Scanning electron microscopes (SEM), which image sample surfaces by scanning with an electron beam, are widely used for steric observations of resting samples in basic and applied biology. Various conventional methods exist for SEM sample preparation. However, conventional SEM is not a good tool to observe living organisms because of the associated exposure to high vacuum pressure and electron beam radiation. Here we attempted SEM observations of live ticks. During 1.5×10−3 Pa vacuum pressure and electron beam irradiation with accelerated voltages (2-5 kV), many ticks remained alive and moved their legs. After 30-min observation, we removed the ticks from the SEM stage; they could walk actively under atmospheric pressure. When we tested 20 ticks (8 female adults and 12 nymphs), they survived for two days after SEM observation. These results indicate the resistance of ticks against SEM observation. Our second survival test showed that the electron beam, not vacuum conditions, results in tick death.
Vacuum venting is a method proposed to improve feature replication in microparts that are fabricated using micro-injection molding (MIM). A qualitative and quantitative study has been carried out to investigate the effect of vacuum venting on the nano/microfeature replication in MIM. Anodized aluminum oxide (AAO) containing nanofeatures and a bulk metallic glass (BMG) tool mold containing microfeatures were used as mold inserts. The effect of vacuum pressure at constant vacuum time, and of vacuum time at constant vacuum pressure on the replication of these features is investigated. It is found that vacuum venting qualitatively enhances the nanoscale feature definition as well as increases the area of feature replication. In the quantitative study, higher aspect ratio (AR) features can be replicated more effectively using vacuum venting. Increasing both vacuum pressure and vacuum time are found to improve the depth of replication, with the vacuum pressure having more influence. Feature ...

Hermetically sealed devices are usually vented and sealed at elevated temperatures. During the cooling period, the number of adsorption sites is large enough to provide a significant pressure reduction of air extraction, thus reducing the pressure by one or more orders of magnitude. Numerous examples show that when there is a large temperature change, there must be adsorption effect in the high real air. For example, when the heating element of the high vacuum furnace is still hot, isolate the vacuum guard from the pump and cut off the power supply. As long as the vacuum furnace is well sealed and the residual gas can be fully absorbed, the high vacuum of the vacuum furnace will be maintained overnight ...

February 22, 2013 - According to Millennium Research Group (MRG), the growing demographic at risk for breast cancer and increasing compliance with screening programs will spur demand for breast biopsies. Additionally, patients and clinicians are showing a growing preference for minimally invasive biopsies over open surgical alternatives. As a result, sales of breast biopsy devices used in these procedures will expand at a steady pace through 2017.. Within minimally invasive breast biopsies, clinicians are moving toward using more accurate methods, such as core needle biopsy (CNB) and vacuum-assisted biopsy (VAB), and away from fine-needle aspiration (FNA). VAB in particular is driving growth in this market because this is the most diagnostically accurate method of breast biopsy and VAB devices have higher selling prices. VAB devices will therefore continue to represent the largest and fastest-growing segment of the breast biopsy device market over the next five years, generating significant ...
Understanding the surface kinetics of precursor decomposition during thin film formation represents a key aspect in the understanding and engineering of chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes. The determination of activation energies of the surface reaction steps, however, is often challenging because it requires precise knowledge of precursor impinging rates. Afterward, the kinetics can be investigated by comparing the amount of deposited material with the absolute precursor flow. Ideally, the experimental equipment allows a distinction between gas phase and surface reactions. Both are difficult to achieve in conventional CVD processes. A high vacuum environment, however, enables the quantitative prediction of precursor impinging rates due to the ballistic nature of precursor transport; additionally precursor gas phase reactions do not occur. We investigated the surface reaction kinetics of titanium isopropoxide (TTIP) in the high vacuum CVD of titanium ...

The thermal fatigue behavior of the tantalum alloys T-111 (Ta-8W-2Hf) and ASTAR 811C (Ta-8W-1Re-0.7Hf-0.025C) has been evaluated using completely reversed push-pull fatigue tests conducted in ultrahigh vacuum with independently programmed temperature and strain cycles. Test results showed that cycling of the test temperature simultaneously with the mechanical strain in most cases significantly reduced the cycles to failure of both alloys compared to isothermal testing. Notched specimens had reduced lives under isothermal conditions, but the presence of a notch or use of a 1-h holdtime provided only a small further decrease in life for the temperature cycled tests. Compressive stress at the maximum temperature produced longer lives than tensile stress. ASTAR 811C was more fatigue resistant than T-111 isothermally and did not have as great a decrease in life with thermal cycling. Results are analyzed by partition of plastic strains into creep and creep-independent components and considering where ...

Milking Management III The Vacuum Pump Milking System 7 dead-ended lines flood more readily than looped milk lines. A looped line permits vacuum to be available from either end of the pipeline. Thus, high producing cows will not reduce vacuum from the milker unit upstream from that cow. No system should be installed without having a looped milk line. All milk lines should have at least 1 to 1.5 inches slope per 10 feet. Many milk lines were installed with sufficient slope, but, because people step on them, they have become level over time. Many barns do not have sufficient slope because in long barns the line would need to be very high at one end. The line also would be low at crosswalks. Vacuum Lines (From the Pump to the Trap) The most critical length of pipe is from the pump to the vacuum controller or controllers, where the highest volume of air is moved in the system. The vacuum controller admits air into the system, which is exhausted through the vacuum pump. If a 200 CFM pump is used, ...

A vacuum cleaner, also known as a sweeper or hoover, is a device that uses an air pump (a centrifugal fan in all but some of the very oldest models), to create a partial vacuum to suck up dust and dirt, usually from floors, and from other surfaces such as upholstery and draperies. The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models-small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both dust and liquids. Although vacuum cleaner and the short form vacuum are neutral names, in some countries (UK, Ireland) hoover is used instead as a genericized trademark, and as a ...

Vacuum ultraviolet fluorescence is observed from high density helium (up to three times liquid density) in microbubbles in implanted aluminum and tin. The fluorescence is excited by bombardment with low‐energy electrons (,5 keV). The resulting spectra are attributed to a combination of excimer (higher wavelength) and atomic (lower wavelength) fluorescences. The efficiency of the process is such that it has recently been proposed for the construction of a new solid state vacuum ultraviolet photon source.. ...

A getter is a deposit of reactive material that is placed inside a vacuum system, for the purpose of completing and maintaining the vacuum. When gas molecules strike the getter material, they combine with it chemically or by absorption. Thus the getter removes small amounts of gas from the evacuated space. The getter is usually a coating applied to a surface within the evacuated chamber. A vacuum is initially created by connecting a closed container to a vacuum pump. After achieving a vacuum, the container can be sealed, or the vacuum pump can be left running. Getters are especially important in sealed systems, such as vacuum tubes, including cathode ray tubes (CRTs), and vacuum insulated panels, which must maintain a vacuum for a long time. This is because the inner surfaces of the container release absorbed gases for a long time after the vacuum is established. The getter continually removes this residual gas as it is produced. Even in systems which are continually evacuated by a vacuum pump, ...

0068] FIGS. 9A-9E illustrate the use of biopsy device 10. FIG. 9A shows an exemplary sampling device in which inner component 60 includes multiple orifices (e.g., orifices 90a, 90b, 90c, 90d, 90e, and 90f). A pressure gradient can be formed in sampling portion 50 by applying a vacuum to orifices 90a, 90b, 90c, 90d, 90e, and 90f (as indicated by arrows 100). As shown in FIG. 9B the pressure gradient draws tissue 102 into sampling portion 50. As tissue 102 is drawn into sampling portion 50, portions of tissue 102 can come into physical contact with inner component 60. When tissue 102 comes into contact with inner component 60, tissue 102 can block one or more of the orifices (e.g., orifices 90a, 90b, 90c, 90d, 90e, and 900 which form the pressure gradient. As shown in FIG. 9B, tissue 102 has prolapsed such that orifices 90d and 90e are covered. When orifices 90d and 90e become covered, the pressure gradient applied by the other orifices (e.g., orifices 90a, 90b, 90c, and 900 increases helping to ...

TY - JOUR. T1 - The effect of vacuum mixing and pre-heating the femoral component on the mechanical properties of the cement mantle. AU - Baleani, M.. AU - Bialoblocka-Juszczyk, E.. AU - Engels, G. E.. AU - Viceconti, M.. PY - 2010/3. Y1 - 2010/3. N2 - We investigated the effect of pre-heating a femoral component on the porosity and strength of bone cement, with or without vacuum mixing used for total hip replacement. Cement mantles were moulded in a manner simulating clinical practice for cemented hip replacement. During polymerisation, the temperature was monitored. Specimens of cement extracted from the mantles underwent bending or fatigue tests, and were examined for porosity. Pre-heating the stem alone significantly increased the mean temperature values measured within the mantle (+14.2°C) (p ,0.001) and reduced the mean curing time (-1.5 min) (p ,0.001). The addition of vacuum mixing modulated the mean rise in the temperature of polymerisation to 11°C and reduced the mean duration of the ...
Carbon nanotube (CNT) is one of the most promising materials for a field emitter due to its remarkable electrical conductivity, chemical and mechanical stability, and characteristics having unique structures such as high aspect ratio [1-5]. Many researches have been highly devoted to developing a practical application for the commercialization of field emitter, but there are still some problems to be solved such as the lifetime of the emitter [6-10]. There are many factors that affect the emitter lifetime working in a state of vacuum. Among them, outgassing generated during emission is inarguably one of the most critical factors [11-13]. Especially, some organic binders can still remain after firing when the multi-walled carbon nanotube (MWCNT) emitter is made in paste and be the source to release gas in the vacuum panel. The outgassing can give a severe damage to the vacuum microelectronic device by electrical arcing and ion bombardment onto a cathode or an anode. In addition to the physical ...
A vacuum tube consists of two or more electrodes in a vacuum inside an airtight envelope. Most tubes have glass envelopes with a glass-to-metal seal based on kovar sealable borosilicate glasses, though ceramic and metal envelopes (atop insulating bases) have been used. The electrodes are attached to leads which pass through the envelope via an airtight seal. Most vacuum tubes have a limited lifetime, due to the filament or heater burning out or other failure modes, so they are made as replaceable units; the electrode leads connect to pins on the tubes base which plug into a tube socket. Tubes were a frequent cause of failure in electronic equipment, and consumers were expected to be able to replace tubes themselves. In addition to the base terminals, some tubes had an electrode terminating at a top cap. The principal reason for doing this was to avoid leakage resistance through the tube base, particularly for the high impedance grid input.[7][8] The bases were commonly made with phenolic ...

During joint replacement, surgical vacuum suction guarantees a sufficient overview on the situs. We assume high concentrations of mesenchymal stromal cells (MSCs) on surgical vacuum filters. We compared the in vitro proliferative and differentiation potency of cells from the following: (i) bone marrow (BM), (ii) cancellous bone (CB), (iii) vacuum filter (VF), and (iv) cell saver filtrate reservoir (SF) in 32 patients undergoing elective total hip replacement. Mononuclear cells (MNC) were isolated, and cell proliferation and colony-forming units (CFU) were measured. Adherent cells were characterized by flow cytometry for MSC surface markers. Cells were incubated with osteogenic, adipogenic, and chondrogenic stimuli. Cells were cytochemically stained and osteoblastic expression (RUNX-2, ALP, and BMP-2) investigated via qPCR. Dependent on the source, initial MNC amount as well as CFU number was significantly different whereas generation time did not vary significantly. CFU numbers from VF were superior to

With Thyratron power tubes and solenoids it is technically possible today.. William C. White, engineer of the vacuum tube research department of General Electric, makes that prediction. The field of vacuum tube engineering, he says, is not to simply do a thing in a different way and with different means, but to do it better and cheaper. It is possible, he adds, that as knowledge of the possibilities of vacuum tubes increases we may have to modify many of our ideas, such as the accepted one that an electric motor is the best and cheapest means of producing mechanical movement, at least in reciprocating parts..
