Vieira, F.C.B. - - 2009
Nitrogen-fixing crops and N fertilisation increase soil acidification, but few studies have attempted to evaluate the capacity of soil organic matter to alleviate the Al toxicity in acid no-tilled soils. This study was carried out in a 21-year-old experiment aiming to evaluate the effect of crop systems [fallow/maize (Zea mays ...

The aggregate stability of 56 salt-affected soil samples from the North-east Plateau, Thailand, was related to soil properties. The soils were Typic Natraqualfs and a Typic Endoaqualf, which are commonly used for paddy rice cultivation. The soil textures are mostly clays and clay loams with clay contents ranging from 313 ...

Hydraulic conductivity of soil is strongly dependent on soil structure, which can be degraded during wetting and leaching. It was hypothesised that this structural degradation is dependent on initial aggregate size distribution and soil texture. The general aim of this study was to investigate the effects of aggregate sizes and ...

We evaluated spatial heterogeneity for pH and a comprehensive set of nutrient and trace elements in surface (0-0.1m depth) and subsurface (0.3-0.4m depth) soils across 26.6ha of old-growth, lowland, tropical moist forest, established on a highly weathered soil in Panama. Little is known about spatial heterogeneity patterns of soil properties ...

This paper demonstrates the application of near infrared diffuse reflectance spectroscopy (NIR-DRS) measurements as part of digital soil mapping. We also investigate whether calibration functions developed from a spectral library can be used for rapid characterisation of soil properties in the field. Soil samples were collected along 24 toposequences in ...

At the field level the demand for spatial information of soil properties is rapidly increasing owing to its requirements in precision agriculture and soil management. One of the most important properties is the cation exchange capacity (CEC, cmol(+)/kg) because it is an index of the shrink--swell potential and hence is ...

Osteopetrosis (OP) is a rare heterogeneous group of inherited skeletal dysplasias characterised by osteoclast dysfunction, impaired bone resorption and poor bone remodelling. Three groups can be categorised on the basis of clinical findings. These include neurological symptoms, haematological abnormalities and renal tubular acidosis in the first group. Increased bone density, ...

Fewer than 20 patients born with situs inversus and duodenal atresia have been reported in the literature. We present a patient with this condition. A newborn baby presented shortly after birth with persistent bilious vomiting. An abdominal radiograph showed a right-sided stomach bubble and a second bubble on the left--typical ...

Access to care by a dedicated neurosurgical unit is limited in the developing world, and the vast majority of patients who sustain a head injury are managed by general surgeons. Prevention of secondary brain injury is paramount. While the principles of management are relatively straightforward, delivering this care may be ...

Introduction. The aim of this study was to determine the prevalence of tuberculosis (TB) in anal fistulas at a referral hospital in Cape Town, and to document the clinical features and course of patients with tuberculous anal fistulas.
Elhady, H.M. - - 2009
Aim. To compare surgical and chemical sphincterotomy for treatment of chronic anal fissure.

Background. Fibrolamellar carcinoma (FLC) is an uncommon malignant tumour of hepatocyte origin that differs from hepatocellular carcinoma (HCC) in aetiology, demographics, condition of the affected liver, and tumour markers. Controversy exists whether FLC demonstrates a more favourable prognosis than typical HCC. A review of existing literature reveals a dearth of ...

Termination of breastfeeding in the first six months after childbirth is frequently caused by breastfeeding-related diseases and problems of the breast such as pain, milk stasis or mastitis. The aim of this study was to evaluate the relationship between psychological stress and the occurrence of breastfeeding associated disorders. In a ...
McAllister, Helen - - 2009
Whilst breastfeeding is undoubtedly best for both mother and baby, many factors influence a woman's decision about whether to start and when to cease feeding. This study sought to determine which variables, influenced by midwifery practice, may influence the length of breastfeeding. Mothers who had given birth to a live ...
Agrasada, Grace - - 2009
This paper makes use of data collected in a randomised controlled trial that was designed to test the efficacy of postpartum breastfeeding counselling to increase exclusive breastfeeding among term low birth weight infants in Manila during the first six months. Mothers were randomised to a control group or one of ...
