Geochemical characteristics of produced water from coalbed methane wells and its influence on productivity in Laochang Coalfield, China
Authors: Du Mingyang , Wu Caifang , Zhou He , Zhang Shasha , Zhang Erchao 
Published: November 2020

Abstract
The water produced from the coalbed methane (CBM) wells contains abundant geochemical information, which is of great significance in evaluating the productivity of these wells. Based on the data of water produced from five CBM wells, geochemical characteristics of the produced water and its influence on the productivity of the wells are analyzed in Laochang Block. The results show that with the increase in the produced water of the five wells, δD and δ18O show a downward trend in general, reflecting that the influence of coal seams and surrounding rock on the produced water is weak, while the water–rock interaction of the Y-3 and Y-5 wells is more stable than that of the Y-1, Y-2, and Y-4 wells. Combining the water production characteristics of the Y-3 and Y-5 wells with better drainage and recovery effects, it is proposed that 0 ≤ σ
M < 0.3 and 0 ≤ σ
Y < 600 or 0.7 < σ
M < 0.8 and 1,200 < σ
Y < 1,300, and the fluctuation ranges of Ca2+, Mg2+, HCO3
− and SO4
2− can provide a basis for quantitative characterization and evaluation of CBM well production.

Published: November 2020

Abstract
The mechanism of fracture propagation, interaction and coalescence inside rock masses is a highly concerned issue in geotechnical engineering. But as it is difficult to manufacture 3D internal pre-fractures and observe directly the failure evolution process inside real rocks or their opaque similar materials, most previous studies have been limited to 2D conditions. The experiment investigation on 3D rock failure is still in a preliminary stage. In this study, a resin material has been developed by extensive formula tries. It is absolutely transparent and the ratio of tension–compression strength (brittleness value) can be 1/6.6 at −10 to −15℃. It is much more brittle and rock-like than analogous materials used by former scholars. A set of preparation, casting mould, and post-processing technologies were established and specimen-making with multiple pre-fractures is enabled. In the designed scheme, specimens are made with two parallel internal fracture surfaces yet of four different stagger separations. Uniaxial tests were carried out and the stress–strain relationship is analysed. It is shown that the specimen has gone through four stages as the traditional rock test before failure. Many diverse forms of secondary fractures, such as wrapping wing crack, petaloid crack, and giant quasi-wrapping fracture surface, which were not found in 2D conditions have appeared and their evolutions were clearly seen in each stage.
Application of electrical resistivity imaging to detection of hidden geological structures in a single roadway

Published: November 2020

Abstract
Locating concealed geological structures in coal seams on both sides of a coal mine excavation roadway is of vital importance for safe production. Conventional electrical resistivity imaging methods mostly arrange observation systems on the roadway roof and floor, so they are inevitably deficient when it comes to detecting concealed geological structures in coal seams. According to the electric field distribution characteristics of artificial field sources for electrical resistivity imaging methods and utilizing the shielding of current by roadway cavities, this paper proposes the parallel coal seam detection method that arranges observation systems in coal seams on the roadway side to detect concealed geological structures in coal seams. On the basis of introducing the principles of consequent detection methods, this paper investigates the influence of roadway cavities on observation results and offers a method of correcting the influence of roadway cavities. In view of the geoelectric characteristics of typical concealed geological structures in working faces, this paper establishes numerical models to verify the feasibility of the parallel coal seam detection method. As indicated by the calculation results, the consequent pole–dipole (A-MN) observation system is the most ideal in terms of dividing the geoelectric interfaces of concealed geological structures in working faces, and its detection effect is influenced significantly by the coal seam thickness and the electric differences between surrounding rock and anomalous bodies. Coal seam resistivity slightly influences detection of the consequent pole–dipole system. According to practical application effects, the parallel coal seam detection method can solve the problem of detecting concealed geological structures in “single-roadway” working faces.

Abstract
The Cretaceous nonmarine sedimentary strata are widespread in Songliao Basin, Northeast China. As the largest oil producer in China, an abundance of data has been generated by the petroleum industry, including sedimentology, seismology, geochemistry, and geochronology in the Songliao Basin. This article reviews the achievements in China Cretaceous Continental Scientific Drilling SK and presents the new results of the China Continental Geothermal Drilling SR1 in stratigraphy and geophysics. The results allow us to establish the relationships among SK-1, SK-2, and SR1, provide some constrains on the tectonic setting of Songliao Basin, and interpret the sedimentary facies and environmental evolution. After stratigraphic correlation of SK and SR boreholes, the result indicates that the geological boundary between the late Cretaceous Mingshui formation and the Paleogene Yi’an formation is at the depth of 115 m. The magnetotelluric sounding anomaly areas are corresponding with the unconformities, which are equivalent to seismic horizon T03, T1, T2, and T3, respectively. In addition, the typical “steer’s-head” geometry in the magnetotellurics indicates that the SLB has experienced five evolution stages.

Published: November 2020

AbstractMaladaptive stress-related behaviors are integral to multiple complex psychiatric disorders, and it has been well established that serotonergic signaling mediates various aspects of these maladaptive states. In these studies, we sought to uncover the function of a previously undefined serotonergic pathway, which projects from the interpeduncular nucleus (IPN) to the ventral hippocampus (vHipp). Intersectional retrograde and chemogenetic viral manipulation strategies were employed to manipulate the function of the IPN-vHipp pathway during a variety of behavioral measures in male mice. We found a significant effect of circuit inhibition on behaviors associated with coping strategies and natural reward. Specifically, inhibition of the IPN-vHipp pathway dramatically increased active stress-induced escape behaviors, in addition to moderately affecting sucrose consumption and food self-administration. During inhibition of this pathway, agonist activation of serotonergic 5-HT2A/2Creceptors in the vHipp reversed the effects of IPN-vHipp circuit inhibition on active escape behaviors, thereby supporting the synaptic mechanism underlying the behavioral effects evidenced. IPN-vHipp inhibition did not induce differences in generalized locomotion, anxiety-associated behavior, and intravenous nicotine self-administration. Importantly, these findings are in opposition to the canonical understanding of serotonin in such escape behaviors, indicating that serotonin exerts opposing effects on behavior in a pathway-specific manner in the brain. Taken together, these findings thereby have important implications for our understanding of serotonergic signaling and associated therapeutic approaches for the treatment of disease symptomology.
High Performance Liquid Chromatographic Analysis of Rutin in Allium Species from Bosnia and Herzegovina
Authors: Salihović Mirsada , Sofić Emin 
Published: November 2020

Rutin is quercetin heteroside widely present in plants that exhibit many health-beneficial effects, such as strengthening the capillary walls, reducing the harmful effects of LDL cholesterol, and reducing the risk of cardiovascular diseases. Rutin was determined from three &lt;i&gt;Allium&lt;/i&gt; species (&lt;i&gt;A. cepa&lt;/i&gt;, &lt;i&gt;A. sativum&lt;/i&gt;, and &lt;i&gt;A. ursinum&lt;/i&gt;) collected in Bosnia and Herzegovina by the HPLC method associated with electrochemical detection. The analysis was performed from methanol extracts of bulb and leaf of garlic, bulb and leaf of onion, and leaves of wood garlic. Rutin was present in all of the examined samples. The highest rutin content was found in garlic leaves (0.78 ± 0.09 mg g&lt;sup&gt;–1&lt;/sup&gt;), and the lowest in onion bulbs (0.04 ± 0.10 mg g&lt;sup&gt;–1&lt;/sup&gt;). The contents of rutin were higher in leaf samples, suggesting that leaves of onion and garlic are recommended as a better natural source of this glycoside.

Published: November 2020

The influence of ultrasound cavitation in the atmosphere of different gases, namely oxygen, air, and nitrogen, on the destruction of impurities of butanol and ethanol found in wastewater from the pharmaceutical plant “Galichpharm” was investigated. The effect of the corresponding gases (oxygen, nitrogen, and air) without ultrasound cavitation on the destruction of ethanol and butanol impurities in wastewater was comparatively investigated. The degree of oxidation of organic matter, effective rate constants, and approximation coefficients were calculated. It was found that the air supply is the least effective for both ethanol and butanol impurities. Degradation of ethanol by air contributed to the reduction in the organic matter content by 14.6 %, while oxidation of butanol was not observed. Ultrasound cavitation enhanced the effect of air and in common action with air the ethanol impurity content reduced by 32.58 %, and butanol impurity by 4.05 %. Nitrogen bubbling produced mediocre results for the destruction of ethanol and butanol impurities giving a decrease by 17.04 % and 0.67 %, respectively. The highest results were obtained with oxygen. Ethanol impurities decreased by 22.47 % and butanol impurities by 1.75 %. With the common action of oxygen and ultrasound, much higher results were obtained, 44.32 % for ethanol impurities and 7.43 % for butanol impurities.

Chervinskiene’s book discusses her experiences being deported to the Altai region and Yakutia, part of the wave of deportations from Lithuania that began in the fateful year of 1941. The early traumatic experience determined not only the author’s further personal life but also her professional choice. It is stated that the chosen field of scientific and creative interests of the expert on classical Russian literature, author of books and articles about L. Tolstoy, F. Dostoevsky and A. Chekhov, was also shaped by the all of the human experience gained during this tragic stage of her life.
On Some Features of Osip Mandelstam’s Representation in the Memories by Anna Akhmatova
Authors: Mikhailova Galina 
Published: November 2020

The article presents some considerations on the motives for the creation and text strategies of Akhmatova’s memories of Mandelstam. The Pages from a Diary are viewed from two points of view: first, as a fragment of Akhmatova‘s memoir prose of a certain historical time, as an actualization of personal memory in order to correct collective cultural memory; secondly, as a supertext formed by numerous drafts, lists and variations.Within the framework of this genre, it is possible to single out a number of principles that Akhmatova is guided by when creating a memoir text: for example, a dialogical mode of a “conversation” with existing memories, documents, oral evidence; intention of myth-fighting, etc. A look at the Pages from a Diary as a work of narrative prose (based on Akhmatova’s definition of memories as a “short story”), called “The Death’s Way,” allows us to add the hero of her memoir to a number of “damned poets” that are not alien to Mandelstam.
Primary Care Use and Assessment of Adolescents’ Sexual Health During Hospitalization
Authors: Clary Kathryn , Cortright Lindsay , Tumin Dmitry , Buckman Cierra , Eldridge David 
Published: November 2020

OBJECTIVES:
Hospitalization provides an opportunity to address sexual health needs of adolescents who may not otherwise receive regular medical care. We investigated documentation of a sexual health discussion with adolescents hospitalized at our medical center to determine if previous primary care physician (PCP) visits in the same health system were associated with sexual health documentation during the hospital admission.

METHODS:
We retrospectively identified adolescents aged 13 to 17 years discharged from the pediatric general ward. Documented discussion of sexual health was reviewed in the electronic medical record. Previous PCP visits were identified from the affiliated primary care clinics within 12 months before hospitalization. We also queried follow-up PCP visits within 90 days of discharge to determine if a sexual health discussion during hospitalization was followed-up in the outpatient setting.

RESULTS:
We analyzed 394 patients (49% girls; median age 15 years), of whom 122 (31%) had documentation of a sexual health discussion while hospitalized and 75 (19%) had previous PCP visits in our health system. On multivariable analysis, older age (P &lt; .001), female sex (P = .016), admission from the emergency department (P &lt; .001), and a genitourinary primary problem at admission (P = .007), but not previous PCP visits, were associated with increased likelihood of sexual health documentation.

CONCLUSIONS:
Although discussion of sexual health was uncommon overall for hospitalized adolescents, we noted that nearly 4 in 5 adolescents for whom this was documented had not recently visited a PCP in our health system. These findings highlight hospitalization as a unique opportunity for sexual health intervention among adolescents who may not regularly see a PCP.
Ceridwen Dovey’s Only the Animals and the Politics of Re-interventions on Anthropocentrism
Authors: Rahaman Habibur 
Published: November 2020

This article ascertains how Ceridwen Dovey’s Only the Animals (2014) aligns with interdisciplinary studies which critique anthropocentric binaries of human-nonhuman relationships. Drawing on a critical analysis of the selected stories of the book, this article attempts a broader study of Dovey’s book. Dovey’s ten stories are, as the article argues, a radical re-narrativisation against human-nonhuman binaries lying in the creative-cultural human world. It also sees the book as a subversive interrogation of human superiority. The ten animals of this book, then, are not mere metaphoric or symbolic embodiments of human sufferings, rather they represent an autonomous world of beings. These beings, as Dovey projects, challenge the human world’s cultural and creative ways of using and subjugating nonhuman beings to consolidate a human-centric world system. This article hinges on this aspect of the assertive nonhuman identity vis-à-vis the human identity, in particular, and then theoretically underpins Dovey’s book’s significance through some ecocritical and post-human lenses.
Recourse action against investigative authorities is a legal way of «fall guys:» identifying who made a mistake in the criminal procedural system
Authors: Kovtun Kovtun N. 
Published: November 2020

The author indicates how and in which ways tendencies of recourse recovery from guilty persons of investigative authorities can be realized. The article reviews practical experience of recourse actions disposition over the last years in the Russian Federation. From the authors point of view, this practical experience is confusing, conflicting, and potentially hazardous.
In 2018, the Law Commission of the Government of the Russian Federation endorsed a bill aimed at improving recourse actions against investigative authorities. The legal fundamentals of the bill are stated in regulations of Chapter 18 the RF CPC and again in Articles 1069, 1070, 1080, sub-paragraphs 3 and 3.1 of the Article 1081 of the CCRF. The main idea of the bill is to improve the subjects and practice of recourse recovery from guilty parties of investigative authorities and other law enforcement agencies of those funds that were disbursed to rehabilitees from the Treasury of the Russian Federation account in accordance with Chapter 18 of the RF CPC [1]. The Russian Federation State Duma presented a bill in 2019 that specified the minimum amount of state monetary compensation for unwarranted prosecution of such persons who (in future) would be liable to rehabilitation. There are some innovations of the given bill. The minimum compensation per rehabilitee is 1000 RUB for each day of pretrial investigation and judicial inquiry; 5000 RUB per day for illegal use of such restrictive measures as house imprisonment, restraining order, and written undertaking not to leave the place; and 15 000 RUB per day of illegal stay in pretrial detention facility [2].
If these new measures are accepted, the amounts of recourse against investigative authorities will be cardinally increased. The keys of the above-noted lie in growing statements. The main point of these statements is that the federal budget loses huge sums annually and irrevocably through the realization of institute rehabilitation.

Background: Tobacco use is the single, largest preventable cause of death and disability worldwide. Area-specific community-based epidemiological studies on tobacco use are required to quantify the problem, identify the determinants and their distribution. The objectives were to find out the prevalence, patterns and socio-demographic correlates of tobacco use in Davangere taluka, Karnataka, India.Methods: This was a community-based, cross-sectional study of 2008 subjects (>10 years of age) in urban and rural areas of Davangere taluka, Karnataka. Interviews were conducted by using a structured, pre-tested questionnaire by house-house visits. Results are presented using percentages, chi-square test, odds ratio and multiple logistic regression analysis.Results: The prevalence of tobacco use was 30.7%. Among urban males it was 39.5%, rural males 39.6%, rural females 26% and urban females 18.5%. Tobacco use was significantly associated with sex, locality, religion, caste, marital status, family type, occupation, and tobacco use in family or friends. There was direct relationship of tobacco use with age and inverse relationship with education and socio-economic status. Mixed tobacco use was higher in rural areas compared to urban areas. About 73.9% of 10-29 years persons had started before the age of 18 years. Among older participants there was higher frequency of consumption and duration of use.Conclusions: Tobacco use is common and it is influenced by various local socio-demographic factors. Addressing these factors and providing tobacco cessation services should be included as key strategies in tobacco control.

The Special Efforts Program (Upsus) is an Indonesian government program to increase production/productivity of lowland rice to support the realization of food self-sufficiency. The Upsus targets are to increase the planting index by 0.5 and productivity by 0.3 tons/ha/GKP. The increase in planting index is achieved by the expansion of added planting, but the increase in productivity has not been reached optimally due to pest and disease attacks. The objective of this research was to determine the knowledge, attitudes, and actions of Upsus farmers in controlling pests and diseases, rice cultivation techniques, and implementation of Upsus in Karawang District. The research was conducted by distributing questionnaires to 60 farmers in Tempuran and Tirtajaya Sub-District at Karawang District. The respondents were selected by purposive sampling with the consideration of respondent being an active farmer, having at least 5 years of farming experience, and has ben a member of Upsus for at least 1 year. Most respondents have age in the range of 41-60 years, the highest education of elementary school, and have farming experience for 5-10 years. Pests and diseases are the biggest problems faced by the farmers. Upsus farmers used Ciherang and Inpari 32 varieties and the applications of pesticides were conducted according to the schedule. Most of the farmers could not distinguish between pests and diseases. The dominant pest and disease control carried out was the use of chemical pesticides.

Penggunaan Input yang Optimal pada Usaha Tani Kedelai (Suatu Kasus di Desa Sukahurip, Kecamatan Pangatikan, Kabupaten Garut, Jawa Barat)
Authors: Suminartika Eti 
Published: November 2020

The majority of soybean supply is fulfilled by importation and the import of soybean tends to increase. The dependency of Indonesia on imported soybean indeed becomes a serious issue in maintaining food security and local production of soybean is low and quite decreasing. The low domestic soybean production might be caused by the inappropriate used of inputs. Many cases found in the field are the inefficient uses of input factors. The purpose of this study is to analyze the factors influencing the soybean production and to analyze the optimal level of input use in soybean production. The study was conducted in the Sukahurip Village, Pangatikan Sub-District, Garut District, West Java in July 2018. The research method used was a survey method. The data used consisted of primary and secondary data. Primary data were obtained from samples of soybean farmers and samples of farmers were taken by a simple random sampling. The data were analyzed by Cobb Douglass`s Production function (to analyze factors affecting soybean production) and the NPM that was equal to BKM formula was used to determine the optimal level of inputs use. Factors influencing soybean production are land and seeds. Land use, seeds, and ZA fertilizer have not been used efficiently because of the limited land use and the use of substandard inputs. The addition of inputs to the optimal level is 1.36 hectares of land use and 52.7 kg of seeds that will maximize the profits.
