BACKGROUND Lung biopsy through the airways by using a flexible bronchoscope (transbronchial lung biopsy: TBLB) is a suitable method for obtaining tissue specimens. This study aimed at evaluating the factors influencing TBLB results in order to increase the diagnostic power of this method. MATERIALS AND METHODS This was a prospective double blind observational study. We had a total of 44 patie...

In this paper, the effect of contact angle, density, and size on the orientation, stability, and assembly of floating cubes was investigated. All the cubes tested were more dense than water. Floatation occurred as a result of capillary stresses induced by deformation of the air-water interface. The advancing contact angle of the bare acrylic cubes was measured to be 85°. The contact angle of th...

Pigeons are omnipresent birds which belong to the order, Columbiformes and cover a large part of every town city, worldwide. Among parasites pigeons, Capillaria is found be more prevalent in them after Eimeria. These worms penetrate deeply intestinal mucosa leading haemorrhages epithelial necrosis thereby presenting clinical disease death occurs if left untreated. The major purpose this study w...

Thirty soil samples were collected from fields that have been used for cultivating watermelons and canning tomatoes over 10 years. The microplastics (MPs) within these separated with a density floatation method the use of sieves filters. found black originated agricultural mulch film (BMF) in cultivations. ATR-FTIR spectroscopy revealed are same material as virgin BMF polyethylene blank. SEM im...

The enrichment of polymetallic sulfide ore is a complex task. Fine grinding carried out to reveal useful minerals, resulting in the formation microparticles. It difficult achieve floatation microparticles and fine minerals are lost with flotation tailings. problem microparticle can be solved by using air bubbles smaller than 50 µmin for process. Water-air microemulsion (WAME)of frothersolution ...

During the winter and summer of 2019, eight study sites in eastern Libya were used to establish meiofauna diversity Southern Mediterranean Sea's near-shore sandy bottom surf region. The physicochemical characteristics surface water at mostly similar. Seventeen taxa floatable (extracted from sediment samples by floatation) identified, sixteen during ten summer: By number individuals per taxon, N...

Current pharmaceutical situation focuses on the preparation of gastro-retentive floating drug delivery system (GRFDDS). This systems has gained noteworthy interest in past decades. These are low density that float over gastric contents and remain buoyant stomach for a prolonged period time without affecting emptying rate. GRFDDS is used to delay residence stomach. The controlled retention solid...
