We prove existence of a competitive equilibrium in a version of a Ramsey model in which leisure enters the utility function. The analysis is carried out by means of a direct and technically simple approach that allows us to obtain detailed results concerning the behavior of equilibrium allocations and prices.

In this paper, a coupled system of differential equations involving fractional order with integral boundary conditions is discussed. the problem at hand, three main aspects that are existence, uniqueness, and stability have been investigated. Firstly, contraction mapping principle used to discuss uniqueness solutions for proposed system, secondly, existence investigated based on Leray–Schauder’...

A case of co-existent intrauterine and ectopic pregnancy is described in a patient from overseas. The difficulty in diagnosis and management is discussed, together with recent literature.

Case Report The patient first attended East Ham Chest Clinic in September 1953, when he was 68 years old. He complained of persistent cough for one year, which had been worse for the previous two months. It was associated with about an eggcupful of whitish sputum daily. He had experienced night sweats for one week, during which he complained of a pleuritic type of pain in the right chest. There...

Ontologies have primarily been promoted to facilitate interagent communication and knowledge reuse. There has not been as much emphasis on using ontologies to improve system quality. As a result, typically, ontology development, and verification and validation are treated as different stages in the life cycle. However, this paper argues that ontology design should include emergent knowledge tha...

Anyone who has resided in a rural area for any length of time realizes that there are existent in both folklore and media a substantial number of myths about the tranquility of "rural existence." This paper examines a few of the common myths of "rural existence" and compares them to some of the documented realities of rural living. The thesis of the paper is that such a comparison should explod...

Electronic archives are increasingly being used to store information that needs to be available for a long time such as land register information and medical records. In order for the data in such archives to remain useful, their integrity and authenticity must be protected over their entire life span. Also, in many cases it must be possible to prove that the data existed at a certain point in ...
