The role of ppGpp in E. coli cell size control

Bacteria have been an integral part of human life since the ancient times either as cooperative tenants living in and around us or as constant threats to our health and wellbeing. Since prehistoric times we unknowingly used them as tools of fermentation and fought against them with haphazardly discovered natural remedies. Today, after more than...

Membrane Tension–Mediated Growth of Liposomes

Recent years have seen a tremendous interest in the bottom-up reconstitution of minimal biomolecular systems, with the ultimate aim of creating an autonomous synthetic cell. One of the universal features of living systems is cell growth, where the cell membrane expands through the incorporation of newly synthesized lipid molecules. Here, the...

Dispersal and growth of bacteria

Quantitative experiments with the ability to systematically probe the system under investigation are a key element to gain insight and understanding. We present a novel and simple technique enabling the maintenance and controlled perturbation of experimental conditions of microorganisms from bacteria to nematodes. Polyacrylamide-based devices...

Organisational blueprints for growth in service firms

Start-ups and Smaller and Medium sized Enterprises are vital for national economies. The vast majority of these enterprises can be found in services industries. One of the parameters to measure performance of a company is growth. Only a very small percentage of these enterprises find ways to sustainable growth. Little is known on models for...

A Morphogenetic Approach for Performative Building Envelope Systems Using Leaf Venetian Patterns

Recent developments in theory and technology in performance based design show an interest towards generative systems. In this paper a morphogenetic approach will be introduced that looks at Goethean morphology and leaf venation patterns. To instrumentalize this approach an algorithm will be introduced to generate various leaf venation patterns...

Effect of Arsenic on Photosynthesis, Growth and its Accumulation in the Tissues of Allium cepa (Onion)

Arsenic is a well known carcinogenic element, that can harm not only human health but, plant and bacteria as well. Replicated experiments confirmed that, Arsenic accumulates in the different tissues in different parts of the plant and, adversely affects the growth and productivity of the plants. It is a threat for millions of population in terms...

The Facilitating University: Positioning Next Generation Educational Technology

Higher education is directly and indirectly subjected to pressures of diminishing subsidies, increasing student populations, heterogeneity, shorter knowledge and product lifecycles, labour demands, proliferation of technology, and new educational approaches and practices. Higher education must change to cope with these pressures. This study is...

Growth and metabolism of Anammox Bacteria

The anoxic ammonium oxidation (anammox) process is the conversion of nitrite and ammonium under anoxic conditions- to form dinitrogen gas. The process is performed by deep-branching Planctomycetes. The startup of the first full-scale anammox reactor in the world is described in Chapter 2. The described full scale reactor was a granular sludge...
