Agents that give rise to skin color are skin thickness, the skin’s light refraction and absorption properties, vascular status, levels of oxidized and reduced hemoglobin, carotenoid content and, most importantly, the pigment melanin. Melanocytes, cells responsible for pigment formation, are present in the basal layer. Melanocytes are most concentrated in the central part of the face and most sp...

‎Let G=(V(G),E(G)) be a simple connected graph with vertex set V(G) and edge‎ ‎set E(G)‎. ‎The (first) edge-hyper Wiener index of the graph G is defined as‎: ‎$$WW_{e}(G)=sum_{{f,g}subseteq E(G)}(d_{e}(f,g|G)+d_{e}^{2}(f,g|G))=frac{1}{2}sum_{fin E(G)}(d_{e}(f|G)+d^{2}_{e}(f|G)),$$‎ ‎where de(f,g|G) denotes the distance between the edges f=xy and g=uv in E(G) and de(f|G)=∑g€(G)de(f,g|G). ‎In thi...

introduction cement has a wide industrial usage and it is the leading cause of occupational skin diseases among construction workers, which are present as contact urticarial and contact dermatitis. case presentation a 79-year-old water sewage worker man referred to our department with numerous symmetric hyper-keratotic papules with an erythematous base on both hands and feet for about 20 years....

acanthosis nigricans (an), tripe palm (tp) and sign of lesser trelat (lt) are rare dermatoses which are often seen with malignant conditions. acanthosis nigricans occurs both on the skin and mucus membranes as velvety hyper pigmented lesions in the flexors and around the neck, or papillomatous and verrucous lesions on the lips and buccal mucosa. these para neoplastic dermatoses are generally li...

Mantel cell lymphoma is one of the small B-cell non-Hodgkin’s lymphomas and usually involves lymph nodes, bone marrow, spleen, liver, gastrointestinal tract, and Waldeyer’s ring, but rarely skin and orbit. A 53-year-old man presented skin nodules and plaques on the head, trunk, and lower extremities for half a month, and the left periorbital region swelled 4 days ago. Serum calcium and lactate ...

Hypertexture is a powerful and exible procedural modeling tool that is currently limited only by an ine cient rendering mechanism. We analyze the terms of hypertexture functions to obtain an importance measure, capitalize on spatial and image coherence when possible. These enhancements make a guaranteed algorithm for ray-tracing implicit surfaces signi cantly more e cient for rendering hypertex...

Hybrid number system is a generalization of complex, hyperbolic and dual numbers. numbers hybrid polynomials have been the subject much research in recent years. In this paper, hybrinomials related to hyper-Fibonacci hyper-Lucas are defined. Then some algebraic properties newly defined examined such as recurrence relations summation formulas. Also, relation between given. Additionally, by using

this paper provides a review on major ergodic features of semi-independent hyper mv {algebra dynamical systems. theorems are presentedto make contribution to calculate the entropy. particularly, it is proved that thetotal entropy of those semi-independent hyper mv {algebra dynamical systemsthat have a generator can be calculated with respect to their generator ratherthan considering all the par...
