Deal Structuring, Term Sheets, and Deal Terms

Aluminium roofing is used for low weight, good strength and weather resistance, easy handling and assembly, for various roofs of industrial and agricultural buildings, residential and family houses, holiday homes, garages and various shelters. Important is very long life, relatively low price and the possibility to choose the colour design according to your taste. The basic form is a natural unpainted finish, which can be used because the aluminium roofing material is not subject to corrosion and is chemically stable. The aim of this research is to verify a suitable method of measuring the colour of aluminium roofing and to determine the basic characteristic values of the most common colours of aluminium roofing sheets. The identification by the CIELAB system makes it possible to characterize the suitability of roofing sheets in terms of reducing the heat gains of the roof structure, thus complementing this very practical information to the RAL colour marking system. This leads to a reduction of the cooling demand of air of the building in the summer. In terms of colour measurement and evaluation, the classical method according to the CIELAB system is where the colour attributes lightness (L-value), redness (a-value) and yellowness (b-value). These values may include the effect of surface gloss (SCI values) or exclusion (SCE values).

Based on the results of validity, practicality, and effectiveness, the development of the POGIL e-worksheet is feasible.

The short timescale of the solar flare reconnection process has long proved to be a puzzle. Recent studies suggest the importance of the formation of plasmoids in the reconnecting current sheet, with quantifying the aspect ratio of the width to length of the current sheet in terms of a negative power of the Lundquist number, that is, , being key to understanding the onset of plasmoids formation. In this paper, we make the first application of theoretical scalings for this aspect ratio to observed flares to evaluate how plasmoid formation may connect with observations. For three different flares that show plasmoids we find a range of values of to . The values in this small range implies that plasmoids may be forming before the theoretically predicted critical aspect ratio ( ) has been reached, potentially presenting a challenge for the theoretical models.

With the purpose of evaluating texture hardening in magnesium alloys, the crystallographic texture and mechanical properties at room and elevated temperatures of extruded bars and rolled sheets were studied. Cast ingots were used as the reference materials, since they exhibited nearly isotropic orientation distribution. Formability of AZ31 sheet was evaluated at room and elevated temperatures by the Erichsen test, conical cup test and forming limit diagram. Strong texture is observed in magnesium wrought materials in which the basal plane is oriented parallel to the extrusion or rolling direction. As a result, tensile strength of magnesium wrought materials increased by 15 to 20% due to texture hardening at room temperature. The AZ31 alloy sheet is highly anisotropic at room temperature with high γ-value above 4, resulting that forming limits in biaxial tension are much lower than those in uniaxial tension. However, this anisotropy decreases with increasing forming temperature and no texture hardening is found at 473 K. In this respect, formability of magnesium alloys sheets in terms of Erichsen and conical cup values is remarkably poor at room temperature but appreciably improves with increasing temperature. Sheet forming of magnesium alloys is practically possible only at the high temperature range where plastic anisotropy disappears.

A visualization approach to the study of singularities on the world sheets of strings is presented. A representation of the world sheet in terms of specified supporting curve is discussed, which enables effective use of the visualization techniques for its study. The desirable ways of future research using computer animation and virtual reality are discussed. >

An experiment and a statistic study was performed considering the effect of two important input parameters (stretching force and stretching speed) on the stretching behaviour of 6061-0 aluminum sheet in terms of thickness reduction ratio in two types of stretch forming process (post stretching and pre stretching). Experimental tests were carried out using a die with V-shape to stretch the sheet at two selected levels of stretching force and stretching speed and according to the design matrices established by the Design of Experiment (DOE) software (Version 10). Two models with two variable parameters, i.e. stretching force and speed were built by using the response surface methodology (RSM) technique for the two cases of stretching (post and pre stretching), then checked statistically for adequacy purpose by analysis of variance (ANOVA) analysis, and appeared good with 95 % confidence level. It was found that using the post stretch forming process generally gives a lower thickness reduction ratio than that for pre stretching process. This explains the advantages of using post-stretching process to stretch the 6061-0 aluminum sheet alloy.

ABSTRACTThis paper discusses the legacy of Stuart Hall’s cultural studies approach to socialist politics. Like many other socialist thinkers, his ideas are the direct outcome of political intervention, often through the form of theoretical practice. Because gaps will always remain between reality and theoretical explanation, political intervention tends to be an overreaction to social change or the underestimation of people’s power. Hall’s political practice cannot therefore be exceptional in that it is far from perfect. This paper attempts to establish a balance sheet in terms of his involvement in the debate on the nature of British society, Thatcherism and neo-liberalism. From this examination, some key concepts will be employed to analyse the nature of Korean society in relation to neo-liberal restructuration and the neo-liberal historic bloc. Discussing Hall’s ideas and applying these to Korea, the paper sets out to demonstrate both weaknesses and strengths in Hall’s thought. The strength consists of his open-ended and empirically sensitive reformation of Marxism. On the other hand, the core weakness is found in his post-Marxist epistemological relativism. The main argument set out here is that, in order to develop and refine Hall’s thought, there should be an ontologically realist position compatible with epistemological relativism. For this difficult task, the concept of needs can be suggested as a fresh starting point.

The structure of the plasma sheet in the distant magnetotail observed by the Geotail satellite is examined. We found that the observed structure of the plasma sheet is often different from the standard Harris‐type plasma sheet [Harris, 1962]. The observed structure can be expressed as a double‐peaked current sheet which has a pair of localized electric currents away from the neutral sheet, i.e., a geometrically thick zero magnetic field region attached to the thin boundary layer with a large magnetic field gradient. This type of the plasma sheet is often observed in the distant magnetotail at radial distances of −50 > XGSM/RE > −125. We discuss a possible model to explain the formation of the double‐peaked current sheet in terms of large‐scale magnetic reconnection associated with slow shocks.

Hydrothermal synthesis of nanosized bismuth niobate and enhanced photocatalytic activity by coupling of graphene sheets

The dynamics of relativistic strings is studied with emphasis on the close analogy with the transverse motion of the conventional stretched string of freshman physics. A constraint-free parametrization of the world sheet in terms of arbitrary wave packets moving along the string is given. In particular, it is found that for the initial condition of right and left moving wave packets in a collision arrangement, there is no scattering−each packet only experiences a delay upon passing through the other. Also discussed is the geometry of the spontaneous singularities generically arising for strings in two spatial dimensions.

Seismic assessment of RC structures having shape memory alloys rebar and strengthened using CFRP sheets in terms of fragility curves

Agribusiness Economics: Advances in Renewable Energy and Global Sustainability presents a cross-cutting and systemic approach for the interdependent issues of health, the environment, agriculture, management and economics. It begins by characterising the global food system, identifying structural trends and emerging transformations, elements of permanence as well as opportunities for change. The author asks: how will these factors of change combine with trends of permanence? The book seeks to identify and analyse the lines of transformation to be followed in order to move towards a more sustainable diet. The book also examines the potential for renewable energy production in the agricultural sector. It shows the plurality of issues at this level: economic, financial, technological, social acceptability, training, use and access to agricultural land. It draws up a balance sheet in terms of environmental impact, yield, adaptation of public policies and technological prospects at the international level. Increasingly, agriculture will have to move towards agroecology and agroforestry—the only way of using land that combines trees and crops, which has the beneficial advantages of soil protection as well as the preservation of biodiversity and land productivity.

The research objective is to identify primary history students' readiness to use QR code-based e-job sheets in terms of knowledge, experience, and supporting facilities. The research material consists of digital technology devices, smartphones, internet networks, electronic worksheets, QR Code applications, and an assessment of historical learning. This research applied a quantitative approach. Research respondents included significant history students at the Faculty of Social Sciences Universitas Negeri Padang from 2018 to 2022, including 140 students. Data were collected through a Google Form application questionnaire and shared with the students via WhatsApp. The data were analyzed quantitatively by using percentages and averages. General findings showed that many students were ready to use QR code-based e-job sheets, but others still needed them. The particular findings included: 1) more than half of respondents knew what the e-job sheet was, but two-thirds of them had no experience using the e-job sheet, 2) related to QR codes, it was found that half of the respondents knew what QR code was, but a part of them had no experience using QR codes, and 3) two-thirds of the respondents stated that supporting facilities such campus internet and their smartphone were unable to support the use of QR codes-based e-job sheets. QR code-based e-job sheets have become essential in optimizing digital technology in learning activities. Further research is needed to measure the effectiveness of using QR code-based e-job sheets as an alternative strategy and instrument for assessing learning outcomes in the digital era.
