Introduction: Percutaneous ultrasound-guided core needle biopsy is a well-established method in the diagnosis of musculoskeletal tumors. It is unclear which factors contribute the most to a successful biopsy. The aim of the study was to determine the value of ultrasoundguided core needle biopsy of solid lesions in the musculoskeletal system using a 16-gauge needle. Material and methods: A retrospective analysis performed at a regional sarcoma center over one year included patients referred for ultrasound-guided biopsy of musculoskeletal soft tissue lesions. At least 6 months’ clinical and radiological follow-up, results from repeat or excisional biopsy, or interventional treatment, served as outcome reference. The biopsy procedure and yield were analyzed. The biopsy was classified as ‘diagnostic’ when a definitive diagnosis could be made on the first biopsy, and ‘accurate’ when only the malignant or benign nature of the tumor could be determined. Results: From 102 referrals for biopsy of soft tissue lesions in 2019, a total of 73 biopsies of solid lesions with a 16-gauge cutting needle were included (73 patients). There were 34 males and 39 females, with a mean age of 57.7 years. The overall proportion of diagnostic biopsies was 84%, for malignant lesions 88% and benign lesions 81%. The tumor could be classified as malignant or benign in 12 patients (16%) (accurate biopsy). It was possible to discriminate between malignant and benign lesions in each case. The majority of biopsied lesions were benign 64% (n = 47). Conclusion: The diagnostic value of ultrasound-guided percutaneous core needle biopsy of musculoskeletal soft tissue lesions performed with 16-gauge needle is good, with a high rate of diagnostic biopsies, both for benign and malignant lesions.

Aim of the study: The aim of this study was to evaluate the long-term effects of access to the femoral artery for the purposes of coronary angiography through the measurement of femoral artery distensibility and elasticity on the accessed and non-accessed sides. Material and methods: This cross-sectional study included patients who underwent femoral angiography at least 1 year previously. Those whose femoral artery was accessed once formed Group 1 (n = 59), those who were accessed twice formed Group 2 (n = 57), those accessed 3 times formed Group 3 (n = 55), and those with more than 3 accesses, Group 4 (n = 60). The groups were compared in respect of femoral artery elasticity and distensibility in the accessed and non-accessed sides. Results: No statistically significant difference was determined in respect of femoral distensibility and elasticity in Group 1 (9.40 ± 0.84 vs 9.48 ± 0.75, p = 0.107 and 0.23 ± 0.03 vs 0.23 ± 0.03, p = 0.433, respectively). However, a significant difference was observed between the two sides in terms of distensibility and elasticity in Group 2 (9.02 ± 0.81 vs 9.23 ± 0.75, and 0.21 ± 0.02 vs 0.22 ± 0.02), in Group 3 (8.49 ± 0.77 vs 9.18 ± 0.9 and 0.19 ± 0.02 vs 0.21 ± 0.02), and in Group 4 (8.14 ± 0.74 vs 9.03 ± 0.81 and 0.16 ± 0.01 vs 0.2 ± 0.02, p <0.001, for all comparisons). Conclusion: While a single access in the femoral artery for coronary angiography does not affect femoral artery elasticity and distensibility, multiple accesses may have adverse effects.

Point of Care Ultrasound is an increasingly popular modality in the emergency department as well as in the critical care unit. Its applications are varied, centered on its role in diagnosis, thereby minimizing the time taken for the appropriate diagnosis to be made and hence incorporate definitive treatment. There are currently no international guidelines published with regards for point of care ultrasound in the context of cardiac arrest. We propose to delineate the impact of the role of point of care ultrasound in a patient with cardiac arrest, in the evaluation of the cause, its prognostic role, as well as possible implications for therapies based on a case report.
Evaluation of Changes in the Mechanical Properties of O-Ring in One Piece and Two Piece Ball Retained Implant Supported Overdentures: A Three-Year Retrospective Study
Authors: Banu R. Fathima , Kumar V. Anand
Published: March 2021

The O-rings in ball retained overdentures deteriorate with time and need replacement to restore the retentive quality. We evaluated retrospectively the mechanical properties of O-rings after 3 years in function in 1 and 2-piece implant-supported overdentures. The O-rings were retrieved from one-piece (Myriad snap, Equinox-Straumann, 3.3 × 13 mm) and 2-piece (Neo Biotech, 3.3 × 13 mm) implant-supported overdenture patients. A total of 16 pairs of matrices were tested for wear, type of damage, and elasticity using Pin on Disc method, USB Digital Camera in 30× zoom and Universal Tensile Machine, respectively. The statistical analysis for independent groups were done with the Mann-Whitney U test. Assessment of used O-rings showed 84% more wear in the 2-piece system with an abrasive type of damage while 46% wear in the 1-piece system with a compressive type of damage. The O-rings in 1-piece system showed increase in elongation and maximum displacement to 2% and 7%, respectively, whereas the 2-piece system showed decrease in elongation and maximum displacement by 13% and 6%, respectively. In 1-piece system, the loss of retention was more with slow wear rate, and in 2-piece system, the wear resistance of O-rings decreased due to increased stiffness. Further studies to evaluate the changes in O-ring with increased sample size and at interval 1 year will pave way for insight into the progressive changes in the mechanical properties of an O-ring.

Authors: Aliyeva Nadezhda
Published: March 2021

Introduction: the paper discusses the procedure for familiarizing the accused with the materials of the criminal case. The paper identifies the main problems that arise in the practice of resolving petitions filed after the familiarization with the materials of the criminal case. In the paper, the author analyzes the procedure for familiarizing the accused and his defense lawyer with the materials of the criminal case, which is one of the important stages in the pre-trial proceedings. In the course of the study, it was found that the accused has more opportunities to exercise their right to submit petitions than other participants in the criminal proceedings. In the course of the research, the author investigated the theoretical and practical problems that arise when familiarizing the accused with the materials of the criminal case. In this paper, the author sets the goal of the study: to analyze the procedural order for familiarizing the accused with the materials of the criminal case. Methods: the methodological framework for the research is the general scientific system method, which examines the issues related to the activities of the investigator at the stage of familiarization of participants in the criminal proceedings with the materials of the criminal case. It is necessary to emphasize the use of some specific scientific methods in the research, such as the comparative legal and formal logical methods. Results: the need to introduce a separate rule in the Criminal Procedure Code of the Russian Federation related to the issue of the procedure for filing a petition by the accused and his defense lawyer. Conclusions: the study revealed that it is necessary to improve the process for filing petitions, the rules for their consideration by the investigator, and ensuring that the parties to criminal proceedings guarantee the protection of their rights and legitimate interests. In particular, it is necessary to make additions to Article 217 of the Criminal Procedure Code of the Russian Federation in the paragraph on the need to fix the reasons for the inability to get acquainted with the material evidence and their further specification in the investigator’s decision.

Authors: Appazov Denis , Tymchuk Yulia
Published: March 2021

Introduction: the paper analyzes the prospects for creating a regulatory framework for the digital platforms in Russia. The paper examines the existing approaches to the definition of “digital platform” in the legislation and legal doctrine, determines their role in the implementation of the state policy on building a digital economy, as well as the factors that led to their accelerated implementation in public administration. A critical analysis of the actions planned in the National plan that ensure the restoration of employment and income of the population, economic growth and long-term structural changes in the economy associated with digital platformization is carried out. The paper reveals the existing problems in the domestic law enforcement practice related to the functioning of the digital platforms in the context of legal uncertainty. The paper examines the foreign experience of the legislative regulation of digital platforms. Methods: in the study, the authors used both the general scientific methods (dialectical method of cognition, analysis, synthesis, formal logical method, prognostic method, etc.) and the specific scientific methods (formal legal method, method of legal interpretation, etc.). Results: the need to create a regulatory framework for the digital platforms in order to eliminate the identified problems of the law enforcement practice is justified. Conclusions: based on the results of the study and taking into account the analysis of the positive foreign experience, the authors’ definition of the concept of digital (online) platform is formulated, and the main directions for improving the domestic legislation regulating the activities of the digital platforms in Russia are determined.
The German History of Concepts and the History of Political and Legal Doctrines: Facets of Interaction
Authors: Korovin Kirill
Published: March 2021

the German history of concepts became popular after the translation into Russian of some articles from “The Historical Dictionary of Socio-Political Language in Germany”. This event is remarkable for legal science, since legal concepts are of particular importance for both the legislator and legal scientists when developing legal doctrine. The purpose of the paper is to apply a historical and conceptual approach to the study of state-legal phenomena in the history of political and legal doctrines. Methods: the methodological basis of this study is a systematic approach that allows to structure the constituent elements of the German history of concepts, as well as a structural and functional one, thanks to which the application of specific elements in practice was shown. Results: as a result of the analysis of the German experience of studying concepts, the author made conclusions that reflect the possibility of its use in law. First of all, the classification of concepts used in the dictionary is important. It allows you to structure and systematize the concepts used in the political and legal doctrines. The processes of transformation of concepts described methodologically by the Germans can be analyzed by analogy in Russian historical and legal science. The context of the emergence and evolution of the concepts reflects the fundamental changes in society and the state, so its description is necessary to explain the features of legal concepts. Conclusions: the adaptation of historical concepts with the help of modern legal language to the terminological apparatus of the theory of state and law is possible through the diachronic principle. The linguistic basis of the German dictionary is certainly interesting for lawyers from the point of view that the distinction between terms and concepts contributes to the improvement of legal techniques. Thus, the German history of concepts is largely interrelated with the history of political and legal doctrines, and further development of this issue is required.

Theorising the Image as Act: Reading the Social and Political in Images of the Rural Eastern Cape
Authors: Steele Candice
Published: March 2021

Certain anthropological narratives of South Africa's Eastern Cape province, such as Monica Hunter's 1936 Reaction to Conquest and Philip Mayer's 1963 Townsmen or Tribesmen, persist as potent referential 'bodies of knowledge'. By laying down the coordinates of Black rural and urban experience, such studies continue to animate concepts of tradition and modernity, effectively conjuring up notions of 'the border', both literally and metaphorically. Encountering Pauline Ingle's photographic collection amidst these circuits of knowledge and ways of seeing is to recognise that it is both unusual and exceptional. It is a collection of over 4000 images that are not only located in a rural area but also covers a sustained time period, corresponding to the period of formal apartheid. The concept of the rural is amplified in the collection, positioning it as a site of development, as the 'not yet modern', in which subjects are figured both in class hierarchies and in relation to Daniel Morolong's urban photographs in and around East London in the 1950s. Employing the theory of social acts enables a re-contemplation of the subject, and a reading of the social that suggests a set of possibilities and futures beyond what currently constitutes the rural and the urban; and upturns the disciplinary optics that condition the predominating ethnographies and historiographies of the Eastern Cape.
An Openness to Experiment: Ruy Duarte de Carvalho's Anthropological Field Photography in Rural Southern Angola and its Archival Reusages
Authors: Ponte Ines
Published: March 2021

This article explores the afterlives of the photographic production by Ruy Duarte de Carvalho (1941-2010), a Portuguese-born Angolan anthropologist who amidst the country's long-lasting civil war (1975-2002) engaged with the Ovakuvale trans-humant shepherds dwelling in the semi-arid region of southern Angola. Through the 1990s, Carvalho used analogue photographic cameras to document his field-work among the Ovakuvale, and afterwards engaged in various experiments with the medium for ethnographic purposes. Departing from the current assemblage of Carvalho's personal archive that remains after he passed away, I explore distinct photographic relations connected to public usages of his Ovakuvale images during his lifetime, to discuss the ways in which he articulated them through diverse expressive modes and ventures - such as watercolours, illustrated publications, temporary exhibitions and a theatre play. Offering the opportunity to surrender to a broad experimental practice that makes his overall Ovakuvale ethnography particularly revealing, I project through the current archival assemblage a comparative approach to the rationales guiding the presentation of his Ovakuvale field images, to discuss salient temporal relationships between his method to produce and later reuse these images in postcolonial times.
Of Sky, Water and Skin: Photographs from a Zanzibari Darkroom
Authors: Gupta Pamila
Published: March 2021

In this article, I propose to take up the concept and physical space of a photographic 'darkroom' located in Stone Town, Zanzibar, to explore a set of images from the Capital Art Studio (1930-present) collection produced by Ranchhod Oza (1907-93), and inherited by his son Rohit Oza (1950-). I employ a concept of darkness to read this visual archive differently and propose multiple 'other lives' for a set of images. First, by bringing this African photography collection to light, I am taking it out of the 'dark rooms' of history in one sense and exposing it for interpretation. Second, I focus my lens on the Oza physical darkroom located in the back of the studio on Kenyatta Road in Stone Town, where photographs of a range of Zanzibari persons were both developed and printed and that open up the darkroom as a place of photographic complexity and sensorium, and not just mechanical reproduction. Third, I develop darkness as a form of beauty in certain images of sky, water and skin from this archive that showcase Zanzibar's position as an Indian Ocean island and port city whilst under rule by the Omani Sultanate (1698-1964) and British Protectorate (1890-1963). Fourth, I conceptualise the Zanzibar Revolution of 1964 as a time of visual darkness, which temporarily restricted photographic practices operating in Stone Town under the new Afro-Shirazi political party. Throughout my analysis, I use a framing of 'darkness' to interrogate photography as an aesthetic practice deeply immersed in materialities and metaphors of dark and light, black and white, and as integral to Zanzibar's oceanic islandness.

Attempted Portraits: Photography, Obscurity, and the Articulation of the Past
Authors: Morton Christopher
Published: March 2021

The essay draws on two case studies from the photographic archive of British social anthropologist Edward Evan Evans-Pritchard (1902-73) on a fieldwork expedition to Kenya and South Sudan in 1936. The case studies reveal how connections can be made within an archive to articulate new narratives around often well-known photographs. The case studies explore the relationship between two different practices of looking: that involved in the act of photography, and that of looking at archival photographs as historical sources. Whilst the abundance of visual information in the archive reveals photography's endless potential for recodability, the essay argues that the photographic archive is also characterised by obscurity and limitation, and that the small dramas that are sometimes fleetingly glimpsed in the photographic hinterland will for the most part remain partial, unintelligible, and unarticulable by historians. Although there is a visual abundance in the photographic archive with which we might engage, what is shown to us is not abundantly clear. The essay argues that the important historical connections between the concepts of visibility and knowledge in a discipline such as anthropology often break down when the archive is recalcitrant, revealing its own limits as much as its bounty.
Atlas of an Empire: Photographic Narrations and the Visual Struggle for Mozambique
Authors: Assubuji Rui
Published: March 2021

This article engages with the historiography of the Portuguese empire with reference to Mozambique. It explores the impact of visual archives on existing debates and asks what difference photographs make to our interpretation and understanding of this colonial past. Deprived of their 'historical rights' by the requirements of the Berlin treaties that insisted on 'effective occupation', the Portuguese started to employ a complex of knowledge-producing activities in which photography was crucially involved. This article examines different photographic moments before and during the 'Pacification Campaign' that assured Portugal's authority over the Gaza Empire in southern Mozambique in the 1890s, by official, commercial and missionary photographers. It identifies controversies over the small number of portraits of the Gaza king Ngungunyane that took on distinctive and disputed 'other lives' after their initial production. The realisation of how one image might be disassembled to generate others becomes an exercise - in visual terms - of rethinking colonial violence. A critical engagement with the slippages and repositionings around photographs, and the errors or disputes in various captions, allows for a better understanding of the production of both silence and particular narratives in the archives and popular history. The demonstration of these other lives matters because it stimulates awareness of what is seen, what is made visible, and addresses the desire to look beyond the image to find others in a continuous interrogation of photographic excess.
Effects of Fennel and Cumin Extracts on Flax Seed Germination Parameters and Mitotic Activity in the Root Tip Cells
Authors: GEDİK Osman , USLU Ömer Süha
Published: March 2021

Abstract

This study was carried out to determine the effects of cumin and fennel seeds extracts, on the germination, seedling development and mitotic activity in root end meristem cells of flax seed. The experiment was established in laboratory according to randomized plot factorial experiment design with three replications in incubator having 23℃ temperature. At the end of 14 days of germination period some germination parameters were measured. According to the control, it was observed that fennel extract applications positively affected the germination and seedling development of flax seed except 100 g/l dose. While germination is seen at 100 g/l, seedling growth is completely prevented. It was observed that all cumin extract applications had a negative effect on the germination and seedling development of flax seed compared to the control. This negativity has shown more effect in increasing doses. While the germination rate is gradually decreasing in increasing doses, it is observed that the growth of seedlings is completely prevented except 12.5 and 25 g/lcumin extract. Increased doses at doses other than 100 g/lincreased the mitotic index in fennel extract application and decreased the dose increase in cumin extract application. The percentage of chromosomal abnormality decreased in parallel with the increase in doses other than 100 g/l in fennel, but percentage of chromosomal abnormality increase with increasing doses in cumin extract. During mitotic examinations; mitotic abnormalities such as failure to collect the metaphase plate, bridge in anaphase and telophase were observed and their pictures were recorded.

To demonstrate an interesting and rare case in the clinical practice of testicular feminization syndrome in a child, as an accidental finding when performing a planned surgical intervention. A mother with a child E., born in 2010 (at the time the child was 4 years old) was hospitalized with the mothers complaints about the presence of protrusions in both inguinal areas from birth, the mother denied cases of infringement. The child was examined on an outpatient basis and the next day a scheduled surgical intervention was prescribed hernia repair on both sides. At the opening of the hernial sac on the right, the contents were the testicle, 1.6 1.6 1.0 cm in size, with an appendage and vas deferens. Then an opening of the hernial sac was performed on the left, the contents of the hernial sac was also a testicle measuring 1.8 1.2 1.0 cm with an appendage and d. deference. Examination was performed: on an ultrasound of the pelvic organs the bladder is full, the effusion in the pelvis is up to 1215 mm high, the uterus and ovaries are not located at the time of the examination. In the abdominal cavity (in the iliac regions), ovarian testicles with mediastinum are located on both sides 19 11 mm on the right, 16 10 mm on the left. The clinical case that we have provided will be of interest to pediatric surgeons and geneticists in view of the unusual and complex clinical diagnosis of this condition. In the presence of a female phenotype, the child completely lacked the organs of the female reproductive system, this disease was detected only due to the presence of a concomitant pathology in the child, a bilateral inguinal hernia. The early diagnosis of STF is especially important given the risk of malignancy of the gonads in the post-pubertal period.

Published: March 2021

Duplication of the gastrointestinal tract is a relatively rare malformation. The incidence is approximately 1 in 10 000 live births with the small intestinal duplication in most cases. Malformations with a long duplication part are considered technically complex. A successfully treated clinical case of the subtotal small intestinal duplication in a child is presented in the article. The mid-median mini-laparotomy was performed and a subtotal 1 meter length small intestinal duplication was revealed (from the Treitzs ligament to the ileum in 50 cm from the ileocolic valve). The proximal part of the intestinal duplication and its mucous membrane of the distal part with the common wall were completely removed. Histological examination found ectopia of the gastric mucosa and pancreatic tissue. Surgical treatment of this malformation is aimed at the complete removal of the duplication part due to possible ectopia of the gastric mucosa or pancreatic tissue. If the resection of an entire part of the intestinal duplication is technically impossible, the mucous membrane can be removed.

Introduction. The biggest difficulties of pulmonary sequestration treatment appear when they are combined with other congenital malformations.
Materials and methods. This article describes a rare case of combination of infradiaphragmatic extralobar sequestration of the lung and duplication cyst of the gaster. The antenatal ultrasound investigation at 21 week of gestation visualized a retroperitoneal mass that had a cystic-solid structure and a vessel that departed directly from the aorta. CT-scan that was performed after the birth, confirmed an existence of infradiaphragmatic cystic mass that had a vessel that departed directly from the aorta. We couldnt exclude the neoplastic process because of structure and topography of mass. Tumor markers were without pathology. Surgical treatment was performed: laparotomy and removal of the cyst and extrapulmonary sequestration. The histological investigation confirmed a pulmonary sequestrum and duplication cyst of the gaster.
Conclusion. A nowadays method of visualization allows to find congenital malformation in earliest stages of gestation. The tradition surgical treatment and also minimal invasive surgical treatment are the main option of cure such congenital malformations. Also literature review of rare clinical forms of pulmonary sequestration presented in this article.

Published: March 2021

Introduction. Penile agenesis (aphallia) is an extremely rare congenital disorder. At present, about 100 cases of the anomaly have been described around the world. The incidence of this congenital anomaly is estimated to be one case per 2030 million births. One of the most commonly used reconstructive procedures today is the technique proposed by Roberto De Castro in 2007. In this article, we present a clinical case of aphallia in a boy who underwent phalloplasty.
Materials and methods. A newborn boy presented with aphallia, combined with abnormal development of both kidneys. At birth, the child had difficult urination through the fistula at the edge of the anus. The meatotomy and urethral dilation were performed on the fifth day of the infant`s life. On day 28 of the child`s life, surgical intervention was performed to remove the left non-functioning kidney and a right cutaneous ureterostomy because of the recurrence of febrile urinary tract infection. At 13 months, the tissue expander was installed above the pubic bone. At 16 months, the child underwent the De Castro phalloplasty technique while in the supine position.
Results. The child was examined 3, 6, and 12 months after the surgical treatment. Phalloplasty has had good outcomes as evaluated by parents and surgeons. At present, the boy is under the supervision of urologists, who plan to perform further surgical treatment of the urinary system.
Conclusion. Phalloplasty, in the case presented, had a good cosmetic result. In our opinion, it proved to be the correct initial stage of treatment for aphallia, an extremely rare genital malformation.

The article discusses current approaches to anesthesia in providing vascular access in children in Russia and the framework of the existing problem and global practice. Several features of the child's body, such as small size, increased flexibility of the punctured vessel, expressed psycho-emotional and the childs motor reaction to a potentially painful invasive procedure create significant additional difficulties in peripheral vein catheterization in children, especially at an early age, compared with adults. This fact until recently caused a high frequency of unsuccessful peripheral vein catheterizations in children and, as a result, a high percentage of punctures and central vein catheterizations, which in turn is associated with the risk of serious potentially life-threatening complications accompanying the puncture and catheterization of the latter. The article describes various, including non-pharmacological methods for inducing adequate sedation and analgesia during vein catheterization. The parents presence in the intensive care unit plays an essential role in non-pharmacological methods of child protection. It is a factor that reduces stress and psycho-emotional stress, both for the child and indirectly for the medical staff. Information from domestic and foreign sources on the use of various administration methods and various pharmacological drugs demonstrate the variety of approaches to solving this urgent problem. This article presents our research results showing the advantages of using a combination of methods and drugs that provide adequate anesthesia, expressed as an increase in successful peripheral vein catheterizations, the corresponding reduction in the unjustified number of central vein catheterizations, and the positive economic effect accompanying this dynamic.
Diagnosis and treatment of infants with severe hydronephrosis (literature review)
Authors: Sergeeva Svetlana V.
Published: March 2021

Introduction. An assessment of the effectiveness of antenatal diagnosis and postnatal management of infants and infants with grade IV hydronephrosis was performed based on the analysis of domestic and foreign literature.

Literature review. In the literature analysis, we used the databases СlinicalKey, Web of Science, Cyberleninka, PubMed, and Medline. The search was not limited by the publication date; instead, the searchs emphasis was placed on publications of the last 10 years.

Classification. Several classification systems have been developed to assess the severity of hydronephrosis in infants. However, none of them describes the degree of expansion of the PCS and the functional state of the renal parenchyma. This work shows the stages of embryogenesis of the obstruction of the pyelourethral segment.

Diagnosis. The issues of antenatal diagnostics and prognostically significant outcome criteria for an intrauterine malformation of the fetal urinary system are considered. The main diagnostic methods in the postnatal period are described.

Morphological changes. Variants of pathomorphological changes in the renal parenchyma, the pelvic wall, and ureter in prolonged obstruction conditions are described. The role and variability of the number of Cajal interstitial cells in the pelvic wall and ureter in hydronephrosis have been analyzed.

Treatment. Particular attention is paid to nephroprotective therapy and surgical treatment tactics of the defect. Questions regarding the timing and choice of treatment methods, the need and duration of preliminary urine diversion in infants and children with grade IV hydronephrosis remain open.

Conclusion. Analysis of the world literature shows that there is no single protocol for intrauterine diagnosis and postnatal management of children with grade IV hydronephrosis. The functional state of the parenchyma is possible only with a comprehensive examination to assess the degree of hydronephrosis. Improving antenatal and postnatal diagnostics, therapeutic and surgical treatment of children with severe hydronephrosis should be based on a doctors cooperation, a specialist in ultrasound diagnostics, a nephrologist, and a pediatric surgeon.
The Search of Diffusive Properties in Ambient Seismic Noise

Published: March 2021

Ambient seismic noise (ASN) is becoming of interest for geophysical exploration and engineering seismology, because it is possible to exploit its potential for imaging. Theory asserts that the Green’s function can be retrieved from correlations within a diffuse field. Surface waves are the most conspicuous part of Green’s function in layered media. Thus, the velocities of surface waves can be obtained from ASN if the wavefield is diffuse. There is widespread interest in the conditions of emergence and properties of diffuse fields. In the applications, useful approximations of the Green’s function can be obtained from cross correlations of recorded motions of ASN. An elastic field is diffuse if the background illumination is azimuthally uniform and equipartitioned. It happens with the coda waves in earthquakes and has been verified in carefully planned experiments. For one of these data sets, the 1999 Chilpancingo (Mexico) experiment, there are some records of earthquake pre-events that undoubtedly are composed of ASN, so that the processing for coda can be tested on them. We decompose the ASN energies and study their equilibration. The scheme is inspired by the original experiment and uses the ASN recorded in an L-shaped array that allows the computation of spatial derivatives. It requires care in establishing the appropriate ranges for measuring parameters. In this search for robust indicators of diffusivity, we are led to establish that under certain circumstances, the S and P energy equilibration is a process that anticipates the diffusion regime (not necessarily isotropy), which justifies the use of horizontal-to-vertical spectral ratio in the context of diffuse-field theory.
Propuesta de un procedimiento para analizar las fallas en el servicio de alojamiento hotelero
Authors: González Arias Mahé , Frías-Jiménez Roberto Argelio , Gómez-Figueroa Olga
Published: March 2021

Este artículo presenta una metodología que articula el análisis del modo y efecto de fallas en la prestación del servicio (SFMEA), con el estudio del despliegue de la calidad, conocido en inglés como Quality Function Deployment (QFD). Sin olvidar el enfoque de procesos que sustenta la relación entre el cliente y la empresa hotelera. Mediante la utilización de múltiples herramientas como Lluvia de Ideas, Método de Selección de Expertos, el Método Kendall, Diagrama de Árbol, así como estadísticos correlacionales, se permitió traducir los requerimientos de clientes en características de los procesos del servicio. Se evidencian, finalmente, las características técnicas que afectan el desempeño del servicio y cómo influye en la satisfacción del cliente. Se identifican fallas que tienen un impacto sobre el medio ambiente, que se relacionan con deficiencias en el consumo de agua y el uso de las fuentes de energía. El empleo de sustancias tóxicas para el aseo de las habitaciones genera contaminación local por el efecto de fuertes olores, con incidencia negativa en la sostenibilidad turística. Al identificar los momentos de verdad dentro del servicio, se establece un conjunto de acciones que favorecen un intercambio eficiente y satisfactorio para el cliente y la propia empresa hotelera.

Y continuando hemos finalizado con una alusión a los modos de resolución de conflictos relacionados con los derechos de las personas con discapacidad a través de  un análisis jurisprudencial a fin de conocer las soluciones judiciales ofrecidas en controversias derivadas de la accesibilidad en aquellas situaciones  en las que bien pudieran verse implicados los usuarios turísticos, así como también la solución extrajudicial de conflictos a través de la figura del arbitraje.
Financiación de proyectos relacionados con el sector turístico en la coyuntura actual: el papel de la colaboración público-privada como factor competitivo
Authors: Vasallo Rapela Alejandro Manuel
Published: March 2021

El turismo es clave para España y Portugal, y ha sido motor de desarrollo a lo largo de las últimas décadas. En la coyuntura actual, y en un contexto tan globalizado y competitivo, se requieren estrategias de innovación y  cambios profundos para mantener posiciones de liderazgo; de productos desde la oferta, de gestión y comercialización y sobre todo desde el análisis de proyectos de inversión/financiación, en los que las infraestructuras y la colaboración público-privada adquieren especial relevancia. La renovación desde la oferta, con la consecuente dotación de infraestructuras y servicios públicos, y las acciones públicas para fomentar un turismo sostenible de calidad, requieren nuevos enfoques en cuanto a la financiación de inversiones privadas y la intervención del sector público, en un entorno de restricciones de la financiación bancaria, y de disminución del Gasto Público de las Administraciones. En este trabajo se analizarán los retos relevantes de los nuevos proyectos dirigidos a mejorar la eficiencia y  sostenibilidad desde la financiación, con el consiguiente impacto en la competitividad, cuestión fundamental para compensar los efectos negativos que tienen en la cuenta de resultados factores como; caídas de la demanda, presión sobre los precios como consecuencia de los menores presupuestos que las economías domésticas destinan al ocio, e inflación de costes.
