Development of design and construction of fishing boats in Uganda

Fishing boats and canoes varied very little in Uganda from the middle of the 19th century umil 1949. types in use being the Dug Out Canoe. up to 40 ft. in length with 4 ft. beam hollowed from trees, and "Sesse" canoes which were used on Lake Victoria; these had an obvious Arab influence. The length of the "Sesse" in recent years as from about 1912 is 28 ft., and it is used as an open fishing craft.

Design of miniaturized wireless sensor mote and actuator for building monitoring and control

In this paper, a wireless sensor network mote hardware design and implementation are introduced for building deployment application. The core of the mote design is based on the 8 bit AVR microcontroller, Atmega1281 and 2.4 GHz wireless communication chip, CC2420. The module PCB fabrication is using the stackable technology providing powerful configuration capability. Three main layers of size 25 mm2 are structured to form the mote; these are RF, sensor and power layers. The sensors were selected carefully to meet both the building monitoring and design requirements. Beside the sensing capability, actuation and interfacing to external meters/sensors are provided to perform different management control and data recording tasks. Experiments show that the developed mote works effectively in giving stable data acquisition and owns good communication and power performance.

Architecture and Construction Management at Queens University Belfast:Regional Cultural Centre

The Regional Cultural Centre in Letterkenny is a new 2000sqm arts center containing theatre, galleries, workshops and ancillary offices. The site is set back from the street, on high ground with good views. The form and envelope of the building was derived from geometrically connecting the site with the town’s two other main public buildings, the Cathedral (1901) and new Civic Offices (2002, also designed by MacGabhann Architects). This geometrical connection or vectors informed the geometry and shape of the building. This urban matrix of geometrically connecting three corner stones of society, namely the ecclesiastical headquarters, the administrative head quarters and the art centre helps to improve the town planning and urban design of the disparate and chaotic development that Letterkenny has become.
The large cantilever, which houses a 300sqm gallery, is aligned towards the Civic Offices, marks the entrance, and signifies a change of direction of the pedestrian route past the building, like a modern day obelisk.
The circulation routes and stairs internally provide views towards the civic offices and cathedral, thus reinforcing the connection between the three buildings and helps visitors make some sense of Letterkenny as an urban center. The main stairs and vertical circulation are contained behind the large glazed foyer, which is framed to be viewed externally like a proscenium stage, with visitors to the building passively acting their routes through the building.

Assessing Lifetime Homes Standards and Part M Building Regulations for Housing Design in the UK

The aims of this article are to examine Lifetime Home Standards (LTHS) and Part M of the UK Building Regulations and to discuss how relevant and successful they are. The UK government expects all new homes to be built to LTHS by 2013. This is increasingly important with an ageing population. The home environment can enable independence and provide a therapeutic place for everyone. As Part M of the building regulations are compulsory in all housing and LTHS are mandatory for public sector housing, a review of research articles was undertaken on these standards. The paper begins with a brief background on accessibility regulations, followed by a critical review of the standards that takes the body of literature that has been written around them into account. This review suggests that the standards should be improved and that designers and architects face challenges to creatively incorporate them into housing design.

Bioinspired iron and manganese catalysts for the effective and selective oxidation of alkanes and alkenes

La gran eficiència, selectivitat i les condicions suaus exhibides per les reaccions que tenen lloc al centre actiu de les metal·looxigenases són la font d'inspiració per la present dissertació. Amb l'objectiu de dissenyar catalitzadors d'oxidació eficients hem fet ús de dues estratègies: la primera consisteix en el disseny de complexos amb baix pes molecular inspirats en aspectes estructurals de la primera esfera de coordinació del centre metàl·lic d'enzims de ferro i de manganès. Aquests complexos s'han estudiat com a catalitzadors en l'oxidació selectiva d'alcans i d'alquens fent servir oxidants "verds" com ara l'H2O2. La segona estratègia està basada en l'ús de la química supramolecular per tal de desenvolupar estructures moleculars auto-acoblades amb la forma i les propietats químiques desitjades. Concretament, la construcció de nanocontenidors amb un catalitzador d'oxidació incrustat a la seva estructura ens permetria dur a terme reaccions més selectives, tal com passa en les reaccions catalitzades per enzims.
