Plant growth promoting substances are widely used in modern agriculture. Several products in the market are humic substances isolated from different sources. The filter cake, a residue of sugar production, is a rich and renewable source of organic matter and these characteristics place the filter cake as a possible source of plant growth promoting substances. Humic acids (HA) from filter cake w...

cottonseed is considered among most important crops. it contains about 26 percent oil that ‎in used for vegetable oil production. after oil extraction, the remaining part of the seed know as ‎cottonseed cake with 45 percent protein is routinely used as a protein supplement in feed ‎rations for livestock and less for food use due to presence of gossypol, a toxic constituent of ‎cottonseed.‎ in t...

the scope for using sunflower cake in ration formulation was tested in 6 horses employed for equine tourism. three experimental diets providing the same amount of proteins and energy as the control diet were formulated using rising doses of sunflower cake (sd3: 0.3 kg; sd6: 0.6 kg and sd10: 1.0 kg). digestibility evaluation using internal markers showed that rising sunflower cake doses reduced ...

We wish to consider the following type of cake division problem: There are p individuals. Each individual has available a measure that he or she uses to evaluate the sizes of pieces of cake. We wish to partition our cake into q pieces in such a way that the various evaluations that the individuals make of the sizes of the pieces satisfy certain pre-assigned equalities and inequalities. Our main...

Enzymatic hydrolysis ofxylan, and isolation ofhydrolysis products. Cotton-seed cake, lOOOg of air-dried matter (containing 458g of total pentose analyzed by the orcinol-HCl method),1) was soaked in 600 ml of2% NaOH solution at room temperature for 4 days, to promote the enzymatic susceptibility of xylan in the cake. The alkali-treated cake (790g of air-dried matter containing 394g of total pent...

We propose an online form of the cake cutting problem. This models situations where players arrive and depart during the process of dividing a resource. We show that well known fair division procedures like cut-and-choose and the Dubins-Spanier moving knife procedure can be adapted to apply to such online problems. We propose some desirable properties that online cake cutting procedures might p...

We introduce the simultaneous model for cake cutting (the fair allocation of a divisible good), in which agents simultaneously send messages containing a sketch of their preferences over the cake. We show that this model enables the computation of divisions that satisfy proportionality — a popular fairness notion — using a protocol that circumvents a standard lower bound via parallel informatio...

The use of biological phosphorus removal by activated sludge has been shown to have adverse effects downstream in the solids handling processes of anaerobic digestion. From struvite formation problems within the digesters to increased polymer dosage and dewatered biosolids solids content. The fundamental cause is unknown however phosphorus removal prior to anaerobic digestion has been shown to ...

Jatropha curcas belongs to the family Euphorbiaceae and is distributed in many tropical and subtropical countries. The toxicity of the whole seed Jatropha curcas has been known for a long time. Jatropha plant is used as a source of biodiesel. In addition to being a source of oil, Jatropha also provides seed-cake and is a by-product of oil extraction that serves as a highly nutritious and econom...

The relationship between the pore liquid pressure (pL) and the cake compressive stress (ps) is required in analyzing cake ltration. This relationship (for the one-dimensional case) is commonly assumed to be dpL+dps =0 although similar but di#erent ones may also be advanced from the multiphase 9ow theory. The e#ect of these di#erent expressions is studied by examining the correspondence between ...
