Published: December 2022

L’étude a eu pour objectif de tester et comparer l’efficacité de deux protocoles classiques d’induction des chaleurs, CoSynch avec ou sans progestérone, chez les zébus Goudali. Elle a porté sur 39 animaux. Trois semaines après l’insémination artificielle (IA), les femelles ont été observées pour identifier les cas de retour des chaleurs. Elles ont été soumises à un examen échographique utérin à partir du 44e jour après l’IA. Le taux d’induction (pourcentage de vaches vues avec des chaleurs par rapport au nombre de vaches traitées) ainsi que de rétention du dispositif intravaginal à base de progestérone ont été tous les deux de 100 %. Les taux de fertilité en première insémination ont été de 10,5 % et 35 % suite respectivement aux protocoles CoSynch standard et CoSynch + progestérone (p = 0,075). Les vaches cyclées ont présenté un taux de fertilité satisfaisant (80 %) avec le protocole Cosynch + progestérone contrairement à celles non cyclées (20 %) et à celles ayant subi le traitement CoSynch standard. Chez les zébus Goudali, l’ajout de progestérone augmente donc les performances de reproduction d’un protocole CoSynch.

A Cloud-based Mobile Privacy Protection System with Efficient Cache Mechanism
Authors: Dai Wenyun , Chen Longbin
Published: December 2022

People increasingly rely on their mobile devices and use them to store a lot of data. Some of the data are personal and private, whose leakage leads to users' privacy harm. Meanwhile, mobile apps and services over-collect users' data due to the coarse-grained access control approach utilized by the mobile operating system. We propose a cloud-based approach to provide fine-grained access control toward data requests. We add privacy level, as a new metadata, to data and manage the storage using different policies correspondingly. However, the proposed approach leads to performance decreases because of the extra communication cost. We also introduce a novel cache mechanism to eliminate the extra cost by storing non-private and popular data on the mobile device. As part of our cache mechanism, we design a user-preference-based ordering method along with the principle of locality to determine how popular some data are. We also design a configurable refresh policy to improve the overall performance. Finally, we evaluate our approach using a real phone in a simulated environment. The results show that our approach can keep the response time of all data requests within a reasonable range and the cache mechanism can further improve the performance.
BPDST: Blockchain-Based Privacy-Preserving Data Sharing on Thin Client for Electronic Medical Records
Authors: Xu Lu , Lin Mengchen , Feng Yong , Sun Yani
Published: December 2022

Sharing medical data can improve the quality of medical services and reduce costs. However, the current Electronic Medical Records (EMRs) are scattered and easily tampered with, which is not conducive to the sharing of EMRs and is not compatible with thin clients. Fortunately, blockchain technology is tamper-proof, decentralized, auditable, and meets the above requirements. To solve these problems, we first propose Blockchain-Based Privacy-Preserving Data Sharing on Thin-Client for Electronic Medical Records (BPDST) approach that combines the k-anonymity and cloud storage, which thin clients can run like a full-node user and safeguard user's EMRs privacy concurrently. Using this approach, patients can control their own EMRs, while the consortium blockchain is responsible for the transaction process and sending the correct results to the patients. BPDST can also share information without leaking or tampering with EMRs' privacy, achieving the purpose of sharing medical data and privacy protection. In the medical field, this study can effectively protect users' privacy when sharing medical data to provide convenience for users and break the "island" phenomenon among various medical institutions. Security analysis and extensive experiments show that BPDST is secure and practical for sharing EMRs.
Some Aspects of European Defence Industry Development
Authors: Koroschupov V.
Published: December 2022

As a result of the analysis of defence spending in European countries for the period 1990–2022, the author reveals a trend towards underfunding of their defence-industrial base. Due to the fall in defence spending, there is a reduction in European defence companies in Europe, some companies go into the commercial sector, the other part is trying to consolidate. The armed forces of European countries conduct exercises and fight on a multinational basis, and purchase weapons on a national basis. This situation does not allow industrial enterprises to consolidate demand, which makes it possible to increase production volumes. By researching the state of the defense-industrial base of European countries, it becomes evident that there are disagreements between the states of Europe about which is better to buy samples of weapons. Some are in favor of purchases in the United States, others – for joint European projects, and others – for national ones. For example, for fighters, we are talking about choosing between the F‑35, Eurofighter Typhoon, Dassault Rafale or SAAB. A study of data on arms exports from the United States to Europe shows that Europe has lost its status as the main export destination of the United States. The results of research illustrate that the procurement of weapons is a long and complex process, the programming of the construction of the armed forces and the costs are planned, taking into account the threats of tomorrow, in advance. The research findings indicate that the prevailing conditions of peace and stability of the last 30 years have shaped the image of the defense industrial base of European countries unable to produce military products in large quantities and in a short time. The author comes to the conclusion that the ambitions of Europe exceed the available resources.
Diario 1969: acerca del relato personal de Bernard Rudofsky sobre el descubrimiento de Frigiliana
Authors: García-Diego Villarías Héctor , Villanueva Fernández María
Published: December 2022

ResumenBernard Rudofsky dedicó buena parte de su vida a explorar una manera de habitar personal y plena, lo que tuvo su reflejo en las numerosas exposiciones y publicaciones que alumbró. Y parte de ese proceso de investigación fue vertido en los diversos intentos de construir una casa para sí mismo y su mujer Berta, y que concluyeron con la construcción de ‘La Casa' en Frigiliana a principios de los años setenta. La presente investigación revela por vez primera las vicisitudes que rodearon el hallazgo del lugar y su posterior adquisición por parte del matrimonio a través del testimonio de Rudofsky anotado en uno de sus diarios personales. El artículo reconstruye con detalle la peripecia del matrimonio en España en 1969 al cotejar y extraer la información manuscrita en las 144 páginas de las que se compone este documento, información que no ha sido tratada con anterioridad. El episodio encierra un interés triple: en primer lugar, el del registro histórico de este suceso singular y el importante papel jugado por esta construcción en clave biográfica; en segundo lugar, el del encuentro del arquitecto extranjero con la España de la época —y que por tanto permite evocar a lo que pudieron enfrentarse algunos otros casos semejantes; por último, cabe destacar la singularidad de un proceso de proyecto que incluye el lugar en un estadio intermedio y que precisamente pone de relieve la intensa relación existente en este caso entre la casa, el entorno, el habitante y diseñador, y el habitar.AbstractBernard Rudofsky dedicated a significant part of his life to exploring a personal and fulfilling way of living, which was reflected in the numerous exhibitions and publications that he produced. Part of this research process was funneled into the various attempts to build a house for himself and his wife Berta, which concluded in the early seventies with the construction of La Casa in Frigiliana. This investigation reveals for the first time, from Rudofsky’s own account in one of his diaries, the challenges and mishaps that surrounded the discovery of the place and its subsequent acquisition by the couple. The article is an attempt to comprehensively reconstruct the couple’s ups and downs in Spain in 1969 by extracting and collating handwritten information from 144 pages of his diaries; information that has not been previously looked into. This article has a three-fold focus: firstly, that of the historical record of this unique event and the important role played by this construction in a biographical key; secondly, that of the meeting of the foreign architect with the Spain of the time, which allows us to imagine what other similar cases may have faced; finally, it is worth highlighting the uniqueness of a project process that includes the place in an intermediate stage and that highlights the intense relationship that exists in this particular case between the house, the environment, the user and designer, and living there.
Infrastructure space: lógicas operativas en la práctica arquitectónica del siglo XXI
Authors: Carruthers Luz
Published: December 2022

ResumenEsta investigación propone estudiar la intersección entre la arquitectura del s. XXI y la infraestructura, entendida como hecho físico y concepto abstracto, a través de la noción de espacio infraestructura. Desde la década del 60’, la definición de infraestructura se ha desplazado hacia una versión más conceptual, moviéndose entre distintas disciplinas, desde las ingenierías a las humanidades. En la actualidad, a su condición material como sistema urbano se le superpone su potencialidad como herramienta transdisciplinar capaz de explicar fenómenos económicos, sociológicos y políticos. Su doble condición material-conceptual y su capacidad de operar a múltiples escalas obligan a ampliar una vez más el significado de infraestructura, abriendo paso al concepto de espacio infraestructura. La hipótesis de este artículo es que el espacio infraestructura es un dispositivo práctico y teórico extraído de las lógicas infraestructurales, que se consolida como herramienta de proyecto en la arquitectura contemporánea. Esta arquitectura ya no busca reproducir el modelo infraestructural, sino sus lógicas, lo cual le da libertad para aplicarlas en el proyecto, con independencia de la escala y el programa del que se ocupe. Para demostrarlo se postularán los conceptos de infraestructura y espacio infraestructura, los cuáles serán contrastados con una serie de obras de arquitectura con el fin de exponer las estrategias proyectuales específicas que surgen de esta relación, dando como resultado el espacio infraestructura. AbstractThe purpose of this research is to study the intersection between 21st century architecture and infrastructure, understood as a physical fact as well as an abstract concept, through the notion of Infrastructure Space. Since the 1960s, the definition of infrastructure has been changed towards a conceptual version, moving among different disciplines, from Engineering to Humanities. At present, its material condition as an urban system is overwritten with its potentiality, as a transdisciplinary tool, which can explain economic, political, sociological and urban phenomena. Its double material-conceptual condition and its capacity to operate in multiple scales oblige us to expand once again the meaning of infrastructure, opening up to the concept of infrastructure space. This paper hypothesis relies on the fact that infrastructure space is a practical and theoretical device, extracted from infrastructural logics, which is consolidated as a design instrument in contemporary architecture. This new architecture seeks no longer to reproduce the infrastructural model but its logic. This allows us to apply them in the project with independence with respect to the scale and the program involved. To prove this, two concepts of infrastructure and infrastructure space will be postulated, which will be compared to several architectural works in order to show specific project strategies derived from this relation, resulting in infrastructure space.
The ‘yacht’ elevated to ‘ocean liner’1. History of the Real Club Náutico de San Sebastián beyond the Lecorbuserian myth, 1905–1929
Authors: Ruano Hernansanz Miguel Ángel
Published: December 2022

AbstractThe 1929 extension of the Real Club Náutico de San Sebastián (San Sebastian Royal Yacht Club), the work of Joquín Labayen and José Manuel Aizpurúa, was quickly labelled as a work influenced by Le Corbusier’s style paquebot, despite the fact that its authors never acknowledged this influence. Research into the history of the building, including the three main reforms it underwent in 1905, 1916 and 1929, revealed that all the reforms had sought the same naval appearance that the Donostia architects pursued in 1929, and that this decision had, on each occasion, come from the club’s board of directors. Indeed, Aizpurúa confessed to Giedion in a letter that the project was chosen because it resembled a ship. The previous projects were misunderstood because they were compared, out of context, with ocean liners; they were neither of the right size nor from the right period to be identified with this type of ship, whereas the 1929 refurbishment was. The ship model of the 1905 and 1916 buildings was the ‘schooner’, a smaller, lighter, sailing ship used for maritime competitions. Elements of these buildings which had so far been considered ‘decorative’, such as the mast, portholes, or hatches, were in fact defining features of this naval typology. First José Ángel Sanz Esquide broadened the spectrum of Aizpurúa’s influence, and later José Ángel Medina Murua practically delimited the inspiration of the Real Club Náutico building project to the ideas of Le Corbusier. But we might ask whether this intense, but anecdotal, Lecorbusierian influence really took place, or whether it was just the brainchild of the club’s historical tradition, of significant quality but without greater theoretical pretensions.
24 Galleries, a museum: The Survey as a Design Tool
Authors: Salcedo Sánchez Esteban
Published: December 2022

Abstract In the mid-1970s in Madrid, it’s possible to identify a series of experiences that went beyond traditional architectural practice, the established domains of academia and the usual dynamics of editorial and institutional activities. The art galleries, with their publications, curators, collectors, critics and visitors, proved to be a prolific setting for an informal network of agents and institutions that, through programming events of various formats, instituted an active mediation in the critical formation of the citizenry. The seminar “Nuevos Comportamientos Artísticos” (“New Artistic Behaviors”), held at the Madrid’s German Institute in 1974, was one of these events. Its gallery proved to be a pioneer in the exhibition of practices linked to art and design, which openly promoted their expansion into other fields of knowledge based on a local interpretation of what was noticed in Spain as “conceptual art”. The action “Survey of 24 art galleries in Madrid,” was the contribution to the seminar of the multidisciplinary collective Grup de Treball (GdT), and serves here to illustrate the activation of this network of galleries as a ‘counter-project’. An act of design, based on Peter Eisenman’s definition of ‘Conceptual Architecture’, that transcends art and controversies to offer an alternative. The exhibition of the survey’s answers accumulated the values of language, interface, platform and medium necessary to redefine the framework of relations between its participants. Whose association gathered a community with the capacity to be a Museum: a dematerialized, fragmented and heterogeneous institution that challenged conventional relationship between art, citizenry and the market.

Selection of Adequate EPS-Block Geofoam for Use in Embankments Subjected to Seismic Loads
Authors: Khosravi Marzieh , Arellano David
Published: December 2022

Expanded polystyrene (EPS)- block geofoam is an extremely lightweight fill material utilized in many geotechnical applications such as roadway and railway embankments. This study provides a methodology for analyzing the load-bearing capacity and horizontal sliding failure mechanisms for seismic internal stability analysis of EPSblock geofoam embankments. The seismic analysis procedure is demonstrated by analysis of one of the EPS-block geofoam embankments that Tennessee Department of Transportation is proposing a partial replacement of an existing bridge in Memphis, Tennessee in the USA. The objective of the seismic analysis procedure is to determine stresses from anticipated earthquakes to select the proper type of EPS considering both the 1% and 2% strain criteria that can support the anticipated increase in stress and potential horizontal displacements due to dynamic and static stresses. The study revealed that the 2% criterion provides an economical advantage compared to the 1% criterion.
A Two-step FE Model Updating Approach for System and Damage Identification of Full-Scale Prestressed Bridge Girders
Authors: Malekghaini Niloofar , Ghahari S. Farid , Ebrahimian Hamed , Bowers Matthew , Ahlberg Eric , Taciroglu Ertugrul
Published: December 2022

The average age of in-service bridges has increased in recent years in the United States. To address this issue, structural health monitoring and damage identification approaches can be employed to prioritize maintenance/replacement of aging bridges. Among the damage identification and operational health monitoring approaches, finite element (FE) model updating methods can offer a solution to evaluate the mechanics-based characteristics of bridges. However, in a real-world setting, unidentifiability and mutual dependency between model parameters, modeling errors, especially due to boundary conditions, as well as ill-conditioning of updating algorithms can pose challenges to the application of FE model updating methods. To address these challenges, this study presents a two-step FE model updating approach. In the first step, modal-based model updating is used to estimate linear model parameters mainly related to the stiffness of boundary conditions and material properties. In the second step, in order to refine parameter estimation accounting for nonlinear response behavior of the bridge, a time-domain model updating is carried out. In this step, boundary conditions are fixed at their final estimates using modal-based model updating. To prevent the convergence of updating algorithm to local solutions, the initial estimates for nonlinear material properties are selected based on their corresponding final estimates in the modal-based model updating. To validate the applicability of the two-step FE model updating approach, a series of forced-vibration experiments are designed and carried out on a pair of decommissioned and deteriorated prestressed bridge I-girders. After carrying out the two-step FE model updating, the final estimates of concrete compressive strength are shown to provide reasonable assessment of the damage extent in the girders.
Galaxy Number Counts from the Sloan Digital Sky Survey
Authors: Marr John Herbert
Published: December 2022

Data from DR17 of the SDSS in the g, i, r, u, z bands were used to compute galaxy number counts and galaxy density per square degree in the composite bJ band over two areas of sky centred on the North Galactic Cap (NGC) and above the South Galactic Cap (SGC), with areas of 5,954 and 859 sq. deg. respectively and a combined count of 622,121 galaxies within the limits of redshift ≤0.4 and bJ≤20. The comparative densities confirmed an extensive void in the Southern sky with a deficit of 26% out to a redshift z∼0.15. Number counts in the K−, R−, I−, H−, B− and U−bands were derived from the Durham Extragalactic Astronomy and Cosmology catalogue and were well fitted to a general relativity (GR) cosmological model over their whole range, requiring only modest luminosity evolution, except for a steeper curve in the B−band at faint magnitudes required a star-burst evolutionary model to account for the excess faint number counts. Extending the SDSS redshift-number count survey to fainter and more distant galaxies with redshift ≤1.20 and bJ≤24 showed a secondary peak in the number counts that may account for this observed apparent excess of faint blue galaxy counts. Individual examination of a sample of these galaxies suggested that many were QSOs, bright X-ray or radio sources, or evolving irregular galaxies with rapid star formation rates. This sub-population at redshifts 0.45−0.65 may account for the excess counts observed in the B− optical band.

Hosting FIFA World Cup obviously produce immense socio-economic impacts to a nation. Proximal non-host city perception to mega event was frequently explored, while distal non-host city perception has less investigated. This study assessed the socio-economic impacts of FIFA World Cup Qatar 2022 in Chon Buri Sports City residents. Participants were 422 Chon Buri Sports City residents from eleven districts. Perception on socio-economic impacts of hosting FWC Qatar 2022 was measured from the translated Scale of Perceived Social Impacts. Extracted seven dimensions by confirmatory factor analysis is consistent with empirical data. Positive impact dimensions are Community Development, Community Pride, Economic Benefits. Negative impact dimensions are Traffic Problems, Security Risks, Economic Costs, and Environmental Concerns. Chon Buri Sports City residents perceived fewer negative impacts than other non-host city residents. Positive impacts of hosting FWC Qatar 2022 has more influenced on Chon Buri Sports City residents’ perception than negative impacts. These findings advantage for sport stakeholders to deeper understand the impacts of mega event hosting.

Authors: Ayusso Luis L. , Girol Ana Paula , Burdmann Emmanuel A.
Published: December 2022

Kidney diseases are a global health problem, and their frequency is continuously increasing. Available treatments provide limited kidney protection. The protective effect of the green tea polyphenol epigallocatechin-3-gallate (EGCG) in several diseases have been extensively investigated. Experimental and clinical studies have shown that the antioxidant, anti-inflammatory, and anti-apoptotic properties of EGCG are promising for the treatment and/or prevention of kidney diseases. This review analyzes the available evidence on the effects, and the likely protective mechanisms of action, of EGCG in a broad spectrum of kidney diseases, including acute kidney injury, drug-induced nephrotoxicity, kidney stone disease, diabetic nephropathy, chronic kidney disease, and kidney fibrosis.

Published: December 2022

In the Yucatán Peninsula, anthropogenic activities such as urbanization and final dispose of solid and wastewaters critically impact aquatic systems. Here, we evaluated the anthropogenic-related environmental alteration of Lake La Sabana, located in the northern limit of one of the main cities of the Mexican Caribbean. We evaluate lake water quality using physical, chemical, and microbiological indicators, and heavy metals in surficial sediments and fish tissue to evaluate the potential environmental risk. Multivariate analyses reveal that environmental conditions in La Sabana are spatial and temporal heterogeneous. Medium to bad water quality was determined within basins by the NSFWQI, related with the degree of anthropogenic influence. The center-south zones display critical microbiological values largely exceeding national standards. Heavy metals in sediments (Zn>Hg) and fish tissue (Hg) were relatively low, but Hg concentration threat the ecological environment. Incipient wastewater treatment and final dispose in La Sabana is the main responsible of changes in the trophic status and nutrients availability, which in turn may have promoted changes in the biological structure and aquatic plant invasions. Lake La Sabana can be considered a model of the potential sequential effects of the anthropogenic alterations in oligotrophic karts tropical aquatic systems in Yucatán Peninsula.
Insulin-Based Treatment for Amyotrophic Lateral Sclerosis
Authors: Rappoport Ari
Published: December 2022

Background Amyotrophic Lateral Sclerosis (ALS) is a devastating disease involving motor neuron degeneration. The few drugs approved for treatment have at most a marginal benefit, and death usually occurs 2-5 years after diagnosis. Methods A thorough manual examination of the relevant literature, covering over 35,000 papers. Results Two major phenomena that are generally not known to clinicians were found. First, insulin signaling is impaired in ALS even in patients not diagnosed with diabetes (DB). Almost all studies that have explicitly tested insulin function in non-DB ALS patients using glucose tolerance tests (18 out of 20, 1964-2022, different groups) have found it to be impaired. Second, there is strong evidence for excessive insulin-independent glucose uptake (IIGU) in ALS. In addition, (i) early/late diabetes are associated with increased/decreased risk, respectively; (ii) insulin-based diabetes drugs are protective in ALS in large retrospective human studies; and (iii) strong animal and human evidence shows that insulin opposes all of the major pathological processes in ALS. Conclusion Most ALS patients have insulin impairment, yet this is commonly not diagnosed, likely because excessive IIGU normalizes glucose levels. The impairment promotes disease progression. Late diabetes is associated with decreased risk because high glucose levels indicate non-excessive IIGU, and because diabetes drugs are protective. Insulin-based treatment (e.g., GLP1 agonists, insulin) is beneficial and can be disease-modifying in ALS and in frontotemporal dementia variants comorbid with ALS. ALS patients should be routinely tested for insulin function and treated if test results are positive.
In the United States, Obesity Is So Prevalent Could It Be Described as a Pandemic?
Authors: Tzenios Nikolaos , Tazanios Mary , Chahine Mohamad
Published: December 2022

In the United States, obesity is prevalent, and it could be described as a pandemic. Obesity is excessive fat accumulation, leading to a BMI ≥ 30 (Fruh, 2017). Surveys conducted by the CDC show that the obesity prevalence in the US is on the rise, as several obese people rose from 30.5% to 41.9% between 1999 and 2020 (Bryan et al., 2021). During the same time, several people suffering from severe obesity rose from 4.7% to 9.2% (Bryan et al., 2021). Additionally, childhood obesity is on the rise. Statistics indicate that between 2017-2020 over 19.7% of children and adolescents aged 2-19 years had obesity. During the same period, obesity prevalence in children aged 2-5 years, 6-11 years, and 12-19 years olds was 12.7%, 20.7%, and 22.2%, respectively (Bryan et al., 2021). With so many people suffering from obesity, the WHO declared it a public health crisis (WHO, 2020). The COVID-19 pandemic further exacerbated the prevalence of obesity in the US. According to the surveys, there was a 4.4% increase in obesity between 2019 to March 2020 due to lifestyle changes that were put on people during the COVID-19 pandemic (Akter et al., 2022). Many comorbidities are associated with obesity. Without adequate health interventions, millions of people could suffer severe health disorders like respiratory problems, type II diabetes, psychological issues, gastrointestinal disorders, and cardiovascular diseases. It is also essential to develop health interventions to mitigate obesity due to its strain on the healthcare system. Research shows that people suffering from obesity spend $2,505 more than people with average weight on healthcare (Cawley et al., 2021). Obesity has financial ramifications in every healthcare category: inpatient, outpatient, and prescription drugs (Cawley et al., 2021). One essential action toward the efforts to mitigate the soaring obesity rates is understanding the demographic inequities across populations and how they can be resolved.

Synthesis of Core-Shell Fe3O4/C18/SiO2/[3 (2-Aminoetil amino) propyl] Trimethoxy silane has been conducted to study its adsorption kinetics of Cu2+ and Cr6+ ions. Fe3O4 synthesis was carried out to form cores that have magnetic properties. The aim of the coating C18/SiO2/[3(2-Aminoetilamino) propyl] trimethoxy silane was to protect these cores from physical degradation due to acids and bases, as well as the application of synthetic materials. The sono-coprecipitation method showed good results under N2 gas flow with the results of black crystals. The success of SiO2 and [3(2-Aminoethylamino) propyl coatings the transformation of the color showed Trimethoxy silane into brown and weight gain of the synthesis result. Analysis of XRD data showed that little Fe2O3 impurities were clarified by FTIR data showing the presence of amine groups from the starting material. The SEM-EDX and TEM showed a spherical shape with a core-shell system. The adsorption kinetics model was studied using two kinetics models for Cu2+ and Cr6+ ions. The results were demonstrated by the suitability of Cu adsorption to the pseudo order 1, with an adsorption rate of 0.0333 min-1, whereas for Cr corresponded to pseudo order 2 with an adsorption rate of 0.00536 gmM-1min-1.

This study aims to determine the media's quality based on the chemistry teacher's assessment, determine the readability of the media based on the assessment of students who have received this material, and determine the impact of this media trial in chemistry learning. The development design used is ADDIE (Analysis, Design, Development, Implementation, and Evaluation). At the implementation stage, the posttest control group design was used by involving two classes as the control and experimental class. The variable measure is students achievement. The results obtained are that the Chemdroid learning media has been developed and declared valid by four experts. The assessment results by five high school chemistry teachers were Very Good, with a mean value of  3.31. The results of this assessment state that the Chemdroid learning media is suitable for use as a learning media for thermochemistry. In comparison, the readability test results by 16 students from 4 various senior high schools resulted in Good criteria with a mean of 3.24, which means that this media is legible and useful for students in various groups. The analysis of the implementation results states that the two classes have a significant difference.

This research had been carried out on the analysis of nitrite and nitrate in bread by UV-Vis spectrophotometry through a diazotization reaction. The research began by determining the optimum conditions for nitrite analysis while nitrate needs to be reduced using Zn powder or spongy cadmium so it can be analyzed by UV-Vis spectrophotometry. Ionic interference could affect nitrite analysis using UV-Vis spectrophotometry, then both nitrite and nitrate analysis methods were validated based on the method validation parameters. The diazotization reaction produced an azo compound which have λmax 546 nm. The validation results showed that the linearity of nitrite and nitrate has R2 = 0.9990 in the range 0-1 mg L-1 with a molar absorptivity value for nitrite without a reduction process was 3.37 × 104 L mol-1 cm-1, meanwhile 2.91 × 104 L mol-1 cm-1 and 3.83 × 104 L mol-1 cm-1 was shown for the reduced nitrite of Zn powder and spongy cadmium. The detection limits were 4.29 × 10-3, 9.34 × 10-3 ,and 7.58 × 10-3 mg L-1 .The %RSD results were 0.31-1.83% with recovery percentage of nitrite and nitrate in the range of 83.2-104.4%. The strongest ionic interference was shown by Fe2+ and Fe3+ ions at concentrations < 10 mg L-1. WHO has confirmed that the daily intake for nitrate that is acceptable to be consumed by human is 0-3.7 mg/kg.
