Abstract. A multimethod approach aimed at characterizing carbonate parietal deposits and at proposing a chronology for these carbonate crusts is described. Dating was performed by radiometric methods (C-14 for recent samples and U series) on samples that had been characterized beforehand using optical and cathodoluminescence microscopy and Fourier transform infrared microspectroscopy. For the U series, high precision on U–Th ages was achieved using liquid phase multicollector inductively coupled plasma mass spectrometry (ICP-MS) applied to large samples, while laser ablation single collector inductively coupled plasma sector field mass spectrometry (ICP-SFMS) provided information on the reliability of the sampling with a high spatial resolution. This methodology, based on the combination of these two techniques reinforced by the information obtained by the calcite characterization methods, was applied to carbonate deposits from the cave of Trou du Renard (Soyons, France). The ages obtained with the two U–Th dating techniques are comparable and illustrate that different laminae were deposited at different rates in the samples. In the future, this procedure, based on the mineralogical and geochemical characterization of the samples and their dating by radiometric methods, will be applied to the layers of parietal carbonates deposited on Palaeolithic decorated walls. When the crystallization is slow, the U/Th dating method by imaging technique is of interest, as well as that by multicollector ICP-MS in liquid phase. The development of robust dating methods on very small quantities of material will make it possible to define the chronological framework of cave rock art.

Abstract. Predicting the response of hydrologic systems to modified driving forces beyond patterns that have occurred in the past is of high importance for estimating climate change impacts or the effect of management measures. This kind of prediction requires a model, but the impossibility of testing such predictions against observed data makes it difficult to estimate their reliability. Metamorphic testing offers a methodology for assessing models beyond validation with real data. It consists of defining input changes for which the expected responses are assumed to be known, at least qualitatively, and testing model behavior for consistency with these expectations. To increase the gain of information and reduce the subjectivity of this approach, we extend this methodology to a multi-model approach and include a sensitivity analysis of the predictions to training or calibration options. This allows us to quantitatively analyze differences in predictions between different model structures and calibration options in addition to the qualitative test of the expectations. In our case study, we apply this approach to selected conceptual and machine learning hydrological models calibrated for basins from the CAMELS data set. Our results confirm the superiority of the machine learning models over the conceptual hydrologic models regarding the quality of fit during calibration and validation periods. However, we also find that the response of machine learning models to modified inputs can deviate from the expectations and the magnitude, and even the sign of the response can depend on the training data. In addition, even in cases in which all models passed the metamorphic test, there are cases in which the quantitative response is different for different model structures. This demonstrates the importance of this kind of testing beyond and in addition to the usual calibration–validation analysis to identify potential problems and stimulate the development of improved models.

The absence of habitat-based guidance for wetland managers on the British mosquito assemblages has in recent years prevented development of the ecological aspect of medical entomology in the UK. This has been particularly relevant in the context of emerging mosquito-borne disease and the creation of wetlands for biodiversity and flood-alleviation goals. This study aimed to provide empirically derived habitat-based predictions in order to assess the suitability of English wetland habitats for mosquitoes. Entomological field data on mosquito density and diversity were collected at 12 English wetlands in 2017 and 2018 using immature and adult mosquito surveys. Wetlands were chosen representing a number of wetland categories that included coastal, urban, wet woodland and established freshwater wetlands to identify key species and functional groups to inform predictions of mosquitoes by aquatic habitat type. Nineteen species were recorded from eight functional groups, totalling 38,577 adult female (19 mosquito species groups) and ~2,000 immature mosquitoes in 13 aquatic habitat types. Approximately 90% of all trapped mosquitoes were attributed to one of five species groups. The most common species were: Aedes (Och.) caspius (Pallas, 1771) (~35% of all mosquitoes), associated with coastal estuarine and flooded grassland sites, Ae. cantans/annulipes (19.7%) in wet woodland field sites, Anopheles claviger (16.2%) and Coquillettidia richiardii (12.6%) with the widest occurrence, found in nearly all field sites, and Ae. detritus (6.9%) in brackish field sites. Across the study, adult mosquito activity increased from week 21 with wet woodland Aedes mosquitoes, until week 40 with open-flood water species, with greatest diversity of species during weeks 23–30. The resulting data inform efforts towards developing predictive tools for non-entomologists to accurately predict the presence and abundance of British mosquitoes in a given habitat, using local knowledge of seasonal aquatic habitats.

The principle of freedom of contract and corporate contract
Authors: Kaldybayev Askar
Published: June 2024

The agreement between the participants (shareholders) of the company as a corporate governance tool is widely used in foreign practice. In Kazakhstan, the corporate agreement is not yet fully used, although it can provide flexible and appropriate regulation between the participants of the company, between the participants and third parties, the company itself. This type of agreement is not named in the legislation. Domestic law enforcement officials, and especially judges, are wary of the new mechanisms for regulating corporate relations. A corporate agreement is usually understood as an agreement through which the participants of the company agree on actions to manage the company and ensure their interests within the framework of such management. Such an agreement is actively used to regulate corporate relations in many countries. The operation of the contract in the corporate environment and the greater number of peremptory norms does not mean that the principle of freedom of contract, including in terms of determining its content, has only partial application in relation to a corporate contract. And if so, then general restrictions on the freedom of contract apply to this agreement. Relying on freedom of contract and autonomy of will, company participants can include in their contract those provisions that they consider important and necessary to ensure and protect their rights and interests, to achieve their legitimate goals. But when establishing such provisions, the parties to the contract must take into account the restrictions that exist in the law to protect the public interests and the interests of persons in need of such protection.

Published: June 2024

La crisis socioecológica está generando nuevas formas de excusión social que está expulsando a muchas personas en todo el mundo hacia los márgenes de la sociedad, pero también provocan formas de resistencia popular para hacerle frente. El debate ecologista se centra en las políticas institucionales necesarias para frenar el colapso, pero no refleja ni la realidad actual de los excluidos ni su papel crecientemente organizado en los llamados “territorios de sacrificio” y en los “territorios de exclusión”. Esas experiencias, a las que llamo rebelión de los decrecidos están mostrado su capacidad de autoorganización y de incidencia política orientada hacia un cambio de sistema.

Published: June 2024

La pobreza en la infancia tiene un gran impacto negativo tanto en el presente de los niños/as que la sufren como en su futuro. Así que este estudio tiene como objetivo conocer las estrategias de supervivencia que utilizan los niños/as para poder afrontar la adversidad en un colectivo invisible: los niños/as de etnia gitana que sobreviven en un asentamiento chabolista donde las necesidades básicas no están cubiertas. Para ello, medimos su capacidad resiliente utilizando varios instrumentos (escala de resiliencia y entrevistas). Los resultados muestran que la cronicidad de la pobreza empeora la capacidad de resistencia, por lo que debemos evitar que estas situaciones se perpetúen en el tiempo.
Estigmatización y gestión neoliberal de la miseria. Por qué hablamos de pobreza y no de desigualdades
Authors: Sales Campos Albert
Published: June 2024

En las sociedades post-industriales, la pobreza y la marginalidad ya no pueden considerarse fenómenos cíclicos o coyunturales. Las sucesivas crisis capitalistas han dejado tras de sí un crecimiento de las formas extremas de precariedad y una reacción de los Estados basada en la estigmatización y la criminalización de los grupos sociales que quedan sistemáticamente al margen de los beneficios del crecimiento económico.
A través de algunos ejemplos, este artículo parte del “descubrimiento de las clases marginadas” en la época de los Estados del bienestar y de la construcción de la pobreza como objeto de intervención de las políticas públicas socialdemócratas para adentrarse, a través de algunos ejemplos en los discursos estigmatizadores que justifican las medidas de gestión neoliberal de la miseria.

The research aimed to identify latent mastitis in cows on farms in the Republic of Armenia by counting somatic cells in milk using the California method. Among the 170 animals examined, 60 had latent mastitis, which comprised 35.2 % of the population. The highest incidence was observed in the Vayoc Dzor region (50 %), while the lowest was found in the Sunik region (25 %). It was found that 40 animals (23.5 %) showed a pronounced reaction to mastitis, and the concentration of somatic cells in milk was 300-500 thousand/sm3 . 20 animals demonstrated a positive reaction to the test (11.7 %), and the number of somatic cells in milk exceeded 500 thousand/sm3. A microbiological study of milk from animals with subclinical mastitis was conducted to determine the species composition of pathogenic microflora. The study indicated that the milk was highly contaminated with staphylococcus, streptococcus, corynebacterial, E. coli, mycoplasma, candida, etc. A rise in leukocytes was observed in the blood of sick animals, as well as increases in band neutrophils, eosinophils, monocytes, lymphocytes, and ESRs. All this indicates, there is an inflammatory process present in the body and the immune system is mobilizing to fight pathology.

This article is dedicated to examining a bilateral project established between the Republic of Korea and Türkiye, with the overarching objective of elevating awareness and endowing preschool teachers with the capacity to embed education for sustainability (EfS) within their classroom practices seamlessly. For this purpose, a professional development (PD) program was developed regarding three pillars of sustainability and 7R themes. Fourteen preschool teachers attended the PD program. Three teachers participated in this case study to reveal teachers' transformation regarding sustainability and early childhood education for sustainability. The data were collected through pre-post-follow-up interviews and classroom observations. Thematic content analyses were conducted. According to the results, the PD program enhanced and deepened teachers’ sustainability knowledge. In addition, teachers could transfer the knowledge from the PD program on education for sustainability into their practice not entirely but acceptably, and they have a chance to reconsider their lifestyle habits regarding sustainability in many areas.
Stakeholder Engagement: Issues to Resolve for Sustainable Performance of Sugar Mills in Western Region, Kenya
Authors: W. W. Thomas , M. M. Stephen
Published: June 2024

The Kenyan sugar industry suffers from poor performance linked to corruption, mismanagement, reduced cane production, overreliance on imports and growing long maturing cane variety. These problems can be resolved by engagement of different stakeholders. This article is on stakeholder engagement and effect on sustainable performance in the sugar mills in western Kenya. The paper adopted the stakeholder theory, balanced scorecard model and human relations theory of management, as its theoretical framework. The descriptive research design was employed. The respondents included managers in the sugar mills, the permanently employed staff, government officials handling the industry in the region and representatives of cane farmers from the farmer blocs. Simple and stratified sampling technique was used and respondents filled the structured questionnaire from which descriptive, regression and correlation analyses were conducted. The findings revealed that respondents agreed that stakeholder relationship management increased sustainable performance of sugar mills. The correlation analysis results showed that stakeholder communication at (r =0.852), capacity building (r =0.551), stakeholder relationship management (r =0.742) and stakeholder control processes (r =0.641) were all closely associated with the dependent variable on sustainable performance. From the regression analysis, the results showed that 70.9% of change in sustainable performance in the sugar mills was influenced by stakeholder engagement. The beta coefficient results indicate that the four means of stakeholder engagement influenced performance of the sugar mills. The study concluded that aspects of stakeholder engagement improved performance as measured in terms of high-quality products, profit margin, sales volume and increased market share. It is recommended that the government as a key stakeholder of the sector should have policies to ban sugar free imports, enhance competencies of stakeholders through training, research on best cane variety and engage stakeholders to monitor and control activities in reducing corruption, mismanagement and misappropriation of resources. Engagement of stakeholders is important when seeking to grow and establish the industry.

Authors: Poohoi Ratchadakorn , Puntusavase Kanate , Ohmori Shunichi
Published: June 2024

Vehicle Routing Problem (VRP) is important in the transportation and logistics industries. Vehicle Routing Problem with Time Window (VRPTW) is a kind of VRP with the additional time windows constraint in the model and is classified as an NP-hard problem. In this study, we proposed Stas crossover in Genetic Algorithm (GA) to solve VRPTW by developing the problem with K-mean clustering. The experiments use the standard Solomon’s benchmark problem instances for VRPTW. The results with K-mean clustering are shown to perform better for minimum distance and average distance than without K-mean clustering. In the case of location and dispersion characteristics of the customer, the paths with K-mean clustering are arranged into groups and are orderly, but the paths without K-mean clustering are disordered. After that, this paper shows the comparison of the crossover operator performance on instances of Solomon benchmark, and appropriate crossover operators are recommended for each type of problem. The results of the proposed algorithm are better than the best-known solutions from the previous studies for some instances. Moreover, our proposed research will serve as a guideline for a real-world case study.
Design of Mathematical Model and Implementation of IoT Enabled Smart Secure Parking System
Authors: M.L.Keote
Published: June 2024

The fast growth of cities and the resulting rise in traffic have made it necessary to create effective parking control systems. This paper talks about how to build and set up an Internet of Things (IoT)-enabled smart parking system. IoT technology is used in the suggested system to solve problems with current parking systems, like wasteful use of space, traffic jams, and damage to the environment. A detailed mathematical model is created to find the best way to assign parking spaces, cut down on the time it takes to look for open spots, and improve the overall user experience. The system design combines different Internet of Things (IoT) parts, like sensors, motors, and communication units, so parking places can be managed and watched in real time. The math model includes methods for allocating parking spots dynamically based on data from IoT sensors gathered in real time. The goal of this model is to guess where parking spots will be available, make the best use of those places, and cut down on the time people spend looking for parking. The technology also uses machine learning to look at old data and get better at making predictions over time. Details about how to implement are talked about in depth, such as the hardware setup, transmission methods, and program parts. A lot of models and real-life tests in a city are used to judge the system's success. The results show big changes in how parking spaces are used, less traffic, and lower pollution, all of which make cities more sustainable. The suggested smart parking system that uses the Internet of Things (IoT) is a cost-effective and scalable answer to today's parking problems. More work will be done in the future to improve the system's abilities using advanced machine learning techniques and to spread its use to more cities. This study shows that IoT technology has the ability to change the way cities work and make life better in smart cities.
Embedding Hybrid Evolutionary Approach for Learning-to-Rank Computation for the Selection of Features Using Machine Learning
Authors: Sushilkumar Chavhan
Published: June 2024

Our study proposes a novel model for retrieving objects that utilizes learning-to-rank with L2 regularization. We employed an evolutionary-based simulated annealing technique to select the most informative features for our system and utilized a standardized regulation technique to handle the dropout of active features. Learning to rank is a well-researched area in machine learning and finds application in recommendation systems and search engines. Our study aims to introduce a new approach to feature selection for the learning-to-rank information retrieval model. By dropping inactive features and  maintaining  active  features,  we  can  improve the ranking function’s performance. We tested our proposed method on standard datasets and repeatedly improved the feature selection model of the LambdaMart algorithm. Empirical performance results show that our heuristic model provides better feature subset combinations, as measured by the NDCG, P@10, and MAP evolutionary metrics, than do baseline databases. Our proposed method surpasses existing learning-to-rank methods, paving the way for promising future research.
Mathematical Formulation of Deep Learning Model for Poultry Disease Classification using EfficientNet- B3 CNN Model
Authors: Ajay G. Barsagade
Published: June 2024

The agricultural industry, and particularly the poultry farming industry, is under pressure to increase output levels due to the growing human demand for animal products. There can be substantial economic losses and widespread chicken mortality as a consequence of an in-crease in infectious disease transmission caused by expanded poultry production. When compared to conventional ways for poultry disease identification, manual methods are time-consuming, labour-intensive, and error-prone. Also, experts' knowledge is usually necessary for making sense of the results. These restrictions raise the danger of the disease spreading across the flock and make it more difficult to diagnose diseases in a timely manner, both of which can have devastating effects. For a long time now, farmers have relied on specialists to identify and diagnose chicken illnesses. Consequently, many domesticated birds end up in the hands of farmers who suffer from either unreliable specialists or delayed diagnosis. The most prevalent chicken illnesses may be quickly recognised from pictures of chicken drop-pings using the techniques that are already accessible from artificial intelligence (AI) based on computer vision.In this paper, a deep learning approach offered that uses a pre-trained Convolution Neural Networks (CNN) model to determine which of the three categories best describes chicken excrement and offer a method for identifying and categorising poultry illnesses. The Effi-cientNet-B3 model was utilised in the development of the system. Coccidiosis, Salmonella, New Castle Disease and Healthy were the four health problems that were classified using the segmented picture by the deep learning model. The models were trained using standard benchmark database images of excrement from chickens. The outcomes of experiment demonstrate that the proposed method for identifying and categorizing chicken illnesses may accurately identify three prevalent poultry diseases. Consequently, this approach has the potential to be an invaluable resource for farm veterinarians and poultry producers.

高齡者在宅老化減少機構化照護環境設施的發展方向是世界各國共同的趨勢。我國住宅自有率高，老屋數量比例也高，對於高齡社會來說，老屋設施設備改善是促成「在地老化」的重要關鍵。本研究透過文獻回顧，彙整29項重要改善原則，利用問卷方式，採用因素分析歸納出二個主成分，並分析不同性別、年齡層、身分別對各改善原則重要性認知程度。發現涉及「可及性」及「安全性」之改善原則，普遍為各族群所重視。其中「可及的垂直動線設施」、「無高差的室內外動線」、「即時觸動的求救設備」、「防滑軟質的地板材質」4項最為重要。另外，女性對便利性中省力設施設備改善與男性有明顯的認知差距。29項改善原則，65歲以上族群重要性認知程度幾乎都高於未滿65歲族群，「無高差的室內外動線」、「可及的垂直動線設施」兩項重要程度容易被未滿65歲族群低估。建築師對「可及的垂直動線設施」的重要性明顯高於一般中高齡者，「居家照護的工作空間」則相反。主成份分析法篩檢出由高齡者居住環境改善的二組成份結果，初步得出成分一「空間便利舒適因素」10項重要改善原則，另外成分二「可及性及安全因素」7項重要改善原則，凸顯了「便利舒適性」與「可及安全」改善原則重要性。本研究結果可以提供政府作為鼓勵住宅改善推動重點的參考，也可以為建築從業者更容易理解與高齡者對於住宅改善的認知差距。It is a common trend for countries around the world to provide services for the elderly at home and in the community, and to reduce the development direction of institutionalization. Our country has a high rate of home ownership and a high proportion of old houses. For an aging society, the improvement of old house facilities and equipment is an important key to promoting ''Aging in place''. Through literature review, this study collected 29 important improvement items, used questionnaires, and adopted factor analysis to summarize four principal components, and analyzed the degree of awareness of the importance of each improvement principle in different genders, age groups, and identities. It was found that improvement items related to ''accessibility'' and ''safety'' are generally valued by all ethnic groups. Among them, ''accessible facilities on vertical flow '', ''indoor and outdoor flow’s floor without height difference'', ''instant emergency rescue equipment'', and ''non-slip and soft material floor'' are the most important. In addition, there is an cognitive difference between women and men in the improvement of labor-saving facilities and equipment in convenience. The awareness of the importance of various improvement projects among ethnic groups aged 65 and above is higher than that of those under 65 years old. The importance of the two items of ''accessible facilities on vertical flow ''and ''indoor and outdoor flow’s floor without height difference'' is easily underestimated by those under the age of 65, and the importance of ''accessible facilities on vertical flow'' for professional practitioners is significantly higher than that of the general middle-aged and elderly people, ''Workspace for homecare'' is the opposite. The results of this study can provide a reference for the government to encourage housing improvement to promote key projects, and can also help construction practitioners understand the cognitive difference in cognition of housing improvement with the elderly more easily.

A mononucleose infecciosa é uma doença causada pelo vírus Epstein-Barr que comumente acomete jovens e adultos, mas também pode acometer crianças. Caracterizada, principalmente, por febre, faringite e linfadenopatia. Apesar de ser uma doença frequente, o reconhecimento rápido dessa patologia nem sempre é fácil, entretanto, esse reconhecimento é importante para o tratamento adequado da doença, bem como para evitar a exposição a tratamentos ineficazes. O trabalho proposto apresenta um relato de caso sobre Mononucleose Infecciosa em um paciente de 4 anos e 3 meses, com edema palpebral bilateral, coriza por 5 dias e linfadenomegalia. Procurou atendimento, com administração de Penicilina G Benzatina e liberado após prescrição de sintomáticos. Sem melhora, procurou atendimento novamente, sendo encaminhado para um hospital universitário, onde foi internado e diagnosticado com Mononucleose Infecciosa. No presente estudo, foi realizada uma revisão da literatura acerca das apresentações, diagnóstico e tratamento dessa patologia, com o objetivo de enfatizar a relevância da investigação diagnóstica adequada para evitar tratamentos ineficazes, internação de alto custo e obter um bom curso da doença.

OBJETIVO: Identificar evidências científicas envolvendo avaliações dos residentes sobre o uso do ensino virtual nos programas de residência médica durante a pandemia da COVID-19, ressaltando pontos positivos e dificuldades. MÉTODOS: Revisão de escopo, selecionando artigos do período de março de 2020 a julho de 2023, que abordaram as perspectivas dos residentes sobre o ensino a distância na residência médica durante a pandemia e excluídas editoriais e artigos apenas sobre organização e estruturação das atividades do serviço. Foi utilizado o Portal Regional da Biblioteca Virtual em Saúde (BVS) para busca em pesquisa avançada, com as palavras-chave Educação a Distância; COVID-19; Internato e Residência. Foram selecionadas as bases de dados MEDLINE, LILACS e IBECS. RESULTADOS: Dos 134 artigos identificados, 34 foram selecionados e o maior número envolveu residentes de cirurgia. Dentre as múltiplas técnicas de aprendizado virtuais, as conferências e as aulas on-line foram as mais utilizadas. Os benefícios incluíram: mais atividades de pesquisa, maior flexibilidade e economia de tempo, melhor acessibilidade, baixo custo/maior efetividade, aumento da frequência às atividades, maior alcance de público, e redução de ansiedade. As percepções negativas foram dificuldades nos aspectos técnicos, menor engajamento real dos participantes, menor interação entre os profissionais, dificuldade em equilibrar a vida familiar, a falta do exame físico e da prática cirúrgica. CONCLUSÃO: Aspectos positivos predominaram sugerindo uma nova organização da residência médica que inclua o ensino virtual incorporado à prática. Para um ensino/aprendizagem adequados, seria necessário treinamento em tecnologia da informação, melhoria do acesso à internet e meios de evitar a sobrecarga.

The aim of this study was to evaluate the sensory characteristics of meat from cattle fed a cottonseed diet. A total of 100 beef cattle, with a mean initial live weight of 386.19 ± 4.48 kg and a mean slaughter weight of 527.82 ± 17.96 kg, aged between 13 and 48 months, were maintained in the feedlot for 88 days. This study was conducted with two treatments: a control treatment and feeding cattle whole cottonseed at a concentration of 15.9%. The animals were slaughtered for determination of sensory and volatile compounds in the beef. There was a difference in aroma, with better grades attributed to beef not fed cottonseed. The use of cottonseed promoted the occurrence of a strange taste in beef. There was a difference in the profile of volatile compounds between the groups. In general, feeding cattle cottonseed did not modify the qualitative sensorial aspects of beef; however, there was a greater chance of the development of some strange flavors of high intensity. The volatile compound profile of beef from cattle fed cottonseed was different than that of beef from control group.

Dermatitis or eczema is a form of the condition in which the layers of the skin (epidermis and dermis) have general inflammation which is usually influenced by endogenous and exogenous factors causing clinical abnormalities in the form of polymorphic efflorescence (erythema, edema, papules, vesicles, scales, lichenification) and itching complaint. This study simed to determine the treatment pattern given to patients with atopic dermatitis and contact dermatitis at the Jelakombo Health Center Jombang. This was an observational study with retrospective data collection. The data sourced used was existing medical records from January to December 2020. Data analysis was carried out descriptively with purposive sampling. The results showed that the most common dermatitis patients were atopic dermatitis (34%) which mostly treated with CTM+Dexamethasone. Patients with allergic contact dermatitis were 38 patients (38%), the most common drug regimen to manage it was Cetirizine+Hydrocortisone ointment. There were 28 patients (28%) with irritant contact dermatitis, which mostly treated with Cetirizine+Hydrocortisone Ointment followed by CTM + Dexamethasone. This study concluded that the drug regimen for the three types of dermatitis was almost the same, namely a combination of oral and topical antihistamines and corticosteroids. The antihistamines used were first-generation antihistamines (CTM) and second-generation (Cetirizine and Loratadine). Further assessment related to whether the sedation effect was wanted or it was disturbing side effect is needed. The widely used oral corticosteroid was dexamethasone, which is a high-potency corticosteroid, so its use must be judicious. Topical corticosteroids were hydrocortisone ointments that include low potency topical corticosteroids which are the first line of atopic dermatitis and allergic contact dermatitis.

Lemon (Citrus limon L.) is one of the fruits with the highest vitamin C content. Lemon (Citrus limon L.) is well-known as an ingredient for squeezing and extracting its juice for making beverages. In the process, the vitamin C contained in lemon juice (Citrus limon L.) is easily lost due to oxidation during processing and storage. Therefore, this study aims to determine the effect of storage temperature on vitamin C levels of lemon juice (Citrus limon L.) using UV-Vis spectrophotometry method. This research was conducted experimentally with variations in room temperature and cold storage temperature for 24 hours. The absorbance measurement of the sample was carried out at a wavelength of 265.5 nm. The results showed that variations in storage temperature had an effect on vitamin C levels in lemon juice (Citrus limon L.). The significant value of the F-test was 0.001 and the significant value of the T test at temperature and storage time were 0.02 and 0.000, respectively. The decrease in vitamin C levels followed a zero order kinetic model.  Vitamin C levels at cold temperature were lower than room temperature as indicated by the value of the reaction rate constant at cold temperature which was lower than room temperature.
