Rapid global population growth has led to an exponential increase in the use of disposable materials with a short life span that accumulate in landfills. The use of non-biodegradable materials causes severe damage to the environment worldwide. Polymers derived from agricultural residues, wood, or other fiber crops are fully biodegradable, creating the potential to be part of a sustainable circular economy. Ideally, natural fibers, such as the extremely strong fibers from hemp, can be combined with matrix materials such as the core or hurd from hemp or kenaf to produce a completely renewable biomaterial. However, these materials cannot always meet all of the performance attributes required, necessitating the creation of blends of petroleum-based and renewable material-based composites. This article reviews composites made from natural and biodegradable polymers, as well as the challenges encountered in their production and use.

ABSTRACTCombined field and geophysical data show that plutons from the Bega Batholith are elongate, meridional, wedge-shaped bodies which intruded during a period of regional east–west extension in the Palaeozoic eastern Lachlan orogen, eastern Australia. Plutons within the core of the batholith have intruded coeval, syn-rift sediments and co-magmatic volcanics. The batholith is bound by high-temperature, dip-slip faults, and contains several major NE-trending transtensional faults which were active during batholith construction. In the central part of the batholith, the Kameruka pluton is an asymmetric, eastward-thickening, wedge-shaped body with the base exposed as the western contact, which is characterised by abundant, shallow-dipping schlieren migmatites which contain recumbent folds and extensional shear bands. A shallow (<30°), east-dipping, primary magmatic layering in the Kameruka pluton steepens progressively westward, where it becomes conformable to the east-dipping basal migmatites. The systematic steepening of the layering is comparable to sedimentary units formed during floor depression in syn-rift settings. The present authors suggest that the wedge-shaped plutons of the Bega Batholith are the deeper, plutonic expression of a hot, active rift. The batholith was fed and sustained by injection of magma through sub-vertical dykes. Displacement along syn-magmatic, NE-trending faults suggests up to 25 km of arc-perpendicular extension during batholith construction. The inferred tectonic setting for batholith emplacement is a continental back-arc, where modern half-extension rates of 20–40 mm yr−1 are not unusual, and are sufficient to emplace the entire batholith in ∼1 Ma. This structural model provides a mechanism for the emplacement of some wedge-shaped plutons and is one solution to the ‘room problem’ of batholith emplace

The transportation is the core functional elements in the logistics activities. If not focusing on implementation of eco-friendly management in the process of logistic transportation, it is impossible to build an eco-friendly logistic system as a whole. Developed countries attach great importance to environmental issues and spare no effort in promoting the reform of logistics transportation. In order to comply with sustainable development in society and economy, China's transportation industry is urgently in need of more scientific management. Based on the relevant issues of current logistic transportation, from the perspectives of multi-subject such as the government, the enterprises and the public, this article analyzes the feasible approach to achieving the eco-friendly transportation management to ensure harmonious development of efficient transportation, social economy, environment and resources.

In the Covid Pandemic 19, sharia cooperatives must be a solution for the welfare of their members and the UMKM that they support so that they can move up in class, but how if it is difficult to access, therefore sharia cooperatives must be digital-based and include collaborating with fintech. This study tries to answer the problems that occur, strategies, and stakeholders involved in the development of Islamic cooperatives in collaboration with sharia fintech in Indonesia using the Interpretive Structural Model (ISM) approach. The core problem faced in developing sharia cooperatives in collaboration with sharia fintech is the lack of education and promotion of Islamic financial institutions collaboration, especially in sharia cooperatives with sharia fintech (E9), which initially became competitors to financial institutions because they were very flexible and fast and have become OJK's instructions that fintech must collaborate with financial institutions including sharia ones. Furthermore, it can be suggested for legislators, actors and drafter to constantly monitor and improve the process in the context of the progress and welfare of cooperatives and SMEs in Indonesia.

Purpose Circular economy (CE) has evolved as a result of the growing environmental awareness, environmental legislation and the need for social responsibility. However, awareness levels of CE are not as high as expected and practices are further behind than they should be, with a significant lack of research around the subject in the literature. Therefore, the purpose of this paper is to examine the current state of awareness levels and the practices around CE in manufacturing firms. Moreover, the study aims to empirically validate one of the earlier proposed CE models. Design/methodology/approach The study adopts a quantitative survey questionnaire based approach. More than 500 people from various manufacturing organisations were contacted directly over a 40-day long sampling process through the FAME database, personal contacts and LinkedIn. The survey resulted in 103 completed responses. Given the exploratory nature of the study, the data were mainly analysed using descriptive statistics. To validate the CE model, a correlation analysis was also conducted. Findings The research findings show that with the growing emphasis on CE across the globe by governing bodies, firms are becoming more aware of CE practices. The analysis also shows some useful insights on the state of each of the pillars (economic benefits, environmental impact and resource scarcity) of CE. The findings also indicate that the environmental impact pillar of CE is at a more developed state than the other two pillars which are, mostly, in a research state. Research limitations/implications The study provides manufacturing firms with a thorough understanding of the state of CE practices and importance of its successful implementation. The findings of the study advocates consideration of all three pillars of CE by managers as a guide to plan for an efficient strategy around CE implementation. Moreover, our study adds to existing efforts by the academic community to raise the awareness towards CE practice among all relevant stakeholders. The findings of this study are based on the responses from a limited 103 survey responses from manufacturing firms. Originality/value This study adds to the very limited empirical literature on CE awareness and practices in manufacturing firms. This is also one of the first studies attempting to empirically validate an existing CE model.

Several different methods of using multi-wavelength anomalous scattering data are described and illustrated by application to the solution of the known protein structure, core streptavidin, for which data at three wavelengths were available. Three of the methods depend on the calculation of Patterson-like functions for which the Fourier coefficients involve combinations of the anomalous structure amplitudes from either two or three wavelengths. Each of these maps should show either vectors between anomalous scatterers or between anomalous scatterers and non-anomalous scatterers. While they do so when ideal data are used, with real data they give little information; it is concluded that these methods are far too sensitive to errors in the data and to the scaling of the data-sets to each other. Another Patterson-type function, the P s function, which uses only single-wavelength data can be made more effective by combining the information from several wavelengths. Two analytical methods are described, called AGREE and ROTATE, both of which were very successfully applied to the core streptavidin data. They are both made more effective by preprocessing the data with a procedure called REVISE which brings a measure of mutual consistency to the data from different wavelengths. The best phases obtained from AGREE lead to a map with a conventional correlation coefficient of 0.549 and this should readily be interpreted in terms of a structural model.

Recently the BIM concept that all professionals carry out collaborative work among domains and departments in the industry has attracted more and more attention by research scholars and engineers around the world. The core of the BIM technology is the information sharing and exchanging among the life cycle. In view of this key problem, this article introduces the situation of the BIM research and development in domestic and overseas, and indicates that there are several common problems existing in the BIM development, such as, the information of multiple projects cannot be stored in a centralized database; the information is lost or incorrect when importing and exporting IFC model files with popular BIM software; the application software based on BIM technology is quite few, etc. The paper points out that the realization of BIM technology shall be based on the BIM database which is based on IFC standard. After that, this paper discusses how to build the BIM database based on IFC standard, the application interface of BIM database, the function of budgetary estimates and the transplantation of structural model conversion to BIM database. Then, a few examples are given to demonstrate the feasibility and reliability of the BIM database and corresponding applications developed in this research. As a result, it is concluded that the IFC based on BIM database is the foundation of developing building collaborative platform and digital city.
