Sprue cutoff tool for molded FCC plugs
Sprue removal operation is accomplished by positioning plug on tool bed, adjusting blades, and moving handle down for cutting process. Blades are raised to remove trimmed plug
Economic Growth and Threatened and Endangered Species Listings: A VAR Analysis
We conduct several analyses to examine the link between threatened and endangered species listings and macroeconomic activity. Preliminary tests using ordinary least squares are run on both time series data on the national level and cross sectional data at the state level. The analysis is then extended using vector autoregressive (VAR) techniques. VAR results, impulse response functions and variance decompositions are reported to shed more light on the causal relationships between threatened and endangered species, GDP and population. Our results indicate that there is little or no empirical evidence that GDP growth rates lead to changes in the number of threatened and endangered species listings.

Training healthcare assistants working in adult acute inpatient wards in Psychological First Aid: An implementation and evaluation study.
WHAT IS KNOWN ON THE SUBJECT: Healthcare assistants are untrained and unregistered frontline staff but are expected to be proactive in preventing and responding to 'untoward' incidents quickly and efficiently when working within adult acute inpatient psychiatric settings. Healthcare assistants should be trained to provide enhanced care to service users residing in acute psychiatric settings. To date, a training programme in Psychological First Aid has not been expended in such a setting with nonregistered staff. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: The study demonstrates that training healthcare assistants in Psychological First Aid is useful in improving their confidence in caring for service users, therapeutic engagement with service users and ward culture in general. WHAT ARE THE IMPLICATIONS FOR PRACTICE: A training programme in Psychological First Aid for healthcare assistants to enhance ward culture can be implemented in different practice environments. Psychological First Aid is harmonious with nursing values and provides healthcare assistants with a relevant, useful and easily understood toolkit to apply in acute psychiatric settings. ABSTRACT: Introduction Healthcare assistants working within adult acute inpatient psychiatric settings are untrained and unregistered, however, they can contribute to quality service if they receive some training. Psychological First Aid training has never been expended in these settings, so this study intends to fill this gap in the existing evidence with this category of healthcare personnel. Aim The aim of this study was to introduce and evaluate first aid training for healthcare assistants. Method A pre/post design was adopted to gather data using questionnaires and interviews. The groups of participants included 16 healthcare assistants trained in Psychological First Aid, a sample of service users and four ward managers. Results Post-training, (a) healthcare assistants and service users ranked the therapeutic milieu of the ward more favourably, (b) the self-efficacy of the healthcare assistants increased, and the number of 'untoward' incidents decreased, and (c) health care assistants' confidence in their skills was high. The ward manager interviews post-training revealed four themes: (a) staff utilization of new skills and renewed enthusiasm, (b) calmer atmosphere on the ward and staff togetherness, (c) confidence and reflection on practice and (d) therapeutic engagement. Discussion Training healthcare assistants is useful in improving staff confidence, therapeutic engagement with service users and ward culture in general. Implications for practice Techniques and skills learnt are relevant and useful to healthcare assistants and provide an easily understood toolkit that is harmonious with nursing values. If executed correctly, the training can enhance practice and care outcomes and the overall service user experience
A Simplified Mathematical Model for the Formation of Null Singularities Inside Black Holes I - Basic Formulation and a Conjecture
Einstein's equations are known to lead to the formation of black holes and
spacetime singularities. This appears to be a manifestation of the mathematical
phenomenon of finite-time blowup: a formation of singularities from regular
initial data. We present a simple hyperbolic system of two semi-linear
equations inspired by the Einstein equations. We explore a class of solutions
to this system which are analogous to static black-hole models. These solutions
exhibit a black-hole structure with a finite-time blowup on a characteristic
line mimicking the null inner horizon of spinning or charged black holes. We
conjecture that this behavior - namely black-hole formation with blow-up on a
characteristic line - is a generic feature of our semi-linear system. Our
simple system may provide insight into the formation of null singularities
inside spinning or charged black holes in the full system of Einstein
equations.Comment: 39 pages, 3 figures, extended versio
