Розглянуто практичні апаратні рішення щодо виділення пульсацій тиску в манжеті, що дозволяють підвищити точність та захищеність від перешкод алгоритмів вимірювання тиску. Досліджено вплив АЧХ фільтрів виділення слабких пульсацій тиску в манжеті на форму вихідного сигналу в неінвазивних автоматичних вимірювачах артеріального тиску. Під час розробки каналу неінвазивного вимірювання тиску для приліжкового монітору виявлено невідповідність між формою кривих пульсацій тиску в манжеті, отриманих прямою високоточною реєстрацією абсолютного тиску, з формою відповідних осциляцій. Виконано моделювання в MicroCap-12 схеми каскаду виділення пульсацій тиску, яке підтвердило, що форма і амплітудні характеристики вихідного сигналу залежить від ЧСС. Висновки: проектування каналу виділення пульсацій тиску в манжеті рекомендується виконувати у вигляді смугового фільтру, формулюючи вимоги щодо нього у часовій області (до гладкості імпульсної перехідної функції), як більш значущі у даному разі, ніж частотні. Ключові слова: артеріальний тиск, осцилометричний метод, пульсації тиску, схемотехніка неінвазивного каналу

This paper describes the experimental results of testing a prototype of a high precision human skin rapid temperature fluctuations measuring instrument. Based on the author’s work, an original circuit solution on a miniature semiconductor diode sensor has been designed. The proposed circuitry provides operation in the full voltage range with automatic setting and holding the operating point, as well as the necessary slope of the conversion coefficient (up to 2300 mV/°C), which makes it possible to register fast temperature oscillations from the surface of the human body and other biological objects. Simulation results in the Microcap 12 software and laboratory tests have confirmed all declared design specifications: temperature resolution of 0.01 °C, transducer thermal time constant of 0.05 s. An original thermostat and an experimental setup for the simultaneous registration of the electrocardiogram, pulse wave signals from the Biopac polygraph MP36 and a signal of temperature oscillations from the prototype thermometer have been designed for further investigations. The preliminary test results indicates that using the designed measuring instrument gives a possibility to provide an in-depth study of the relationship between micro- and macro-blood circulations manifested in skin temperature fluctuations.

ABSTRACTA novel phenotype was recently identified in which specific strains ofEscherichia coliinhibit competingE. colistrains via a mechanism that was designated “proximity-dependent inhibition” (PDI). PDI-expressing (PDI+)E. coliis known to inhibit susceptible (PDI−)E. colistrains, including several enterohemorrhagic (EHEC) and enterotoxigenic (ETEC)E. colistrains. In this study, every strain from a genetically diverse panel ofE. coliO157:H7 (n= 25) and additional strains ofE. coliserovar O26 were susceptible to the PDI phenotype. LIVE/DEAD staining was consistent with inhibition by killing of susceptible cells. Comparative genome analysis identified the genetic component of PDI, which is composed of a plasmid-borne (Incl1) operon encoding a putative microcin and associated genes for transport, immunity, and microcin activation. Transfer of the plasmid to a PDI−strain resulted in transfer of the phenotype, and deletion of the genes within the operon resulted in loss of the inhibition phenotype. Deletion of chromosomally encodedtolCalso resulted in loss of the inhibitory phenotype, and this confirmed that the putative microcin is most likely secreted via a type I secretion pathway. Deletion of an unrelated plasmid gene did not affect the PDI phenotype. Quantitative reverse transcription (RT)-PCR demonstrated that microcin expression is correlated with logarithmic-phase growth. The ability to inhibit a diversity ofE. colistrains indicates that this microcin may influence gut community composition and could be useful for control of important enteric pathogens.

ABSTRACT Many Escherichia coli K-12 strains display an intrinsic resistance to the peptide antibiotic microcin J25. In this study, we present results showing that the leucine-responsive regulatory protein, Lrp, is involved in this phenotype by acting as a positive regulator of YojI, a chromosomally encoded efflux pump which expels microcin out of cells. Exogenous leucine antagonizes the effect of Lrp, leading to a diminished expression of the pump and an increased susceptibility to microcin J25.

Purpose – The purpose of this study was to investigate the performance of a single-bridge ZnO nanorod as a photodetector. Design/methodology/approach – The fabrication of the design sensor with ∼6-μm gap Schottky contacts and bridging of the ZnO nanorod were based on conventional photolithography and wet-etching technique. Prior to bridging, the ZnO nanorods were grown by the hydrothermal process. The 0.35 M seed solution was prepared by dissolving zinc acetate dihydrate in 2-methoxyethanol, and monoethanolamine, which acts as a stabilizer, was added drop-wise. Before starting the solution deposition, and oxide, titanium (Ti) and gold (Au) layer deposition, p-type (100) silicon substrate was cleaned with Radio Corporation of America (RCA1) and RCA2, followed by dipping in diluted hydrofluoric acid. The aged solution was dropped onto the surface of the Au microgap structure, using a spin coater at a spinning speed of 3,000 rpm for 45 seconds, and then dried at 300°C for 15 minutes, followed by annealing at 400°C for 1 hour. The hydrothermal growth was carried out in an aqueous solution of zinc nitrate hexahydrate (0.025 M) and hexamethyltetramine (0.025 M). Findings – In this study, ZnO nanorods were grown on a SiO2 substrate by the hydrothermal method. Microgap electrodes with ∼6-μm spacing were achieved by using the wet-etching process. After the growth process, an area-selective mask was utilized to reduce the number of rods between the nearby gap areas. The obtained single ZnO nanorod was tested for the UV-sensing application. The single ZnO nanorod photodetector exhibited a UV photoresponse, thereby indicating potential as a cost-effective UV detector. The response and recovery times of the fabricated device were 65 and 95 seconds, respectively. Structural analysis was captured using X-ray Diffraction (XRD), whereas surface morphology was determined using scanning electron microscopy. Originality/value – This paper demonstrates the effect of UV photon on a single-bridge ZnO nanorod between microgap electrodes.

SummaryA 1.6 kg, six-week-old Tibetan Terrier was admitted with a 12-hours history of acute onset of progressive tetraparesis following insertion of a microchip to the dorsal cervical region. Neurological examination indicated a lesion to the Ce1 to Ce5 spinal cord segments. Radiographic examination confirmed the intra-spinal location of a microchip foreign body at the level of the second cervical vertebra. Microchip removal was achieved following dorsal hemi-laminectomy; significant intra-operative haemorrhage was encountered. The puppy was ambulatory at day seven. Follow-up telephone interview 18 months postoperatively confirmed that the patient had made a good recovery although it had a mild residual right- sided torticollis.

The distribution and abundance of three Camelina species introduced to Canada is unknown, but critical for evaluating the risks associated with unconfined release of transgenic Camelina sativa (L.) Crantz (2n = 40). Furthermore, previous reports suggest Canadian populations of Camelina microcarpa Andrz. ex DC. vary for ploidy and ability to hybridize with C. sativa. We completed 8 weeks of field work in Alberta, Saskatchewan, Manitoba, southern Ontario, Quebec, and the Maritimes. We determined the ploidy composition of the populations found. We did not locate Camelina alyssum (Mill.) Thell., but located four sites with C. sativa and 34 with C. microcarpa. Eleven C. microcarpa populations were tetraploid (2n = 26, 1.00pg/2C) and 22 were hexaploid (2n = 40, 1.50pg/2C), while two populations were mixed. We examined material from botanical gardens and plant gene resource centres assessing total nuclear DNA content and completing chromosome counts for each species and cytotype identified, to determine whether tetraploid and hexaploid C. microcarpa were included in these collections. No tetraploid material was included in the C. microcarpa accessions received; however, a diploid (2n = 12, 0.54pg/2C) was found. Given the current geographic ranges, abundance, and chromosome counts of these species, the greatest risk of hybridization with transgenic C. sativa is from hexaploid C. microcarpa.

SummaryA three-year-old female, entire Yorkshire Terrier dog was examined because it had progressive non-weight-bearing left forelimb lameness and tetraparesis of two weeks duration. Clinical signs were first observed following mating. Examination confirmed non-weight-bearing left forelimb lameness and tetraparesis. Left forelimb muscle atrophy was also noticed. Survey radiography revealed a metallic foreign body consistent with a microchip in close proximity to the left articular facets between the fifth and sixth cervical vertebrae. Computed tomography identified the exact location of the foreign body encroaching on the left dorsolateral vertebral canal, and osteolysis of the lamina of the sixth cervical vertebra. Surgical removal of the foreign body was performed via a dorsal approach to the caudal cervical vertebral column. Two weeks following surgery the dog showed return of left forelimb function and resolving tetraparesis. Microchip implantation had been performed three years previously.

Purpose This paper aims to report the first iteration on the Light Detection and Ranging (LIDAR) Engineering Model altimeter named HELENA. HELENA is a Time of Flight (TOF) altimeter that provides time-tagged distances and velocity measurements. The LIDAR can be used for support near asteroid navigation and provides scientific information. The HELENA design comprises two types of technologies: a microchip laser and low noise sensor. The synergies between these two technologies enable developing a compact instrument for range measurements of up to 14 km. Thermal-mechanical and radiometric simulations of the HELENA telescope are reported in this paper. The design is subjected to vibrational, static and thermal conditions, and it was possible to conclude by the results that the telescope is compliant with the random vibration levels, the static load and the operating temperatures. Design/methodology/approach The Asteroid Impact & Deflection Assessment (AIDA) is a collaboration between the NASA DART mission and ESA Hera mission. The aim scope is to study the asteroid deflection through a kinetic collision. DART spacecraft will collide with Didymos-B, while ground stations monitor the orbit change. HERA spacecraft will study the post-impact scenario. The HERA spacecraft is composed by a main spacecraft and two small CubeSats. HERA will monitor the asteroid through cameras, radar, satellite-to-satellite doppler tracking, LIDAR, seismometry and gravimetry. Findings The HELENA design comprises two types of technologies: a microchip laser and low noise sensor. The synergies between these two technologies enable developing a compact instrument for range measurements of up to 14 km.

This paper presents a model predictive control (MPC) framework to minimize the energy cost associated with the building heating, ventilation, and air-conditioning (HVAC) system integrated with a micro-scale concentrated solar power (MicroCSP) system. To this end, a MicroCSP model is developed and then integrated to the building model of an office building in Michigan Technological University. Then, an MPC framework is designed to optimize MicroCSP electrical and thermal energy flows for HVAC use in the building. The optimal control results show that the designed MPC framework reduces the HVAC energy cost by 37–42% for a sample sunny day by optimally utilizing the solar energy, compared to the HVAC system without MicroCSP with an MPC controller. The cost saving varies from 12% to 47% depending on seasonal weather variations.

Abstract In this case study, EP Petroecuador and Consorcio Shushufindi evaluate a chemical treatment and completion strategies to reduce the extensive impact of bottomhole scale deposits on oil production, electrical submersible pumps (ESP) run life, and operating costs of wells completed in the high-scaling tendencies reservoir. The positive impact on oil production optimization resulting from these strategies will also be discussed and the advantages, lessons learned, and constraints of this work. Conventionally, corrosion and scale chemical inhibitors are deployed through capillary lines; this method is effective up to the pump depth but does not prevent deposits at the perforations or at the lower completion and near wellbore. Rapid production decline or complete loss of production is observed, requiring costly well interventions. Laboratory analysis and evidences from the interventions show that lower T-sand fluids present a high-scale tendency at the bottomhole; therefore, a process to identify candidates and deploy chemical treatment in the rathole to prevent scale deposits was defined and proved. The technology selected was encapsulated scale inhibitors (microcaps). Based on the process, two wells were selected from a portfolio of 12 wells that match the criteria to apply the method to deploy the technology. The following observations were drawn: -Calcium carbonate (CaCO3) is the most common scale-ESP parameters and production surveillance are essential for early detection of problems associated with scale deposits at bottomhole-The action of microcaps and the installation of a pipe tail below the ESP base sensor allowed to deepen the continuous dosage of scale inhibitor and has already doubled the run life of the ESP equipment, with direct savings on operations costs (approximately USD 240,000) in the short time and continue and can continue to yield more.-According to post workover (WO) production tests of the two candidates and the performance of ESP parameters, the application of this strategy made possible to restore the productivity indexes and sustain them over time. This leads to reduction in production losses of 310 BOPD or 60% of the actual production in the similar period before the treatment.-The microcaps can be applied and refilled through rig-less annulus-It is a low-cost solution for scale problems at bottomhole. This document presents an analysis to reduce operating costs in wells that produce fluids with a high-scaling tendency at bottom hole, through an unconventional and low-cost strategy of chemical treatment from the sand face to the wellhead. This novel process and microcaps application can be used in wells in remote and difficult areas to service on a regular basis.

Data collection from full-scale 12-meter yachts was an important part of the project that led to the America's Cup challenger Stars & Stripes. A data system was developed around Ockam on-board instruments with a telemetry link to two DEC Microvax II computers, one aboard the tender and one on shore. Applications of the data obtained include validation and improvement of computer models and towing tank tests used in design; discrimination of performance differences associated with hull, keel and sail changes; and development of on-board computer systems to assist decision-making during races.

A micro gas turbine impeller is a highly challenging component to fabricate given the stringent tolerance requirements. This paper highlights and reports a novel process to machine and fabricate a SS 304 impeller using a 3 axis cnc milling machine with minimum usage of job overhead. The impeller chosen to demonstrate this process is a 12 vaned impeller with outside diameter of 110 mm with an elliptical hub surface and constant radius circular shroud surface. The blade thickness varies from 1.6 mm at tip and 3.5 mm at hub. The intersection region of the blade with the disk has a uniform fillet radius of 1.5 mm. The blade exit height is 16 mm. Blades are not perpendicular to the hub surface, intersecting angle is changing as you move down the blades. The height of the blade varies from exducer to inducer is 4.5 times. It is seen that a considerable saving in time and effort without a compromise on the dimensional tolerances is obtained with the above procedure.

Magnetic nanoparticle hyperthermia has attracted growing attentions recently due to its ability of confining nanoparticle-induced heating in targeted tumor region. Our recent studies have identified an injection strategy to achieve repeatable and controllable nanoparticle deposition patterns in PC3 tumors using microCT scans. Based on the injection strategy, simulation of temperature elevations in tumors is conducted to design heating protocols to induce irreversible thermal damage to the entire tumors. In this study, in vivo heating experiments are performed on PC3 tumors implanted on mice following the designed heating protocols. The tumors in the control group without heating triple their sizes over a period of eight weeks. The tumors in the heating groups are heated for either 25 minutes or 12 minutes, representing that the Arrhenius integral is equal to or larger than 4 or 1 in the entire tumors, respectively. The tumors in the heating group of 25 minutes disappear completely after the 3rd days, and the site maintains the disappearance for over eight weeks. The sizes of the tumors in the heating group of 12 minutes decrease in the first ten days, however, the tumors re-grow afterwards, and by the end of the 8th week, they are approximately 60% larger than their initial size. This study demonstrates the importance of imaging-based design for individualized treatment planning. The success of the designed heating protocol in complete damaging PC3 tumors validates the theoretical models used in planning the heating treatment in magnetic nanoparticle hyperthermia.

This paper presents the effect of temperature distributions in different heaters and channels on DNA amplification for polymerase chain reaction biochip. We utilized the Micro-Electro-Mechanical System to complete biochip accuracy. The TPX (Poly-4-methyl-pentene-1) was used as the polymer material. The microchip composed of two parts. One is the heater and temperature sensor on a top cover, the other is the microchannel and reaction chamber on a bottom substrate. Then we designed two kinds of chip materials: 1. a glass cover and a TPX substrate, 2. a TPX cover and a TPX substrate. Temperature is the most important in PCR, so the more uniform one is better. And we designed two kinds of heater. According to heat conduction simulation, we can find the best heater pattern. The simulation result is that the design of long inside distance and short outside distance between heater columns was the best one. The reagent of 10 μL was repeated twenty-five cycles to complete PCR process. The temperature controller could reach the speed of heating 20° C /sec and the speed of cooling 5°C /sec. Thus the PCR process could be achieved for twenty-five cycles within 35 minutes. Finally we used the instruments to check DNA amplification result qualitatively and quantitatively. The DNA amplification length was 108 bps. The DNA amplification of long inside distance and short outside distance between heater columns was 90.17 ng/μL, and was larger 12 ng/μL than that of equally distances. Excellent correlation between simulation analysis and experimental result was obtained in this study.
