description: This study compared consumption patterns of WIC children with those of three different comparison groups: eligible nonparticipating children living in non-WIC households, eligible nonparticipating children living in WIC households, and children living in households whose income is too high to be eligible for WIC. The study provides strong evidence that participation in the WIC program increases consumption of at least some types of WIC-approved foods.

description: Solid solutions of nominal composition [ZnGa$_2$O$_4$]$_{1-x}$[Fe$_3$O$_4$]$_x$, of the semiconducting spinel ZnGa$_2$O$_4$ with the ferrimagnetic spinel Fe$_3$O$_4$ have been prepared with $x$ = 0.05, 0.10, and 0.15. All samples show evidence for long-range magnetic ordering with ferromagnetic hysteresis at low temperatures. Magnetization as a function of field for the $x$ = 0.15 sample is S-shaped at temperatures as high as 200 K. Mössbauer spectroscopy on the $x$ = 0.15 sample confirms the presence of Fe$^{3+}$, and spontaneous magnetization at 4.2 K. The magnetic behavior is obtained without greatly affecting the semiconducting properties of the host; diffuse reflectance optical spectroscopy indicates that Fe substitution up to $x$ = 0.15 does not affect the position of the band edge absorption. These promising results motivate the possibility of dilute ferrimagnetic semiconductors which do not require carrier mediation of the magnetic moment.

description: Angesichts der Schwierigkeit, känozoisch aktive Störungen oder Flexuren in gehobenen Gebieten mit nur lückenhaft erhaltenen känozoischen Deckschichten (z. B. als Terrassen) nachzuweisen, wurde versucht, fotogeologische Methoden als Hilfsmittel einzusetzen. Von Landsat-I- und II-Aufnahmen wurde das Bruchmuster der betreffenden Region auskartiert. Das Fotolineationenmuster wurde in zwei Arbeitsschritten eingesetzt: 1. Lineationen wurden in die Feldkarten übertragen, um die Geländearbeiten auf die unmittelbare Umgebung der Lineationen zu konzentrieren, wo Höhenunterschiede an der Oberfläche und an der Basis känozoischer Ablagerungen untersucht wurden. 2. Anhand der fotogeologisch erkannten Bruchstrukturen wurden Großschollen mit typischem Richtungsverteilungsmuster gegeneinander abgegrenzt. Sodann wurde untersucht, ob Terrassenlängsprofile an den Großschollengrenzen signifikante Gefällsbrüche aufweisen. An einigen Beispielen aus den Talregionen von Mosel, Saar, Prims und Nahe wird gezeigt, daß die Methode erfolgversprechend angewendet werden kann: in einigen Fällen bilden Lineationen in Terrassenkörpern mit hoher Wahrscheinlichkeit junge Störungen von zweitrangiger Bedeutung ab. Zonen mit stärker gehobenen Terrassen oder Tertiärsedimenten zeichnen sich durch ein charakteristisches Muster von Lineationen ab und werden von langgestreckten Lineamenten begrenzt, die möglicherweise jungen Flexuren folgen.

title: An investigation of mothers attributions and affective and behavioural responses to pre-school childrens problem behaviour: a group comparative study
Creators: name: Lorenc, Diana
Publisher: name: The Open University
Year: 1997

description: An independent groups comparative design was used to investigate mothers' attributions and affective-behavioural responses in relation to their pre-school child's problem behaviour. Mothers' beliefs about the age at which children develop aspects of social understanding and skills was also investigated. One group involved mothers whose pre-school child was identified as presenting with a behaviour problem, a second group involved' mothers of a 'non-problem' pre-school child. A premise of the research, however, was that all young children will at times present their parents with behaviour management problems. Participants were recruited from a number of sources, predominantly within community settings. Twenty-one participants were assigned to each group. The main findings were that groups differed significantly in terms of the extent to which participants believed their child had misbehaved in order to deliberately upset them, with problem group participants rating their child as having acted more intentionally. There was some evidence that groups also differed in relation to the extent to which they believed their cnild had control over the causes of their misbehaviour, with non-problem group participants rating their child as having more control. No group differences were found in terms of mothers' estimates of the age at which children develop a range of skills and understanding. Groups were also found to differ significantly in the number of child misbehaviour incidents they resolved and the type of behaviour response strategies used. Participants in the non-problem group were more likely to use 'co-operative' responses than those in the problem group. There was also a suggestion of some differences between groups in terms of reported affective responses to child misbehaviour. Results are discussed in relation to previous research and relevant theoretical literature. Implications for clinical practice and directions for future research are suggested.

description: In this paper, we develop a notion of controllability for hypergraphs via tensor algebra and polynomial control theory. Inspired by uniform hypergraphs, we propose a new tensor-based multilinear dynamical system representation, and derive a Kalman-rank-like condition to determine the minimum number of control nodes (MCN) needed to achieve controllability of even uniform hypergraphs. We present an efficient heuristic to obtain the MCN. MCN can be used as a measure of robustness, and we show that it is related to the hypergraph degree distribution in simulated examples. Finally, we use MCN to examine robustness in real biological networks.

title: Vanadium interaction with FCC catalysts
Creators: name: Sarginson, James Stanley
Publisher: name: The Open University
Year: 1997

description: Fluidised cracking catalysts, which contain a form of zeolite-Y as the main catalytically active component, are widply used commercially for the conversion of crude oil into more profitable product streams. During the cracking reaction, these catalysts are contaminated with vanadium which has a marked effect on the crystallinity of the zeolite-Y component and, as a consequence, activity and selectivity for hydrocarbon processing is degraded. The purpose of this work has been to carry out a detailed investigation, on the laboratory scale, of the effect of vanadium contaminatioil on both commercial and model rare earth ion-exchanged zeolite-Y catalysts. Vanadium contamination was achieved using a standard (Mitchell) method and catalysts were subject to treatment conditions similar to those found in the regenerator part of a fluidised catalytic cracking unit using a specially constructed furnace. Investigations of the solid state chemical reactions between vanadium and rare earth compounds, both in the presence and absence of silica and alumina support materials typical of those found in commercial catalysts, extend the study. Extensive use is made of magic-angle-spinning nuclear magnetic resonance spectroscopy (51V and 27Al), X-ray powder diffraction and surface area measurements for sample characterisation. The apparatus for surface area measurements was constructed during the course of the work.

It is suggested that the reduction in crystallinity of rare earth ion-exchanged zeolite-Y in the presence of vanadium is associated with the removal of rare earth ions from the cage structure of the zeolite. The extent of this process depends upon the details of the treatment conditions and important factors are identified. The observation of the formation of LaVO4 in a range of hydrothermally treated lanthanum ion-exchanged zeolite-Y samples supports the proposed model.
Analysis of the functions and the promoter structures of B-cell translocation gene-2 in rat cortical neurons
Creators: name: Huang, Alan Lo-Chin
Publisher: name: University of British Columbia
Year: 2011

description: Previously data from out lab have shown that BTG2 is up-regulated in both in vitro and in vivo ischemic models. We hypothesize that BTG2 may play a neuro-protective role following glutamate-mediated activation of NMDAR, and that this neuro-protection depends on the collaboration of various transcription factors and cis-acting elements that are found on the BTG2 promoter. To determine the function of BTG2 , BTG2 was either over-expressed or reduced in rat cortical neurons, and treated with either NMDA or oxygen glucose deprivation (OGD). Over-expression of BTG2 reduced NMDA-induced cell death, as measured by LDH assay, and reduced activation of Caspase 3. In addition, CyclinDl mRNA level was significantly increased following NMDA treatment in cells with reduced BTG2 expression by siRNA. Thus, BTG2 appeared to have a neuro-protective function, possibly through down-regulation of CyclinDl expression. To better understand the mechanism that regulated BTG2 expression, we studied the BTG2 promoter by cloning various lengths of BTG2 promoter into a luciferase expression vector. The role of two specific cis-acting elements, a putative P53 binding element P53RE (-53/-94) (-53 to -94 relative to ATG) and a GAGA box, were investigated. While the isolated P53RE (-537-94) sequence functioned as a cis-activating and NMDA inducible element, it became repressive in the context of BTG2 promoter. Removal of P53RE (-53A94) and/or GAGA box not only increased the BTG2 promoter activity, but also made the promoter inducible to NMDA. Consistently, reduction of P53 expression with P53 siRNA led to a significant increase in basal BTG2 expression. Immuno-coprecipitation results showed that the P53 and the GAGA box binding protein were associated together. Taken together, our results suggest that P53 may associate with GAGA box binding protein to form a complex to repress BTG2 expression. A hypothetical mode of action is then proposed, showing that binding of P53 to the P53RE (-53/-94) may activate GAGA box caused suppression, which becomes dominant for BTG2 expression. This mode illustrates a possible mechanism that an transactivating factor P53 and its cis-activating binding site can be turned into a suppressor depending on the location of P53 binding site and the transcriptional regulator(s) P53 associated with.

description: Extremely asymmetrical scattering (EAS) is a highly resonant type of Bragg scattering with a strong resonant increase of the scattered wave amplitude inside and outside the grating. EAS is realized when the scattered wave propagates parallel to the grating boundaries. We present a rigorous algorithm for the analysis of non-steady-state EAS, and investigate the relaxation of the incident and scattered wave amplitudes to their steady-state values. Non-steady-state EAS of bulk TE electromagnetic waves is analyzed in narrow and wide, slanted, holographic gratings. Typical relaxation times are determined and compared with previous rough estimations. Physical explanation of the predicted effects is presented.

description: Sugarbeet production costs varied considerably across farms and regions in the United States on both a per-acre and per-ton basis, according to a U.S. Department of Agriculture survey. Conducted in 2000, the survey asked about production and financial information relating to the 2000 sugarbeet crop. The average cost of producing a ton of sugarbeets in the U.S. was $37.30 in 2000, ranging from $15.40 to more than $60. Yields, input use, irrigation, farm size, and farm location were the major factors affect- ing cost levels. The cost per ton of producing sugarbeets generally declined as farm size increased. Lower cost growers tended to be in the Red River Valley, which typically pro- duces 50 percent of U.S. sugarbeets. Farms in the region tended to be larger than most (averaging 1,675 total acres with 329 acres of beets). Most high-cost and small family farms producing sugarbeets were in the Great Plains region. These farms tended to be less diversified than farms in other regions and contributed less to sugarbeet production. At the average price of $34.20 per ton in 2000, 88 percent of U.S. sugarbeet producers were able to cover their operating costs, 74 percent were able to cover their operating and ownership costs, and 35 percent were able to cover their total (economic) costs.

description: In der deutschen Bodenkunde besagt die allgemein anerkannte Hypothese zur Lessivégenese, dass Lessivés auf weichseleiszeitlichen Sedimenten im norddeutschen Tiefland ausschließlich im Holozän entstanden seien, mit einer Hauptphase der Tonverlagerung im Atlantikum. Vornehmlich systematisch-mikromorphologische Untersuchungen an Braunerde-Lessivés aus Decksand über Geschiebelehm im norddeutschen Tiefland führen zu einer verbesserten Vorstellung über die chronologische Abfolge pedogenetischer Prozesse seit dem Beginn des Spätglazials. Es wird nachgewiesen, dass sowohl im Spätglazial, als auch im Holozän Tonverlagerung stattfand. Durch in Bt-Schmitzen inkorporierte Toncutane ist eine spätglaziale Tonverlagerung belegt, da die Entstehung dieser Schmitzen auf periglaziale Umlagerungsprozesse zurückgeführt werden kann. Ungestörte Toncutane neben Toncutanfragmenten zeigen nachfolgende holozäne Tonverlagerung an.

Paläomagnetische Datierung hochgelegener Sand-Kies-Terrassen der Weser

description: An der Oberweser wurden drei Vorkommen altpleistozäner Terrassensedimente paläomagnetisch untersucht, um eine Datierung nach der Polarität der Remanenzen vorzunehmen. Bei Fürstenberg wechselt in der nach dem Schema von Rohde (1989) drittältesten pleistozänen Weserterrasse die Polarität. In der vermutlich gleichen Terrasse wurde bei Wahmbeck normale Polarität gefunden, dagegen war die erwartete normale Polarität in einer mutmaßlich jüngeren Terrasse bei Gewissenruh nicht ganz eindeutig nachzuweisen. Daraus folgt, daß der Polaritätswechsel nicht mit Sicherheit der Matuyama/Brunhes-Epochengrenze 700000a B.P. zugeordnet werden kann, sondern auch dem Beginn des Jaramillo-Events vor 970000 a entsprechen könnte. Die drittälteste Terrasse ist also spätestens im Cromer-Glazial A entstanden, vielleicht auch schon am Ende des Menap. Sie ist mit der „älteren Hauptterrasse" (tR4) am Rhein zu korrelieren.

description: The U.S. dairy industry underwent dramatic restructuring during the last 50 or so years. Key structural features of the dairy industry are the quantity of milk produced and the location, number, size, and organization of dairy farms. The questions of where, how much, and by whom milk is produced are important from both a national and a regional perspective. The structure of milk production defines the potential direction of the industry. Dairy farms continue to grow, become more concentrated in certain regions, and become more specialized in producing milk. However, small traditional dairy operations remain scattered around the country.

Effects of rotational disruption on the evolution of grain size distribution in galaxies

Year: 2020
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Interstellar dust grains can be spun up by radiative torques, and the resulting centrifugal force may be strong enough to disrupt large dust grains. We examine the effect of this rotational disruption on the evolution of grain size distribution in galaxies. To this goal, we modify our previous model by assuming that rotational disruption is the major small-grain production mechanism. We find that rotational disruption can have a large influence on the evolution of grain size distribution in the following two aspects especially for composites and grain mantles (with tensile strength $\sim 10^7$ erg cm$^{-3}$). First, because of the short time-scale of rotational disruption, the small-grain production occurs even in the early phase of galaxy evolution. Therefore, even though stars produce large grains, the abundance of small grains can be large enough to steepen the extinction curve. Secondly, rotational disruption is important in determining the maximum grain radius, which regulates the steepness of the extinction curve. For compact grains with tensile strength $\gtrsim 10^9$ erg cm$^{-3}$, the size evolution is significantly affected by rotational disruption only if the radiation field is as strong as (or the dust temperature is as high as) expected for starburst galaxies. For compact grains, rotational disruption predicts that the maximum grain radius becomes less than 0.2 $μ$m for galaxies with a dust temperature $\gtrsim 50$ K.

description: We propose S=+1 baryon interpolating operators, which are based on an exotic description of the antidecuplet baryon like diquark-diqaurk-antiquark. By using one of the new operators, the mass spectrum of the spin-1/2 pentaquark states is calculated in quenched lattice QCD at $β=6/g^2=6.2$ on a $32^3\times48$ lattice. It is found that the $J^P$ assignment of the lowest $Θ(uudd \bar s)$ state is most likely $(1/2)^-$. We also calculate the mass of the charm analog of the $Θ$ and find that the $Θ_c(uudd \bar c)$ state lies much higher than the $DN$ threshold, in contrast to several model predictions.

Exarationstiefen würmeiszeitlicher und älterer Gletscher in Südbayern (Trennung eisvorbelasteter und nicht eisvorbelasteter Sedimente aufgrund der seismischen Geschwindigkeiten)

description: Die seismischen Geschwindigkeiten quartärer Ablagerungen in den Moränengebieten und Trogtälern Südbayerns erlauben eine Zweiteilung in eisvorbelastete und nicht eisvorbelastete Sedimente. Es sind hierbei Geschwindigkeitserniedrigungen durch fehlende Wassersättigung (Kies über dem Grundwasserspiegel und Seeton mit organischen Bestandteilen) und Geschwindigkeitserhöhungen durch Verfestigung im Kies, Grundmoränen und großen Tiefen zu berücksichtigen. Nach den refraktionsseismischen (und geoelektrischen) Messungen und einigen Bohrungen sind die alpinen Trogtäler der Iller, Loisach und Isar mit 100 bis 500m mächtigem Quartär aufgefüllt, das in eine relativ geringmächtige post- bis spätglaziale Überdeckung (10 bis 30m) und in z. T. sehr mächtige, eisvorbelastete Sedimente (50 bis 500 m) aufgeteilt werden kann. Der Tiefenschurf der Würmgletscher war gering und beschränkte sich im wesentlichen auf die frühwürmglazialen Schotter. Im Gegensatz hierzu stehen die 100 bis 300 m tiefen Becken im Fels der Trogtalsohlen, die von Gletschern früherer Eiszeiten geschaffen wurden. Im Bereich randlicher Moränenhochflächen und größerer Schotterterrassen in den alpinen Talräumen wurden 100 bis 150 m eisvorbelastete Sedimente in Glazialfurchen, in Becken und auf Trogtalschultern nachgewiesen, die einen noch geringeren Tiefenschurf des Würmgletschers erkennen lassen. Größere Mächtigkeiten spät- und postglazialer Sedimente (50 bis 100 m) wurden in alpinen Nebentälern und im Saalachtal gefunden. Sie werden z. T. auf einen größeren Tiefenschurf des Würmgletschers vor Felsbarrieren und z. T. auf eine fluviatile Ausräumung im letzten Interglazial zurückgeführt, so daß in letzterem Fall die Würmgletscher keine mit den heutigen vergleichbaren Sedimentmächtigkeiten antrafen. Im Alpenvorland liegen große, nicht von den Würmgletschern erodierte Schotterfelder (über mit Seeton verfüllten, glazial-erosiv geschaffenen Becken) und große Seetonbecken mit 100 bis 300 m mächtigen spät- bis postglazialen Seetonen. Nach den vielen Beispielen der geringen Exaration der Würmgletscher ist eine glaziale Ausräumung von älteren Sedimenten dieser Mächtigkeiten unwahrscheinlich. Es wird angenommen, daß diese Becken bei Ankunft der Würmgletscher nur teilweise mit Sedimenten aufgefüllte Seen waren.

An analytical result is derived for the minimum probability of errors in deciding whether the state of a quantum system is either a given pure state or a uniform statistical mixture of any number of mutually orthogonal states. The result is applied to two-qubit states, and the minimum error probabilities achievable by collective and local measurements on the qubits are compared.

description: The competing $^{22}$Ne($α,γ$)$^{26}$Mg and $^{22}$Ne($α,n$)$^{25}$Mg reactions control the production of neutrons for the weak $s$-process in massive and AGB stars. In both systems, the ratio between the corresponding reaction rates strongly impacts the total neutron budget and strongly influences the final nucleosynthesis. The $^{22}$Ne($α,γ$)$^{26}$Mg and $^{22}$Ne($α,n$)$^{25}$Mg reaction rates was re-evaluated by using newly available information on $^{26}$Mg given by various recent experimental studies. Evaluations of The evaluated $^{22}$Ne($α,γ$)$^{26}$Mg reaction rate remains substantially similar to that of Longland {\it et al.} but, including recent results from Texas A\&M, the $^{22}$Ne($α,n$)$^{25}$Mg reaction rate is lower at a range of astrophysically important temperatures. Stellar models computed with NEWTON and MESA predict decreased production of the weak branch $s$-process due to the decreased efficiency of $^{22}$Ne as a neutron source. Using the new reaction rates in the MESA model results in $^{96}$Zr/$^{94}$Zr and $^{135}$Ba/$^{136}$Ba ratios in much better agreement with the measured ratios from presolar SiC grains.

description: The average cost of producing a hundred pounds (cwt) of rice was $6.00 for U.S. producers surveyed in 2000, ranging from about $2 per cwt to more than $10. Producers in the lowest quartile of production costs averaged $3.99 per cwt compared with $8.94 for producers in the highest quartile. Regional differences in production practices, farm characteristics, and growing conditions were major influences on production costs among rice producers. More than half of the low-cost farms were located in the Arkansas Non-Delta, the largest rice region. Most high-cost farms were in California and the Gulf Coast regions. Three-quarters of rice production was concentrated on large and very large farms, categories that included nearly two-thirds of all rice farms, but the link between size of enterprise and production costs for rice is weaker than for other commodities. At the marketing-year average price of $5.61 per hundredweight, 78 percent of rice farms were able to cover operating costs and 43 percent covered both their operating and ownership costs of rice production in 2000. After accounting for Government payments, nearly all rice farms (97 percent) were able to cover operating costs in 2000, and about 84 percent were able to cover both operating and ownership costs.

description: Zum ersten Mal wird von authentischer Seite ausführlicher über die Ergebnisse einer seit 7 Jahren im Gebiete der nördlichen Frankenaib durchgeführten paläontologisch-urgeschichtlichen Grabung berichtet. Das in einer Höhlenruine bei Hunas (ca. 40 km östlich von Nürnberg) erschlossene vielgliederige Schichtenprofil reicht vom Würm über das Riß-Würm-Interglazial bis in das Riß zurück. Diese Datierung kann sich nicht allein auf eine reiche Ausbeute an Saugetierresten stützen, sondern findet ihre weitere Untermauerung auch durch die petrographisch-pedologische Untersuchung des Sedimentmaterials. Besondere Bedeutung erlangt der Fundplatz schließlich durch die Entdeckung von insgesamt über 250 ortsfremden Silices, die aus nicht weniger als 5 verschiedenen Niveaus des Riß-Würm und des Riß stammen.

description: We present an overview and statistical analysis of the data included in WEBDA. This database includes valuable information such as coordinates, rectangular positions, proper motions, photometric as well as spectroscopic data, radial and rotational velocities for objects of open clusters in our Milky Way. It also contains miscellaneous types of data like membership probabilities, orbital elements of spectroscopic binaries and periods of variability for different kinds of variable stars. Our final goal is to derive astrophysical parameters (reddening, distance and age) of open clusters based on the major photometric system which will be presented in a follow-up paper. For this purpose we have chosen the Johnson UBV, Cousins VRI and Stroemgren uvbybeta photometric systems for a statistical analysis of published data sets included in WEBDA. Our final list contains photographic, photoelectric and CCD data for 469820 objects in 573 open clusters. We have checked the internal (data sets within one photometric system and the same detector technique) and external (different detector technique) accuracy and conclude that more than 97% of all investigated data exhibit a sufficient accuracy for our analysis. The way of weighting and averaging the data is described. In addition, we have compiled a list of deviating measurements which is available to the community through WEBDA.

title: Managing ourselves: young people, soap opera and technologies of self-government
Creators: name: Stewart, Michael Patrick James

description: This study examines two television soap operas and their consumption by a select group of teenagers. The soap operas in question, Neighbours and Home and Away, are produced in Australia and watched by large audiences in the UK. The study's broadest aim is to discover the nature of the relationship between the programmes and their teenage viewers. In order to meet this aim, the study combines textual analysis and audience research. Following a review of the textual analysis of soap opera, Neighbours and Home and Away are examined in detail as texts. The audience study is then introduced and located. The empirical study involved tape-recording interviews with groups of 13-16 year olds in one Edinburgh High School, and with individual teenagers in their own homes. In total, 50 teenagers were interviewed. The recurring findings of the audience study are analysed in detail. The final two chapters of the thesis contextualize the findings and conclusions of the textual and audience studies. A selective genealogy is provided which theoretically locates Neighbours and Home and Away and their consumption as cultural practices in self-government. It is argued that the two programmes should be understood as integral parts of a broad but specific arena for learning. It is argued that interviewees use Neighbours and Home and Away as cultural resources. They learn how to conduct themselves in intimate and social relationships, and, in particular, learn how to practise and reconstruct their gendered selves. It is argued that the model of analysis elaborated is valuable because: it best explains the specific nature of Neighbours and Home and Away and their consumption; it provides a way of moving beyond something of an orthodoxy in soap opera analysis; and it avoids the binary logic of some recent arguments about popular culture and social change.
Decoherence in a driven three-level system

description: Dissipation and decoherence, and the evolution from pure to mixed states in quantum physics are handled through master equations for the density matrix. Master equations such as the Lindblad equation preserve the trace of this matrix. Viewing them as first-order time-dependent operator equations for the elements of the density matrix, a unitary integration procedure can be adapted to solve for these matrix elements. A simple model for decoherence preserves the hermiticity of the density matrix. A single, classical Riccati equation is the only one requiring numerical handling to obtain a full solution of the quantum evolution. The procedure is general, valid for any number of levels, but is illustrated here for a three-level system with two driving fields. For various choices of the initial state, we study the evolution of the system as a function of the amplitudes, relative frequencies and phases of the driven fields, and of the strength of the decoherence. The monotonic growth of the entropy is followed as the system evolves from a pure to a mixed state. An example is provided by the $n=3$ states of the hydrogen atom in a time-dependent electric field, such degenerate manifolds affording an analytical solution.

description: Predictions for the ability of 21-cm interferometric experiments to discriminate Epoch of Reionization (EoR) signal models are typically limited by the simplicity of data models, whereby foreground signals and characteristics of the instrument are often simplified or neglected.To move towards more realistic scenarios, we explore the effects of applying more realistic foreground and instrument models to the 21cm signal, and the ability to estimate astrophysical parameters with these additional complexities. We use a highly-optimized version of \textsc{21cmFAST}, integrated into \textsc{21cmMC}, to generate lightcones of the brightness temperature fluctuation for Bayesian parameter estimation. We include a statistical point-source foreground model and an instrument model based on the Murchison Widefield Array (MWA) scaled in observation time to have an effective sensitivity similar to the future Square Kilometre Array (SKA). We also extend the current likelihood prescription to account for the presence of beam convolution and foregrounds, the 2-Dimensional Power Spectrum (PS), and the correlation of PS modes. We use frequency bands between 150 and 180 MHz to constrain the ionizing efficiency ($ζ$), the minimum virial temperature of halos ($T_{\mathrm{vir}}$), the soft X-ray emissivity per unit Star Formation Rate (SFR) ($L_X/SFR$ ), and the X-ray energy threshold ($E_0$). We find that the inclusion of realistic foregrounds and instrumental components biases the parameter constraints due to unaccounted for cross-power between the EoR signal, foregrounds and thermal noise. This causes estimates of $ζ$ to be biased by up to $5σ$ but the estimates of $T_{vir}$, L$_X$/SFR and E$_0$ remain unaffected and are all within $1σ$.

description: Total costs of producing milk in 2000 ranged from an average of $11.58 per hundredweight (cwt) of milk sold in the Fruitful Rim-West region to $18.23 per cwt in the Eastern Uplands. Milk producers in the West had a significant cost advantage over producers in other regions in 2000 because their operations were much larger. Operations with 500 or more milk cows had significantly lower total operating and ownership costs, indicative of the economies of size experienced by larger operations. Also, differences in animal performance, feed efficiency, and labor efficiency were critical in determining whether producers were in the low- or high-cost group for producing milk. These findings were based on the 2000 Agricultural Resource Management Survey (ARMS), the most recent national survey of milk producers.
