In industry, liquids such as water and chemicals are used in various processes. The amount of such liquids stored can be found by measuring level of the liquid in a container or tank. The level affects not only the quantity delivered but also pressure and rate of flow in and out of the container. Often the tanks are so coupled together that the levels interact and exhibits a nonlinear behaviour...

In Indonesia, where diarrhea remains a major cause of mortality among children <5 years, the government promotes boiling of drinking water. We assessed the impact of boiling on water quality in South Sulawesi. We surveyed randomly selected households with at least one child <5 years old in two rural districts and tested source and stored water samples for Escherichia coli contamination. Among 2...

We developed a simple and effective method for collecting a large quantity of buccal cell DNA in school-based studies of seventh-grade and older children. Seventh-grade students at schools in Wuhan, China brushed each buccal surface with a soft toothbrush and then rinsed with 10 ml of water. We added 5 ml of 99% ethanol to preserve the sample. Among 1563 samples transported at room temperature ...

oriental hybrid lily “arabian red” mother scales were stored in moist cocopeat and perlite (1:1) for 3 or 5 months at 25 ̊c. the numbers of scale bulblets per mother scale were nearly identical in two durations. increasing storage duration promoted the growth of roots (number and length) and no. scales per scale bulblets. and, diameters of scale bulblets were more in longer storage duration (5 m...

it is assumed in most of the existing models that the items can be stored for an unlimited time to meet the future’s demand and their quality and quantity does not change during that period. nevertheless there are special kinds of products which deteriorate or become unusable (such as food products, alcohol, medicines, etc.). therefore if the rate of deterioration is significantly high, the imp...

Optimal recovery of nucleic acids from formalin-fixed paraffin-embedded (FFPE) tissues is highly dependent on a series of pre-extraction steps, mainly related (but not limited) to fixation. The aim of our study was to investigate if the storage period of the FFPE blocks had a significant effect on the isolated DNA. We examined the quantity and purity of the isolated DNA from 83 FFPE blocks, cor...

-Water resources are being, over decades, intensively over explored and polluted, and it is estimated that in a few years, it is reached highly values of water stress in Europe. Portugal is already in the ranking of countries with medium water stress (10-20%). To avoid the deterioration of this situation it is imperative to consider different approaches of water management, such as water reuse ...

The object of analysis in this study is the brain which has brain edema. Brain edema is tissue that stores overabundantly CSF (Cerebrospinal Fluid) in cells. It forms in brain tissue and appears as white part in the image of MRI. However, as the image shows only the state that CSF is stored, it gives us no information on the direction or quantity of CSF flow flux. Therefore, we study the flow o...
