    Notes: Summary Field experiments showed that soil compaction did not affect wheat yield significantly under rainfed conditions. Weed population was significantly reduced due to soil compaction. Compaction decreased total moisture use and increased water use efficiency. There was better and profitable utilization of stored soil moisture from the compaction treatments as compared to no compaction treatment. Placement of nitrogen about 10 to 15 cm deep in the soil directly below the seed resulted in significant increase in the yield of wheat crop grown under rainfed conditions. Weed population was not affected due to nitrogen placement. Total moisture use reduced due to nitrogen placement. Under rainfed conditions, deep placement of nitrogen was important for increasing the efficiency of fertilizer as well as water utilization by wheat crop.

    Notes: Summary  Changes in the frequency of tropical cyclones developing over the Arabian Sea and the Bay of Bengal have been studied utilizing 122 year (1877–1998) data of tropical cyclone frequency. There have been significant increasing trends in the cyclone frequency over the Bay of Bengal during November and May which are main cyclone months. During transitional monsoon months; June and September however, the frequency has decreased. The results have been presented for five months, i.e., May-November which are relevant as far as tropical cyclone frequency over the Arabian Sea and the Bay of Bengal are concerned. The tropical cyclone frequency in the Arabian Sea has not shown any significant trend, probably due to small normal frequency. The frequency time series has been subjected to the spectral analysis to obtain the significant periods. The cyclone frequency over the Bay of Bengal during May has shown a 29 year cycle. A significant 44 year cycle has been found during November. Over the Arabian Sea significant cycles of 13 and 10 years have been observed during May-June and November, respectively. The tropical cyclone frequency in the North Indian Ocean has a prominent El Niño-Southern Oscillation (ENSO) scale cycle (2–5 years) during all above five months. The annual cyclone frequency exhibits 29 year and ENSO scale (2–4 years) oscillations. There is a reduction in tropical cyclone activity over the Bay of Bengal in severe cyclone months May and November during warm phases of ENSO. Examination of the frequencies of severe cyclones with maximum sustained winds ≥ 48 knots has revealed that these cyclones have become more frequent in the North Indian Ocean during intense cyclone period of the year. The rate of intensification of tropical disturbances to severe cyclone stage has registered an upward trend.

    Description / Table of Contents: Pfropfcopolymere aus Polyacrylamid auf Stärke (S-g-PAM) mit verschiedenen Pfropfgraden wurden hergestellt. Die Dichte dieser Pfropfcopolymeren war niedriger als die von Stärke. Die Pfropfung von Acrylamid auf Stärke unterbricht die körnige Struktur der Stärke und führt zu einer festen und kompakten Struktur. Folien aus verschiedenen Copolymeren und Mischungen aus Stärke und Polyacrylamid wurden durch Preßformen hergestellt. Eine Verbesserung der Zugfestigkeit und der Dehnung wurden an Pfropfcopolymeren beobachtet. Beim zweistündigen Aufheizen auf 100°C verloren die Pfropfcopolymeren einen großen Teil ihrer Festigkeit und Elastizität. S-g-PAM-Copolymere zeigten eine verbesserte Beständigkeit gegen einen Abbau durch α-Amylase.
    Notes: Starch-graft-polyacrylamide (S-g-PAM) copolymers having different graft-on were prepared. The density of these copolymers was lower than that of starch. The grafting of acrylamide onto starch disrupted the granular structure of starch and a tight and compact structure was formed. Sheets of various copolymers and blends of starch and polyacrylamide were prepared by compression moulding. An improvement in tensile strength and elongation was observed in graft-copolymers. When heated at 100°C for 2 h, the grafted sample lost a great deal of strength and elasticity. S-g-PAM copolymers also showed more resistance to degradation by α-amylase.

    Description / Table of Contents: Es wurde das thermische Verhalten von mit Polyacrylamid gepfropfter Stärke untersucht. Das Pfropfen von Polyacrylamid auf Stärke setzt die Ausgangszersetzungstemperatur herab. Jedoch nimmt die allgemeine Stabilität, die durch die Form der thermogravimetrischen Kurven abgeschätzt werden kann, und die integrale Zersetzungstemperatur mit dem Ansteigen des Pfropfgrades zu.
    Notes: Thermal behaviour of starch-graft-polyacrylamide (S-g-PAM) copolymers was evaluated. Grafting of polyacrylamide onto starch lowers the initial decomposition temperature. However, the over-all stability as assessed by the shape of thermogravimetric curve and integral procedural decomposition temperature increased with an increase in % graft-on.

    Description / Table of Contents: Zusammenfassung Es wird über — größtenteils im Labor durchgeführte —Untersuchungen zur Biologie der in Indien an Sojabohne schädlichen EulePlusia acuta Walker berichtet. Eizahl und Eiablageort, Stadien- und Gesamtentwicklung, Veruppungsform, Puppengewicht, Schlupfquote, Lebenszeit und Geschlechterverhältnis der Falter im Labor sowie Parasitierungsquote und Parasiternarten einer Freilandpopulation werden mitgeteilt.
    Notes: Abstract Plusia acuta, hitherto reported as a minor pest of soybeans, now has become its a regular and serious pest in Madhya Pradesh, India. During kharif season of 1979 it infested severely about 10 hectares of soybeans in Jabalpur, Madhya Pradesh, India. Research was, thus, carried out to work out its biology in the laboratory in 1979. Single female moth laid 97.6 eggs in its life span on both the surface of leaves and some times on tender petiole and petiolets. The incubation, larval, prepupal and pupal periods lasted for about 4, 14, 1 and 7 days, respectively. Total life cycle completed in 24.8 days. Male and female moths lived for 5.6 and 4.8 days, respectively. The percentage emergence of adults was 73.8 in the laboratory. 26.3 percent larvae were found parasitized in fields.

    Description / Table of Contents: Zusammenfassung Nachdem der Ringelbock,Oberea brevis Swed. in Indien bisher in 3 Gebieten als Schädling von 5 Kulturpflanzenarten, darunter der Sojabohne,Glycine max, bekannt war, wurden 1975 und 1976 Untersuchungen darüber durchgeführt, ob er noch weitere Pflanzenarten befällt. Als Ergebnis konnten 11 bisher nicht bekannte Wirtspflanzenarten dieses Cerambyciden nachgewiesen werden.
    Notes: Abstract Up to this time the girdle beetle,Oberea brevis has been recorded on soybean (Glycine max), beans (Lab-lab niger), cow pea (Vigna signensis), urid (Phaseolus mungo) and moong (Phaseolus radiatus) growing in the areas of Utter Prodesh, Madhya Pradesh and Jabalpur, India. The pest caused mortalities of plants up to 36.5 per cent. In 1975 and 1976 researchs were done to record the host range ofO. brevis. The infestation was ascertained by having two parallel girdles, which are made by the female beetles to reduce the moisture content of the plant and to lay the eggs between the girdles. Due to girdling on the plants, the apical parts dry and later drop off and larvae make their tunnels in the lower parts of the plants. 11 new host plants ofO. brevis were recorded.

    Notes: Bond orders and hybrid populations have been calculated from the density matrix localized in molecular space using similarity transformation for some fluorobenzene with the minimal basis set using Gaussian series of program. The ab initio bond orders and hybrid populations have been compared with the semiempirical calculations on this set of molecules. Also, these bond orders have been used in Coulson's bond order-bond length relationship to estimate bond lengths. The present calculations suggest that the qualitative predictions of molecular geometries are possible from these bond orders.
