A Stormwater Overflow Control Device

On Lake Eola, stormwater runoff has been identified as a major source of pollution. Other lakes in Central Florida are experiencing similar decay due to stormwater runoff. A device has been examined for diversion of the initial flows to treatment before discharge into the lake. A graphical aid was developed to select the proper volume required for the device and was applied to a Lake Eola existing collection basin. A laboratory model was designed and constructed based on the scaled-down version of a collecting basin on Lake Eola. This model was used to demonstrate the concept, as well as, indicate the effects of several critical design variables. Recommendations on design for a Lake Eola device were made for possible improvements in the system itself

Planning for High Net-WOrth U.S. Persons Through the Use of Offshore Life Insurance

Sophisticated planning for the high net-worth United States citizens often includes the use of offshore variable life insurance. Such leading edge planning is accomplished through structures that provide income, gift, estate, and generation-skipping transfer tax planning not available domestically. In addition to providing sophisticated tax and estate planning benefits, variable life insurance policies issued by foreign-based carriers have numerous economic advantages

Development and Flight Results from the C3D2 Imager Payload on AlSat Nano

An experimental CubeSat camera system using 3 separate CMOS imagers was flown in 2014 on UKube-1. In response to an announcement opportunity in December 2014, we proposed an upgrade to our C3D imager payload, which was accepted to fly on AlSat Nano. Launched in September 2016 the system has been operational for over 1 year and has returned both images and housekeeping data, including detailed temperature and radiation dosimetry measurements. Through these in-orbit demonstrations on CubeSans, the image sensors and payload have attained TRL9, and these are now being used in other flight opportunities. In this paper we describe the C3D imager payload, which comprises 3 independent CMOS image sensors used in different camera systems; two wide field cameras are specifically optimised with one to observe the Earth from the 650 km orbit, and the other with its focus set to 40 cm to observe a deployable boom from the CubeSat. The experiment controller also contained thermometry and two RADFET dosimeters, one located on the payload, with the other deployed at a different point on the spacecraft. In this paper we will describe the experiment design and operational performance, and review the in-orbit data obtained during the operations covering over 17 months in-orbit, in addition to discussing lessons learned from the flight experience. We also discuss further developments of the payload concept which we are currently working on toward future flight opportunities

Transport numbers and ion mobilities in the fused salt KCl-PbCl2

Values of ionic transport numbers and ionic mobilities were determined for the fused system KCl-PbCl2. Cation transport numbers of 0.24 (525°C) and 0.78 (850°C) were found for PbCl2 and KCl, respectively. In each mixture studied t- deviated positively and both t+ and t++ deviated negatively from linearity when plotted against equivalent fraction. The initial very rapid depression of total equivalent conductance from that of pure KCl, caused by addition of small amounts of PbCl2, was found to be due to the depression of the ionic conductance of K+ rather than complexing between Pb++ and Cl- as had been previously supposed. Values of 0 were comp~red with those in the system LiCl-PbCl2, calculated from available literature data

Voter Model Perturbations and Reaction Diffusion Equations

We consider particle systems that are perturbations of the voter model and show that when space and time are rescaled the system converges to a solution of a reaction diffusion equation in dimensions $d \ge 3$. Combining this result with properties of the PDE, some methods arising from a low density super-Brownian limit theorem, and a block construction, we give general, and often asymptotically sharp, conditions for the existence of non-trivial stationary distributions, and for extinction of one type. As applications, we describe the phase diagrams of three systems when the parameters are close to the voter model: (i) a stochastic spatial Lotka-Volterra model of Neuhauser and Pacala, (ii) a model of the evolution of cooperation of Ohtsuki, Hauert, Lieberman, and Nowak, and (iii) a continuous time version of the non-linear voter model of Molofsky, Durrett, Dushoff, Griffeath, and Levin. The first application confirms a conjecture of Cox and Perkins and the second confirms a conjecture of Ohtsuki et al in the context of certain infinite graphs. An important feature of our general results is that they do not require the process to be attractive.Comment: 106 pages, 7 figure

The catalytic effect of anions on reduction reactions involving metal ions

A model is proposed for a general activated complex AXB in oxidation-reduction reactions involving two metal ions (A) and (B). The symbol (X) would indicate the anions or other groupings which might be present, and which ordinarily would be complexed to the metals separately. The effectiveness of (X) is related to its ability to be oxidized or reduced in itself. In the case that (X) consists of oxidizable anions, the probability of electron transfer from (X) to the oxidizing metal (A) is correlated with the strength (energy) of the bond between (X) and (A). Two previous explanations of the catalytic effect of anions on such reactions are discussed, and some experiments outlined will test the validity of the proposed model

Observations of the Habits of \u3ci\u3eCorthylus Punctatissimus\u3c/i\u3e (Coleoptera: Scolytidae) Infesting Maple Saplings in Central Michigan

Corthylus punctatissimus, the pitted ambrosia beetle, infested and killed maple saplings that were 3-12 years of age with a basal diameter of 4-14 mm. The habits of the parental pair of adults are described. The beetles construct a spiral gallery system with about five egg niches per host. Half the brood reaches adult stage during the summer with a sex ratio of 1:1. No relationship was found between the number of niches, length of gallery system, or diameter of stem
