Giardiosis is one of the most frequent parasites of dogs and cats. Since several years, the treatment is based on the use of metronidazole. A coproscopic study in four dog kennels was conducted to demonstrate, at a significant level, the efficacy of oxfendazole (Dolthène, Merial). At the posology of 11.3 mg/kg each day during three days (D1, D2 and D3), no dogs eliminated Giardia cysts and all ...

Food influences the health of a population to a great degree, therefore, the control of food quality is an important government activity, and is legislatively regulated. Raw food materials quality is a complex term that includes nutritional, sensory, hygienictoxicological, and technological points of view. Food has to fulfill all quality requirements, but above all, it has to be safe. High qual...

Hygienic behaviour performed by middle!aged worker bees is an important intranidal task in colonies of the honey bee Apis mellifera "L[#[ It comprises detecting diseased brood in the larval and pupal stages and removing all such infected brood\ thereby decreasing the incidence of infection[ Hygienic behaviour consists of two task!components] uncapping cells and removing the cell contents[ The a...

BACKGROUND Despite the increasing promotion of alcohol-based hand rubs and the worldwide use of ethanol-based hand rubs in hospitals only few studies have specifically addressed the issue of ethanol absorption when repeatedly applied to human skin. The aim of this study was to assess if ethanol absorption occurs during hygienic and surgical hand disinfection using three different alcohol-based ...

It is possible to define a formal semantics for configuration, elaboration, linking, and evaluation of fully-parameterized first-class modules with hygienic macros, independent compilation, and code sharing. This dissertation defines such a semantics making use of explicit substitution to formalize hygienic expansion and linking. In the module system, interfaces define the static semantics of m...

Survey of sanitation conditions by qualitative sanitation measurement were carried out in three districts, Chachoengsao Province, Thailand. The sanitation of each household was assessed in terms of positive stool examination and scores of seven main sanitary activities which were used to classify each household's sanitation as hygienic or non-hygienic. Stool collections were made from each hous...

The study aims to increase community awareness at the household level about certain hygienic practices and water quality in order to develop an effective program that will target improving specific hygiene-related behavior. The study was carried out in two Palestinian villages and applies a quasi-experimental design where chemical and biological water quality analysis as well as residential beh...

This paper gives an assessment of hygienic conditions found in 22 primary and 12 secondary schools in the city of Split during the school year 1990/91. The data were compared with the results of a similar investigation carried out in eight primary schools in the neighbouring Sinj area. The assessment consisted of the examination of the facilities, questionnaires, and microbiological analysis of...

ACL2 is a theorem prover for a purely functional subset of Common Lisp. It inherits Common Lisp’s unhygienic macros, which are used pervasively to eliminate repeated syntactic patterns. The lack of hygiene means that macros do not automatically protect their producers or consumers from accidental variable capture. This paper demonstrates how this lack of hygiene interferes with theorem proving....

Over the past two decades, Scheme macros have evolved into a powerful API for the compiler front-end. Like Lisp macros, their predecessors, Scheme macros expand source programs into a small core language; unlike Lisp systems, Scheme macro expanders preserve lexical scoping, and advanced Scheme macro systems handle other important properties such as source location. Using such macros, Scheme pro...
