ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

THIOCYANATE ION-SELECTIVE PVC MEMBRANE ELECTRODE [PDF]
A potentiometric selective sensor based on trinuclear chromium(III) complex as a novel ionophore for the thiocyanateselective electrode is reported. The sensor displays a near Nernstian slope of 57 ± 2 mV per decade, over a wide pH range 3 - 11.

Characterization of Shewanella oneidensis MtrC: a cell-surface decaheme cytochrome involved in respiratory electron transport to extracellular electron acceptors [PDF]
MtrC is a decaheme c-type cytochrome associated with the outer cell membrane of Fe(III)-respiring species of the Shewanella genus. It is proposed to play a role in anaerobic respiration by mediating electron transfer to extracellular mineral oxides that ...

Anion Mobility Renormalization Reveals Backbone‐Dependent Tortuosity in Anion Exchange Membranes
Backbone polarity governs nanophase separation and tortuosity in anion exchange membranes (AEMs). The anion mobility across PPO‐ and PSU‐based ionomer membranes with quaternary ammonium groups depends exponentially on concentration. Extracted porosity–tortuosity ratios reveal lower tortuosity in PPO due to stronger PSU hydrophilicity.

Potentiometric characterisation of cyclodextrin inclusion complexes of local anaesthetics [PDF]
The complexation of several local anaesthetics by β and γ-cyclodextrins was studied by potentiometry with glass electrode. Tetracaine and dibucaine complexation constants were determined at 25°C in the presence of 0.1 M of NaCl.

The titrating conditions in the potentiometric titration of zinc
硫酸酸性におけるフェロシアン化カリウムによる亜鉛の定量を,さまざまな滴定条件のもとに,白金-タングステン双金属電極を用いて電位差滴定を行ない,滴定に及ぼす諸影響を検討した.20℃では硫酸濃度,硫酸アンモニウム濃度によって終点の滴定量が異なるが,滴定溶液の容積100mlあたり硫酸濃度範囲0~0.05N,硫酸アンモニウム20gで一定の滴定速度のもとに行なうと,終点までの滴定量の再現性および電位差滴定曲線がともに良好で,終点における電位差変化が大きい.亜鉛濃度0.0025~0.0125Mの溶液を,滴定誤差約+1.5%で定量することができる.60℃ではすみやかに終点に達し,硫酸濃度,硫酸アンモニウム濃度,滴定時間の影響はより小さくなるが,終点における電位差変化が小さい.滴定誤差は約-1.2%である.

Abstract Farmers' soybean [Glycine max L. (Merrill)] yields and performance were highly variable under their usual practices (without full recommended packages), indicating that current soybean production constraints likely prevent consistent results in western Oromia, Ethiopia.
