dental organ. They are joined by the dentine; pulp chambers and canals may be linked or separated depending on the developmental stage when the union occurs. This process involves epithelial and mesenchymal germ layers resulting in irregular tooth morphology (1). Moreover‚ the number of teeth in the dental arch is less than normal. A review of the literature reveals great difficulty in correctly differentiating fusion and gemination. For a differential diagnosis between these anomalies‚ the dentist

some of the tests were used only for gram (+) others were even more specific and used only for cocci bacteria .The first procedure have been done was to observe and record the morphology of the unknown sample. However‚ Gram stain should be done to be sure that unknown sample were gram positive and to identify cells morphology. After that biochemical tests were chosen for unknown identification . first of all was done the catalase test to differentiate between the two types of cocci bacteria ( Staphylococcus

In addition‚ this group averaged a 22 percent increase in sperm count compared to the control group. A week after they stopped exercising‚ their sperm count and morphology returned to normal; the motility also returned to previous levels after a month. The Urmia University researchers concluded that moderate exercise is an effective

Revised floral formula‚ inflorescence terms Cypripedium calceolus; a complex orchid flower‚ its diagram and its new floral formula Credit: G. Prenner Research into the structure and development of flowers and inflorescences has revealed that traditional descriptive methods are often inadequate. Scientists at Kew have therefore suggested revisions to floral formula and inflorescence terminology. Aesculus octandra has an indeterminate thyrsoid inflorescence.

embryonic craniofacial morphogenesis and thus contributes to the etiology of many craniofacial abnormalities‚ genetic factors must be definitely considered in the etiology of malocclusion. However environment is also believed to influence dentofacial morphology postnatally‚ especially during facial growth. Environmental influence is also very well a component‚ though a small one. Since monozygotic twins will have identical genetic make-up‚ any difference in the dentofacial pattern will be due to environmental

This experiment was catalyzed by some Polyethylene Terephthalate (PET) bottle problems documented by the company. In order to prevent the loss of a customer‚ our goal is to analyze PET bottles‚ preforms‚ and storage conditions. After heating a bottle and preform to one-hundred and eighty degrees Celsius‚ the bottle shrank and became opaque on the top and bottom of the bottle. The preform became completely opaque and kept its original size and shape. The Differential Scanning Calorimeter (DSC) provided
