Sonae MC: The road model of Kaizen

Sonae MC is considered the first success case of Kaizen in the retail industry. Before becoming a true role model for so many companies, there was a long road to walk. However, it may still be hard to understand the steps taken on the way. How could a training program develop into an integral continuous improvement system, and how did it affect the company – its people, culture, operations and strategy? How was it possible to get everyone on board? How could it be sustained until today, when Kaizen usually fails in the West? What were the critical factors for success?

Genetic algorithm for shipping route estimation with long-range tracking data : automatic reconstruction of shipping routes based on the historical ship positions for maritime safety applications

Ship tracking systems allow Maritime Organizations that are concerned with the Safety at Sea to obtain information on the current location and route of merchant vessels. Thanks to Space technology in recent years the geographical coverage of the ship tracking platforms has increased significantly, from radar based near-shore traffic monitoring towards a worldwide picture of the maritime traffic situation. The long-range tracking systems currently in operations allow the storage of ship position data over many years: a valuable source of knowledge about the shipping routes between different ocean regions. The outcome of this Master project is a software prototype for the estimation of the most operated shipping route between any two geographical locations. The analysis is based on the historical ship positions acquired with long-range tracking systems. The proposed approach makes use of a Genetic Algorithm applied on a training set of relevant ship positions extracted from the long-term storage tracking database of the European Maritime Safety Agency (EMSA). The analysis of some representative shipping routes is presented and the quality of the results and their operational applications are assessed by a Maritime Safety expert.

The Role of the Fbox Protein CG6758 in Xbp1s Induced Retinal Degeneration in Drosophila

The Unfolded Protein Response (UPR) is a signaling pathway that is activated by an accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER) that causes ER stress. The activation of the UPR aims to restore ER homeostasis by attenuation of ER client protein translation, increased transcription of ER chaperones and ER associated degradation (ERAD) factors. If ER stress is too long or too strong, cells may die. The main signaling branch of the UPR is mediated by the ER transmembrane protein IRE1 and the transcription factor Xbp1. The active, spliced form of Xbp1 (Xbp1spliced) acts as a transcription factor with protective function against toxic protein aggregation. However, overexpression of Xbp1spliced in the developing Drosophila eye causes degeneration of the eye (“glossy” eye phenotype).(...)
