At least four phases of deformation are imprinted on the rocks since the sedimentation ( ∼ 2300 Ma) of the metasedimentaries up to the last phase of granitic activity (∼800 Ma). A regional north-south compression was responsible for the development of isoclinal or tight F 1 and F 2 -foIds with nearly east-west axes and overturning towards south. Ultrametamorphism of the older sediments during the acme of F 1 -deformational phase formed the anatectic granitoids and migmatites. Younger plutonic granitoids were emplaced in the axial zones of the F 2 -folds. Nearly east-west compression during the third deformational phase caused north-south trending open type cross folds (F 3 ). Pegmatites and hydrothermal veins were mostly synkinematically emplaced in...

Although GA is a plant growth hormone, it shows a potential to protect the plant in stress conditions. To investigate the possible role of GA in mitigating drought stress, we treated wheat (Triticum aestivum ‘BARI Gom-21’) seedlings with a GA spray under semihydroponic conditions. In the experiment, the combined effect of GA and drought stress (induced by 12% polyethylene glycol) was studied after 48 h and 72 h. In the absence of exogenous GA, drought-stressed wheat seedlings showed various physiological and biochemical changes in a time-dependent manner. Malondialdehyde (MDA), hydrogen peroxide (H2O2) and free proline (Pro) concentrations were increased, whereas catalase (CAT) and ascorbate peroxidase (APX) activities were reduced under drought stress. Gibberellic acid played a role in restoring the ascorbate (AsA) level, decreased the ...

The ANB operation have grown and along w ith it the ANBCC operations have commenced over the last tw o years. This has necessitated moving these divisions to a hired premises in Fern Road. The MBS assessment activities are expanding rapidly and recent initiatives in the Skill Development area and focus on NWTCS activities w ill also require more space. Due to this grow th in activities it was fe lt necessary to acquire bigger accommodation to provide adequate space to accommodate all our activities. As per decision o f Central Council, Building Committee under the Chairmanship o f Mr B. K. Misra, finalized a suitable building fo r the proposed llW-lndia House, situated at 200, Kalikapur Road, Kolkata-99 adjacent to connector o f EM by pass, Kolkata. The final purchase deed was registered by the Registrar o f Assurance on the auspicious day 23rd May, 2013. We are hopeful to Inaugurate the llW-lndia House during AGM. I appeal to all members of the Institute to generously donate money to the Building Fund to enable us to complete the Office renovation.

Every year, the National Welding Seminar provides a common platform far the welding fraternity to meet and exchange the information regarding the latest technological development in India as well as abroad in welding and I wish a great success for this year's event. This Year, the National Welding Meet (NWM-2005) was held at Vishakhapatnam on 23^'* July 2005 organised by our Vishakhapatnam Branch. On behalf of the Central Council, I thank all the members of the Managing Committee-specially Mr. S.V.J. Rao, Hony. Secretary of the Vishakhapatnam Branch for organising this event within a very short time. You will also be happy to note that the first convocation of AM-IIW examination was held at Vishakhapatnam on 24*'' July. Prof. L.

The study aimed at finding out yield and quality response of two varieties of chickpea (BARI Chola-5 and BARI Chola-9), at five different sowing dates viz. November 05, November 20, December 05, December 20 and January 04. The experiment was laid out in a split-plot design with three replications. The results of two varieties revealed significant variations in days to flowering, maturity, number of grains per plant, number of seeds per grain, the weight of 1000 seeds, grain yield, stover yield, biological yield and harvest index due to different sowing dates. Early and delayed sowings affected the chickpea yield and the quality of grain. Physiological responses of chickpea were also greatly influenced by different sowing dates that affect the proper growth and development of chickpea plants. In case of varieties, significant variation was observed in all parameters, here, BARI Chola-9 showed better performance than BARI Chola-5. BARI Chola-9 sown on November 20 produced maximum grain yield (2.40 t/ha) and the lowest grain yield (1.23 t/ha) was found in BARI Chola-5 sown on January 04. Irrespective of variety, early and delayed sowings showed lower performance on all parameters, significantly affected the yield and quality of chickpea.

So, a lab experiment was conducted to find out the effect of various Polyethylene Glycol (PEG) concentrations on the germination behavior of wheat. Wheat seeds of BARI Gom 27 and BARI Gom 28 were pre-soaked in 0, 5, 10, 15 and 20% PEG solution and untreated seeds were served as control. Results revealed that seed priming enhanced germination percentage (GP), vigor index (VI) and germination index (GI) of wheat seed. The highest GP (95.55%), VI (201.00) and GI (43.73) were obtained from seeds of BARI Gom 27 pre-treated with 10% PEG solution compared to BARI Gom 28 (75.55%, 128.71 and 27.12 of GP, VI and GI, respectively) and then decreased gradually with increasing PEG concentration. Therefore, seed priming helps to enhance the germination behavior of wheat seed.

Statistically significant variation was recorded for different growth and reproductive parameters. Results showed that BARI chola 9 gave the highest plant height, number of branches plant-1 , dry matter content plant-1 , pod remaining, pod length, seed yield and the lowest flower dropping, pod dropping, total dropping. Among the supplemental treatments, the highest plant height, number of branches plant-1 , dry matter content plant-1 , pod remaining, pod length, seed yield and the lowest flower dropping, pod dropping, total dropping were found from supplemental irrigation + aqueous N before flowering. In case of treatment combination, the highest plant height (39.31 cm), number of branches plant-1 (6.53), dry matter content plant-1 (7.02 g), pod remaining (39.67 %), pod length (1.96 cm), seed yield (1.94 t ha-1) and the lowest flower dropping (57.27 %), pod dropping (3.07 %), total dropping (60.33 %) was recorded from BARI chola 9 with supplemental irrigation + aqueous N before flowering.

The high speed machining of AISI 1045 using coated carbide tools was investigated. A combined technique using orthogonal array and analysis of variance was employed to investigate the contribution and effects of cutting speed, feed rate and depth of cut on three surface roughness parameters and power consumption. The results showed a significant effect of cutting speed on the surface roughness and power consumption, while the other parameters did not substantially affect the responses. Thereafter, optimal cutting parameters were obtained.
