematická je pouze přítomnost vodorozpustných solí, které mohou značně omezit použití tohoto typu umělého kamene v restaurování, zvláště pak v exterierových podmínkách. Z hlediska zpracovatelských vlastností lze tyto směsi použít pro tvorbu výdusků a kopií., The overall goal of the bachelor thesis was the preparation of artificial sandstones on the basis of alkali-activated binders (geopolymers) and to study the possibility of their utilization in stone monuments restoration. The properties of artificially prepared sandstone mixtures were compared with the properties of the sandstone originating from Horice, Msene Lazne and Bozanov locality. These materials are the most common materials used in Bohemia stone monuments art. Five different geopolymeric binders prepared by alkaline activation of metakaoline were tested. The silicious sand with the similar grain size distribution as the natural stones was used as a filler. For each prepared mixture the production process was fully described and after hardening the mechanical and physical properties were measured and evaluated. Finally the mixtures were practically tested for different applications and the results were exposed to the conditions natural ageing. The mechanical and physical properties of the alkali-activated mixtures with various kinds of fillers greatly resemble the properties of natural stones. All mixtures showed comparable solidity with the natural stones and slightly higer capillary activity for water. Contrary to the good agreement of the physical and mechanical properties of the tested mixtures and natural stones, the utilization of the artificially prepared sandstones in exteriors can be strongly limited by the presence of water-soluble salts. However, under certain conditions the tested mixtures can be use for making casts and replicas.., Katedra humanitních věd FR, Dokončená práce s úspěšnou obhajobou
