In this article Piero Formica examines the difference between incremental and revolutionary innovation, distinguishing between the constrained ‘path finders' and the unconstrained ‘path creators’. He argues that an acceptance of ‘ignorance’ and a willingness to venture into the unknown are critical elements in radically creative innovation and entrepreneurship.

Purpose The purpose of this paper is to identify and compare cost and carbon critical elements of two office buildings, and to help achieve an optimum balance between the capital cost (CC) and embodied carbon (EC) of buildings. Design/methodology/approach Case study approach was employed to study cost and carbon critical elements of two office buildings as it allows an in-depth and holistic investigation. Elemental estimates of CC and EC were prepared from BoQs of the two buildings by obtaining rates from the UK Building Blackbook. Pareto principle (80:20 rule) was used to identify carbon and cost critical elements of the two buildings, and the significance hierarchies of building elements were compared. Findings Substructure, frame and services were identified as both carbon and cost critical elements responsible for more than 70 per cent of the total CC and EC of both buildings. Stairs and ramps, internal doors and fittings, furnishings and equipment were identified to be the least carbon- and cost-significant elements contributing less than 2 per cent of total CC and EC in both buildings. The hierarchy of cost and carbon significance varies between buildings due to the difference in the specification and design. Originality/value The increasing significance of dual currency (cost and carbon) demands cost and carbon management during the early stages of projects. Hence, this paper suggests that focusing on carbon and cost-intensive building elements is a way forward to keep both cost and carbon under control during the early stages of projects.

It is a fact that the concept of innovation, which is a necessity in every field today, is now indispensable in the sports sector. Especially, it is thought that determining the relationship between the innovation skills of the students in sports education institutions and the entrepreneurship of the students who are candidates to work in the sports sector is important in the development of innovation awareness of the students who will work in this field in the future. The aim of this study is to examine the relationship between innovation and entrepreneurship skills of individuals who receive sports education according to different variables. The study group was formed by the voluntary participation of 240 people, 161 males (67.1%) 79 females (32.9%), studying at the School of Physical Education and Sports at Istanbul Gelişim University, and selected by the purposeful sampling method. In addition to the personal information form, the Individual Innovativeness Scale (IIS) developed by Hurt et al. (1977) and adapted into Turkish by Sarıoğlu (2014), and the Entrepreneurship Scale (ES) developed by Yılmaz and Sünbül (2009) to measure the entrepreneurship levels of university students were used as data collection tools. After the data showed normal distribution, T-Test, ANOVA and Pearson Correlation Test were used in the analyses, and the Tukey test was used to determine the difference between the groups. According to the results, it was determined that the innovation skills and entrepreneurship levels of the individuals’ varied according to different variables. As a result, it was determined that as the innovation skills of students studying at institutions providing sports education increased, their level of entrepreneurship also increased.

At designing aircraft, much attention is given to the wing, as one of the most critical elements of the airframe. It is necessary to have a clear-eyed outlook at response sequence, efficiency of various factors and calculation features on the receipt timing and quality of the result. In addition, the design of a structural element is a complex multidisciplinary task affecting various fields of science, which is complicated by the use of polymer composite materials. In the furtherance of solving the urgent task of the methods of designing of a polymer composite wing, it is necessary to determine the influence of wing deformation on the airload used in the calculation and determination of product parameters. Methods of designing of a polymer composite wing used at the initial stages and taking into account the choice of the external appearance, justification of the structural arrangement and load-bearing elements. The paper considers the flow of air over the wing of a passenger airliner and analyzes the pressure values for various flight modes. A comparison is made of the initial theoretical wing surface and deformed during flight, and the difference in loading of the considered options is determined. A future methodology of polymer composite wing design based on parametric modelling will take these results into account and make use of them.

Origin Of The Moon

The difference between average densities of the Moon and Earth was interpreted in the preceding report by Professor H. Urey as indicating a difference in their chemical composition. Therefore, Urey assumes the Moon's formation to have taken place far away from the Earth, under conditions differing substantially from the conditions of Earth's formation. In such a case, the Earth should have captured the Moon. As is admitted by Professor Urey himself, such a capture is a very improbable event. In addition, an assumption that the “lunar” dimensions were representative of protoplanetary bodies in the entire solar system encounters great difficulties.

AbstractThe oldest cell-like structures on Earth are preserved in silicified lagoonal, shallow sea or hydrothermal sediments, such as some Archean formations in Western Australia and South Africa. Previous studies concentrated on the search for organic fossils in Archean rocks. Observations of silicified bacteria (as silica minerals) are scarce for both the Precambrian and the Phanerozoic, but reports of mineral bacteria finds, in general, are increasing. The problems associated with the identification of authentic fossil bacteria and, if possible, closer identification of bacteria type can, in part, be overcome by experimental fossilisation studies. These have shown that not all bacteria fossilise in the same way and, indeed, some seem to be very resistent to fossilisation. This paper deals with a transmission electron microscope investigation of the silicification of four species of bacteria commonly found in the environment. The Gram positiveBacillus laterosporusand its spore produced a robust, durable crust upon silicification, whereas the Gram negativePseudomonas fluorescens, Ps. vesicularis, andPs. acidovoranspresented delicately preserved walls. The greater amount of peptidoglycan, containing abundant metal cation binding sites, in the cell wall of the Gram positive bacterium, probably accounts for the difference in the mode of fossilisation. The Gram positive bacteria are, therefore, probably most likely to be preserved in the terrestrial and extraterrestrial rock record.

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.

Ideal Method

Although difference Fourier techniques are standard in X-ray crystallography it has only been very recently that electron crystallographers have been able to take advantage of this method. We have combined a high resolution data set for frozen glucose embedded Purple Membrane (PM) with a data set collected from PM prepared in the frozen hydrated state in order to visualize any differences in structure due to the different methods of preparation. The increased contrast between protein-ice versus protein-glucose may prove to be an advantage of the frozen hydrated technique for visualizing those parts of bacteriorhodopsin that are embedded in glucose. In addition, surface groups of the protein may be disordered in glucose and ordered in the frozen state. The sensitivity of the difference Fourier technique to small changes in structure provides an ideal method for testing this hypothesis.

We have studied the destruction of rabbit muscle actin filaments by osmium tetroxide (OSO4) to develop methods which will preserve the structure of actin filaments during preparation for transmission electron microscopy.Negatively stained F-actin, which appears as smooth, gently curved filaments in control samples (Fig. 1a), acquire an angular, distorted profile and break into progressively shorter pieces after exposure to OSO4 (Fig. 1b,c). We followed the time course of the reaction with viscometry since it is a simple, quantitative method to assess filament integrity. The difference in rates of decay in viscosity of polymerized actin solutions after the addition of four concentrations of OSO4 is illustrated in Fig. 2. Viscometry indicated that the rate of actin filament destruction is also dependent upon temperature, buffer type, buffer concentration, and pH, and requires the continued presence of OSO4. The conditions most favorable to filament preservation are fixation in a low concentration of OSO4 for a short time at 0°C in 100mM sodium phosphate buffer, pH 6.0.
