and Vagners (1971, 1972) expressed this phenomenon elegantly by introducing the concept of "terminal mode" for the optimum grain size to which a mineral can be reduced, given the force and energy typically available in the glacial environment. Thus, hard, uncleaved or poorly cleaved minerals such as quartz, fcldspar, garnet, pyrite and magnetite dominate either the medium or the fine sand fract...

Primary malignant melanoma of the oesophagus is an exceedingly rare oesophageal neoplasm. It accounts for less than 0.1% of all primary oesophageal tumours. Less than 262 cases have been documented till today. Surgical resection with re-establishment of gastrointestinal continuity is the treatment of choice. However, haematogenic and lymphogenic metastases are common and despite advances in sur...

Today oncologic diseases show an increase in their incidence and prevalence [1]. Adverse effects or complications of the treatments channeled into cure or improvement of people who suffered from these diseases, may be very serious with deterioration in the quality of life of these people.

Personal information is an important precursor for the trust formation process in virtual project teams. However, till today it has remained unclear what specific personal information most trustors prefer. Insight in their preferences as well as in their foundation could support the development of templates that provide communication support to virtual teams. In this paper, we describe and empi...

Introduction No other European gull has shown such a dramatic and rapid change of distribution in the last decades as the Mediterranean Gull Larus melanocephalus.

Zoon's balanitis is an asymptomatic lesion that requires histopathological examination of involved tissue for confirmation of diagnosis. Till today, circumcision is considered as the treatment of choice as topical medical therapy is insufficient to cure the disease and also there was a risk of recurrence after discontinuation of therapy. Herein, we have treated the Zoon's balanitis with 0.1% to...

CAPTCHAs is Turing test are used to distinguish whether a user is a human or a computer. Till today huge number of CAPTCHA schema have been suggest or put forth and applied on miscellaneous websites to secure online services (SOS) from automated decaptcha programs. So development of a good CAPTCHA scheme that is both secure by automated recognition and human usable is an important research prob...
