An evaluation of a modified product size distribution model based on t-family curves for three different crushers
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2013)
Crushing is a process which is widely used in mineral processing plants, cement factories, aggregates plants and some other industrial plants. Specific fracture energy of the particles is not the only fundamental property ...
Synthesis of a bipyridine-derived achiral thiourea trifluoromethanesulfonic acid salt and its application as an additive in organocatalytic asymmetric reactions
(2013)
The host-guest complex of a proline-thiourea bipyridine trifluoromethanesulfonic acid salt can catalyze organocatalytic asymmetric reactions such as aldol, Michael, and Mannich in polar protic medium with high stereoselectivities. ...
Seasonal variation and occurrence of algal turf community in Lake Ladik, Turkey
(2013)
The composition and seasonal variation of the algal turf of Lake Ladik were studied using samples collected from one station between June 2000 and May 2001. 50 tax^jfJriatoms were identified in the epiphyton. Navicula ...
Effects of mill speed on kinetic breakage parameters of four different particulate pumices
(Taylor and Francis, 2013)
In this study, the effect of mill speed was investigated on different particulate pumice samples at batch grinding conditions based on a kinetic model. For this purpose, S i and B i,j equations were determined from the ...
The effect of social support on state anxiety levels during pregnancy
(Scientific Journal Publishers Limited, 2013)
In this study our aim was to determine the effect of pregnant women's perception of level of multidimensional social support during pregnancy on their state anxiety level. The sample comprised 160 pregnant women who were ...
Frequency and etiology of chondrodermatitis nodularis chronica helicis
(2013)
Objectives: Chondrodermatitis nodularis chronica helicis (CNH) is a painful nodule affecting the pinna. The etiology of the disease is unknown. We devised to show a correlation between CNH and systemic health problems of ...
Blocking of L-type calcium channels protects hippocampal and nigral neurons against iron neurotoxicity: The role of L-type calcium channels in iron-induced neurotoxicity
(Informa Healthcare, 2013)
Iron plays an important role in maintaining normal brain function. However, iron overload and enhanced hydroxyl radical formation have been implicated as the causative factors of some neurodegenerative disorders such as ...
N-O tethered carbenoid cyclopropanation facilitates the synthesis of a functionalized cyclopropyl-fused pyrrolidine
(2013)
We report a facile approach to a cyclopropyl-fused pyrrolidine, which contains four stereogenic centers, by employing the N-O tethered carbenoid methodology. The synthesis was facilitated by the development of a direct ...
Electrochemical approach for the sensitive determination of anticancer drug epirubicin in pharmaceuticals in the presence of anionic surfactant
(Editions de l'Academie Republique Populaire, 2013)
In this research, sensitive, rapid, different electrochemical methods were developed for the determination of anticancer drug epirubicin. The aim of the study was to fully validated determination of epirubicin in ...
Validated electroanalytical and RP-LC assay of ertapenem in its pharmaceutical dosage form
(Editions de l'Academie Republique Populaire, 2013)
Ertapenem is a member of carbapenem group beta-lactam antibiotics. The electrochemical behavior of ertapenem at the surface on a boron-doped diamond electrode is described. It is investigated and determined using cyclic, ...
