Snap-in compressible biomedical electrode

A replaceable, prefilled electrode enclosed in a plastic seal and suitably adapted for attachment to a reusable, washable cap having snaps thereon is disclosed. The apparatus is particularly adapted for quick positioning of electrodes to obtain an EEG. The individual electrodes are formed of a sponge body which is filled with a conductive electrolyte gel during manufacture. The sponge body is adjacent to a base formed of a conductive plastic material. The base has at its center a male gripper snap. The cap locates the female snap to enable the electrode to be positioned. The electrode can be stored and used quickly by attaching to the female gripper snap. The snap is correctly positioned and located by mounting it in a stretchable cap. The cap is reusable with new electrodes for each use. The electrolyte gel serves as the contact electrode to achieve a good ohmic contact with the scalp

Reducing Stigma toward the Transgender Community: An Evaluation of a Humanizing and Perspective-Taking Intervention

Transgender (TG) individuals are an understudied group at high risk of experiencing discrimination and associated adverse mental health outcomes (IOM, 2011). Although many studies demonstrate that contact reduces negative attitudes toward out-groups, few studies have examined the link between contact and attitudes toward the TG community (Hill & Willoughby, 2005; Walchet al., 2012). This study represents one of the first attempts to understand how to effectively reduce stigma toward the TG community. Results indicate that education alone is not enough to change attitudes; in fact, there is some evidence that associating transgenderism with psychopathology may heighten stigma. Consistent with prior research on stigma towards the mentally ill, the current study suggests that both exposure to intimate media depictions of the “other” (Reinke et al., 2004) and perspective-taking (Mann & Himelein, 2008) could strengthen educational campaigns designed to combat stigma

The factorization of simple knots

For high-dimensional simple knots we give two theorems concerning unique factorization into irreducible knots, and provide examples to show that the hypotheses are necessary in each cas

Ahmed , The Logo of the Elephant Interest Group: Encounters in Marsabit and Notes on His Model and Skeleton

Ahmed , the logo of the Elephant Interest Group, was a male African elephant (Loxodonta africana) that was born about 1919, possibly in the vicinity of Marsabit National Reserve, Kenya, East Africa. The name Ahmed is of Arabic origin (pronounced Ah-med ), and it means praised. At the age of 55 Ahmed was about 3 m (10 ft) tall at the shoulder and weighed approximately 5 metric tons (about 11,000 lbs.). He had huge tusks for his size, measuring about 3 m (10 ft) each and averaging about 70 kg (150 lbs) each. Ahmed\u27s 300 pounds of ivory attracted hunters and, as a result, raised major concern for his safety among scientists and the general public. A total of 5,000 letters and cards was delivered to the East African Wildlife Society and resulted in a Presidential Decree issued by the late President Mzee Jomo Kenyatta to protect Ahmed. In addition, a team of human soldiers was assigned to watch his whereabouts around the clock. On January 17, 1974 Ahmed died, probably of natural causes, and his carcass was found almost two days later near Lake Paradise, in the Reserve. The skin was already in an advanced stage of decomposition. Ahmed was dissected on the spot by a team from the Zimmermann (1973) Limited Taxidermist, headed by Wolfgang Schenk, and the skeleton was transported to Nairobi, the capital, where it was prepared and mounted by J.C. Hillman. A fiberglas replica of the skin was made by Zimmermann\u27s team. The entire operation lasted two years and cost Kenyan Shillings 143,086 (about US $14,500). Both the skeleton and the replica are now on display at the National Museum of Kenya (NMK) in Nairobi. Ahmed is Kenya\u27s most celebrated elephant; he was and still is regarded as a national monument and remains the symbol of conservation. The NMK and the Kenyan Government should be commended for their tremendous efforts in preserving the remains of Ahmed

Electrochemical characterization of a novel salen type modified electrode

The nickel(II) complex with H2saltMe, a N2O2 Schiff base ligand derived from salicylaldehyde, was oxidatively electropolymerized on Pt electrodes in CH3CN/0.1 mol dm-3 tetraethylammonium perchlorate (TEAP) to generate polymer films that exhibit reversible oxidative electrochemical behavior in a wide potential range (0.0-1.3 V), high conductivity, and stability/durability
