At the research farm of Central Institute of Agricultural Engineering, Bhopal, India experimental trials were conducted during three rainy seasons (June-October) starting with 2016-2017. In this study red, white, black and green colors shade nets with varying shade intensities (35, 50 and 75 %) were studied by constructing each shadenet of 100 m² size. All the tomato crop growth parameters significantly varied with shade net colours and intensities. Crop under red coloured shadenet house was found to have highest plant height and more branches over crop cultivation in other coloured net houses. Among the shade intensifies crop under 50% had highest plant height and more branches per plant as compared to crop under other intensities. Tomato crop under 50% shade intensity with red color shade net gave highest yield and the lowest yield was observed in 75% green colured shadenet house. Reduction in average ambient temperatures over control (outside the shadenet house, which was 30 °C) in different shadenets are 3.2-5.9 °C under black shade net, 1.4-3.5 °C under green, 3.0 -5.3 °C under white, 2.0 – 4.4 °C under red coloured shade net house Average light intensity under ambient conditions was highest with 1,10,000 lux whereas in shade net houses the light intensities are much lower than the ambient conditions. The light intensities were found to be highest in green coloured net house for all intensities followed by red, white and black coloured net houses. [ABSTRACT FROM AUTHOR]

There is no doubt in our minds that today's individuals are very busy and stressed out at work, and they do not have much time to shop in stores for long periods of time. Shopping for one's own needs is frequently out of the question for working-class individuals and students who are enrolled in higher education programmers. Online shopping has therefore been established in the market for those customers who like to purchase online. The purpose of this study is to investigate the numerous factors that impact a customer's choice to purchase online. This study examines the internet buying patterns of clients of different ages. For online buying, it's important to consider factors like a customer's ethnicity or marital status and the kind of job they have as well as their annual income. Customers' reasons for not making online purchases may also be discovered via this study. There were 100 participants in this research, with the majority of them falling into one of three age categories: adolescents, adults, or the elderly. [ABSTRACT FROM AUTHOR]

A study was conducted during 2010-2015 at Central Institute of Agricultural Engineering, Bhopal, to find out effect of irrigation and fertigation scheduling on growth, yield and quality of guava (Psidium guajava ). The experiments were laid out in factorial randomized block design with six treatment combinations which include three irrigation level (100, 80 and 60 %) along with two fertigation level (100 and 75 % water soluble fertilizers) and replicated thrice. The nitrogen, phosphorus and potassium fertilizers were applied through fertigation as well as soil application to test various attributes of five six old guava cv. L-49. The investigation indicated that the maximum plant height, Periphery of rootstock, yield per plant (kg/plant) and yield (t/ha) were higher under D1F1 (100 % irrigation with 100 % fertigation) followed by D2F1 (80 % irrigation with 100 % fertigation) and minimum under D3F2 (60 % irrigation with 75 % fertigation). Interaction effect was non-significant at 0.05 % level due to plant height (3.90 m) and Periphery of rootstock (26.26 cm) but significantly influenced by yield per plant (27.65 kg/plant) and yield (7.65 t/ha). Physico-chemical properties like fruit diameter (6.76 cm), fruit weight (182.10 g) and pulp weight (134.38 g) were significantly at 0.05 % due to different irrigation and fertigation level as well as interaction effects but fruit length (7.45 cm), TSS (13.22 %) and ascorbic acid (54.32 mg/100 g pulp) were non-significant due to different level of irrigation and fertigation as well as interaction effect.

Thin layer chromatography in combination with spectrophotometry and titrimetry has been used to evaluate chromatographic characteristics of bauxite constituents. The retention behaviors of four major constituents (Al3+, Fe2+, Ti4+, Si4+) in bauxite mineral have been examined on plain and modified layers of silica gel G, silica gel H and cellulose with mobile phases containing aqueous sodium chloride, formic acid and hydrochloric acid. Ternary separation of Al-Fe-Ti was achieved on chromatographic plates made of silica gel H. The pH effect and presence of impurity elements in samples, nature of stationary phases on the ternary separation and detection limits of bauxite constituents were studied. Silicon in bauxite was detected on cellulose plates. Quantitative determinations of Al3+, Fe2+ and Ti4+ on silica gel H impregnated with sodium formate layers were achieved by titrimetry and spectrophotometry.

Acetylcholinesterase (AChE) activity and acetylcholine (ACh) content of muscle, gill, liver and brain tissues of control and methyl parathion-exposed (MPE) fish were determined. In addition, in vitro concentrations of eserine necessary to produce inhibition of AChE equivalent to in vivo inhibition by sublethal amounts of methyl parathion (MP) were also investigated. AChE activity decreased in all tissues, while ACh content showed a corresponding increase. These observations indicate disruption of nerve impulse conduction. The in vitro effect of eserine on AChE activity differed with the type of MP action. These results are discussed in relation to the sensitivity and extent of innervation of various tissues.

The levels of total lipids, phospholipids, free fatty acids and total cholesterol were studied in selected tissues of the fish, Oreochromis mossambicus under sublethal stress of methyl parathion for 48 h. The levels of total lipids and phospholipids decreased while the free fatty acids and total cholesterol levels increased during the exposure period. These results are discussed in relation to induced gluconeogenesis and the diversion of acetyl CoA to cholesterol synthesis during methyl parathion intoxication.

400 adult unrelated individuals of both sexes were studied from two groups of Srivaishnava Brahmins residing in Tirupati, South India, for the distribution of middle phalangeal hair (MPH). The occurrence of MPH was predominantly manifested on the III, IV, and V digits of both hands in the two sexes of Vadagalai and Tengalai groups. Tengalai males showed higher frequency of presence of MPH (39.00%) than Vadagalai males (37.00%). Among the females the frequency was (36.00 %) in Tengalai and (34.00 %) in Vadagalai groups. Sex differences were not statistically significant in both the groups. Populations of Mongoloid affinity seems to have a marked increase in the frequency of individuals without MPH and the present Srivaishnava Brahmin sample reflects such a similar tendency.

Exposure of fish to a sublethal concentration of malathion showed a significant inhibition of acetylcholinesterase (AChE) activity. The levels of protease were markedly elevated with a consequent increase in most of the free amino acids. However, the levels of glutamic acid and valine, phenylalanine and methionine complex remained unchanged, while aspartic acid showed a marked drop. These changes are discussed in relation to the sublethal stress induced by malathion.

The activity levels of aspartate aminotransferase (AAT), alanine aminotransferase (AlAT) and total adenosine triphosphatase (ATPase) were studied in muscle, gill, liver and brain tissues of control and methyl parathion exposed (MPE) fish. Both aminotransferases were elevated in all the tissues inferring the diversion of alpha-amino acids into the TCA cycle as keto acids to augment energy production during methyl parathion (MP) stress. In gill, liver and brain tissues, there seemed to be a shift in the aminotransferase reactions under MP impact. The total ATPase activity was decreased in all tissues, suggesting inhibition of active transport and oxidative phosphorylation.

Kinetic parameters of aldolases in muscle, gill, liver and brain tissues of the teleost Tilapia mossambica were studied at sublethal concentrations with methyl parathion (MP). The pH activity profiles were optimal at pH 7.0 and 9.0 in gill, liver and brain tissues, whereas only a single peak at pH 7.0 was observed in muscle tissue of both control and MP-exposed fish. The pH 7.0-specific peak was confirmed as aldolase A and the pH 9.0-specific peak represents the tissue-specific aldolases: aldolase B in liver, aldolase C in brain and aldolase B-C in gill. It is further confirmed with the inhibitor sensitivity of aldolases at two peaks with 6 x 10(-3) M ATP or AMP. The pH-based substrate-dependent kinetics of aldolases showed a variable trend. The tissue-specific activity of pH 7.0-specific aldolases showed low Km values for gill followed by muscle, liver and brain tissues, suggestive of its high enzyme-substrate affinity. During MP exposure, the Vmax values of pH 7.0-specific aldolases in muscle, gill and brain were unchanged compared to controls, but Km values were decreased. The pH 9.0-specific aldolases of gill and liver from MP-exposed fish showed decreased Km values with a slight increase in Vmax values. Effectors such as lysine, arginine and Ca2+ inhibited, while histidine, cysteine, aspartic acid and alpha-ketoglutaric acid elevated the activity levels of aldolases.(ABSTRACT TRUNCATED AT 250 WORDS)

The respiratory parameters of a freshwater teleost, Tilapia mossambica Peters, were studied under sublethal intoxication of methyl parathion. The rate of oxygen consumption by whole fish and selected tissues decreased during a 48-hr time-course study. The activities of the respiratory enzymes succinate dehydrogenase, malate dehydrogenase, and cytochrome-c oxidase also decreased considerably under methyl parathion exposure in muscle, gill, liver, and brain tissues. These results suggest that methyl parathion has a profound effect on the oxidative metabolism of the fish which results in low ATP turnover, possibly due to its influence on the respiratory center of the brain.
