Back to basics: making a vacuum-formed, custom-fitted intraoral mouthguard using the "dry model" technique. (1/240)

For a mouthguard to function properly, it must fit well. It is possible to produce a well-fitting mouthguard using the "dry model" technique, which is relatively inexpensive and easy to learn. Custom-fitted intraoral mouthguards help prevent or reduce the severity of concussions as well as minimize oral cavity injuries. (+info)

Safety evaluation of sous vide-processed products with respect to nonproteolytic Clostridium botulinum by use of challenge studies and predictive microbiological models. (2/240)

Sixteen different types of sous vide-processed products were evaluated for safety with respect to nonproteolytic group II Clostridium botulinum by using challenge tests with low (2. 0-log-CFU/kg) and high (5.3-log-CFU/kg) inocula and two currently available predictive microbiological models, Food MicroModel (FMM) and Pathogen Modeling Program (PMP). After thermal processing, the products were stored at 4 and 8 degrees C and examined for the presence of botulinal spores and neurotoxin on the sell-by date and 7 days after the sell-by date. Most of the thermal processes were found to be inadequate for eliminating spores, even in low-inoculum samples. Only 2 of the 16 products were found to be negative for botulinal spores and neurotoxin at both sampling times. Two products at the high inoculum level showed toxigenesis during storage at 8 degrees C, one of them at the sell-by date. The predictions generated by both the FMM thermal death model and the FMM and PMP growth models were found to be inconsistent with the observed results in a majority of the challenges. The inaccurate predictions were caused by the limited number and range of the controlling factors in the models. Based on this study, it was concluded that the safety of sous vide products needs to be carefully evaluated product by product. Time-temperature combinations used in thermal treatments should be reevaluated to increase the efficiency of processing, and the use of additional antibotulinal hurdles, such as biopreservatives, should be assessed.

Trained sensory panel and consumer evaluation of the effects of gamma irradiation on palatability of vacuum-packaged frozen ground beef patties. (3/240)

The objectives for this experiment were to determine the effects of gamma irradiation on 1) the palatability of vacuum-packaged frozen ground beef patties by trained sensory panel and 2) consumer evaluation of the taste of hamburgers made with those patties. Boxes (4.5 kg) of frozen (-28 degrees C) ground beef patties (113.4 g/patty, 19% fat) from a commercial supplier were irradiated at a commercial gamma irradiation facility at one of three levels (0, 3.0, or 4.5 kGy). All boxes were stored at 28 degrees C for 27 to 29 d after irradiation before evaluation by a trained descriptive attribute sensory panel and for 62 to 104 d after irradiation before consumer evaluation. The trained panel evaluated grilled patties for ground beef aroma intensity, off-aroma, and off-flavor on 4-point scales (4 = intense, none, and none; 1 = none, intense, and intense, respectively) and ground beef flavor intensity, tenderness, and juiciness on 8-point scales (8 = extremely intense, tender, or juicy; 1 = extremely bland, tough, or dry). Control patties had more intense (P<.05) ground beef aroma (3.1 vs 2.6), less off-aroma (3.3 vs 2.6), and more intense ground beef flavor (4.9 vs. 4.3) than irradiated patties. However, there were no differences (P>.05) in any sensory trait between frozen ground beef patties treated with 3.0 or 4.5 kGy of gamma irradiation. There were no differences (P>.05) among treatments for tenderness (6.3, 6.6, and 6.7) or juiciness ratings (5.7, 5.9, and 5.9), respectively, for 0, 3.0, and 4.5 kGy. The consumers evaluated taste of a hamburger that included their choice of condiments on a 10-point scale (10 = excellent; 1 = terrible). Hamburgers made with patties treated with 4.5 kGy were rated lower (P<.05) in taste than hamburgers made with either control patties or those treated with 3.0 kGy (6.5, 6.6, and 6.2, respectively, for 0, 3.0, and 4.5 kGy); however, all doses were rated at some level of "fair." These results imply that hamburgers made from ground beef patties irradiated under the conditions of this experiment would encounter little, if any, consumer acceptance problems at the 3.0 kGy dose and only slightly greater problems at the 4.5 kGy dose.

Clostridium algidixylanolyticum sp. nov., a psychrotolerant, xylan-degrading, spore-forming bacterium. (4/240)

A psychrotolerant Clostridium species was isolated from vacuum-packed, temperature-abused raw lamb. Colonies of this micro-organism on sheep-blood agar were circular with an entire margin, grey-white, translucent and beta-haemolytic. Cells were single, tapered, motile rods. Elliptical subterminal spores were produced in the late stationary growth phase. Spores did not cause swelling of the maternal cells. The micro-organism was obligately anaerobic. In peptone yeast extract glucose starch (PYGS) broth at pH 7.0, the micro-organism grew optimally between 25.5 and 30.0 degrees C. The temperature range for growth was 2.5-32.2 degrees C. At 26 degrees C, the micro-organism grew optimally at pH 6.8 to 7.0. The pH range for anaerobic growth was 4.7-9.1. The micro-organism was saccharoclastic, hydrolysed starch and degraded xylan. The fermentation products formed in PYGS broth were acetate, formate, lactate, ethanol, butyrate, butanol, hydrogen and carbon dioxide. The G + C content of the DNA was 38.4 mol%. Phylogenetic analyses indicated that the strain belongs to cluster XIVa of the genus Clostridium (sensu Collins et al. 1994). The new strain differed from phylogenetically related clostridia in terms of cellular fatty acid composition, soluble protein profiles and phenotypic properties. On the basis of phenotypic and genotypic characterization data, the strain was assigned to a new species, namely Clostridium algidixylanolyticum. The type strain is strain SPL73T (= DSM 12273T).

Reaction coordinates of biomolecular isomerization. (5/240)

Transition path sampling has been applied to the molecular dynamics of the alanine dipeptide in vacuum and in aqueous solution. The analysis shows that more degrees of freedom than the traditional dihedral angles, phi and psi, are necessary to describe the reaction coordinates for isomerization of this molecule. In vacuum, an additional dihedral angle is identified as significant. In solution, solvent variables are shown to play a significant role, and this role appears to be more specific than can be captured by friction models. Implications for larger molecules are discussed. (+info)

Clostridium gasigenes sp. nov., a psychrophile causing spoilage of vacuum-packed meat. (6/240)

Two psychrophilic Clostridium strains, DB1AT and R26, were isolated from incidences of 'blown-pack' spoilage of vacuum-packed chilled lamb. Vacuum packs of meat inoculated with these strains developed gas bubbles and pack distension within 14 d storage at 2 degrees C. The two main gases responsible for pack distension were carbon dioxide and hydrogen. 1-Butanol, butyric and acetic acid and butyl esters were the major volatile compounds produced by the strains in the artificially inoculated packs. The unknown strains were Gram-positive motile rods producing elliptical subterminal spores during the late-stationary growth phase. At pH 7.0, they grew from -1.5 to 26 degrees C, and their optimum growth temperature was 20-22 degrees C. At 20 degrees C, the pH range for growth was 5.4-8.9 and the optimum pH for growth was 6.2-8.6. In peptone/yeast extract broth, the organisms grew little or not at all in the absence of fermentable carbohydrates. Both strains hydrolysed gelatin, aesculin and starch. The fermentation products formed in peptone yeast extract glucose starch broth were ethanol, acetate, butyrate, lactate, butanol, carbon dioxide and hydrogen. The G+C contents of the DNA of strains DB1AT and R26 were 29.4 and 28.3 mol%, respectively. Phylogenetic analyses indicated that the strains belong to cluster I of the genus Clostridium (sensu Collins et al. 1994). The new strains differed from the phylogenetically related clostridia in cellular fatty acid composition, soluble protein profiles and phenotypic properties. On the basis of rDNA analysis and phenotypic and phylogenetic characterization, the strains were assigned to a new species for which the name Clostridium gasigenes is proposed. Strain DB1AT (= DSM 12272T) is designated as the type strain. (+info)

Lactobacillus algidus sp. nov., a psychrophilic lactic acid bacterium isolated from vacuum-packaged refrigerated beef. (7/240)

Lactobacillus algidus sp. nov. is described on the basis of 40 strains isolated as one of the predominant bacteria from five specimens of vacuum-packaged beef collected from different meat shops and stored at 2 degrees C for 3 weeks. These strains were quite uniform in the overall characteristics examined. They are facultatively anaerobic, psychrophilic, Gram-positive, non-spore-forming, non-motile, lactic acid-homofermentative rods. The cells occurred singly and in pairs on agar media and in rather long chains in broth media. They differed in several cultural and biochemical characteristics from the authentic meso-diaminopimelic acid-positive or psychrophilic lactic acid bacteria in the genera Lactobacillus, Carnobacterium and Brochothrix. The SDS-PAGE whole-cell protein pattern was clearly distinctive. DNA-DNA hybridization and phylogenetic analysis of 16S rDNA also failed to associate these strains closely with any of the validly described organisms used. The phylogenetic analysis showed that these strains are rather remotely but most closely related to Lactobacillus mali (93% sequence similarity), which belongs to the Lactobacillus casei/Pediococcus group. Therefore, these strains should be included in the genus Lactobacillus and considered to represent a new species, Lactobacillus algidus sp. nov. The type strain is M6A9T (= JCM 10491T). (+info)

Alterations in the determinants of diastolic suction during pacing tachycardia. (8/240)

In cardiomyocytes, generation of restoring forces (RFs) responsible for elastic recoil involves deformation of the sarcomeric protein titin in conjunction with shortening below slack length. At the left ventricular (LV) level, recoil and filling by suction require contraction to an end-systolic volume (ESV) below equilibrium volume (Veq) as well as large-scale deformations, for example, torsion or twist. Little is known about RFs and suction in the failing ventricle. We undertook a comparison of determinants of suction in open-chest dogs previously subjected to 2 weeks of pacing tachycardia (PT) and controls. To assess the ability of the LV to contract below Veq, we used a servomotor to clamp left atrial pressure and produce nonfilling diastoles, allowing measurement of fully relaxed pressure at varying volumes. We quantified twist with sonomicrometry. We also assessed transmural ratios of N2B to N2BA titin isoforms and total titin to myosin heavy chain (MHC) protein. In PT, the LV did not contract below Veq, even with marked reduction of volume (end-diastolic pressure [EDP], 1 to 2 mm Hg), whereas in controls ESV was less than Veq when EDP was less than approximately 5 mm Hg. In PT, both systolic twist and diastolic untwisting rate were reduced, and there was exaggerated transmural variation in titin isoform and titin-to-MHC ratios, consistent with the more extensible N2BA being present in larger amounts in the subendocardium. Thus, in PT, determinants of suction at the level of the LV are markedly impaired. The altered transmural titin isoform gradient is consistent with a decrease in RFs and may contribute to these findings. (+info)

In the context of medical terminology, "vacuum" is not typically used as a standalone term with a specific medical definition. However, it can be used in certain medical procedures or conditions in relation to creating a partial vacuum or absence of pressure. For example:

1. In surgical procedures, such as a vacuum-assisted closure, a vacuum is applied to help promote wound healing by removing fluids and infectious materials from the wound site.
2. In some cases, a therapeutic vacuum may be used to treat soft tissue injuries or conditions like lymphedema, where controlled negative pressure is applied to improve circulation, reduce swelling, and promote healing.
3. A rare medical condition called "spontaneous intracranial hypotension" can occur when there is a leak in the dura mater (the protective membrane surrounding the brain and spinal cord), causing cerebrospinal fluid to escape and creating a negative pressure or vacuum-like effect within the skull, which may result in headaches, neck pain, or other neurological symptoms.

In general, "vacuum" is not a commonly used medical term with a specific definition but can be found in relation to certain procedures or conditions where a partial vacuum or absence of pressure is involved.

Vacuum extraction, obstetrical is a medical procedure used during childbirth to help deliver the baby when there are signs of fetal distress or if the mother is experiencing exhaustion during labor. This assisted delivery technique involves the application of suction through a vacuum device that attaches to the baby's head, allowing the healthcare provider to gently pull the baby out as the mother pushes.

The vacuum extractor consists of a soft or rigid cup connected to a pump, which creates negative pressure inside the cup. The cup is placed on the fetal scalp and engaged during a contraction when the cervix is fully dilated and the baby's head has descended into the pelvis. The healthcare provider then uses controlled traction to help deliver the baby while monitoring both the mother and the infant for any signs of distress or complications.

Vacuum extraction should only be performed by experienced healthcare providers, as it carries risks such as scalp trauma, cephalohematoma (a collection of blood under the skin on the baby's head), subgaleal hematoma (a more serious type of bleeding beneath the scalp), and intracranial hemorrhage (bleeding inside the skull). Proper evaluation, technique, and monitoring are crucial to minimize these risks and ensure a safe delivery for both mother and baby.

Vacuum curettage is a medical procedure that involves the use of suction to remove tissue from the uterus. It is often used as a method of first-trimester abortion, or to treat abnormal uterine conditions such as miscarriage or retained placental tissue after childbirth. The cervix is dilated and a vacuum aspirator is inserted into the uterus to remove the contents using suction. This procedure may also be referred to as vacuum aspiration or suction curettage.

Obstetrical extraction refers to a medical procedure in obstetrics, where a fetus or a dead fetus is removed from the uterus through surgical means. This is typically performed when a vaginal delivery is not possible or safe due to various reasons such as obstructed labor, maternal or fetal distress, or prolonged pregnancy. The procedure may involve dilation and evacuation (D&E) or instrumental delivery using forceps or vacuum extractor. It is usually done under anesthesia in a hospital setting.

Obstetrical forceps are a surgical instrument used in childbirth to help deliver a baby when there are difficulties in the normal birthing process. They are a pair of curved metal instruments that resemble tongs, with each part designed to grip onto specific areas of the baby's head. The forceps are carefully applied to the baby's head during a contraction, and then used to gently guide the baby out of the mother's birth canal. This procedure is called an assisted vaginal delivery or operative vaginal delivery.

Obstetrical forceps require precise knowledge and skill to use safely and effectively, as their misuse can lead to complications such as facial injuries, skull fractures, or nerve damage in the baby. Therefore, they are typically used by experienced obstetricians in specific clinical situations, such as when the labor is prolonged, when the baby shows signs of distress, or when there is a need for a quick delivery due to maternal health concerns.

Negative-Pressure Wound Therapy (NPWT) is a medical treatment used to promote wound healing and prevent infection in acute or chronic wounds. It involves the application of controlled sub-atmospheric pressure to the surface of the wound, usually through the use of a vacuum-assisted device.

The negative pressure helps to remove excess fluid and infectious materials from the wound, while also promoting the growth of new tissue by increasing blood flow and stimulating cell proliferation. NPWT can be used in various types of wounds, including diabetic foot ulcers, pressure ulcers, surgical wounds, and traumatic injuries.

The therapy is typically administered through a sealed dressing that covers the wound and is connected to a vacuum pump. The negative pressure is applied continuously or intermittently, depending on the specific needs of the patient and the type of wound being treated. NPWT has been shown to be effective in reducing wound size, promoting healing, and improving overall clinical outcomes in many patients with complex wounds.

I'm sorry for any confusion, but "Food Packaging" is not a medical term. It is a term used to describe the process and materials used to package food products to protect them from contamination, damage, and to provide information about the product. Medical definitions are typically related to diseases, conditions, treatments, or anatomical terms. If you have any questions related to medical terminology, I'd be happy to help with those!

In medical terms, suction refers to the process of creating and maintaining a partial vacuum in order to remove fluids or gases from a body cavity or wound. This is typically accomplished using specialized medical equipment such as a suction machine, which uses a pump to create the vacuum, and a variety of different suction tips or catheters that can be inserted into the area being treated.

Suction is used in a wide range of medical procedures and treatments, including wound care, surgical procedures, respiratory therapy, and diagnostic tests. It can help to remove excess fluids such as blood or pus from a wound, clear secretions from the airways during mechanical ventilation, or provide a means of visualizing internal structures during endoscopic procedures.

It is important to use proper technique when performing suctioning, as excessive or improperly applied suction can cause tissue damage or bleeding. Medical professionals are trained in the safe and effective use of suction equipment and techniques to minimize risks and ensure optimal patient outcomes.

I'm sorry for any confusion, but "Floors and Floorcoverings" is not a medical term. It refers to the physical structures and materials used to cover floors in buildings or homes. If you have any medical terms that you would like me to define, please let me know!

Non-steroidal abortifacient agents are medications or substances that can cause abortion by interfering with the normal functioning of the hormones in the reproductive system. These agents do not contain steroids and work primarily by preventing the implantation of a fertilized egg in the uterus or by causing the shedding of the uterine lining, leading to the termination of an early pregnancy.

Examples of non-steroidal abortifacient agents include:

1. Mifepristone (RU-486): This medication works by blocking the action of progesterone, a hormone necessary for maintaining pregnancy. When used in combination with another medication called misoprostol, it can cause an abortion during the early stages of pregnancy.
2. Misoprostol: This medication is primarily used to prevent and treat stomach ulcers but can also be used as an abortifacient agent. It causes uterine contractions and cervical dilation, leading to the expulsion of the contents of the uterus.
3. High-dose estrogen and progestin: These hormones can interfere with the normal functioning of the reproductive system and cause an early abortion when taken in high doses.
4. Herbal remedies: Certain herbs, such as pennyroyal, tansy, and savin, have been used traditionally as abortifacient agents. However, their effectiveness and safety are not well-established, and they can cause serious side effects or even death when taken in large quantities.

It is important to note that the use of non-steroidal abortifacient agents for the purpose of inducing an abortion should only be done under the supervision of a licensed healthcare provider, as there are potential risks and complications associated with their use. Additionally, some of these agents may be restricted or illegal in certain jurisdictions, so it is essential to comply with local laws and regulations regarding their use.

Abdominal wound closure techniques refer to the methods used to close and repair surgical incisions in the abdomen. The goal of these techniques is to restore the integrity of the abdominal wall, minimize the risk of infection or dehiscence (wound separation), and promote optimal healing. Several abdominal wound closure techniques are available, and the choice of which one to use depends on various factors such as the size and location of the incision, the patient's individual needs and medical history, and the surgeon's preference. Here are some commonly used abdominal wound closure techniques:

1. Continuous running suture: This technique involves using a continuous strand of suture material to close the wound in a single pass. The suture is inserted through the full thickness of the abdominal wall, including the fascia (the strong connective tissue that surrounds the muscles), and then passed continuously along the length of the incision, pulling the edges of the wound together as it goes. This technique can be faster and more efficient than other methods, but it may increase the risk of infection or wound breakdown if not done properly.
2. Interrupted suture: In this technique, the surgeon uses individual stitches placed at regular intervals along the incision to close the wound. Each stitch is tied separately, which can make the closure more secure and reduce the risk of infection or wound breakdown. However, interrupted sutures can be more time-consuming than continuous running sutures.
3. Mass closure: This technique involves using a large, continuous suture to close the entire length of the incision in one pass. The suture is inserted through the full thickness of the abdominal wall and tied at both ends, pulling the edges of the wound together. Mass closure can be faster and more efficient than other methods, but it may increase the risk of infection or wound breakdown if not done properly.
4. Retention sutures: These are additional sutures that are placed deep within the abdominal wall to provide extra support and strength to the closure. They are often used in high-tension areas or in patients who are at increased risk of wound dehiscence, such as those with obesity or diabetes.
5. Layered closure: In this technique, the surgeon closes the incision in multiple layers, starting with the deepest layer of muscle and fascia and working outward to the skin. Each layer is closed separately using either interrupted or continuous sutures. Layered closure can provide added strength and stability to the closure, but it can be more time-consuming than other methods.
6. Skin closure: The final step in wound closure is to close the skin, which can be done using a variety of techniques, including staples, sutures, or surgical glue. The choice of closure method depends on several factors, including the size and location of the incision, the patient's individual needs and preferences, and the surgeon's experience and expertise.

Overall, the choice of wound closure technique depends on several factors, including the size and location of the incision, the patient's individual needs and preferences, and the surgeon's experience and expertise. The goal is to provide a strong, secure, and cosmetically appealing closure that minimizes the risk of infection, wound breakdown, or other complications.

I'm not a medical professional, but I can tell you that "housekeeping" is not a term typically used in a medical context. It generally refers to the maintenance and cleaning of living spaces or workplaces. However, in a healthcare setting, "housekeeping" may refer to the environmental services department responsible for maintaining cleanliness and infection control within the facility. This includes tasks such as cleaning patient rooms, common areas, and medical equipment to prevent the spread of infections and maintain a safe environment for patients, staff, and visitors.

Desiccation is a medical term that refers to the process of extreme dryness or the state of being dried up. It is the removal of water or moisture from an object or tissue, which can lead to its dehydration and preservation. In medicine, desiccation may be used as a therapeutic technique for treating certain conditions, such as drying out wet wounds or preventing infection in surgical instruments. However, desiccation can also have harmful effects on living tissues, leading to cell damage or death.

In a broader context, desiccation is also used to describe the process of drying up of an organ, tissue, or body part due to various reasons such as exposure to air, heat, or certain medical conditions that affect moisture regulation in the body. For example, diabetic patients may experience desiccation of their skin due to decreased moisture production and increased evaporation caused by high blood sugar levels. Similarly, people living in dry climates or using central heating systems may experience desiccation of their mucous membranes, leading to dryness of the eyes, nose, and throat.

Atmospheric pressure, also known as barometric pressure, is the force per unit area exerted by the Earth's atmosphere on objects. It is measured in units of force per unit area, such as pascals (Pa), pounds per square inch (psi), or, more commonly, millimeters of mercury (mmHg).

Standard atmospheric pressure at sea level is defined as 101,325 Pa (14.7 psi) or 760 mmHg (29.92 inches of mercury). Atmospheric pressure decreases with increasing altitude, as the weight of the air above becomes less. This decrease in pressure can affect various bodily functions, such as respiration and digestion, and may require adaptation for individuals living at high altitudes. Changes in atmospheric pressure can also be used to predict weather patterns, as low pressure systems are often associated with stormy or inclement weather.

Biological preservation is the process of preventing decomposition or decay of biological materials, such as tissues, cells, organs, or organisms, in order to maintain their structural and functional integrity for further studies, research, education, or conservation purposes. This can be achieved through various methods, including fixation, freezing, drying, or the use of chemical preservatives. The goal is to maintain the samples in a stable state so that they can be examined, analyzed, or used in experiments at a later time.

When it comes to vacuums, Dyson is the name in sleek, innovative design. (askmen.com)
The Dyson V7 Motorhead Cordless Handheld Vacuum Cleaner is a prime example. (askmen.com)
On the other hand, own-brand deals with the likes of Dyson have been a bit thin-on-the ground and sporadic, but we're holding out hope that we'll see more exclusive Cyber Monday vacuum deals appearing come Monday. (techradar.com)
Roidmi is a relative newcomer to the floorcare market, having been founded in China in 2015, and thanks to investment from smartphone brand Xiaomi, it's fast becoming a rival to the big hitters such as Dyson and Miele by offering robot vacuum s and some of the best cordless vacuums , with high-end specs at more affordable price points. (techradar.com)
To find the best robot vacuum for every type of home and lifestyle, we spoke with engineers and product managers at Dyson and iRobot, as well as tested several models to measure real-world performance. (nymag.com)
There are many cheap pet vacuums on the market that look like Dyson 's but in fact don 't even possess cyclone technology. (ipl.org)

It's a vacuum and mop combo, and it works with Alexa, so you clean all the hard floors in your home by using just your voice to control it for just $169. (techradar.com)
The Roidmi RS60 is a powerful cordless vacuum cleaner that can mop hard floors at the same time as sucking up dust and debris. (techradar.com)
As well as an arsenal of attachments, including an electric mattress brush and an extension hose, the vacuum cleaner also comes with a clip-on mopping attachment complete with a small water tank, enabling you to vacuum and wash hard floors at the same time. (techradar.com)
The Roidmi RS60 is a compact and lightweight cordless vacuum cleaner that can wash as well as suck up dust when used on hard floors. (techradar.com)
These convergence devices, which allow you to sweep, vacuum, and mop your floors simultaneously, are a game-changer. (popsci.com)
Fancier models can even have features like camera-based obstacle detection and smart room mapping and automation - and a few will mop your floors after vacuuming. (nymag.com)
Part of effectively replacing that cleaning system is being able to trust that your robot vacuum won't miss any spots in its cleaning cycles, and that your floors will be at least as clean as if you'd done the job yourself. (nymag.com)
But the good news is that you don't have to shell out for a super high-end vacuum or a bulky and heavy appliance to maintain squeaky-clean floors. (popsci.com)
The vacuums on this list include lightweight, versatile, and easy-to-use cleaners that cover everything from hard-wood floors and thick, plush carpets to car seat crevices and crown molding. (popsci.com)
Keep the following things in mind when selecting the best cheap vacuums to keep your floors and more dust-free. (popsci.com)
Vacuuming the floors is an essential and recurring chore in keeping your home clean, but few homeowners enjoy this task. (theday.com)
A central vacuum system can make it a little easier to clean up your floors. (theday.com)
Shop vacuum cleaners clean either liquid spills or dirt and dust from floors and surfaces. (grainger.com)

This reduces clogging in the filters and ensures your vacuum doesn't lose suction power. (askmen.com)
According to Roidmi the RS60, which is its latest cordless vacuum cleaner, offers 65% more suction power than its previous top-of-the-range cleaner, the Roidmi S1E (although that doesn't have a mopping function), and has a 50W brushless motor that's more energy-efficient than those in previous models. (techradar.com)
Like many of the best vacuum cleaners , the Roidmi RS60 has three levels of suction power, although you'll have to manually switch between these, unlike on some rivals which automatically adjust the power level to suit the type of floor you're cleaning. (techradar.com)
The excellent food sealer produces great suction power of Max 80kPa to extract all air from the bag, ensuring the fresh of your food fresh and the high efficiency vacuum sealing. (shopping.com)
Although suction power is one of the primary metrics flaunted by traditional vacuum manufacturers, things like the vacuum's brushes are just as important when it comes to picking up debris. (nymag.com)
Meanwhile, a vacuum with a slightly weaker suction power but more effective brushes will clean up more debris and require fewer trips back to the charging station. (nymag.com)
One five-star review singled out the suction power , stating: "This is an excellent vacuum cleaner for someone looking for a light and portable vacuum but does not want to compromise on the suction power. (yahoo.com)
It likely goes without saying, but a crucial component of any good vacuum cleaner is suction power. (yahoo.com)

This is a big saving on a handheld vacuum which was already reasonably priced. (techradar.com)
Like many of its rivals, you can convert RS60 into a handheld vacuum by detaching the canister from the main wand and cleaning head and attaching one of the many tools, which include an extension hose, a crevice tool, a pet hair attachment and even an electronic mattress brush, to the bottom of the canister. (techradar.com)

The Roidmi RS60 cordless vacuum cleaner is priced at $661 / £579 / AU$966, and is available worldwide from Harrods . (techradar.com)
The Roidmi RS60 has a magnetic add-on to its main cleaning head that can be used for mopping, with a 5 fl oz / 150ml water tank within the attachment, and the dust canister has a 0.12-gallon / 0.55-liter capacity, which Roidmi says is 35% larger than the ones on its previous cordless vacuum cleaners. (techradar.com)
Whether you enjoy the hands-on cleaning power of a cordless vacuum or you want to sit back and let the robots do the work, there's something in this sale for you. (yahoo.com)
The key number with the Proscenic P10 Cordless Vacuum Cleaner is "4": four adjustable suction modes, four attachable cleaning tools, and a four-stage complete sealing filtration system. (yahoo.com)

Avid Armor's vacuum sealing bags are ideal for storing food, sous vide cooking, freezing, and so much more. (shopping.com)

Often we need to predict the time it's going to take for a vacuum pump to evacuate a chamber or process from atmospheric pressure down to the operating vacuum. (atlascopco.com)
The actual flow rate is a measure of the volume of gas displaced through the inlet of a vacuum pump in a given time. (atlascopco.com)
This is a type of high vacuum pump intended to lower costs by not requiring much specialized hardware. (halfbakery.com)
The low vacuum chamber is evacuated by a conventional backing pump like a sliding-vane vacuum pump (which is already inexpensive, and can easily be bought used). (halfbakery.com)
The differential solubility pump is therefore a substitute for other high vacuum pumps like the turbomolecular pump and the diffusion pump. (halfbakery.com)
To save space, this pump could also be made in a form that doesn't need a low vacuum chamber, just a backing pump, by substituting a (coiled? (halfbakery.com)
Vacuum pump oils meet the first requirement, but I don't know how well they dissolve gases. (halfbakery.com)
In sliding-vane pumps, it causes problems when the oil dissolves process gas, which is why a sliding-vane vacuum pump will usually have a 'gas ballast valve' that just lets in a bit of air to flush out the dissolved process gas (at the expense of achieving a worse vacuum on the suction side), which implies that they do dissolve at least some gases at least somewhat. (halfbakery.com)
Either way, though, this pump will probably not pump all gases equally well, which is a limitation that applies to the current options as well e.g. virtually all vacuum pumps are bad at evacuating helium. (halfbakery.com)
In that case, you wouldn't need a low vacuum backing pump at all, just a supply of eluent gas free of any gases soluble in the solvent. (halfbakery.com)
For optimal results, we recommend using the QIAvac 24 Plus and QIAvac 96 together with the QIAvac Connecting System and a Vacuum Pump . (qiagen.com)
For optimal results, we recommend using the QIAvac HiSpeed LS together with a Vacuum Pump . (qiagen.com)
In combination with the QIAvac Connecting System (vacuum connecting system) (see figure An integrated system for various applications. For connecting the QIAvac 24 Plus and Vacuum Pump "> "An integrated system for various applications" ), the QIAvac 24 Plus can be used as a flow-through system. (qiagen.com)
Thoughts on vacuum pump equipment for kiln drying. (woodweb.com)
I need to find a place to buy a used liquid ring vacuum pump using water at a low price. (woodweb.com)
It needs to be a vacuum pump that can handle the moisture (and chemicals) from the wood drying. (woodweb.com)
Most vacuum pumps cannot handle this, and that is why I am looking for an economical liquid ring pump, or any style that could withstand moisture, etc. (woodweb.com)

As the vacuum captures dirt and debris, it passes through a filter while the multi-cyclonic suction helps keep dirt away from the motor and post-motor filter, for extended durability. (bestbuy.com)
A good vacuum cleaner isn't just a device for sucking up dirt - it's an integral part of the homestead. (askmen.com)
A vacuum that has the power and tech to reach dirt in otherwise unreachable places - and to pick up the dirt that. (askmen.com)
The Vax Mach Air Upright Vacuum Cleaner uses multi-cyclonic technology, which separates dust and dirt particles from the air path. (askmen.com)
Most good vacuums suck up more dust, dirt, and allergens than they spit out. (webmd.com)
While portable vacuum cleaners have their own canisters to store dust and dirt, central vacuum cleaners keep this receptacle and the motor in a single location, usually in the basement or garage. (theday.com)

Anyway, it consists of a circuit for pumping this liquid (the solvent) around, where the liquid is exposed to the surroundings in two places: inside the high vacuum chamber and inside the low vacuum chamber. (halfbakery.com)
This is to make the solvent in the tray in the high vacuum chamber cold, and the solvent in the tray in the low vacuum chamber hot. (halfbakery.com)
The result of this is that gas molecules that hit the cold solvent in the high vacuum chamber are likely to be dissolved in it, and gas molecules dissolved in the solvent are driven out of it in the low vacuum chamber. (halfbakery.com)
With the solvent being continuously pumped between the two chambers, this results in transport of gas molecules from the high vacuum chamber to the low vacuum chamber, producing the high vacuum. (halfbakery.com)
