summer and when the sun is shinning
Simply because it may be some time before the sample arrives back at the lab. Furthermore, if you collect it in a container that is not adequate, you may introduce contamination on sampling. Decomposition may be an issue also, if stored incorrectly.
In the sense that EVERYTHING in your head is a model ... the answer is all the time.
She saw her setting time in her watch after every 10 minutes. This is a sample sentence using phrase Setting Time.
The best time of the day to vacuum is in the morning.
It can be. The first void of the morning is usually the most concentrated, which helps when trying to do pregnancy tests or microalbumin-creatinine ratios.
Samples for what? If you are sampling for the basic test that most extension offices perform, it doesn't matter.
summer time
In the mornings.
The best time to collect marine organisms is when it is low tide. If it is high tide there wouldnt be anything washed ashore
The best time of day for a proper urine sample is first thing in the morning. This is because the urine is more concentrated then.
The best time i always go is the 1st October, conkers are fully grown by then!!!
If it's too time consuming, expensive or otherwise impractical to collect data from the entire population of interest you can derive equally valid results from a random representative sample of adequate size. This saves time, money and other resources.
DefinitionRoutine sputum culture is a test of secretions from the lungs and bronchi (tubes that carry air to the lung) to look for bacteria that cause infection.Alternative NamesSputum cultureHow the test is performedYou will cough deeply and spit any sputum into a sterile cup. The sputum is then taken to the laboratory. There, it is placed in a special substance (medium) under conditions that allow the bacteria or fungi to grow.How to prepare for the testDrinking a lot of water and other fluids the night before the test may help to get the sample.How the test will feelYou will need to cough. Sometimes the health care provider will tap on the chest to loosen deep sputum. There may be a steam-like mist to inhale to help you cough up the sample.Why the test is performedThe culture is done on the sputum to help identify the bacteria that are causing an infection in the lungs or airways (bronchi).Normal ValuesIn a normal sputum sample there will be no disease-causing organisms present.What abnormal results meanIf the sputum sample is abnormal, the results are called "positive." Identifying disease-producing organisms may help diagnose:BronchitisLung abscessPneumoniaTuberculosisOther conditions under which the test may be performed:Aspiration pneumoniaAtypical mycobacterial infectionAtypical pneumoniaBlastomycosisBronchiectasisCoccidioidomycosis; acute (primary) pulmonaryCoccidioidomycosis; chronic pulmonaryCoccidioidomycosis; disseminatedCryptococcosisDisseminated tuberculosis (infectious)Histoplasmosis; acute (primary) pulmonaryHistoplasmosis; chronic pulmonaryHospital-acquired pneumoniaMycoplasma pneumoniaPlaguePulmonary aspergilloma (mycetoma)Pulmonary aspergillosis; invasive typePulmonary tuberculosisViral pneumoniaWhat the risks areThere are no risks with this method of obtaining a sample.Special considerationsSometimes a Gram stain or AFB stain of the sputum done at the same time can help make the diagnosis.
An event sample is data points captured for a single event. A time sample are data points capture over a specific period of time.
Simply because it may be some time before the sample arrives back at the lab. Furthermore, if you collect it in a container that is not adequate, you may introduce contamination on sampling. Decomposition may be an issue also, if stored incorrectly.
Because it would usually be prohibitively expensive and time consuming to collect information from every single member of the population and because the law of large numbers is sufficiently robust to allow most characteristics of a population to be measured with sufficient accuracy from a sample.
It usually presents with a cough , which may or may not produce sputum. In time, more sputum is produced that is streaked with blood. The cough may be present for weeks or months and may be accompanied by chest pain and shortness of breath.
