title: Electronic Feeding Doors for Individual Feeding of Group Housed Sheep Compared to Individual Housing and Feeding or Group Housing and Feeding
Creators: name: Lane, Ronald J.
Publisher: name: Utah State University
Year: 1983

description: Thirty-six mature purebred cheviot ewes and 36 polypaysired wether lambs were used in two separate experiments to determine the usefulness of an electronic feeding door as contrasted with traditional feeding situations. The sheep were stratified by weight into three management categories; group housing and feeding (G+G), individual housing and feeding (1+1), or group housing and individual feeding (G+1) using an electronic feeding door. The weight stratification formed a light and a heavy weight class resulting in a 3x2 factorial design. Two different training procedures were used to arrive at a generalized 14-day training sequence that does not require physical handling of the sheep. No differences were observed in learning behavior with older ewes or with sufficiently large lambs.
During a 56 day immediate pre-slaughter feeding period for the lambs, average daily gain was .23 kg, average daily feed consumption was 2.12 kg, feed efficiency was 9.08, carcass dressing percent was 43.6, yield grade was 3.3, and all but three lambs graded USDA Choice. Management category had no significant effect on these performance measures, with the exception that (G+1) lambs consumed more (P
Weight class (light vs. heavy) had no effect on the changes that occurred during the trial although significant differences existed in regards to the magnitude of the actual body weights and condition scores. Heavy weight class lambs remained consistently heavier than light lambs throughout the trial.
A significant effect of week was observed over the last eight weeks on both weight gain and feed consumption. Shearing during week one and a change in caretaker during weeks four and five were possible explanations for the observed differences due to time.
title: Effect of Rain Leaching on Chemical Composition of Alfalfa Hay
Creators: name: Garcia de Hernandez, Mercedes M.
Publisher: name: Utah State University
Year: 1981

description: Yield and chemical changes of second-cutting alfalfa hay treated with artificial rain were determined in a 2 x 3 x 2 factorial experiment. Factors were 2 stages of maturity (1 late vegetative; 2 early bloom), 3 levels of artificial rain applied (1 =no rain; 2 =low or approximately 5 mm; 3 =high or approximately 20 mm), and 2 times of applying artificial rain (1 = when drying forage was 40-60% dry matter; 2 =when drying forage was 60-75% dry matter). Thirty samples of alfalfa were collected at the 2 stages of maturity when the alfalfa was fresh cut, pre-sprinkled, pre-baled and prefeeding. Alfalfa samples were analyzed for dry matter, nitrogen, ash, plant cell walls, cellulose, hemicellulose, lignin, total lipids and acid insoluble ash. Available carbohydrates and soluble ash were calculated.
Yield of dry matter increased with advancing maturity. Plant cell content fraction was lowered but plant cell wall constituents were increased with advancing stage of growth.
Artificial rain significantly affected chemical composition of alfalfa hay. Available carbohydrates, soluble ash and ash decreased due to the effect of leaching. Total lipids was slightly reduced by leaching, while protein content was not changed. Cellulose, lignin and cell wall fractions of alfalfa hay increased consistently under the effect of artificial rain. Sprinkling and processing time did significantly change the chemical composition of alfalfa hay. DM and AlA content increased in relation to process.
Interactions among treatment factors were generally nonsignificant. The only significant interactions were maturity-by-artificial rain level effect on available carbohydrate, lipids, cellulose and cell wall.
In general, alfalfa hay treated with artificial rain had a lower nutritive and economic value than when it is not affected by any rain.

title: Comparison of Toxicological Models for Evaluation of Air Pollutants: Response of the Pulmonary Alveolar Macrophage to Hexavalent Chromium
Creators: name: Galvin, Jennifer Baker
Publisher: name: Utah State University
Year: 1981

description: This study was designed to accomplish two primary objectives: (1) to compare two test methods commonly used to evaluate toxicity of inhaled air pollutants, and (2) to observe the response as measured by each of the methods, of pulmonary alveolar macrophages exposed to 2μg hexavalent chromium.
The first method evaluated featured use of intratracheal injections to simulate live inhalation exposures, and the second required exposure of macrophages cultured on petri plates. Pulmonary alveolar macrophages harvested from Long Evans rats were used. The two cell function parameters measured in the evaluations were chemiluminescence and oxygen consumption (which was determined for cells at rest and during phagocytosis). These two tests have been shown to be sensitive indicators of macrophage damage. Results of CL output and oxygen consumption revealed the two methods were significantly different.
Evaluation of macrophages from live animals treated with CrO3 or CaCrO4showed no differences between their respective untreated controls as determined by measurement of their chemiluminescence production or of oxygen consumption rates.
Alveolar macrophages that were cultured in media during treatment with the same two forms of hexavalent chromium showed statistically significant differences from untreated controls.
These comparisons indicate that choices of investigative toxicological models influence interpretation of data recorded.
Mutual information in time-varying biochemical systems

description: Cells must continuously sense and respond to time-varying environmental stimuli. These signals are transmitted and processed by biochemical signalling networks. However, the biochemical reactions making up these networks are intrinsically noisy, which limits the reliability of intracellular signalling. Here we use information theory to characterise the reliability of transmission of time-varying signals through elementary biochemical reactions in the presence of noise. We calculate the mutual information for both instantaneous measurements and trajectories of biochemical systems for a Gaussian model. Our results indicate that the same network can have radically different characteristics for the transmission of instantaneous signals and trajectories. For trajectories, the ability of a network to respond to changes in the input signal is determined by the timing of reaction events, and is independent of the correlation time of the output of the network. We also study how reliably signals on different time-scales can be transmitted by considering the frequency-dependent coherence and gain-to-noise ratio. We find that a detector that does not consume the ligand molecule upon detection can more reliably transmit slowly varying signals, while an absorbing detector can more reliably transmit rapidly varying signals. Furthermore, we find that while one reaction may more reliably transmit information than another when considered in isolation, when placed within a signalling cascade the relative performance of the two reactions can be reversed. This means that optimising signal transmission at a single level of a signalling cascade can reduce signalling performance for the cascade as a whole.

description: We express the AdS-Schwarzschild black-hole configuration in coordinates such that the boundary metric is of the FLRW type. We review how this construction can be used in order to calculate the stress-energy tensor of the dual CFT on the FLRW background. We deduce the temperature and entropy of the CFT, which are related to the temperature and entropy of the black hole. We find that the entropy is proportional to the area of an apparent horizon, different from the black-hole event horizon. For a dS boundary we reproduce correctly the intrinsic temperature of dS space.

Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: Following the successful application of the relativistic heavy quark(RHQ) action to the charmonium and charm-strange meson spectrum, we study here the bottom system to explore the validity of this method in a regime with larger heavy quark momenta. The spectrum is calculated using the same dynamical 2+1 flavor, $24^3\times 64$ domain wall fermion lattice configurations generated by the RBC and UKQCD collaborations and used in the earlier charm study. The 3 parameters in the RHQ action are determined by matching to the experimental bottom-strange meson masses and extrapolated to the chiral limit from three different sea quark masses. We predict the bottomonium mass spectrum and compare it with experiment. A theoretical estimation is also carried out to understand the $O(a^2p^2)$ systematic errors found in the numerical study.

title: An Economic Analysis of Farm Flock Sheep Production in Utah
Creators: name: Beck, Ken
Publisher: name: Utah State University
Year: 1981

description: The purpose of this study was to evaluate the economic aspects of farm flock sheep production in Utah. Using 1979 as a base year, costs and returns were calculated from data obtained from twenty- six Utah farms. Characteristics that typify the states· farm flock sheep production, at this writing, with regard to: 1) the farm flock producers and 2) the farm flock enterprise, were presented.
Various models were dev eloped and examined using Multiple Regression and Linear Programming analytical techniques. Multiple Regression was us ed to estimate the effects that different variables had on the profitability of the sheep enterprise. The most significant variables were found to be: 1) the number o f years each producer has been involved in sheep production and 2) number of years rams are retained for breeding purposes. Linear Programming was used to maximize the relative net returns between : 1 ) a traditional method of farm flock sheep production in Utah. 2) an accelerated production program where three lamb crops are produced in two years, and 3) an intensive program where two lamb crops are produced in one year. The accelerated lambing program producing three lamb crops in two years consistently demonstrated the highest relative net return. Recommendations of future related research were also included.

description: We consider maximally symmetric 3-branes embedded in a six-dimensional bulk spacetime with Lovelock dynamics. We study the properties of the solutions with respect to their induced curvature, their vacuum energy and their effective compactness in the extra dimensions. Some simple solutions are shown to give rise to self-accelerating braneworlds, whereas several others solutions have self-tuning properties. For the case of geometric self-acceleration we argue that the cross-over scale in between four-dimensional and higher-dimensional gravity and the scale of late-time geometric acceleration, fixed by the present horizon size, are related via the conical deficit angle of the six-dimensional bulk solution, which is a free parameter.

Ion chromatographic determination of haloacetates in environmental samples
Creators: name: Wang, F
Publisher: name: University Of Tasmania
Year: 2023

description: A method is reported for the sensitive, simultaneous determination of mono-, di-, and trifluoroacetates by ion chromatography. These species were separated using a Dionex AS17 anion-exchange column employed with a potassium hydroxide gradient (via a Dionex EG40 Eluent Generator) and suppressed conductivity detection. The fluoroacetates were successfully separated from a range of inorganic and organic species likely to be present in environmental samples, in a total analysis time of 35 min (including re-equilibration of the column). Detection limits for mono-, di- and trifluoroacetate were 21, 38 and 36 micrograms/L, respectively, determined using a signal to noise ratio of 3, and were obtained using a sample injection volume of 50 microlitres. Precision was less than 0.83% relative standard deviation for replicate injections performed over a period of 30 days. The method was applied to the determination of MFA, DFA and TFA in river water, carrot baits, urine samples and different kinds of plant material including Bilobum, Calvcinum and Spinosum, and found the concentration range of mono-(MFA), di-(DFA), tri-fluoroacetate (TFA) to be 11-788, 3.5-17 and 0.22-1.2 ppm in wet weight plant samples respectively. Further research was carried out using the Dionex equipment specified above. A comparative study was made of the chromatographic behaviour of nine haloacetic acids mono-(MFA), di-(DFA), tri-fluoroacetate (TFA); mono-(MCA), di-(DCA), trichloroacetate (TCA) and mono-(MBA), di-(DBA), tri-bromoacetate (TBA). The techniques included anion-exchange chromatography with suppressed conductivity and UV detection. All nine haloacetic acids were completely separated under the optimised gradient elution conditions. Using selective detection methods or by pretreating samples with a OnGuard II Ag cartridge, eliminated some interference. The procedure for the simultaneous determination of the nine haloacetic acids was simple and fast. The method detection limits for MFA, DFA, TFA, MCA, DCA, TCA, MBA, DBA, and TBA were 21, 40, 40, 48, 28, 86, 67, 55, and 160 ppb respectively, determined using a signal to noise ratio of 3. Applications of these methods for the determination of haloacetic acids in real soil samples are shown.

description: Due to the growth of milk marketing areas in the Intermountain West, a study was made to determine the most advantageous allocation of producer milk to twelve selected processing demand areas and to calculate location differentials between these same markets. A theoretical determination of location differentials and of the allocation of milk supply areas to processing centers were made using supply-push and demand-pull price alignment models developed by Associated Milk Producers, Inc., for the months of November 1979 and June 1980. Grade A producer mil k from the six member cooperatives of Western Dairymen' s Cooperative, Inc., was used in the study.
From the computed location differentials, a framework was developed from which milk cooperatives in the Intermountain West could use to base future policy decisions.
Sibylline books
Creators: name: Camp, Lance Wallace
Publisher: name: University of British Columbia
Year: 2011

description: The sibylline books, though dismissed by J. G. Frazer* as a "convenient farrago of nonsense", were nevertheless one of the most significant influences in the political and religious life of Rome during the Republic. This study has, as its1 objective, a discussion of the history of these books during the Republic between 753 and 12 B. G. It is based, for the most part, on a discussion of all consultations recorded during this period; emphasis is placed on the reasons for consultation, and, in particular, the nature and influence of the sibylline recommendations. Special importance is attached to consultations whose nature and results reveal the sibylline books as a political instrument manipulated by those who controlled them. In addition, there is discussion of any significant innovations ordered by the books, and special attention is paid to any consultations that appear, from the point of view of their results, extraordinary or unusual. A history of the books during this period also necessitates, to a certain extent, a discussion of the religious college that controlled them. It also requires that a certain amount of attention be paid to religious concerns and innovations associated with the books. However, these topics are important to this study only insofar as they have a direct bearing on the republican history of this religious institution. After an introductory discussion of the origin and nature of the sibylline books, their development and history is divided into three periods falling between the years 753--204, 203--83, and 83--12. Each of these periods is discussed from two points of view. Firstly, a normal pattern of sibylline operation is established; secondly, those consultations which do not fit this normal pattern receive more detailed attention. Consultations of a normal nature are grouped, for each period, according to their initiation and result, whereas extraordinary consultations are considered chronologically. It is shown that the sibylline books were a versatile political instrument throughout this period. There is evidence that their manipulation by political groups reached a notable climax during the second Punic War and remained frequent until the end of the Republic. From the point of view of Roman religion, it is seen that the sibylline books were responsible for many important religious innovations, most of which concerned the importation of non-Italic rites and gods into Roman religion. Finally, it is shown that the sibylline tradition, established during the first three centuries of the Republic, declined gradually and steadily between the end of the second Punic War and the second revision of the books, by Augustus, in 12 B. C. This event in particular marked the end of the sibylline tradition at Rome.

description: Graphene is a relatively new material (2004) made of atomic layers of carbon arranged in a honeycomb lattice. Josephson junction devices are made from graphene by depositing two parallel superconducting leads on a graphene flake. These devices have hysteretic current-voltage characteristics with a supercurrent branch and Shapiro steps appear when irradiated with microwaves. These properties motivate us to investigate the presence of quantum metastable states similar to those found in conventional current-biased Josephson junctions. We present work investigating the nature of these metastable states for ballistic graphene Josephson junctions. We model the effective Washboard potential for these devices and estimate parameters, such as energy level spacing and critical currents, to deduce the design needed to observe metastable states. We propose devices consisting of a parallel on-chip capacitor and suspended graphene. The capacitor is needed to lower the energy level spacing down to the experimentally accessible range of 1-20 GHz. The suspended graphene helps reduce the noise that may otherwise come from two-level states in the insulating oxide layer. Moreover, back-gate voltage control of its critical current introduces another knob for quantum control. We will also report on current experimental progress in the area of fabrication of this proposed device.

description: We propose minimum empirical divergence (MED) policy for the multiarmed bandit problem. We prove asymptotic optimality of the proposed policy for the case of finite support models. In our setting, Burnetas and Katehakis has already proposed an asymptotically optimal policy. For choosing an arm our policy uses a criterion which is dual to the quantity used in Burnetas and Katehakis. Our criterion is easily computed by a convex optimization technique and has an advantage in practical implementation. We confirm by simulations that MED policy demonstrates good performance in finite time in comparison to other currently popular policies.
title: The Economics of Information and Spatial Price Behavior: An Empirical Assessment of Producer's Cattle Prices in the Western Region of the USA: 1973-1981
Creators: name: Juan, Maria Lourdes del Rosario
Publisher: name: Utah State University
Year: 1983

description: This study is an empirical verification of the theories of the economics of information at the cattle producer's market in the U.S. Western Region. Weekly data on producer's price quotations were obtained from CATTLEFAX for 1973 through 1981. The three major objectives of the research are: first, to determine whether price dispersion exists in the cattle producer's market in the Western Region: second, if significant price dispersion are shown to exist, to determine the nature of the regional price distribution; and third, if price dispersion do exist, to determine the implications of the dispersion relative to competitive structure, efficient informational flows, and relative informational content of said distribution.
Price dispersion exists in the cattle producer's market of the Western Region. It is the buyers who "establish" prices and sellers act as price takers. Where heavy trading occurs, information of prices is more efficiently transmitted resulting in a more symmetrical distribution. The composition of the market is relatively stable. however, imperfect information results in splitting the market into high price and low price favoring the better informed.
Utah producers are rational in their pricing decisions. Price dispersion can be attributed to the lag in obtaining price information and asymmetry in efficiency of information gathering.

Year: 1985

description: Forty-eight Holstein cows at Utah State Dairy Farm were blocked statistically according to date of calving, previous milk production, and numbers of lactation at parturition. The cattle were assigned randomly to one of four treatments within blocks. The four treatments included a base ration (control, treatment #1), base ration plus .8% of sodium bicarbonate (treatment #2), base ration plus .4% of magnesium oxide (treatment #3), and base ration plus both .8% of sodium bicarbonate and .4% of magnesium oxide (treatment #4). The research was conducted from February 1983 to November 1984. A formagraph was used to measure milk coagulation parameters and pH was determined.
There was no significant difference in milk coagulation parameters or pH between the control and the buffer treatments. Milk parameters were significantly different in individual cow, week, and milk pH. Milk parameters did not appear to be dependent upon season. Curd firmness was significant in interaction of season and treatment. Significant variations in milk pH were observed in relation to week, season, and individual cow.
Overall treatments, the clotting time, K20, and pH value increased each wee, and A30 decreased each week. The milk parameters and pH in each treatment were significant between weeks except K20 and A30 in treatment #3, and A30 in treatment #2 (p
Somatic cell count was positively correlated with clotting time, K20, and pH and negatively correlated with A30. Milk pH was the most significant and had positive correlation coefficient with clotting time and firming rate and negative correlation coefficient with curd firmness.
title: The Economic Impact of Potential Changes in Federal Grazing Policies on Ranchers in Wayne County, Utah
Creators: name: Jacobson, Kib Elden
Publisher: name: Utah State University
Year: 1981

description: The purpose of this study was to select an area in Utah that was predominantly livestock oriented which used federal lands for livestock grazing, and to develop model ranches exemplifying the typical live-stock operation in the area. These model ranches were then used in a Budget Generator Program (BG) and a Linear Programming framework (LP) to simulate reductions of 25%, 50%, 75% and 100% reductions of BLM land usage. The results were then used to determine income changes, herd size changes, and resource usage in the models as the reductions took place.
The area chosen was Wayne County, Utah because of the dependence of the livestock operators on BLM land for livestock grazing in the winter. Also because the area was predominantly livestock oriented. A group of ranchers from southern Idaho was also included because of their usage of the BLM land in Wayne County.
Kinetic Heterogeneities at Dynamical Crossovers

description: We perform molecular dynamics simulations of a model glass-forming liquid to measure the size of kinetic heterogeneities, using a dynamic susceptibility $χ_{\rm ss}(a, t)$ that quantifies the number of particles whose dynamics are correlated on the length scale $a$ and time scale $t$. By measuring $χ_{\rm ss}(a, t)$ as a function of both $a$ and $t$, we locate local maxima $χ^\star$ at distances $a^\star$ and times $t^\star$. Near the dynamical glass transition, we find two types of maxima, both correlated with crossovers in the dynamical behavior: a smaller maximum corresponding to the crossover from ballistic to sub-diffusive motion, and a larger maximum corresponding to the crossover from sub-diffusive to diffusive motion. Our results indicate that kinetic heterogeneities are not necessarily signatures of an impending glass or jamming transition.

description: Background: Anorexia nervosa (AN) and autism spectrum disorder (ASD) may be phenotypically and etiologically linked. However, due to the absence of prospective studies, it remains unclear whether the elevation of autistic traits in AN is evident in early childhood. Here, we prospectively investigated autistic traits before and after the first diagnosis of AN. Methods: In a population-based sample of 5,987 individuals (52.4% female) from the Child and Adolescent Twin Study in Sweden, parents reported autistic traits at ages 9 and 18. AN and ASD diagnoses were retrieved from the Swedish National Patient Register. In addition, AN diagnoses were ascertained by parent-reported treatment for AN. We compared whether individuals with and without AN differed in autistic traits before the first diagnosis of AN (age 9) and after the first diagnosis of AN (age 18). Results: We did not find evidence for elevated autistic traits in 9-year-old children later diagnosed with AN. At age 18, however, there was a marked elevation in restricted/repetitive behavior and interests, but only in the subgroup of individuals with acute AN. A less pronounced elevation was observed for social communication problems. Conclusions: Coping strategies in individuals with ASD and the somewhat different female ASD phenotype may explain why we did not find elevated autistic traits in children who later developed AN. Alternatively, it is possible that elevated autistic traits were not present prior to the onset of AN, thus questioning the previously reported elevated prevalence of ASD in AN. Future studies should use tailored measurements in order to investigate whether autistic traits in individuals with AN are best conceptualized as an epiphenomenon of the acute AN phase or whether these symptoms indeed represent ASD as a clinically verifiable neurodevelopmental disorder.

description: The properties of the deoxyribonuclease activity in the intestinal mucosa of the rat have been studied. Two DNases were found in a cell-free extract prepared by homogenizing the mucosal tissue in Krebs-Ringer phosphate buffer and then centrifuging the homogenate at 105,000 x g for 60 mins. Resolution and partial purification of these two enzymes were achieved by ion-exchange chromatography on DEAE-cellulose and partition on hydroxylapatite of the cell-free extract or an acetone powder preparation of the enzymes. One of the enzymes was identified as DNase I by its optimum pH (6.5 to 6.8), its requirements for bivalent metals and by its reaction to known DNase I inhibitors such as EDTA, citrate and arsenate. It was also found to be active toward native DNA, and, to a lesser degree, toward heated DNA. The second DNase was shown to be qualitatively different from DNase I. It has an acidic optimum pH (3.5-4.0), does not require activation by bivalent cations and is not inhibited by EDTA, citrate or arsenate. This second DNase activity is therefore of the DNase II type. The linkage specificity of the two enzymes was studied by isolating the products of the reaction and examining them with respect to chain length, base composition of the mononucleotides, relative frequencies of the dinucleotides and base frequencies at the ends of the oligonucleotides. The hydrolysis reaction was carried out under a variety of conditions. When Mg++ was used as the activating ion and native DNA as substrate, DNase I was found to show a preference for the linkages pApC, pApT and pGpT. But when Mn++ was the activator, or when heated DNA was used as substrate in the presence of Mg++, DNase I did not show any significant order of specificity. With regard to DNase II, the enzyme was found to attack native DNA preferentially at the ApCp, GpCp and GpTp bonds. The mechanism of metal activation of intestinal DNase I was also studied. Preliminary experiments showed that the enzyme was inhibited by high concentrations of both metals and DNA. In addition, optimal activation was found to depend on the molar ratio of metal ion to DNA phosphorus. These experiments suggested that the metal-DNA complex is probably the true substrate. Consequently, a rate equation in terms of the metallosubstrate concentration was developed based on the assumption that intestinal DNase I can combine individually and simultaneously with free metal, free DNA and the metal-DNA complex. Data obtained from initial velocity studies carried out at varying concentrations of metal and DNA fitted this rate equation well. On this basis, it was suggested that the enzyme, the metal activator and the DNA substrate combine to form a ternary complex which then dissociates to give the products.

description: The main aim of every organization is to improve performance and productivity, but this is only possible with efficient management techniques and technology that produces results. Thus, the main aim of this study is to analyze the effect of managerial skills and technology adaptation on firm performance and productivity through the mediation channel of process innovation and product innovation using the PLS-SEM technique. The data for this study is collected from 150 managers of manufacturing industrial firms located in Lahore, the second largest city in Pakistan. The present used the purposive sampling technique to achieve the research objectives. The study’s empirical findings reveal that managerial skills and technology adaptation are positively and significantly related to process and product innovation. Indirect and total effects show that managers’ skills, technology adaptation, process innovation, and product innovation are positively and significantly related to the productivity and performance of firms. The present research is focused on the implementation of new technology and innovation.

description: Background Prenatal infections have been proposed as a putative risk factor for a number of psychiatric outcomes across a continuum of severity. Evidence on eating disorders is scarce. We investigated whether exposure to prenatal maternal infections is associated with an increased risk of disordered eating and weight and shape concerns in adolescence in a large UK birth cohort.Methods We used data from the Avon Longitudinal Study of Parents and Children. The primary exposure was maternal experience of infections at any time in pregnancy. Study outcomes were presence of any, monthly or weekly disordered eating at 14 and 16 years of age, and weight and shape concerns at 14 years. We defined the causal effect of the exposure on these outcomes using a counterfactual framework adjusting our analyses for a number of hypothesised confounders, and imputing missing confounder data using multiple imputation.Results In total, 4884 children had complete exposure and outcome data at age 14 years, and 4124 at 16 years. Exposed children had a greater risk of reporting weekly disordered eating at both age 14 [risk difference (RD) 0.9%, 95% confidence interval (CI)-0.01 to 1.9, p = 0.08] and 16 (RD 2.3%, 95% CI 0.6-3.9, p < 0.01), though evidence of an association was weak at age 14 years. Exposed children also had greater weight and shape concerns at age 14 years (mean difference 0.15, 95% CI 0.05-0.26, p < 0.01).Conclusions Exposure to prenatal maternal infection is associated with greater risk of disordered eating in adolescence. This association could be explained by in utero processes leading to impaired neurodevelopment or altered immunological profiles. Residual confounding cannot be excluded.
A LATENT CLASS ANALYSIS OF FEMALE PERPETRATED SEX OFFENSES

Subjects: female perpetrated sex offenses
sexual assault
rape
sexual violence

description: Female perpetrated sexual violence (FPSV) remains an understudied subject in sexual violence research studies. This study provides a comprehensive overview of female perpetrated sex offenses (FPSOs) by utilizing large samples of self-reported and police-reported sexual victimization data. It also provides a comparison of FPSOs and male perpetrated sex offenses (MPSOs) to assess whether gendered offending patterns exist and to evaluate the situational contexts of those offenses to identify practical prevention strategies. Results showed that FPSOs and MPSOs are overwhelmingly similar, albeit with some nuances, suggesting that sexual offending is more gender invariant than is presumed. Common FPSOs and MPSOs included heterosexual rape, heterosexual sexual assault, multi-perpetrator rape, and multi-perpetrator sexual assault. The results of this study challenge existing assumptions about sexual violence and gender. The practical and theoretical implications of these findings are discussed.
title: Effect of Toxaphene on Collagen Synthesis in Fish Tissue: Organ Culture Studies and Prolyl Hydroxylase Activity Assay

description: Toxaphene is reported to cause defects in the collagen of fish. Chronic exposure to toxhaphene weakens the backbone of fish by decreasing the amount of collagen and usually increasing the amount of calcium in the bone which results in a more brittle and fragile bone.
We investigated the possible direct action of toxaphene on collagen synthesis by exposing vertebral and swim bladder organ cultures obtained from unexposed rainbow trout (Salmo gairdneri) fingerlings to the same lot of toxaphene found to cause this defect in vivio. Collagen produced by these organ cultures was measured by: (1) total 3H-proline incorporated into the matrix; (2) 3H-proline released during collagenase digestion of acid-precipitated protein; (3) 3H-hydroxyproline extracted from the acid hydrolysate, and (4) tritiated water produced during the hydroxylation of 4-3H-proline. At a relatively high concentration of toxaphene (2.4 mM) these indices of collagen production were reduced, but this was probably caused by a decrease in tissue viability rather than by a direct affect on collagen synthesis. At 240 μM cellular protein synthesis was reduced. Generally no effects were found at toxaphene concentrations below 240 μM. From these studies it was concluded that toxaphene does not have a direct inhibitory effect upon collagen production at the tissue level.
For comparison to the in vivo were measured. All three of these parameters were significantly reduced in comparison to controls (α = 0.05) in those fish exposed to the highest concentration of toxaphene (200 ng/1). fish exposed to 150 ng/l toxaphene also had reduced prolyl hydroxylase activity. These results indicated that vertebral prolyl hydroxylase activity may be a sensitive indicator of toxaphene exposure in fish, and inhibition of that enzyme may be involved in the mechanism of toxaphene-induced collagen effects.
title: The Development of Methodology for Gas Liquid Chromatographic Determination of Plant Sugars in Maturing Reed Canarygrass

description: This study was concerned with development of chromatographic methods suitable for determination of plant sugars. The resultant methodology was applied to the comprehensive study of plant carbohydrates as they vary during plant growth. Plant cell walls were isolated with boiling water followed by delignification with acid chlorite. The soluble portions were hydrolyzed with 2N sulfuric acid and the total sugars and individual monosaccharides were quantified using gas chromatography and colorimetry. The insoluble residues were hydrolyzed with 72% sulfuric acid followed by dilution with water to 2N and further hydrolysis. The effects of duration of delignification and acid hydrolysis were interpreted in terms of carbohydrate yield monitored colorimetrically and with gas chromatography.
The rapid derivation of sugars was perfected using N-methyl-imidazole as an acetylation catalyst. This catalyst was also employed for the derivatization of lactonized aldonic acids, enabling the gas chromatographic quantitation of uronic acids.
The growth of reed canarygrass was interpreted with empirical and non-empirical methodology. the empirical procedures provided little insightinto plant cell wall composition. The non-empirical methodology which included DMSO extraction and gas-liquid chromatography revealed the possible presence of a branched galactoarabinoxylan and a linear arabinoxylan in reed canarygrass hemicellulose. The presence of β-glucan was also confirmed using selective enzymatic hydrolysis. As the plants matured, the proportion of linear xylan increased. The occurence of galactose, mannose, fucose and rhamnose in cell wall extracts may be the result of acid catalyzed degradations and transformations of other cell wall sugars.
The results revealed the value of chromatography as it is applied to interpretation of plant growth and composition. Gas-liquid chromatography was proposed as a tool for the evaluation of forage digestibility and forage quality.
