Photochemically induced structure transfer from analogous azobenzenes and stilbenes onto a liquid crystalline phase

The photoinduced structure transfer from different 4-N,N-diethylamino-4′-alkoxyazobenzenes and analogous stilbenes onto a nematic liquid crystalline phase has been investigated. The structure transfer caused by the azobenzenes was found to be 7–8 times smaller than for the corresponding stilbenes. The photoinduced E→Z isomerization of the azobenzenes occurred in the liquid crystal more slowly than the thermal back reaction. In contrast, despite lower rate constants for the E→Z photoisomerization, the stilbenes under investigation brought about a greater structure transfer because no thermal back reaction was found at 25 °C.Investigations carried out with the azobenzenes in ethanol and cyclohexane showed the great influence of the polarity of the surrounding medium on the ratio between the rate constants for the E→Z photoisomerization and the thermal Z→E back reaction. This ratio kE→Z/kZ→E,therm increased at 25 °C from ca. 0.15–0.5 in the highly polar liquid crystal to ca. 13–19 in ethanol and nearly 500 in the apolar cyclohexane.This paper concludes that only the investigated stilbenes are suitable for photoaddressed displays using highly polar, thermotropic liquid crystals.
Japanese elementary school teachers’ professional experiences of long working hours

This study is an in-depth investigation of the experiences of a small group of elementary school teachers in Japan, who have among the longest working hours in the world. A total of eight teachers from four public elementary schools volunteered to take part in this study. Its design is descriptive-qualitative, using an in-depth, semi-structured interviewing approach which is well-suited to understanding complex academic and social phenomena. Through field visits and interviews, a number of demands were identified that place considerable stress on teachers, all of which relate to extra-curricular expectations beyond the core roles of planning, teaching and assessment. Few resources are available to help cope with these demands, leaving teachers overwhelmed and exhausted, and frustrated as they have little recourse to affect change. The findings should serve as a warning of the risks to teacher well-being.

Today, the idea that the sustainable city of the future should meet human needs and maintain a higher quality of life is worldwide unanimously accepted. The aim of this paper is to present results regarding the production of alkali-activated fly ash-based geopolymer concrete, a new, alternative material, produced using local available raw materials from Romania.
Could integrated subtitles benefit young viewers? Children’s reception of standard and integrated subtitles: a mixed methods approach using eye tracking

ABSTRACT This paper investigates children’s reception of AV content with standard and integrated interlingual subtitles. To this end, an experimental study was conducted with 17 children aged 8–9 years, to assess their reception of clips of an animated film in Spanish with standard and integrated subtitles in English. A mixed methods approach was adopted with the aim of obtaining a robust, comprehensive understanding of the children’s reception of the subtitled AV content, using eye tracking, scene recognition tests, content comprehension tests, questionnaires, and interviews. It was established that the children spent a significantly larger proportion of their viewing time looking at the images and also fixated more times on the images when the subtitles were in the integrated position. However, the hypothesis that participants would exert lower levels of cognitive effort when watching the AV clips with integrated subtitles was only partially confirmed. The integrated subtitles did not have detrimental effects on their viewing patterns, scene recognition performance, or comprehension of the clips. The majority approved highly of both subtitle positions and perceived both as easy to read and understand. These findings show that further research in this area is warranted.
Modelling the effect of nanofiller’s shape and alignment on the dielectric strength and permittivity of polyethylene nanocomposite insulation

Solid insulation defects are a major cause of power failures. Incorporation of micro and nanoparticles in the solid insulation materials has proven its advantage. It has been reported that nanocomposites are far superior in terms of insulation to microcomposites because of larger interphase area between nanofillers and polymer in nanocomposites. In addition to that nature, size, shape, concentration and alignment of nanofillers affect the properties of resulting nanocomposite insulation. A lot of work has reported the effect of nanofiller’s nature, size and concentration but very little is reported on the effect of filler’s shape and alignment on the insulation and dielectric properties. In this paper nanocomposite dielectrics with nanofillers of various shapes and alignment are modelled by varying their permittivity using finite element method. To characterize the effect of various shapes and orientation electric field intensity and energy density models are computed. Simulations are performed using AC/DC module of COMSOL Multiphysics. The results revealed that shape and alignment of nanofillers are the two key factors in tuning the breakdown strength and permittivity of nanocomposite dielectrics for their applications in insulation as well as high voltage capacitors.
Alumina Nanoparticles for the Removal of Ni(II) from Aqueous Solutions

Alumina nanoparticles were developed by the sol−gel method and were used for the removal of Ni(II) ions from aqueous solutions. The nanoparticles were characterized by TEM and XRD. Nanoparticles of alumina were then used for removal of Ni(II) ions from aqueous solutions of nickel. The nanosize of the adsorbent was confirmed by TEM and XRD. Removal (%) was found to be dependent on the initial concentration of nickel, and maximum removal was found to be 96.6% at 25 mg/L Ni(II). The removal increased from 99 to 99.6% by decreasing the initial concentration from 75 to 25 mg/L. Equilibrium time was found to be 120 min. As expected, higher removal was obtained at higher adsorbent dose. The removal was governed by first-order kinetics, and the value of the rate constant of adsorption was found to be 1.83 × 10−2 min−1 at 25 mg/L and 25 °C. The removal was found to be pH dependent, and maximum removal was found to be at pH 8.0. The adsorption process was endothermic in nature. The experimental data fit well the La.
Development and Feasibility Testing of Video Home Based Telerehabilitation for Stroke Survivors in Resource Limited Settings

Tele-physiotherapy has been shown to be valuable to improve clinical outcomes after stroke. Yet, home-based interventions for stroke survivors (SSVs) who speak indigenous African languages are sparse. This study developed a video-based home exercise programme (VHEP) for SSV speakers of Yoruba. A qualitative descriptive pilot study was conducted in two phases: development and feasibility testing. VHEP development followed the American Stroke Association's recommendations to include demonstrations of task-specific mobility-task and postural training; trunk exercises, and overground walking. The exercise instructions were presented in the Yoruba language. Each exercise was demonstrated for five minutes on video for a total of 30 minutes. The feasibility testing involved ten consenting chronic SSVs. Each imitated the VHEP twice per week for two weeks and thereafter completed a feasibility questionnaire. Criteria for feasibility were: cost of using VHEP, recruitment rate, retention of participants, adherence to the exercises, and intervention delivery. The ten SSVs were recruited within one week, had prior home access to a video player at no-cost, adhered to the exercises as recorded, completed the 30 minute-duration for two weeks, and confirmed intervention delivery of VHEP. Most participants liked the novel use of Yoruba as the language of instruction on VHEP. The VHEP was feasible and acceptable among the studied sample of SSVs. Video based home telerehabilitation for SSVs therefore has the potential to meet the growing need for tele-physiotherapy in resource limited settings.
Cannabinoids Accumulation in Hemp (Cannabis sativa L.) Plants under LED Light Spectra and Their Discrete Role as a Stress Marker

Simple Summary Cannabinoids accumulation in the hemp plant greatly depends on light quality under a controlled growing system. Sativa-type hemp plant (enriched with THC) increased CBD accumulation under some controlled light combinations. Green light has a significant role in CBD and CBDA synthesis, where FR and UV-A (along with green) play a positive and negative role in this process, respectively. Earlier, cannabinoids were identified as stress markers, but it was unclear which compound/compounds are directly involved with the light stress environment as stress markers in the hemp plant. In our study, THCA showed a significant role as a stress marker followed by CBDA. On the other hand, THC and CBD showed a negligible response as stress response compounds to such conditions. Abstract Hemp adaptability through physiological and biochemical changes was studied under 10 LED light spectra and natural light in a controlled aeroponic system. Light treatments were imposed on 25 days aged seedlings for 16 h daily (300 µmol m−2 s−1) for 20 days. Plant accumulated highest Cannabidiol (CBD) in R7:B2:G1 light treatment, with relatively higher photosynthetic rate and lower reactive oxygen species, total phenol content, total flavonoid content, DPPH radical scavenging capacity, and antioxidant enzymatic activities. Tetrahydrocannabinol (THC) also accumulated at a higher level in white, R8:B2, and R7:B2:G1 light with less evidence of stress-modulated substances. These results indicated that CBD and THC have no or little relation with light-mediated abiotic stress in hemp plants. On the contrary, Tetrahydrocannabinolic acid (THCA) was accumulated higher in R6:B2:G1:FR1 and R5:B2:W2:FR1 light treatment along with lower photosynthetic rate and higher reactive oxygen species, total phenol content, total flavonoid content, DPPH radical scavenging capacity, and antioxidant enzymatic activities. However, Cannabidiolic acid (CBDA) was accumulated higher in R6:B2:G1:FR1 light treatment with higher stress-modulated substances and lower physiological traits. CBDA was also accumulated higher in R8:B2 and R7:B2:G1 light treatments with less evidence of stress-modulated substances. Besides, Greenlight influenced CBD and CBDA synthesis where FR and UV-A (along with green) play a positive and negative role in this process. Overall, the results indicated that the treatment R7:B2:G1 enhanced the medicinal cannabinoids most, and the role of THCA as a stress marker is more decisive in the hemp plant than in other cannabinoids under attributed light-mediated stress.
Flaxseed Prevents Interferon-alpha Induced Depressive Behavior in Mice: the α-Linolenic Acid is Essential

Background and objectives: Interferon-alpha (IFN-α) is a cytokine with various clinical applications, but it may induce depression by decreasing tryptophan level and producing neuroactive metabolites. Since Linum usitatissimum (flaxseed) is a valuable source for amino acids, α-linolenic acid (ALA), and lignans that could prevent inflammation and neurotoxicity, flaxseed effects on IFN-α induced depressant was evaluated. Methods: Flaxseed was applied either by whole ground flaxseeds in mice diet, or flaxseed oil by gavage feeding tube until effective antidepressant effects were observed. Seventy-eight male albino mice 25±3 g were used and divided in 13 groups, IFN-α 16×10 5 IU/kg was injected for 6 days. After the locomotor test, the forced swimming test (FST) was used to measure the immobility time indicating despair behavior, and the sucrose preference test measured anhedonia. Results: There were only marginal differences in the locomotor activity; however, the immobility time increased by IFN-α (154.5±11.22 s, vs control 121.3±7.14 s; p=0.031), and sucrose preference was 65% indicating depression. The administration of flaxseed 30% or flaxseed oil 25% with IFN-α significantly reduced the immobility time (92.67±11.60 s and 94.17±10.12 s, respectively, vs IFN-α normal diet, p<0.01), sucrose preference also increased that supported the antidepressant effect. Conclusion: Flaxseed could prevent IFN-α induced depressive-like behavior in mice. Although interpretation from animal to human studies needs careful attention, this study supports the use of flaxseed in the diet as reasonable strategy to prevent depression in high-risk individuals, such as patients treated with IFN-α.
A lean UX approach for the engineering user interfaces in the Square Kilometre Array project

Development of engineering user interfaces for a radiotelescope can greatly benefit from a Lean UX approach. In this paper we analyse the situation for the SKA project, a very large endeavour that involves dozens of agile teams, hundreds of developers and many more stakeholders, for a system whose lifespan will be several decades. The paper describes how we are establishing a Lean UX process appropriate for the current stage of the SKA project. We outline the four major challenges that need to be overcome, and that constitute our starting point for defining the overall goals characterizing the desirable process. On this basis, we present the adoption plan. The Lean UX process we envision is suitable for developing software for a very complex social and technical collaboration such as SKA where software is being developed with a quite sophisticated agile framework. Similar decisions are likely to be made on many large scientific projects that are developed with agile methods.

The distracted phone-use behaviours among pedestrians, like Texting , Game Playing and Phone Calls , have caused increasing fatalities and injuries. However, the research of phone-related distracted behaviour by pedestrians has not been systemically studied. It is desired to improve both the driving and pedestrian safety by automatically discovering the phone-related pedestrian distracted behaviours. Herein, a new computer vision-based method is proposed to detect the phone-related pedestrian distracted behaviours from a view of intelligent and autonomous driving. Speciﬁcally, the ﬁrst end-to-end deep learning based Two-Branch Convolutional Neural Network (CNN) is designed for this task. Taking one synchronised image pair by two front on-car GoPro cameras as the inputs, the proposed two-branch CNN will extract features for each camera, fuse the extracted features and perform a robust classiﬁcation. This method can also be easily extended to video-based classiﬁcation by conﬁdence accumulation and voting. A new benchmark dataset of 448 syn-chronised video pairs of 53,760 images collected on a vehicle is proposed for this research. The experimental results show that using two synchronised cameras obtained better performance than using one single camera. Finally, the proposed method achieved an overall best classiﬁcation accuracy of 84.3% on the new benchmark when compared to other methods.
Hydrologic and water quality impacts of agricultural drainage

Abstract While some of the world's most productive agriculture is on artificially drained soils, drainage is increasingly perceived as a major contributor to detrimental off‐site environmental impacts. However, the environmental impacts of artificial or improved agricultural drainage cannot be simply and clearly stated. The mechanisms governing the hydrology and loss of pollutants from artificially drained soils are complex and vary with conditions prior to drainage improvements and other factors: land use, management practices, soils, site conditions, and climate. The purpose of this paper is to present a review of research on the hydrologic and water quality effects of agricultural drainage and to discuss design and management strategies that reduce negative environmental impacts. Although research results are not totally consistent, a great majority of studies indicate that, compared to natural conditions, drainage improvements in combination with a change in land use to agriculture increase peak runof.
Counselling for Chronic Insomnia in Swiss Pharmacies: A Survey Study Based on Case Vignettes

(1) Introduction: Chronic insomnia (CI) reduces quality of life and may trigger depression and cardiovascular diseases. The European Sleep Research Society recommends cognitive behavioural therapy (CBT-I) as the first-line treatment. Because a recent study in Switzerland demonstrated that this recommendation was inconsistently followed by primary care physicians, we hypothesised that pharmacists also deviate from these guidelines. The aim of this study is to describe current treatment practices for CI recommended by pharmacists in Switzerland, compare them to guidelines and examine their attitudes towards CBT-I. (2) Methods: A structured survey was sent to all the members of the Swiss Pharmacists Association, containing three clinical vignettes describing typical CI pharmacy clients. Treatments had to be prioritised. The prevalence of CI, and the pharmacists’ knowledge and interest in CBT-I were assessed. (3) Results: Of 1523 pharmacies, 123 pharmacists (8%) completed the survey. Despite large variations, valerian (96%), relaxation therapy (94%) and other phytotherapies (85%) were most recommended. Although most pharmacists did not know about CBT-I (72%) and only 10% had recommended it, most were very interested (64%) in education. Missing financial compensation hampers the recommendation of CBT-I. (4) Conclusions: Contrary to existing European guidelines, community pharmacists in Switzerland mostly recommended valerian, relaxation therapy and other phytotherapies for treating CI. This might be connected to the client’s expectation of pharmacy services, e.g., medication dispensing. While pharmacists recommend sleep hygiene regularly, most did not know of CBT-I as an overarching concept but were willing to learn. Future studies should test the effects of dedicated training about CI and changes in the financial compensation for counselling for CI in pharmacies.

Indonesian Favorite Destinations: Antecedent and Consequence Destination Experience

Almost all countries in the world try to increase the attractiveness of tourist destinations owned by their countries, including Indonesia. Various strategies have been decided by the stakeholders in the tourism industry to lure tourists to their tourist destinations. The purpose of this study is to develop a model in the tourism industry by analyzing tourist behavior in returning visits to a tourist destination. This study uses a survey method with a quantitative approach. The attitude measurement scale is the differential magnetic scale, the primary data obtained from 502 respondents who had visited Bandung, or Yogyakarta, or Bali. The analytical tool used in this study is Structure Equation Modeling with AMOS 23.0 software. There are six variables examined in this study, namely revisit intention, e-WOM, destination experience, destination identity, destination service quality, and destination natural quality. The results found that revisit intention and e-WOM will be affected by destination experience. A pleasant experience during a visit to a tourist destination can be maintained by the right destination identity and destination service quality. Also, destination experience strengthened by excellent destination natural quality. This research model can be adopted in various tourist destinations to increase the number of tourists visiting.
Design Mode Innovation of Local Color Cultures: A Case Study of the Traditional Female Costume of Yi Nationality

Color is a concrete expression of combining local features and traditional culture. The purpose of this study is to provide a new design method and intends, by taking the traditional costume of the Yi women in Liangshan, China, as an example, to establish a systematic color scheme which can be used as a reference for the establishment of relevant color records for other cultural groups. First of all, through literature review, this study provides the definition of the traditional costume of the Yi women in Liangshan, color and culture and color images and clarifies the characteristics of research samples. Secondly, experts are invited to find out and record the color values of different colors on Yi women’s costume, and a software is resorted to in order to calculate the area ration of each color and analyze the color distribution principles of sample costume. Moreover, this study discusses the color images of Yi women’s costume, sorts out its unique color characteristics and establishes and verifies samples of color scheme through focus group interviews in order to analyze regional cultural colors. Finally, this study proposes a systematic approach for regional cultural color analysis, namely, understanding color characteristics, analyzing color images, establishing a color scheme and demonstrating color scheme principles. Through a systematic approach, these cultural colors are analyzed and organized to establish a regional cultural color scheme, which can not only retain the characteristics of the traditional cultural colors of Chinese ethnic groups’ costume but also serve as a reference for designers to develop regional cultural products.
