Blue whiting Micromesistius poutassou diel feeding behaviour in the Irminger Sea
Authors: Post S , Jónasdóttir SH , Andreasen H , Ólafsdóttir AH , Jansen T
Published: October 2021

With warming ocean temperatures, the abundance of blue whiting Micromesistius poutassou is increasing in the waters around Greenland. However, in this region, knowledge about the species’ trophic role in the ecosystem is scarce. Consequently, we investigated the diet composition and diel feeding behaviour of blue whiting in the north-eastern part of the Irminger Sea in Greenland waters by analysing their stomach contents and the vertical position/movements of their prey from zooplankton samples and hydroacoustic measurements. We collected the data during a designated experimental survey in July 2016 with repeated sampling at the same location. Results from the stomachs of 624 blue whiting individuals ranging from 22-39 cm long (total length) showed that the highest food intake took place from noon until late evening, with minimum feeding occurring in the morning. The most essential prey groups consisted of euphausiids, copepods, amphipods and fish, in that respective order. Regarding copepod prey, blue whiting had a strong affinity for Calanus hyperboreus and Paraeuchaeta spp. and showed potential for local depletion of these large copepods. On the other hand, the more abundant but smaller C. finmarchicus was almost absent in the fish stomachs, in contrast to findings in other regions. This new understanding provides an early indication of some of the emerging trophodynamics in the Irminger Sea and similar subarctic zooplankton communities with increasing numbers of blue whiting. Our results confirm the importance of accounting for diel and size-specific differences in blue whiting feeding when studying various aspects of its food intake.
Testing the critical size at settlement hypothesis for two species of coral reef fish
Authors: Kingsford MJ , Krunes EA , Hall AE
Published: October 2021

The critical size hypothesis states that pelagic larvae (vertebrate or invertebrate) must reach a critical size to begin metamorphosis and settle to their suitable reef habitat; however, there have been few critical tests of its broader validity. If there were a narrower range of ages at settlement relative to size, then the data would conform to a critical age hypothesis. It would also be predicted that size or age would be truncated respectively at the lower limit for each hypothesis. These hypotheses were tested for 2 species of coral reef fish from the Great Barrier Reef. Variation in age at settlement forPomacentrus coelestiswas greater than that of size at settlement for fish collected in waters of different temperatures, and the size distribution was truncated at a size of ~9.3 mm; accordingly, we accepted the critical size at settlement hypothesis for this species. In contrast,Scolopsis bilineatusmet one criterion to reject the critical size hypothesis, based on variation, but truncation in size was found. Variation in age aligned with a critical age at settlement hypothesis. There was a variable relationship between age at settlement and size for both species. Strong evidence is provided that growing fast in the plankton and settling quickly may be advantageous for fish. For both species, settlers with a short planktonic larval duration, and sometimes small size at settlement, had grown faster in the plankton and may have experienced better conditions. Differences in pre-settlement growth are likely to affect the maximum size at which fish can settle and post-settlement survivorship.

Published: October 2021

With coastal wader populations exhibiting long-term declines globally, understanding how they respond to changes in their preferred prey is important for future predictions, especially given the potential for warming seas to affect invertebrate populations. The cockleCerastoderma edulepopulation in the Burry Inlet Special Protection Area (SPA) in south Wales, UK, declined from 1997-2004 before an abrupt ‘crash’ in stocks between 2004 and 2010. While there has been some recovery since, stocks of larger cockles are still very low. Using survey data from the UK Wetland Bird Survey and analyses of apparent survival and biometrics from ringing, we investigated how the Burry Inlet SPA’s wintering Eurasian oystercatcherHaematopus ostraleguspopulation responded to this crash. Our analysis showed that both body condition and apparent survival of wintering adult oystercatchers were reduced in the years following the cockle crash but both recovered. The number of birds using the Burry Inlet SPA decreased through the course of the cockle stock decline whilst numbers of birds in the adjacent Carmarthen Bay increased, indicating the importance of adjacent sites for buffering the effects of such changes, i.e. protected secondary habitats can be a vital component of a resilient site network. Our findings are useful in understanding how a predator copes with a serious decline in its preferred food stocks. This study has wide applicability in planning the management of coastal wetlands and shellfisheries as well as the design of resilient protected area networks in the light of environmental change.

Published: October 2021

The use of several simultaneously operating sources in seismic operations allows one to obtain large amounts of data per unit of time than for classical works with a single source, and also to improve the seismic data recording system. Depending on the type of seismic source used (vibrating or pulsed), different methods of signal separation are used. When working with vibroseismic method, separation of signals becomes possible at the stage of correlative processing of vibrograms. In this paper, we demonstrate methods for constructing noncorrelating signals for use in vibroseis survey (with an example of using such signals on synthetic data) and hyperbolic median filtering to minimize correlation and incoherent noise.

Authors: Pozdniakov S. P. , Grinevsky S. O. , Dediulina E. A. , Samartsev V. N.
Published: October 2021

The analysis of the connection of groundwater recharge in the basin of a small river with the current and expected climatic changes in the European territory of Russia is carried out using the catchment basin of Zhizdra river Kaluga region as an example. The analysis was based on the modeling of the processes of transformation of moisture on the earth surface and moisture transfer in the aeration zone. The results of global climate predictions for five models of the general circulation of the atmosphere and ocean (GCM) from the CMI5 family were applied for the forecast in the second half of the 21st century using the LARSWG5 forecast weather conditions generator. The simulation results show that despite the fact that all the GCM used predict a warming in the region at 2–6 ᵒC, the difference in the predicted recharge is still significantly large, which is associated with the difference in the predicted dryness index.

Authors: Lebedev A. L. , Avilina I. V.
Published: October 2021

Experimental study of kinetics of dissolution of hypso anhydrites at 25 ᵒC made it possible to formulate model of the process in the form of a balance equation for the kinetics of dissolution of gypsum, anhydrite (first and second orders, respectively) and kinetics of precipitation of gypsum (second order). The processing of the experimental data were carried out on the basis of the solution of the Riccati equation. When taking into account the common-ion effect on the solubility of gypsum and anhydrite, the calculated values turned out to be more comparable with the experimental ones.

Remote sensing as a method of predicting PGM mineralization based on the results of the study of the Eastern Sector Bushveld complex
Authors: Shemyakinа E. M.
Published: October 2021

In this paper, a study of the differentiated Bushveld complex (South Africa) is carried out on the basis of remote cosmic and gravimagnetic methods. The article shows the possibility of using Landsat 7 ETM+ multi-zone space imagery and brightness characteristics to predict platinum mineralization in new promising areas. Analysis of the values of the gravitational field showed that in the area under study, platinum mineralization is concentrated in a fairly narrow range of values, which makes it possible to use this data as a search feature. The main conclusions have been formulated and the possibilities of the Landsat 7 ETM + multi-zone space survey to forecast platinum mineralization in new promising areas have been clearly demonstrated. The conducted studies prove the efficiency of the integration of remote (space and geophysical) to improve the approach to prospecting for platinum-coppernickel mineralization.

Published: October 2021

Replenishment of oil reserves requires searching, exploration and production of new unconventional objects. Among these objects is Domanik formation, which is widespread in the Volga-Ural basin. The Domanic high-carbon formation is presented by thin-layered carbonate-siliceous rocks with a high content of organic matter, capable of both producing hydrocarbons with its own oil and gas potential, and concentraring them in reservoirs [Stupakova et al., 2017]. Study of lithological composition of rocks help to obtain information about the nature of hydrocarbon accumulations and understand possibilities of estracting hydrocarbon of them. The lithological and geochemical characteristics of rocks are an integral part of the study such types of deposits.

Published: October 2021

Structural-geomorphological analysis of the modern relief allowed us to reveal Western Taimyr newest structure features and to show the significance of the structural forms shear horizontal displacements, as well as the manifestation of relief in some areas of previously formed thrusts. Since the Oligocene, neotectonic development of the Arctic was determined by Eurasian basin opening. This causes the activation of the North-Eastern faults in the region, which have the same stretch as the transform faults of Gakkel ridge spreading zone, which confirms the active development of this region at the present stage.

Published: October 2021

The geological structure of two freshwater lakes (the Verkhneye and the Vodoprovodnoye) located near the White sea biological Station of the Moscow State University (the Kandalaksha Bay of the White sea) is considered for the first time according to the GPR data. The morphology of the top of the Archean basement, the structure of the Quaternary sedimentary cover and bottom relief were studied. Shallow marine sediments overlying the rocks of the Archean and a sequence of lacustrine-marsh sediments were identified using the drilling data in the Quaternary cover. Structural schemes were constructed for the main reflecting horizons, while isopach schemes were generated on the basis of the main sequences. The values of electrical resistivity and absorption coefficient are calculated and the possibilities of their use for the delineation of GPR facies are considered.
Sensitivity of recharge estimation to the pore connectivity parameter of vadose zone rocks
Authors: Dedulina E. A. , Vasilevskiy P. Yu. , Pozdniakov S. P.
Published: October 2021

Information on recharge value is necessary for solving different classes of hydrogeological problems. One of the methods of recharge estimation is simulation of flow in vadose zone. Soil hydraulic parameters are used to estimate recharge by flow in vadose zone. One of the hydraulic parameters is the pore connectivity parameter l. The sensitivity of estimated recharge to the value of pore connectivity parameter, especially under humid climate conditions, is studied insufficiently. In present study, the experimental values of soil hydraulic parameters of samples from two different sites with various landscape conditions and vadose zone structure (forest landscape on sand and field landscape on loam) were used to estimate recharge.Recharge estimation was also carried for the value of l=0,5 and for reported values of l parameter for certain type of sediment. Analysis of calculation results demonstrated that using fixed value of l=0,5 leads to significant overestimation of calculated recharge both for forest and filed landscapes, which emphasizes the importance of experimental definitions of soil hydraulic parameters for recharge estimation. The analysis of the water balance components showed that the increase of estimated recharge with enhancement of l value is mainly associatedwith the decrease of evaporation from the upper soil layer.
Possibility of high-grade formation in mechanical sedimentation
Authors: Mamedov V. I. , Chausov A. A. , Makarova M. A.
Published: October 2021

To assess the fundamental possibility of the formation of deposits of high-quality bauxites by mechanogenic sedimentary methods, continental deposits in the extreme members of their facies series were studied: eluvial deposits on the surface of the bovaly, representing the region of mobilization of matter; alluvial deposits that underwent transfer and the most significant sorting in continental conditions. It is shown that these deposits do not produce high-quality bauxite deposits, even under uniquely favorable conditions, and the mechanogenic-sedimentary process does not provide the conditions for the spatial separation of aluminum with iron and silica, without which high-quality bauxite deposits cannot be formed.

Published: October 2021

In the section of the eastern Black Sea basin and the Caucasus continental slope, according to 3D seismic data, unique objects were first discovered and described — vertical failure in the Upper Cretaceous — Lower Miocene deposits. An interesting feature of these structures is a close to isometric shape in plan. About 40 objects have been identified on an area of more than 1000 m2. «Bulls-eye» («multiphase») paleo-pockmarks [Andresen, Huuse, 2011], as well as karst collapse [Zuo et al., 2009] are proposed as world analogues with a similar wave pattern on seismic data. The corresponding genesis models are considered, but none of the theories allows drawing a conclusion. The discovered objects are unique and require further investigation.

Published: October 2021

Geochemical studies of sarmatian clays and silts of the Kerch Strait and the Taman Peninsula to determine the paleogeographic features of their formation were researched for the first time. Proxies for paleosalinity and paleobatimetry were built using geochemical data to specify previous reconstructions. Two regressive (early Sarmatian; from the middle of the Late Sarmatian) and two transgressive (middle and early Late Sarmatian; late Late Sarmatian — early Meotian) stages in the development of the study area were distinguished. Data on salinity in ppm were obtained. The effectiveness of the used methods of interpreting geochemical data in paleogeographic reconstructions, which can subsequently be successfully applied to deposits deprived of fossil remains or characterized by a weak indicator function of the species of fauna and flora, is proved.
Secondary dolomitization as a factor determining the reservoir properties of the Lower Devonian deposits in Eastern edge of the Khoreyver depression (Timan-Pechora basin)
Authors: Zhemchugova V. A. , Maslova E. E.
Published: October 2021

The Lower Devonian deposits were characterized in terms of their composition, texture and secondary transformations, the distribution of various types of pore space was analyzed and several types of dolomite textures were identified. The analysis showed that permeability, solubility and primary texture of carbonate rock or sediment, as well as temperature, volume and exposure time of dolomitizing fluids are key factors for dolomitization and depending on these factors dolomitization can lead to not only increase but also decrease of porosity.

The Muqaddam Represented in the pre-Mongol Persian Documents from Ghur
Authors: Husseini Said Reza
Published: October 2021

This paper addresses the Muqaddam, or the village headman, the relevant fiscal department, and the process of tax collection as represented in pre-Mongol Persian documents found recently in the Ghur region in present day Afghanistan. It argues that “Muqaddam” was the title used for a village notable associated with the fiscal department called the Diwān al-Ikhtiyārī. The Muqaddam collected the ʿushr, or the state's shares of harvests as prescribed under Islamic law. The tax is collected only in the presence of the Muʿtamid, who is the Diwān's trusted agent. Tax collection followed the Diwān's issuance of an edict termed ḥukm-i tafṣīl, which detailed the instructions given to the Muqaddam.

The analysis in this article highlights the Ghurid aspect of the Muqaddam's role, which was previously unknown. This is due in part to the scarcity of primary sources about his roles; in part because the Muqaddam mentioned in the medieval north Indian Persian literature overshadowed discussion on the Muqaddam. By analysing the Ghurid documents, this paper thus argues “Muqaddam” was a term specifically used in the Ghur region in a particular agricultural context.

Numerical validation of an analytical seal flutter model
Authors: Greco Michele , Corral Roque
Published: October 2021

An analytical model to describe the flutter onset of straight-through labyrinth seals has been numerically validated using a frequency domain linearized Navier-Stokes solver. A comprehensive set of simulations has been conducted to assess the stability criterion of the analytical model originally derived by Corral and Vega (2018), “Conceptual Flutter Analysis of Labyrinth Seals Using Analytical Models - Part I: Theoretical Support,” ASME J. Turbomach., 140 (12), pp. 121006. The accuracy of the model has been assessed by using a simplified geometry consisting of a two-fin straight-through labyrinth seal with identical gaps. The effective gaps and the kinetic energy carried over are retained and their effects on stability are evaluated. It turns out that is important to inform the model with the correct values of both parameters to allow a proper comparison with the numerical simulations. Moreover, the non-isentropic perturbations included in the formulations are observed in the simulations at relatively low frequencies whose characteristic time is of the same order as the discharge time of the seal. This effect is responsible for the bending of the stability limit in the 0th ND stability map obtained both in the model and the simulations. It turns out that the analytical model can predict accurately the stability of the seal in a wide range of pressure ratios, vibration mode-shapes, and frequencies provided that this is informed with the fluid dynamic gaps and the energy carried over to the downstream fin from a steady RANS simulation. The numerical calculations show for the first time that the model can be used to predict accurately not only the trends of the work-per-cycle of the seal but also quantitative results.
Sparse complete sets for coNP: Solution of the P versus NP problem
Authors: Vega Frank
Published: October 2021

P versus NP is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is P equal to NP? A precise statement of the P versus NP problem was introduced independently by Stephen Cook and Leonid Levin. Since that date, all efforts to find a proof for this problem have failed. Another major complexity class is coNP. Whether NP = coNP is another fundamental question that it is as important as it is unresolved. In 1979, Fortune showed that if any sparse language is coNP-complete, then P = NP. We prove there is a possible sparse language in coNP-complete. In this way, we demonstrate the complexity class P is equal to NP.
Frustration, Examination, Appreciation: An Autoethnography of a Psychotherapist’s Work with a Challenging Patient
Authors: Tyson June
Published: October 2021

The work of a psychotherapist can be rewarding and very challenging. It can be frustrating when patients are suffering and there are no words to alleviate their pain, or when they begin to take their anger out on you as a therapist. The work of a psychotherapist can be a personal beneficial experience as one examines how one is affected as a professional because of a seemingly difficult and challenging patient. The work of psychotherapy can also bring about a sense of appreciation as psychotherapists learn to appreciate their own delicate individual growth because of a challenging patient.
Infrapatellar Branch of the Saphenous Nerve Injury: Implications for the Physical Therapist
Authors: Thompson Irwin S.
Published: October 2021

Injury to the infrapatellar branch of the saphenous nerve (IBSN) is an underreported condition which has important implications for the physical therapist. Due to its location, the IBSN is especially vulnerable to damage following surgery, but it may also be injured through trauma or unknown causes. Patients with suspected IBSN injury may present with a variety of symptoms, including pain along the nerve distribution, paresthesia, hypoesthesia, anesthesia, and impaired functional activities and mobility. As the presence of IBSN injury may not be readily apparent, it is incumbent upon the physical therapist to recognize the signs and symptoms associated with this condition, and to administer a detailed clinical examination. Clinical evaluation can be difficult, as IBSN injury mimics many other conditions of the knee. Additionally, saphenous nerve anatomy exhibits wide variance, even within individuals, making diagnosis challenging. Upon suspicion of IBSN injury, the physical therapist should refer the patient for a comprehensive medical exam, which may include nerve blocks, nerve conduction studies, MRI, CT scan, or exploratory surgery. Most patients respond well to surgical intervention, including neurolysis or neurectomy, though conservative treatment options exist. These include nerve blocks or pharmacologic interventions. Physical therapy treatment is not well reported and may only be appropriate for specific etiologies of injury.

JPZISNU (Jaringan Pengumpul Zakat, Infaq, da Shadaqah Nahdlatul Ulama) di ranting Sedayu, Kecamatan Turen Kabupaten Malang, merupakan suatu organisasi di bawah pengawasan BAZNAS (Badan Amil Zakat Nasional) berperan sebagai pengumpul zakat masyarakat di tingkat ranting (desa/kelurahan). Sifat keanggotaan JPZISNU adalah secara sukarela. JPZISNU memiliki kewajiban utama melaporkan data keuangan yang dikelola, kegiatan yang dilakukan, serta ianah syariah lainnya. Dengan demikian, penggunaan program berbantuan komputer, khususnya Microsoft Excel, akan sangat membantu dalam penyusunan laporan ke badan pusat.

Pada kenyataannya, pengurus JPZISNU Ranting Sedayu saat ini hanya terbatas dua orang yang mampu mengoperasikan Microsoft Excel untuk menyusun laporan keuangan. Didasari kenyataan itulah maka gagasan untuk melaksanakan kegiatan PKM (Pengabdian Kepada Masyarakat) berupa Pelatihan Program Komputer Microsoft Excel diberikan kepada pengurus JPZISNU. Tujuan PKM ini adalah memperkenalkan dan memberikan pelatihan komputer program Microsoft Excel kepada pengurus JPZISNU ranting Sedayu. Dengan dilakukannya pelatihan Microsoft Excel, sangat membantu Pengurus JPZISNU dalam mengelola pencatatan keluar masuknya uang zakat, infaq, dan shadaqah dalam organisasi serta dapat membantu memudahkan penyusunan laporan pertanggungjawaban organisasi ke BAZNAS pusat.

Potensi sumber alam di lingkungan sekitar berupa ketersediaan sumber makanan kambing yang melimpah RT04/RW2, Desa Pakis, Kecamatan Durenan, Kabupaten Trenggalek, pada tahun 2017 telah mulai dimanfaatkan oleh mitra untuk usaha pemeliharaan kambing sebagai upaya dalam meningkatkan kemampuan ekonomi rumah tangga. Dari proses pemeliharaan yang baik dan ketersediaan sumber makanan yang melimpah, sampai dengan sekarang sudah berhasil dibudidayakan 12 ekor kambing dari awal pembudidayaan sejumlah 2 kambing calon indukan. Dalam perjalanannya, dalam menekuni usaha ini, ditemui kendala utama yang menghambat kemajuan dari usaha ini, yaitu kendala kurang idealnya kandang kambing yang ada untuk dapat mendukung keberhasilan usaha tsb. Konstruksi, sanitasi, dan luasan kandang yang ada belum cukup ideal sebagaimana telah diatur atau dipandu dalam suatu Peraturan Menteri Pertanian yang ada. Diyakini bahwa apabila kendala-kendala ini dapat diselesaikan maka akan dapat meningkatkan keberhasilan usaha ini, bahkan berpotensi untuk bisa menjadi model usaha pemeliharan kambing sekala kecil rumah tangga yang dapat dijadikan rujukan rujukan bagi calon-calon pemula usaha pemeliharaan kambing. Sebagai solusinya kepada mitra diberikan pelatihan untuk merancang kandang kambing yang ideal dengan mengacu kepada Peraturan Menteri Pertanian yang ada yang selanjutnya kepada mitra dilatih untuk membuat kandang kambing yang telah dirancang.

Objective: To evaluate the use of tourniquet and forceps to reduce bleeding during surgical treatment of severe placenta accreta spectrum (placenta increta and placenta percreta).

Methods: A tourniquet was used in the lower part of the uterus during surgical treatment of severe placenta accreta spectrum. Severe placenta accreta spectrum was classified into two types according to the relative position of the placenta and tourniquet during surgery: upper-tourniquet type, in which the entire placenta was above the tourniquet, and lower-tourniquet type, in which part or all of the placenta was below the tourniquet. The surgical effects of the two types were retrospectively compared. We then added forceps to the lower-tourniquet group to achieve further bleeding reduction. Finally, the surgical effects of the two types were prospectively compared.

Results: During the retrospective phase, patients in the lower-tourniquet group experienced more severe symptoms than did patients in the upper-tourniquet group, based on mean intraoperative blood loss (upper-tourniquet group 787.5 ml, lower-tourniquet group 1434.4 ml) intensive care unit admission rate (upper-tourniquet group 1.0%, lower-tourniquet group 33.3%), and length of hospital stay (upper-tourniquet group 10.2d, lower-tourniquet group 12.1d). During the prospective phase, after introduction of the revised surgical method involving forceps (in the lower-tourniquet group), the lower-tourniquet group exhibited improvements in the above indicators (intraoperative average blood loss 722.9 ml, intensive care unit admission rate 4.3%, hospital stays 9.0d). No increase in the rate of complications was observed.

Conclusion: The relative positions of the placenta and tourniquet may influence the perioperative risk of severe placenta accreta spectrum. The method using a tourniquet (and forceps if necessary) can improve the surgical effect in cases of severe placenta accreta spectrum.

This study aimed to establish and validate the nomograms to predict the mortality risk of patients with coronavirus disease 2019 (COVID-19) using routine clinical indicators. This retrospective study included a development cohort enrolled 2,119 hospitalized patients with COVID-19 and a validation cohort included 1,504 patients with COVID-19. The demographics, clinical manifestations, vital signs, and laboratory tests of the patients at admission and outcome of in-hospital death were recorded. The independent factors associated with death were identified by a forward stepwise multivariate logistic regression analysis and used to construct the two prognostic nomograms. The nomogram 1 was a full model to include nine factors identified in the multivariate logistic regression and nomogram 2 was built by selecting four factors from nine to perform as a reduced model. The nomogram 1 and nomogram 2 showed better performance in discrimination and calibration than the Multilobular infiltration, hypo-Lymphocytosis, Bacterial coinfection, Smoking history, hyper-Tension and Age (MuLBSTA) score in training. In validation, nomogram 1 performed better than nomogram 2 for calibration. We recommend the application of nomogram 1 in general hospitals which provide robust prognostic performance though more cumbersome; nomogram 2 in the out-patient, emergency department, and mobile cabin hospitals, which depend on less laboratory examinations to make the assessment more convenient. Both the nomograms can help the clinicians to identify the patients at risk of death with routine clinical indicators at admission, which may reduce the overall mortality of COVID-19.
