CMC polymer is used as an additive to decrease water loss and mud-cake-thickness in mud drilling. In this study, the effect of CMC and CMC nanoparticles on water loss and mud-cake-thickness in mud drilling is investigated. CMC nanoparticles are made by using of ball milling and their size is measured by Particle size analyzer. CMC and CMC nanoparticles which were prepared by Hamilton batch mixe...
The article presents the results of field research to determine physical and chemical composition sediments in Langar Kalkama reservoirs Kashkadarya region. Data on volume floods Langar, Kyzylsuv, Kalkama, Dehkanabad flood 2015-2021 were presented, it was noted that 2019, there 3 times more than 2015. granulometric content turbid middle part reservoir is 29.93% from 0.005-0.002 mm, 21.36% 0.01-...
This paper reports the preparation of sulphur polymer cements (SPCs) incorporating waste ilmenite mud for use in concrete construction works. The ilmenite mud raw material and the mud-containing SPCs (IMC-SPCs) were characterised physico-chemically and radiologically. The optimal IMC-SPC mixture had a sulphur/mud ratio (w/w) of 1.05 (mud dose 20 wt%); this cement showed the greatest compressive...
This work investigates the impact of mud from a zinc-plating plant and zeolite saturated with zinc on early hydration processes of ordinary Portland cement. During the first 48 hours of hydration, the addition of mud significantly affects the cement hydration kinetics. The partial replacement of cement with zeolite saturated with zinc ions, reduces the negative impact of mud on the hydration pr...
Goals include the development of models and methods that explain observed material and acoustic properties of different physical types of shallow-ocean mud sediments. Other goals are to assess prior data relating to the acoustic properties of mud and to provide guidance in the development and interpretation of experiments. A related goal is to construct models that will guide inversion techniqu...
Purpose To compare the outcome of patients with Hodgkin lymphoma who received post-transplantation cyclophosphamide-based haploidentical (HAPLO) allogeneic hematopoietic cell transplantation with the outcome of patients who received conventional HLA-matched sibling donor (SIB) and HLA-matched unrelated donor (MUD). Patients and Methods We retrospectively evaluated 709 adult patients with Hodgki...
BACKGROUND The unique, black, hypersaline mud mined from the Dead Sea shores is extensively used in mud packs, masks, and topical body and facial treatments in spas surrounding the lake, and in cosmetic preparations marketed worldwide, but little is known about its antimicrobiological properties. METHODS We performed detailed microbial and chemical analysis of Dead Sea mineral mud compounded ...
Tetrabromobisphenol A (TBBPA) and hexabromocyclododecanes (HBCDs) were analyzed in 12 tissues of prey (mud carp) and predator (northern snakehead) fish from an e-waste area, South China. The TBBPA concentrations in different tissues ranged from 0.03 to 2.85 ng/g wet weight (ww) in mud carp and 0.04 to 1.30 ng/g ww in northern snakehead. The concentrations of HBCDs ranged from 0.07 to 96.9 ng/g ...
The theory of Multiuser Detection (MUD) for DS-CDMA is studied. A brief description of optimal MUD is given and some low complexity sub optimal implementations are described. This is followed by a short note on Blind Multiuser detection. Conclusions are drawn from theoretical and simulation results. Towards the end, a new low complexity scheme for MUD in DS-CMDA is proposed. Simulation results ...
There is a lot of mud on the moors. Thankfully this does not mean that my boots need cleaning after every walk. If the weather has been dry or there is a light drizzle, then my boots are covered by a thin film of peaty dust which I can live with. If it is very wet then the water cascades down the paths and my boots return sodden but with only the odd stem of grass or heather stuck to them. All ...
