Bipolar-valued fuzzification of the notion of implicative hyper BCK-ideals is considered. Using the concepts of positive and negative lever sets, a characterization of a bipolar fuzzy implicative hyper BCK-ideal is provided. A relation between a bipolar fuzzy hyper BCK-ideal and a bipolar fuzzy implicative hyper BCK-ideal is established. A condition for a bipolar fuzzy hyper BCK-ideal to be a b...

In this paper we introduce the concepts of hyper P -semisimple Ialgebra and Abelian hyper I-algebra and we state and prove some related results. The hyper p-semi simple I-algebras is a generalization of p-semisimple BCI-algebras and a subclass of hyper I-algebras. Specially we show that every Abelian hyper I-algebra is a hyper psemisimple I-algebra and a commutative canonical hypergroup. In fol...

The values given in the literature for the ammonia content of the brain show wide variation (l-3). Most of these values are of doubtful reliability, since the methods of estimation have not generally taken into account the presence of labile acid amides such as glutamine, which are now known to occur in the brain and which easily liberate ammonia on treatment with alkalies under the conditions ...

We report laboratory experiments and modeling calculations investigating the effect of a hydrocarbon coating on ammonia ice spectral signatures. Observational evidence and thermochemical models indicate an abundance of ammonia ice clouds in Jupiter’s atmosphere. However, spectrally identifiable ammonia ice clouds are found covering less than 1% of Jupiter’s atmosphere, notably in areas of stron...

We present a simple explicit construction of hyper-Kähler and hyper-symplectic (also known as neutral hyper-Kähler or hyper-parakähler) metrics in 4D using the Bianchi type groups of class A. The construction underlies a correspondence between hyper-Kähler and hyper-symplectic structures in dimension four.

odor emission is a common environmental problem in septic tank. the feasibility of using trickling filter to eliminate the malodorous gases from the septic tank was studied. a trickling filter is set up at the outlet of the waste gases of the septic tank, which was attached to the university's cafeteria. in this investigation, the trickling filter system was used, measuring the hydrogen sulfide...

rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. produced hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of methane by methanogenesis. nutritionists have tried to find ways to decrease loss and energy and...

‎Let G=(V(G),E(G)) be a simple connected graph with vertex set V(G) and edge‎ ‎set E(G)‎. ‎The (first) edge-hyper Wiener index of the graph G is defined as‎: ‎$$WW_{e}(G)=sum_{{f,g}subseteq E(G)}(d_{e}(f,g|G)+d_{e}^{2}(f,g|G))=frac{1}{2}sum_{fin E(G)}(d_{e}(f|G)+d^{2}_{e}(f|G)),$$‎ ‎where de(f,g|G) denotes the distance between the edges f=xy and g=uv in E(G) and de(f|G)=∑g€(G)de(f,g|G). ‎In thi...

The role of the gastrointestinal tract as a major source of blood ammonia has been extensively studied in animals and in patients with liver disease. Less information is available concerning the relative contribution to the blood ammonia by other organs, such as muscle, liver, brain and kidney, which are known to be concerned with ammonia metabolism (1). The renal release of ammonia into the sy...

The kidney consistently releases ammonia into the renal venous circulation of normal subjects and patients with compensated liver disease (1-4). Under conditions of normal acid-base balance, the quantity released usually approximates the amount of ammonia excreted into urine (3, 4). From determinations of arteriovenous ammonia differences across various organs, it has become apparent that the r...
