Full textAbstract:
The concept of time is deeply rooted within the field of literature; not only does it present itself in literary works in the form of theme or symbol. It can also be viewed in the reflection of the time in which the piece was written; but, most importantly in the context of this paper, it plays an essential and indispensable role as a plot device when constructing the narration. The modification of these expressions of time varies in accordance with the author’s views and purposes for their literary work. Thus, instances of toying with the base structure of time flow occur. This paper aims to display the employment of time reordering as a plot device in order to conclude whether this manner of writing was beneficial to the works in which it is depicted. This analysis will take into consideration a variety of advantages that time reordering could provide, from adding a sense of mystery, chaos, or irony, to much more intricate plot, structure or even subtext benefits. To be able to encounter all of the mentioned benefits, this paper will discuss a selected number of fictional literary works from the Gothic-like historical novel Hawksmoor by Peter Ackroyd to the contemporary novel The Stone Gods by Jeanette Winterson. The term of time reordering within this paper will refer to the abandonment of a linear plot line and the approach of multiple timelines or a hazardous presentation of events.

The seed metering device is the key working part of the peanut planter and is placed above the bottom of the seed box or above the opener. The essence of the seed metering process is the eff ect of the seed meter on the seed, converting the seed from the population into an individual, and converting it into a uniform seed stream or a continuous single seed. The seeding method and quality of the seeding machine depend mainly on the seed metering device. Aiming at the shortage of re-broadcasting rate and missed-out rate during sowing, the diff erent parameters of the air-suction metering device were analyzed, and the seeding performance of the seeding device was tested to obtain the primary and secondary factors aff ecting the performance of the seeding device, and the quality of seeding was improved.

Background Wellness devices for health tracking have gained popularity in recent years. Additionally, portable and readily accessible wellness devices have several advantages when compared to traditional medical devices found in clinical environments The VitalWellness device is a portable wellness device that can potentially aide vital sign measuring for those interested in tracking their health. Objective In this diagnostic accuracy study, we evaluated the performance of the VitalWellness device, a wireless, compact, non-invasive device that measures four vital signs (blood pressure (BP), heart rate (HR), respiratory rate (RR), and body temperature using the index finger and forehead. Methods Volunteers age ≥18 years were enrolled to provide blood pressure (BP), heart rate (HR), respiratory rate (RR), and body temperature. We recruited participants with vital signs that fell within and outside of the normal physiological range. A sub-group of eligible participants were asked to undergo an exercise test, aerobic step test and/or a paced breathing test to analyze the VitalWellness device’s performance on vital signs outside of the normal physiological ranges for HR and RR. Vital signs measurements were collected with the VitalWellness device and FDA-approved reference devices. Mean, standard deviation, mean difference, standard deviation of difference, standard error of mean difference, and correlation coefficients were calculated for measurements collected; these measurements were plotted on a scatter plot and a Bland-Altman plot. Sensitivity analyses were performed to evaluate the performance of the VitalWellness device by gender, skin color, finger size, and in the presence of artifacts. Results 265 volunteers enrolled in the study and 2 withdrew before study completion. Majority of the volunteers were female (62%), predominately white (63%), graduated from college or post college (67%), and employed (59%). There was a moderately strong linear relationship between VitalWellness BP and reference BP (r=0.7, P<.05) and VitalWellness RR and reference RR measurements (r=0.7, P<.05). The VitalWellness HR readings were significantly in line with the reference HR readings (r=0.9, P<.05). There was a weaker linear relationship between VitalWellness temperature and reference temperature (r=0.3, P<.05). There were no differences in performance of the VitalWellness device by gender, skin color or in the presence of artifacts. Finger size was associated with differential performance for RR. Conclusions Overall, the VitalWellness device performed well in taking BP, HR, and RR when compared to FDA-approved reference devices and has potential serve as a wellness device. To test adaptability and acceptability, future research may evaluate user’s interactions and experiences with the VitalWellness device at home. In addition, the next phase of the study will evaluate transmitting vital sign information from the VitalWellness device to an online secured database where information can be shared with HCPs within seconds of measurement.

Full textAbstract:
For the chemical protection of orchards, a research on the surface area of 150 ha was carried out, and a method of spraying was applied. In this method, machines known as orchard sprayer are used, in which, in the presence of the produced air current, liquid disintegration is also carried out at a drop size of 50 to 150 μm. The aim of the research is to improve the precision of work within the control of the device, where the emphasis on the nozzle capacity is primarily augmented, and therefore increases the productivity of the device. The results obtained on the basis of a 10-hour working time prove that the exploitation of the controlled orchard sprayer ensures greater productivity by 2.24 ha on a plot distanced 50 m from the location of the tank refill, i.e., 2.20 ha on a plot distanced 2000 m from the location of the tank refill, for the drawn sprayer of 1.000 l volume. By analyzing the total energy inputs of orchard protection, different application models point to a smaller energy input when using controlled devices on a 50 m range for 7.58%. Energy inputs on a longer distance plot are by 24.68% lower in favor of the treatment of controlled sprayer.

Abstract The absence of an appropriate mechanization technology for lower stages of field breeding experiment is a common problem in seed research industry. This study was focused on the development of a corn plot seeder to be used in planting corn seeds for lower stages of field breeding experiments. The machine was equipped with mechatronic seed feeding device to provide an efficient way of sowing for every plot. Field testing and cost analysis between the Corn plot seeder and two other seeders were conducted to determine the performance and economic viability. Results showed that the Corn plot seeder can sow seeds at 0.49 ha/day with a field efficiency of 42.46 %. Its row/hill spacing was also at the optimum values of 70 ± 3 cm and 21 ± 4 cm respectively. It was able to sow 1 ± 1 seeds per hill and generated a 93% planting efficiency with a 7% missed hill. The Corn plot seeder had the highest capital investment of Php 27,380.00 but had the cheapest annual operating cost of Php 27,963.36. The push type corn plot seeder with mechatronic seed feeding device was the most efficient and economical machine for lower stage corn field breeding experiment.

Background [Please check the following sentence for clarity: “Point-of-care devices measuring international normalized ratio have clinical appeal, reports of ‘off-label’ in-hospital/primary care use report improved time to intervention/dose adjustment.”]Point-of-care devices measuring international normalized ratio have clinical appeal, reports of ‘off-label’ in-hospital/primary care use report improved time to intervention/dose adjustment. We evaluated the accuracy and precision of a device for such multiple patient use compared to a reference laboratory. Methods The point-of-care international normalized ratio result of patients on oral anticoagulation at the Vascular Surgery clinic was compared to the reference to check for statistical and clinical correlation. This was a prospective case–control study design with sample size calculated for sensitivity of 87.5%, precision 5% and desired confidence level 95%. Results There were 168 patients tested; 55% were male, the mean age was 45.4. Sixty per cent were in the target international normalized ratio range. Tests were done for statistical and clinical correlation. The international normalized ratio range using the point-of-care device was 0.8–7.5 (reference lab 0.8–10), mean international normalized ratio was 2.22 ± 1.6 (point-of-care device) compared to 2.46 ± 1.3 (reference lab). The mean absolute difference was 0.79 ± 0.92 and the mean relative difference was 8.1% ± 1.03. Data was analysed using a Bland–Altman plot yielding a mean of 0.738 (standard deviation 0.92). Concordance between the tests was 75% with r2 = 0.52 on linear regression. Using an error grid plot, excellent clinical correlation was seen in 63.8%. In 5.4% major corrective action was needed but potentially missed if relying on the point-of-care device. Conclusion The accuracy and precision of this point-of-care device is moderate. It may have potential utility only where access to a reference lab is difficult.

Full textAbstract:
In order to solve the problems of easy-to-break kernels and substantial harvest losses during kernel harvesting in breeding trials plot of corn, an ear-picking device and a threshing device of corn plot kernel harvester has been optimized. To automatically change the gap of the ear-picking plate, a self-elastic structure with compression spring and connecting rod is used. The ear-picking plate is glued, and an elastic rubber gasket is placed underneath it, which effectively improves the adaptability of the ear-picking device and reduces corn kernel collision damage during ear-picking. To ensure the self-purification of the ear-picking device, a combination of auger sieve hole cleaning device and lateral pneumatic auxiliary cleaning system is used. A dual-axial flow threshing device is designed, which uses a “U”-shaped conveying system to transport maize ears in the threshing chamber. The spacing of the concave sieve may be adjusted, and the residual kernels in the threshing chamber can be cleaned up after harvesting one plot by combining three cleanings, which meets the requirements of no mixing between plots. The force analysis of corn ears in the threshing chamber determines the best design plan for the forward speed, the speed of the second threshing drum, and the threshing gap. The breakage rate and non-threshing rate regression models were created using the quadratic regression orthogonal combination test, and the parameters were optimized using MATLAB. The verification test results showed that when the forward speed was 0.61 m/s, the second threshing drum speed was 500 r/min, and the threshing gap was 40 mm, the breakage rate was 1.47%, and the non-threshing rate was 0.89%, which met the kernel harvesting requirements in corn plots.

Full textAbstract:
Unique among other rhetorical devices, wit can appear complex and banal simultaneously. The clever language can express thought equal to the weight of lengthy discourse in a few words, often with amusing effect. However, despite the complexity of the device, wit only offers a momentary chuckle or clarification of events, easily forgotten in a larger context. This dichotomy of wit operates the plot and theme in many literary texts. Intelligent protagonists employ the device to remedy their problems, believing that the complexity of the response ensures its effectiveness. However, because wit consists of only words, the device falls short of enacting change that action or direct discourse could more appropriately handle. This paper examines the role of wit in Hamlet and Catch-22 to determine how characters rely on wit to affront their problems but succeed only in amplifying them.

Full textAbstract:
Present work has studied potential barrier of Phenosafranin dye based organic device and has observed influence of different concentrations of titanium dioxide nanoparticles on this parameter. We have made different devices by taking different weight ratios of the dye – nanoparticles blend which are 1:1, 1:2, 1:3 and 1:4. These organic devices have been formed by varying the concentrations of titanium dioxide nanoparticles keeping same dye content. One device is also formed without any nanoparticle to compare influence of nanoparticle on potential barrier of the device. These devices are formed by sandwiching the dye – nanoparticle blend in between the Indium Tin Oxide coated glass and Aluminium coated mylar sheet. The potential barrier is measured from device’s I-V plot and also by Norde function. These two methods remain in good agreement showing that potential barrier is mostly decreased when the concentration of the titanium dioxide nanoparticles is highest in the blend of Phenosafranin dye and titanium dioxide nanoparticles. The ratio of dye –nanoparticle blend of 1:4 shows lowest potential barrier and it is highest when Phenosafranin dye based organic device is made without any nanoparticle. The reduced potential barrier in the presence of higher concentration of nanoparticles can be ascribed to improved filling of traps. Lowered potential barrier at metal – organic contact will improve the charge flow resulting in better performance of the device.

Full textAbstract:
Background Wellness devices for health tracking have gained popularity in recent years. Additionally, portable and readily accessible wellness devices have several advantages when compared to traditional medical devices found in clinical environments. Building tools for patients to manage their health independently may benefit their health in the long run by improving health care providers’ (HCPs) awareness of their patients’ health information outside of the clinic. Increased access to portable wellness devices that track vital signs may increase how patients and HCPs track and monitor chronic conditions which can improve health outcomes. The VitalWellness is a portable wellness device that can potentially aid vital sign measuring for those interested in tracking their health.

Full textAbstract:
Nineteenth-century Protestant culturegenerally held marriage in high esteem, and the notion that marriage was “made in heaven” often explicitly undergirds the conventional resolution of domestic fiction. Despite many indications of a harmonious relationship between human love and religious faith, a countervailing cultural trend reveals a deep conflict between the two. Victorian Protestants worried that passionate love for another mortal creature might lead to heretical extremes, that human love might slip into idolatry, the worship of false and material gods. Jane Eyre memorably confesses that she has “made an idol” of Rochester, although she, of course, looks back upon this transgression from the vantage of marital happiness (274). In this essay, I focus on works in which misgivings about idolatrous love arise with more disruptive force. The marriage plots of Charles Kingsley'sYeast: A Problem(1851) and Charlotte Brontë'sVillette(1853) both abruptly collapse, bringing into sharp focus a Protestant religious anxiety that subverts the conventional device with which Victorian domestic novels achieve closure.

Full textAbstract:
For the study of soil erosion it is important to set up the experiments well. In the experimental design one of the key factors is the choice of the measurement device. This is especially important when one part of the erosion process needs to be isolated, such as for splash erosion. Therefore, the main aim of this research is to list the general characteristics of the commonly used splash erosion devices and to discuss the performance, to be able to relate them, and make suggestions regarding their use. The devices we selected for this comparative comparison were: the splash cup, funnel, Morgan tray, Tübingen cup, tower, and the gutter. The devices were tested under the same conditions (rainfall characteristics, slope, and soil type) to assess their hydrological response under different intensities of simulated rainfall. All devices were installed on a sloping plot (10°) with sandy soil, and were exposed to 10 min. of simulated rain with intensities ranging from 60 to 172 mm/h to measure the splashed sediment, and to describe problems and differences among them. The results showed that the Tübingen cup was the best performing device to measure kinetic energy of the rain, but, because of its design, it is not possible to measure the detached splashed sediment under natural (field) conditions. On the other hand, the funnel device showed a significant relation with rain intensity because it loses little sediment to washing. In addition, the device is easy to use and cheap. Therefore, this device is highly recommended to estimated splash erosion. to the good performance measuring the actual splash erosion, because it loses little sediment by washing. The device is also cheap and easy to install and manage.

Full textAbstract:
Hayavadana, a multiplex play, offers various binary themes for discussion. By combining the indigenous Yakshagana and the western Brechtian Epic theatre practices, Girish Karnad has created a unique theatre display, presenting it as a social and religious satire that point to the persistent pursuit of the humanity to achieve perfection. The plot and the sub-plot of the play get interlocked by raising questions on identity and the nature of reality. The dramatist intentionally effects a dynamic communication between the audience and the performance, noting that the audience too are not separate from such an existential predicament. This Verfremdungseffekt or the “alienation effect”, is achieved through a number of devices. One such device, apart from the folk-theatre motifs, is the philosophical survey of the concepts, ‘Sacred’ and the ‘Profane’. This paper ventures to show how these concepts add further investigation of the play.

Full textAbstract:
Digression is a notable literary device that conveys a temporary departure from the main part of the narrative to focus on unrelated issues explaining the background details. However, after the temporary move, the author returns to the central topic at the end of the narrative. In his remarkable novel Joseph Andrews, Henry Fielding used various digressive or interpolated materials that add variety to the main plot. Here, Fielding deploys digression not as an exaggerated statement but rather as a part and parcel of the main plot. Such digressive or interpolated materials were expected to be related to the main plot by theme, moral, symbolic or ironic inverse relationship.

Abstract Charge transfer (CT) state is a key intermediate to understand recombination processes in organic solar cells (OSCs). In this study, we measured the recombination emission from the CT state under different applied voltages in OSCs and a photocurrent density flowing on the circuit simultaneously. We proposed a “photoluminescence (PL)–voltage (V) plot” that is the voltage dependence of PL intensity of the CT state. The PL–V plot includes information only from the CT state recombination at the donor/acceptor interface and is complementary to the “current density (J)–V plot” that is the most important information for evaluating OSCs. The results demonstrated that the fill factor (FF) of the PL–V plot is higher than that of the J–V plot, predicting the ideal FF of the device. Our result demonstrated that the simultaneous measurement of photocurrent and recombination emission could be a strong tool for evaluating photoconversion characteristics in OSCs.

Full textAbstract:
The current gain degradation of 4H-SiC BJTs with no significant drift of the on-resistance is investigated. Electrical stress on devices with different emitter widths suggests that the device design can influence the degradation behavior. Analysis of the base current extrapolated from the Gummel plot indicates that the reduction of the carrier lifetime in the base region could be the cause for the degradation of the gain. However, analysis of the base current of the base-emitter diode shows that the degradation of the passivation layer could also influence the reduction of the current gain.

Molecular Quantum-dot Cellular Automata is the most promising and challenging technology nowadays for its high operating frequency, extremely high device density and non-cryogenic working temperature. In this paper, we report a First Principle approach based on analytical model of 3-dot Bio Molecular Quantum-dot Cellular Automata. The device is 19.62Å long and this bio molecular Quantum dot Cell has been made with two Adenine Nucleotide bio-molecules along with one Carbazole and one Thiol group. This whole molecular structure is supported onto Gold substrate. In this paper, two Adenine Nucleotides act as two quantum dots and Carbazole acts as another dot. These 3-Quantum-dots are mounted in a tree like structure supported with Thiol group. This model has been demonstrated with Extended Hückel Theory based semi-empirical method. The quantum ballistic transmission and HOMO-LUMO plot support the polarization state change. This state changing ability has been observed for this molecular device. Therefore, this property has been investigated and reported in this paper. HOMO-LUMO plot shows the two logic states along with null state for this 3-dots system. This phenomenon illustrates how the charge transfers take place. Two polarization states along with one additional null state have been obtained for this bio molecular nano device. This molecular device has been operated with 1000THz frequency. This nanoscale design approach will initiate one step towards the modeling of high frequency bio molecular Quantum dot Cell at room temperature.

The population problem is a fairly complex and complicated problem. Therefore, Indonesia seeks to control the birth rate with the Family Planning program. The implementation of this program can be evaluated through statistical data. The statistical analysis used is biplot principal component analysis to see the relationship between districts/cities in choosing the contraceptive device/method used, the variance of each contraceptive device/method, the correlation between contraceptive devices/methods, and the superiority value of the contraceptive device/method in the population. each district/city. The problem with performing the analysis is the limitations of easy-to-use open source software. As with R, users must understand writing code to perform data analysis. Therefore, to perform a biplot analysis of the principal components, an RShiny application has been created using RStudio. The R-Shiny that has been made has many advantages, including complete results which include data display, data transformation, SVD matrix, to graphs along with plot graph interpretation. The results of the principal component biplot analysis using R-Shiny with α =1 have the advantage of a good principal component biplot, which is 95.63%. This shows that the biplot interpretation of the main components produced can be explained well the relationship between the district/city and the contraceptive methods/devices used.

Full textAbstract:
Rainfall simulators are research devices that can be used for studying runoff and sediment transport on the plot scale. This technical note introduces a new solution that combines the two most commonly used methods for generating artificial rain—swinging and pulse jet systems. Reasons for developing this device are its universal use, simple construction, and reduction of water consumption, with better spatial distribution of rain and rainfall kinetic energy close to that of natural conditions. Routine operations of this device are expected for plots of 1 × 1 m, with a height 2–2.5 m. The rained surface could be extended to 2 × 2 m with lower spatial distribution. The sprinkled area in this case was limited by the drain box that also collected the remaining water. The principle of the presented single-nozzle simulator can be extended to multi-nozzle simulators for larger experimental plots.

We investigated differences in body composition measurements for the whole body and limb segments in elite male wrestlers between results of multi-frequency bioelectrical impedance analyses (MFBIA) and dual energy X-ray absorptiometry (DXA). Sixty-six elite male wrestlers from Taiwan were recruited. Wrestlers’ body fat percentage (PBFWB), whole body fat-free mass (FFMWB), whole body lean soft tissue mass (LSTMWB), and fat-free mass of arms, legs and trunk (FMArms, FFMLegs, FFMTrunk) were measured by MFBIA and DXA, and analyzed using Pearson correlation coefficient and Bland–Altman plot. Correlations of FFMWB, LSTMWB, and PBFWB between devices were 0.958, 0.954, and 0.962, respectively. Limits of agreement (LOA) of Bland–Altman plot were −4.523 to 4.683 kg, −4.332 to 4.635 kg and −3.960 to 3.802%, respectively. Correlations of body composition parameters FFMArms, FFMLegs and FFMTurnk between devices in each limb segment were 0.237, 0.809, and 0.929, respectively; LOAs were −2.877 to 2.504 kg, −7.173 to −0.015 kg and −5.710 to 0.777 kg, respectively. Correlation and consistency between the devices are high for FFM, LSTM and PBF but relatively low for limb segment FFM. MFBIA may be an alternative device to DXA for measuring male wrestlers’ total body composition but limb segment results should be used cautiously.

In order to uplift the safety of the device, a gel polymer electrolyte was used instead of a liquid electrolyte. Two identical electrodes were consisted with Sri Lankan natural graphite as the active material and polyvinylidenefluoride as the binder. To prepare the electrolyte, polyvinylidenefluoride co hexafluoropropylene and magnesium perchlorate were used as the polymer and the salt respectively. Cyclic voltammetry test results show that single electrode specific capacitance is depending on the potential window. The percentage reduction of capacitance with continuous cycling was about 28%.

Full textAbstract:
Quantum dot solar cells have received significant attention in comparison to standard solar cells because of their hybrid nature, low production costs, and higher power conversion efficiency. Although quantum dot solar cells (QDSCs) have several benefits over ordinary solar cells, their performance lags due to carrier combination within the quasi-neutral region (QNR). The electron transport layer (ETL) and hole transport layer (HTL) are the two layers that have the most effect on QDSC performance. This numerical analysis is carried out by using the Solar Cell Capacitance Simulator-1 dimensional software (SCAPS-1D). In this paper, the optimization of two different device structure investigations is performed. In this proposed device structure, WS2 and IGZO are used as two ETL, CdS is used as a buffer layer, Sb2Se3 is used as an absorber layer, and PbS as HTL. Initially, the optimization of the device has been performed, followed by depth analysis of the doping densities. Resistance analysis is also performed to illustrate the effect of resistance on the device. Further, the impact of temperature on the device parameters is also represented, followed by a contour plot between thickness and bandgap for both devices. The impact of the series and shunt resistance on the performance of the solar cell is investigated. The effect of temperature is studied further, and it is observed that the solar device is temperature-sensitive. Finally, the optimized performance with IGZO ETL with PCE of 20.94% is achieved.

Full textAbstract:
This paper will explore the ways in which thrift operates as a signifier of a specific type of lprecarity and imperfection in young women’s lives in several popular series associated with the current ‘golden age’ of women’s television production. The twenty-something women of series including Girls, Insecure, Broad City, Fleabag, Can’t Cope Won’t Cope and Search Party, have all been raised in comfortable middle-class homes and are now living independently in major global, expensive cities. The precarity of the ways in which they dwell, at both a practical and figurative level, is a symptom of what has come to be understood as ‘adulting’—where relatively privileged millennials struggle with the rituals and realities of adult life in a starkly neoliberal society. Through a focus on the narrative device of the apartment plot, this paper will examine how the concept of thrift, with its central spectrum of necessity and choice, can illuminate both the everyday practices and the overarching logic of the adulting phenomenon as represented in this wave of television production. By attending to a variety of contemporary series by, for and about women, it will also argue for the ways in which both thrift and adulting can be understood as specifically gendered behaviours.

Full textAbstract:
Background Atrial fibrillation (AF) is the most common arrhythmia, and its prevalence is increasing. Early diagnosis is important to reduce the risk of stroke. Mobile health (mHealth) devices, such as single-lead electrocardiogram (ECG) devices, have been introduced to the worldwide consumer market over the past decade. Recent studies have assessed the usability of these devices for detection of AF, but it remains unclear if the use of mHealth devices leads to a higher AF detection rate. Objective The goal of the research was to conduct a systematic review of the diagnostic detection rate of AF by mHealth devices compared with traditional outpatient follow-up. Study participants were aged 16 years or older and had an increased risk for an arrhythmia and an indication for ECG follow-up—for instance, after catheter ablation or presentation to the emergency department with palpitations or (near) syncope. The intervention was the use of an mHealth device, defined as a novel device for the diagnosis of rhythm disturbances, either a handheld electronic device or a patch-like device worn on the patient’s chest. Control was standard (traditional) outpatient care, defined as follow-up via general practitioner or regular outpatient clinic visits with a standard 12-lead ECG or Holter monitoring. The main outcome measures were the odds ratio (OR) of AF detection rates. Methods Two reviewers screened the search results, extracted data, and performed a risk of bias assessment. A heterogeneity analysis was performed, forest plot made to summarize the results of the individual studies, and albatross plot made to allow the P values to be interpreted in the context of the study sample size. Results A total of 3384 articles were identified after a database search, and 14 studies with a 4617 study participants were selected. All studies but one showed a higher AF detection rate in the mHealth group compared with the control group (OR 1.00-35.71), with all RCTs showing statistically significant increases of AF detection (OR 1.54-19.16). Statistical heterogeneity between studies was considerable, with a Q of 34.1 and an I2 of 61.9, and therefore it was decided to not pool the results into a meta-analysis. Conclusions Although the results of 13 of 14 studies support the effectiveness of mHealth interventions compared with standard care, study results could not be pooled due to considerable clinical and statistical heterogeneity. However, smartphone-connectable ECG devices provide patients with the ability to document a rhythm disturbance more easily than with standard care, which may increase empowerment and engagement with regard to their illness. Clinicians must beware of overdiagnosis of AF, as it is not yet clear when an mHealth-detected episode of AF must be deemed significant.

AbstractAccess to safely managed drinking water (SMDW) remains a global challenge, and affects 2.2 billion people1,2. Solar-driven atmospheric water harvesting (AWH) devices with continuous cycling may accelerate progress by enabling decentralized extraction of water from air3–6, but low specific yields (SY) and low daytime relative humidity (RH) have raised questions about their performance (in litres of water output per day)7–11. However, to our knowledge, no analysis has mapped the global potential of AWH12 despite favourable conditions in tropical regions, where two-thirds of people without SMDW live2. Here we show that AWH could provide SMDW for a billion people. Our assessment—using Google Earth Engine13—introduces a hypothetical 1-metre-square device with a SY profile of 0.2 to 2.5 litres per kilowatt-hour (0.1 to 1.25 litres per kilowatt-hour for a 2-metre-square device) at 30% to 90% RH, respectively. Such a device could meet a target average daily drinking water requirement of 5 litres per day per person14. We plot the impact potential of existing devices and new sorbent classes, which suggests that these targets could be met with continued technological development, and well within thermodynamic limits. Indeed, these performance targets have been achieved experimentally in demonstrations of sorbent materials15–17. Our tools can inform design trade-offs for atmospheric water harvesting devices that maximize global impact, alongside ongoing efforts to meet Sustainable Development Goals (SDGs) with existing technologies.

This paper presents the design, development and testing of a novel neck chamber device for non-invasive stimulation of an individual carotid baroreceptor in a graded manner. The proposed neck chamber device is a strap-free design that avoids discomfort during testing due to tight seal generated by the neck collar design, and facilitates unilateral testing and targeted assessment without stimulating other neck baroreceptors. The device consists of two independent components to achieve these requirements: an outer suction mechanism and an inner chamber. The outer mechanism consists of multiple suction cups to grip the device over the human neck, while the inner chamber creates controlled positive and negative pressure for stimulation of baroreceptors using a pump. The indigenously developed device was employed for the testing by providing neck chamber stimulation in discrete steps of –20 mm Hg, –40 mm Hg, −60 mm Hg, 0 mm Hg, 20 mm Hg, 40 mm Hg and 60 mm Hg with the gap of 60 s between each stimulation as per the standard test protocol of autonomic function test. The changes in heart rate and RR interval were recorded to determine the baroreceptor gain using the logistic equation derivative and gain curve plot. The results of the present study show that the estimated baroreceptor gain is –0.109±0.04, which is consistent with the previous studies conducted using neck collar devices. The testing results showed that the desired objectives are achieved successfully by the prototype device, opening up the possibility of its use for the treatment of resistant hypertension.

Abstract This experiment was conducted in Thayer County, NE. The plot area was bordered on 1 side by winter wheat. Sorghum was planted perpendicular to the wheat. Plots were 4 rows (spaced 0.9 m), 30.5 m long arranged in a randomized complete block design with 4 replications. The 2 center rows were used for insect and plant stand counts. In-furrow planting-time application of granules was made by directing the insecticide delivery tube from Noble metering devices into the planter shoe just behind the seed delivery tube. Banded planting-time application of granules was made by directing the granule delivery tube from Noble metering devices to in front of the planter press wheel through a 18-cm bander. Seed treatment was made by thoroughly mixing the insecticide with seed in a paper sack just before planting. Postemergence application of granules were applied over the plants with a Noble metering device mounted on a 2-wheeled carriage, manually operated. Postemergence application of liquid insecticides was made on 24 Jun with a compressed air plot sprayer mounted on a high-clearance ground sprayer. Plants were 7.6-10 cm tall. Drop nozzles were used so that plants and surrounding soil were thoroughly covered. Spraying systems TX-12 nozzle tips were used.

It has been confirmed that rice fields contribute a lot to atmospheric methane. The object of this research was to analyse the diurnal changes of CH4 fluxes from a rice field in southern subtropical China in early rice season. The measuring device was a modification of a closed static chamber and gas chromatography. Samples of CH4 were collected from treatments with rice crop plot and bare soil plot at the same time. The results indicated that there are two peaks of variation in diurnal CH4 emissions during the growing season of rice. The average CH4 fluxes in the field appeared in the order of maturity stage (1.96 ± 0.33), booting stage (0.13 ± 0.01) and post-harvest stage (-0.01 ± 0.02) (mg·m-2·h-1). At booting stage, average flux of CH4 was much higher in the plot with rice plants than that of bare soil plot (p<0.01). Soil temperature had no significant effect on CH4 emissions at any stage in this study. The results showed that soil moisture and rice plants significantly affected CH4 flux in rice field.

Full textAbstract:
Objective: This study aimed to determine the intra-rater and inter-rater reliability and validity of a hybrid device, combining virtual reality goggles, a magnetometer and an inclinometer application for smartphones, to measure craniocervical range. Summary of Background Data: Accurate evaluation of craniocervical range of motion is important for early detection of certain diseased conditions and monitoring the progress of interventions. The universal goniometer is widely used for the measurement but it requires experienced practitioners. Whether a combination of virtual reality goggles and smartphone applications can provide the same or better performance compared with the goniometer is still unknown. Methods: Forty-one healthy adults from the department of physical medicine and rehabilitation were recruited for craniocervical range examination (flexion, extension, side-bending to the right or left and rotating to the right or left) by using the hybrid device and universal goniometer. Using the hybrid device, repeated measurements were performed twice by a primary rater and once by a second rater. The primary rater also conducted a measurement using the universal goniometer in the same cohort. The intra-rater and inter-rater reliability (intra-class correlation coefficient (ICC)) were calculated using the two-way random effect model, whereas the validity was examined by the Pearson correlation coefficient and Bland-and-Altman plot. The interval between the first and second sessions of the measurement for intra-rater reliability was set at 30 min. Results: Excellent intra-rater (ICC ≥ 0.925) and inter-rater (ICC ≥ 0.880) reliability was noted for the hybrid device. The minimal detectable changes from intra-observer and inter-observer comparisons ranged between 4.12° and 7.42° in all six directions. The Bland-and-Altman plot revealed small mean differences (≤1.68°) between the hybrid device and universal goniometer. Both instruments had highly correlated measurements of craniocervical motion (r values ≥ 0.918). Conclusion: For healthy participants, excellent intra-rater and inter-rater reliability was noted for the hybrid device, and the measurements were consistent with the universal goniometer measurements. Future studies are needed to examine whether the device can perform similarly for patients with neck disorders.

Full textAbstract:
Abstract. Accurate measurement of the amount and timing of surface runoff at multiple scales is needed to understand fundamental hydrological processes. At the plot scale (i.e., length scales on the order of 1–10 m) current methods for direct measurement of runoff either store the water in a collection vessel, which is not conducive to long-term monitoring studies, or utilize expensive installations such as large-scale tipping buckets or flume/weir systems. We developed an alternative low-cost, robust and reliable instrument to measure runoff that we call the "Upwelling Bernoulli Tube" (UBeTube). The UBeTube instrument is a pipe with a slot machined in its side that is installed vertically at the base of a runoff collection system. The flow rate through the slot is inferred by measuring the water height within the pipe. The geometry of the slot can be modified to suit the range of flow rates expected for a given site; we demonstrate a slot geometry that is capable of measuring flow rates across more than 3 orders of magnitude (up to 300 L min−1) while requiring only 30 cm of hydraulic head. System accuracy is dependent on both the geometry of the slot and the accuracy of the water level measurements. Using a pressure sensor with ±7 mm accuracy, the mean theoretical error for the demonstrated slot geometry was ~17% (ranging from errors of more than 50% at low flow rates to less than 2% at high flow rates), while the observed error during validation was 1–25%. A simple correction factor reduced this mean error to 0–14%, and further reductions in error could be achieved through the use of taller, narrower slot dimensions (which requires greater head gradients to drive flow) or through more accurate water level measurements. The UBeTube device has been successfully employed in a long-term rainfall-runoff study, demonstrating the ability of the instrument to measure surface runoff across a range of flows and conditions.

With an off-the-shelf pressure transducer sensor, the mean theoretical error for the demonstrated slot geometry was ~17% (ranging from errors of more than 50% at low flow rates to less than 2% at high flow rates), while the observed error during validation was 1–25%. A simple correction factor reduced this mean error to −14%, and further reductions in error could be achieved through the use of taller, narrower slot dimensions (which requires greater head gradients to drive flow) or through more accurate water level measurements. The UBeTube device has been successfully employed in a long-term rainfall-runoff study, demonstrating the ability of the instrument to measure surface runoff across a range of flows and conditions.

Accurately measuring tree diameter at breast height (DBH) and estimating tree positions in a sample plot are important in tree mensuration. The main aims of this paper include (1) developing a new, integrated device that can identify trees using the quick response (QR) code technique to record tree identifications, measure DBH, and estimate tree positions concurrently; (2) designing an innovative algorithm to measure DBH using only two angle sensors, which is simple and can reduce the impact of eccentric stems on DBH measures; and (3) designing an algorithm to estimate the position of the tree by combining ultra-wide band (UWB) technology and altitude sensors, which is based on the received signal strength indication (RSSI) algorithm and quadrilateral localization algorithm. This novel device was applied to measure ten 10 × 10 m square plots of diversified environments and various tree species to test its accuracy. Before measuring a plot, a coded sticker was fixed at a height of 1.3 m on each individual tree stem, and four UWB module anchors were set up at the four corners of the plot. All individual trees’ DBHs and positions within the plot were then measured. Tree DBH, measured using a tree caliper, and the values of tree positions, measured using tape, angle ruler, and inclinometer, were used as the respective reference values for comparison. Across the plots, the decode rate of QR codes was 100%, with an average response time less than two seconds. The DBH values had a bias of 1.89 mm (1.88% in relative terms) and a root mean square error (RMSE) of 5.38 mm (4.53% in relative terms). The tree positions were accurately estimated; the biases on the x-axis and the y-axis of the tree position were −8.55–14.88 cm and −12.07–24.49 cm, respectively, and the corresponding RMSEs were 12.94–33.96 cm and 17.78–28.43 cm. The average error between the estimated and reference distances was 30.06 cm, with a standard deviation of 13.53 cm. The device is cheap and friendly to use in addition to its high accuracy. Although further studies are needed, our method provides a great alternative to conventional tools for improving the efficiency and accuracy of tree mensuration.

The paper deals with the subject-plot motif “time extension” in the novel “The magic mountain” (“Der Zauberberg”) by Thomas Mann. The following constitutive features of this motif have been singled out: 1) the ability of the main character to concentrate on his inner world by means of a close introspection; 2) the usage of hermetic encapsulation device which consists in the limitation of the time and space conditions of the main hero’s life; 3) rethinking of values and life orientations forming new basic world-view concepts, such as life, death, disease, love. The application of the leitmotiv treated as recognizable main hero description and reiteration of other characters’ actions makes it possible to create the tonality of cantilena in the novel.

Annotation Purpose. Refinement of the mathematical description for calculating the movement of particles of sunflower material in the working gap of the threshing-separating device of the plot combine. Methods. Theoretical studies were carried out on the basis of the analysis of the dynamics of the movement of particles of sunflower material relative to the surface of a closed-type drum of a selection combine. Results. A mathematical description of the movement of particles of sunflower material in the working gap of the threshing-separating device of a selection combine with a closed drum is given. The dependence of the speed of movement of material particles on the initial speed of material feeding has been established. The dependence of the particle velocity on the radius of the closed-type drum of the selection combine has been established. The dependence of the speed of movement of the mass of sunflower material under the action of a closed-type drum of a selection combine on the coefficient of friction of the material is obtained. Conclusions. The obtained theoretical dependences of the speed of movement of the mass of sunflower material in the working gap of the threshing device of the selection harvester make it possible to substantiate the rational design and technological parameters of the closed-type threshing drum. Keywords: closed drum, speed, movement, coefficient of friction, plot combine, sunflower.

ObjectiveCurrent guidelines report no benefit for patent foramen ovale (PFO) closure compared to medical treatment in patients with cryptogenic ischemic stroke (IS) or TIA. Two recent randomized controlled clinical trials have challenged these recommendations.MethodsWe performed a systematic review and network meta-analysis of randomized controlled trials to estimate the safety and efficacy of closure compared to medical treatment, and to compare available devices. We conducted pairwise meta-analyses for closure vs medical therapy, irrespective of the device used, and for each device vs medical therapy.ResultsOur literature search highlighted 6 studies. PFO occlusion was associated with reduced risk of recurrent IS (risk ratio [RR] 0.42, 95% confidence interval [CI] 0.20–0.91) and IS/TIA (RR 0.65, 95% CI 0.48–0.88) but with increased risk of new-onset atrial fibrillation (AF) (RR 4.59, 95% CI 2.01–10.45) compared to medical treatment. In indirect analyses, both Amplatzer (AMP) and GORE devices were found to be associated with a lower risk of new-onset AF compared to STARFlex (SFX) (RR 0.25, 95% CI 0.10–0.65 and RR 0.28, 95% CI 0.08–0.95). Moreover, AMP was found to be associated with a lower risk of recurrent IS/TIA events compared to the SFX device (RR 0.35, 95% CI 0.14–0.91). In the clustered ranking plot on the risk of IS against new-onset AF, GORE was comparable to AMP; however, on the risk of IS/TIA against new-onset AF, AMP appeared to be superior to the GORE device. In both ranking plots, SFX was highlighted as the worst option.ConclusionPFO closure is associated with reduced risk of recurrent IS or IS/TIA and with increased risk of new-onset AF.

Full textAbstract:
The use of the deus ex machina in modern films is examined in this article. The deus ex machina is a device which is sometimes brought into play in a story as a last-resort effort to save the protagonist by an unexpected external force. Although the use of the device in ancient Greek drama has been rehabilitated, the same cannot be said about its modern use. Because the deus ex machina undermines the audience’s expectations for a story’s resolution, thus decreasing their emotional involvement, in screenwriting manuals, this device is often considered a cheap plot trick or a sign of bad writing. In this article, the functions that the device serves in ancient Greek drama are compared to some of its more successful uses in film narratives, demonstrating that it is a valuable tool which can effectively convey (among other things) a message of unity and hope.
