Internal and external qualities of eggs deteriorate with time. This process deterioration cannot be stopped but the rate at which it occurs can reduced. The aim this study is to evaluate main effect temperature storage duration on egg quality characteristics sensory evaluation fertile non-fertile eggs. A total 600 were obtained from Lohmann Brown hen, 44 weeks age. Roosters removed hen that lai...
In developing countries, labour supply and activity choices are distorted by the existence of labour market imperfections restricting entry to the activity sectors or rationing the worked hours. The presence of decreasing returns to labour in the informal sector is another specific characteristic of labour market dualism in LDCs. Because of the existence of entry costs, hours rationing in the f...
Une femme de 66 ans a été hospitalisée pour une asthénie et une perte pondérale de 4 kg sur une période d’un mois. Son histoire médicale comprenait des infections urinaires durant l’enfance, une ostéoporose ayant entraîné de multiples fractures et un état dépressif chronique. Son traitement consistait en calcium, vitamine D, alendronate, paracétamol et benzodiazépine (flurazépam et clonazépam)....
Embedded system design is driven by strong efficiency constraints in terms of performance, silicon area and power consumption, as well as pressure on the cost and time-to-market. As of today, this forms three tough problems: 1) many-core systems are becoming mainstream, however there is still no decent approach for distributing software applications on those platforms; 2) these systems still in...
Capnophiles are bacteria stimulated by bicarbonate and CO2, the two major forms of inorganic carbon (IC) in physiological neutral liquids. Capnophiles are often pathogenic heterotrophs found in IC-rich ecological niches such as human cavities. Like capnophiles, the growth of lactic acid bacteria (LAB) such as Lactobacillus plantarum and Enterococcus faecalis is stimulated by IC. CO2 or HC are s...
We investigated the effect of fire and fire frequency on stand structure and longleaf pine (Pinus palustris P. Mill.) growth and population demography in an experimental research area in a southwest Florida sandhill community. Data were collected from replicated plots that had prescribed fire-return intervals of 1, 2, 5, or 7 years or were left unburned. Experimental treatment burns have been o...
In forests of eastern North America, introduced pathogens have caused widespread declines in a number of important tree species, including dominant species such as American beech (Fagus grandifolia Ehrh.). Most studies have focused on changes in forest composition and structure as a direct result of mortality caused by a pathogen. Our field studies of windthrow resistance in forests of northern...
Bottom trawling causes widespread disturbance of sediments in shelf seas and can have a negative impact on benthic fauna. We conducted a large-scale assessment of bottom trawl fishing of benthic fauna in different habitats, using a theoretical, size-based model that included habitat features. Species richness was estimated based on a generalized body mass versus species richness relationship. T...
Malaria control strategies aiming at reducing disease transmission intensity may impact both oocyst intensity and infection prevalence in the mosquito vector. Thus far, mathematical models failed to identify a clear relationship between Plasmodium gametocytes and their infectiousness to mosquitoes. Natural isolates of gametocytes are genetically diverse and biologically complex. Infectiousness ...
While leadership is indisputably one of the most pervasive topics in our society, the vast majority of existing research has focused on leadership as a positive force. Taking a follower-centric approach to the study of leadership, we integrate research on the Romance of Leadership and the dark side of leadership by examining followers’ perceptions of aversive leadership in the context of public...
