Background. Inulin is a storage carbohydrate found in many plants especially in chicory root, Jerusalem artichoke and dahlia tuber. It is a prebiotic with many functional properties. In earlier research concerning chemical stability of inulin, the effect of pH on rheological properties of inulin gels was mainly analysed. In these studies, the effect of time, temperature and pH on inulin chemica...
PURPOSE To evaluate whether gadoxetic acid (Gd-EOB-DTPA)-enhanced MR images of tumors taken during the hepatocyte-specific phase can aid in the differentiation between hepatocellular carcinoma (HCC) and dysplastic nodules (DNs) in patients with atypical cirrhotic nodules detected on dynamic CT images. MATERIALS AND METHODS Seventy-one patients with 112 nodules showing atypical dynamic enhance...
Common user applications cannot run in mobile ad-hoc networks (MANETs) before a method for name resolution is in place. While the Domain Name System (DNS) works well on the fixed Internet, it represents a centralized approach to name resolution, which is not suitable for MANETs. This article refines the framework developed for name resolution in MANETs and shows how a mechanism for local name r...
The Domain Name System (DNS) is a critical part of the Internet. This paper analyzes methods for passive DNS replication and describes the replication setup at the University of Auckland. Analysis of the replicated DNS traffic showed great dependency of collaborative anti-spam tools on the DNS. These tools also put a great burden on the DNS. This paper discusses analyzed anomalies in the replic...
This RFC proposes two extensions to the Domain Name System:-A specific method for entering and retrieving RRs which map between network names and numbers.-Ideas for a general method for describing mappings between arbitrary identifiers and numbers. The method for mapping between network names and addresses is a proposed standard, the ideas for a general method are experimental. This RFC assumes...
The Domain Name System (DNS) performs an essential Internet duty: the translation of host names, which are convenient for humans, into IP addresses, which are used to route packets. To do so, an application on an end-user’s system must contact a DNS resolver to perform these translations. While the user’s system may run a DNS resolver locally, many use an ISP resolver (sometimes called a DNS ca...
This memo presents operational considerations and issues with IPv6 Domain Name System (DNS), including a summary of special IPv6 addresses, documentation of known DNS implementation misbehavior, recommendations and considerations on how to perform DNS naming for service provisioning and for DNS resolver IPv6 support, considerations for DNS updates for both the forward and reverse trees, and mis...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
The crystal structure of the proton-transfer compound of 1,1'-biphenyl-4,4'-diamine (benzidine) with 3,5-dinitrosalicylic acid, viz. 1,1'-biphenyl-4,4'-diaminium bis(4'-amino-1,1'-biphenyl-4-aminium) tetrakis(2-carboxy-4,6-dinitrophenolate) ethanol disolvate, C(12)H(14)N(2)(2+)x2C(12)H(13)N(2)(+)x4C(7)H(3)N(2)O(7)(-)x2C(2)H(6)O, shows the presence of both diprotonated and monoprotonated benzidi...
