A Raman spectroscopic study of carbon phases in impact melt rocks and breccias from the Gardnos impact structure, Norway
Raman spectroscopy suggests that the C was emplaced in at least two separate episodes into the impactites of the Gardnos impact structure
Increasing wheat yields through breeding
With the current \u27cost price\u27 sueeze facing Australia\u27s farmers, the development of new higher yielding varieties is moe important that ever. By growing higher yielding varieties, farmers can increase their returns at virtuakky no additional cost: for example a wheat variety that produces 5 per cent extra yield from 1 t/ha crop returns about an additional $8/ha. Farmers can therefore increase their production by growing improved varieties

De l’idéologie de l’espace à l’idéologie dans l’espace
Plutôt que d'étudier les dimensions idéologiques du discours des géographes, cet article s'interroge sur la pertinence et les méthodes possibles d'une lecture de l'inscription de la dimension idéologique d'une société dans l'espace que celle-ci a produit. Rappelant l'importance d'une réflexion géographique sur les caractéristiques spatiales liées à l'idéologie d'une formation sociale, les auteurs s'appuient sur les études ayant pour but de mesurer la qualité de la vie, telle que perçue par les habitants, ainsi que sur celles portant sur la perception et l'économie politique du risque nucléaire pour reconnaître l'intérêt et la possibilité, sous certaines conditions, d'une étude scientifique des faits idéologiques, tels qu'en dernière analyse ils se lisent dans l'espace géographique lui-même.Rather than studying the ideological dimension of geographical discourse, this article addresses the question of the relevance and possible methodology for analyzing ideological dimensions, within the space created by a given society. Recalling the importance of a geographical approach to spatial characteristics linked to the ideologies of social formations, the authors base their work on studies whose aim is to measure the quality of life, as perceived by the population, as well as those dealing with the awareness and political economy of nuclear risks, to define the relevance and feasibility, under certain circumstances, of the scientific study of ideological phenomena, such as can be ascertained, in the final analysis, from a given geographical space

Barr-Klarman Arts Capacity Building Initiative Financial Health Evaluation Summary
This document provides an overview of a financial health evaluation TDC conducted in 2017 to capture the financial health trends of a Boston-based cohort of arts organizations who participated in the Barr-Klarman Arts Capacity Building Initiative (2012-2017), a joint grant program of the Barr Foundation and The Klarman Family Foundation. TDC's financial health evaluation was designed to impart a clear financial picture of the cohort at the program's end, as well as complement the qualitative evaluation of the Initiative (2016-2017) led by Diane Espaldon and Sara Peterson.The financial health evaluation measured the growth and scale of grantees' operations over the course of the Initiative; assessed cumulative financial health; and observed capitalization literacy. TDC evaluators provided each grantee with a capitalization assessment reflecting their organization's balance sheet and income statement trends over the course of the program. Grantees subsequently participated in a follow-up phone interview with TDC to discuss their financial results, and answer questions regarding the impact of the Initiative's capitalization training program on their strategic decision-making and financial goal-setting. With a sample of 30 organizations, TDC evaluated grantee financial performance in the context of each organization's individual goals, not against a cohort-wide benchmark. Cohort-wide trends were elicited from an aggregation of individual performance.This summary document provides an overview of the Initiative's capitalization program, the capitalization framework TDC employed, and high-level results from the financial health evaluation

A Comparison of Rainfall Estimation Techniques
This study compares two techniques that have been developed for rainfall and streamflow estimation with the aim of identifying strengths and weaknesses of each. The first technique utilises thin plate smoothing splines to develop rainfall surfaces for the catchment, which are then, in conjunction with daily point-wise rainfall data used to determine areal catchment estimates. The second technique develops a regression-based model relating elevation to total annual rainfall in order to scale rainfall for daily mean catchment rainfall estimates. Both approaches are compared in common catchments in the upper Murrumbidgee catchment. The comparison includes using the data from each of the approaches as input to a rainfall-runoff model and by comparison of the quality of modelled results to observed streamflow. The strengths, weaknesses and use for catchment managers in decision making are identified. The study results revealed that where rain station spatial density and data quality are high, both regression and the spline method perform equally as well in estimating long term rainfall trends. In conclusion, catchment managers could apply the simple regression technique over the sophisticated spline method to achieve the comparable results. This is particularly useful where an efficient yet simple method is required for assessing streamflow within similar catchments
