Authors: Biały Halina 
Published: February 2021

Artykuł przedstawia rys historyczny i różne aspekty działalności Centralnego Towarzystwa Rolniczego (CTR) w Królestwie Polskim. Oficjalnie zainaugurowało działalność 11 III 1907 r. wzorem wcześniejszych zrzeszeń rolniczych, podejmując działania mające na celu modernizację rolnictwa i wsi w istniejących politycznych, społecznych oraz gospodarczych realiach zaboru rosyjskiego. Uzyskawszy rządowe pozwolenie na rozpoczęcie działalności, CTR prowadziło politykę gospodarczą oddziałującą na rynek towarowy i rynek pracy. W jej ramach funkcjonowały wydziały: Kółek Rolniczych, Społeczno-Ekonomiczny, Rolniczy, Hodowlany i Naukowo-Dydaktyczny, które realizowały zadania, mając na uwadze unowocześnienie i usprawnienie polskiego rolnictwa. Działalność przejawiała się m.in. w organizacji jarmarków, na których prezentowano np. inwentarz żywy czy maszyny rolnicze, ponadto organizowano odczyty, kursy, wycieczki rolnicze, podejmowano starania o szkolnictwo rolnicze na dobrym poziomie oraz propagowano prasę i książki na temat rolnictwa. Prowadzono też stacje i pola doświadczalne. Po zakończeniu I wojny światowej CTR skoncentrowało się na naprawie szkód wyrządzonych przez działania wojenne. Towarzystwo chwalebnie zapisało się w dziejach polskiego rolnictwa w aspekcie jego modernizacji i integracji środowiska związanego z polską wsią.

Abstract
Access to safely managed drinking water (SMDW) remains a global challenge affecting 2.2 billion people [1,2]. Atmospheric Water Harvesting (AWH) can accelerate progress through decentralized production of liquid water from air [3]. A solar-driven device capable of active daytime operation can unlock design advantages through continuous cycling [4,5] and could be sized to household scale, though lower daytime humidity raises concerns about widespread suitability [6–8]. However, no methodological analysis has been conducted to characterize the global potential of daytime AWH [9] despite the favorable climatic conditions of low and middle-income countries (LMICs) in the tropical regions where two-thirds of people without SMDW services live [2]. Here we present a computing toolset built with Google Earth Engine to calculate the global potential of solar-driven AWH operating in continuous mode. By mapping time-averaged, contemporaneous occurrence of incident solar energy and available water vapor using a climate timeseries and official estimates of the geographic distribution of water service globally, we show that a significant portion of the world’s population without SMDW reside in a climate suitable for a device to serve their daily drinking water requirements. A device functional to relative humidity 30% can serve 1 billion in need by running 4-5 h/day above 600 W/m2, operational parameters which have been approached experimentally in recent prototypes using novel sorbents [10–17]. Steep gradients of AWH suitability in the Sahel of Africa indicate high sensitivity of design criteria to market serviceability. This global assessment of solar-driven AWH, unlocked by accessible high-performance geospatial computing [18] and climate data assimilated at high spatio-temporal resolution, can enable household-scale device innovation and accelerate the progress towards global goals.

Abstract
The structure and properties of metal-hydrides at extreme conditions is key to the understanding of hydrogen-storage technologies, high-temperature superconductivity, and the dynamics of planetary cores. Here we investigate the phase relations and magnetic properties of iron hydrides, including two novel FeHx compounds, up to 63 GPa and 1800 K by Synchrotron Mössbauer Source spectroscopy and single-crystal X-ray diffraction. We observe the formation of a novel monoclinic iron hydride phase Fe2H∼3 at 63 GPa and 1000 K, which breaks down to a stoichiometric hexagonal closed packed FeH phase upon decompression below 52 GPa at 300 K. The long-range magnetic order in the two newly-synthetized phases persists to higher pressures compared to the well-known double hexagonal closed packed and face-centered cubic phases of FeH. The formation of magnetic Fe-H phases with high hydrogen concentration may influence the magnetic behavior of planetary metallic cores.

Abstract
Background：A high-quality protein substitute, Hermetia illucens (Black soldier fly) larvae powder is rich in protein, fat, amino acid, calcium, and other substances. Due to the relatively few studies on the feeding of weaned piglets, in the present study, we replaced part or all of the fish meal with a relevant proportion of Hermetia illucens larvae powder in the feed to study its effect on weaned piglets. A total of forty-eight young female weaned piglets (Duroc ´ Landrace ´ Large White) with initial body weights (BW) 7.68 ± 0.26 kg, were randomly divided into three groups, each group had eight replicates, two pigs per replicate. Three groups containing different proportions of Hermetia illucens larvae powder (0, 4%, and 8%) were referred to as C, HI4, and HI8. We designed a 28-day feeding experiment, collecting blood and feces, thereafter inducing the piglets with oral gavage of ETEC K88 and recording diarrhea on day 29 of the experiment. Four piglets in each group were selected to collect serum, colon contents, intestinal tissue, and jejunum, ileum, colon mucosa samples.Results：The growth performance of weaned piglets remained unaffected on supplementing feed with Hermetia illucens. Compared with C+K88 group, the diarrhea rate was found to be attenuated for the Hermetia illucens supplemented group. Severe damage was evident in the case of the ileum villi of the C+K88 group, whereas improved integrity was demonstrated by the ileum villi of the HI4+K88 and HI8+K88 groups. Significantly increased expressions of the anti-inflammatory factor IL-10 in the intestinal mucosa (P < 0.05) and the tight junction proteins Occludin and Claudin-3 (P < 0.05) and reduced expression of the pro-inflammatory factor TNF-α (P < 0.05) were reflected in the HI4+K88 and HI8+K88 groups as compared to the C+K88 group. The activity of antioxidant enzymes CAT and POD (P < 0.05) also revealed an effective increase in the Hermetia illucens supplemented groups than the control. The results of immunoblotting also validated that the same ETEC K88 treatment of weaned piglets enhanced the expression of tight junction protein in the intestinal mucosa of the Hermetia illucens addition group (P < 0.05) and the integrity of the intestinal barrier was also better maintained. The experimental results affirmed that Hermetia illucens larvae powder could partially or completely replace fish meal, increase the content of Lactobacillus, reduce the content of Streptococcus, improve the body’s disease resistance, and improve intestinal health.Conclusions：ETEC-induced diarrhea will be reduced by the diet of weaned piglets containing Hermetia illucens larvae, ameliorating the immune performance of pigs. The present research provides a new perspective for insect meal as a sustainable protein source for pig feed.

Published: February 2021

Abstract
Aberrant alternative splicing (AS) events serve as prognostic indicators in a large number of malignancies, whereas comprehensive analysis of prognostic AS in gastric cancer (GC) has not yet been understood. To identify prognostic AS events and clarify the function of the splicing variants in GC. RNA-Seq data, clinical information and percent spliced in (PSI) values were available in the cancer genome atlas (TCGA) and TCGA SpliceSeq data portal. A three-step regression method was conducted to screen prognostic AS events and construct multi-AS-based signatures. The associations between prognostic AS events and splicing factors were also investigated. We identified a total of 1318 survival related AS events in GC, Parent genes of which were implicated in numerous oncogenic pathways. The final prognostic signatures stratified by seven types of AS events or not stratified performed well in risk prediction for GC patients. Moreover, five signatures base on AA, AD, AT, ES and RI events function as independent prognostic indicators after multivariate adjustment of clinicalpathological variables. Splicing network also showed marked correlation between the expression of splicing factors and PSI value of AS events in GC patients. The AS derived signatures allow to predict GC prognosis and might serve as potential therapeutic target for GC.

Abstract
Uniform periodic microstructures formation over large areas is generally challenging in Direct Laser Interference Patterning (DLIP) due to the Gaussian laser beam intensity distribution inherent to most commercial laser sources. In this work, a diffractive fundamental beam-mode shaper (FBS) element is implemented in a four-beam DLIP optical setup to generate a square-shaped top-hat intensity distribution in the interference volume. The interference patterns produced by a standard configuration and the developed setup are measured and compared. In particular, the impact of both laser intensity distributions on process throughput as well as fill-factor is investigated by measuring the resulting microstructure height with height error over the structured surface. It is demonstrated that by utilizing top-hat-shaped interference patterns, it is possible to produce on average 44.8 % deeper structures with up to 60 % higher homogeneity at the same throughput. Moreover, the presented approach allows the production of microstructures with comparable height and homogeneity compared to the Gaussian intensity distribution with increased throughput of 53%.

Abstract
Background: Poor maternal mental health is a major public health concern since it adversely impacts both maternal and child health outcomes. This study aimed to document the barriers to utilizing perinatal mental health services in Karnataka, India, and to determine its relationship with risk factors of poor maternal mental health in this context. Methods: Qualitative research methods using in-depth interviews were conducted on twenty-one local stakeholders who represented health service providers in various capacities: mental health specialists (n = 4), gynaecologists (n = 2), government officials from the Department of Health and Family Welfare (n = 2), and Department of Women and Child Development (n = 2), senior state consultant to United Nations Children’s Fund (n = 1), and frontline workers (n = 10). Data were analysed using a thematic framework analysis approach. Results: We identified multiple barriers to service utilization operating at the levels of the health system, community, family, and the individual. Health-system level barriers included lack of a universal screening mechanism, poor infrastructure, poor training of frontline workers on mental health issues, and inadequate time for counselling and treatment. Community-level barriers included stigma and misconceptions, leading to a lack of social support. Family and individual level barriers included the financial burden of availing services, lack of family and partner support, and lack of empowerment and motivation in the woman to seek services. Family and individual level barriers interacted with risk factors of poor maternal mental health. Based on this evidence and drawing from the literature, we propose a contextualised, stepped-care model for universal screening, detection, referral, and treatment of women with perinatal mental health conditions for Karnataka that is integrated with the reproductive, maternal, and child health (RMNCH) program in primary care settings. Conclusions: The framework developed in this study suggests that addressing the identified barriers would potentially increase uptake of available services, create awareness about and demand for high-quality mental health services, reduce the risk factors of poor maternal mental health, and eventually improve our understanding of its true burden in the state of Karnataka. This is essential for proper implementation, monitoring, and evaluation of programs relevant to perinatal mental health.

Abstract
Background: Xuefu Zhuyu decoction is a traditional Chinese formula composed of eleven herbs, which has the effect of promoting blood circulation and removing blood stasis. In this study, the anti-inflammatory mechanisms of Xuefu Zhuyu decoction in the treatment of atherosclerosis were studied utilizing network pharmacology, data mining, microarray data differences analysis and molecular docking.Methods: Analyzing data from the TCMSP, the effective components and key targets of Xuefu Zhuyu decoction were screened out. Atherosclerosis-related genes were extracted from the disease databases and determined according to differences analysis. The component-target network was constructed and gene enrichment analysis, as well as topology analysis, were carried out. Finally, the affinity between the target and the effective components was verified by molecular docking.Results: We screened 186 effective components of Xuefu Zhuyu decoction from TCMSP and obtained 126 targets. Through searching the disease databases and analyzing the results of differences analysis, two hundred and one atherosclerosis-related genes were obtained. After constructing the component-target network, it was found that Xuefu Zhuyu decoction played an anti-atherosclerotic role by acting on 21 targets. The results of enrichment analysis suggested that 21 key targets were mainly enriched in biological processes such as leukocyte adhesion and endothelial cell proliferation. The results of molecular docking showed that the key components of Xuefu Zhuyu decoction, have a good affinity with IL-6 and VEGFA.Conclusions: Our bioinformatics analyses suggest that Xuefu Zhuyu decoction plays an anti-atherosclerotic role by regulating biological processes such as leukocyte adhesion and endothelial cell proliferation. This study provides a theoretical basis for the further study of the indications of Xuefu Zhuyu decoction and the development of anti-atherosclerotic drugs.

Abstract
The red-leaved poplar cultivars ‘Quanhong’ and ‘Xuanhong’ are bud mutations of Populus deltoides cv. ‘Zhonglin 2025’. These cultivars are valued for their beautiful shape, lack of flying catkins, and ornamental leaf colors. However, the understanding of the molecular mechanism of anthocyanin accumulation in the leaves of red-leaved poplars is still unclear. Here, we profiled the changes of pigment content, transcriptome and proteome expression in the leaves of three poplar cultivars and the results showed that the ratios of anthocyanin to total chlorophyll in both red-leaved poplars were higher than that in ‘Zhonglin 2025’, indicating that the anthocyanin was highly accumulated in the leaves of red-leaved poplars. Based on the results of integrated transcriptome and proteome analysis, 15 and 11 differentially expressed genes/proteins involved in anthocyanin synthesis were screened in ‘Quanhong’ and ‘Xuanhong’, respectively, including the CHS, F3H, and DFR genes. Among the 120 transcription factors, 3 (HY5, HYH, and TTG2), may be directly involved in the regulation of anthocyanin synthesis in both red-leaved poplars. This study screens the candidate genes involved in anthocyanin accumulation in the leaves of red-leaved poplars and lays a foundation for further exploring the molecular mechanism of leaf red coloration in red-leaved poplars.

Published: February 2021

Abstract
The COVID-19 is still a huge challenge that seriously threatens public health globally. Previous studies focused on the influence of air pollutants and probable meteorological parameters on confirmed COVID-19 infections via epidemiological methods. Whereas, the findings of relations between possible variables and COVID-19 incidences using geographical perspective were scarce. In the present study, data concerning confirmed COVID-19 cases and possible affecting factors were collected for 325 cities across China up to May 27, 2020. The Geographical Weighted Regression (GWR) model was introduced to explore the impact of probable determinants on confirmed COVID-19 incidences. Some results were obtained. AQI, PM2.5, and PM10 demonstrated significantly positive impacts on COVID-19 during the most study period with the majority lag group (P＜0.05). Nevertheless, the relation of temperature with COVID-19 was significantly negative (P＜0.05). Especially, CO exhibited a negative effect on COVID-19 in most study period with the majority lag group. The impacts of each possible determinant on COVID-19 represented significantly spatial heterogeneity. The obvious influence of the majority of possible factors on COVID-19 was mainly detected during the after lockdown period with the lag 21 group. Although the COVID-19 spreading has been effectively controlled by tough measures taken by the Chinese government, the study findings remind us to address the air pollution issues persistently for protecting human health.

Published: February 2021

Abstract
Sheet metal forming processes are very common manufacturing and leading processes in automotive and aerospace industries. Flexforming is one of the sheet metal forming processes which is preferable due to its flexible manufacturing capabilities and its ability to produce multiple parts simultaneously. Convex contoured shaped parts are very much used in aerospace structures which are mostly produced by flexforming. Wrinkling is a characteristic defect for those kinds of parts. Prediction of wrinkling before manufacturing is highly crucial in order to reduce scrap rates, labor time, and other unexpected costs. In this research work, extensive amounts of experiments are conducted on flexforming press, and the process parameters such as material condition, contour radius, flange length, and material thickness which induce wrinkling are investigated in detail. Results have shown that sheet thickness is the most effective parameter, and as the sheet thickness is increased, wrinkling tendency is reduced extensively. Besides, increasing convex contour radius decreases wrinkling occurrence. Experimental findings are then used to generate wrinkling limit diagrams in which safety and failure zones are specified for different material conditions and sheet thicknesses. The developed diagrams might help to designer who can design defect free parts, reduce scrap rates, and reduce production costs significantly.

Abstract
Objectives: To evaluate national epidemiologic data on infants treated for patent ductus arteriosus (PDA) in Korea and analyze outcomes associated with different PDA treatments. Study Design: We retrospectively evaluated data on 12,336 patients diagnosed with PDA (International Classification of Diseases-10 code: Q250) between 2015 and 2018 from the Health Insurance Review and Assessment database. Among them, 1,623 patients underwent surgical ligation (code: O1671). We used birth certificate data from Statistics Korea to estimate the prevalence, diagnosis, and treatment of PDA. Results: The prevalence of infants with PDA was 81 infants per 10,000 live births and 45.2% in very low birth weight (VLBW) infants, which increased from 2015 to 2018. PDA ligation was performed in 2571 infants and 22% VLBW infants. Medical treatment was administered to 4202 infants, which decreased significantly, especially in VLBW infants (62% to 53%). The proportion of treatment was as follows: conservative treatment (53.1%), intravenous ibuprofen (24.4%), surgery (20.4%), and oral ibuprofen (10.7%); that among 4,854 VLBW infants was as follows: intravenous ibuprofen (46.3%), conservative treatment (33.2%), surgery (22.2%), and oral ibuprofen (14.2%). Surgical treatment had a significantly higher risk (odds ratio 1.36) of mortality than conservative treatment. Surgical and/or medical treatments were associated with a higher risk of morbidity.Conclusion: Recently, increased use of conservative management of PDA has contributed to improved neonatal outcomes in VLBW infants. Select patients may still benefit from surgical ligation following careful consideration.
