Abstract

An orientation course was conducted to sensitise teachers to emotional problems of children. One hundred and eleven teachers were given a brief orientation course on causation, identification and referral of behaviour and emotional problems, poor school performance, psychosomatic illness, speech disorders, epilepsy and psychoses amongst school children. An evaluation of information gained and of counselling potential of the participants was conducted by comparing their performance on specific parameters before and after the course. The trainee teachers showed significant gain in information. Their counselling potential as rated by four independent raters also showed significant improvement. The study highlights the rationale and methodology of one of the methods for detecting potential mental health workers.

Abstract

After laying the foundation of Indian School Psychology Association (InSPA) in collaboration with the experts of International School Psychology Association (ISPA) in 2011, it occurred to the coordinator of these meetings P. Ramalingam to engage the experts from the two associations to impart first-hand training to school administrators and school counsellors in India. Sarva Shiksha Abhiyan (SSA), an ambitious project of the Government of India to universalize elementary education, provided the most suitable platform in various ways. Training modules were prepared on international guidelines so as to suit to the Indian context. There were 60 participants in the training: 15 higher secondary school principals and 30 high school head masters of the Union Territory of Puducherry, and 15 school counsellors and teachers from various parts of India. They had the opportunity to acquire knowledge in various aspects related to School Psychology, such as building capacity, developing shared vision between the school administration and the teacher, along with the need to provide primary, secondary and tertiary prevention. Focus was on skills in School Psychology, lecture cum interaction, demonstration and role play, skill practice and material preparation, practice workshop with primary and secondary school children, assignments and tests. Interactive technical sessions were scheduled for five days and the feedback received from the participants of this innovative international collaboration was highly satisfactory. There was so much enthusiasm in the community that a School Psychologist Training Institute has been envisioned to conduct such programmes regularly to advance the cause of School Psychology.

Abstract

In this study, chitosan was extracted from fresh water crab Paratelphusa hydrodromous shells. In order to determine physico-chemical characteristics of the extracted chitosan, the yield, water and fat binding capacities were measured. In addition, the antibacterial activity of chitosan against Yersinia ruckeri fish pathogenic bacteria was investigated in this study. The results showed that chitosan solution at 0.5 g/kg markedly inhibited the growth of Yersinia ruckeri fish pathogenic bacteria. The results of the study indicate that crab shells are a rich source of chitosan as 38.23 of the shell's dry weight is consisted of this material. Extracted chitosan were exhibited a lower molecular weight and higher water and fat binding capacities Overall, the results indicated that chitosan was a potential bactericide against bacterial fish pathogen yersinia ruckeri.

Abstract

Objective: The present study was undertaken to investigate the glucose reducing level by Asystasia gangetica flowers with various doses (125, 250 and 500 mg/kg bw) in normal and streptozotocin induced diabetic rats. Methods: Acute and sub-acute toxicity of A. gangetica was evaluated in rats with various doses and its and serum parameters were analyzed. Diabetes was induced by giving streptozotocin (45 mg/kg bw) to the rats and after conformation of diabetes, A. gangetica flower ethanol extract (AGFEE) was administrated to the normal and diabetic rats for a period of 14 days. Body weight and glucose levels were determined after 7^th and 14^th day of the study. Glucose tolerance test was also carried out after administration of glucose at the rate of 2 g/kg bw till 14^th day. Results: The LD₅₀ of extract found to be higher than 2000 mg/kg bw and the extract did not show any significant changes in serum parameters. In blood glucose reducing activity the three doses showed significant lowering glucose levels, when compared with each doses at the dose of 250 mg/kg bw the AGFEE showed maximum activity. In diabetic control rats there was a significant elevation in blood glucose levels and reduction in body weight was produced and continued till the end of the study. No alterations were found in control and extract alone treated rats. Results showed AGFEE had exhibited significant hypoglycemic (glucose lowering) activity. Conclusion: Present in vivo model indicating that the plant extract contain active principle compound for the management of hyperglycemia.

Abstract

he basal quartz-pebble conglomerate of Dhanjori Group of Singhbhum-Orissa craton is characterised by a distinct heavy mineral assemblage of pink zircon, chromite, pyrite, monazite and rutile-silicate intergrowth. Statistical analysis of morphometric features of zircons shows that they are significantly different from those found in Older Metamorphic Group and Older Metamorphic Tonalite Gneiss, but they have resemblance to those found in Singhbhum Granite. The trace and REE characteristics of the conglomerates, and the morphology and chemistry of zircon, identify the Singhbhum Granite Complex as the predominant source rock. At the same time, abundant detrital chromite, the positive trend of Cr-Ni and Cr-Co plots, and high Cr/Th ratios of the QPCs suggest a mixed provenance with an ultramafic component ofkomatiitic affinity (older greenstones) in the granite complex. The relative proportion of older greenstones was higher towards western and southern margins of the Dhanjori basin.

Abstract

A number of zircon separates from-various localities of India were analysed for their uranium, thorium and lead contents. Uranium and thorium were analysed by neutron activation, and lead by anodic stripping methods respectively. Thorium, uranium and lead were found to vary between 60-250, 60-900, 8-90 ppm, respectively. The Th/U ratios are found to be in conformity with the accepted values for granitic or pegmatiticzircon. The elemental abundances have been used to calculate their chemical ages and the values compared with those reported in literature. The ages obtained in this study range from 400-800 m.y. These ages are comparable with the previous reported values.

Abstract

Zircon separates from a few whole rocks and sediments along with the parent sources have been analysed for Zr, Hf, Se, REE, Th and U concentrations by the neutron activation analysis technique. The major, minor and trace analyses of rock samples and their modal analyses are also presented. The chondritic normalised REE patterns of rock samples show positive Eu anomalies, while the zircon samples show negative Eu anomalies. The data have been used to explain the genetical relationship among the rocks under study. This study supports the hypothesis proposed from this laboratory that the detrital zircons of Kerala beach are time integrated cumulates from the whole-rocks of this region. The scandium data indicate the paragenetic sequence of crystallization of zircons in relation to cpx and magnetite.

Abstract

The Precambrian ultramafic-mafic plutonic complex of Nuasahi, Orissa in the Eastern Indian Shield represents at least three suites of magmatic intrusion: (i) an interlayered sequence of enstatitite, websterite (± olivine), dunite, chromitite, harzburgite and orthopyroxenite; (ii) massive gabbroic suite with minor bodies of norite, anorthosite and bands of titaniferous magnetite and (iii) dykes and sills of dolerite and clinopyroxenite. A prominent breccia zone is developed near the interface of the first and second magmatic suites in the eastern part of the complex including the Shankar chromite lode and the ultramafic host of the first suite, and the gabbro-noritic rocks of the second suite. This breccia zone is enriched in Cu-Fe-Ni sulphides and has become the principal site for concentration of PGE, gold and silver. On a whole, Pd dominates over Pt in the sulphide-bearing Shankar chromite lode and the adjacent orthopyroxenite as well as gabbro in this breccia zone. The chromite-sulphide association is the most enriched part for PGE, gold and silver. Ag is positively correlated with Pd. The breccia zone which was developed prior to the gabbroic emplacement into the chromiferous ultramafics. represents a sulphide-rich metasomatic zone leading to maximum concentrations of PGE, Au, Ag in this zone alongwith formation of various sulphides, oxides and silicates. Both Pt and Pd are considerably higher and Ir is lower in the present area than in chromite-sulphide associations from ophiolitic complexes and Alpine-type massifs. Rather, Pt, Pd and Ir values compare better with the chromite-sulphide associations from layered intrusions.

Abstract

The granulitic terrain of Proterozoic Delhi Supergroup exposed between Balaram and Mawal in Gujarat carries a suite of plutonic basic intrusive rocks consisting of gabbro, norite and basic granulites. Chronologically the suite is younger than metabasic rocks of north and central Rajasthan and occurs as melt intrusion within the host of pelitic granulites, calc granulites and granite gneisses. The suite ranges in chemical composition from alkaline to tholeiite through calc alkaline with characteristic major elemental distribution. Rare earth element chemistry shows Eu anomaly with LREE and LILE enrichment over HREE and HFSE. On the basis of the above enrichment it is invoked that the rocks are possibly derived from an enriched mantle beneath a subduction zone. Further, the Hf / 3-Th-Ta and Th / Yb-Ta / Yb systematics reflect a compositional match with calc alkaline basalt of present arc setting. These lead to suggest that the gabbro-norite-basic granulite suite signifies continental are magmatism in Delhi Supergroup and the Aravalli mountain had been evolved through continental collision and subduction during upper Proterozoic time.

Abstract

The Iow level of labour use in Indian agriculture compared with some of the Asian countries and the differences in the intensity of labour use across regions and crops, have evidenced the argument that Indian agriculture Is capable of using more labour than what it presently does. A considerable amount of empirical studies has been carried out on this subject. However, the differences in time span covered, methodology adopted and choice of crops and regions, render the conclusions reached by them of limited significance to other areas and crops. Using the cost of cultivation data, this paper attempt to bring out the determinants of labour demand In paddy cultivation In Tamil Nadu.

Abstract

Significant increase in the productive use of labor in crop production is a pre-requisite for rural transformation in economies like India. This conclusion is based on (a) the population size (b) the inability of the non-agricultural (secondary and tertiary) sector to absorb the ever increasing workforce and (c) a high workforce concentration in the agricultural sector.

Abstract

The free radical scavenging activity of Thespesia populnea bark (TPBE) and leaves (TPLE) has been studied using the methanolic extracts. In vitro antioxidant potential of leaves and stem bark were evaluated in three different models viz superoxide radical scavenging activity, lipid peroxide radical scavenging activity and hydroxyl radical scavenging activity. The two methanolic extract were prepared with different concentration from a maximum of 400μg to minimum of 50μg. All extract have different level of antioxidant property. In comparison, the antioxidant scavenging activity in hydroxyl radical was higher, In super oxide radical was moderate and lesser in lipid peroxide radical. These observations confirm that methanolic extract of Thespesia populnea bark and leaf have different polyphenolic constituent and its importance in antioxidant activity.
