| Constructs for expressing exception handling can greatly help to avoid clutter in code by allowing the programmer to separate the code to handle unusual situations from the code for the normal case. Handling exceptions in functional languages has received less attention mainly due to the inherent connict between the control ow oriented approach of exception handlers and the functional style o...

This study aimed to determine the levels of sodium cyclamate in candied fruit and analyze relationship between knowledge behavior food handlers Household Food Industry (IPRT). research method is descriptive-analytic using a cross-sectional design. The location was Jambi City, samples were tested Baiturahim STIKes Mathematics Natural Sciences laboratory involving 50 selections for examining cont...

Food handlers with improper personal hygiene practices have a significant role in transmitting foodborne parasites, including intestinal protozoa. The current systematic review and meta-analysis aimed to evaluate the global prevalence of protozoan parasites among food handlers. Multiple databases (PubMed, Scopus, Pro-Quest, Web Science, Science Direct, Google Scholar) were explored for relevant...

The contamination of the surface water lagoons is a common problem in developing countries, and can affect fishing activities. A case study was conducted on quality microbiological marketing chain Peruvian Amazon (Laguna de Yarinacocha). microbiological, physical–chemical parasitological parameters were evaluated three points lagoon near landing stage; facilities, handlers species fish (Prochil...

Usually complex systems are controlled by an operator co-operating with a computer-based controller. The controlling software runs in continuous interaction with the operator and constantly reacts on operator’s interruptions by dynamically adapting system behaviour. Simultaneously it catches the exceptions signalling about errors in the system components and performs error recovery. Since inter...

Aim this study was to determine the prevalence of brucellosis in various occupations in Northern State, Sudan, during 2012. A total of 753 serum samples (from 21 veterinarian, 39 meat inspectors, 407 abattoir workers and 286 animal handlers) in different localities were collected and screened for brucella antibodies by using Rose Bengal Plate Test (RBPT), Serum Agglutination Test (SAT) and 2 Me...

Within a classical call-by-name λ -calculus, we prove, using Krivine’s realizability, that all terms typable with disjunctive normal forms (disjunctions of conjunctions of literals) share a common computational behaviour: they implement a multi-exception handling mechanism whose exact geometry depends on the tautology. By using dynamic binding, we are able to define equivalent and more efficien...

Recent work has provided delimited control for Prolog to dynamically manipulate the program control-flow, and to implement a wide range of control-flow and dataflow effects on top of. Unfortunately, delimited control is a rather primitive language feature that is not easy to use. As a remedy, this work introduces algebraic effect handlers for Prolog, as a high-level and structured way of defini...

Modern virtualized service infrastructures expose attack vectors that enable attacks of high severity, such as attacks targeting hypervisors. A malicious user of a guest VM (virtual machine) may execute an attack against the underlying hypervisor via hypercalls, which are software traps from a kernel of a fully or partially paravirtualized guest VM to the hypervisor. The exploitation of a vulne...

Bovine tuberculosis (BTB) is widespread but poorly controlled in Africa and M. bovis is posing threats to human health. The risk of cattle handlers to M. bovis prevalence and public health significance of BTB in Cameroon were assessed. Slaughter inspection records from major cities revealed that BTB detection rates in cattle from 0.18% to 4.25% and BTB lesions were most common. Analyses of tiss...
