Highly efficient, ultra-compact, and ultra-broadband bidirectional vertical coupler based on spin-directional locking
Authors: Pezeshki Hamed 
Published: August 2022

An ultra-compact and ultra-broadband polarization-selective bidirectional vertical coupler is proposed. The coupler is designed by coupling unique two-plane chiral

-shaped plasmonic nanoantennas on top of a silicon-on-insulator waveguide. By taking advantage of the spin-directional locking principle and coupled nanoantennas, a circularly polarized incident light can be coupled into a specific direction through the waveguide, depending on its spin. Based on the full-vectorial finite element method, for a beam radius of 0.53 µm, the coupler with a size of

Sexual experiences of cancer survivors: A qualitative study in Jordan
Authors: Al-haddad Muhammad , Alananzeh Ibrahim M. , Green Heidi , Alomari Albara , Fernandez Ritin 
Published: August 2022

Background
In Jordan, cancer is the second leading cause of death after cardiac disease. The impact of cancer on sexual relationships is a taboo subject and hence, such issues are underreported research among Jordanian people examining unmet needs.

Aim
To examine the experiences and preferences of Jordanian cancer survivors related to communication regarding their sexual needs.

Methods
Qualitative study conducted between May and June 2020 using semi-structured face-to-face interviews using the snow-balling approach for recruitment. Participants were recruited until data saturation was obtained and data were analyzed using qualitative thematic analysis.

Results
Analysis of participants’ interview data identified three main categories: 1) The psychological impact of cancer of sexual relationships; 2) Physician support; 3) Variations in sexual life and sexual experiences.

Conclusion
The study revealed that there is a substantial psychological impact of cancer on sexual relationships among Arab Jordanian cancer survivors. Feeling powerless, being labelled as ‘sexually disabled’, and lack of communication with physicians were emphasized by participants as a barrier to discuss sexual needs with their physicians. Lack of physicians support negatively impact Jordanian cancer survivors sexual experience and led to increased their sense of powerlessness and loss of control over sexual relationships.

Implications for practice
Overall, the study indicated a crucial need for physicians to encourage patients to disclose their sexual experience to help them maintain their sexual and mental health while in the fight against cancer. The physicians, nurses and allied health professionals should be engaged in the conversation with patients by taking an active role in the discussion. Additionally, the family and partners of the patients should also be approached and engaged by health professionals in the discussion to address their needs or sexual issues.
Seasonal dynamics of the photosynthetic apparatus parameters of upright and prostrate pine species using the example of Pinus sibirica and P. pumila
Authors: Bender O. G. 
Published: August 2022

The seed progeny photosynthesis intensity and the photosynthetic apparatus state of genus Pinus species of different life forms were studied in seasonal dynamics: P. sibirica is an upright tree, P. pumila is a prostrate species. The seed progeny age was twelve years old. The photosynthesis intensity of both species increased from May to July, was maximum in July and amounted to 9.2 mg CO2 mg-1 fr. m. h-1 in Siberian stone pine and 7.8 mg CO2 mg-1 fr. m. h-1 in Siberian dwarf pine, in August the assimilation activity began to decrease in both species. Studies have shown that in summer P sibirica had photosynthesis values 15-20 % higher than those of P pumila. In the winter months, the chlorophyll content did not differ significantly between the species; at the same time, during the growing season, Siberian stone pine contained more photosynthetic pigments than Siberian dwarf pine. An assessment of the photosynthetic apparatus functional activity showed that the seasonal dynamics of the maximum quantum yield photochemistry (Fv/Fm) of photosystem II (PSII), the real quantum yield of PS II ^psII) in both species had a similar character: Fv/ Fm sharply decreased from November to February, increased from March to June, reached its maximum values and practically did not change in June-Septem-ber and decreased in October. The electron transport rate (ETR) was minimal from November to April, increased sharply in May, and had maximum values in May, June, and July. In August, a significant decrease in ETR was observed. The rate of electron transport significantly differed between species in May-September and was significantly higher in Siberian stone pine. The shown differences between the P sibirica - upright species, compared to P. pumila - prostrate species, indicate species specific physiological parameters.

Published: August 2022

The Almaty region is one of the most economically developed regions of the Republic of Kazakhstan, where cadastral assessment has not been carried out so far. A comprehensive cadastral assessment was undertaken for the first time within the framework of the scientific and technical program (2021-2023) which takes into account the most important components of biological diversity (flora, vegetation, plant resources), sustainable use, conservation and reproduction of phytogenetic resources of the Almaty region. As a result of research in 2021 on the territory of 7 administrative districts of the region, an annotated list of flora of higher vascular plants (2414 species), algae (377 species and varieties), mycobio-ta (1266 species of micromycetes and 356 species of macromycetes) was compiled. A phytocenotic assessment was carried out on the basis of 144 geobotanical descriptions, a list of plant communities was compiled, grouped into 6 types of vegetation. The stocks of fresh raw materials for 8 species of economically valuable plants have been identified. Operational stock form 4 species: Juniperus pseudosabina, Rumex tianschanicus, Berberis sphaerocarpa, Alhagi pseudalhagi. Locations and maps of 14 rare species and 19 rare communities have been determined. Locations of 29 alien plants, including 4 invasive species, have been identified. 25 forms of the Sievers apple tree and 26 forms of the common apricot of high value for breeding were selected.

Authors: Goncharova I. A. , Skripalshikova L. N. , Barchenkov A. P. 
Published: August 2022

The Orchid species cenopopulations (Cypripedium calceolus, C. macranthon, C. guttatum, Neottianthe cucullata) growing in Krasnoyarsk suburban pine cenoses at the forest-steppe were studied. Orchid species are included in the Red Book of the Krasnoyarsk Territory. The investigation objectives are Orchid species occurrence studying and population’s age structure determining in the Krasnoyarsk suburban pine cenoses, both under recreational load and in control. The results of the four species occurrence dynamics at the period 2017-2021 in the control cenosis and cenoses under the anthropogenic influence are presented. In the studied period, the Neottianthe cucullata occurrence did not change, regardless of the level of recreational impact. This species blooms in August, when the recreant’s activity decreases, which can explain its numbers preservation at the same level. The Cypripedium occurrence dynamics depends on the degree of recreational impact. As a result of the ontogenetic analysis, the populations of Neottianthe cucullata, Cypripedium macranthon, and C. guttatum in the control sample area belong to the middle-aged normal complete populations. Populations of Neottianthe cucullata, Cypripedium macranthon, C. calceolus in suburban pine cenoses under the recreational impact should be classified as middle-aged normal incomplete.

Authors: Mitrofanova E. Yu. 
Published: August 2022

The subglacial phytoplankton of the Lower Ob was studied at three sites in the area of Salekhard in March -April 2021. 71 taxa of algae from Cyanobacteria, Chrysophyta, Bacillariophyta, Cryptophyta and Chlorophyta were identified with a predominance of diatoms (55 %), among which they were noted as true plankters (representatives of 5 genera), as well as those that live in benthos and fouling (15 genera). Aulacoseira granulata and Stephanodiscus hantzschii, as well as unknown small spherical and filamentous cyanobacteria, were found at every station and section. Among the surveyed sections, the maximum number of taxa was found at the section of the Malaya Ob (Azovy - 38), slightly less at the sections of the Bolshaya Ob (Kazym-Mys - 36 and Salemal -- 34). The number of algal divisions, on the contrary, was lower on Azovy than on Kazym-Mys and Salemal (four and five, respectively). An ecological and geographical analysis of the composition of winter phytoplankton showed that it was dominated by representatives of plankton in terms of habitat, cosmopolitans in terms of geographical confinement, indifferences in relation to the pH of the environment and alkaliphiles in relation to water salinity, as well as betamesosaprobionts in relation to the content of organic compounds.

Authors: Pyatina I. S. , Reut A. A 
Published: August 2022

The results of studying the morphology and germination of seeds of 7 species of the genus Hemerocallis L. (H. citrina, H. dumortieri, H. esculenta, H. lilioasphodelus, H. middendorfii, H. minor and H. thunbergii) introduced in the conditions of the forest-steppe zone of the Bashkir Cis-Ural are presented. The morphology of seeds (color, shape, size) is described. It is shown that the seeds are round-ovoid, slightly angular, black, glossy, shiny; surface is flat and smooth. The average value of seed length in species varied from 4,5 to 6,4 mm, width - from 3,1 to 4,7 mm. A morphometric difference in the size and weight of seeds from different populations was revealed. The studied features are of taxonomic significance and can be used to determine the species of daylilies. It is noted that the seeds of the studied species are characterized by shallow endogenous physiological dormancy. It was revealed that the indicators of seed germination depend on the species characteristics and germination conditions. In general, the germination rate of the species was 8,3-95,0 %. It was established that after 60 days of seed stratification at a temperature of 3-4 °C, the germination rate in most daylilies increased by 1,2-1,8 times. The results obtained can be used in breeding and ontogenetic studies during the introduction of representatives of the genus complex Hemerocallis.

Authors: Saitjanova U. Sh. 
Published: August 2022

The article presents the phytocenotic characteristics of the Kalidium capsicum, Halocnemum strobilaceum pasture variety (PV), which is a part of the Halocnemum strobilaceum pasture type. The described type of pasture is widespread in the central part of the Karakalpak Ustyurt. Kalidium capsicum, Halocnemum strobilaceum pasture variety (PV), on wet and plump salt marshes, with Haloxylon ammodendron, H. strobilaceum on gypsum plump salt marshes, with the participation of Reaumuria songarica, Kalidium caspicum on cones of temporary watercourses in combination with Anabasis salsa is located in the Kungrad district, geographical points: Barsakelmes, Shorja. The area of the pasture variety (PV) is 36075 ha. The total projective cover of the PV is 15 %. The high proportion in vegetation is assigned to real halophytes: Haloc^mum strobilaceum - 40 %, and K. caspicum slightly less - 33 %; a smaller share on Haloxylon am-modendron - 20 % and a small part on Anabasis salsa - 7 %. All species except Halocnemum strobilaceum and Kalidium caspicum as assemblers of this plant community are found isolated and their role in the addition of the projective cover of the herbage is small. According to the results of the study, we see that due to the arid climate, the eaten part of the forage mass of the Kalidium capsicum, Halocmmum strobilaceum pasture variety is low and ranges from 1.9 to 4.2 c/ha. According to the yield indicators, the K. caspicum, Halocmmum strobilaceum pasture variety can be recommended for use as autumn-winter pastures.
Biological reserves of bracken fern (Pteridium aquilinum (L.) Kuhn) in the coniferous forests of Altai Krai
Authors: Sokolova G. G. 
Published: August 2022

The article presents information on the biological resources of the bracken fern (Pteridium aquilinum (L.) Kuhn) in the coniferous forests of the Altai Krai. Bracken fern is one of the most widespread ferns in the Altai Krai. It often dominates in grass cover in both deciduous and coniferous forests. The author gives a morphological description of the plant, characterizes the features of growth and development, considers the influence of environmental factors (temperature, humidity, lighting, anthropogenic activity) on the distribution and abundance of this species. The article provides data on biological productivity of bracken fern in different natural zones of Russia. The regularities of changes in the biological productivity of the bracken fern were revealed depending on the habitat conditions. In the Altai Krai, commercial harvesting of bracken fern is carried out in various types of forests. Long-term exploitation of the same lands leads to a decrease of resources and disruption of the natural populations’ structure. To study the current state of populations and identify the biological and commercial stocks of bracken, we examined coniferous forests (fir and pine forests) in the zones of mass harvesting of bracken - in the Priobsky Bor area and in the Salair ridge zone. In the study area, 68 key sites in various groups of forest types were established by random sampling. At each site, geobotanical descriptions of the forest community were carried out, the number of fronds, the density of standing, the projective cover and the average weight of one frond were determined. The data obtained are extrapolated to the entire study area. Studies show an extremely uneven distribution of bracken fern in forest types and individual regions. During the research period, the biological, economic and operational stocks of bracken fern were determined and recommendations were given on the amount of annual harvest in various types of forests.
On the seed science of representatives of the genus Feather grass (Stipa L., Poaceae Barnhart), included in the Red Book of the Nizhny Novgorod Region

Published: August 2022

Data on the morphology of fruits and seeds is important in plant identification, especially for botanical gardens, which receive a significant part of planting material in the form of seeds. We studied 18 seed samples of 7 feather grass species listed in the Red Data Book of the Nizhny Novgorod region, obtained from various botanical gardens: Stipa capillata L. (5 samples), S. dasyphylla (Lindem.) Trautv. (2 samples), S. lessingiana Trin. et Rupr. (3 samples), S. pennata L. (2 samples), S. pulcherrima K. Koch (2 samples), S. sareptana A. K. Becker (2 samples), S. tirsa Steven. (2 samples). For each sample, the weight of 1000 seeds, their average dimensions (length, width, ratio of width and length) and the percentage of completed seeds were determined. Seeds were weighed and measured in flakes (regardless of completion, as they come from other orchards, without awns) and cleaned, completed grains. Samples were identified, the species affiliation of which is doubtful, and which, after growing and flowering, must be identified more accurately. The data can be used to compare the quality of seeds from different origins, to reject questionable samples, or to decide whether they should be examined further.
Uczeń z doświadczeniem migracji na lekcji języka angielskiego: wyzwania i rozwiązania
Authors: Rokita-Jaśkow Joanna 
Published: August 2022

The increasing number of migrant learners in Polish schools poses a new challenge not only for teachers of the language of school education, i.e. Polish, but also for teachers of other subjects, including English. Depending on the migrant learner’s country of origin, English may be his/her foreign, third (or additional) or even first language. This situation increases the heterogeneity of the language group and raises new challenges, which according to Ruiz’s (1984) conceptualization could be approached by the teacher either as a threat to the monolingual policy in the classroom, or as a resource that has the potential to enrich foreign language lessons by developing plurilingual and intercultural competences. On the basis of available research (Rokita-Jaśkow, 2019, 2021), the article presents the challenges teachers face along with suggestions for teaching solutions.
Przygotowanie uczniów do międzynarodowych certyfikatów językowych Fit in Deutsch 1 i 2 jako sposób na wykorzystanie potencjału ucznia zdolnego w rozwijaniu kompetencji językowej na poziomie A1/A2
Authors: Gierzyńska Marta 
Published: August 2022

This article is devoted to the issue of special educational needs in the context of working with a gifted learner, with particular linguistic abilities. Satisfying the needs of such children and providing them with opportunities for integral development of linguistic competence demands a different educational approach – similar to the situation when working with students with some limitations in their learning processes. The approach taken reflects the concepts and definitions of abilities presented in this article. The analysis of those elements suggests ways of identifying gifted learners and, as the next step, also offers certain educational solutions which can easily be applied in teaching. One such way can be preparing children and teenagers for international language certificates in German – Fit in Deutsch 1 and 2 as a form of extra-curricular activities. These certificates are at the A1/A2 level of language skills according to the Common European Framework of Reference for Languages (CEFR). As they are aimed at young people aged 10–16, it is possible to include primary school students in preparation for them, which in turn allows the learners to develop language skills and linguistic interests at the second stage of education. This article serves as a general overview and should not be taken as an empirical research.

Published: August 2022

Abstract

In vitro thrombogenicity tests for rotary blood pumps (RBPs) could benefit from assessing coagulation kinematics, as RBP design improves. In this feasibility study, we investigated if the method of thromboelastometry (TEM) is able to assess coagulation kinematics under the in vitro conditions of RBP tests. We conducted in vitro thrombogenicity tests (n=4) by placing Deltastream® DP3 pumps into test loops that were filled with 150 mL of slightly anti-coagulated porcine blood, adjusted to an activated clotting time (ACT) well below clinically recommended levels. Blood samples were taken at certain time points during the experiment until a continuous decrease in pump flow indicated major thrombus formation. Blood samples were analyzed for ACT, platelet count (PLT), and several TEM parameters. While visible thrombus formation was observed in three pumps, ACT indicated an ongoing activation of coagulation, PLT might have indicated platelet consumption. Unexpectedly, most TEM results gave no clear indications. Nonetheless, TEM clotting time obtained by non-anticoagulated and chemically non-activated whole blood (HEPNATEM-CT) appeared to be more sensitive for the activation of coagulation in vitro than ACT, which might be of interest for future pump tests. However, more research regarding standardization of thrombogenicity pump tests is urgently required.

Abstract
Micro-data on robots have been very sparse in Germany so far. Consequently, a dedicated section has been introduced in the IAB Establishment Panel 2019 that includes questions on the number and type of robots used. This article describes the background and development of the survey questions, provides information on the quality of the data, possible checks and steps of data preparation. The resulting data is aggregated on industry level and compared with the frequently used robot data by the International Federation of Robotics (IFR) which contains robot supplier information on aggregate robot stocks and deliveries.
