Published: March 2022

O b j e c t i v e s. The problem of constructing a new class of physically uncloneable functions (PUF) based on controlling the signal propagation delay through the elements lying on the path of its propagation is being solved. The relevance of this problem is associated with the active development of physical cryptography. For its implementation, the following goals are pursued: the construction of the basic elements of the PUF and their modifications, the development of a methodology for constructing controlled ring oscillators based on XOR elements and controlled ring oscillators based on multi-input signal switching.M e t h o d s. Methods of synthesis and analysis of digital devices were used, including those based on programmable logic integrated circuits (FPGA), the basics of Boolean algebra and circuitry.R e s u l t s. It is shown that combined PUFs based on RS-flip-flops implement the idea of controlling the signal delay by choosing a path, which is a series-connected elements selected in accordance with the PUF request. A technique for constructing an PUF with a controlled delay through each element of the path has been developed as a development of the idea of controlling the signal delay along the path. The features and properties of PUF with controlled delay of signals of the ring oscillator type are investigated and possible solutions are shown for the case of two-bit input requests. A basic element and its modifications are proposed for constructing new PUF structures based on the control of the signal propagation delay. It is shown that the signal delay through the basic element, which is a multi-input XOR element, depends not only on the number of inputs to which the active input signal is applied, but also on fixed values of 0 or 1 at its other inputs. A new PUF structure is presented, namely, a controlled ring oscillator, its implementation is considered for the case of control by setting the inputs and their number, by which the active input signal changes.Co n c l u s i o n. The proposed new approach to the construction of physically uncloneable functions, based on the control of signal delay through logical elements, has shown its efficiency and promise. The effect of the influence on the delays of signal propagation through the logic element, both the number of its inputs, along which the input signals change, leading to a change in the output signal, and their composition, is experimentally confirmed. It seems promising to further developing the ideas of constructing controlled ring oscillators and oscillators with multi-input switching of input signal, as well as the creation of new PUF structures of arbiter type.

Abstract
We present optical and near-infrared photometric and spectroscopic observations of the fast-declining Type Ia supernova (SN) 2015bo. SN 2015bo is underluminous (M

B
= −17.50 ± 0.15 mag) and has a fast-evolving light curve (Δm15(B) = 1.91 ± 0.01 mag and s
BV = 0.48 ± 0.01). It has a unique morphology in the observed V − r color curve, where it is bluer than all other supernovae (SNe) in the comparison sample. A 56Ni mass of 0.17 ± 0.03 M
⊙ was derived from the peak bolometric luminosity, which is consistent with its location on the luminosity–width relation. Spectroscopically, SN 2015bo is a cool SN in the Branch classification scheme. The velocity evolution measured from spectral features is consistent with 1991bg-like SNe. SN 2015bo has a SN twin (similar spectra) and sibling (same host galaxy), SN 1997cn. Distance moduli of μ = 34.33 ± 0.01 (stat) ±0.11 (sys) mag and μ = 34.34 ± 0.04 (stat) ± 0.12 (sys) mag are derived for SN 2015bo and SN 1997cn, respectively. These distances are consistent at the 0.06σ level with each other, and they are also consistent with distances derived using surface-brightness fluctuations and redshift-corrected cosmology. This suggests that fast-declining SNe could be accurate distance indicators, which should not be excluded from future cosmological analyses.

This study was conducted to elucidate the effects of rearing conditions on the composition of different phospholipid (PLs) classes and triacylglycerols (TAG) of the thick-lipped grey mullet (Chelon labrosus), a muscle originating from seawater and geothermal water. The major fatty acids in the examined lipid classes of the two fish groups were palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1n-9), linoleic acid (C18:2n-6), arachidonic acid (C20:4n-6), eicosapentaenoic acid (C20:5n-3), and docosahexaenoic acid (C22:6n-3). The analyses demonstrated that the fatty acid profiles of the PL classes in the seawater fish group were characterized by the predominance of n-3 polyunsaturated fatty acids (PUFA). By contrast, in geothermal fish, the distribution of PUFA series proportions differed between the phospholipid fractions. It was found PUFA n-3 was particularly abundant in PS and PI, while the n-6 series dominated the PC and PE PUFA group. Nonetheless, it was found that neutral lipid fatty acids were characterized by saturated fatty acids (SFA) followed by monounsaturated fatty acids (MUFA) in the seawater fish and by PUFA in the geothermal fish. The results presented here give useful information on the role of lipid classes in the physiological adaptation of C. labrosus which can serve for the optiminzation of these aquaculture systems.

Se ha estudiado el comportamiento tribológico de materiales compuestos de matriz metálica de aluminio (AA5083)/nano-Al2O3 con un porcentaje de refuerzo variable de 2, 4, 6 y 8% en peso de partículas de nano-Al2O3. Los compuestos Al/nano-Al2O3 se prepararon utilizando una ruta de colada por agitación. Las imágenes de microscopía electrónica de barrido (MEB) de los materiales sugirieron una dispersión casi uniforme de las nanopartículas en la matriz de Al. El comportamiento al desgaste por deslizamiento se estudió utilizando un banco de pruebas pin-on-disc. El plan de experimentos tuvo como referencia la matriz ortogonal L25 de Taguchi utilizando tres parámetros de proceso en cinco niveles, a saber, porcentaje en peso de refuerzo, carga aplicada y distancia de deslizamiento. Los resultados obtenidos revelan que los materiales compuestos reforzados con nanopartículas presentan una mejor resistencia al desgaste. Mientras que la gráfica de efectos principales sugirió que el desgaste aumenta con un aumento en la carga, la distancia de deslizamiento y disminuye con un aumento en el porcentaje de refuerzo. El análisis de varianza (ANOVA) ilustró que la distancia de deslizamiento fue el parámetro más significativo. La morfología de la superficie desgastada del espécimen probado, bajo la condición de carga más alta, reveló la ocurrencia de un fenómeno de desgaste abrasivo.

Published: March 2022

Com o crescente interesse público pela questão do autismo, assistimos a uma torção importante do debate que caracteriza esse tema. Inicialmente reduzida ao campo científico – em geral médico – a questão do autismo se viu progressivamente encampada por diferentes agentes, sobretudo pelos próprios autistas, cujas contribuições ampliaram muito o que podemos saber hoje sobre o autismo. Com o termo narrativas do autismo, tivemos como proposta neste artigo demonstrar a riqueza dos aportes desses novos saberes para o debate científico e político sobre a questão, bem como demonstrar o risco dela permanecer encapsulada e restrita ao campo estritamente científico. Para tanto, passamos pela história do conceito ressaltando como nela se pode ver o quanto o percurso científico vai sendo afetado, enriquecido por influência desses outros agentes e o valor de se tomar em consideração as diversas narrativas sobre o autismo. Situar a diversidade dessas narrativas não tem como objetivo apenas retomar uma posição plural e aberta contra outra exclusiva e restritiva, mas, antes, de colocar em curso o que pode acontecer ao debate científico quando ele não se fecha demasiadamente sobre a tendência objetivante própria a organização do discurso científico.

The first and foremost aim of Ayurveda - “Swasthasya Swasthya Rakshanam Aaturasya Vikara Prashamanam Cha” is to maintain a healthy state of life and to remain free from the burden of diseases and sufferings so as to accomplish the ultimate goal of human life. To achieve this objective, Ayurveda has advocated certain percepts and rules which can ensure the normal functioning of human body without any hindrance. Ayurveda has suggested schedules of Swasthvritta including Dincharya, Ratricharya, Ritucharya, Rasayana, and Sadvritta as some of the practices and methods that leads to a happy, healthy and long life. In Ayurveda general principles to prevent psychic disturbances, practices preventing psychosomatic disturbances, practices regarding codes of general ethics in diet, behaviour, study, self-control etc. are explained as parts of Sadvritta. True efforts made for the observation of these schedules and conduct give rise to the effects of rejuvenation therapy called Aachar Rasayana that promotes longevity without any attack of diseases. Rasayana is one of the comprehensive disciplines of Ayurveda, which comprises a specialized use of herbs, herbo-mineral formulations, food articles and lifestyle along with self-discipline with social etiquette to achieve the optimum state of tissues that there is least effect of etiological factors on body. A careful analysis of qualities of Aachar Rasayana reveals that most of them are related to Mana, Dhi, Dhriti, along with good conduct. It inculcates the discipline related to mind, character, social, religious and personal life, so as to accord with the happiness and good of the individual and the society as a whole.

Drug use monitoring in Australia: Drug use among police detainees, 2021
Authors: Voce Alexandra , Sullivan Tom 
Published: March 2022

In 2021 the Drug Use Monitoring in Australia program collected survey (n=2,223) and urinalysis (n=716) data from police detainees across Australia. Seventy-seven percent (n=553) of detainees who provided a urine sample for analysis tested positive to at least one type of drug, less than in 2020 (82%). Around half of the detainees tested positive to methamphetamine (50%) or cannabis (45%), one-fifth tested positive to benzodiazepines (18%) or opioids (18%), whereas very few tested positive for cocaine (2%) or MDMA (<1%). Self-reported past-month methamphetamine use was stable for most of 2021 until it declined in October–November, while past-month cannabis use increased in July–August. Nationally, methamphetamine and heroin each cost $50 per point on average, whereas cannabis cost $17 per gram.

Coastal groundwater is extremely vulnerable to land-based human activities and seawater intrusion. In Brazil, a developing country, several coastal cities are undergoing recent urbanization with no planning, giving rise to problems such as groundwater overexploitation, sanitation, and chemical contamination. This study provides seasonal and spatial groundwater chemical and microbiological characterization of a recently urbanized coastal region, discussing contamination and salinization. The recent urbanization event affected both shallow and deep wells represented by the extensive presence of Escherichia coli on groundwater and nitrate, ammonium, arsenic, and lead (NO3-, NH4+, As and Pb) levels above groundwater safety guidelines. In contrast, iron and manganese (Fe and Mn) concentrations above the safety limit were associated with lithological enrichment, but might also restrict groundwater consumption. In addition to chemical and microbiological contamination, salinization of coastal aquifers did not pose a threat in this shoreline, but brackish groundwater was found in one well influenced by a coastal lagoon sandbar opening that allowed seawater to enter the aquifer.
Vinculación Docencia y Extensión: Experiencia de la Universidad Abierta para Adultos, República Dominicana
Authors: Tavárez Ana , Ventura Pedro Emilio 
Published: March 2022

La Universidad como institución social enarbola tres funciones sustantivas: la docencia, la investigación y la extensión. Estos pilares permiten articular el quehacer académico e institucional para lograr la concreción de la filosofía que justifica su razón de ser. En el caso de la Universidad Abierta para Adultos, además de las tres funciones anteriores, se contempla también la gestión, la cual es concebida como el conjunto de acciones desarrolladas por el personal académico y administrativo para garantizar la calidad de los procesos educativos. A pesar de la declaración de las funciones sustantivas como parte inherente, las prácticas que sustentan el modelo de la universidad representan un gran reto para desarrollar acciones puntuales que den cuenta de la articulación entre la docencia y la extensión.
A partir de esa inquietud se ha concebido un plan que impulse esa dualidad desde el desarrollo de la docencia, más concretamente en la práctica docente. Es de gran interés para la académica concebir actividades que permitan fusionar las funciones sustantivas del quehacer universitario a través de la planificación y puesta en marcha de estrategias de enseñanza y aprendizaje.
De esta motivación surge la propuesta de abrazar la docencia y la extensión en una buena práctica didáctica durante el desarrollo de las asignaturas que cursan los participantes de la UAPA. El objetivo se caminó a compartir la experiencia de la UAPA respecto a la vinculación social y compromiso comunitario con la participación de la comunidad universitaria.
Cátedra de la Tierra “Dr. Gonzalo Cruz Calderón”, un programa educativo de conciencia ambiental y de extensión universitaria
Authors: Ortega Ramos Yeceisky Yajerik 
Published: March 2022

La Cátedra de la Tierra, “Dr. Gonzalo Cruz Calderón”, del Departamento de Ciencias Naturales de la Universidad Pedagógica Nacional Francisco Morazán (UPNFM), es una estrategia educativa institucional que incluye una amplia gama de divulgación del conocimiento científico y la realización de acciones prácticas (investigaciones, trabajos de campo, campañas en línea, seminarios, conferencias, trabajos de laboratorio, recolección de muestras geológicas, entre otros), para fortalecer una conciencia proactiva hacia el equilibrio del planeta tierra a través de la planificación y ejecución de dichas actividades en los diferentes programas académicos de la universidad (pregrado y programas especiales).
El programa educativo persigue el mejoramiento de las condiciones ambientales y de desarrollo sostenible en todas las sedes universitarias del país de la UPNFM, introduciendo y trabajando con una variedad de metodologías apropiadas para tal fin, en el contexto del sistema educativo universitario (metodologías presenciales, a distancia y virtual). El programa se fundamenta en el principio y lema universitario de “Educar para transformar”, concibiendo y proponiendo a través de la educación, la más eficiente y perdurable intervención hacía el logro y consolidación de una conciencia que asegure la sostenibilidad y el equilibrio del planeta tierra.
En ese sentido, mediante dicho programa educativo, entre la sétima u octava semana de cada período académico universitario desde el año 2012, se planifica y genera una serie de actividades gestoras del proceso de sensibilización ambiental, las cuales a su vez son conformadas y ejecutadas por educandos, personal docente y personal administrativo del área de ciencias naturales de la universidad, pero como una extensión y vinculación social del departamento hacia el resto de la comunidad universitaria, son beneficiarios de dicho conocimiento y sensibilización ambiental los educandos de todas las distintas facultades, carreras y sedes donde funciona la UPNFM. Asimismo, se describen algunas experiencias obtenidas en el desarrollo y crecimiento de este importante programa educativo.
