Chaetomium species which are normally found in soil and organic compost are noted for the presence of secondary metabolite with biological activities. Secondary metabolites from culture filtrate of Chaetomium globosum Kunze were extracted by solvent extraction method using ethyl acetate and separated by thin layer chromatography in five major bands of different Rf values. These compounds were further purified and fractioned with column chromatography. Compound '1' eluted with hexane (fraction 1-18) as color less liquid (Rf 0.84), and other five compounds (2,3,4,5,6) with different ratio of hexane, benzene and acetone as solvent in different fractions as: 34-63 (Rf. 0.46), 71-75 (Rf 0.31), 78 (Rf 0.58), 76-77 (Rf 0.58) and 85-89 (Rf 0.47) were eluted and purified. GS-MS and NMR studies revealed that compounds 2-6 were identical to spectral data of metabolites, chaetomin, BHT, mollicelin G, isomer of mollicelin G and cochiliodinol respectively. One more elution with benzene: acetone (95 : 5 v/v) gave a pale yellow crystalline compound of Rf 0.37 identified as chaetoglobosin. Bioassay studies with two compounds i.e., chaetoglobosin and chaetomin revealed significant growth inhibitory activity against various plant pathogens such as Bipolaris sorokiniana, Macrophomina phaseolina, Rhizoctonia solani and Pythium ultimum under in vitro conditions.Keywords

On the basis of detailed field mapping and available gravity data, certain conclusions regarding the mode of eruption of Deccan trap lavas are drawn.
In Kutch, the Deccan trap formation outcrops along the western and southern periphery of the mainland. The trap flows which rest disconformably over the Mesozoic rocks, are also seen to cover the eroded Mesozoic structures. They thin out towards the central and northern hills of folded Mesozoic rocks. Whereas basic dykes and sills are concentrated in these fold zones, a number of plugs occur close to the Deccan trap outcrops. Igneous plugs, seem to be related more to the trap than the tectonism. The dykes and sills are probably syntectonic whereas the trap flows are post-tectonic with respect to the Mesozoic folding. Three volcanic cone-like structures have also been discovered at the fringe of the Deccan trap outcrop, near Jada and Wehar. It is therefore, concluded that the trap lavas in Kutch have mainly erupted from Hawaiian type shield volcanoes. The lavas erupted from such volcanic centres periodically and flowed to the south down the paleoslope towards the main volcanic field.
Positive gravity anomalies are noted around well known plugs of Saurashtra which have long been considered as the eruptive centres along tectonic lines. Similar anomalies which could also be interpreted as the subsurface volcanic plugs or cones, are seen within the major rift zones of Western India like Cambay and Narmada grabens and faulted west coast. Thus, the Deccan trap lavas of Peninsular India too might have erupted from Hawaiian type shield volcanoes situated along the major fracture zones.

Andesite lavas are associated with pyroclastics and a few sheet-like porphyritic flows. The volcanism is considered to have been of mixed eruptions indicating sufficient fluidity and low gas content. The andesitic lavas are characterised by well developed pillow structure. They are interlayered with pyritiferous and carbonaceous argillites indicating volcanic eruption under submarine condition.
The lavas occupy the central part of a major refolded antiformal anticline plunging to the west. They have undergone metamorphism only up to the green-schist facies of regional metamorphism. Carbonatisation of lavas is a common feature, particularly in andesite.

The Sandur schist belt is predominantly characterised by greenschist facies of regional metamorphism, which increases to amphibolite facies near the periphery of the schist belt. The higher facies rocks are marked by the appearance of metamorphic index minerals like garnet, andalusite, staurolite and cordierite. Study of the 'Si - Se' tectonites suggests that metamorphism is progressive, where chlorite and micas grow 'synkinematically' and garnet, andalusite, staurolite and cordierite grow post-kinematically with reference to first phase of folding (F1). Static growth of garnet, andalusite, staurolite etc., following the first phase of folding (F1), and their subsequent rotation with reference to second phase of folding (F2) clearly indicates a time gap between F1 and F2. Formation of assemblages of higher grade metamorphic minerals along the border region of the schist belt, is possibly due to influx of additional heat from some source (? intrusi ve granite) at a late tectonic stage.- A Note on the 'Volcanic Conglomerate'/Pyroclast Horizon near Palkanmaradi in the Hutti Schist Belt, Karnataka

Palkanmaradi 'Conglomerate' occurs as a conformable bed within the volcano-sedimentary sequence of the Hutti schist belt. Well-rounded pebbles of granodiorite/tonalite gneiss, microgranite/acid volcanic rock, angular to subangular fragments of amphibolite, are found embedded in a matrix having unusual chemistry representing probably an admixture of volcanic and sedimentary material. Along with the other rocks tbe conglomerate bed has suffered from three distinct phases of deformation and attained amphibolite facies of metamorphism.- Stratigraphy and Structure of the Sandur Schist Belt, Karnataka

Sandur schist belt comprises predominantly of volcanic rocks with subordinate amount of metasediments. Mineralogy of the clastic sediments indicates a pre-existing sialic crust. The schist belt represents a fracture-controlled basin having an unstable tectonic set-up. Two distinct phases of folding deformation (SD1 and SD2), of which the earlier one (SD1) is quite pronounced producing the NW-SE trending regional structure of the schist belt, are noted. SD1 is associated with the development of macroscopic folds (F1), tight to isoclinal mesoscopic folds (f1 ), schistosity (S1 ), mineral lineation Im), fold mullion (In), and pebble lineation (Ip). SD2 is associated with the development of broad warps (F2) with axial traces along ENE-WSW direction, open to close mesoscopic folds (f2) and crenulation cleavage (S2).- Microfacies Analysis of Limestones

Gold mineralisation, hosted by varied lithounits, is broadly classified into two types. 1) Syngenetic stratabound type, 2) Epigenetic lode type
Syngenetic stratabound type mineralisation, confined to pyritiferous carbonaceous schist, has little economic significance, whereas economic deposits belong to epigenetic type. Epigenetic lode type mineralisation is hosted by both mafic and felsic rocks. Mineralised zones are confined to structural dilatant zones (shear zones) and are characterised by wall-rock alteration. Mineralogical and geochemical changes are most conspicuous.

Turbidimetric assay study of agglutination induced by lectin RCA1, in erythrocyte ghost membranes of several vertebrates and in the liposomes of their polar lipid isolates, demonstrates that glycolipid is one of the major receptors of lectin RCA1, in all these systems. The study also shows that Mg2+, a divalent metal ion enhances this agglutination. whereas the effect of Ca2+ is not so significant in majority of the cases. Reversal of agglutination is studied after addition of galactose to the assay mixture.Keywords

Major and trace (including rare earth)element abundances, mineral compositions and Nd and Sr isotopic compositions have been determined for the mafic dykes (classified as basanite) and gabbro of the northern Island belt of Kutch rift basin. These are petrographically and geochemically distinct but have similar mantle normalized trace element patterns Measured87Sr/86Sr ratios in the mafic dykes vary from 0 70428 to 0 70593 &Nd(i) varies from 0 27 to - 6 5. The isotopic compositions are broadly similar to that of Mahabaleshwar flows of western Deccan volcanic province. The geochemical character suggests the influence of fractional crystallisation in the evolution of the basanite dykes. The parent magma was enriched in K, Ti, Na and P suggesting derivations from an enriched source during the early phase of lifting Palaeomagnetic data on the dykes show the presence of both normal polarity direction at Dm = 338°, Im=-47° and reverse polarity direction at Dm=14l° and Im=34° indicating multiple intrusion Virtual Geomagnetic Pole(VGP) for the basanite dykes differs from Deccan Super pole suggesting a magmatic event older than the main Deccan eruption.Keywords

In this paper an attempt has been made to work out a geological model explaining the cause of earthquake rupture nucleation. Kutch rift is characterised by foothill uplifts and hanging wall half-grabens bound by quasi-vertical faults, which are resurgent primordial faults of Mid-Proterozoic Delhi fold belt. The structural style, tectonic cycles, fault kinematics and seismological data are reviewed to identify the causative fault and the critical zone for repeated earthquakes in Kutch. The Kutch Mainland fault (KMF) along the rift axis is the principal weak zone within the rift. Initiated as normal fault during Mesozoic rifting the near vertical KMF became a right lateral strike slip fault during post-Cretaceous inversion. The fault side steps to the left and continues to the east as the South Wagad Fault (SWF). This SWF is identified as the most active segment for repeated earthquake nucleation. The over step zone between them is a convergent transfer zone and is presently under compressive stress.Two first order basement ridges orthogonal to the rift axis are the unique features of this rift basin: the Median High occurs across the middle of the basin along its hinge zone and Radhanpur-Barmer arch occurs along the eastern rift margin separating it from the N-S Cambay rift. The Radhanpur-Barmer arch along the western rift shoulder of Cambay rift, acts as a ramp for the present northeast-directed compressive stress. Due to this the strain build up in the eastern part of Kutch rift is relatively more than in the western part, west of the Median High. The mounting stress in the eastern part is responsible for repeated thrusting along SWF. Presumably, the SWF would tend to flatten towards a detachment surface close to the base of the seismogenic layer where thrusting is expected. Thus, SWF becomes the active segment (eastern trace of KMF) of the principal fault causing repeated thrust at depth in mid-crustal region. The fading KMF is likely to converge with SWF at dcpth. Aftershock data corroborate this interpretation. The transfer zone where the epicenters of both 1956 Anjar and the recent 2001 Bhuj earthquakes are located close to each other is the critical area for the occurrence of earthquakes. The focal depths (15-20 km) seem to be occurring in the zone of flattening of SWF, which appears to be the critical site for rupture nucleation. Accordingly this segment is interpreted as the vulnerable sire for repeated ruptures causing earthquakes.

The 600 m thick prograding sedimentary succession of Wagad ranging in age from Callovian to Early Kimmeridgian has been divided into three formations namely, Washtawa, Kanthkot and Gamdau. Present study is confined to younger part of the Washtawa Formation and early part of the Kanthkot Formation exposed around Kanthkot, Washtawa, Chitrod and Rapar. The depositional architecture and sedimentation processes of these deposits have been studied applying sequence stratigraphic context.Facies studies have led to identification of five upward stacking facies associations (A, B, C, D, and E) which reflect that deposition was controlled by one single transgressive - regressive cycle. The transgressive deposit is characterized by fining and thinning upward succession of facies consisting of two facies associations: (1) Association A: medium - to coarse-grained calcareous sandstone - mudrocks alternations (2) Association B: fine-grained calcareous sandstone - mudrocks alternations. The top of this association marks maximum flooding surface as identified by bioturbational fabrics and abundance of deep marine fauna (ammonites). Association A is interpreted as high energy transgressive deposit deposited during relative sea level rise. Whereas, facies association B indicates its deposition in low energy marine environment deposited during stand-still period with low supply of sediments. Regressive sedimentary package has been divided into three facies associations consisting of: (1) Association C: gypsiferous mudstone-siltstone/fine sandstone (2) Association D: laminated, medium-grained sandstone - siltstone (3) Association E: well laminated (coarse and fine mode) sandstone interbedded with coarse grained sandstone with trough cross stratification. Regressive succession of facies association C, D and E is interpreted as wave dominated shoreface, foreshore to backshore and dune environment respectively.
Sequence stratigraphic concepts have been applied to subdivide these deposits into two genetic sequences: (i) the lower carbonate dominated (25 m) transgressive deposits (TST) include facies association A and B and the upper thick (75m) regressive deposits (HST) include facies association C, D and E. The two sequences are separated by maximum flooding surface (MFS) identified by sudden shift in facies association from B to C. The transgressive facies association A and B represent the sediments deposited during the syn-rift climax followed by regressive sediments comprising association C, D and E deposited during late syn-rift stage.

The inventory of materials constitutes the most significant part of current assets and working capital in any organisation. A small saving in the inventory will mirror a crucial edge in benefit of the organisation. In Bangladesh, the retail shops generally face two types of inventory related problems which are either stock-out or overstock. As a result, most of the shops fail to maintain their product availability with lowest possible inventory cost. Through proper inventory control techniques, probability of stock-out as well as overstock situations in the retail shops can be minimised. The present paper is a case study of different inventory control techniques for efficient inventory management system of a retail shop of Bangladesh. The sole purpose of the study is to provide a guideline for inventory managers that will help them to ensure product availability at right quantity as and when required. Relevant data were collected from a renowned retail shop, namely, Pran RFL group, Bangladesh. This real case demonstration will certainly help the future researchers as well as the Bangladeshi manufacturers to maintain proper control & management of inventories.Keywords

Bank protection structures represent a widespread topology of hydraulic structures along the river course. There construction is usually planned along torrent stretches with bank erosive problems that can produce instability conditions both on natural, artificial banks and steep slopes. Many times, the construction of strong bank protection structures is required to defense the urbanized areas or to stabilize landslides. Construction of such interventions causes a substantial modification of the natural aspect of river banks with the partial or complete destruction of the ecological conditions and the reduction of the biological diversification of the riparian habitats. Recently, the application of bioengineering techniques has favored the planning of protective structures with lowered environmental impact. These have been applied in such basins where not extreme erosive action of the flowing water can be controlled with such soft interventions. Bioengineering criteria are usually applied together with the planning of the transverse hydraulic section with a diversified morphological profile that favors the creation of different riparian habitats for faunal and floral living species.

Experiments were conducted to study integrated approach in the management of potato blight. The result showed that T1 treatment (soil application of FYM @ 125gm/pot + waste of mushroom cultivation with Trichoderma harzianum @ 5gm/kg + tuber treatment with Azotobacter @ 5% + foliar spray with Ridomil @ 0.25%) was the best to show minimum disease severity, representing 9.16% as against 76.40% in case of control at 21 days of observation. The treatment also exhibited increased tuber germination and plant height of potato showing the value 100 per cent and 44.5 cm at 30 days age of plant. The maximum number of large size tuber and total yield with 668.6g was also recorded from treatment T1. Thus, integration of FYM + mushroom waste as soil application + bio formulation as tuber treatment + fungicides as foliar spray can be efficiently applied for management of late blight and also get enhanced yield of potato.
