Causes Of Dull Brown Color In Durum And Traditional Semolina Pasta, Patricia Alejandra Cabas Lühmann

Plant Sciences

Bleaching of durum wheat (Triticum turgidum L. ssp. durum [Desf.] Husn.) was evaluated by determining the effect of grain moisture content, temperature, and wet/dry cycles with bulk water and with high relative humidity on the hydration of durum wheat grain and their effect on some physical grain quality parameters. Low initial grain moisture, high temperature, and wet/dry cycles increased water gain. Scanning electron microscopy and light microscopy showed that the germ and ventral surface of grain were important for water absorption. A single exposure to moisture (bulk water or high relative humidity) seems to be enough to cause a decline …

Screening For Forage Sorghum Genotypes With Chilling Tolerance, Swarup Podder

Plant Sciences

Forage sorghum (FS) [Sorghum bicolor (L.) Moench] is a warm-season biomass crop with the potential to become a bioenergy feedstock. The objective of this study was to screen potential FS genotypes for increased chilling tolerance and biomass productivity. The experiments were conducted in Fargo and Hickson, ND, in 2017 and 2018. Seventy-two genotypes of FS were tested at 24, 12, and 10℃. The genotypes were ranked from high to low vigor index and 12 genotypes were planted on two seeding dates: early (10 May) and late (27 May). Field emergence index values were greater for the late-seeding compared with the …

Using Organic Amendments To Stabilize Sand-Based Athletic Fields During Turfgrass Establishment Period, Thomas Drietz

Plant Sciences

Athletic field rootzones are often sand-based for improved drainage. Sand-based rootzones may have stability issues if turfgrass is not fully established. Our objective was to use organic amendments to improve the stability of sand-based fields during the turfgrass establishment period and avoid overuse of inorganic materials, which have negative effects. We tested coconut coir, peat and wheat straw at 1% organic material, peat at 2% organic material, and an inorganic stabilizing fiber, StaLok, in the top 10 cm of the rootzone. Surface hardness, volumetric water content, traction, penetration resistance and visual quality were measured 2 to 4 months after construction …

Implementation Of Screening And Outcome Measures At A Cancer Specific Mental Health Clinic, Hannah Katz

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

There is limited research examining the overall distress levels of cancer patients and caregivers longitudinally, as well as how to best implement distress surveys into a general community clinic. This study had two aims: (1) To implement surveys in a community-based clinic that serves cancer patients and their family members; and (2) To gain an understanding of the outcome of psychotherapy. The study included 15 participants—eight patients and seven student therapists—over a five-month period in the Center for Oncology Psychology clinic. Patients and therapists were matched in dyads. Surveys were provided to patients at three time points. Additionally, an outcome …

Pre-Harvest Glyphosate Effects On Properties Of Beta-Glucan From Oat Groats, Abdulrahman Alahmed

Plant Sciences

Pre-harvest glyphosate is applied to cereal grains to remove weeds. However, it has been claimed that oat compositions are affected by pre-harvest glyphosate. Research was conducted to evaluate differences in properties of β-glucan in the treated versus untreated oat groats. Two oat cultivars (Rockford and Souris) were grown at Minot and Prosper, North Dakota in 2015, and glyphosate was sprayed during the soft dough stage, physiological maturity stage, or not applied. β-Glucan viscosity was not significantly (p > 0:05) affected by treatment at soft dough or physiological maturity stages. Use of glyphosate at the soft dough stage significantly (p < 0:05) reduced the percentages of β-glucan content and solubility versus untreated samples. Treatment at soft dough and physiological maturity stages significantly (p < 0:05) increased β-glucan molecular weights compared to untreated controls. Therefore, glyphosate can be applied at the physiologically mature stage of grain development because β glucan properties from the groats were not negatively affected.

Flavor Modification Of Pea Flour Using Ethanol-Based Deodorization, Madison Taylor Gohl

Plant Sciences

Peas are rich in protein and dietary fiber and can be used to create specialty products; however, flavor issues are one of the primary concerns regarding utilization. Sensory evaluations indicated the optimal treatment utilized aqueous ethanol at a concentration of 47.5%, extraction time of 63 min, and no pressure. Decreased (P<0.05) moisture and ash content, with no loss of protein or starch, were observed after treatment. Foaming properties were poor, indicating protein modification. Increased water absorption impacted WAI, WSI, setback, and peak time observations. Remaining pasting profile values were unchanged (P<0.05). While some volatiles were released via changes in protein and starch structure, total ppm decreased. Treated pea flour products had significantly (P<0.05) higher flavor acceptance scores. Texture results suggested treated flour imparted softness of baked items. Shelf-life measurements were improved for both cookies and crackers using treated pea flour.

Temporal Trends In The Grip Strength Of Children And Adolescents, Faith Lavoy Dooley

Theses and Dissertations

Objective: To estimate national and international temporal trends in the handgrip strength of children and adolescents, and to examine relationships between trends in handgrip strength and trends in health-related and sociodemographic indicators.

Methods: Data were obtained in two ways: (a) through a systematic electronic database search for studies reporting on temporal trends in the handgrip strength of apparently healthy 9–17-year-olds, (b) pearling reference lists, topical systematic reviews and personal libraries, and (c) by examining large national fitness datasets suitable to temporal trends analysis. Sample-weighted temporal trends were estimated using best-fitting regression models relating the year of testing to mean handgrip …

Temporal Trends In The Standing Broad Jump Test Performance Of United States Children And Adolescents, Bridget Kate Pinoniemi

Theses and Dissertations

Muscular fitness is a very important indicator of health. Using a systematic review strategy, the aim of this study was to estimate the temporal trends in broad jump performance of United States youth. Broad jump data on apparently healthy United States youth (aged 10–17 years) were located through a systematic electronic database search and by pearling reference lists, topical systematic reviews and personal libraries. Sample-weighted temporal trends (expressed as percent and standardized trends) were estimated for separate age-sex groups using best-fitting regression models relating the year of testing to mean jump performance. Mean trends standardized to the year 1985 were …

Paleoecology Of Northern Great Plains Bison: Inferences From Stable Isotopes And Dental Calculus, Gaimi Lynn Davies

Theses and Dissertations

The purpose of this study is to infer Northern Great Plains bison (Bison bison) paleoecology through the analysis of stable isotopes and dental calculus from bison skeletal remains. Bison used to roam in the millions throughout most of North America but today they are primarily kept in confined and isolated populations. Little is known about their ancestral ecology. The abundance of bison in the archeological record provides a unique opportunity to study their remains on a broad temporal and spatial scale. This research uses the archeological record of bison in North Dakota to study bison diet and environment from the …
