Reports on infectious diseases acquired by bacteriological laboratory staff from their work emphasize the risk of contracting tuberculosis by handling tuberculous specimens. Recent advances in the chemotherapy of tuberculosis have greatly increased the amount of bacteriology done in routine hospital laboratories, primary culture and then sensitivity tests being required where previously a direc...

During my stay in Riga (one of the oldest cities in Europe' and capital of a country about the same size as the Republic of Ireland with a population of 2 5 million) I spoke at the Ministry ofHealth and at the First Children's Hospital. I was privileged to have Professor I Lazovskis (Juris's father and professor of internal medicine at the Latvian Medical Academy) as my interpreter. As we sat i...

INTRODUCTION Reconstructing a torn anterior cruciate ligament (ACL) in a knee that has had prior ACL surgery presents challenges, especially if multiple procedures have been done in the past. Revision ACL surgery will continue to become more common as the number of primary ACL reconstruction procedures continues to increase. A common problem faced by the surgeon in the revision setting is an en...

Equine infectious anaemia (EIA) is a disease with an almost worldwide distribution and is of considerable importance to the equine industry, primarily because it is one of only 11 notifiable equine specific diseases listed by the World Organisation For Animal Health (OIE). Equine infectious anaemia is caused by EIAV (equine infectious anaemia virus), a blood-borne retrovirus belonging to the le...

The purpose of optimizing isolator parameters is to have a system that is stiff at low frequency but soft in high frequency. However, in this case a small amount of transmitted force will cause a large displacement in isolator. Exceeding the allowable relative displacement may cause serious damage to the system. Therefore a trade off between the transmitted force, which is indicated by absolute...

washers, fans and other devices may be required. This kind of setup is typically a requisite for the warm air in the summer to create a comfortable environment for the passengers. The last type of ventilation is in the case of an emergency, like the times the train is caught in fire. This kind of situation requires larger amounts of ventilation, which needs to be provided by mechanical means. F...

Over the past few weeks England and Wales have endured the most widespread flooding for more than 50 years. By the end of the first week of November more than 3000 homes had been flooded and transport had been disrupted; in some areas water supplies have been contaminated, and a hospital has been evacuated. Flooding accounts for 40% of all natural disasters worldwide and causes about half of al...

A study was conducted to determine the ability of neural networks to extract high level control information from cylinder pressure data. Various experiments were performed us ing neural networks for pattern recognition on a series of data files consist ing of cylinder pressure versus crank angle. The goal of these experiments was to estimate spark timing based on the cylinder pressure signature...

Purpose The National Cancer Institute reported an increased incidence of kidney cancer over the past 30 years, projecting over 54,000 new cases in 2008 [1]. Surgical intervention is the established method of treatment, with partial nephrectomies preferred when physiologically practical [2, 3]. Along with nephron-sparing approaches, minimally invasive methods have gained ground due to reduced bl...

The aim of the study was to asses the effect of the use of interdental brushes (IDB) in patients as an adjunct to toothbrushing compared. During brushing, optimal cleaning results when the bristles work with their ends manual or electric devices, proving a greater efficiency of the prototypes ( ). “Plaque removal efficacy of power and manual toothbrushes: a comparative. Comparative cleansing ef...
