This paper presents the idea of internet of things (IOT) innovation to percept data, and talks about the job of the IOT innovation in farming infection and bug nuisance control, which incorporates rural ailment and bug checking framework, gathering sickness and creepy crawly bother data utilizing sensor hubs, information preparing and mining, etc. A malady and bug irritation control framework dependent on IOT is proposed, which comprised of three levels and three frameworks. The framework can give another approach to get to horticultural data for the farm. In this paper a computerized framework has been created to decide if the plant is ordinary or infected. The typical development of the plants, yield and nature of horticultural items is truly influenced by plant illness. This paper attempt to build up a robotized framework that identifies the nearness of disease in the plants. A mechanized ailment recognition framework is created utilizing sensors like temperature, moistness and shading dependent on variety in plant leaf wellbeing condition. The qualities dependent on temperature, mugginess and shading parameters are utilized to distinguish nearness of plant sickness.

Primary user emulator (PUE) attack occurs in Cognitive Radio Networks (CRNs) when a malicious secondary user (SU) poses as a primary user (PU) in order to deprive other legitimate SUs the right to free spectral access for opportunistic communication. In most cases, these legitimate SUs are unable to effectively detect PUEs because the quality of the signals received from a PUE may be severely attenuated by channel fading and/or shadowing. Consequently, in this paper, we have investigated the use of cooperative spectrum sensing (CSS) to improve PUE detection based on a hybrid localization scheme. We considered different pairs of secondary users (SUs) over different received signal strength (RSS) values to evaluate the energy efficiency, accuracy, and speed of the new cooperative scheme. Based on computer simulations, our findings suggest that a PUE can be effectively detected by a pair of SUs with a low Root Mean Square Error rate of 0.0047 even though these SUs may have close RSS values within the same cluster. Furthermore, our scheme performs better in terms of speed, accuracy and low energy consumption rates when compared with other PUE detection schemes. Thus, it is a viable proposition to better detect PUEs in CRNs.

Introduction: Hypocalcemia after thyroid surgery is most important and early complication1. The main aim of this study is to diagnose early hypocalcemia after thyroid surgery and its treatment options Method: 100 patients fulfilling inclusion criteria from December 2018 to February 2021 were included in this study who had undergone thyroid surgery (sub-total, near-total and total). Serum calcium less than 8.1 mg/dl, measured after 24 hours to 48 hours of surgery is taken as hypocalcemia. Following variables are assessed in this study, gender, age, pre-operative serum calcium levels and type of surgery. Hypocalcemia diagnosed by post-operative serum calcium levels, presence of numbness, Chvostek’s sign or Trousseau’s sign noted and analyzed by SPSS v20 was used for statistical analysis. p-value less than 0.05 was considered as statistically significant. Results: Early post-hypocalcemia developed in 71 (71%) patients of them 13(18%) were males and 58 (82%) were females and female gender is significantly more associated with hypocalcemia (p=0.001) Type of surgery (sub-total, near-total and total) is not related to development of early hypocalcemia (p=0.169). Patients who developed early hypocalcemia divided into two groups- A and B respectively. Group A is treated with oral calcium alone and B with oral calcium combined with Vitamin D3. The patients followed up for 6 months. The patients who treated with oral calcium and vitamin D3 combined responded well as compares with oral calcium alone (p=.001). Conclusion: This study suggests that female gender is associated with early hypocalcemia however there is no significant different type of surgery and patients who treated with oral calcium combined with vitamin D3 responded well as compared with oral calcium alone.

Cognitive Radio (CR) is an emerging technology to exploit the existing spectrum dynamically. It can intelligently access the vacant spectrum frequency bands. Although a number of methodologies have been suggested for improving the performance of CR networks, little attention has been given to efficient usage, management and energy efficiency. In this paper, a modern paradigm pertaining to the spectrum allotment and usage, manifested as CR, has been introduced as a potential solution to this problem, where the CR (unlicensed) users can opportunistically deploy the available free licensed spectrum bands in such a way that restricts the degree of interference to the extent that the primary (licensed) users can allow. In this article, we analysis and compare various protocols, in addition, we evaluate CREAM MAC, RMC MAC, SWITCH MAC, EECR MAC protocols related to the CR MAC in term of different parameters such as throughput, data transmission and time efficiency. We conclude the most efficient protocol, which have similar features named as Proposed Efficient Cognitive Radio MAC (PECR-MAC) protocol.
