Mussel beds are an important habitat in many coastal systems, harboring a high diversity of biota. They threatened by anthropogenic impacts that affect mussels and their associated assemblages. Pollution, harvesting, trampling, dredging trawling major threats faced these communities. Most the studies on effects such mussel overlook fauna. Since very resilient, especially to pollution, fauna can...

Abstract A late early Maastrichtian dinosaur trampling site is reported from the Farrokhi Formation of Khur area, Central Iran. The largely indeterminate footprints, some which may represent undertracks, can be classified as natural moulds (i.e. concave epireliefs) bordered by a raised rim displaced sediment. They reach diameters up to 0.5 m and were impressed under very shallow subaerial condi...

Monitoring and predicting crowd movements in indoor environments are of great importance management to prevent crushing trampling. Existing works mostly focused on individual trajectory forecasting a less crowded scene, or counting density estimation. Only very few predict the distribution. However, this study is failing realize multi-step prediction exploits only heatmaps modality ignores info...

The compaction of soils used for crop production is becoming an increasingly important consideration in South Africa following the shift towards reduced tillage and increased mechanisation of in-season operations and harvesting. The intensification of dairying has also been found to have a deleterious effect on soil quality, particularly in terms of compaction by trampling, which results in los...

Three new non-indigenous springtail species are recorded in recent collections made on Deception Island, South Shetland Islands, maritime Antarctic: Deuteraphorura (Deuteraphorura) cebennaria (Gisin) (Collembola: Onychiuridae), Mesaphorura macrochaeta Rusek (Tullbergiidae), and Proisotoma minuta Axelson (Isotomidae). One of these, D. (D.) cebennaria, is described. Additionally, two new indigeno...

Cervical cancer remains an important public health problem in developing countries where over 80% of the global burden occurs annually but screening has been ineffective. In a polygamous country like Ghana with a high incidence of cervical cancer but no national screening program, the Human Papilloma Virus (HPV) vaccine presents a unique opportunity to reduce the burden of HPV infection and cer...

Many observations of the dynamics of pedestrian crowds, including various self-organization phenomena, have been successfully described by simple many-particle models. For ethical reasons, however, there is a serious lack of experimental data regarding crowd panic. Therefore, we have analyzed video recordings of the crowd disaster in Mina/Makkah during the Hajj in 1426H on 12 January 2006. They...
