Synechocystis Specifically Inhibits Growth of Ralstonia eutropha in an Artificial Microbial Consortium

Petroleum derived plastics are a major contributor to global pollution. There is an urgent need for biodegradable, sustainable plastic alternatives. Cyanobacteria have been studied extensively for photosynthetic production of biofuel precursors including alkanes and free fatty acids. However, large scale production has been slow to emerge from these technologies. Here, we wished to evaluate alternative uses for engineered strains of the cyanobacteria Synechocystis PCC 6803 (6803). We investigated the feasibility of using wild type and fatty acid secreting strains of 6803 to support the growth of Ralstonia eutropha. This organism is capable of producing polyhydroxyalkanoates (PHAs), which can be used in bioplastic production. Traditional feedstocks for R. eutropha include palm oil and other biological precursors that compete with cultivatable land, pitting potential bioplastic production against agricultural demands. Since PHAs are of great interest as plastic alternatives, we co-cultured R. eutropha and 6803 strains in the minimal medium BG-11 in an attempt to create carbon neutral PHA from R. eutropha. Surprisingly, we observed inhibition of R. eutropha growth in co-culture with Synechocystis but not another cyanobacterium suggesting further modification of Synechocystis is necessary for use as a feedstock.
ArUcOmni: detection of highly reliable fiducial markers in panoramic images

In this paper, we propose an adaptation of marker detection algorithm for panoramic cameras such as catadioptric and fisheye sensors. Due to distortions and non-uniform resolution of such sensors, the methods that are commonly used in perspective images cannot be applied directly. This work is in contrast with the existing marker detection framework: Automatic reliable fiducial markers Under occlusion (ArUco) for a conventional camera. To keep the same performance for panoramic cameras, our method is based on a spherical representation of the image that allows the marker to be detected and to estimate its 3D pose. We evaluate our approach on a new shared dataset that consists of a 3D rig of markers taken with two different sensors: a catadioptric camera and a fisheye camera. The evaluation has been performed against ArUco algorithm without rectification and with one of the rectified approaches based on the fisheye model.
Yield, nutritive value and ensilage characteristics of whole-crop maize, and of the separated cob and stover components – nitrogen, harvest date and cultivar effects

SUMMARY The objectives of the present study were to determine the effects of nitrogen (N) application rate, harvest date and maize cultivar on the yield, quality and the subsequent conservation characteristics of whole-crop, cob and stover silages. The experiment was organized in a spilt-plot design, with harvest date (15 September, 6 October and 27 October) as the main plot, and a three (maize cultivars: Tassilo, Andante and KXA 7211)×two (N application rate: 33 and 168 kg N/ha) factorial arrangement of treatments as the sub-plot, within three replicate blocks, and was conducted at Grange, Dunsany, Co. Meath, Ireland in 2009. The three harvest dates represented early, normal and late harvests, respectively, for a midland site in Ireland. Of the three maize cultivars selected, cvars Tassilo and Andante represent conventional cultivars sown by commercial livestock farmers in Ireland, while cvar KXA 7211 is categorized as a high biomass cultivar. No effect of N application rate was observed on the dry matter (DM) yield, nutritive value or ensiling characteristics of maize whole-crop or cob. Whole-crop and stover harvested on the later date had a lower digestible DM (DDM) content and the silages underwent a more restricted fermentation, compared to silages produced from herbage harvested on earlier dates. Cob silages produced from crops harvested on 15 September had lower DDM content and higher DM loss during ensiling than later harvest dates. Despite higher whole-crop DM yields, the later maturing cultivar KXA 7211 did not improve the DM yields of cob and also resulted in increased DM losses from the ensilage of cob, when compared with the other cultivars. In addition to the DM yield and nutritive value of forage maize at harvest, the subsequent fermentation profile during ensilage influences the optimum choice of cultivar and date for crop harvest in a maize silage production system.
Solid State Transformers: Concepts, Classification, and Control

Increase in global energy demand and constraints from fossil fuels have encouraged a growing share of renewable energy resources in the utility grid. Accordingly, an increased penetration of direct current (DC) power sources and loads (e.g., solar photovoltaics and electric vehicles) as well as the necessity for active power flow control has been witnessed in the power distribution networks. Passive transformers are susceptible to DC offset and possess no controllability when employed in smart grids. Solid state transformers (SSTs) are identified as a potential solution to modernize and harmonize alternating current (AC) and DC electrical networks and as suitable solutions in applications such as traction, electric ships, and aerospace industry. This paper provides a complete overview on SST: concepts, topologies, classification, power converters, material selection, and key aspects for design criteria and control schemes proposed in the literature. It also proposes a simple terminology to identify and homogenize the large number of definitions and structures currently reported in the literature.
Início de florescimento, produção e valor nutritivo de gramíneas forrageiras tropicais sob condição de sombreamento natural

An experiment was undertaken to study six different species of tropical forage grasses as their nutritive value, flowering and dry matter production when under the shade of Anadenanthera macrocarpa trees. The grasses Brachiaria brizantha cv. Marandu, Panicum maximum cvs. Aruana, Makueni, Mombaca and Tanzânia, and Cynodon dactylon cv. Tifton 68 were studied. Grass performance under trees was compared to that in a nearby area in full sunlight (check). Shade delayed the initial flowering of all grasses, to a variable degree depending on the species. Grass dry matter yield was reduced by shade, except in harvest 3, where grass growth did not differ between treatments. Tifton 68 was not tolerant to shade and the other grasses exhibited moderate tolerance. The N concentrations in the leaves of all grasses increased significantly under shade in comparison to the full sunlight condition. Similarly, the IVDMD of the whole plants increased under shade condition.
Hydroxyl radical generation and oxidative stress in Carassius auratus exposed to glyphosate and its formulation

Oxidative stress parameters and some antioxidant defense systems in the liver of Carassius auratus exposed to glyphosate and its formulation (Roundup®) have been studied. Fish were exposed to glyphosate and its formulation at concentrations of 0.032, 0.16, 0.8, and 4.0 mg L−1, all calculated on glyphosate basis, for 11 days. Hydroxyl radical generation as determined by electron spin resonance spectroscopy of its spin-adduct with α-phenyl-t-butyl nitrone increased with the concentration of Roundup®. Superoxide dismutase activities were decreased relative to control by 21%–46% when exposed to glyphosate and 45%–52% when exposed to Roundup®, suggesting that the formulation is more toxic than glyphosate alone. Catalase showed no difference between both groups.
The Effect of Leisure Literacy on Leisure Exercise in University Students

Within the scope of the research, which aims to determine the leisure literacy and leisure exercise levels of the university students who volunteer in sports organizations, it is aimed to analyze the relationship and the differences of certain variables with measurement tools, as well as to examine the relationship and impact between leisure literacy and leisure exercise. In this context, 207 sports organization volunteers who participated in the study participated in the data collection, as well as a demographic information form, as well as the “Leisure Literacy Scale” and “Leisure-Time Exercise Scale" was used. In this study, the internal reliability coefficient for the Leisure literacy scale was . 94 and . 70 for the leisure exersice questionnaire. Descriptive statistics, independent sample t test, one-way analysis of variance (ANOVA) test and Tukey (HSD-LSD) test and Pearson Correlation test and regression analysis were used for data analysis. The findings reveal that participants have high leisure literacy (81.25 ± 14.04) and men exhibit more active leisure exercise levels, certain variables change leisure literacy and leisure exercise levels. On the other hand, positive strong relationships between leisure literacy and leisure exercise were determined, and leisure literacy was found to have a positive effect on leisure exercise level. As a result of the research, it can be stated that the volunteer participants who take part in sports organizations and evaluate their leisure time actively, the literacy knowledge, background and action level for their leisure time is an important factor that makes individuals spend their leisure by exercising.
Records of past land use are best stored in soil properties

Four models from selected trait groups (plant functional traits, plant chorotypes, Ellenberg bioindicator values and soil properties) were developed, and their predictive power for the time since land use was abandoned in Southeastern (SE) Slovenia was compared. The analysis highlights an approach that determines the age of forest using ecological, chorological and pedological attributes. The aim of the study was to develop a tool, a combination of functional response traits, chorotypes, ecological characteristics and soil properties, which allows calculation of the time since land use abandonment (TLA) for a particular secondary succession stage. Using old cadastral maps and orthophotos and employing an overlapping technique, the actual TLA for the sample plots was determined, which served as a dependent variable in modelling, as well as a control for modelling accuracy. The predictive power of four different ecological models was compared. The study shows that information about the process of abandonment of traditional land use is stored within the changes of plant functional response traits, chorotypes and Ellenberg bioindicator values of the study area, but is best reflected in soil properties. Soil properties provide the most reliable basis for the elaboration of a prediction model for TLA.
A novel quantitative trait locus, qCL1, involved in semi-dwarfism derived from Japanese rice cultivar Nipponbare

To identify quantitative trait loci (QTLs) associated with culm length in Japanese japonica rice varieties, we conducted QTL analyses using a set of reciprocal backcrossed inbred lines (BILs) from crosses between Nipponbare and Koshihikari. We detected five QTLs in the two BILs that are involved in the culm-length difference between Nipponbare and Koshihikari. A QTL located on the short arm of chromosome 1, qCL1, was commonly detected near the simple sequence repeat (SSR) marker RM8068 in both BILs in three growing seasons. The Nipponbare allele of qCL1 shortened from 1.9 to 3.0 cm of culm length. Substitution lines (SLs) of Koshihikari in which the QTL was replaced with the Nipponbare allele exhibited decreased lengths of lower internodes. qCL1 was mapped within about 2.6 Mbp in the region distal from SSR marker RM10132, suggesting qCL1 differed from the dwarf or semi-dwarf genes that have been previously reported. Japanese japonica rice landraces with Nipponbare alleles of DNA markers around qCL1 had significantly shorter culm length than other landraces. The results suggest that the novel allele for short culm length was originally distributed in Japanese rice landraces and has been used for introducing the semi-dwarf phenotype and improving plant architecture during practical breeding.
Cloning and characterisation of a new rye-specific repeated sequence

In this paper we describe a repetitive DNA sequence unique to the rye genome. The corresponding DNA probe (pAW173) was cloned as a 450-bp fragment and does not hybridize to wheat or barley DNA and is not related to five other repeated DNA families characterised in rye. This new family (designated the R173 family) consists of moderately repeated DNA (~ 15 000 units per genome) and is present on all seven rye chromosomes. The hybridization patterns in Southern blots indicate that it is not organised as blocks of tandem arrays and in situ hybridization shows that it is dispersed throughout the rye chromosomes. The probe has been successfully used as a molecular marker in identifying rye genetic material in a wheat background.Key words: repetitive DNA sequence, rye-specific DNA, molecular marker.
“Tell Tell” - Effects of Personality of Kansei Agents

: The purpose of this study is to propose an emotion generation model that consists of pseudo-personality and pseudo-moods. Agents implementing this model have various personalities for each user. In order to verify its usefulness, we implemented the model on an agent called “Tell Tell” and performed an experimental performance evaluation using a web application. In addition, we tried to performed an experiment to identify the nurtured agents. From the experimental results of performance evaluations, it was found that the agent of the proposed method had a positive difference in impression between " enthusiasm – lose interest " and " human-like – mechanical ". However, in the items of getting tired and fun, there was a significant decrease in subjects with many interactions. From the experimental results of the nurtured agents, it showed that the proposed agent had a higher discrimination rate than the agent with personality only. Therefore, we analyzed the interaction of each subject, the agent of the user who was able to discriminate had little change in personality, and the user who couldn't discriminate had changed personality many times. In the future, it is necessary to improve the impression of getting tired and increase the discrimination rate by implementing an algorithm that changes the facial expression depending on the intensity even for the same personality.
Robotic Arm Assistance System Based on Simple Stereo Matching and Q-Learning Optimization

This study presents a stereo vision robotic arm assistance system, in which five degrees of catching can be performed by the robot arm in a single instance. The algorithm of the control system is built for population-based optimization and specifically aimed to assist people with disabilities. The proposed stereo vision-based robot arm system enables users to manipulate objects based on the robot’s ability to aim at objects by using computer vision. The stereo vision system counts the parameters by focusing on the real-world position of the instance in the coordinate system. A trained deep fully connected network is then adopted to compensate the location measurement errors incurred by the inaccurate parameters measured from the deep learning procedure. Subsequently, the proposed Q-learning-based swarm optimization algorithm is adopted to solve the forward kinematics problem and count the angles of each servo. The performance of the robot arm is compared with several real-life experiments to test its ability to grip a target object in different positions.
Facile Fabrication of Breathable and Superhydrophobic Fabric Based on Silica Nanoparticles and Amino‐Modified Polydimethylsiloxane

This work attempted to fabricate superhydrophobic fabric via simple immersion technique. Textile fabrics were coated with silica nanoparticles prepared from tetraethoxysilane (TEOS) to obtain sufficient roughness with hydrophobic surface chemistry. Then the coated fabrics were treated with polydimethylsiloxane (PDMS) and aminopropyltriethoxysilane (APTES) to reduce the surface energy. The effects of PDMS concentration on the surface morphology and superhydrophobicity of as-prepared fabric were investigated. The morphology and the composition of superhydrophobic fabric was characterized by scanning electron microscopy (SEM), energy dispersive X-ray (EDS) and Fourier transform infrared (FTIR) spectroscopy. The results revealed the formation of spherical silica nanoparticles with average particle size of 250 nm throughout the fabric surface. The possible interactions between silica nanoparticles and APTES, as well as the fabrics were elucidated. Investigating the hydrophobicity of fabrics via water contact angle (WCA) measurement showed that the treated fabric exhibits excellent water repellency with a water contact angle as high as 151° and a very low water sliding angle. It also found that the treated fabric maintained most of its hydrophobicity against repeated washing. The comfort properties of the obtained superhydrophobic fabrics in term of air permeability and bending length did not reveal any significant changes.
Impact of the COVID-19 pandemic on interventional cardiology activity in Spain

Introduction and objectives: The COVID-19 epidemic and the declaration of the state of alarm have led to a decrease in healthcare activity in interventional cardiology units. The objective of this study is to quantify these changes in activity, with special interest in the treatment of patients with ST-segment elevation myocardial infarction (STEMI). Methods: A telematic survey of 81 centers involved in STEMI networks in the 17 autonomous communities of Spain. Information was collected on diagnostic activity, percutaneous coronary intervention (PCI), structural interventions, and PCI in STEMI on changes in the organization of STEMI networks, and on the prevalence of COVID-19 among interventional cardiologists. Data was compared for the week of February 24 through March 1 (before the outbreak) and for the week of March 16 through March 22 (during the outbreak). Results: Response has been obtained from 73 centers (90%). A very significant decrease in the number of diagnostic procedures (–56%), PCI (–48%), structural interventions (–81%) and PCI in STEMI (–40%) has been observed. A slight increase in the use of pharmacological thrombolysis has been reported, although primary angioplasty remains the leading reperfusion strategy. Up to 5% of interventional cardiologists (17) had COVID-19. Conclusions: An important reduction in the activity in interventional cardiology has been observed during the COVID-19 epidemic. Likewise, a great decrease has been detected in the number of patients treated in the STEMI networks, with the risk of increased morbidity and mortality that this represents. Scientific societies and health authorities have to promote that patients presenting STEMI compatible symptoms proceed with no delay to access the health system to receive reperfusion treatment in an appropriate way.
The influence of the nerve on regeneration and maintenance of the barbel of the catfish, ameiurus nebulosus

Regeneration of the extremity of the urodele amphibian ordinarily occurs quite readily, but will not ensue if the stump is deprived of nerves (review, Singer, '52). Moreover, the limb stump is resorbed completely in the case of larval salamanders, provided the denervated condition is maintained (Butler and SchottB, '41; Schott6 and Butler, '41a, '41b). The barbels of the catfish also can regencrate after amputation and, as in the salamander, regeneration depends upon the nerve supply. Thus Olmstead ('20) noted, casual to olnservations on the nerve influence on maintenance of taste buds, that injured barbels do not complete themselves when denervated. The dependence of regeneration of the barbel upon the nerve was confirmed by Olivo ('28) who also reported atrophy of non-amputated barbels following prolonged denervation and by Kamrin ('53) in a note preliminary to the present paper which observed that prolonged nervelessness of amputatcd and unzmputated barbels results in progressive resorption. The present report is devoted to the latter experimental results arid includes histological investigations of the resorptive and regenerative processes.

Temporal pattern of feeding activity in the firebug Pyrrhocoris apterus and its relation to sex, wing dimorphism and physiological state of adults

Abstract The present study tested whether the pattern of feeding activity in the firebug Pyrrhocoris apterus (L.) is sex‐ and wing morph‐related, diurnal or nocturnal, as well as whether the feeding rhythm persists in constant darkness. Temporal patterns of feeding activity are analysed in macropterous and brachypterous adults reared under long‐day (LD 18 : 6 h) and short‐day (LD 12 : 12 h) photoperiods, and in adults transferred to constant darkness. In females, the total feeding activity is highest in long‐day reproductively active brachypters, intermediate in short‐day diapausing brachypters, and lowest in macropters; the differences among males are substantially smaller. Although the total feeding activity of macropterous males is higher than in macropterous females, no sex‐related differences are found in feeding activity of diapausing and reproductively active brachypters. The frequency of feeding exhibits sex‐related differences, with obviously higher values in males. Mean feeding periods of macropterous and reproductively active brachypterous males are shorter than in females of the same wing morph. Mean interfeeding periods are longest in macropters, intermediate in diapausing brachypters, and shortest in reproductively active brachypters, and always lower in males than in females. The study shows that the feeding activity of P. apterus adults is age‐, sex‐ and wing morph‐related, and exhibits a diurnal pattern, except in reproductively active brachypterous females. The latter do not express a clear diurnal rhythm of feeding, presumably because of interactions with cycles of egg development and oviposition. The persistence of diurnal rhythm of feeding activity in short‐day brachypterous females transferred to constant darkness indicates an endogeneity of this rhythm in P. apterus.
Traffic Engineering in Partially Deployed Segment Routing Over IPv6 Network With Deep Reinforcement Learning

Segment Routing (SR) is a source routing paradigm which is widely used in Traffic Engineering (TE). By using SR, a node steers a packet through an ordered list of instructions called segments. By some extensions of interior gateway protocol, SR can be applied to IP/MPLS or IPv6 network without signal protocol. SR over IPv6 (SRv6) is attracting wide attention because of its interoperation ability with IPv6. However, upgrading the existing IPv6 network directly to a full SRv6 one can be difficult, because large-scale equipment replacement or software upgrade may cause economic and technical problems. TE in partially deployed SR network is becoming a hot research topic. In this paper, we propose the TE algorithm Weight Adjustment-SRTE (WA-SRTE) in partially deployed SRv6 network, in which SRv6 capable nodes are dispersedly deployed. Our objective is to minimize the network’s maximum link utilization. WA-SRTE converts the TE problem into a Deep Reinforcement Learning problem and optimizes the OSPF weight, SRv6 node deployment and traffic paths simultaneously. Besides, traffic variation is also considered and we use a representative Traffic Matrix (TM) to epitomize the traffic characteristics over a period of time. Experiments demonstrate that with 20% to 40% of the SRv6 nodes deployed, we can achieve TE performance as good as in a full SR network for the experiment topologies. The results with WA remarkably outperform the results without it. Our algorithm also gets near-optimal results with changing traffic.
