Fusion welding and non-fusion welding Fusion welding is defined as a welding process of using heat by melting the base of metals in order to joint similar types of metals together. Filler is used in this welding process to provide bulk and strength to the welded joint [1]. Whereas non-fusion welding which is known also as solid state welding is a welding process where a particular amount of heat is applied to the joining metals which essentially below the melting point of the base metals that being

ARTIFICIAL VISION ABSTRACT: Blindness‚ the most severe form of visual impairment‚ deprives people the ability to move about unaided. It is the most feared ailment in the present world. The leading causes of chronic blindness include cataract‚ glaucoma‚ age-related macular degeneration‚ corneal opacities‚ diabetic retinopathy‚ trachoma‚ and eye conditions in children (e.g. caused by vitamin A deficiency). Artificial vision has been a challenging task for the opto bionics. But now‚ a limited form

Tungsten trioxide (W ) is a transparent film but on electrochemical reduction‚ W give the electrochromic effect (blue coloration to the film). Although‚ there is still controversy about the detailed coloration mechanism‚ it is generally accepted that

The purpose of this paper is to briefly explain and analyze the characteristics involved during the treatments of Electroconvulsive Therapy (ECT)‚ including a brief history of ECT‚ the indications for using ECT‚ the process during the procedure‚ and a brief personal analysis and discussion about the treatment‚ and a synopsis of the article “I Feel Good‚ I Feel Alive”. In the early 1900’s‚ treatment for noetic illness was constrained with psychotherapy or inpatient confinement being the

processor transmits the digitally-coded sound through the coil on the outside of your head to the implant. In which the implant then converts the digitally-coded sound into electrical impulses and sends them along the electrode array placed in the cochlea. Lastly the implant’s electrodes stimulate the cochlea’s hearing nerve‚ which the4n sends the impulses to the brain where they are interpreted as sound. Opposed to the hearing aid the cochlear provides a better hearing quality and a previous study

and 100 times (10 times 10) more alkaline than pH 8. Primary pH standard values are determined using a concentration cell with transference. This measures the potential difference between a hydrogen electrode and a standard electrode. Measurement of pH for solutions can be done with a glass electrode and a pH

Design of Steel Structures Prof. S.R.Satish Kumar and Prof. A.R.Santha Kumar 3.3 Welding and welded connections Welding is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. It is distinguished from other forms of mechanical connections‚ such as riveting or bolting‚ which are formed by friction or mechanical interlocking. It is one of the oldest and reliable methods of joining. Welding offers many advantages over

ammonia‚ and hydrogen. The chemicals were all sealed inside a sterile array of glass flasks and flasks connected in a loop‚ with one flask half-full of liquid water and another flask containing a pair of electrodes. The liquid water was heated to induce evaporation‚ sparks were fired between the electrodes to simulate lightning through the atmosphere and water vapor‚ and then the atmosphere was cooled again so that the water could condense and trickle back into the first flask in a continuous cycle.

costs of drug treatment are about 1‚000 to 6‚000 dollars per patient per year1. Subthalamic deep brain stimulation (STN DBS) is a now commonly used method in which two electrodes are implanted in a patient’s subthalamic nuclei to decrease the motor symptoms and instabilities of the medication in PD. Usually there are two electrodes implanted‚ one in each hemisphere‚ even though PD occurs asymmetrically. That would make it logical to think that a unilateral implantation could be successful as well2
