casas del posterremoto de San Juan
Authors: Cremaschi Veronica 
Published: July 2024

El 15 de enero de 1944 un sismo destruyó la ciudad de San Juan y alrededores, lo que condujo a su reconstrucción. Para ello se ensayaron diferentes tipos de viviendas cuya materialidad estuvo condicionada por la necesidad de dar albergue en un corto tiempo a las familias que habían perdido sus casas. Este artículo reconstruye los diferentes modelos empleados a partir de un exhaustivo trabajo de rastreo de fuentes que se encuentran disponibles en archivos provinciales y nacionales. Esto es así porque en el proceso de la reconstrucción intervinieron entidades de distintas jurisdicciones. Como resultado observamos que se recurrió a tipologías y materiales diversos. Esto diferencia el caso sanjuanino de otras provincias en que la vivienda estatal se concretó en el “chalecito” y, en menor medida, la vivienda en bloque, ambos de mampostería de ladrillo. A pesar del carácter experimental del caso sanjuanino, el Censo de 1960, nos indica que los materiales preponderantes continuaros siendo los tradicionales no antisísmicos.

Published: July 2024

Yes is More: un arquicómic sobre la evolución arquitectónica es una monografía en formato novela gráfica que fue publicada en 2009 por el estudio Bjarke Ingels Group (BIG). En este artículo se analiza la estrategia discursiva empleada por BIG en esa publicación. El análisis se fundamenta en el concepto aristotélico de ethos autoral. Para ello se estudian las relaciones que Yes is more tiene con el lenguaje y la retórica de los cómics, a través de la aplicación de algunas de sus convenciones y recursos. A partir del estudio de los tres primeros capítulos de la obra se establecen paralelismos y comparaciones con estrategias narrativas usadas en otros cómics y en reconocidas obras de divulgación. Como conclusión, se establece que la gradual introducción de recursos propios del cómic constituye un elaborado discurso proyectual que funciona como ethos autoral de BIG.
Study of Parameters of the Mixture and Heat Generation of the DD15 Diesel Engine of the Sandvik LH514 Loader in the Process of Using Alternative Fuels Based on RME
Authors: Bembenek Michał , Melnyk Vasyl , Mo Yurii 
Published: July 2024

Abstract
Today, there is a growing shortage of commercial motor fuels in the world. This is due to the tendency to regulate the extraction of hydrocarbons, which are the main raw materials for their production; and, therefore, to reduce the import of oil, alternative types of fuel for diesel engines based on oils and animal fats are becoming widespread today. In this regard, intensive work is underway to convert internal combustion engines to biofuel-based ones both in countries with limited fuel and energy resources and in highly developed countries that have the opportunity to purchase liquid energy carriers. Biodiesel fuel (biodiesel, PME, RME, FAME, EMAG, etc.) is an environmentally friendly type of biofuel obtained from vegetable and animal fats and used to replace petroleum diesel fuel. According to the results of modelling, in the process of using RME B100 biodiesel fuel, we found a reduction in nitrogen dioxide emissions by 21.5% and a reduction in soot emissions by 34.5%. This will positively affect the environmental performance of the Sandvik LH514 loader, which is especially relevant in closed environments such as mines. So, according to the results of studies of the operation of the DD15 engine of the Sandvik LH514 loader on commercial and RME B100 biodiesel fuel, it was established that the use of biodiesel fuel leads to a deterioration of the mixture, due to which heat generation is reduced and, as a result, fuel consumption increases and engine power decreases, but the aspect of environmental indicators constitutes the significant improvement demonstrated by the present work.
Assessment of Parameters of the Vibration-Based Energy Harvesting System Located in the Micro-Power Generator
Authors: Koszewnik Andrzej 
Published: July 2024

Abstract
This article presents the optimisation process of some key parameters such as the size of the macro-fibre composite (MFC) and the optimal impedance load matching the piezoelectric harvester located in the prototype of the micro-power generator to enhance the vibration-based energy harvesting effect. For this, the distributed parameter model of this structure, including MFCs of the 8514 P2, 5628 P2 and 8528 P2 types, with a homogenous material in the piezoelectric fibre layer was determined. The numerical analysis of the FEM model of the flexure strip with piezo-composite indicated that the highest amplitude of voltage >7 V is generated by the proposed device with the piezo of the 8528 P2 type, while the lowest amplitude (close to 1.1 V) was noted for the piezo of the 8514 P2 type. Experiments were carried out on the laboratory stand to verify the obtained results. In addition, it was shown that the power output of the real EH system with the piezo of the MFC 8528 type, connecting with the matched resistive load (R = 120 kΩ), led to a significant increase in the value of the generating voltage up to 500 mW versus EH system with the piezo of 8514 P2 and 5628 P2 types. Finally, the effectiveness of this system was found to be close to 33% for the EH system with the piezo of the 8528 P2 type.

Abstract
This research endeavour-investigates the enhanced adaptation of the Laplace-based variational iteration method (VIM) tailored specifically for tackling the Duffing Equation. This is accomplished by incorporating the Lagrange multiplier as a strategic tool to effectively address the inherent natural frequency within the Duffing Equation. Using a meticulous comparative analysis, here are juxtapose the analytical outcomes generated by the modified VIM approach with the numerical solution obtained through the application of the renowned Runge-Kutta Fehlberg method (RKF45), implemented by using the powerful mathematical software, MAPLE. Furthermore, by exploring the profound influence of diverse initial conditions on the resulting solution, a diverse array of distinct graphical representations is presented.

Published: July 2024

Abstract
Damping and energy-consuming elements can be found in many technical applications. This means these component types can prevent fractures or injuries in the case of products or people, respectively. In the last time, many modern applications and inventions associated with the reduction of the effects of an impact are observed especially in the mode of transportation safety area. The significant development of the automotive industry, increasing popularity of motorbikes, electric bikes and scooters, sports field, etc., require new solutions for personal safety protection. Human head and neck protection, and other body parts protection are typical groups of solutions from biomechanics and mechanical engineering. Authors have investigated LDPE-made pneumatic absorbers under axial impact force. Based on the experimental approach and analytical model, mechanical characteristics are presented. Impact force value, deceleration and damping for different loading conditions are shown. Because safety systems’ impact protective features can be matched to impact conditions, results indicated that absorber damping could possibly be a good solution for them, shaping the impact characteristics according to safety requirements.
Development of a Biomechanical Human Model for Safety Analysis of the Operators of Self-Propelled Mining Machines
Authors: Działak Paulina , Karliński Jacek , Maślak Paweł 
Published: July 2024

Abstract
In the paper, the authors presented an elaboration of the biomechanical model of a human in a sitting position for the dynamic tests related to the impact loads acting on operators of self-propelled mining machines. Here, the human body was replaced with a one-dimensional multi-mass model (in the form of concentrated masses connected with elastic and damping elements). The models of this type are currently used to study ergonomics in vehicles. However, their use is limited because they are adapted to much lower dynamic loads than those acting on the operator in accident situations in mines. Many models of this type, in which the stiffness and damping characteristics of the elements are constant, have been described in the literature. Due to the specificity of the analysed loads acting on the operator, the literature studies were mainly focused on models for vertical forces analysis. By developing non-linear stiffness characteristics, in the currently used car seat ergonomics linear biomechanical models, it was possible to use simple multi-mass models with several degrees of freedom to analyse the effects of dynamic excitation characterised by large displacements. The validation of the developed characteristics was performed using a full-size dummy in a sitting position positioned in the cabin, on the operator’s seat.
Evaluation of Some Thermophysical Properties of SN500 Lubrication Oil Blended with SIO2, AL2O3 and TIO2 Nano-Additives, Using Fuzzy Logic
Authors: E Sankar , K Duraivelu 
Published: July 2024

Abstract
Nano-additives are generally blended with the base lubricant oil, to enhance the lubricant characteristics such as wear, coefficient of friction (CoF), thermal conductivity, density, and flash and fire points of the lubricant. In this research, nano-additives of SiO2, Al2O3 and TiO2 are blended with the base SN500 oil with different proportions of mixture. When these three nanoparticles are used together in base oil, they enhance most of the desirable properties of a lubricant; 27 samples with three different levels of a mixture of nano-additives are identified using factorial design of experiments. The experimental outcomes for the selected three characteristics of interest of density, flash point and fire point are determined. Conducting experiments for ‘n’ number of samples with different proportions of mixture of nano-additives is a cumbersome, expensive and time-consuming process, in order to determine the optimum mix of nano-additives for the desirable level of characteristics of interest. In this research, attempt has been made to apply fuzzy logic to simulate a greater number of samples with different proportions of a mixture of three nano-additives with the respective outcomes of characteristics of three thermophysical properties. Out of the numerous samples simulated using fuzzy logic, the sample with the optimum mix of three nano-additives of SiO2, Al2O3 and TiO2 blended with the base oil is identified for the desirable level of characteristics of interest of density, flash point and fire point. The values of the identified sample are found to be at the desirable level of 0.9008 gm/ml, 231°C and 252°C, respectively.
Phenomenal Intentionality and the Temporal Shape of Experience
Authors: Stratman Christopher M. 
Published: July 2024

Abstract
This paper argues for the claim that the mental ontology required for what has been called the “Phenomenal Intentionality Theory” (PIT) should be understood in terms of mental events or episodes, not mental states that instantiate phenomenal properties because the former but not the latter has a kind of temporal shape. I begin by laying out the basic commitments of PIT. I then introduce the notion of “temporal shape” and defend the following simple but powerful argument: (1) If conscious experiences are phenomenal mental states that instantiate phenomenal properties, then the phenomenal character of these experiences will lack a temporal shape. (2) The phenomenal character of conscious experience typically has a temporal shape. (3) Therefore, conscious experiences are not mental states that instantiate phenomenal properties.

Published: July 2024

Abstract
From 2016 to 2021, nematode surveys in Florida strawberry fields revealed several species of foliar nematodes (Aphelenchoides spp.). Aphelenchoides besseyi sensu stricto was detected only in 2016 and 2017 on photosynthetic strawberry leaves/buds, but other not well characterized populations of Aphelenchoides sp. were found on declining/dessicated leaves. Morphological analyses showed that these samples of Aphelenchoides sp. consisted of A. bicaudatus, a species detected in Florida for the first time, and A. rutgersi, a species previously reported in Florida from the citrus rhizosphere. These two species differed from A. besseyi in the shape of their tail terminus: bifurcate in A. bicaudatus; mucronate with a ventral thin mucro in A. rutgersi; and stellate in A. besseyi. One population each of these species was used for morphological and molecular analyses after being reared on Monilinia fructicola. Body and tail length differences were observed among Florida A. bicaudatus and other populations from the Far East and South Africa. Phylogenetic analyses of the rRNA gene sequences showed that Florida A. bicaudatus grouped with those of species from South Korea, Taiwan, and the Netherlands and several other populations listed as Aphelenchoides sp. from Brazil, Costa Rica, and Japan, which were considered as representatives of A. bicaudatus in this study. Similarly, sequences of Florida A. rutgersi grouped with those from environmental samples in Japan and North Carolina, which were listed as Aphelenchoides sp. and were considered as representatives of A. rutgersi in this study. Photosynthetic strawberry leaf samples were free from both A. bicaudatus and A. rutgersi, indicating that these two species did not damage strawberry. They were associated with desiccated leaves and/or propagative stolons, usually infected by fungi, confirming that they are mycetophagous under field conditions in this study. Results of soybean leaf inoculation on moist filter paper containing A. bicaudatus specimens showed that this species could become phytophagous under artificial conditions. Nematodes penetrated the leaf epidermis and migrated into the mesophyll causing leaf tissue discoloration/necrosis, which remained localized within the infested area. Soybean leaf damage was almost negligible, and no nematode reproduction was observed in the inoculated soybean areas.
Normativity in Languaging and Practical Activity
Authors: Gahrn-Andersen Rasmus 
Published: July 2024

Abstract
The paper explores some of the commonalities between language and practical activity. It focuses on the normativity involved and presents an account on two different kinds of normativity which constrain both languaging and practical doings in general. In this connection, the paper engages with the first-order—second-order distinction central to the Distributed Language Perspective and shows that there is a way for proponents of this perspective to come to terms with linguistic normativity without presupposing a dualism between, on the one hand, first-order articulations and, on the other, the second-order normative constrains that condition them.
An opportunity missed is an opportunity lost. Flood maps and their (non-)utilization by local government bodies in the Czech Republic
Authors: Klemešová Kamila Dolák , Andráško Ivan , FIedor David , Dolák Lukáš 
Published: July 2024

Abstract
Flood maps are a crucial component of integrated flood risk management. While their key role is commonly acknowledged by experts and scholars, however, literature and findings on the practical utilization of flood maps (including the user’ experiences) within the processes of governance are scarce. Our study aims to contribute to closing this gap; by focusing on the Czech local government bodies, data collected through a questionnaire survey allowed us to examine (a) how, or whether at all, the officials employ flood maps in their agendas; (b) how do they experience and assess working with the maps; and (c) which data would they supplement the extant flood maps by. Our findings show that the praxis of local flood-related governance in the Czech Republic still largely neglects the up-to-date approaches and practices of flood risk management. The officials addressed mostly continue to rely on the earliest type of floodplain maps and purely technical aspects of floods, while largely omitting the newer flood danger and risk maps; thus, they are also missing the opportunities of applying multi-criteria assessment of the flood risk and more effective communication with the public. The paper concludes with a set of suggestions for relevant praxis and future research.
The Role of Coaching in University Start-Up Creation: A Study of Students from Badji Mokhtar Annaba University
Authors: Afif Hana , Belaid Mohamed Mouloud , Radu Valentin 
Published: July 2024

Abstract
This research paper addresses a central problem: how coaching assists university students in launching startups and transitioning into entrepreneurs. This study aims to analyze to what extent coaching contributes to helping university students start their own projects at the level of the faculty of Economics, Commerce, and Management. The study's findings highlight several key points, the most important of which is that coaching has become a path to follow, especially since it led students to adopt an entrepreneurial orientation, which also allowed them to dissipate their fear and talk about their ideas for their project. Moreover, coaching made it possible to realize the talents enabling the student to innovate in a project/create a start-up. However, the study also identifies certain shortcomings, the most important of which is that the training did not help some students to prepare their first model, and it is, therefore, advisable to subsequently train a specialized coach for each student and that he starts with him from the beginning until his idea came to fruition on the ground.

Pemilihan moda transportasi berbeda-beda berdasarkan tingkat kepuasan yang difasilitasi oleh masing-masing moda transportasi. Trans Koetaradja merupakan salah satu angkutan umum yang menjadi pilihan masyarakat di Kota Banda Aceh. Keberadaan bus Trans Koetaradja yang kurang diminati pelaku pergerakan memicu meningkatnya penggunaan kendaraan pribadi, khususnya sepeda motor. Kecenderungan yang terjadi dalam pemilihan moda transportasi, masyrakat lebih memilih pada kendaraan yang mampu meminimumkan waktu dengan biaya yang murah. Pemilihan moda juga dipengaruhi oleh karakteristik pengguna transportasi itu sendiri. Penelitian ini bertujuan untuk mengetahui bagaimana karakteristik pengguna perjalanan di Kecamatan Kuta Alam. Hasil penelitian ini menunjukkan bahwa karakteristik pengguna perjalanan yang ada di Kecamatan Kuta Alam didominasi oleh mahasiswa yang memiliki pendapatan di bawah Rp.1.000.000 dengan rentang usia 15 – 24 tahun yang berjenis kelamin dominan perempuan. Adapun rentang waktu pergerakan yang dipilih oleh pengguna ialah pada jam06.00 – 08.00 WIB yang mana waktu tersebut merupakan jam yang digunakan untuk melakukan aktivitas ke kampus untuk berkualiah ataupun bekerja menuju ke kantor. Dari hasil tersebut diketahui hanya terdapat satu variabel yang berpengaruh secara signifikan terhadap pemilihan moda, yaitu variabel Waktu Tempuh. Maka, didapatkan hasil bahwa probabilitas pemilihan moda sepeda motor sebesar 55%. Sedangkan pemilihan moda Trans Koetaradja sebesar 45%.
PENGGUNAAN CULTIVATOR POWER WEEDER SEBAGAI PENGENDALI GULMA SECARA MEKANIS PADA TANAMAN SAYURAN

Published: July 2024

Farmers in Lieue Village, Darussalam District, Aceh Besar still use the handweeding method to control weeds in vegetable crops. This method takes a long time, making the weed control process less effective. In addition, the small amount of labor is not proportional to the area of vegetable crops, so the weed control method is less efficient. To overcome this, the partner community is offered a solution to the mechanical weed control method, namely by using a cultivator power weeder. The weed control tool offered is an engine-driven tool mounted on an iron frame with two iron wheels equipped with blades that function as soil cultivators and weed cutters. When the machine is turned on and running, the soil will be processed while cutting weeds and controlling weeds. The cultivator power weeder offered is an innovation developed by the Weed Management Laboratory of the Agrotechnology Study Program and the Agricultural Equipment and Machinery Laboratory of the Faculty of Agriculture, Syiah Kuala University. It is hoped that with this weed control tool, the weed control process in vegetable crops can be more effective and efficient and ultimately can increase the yield of vegetable crops of farmers in Aceh Besar. The results of the service showed that the service team had succeeded in making a power weeder cultivator as a mechanical weed controller using a driving machine. However, the tool that has been made turns out to be rather difficult to move. Therefore, wheels were added to the front to make it easier to move. This tool can be used for weed control in horticultural and food crops. To date, farmers have tried and used the power weeder cultivator as a mechanical weed controller to control weeds in vegetable crops in various target villages.
