Abstract:
Abstract In order to develop bioretention fillers with better phosphorus removal capacity, we built 12 bioretention columns with six kinds of modified fillers, and analyzed the operation effects of the columns under different conditions through field tests. Results show that adding water treatment residual has optimal removal rates for total phosphorus (TP) (median = 96.80%) and soluble reactive phosphorus (SRP) (median = 97.13%). The water reduction rates of the columns with improved fillers are 1.23–2.04 times that of the bioretention soil media column. The coconut chaff column has the best water storage capacity (median = 40.54%). Among the external factors affecting column operation, influent concentration of pollutants in urban surface runoff is the biggest influence factor on the removal efficiency of TP. However, there are no significant correlations between the removal efficiency of SRP and rainfall, influent concentration, and discharge ratio. The columns modified with medical stone, vermiculite, peat soil, medical stone + peat soil, green zeolite + peat soil all have good removal for phosphorus pollutant. After entering the columns, the contents of TP and SRP in most columns increased. The recommended fillers and the accumulation performance of phosphorus can help to improve purification effects in bioretention systems.

Abstract:
Abstract Several 0.53 mm (i.d.) fused-silica open tubular columns were evaluated for the gas-chromatographic determination of ethanol and other volatiles in blood by both headspace and liquid injection. These columns offer the advantages of fused-silica technology without requiring expensive modification of the instrument for capillary. Methyl silicone columns of various lengths and film thicknesses were examined and also a polyethylene glycol column. The merits of each column are discussed and relative retention times are given.

Abstract:
Abstract Isolation of catecholamines on prepacked gravity-fed ion-exchange columns in conjunction with liquid-chromatographic separation is occasionally subject to disturbances of unknown origin, especially after injection of H3BO3 eluates from the ion-exchange columns onto the chromatography column. Peak spreading, sometimes even peak splitting, has been observed in many laboratories--effects easily confused with those sometimes caused by voided columns or by impurities. To elucidate the origins of these interferences, we performed a combined voltammetric and chromatographic investigation. We show that complexation of the catechol group by borate ions and dissociation of those pH-labile complexes in the course of the chromatographic separation is the cause of those peak distortions. Addition of a small volume of diluted HCI to the borate eluates eliminates such interference and leads to reproducible, easily interpretable chromatographic separations.

Abstract:
Abstract We present a statistical method to quantify deviations from linearity for assays that veer from linear assay responses. Our procedure handles the common case of unequally spaced analyte levels and nonconstant variance and provides a least-squares estimate with a confidence interval for the amount of deviation from assay linearity at a specified analyte concentration. This estimate of assay bias due to nonlinearity goes beyond the NCCLS EP6 lack-of-fit test, which tests for only the presence of nonlinearity. Knowing that nonlinearity is present is insufficient; users need to know the magnitude of the bias caused by nonlinearity. Our method can also be used with multifactor designs that estimate other systematic assay effects such as drift and carryover, thus obviating the need for a separate protocol to assess linearity. The procedure is carried out by adding extra columns to the design matrix corresponding to the concentration level(s) of interest. The extra columns, which replace the quadratic column, are orthogonal to all other columns. We describe a general method of constructing the new columns, and illustrate the procedure with a manual ammonia assay example dataset from EP6.

Abstract:
Using three columns of different depths (1.10m, 8.40m and 10.40m), we investigated the possibility of Biomphalaria glabrata moving towards deep regions. In the 1.10m column, we noted that locomotion can occur in two manners: 1) when the foot is in contact with the substrate: a) sliding descent; b) sliding ascent; c) creeping descent; d) creeping ascent, 2) when the foot is not in contact with the substrate: a) sudden descent without emission of air bules; b) sudden descent with emission of air bules; c) sudden ascent. In the 8.40m column containing food on the bottom (experimental group), the snails remained longer at this depth when compared to those of the group which received no food (control). The sliding behavior was characteristic of locomotion occurring at 0 to 1m both in upward and downward directions. Creeping behavior was typical for the ascent of the snails that reached deeper levels. When the snails were creeping, the shell remained hanging as if it were heavier, a fact that may have been due to water entering the pulmonary chamber. In the 10.40m column, the snails slid downward to a depth of 4m or descended suddenly all the way to the bottom. Ascent occurred by creeping from the bottom to the surface. In the 8.40m and 10.40m columns, copulation, feeding and oviposition occurred at the deepest levels.

This work presents a scalable Column-Row-Parallel ASIC architecture for 3D wearable / portable medical ultrasound. It leverages programmable electronic addressing to achieve linear scaling for both hardware interconnection and software data acquisition. A 16x16 transceiver ASIC is fabricated and flip-chip bonded to a 16x16 capacitive micromachined ultrasonic transducer (CMUT) to demonstrate the compact, low-power front-end assembly. A 3D plane-wave coherent compounding algorithm is designed for fast volume rate (62.5 volume/s), high quality 3D ultrasonic imaging. An interleaved checker board pattern with I&Q excitations is also proposed for ultrasonic harmonic imaging, reducing transmitted second harmonic distortion by over 20dB, applicable to nonlinear transducers and circuits with arbitrary pulse shapes. Each transceiver circuit is element-matched to its CMUT element. The high voltage transmitter employs a 3-level pulse-shaping technique with charge recycling to enhance the power efficiency, requiring minimum off-chip components. Compared to traditional 2-level pulsers, 50% more acoustic power delivery is obtained with the same total power dissipation. The receiver is implemented with a transimpedance amplifier topology and achieves a lowest noise efficiency factor in the literature (2.1 compared to a previously reported lowest of 3.6, in unit of mPa - [square root sign]mW/Hz). A source follower stage is specially designed to combine the analog outputs of receivers in parallel, improving output SNR as parallelization increases and offering flexibility for imaging algorithm design. Lastly, fault-tolerance is incorporated into the transceiver to deal with faulty elements within the 2D MEMS transducer array, increasing yield for the system assembly.

Abstract:
Bakgrund: Balansförmågan är komplex och bygger på att flera förmågor samspelar väl för att vara fungerande. Smärta, rörelserädsla och tilltro till egen förmåga är variabler som enligt studier har en inverkan på en individs funktionsförmåga. Hur dessa variabler påverkar utfallet i ett balanstest, är fortfarande ett område med kunskapsluckor. Syfte: Undersöka eventuella samband mellan smärta, rörelserädsla, tilltro till egen förmåga och balans hos en grupp personer med muskuloskeletal smärta från columna vertebralis. Metod: Studien var en observationsstudie med korrelerande design. Studiegruppen bestod av 18 personer, 9 män och 9 kvinnor med medelåldern 32 år. Där samtliga hade muskuloskeletal smärta härledd från columna vertebralis och valdes ut via ett bekvämlighetsurval. Självskattad smärta, rörelserädsla och tilltro till egen förmåga studerades var för sig, i förhållande till uppmätt balans. Data samlades in genom Numerical Rating Scale-självskattningsformulär, Tampa Scale of Kinesiophobia och Mini-BESTest, varpå Spearman ́s rangkorrelationskoefficient applicerades för att analysera samband. Resultat: Inga signifikanta samband kunde påvisas mellan självskattad smärta och uppmätt balans, självskattad rörelserädsla och uppmätt balans respektive tilltro till egen förmåga (självskattad balans) och uppmätt balans. Konklusion: I den undersökta gruppen kunde inga samband påvisas mellan smärta, rörelserädsla, tilltro till egen förmåga och balans.
Background: Balance capacity is a complex notion. It relies upon several abilities interacting well with each other in order to be functioning. Pain, kinesiophobia and Self-Efficacy are factors that according to studies do have an impact on the individual ́s functional capacity. Although within the area of how such variables specifically affects a balance test there are still gaps of knowledge. Objective: Examine possible correlations between pain, kinesiophobia, Self-Efficacy and balance in a population of people with musculoskeletal pain from columna vertebralis. Methods: The study was one of correlating design. The study group consisted of 18 people, 9 men and 9 women with an average age of 32 years. All of them had musculoskeletal pain from columna vertebralis and were selected through a convenience sample. Self-assessed pain, kinesiophobia, Self- Efficacy were studied separately relative to measured balance. Data was collected through Numerical Rating Scale-self assesment questionaires, Tampa Scale of Kinesiophobia and Mini- BESTest, whereon Spearman's rank correlation was applied in order to analyse correlations. Results: No significant correlations were found between self-assessed pain and measured balance, self-assessed kinesiophobia and measured balance or Self-Efficacy (self-assessed balance) and measured balance. Conclusion: In the studied group no significant correlations between pain, balance and kinesiophobia could be detected.

Abstract:
Esta tesis se presenta como un compendio de publicaciones, y en ella se abordan diferentes estudios de caracterización de la dinámica de las articulaciones de la columna medial del pie (tobillo y articulaciones mediotarsiana y metatarsofalángica) con diferente índice postural. En primer lugar se analizan las diferencias entre pies normales, altamente pronados y altamente supinados mediante gráficos de evolución temporal de rotaciones y momentos articulares en los tres planos de movimiento. Asimismo, se proporcionan valores estadísticos para los parámetros descriptivos de dichas curvas, y a partir de ellos, para pies normales, se identifican patrones normales de marcha. Por otra parte, se identifican y comparan las sinergias cinemáticas y cinéticas en pies normales y altamente supinados, y se analizan las diferencias en sus evoluciones temporales. Finalmente, se estudia la rigidez articular dinámica a flexión durante la marcha en pies normales, altamente pronados y altamente supinados, identificando diferentes fases con rigidez aproximadamente constante. Se analiza la variabilidad de la rigidez en dichas fases, y en particular el efecto de la velocidad de marcha. Y se detallan las diferencias de rigidez dinámica entre los distintos tipos de pie.
This thesis is presented as a compendium of publications, and it consists of different characterization studies of the dynamics of the joints of the medial column of the foot (ankle, midtarsal and metatarsophalangeal joints) with different postural indexes. First, the differences between normal, highly pronated and highly supinated feet are analyzed looking at the plots of joint rotations and moments vs time, in the three planes of movement. Statistical values ​​are also provided for the descriptive parameters of these curves, and used afterwards to identify gait patterns for normal feet. On the other hand, kinematic and kinetic synergies are identified and compared in normal and highly supinated feet, and the differences in their temporal evolutions are analyzed. Finally, dynamic joint stiffness in the flexural plane is studied during gait in normal, highly pronated and highly supinated feet, having identified different phases with approximately constant stiffness. The variability of the stiffness in these phases, and in particular the effect of the walking speed, is also analyzed. And the differences of dynamic stiffness between the different types of foot are detailed.

Abstract:
The formation of a pelvic ileal reservoir or pouch for patients requiring a proctocolectomy for ulcerative colitis or familial adenomatous polyposis (FAP) has gained rapid favour over recent years. The operation has evolved by empiric practice with the progressive refinement of operative technique. There is still debate over whether to retain or remove the anal transitional zone (ATZ). This debate relates to concern about the neoplastic and inflammatory potential of diseased mucosa if retained in the anal canal. Similarly the chronic inflammatory changes observed in ileal pouch mucosa have raised the possibility that neoplasia may be a long term consequence of forming the ileum into a pouch. This thesis investigates these issues. The work begins with a review of the literature on the ATZ and its importance in restorative proctocolectomy. Following this a detailed study of the micro anatomy of the anal canal is carried out on 28 anal canals. The median span of the ATZ was found to be only 4.5 millimetres and it contains almost no columnar epithelium. However an important area termed the columnar cuff was identified. In a patient who does not have a mucosectomy, the columnar cuff constitutes a span of diseased Columnar epithelium extending over 1 5 to 2.5 cm in the upper anal canal. Long term concerns need to focus on the columnar cuff rather than the ATZ. The columnar cuff and ATZ in 113 patients with an ileal pouch has been studied. These patients had an examination with the intention of biopsying the anal canal and ileal pouch to study the ATZ and columnar cuff. It was possible to obtain a successful biopsy of the columnar cuff in 72% of cases. The technique of staining for the small bowel brush border enzyme sucrase isomaltase has been developed and shown to reliably distinguish between pouch mucosa with villous atrophy and columnar cuff mucosa. The same group of patients was followed over a 2.5 year period and 9% were shown to have symptomatic ‘cuffitis’. A histological scoring system is described and a diagnostic triad of symptoms, endoscopic inflammation and acute inflammation on histology is put forward as a way to diagnose cuffitis. The same 113 patients had columnar cuff biopsies examined for dysplasia and aneuploidy at a mean of 2.5 years after pouch formation and 10.1 years after the diagnosis of ulcerative colitis. No dysplasia was found but one patient had aneuploidy in the columnar cuff. The final part of the work focuses on investigating the risk of neoplasia in ileal pouches. This work draws on a large cohort of 1221 patients with an ileal pouch and selects out a potentially higher risk group for pouch neoplasia. 106 patients who had a pouch for ulcerative colitis were selected, including 34 with chronic pouchitis. In addition 33 patients who had a pouch for FAP were studied. In the ulcerative colitis group one patient was found to have low grade dysplasia and aneuploidy and a further two patients aneuploidy. The risk of neoplasia in an ileal pouch for ulcerative colitis appears low and chronic pouchitis was not identified as a particular risk factor. In contrast adenomatous polyps were found in the ileal pouch of 42% of patients with FAP. It appears that forming the terminal ileum into a reservoir promotes the formation of ileal polyps. In conclusion forming the ileum into a pelvic reservoir to maintain continence appears to be a safe procedure with medium term follow up. It will be important to continue to gather data to establish the natural history of an ileal pouch. In the interim a level of follow up and surveillance for some groups of patients may be wise.

Esta pesquisa consiste em uma coorte histórica onde são selecionados 60 pacientes submetidos a exames de ressonância magnética da coluna cervical, que apresentavam como indicação clínica a cervicobraquialgia. O objetivo do trabalho é identificar, nestes exames, sinais de doença degenerativa da coluna cervical, nos pacientes em investigação clínica de cervicobraquialgia. A coleta dos dados foi realizada na base de dados da Clínica Imagem Centro Diagnóstico® localizada em Florianópolis. Dos exames selecionados 47 (78,3%) pertencem a pacientes do sexo feminino e 13 (21,7%) a pacientes do sexo masculino, com idade média de 44,4 anos. Foram avaliados neste estudo, estreitamento do forame neural (presente em 70% dos exames, predominando na faixa etária entre 46 e 80 anos com 92,3%), alterações degenerativas nas articulações uncovertebrais (redução do espaço articular e presença de osteófitos) onde se observou porcentagem de 100% entre 46 e 80 anos. Foram avaliados ainda, desidratação discal, redução do espaço discal e protrusão disco-osteofitária, sendo que a porcentagem de exames que apresentaram desidratação discal foi bastante elevada (86,7%). Estas alterações foram mais freqüentes entre 46 e 80 anos e o espaço discal mais envolvido, C5-C6. A hérnia discal, diferente das outras alterações encontradas, foi mais freqüente na faixa etária entre 24-45 anos, achado similar ao observado na literatura. Pode-se concluir que nos exames de pacientes com cervicobraquialgia analisados, os sinais de doença degenerativa presentes são: estreitamento do forame neural, alterações degenerativas nas articulações uncovertebrais, desidratação discal, redução do espaço discal, protrusão disco-osteofitária e hérnia, achados já consagrados na literatura.

Abstract:
In this study, three different chromatographic column chemistries (C18, Pentafluorophenyl (PFP), Hydrophilic Interaction Chromatography (HILIC)) were compared under optimal conditions to determine which stationary performed best in the separation and detection of a mixture of opioids using LC-MS. Furthermore, these stationary phases were examined in three different column technologies – traditional silica, porous shell, and porous polymer (PRP). The PRP column had the best peak shape for all 13 opioids and dominated for later-eluting compounds. In terms of column reproducibility, the Hamilton C18 column had the lowest %RSD values. The Kinetex HILIC produced the most theoretical plates and best resolution for polar compounds as did the Hamilton C18 for nonpolar compounds. Finally, Kinetex PFP and Hamilton PRP both demonstrated themselves as viable alternatives to the C18 column chemistry for analysis of this drug class.

Abstract:
We propose a novel, high degree of freedom variable stiffness joint for use in a miniature snake-like robot for minimally invasive surgeries via granular jamming. By pulling granule filled membrane-columns under vacuum, the columns and joint stiffen as the granular matter begin to jam. In our experiments, we achieved a four-fold increase in stiffness, and the stiffness can be achieved while the columns are straight or bent. Current flexible manipulators in industrial and medical robotics have followed two dominating methods of actuation and stiffness control. The first method is the continuum manipulator, which utilizes tendons or rods to bend the manipulator in a continuous fashion. The second method is classified as the highly articulated robot, where the manipulator is comprised of multiple segments linked by motor-driven universal joints. Like the latter, our manipulator is highly articulated, however stiffness of each joint can be independently controlled by the granular jamming principle. This paper studies the effect of grain type and vacuum pressure for stiffness tuning. We found that granules with a matte surface were able to achieve higher stiffnesses, with a cube shape exhibiting the highest stiffness, but at the cost of high levels of hysteresis.

Abstract:
The current study is focused on the flow through offset, wall confined vertical inserts in a channel. The columns are intended to act as the thermal storage media, which continuously exchange heat with the channel fluid to regulate it thermally. These columns could, for example, be filled with a phase change material (PCM) for passive thermal regulation, or have hot or cold fluid pumped through them for active thermal regulation. The current study has two parts: (1) the flow characterization without heat transfer, and (2) flow characterization during thermal exchange with a PCM used for regulation of bulk fluid temperature. The work presented here is focused only on the first part of the study. The experiments were conducted in a narrow channel, with water as the working fluid. Two geometries of the vertical columns (circular and square) and two offset lengths were considered. For each configuration, experiments were conducted at Reynolds numbers of 20, 50 and 90 (based of the column’s characteristic length). Particle image velocimetry was used to measure the two-dimensional velocity field in a horizontal plane at multiple regions of interest along the length of the channel to characterize the flow passing over columns. The results indicate vortex shedding at the two higher Reynolds numbers. The generation, magnitude and decay rate of turbulent energy is shown to have an offset dependency at Re = 90, but a column shape dependency at Re = 50. The mean flow has a shape dependency due to the difference in separation point over the square and circular columns.

Abstract:
Satisfactory outcome of intraarticular distal humerus fractures depends on anatomic joint restoration and stable fracture fixation to allow early motion. Orthogonal constructs (medial plate on medial column and posterior plate on lateral column) and parallel constructs (medial plate on medial column and lateral plate on lateral column) have been proposed for fixation of these fractures. However, the optimal configuration remains controversial. There are no clinical studies comparing these constructs and existing biomechanical studies had methodological limitations and reported conflicting results.

Abstract:
Military pilots are subjected to high magnitude inertial loads applied to the head-neck complex during high-G maneuvers. Cervical spinal soft-tissue injuries have occurred in this population [1–3]. Acute injury rates were reported between 54 and 89%, most commonly resulting in muscle or neck pain. Early cervical spine degenerative changes were also identified for fighter pilots [4]. Because the neck muscles are responsible for maintaining head-neck stability, one study hypothesized that cervical injuries in aviators may result from insufficient neck muscle strength to support the head-neck complex during high-G maneuvers [5]. This hypothesis is supported by the finding that pilots participating in pre-injury neck strengthening exercises demonstrated fewer injuries [1]. Although clinical data on the subject are limited, female pilots may be more susceptible to neck injury due to more slender necks and cervical columns that may be less resistant to bending [6, 7]. Differences in neck muscle geometry, in terms of cross-sectional area and positioning, may also lead to differing injury rates. Previous investigations of neck muscle geometry using contemporary medical imaging modalities were conducted with subjects in supine position [8–11], which removes the axial loads of the head and superior cervical structures due to gravity and likely changes neck muscle geometry. To date, no study has outlined gender-dependent neck muscle geometry determined using MRI of subjects in upright, sitting posture. The present hypothesis was that significant gender differences exist in neck muscle geometry.

Abstract:
The author characterized the Ukrainian national values, national interests and national goals. It is emphasized that national values are conceptual, ideological bases, consolidating factors, important life guidelines on the way to effective protection of Ukraine from Russian aggression and building a democratic, united Ukrainian state. Author analyzes the functioning of the mass media in the context of educational propaganda of individual, social and state values, the dominant core of which are patriotism, human rights and freedoms, social justice, material and spiritual wealth of Ukrainians, natural resources, morality, peace, religiosity, benevolence, national security, constitutional order. These key national values are a strong moral and civic core, a life-giving element, a self-affirming synergy, which on the basis of homogeneity binds the current Ukrainian society with the ancestors and their centuries-old material and spiritual heritage. Attention is focused on the fact that the current problem of building the Ukrainian state and protecting it from the brutal Moscow invaders is directly dependent on the awareness of all citizens of the essence of national values, national interests, national goals and filling them with the meaning of life, charitable socio-political life. It is emphasized that the missionary vocation of journalists to orient readers and listeners to the meaningful choice of basic national values, on the basis of which Ukrainian citizens, regardless of nationality together they will overcome the external Moscow and internal aggression of the pro-Russian fifth column, achieve peace, return the Ukrainian territories seized by the Kremlin imperialists and, in agreement will build Ukrainian Ukraine.
