Northern Pike (Esox Lucius) Population Characteristics And Relations To Recruitment In Hackberry Lake, Nebraska, Joseph J. Rydell, Jeffrey C. Jolley, Quinton E. Phelps, David W. Willis

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Knowledge of the population structure of northern pike (Esox lucius), an important recreational and toplevel piscivore, is essential to Nebraska Sandhill lakes management. We collected a sample of adult northern pike from Hackberry Lake in June and July of 2004. Proportional stock density (PSD) was 98 (95% CI = ± 3) and relative stock density of preferredlength fish (RSD-P) was 40 (95% CI = ± 9). Northern pike were aged using sagittal otoliths, and fish from the 1993 to the 2002 year classes were present in our population sample. Age-frequency histograms revealed relatively consistent recruitment of northern pike, …

Exercise And Diabetes Influence Antioxidant Activity And Gene Expression In Female Rats, Janet E. Steele, Karynn E. Kucera, Cory A. Ciccone, Mary E. Connealy

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The goal of this study was to examine the influence of exercise training and type I diabetes on the activity of aconitase and superoxide dismutase (SOD), on levels of reduced glutathione (GSH), on the expression of genes responsible for glutathione synthesis (Gclc, g-glutamylcysteine synthase; Gss, glutathione synthetase), and on the expression of genes responsible for the formation of two potassium channels (Kcnd2, I_to; KCNQl, I_Ks) in cardiac muscle. Forty female Sprague-Dawley rats were divided into four groups: sedentary controls, sedentary diabetics, trained controls, and trained diabetics. Diabetes was induced via streptozotocin injection, and training consisted of …

The Meaning Of Place And Community In Contemporary Educational Discourse, John Siskar, Paul Theobald

Journal of Inquiry and Action in Education

Place and community are terms used with ever more frequency in discussions, reports, and research related to education, yet there is little agreement related to what these terms mean. This article examines the concepts of place and community in an attempt to bring more clarity to the role they may play in educational theory and, ultimately, educational policy.

Measurement Of Nutrient Availability In Feedstuffs For Florida Pompano And Development Of Formulated Diets For Pompano Aquaculture, Craig Gothreaux

LSU Master's Theses

Consistently high market demand combined with low commercial catches have made Florida pompano, Trachinotus carolinus, one of the highest valued finfish from the Gulf of Mexico. Economic incentive has spurred interest in pompano culture since the 1950s, yet the body of nutritional research on pompano is still sparse. This study was conducted to measure the apparent digestibility of nutrients among a selection of common feed ingredients, and determine the optimum dietary protein level for juvenile Florida pompano at a fixed protein-to-energy ratio, in order to formulate nutritionally complete, cost-effective diets. The four ingredients tested in the digestibility trial were soybean …

Dwelling And The Woman Artist In The Tenant Of Wildfell Hall, Rebecca L. Lupold

Graduate Student Theses, Dissertations, & Professional Papers

This thesis addresses the Heideggerean notion of dwelling in Anne Brontë’s The Tenant of Wildfell Hall by analyzing the different ways the novel’s protagonist, Helen Huntingdon, adapts to the harsh, sublime landscape of Wildfell Hall and the subsequent relationship that develops between her and Gilbert Markham. Escaping her violent and abusive husband, Helen flees to Wildfell Hall and uses her skills as an artist to support both herself and her son. In the first chapter, late-eighteenth and early-nineteenth century aesthetics of the sublime and the picturesque are evaluated in relation to the aesthetic spaces of the novel. Helen enjoys an …

A Study Of Somatic Cell Counts In The Milk Of Holstein-Friesian Cows Managed In Mediterranean Climatic Conditions, Atakan Koç

Turkish Journal of Veterinary & Animal Sciences

Somatic cell counts (SCC) in the milk of Holstein-Friesian (HF) cows were determined by direct microscopic SCC technique. For a two-year period, milk samples were collected monthly from buckets during the morning and evening milkings at 4 different dairy farms. In total, 1,464 SCC readings from 88 HF cows were analyzed by using repeated measures. Herd, lactation month, parity, milking time, and herd interaction effects on SCC were statistically significant (P < 0.05). The average SCC in milk per herd was between 296,483 and 688,811 cells/ml. SCC in milk increased as parity increased. The average SCC in milk from evening milking was about 83,165 cells/ml higher than from morning milking. Improving milking management, reducing stress, providing extra care during the first month of lactation, and milking at a uniform interval will help to decrease SCC in milk and the prevalence of mastitis.

Clostridium Perfringens Type D Enterotoxaemia In The Chinkara Deer (Gazella Bennettii), Ahrar Khan, Imtiaz Ali, Iftikhar Hussain, Nazir Ahmad

Turkish Journal of Veterinary & Animal Sciences

During an enterotoxaemia outbreak, 9 out of 11 (82%) Chinkara deer (Gazella bennettii) died; 5 animals died of peracute disease, whereas acute death was observed in 4 animals. The case fatality rate was 100%. Clinical signs, including high temperature, depression, anorexia, abdominal pain, greenish watery diarrhoea, and respiratory distress, were recorded in the affected deer. Post-mortem examinations of the affected animals revealed muscular and serosal haemorrhages, hydroperitoneum, hydrothorax, and hydropericardium. Severe haemorrhages were also observed in the small intestine, colon, and kidneys. Histopathologically, haemorrhagic enterocolitis, pulmonary oedema, accumulation of proteinaceous fluid in alveoli, perivascular oedema, and interstitial and intertubular haemorrhages …

Anticoagulant Rodenticide Intoxication In Animals – A Review, Ivan Valchev, Rumen Binev, Veska Yordanova, Yordan Nikolov

Turkish Journal of Veterinary & Animal Sciences

The newest measures for the control of harmful rodent populations are from the anticoagulant rodenticide group, which are divided into 2 subgroups: first and second generations, and indandione derivatives. Non-target organisms are potentially at risk of direct consumption of baits (primary hazard) and of eating poisoned rodents (secondary hazard). Anticoagulant rodenticides inhibit the enzyme vitamin K-dependent carboxylase and thus impair the reactivation of vitamin K1, indirectly affecting physiological blood coagulation. The diagnosis is made on the basis of clinical signs (massive hemorrhages), laboratory findings, and especially the changes in coagulation markers (APTT, PT, TT, PCT, ACT, FDPs, and PIVKA). The …

Genetic Parameters For Direct And Maternal Effects And Estimation Of Breeding Values For Birth Weight In Brown Swiss Cattle, Muammer Ti̇lki̇, Mustafa Saatci, Mehmet Çolak

Turkish Journal of Veterinary & Animal Sciences

Variance components, genetic parameters, and breeding values for birth weight in Brown Swiss cattle reared in Bahri Dağdaş International Agricultural Research Institute were estimated by REML-BLUP procedures using MTDFREML computer programme. Six different animal models were fitted for the trait ranging from a simple to the most comprehensive model. The most detailed model (model 6) provided the best fit to the used dataset. Heritability was higher in the model without maternal effect. Although maternal effect had a significant place for the data, environmental effect due to dam was not important. Heritability (h^2), maternal heritability (m^2), and the genetic correlation between …

Prediction Of Postpubertal Reproductive Potential According To Prepubertal Body Weight, Testicular Size, And Testosterone Concentration Using Multiple Regression Analysis In Kıvırcık Ram Lambs, Özkan Elmaz, Serdal Di̇kmen, Ümi̇t Ci̇ri̇t, Hidir Demi̇r

Turkish Journal of Veterinary & Animal Sciences

The relationship between the prepubertal body weight, testicular size, testosterone concentration, and postpubertal reproductive function was investigated in Kıvırcık ram lambs. The body weight, testicular size, and testosterone concentration were measured every 20 days between 60 and 420 days of age. Semen was collected from the ram lambs at 7, 8, 9, 10, 11, 12, 13 and 14 months of age. Data obtained were analyzed by best subsets regression model. We determined that body weight, scrotal circumference, testicular length, and testosterone levels in the early prepubertal period (days 80, 100, and 120), when combined with each other, allow the determination …

Coxiella burnetii causes Q fever (Coxiellosis) in humans and animals worldwide. The present study was carried out to determine the seroprevalence of Q fever among stray cats in 3 providences (Ankara, Niğde, and Kayseri) in Central Anatolia, Turkey. A total of 143 sera from stray cats were examined for the presence of IgG against C. burnetii phase II antigen by indirect fluorescent antibody test (IFAT). Seven out of the 143 (4.9%) stray cats were seropositive for Q fever, with titers of 1:64 to 1:256. Seroprevalences in Ankara, Niğde, and Kayseri provinces were 1.6%, 7.4%, and 8.3%, respectively. This is the …

Relevance For Food Safety Of Applications Of Nanotechnology In The Food And Feed Industry, Iona Pratt, Catherine Adley, Gordon Chambers, Wayne Anderson

Articles

The application of nanotechnology in the food and feed industry offers many potential benefits for both consumers and manufacturers.The ultrafine dimensions of nanoparticles, and consequently their very large surface area, enable them to function more effectively than conventional macro-scale structures in many applications. Nanotechnology is however a relatively new area of science and the benefits and risks associated with its use in the food and feed industry are not fully understood at this time.This brings with it new challenges in ensuring the safety of food and feed that has been produced with the aid of nanotechnology. This report provides an …

The Effects Of Traditional Grazing Practices On Upland (Yayla) Rangeland Vegetation And Forage Quality, Bi̇nali̇ Çomakli, Mahmut Daşci, Ali̇ Koç

Turkish Journal of Agriculture and Forestry

A seminomadic animal raising system, known as ''yaylacılık'' in Turkish, is one of the best ways of using upland rangelands, particularly in rough terrain regions. Three rangeland sites were selected to determine the spatial effect of summer grazing distribution on botanical composition, canopy coverage, soil aggregate stability, and forage nutrient content in these range sites. On average, grass covered 61.09% of the total land in site I, 67.04% and 57.40%, respectively, in sites II and III. Legume covered 11.61%, 13.67%, and 18.05%, respectively, of the total land in sites I, II, and III. Other families covered 27.30%, 19.29%, and 24.55% …

Could And Should America Have Made An Ottoman Republic In 1919?, Paul D. Carrington

Faculty Scholarship

Numerous Americans, perhaps especially American lawyers, have since the 1780s presumed to tell other peoples how to govern themselves. In 2006, that persistent impulse was once again echoed in an address to the American Bar Association by a Justice of the Supreme Court. The purpose of this essay is to question the wisdom of this evangelical ambition, especially when the form of instruction includes military force. It is draws on Spreading America's Word (2005) and directs attention to the hopes of American Protestant Zionists to make a democratic republic in Ottoman Palestine. It suggests that chances were better in 1919 …

What's In A Name? A Philosophical Critique Of 'Civil Unions' Predicated Upon A Sexual Relationship, Gerard V. Bradley

Journal Articles

'Civil unions' represent a fragile political armistice, not lasting peace. My interest in 'civil unions' is not, however, political. It is philosophical. I argue in this paper that 'civil unions' are wrong - and should be abandoned in law - because they are incoherent. This article is about what's in the name, marriage. My thesis is that the reason why same-sex couples may not marry defeats the case for 'civil unions' defined (even in part) as a sexual relationship. To reasonably deny these couples access to marriage is to deny them access to 'civil unions'. Conversely, to create 'civil …

"Excluding Religion": A Response, Richard W. Garnett

Journal Articles

In a thorough and thoughtful article, Excluding Religion, Prof. Nelson Tebbe asks "whether the government may select religious entities for exclusion from its support programs?" and concludes that, sometimes, it may. "The government," he contends, "need not remain neutral toward religion in its support programs[.]"

In this short response to Tebbe's paper, I first suggest that the reasons Tebbe offers for such exclusion - including "promoting equal citizenship for members of minority faiths . . . , fostering community concord, [and] respecting taxpayers' freedom of conscience", are not particularly strong. Next, I turn to the various "limits" that Tebbe …

Judicial Enforcement Of The Establishment Clause, Richard W. Garnett

Journal Articles

This paper is the author’s contribution to a roundtable conference, held in October of 2008 at Notre Dame Law School, devoted to Prof. Kent Greenawalt’s book, Religion and the Constitution: Establishment and Fairness. It is suggested that Greenawalt’s admirably context-sensitive approach to church-and-state questions might lead us to think that the best course for judges is to find (somehow) some bright-line, on-off “rules” and “tests”, constructed to identify and forbid the most obvious violations of the Religion Clause’s core (whatever that is), and to give up on -- or, perhaps, “underenforce” -- the rest.

Symposium: Stare Decisis And Nonjudicial Actors: Introduction, Amy Coney Barrett

Journal Articles

This essay is as an introduction to a symposium on stare decisis and nonjudicial actors. It frames the questions explored in the symposium by pausing to reflect upon the variety of ways in which nonjudicial actors have, over time, registered their disagreement with decisions of the United States Supreme Court. Both public officials and private citizens have battled the Court on any number of occasions since its inception, and historically, they have employed a diverse range of tactics in doing so. They have resisted Supreme Court judgments. They have denied the binding effect of Supreme Court opinions. They have sought …

The Structure Of Classical Public Law, Barry Cushman

Journal Articles

Duncan Kennedy's The Rise and Fall of Classical Legal Thought circulated in manuscript for three decades before it was formally published in 2006. This essay reviews the book's treatment of Classical public law, focusing on its two principal contributions to the historiography of the subject: the concept of legal consciousness, and the structural analysis of constitutional doctrine.

Do Churches Matter? Towards An Institutional Understanding Of The Religion Clauses, Richard W. Garnett

Journal Articles

In recent years, several prominent scholars have called attention to the importance and role of First Amendment institutions and there is a growing body of work informed by an appreciation for what Professor Balkin calls the infrastructure of free expression. The freedom of expression, he suggests, requires more than mere absence of government censorship or prohibition to thrive; [it] also require[s] institutions, practices and technological structures that foster and promote [it]. The intuition animating this scholarship, then, is that the freedom of expression is not only enjoyed by and through, but also depends on the existence and flourishing of, certain …

The Evangelical Debate Over Climate Change, John Copeland Nagle

Journal Articles

In 2006, a group of prominent evangelicals issued a statement calling for a greater response to climate change. Soon thereafter, another group of prominent evangelicals responded with their own statement urging caution before taking any action against climate change. This division among evangelicals concerning climate change may be surprising for a community that is usually portrayed as homogenous and as indifferent or hostile toward environmental regulation. Yet there is an ongoing debate among evangelicals regarding the severity of climate change, its causes, and the appropriate response. Why? The answer to this question is important because of the increasing prominence of …

Gene Targeting In Adult Rhesus Macaque Fibroblasts, Daniel T. Meehan, Mary Ann Zink, Melissa Mahlen, Marilu Nelson, Warren G. Sanger, Shoukhrat M. Mitalipov, Don P. Wolf, Michel M. Ouellette, Robert B. Norgren

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: Gene targeting in nonhuman primates has the potential to produce critical animal models for translational studies related to human diseases. Successful gene targeting in fibroblasts followed by somatic cell nuclear transfer (SCNT) has been achieved in several species of large mammals but not yet in primates. Our goal was to establish the protocols necessary to achieve gene targeting in primary culture of adult rhesus macaque fibroblasts as a first step in creating nonhuman primate models of genetic disease using nuclear transfer technology.

RESULTS: A primary culture of adult male fibroblasts was transfected with hTERT to overcome senescence and allow …

Effects Of Induced Acute Phase Response In Ewes On Early Embryo Survival, Tina Lynn Dow

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early pregnant ewes, 5/6 day post coitus (dpc) were used as a model to study early embryonic loss via gram-positive bacterial infections, such as mastitis. Ewes 5/6 dpc were injected with a gram-positive bacteria cell wall component, peptidoglycan-polysaccharide (PG-PS), to induce an innate immune system acute phase response (APR). The induction of the APR and its reactant molecules, such as cytokines and acute phase proteins (APP), were initiated to study their effects on embryonic loss. Twenty Suffolk ewes were synchronized for estrus and bred by fertile rams. At 4 dpc ewes were anesthetized and catheters were surgically placed in the …

Non-Apoptotic Roles Of Caspase-8 And Caspase-2, Brooke M. Helfer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Caspases are proteolytic enzymes involved in committing apoptosis, but through the studies of knockout phenotypes in mice and Drosophila , it has been speculated that caspases might possess additional non-apoptotic functions.;We have found non-apoptotic functions for caspase-8 in both normal and tumor cell lines. Specifically, we found that caspase-8 promotes cell migration, adhesion, and Rac activation. Subsequently, we also found that caspase-8 interacts with the p85 subunit of PI3K. Accompanying stimulation of motility with epidermal growth factor the phosphorylation of caspase-8 on tyrosine-380 is induced and this phosphorylation allows for p85 interaction, cell migration, adhesion, and Rac activation. Caspase-8 also …
