rationally pay to settle the obligation at the end of the reporting period or to transfer it to a third party at that time. Risks and uncertainties are taken into account in the measurement of a provision. A provision is discounted to its present value. FRS 37 elaborates on the application of the recognition and measurement requirements for three specific cases: • Future operating losses – A provision cannot be recognised because there is no obligation at the end of the reporting period.

insurance companies. Around 51% of its business was in Germany with a 60% of its business in the field of retail insurance. Its keys to success were the traditional insurance management and its remarkable customer service. In DA‚ a typical process flow of a new policy would start by either a customer going to one of the companies branches or contacting a company agent. The customer would fill out an application – sometimes a check was attached- and the application was then sent through the company

1. Identify the type of the following circuits as either serial or parallel. 2. List four characteristics of a series circuit. 1) The total current is the same everywhere in the circuit. 2) A series circuit only has one path for current to flow. 3) The sum of all the voltages sources is equal to the sum of all the voltage drops. 4) The total resistance in the circuit is equal to the sum of the individual resistances. 3. Calculate the total resistance in the circuit below. Show the formula

An investigation of how and why channel characteristics vary across the River Caerfarell‚ in Brecon Beacons National Park. Introduction: In my report‚ I will investigate how well the Bradshaw model fits in river Caerfanell. In particular my report will focus on 3 sub questions; 1. How does the cross-sectional area of the river Caerfanell change with distance downstream? 2. How does the velocity change with distance downstream? 3. How does channel efficiency change with distance downstream

conditions for the day was fair with a few citrus clouds and strong winds. Three (3) sites were selected to be observed in the lower and middle course of the Swift River. At each site the depositional land form were analysed and identified. Multiple measurements were made and recorded. The three (3) sites that were studied can be identified on a map (topographical sheet‚ scale 1:50) and their sizes were determined using one scale of the map and also information recorded at the site.

shown in Figure A. Two separate adjustable supplies (VGG and VDD) were used for the experiment. The grounds for both supplies were connected to the circuit ground. 2) The VDD was adjusted to 24V A. With VDD = 24V‚ VGG was adjusted to 0V. i) Measurements. Answers were recorded in Table 1 The Gate-Source voltage (VGS) and Drain-Source (VDS) were measured and recorded. ii) Calculations.

change due to the length of wire. The length of wire will be measured accurately using a metre rule. The wire will be stuck onto the rule using tape. This means that the wire will not move about so we can measure the length accurately. Repeating measurements improve accuracy as you can spot any anomalies and the results can be averaged to give more reliable results. The voltmeter will give the reading for voltage ( V ) and the ammeter will give the reading for current ( I ). The resistance will then
