87 86 Ž In this study, variations in MgrCa, SrrCa and Srr Sr ratios in a Holocene Belgian speleothem cave secondary . carbonate deposit are interpreted in terms of changes in water residence time and changes in weathering processes, possibly Ž . induced by changes in West European climate. A stalagmite from the Pere Noel cave Belgium was dated with the TIMS ` ̈ UrTh method and was deposited bet...

The object of tissue analysis is to secure an accurate representation of the condition of the tissue in its normal state. This can be accomplished only by first maintaining conditions which prevent further changes during the final preparation of the tissue. In the procedures now in general use the tissue is rapidly frozen in liquid air (1) or a CO2 snow-ethyl chloride mixture. It is then either...

In many places in the world, soil information is difficult to obtain and can be non-existent. When no detailed map or soil observation is available in a region of interest, we have to extrapolate from other parts of the world. This chapter will discuss the Homosoil method, which assumes homology of soil-forming factors between a reference area and the region of interest. This includes: climate,...

Intramuscular injections (IM) are a common yet complex technique used to deliver medication deep into the large muscles of the body. More than 12 billion IM injections are administered annually throughout the world. However, it is not a benign procedure, and unsafe injection practices are estimated to have significant impacts on patient morbidity and mortality and result in millions of dollars ...

CASE REPORT A 19-year-old man presented to our outpatient clinic with a perineal mass and discomfort. Examination showed an empty and poorly developed left hemiscrotum. The contralateral testis was in its normal location in the right hemiscrotum (Figure 1). An oval-shaped soft mass was detected in the perineum measuring 4 × 5 × 6 cm. A clinical diagnosis of perineal ectopic testis was made. We ...

BACKGROUND/AIMS Many patients undergoing a flexible bronchoscopy (FB) experience anxiety and discomfort during the procedure. We assessed whether an additional patient visit after a FB would improve patient satisfaction. METHODS The study patients were randomly assigned to a control and post-visit groups. The physicians who were scheduled to perform the FB visited the study patients. The cont...

Loudness discomfort levels (LDLs) were measured in dB HL and SPL at discrete frequencies between 500 to 4000 Hz on 31 hearing-impaired ears using TDH-50P and ER-3A earphones. The results revealed no significant differences in the measured sound pressure level (SPL) between the two earphones at all test frequencies. However, with dB HL measurements, statistically significant differences were rev...

This paper aims to investigate the effect of acceleration on the discomfort of standing passengers. The acceleration levels from different public rail transport lines such as the mass rapid transits (MRTs) and light rail transits (LRTs) of Singapore, as well as the associated qualitative data indicating the discomfort of standing passengers are collected and analyzed. Based on a logistic regres...

Teachers' attitudes towards sexuality education are among the important predictors of their willingness to teach sexuality education programmes in schools. While there is a plethora of studies on teachers' attitudes towards sexuality in developed countries, there is a paucity of such studies in sub-Saharan Africa in general and Tanzania in particular.  This study examined teachers' attitudes to...

The perceptions and experiences among general practitioners (GPs) and nurses in identifying female patients experiencing domestic violence and referring patients to specialist agencies need to be clarified. Eleven GPs and six nurses participating in a multidisciplinary domestic violence training and support programme in east London and Bristol were interviewed. All participants recognised that ...
