Published: July 2023

Abstract
After powder metallurgy and carbon/carbon brake materials, carbon-ceramic brake material (C/C-SiC) is a new generation of braking material. There are currently some batches of brake materials whose friction performance could be better: slightly higher than the standard. SiC was introduced into the C/C-SiC brake disc through Polymer Impregnation and Pyrolysis (PIP), and the composition and friction-wear performance C/C-SiC-SiCp were investigated. The findings indicate that the SiC introduced by PIP is amorphous, existing in the material’s pores, and the porosity is reduced to 7%. With the increase in speed, The C/C-SiC-SiCp braking curve demonstrates a transition from inverted trapezoidal to saddle-shaped. The line wear rate is reduced by 0.6 μm/cycle at medium and high speeds compared with C/C-SiC.

Authors: Zhou Chulu , Chen Wei , Wang Lijie , Zhang Guangzhao 
Published: July 2023

Abstract
Glass fiber is an important component of resin composites and greatly affects the properties of materials. UV-cured pipe rehabilitation lining materials prepared by hand lay-up process using glass fibers with different areal densities and weaving types were studied in this paper. Their thermal stability and mechanical properties, such as flexural strength, flexural modulus, and tensile strength, were studied. The results show that the glass fiber-reinforced UV-cured lining material has good thermal stability at 300°C. With the glass fiber areal density increase, the lining material’s flexural strength, and modulus increase. Compared with the plaid stitch-bonded felt and the plaid lapped felt, the higher degree of bonding between warp-knitted stitch-bonded felt and resin can significantly improve the flexural strength and tensile strength of the lining material.

Published: July 2023

Abstract
A series of polycarboxylate ether (PCE) based superplasticizers with early-strength functional monomers were prepared to study the influence of early-strength PCE on the hydration heat of cement, early strength properties, and setting time of concrete. It was found that PCE containing DAC and UP-152 had the most obvious improvement in the early strength performance of concrete, greatly improved the dispersibility of cement particles, accelerated the formation of C-S-H gel, enhanced the early hydration performance, and early advanced the setting time of concrete. It can also reduce the pores and gaps in the cement concrete and improve its compactness. Finally, it had the most prominent effect on the early strength of concrete.

Published: July 2023

Abstract
As an important energy application material, 12MnNiVR steel plate is widely used in the manufacture of crude oil storage tanks. In this paper, in order to explore the causes of unqualified 12MnNiVR steel plate, the samples of unqualified steel plate and continuous casting slab in the same furnace were analyzed by means of metallographic microscope, scanning electron microscope and energy spectrum analysis. There is serious alloy element segregation in the continuous casting slab and steel plate, and the abnormal structure enriched in the segregation zone leads to internal microcracks, which further expand in the subsequent rolling process. The segregation of large sulfide inclusions in the micro cracks and porosity of the continuous casting slab seriously. There are also high-grade looseness in the continuous casting slab, which is not fully welded in the rolling process. As a crack source, it expands and cracks in the cooling process of the steel plate heat treatment, which is also the main reason for the unqualified steel plate flaw detection.

Published: July 2023

Abstract
Polylactic acid (PLA) has good biocompatibility and biodegradability, which is widely used in fused deposition modeling (FDM) technology. But its disadvantages are also very prominent, such as low strength, and high brittleness. Stainless steel material has high mechanical properties and good biocompatibility, so PLA/stainless steel composite material has the advantages of both materials. In this paper, the effects of FDM forming parameters, such as nozzle temperature, extrusion speed, printing speed, nozzle height from the substrate, layer thickness and nozzle diameter, on the single-channel direct writing forming quality were studied from the angle of line height and line width of PLA/stainless steel composites. The results show that selecting appropriate FDM process parameters can effectively improve the quality of single-channel molding, and the printed lines have certain shrinkage. The ratio of line height to line width exceeds 100%. It provides a theoretical reference for the subsequent forming of PLA/stainless steel composite parts based on FDM.
A Numerical Simulation of the Hot Isostatic Pressing of Ti-6Al-4V powder considering the uneven powder distribution
Authors: Meng Fandi , Lang Lihui 
Published: July 2023

Abstract
In the process of powder hot isostatic pressing (HIP), there is always an error between the actual shrinkage of powder and the predicted value of numerical simulation. To explore the cause of this error, a numerical model is established to simulate the HIP process. The initial relative density of the powder is usually set to 0.65, which we think is the main reason for the error. So in this simulation, the initial relative density is subdivided into 4 gradients to simulate the uneven distribution in the capsule. By comparing the simulation and experiment results, we find that different relative densities have a great influence on the final powder densification. The maximum error of the simulation with the usual initial relative density setting of 0.65 is 4.2%. However, considering the uneven distribution of initial powder, the maximum error is reduced to 3.16%, and the average error is also less than 2%

Abstract
Indoor air pollution is found to be twice more dangerous as air pollution in the environment, especially 80-90% of people when they are indoors. Children are more susceptible to diseases caused by poor indoor air quality. Typically, students spend 60-90% of their time indoors, with most of the time at school. The targeted study areas are Telkom Education Areas such as VHS, SHS, JHS, and Tourism-VHS. The assessment procedure used a standard protocol developed by the US EPA (United States Environmental Protection Agency). The measuring parameters are CO2, CO, PM2.5, RH, and T. There are four systems at potential points with a height of 1-1.5 meters above the floor surface (human breathing zone). The indoor air quality assessment results show that almost all rooms have CO2 concentrations exceeding the standard (>1000 ppm). All rooms in Tourism-VHS exceed the PM2.5 concentration standard (>35 μg/m3), and each room has open ventilation, except for room type C (kitchen). Only three rooms exceed the CO concentration standard (>9 ppm), Tourism-VHS type A to C. It is necessary to conduct further research with normal daily conditions, and the measurements also need to be conducted for approximately three days for more data.

Published: July 2023

Abstract
The human population explosion and rapidly increasing urbanization are two major problems of the current century. According to an estimate world human population is about 8 billion, while in the previous century, it was about 2.0 billion. These figures and facts shows that the future impacts of anthropogenic activities will be more harsh and comprise a more complex nature. Carbon emission induced in environment by anthropogenic activities is major cause for global warming. Climate change, different types of environmental pollution, wastage of raw materials, and ecosystem degradation are major important ecological challenges which are being faced by humanity. These problems are increasing every year due to increasing human population. Forests represent one of most frequent types of green area in cities. Their environmental settlement include perfection in air, water and soil quality, conservation of energy, carbon sequestration, low air temperatures, reduction in ultraviolet radiation and reduction in environmental pollution especially air pollution. The political ecology approach is based on interactions between humans and nature, talking about climate change mitigation and adaptation and technologies that are used for these purposes. Many environmental experts have initiated concept of green revolution to achieve mitigation and adaptation strategies. If human population explosion and establishment of new industrial structures go on increasing without considering the importance of trees then certainly there would be more critical changes for living organisms on surface of the earth in near future. So, “green revolution is the best solution to arrest the environmental pollution” in this changing climate of the world.
Univali’s Biguaçu Campus: The first Campus in Brazil to generate 100% of its energy
Authors: Santos Camila Monteiro , Dadam James , Rosa Angelica Pattel da 
Published: July 2023

Abstract
Univali is a communitarian higher education institution located in the south of Brazil. It has seven campuses spread along the coast of Santa Catarina. One of those campuses is located in the city of Biguaçu, and was the first university campus in Brazil to be 100% energy-autonomous. Since 2018, the Biguaçu campus operates with 596 solar panels which occupy an area of 1.000m2. Such structure produces 196MWh per year, and is responsible for the campus’s energy full autonomy. This institutional concern meets the values foreseen in Sustainable Development Goal number 7 from the United Nations 2030 Agenda, which aims to ensure access to clean sources of energy. The major part of Brazilian electricity production is obtained from hydroelectrical plants, and, regardless of the fact that it is considered a clean source of energy, the impacts for the plants’ implementation are usually large. In this sense, the use of solar panels is cleaner and less damaging to the environment. For that, it is believed that Univali’s experience in solar energy generation represents best practices in the energy indicator of UI GreenMetric. The article aims to demonstrate Univali’s experience in having the first campus in Brazil to be completely energy efficient. In order to achieve its goals, the article is written based on literature review and the analysis of institutional and governmental data.
Water Management to Cope with the Effects of Climate Change Best practices in Water Management at Wageningen University & Research
Authors: Luttik Joke , Maters* Erna 
Published: July 2023

Abstract
Wageningen University & Research studies the causes of heavy rainfall and droughts and is looking for solutions to these phenomena [1]. For example, green spaces in the urban environment ensure that water can be drained into the ground. Storage of water is also important, because not only the number of heavy rains is increasing, also there are longer periods of drought. On WUR Campus, these principles of coping with flooding and drought are applied. There is a sizeable area of green space which serves as a groundwater discharge area. The large ponds on campus are used to collect and store excess surface water. During droughts the ponds retain water on campus. In two campus buildings, rain is harvested for flushing toilets and watering inner gardens. The rainwater is harvested from rooftops and stored in underground water tanks. A natural garden was laid out in 1998, and four years ago a natural wetland garden was added to the campus.
The effects of climate change, such as droughts and rising sea water levels affect freshwater supplies, which makes efficient use of water increasingly important. WUR aims to reduce consumption of tap water every year, by increasing water use efficiency and switching to sources other than tap water.

Authors: Friman Mervi , Salminen Janne 
Published: July 2023

Abstract
Sustainable development (SD) strategy of HAMK has directed e.g. developing energy efficient solutions among other sustainability efforts in the university. Participating in GreenMetric rankings gives us useful data to improve comprehensively SD operations of the university. HAMK has long tradition to reduce its ecological footprint: for example, today half of the energy demand is fulfilled by green energy sources bought from the markets. During recent years, less emitting fuel sources and smart energy technologies had implemented on campus. In Finland, national Covid-pandemic actions were closed entire campuses for months, and hence energy consumption (heating and electricity) reduced even during cold winter-spring season. Evidently, above responsible actions have positive impact to the energy budget of the university. However, the university continuously developing pandemic-independent smart energy solutions for possible forthcoming energy crises as well as demands for the carbon neutrality (e.g. EU’s Green Deal). Multidiciplinary research (an ecological handprint) for the energy industry sector for climate-wise solutions are in the focus of many RDI-projects and are included in the HAMK’s strategic research agenda. Multiple energy sources (fuels) and balance in energy costs increase university’s resilience in uncertain future.

Published: July 2023

Abstract
Environmental sustainability does not mean living without luxuries but rather being aware of consumption of resources in a way that is environment friendly. Carbon footprint is one of the many environmental traces that has come to prominence because of its connection with global warming and subsequently climate change as the most renowned environmental indices. In 2018, prior to pandemic period, the University of Balochistan (UoB) participated for the first time in the UI Green Metrics world universities ranking and stood 346 globally and fourth position in Pakistan. It was recorded before the pandemic period that 19.12 Metric Ton (MT) per year of carbon footprint was produced within the premises of the UoB. Multiple interventions were carried out after post pandemic period such as to develop policies to (a) reduce carbon footprints, (b) increase the use of energy saving appliances, (b) recycling of wastewater, (c) regular plantation, and (d) conservation strategies for existing 400 pine trees, greenbelts and ornamental plants. It is suggested that universities may adopt the energy efficient criteria of UI GreenMetric with a focus of public awareness towards reduction in Global Warming Potential (GWP), Climate Change by sustainable universities model.

Published: July 2023

Abstract
The complexity and dynamicity of our world calls for institutions to be more creative and research-driven to surmount global challenges in the education system. Institutions now need to be innovative and creative to be successful, but while the idea of success has changed, the education system especially in Africa has not always adjusted to its methods or goals to meet the ever changing world. In the pre COVID-19 era, many tertiary institutions within Africa did not perceive the need to adopt and invest in ICT education for teaching, learning and research. This unprecedented situation has shined a harsh light on the vulnerabilities, challenges, weaknesses of the Education system and our unpreparedness for a paradigm shift from the conventional teaching classroom methods to digital and then distance learning. In recent times, the campaign for adoption of sustainable practices within universities has been critically championed to prevent future occurrences of education disruption. In the post pandemic era, African universities should encourage the utilization of ICT technology to transform teaching and learning in order to improve on research and education to prepare students for unexpected occurrences like the COVID-19 pandemic, acquire settings and infrastructure to enhance teaching and learning, adopt a proper waste management policy to reduce climate change and promote all round sustainability as well as energy conservation. This work presents the institutional values and activities of Edo State University Uzairue (EDSU), Nigeria during the pre and post-covid 19 era with a strong understanding of the role of sustainability in achieving our goal. EDSU success story was also explored and presented in line with the role of ICT and learning management system for resource optimization and development of a green system through the adoption of energy conservation protocols, developing waste management policies, conservation of biodiversity and aligning with the global net zero emission initiative.

Published: July 2023

Abstract
The lack of eco-industrial development in rural areas demonstrates how isolated these people are from outside networks and resources. The ecological industrial management of clove leaf essential oil run by rural communities within the network is further revealed and analyzed in this study using the social network analysis approach. The findings of this study show how networks are crucial to understanding interactions between subgroups, density, and centralization. This study also implies that strengthening internal social networks inside rural communities, particularly subgroup interactions, must go hand in hand with initiatives to broaden external social networks. While preserving the sustainability of rural ecosystems, strengthening the social networks of rural eco-industries will also create new employment opportunities.
