Study of Three Potential Variables that May Impact the Maximum Shear Force and Shear Variation During the Growth and Transport of Mixed Sex Broilers Grown in Commercial Poultry Houses
Temperature conditions during the transportation to the processing facility of commercial broilers have a direct impact on the meat texture, specifically maximum shear force and shear variation of cooked breast meat. Analysis of a calendar year of flock data (N=346), reveals that the largest impact of transport conditions, specifically temperature, is on the standard deviation of the flocks range of cooked shear values. The optimal transport temperature that yields broiler breast meat with average flock minimum shear and standard deviation values is approximately 60°F. The shear values for flocks at or near 60°F are on average 1 kg less than during temperatures less than 40°F. The location of the test was not subject to an extreme number of high temperature days preventing reporting the impact of high transport temperatures on meat texture. Chemical analysis of the raw Pectoralis Major (PM) muscle revealed no significant correlation between key minerals and the maximum shear force of the cooked PM muscle. There was a weak correlation of 8% between calcium and maximum shear force. The analysis was intended to lead further tests around intentional water chemistry modifications that would have a positive impact on meat texture. Based on the lack of correlation between minerals found in the raw tissue and cooked meat texture no further actions were pursued.
Cortisone accumulations in the flight feathers are a proven indication of the stress history of the bird. Ultra high performance gas liquid chromatography (UHPGLC) detectible levels of cortisone in the flight feathers were found to range from 2 to 8 ppb in a limited number of samples. Norepinephrine levels ranged from 220 ppb to 1872 ppb. The highest levels of norepinephrine were found in the section of the broiler house at the service entry point. This section of the house also had the lowest sample shear and shear variation of the four sections samples. This may indicate a potential relationship between chronic stresses and improved cooked meat texture
Economic Regulation in the United States: The Constitutional Framework
The United States of America is well-known (and occasionally well-liked or loathed) as the world\u27s largest free-market capitalist nation. Indeed, many assume that since the United States for more than two centuries has had an economic system based on liberal principles, Adam Smith\u27s invisible hand of capitalism must have been embedded in the United States Constitution from the beginning of the American republic. Yet government at all levels in the United States has historically exercised significant regulation of economic and commercial activity-regulation inconsistent with laissez-faire capitalism. The purpose of this article is to consider several questions: (1) what are the constitutional sources of governmental authority in the United States to regulate economic activity?; (2) what are the differences in regulatory powers between the federal and state levels of government?; and (3) what are the limits on the regulatory powers of government in the United States? I should emphasize that in this article I do not intend to advocate for or against government regulation as the proper policy in any specific area; instead, I intend to explore the circumstances under which regulatory policies chosen by policymakers are consistent with the Constitution
DXA-derived body composition and jump mechanical performance in sub-elite rugby union players
The purpose of this study was to investigate the associations of body composition, force and velocity on squat jump height and countermovement jump height in male sub-elite university rugby union players. Seventeen male sub-elite university rugby union players performed a countermovement jump (1kg) and squat jumps using ascending loads of 1kg, 20kg, 40kg and 60kg on one single testing session at the beginning of the season. Linear force-velocity associations and body composition using dual x-ray absorptiometry (DXA) were derived, and the following variables were acquired: total body less head (TBLH) lean mass (kg), legs lean mass (kg), TBLH body fat %, TBLH fat mass (kg), theoretical maximal force (N/kg) and theoretical maximal velocity (m•s-1). The players TBLH body fat % had a statistically significant correlation with the countermovement jump height 1kg (r= -0.723, p= 0.001), squat jump height 1kg (r= -0.608, p= 0.010), squat jump height 20kg (adjusted r2= 0.238, p= 0.027) and squat jump height 40kg (adjusted r2= 0.207, p= 0.038). TBLH fat mass also influenced the countermovement jump height 1kg (r= -0.736, p= <0.001), squat jump height 1kg (r= -0.683, p= -0.003), squat jump height 20kg (adjusted r2= 0.292, p= 0.015), squat jump height 40kg (adjusted r2= 0.212, p= 0.036) and theoretical maximal velocity (r= -0.503, p= 0.039). However, TBLH lean mass, leg lean mass, theoretical maximal force and theoretical maximal velocity had no statistically significant association on the countermovement jump or any of the squat jump loading conditions. This suggests that reducing the amount of TBLH fat mass and TBLH body fat % will improve jump performance, although having more overall mass and lean mass is not necessarily advantageous for improving jump performance. Therefore, the present study provides foundational data for future research to further investigate the associations between body composition, force, velocity and jump height in male rugby union players

Is the Sevier Desert Reflection of West-Central Utah a Normal Fault?
A prominent west-dipping reflection that can be traced in seismic-reflection profiles over an area of 7000 km2 beneath the Sevier Desert basin of west-central Utah is generally referred to as the Sevier Desert detachment and is widely regarded as one of the best examples of an upper-crustal low-angle normal fault. The absence of evidence for fault-related deformation in drill cuttings and core from two industry boreholes that intersect this feature casts doubt on the fault interpretation. The existing interpretation is based mainly on the observation that high-angle normal faulting is restricted largely to Tertiary sedimentary and volcanic rocks above the reflection. An alternative explanation is that the high-angle faults are related to the withdrawal of early deposited lacustrine salt, which even today is as much as 2 km thick. Reevaluation of the seismic data suggests that the Sevier Desert reflection consists of two spatially and genetically distinct segments: a shallow segment here interpreted as an unconformity between Paleozoic and Tertiary strata and a fortuitously aligned deeper segment that is traceable to mid- and lower-crustal levels and that appears to represent a thrust fault related to the Cretaceous Sevier orogeny
Micropalaeontology reveals the source of building materials for a defensive earthwork (English Civil War?) at Wallingford Castle, Oxfordshire
Microfossils recovered from sediment used to construct a putative English Civil War defensive bastion at Wallingford Castle, south Oxfordshire, provide a biostratigraphical age of Cretaceous (earliest Cenomanian) basal M. mantelli Biozone. The rock used in the buttress – which may have housed a gun emplacement – can thus be tracked to the Glauconitic Marl Member, base of the West Melbury Marly Chalk Formation. A supply of this rock is available on the castle site or to the east of the River Thames near Crowmarsh Gifford. Microfossils provide a unique means to provenance construction materials used at the Wallingford site. While serendipity may have been the chief cause for use of the Glauconitic Marl, when compacted, it forms a strong, almost ‘road base’-like foundation that was clearly of use for constructing defensive works. Indeed, use of the Glauconitic Marl was widespread in the area for agricultural purposes and its properties may have been well-known locally
GREEN EXERCISE AND CARDIOVASCULAR HEALTH: QUANTITATIVE EVIDENCE FROM A COMMUNITY CONSERVATION INTERVENTION IN THE UK
This paper aims to add to the fledgling body of work pertaining to the cardio-vascular benefits of self-motivated activity in naturalistic settings. Collecting results from a longitudinal study of a regional community conservation intervention in the UK, it is found that - across a wide range of age groups – simple engagement with a set of everyday horticultural tasks induces the exact levels of exercise that the medical and sport sciences define as optimal for the maintenance of everyday baseline fitness. It is further contended, in line with prior literature, that such capital-free initiatives, designed to improve a local social environment can, thereby, improve the core heath of individuals who may be averse to more conventional gym-type environments

“What If You Don’t Have a Library School?” Ethical Considerations for a Summer Internship at an Academic Library
Enabling professional working experiences for library and information science (LIS) graduate students is always rewarding. With this chapter, the authors will reflect on the operation, collaborative processes, and results of an academic library’s summer internship program. Ethical aspects related to ensuring intern pay, along with individual goal-based learning in a real workplace and the integrity of professional status, will provide insights for others looking to plan or implement similar programs
Benefit nature, benefit self, & benefit others: older adults and their volunteer experiences of engagement in a conservation themed urban park
This paper, utilizing a qualitative methodology, offers further insight into the concept of restorative natural environments by investigating the experiences of five retired and semi- retired volunteers (mean age 65.6 years) involved with a community conservation themed project in an urban park in the north of England, United Kingdom. The volunteers were purposely selected based on their long-term engagement with the specific conservation project. The study was comprised of data collected through interviews and a focus group in the park setting at various timelines throughout the project. Thematic analysis identified three overarching themes: perceived health benefits from participation in a nature based activity; self-reported enhancements to personal, social and community capital; and motives for initial engagement and sustained participation. Various factors relating to how volunteer participation was sustained were highlighted, including: empowerment, social connectedness, access and purposefulness, as well as a non-pressurized activity— with implications for the design of similar community-based ‘green exercise’ interventions. Findings further suggest that involvement in conservation-themed volunteering appears to bestow ‘green transformational’ outcomes for the individual, group and community, manifested by perceived enhancements to personal, social and community capital, as well as overall health and well being. Green transformations induced positive outcomes, such as assisting individuals make the transition into retired life; establishing new social networks; enhancing mental health; contributing to the renewal of the park; and the establishment of a new ‘Friends of the Park’ group to help fund raise for future small-scale projects. Projects and initiatives of this ilk may therefore be beneficial in respect of promoting public health improvements for individuals attracted to more unorthodox and natural approaches
