AIMS To prospectively compare the efficacy and safety of pressure topical anaesthesia in punctal occlusion by using cautery in the treatment of dry eye syndrome (DES) with that of conventional treatment by using needle injection of anaesthetic agents. METHODS In a randomised controlled trial, 18 consecutive adult patients with DES requiring punctal occlusion were recruited over a 10 month per...

The number of injector holes and the fuel-injection pressure in an internal combustion engine can affect performance exhaust emissions. Conversion a port-injection gasoline to HCNG direct-injection improves In addition, increasing injection helps increase performance. this study, AVL Fire software was used perform simulation by certain adjustments. applied mods 15, 20, 25 bars, numbers were 3 6...

Motor Diesel dipengaruhi oleh beberapa aspek operasional. Diantaranya: waktu pengi­njeksian bahan bakar (timing injection), tekanan (fuel pressure), dan udara yang masuk (boost pressure). Modifikasi akan dilakukan untuk mengubah parameter menggunakan piggyback. Terdapat tiga hal diteliti, yaitu mengamati perubahan pada daya torsi jika fuel pressure, injection timing, turbo. Pengujian meng­gunak...

introduction: epinephrine-containing lidocaine is the most used anestheic drug in dentistry. the aim of this study was to investigate the hemodynamic changes following local infiltration of 2%lidocaine with 1:80,000 epinephrine in subjects undergoing orthognatic surgery under general anesthesia. methods: twenty five patients without any systemic disease participated. after general anesthesia, t...

Fluid injection has been applied in many fields, such as hazardous waste deep well injection, forced circulation in geothermal fields, hydraulic fracturing, and CO2 geological storage. However, current research mainly focuses on geological data statistics and the dominating effects of pore pressure. There are only a few laboratory-conditioned studies on the role of drilling boreholes and the ef...

Dimethyl Ether (DME) has been attracting attention as an alternative fuel for diesel engines because it can be produced from various feed stocks and does not create smoke. On the other hand, a DME truck require a large volume fuel tank in order to obtain the running distance equivalent to diesel trucks due to the lower energy content per unit volume of DME, and un-burned gas and fuel consumptio...

the analytical theory of one dimensional, dispersion free miscible displacement of oil by injection gas with nc component has shown that: the mmp is the lowest pressure at which any one of the initial oil, injection gas or crossover key tie lines becomes critical, which means that its length approaches to zero. in this paper, we propose a method for a solving multi component system based on ana...

Various types of high-pressure equipment, including airless paint sprayers, hydraulic apparatus and grease guns, are used in industry, in farming and in the home. Injection injuries from this equipment usually involve the hand and may initially appear benign. However, these injuries must be treated quickly and aggressively to prevent significant long-term disability.

Despite their appearance for over 20 years, high-pressure injection injuries to the hand are often grossly undertreated or mistreated, resulting in usually avoidable permanent impairment--often with amputation. Primary care physicians, and especially emergency room physicians, must be aware of the serious nature of this usually innocuous-appearing injury and immediately refer such patients for ...

INTRODUCTION A previously healthy 65-year-old male presented to the emergency department complaining of a burn to his right forearm. Just prior to arrival the patient was working at a tool and die company casting products with molten aluminum where he inadvertently caused his injury. Physical examination revealed a burn to the right forearm of varying degrees of severity. A non-painful charred ...
