Calcium metabolism (Ca) in layers depends on many factors which can be divided into factors influencing the intake, absorption, retention and/or excretion of Ca. Varying of any of above mentioned factors presented and reviewed in this study, exhibit their impact on quality of bones in layers and egg shell quality. For the purpose of maintaining of the egg quality and quality of layer hens’ bone...

A two-level overlapping domain decomposition method is analyzed for a Nédélec spectral element approximation of a model problem appearing in the solution of Maxwell’s equations. The overlap between subdomains can consist of entire spectral elements or rectangular subsets of spectral elements. For fixed relative overlap and overlap made from entire elements, the condition number of the method is...

Abstract. This paper proposes admittance matrix models to approach the behavior of six modern multiport functional blocks called: differential difference amplifier, differential difference operational floating amplifier, differential difference operational mirror amplifier, differential difference current conveyor, current backward transconductance amplifier and current differencing transconduc...

Exposure to flour dust can be found in the food industry and animal feed production. It may result in various adverse health outcomes from conjunctivitis to baker's asthma. In this paper, flour dust exposure in the above-mentioned occupational environments is characterized and its health effects are discussed. A peer-reviewed literature search was carried out and all available published materia...

Conventional transportation and electricity industries are considered as two major sources of greenhouse gases (GHGs) emission. Improvement of vehicle’s operational efficiency can be a partial solution but it is necessary to employ Plug-In Hybrid Electric Vehicles (PHEVs) and Renewable Energy Sources (RESs) in the network to slow the increasing rate of the GHGs emission. However, it is crucial ...

Kol, Bhil and Gond are some of the ancient tribal populations known from the Ramayana, one of the Great epics of India. Though there have been studies about their affinity based on classical and haploid genetic markers, the molecular insights of their relationship with other tribal and caste populations of extant India is expected to give more clarity about the the question of continuity vs. di...

the main tasks of ‘environmental graphics’ have been designated as: provision of instructions and essential information, environmental embellishment, ease of interconnection and visual identity establishment all of which can affect the culture and identity of the audience through an unconscious process. if we consider, on the one hand, the crisis of identity and cultural problems of the present...
