A urine test strip or dipstick test is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample. The test can often be read in as little as 60 to 120 seconds after dipping, although certain tests require longer. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases. The analysis includes testing for the presence of proteins, glucose, ketones, haemoglobin, bilirubin, urobilinogen, acetone, nitrite and leucocytes as well as testing of pH and specific gravity or to test for infection by different pathogens. The test strips consist of a ribbon made of plastic or paper of about 5 millimetre wide, plastic strips have pads impregnated with chemicals that react with the ...

The DrugWipe is a test used to wipe surfaces for traces of drug residue. It may also be used for sweat or saliva tests of individuals. Officers at the roadside can quickly screen (using saliva) for drivers suspected of being under the influence of an illegal drug. DrugWipe was named a finalist in the 2011 Cygnus Law Enforcement Group Innovation Awards competition. The DrugWipe 6+ (saliva only) test was entered under the category of 'Traffic Enforcement'. The test is accomplished by wiping a small moist wiping fleece on a surface, or on the forehead, palm, or tongue of an individual. It can detect cannabis, cocaine, crack cocaine, heroin, morphine, amphetamines, MDMA, and benzodiazepines. Immuno assay strips containing antibodies bind to components of the different drugs. The Center for Forensic Research & Education performed an independent laboratory evaluation of 10 on-site oral fluid devices. DrugWipe was the #1 rated oral fluid device in this study, performing at 100% accuracy, with zero ...
Wound closure strips are porous surgical tape strips which can be used to close small wounds. They are applied across the laceration in a manner which pulls the skin on either side of the wound together. Wound closure strips may be used instead of sutures (stitches) in some injuries, because they lessen scarring and are easier to care for. Wound closure strips are often referred to using the genericized trademark Steri-Strips, the brand name used by 3M's Nexcare. The precursor to the Steri-Strip was 3M's Micropore brand of microporous surgical tape. Wound closure strips are ideal for use in highly contoured areas or areas of musculoskeletal movements, such as joints. They are also for use in areas where swelling, edema, hematomas, or bloating may occur.[citation needed] Additionally, they provide wound support following early suture or staple removal. Wound closure strips may also be applied ...
... (SBP) is the development of a bacterial infection in the peritoneum causing peritonitis, despite the absence of an obvious source for the infection. It occurs almost exclusively in people with portal hypertension (increased pressure over the portal vein), usually as a result of cirrhosis of the liver. It can also occur in patients with nephrotic syndrome. The diagnosis of SBP requires paracentesis (aspiration of fluid with a needle) from the abdominal cavity. If the fluid contains bacteria or large numbers of neutrophil granulocytes (>250 cells/µL) (a type of white blood cells), infection is confirmed and antibiotics are required to avoid complications. In addition to antibiotics, infusions of albumin are usually administered. Signs and symptoms of spontaneous bacterial peritonitis include fevers, chills, nausea, vomiting, abdominal tenderness, and general malaise. Affected individuals may complain of abdominal pain and worsening ascites. Thirteen percent of ...
... is the presence of red blood cells in the urine. Visible hematuria, also known as gross hematuria, is easily identified, as it causes red or brown discoloration of the urine. Microscopic hematuria is invisible to the naked eye and is often found incidentally on urinalysis or urine dipstick. Any part of the kidneys or urinary tract (ureters, urinary bladder, prostate, and urethra) can leak blood into the urine. The causes of hematuria are broad, ranging from urinary tract infection to kidney stones to bladder cancer. Microscopic hematuria is found regularly on routine urinalysis, with a prevalence between 0.18% and 37%. Some studies have shown increased incidence with age and female sex, but others did not show a correlation. In many people, no specific cause is found. Cancer of the kidney, prostate, bladder, or testes is found in 5% of people with microscopic hematuria and up to 40% of those with visible hematuria. Hematuria is common in pediatric populations, with a prevalence of ...
A postprandial glucose test is a blood glucose test that determines the amount of a type of sugar, called glucose, in the blood after a meal. Glucose is mainly made from carbohydrate foods. It is the main source of energy used by the body. Normally, blood glucose levels increase slightly after eating. This increase causes the pancreas to release insulin, which assists the body in removing glucose from the blood and storing it for energy. People with diabetes may not produce or respond properly to insulin, which causes their blood glucose to remain elevated. Blood glucose levels that remain high over time can damage the eyes, kidneys, nerves, and blood vessels. A 2-hour postprandial blood glucose test ("2 hour p.c. blood glucose test", etc.) measures blood glucose exactly 2 hours after eating a meal, timed from the start of the meal. By this point blood sugar has usually gone back down in healthy people, but it may still be elevated in people with diabetes. Thus, it serves as a test of whether a ...
Composers of the Mannheim school introduced a number of novel ideas into the orchestral music of their day: sudden crescendos - the Mannheim Crescendo (a crescendo developed via the whole orchestra) - and diminuendos; crescendos with piano releases; the Mannheim Rocket (a swiftly ascending passage typically having a rising arpeggiated melodic line together with a crescendo);[2] the Mannheim Roller (an extended crescendo passage typically having a rising melodic line over an ostinato bass line); the Mannheim Sigh (a mannered treatment of the Baroque practice of putting more weight on the first of two notes in descending pairs of slurred notes);[citation needed] the Mannheim Birds (imitation of birds chirping in solo passages); the Mannheim Climax (a high-energy section of music where all instruments drop out except for the strings, usually preceded by a Mannheim Crescendo); and the Grand Pause where the playing stops for a moment, resulting in total silence, only to restart vigorously. The ...
Two main methods are used to prepare papier-mâché. The first method makes use of paper strips glued together with adhesive, and the other uses paper pulp obtained by soaking or boiling paper to which glue is then added. With the first method, a form for support is needed on which to glue the paper strips. With the second method, it is possible to shape the pulp directly inside the desired form. In both methods, reinforcements with wire, chicken wire, lightweight shapes, balloons or textiles may be needed. The traditional method of making papier-mâché adhesive is to use a mixture of water and flour or other starch, mixed to the consistency of heavy cream. Other adhesives can be used if thinned to a similar texture, such as polyvinyl acetate-based glues (wood glue or, in the United States, white Elmer's glue). Adding oil of cloves or other additives such as salt to the mixture reduces the chances of the product developing mold. For the paper strips method, the ...
There have been several technical applications for the Möbius strip. Giant Möbius strips have been used as conveyor belts. Such belts last longer because the entire surface area of the belt gets the same amount of wear. Möbius bands have also been used as continuous-loop recording tapes (to double the playing time). Möbius strips are common in the making of fabric computer printer and typewriter ribbons. There, they allow the ribbon to be twice as wide as the print head while using both half-edges evenly. A device called a Möbius resistor is an electronic circuit element which has the property of canceling its own inductive reactance. Nikola Tesla patented similar technology in the early 1900s:[5] "Coil for Electro Magnets" was intended for use with his system of global transmission of electricity without wires. The Möbius strip is the configuration space of two unordered points on a circle. Consequently, in music theory, the space of all two note chords, known as dyads, ...
Detection of human chorionic gonadotrophin (hCG) in urine or serum is an easy first method of diagnosis of pregnancy. hCG can be detected as early as the sixth day after conception. hCG is also an important tumor marker because it is produced by some kinds of tumor, such as: seminoma, choriocarcinoma, germ cell tumors, hydatidiform mole formation, teratoma with elements of choriocarcinoma, and islet cell tumor Pregnancy detection kits containing a strip or card impregnated with anti-hCG globulin are readily available. The test is executed by immersing the proper end of the strip in urine or sprinkling three drops of urine on the indicated site of a card. The result is readable within two to three minutes ...
... is made from the stem of the papyrus plant, Cyperus papyrus. The outer rind is first removed, and the sticky fibrous inner pith is cut lengthwise into thin strips of about 40 cm (16 in) long. The strips are then placed side by side on a hard surface with their edges slightly overlapping, and then another layer of strips is laid on top at a right angle. The strips may have been soaked in water long enough for decomposition to begin, perhaps increasing adhesion, but this is not certain. The two layers possibly were glued together.[19] While still moist, the two layers are hammered together, mashing the layers into a single sheet. The sheet is then dried under pressure. After drying, the sheet is polished with some rounded object, possibly a stone or seashell or round hardwood.[20] Sheets, or kollema, could be cut to fit the obligatory size or glued together to create a longer roll. The point where the kollema are joined with glue is ...
