this paper demonstrates design and fabrication o f a mechatronic system for human drowsiness detection. this system can be used in multiple places. for example, in factories, it is used on some dangerous machinery and in cars in order t o prevent the operator o r driver from falling asleep. this system is composed of three parts: (1) mechanical, (2) electrical and (3) image processing system. a...

Drought is a serious problem that causes losses in crop-yield every year, but the mechanisms underlying how roots respond to water deficit are difficult to study under controlled conditions. Methods for assaying root elongation and architecture, especially for seedlings, are commonly achieved on artificial media, such as agar, moistened filter paper, or in hydroponic systems. However, it has be...

Glutathione (GSH) and ascorbate (ASC) are important antioxidants that are involved in stress defence and cell proliferation of meristematic root cells. In principle, synthesis of ASC and GSH in the roots as well as ASC and GSH transport from the shoot to the roots by phloem mass flow is possible. However, it is not yet known whether the ASC and/or the GSH level in roots depends on the supply fr...

Ground penetrating radar (GPR), as a newly nondestructive testing technology (NDT), has been adopted to explore the spatial position and structure of tree roots. Due complexity soil distribution randomness root in natural environment, it is difficult locate GPR B-Scan image. In this study, novel method for detection B-scan image by considering both multidirectional features symmetry hyperbola w...

conclusions: detailed information about root fractures may be obtained using cbct. results: according to the fracture types and fracture presence, there was an overall statistically significant agreement between the key and readings. kappa values for intra observer agreement ranged between 0.705 and 0.804 indicating that each observer gave acceptable ratings for the type and presence of fractur...

A thorough knowledge about the normal and abnormal variation of anatomy of the teeth and their detection is essential for clinical success. Maxillary fi rst premolars show a considerable variation in root canal morphology but the presence of three roots is rare. However, it must be taken considered radiographically and clinically during endodontic treatment. This article describes the diagnosis...

Multicellular organisms possess a diverse array of cell types, which vary in size, shape, composition, and function. Therefore, a fundamental feature of development in multicellular organisms is the proper specification and differentiation of distinct cell types. In plants, the formation of hair cells in the root epidermis has been employed for more than a century as a simple model for studies ...

Obligate symbiotic fungi that form arbuscular mycorrhizae (AMF; belonging to the Glomeromycota phylum) are some of the most important soil microorganisms. AMFs facilitate mineral nutrient uptake from the soil, in exchange for plant-assimilated carbon, and promote water-stress tolerance and resistance to certain diseases. AMFs colonize the root by producing inter- and intra-cellular hyphae. When...

In this paper, we propose a hybrid approach for designing Intrusion Detection Systems. This approach is based on a Fuzzy Genetic Machine Learning Algorithm to generate fuzzy rules. The rules are able to solve the classification problem in designing an anomaly IDS. The proposed approach supports multiple attack classification. It means that, it is able to detect five classes consist of Denial of...

Results of the analyses of occupational and environmental samples are frequently reported as "less than a specified value," a practice followed by many analytical laboratories. A left-censored distribution occurs when analytical laboratories do not report results that fall below their limits of detection or quantification. Approximately 37% of the household interior dust lead loadings collected...
