Alteraciones en el neurodesarrollo de niños con microcefalia causado por el virus del Zika.
Authors: Aguilar Cañas Sandra Johanna , Pérez Maldonado Doryeis
Published: December 2021

el virus Zika es un flavivirus que se transmite por la picadura del mosquito Aedes aegypti, que también es el vector que transmite el virus Dengue y Chicungunya. Se identificó por primera vez en Uganda en 1947 y el primer caso en humanos fue diagnosticadoen 1952 en Tanzania. METODOS: se realizó una revisión sistemática Cochrane en el segundo semestre del año 2018, siguiendo el modelo PICO para la formulación de pregunta y estrategia de búsqueda. La propuesta del modelo PICO se utiliza en la atención médica basada en la evidencia y su ontología define los criterios de la terminología a utilizar. RESULTADOS: La asociación delvirus Zika con microcefalia y otras alteraciones neurológicas severas fue reportada principalmente en Brasil en el 2015. ANÁLISIS Y DISCUSIÓN: en el campo de la salud, la importancia del Zika radica en la relación que ostenta con otros virus del género flavivirus que producen enfermedades como el dengue, el Chicungunya, fiebre amarilla, la fiebre del Nilo occidental y la encefalitis japonesa. De allí, la especial atención que tiene el tema en todo el mundo, dado que las enfermedades pueden extenderse a todo el globo, y la infección por virus Zika no es la excepción. CONCLUSIONES: la evidencia científica demuestra la relación entre la infección por el virus Zika y las malformaciones congénitas del sistema nervioso central de recién nacidos, al confirmar la presencia del virus en muestras de tejido placentario y líquido amniótico.

Narración e intertextualidad en Volver (Pedro Almodóvar, 2006)
Authors: Poyato Sánchez Pedro
Published: December 2021

Cualquier película de ficción suministra, en su desarrollo, una serie de informaciones con las que el espectador va construyendo una historia coherente y comprensible. Pedro Almodóvar, cineasta especialmente interesado en la práctica de la narración, ensaya en Volver (2006) un modelo que, además de obligar al espectador a revisar continuamente las expectativas e hipótesis generadas, viene gobernado por pausas y retrasos en el suministro informativo que cobran la forma de intertextos, así sean musicales, televisivos y cinematográficos. El objetivo de este trabajo es el estudio de dicho modelo narrativo-intertextual propuesto por el filme.
Deeds and Words: The Holloway Jingles and the Fight for Female Suffrage
Authors: Bagüés Bautista Marta
Published: December 2021

This article explores the importance of the written word of the Holloway Jingles in the fight for female suffrage through the analysis of the Foreword, “There’s a Strange Sort of College” and “L’Envoi.” Firstly, it will focus on the importance of writing as a venting tool for the suffragettes and it will demonstrate the idealization of imprisonment in the collection by comparing it to realistic and autobiographical accounts of life in Holloway Gaol, as well as the relevance of such an idealization in order to strengthen the bonds between the suffragettes both inside and outside of prison. Secondly, it will explore the impact of the collection within the feminist movement relating it to Virginia Woolf’s and Mary Wollstonecraft’s ideas, thus focusing on a wider notion of justice and freedom that was essential for their emancipatory fight.
Spectral Streams of Post-Consciousness in Mike McCormack’s Solar Bones (2016)
Authors: Altuna-García de Salazar Asier
Published: December 2021

This article analyses Mike McCormack’s novel Solar Bones (2016) which narrates in a run-on sentence Marcus Conway’s everyday life within the rural context of a 2008 Celtic Tiger Ireland about to collapse. Drawing upon the narratological precepts of experimental writing, especially the use of streams of consciousness, and Derrida’s hauntology, this article argues that McCormack’s novel charts tensions of coherence and collapse in post-Celtic Tiger fiction. The narration takes place within a post- perspective as Marcus’s ghost brings it into existence. The experimentation with streams of post-consciousness and spectrality provides McCormack with valid aesthetic mechanisms to respond in fiction to Celtic Tiger concerns.
Análisis iconográfico de la epigrafía funeraria romana de la provincia de Cáceres
Authors: Centeno Díaz Jose Luis
Published: December 2021

El principal propósito de este escrito es la recopilación y el análisis de las imágenes recogidas en la epigrafía funeraria de Cáceres en época altoimperial, temática hasta el momento poco tratada por la investigación. Si bien la iconografía y su examen son los ejes centrales de nuestro artículo, consideramos también fundamental su conjugación con el estudio del soporte, del material y de la onomástica, puntos capitales para una comprensión completa del epígrafe. La consideración de las imágenes, no ya solo desde una perspectiva ornamental o religiosa, sino como expresión del individuo y de la comunidad, podría permitirnos entrever la creación y la evolución de la sociedad hispanorromana en esta área de la Lusitania.
Algo más que la puerta del Hades Los arcos de herradura en las estelas del noroeste.
Authors: Sánchez Jaén Jesús
Published: December 2021

Una estela romana procedente de Petavonium (Zamora) con tres arcos de herradura bajo la cartela sugiere la existencia de un modelo arquitectónico funerario en el que el arco de herradura tenía un papel tanto constructivo como simbólico. El objetivo es demostrar que este arco se usó en la meseta norte con carácter funerario al menos desde finales del siglo I, sin necesidad de influencias orientales. La similitud de los arcos de las estelas con los de algunos mausoleos coetáneos nos lleva a concluir que las estelas contenían una representación simbólica de los mausoleos.
El nuncio Federico Borromeo y la caída del padre Nithard (1668–69)
Authors: Ribot García Luis
Published: December 2021

El artículo estudia la intervención del nuncio de Clemente IX, Federico Borromeo, como mediador en la crisis política que supuso la salida de la corte y de España del jesuita Everardo Nithard, confesor y favorito de la reina Mariana de Austria, al final del primer periodo de la regencia de Carlos II, en los años 1668 y 1669. La correspondencia de Borromeo que se conserva en el Archivio Apostolico Vaticano y la cada vez más amplia bibliografía existente llevan al autor a revisar el análisis de aquellos acontecimientos en los que, junto a la oposición de importantes sectores cortesanos, tuvo un importante protagonismo don Juan de Austria, hermano bastardo de Carlos II.
Castilla a finales del Antiguo Régimen en diversos textos de época
Authors: García Fernández Máximo
Published: December 2021

A finales del Antiguo Régimen se multiplicaron los textos relacionados tanto con el desarrollo del mérito personal a través del estudio y un sistema educativo renovado como con la crítica a las innovaciones indumentarias que únicamente potenciaban las pompas y lujos de las modas (pecados de vanidad que solo atendían a la notoriedad de un poder efímero). La reflexión sobre los mismos permite valorar mejor las inercias y transformaciones culturales castellanas.
Lipsio en Roma. Clemente VIII, Felipe III y el despliegue del tacitismo en la diplomacia española
Authors: Cabeza Rodriguez Antonio
Published: December 2021

La corte romana, teatro de la política europea, sirve de laboratorio para examinar la razón de Estado practicada por los países católicos en tiempos de la Contrarreforma. Se trata de demostrar el despliegue del tacitismo en la diplomacia española en Italia, que Felipe III aprobó para asegurar la quietud y neutralizar las novedades contrarias a los intereses de la Monarquía. La historiografía que ha estudiado el pontificado de Clemente VIII no llega a plantearse el tipo de prudencia que rigió en su gobierno temporal, de ahí que haya habido que definirlo. Buena parte del discurso se apoya en el Politicorum sive Civilis Doctrinae libri sex de J. Lipsio. A partir de información de archivo se da explicación a la demora observada en la edición española (desde que fue oficialmente aprobada hasta su publicación), y la coincidencia con la edición italiana publicada en Roma el año 1604, que se analiza junto a copias autorizadas y manipuladas.
Lenguaje político y lenguaje turístico: un análisis contrastivo español-italiano
Authors: Francesconi Armando
Published: December 2021

En este artículo se destaca el papel de la lingüística contrastiva, tanto en la didáctica como en la traducción, a la hora de comparar dos lenguas que siempre se han considerado similares, aunque se trate de una engañosa semejanza. Más concretamente, en este trabajo se aplicará el análisis contrastivo para identificar correctamente los problemas de equivalencia que haya entre los lenguajes políticos y turísticos españoles e italianos. Antes que nada, en la introducción, se tratará de averiguar qué se define por el sintagma “lengua de especialidad” para evaluar si se pueden incluir en tal denominación los dos lenguajes objeto de estudio. Analogamente, se identifica un corpus de estudio y luego se menciona el método que se va a emplear: un análisis contrastivo detenido para medir las simetrías y disimetrías entre los dos códigos. En la segunda epígrafe, se profundizan las características tanto del lenguaje político como del lenguaje turístico y en la tercera, punto central del trabajo, se aborda un estudio cruzado de los dos lenguajes y sobre todo de los llamados “afines ilusorios”, las palabras culture-bound, alteradas y “comodín” y al mismo tiempo se aclara la naturaleza de las combinaciones libre o no de palabras.

Authors: Espinilla Herrarte María Lourdes
Published: December 2021

En la actualidad, con la abundancia de medios publicitarios y las modalidades de publicidad agresiva y sobredimensionada, nos podría parecer que el procedimiento publicitario y su intensidad, a comienzos del siglo XX y en una provincia como Palencia, podría ser pobre y deficiente. Sin embargo, también se aprovechaban los recursos disponibles y a través de ellos se pretendía difundir el mensaje a nivel social más amplio. Así lo vemos en el primer tercio del siglo XX en Palencia. En este caso nos referimos al campo de la educación.

Socio-Environmental Vulnerability of Water in the Estuary of the Metropolitan Region of Santos (Brazil)
Authors: Martins Fernando L.C. , Giordano Fabio , Barrella Walter
Published: December 2021

Santos and São Vicente Estuarine Complex (SSEC) is a densely populated coastal area that houses the main port in Latin America and the most prominent Brazilian industrial complex. Irregular occupations in preservation areas result in a disorderly increase in population, with negative social and environmental impacts. We evaluated the average annual growth of 74 slums occurring in this area and variations in water quality from 2005 to 2018. We monitor the growth of the occupied areas and estimate their respective populations. The average annual population growth was over 6% per year (p.a.). Invasions of new areas and verticalisation of already occupied areas represent 85% of the growth seen. The monthly polluting loads exceeded 450 tonnes or 2,086,000 m3, compromising the waters and local and regional public health. We strongly recommend re-urbanising the area using the resource savings caused by water loss to reduce the risks of ecosystem degradation, damage to health and disease spread.
Systemic lupus erythematosus and immunodeficiency
Authors: Chan Shirley Chiu Wai , Lau Chak Sing
Published: December 2021

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease caused by a combination of genetic, epigenetic, and environmental factors. Recent advances in genetic analysis coupled with better understanding of different immune regulatory and signaling pathways have revealed the complex relationship between autoimmunity, including SLE, and immunodeficiency. Furthermore, the expanding therapeutic armamentarium has led to the increasing awareness of secondary immunodeficiency in these patients. This article serves to update the current understanding of SLE and immunodeficiency by discussing the shared genetic factors and immunobiology. We also summarize the effects of immunosuppressive therapies with a focus on secondary antibody deficiency (SAD) after B-cell targeted therapies.
CD8+ T regulatory cells in lupus
Authors: Singh Ram P. , Bischoff David S. , Hahn Bevra H.
Published: December 2021

T regulatory cells (Tregs) have a key role in the maintenance of immune homeostasis and the regulation of immune tolerance by preventing the inflammation and suppressing the autoimmune responses. Numerical and functional deficits of these cells have been reported in systemic lupus erythematosus (SLE) patients and mouse models of SLE, where their imbalance and dysregulated activities have been reported to significantly influence the disease pathogenesis, progression and outcomes. Most studies in SLE have focused on CD4+ Tregs and it has become clear that a critical role in the control of immune tolerance after the breakdown of self-tolerance is provided by CD8+ Tregs. Here we review the role, cellular and molecular phenotypes, and mechanisms of action of CD8+ Tregs in SLE, including ways to induce these cells for immunotherapeutic modulation in SLE.
Nanoparticle-mediated delivery of IL-2 to T follicular helper cells protects BDF1 mice from lupus-like disease
Authors: Ferretti Concetta , Horwitz David A. , Bickerton Sean , La Cava Antonio
Published: December 2021

We recently reported that poly lactic-co-glycolic acid (PLGA) nanoparticles (NPs) loaded with interleukin (IL)-2 and targeted to T cells inhibited the development of lupus-like disease in BDF1 mice by inducing functional T regulatory cells (Tregs). Here we show that the protection from disease and the extended survival of BDF1 mice provided by IL-2-loaded NPs targeted to T cells is not only due to an induction of Tregs but also contributed by an inhibition of T follicular helper (TFH) cells. These results identify a dual protective activity of IL-2 in the control of lupus autoimmunity, namely the inhibition of effector TFH cells, in addition to the previously known induction of Tregs. This newly recognized activity of IL-2 delivered by NPs can help better explain the beneficial effects of low-dose IL-2 immunotherapy in systemic lupus erythematosus (SLE), and might be considered as a new strategy to slow disease progression and improve outcomes in lupus patients.

Published: December 2021

Physical exercise promotes the energy metabolism of the body. While physiological changes occuring in human body after regular exercise is well defined, it is not known how the body’s response changes during the time course of the exercise. Here, we investigated how the acute and chronic exercise alters expressions of genes related to energy metabolism and endurance. Our study investigated the effects of acute and chronic exercise on the expression of genes related to energy metabolism (AMPD1, PPARA) and endurance (ADRB2). Study group; was formed with 24 people: 12 healthy females and 12 healthy males. Maximal oxygen use capacities of the participants were determined by the Bruce test protocol at the beginning and end of the 8-week training program. After calculating their maximal oxygen use capacity, each participant was given an acute running exercise on the tread mill at the speed and incline that the participant would reach to his/her maxVO2 until he/she exhausted. The same people were built to continuous runs (%50-70) once every 8 weeks, and two days of medium-term interval training program (%90-95). Peripheral blood samples were taken before and after acute exercise and immediately after chronic exercises. RNA isolation was performed using TRIzol Reagent from peripheral blood mononuclear cells. Gene expression was determined by Biomark Real-Time PCR (RT-PCR). Gene expression data was quantified by using both t-test and Mann-Whitney U tests. The statistical level of p <0.05 was taken. Our results show that ADRB2 and AMPD1 gene expression values increase in women after acute exercise. There were changes in the mean values of ADRB2, AMPD1, PPARA gene expressions in both men and women after the 8-week training program compared to pre-acute exercise. Expression of PPARA gene significantly decreased after exercise compared to pre-exercise only for the female group. This study is important in developing ideas about gene expressions of genes related to energy training and endurance with different selections and different exercise programs. Our results; this suggests that different training programs on different genders are important in terms of giving an idea about the gene expressions of genes related to energy metabolism and endurance.

Published: December 2021

Fisioterapi adalah pengobatan terhadap penderita yang mengalami kelumpuhan atau gangguan otot dengan tujuan melatih otot tubuh agar dapat berfungsi secara normal. Fisioterapis merupakan salah satu bentuk pendukung pengobatan medis yang diberikan oleh berbagai klinik, yang salah satunya tersedia di Klinik Fisioterapi daerah Jakarta Barat. Klinik Fisioterapi ini masih mengandalkan sistem pendaftaran melalui telepon untuk proses administrasi pendaftaran pasien, sehingga pasien yang akan terapi harus menghubungi admin klinik minimal 1 hari sebelum melakukan terapi. Sesudah itu, secara manual, penerima telepon mengecek jadwal terapis yang tersedia. Untuk mengatasi permasalahan ini, pemanfaatan teknologi informasi dan komunikasi bisa menjadi solusi. Penggunaan perangkat telepon pintar berbasis Android saat ini terus mengalami peningkatan. Pasien dapat menggunakan sistem berbasis Android untuk mendaftar pada jadwal terapi yang tersedia menggunakan perangkat telepon pintar tanpa harus menelpon terlebih dahulu ke klinik. Untuk mempermudah proses administrasi saat kedatangan pasien, sistem pemesanan terapi juga dilengkapi QR Code pada sistemnya yang dapat digunakan untuk daftar ulang. Metode Organization Goal-Oriented Requriments Engineering (OGORE) digunakan untuk mengelisitasi kebutuhan dan spesifikasi sistem agar sistem yang dibangun lebih dapat memenuhi kebutuhan organisasi dibandingkan kebutuhan pengguna yang sudah terbiasa dengan cara manual selama ini berjalan. Dengan menggunakan metode OGORE pada penelitian ini diharapkan dapat mencapai tujuan sistem pendaftaran klinik fisioterapi dalam mempercepat proses pendaftaran pasien dan meningkatkan kualitas pelayanan bagi pasien yang akan melakukan Fisioterapi.

Published: December 2021

Deteksi penggunaan masker pada pengemudi kendaraan termasuk tugas klasifikasi yang dapat diselesaikan secara otomatis oleh kecerdasaan artifisial. Untuk implementasi pada perangkat mobile, arsitektur neural network MobileNetV2 dipilih dengan pertimbangan akurasi yang baik. Penambahan teknik data augmentation dan pemilihan optimizer ADAM semakin meningkatkan akurasi klasifikasi dari MobileNetV2. Proses deteksi dilakukan pada 13 foto pengemudi dengan masker dan 13 pengemudi tanpa masker. Untuk pengemudi tanpa masker, sistem pendeteksi berhasil 100%, meskipun ada salah satu kondisi saat pengemudi memakai masker di dagu, tingkat akurasi hanya sebesar 65,59%. Sedangkan untuk pengemudi tanpa masker, ada 1 foto yang salah, disebabkan oleh warna gelap yang digunakan sebagai masker, sehingga sistem pendeteksi mengklasifikasikan sebagai pengemudi tanpa masker dengan tingkat akurasi hingga 97,76%. Hasil analisis lebih dalam menunjukkan bahwa aksesoris seperti jilbab dan kacamata mempengaruhi tingkat akurasi yang dihasilkan oleh sistem pendeteksi. Sementara itu, tingkat akurasi juga lebih dipengaruhi oleh warna dari masker yang dipakai ketimbang pemilihan masker medis ataupun masker kain.

Perkembangan teknologi yang pesat membuat kita lebih mudah dalam menemukan informasi-informasi yang dibutuhkan. Permasalahan muncul ketika informasi tersebut sangat banyak. Semakin banyak informasi dalam sebuah modul maka akan semakin panjang isi teks dalam modul tersebut. Hal tersebut akan memakan waktu yang cukup lama untuk memahami inti informasi dari modul tersebut. Salah satu solusi untuk mendapatkan inti informasi dari keseluruhan modul dengan cepat dan menghemat waktu adalah dengan membaca ringkasannya. Cara cepat untuk mendapatkan ringkasan sebuah dokumen adalah dengan cara peringkasan teks otomatis. Peringkasan teks otomatis (Automatic Text Summarization) merupakan teks yang dihasilkan dari satu atau lebih dokumen, yang mana hasil teks tersebut memberikan informasi penting dari sumber dokumen asli, serta secara otomatis hasil teks tersebut tidak lebih panjang dari setengah sumber dokumen aslinya. Penelitian ini bertujuan untuk menghasilkan peringkasan teks otomatis pada modul pembelajaran berbahasa Indonesia dan mengetahui hasil akurasi peringkasan teks otomatis yang menerapkan metode Cross Latent Semantic Analysis (CLSA). Jumlah data yang digunakan pada penelitian ini sebanyak 10 file modul pembelajaran yang berasal dari modul para dosen Universitas Mercu Buana, dengan format .docx sebanyak 5 file dan format .pdf sebanyak 5 file. Penelitian ini menerapkan metode Term Frequency-Inverse Document Frequency (TF-IDF) untuk pembobotan kata dan metode Cross Latent Semantic Analysis (CLSA) untuk peringkasan teks. Pengujian akurasi pada peringkasan modul pembelajaran dilakukan dengan cara membandingkan hasil ringkasan manual oleh manusia dan hasil ringkasan sistem. Yang mana pengujian ini menghasilkan rata-rata nilai f-measure, precision, dan recall tertinggi pada compression rate 20% dengan nilai berturut-turut 0.3853, 0.432, dan 0.3715.

The luminescence and electroluminescence of an ethyne-linked zinc(II) porphyrin pentamer have been investigated, by testing blends in two different conjugated polymer matrices, at a range of concentrations. The best results were obtained for blends with the conjugated polymer PIDT-2TPD, at a porphyrin loading of 1 wt%. This host matrix was selected because the excellent overlap between its emission spectrum and the absorption spectrum of the porphyrin oligomer leads to efficient energy transfer. Thin films of this blend exhibit intense fluorescence in the near-infrared (NIR), with a peak emission wavelength of 886 nm and a photoluminescent quantum yield (PLQY) of 27% in the solid state. Light-emitting diodes (LEDs) fabricated with this blend as the emissive layer achieve average external quantum efficiencies (EQE) of 2.0% with peak emission at 830 nm and a turn-on voltage of 1.6 V. This performance is remarkable for a singlet NIR-emitter; 93% of the photons are emitted in the NIR (λ > 700 nm), indicating that conjugated porphyrin oligomers are promising emitters for non-toxic NIR OLEDs.

Objectives.

To identify barriers and enablers to accessing school-based eye health programs in Bogotá, Colombia.

Methods.

We undertook a qualitative case study that explored how structural factors, and social and cultural norms influence access to school-based eye health programs. We conducted focus groups discussions and interviews with a purposive sample of 37 participants: government stakeholders (n = 4), representatives from nongovernmental organizations (n = 3), and an eye-care practitioner, as well as teachers (n = 7), a school nurse, parents (n = 7), and children (n = 14) from private and public schools. Data were analyzed using a priori themes from the availability, accessibility, acceptability and quality framework.

Results.

Routine vision screening in schools is not currently provided nor is there a budget to support it. Lack of collaboration between the health and education ministries and the absence of national planning affected the delivery of eye care in schools. Factors related to acceptability of school-based eye health programs included: poor acceptance of training teachers as vision screeners; stigma related to wearing spectacles; and distrust of health services. The cost of spectacles and poor access to eye health information were identified as barriers to positive child eye health outcomes by socioeconomically disadvantaged parents and children.

Conclusion.

Our findings suggest the need for a national school eye health plan and improved cooperation between health and education ministries. Interventions to improve trust in health services, tackle the lack of human resources while respecting professional qualifications, and raise awareness of the importance of eye health are recommended.
Optimal deployment of the spoke of a largesized transformable reflector according to the hierarchy of criteria

Published: December 2021

The article discusses the process of controlling the angular motion of the spoke of a large-sized space-based reflector, taking into account bending vibrations. Currently, large antennas are actively used for receiving and transmitting data. When launching large structures into space, the problem arises of reliably deployment the spokes, since they are packed in a small volume to be able to be installed in a launch vehicle. Due to the possibility of various abnormal situations, such as jamming of elements, engagement of the net, it is necessary to re-deployment the antenna. Therefore, it is important to develop control algorithms that can reliably solve the problems of direct and reverse motion. In the process of deployment and bringing together the elements of the reflector, various deformations appear in the structure. When the antenna spokes are brought together, lateral oscillations make the largest contribution to the oscillatory of the transient process. Currently, elastically deformed elements are used to deployment large-sized reflectors, and a control program is also used. This prevents the control from being adjusted when the deployment conditions change. The paper investigates the possibility of minimizing the vibrations of a structure during its deployment by using optimal control algorithms in real time. The forward and reverse motion of the antenna elements is performed by means of a two-criteria hierarchy optimization. The results of numerical simulation of the optimal rotation of the reflector spoke are presented. The proposed algorithm allows you to choose the optimal control in emergency situations for various types of large reflectors.

The work is devoted to the protection of a spacecraft from the influence of unacceptable internal vibration sources. The urgency of reducing the vibration activity on board the spacecraft to improve the accuracy of the target equipment is indicated. A particular problem of vibration protection of the spacecraft platform from a vibration source – an electric pump unit of a liquid thermal control system – is being solved. The basic requirements for electric pump unit vibration protection have been determined. Possible ways to reduce the level of vibration excited by the electric pump unit on the surface of the spacecraft fixation are considered. Particular attention is paid to such vibration protection methods as damping and vibration isolation, implemented by installing special vibration protection devices between the source (electric pump unit) and the object (spacecraft) – vibration isolators and vibration dampers. The principles of operation of vibration dampers and vibration isolators, the most common materials for vibration dampers are described. Examples of constructive solutions for linear single-axial vibration isolators are considered, recommendations for the use of promising products are developed. Particularemphasis is placed on the use of metal rubber as a material for vibration isolators. With regard to a specific design of electric pump unit, a diagram of the spatial structure of vibration isolation is proposed. Formulas for calculation are given in detail, a mathematical model of the vibration isolation system is developed. The procedure for calculating the parameters of the system has been formed. Based on the model, the maximum possible level of vibration suppression in the mid-frequency region was determined. Minimum required number of operable pixels was identified for monitoring the water surface with sufficient accuracy and reliability.
