To evaluate any associations with morbidity and mortality. Design: Retrospective study. Setting: Three university teaching hospitals and two private referral centers. Animals: Thirty-five client-owned dogs presented with NPPE. Interventions: None Measurements and Main Results: Data collected included patient characteristics, clinical history, clinicopathological abnormalities, radiographic features, treatments and outcome. Median age was 4 months (range 2-90) and median weight was 7.1 kg (range 1.7-37.2). There were many causes of NPPE including leash tugs, near hanging, accidental choking, anatomical obstruction to airflow and purposeful airway obstruction by people. The most common cause of NPPE was accidental choking (40% of cases). Dogs with an anatomical obstruction were older than 24 months. Hypoxemia with an increased alveolar-arterial gradient was common on presentation. The majority of thoracic radiographs (65.7%) showed an alveolar or interstitial pattern in the caudodorsal area as previously described in the literature. Oxygen therapy was administered to 33 (94.3%) dogs. Furosemide was administered to 18 (51.4%) dogs. Median length of hospitalization was 2 days (range 0-14). Twenty-eight (80%) dogs survived to discharge. Seven dogs were mechanically ventilated and only 2 of them (28.6%) 2 survived to discharge. Requirement for mechanical ventilation (p<0.001) was the only parameter associated with mortality. Conclusions: Most cases of NPPE occur in juvenile dogs. Different incidents associated with upper airway obstruction can produce an episode of NPPE. Choking on food or toys and near hanging have not been previously described in the veterinary literature as inciting causes of NPPE. The overall prognosis is good.

The objective of this report is to discuss different methodologies and assessment criteria for the evaluation of the impacts of environmental regulations in the agricultural sector; to identify the relevant environmental regulations administered at the federal, provincial and local levels; and an analytical framework to evaluate the future role of regulations and other policy instruments in achieving the desired social, environmental and economic outcomes. This study is a foundation piece for later phases of multi-year research project to develop strategic environmental policy for sustainable agriculture and environment.

As of August, 2015, 105 youth leaders and leader supervisors from 24 states have completed professional development and many have formed SJS youth groups. In this paper we describe what it takes for a successful implementation of Skynet Junior Scholars in a 4-H setting, ...

Unfortunately, many of these species are not reproducing at high enough levels to sustain populations within zoos. Low reproductive success and high infant mortality are two areas of concern for some of these species. Collecting behavioral data on developmental milestones following successful births can create a database of information to aide animal management to help make more informed decisions during subsequent births. The current study provides valuable information for African elephant calf developmental norms and demonstrates how data on first occurrences, nursing behavior and growth patterns can aide animal management. Data were collected on eleven African elephants (Loxodonta africana) at the San Diego Zoo Safari Park in Escondido, CA of which ten have survived. Results show that on average African elephant calves were standing within 40 minutes, attempte...

This is achieved by the direct geopositioning of the exterior orientation of a digital imaging sensor by use of an integrated Global Positioning System (GPS) receiver and an Inertial Navigation System (INS). A crucial issue to this particular type of aerial mapping is the accuracy, scale, consistency, and speed achievable by such a system. To address these questions, an Applanix Digital Sensor System (DSS) was used to examine its potential for near realtime mapping. Large segments of vegetation along the San Andreas and Cucamonga faults near the foothills of the San Bernardino and San Gabriel Mountains were burned to the ground in the California wildfires of October-November 2003. A 175 km corridor through what once was a thickly vegetated and hidden fault surface was chosen for this study. Both faults pose a major hazard to the greater Los Angeles metropolitan area and a near real-time mapping system could provide information vital to a post-disaster response.

The study aimed to investigate for the first time the prevalence, breed-based risk factors and clinical management of CUD in the general population of dogs under primary veterinary care in England. Of 104,233 dogs attending 110 clinics participating within the VetCompass Programme from January 1(st) to December 31(st) 2013, there were 834 confirmed CUD cases (prevalence: 0.80%, 95% confidence interval (CI) 0.75-0.86). Breeds with the highest prevalence included Pug (5.42% of the breed affected), Boxer (4.98%), Shih Tzu (3.45%), Cavalier King Charles Spaniel (2.49%) and Bulldog (2.41%). Purebred dogs had 2.23 times the odds (95% CI 1.84-2.87, P < 0.001) of CUD compared with crossbreds. Brachycephalic types had 11.18 (95% CI 8.72-14.32, P < 0.001) and spaniel types had 3.13 (95% CI 2.38-4.12, P < 0.001) times the odds for CUD compared with crossbr...

The collision probability and the characteristic methods are considered, and exact and approximated tracking methods to be used in the implementation of geometrical motions and albedo conditions are analyzed. The analysis of the exact boundary-condition treatment is carried out for finite domains and infinite lattices, where periodic trajectories must be used. Albedo-like boundary conditions may be used to approximate exact geometrical motions via spatially piecewise constant and either piecewise constant or discrete angular approximations for the boundary fluxes. We also have examined angular product quadrature formulas and shown that the recently proposed Bickley-Naylor quadratures do not respect particle conservation in the presence of anisotropy of scattering. Numerical examples show that the approximated albedo-type boundary method converges toward the results obtained with the exact boundary treatment. However, because of problems related to the multigroup implementation, numerical extra burden in group iterations prevents the efficient use of approximated boundary conditions for multigroup calculations. Nevertheless, this method remains a candidate of choice for use in multidomain calculations via interface boundary fluxes.
