In Iran, using the hand excavated pits (wells) have been more common compared to other countries. As a matter of fact, recent years, utilizing the dynamic probing test (DPT) in these types of pits has been significantly developed in Iran. This is while the standard state of doing this test is from the ground level. In this work, the dynamic probing test is carried out in two similar wells with ...

River bed sand and gravel are utilized more than mountain materials due to their availability and closeness to the transit roads and sites of usage. Excessive and non-technical extraction of gravel and sand bring a kind of interference in them, leading to many negative consequences. Therefore, presenting solutions to reduce these impacts and infilling mining pits are essential. In this researc...

khanghah gilvan cemetery is located in khalkhal, in the iranian province of ardebil. this cemetery came into light during a highway construction project in khanghah village. until now, three archeological excavations, under the author’s supervision, have been carried out in this cemetery that has resulted in burials from the middle bronze age up to parthian period.   among the excavated burial...

Stability analyses are routinely performed in order to assess the safe and functional design of an excavated slope (e.g. open pit mining, road cuts, etc.), and/or the equilibrium conditions of a natural slope. The analysis technique chosen depends on both site conditions and the potential mode of failure, with careful consideration being given to the varying strengths, weaknesses and limitation...

Stingrays are an important part of the biomass of the fishes in shallow coastal ecosystems, particularly in inter-reefal areas. In these habitats, they are considered keystone species – modifying physical and biological habitats through their foraging and predation. Here, we quantify the effects of bioturbation by rays on sand flats of Ningaloo Reef lagoon in Western Australia. We measured the ...

Archaeological evidence for the preparation of preserved fish is common. Preserving allowed stockpiling temporary abundance food created by good catches and seasonal plenty. In traditional societies, majority caught are later use rather than consumed fresh. Ethnographic information from southeast Arabia, wider region, storage provides interesting details process. not usually stored product itse...

A series of centrifuge model tests were conducted to study the interaction between successively constructed adjacent foundation pits. The stress, deformation, and earth pressure on retaining structures settlement soil two pits during successive construction investigated by a comprehensive instrumentation program. To reveal effect sequence, both stress deformation compared. results showed that s...

The excavated type of rhomboid fossa of the clavicle is a relatively neglected anatomical structure that can potentially cause diagnostic problems. Its unilateral occurrence may be confused by the physician as avascular necrosis, osteomyelitis, or even a tumour. We studied 80 routine chest radiographs and identified the clavicles with excavated type of rhomboid fossa. The sex, sidedness, and ha...

Takkar B, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221967 Description A 6-year-old boy presented as a known case of developmental glaucoma and was using topical travoprost in the right eye (RE) since 1 year. Highest recorded intraocular pressure (IOP) was 24 mm Hg in RE, whereas central corneal thickness was 540 μm. Visual acuity was 6/6 in both eyes. On examination, the anterior segment ...
