Myxedema crisis and ovarian hyperstimulation in a child with Down syndrome
Authors: Abraham Maria Susan , Sampathkumar Geethalakshmi , Narayanan Rajeshwari , Jagannathan Prahada 
Published: September 2021

Abstract

Objectives
Myxedema crisis, a fatal complication of severe hypothyroidism, is extremely rare in children and treatment guidelines are lacking. Since availability of intravenous levothyroxine is limited in resource poor settings, myxedema crisis can be treated with oral levothyroxine and/or oral liothyronine (if necessary), in the absence of cardiac risk factors, thus hastening the recovery and significantly decreasing the associated morbidity and mortality. In the background of untreated hypothyroidism, a possible association of ovarian hyperstimulation syndrome (OHSS) and reactive pituitary hyperplasia should be kept in mind, thus preventing unnecessary interventions.

Case presentation
A 13-year-old girl child with Down syndrome, presented with myxedema crisis, as initial presentation of untreated hypothyroidism.

Conclusions
Annual screening, timely diagnosis of hypothyroidism, and early initiation of thyroid hormone supplementation will prevent associated physical and neurocognitive morbidity in children, especially those with Down syndrome. Importance of oral liothyronine supplementation in myxedema crisis, has been highlighted in this case report.
Territoriality and Settlement in Southern France in the Early Neolithic: Diversity as a Strategy?

Published: September 2021

AbstractIn the western Mediterranean, the question of the settlement patterns of the first farming communities remains a much debated issue. Frequently compared with the LBK model, based on hundreds of well-documented villages, the settlement organization of the Impressed Ware complex is still poorly characterized and highly diversified. New data obtained in Southern France (Languedoc) may shed light on this matter, based on new excavations, revised data, and a multi-proxy perspective (site type, domestic area, food supply strategies, activities, spheres of acquisition of raw material, and so forth). Rather than reproducing a pattern of site locations and settlement structuring, it seems that these Early Neolithic groups sought to optimize the location and structuring of their settlements in relation to the specific characteristics of the surrounding environment and available resources. We therefore propose that the diversity observed in the settlement organization of these first farming communities is a reflection of a social organization well-adapted to the diversity of the ecosystem.
Corona, Bankeinlagen und Verwahrentgelte
Authors: Reichel Richard 
Published: September 2021

Abstract
Die Corona-Pandemie hat das Konsum- und Sparverhalten der Deutschen schockartig verändert. Lockdowns und die allgemeine Unsicherheit über den Fortgang der Pandemie haben zu einem starken Anstieg des Vorsorgesparens geführt. Große Teile des zusätzlichen Sparaufkommens sind auf Giro- und Geldmarktkonten angelegt und unterliegen damit den immer häufiger anzutreffenden Negativzinsen auf Bankeinlagen. Die deutschen Kreditgenossenschaften sind als traditionell passivlastige Institute von diesen Entwicklungen besonders betroffen.

Synthesis, crystal structure and selected properties of K2[Ni(dien)2]{[Ni(dien)]2Ta6O19}·11 H2O
Authors: Krause Dana-Céline , Mangelsen Sebastian , Näther Christian , Bensch Wolfgang 
Published: September 2021

Abstract
The new compound K2[Ni(dien)2]{[Ni(dien)]2Ta6O19}·11 H2O crystallized at room temperature applying a diffusion based reaction in a H2O/DMSO mixture using K8{Ta6O19}·16 H2O, Ni(NO3)2·6H2O and dien (diethylenetriamine). In the crystal structure, the Lindqvist-type anion [Ta6O19]8– is structurally expanded by two octahedrally Ni2+-centered complexes via three Ni–µ
2-O–Ta bonds thus generating the new {[Ni(dien)]2Ta6O19}4– anion. Two KO8 polyhedra share a common edge to form a K2O14 moiety, which connects the {[Ni(dien)]2Ta6O19}4– cluster shells into chains. The isolated [Ni(dien)2]2+ complexes are located in voids generated by the structural arrangement of the chains. An extended hydrogen bonding network between the different constituents generates a 3D network. The crystal water molecules can be thermally removed to form a highly crystalline dehydrated compound. Partial water uptake leads to the formation of a crystalline intermediate with a reduced unit cell volume compared to the fully hydrated sample. Water sorption experiments demonstrate that the fully dehydrated sample can be fully reconverted to the hydrated compound. The crystal field splitting parameters for the octahedrally coordinated Ni2+-centered complexes have been evaluated from an UV/Vis spectrum yielding D
q = 1056 cm−1 and B = 887 cm−1.

A TANULMÁNY CÉLJA
A tanulmány célja a magyar háztartások portfólióválasztási szokásainak vizsgálata a nyugdíjkorhatárt elérő 65-80 éves korosztályban. Arra a kutatási kérdésre kerestem a választ, hogy a vizsgált korosztályba tartozó válaszadók milyen preferenciák szerint választják ki a számukra megfelelő portfóliót, hiszen a portfólió választás életciklus elmélete a nyugdíjkorhatárt elérő korosztály tekintetében nem vezet egyértelmű következtetésre.
ALKALMAZOTT MÓDSZERTAN
A portfólióválasztás életciklus elméletéből következő, empirikusan is jól tesztelhető kutatási kérdés megválaszolása érdekében egy ordinális logisztikus regressziós modell segítségével vizsgáltam meg a portfólió választási szokásokat az életciklus különböző szakaszaiban az iskolai végzettség és a kockázati magatartás függvényében.
A KUTATÁS LEGFONTOSABB EREDMÉNYEI, ÚJDONSÁGOK
Megállapítottam, hogy az iskolai végzettség és a kockázati magatartás hatásait kiszűrve a 65-80 éves korosztályba tartozók szignifikánsan nagyobb valószínűséggel választanak kevésbé kockázatos portfóliókat a fiatalabbakhoz képest. Ezen felül megmutattam, hogy a részvényeket nem tartalmazó portfóliókat választók körében a 65-80 éves korosztály aránya szignifikánsan magasabb.
GYAKORLATI JAVASLATOK
A tanulmányban bemutatott eredmények iránymutatásként szolgálnak a magyar háztartások nyugdíjkorhatárt követő életszakaszban megfigyelhető portfólióválasztási szokásainak vonatkozásában, ezzel kiegészítve a portfólió választás életciklus elméletének következtetéseit.

Abstract
In this study, we focused on the emergence of extensively drug-resistant (XDR), pandrug-resistant (PDR), and hypervirulent Klebsiella pneumoniae (hvKP) in Iran. During 2018 to 2020 a total of 52 K. pneumoniae isolates were collected from different clinical specimens. The hvKP isolates were identified by PCR amplification of virulence and capsular serotype-specific genes. Hypermucoviscous K. pneumoniae (hmKP) were identified by string test. Carbapenem-resistant hvKP (CR-hvKP), multidrug-resistant hvKP (MDR-hvKP), extensively drug-resistant hvKP (XDR-hvKP), and pandrug-resistant hvKP (PDR-hvKP) were determined by disc diffusion method, Carba-NP test and PCR method. XDR-hvKP isolates were typed by multilocus sequence typing (MLST). Among all K. pneumoniae isolates 14 (26.9%) were identified as hvKP and 78.6% (11/14) of them were hmKP however, none of the classic K. pneumoniae (cKP) isolates were hmKP. The predominant capsular serotype of hvKP was K2 (42.85%) followed by K1 (35.71%). The prevalence of MDR-hvKP, XDR-hvKP and PDR-hvKP isolates were 6 (42.9%), 5 (35.7%) and 1 (7.1%), respectively. ESBL production was found in 85.7% of hvKP isolates and most of them carried bla
TEM gene (78.6%) and 6 isolates (42.9%) were CR-hvKP. Among hvKP isolates, 1 (7.1%), 2 (14.3%), 3 (21.4%), 8 (28.6%), and 11 (78.6%) carried bla
NDM-6,
bla
OXA-48, bla
CTX-M,
bla
SHV, and bla
TEM genes, respectively. According to MLST analysis, 2, 1, 1, and 1 XDR-hvKP isolates belonged to ST15, ST377, ST442, and ST147, respectively. The occurrence of such isolates is deeply concerning due to the combination of hypervirulence and extensively drug-resistance or pandrug-resistance.
The “shadow” from a velocity reversal
Authors: Hron M. , Chapman C. H. 
Published: September 2021

abstract
The “shadow” from an Epstein “sech2” profile is caused by exponential decay of amplitude. The decay constant, which is independent of frequency, is identical with that obtained from the classical ray theory. The spectral amplitudes and theoretical seismograms evaluated numerically show the effect of the reversal on the acoustic wave propagation.
Torsional overtone dispersion from correlations of S waves to SS waves
Authors: Brune James N. , Gilbert Freeman 
Published: September 2021

abstract
This paper presents SH overtone dispersion data obtained by using the phase correlation method of Brune (1964). The data augment the set provided by longer-period spheroidal and toroidal mode data and travel-time data. A major advantage of the phase-correlation method over travel-time data is the elimination, to first order, of source effects and source-region bias. The overtone data are consistent with lower-order spheroidal overtone data indicating a base-line correction of 4.0 ± 0.9 sec to the S-wave travel-time data of Hales and Roberts (1970). These and other fundamental-mode and overtone data, travel-time data, and mass and moment of inertia comprise 497 gross earth data and represent one more step in the march toward a spherically averaged earth model.
Stability of P an S velocities from Central California quarry blasts
Authors: McEvilly T. V. , Johnson L. R. 
Published: September 2021

abstract
Travel times of crustal P and S waves from 70 quarry blasts in Central California between July 1961 and June 1973 have been measured for seven paths 46 to 168 km long passing in several cases within 10 km of hypocenters of moderate (ML 4.5 to 5.4) earthquakes. All P and S times and their ratios TS/TP lie within 2.3 per cent of the mean values and over 97 per cent of the TS/TP ratios lie within 1 per cent of the mean values. Variations can be explained by reading errors and uncertainties in source times and locations. There are no indications of velocity variations related to earthquake occurrences. Mean VP/VS ratios range from 1.73 to 1.84 for the various paths. The phenomenon of premonitory dilatancy accompanied by a 10 to 20 per cent reduction in VP or VP/VS cannot be reconciled with these observations unless the affected source regions have lateral dimensions less than about 5 km for these moderate strike-slip earthquakes.
Upper mantle shear-wave velocity structure in the Japan region
Authors: Kaila K. L. , Krishna V. G. , Narain Hari 
Published: September 2021

abstract
The upper mantle shear-wave velocity structure in the Japan region has been determined from S travel times of 101 earthquakes with focal depths varying from 40 to 600 km, using a new analytical method given by Kaila (1969). In southwestern Japan, the S velocity obtained as 4.35 km/sec at a 40-km depth remains almost constant to a depth of about 170 km. The shear velocity in northeastern Japan increases linearly from 4.42 km/sec at a depth of 45 km to 4.62 km/sec at a depth of 145-km. For central Japan, the S velocity determined as 4.41 km/sec at a 40-km depth increases linearly to 4.55 km/sec at a 170-km depth, followed by a slight decrease in the velocity gradient, with velocity still increasing linearly to 4.68 km/sec at a depth of 345 km. At this transition depth, there is a first-order velocity discontinuity, the velocity increasing from 4.68 to 4.92 km/sec. Below this depth, velocity again increases linearly from 4.92 to 5.04 km/sec at a depth of 600 km. The shear velocities at depths between 440 to 640 km in Japan are found to be extremely low in comparison to those of Jeffreys (1939), Gutenberg (1959), and Arnold (1967). These low S velocities can explain satisfactorily the late S arrivals from shallow earthquakes between Δ = 20° to 30° as observed in the Japanese region. Graphs have been drawn to show the variation with depth of Δ*, the epicentral distance to the inflection point, Δ1, Δ2, (Δ2 − Δ1), ptrue =∂T/∂Δ, and αS = (T − pΔ) at the inflection point as obtained from the S-wave travel-time analysis.
Seismic investigation of a san francisco bay mud site
Authors: Warrick Richard E. 
Published: September 2021

abstract
Measurements were made of the shear- and compressional-wave velocities necessary to determine the seismic response of a site on the edge of the San Francisco Bay, California. The shear wave is the most difficult to isolate because of the complications of earlier arriving energy. Downhole and surface measurements yielded shear-wave velocities of 90 to 130 m/sec and compressional-wave velocities of 1,400 m/sec for soft mud. The underlying older sediments had interval shear-wave velocities of 270 to 380 m/sec, increasing with depth. The corresponding P velocities for the older sediments were 1,600 to 1,840 m/sec. The horizontal traction technique of shear-wave generation proved to be the most successful of the methods tested.
Seismicity of the Middle America arc-trench system near Managua, Nicaragua
Authors: Dewey James W. , Algermissen S. T. 
Published: September 2021

AbstractHypocenters of earthquakes occurring during the period 1950 through 1972 in the Middle America arc-trench system near Managua, Nicaragua, have been relocated by the method of joint hypocenter determination (JHD) or the master event method with the Managua earthquake of December 23, 1972 as the calibration event. The relocated hypocenters show a considerably narrower Benioff zone than previous hypocenters of the same earthquakes and clearly separate shallow-focus volcanic terrane earthquakes of the type which struck Managua from the Benioff zone earthquakes. The shallow-focus volcanic terrane earthquakes are probably caused by tectonic conditions associated with the formation of the Nicaraguan depression or the principal chain of Quaternary volcanoes. The Managua earthquake of December 23, 1972 may have occurred as a consequence of slippage along a transform fault zone which connects offset segments of the chain of Quaternary volcanoes; the volcanic chain is then taken to be the surface expression of a secondary spreading zone which lies above the Benioff zone of the Middle America arc-trench system. Alternatively, the recent Managua earthquake may have occurred as a consequence of regional east-west tension in the Nicaraguan depression.
Seismic source and transmission functions from underground nuclear explosions
Authors: Dahlman Ola 
Published: September 2021

abstract
A model is presented for the simultaneous detemination of the relative variation in transmission properties to different stations and of the relative differences between the seismic sources for closely spaced underground nuclear explosions recorded by a fixed seismological station network. The model is applied to short-period data reported from 24 globally distributed stations from 12 underground nuclear explosions with known yields at Nevada Test Site. The obtained transmission functions vary within a factor of 10 between the different stations and show a weak decrease with epicenter distance and little correlation with the Gutenberg amplitude-distance curve. The relative source functions for 10 explosions in tuff and rhyolite, with yields in the range 16 to 1,200 kt, are with good correlation proportional to explosion yield to 0.9. Two theoretical source-function models, one by Haskell (1967) and one by Mueller and Murphy (1971a), are compared with each other and they agree well for frequencies around 1 Hz and for yields in the range 3 to 300 kt. The Haskell model for tuff is modified to be more compatible with the models for salt, granite and alluvium. The Haskell model predicts stronger variation of the source functions with frequency and yield than the Mueller-Murphy model. The observed relative source functions are compared with the theoretical source functions obtained from the two source models. The agreement is fairly good but the relative decrease of the source functions at yields above 300 kt predicted by the theoretical models is not observed.
Time functions appropriate for deep earthquakes
Authors: Burdick L. J. , Helmberger D. V. 
Published: September 2021

Abstract
The seismic signatures of isolated body phases from many deep-focus earthquakes were analyzed in the time domain. Most shocks were found to be multiple events when examined in detail. The time history derived from P waves for single events predict synthetic S-wave shapes that match the observations, indicating compatibility with shear dislocation theory. Several other features of source functions in the time domain have been brought to light.
Dilatancy and spatial distribution of aftershocks
Authors: Gupta Indra N. 
Published: September 2021

abstract
The pre-earthquake dilatancy, postulated to explain certain premonitory seismic velocity changes, may provide a preferred direction of groundwater flow persisting after the occurrence of a shallow earthquake. This direction is parallel to and nearly coincident with the compressive stress axis associated with the focal mechanism of the principal shock. Aftershocks may result from a redistribution of pore pressure and fluid flow not only along faults but also along this direction of relatively large permeability. This suggestion provides a possible explanation for certain observations of aftershocks aligned along the compressive stress direction.
First strong-motion instrumentation in Hawaii: With results from the earthquake of April 26, 1973
Authors: Adams W. M. 
Published: September 2021

abstract
On April 26, 1973, an earthquake with magnitude of 614 occurred at a depth of 40 km below Honomu (north of Hilo). Serendipitously, in the preceding February, one SMA-1 accelerograph and one Wilmot seismoscope were installed near Waikiki on the island of Oahu. Also, one SMA-1 accelerograph and three Wilmot seismoscopes were installed on the island of Hawaii. The records from these instruments provided the first strong-motion data for the State of Hawaii. The motion was dominantly horizontal. This finding explains the extensive damage to the Hilo area, reported to be about 6 million dollars.
Definition and identification of seismic events in the USSR in 1971
Authors: Dahlman Ola , Israelson Hans , Austegard Atle , Hörnström Gunnel 
Published: September 2021

abstractSeismic events reported to have occurred in the USSR in 1971 are studied to assess the seismic monitoring problem as it may occur in the context of a complete test-ban treaty. Available epicenter data of a total of 199 events, 180 earthquakes and 19 explosions, are presented. Focal depth estimates reported by the National Oceanic and Atmospheric Administration, U.S., and the Institute of Physics of the Earth, Moscow, are compared. Identification parameters determined using short- and long-period data from Hagfors Observatory and supplementary short-period data from the Yellowknife array station in Canada are presented. To study the combined operative efficiency and applicability of available identification parameters, the reported depth estimates and the identification data are assessed in a defined way.
Time functions appropriate for some aftershocks of the point Mugu, California earthquake of February 21, 1973
Authors: King David , Helmberger Donald V. 
Published: September 2021

abstract
Broad-band recordings of aftershocks of the Pt. Mugu earthquake at small epicentral distances provided an excellent opportunity to test source models for small earthquakes. Simple events recorded at nearly vertical incidence produced a single P-wave pulse of a duration of about 0.07 sec and a somewhat more complicated S wave with a slightly longer duration. Such events are consistent with a point dislocation source for which Qβ = 100 or for which there is directivity with the fault breaking downward. We attribute the more usual complexities of small earthquake records to multiple events, some of which we observed, layering effects combined with greater epicentral distances, and scattering.
Conversion of Sn to Lg at a continental margin
Authors: Isacks Bryan L. , Stephens Christopher 
Published: September 2021

abstract
Examination of the seismic phase Sn from earthquakes in the West Indies as recorded by numerous stations in eastern North America reveals that a substantial fraction of the short-period energy carried by Sn across the suboceanic lithosphere of the Atlantic is fed into the continental crust near the continental margin and travels into North America as the crustal phase Lg. As distance within the continent increases, the Lg part of the short-period wave train becomes predominant, and can be identified at stations in northern Canada as far as 58° from the sources. Several estimates of the average Q for the attenuation of Lg in eastern North America agree upon values in the range of 600 to 1,400. Hydrophone recordings at Bermuda indicate an average Q as high as 4,000 for the attenuation of Sn in the suboceanic lithosphere. Conversion of Sn to Lg also appears to occur near the margin between the continental U.S. and the Gulf of Mexico. In this case, Sn travels northward across the Gulf from earthquakes located near the border between Mexico and Guatemala.
