Scale formation and well plugging due to the incompatibility of injected waters is a critical field problem in oil recovery. A water injection process was successfully performed when the identification of the source of water, water quality considerations, and laboratory compatibility tests were considered. When different waters are mixed, it is necessary to evaluate their compatibility prior to...

Coagulation-flocculation followed by sedimentation and filtration is the most commonly used water treatment process , in which turbidity or particles removal is strongly dependent on proper coagulant dosage, effect of pH ,effect of time, jar test and settling column tests were perform. In the method the seeds were treated with different solvents of NaCl and NaOH to extract the active coagulant ...

German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae), catch by five types of traps and modifications of each, were tested under controlled laboratory conditions. Cockroach catch differed significantly among traps. Lo-line trap caught the greatest number of cockroaches in the test arena for each size class (23% small nymphs, 39% of gravid females, and 60% of other size classes ...

In the development of digital communication and information theory, every channel decoding rule has resulted in a revolution at the time when it was invented. In the area of information theory, early channel coding theorems were established mainly by maximum likelihood decoding, while the arrival of typical sequence decoding signaled the era of multi-user information theory, in which achievabil...

Measurement of the dynamic kinetics involved in opening a jar may enable health care professionals to understand and train individuals in optimal hand/grip mechanics. This technical note details the design, validity, and reproducibility testing of a mimetic jar capable of measuring the forces and moments and isolated digital forces applied to the lid of the jar. An ecological jar instrument was...

For the first time, a jar of embalming rejects was studied in search for helminth parasite eggs. This kind of jar was used to put discarded material by Egyptian embalmers during mummification process. Ascaris lumbricoides and Taenia saginata eggs were found in the linen and strip fragment contents of the jar, dated of 2,715-2,656 years ago.

Back ground: Acid fast bacilli (AFB) positivity using modified Ziehl Neelsen (MZN) staining and jar method was studied in sputum samples obtained by spot morning (SM) and same day (SS2) approaches. Methods: Three specimens (spot, second spot and morning) were collected in 252 patients, duplicate smears were prepared and stained by MZN staining and jar method. Results: Smear positivity was 34 (1...
