This study illustrates the optimisation of the experimental conditions of three sequential steps for chondroitin sulphate (CS) recovery from three cartilaginous materials of Scyliorhinus canicula by-products. Optimum conditions of temperature and pH were first obtained for alcalase proteolysis of head cartilage (58 °C/pH 8.5/0.1% (v/w)/10 h of hydrolysis). Then, similar optimal conditions were ...

The function Df , called the Bregman distance associated with f , is always well defined because ∂f(x) is nonempty and bounded, for all x ∈ X (see, e.g., [22]), so that the infimum in (1.1) cannot be −∞. It is easy to check that Df (x, y) ≥ 0 and that Df (x, x) = 0, for all x, y ∈ X. If f is strictly convex then Df (x, y) = 0 only when x = y. For t ∈ [0,∞) and z ∈ X let U(z, t) = {x ∈ X : ‖x− z...

Although it has been known since 1917 that mottled dental enamel (later recognized as dental fluorosis—DF) is identical with that observed in thyroid dysfunction, disturbances of thyroid hormone metabolism during crucial periods of tooth development as the primary cause of DF have received very little consideration by dental researchers. New findings indicate that thyroid hormone metabolism is ...

Dengue is a widespread mosquito-borne infection in human beings, which in recent years has become a major international public health concern. Symptomatic dengue virus infections can present with a wide range of clinical manifestations, from a mild febrile illness to a life-threatening shock syndrome. Both viral and host factors are thought to contribute to the manifestations of disease in each...

Fatal septicemia due to an unidentified gram-negative rod developed in a 60-year-old alcoholic. Infection due to this organism has been reported only rarely in the medical literature. Like Pasturella multocida, this organism is related to dog bites, is gram negative, and is sensitive to penicillin.

Possessors may occupy a DF position within DP, either in SPEC DP, or adjoined to NP, in line with Bresnan’s (2011) Endocentric Mapping Principles. Their default discourse function is that of ANCHOR. This accounts for phenomena such as possessor doubling, and alternative positions for possessors with different semantic and pragmatic constraints.

n this work, decision feedback (DF) detection algorithms based on multiple processing branches for multi-input multi-output (MIMO) spatial multiplexing systems are proposed. The proposed detector employs multiple cancellation branches with receive filters that are obtained from a common matrix inverse and achieves a performance close to the maximum likelihood detector (MLD). Constrained minimum...

Piglet birth weight is an important factor for their survival and growth. As the pre-mating diet influences sow's metabolic state, this may have impact on follicle development after weaning subsequent piglet weight. We investigated effect of dietary fibre (DF; sugar beet pulp (SBP) microfibrillated cellulose (MFC)) hormones metabolites (IGF-1, non-esterified fatty acids (NEFA), creatinine, urea...

A 10- to 21-d chick bioassay was conducted to determine the absolute retention value (ARV) for 2 different defluorinated phosphates (DF-1 and DF-2) and a reagent grade dicalcium phosphate (DCP). The total and test P in excreta regressed on feed P levels were subjected to general straight-line (linear), 1-slope broken-line, 2-slope broken-line, and polynomial regression methods to find the best ...

Background Currently, dengue fever/dengue hemorrhagic fever (DF/DHF) is an important public health challenge in many areas, including the Ba Tri District, Ben Tre Province, Vietnam. Methods and Aim This study was conducted in 2015 using a retrospective secondary data analysis on monthly data of DF/DHF cases and climate conditions from 2004-2014 in Ba Tri District, which aimed to explore the r...
