INTRODUCTION AND OBJECTIVES Coal exploitation technology could have affected the deformation of ground under a housing estate in the Upper Silesia agglomeration. The 10-storey apartment building began to deviate from the vertical. These factors affected the housing conditions of inhabitants in the block of flats. From 1991-2001, coal-mine surveyors monitored the vertical deviation. The inhabita...

OBJECTIVE To compare two methods of developing short forms of the Malaysian Oral Health Impact Profile (OHIP-M) measure. METHOD Cross sectional data obtained using the long form of the OHIP-M was used to produce two types of OHIP-M short forms, derived using two different methods; namely regression and item frequency methods. The short version derived using a regression method is known as Reg...

We review the application of the time-dependent close-coupling method to calculate energy and angle differential cross sections for the electron-impact ionization of atoms and molecules. PACS Numbers: 34.80.Dp, 34.80.Gs.

Health impact assessment (HIA) is an approach that has experienced increased activity and wide support within England. This is reflected in the large number of HIAs being undertaken at local and regional levels, by the advocacy of HIA in many national policy documents, and by the setting up of specialized HIA posts and centres. To continue this level of support, and to justify any increase, the...

This study examined a wide range of variables relating to the practice patterns of 692 Ontario chiropractors (approximately 30% of all registrants in the province) who subscribed to the Ontario Chiropractic Association's Patient Management Program. It analyzed the 2000-2001 data of these chiropractors and provided important information on such factors as practitioner and patient demographics, p...

Guards on machine tools are meant to protect persons from injuries caused by parts ejected with high kinetic energy from the machine's working zone. With respect to stationary grinding machines, Standard No. EN 13218:2002, therefore, specifies minimum wall thicknesses for guards. These values are mainly based on estimations and experience instead of systematic experimental investigations. This ...

Measuring the impact of drug resistance is an important step in understanding the scope of the problem and formulating policies to limit the emergence and spread of resistant organisms. Studies have focused on measuring the increased costs, morbidity, and mortality in patients with infections due to resistant versus susceptible organisms. These have generally found that resistance worsens outco...

Biological materials immersed in vegetable and mineral oil, such as rattan armor and wooden sleepers, have been extensively used since ancient times because of their excellent mechanical properties. This study quantitatively investigated the viscoelasticity and tribological performance of lignum vitae immersed in poly-alpha-olefin (PAO) and tung oils (Aleuritesfordii Hemsl.) to reveal the mecha...

It is almost impossible to imagine veterinary medicine today without the use of antimicrobials. Shortly after their discovery, antimicrobials found their way into the veterinary world. They have brought many benefits for the health and welfare of both animals and people, such as the lessening of pain and suffering, reduction in shedding of (zoonotic) bacteria and the containment of potentially ...
