Abstract:

The objective of this work was to evaluate the production of cherry tomatoes in protected environments composed of different photoselective screens. The work was conducted in June / July 2018. The treatments consist of different types of protected environments: open sky, black screen (mesh for 30% shade); white fabric (mesh for 20% shade); blue screen (mesh for 20% of shade) and red screen (mesh for 20% of shade). The experimental design was a randomized block with four replicates, ten plants per experimental plot. The following analyses were performed on cherry tomatoes: leaf number, stem diameter, shoot height, root length, total fresh matter, shoot fresh matter, fresh root matter, shoot dry matter, root, chlorophyll a and chlorophyll b. The black shading, white photoselective, blue photoselective and red photoselective screens did not influence the number of leaves, stem diameter, shoot height, root length, total fresh matter, fresh shoot matter, aerial shoot dry matter, root dry matter, chlorophyll a and chlorophyll b. The red photoselective screen showed superiority in the fresh matter of the root of the other treatments.

Abstract:

Stomoxys calcitrans is considered as a major pest of livestock worldwide. Insecticides have been extensively used to control this pest but resistance to these chemical compounds is now reported in many countries. Therefore, a more sustainable and efficient control is needed. Seven different types of blue screens, with reflectances around 460 nm, were tested during summer 2016 in southwestern France to evaluate their attractiveness and their specificity for stable flies. Height of the screen and orientation (east or west) of a blue screen were also considered. High levels of S. calcitrans captures were recorded during this study (from 141 to 7301 individuals per blue screen and per day) whereas the numbers of tabanids and pollinator insects remained extremely low (less than 10 individuals per screen and per day). No significant difference in attractiveness has been shown between the different types of blue screens. The lower half of the blue screens caught significantly more stable flies (70%) than the higher half (30%). The “east” side of the screen attracted 60% of stable flies but this was not significantly different from the west side. These results are highlighting the interest in these blue polyethylene screens for controlling stable flies in cattle farms, in comparison with more expensive blue fabrics.

Abstract:

Abstract. The fluorescent dye Brilliant Sulfaflavine (BSF, CAS 2391-30-2) was investigated to determine its photo-stability and recovery on five spray deposition collectors: white plastic plate, nylon screen, and stainless steel (SS) screens of three mesh sizes (40, 60, and 80). The photo-stability of the deposited dye was determined by measuring the variance in fluorescence intensity after daylight exposure. The recovery rates were investigated with statically dispensed droplets and dynamically discharged droplets. In addition, droplet penetration through the screen collectors and the amount of unrecovered dye on reprocessed collectors were assessed to better understand the differences in dye recovery rates among different collector types. Photo-degradation tests verified that all collector types were insignificant in fluorescence degradation (<3.1%) after 120 min of solar exposure. Nylon screens had the lowest dye recovery rate (87.0%) for statically dispensed droplets, whereas plastic plates and SS screens recovered more than 90% of deposited dye. For dynamically discharged droplets, the 60-mesh and 80-mesh SS screens recovered more than 70% of the deposited dye, whereas nylon screens showed less than 50% recovery rate. These results were substantiated visually with a high-speed imaging system that detected droplets penetrating more frequently through screens with larger mesh openings. Throughout ten continuous reprocessing cycles of the fluorimetry test, the fluorescence intensity on reprocessed nylon and 80-mesh SS screen collectors increased by 16.8% and 12.7%, respectively, while there was less than 1% change in fluorescence intensity on the 40-mesh and 60-mesh SS screens. These results were clarified through dye residue verification using digital image analysis. Keywords: Fluorescence intensity, Photo-degradation, Recovery rate, Spray deposition assessment, Stainless steel screen.

Abstract:

Time on screens (screen time) on multiple digital devices (computers, mobile phones, tablets, television screens, etc.) due to varied motivations (work, leisure, entertainment, gaming, etc.) has become an integral part of population behaviour. However, a significant evidence gap exists in screen time accumulated over ubiquitous mobile devices such as smartphones. This study aimed to develop an accurate, reliable and replicable methodology to derive objective screen time (i.e., screen-state) from all types of citizen-owned smartphones. A convenience sample of 538 adults (≥18 years) from two largest urban centres in Saskatchewan, Canada (Regina and Saskatoon) was recruited in 2017 and 2018. Participants used a custom-built smartphone application to provide objective and subjective data. A novel methodology was developed to derive objective screen-state, and these data were compared with subjective measures. The findings showed that objective screen-state from smartphones can be derived and assessed across a range of cut-points that take into consideration varied measurement errors. When objective measures were compared with subjective reporting, the results indicated that participants consistently underreported screen time. This study not only provides a methodology to derive objective screen-state from ubiquitous mobile devices such as smartphones but also emphasises the need to capture context via subjective measures.

Abstract:

Illusory self-motion (vection) can be generated by visual stimulation. The purpose of the present study was to compare behavioral vection measures including intensity ratings, duration, and onset time across different visual display types. Participants were exposed to a pattern of alternating black-and-white horizontal or vertical bars that moved either in vertical or horizontal direction, respectively. Stimuli were presented on four types of displays in randomized order: (a) large field of view dome projection, (b) combination of three computer screens, (c) single computer screen, (d) large field of view flat projection screen. A Computer Rod and Frame Test was used to measure field dependence, a cognitive style indicating the person’s tendency to rely on external cues (i.e., field dependent) or internal cues (i.e., field independent) with respect to the perception of one’s body position in space. Results revealed that all four displays successfully generated at least moderately strong vection. However, shortest vection onset, longest vection duration, and strongest vection intensity showed for the dome projection and the combination of three screens. This effect was further pronounced in field independent participants, indicating that field dependence can alter vection.

Abstract:

Applied electrostatic engineering can be used to construct greenhouses that prevent entry of insect pests. Two types of electric field screen were used to exclude pests from the greenhouse: single- and double-charged dipolar electric field screens (S- and D-screen, respectively). The S-screen consisted of iron insulated conductor wires (ICWs) arrayed in parallel (ICW-layer), a grounded metal net on either side of the ICW-layer, and a direct current voltage generator. S-screens were attached to the side windows of the greenhouse to repel whiteflies (Bemisia tabaci) that approached the nets. The D-screen was installed in a small anteroom at the greenhouse entrance to capture whiteflies entering through it. The ICW-layers of the D-screen were oppositely charged with equal voltages and arrayed alternately, and an insulator board or grounded metal net was placed on one side of the ICW-layer. The ICW-layers captured whiteflies entering the electric field of the double-charged dipolar electric field. Three screens equipped with yellow or gray boards or a grounded metal net were installed in the anteroom based on the airflow inside the room, as most whiteflies were brought in by air when the door was opened. Two D-screens with boards were useful for directing the airflow toward the wall with the netted D-screen. This screen eliminated the insects and the pest-free air was circulated inside the greenhouse. The D-screen with the yellow board attracted the whiteflies and was effective for trapping them when there was no wind. Our method kept the greenhouse pest-free throughout the entire period of tomato (Solanum lycopersicum) cultivation.

Abstract:

In this article I set out an argument that skins and screens, once distinctly different types of surface, are merging. I show how in contemporary highly mediatized worlds skins are required to be visually expressive while also noting a parallel movement whereby screens are becoming more affective. Using the ‘designer vagina’ – specifically labiaplasty – as a case study I show how ideal bodies exist simultaneously as screen and as skin, as image and as affect. In turn, I argue that two-dimensional images and three-dimensional ‘real life’ bodies are blending in ways that parallel skin–screen mergers.

Abstract:

This study aimed to evaluate the characterization and bioaccumulation of metals of the golden mussel encrusted in the screens of net cages installed in the reservoir of Itaipu Binacional. The experimental design was completely randomized, composed of two types of screens (PVC and Bezinal) distributed on four sides (Sides I, II, III, and IV) of the net cage. The total mass, the average mass, and the dimensions (width, height, and length) of the mollusks were evaluated. The mussels adhered to the Bezinal screen presented a higher average mass, length, height, and width than those colonized on the PVC screen (p <0.05). However, the PVC screen provided a greater (p <0.05) total mass of encrusted mussels. Regardless of the screen used, the average mass and length of mussels had higher values on Side I (p <0.05) than to the Sides II and IV, but not different from Side III. The mussels evaluated showed high levels of metals, and those encrusted in the Bezinal screen presented higher levels of Al, Zn and Cr than the individuals on the PVC screen (p <0.05). The use of a Bezinal screen is more efficient than a PVC screen, as an antifouling material. Mussels with shorter lengths had a higher incidence on the PVC screen. The mussels encrusted in the Bezinal screen bioaccumulate higher content of Al, Zn, and Cr. The type of screen used in the net cages influences the mass and size of adhered mussels, as well as can interfere with the metal accumulation in the golden mussel.

Abstract:

The Moscow underground (Metro) today is showing active development: new series of trains appear; stations are being built. Apart from material-plastic medium, the screen, virtual reality also emerges. It plays the key role in establishing a new metro mythology. This paper attempts to trace new perspectives of the underground’s virtual life and the points of their interfacing with the objective, material environment. One can loosely specify three types of screen media in the Moscow Metro: information panels (located above the doors in cars), interactive structures (Info-SOS at stations and screens with sockets in “head” and “tail” parts of modern trains), “television” screens” (In the lobby and built-in between car`s door and window, where the Moscow metro lines were traditionally located, and small screens at the eye level of standing passengers). They have different semantic content and types of communication with passengers. There are a number of evident trends in providing video sequence on screens of the Moscow metro in the second half of 2019. The headings broadcast on the screens went sequentially, from more socially significant subjects to quizzes and announcements. The alternation of short stories gave the impression that it took less time to travel. The entire block of on-screen information worked on the effect of “accelerating” time, creating the illusion of greater rapidity of the subway. The Moscow metro today is not so much about the architectural environment but rather a virtual communicative one, which, in addition to entertaining, calming, distracting from problems and uplifting, also represents a function of animating the metro, informing it with a temperament and intonation component. In the process of immersion in a simulated media of the Moscow metro, one finds out that it turns to be a virtual organism with a complex system of “organs”, its own nervous system and its own needs. The first and foremost of which is to preserve, strengthen the love of their passengers, perhaps even make them addicted to the metro environment and inspire them for continuous improvement and modernization of the world.

Abstract:

The objective of this study was to examine peanut (Arachis hypogaea L.) kernel percent sound splits as a function of sound mature kernel seed size when shelled on a reciprocating sheller. Data were compiled from a total of 139 field experiments conducted in the Virginia-Carolina region and Georgia from 2005 to 2020. Runner and Virginia peanut market types were graded according to United States Department of Agriculture (USDA) standards using standard sheller screens with upper grid sizes corresponding to the red pan from the pre-sizer of 10.3 × 19.1 mm (26/64 × 3/4 ″) and 13.5 × 25.4 mm (34/64 × 1 ″) with minimum bar grid clearances of 8.7 (11/32 ″) and 12.7 mm (1/2 ″), respectively. A subset of runner market type samples was graded using the Virginia sheller screen. Grade data per market type and sheller screen was analyzed separately. Among runner market types shelled with the standard runner-type screen, percent sound splits increased linearly with increasing seed size at the logit rate of 1.16 per sound mature kernel g (p < 0.001). Sound splits for Virginia and runner market types shelled on the standard Virginia-type screen did not significantly vary by kernel size (p = 0.939 and 0.687, respectively). Extra-large kernels (proportion) for Virginia types linearly increased with seed size at 1.91 per sound mature kernel g (logit scale) (p < 0.001). Runner market types sized 75 to 91 g/100 sound mature kernels (605 to 500 seed/lb) were estimated to have a 50% probability of a 2.3 to 4.5% or greater increase in sound splits when shelled with the standard runner-type screen compared to runner-type seed sized 55 g/100 sound mature kernels (820 seed/lb), respectively, equivalent to a potential deduction increase of 1.8 to 4.4 USD /1000 kg. For both Virginia and runner market types, seed weight linearly increased with pod weight at 0.169 and 0.195 g/g (p < 0.001), respectively. Results from this study may be used as a reference to suggest runner-type seed sizes above which larger reciprocating sheller screen utilization in line with USDA grading practices is warranted to reduce mechanically induced sound splits during grading and subsequent economic deduction penalties for corresponding farmer stock peanut.

Abstract:

Introduction: The time that adolescents spend in front of some screen as TV, computer, video games and mobile phones, has been considered a risk factor for obesity and non-communicable chronic diseases.Objective: To analyze the effectiveness of two types of low impact training on the screen time and the BMI of overweight adolescents.Methods: Sixty-seven adolescents were allocated into three groups: control group (CG); hydrogimnastic (HG); and jump (JG). The three groups had a weekly session of nutritional guidance; Additionally, the HG and JG trained 12 weeks with three weekly sessions ranging between 24 and 32 minutes as stage periodization training with hydrogimnastic and jump, respectively. Anthropometric measurements were performed, and screen time through a questionnaire created for this study in order to identify the amount of hours that adolescents passed in front of a screen. The questionnaire was carried out before and after the training period, as well as anthropometric assessments.Results: There was no difference pre and post-intervention in screen time for the three groups, however, there was a decrease in BMI in both exercise groups of the pre-training period for post-training.Conclusion: There was no reduction of the screen time, however the BMI decreased in the exercise groups.

Abstract:

With not much to do in their neighborhood, youth may spend more time in the home engaged in screen-based activities. Screen time data from 2,790 youth in the Western Australian Health and Wellbeing Survey were linked to objectively measured count of types of neighborhood “services,” “convenience goods,” “public open space,” and “youth-related” destinations. On average, youth accrued 801 mean min/week screen time and had access to seven different types of neighborhood destinations. A larger number of different types of neighborhood “youth-related,” “service,” and “total” destinations were associated with less screen time (all p ≤ .05). A significant gender interaction was observed. Girls with access to ≥12 youth-related destinations had 109 fewer mean min/week screen time, compared with girls with 0 to 3 youth-related destinations. Providing alternatives to screen use by ensuring access to a variety of neighborhood places for structured and unstructured activities may be an important strategy for decreasing youth screen time.

Abstract:

Screen cast as a viable digital tool to enhance vocabulary learning and retention is quite rare in many language contexts in Iran. It was stipulated that the application of different gloss types as a new pedagogical technique could be of value for this purpose. Therefore, the present study aimed at investigating the effect of different gloss types presented through screen cast on learning vocabulary and working memory (WM). For this purpose, 60 male Iranian EFL learners were assigned to three equal groups (i.e., two experimental and a control group). After pre-tests, the experimental groups were taught vocabulary through different gloss types (i.e., lexical and topic-level) by means of a screen cast presentation. The control group was instructed through traditional techniques. The analysis of the data in post-tests revealed that the experimental groups outperformed the control group. It is thus suggested that gloss types presented via screen cast can boost EFL learnersâ€™ vocabulary knowledge and WM. This result can have pedagogical implications for EFL teachers and material developers. Keywords: Gloss types, screen cast, vocabulary learning, working memory.

Abstract:

The emergence and the development of new media forms took many diverse directions at the end of the twentieth and the beginning of the twenty first century, significantly influencing many areas of everyday life, as well as contemporary architectural practice. New types of architectural space emerged, types that are based on both new media and architectural principles. These spaces are screen, interactive, kinetic, biotechnological, as well as environments of light. These kind of environments gained new principles and features well known in new media field. Especially important for architectural context is the great potential of new media to create illusions and simulations, to produce augmented and composite, virtual realities and spaces. Virtual space represents one of the most challenging form of new media spaces. It is also the most complex form of screen media environments, so complex that it has taken its own, radical course. Besides the most advanced and complex, screen media interfaces also represent the oldest and typical forms of media architecture. This article will analyze emergence of screen interfaces in architecture, discuss their forms and modalities and examine their influence on human impression of space.

The possibility of using different types of mulch to improve the bulb yield of shallot (Allium cepa var aggregatum) is observed in this paper. The field experiment compared five different types of mulches, including silver, black, straw, screen nylon, and clear plastic mulches, with a non-mulch as a control treatment. Straw mulch and screen nylon mulch reduced shallot biomass but did not significantly affect bulb yield than the control treatment. At the same time, clear plastic mulch increased fresh bulb yield significantly by 30% from 10.26 t ha-1 to 13.29 t ha-1.

APPEA Journal 55, no. 2 (2015): 476. http://dx.doi.org/10.1071/aj14111.

Full text

Abstract:

Sand screens are often installed in sanding prone wellbores to control sand production. A selection of optimal sand screen apertures is required to minimise sand production and maximise fluid production. This has been accomplished historically on empirical correlations, rules of thumb and laboratory sand retention experiments. These methodologies have a number of limitations that can lead to different screen types and sub-optimal screen apertures to be selected. Using discrete element models (DEMs), many design/operating parameters similar to a specific wellbore condition can be simulated and tested in parallel. Most importantly, the detailed particle scale information helps to give a detailed understanding of the underlying mechanisms controlling the sand retention process. This extended abstract presents an investigation of the sand production problem from wire wrapped screens and slotted liners through the use of a DEM for the solid flow with fluid flow coupling using computational fluid dynamics (CFD). Information about particle sizes and distributions incorporated in the DEM model are based on measurement data from reservoir sands. The focus is on the effect of particle size distributions, particle concentration, and the slot width on sand retention across a slotted sand screen.

Abstract To identify novel genes and to isolate tagged mutations in known genes that are required for the development of the peripheral nervous system (PNS), we have screened a novel collection of 2460 strains carrying lethal or semilethal P-element insertions on the third chromosome. Monoclonal antibody 22C10 was used as a marker to visualize the embryonic PNS. We identified 109 mutant strains that exhibited reproducible phenotypes in the PNS. Cytological and genetic analyses of these strains indicated that 87 mutations affect previously identified genes: tramtrack (n = 18 alleles), string (n = 15), cyclin A (n = 13), single-minded (n = 13), Delta (n = 9), neuralized (n = 4), pointed (n = 4), extra macrochaetae (n = 4), pospero (n = 3), tartan (n = 2), and pebble (n = 2). In addition, 13 mutations affect genes that we identified recently in a chemical mutagenesis screen designed to isolate similar mutants: hearty (n = 3), dursotonals (n = 2), pauarotti (n = 2), sanpodo (n = 2), dalmatian (n = 1), missensed (n = 1), senseless (n = 1), and sticky chl (n = 1). The remaining nine mutations define seven novel complementation groups. The data presented here demonstrate that this collection of Pelements will be useful for the identification and cloning of novel genes on the third chromosome, since >70% of mutations identified in the screen are caused by the insertion of a Pelement. A comparison between this screen and a chemical mutagenesis screen undertaken earlier highlights the complementarity of the two types of genetic screens.

Abstract:

The aim of this study is to investigate the use of computational fluid dynamics (CFD) to predict the solid separation efficiency of a hydrodynamic separator. The numerical difficulty concerns the discretization of the geometry to simulate both the global behavior and the local phenomena that occur near the screen. In this context, a CFD multiscale approach was used: a global model (at the scale of the device) is used to observe the hydrodynamic behavior within the device; a local model (portion of the screen) is used to determine the local phenomena that occur near the screen. The Eulerian–Lagrangian approach was used to model the particle trajectories in both models. The global model shows the influence of the particles' characteristics on the trapping efficiency. A high density favors the sedimentation. In contrast, particles with small densities (1,040 kg/m3) are steered by the hydrodynamic behavior and can potentially be trapped by the separator. The use of the local model allows us to observe the particle trajectories near the screen. A comparison between two types of screens (perforated plate vs expanded metal) highlights the turbulent effects created by the shape of the screen.

Abstract:

The article is devoted to the justification of the use of noise protection structures with high noise – absorbing properties to reduce traffic noise. Traffic noise has a negative impact on human health and the environment, so it is necessary to implement measures to reduce its level, including the use of noise protection structures. Noise protection structures are used to protect residential buildings from traffic noise and are classified according to various criteria: stage of road design, type of structure, height, material, position of structures in the transverse profile, longitudinal profile and acoustic properties for sound reflection and absorption. In terms of acoustic properties, noise protection structures are divided into noise-reflecting and noise-absorbing screens. The characteristics of noise-reflecting and noise-absorbing screens and features of their application on highways are considered. It is shown that the sound energy from the noise-reflecting screens is reflected in the opposite direction from the protected object; the noise-absorbing screens do not cause an increase in noise on the opposite side of the road and in the cabins of passing cars due to sound energy absorption. Methods for determining the acoustic efficiency of noise protection screens of different types are presented. A comparative evaluation of the acoustic efficiency of noise-reflecting and noise-absorbing screens was performed, which confirmed the higher acoustic efficiency of noise-absorbing screens. It is shown that with the same characteristics of the noise source in the range of levels 70–100 dB under the condition of four reflections of sound in the system “vehicle – screen” the noise level behind the noise-absorbing screen will be less by about 5 dB than the noise level behind the noise-reflecting screen. Keywords: transport noise, noise protection screen, noise reflection, noise absorption, acoustic efficiency.

Abstract:

The situation with the metrological assurance of brightness measurements in Ukraine is analyzed. The main regulatory documents for the characterization of lux meters are considered. It was noted, that the components of the uncertainty of brightness due to the difference in the spectral composition of radiation, during calibration and measurement, as well as uncertainties due to spatial heterogeneity of the screens, are not fully considered. The characteristic values of these uncertainties are calculated by the method of mathematical modeling, using generally accepted calculation methods. To calculate the spectral errors, the literature data on the spectra of CCFL and LED monitors were used, as well as the modeling of the spectra of blue, green and red radiation sources, using Gaussian distribution with varying widths. It is shown, that for а brightness meter calibrated by а type A source, the use of white screens for measuring the brightness will result in errors, less than 7%. It is shown, that when calibrating the brightness meter using the CCFL screen and then using the LED for the screen, the errors will be about 1%. Simple formulas are given to evaluate the effect of screen heterogeneity. For а refined assessment of the influence of spatial inhomogeneity, mathematical modeling was carried out — 3 types of brightness distribution, were used with decreasing radiation distribution density and two types of viewing area — а circle (imitation of brightness measurement, using а diaphragm) and а Gaussian distribution (imitation of brightness measurement with а lens) equal widths. It is shown, that for the field of sight in the form of а Gaussian distribution, the influence of the inhomogeneity of the distribution of screen illumination, when moving and changing the width of the field of sight is insignificant. Two approaches have been proposed for building the material base for metrological assurance of brightness measurements.

Abstract:

Analysis of effectiveness of two types of net systems protecting vehicles against projectiles with cumulative (shaped charge) warhead is presented in the article. Numerical models of net screens and PG7-WM projectile were created to simulate projectile penetration into the screen. Numerical analyses were used to determine a maximal distance in radial direction from projectile axis for which screen elements should come into contact with the projectile to neutralize it. Determined distances were used to calculate the probability of neutralization of pro-jectiles by net systems. Calculations were performed for elevation and azimuth angles of α = 0÷45°. The values calculated in such way were used to make graphs of PG-7WM projectile neutralization probability for both types of net systems in function of mesh size and azimuth and elevation angles at various mesh sizes. Received results may be used to optimize geometries of net systems to in-crease effectiveness of projectile neutralization.

This paper presents the study results regarding the analysis of the screen printing quality on different types of materials. The quality of the screen printing is determined by several particularities of the screen printing process such as: the type of mesh, screen ruling, ink viscosity, raster spacing, etc. The material which is supposed to be printed is as important as the particularities of the screen printing process itself. The composition, structure and features of the printed items as well as the composition, viscosity and other ink properties, all together determine the quality of the screen printed matter.

Abstract:

Recent technological advances in microscopy have enabled cell-based whole genome screens, but the analysis of the vast amount of image data generated by such screens usually proves to be rate limiting. In this study, we performed a whole genome RNA interference (RNAi) screen to uncover genes that affect spreading of Drosophila melanogaster S2 cells using several computational methods for analyzing the image data in an automated manner. Expected genes in the Scar-Arp2/3 actin nucleation pathway were identified as well as casein kinase I, which had a similar morphological RNAi signature. A distinct nonspreading morphological phenotype was identified for genes involved in membrane secretion or synthesis. In this group, we identified a new secretory peptide and investigated the functions of two poorly characterized endoplasmic reticulum proteins that have roles in secretion. Thus, this genome-wide screen succeeded in identifying known and unexpected proteins that are important for cell spreading, and the computational tools developed in this study should prove useful for other types of automated whole genome screens.

Abstract:

Abstract Systematic perturbation screens provide comprehensive resources for the elucidation of cancer driver genes. The perturbation of many genes in relatively few cell lines in such functional screens necessitates the development of specialized computational tools with sufficient statistical power. Here we developed APSiC (Analysis of Perturbation Screens for identifying novel Cancer genes) to identify genetic drivers and effectors in perturbation screens even with few samples. Applying APSiC to the shRNA screen Project DRIVE, APSiC identified well-known and novel putative mutational and amplified cancer genes across all cancer types and in specific cancer types. Additionally, APSiC discovered tumor-promoting and tumor-suppressive effectors, respectively, for individual cancer types, including genes involved in cell cycle control, Wnt/β-catenin and hippo signalling pathways. We functionally demonstrated that LRRC4B, a putative novel tumor-suppressive effector, suppresses proliferation by delaying cell cycle and modulates apoptosis in breast cancer. We demonstrate APSiC is a robust statistical framework for discovery of novel cancer genes through analysis of large-scale perturbation screens. The analysis of DRIVE using APSiC is provided as a web portal and represents a valuable resource for the discovery of novel cancer genes.

There are different types of lighting systems suitable for VDT work, which create different interior appearances with respect to the main lighting parameters at the recommended levels at the same time. A new generation of VDT screens, flat panels, which produce the image on the screen in a completely different way, may demand different lighting conditions than CRT screens. The aim of the study was to model different lighting systems for VDT work with LCD screens and their influence on the users' preferences and visual performance. The results of the study showed that the most preferred lighting system for VDT work with LCD screens is direct lighting realized by “dark-light” luminaires.

Abstract:

This study explored how telepresence could be affected by stimuli from reality that distracts people while they are watching television. The sample comprised of 36 undergraduate and graduate students from a university in South Korea (age range: 18–38 years, M = 22.61, and SD = 4.12). A between-subjects experimental design was employed with two types of viewing equipment (a television screen vs. a television screen with side screens that act as stimuli from reality) and two bezel widths (2 cm vs. 10 cm) to examine how each condition influenced the viewers’ perceived telepresence. The results revealed that participants’ perception of telepresence was not affected by the type of viewing equipment. However, the level of telepresence was affected by the bezel width: the thinner the bezel, the more telepresence felt by the viewers. These findings provide important insights that can guide the future designs of screen bezels for televisions and other devices in order to more effectively create immersive virtual worlds. Future studies are needed to examine the relationship between central vision and telepresence.

Abstract:

Background: This study was done with the objective of finding the average daily duration and pattern of screen time use in children in the age group of 24 to 60 months in the state of Tamilnadu, India and to find the correlation between screen time and demographic parameters.Methods: This cross-sectional observational study was conducted at the state of Tamilnadu, India from June 2019 to August 2019 among 148 children in play school and kindergarten classes in the age group of 24 to 60 months fulfilling the inclusion and exclusion criteria. Details regarding screen time use were collected from the parents using a predesigned questionnaire and analyzed using suitable statistical methods.Results: A total of 148 children (77(52.0%) male and 71(48.0%) female) were studied. The average daily screen time in the study group was 139.4 minutes (SD: 1.6). Majority of the children had a screen time duration between 61 to 120 minutes (48.6%). Only 14.2% had a screen time of ≤60 minutes as per AAP and WHO recommendations. Majority of the screen time was used to watch children’s entertainment programs and play games (67.6%). 83.1% of the children were using 2 or more screen types. Television and smart phones were the commonest screen types used by children in this age group. The percentage of children with average daily screen time ≤ 60 minutes was found to be more in joint families (16.3%) compared to nuclear families (10%). But this difference was not statistically significant. No statistically significant correlation was found between screen time duration in children and age, gender, parent’s socioeconomic status, education and occupation.Conclusions: Increasing screen time activity in early childhood is an emerging problem of the digital age which requires interventions at family, social and healthcare levels.

Abstract:

The advantages of autogenerator displacement transducers in track control systems of metal – cutting machines, industrial robots, robotic complexes and flexible automated productions, such as high speed and durability of control systems, as well as their disadvantages-the lack of sufficiently complete accuracy characteristics, which affects the efficiency of equipment with track control systems, are considered. Formulated the research problem and described a special experimental setup, which studied the sensitivity of the self displacement transducers three types based on their mutual arrangement and screens of various metals (iron, steel 45, steel St3, 12KH18N10T steel, brass, dural and copper), as well as the conditions of their operation depending on the positioning of screens. The results of experimental data processing are presented, and any dependence of sensitivity on the screen material is not established. The assumption about the randomness and insignificance of the revealed differences is put forward and verified, and it is shown by the Cochran criterion that they are rightfully considered insignificant with a reliability of at least 95 %. The influence of power supply voltage fluctuations in the network on the accuracy characteristics of auto-generator displacement converters is studied and the results of the research are presented. A statistical test was carried out using the student’s criterion, which showed the absence of this influence on the accuracy characteristics. It is noted that hysteresis occurs during the operation of autogenerator displacement transducers and it is experimentally established that in most cases it increases with the transition from a diamagnetic screen to a ferromagnetic one. It is proposed to use the results of the research of precision characteristics in the design and efficient operation of the system limit control on the basis of self converters of displacements of the considered types, addressing issues about the need to use the voltage regulator when selecting screen material, etc.

Abstract:

The cultivation of ornamental plants under different types of shelter and covering materials which reduce light intensity, resulting in morphological and physiological changes, needs to be evaluated before any large-scale use of such types of shelter covers. Baby rubber plants were grown in pots filled with peat under four different shelters and covering materials as follows: MG (multitunnel greenhouse with thermo-reflective aluminised screen), BG (buried solar greenhouse with thermo-reflective aluminised screen), NH (net house covered only with antipest mesh) and NH-AS (net house with antipest mesh and thermo-reflective aluminised screen). At the end of the experiment, the growth parameters and color of leaves, as well as photosynthetic and nutritional parameters, were assessed for each treatment. Baby rubber plants grown under NH-AS showed the highest values for growth parameters. The absence of shading in a net house may result in photoinhibition, reducing the growth and increasing the values of red (R) and blue (B) in leaves, which may be related to the increase of anthocyanin synthesis. The low level of radiation intercepted in the multitunnel and the buried greenhouse increased chlorophyll, N and P leaf concentration, while for K concentration, there was no clear trend and Na and Cl leaf concentration were similar under the different types of shelter. We concluded that the production of baby rubber plants under net house with antipest mesh and thermo-reflective aluminised screen is the best option to maximise the market value of baby rubber plants.

ABSTRACT The objective of this study was to evaluate the performance of three models of drippers using treated sewage effluent, pure and diluted, and two types of filters, screen and disc. The treated sewage effluent used in the experiment was collected from the city’s treatment plant. The experiment included 12 lateral lines with three types of emitters to apply pure (100%) and diluted (50%) effluent filtered by screen and disc filters. The combination of those factors set the treatments: T1 (50% effluent diluted in fresh water filtered by a screen filter); T2 (50% effluent diluted in fresh water filtered by a disc filter); T3 (pure effluent filtered by a screen filter); T4 (pure effluent filtered by a disc filter). The results showed that the flat type emitter is less sensitive to clogging, the disc filter is the most suitable to prevent clogging and the use of pure or diluted sewage effluent increases the drippers’ flow rate coefficient of variation.

Abstract:

Purpose Despite the increasing demand for socially responsible investments (SRIs) and the importance of information intermediaries in providing corporate social responsibility (CSR) performance information through SRI screens, relatively little is known about the relationship between nonprofessional investors’ views regarding SRI, their use of SRI screens and their actual SRI behavior. This study aims to distinguish between investor views about the importance of corporate environmental responsibility (environmental performance importance views) and whether they view environmentally responsible firms as yielding higher returns (environmental performance return views). It examines the association between these views, SRI screen use and reported SRI holdings. Design/methodology/approach Nonprofessional investor participants completed an online survey about their SRI investment views, screen use and investment behavior. The survey yielded 201 usable responses. Findings The strength of participants’ environmental performance importance and environmental performance return views is positively associated with their use of SRI screens and the proportion of their portfolios held in SRIs. SRI screen use only partially mediates the association between investors’ environmental performance importance and return views and their SRI holdings. Research limitations/implications The study does not precisely address what types of SRI screens nonprofessional investors may be using. It does not control for investors’ specific experience with SRIs, nor does it examine how or why investors come to believe that environmental responsibility may improve a company’s return potential. Practical implications The fact that SRI screen use only partially mediates the association between investors’ views and their SRI holdings suggests that either reliable, unfiltered CSR information is important for nonprofessional investors or some investors are choosing SRIs without obtaining adequate relevant information. Social implications The study’s findings confirm earlier research findings which show an association between investors’ pro-environmental views and their decision to invest in SRIs (Williams, 2007; Nilsson, 2008) and suggest that nonprofessional investors are becoming aware of the positive relation between environmental performance and firm value (Dhaliwal et al., 2011; Clarkson et al., 2013; Hawn et al., 2014; Matsumura et al., 2014). Originality/value This study simultaneously examines the influence of environmental performance importance (an “alternative” investment perspective) and environmental performance return (a “traditional” investment perspective) on investors’ SRI behavior.

Abstract:

This paper presents sources and types of corrosion processes of boiler tube system of the Thermal Power Plant "Ugljevik". The main goal in the electric power production is to achieve lower prices, which can only be done by providing low maintenance costs. While it is not possible to completely stop corrosion, it could be slowed down and it's effects could be reduced. In order to reduce corrosion to a minimum on thermal power plants' vital equipment, particularly boilers, it is necessary to determine in each particular case the acting mechanism of corrosion and agents that cause it. Damages and failures on thermal power plants are largely caused by the development of various types of corrosion processes. Special attention is given to the preparation of water, considering its importance to the occurrence of corrosion. The following types of corrosion were detected on the screen tube boiler by visual examination on the side of water and steam: erosive, pitting and impact corrosion. The inner surface of screen pipes, from which the scale layer was removed, indicates that the erosive corrosion with the thinning of pipe walls occurs. Perforation of the welded screen pipes shows that stress corrosion occurred on the screen pipe with formation of cracks and that pipe exploded. Pits on the inner surface of the screen pipes, visible after the removal of scale and corrosion products, are proof that pitting corrosion occurred. The causes of corrosion were discovered and proposed measures for their elimination were given.

Abstract:

Hydrodynamic separators (HDSs) have been used extensively to reduce stormwater pollutants from urbanized areas before entering the receiving water bodies. They primarily remove particulates and associated pollutants using gravity settling. Two types of HDSs with different structural configurations of the inner vortex-inducing components were presented in this study. One configuration consisted of a dip cylindrical plate with a center shaft while the other one has a hollow screen inside. With the help of computational fluid dynamics, the performance of these different types of HDSs have been evaluated and comparatively analyzed. The results showed that the particle removal efficiency was better with the cylindrical plate type HDSs than the screen type HDSs because of the larger swirling flow regime formed inside the device. Plate type HDSs were found more effective in removing fine particles (∼50 μm) than the screen type HDSs that were only efficient in removing large particles (≥250 μm). Structural improvements in a HDS such as increase in diameter and angle of the inlet pipe can enhance the removal efficiencies by up to 20% for plate type HDS while increase in the screen diameter can increase removal efficiencies of the screen type HDS.

Abstract:

A protection of information against electromagnetic penetration is very often considered in the aspect of the possibility of obtaining data contained in printed documents or displayed on screen monitors. However, many printing devices are equipped with screens based on LED technology or liquid crystal displays. Options enabling the selection of parameters of the printed document, technical settings of the device (e.g., screen activity time) are the most frequently displayed information. For more extensive displays, more detailed information appears, which may contain data that are not always irrelevant to third parties. Such data can be: names of printed documents (or documents registered and available on the internal media), service password access, user names or regular printer user activity. The printer display can be treated as a source of revealing emissions, like a typical screen monitor. The emissions correlated with the displayed data may allow us to obtain the abovementioned information. The article includes analyses of various types of computer printer displays. The tests results of the existing threat are presented in the form of reconstructed images that show the possibility of reading the text data contained in them.

Abstract:

Hence the social life is changing and social interaction is amplified by technology. Therefore, social research would change its approach/es concomitantly. We are living in the age of technology where many people are interacting through social media generally referred to as a screen. Therefore, it is creating the need for innovative screen research methods to study and give meaning to screen interaction. Due to lock-down and restrictions on physical interaction during the COVID-19 pandemic, the screen interaction is intensified. Particularly the community-based organizations, businesses, and academia were observed prone towards using screen interaction approaches. Similarly an International Non-Governmental Organization hereinafter (INGO) in Erbil, Iraq. Started a Facebook page to interact with its beneficiaries to listen to their urgent needs and feedback to project activities. Based on that monitoring and evaluation unit observed a need to monitor screen interaction between organization and community. Hence, the innovative approaches of screen survey and screen sampling were identified. To conduct an intermittent screen survey it was important to select a relevant sampling method. In general, there are two schools of sampling in social sciences. Probability sampling and non-probability sampling. Under probability sampling, each individual has the right to be selected as a participant in a study. Under non-probability sampling, participants are selected based on certain criteria that are relevant to the domain of study. Both schools of sampling have many types and sub-types selected as per the specifications of a study. Therefore, the Intermittent Screen Review Sampling (ISRS) method was developed based on precedent theoretical work. The screen survey refers to the collection and analysis of responses of viewers of any specific social media page. Where respondents are not asked to participate or share their feelings or thoughts. Respondents voluntarily appear on the screen and interact with any post and reflect their thoughts. Henceforth, the surveyors collect these displayed thoughts intermittently, do some analytical work, and produce meaning out of these emojis, shares, memes, and comments. Quantitative and qualitative analyses were conducted within the context of the post/s shared by authorized person/s on a social media official page. Thereafter, the results were presented in quantities and narrations. This research paper is developed to communicate these innovative approaches of semi-analytical screen survey and intermittent screen review sampling at a wider level. This research would pave a way for further screen studies and innovations that are the needs of our screen generation.

Abstract:

This paper outlines the complexity of accounting for multilingual audiovisual films for the purpose of their translation. In particular it focuses on an issue that has not received much scholarly attention so far, the fictional representation of code-switching in feature films, with particular attention to Spanglish, given that language and its interlinguistic barriers towards interpersonal communication is one of the main themes of the film. The paper distinguishes different types of language shifts (alternations) as part of a film’s plot or script, like straightforward translation between characters, in order to better characterize code-switching as concept borrowed from sociolinguistics. This, in turns allows for a broader notion of language shifts, of which code-shifting is a part. Finally, the paper also includes a three-type classification of films depending on the amount and importance of languages other than the main language of a film: anecdotal, recurrent, and L3-as-theme, L3 being the notation system used to label all instances of languages in a text (written, oral or audiovisual) other than the main language.
