Click here for the English version of this report

La dispersion des polluants des émissions de cheminées de toit dans la couche limite est fortement influencée par la présence de bâtiments avoisinants et la topographie locale. Il est donc très difficile d’évaluer précisément les concentrations dans le panache sur différentes surfaces de bâtiments. Les polluants émis par une cheminée de toit peuvent présenter des risques pour la santé des occupants des bâtiments s’ils se réintroduisent dans le bâtiment duquel ils émanent ou s’ils pénètrent dans un bâtiment voisin par des ouvertures se trouvant sur différentes surfaces de bâtiments. La plupart …

La prédiction de la dispersion des émissions polluantes de cheminées de toit en milieu urbain est extrêmement complexe, tout particulièrement en présence de bâtiments voisins. Le comportement du panache dépend des caractéristiques du vent, mais il est aussi lourdement influencé par l’environnement. Il se peut ainsi que les effluents émis par une cheminée de toit se réintroduisent dans le bâtiment émetteur ou dans un bâtiment adjacent, exposant du coup les occupants à d’éventuels problèmes de santé. La conception et l’implantation optimales de cheminées d’évacuation pour limiter une telle réingestion au niveau …

Safe Motherhood Training For Rural Health Care Workers In Odukpani Local Government Area Of Cross River State, Nigeria, Josephine Etowa, Ekaete Asuquo, Ani Etokidem

School of Nursing & Midwifery, East Africa

Maternal mortality remains a challenge in developing countries which bear 99% of global maternal deaths (WHO, 2014). Nigeria, India, Pakistan, Afghanistan and Ethiopia carry more than 50% of the global burden of maternal mortality. According to the UNDP Human Development Report (2014), Nigeria’s maternal mortality ratio of 630 per 100,000 live births ranks among the highest in Africa. Two countries accounted for one third of all global maternal deaths: India at 17% (50 000) and Nigeria at 14% (40 000) (WHO, 2014).. Archibong and Aghan (2010) found that hospital based maternal mortality ratio in Cross River state was 1,513.4per 100,000 …

Supplementing Cow-Calf Pairs Grazing Smooth Bromegrass, Jason M. Warner, Annie J. Doerr, Galen E. Erickson Erickson, Rick J. Rasby, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A three-year study evaluated supplementing ethanol co-products mixed with low-quality forage to cow-calf pairs grazing smooth bromegrass as a method to replace grazed forage intake. Supplementing a 30:70 modified distillers grains plus solubles:cornstalks mixture reduced estimated grazed forage intake by approximately 40%. Doubling the stocking rate and supplementing did not impact cow or calf performance. A summer supplementation program designed to reduce grazed forage intake is a viable strategy for increasing stocking rate if forage for grazing is limited.

Effect Of Post-Weaning Management And Age At Weaning On Calf Growing And Finishing Performance, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

The impact of post-weaning management system and calf age at weaning on growing and finishing performance was evaluated. During the growing phase, cattle in the fast-track system had improved intake, gain, and feed conversion. Although initial finishing weight was similar between systems, slow-track cattle had greater intake, gain, final body weight, and carcass weight. While the impact of age at weaning was negligible, the improvement in finishing performance for slow-track cattle demonstrates the value of different management systems.

Estimation Of British- And Continental-Specific Heterosis Effects For Birth, Weaning, And Yearling Weight In Cattle, Lauren N. Schiermiester, R. Mark Thallman, Larry A. Kuehn Kuehn, Matthew L. Spangler

Nebraska Beef Cattle Reports

Heterosis, assumed proportional to expected breed heterozygosity, was calculated for 6,834 individuals with birth, weaning, and yearling weight records from Cycle VII of the U.S. Meat Animal Research Center Germplasm Evaluation Program. Heterosis was further estimated by proportions of British x British (BxB), British x Continental (BxC), and Continental x Continental (CxC) crosses. Estimates of BxB, BxC, and CxC heterosis were significant for weaning and yearling weight. This study illustrated that differences among biological types exist and provide an opportunity to utilize specific breeds and exploit heterosis in a crossbreeding system to achieve production goals.

The Effects Of Source And Amount Of Nitrite On Quality Characteristics Of All-Beef Frankfurters, Eric Miller, Chad G. Bower, Amy L. Redfield Redfield, Gary A. Sullivan

Nebraska Beef Cattle Reports

In an effort to meet consumers’ demand for foods with more natural ingredients, processors have begun manufacturing meat products cured with natural nitrite sources. The objective of this study was to evaluate the quality characteristics of all-beef frankfurters cured with traditional or alternative sources of nitrite and using equivalent amounts of nitrite. Frankfurters cured with alternative sources of nitrite had a slightly darker, less red exterior and slightly more yellow interior than those containing sodium nitrite. No differences were observed for pH or water activity. Both curing methods can be used to manufacture all-beef frankfurters with similar characteristics when using …

Stocking Rate Effects On Forage Nutrient Composition In Early Summer Pastures, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, K. H. Jenkins, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Nebraska Sandhills upland range pastures were used to measure the effectsof stocking rate on forage nutrient content in early summer pastures. Stocked pastures had lower CP, in vitroorganic matter digestibility, forage availability, and higher NDF compared with ungrazed pastures. Clipped samples of current year growth had greater CP and in vitro organic matter digestibility than diet samples. Observed results indicate early season grazing decreasesdiet nutrient content and forage availability compared with ungrazed pastures, suggesting that cattle were consuming both current and previous year growth.

Comparison Of Commercial Lick Tubs To Distillers Grains Supplementation For Calves Grazing Corn Residue, Mandi Jones, James C. Macdonald, Galen E. Erickson Erickson, Terry J. Klopfenstein, Kathleen R. Brooks, Dirk B. Burken, Robby Bondurant, Andrea K. Watson

Nebraska Beef Cattle Reports

Steer calves grazing irrigated corn residue were supplemented dried distillers grains plus solubles (DGS) or allowedcontinuous access to a commercial lick tub. Dried DGS was fed at 2.94 lb/steer/day and the lick tubs were consumed at 2.04 lb/steer/day (DM basis). Gain was greater for cattle supplemented with dried DGS (1.36 lb/day) compared to those with access to lick tubs (0.83 lb/day). Supplement efficiency varied between calves receiving dried DGS (46%) and those with continuous access to the lick tub (43%) when expressed on a DM basis. Values for dried DGS supplementation (48%) were not different for supplement efficiencyon an OM …

Nutrient Digestibility And Ruminal Ph Of Finishing Diets Containing Dry Milling Byproducts With And Without Oil Extraction, Melissa L. Jolly-Breithaupt, Adam L. Shreck, Jana L. Harding Harding, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

A metabolism trial was conducted to determine the effects of corn oil removal in condensed distillers solubles (CDS) and modified distillers grains plus solubles (MDGS) on nutrient digestibility and ruminal pH. Oil removal had no impact on DM, OM, or NDF digestibility in steers fed CDS or MDGS. However, steers fed de-oiled CDS had a lower fat digestibility than steers fed normal CDS. Average ruminal pH was lower for steers fed de-oiled MDGS than for steers fed normal MDGS, however no difference within CDS was observed.

Effect Of Distillers Grains Plus Solubles And Monensin Supplementation On Grazing Steers, Tyler L. Hasenauer, Terry J. Klopfenstein, James C. Macdonald Donald, Robby G. Bondurant, Dirk B. Burken

Nebraska Beef Cattle Reports

Yearling steers rotationally grazing smooth bromegrass were individually supplemented monensin at 0 or 200 mg with modified distillers grains plus solubles (MDGS) at .05, 0.4, 0.6, and 0.8% BW. Cannulated steers continuously grazing smooth bromegrass were assigned randomly to one of two treatments: 0.4% BW MDGS supplementation with 0 or 200 mg monensin. Monensin did not affect ADG of steers supplemented MDGS ≥ 0.4% BW. Steers supplemented with monensin had a decreasein estimated average forage intakefrom 16.16 lb to 14.75 lb/OM daily.

Effects Of Processing Treated Corn Stover And Distillers Grains On Performance Of Growing Cattle, Jana L. Harding, Curtis J. Bittner, Dirk B. Burken Burken, Galen E. Erickson, James C. Macdonald

Nebraska Beef Cattle Reports

A study evaluated the effects of replacinga diet consisting of 60% corn stover, 18% solubles, and 18% distillers grains with a complete pelleted feed containing calcium oxide (CaO) treated corn stover and distillers grains on growing cattle performance. The pelleted feed was either pair-fed to the control treatment or fed ad libitum. There were no differences in ending BW, ADG, or F:G between the control and pair-fed treatment. Feeding the pellet ad libitum resulted in greater DMI and ADG; however, the cattle had greater F:G. The pellet has 98% the feeding value of the control treatment.

Effects Of Replacing Corn With A Pelleted Treated Corn Stover And Distillers Grains On Intake And Total Tract Digestibility Of Finishing Diets, Jana L. Harding, Melissa L. Jolly-Breithaupt, Galen E. Erickson Erickson, James C. Macdonald

Nebraska Beef Cattle Reports

A digestion study was conducted to evaluate the effects of replacing dry-rolled corn (DRC) with a pelleted feed containing treated corn stover, solubles, and distillers grains (DDG). Replacing DRC with the pelleted feed had no effect on intakes. Similarly, total tract digestibilities of DM, OM, or NDF were not affected by dietary treatment. There was a tendency for differences in average ruminalpH between treatments; however, proportions of acetate, propionate, and butyrate were not impacted. It was concluded that the DRC could be replacedwith a pelleted stover and distillers in the finishing diet without altering total tract digestion.

Effect Of 300 Or 400 Mg Daily Of Ractopamine Hydrochloride On Growth Performance And Carcass Characteristics Of Finishing Steers During The Last 14, 28, Or 42 Days, Curtis J. Bittner, Dirk B. Burken, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson, Nathan A. Pyatt

Nebraska Beef Cattle Reports

The effects of ractopamine hydrochloride (Optaflexx®) dosage (0, 300, and 400 mg/head/day) and duration (14, 28, or 42 days) on growth performance were evaluated in feedlot finishing diets. Feeding 300 mg of Optaflexx for 28 or 42 days increased live final BW by 13 and 29 lb, while feeding Optaflexx at 400 mg resulted in 27 or 24 lb increases relative to 0 mg steers, respectively. Feeding 300 mg of Optaflexx for 28 or 42 days would suggest 11.1 or 16.6 lb improvements in HCW, while feeding 400 mg of Optaflexx would suggest 19.7 or 20.7 lb heavier carcasses compared …

Genetic Parameter Estimates For Calving Difficulty And Birth Weight In A Multibreed Population, Cashley M. Ahlberg, Larry A. Kuehn, R. Mark Thallman Thallman, Stephen D. Kachman, Matthew L. Spangler

Nebraska Beef Cattle Reports

Eighteen breeds were utilized to estimate genetic parameters for birth weight and calving difficulty on first-parity females. Birth weight and calving difficulty were moderately heritable allowing for genetic selection to decrease calving difficulty. Genetic correlation estimates were positive between direct effects for birth weight and calving difficulty. This work will serve as the foundation for estimating across-breed EPD for calving difficulty in the U.S.

Activation Of T-Cell Protein-Tyrosine Phosphatase Suppresses Keratinocyte Survival And Proliferation Following Uvb Irradiation, Hyunseung Lee, Liza D. Morales, Thomas J. Slaga, Dae Joon Kim

School of Medicine Publications

Chronic exposure to UV radiation can contribute to the development of skin cancer by promoting protein-tyrosine kinase (PTK) signaling. Studies show that exposure to UV radiation increases the ligand-independent activation of PTKs and induces protein-tyrosine phosphatase (PTP) inactivation. In the present work, we report that T-cell PTP (TC-PTP) activity is stimulated during the initial response to UVB irradiation, which leads to suppression of keratinocyte cell survival and proliferation via the down-regulation of STAT3 signaling. Our results show that TC-PTP-deficient keratinocyte cell lines expressed a significantly increased level of phosphorylated STAT3 after exposure to low dose UVB. This increase corresponded with …

School of Medicine Publications

Obesity is a chronic metabolic disorder that may also lead to reduced white matter integrity, potentially due to shared genetic risk factors. Genetic correlation analyses were conducted in a large cohort of Mexican American families in San Antonio (N = 761, 58% females, ages 18–81 years; 41.3 ± 14.5) from the Genetics of Brain Structure and Function Study. Shared genetic variance was calculated between measures of adiposity [(body mass index (BMI; kg/m2) and waist circumference (WC; in)] and whole-brain and regional measurements of cerebral white matter integrity (fractional anisotropy). Whole-brain average and regional fractional anisotropy values for 10 major …

Shifting Our Focus From Retribution To Social Justice: An Alternative Vision For The Treatment Of Pregnant Women Who Harm Their Fetuses, April L. Cherry

Journal of Law and Health

The ways in which society responds to pregnant women whose behavior purportedly harms their fetuses can be explored from a variety of legal vantage points. This article argues that the criminal law model currently used is ineffective. The assignment of criminal liability to pregnant women is often rooted in fetal personhood and maternal deviance discourse. Criminal law solutions fail because they fail to take into account the fact that maternal behavior is often the result of a myriad of the social and economic conditions over which pregnant women have little or no control. The criminal law model, therefore, simply punishes …

Occupation-Based Leisure Interventions For Individuals With Spinal Cord Injury, Jaclyn Swangstue, Whitney Josephson

Occupational Therapy Capstones

The purpose of this scholarly project was to provide occupational therapists with a practical guide for implementing occupation-based leisure interventions for individuals with spinal cord injury (SCI). In recent years, the occupational therapy (OT) profession has seen a shift from a biomechanically driven paradigm back to the occupation-centered practice from which OT is rooted. Though the definition and mission of OT involves the use of occupation-centered interventions, this vision is not always evident within current treatment plans for people with a SCI diagnosis. Research has indicated that leisure participation is essential for this population due to the physical benefits and …

Implications Of Huntington's Disease On Daily Living: An Educational Tool And Guide For Occupational Therapists Treating Individuals With Huntington's Disease, Jacquelin Jones, Megan Thompson

Occupational Therapy Capstones

Huntington’s disease (HD) is a neurodegenerative disease that can cause stress on the individual as well as their family members and caregivers. Due to the rareness of Huntington’s disease (HD), it is common that professionals are often at a loss when treating patients who have it. Dawson et al. (2004) discussed the need for individualized and client-centered care for those individuals diagnosed with HD, as well as providing practical supports for those diagnosed and their families. Furthermore, a major challenge to assessment and intervention is the complexity of the symptoms present with HD. Etchgary (2011) found in her study that …

Faculty Publications & Research of the TUC College of Pharmacy

Francisella tularensisis a facultative intracellular pathogen, and is the causative agent of a fatal human disease known as tularemia. F. tularensis is classified as a Category A Biothreat agent by the CDC based on its use in bioweapon programs by several countries in the past and its potential to be used as an agent of bioterrorism. No licensed vaccine is currently available for prevention of tularemia. In this study, we used a novel approach for development of a multivalent subunit vaccine against tularemia by using an efficient tobacco mosaic virus (TMV) based delivery platform. The multivalent subunit vaccine was formulated …

Pseudomonas Aeruginosa-Induced Bleb-Niche Formation In Epithelial Cells Is Independent Of Actinomyosin Contraction And Enhanced By Loss Of Cystic Fibrosis Transmembrane-Conductance Regulator Osmoregulatory Function, Amber L. Jolly, Desire Takawira, Olufolarin O. Oke, Sarah A. Whiteside, Stephanie W. Chang, Emily R. Wen, David J. Evans

Faculty Publications & Research of the TUC College of Pharmacy

The opportunistic pathogen Pseudomonas aeruginosa can infect almost any site in the body but most often targets epithelial cell-lined tissues such as the airways, skin, and the cornea of the eye. A common predisposing factor is cystic fibrosis (CF), caused by defects in the cystic fibrosis transmembrane-conductance regulator (CFTR). Previously, we showed that when P. aeruginosa enters epithelial cells it replicates intracellularly and occupies plasma membrane blebs. This phenotype is dependent on the type 3 secretion system (T3SS) effector ExoS, shown by others to induce host cell apoptosis. Here, we examined mechanisms for P. aeruginosa-induced bleb formation, focusing on its …
