Acyl carrier protein (ACP) from Escherichia coli has been shown to form complexes with melittin, a cationic peptide from bee venom. ACP is a small (Mr 8847), acidic, Ca2+-binding protein, which possesses some characteristics resembling those of regulatory Ca2+-binding proteins including interaction with melittin. Complexing between melittin and ACP which occurred both in the presence and absence of Ca2+ was evident by chemical cross-linking the two peptides, fluorescence changes (including anisotropy measurements), and inhibition by melittin of the activity of a nonaggregated fatty acid synthetase from Euglena. Also, anti-Apis mellifera antibodies which contained antibodies against melittin specifically inhibited the same enzyme system activity relative to non-immune IgG.

The minority carrier lifetime is a valuable parameter for determining the electrical properties of semiconductors. It is particularly useful in the fabrication of solar cells as minority carrier lifetime is directly related to device efficiency. Pump-probe techniques, in which a pump laser of photon energy above the bandgap energy of the material is used to excite free carrier populations while a sub-bandgap probe laser is used to monitor the change in excess carrier density have been demonstrated to be an effective, non-contact, method to measure the minority carrier lifetime, particularly well-suited for use as an in-line measurement apparatus for the solar cell manufacturing processes In this thesis a non-contact, optical, pump-probe method has been used to determine the minority carrier lifetime of float zone and Czochralski grown <100> silicon samples through measurements of modulated free carrier absorption. The equivalence between measurements performed using the transmitted part of the probe beam and those made with the reflected part have been demonstrated on bare silicon wafers, as well as measurement of effective minority carrier lifetime of a completed solar cell, demonstrating the ability of this technique to measure the effective minority carrier lifetime at any stage of the solar cell manufacturing process. / Thesis / Master of Applied Science (MASc)

acase@tulane.edu / The Qatari Maritime Law No. 15 was enacted in 1980. Since then, no amendment has been made to it. It is recommended that this law be revisited in view of the developments that have taken place in the maritime industry. At the national level, the Qatari maritime sector has undergone substantial changes. More importantly, the introduction of a new International Convention on Carriage of Goods Wholly or Partially by Sea (“The Rotterdam Rules”) in 2008 is a second reason for revisiting the Qatari Maritime Law. This is because, such a convention reflects recent advancements in the international shipping industry. This dissertation compares the Qatari Maritime Law provisions of the contract of the carriage of goods by sea to those of international seaborne carriage conventions namely the Hague Rules, the Hamburg Rules, and the Rotterdam Rules. Where relevant, the perspectives of the U.S. and the U.K. will also be examined. There are four major topics analyzed within this dissertation: 1) background information about the State of Qatar in order to set the context, 2) the scope of the application of the rules involved in the comparison, 3) the carrier’s obligations, and 4) liabilities. The main objective of the dissertation is to examine how the Qatari maritime law should be developed in light of the international conventions on carriage of goods by sea. The investigation ends by making some recommendations to the Qatari legislature on how to reform the Qatari Maritime Law so that it is sufficiently robust to cope with modern maritime practice. / 1 / Muna Al-Marzouqi
