Biochar: Usage, Potential as Alternative to Chemical Fertilizer and Impact of Biochar on Soil-Microbial-Plant Root Interaction

Alemnesh Sisay 1*, Endashaw Girma

Natural resource constraints in the country have severely hampered agricultural production, putting sustainable agriculture and food security in jeopardy. The farmer, through utilizing viable solutions, plays a critical role in ensuring that food needs of a growing human population are met, which has resulted in a greater reliance on chemical fertilizers for higher productivity. It enhances plant growth and energy, hence ensuring global food security; nevertheless, plants cultivated in this technique do not improve good plant characteristics such as root system, shoot system, nutritional features, and will not have enough time to grow and mature appropriately. Chemically generated plants will collect harmful compounds in the human body, which are extremely toxic. The adverse effects of chemical fertilizers will begin not only with their application on soil, but also with their manufacture, which will produce poisonous compounds or gases such as NH4, CO2, and CH4, among others, which will pollute the air. And when industrial pollutants are dumped into neighbouring water bodies without being cleansed, it pollutes the water it also contains the most alarming consequence of chemical waste accumulation in aquatic bodies, namely, water eutrophication. When used continuously in soil, it destroys soil health and quality, resulting in soil contamination. As a result, it is past time to recognize that this food production input is depleting our ecology and environment. As a result, continuing to use it without taking any remedial measures to minimize or judiciously use it will eventually deplete all natural resources and endanger all life on the planet. Only by adopting new agricultural technical techniques, such as transitioning from chemical intensive agriculture to organic inputs such as biochar, manure, and Nano fertilizers, can the negative effects of synthetic chemicals on human health and the environment be mitigated or eliminated. This would increase fertilizer application efficiency as well as use efficiency. Organic farming will help to maintain a healthy natural environment and ecology for current and future generations.

Importance of Error Management in Occupational Safety: A Case Survey Conducted in Manufacturing Set-ups

Skanda Moda Gururajarao

Human failures in workplace may lead to accidents which will affect the individual as well as to the organization. Attribution of human error as the cause of accidents and incidents is common in accident reports. In order to improve the safety aspects of the organization, time and financial resources are being spent. In spite of safety policies, rules and regulations, many accidents, and incidents are being reported from different sectors. The current study focuses on the errors management in medium and small scale manufacturing setups. Authors argue that it is important to view errors as a positive feedback and having a growth mindset towards errors can improve the safety culture thereby improving the overall productivity and efficiency of the organization. Questionnaire on error management culture of the manufacturing setups is prepared and distributed among the medium and small scale industrial operators of the manufacturing setups situated in the Mysore city. Statistical reliability analysis of error management questionnaire is carried out and it is found that instrument is reliable and can be used to assess the error management culture of the organization.

Hadoop Security and Privacy in Big Data

Hadiqa Amjad*, Nimra Jamil, Amna Azeem, and Saba Majeed

Big Data means the large amount of data. Data is rapidly increasing day by day. So, there’s a big issue how to secure the large amount of data. Securing information is become a priority as data is a most important asset in today’s world. In this paper we will discuss the challenges of Hadoop and provide the solutions for securing it. Some security challenges of Hadoop include Data Security, Network Security, Access Control Security etc. We have brief discussed about Hadoop framework, some security management modules and different approaches i.e. Kerberos technique, Bull Eye Algorithm, encryption techniques etc. in securing the Hadoop Ecosystem.
