description: This paper presents the results of a study of the response of a test CMOS sensor with a radiation tolerant pixel cell design to 80 keV and 100 keV electrons. The point spread function is measured to be (13.0+/- 1.7) microns at 100 keV and (12.1 +/- 1.6) microns at 80 keV, for 20 micron pixels. Results agree well with values predicted by a Geant-4 and dedicated charge collection simulation.

description: A root system $R$ of rank $n$ defines an $n$-dimensional smooth projective toric variety $X(R)$ associated with its fan of Weyl chambers. We give a simple description of the functor of $X(R)$ in terms of the root system $R$ and apply this result in the case of root systems of type $A$ to give a new proof of the fact that the toric variety $X(A_n)$ is the fine moduli space $\bar{L}_{n+1}$ of stable $(n+1)$-pointed chains of projective lines investigated by Losev and Manin.

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1983

description: This paper summarizes the efficacy and safety evaluation of ivermectin given as a single subcutaneous injection for the control of a wide range of nematode and arthropod parasites of cattle. lvermectin for the treatment and control of parasites in cattle was evaluated in 56 efficacy studies and 181 field trials prior to market introduction. A total of 8,205 cattle were involved, of which 5,094 received ivermectin at 200 mcg/ kg or more, the remainder serving as contemporary controls. It is concluded from the data that ivermectin is safe for cattle when used under practical husbandry conditions at the recommended use level. Subsequent to the compiling of the data for registration submission and prior to large scale commercial use of ivermectin injection, a total of 20,838 cattle in 18 countries were successfully involved in the research and development effort.

Multiwire proportional counters
Creators: name: Westlund, Wayne Arthur
Publisher: name: University of British Columbia
Year: 2011

description: The aim of this work is twofold: first, to develop a multilayered multiwire proportional chamber which would be useful as a position-sensitive detector in tracking the path of a beam of elementary particles and identifying the particles by their energies; and second, to measure the operating characteristics of such a chamber. A chamber has been developed which consists essentially of a stack of printed circuit board frames to which are soldered separately many parallel fine wires. A signal plane at ground potential has on either side planes at high voltage. The chamber is made gas-tight by mylar film on both ends and gas is flowed through at atmospheric pressure. The electrostatics of this type of chamber follows exactly the theory derived for the familiar proportional counter, of which the multi-wire proportional chamber is an extension. The pulse characteristics measured for the chamber agree closely with those values predicted by the theory. Such a chamber with signal wires of .0005 inch (12.7μm) spaced .10 inch (2.5 mm) apart with planes separated by ⅛ inch (3.2 mm) runs well at 1800 volts with a gas amplification factor of about 10⁴, giving a pulse 5 mv high with risetime of 25 nsec. The energy resolution shows a FWHM of 1 kev for the 5.9 kev x-ray of Fe⁵⁵, while the time resolution is at least 25 nsec. The positional sensitivity is at least as fine as the wire spacing.
Stocker Calf Receiving, Vaccination and Treatment

description: Stocker calf receiving, vaccination, and treatment is a very important part of my practice. The successful treatment of the bovine respiratory complex in stocker calves remains one of the really big challenges in bovine practice. For blackleg we vaccinate with clostridium chauvei and septicum routinely. I feel that this 2-way vaccine is enough in our practice area. I certainly have no arguement with those who are using 7-way or other multiple strain clostridial vaccines. Several of these strains really need revaccination to be really effective and in my practice most cattle would never receive the second vaccination. We use most of the antibiotic preparations that are available to us for this use.

description: The galaxy cluster Abell 523 (A523) hosts an extended diffuse synchrotron source historically classified as a radio halo. Its radio power at 1.4 GHz makes it one of the most significant outliers in the scaling relations between observables derived from multi-wavelength observations of galaxy clusters: it has a morphology that is different and offset from the thermal gas, and it has polarized emission at 1.4 GHz typically difficult to observe for this class of sources. A magnetic field fluctuating on large spatial scales (~ 1 Mpc) can explain these peculiarities but the formation mechanism for this source is not yet completely clear. To investigate its formation mechanism, we present new observations obtained with the LOw Frequency ARray at 120-168 MHz and the Jansky Very Large Array at 1-2 GHz, which allow us to study the spectral index distribution of this source. According to our data the source is observed to be more extended at 144 MHz than previously inferred at 1.4 GHz, with a total size of about 1.8 Mpc and a flux density S_144MHz = (1.52 +- 0.31) Jy. The spectral index distribution of the source is patchy with an average spectral index alpha ~ 1.2 between 144 MHz and 1.410 GHz, while an integrated spectral index alpha ~ 2.1 has been obtained between 1.410 GHz and 1.782 GHz. A previously unseen patch of steep spectrum emission is clearly detected at 144 MHz in the south of the cluster. Overall, our findings suggest that we are observing an overlapping of different structures, powered by the turbulence associated with the primary and a possible secondary merger.

On the service life modelling of Tasmanian concrete bridges
Creators: name: McGee, Rodney W.
Publisher: name: University Of Tasmania
Year: 2023

description: Various forms of concrete have been used for buildings since the time of Egyptian civilisation. The art of cement manufacture was however lost during the Middle Ages. The rediscovery of the art in the nineteenth century and the subsequent development of reinforced and prestressed concrete have seen concrete become the most commonly used construction material throughout the world. While concrete structures perform well in many situations, lack of durability in others over the last two or three decades in particular has emerged as a significant issue for asset owners internationally. While there is a number of mechanisms by which concrete deteriorates, chloride induced corrosion of bridge and marine structures and carbonation induced damage of buildings are perhaps the most significant. The various concrete deterioration mechanisms and, to a lesser extent, cover to reinforcement have been researched and reported extensively, particularly in the last twenty years. The research has however tended to focus on specific aspects of the durability performance of concrete structures. From an asset owner's perspective, it is the interaction of the various aspects of the deterioration processes that determines management strategies for affected structures and code and specification requirements for new structures. The literature relating to the interaction of the chloride and carbonation deterioration mechanisms and cover to reinforcement is however limited. The Tasmanian Department of Infrastructure, Energy and Resources is responsible for the management of a substantial bridge asset with a high proportion of its value in close proximity to salt water. The durability of its concrete structures is a significant management issue. A series of corrosion investigations and structural surveys have provided a substantial body of data which has been analysed and reported in this thesis to assist with the management of the asset and provide the basis for enhancements to specifications and codes. This work has highlighted the high variability in the parameters used to describe the durability related properties of in situ aged concrete and in cover to reinforcement. The high variability leads to high probabilities of corrosion initiation, particularly for chloride induced corrosion, that are reflected in the durability related performance of the bridge asset. A high and continuing demand for maintenance, rehabilitation and replacement of corrosion affected structures is indicated. The high variabilities also suggest that incremental changes to existing approaches to durability in aggressive environments will not achieve the improvements in performance required to increase materials related reliability to levels that are consistent with, albeit lower than, levels of structural reliability. Approaches to enhance the durability, reflecting the significant level of change required, of concrete structures are proposed.

description: A digital workflow to produce maxillofacial prostheses could improve reproducibility and aesthetic outcomes. The possibility to 3D scan patients’ limbs is given, but there is no method established to produce the prostheses from this data. In this study, tests were performed and a protocol developed to print 3D objects from water-soluble polyvinyl alcohol (PVA) in consistent quality. Prototypes of maxillofacial prosthesis were fabricated (Figure 1). Those could be used to create molds for the casting of prostheses and therefore close the gap in the digital workflow. To proof the stability of the 3D printed PVA objects, their flexural strength and flexural modulus were determined. The outcome suggests the typical anisotropic mechanical properties of 3D printed objects.

description: The rapid growth of internet users and social networking sites presents significant challenges for entrepreneurs and marketers. Understanding the evolving behavioral and psychological patterns across consumer demographics is crucial for adapting business models effectively. Particularly, the emergence of new firms targeting adolescents and future generations underscores the importance of comprehending online consumer behavior and communication dynamics. To tackle these challenges, we introduce a Machine Learning-based Digital Native Market Segmentation designed to cater specifically to the interests of digital natives. Leveraging an open-access prototype dataset from social networking sites (SNS), our study employs a variety of clustering techniques, including Kmeans, MiniBatch Kmeans, AGNES, and Fuzzy C-means, to uncover hidden interests of teenage consumers from SNS data. Through rigorous evaluation of these clustering approaches by default parameters, we identify the optimal number of clusters and group consumers with similar tastes effectively. Our findings provide actionable insights into business impact and critical patterns driving future marketing growth. In our experiment, we systematically evaluate various clustering techniques, and notably, the Kmeans cluster outperforms others, demonstrating strong segmentation ability in the digital market. Specifically, it achieves silhouette scores of 63.90% and 58.06% for 2 and 3 clusters, respectively, highlighting its effectiveness in segmenting the digital market.
Interference Alignment for Secrecy

description: This paper studies the frequency/time selective $K$-user Gaussian interference channel with secrecy constraints. Two distinct models, namely the interference channel with confidential messages and the one with an external eavesdropper, are analyzed. The key difference between the two models is the lack of channel state information (CSI) about the external eavesdropper. Using interference alignment along with secrecy pre-coding, it is shown that each user can achieve non-zero secure Degrees of Freedom (DoF) for both cases. More precisely, the proposed coding scheme achieves $\frac{K-2}{2K-2}$ secure DoF {\em with probability one} per user in the confidential messages model. For the external eavesdropper scenario, on the other hand, it is shown that each user can achieve $\frac{K-2}{2K}$ secure DoF {\em in the ergodic setting}. Remarkably, these results establish the {\em positive impact} of interference on the secrecy capacity region of wireless networks.

title: Isolation of Bacteriophage Resistant Lactic Culture Strains with Known Temperature Sensitivity
Creators: name: Jeng, Luna Ying-Chung
Publisher: name: Utah State University
Year: 1979

description: Seven strains of Streptococcus cremoris and Streptococcus lactis were tested for temperature sensitivity on a temperature gradient bar. A temperature of 37 C was the optimum for differentiating between temperature-sensitive and insensitive strains. Temperature-insensitive strains produced cell masses with absorbance values of 0.1 or higher and activity levels of 1.0 (expressed as a decrease in pH) or above at 37 C. Temperature-sensitive strains failed to produce these cell masses and activity levels, Strain selection and resistant- mutant isolation made it possible to identify ten strains of Streptococci sufficiently free of phage sensitivity for use in a cheese plant rotation program. These resistant mutants failed after being successfully used in mixed cultures for a short period of time, They became either slow acid producers or were again attacked by new bacteriophages. More work is needed to successfully isolate phage-resistant mutants suitable for cheese starters.

This detection method has been designed specifically for the acquisition of thermal and epitermal neutron images in mixed beams with a high gamma flux, and also for the study of high radioactive samples that are usually placed into research reactor pools. We also present a technique to obtain multi-spectral neutron images taking advantage of the high neutron absorption cross-section of this material in the thermal energy range, as well as around the 1.45 eV resonance. Measurements performed in a neutron beam of the RA6 nuclear research reactor located in Bariloche, Argentina, confirm the capability of the proposed technique.

Assumptions underlying French secondary education.
Creators: name: Hunt, J A
Publisher: name: University Of Tasmania
Year: 2023

description: The rapid changes which have been taking place in secondary education during the last fifteen years have led to a re-examination of the bases of post-primary education in all the major countries of the world. This has been true of France as much as of most Western nations, but the structure of secondary education in France is such that reform is not easy. Reform moves have been numerous and some part of them has been incorporated in the secondary education system. Yet the forces underlying and controlling the present organisation, though frequently questioned, have on the whole not changed greatly. This study is an attempt to discover the basic assumptions of French secondary education, to see to what extent they are at present being challenged, and to examine them in the light of the urgent needs of a nation sure to develop rapidly both technically and intellectually in this second half of the twentieth century.

description: The two most important items in receiving light weight stocker calves are time to take care of them and a place to take care of them. We have a lot of data to suggest 25% of the problems we have with receiving animals is associated with shrink involved in animal transport. Our more recent analysis of received animals suggest another 25% of our problems are associated with either the order buyer or geographical location from which the calves came. I believe we are eventually going to pin 25% of our death loss on receiving conditions. (time, facilities, and people).

Model of multilayered materials for interface stresses estimation and validation by finite element calculations

description: The mechanical problem discussed in this paper focuses on the stress state estimation in a composite laminate in the vicinity of a free edge or microcracks. To calculate these stresses, we use two models called Multiparticle Models of Multilayered Materials (M4). The first one can be considered as a stacking sequence of Reissner-Mindlin plates (5 kinematic fields per layer), while the second is a membranar superposition (2 fields per layer plus a global one). These simplified models are able to provide finite values of interfacial stresses, even on the free edges of a structure. The current paper consists of validating the M4 by a finite element analysis through describing the stress fields in both a (0,90)s laminate in tension (free-edge problem) and a transversally microcracked (0,90)s laminate. A comparison of the various energy contributions helps yield a mechanical perspective: it appears possible to define an interply energy as well as a layer energy, these energies expressing the FE 3D reality.
Pressure broadening of SiI lines in a hydrogen plasma jet
Creators: name: Beck, Reginald John
Publisher: name: University of British Columbia
Year: 2011

description: A pressurized hydrogen plasma jet is developed for pressure broadening experiments at pressures of from 4 to -20 atmospheres. Operation at low flow rates produced a plasma which was homogeneous in cross section with respect to electron density and temperature, with axial gradients, well suited for broadening experiments. The broadening of two Sil lines, X3905 Å and A2881 Å was studied. Widths and shifts due to broadening by electrons (Stark effect) and also by neutral hydrogen atoms were measured. The experimental results were compared with the theory of Griem in the case of the Stark broadening and with the Unsold theory of Van der Waals broadening for the case of the hydrogen perturbers. Comparison is also made between the experimental results and other experimental results for broadening by argon atoms. Significant disagreement was found, especially in the case of the broadening by hydrogen atoms.

description: We present the results of the search for candidate Planetary Nebulae interacting with the interstellar medium (PN-ISM) in the framework of the INT Photometric H$α$ Survey (IPHAS) and located in the right ascension range 18h-20h. The detection capability of this new Northern survey, in terms of depth and imaging resolution, has allowed us to overcome the detection problem generally associated to the low surface brightness inherent to PNe-ISM. We discuss the detection of 21 IPHAS PN-ISM candidates. Thus, different stages of interaction were observed, implying various morphologies i.e. from the unaffected to totally disrupted shapes. The majority of the sources belong to the so-called WZO2 stage which main characteristic is a brightening of the nebula's shell in the direction of motion. The new findings are encouraging as they would be a first step into the reduction of the scarcity of observational data and they would provide new insights into the physical processes occurring in the rather evolved PNe.

Leaf epicuticular waxes in the taxonomy of the Epacridaceae
Creators: name: Mihaich, Carolyn M
Publisher: name: University Of Tasmania
Year: 2023

description: Leaf epicuticular waxes have been studied in the plant family Epacridaceae from a primarily taxonomic aspect. Both the form of the wax and its chemical composition have been analysed. Wax morphology in approximately 95% of the known species from 30 of the 31 recorded genera has been examined by scanning electron microscopy (SEM). Two wax categories, amorphous and structured including four structured wax types are recognised. Distribution and variation in wax types has relevance at all levels of the taxonomic hierarchy. In a representative number of species (74) from 25 genera (covering the variation in wax types recognised from the SEM survey), complete chemical composition of the waxes has been undertaken using GC-MS. Quantitative measurements of individual components are based upon integrated peak areas. Compared with most previous reports the current study has obtained very satisfactory results from direct analysis of the crude wax, significantly reducing both preparation and analysis time for each species. The results indicate that wax structure is correlated with chemical composition and that the distribution of wax components within the family and their relative proportions between genera and species has taxonomic importance. In the final section of the thesis a taxonomic reassessment of the genus Cyathodes in Australia and New Zealand is reported incorporating data from all available sources. Chemical data, including waxes, contributes valuable additional information to the traditional morphologically based data and assists in the clarification of taxonomic problems within the genus.

(1987) on the basis of integrated photometric measurements in the Beijing-Arizona-Taiwan-Connecticut (BATC) photometric system. Here, we present multicolor photometric CCD data (in the BATC system) for the remaining 39 M31 GCs and candidates. In addition, the ages of 35 GCs are constrained by comparing our accurate photometry with updated theoretical stellar synthesis models. We use photometric measurements from GALEX in the far- and near-ultraviolet and 2MASS infrared $JHK_s$ data, in combination with optical photometry. Except for two clusters, the ages of the other sample GCs are all older than 1 Gyr. Their age distribution shows that most sample clusters are younger than 6 Gyr, with a peak at ~3 Gyr, although the `usual' complement of well-known old GCs (i.e., GCs of similar age as the majority of the Galactic GCs) is present as well.

description: We extend the definition of chordal from graphs to clutters. The resulting family generalizes both chordal graphs and matroids, and obeys many of the same algebraic and geometric properties. Specifically, the independence complex of a chordal clutter is shellable, hence sequentially Cohen-Macaulay; and the circuit ideal of a certain complement to such a clutter has a linear resolution. Minimal non-chordal clutters are also closely related to obstructions to shellability, and we give some general families of such obstructions, together with a classification by computation of all obstructions to shellability on 6 vertices.

As a novel feature, it allows sending of classical framing information via sequences of strong laser pulses that precede the quantum data. This allows synchronization, sender and receiver identification, and compensation of time-varying birefringence in the communication channel. In addition, this method also provides a platform to communicate implementation specific information such as encoding and protocol in view of future optical quantum networks. Furthermore, we report on our current effort to develop high-rate error correction.

A new parameter space is used to characterize all possible planetary orbits. Different regions in this parameter space can be associated with different characteristics of the orbits. The boundaries for these regions are clearly defined. Observational data can be directly associated with points in the regions. A possible extension of these considerations with an additional parameter for the case of Kerr geometry is briefly discussed.

description: The operating conditions of the power system have become more complex and changeable. This paper proposes a probabilistic load flow based on the cumulant method (PLF-CM) for the voltage sourced converter high voltage direct current (VSC-HVDC) hybrid system containing photovoltaic grid-connected systems. Firstly, the corresponding control mode is set for the converter, including droop control and master-slave control. The unified iterative method is used to calculate the conventional AC/DC flow. Secondly, on the basis of the probability model of load and photovoltaic output, based on the aforementioned flow results, use correlation coefficient matrix of this paper will change the relevant sample into independent sample, the cumulants of the load and photovoltaic output are obtained; then, the probability density function (PDF) and cumulative distribution function (CDF) of state variables are obtained by using Gram-Charlie series expansion method. Finally, the mean value and standard deviation of node voltage and line power are calculated on the modified IEEE 34-bus and IEEE 57-bus transmission systems. The algorithm can reflect the inherent uncertainty of new energy sources, and replace the complex convolution operation, greatly improving the calculation speed and the convergence.
Implants and Feed Additives for Feedlot Cattle

description: The introduction of diethylstilbesterol to the cattle feeding industry in the early l 950's set a milestone in terms of adding an implant or additive to the feed and improving feedlot performace. The stilbesterol (not presently approved for use) caused feedlot cattle to gain about 9 percent more rapidly and reduced feed required for gain about 7-9 percent. The industry took many years to except and understand the stilbesterol concept. In the late l 970's the first ionophore was cleared for use in feedlot cattle and in less than 60 days following final clearance by FDA for this compound, it was reported that nearly 90 percent of the cattle on feed in this country were receiving Monensin.

description: What does it really cost when an animal gets sick? A question that is extremely important to our organization. We feed over 250,000 animals a year in Southwest Kansas and the Oklahoma Panhandle. To support decision making we have a computer data management section which has helped us review and analyze the performance of selected groups of animals during the last three years.One question addressed when we started was the association of shrink to morbidity, mortality and cost of gain. Animal groups were selected for review based upon their homologous characteristics such as origin, weight, genetic background and season of the year fed.

Effects of the Environment on Neonatal Dairy Calf Health

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1983

description: The data seem to support a conclusion that infection with a variety of diarrheal and respiratory agents is an inevitable part of being a calf and that infection need not be totally prevented in order to minimize disease losses. It appears, from a functional standpoint, that in the triad of disease causality (agent, host, environment) host and environmental factors predominate. This article will examine the effects of several environmental factors on dairy calf mortality and morbidity. Diagnosis of excess dairy calf morbidity /mortality requires a detailed analysis of management practices including those related to the environment. Simply looking for infectious agents will accomplish little since the same agents can be found on low as well as high morbidity /mortality rate farms.

title: Nutrient Intakes of an Elderly Nursing Home Population
Creators: name: Hutson, Gaynell
Publisher: name: Utah State University
Year: 1979

description: A dietary nutrient intake study of ninety-five residents of a nursing home in rural community was conducted. Nutrient intakes were determined for seven consecutive days using the method of weighing food served and weighing food left by subjects. Patients on in the study. Snacks consumed between meals and vitamin and mineral supplements were included in the nutrient intakes.
Height, weight, body mass index, tricep skinfold measurement and serum blood laboratory data were obtained for each subject. Activity levels were also determined.
Results showed the mean caloric intake of the men was 2152+331. For the women the mean caloric intake was 1869+251. Nutrients less 100 percent standard (RDA 1974) were energy, calcium, thiamin, riboflavin, niacin, vitamin C, potassium, fiber and fat for the men and for the women energy, calcium, iron, thiamin, niacin, vitamin C, potassium, fiber and fat.
Mean Index of Nutritional Quality values for selected nutrients indicated that for men protein, vitamins A, C, thiamin, riboflavin, niacin, iron, calcium and phosphorus and INQ ratios of 1.0 or greater. INQ ratios for the women indicated that protein, vitamin A, C, riboflavin, niacin, iron, calcium, and phosphorus were greater than 1.0.
Correlations were found between BMI and tricep skinfold measurement and a weak correlation between kilocalories and BMI for both men and women.
All of the mean serum blood values were within normal limits except for albumin. Further studies using these methods will need to be done to determine whether high caloric intake of both men and women compared to other studies of nutrient intake of elderly subjects was possibly the result of more careful analysis or because subjects were more active.

description: We study primordial gravitational waves produced during inflation in quantum gravity at a Lifshitz point proposed by Ho${\rm\check{r}}$ava. Assuming power-counting renormalizability, foliation preserving diffeomorphism invariance, and the condition of detailed balance, we show that primordial gravitational waves are circularly polarized due to parity violation. The chirality of primordial gravitational waves is a quite robust prediction of quantum gravity at a Lifshitz point which can be tested through observations of cosmic microwave background radiation and stochastic gravitational waves.

description: A detailed study of total, Coulomb and nuclear breakup cross sections dependence on the projectile ground-state binding energy $\varepsilon_b$ is presented, by considering the $^8$Li+$^{12}$C and $^8$Li+$^{208}$Pb breakup reactions. To this end, apart from the experimental one-neutron separation energy of $^8$Li nucleus ($\varepsilon_b=2.03$~MeV), lower values of $\varepsilon_b$ down to $\varepsilon_b=0.01$~MeV, are also being considered. It is shown that all breakup processes become peripheral as $\varepsilon_b\to 0.01$ MeV, which is understood as due to the well-known large spacial extension of ground-state wave functions associated to weakly-bound projectiles. The Coulomb breakup cross section is found to be more strongly dependent on $\varepsilon_b$ than the nuclear breakup cross section, such that the Coulomb breakup becomes more significant as $\varepsilon_b$ decreases, even in a naturally nuclear-dominated reaction. This is mainly due to the long-range nature of the Coulomb forces, leading to a direct dependence of the Coulomb breakup on the electromagnetic transition matrix. It is also highlighted the fact that the nuclear absorption plays a minor role for small binding when the breakup becomes more peripheral.

The Role of Colostrum in Managing Calf Health

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1983

description: Passive immunity acquired by the newborn calf following ingestion of colostrum is a major determinant, but not the sole determinant, of health during the neonatal period. Colostral immunoglobulins provide both circulating antibody and antibody active at local surfaces such as the gut. There is a high prevalence of failure of passive transfer of colostral immunoglobulins in calves. The transfer of colostral immunoglobulins to the calf is influenced by factors such as age at first feeding, method of feeding, the volume of colostrum ingested and its immunoglobulin concentration, the feeding of single versus pooled colostrum, a possible effect from the presence of the dam, seasonal influences and individual calf variation in efficiency of absorption. In this paper the influence of each of these individual factors will be discussed, however, in most herds the occurence of failure of passive transfer results from an interplay between most of these influences.

Subjects: subject: Numerical Analysis (math.NA)

description: The fast multipole method (FMM) has had great success in reducing the computational complexity of solving the boundary integral form of the Helmholtz equation. We present a formulation of the Helmholtz FMM that uses Fourier basis functions rather than spherical harmonics. By modifying the transfer function in the precomputation stage of the FMM, time-critical stages of the algorithm are accelerated by causing the interpolation operators to become straightforward applications of fast Fourier transforms, retaining the diagonality of the transfer function, and providing a simplified error analysis. Using Fourier analysis, constructive algorithms are derived to a priori determine an integration quadrature for a given error tolerance. Sharp error bounds are derived and verified numerically. Various optimizations are considered to reduce the number of quadrature points and reduce the cost of computing the transfer function.

Publisher: name: University of British Columbia
Year: 2011

description: An infrared Fourier spectrophotometer has "been set up in the solid state laboratory of the University of British Columbia. A cryostat has been built and adapted to the spectrometer. A computer program to analyze the data and plot the spectrum has been written. As a demonstration of the system's capability, the transmission spectrum from 40 cmˉ¹ to 330 cmˉ¹ of boron doped silicon was obtained for the sample at liquid helium temperature. This spectrum was compared to earlier work done by Colbow in the region 240 cmˉ¹ to 330 cmˉ¹. A spectrum of boron and indium doped silicon was Investigated in the hope of finding Bˉ and In⁺ ionized centres. These were not found at the impurity concentrations and temperatures used. A transmission spectrum of intrinsic silicon at liquid helium temperature was obtained for the region 40 cmˉ¹ to 330 cmˉ¹ A comparison of the above spectra suggests that the low energy tail of the boron doped and boron and indium doped samples is due to a frequency dependent value of reflectivity as Is seen from the spectrum for intrinsic silicon.
title: The Incidence of Lactose Malabsorption Among Cache Valley Young Adults
Creators: name: Cowles, Eileen Donna
Publisher: name: Utah State University
Year: 1979

description: Twenty-four young adults, ages 18 to 30, from Cache Valley were studied to determine the incidence of lactose malabsorption. Lactose malabsorption was determined by a two-hour oral lactose tolerance test. The criteria for a malabsorber was a flat glucose curve in which there was a rise in serum glucose less than 20 mg. per 100 ml. above the fasting level. Four of the subjects were found to be lactose malabsorbers. The incidence of lactose malabsorption was determined to be 16.67 per cent. A 95 per cent confidence interval for this study indicated that the actual percentage could be expected to be between 1.76 and 31.58 per cent with 75 per cent confidence. Two of the subjects determined to be lactose malabsorbers developed gastrointestinal symptoms associated with lactose intolerance: abdominal cramping, flatulence and/or diarrhea. The daily milk intake varied greatly among both lactose absorbers and malabsorbers subjects.
