Abstract:

The yellow mite, Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae), is one of the most serious pests with high polyphagous feeding behavior reported to infest more than 100 different plant species of several greenhouse crops including chilli, jute, ornamental plants and its damage can adversely affect plant morphology and physiology (Grinberg et al., 2005). Their attack is mostly confined to new growth resulting in curling of leaf margins, necrosis of growing points and growth inhibition, which arrests the internodes length and produces suppressed side branches resulting in significant economic losses due to huge yield loss (Karmakar and Mazumdar, 2010). Understanding the availability of resources and effect of organic and inorganic amendments in soil on P. latus population. Documentation of the population abundance, spatial distribution of this pest in chilli and selection of newer management practices would open up new scope for farmers to combat yellow mites in chilli cultivation. Keeping the above facts into consideration effort has been made to review the available literature.

Abstract:

Image processing of rotten, crack, good, sprout and skin damage potatoes for extracting Histogram of Oriented Gradients (HOG) is given that in rotten image, rotten part and the areas subjected to initial sprouting are showing good gradients having cell size 18×18, compared to non defect areas of potato. The smooth areas of histogram of oriented gradients (HOG) may be formed due to not using light diffuser while capturing. HOG of cracked and good potato images observed that gradients are rotating in anti clockwise direction. HOG of skin damage shows that gradients at top of the image are weak than other parts of image but initial sprouting images have high gradients. Similar trend observed for sprout images. Contrast of skin damage potato is higher for sprout, rotten, good and crack potato. Rotten and sprout specimen images are equal in correlation values followed by good and skin damage potato. Crack and sprout specimen images contains equal energy values. Rotten, crack and good specimen images contains equal homogeneity values followed by skin damage and sprout potato.

Keywords: Potatoes, Textural features, HOG.

Abstract:

The global era of information and communication technology (ICT) in academic cannot be over emphasized. Integration of technology in education has shown positive effects on the behavior, attitude, perception, personality, knowledge etc. and some negative effects respectively. The main goal or the philosophy behind this paper is to assess the impact of WhatsApp usage on student academic performance. The paper reviewed enormous works on the research topic in order to make a position on how far WhatsApp has impacted on academic performance. The model adapted in the work indicated a clear relationship between WhatsApp and academic performance. The research methodology was essentially exploratory and therefore depended on secondary data for the examination of issues surrounding WhasApp and academic performance. Content analysis was used to make analysis. The researchers found out that evolution of ICT in the world has led to uncountable effects on education, especially on academic performance. People use social WhatsApp to pass time, for entertainment and learning at large. Many people get socialized through the use of WhatsApp. This avails them the opportunity to share pictures, academic videos, group/class interaction and other vital academic materials online. Also most students tend to spend time on WhatsApp than academic activities. Researches also indicated poor academic communication among students while writing examination. This to us will greatly affect the human capital development on the long run leading to half-baked and unproductive graduates. The researchers therefore, advice that strict rules and regulations should be made to that effect by the various educational institutions towards eliminating this abnormality.

Keywords: WhatsApp Messenger, academic performance, impact and education.
IJTRS-V4-I3-006 :- OPTIMIZATION OF NORMALISING PROCESS PARAMETERS TO ENHANCE MACHINABILITY OF 16MnCr5 STEEL: A STUDY OF MEDIUM SIZED AUTO PARTS INDUSTRY

Abstract:

Low carbon steel such as 16MnCr5 is a widely used grade of steel in the manufacturing industry, especially in automobile industry for manufacturing of gears and shafts due to its favourable properties such as toughness, ductility, high tensile strength, good resistance to corrosion. Heat treatment process such as normalizing is often required to be done on raw material to soften the materials and to relieve the stresses. However, if process parameters are not selected properly, the desirable mechanical properties of steel may not be achieved. The present investigation is an attempt to study the effect of the process parameters such as soaking time, temperature and iso-annealing temperature on the hardness of 16MnCr5 steel using Taguchi method. These were varied and resulting changes in material microstructure were observed. Further, hardness in the range of 160-210BHN and 190-260BHN was observed, with the non uniform distribution of ferrite and pearlite phases. Also, the surface of the samples was found to have coarse grains.
