Known Impacts of Tropical Cyclones, East Coast, 1858 – 2008 by Mr Jeff Callaghan Retired Senior Severe Weather Forecaster, Bureau of Meteorology, Brisbane
ARCHIVE: Known Impacts of Tropical Cyclones, East Coast, 1858 – 2008 By Mr Jeff Callaghan Retired Senior Severe Weather Forecaster, Bureau of Meteorology, Brisbane The date of the cyclone refers to the day of landfall or the day of the major impact if it is not a cyclone making landfall from the Coral Sea. The first number after the date is the Southern Oscillation Index (SOI) for that month followed by the three month running mean of the SOI centred on that month. This is followed by information on the equatorial eastern Pacific sea surface temperatures where: W means a warm episode i.e. sea surface temperature (SST) was above normal; C means a cool episode and Av means average SST Date Impact January 1858 From the Sydney Morning Herald 26/2/1866: an article featuring a cruise inside the Barrier Reef describes an expedition’s stay at Green Island near Cairns. “The wind throughout our stay was principally from the south-east, but in January we had two or three hard blows from the N to NW with rain; one gale uprooted some of the trees and wrung the heads off others. The sea also rose one night very high, nearly covering the island, leaving but a small spot of about twenty feet square free of water.” Middle to late Feb A tropical cyclone (TC) brought damaging winds and seas to region between Rockhampton and 1863 Hervey Bay. Houses unroofed in several centres with many trees blown down. Ketch driven onto rocks near Rockhampton. Severe erosion along shores of Hervey Bay with 10 metres lost to sea along a 32 km stretch of the coast. -

Durridge RAD H2O User Manual
RAD H2O Radon in Water Accessory for the RAD7 User Manual INTRODUCTION Te RAD H2O is an accessory to the RAD7 that enables you to measure radon in water over a concentration range of from less than 10 pCi/L to greater than 400,000 pCi/L. By diluting your sample, or by waiting for sample decay, you can extend the method's upper range to any concentration. Te equipment is portable and battery operated, and the measurement is fast. You can have an accurate reading of radon in water within an hour of taking the sample. Te RAD H2O gives results afer a 30 minutes analysis with a sensitivity that matches or exceeds that of liquid scintillation methods. Te method is simple and straightforward. Tere are no harmful chemicals to use. Once the procedure becomes familiar and well understood it will produce accurate results with minimal effort. It is assumed that the user has a good, working knowledge of the RAD7. If both the RAD7 and the RAD H2O are new to the user, then time should be spent learning how to make good measurements of radon in air with the RAD7 before embarking on radon in water measurements. Instructions for RAD7 operation with the RAD H2O are given in this manual but, for more detail about the instrument and its use, the reader is referred to the RAD7 manual. Grateful acknowledgment is made of the signifcant contribution to this manual by Stephen Shefsky, who wrote most of the original NITON RAD H2O manual, much of which is incorporated in this version. -
The Bottomless Bottle Explosion Properties of Hydrogen SCIENTIFIC
The Bottomless Bottle Explosion Properties of Hydrogen SCIENTIFIC Introduction Generate hydrogen gas using aluminum metal and sodium hydroxide and ignite. Something interesting will happen! When an empty, bottomless soda bottle is filled with hydrogen and the gas ignited, the hydrogen will burn with the flame decreasing in size. After awhile, the reaction will whistle. Suddenly, the hydrogen will explode with water vapor condensing on the inside surface of the bottle. Concepts • Hydrogen gas • Combustion • Stoichiometric ratio Materials Calcium chloride, anhydrous or Drierite® Ring stand and clamp Sodium hydroxide solution, NaOH, 5.5 M, 50 mL Rubber tubing, 3–4 ft, 3⁄16″ ID × 1⁄16″ wall Aluminum foil Stoppers, one-hole, to fit flask, bottle, and drying tube Bottle, water or soda, tall Tubing, 5–6 mm, 1½″ long piece Butane safety lighter Tubing, Pyrex® glass, 2″ long piece Cotton puff Volumetric flask, 500-mL Drying tube Safety Precautions This is not a demonstration for the inexperienced teacher. The production of the hydrogen is dangerous. Hydrogen is a very flammable and potentially explosive gas but can be safely handled with proper safety procedures. Never generate hydrogen in a closed system; always make sure there are no plugs or blockages in the system. Remove all sources of sparks, flames, and heat from the area where hydrogen gas is produced or used. Sodium hydroxide is very corrosive to all body tissues, especially eyes. Wear chemical splash goggles, chemical- resistant gloves, and a chemical-resistant apron. The reaction between sodium hydroxide and aluminum starts slowly and then proceeds rapidly with the production of excessive heat. -

Grignard Synthesis of Triphenylmethanol Reactions That Form Carbon-Carbon Bonds Are Among the Most Useful to the Synthetic Organic Chemist
1 Experiment 12: Grignard Synthesis of Triphenylmethanol Reactions that form carbon-carbon bonds are among the most useful to the synthetic organic chemist. In 1912, Victor Grignard received the Nobel prize in chemistry for his discovery of a new series of reactions that result in the formation of a carbon-carbon bond. A Grignard synthesis first involves the preparation of an organomagnesium reagent via the reaction of an alkyl bromide with magnesium metal: δ– δ+ R Br + Mg R MgBr The resulting “Grignard reagent” acts as both a good nucleophile and a strong base. Its nucleophilic character allows it to react with the electrophilic carbon in a carbonyl group, thus forming the carbon-carbon bond. Its basic property means that it will react with acidic compounds, such as carboxylic acids, phenols, thiols and even alcohols and water; therefore, reaction conditions must be free from acids and strictly anhydrous. Grignard reagents will also react with oxygen to form hydroperoxides, thus they are highly unstable when exposed to the atmosphere and are generally not isolated from solution. For a variety of reasons, anhydrous diethyl ether is the solvent of choice for carrying out a Grignard synthesis. Vapors from the highly volatile solvent help to prevent oxygen from reaching the reaction solution. In addition, evidence suggests that the ether molecules actually coordinate with and help stabilize the Grignard reagent: Et Et O R Mg Br O Et Et The magnesium metal used in the synthesis contains a layer of oxide on the surface that prevents it from reacting with the alkyl bromide. The pieces of metal must be gently scratched while in the ether solution to expose fresh surface area so that the reaction can commence. -

Overcoming Challenges in Liquid Dispensing by Using the Right Accessories for Bottletop Dispensers Hanaë A
WHITE PAPER No. 38 Overcoming Challenges in Liquid Dispensing by Using the Right Accessories for Bottletop Dispensers Hanaë A. Henke, Eppendorf AG, Hamburg, Germany Executive Summary In this white paper we give some detailed examples of the beneficial use of the correct accessory with bottletop dispensers and show the possibilities beyond simple single stroke dispensing. Bottletop dispensers are used for multiple applications in the laboratory. Special materi- als must be used for parts getting in direct liquid contact to ensure high chemical resistance against aggressive solutions such as acids, bases and solvents. Additionally special adapters made from ETFE increase the chemical stability. Accessories such as a drying tube protect fuming acids from dilution or alkaline solutions from the forma- tion of carbonates and can be easily attached to bottletop dispensers. The usage of a sterile filter on the bottletop dispenser ensures sterility of the medium in the bottle. Figure 1: A bottletop dispenser with attached flexible discharge tube facilitates filling of small vessels or reagent tubes in a rack. Introduction In almost every laboratory worldwide challenging liquids bottletop dispenser can speed up the workflow and reduce such as acids, bases and solvents are used for various risk of contamination. At the same time usage of less plastic applications. Additionally some liquids need to be sterilized consumables, such as tips, by direct dispensing out of the in advance and kept sterile during dispensing. In routine bottle comes with the benefit of protecting the environment tasks where always the same volume of liquid is required, and saving money. bottletop dispensers can be used to facilitate and accelerate With four exemplary applications with a high demand for work. -
CH 2020 Diels-Alder Reaction: Preparation of a Butadiene Adduct from 3-Sulfolene (Adapted from Organic Chemistry: a Short Course, H
CH 2020 Diels-Alder Reaction: Preparation of a Butadiene Adduct from 3-Sulfolene (adapted from Organic Chemistry: A Short Course, H. Hart, L. E. Craine, D. J. Hart, and T.K. Vinod 13th ed. Houghton-Mifflin, Boston, 2012.) Reference: Bruice, P.Y.,Seventh Edition, Chapter 8. Materials From the Chemicals Hood: From the Stockroom (Blue Bin): 3-Sulfolene ½” “pea-sized” stirbar Reflux condenser Maleic anhydride Stirbar retriever Xylenes Toluene Petroleum ether (60 – 90 °C) 25 mL round-bottom flask Calcium chloride drying Cork ring tube with adapter (2) Wire clips Small metal clamp Introduction The Diels-Alder reaction is a one-step reaction of a conjugated diene and a dienophile, which is reversible. The general reaction and mechanism is depicted in Figure 1. The reaction is the 1,4- addition of an electrophile and a nucleophile to a conjugated diene. However, unlike other 1,4- addition reactions you may have seen, the Diels-Alder reaction is a concerted reaction: the addition of the electrophile and the nucleophile occurs in a single step. This works well because both of the organic substrates are symmetrical. Figure 1. The Diels-Alder reaction to form cis-4-cyclohexene-1,2-dicarboxylic anhydride We will be using 3-sulfolene in our Diels-Alder reaction. 3-Sulfolene thermally decomposes to give the 1,3-butadiene reactant as shown in Figure 2: Figure 2. Thermal decomposition of 3-sulfolene to 1,3-butadiene Procedure Into a 25 mL round-bottom flask, combine 2.0 g 3-sulfolene, 1.2 g powdered maleic anhydride, and a ½” stirbar. Using a pipet, add 1.0 mL xylenes.
