Aquaculture Industry of Arkansas in 1979-1980

A survey of previous fish farmer certificate holders in Arkansas was conducted during 1979-1980 using renewal questionnaires, telephone conversations, and personal contacts. This survey was compared with similar surveys from preceding years. Approximately 51.0% of 12,372 intensively farmed hectares in 1979-80 were devoted to bait fish production, while 22.9% were utilized in food fish production. Acreage in bait fish, food fish, and fingerling production decreased from 1979 to 1980; however, price increases during this time resulted in a higher total value of the industr

Reconstructing Ancient Lives Using 3D Technology: A Case Study of Pork and Doughboy Point, Belize

3D technology can preserve cultural heritage resources and enhance museum collections and exhibits. Through 3D scanning, an exact digital replica of an artifact is created, which can be printed out or used to create a digital display. For this project, 3D scanning was used to reconstruct ancient Maya lives at Pork and Doughboy Point, Belize. By studying and classifying an inventory of selected artifacts, we were able to determine what activities occurred at the site. goal of this project was to showcase the growing importance of 3D technology in cultural preservation and the variety of ways in which it can be used. Additionally, this project sought to explore the negative and positive aspects of digitization in museum collections, and the feasibility of the implementation of this technology

Influences of Music Genre and Components on Food Perception and Acceptance

Managers of consumer goods companies (i.e., restaurants, grocery stores, and bars) have the potential to effectively utilize environmental factors to stimulate desired consumer behaviors. Background music has been identified as one of the most readily manipulated and influential elements to which a shopper or consumer may be exposed to in a service setting. Nevertheless, little is known about the effect of background sound on food perception and acceptance. This research sought whether background music genre and musical components can alter food perception and acceptance, but also to determine how the effect can vary as a function of food type (i.e., emotional vs. non-emotional) and source of music editor (i.e., single vs. multiple). In Experiment 1, single and multiple editors transposed the traditional music piece, Air on the G String, into four genres: classical, rock, hip-hop, and jazz. The same music piece was edited into contrasting ends of musical components of tempo, pitch, and volume for Experiment 2. According to a preliminary survey centering on the association between food and emotion, milk chocolate (emotional), and bell pepper (non-emotional) were selected as food stimuli for both experiments. Following consumption, participants rated flavor intensity, flavor pleasantness, texture liking, and overall liking using 15-cm line scales. In Experiment 1, participants liked food stimuli significantly more with the jazz stimulus as opposed to the hip-hop stimulus. Ratings of flavor pleasantness and overall impression for food stimuli only differed between the single editor genres. In Experiment 2, participants liked bell pepper flavor and texture significantly more with the fast tempo versus the slow tempo stimulus. Ratings of chocolate texture and bell pepper overall impression significantly heightened in the low pitch condition. In the loud volume condition, participants\u27 evaluated flavor pleasantness, texture impression, and overall impression of chocolate significantly higher in comparison to the quiet and silent conditions. In summary, the present thesis presents new empirical evidence that music genre, components, and editor, along with food type can modulate food perception and acceptance. Furthermore, our findings assist food service industries in creating the most appropriate atmosphere by explaining observed consumer behaviors induced by musical stimuli

The effect of non-leading foot placement on power in the fencing lunge.

Fencing success does not depend on specific morphological or physiological attributes. Nevertheless, the muscular demands are very specific and development of effective movement takes time and practice. Being able to lunge appropriately and with adequate power is an essential ability for fencers. But while the pattern of muscular activation is known, the effect of foot placement has not been investigated. Using a TENDO weightlifting analyzer to assess velocity and power, the impact of foot placement angle on lunge power is studied

Changes of smooth muscle contractile filaments in small bowel atresia

AIM: To investigate morphological changes of intestinal smooth muscle contractile fibres in small bowel atresia patients. METHODS: Resected small bowel specimens from small bowel atresia patients (n = 12) were divided into three sections (proximal, atretic and distal). Standard histology hematoxylin-eosin staining and enzyme immunohistochemistry was performed to visualize smooth muscle contractile markers α-smooth muscle actin (SMA) and desmin using conventional paraffin sections of the proximal and distal bowel. Small bowel from age-matched patients (n = 2) undergoing Meckel's diverticulum resection served as controls. RESULTS: The smooth muscle coat in the proximal bowel of small bowel atresia patients was thickened compared with control tissue, but the distal bowel was unchanged. Expression of smooth muscle contractile fibres SMA and desmin within the proximal bowel was slightly reduced compared with the distal bowel and control tissue. There were no major differences in the architecture of the smooth muscle within the proximal bowel and the distal bowel. The proximal and distal bowel in small bowel atresia patients revealed only minimal differences regarding smooth muscle morphology and the presence of smooth muscle contractile filament markers. CONCLUSION: Changes in smooth muscle contractile filaments do not appear to play a major role in postoperative motility disorders in small bowel atresia

Saving the black Catholic experience of Xavier University of Louisiana

The digital conversion and creation of accessible records from the Sisters of the Blessed Sacrament (SBS) Oral History Collection includes recorded and transcribed interviews with the Sisters of the Blessed Sacrament who, in 1915, founded Xavier University of Louisiana (XULA) and continue to serve today. This article reflects on the beginnings of XULA and its unique place in Southern black history as the only Roman Catholic historically black college or university (HBCU) in the United States. It examines the necessity of archival oral history preservation at an African-American institution of higher education and the work archivists at Xavier University of Louisiana are doing now to help conserve rare primary research materials for the long-term preservation of black Catholic history

Measurement of Vibration and Noise During the Installation of Rammed Aggregate Piers

The objective of the study was to record and evaluate ground vibration and noise generated during the installation of rammed aggregate piers (RAPs). Summarized are ground vibration and noise induced by the ramming equipment (i.e. the hydraulic break hammer and rammer) during the installation of forty-five RAPs at a single site. Data were collected during the entire installation process for each pier, which allowed for the measurement of ground vibration and noise levels for periods when the ramming equipment was positioned at different depths within the RAP. Measurements were also taken at different horizontal distances from the ramming equipment and RAP being installed. The entire data set consists of over 160 ground vibration measurements and over 260 noise measurements. Peak ground velocities measured during the study ranged between approximately 0.5 and 15 millimeters per second for horizontal distances ranging between 1.5 and 10.5 meters. Corresponding vibration frequencies ranged between approximately 20 and 60 Hz. Measured noise levels ranged between approximately 82 and 111 dBA for measurement locations between approximately 1.5 and 10.5 meters from the hammer. Overall, these measured ground vibrations and noise levels are moderate in nature and below those typically generated during pile driving

Teaching consolidation: Case study of preloading with vertical drains

This paper describes a ground improvement case study where preloading and prefabricated vertical drains (PVDs) were used to accelerate foundation settlements. The case study is used in a classroom setting with the learning objective of introducing engineering students to methods for estimating settlement of shallow foundations on compressible soils. The project site was developed for a corporate retail chain planning to open a new facility in San Luis Obispo, California. Up to 2.5 meters of fill were needed across much of the site to raise foundations and improvements above the flood elevation. Loads from the fill and the structure were expected to cause total and differential settlements that exceeded the allowable values established by the retailer. To mitigate settlement, the geotechnical engineer developed a preloading plan. Although the soil conditions were complex (e.g., interlayering, dipping strata, variable compressibility), the preloading plan was successful in achieving the desired settlement within 3 months, and subsequent site performance has been exemplary. This case study has been used for several years within a quarter-long shallow foundation design course to teach settlement performance. Learning outcomes from the assignment are summarized in the paper. Students are given the subsurface information and test results originally acquired by the geotechnical engineer. The students, working in teams, try to estimate how much primary consolidation settlement will occur due to the fill plus the preload, and the PVD spacing needed to achieve 90% of that settlement in 3 months. The assignment and relevant data are included herein along with the grading policy. The project culminates with the geotechnical engineer of record presenting in class the results of site monitoring during preloading and consolidation. These results include settlements across the 16,908 m2 site, which were tracked up to three times a week at 20 locations. This project affords students a case study experience that is rich in the “messy” details of a complex and local (i.e. familiar) geotechnical project. Included is a discussion of lessons learned by the instructors who have taught several iterations of this case study
