Authors: Schwartz Harold , Marushka Lesya , Chan Hing Man , Batal Malek , Sadik Tonio , Ing Amy , Fediuk Karen , Tikhonov Constantine 
Published: June 2021

Abstract
Objectives
Pharmaceuticals are emerging contaminants in the environment. Little has been published about the presence of pharmaceuticals in waterbodies nearby or on reserve land of First Nations in Canada. The objectives of this study were to (1) quantify the level of pharmaceuticals in First Nations’ surface waters, (2) calculate the human health risks of the mixtures found, and (3) measure the exposure to pharmaceuticals in First Nations’ drinking water where source water was highly contaminated.

Methods
This participatory study measured the levels of 43 pharmaceuticals from surface water samples taken at three water sampling sites chosen by the 95 participating First Nations. The sites were in proximity to recreational areas, fishing areas, drinking water sources, and/or wastewater outflows. When elevated levels of pharmaceutical mixtures were found in samples, drinking water samples were obtained and analyzed for potential pharmaceuticals. Human health risks were calculated by an established protocol.

Results
In total, 432 samples were collected at 302 water sampling sites (285 surface water, 11 drinking water, and 6 wastewater sites). Quantifiable levels of 35 pharmaceuticals were found in 79 of the 95 (83%) participating First Nations at 193 of the 285 surface water sites (68%). Overall, the levels found were comparable to or lower than those found in other studies in Canada and worldwide.

Conclusion
In almost all participating First Nations, there is no human health risk from consuming surface water for drinking. However, surface water in the vicinity of major urban centres should not be used as secondary untreated water sources due to the elevated human health risk associated with exposure to the mixtures of multiple pharmaceuticals detected.
Does TB stigma affect emotion recognition? A study with a Portuguese sample
Authors: Nascimento Teresa Maria , Bianchi Mauro 
Published: June 2021

TB stigma constitutes a major barrier to disease control and social distress. This study aims to understand better the inherent social processes on the perception of emotions. Thus far, the specific role of TB stigma in this respect was not tested. We hypothesize that individuals in TB treatment (vs. a control non-clinical group) would identify more negative emotions in the faces of others, specifically rejecting emotions (e.g., disgust) when preoccupied with TB stigma. Two groups of participants completed a questionnaire with 23 faces, identified the emotions portrayed in the pictures, and reported their level of Stigma Consciousness, Interpersonal-Rejection Related to Stigma, and Rejection Sensitivity. Results show that the two groups significantly differ in their perceptions of negative emotions: participants in treatment identify less disgust and more sadness, fear, and anger versus the control group. Findings are discussed concerning the literature on stigma and its consequences.
Representaciones Sociales sobre Emociones y Masculinidad en Hombres Bogotanos Social
Authors: Mendieta-Izquierdo Giovane , Tinjaca-Prada Diana Patricia , Cuevas-Silva Juan María 
Published: June 2021

This article aims to identify the content and organization of social representations about the concept of emotions and masculinity of young Bogota men, from a qualitative study design in the light of social representations through associative techniques such as free listings and questionnaires. In comparison by pairs to 20 young men with employment in Bogotá, Colombia, by means of proactive sampling and convenience, the analysis was carried out in the light of graph theory, after identifying the distance index. It was found that the social representation of the emotion concept is related to a feeling associated to success and motivation, as well as to emotional expressions such as: anger, joy, sadness and happiness. The masculinity concept is permeated by hegemonic elements, linked to strength, power, domination and manhood, related to responsibility and work. It is concluded that the social representation of the concepts of masculinity and emotion is diverse, it is reconciled in several peripheral elements which can be fractured and generate mobility in social representation recognizing the mandates of hegemonic masculinity and male stereotypes.
Gabriel Marcel i etyka heterocentryczna
Authors: Węcławski Michał 
Published: June 2021

Artykuł przedstawia etyczny wymiar refleksji filozoficznej Gabriela Marcela. Na tle szeregu obecnych w niej kategorii (m.in. próba, zdrada, wspólnota, ofiara, obecność, rozporządzalność, intersubiektywność, miłość) zostaje ona określona mianem heterocentrycznej. Pojęcie to, zaczerpnięte z pism samego Marcela, znajduje tu zastosowanie w celu odróżnienia od ugruntowanych już w literaturze przedmiotu, ale dotyczących zwłaszcza koncepcji późniejszych, nazw w rodzaju „filozofia innego” czy „dialektyka tożsamości i różnicy”; w ogólności dotyczy postawy zwrócenia się ku temu, co inne, które zarazem prowadzi do wewnętrznego samoodzyskania. Przed znajdującym się w drodze człowiekiem stoi zadanie odpowiedzi na wezwanie płynące zarówno z jego wnętrza, jak i z czegoś poza; ostatecznie jego celem staje się, by umocować własne istnienie w głębi rzeczywistości, która je przekracza. Wskazane przy tym zostaje, że etyka Marcela nie unika ontologii, a odpowiedź na pytanie o to, jak żyć, jest nierozerwalnie złączona z refleksją nad byciem.
Ambiwalencja greckiej nadziei
Authors: Filek Jacek 
Published: June 2021

Artykuł jest próbą odtworzenia myślenia Greków o fenomenie nadziei. Stwierdzona zostaje wielopoziomowa jej ambiwalencja. Najpierw jako spodziewanie się albo czegoś dobrego, albo czegoś złego. Następnie jako nadzieja negatywna (w znaczeniu nieuzasadniona, nierozumna i prowadząca do zguby) bądź pozytywna (w znaczeniu uzasadniona, rozumna i umożliwiająca ocalenie). Na koniec jako nadzieja moralnie dobra bądź zła w zależności od etycznej oceny jej przedmiotu. Stwierdzona zostaje też korelacja strachu i nadziei. Postawiony zostaje problem odniesienia nadziei do czasu. W tym kontekście są rozważane są poglądy Hezjoda, Tukidydesa, Platona, Arystotelesa i stoików.
Filozof do filozofa. Wokół listu Bolesława Micińskiego do ks. Augustyna Jakubisiaka
Authors: Zajączkowski Ryszard 
Published: June 2021

W artykule zaprezentowano nieznany list Bolesława Micińskiego do ks. Augustyna Jakubisiaka znaleziony w jego archiwum w Bibliotece Polskiej w Paryżu. Jest to okazja do przypomnienia tych wybitnych, choć nieco zapomnianych filozofów oraz do prezentacji ich powiązań intelektualnych. Poznali się w 1937 r. w Paryżu i odtąd utrzymywali bliskie kontakty, aż do śmierci Micińskiego w 1943 r. Od początku łączył ich sprzeciw wobec idealistycznej filozofii niemieckiej oraz neopozytywizmu Koła Wiedeńskiego z jego materializmem, scjentyzmem i sceptycyzmem. Miciński odkrywał u ks. Jakubisiaka bliskie sobie poglądy na temat przestrzeni i czasu. W ostatnich esejach Micińskiego z okresu wojny pojawiają się tezy o charakterze moralnym, które głosił ks. Jakubisiak, a mianowicie jednostkowość i autodeterminizm. Jednostkowość oznacza dowartościowanie jednostki w obliczu wszystkiego, co może jej zagrażać, zwłaszcza totalizmów. Z kolei autodeterminizm to przyznanie ludzkiemu bytowi absolutnej autonomii i wolności, która działa w przyjętym uprzednio kierunku. Było to zanegowanie determinizmu i ateizmu. Konteksty wypowiedzi Micińskiego na temat jednostki i autodeterminizmu (a także słabiej zarysowane problemy czasu i przestrzeni) wskazują, że nie tylko przejął on od Jakubisiaka istotne dla niego pojęcia, lecz także osadził je w bliskim sobie kontekście światopoglądowym. Myśl polskiego duchownego musiała być dla Micińskiego podwójnie inspirująca. Po pierwsze, odkrywał w jego pracach znane sobie style filozofowania wywodzące się od św. Augustyna, Leibniza, Pascala czy Kanta. Z drugiej strony poszerzał pola własnych poszukiwań i znajdował odpowiedzi na istotne egzystencjalne pytania; zwracał się w kierunku współczesnej nauki (chociażby teorii Einsteina), a zwłaszcza chrześcijaństwa, które stawało się dla niego coraz ważniejszym intelektualnym i duchowym azylem.

Marker-assisted breeding of onion (<i>A. cepa L.</i>) maintainer line resistant to Downy mildew
Authors: Eidlin Ya. T. , Monakhos G. F. , Monakhos S. G. 
Published: June 2021

Relevance. F1 hybrids breeding programs of onion are based on the use of nuclear cytoplasmic male sterility (NCMS). Breeding and seed production based on NCMS suggest a development of a female sterile maternal line, a maintainer line and a paternal component. The development of an isogenic pair of sterile line – maintainer line is one of the most labor-, time-consuming and intellectually-intensive stages of a breeding program, the implementation of which becomes more complicated with an increase in the number of traits / genes for which selection is carried out.Methods and results. This paper presents a genetic scheme for the development of a Downy mildewresistant (pathogen P. destructor) maintainer line of onion using marker-assisted selection (MAS). F2 populations were obtained from the cross of the female maintainer inbred line, Bn1- (13) (genotype – cytN msms pdpd) and male inbred line resistant to Downy mildew, No. 136 (genotype – cytT MsMs PdPd). DNA marker DMR1 were used for Downy mildew resistance gene Pd, jnurf13 – for maintainer gene ms and marker system 5`cob: orfA501 – for N, S and T cytoplasms. It was shown that the MAS application allow to develop a stable Downy mildew resistant maintainer line cytN msms PdPd in two generations.

Relevance. Shallot is the universal culture in terms of its economically valuable indicators. Breeders in the south of Western Siberia carry out a lot of research work with the aim of creating varieties for Siberian conditions. Long-term studies have made it possible to select promising samples, and exceeding in their indicators the value of signs of released varieties.Materials and methods. The studies were carried out in field and laboratory conditions on the basis of the West Siberian Vegetable Experimental Station in the Priobskaya zone of the Altai Territory in 2016-2020. Research objects: samples of the nursery of competitive variety testing. Three appreciable forms No. 37, No. 39 and No. 48 passed competitive variety testing and, according to the results of the research, were transferred to the State Variety Testing.Results. Sample No. 39 showed marketable yield, which exceeded this indicator of the standard variety by 23.7% and amounted to 23.2 t/ha. The average weight of the sample No. 39 marketable bulbs was 29.0 g, for the standard variety it was 23.4 g. The content of vitamin C in the bulbs and leaves of the new sample exceeded these indicators of the standard variety by 0.3% and 0.53%, respectively. In 2018, sample No. 37 was transferred to the State Variety Testing. This sample belongs to the early maturing group. The bulbs yield of the new sample during all the years of testing significantly exceeded the yield of the standard variety and amounted to 20.3 t/ha (2016- 2018). Sample No. 48 was submitted to the State Variety Testing in 2020. The excess in bulbs yield of this sample was (2019-2020): 13,3%, leaves – 18,8%. In 2019, the Sharm variety was zoned and entered into the State Register of Breeding Achievements, in 2020 – the Chance variety. Sample No. 48 with the proposed name Pharaon has been undergoing the State Variety Testing since 2021.

Published: June 2021

Abstract
The physical property heterogeneity of tight sandstones was mainly caused by complex alteration of various diagenesis combinations during burial process. However, diagenetic evolution of different diagenesis combinations which generally result in the strong difference and heterogeneity of physical property and pore structure is rarely well understood. The Middle Permian lower Shihezi Formation is one of the most important tight gas sandstone reservoirs in the Hangjinqi area of Ordos Basin, China. The reservoir heterogeneity of lower Shihezi Formation, which was caused by the differential diagenesis combination, is crucial to efficient exploration and development. Evolution mechanism of differential diagenesis combination and its effect on the reservoir quality in the tight lower Shihezi Formation sandstone in the Hangjinqi area of Ordos Basin was investigated by means of thin-section description, cathodoluminescence (CL) imaging, X-ray diffraction (XRD), scanning electron microscopy (SEM), and homogenization temperature of fluid inclusions. The lower Shihezi Formation sandstones can be divided into four diagenesis combination types according to the reservoir characteristics and diagenetic relationship. The main diagenetic sequence was mechanical compaction-chlorite rim-early pore-filling calcite cementation-dissolution-authigenic kaolinite-quartz cementation-late calcite cementation. Differential diagenesis combination was mainly controlled by the petrological characteristics, microfacies, and fault. Low content of rock fragment and high content of detrital quartz were beneficial to the compaction resistance and cementation. The moderate content of pore-filling calcite was conducive to pore space protection and feldspar dissolution. The faults control dissolution and differential diagenesis combination by influencing the migration of acid fluids. Moderate compaction-moderate cementation-moderate dissolution type (BBB type) and weak compaction-moderate cementation-strong dissolution type (CBA type) were in favour of high-quality reservoir development.
Simulation Study Investigating the Impact of Carbon Dioxide Foam Fracturing Fluids on Proppant Transport

Published: June 2021

Abstract
Production from unconventional reservoirs using hydraulic fractured wells has recently gained much attention due to its ability to increase recovery to high percentages. The placement of proppant in fractures plays a significant role in conductivity of fractures and well productivity. Here, we aimed to elucidate some basic concepts of the technique using FracPro simulator. FracPro and hydraulic fracturing consist of many design parameters that effect the results of the stimulation process. Of the many parameters that exist, three were focused on in this paper: proppant transport, the use of carbon dioxide (CO2) foam fracturing fluid, and the use of low specific weight versus higher specific weight. FracPro was also used to simulate the results of using a low specific gravity value of 1.9, a medium value of 2.7, and a high value of 3.5. The concentration of CO2 was also varied in each condition; concentrations of 30, 50, and 70% were used. After running investigating these scenarios, some unexpected results were obtained. Notably, a lower specific gravity should produce a longer effective proppant length; however, our data indicates shows the opposite.
