Abstract:
Abstract One of the approaches for solving challenges related to foundations, open cut excavations, landslides, rock slopes, fractured rocks and tunnelling is enhancement of soil via grouting. Two main components of soil enhancement are reduced permeability and increase in strength. To overcome reduced strength and permeability in soils and rock fissures, it has always depended on cement and lime treatment. To replace cement and lime, chemical and ultra-fine cementitious grouts are often employed to break through highly fissured rocks or fine sands. This document gives a censorious evaluation of chosen studies that used unconventional cementitious grouts in order to assist practicing engineers and promote best practice. In sand and cohesive soils, sodium silicate, colloidal silica, metakaolin, silica fume, fly ash, resins, polymers, and microfine substitutes were evaluated as grouting material. The intent of the article is to procure effective data for consultants and contractors who will be building injection works that use non-cementitious fluids in the future.

Abstract:
The most important purpose of cementing boreholes is to counteract the inflow of deep-seated waters into productive levels of oil and gas-bearing rocks. The increasing requirements regarding the properties of cement grout and cement stone enforces the search for unconventional solutions and materials that will provide a resolved improvement in their properties and resistance to temperature and chemical factors in difficult geological and reservoir conditions. Therefore, the number of binding materials that have been improved by various types of structures is growing rapidly. Materials with the properties needed to meet the above challenges are close to the technology of nanomaterials, which are still used in the oil industry to a very small extent. The comparative analysis conducted by the author showed that using appropriate amounts of SiO2 nanoparticles it will be possible to design a cement paste with good rheological parameters, high strength and, at the same time, characterized by low filtration.

Abstract:
Unconventional Collagens Types VI, VII, VIII, IX, X, XIV, XVI and XIX by S. Ricard-Blum, B. Dublet and M. van der Rest Oxford University Press (2000) pp.155. ISBN 0–19-850545-0 35.00 This thoroughly researched monograph in Oxford University Press's ‘Protein Profile Series’ reviews substantially all the significant literature on this interesting and highly important group of proteins. The authors use the term ‘Unconventional Collagens’ for the collagens of higher vertebrate connective tissues which do not, of themselves, form classical fibrils with a 68 nm banding pattern. The authors chose to omit type IV collagen as this, they claim, would have almost doubled the size of the volume. The monograph represents a very considerable achievement in three respects. Firstly it comprehensively reviews the literature on the sequence, structure, expression, post-translational modification, genetics, physiological function and pathology of each separate unconventional collagen. The thoroughness of this review is indicated by the fact that the bibliography contains no fewer than 1196 references. Secondly, the monograph identifies the modular domain structure for each collagen, clearly demonstrating that these proteins are block co-polymers mainly derived in evolution from a small number of ancestral genes. Thirdly, it starts to identify the way in which the different modules of these sticky molecules interact with each other and with other connective tissue components. This is an important start if we are to understand their vital role in the self-assembly processes which occur in embryology, tissue repair and the major degenerative and collagen gene diseases The clearly written and well set out text is supported by excellent micrographs of rotary shadowed molecules and molecular aggregates and a wealth of diagrams and tables. The book has, in my view, three minor shortcomings: a short summary chapter on type IV would enable the non-specialist reader to relate this collagen to the other non-conventional collagens. Concise summaries at the ends of each chapter would orient newcomers to the field. More significantly, apart from the brief introduction, the book lacks an overall synthesis which pulls together the findings of the separate chapters. These slight limitations aside, this book is essential reading for those engaged in connective tissue research and will do much to stimulate further activity in this area. It will also be of considerable interest to tissue engineers, pathologists and embryologists.

Abstract:
OBJECTIVE: There have been many studies investigating paraphilias and sexual compulsion, but thus far little data about prevalence of unusual sexual practices that are subthreshold for these diagnoses. The associations between unconventional sexual behavior and sociodemographic and health parameters were investigated. METHOD: A cross-sectional study of 7,022 individuals (45.4% of women) was carried out using a selfadministered questionnaire that compared individuals carrying at least one reference of unconventional sexual behavior (group 1) with individuals without such reference (group 2). RESULTS: Women's mean age was 35.0 vs. 35.9 years (p < 0.05) and men's mean age was 36.5 vs. 37.8 years (p < 0.05) being lower in group 1 than in group 2, respectively. More men (52.3%) than women (30.4%) (p < 0.001) presented unconventional sexual behavior. Fetishism (13.4%) and voyeuristic behavior (13.0%) were more frequent. Unconventional sexual behavior was associated with male gender, single or separated marital status, black or mulatto race, elementary and high school educational level, history of posttraumatic stress disorder treatment, alcohol dependence, emergency contraception, difficulty at the beginning of sexual life, sexual violence, bisexuality, and performance of anal or oral intercourse. CONCLUSION: Unconventional sexual behaviors are important because they are associated with poorer health status and lower educational levels.

Abstract:
Backgraund. Pancreatoduodenal resection (PDR) is the only radical treatment for malignant tumors of the periampullary zone. The development of postoperative pancreatic fistula (POPF) is the most common complication of PDR. The main risk factors for the development of POPF are the narrow main pancreatic duct and the soft, "juicy" pancreatic parenchyma. Thus, it is the stage of formation of a pancretodigestive anastomosis that is of decisive importance for the course of the postoperative period.The aim of the study was to improve immediate surgical treatment outcomes of patients suffering from oncological diseases of the periampullary zone with a soft pancreas and a narrow pancreatic duct.Methods. A novel method to form terminolateral reservoir invagination pancreatojejunostomy has been developed and introduced into clinical practice. The results of treatment of 94 patients with tumors of the periampullary zone were analyzed. Based on preoperative radiological diagnosis and intraoperative findings, such factors of a high risk of POPF development as a soft pancreas and a narrow major pancreatic duct ( 3 mm) were detected in 23 patients (24.4%). In 11 patients who were treated in 2018-2019, a novel method of pancreato-jejunoanastomosis formation was applied. The comparison group consisted of 12 patients who received treatment in 2014-2017; a differentiated approach to the formation of a pancreatodigestive anastomosis was not applied.Results. In patients of the main group, there was a tendency to an increase in the proportion of pylorus-saving PDRs. The only statistically significant difference was the use of reservoir terminolateral pancreatojejunostomy at the reconstructive stage of surgery. Complicated postoperative course was observed in 7 (63.6%) patients of the main group and in all patients of the comparison group (p 0.05). There was also a decrease in the incidence of postoperative pancreatic fistulas from 66.6 to 18.2% (p 0.05) in the study group. Repeated surgery was required in 3 (27.2%) patients of the main group and 7 (58.3%) patients in the comparison group (p 0.05). The lethal outcome was recorded in 2 (18.2%) patients of the main group and in 3 (25%) in the comparison group (p 0.05).Conclusion. A soft, loose pancreas and a narrow main pancreatic duct are the most significant risk factors for complications in the postoperative period. Management of this condition requires a differentiated approach to the treatment option of pancreatodigestive anastomosis formation, depending on the characteristics of the pancreas of an individual patient. The proposed technique for the reservoir terminolateral pancreatojejunoanastomosis formation allowed statistically significantly reducing the incidence of complications from 100 to 63.6% and the incidence of postoperative pancreatic fistulas from 66.6 to 18.2% in high-risk patients..

Abstract:
Organic contaminants belonging to various classes (plasticizers, bisphenols, pesticides, PCBs, and PAHs,) were analyzed in samples of provola cheese produced from Friesian dairy cows fed with a conventional diet (group CTR), and an unconventional diet (group BIO) enriched with olive cake (OC). The results show that for most determined contaminants, the differences between the two diets were very slight, indicating that the contamination does not depend on the olive cake integrated in the unconventional diet. The results also indicate that the minimal contamination could result from environmental contamination or the production process. It can be concluded that unconventional provola is as safe for the consumer as conventional provola.

Abstract:
The PhD research activities are focused on ground improvement application. The objective is to study the permeation grouting technique in granular soils and to understand the hydro-mechanical properties that can be obtained using non-conventional injection materials. During the project it has been developed an injection apparatus and a monitoring system of the grouting process that is used to study the permeation process and to develop a theoretical, and then analytical and numerical approach. Furthermore, the injection apparatus is used to simulate the permeation of different injection materials in soils and to generate specimen for hydraulic and mechanical evaluations. The experimental set-up comprises of a polycarbonate extruded clear tube, 50 mm in inner diameter and variable length (with a maximum of 1.6 m), and two floating caps at the extremities with a double sealing system. Once it has been filled with a selected soil it is inserted in a rigid steel chassis and the hole injection system can support 100 bar injection pressure. To simulate the soil micro-mechanical behavior has been created a loading system, composed by a screw that can apply a confining pressure on the soil sample. The column is then instrumented: • two load cells to control the confining pressure; • five pressure transducers to control the imposed pressure; • two pressure switches to impose pressure to the fluid; • laser ranging distance sensors to measure the flow rate; • vision camera to detect fluid front advancement. The data from the sensors are collected by employing Arduino processors and all the results are elaborated and displayed in real time with a Labview platform software. Some of the sensors were properly calibrated after being installed and all the measurements and the injection apparatus are validated before starting the test. The injection apparatus has been used to test different conventional and non-conventional grout with different rheological properties: sodium silicate, acrylic resin, colloidal silica, cement and micro-cement grout. For some of the previous injection materials have been defined a rheological time-dependent law. All these tests have been used to understand the permeation phenomena and to define an analytical and numerical predictive model that could be valid for all the soil in all conditions. By using this approach and by knowing the soil hydraulic properties, related to a new geotechnical project, it should be possible to indicate to designers the type of grout, the injection parameters and the injection geometry for this specific ground improvement application. Finally, a hydro-mechanical investigation of the different injection materials has been performed, consisting of the following test: permeability, unconfined compressive strength, triaxial test and brasilian test. For each injection test it has been evaluated the difference mechanical behavior from the bottom to the top part of the column, resulting from a variable soil saturation during the permeation process, that, in a ground with a grout spherical propagation, can be related to the radial distance from the injection point. Furthermore, a mechanical comparison, in term of friction angle and cohesion, is performed for the different grout types and, for some of them, at different curing time.

Abstract:
The Karoo Basin of South Africa holds an estimated 906 billion to 11 trillion cubic meters of unconventional shale gas within the shales of the Whitehill and Collingham formations of the Ecca Group. Evaluation of this potential resource has been limited due to the lack of exploration and a scarcity of existing drill core data. In order to circumnavigate this problem this study was undertaken to evaluate the potential target horizons exposed in outcrops along the southern portion of the Karoo Basin, north of Grahamstown in the Eastern Cape Province. Detailed field logging was done on the exposed Whitehill and Collingham formations as well as a possible conventional sandstone (turbidite) reservoir, the Ripon Formation, along road cuttings of the Ecca Pass. Palaeocurrent data, jointing directions and fossil material were also documented. Samples were analysed for mineralogy, porosity, permeability, and total organic carbon content (TOC). The extensively weathered black shales of the Whitehill Formation contain a maximum TOC value of 0.9% and the Collingham Formation shales contain a maximum TOC value of 0.6%. The organic lithic arkose sandstones of the Ripon Formation are classified as ‘tight rock’ with an average porosity of 1% and an average permeability of 0.05 mD. The Whitehill Formation in the southern portion of the Karoo Basin has experienced organic matter loss due to low grade metamorphism as well as burial to extreme depths, thus reducing shale gas potential. The Ripon Formation is an unsuitable conventional reservoir along the southern basin boundary due to extensive cementation and filling of pore spaces.

Abstract:
The objective of this thesis is to reach theoretical understanding of the unusual relationship between charge-ordering and superconductivity in correlated-electron systems. The competition between these broken symmetries and magnetism in the cuprate high temperature superconductors has been extensively discussed, but exists also in many other correlated-electron superconductors, including quasi-two-dimensional organic charge-transfer solids. It has been suggested that the same attractive interaction is responsible for both charge-order and superconductivity. We propose that the specific interaction is the tendency in correlated-electron systems to form spin-singlet bonds, which is strongly enhanced at the commensurate carrier density p of ½ a charge carrier per site, characteristic of all superconducting charge-transfer solids. To probe superconductivity driven by electron correlations, a necessary condition is that electron-electron interactions enhance superconducting pair-pair correlations, relative to the non-interacting limit. We have performed state of the art numerical calculations on the two-dimensional Hubbard model on different triangular lattices, as well as other lattices corresponding to K-BEDT-TTF based organic charge transfer solids, for the complete range of carrier densities per site p (0 ≤ p ≤ 1). We have shown that pair-pair correlation for each cluster is enhanced by electron-electron interaction only for p ≃ 0.5, far away from the density range thought to be important for superconductivity. Although initial focus is on charge-transfer solids, the results of the research will impact the field of correlated electrons as a whole. We believe our calculations will provide fundamental and fresh insight to the theory of superconductivity in strongly correlated systems.

Abstract:
We studied the structural instabilities of one-dimensional (1D) and quasi-one-dimensional (Q1D) electron-phonon systems at low temperature through two models, SuSchrieffer-Heeger (SSH) and molecular crystal (CM) with and without spin. The phase diagrams are obtained using a Kadanoff-Wilson renormalization group approach (GR). For the 1D half-filled system the study of the frequency dependence of the electronic gap allowed us to connect continuously the two limits, adiabatic and non-adiabatic. The Peierls and Cooper channels interference and the quantum fluctuations reduce the gap. A regime change occurs when the frequency becomes of the order of mean field gap, marking a quantum-classical crossover that is the Kosterlitz-Thouless type. At this level, the effective coupling behaves in power law function on frequency. For the case with spin, a gapped Peierls state is maintained in the non-adiabatic limit, while for the case without spin, the system transits to ungapped disordered state, namely the Luttinger liquid stat (LL). For the SSH model without spin, the GR confirms the existence of a threshold phonon coupling beyond which the gap is restored. The study of the rigidities of the two models without spin allowed us to trace the main features of the LL state predicted by the bosonization method. The study of the Holstein-Hubbard model has allowed us not only to reproduce the phase diagrams already obtained by the Monte Carlo method, but to highlight two additional phases, namely, free fermions phase and the bond charge-density-wave phase. We have extended this study to the quarter-filled Q1D Peierls systems at finite temperature. Within the SSH model, an unconventional superconducting phase with spin singlet symmetry SS-s emerges at low temperature when the deviation to the perfect nesting of the Fermi surface is strong enough. Peierls-SS transition is characterized by the presence of a quantum critical point at low frequency and by a power law behavior of the transition temperature as a function of frequency with an exponent identical to one of 1D system. This exponent which universality has been verified contrasts with the BCS result. Coulomb interactions have been introduced through the study of the extended SSH-Hubbard model. The extension of this work to half-filled SSH and CM cases was also performed.

Since World War II, the Philippines has confronted threats from communist insurgents, Muslim secessionists, and a few other agitators. Recently, however, a new threat has emerged-- this time coming from a terrorist organization known as the Abu Sayyaf Group (ASG). Although the ASG is a relatively small group, it has wrought great injury to the Philippine image as of late. Common among the groups presenting a threat to internal security are that their strategies and tactics tend to be unconventional and asymmetric. This thesis seeks to determine how special operations can improve the AFP's capability to address internal security threats. The study begins by examining the security environments in which the AFP currently operates, and then proceeds to study emerging security environments in which it will likely operate. The current special operations capability of the AFP is explored and assessed, while inquiring whether it needs enhancing. Case studies of past AFP special operations against groups which posed major internal threats are analyzed to determine whether or not the doctrine and strategy of the AFP was correct, especially regarding its use of Special Operations Forces (SOF). Furthermore, this study considers the United States (U.S.) model for special operations, namely the U.S. Special Operations Forces, in proposing a special operations strategy for the AFP that is feasible, suitable, and sustainable. It is suggested that such an examination will produce a strategy that is relevant, adaptable, and responsive to dealing with the internal security environments likely to be encountered by the Philippine government.

Abstract:
Die supraleitenden Eigenschaften von komplexen Materialsystemen, wie den erst kürzlich entdeckten Eisen-Pniktiden oder den Strontium-Ruthenaten, sind oftmals durch das Zusammenspiel vieler elektronischer Orbitale bestimmt. Um die Supraleitung in derartigen Systemen besser zu verstehen, entwickeln wir in dieser Arbeit eine Multi-Orbital-Implementierung der funktionalen Renormierungsgruppe und untersuchen die Elektronenpaarung in verschiedenen charakteristischen Materialverbindungen. In den Eisen-Pniktiden finden wir hierbei mehrere Spinfluktuationskanäle, die eine Elektronenpaarung hervorrufen, sofern die Paarwellenfunktion einen Vorzeichenwechsel zwischen den verschiedenen genesteten Bereichen der Fermifläche aufweist. Abhängig von den spezifischen Materialeigenschaften, wie der Dotierung oder der Position des Pniktogenatoms, führen diese Spinfluktuationen dann zu $s_{\pm}$-wellenartiger Paarung mit durchgängiger Energielücke oder mit Knoten auf der Fermifläche. In manchen Fällen wird zudem auch $d$-wellenartige Paarung induziert, die in der Nähe des Übergangs zur $s_{\pm}$-Symmetrie einen gemischten $(s+id)$-Zustand mit gebrochener Zeitinversionssymmetrie aufweist. Diese neuartige Phase zeigt faszinierende Eigenschaften, wie zum Beispiel das spontane Entstehen von Supraströmen am Probenrand und um nichtmagnetische Störstellen. Auf Grund der durchgängigen Energielücke ist dieser $(s+id)$-Zustand energetisch begünstigt. Im Folgenden untersuchen wir zudem auch die elektronischen Instabilitäten eines weiteren außergewöhnlichen Materials -- dotiertes Graphen. Diese rein zweidimensionale Kohlenstoffverbindung ist schon seit mehreren Jahren im Fokus der Festkörperforschung und wurde mittlerweile auch durch neuartige experimentelle Verfahren dotiert, ohne die zugrundeliegende hexagonale Gittersturktur merklich zu stören. Eine theoretische Beschreibung dieses Systems erfordert die Berücksichtigung zweier nicht-equivalenter Gitterplätze, was wiederum effektiv als Zwei-Orbital-System aufgefasst werden kann. Durch die besondere Symmetrie der hexagonalen Gitterstruktur sind beide $d$-wellenartigen Paarungskanäle entartet und ahnlich der $(s+id)$-Paarung in den Pniktiden finden wir hier eine chirale $(d+id)$-Paarung in einem weiten Dotierungsbereich um van-Hove Füllung. Des Weiteren identifizieren wir Spin-Triplet-Paarung und eine exotische Form der Spindichtewelle, welche beide durch leichte Veränderung der langreichweitigen Hüpfamplituden und Wechselwirkungensparameter realisiert werden können. Als drittes Beispiel betrachten wir die Supraleitung in dem Strontium-Ruthenat Sr$_2$RuO$_4$. Die Besonderheit dieser Materialverbindung liegt in der möglichen Realisierung einer chiralen Spin-Triplet Paarung, die wiederum faszinierende Eigenschaften wie die Existenz von halbganzzahligen Flussvortizes mit nicht-Abelscher Vertauschungsstatistik aufweisen würde. Mittels eines mikroskopischen Drei-Orbital-Modells und der Berücksichtigung von Spin-Bahn-Kopplung finden wir hierbei, dass moderate ferromagnetische Spinfluktuationen immer noch ausreichen, um diesen speziellen Paarungszustand anzutreiben. Die berechnete Energielücke zeigt im Weiteren sehr starke Anisotropien auf dem $d_{xy}$-Orbital-dominierten Bereich der Fermifläche und verschwindet nahezu vollständig auf den anderen beiden Fermiflächen
The superconducting properties of complex materials like the recently discovered iron-pnictides or strontium-ruthenate are often governed by multi-orbital effects. In order to unravel the superconductivity of those materials, we develop a multi-orbital implementation of the functional renormalization group and study the pairing states of several characteristic material systems. Starting with the iron-pnictides, we find competing spin-fluctuation channels that become attractive if the superconducting gap changes sign between the nested portions of the Fermi surface. Depending on material details like doping or pnictogen height, these spin fluctuations then give rise to $s_{\pm}$-wave pairing with or without gap nodes and, in some cases, also change the symmetry to $d$-wave. Near the transition from nodal $s_{\pm}$-wave to $d$-wave pairing, we predict the occurrence of a time-reversal symmetry-broken $(s+id)$-pairing state which avoids gap nodes and is therefore energetically favored. We further study the electronic instabilities of doped graphene, another fascinating material which has recently become accessible and which can effectively be regarded as multi-orbital system. Here, the hexagonal lattice structure assures the degeneracy of two $d$-wave pairing channels, and the system then realizes a chiral $(d+id)$-pairing state in a wide doping range around van-Hove filling. In addition, we also find spin-triplet pairing as well as an exotic spin-density wave phase which both become leading if the long-ranged hopping or interaction parameters are slightly modified, for example, by choosing different substrate materials. Finally, we consider the superconducting state of strontium-ruthenate, a possible candidate for chiral spin-triplet pairing with fascinating properties like the existence of half-quantum vortices obeying non-Abelian statistics. Using a microscopic three orbital description including spin-orbit coupling, we demonstrate that ferromagnetic fluctuations are still sufficient to induce this $\bs{\hat{z}}(p_x\pm ip_y)$-pairing state. The resulting superconducting gap reveals strong anisotropies on the $d_{xy}$-dominated Fermi-surface pocket and nearly vanishes on the other remaining two pockets

Abstract:
As university programs compete to retain and increase enrollment, online courses are being created to meet the demands of a rising population of students with preferences for self-paced learning. The 2015 Babson Survey Research Group report tracking online education in the United States shows 70.7% of active degree-granting institutions open to the public have some distance-learning options. In the same report, two- and four-year public institutions offering distance learning course were reported to have “very high” rates of offerings for distance learning, with both showing over 90% of enrolled students taking at least one online course. This chapter examines the need to gap between content and application in online learning through service-learning and outlines a process for implementing service-learning projects with emphasis on e-service-learning. As distance learning continues to grow, the need for innovative pedagogical methods will also grow, which makes service-learning an attractive strategy.

Abstract:
Chapter 3 begins with an electric moment of group debate and conflict about gender, race and coalition politics at the 2019 Veterans For Peace (VFP) convention. This moment is a point of departure to analyze the often-painful clash between the older generation’s efforts to build organizational “diversity” with the younger veterans’ more expansive intersectionality. Here, the chapter zeroes in on the organizational processes in VFP and About Face that serve to limit or marginalize younger members, especially queer and women of color veterans: race and gender tokenism; assumptions—often imported from the routine masculinist values in the military—about what a proper “leader” should look like; routine microaggressions and gaslighting; and race/gender double-standards concerning expressions of emotions in social movement contexts. The chapter closes with a discussion of how tokenism, leadership assumptions, microaggressions, gaslighting, and emotional double-standards are problems being addressed across the field of social movement activism.

Abstract:
Group identity is viewed as a way to distinguish one group from another. In a competitive, ever-changing environment, group identity is considered increasingly important for a musical ensemble in terms of developing a niche, gaining audience attention, and creating a successful performing team. Thirty professional chamber musicians from “unconventional” or “non-traditional” ensembles were individually interviewed about their personal experiences working within this environment. Results show that group identity emerges in two main ways: members sharing similar characteristics, goals, and objectives, often based on repertoire choice and programming; and the sound or musical aesthetic developed through an interpretation of repertoire, instrumental combination, and the collective skills and knowledge of the musicians. This case study highlights the need for a constant vision and aesthetic concept throughout the lifetime of the ensemble in order for it to be sustainable, yet having to evolve and adapt to changing environmental factors and external influences.

Abstract:
Abstract The chapter examines the 1994 San Remo Manual in International Law applicable to Armed Conflicts at Sea, as a compilation of rules on naval warfare. It was described by the expert authors as a ‘contemporary restatement—together with some progressive development’. By 2020, another group of experts had begun discussions on revising the 1994 San Remo Manual. While a restatement may seem to make sense in view of the age of the original treaties, this chapter will question the reasons for making a restatement, and the way in which this is being done. Even if restatements may be a harmless re-reading of the law, in view of contemporary situations, a question arises with respect to how often, or how long, this can be done. The chapter explores what is labelled the ‘elasticity’ of reinterpretation, based on the understanding that reinterpretation has a purpose, and is not a merely objective act.

Abstract:
Abstract A notable example of informal lawmaking in the law of the sea context concerns piracy off the coast of Somalia. The right to combat piracy rests on a firm foundation in customary international law, reflected in the LOSC. In the early 2000s, when the international community had to face piracy as a threat to international peace and security, it became obvious that the LOSC did not meet contemporary legal requirements. States had to develop new ways of cooperating. Cooperation ensued between diverse actors within the Contact Group on Piracy off the Coast of Somalia, involving different intergovernmental organizations (IMO, UNODC) and private actors (notably the shipping industry). Efforts led to agreements including the Djibouti Code of Conduct, best management practice guidance for shipowners, and prisoner transfer agreements, to address the many practical issues being faced. The duty of cooperation in the face of piracy was, therefore, partly met through informal lawmaking.

This chapter analyses Pal Joey’s book numbers. This type of integrated song was not new to Broadway, or to the shows of Rodgers and Hart. The degree to which these songs lend sympathy to hard-to-like characters, however—characters who might otherwise be dismissed as mere cutouts of pulp-fiction villains—is remarkable. These songs helped balance O’Hara’s hard-boiled book, giving the audience the opportunity to identify with a group of character types they would otherwise be wary of associating with. The unconventional nature of many of the book songs, however, which critique, mock, and upend traditional musical comedy tropes, made way for a new critical discourse concerning musical theater.

Full text
Abstract:
New mapping, biostratigraphy, geochemistry, and organic petrology results have led to new insights into the structural evolution, depositional history, and resource potential of the Eagle Plain Basin. Apatite fission-track modelling resolves at least two distinct heating-cooling cycles and suggests that sediment was sourced from the east, as well as from the south. A recently identified marine-slope setting in the west of the basin represents a new petroleum play. Advances in understanding the age and depositional history of the Eagle Plain Group derive from new fossil localities, a new bentonite age, and detrital zircon data. Initiated in the Cenomanian, or possibly latest Albian, deposition continued until the late Maastrichtian, although post-Coniacian deposits may have been subsequently eroded, or bypassed across southern parts of the basin. New petroleum resource appraisals include new petroleum exploration-play concepts, as well as qualitative assessments of unconventional oil and gas potential.

Abstract:
In the original proposal we planned to focus on two proteins related to the actin cytoskeleton: TCH2, a touch-induced calmodulin-like protein which was found by us to interact with the IQ domain of myosin VIII, ATM1; and ERD10, a dehydrin which was found to associate with actin filaments. As reported previously, no other dehydrins were found to interact with actin filaments. In addition so far we were unsuccessful in confirming the interaction of TCH2 with myosin VIII using other methods. In addition, no other myosin light chain candidates were found in a yeast two hybrid survey. Nevertheless we have made a significant progress in our studies of the role of myosins in plant cells. Plant myosins have been implicated in various cellular activities, such as cytoplasmic streaming (1, 2), plasmodesmata function (3-5), organelle movement (6-10), cytokinesis (4, 11, 12), endocytosis (4, 5, 13-15) and targeted RNA transport (16). Plant myosins belong to two main groups of unconventional myosins: myosin XI and myosin VIII, both closely related to myosin V (17-19). The Arabidopsis myosin family contains 17 members: 13 myosin XI and four myosin VIII (19, 20). The data obtained from our research of myosins was published in two papers acknowledging BARD funding. To address whether specific myosins are involved with the motility of specific organelles, we cloned the cDNAs from neck to tail of all 17 Arabidopsis myosins. These were fused to GFP and used as dominant negative mutants that interact with their cargo but are unable to walk along actin filaments. Therefore arrested organelle movement in the presence of such a construct shows that a particular myosin is involved with the movement of that particular organelle. While no mutually exclusive connections between specific myosins and organelles were found, based on overexpression of dominant negative tail constructs, a group of six myosins (XIC, XIE, XIK, XI-I, MYA1 and MYA2) were found to be more important for the motility of Golgi bodies and mitochondria in Nicotiana benthamiana and Nicotiana tabacum (8). Further deep and thorough analysis of myosin XIK revealed a potential regulation by head and tail interaction (Avisar et al., 2011). A similar regulatory mechanism has been reported for animal myosin V and VIIa (21, 22). In was shown that myosin V in the inhibited state is in a folded conformation such that the tail domain interacts with the head domain, inhibiting its ATPase and actinbinding activities. Cargo binding, high Ca2+, and/or phosphorylation may reduce the interaction between the head and tail domains, thus restoring its activity (23). Our collaborative work focuses on the characterization of the head tail interaction of myosin XIK. For this purpose the Israeli group built yeast expression vectors encoding the myosin XIK head. In addition, GST fusions of the wild-type tail as well as a tail mutated in the amino acids that mediate head to tail interaction. These were sent to the US group who is working on the isolation of recombinant proteins and performing the in vitro assays. While stress signals involve changes in Ca2+ levels in plants cells, the cytoplasmic streaming is sensitive to Ca2+. Therefore plant myosin activity is possibly regulated by stress. This finding is directly related to the goal of the original proposal.
