To investigate and assess bone regeneration in sheep in combination with new implant materials classical histological staining methods as well as immunohistochemistry may provide additional information to standard radiographs or computer tomography. Available published data of bone defect regenerations in sheep often present none or sparely labeled histological images. Repeatedly, the exact location of the sample remains unclear, detail enlargements are missing and the labeling of different tissues or cells is absent. The aim of this article is to present an overview of sample preparation, staining methods and their benefits as well as a detailed histological description of bone regeneration in the sheep tibia. General histological staining methods like hematoxylin and eosin, Masson-Goldner trichrome, Movat’s pentachrome and alcian blue were used to define new bone formation within a sheep tibia critical size defect containing a polycaprolactone-co-lactide (PCL) scaffold implanted for 3 months (n = 4). Special attention was drawn to describe the bone healing patterns down to cell level. Additionally one histological quantification method and immunohistochemical staining methods are described.

Recidivism within the sexually violent predator (SVP) population has gained worldwide attention because of the lack of protection offered to the victims that may lead to loss of life. Behavioral theory suggests that accuracy of predictive behaviors based on empirical judgement is more reliable than that based on clinical judgement. The purpose of this research was to see whether three actuarial assessment tools, Static-99, PCL-R, and MnSOST-R, could predict recidivism and whether the combination of the three-increased predictive value in the Texas SVP population. As yet, the literature provides no evidence. The Texas Open Record System provided assessment scores and violations of 90 SVPs committed during fiscal years 2009-2013. Texas had 58.9% violated commitment laws within the SVP population of the civil commitment program. The scores on these three assessment tools were analyzed along with the violations using bivariate logistic regression. According to the results, Static-99, PCL-R, and MnSOST-R can, in combination, predict recidivism better than any tool by itself in the Texas SVP. However, individually, only the PCL-R approached significance as a predictor. This study could lead to positive social change in both the targeted treatment of labeled SVP and in the accuracy of predicting recidivism among SVPs. Therapists should use the three actuarial assessment tools when developing treatment plans, intervention techniques, and when adjusting supervision requirements to assist in both targeted treatment and to reduce the number of victims.

Additive manufacturing has grown considerably during the last couple of decades, whether it comes to the printing of metal structure or living cells. Additive manufacturing techniques relays on the successive addition of material to create the wanted structure. Among the diversity of these many printing techniques, electrohydrodynamic 3D-printing is of particular interest, as the technique has a promising outlook for high-resolution printing on the microscale. The technique is compatible with a myriad of thermoplastics, but its writing resolution is limited due to the inherent affect the manufacturing process has on the material. Electrostatic forces between already deposited fibres and the fibre in light affect the final position of printed fibre. This thesis evaluates the possibility to increase the writing resolution in melt electrohydrodynamic 3D printing by a closed-loop feedback system. Components were built and added to an already existing printing setup to implement in-situ measurements of the fibres position as well as active electrostatic guiding of the fibre. The setup consisted of a camera that determined the position of the fibre; the position was then used in a PID controller to calculate an appropriate potential. The potential was forwarded to a high voltage amplifier, connected to a steering electrode, mounted in the vicinity of the jet. The setup built for one-dimensional steering of the fibre improved the printing accuracy by ten times through suppressing the repulsive/attractive forces, where the process variable of the PID controller was measured. However, the precision decreased roughly four times as it was deposited on the substrate. The limitations of the system have been evaluated, and possible improvements for the two-dimensional control of the fibre are further discussed.

Il n'existe à l'heure actuelle pratiquement pas de copolymères greffés à fonctions cationiques et/ou amphotères présentant une dégradabilité intrinsèque. L'objectif de cette thèse est de générer des composés répondant à ces critères à partir d'une méthode de modification chimique par voie anionique de poly(e-caprolactone) (PCL). A cette fin, deux stratégies principales ont été suivies à partir d'un même intermédiaire réactionnel, un macropolycarbanion dérivé de PCL. La première est fondée sur l'emploi du macropolycabanion en tant qu'agent nucléophile qui réagit avec de petites molécules organiques électrophiles. Ces réactions de substitution ont permis l'obtention de copolymères à base PCL possédant entre 10 et 15% de motifs substitués par des groupes cationiques (ammonium, phosphonium), ou hydrosolubilisants (amine, acide carboxylique). Ces squelettes PCL fonctionnalisés peuvent être utilisés pour effectuer des post-modifications (réactions de couplages, dérivation de fonctions). La seconde stratégie utilise le macropolycarbanion en tant que macroamorceur de polymérisation anionique. Ce type de réaction a été appliqué à des dérivés vinyliques (4-VP, N-VP), des dérivés acryliques (DMAEM, MAPEG), des dérivés acrylamides (DMA, DMAPMA) et des dérivés cycliques (NCA d'acides a-aminés) ce qui a permis d'obtenir des copolymères greffés hydrosolubles à chaîne principale PCL. Ces composés ont des structures partiellement dégradables et forment en solution aqueuse des objets de dimensions nanométriques. Enfin, l'utilisation d'un dérivé polyiodé de PCL en tant que macro-polyagent de transfert est abordée ce qui constitue une nouvelle méthode de polymérisation radicalaire contrôlée par transfert dégénératif d'iode permettant l'obtention de structures greffées.

High risk offenders are a complex and heterogeneous group of offenders about whom researchers, clinicians, and society still know relatively little. In response to the paucity of information that is specifically applicable to high risk offenders, the present study examined RCMP Integrated Sexual Predator Intelligence Network (ISPIN) data to investigate the relationship between sexual paraphilias, sexual fantasy, and psychopathy among 139 of the highest risk sexual offenders in British Columbia. The sample included 41 child molesters, 42 rapists, 18 rapist/molesters, 30 mixed offenders, and 6 “other” sexual offenders. The majority of offenders in this sample were diagnosed with one primary paraphilia (67%). Data analysis revealed significant differences between offender types for criminal history variables including past sexual and nonsexual convictions, number of victims, and age of offending onset. For example, offenders who victimized children (i.e., exclusive child molesters & rapist/molesters) had a greater number of past sexual convictions than did offenders who victimized adults exclusively. Further, there were significant differences between offender types for paraphilia diagnoses, sexual fantasy themes, and levels of psychopathy. For example, exclusive child molesters were significantly more likely to receive a paraphilia diagnosis, were more likely to report having sexual fantasies, and had lower Psychopathy Checklist Revised (PCL-R) scores than other offender types. Results from the current study will serve to facilitate a more refined and informed understanding of sexual offending behaviour, with important implications for future research, assessment, and treatment issues, as well as law enforcement practices when working with high risk sexual offenders.

This work describes the issue of tabletop object detection in point cloud. Point cloud is recorded with Kinect sensor. Designed solution uses algorithm RANSAC for plane detection, algorithm Euclidean clustering for segmentation and ICP algorithm for object detection. Algorithm ICP is modified and mainly it can detect rotational symetric objects and objects without any transformation against it's models. The final package is build on platform ROS. The achieved results with own dataset are good despite of the limited functionality of the detector.
