Dibujar fuerzas y cuerpos: una genealogía fragmentaria en la historiografía arquitectónica. École des Beaux-Arts, Marqués de Sade y Siegfried Ebeling= Drawing forces and bodies: A fragmentary genealogy in architectural historiography. École des Beaux-Arts, Marquis de Sade and Siegfried Ebeling
Authors: Cano Ciborro Víctor Manuel
Published: January 2024

AbstractThis article aims to shed light on a conception and representation often overlooked in architectural discipline historiography. It focuses not only on forms and objects but also on forces and bodies. For this purpose, a fragmentary genealogy of conflicts between schools, traditions, and architects is proposed. This genealogy will reveal how the technical rationality of the drawings at the École Polytechnique de Paris contrasted with the imagery of the École des Beaux-Arts in the eighteenth century. It will also explore how the dogmas of the Enlightenment were challenged by a Mason­ic architecture, seeking bodies and debauchery, as exemplified by the stories of the Marquis de Sade. Additionally, it will delve into how the abstract modernist diagram led by Le Corbusier was disrupted by the atmospheric energies, membranes, and sensitive bodies conceived by Siegfried Ebeling. ResumenEste artículo busca poner en valor una concepción y representación usualmente ignorada en la historiografía de la disciplina arquitectónica al focalizarse ya no sólo en las formas y en los objetos, sino en las fuerzas y los cuerpos. Para ello, se propone una genealogía fragmentaria de conflictos entre escuelas, tradiciones y arquitectos que revelará cómo en el sigo XVIII la racionalidad técnica de los dibujos de la École Polytechnique de París contrastaba con la imaginería de la École des Beaux-Arts; el modo en que los dogmas de la Ilustración eran desafiados por una arquitectura masónica en busca de cuerpos y libertinaje ejemplificadas por los relatos del Marqués de Sade; o la manera en que el diagrama abstracto modernista liderado por Le Corbusier era perturbado por las energías atmosféricas, membranas y cuerpos sintientes concebidos por Siegfried Ebeling.
La arquitectura religiosa de Glauco Gresleri: a propósito de su relación con la revista ARA = Glauco Gresleri’s religious architecture: On his relationship with ARA magazine
Authors: Fernández Cobián Esteban
Published: January 2024

AbstractDuring his years at the helm of the magazine Chiesa e Quartiere (CH.+Q.), the Italian architect Glauco Gresleri (1930-2016) kept in touch with some Spanish colleagues, although the relationship was never very extensive or intense. After the publication closed in 1968, he began to look for alter­native places from which to disseminate his religious production, and he found the perfect place in Spain: the young magazine ARA (Arte Religioso Actual), directed by the Dominican José Manuel de Aguilar. His association with the architect Silvano Varnier dates precisely from that period. Over time, Gresleri and Varnier would become the studio with the greatest presence in ARA during its twenty-seven years of existence. This text offers a critical analysis of the tandem’s religious work, with special emphasis on their international dissemination through their relationship with the Spanish magazine, a little-known aspect of their trajectory.    ResumenDurante sus años al frente de la revista Chiesa e Quartiere (CH.+Q.), el arquitecto italiano Glauco Gresleri (1930-2016) mantuvo contacto con algunos colegas españoles, aunque la relación nunca fue ni muy extensa ni muy intensa.

Published: January 2024

Modern industrialization increases the requirements for the accuracy of identifying allergens, especially those that have a negative impact – soy trypsin inhibitor (STI). Correct determination of the presence of STI in food products containing soybeans is key for product safety control and labeling. The authors set a goal to develop and certify a method for measuring the mass fraction of STI using an enzyme-linked immunosorbent assay – a technique that may increase the specificity of the method and avoid false-negative results.

   The object of research was a method for analyzing food allergens – an enzyme-linked immunosorbent assay carried out with a set of reagents produced by XEMA LLC. In the process of developing the measurement method, the main methodological factors influencing the accuracy of the measurement results were optimized: sample weight, time of its extraction, time and speed of sample centrifugation, ratio of supernatant liquid to ELISA buffer, incubation temperature, interaction time of the allergen-antibody complex with the coloring agent, the wavelength for measuring absorbance, and the maximum time for measuring absorbance after introduction of the stop reagent.

   The developed method was tested during an interlaboratory experiment with the participation of 5 laboratories. Metrological characteristics were established in accordance with RMG 61–2010. The proposed method was certified in accordance with the requirements of GOST R8.563-2009, No. 102–FZ. The method has a wide range of quantitative determination of the mass fraction of STI from 0.5 to 25.0 μg/kg (ppb) with a detection limit of 0.1 μg/kg (ppb) and a relative error of 40 %. Based on the results of the research, the Federal Information Fund for Ensuring the Uniformity of Measurements (FIF) registered a certified method for identifying and quantifying the content of non-infectious food allergens of plant protein origin in samples of all types of food products and objects related to the requirements for food products, swabs taken from working surfaces during production control using reagent kits for an enzyme-linked immunosorbent assay produced by XEMA LLC No. FR.1.31.2022.43884. The method is intended for use in testing laboratories involved in monitoring the quality and safety of manufactured products; it can be used to confirm product compliance with the mandatory requirements established in the Technical Regulations of the Customs Union TR CU022/2012.

Laser Phase Rangefinders: Ways to Improve Accuracy
Authors: Lubchenko D. A. , Mazurkevich A. V.
Published: January 2024

Scientific and technological progress in the field of geodetic and industrial measurements in terms of the use of laser rangefinders operating in ranges up to 5000 meters has led to a reduction in the error of such measuring instruments over the past ten years by two or more times. Such rapid development of high-precision rangefinder technologies has led to a significant revision of the requirements for their metrological support, as well as to the need to develop a new generation of length standards, the stock of metrological accuracy of which would provide an assessment of the metrological characteristics of all types of existing and promising length measuring instruments with a laser rangefinder. To solve this problem, the Institute’s staff conducted research within the framework of a number of thematic research and development works in terms of developing the appearance of a new generation of length standards operating in the range up to 5000 meters in an open atmosphere. Within the framework of this article, one of the developed models of a high-precision complex of measuring instruments for length and coordinate increments is considered, which is a serial high-precision laser phase light meter, modified by the institute’s staff in terms of the system for receiving and processing measuring signals. At the same time, in order to increase the accuracy of length measurements using the developed range finder layout, it is proposed to investigate ways to reduce the errors of the model components of the boundaries of its error. To ensure the smallest error in determining the hardware correction of the rangefinder layout, it is proposed to use funds from the state primary special standard of the unit of length. As promising ways to reduce the error in determining the phase difference of signals, it is proposed to use digital recording and signal processing devices that implement a method for calculating the phase difference of signals by mathematically processing the recorded data using a specially developed computational algorithm based on Fourier analysis. For the most accurate determination of the values of the pulse repetition frequency of signals and the values of the speed of light on the measured track, it is proposed to improve the means of determining these indicators. The use of the proposed methods to improve the accuracy of measuring the length of laser phase rangefinders allows you to provide the necessary margin of metrological accuracy.

GET 63–2019: Innovative Method for Stabilizing Liquid Flow Rate in a Reference Installation 3
Authors: Tukhvatullin A. R.
Published: January 2024

Establishing the pinpoint accuracy of national primary standards for units of mass and volume flow rates (mass and volume) of liquid (water) is a priority in the national economy of most states. In Russia and abroad, the principle of operation of standards for units of flow rate and amount of liquid is based on the gravimetric weighing method, i. e., on measuring the mass of liquid entering a weighing container over a certain averaging time interval. The decisive condition for the accuracy of the result of the standard is the stabilization of liquid flow rate, as well as the choice of the optimal method for creating a forced flow of liquid in the pressure pipeline and measuring line. The widely accepted method of creating a forced flow of liquid by placing it at a height or supplying it using pumps has one inconvenient consequence – the bulkiness of the standard design. The creation of such a design entails economic, labor, and time costs, which can adversely affect the test conditions and results. The author’s innovative method of active damping of pressure and fluid flow fluctuations, which eliminates the need to place the pressure tank at a great height above ground level, allows minimizing inconveniences. This method is implemented in the pressure pipeline and measuring line of the reference installation 3 of the State Primary Special Standard of Units of Mass and Volume of Liquid in a Flow and of Mass and Volume Flow Rates of a Liquid GET 63–2019.

   The purpose of the article is to substantiate and experimentally confirm the high efficiency of this method.

   The results of experimental research of changes in the absolute pressure in the air cushion and the liquid level in the pressure tank of the stabilization module confirmed the efficiency of the proposed method based on the obtained minimum values of the relative deviations of the instantaneous and average liquid flow rates. The engineering solution presented in the article is of interest to economic entities and commercial organizations interested in reducing the costs of testing the volumetric flow rate (mass and volume) of liquid (water).

Context: To evaluate intubation difficulty comparing Macintosh, Miller and Truview blades in patients with immobilized cervical spine. Aims: 1. To compare the difficulty during orotracheal intubation between Macintosh, Miller or Truview laryngoscopes utilizing the Intubation Difficulty Scale (IDS). 2. To compare the time taken for intubation. 3. Success rate of intubation in the three groups. Settings and Designs: Prospective randomized cross sectional study. Methods and Materials: This study was conducted in healthy Patients to evaluate the difficulty during intubation using the mentioned laryngoscopes, with the neck immobilized using Manual In-line Axial Stabilization (MIAS). Evaluation was done using intubation difficulty score (having seven parameters), success rate and duration of intubation. Intubation failure was defined as duration exceeding 120 seconds for which MIAS was relaxed and intubation was done conventionally. Statistics: One Way Analysis of Variance with Duncan’s mean test. Results: All patients in the Macintosh group , 18 (90%) in Miller group and 16 (80%) in Truview group were intubated successfully. The duration of intubation was significantly longer and IDS score, least in Truviewgroup. Truview provided better glottic view and required less optimizing maneuvers. Conclusions: The Intubation Difficulty Scale (IDS) score in parients with cervical spine immobilization (MIAS) is significantly least with TruView laryngoscope compared to conventional laryngoscopy using Macintosh or Miller laryngoscope. The time taken for intubation was shortest with Macintosh laryngoscope. Success rate of intubation is highest with Macintosh laryngoscope while it is least with TruView laryngoscope under the stipulated time limit (120 seconds) for laryngoscopy.

Introduction: Supra Glottic Airway devices have set a new trend in airway maintenance since their invention. Availability of these devices in the paediatric sizes has revolutionized their use. Endo Tracheal Tubes have always been considered “Gold Standard” owing to their ability of maintaining stable respiratory parameters and in prevention of aspiration. We have compared the repiratory parameters achieved with Paediatric I-Gel, Proseal -LMA and Endo Tracheal Tube. Description: 120 children aged 2 to 12 years, both sex, ASA 1 and 2, posted for elective surgery were included in the study. They were divided into 3 groups of 40 each - Endo Tracheal Tube (E), Proseal LMA (P-LMA) and I-GEL respectively. The device was inserted after induction of anaesthesia and the respiratory parameters namely SpO2 and EtCO2 were recorded at various time intervals. Result: All values were analysed and expressed as mean +/– SD. Statistical comparison was done by unpaired student “t”- test and chi square test. The values obtained for various time intervals were found to be statistically insignificant for all the three devices. Conclusion: PaediatricProseal LMA (P-LMA) and I-GEL are very much comparable with Endo Tracheal Tube (E) with regard to respiratory parameters and hence can be safely used as an alternative airway in the paediatric population.

Introduction: A recent development in the treatment of post-operative pain is the use of peripheral nerve blocks. The technique involves blocking the conduction of nerve impulses by deposition of local anaesthetic around the nerve or nerves supplying the area of interest. Consequently, the sensory and/ or motor supply to the area supplied by the nerves, are effectively abolished, thus helping to achieve anaesthesia and analgesia. Methodology: The patients were selected by convenience sampling and those who matched the selection criterion, were briefed about the nature of the study and the procedures involved, in a language understood by them and written informed consent was taken. Descriptive data of the patient such as name, age, sex and detailed medical history, was collected. They were randomized into two groups with the help of computerized randomization software. Results: In our study it was noted that the mean total rescue analgesic consumption in patients belonging to Group S (over a period of 24 hours) was 73.3 mg. Whereas the mean total rescue analgesic consumption in Group T was only 35 mg. This difference in the mean total rescue analgesic consumption between the two groups was found to be statistically significant (p value < 0.001). Conclusion: Patients in both Group T and Group S experienced some degree of nausea at the 2, 4 and 6 hour intervals, but the PONV scores of both the groups were comparable. Thereafter, patients in both the groups were asymptomatic.

Background: Juvenile nasopharyngeal angiofibroma(JNA) is a locally invasive benign vascular tumor, controlled hypotension is used to facilitate endoscopic resection. Nitroglycerine and Dexmedetomidine were compared as hypotensive agents in this study. Methods : Ethics Committee has approved the study which was conducted at Government ENT hospital, Hyderabad during 2016 – 2018.Study included 40 patients divided into two groups, Group D (Dexmedetomidine) n=20,1µg/kg over 15 min followed by a maintenance infusion at 0.5µg/kg/hr,GroupN(Nitroglycerine) n=20- Nitroglycerine @ 0.5µg/kg/min and titrated in doses 0.5-5µg/kg/min for target blood pressure respectively. Results : A statistically significant difference was observed in the study in mean pulse rate between two groups Group D-66.09±2.83, Group N-86.59±4.24, p value 0.0001. Blood loss was lower in Group D-310.71±140.58 compared to Group N 482.61±141.42 , and is statistically significant (p value 0.0004). SBP, DBPand MAP were comparatively lower in Group D throughout the surgery. Conclusions: Dexmedetomidine is a better hypotensive agent with favourablehemodynamics and significantly less blood loss when compared to Nitroglycerine.
