The fibrous plants can grow from Northern to Southern Arctic Circle. Different parts of these lignocellulosic plants are valuable sources of lignocellulosic fibres used in textiles and eco-friendly composites, sources of human food, nutrients, animal feed, agro-fine-chemicals for cosmetics and other area of application. That they are completely sustainable, renewable, and biodegradable and they recycle the carbon dioxide (CO2). Fibrous plants were well known to mankind more than 7 000 BC. Some of these bast fibrous plants like flax and hemp could be explored for reclaiming the soil polluted by heavy metals. The total production of all natural fibres is expected at the level 35-40 million tons/year. Special treatment and functionalization of these fibres provides new promising features and expected new properties of these fibres. Natural fibres can be processed for production of woven goods, knitting, nonwoven, technical and 3D textiles, also as the reinforcement of more friendly composites. These whole plants and woody parts (shives) and fibres can be used for production of special pulp and paper and seeds some for obtaining the agro-fine-chemicals. Natural fibres and derived products have very important properties like: excellent air permeability, high hygroscopicity, high heat absorption, no release of substances harmful for health, they not cause allergy effect, as well as safer behaviour in flame and fire combustion versus man-made fibres. The new emerging method of genetic modification (GM) of these fibrous plants provides promising performance e.g. higher level of cellulose, possibility of creating polyhydroxy-alcanate (PHA) natural polyester in statu nascendi. Such GM modified plants are resistant to special herbicides, better resistant to drought also with controlled level of lignin and pectin.In 21st century the coexistence and competition between man-made and natural fibres is stabilized, especially in area of quality, sustainability and economy of their production.

In recent years, concrete repair has become an integral part of the construction industry. With the vast quantity of concrete used in the South African construction industry over the past 100 years, one can expect an increase in repair and rehabilitation requirements during the extended lifecycle of exposed concrete structures. Crack repair, re-profiling of spalled areas and surface sealing with polymer related materials forms the bulk of such repair and rehabilitation operations. Due to the complexity of these projects and the variety of professionals and other stakeholders involved from the diagnostics to the implementation phase (specialists consultants, contractors, suppliers and owners of the structures), considerable problems seem to have surfaced to ensure cost-effective but sustainable and durable outcomes. It has been found that in many concrete repair projects, the responsibility for the repair work, adequate quality control and the assessment of successful patch repairs are not fully embraced by the various stakeholders.This concern has led to the research as reported in this paper. The research entailed a series of questionnaires drawn up specifically for the four different stakeholder sectors of the concrete repair industry. The results indicate that, although there is agreement that concrete repair is a highly specialized field, there is not enough training in the correct use of the repair materials, nor enough knowledge regarding the diagnostics or material specification and selection processes. Knowledge on polymer modified mortar are also minimal. These problems are compounded by inadequate quality control and lack of ongoing monitoring of patch repair failure. The paper concludes with suggestions on the way forward.

Today’s engineering demands the collaboration of various specialists in order to provide quality excellence and meet time constraints within engineering projects. Even though mechatronic engineering methodologies display handy instruments (e. g. VDI 2206), they are not sufficiently supported by digital engineering tools. Digital engineering tools are rather characterized based on its discipline-specific functions and omit a holistic mechatronic thinking. On this account, the paper introduces a reference model for mechatronic engineering tools. Thereby, the model boundary bases on mechatronic principles and concepts (e. g. the mechatronic principle of interdisciplinary collaboration and the concept of interdisciplinary knowledge provision). The model is structured into three reference perspectives: Process, application and artifact. While the reference perspective process claims the requirements of mechatronic engineering processes, the reference perspective application represents the interaction with mechatronic developers and the reference perspective artifact forms the digital representation of mechatronic production systems. Being designed deductively, industry-based expert interviews and workshops ensure feasibility of the paper’s approach. Finally, the potential for integration in current software maturity models and the company-specific scaling of engineering tools is mentioned as part of the application’s scope.

This paper reveals the popular error and problem in optimization design of helical springs. Most of the engineers and researchers regard wire diameter d, mean coil diameter D and number of active coils n as design variables in the mathematical model of optimization design for helical springs. In fact, only two variables are independent variables in the three design variables. The dependent variable in the optimization design model influences the behavior of the systems to be optimized, which is also possible to calculate wrong results. This paper analyses relationship of wire diameter d, mean coil diameter D and number of active coils n. To take number of active coils n as the dependent variable is reasonable. It can lead to wrong results to take n as the independent variable. The right independent variables in optimization design of helical spring are wire diameter d and mean coil diameter D.
