CO2 sorption properties of selected lithotypes of lignite from Polish deposits

Sorption studies, to determine the CO 2 sorption capacity of coal, were carried out using eight ortho-lignite samples of different lithotypes, to investigate the possibility of CO 2 storage in lignite deposits. Equations determining a number of parameters and indicators used to delineate the experimental data and to differentiate the samples examined include: Langmuir isotherms; the Dubinin-Radushkevich (DR) equation that describes the theory of volume filling of micropores; and the Brunauer, Emmett and Teller (BET) equation used to calculate the volume and surface area of a monolayer. The results obtained were compared with the petrographic composition and ultimate and proximate analysis of lignite. There is a large correlation between sorption and petrographic composition, a positive impact of the Gelification Index on the sorption process and a clear relationship between the sorption (Langmuir and DR) and ash content. The best CO 2 sorption properties were found for xylo-detritic and detro-xylitic lignites. Based on the tests carried out, a preliminary assessment of the suitability of lignite for CO 2 storage can be made.
Attachment and social support matters: a longitudinal moderated mediation on the link between maternal depression and maternal behaviours in at-risk adolescent mothers

ABSTRACT Adolescent motherhood tends to occur among vulnerable backgrounds, with increased environmental stressors which might jeopardize the quality of mother-infant interaction. One important factor affecting mother-infant interactions is mothers’ depressive symptoms. However, dispositional (e.g. attachment orientation) as well as external characteristics (e.g. social support) might affect this relation. This study examined longitudinally the effects of postpartum depression on maternal behaviours and explored the role played by social support and attachment orientation on this link in a sample of 35 low-income Brazilian adolescent mothers of infants 12 months old. Self-reported maternal depression and social support scales were answered by mothers and maternal behaviours were videotaped and coded at 6 and 12 months postpartum. Self-reported attachment was obtained at 12 months postpartum. Perceptions of social support mediated the association between mothers’ depression and mothers’ positive behaviours only for those with higher levels of attachment anxiety. Findings could be helpful to intervention programmes targeting adolescent mothers to promote the quality of interaction.

The overall A/T content in the plastome of M. peltatus is 64.02%. The complete plastome sequence of M. peltatus will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Euphorbiaceae.
Mycobacterium tuberculosis Modulates the Metabolism of Alternatively Activated Macrophages to Promote Foam Cell Formation and Intracellular Survival

The ability of Mycobacterium tuberculosis (Mtb) to persist inside host cells relies on metabolic adaptation, like the accumulation of lipid bodies (LBs) in the so-called foamy macrophages (FM). Indeed, FM are favorable to Mtb. The activation state of macrophages is tightly associated to different metabolic pathways, such as lipid metabolism, but whether differentiation towards FM differs between the macrophage activation profiles remains unclear. Here, we aimed to elucidate if distinct macrophage activation states exposed to a tuberculosis-associated microenvironment can accumulate LBs, and its impact on the control of infection. We showed that signal transducer and activator of transcription 6 (STAT6) activation in interleukin (IL)-4-activated human macrophages (M(IL-4)) prevents FM formation induced by pleural effusion from patients with tuberculosis. In these cells, LBs are disrupted by lipolysis, and the released fatty acids enter the β-oxidation (FAO) pathway fueling the generation of ATP in mitochondria. We demonstrated that inhibition of the lipolytic activity or of the FAO drives M(IL-4) macrophages into FM. Also, exhibiting a predominant FAO metabolism, mouse alveolar macrophages are less prone to become FM compared to bone marrow derived-macrophages. Upon Mtb infection, M(IL-4) macrophages are metabolically re-programmed towards the aerobic glycolytic pathway and evolve towards a foamy phenotype, which could be prevented by FAO activation or inhibition of the hypoxia-inducible factor 1-alpha (HIF-1α)-induced glycolytic pathway. In conclusion, our results demonstrate a role for STAT6-driven FAO in preventing FM differentiation, and reveal an extraordinary capacity by Mtb to rewire metabolic pathways in human macrophages and induce the favorable FM. IMPORTANCE Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb). While its treatment was already standardized, TB remains one of the top 10 death causes worldwide. A major problem is the efficient adaptation of Mtb to the macrophage intracellular milieu, which includes deregulation of the lipid metabolism leading to the formation of foamy macrophages (FM) which are favorable to Mtb. A critical aspect of our work is the use of tuberculous pleural effusions (TB-PE) — human-derived biological fluid capable of mimicking the complex microenvironment of the lung cavity upon Mtb infection — to study the FM metabolic modulation. We revealed how the STAT6 transcription factor prevents FM formation induced by PE-TB, and how Mtb counteracts it by activating another transcription factor, HIF-1α, to re-establish FM. This study provides key insights in host lipid metabolism, macrophage biology and pathogen subversion strategies, to be exploited for prevention and therapeutic purposes in infectious diseases.
Control of endoplasmic reticulum membrane biogenesis by regulators of lipid metabolism

ABSTRACT Cells dynamically adapt organelle size to current physiological demand. Organelle growth and proliferation require membrane biogenesis and need to be coordinated with lipid metabolism. The endoplasmic reticulum (ER) can undergo massive expansion but the mechanisms that govern ER membrane biogenesis are unclear. Here, we genetically screen for factors mediating ER expansion in budding yeast and identify lipid synthesis enzymes and the ER transmembrane protein Ice2 as strong hits. Ice2 inhibits the conserved phosphatidic acid phosphatase Pah1 by opposing the activity of the Nem1-Spo7 complex. This regulation counteracts the production of storage lipids and directs lipid metabolism towards membrane biogenesis. Furthermore, Ice2 acts in concert with the transcriptional control of lipid synthesis enzymes and cooperates with the unfolded protein response to maintain ER homeostasis. These findings establish the regulation of the lipin ortholog Pah1 as a key determinant of ER membrane biogenesis.
Using Fine-grained Emotion Computing Model to Analyze the Using Fine-grained Emotion Computing Model to Analyze the Interactions between Netizens’ Sentiments and Stock Returns Interactions between Netizens’ Sentiments and Stock Returns

: From the perspective of behavioural finance, this paper combines the fine-grained sentiment calculation with the stock market econometric model to explore the interactions between netizens’ sentiments and stock returns, analyze the differences in the influences of various emotions expressed by netizens on the stock market. First, it constructs a sentiment dictionary for the financial field; then, it calculates the emotion values contained in the text corpus, and constructs a textual sentiment classifier based on the recurrent neural network, calculates the emotion value and establishes the daily netizen sentiment index; and finally, it builds an econometric model to study the interactions between the netizen sentiment index and the stock returns. The results show that this model improves the accuracy of sentiment classification, reduces the number of iterations and saves computing resources; and that the netizen sentiment index, especially, “disgust” and “like”, has significant effects on the stock price changes and transaction volumes, while on the other hand, the listed company’s stock returns data has no reverse effect on the netizen sentiment index.
THE ROLE OF SPIRITUALITY AND RELIGIOUSNESS IN AIDING RECOVERY FROM ALCOHOL AND OTHER DRUG PROBLEMS: AN INVESTIGATION IN A NATIONAL U.S. SAMPLE.

Background More Americans than ever before are identifying as "spiritual but not religious". Both spirituality and religiousness (S/R) are of interest in the addiction field as they are related to alcohol and other drug (AOD) problems and are central to some recovery pathways. Yet, little is known overall about S/R identification among people in recovery, the role these play in aiding recovery, and whether they play more or less of a role for certain sub-groups (e.g., men/women, different races/ethnicities; those with treatment or 12-step histories). Method Nationally representative cross-sectional sample of US adults (N=39,809) screening positive to the question, "Did you use to have a problem with alcohol or drugs but no longer do? " (final weighted sample n= 2,002). Weighted Chi-Square and Poisson-distributed generalized linear mixed models tested for differences in S/R and for differences across subgroups on extent of: 1) religious, and, 2) spiritual, identification, and the extent to which these had aided recovery. Results Participants reported being mostly moderately spiritual and religious, and that, overall, religion had not helped them overcome their AOD problem. In contrast, spirituality was reported as either not helping at all, or having made all the difference. Substantial differences were observed by race-ethnicity across both spirituality and religiousness, and to a lesser degree between men and women. Black Americans reported substantially more S/R than Whites and that these often made all the difference in their recovery. The exact opposite trend was observed for White and Hispanic Americans. Prior professional treatment and 12-step mutual-aid use were both related to greater spirituality, but not religiousness. Conclusion Overall, spirituality but not religion, appears to play a role in aiding recovery particularly among those with prior treatment or 12-step histories, but women and men, and racial-ethnic groups in particular, differ strikingly in their religious and spiritual identification and the role these have played in aiding recovery. These differences raise the question of the potential clinical utility of S/R in personalized treatment.
The complete chloroplast genome of the Buddleja alternifolia (Buddleiaceae), an ornamental plant

Abstract Buddleja alternifolia is China’s specialty, and scattered in northwest China. Here, we assembled and characterized the complete chloroplast (cp) genome of B. alternifolia using Illumina sequencing data for the first time. The complete cp genome was 154,280 bp in length, consisting of a pair of inverted repeats of 25,440 bp, a large single-copy (LSC) region of 85,330 bp, and a small single-copy (SSC) region of 18,070 bp. The genome encoded 115 unique genes, including 80 protein-coding genes, 31 tRNA genes, and four rRNA genes. Phylogenetic analysis based on 16 complete cp genome sequences indicated that B. alternifolia is closely related to Buddleja colvilei.
Initial Stages of Metal Films Growth on a SiO2-Cristobalite Surface

Using the density functional theory approach and pseudopotentials we studied energetics and electron structures of metal layers (Al, Cu, Ni, and Cr) deposited on a cristobalite surface. We have found that the properties of the first adsorbed layers decide by interaction of metal atoms with oxygen atoms of a substrate surface. Aluminum as an easily oxidized metal, is characterized by the high adhesion, it is followed by nickel and chromium, and copper closes the studied group of metals. Further plating is characterized by significant reduction of binding energy; the properties of films tend to properties of bulk metals.
Environmentally triggered evolutionary cascade across trophic levels in an experimental phage-bacteria-insect system

Environmental changes can cause strong cascading effects in species communities due to altered biological interactions between species (Zarnetske et al., 2012). Highly specialized interactions arising from the co-evolution of hosts and parasites, such as bacteria and phages, and short generation times of these species could rapidly lead to considerable evolutionary changes in their biotic interactions (Kerr, 2012; Buck and Ripple, 2017), with potential large-scale ramifications to other trophic levels. Here we report experimental evidence of cascading environmental effects across trophic levels in an experimental system where phage-bacteria coevolution in an abiotically altered environment cascaded on bacterial virulence in an insect host. We found that the lytic cycle of the temperate phage KPS20 induced at low temperatures led to selection in the bacterial host Serratia marcescens that tempered the likelihood of triggering the phage’s lytic cycle. These changes in S. marcescens concomitantly attenuated its virulence in an insect host, Galleria mellonella. In addition, our data suggests that this effect is mediated by mutations and epigenetic modifications of bacterial genes moderating the onset of the temperate phage’s lytic cycle. Given the abundance of temperate phages in bacterial genomes (Canchaya et al., 2003), the sensitivity of the onset of their lytic cycle to environmental conditions (Howard-Varona et al., 2017), and the predominance of environmental change due to climate change, our results warrants attention as a cautionary example of the dangers of predicting environmental effects on species without considering complex biotic interactions.
A comparison of extreme gradient boosting, SARIMA, exponential smoothing, and neural network models for forecasting rainfall data

Extreme gradient boosting, is a combination of gradient descent and boosting that can be used to build an optimal model for time series data. This method was used to forecast the rainfall data in city of Bandung for period 2018-2019 and compared to Seasonal Autoregressive Integrated Moving Average (SARIMA) exponential smoothing, and artificial neural network which were used as benchmarks. Data used in this study were monthly rainfall from 2000 through 2017. The extreme gradient boosting had the lowest mean absolute deviance, root mean squared error deviance, and mean absolute percentage error. This indicates the extreme gradient boosting model performed better than the SARIMA, exponential smoothing, and neural network. Based on the extreme gradient boosting model, it is concluded that the highest rainfall will occur between September 2018 and May as a rainy season in Bandung, and the lowest rainfall will occur between June and August as a dry season.
Effects of Particulate and Fibrous Carbon Filler Combinations on the Tribological Behavior of a Polyacetal Composite under Water Lubrication

This study focused on the effects of combinations of fillers comprising particulate and fibrous carbon materials on the tribological behaviors of a polyacetal (POM) composite under water lubrication. The filler materials were rice bran ceramics (RBC) particles and carbon fibers (CFs). Friction tests were conducted using a ring-on-disk-type friction tester under water lubrication and the ring specimen was an austenitic-stainless-steel ring. The RBC/CF composite exhibited the lowest friction coefficients (0.10–0.14) compared with the other composites, including pure POM, irrespective of the number of friction cycles. The CF composite produced a low friction coefficient during the initial stage of friction but then increased to 0.25. The wear volume of the RBC/CF composite was the smallest, irrespective of the number of friction cycles. The specific wear rate of the RBC/CF composite decreased over the wear periods, indicating a low value of 10 mm/N·m at the end of the long-term friction cycles. Scanning electron microscopy observations and measurements of the surface geometries indicated that the combination of RBC particles and CFs produced the low friction and low wear because the RBC particles complemented the poor wear resistance of the CFs.
Needs analysis to development of biology module based on problem solving at topics of respiratory and excretory systemf to student of seniorhigh school grade XI

Biology learning in general should consider the scientific process, where students must be able to build their own knowledge actively through meaningful learning processes. One way is to improve students ability to solve problems in accordance with one of the goals of applying the 2013 curriculum. This ability can be created with the help of teachers as facilitators and other facilities such as teaching materials. In high school students of class XI there is no official curriculum book 2013 issued minister of education. Books used by students in schools are private publications that have not been proven valid, practical and effective. Therefore, the researcher did a requirement analysis to 30 students of grade XI IPA in SMAN 7 Padang with the aim to see the need to develop biology materials based on problem solving about respiratory system and excretory system in high school student of SMA XI. Data collection using observation techniques, questionnaires and interviews with data analysis include front end analysis, students, needs and curriculum.

Based on this it is found that the need to develop a biology-based materials problem solving about respiratory system and excretory system material in high school students XI.
A two‐level study of predictors of private tutoring attendance at the beginning of secondary schooling in Germany: The role of individual learning support in the classroom

More and more students attend private supplementary tutoring to improve their academic achievement. Private tutoring might be understood as a reaction to insufficient instructional quality in school, especially regarding individual support. However, it might also be possible that parents generally see insufficient grades as an indicator of lacking support and engage a tutor in hopes of improvement or to enhance a competitive edge for their children. So far, the relationship between tutoring attendance and perceived individual learning support during classroom lessons has not been tested. We used multilevel analyses based on N = 2,842 students in 102 Grade 5 classrooms at German academic track schools to test for a relationship between private tutoring in several subjects and students’ shared perception of the instructional quality in these subjects. On the individual level, we controlled for typical predictors of private tutoring such as academic achievement and family income, as well as for additional variables such as working behaviour and parental homework assistance. In classrooms with more individual support, students were less likely to start private tutoring in English. However, we did not find comparable relationships for tutoring in mathematics and German. Therefore, school principals and educational policy-makers should monitor the incidence of private tutoring and consider within-school structured tutoring programmes as an effective measure to improve academic achievement and to meet parents’ desire for individualised instruction.
