Research ArticleOpen accessIn the keywordsMicroscopic Study of the Lungs of Sprague-Dawley Rats from Various Ages of Postnatal and Aging PeriodsRia Margiana, Isabella Kurnia Liem, Jeanne Adiwinata PawitanPhysiological changes in postnatal and aging lung are associated with a variety of microscopic changes in the lung, especially the alveolar lung tissue, both in the interstitial and epithelial component. Interstitial tissue of the lung will increase in thickness that is supposed to be due to changes in fiber composition, particularly collagen. However, the exact changes are still under debate … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 13 Jun 2015 · 7,312 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIMPLEMENTATION AND EVALUATION OF IMAGE PROCESSING TECHNIQUES ON A VISION NAVIGATION LINE FOLLOWER ROBOTWalaa E. Elhady, Heba A. Elnemr, Gamal SelimIn a fast growing industrial world, carriers are required to carry products from one manufacturing plant to another which are usually in different buildings or separate blocks. This study intends to automate this sector using vision controlled mobile robots instead of laying railway tracks which are both expensive and inconvenient. To achieve this purpose an autonomous robot with computer vision … …Journal of Computer Science, Vol. 10, Issue 6 · 1 Feb 2014 · 7,746 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Alternative Graph Cut Algorithm for Morphological Edge DetectionP. RadhakrishnanProblem statement: Image analysis has some basic importance of edge detection. Characterize the object boundaries are helpful for object segmentation, registration and identification in a scene. There are many methods for edge detection, but it can be identified by two major methods, search-based and zero-crossing based. Approach: Proposed method tries to follow searching the edge points by applying graph cuts … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 29 May 2012 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Linear Model for Moving Measurements Estimation in Urban Climate StudiesClaudia Cotrim Pezzuto, Lucila Chebel Labaki, Lia Toledo Moreira Mota, Alexandre Alexandre de Assis MotaProblem statement: Several methods can be adopted to study the variations in urban climate. The mobile measurement method is one of them, involving information provided by moving measurements of air temperature, that are taken in points defined along pre-established routes and also data from fixed-point temperature recording stations. Because moving measurements are made in different times along the measurement process, … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,038 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFat Body Cells of Gynes and Queens of Four Species of Fungus Growing Ants (Hymenoptera: Formicidae: Attini); Relationship with the VitellogenesisG. C. Roma, M. I. Camargo-Mathias, O. C. BuenoThe morphometric analysis of fat body cells of gynes of Cyphomyrmex rimosus and Mycetarotes parallelus and queens of Acromyrmex disciger and Atta laevigata revealed significant differences in area of parietal and perivisceral trophocytes in all studied species. This was also observed for parietal and perivisceral oenocytes. No differences, however, were observed when the areas of oenocytes of gynes are compared. … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 3 · 30 Sep 2006 · 7,781 accessesView PDFCite
Research ArticleOpen accessIn the keywordsObject Detection using Circular Hough TransformMohamed Rizon, Haniza Yazid, Puteh Saad et al.In this study we propose a new system to detect the object from an input image. The proposed system first uses the separability filter proposed by Fukui and Yamaguchi (Trans. IEICE Japan J80-D-II. 8, 2170-2177, 1997) to obtain the best object candidates and next, the system uses the Circular Hough Transform (CHT) to detect the presence of circular shape. The … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 8,216 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCharacterization of Reconstructed Basins Using Pattern Spectrum ProcedureP. RadhakrishnanSeveral classical and Fractal binary shapes, which are akin to geophysical shapes such as basins, lakes, and pore-grain spruce, are analyzed and characterized by employing various mathematical morphological transformations, and methods. By employing rhombus, square and octagon structuring elements, these shapes are decomposed into their skeletal networks and their corresponding skeletal network subsets are dilated to the respective degree by … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Pseudomonas aeruginosa Infecting Bacteriophages from Swiftlet House Pond Water and Sewage in South Kalimantan, IndonesiaSiti Gusti Ningrum, Dyah Widhowati, Titin Yulinery et al.Pseudomonas aeruginosa is an opportunistic bacterium that may occur in animal-production environments and contribute to microbial contamination of animal-derived products. However, information on P. aeruginosa-infecting bacteriophages in artificial swiftlet-house environments remains limited. This study aimed to isolate and evaluate P. aeruginosa-infecting bacteriophages from the swiftlet-house environment in South Kalimantan, Indonesia. A total of 75 samples involving pond waters (n = … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 55 accessesView PDFCite
Research ArticleOpen accessIn the abstractMarine-Derived Extracts as Economically Sustainable and Ethical Alternatives to Fetal Bovine Serum in HEK293 Cell CultureKian Kenneth Francisco Sanchez, Jennifer Seki-Wong et al.Fetal Bovine Serum (FBS) is a staple supplement in cell culture, providing key growth factors that promote cell health and proliferation. Since 1885, cell culture has been a cornerstone of both basic and applied research, leading to significant discoveries of cell communication and function. However, the use of FBS presents economic and ethical challenges. Millions of bovine fetuses are euthanized … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 7 Aug 2026 · 1,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractInheritance of Leaf Characters in Sweet Potato (Ipomoea batatas [L.] Lam.)Alfredo Morales, Dania RodríguezThis study aimed to establish foundational knowledge regarding the inheritance patterns of two foliar traits (leaf morphology and midrib pigmentation) in Ipomoea batatas. To overcome the challenges associated with discretely classifying color and shape frequencies, five morphometric descriptors were employed. Two of these parameters addressed leaf shape (Circularity and Aspect Ratio), while three characterized the color of the central vein … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 3 Jul 2026 · 1,409 accessesView PDFCite
