The incidence of intractable age-related neurodegenerative conditions such as Alzheimer's and Parkinson's diseases and age-related macular degeneration is projected to increase substantially over the coming decades with the ageing of the global population. While the burden of disease associated with other chronic conditions has decreased in recent times due to improved diagnosis and treatment, current therapies for neurodegenerative diseases still fall short in that they are only effective in treating signs and symptoms – they do little to slow or prevent disease progress. Thus, there is an urgent need for treatments that address disease progression.

The behavior to hydrogen damage caused by corrosion in a H2S medium is studied in a molded ferrite- austenite (52-48 %) duplex stainless steel 22Cr5NiMoN type (UNS-J9.22.05) under both, static (damaging mechanism called Hydrogen Induced Cracking (HIC)) and sustained load (damaging mechanism called Sulfide Stress Cracking (SSC)), conditions.

Behavior to hydrogen damage caused by stress corrosion in a H2S medium (SSC) and to intergranular corrosion (IGC) in different mediums, such as oxalic acid (C2H2O4-2H20), iron sulphate-50 % sulfuric acid [Fe2(SO4)3-50 % H2SO4], nitric acid (HNO3), copper sulphate-16 % sulfuric acid (CuSO4-5H2O-16 % H2SO4) and cooper sulphate-50 % sulfuric acid (CuSO4-5H2O-50 % H2SO4), is studied in an AISI 347 austenitic stainless steel stabilized with 0.61 mass % Nb and hot rolled to a seamless pipe with 273.1 mm in diameter and 18.2 mm in thickness.

Warehousing has undergone a fundamental transformation over the past thirty years. From a time when the fork lift truck was the most intricate piece of warehousing equipment, today's computer hardware and software now allow the construction of completely automated complexes. The technology which makes this state of affairs possible can bring key benefits such as reduced inventory, increased management control, greater accuracy and better labour efficiency, though at the same time costs incurred should be justifiable. This article attempts to give some guidelines for decisions in each of these areas.

The effectiveness of television distortion as a negative reinforcer was analyzed. Contingency arrangements involving television distortion were found to be capable of (a) accelerating the work rate of a naive, mildly retarded subject on a simulated production-line task involving card-sorting, and (b) reducing gross hyperactivity of a mildly retarded subject. An escape-avoidance contingency was arranged for the production-line behavior of the first subject and a punishment contingency for the hyperactive behavior of the second subject. Television distortion appears to be an effective and practical negative reinforcer for use in behavior modification.
