MECHANISM OF HOT ALKALINE REFINING OF PULP

Soft Sensors for Pulp Freeness and Outlet Consistency Estimation in the Alkaline Peroxide Mechanical Pulping (APMP) High-Consistency Refining Process

In the mechanical pulping process, some process state and product quality variables are difficult to measure on-line. In this paper, soft sensors were used to estimate Canadian Standard Freeness (CSF) and outlet consistency (Cout) after the high consistency refining stage of the alkaline peroxide mechanical pulping (APMP) process. After the secondary variables for modeling that are readily avai...

Properties of alkaline phosphatase of the human dental pulp.

Enzymatic and immunological properties of alkaline phosphatase [ALP; orthophosphoric monoester phosphohydrolase, alkaline optimum, EC 3.1.3.1.] in the human dental pulp were investigated. In inhibition and thermal inactivation studies, dental pulp ALP showed properties of universal-type ALP (kidney/bone/liver type). Dental pulp ALP cross-reacted with polyclonal and monoclonal antibodies against...

Structure and mechanism of alkaline phosphatase.

Alkaline phosphatase was the first zinc enzyme to be discovered in which three closely spaced metal ions (two Zn ions and one Mg ion) are present at the active center. Zn ions at all three sites also produce a maximally active enzyme. These metal ions have center-to-center distances of 3.9 A (Zn1-Zn2), 4.9 A (Zn2-Mg3), and 7.1 A (Zn1-Mg3). Despite the close packing of these metal centers, only ...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
