The 8085 microprocessor is an excellent teaching material to teach basic concepts and programming concepts of a microprocessor. In order to do practice of the microprocessorrelated subjects on LMS (Learning Management System), we have developed the 8085 microprocessor simulator on LMS. In this paper, we describe the development of the 8085 microprocessor simulator on PHP (Personal HomePage), and its implementation on the Moodle-based LMS of our college. © Research India Publications.

Accessing information remotely to dynamically changing information elements cannot be avoided and has become a required functionality for various network services. The fact that most information is dynamic and changes value over time, leads to potential risk of using wrong information by the user due to several factors. The risks of using mismatching of information is more prominent in case of wireless sensor network (WSN) applications as wireless sensor nodes are deployed to collect information which are dynamically changing, say, temperature. Information accessing with minimal mismatch is desired by WSN applications especially when WSN is used for safety and security monitoring purposes. This paper intends to study the impact of information dynamic elements to the information mismatch probability in wireless sensor network. The paper also intends to study how sensitive is the information mismatch probability on dynamic information elements in WSN. © 2015 IEEE. Source

Movement of zinc ions across cellular membranes is achieved mainly by two families of zinc transport genes encoding multi-transmembrane domain proteins. Members of the Zip family generally transport zinc into the cytosol, either from outside the cell or from the lumen of subcellular organelles such as the endoplasmic reticulum, Golgi, endosomes or storage vacuoles. ZnT proteins move zinc in the opposite direction, resulting in efflux from the cell or uptake into organelles. Zinc homeostasis at both the cellular and systemic level is achieved by the coordinated action of numerous Zip and ZnT proteins, twenty-four in mammals and seventeen in the vinegar fly Drosophila melanogaster. Previously, we have identified a zinc toxicity phenotype in the Drosophila eye, caused by targeted over expression of dZip42C.1 (dZip1) combined with knockdown of dZnT63C (dZnT1). In general, this phenotype was rescued by increased zinc efflux or decreased uptake and was exacerbated by decreased efflux or increased uptake. Now we have identified three additional zinc dyshomeostasis phenotypes caused by over expression of dZnT86D, dZnT86DeGFP and dZip71BFLAG. Genetic and dietary manipulation experiments showed that these three phenotypes all differ both from each other and from our original zinc toxicity phenotype. Based on these data and the approximate subcellular localization of each zinc transport protein, we propose that each phenotype represents a different redistribution of zinc within these cells, resulting in a Golgi zinc toxicity, a Golgi zinc deficiency and a combined Golgi/other organelle zinc toxicity respectively. We are able to group the remaining Drosophila Zip and ZnT genes into several functional categories based on their interaction with the three novel zinc dyshomeostasis phenotypes, allowing the role of each zinc transport protein to be defined in greater detail. This research highlights the differential effects that redistribution of zinc can have within a particular tissue and identifies the Golgi as being particularly sensitive to both excess and insufficient zinc. © 2015 Elsevier Ltd.

Ten snake species (Ramphotyphlops braminus, Python bivittatus, Lycodon fasciatus, Lycodon aulicus, Lycodon jara, Rhabdophis subminiatus, Chrysopelea ornata, Dendrelaphis tristis, Naja naja, Trimeresurus albolabris) and two lizards (Gekko gecko and Sphenomorphus maculatus) are reported for the first time from Bhutan. With the exception of a few species, most are from the Sarpang District. Data were collected opportunistically and georeferenced. Copyright © 2010 Centre for Herpetology, Madras Crocodile Bank Trust.

Practices and experiments have important positions at scientific and technological institutions of higher education, because students promote a better understanding of lectures and master practical skills through them. The College of Science and Technology (CST), Royal University of Bhutan (RUB) is the only technical college in Bhutan, and a variety of practices are done at the college. However, the maintenance costs of practical devices or experimental equipment are expensive, and it is difficult to repair them when they have gone wrong. These problems are common in developing countries. Also, these devices or equipment are usable only for practice or experiment hours. Namely, it is impossible for students to use them to prepare or review practices. In order to solve these problems, thus, we have started on the development of simulators which simulate the above-mentioned devices or equipment, and they are implemented on a Learning Management System (LMS). By replacing the devices or equipment to simulators, their maintenance costs will decrease. Also, this makes it possible for students to prepare or review practice by the use of the simulator on the LMS. Here, a variety of equipment is used for practice or experiment. In this paper, we focus on the practice of an 8085 microprocessor. The 8085 microprocessor has a simple architecture and an adequate instruction set. Therefore, the 8085 microprocessor is an excellent teaching material to teach basic concepts and programming of microprocessors, and it is one of the most widely used microprocessor in the subjects of microprocessor in higher education. Really 8085 microprocessor trainers have been being used for the practices of the microprocessor-related subjects at our college. Firstly, we develop the 8085 microprocessor simulator by PHP: Hypertext Pre-processor, because the Moodle-based LMS of our college has been built on PHP. Then, the simulator is implemented on the LMS as an activity module. However, the implementation as an activity module is a lack of portability. When the Moodle-based LMS is updated, for example, it is necessary to modify several forms in the activity module according to the upgraded version of Moodle. Thus, in order to improve the portability, we convert the 8085 microprocessor simulator into a Sharable Content Object Reference Model (SCORM) package by the use of JavaScript. The SCORM package is compared with the above-mentioned activity module. The result shows that the execution speed of the activity module is faster than that of the SCORM package. At present, the cause why the activity module is faster than the SCORM package is under investigation. Source
