The objective of this study was to ascertain whether maternal additive genetic variance exists for within-litter variation in birth weight and for change in within-litter variation in piglet weight during suckling. A further objective was to estimate maternal genetic correlations of these two traits with mortality, birth weight, growth, and number of piglets born alive. Data were obtained from ...

Aqueous extract of leaves of M. oleifera was investigated and rationalised for its wound healing activity. The aqueous extract was studied at dose level of 300 mg/kg body weight using resutured incision; excision and dead space wound models in rats. Significant increase in wound closure rate, skin-breaking strength, granuloma breaking strength, hydroxyproline content, granuloma dry weight and d...

BACKGROUND Neurally adjusted ventilatory assist (NAVA) is a pneumatically-independent mode of mechanical ventilation controlled by diaphragm electrical activity (EAdi), and has not yet been implemented in very small species. OBJECTIVES The aims of the study were to evaluate the feasibility of applying NAVA in very small species and to compare this to pressure support ventilation (PSV) in term...

This study conducted to investigate the effects of Potassium Dichromate (K2Cr2O7) and Turmeric Oil (TO) on reproductive efficiency of adult male rats. Twenty four male rats aged 100 days divided randomly into 4 groups. G1 received 1 ml of dimethyle sulfoxide (DMSO) 5% orally as control, G2 received K2Cr2O7 (24 mg/kg orally), G3 received TO dissolve in DMSO 5% (8.5 mg/kg orally) and G4 received ...

BACKGROUND Pulmonary function is impaired during pneumoperitoneum mainly as a result of atelectasis formation. We studied the effects of 10 cm H2O of positive end-expiratory pressure (PEEP) and PEEP followed by a recruitment maneuver (PEEP+RM) on end-expiratory lung volume (EELV), oxygenation and respiratory mechanics in patients undergoing laparoscopic surgery. METHODS Sixty consecutive adul...

A recent survey (Williams, 1995) indicated that over 1.7 million tons of liquid feed were manufactured in the 1994-95 production year. An estimated 45% (708,000 tons) of this liquid feed was used in feedlot diets and 55% (960,000 tons) was specified as non-feedlot and presumably most of this was fed to cattle on forage based diets. Past estimates of liquid feed tonnage indicate it has grown an ...

Diagnostic feature extraction with consideration of interactions between variables is very important, but has been neglected in most diagnostic research. In this paper, a new feature extraction methodology is developed to consider variable interactions by using a fractional factorial design of experiments (DOE). In this methodology, features are extracted by using principal component analysis (...

In this paper, a robust neural network control scheme is proposed for robot tracking tasks. The neural network is trained on-line and the weight tuning algorithm has a small dead zone to overcome bounded disturbances. Under this proposed control scheme, it is shown that tracking error bound is completely determined by neural network approximation error bound, disturbance bound, as well as a con...

There are few available recorded observations in this country on the relationship of the body-weight and the weights of organs. While undertaking this study it was observed that it was likely, in fact, inevitable, to include bodies deposited in the mortuary for varying periods. The possibility of some variation in the weight of a dead body occurring as the result of cold storage by itself was w...
