A laboratory study was undertaken to determine the N release pattern of Urea Intercalated Biochar derived from Prosopis juliflora. Biochar was produced by pyrolysing the wood cuttings excluding the bark at 350°C. The resultant biochar was characterized using XRD, FT-IR, Raman Spectroscopy and SEM. After characterization, different forms of nitrogen viz., NH4+, NO3−, NH2, Combined NH4+ and NO3− were loaded at varying concentrations (20-200 mM) and sorption and desorption characteristics were examined. Among the forms tested, urea fortified with biochar showed lower desorption at levels of N loading concentration. A new biochar based formulation was evolved by intercalating biochar with urea at 1:1 ratio through hydrothermal method. The intercalated urea: biochar (1:1 ratio) fertilizer was characterised using the set of equipments and the total nitrogen was quantified as 30% as per the EDAX values which closely coincided with analytical values. The retention and release pattern of urea intercalated biochar depicts that the biochar derived PJ is a potential substrate that can be exploited to develop slow release N fertilizer with higher use efficiency and less environmental harzard.Keywords

Allelochemicals released by plants serve as the primary defence by targeting the establishment of weeds and other plants. In this study, 12 different intercrops were assessed over five seasons for total phenol and terpenoid content. A detailed analysis on allelochemi-cals produced was also done using gas chromatog-raphy–mass spectrometry (GC–MS) to correlate with their weed suppression efficiency. Total phenol con-tent of intercrops ranged from 6.5 to 17.6 mg g–1 tissue dry wt, with the highest value in carom followed by sorghum, sunnhemp and marigold. Total terpenoid content of leaf extracts of the intercrops varied from 14.5 to 35.9 μg g–1 tissue dry wt, wherein pearl millet had maximum terpenoid content (35.9 μg g–1 tissue dry wt) followed by sunnhemp and sesame. Analysis using GC–MS indicated the presence of some unique as well as common allelochemicals in the experimental intercrops. To correlate the abundance of these allelo-chemicals released from intercrops with their weed suppression competence, relative neighbour effect (RNE) value was determined for each intercrop. Posi-tive RNE values for sunnhemp, pearl millet and sesame indicate their efficiency in effectively reducing weed population than the other intercrops. Thus, in-tercrops with high phenolic, terpenoid and other alle-lochemicals specific to sunnhemp, pearl millet and sesame can be correlated well with weed suppression as perceptible from their RNE values.Keywords

Titanium (Ti) and Ti-based alloys are the best promising orthopaedic metal transplants. The Young's modulus of Ti and bone are nearer and so Ti implants are known as osseointegrated implants. However, the need for enhancing the osseointegration, corrosion resistance and biocompatibility cannot be ruled out in promoting the Ti as a golden standard. This review describes various surface modifications like acid etching, sand blasting, surface coating, alkali-heat treatment, plasma treatment and ion implantation of Ti-based implants which are the best solutions to promote biocompatibility, osseointegration and ultimately the longevity of implants. In addition, it gives an outline to accomplish the risky task in orthopaedics like recovering skeletal function by replacing the damaged bone for human being survival and it will assist the energetic collaboration of specialists in materials science, chemistry and biology for the quality enhancement.Keywords

Diet plays a crucial role in cancer advancement as well as prevention. Breast cancer is the second leading cause of cancer death among women. Recent research links breast cancer with diet and some evidence for the preventive effect of diet against breast cancer was also documented. The growth of cancer cells is influenced by natural sweetener honey and its multitude of phenolic phytochemical components. Honey has been used medicinally by ancient Greeks and Egyptians and also traditionally exploited in Ayurveda and Chinese medicine. In this paper, the anti-cancer properties of honey and its phytochemical's action against breast cancer have been summarized. They result in apoptosis by enhancing reactive oxygen species level, activating mitochondrial pathway, initiation of pro-apoptotic and anti-apoptotic proteins, induction of p53 pathway that finally cause DNA fragmentation. However, there is a necessity for more proteomic and genetic-based experiments to understand its molecular mechanism to promote honey and its phenolic markers as plausible candidates for breast cancer treatment. Further, there is a need for quality check of honey available in the market, which warrants significant investigation by researchers in the food industry to ensure their attributes.Keywords

Outwardly impeded individuals experience issues in travel and getting to data about open transportation frameworks. A few frameworks have been created for encouraging outwardly hindered utilizing the city transport. Most frameworks give double way correspondence and require expensive and complex hardware. The objective of this work is to decrease the troubles confronted by outwardly debilitated individuals while boarding in city transports, utilizing an intuitive remote correspondence framework. The framework contained a client module and a transport module to give an immediate coordinated association to diminish the existing challenges with a new many-to-numerous correspondence. When the client triggers the switch, the client module promptly conveys the data. In the event that the transport module gets the coordinated flag, it hums and shows the notice in the display to advise the transport driver that somebody is holding up to blind people on the transport. The intelligent remote correspondence help framework is a legitimate and minimal effort gadget for helping outwardly weakened individuals to utilize the city transports.Keywords

The big challenge of the nation is the rising demand for power. The solution is to not just increase investment and enhance power generation, which is a prime need anyways, but invest in more efficient power distribution and optimize power consumption through use of efficient technology. An important component of power consumption worldwide is lightning. India is no different. Global trends in outdoor lighting shows that 18-38% of the total energy bill goes towards outdoor lighting and therefore this is one domain that needs major attention if we look at improving efficiency of power consumption with an objective of saving energy. T5 tube lights with electronic ballast are the best available fluorescent tube light options in the market. A T8 tube light with electromagnetic ballast typically consumes 38W of electricity but a T5 with electronic ballast will consume only 28W of electricity. Thus a T5 provides about 26% electricity saving over a regular T8tubelight. The audit on (68 No’s) T8 tube lights versus T5 tube lights has been done based on the total energy consumption, replacement cost, annual cost saving and payback period.

This paper provides the solution for smart mobility to the people who are unfamiliar with the routes on campus. The proposed automated evehicle contains four wheels - one wheel at the front end and three wheels at the rear end to get a proper balance. It also contains a keyboard Switch with which the user keys their destination point as an input to the system. It is programmed to take the travelers automatically to the destination based on the input provided by the travelers. This is done by automating the main controls like accelerator, brakes and hand bar. Each control is handled by an individual motor. The Servomotor is used to control acceleration whereas the braking and steering of hand bar are controlled by 12V and 24V geared DC motor. Brushless DC motor (BLDC) of rating 48V is used as a main drive. It is responsible for the movement of vehicles. To accomplish zero chance of accident occurrence, ultrasonic sensors are employed. Three numbers of ultrasonic sensors are placed at the front of the vehicle. These sensors help us to detect the obstacle along its way. It gives out a signal when any obstacle is sensed. Global Positioning System (GPS) module helps up to identify the vehicle location on the Earth by coordinates in the form of latitude and longitude. Through this module, the coordinate that the vehicle has to travel is identified and fed into the Arduino microcontroller. At every instance, the present location of the vehicle is compared with the pre-loaded coordinates. Finally, the Arduino microcontroller works with the data from these components and generates the control signals to drive the vehicle in a programmed route. The developed simple Cybernetic E Vehicle is tested in real time.Keywords

Soil compaction is a major physical constraint in cotton production. At present, no information is available on the effects of compaction on the root growth and root anatomy of cotton (Gossypium hirsutum L.). Therefore, we studied the effects of subsoiling (shallow (SSS) and deep (DSS)) and crop rotation (pigeon pea (Cajanus cajan) – cotton (PCR) and radish (Raphanus sativus) – cotton (RCR)) on the root growth of cotton in deep Vertisols during 2017–19. Subsoiling significantly increased the shoot and root length. The root-to-shoot ratio was maximum in DSS (33%), followed by PCR (29%) at the vegetative stage. Scanning electron microscopy analysis of the roots indicated a large number of pores and less contraction of xylem and phloem in the subsoiled and rotation treatments than in the control. Furthermore, the SEM-EDAX spectra indicated a greater abundance of major, secondary and micronutrients in subsoiling and crop rotations compared to the control treatmentFull Text
