The objective of this study was to evaluate the physical and chemical properties of the broiler feather concentrate (BFC) in different hydrolysis processes. The raw materials in the form of broiler feather waste (BFW) were hydrolyzed into broiler feather concentrate (BFC) products in the form of feather meal. A total of 1000 g of dry feather samples were used in this study. The study was design...

The decline in the availability of pine (Pinus taeda L.) bark (PB) supplies and increasing prices have caused concerns in the nursery industry. Research was conducted to evaluate the effect of parboiled rice (Oryza sativa L.) hulls (PBH) as a substrate amendment to PB-based container substrates on the growth of Spiraea ·bumalda L. ‘Anthony Waterer’ and to examine the changes in physical propert...

olive mill by-products could be composted and applied to olive orchard soils. these practices solve the problem of these wastes disposal and reduce the need for chemical fertilizers. therefore, the aims of this research were: (i) proposing ‘on-farm’ composting process of different olive mill waste mixtures; (ii) investigating the chemical, physical, and microbiological characteristics of produc...

this study was conducted to evaluate the effects of alfalfa hay (ah) particle size and soybean hull (sh) on physical effective fibre (pendf), particle size distribution in diets, chewing activity as well as milk composition and production in early lactating dairy cows. eight lactating holstein cows averaging 590±33 kg of bw and 47±13 days in milk were assigned in a 4×4 latin square design to a ...

Pallid breath-holding (PBH) is a childhood condition that presents with recurrent syncope. Although typically benign, severe cases can lead to asystole and anoxic seizures. Previous studies have advocated pacemaker placement to abbreviate symptoms. This was a retrospective study of patients treated with fluoxetine for PBH spells. Clinical response, side effects and avoidance of pacemaker implan...

It is well known that the convex hull of \(\{{(x,y,xy)}\}\), where (x, y) constrained to lie in a box, given by reformulation-linearization technique (RLT) constraints. Belotti et al. (Electron Notes Discrete Math 36:805–812, 2010) and Miller (SIAG/OPT Views News 22(1):1–8, 2011) showed if there are additional upper and/or lower bounds on product \(z=xy\), then can be represented adding an infi...

The amount of late decaying massive particles (e.g., gravitinos, moduli) produced in the evaporation of primordial black holes (PBHs) of mass MBH <∼ 10 9 g is calculated. Limits imposed by big-bang nucleosynthesis on the abundance of these particles are used to constrain the initial PBH mass fraction β (ratio of PBH energy density to critical energy density at formation), as: β <∼ 5× 10 (xφ/6 1...
