description: In the southern coastal region of California the Tertiary
formations are extensively developed and present many problems of geological interest. The development of their petroleum contents make them of marked economic interest. An
area in the Santa Ynez Range was chosen with a view to working out in some detail the structure and stratigraphy of this division of the coast range.

The earliest reports of the geology of the Santa Ynez Range are to be found in the Pacific Railroad Exploration Reports and the Geological Survey of California. Thomas Antisell and Albert H. Campbell described the main topographic features, and noted the presence of asphaltic rocks. The Tertiary age of most of the sedimentary rocks was recognized, but the structural features and the relations of the rocks were in the main misinterpreted. Fairbanks in his paper on the "Geology of Northern Ventura, Santa Barbara, San Luis Obispo, Monterey, and San Benito Counties" discussed the Santa Ynez Range. "There can be no doubt that the main portion of the Santa Ynez Range is Miocene with a general anticlinal structure, well shown in San Marcos Pass". "The normal type of anticlinal structure is also marked by an east west compression, producing features, however, of secondary importance."
"As viewed from the south at various points the range consists of heavy bedded sandstones dipping at a high angle to the south." J.D. Whitney, Blake, Diller, and Eldridge, have made reports on the general region of the Santa Ynez Valley. Arnold and Anderson have covered this area in their report on the Santa Maria Oil District of California.

description: Structural phase transition studies employing low-temperature transmission electron microscopy, and low-temperature x-ray diffraction have been carried out on nearly stoichiometric (δ=0.01) and off-stoichiometric (δ=0.12) versions of La0.2Sr0.8MnO3-δ manganite. The nearly stoichiometric La0.2Sr0.8MnO3-δ under goes a cubic to Jahn-Teller distorted C-type antiferromagnetic tetragonal phase-transition at 260K. For off-stoichiometric La0.2Sr0.8MnO3-δ the Jahn-Teller distorted tetragonal phase transition gets totally suppressed and the basic perovskite lattice remains cubic but shows a charge ordered phase. Stabilization of charge ordered phase in the absence of cooperative Jahn-Teller distortion has been attributed to coulomb-repulsion and Hunds coupling energy. The off-stoichiometric sample shows characteristically different physical properties. This has been realized through transport, magnetic and calorimetric measurements. A smooth crossover from variable range hopping transport to power-law dependence of resistivity (ρ) on temperature (T) i.e. ρ=C.T-α has been realized. This has been attributed to multistep inelastic tunneling through channels involving localized states around oxygen vacancy sites.

description: We report discovery of a dwarf galaxy in the Leo Triplet. Analysis of the neutral hydrogen distribution shows that it rotates independently of the tidal tail of NGC 3628, with a radial velocity gradient of 35-40 km s$^{-1}$ over approximately 13 kpc. The galaxy has a very high neutral gas content, explaining large part of its total dynamic mass - suggesting small dark matter content. As it is located at the tip of the gaseous tail, this strongly suggests its tidal origin. Should it be the case, it would be one of the most confident and closest (to the Milky Way) detections of a tidal dwarf galaxy and, at the same time, a most detached from its parent galaxy ($\approx$140 kpc) object of this type.

description: A regioselective addition of alkynylsilanes across unactivated, terminal alkenes is reported. The reaction is initiated by the capture of a sterically unhindered silylium ion by a silylated phenylacetylene derivative to form a bis(silylated) ketene‐like carbocation. This in situ‐generated key intermediate is the actual catalyst that maintains the catalytic cycle by a series of electrophilic addition reactions of silylium ions and β‐silicon‐stabilized carbocations. The computed reaction mechanism is fully consistent with the experimental findings. This unprecedented two‐component carbosilylation establishes a C(sp3)−C(sp) bond and a C(sp3)−Si bond in atom‐economic fashion.

description: We present narrow-band photometric measurements of the exoplanet GJ 1214b using the 10.4 m Gran Telescopio Canarias (GTC) and the OSIRIS instrument. Using tuneable filters we observed a total of five transits, three of which were observed at two wavelengths nearly simultaneously, producing a total of eight individual light curves, six of these probed the possible existence of a methane absorption feature in the 8770 - 8850 Å region at high resolution. We detect no increase in the planet-to-star radius ratio across the methane feature with a change in radius ratio of $Δ$R = -0.0007 $\pm$ 0.0017 corresponding to a scale height (H) change of -0.5 $\pm$ 1.2 H across the methane feature, assuming a hydrogen dominated atmosphere. We find a variety of water and cloudy atmospheric models fit the data well, but find that cloud-free models provide poor fits. These observations support a flat transmission spectrum resulting from the presence of a high-altitude haze or a water-rich atmosphere, in agreement with previous studies. In this study the observations are predominantly limited by the photometric quality and the limited number of data points (resulting from a long observing cadence), which make the determination of the systematic noise challenging. With tuneable filters capable of high resolution measurements (R ~ 600 - 750) of narrow absorption features, the interpretation of our results are also limited by the absence of high resolution methane models below 1 $μ$m.

description: The quantum thermodynamic property of the fractional damping system is investigated extensively. A fractional power-law decaying entropy function is revealed which presents another evidence for the validity of the third law of thermodynamics in the quantum dissipative region. Several non-trivial characters are excavated such as that the entropy varies from a non-linear diverging function to a semi-linear decaying function of the fractional exponent as the temperature tends to absolute zero.

description: The impact of the solvent composition on wax oleogels is addressed by (1) increasing polar components (PC) in sunflower and canola oil through thermal treatment and (2) removing minor components from untreated oils by column chromatography. Subsequently, oleogels are produced at 0.05 and 10 °C min−1 using 4% or 10% w/w of either sunflower, rice bran, candelilla, or beeswax. Oleogels firmness, break‐up behavior during amplitude sweeps, and gelation and dissolution are studied using penetration tests, rheology, and differential scanning calorimetry (DSC), respectively. Moreover, the crystal morphology of 4% w/w samples, gelled at 10 and 0.05 °C min−1, is studied using bright field microscopy. Distinct effects caused by the presence or absence of PCs on the characteristics mentioned above are observed, depending on the wax type. The formation of highly ordered wax crystal structures is favored in oils without PCs and low cooling rates. Data on gel formation and dissolution reveal a decrease in wax solubility in the absence of PCs. In contrast, the critical gelation concentration (CGC) decreases when PCs are present, independent of their concentration, indicating that PCs aid network formation. Moreover, the break‐up behavior during oscillatory stress is significantly different, leading to more network fragments and higher energy dissipation with increasing strain. Practical applications: It is found that the oil composition, in particular, the fatty acid composition of TAGs and dissolved minor polar oil components, profoundly affect wax oleogel properties. Although not all mechanisms leading to these changes can be unraveled within this study, a fundamental understanding of solvent composition's role on oleogel formation, dissolution, and network properties is vital in the light of product applications. Moreover, trustworthy and comparable oleogel research can only be achieved if the impact of solvent composition is considered in experiments. That way, the capability of oleogels for industrial applications might be maximized. For that, a detailed characterization of oil quality, particularly the fatty acid composition and presence of minor polar components, is required to conduct reliable scientific work in oleogel research.

description: Abstract:
This project was designed to determine the effects of nitrogen fertilization on the quality and quantity of streamflow eminating from an eastern hardwood forest watershed. A 40.67 ha watershed, located in mountainous eastern Kentucky, was aerially fertilized in late April 1975. The forest stand was principally oak, hickory, and yellow poplar, 50 - 55 years of age and in a relatively undisturbed condition. A helicopter applied anunonium nitrate at a rate of 504 kg/ha. Because a large part of applied nitrogen fertilizer ends up in the highly mobile nitrate nitrogen.form, this is the principal ion monitored in this study. No effort was made to avoid live streams during application and, consequently, very high levels of nitrate nitrogen were detected (640 mg/1) in streamfiow within the watershed. Levels potentially toxic to humans and animals persisted in the streamflow for several days following application. Although elevated concentrations of nitrate nitrogen persisted in streamflow leaving the watershed over a two year period no algal blooms or excessive growth of aquatic plants were noted. Rather high concentrations of nitrate nitrogen were found in the soils of the watershed, with greatest concentrations in the surface layer (0 - 5 cm), intermediate amounts at 15 - 20 cm, and the lowest concentrations at the 41 - 46 cm depth. The effects of the fertilizer application on soils persisted less than one year in the 0 - 46 cm depth sampled. Analysis of streamf1ow records indicated a reduction in water yield the first and second growing seasons after treatment. Gross budgeting of nitrate nitrogen inputs vs. outputs suggests this anion accumulates on these relatively undisturbed watersheds at an annual rate of 3 to 5 kg/ha.

description: Current research on wax-based oleogels indicates wax esters to be the key component in many natural waxes. This necessitates understanding the properties of pure wax esters to unravel the gelling mechanism in wax-based oleogels. Therefore, available literature data on pure wax esters is summarized and critically reviewed. The detailed analysis of the pre-existing data on crystallographic (SAXS) and thermal properties, facilitates the interpretation of subsequently performed experiments: Specific wax esters with different carbon numbers and symmetries were studied as such and in oleogels formed in combination with medium chained triglyceride oil at inclusion levels of 10% (w/w). They were characterized regarding their thermal (differential scanning calorimetry [DSC]) and viscoelastic (oscillatory rheology) behavior. It is found that all observations concerning pure wax esters behave systematically, linking molecular makeup, crystal structure, and behavior. The experimental study of oleogels structured by four different binary mixtures of wax esters revealed that substantial chain length differences induce separate crystallization (CN30 + 36 and CN30 + 42). Mixtures of wax esters with only limited chain length difference (≤ 2 carbon atoms) reconfirmed earlier speculations on mixing behavior and crystal structure. Applying mixtures of wax esters only differing in their position of the ester bond (CN36 [14_22] + CN36 [22_14]) indicated ideal mixing behavior in the solid phase of the gels. Surprisingly, the data revealed that additional thermal events occur at specific mixing ratios, predominantly at 1:1 (w/w). Their supposed relation to compound formation certainly needs further confirmation. Rheological analysis confirmed that sequential crystallization results in highest firmness values for the systems studied.

description: Herein, the design and synthesis of a highly photoluminescent and electrically conductive metal–organic framework [Zn{Cu‐p‐H6TPPA}]⋅2 [(CH3)2NH] (designated as GTUB3), which is constructed using the 5,10,15,20‐tetrakis [p‐phenylphosphonic acid] porphyrin (p‐H8TPPA) organic linker, is reported. The bandgap of GTUB3 is measured to be 1.45 and 1.48 eV using diffuse reflectance spectroscopy and photoluminescence (PL) spectroscopy, respectively. The PL decay measurement yields a charge carrier lifetime of 40.6 ns. Impedance and DC measurements yield average electrical conductivities of 0.03 and 4 S m−1, respectively, making GTUB3 a rare example of an electrically conductive 3D metal–organic framework. Thermogravimetric analysis reveals that the organic components of GTUB3 are stable up to 400 °C. Finally, its specific surface area and pore volume are calculated to be 622 m2 g−1 and 0.43 cm3 g−1, respectively, using grand canonical Monte Carlo. Owing to its porosity and high electrical conductivity, GTUB3 may be used as a low‐cost electrode material in next generation of supercapacitors, while its low bandgap and high photoluminescence make it a promising material for optoelectronic applications.

description: We present MBIS (Multivariate Bayesian Image Segmentation tool), a clustering tool based on the mixture of multivariate normal distributions model. MBIS supports multi-channel bias field correction based on a B-spline model. A second methodological novelty is the inclusion of graph-cuts optimization for the stationary anisotropic hidden Markov random field model. Along with MBIS, we release an evaluation framework that contains three different experiments on multi-site data. We first validate the accuracy of segmentation and the estimated bias field for each channel. MBIS outperforms a widely used segmentation tool in a cross-comparison evaluation. The second experiment demonstrates the robustness of results on atlas-free segmentation of two image sets from scan-rescan protocols on 21 healthy subjects. Multivariate segmentation is more replicable than the monospectral counterpart on T1-weighted images. Finally, we provide a third experiment to illustrate how MBIS can be used in a large-scale study of tissue volume change with increasing age in 584 healthy subjects. This last result is meaningful as multivariate segmentation performs robustly without the need for prior knowledge

description: In the Ravenna quadrangle, north central Los Angeles county, approximately 8,400 feet of middle Miocene (?) fanglomerates and 3,600 feet of curiously interbedded basalts are exposed.  They lie unconformably on a pre-Tertiary basement and unconformably under the Mint Canyon formation (upper Miocene).  For this group of rocks the name "Vasquez Series" is suggested to replace the term "Escondido Series" of O.H. Hershey, which is preoccupied.

The fanglomerates of the Vasquez Series are composed of angular fragments of anorthosite, quartz diorite, granite, and gneiss, commonly a foot or two in diameter though larger fragments are abundant.  The fragments are embedded in a sparse matrix of sand and gravel cemented by calcite and iron oxides.  The rude and irregular strata of the series are typically red, brown, or white in color.  These sediments accumulated rapidly under semi-arid conditions in a large canoe-shaped basin and formed a series of coalescing alluvial fans which sloped in general toward the west.  The upper part of the series contains local occurrences of fine silty beds of lacustrine origin.

Some of the interbedded basalts exhibit phenomena suggestive of intrusive emplacement, others are clearly extrusive.  These lavas range from massive hypohysline porphyricitc rocks to spongy amygdaloidal masses.

Subsequent to deposition, the Vasquez Series was uplifted and deformed.  After an epoch of erosion the basaltic conglomerate of the basal Mint Canyon (middle Miocene (?) was laid down.

Faulting is greatly predominant over folding in the Ravenna quadrangle.  Since upper Miocene time two periods of faulting have occurred.  The first characterized by the Soledad fault, a normal fault, and the second characterized by a series of northeast trending strike slip faults.  This last group of faults is clearly due to shearing stresses.

Physiographically the area has a mature topography which was formed by the end of the Pleistocene.  This mature topography is now being dissected by headward working streams rejuvenated in recent time.

description: Iron-based catalysts are employed in CO2-FTS due to their ability to convert CO2 into CO in a first step and their selectivity towards higher hydrocarbons in a second CO hydrogenation step. According to the literature, iron carbides represent the active phase for hydrocarbon formation and are claimed to emerge in the presence of CO. We propose nanostructured FeOx films as model systems to assess information about the complex phase transformations during CO2-FTS. Mesoporous hematite, ferrihydrite, maghemite, maghemite/magnetite films were exposed to CO2-FTS atmospheres at 20 bar and 300 °C. Up to three distinct phases were observed depending on the time-on-stream (TOS): a sintered maghemite/magnetite phase, a carbidic core-shell structure, and a low-crystalline, needle-type oxide phase. Our findings indicate that the formation of an intermediary maghemite/magnetite phase, predominant after short TOS (30 h), precedes the evolution of the carbide phase. Yet, even after prolonged TOS (185 h), no full conversion into a bulk carbide is observed.

Dagens velferdstjenester søker nye og innovative løsninger på en rekke områder, der etablerte tiltak ikke strekker til, og dyreassisterte innovasjoner kan representere slike nye muligheter. I artikkelen blir det vist til forskning om to konkrete tiltak der barn og unge er involvert i samhandling med dyr: Inn på tunet og prosjekt Lesehund. Her drøftes noen sentrale dimensjoner ved slike tiltak i lys av begrepet livsmestring: 1) sosialt felleskap, relasjoner og støtte; 2) energi, pågangsmot og mestring og 3) deltakelse i arbeid og i fellesskap i samfunnet.

description: We use multi-scale techniques to determine the extent of local inhomogeneity and superconductivity in Ca$_{0.86}$Pr$_{0.14}$Fe$_{2}$As$_{2}$ single crystal. The inhomogeneity is manifested as a spatial variation of praseodymium concentration, local density of states, and superconducting order parameter. We show that the high-$T_{c}$ superconductivity emerges from clover-like defects associated with Pr dopants. The highest $T_{c}$ is observed in both the tetragonal and collapsed tetragonal phases, and its filamentary nature is a consequence of non-uniform Pr distribution that develops localized, isolated superconducting regions within the crystals.

description: We present a comparative study of our valence band photoemission results on Nb2Pd1.2Se5 and Nb2Pd0.95S5 superconductors which is supported by our DFT based electronic structure calculations. We observe that the VB spectra of both the compounds are qualitatively similar, except slight difference in the binding energy position of all features between the two compounds which could be the result of different electronegativity of Se and S atom. The calculated density of states reveal that the VB features are mainly composed of Pd Se S hybridized states. The nature of DOS originating from the distinctly coordinated Pd atoms is different. Further, the involvement of the various Pd 4d and Nb 4d states in crossing of Fermi level signifies the multiband character of these compounds. In addition, we find a temperature dependent pseudogap in Nb2Pd0.95S5 which is absent in Nb2Pd1.2Se5.

description: Timms Point is located in the southeastern part of the town of San Pedro, Los Angeles County, California, just east of the south end of Harbor Boulevard, along the bluff facing the harbor. It is part of the abandoned sea cliff extending from a locality near Point Fermin northward along the east side of the town. The cliff is about forty feet high and its top represents the lowest of a number of marine terraces cut in the Palos Verdes Hills.

Since Arnold studied the stratigraphy and faunas of San Pedro no account of the section exposed at Timms Point has been published. As at that time the exposures there were poor, only 28 species of mollusks were collected and no detailed observations could be made with reference to the stratigraphy. It, therefore, seems desirable to record the results of an examination of the stratigraphy and fossils.

A fauna of 155 species of mollusks, bryozoa, and brachiopods has now been collected and studied from the so-called Pliocene beds exposed at Timms Point. Foraminifera and ostracods, the former in great abundance, were collected, but not studied. A close scrutiny of the physical evidence and the fossils seems to indicate the presence of two minor faunal zones.

description: We determine the fraction of events with double parton (DP) scattering in a single ppbar collision at sqrt{s}=1.96 TeV in samples of photon + 3 jet and photon + b/c jet + 2 jet events collected with the D0 detector and corresponding to an integrated luminosity of about 8.7 fb^{-1}. The DP fractions and effective cross sections (sigma_eff) are measured for both event samples using the same kinematic selections. The measured DP fractions range from 0.21 to 0.17, with effective cross sections in the photon + 3 jet and photon + b/c jet + 2 jet samples of sigma_eff^incl = 12.7 +- 0.2 (stat) +- 1.3 (syst) mb and sigma_eff^HF = 14.6 +- 0.6 (stat) +- 3.2 (syst) mb, respectively.

title: The use of ritualised acts in late medieval mystical narratives
Creators: name: Buncombe, Miriam
Publisher: name: University of St Andrews
Year: 2015

description: This thesis addresses the function of the depiction of ritualised acts in late medieval mystical narratives through the use of four case studies, those of Mechthild of Magdeburg’s Flowing Light of the Godhead (c. 1260), Angela of Foligno’s Memorial (c. 1270), the Vita et Revelationes of Agnes Blannbekin (c. 1315), and the Adelhausen sister-book (1318). The rituals of the Church appear throughout these texts, for instance in the celebration of saints’ feasts and daily masses, to which these women devoted much of their time. Sacramental and liturgical practice portrayed within these accounts has been incorporated into the spiritual and mystical lives of women in various imaginative ways. Yet participation within such rites was not only a common and pious act, but also reinforced a social and religious hierarchy and offered access to the real presence of God. This discussion proposes that mystical texts are carefully constructed narratives which employ ritual acts as a strategy to frame and authorise their subjects. Positioning the mystic and their voice within, or interwoven with, both the performed rite, such as communion, or references to these rituals, for instance in the use of sacred spaces like the altar or objects such as the chalice, such texts can use such ritualised elements to embed the unusual or unstable mystical element in the familiar and orthodox. These ritual structures, which were theologically complex, are also integrated in order to explain and express aspects of the mystic’s task and message. Through close study of the placement of ritual, the way in which it is described, and how it is changed or appropriated within the narrative’s depiction, this thesis seeks to understand the ways in which rituals and references to rituals are deliberately considered and purposefully included within these spiritual texts.

description: Abstract: Until the second half of the 1960s, children’s relations caught little attention among adults and science as such. This changed dramatically when the concept of “mobbing” was introduced around 1970. Today, “mobbing” or bullying, is an acknowledged problem in schools all over the world, and has spurred prevention programs and a successful field of research. Through studies of historical sources, such as research literature, newspapers and political documents from the early 1970s and onward, this article shows how bullying research developed in the intersection between science and politics. Norwegian research on bullying developed into a specific way of knowing known as technoscience, characterised by research on bullying, development of prevention programs and evaluation studies on the effects of these programs. A specific feature of this development is a reciprocal influence that both researchers and politicians benefitted from.

description: 	Animal communication systems are complex, but in many species relatively little is known about how they develop. Insight into the development of adult repertoires, considering how factors such as genetics, environment and learning contribute to signal changes, provides a more comprehensive understanding of communication. This thesis documented vocal learning and development in the grey seal. In chapter 3, vocal repertoires of grey seal pups were recorded from birth through their first year, and were compared to calls of other seals across life stages, from pups to adults. By examining call parameters that were similar in animals of the same age, size, and sex, changes that may be attributed to physical development and morphology were identified. Past studies have indicated that seals may also have advanced vocal learning abilities, however the extent of these capabilities was unknown. In this thesis, vocal learning in juvenile grey seals was tested considering both how the seals learn to produce calls as well as gain information from perceived sounds. In chapter 4, grey seals were shown to be capable of vocal usage learning by producing specific calls in specific contexts. In chapter 5, grey seals displayed control over the structure of their calls as they could imitate novel sound models, demonstrating vocal production learning. Lastly, in chapter 6 grey seals gained information from perceived sound signals and used them to their benefit to locate food, demonstrating acoustic comprehension learning. Adult grey seals have complex call repertoires, and in this thesis I have shown how their calls develop with physiological growth and experience, as well as how they can gain information from perceived sound signals.

description: Over the past decade it has become apparent that a class of `bursting pulsars' exist with the discovery of PSR J1752+2359 and PSR J1938+2213. In these pulsars, a sharp increase in the emission is observed that then tends to systematically drop-off from pulse-to-pulse. In this paper we describe the discovery of such a relationship in high-sensitivity observations of the young (characteristic age of 90,000 yrs) 0.33 s pulsar B0611+22 at both 327 MHz and 1400 MHz with the Arecibo radio telescope. While Nowakowski previously showed that B0611+22 has mode-switching properties, the data presented here show, for the first time, that this pulsar emits bursts with characteristic time-scales of several hundred seconds. At 327 MHz, the pulsar shows steady behaviour in one emission mode which is enhanced by bursting emission slightly offset in pulse phase from this steady emission. Contrastingly at 1400 MHz, the two modes appear to behave in a competing operation while still offset in phase. Using a fluctuation spectrum analysis, we also investigate each mode independently for sub-pulse drifting. Neither emission mode (i.e. during bursts or persistent emission) shows the presence of the drifting sub-pulse phenomenon. The bursting phenomena seen here appears to be a hybrid between bursting seen in other pulsars and the bistable profile illumination behaviour reported in two other pulsars by Rankin et al. Further examples of this cross-frequency behaviour are required, as this phenomenon may be quite common among the pulsar population.
