Presencia de Samuel Johnson en el «Diccionario castellano» (1786-88) de Esteban de Terreros
Authors: Carriscondo-Esquivel Francisco-M. , Carpi Elena
Published: June 2021

El Diccionario castellano con las voces de ciencias y artes (DC 1786-1788) del jesuita español Esteban de Terreros y Pando fue continuado por Los tres alfabetos francés, latino e italiano con las voces de ciencias y artes que les corresponden en la lengua castellana (1793). Mantenemos la hipótesis en este trabajo de que tanto el prólogo que figura en el DC (1786-1788) como las “Memorias” (1793) que redactó Miguel de Manuel y Rodríguez para su continuación parecen haber bebido de una fuente común: el prefacio que el lexicógrafo inglés Samuel Johnson puso al frente de su A Dictionary of the English Language (DEL 1755). Parecen confirmar esta idea varios indicios que tienen que ver con aspectos externos e internos. Metodológicamente, hemos procedido al cotejo de los textos implicados y a la búsqueda de información sobre cómo Terreros pudo conocer la obra de Johnson y cómo la manejó para la elaboración de su diccionario. Así podremos llegar a confirmar lo que, a nuestro juicio, supone un episodio relevante, de gran calado, para la historia de la lexicografía hispánica.
Planificación lingüística y desarrollo de lenguas minoritarias
Authors: Escoriza-Morera Luis
Published: June 2021

La evolución del mapa lingüístico mundial refleja la progresiva disminución de lenguas habladas en el planeta y la desaparición de sistemas lingüísticos en situaciones de contacto. El análisis de las causas de dicha desaparición permite también calificar a un importante número de modalidades como lenguas en peligro de extinción, para las cuales el apoyo oficial resulta indispensable para preservar su existencia. El estudio de diferentes textos legales, de naturaleza general o particular, en el marco de los denominados derechos lingüísticos, nos permitirá descubrir los contextos de uso concretos en los que dichas lenguas pueden ser defendidas institucionalmente y, al mismo tiempo, identificar diferentes actuaciones que oscilan entre la mera preservación, a veces casi exclusivamente documental, de lenguas minoritarias, y el desarrollo de medidas que pretenden realmente garantizar el uso de lenguas en ámbitos públicos como la educación, los medios de comunicación y la administración, de los que habían estado ausentes en periodos anteriores.

Introduction. Grave’s disease (GD) can be treated using three modalities: anti-thyroid medications, radioactive iodine therapy (RAI), or surgery. If surgery is selected, total thyroidectomy is the procedure of choice. Patients with hyperthyroidism frequently have an enlarged thyroid gland, occasionally with a pyramidal lobe. Aim. We point the usefulness of thyroid scintigraphy, which provides valuable information regarding the thyroid anatomy. Description of the case. The manuscript presents a case report of 43-year-old woman with unstable Grave’s disease, who underwent thyroidectomy and developed persistent hyperthyroidism postoperatively. She was referred by an endocrinologist to a nuclear medicine outpatient clinic for RAI therapy. I-iodide scintigraphy revealed two foci with excessive tracer accumulation. One of the foci in the middle of the neck corresponded to the pyramidal lobe. Conclusion. The thyroid anatomy anomalies can lead to unnecessary implications for treatment. Identifying the pyramidal lobe preoperatively and removing it from patients requiring total thyroidectomy may decrease the recurrence rate of hyperthyroidism. Thyroid scintigraphy is a useful diagnostic tool to visualize the pyramidal lobe.

Introduction. Although most organizations recommend breastfeeding for at least one year due to its well-known beneficial effects, the prevalence of exclusive breastfeeding in many developing countries was quite low. Aim. To identify prevalence and predictive factors affecting exclusive breastfeeding in Primary Healthcare (PHC) Centers in Cairo, Egypt. Material and methods. A cross-sectional study, among mothers attended first six months immunization sessions in three PHC Centers were selected via a convenient sample, A total sample of 180 mothers, 60 from each PHC Center, were subjected to an interview questionnaire. The questionnaire used was previously validated and pre-tested. Data collection took the period from April to August 2019. Comparison between exclusive and nonexclusive breastfeeding according to possible risk factors was done. Results. The frequency of breastfeeding among the participants was 90.6%; however the total exclusive breastfeeding frequency was only 39.4%. Our logistic regression model showed that exclusive breastfeeding decreased with progressive increase in infant’s age (OR 0.74), and mothers with good knowledge about proper practice of breastfeeding adhered more to exclusive breastfeeding (OR 2.51). Also, it showed that, during working hours, mothers who fed their infants other than breast milk adhered less to exclusive breastfeeding (OR 0.19). Conclusion. The prevalence of exclusive breastfeeding is quite low. The predictive factors for exclusive breastfeeding are, younger infant’s age, good knowledge of the mothers about proper practice of breastfeeding, and mothers insisting on breastfeeding during working hours.
TMEM106C is overexpressed and modulates cell mobility in metastatic colon cancer cells
Authors: DÜKEL Muzaffer
Published: June 2021

Colon cancer is the third most commonly diagnosed cancer in men worldwide. Colon cancer grows slowly and metastasis has already occurred after diagnosis. Therefore, new targets are needed in the colon cancer treatment and diagnosis. Transmembrane proteins (TMEM) play a critical role and presents different expression profile in variety of tumor cells. TMEM106C is a TMEM family protein, but its role on colon cancer development is unknown. In this study, we aimed to investigate TMEM106C gene in metastatic colon cancer cells. TMEM106C gene expression level was tested by western blot, qRT-PCR and immunofluorescence methods. In order to test the effect of TMEM106C in colon cancer cells, this gene has been knockdown with shRNA technology. In addition, cell invasion, migration and adhesion assays were performed to clarify whether TMEM106C knockdown has effect on colon cancer metastatic characters. Ford the first time, in this study, we showed TMEM106C is overexpressed in colon carcinoma cells. Moreover, we demonstrated that cell migration, invasion and adhesion capabilities are reduced in TMEM106C silenced cells. Furthermore, we observed that metastatic cell morphology was changed upon to TMEM106C knockdown. In conclusion, we showed that TMEM106C gene is important for colon carcinoma cells.
A Handwritten Greek Hagiography of Russian Saints from Mount Athos: The Life of St Mitrofan of Voronezh
Authors: Bibikov Mikhail
Published: June 2021

Modern methods for studying old Russian texts are based on the reconstruction of foreign translations: this makes it possible to define the extent to which the world of the Middle Ages and the early modern period was acquainted with them. Post-Byzantine translations of the hagiographic works of old Rus’ and later periods are rare cases of such texts. The archive of the Athos Russian Monastery of St Panteleimon contains a text which makes up part of the Greek manuscript Cod. Athos. Panteleemon. gr. 283 (1848): it speaks of the life of St Mitrofan of Voronezh (†1703), a famous associate of Peter the Great canonised by the Russian Church in 1832. At the time of his canonisation, a handwritten abridged hagiography was released: this was followed a few years later by a longer version which the Greek text relies on. A codicological investigation has helped to identify the codex’s author and scribe: the monk Jacobos Neaksytiotes (1790s–1869), an outstanding theologian and historian (his opus magnum was Athonias) of Athos. The reconstruction of his biography and legacy allows the author of this article to understand this monk’s interest in Russian history and his translations of some hagiographic works from Russian into Greek. The article also contains a Russian translation of the Greek hagiographic text.
The Intellectual Adventures of a Russian Anti-Federalist: Radishchev, Condorcet, and the American Constitution
Authors: Zorin Andrey
Published: June 2021

This article suggests a new understanding of a shift in Radishchev’s perception of American democracy from the early version of Ode to Liberty to the final text of A Journey from St Petersburg to Moscow. The historical and political theories present in Ode to Liberty are interpreted not as an abstract social utopia but as a reaction to the revolution in British colonies and an attempt at establishing a new society based on the ideals of equality and freedom. The adoption of the American constitution was the main reason for Radishchev’s disappointment in the USA. The evolution of Radishchev’s views is analysed within the context of the American debate between the Federalists and the Antifederalists and the discussions about the New World in France, especially the political philosophy of Nicola Condorcet and the debates on the representation of the slave-owning colony of Santo Domingo in the Assemblée nationale. The article studies the key sources of information that may have influenced Radishchev’s opinion and analyses the common features of Radishchev’s ideas about the US Constitution and his critical approach to the “abolitionist” wing of the Antifederalists. His disappointment in the American experience had a decisive impact on Radishchev’s political philosophy: the adoption of a federalist constitution and the preservation of slavery meant for him the collapse of all hopes for reshaping society on more humane and just grounds. This led to the adoption of apocalyptic tones in the final version of Ode to Liberty, as the author’s hopes for a better future now depended not upon any political activity, but upon the intervention of providential forces.
Artworks of Russian Stone Carvers in the Diplomatic Service
Authors: Vinokurov Sergey
Published: June 2021

This review examines recently published works by Russian scholars in the field of artistic stone carving, namely, the reference book by N. M. Mavrodina, Works of Russian Stone-Carving Art in Collections outside Russia (2019), and the monograph by L. A. Budrina, Malachite Diplomacy (2020). Both works study objects created by Russian stone carving artists through the 18th – early twentieth century and which left the country as a result of various diplomatic occasions. The authors have adopted different research approaches. N. M. Mavrodina, preparing a catalogue of works exported from Russia, focuses mainly on the activities of Imperial stone-carving factories. The monograph by L. A. Budrina, on the other hand, focuses on the identification and study of carvings and their history; it also offers insights into the role of stone-carved objects in the formation of the image of the Russian state, and describes the main mechanisms that contributed to the formation of a fashion for Russian stone carving abroad. The two reviewed works offer a significant contribution to the historiography of stone carving art, as well as the role of works of art in creating the image of a country or region and their place in the formation of a single European art market.

Tale and Parable: Theorizing Fictions in the Old EnglishBoethius
Authors: Lorden Jennifer A.
Published: June 2021

Scholarship has often considered the concept of fiction a modern phenomenon. But the Old EnglishBoethiusteaches us that medieval people could certainly tell that a fictional story was a lie, although it was hard for them to explain why it was all right that it was a lie—this is the problem the Old EnglishBoethiusaddresses for the first time in the history of the English language. In translating Boethius's sixth-centuryConsolation of Philosophy, the ninth-century Old EnglishBoethiusoffers explanatory comments on its source's narrative exempla drawn from classical myth. While some of these comments explain stories unfamiliar to early medieval English audiences, others consider how such “false stories” may be read and experienced by those properly prepared to encounter them. In so doing, the Old EnglishBoethiusmust adopt and adapt a terminology for fiction that is unique in the extant corpus of Old English writing.

Published: June 2021

The problem of modifying carbon nanotubes (CNTs) by functional groups is relevant in connection with the intensive development of the nanoindustry, in particular, nano- and microelectronics. For example, a modified nanotube can be used as a sensor device element for detecting microenvironments of various substances, in particular, metals included in salts and alkalis. The paper discusses the possibility of creating a highly efficient sensor using single-walled carbon nanotubes as a sensitive element, the surface of which is modified with the functional nitro group —NO2. Quantum-chemical research of the process of attaching a nitro group to the outer surface of a single-walled CNTs of the (6, 0) type were carried out, which proved the possibility of modifying CNTs and the formation of a bond between the
—NO2 group and the carbon atom of the nanotube surface. The results of computer simulation of the interaction process of a surface-modified carbon nanotube with alkali metal atoms (lithium, sodium, potassium) are presented. The sensory interaction of a modified carbon nanosystem with selected metal atoms was investigated, which proved the possibility of identifying these atoms using a nanotubular system that can act as a sensor device element. When interacting with alkali metal atoms in the “СNT – NO2” complex, the number of major carriers increases due to the transfer of electron density from metal atoms to the modified CNTs. The results presented in this paper were obtained using the molecular cluster model and the DFT calculation method with the exchange-correlation functional B3LYP (valence split basis set 6-31G).

Published: June 2021

Research purpose: The aim of the study was to examine the features of the educational concept of the family in mutual understanding with middle school children with different levels of physical activity.

Material and Methods. 212 students aged 11-12 years, including 104 students (48 girls and 56 boys) who are not involved in sports and 108 students who go in for sports (36 girls and 72 boys). The following research methods were used to solve the problems set in the work: analysis and generalization of scientific and methodological literature data; content analysis; method of comparison; sociological methods of research (questionnaire “My family”); methods of mathematical statistics. 

Results. The results of the testing of boys and girls revealed the following 8 factors of upbringing in the family: severity; fostering independence; mother or father domination; attitude to school and teachers; cruelty; relationships in the family; mutual assistance; community of interests. The rating of the factors of upbringing that affect the level of understanding in the family of girls aged 11-12 years, determines that in those who do not go in for sports “rigor and demanding attitude in upbringing” is in the first place, and in the second - “common interests”, while for girls who go in for sports “mutual assistance in the family” is in the first place and in the second “rigor and demanding attitude in upbringing”. The results of the definition of mutual understanding in the family show that the “successful” level was mostly determined by 57.14% of boys aged 11-12 who go in for sports, and the lowest percentage is noted for boys aged 11-12 years old who do not go in for sports (22.22%). Boys and girls who do not play sports are characterized by a “less prosperous” level of mutual understanding in the family (61.11 and 66.67%, respectively).

Conclusions. The socialization of students in the micro and macro environment through the formation of values in the field of physical culture and sports is ensured by the following factors: rigor, fostering initiative, attitude towards school, rigidity in upbringing, family relationships, mutual assistance in the interests of the community.

Published: June 2021

During the operation of state district power station, it is necessary to calculate the technical and economic performance (TEP) of the equipment operation based on the results of measuring the parameters of heat carrier flows. In particular, such tasks are solved during thermal (balance, functional) tests of heat and power equipment, as well as during the preparation of monthly technical reports of the state district power station on thermal efficiency. Therefore, the urgent task is to develop the model of calculating the indicators of the thermal efficiency of the equipment of the state district power station using modern computerized tools. Methods of business processes modelling, and mathematical modeling are used to solve this problem. The developed model of the project is based on the principles and approaches of systems analysis. The model is adapted to a specific subject area and allows you to optimize the process of calculating the key parameters of the efficiency of the state district power station operation: power plant capacity, heat load, specific fuel consumption and overall efficiency of the power plant. An information system model was developed to automate the process of calculating the TEP to ensure a more economic operation of equipment due to reducing the time and cost of this process.Based on the analysis of the developed models, a project was developed to automate the process of TEP calculating to ensure more economical equipment operation, to predict equipment repair, and assess the quality of operating personnel work. The paper presents the architecture of the solution of the information system for TEP accounting, the model of the subsystem of calculation modules, the structural diagram of the operation of the data collection module, the interface of designed information system. The developed model of the project for automation of the TPE calculation process allows us to increase the efficiency of the enterprise due to increasing the efficiency and promptness of managerial decisions, reducing fuel costs, saving on consumables, and personnel cuts.
Development of digital twin model of underground electric cable: thermal part of the problem
Authors: Kutumov Yu.D. , Mizonov V.E. , Tikhonov A.I. , Shadrikova T.Yu.
Published: June 2021

Innovative technologies of generative design using the concept of digital twins of the designed objects play an important role in growing digitalization trend of project activities. The digital twin of an object is the object simulation model with high accuracy of mathematical description. It is used to solve the problems of regime and structural optimization of the object. Usually, generative design technologies are implemented using 3D models of physical fields. And specialized packages which have high requirements for computer resources and user skills are used. At the same time, quite often the object for which the digital twin model is developed consists of several subsystems that allow relatively independent modeling. A one-dimensional model of the thermal process cannot provide the required accuracy, but a 2D-model is quite sufficient for this purpose. The development of such a model that combines the required accuracy, and low cost of machine time is currently topical scientific and practical problem. The method of mathematical modeling is used to solve this problem. The model uses the mathematical apparatus of the Markov chain theory. The model is two-dimensional and is adapted to the multi-layer environment representing the soil, in a separate cell of which a non-stationary heat source may be found. Heat passage through the surrounding soil is described in terms of thermal conductivity, and the heat exchange with the environment is described in terms of heat transfer. The influence of the parameters on the process flow is studied by numerical methods. At this stage of the study, experimental verification of the model is not expected. A mathematical two-dimensional model of digital twin of underground electric cable has been developed. It allows us to predict the cable temperature and its distribution in the surrounding soil. The assessment of thermal state of the power transmission line is given according to the power and the depth of the heat source location. It is found that the results of simulation modeling are consistent with the physical concepts of the process. The results obtained are of scientific novelty, since they are based on a universal modeling algorithm and allow us to describe the transients in the object under study, which is a part of the digital twin of the underground cable. The model is easy to use and requires little machine time. It can be easily used in generative design practice.
Esports Clubs’ Work in Media Spaces: Distinctive Features
Authors: Petryk Oleksandr , Meleshchenko Alexander , Volobuieva Anastasiia
Published: June 2021

On 7 May 2015, the term “esports” was officially added to one of the most extensive online English dictionaries “Dictionary.com.” The dictionary gives the following definition of the term “esports”: “competitive tournaments of video games, especially among professional gamers” (IGN, 2015). The history of esports began in the late 20th century with the game Quake, which allowed users to play together through a LAN or internet network. Since then, a tremendous number of new esports leagues have emerged. Every year, game publishers promote esports disciplines; create a media space around them, and make competitively oriented games, creating an active audience. The popularity of computer-based esports grows each year at an increasing speed. Therefore, it is not surprising that the traditional for typical sports (football, basketball, volleyball, etc.) model of interaction between professional players (esports athletes) and sports clubs (esports organizations) emerged quite rapidly. This interaction aims to optimize the training process to increase athletic achievements and develop the media component for players and clubs. This article analyzes how esports clubs function in media spaces: their goals, tools, strategies, results, and development prospects on the examples and experience of professional esports organizations in Germany, Finland, and China.
Ray-synthetic seismograms forSHwaves in anelastic media
Authors: Krebes E. S. , Hron F.
Published: June 2021

abstract

The linear theory of viscoelasticity is used to study the effects of anelasticity on SH body waves propagating through a layered medium. The mathematical properties of SH waves in a viscoelastic medium are outlined. Reflection and transmission coefficients for SH plane waves impinging upon a plane boundary separating two anelastic media are calculated and compared with the coefficients for the perfectly elastic case. Synthetic seismograms for teleseismic SH body waves are computed for a plane-layered crustal model in both the elastic and anelastic cases, using a ray theory approach.
A probability model for regional focal mechanism solutions
Authors: Brillinger D. R. , Udias A. , Bolt B. A.
Published: June 2021

abstract

The increase in the number of determinations of fault-plane solutions and their use for inferences on regional and local tectonics and stress fields makes it advisable to treat them in a standard way in groups on a regional basis. Probability models for joint group estimation of the shear dislocations, involving data from I earthquakes and J observations of the same region, are presented. The general model gives the probability πij of reading a compression (Yij = 1) for the P wave from event i at station j as Prob { Y i j = 1 } = γ i + ( 1 − 2 γ i ) Φ ( ρ i A i j ) where γ and ρ are precision parameters and Φ is the normal cumulative.

This probability depends on Aij (θ), the theoretical amplitudes from a particular orientation of the greatest and least axes of principal stress for the regional solution. Estimates of the principal stress axes T and P and their variances are computed by constructing a loss function based on the likelihood. The algorithm allows for the estimation of a mean regional solution and one for each event. A treatment of measures of fit and the winnowing of clusters of solutions is given. The resulting program has been applied to the determination of the regional solution and exceptional mechanisms for the main shock and 25 aftershocks of the great 1964 Alaskan earthquake and 19 small earthquakes in Bear Valley, California.
A semi-Markov model for characterizing recurrence of great earthquakes
Authors: Patwardhan Ashok S. , Kulkarni Ram B. , Tocher Don
Published: June 2021

abstract

A semi-Markov model estimating the waiting times and magnitudes of large earthquakes is proposed. The model defines a discrete-time, discrete-state process in which successive state occupancies are governed by the transition probabilities of the Markov process. The stay in any state is described by an integer-valued random variable that depends on the presently occupied state and the state to which the next transition is made. Basic parameters of the model are the transition probabilities for successive states, the holding time distribution, and the initial conditions (the magnitude of the most recent earthquake and the time elapsed since then).

The model was tested by examining compatibility with historical seismicity data for large earthquakes in the circum-Pacific belt. The examination showed reasonable agreement between the calculated and actual waiting times and earthquake magnitudes. The proposed procedure provides a more consistent model of the physical process of gradual accumulation of strain and its intermittent, nonuniform release through large earthquakes and can be applied in the evaluation of seismic risk.
Preliminary body-wave analysis of the St. Elias, Alaska earthquake of February 28, 1979

abstract

Employing a new technique for the body-wave analysis of shallow-focus earthquakes, we have made a preliminary analysis of the St. Elias, Alaska earthquake of February 28, 1979, using five long-period P and S waves recorded at three WWSSN stations and at Palisades, New York. Using a well determined focal mechanism and an average source depth of ≈ 11 km, the interference of the depth phases (i.e., pP and sP, or sS) has been deconvolved from the recorded pulse shapes to obtain velocity and displacement pulse shapes as they would appear if the earthquake had occurred within an infinite medium. These “approximate whole space” pulse shapes indicate that the rupture contained three distinct subevents as well as a small initial event which preceded this subevent sequence by about 7 sec. From the pulse rise times of the subevents, their rupture lengths are estimated as 12, 27, and 17 km, assuming that the subevent rupture velocity was 3 km/sec. Overall, the earthquake ruptured ≈ 60 km to the southeast with an average rupture velocity of 2.2 km/sec. The cumulative body-wave moment for the whole event, 1.2 × 1027 dyne-cm, is substantially smaller than the surface-wave moments reported by Lahr et al. (1979) of 5 × 1027 dyne-cm. The moments of the subevents are estimated to be 0.6, 3.2, and 7.5 × 1026 dyne-cm, respectively.
Observations of the Coyote Lake, California earthquake sequence of August 6, 1979

abstract

At 1705 UTC on August 6, 1979, a strong earthquake (ML = 5.9) occurred along the Calaveras fault zone south of Coyote Lake about 110 km southeast of San Francisco. This strong earthquake had an aftershock sequence of 31 events (2.4 ≦ ML ≦ 4.4) during August 1979. No foreshocks (ML ≧ 1.5) were observed in the 3 months prior to the main shock.

The local magnitude (ML = 5.9) and the seismic moment (Mo = 6 × 1024 dyne-cm from the SH pulse) for the main shock were determined from the 100 × torsion and 3-component ultra-long period seismographs located at Berkeley. Local magnitudes are determined for the aftershocks from the maximum trace amplitudes on the Wood-Anderson torsion seismograms recorded at Berkeley (Δ ≊ 110 km).

Temporal and spatial characteristics of the aftershock sequence are presented and discussed. Some key observations are: (1) the first six aftershocks (ML ≧ 2.4) proceed along the fault zone progressively to the south of the main shock; (2) all of the aftershocks (ML ≧ 2.4) to the south of the largest aftershock (ML = 4.4) have a different focal mechanism than the aftershocks to the north; (3) no aftershocks (ML ≧ 2.4) were observed significantly to the north of the main shock for the first 5 days of the sequence; and (4) the b-value (0.70 ± 0.17) for the aftershock sequence is not significantly different from the average b-value (0.88 ± 0.08) calculated for the Calaveras fault zone from 16 yr of data.
Expected earthquake magnitude from a fault

Published: June 2021

abstract

The estimation of the most likely magnitude M of an earthquake related to a fault is often based on the regressional analysis of the data on M and associated length of the fault L. Recently, Wyss has cogently argued for the use of the area of the fault A rather than L. Based on published worldwide high quality data, we have carried out straight-line and quadratic regressions of M on A ignoring as well as considering the probable errors in the data. The quadratic regressional analysis with errors is based on an approximate theory. The estimates of the most likely magnitude obtained from the regressional analyses assuming reasonable errors in data and ignoring those errors are not significantly different.
Evaluation ofStoPamplitude rations for determining focal mechanisms from regional network observations
Authors: Kisslinger Carl
Published: June 2021

abstract

The ratios of the amplitudes of SV to P, as recorded on vertical component seismographs near the earthquake, provide a means of determining the focal mechanism. The observed ratios are compared with values calculated on the basis of dislocation theory, with the effects of transmission across boundaries and incidence on the free surface approximately accounted for by plane-wave coefficients. A search is made for the strike and dip of the fault that provides a fit to as many of the stations as possible, for the direction of fault slip assumped. The direction of slip may also be treated as a free parameter to be determined, but the theoretical results are especially simple for pure strike-slip or pure dip-slip faulting. The technique has been applied to the analysis of events in three settings, in which pure thrusting, pure strike-slip, and pure normal faulting could be assumed. The utility and the limitations of the method are illustrated by these examples. The important limitations are that the method cannot distinguish between conjugate mechanisms or show the sense of slip on the fault. It also has a weak resolution of strike for some commonly occurring mechanisms, so that the solution may depend on the readings at only a few stations.

The method has been used to pick out a group of foreshocks to an Aleutian Islands earthquake and to provide a focal mechanism for an event in the Rhine graben, at a place where such information is lacking and needed. A study of 15 central California earthquakes revealed no changes in fault plane orientation or in relative attenuation of P and S waves during 1 yr prior to a magnitude 5 earthquake.
Seismic activity on the southern Calaveras Fault in central California

Published: June 2021

abstract

Cumulative seismic moment ΣM0 for earthquake on 50-km-long creeping section of the Calaveras Fault from near Mount Hamilton southeast to San Felipe Lake correlates with mapped fault-trace characteristics. In general, ΣM0 is lower at the left-stepping offset in the trace at the south end of Anderson Lake and along linear segments of the fault than near right-stepping offsets and bends in the trace and intersections of the Calaveras with other faults. Rupture expansion for the August 6, 1979 Coyote Lake sequence main shock, 10 km NNE of Gilroy, California, was unilateral to the southeast (Archuleta, 1979) away from the right-stepping offset in the fault trace near its epicenter. Rupture expansion for the two felt shocks (ML 4.2 and ML 3.9) on August 29, 1978 located 112 km apart near Halls Valley east of San Jose was unilateral for each away from the other, suggesting the existence of a rupture-expansion blocking discontinuity between them. The correlations of seismic activity and fault-trace characteristics are similar to those for shocks along the creeping section of the San Andreas Fault in central California and suggest that the specific “stuck” and “creeping” patch model of Bakun et al. (1980) developed for the San Andreas is applicable to the creeping Calaveras Fault as well.

Cumulative seismic moment (January 1, 1969 to August 6, 1979) within the 16-km-long 1979 Coyote Lake sequence aftershock zone was less than that near the fault-trace discontinuities at its ends. Microearthquakes along the Calaveras Fault near the Coyote Lake aftershock zone increased before the sequence beginning with a cluster on June 22, 1978 near the southeast end of the aftershock zone. A similar seismicity pattern preceded the August 29, 1978 shocks and the ML 4.5 May 8, 1979 shock near Halls Valley.
Simulation of long-period, near-field motion for the great California earthquake of 1857
Authors: Bouchon Michel , Aki Keiiti
Published: June 2021

abstract

Using the fault slip determined by Sieh (1978a), the great 1857 California earthquake is modeled as a propagating fault buried in a realistic medium consisting of a two-layer crust overlying the mantle. The computation is carried out by the discrete wavenumber representation method (Bouchon, 1979). The resulting motion is almost purely horizontal throughout central and southern California, and, at most of the locations, the direction of severe ground shaking is oriented NE-SW. In the Los Angeles area, the peak displacement is about 30 cm, and the duration of severe ground motion is about 75 sec. Since our model does not include the effect of incoherent rupture propagation, our estimate should be considered as a lower bound. The simulated seismic motions are presented in the form of three-dimensional snapshots as well as in the usual form of time series at selected locations. The resultant near-field seismograms show a great diversity in the characteristic of motion as pointed out for actual near-field accelerograms by Hudson (1976). Our simulated motions appear to be in harmony with the description of the effect of the 1857 earthquake by contemporary accounts compiled by Agnew and Sieh (1978).
The November 14 to December 25, 1979 Ghaenat earthquakes of northeast Iran and their tectonic implications
Authors: Haghipour A. , Amidi M.

abstract

A series of shallow earthquakes occurred in northeast Iran starting on November 14, 1979. The sequence includes two destructive earthquakes which occurred on November 14 and 27. In both cases, ground rupture developed along capable faults through the bedrock and Quaternary deposits. The November 14 earthquake was associated with a 20-km N-S trending right-lateral faulting. The November 27 earthquake accompanied a 60-km E-W trending left-lateral fault rupture. Also, during the second earthquake, the northern end of the earlier rupture continued northeastward to align with the eastern end of the second rupture. The result of the fault displacements of both earthquakes is relative subsidence with northeastward/eastward motion of the southwestern block.

The earthquakes are located in the northeast corner of the Lut Block (an eastern fragment of central Iran) and included in the main structural zone of the Central Domain extended from Iran to Central Asia. The recent earthquakes are located in the highly seismic area of northeast Iran where the rate of seismicity has increased markedly in the past decade.

Based on structural considerations of earthquake data, the rupture types their recent migration of locations show that a recent relative eastward motion for east-central Iran blocks resulted from northeast compressional movements and shortening of the Iranian Plateau.
