    This paper presents the Sokoto Coventry Fingerprint Dataset (SOCOFing), a biometric fingerprint database designed for academic research purposes. SOCOFing is made up of 6,000 fingerprint images from 600 African subjects. SOCOFing contains unique attributes such as labels for gender, hand and finger name as well as synthetically altered versions with three different levels of alteration for obliteration, central rotation, and z-cut. The dataset is freely available for noncommercial research purposes at: https://www.kaggle.com/ruizgara/socofin

    IMSP Institutul Oncologic, Al XI-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” din Republica Moldova și cea de-a XXXIII-a Reuniune a Chirurgilor din Moldova „Iacomi-Răzeșu” 27-30 septembrie 2011Articolul prezintă rezultatele utilizării unei metode de plastie a defectelor totale ale aripei nazale la 12 pacienți pe parcursul anilor 2009 – 2011. În studiu au fost incluşi 12 pacienți cu afectarea tumorală totală a aripei nazale, limitată doar la acestă subunitate a feței. Toți pacienții incluşi în studiu sînt bărbați şi în toate cazurile tumoarea afecta aripa nazală pe toată grosimea acesteia. Structura morfologică a tumorii: 8 cazuri (66,7%) – carcinom bazocelular, 3 cazuri (25,0%) – cancer pavimentos cheratinizat, un caz (8,3%) – tumoare malignă din anexele pielii. Tratamentul chirurgical a constat din electroexcizia tumorii în limitele securității oncologice. Plastia defectului s-a efectuat în aceiaşi etapă, după medota propusă de noi: defectul pielii şi mucoasei vestibulului nazal a fost închis utilizînd o grefă cutanată liberă, fixată la marginile interne ale defectului cu fire separate de catgut. Reconstrucția conturului extern al nasului s-a efectuat cu un lambou cutano-adipos nazo-labial, cu baza dispusă inferior (8 cazuri) sau superior (4 cazuri). Intervenția se finisa cu tamponarea cavității nazale operate, pentru a asigura aderarea strînsă a grefei cutanate la lamboul prelevat, demeşarea s-a efectuat la ziua a 5-6 postoperator. Plăgile donatoare au fost suturate primar. În toate cazurile noi am obținut o vindecare per primam de 100% atît a grefei cutanate, cît şi a lamboului nazo-labial, fără morbiditate în plăgile donatoare, cu un rezultat estetic şi funcțional bun în toate cazurile. Metoda de plastie propusă de noi permite vindecarea rapidă a plăgii postoperatorii şi reconstrucția nu numai a țesuturilor cutanate ale aripei nazale, ci şi a porțiunii nazale vestibulare cuteneo-mucoase.The article presents the results of using an original combined method of plasty of total defects of ala nasalis in 12 patients during the years 2009 to 2011.The study included 12 patients with complete tumor infiltration of ala nasalis, limited only to this functional - aesthetics subunit of the face . All patients in the study are men and in all cases the tumor affected the entire thickness of ala nasalis. Morphological structure of the tumor: eight cases (66.7%) - basal cell carcinoma, 3 cases (25.0%) – squamous cell carcinoma, one case (8.3%) - malignant tumor of skin annexes.Surgical treatment consisted of tumor excision within security margins. Defect plasty was performed on the same stage, using our method - the nasal vestibule skin and mucosal defect was closed using a free skin graft, taken from the inner part of the arm and fixed to the internal edges of the defect with separate catgut sutures. Reconstruction of the external contour of the nose was performed with a nasolabial cutaneoadipous flap, inferior (8 cases) or superior (four cases) based. The intervention finished with nasal packing to ensure tight adherence of the skin graft to the flap, removal was performed on postoperative day 5-6. Donor areas were closed by primary suture.In all cases we obtained a 100% healing of both the first skin graft, and the nasolabial flap with no morbidity in donor areas, with a good aesthetic and functional results in all cases.The proposed new method of closure allows rapid postoperative wound healing and tissue reconstruction not only of the skin of ala nasalis, but also of the vestibular cuteneo-mucous part
