Published: August 2024

Aotearoa New Zealand is changing. The relationship between the inequities iwi Māori face and centuries of colonisation is clear. The need to address these inequities and the embedded colonial thinking that reinforces them in our society is more widely accepted. Nowhere is this need for change more acute than in education. The challenge of embedding bicultural principles into all aspects of education is a significant step in decolonising education. The practice of learning design and the design of frameworks that guide education rarely have a clear process to support a bicultural approach. This case study uses participant narratives to describe the development and delivery of a workshop to establish how bicultural principles will be embedded into the design of a sustainability strategic framework within an Aotearoa higher education context. This process can provide a starting point for a range of design processes to integrate bicultural principles more readily, thus supporting the decolonisation of education in Aotearoa.

Authors: Wu Wenting , Lee Pooi See
Published: August 2024

Flexible and stretchable electrochromic displays (ECDs) perform a crucial function in Internet of Things (IoT) systems, as they have shown superior eye-friendly, energy-saving, mechanical (flexibility and stretchability) properties. They can be integrated with IoT devices and successfully applied as wearable and intelligent electronics. Flexible and stretchable ECD technology has shown promising potential but is still in the early stage of development. A systematic overview from comprehensive perspectives of materials selection and modification, structure design, and advanced fabrication methods of this technology is necessary. In this review, we concentrate on the strategies in substrates, active layers, and electrolyte aspects to fabricate high-performance flexible and stretchable ECDs. We have systematically summarized the materials selection/modification and device structure design in these strategies. We also outline recent advances in flexible and stretchable ECDs based on processing methods for electrode patterns, active layer patterns, electrolyte patterns, and ECD pixels. Moreover, the interactive visual displays integrating ECD pixels with different sensors have been elaborated. Finally, we outline the future directions for developing flexible and stretchable ECDs, focusing on materials, methods, and applications. These prospects aim to overcome the limitations in pattern resolution, electrolyte uniformity, and pixel size/number and realize the manufacturable, commercialized, scalable, and robust flexible ECDs. This review can further promote the basic research and advanced fabrication of flexible ECDs and facilitate the advancement of multifunctional displays to satisfy the increasing demand for next-generation flexible electronics.

In the context of Russia’s special military operation in Ukraine, the situation around Transnistria has significantly worsened. The Ukrainian side does not abandon its clear intentions to involve Chisinau in the escalation of the conflict with the PMR. Actions of this kind can provoke a destabilization of the situation in the region. The United States and NATO are increasing their pressure on Chisinau, hoping to use Moldova both in a local operation to defeat and capture Transnistria, and in the general anti-Russian bloc.

Published: August 2024

Russian-Georgian relations throughout the post-Soviet period experienced stages of confrontation and normalization. After the 2008 war, political contacts were virtually frozen. Over the past few years, the country’s government has demonstrated a consistent pragmatic position aimed at normalizing bilateral relations. Data 2022–2023 show growth in the trade, economic and tourism sectors. However, as sociological surveys show, a fairly large percentage of Georgian citizens express dissatisfaction with the political course of the ruling Georgian Dream party. Against the backdrop of the upcoming parliamentary elections, most of the government’s steps are perceived by part of society as “pro-Russian”. On the other hand, among part of society there is still a high demand for normalization of relations between Russia and Georgia.

Synthesis of Multicopter Stabilizing Control
Authors: Gu Penghao , Lobaty A. A.
Published: August 2024

The paper is devoted to the problem of analytical synthesis of control that stabilizes the position in space of an unmanned aerial vehicle (UAV) of a multi-rotor type a multicopter. An analysis of UAVs of this class has been carried out, features, place and differences among UAVs of various design schemes have been determined. The type of spatial mathematical model describing the translational and rotational motion of a multicopter is substantiated, which is considered to be  a model of a four-rotor UAV – a quadrocopter, since such UAVs are widespread and have the basic properties that are inherent in such aircraft devices. A transition was made to a linear simplified model of UAV movement by linearization and justification of the main assumptions made during the linearization of the mathematical model. The problem of determining stabilizing control is reduced to the classical form of analytical synthesis of control that minimizes a given integral quality functional. A feature of the considered quality functional is the justification of normalization coefficients, which make it possible to reduce the summable integrands of various physical natures to a dimensionless form and take into account the real  restrictions imposed by the technological and design features of a particular UAV on its maneuvering characteristics.  As a result of the analytical solution of the problem, expressions for optimal control have been obtained, which are changes  in time in the rotation speeds of the opposite quadcopter propellers, allowing to stabilize the position of the UAV in space, compensating for external undesirable effects on the UAV in the form of gusts of air flow or other factors. The executed computer simulation has confirmed the efficiency of the developed methodology. The given graphical dependences of the change in time of variables characterizing the control action and movement of the UAV in space clearly show the type of transient processes and allow us to evaluate the maneuver-ring capabilities of the UAV and formulate the basic requirements for its structural elements at the preliminary design stage.
Research of the Influence of the Scheme and Modes of Pressing Steel and Cast Iron Chips on the Energy-Power Parameters of the Briquetting Process
Authors: Dyakonov O. M. , Litvinko A. A.
Published: August 2024

The paper presents the results of an experimental study of the process of hot briquetting of fine-grained ferrous metal waste in a mold with a movable matrix. It has been established that in order to achieve the required density of finished briquettes of 90–95 % (one of the main quality criteria for modern metallurgical production), in the temperature range of hea-ting the charge of 700–850 °C, the pressing pressure reaches values of 470–500 MPa. The use of molds with a movable matrix ensures reduction in pressure and pressing force of ductile low- and medium-carbon steels up to 45 %, high-carbon, low ductility and difficult to deform - up to 35 %, cast iron – up to 25 %. The specific work of deformation (energy costs) when hea-ting waste ferrous metals to temperatures of incomplete hot deformation is reduced by 2.3–2.5 times. Compared to briquetting in a fixed matrix at the same temperatures, the specific work of deformation is reduced by 15–20 %. The process of deformation compaction of a discrete porous body occurs with minimal impact of lateral contact friction forces, since the compaction front (compacted chip layer) moves together with the matrix in the same direction with minimal relative displacement of the friction surfaces. The nature of deformation compaction and the level of resistance to deformation depend on the initial state of the material: the higher the plasticity of the metal, the more intense the compaction density increases; the higher the initial density and yield strength, the greater the pressing pressure must be applied to achieve the same density value. Fine additives of metallic or non-metallic origin fill the voids between larger fractions of chips and thus increase the initial compaction density and the pressure gradient as density increases.

Authors: Samuilov Yu. D. , Batyanovsky E. I.
Published: August 2024

The material in the paper reflects the main stages and results of the development of low-energy-intensive technology for producing cellular aerated concrete without autoclave hardening using a micro-filler based on granite screenings for prefabricated and monolithic construction, including its application in 3D concreting technology [1–10]. The paper has made it possible to develop and experimentally to substantiate: methods for calculating the composition of aerated concrete according to the criteria of density and compressive strength in the range of grades D350–D900 and classes B0.5–B7.5 for structural and thermal insulation purposes, as well as grades D100–D300 (compressive strength 0.04–1.5 MPa) for thermal insulation purposes in conjunction with the dispersion of the applied micro-fillers from ground granite screening with a specific surface area, respectively: Ssp ~ 3000–500 cm2/g for structural and thermal insulation, and for thermal insulation aerated concrete: Ssp ~ 30000 cm2/g (micro-silica) and Ssp ~ 20000 cm2/g (ultra-disperse fractions of granite screenings) – for thermal insulating aerated concrete; methodology for monitoring the rheological (technological) properties of aerated concrete mixtures that provide the required conditions for the structure formation of aerated concrete of calculated compositions, a method for evaluating the lateral pressure of a mixture when laying in formwork (molds), as well as a method and device for non-destructive testing of both the kinetics of strength growth of hardening and the strength of hardened or used cellular concrete, obtained according to the developed or other technology. Modes of non-heating and low-energy (including steaming at  atmospheric pressure) technology of cellular aerated concrete of non-autoclave hardening have been developed, which makes it possible to abandon energy-consuming, technically complex and expensive autoclave equipment in the manufacture of prefabricated products and provides the possibility of using the developed technology of thermal insulating aerated concrete  in monolithic construction, including heat and sound insulation of the walls of buildings made using 3D concreting technology, as well as the construction (installation) in removable and non-removable formwork of building structures using aerated concrete for structural and thermal insulation purposes.
Normalization оf Fine Aggregate Granulometry fоr Struсturаl Соnсrete
Authors: Fedаrоviсh P. L.
Published: August 2024

It must be noted that the construction industry of the Republic of Belarus is forced to use fine aggregate for low-quality concrete due to the lack of high-quality natural sand in many regions of the country. When using this aggregate in the preparation of concrete mixtures and mortars, an increase in cement consumption is required to confirm the quality of the concrete. The research results of this work can be used to improve the quality of fine aggregate when used in concrete. The technology for producing normalized (enriched) sand of the required granulometry has theoretically and experimentally proven itself positively due to the introduction into natural (fine, medium) sand of fractions of granite screenings ≥(0.5–0.6) mm in size, formed at the RUPP “Granit” of the Brest region Belarus in the production of coarse aggregate for concrete. A computer program “Normalization” (registration number 022 dated 03/07/2024) has been developed to calculate the required ratio of the starting material – natural sand (characterized by a fineness modulus: 0.9 < Mk < 2.5) and processed (prepared) granite screenings of size ≥(0.5–0.6) mm to ensure the required granulometry of enriched sand with Mk = 3.25–3.50. All conditions have been identified for obtaining a material of any granulometric composition, characterized (if there is such a need) by a particle size modulus within the limits recommended by the current technical regulatory legal acts (TNPA): 2.0 < Mk < 3.5. The effectiveness of the technology for normalizing the granulometry of fine-grained natural sands has been experimentally confirmed and is determined by an increase in concrete compressive strength up to 25–40 %, axial tensile and shear strength up to 35–45 %, a decrease in the delamination rate (solution separation and water separation) by 30–47 %, as well as increasing the elastic-deformation characteristics and operational properties (waterproofing, water, salt and frost resistance) and the protective ability of concrete in relation to steel reinforcement, with an assessment of the degree of its corrosion damage. Industrial testing has confirmed the possibility of reducing the cement content in concrete by 10–20 % without deteriorating its physical and mechanical properties. Based on the totality of research results, it was determined that the method of enriching natural sand with large fractions of granite screenings can be used for concrete for various purposes without restrictions.

Growing concerns about the employability of science graduates has led most Australian higher education providers to incorporate work-integrated learning (WIL) into their science curricula. Project-based learning (PjBL) is a student-centred approach to learning that focuses on the application of discipline specific skills and knowledge in real-world contexts. While a large body of research exists exploring PjBL frameworks and theories related to student experience, research into industry perspectives and viewpoints is limited. This study aimed to determine the views of industry professionals on PjBL as a form of WIL, and to ascertain whether industry professionals consider PjBL effective for the development of desirable graduate skills. The perspectives of industry partners were canvased through a mixed-methods approach comprising surveys and interviews. Participants (n=18) were asked to indicate their opinions regarding development of graduate skills through PjBL generally and in relation to two authentic examples of PjBL in WIL. The results of this study indicate that industry partners preferred longer-term, workplace-integrated industry projects for developing graduate skills and preparing graduates for the workforce. Industry partners interviewed generally exhibited positive views of PjBL, identifying students’ attitudes and communication skills as beneficial factors. Some industry partners indicated current graduate programs where insufficient in preparing students for employment. These results highlight the importance workplace integration in successful implementation of PjBL as a form of WIL, and the need for stronger collaboration between employers and academia to correct the current misalignment between graduate skills and industry requirements.

Published: August 2024

Background
Taking into account what has been reported by numerous authors over the past decades regarding the causal relationship between Space Weather and solar eruptive activity and the Biosphere in general, it is of scientific and practical interest to delve into the connections that have shown some relationship, aiming to counteract the negative effects and leverage the potential benefits of using such knowledge for the benefit of humankind. Such is the case of agricultural performance, where in recent years its relationship and synchronization with the multi-year cycles of solar activity have been identified. The eleven-year cycles (11 ± 1 years) of solar activity, recorded since 1700, have been forecasted with considerable precision in recent decades concerning the occurrence of minimums and maximums. This allows for anticipation, with corresponding error, of the years expected to witness increases or decreases in agricultural productivity for numerous crops demonstrating the mentioned synchronization. This insight could lead to better resource planning in the short and medium term, aiming to achieve a more favorable cost-benefit ratio and profitability in the agri-food industry, which constitutes the objective of this type of research.
Methodology:
The Fast Fourier Transform (FFT) and tools from Microcal Origin 6.0 were employed.
Results
The results of the analysis of time series data on the yield of 10 economically important agricultural products in Germany concerning solar activity cycles are presented. These were graphically analyzed using cross-correlation and their spectra.
Conclusion
The obtained result supports the hypothesis of a temporal association between the studied phenomena.

A cow’s lifetime productivity is influenced not only by breed and age at first calving, but also by feeding conditions and appropriate supplementation. The objective of the study was to determine the effect of two different lick supplementation strategies between weaning and first conception on the calving percentage and weight over the first three calving seasons. In the study, 24 Bonsmara heifers were divided into two groups of 12 animals each after weaning. The two heifer groups received the same mineral lick during summer. During winter months (April – September), the one group received a protein rich winter lick (400g/kg protein) while the second group received a production lick (winter lick supplemented with yellow maize in a ratio of 2:1). The heifers were bred naturally at 24 months during a three-month summer breeding season (December – February). Calving percentage and reconception rate of the group which received production lick in the winter was 92%, 50% and 58% for the first, second and third calving seasons. This was significantly higher than the calving percentage of 67%, 42% and 33% for the group which received only winter lick. Cow weight at calving and calf 205 day corrected weaning weight were higher over the three consecutive calving seasons for the heifers receiving production lick during winter. These results indicate that it may be worthwhile to provide good supplementation before the first breeding season for the incentive of a better calving percentage and higher calf weaning weights up to the third calving season.
Sulfo-Phospho-Vanillin-based screening for identification of Aurantiochytrium strains with elevated DHA levels

Published: August 2024

Aurantiochytrium are protists found in marine and estuarine environments, known for producing high quantities of omega-3 fatty acids, particularly docosahexaenoic acid (DHA). The commercial viability of this species is currently hindered by the lack of reliable screening methods for the rapid identification of strains with high DHA content. This study developed a high-throughput screening platform based on the Sulfo-Phospho-Vanillin (SPV) reaction, which produces a pink chromophore upon reacting with C-C double bonds in lipids. Analysis of 200 strains derived through the UV mutagenesis of the Aurantiochytrium limacinumstrain BL10 revealed 7 strains that exhibited significantly elevated SPV reactivity, compared to the naïve strain. In subsequent GC-MS analysis, 4 of the 7 strains exhibited DHA levels that were significantly higher than those of the naïve strain. The proposed SPV reaction protocol shows considerable potential for the high-throughput screening of Aurantiochytrium strains with high DHA content, whether isolated from nature or derived via mutagenesis.

The cuticle is a polymeric membrane covering all plant aerial organs of primary origin. It regulates water loss and defends against environmental stressors and pathogens. Despite its significance, understanding the micro-mechanical properties of the cuticle (cuticular membrane; CM) remains limited. In this study, non-invasive Brillouin light scattering (BLS) spectroscopy was applied to probe the micro-mechanics of native CM, dewaxed CM (DCM), and isolated cutin matrix (CU) of mature apple fruit. The Brillouin frequency shift (BFS) decreased significantly with wax extraction from the CM and further decreased with polysaccharide extraction from the DCM, consistent with tensile test results. Spatial heterogeneity was observed by BLS microscopy of the CM, with BFS of the anticlinal region being significantly smaller than that of the periclinal region. In the DCM, BFS was higher in the periclinal than in the anticlinal region, while in the CU, BFS was similar in both regions. The key conclusions are: (1) BLS is sensitive to micro-mechanical variations, particularly stiffness, offering novel insights into the CM’s micro-mechanical behavior and underlying chemical structures; (2) CM exhibits spatial micro-mechanical inhomogeneity, with periclinal regions being stiffer than anticlinal regions, likely due to the heterogeneous distribution of wax and polysaccharides.

The evolution of body weight under the natural trypanosome challenge and its association with disease tolerance to trypanosomosis is of utmost economic importance in cattle. This study estimated heritability for growth traits and packed cell volume (PCV) and their genetic correlations in the N’Dama cattle in the Gambia. A total of 2,488, 2,442, 1,471, 1,934, and 1,452 bodyweight records at 12 months (WT12), 16 months (WT16), 18 months (WT18), 24 months (WT24), 36 months (WT36) and 50 months (WT50) and 1,782, 1,800, 1,844, 1,608, and 1,459 records for PCV at 12 months (PCV12) 18 months (PCV18), 24 months (PCV24), 36 months (PCV36), and 50 months (PCV50), respectively, were analysed. Genetic parameters were estimated using univariate and multivariate animal models using the GIBBSF90 software. Least square means for WT12, WT18, WT24, WT36 and WT50 were 75.08±0.37kg, 95.58±0.52, 123.80±0.52kg, 149.90±0.73kg and 190.37±0.68kg, respectively. The Least square means for PCV declined from 24.56±0.18 at 12 months of age to 23.18±0.19 at 50 months. Heritability estimates for growth ranged from 0.47±0.05 at 12 months to 0.31±0.06 at 50 months, while for PCV the estimates were 0.09±0.01 to 0.15±0.01. Genetic correlations between bodyweights were high and positive (0.73±0.01 to 0.96±0.01) while those between PCV traits were low to medium and positive (0.16±0.04 to 0.56±0.02). Genetic correlations between bodyweight and PCV range from -0.14±0.02 to 0.59±0.02. BW18 and PCV18 had high heritability estimates and as well as the highest genetic correlation and therefore could be used as selection criteria for body weight and trypanotolerance, respectively.
