Algebraic effects and handlers are a promising technique for incorporating composable computational into functional programming languages. Effect enable concisely with different effects, but they do not offer convenient way to program instances of the same effect. As solution this inconvenience, previous studies have introduced _named effect handlers_, which allow programmer distinguish among i...
A cross-sectional study was conducted from 10 January to 9 April 2012, to determine the seroprevalence of tuberculosis (TB) of all captive Asian elephants and their handlers in six locations in Peninsular Malaysia. In addition, trunk-wash samples were examined for tubercle bacillus by culture and polymerase chain reaction (PCR). For 63 elephants and 149 elephant handlers, TB seroprevalence was ...
Background: With an estimated 600 million cases of foodborne illnesses annually, unsafe food is a threat to human health and economies globally. World Health Organization (WHO) emphasizes that the future safety transform knowledge into action for people communities. Hence, this study was undertaken evaluate effectiveness educational intervention package on Knowledge, Attitude Practice (KAP) han...
OBJECTIVES Heavy lifting is associated with musculoskeletal disorders but it is unclear whether it is related to acute reversible effects or to chronic effects from cumulated exposure. The aim of this study was to examine whether musculoskeletal symptoms in Danish airport baggage handlers were associated with their seniority as baggage handler, indicating chronic effects from cumulated workload...
As popularity of algebraic effects and handlers increases, so does a demand for their efficient execution. Eff, an ML-like language with native support for handlers, has a subtyping-based effect system on which an effect-aware optimizing compiler could be built. Unfortunately, in our experience, implementing optimizations for Eff is overly error-prone because its core language is implicitly-typ...
Eff is a programming language based on the algebraic approach to computational effects, in which effects are viewed as algebraic operations and effect handlers as homomorphisms from free algebras. Eff supports first-class effects and handlers through which we may easily define new computational effects, seamlessly combine existing ones, and handle them in novel ways. We give a denotational sema...
BACKGROUND Parasitic intestinal infections are still among socioeconomic problems in the world, especially in developing countries like Iran. Food-handlers that directly deal with production and distribution of foods between societies are one of the most important sources to transmit parasitic infections to humans. The aim of this study was to determine the prevalence of intestinal parasitic in...
