This paper describes fundamental experiments of a new biomass ironmaking that employs low-grade iron ore and woody biomass for promoting the direct reduction, FeO + C ) Fe + CO, in which dehydrated, porous limonite iron ore was filled with carbon deposited from the biomass tar, biotar. In our experiments, three types of iron ores containing differe

Introduction: Asymmetric breast tissue is a relatively common mammographic finding and is usually benign. It might be due to a normal variation, postoperative changes or hormone replacement therapy. However, an asymmetric area may indicate a developing mass or an underlying cancer. Method: We collected random cases of asymmetric breast densities on

We describe simple implementations of homotopy (also called continuation) algorithm for determining the proper resistor to dissipate energy at a specified rate of an electric circuit. Homotopy algorithm can be considered as a developing of the classical methods in numerical computing such as Newton- Raphson and fixed point methods. In homoptopy met

Introduction: Interpretation of mammogram is a challenging task and the performance level of readers is known to vary widely between general radiologist and breast imaging experts. R2-CAD is a software-based system to identify regions of the mammogram with suspicious features and to draw the reader’s attention to these areas and decide whether th

Cervical vertebral osteomyelitis is rare. While an early and correct diagnosis is critical to prevent catastrophic neurological injury, the diagnosis of cervical vertebral osteomyelitis is often difficult because of its rarity and variable symptoms. We present a case of C1 and C2 vertebrae osteomyelitis with a misleading presentation and its fatal

Dysphagia of vascular origin is termed dysphagia lusoria and it is relatively uncommon. Amongst the vascular causes, aberrant right subclavian artery is the most common. This case illustrates the usefulness of imaging in the investigation of dysphagic patient for an accurate diagnosis and appropriate management of the condition.Introduction Dysphag

The current Internet architecture with its best effort service model is inadequate for real time applications that need certain Quality of Service (QoS) assurances. Several QoS models are proposed, however, these models were proposed for static environment. The main aim of this paper is to propose a set of protocols that enable the support of seaml

Hypertension and obesity are established and independent risk factors for cardiovascular diseases. There are important inter-relationships between these two factors that may explain the aetiology of cardiovascular diseases. To determine the prevalence of hypertension and obesity in a rural community setting in Malaysia, and to identify their associ

The main challenges for biodiesel production are the cost of raw material (fats and oils) and the cost of processing. In this study free fatty acid (FFAs) of sludge palm oil has been converted to fatty acid methyl ester via acid-catalyzed reaction using ultrasonic energy. Batch esterification process of SPO was carried out to study the influence of

Aborigines have been living off the forests for ages. They must have also experienced sicknesses. The resources they have are just the forest. • The forests must also be the resources of ‘medicines’ – primarily plants. Even though the effectiveness is limited, may be due to administration rather than plants efficacy, their practices have be
