description: This dissertation examines three separate data analysis studies which sought to estimate the spatial and temporal characteristics of seasonal snowpack variables in the mountainous areas of the western United States. Research began with the analysis of historical daily snow data from Snowpack Telemetry (SNOTEL) sites, located in the mountainous areas of the western United States. Three snowpack characteristics were analyzed from a climatological perspective: snow water equivalent (SWE); snow depth (SD); and snow density, all three being interrelated. Analysis of 7 years of data showed  that at a given location, during the winter season, interannual snowpack density variability was smaller than the corresponding SD and SWE changes. Hence, reliable climatological estimates of snow density could be obtained from a relatively short record period. Additionally, the spatial pattern of snowpack densi fication was qualitatively characterized using cluster analysis. The second part of research developed a regional regression-based approach to creating monthly climatological SWE grids over the western United States. The western United States was partitioned into smaller,  homogenous regions in consideration of seasonal snowpack accumulation and ablation processes. Using stepwise regression, various geographic and meteorological variables were investigated as potential predictors of change in climatological SWE within each  subregion. Results indicate that a simple regional regression approach, coupled with readily available geographic and meteorological parameters as predictors, is reliable for mapping SWE climatology from October to March. For the period of April, however, the regional equations produced increased error, especially in the North Pacifi c and Southwest regions. Lastly, performance of space-borne passive microwave SWE retrieval algorithms for the Colorado River Basin was examined by comparing daily SWE estimates from selected algorithms with SNOTEL SWE measurements for  each winter month.

Dedica dei Siracusani a Zeus Hellanios

Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2017

description:

An inscription engraved on a statue-basis offered by the Syracusan damos to Zeus Hellanios was found in unknown circumstances in Ortigia. This document remembers Gelo, son of Hiero II, as a Syracusan basileus, although he never became king because he died before his father.  Regarding the chronology of this document, the dating of the gift offered by Hiero and Gelo to the Rodian people is the most indicative: in 227 BC it seems that Gelo is mentioned alongside his father. This chronology is also confirmed by paleographic analysis. The mention of the damos in the Syracusan inscription and its personification in the well-known sculptural group donated by Gelo to the Rodians representing the Siracusan damos that crowns the Rodian people confirm the active role of the Syracusan damos during the reign of Hiero II. At this time the boule and the damos still played an important role that would be permanently lost shortly after the tyranny of Hieronymos.

description: This study aims to assess the chemical compositions of the essential oils from three Horsfieldia species namely H. fulva Warb., H. sucosa Warb. and H. superba Warb., which are found in Malaysia. The essential oils were derived from the samples through hydrodistillation which were then characterised by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Based on the findings, the H. fulva, H. sucosa and H. superba essential oils represented 98.2%, 98.7% and 98.5% of the total oils, respectively. The major component of H. fulva oil was identified to be germacrene D (20.8%), H. sucosa oil mainly contained α-cadinol (17.5%), whereas H. superba oil was rich in δ-cadinene (18.2%). To the best of our knowledge, this is the first study of the composition of the essential oils from these selected Horsfieldia species.

description: In this paper, a new class of bivariate multi-parameter Archimedean copula based on Kendall distribution using Bernstein-Bézier polynomials is introduced. The new class copula has flexible dependence properties depending on the polynomial degree and the control points. Some dependence characteristics such as Kendall’s tau, upper tail and lower tail dependence of the new Archimedean copula class are derived. The simulation procedure based on these desired dependence characteristics is presented. Also, a parameter estimation process based on minimum Cramér-von-Mises distance is also given and its estimation performance is investigated through Monte Carlo simulation study.

Year: 2022

description: This paper considers the estimation of the derivatives of a regression function based on biased data. The main feature of the study is to explore the case where the data comes from a negatively associated process. In this context, two different wavelet estimators are introduced: a linear wavelet estimator and a nonlinear wavelet estimator using the hard thresholding rule. Their theoretical performance is evaluated by determining sharp rates of convergence under Lp risk, assuming that the unknown function of interest belongs to a ball of Besov spaces Bsp,q (ℝ). The obtained results extend some existing works on biased data in the independent case to the negatively associated case.

description: The rate of development and change in information technology is accelerating. This has a great effect on nursing. In today's workplace, nurses are required to be highly skilled professionals with both information technology and nursing expertise. Health educators and administrators have encouraged the integration of informatics into the nursing curriculum. In addition, nursing informatics competencies are being recognized as an important capability of nurses. This study concerning nursing informatics competencies within the nursing profession is necessary, because it integrates the dimensions of nursing informatics competencies and suggests a useful starting point to further develop an appropriate nursing curriculum in Taiwan, resulting in better prepared nursing students to succeed in health care systems.  This study focused on identifying the nursing informatics competencies required of nurses in Taiwan. A modified Web-based Delphi method was used to implement the study seeking consensus with nursing informatics competencies from two expert groups in nursing. Nursing experts, including 23 nursing educators and 9 nursing administrators in Taiwan, were recruited. The experts responded to 323 items of the Nursing Informatics Competencies Questionnaire, modified by the researcher to include 45 additional items. Three Web-based Delphi rounds were conducted to identify nursing informatics competencies required of nurses in Taiwan. Analysis included detailed item analysis and comparison of educators' and administrators' ratings using Fisher's exact test. Competencies that met 60% or greater agreement of item importance and appropriate level of nursing practice were included. By the conclusion of Round 3, 318 nursing informatics competencies had achieved consensus of item importance and appropriate level of nursing practice. There was a high degree of agreement regarding specific nursing informatics competencies requirement for nurses in Taiwan. In addition, the study updated the list of nursing informatics competency requirements, which has international relevance since information technology is a global track in the nursing profession.

Effects of low fluence neutron bombardment on material properties of aluminum 2024 T-3 and aluminum wire
Creators: name: Reeves, Jesse Lee
Publisher: name: University of Utah
Year: 2013
Subjects: Aluminum

description: The purpose of this work was to explore the impact of neutron irradiation (1018 n/m2 to 1021 n/m2) on the aluminum alloy 2024 T-3, and several corrosion resistant treatments commonly used. The irradiation was conducted in the Utah Nuclear Engineering Programs Reactor facility using the Fast Neutron Irradiation Facility (FNIF) with a 1 MeV equivalent beam and the Center Irradiator (CI) with average neutron energy of 0.58 MeV. Historically, materials tests have focused on mechanical failures occurring at very high fluence. These same tests have generally been conducted for pure materials: the limited research existing for alloyed materials focuses on power plant materials such as zircaloy and steel. This body of information is mainly used to avoid catastrophic performance failures. Small research and test reactors operating at low power will subject core materials to fluence from 1014 n/m2 to 1024 n/m2. Aluminum alloys are very common in these systems. Materials used in research reactors, such as aluminum, have been deemed adequate due to high radiation tolerance and low mechanical failure rates. While aluminum and its alloys are a well-defined set of materials in nonradiation environments, there are very little published data for them for low fluence neutron radiation. This work measured Al 2024's (T-3) thermal conductivity, electrical resistivity, oxide layer thickness, oxide/metal interface and corrosion resistance (using passive current density) for Alodine, Anodize type II, Anodize type III and native oxide. These measurements were taken before and after irradiation and results were examined. Over the course of 30 to 50 years, property changes will likely impact thermal diffusion, corrosion properties and electrical properties. Defining these changes may give future engineers the tools needed to safely justify life extensions and build inspection methods to identify pre-failure conditions.

description: Heparan sulfate proteoglycans (HSPGs) act as signaling co-receptors by interaction of their sulfated glycosaminoglycan chains with numerous signaling molecules. In breast cancer, the function of heparan sulfate 2-O-sulfotransferase (HS2ST1), the enzyme mediating 2-O-sulfation of HS, is largely unknown. Hence, a comparative study on the functional consequences of HS2ST1 overexpression and siRNA knockdown was performed in the breast cancer cell lines MCF-7 and MDA-MB-231. HS2ST1 overexpression inhibited Matrigel invasion, while its knockdown reversed the phenotype. Likewise, cell motility and adhesion to fibronectin and laminin were affected by altered HS2ST1 expression. Phosphokinase array screening revealed a general decrease in signaling via multiple pathways. Fluorescent ligand binding studies revealed altered binding of fibroblast growth factor 2 (FGF-2) to HS2ST1-expressing cells compared with control cells. HS2ST1-overexpressing cells showed reduced MAPK signaling responses to FGF-2, and altered expression of epidermal growth factor receptor (EGFR), E-cadherin, Wnt-7a, and Tcf4. The increased viability of HS2ST1-depleted cells was reduced to control levels by pharmacological MAPK pathway inhibition. Moreover, MAPK inhibitors generated a phenocopy of the HS2ST1-dependent delay in scratch wound repair. In conclusion, HS2ST1 modulation of breast cancer cell invasiveness is a compound effect of altered E-cadherin and EGFR expression, leading to altered signaling via MAPK and additional pathways.

description: The hydrodistilled essential oils from eighteen samples of Salvia rosmarinus Spenn. collected in six localities of Elba Island (Tuscany, Italy) during three different seasonal periods were analyzed by GC-MS for the first time. Fifty-five components were identified, representing 96.8–99.6% of the total chemical composition. All the tested essential oils were characterized by a high content of monoterpenes (oxygenated 49.2–80.3%; hydrocarbons 18.7–48.3%). Among them, 1,8-cineole (26.4–49.1%), α-pinene (4.5–34.8%), camphor (1.1–18.8%) and borneol (1.7–16.2%) were the main constituents. The high amount of 1,8-cineole/α-pinene/camphor/borneol may suggest the presence of an intermediate rosemary chemotype. Statistical analysis was also performed on the essential oil (EO) composition evidenced an expected difference depending on the collection seasons, to the geographical areas and soil composition. A comparison with the essential oil composition from S. rosmarinus collected in all the other islands of Tuscan Archipelago (Italy) was also reported, together with a Multivariate Statistical Analysis.

description: Cohomological induction gives an algebraic method for constructing representations for a real reductive Lie group G from irreducible representations of reductive subgroups. Beilinson-Bernstein Localization alternatively gives a geometric method for constructing Harish-Chandra modules for G, with a fixed infinitessimal character, from some specific representations of a Cartan subgroup which depend on the character. The duality theorem of Hecht, Milicic, Schmid and Wolf establishes a relationship between modules  cohomologically induced from a Cartan and the sheaf cohomology of the D-modules on the complex flag variety for G determined by the Beilinson-Berstein construction. The main results of this thesis give a generalization of the duality theorem to partial flag varieties, which recovers cohomologically induced modules arising from larger reductive subgroups.

description:

In 193 BC, by means of a letter/πρόσταγμα – found at Nehavend, ancient Laodikeia in Media – sent to Menedemos, in charge of Media, king Antiochos III established the official cult of his wife, queen Laodike, appointing notable eponymous high priestesses, chosen among the princesses of the reign. He ordered that the letter was to be published on several stelae in the most prominent places (copies have been actually found in the region of Kermanshah, Axon nr. 171, and at Dodurga, ancient Phrygia, Ma 2002, nr. 37). In Media Laodike, daughter of Antiochus III and Laodike, and wife of her brother Antiochos (the son) coregent, was appointed. The ordinance reaches epistates Apollodotos and the city of Laodikeia in Media in three months, attesting to rapidity and effectiveness of the diplomatic exchange between the king and his officials. Active political role of queen Laodike, known from her correspondence with the cities of Sardeis, Teos, Iasos, and probably also Colophon, is enhanced by this ordinance which is the only direct proof of the existence of the dynastic Seleukid cult. The date of the establishment, implied by the text, of a high eponymous priesthood of the living king and his ancestors remains controversial.

description:

The statue base, found in Rhodes and belonging to the second/first century BC, preserves verses 454-9 of Aristophanes’ Frogs headed by the name of the author in the genitive: it is the only known epigraphic example of a classical text introduced by its author’s name. The inscribed text is also significant for the textual tradition of the Frogs, since it confirms the reading of some ancient medieval manuscripts. The inscription was found near the ancient gymnasium, where a library has recently been identified: it suggests that the text belonged to an educational context. At the same time, the religious aspect is evident both in the inscribed verses and in the comparison with a dedication from the Rhodian Peraea made by gymnasiarchs to Helios. Hence, the inscription contributes to our knowledge of the cultural, educational and religious environment of the late Hellenistic age Rhodes.

Controlled release of bioactive agents at the blood-polymer interface.

Subjects: Pharmaceuticals

description: The research described in this dissertation was conducted to characterized and evaluate a novel approach towards the improvement of blood-material interactions by reducing the effects of foreign surface-induced thrombosis of the blood.  This approach implemented the concept of controlled release of bioactive agents from a polymer matrix at the blood-polymer interface, in order to achieve maximal pharmacological effect at the desired site of activity with a minimum of general systemic effects.  The hypothesis tested were to determine if known "platelet active" agents, specifically prostaglandins E1, D2 and I1, could be physically combined as a dispersion within hydrophobic polymers (polyether urethane and plasticized polyvinyl chloride) to provide sustained release. Studies were conducted to determine if the labile chemical structure and resultant biological activity of the prostaglandins could be sufficiently stabilized within the monolithically dispersed prostaglandin-polymer systems to produce the desired pharmacological response at the blood-polymer interface.  Finally, efforts were directed towards determining if the prostaglandin-releasing polymer monolith could be effectively utilized towards the prevention of foreign surface-induced thrombus formation.  Results of the in vitro experiments indicated that prostaglandins can be dispersed within the hydrophobic polymer matrix in loading doses of sufficient amount to provide sustained release for periods of two months without significantly altering the gross physical-mechanical properties of the polymers.  Ex vivo blood studies were conducted to measure the inhibition of adenosine diphosphate induced platelet aggregation by prostaglandins released from monolithic polymers.  The results suggest that sufficient amounts of these biologically active agents were released to significantly inhibit platelet aggregation when exposed to platelet-rich plasma, even after four weeks of storage of the monoliths.  Finally, it may be interred from in vivo studies that when monolithically dispersed prostaglandin-polymer patches were implanted in the cardiovascular system of sheep, that the incidence and type of thrombus were reduced, the development of and organized endothelial structure was observed, and side effects of sever hypotension (as seen in systemic infusion of prostaglandin) were eliminated.  Overall, it may be concluded from this research that the application of controlled delivery of biologically active agents to the problem of foreign-surface-induced thrombosis can exhibit adequate platelet-sparing activity, while under proper application (i.e. site of implantation, hemodynamic conditions, and duration of use), may significantly reduce and prevent thrombus formation.

description: In continuation of our phytochemical study on the aerial part of Tanacetopsis karataviensis (Kovalevsk.) Kovalevsk, three new guaiane-type sesquiterpene lactones were isolated namely karatanolide (1), 11,13β-dihydrokaratanolide (2) and 11,13α-dihydrokaratanolide (3), in addition to the two known sesquiterpene lactones 1β,10α-dihydroxyarglabin (4) and artefin (5). The structures of the isolated sesquiterpene lactones were elucidated by IR and NMR spectroscopy. Single crystal X-ray diffraction allowed to unambiguously confirm the structure of the isolated sesquiterpene lactones. Quantum chemical calculations of the guaianolides 1–3 suggested the existence of two conformations for the seven-membered cycle. All sesquiterpene lactones from Tanacetopsis karataviensis were isolated for the first time.

description: An electrostatic microvalve for the pneumatic control of microfluidic devices is designed, modeled, fabricated, and characterized. The valve consists of several,  individually manufactured pieces assembled to form a microvalve. This creates an inexpensive microvalve that can be easily and quickly manufactured. The unique feature of this microvalve is its ability to be integrated with a microfluidic system for good portability. The valve was manufactured by depositing a thin chrome layer on a  Poly(methyl methacrylate) substrate. Thin copper foil was used as a flexible membrane that would deflect to allow air flow. When a voltage was applied between the chrome layer and the copper foil, the electrostatic force pulled the foil closed against the substrate and stopped the air flow. Parylene C was selected as a dielectric layer to provide insulation and prevent short circuiting between the chrome and copper electrodes. The valve was designed using a flexible, proximal electrode concept that decreased the required closing voltage. A mathematical model was developed to predict the voltage  required to close the valve. Tests were performed to determine the closing voltage and flowrate through the valve. The parylene dielectric thickness and the valve cavity depth were varied to find the best valve  parameters. It was determined that a valve with a 6 ?m  layer of parylene with a 58 ?m cavity depth provided the best combination of low closing voltage and high flowrate. These valves were tested to work at pressures up to 40 kPa with an average closing voltage of 680 V and an average flowrate of 1.05 mL/min. The valve showed that it also may be able to function as a flowrate control valve at higher pressures, i.e., greater than 40 kPa. It was found that dielectric charging was occurring in  the valve during operation. Switching the polarity of the control voltage with each actuation was a proposed solution that was tested and found to delay the onset of  dielectric charging. Finally, the valve was successfully used to pneumatically control flow in a simplified microfluidic device.

description: It is very unfortunate that in the 21st century, Nigeria is still lagging far behind in respect ofwomen education especially in science based disciplines. In as much as there are paucity ofdata as regards women scientists in Nigeria, it is my humble opinion that women who are inscience-based disciplines in our tertiary institutions are about 25%. The factors that appear toinfluence gender-specific differences in scientific achievements in primary, secondary andtertiary levels include: policy factors, academic factors, cultural and societal expectations fgender roles. Girls are expected in our culture to marry early as a lot of dignity is attached tomarriage. Where there is inadequate funding; only boys are trained at the expense of girls. Forthe fact that education is very poorly funded in Nigeria, coupled with high inflation, it isobserved that parents are finding it extremely difficult to cope with financing of their children’sand wards education. The girl child is always seen as the sacrificial lamb. Efforts should bedirected at providing equal access to resources in form of adequate funding of educationalsector, grants and scholarships specifically for women in science and removal of social stigmaon women who are unmarried.

description: Each year in the United States, a quarter million cases of stroke are caused directly by atherosclerotic disease of the cervical carotid artery. This represents a significant portion of health care costs that could be avoided if high-risk carotid artery lesions could be detected early on in disease progression. There is mounting evidence that Magnetic Resonance Imaging of the carotid artery can better classify subjects who would benefit from interventions. Turbo Spin Echo sequences are a class of Magnetic Resonance Imaging sequences that provide a variety of tissue contrasts. While high resolution Turbo Spin Echo images have demonstrated important details of carotid artery morphology, it is evident that pulsatile blood and wall motion related to the cardiac cycle are still significant sources of image degradation. In addition, patient motion artifacts due to the relatively long scan times of Turbo Spin Echo sequences result in an unacceptable fraction of noninterpretable studies. This dissertation presents work done to detect and correct for types of voluntary and physiological patient motion.

description: Young adults with intellectual disabilities have a higher risk of obesity compared with the general population. This analysis used a subset of data from the study, Yes We Can: An Overweight Reduction and Healthy Lifestyle Improvement Program for Young Adults with Intellectual Disabilities. Young adults with intellectual disabilities aged 18-35 completed a 12 week intervention as participants (n=11) or acted as controls (n=11). Body weight, nutrition knowledge, and attitudes toward healthy eating were assessed at pre- and postintervention for both groups. Baseline quantitative and dichotomous variables tested with chi-squared and independent samples t-tests were not significantly different. After the 3 month program, paired samples t-test and analysis of variance indicated that neither group showed significant improvements in the total scores for the nutrition knowledge and attitude surveys. However, participants in the intervention increased their social and environmental supports for nutrition (p <0.05), as compared to controls (p=.208). These results suggest that the education portion of the intervention was unable to increase nutrition knowledge or attitudes significantly, though it did help participants find new sources of support for a healthy lifestyle. In conclusion, other methods or curriculum may need to be used in this population for nutrition education.

description: Wireless communication has become an essential part of everyday life. The hunger for more data, more phone calls, more video, and more access in more places,  including vehicles, is growing massively. Communication in vehicles is particularly challenging because of their extremely high multipath environment. In addition, there is significant interest in reducing the number of wires in vehicles to reduce weight, complexity, maintenance, etc. and replace them with wireless systems. Preliminary  research shows that MIMO systems take advantage of the extreme multipath environment found in aircraft and other vehicles and also provides more consistent channel capacity than SISO systems.  The purpose of this research was to quantify complex channels (including the aircraft/vehicle environment) and their relation to other environments, evaluate MIMO in  aircraft, provide design constraints for accurately modeling complex channels, and provide information to predict optimum antenna type and location to enable  communication in aircraft/cars/buses/ships/trains/etc. and other extreme channels. The ability to evaluate and design MIMO technologies from the guidelines in this paper is potentially transformative for aircraft safety - enabling a new generation of location specific monitoring and maintenance.  Average measured capacity was found to be between 18 and 21 bits/s/Hz using a 4x4 array of antennas, and had no direct relation to the size of the channel. Site-specific capacity showed a multipath rich channel, varying between 15 to 23 bits/s/Hz. The capacity decreased for increasing measurement distance, with exceptions near reflective objects that increase multipath. Due to these special circumstances for site-specific locations within complex channels, it is recommended that 3D ray tracing be used for modeling as it is more accurate than commonly used statistical models, within 1.1 bits/s/Hz. This showed that our 3D ray tracing is adaptable to various environments and gives a more accurate depiction than statistical models that average channel variations. This comes at the cost of greater model complexity. If increased complexity is not desirable, Nakagami 1.4 could be used as the next most accurate model.  Design requirements for modeling different complex channels involve a detailed depiction of channel geometry, including height, width, length, shape (square, cylindrical, slanted walls, etc.), large windows, and reflective objects inside the channel space,  especially those near the transmitter. Overall, the multipath rich channel found in vehicles is an excellent environment for MIMO systems. These complex channels can be simulated accurately without measurement and before they are even built using our sitespecific  3D ray tracing software combined with a detailed signal model to incorporate antenna effects.

description: Many small farmers and workers on plantations in poorer countries constantly live on the poverty threshold. Those people suffer from rising commodity prices and trade structures that pass price pressure to the weakest link. Farmers are at the mercy of these structures and must comply as they have no other choice. On the consumers' side of the supply chain, it is often hard to recognize agricultural products' fairness and originality, especially in processed food. Many organizations – through food labelling - partially inform consumers about products' provenance and fairness. Whereas several studies confirm that food labels positively influence the consumers' intention to buy food, the vast number of organizations and labels are hard to evaluate and distinguish. A technology that could be a gamechanger in sustainable and fair global agriculture could be Blockchain Technology (BCT). With the help of BCT, the need for a central authority like a "fair label" agency may become obsolete, with the same or even better results. This conceptual article surveys subject matter literature and concludes that there is a noticeable research gap in the possibility of BCT replacing or enhancing fair food labels. Thus, the paper shows the potential of BCT to improve fairer agricultural supply chains and make them transparent for customers. By doing so, some research areas and research questions will be derived. Furthermore, specific directions for future research will be shown.
