The aim of this research was to measure the relative efficiency of forest management plans in north of Iran. In order to fulfill the research, data of 12 forest management plans were collected from the financial balance sheets of Shafaroud Forest Company during a ten years period. First of all, basic Data Envelopment Analysis (DEA) models (BCC and CCR) were used to determine the efficiency. The...

Basal cell carcinoma (BCC) is the most frequent malignant skin tumor, which is associated with both genetic factors and environmental influences. The objective of this study was to investigate the risk factors associated with the occurrence of BCC in the inhabitants of the Western Herzegovina area. The study took place during 1997-2003. We examined the risk factors which are presumably associat...

The magneto-optical Kerr effect (MOKE) is a widely employed technique for the characterization of ferromagnetic thin films. However, a quantitative analysis is usually hampered by the lacking knowledge of precise magneto-optical parameters. We report the thickness dependence (0–60 nm) of the linear and quadratic MOKE in epitaxial bcc-Fe(001) samples and extract a complete set of parameters for ...

Several species within the Burkholderia cepacia complex (BCC) have emerged as significant opportunistic pathogens of patients with cystic fibrosis (CF). BCC infection is typically associated with a poor clinical prognosis and decreased survival. These factors, combined with the existence of highly transmissible epidemic strains, have resulted in strict segregation of BCC- and non-BCC-infected p...

Basal cell carcinoma (BCC) is the most common human tumor. Mutations in the hedgehog (HH) receptor Patched (PTCH) are the main cause of BCC. Due to their high and increasing incidence, BCC are becoming all the more important for the health care system. Adequate animal models are required for the improvement of current treatment strategies. A good model should reflect the situation in humans (i....

Basal cell carcinoma (BCC) is the most common non-melanomatous skin cancer, typically arising in sun-exposed areas such as the head and neck. Defective signaling through the Hedgehog (HH) signaling pathway forms the molecular basis for BCC. Surgery remains the mainstay of treatment. Basal cell carcinoma of the genital tract is rare as is metastatic BCC. We report a case of metastatic BCC in a y...

In Bipartite Correlation Clustering (BCC) we are given a complete bipartite graph G with ‘+’ and ‘−’ edges, and we seek a vertex clustering that maximizes the number of agreements: the number of all ‘+’ edges within clusters plus all ‘−’ edges cut across clusters. BCC is known to be NP-hard [5]. We present a novel approximation algorithm for k-BCC, a variant of BCC with an upper bound k on the ...

Basal cell carcinoma (BCC) is the most common cutaneous malignancy. Giant BCCs are quite rare. They can cause extensive local invasion, disfigurement, and metastasis. We present a case of a 58-year-old woman with an unrecognized and inadequately treated ulcerated giant BCC sized 12.5 × 10.0 cm that occurred on her left lower leg without any sign of metastasis. Neglect and inadequate treatment o...
