Perhaps you should try some spelling variations:
biometrika » biometrics
biometrie » biometrics, biometry
biometric » biometrics, geometric, biometry
biometrical » biometricsal, geometrical, biometryal, biometrics, bioelectrical
biometricsal » biometricssal, geometricsal, biometrysal, biometrics, biometrial, biometricai

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((biometrika OR (biometrie OR biometric)) OR ((biometrical OR biomedical) OR biometricsal)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((biometrika or (biometrie or biometric)) or ((biometrical OR biomedical) or biometricsal))".
• Adding a wildcard symbol may retrieve word variants: ((biometrika or (biometrie or biometric)) or ((biometrical OR biomedical) or biometricsal))*.
