The illegal movement of valuable trees such as sandal wood trees in forests poses a severe risk to natural reserves and it instigates a great loss to our country’s wealth. Almost 24,000 square miles has been lost due to deforestation in the past decade. This paper proposes an antipoaching system using NodeMCU based wireless system that uses 3- axis MEMS accelerometer (GY-61) and tilt sensor for detecting the falling of trees due to cutting of trees or natural calamities and Flame sensor, fire retardant for detecting and controlling the fire. In this project we use NodeMCU which has an inbuilt Wi-Fi module which covers a distance of around 300m range, is used in this project for cost efficiency and also NodeMCU enables the communication with neighbor nodes like client and server nodes. This protocol is used to monitor the trees even using a single node from the server system. The solenoid valve is used to spray the fire retardant to control the fire. Some IOT modules can also be used in this system to provide accurate information and remote monitoring of trees.

Industries play an important role in the economic growth of any nation, whereas they release pollutants, which impact our environment seriously. Owing to the rapid climate change and global warming, our earth is searching for different sustainable energy technologies. Microbial fuel cell technology is emerging as one of the most versatile sustainable energy technology, with their ability to tap the energy stored in the wastewater and convert it directly into electrical energy. Though MFC research is still in its nascent stage, its theoretical superiority makes it a unique technology, which can be developed into a self‐sufficient system for wastewater treatment in the near future. Brewery industries consume large quantities of water for beer production and hence release large quantities of wastewater. The chemical energy stored in the brewery wastewater could be converted into useful bioelectricity by MFC technology compared to other traditional wastewater treatment technologies, which are all energy intensive. Brewery wastewater, rich in biodegradable organic matter with their non‐toxic nature, makes it a highly suitable substrate for MFC. It is one of the few substrates that have made it to pilot‐scale studies worldwide. This study aims to review the microbial fuel cells with brewery wastewater as their substrate. It will elaborate the different configurations of MFCs employed for brewery wastewater so far, their power producing ability and wastewater treatment efficiency. The critical factors that influence these MFC systems will also be discussed. Finally, this article also identifies and suggests different strategies to improve the performance of such MFC systems.

The medical record system includes substantial information such as diagnoses of diseases, treatment undergone, patient's health condition, medication information, examination results and nursing actions. Consequently, these information helps medical staff understand the patient's medical record instantly and can provide accurate diagnoses for the disease. Traditional paper based medical report system has many problems including illegible handwriting, conversation difficulty, slow data transfer, easily damaged and rampant. To overcome such drawbacks, we reformed it into electronic patient records. With the increased development of internet, sharing the medical reports over a public domain is not much secured that it can be accessed by attackers and destroy them. To protect these information from attackers, existing system provides access control through Lagrange Interpolation in which the key we use is randomized, no relationship between each key so that the key can be managed effectively. To provide access control and to enhance security Elliptic Curve Cryptography was used in which the attackers encounter Elliptic Curve Discrete Logarithmic Problem. Once the prime number is big enough, attackers will have trouble deciphering the key but it increases the size of the encrypted message, is difficult, increases implementation errors and not much secured too. So that, we proposed DNA sequencing which ensures secured data authorization, storage and transmission.

Background: Uncontrolled stress can be made at ease through resilient emotions and higher coping skills. The study aimed at assessing the level of stress, resilience, and coping among medical students and to study the effect of stress intervention programs on the stress level. Materials and Methods: This was a nonrandomized control trial among 526 medical students which used medical student stress questionnaire, and perceive stress scale (PSS), resilience assessment using a 25-item resilience scale, and coping using a modified Pareekh scale. After the completion of the preintervention assessment, the students were assigned nonrandomly into two groups (intervention group n = 272 vs. nonintervention group n = 254), and the stress intervention programs were done for one group without any programs for the other group. Results: The study concluded that 246 (46.8%), 274 (52.1%), and 277 (52.7%) showed higher stress higher resilience and lower coping, respectively. The study showed that, with stress intervention programs, stress levels by PSS got significantly reduced by 2.64 scores. Conclusions: The study showed the presence of higher stress and resilience and lower coping among medical students. The inclusion of programs to reduce the stress among students showed a positive result and can be replicated.
