Effects of Volcanic Tuff Use on the Rheological and Mechanical Properties of Self-Compacting Concrete
Authors: Musungu Khaoya Lewin , Abuodha Sylvester , Mwero John Nyiro 
Published: September 2024

The rise in demand of concrete products has led to overexploitation of river sand the main fine aggregate in concrete resulting in major environmental degradation. As a result, researchers have focused their efforts on developing eco-friendly concrete using alternative renewable materials like volcanic tuff and other natural pozzolana types. This study therefore, aims at investigating the use of Kenyan, Kitengela volcanic tuff as a partial replacement of river sand in self-compacting concrete, and determining the effects it will have on the rheological and mechanical properties of the self-compacting concrete. The study involved partially replacing river sand with volcanic tuff in percentages of 0%, 2.5%, 5%, 7.5% and 10% and carrying out rheological tests (V-funnel test, L-box test, T-500 test and J-ring test) on fresh concrete and mechanical tests (compressive strength and tensile strength tests) on hardened self-compacting concrete on days 7, 14, and 28 to determine the effects of volcanic tuff on properties of both fresh and hardened self-compacting concrete. There was a general decrease in rheological properties (flow and passing abilities) of self-compacting concrete with increase in volcanic tuff percentage replacement from 0 % to 10%, with least flow and passing abilities recorded at 10% replacement. Similarly, increase in volcanic tuff percentage replacement led to decrease in both compressive and tensile strength of self-compacting concrete with lowest values recorded at 10% volcanic tuff replacement.
Study on the Adaptability of the Cultivation Mode of Su Embroidery Craft Talents in the Context of Globalization
Authors: Zhang Ting 
Published: September 2024

Abstract
The export products of Su embroidery have gradually expanded from tablecloths, handkerchiefs, etc., to murals, screens, etc. The internationalized varieties are increasing, which requires a higher quality of Su embroidery craft talents. In this paper, in order to study the globalization teaching quality and the internationalization vision of the Suzhou embroidery industry in each Suzhou embroidery talent training institution, we construct the evaluation model of the globalization adaptability of Suzhou embroidery talents. After selecting the indicators at all levels, the traditional AHP method is optimized using the OWA algorithm to more reasonably allocate the weights of the indicators, and then the evaluation matrix is established for a fuzzy comprehensive evaluation. Four representative Suzhou embroidery vocational colleges in the Suzhou area have been selected to analyze the globalization adaptability of their embroidery craft training. It has been found that school W has a comprehensive evaluation score of 90.86, which is highly adaptable to the globalization of the cultivation of Suzhou embroidery talents and has excellent international competitiveness. Institutions X and Y have comprehensive evaluation scores of 84.16 and 81.34, which are a good level, but there is a big gap between them and school W in terms of the foreign exchange of the culture of the craft of Suzhou embroidery and cultivation of talents with globalization mindset. Out of the four schools, School Z has the worst comprehensive evaluation score, with only 72.2. School Z has the worst score; its understanding of the Suzhou embroidery craft going to the sea in the context of globalization is insufficient, and the quality of cultivation of graduates in Suzhou embroidery cultural exchange, product export, and other related competence literacy needs to be improved. This study provides a new perspective and feasible path for cultivating export talents of traditional cultural products, such as Su embroidery.

Published: September 2024

Abstract
In this article, we explore the enduring barriers to gender equality in the Nordic film industry, with a focus on positions of power and structural biases. Despite considerable efforts over the past decades to highlight gender inequality – resulting in more women in creative positions in Sweden, Denmark, and Finland – a significant gap remains. Our analysis of 1,070 films produced and released theatrically between 2010 and 2020 in Denmark, Finland, Iceland, Norway, and Sweden shows men dominating directing, writing, and producing roles in 75 per cent of the cases, with women slightly more present in producing. The study finds a negative correlation between the dominance of men in producing roles and the presence of women in directing and writing roles. Factors such as the size of the creative team and co-production had less impact on the proportion of women in key creative positions than expected, whereas a higher proportion of women in managerial roles is linked to an increased presence of women in positions of directing (Sweden) and writing (Finland). These results indicate that while some progress has been made, structural barriers still significantly hinder gender equality in the industry.

Published: September 2024

Abstract
Diversification of energy resources is a current objective that several countries want to achieve, including in northern Europe. Demand for wood fuels is increasing in Latvia, which is reflected in consumer expenditure. Using low-quality biomass (LQB) to produce fuel pellets for market stabilisation and diversification is possible. LQB pellets can theoretically and practically be used in low-capacity solid fuel boilers to provide different types of individual heating systems with an alternative energy source. Before starting mass production of LQB fuel pellets, it is necessary to clarify the properties of the raw materials. Any fuel study shall be divided into two phases: determination of the parameters of the fuel or raw material (calorific values, moisture content, and ash content) and analysis of the combustion process. The combustion process can be studied in two ways: experimentally and by mathematical modelling. Knowing the parameters that would need to be clarified during the study of the LQB fuel pellets combustion process (thermodynamics, gaseous emissions, particulate matter emissions, bottom ash, and slag), the authors have set the goal of clarifying the software applied to mathematical modelling of these parameters. A bibliometric analysis method was chosen to identify the software. The bibliometric analysis was carried out in the Scopus database. As a result, two software were identified: ANSYS Fluent software is suitable for modelling thermodynamic processes and gaseous emission streams. At the same time, XDEM software is the most suitable for modelling particle streams and ash/slag generation. This software will be used in future studies.

Published: September 2024

Objective:This study systematically reviews the literature on the impact of environment temperature on industrial workers and the competitive capacity of industrial organizations.

Theoretical Framework:Research such as that by Ferrari et al. (2023) and Varghese (2018) indicates that the relationship between heat and occupational health is predominant, influencing productivity and economic costs. Borg et al. (2021) highlight the need to explore the economic impacts of heat in the workplace to develop effective management policies. Hariyani et al. (2022) emphasize the importance of integrating sustainability and technology into organizational strategies to increase competitiveness.

Method:Using the PRISMA protocol and the Science Direct, Web of Science, PubMed and Scopus databases, the research analyzed 329 documents from 31 journals.

Results and Discussion:The results indicate that high environment temperatures affect the physical and mental health of workers, reducing productivity. Organizations implement strategic actions and mitigation measures when they perceive competitive advantages. However, industries do not see environment temperature as a direct factor in reducing competitiveness, addressing it as secondary to the economic axis, which creates a knowledge gap.

Research Implications:This research allows organizations to create new strategies to mitigate risks that may reduce their competitive capabilities. In addition, it allows for the creation of direct actions for the thermal comfort of workers, due to the central role of human beings in the competitive capacity of industrial organizations.

Originality/Value:This work highlights a gap in the scientific literature and in organizational strategies in the search for competitiveness, since the main actors in the manufacturing process, the workers, who are the most affected by exposure to AT, are not seen as elements sensitive to environmental risk .

Proses pemesinan dapat dilakukan dengan menggunakan mesin milling. Dalam proses pemesinan, mata pahat merupakan hal yang penting untuk diperhatikan dalam penggunaanya untuk memotong logam yang keras. Pada proses pemesinan, parameter pemotongan merupakan faktor yang perlu dipertimbangkan sebelum melakukan proses milling. Penggunaan parameter pemotongan yang tidak tepat dapat berdampak pada keausan pada mata pahat pemotong. Penelitian ini dilakukan dengan tujuan untuk menganalisis pertumbuhan keausan yang terjadi pada mata pahat karbida end mill pada saat pemotongan baja SKD 11. Penelitian dilakukan dengan metode eksperimen dengan menggunakan mesin milling. Untuk mengamati pertumbuhan keausan yang terjadi pada mata pahat, maka kedalaman pemotongan divariasi antara lain 0,5, 1,0 dan 1,5 mm. Putaran spindle yang digunakan sebesar 1452 r/min. Proses pemesinan dilakukan dengan selang waktu 5 menit, setiap 5 menit pemesinan dihentikan untuk mengamati nilai keausan yang terjadi pada pahat potong. Nilai keausan cutting tool ditetapkan sebesar 0,3 mm. Apabila pada saat proses pemesinan nilai keausan yang ditentukan belum tercapai, maka proses pemesinan dilanjutkan. Dan bila nilai keausan sudah mencapai 0,3 mm maka pemesinan dihentikan dan diamati mata pahat tersebut. Proses milling selanjutnya dilakukan dengan meningkatkan kedalaman pemotongan , pada proses ini menggunakan cutting tool yang baru. Hasil yang diperoleh dari penelitian ini adalah bertambahnya kedalaman pemotongan memberi pengaruh terhadap cepatnya terjadi keausan pada mata pahat. Pada kedalaman pemotongan 1,5 mm, nilai keausan yang dicapai sebesar 0,31 dalam waktu 20 menit. Sedangkan pada depth of cut 0,5 dan 1,0 mm nilai keausan terjadi lebih lama yaitu 30 menit. Jenis keausan yang terjadi pada mata pahat karbida end mill adalah abrasive wear yang terjadi pada bagian tepi mata pahat. Keausan tepi terjadi karena adanya gesekan terus menerus antara mata pahat dengan benda kerja, sehingga bagian tepi mata pahat terkikis dan akhirnya terjadi keausan.

Proses pemotongan logam tidak dapat dipisahkan dengan penggunaan mata pahat potong. Sifat-sifat mata pahat potong memberi spesifikasi tersendiri terhadap parameter pemotongan. Pertimbangan utama yang dilakukan dalam pemilihan mata pahat potong bergantung pada jenis benda kerja yang digunakan dan proses pemotongan yang dilaksanakan. Berkembangnya bahan benda kerja terutama dalam menghasilkan sifat sifat yang memiliki ketahanan tinggi terhadap kekerasan dan juga suhu pemotongan hal tersebut memicu perkembangan jenis bahan mata pahat potong tersebut. Salah satu jenis mata pahat yang memiliki kekerasan dan ketahanan terhadap temperatur tinggi adalah keramik. Namun demikian, jika digunakan secara kontinu mata pahat akan mengalami keausan. Penelitian ini dilaksanakan bertujuan untuk mengetahui peningkatan terjadinya keausan pada mata pahat keramik ketika melakukan pemotongan baja paduan yang keras seperti AISI 4340. Percobaan dilakukan dengan menggunakan mesin bubut konvensional. jenis mata pahat digunakan dalam penelitian ini yaitu mata pahat keramik type TNGA 160404T02025. Parameter pemotonagan terdiri Kecepatan pemotongan : 140 m/min, 220 m/min, 350 m/min, Putaran spindel : 350 r/min, 710, r/min, 1120 r/min, Kedalaman pemotongan : 0.06 mm, 0.08 mm, 1.00 mm, Hantaran pemotongan : 0.2 mm. Proses pembubutan dilakukan dengan rentang waktu 3menit, maka setiap rentang waktu tersebut pembubutan dihentikan dan dilakukan pengamatan dan pengukuran keausan pada mata pahat. Mata pahat dianggap aus jika telah mencapai nilai 0.3 mm. Dari hasil penelitian diperoleh bahwa kecepatan potong (Vc) berpengaruh terhadap waktu penggunaan mata pahat sisipan. Semakin tinggi kecepatan potong (Vc) maka semakin rendah nilai waktu penggunaan mata pahat sisipan. Nilai keausan mata pahat tercepat yaitu pada menit ke-9 dengan kecepatan potong 350 m/min serta kedalaman potong 0,1 mm dan nilai keausan mata pahat terlama pada menit ke-72 pada kecepatan potong 140 m/menit dan kedalaman potong 0,06 mm.
