Metals Production Requirements for Rapid Photovoltaics Deployment

If global photovoltaics (PV) deployment grows rapidly, the required input materials need to be supplied at an increasing rate. In this paper, we quantify the effect of PV deployment levels on the scale of metals production. For example, we find that if cadmium telluride {copper indium gallium diselenide} PV accounts for more than 3% {10%} of electricity generation by 2030, the required growth rates for the production of indium and tellurium would exceed historically-observed production growth rates for a large set of metals. In contrast, even if crystalline silicon PV supplies all electricity in 2030, the required silicon production growth rate would fall within the historical range. More generally, this paper highlights possible constraints to the rate of scaling up metals production for some PV technologies, and outlines an approach to assessing projected metals growth requirements against an ensemble of past growth rates from across the metals production sector. The framework developed in this paper may be useful for evaluating the scalability of a wide range of materials and devices, to inform technology development in the laboratory, as well as public and private research investment

Growth in metals production for rapid photovoltaics deployment

If global photovoltaics (PV) deployment grows rapidly, the required input materials need to be supplied at an increasing rate. We quantify the effect of PV deployment levels on the scale of annual metals production. If a thin-film PV technology accounts for 25% of electricity generation in 2030, the annual production of thin-film PV metals would need to grow at rates of 15-30% per year. These rates exceed those observed historically for a wide range of metals. In contrast, for the same level of crystalline silicon PV deployment, the required silicon production growth rate falls within the historical range.United States. Dept. of Energy (Grant DE-EE0006131

Pressure and pain In Systemic sclerosis/Scleroderma - an evaluation of a simple intervention (PISCES): randomised controlled trial protocol

Background: foot problems associated with Systemic Sclerosis (SSc)/Scleroderma have been reported to be both common and disabling. There are only limited data describing specifically, the mechanical changes occurring in the foot in SSc. A pilot project conducted in preparation for this trial confirmed the previous reports of foot related impairment and reduced foot function in people with SSc and demonstrated a link to mechanical etiologies. To-date there have been no formal studies of interventions directed at the foot problems experienced by people with Systemic Sclerosis. The primary aim of this trial is to evaluate whether foot pain and foot-related health status in people with Systemic Sclerosis can be improved through the provision of a simple pressure-relieving insole. Methods: the proposed trial is a pragmatic, multicenter, randomised controlled clinical trial following a completed pilot study. In four participating centres, 140 consenting patients with SSc and plantar foot pain will be randomised to receive either a commercially available pressure relieving and thermally insulating insole, or a sham insole with no cushioning or thermal properties. The primary end point is a reduction in pain measured using the Foot Function Index Pain subscale, 12 weeks after the start of intervention. Participants will complete the primary outcome measure (Foot Function Index pain sub-scale) prior to randomisation and at 12 weeks post randomisation. Secondary outcomes include participant reported pain and disability as derived from the Manchester Foot Pain and Disability Questionnaire and plantar pressures with and without the insoles in situ. Discussion: this trial protocol proposes a rigorous and potentially significant evaluation of a simple and readily provided therapeutic approach which, if effective, could be of a great benefit for this group of patients

Agreement between the Physiotherapists and Mothers

[Purpose] The aim of this study was to examine the agreement between physiotherapists (PTs) and mothers (Ms) about the treatment of children with cerebral palsy (CP) who received treatment in special education and rehabilitation centers. [Subjects] Ms of 130 children with CP (75 boys, 55 girls) and 130 PTs who applied rehabilitation programs were interviewed. [Methods] Clinical types and gross motor function levels of the children were recorded. A questionnaire consisting of 6 open-ended questions was used to describe the expectations and views of the PTs and Ms about the physiotherapy and rehabilitation programs for the children. [Results] The mean age of the children was 89.80 +/- 52.05 months. The mean treatment period for the children was 73.62 +/- 42.11 months. The mean age of the mothers was 35.47 +/- 5.79 years, and the mean age of the PTs was 28.07 +/- 7.28 years. We found a statistically moderate level of agreement between the PTs and Ms regarding the appropriateness of the treatment provided to the children. There was statistically insignificant agreement regarding the applied treatment methods and the appropriateness of the applied rehabilitation programs. [Conclusion] We believe that the views and expectations of the Ms should be taken into account by the PTs when preparing a treatment program for children with CP

BACKGROUND AND OBJECTIVE: The aim of this study is to examine the relationship between quality of life, activity-participation and environmental factors in adolescents with cerebral palsy. METHODS: Seventy-five adolescents (M:45, F:30) ages between 14-18 yrs (mean: 15.52±1.60 yrs) were included in the study. Participants were divided into three groups: Level I, Level II and Level III according to the Gross Motor Function Classification System. Gross Motor Function Classification System, Gross Motor Function Measure, Functional Independence Scale, Manuel Ability Classification System, Pediatric Quality of Life Inventory and International Classification of Functioning, Disability and Health Child-Youth version Short Form (ICF-CY) (14-18 yrs) were used for assessments. RESULTS: It is found that there is a moderate and high level of correlation between quality of life and activity participation and body functions; moderate and high level of correlation between quality of life and activity participation and body functions with the gross motor function levels; moderate and low level correlation between environmental factors and gross motor function levels (p < 0,05). CONCLUSIONS: The fact that the ICF-CY short form used for cerebral palsied children is compatible with other assessment scales suggests that the use of ICF-CY short forms may be useful in assessing the health status of individuals

Introducing Architectural Design Foundations Through Algorithmic Design and Experimentations with Materials: a methodology for freshman class in architecture

This paper presents a lecture methodology using pattern based and algorithmic design principles for an introductory architectural design course aimed towards students who are not oriented in design practices but in natural sciences. This methodology is built upon eights interconnected steps, starting with analytical pattern extraction from nature - from the unique texture and structure of a plant (seed or fruit) and also from its lifecycle and relation to the existing habitat. The steps include abstract pattern making with the use of software tools and material building of abstracted geometries as standalone structures. Throughout these steps, principles of information design field is demonstrated to improve students abilities to analyze visual information
