Shakeel, A. (author)The nautical bottom (the level at which contact with a ship’s keel causes either damage or unacceptable effects on controllability and manoeuvrability of a ship) should be associated to a measurable physical characteristic. Bulk density is typically used as a criterion for nautical bottom by many ports worldwide. However, the rheological...doctoral thesis 2022

Rizwan, Komal (author), Majeed, Ismat (author), Bilal, Muhammad (author), Rasheed, Tahir (author), Shakeel, A. (author), Iqbal, Shahid (author)The genus Mimosa belongs to the Fabaceae family and comprises almost 400 species of herbs, shrubs and ornamental trees. The genus Mimosa is found all over the tropics and subtropics of Asia, Africa, South America, North America and Australia. Traditionally, this genus has been popular for the treatment of jaundice, diarrhea, fever, toothache,...review 2022

Shakeel, A. (author), Zander, F. (author), Gebert, J. (author), Chassagne, C. (author), Kirichek, Alex (author)The presence of clay-organic flocs in cohesive mud results in a complex rheological behavior of mud, including viscoelasticity, shear-thinning, thixotropy and two-step yielding. In this study, the effect of microbial degradation of organic matter on the rheological properties of mud samples, collected from different ports, was examined. The mud...journal article 2022

Kirichek, Alex (author), Shakeel, A. (author), Chassagne, C. (author), Gebert, J. (author)In some ports and waterways, hindered (delayed) settling of mud suspended in the water phase can be detected. Hindered settling phenomena are typically linked to a combination of sediment properties, suspended sediment concentration or density, hydrodynamic conditions, presence or absence of organic bridging between mud particles and the...conference paper 2022

Gebert, J. (author), van Rhees, Floris (author), Shakeel, A. (author), Kirichek, Alex (author), Habdank, Janis (author), Amman, Baerbel (author)Maintenance of the nautical depth in the seaport of Emden, Germany, is achieved by re-circulation of fluid mud using a trailing suction hopper dredger. Continued re-circulation has proven to maintain low settling rates and to keep yield stresses of re-circulated fluid mud below 50-100 Pa, in combination with densities of 1.15- 1.2 t/m³ enabling...conference paper 2022

Shakeel, A. (author), Ali, W. (author), Chassagne, C. (author), Kirichek, Alex (author)Kaolin based suspensions have wide range of applications such as slurry wall, drilling fluids, adhesives, cosmetics, refractories and pharmaceuticals, due to their abundance in nature, low cost and non-swelling nature. On the other hand, the unique properties (i.e., biodegradability) of biopolymers make them suitable candidate for variety of...journal article 2022

Zander, F. (author), Shakeel, A. (author), Kirichek, Alex (author), Chassagne, C. (author), Gebert, J. (author)Purpose<br/>Sediment organic matter (SOM) influences settling and thus the rheological behavior of suspended particles by enhancing flocculation or reducing surface charges by forming organo-mineral complexes that facilitate particle–particle interactions in consolidating sediments. It was, therefore, assumed that the microbial degradation of...journal article 2022
