Microbiological studies were carried out in a small poultry farm in a Community in South West Nigeria following a report of acute diarrhea in 6-week old broilers, catarrh and cough in the poultry attendants. Nasal swabs were collected from 25 symptomatic and 5 asymptomatic attendants. Swabs were collected from the cloacae of 100 birds with diarrhea. Twenty-five (100%) symptomatic attendants car...

Many burrowing petrels are able to return to their nests in complete darkness. The well-developed anatomy of their olfactory system and the attraction that food-related odour cues have for some petrel species suggest that olfaction may be used to recognize the burrow. In contrast, surface-nesting petrels may rely on visual cues to recognise their nest. We performed experiments on nine species o...

Face detection is a key problem in building automated systems that perform face recognition. A very attractive approach for face detection is based on multiresolution images (also known as mosaic images). Motivated by the simplicity of this approach, a rule-based face detection algorithm in frontal views is developed that extends the work of G. Yang and T.S. Huang. The proposed algorithm has be...

W. McC., age 17 years. This patient attended E.N.T. Extern and was admitted to the Royal Victoria Hospital on the 16th September, 1949. He complained of nasal obstruction for one year which was noticed first on the right side and later on the left. Four months before admission he had a severe epistaxis, during which he lost a considerable amount of blood. He was treated six months previously fo...

A human face provides a variety of di erent communicative functions. In this paper, we present approaches for real-time face/facial feature tracking and their applications. First, we present techniques of tracking human faces. It is revealed that human skincolor can be used as a major feature for tracking human faces. An adaptive stochastic model has been developed to characterize the skin-colo...

Supernumerary nostril is a very rare congenital anomaly. It can be unilateral or bilateral, and it sometimes occurs in the presence of other congenital deformities. Behind the external opening of a supernumerary nostril is a small accessory nasal cavity, which may or may not communicate with the normal nasal cavity on the same side. We describe a new case in which the supernumerary nostril with...

Sleep apnea is a syndrome that is characterized by sudden breathing halts while sleeping. One of the common treatments involves wearing a mask that delivers continuous air flow into the nostrils so as to maintain a steady air pressure. These masks are designed for an average facial model and are often difficult to adjust due to poor fit to the actual patient. The incompatibility is characterize...

In this paper we present a non-intrusive model-based gaze tracking system. The system estimates the 3-D pose of a user’s head by tracking as few as six facial feature points. The system locates a human face using a statistical color model without any mark on the face and then finds and tracks the facial features, such as eyes, nostrils and lip corners. A full perspective model is employed to ma...

On Thursday, 16 June, 2011 a two months old male Kano brown goat was presented to the Niger State Veterinary Hospital, Bosso-Minna with multiple facial abnormalities. History revealed that the flock did not have antecedents of malformations or apparent reasons that induced the abnormalities. Phenotypical examination revealed that the goat could have been under the influence of some teratogen or...

We have measured upper airways resistance from the trachea and from the pharynx to the atmosphere, EMG of genioglossus muscle, and the sound of snoring, in anaesthetized greyhounds breathing spontaneously through the upper airways. Using extra-corporeally produced continuous flow we determined flow/pressure curves for the upper airways in an expiratory direction and analysed them in terms of re...
