Tectonic stress and the source mechanism of the Imperial Valley, California, earthquake of 1940
Authors: Trifunac M. D. 
Published: September 2021

Abstract
The Imperial Valley earthquake was a multiple sequence (Trifunac and Brune, 1970) with at least four events occurring during the main energy release. These four events, recorded on the strong-motion seismograph in El Centro, located about 10 km NW from the instrumentally determined epicenter, and nine aftershocks recorded in the next 5 min are re-examined in this paper to test an approximate source theory (Brune, 1970). This theory predicts the shape of the body-wave spectra in terms of the seismic moment and stress drop. By fitting theoretical spectra to the spectra calculated from the strong-motion accelerogram, moment and stress drop can be estimated for each of the multiple events. Inasmuch as the average displacements at the fault and the source dimensions can be derived from the known moment and stress drop, the pattern of average displacements along the fault was computed from the instrumental records. A test of the theory, then, consists of comparing the fault displacements derived from seismograms with the fault displacements observed at the surface (Buwalda, unpublished field notes). For the Imperial Valley earthquake, agreement between these two independent methods of measurement is good, suggesting that the above theory is an adequate first approximation for the spectra of body waves. The stress drop variations along the fault, inferred also from the above theory, indicate two areas of major stress concentration located near the northwestern and southeastern ends of the dislocation. The stress drops for various events varied from about ten to several hundred bars.
Seismic effects of the MILROW and CANNIKIN nuclear explosions
Authors: Engdahl E. R. 
Published: September 2021

abstract
Seismic effects of the underground nuclear explosions MILROW (October 1969, about 1 megaton) and CANNIKIN (November 1971, under 5 megatons) were monitored by a network of continuously recording, high-frequency, high-gain seismographs located on Amchitka and nearby islands.
Each explosion was immediately followed by hundreds of small, discrete events (mB &lt; 4), of similar focal mechanism and with a characteristic low-frequency signature, which were apparently related to the deterioration of the explosion cavity. This activity intensified, then terminated within minutes of a large, complex multiple event and concurrent formation of a surface subsided area that signaled complete collapse of the explosion cavity (MILROW, 37 hr; CANNIKIN, 38 hr).
A number of small explosion-stimulated tectonic events, apparently unrelated to the collapse phenomenon, occurred intermittently for several weeks following each explosion—near the explosion cavity and up to 13 km southeast of CANNIKIN ground zero along the Island. These events were confined to the upper crust of the Island, had characteristic high-frequency signatures, and, near the Rifle Range Fault, had focal mechanisms which could be correlated with pre-existing faulting. The evidence points to a short-term interaction of the explosions with local ambient tectonic stresses. Because these stresses are of relatively low level on Amchitka, the observed seismic effects were significantly less extensive and smaller than similar effects reported from high-yield explosions at the Nevada Test Site.
Continuous monitoring of the natural seismicity of the Amchitka region since 1969 has not revealed other evidence for an interaction between either MILROW or CANNIKIN and natural tectonic processes. The structural stability and apparent low level of stress in the upper crust of Amchitka suggest that the Island effectively is seismically decoupled from the active subduction zone below.
The upper mantle beneath the Aleutian Island Arc from pure-path Rayleigh-wave dispersion data
Authors: Jacob K. H. , Hamada K. 
Published: September 2021

abstract
Group velocities of Rayleigh waves recorded at a long-period seismograph station on Amchitka Island were obtained for mixed tectonic paths across the Pacific and the Aleutian Island Arc Ridge. The mixed-path group velocities for periods between 20 and 60 sec were then separated into pure-oceanic and pureridge path group velocities. The group velocities for the pure paths along the Aleutian ridge are on the average 0.36 km/sec lower than those for the purely oceanic paths across the Pacific. Inversion of the pure-ridge group velocities yields almost continental shear velocities in the crust, a very gradual crust-mantle transition at depths between 20 and 40 km, a thin lithospheric lid of uppermost mantle material between 30 and 70 km with relatively low maximum shear velocities approaching 4.4 km/sec, and a very pronounced low-velocity zone at depths below 70 km with an average shear velocity of 4.1 km/sec. The computed shear velocity structure beneath the Aleutian Ridge is compared to models for other tectonically active and stable regions.
Modification of seismograph records for effects of local soil conditions
Authors: Schnabel P. , Seed H. Bolton , Lysmer J. 
Published: September 2021

abstract
A procedure for modifying the time histories of seismic records for the effect of local soil conditions is presented. The method is based on a conventional one-dimensional wave-propagation approach with equivalent linear soil properties, extended to practical use for transient motions through the Fast Fourier technique. The validity of the approach is tested against the motions recorded at four soil sites and one rock site during the 1957 San Francisco earthquake. The good agreement between the computed and recorded values indicates that rock motions can be computed from motions recorded on soil deposits, and that the computed rock motions in turn can be used to predict the motion that would have been recorded under different soil and geological conditions. The method is also used to evaluate the probable rock motions in the vicinity of El Centro in the earthquake of 1940 and the ground surface motions that could have been developed on various soil conditions in the same general area.

Repetition and estrangement
The fixed idea in a tale of I. U. Tarchetti
The article aims to investigate the process of estrangement through the tale La lettera U, by Iginio Ugo Tarchetti. By adopting the point of view of a madman, Tarchetti stages an estrangement that affects the entire discourse of the character. The fixed idea, a symptom of monomania (the psychiatric definition of this type of delirium at the time) gives rise to a narrative device with a strong alienating potential, able to highlight the differences between the notion of Šklovskij's ostranenie and estrangement as presented in fantastic literature.

Estrangement and Out-of-Placeness in the Works of Luigi Gualdo
Characters and places between ideal and reality, cosmopolitanism and uprooting
This paper focuses on the different forms of estrangement and out-of-placeness which can be found in Luigi Gualdo’s works. Gualdo (1844-1898) was a prominent writer whose works are influenced by French realism and Parnasse, Italian scapigliatura and the European decadence and estheticism. Moreover, he lived between France and Italy and he was one of the main passeurs between French and Italian literature of his time. This particular condition of the writer is reflected in his works and in particular in the portraiture of his characters, which are often rootless artists and mundane women with a strong component of cosmopolitism. The aim of this paper is to analyse some of the characteristics and features of Gualdo’s characters according to the parameters of estrangement and out-of-placeness. In particular I will focus on the ambiguous nature of the relation between ideal world and reality, of artistic genius and its place in society and the normal world, as well as on more specific topics related to the subject, such as spleen, places described as theatrical decors, hotel rooms and feminine nomadic attitudes, cosmopolitism as both a challenge and an opportunity for the characters. I will conclude on a specific issue regarding the struggle between the estranged character, time, and aging.

The aimof the work is to generalize the literature data on indolocarbazole derivatives with an antitumor activity.Materials and methods.The objects of the study were the preparations based on indolocarbazole derivatives with the antitumor activity. To search for materials on the problem under study, the following search and information as well as library databases were used: ebibrary, PubMed, CyberLeninka, ResearchGate, the State Register of Medicines, clinical trials registries clinline.ru and clinicaltrials.gov. The search for the following words / phrases was performed: indolocarbazoles, indolocarbazole derivatives, staurosporine, rebeccamycin, staurosporine derivatives. The search was conducted from January 11 until March 1, 2021. The compounds with a biological activity which were undergoing or had undergone preclinical and clinical trials, were taken into account. All the materials from 1977 to January 1, 2021, were taken into account.Results.The materials obtained indicate that indolocarbazole derivatives are promising compounds for the creation of anticancer medicinal preparations due to their properties and peculiarities of the action mechanism. These drugs have a selective action due to the targeted interaction with specific molecular targets: kinases (especially protein kinase C and its isozymes), DNA and DNA topoisomerase. To date, many compounds from the class of indolocarbazoles have been synthesized and investigated. They have shown a high antitumor activity in the treatment of systemic and solid tumors. However, despite this, only one MP based on a staurosporine derivative, registered by the TN of Rydapt® (in the USA and EU countries) and Miticaid® (in the Russian Federation), is approved for use in the clinical practice.Conclusion.Thus, the basic data from scientific publications on promising anticancer medicinal preparations based on compounds from the class of indolocarbazoles, have been summarized. The information is provided, in particular, on their molecular structure, the origin, classification, the main representatives of the class, which are at various stages of the research and are approved for use in the clinic.
The Influence of Soil Conditioning on Soil Infiltration Rate in Urban Facilities
Authors: Nugroho Searphin , Hadi Wahyono 
Published: September 2021

Several attempts have been made to increase the permeable area in the cities, which include the building of green facilities such as parks and urban forests. Since these areas were built with soil compaction, the potential for infiltrating water differs compared with the natural green area. Therefore, this research aims to analyze the influence of soil conditioning on the constant infiltration rate using variables such as soil compaction, texture, and the presence of vegetation cover in urban facilities. The data used were obtained through field infiltration measurement using a single ring infiltrometer. In this research, the analysis carried out includes soil texture, Horton equation, the difference between conditioned soils and control plots, and USDA hydrologic soil classifications. The results showed that all variables (soil compaction, the presence of vegetation cover, and soil texture) have a significant effect on the constant infiltration rate. Based on the soil conditioning, the infiltration rate is increased on the vegetated plots and decreased on the plots with the combination of vegetation and compaction, as well as the compacted plots. Furthermore, the effect of vegetation cover is more significant in silt loam textured soil, while the influence of compaction is more on clay textured soil. The potential constant infiltration rate on the plots of similar characteristics with green urban areas are on K2 and L2 with 2.698 mm/h and 1.525 mm/h, respectively. Therefore, these plots have a moderate runoff potential based on USDA hydrologic soil classification.

Published: September 2021

A study of consumer preferences for dried and half-dried fish products among respondents regularly visiting large retail sites in the city of Murmansk was conducted. It was found that more than two-thirds of respondents prefer to purchase high-quality dried and half-dried fish products; the weight of the purchased package of this product does not have a significant value. Sensory evaluation of extracts of 16 phytoproducts was carried out and the following highest-scoring ones were selected: chamomile flowers; golden mustache; linden flowers and sand immortelle flowers. Experiments of salting Atlantic salmon fillets and cod fillets in a weak saline solution with phytoextract for 12-96 hours were carried out; the ratio of fish, saline solution and aqueous extract of phytoproducts were 1:1:0.01. The most acceptable duration of weak finished salting is established not to be exceeding 48 hours. Experiments on drying the semi-finished product were carried out to establish the quality characteristics and the maximum duration of dehydration of the dried and half-dried fish product. Studies of the dehydrated product carried out every 4 hours by the sensory evaluations, the content and activity of water Aw established the most acceptable drying time, not exceeding 36 hours. Studies of dried fish products were carried out every 20 days according to organoleptic, chemical and microbiological parameters during the 80-day storage period. An acceptable storage period (shelf life) at the temperature of 0 - minus 5 ? of dried and half-dried vacuumed fish has been established to be of two months. Based on the results of the experiments, the technical specifications and technological instructions for the production of a new type of dried and half-dried formed fish with improved properties were developed.

The description of the technological scheme of the granulation site at the Borinsky sugar plant is given, with an analysis of the work of the main types of technological equipment to identify problem areas of production. It is established that the use of such a promising press as the one of the Babbinni company allows you to get pulp with a humidity of 68-76 %. To dry it in a drum dryer to a humidity of 11–13%, 170 m3 of natural gas is consumed per 1 ton of pulp. The technological process of obtaining granulated beet pulp includes pressing the initial beet pulp with an initial humidity of 85–90% to a humidity of 68–76 %; drying the pressed pulp with a heat carrier at a temperature of 110–140 °C for 90–120 minutes to a final humidity of 11–13 %; cleaning pellets from metal-magnetic impurities; granulating the pulp (the diameter of the pellets is 10 mm); cooling pellets to a temperature of 30–35 °C; fractionation of pellets into large and small fractions; weighing and shipping granulated beet pulp to the warehouse of finished products. The technological modes influence analysis of beet pulp pressing, drying and granulating processes at the Borinsky sugar plant showed the need to introduce a second stage of pressing to further reduce the moisture content in the pressed pulp. Obtaining pressed pulp with a lower moisture content will significantly reduce the energy consumption for moisture evaporation in the drum dryer. Reducing the duration of the heat drying process of pressed beet pulp in a drum dryer will significantly increase the nutritional value of the granulated beet pulp produced.

Abstract
Supercontinuum (SC) light source has advanced ultrafast laser spectroscopy in condensed matter science, biology, physics, and chemistry. Compared to the frequently used photonic crystal fibers and bulk materials, femtosecond laser filamentation in gases is damage-immune for supercontinuum generation. A bottleneck problem is the strong jitters from filament induced self-heating at kHz repetition rate level. We demonstrated stable kHz supercontinuum generation directly in air with multiple mJ level pulse energy. This was achieved by applying an external DC electric field to the air plasma filament. Both pointing and intensity jitters of the 1 kHz air filament induced SC light were reduced by more than 2 fold. This offers the opportunity for stable intense SC generation and other laser filament based applications in air.

Abstract
Chemotherapy-induced ovarian damage and fertility loss have negative impacts on the quality of life for female cancer patients worldwide. Thus, we aimed to explore the feasibility and safety of gene therapy for prevention of such damage. First, we validated doxorubicin-induced ovarian damage in human and mouse ovarian tissues and identified two key genes (Sirt1 and Tgfbr2). Next, we generated AdV-Sirt1 and AdV-Tgfbr2 after vectors screening (AdV,AAV and LV) for their ability to transduce mouse ovaries. Finally, we conducted in situ ovarian injection of AdV-Sirt1 and AdV-Tgfbr2 in doxorubicin-treated mice and assessed their ovarian functions and reserves. The interventions dramatically alleviated doxorubicin-induced ovarian damage without apparently influencing the health status of their offspring. Together, our results indicate that AdV-Sirt1 and AdV-Tgfbr2 can serve as effective and safe agents for reducing doxorubicin-induced ovarian damage and also suggest that they may be potentially applicable for post-chemotherapy protection in female cancer patients.

Abstract
Background: Artisanal Mining of Cassiterite at Bisichi (Kara II) and Kuru-Jentar is a very tedious activity that is carried out by artisanal miners. It involves the use of primitive tools like digger, spade, shovel and to mention a few. Most of the artisanal mining activity in the study area is done with no prior knowledge about the geochemical constituent of the mineral deposit in the area but in order to solve the above stated problem, a geochemical analysis was conducted on the obtained samples of cassiterite from the study area and a geologic map of the mining pit was digitized using Ilwis 3.1 academic and Surfer 12. Result: A random sampling method was used to obtain ten (10) samples of cassiterite from the various visited pit at the study area with each weighing 10g. A laboratory analysis was also conducted using X-ray Fluorescence (XRF) analysis which shows that samples from Pit 1 to Pit 5 in the mine site at Kuru-Jentar has 44.45% - 44.9% of Tin (Sn) and 7.86% - 9.00% of Iron (II) oxide (Fe2O3) while samples from Pit 5 to Pit 10 in the mine site at Bisichi (Kara II) has 28.2% - 32.2 % of Tin (Sn) and 15.57% - 16.67% of Iron II oxide (Fe2O3). Conclusively, an understanding of the geochemical constituent of a mineral deposit within a given study area would help increase the knowledge of miners and also attract interested investors.
Droplet lift-off from hydrophobic surfaces from impact with soft-hydrogel spheres
Authors: Rabbi Rafsan , Kiyama Akihito , Allen John , Truscott Tadd 
Published: September 2021

Abstract
Droplet impacts on superhydrophobic surfaces may result in complete bouncing, with the absence of contact hysteresis and viscous dissipation leading the droplet to fully rebound off the surface. This rebound usually happens in the retraction phase, when the droplet retracts back after reaching a maximum spread diameter. Here, we present experimental evidence of a novel bouncing phenomenon where a sessile droplet on a hydrophobic surface bounces off the surface in its spreading phase when a soft deformable hydrogel sphere axisymmetrically impacts the droplet. We term this as 'Lift-Off' and propose a simple force balance based on the deformation characteristics of the hydrogel sphere to explain the out-of-plane jump of the droplet during spreading. We observe three different impact regimes, and propose their dependency on a modified elastic 'Mach' number (Ma*) with (Ma*)=0.2 corresponding to the onset of lift-off. We also report on the unique acoustic signatures of lift-off cases, associated with the capture of air-bubbles through the air-borne retracting droplet rim. Concerning the novel lift-off results, this work may have potential applications for drainage and surface cleaning, non-stick surface coating, industrial mixing and plant disease spreading.

Abstract
The prevalence of the metabolic syndrome (MetS) and its cardiac comorbidities as cardiac hypertrophy (CH) have increased considerably due to the high consumption of carbohydrates, such as sucrose and/or fructose. We compared the effects of sucrose (S), fructose (F) and their combination (S + F) on the development of MetS in weaned male Wistar rats and established the relationship between the consumption of these sugars and the degree of cardiac CH development, oxidative stress (OS) and Calcium/calmodulin-dependent protein kinase type II subunit delta oxidation (ox-CaMKIIδ). 12 weeks after the beginning of treatments with S, F or S + F, arterial pressure (AP) was measured and 8 weeks later (to complete 20 weeks) the animals were sacrificed and blood samples, visceral adipose tissue and hearts were obtained. Biochemical parameters were determined in serum and cardiac tissue to evaluate the development of MetS and OS. To evaluate CH, atrial natriuretic peptide (ANP), CaMKIIδ and ox-CaMKIIδ were determined by western blot and histological studies were performed in cardiac tissue. Our data showed that chronic consumption of S + F exacerbates MetS-induced CH which is related with a higher OS and ox-CaMKIIδ.
