The first successful plan to build a decentralised digital currency capable of entirely irreversible transactions without the need of a reliable and streamlined third party. The blockchain idea, alongside hash-based verification of-work and public key cryptography, gives an innate component of this decentralization. Indeed, even while blockchain innovation was made to handle the electronic cash twofold spending issue without depending on a confided in outsider, it is likewise being researched and applied to take care of issues in an assortment of different fields. The fundamentals of blockchain, their applications, and challenges are all covered in this article.

Some examinations have reputedly opened doorways to the inclusion of cell phones inside the horticulture sector and in addition a provincial turn of activities. As an example, a record with the aid of Vodafone and Accenture determined that mobile phones for food and horticulture provide powerful answers to producers in accomplishing economic governance, obtaining agricultural information, developing information of records for manufacturing community effectiveness, and in business sectors.

Tribal people believe in superstitions. This paper focuses on superstitious elements in the fictional works of Mamang Dai. Superstitious belief forms a major part of the Adi culture. The researcher has applied cultural studies theory in the following paper. The study of superstition is based on the semiotic study. Correlating sign with the ritual attached. Adi people have a profound faith in natural healing techniques. They share a close relationship with the environment. In fictional works of Mamang Dai, Adi people are often shown practicing traditional healing practices and belief which involve superstition. As the author says in ‘The Legends of Pensam’, “the Adis practice an animistic faith that is woven around forest ecology and co-existence with the natural world.” Superstition and their faith in natural healing are a major part of the Northeastern culture

For the construction purposes of Highrise buildings in Urban Areas or the development of the city and specially for the hilly areas, it is necessary to study all the structural characteristics of soil to make a Durable and Stable structure, as the settlement of soil causes the Failure of the structure. Hence, the testing of soil In situ, OR In laboratory is must, it provides us the study to identify the behaviour of the soil and the soil type. The Geotechnical Properties of soil helps up to define its Shear Strength, Compaction Factor, Water Content, Plastic Limit, Specific Gravity of Soil. It is necessary to check whether the soil is Silting, Claying, Gravel, Peat, Rock or loam in nature without performing any type of soil tests. Soil testing must include assessment of the behaviour of soils in different temperature, moisture condition, loading and stress conditions. So that, the design can act adversely with all the varing possible conditions.

India being an agriculture country, its economy predominantly depends on agriculture yield growth and agro industry products. Any farmer is interested in knowing how much yield he is about to expect. Along with it, percentage of nutrients like Nitrogen (N), Phosphorous (P), and Potassium (K) Location is used along with the use of third-party applications like APIs for weather and temperature, type of soil, nutrient value of the soil in that region, amount of rainfall in the region, soil composition can be determined. All these attributes of data will be analyzed train the data with various suitable machine learning algorithms for creating a model. The system comes with a model to be precise and accurate in predicting crop yield and deliver the end user with proper recommendations about required fertilizer ratio based on atmospheric and soil parameters of the land which enhance to increase the crop yield and increase farmer revenue. Keeping accurate data is an important aspect of agricultural risk management. Propose to use machine-learning techniques to develop a prediction model for crop yield production.

Fiber Reinforced Concrete (FRC) is a composite material consisting of cement based matrix with an ordered or random distribution of fibers that exhibits a synergistic response. In this paper, an experimental investigation on strength of concrete by addition of recron 3s fibers at a dosage of 0-1% by weight of cement has been carried out. Recron 3s acts as "secondary reinforcement" in concrete which arrests shrinkage cracks resistance to impact/abrasion & greatly improves quality of construction. The studies were conducted on M30 mix and tests have been carried out. The compressive strength, split tensile strength, flexural strength, capillary and porosity test of concrete sample was determined and the dosage of fiber varies from 0%, 0.2%, 0.4%, 0.6%, 0.8% and 1%. Finally, the results were compared with the conventional concrete. Keywords— synergistic, Recron 3s fibers, secondary reinforcement, capillary , porosity.

The productivity level of construction industry is mostly depending upon three factors they are labour characteristics, management systems and external issues. Different researchers have determined different factors that influence construction productivity. Understanding the level of productivity, it is important to develop innovative practices to improve construction productivity. This paper includes systematic literature reviews on productivity in construction industry the paper gives an review on different method which are used for measurement of construction productivity, factors affecting and theories on improvement of construction productivity such as labour factor, management factors and external factors, the paper further reviews on the different innovations which are made for improvement in construction productivity. On reviews it is noted that there are lot of different methods and strategies for improvement of construction productivity but they differs from site conditions and the factors which influence construction productivity.

This paper examines the possibility of obtaining the strength of the concrete by the microbiologically induced special growth or filler. Here an attempt was made by using the bacteria “Bacillus subtilis”. Concrete cylinders and prisms were cast with and without addition of bacteria were cast and its split tensile strength and flexural strength were examined. There was an increase in split tensile strength and flexural strength with addition of bacteria. From Scanning Electron Micrography analysis, it is noted that pores were partially filled up by material growth with the addition of the bacteria.
