Opis:
This paper aims to introduce GIS, its definition, principle, application in any discipline particularly maritime, its process, data sets and features and its benefits to maritime and universities. Specifically, the paper intends to provide an overview of its wide applications in maritime including but not limited to marine transportation, marine environment, port management and operation, maritime education and training (MET) and maritime research. GIS simplest task is in mapping and visualization. But its most important function is in spatial analysis. Spatial analysis takes into account the location, geometry, topology, and relationships of geographic data, which lend itself to intelligent decision making. GIS is not just for researchers and students. GIS is especially useful for decision makers such as: managers, administrators, and directors of large and small projects. Scenarios are “seen” and analyzed even before events happen. To planners and decision makers, this is very important because they can assess the impact of events or scenario and may save a lot of time, effort, and money before implementing the actual project. An additional skill on GIS when learned or thought would certainly result to a technically competent maritime global workforce. The paper would provide ideas on possible areas for collaborations among TransNav member institutions for data sharing which may be processed and analyzed by a GIS specialist.

Opis:
Nitrogen fixing bacteria have been used for centuries to improve the fertility of agricultural soils. Since the introduction of inorganic nitrogen (N) fertiliser that provides a reliable boost to crop yields whilst reducing land and labour requirements, the use of biological nitrogen fixation has been in decline. Recently, concerns have been expressed about the sustainability of inorganic N fertiliser application, however, there remain doubts about whether N2 fixing bacteria alone can provide agriculture with sufficient fixed N to feed a burgeoning global population. In this paper we review the current state of our knowledge regarding those diazotrophic bacteria that have a role to play in agriculture. We focus on our current areas of research, particularly, the importance of understanding the classification and mechanism of action of N2 fixing bacteria that are used in agricultural soils. We discuss the applications of N2 fixing bacteria that illustrate their potential to provide sustainable N, particularly focussing on Australian and South American agricultural systems where these bacteria are widely exploited to maintain soil fertility. We also identify problems with the use of bacteria as inoculants, including ineffective inoculation due to poor quality preparation, the use of appropriate isolates and issues with sustainability. We review the outlook for biological N fixation highlighting how molecular biology may enable the expression of N fixation in non-leguminous crops.

Opis:
Purpose: Otosclerosis is a metabolic bone disease of the otic capsule that can cause the stapes fixation, resulting in conductive hearing loss or, in a profound sensorineural deafness threshold. Surgery is one of the possible treatments for the otosclerosis. To repair small focus of otosclerosis in the anterior crus of the stapes, in 1960, Hough suggested the implementation of a technique in which part of the anterior crus is fractured and the stapes turned. As a result, the posterior crus of the stapes is the only connection with the inner ear. In this work, the outcome of Hough’s surgical technique was simulated. Methods: Based on computerized images, a finite element model of middle ear ossicles and tympanic membrane was created, as well as a model where the stapes has changed. The discretization of the tridimensional solid model was made using the ABAQUS software. The mechanical properties used were taken from the literature and adequate boundary conditions were applied. Results: The results obtained with the Hough technique simulation were compared with a representative model of the normal ear, taking into account the displacements obtained on the central part of the stapes footplate and the maximum principal stress in the stapes crus. Conclusions: The results obtained are closer to the normal ear model, therefore Hough technique stands out as a good option to correct small focus of otosclerosis.

Opis:
In this work, the establishment of a technology for HgI2 purification and crystal growth is described, aiming at a future application of this crystal as a room temperature radiation semiconductor detector. Two methods of crystal growth were studied in the development of this work: (1) physical vapor transport (PVT) and (2) saturated solution from dimethylsulphoxide (DMSO) complexes. In order to evaluate the crystals obtained using each of these methods, systematic measurements were carried out for determining the stoichiometry, structure, orientation, surface morphology and impurity of the crystal. The influence of these physicochemical properties of the crystals developed was evaluated in terms of their performance as a radiation detector. The best response to radiation was found for the crystals grown by the PVT technique. Significant improvement in the performance of HgI2 radiation detector was found, purifying the crystal by means of two successive growths by the PVT technique.

Opis:
Marine biological valuation provides a comprehensive concept for assessing the intrinsic value of subzones within a study area. This paper gives an update on the concept of marine biological valuation as described by Derous et al. (2007). This concept was based on a literature review of existing ecological valuation criteria and the consensus reached by a discussion group of experts during an international workshop in December 2004. The concept was discussed during an ENCORA –MARBEF workshop in December 2006, which resulted in the fine-tuning of the concept of marine biological valuation, especially with respect to its applicability to marine areas.
