Direct Discharge

Leachates from chemical and domestic landfills are defined as hazardous wastewater. Quantitative and qualitative control of leachate can be performed by membrane separation of the total produced leachate volume. Dissolved and suspended solids in the leachate are removed from the major portion of the water phase and either returned to the landfill or further treated. The particle - free permeate meets the effluent requirements for direct discharge to virtually any watercourse. An untreated leachate flow is concentrated thirteen times by tubular type reverse osmosis. The separation efficiencies are 99% for iron, copper, chromium and zinc. For suspended solids the removal is 100%.

Recognition Errors

Three experiments were reported which investigated transfer from paired-associate (PA) learning to a recognition task (RL). Exp. I demonstrated that learning a PA list of A-B associates increased recognition errors to B words in RL (B words occurred a single time late in RL and A words occurred early in RL). It was argued that the appearance of the A words elicited the B associates implicitly, and this led to increased difficulty in identifying B words as first occurrences. An attempt to decrease RL errors to B words by interpolating unlearning activities between the A-B list and RL were unsuccessful (Exp. II). Exp. III demonstrated that the major portion of the increased errors to B words following PA learning was due to general PA-RL confusion and that specific A-B elicitations during RL added only slightly to this general confusion.

This study examines the uptake, distribution, and excretion of 31-labeled silicic acid in rat tissues at 1, 2, and 4 h after intracardiac injection of 31Si(OH)4. Plasma levels of 31Si decrease rapidly from 0.71 +/- 0.04% at 1 h to 0.07 +/- 0.06% of the dose administered per milliliter at 4 h. 31Si in plasma was found to be virtually entirely nonprotein bound. Kidney, liver, and lung accumulated the greatest amounts of 31Si per gram of wet weight, with concentrations at 4 h suggesting both relatively avid uptake and retention. Bone, skin, spleen, muscle, and testes also accumulated 31Si, but the levels were considerably lower than the aforementioned organs. Brain, however, contained negligible concentrations of 31Si throughout the study, indicating active exclusion by the blood-brain barrier. The major portion of the administered 31Si, 77 +/- 12%, was recovered in the urine within 4 h.

The Traveling Salesman Problem ◽  
Special Case

One of the first and perhaps the most well-known polynomially solvable special case of the traveling salesman problem (TSP) is the Gilmore-Gomory case (G-G TSP). Gilmore and Gomory presented an interesting patching algorithm for this case with a fairly non-trivial proof of its validity. Their work has motivated a great deal of research in the area leading to various generalisations of their results and thereby identification of fairly large polynomially solvable subclasses of the TSP. These results form a major portion of the literature on solvable cases of the TSP. In this paper, we survey the main results on solvable cases of the TSP which are direct generalisations of the G-G TSP and/or the Gilmore-Gomory patching scheme.

METABOLISM OF AROMATIC COMPOUNDS IN HEALTHY AND RUST-INFECTED PRIMARY LEAVES OF WHEAT: II. STUDIES WITH L-PHENYLALANINE-U-14C, L-TYROSINE-U-14C, AND FERULATE-U-14C

Wheat Leaves

Wheat leaves infected with stem rust, especially those of susceptible plants, contained more phenylalanine and tyrosine than healthy leaves. The utilization of phenylalanine was increased in both the susceptible and resistant reaction, but the utilization of tyrosine was increased only in the susceptible reaction. No evidence of interconversion of these amino acids was obtained.In n-butanol extracts, which contained glycosides, many constituents were labelled after feeding of L-phenylalanine-U-14C. Most of the n-butanol extractives from resistant-reacting leaves contained more label than those from susceptible-reacting leaves or from healthy leaves. However, one of the n-butanol extractives from susceptible-reacting leaves was 5–10 times as active as that isolated from the other tissues.With L-phenylalanine-U-14C and ferulate-U-14C as precursors, more activity was recovered in insoluble than in soluble esters (of ferulate and p-coumarate). With L-tyrosine-U-14C as precursor, the reverse was observed. After infection, the proportion of label in insoluble esters increased more in resistant leaves than it did in susceptible leaves, regardless of the precursor used.A major portion of the activity from these precursors was recovered in the insoluble residue that contained protein and other polymers. In the experiment with L-phenylalanine-U-14C, this residue was fractionated into protein and non-hydrolyzable material. Susceptible-reacting leaves contained equal amounts of activity in these fractions, while resistant-reacting leaves incorporated 2.5 times as much activity into the non-hydrolyzable material as into protein.

Market Town

The Air Mail route from Cairo to Baghdad is now securely established. Seven years ago the major portion of it, from Transjordan to Iraq, was no more than a project in certain far-seeing minds. The maps of this region between Amman in Transjordan and Ramadi, a little market town on the Euphrates, 65 miles west of Baghdad, were until 1921 painfully reticent. The countries of Egypt, Palestine, and to some extent Transjordan, had been fairly accurately mapped for some time, and were flown over extensively during the war by ourselves and the Germans. The landmarks are generally speaking abundant, and from the navigational point of view they therefore present no outstanding difficulties.
