The enantioselectivity of HPLC chiral stationary phases produced with human serum albumin (HSA) fragments was investigated. An HSA fragment (HSA-FG75) was isolated by size-exclusion chromatography following peptic digestion of HSA. The isolated HSA-FG75 was mainly an N-terminal half peptide with an average molecular weight of about 35,000 daltons. The HSA and HSA-FG75 proteins were bound to ami...

Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...

Laboratory scale studies have repeatedly reported high P-retention in slag, a by-product of the steel manufacturing industry. Thus, it has emerged as a potential material to increase P-removal from constructed wetlands (CWs). However, several limitations were highlighted by field experiments, including the high pH of treated water and clogging. We hypothesized that the addition of sedimentary r...

INTRODUCTION Complex fracture dislocations of the midfoot are uncommon. Improved outcomes have been demonstrated where it has been possible to restore and maintain the length and alignment of the medial column as well as the congruity of the articular surfaces. We present our experience with the use of angle-stable locking plates in the stabilisation of complex midfoot fracture dislocations. ...

conclusions experimental results showed that mcns is an excellent sorbent for removal of mercury ions from petrochemical waste water. in addition, highly complex matrix of this waste does not affect the adsorption capability of mcns. results an effective hg (ii) removal (99.8%) was obtained at ph 6, with 50 mg of mcns for an initial concentration of this ion in petrochemical waste water (5.63 m...

background: surface water and groundwater pollution with various forms of nitrogen such as ammonium and nitrate ions is one of the main environmental risks. the major objectives of this study were to evaluate the capacity of natural zeolite (clinoptilolite) to remove no3- and nh4+ from polluted water under both batch and column conditions. methods: the laboratory batch and column experiments we...

We prove a q-analogue of the row and column removal theorems for homomorphisms between Specht modules proved by Fayers and the first author [16]. These results can be considered as complements to James and Donkin’s row and column removal theorems for decomposition numbers of the symmetric and general linear groups. In this paper we consider homomorphisms between the Specht modules of the Hecke ...

MAGEE. T. V., and D. F. ZINKEL. 1986. A rapid method for diterpene resin acid analysis of pine needle oleoresin. Can. J. For. Res. 16: 1107-1109. A method for diterpene resin acid analysis has been developed for pine oleoresin samples at the submilligram level. The method utilizes the removal of acidic components by a micro-DEAE-Sephadex ion-exchange column and analysis of the recovered resin a...
