¿Fenêtre en longueur, hueco rasgado de suelo a techo o muro cortina? Una revisión crítica de la sintaxis del hueco en la modernidad
Authors: Marcos Carlos L. 
Published: December 2021

Le Corbusier planteó durante los años 20 del siglo pasado una gramática para el nuevo lenguaje de la arquitectura de hormigón armado y acero, la arquitectura moderna. Sus míticas viviendas realizadas durante esa década en colaboración con Pierre Jeanneret constituirían un elenco extraordinariamente influyente en los años posteriores y servirían de modelos para ilustrar una teoría que vería la luz en forma de texto en 1926 a modo de manifiesto fundacional, “Los 5 puntos de la arquitectura”. Su fenêtre en longueur –ventana rasgada horizontalmente– ponía de manifiesto la condición no portante de la fachada al tiempo que se apropiaba del horizonte y de una visión continua desde el interior. La arquitectura neoplasticista, sin embargo, directamente influenciada por la “destrucción orgánica de la caja” de Wright, planteaba rasgar huecos de suelo a techo. Ambas negaban la idea de perforar la fachada recortando los huecos sobre ella. Mies van der Rohe, el más riguroso en el detalle arquitectónico y la construcción de los arquitectos modernos, plantearía ya desde su proyecto para el rascacielos de la Friedrichstrasse de 1919 la incipiente idea del muro cortina que años después llegaría a materializar. En las siguientes líneas planteamos una discusión crítica acerca de la gramática de la modernidad y en particular respecto de la sintaxis del hueco.
Relationship of Exercise and Hospital Readmission After Spinal Cord Injury: A Secondary Analysis
Authors: Kubiak Stephanie , Sklar Elliot 
Published: December 2021

Importance: After spinal cord injury (SCI), as many as 45% of people experience at least one hospital readmission within 1 yr. Identification of feasible low-cost interventions to reduce hospital readmissions after SCI is needed.
Objective: To explore whether a relationship exists between routine exercise and hospital readmission rates 1 yr after SCI.
Design: We conducted a secondary analysis of data from the SCIRehab Project, a prospective cohort study.
Setting: Five SCI inpatient rehabilitation facilities across the United States.
Participants: Participants were people age 12 yr and older who had sustained an SCI, were admitted to a participating inpatient rehabilitation facility, completed the 12-mo postinjury interview, and reported exercising either monthly or not at all since discharge (N = 520).
Outcomes and Measures: The SCIRehab Project conducted 12-mo post–inpatient rehabilitation discharge interviews. As part of the interviews, self-reported hospital readmissions and exercise frequencies since discharge (self-reported number of months, average days per week, and average minutes per day of exercise participation) were collected and analyzed.
Results: A χ2 analysis determined that a significant correlation (φ = −.091, p = .038) exists between monthly exercise and hospital readmissions 1 yr postinjury. Compared with those who did not exercise, participants who exercised monthly had 8.4% fewer hospital readmissions.
Conclusions and Relevance: A relationship exists between exercise and hospital readmission, but follow-up research is needed to determine whether regular exercise reduces hospital readmissions among this population.
What This Article Adds: After discharge, 44% of the participants did not exercise during the first year after injury. Identifying or implementing accessible community exercise programs is an area of opportunity for occupational therapy practitioners and future researchers to explore.

Features of the optical medium of the surface of plant seeds
Authors: Zienko Stanislav , Belyakov Mikhail 
Published: December 2021

It was found that the integumentary tissue of plant seeds has the property of enhancing luminescence light. This phenomenon manifests itself in both the time and frequency domain.
The gain factor (in power), depending on the type of seed, varies from 1.7 (beans) to 2.6 (rye). To determine it, the optical medium of the plant seed surface was represented as a dynamic link having an input and output. The impulse (time) characteristic of the link was found by the relaxation curve of luminescence. The dependence of the gain on temperature is expressed in the fact that when it decreases from 50 oC to –30 oC, the gain increases from 1.73 to 2.48.
This phenomenon can be explained by the fact that at the stage of relaxation of luminescence, the absorption coefficient of the optical medium of the seed surface takes a negative value
Measuring complex for determining the characteristics
of high-voltage silicon carbide Schottky diodes in impulse modes
Authors: Zotin Vitaliy , Drakin Alexander , Rybalka Sergei , Demidov Andrey , Kulchenkov Evgeniy 
Published: December 2021

This paper describes a developed automated research measuring complex that allows one to determine the parameters of currents, voltages and power of silicon carbide Schottky diodes when applied reverse voltage impulses with amplitudes from 400 to 1000 V. The research
measuring complex was tested on DDSH411A91 («GRUPPA KREMNY EL») and C3D1P7060Q (Cree/Wolfspeed) silicon carbide Schottky diodes and allows to determine their
maximum values of the rate of rise of reverse voltage dV/dt (877 V/ns and 683 V/ns). Also, the maximum values of the current rise rate dI/dt were determined for DDSH411A91 (3.24 A/ns)
and C3D1P7060Q (3.72 A/ns) diodes. For the first time it was established that, when a reverse voltage impulse with an amplitude of 1000 V is applied, the maximum values of instantaneous fullpower reach 1419 VA for the DDSH411A91 diode and 1638 VA for the C3D1P7060Q diode.
Ultra-weak emission and microcurrents instabilities in blue GaN LEDs at different stages of degradation
Authors: Ekhanin Sergei , Tomashevich Alexander 
Published: December 2021

It is found that the ultra-weak luminescence observed in microcurrents mode in blue GaN LEDs with multiple quantum wells is due to tunnel-recombination processes with the participation of defect states and local potential wells of various depths, which arise as a result of
planar fluctuations of indium in the InGaN layers of the active region. Digital photographs were obtained and patterns of ultra-weak luminescence of the surface of LED crystals were analyzed. It is shown that the patterns of luminescence, along with the current-voltage characteristic, demonstrate significant changes after testing even at the initial stages of degradation, which indicates a high sensitivity of these parameters to degradation processes and the possibility of their use in diagnostic and non-destructive testing methods.

Authors: Kondratenko Vladimir , Kadomkin Victor , Tretiyakova Olga 
Published: December 2021

In this work, using two specific examples, a general approach to the mathematical modeling of thermal processes in the contact zones of fuel elements in the development and optimization of
various technological processes, systems and devices is considered. In the first example, a mathematical model of heat transfer in the contact zone (metal-hybrid thermal interface) between the heat-generating element and the heat-dissipating radiator is considered. In the second case, the thermal process in the processing of materials with a bonded diamond tool in the contact zone "diamond grain – binder – processed material" is considered and analyzed. The general approach to modeling thermal processes in the contact zones of various fuel elements makes it possible to optimize the parameters of technological processing modes and the correct operating conditions for products and systems

Storm after the calm!
Authors: Zacharias Carlos Renato 
Published: December 2021

To work with or to research on subjects related to Homeopathy and High Dilutions was never a monotonous activity! At all moment skeptics and believers are discussing about clinical and experimental proofs to validate the phenomenon behind the high dilutions. Independently how structured are their reasoning, and which part is attacking, the counterpart can always neutralize the discussion using the same antidote: the intrinsic uncertain provided by statistical methods, converging to an endless technical tie. For recent examples, we can cite the UK Parliament discussion, the attempt of collective suicide by skeptics and the Belgium KCE report. I agree they had consequences, but not enough to stop the polemics or this scenario. Behind and beyond all these discussion there is an important consensus: no one knows how a HD acts or even whether it really works or whether we are dealing with experimental artifacts! Each side has its beliefs and answers. However, we can extract an ironical consequence from that: the fight between the practitioners and politicians, believers and skeptics, is the motivation and the fuel for the researchers!! What a beautiful opportunity to challenge with a potentially new phenomenon!
The mind storming we are submitted should be taken as the basal state, a cyclical behavior own of this field. Cycles will repeat no matter the Science might be able to bring new theories, models, experiments, concepts, etc, about HD, to explain it or to refuse such hypothetical phenomenon!
Storms are cyclical and the winds can take us to new possibilities! And the calm period is very useful to repair or even redesign our structures and skills, preparing us to the next storm! But not to eliminate them!
I consider we are living a calm period, on which we should take a deep breath and relax to observe where the winds have brought us, what new possibilities we have, what challenges we must deal with!
This current IJHDRÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s issue and the next one will be an invitation to a break to meditation. IJHDR will publish the scientific contributions submitted to the GIRI (Groupe International de Recherche sur lÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢Infinitesimal) Symposia. The GIRI was created in 1986 aiming to bring together pharmacologists, biologists, physicians, chemists, physicists and other professionals to keep in touch, to exchange experiences and develop joint research projects about the biological effects of high dilutions, Homeopathy included.
In the current issue, IJHDR will publish 17 contributions presented on 2010 (Monaco) and in the next issues, more than 50 contributions submitted to the XXV GIRI Symposium (September 2011, Brazil). This way, IJHDR exerts its mission as a vehicle to share open access high quality information about research in HD.
Enjoy the calm, because new storms are coming!
