(De)colonization through topophilia: Marjorie Kinnan Rawlings’s life and work in Florida

(De)colonization Through Topophilia: Marjorie Kinnan Rawlings’s Life and Work in Florida attempts to reveal the author’s intimate connection to and mental growth through her place, namely the Cross Creek environs, and its subsequent effect on her writing. In 1928, Marjorie Kinnan Rawlings and her first husband Charles Rawlings came to Cross Creek, Florida. They bought the shabby farmhouse on Cross Creek Road, trying to be both, writers and farmers. However, while Charles Rawlings was unable to write in the backwoods of the Florida Interior, Rawlings found her literary voice and entered a symbiotic, reciprocal relationship with the natural world of the Cracker frontier. Her biographical preconditions – a childhood spent in the rural area of Rock Creek, outside of Washington D. C. - and a father who had instilled in her a sense of place or topophilia, enabled her to overcome severe marriage tensions and the hostile climate women writers faced during the Depression era. Nature as a helping ally and as an “undomesticated”(1) space/place is a recurrent motif throughout most of Rawlings’s Florida literature. At a time when writing the American landscape/documentary and the extraction of the self from texts was the prevalent literary genre, Marjorie Kinnan Rawlings inscribed herself into her texts. However, she knew that the American public was not yet ready for a ‘feminist revolt’, but was receptive of the longtime ‘inaudible’ voices from America’s regions, especially with regard to urban poverty and a homeward yearning during the Depression years. Fusing with the dynamic eco-consciousness of her Cracker friends and neighbors, Rawlings wrote in the literary category of regionalism enabling her to pursue three of her major aims: an individuated self, a self that assimilated with the ‘master narratives’ of her time and the recognition of the Florida Cracker and Scrub region. The first part of this dissertation briefly introduces the largely unknown and underestimated writer Marjorie Kinnan Rawlings, providing background information on her younger years, the relationship toward her family and other influential persons in her life. Furthermore, it takes a closer look at the literary category of regionalism and Rawlings’s use of ‘place’ in her writings. The second part is concerned with the ‘region’ itself, the state of Florida. It focuses on the natural peculiarities of the state’s Interior, the scrub and hammock land around her Cracker hamlet as well as the unique culture of the Florida Cracker. Part IV is concerned with the analysis of her four Florida books. The author is still widely related to the ever-popular novel The Yearling (1938). South Moon Under (1933) and Golden Apples (1935), her first two novels, have not been frequently republished and have subsequently fallen into oblivion. Cross Creek (1942), Rawlings’s last Florida book, however, has recently gained renewed popularity through its use in classes on nature writers and the non-fiction essay but it requires and is here re-evaluated as the author’s (relational) autobiography. The analysis through place is brought to completion in this work and seems to intentionally close the circle of Rawlings’s Florida writings. It exemplifies once more that detachment from place is impossible for Rawlings and that the intermingling of life and place in literature, is essential for the (re)creation of her identity. Cross Creek is therefore not only one of Rawlings’s greatest achievements; it is more importantly the key to understanding the author’s self and her fiction. Through the ‘natural’ interrelationship of place and self and by looking “mutually outward and inward,”(2) Marjorie Kinnan Rawlings finds her literary voice, a home and ‘a room of her own’ in which to write and come to consciousness. Her Florida literature is not only product but also medium and process in her assessment of her identity and self. _____________ (1) Alaimo, Stacy.

The special rights other than shares in cross-border mergers of limited liability companies within the European Union. A perspective from the Spanish Law

The present research aims to study the special rights other than shares in Spanish Law and the protection of their holders in cross-border mergers of limited liability companies within the European Union frame. Special rights other than shares are recognised as an independent legal category within legal systems of some EU Member States, such as Germany or Spain, through the implementation of the Third Directive 78/855/CEE concerning mergers of public limited liability companies. The above-cited Directive contains a special regime of protection for the holders of securities, other than shares, to which special rights are attached, consisting of being given rights in the acquiring company, at least equivalent to those they possessed in the company being acquired. This safeguard is to highlight the intimate connection between this type of rights and the company whose extinction determines the existence of those. Pursuant to the Directive 2005/56/CE on cross-border mergers of limited liability companies, each company taking part in these operations shall comply with the safeguards of members and third parties provided in their respective national law to which is subject. In this regard, the protection for holders of special rights other than shares shall be ruled by the domestic M&A regime. As far as Spanish Law are concerned, holders of these special rights are recognized a right of merger information, in the same terms as shareholders, as well as equal rights in the company resulting from the cross-border merger. However, these measures are not enough guarantee for a suitable protection, thus considering those holders of special rights as special creditors, sometimes it will be necessary to go to the general protection regime for creditors. In Spanish Law, it would involve the recognition of right to the merger opposition, whose exercise would prevent the operation was completed until ensuring equal rights.

Spinal cord injury: assessment of autonomic state-dependent control of cardiovascular system and body core temperature

Spinal cord injury (SCI) results not only in paralysis; but it is also associated with a range of autonomic dysregulation that can interfere with cardiovascular, bladder, bowel, temperature, and sexual function. The entity of the autonomic dysfunction is related to the level and severity of injury to descending autonomic (sympathetic) pathways. For many years there was limited awareness of these issues and the attention given to them by the scientific and medical community was scarce. Yet, even if a new system to document the impact of SCI on autonomic function has recently been proposed, the current standard of assessment of SCI (American Spinal Injury Association (ASIA) examination) evaluates motor and sensory pathways, but not severity of injury to autonomic pathways. Beside the severe impact on quality of life, autonomic dysfunction in persons with SCI is associated with increased risk of cardiovascular disease and mortality. Therefore, obtaining information regarding autonomic function in persons with SCI is pivotal and clinical examinations and laboratory evaluations to detect the presence of autonomic dysfunction and quantitate its severity are mandatory. Furthermore, previous studies demonstrated that there is an intimate relationship between the autonomic nervous system and sleep from anatomical, physiological, and neurochemical points of view. Although, even if previous epidemiological studies demonstrated that sleep problems are common in spinal cord injury (SCI), so far only limited polysomnographic (PSG) data are available. Finally, until now, circadian and state dependent autonomic regulation of blood pressure (BP), heart rate (HR) and body core temperature (BcT) were never assessed in SCI patients. Aim of the current study was to establish the association between the autonomic control of the cardiovascular function and thermoregulation, sleep parameters and increased cardiovascular risk in SCI patients.

Attualità del divieto assoluto di procreazione medicalmente assistita eterologa in Italia e prospettive di superamento

La presente ricerca si fonda su un’attenta ed approfondita analisi della normativa vigente in Italia in materia di procreazione medicalmente assistita (P.M.A.), con particolare riferimento al divieto assoluto di P.M.A. eterologa, di cui all’art. 4, comma 3, L. 19 febbraio 2004, n. 40, consentita invece – sia pure con la previsione di limitazioni differenti – nella quasi totalità dei paesi europei. Dopo aver esaminato la “questione etica” del ricorso alle tecniche di fecondazione assistita e le normative vigenti in Europa in materia di P.M.A. eterologa, il presente lavoro analizza i profili civilistici della L. n. 40/2004 ed i conseguenti dubbi interpretativi che la normativa italiana pone in materia di fecondazione eterologa, con specifico riguardo al consenso prestato dai coniugi o conviventi, al divieto di disconoscimento di paternità e di anonimato della madre ed, infine, al diritto del nato da fecondazione eterologa di conoscere le proprie origini biologiche. Ne consegue che, in una materia che coinvolge la sfera più intima e personale della vita privata e familiare, quale quella della P.M.A., il legislatore avrebbe dovuto intervenire con misura, individuando soluzioni ragionevoli ed equilibrate nel rispetto della pluralità di etiche contrapposte ed interessi in conflitto. Attraverso una capillare analisi della recente giurisprudenza nazionale ed europea, la presente ricerca mira, dunque, a valutare possibili prospettive di superamento del divieto assoluto di P.M.A. eterologa previsto dalla L. n. 40/2004. I risultati a cui la presente indagine ha consentito di pervenire dimostrano quanto sia opportuna l’adozione in Italia di un “modello liberale”, in cui sia lecita anche la fecondazione eterologa (con la previsione di limiti e condizioni volti a tutelare primariamente il superiore interesse del nascituro), onde consentire l’adeguamento al nuovo concetto di “genitorialità” ormai prevalente e l’arresto del cd. “turismo procreativo”.

Uno studio sulla responsabilita' da reato degli enti

Il lavoro è suddiviso in due sezioni, che si compongono rispettivamente di tre e due capitoli. La prima sezione è dedicata all'esame dei principi fondamentali e della "parte generale" della disciplina della responsabilità amministrativa degli enti: il primo capitolo si concentra sull'evoluzione storica del principio Societas delinquere non potest nell'ordinamento giuridico italiano, prodromica all'analisi della natura della responsabilità amministrativa dipendente da reato degli enti. svolta nel secondo capitolo. Nel terzo capitolo della prima sezione si affronta la disciplina di "parte generale" del decreto 231, evidenziando, in particolare. i principi fondamentali che caratterizzano questo paradigma di illecito. La seconda sezione affronta invece due degli aspetti maggiormente problematici della "parte speciale" del decreto, ovvero la responsabilità degli enti per i delitti di omicidio e lesioni colpose (ai quali è dedicato il primo capitolo) e quella derivante dalla commissione di reati associativi (ai quali è dedicato il secondo capitolo).

Dynamic development of hydrofractures

Natürliche hydraulische Bruchbildung ist in allen Bereichen der Erdkruste ein wichtiger und stark verbreiteter Prozess. Sie beeinflusst die effektive Permeabilität und Fluidtransport auf mehreren Größenordnungen, indem sie hydraulische Konnektivität bewirkt. Der Prozess der Bruchbildung ist sowohl sehr dynamisch als auch hoch komplex. Die Dynamik stammt von der starken Wechselwirkung tektonischer und hydraulischer Prozesse, während sich die Komplexität aus der potentiellen Abhängigkeit der poroelastischen Eigenschaften von Fluiddruck und Bruchbildung ergibt. Die Bildung hydraulischer Brüche besteht aus drei Phasen: 1) Nukleation, 2) zeitabhängiges quasi-statisches Wachstum so lange der Fluiddruck die Zugfestigkeit des Gesteins übersteigt, und 3) in heterogenen Gesteinen der Einfluss von Lagen unterschiedlicher mechanischer oder sedimentärer Eigenschaften auf die Bruchausbreitung. Auch die mechanische Heterogenität, die durch präexistierende Brüche und Gesteinsdeformation erzeugt wird, hat großen Einfluß auf den Wachstumsverlauf. Die Richtung der Bruchausbreitung wird entweder durch die Verbindung von Diskontinuitäten mit geringer Zugfestigkeit im Bereich vor der Bruchfront bestimmt, oder die Bruchausbreitung kann enden, wenn der Bruch auf Diskontinuitäten mit hoher Festigkeit trifft. Durch diese Wechselwirkungen entsteht ein Kluftnetzwerk mit komplexer Geometrie, das die lokale Deformationsgeschichte und die Dynamik der unterliegenden physikalischen Prozesse reflektiert. rnrnNatürliche hydraulische Bruchbildung hat wesentliche Implikationen für akademische und kommerzielle Fragestellungen in verschiedenen Feldern der Geowissenschaften. Seit den 50er Jahren wird hydraulisches Fracturing eingesetzt, um die Permeabilität von Gas und Öllagerstätten zu erhöhen. Geländebeobachtungen, Isotopenstudien, Laborexperimente und numerische Analysen bestätigen die entscheidende Rolle des Fluiddruckgefälles in Verbindung mit poroelastischen Effekten für den lokalen Spannungszustand und für die Bedingungen, unter denen sich hydraulische Brüche bilden und ausbreiten. Die meisten numerischen hydromechanischen Modelle nehmen für die Kopplung zwischen Fluid und propagierenden Brüchen vordefinierte Bruchgeometrien mit konstantem Fluiddruck an, um das Problem rechnerisch eingrenzen zu können. Da natürliche Gesteine kaum so einfach strukturiert sind, sind diese Modelle generell nicht sonderlich effektiv in der Analyse dieses komplexen Prozesses. Insbesondere unterschätzen sie die Rückkopplung von poroelastischen Effekten und gekoppelte Fluid-Festgestein Prozesse, d.h. die Entwicklung des Porendrucks in Abhängigkeit vom Gesteinsversagen und umgekehrt.rnrnIn dieser Arbeit wird ein zweidimensionales gekoppeltes poro-elasto-plastisches Computer-Model für die qualitative und zum Teil auch quantitativ Analyse der Rolle lokalisierter oder homogen verteilter Fluiddrücke auf die dynamische Ausbreitung von hydraulischen Brüchen und die zeitgleiche Evolution der effektiven Permeabilität entwickelt. Das Programm ist rechnerisch effizient, indem es die Fluiddynamik mittels einer Druckdiffusions-Gleichung nach Darcy ohne redundante Komponenten beschreibt. Es berücksichtigt auch die Biot-Kompressibilität poröser Gesteine, die implementiert wurde um die Kontrollparameter in der Mechanik hydraulischer Bruchbildung in verschiedenen geologischen Szenarien mit homogenen und heterogenen Sedimentären Abfolgen zu bestimmen. Als Resultat ergibt sich, dass der Fluiddruck-Gradient in geschlossenen Systemen lokal zu Störungen des homogenen Spannungsfeldes führen. Abhängig von den Randbedingungen können sich diese Störungen eine Neuausrichtung der Bruchausbreitung zur Folge haben kann. Durch den Effekt auf den lokalen Spannungszustand können hohe Druckgradienten auch schichtparallele Bruchbildung oder Schlupf in nicht-entwässerten heterogenen Medien erzeugen. Ein Beispiel von besonderer Bedeutung ist die Evolution von Akkretionskeilen, wo die große Dynamik der tektonischen Aktivität zusammen mit extremen Porendrücken lokal starke Störungen des Spannungsfeldes erzeugt, die eine hoch-komplexe strukturelle Entwicklung inklusive vertikaler und horizontaler hydraulischer Bruch-Netzwerke bewirkt. Die Transport-Eigenschaften der Gesteine werden stark durch die Dynamik in der Entwicklung lokaler Permeabilitäten durch Dehnungsbrüche und Störungen bestimmt. Möglicherweise besteht ein enger Zusammenhang zwischen der Bildung von Grabenstrukturen und großmaßstäblicher Fluid-Migration. rnrnDie Konsistenz zwischen den Resultaten der Simulationen und vorhergehender experimenteller Untersuchungen deutet darauf hin, dass das beschriebene numerische Verfahren zur qualitativen Analyse hydraulischer Brüche gut geeignet ist. Das Schema hat auch Nachteile wenn es um die quantitative Analyse des Fluidflusses durch induzierte Bruchflächen in deformierten Gesteinen geht. Es empfiehlt sich zudem, das vorgestellte numerische Schema um die Kopplung mit thermo-chemischen Prozessen zu erweitern, um dynamische Probleme im Zusammenhang mit dem Wachstum von Kluftfüllungen in hydraulischen Brüchen zu untersuchen.

Oligodendroglial exosomes in glia to neuron signaling

In the CNS, myelinating oligodendrocytes and axons form a functional unit based on intimate cell-cell interactions. In addition to axonal insulation serving to increase the conduction velocity of electrical impulses, oligodendrocytes provide trophic support to neurons essential for the long-term functional integrity of axons. The glial signals maintaining axonal functions are just at the beginning to become uncovered. Yet, their determination is highly relevant for all types of demyelinating diseases, where lack of glial support significantly contributes to pathology. rnThe present PhD thesis uncovers exosomes as a novel signaling entity in the CNS by which cargo can be transferred from oligodendrocytes to neurons. Exosomes are small membranous vesicles of endocytic origin, which are released by almost every cell type and have been implicated in intercellular communication. Oligodendrocytes secrete exosomes containing a distinct set of proteins as well as mRNA and microRNA. Intriguingly, oligodendroglial exosome release is stimulated by the neurotransmitter glutamate indicating that neuronal electrical activity controls glial exosome release. In this study, the role of exosomes in neuron-glia communication and their implications on glial support was examined. Cortical neurons internalized and accumulated oligodendroglial exosomes in the neuronal cell soma in a time-dependent manner. Moreover, uptake occurred likewise at the somatodendritic and axonal compartment of the neurons via dynamin and clathrin dependent endocytosis. Intriguingly, neuronal internalization of exosomes resulted in functional retrieval of exosomal cargo in vitro and in vivo upon stereotactic injection of Cre recombinase bearing exosomes. Functional recovery of Cre recombinase from transferred exosomes was indicated by acquired reporter recombination in the target cell. Electrophysiological analysis showed an increased firing rate in neurons exposed to oligodendroglial exosomes. Moreover, microarray analysis revealed differentially expressed genes after exosome treatment, indicating functional implications on neuronal gene expression and activity. rnTaken together, the results of this PhD thesis represent a proof of principle for exosome transmission from oligodendrocytes to neurons suggesting a new route of horizontal transfer in the CNS.rn

Preparation and functional characterisation of recombinant silicatein-alpha from the sponge Suberites domuncula

The marine world is an immense source of biodiversity that provides substances with striking potentials in medicinal chemistry and biotechnology. Sponges (Porifera) are marine animals that represent the most impressive example of organisms possessing the ability to metabolise silica through a family of enzymes known as silicateins. Complex skeletal structures (spicules) made of pure biogenic silica (biosilica) are produced under physiological conditions. Biosilica is a natural material comprising inorganic and organic components with unique mechanical, optical, and physico-chemical properties, including promising potential to be used for development of therapeutic agents in regenerative medicine. Unravelling the intimate physiological mechanisms occurring in sponges during the construction of their siliceous spicules is an on-going project, and several questions have been addressed by the studies proposed by our working group. In this doctoral work, the recombinant DNA technology is exploited for functional and structural characterisation of silicatein. Its precursors are produced as fusion proteins with a chaperone tag (named TF-Ps), and a robust method for the overexpression of native soluble proteins in high concentrations has been developed. In addition, it is observed and proven experimentally that the maturation of silicatein is an autocatalytic event that: (i) can be modulated by rational use of protease inhibitors; (ii) is influenced by the temperature of the environment; (iii) only slightly depends on the pH. In the same experimental framework, observations on the dynamics in the maturation of silicateins allow a better understanding of how the axial filaments form during the early stages of spicule construction. In addition, the definition of new distinct properties of silicatein (termed “structure-guiding” and “structure-forming”) is introduced. By homology models and through comparisons with similar proteins (the cathepsins), domains with significant surface hydrophobicity are identified as potential self-assembly mediators. Moreover, a high-throughput screening showed that TF-Ps could generate crystals under certain conditions, becoming promising for further structural studies. With the goal of optimise the properties of the recombinant silicatein, implementation of new production systems are tried for the first time. Success in the expression of silicatein-type proteins in insect and yeast cells, constitute a promising basis for further development, towards the establishment of an efficient method for the production of a high-value pure and soluble protein.

A case of homicidal intraoral gunshot and review of the literature

Determination of the manner of death in case of intraoral firearm wounds can be a challenge, especially if the circumstances of the incident are unclear and crime scene investigation is inadequate. It is a well-known fact that the mouth is one of the selected sites for suicide with firearms. Homicidal shooting through the mouth is said to be rare, but does occur, and can be mistaken for a suicide. For discrimination between suicide and homicide in cases of intraoral firearm wounds, some useful points are the site of entry wound, the direction of the internal bullet path, the range of fire and the circumstances of death. We demonstrate these points in a case of a homicidal gunshot to the mouth assessed by both classical autopsy and post-mortem CT (PMCT).

3D bloodstain pattern analysis: ballistic reconstruction of the trajectories of blood drops and determination of the centres of origin of the bloodstains

For crime scene investigation in cases of homicide, the pattern of bloodstains at the incident site is of critical importance. The morphology of the bloodstain pattern serves to determine the approximate blood source locations, the minimum number of blows and the positioning of the victim. In the present work, the benefits of the three-dimensional bloodstain pattern analysis, including the ballistic approximation of the trajectories of the blood drops, will be demonstrated using two illustrative cases. The crime scenes were documented in 3D, using the non-contact methods digital photogrammetry, tachymetry and laser scanning. Accurate, true-to-scale 3D models of the crime scenes, including the bloodstain pattern and the traces, were created. For the determination of the areas of origin of the bloodstain pattern, the trajectories of up to 200 well-defined bloodstains were analysed in CAD and photogrammetry software. The ballistic determination of the trajectories was performed using ballistics software. The advantages of this method are the short preparation time on site, the non-contact measurement of the bloodstains and the high accuracy of the bloodstain analysis. It should be expected that this method delivers accurate results regarding the number and position of the areas of origin of bloodstains, in particular the vertical component is determined more precisely than using conventional methods. In both cases relevant forensic conclusions regarding the course of events were enabled by the ballistic bloodstain pattern analysis.

Virtopsy: CT and MR imaging of a fatal head injury caused by a hatchet: A case report

Hatchet blows to the human skull often cause fatal injuries. We present a case of homicide by hatchet blow that underwent CT, MRI, and autopsy examination. Skull fragmentation, fracture lines, and brain injuries were demonstrated prior to autopsy. Many of the hatchet-specific characteristics (flaking, crushing, shattering, and fracture lines) described in literature were observed in the post-mortem imaging of this case.

Coals

I decided to write an honors thesis to exercise and develop my abilities as a writer. I explored a number of different characters, narrative styles, and tones in order to discover my strengths and push my comfort level and boundaries. I attempted to place myself in the minds of a wide range of characters, and to expose intimate aspects of their thoughts and personalities to my readers.

Shading Silhouettes of Smaller Ones

I am truly honored to have been given the amazing opportunity to create this original piece, this powerful journey through memory and emotive exploration of the loss of childhood. How do we feel about the loss of our child-self? Could we ever get them back? How long, how deep would one have to dig in the graveyards, the playgrounds of memory, to uncover what was buried there... to un-erase what waserased? shading silhouettes of smaller ones will ultimately encourage a reconnection with the Inner Child hidden inside all of us, as well as an intimate awareness of the adult version of the self by looking back to the smaller ones. The main inspiration for this piece is then of course, Inner Child Work. Most people may not be familiar with this therapeutic exploration of childhood... It wasimportant to me then, to present this concept in an imaginative, theatrical way, as a gift to you - a comprehensive and intensely moving gift. Speaking from experience, working on my Inner Child - my little Bianca - has been the most painful, frightening, yetrewarding and powerful experience within my personal life. Some people spend their entire lives trying to love themselves, to prove themselves, or be accepted. Some are too afraid to look back to where it all began. The characters within this piece will face thatfear... in a regression from the complexities of adulthood to the confusion of adolescence, all the way back to the wonder and bliss of childhood. They will reveal memories, of both joy and pain, love and abandonment, journeying backwards through time - through memory - through a playground - back to the beginning... We will enter a world where a push of a merry-go-round spins us to games of Truth or Dare after a high school dance at 16 - or the slam of a metal fence reminds us of the door Dad slammed in our face at 9 - where the sound of chain links swings us back to scrapping our knee by the sandbox at 5 This piece will attempt to connect everyone, both cast and audience, through a universal understanding and discussion of what it means to grow up, as well as a discovery of WHY we are the way we are - how experiences or relationships from our childhood have shaped our adult lives. We will attempt to challenge your honesty and nerve by inviting you to ask questions of yourselves, your past - to remember what it's like to have the innocence and hope of a child, to engage with and discover your Inner Child, to realize when or why you left them behind, and if you want to this magical part of yourself. It is my hope that you will join us in a collective journey - gather the courage to dig up the little kid you buried so long ago...* The creation, design, choreography, and direction for shading silhouettes of smaller ones mark the culminating experience of a year-long independent study in Theatre.

Disclosing Sexual Assault Victimization to Others

Previous research has demonstrated that victims of sexual assault disclose their assaults most frequently to members of their intimate social circle. Unfortunately, some friends and family members give support in ways that are perceived as unhelpful by victims. The present study found that victims' reports and non-victims' expectations of positive support after disclosure differed significantly. These results indicate that significant efforts are needed to change the campus culture by increasing support for sexual assault victims.

Solid-State Compatibilization of Immiscible Polymer Blends: Cryogenic Milling and Solid-State Shear Pulverization

The blending of common polymers allows for the rapid and facile synthesis of new materials with highly tunable properties at a fraction of the costs of new monomer development and synthesis. Most blends of polymers, however, are completely immiscible and separate into distinct phases with minimal phase interaction, severelydegrading the performance of the material. Cross-phase interactions and property enhancement can be achieved with these blends through reactive processing or compatibilizer addition. A new class of blend compatibilization relies on the mechanochemical reactions between polymer chains via solid-state, high energy processing. Two contrasting mechanochemical processing techniques are explored in this thesis: cryogenic milling and solid-state shear pulverization (SSSP). Cryogenic milling is a batch process where a milling rod rapidly impacts the blend sample while submerged within a bath of liquid nitrogen. In contrast, SSSP is a continuous process where blend components are subjected to high shear and compressive forces while progressing down a chilled twin-screw barrel. In the cryogenic milling study, through the application of a synthesized labeledpolymer, in situ formation of copolymers was observed for the first time. The microstructures of polystyrene/high-density polyethylene (PS/HDPE) blends fabricated via cryomilling followed by intimate melt-state mixing and static annealing were found to be morphologically stable over time. PS/HDPE blends fabricated via SSSP also showed compatibilization by way of ideal blend morphology through growth mechanisms with slightly different behavior compared to the cryomilled blends. The new Bucknell University SSSP instrument was carefully analyzed and optimized to produce compatibilized polymer blends through a full-factorial experiment. Finally, blends of varying levels of compatibilization were subjected to common material tests to determine alternative means of measuring and quantifying compatibilization,
