Diatom of the Bacillariophyceae Class in Thermophilic Microbial Mats Present in Sulphurous Hot Springs and their Possible Biotechnological Application

The diversity of diatoms in the hot springs of the Comanjilla geothermal zone in northern Guanajuato, Mexico was studied. Hot springs are extreme ecosystems that, despite having high temperatures, constitute an environment for many thermophilic microorganisms (bacteria, cyanobacteria, and diatoms). The thermal water studied is classified as hyperthermal water (45°C to 100°C), of deep origin, and with low mineralization, are of type sulfuric sodium chloride, since the dissolved content of hydrogen sulfide (H2S) is found in concentrations higher than 1mg/L, and its smell is similar to the one of rotten eggs, presents a pH of 7.6 to 9.1 that represents neutrophilic to alkaliphilic environments, with a variable electrical conductivity (EC) (658-698 µs / cm) and total dissolved solids (TDS) (314-24 ppm). In the same way, these hot springs present microbial mats that consist of several stratified layers of green and orange color of 100 cm2, each one, which are dominated by specific types of microorganisms such as bacteria, cyanobacteria, but mainly diatoms, the latter were studied applying the scanning electron microscope and the optical microscope. The morphological characteristics observed in the optical microscope and in the scanning electron microscopy indicate the presence of diatoms of the Bacillariophyceae class, represented by Sellaphora disjuncta (55%), Achnanthes brevipes var. intermedia (45%). This diatom present in thermophilic microbial mats in the sulphurous geothermal zone of Comanjilla represents: a) the first report of said microorganisms in the study area and Mexico; b) an ecosystem of great interest from the biotechnological and industrial point of view; c) an important taxon in terms of diversity and technology; d) an applications in biofuels, environmental monitoring, wastewater treatment, manufacture of fertilizers, production of secondary metabolites, medical compounds, energy sources and food industry and within nanotechnology. It is important to mention that the physical and chemical characteristics of thermal water such as temperature, pH, dissolved solids, electrical conductivity, hardness, alkalinity and silica concentrations, were the major environmental factors influencing the distribution of diatoms in sulphurous hot springs.
Response Characteristics Modeling of Efficiency and NO_x Emission for Power Station Boiler

In order to improve the efficiency and to reduce NOx emission in combustion, a mixed model of the coal-fired boiler was studied by using kernel principle component analysis (KPCA), e-support vector regression (e-SVR) and function-type model. In the process of modeling, principal components of the original inputs were extracted using KPCA for eliminating the nonlinear relationship and strong-coupling among original inputs, and then the 5-fold cross validation method was used to search the optimal free parameters of the model and select the optimal number of principle components. Finally, the mixed model was compared with back propagation neural-networks(BPNN) and e-SVR model respectively; it is shown that the mixed response characteristics model exceeds the other two models and has powerful prediction precision and generalization.
Visualization of 3-D Field of Explosion

In order to visualize the 3-D field of explosion and describe the complex physical phenomena of explosion, the 3-D data resulting from numerical simulation by 3-D multi-material in cell (MMIC), and the application of volume visualization is explored, based on the characteristics of explosion and shock. Based on this, a visualization system for 3-D explosion--ViSC3D is designed. Approaches for the visualization of 3-D field of explosion are presented. The algorithm and the functions of ViSC3D are also presented. ViSC3D is thus a useful tool to observe and analyze either the full picture or the details of a 3-D field of explosion, that are difficult to observe and analyze directly. With ViSC3D, the field of explosion between the hill slopes is visualized. The cutaway views and 2-D slices are also given. The full picture and partial details of 3-D field of explosion can be observed clearly. Furthermore, ViSC3D can be used to visualize other similar 3-D data fields.
Quantitative Proteomics Reveals the Role of Lysine 2-Hydroxyisobutyrylation Pathway Mediated by Tip60

Lysine 2-hydroxyisobutyrylation (Khib) is a new type of posttranslational modifications (PTMs) extensively reported on eukaryotic cell histones. It is evolutionarily conserved and participates in diverse important biological processes, such as transcription and cell metabolism. Recently, it has been demonstrated that Khib can be regulated by p300 and Tip60. Although the specific Khib substrates mediated by p300 have been revealed, how Tip60 regulates diverse cellular processes through the Khib pathway and the different roles between Tip60 and p300 in regulating Khib remain largely unknown, which prevents us from understanding how this modification executes its biological functions. In this study, we report the first Khib proteome mediated by Tip60. In total, 3502 unique Khib sites from 1050 proteins were identified. Among them, 536 Khib sites from 406 proteins were present only in Tip60 overexpressing cells and 13 Khib sites increased more than 2-fold in response to Tip60 overexpression, indicating that Tip60 significantly affected global Khib. Notably, only 5 of the 549 Tip60-targeted Khib sites overlapped with the 149 known Khib sites targeted by p300, indicating the different Khib substrate preferences of Tip60 and p300. In addition, the Khib substrates regulated by Tip60 are deeply involved in processes such as nucleic acid metabolism and translation, and some are associated with Parkinson's and Prion diseases. In summary, our research reveals the Khib substrates targeted by Tip60, which elucidates the effect of Tip60 in regulating various cellular processes through the Khib pathway, and proposes novel views into the functional mechanism of Tip60.
A Comparative Analysis of the Semantic Field of ‘deception’: A Case Study Of Russian And American Imageboard Messages

This article uses the material of anonymous Internet forums to analyse the semantic field of deception by the instrumentality of artificial neural networks. Two major imageboards were investigated: 2ch.hk and 4chan.org, being the most popular Russian and American imageboards. For the experiment an algorithm called Word2vec was used to examine 30 million word usages for either of the languages. This analysis revealed 10 words with the greatest semantic proximity to terms from semantic fields of «deception» for Russian and American English. The results showed the tendency among native Russian imageboard users to link the concept of deception with religion and spiritual sphere, while American forum users associate deception with politics and related concepts.
Ultrafast Spin‐Charge Conversion at SnBi2Te4/Co Topological Insulator Interfaces Probed by Terahertz Emission Spectroscopy

Spin‐to‐charge conversion (SCC) involving topological surface states (TSS) is one of the most promising routes for highly efficient spintronic devices for terahertz (THz) emission. Here, the THz generation generally occurs mainly via SCC consisting in efficient dynamical spin injection into spin‐locked TSS. In this work, sizable THz emission from a nanometric thick topological insulator (TI)/ferromagnetic junction—SnBi2Te4/Co—specifically designed to avoid bulk band crossing with the TSS at the Fermi level, unlike its parent material Bi2Te3 is demonstrated. THz emission time domain spectroscopy (TDS) is used to indicate the TSS contribution to the SCC by investigating the TI thickness and angular dependence of the THz emission. This work illustrates THz emission TDS as a powerful tool alongside angular resolved photoemission spectroscopy (ARPES) methods to investigate the interfacial spintronic properties of TI/ferromagnet bilayers.
Novel Flexibility Indices of Controllable Loads in Relation to EV and Rooftop PV

In order to analyze the flexibility of controllable loads in smart homes, two flexibility indices are proposed in this study. The first index, the electric vehicle (EV) flexibility index, determines the ability of any particular controllable load to avoid the EV charging intervals during its operation. The second index, the photovoltaic (PV) flexibility index, evaluates the ability of any controllable load to absorb PV power during its operation. Both these indices can be utilized by homeowners or policymakers in installing/updating PVs and controllable home appliances. Higher index values imply more flexibility and thus those devices are more beneficial for the homeowners. In order to capture different consumption patterns in different homes, five home clusters are considered in this study. In each cluster, the controllable loads are grouped into three groups based on their flexibility level and utilization purpose. The performance of the proposed method is analyzed for the two commonly used charging levels in the residential sector, i.e. level 1 and level 2. In addition, sensitivity analysis of different uncertain factors such as PV power, the arrival time of EVs, and daily mileage of EVs is also carried out. Simulation results have shown the effectiveness of the proposed method in determining the flexibility of different controllable loads with respect to EVs and PV.
Experimental analysis on cycle processes of two-phase valveless pulse detonation engine

Experimental investigations were conducted on a two-phase valveless pulse detonation engine to explore the cycle processes.Gasoline and air were formed combustible mixture and was ignited by a spark with low energy release subsequently.Multi-cycle detonation test showed that characteristic times of the two-phase valveless PDE mock-up at operating frequency from 10 to 66Hz are different from others.Pressure evolution in the detonation tube was detected through pressure histories at different points along detonation tube at low operating frequency, and some characteristic times of cycle processes was obtained from pressure history at thrust wall from 10~66Hz.Due to long ignition delay time and DDT time for two-phase PDE,additional filling process after spark discharge was found.There exists limit cycle duration,which is equal to the difference of entire cycle duration and the pre-ignition filling time.Also,for increasing operating frequency,the most important factors were analyzed.
Phytoplankton Community Structure in Highly-Mineralized Small Gypsum Karst Lake (Russia)

Gypsum karst lakes are unique water ecosystems characterized by specific habitat conditions for living organisms, including phytoplankton species, as primary producers and mediating biogeochemical cycles in the water bodies. Studies of diversity and structure of phytoplankton communities can be used to identify the specific and typical lake features and plan basin-wide monitoring. The aim of this research was to analyze the structural variables of algocenoses in the small gypsum karstic Lake Klyuchik (Middle Volga basin), atypical for the subzone of mixed coniferous and deciduous forest zone high values of water mineralization (brackish water) and low temperatures. The lake has two water areas, connected by a shallow strait (ecotone zone) and differing from each other in the chemical compositions and physical properties of the water. A total of 133 species of phytoplankton with prevalence percentages of Bacillariophyta (46%), Chlorophyta (24%), and Ochrophyta (11%) were found; α-diversity varied from 4 to 30 specific and intraspecific taxa per sample. According to Spearman’s correlation coefficients, the diversity indices (Shannon, Pielou, Simpson) were mainly determined by the number of dominant species. The uniquely high (up to 130 g/m3) biomass of phytoplankton was noted in the ecotone, on the border between the water column and the bottom. The formation of mono- and oligo-dominant nannoplankton diatom communities with a predominance of the rare species Cyclotella distinguenda Hustedt was demonstrated there. The roles of flagellate algae and cyanobacteria were found to be less significant.
Evaluation of University Review Program for Teachers’ Licensure Examination: A Transformative Mixed Methods Study Using Bourdieu-Scheerens Framework

Guided by the Bourdieu-Scheerens framework, this study uses transformative mixed methods exploratory sequential design to evaluate the “LET Intensive Review,” a university program for the Licensure Examination for Teachers (LET). The review program is regarded as an input, a means for achieving an output. While analysis includes the context, inputs, process, and outputs in education function, close attention is given to processes to elucidate contributing factors in the LET outcomes. Ethnography as the primary research design was used to explore pre-service teachers' (PSTs) experiences in the review, deploying the Bourdieusian framework in the analysis. In support of the qualitative findings, a descriptive research design was employed. The Mann-Whitney U Test and the Independent Samples t-test were performed to analyze the university passing percentage ratings in the LET elementary and secondary levels for first-timers before and during the conduct of the review. Integrative analysis of the qualitative and quantitative results followed to draw the mixed methods research findings. This evaluation reveals that the LET Intensive Review is effective, and the faculty agency and the administrator agency play a big part in the process. Most of the LET elementary level first-timers who took the review obtained significantly higher LET ratings than those from the previous batches who had not gone through the review. Financial constraints, weak basic education foundation, majorship, and low motivation affected the PSTs’ performance and education quality. The educational policy implications related to the urban-rural divide are also presented in this study.
Differences in the teaching of civic, social and political education: An analysis of the impact of school gender

This study examines differences based on school gender in the teaching of Civic, Social and Political Education (CSPE), a mandatory subject in the Irish post-primary curriculum. These differences are considered in relation to Westheimer and Kahne’s three types of citizens – personally responsible, participatory and justice-oriented. The article presents the findings of a survey conducted with 223 CSPE teachers in single-sex female, single-sex male and co-educational schools. The data were analysed using statistical and thematic analysis. The findings suggest that CSPE teachers in single-sex female schools place greater value on the subject and are more likely to promote social responsibility and student voice, suggesting a greater emphasis on participatory and justice-oriented citizenship. Teachers in single-sex male schools are more likely to focus on politics and action aligning with participatory citizenship. In co-educational schools, teachers seemed to focus on personally responsible and participatory citizenship.
The distribution of the desert meteorites in China and their classification

In recent years, numerous meteorites have been collected in desert areas in northern and western China. We describe the environment of some deserts in this region, and the petrological and mineralogical characteristics of 49 of the recovered ordinary chondrites. They consist of 14 H chondrites, 33 L chondrites, and 2 LL chondrites. Of the 300 desert meteorites with approved names from deserts in China, there have been 287 ordinary chondrites, six iron meteorites, one CO3 chondrite, one diogenite, one ureilite, one brachinite, one eucrite, and one EL7 chondrite. Forty‐two dense meteorite collection areas (DCAs) have been defined, mainly located in northern and western China. The meteorites collected are mainly from the Kumtag DCA, followed by the Alatage Mountain, Loulan Yizhi, Hami, and Lop Nur DCAs. After tentative pairing of the meteorites, we estimate that the ordinary chondrites account for 72% of the desert meteorites collected in China, with 63 H chondrites, 133 L chondrites, and 20 LL chondrites. This dominance of L chondrites contrasts with other deserts, which may result from the insufficient collection or bias in pairing of ordinary chondrites. The mass distribution of meteorites from different DCAs in China is consistent with that from DCAs in Africa. Based on the available information and the meteorite flux model proposed by previous studies, we suggest that the time over which meteorites have been accumulated in the southern Hami DCA might be >10 kyr. Therefore, the southern Hami region is currently the most suitable area for meteorite collection in China.
Current Perspective of Traditional Chinese Medicines and Active Ingredients in the Therapy of Hepatocellular Carcinoma

Abstract Hepatocellular carcinoma (HCC) is one of the leading lethal tumors worldwide, and the treatment remains a great medical challenge. Surgery and chemotherapy are current standard curative methods for patients with HCC, but the prognosis is still dismal. Based on unique medical theories and rich practical experience, traditional Chinese medicine (TCM) has been broadly employed to effectively treat HCC for a long history. Recently, systematic clinical trials have been well designed to study the efficacy of TCMs in the treatment of HCC, and the underlying antitumor mechanisms were also deeply explored. Here, we reviewed the published clinical evaluation of some commonly used TCMs in the treatment of HCC, and the related anti-HCC mechanisms through in vitro and in vivo study, promoting the modernization of TCM study in oncology for achieving a substantial reduction of HCC burden in the future.
Treatment Approaches for First Episode and Early-Phase Schizophrenia in Adolescents and Young Adults: A Delphi Consensus Report from Europe

Purpose Although first-episode psychosis (FEP) in youth, particularly early-onset schizophrenia (EOS), is managed similarly to adult-onset schizophrenia, few antipsychotics are approved for people aged 13–18 years. We aimed to explore areas of uncertainty in EOS management and provide evidence-based recommendations to mental health specialists. We used the Delphi methodology to gain knowledge in areas lacking evidence-based strategies. This standardized methodology consists of the development of a questionnaire by content experts, which is then submitted to a broader panel of professionals (panelists) to survey their level of agreement on the topics proposed. Materials and Methods The developed questionnaire covered patient management from diagnosis to maintenance treatment and was administered to a broader panel of specialists across Europe. Based on an analysis of responses received in this first round, the items that needed further insight were submitted to the panel for a second round and then reanalysed. Results An initial set of 90 items was developed; in round I, consensus was reached for 83/90 items (92%), while it was reached for 7/11 (64%) of the items sent out for rerating in round II. Feedback for rounds I and II was obtained from 54/92 and 48/54 approached experts, respectively. There was broad agreement on diagnostic standards, multimodal approaches and focus on adverse events, but uncertainty in terms of pharmacological strategies (including clozapine) in case of failure and antipsychotic dosing in younger patients. Conclusion Despite knowledge about diagnostic clues and integrated management of EOS, this study highlights the lack of standardization in treating EOS, with safety arguments having a major role in the decision-making process. Targeted clinical trials and systematic dissemination across Europe of current scientific evidence on the value of early intervention services is hoped to contribute to standardized and improved quality care for patients with early-phase psychosis and schizophrenia.
Operating characteristics of the low-lift air lift pump

Using air-lift pump to lift water proves to be good,equipment simple,covering area small and investing less,particularly in sewage treatment engineering,for the head under 3 m situation,while the market of low lift water pump product is little and its efficiency is low.If a higher head pump is used,it will not only waste energy but also shorten the life of the pump as the pump will work outside of high efficient area.The principle of the air lift pump is using the bubble as a pneumatic piston,rising material to promote the pipeline and expand to form a gas-water mixture.The density of the gas-water mixture as a driving force is less than the density of the surrounding water,the buoyancy generated thereby leaving the water to rise.Research shows that air-lift pump water flow has a connection with air flow,submerged depth and hoisting height.What's more,it is proportional to the air flow and the growth of submerged depth;and out-water flow is inversely proportional to the hoisting height.
Socio-Economic Benefits in Community Energy Structures

In this paper, the authors examine how a community energy group in the Meadows area of Nottingham in the UK adopted a model of local energy generation and storage as a means of combatting climate change, improving energy efficiency, enhancing energy security, and reducing fuel poverty. By prioritising local needs and managing expectations, this approach was seen to unite community members in acting on energy challenges while increasing knowledge, understanding, and awareness of energy issues in general. The results of the survey indicated that the respondents had a significantly high level of climate awareness (94%) and support for community energy (90%). Furthermore, evidence of the impacts and efficiencies of community energy and subsequent socio-economic benefits were identified, including 89% of respondents reporting a reduction in energy costs and 67% of respondents increasing their self-consumption. Importantly, the barriers experienced when trying to maximise the identified socio-economic benefits are highlighted and general recommendations given.
Resource optimization in UAV‐assisted wireless networks—A comprehensive survey

Unmanned aerial vehicles (UAVs) are inevitable to meet the requirements of future wireless networks. Recently, researchers have investigated diverse issues related to UAV‐assisted networks (including placement of UAVs, resource management, and spectrum sharing) for a broad range of applications, including disaster management, data collection from the ground sensor network, surveillance, logistic support, etc. This article presents a comprehensive survey of recent advances in UAV‐assisted networks. We mainly emphasize the optimization perspective of UAV‐assisted wireless networks with different objectives, including coverage area, throughput, energy efficiency, quality of service, delay, and outage probability. We provide a detailed discussion for each objective with their constraints, optimization problem, solution approach, and performance metrics. We also provide relationships among different objectives and parameters considered in the literature. Finally, we list open research issues and future research directions to improve UAV‐assisted wireless networks in the context of optimization.
