Authors: Venegas S. S. , Herrera F. J. J. , Maciel F. R.
Published: May 2021

La integración de los trabajos geológicos realizados en la Faja Volcánica Mexicana (FVM) denominación adoptada en este trabajo para el Eje Neovolcánico - se ha efectuado con el fin de analizar las características e interpretaciones geológicas que sobre esta provincia se han hecho, así como proporcionar una visión más amplia de los aspectos geotérmicos involucrados en ella. Se presenta una discusión sobre la relación vulcano-tectónica ocurrida desde el inicio del desarrollo de la FVM y el posible origen y características de su basamento, apoyándose en la información de subsuelo dada por los pozos geotérmicos, la geología regional y dataciones tanto de subsuelo como superficiales. Se analiza, además, la correlación y posición de la Faja con respecto a la Sierra Madre Occidental, concluyéndose que el basamento de aquélla es diferente de ésta. Como resultado de lo anterior, y desde un punto de vista geotérmico, se subdivide y jerarquiza en 10 sectores la provincia de la FVM. Finalmente se describe la asociación del potencial geotérmico presente con la actividad vulcano-tectónica reciente, así como con las cámaras magmáticas someras.
Momentum flux of the solar wind near planetary magnetospheres: a comparative study
Authors: Pérez de Tejada H.
Published: May 2021

Se presenta un estudio del perfil Je velocidad del viento solar exterior a las magnetosferas de laTierra, Marte y Venus. Existe una diferencia característica en las condiciones presentes en planetas con magnetización interna alta y débil. En el caso de un planeta fuertemente magnetizado, como lo es la Tierra, la velocidad del viento solar cerca de la magnetopausa se mantiene aproximadamente constante en la dirección normal a esa frontera. En planetas de baja magnetización (Venus, Marte) el perfil de velocidad muestra, cerca de la magnetoionopausa, un gradiente transversal el cual implica una reducción efectiva del flujo de momento del viento solar en esa región. El diferente comportamiento del viento solar en la vecindad de cada planeta es examinado en conexión con el proceso de interacción que opera en su frontera magnetosférica.
Late mesozoic-cenozoic evolution of the Northwestern Mexico magmatic arc zone
Authors: Urrutia-Fucugauchi Jaime
Published: May 2021

Los datos radiométricos de rocas ígneas del Mesozoico tardío - Cenozoico de la provincia magmática del noroeste de México se emplean para estudiar la evolución tectónica del margen continental. Los resultados indican que la actividad magmática ha cambiado su posición con el tiempo, desde ~140 ma al presente. Entre los 140 y 60 ma, la distancia arco magrnático - trinchera se incrementó desde 100 a 400 km, con una velocidad entre 1 y 12 cm/año. El área cubierta por el material ígneo se incrementó hasta ~540 km, lo que combinado con los cambios en la distancia arco - trinchera, resultó en un arco magmático espacial de ~1 200 km. Los magmas fueron predominantemente calco-alcalinos y la tectónica fue compresiona. Entre ~60 y ~JO ma, la actividad magmática se desarrolló en localidades alejadas de la trinchera, con rocas calco-alcalinas de alto potasio y alcalinas. La tectónica cambió de compresiva (orogenia Laramide, ~so a 45 ma) a extensiva (orogenia del Terciario medio, ~35 – 15 ma). Finalmente, entre 35 - 30 y 10 -O ma, la actividad magmática se desplazó rápidamente hacia la trinchera y la tectónica fue extensiva. El volcanismo fue bimodal e incluyó el emplazamiento de secuencias ignimbríticas. En este intervalo ocurrió una reorganización en las relaciones de placas litosféricas que incluyó el encuentro de segmentos de la dorsal con la trinchera y la generación de fallas transformadas. El Golfo de California comenzó a desarrollarse y se incrementaron fases activas de esparcimiento del fondo oceánico en los últimos 4.5 m.a. Los cambios observados en la distancia arco-trinchera y en el ancho de la zona de manifestaciones magmáticas se interpretan con un modelo de ángulo de subducción variable y de profundidad y rango de generación de magma variable. Los factores principales involucrados fueron el cambio de edad de la placa oceánica (paulatinamente más joven), cocientes de convergencia de placa, abducción de corteza oceánica, subducción de altos batimétricos y extensión tectónica.

Se analiza un método numérico directo de reducción cíclica para resolver ecuaciones de tipo elíptico. Al aplicar el método citado a la ecuación de verticidad no-divergente y al introducir el Jacobiano de Arakawa, el Laplaciano truncado a cuarto orden y condiciones a la frontera reales, los resultados muestran un mayor alcance en el tiempo de pronóstico.
Estructura de la corteza al oriente de la Sierra Madre Occidental, México, basada en la velocidad de grupo de las ondas de Rayleigh
Authors: Rivera J. , Ponce L.
Published: May 2021

Se usa la dispersión de las ondas de Rayleigh en su modo fundamental, correspondiente a dos explosiones nucleares efectuadas en Nevada, USA, y registradas en la estación sismológica UNM, en la ciudad de México, para estimar la estructura de la velocidad de la onda de cizalle en un perfil que corre aproximadamente a lo largo del flanco oriental de la Sierra Madre Occidental, México. Los datos observados de la dispersión de la velocidad de grupo para el rango de períodos de 10 a 21 segundos pueden explicarse con 5 capas horizontales, elásticas y homogéneas sobre un semi espacio. El espesor promedio obtenido para la corteza es del orden de 40 km. Las velocidades de cizalle y los espesores obtenidos son los siguientes: Sedimentos, Vs1 = 1.5 km/s, h1 = 1.2 km; Granito, Vs2 = 2.90 km/s h2 = 2.2 km y Vs3 = 3.56 km/s, h 3 = 26 km; Basalto, Vs4= 4.10 km/s, h4= 10.0 km; Manto Superior Vs5 = 4.50 km/s, hs = 10.0 km; Manto, Vs6=4.15 km/s, h6= ∞. Se presupone una razón de 1.78 para el cociente Vp/Vs. Este modelo de velocidades sugiere que la estructura del flanco oriental de la Sierra Madre Occidental es transicional entre una de tipo Alpino y otra de tipo Basin and Range. El modelo concuerda satisfactoriamente con resultados anteriores basados en estudios de refracción hechos en los alrededores de la región y con las ideas sobre la evolución tectónica cenozoica del oeste del continente norteamericano.
La Cuenca paranaense. Influencia de los basaltos en la interpretación gravimétrica
Authors: Introcaso A. , Gerster R.
Published: May 2021

La cuenca del Paraná fue durante el Cretácico Temprano- Jurásico Tardío, testigo de erupciones de lavas no explosivas que cubrieron gran parte de la cuenca, en numerosas camadas interestratificadas. Frecuentemente los espesores de las coladas superan los 80 m, mientras que el conjunto de derrames alcanza aproximadamente los 1 000 m en Salto (Uruguay). La máxima distancia recorrida por las lavas desde el foco de derrame fue estimada en 100 km, consistente con la escasa pendiente regional admitida. Pensamos así, que esta excepcional manifestación volcánica (más importante que la de la India) es un fenómeno regional integrado por numerosos eventos locales interrelacionados. Los estudios gravimétricos señalan la probable existencia de cuerpos subvolcánicos que son interpretados como antiguas cámaras magmáticas. Fueron analizados diversos modelos gravimétricos demostrando que masas intracorticales de alta densidad vinculadas con los episodios efusivos pueden justificar la gravedad observada.
Palaeomagnetic study of mesozoic rocks from Ixtapan de la Sal, México
Authors: Urrutia Fucugauchi J. , Valencio D. A.
Published: May 2021

Se reportan datos paleomagnéticos para 25 muestras de tres localidades de una secuencia de rocas metavolcánicas expuestas en el área de Ixtapan de la Sal, México. Las muestras presentan grados variables de alteración hidrotermal y metamorfismo, con dos sitios de esquistos verdes y un sitio de andesitas alteradas. Las muestras fueron sometidas a tratamiento con campos magnéticos alternos decrecientes y con altas temperaturas. Las direcciones tienen polaridades normal y reversa, son estables con la desmagnetización y proporcionan una posición polar media de 54.1°N, 139.1°E (dp = 10°, dm = 7°). Las magnetizaciones son llevadas por minerales magnéticos de alta coercitividad, posiblemente hematita secundaria. Dataciones radiométricas de K-Aren muestras de dos sitios dan edades de 108 ± 5 ma y 125 ± 5 ma, las cuales se relacionan con el evento de compresión y alteración regional que afecto la zona. Se sugiere que las magnetizaciones remanentes observadas fueron adquiridas durante el Jurásico tardio o Cretácico tardio. La posición polar derivada de las rocas metavolcánicas diverge de otros polos paleomagnéticos reportados para otras áreas de México del Mesozoico, lo que sugiere la posible ocurrencia de movimientos tectónicos de esta área.

Published: May 2021

Aims: To develop a pharmaceutical consultation mode of multidisciplinary
individualized medication recommendations, to improve the quantity and
quality of clinical pharmacists’ consultations Methods: A retrospective
study of 542 clinical pharmacists-led consultations was conducted. In
the pre-intervention group, medication advice was given based on the
purpose of the consultation. In the post-intervention group, a
consultation mode of multidisciplinary individualized medication
recommendation was implemented, in which clinical pharmacists with
specialties of anticoagulation, gastroenterology and nutrition were
asked to give individualized medication recommendations and a set of
evaluation criteria for rational drug use was formulated. Outcomes,
including the patterns and number of consultations, individualized
medication recommendations, acceptance rate and effectiveness rate, were
compared between the two periods. Results: A total of 651 cases were
reviewed, and 542 cases of which meeting the predesigned inclusion and
exclusion criteria were included, with 94 and 448 patients in the
pre-intervention and post-intervention groups, respectively. The total
number of consultations increased year by year, so did the number of
general consultations, multidisciplinary difficult consultations,
departments applying for general consultations, departments applying for
multidisciplinary difficult consultations, anti-infection consultations
and non-anti-infection consultations in details. The effectiveness rate
of consultations in the post-intervention group was 81.7% vs 70.2% in
the pre-intervention group (P < 0.05). No difference was shown
between two groups in acceptance rate (96.9% vs 95.7%, p=0.578).
Federated Learning Versus Classical Machine Learning: A Convergence Comparison
Authors: Asad Muhammad , Moustafa Ahmed , Ito Takayuki
Published: May 2021

In the past few decades, machine learning has revolutionized data processing for large scale applications. Simultaneously , increasing privacy threats in trending applications led to the redesign of classical data training models. In particular, classical machine learning involves centralized data training, where the data is gathered, and the entire training process executes at the central server. Despite significant convergence, this training involves several privacy threats on participants’ data when shared with the central cloud server. To this end, federated learning has achieved significant importance over distributed data training. In particular, the federated learning allows participants to collaboratively train the local models on local data without revealing their sensitive information to the central cloud server. In this paper, we perform a convergence comparison between classical machine learning and federated learning on two publicly available datasets, namely, logistic-regression-MNIST dataset and image-classification-CIFAR-10 dataset. The simulation results demonstrate that federated learning achieves higher convergence within limited communication rounds while maintaining participants’ anonymity. We hope that this research will show the benefits and help federated learning to be implemented widely.
Narcolepsy with Cataplexy: What we know about it in 2021
Authors: Diamandis Dr. Carolina , Seideman David , Adams Jacob S
Published: May 2021

Narcolepsy is a model disease for many sleep-wake disorders, a
dyssomnia. Diagnostically important is the so-called “narcoleptic
tetrad”: Daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic
hallucinations. Common differential diagnoses are epilepsy, psychoses,
pharmacological influences and sleep disorders. The correct diagnosis is
often made too late. Often, negative psychosocial consequences of
narcolepsy have already occurred for the patients in the meantime, which
can be prevented by an early diagnosis. Therefore, the objective of this
White Paper is to raise more awareness in the medical community.

Published: May 2021

Hybridization is an important part of species evolution. The hybrid
progeny population had rich genetic and phenotypic variation, which made
the boundaries between them and their parents blurred and difficult to
distinguish. There was little research on the origin of natural hybrids
of Triticeae. In this study, we found a large number of putative hybrids
of Roegneria in West Sichuan Plateau, China. The hybrid plants showed
strong heterosis in plant height, tiller number and floret number.
Morphologically, the putative hybrids showed intermediate of Roegneria
stricta Keng and Roegneria turczaninovii (Drob.) Nevski. Hybrids had 28
chromosomes corresponding to that of R. stricta and R. turczaninovii
(2n=4x=28). Meiotic pairing in hybrids were less regular than those of
R. stricta and R. turczaninovii. GISH analysis showed that the hybrid
plants had the same genome as that of R. stricta and R. turczaninovii
(StY). Phylogenetic analysis based on the single copy nuclear gene DMC1
and chloroplast gene rps16 showed the plants were closely related to R.
stricta and R. turczaninovii. This study indicated that the plants were
hybrids of R. stricta and R. turczaninovii. The results provided data
for the utilization of hybrid. This study provided a case study of
natural hybrids.

Augmentation of convection heat transfer from a horizontal cylinder in a vented square enclosure with variation of lower opening size
Authors: Ali Omar , Mahmood Raid , Al-Brifkani Mohammed
Published: May 2021

Natural and mixed convection heat transfer from a horizontal cylinder placed in a vented square enclosure has been investigated using numerical method with ANSYS Fluent 16.1 software for laminar and turbulent flow. Navier-Stokes equations and energy equation with standard k-? transport equation turbulence model have been used to simulate both flow and thermal behaviors. The operating conditions covered a range of the Rayleigh number from 103 to 106 and the Richardson number range between 0.1 and 100 at variable sizes of the lower open vent with constant upper opening size. The Nusselt numbers, velocity lines and isotherms are presented to display the flow and thermal behaviors. The results displayed that the average Nusselt number is affected by Rayleigh number, Richardson number, enclosure width, and lower opening size. The Nusselt number is enhanced by controlling the lower opening size. The maximum enhancement range for Nusselt number is between 20-85% depending on the Rayleigh number, Richardson number, enclosure width to cylinder diameter, and lower opening size. The velocity lines and isotherms are directly affected by the Rayleigh number, Richardson number, enclosure width to cylinder diameter, and lower opening size.
CALLING THE POLICE AS DISPROPORTIONATE FORCE
Authors: Husak Douglas
Published: May 2021

Persons who dial 911 are often able to foresee that the subsequent levels of force police employ will be excessive, disproportionate, and therefore wrongful. This might seem to justify the provocative thesis that persons who call the police against suspected unlawful aggressors act impermissibly and deserve some quantum of blame for what they have done. In this paper, I critically examine and ultimately reject this thesis and discuss several possible grounds on which it might be false.
Preparing Auditors for the Blockchain Oracle Problem
Authors: Sheldon Mark D.
Published: May 2021

This article summarizes “Auditing the Blockchain Oracle Problem” (Sheldon 2021), which introduces auditors to the risks of having an irreversible business agreement codified on a blockchain using a short software program called a smart contract that relies on an oracle to provide information from outside the blockchain in order to execute correctly. The article begins with an explanation of the role that oracles play in the blockchain ecosystem and proposes a working definition of oracles. Next, the article highlights how the auditing standards from both the AICPA and PCAOB can be interpreted to classify an oracle as part of smart contract users' information systems, and that the oracle provides a robust set of services that qualify it as a service organization. Finally, the article describes the process used by an oracle to collect, store, transform, and transmit data, and highlights relevant risks and illustrative control objectives related to this process.
Computational modeling and damage threshold prediction of continuous-wave and multiple-pulse porcine skin laser exposures at 1070 nm

Published: May 2021

Computational models are capable of simulating the expected thermal response of biological tissue to laser irradiation. A typical laser tissue model accounts for optical energy deposition, heat transfer, and damage assessment, with the latter often represented by calculation of the Arrhenius integral. Previous studies have successfully employed these methods to predict skin damage thresholds at laser wavelengths with high absorption in water, and usually for single continuous-wave exposures. However, there remains a need for a robust and accurate predictive model in low-absorption, high-scattering cases, such as for exposures in the near-infrared region near 1000 nm. This study presents a framework for modeling laser irradiation of skin tissue at 1070 nm for both continuous-wave and pulsed exposures with durations ranging from 10−2 to 101 s. The authors derive an optical absorption coefficient for the epidermis that agrees with expected chromophore distribution and report the modeled skin thermal responses alongside surface thermography data from in vivo porcine exposures as validation of simulation accuracy. Comparisons of modeled damage thresholds calculated by the Arrhenius integral with documented experimentally determined minimum visible lesion ED50 data exhibit a high degree of agreement. The authors also provide new Arrhenius rate process coefficients of A = 2.74 × 1094 s−1 and Ea = 5.90 × 105 J/mol, determined from experimental thermal profiles with a unique method, that demonstrate more accurate threshold predictions than those used in previous modeling studies. The techniques outlined by this study provide a useful tool in assessing potentially hazardous near-infrared laser exposure scenarios.

Assessment practices promoting learning at the lower secondary level: Findings from TALIS 2018 and the LISA project

This chapter presents some of the results from the Norwegian TALIS 2018 survey related to professional knowledge, competence, and practice. Findings from teachers’ reporting on their own teaching practices are highlighted, specifically the part of their teaching that deals with assessment practices. Results from the TALIS survey are then interpreted in light of the results from a research project that deals with the same topic with other data sources.

The Linking Instruction and Student Achievement project (LISA) combines video data from teaching practices in language arts and mathematics at the lower secondary level with test results from national tests (reading and arithmetic) from the same classes from which the observation data were taken. LISA is the largest video study of its kind of classroom practices in the Nordic countries and is a suitable frame of interpretation for TALIS 2018 data, as all data materials are linked to the last period of the former national curriculum in Norway. Findings from TALIS 2018 show that there could have been far more teachers who checked that the feedback they provide on written assignments is understood by their students. Results from the LISA project confirms this finding and also show that quite a few teachers are responsible for a large part of the feedback that is regarded to be of high quality. The chapter indicates that there is great potential for working more collectively on this topic both in the teacher education stage and as part of a well-managed lifelong learning system for teachers.
Implementation of Heart and Dematel Integration to Steam Boiler Working Process
Authors: Feryal Can Gülin
Published: May 2021

Human Error Assessment and Reduction Technique (HEART) is a practical and powerful approach to prioritize errors related to human actions, based on probabilities. HEART can determine error producing conditions (EPCs) which cause human errors for different processes including main duties (MDs) and sub-duties (SDs). HEART can be applied quickly for any process where human reliability is important. In this study, HEART and advanced version of Decision Making Trial and Evaluation Laboratory (AV-DEMATEL) integration proposed by Can and Delice in 2018 was performed for evaluating human related errors in steam boiler working process. In this way, the interactions between MDs, SDs and EPCs in a steam boiler working process were considered to compute process error probability (PEP). Additionally, the applicability of the proposed approach by Can and Delice (2018) was demonstrated again.

Published: May 2021

A two-stage path needs analysis model aimed at determining the professional development needs of school administrators and teachers working in Turkey and to what extent they needed these trainings was reported in this study. First, the nominal group technique was implemented. Second, according to the results, the professional development training needs were turned into targeted surveys for each participant group. The school administrators needed leadership; pre-school teachers needed picture analysis; primary school teachers needed creative drama; middle-school teachers needed integration with the digital world; high-school teachers needed first-aid; special education teachers needed techniques for changing problematic behaviors, and guidance/psychological counseling teachers needed solution-oriented therapy training. It was shown in the findings that the nominal group study results and the surveys differed for all groups. As a conclusion, a single need analysis approach was insufficient for identifying professional development needs and it is necessary to utilize one or more techniques together.

Formas de (des)afección: Dos veces junio de Martín Kohan
Authors: Mandolessi Silvana
Published: May 2021

Este artículo analiza la novela Dos veces junio (2002) de Martín Kohan desde la teoría de los afectos. El narrador de Dos veces junio se caracteriza por la ausencia, la suspensión, la vacilación o la supresión de afectos. Asumiendo que las respuestas afectivas corresponden necesariamente al momento histórico y a la esfera de la cual emergen, el artículo explora esta desafección como un componente esencial del funcionamiento del régimen autoritario que la novela retrata. Así, se sostiene que el afecto es no solo esencial para iluminar una época histórica sino la manera en que el pasado pervive en el presente ya que las inscripciones afectivas son las depositarias del sentido más oculto –y más original– de la memoria.
Reinstitucionalización del testimonio en América Latina desde la narrativa humanitaria

Proponemos explorar la tradición del testimonio latinoamericano marcando dos modelos. En primer lugar, revisamos el testimonio de matriz revolucionaria, institucionalizado en 1970 por Casa de las Américas bajo el paradigma revolucionario y en cuyo interior analizamos tres tipos diferentes –el testimonio etnográfico, guerrillero y periodístico–. En segundo lugar abordamos la reinstitucionalización del testimonio bajo la narrativa de los Derechos Humanos hacia la década del 1980, focalizando en el caso Argentino. Nos interesa indagar los estatutos de cada modelo así como sus vínculos con el campo literario.
Violencia, memoria y género. Gabriela Cabezón Cámara, Marta Dillon, Selva Almada, Luciana de Mello, Belén López Peiró

Published: May 2021

Avanzada la primera década del 2000 en efecto, va visualizándose la conformación de una zona narrativa que ligada a la inmediatez del presente de su enunciación (el conjunto de fuerzas sociales y discursivas en torno a cuestiones de género y diversidad) va tejiendo nudos entre los imaginarios de violencia patriarcal desplegados en los textos y el universo de hechos y relatos setentistas, entre perspectiva de género y terrorismo de estado. Recorremos aquí en algunas variantes de narrativas testimoniales (ficcionales y de carácter autobiográfico) estos cruces y articulaciones que, ya presentes en Le viste la cara a Dios (2011) de Gabriela Cabezón Cámara, se replantean de otros modos en Aparecida (2015) de Marta Dillon y Chicas muertas (2014) de Selva Almada y pueden rastrearse también en las nuevas hablas del abuso representadas por Mandinga de amor (2016) de Luciana De Mello y Porqué volvías cada verano (2018) de Belén López Peiró.

Published: May 2021

Este estudo teve o objetivo de analisar a moeda social como alternativa econômica regional considerando o seu potencial, na qualidade de tecnologia social, para o desenvolvimento local, além de atuar como viabilizadora e promotora do protagonismo, autonomia, emancipação, gestão democrática e empoderamento dos sujeitos e das comunidades frente aos desafios e tensões econômico-comerciais enfrentadas por determinadas comunidades nas relações econômicas tradicionais e convencionais. Realizou-se um resgate bibliográfico histórico-conceitual na literatura especializada, seguida de uma metodologia descritiva e levantamento da produção científica, que abordou os aspectos e estruturas que compõem a moeda social, suas particularidades e utilizações. Logo após, procedeu-se com um estudo de caso sobre a moeda social de Palma, considerada a primeira moeda social do Brasil, criada e utilizada pelo Conjunto Palmeiras, bairro periférico da cidade de Fortaleza-CE, de modo a compreender as particularidades da apropriação e utilização da moeda no mundo real. Como resultados, identificou-se: a) a necessidade de uma regulamentação das moedas sociais por parte do Estado brasileiro; b) os impactos econômicos positivos para a comunidade usuária da moeda; c) um paradoxo entre a legitimidade e o desuso da moeda.

Influência do benefício de prestação continuada sobre a taxa de pobreza dos idosos nos munícipios mineiros no período 2014-2017
Authors: Souza Letícia Pereira de , Teixeira Evandro Camargos , Tupy Igor Santos
Published: May 2021

A pobreza e o envelhecimento no Brasil têm sido alvo de pesquisas no âmbito da Economia, pois a existência de idosos desprotegidos e vivendo em situação de miséria é uma realidade no país. Nessa perspectiva, este trabalho tem como principal objetivo analisar a relação entre as transferências do Benefício de Prestação Continuada (BPC) e o percentual de pessoas idosas pobres e extremamente pobres registradas no Cadastro Único. Para analisar essa relação, foram utilizados dados do Índice Mineiro de Responsabilidade Social (IMRS), considerando o período de 2014 a 2017 para os municípios do estado de Minas Gerais. Ao estimar o modelo econométrico com dados em painel dinâmico, a pesquisa encontrou evidências indicativas de que o BPC contribui para redução da pobreza idosa. A literatura denota que os principais mecanismos que explicam esse efeito estão relacionados ao fato de que o programa lida com quadros em que já há pobreza instaurada e, por isso, funciona como uma garantia regular de obtenção de renda aos idosos e até mesmo aos seus familiares.

Objective: The aim of this paper was to describe the anthropometric and physiological characteristics of young soccer players (U13) which were associated with their being successful or not as soccer players, and also to determine standard levels in the light of a test battery and indicators to select and guide the young talents as a scientific means to facilitate the selection. Method: A total of 390 soccer players age (U13). From 14 Algerian soccer clubs were enrolled and subjected to standard anthropometric, fitness (speed 20m, CMJ, skills-related performance testing. The testing battery will be described as will the process for converting test data into standardized scores. Data will be presented to show the strengths and weaknesses of some players. Result: After analysing the results based on the standard criteria for the proposed tests as well as the overall performance variable. And the ability of each youth to be selected according to their potential, and therefore it was stressed that the proposed criteria, which are scientific support for the field observation, should be emphasized to facilitate this process for Algerian soccer players. The findings from this study indicate that marked improvements and parameters associated with physical maturity such as height, weight, speed, VO2max, or chronological age are important to determine the success of a soccer player. At older ages, other factors such as agility seem to be more important. Nevertheless, players born in the 1st semester of the year are also more frequent in the older teams. These findings should be taken into account by trainers and coaches in order to avoid biasing their selection choices.

60 m hurdles races are included in the World Indoor Athletics Championships and consist the shortest hurdle race distance. Thus, it is possible that the reaction time (RT) affects the finish time (t60mH) and the rank of the hurdlers. The aims of this research were: a) to examine the relationship between RT and t60mH, b) the possible differentiation of RT: c) between the hurdlers who won a medal in World Indoor Athletics Championships (WM) and those who did not (NMW), d) between hurdlers who competed before (BRC) and after (ARC) the change of the starting rules in 2009. Analysis included 70 performances (WM: n = 28; NMW: n = 42; BRC: n = 32; ARC, n = 38). The differences between WM and NMW and BRC and ARC were examined with independent samples T-test, while the possible relationship between RT and t60mH with Pearson’s correlation. The results showed that RT was not significantly different (p < .05) between WM and NMW and between BRC and ARC. A weak, but significant, positive correlation (r = .228, p = .016) between RT and t60mH was observed. Results revealed that RT is a factor that affects t60mH. In conclusion, the essential focus on the reaction time at the starting blocks must be given during the training process.

Baicalin is a flavonoid that has an influence on molecular processes. It possesses anticancer, anti-inflammatory, antiviral, antioxidative, and antithrombotic properties. It was found that baicalein treatment attenuated the damage of the mammary gland induced by LPS, suppressed the activity of myeloperoxidase, TNFα, and IL-1β in mice with mastitis. The aim of the study was a pilot analysis of baicalin tolerability after intramammary (IMM) administration and its impact on somatic cell count (SCC) after multiple IMM treatment on dairy cows with clinical mastitis. Moreover, the determination of baicalin in milk was performed by the sensitive ultra-high performance liquid chromatography with tandem mass spectrometry. The pharmacokinetic analyses were performed using Phoenix® WinNonlin® 6.4 and ThothPro v 4.1 software. Twelve dairy cows with clinical mastitis were selected for this study. The pharmacodynamic endpoint was SCC level and the clinical investigation was also carried out. Baseline SCC analysis was performed every 24 h among all cows three days before the first dose (B1–B3). After the baseline monitoring, 8 days of treatment (T1–T8) was performed and 8 days within recovery period SCC level was observed (R1–R8). Starting from T1 to T8, a decrease of SCC in relation to baseline was characterized by a declining trend. The presented results confirm the effect of baicalin on the reduction of SCC in mastitis in dairy cows after this therapy. The current study has shown that baicalin accumulation was not confirmed.

Laboratory model is used in this study to investigate the behavior of centrally loaded square footing resting on gypseous soil, and surrounded by a sheet pile wall at a distance of 2B from the footing edge and extend in depth to 2B as well. During this study the soil were subjected to ten cycles of saturation and drainage at one-week interval to simulate heavy rainfalls or floods. It should be noted that the soaking water were added only outside the area surrounded by the sheet pile. Four points were chosen to detect gypsum solubility, three of them below the footing edge at different depths and one outside the sheet pile wall for comparison. It has been found that the dissolved gypsum below the footing is significantly less than the one outside the sheet pile wall. For each cycle of saturation-drainage the gypsum content is found to be reduced by 3 % and 0.8 % for the outsider point and for average of the three points respectively. Settlement during first cycle of saturation – drainage was twice as the second cycle and about four times of the third cycle. However, this first cycle settlement is about 25 % of the settlement of footing where no sheet pile wall is used. To sum up, the sheet pile wall found to be an effective protection to reduce the collapsibility of gypsum soil and to reduce footing settlement.

Published: May 2021

This paper mainly aims to provide in-depth research on how Croatian franchisors utilise the possibilities of the digital environment in terms of their digital presence. The main focus of digital presence analysis is set on franchisors’ official website and supporting communication channels. For research, this paper focused on creating and testing a specialised evaluation model. The proposed model is dominantly based on three applicable models (Martinez & Gauchi, 2010; Rao & Frazer, 2005; Stefanović & Stanković, 2014) and revised according to the situational factors. A redesigned model was used to evaluate websites of Croatian franchisors, mainly focusing on the provided information, website usability, communication possibilities, and promotional activities. This research paper offers two main outcomes. The first outcome is the redesigned evaluation model, which was applied and tested with several provided improvement guidelines. The second outcome is the comparative analysis of the selected Croatian franchisors in terms of their digital presence and its relationship to several market-related indicators. The paper presents a literature review on franchising e-presence worldwide. The research results presented in this paper offer a better insight into the use of websites by Croatian franchisors. Based on their use, certain conclusions can be made. Consequently, a contribution is made to theoretical research about franchising in Croatia and can serve as a framework for further research in the region. Based on the findings of this paper and the information provided by Croatian franchisors about their products and/or services to current and potential buyers, investments in websites result in wider franchising networks and greater success in the market.

Striving for smart mobility in Morocco: a case of lanes designated to heavy goods vehicles in Casablanca
Authors: Maaroufi Mohammed Mouhcine , Stour Laila , Agoumi Ali
Published: May 2021

This article highlights the need to rethink how to manage mobility in Morocco more intelligently, given that it is a major pillar of economic competitiveness. Smart mobility based on Intelligent Transport Systems (ITS) allows to improve and ensure the optimal use of existing infrastructure before embarking on heavy and irreversible infrastructure projects. The case regarding the separation of the urban traffic and the Heavy Goods Vehicles (HGV) traffic circulating between Casablanca Port and Zenata Dry Port is a relevant example where smart mobility could provide efficient solutions without building costly tunnels. A dynamic simulation was made using the Aimsun software to quantify the relevance of the proposed lane designated to HGV in the existing road. This simulation allows to visualise congestion sections and quantify the circulation of vehicles and pedestrians. The article presents defined functions and characteristics of the Advanced Traffic Management (ATM) to ensure the optimal operation and efficient setting of the simulation. All appliances, hardware, and sensors that will be set up on-site will help to improve traffic safety, traffic flow, traffic information, and reduce congestion and pollution. This case study illustrates the complexity of managing the flow of goods in cities and suggests how to solve this type of problems using smart mobility. This research proposes reserving a special lane for HGV. ITS will help this cost-optimal alternative, will promote the urban framework of the coastal road, and contribute to sustainable mobility in Casablanca.
