Artificial reefs are used to compensate the destruction of marine ecosystems. In the present study, the effects of artificial reefs were compared to natural sites. For this purpose, five treatments including four different forms (Reef ball (R), Laneh Mahi (L), used materials (U) and R+L+U) of artificial reefs and one control were established. The reefs were deployed at Bandar Lengeh, the Pers...

The Great Lakes basin is of radiologic interest due to the large population within its boundaries that may be exposed to various sources of ionizing radiation. Specific radionuclides of interest in the basin arising from natural and artificial sources include 3H, 14C, 90Sr, 129I, 131I, 137Cs, 222Rn, 226Ra, 235U, 238U, 239Pu, and 241Am. The greatest contribution to total radiation exposure is th...

Introduction: Artificial and natural radionuclides exist in the environmental materials, such as water, soil, rocks, and plant as well as in animals and human body tissues. Therefore, human being and environment are at constant radiation exposure. Regarding this, the present study aimed to determine the specific activities of radionuclides and perform the risk assessment wheat and barley sample...

Natural and artificial lakes provide multiple cultural ecosystem services (CES), but they are largely underrepresented in CES assessments, which mostly focus on individual large lakes. Social media data may offer an opportunity to analyse of at regional scales. This study therefore aims exploring the use photos uploaded photo-sharing platform Flickr for analysing 2,807 European Alps. We (1) exp...

A large number of natural and artificial water sources are found on the territory Zhambyl region. This is due to fact that in located mountainous region, names rivers, lakes, streams, wells with rich reserves resources often found, nature hydrological objects clearly indicated. It can be said terms defining geographical characterize have an ecological basis. Natural played important role econom...

In the present work, an artificial neural network (ANN) model was used to study the quantitative structure retention relationship (QSRR) of retention index (RI) of some volatile compounds in natural cocoa and conched chocolate powder. Molecular structural descriptors are selected using genetic algorithm to construct the nonlinear QSRR models, kernel partial least squares PLS (KPLS) and Levenber...

The Fishery Research Program (FRP) of the Great Lakes Fishery Commission includes as a research theme area “The Human Dimensions of Great Lakes Fisheries Management.” The term human dimensions refers to how and why humans value natural resources, how humans want resources managed, and how humans affect or are affected by natural resources management decisions. Human dimensions inquiries strive ...
