Morphological characteristics of head hairs and hairs from other parts of the body in the population of Asia

The paper describes specific morphological features of hairs from the head, beard, chest, axilla, pubis of the native population of Syria, India, Lebanon, Jordan, Yemen, Nepal, Palestine, Bahrain, Iraq and some residents of the Eastern Europe (Russians, Belorussians, Ukrainians). The hairs were studied macroscopically and microscopically (light microscopy). Digital data on hair thickness and number of lines of cuticula pattern were analysed using methods of variance statistics. Original information on some macro- and microscopic characteristics of hair has been obtained for citizens of the above countries.     

Study of microinjuries to hair cuticle of human head by scanning electron microscopy

The author presents the data on microclues in the free edges of hair cuticles of human head: microinjuries, microdefects (cracks, breaks, clefts, large and small waves) in representatives of Asia, Africa, Latin America, and Eastern Europe. The studies were carried out by scanning electron microscopy. Microinjuries of cuticle cells forming during hair combing by different types of combs and as a result of "permanent" curling are described. Scanning electron microscopy at the optimal magnification of x 3000 is a highly informative method for investigating microinjuries to the hair cuticle as additional signs in expert evaluation of the hair.     

Structure of hair on the head and other parts fo body in Latin Americans

The structure of hairs from the head, chest, armpits, and pubis of residents of Latin America (Bolivia, Salvador, Panama, Ecuador, Chile, Nicaragua, Venezuela, Peru, Brasil, and Mexico) has been studied. New data on macro- and microscopic characteristics of hairs of the population of the above countries were obtained (color, shape, length, thickness of hair; number of cuticle lines; characteristics of hair layers, shapes of transverse sections, etc.).     

The characteristics of the macro- and trace element composition of the hair in the peoples of Asia, Africa and Latin America

Macro- and trace element composition of hairs on the head, chest, in the armpits, and on the pubis in the population of Asia, Africa, and Latin America adapted and not to the climate, geographic and ecological conditions of the Russian Federation (Moscow) is studied by spectrography (DPS-13 spectrograph). Element composition of residents of 16 countries is analyzed by variation statistics methods using PC: Lebanon, Syria, Yemen, Bahrain, India, Sierra Leone, C?te d'Ivoire, Rwanda, Kenya, Sudan, Mexico, Ecuador, Bolivia, Brasilia, Columbia, and Chile. Hairs from residents of East Europe (Russians, Byelorussians, Ukrainians) living in Moscow for 6-8 years (adapted) were the reference for comparison. A total of 371 specimens of hairs were examined. Hairs from adapted and not adapted residents of the above-listed countries and continents differ significantly from each other and from the hairs of Russians, Byelorussians, and Ukrainians living in Moscow.     

Morphology of hairs on the head and other parts of the body in the residents of Africa

The morphology of hairs from the head, beard, chest, armpits, and pubis was studied in indigenous population of Sudan, Sierra-Leone, Cote d'Ivoir, Ruanda, Nigeria, Gambia, Kenya, Uganda, Burundi, Zaire, Southern African Republic, Angola, Benin, and Guinea Bissau. A total of 327 hair specimens were examined. A number of new parameters of hairs were determined: thickness, number of cuticle pattern lines per mm, optic edge pattern, cuticle patterns, methods for detecting the cortical and medullar layers, width of hair layers and their transverse sections. The resultant morphological signs are new specific signs for African residents (Negroid) which can be used in forensic medical studies for identifying the race appurtenance of hairs.     

Study of transverse sections and pigment granules of the hair of persons of various nationalities

Data on the form of transversal sections and pattern of pigmental granulations of hair obtained from the inhabitants of some countries of Asia, Africa and Latin America are presented. These hair characteristics were compared to those of hair obtained from the USSR citizens (Russian, Buelorussian, Ukrainian, Georgian, Azerbaijanian people). Possibility of race identification of hair using set of morphological characteristics is stressed.     

What is performance measurement for? Multiple uses of performance information within organizations

Recent research in performance measurement has focused on the tension between two uses of performance information: ‘passive’, to ensure compliance, and ‘purposeful’, to improve services. This article presents an in-depth study of two public sector organizations in England and shows that the main tension may actually lie between a combined purposeful and passive use, and an exclusively passive one. This tension was most pronounced between organizational levels, where a combined use was dominant among senior managers, and an exclusively passive one was prevalent among middle managers and frontline staff. This split was not intentional—instead, it reflected how people interpreted the role of performance measurement, suggesting that simply promoting greater use of information may not be sufficient for linking measurement with service improvement. This study extends the theoretical understanding of the dynamics of performance information use in organizations and generates implications for using performance measurement to improve service delivery.     

Study of cuticle patterns of head hairs by scanning electron microscopy

Cuticle patterns of 5 subjects living in different countries have been studied under a scanning electron microscope. Hair cuticle pattern in different individuals can be complex, simple, or mixed type. The most incident is the complex type of hair cuticle pattern (75-80%), while the simple type is much more rare (15-20%) and the mixed type still more rare (2-5%). Variation statistical analysis helped differentiate hairs from aborigines of some countries of Asia, Africa, Latin America, and East Europe by the number of cuticle pattern lines. High efficiency of scanning electron microscopy in studies of hair cuticle patterns is shown.     

Content of macro- and trace elements in human body and environmental factors

Evaluations of the mean normal, increased, or decreased concentrations of macro- and trace elements in human body and biological media (e.g. hairs) are discussed. It is proposed that the element composition in an individual (mean normal, increased, or decreased) be evaluated by comparison with the mean level for the region, which depends on the biological, geological, and chemical (soil, water, etc.), ecological, climatic, and geographical factors. The efficiency of such an approach is demonstrated by forensic medical and clinical physiological findings.
