Results of an Interlaboratory Study of the ASTM Standard Test Method for Tensile Properties of Polymer Matrix Composites D 3039

An investigation was conducted on the ASTM Standard Test Method for Tensile Properties of Polymer Matrix Composites (D 3039). This investigation consisted of both preliminary testing and an interlaboratory test program. Information generated from preliminary testing was used to determine the effects of various parameters and to optimize the interlaboratory test plan and test protocol. The interlaboratory study portion of this investigation was conducted on six composite material systems in a variety of lay-up configurations. The number of participating labs ranged from five to nine depending on the material type. Precision statistics were determined for the ASTM D 3039 standard from the data generated by the interlaboratory testing in accordance with the ASTM Standard Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test Method (E 691)

Thrust chamber life prediction. Volume 1: Mechanical and physical properties of high performance rocket nozzle materials

Pertinent mechanical and physical properties of six high conductivity metals were determined. The metals included Amzirc, NARloy Z, oxygen free pure copper, electroformed copper, fine silver, and electroformed nickel. Selection of these materials was based on their possible use in high performance reusable rocket nozzles. The typical room temperature properties determined for each material included tensile ultimate strength, tensile yield strength, elongation, reduction of area, modulus of elasticity, Poisson's ratio, density, specific heat, thermal conductivity, and coefficient of thermal expansion. Typical static tensile stress-strain curves, cyclic stress-strain curves, and low-cycle fatigue life curves are shown. Properties versus temperature are presented in graphical form for temperatures from 27.6K (-410 F) to 810.9K (1000 F)

Digital art in designing an artistic image

The research aim lies in describing new approaches in art. The use of digital art allows displaying an artistic image that perceives new ideals. The development of digital art in the era of global digitization implies introducing several modern tools for designing an artistic image. The paper raises the issue of the media of digital works, including photographic paper and canvas. The technological and automated side of some or all digital works is also described. The question of their uniqueness or singularity is raised. The paper reveals the aesthetic aspect of a computer-designed work, which depends primarily on the parameters of brightness, contrast, and saturation of the creative software used, as well as the parameters chosen for printing. Since this aspect is the same as for a traditional work reproduced in printed form, from a purely artistic point of view, a digital work can resemble a traditional work in every way if it borrows elements from it, such as hand-painted or digitally drawn textures. Moreover, when traditional techniques are combined with digital techniques, creative ways are likely to multiply because of the variety of techniques. Consideration is given to the use of correction tools to facilitate modification of the composition

The Perceived Care Needs of Breast Cancer Patients in Korea

By analyzing the data of 459 patients who completed the Supportive Care Needs Survey (SCNS), the prevalence, medical and non-medical predictors of unmet needs were investigated. Breast cancer patients in Korea experienced high levels of unmet needs across the needs domains, particularly in the health system and information domain (56.9%). Various medical and non-medical variables were identified as significant predictors of unmet needs in each domain. By multivariate analyses, several predictors were identified across the domains including; less education (≤ 9 years) in the psychologic, chemotherapy, short post-surgical interval, and less education in the physical and daily living, younger age (< 50 years) in the sexuality, larger tumor size (> 2 cm) and younger age in the health system and information, and more education (≥ 13 years) in the care and support domain. The results of this study suggest medical professional should consider the complexity and dynamics of meeting patients' needs in providing supportive care services

Advancing Administrative Supports for Research Development

Research intensive universities have raised the bar for all academic units, expecting them to increase research grants and contracts to support knowledge creation and scholarship. Similarly, performance requirements for faculty have changed, with annual reviews and tenure and promotion decisions weighting obtaining grants along with publication of scholarly products, teaching effectiveness, and service to the school, university and community. These expectations compel Deans and Directors of schools of social work to undertake new roles related to research development and administrative capacity building in order to help faculty and their units succeed. Social work schools and departments must stay or become strategically positioned in their university or college, even as the context for research development has been dramatically altered as colleges and universities invest in the nanosciences or bio- technology rather than the social sciences. A $4 billion nanoscience operation dwarfs the$20 million that a robust research enterprise that a few schools of social work enjoy. This paper highlights some of the opportunities, barriers, challenges, as well as stepping stones to success in the process of building research supports and infrastructures. Drawing upon presentations at recent meetings of the National Association of Deans and Directors of Schools of Social Work (NADD) that have been organized by the Institute of Social Work Research (IASWR), we feature several examples of approaches advancing supports for research development. Brief scenarios illustrating efforts underway at several schools depict challenging and often rewarding research capacity building endeavors. This paper presents the perspective of several Deans and Directors in the development of administrative research supports. The paper also features one model for a supportive research administration structure in the pre- and post-award environment

High levels of untreated distress and fatigue in cancer patients

The purpose of the study was to assess a large representative sample of cancer patients on distress levels, common psychosocial problems, and awareness and use of psychosocial support services. A total of 3095 patients were assessed over a 4-week period with the Brief Symptom Inventory-18 (BSI-18), a common problems checklist, and on awareness and use of psychosocial resources. Full data was available on 2776 patients. On average, patients were 60 years old, Caucasian (78.3%), and middle class. Approximately, half were attending for follow-up care. Types of cancer varied, with the largest groups being breast (23.5%), prostate (16.9%), colorectal (7.5%), and lung (5.8%) cancer patients. Overall, 37.8% of all patients met criteria for general distress in the clinical range. A higher proportion of men met case criteria for somatisation, and more women for depression. There were no gender differences in anxiety or overall distress severity. Minority patients were more likely to be distressed, as were those with lower income, cancers other than prostate, and those currently on active treatment. Lung, pancreatic, head and neck, Hodgkin's disease, and brain cancer patients were the most distressed. Almost half of all patients who met distress criteria had not sought professional psychosocial support nor did they intend to in the future. In conclusion, distress is very common in cancer patients across diagnoses and across the disease trajectory. Many patients who report high levels of distress are not taking advantage of available supportive resources. Barriers to such use, and factors predicting distress and use of psychosocial care, require further exploration

The third Symptom Management Research Trial in Oncology (SMaRT Oncology-3): a randomised trial to determine the efficacy of adding a complex intervention for major depressive disorder (Depression Care for People with Lung Cancer) to usual care, compared to usual care alone in patients with lung cancer

Background: Depression Care for People with Lung Cancer is a complex intervention delivered by specially trained cancer nurses, under the supervision of a psychiatrist. It is given as a supplement to the usual care for depression, which patients receive from their general practitioner and cancer service. The third Symptom Management Research Trial in Oncology (SMaRT Oncology-3 Trial) will test its efficacy when compared to usual care alone. Design: A two arm parallel group multi-centre randomised controlled trial. 200 patients will be recruited through established systematic Symptom Monitoring Services, which screen patients for depression. Patients will have: a diagnosis of lung cancer; an estimated life expectancy of three months or more and a diagnosis of Major Depressive Disorder. Patients will be randomised to usual care or usual care plus Depression Care for People with Lung Cancer. Randomisation will be carried out by telephoning a secure computerised central randomisation system or by using a secure web interface. The primary outcome measure is average depression severity. This will be assessed using scores on the 20-item Symptom Hopkins Checklist (SCL-20D), collected every four weeks over 32 weeks. Secondary outcomes include severity of anxiety, pain and fatigue; self-rated improvement of depression; quality of life and satisfaction with depression care

Preferences for long-term follow-up care in childhood cancer survivors

Follow-up care is important for childhood cancer survivors to facilitate early detection and treatment of late effects. We aimed to describe preferences for different organisational aspects and models of follow-up care among Swiss childhood cancer survivors, and characteristics associated with preferences for different models. We contacted 720 survivors aged 18+ years, diagnosed with cancer after 1990 (age 0-16 years), registered in the Swiss Childhood Cancer Registry (SCCR), and Swiss resident, who previously participated in a baseline survey. They received questionnaires to assess attendance and preferences for follow-up (rated on 4-point scales, 0-3). Clinical information was available from the SCCR. Survivors (n = 314: response rate 43.6%; 47.8% still attended follow-up) rated clinical reasons for follow-up higher than supportive reasons (p < .001). They rated checking for cancer recurrence (mean = 2.78, SD = 0.53) and knowing about risks for my children most important (mean = 2.22, SD = 0.83). They preferred to attend a children's hospital (mean = 1.94, SD = 1.11), adult hospital (mean = 1.86, SD = 0.98) or general practitioner (mean = 1.86, SD = 1.01) rather than a central specialised late effects clinic (mean = 1.25, SD = 1.06, p < .001), and be seen by paediatric (mean = 2.24, SD = 0.72) or medical oncologist (mean = 2.17, SD = 0.69). Survivors preferred decentralised clinic-based follow-up, rather than one central specialised late effects clinic. Survivors' preferences should be considered to ensure future attendance

The long-term impact of cancer: Evaluating psychological distress in adolescent and young adult cancer survivors in Switzerland

Objectives Adolescents and young adults (AYAs) are diagnosed with cancer during a critical life period full of psychosocial challenges. They may experience a significant impact of the cancer diagnosis on their psychological health, also in the long term. We aimed to (a) evaluate psychological distress in AYA cancer survivors and compare levels of distress with controls and (b) describe socio‐demographic and cancer‐related characteristics associated with psychological distress. Methods We sent a questionnaire to AYA cancer survivors (aged 16‐25 y at diagnosis, survived ≥5 y) registered in the Cancer Registry Zurich and Zug, Switzerland. Psychological distress was measured using the Brief Symptom Inventory‐18 (BSI‐18) assessing anxiety, depression, and somatization and a global severity index (GSI) (cutoff score indicating psychological distress: T ≥ 57). Distress levels were compared between survivors and controls. We used logistic regression to determine associations of socio‐demographic and cancer‐related characteristics with distress. Results Of 160 AYA cancer survivors, 34 (21%) reported being distressed (27% in women, 17% in men; P = 0.129). Compared with controls, survivors did not report higher levels of distress (all P values > 0.05). Survivors with migration background and survivors with late effects reported higher levels on GSI, somatization, and anxiety. Higher levels of depression were associated with being female, not being in a partnership, and having late effects. Conclusions A substantial subgroup of AYA cancer survivors reported psychological distress. Systematically screening for distress and providing psychological follow‐up for survivors at risk may help to provide adequate psychological support
