Lower-limb dynamics in two approaches of stair descent initiation: walk and stand
No full textThe purpose of this study was to study the effects of different stair descent strategy on peak joint moment and peak joint power in healthy young adults. Fourteen healthy young subjects (8 males and 6 females) performed the stair descent. Walk approach included the component of level walking and stair walking. Stand approach included the component of only stair walking. A three-step stairway with a walkway was used for the motion trials. Significant difference was found in hip abductor moments, knee extensor moment and knee eccentric power between the two approaches. No significant difference was found for any variable between the genders. Stair descent initiation with walk approach requires larger hip and knee dynamics than stand approach in both the genders in order to achieve a safe stair descent.Texas Woman's University, Dento
The experience of chronic sorrow in parents who have a child diagnosed with a significant disability: investigating chronic sorrow across parental life
Full text linkThe focus and purpose of the this qualitative study is to describe parental\ud
experiences across the life cycle following the diagnosis of significant disability in their\ud
child and the concept of Chronic Sorrow described by Olshansky (1962). The study also\ud
hoped to provide avenues of expanding the Family Life Cycle theory (Carter and\ud
McGoldrick, 1988), The Contextual Approach to Family Stress Theory (Boss, 2002) and\ud
Ambiguous Loss (Boss, 1999, 2006) to become more inclusive for families who have a\ud
child with significant disabilities. Discussion surrounding Family Systems Illness Model\ud
(Rolland, 1994) and Experiential Family Therapy (Whitaker, 1989) were also included to\ud
provide understanding regarding the adaptations made by families and the use of\ud
Experiential Family Therapy with this particular family system to promote continued\ud
growth across the life cycle. Purposeful and Snowball sampling methods were used to\ud
contact 10 families living in the North Texas. Participants were asked to engage in\ud
audiotaped face to face interviews with the primary researcher. Responses to the research\ud
question and central prompts were transcribed from the audiotaped interviews and\ud
entered into a Word document for the purpose of coding. The coded data was studied\ud
\ud
and nine primary themes were identified. These primary themes were: (1) reaction to the\ud
diagnosis, (2) barriers (medical and informational), (3) adjustment (spousal, family,\ud
siblings, extended family), (4) resiliency, (5) supports (extended family and community),\ud
(6) hope, (7) future, (8) chronic sorrow, (9) individual adjustment. These primary themes\ud
were then compared to those developed by Boss (1999, 2006) in her depiction of\ud
Ambiguous Loss. Adaptations to these themes were decided and were condensed into\ud
seven final themes: (1) The Initial Reaction of Chronic Sorrow to the Diagnosis, (2)\ud
Finding Meaning in an Overwhelming Situation, (3) Tempering Mastering of Parenting a\ud
Child with a Disability, (4) Normalizing the Ambivalence of Parenting, (5)Parents\ud
Restructure their Identity, (6) Discovering Hope in the Redefined Family, and (7)\ud
Ambivalence about the Future.\ud
This study discovered through the interviews with the parent participants that the\ud
experience of Chronic Sorrow began soon after receiving the diagnosis of significant\ud
disability for their child even though they did not have a term to describe the sense of loss\ud
being experienced. Parents in this study experienced multiple changes in their ideas\ud
regarding the diagnosis of disability, understanding the role of parenting and lifelong\ud
caregiver, involvement and connection of extended family and the decisions surrounding\ud
the future for the parent as an individual and for the child as they aged. Chronic Sorrow\ud
was found to be an experience that lasts across the life cycle, it is not a time bound\ud
concept, nor does it resemble a grieving process which has been associated with the loss\ud
of a loved one. Chronic Sorrow shares some similar components with Ambiguous Loss,\ud
and could be considered a Chronic Stressor as described in the Contextual Model of\ud
\ud
Family Stress Theory (Boss, 2006). The study also provided possible inclusive\ud
adaptations to the Family Life Cycle Theory (Carter and McGoldrick, 1988) to include the\ud
disability diagnoses into the theory of the life cycle as well as adding an addition\ud
component to the theory that includes the process of the launching the child back into the\ud
home after school servicers have ended.Ladd, LInda Dr.\ud

Charting a Green Path Ahead: Texas Woman’s University’s Journey to Sustainability
No full textThree years ago Texas Woman’s University took to heart the American Chemical Society’s goal to become completely sustainable within 150 years. Ever since then, we as a university have been working toward a more environmentally friendly, sustainable laboratory environment. This semester, more time is being devoted to this goal. We have successfully completed a semester of organic chemistry using numerous “green” experiments, begun integrating discussion topics and green chemistry curriculum into the organic chemistry laboratory, are working toward being recognized by the ACS as a green chemistry chapter, integrating microwave chemistry into different chemistry courses and faculty research, and formulating a path towards our ultimate goal—complete sustainability. Faculty and students are committed to this goal in an unprecedented manner. Our hope is to become an institution that other universities look to as a role model and leader of how to become sustainable and environmentally conscious, without sacrificing scientific education.SENCER Center for Innovation – Southwest (Denton, TX), The National Center for Science Education and Civic Engagement (Washington, DC) and the National Science Foundatio
Effects of Different Exercise Environments on Perceived Exercise Affect for an Adult with Cerebral Palsy
Full text linkPurpose: The purpose of this study was to examine the influence of different exercise environments (public vs non-public gym) on perceived exercise affect (feelings) for an adult with cerebral palsy (CP). Method: The Physical Activity Affect Scale (PAAS) was used once a week for seven weeks to assess the pre-post perceived exercise affect. Results: The results of this study indicated highly positive exercise affects in either environment . However, the increase of perceived exercise affect in the public gym setting was greater than non-public environment prior to exercising. Conclusion: Both environments impacted perceived exercise affect; the public exercise setting may have increased a greater positive influence. Additional research is needed to further determine the effects of exercise setting on exercise induced affect for persons with disabilities
SEPARATION AND ANALYSIS OF COTTONSEED OIL DEODORIZER DISTILLATE (CODD) USING MOLECULAR DISTILLATION
No full textA molecular distillation (MD) method was developed to separate the unsaponifiables from Cottonseed oil deodorizer distillate (CODD), which contains free fatty acids (FFA), mono/diglycerides, tocopherols and sterols. Using a model KDL6 MD glass still with a 0.06 m2 evaporator, five passes were conducted using different evaporator temperatures and with the condenser temperature held at 60°C and vacuum at 0.22 mmHg. With the feed rate of 0.2 kg/hr, at a temperature of 60°C, samples of the CODD were separated into the distillate and residue portion. Using a gas chromatography silylation method, quantification of the components was determined. The pass 4 distillate was composed of 90.8% of FFA and 4.3% of unsaponifiables and the residue had 63% unsaponifiables. Using this residue for stage-2, unsaponifiables were 84.5% of the distillate while the residue had 97.14% diglycerides. Molecular distillation is a solvent-free process, avoiding problems with toxicity. This laboratory method using a 2-stage process successfully distilled the unsaponifiables from the components of CODD and distilled the valuable tocopherols and sterols and the FFA.DocHale Food ingredient
Changing the Perception of Chemistry through Community Outreach: Inspiring Future Scientists
No full textThe Kappa Epsilon Mu (KEM) Club at Texas Woman's University (TWU) plays an integral part of our Denton campus and local community. As a student organization representing TWU, our goal is to inspire the next generation of scientists by presenting the fascinating aspects of chemistry through exciting visual demonstrations and other community activities. The TWU KEM club helps sponsor several special events on campus as well as taking our “KEM to U” show on the road to local elementary, middle and high schools. We have also started our “Calculate it Forward” campaign. This campaign allows students, faculty and community members to donate their unused calculators, so KEM club can then provide them to a community organization or school in need. Through our efforts we will continue to educate and inspire future scientists by sharing our knowledge and passion for chemistry with the students and community.American Chemical Society\ud
