the objective of this research is to investigate the effect of four additives including iron slag (is), works debris (wd), fly ash (fa), and lime kiln dust (lkd) on the biochemical properties of biosolids produced at mangere wastewater treatment plant (mwwtp), auckland, new zealand. all these additives are homogenously mixed in the laboratory with biosolids at various percentages with and witho...

corn tortiilas are flat breads made from corn dough (masa) which is prepared through the nixtamalization process (alkaline cooking). corn, in nixtamalization, is cooked in a lime solution then the boiled maize is steeped in cooked liquor , following by washing out and milling to obtain wet masa flour. drying wet masa flour in air oven produce dry masa flour. cooking temperature, cooking time , ...

To create a more cost effective glass while preserving its safety, the composition of soda-lime silicate glass was modified. The amount of Silicon dioxide in the composition was decreased in order to lower the melting point of the glass, thus making the new glass more cost-effective due to lower energy consumption. Calcium oxide and sodium oxide concentrations were increased to raise chemical d...

A microcosm-based approach was used to study impacts of plant and chemical factors on the bacterial community structure of an upland acidic grassland soil. Seven perennial plant species typical of both natural, unimproved (Nardus stricta, Agrostis capillaris, Festuca ovina and F. rubra) and fertilized, improved (Holcus lanatus, Lolium perenne and Trifolium repens) grasslands were either left un...

The yield responses of sugarcane to lime and gypsum at two sites in the KwaZulu-Natal Midlands of South Africa are presented and discussed. At Dalton, on a Magwa form soil with an initial aluminium saturation index (ASI) of >80%, over a plant and four ratoon crops variety N12 gave no significant response to dolomitic lime. By contrast, variety N16 gave consistent yield responses to lime at rate...

Hawaii is the only state in the USA that grows, processes, and roasts coffee. Coffee processing, however, poses some challenges. One is the processing water, which must be treated, and should be re-used. We surveyed and collected several coffee processing water samples, both influent and effluent, from four small-scale (2-5 ha) coffee farms in Kona on Hawaii (Big Island), and from a large (1200...

Long-term improvement in behaviour of soil subjected to lime treatment depends on the mechanism its implementation. In-situ lime-treated fine-grained is often ‘kneading action’ developed by Pad-foot roller. The underlying effect kneading remains less investigated. Unconfined Compressive Strength (UCS) and microstructural modification compaction are evaluated. Kneading action undergoes better li...

In order to explain the good state of conservation and good mechanical characteristics of the lime-stabilized earth of the sugar refinery near Chichaoua (Morocco, XVIth A.C.) XRD, SEM-EDX, TG-DSC, FT-IR analyses were performed on collected samples. Moreover laboratory earth samples were prepared with selected clay minerals (presence of attapulgite) and lime, involving a reverse engineering proc...

This paper describes the design of the inductive logic programming system Lime. Instead of employing a greedy covering approach to constructing clauses, Lime employs a Bayesian heuristic to evaluate logic programs as hypotheses. The notion of a simple clause is introduced. These sets of literals may be viewed as subparts of clauses that are eeectively independent in terms of variables used. Ins...

Acid mine drainage (AMD) from abandoned coal mines continues to be one of the most significant environmental problems. Remediation of AMD requires an addition of lime source to decrease the acidity, and grouting the entire mine and encapsulating the pyrite by calcium-rich additives is often employed. Utilization of alkaline coal combustion by-products (CCBs) has gained acceptance in such remedi...
