Upon performing colorimetric determination of chromium with diphenylcarbazide (DPC), the following were found. The color development proceeded not only in dilute sulphuric acid solution, but also in solutions of HNO3, HCl, HC1O4 and CH3COOH or in mixed solutions of these acids. Wide concentration ranges (about 0.01-0.5 N) of these single acids allowed perfect development of the Cr6+ coloration ...

PURPOSE Recent studies examining depression disease management report improvements in short-term outcomes, but less is known about whether improvements are sustainable over time. This study evaluated the sustained clinical effectiveness of low-intensity depression disease management in chronically depressed patients. METHODS The Depression in Primary Care (DPC) intervention was introduced in ...

BACKGROUND Glomerulosclerosis and interstitial fibrosis, which are cardinal features of the end-stage kidney, result from accumulation of extracellular matrix proteins, particularly collagen, in the glomerular mesangium and renal interstitium. This study examined the effect of D-penicillamine (DPC), which inhibits collagen deposition, on disease progression in the remnant kidney. METHODS Two ...

OBJECTIVE To compare superficial surgical site infection (SSI) rates between delayed primary wound closure (DPC) and primary wound closure (PC) for complicated appendicitis. BACKGROUND SSI is common in appendectomy for complicated appendicitis. DPC is preferentially used over PC, but its efficacy is still controversial. METHODS A multicenter randomized controlled trial was conducted in 6 ho...

Female mice generating oocytes lacking complex N- and O-glycans (double mutants (DM)) produce only one small litter before undergoing premature ovarian failure (POF) by 3 months. Here we investigate the basis of the small litter by evaluating ovulation rate and embryo development in DM (Mgat1(F/F)C1galt1(F/F):ZP3Cre) and Control (Mgat1(F/F)C1galt1(F/F)) females. Surprisingly, DM ovulation rate ...

Abstract Recently the density peaks clustering algorithm (DPC) has received a lot of attention from researchers. The DPC is able to find cluster centers and complete tasks quickly. It also suitable for different kinds tasks. However, deciding cutoff distance $${d}_{c}$$ d c </mml:m...

Starting from the principle of instantaneous power theory, this article explores various direct control (DPC) strategies for three-phase two-level pulsewidth modulation (PWM) converters. After summarizing fundamental formula PWM rectifiers, studies operating conventional table-based approach and its related improvements. It further looks into advanced counterparts employing space vector differe...

Shaham et al. (1) reported that the white blood cells (WBC*) of 12 anatomists and pathologists exposed to formaldehyde (FA) in a laboratory had significantly higher average levels of DNA—protein cross-links (DPC) than those of eight subjects 'who had never been exposed to FA'. Means and coefficients of variation (CV) (%SD) for DPC/total DNA were 0.288 (19%) for the exposed group and 0.227 (30%)...

In powder die compaction, the characteristics of the end product are dictated by the mechanical properties of the powder being processed. A commonly used constitutive model describing the behavior of pharmaceutical powders during compaction is the modifi ed-Drucker Prager Cap (DPC) model. The experiments used to measure DPC parameters are time consuming and, hence, limit the model’s wide-spread...
