An identification and classification of herbal plants from its powder using the microscopic image is a challenging task. In this paper, a new approach for identification and classification of Indian herbal plants liquorice, rhubarb and dhatura using the microscopic image is proposed. This paper evaluates the effectiveness of the shape based features with a different classifier for classification of herbal plants. The analysis of microscopic images performed in three stages: Segmentation, Feature Extraction and Classification. To detect the object from the microscopic images we have manually crop the object. For automatic detection of the object, we have applied the Extended Quantum Cut (EQCUT) method of segmentation. After object detection, we have computed the three shape features, including compactness, moments and Fourier descriptors for each object. For evaluating the effectiveness of the shape based features set, various combinations of the three shape features were investigated with support vector machine, K- nearest neighbor and ensemble classifier. Highest classification accuracy of 94.9 % achieved using bagged tree ensemble classifier when Combining all shape features.
Meat and meat products were undergone to adulteration due to its high price and cause many diseases and economic losses for consumers. Fifty samples of minced meat and sausage (25 each) were collected randomly from supermarkets in Assiut city. The samples were subjected to histological and chemical analysis for detection of adulteration. Histologically, adulteration was detected in minced meat and sausage by addition of smooth muscle fibers of hollow organs, heart muscles, spongy bone, thyroid glands, adipose tissue, lung, blood vessels, intestine, proventriculus, ruminant stomach, tendons, cartilage, fascia, nerve trunk, brain, plant tissues include poppy seeds, color additives, cysts and parts of parasites. By ATPase histochemistry, fetal tissue in minced meat and sausage were suspected to add with abundant dark (slow-contracted) muscle fiber than light (fastcontracting) ones. Adulteration of minced meat and sausage with bone tissues was a statistically significant difference (p
Cu2ZnSnS4 (CZTS) thin films were synthesized from subsequently electrochemically deposited Cu/Sn/Zn metal precursors on Mo, Ti and Ta foil substrates by sulfurization at 450 °C for 1 h. Polycrystalline CZTS films with the kesterite structure were formed on each substrate. The lattice parameters of CZTS in films are a = 5.414 ± 0.003 Å, c = 10.85 ± 0.02 Å for Mo substrate, a = 5.415 ± 0.001 Å, c = 10.78 ± 0.01 Å for Ti substrate and a = 5.420 ± 0.003 Å, c = 10.84 ± 0.01 Å for Ta substrate. The CZTS have an average grain sizes of about 53, 80 and 68 nm for Mo, Ti and Ta substrate respectively. The films showed two types of crystallites corresponding to CZTS and CuS phases. The films exhibit Cu-enrichment and the presence of CuS and ZnS secondary phases. Binary sulfides MoS2 and TaS2 were found in the films deposited on Mo and Ta substrates respectively.
