since treatment of landfill leachate is quite complicated, there is a need to develop a system thatis capable of providing high treatment efficiencies. in this study, the treatment performance of a jet - loopmembrane bioreactor (jlmb) operated at different organic loading rates was investigated by observing thechanges in chemical oxygen demand (cod), total kjehldahl nitrogen (tkn) and total amm...

poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. the aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (pmeca) particles containing 5-aminosalicylic acid (5-asa). pmeca particles were prepared using the inverse emulsification...

this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

in investigation of dynamic specifications of castellated beams, it is necessary to be studied the excitation intensity of dynamic mode shapes for different loading conditions. it is evident that for a specific loading, not all modes of a structure are excited and the structural response depends on the applied loading specifications. in this paper using the finite element method (based on ansys...

The following problem arose in the planning of optical communications networks which use bidirectional SONET rings. Traac demands d i;j are given for each pair of nodes in an n-node ring; each demand must be routed one of the two possible ways around the ring. The object is to minimize the maximum load on the cycle, where the load of an edge is the sum of the demands routed through that edge. W...

Definition 1.1. A database schema is a small category C, and a morphism of schemas from C to C′ is a functor F : C → C′. An object c of C is called a type or a table in C, and an arrow f : c→ c′ is called a column of c valued in c′. A database state on schema C is a functor δ : C → Set. Given an object c ∈ Ob(C), an element x ∈ δ(c) is called a c-representative in δ, or a row of δ(c). We refer ...

definition Definition. The class of all bands is defined by a class-wrapped membership rule. In[2]:= class@t_, member@x_, BANDSDD := ReleaseHold@Module@8u = Unique@D<, class@t, and@member@x, HoldPattern@SEMIGPSDD, forall@u, implies@member@u, fix@domain@xDDD, member@pair@pair@u, uD, uD, xDDDDDDD The DownValues of class need to be sorted to put this rule ahead of the default class rule. In[3]:= D...

Acetabular fractures are produced by high energy injuries that often cause dislocation of the fragments with gaps and steps (Olson et al., 1997). The goal of operative treatment of such fractures is to restore acetabular anatomy with perfect fragment reduction and stable fixation in order to enable early joint movement (Letournel and Judet, 1993). The fixation of the fragments is not strong eno...
