Vernacular Residential Architecture in the Context of Sustainability – Case Study of Svrzo's House Complex

This paper analyses the presence of sustainable elements in one of the most representative surviving examples of vernacular residential architecture from the Ottoman period, located in Bosnia and Herzegovina. The focus is on the significance of vernacular architectural elements, which can serve as an inspiration for contemporary building design in the context of sustainability. Two main aspects need to be considered: respecting the inter-relationship between humans, nature, climate, and local surroundings, and adaptation of design to the time in which it was created. Svrzo’s house complex, as National Monument, is chosen as a case study, and detailed survey was conducted regarding the presence of sustainable design principles i.e., building form, use of local materials, orientation, adaptation to local climate and topography, passive cooling and natural-induced ventilation, water, and vegetation. A traditional architectural treasure – a functional, simple, and aesthetically valuable concept, shows that ambient requirements were met with minimal energy consumption and material waste from construction to consumption, achieving a responsible ethical attitude towards the environment. The analysis also includes an evaluation of energy efficiency aspects, by comparing the actual heat transmission values of the building elements with the allowable heat transmission values, prescribed by regulation. The actual average heat transmission values are higher which indicates that although the positive impacts of using natural local materials are wide, in terms of enhancing thermal properties, these sustainability features alone are not sufficient to prevent heat losses without proper thermal insulation.

Building on prior methods used to aid correlation of MRI results and whole-mount pathology findings, we have developed an inexpensive and easy to implement means with which 3D-printed molds can be created for any prostate to enable targeted ex-vivo sampling of biopsy-proven cancer lesions seen on MRI. The potential applications for a platform that can reliably sample living prostate cancer tissue are numerous, including the ability to facilitate future cancer research. METHODS: STL files of the prostate boundary and target lesions are exported from the UroNav fusion biopsy system. A custom macro was developed for use with SolidWorks (Dassault Systèmes, France), a computer-aided design application. This creates a material-optimized mold around the prostate with needle guides that allow for targeted sampling of up to 4 regions of interest. The guides are customizable in terms of location and dimensions to accommodate different biopsy needles. The parts are then exported and 3D-printed. Following prostate extraction at time of radical prostatectomy, the seminal vesicles are removed. The prostate is then placed into the mold, and samples are taken by inserting a biopsy needle into a guide up to the predetermined depth. The prostate is then passed to pathology for standard processing, while the live tissue in the biopsy cores is available for a variety of purposes. RESULTS: The resulting platform allows for a prostate of any size or morphology to be precisely sampled as long as there is a pre-acquired MRI dataset. The prostate mold allows for accurate sampling of target cancer lesions and is optimized in size for each prostate to allow for minimal material waste. CONCLUSIONS: This novel platform provides the unique ability to obtain fresh prostate cancer tissue. The utility of this is not necessarily limited to prostate cancer alone but may be of use in other solid-organ malignancies with targetable lesions as well.

A new Coplanar Dual Core Buckling-Restrained Brace

This study presents a new all-steel Buckling-Restrained Brace (BRB) named Coplanar Dual Core (CDC) BRB, that consists of a rectangular cross-sectional core divided into two coplanar yielding lateral bands, whose movements are constrained by an external restrainer (ER) and by an internal restrainer (IR). In contrast with the traditional BRB with dog-bone shaped core, the CDC-BRB has the advantage that the core can be easily extracted and inspected. The ER is composed of two rectangular tubes welded to a pair of rectangular solid calibrated bars. The core and IR are simultaneously laser cut from the same sheet of steel, which provides additional advantages: minimum material waste, minimum laser cut length, regular and well controlled gap, reduction of weight and manufacturing cost. Formulae to design the CDC-BRB, to determine the appropriate values of the gaps, and to predict its response and ultimate energy dissipation capacity are proposed. Four specimens representing the new CDC-BRBs with different gaps are tested under cyclic loadings to failure. The results of the tests show that the cyclic behavior of the new CDC-BRB is stable, highly dissipative, and its response and ultimate energy dissipation capacity can be well predicted insofar the gaps fit the proposed values.

Additive Manufacturing Processes in Selected Corrosion Resistant Materials: A State of Knowledge Review

Additive manufacturing is an important and promising process of manufacturing due to its increasing demand in all industrial sectors, with special relevance in those related to metallic components since it permits the lightening of structures, producing complex geometries with a minimum waste of material. There are different techniques involved in additive manufacturing that must be carefully selected according to the chemical composition of the material and the final requirements. There is a large amount of research devoted to the technical development and the mechanical properties of the final components; however, not much attention has been paid yet to the corrosion behaviour in different service conditions. The aim of this paper is to deeply analyze the interaction between the chemical composition of different metallic alloys, the additive manufacturing processing, and their corrosion behaviour, determining the effects of the main microstructural features and defects associated with these specific processes, such as grain size, segregation, and porosity, among others. The corrosion resistance of the most-used systems obtained by additive manufacturing (AM) such as aluminum alloys, titanium alloys, and duplex stainless steels is analyzed to provide knowledge that can be a platform to create new ideas for materials manufacturing. Some conclusions and future guidelines for establishing good practices related to corrosion tests are proposed.

Pengaruh Salinitas Pasir Terhadap Kuat Tekan Bata

The development of technology, especially in the construction field, in manufacturing bricks is increasingly rapid and varied, one of which is lightweight brick. The light brick is a composite building material made of sand, cement, limestone, gypsum, water, and aluminum powder. In general, lightweight bricks have two types, Autoclaved Aerated Concrete (AAC) and Cellular Lightweight Concrete (CLC). Light bricks were created to lighten the structural load of a construction building, speed up construction, and minimize material waste during the wall installation process. Sand is a staple in the construction process. In addition, sand material cannot be separated from its use in the industrial world. The Taguchi method is a methodology in engineering that aims to improve the quality of products and processes and can reduce costs and resources to a minimum. The compressive strength of the concrete load is the magnitude of the load per unit area, which causes the concrete specimen to collapse when loaded with a specific compressive force, which is generated by the press machine; the compressive strength of the concrete will increase with increasing age of the concrete, where the compressive strength of the concrete will increase rapidly (linearly). Salinity is the salt content dissolved in water which is one of the physical parameters that can affect the quality of water, soil and sand.

COMPARISON OF FORGING LOAD, MATERIAL FLOW AND PRESSURE DISTRIBUTION OF THE UNI-DIRECTIONAL, BI- DIRECTIONAL AND TWO-STEP FORGING PROCESSES

Because of high productivity, closer dimensional tolerances, and minimal material waste precision forging (net or near net shape) processes have been used for manufacturing automobile components. The primary disadvantage of precision forging is the encountered higher tool stresses due to applied higher forging loads. Thus, forging load reduction is a higher priority in precision forging in terms of energy consumption and cost because higher loads required higher investment and higher energy consumption. Forging load is affected by several parameters such as temperature, material flow, the geometry of the billet, and punch movement. In this study, forging load, material flow, and normal pressure distribution in the forged part were investigated considering uni-directional, bi-directional, and two-step forging processes. FEM simulations were performed by using a solid cylindrical billet. To perform FEM simulations, the finite element analysis package (DEFORM 2D) was used. Also, experimental studies of the FEM models were performed. For bi-directional and step-forging experimental studies, a double-acting servo press was used because the movement of the top and bottom punch can be controlled accurately. Then the results of FEM and experimental studies were compared with each other. The results of the FEM simulations and experimental studies show two-step forging offers lower forging load and energy consumption whereas the uni-directional closed die forging process needs higher load and energy consumption

An Intelligent Support System for Additive Manufacturing technology investment decisions

When an unexpected crisis occurs, managers often seek such scientific solutions that can help them to take proactive actions before any threat arises. Crisis can be treated as an increase in the cost of energy consumption, employee rotation, lack of access to technology on account of sanctions. In this article, a system is presented that can aid decision-making when implementing additive manufacturing (AM) technology in a manufacturing enterprise. This technology may be necessary to reduce production process stages, minimize material waste, and optimize production costs in the use of resources. The application allows for analysis of the selected parameters of manufacturing process that are currently in use compared with those parameters of the AM process. The tool can be used to support decision-making in the area of changing manufacturing technology and the implementation of AM technology.

Welding-based additive manufacturing processes for fabrication of metallic parts

Additive Manufacturing (AM) is modernizing the manufacturing industry by enabling the layer-by-layer deposition process to manufacture objects in nearly any form with minimum material waste. However, components developed utilizing the AM process have dimensional constraints. To address this issue, AM-produced metal materials can be coupled with various welding processes. This article focuses on the foundations, highlighting the distinguishing features, capabilities, and challenges of welding-based AM processes by categorizing them into two major groups; arc welding-based AM like Cold Metal Transfer (CMT), Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Plasma Arc Welding (PAW), and high-energy density welding based AM like Laser Beam Welding (LBW) and Electron Beam Welding (EBW). The prior study findings of welding-based AM metal components on mechanical characteristics and microstructural characterization have been addressed. This work will aid researchers, academicians, and professional welders since it gathers vital information on welding-based AM processes. Furthermore, current research in the arena of welding-based AM and its future opportunities has been discussed.

High-temperature wettability in hard materials: Comparison of systems with different binder/carbide phases and evaluation of C addition

Metal-ceramic wettability is a decisive parameter in the high-temperature sintering of hard materials. Wettability tests enable the study of this property with minimum material waste, especially useful in the search of alternative systems to WC-Co hardmetals. In this investigation, Fe-based binders – FeNiCr and FeCrAl – were tested on Ti(C,N) and WC substrates, aiming to assess: the high-temperature interactions, the dissolutive character of the liquid phase and the nature of the interphases generated, and the influence on sintering behaviour. As a result, FeNiCr led to excellent wetting scenarios for both ceramics, whereas FeCrAl alloys induced the formation of aluminium oxides. The effect of C addition on wettability was also evaluated, resulting in an improvement of this property by the inclusion of this element in the binder phase. Inspection of the microstructures resultant from powder metallurgy processing of the different configurations confirmed their excellent correlation with wettability results. As a consequence, the effectivity of this technique as a model of the sintering scenario could be asserted.

A self-powered PVA-based flexible humidity sensor with humidity-related voltage output for multifunctional applications

In the context of the industry that supports green energy and electronics, the development of a humidity sensor with self-powered characteristics and the ability to be worn by humans is crucial for expanding its practical applications. Here, we report a self-powered flexible humidity sensor based on a sandwich structure of polyvinyl alcohol (PVA)/nanocarbon powder (NCP)/magnesium chloride (MgCl2) moisture-sensitive composite film (PCMF) and Cu and Al conductive adhesive tape. This unique sandwich structure allows it to readily adsorb and diffuse water molecules in humid environments, greatly enhancing its responsiveness to humidity changes. The Cu/PCMF/Al sensor generates voltage corresponding to different relative humidity (RH) levels and has a unique RH-Voltage linear response characteristic (R2 = 0.9978), notable for its fast response/recovery (6/11 s), wide detection range (RH 11%−98%), long-term stability (over 30 days), and high voltage (∼0.6 V) and current (∼2.3 µA) output at RH 98%. More importantly, due to the good water solubility of PVA and MgCl2 salts, the designed sensor exhibits recyclability and reusability properties (90.31% of the original response voltage value), which can significantly minimize material waste and potentially reduce manufacturing costs. In addition, this sensor can be successfully applied to domains involving human wearables, such as being integrated into a mask for monitoring human respiration, and has excellent identification capabilities even for simple coughs and pronunciations. The demonstration of non-contact humidity sensing validates the prospective application of this sensor in non-contact switching devices. This work presents a novel design idea for the development of wearable humidity sensors with low cost, simple preparation, and high responsiveness, as well as self-powered characteristics.

Investigation of bending and compression properties on PLA-brass composite using FDM

Fused Deposition Modeling (FDM) is often favored over conventional techniques as it can produce highly accurate three-dimensional models with minimal material waste. Nevertheless, in FDM, the mechanical properties of different materials used in the FDM process are of ongoing interest. Since the properties of brass alloys in the FDM process are still lacking, the present study focuses on the bending and compression properties of the FDM printed part with 15 wt% and 70 wt% of brass-reinforced polylactic acid (PLA) and various infill patterns. The specimen preparation and testing were carried out accordingly to ASTM D790 and ASTM D695, respectively. The impact of five different infill patterns and two different compositions on the bending and compression properties was also analyzed using response surface methodology. A prediction model is then developed to predict the desired bending and compression properties. Results show that the 15 wt% of brass composition specimens have better properties compared with the 70 wt% of brass composition. This is due to an increase in the wt% of brass composition, which resulted in lower interlayer adhesion energy with the PLA. It was also found that the concentric and grid pattern are the best printing pattern for bending and compression properties, respectively.

Evaluasi Sisa Material Pada Pembangunan Gedung Kantor Kejaksaan Tinggi Jambi

In the Jambi High Prosecutor's Office Building Construction Project, remnants of project materials were found. Waste material is one of the serious problems in the implementation of construction projects. Therefore, it is necessary to do a careful and precise calculation in determining the amount of material needed to be used in the project as well as an evaluation of the use of these materials. The aim of this research is; calculate the largest percentage of material waste costs during project implementation, identify the causes of material waste, and find ways to minimize material waste after conducting analysis and evaluation. The method used is a sociological juridical type, which is a type or type of research that emphasizes field research. To obtain data in the field by conducting interviews with the project supervisory consultant and data on images and photos of the project. The result of the observation of processed data is that the largest percentage of residual material costs is obtained from the concrete coral material with the highest percentage of 26.553% of the total cost of the remaining material. As for the causes of material remnants on the job, the first is coming from the factor of throwing or throwing material, workers in the field often throw material such as when casting columns and beams where a lot of concrete is wasted out of the formwork, another cause occurs in the skill factor Based on the skills of workers, there are some remnants of boards from making formwork on columns and beams. And also when cutting iron, a lot of iron can't be reused because the rest of the iron that is cut is too small. The conclusion is that there is residual material in this project from the factor of throwing or throwing material carried out by workers and on the skill factor of the worker.

Optimization of Printing Parameters to Maximize the Mechanical Properties of 3D-Printed PETG-Based Parts.

Fused filament fabrication (FFF) is the most popular additive manufacturing method, which allows the production of highly complex three-dimensional parts with minimal material waste. On the other hand, polyethylene terephthalate glycol (PETG) has been used to replace traditional polymers for 3D printing due to its chemical resistance and mechanical performance, among other benefits. However, when fibres are added, these PETG-based composites can be suitable for many different applications. Nevertheless, to guarantee their good performance in-service in these applications, and even extend to new ones, it is necessary for their mechanical properties to be maximized. Therefore, this study intends to optimize the printing parameters (nozzle temperature, printing speed, layer height and filling) in order to maximize the mechanical properties of printed PETG, PETG+CF (carbon fibre-reinforced PETG composites) and PETG+KF (aramid fibre-reinforced PETG composites). The Taguchi method was used for the experimental procedure design, and the specimens were produced according to the L16 orthogonal array. Finally, an analysis of variance (ANOVA) was performed, with a 95% confidence interval, to analyse the effect of the printing parameters on the bending properties. It was possible to conclude that the best bending properties for PETG, PETG+CF and PETG+KF were obtained for extrusion temperatures of 265 °C, 195 °C and 265 °C, printing speeds of 20, 60 and 20 mm/s, layer heights of 0.4, 0.53 and 0.35 mm and an infill density of 100% for the three materials, respectively.

Gelatin methacryloyl-alginate core-shell microcapsules as efficient delivery platforms for prevascularized microtissues in endodontic regeneration

Combined injectable cell-laden microspheres and angiogenesis approaches are promising for functional vascularized endodontic regeneration. However, advanced microsphere designs and production techniques that benefit practical applications are rarely developed. Herein, gelatin methacryloyl (GelMA)-alginate core-shell microcapsules were fabricated to co-encapsulate human dental pulp stem cells (hDPSCs) and human umbilical vein endothelial cells (HUVECs) based on a coaxial electrostatic microdroplet technique. This technique enables high-throughput production, convenient collection, and minimal material waste. The average diameter of core-shell microcapsules was ∼359 µm, and that of GelMA cores was ∼278 µm. There were higher proliferation rates for hDPSCs and HUVECs co-encapsulated in the GelMA cores than for hDPSCs or HUVECs monoculture group. HUVECs assembled to form 3D capillary-like networks in co-culture microcapsules. Moreover, HUVECs promoted the osteo/odontogenic differentiation of hDPSCs in microcapsules. After 14 days of cultivation, prevascularized microtissues formed in microcapsules that contained abundant deposited extracellular matrix (ECM); no microcapsule aggregation occurred. In vivo studies confirmed that better microvessel formation and pulp-like tissue regeneration occurred in the co-culture group than in hDPSCs group. Thus, an effective platform for prevascularization microtissue preparation was proposed and showed great promise in endodontic regeneration and tissue engineering applications. Statement of significanceCell-laden microspheres combined with the proangiogenesis approach are promising in endodontic regeneration. We proposed GelMA-alginate core-shell microcapsules generated via the coaxial electrostatic microdroplet (CEM) method, which utilizes a double-lumen needle to allow for core-shell structures to form. The microcapsules were used for co-culturing hDPSCs and HUVECs to harvest large amounts of prevascularized microtissues, which further showed improved vascularization and pulp-like tissue regeneration in vivo. This CEM method and the microcapsule system have advantages of high-throughput generation, convenient collection, and avoid aggregation during long-term culturing. We proposed a high-effective platform for mass production of prevascularized microtissues, which exhibit great promise in the clinical transformation of endodontic regeneration and other applications in regenerative medicine.

Get Us PPE: A Self-Organizing Platform Ecosystem for Supply Chain Optimization during COVID-19

The COVID-19 pandemic caused a global health emergency that triggered an acute shortage of Personal Protective Equipment (PPE), putting essential healthcare workers at risk. Starting March 2020, given the skyrocketing prices of PPE in the open market, healthcare institutions were confronted with the dire need to reshape their PPE procurement strategy. One avenue that financially constrained healthcare institutions pursued were donation platforms that offered access to donated PPE by individuals and organizations. We document a real-life case study of one of the most prominent donor platforms that emerged during this period: Get Us PPE. From 20 March 2020 to 2 July 2021, Get Us PPE received 23,001 total individual requests for PPE from every US state and some US territories. In response to these 23,001 requests, Get Us PPE delivered 17,540,571 units of PPE. The number of PPE units delivered was still less than 25% of the total units of PPE requested, indicating the enormity of the PPE shortage. Using this case study, we identify key supply chain issues that manifest during emergencies and highlight the formation of a platform ecosystem to resolve these issues. We also observed a robust supply chain network design that addresses key supply chain sustainability metrics such as minimizing material waste and transportation miles, while balancing other stakeholder factors such as donor and recipient characteristics as well as shipment complexity. We argue that the roadmap followed by Get Us PPE could serve as a template for organizations that emerge in the context of future humanitarian crises.

Hybrid-3D printing of symmetric solid oxide cells by inkjet printing and robocasting

When processed using state-of-the-art techniques, Solid Oxide Cells (SOCs) fabrication (e.g. tape casting) requires many steps. Recently, Additive Manufacturing (AM) techniques have gained popularity to complement or substitute SOCs fabrication processes. AM allows the combination of different techniques to produce complete cells, minimizing material waste while reducing the number of fabrication steps and improving their reliability. 3D printed symmetrical cells with composition LSM-YSZ/YSZ/LSM-YSZ were prepared by a robocasting and inkjet printing hybrid technology, followed by a co-sintering step. Printability tests and rheological characterization have been made on the robocast LSM-YSZ slurries for the electrodes and on the water-based YSZ ink for inkjet printing to produce the dense electrolyte. This study presents the fabrication of complete cells with self-standing robocast electrodes combined with inkjet printed electrolytes and their co-sintering in one step. After co-sintering, the symmetrical cells were characterized by SEM-EDX, XRD and EIS. The microstructural analysis confirmed the feasibility of the process and its reproducibility. The electrochemical characterization led to an ASR value of ≈ 2.1 Ω cm2 at 750 °C. These remarkable results demonstrate the potential of robocasting and inkjet printing for the fabrication of multi-material energy devices.

Investigations Regarding Concrete Mixes Suitable for 3D Printing

Abstract 3D printed concrete is a relatively new technology that has been gaining popularity in the construction industry in recent years. It involves the use of a 3D printer to deposit layers of concrete in a pre-determined pattern, gradually building up a three-dimensional structure. This process offers several benefits over traditional concrete construction methods, such as the ability to create complex geometries and reduce material waste. One of the main advantages of 3D printed concrete is its ability to produce highly customized and unique designs that would be difficult or impossible to achieve using traditional construction techniques. Additionally, the precision of the 3D printing process allows for greater control over the properties of the concrete, such as its strength and porosity, which can be tailored to suit the specific requirements of the project. Another benefit of 3D printed concrete is its potential for sustainability. By minimizing material waste and using eco-friendly materials, this technology has the potential to reduce the environmental impact of construction.

Flexible Inkjet-Printed Heaters Utilizing Graphene-Based Inks.

Thermal sensors are mainly based on the selective heating of specific areas, which in most cases is a critical feature for both the operation and the performance of the thermal device. In this work, we evaluate the thermoelectrical response of two graphitic materials, namely (a) a commercial 2.4%wt graphene–ethyl cellulose dispersion in cycloxehanone and terpineol (G) and (b) a custom functionalized reduced graphene oxide (f-rGO) ink in the range of −40 to 100 °C. Both inks were printed on a flexible polyimide substrate and the Thermal Coefficients of Resistance (TCR) were extracted as TCRG = −1.05 × 10−3 °C−1 (R2 = 0.9938) and TCRf-rGO = −3.86 × 10−3 °C−1 (R2 = 0.9967). Afterward, the inkjet-printed devices were evaluated as microheaters, in order to exploit their advantage for cost-effective production with minimal material waste. f-rGO and G printed heaters reached a maximum temperature of 97.5 °C at 242 mW and 89.9 °C at 314 mW, respectively, applied by a constant current source and monitored by an infrared camera. Repeatability experiments were conducted, highlighting the high robustness in long-term use. The power–temperature behavior was extracted by self-heating experiments to demonstrate the ability of the devices to serve as heaters. Both static and dynamic evaluation were performed in order to study the device behaviors and extract the corresponding parameters. After all the experimental processes, the resistance of the samples was again evaluated and found to differ less than 13% from the initial value. In this work, fabrication via inkjet printing and demonstration of efficient and stable microheaters utilizing a custom ink (f-rGO) and a commercial graphene ink are presented. This approach is suitable for fabricating selectively heated geometries on non-planar substrate with high repeatability and endurance in heat cycles.
