title: Technological development in Therapeutic applications of alternating electric fields: Review

authors: Talele, Sadhana

abstract: A number of bacteria, virus and other unhealthy cells need to be killed for getting rid of them. For more than a century antibiotics have been effectively used for killing bacterial pathogens and chemical drugs against the cancer cells. However, there are bacteria and cancer cells that are drug resistant. This may have to be overcome by other stronger drugs, higher dosage. These can have detrimental side effects. Other non drug methods to aid the effect of these drugs have always been in research. Electrochemotherapy, a method of using electric fields along with the drug to be used topically has been one of the successful approaches. One of the most recent methods of Tumor Treating Frequencies (TTF) for a brain cancer has been FDA approved. This article details the use of TTF. The article also details some other latest research where alternating fields are used as antibacterial agents.

title: Synthesis of a boronic acid anhydride based ligand and its application in beryllium coordination

authors: Buchner, Magnus R.

subjects: Science & Technology

abstract: The synthesis of a boronic acid anhydride‐based ligand containing one three‐ and one four‐coordinated boron atom is presented. This ligand was successfully employed as a tridentate κ¹N,κ²O‐ligand in the coordination of beryllium chloride and both the ligand and the resulting complex have been structurally characterized. While the boron‐element separations are within the typical range of related homo‐nuclear compounds, the corresponding beryllium‐element distances are rather long, suggesting unexpectedly high electron density at the beryllium center. Incorporation of a beryllium atom in a six‐membered ring causes no more distortion than the corresponding boron atom, suggesting that analogous ligand systems could be used in boron and beryllium coordination chemistry. The generated hetero‐tri‐nuclear complex enables the direct comparison of bond lengths and angles at beryllium and boron atoms in similar coordination environments and can act as a monomolecular model for beryllium borates.

title: Dis-lodging literature from English: Challenging linguistic hegemonies

authors: Locke, Terry

subjects: literature

abstract: This paper problematises the location of literature "teaching" within the English (L1) curriculum, as is the case in New Zealand and other settings. It defamiliarises this arrangement by drawing attention to official New Zealand policies of biculturalism and to the increasing cultural and linguistic diversity in many New Zealand classrooms. It identifies a number of social justice issues arising from the current arrangement, and also raises issues in respect of educational policy and ways in which canonical subjects become constructed in practice. It then discusses ways in which a new qualifications template developed at the University of Waikato might provide a vehicle for establishing a new arrangement, in terms of which literature study is dislodged from English and reshaped as a course of study entitled Literature in Society. It indicates ways in which Comparative Literature, as a predominantly university-constituted discipline, might contribute to the theorisation of this new arrangement.
