"Static form-finding of normal and defective catenaries based on the analytical exact solution of the tensile Euler–Bernoulli beam."

Abstract:

The aim of this research is to propose and develop an analytical exact solution for finding the static equilibrium configuration of a catenary before and after incurring defects such as tension loss or a broken dropper. The procedure includes considering the steady-state solution of the dynamic motion equation of the contact wire and the messenger cable. The wire and the cable are considered as tensile Euler–Bernoulli beams. The stiffness matrix of the beam is configured and is used to calculate the dropper's dead load. Progressively, a novel method is proposed to find the equilibrium configuration of the same catenary after the defect. The results prove that the tension loss in the messenger cable is more precarious than the tension loss in the contact wire. The broken dropper causes a significant sag in the sub-span and increases the static forces of the adjacent droppers. A comparison with field measurements justifies the accuracy of the results of the proposed model.

Abstract:

This paper presents a device to investigate dielectrophoresis (DEP) effects through different patterns of the electrodes. Pattern of electrodes, DEP time and voltage have been described to research the manipulation of particles by dielectrophoresis. The TiO2sample droplet was dropped onto several electrode pairs using a micro-dropper. We succeeded in manipulating TiO2particles along the electric field and deposited them across the gaps between two electrodes by modulating different factors. SEM images were used to confirm the patterns of different electrodes.

Abstract:

We consider a stochastic dynamic game with uncertainty about appearance of an dropper in infinite time horizon. For the lack of information about whether the dropper is present or not, two different states of nature can appear with some given probabilities at each stage. We study the non-cooperative behavior of players, and Nash equilibrium is considered as an equilibrium concept. We investigate how limited information about the dropper's appearance impacts the anti-jamming strategy.

Abstract:

Dropper is the key component of in a catenary system and it is prone to fatigue fracture. Dropper stress directly affects the operation safety of high-speed railway. In this paper, a span of dropper in a catenary system is modeled to investigate the effects of contact wire tension on dropper stress. The response equation of contact wire and the theoretical equation of dropper stress are deduced. The initial and boundary conditions of each dropper are determined, and then the stress of each dropper is calculated by the finite difference method using a MATLAB program. The results show that the stress amplitude and the maximum tensile stress of the dropper decrease significantly with the increase of contact wire tension. When the tension is low, the stress changes of dropper near the load location experience three stages: instant rebound, attenuated vibration, and bending compression. However, the attenuation vibration stage disappears when the tension is increased to a certain extent. Therefore, the control of the vibration response of the contact wire can effectively reduce the stress amplitude and the maximum tensile stress of the dropper, so as to improve the working reliability of the dropper.

Abstract:

Hydrodynamic effects of mussel farms have attracted increased research attentions in recent years. The understanding of the hydrodynamic impacts is essential for predicting the sustainability of mussel farms. A large mussel farm includes thousands of mussel droppers, and the combined drag on the mussel droppers is sufficient to possibly affect the longevity of the entire long-lines. This article intends to study the drag and wake of an individual long-line mussel dropper using computational fluid dynamics approaches. Two equivalent rough cylinders, namely, Curved-Model and Sharp-Model, have been utilized to simulate the mussel dropper, and each rough cylinder is assigned with surface roughness. The porosity is not considered in this article due to its complexity from inhalant and exhalant of mussels. Two-dimensional laminar simulations are conducted at Reynolds number from 10 to 200, and three-dimensional large eddy simulations are conducted at subcritical Reynolds number ranging from 3900 to [Formula: see text]. The results show that larger drag coefficients and Strouhal numbers are attributed to surface roughness and sharp crowns on the rough cylinder. The obtained drag coefficient ranges from 1.1 to 1.2 with respect to the diameter of the mussel dropper and the peak value of the tidal velocities. Wakes behind rough cylinders fluctuate more actively compared to those of smooth cylinders. This research work provides new insight for further investigations on hydrodynamic interactions between fluid and mussel droppers.

Full text

Abstract:

In this paper, the effects of load location on dropper stress are studied. We treat contact wire as a beam element and derive its response equation and then deduce the stress equation of dropper. A computer code based on MATLAB is written to calculate dropper stress using the finite difference method. The results show that there are three stages during the period of the stress changes of dropper, including instant rebound, damped sinusoidal vibration, and bending compression. The shorter the distance away from a load is, the larger the vertical displacement of the dropper is, which results in the corresponding increases of its stress amplitude and the maximum tensile stress. The load location has a significant impact on the stress changes of dropper. Compared to the condition of the load in the middle, the load acting on the edge of contact wire could induce the larger tensile stress when both ends of contact wire are considered as free boundaries. Therefore, it is necessary to add supports at both ends.

Abstract:

Elasticity variations in railway overhead contact line would lead to the fluctuation of contact force between pantograph and contact wire and produce a negative effect on the stability of current collection. Dropper distribution is one of the key factors affecting the elasticity of the contact wire. In this paper, the influence of dropper spacing on elasticity and quality of current collection have been studied using finite element analysis method by simulation. By analyzing the changes of elasticity value and contact force under different conditions of dropper distribution, the effect laws of dropper spacing on the contact wire elasticity and the quality of current collection under the speeds of 300km/h, 350km/h and 400km/h have been obtained.

In a Canadian shopping centre, a mitten or a box of condoms was accidentally dropped in front of 80 individual members of the public. The dropper was helped to retrieve his object by 43% of 30 people who saw the mitten but only by 17% of 30 people who saw the condoms. This replicates Edwards' 1975 report that the rate of helping was lower for an embarrassing than for a neutral object.

Abstract:

The rapid growth of marine aquaculture around the world accentuates issues of sustainability and environmental impacts of large-scale farming systems. One potential mitigation strategy is to relocate to more energetic offshore locations. However, research regarding the forces which waves and currents impose on aquaculture structures in such conditions is still scarce. The present study aimed at extending the knowledge related to live blue mussels (Mytilus edulis), cultivated on dropper lines, by unique, large-scale laboratory experiments in the Large Wave Flume of the Coastal Research Center in Hannover, Germany. Nine-months-old live dropper lines and a surrogate of 2.0 m length each are exposed to regular waves with wave heights between 0.2 and 1.0 m and periods between 1.5 and 8.0 s. Force time histories are recorded to investigate the inertia and drag characteristics of live mussel and surrogate dropper lines. The surrogate dropper line was developed from 3D scans of blue mussel dropper lines, using the surface descriptor Abbott–Firestone Curve as quality parameter. Pull-off tests of individual mussels are conducted that reveal maximum attachment strength ranges of 0.48 to 10.55 N for mussels that had medium 3.04 cm length, 1.60 cm height and 1.25 cm width. Mean drag coefficients of CD = 3.9 were found for live blue mussel lines and CD = 3.4 for the surrogate model, for conditions of Keulegan–Carpenter number (KC) 10 to 380, using regular wave tests.

Full text

Abstract:

The proportional loss rate differentiation (PLD) model was proposed to provide controllable and predictable loss rate for different classes of wired network connections. However, these algorithms cannot be directly applied to wireless networks, because of the location-dependent and time-varying wireless channel capacity. This paper proposes a novel packet dropper for fuzzy controlling of the proportional loss rate differentiation in a wireless network with multistate channel. The proposed dropper, fuzzy proportional loss rate dropper (FPLR), prefers to drop the small packets destined to a poor condition channel to improve the network performance. The loss rate debts of the poor channel will be compensated later to keep PLD. From simulation results, FPLR does achieve accurate loss rate proportion, lower queuing delay and loss rate, and higher throughput, compared with other methods in the wireless environment.

Abstract:

The article discusses the issues of increasing the efficiency of irrigation of crops cultivated in agriculture. Precise irrigation is an effective solution to irrigation problems. The methods and means of intellectual irrigation, based on sensors that monitor soil moisture and provide signals to the irrigation control solenoid valve, are described. A block diagram of an automatic drip irrigation system is described. For the experiment, five different types of droppers (A, B, C, D, and E) were used Rivulis Eurodrip brand, three of which are droppers with pressure compensation and two are the droppers without pressure compensation. Three parameters were used to study the characteristics of droppers: flow uniformity; volumetric water flow depending on the inlet pressure; determination of the dropper constant and the volume flow exponent. Droppers were tested at three pressures in the system: 0.05, 0.2 and 0.35 MPa. At each pressure value, the experiment was performed in triplicate. The process of calibrating humidity sensors is described. An analysis is made of the effect of soil moisture on the electrical resistance of the sensor for various types of soils. It is recommended that moisture sensors be calibrated to local soil and water conditions.

Abstract:

Eye burns due to the accidental application of pharmacological or nonpharmacological substances packaged in plastic dropper bottles have been described for more than three decades and continue to occur. These burns can cause potentially serious corneal injuries. We report the case of a patient who mistakenly applied salicylic acid to the right eye after confusing it with an eye lubricant, which caused him a severe corneal burn. Fortunately, after aggressive medical and surgical management (including oxygen therapy and amniotic membrane grafting), the visual results were good.We suggest conducting educational campaigns and taking legislative measures in our country to avoid packaging corrosive substances in this type of dropper bottle to reduce the risk of accidental burns.

Abstract:

Objective: to confirm a therapeutic equivalence and similar safety profile of “Midazolam, oromucosal (buccal) solution” and “Sibazon, solution for intravenous and intramuscular administration” used in children aged from 1 year to 18 years suffering from primary generalized and bilateral tonic, clonic and tonic-clonic seizures.Material and methods. An open-label, randomized clinical trial on efficacy and safety was conducted with 25 patients having primary generalized and bilateral tonic, clonic and tonic-clonic seizures due to epilepsy or epileptic syndrome. The study used age-appropriate doses of Midazolam with a single buccal administration as well as diazepam (Sibazon) for single intramuscular administration. Midazolam dosing was as follows: 5 mg for children of the younger age group (1 tube-dropper 5 mg/ml), 7.5 mg for children of the middle age group (1 tube-dropper 5 mg/ml and 1 tube-dropper 2.5 mg/ml), 10 mg for older children (2 tube-droppers 5 mg/ml). The drug effectiveness was assessed by primary and secondary criteria. The number of cases of drug administration in each group was used as the primary criteria, in which the convulsions ended up within 10 minutes after using the drug and did not resume within 60 minutes after drug administration. The following criteria were used as secondary: no repeated convulsive seizures within 24 hours after drug administration, no repeated convulsive seizure within 48 hours after drug administration, time before repeated convulsive seizure within 48 hours after drug administration. Clinical assessment was carried out according to clinical data, electroneurophysiologic (electroencephalographic) studies, electrocardiography, clinical blood and urine tests, aswell as biochemical blood tests by measuring glucose, total protein, albumin, total bilirubin, cholesterol, aspartate aminotransferase, alanine aminotransferase, creatine phosphokinase, alkaline phosphatase, creatinine, urea, and creatinine clearance level.Results. Compliance with the first efficacy criterion after using Midazolam and Sibazon was observed in 11 (84.6%) and 9 (75%) patients in Group 1 and Group 2, respectively, showing insignificant differences (Fisher's exact test (FET): p=0.645). The number of no cases of repeated convulsive seizure within 24 hours after drug administration differed significantly and was 12 (92.3%) and 6 (50%), respectively (FET: p=0.030). The number of cases with no second seizures within 48 hours after drug administration in Group 1 and Group 2 was 12 (92.3%) and 5 (41.7%), respectively, showing insignificant differences (FET: p=0.0112). No serious adverse events were reported during the study. No patients cancelled participation in the study due to developed adverse event.Conclusion. The data obtained evidence about compatibility of therapeutic efficacy profile and similar safety profile for “Midazolam, oromucosal (buccal) solution” and “Sibazon, solution for intravenous and intramuscular administration” that agrees with multiple data of earlier studies.

Abstract:

The results of laboratory studies of the proposed drip irrigation system are given. Five different types of droppers have been investigated to quantify the hydraulic characteristics. The dependences of the uniformity of water flow through droppers with a change in the working pressure in the system are obtained. Laboratory studies of the experimental facility were carried out at the training and demonstration center of Kazan State Agrarian University. The experimental installation consists of a storage tank, a submersible pump, five P.V.C. main pipes with a length of 3 m and a diameter of 16 mm, stop valves of a drip line, pressure gauges, a main stop valve, a collector line, a return line, and droppers. Before starting the experiments, air was removed from the system and pressure at the inlet to each main pipe was adjusted to the required value. Immediately under each drip, 500 ml volumetric containers were placed to determine the volume of leaked water in two minutes. Significant uniformity of water consumption and the smallest deviations from the specified nominal flow rate were achieved with type A and C droppers (with pressure compensation) at an operating pressure of 0.2 MPa; with type B droppers (also with pressure compensation), water flow uniformity decreased with increasing pressure. The results of the research show that pressure-compensated droppers are less sensitive to pressure changes with an operating pressure of 0.35 MPa. Water consumption (q) for type A droppers increased by 5.27%, B - by 27.3% and C - by 9.1%. Dropper type D and E have the lowest uniformity of water flow at different pressure levels. Under actual irrigation conditions, it is recommended to install pressure gauges not only in the collector line, but also on the main pipes (preferably at the end of each main pipe) to determine the differential and pressure losses in the system.

Abstract:

A common problem for healthcare providers is accurately tracking patients’ adherence to medication and providing real-time feedback on the management of their medication regimen. This is a particular problem for eye drop medications, as the current commercially available monitors focus on measuring adherence to pills, and not to eye drops. This work presents an intelligent bottle sleeve that slides onto a prescription eye drop medication bottle. The intelligent sleeve is capable of detecting eye drop use, measuring fluid level, and sending use information to a healthcare team to facilitate intervention. The electronics embedded into the sleeve measure fluid level, dropper orientation, the state of the dropper top (on/off), and rates of angular motion during an application. The sleeve was tested with ten patients (age ≥65) and successfully identified and timestamped 94% of use events. On-board processing enabled event detection and the measurement of fluid levels at a 0.4 mL resolution. These data were communicated to the healthcare team using Bluetooth and Wi-Fi in real-time, enabling rapid feedback to the subject. The healthcare team can therefore monitor a log of medication use behavior to make informed decisions on treatment or support for the patient.

Abstract:

Abstract. Lord Kelvin (William Thomson) made important contributions to the study of atmospheric electricity during a brief but productive period from 1859–1861. By 1859 Kelvin had recognised the need for "incessant recording" of atmospheric electrical parameters, and responded by inventing both the water dropper equaliser for measuring the atmospheric potential gradient (PG), and photographic data logging. The water dropper equaliser was widely adopted internationally and is still in use today. Following theoretical considerations of electric field distortion by local topography, Kelvin developed a portable electrometer, using it to investigate the PG on the Scottish island of Arran. During these environmental measurements, Kelvin may have unwittingly detected atmospheric PG changes during solar activity in August/September 1859 associated with the "Carrington event", which is interesting in the context of his later statements that solar magnetic influence on the Earth was impossible. Kelvin's atmospheric electricity work presents an early representative study in quantitative environmental physics, through the application of mathematical principles to an environmental problem, the design and construction of bespoke instrumentation for real world measurements and recognising the limitations of the original theoretical view revealed by experimental work.

Abstract:

Sabatieria is the most abundant nematode genus on the Campos Basin continental slope. Two new species are described here. Sabatieria exilis sp. n. has a small rounded head and a narrow pharynx with a cuticularized anterior end. Sabatieria fidelis sp. n. has a short outstretched testis, spicules directed ventrally and shaped like the tip of a dropper, the gubernaculum with a v-shaped cuticularized area in the distal part, short cephalic and somatic setae, and a longer tail.

Abstract:

Lack of adherence with vitamin D supplementation is still a risk factor for rickets. In a randomized cross-over design, infants received 400 IU cholecalciferol by dropper (1 mL syrup) or filmstrip. Infant and parent preference scores and adherence were then compared. Forty-three parents of healthy infants preferred the filmstrip (85.4% of parents; 95% confidence interval of 70.1%–93.9%; p < 0.001), a result that was corroborated by higher infant and parental scores and compliance. Ease of administration of supplements with improved acceptance may improve adherence.

Abstract:

Objective: Conduct effective sensory method on three nail strengtheners with different packaging and pharmaceutical forms commercialised in Brazil. Methods: Two affective tests, of acceptance and sorting-preference, and a purchase intention test were conducted. The attributes packing appearance, ease of application provided by the packaging and texture and spreadability of the pharmaceutical form were evaluated, using the hedonic scale of 9 points to evaluate the attributes and 5 points to assess the intention of buying. The sensory panel was composed of 32 judges, consumers or potential consumers. Results: On the acceptance test, the pen with emulsion pharmaceutical form obtained was most preferred on the appearance of the package (7.88) and ease of application (7.72) attributes. The sample most preferred on texture and spreadability attribute was the nail polish bottle with brush containing enamel base pharmaceutical form (8.06), followed by pen bottle containing emulsion (6.75) and dropper bottle containing oil as pharmaceutical form (5.41) respectively, with statistical significance (p<0.05). All samples were higher with significant difference (p<0.05) compared with the dropper bottle containing oil on purchase intent.Conclusion: It was demonstrated that pen bottle had the highest preference on package appearance and ease of application attributes and the enamel base pharmaceutical form had the highest preference in the texture and spreadability attribute. The nail polish bottle containing the pharmaceutical form enamel base showed the highest preference in purchase intention and sorting-preference test.

Abstract:

Previous research has optimized the colchicine dropper technique for chromosome doubling under greenhouse conditions. In recent years, in vitro germination of cut strawberry achenes has greatly increased germination rates. Combining the two techniques would be especially useful when chromosome doubling is desired for interspecific hybridization. Fragaria vesca was chosen for initial study. Treatments included colchicine levels of 0%, 1%, 2%, 3%, 4%, or 5% (w/v); exposure time to colchicine was from 6 to 16 to 26 hours; application was at the cotyledon stage or after the first true leaf formed; presence or absence of 3 g activated charcoal/liter; and presence or absence of DMSO. Media consisted of MS salts and vitamins, 30 g sucrose/liter, and 2.5 g phytogel/liter. Charcoal enhanced upward growth of seedlings, thus allowing better placement of colchicine droplets. Reduced exposure time and application at the first true-leaf stage allowed higher levels of colchicine to be used without greatly reducing the vigor of treated seedlings.

Abstract:

This paper presents two boiling experiments that can be integrated in the undergraduate heat transfer laboratory. The objective of these experiments is to enhance the understanding of the boiling process by undergraduate mechanical engineering students. These experiments expose students to several important concepts in boiling, such as subcooled boiling, modes of pool boiling, and the Leidenfrost phenomenon. The experimental set-up required to carry out these experiments is simple. It includes metallic plates such as brass, stainless steel or aluminium, a heating source such as a heating pad, thermocouples, a stopwatch, a liquid dropper, and a camera. The equipment is inexpensive and available in almost all undergraduate heat transfer laboratories.
