Photocatalytic degradation plays a crucial role in wastewater treatment, and the key to achieving high efficiency is to develop photocatalytic systems that possess excellent light absorption, carrier separation efficiency, and surface-active sites. Among various photocatalytic systems, S-type heterojunctions have shown remarkable potential for efficient degradation. This work delves into the construction of S-type heterojunctions of ternary indium metal sulfide and bismuth ferrite nanofibers with the introduction of sulfur vacancy defects and morphology modifications to enhance the photocatalytic degradation performance. Through the impregnation method, BiFeO3/ZnIn2S4 heterojunction materials were synthesized and optimized. The 30% BiFeO3/ZnIn2S4 heterojunction exhibited superior photocatalytic performance with higher sulfur vacancy concentration than ZnIn2S4. The in-situ XPS results demonstrate that the electrons between ZnIn2S4 and BFO are transferred via the S-Scheme, and after modification, ZnIn2S4 has a more favorable surface morphology for electron transport, and its flower-like structure interacts with the nanofibers of BFO, which has a further enhancement of the reaction efficiency for degrading pollutants. This exceptional material demonstrated a remarkable 99% degradation of Evans blue within 45 min and a significant 68% degradation of ciprofloxacin within 90 min. This work provides a feasible idea for developing photocatalysts to deal with the problem of polluted water resources under practical conditions.

In this paper, LixCa(1−x)Cu3Ti4O12 (LCCTO) solid solutions were successfully synthesized. XRD diagrams showed that dopant acceptor Li+ cations, in a concentration range of x = 0.01–0.10, were successfully merged into CCTO structure. It was found that doping with low concentrations of lithium (x < 0.05) inhibited grain growth during annealing; however, for x > 0.05, the grain growth process resumed. Permittivity and dielectric losses of obtained LCCTO ceramics were analyzed by the means of impedance spectroscopy in a frequency range from 10−1 to 106 Hz. It was revealed that acceptor doping with lithium at an appropriate concentration of x = 0.05 allowed to obtain ceramics with a permittivity level of ε′ = 3 × 104 and low dielectric losses tanδ < 0.1 at 1 kHz. Further addition of lithium in a concentration range of x = 0.075–0.10 led to a sharp decline in permittivity and an increase in dielectric losses. It was discovered that lithium addition to CCTO ceramics drastically decreased grain boundary resistivity from 115 MΩ·cm to 5–40 MΩ·cm at x = 0.01–0.10. Using Havriliak–Negami equation, the relaxation times for grain dipoles and grain boundary dipoles were found to be ranging from 0.8 × 10−6 to 1.7 × 10−6 s and from 0.4 × 10−4 to 7.1 × 10−4 s, respectively. The developed materials can be used in the manufacture of Multilayer Ceramic Capacitors (MLCC) as a dielectric.

Published: July 2023

Given the recognized advantages of additive manufacturing (AM) printing systems in comparison with conventional subtractive manufacturing systems, AM technology has become increasingly adopted in 3D manufacturing, with usage rates increasing dramatically. This strong growth has had a significant and direct impact not only on energy consumption but also on manufacturing time, which in turn has generated significant costs. As a result, this problem has attracted the attention of industry actors and the research community, and several studies have focused on predicting and reducing energy consumption and additive manufacturing time, which has become one of the main objectives of research in this field. However, there is no effective model yet for predicting and optimizing energy consumption and printing time in a fused deposition modeling (FDM) process while taking into account the correct part orientation that minimizes both of these costs. In this paper, a neural-network-based model has been proposed to solve this problem using experimental data from isovolumetrically shaped mechanical parts. The data will serve as the basis for proposing the appropriate model using a specific methodology based on five performance criteria with the following statistical values: R2-squared > 99%, explained variance > 99%, MAE < 0.99%, MSE < 0.02% and RMSE < 1.36%. These values show just how effective the proposed model will be in estimating energy consumption and FDM printing time, taking into account the best choice of part orientation for the lowest cost. This model provides a global understanding of the primary energy and time requirements for manufacturing while also improving the system’s cost efficiency. The results of this work can be extended and applied to other additive manufacturing processes in future work.

Published: July 2023

Cysteine-rich secretory proteins (C), antigen 5 (A), and pathogenesis-related 1 proteins (P) comprise widespread CAP superfamily proteins, which have been proven to be novel virulence factors of mammalian pathogenic fungi and some plant pathogens. Despite this, the identification and function of CAP proteins in more species of plant pathogens still need to be studied. This work presents the identification and functional analysis of CAP superfamily proteins from Puccinia striiformis f. sp. tritici (Pst), an important fungal pathogen that causes wheat stripe rust on wheat worldwide. A total of six CAP genes were identified in the Pst genome, designated as PsCAP1–PsCAP6. Five PsCAP proteins, including PsCAP1, PsCAP2, PsCAP3, PsCAP4, and PsCAP5, have N-terminal signal peptides secreted with the yeast signal sequence trap assay. Single-nucleotide polymorphism (SNP) analysis indicated that they showed a low level of intraspecies polymorphism. The expression abundance of PsCAP genes at different Pst infection stages was detected by RT-qPCR, and most of them were highly expressed during Pst infection on wheat and also Pst sexual reproduction on barberry (Berberis shensiana). Noticeably, the silencing of these six PsCAP genes by BSMV-mediated HIGS indicated that PsCAP1, PsCAP4, and PsCAP5 contribute significantly to Pst infection in wheat. These results indicate that PsCAP proteins may act as virulence factors during Pst infection, which also provides insights into Pst pathogenicity.
Phosphorylation of Ack1 by the Receptor Tyrosine Kinase Mer
Authors: Hayashi Samantha Y. , Craddock Barbara P. , Miller W. Todd
Published: July 2023

Ack1 is a nonreceptor tyrosine kinase that is associated with cellular proliferation and survival. The receptor tyrosine kinase Mer, a member of the TAM family of receptors, has previously been reported to be an upstream activator of Ack1 kinase. The mechanism linking the two kinases, however, has not been investigated. We confirmed that Ack1 and Mer interact by co-immunoprecipitation experiments and found that Mer expression led to increased Ack1 activity. The effect on Ack1 was dependent on the kinase activity of Mer, whereas mutation of the Mer C-terminal tyrosines Y867 and Y924 did not significantly decrease the ability of Mer to activate Ack1. Ack1 possesses a Mig6 Homology Region (MHR) that contains adjacent regulatory tyrosines (Y859 and Y860). Using synthetic peptides, we showed that Mer preferentially binds and phosphorylates the MHR sequence containing phosphorylated pY860, as compared to the pY859 sequence. This suggested the possibility of sequential phosphorylation within the MHR of Ack1, as has been observed previously for other kinases. In cells co-expressing Mer and Ack1 MHR mutants, the Y859F mutant had higher activity than the Y860F mutant, consistent with this model. The interaction between Mer and Ack1 could play a role in immune cell signaling in normal physiology and could also contribute to the hyperactivation of Ack1 in prostate cancer and other tumors.

Published: July 2023

Modern lifestyles have led to sedentary behavior, lower participation in active movement and physical activities during leisure time, unhealthy diets, and increased exposure to stress. It is important to examine the interaction of several lifestyle risk factors instead of focusing on one alone. The purpose of this study was to identify lifestyle patterns in a group of patients with type 2 diabetes and the associations of its components with certain metabolic parameters. Using principal component analysis, we identified three dietary patterns: the prudent pattern (fat, oil, cereals, potatoes, vegetables, fish, nuts, seeds and fruits), the Western pattern (meat and meat products, eggs and soft drinks) and the traditional pattern (milk and its derivatives, soups and sauces, with a low intake of sugar/snacks). In addition, using the same method of analysis, we identified two lifestyle patterns: the inadequate lifestyle pattern (Western dietary pattern, increased hours of sleep and lower levels of stress) and the traditional lifestyle pattern (traditional dietary pattern, increased physical activity (PA) and non-smoking status). The inadequate lifestyle pattern was associated with younger age, hypertension and diabetic neuropathy. The traditional lifestyle pattern was related to lower postprandial blood glucose levels. Sedentary individuals were more likely to be over 65 years old and to have higher glycated hemoglobin (HbA1c). Smokers were also more likely to have inadequate glycemic and lipid profile control.
Systematic Study of Paeonol/Madecassoside Co-Delivery Nanoemulsion Transdermal Delivery System for Enhancing Barrier Repair and Anti-Inflammatory Efficacy

Published: July 2023

Sensitive skin is defined as skin with low tolerance and high reactivity. Natural products, such as paeoniflorin and madecassoside, have unique skin care functionality. However, because they are hampered by the skin barrier, paeoniflorin and madecassoside have difficulty penetrating the stratum corneum, resulting in weakened skin barrier repair and anti-inflammatory effects. In addition, there is a lack of detailed studies on the efficacy of paeonol and madecassic in human skin, especially in 3D skin models and clinical trials. To overcome the low transdermal delivery issue, we developed nanoemulsions (PM-NEs) loaded with paeonol and madecassoside to improve their delivery efficiency and promote sensitive skin repair and anti-inflammation effects. Furthermore, systematic evaluations of the efficacy in cell line models, 3D skin models, and clinical trials were conducted. The PM-NEs effectively improved the efficacy of paeonol and madecassoside glucoside transdermal penetration and retention and enhanced cellular uptake. Cellular assays and 3D epidermal models showed that the PM-NEs significantly promoted the secretion of filamentous protein, aquaporin 3, Claudin-1, and hyaluronic acid, and considerably inhibited the secretion of interleukin 1α, interleukin 6, tumor necrosis factor-α, and prostaglandin E2 compared to free components. Notably, clinical trial data showed that the PM-NEs significantly reduced transepidermal water loss, a* values, erythropoietin, the amount of non-inflammatory acne, and the amount of inflammatory acne in the facial skin. Three levels of systematic studies suggest that co-delivery of paeoniflorin and madecassoside via nanoemulsions is a promising strategy to improve topical delivery efficiency and anti-inflammatory repair efficacy in sensitive skin.

Published: July 2023

Ulcerative colitis (UC) is an inflammatory bowel disease (IBD), and its pathogenesis is related to intestinal mucosal barrier damage and gut microbiota imbalance. Protopine (PRO), an isoquinoline alkaloid, is one of the main anti-inflammatory ingredients of traditional Chinese medicine Macleaya cordata (Willd.) R. Br. This study investigated the effects of PRO on the intestinal mucosal barrier and gut microbiota in dextran sodium sulfate (DSS)-induced colitis mice. C57BL/6J mice were treated with 3% DSS in drinking water to induce acute colitis, while PRO was administered orally once daily for 7 days. The results showed that PRO administration significantly alleviated the symptoms of DSS-induced colitis in mice and inhibited the expression of inflammation-related genes. In addition, PRO restored the integrity of the intestinal barrier in colitis mice by restoring colonic mucin secretion and promoting the expression of tight junction proteins. Furthermore, PRO alleviated the DSS-induced gut microbiota dysbiosis by decreasing the abundance of Proteobacteria, Escherichia-Shigella and Enterococcus, as well as enhancing the abundance of beneficial bacteria, such as Firmicutes and Akkermansia. These findings suggested that PRO effectively alleviated DSS-induced ulcerative colitis by suppressing the expression of inflammation-related genes, maintaining the intestinal mucosal barrier and regulating the intestinal microbiota.
Understanding the Molecular Mechanism of Thermal and LA-Catalysed Diels–Alder Reactions between Cyclopentadiene and Isopropyl 3-Nitroprop-2-Enate
Authors: Dresler Ewa , Wróblewska Aneta , Jasiński Radomir
Published: July 2023

The molecular mechanism of the Diels–Alder reaction with the participation of cyclopentadiene and isopropyl 3-nitroprop-2-enate was examined based on wb97xd/6-311+G(d) (PCM) quantum chemical calculations. It was found that the type of mechanism for the conversion of addends depends significantly on the reaction conditions. In less-polar environments, a one-step polar mechanism is realised. In more polar solvents, the formation of “extended”-type zwitterionic intermediates is possible. In contrast, in the presence of an LA-type catalyst, the one-step mechanisms are replaced by respective stepwise mechanisms with zwitterionic or heterocyclic intermediates.

Published: July 2023

Dicofol is a highly toxic residual pesticide in tea, which seriously endangers human health. A method for detecting dicofol in tea by combining stoichiometry with surface-enhanced Raman spectroscopy (SERS) technology was proposed in this study. AuNPs were prepared, and silver shells were grown on the surface of AuNPs to obtain core–shell Au@AgNPs. Then, the core–shell Au@AgNPs were attached to the surface of a PDMS membrane by physical deposition to obtain a Au@AgNPs/PDMS substrate. The limit of detection (LOD) of this substrate for 4-ATP is as low as 0.28 × 10−11 mol/L, and the LOD of dicofol in tea is 0.32 ng/kg, showing high sensitivity. By comparing the modeling effects of preprocessing and variable selection algorithms, it is concluded that the modeling effect of Savitzky–Golay combined with competitive adaptive reweighted sampling–partial least squares regression is the best (Rp = 0.9964, RPD = 10.6145). SERS technology combined with stoichiometry is expected to rapidly detect dicofol in tea without labels.

Published: July 2023

As the foremost category of carbon materials, carbon dots (CDs) have been extensively applied in many domains because of their special fluorescence features and outstanding biocompatibility. However, in early studies of fluorescent CDs, as the fluorescence wavelength of most CDs was restricted to the blue or green region and was excitation dependent, the application of CDs was limited. In this study, three representative CDs, fluorescing yellow, green, and blue, were synthesized under alkaline, neutral, and acidic circumstances, respectively, while using a hydrothermal method in which catechol and phthalaldehyde acted as carbon sources and methanol functioned as the reaction solvent. The carbon nuclei of the three fluorescent CDs all had comparable graphite structures. The diversity of photoluminescence (PL) emission from these three CDs was attributed mainly to the different sizes of the sp2 conjugated structures among them. Mixing synthesized CDs with epoxy resin, three colors (yellow, green, and blue) of LED using CIE coordinates (0.40, 0.44), (0.33, 0.46), and (0.21, 0.22), respectively, were successfully prepared.
Solving ill-posed Helmholtz problems with physics-informed neural networks
Authors: Nechita Mihai
Published: July 2023

We consider the unique continuation (data assimilation) problem for the Helmholtz equation and study its numerical approximation based on physics-informed neural networks (PINNs). Exploiting the conditional stability of the problem, we first give a bound on the generalization error of PINNs. We then present numerical experiments in 2d for different frequencies and for geometric configurations with different stability bounds for the continuation problem. The results show that vanilla PINNs provide good approximations even for noisy data in configurations with robust stability (both low and moderate frequencies), but may struggle otherwise. This indicates that more sophisticated techniques are needed to obtain PINNs that are frequency-robust for inverse problems subject to the Helmholtz equation.

The Rise of Hybrid Practice
Authors: Whitaker Amy
Published: July 2023

This paper redefines hybrid practice as a form of creative institutional design rooted in the problems of dealing with multiple forms of value, an area in which the arts offer pioneering cases for general theory-building around external amalgamation of existing legal forms, internal design within hybrid legal forms, and field-building across communities and economic systems. Informed by, but distinct from, implicitly neoliberal and social-impact literatures on institutional entrepreneurship, hybridity, and agency, this framework extends theories of effectuation to argue for a view of arts entrepreneurship as a laboratory for complex problem-solving both within and well beyond the arts.

Bailarinas decimonónicas en llamas: un ensayo sobre peligros reales e incineraciones metafóricas
Authors: González Ignacio
Published: July 2023

A partir de ciertos casos de accidentes de bailarinas ocurridos a mediados del siglo XIX y mencionados en la llamada historia de la danza escénica occidental, este ensayo intentará reflexionar sobre lo que esos accidentes revelaban. Se planteará que no solo estos accidentes invertían la imagen ideal de la bailarina neoclásica romántica al poner en primer plano su lugar como mujeres trabajadoras, sino además que estos accidentes intensificaban, en la audiencia, la experiencia de lo sublime. En ese sentido, se intentará vislumbrar también otros peligros (políticos y/o morales) con los cuales se asociaba la profesión y que tenían como centro los cuerpos de estas jóvenes mujeres del siglo XIX que —literal o metafóricamente— vivían para (y morían por) moverse en escena.

Flowing water can be used as an energy source for generators, providing a major part of the energy for daily life. However, water is rarely used for information or electronic devices. Herein, we present the feasibility of a polarized liquid-triggered photodetector in which polarized water is sandwiched between graphene and a semiconductor. Due to the polarization and depolarization processes of water molecules driven by photogenerated carriers, a photo-sensitive current can be repeatedly produced, resulting in a high-performance photodetector. The response wavelength of the photodetector can be fine-tuned as a result of the free choice of semiconductors as there is no requirement of lattice match between graphene and the semiconductors. Under zero voltage bias, the responsivity and specific detectivity of Gr/NaCl (0.5 M)W/N-GaN reach values of 130.7 mA/W and 2.3 × 10

Jones under 350 nm illumination, respectively. Meanwhile, using a polar liquid photodetector can successfully read the photoplethysmography signals to produce accurate oxygen blood saturation and heart rate. Compared with the commercial pulse oximetry sensor, the average errors of oxygen saturation and heart rate in the designed photoplethysmography sensor are ~1.9% and ~2.1%, respectively. This study reveals that water can be used as a high-performance photodetector in informative industries.

Strawberries are horticultural crops that can grow well in subtropical regions. Strawberries require cool environmental conditions with temperatures between 17°C-20°C and humidity between 80% -90%. Cultivating strawberries in the tropics is a challenge in itself because of the temperature and humidity in this area. One way to cultivate strawberry plants in the tropics is to use a Green House. Green House is designed to maintain the temperature and humidity according to the needs of the strawberry plants. This study aims to create a system monitoring and controlling greenhouses using the internet of things. Users can monitor and control the condition of the Green House via an Android smartphone with the Blynk application. When the air temperature and humidity values are in the Green House, the system will work to readjust the temperature and humidity in the Green House. This system uses ESP32 as the control center and a DHT22 sensor to measure air temperature and humidity. Based on the results of the design and performance analysis of the tool, the accuracy of the air temperature gauge is 99.52% and the air humidity is 99.29%. The system successfully controlled the temperature and humidity in the Green House room for 23 days of testing.

ABSTRACT

The existence of the Covic-19 pandemic also affects the economic factors of the community that interfere with the immune system, so there is a need for productive activities that can increase added value. Banana peel utilization technology aims to train the community in dealing with plant waste management. This community service activity was carried out in Ngade Village, South Ternate District, Ternate City Regency. The target of the service participants is a group of young people who are members of the productive economic group "Qonita". The method used is the indirect method and the learning by doing method by demonstrating and conducting counseling about the manufacture of organic fertilizer made from banana peels. The activities provided include counseling and training on making organic fertilizer from banana peels. All activities are carried out online and offline while still implementing the Covic-19 protocol. To find out the increase in understanding of the partner group, an evaluation was designed at the beginning (pre test) and at the end of the activity (post test). From the pre-test and post-test scores, the results of the implementation of this activity showed that the insight ability of the "Qonita" youth group increased by 81.6%. The socialization of making organic fertilizer made from banana peels provides additional insight for the youth group "Qonita" in utilizing agricultural waste.

Abstract

The Sion Farmers Group is one of the groups that cultivate four species of citrus, namely Soe Mandarin, hikson oranges, Siamese oranges, and limes.  Various species of pests and dieases that affect the growth and development of citrus include Phytopthora sp., Diplodia sp., Triteza virus, Scirtotfrips citri, Diaporina citri and fruit flies.  Another problem faced by parteners is not providing fertilizer for plants. This community partnership program aims to guide, foster, and empower farmers to manage environmentally friendly citrus pests using biological fertilizers and biopesticides. Answering farmers’ problems, the methods used are counseling and training, adoption and introduction of technology (demonstrations and experiments on the applications of cheap and economical technology as well as environmentally friendly); and emprowerment of farmer group members through mentoring and evaluation by the implementing team. The results of the implementation showed that as many as 40% of farmer group members knew the species of pests and diaseases in citrus, 70% of group members could make tricocompost biofertilizer, liquid organic fertilizer, and botanical pesticides. As many as 60% of farmers apply tricocompost on citrus plants and several other species of plants such as chili.

Abstrak  

Aktivitas sekolah membutuhkan zat gizi yang cukup, dan anak dapat memperolehnya di sekolah melalui jajan di sekolah dan makan siang di sekolah. Pilihan menu dan jenis jajanan sangat bervariasi, dan keamanan pangan mungkin saja tidak dapat di kontrol. Sebagai konsumen, anak perlu dibekali pengetahuan tentang jajanan yang sehat. Dengan demikian, anak-anak perlu diberikan pengetahuan tentang 3J, yaitu jenis, jadwal dan jumlah makanan yang sesuai untuk kebutuhan anak,  serta syarat jajanan yang sehat. Kegiatan ini dilakukan dengan menggunakan metode penyuluhan, yang juga dilengkapi dengan model kompetisi. Kompetisi untuk membawakan materi tentang 3J dan jajanan sehat dilakukan oleh anak-anak sebagai peserta kegiatan. Hal ini dilakukan agar pesan yang diberikan pada anak akan selalu diingat. Dengan metode ini juga, anak-anak dapat menjadi sumber informasi pengetahuan  tentang 3J dan jajanan yang sehat. Selain pengetahuan anak meningkat, anak juga menjadi lebih percaya diri dalam berkomunikasi di depan banyak orang.

Abstract  

School activities require sufficient nutrients, and children can get them at school through snacks at school and lunch at school. Menu choices and types of snacks vary widely, and food safety may not be controlled. As consumers, children need to be equipped with knowledge about healthy snacks. Thus, children need to be given knowledge about the 3Js, namely the type, schedule and amount of food that is appropriate for the child's needs, as well as the requirements for healthy snacks. This activity is carried out using the extension method, which is also equipped with a competition model. The competition to bring material about 3J and healthy snacks was carried out by children as participants in the activity. This is done so that the message given to the child will always be remembered. With this method, children can be a source of information about 3J's and healthy snacks. In addition to increasing children's knowledge, children also become more confident in communicating in front of many people..

High stakes assessments in primary schools and teachers’ anxiety about work
Authors: Jerrim John , Sims Sam , Allen Rebecca
Published: July 2023

High-stakes assessments – where the results have important consequences for teachers, pupils and/or schools – are a common feature of many education systems across the world. One argument often made against their use, however, is that they have a negative impact on welling across the education sector. This includes those teachers who hold most responsibility for the results. We present new evidence on this matter by examining how the Year 6 Statutory Assessment Tests (SATs) conducted in England’s primary schools are linked to how anxious teachers feel about work. Drawing on unique panel data from around 1,000 primary school teachers, we illustrate how the SATs are associated with a short, sharp shock to teachers’ anxiety levels during the week the tests take place. Yet there is little evidence that those most exposed to the pressures of SATs suffer from especially prolonged periods of high anxiety levels. We thus conclude that, although there may be other reasons to lower the stakes attached to primary school assessments, the benefits for teachers’ anxiety levels are likely to be marginal.

Authors: Rodríguez Tuesta Betty
Published: July 2023

El objetivo de este artículo es analizar los conceptos de redacción académica, enfoque por competencias, enseñanza superior; pensamiento complejo desde la visión universitaria, con la finalidad de comprender cuales son las implicancias de la redacción académica en el nivel superior, en qué consiste la alfabetización académica y cuáles son los retos y desafíos de la redacción académica superior  a partir del enfoque por competencias.El objetivo es poner a disposición del personal docente universitario  las implicaciones de estos constructos en la redacción académica. La metodología utilizada consistió en la revisión narrativa con una estrategia de búsqueda según el tema, autores, a partir de la revisión minuciosa de 40 artículos académicos en idioma inglés con bibliografía actualizada disponible en revistas indexadas. El análisis realizado permite concluir que la redacción académica desde el enfoque por competencias es fundamental para el desempeño académico y profesional dentro y fuera de la universidad. Para lograr dichos procesos de escritura académica es necesario que la escritura en la universidad sea una prioridad en todas las áreas del conocimiento durante todo el proceso formativo del estudiante. Por tanto, urge avanzar en una visión más interdisciplinar e integral de la lectura y la escritura respetando los procesos para lograr resultados eficaces.

Selama beroperasi, setiap pesawat terbang pasti memiliki jadwal untuk pemeliharaan, salah satu bentuk perawatan pesawat terbang adalah dengan pengecatan. Pengecatan adalah cara yang umum digunakan untuk mencegah kerusakan yang disebabkan oleh korosi. Biasanya warna cat akan memudar akibat terpapar suhu yang panas dan dingin. Melihat pernyataan tersebut maka suatu cat harus memiliki sifat dapat memperkuat (re)inforcing permukaan benda yang di cat. Untuk mendapatkan hasil yang baik dalam sebuah cat dipengaruhi oleh campuran resin, thinner, dan cat. Penelitian ini bertujuan untuk mengetahui pengaruh nilai campuran resin dan cat terhadap temperatur cuaca panas dan dingin. Dalam penelitian ini akan dilakukan perbandingan cat dan thiner dengan resin menggunakan nilai perbandingan cat dan thiner 1:1 dan nilai resin 20%, 40%, dan 60% yang akan dilakukan pada spesimen dari bahan aluminium. Setelah melakukan pengujian ketahanan cat dengan campuran variasi nilai resin pada perubahan temperatur cuaca panas dan dingin menggunakan alat oven dengan suhu 100°C dan freezer dengan suhu -0,2°C diketahui bahwa semakin banyak penambahan nilai campuran resin yang berlebihan dapat menyebabkan cat susah mengering dan tidak dapat mengering dengan sempurna yang disebabkan karena semakin tebalnya lapisan cat yang dihasilkan oleh penambahan nilai resin, pencampuran nilai resin yang berlebihan juga menyebabkan pengaruh cacat pada lapisan cat seperti cacat bintik, cacat leleh, dan warna yang menurun atau memudar pada saat terkena perubahan suhu dari temperatur panas ke temperatur dingin. Dapat disimpulkan bahwa penambahan campuran nilai resin yang berlebihan tidak baik untuk ketahanan cat dan untuk menghasilkan kualitas cat yang baik adalah dengan tidak menambahkan campura nilai resin.
