Sand flies belonging to the genus Sergentomyia Franca & Parrot, 1920, are hematophagous insects feeding mostly on reptiles and birds, but some species feed also on mammals including humans. Sergentomyia spp. frequently comprise the vast majority of sand flies trapped along with Phlebotomus spp., the vectors of mammalian leishmaniasis. Within the framework of a project on the ecology and transmi...

Premise of the study: The first microsatellite primers were developed for Protium subserratum (Engl.) Engl., a widespread Amazonian tree, to investigate genetic differentiation between populations found on clay, brown-sand and white-sand soils. Methods and Results: Seventeen primer pairs were identified from two individuals of Protium subserratum, found on white-sand and brown-sand soil types. ...

Functional connectivity, the degree to which the landscape facilitates or impedes movement, depends on how animals perceive costs and benefits associated with habitat features and integrate them into a movement path. There have been few studies on functional connectivity in marine organisms, despite its importance for the effectiveness of Marine Protected Areas. In this study, we asked how open...

Several cases of recurrent stone formation caused by a surgical material as a nidus have been reported. Recently, we experienced one case in which a migrated metal stent might have been served as a nidus for common duct stone formation. The diagnosis was confirmed by ERCP, the stone was successfully removed with endoscopic therapy. Six years ago, she had undergone a lithotripsy using a percutan...

Stemflow from Japanese red cedar (Cryptomeria japonica) enters forest soil at a low pH. We evaluated the responses of the root system of Japanese red cedar saplings to acidic conditions, used to simulate this situation, in two different growth media, a brown forest soil (BS) and a Yahagi sand (YS). Soils were acidified by the addition of solutions at pH 2.0, 3.0 and 5.5 (control). Root morpholo...

Based on experiments of C30 concrete with manufactured sand, this paper studied the workability and compressive strength sand 7 different fineness modulus weight fractions (0%, 2%, 4%, 6%, 8%, 10%) stone powder. The results show that powder content in gradation parameters have great effects performance. When is about 2.8, can be improved. As increases, firstly increase then decrease, optimal fr...

Microorganisms can be responsible for the destruction of cultural heritage, together with several environmental conditions, ageing and the chemical structure of substrate. There is a number of reviews giving a comprehensive picture of the role of microorganisms in the degradation of art objects, such as paintings, stone, wood, paper, masonry, leather, parchment, glass and metal (Bock and Sand, ...

Traditionally soil, stone aggregates, sand, bitumen, cement etc. are used for road construction. Natural materials being exhaustible in nature, its quantity is declining gradually. Also, cost of extracting good quality of natural material is increasing. Concerned about this, the scientists are looking for alternative materials for highway construction, and industrial waste product is one such c...

Since 1988 we have been excavating at Giza, 350 m south of the Great Sphinx and south of the gigantic stone Heit el-Ghurob ("Wall of the Crow"). The concession, 650 m north-south and 250 m east-west (16 ha), extends from the bottom of the slope where Zahi Hawass has excavated the "workers' cemetery" in recent years, to the modern paved road and houses of Nazlet es-Semman and Kafr Gebel. A subst...
