 Abstract

Azetidinone is a saturated form of nitrogen containing cyclobutane having carbonyl group. It has been considered as a versatile nucleus which possess almost all types of biological activities mainly antimicrobial and antifungal activity. This diversity in the biological response profile has attracted the attention of many researchers to explore this skeleton to its multiple potential against several activities. The present review article explains the chemistry, synthesis and various biological activities of azetidinones.

Abstract :The purpose of the present study was to find out significant differences in the study habits of secondary school students of high and low level of maternal education. Study Habit Inventory (Hindi Version) constructed by Dr. B.V.Patel(1975) was administered on 200 secondary school students to collect relevant data. The data so collected was analysed statistically by employing Mean, S.D., and t-test. The finding revealed that significant difference exists between secondary school students with high and low level of maternal education on the home environment and planning of work component of study habits. There is be no significant difference in the secondary school students with high level of maternal education and low level of maternal education on the following components of study-habits namely; reading and note taking, concentration, preparation of the exam, habits and interests, school environment and total study habits. Secondary school students with high level of maternal education are better on home environment & planning of work and planning of subjects components of study habits than their counterparts with low level of maternal education. Secondary school students belonging to high level of maternal education and low level of maternal education are by and large similar on reading and note taking, concentration, preparation of the exam, habits and interests, school environment and total study habits.

 Abstract

Pisum sativum L. (Garden pea) is an annual crop of immense importance. In India it is cultivated in an area of more than 280.0 thousand hactares with annual production of more than 4.0 million tonnes but its yield decline heavily due to powdery mildew a fungal disease caused by Erysiphae pisi, E. polygoni; E. cichoracearum etc. Severe infection reduces plant growth seed weight, seeds per pod and pod number. Pod infection causes seed discoloration leading to downgrading its quality. Management using fungicides; most commonly triadimefon is in regular practice, but they only protect uninfected foliage and have limited systemic activity. Over time, the fungicides accumulate at the leaf margins, leaving other parts of the leaf more open to infection which also has hazardous effect on the environment. One of the effective methods for controlling fungal infection may be the introduction of rice chitinase into the sensitive but otherwise high yielding crops. Large number of genetic transformation procedures are available using both direct i.e. biolistic or gene gun or particle bombardment or in-direct i.e. Agrobacterium mediated for constitutive expression of introduced chitinase gene. Upon standardization of efficient shoot regeneration and transformation system in pea, transgenic plants may produced against these fungi leading to reduced yield loss in this economically valued crop. The functional validation of chitinase in pea will show way for its effective utilization in future for reducing loss caused due to several fungi.

EVALUATION OF SECONDARY METABOLITES FROM SOME MEDICINAL PLANTS BY SPECTROPHOTOMETRIC METHOD Bharat Raghunath Nagare1 and Rahul Dilip Jawale2 1 Shri Shivaji Arts, Commerce and Science College, Akot, 444101, (MS) India. bharatnagare2010@gmail.com 2 Govt.Vidarbha Institute of Science and Humanities, Amravati, 444604, (MS) India. Abstract: This study mainly focused on evaluation or quantification of secondary metabolites by spectrophotometric method. Plant extract was prepared in alcoholic extract for quantification. Quantitative analysis was performed with the help of UV-vis spectrophotometer. The highest quantity of secondary metabolites was found in Barleria prionitis than Ceasalpinia bonduc and Leonotis nepetifolia. The highest amount of total phenol, ortho-dihydric phenol, tannin, and leuco-anthocyanin in Barleria prionitis was found 10 �g/gm, 9.5 �g /gm, 1.6 �g /gm and 0.055 �g /gm respectively. While Caesalpinia bonduc showed highest amount of anthocyanin (0.0325 �g /gm) than that of Barleria prionitis and Leonotis nepetifolia. Quantity of flavanol is high in Leonotis nepetifolia (0.86 �g /gm). It was concluded that Barlelia prionitis having more secondary metabolites which gives medicinal property to plant and may use as a traditional medicine.

 Abstract

This research presents the processes involved in Multiclass SVM and SIFT algorithms. Support Vector Machines (SVM) is a popular method in the machine learning area for binary classification problems. Multi-class SVM usually implemented by combining several binary SVMs. The scale-invariant feature transform is also used as a feature detection algorithm. This method transforms an image into a great collection of feature vectors, every vector is invariant to image translation, rotation, and scaling, partially invariant to illumination changes and forceful to local geometric distortion. In this research key points are identified with the SIFT algorithm and also multiclass SVM classifier is implemented to identify the percentage of area affected in the diseased image.

 Abstract

Modifications of construction materials have an important bearing on the building sector. Several attempts have been therefore made in the building material industry to put to use waste material products, e.g., worn-out tyres, into useful and cost-effective items. Success in this regard will contribute to the reduction of waste material dumping problems by utilizing the waste materials as raw material for other products. The present proposal involves a comprehensive laboratory study for the newer application of this waste material in the preparation of fibrous concrete. The primary objective of investigation is to study the strength behavior i.e. compressive and flexural strength of rubberized concrete with different volume of crumb rubber. The proposed work is aimed to study the effect of volume variation of crumb rubber on the compressive strength &flexural strength.

Field experiments were conducted for two years to determine the effect of silkworm rearing waste on growth and yield of mulberry plants and silkworm growth and economic traits. Methodology: This study consisted of 11 treatments including absolute control with 3 replications. Results of this study: silkworm excreta alone 400 gm per plant recorded the longest shoot, greater number of branches, more number of leaves, highest 100 leaf weight and highest leaf yield. The silkworm excreta alone 400 gm per plant had a significant and positive influence on larval and cocoon parameters which recorded the highest values of larval weight, single cocoon weight, shell ratio, single cocoon filament length and denier.

 Abstract

From past decades the world is undergoing a extreme rapid transformation from isolated systems to Internet based enabled things capable of interacting with each other and after analysing this data extracting valuable information. Due to Internet of things there are creation of new connecting devices, which have implemented smart cities, smart homes etc. With this new approach of Internet of things it contains new kind of challenges from a security and privacy perspective. In this paper, we present major security issues for IOT.
