Beauveria bassiana (Bal.-Criv.) is an important entomopathogenic fungus being used for the management of various agricultural pests worldwide. However, all strains of B. bassiana may not be effective against whitefly, Bemisia tabaci, or other pests, and strains show diversity in their growth, sporulation, virulence features, and overall bioefficacy. Thus, to select the most effective strain, a comprehensive way needs to be devised. We studied the diversity among the 102 strains of B. bassiana isolated from 19 insect species based on their physiological features, virulence, and molecular phylogeny, to identify promising ones for the management of B. tabaci. Strains showed diversity in mycelial growth, conidial production, and their virulence against B. tabaci nymphs. The highest nymphal mortality (2nd and 3rd instar) was recorded with MTCC-4511 (95.1%), MTCC-6289 (93.8%), and MTCC-4565 (89.9%) at a concentration of 1 × 106 conidia ml−1 under polyhouse conditions. The highest bioefficacy index (BI) was in MTCC-4511 (78.3%), MTCC-4565 (68.2%), and MTCC-4543 (62.1%). MTCC-4511, MTCC-4565, and MTCC-4543 clustered with positive loading of eigenvalues for the first two principal components and the cluster analysis also corresponded well with PCA (principal component analysis) (nymphal mortality and BI). The molecular phylogeny could not draw any distinct relationship between physiological features, the virulence of B. bassiana strains with the host and location. The BI, PCA, and square Euclidean distance cluster were found the most useful tools for selecting potential entomopathogenic strains. The selected strains could be utilized for the management of the B. tabaci nymphal population in the field through the development of effective formulations. Key points: • 102 B. bassiana strains showed diversity in growth and virulence against B. tabaci. • Bioefficacy index, PCA, and SED group are efficient tools for selecting potential strains. • MTCC-4511, 4565, and 4543 chosen as the most virulent strains to kill whitefly nymphs.

This article focuses on the replacement of prison staff in Czechoslovakia and East Germany, later the German Democratic Republic after 1945. The main focus is on the question of how the replacement of prison staff took place, what strategies Czechoslovakia and East Germany used to accomplish this task, and the extent to which local conditions and the overall evolution of the prison systems of the two countries played a role in the process. The other aim of the article is to understand the place of political indoctrination in the staffing of prisons in the two socialist countries and to show how the system of teaching new members of the prison staff changed over time. Comparing the replacement of prison staff shows that although both states were under Soviet influence and transformed their prison systems according to the Soviet model, the implementation of staff changes greatly depended on the distinct political, economic and social conditions of the two states.

Global observations of the ionospheric total electron content (TEC) are used to analyze the development of a moderate geomagnetic storm on November 7, 2022. The effects of the storm in the American and European sectors are compared. Signatures of such large-scale ionospheric structures as storm enhanced density (SED) and tongues of ionization (TOIs) are detected during the storm. [ABSTRACT FROM AUTHOR]

Existing scholarship treats congresses of the ruling communist parties in the Eastern Bloc as staged performances intended to manufacture support and signal new policy trends. This article, using the examples of extraordinary party congresses held during revolutionary times in Poland (1981) and the German Democratic Republic (1989) offers another per¬spective. It looks at the events as spaces where rank-and-file delegates could contest par¬ticular decisions of their organization, while simultaneously straying away from more radi¬cal forms of dissent. This article follows and compares the actions of delegates in both countries by highlighting how they disrupted the agenda of the congresses over the ques¬tion of elite corruption committed by former members of the party leadership and account¬ability for these wrongdoings. These episodes show that anti-corruption was a genuinely important moral preoccupation, as well as an argument for demanding change, and that, during the 1980s, ideas grounded in socialism still possessed major legitimacy.

Even now German society is painfully aware of its past. For German historians and cultural scientists, the problem of overcoming the past is an important topic for discussion. The purpose of this research article is to explore the genesis of the phenomenon of overcoming the past in post-war Germany. To investigate the phenomenon and the development of the concept, the article analyzes the approaches of German historians to the study of this problem from the formation of the Federal Republic of Germany to this day. The research is based on the principles of memory studies to reflect on the problem of guilt and collective responsibility of the Germans for the Nazi era. In 1949–1990 the German society acknowledged Nazi crimes and established memorials. Political disputes on the reassessment of national socialism attracted public attention and transformed memory politics in the country. The author also applies a comparative historical method to determine how this went in two German states, Germany and the GDR. The results of the study show that after the unification of Germany, the concept of overcoming the past has changed and the problem of overcoming the past has got a new dimension in German scientific discourse. As the study has shown, at present not only overcoming the period of National Socialism but also rethinking the SED regime is a significant problem of public historical consciousness and the culture of memory in Germany. This double problem is widely discussed in the media and is finding its way into the collective consciousness and identity of the German people. The article describes and analyzes the specificities of the process of transformation. Scientific discussion of the differences between the understanding of the concept of overcoming the past and its practical applications described in the paper is another finding of the study.

Background: Staphylococcus aureus (S. aureus) is a highly virulent pathogen that causes food-borne illness, food poisoning, skin and soft tissue infections, abscesses, mastitis, and bacteremia. It is common for meat and meat products to become contaminated with S. aureus due to dirty hands, food storage conditions, food production processes, and unhygienic conditions, causing food poisoning. Therefore, we aimed to isolate S. aureus strain from the raw beef and reveal virulence genes and antibiotic resistance profile from isolated S. aureus strains. Methods: In this study, 100 samples of raw beef were collected from 4 major market stalls in Ulaanbaatar city, Mongolia. S. aureus was detected according to the ISO 6888–1:2021 standard, and the nucA gene encoding the species-specific thermonuclease was amplified and confirmed by polymerase chain reaction (PCR). In the strains of S. aureus isolated from the samples, the genes encoding the virulence factors including sea, sed, tsst, eta, etb, and mecA were amplified by multiplex PCR. These genes are encoded staphylococcal enterotoxin A, enterotoxin D, toxic shock syndrome toxin, exotoxin A, exotoxin B and penicillin-binding protein PBP 2A, respectively. Antibiotic sensitivity test was performed by the Kirby–Bauer disc diffusion method. The Clinical and Laboratory Standard Institute guidelines as CLSI M100-S27 was used for analysis of the data. Results: Thirty-five percent of our samples were detected contaminated with of the S. aureus strains. Subsequently, antibiotic resistance was observed in the S. aureus contaminated samples. Among our samples, the highest rates of resistance were determined against ampicillin (97.1%), oxacillin (88.6%), and penicillin (88.6%), respectively. Three genes including mecA, sea, and tsst from six virulence genes were detected in 17% of S. aureus strain-contaminated samples by multiplex PCR. The sed, etb and eta genes were detected in the 2.9%, 11.4% and 5.7% of our samples, respectively. Conclusion: The results show that S. aureus related contamination is high in the raw beef for retail sale and prevalent S. aureus strains are resistant to all antibiotics used. Also, our results have demonstrated that there is a high risk for food poisoning caused by antibiotic resistant S. aureus in the raw beef and it may establish public health issues. Genes encoding for both heat-resistant and nonresistant toxicity factors were detected in the antibiotic resistant S. aureus strains and shown the highly pathogenic. Finally, our study is ensuring to need proper hygienic conditions during beef's preparation and sale. [ABSTRACT FROM AUTHOR]

Classical Turkish music, which has been continuing to be fed with the Middle Ages Islamic world since the 10th century, owes its development to the pieces written by many theorists and composers, especially Fârâbî, İbn-î Sînâ, Safüyüddin Urmevî, Abdülkâdir Merâgî, Bedri Dilşad, Lâdikli Mehmed Çelebi, Abdülbâkî Nâsır Dede, Dimitri Cantemir, Rauf Yektâ. In these pieces, explanations are given on the concept of maqam, the formation of maqam, the factors affecting its formation (caesura, prepotent, course), and its classification. Especially in the pieces having been written since the fifteenth century, there is a distinction in the classification, with the word maqam being mentioned more frequently. In the research, it is aimed to investigate the change in the concept of maqam in Classical Turkish music in the historical process and to see the theoretical approaches of theorists and composers to the concept of maqam. The study, within the framework of maqam definitions and classifications, is limited to the period between the 13th and 20th centuries. In the research, it is seen that the fifteenth century was a transition period as a maqam expression style, and since this century, maqam narrations have been made with note and course focusing rather than quartets and quintuplets.

The economic policy agenda of the SED has often been described as extremely orthodox in nature and—with the exception of a short period in the 1960s—hostile to reform. It is often overlooked that the GDR entertained the largest private sector of any of the CMEA economies up till the early 1980s. Besides the official propaganda, the SED leadership at no point abolished private entrepreneurship completely in the GDR. In this article, I analyze the ambiguous relationship between the state party and private entrepreneurship. I focus particularly on the late 1980s and the role private entrepreneurs were supposed to play in reforming and saving socialism in East Germany. [ABSTRACT FROM AUTHOR]

This paper conducts a multi‐instrument analysis and data assimilation study of midlatitude ionospheric disturbances over the European and North American longitude sectors during a strong geomagnetic storm on 26–28 February 2023. The study uses a set of ground‐based (GNSS receivers, ionosondes) observations, space‐borne (DMSP, GOLD) measurements, and a new TEC‐based ionospheric data assimilation system (TIDAS). We observed a series of distinct storm‐time features with regard to storm‐enhanced density (SED) and subauroral polarization stream (SAPS) as follows: (a) Under multiple ring current intensifications, the storm‐time subauroral ionosphere produced long‐lasting duskside SAPS for ∼36 hr along with considerable dawnside SAPS for several hours. (b) Associated with long‐lived SAPS, strong SED occurred consecutively in the European longitude sector near local noon during a positive ionospheric storm and later in the North American longitude sector near local dusk during a negative ionospheric storm. (c) The 3‐D morphology of SED in multiple longitude sectors was reconstructed using TIDAS data assimilation technique with fine‐scale details, which revealed a narrow ionospheric plasma channel with electron density enhancement and layer uplift. Key Points: The storm‐time subauroral ionosphere produced long‐lasting duskside subauroral polarization stream (SAPS) for ∼36 hr and noticeable dawnside SAPS for several hoursAssociated SED occurred in European longitudes during a positive storm period and then in North America during a negative storm periodThe 3‐D SED morphology in multiple longitude sectors was reconstructed using a new total electron content (TEC)‐based ionospheric data assimilation system [ABSTRACT FROM AUTHOR]

This work investigates mid‐ and low‐latitude ionospheric disturbances over the American sector during a moderate but geo‐effective geomagnetic storm on 13–14 March 2022 (π‐Day storm), using ground‐based Global Navigation Satellite System total electron content data, ionosonde observations, and space‐borne measurements from the Global‐scale Observations of Limb and Disk (GOLD), Swarm, the Defense Meteorological Satellite Program (DMSP), and the Ionospheric Connection Explorer (ICON) satellites. Our results show that this modest but geo‐effective storm created a number of large ionospheric disturbances, especially the dynamic multi‐scale electron density gradient features in the storm main phase as follows: (a) The low‐latitude equatorial ionization anomaly (EIA) exhibited a dramatic storm‐time deformation and reformation, where the EIA crests evolved into a bright equatorial band for 1–2 hr and then quickly separated back into the typical double‐crest structure with a broad crest width and deep equatorial trough. (b) Strong equatorial plasma bubbles (EPBs) occurred with an abnormally high latitude/altitude extension, reaching the geomagnetic latitude of ∼30°, corresponding to an Apex height of 2,600 km above the dip equator. (c) The midlatitude ionosphere experienced a conspicuous storm‐enhanced density (SED) plume structure associated with the subauroral polarization stream (SAPS). This SED/SAPS feature showed an unusual temporal variation that intensified and diminished twice. These distinct mid‐ and low‐latitude ionospheric disturbances could be attributed to the storm‐time electrodynamic effect of electric field perturbation, along with contributions from neutral dynamics and thermospheric composition change. Key Points: A common key driver of storm‐time electric field generated three dynamic ionospheric changes simultaneously from low to subauroral latitudesEquatorial ionization anomaly crests showed merging and separation during interplanetary magnetic field Bz oscillation, and strong equatorial plasma bubbles reached 30° MLAT corresponding to 2,600 km Apex heightSalient storm‐enhanced density associated with subauroral polarization stream occurred in midlatitudes, showing a dynamic temporal variation that intensified and diminished twice [ABSTRACT FROM AUTHOR]

The main goal of the Vera C. Rubin observatory is to perform the 10 year Legacy Survey of Space and Time (LSST). This future state-of-art observatory will open the new window to study billions of galaxies from Local Universe as well as the high redshift objects. In this work we employ simulated LSST observations and uncertainties, based on the 50 385 real galaxies within the redshift range 0 < z < 2.5 from the ELAIS-N1 and COSMOS fields of the Herschel Extragalactic Legacy Project (HELP) survey, to constrain the physical properties of normal star-forming galaxies, such as their star formation rate (SFR), stellar mass (Mstar), and dust luminosity (Ldust). We fit their spectral energy distributions (SEDs) using the Code Investigating GALaxy Emission (CIGALE). The stellar masses estimated based on the LSST measurements agree with the full UV to far-IR SED, while we obtain a clear overestimate of the dust-related properties (SFR, Ldust) estimated with LSST. We investigate the cause of this result and find that it is necessary to employ auxiliary rest-frame mid-IR observations, simulated UV observations, or the far-UV attenuation (AFUV)-Mstar relation to correct for the overestimate.

• The fracture of a new third generation AW2099-T83 alloy was examined. • U and V notched specimens were tested under quasi-static loading. • A machine learning model was successfully used to estimate the fracture loads. • The theory of critical distance was used for estimating the fracture loads. • The strain energy density criterion was used for estimating the fracture loads. Aluminum–lithium (Al–Li) alloys offer superior performance under different conditions that involve mechanical loading, high temperature and corrosive environment. Therefore, Al–Li alloys are being used in the defense, aerospace, and aircraft industries, specifically in structural parts such as fuselage, empennage, and wings. By modifying the chemical composition, a third generation of Al–Li alloys has been introduced to overcome the mechanical and thermal shortcomings of previous Al–Li generations. As structural parts usually contain notches, it is of paramount importance to study the strength of the newly introduced alloys in the presence of such geometrical discontinuities to select the suitable alloy for a particular application. The aim of this work is to analyze the strength of U and V-notched specimens machined from extruded AW2099-T83 Al–Li alloys under quasi-static loading. The fracture stress of specimens with various notch radii and angles were estimated using strain energy density (SED) and the theory of critical distances (TCD) methods. A support vector machine (SVM) regression model was also implemented to assess the applicability of estimating fracture stress using machine learning approaches. The results show an average absolute discrepancy of 6.6 %, 7.8 % and 2.8 % for SED, TCD and SVM methods, respectively. [ABSTRACT FROM AUTHOR]

[Display omitted] • Solar radiation sensitive indicator cards responding with color change. • Intended for personal use and safer outdoor activities. • Radiant dose is determined visually by comparing with printed color scale. • 1 to 4 SED range of radiant exposure doses. • Fabrication up-scaling to roll-to-roll process documented. Although the Earths atmosphere provides substantial reduction of the incident radiant power in the most harmful spectral ranges, excessive exposure of untrained and/or unprotected human skin to solar radiation can easily result into acute and chronic adverse effects onto human skin. In order to reduce these effects, a simple tool for monitoring the incident radiant dose is proposed. We report on the design, development, lab scale fabrication, calibration and the roll-to-roll printing production of a photosensitive indicator cards intended for personal monitoring of solar exposure to which the user has been subjected. Two types of cards are being discussed. The first one is supposed as high sensitive one with a dose response to 1 and 2 SEDs, the second one is a less sensitive with a dose response to 3 and 4 SEDs. The calibration of the cards was performed with polychromatic simulated solar radiation without determining the spectral response, therefore we refer to the device as indicator card, not dosimeters. Moreover, properties of the photosensitive formulation employed for the fabrication of the indicator are presented alongside with the calibration of the printed indicator to dermatologically relevant values of the received solar exposure dose. Special attention is also paid to the large-scale practical production of such indicators by the roll-to-roll printing technology. Mechanical properties, stability, durability, practical utilisation, and other features are critically assessed. [ABSTRACT FROM AUTHOR]

Background: Sunburn is the main avoidable cause of skin cancer. Beach lifeguards spend many hours exposed to the effects of solar radiation during their work day, precisely at times of the year when levels of solar irradiation are highest. The aim of this study is to quantify the risk to beach lifeguards of sun exposure. Methods: A descriptive cross-sectional study was carried out in the Western Costa del Sol, southern Spain, during the summer of 2018. The research subjects were recruited during a skin cancer prevention course for beach lifeguards. All participants were invited to complete a questionnaire on their habits, attitudes, and knowledge related to sun exposure. In addition, ten were specially monitored using personal dosimeters for three consecutive days, and the results were recorded in a photoprotection diary. A descriptive analysis (mean and standard deviation for the quantitative variables) was performed, and inter-group differences were evaluated using the Mann–Whitney U test. Results: Two hundred fifteen lifeguards completed the questionnaire, and 109 met the criteria for inclusion in this analysis. The mean age was 23.8 years (SD: 5.1), 78.0% were male, 71.5% were phototype III or IV (Fitzpatrick's phototype), and 77.1% had experienced at least one painful sunburn during the previous summer. The mean daily personal ultraviolet exposure per day, the minimal erythema dose, and the standard erythema dose, in J/m2, were 634.7 [standard deviation (SD): 356.2], 2.5 (SD: 1.4) and 6.35 (SD: 3.6), respectively. Conclusion: Beach lifeguards receive very high doses of solar radiation during the work day and experience correspondingly high rates of sunburn. Intervention strategies to modify their sun exposure behavior and working environment are necessary to reduce the risk of skin cancer for these workers and to promote early diagnosis of the disease.

Amblyopia resulting from early deprivation of vision or defocus in one eye reflects an imbalance of input from the eyes to the visual cortex. We tested the hypothesis that asynchronous stimulation of the two eyes might induce synaptic plasticity and rebalance input. Experiments on normal adults showed that repetitive brief exposure of grating stimuli, with the onset of each stimulus delayed by 8.3 ms in one eye, results in a shift in perceptual eye dominance. Clinical studies (Clinical trial registration number: ChiCTR2100049130), using popular 3D movies with similar asynchrony between the two eyes (amblyopic eye stimulated first) to treat anisometropic amblyopia, established that just 10.5 h of conditioning over <3 weeks produced improvement that met criteria for successful treatment. The benefits of asynchronous conditioning accumulate over 20–30 45 min sessions, and are maintained for at least 2 years. Finally, we demonstrate that asynchronous binocular treatment alone is more effective than patching only. This novel treatment is popular with children and is some 50 times more efficient than patching alone. [ABSTRACT FROM AUTHOR]

While much has been done to study how cartilage responds to mechanical loading, as well as modelling such responses, arguably less has been accomplished around the mechanics of the cartilage–bone junction. Previously, it has been reported that the presence of bony spicules invading the zone of calcified cartilage, preceded the formation of new subchondral bone and the advancing of the cement line (Thambyah and Broom in Osteoarthr Cartil 17:456–463, 2009). In this study, the morphology and frequency of bone spicules in the cartilage–bone interface of osteochondral beams subjected to three-point bending were modelled, and the results are discussed within the context of biomechanical theories on bone formation. It was found that the stress and strain magnitudes, and their distribution were sensitive to the presence and number of spicules. Spicule numbers and shape were shown to affect the strain energy density (SED) distribution in the areas of the cement line adjacent to spicules. Stresses, strains and SED analyses thus provided evidence that the mechanical environment with the addition of spicules promotes bone formation in the cartilage–bone junction. [ABSTRACT FROM AUTHOR]

In total, 380 km of marine magnetic data were processed and interpreted to reveal the main tectonic elements that control the formation of the lake. Lake İznik, which is an approximately rectangular-shaped active tectonic basin with 32 km length and 12 km width, is located between two segments of the North Anatolian Fault in the northeast Marmara region, Turkey. The purpose of this study is to identify the tectonic elements that played a role in the formation of Lake İznik with the help of new magnetic data and to reveal the tectonic evolution of the region by using other previously collected geophysical data. The Euler deconvolution, tilt angle, analytic signal and source edge detection methods were applied to the total field magnetic data for Lake İznik and its surroundings to determine the boundaries and depths to the source of magnetism. From the structural map obtained as a result of the review of this data, linearity in the magnetic data was detected along the NW–SE direction in the north of Lake İznik, N–S direction in the west and east, and E–W direction in the south. These lineaments were correlated with a limited amount of seismic data obtained from previous studies and were associated with faults. This linearity in NW–SE direction in the north was evaluated as the continuation of the Orhangazi fault and it is thought to play a significant role in the tectonic evolution of Lake İznik. When the results obtained from this study and the paleomagnetic results for the Eocene volcanic rocks in the study area are evaluated together, Lake İznik was connected with Gemlik Bay and the Marmara Sea during the Eocene–Pleistocene and Orhangazi Fault disconnected Lake İznik from Gemlik Bay in the Pleistocene–Holocene. It was deduced that the lake basin is a pull-apart basin developed up to the present day. [ABSTRACT FROM AUTHOR]

Utilizing multi‐satellite/instrument observations, we investigate the November 20 2003 Superstorm's impacts on the forward fountain, the duskside and dawnside subauroral flows, and the chemical makeup of the ionospheric plasma. New results show that the nightside forward fountain became active before local midnight and soon after the interplanetary magnetic field (IMF) turned southward at ∼12 UT and remained active for the rest of 20 November and early 21 November. The fountain‐related strong equatorial upward E × B drift lifted up the F2 layer above ∼391 km altitude creating low plasma densities at equatorial and low latitudes. In both hemispheres, the large convection and subauroral electric (E) fields drove plasmaspheric erosions eroding the mid‐ and high‐latitude ionosphere poleward of the plasmapause. On the duskside and dawnside, the subauroral E field drove the Subauroral Polarization Streams (SAPS) in the sunward direction. As our southern cases show, the SAPS E field changed the ionospheric plasma's chemical makeup by locally enhancing the NO+ content and thus decreasing the O/N2 content associated with depleted plasma densities. We conclude that in the strongly coupled Magnetosphere‐Ionosphere‐Thermosphere system, the plasmaspheric erosion had a primary role in depleting the ionospheric plasma. Furthermore, the solar wind pressure disturbances during the long‐lasting southward IMF orientation led to the development of conjugate duskside and dawnside sunward SAPS flows, and SAPS flows contributed to the ionospheric plasma's depletion by increasing the NO+ content as our southern cases show. For the first time, correlated multi‐satellite observations show the dawnside sunward SAPS flows in latitudes and in longitudes. Key Points: The fountain became activated before local midnight at ∼12 UT when interplanetary magnetic field (IMF) turned southward leading to F2 layer uplift (>391 km)Strong convection E field and subauroral polarization streams (SAPS) E field drove plasmaspheric erosions eroding the mid/high‐latitude regionsAt IMF BZ < 0, sunward SAPS flows developed on the dawnside and locally enhanced the NO+ content leading to low Ni and O/N2 [ABSTRACT FROM AUTHOR]

This work conducts a focused study of subauroral ion‐neutral coupling processes and midlatitude ionospheric/thermospheric responses in North America during a minor but quite geo‐effective storm on September 27–28, 2019 under deep solar minimum conditions. Several prominent storm‐time disturbances and associated electrodynamics/dynamics were identified and comprehensively analyzed using Millstone Hill and Poker Flat incoherent scatter radar measurements, Fabry‐Perot interferometer data, total electron content data from Global Navigation Satellite System observations, and thermospheric composition O/N2 data from the Global‐scale Observations of Limb and Disk mission. Despite solar minimum conditions, this minor storm produced several prominent dynamic features, in particular (a) Intense subauroral polarization stream (SAPS) of 1,000 m/s, overlapping with a deepened main trough structure. (b) An enhanced westward wind of 230 m/s and a significant poleward wind surge of 85 m/s occurred in the post‐SAPS period. (c) Large‐scale traveling ionospheric disturbances (TIDs) were generated and propagated equatorward across mid‐latitudes in the storm main phase. TID characteristics were significantly affected by SAPS, evolving into divergent propagation patterns. (d) SAPS was situated on the poleward edge of a considerable storm‐enhanced density structure. (e) The midlatitude ionosphere and thermosphere exhibited a prolonged positive storm effect in the main phase and beginning of recovery phase, with 5–10 TECU increase and 10%–30% O/N2 enhancement for 12 h. This was followed by a considerable negative storm effect with 5–10 TECU and 20%–40% O/N2 decrease. Results show that minor storm intervals can produce substantial mid‐latitude ionospheric and thermospheric dynamics in low solar flux conditions. Key Points: A minor but geo‐effective storm at deep solar minimum produced intense subauroral polarization stream (SAPS), considerable Storm‐enhanced density structure, and subauroral large‐scale traveling ionospheric disturbancesStrong westward wind enhancement of 230 m/s and large poleward wind surge of 85 m/s occurred in the post‐SAPS intervalMidlatitude total electron content and O/N2 simultaneously showed large storm‐time dynamic features, with a prolonged enhancement followed by a large reduction [ABSTRACT FROM AUTHOR]

In the last decades the necessity of implant devices is continuously increasing. The researchers have thus focused their attentions on the development of new biocompatible materials, in particular polymers. Among them, polyetheretherketone (PEEK) has gained wide interest in loadbearing applications such as spinal cages due to its yielding behavior and its superior corrosion resistance. Since such applications are characterized by notches and other stress concentrators weakening the implant resistance, a design tool for assessing their tensile and fatigue behavior, in the presence of such discontinuities, is highly claimed. To this aim, tensile and fatigue data available in literature related to neat and differently notched PEEK samples, experimentally tested in a phosphate-buffered saline (PBS) at 37 �C have been analyzed using the strain energy density (SED) approach. The method is shown to provide accurate results regardless of the different notch geometries, both in terms of tensile and fatigue behavior. Concerning the former, the tensile strength was in fact estimated with an error lower than �10%, whereas for the latter the SED approach was able to summarize the experimental fatigue data in a single narrow scatter band, independently from the notch geometry

The year 1959 is the first twinning between French Communist municipalities and East German cities under the auspices of the World Federation of Twin Cities. The Franco-German Exchanges (EFA) were created in 1958. The twinnings with the GDR and the EFA are controlled by the French Communist Party. The testimonies of French visitors to the GDR reflect very different impressions, from total seduction to rejection. East Germany tries to export until the disappearance in 1990 an image of socialist Bismarckism or Red Prussia: socialist and bourgeois ,democratic and authoritarian, pacifist and militarist against the so-called West German fascism.

During the geomagnetic storm on September 8–9, 2017, shoulder‐like structures were persistently captured in the lower‐mid latitudes at multiple local times, by Swarm and DMSP satellite observations. A more telling terminology of such shoulder‐like structure called strip‐like bulge is proposed in this study, due to its global presence that spanning over 150° in longitude but only over 1°–5° in latitude. The strip‐like bulges can be categorized into sharp and blunt types depending on the sharpness of the density peaks. The blunt type was short‐lived and appeared earlier than the sharp type in the afternoon‐sunset sector. The sharp type was long‐lived and appeared at all the observed local times. Both two types of strip‐like bulges were dominated by the ion composition of the H+/He+, rather than O+. This is the first evidence that the plasmaspheric particles are involved in forming the ionospheric structure at such low latitude. Moreover, the equatorward movement of the bulges shared the same trends with the earthward movement of the plasmapause. These two types of strip‐like bulges showed different longitudinal dependencies controlled by the magnetic declination. We suggest that the combined effects from the plasmaspheric downwelling and disturbance neutral wind were responsible for the appearance of the strip‐like bulges. Plain Language Summary: In the lower‐mid latitude ionosphere, shoulder‐like plasma density structures are occasionally snapshotted by satellite passes or regional TEC maps during geomagnetic storms. Such ionospheric structures can cause positioning errors for GNSS applications. Previous fragmentary investigations recognize shoulder‐like structures mainly as a regional phenomenon. This study portrays a new global picture of a shoulder‐like structure and finds it more suitable to be termed as strip‐like bulges. The zonal extent of the bulge is beyond 150° in longitude. Some distinctive occurrence features are further revealed, implying the combined formation mechanisms involving plasmaspheric downwelling and disturbed neutral winds. Key Points: Strip‐like plasma density bulges with wide zonal extent exist in lower‐mid latitudes ionosphere during the storm investigatedDominance of H+/He+ indicates that plasmaspheric particles were involved in forming the bulges at such low latitudeDistinctive longitudinal dependences of the bulges on the magnetic declination suggest the effects of neutral winds [ABSTRACT FROM AUTHOR]

Excessive exposure to ultraviolet (UV) radiation from the sun in summer can cause skin cancer and in Britain there are around 1500 new cases of non-melanoma skin cancer (NMSC) each year, caused by exposure to solar UV at work. Little is known about the magnitude of UV exposure amongst outdoor construction workers in Britain, although this is one of the main groups at risk. The aim of this paper is to summarise measurements of erythema-weighted UVB radiation amongst construction workers in Scotland and the Southeast of England and interpret the data in terms of the risk of NMSC. The measurements were made as part of an intervention study using short mobile phone text messages to alter worker behaviour to either reduce UV exposure in summer or increase serum vitamin D in winter; the intervention is only briefly reported here. Data were collected from 67 workers from 9 worksites, of whom 41 provided measures of UV exposure for 758 working days. Daily exposure ranged from 0 to 13.47 standard erythema dose (SED), with the mean exposure for outdoor workers being 2.0 SED and the corresponding value for indoor workers being 0.7 SED. These data were obtained from a sensor located on the back of the workers hard hat; others have measured exposure on the wrist or upper arm and these locations probably, on average, have higher levels of UV exposure. It is likely that an outdoor construction worker in Britain could accumulate sufficient solar UV exposure over 30–40 years of work to more than double their risk of NMSC. We argue that employers in Britain should take a more proactive approach to manage sun safety and they should take responsibility for skin health surveillance for their workers.

L’accueil d’étudiants étrangers et le sport de haut-niveau étaient vus par le régime est-allemand avant tout comme un outil de promotion internationale et comme un moyen de renforcer un certain soft power. En cela, ils ont fait l’objet d’une instrumentalisation permanente par les instances du SED. Cet article se propose d’étudier, à travers l’exemple de la Deutsche Hochschule für Körperkultur, une académie pour le sport située à Leipzig, les modalités de la mise en place de cette politique destinée principalement aux ressortissants africains, asiatiques et latino-américains, ainsi que les raisons de son échec.

Background: Adipsic diabetes insipidus is a rare condition secondary to injury to osmoreceptors in the anterior hypothalamic area. Only two cases have been published secondary to pituitary tumor surgery. Case report: A 43-year-old man, postoperative of a non-functioning pituitary macroadenoma invading the third ventricle and compressing the hypothalamus. Reoperated for headache and rhinorrhachia, developing diabetes insipidus in the postoperative period was discharged with 20 µg/day nasal desmopressin. He came again due to sensorial disorder and hypernatremia, managing to control with intravenous hydration and desmopressin. It presents with recurrence of hypernatremia every time intravenous hydration is suspended and taken orally. With high sodium levels, there is an absence of thirst. A diagnosis of adipsic diabetes insipidus is made, indicating supervised administration of water orally with favorable evolution. Conclusions: Adipsic diabetes insipidus is a rare variant of central diabetes insipidus caused by damage to osmoreceptors in the hypothalamus. It manifests with absence of perception of thirst, hypernatremia and polyuria. Its management is complex and requires strict control of the water balance and adherence to treatment.

The three‐dimensional computerized ionospheric tomography (3DCIT) technique is used to reconstruct the spatial distribution of storm‐enhanced density (SED) based on the global positioning system total electron content measurements over the North American area during the 17 March 2013 storm. The reconstruction results are carefully validated with observations from three ionosonde stations, the constellation observing system for meteorology, ionosphere, and climate (COSMIC) radio occultations, and the Millstone Hill incoherent scatter radar. The electron density profiles from the 3DCIT reconstruction show a good agreement with the ionosonde and COSMIC electron density profiles. The 3DCIT‐derived electron density difference between the storm day of 17 March and the quiet day of 16 March also captures the similar SED plume signature that was observed by the Millstone Hill incoherent scatter radar. The 3DCIT reconstruction allows us for the first time to unveil the 3‐D configuration of the SED plume and its spatiotemporal evolution. It was found that the SED plume first appeared around 400 km and then expanded downward to ~300 km as well as upward to ~500 km over the course of a 3‐hr period from 19 to 22 UT on 17 March. Our study also showed that the density enhancement within the SED plume occurred mostly above the storm time F layer peak height. Key Points: Spatiotemporal evolution of SED plume during geomagnetic storm is reconstructed using 3DCIT techniqueSED plume first appeared around 400‐km altitude and then expanded down to ~300 kmSED plume occurred mostly above the storm time F layer peak height [ABSTRACT FROM AUTHOR]

Saxon Switzerland (Sächsische Schweiz), a region close to the city of Dresden on the river Elbe, is in fact a small mountain range with steep rocks. Even in the nineteenth century, people started climbing the sandstone and developed a proud tradition of strict ethical rules. The use of ladders or any other devices was not allowed. Organized in small clubs, the climbers developed their own identity with a strong feeling of independence. After World War II however, the climbers were forced to join the new socialist sports organizations. The communist functionaries tried to re-define climbing as a conventional sport, but the climbers continued to dream of liberty, friendship, nature and adventure. There was thus considerable friction between the German Democratic Republic officials and the climbers. Climbing became a way of escaping from the socialist society. With the help of different sources, such as interviews with contemporary witnesses, magazine articles and summit registers, this conflict is described and analyzed in the present paper.

Objective: to assess the prevalence, intensity and discomfort of the thirst of the orthopedic surgical patient and the correlations with the demographic and clinical-surgical variables. Method: cross-sectional, quantitative and analytical study with 78 patients in the Post-Anesthetic Recovery Room of a teaching hospital. Results: eight patients (10.3%) reported thirst spontaneously. Its mean intensity was 4.8, and the discomfort, 5.0. The attribute dry mouth was the most prevalent, followed by desire to drink water and dried lips. Intensity correlated significantly with discomfort of thirst in the group of patients from 21 to 40 years. There was a relationship of prevalence between presence of thirst and all the attributes of the Perioperative Thirst Discomfort Scale, with the exception of the attribute bad taste in the mouth. Conclusion: the thirst of the orthopedic surgical patient is prevalent in the postoperative period, with moderate intensity, but considerably uncomfortable. [ABSTRACT FROM AUTHOR]
