It has been demonstrated that cross sections of bundles of hair can be effectively studied using image analysis. These studies can help to elucidate morphological differences of hair from one region of the body to another. The purpose of the present investigation was to use image analysis to determine whether morphological differences could be demonstrated between male and female human Caucasian terminal scalp hair.Hair samples were taken from the back of the head from 18 caucasoid males and 13 caucasoid females (Figs. 1-2). Bundles of 50 hairs were processed for cross-sectional examination and then analyzed using Prism Image Analysis software on a Macintosh llci computer. Twenty morphological parameters of size and shape were evaluated for each hair cross-section. The size parameters evaluated were area, convex area, perimeter, convex perimeter, length, breadth, fiber length, width, equivalent diameter, and inscribed radius. The shape parameters considered were formfactor, roundness, convexity, solidity, compactness, aspect ratio, elongation, curl, and fractal dimension.

The effect of fractal dimension (Df) on the determination of representative elementary volume (REV) was investigated through numerical experimentations, in which a new method was adopted to extract submodels that have different length-width ratios from original discrete facture networks (DFNs). Fluid flow in 1610 DFNs with different geometric characteristics of fractures and length-width ratios was simulated, and the equivalent permeability was calculated. The results show that the average equivalent permeability (KREV) at the REV size for DFNs increases with the increase in Df. The KREV shows a downward trend with increasing length-width ratio of the submodel. A strong exponent functional relationship is found between the REV size and Df. The REV size decreases with increasing Df. With the increment of the length-width ratio of submodels, the REV size shows a decreasing trend. The effects of length-width ratio and Df on the REV size can be negligible when Df≥1.5, but are significant when Df<1.5.

Pulse diagnosis is one of the four diagnostic methods of traditional Chinese medicine. However it suffers from the lack of objective and efficient detection method. We propose a noncontact optical method to detect human wrist pulse, aiming at the precise determination of the temporal and spatial distributions of pulse. The method uses the spatial-carrier digital speckle pattern interferometry (DSPI) to measure the micro/nanoscale skin displacement dynamically. Significant improvements in DSPI measurement have been made to allow the DSPI to detect the comprehensive information of the arterial pulsation at locations of Cun, Guan, and Chi. The experimental results prove that the spatiotemporal distributions of pulse can be obtained by the proposed method. The obtained data can be further used to describe most of the pulse parameters such as rate, rhythm, depth, length, width, and contour.

This research was carried out between the years of 2015-2016 in order todetermine the seed properties of some sunflower genotypes in Erzurum and Iğdır irrigated conditions. In this study seven type of (Coral, P4Ll62, Pactol, Lg5580, Tarsan, 08Tr003, Cadix) sunflower cultivars were used and grain length, width, thickness, dehulled seed (internal rate of grain) and shell ratio of the samples were examined. In this study significant were found the other features except seed width and thickness where some sunflower of grown in different location. In the designed location in Erzurum; grain length, width, thickness, dehulled seed were determined as 11.8–13.4 mm (Coral: P4Ll62), 5.8-6.2 mm (Coral: Lg5580 and Tarsan), 3.5-4.4 mm (Coral and Pactol: Cadix), 16.3-21.3 mm (Cadix: P4Ll62 and Tarsan 1018) and 56.3-76.3 mm (Tarsan and Cadix: P4Ll62). In the designated location in Iğdır, these values ranged between 11.5-14.2 mm (Coral: P4Ll62), 5.5-6.5 mm (Pactol: Tarsan 1018 and Cadix), 3.6-4.1 mm (Coral and Pactol: Cadix), 16.7-26.7mm (P4Ll62 and Pactol: Cadix) and 66.7-81.7 mm (Pactol: Cadix) respectively. According to these results, the designated location for this research in Iğdır come in to prominence in terms of the investigated properties.

Abstract Results obtained in studies can contribute to the advancement of science and innovative methods and techniques for developing practical activities. Reporting conditions that may restrict the implementation of research is critical to ensure the optimal development of further technical studies. The objective of this study was to assess the walking stability of R. dominica on a flat and smooth surface. The study was based on the determination of mortality, morphology and walking stability of the insect outside the grain mass, on a flat and smooth surface. Mortality of adults of this Coleoptera in conditions with and without food was similar, which explains the difficulty that this insect had for accessing the food source on the flat and smooth surface. The measurements of body length (BOL), width (BOW) and height (BOH) of R. dominica were compared with those of Tribolium castaneum (Coleoptera: Tenebrionidae), which showed good ability to walk in these conditions. This study indicated that the former presents lower BOL and BOW, and greater BOH than the second, and all these variables showed differences when analyzed simultaneously by means of the construction of multivariate morphometric indices (Width × Height, Length × Height and Height × Length × Width). These morphometric variables, together with the definition of the geometry most similar to the body shape, resulted in determination of the center of gravity (CG) and static rollover threshold (SRTgeom) for both species. Rhyzopertha dominica and T. castaneum presented CGs considered high and low, respectively, and together with the values obtained for SRTgeom, may justify that R. dominica can be considered a less stable species during movement, and presents greater risk of rollover on flat and smooth surfaces.

The common bean (Phaseolus vulgaris L) is an important food in Mexico that provides both macronutrients and bioactive substances that are beneficial for the health of its consumers, in particular it provides polyphenolic compounds such as anthocyanins that make it a functional food; the objective of the present work was to evaluate the content of polyphenols and their ferric iron reducing activity of beans grown in the Municipality of Hopelchen, Campeche (Mexico) to characterize their agronomic and alimentary value. The morphometric parameters of length, width, thickness, weight and volume were measured; An aqueous maceration of the bean seeds was carried out in an acid medium (0.1 M HCl) and the content of polyphenols (Folin Ciocalteu Method), anthocyanins (visible spectrophotometry) and determination of the Reducing Iron Power (FRAP, by the method of TPTZ) of the aqueous extracts. It was found that the concentration of anthocyanins correlates with the total content of polyphenols and with the reducing activity of the ferric ion, the aqueous extracts obtained had a content of total phenols of 413 mg EAG/100g of seed, of anthocyanins of 42 mg MGE/100 g of seed and an iron reducing power of 10.26 mol of Fe2+/g of seed. The morphometric characteristics and the polyphenol content of the Hopelchén bean demonstrate that the harvested grain is of good quality and corresponds to the expected values for this food.

The article is a synthesis of some studies on the identification of broomrape races originating from China and the determination of the level of intra- and interpopulation variability based on the morphometric parameters of the seeds. The racial status of the analyzed populations was established, also two races of broomrape were identified: race G (Ch1 from Inner Mongolia and Ch3 from HeBei) and race H (Ch2 from Inner Mongolia) using internationally recognized differential Or homosygous lines set. Comparative analyses on the morphometric characteristics of broomrape revealed significant differences in seed Length (Ch1 and Ch3 populations, race G) and Length/width ratio (Ch3 and Ch4), which is an indication of the moderate level of interpopulation variability. In the case of assess of the intrapopulation variability level, the relatively homogeneous (Ch2, Ch3 and Ch4) and relatively heterogeneous (Ch1) populations were identified. According to the coefficient of variation, the population Ch2 identified as H broomrape race has distinguished as the most homogeneous for the investigated biometric indices of the seeds. The moderate positive correlations (between Length and width seed, between seed length and L/w ratio), the strong positive correlations (between Length and L/w ratio) and also the strong negative correlations (between width and L/w ratio) were established. The results obtained through Pearson coefficient revealed the discrimination of populations by region.
