    Notes: Abstract. This study was undertaken to test the hypothesis that an improved system of catchment management in combination with appropriate cropping practices can sustain increased crop production and improve soil quality of Vertisols, compared with prevailing traditional farming practices. Initiated in 1976, the improved system consisted of integrated land management to conserve soil and water, with excess rainwater being removed in a controlled manner. This was combined with improved crop rotation (legume based) and integrated nutrient management. In the traditional system, sorghum or chickpea was grown in the post-rainy season with organic fertilizers, and in the rainy season the field was maintained as a cultivated fallow. The average grain yield of the improved system over 24 years was 4.7 t ha−1 yr−1, nearly a five-fold increase over the traditional system (about 1 t ha−1 yr−1). There was also evidence of increased organic C, total N and P, available N, P and K, microbial biomass C and N in the soil of the improved system. A positive relationship between soil available P and soil organic C suggested that application of P to Vertisols increased carbon sequestration by 7.4 t C ha−1 and, in turn, the productivity of the legume-based system, thus ultimately enhancing soil quality.

    Notes: Background: Filariasis is an endemic problem in various Indian states. We evaluated the results of long-term follow up (10–20 years) of patients with filarial chyluria.Methods: We conducted a retrospective analysis of 160 patients treated for filarial chyluria who presented to the Banaras Hindu University Hospital from 1982 to 1992. Eighty-four patients (52.5%) were treated using diethylcarbamazine (DEC) and a fat restricted diet and 76 patients (47.5%) underwent surgery. To examine the long-term effects of filarial chyluria we analysed data on post-treatment recurrence, weight gain, dietary freedom, chyluria free period and a number of other associated factors.Results: Previous history of filariasis or its complication was documented in 19% of patients. In 71% of cases, cystoscopy showed that chylous efflux was predominant in the left ureteric orifice. The long-term remission rate was 62% in the conservatively managed group (DEC + fat restricted diet), whereas 90% of patients in the operated group were cured. Postoperative recurrence rate was 10%. There was more weight gain and dietary freedom along with a longer chyluria free period in the operated group relative to the conservatively managed group.Conclusions: Definitive surgical ablation of lymphatic urinary fistula is better than conservative medical management because it has a higher success rate, more dietary freedom and, therefore, better patient acceptability.

    Notes: A 3-year study was made on genetic variability of seed oil content and seed index with 20 wild species, two cultivated species and six perennial races of Gossypium arboreum cotton maintained at the Central Institute for Cotton Research, Nagpur, India. The mean seed oil content varied from 10.26 to 22.89% in 22 species of Gossypium and six races of G. arboreum. In this material the weight of delinted seed varied from 43.33 to 54.54 mg/seed. The highest seed oil content was recorded in the species G. lobatum followed by G. harknessii. On average, for both traits, the means were higher for G. arboreum and its races. However, G. africanum and G. harknessii reached the level of G. arboreum and its races for seed weight, while five wild species surpassed the best races and G. arboreum in seed oil content, among them was G. harknessii. To breed simultaneously for seed oil content and seed weight, crosses between races of G. arboreum and wild species of Gossypium seem to be promising.

    Notes: In this paper we numerically investigate the motion of viscoelastic liquids passing through two-dimensional periodic arrays of cylindrical particles using the finite element method. The viscoelastic liquid is modeled by the Chilcott–Rallison version of the finitely extensible, nonlinear elastic (FENE) dumbbell model. The permeability and the viscoelastic stress distribution are studied as functions of the dimensionless relaxation time De and the dimensionless wave number kD, where k=2π/λ is the wave number, λ is the distance between the particles in the flow direction and D is the cylinder diameter. The porosity and D are held fixed. Our simulations show that for a fixed value of De the viscoelastic permeability increases with kD, but, as is the case for Newtonian fluid [Alcocer, Kumar, and Singh, Phys. Rev. E 59, 711 (1999)], this increase is not monotonic. The permeability decreases between kD(approximate)5.0, where it is locally maximum, and kD(approximate)7.7, where it is locally minimum. The difference between the locally maximum and minimum values of permeability increases with increasing De. When De=O(1) the locally minimum value of the permeability is ∼40% smaller than the value at the local maximum. This implies that a substantial change in permeability can be achieved by changing the distance between the particles in the flow direction while keeping De, D, and porosity fixed. © 2002 American Institute of Physics.

    Notes: The effect of signal modulated optical radiation on the Schrödinger wave function has been studied in a quantum well in a n-AlGaAs/GaAs modulation doped field effect transistor (MODFET) and related device characteristics. Partial depletion of the active region of the modulation doped field effect transistor has been considered. At the heterojunction interface two different models for the quantum well has been assumed: (1) a triangular potential well and (2) a modified triangular potential well of finite depth. From the knowledge of frequency dependent Schrödinger wave function sheet concentration of the two-dimensional electron gas, the drain-source current of the MODFET and the transfer characteristics as a function of signal frequency have been evaluated. The frequency dependent current–voltage characteristics are compared with the published theoretical results since no experimental data are available on similar studies. © 2000 American Institute of Physics.

    Notes: The effect of purified mouse serum amyloid P-component (SAP) treatment of mouse alveolar macrophages (AMs) on their uptake of Mycobacterium tuberculosis Erdman was investigated, in vitro. SAP (0.5–50.0 µg/ml), in a concentration-dependent manner, inhibited the M. tuberculosis uptake by the AMs; maximum inhibition (33.43%) occurred at 10.0 µg/ml. The inhibition of uptake could be observed as early as 30 min after the incubation of AMs with 10.0 µg/ml SAP; however, an incubation of 60 min induced maximum inhibition beyond which the response became static. The SAP-mediated decreased uptake of M. tuberculosis also resulted in their reduced intramacrophage growth as determined by colony-forming unit counts. SAP inhibited the uptake of mycobacteria in the presence of Ca2+, and at pH = 5.6, the inhibition was abrogated. Deglycosylation of purified SAP with N-glycanase, and not with O-glycanase, blocked the SAP-mediated inhibition of the uptake. Heat-inactivated (80 °C; 1 h; pH 7.0) SAP did not inhibit the uptake of M. tuberculosis by AMs. These data, apparently for the first time, indicate that purified mouse SAP, in a divalent cation- and N-linked oligosaccharide glycosylation-dependent manner, inhibited the in vitro uptake of M. tuberculosis Erdman by mouse AMs, which was also associated with their reduced intracellular growth.

    Notes: Purified mouse serum amyloid P-component (SAP; 0.5-50 µg/kg), injected intravenously into Swiss mice, induced the production of serum colony-stimulating factors (CSFs); the maximum induction was observed at 10.0 µg/kg. Further, in vitro purified mouse SAP (0.1-50 µg/ml) stimulated the mouse elicited peritoneal macrophages to elaborate CSFs in the conditioned medium (CM); 5.0 µg/ml SAP appeared to be the optimum. Both in vivo and in vitro the maximum production of CSFs occurred 6 h after initiation of stimulation, and returned to the background levels by 48 h. Mannose 6-P, mannose 1-P and mannose, and not other sugars inhibited the SAP-induced production of CSFs by macrophages which suggests that SAP interaction with macrophages was mediated by specific glycoprotein-receptors. A neutralizing (100%) concentration of rabbit antimouse interleukin (IL)-1 polyclonal antibody had no effect on the SAP-induced CSF production, indicating that it would be IL-1-independent. SAP-induced CSFs, both in serum and CM, were functionally similar as they supported the formation of granulocyte (G), macrophage (M) and GM colonies in similar proportions. The production of CSFs appeared to be lipopolysaccharide (LPS)-independent as it was not inhibited by polymyxin B sulfate (25.0 µg/ml), and heat-inactivated (80 °C, 1 h, pH 7.0) SAP did not induce the production of CSFs. The CSFs were produced de novo because cylcoheximide (50.0 µg/ml) completely inhibited their production. These results demonstrate that purified mouse SAP, in a dose-dependent manner, can induce the production of serum CSFs in mice, and can induce LPS-independent de novo production of CSFs by elicited macrophages in vitro.

    Notes: Abstract: The fission fragment angular distributions have been measured for the system 19F +209Bi over a range of bombarding energies from 88.0 MeV to 125.6 MeV. The measured fission fragment anisotropies are in agreement with the saddle point statistical model calculations in the above energy range. Combining these data with those available for 11B, 12C, 14N, 16O and 18O +209Bi, 208Pb systems, it is concluded that the spherical target plus projectile systems behave “normal” from near- to above – barrier energies. This observation is in contrast to the “anomalous” anisotropies exhibited by the deformed actinide target – projectile systems at near – barrier energies.
