Integrated communications strategy for mylabel

Integrated Communication Strategy for MyLabel Following paper presents Integrated Communication Strategy for Continente’s private label brand of cosmetics MyLabel. The main purpose of the project is to position MyLabel as venture brand which will gain strong market position in order to compete with the manufacturer brands. Therefore, based on the created brand equity model for the venture cosmetic brand, MyLabel will be approached from the branding perspective in order to improve perceived quality and consecutively, build brand recognition and credibility. In this respect, integrated communication strategy includes some of the branding tactics and marketing communication mix. Thereafter, MyLabel will be transformed into the sub-brand MyBeauty, which can exploit opportunities given by the new market image of retailers’ brands and gain special, unique position in the market.

Improving building technologies with a sustainable strategy

In recent years it has been noticed the progressive disappearance of vernacular sustainable building technologies all over the world mainly due to a strong urban rehabilitation process with modern technologies not compatible with ancient knowledge. Simultaneously new dwellings are needed all over the world and in this sense it was decided to study an ecological and cost-controlled building technology of monolithic walls that can combine the use of low carbon footprint materials, such as earth, fibres and lime using an invasive species: giant reed cane (Arundo Donax). This paper explains the development of this building technology through testing diverse prototypes.

Impact of carbon/nitrogen feeding strategy on polyhydroxyalkanoates production using mixed microbial cultures

Polyhydroxyalkanoates (PHA) production using mixed microbial cultures (MMC) requires a multi-stage process involving the microbial selection of PHA-storing microorganisms, typically operated in sequencing batch reactors (SBR), and an accumulation reactor. Since low-cost renewable feedstocks used as process feedstock are often nitrogen-deficient, nutrient supply in the selection stage is required to allow for microbial growth. In this context, the possibility to uncouple nitrogen supply from carbon feeding within the SBR cycle has been investigated in this study. Moreover, three different COD:N ratios (100:3.79, 100:3.03 and 100:2.43) were tested in three different runs which also allowed the study of COD:N ratio on the SBR performance. For each run, a synthetic mixture of acetic and propionic acids at an overall organic load rate of 8.5 gCOD L-1 d-1 was used as carbon feedstock, whereas ammonium sulfate was the nitrogen source in a lab-scale sequence batch reactor (SBR) with 1 L of working volume. Besides, a sludge retention time (SRT) of 1 d was used as well as a 6 h cycle length. The uncoupled feeding strategy significantly enhanced the selective pressure towards PHA-storing microorganisms, resulting in a two-fold increase in the PHA production (up to about 1.3 gCOD L-1). A high storage response was observed for the two runs with the COD:N ratios (gCOD:gN) of 100:3.79 and 100:3.03, whereas the lowest investigated nitrogen load resulted in very poor performance in terms of polymer production. In fact, strong nitrogen limitation caused fungi to grow and a very poor storage ability by microorganisms that thrived in those conditions. The COD:N ratio also affected the polymer composition, indeed the produced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) showed a variable HV content (1-20 %, w/w) among the three runs, lessening as the COD:N increased. This clearly suggests the possibility to use the COD:N ratio as a tool for tuning polymer properties regardless the composition of the feedstock.

Nanomedicines, a strategy to evade multidrug resistance

Multidrug resistance is a major problems associated with cancer chemotherapy. Efflux transports is one of the numerous mechanisms involved in multidrug resistance. P-glycoprotein is a transmembrane protein, responsible for drug efflux, which decreases drugs intracellular bioavailability, consequently decreasing their efficacy against cancer. Cancer growth and dissemination depends on the expression of transcriptional factors such as, Twist. Among other features, this protein is related with cells chemoresistance possible by regulation of multidrug resistance pathways including the P-glycoprotein expression. The herein study proposes to demonstrate if paclitaxel entrapped nanoparticles is an effective system in evading multidrug resistance mechanisms and if functionalization of a specific antibody against cancer stem cells receptors (anti-CD44v6) has the capability to target selectively these cells increasing nanoparticles efficacy. Therefore solid lipid nanoparticles were prepared and a breast cancer cell line (MDA-MB-436) was exposed to them in order to assess unloaded nanoparticles cytotoxic effects, increased pharmacologic efficacy of loaded nanoparticles relative to the free drug and their ability to evade multidrug resistance. The proposed solid lipid nanoparticles system proved to be capable of efficiently evading multidrug resistance mechanisms; however no improvement was added when these nanoparticles were functionalized with the antibody in the in vitro studies. However, the nanoparticles system is effective against multidrug resistance mechanisms.

Historic and potential technology transition paths of grid battery storage: Co-evolution of energy grid, electric mobility and batteries

Scarcity of fuels, changes in environmental policy and in society increased the interest in generating electric energy from renewable energy sources (RES) for a sustainable energy supply in the future. The main problem of RES as solar and wind energy, which represent a main pillar of this transition, is that they cannot supply constant power output. This results inter alia in an increased demand of backup technologies as batteries to assure electricity system safety. The diffusion of energy storage technologies is highly dependent on the energy system and transport transition pathways which might lead to a replacement or reconfiguration of embedded socio-technical practices and regimes (by creating new standards or dominant designs, changing regulations, infrastructure and user patterns). The success of this technology is dependent on hardly predictable future technical advances, actor preferences, development of competing technologies and designs, diverging interests of actors, future cost efficiencies, environmental performance, the evolution of market demand and design and evolution of our society.

Impact of chromossomal structure on the evolution of Schizosaccharomyces pombe undergoing Mutation Accumulation

Large chromosomal rearrangements are common in natural populations and thought to be involved in speciation events. In this project, we used experimental evolution to determine how the speed of evolution and the type of accumulated mutations depend on the ancestral chromosomal structure and genotype. We utilized two Wild Type strains and a set of genetically engineered Schizosaccharomyces pombe strains, different solely in the presence of a certain type of chromosomal variant (inversions or translocations), along with respective controls. Previous research has shown that these chromosomal variants have different fitness levels in several environments, probably due to changes in the gene expression along the genome. These strains were propagated in the laboratory at very low population sizes, in which we expect natural selection to be less efficient at purging deleterious mutations. We then measured these strains’ changes in fitness throughout this accumulation of deleterious mutations, comparing the evolutionary trajectories in the different rearrangements to understand if the chromosomal structure affected the speed of evolution. We also tested these mutations for possible epistatic effects and estimated their parameters: the number of arising deleterious mutations per generation (Ud) and each one’s mean effect (sd).
