Published: November 2023

After the industrial revolution, our world started shifting its focus towards sustainability and eco-friendly green materials to replace their synthetic counterparts. Cellulose fibers have played a significant role in human history, providing clothing and various products for many centuries. However, as technology advanced, the use of natural fibers became limited and minimized by synthetic materials. Growing environmental awareness has compelled industries to rethink their strategies, directing their attention toward sustainable and eco-friendly alternatives. In this context, natural cellulose fibers have gained a significant interest due to their eco-friendliness. These fibers can be derived from various sources, including trees, plants, and grasses. Cellulose fibers obtained from plants possess remarkable properties such as low density, wide availability, considerable mechanical strength, good thermal insulation, affordability, ease of processing, and non-toxicity

Published: November 2023

The current study reviews provide a brief overview on the properties of natural fiber and natural fiber reinforced composites like chemical, physical, mechanical properties and thermal behavior which is an emerging area in polymer science. The unique properties of these composites are based on the attributes of the individual components, as well as the relative numbers and arrangements of those components within the material system. The widespread acceptance of composites reinforced with natural fibers has attracted many researchers due to its cost, sustainability, low environmental impact and great availability in nature. The processing of natural fibers is not difficult as compared to the production of conventional fibers. In the construction, aerospace, military, building, packaging, consumer products, and transportation industries for ceiling, paneling, partition boards, etc., natural fibers have shown to be a successful substitute for synthetic fiber. Because of these factors, natural fibers are preferred to conventional fibers. However, natural fiber reinforced composites also have some negative aspects such as increased susceptibility to water damage, less durability in the event of a fire, and diminished strength when they are subjected to mechanical stress. In this paper, the overview related to the natural fiber-reinforced composites and their properties is provided.

Published: November 2023

The multi-extruder printer allows to printing of different materials into one product. This paper experimented on multi-material lamination using PLA with rigid characteristics and Carbon-PLA with elastic characteristics. The flexural and shore hardness test was chosen to understand how two different materials affect each other. The results show that the different lamination performances affect the flexural strength. The highest flexural strength from 3 laminations was the CPC of 53.33 MPa, this is 3.03% lower than the PLA only and 37.9% higher than Carbon-PLA only. From the 2 laminate specimens the PC laminates achieved the highest flexural strength of 73.07 MPa, the value is 5.4% higher than the PLA only and 50.01% higher than Carbon-PLA only. The shore hardness value showed no significant changes between the lamination and 1 material only. It was also proved that lamination formation can increase the flexural strength or lead to detrimental results. This finding enables the designer of multi-material 3D printing to consider the formation of materials.

Published: November 2023

This study aims to find the optimal nanofibrillated cellulose (NFC) concentration isolated from oil palm empty fruit bunch (OPEFB) particles to form stable pickering emulsions against creaming and coalescence. The emulsification process is based on a combination of homogenizer and ultrasonication. Pickering emulsion was prepared by mixing the dispersed phase (palm oil) and the dispersing phase (NFC concentration of 0.05 - 0.7 w/v%) at the ratio of 10:90. Fresh emulsion has a milky white appearance and is homogeneous. However, some samples' creaming process occurred on the 30th day of storage. Microscopic observations show that the droplets are round with various sizes. Differences in NFC concentrations significantly affect droplet size, zeta potential, rheology, and emulsion stability. Increasing the NCF concentration resulted in smaller droplet sizes, viscosity, zeta potential, and pickering emulsion stability. The emulsion has high stability against coalescence and creaming. NFC at 0.7 w/v% generates an emulsion with the best characteristics and high stability against creaming and coalescence. OPEFB-based NFC has the potential as a pickering emulsion stabilizer particle that can be applied to the food and non-food industries.

Published: November 2023

Werden Störungen in Wäldern auf der Alpennordseite in den nächsten Jahrzehnten zunehmen? Auf der Suche nach Antworten liefern quantitative Angaben über Waldschäden wie Sturmholz, Käferholz, Bruchholz und Waldbrandflächen vom Beginn des 20. Jahrhunderts bis heute konkrete Anhaltspunkte. Trotz Unvollständigkeit der Datenreihen zeigen die meisten Trends eine starke Zunahme der Waldschäden infolge von Störungen seit den 1980er-Jahren an. Gründe dafür sind der verschärfte Klimawandel, steigender Holzvorrat, invasive Schadorganismen und verschiedene Interaktionen. Wir gehen davon aus, dass diese Trends sich in gleicher Richtung fortsetzen werden.
Zwischen Sturmwurf und Borkenkäferbefall: Management von Extremereignissen in Südtirol
Authors: Wellstein Camilla , Broll Mario , Unterthiner Günther , Pietrogiovanna Marco
Published: November 2023

Die Sturmnacht Vaia vom 29. Oktober 2018 hinterliess schwere Windwurfschäden in Südtirols Wäldern. Eine schnelle Strategiefindung und die relative Grösse der Schadensflächen ermöglichten ein effizientes Aufräumen des Totholzes über einen Zeitraum von zwei Jahren, unterstützt durch eine Förderung der Arbeiten durch Prämien. Die Ergebnisse des Borkenkäfermonitorings zeigten, dass nach dem Sturmwurf keine besorgniserregenden Populationsentwicklungen des Buchruckers festgestellt wurden. In den Folgewintern ergaben sich Schneedruckschäden, welche viel kleinräumiger und diffuser verteilt waren und daher nicht effektiv geräumt werden konnten. Die Borkenkäferflächen, welche sich seit 2020 zunehmend entwickelten, sind wie die Schneedruckschäden ebenfalls kleinräumig und diffus verteilt und schwierig für die Bringung. Trotz Prämien und Intensivierung der Bringung konnten befallene Bäume nicht ausreichend entfernt werden. Die Entwicklung der Borkenkäfer ist von der Witterung beeinflusst, welche für die Käfer 2021 zwar ungünstig, in 2022 jedoch günstig war. Im Jahr 2023 hat ein relativ kühles und nasses Frühjahr den Ausflug der Käfer eingebremst. Während dank der traditionellen Forstgärten genügend standorttypische Pflanzen für eine Aufforstung verfügbar sind, ist der Wildverbiss sowohl bei der Naturverjüngung als auch bei der Aufforstung ein grosses Problem. Beim Management der genannten Extremereignisse liefen je nach Ausmass und zeitlicher Manifestation des Schadens unterschiedliche Stakeholder-Prozesse ab. Meteorologisch gesehen könnten sich ähnliche Extremereignisse wiederholen, weshalb eine Nutzung der Erkenntnisse und der Erwerb angepasster oder neuer best practices inklusive Stakeholder-Prozesse sehr sinnvoll für einen nachhaltigeren Umgang mit Klimaschäden erscheint.
Strategien zur Klimaanpassung im Wald - von der Schadensbewältigung zur Vorsorge

Published: November 2023

Ein europäischer Ländervergleich zeigt, dass statt der traditionellen Schadensbewältigung neue, proaktive Ansätze für einen resilienten und resistenten Wald nötig sind. Die Förderprogramme zur Bewältigung von Extremereignissen in den beiden Schweizer Kantonen Bern und Aargau entwickeln sich ebenfalls in diese Richtung. Die Akzeptanz verschiedener Ansätze der Klimawandelanpassung im Wald wurde mit einer Befragung untersucht. Viele Waldbesitzer und -bewirtschafter gehen reaktiv vor und setzen auf einheimische Baumarten. Ein stärker proaktives Vorgehen auf gefährdeten Waldflächen, auch unter Berücksichtigung von Gastbaumarten, ist dennoch für einen erheblichen Teil der Befragten denkbar. Dabei spielt die Höhe der finanziellen Förderung für die meisten die entscheidende Rolle.
Infrastructure Requirements for Clear-Fell Harvesting of Small-Scale Plantation Forests in New Zealand
Authors: Allum Jacob , Harvey Campbell , Visser Rien , Hoffmann Stephan
Published: November 2023

Background: Small-scale forests (woodlots) increasingly account for a greater proportion of the total annual harvest in New Zealand. There is limited information on the extent of infrastructure required to harvest a woodlot; road density (trafficable with log trucks), landing size, or the average harvest area that each landing typically services. Methods: This study quantified woodlot infrastructure averages and evaluated influencing factors. Using publicly available aerial imagery, roads and landings were mapped for a sample of 96 woodlots distributed across the country. Factors such as total harvest area, average terrain slope, length/width ratio, boundary complexity and extraction method were recorded and investigated for correlations. Results: The average road density was 25 m/ha, landing size was 3000 m2 and each landing was serviced on average 12.8 ha. Notably, 15 of the 96 woodlots had no internal infrastructure, with the harvest completed using roads and landings located outside of the woodlot boundary. Factors influencing road density were woodlot length/width ratio, average terrain slope and boundary complexity. Landing size was influenced by average terrain slope, woodlot length/width ratio, and woodlot area. Conclusion: The results provide a contemporary benchmark of the current infrastructure requirements when harvesting a small-scale forests in New Zealand. These may be used at a high level to infer the total annual infrastructure investment in New Zealand's woodlot estate and also project infrastructure requirements over the foreseeable future.
Economic Evaluation and Performance of a Tree Planting Machine Performing in Two Different Slope Classes and Conditions of Harvesting Slash

Published: November 2023

In recent years, fully mechanized planters have gained attention in Brazil on flat to steep terrain. A field study was conducted to analyze the potential of a planting machine composed of a hydraulic crawler excavator and a planter unit to perform soil preparation and planting in two slope classes and two conditions of slash presence. The experimental area was divided according to slope – undulating (8% to 20%) and strong undulating (20% to 45%) – and the presence of slash. Slope class did not significantly affect productivity, nor was there a significant interaction effect between the slope and slash factors. The presence of slash proved to be statistically different, with mean productivity of 236 seedlings hour-1 when reloading the carousel in an area without harvesting slash. Tree planting machine utilization was 75.13%, and the mechanical availability was 79.6%. The presence of slash significantly reduced the tree planting machine productivity, including the seedling reloading time, suggesting a newer research line for fasters reloading seedling systems.
Exploring the Origin of Geoid Low and Topography High in West Antarctica: Insights from Density Anomalies and Mantle Convection Models
Authors:   GFZ German Research Centre for Geosciences, Telegrafenberg, 5 14473 Potsdam, Germany, Steinberger Bernard , Grasnick Maya-Laureen , Ludwig Ronja
Published: November 2023

The deepest geoid low globally with respect to hydrostatic equilibrium is in the Ross Sea area. Nearby in West Antarctica is a residual topography high. Both are in a region with thin lithosphere, where a mantle plume has been suggested. Hence upper mantle viscosity could be regionally reduced, allowing for faster rebound than elsewhere upon melting of the West Antarctic Ice Sheet, one of the global climate system’s tipping elements. To study possible causes of the geoid low / topography high combination, we compute the effects of disk-shaped density anomalies. With -1% density anomaly and a global average radial viscosity structure, geoid low and topography high can be explained with disk radius about 10° and depth range ~150-650 km. Alternatively, there may be two separate disks somewhat laterally displaced, one just below the lithosphere and mainly causing a dynamic topography high and one below the transition zone causing the geoid low. If viscosity in the uppermost mantle is reduced by a factor 10 (from 50 to 350 km depth) to 100 (from 100 to 220 km), one shallow disk in the depth range 50-350 km would also be sufficient. In order to test the feasibility of such density models, we perform computations of a thermal plume that enters at the base of a cartesian box corresponding to a region in the upper mantle, as well as some whole-mantle thermal plume models, with ASPECT. These plume models have typically a narrow conduit and the plume tends to only become wider as it spreads beneath the lithosphere, typically shallower than ~300 km. These results are most consistent with the shallow disk model with reduced uppermost mantle viscosity, hence providing further support for such low viscosities beneath West Antarctica.

Published: November 2023

A Sequencing Batch Reactor is a wastewater treatment plant that degrades pollutants in wastewater using microbes.. The purpose of this research is to improve the performance of a Sequencing Batch Reactor (SBR) by incorporating a sludge zone. The addition of a sludge zone in the Sequencing Batch Reactor (SBR) allows the sludge formed as a byproduct of processing waste water to be accommodated rather than eroded back into the fluid. The method employed compares SBR with and without the addition of a sludge zone. Furthermore, the hydraulic retention time (12, 24, 36, and 48 hours) and air flowrate (7 and 14 ml/minute) were investigated. According to the study's findings, the SBR with the addition of the sludge zone removed 97% COD, 79% total N, 53% total P, 85.6% TSS, and 81% fatty oil. Meanwhile, SBR without a sludge zone yielded 96% COD, 72% total N, 45% total P, 82% TSS, and 74% oil and grease.

A fuel cell is an electrochemical cell that converts chemical energy into electrical energy directly through reactions. The use of acidic polymers (chitosan) and basic polymers (PVA) aims to reduce costs, flexible design, offers easy and synergistic effect of new composite membranes, and facilitates transport mechanism through Grotthuss membranes. Factors that affect membrane fabrication in this study are variations in polymer concentration and time. In this study, the ion exchange capacity, methanol permeability, water and methanol absorption, and membrane moisture content were tested. From the test results, the resulting membrane has a lower methanol permeability value of 3.9x10-7 cm2/second than the Nafon 117 membrane which is 26.9x10-7 cm2/second, and the maximum IEC obtained is 1.07 meq./g. The polyvinyl alcohol and chitosan polyelectrolyte membranes exhibited lower dehydration characteristics compared to Nafon, which had the remarkable disadvantage of higher temperatures (above 80°C) leading to long-term conductivity of the membranes. Polyelectrolyte membranes of polyvinyl alcohol and chitosan have the lowest water content of 8.5% because of the air content trapped by polymer functional groups.

Exploring the Limitations of a Circular Economy Under Capitalism and Raising Expectations for a Sustainable Future
Authors: Deutz Pauline
Published: November 2023

The concept of a circular economy has gained remarkable policy and academic traction. Associated expectations of social benefits are underexamined. Driven by the current perilous state of the environment and society, this article pulls aside the curtain of perceived academic political neutrality that hides the implications of capitalism. Whilst a circular economy brings new options for business, places and individuals, political action is needed to bring about significant, and lasting, change. A system driven by profit does not and cannot respond to needs. It is time for a serious discussion to improve the prospects for everyone’s future.
PLURALITY OF MAIN PLACE OF WORK
Authors: Rudenok Daniil V.
Published: November 2023

The article describes what primary employment is, according to the labour law system of Russian Federation. It reveals that there is no definition of such concept and tries to derive it through the legal history. A workbook was the unique and remains one of the main characteristics of the primary employment, so the paper discusses, is it possible to combine legally two or more primary employers having more workbooks. The judicial opinion is analysed and there are shown different approaches that result from the lack of legal definition of primary employment in the Labour Code of Russian Federation. The author’s approach based on the law branch principle of combining state and contractual regulation of labor relations and on the primacy of the labour contract proves that one could have more primary employments. The type of employment is one of the terms of labour contract. Multiple primary employment is not prohibited, so the author concludes, that such employment is legal, but the main point is not regulated because of the lack of legal definition what primary employment is. This causes ill effects for the worker, because he’s not protected as well. Therefore a primary employment is without specifying that it is offtime job.

Effect of Fire on Concrete Contribution to ShearResistance of GFRP RC Beams
Authors: Mehany Mahmoud
Published: November 2023

The use of fiber-reinforced polymer (FRP) bars is becoming commonplace in various civil engineering applications due to the several advantages they offer over traditional materials. However, limited knowledge about some aspects of the behavior of FRP bars, particularly when subjected to severe fires, is hampering their widespread use. This paper presents the results of a research program to investigate the shear behavior of glass-FRP (GFRP)-reinforced beams exposed to severe fires. Three reinforced concrete (RC) beam specimens with a cross-sectional width and height of 150 mm and 300 mm, respectively, and with a total length of 1700 mm were constructed and tested under four-point bending load up to failure. The main test variables were the reinforcement ratio and the fire. The experimental results show that all beams failed as a result of diagonal tension cracking. The shear resistance and stiffness of the RC beams decreased when the beams are exposed to fire at the same reinforcement ratio. Keywords: GFRP bars, reinforced concrete beams, fire, shear capacity, crack patterns, modes of failure.

Exploring Code Samples Characteristics and Their Impacts on Software Ecosystems
Authors: Menezes Gabriel , Cafeo Bruno , Hora André
Published: November 2023

Code samples are made available to assist developers to accelerate the learning process of features provided by frameworks. However, we know little about how code samples are developed and consumed. In this paper, we aim to fill this gap by assessing the characteristics of framework code samples. We provide insights into how code samples are maintained and used by developers. We find that most code samples are small and simple, and provide a working environment. They frequently change, for example, to adapt to new framework versions. To further understand the problems faced by developers, we analyze Stack Overflow and 269 issues from code sample repositories. We find that developers face problems when modifying the code samples and the most common issue is related to improvement.
