Biometric Pulse Counting System using Microcontroller 8051

ABSTRACT: This paper gives a novel idea about the design and implementation of a microcontroller based pulse counter. Intel 8051 is used as the main microcontroller unit and the system has been fabricated to count the total number of pulse in a minute. IR sensors are connected as the input sensors which read the blood flow through the fingers. The microcontroller counts the number of input signals and thus generates an output on a display window build using three 7 segment IC. This system is highly efficient, accurate and economical and thus can be effectively used as an instrument to measure pulse on medical grounds

Reviewing and Analysing Phytochemical Phyto-pharmacological and Therapeutic Potential of Hebs Againsts Anti Nociceptive Activity and Pain Management

Therapeutic plants are generally utilized include overall as pain relieving and for treatment appropriate to   fiery messes.

Restorative plants are acquiring notoriety among populace because appropriate to   minimal expense and best viability. Torment is side effect appropriate to   different diseases and medications that remember torment is a subject appropriate to   drug research. Objective appropriate to   this article is towards archive plants having against nociceptive exercises. Material for this audit was taken generally from reading material and electronic diary Up towards date.  Towards gather distribution PubMed, Google researchers and Cochrane information base appropriate to   efficient audits was utilized

Plant Parasitic Nematodes and Their Management in Crop Production: a Review

Plant Parasitic Nematodes are small worm like transparent, bilateral symmetry, pseudocoelomate, multicellular, free living or parasitic microorganism which are predatory, aquatic, terrestrial, entopathogenic, ectoparasite, endoparasite, semi-endoparasite or sedentary. They cause substantial problems to major crops throughout the world, including vegetables, fruits, and grain crops. The root knot and cyst nematodes are economically important pests in numerous crops. Crop damage from nematodes is not readily apparent in most cases, and it often remains hidden by the many other factors limiting plant growth. In the past, the control of the nematodes has been based on the synthetic nematicides, the number of which has been drastically restricted in the EU because of their environmental side effects and subsequent restriction in European Union (EU) rules and regulations. Many other methods like cultural control, biological control, use of biotechnological tools and methods, use of resistant cultivars are tested and proven successful in controlling different species of nematodes all over the world. Alternatively, combinations of the different methods are proven to be highly effective both economically and environmentally

Synthesis of new glassy Mg-Ca-Zn alloys with exceptionally low Young's Modulus: Exploring near eutectic compositions

We report two new magnesium-rich glassy Mg-Ca-Zn alloys of one eutectic (Mg72Ca12Zn16) and another near eutectic (Mg63Ca15Zn22) composition. The glass-forming ability of the alloys is slightly lower than that of the Mg60Ca5Zn35 alloy which has been well explored earlier. The Young's Modulus of the new glassy alloys is exceptionally low (similar to 35 GPa) and much lower than that of the Mg(60)Ca(5)Zn(35)glassy alloy (similar to 50 GPa) indicating possible potential biomedical applications.

Desert locust (Schistocerca gregaria Forskal) and its management: A review

The desert locust, Schistocerca gregaria (Forskal) (Orthoptera: Acrididae), is the world’s most dangerous and destructive migratory pest. It is a highly voracious and polyphagous insect. Its swarms can migrate hundreds of kilometers per day and invade areas covering millions of square kilometers, causing significant and widespread crop losses. In this review, we synthesize published research and reports on the life cycle, behavior, phases of desert locust along with its damage and management. Elements of locust management include population monitoring and population prediction. However, there are difficulties involved with estimating locust populations because locust swarms are highly mobile. Control techniques for managing locust swarms include cultural control (digging, burning), baiting (scattering locust food impregnated with insecticides), dusting with insecticide, and spraying liquid insecticides (chemical or biological) using ultra-low volume (ULV) application. Effective management strategy relies on improved knowledge of pest biology, more efficient monitoring and control techniques
