The HyperRed-Black trees are a relaxed version of RedBlack trees accepting high degree of concurrency. In the Red-Black trees consecutive red nodes are forbidden. This restriction has been withdrawn in the Chromatic trees. They have been introduced by O. Nurmi and E. Soisalon-Soininen to work in a concurrent environment. A Chromatic tree can have big clusters of red nodes surrounded by black no...

In [6] we computed the edge Folkman number F (3, 4; 8) = 16. There we used and announced without proof that in any blue-red coloring of the edges of the graph K1 +C5 +C5 + C5 there is either a blue 3-clique or red 4-clique. In this paper we give a detailed proof of this fact.

Bribes paid by firms in Indonesia arise principally from red tape, in particular licenses, imposed by local government officials. Red tape generates direct revenues (fees) plus indirect revenues in the form of bribes. The expected value of the latter is capitalized into lower salaries needed by localities to compensate public officials. Localities in Indonesia are hampered by insufficient reven...

Background: The development of anti-red blood cell alloantibodies remains a major problem in transfusion of blood in thalassemia major patients. Also, Autoantibodies can result in clinical hemolysis and difficulty in cross-matching blood. We studied the frequency of red blood cell alloimmunization and autoimmunization among thalassemia patients who received regular transfusions in Ilam province...

Passive haemagglutination inhibition (PHI) was adapted to quantitate red cell associated IgG. Twenty one patients with autoimmune haemolytic anaemia (AIHA) had a raised red cell associated IgG, mean (SD) = 5.783 (6.183) ng/10(6) red blood cell compared with that of 69 subjects with a red cell associated IgG of 0.433 (0.349) ng/10(6) red blood cell. Thirteen of 14 blood donors with a positive di...

The etioplasts of fully dark-grown barley leaves exhibit a relatively low frequency of crystalline prolamellar bodies (ca. 16-20%). Brief red-light treatment leads to rapid disruption of all prolamellar bodies followed by a slow reformation in the subsequent dark period. When several red-light treatments are given with intervening 3-h dark periods, a marked increase in the proportion of crystal...

Loose nanofiltration (LNF) membranes can be used to treat textile wastewater if the meet stringent criteria on permeability, selectivity, and structural stability. In this work, a novel LNF membrane was developed by interfacial polymerization (IP) process between 1,3,5-tris(4-aminophenyl) benzene (TAPB) trimesoyl chloride (TMC). The structure of TAPB, which is symmetric non-planar triamine mono...

On 16 th October 2017 ex-hurricane Ophelia passed over the UK, bringing with it a unique mixture of particulates which caused sky to turn dramatic red colour.

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...

On the territory of Verkhneindigirsky Resource Reserve, located near North-Eastern border Sakha (Yakutia) Republic, distribution 16 species vascular plants listed in regional Red Book Yakutia was revealed.
