OBJECTIVES The laboratory is considered the cornerstone of tuberculosis (TB) control programme. International review of Ghana's programme in the late nineties identified the laboratory services as the weakest component. Sputum smear microscopy (SSM) being the main method of diagnosing pulmonary TB in Ghana, the training objectives were to: (i) strengthen the knowledge and skills of laboratory p...

Mapping extraction is useful in medical image analysis. Similarity coefficient mapping (SCM) replaced signal response to time course in tissue similarity mapping with signal response to TE changes in multiecho T2-star weighted magnetic resonance imaging without contrast agent. Since different tissues are with different sensitivities to reference signals, a new algorithm is proposed by adding a ...

A total of 560 day-old commercial broiler chicks were used in two experiments conducted to investigate the biotin requirement of broilers fed sunflower seed meal (SSM) based diets. Two basal biotin-deficient diets based on dehulled (Experiment 1) and non-dehulled (Experiment 2) SSM were each supplemented with graded levels of biotin so that the rations had 40, 80, 120, 160, 200, 240 and 280 mcg...

This paper presents a new approach to online adaptation of continuous density hidden Markov model (CDHMM) with a small amount of adaptation data based on speaker space model (SSM) evolution. The SSM which characterizes the a priori knowledge of the training speakers is effectively described in terms of the latent variable models such as the factor analysis or probabilistic principal component a...

In this paper, we introduce a proactive mechanism to protect Internet hosts against network based denial of service (DoS) attacks. We give Internet hosts an ability to explicitly control who to communicate with and therefore avoid potential DoS attacks coming from the others over the Internet. Our approach depends on the availability of the Source Specific Multicast (SSM) service in the Interne...

In this paper, we propose a method for applying a probabilistic statistical shape model (SSM) to automatic segmentation. We use a point-represented SSM which is based on correspondence probabilities instead of point-to-point correspondences as commonly used. In order to combine the a priori knowledge of the SSM with the image information during the segmentation, we employ a deformable surface w...

The Conventional Wisdom that there is a Solar Neutrino Problem and that New Physics is required, is examined. The various Solar Evolutionary Models, (or SSM), are described and in particular the four new 1992 papers. While the Evolutionary models are generally robust, there are important assumptions and uncertainties (screening, nuclear reaction rates etc ) which mean that the errors cannot be ...

Molecular self-assembly permits the spontaneous aggregation of a variety of low molecular weight amino acid subunits into highly ordered aggregates. Functionalisation of water soluble poly(allylamine) with acetyl protected dialanine enables the formation of a biopolymer self-supporting material (SSM). The presence of an enzyme cleavable dipeptide linker renders the SSM responsive to disruption ...

the strawberry spider mite (ssm), tetranychus turkestani ugarov & nikolski, is an important pest of greenhouse cucumber in tropical and temperate regions of the world. the use of the host plant resistance is a basic method to reduce pesticide application in greenhouses. in this study, the biological responses of ssm to six greenhouse cucumber cultivars (puia, hedieh, milad ghadim, milad jad...
