I estimate Modified-Dynamics (MOND), median M/L values for recently published catalogues of galaxy groups. While the median, Newtonian M/L values quoted for these catalogues are (110 − 200)h75(M/L) , the corresponding values for MOND are less than 10 (M/L) (where the mass includes contributions from galactic, and intra-group gas). Subject headings: Galaxies: kinematics and dynamics; Cosmology: ...

The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method. Miduk copper concentrator is located in Kerman Province, Iran, and its size reduction stage includes one gyratory crusher which feeds one SAG mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). After SAG mill, a tromm...

MAC striping has been suggested as a technique to authenticate encrypted payloads using short tags. For an idealized MAC scheme, the probability of a selective forgery has been estimated as ( `+m m )−1 ·2−m, when utilizing MAC striping with `-bit payloads and m-bit tags. We show that this estimate is too optimistic. For m ≤ ` and any payload, we achieve a selective forgery with probability ≥ ( ...

Fresh water supply and its security encounter a high level of fluctuating variability under global climate changes. To address these concerns in catchment water management, a good understanding of land use/cover impacts on the hydrological cycle affecting water supply is crucial. The objective of this study is to define a model to investigate the impact of existing land use/cover on water yield...

We prove the estimate l-asdimπ1(M) ≤ 7 for the linearly controlled asymptotic dimension of the fundamental group of any 3dimensional graph-manifold M . As applications we obtain that the universal cover f M of M is an absolute Lipschitz retract and it admits a quasisymmetric embedding into the product of 8 metric trees.

[1] Estimates of the oceanic lateral eddy diffusion coefficient Aredi vary by more than an order of magnitude, ranging from less than a few hundred m/s to thousands of m/s. This uncertainty has first-order implications for the intensity of oceanic hypoxia, which is poorly simulated by the current generation of Earth System Models. Using satellite-based estimate of oxygen consumption in hypoxic ...
