Published: June 2024

The chytrid fungus Batrachochytrium salamandrivorans [Bsal] is causing declines in the amphibian populations. After a decade of mapping the pathogen in Europe, where it is causing dramatic outbreaks, and North America, where its arrival would affect to the salamander’s biodiversity hotspot, little is known about its current status in Asia, from presumably is native. Japan has several species considered as potential carriers, but no regulation is implemented against Bsal spreading. Previous Bsal known presence detected various cases on the Okinawa Island, southwestern Japan. Previous studies on its sister species, B. dendrobatidis presented a high genomic variation in this area and particularly on Cynops ensicauda. Here, we have done the largest monitoring to date in Japan on the Cynops genus, focusing on Okinawa Island and updating its distribution and providing more information to unravel the still unknown origin of Bsal. Interestingly, we have provided revealing facts about different detectability depending on the used molecular techniques and changes in its Japanese distribution. All in all, the Bsal presence in Japan, together with its low variability in the sequenced amplicons, and the lack of apparent mortalities, may indicate that this part of Asia has a high diversity of chytrids.

Információs folyamatok digitalizációjának hatása a kontrolleri szakmára – Szisztematikus irodalomáttekintés
Authors: Szukits Ágnes , Sztrida Lilla , Szabó Inez Anna
Published: June 2024

A cikk a nemzetközi irodalom szisztematikus áttekintése alapján keresi a választ arra a kérdésre, hogy az információs folyamatok digitalizációja miként alakítja a kontrollerek vezetői döntéstámogatásban betöltött szerepét. Az átalakulás motorját a megnövekedett adatmennyiség és a fejlett adatelemzési technikák elterjedése jelenti. Ugyanakkor a rendelkezésre álló, a döntések szempontjából releváns ’új típusú’ adatok már nem elsősorban pénzügyi, számviteli jellegűek, ezért a döntéstámogató adatelemzés terén más szakmai csoportok is megjelentek. A változások joggal vetik fel a kérdést, hogy milyen hozzáadott értéket tud teremteni a kontroller a vezetői döntéstámogatásban és hogyan teszi azt. Az áttekintett irodalom szintézise alapján az adatelemzésben a kontrollerek szerepe marginalizálódik, míg az elemzési eredmények interpretációja, a ’sense-making’ és az adatok iránti bizalom erősítése terén jelentőségük nő. Az adatelemzés fejlődése, a vállalati gyakorlat átalakulása egyúttal fontos hatásköri problémákhoz vezet: nemcsak más szakmai csoportokkal, hanem magával a technológiával való együttműködés is új kérdéseket vet fel.
Educação superior e cidadania democrática:
Authors: Martins Leandro José de Souza
Published: June 2024

O objetivo desse texto é defender a importância de resgatar a educação – especialmente a Educação Superior – como processo preparo para o exercício da cidadania e o estímulo para conhecer os problemas do mundo presente. Para isso, defende que em todas as graduações, sobretudo da Área STEM (Ciência, Tecnologia, Engenharias e Matemáticas, conforme acrônimo em inglês), a Educação Superior não só se faça com preparação para o mundo do trabalho mas também oportunidade de estudos e pesquisas de cunho mais político, ético ou filosófico, realizando o que a legislação educacional sintetiza como preparo para o exercício da cidadania e enfrentamento dos problemas do mundo atual. Para tanto, o texto argumenta que os processos educacionais devem se realizar como uma prática democrática, como uma educação em torno de valores e posturas republicanas, com ênfase na tolerância. Como indicado na conclusão, considera-se que a tolerância não só desempenhe o papel de um objetivo, mas também seja um elemento constitutivo da Educação. A educação pela e para tolerância articular-se-ia como um passo fundamental para realizar o escopo da Educação Superior, conforme preconizado pela legislação vigente e para superar todo tipo de objeção ou insensibilidade dos estudantes que, ainda nos primeiros anos da graduação, perdem o interesse ou entendem como inúteis discussões acerca da ética, da política e de outras questões sociais. A metodologia adotada é, primordialmente, descritiva-analítica, mediante uma revisão bibliográfica que venha servir como fundamentação de futuras abordagens empíricas. Autores clássicos, cotejados dentro do possível com pesquisadores contemporâneos, formam o referencial teórico aferido pela pesquisa bibliográfica e documental.

Authors: Szymiczek Małgorzata , Sarray Sara , Chomiak Monika , Chmielnicki Błażej , Gajlewicz Izabela
Published: June 2024

The study examined the influence of selected inorganic fillers (5 and 10% by mass) on the foaming process, physicochemical properties, and structure of self-extinguishing polyurethane foam (density of approx. 35 kg/m3) obtained by reacting polyol with isocyanate (100:110). The filler used was bentonite (B), lamellar graphite (G), dendritic copper (Cu), aluminum oxide (Al2O3) and silicon carbide (SiC) and Al2O3/SiC mixture (1:1). Stereoscopic microscopy was used to determine the structure. The functional properties were examined based on density, water absorption and fire resistance. The course of the foaming reaction depends on the content, type, and physicochemical properties of the filler. The addition of bentonite increases water absorption and Al2O3 reduces flammability of the foam.

Authors: Febriyanti Maya Putri , Hendrijanto Kris , Poerwanti Sari Dewi
Published: June 2024

PT. Perkebunan Nusantara (PTPN) XII, as part of its corporate social responsibility, aims to enhance economic activity in the Mount Gambir area through Agro Rengganis Tourism (WAR), with the primary goal of fostering image development through empowerment. This qualitative study seeks to identify the various motives underlying empowerment initiatives in the Mount Gambir region, employing the theory of legitimacy as its perspective. The research reveals that PTPN XII employs an independence model in its empowerment process, focusing on improving community welfare via Rengganis Agro Tourism. This model involves providing the community with the autonomy to identify and harness the potential of their natural surroundings. PTPN serves as a facilitator, offering necessary developmental support such as training and education. This approach proves effective in elevating the standard of living for the local population. However, the study highlights a notable gap in the sustainability aspect of the empowerment process. The current program tends to prioritize image-building and maintaining positive relations between PTPN XII and the community, potentially overlooking long-term sustainability efforts.

Mobilitas Penduduk dan Kualitas Udara saat Pandemi COVID-19: Studi kasus DKI Jakarta
Authors: Alamsyah Purnama , Hakim Lukman Nul
Published: June 2024

Penelitian ini bertujuan melihat sejauh mana mobilitas penduduk berpengaruh terhadap lingkungan, khususnya kualitas udara. Para peneliti sebelumnya telah mempelajari dampak mobilitas penduduk dan kaitannya dengan ekonomi, pola penyebaran penyakit, dan psikologis.  Namun demikian masih sedikit yang meneliti bagaimana faktor lingkungan mempengaruhi dan dipengaruhi oleh mobilitas manusia. Bencana covid-19 secara kebetulan memberikan peluang bagi peneliti untuk mempelajari dengan kondisi yang sulit terulang, yaitu kondisi Kota Jakarta yang lebih lengang, dikarenakan mobilitas penduduk di Jakarta yang menurun drastis dikarenakan lockdown. Peneliti berusaha mempelajari fenomena tersebut menggunakan kerangka teori Driver–Pressure–State–Impact–Response (DPSIR). Metode penelitian yang dilakukan adalah kualitatif dengan mengkaji data mobilitas dari Google Mobility Index dan Rom tom Traffic index. Sementara sumber data respon publik diambil dari data cuitan di twitter yang diambil dari Twitter Archiving Google Sheet (TAGS) versi 6.1.7 mulai dari tanggal 15 Februari hingga 22 Mei 2020. Hasil penelitian menunjukkan bahwa penurunan mobilitas penduduk dalam berkendara ternyata tidak secara otomatis akan menurunkan kadar polutan di udara. Terdapat faktor lain yang berkontribusi terhadap polusi di Jakarta, yaitu industri yang berada di Jabodetabek yang mengelilingi Kota Jakarta. Artikel ini bermanfaat bukan saja bagi pemerhati lingkungan, melainkan juga para pengambil kebijakan, bahwa upaya memperbaiki kualitas udara di Kota Jakarta dapat dilakukan dengan mengatur mobilitas penduduk di Kota Jakarta, dan memonitor pihak industri.

Published: June 2024

The snack food industry is one of the major industries in Indonesia that has various types of products, one of which is snacks (cookies), which are widely consumed as snacks. This study aims to determine the characteristics of wastewater from the snack food industry (cookies). The research was conducted in three factories located in Bandung Regency, Sumedang Regency and Majalengka Regency. Primary data were collected from wastewater samples collected monthly for laboratory testing. Data analysis used descriptive statistical analysis of average concentration of wastewater parameters using Microsoft Excel software and SPSS 25 software. The main parameters of wastewater from the snack food industry (cookies) are pH, TSS, BOD, COD, ammonia, total nitrogen, and MBAS. From the comparison of the resulting BOD, COD, TSS, ammonia, and total nitrogen pollutant loads, the largest load trends occur in Factory B, Factory C, and Factory A. Failure to properly treat these crucial wastewater parameters can pose risks to the environment and surrounding communities. Thus, these vital parameters form the basis for selecting wastewater treatment plant technology to fulfil environmental standards. WWTP process recommendations that can be used are grease trap, surge tank, dissolved air flotation (DAF), anaerobic system, aerobic system, secondary clarifier, and post-treatment.

Authors: Megawati Tri Furi , Rahma Melati Julia , Semedi Bambang , Afandhi Aminudin
Published: June 2024

The broader transformation of forested areas into open land is commonly referred to as deforestation. Deforestation poses a significant challenge to forest preservation and environmental sustainability. This study aims to employ remote sensing methods to analyze the spatial patterns of deforestation in the Soeharto Forest. It is complemented by in-depth interview data gathered from individuals engaged in forest exploitation activities. The findings reveal a notable decline in land cover within the Soeharto Forest Park area from 1992 to 2022, resulting in a reduction to 335,994,000,000 m2. Further analysis of the in-depth interview data indicates that forest fringe communities have taken control of 15,536,393.69 m2 of land to fulfill their livelihood and cultivation needs. The decline in land cover will also be more critical because of moving the national capital. The research results also discussed land cover areas using remote sensing. However, social support discusses whether land cover change is caused by land tenure by forest fringe communities and plans to relocate the national capital. Where this is also influenced by the formulation of government policies that have not balanced bee interests of ecology and the social culture ture of the community.

Published: June 2024

This study investigates the integration of Local Ecological Knowledge (LEK) in the sustainable development of Banyuwangi Liberica coffee, focusing on coffee farmers' ancestral heritage and local knowledge systems. Practices in land management, cultivation techniques, pest control, and pruning waste utilization are examined. Through qualitative data analysis from interviews and field observations, the research highlights the depth and significance of LEK in maintaining environmental sustainability and cultural heritage. Liberica coffee farmers possess a wealth of inherited LEK, encompassing ecological dynamics, sustainable agriculture, and natural resource conservation. Farmers integrate this knowledge into decision-making, evaluating innovations through research trials. Adopting appropriate practices preserves local ecosystems and maintains Liberica coffee's authenticity. The study underscores LEK's crucial role in land management and cultivation, with seedlings and repurposing waste for soil fertility. Pruning and using shade plant branches optimize fruit production and microclimate regulation. Natural pest control minimizes chemical pesticide use, preserving the coffee ecosystem's delicate balance and supporting biodiversity. Integrating LEK not only fosters environmental sustainability but also strengthens the community's social and cultural fabric. Coffee farmers' ancestral heritage and deep connection with the land contribute to the resilience of local agricultural practices, promoting the well-being of both farmers and the ecosystem.

Authors: Arsanata Kholifah Maulidya , Pawenang Eram Tunggul
Published: June 2024

Households with access to wastewater sewerage in Pamotan in 2022 only be 69.9%. This study aims to find out the factors related to household wastewater sewerage ownership in the Pamotan Community Health Center Working Area. This research was an observational analytic using a cross-sectional design. The research population was all families in Pamotan subdistrict villages with the lowest ownership of wastewater sewerage, with a sample size of 90 families. The independent variables are land availability, length of year residence, knowledge, education, and income for the dependent variable, that are ownership of the Waste Water Sewerage. The data were analyzed using univariate and bivariate statistics, employing the Chi-Square test. The results of the study showed that land availability (p=0.04), education level (p=0.018), knowledge level (p=0.003), and income (p=0.00) are related to household wastewater disposal ownership while the length of year residence (p=0.257) is not related to ownership of household wastewater sewerage in the Pamotan Subdistrict. Based on the research results, the length of year residence is not related to household wastewater sewerage ownership because people's old habits that are not good at managing household wastewater result in wastewater sewerage ownership behavior not fulfilling standards.

Published: June 2024

Hydrogen gas is considered a pollution-free fuel in the future. However, the EC process using these non-sacrificial electrodes requires further research especially for the production of dissolved hydrogen gas and the efficiency of microalgae harvesting. The purpose of this study was to investigate the concentration of dissolved hydrogen gas produced from the harvesting process of Dunaliella salina microalgae species using EC and ORP concentrations including pH, harvesting efficiency due to voltage variations and harvesting time using EC with non-sacrificial electrodes. D salina harvesting using EC reactor made of cylindrical borosilicate glass. Spiral-shaped type 304 stainless steel (non-sacrificial) serves as the cathode and solid cylindrically-shaped Fe serves as the anode. The voltage set varies between 16, 18, and 20 Volts, while the electrolysis time is varied between 1.3.5 minutes. The results showed that the highest dissolved hydrogen concentration of 820 ppb (0.820 ppm) produced from the EC process used 18 V for 3 minutes. The volume of gas could not be measured because most of the hydrogen gas was dissolved in the D salina culture, so it was not enough to evaporate within 3 minutes. The maximum ORP concentration of -413 mV resulting from the EC process uses 18 V for 3 minutes. When hydrogen gas is present in a solution, it can decrease the ORP value of the solution. At EC time with non-sacrificial electrodes for 5 minutes managed to harvest D salina 50.79%; 61.90%; 74.60% at voltages of 16 V, 18V, and 20 V respectively.
Detection of Actinic Keratosis Skin Cancer Using Gray Level Co-occurrence Matrix Texture Extraction and Color Extraction With Support Vector Machine Classification
Authors: Putra Leonardus Sandy Ade , Gunawan Vincentius Abdi , Saragih Agus Sehatman
Published: June 2024

Nowadays, humans tend to carry out activities during the day, both indoors and outdoors. Activities carried out outdoors cause human skin to often receive direct exposure to sunlight, which contains ultraviolet (UV) rays. Direct exposure to UV rays on the skin will harm the skin's health, which is the covering of the human body. Harmful effects on the skin usually include the skin becoming dark and dull, burns, and even causes cancer. One of the skin cancers that may appear on human skin is Actinic Keratosis (AK) cancer. AK cancer is a type of cancer that is classified as benign and can be cured with medical help. However, if this cancer is not caught early, it can become Squamous Cell Carcinoma (SCC), a type of malignant cancer. This research aims to design a system for identifying AK cancer types using color and texture feature extraction. RGB color feature extraction is obtained from image color segmentation and RGB values. The Gray Level Co-occurrence Matrix (GLCM) method is used to determine the texture of the skin cancer. Identification is carried out by a classification process using a Support Vector Machine (SVM), which can recognize the type of AK cancer. This research uses three classification methods: classification with color extraction, classification with texture extraction, and classification with color and texture extraction. Research shows that the highest level of accuracy in cancer recognition reaches 96% by combining color and texture extraction results as classification determinants. So, the system designed has succeeded in recognizing the type of AK cancer early on..

Authors: Khafidh Muhammad , Irfan Afi Muhammad , Suryawan Donny , Kistriyani Lilis , Ismail Rifky
Published: June 2024

Indonesia is the world's second-largest producer of natural rubber. Various products can be made of natural rubber. One of them is a foot prosthesis. An essential criterion for foot prosthesis is a significant value of friction force to prevent slip during usage. The present study optimizes natural rubber formulation to obtain the largest friction force value. A pin-on-disk tribometer is used to obtain friction force values. The optimization method used in the present study is Taguchi Method Orthogonal Array L9, while the contribution of each control factor to increase friction is carried out using ANOVA analysis. Four control factors are used in this study: the type of natural rubber, the percentage of silica powder, the percentage of sulfur, and the vulcanization temperature. Each control factor has three different levels. The test results showed that the optimum formulation to obtain the highest friction value is a mixture of concentrated natural rubber and instant natural rubber, 30 phr of silica powder, 5 phr of sulfur, and 150°C of vulcanization temperature. The friction force of the optimum formulation increases by 33% compared to the baseline formulation. ANOVA analysis shows that the vulcanization temperature is the most crucial factor in increasing the friction force, contributing 62.58%.

Published: June 2024

In the project implementation process, there is still the possibility of delays, as in the case of the Tanjung Buyut I Tug Boat ship repair project - 206 135 GT calculations are needed to accelerate the project to determine the optimum time and cost. One method that can be used in accelerating projects / crashing projects is the Time Cost Trade-Off method. This method can be used to solve this problem by adding specific alternatives such as working hours, labor, and other things with the minimum additional cost. In this study, an alternative acceleration was carried out by adding manpower and working hours duration of 1 to 4 hours which would be applied to the Hull repair project for the Tug Boat Tanjung Buyut I-206 135 GT. Based on the results of the analysis that has been carried out on the work of the Hull section, which is included in the critical activity, it is obtained that the most optimum duration acceleration is the addition of working hours (overtime) for 3 hours and an additional workforce of 24 peoples which results in an acceleration of time of 17 days from the normal duration of 60 days to 43 days with a time efficiency of 28%, as well as a cost reduction of IDR 19,700,000 or around 3.34% compared to the normal duration fee of IDR 571,950,000 to IDR 552,250,000.
Resisting Ireland’s Necropolitics of Asylum: Refugee Voices in Irish Literature and the Arts
Authors: Rosende-Pérez Aida
Published: June 2024

This article examines the representation of the Irish Asylum system – known as Direct Provision – by an artist and a writer who have experienced it first-hand. Vukašin Nedeljković’s art project Asylum Archive (2007 –) and Melatu Okorie’s short stories “Shackles” (2010) and “This Hostel Life” (2017) respectively engage in the visual and literary representation of unlivable life in this carceral system, both articulating a compelling critique of the necropolitical violence exerted in and through its operations. Their work foregrounds the spatial and time dimensions of detention, highlighting the vulnerability of international protection applicants whose lives are not only bounded by confinement but also deferred in indefinite waiting. Besides, this article contends that these works go far beyond critique, offering very powerful critical insights into the inmates’ affective responses to the injustices of the asylum regime, and how these can potentially open spaces of dissent and resistance.
Monitoring of a rockfill embankment dam using TLS and sUAS point clouds
Authors: Bolkas Dimitrios , O’Banion Matthew , Laughlin Jordan , Prickett Jakeb
Published: June 2024

Terrestrial laser scanning (TLS) and camera-equipped small unmanned aircraft systems (sUAS) are two methods that are often used to produce dense point clouds for several monitoring applications. This paper compares the two methods in their ability to provide accurate monitoring information for rockfill embankment dams. We compare the two methods in terms of their uncertainty, data completeness, and field data acquisition/processing challenges. For both datasets, we derive an error budget that considers registration and measurement uncertainty. We also proceed to merge the TLS and sUAS data and leverage the advantages of each method. Furthermore, we conduct an analysis of the multiscale model-to-model cloud comparison (M3C2) input parameters, namely projection scale, normal scale, and sub-sampling of the reference point cloud, to show their effect on the M3C2 distance estimation. The theoretical methodologies and practical considerations of this paper can assist surveyors, who conduct monitoring of rockfill embankment dams using point clouds, in establishing reliable change/deformation estimations.

Published: June 2024

Objectives

Resistance to apoptosis in esophageal squamous cell carcinoma (ESCC) constitutes a significant impediment to treatment efficacy. Exploring alternative cell death pathways and their regulatory factors beyond apoptosis is crucial for overcoming drug resistance and enhancing therapeutic outcomes in ESCC.

Methods

Mammalian Ste 20-like kinase 1 (MST1) is implicated in regulating various cell deaths, including apoptosis, autophagy, and pyroptosis. Employing enhanced ascorbate peroxidase 2 (APEX2) proximity labeling coupled with immunoprecipitation-mass spectrometry (IP-MS), we elucidated the interactomes of MST1 across these three cell death paradigms.

Results

Proteomic profiling unveiled the functional roles and subcellular localization of MST1 and its interacting proteins during normal proliferation and various cell death processes. Notably, MST1 exhibited an expanded interactome during cell death compared to normal proliferation and chromosome remodeling functions consistently. In apoptosis, there was a notable increase of mitosis-associated proteins such as INCENP, ANLN, KIF23, SHCBP1 and SUPT16H, which interacted with MST1, alongside decreased expression of the pre-apoptotic protein STK3. During autophagy, the bindings of DNA repair-related proteins CBX8 and m6A reader YTHDC1 to MST1 were enhanced. In pyroptosis, LRRFIP2 and FLII which can inhibit pyroptosis increasingly binding to MST1.

Conclusions

Our findings delineate potential mechanisms through which MST1 and its interactomes regulate cell death, paving the way for further investigation to validate and consolidate these observations.
Défis sémiotiques de l’écriture du mort dans la littérature de la tombe
Authors: Bernoussi Mohamed
Published: June 2024

Cet article aborde la question du corps après la mort telle que la tradition arabo-musulmane le décrit d’abord dans le Coran et les hadiths (paroles du prophète Mahomet), puis dans l’abondante littérature de 'Adhâb al-Qabr (les terreurs salutaires de la tombe). C’est un sujet qui est étroitement lié à la sémiotique du corps, à la sémiotique de la religion et à la sémiotique de la culture car il est au carrefour de diverses problématiques relatives à la communication entre corps finis et vivants, au rôle structurant des lieux comme la tombe, l’au-delà ou dar al barzagh (équivalent – avec nuance – du purgatoire chrétien), et aux stratégies utilisées pour produire du sens dans un monde qui se veut intemporel, sans sens et sans espace, celui de la mort. Quel corps la tombe postule-t-elle ? Comment le récit du tombeau, avec ses catégories finies, joue-t-il avec un corps nié, mais en même temps indispensable ? On s’intéressera particulièrement à la question de la spatialité de la tombe, de la caractérisation du mort, de la nature des mondes possibles de la tombe, ainsi qu’à d’autres questions relatives au pacte communicatif qui s’établit entre le corps du mort et ceux des vivants.
Maquiavel: o Príncipe que não houve
Authors: BATISTA Nilo
Published: June 2024

Conceived as a lecture for a Criminal Policy course in progress, this text investigates the dispersion of punitive power in the cities of the northern Italian peninsula, a dispersion that delayed the formation of an Italian national state. Unlike the concentration of punitive power taking place in other countries, the peculiar economic and political process of those cities - whose governing models are briefly examined - prevented absolutist centralization. The central object of the analysis is Machiavelli's negative preventive-general criminal policy, which is based on historical bibliographical sources.
Atrial Fibrillation and Adipokines: A Pathophysiological Perspective
Authors: Rafaqat Saira , Noshair Iqra , Arif Mehnaz , Hafeez Ramsha , Maqbool Ayesha
Published: June 2024

Atrial fibrillation (AF) is a prevalent cardiac arrhythmia characterized by irregular and frequently rapid electrical activity in the atria. Adipokines are bioactive molecules that are secreted by adipose tissue, and exert diverse effects on health and disease. Obesity is a complex condition influenced by multiple interconnected factors, and the specific mechanisms linking obesity to AF may vary among individuals. Obesity contributes to the development of atrial arrhythmia. Moreover, obesity plays major roles in the pathophysiology of AF and its associated complications by inducing systemic changes, including altered hemodynamics, heightened sympathetic tone, and a persistent low-grade inflammatory state. Although the associations between overweight or obesity and elevated risk of AF have been established, the underlying mechanisms remain incompletely characterized.

Interspecies comparisons are key to deriving an understanding of the behavioral and neural correlates of human cognition from animal models. We perform a detailed comparison of the strategies of female macaque monkeys to male and female humans on a variant of the Wisconsin Card Sorting Test (WCST), a widely studied and applied task that provides a multiattribute measure of cognitive function and depends on the frontal lobe. WCST performance requires the inference of a rule change given ambiguous feedback. We found that well-trained monkeys infer new rules three times more slowly than minimally instructed humans. Input-dependent hidden Markov model–generalized linear models were fit to their choices, revealing hidden states akin to feature-based attention in both species. Decision processes resembled a win–stay, lose–shift strategy with interspecies similarities as well as key differences. Monkeys and humans both test multiple rule hypotheses over a series of rule-search trials and perform inference-like computations to exclude candidate choice options. We quantitatively show that perseveration, random exploration, and poor sensitivity to negative feedback account for the slower task-switching performance in monkeys.

Rights and access to land are major pressing issues among mainly first-generation agroecological farmers in the Netherlands. Due to short-term tenure contracts and high land prices, these farmers face an insecure future. Because of this, they are often unable to make long-term ecological investments, such as planting trees and taking measures to improve soil health. A growing group of farmers are devising new, more communal forms of land ownership and tenancy, that counter market forces and existing policies. In this article, we shed light on these farmers’ discourse and how it informs the construction of new forms of land ownership and tenancy. In the related research project written and led by farmers, information has been gathered in the form of meeting minutes, interviews covering problems and perspectives related to the land tenure regulation, and commons. This information has been systematized and validated by farmers. Agroecological farmers find themselves in an uncomfortable situation that is challenging in 2 ways. On the one hand, they are calling for revision of land tenure regulations to ensure long-term land contracts for their existence and on the other hand they are seeking to replace property rights in favor of more collective possession-based arrangements. Our analysis shows how a discourse of decommodification seems to underlie the strategies and practices implemented by farmers. It focuses on place-based developments to secure the autonomy of farmers and communities. We argue that, to safeguard the possession and use of land for agroecological farming in the future, both developments of land decommodification (long-term tenancy and commons) should be supported. This can be done by integrated policies on land sale and lease that align with the ecological carrying capacity and agroecological production capacity of land, and that ensure compensation for monetary downgrading of agricultural land.
Investigation of optical and electrical characteristics in photovoltaic devices colored by the functional metal oxide coatings
Authors:   , Rudzikas Matas
Published: June 2024

As solar energy continues to advance, it is accompanied by decreasing surface availability and its increasing costs, and alongside a seek of energy independence this drives an increasing demand for building-integrated photovoltaics. However, its expansion faces limitations due to the dominant PV colors in the market being blue or black, often not fitting with architectural ideas. Therefore, in this work cost-effective methodologies applying functional metal oxides for modification of solar cell color were analyzed, employing combined simulations with experiments while using commercial solar cells as a baseline. The simplest approach was deposition of ITO as a part of double layer anti-reflective coating on the top of the commercial silicon solar cell. It was proved that variation of ITO thickness from 0 to 240 nm allows modification of color from blue to brown resulting in relatively low current density loss up to 8%. Lower refractive index (1.8 at 632 nm) resulted in lower, blue-shifted and narrower reflection peaks in the surface reflection spectrum compared to a higher refractive index (2.07 at 632 nm). In the second part, Bragg reflector structure was optimized and then experimentally demonstrated using cheap sol-gel technique with only a 3 layered structure (TiO2/SiO2/TiO2), having 2-3 times higher color brightness compared to colored panels with commercial solar cells. Finally, coloring of kesterite/silicon 2 terminal tandem structures was investigated through digital modelling. The study revealed that ARC thickness variation of Al2O3 from 0 to 300 nm allows modification of color with an efficiency loss of less than 2% (relative) with color purity being low and hues restricted to brownish and purplish.

Shelters in coal mines are used to protect miners during accidents associated with gassing of roadways, fires, explosions of methane-air mixture. Supporting of the shelter must provide the necessary level of tightness to prevent the penetration of noxious gases from the mine atmosphere or gas-bearing rocks. The purpose of this work is to study the possibility of noxious gases penetration into a shelter in case of its sealing failure for the early detection of weak constructional elements and to ensure safe conditions for people in the shelter during accidents. To achieve the goal, methods of numerical simulation of time-dependent processes of elastic-plastic deformation and gas filtration were used. A coal-rock mass with a roadway and an adjacent shelter with typical supporting elements were considered at a depth of 400 m and 1000 m. The study of the stress state of the shelter support showed that under the considered conditions, in the case of a relatively small depth, hard steel and concrete constructional elements withstand the load without loss of their stability. With an increase in the depth of the shelter location, inelastic deformation of the concrete barrier between the shelter and the roadway occurs on a small area. The probable destruction of this zone will not lead to a violation of the entire barrier integrity, which makes it impossible to start mass exchange processes between clean air in the shelter and harmful combustion products in the roadway. The roof and walls of the shelter, covered with reinforced concrete and sealed, remain practically impermeable from the next day after their construction in both the first and second cases. But later, in the lower left corner of the shelter at a depth of 1000 m, methane from the coal seam begins infiltrating through the unsupported and unsealed floor. The developed numerical model can be used with other basic data on mining and geological conditions to identify constructional elements of a shelter, which lose stability during operation and threaten the shelter's tightness. Timely strengthening of such weak elements will prevent the danger of noxious gases infiltrating into the shelter. Keywords: time-dependent rock deformation, shelter, sealing failure, gas filtration, numerical simulation.
The Path to Labor Stability for Young Spanish Workers during the Great Recession
Authors: Moreno Raymundo Gloria , Cebrián López Inmaculada
Published: June 2024

The Great Recession (2008-2013) worsened the labor market position of young Spaniards. despite governments launched labor market reforms in 2010 y 2012 to improve labor stability, permanent employment accounted for only 10 percent of total new contracts. This paper tries to disentangle which factors are hindering the promotion of open-ended contracts to stabilize Spanish young workers into permanent employment. These analysis use panel data from the MCVL (Muestra Continua de Vidas Laborales). The results indicate that, although having an open-ended contract increases the probability of being employed after two years, only 50 percent of these initial contracts survive. The structure of labor demand explains this instability.

Aims: this study aimed to evaluate the effectiveness of a Theory of Reasoned Action (TRA) – based educational program in promoting physical activity (PA) behavior in Chronic low back pain (cLBP) patients. Methods: the Reasoned Action Theory-based Back Care program was a randomized controlled trial conducted at a Health Service Center. It compared the TRA construct’s effectiveness against a control group. Eighty patients referred to Shahid Beheshti University of Medical Sciences in Tehran were randomly assigned to either the TRA-based intervention group (n=40) or the control group (n=40). Both groups completed self-reported questionnaires at baseline, 3-month, and 6-month follow-ups. Additionally, a checklist was used to assess lumbar spine range of motion test skills using the modified Schober test. Results: a significant interaction effect was observed between “group” and “test time” factors (p<0.001). A total of 77 cLBP patients were evaluated, with a mean age of 41.0±4.2 years in the intervention group and 39.0±3.5 years in the control group. While both groups initially aligned with TRA constructs (p>0.05), the intervention group demonstrated significant improvements in PA-related behavior at both 3-month (p
<0.001) and 6-month (p><0.001) follow-ups. The mean score for PA behavior in the intervention group (8.4 ± 1.1) was significantly higher compared to the control group (3.2±1.0) (p><0.001). Similarly, pain intensity was significantly lower in the intervention group (3.8±2.2) compared to the control group (4.3±3.0) (p><0.001). Furthermore, the intervention group showed a significant improvement in lumbar spine range of motion test skills (p><0.05). The lumbar spine range of motion test skills of the intervention group significantly decreased (p><0.05). Conclusions: the TRA-BAC program demonstrates promise in improving PA-related behavior and reducing pain in cLBP patients through targeted educational strategies based on the TRA framework.
