 Abstract

In present investigation pulping of Anthocephalus indicus (kadam) were carried out using 12 and 14, % active alkali and pulps produced corresponding to kappa number 36.49 and 24.76 were treated with oxygen at 8 kg/cm2 oxygen pressure. At pressure, treatment was given 100oC and 110oC temperature for 60 minutes using 1.00 and 2.00 % alkali charge. Unbleached and pulps subjected to delignification by oxygen under alkaline conditions under pressure the residual and removed lignins were treated with nitrobenzene oxidation and the products was analysed by high performance liquid chromatography (HPLC). Compound like P-hydroxy benzoic acid, Vanillic acid, Syringic acid, p-hydroxybenzaldehyde, vanillin, Syringaldehyde, Acetovanillone, Acetosyringone was identified. The effect of oxygen treatment with different temperature and alkali charge on compound like vanillin, Syringaldehyde and Vanillic acid was analysed in adequate length of paper.

 Abstract

Smartphones is an outstanding scientific invention and this magical device is an integral part of our daily life. The coronavirus disease 2019 (COVID-19) pandemic occurred in a time of this scientific progress and global digitalization; where smart phones become ubiquitous in our lives from education to clinical consultation. It helps us to stay connected with our family, friends, loved ones and society as well in variety of ways including: calling, Text/Messages, E-mail, video calling, public or social media. The various applications and components on a handset including gaming, social networking, electronic mailing, online payment, barcode scanning, calculators, weather report, text messages, Bluetooth, camera, MMS messaging, MP3 player and GPS have made users more and more tech informative. Offering an immense advantage to the public including learners, it has also spread its negative effects. There are some social, psychological and health effects of mobile phone users. The higher rates of mobile application usage by teachers and students significantly affected the self-regulation of behaviour, imposed negative aspects on meta-cognation and cognitive learning. This paper tries to explore impact of smart phone usage in learning and its effect among students as well. Moreover, it will look in the social, physiological, psychological, environmental effects among the students and describes strategies to be adopted to manage this.

 Abstract

Water and air the two essential components which serve as the soul of all life forms; have become global garbage cans. Synthetic polymers are vital to many branches of industries for example in packaging industry, Manufacturing industry, Automobile industry etc. Though they are essential element in the cycle, but the fact that Plastic are harmful cannot be denied, especially because of its non-biodegradable nature. When we litter it on soil it makes the soil less fertile, it also harms the sea life , burning of plastics leads to environmental pollution owing to release of poisonous chemicals. Growth is persistent , so is the need of polymers, increasing day by day therefore unlike synthetic polymers that are derived from petroleum oil a better, optimized and efficient substitute would be bio-plastics produced from renewable biomass sources such as plant residue and extracts, agricultural by-products organic minerals to decrease the burden of pollution. This paper discusses cause and affect relations of synthetic polymers on human race as well on marine life further a brief on bio-plastics as an efficient alternate

 Abstract

This paper discusses the role, importance and challenges of ICT in teaching learning process in the 21st century. Information and communication technologies at present are influencing every aspect of human life. ICT is described as the whole range of process of generation, storage, transmission, retrieval and processing of information. It helps in breaking the walls of time distance and speed in the educational set up. ICT as the technology used to manage information and aid communication. It offers learners more complete and individual control over their learning. Moreover, many people recognize ICTs as catalysts for change, handling and exchanging information, teaching strategies, teaching methods, learning approaches, scientific research, and in accessing information. The effective integration of this technology into classroom practices poses a challenge to teachers and administrators. Improving the quality of education and training particularly at a time of educational expansion, ICT enhance to quality of education by increasing learners motivation and engagement, by facilitating the acquisition of basic skills, and enhancing teacher training. The papers examine the importance, role and challenges of ICT in the contemporary society.

 Abstract

Choice of water sources is a broad and complex phenomenon. It is not even a stable one but may change on a daily or seasonal basis. Several factors influence choice of water sources. Even though people to a large extent seem to follow routines, there are constraints and opportunities that can break such patterns. Lack of money can therefore force people to use normally water from spring (tuikhur), public taps, and hand pumps. Most of the low income families are determined by more than one factors as far as their choice of water source is concerned.

 Abstract

Water Resources and Agriculture in north Bihar is base of economy. Irrigation scheduling many researchers have attempted to find out the lower limit of available water in the assumed shallow root-zones of crops at which the irrigation must be applied to avoid yield reduction. Though this approach is still prevalent, but it suffers from a few serious drawbacks. Firstly, the assumption of a fixed root-zone runs counter to the dynamic and ever deepening character of crop roots during the greater part of the growing period. Secondly, the periodical determinations of root-growth and soil-water depletion are beyond the know-how and means of the common farmers. Whatever short comings are in this approach, it helped in fixing irrigation schedule earlier. The sowing time available water storage achieved through heavy pre-sowing irrigation which is a common practice is an insurance against the irrigation-deficits during the growing period. The irrigation depth for post-sowing watering depends upon the water storage deficit of the root-zone which is determined by the time-interval between irrigation and ET demand.
