Cobalt improves nickel hydroxide electrodes for batteries

Positive nickel hydroxide electrodes containing 20 mole percent of cobalt hydroxide are more efficient than when impregnated to the same degree by weight with nickel hydroxide alone. Charge-acceptance and oxygen-evolution tests indicate cobalt electrodes are more efficient than plain positive nickel hydroxide electrodes at all rates of charge

The Confluence of Faraday's and Kirchoff's Laws in Bioelectrochemical Systems

When external measurements are made of electrochemical systems, including bioelectrochemical, there results an interaction. Such measurements cause electrochemical processes to take place that are significant. This work looks into the nature and significance of the interfacial processes on membrane and membrane phenomena. The conclusion reached is that interfacial processes are important and cannot be overlooked

Improvements of Paediatric Triage at the Emergency Department

__Abstract__ The practice of triage, originated from the French word “trier” which means to sort, was conceived around 1792 by Baron Dominique-Jean Larrey, Surgeon in Chief to Napoleon’s Imperial Gard. In these days, triage was used to identify soldiers whose injuries were readily treatable in order to return them to battlefield at the earliest opportunity. In 1846, the British naval surgeon John Wilson was the first who argued that treatment should be given first to patients who need immediate and potentially successful treatment. During World War I, the introduction of new weapons created an unprecedented number of potentially treatable mass casualties. This led to a wide introduction of the term “triage” and to a new definition of its concept, in which triage was not only aimed at sorting treatable patients from untreatable patients, but also took into account the complexity of treatable patients in order to save as much patients as possible. Nowadays, triage aims to prioritise patients according to their medical presentation in situations with modest scarcity of health care resources. This scarcity of resources is not only present at the military battlefield or in case of mass casualties and disasters, but can also occur at the emergency department (ED) or in the hospital settings with limited numbers of beds such as the intensive care unit. Although all these settings have distinguishing features, each requires the presence of a trained health care worker (“triage nurse”) to assess the patient’s medical needs, and an established system or plan to determine patient’s priority

Sinter of uniform, predictable, blemish-free nickel plaque for large aerospace nickel cadmium cells

A series of nickel slurry compositions were tested. Important slurry parameters were found to be the nature of the binder, a pore former and the method of mixing. A slow roll mixing which is non-turbulent successfully eliminated entrapped air so that bubbles and pockets were avoided in the sinter. A slurry applicator was developed which enabled an equal quantity of slurry to be applied to both sides of the grid. Sintering in a furnace having a graded atmosphere characteristic, ranging from oxidizing to strongly reducing, improved adhesion of porous sinter to grid and resulted in a uniform welding of nickel particles to each other throughout the plaque. Sintering was carried out in a horizontal furnace having three heating zones and 16 heating control circuits. Tests used for plaque evaluation include (1) appearance, (2) grid location and adhesion, (3) mechanical strength, (4) thickness, (5) weight per unit area, (6) void volume per unit area, (7) surface area and (8) electrical resistance. Plaque material was impregnated using Heliotek proprietary processes and 100 AH cells were fabricated

Interest in bariatric surgery among obese patients with obstructive sleep apnea

BACKGROUND: Standard obstructive sleep apnea (OSA) therapies are poorly tolerated. Bariatric surgery is a potential alternative but the level of interest in this intervention among OSA patients is unknown. OBJECTIVES: Determine the proportion of OSA patients who would be interested in bariatric surgery. SETTING: Sleep clinics, United States. METHODS: Consecutive adult patients with untreated severe OSA and a body mass index of 35-45 kg/m2 were approached. Patients at low perioperative risk and no urgent indication for OSA treatment were invited to a separate informational visit about bariatric surgery as primary treatment for OSA. RESULTS: Of 767 eligible patients, 230 (30.0%) were not at low perioperative risk, 49 (6.4%) had drowsy driving, and 16 (2.1%) had no insurance coverage for bariatric surgery. Of the remaining 482 patients, over one third (35.5%) were interested in bariatric surgery. Surgical interest was 47.2% in women versus 27.6% in men (
