In 1934 Hume-Rothery, Mabbott and Channel-Evans discussed the factors affecting the formation of primary solid solutions in silver and copper, and concluded that the predominant factors were the atomic diameters and valencies of the solvent and solute elements. In a later paper (Hume-Rothery and Raynor 1938) it was shown that the same considerations applied to the formation of solid solutions in magnesium, provided that due allowance was made for the highly electropositive nature of this metal. In the case of copper and silver alloys, where general valency effects are marked (Hume-Rothery et al . 1934), Hume-Rothery, Lewin and Reynolds (1936) carried out an investigation of the mean lattice spacings of primary solid solutions of cadmium, indium, tin and antimony in silver, and of zinc, gallium and germanium in copper. It was found that, to a high degree of accuracy, equal percentages of cadmium, indium, tin and anti­mony expanded the lattice of silver by amounts proportional to 2 : 3 : 4 : 6 respectively. Zinc, gallium and germanium in equal atomic concentration in copper expanded the copper lattice by amounts proportional to 3 : 4 : 4.8. These factors have been confirmed by Owen and Roberts (1939) and shown also to apply at high temperatures. The factor for germanium in copper was, however, given as 5.

The temperature requirements and availability of host-plants of Euploea core corinna [E. core] (a polyphagous species that attacks Nerium oleander, Hoya sp. and Stephanotis sp. grown as ornamentals in suburban gardens) were studied in Australia. Low temperatures could restrict the distribution of the danaine in southern Australia, and high temperatures exclude it from much of inland Australia. Non-availability of host-plants could also restrict distribution in some places; some introduced host-plants may serve to enlarge the distribution and local breeding activity of E. core.

Seawater Greenhouse

In arid climates, extremely high temperatures in the summer and the chronic water scarcity put a firm barrier against agricultural development and sustainability. The SWGH technology is an engineering phenomenon that came to overcome both the constraints particularly in areas where seawater is accessible and/or brackish groundwater is available. It is a greenhouse used to cultivate crops and at the same time produce its own freshwater need. This study aimed to highlight the models that were carried out to simulate the SWGH as a whole or only the dehumidification rate of the SWGH condenser. Four types of simulation models were identified, namely, analytical, numerical, empirical and artificial neural network simulations. The factors affecting the dehumidification rate were also discussed taking into consideration the results from the simulation models.
