    Notes: Summary A numerical model is developed to solve kinematic wave equations of border irrigation. This model accommodates transient infiltration, which may be defined by any of the well known infiltration models. Test runs, performed using different incremental values of time and space, were found to give results within 5% of one another, thus showing the stability of the numerical model. The conservation of volume of water was satisfied within 1% error at different values of time and space. Three sample data sets from field experiments were used to analyze the numerical model.

    Notes: Summary The iron storage ferritin light-chain gene exhibits multiple restriction enzyme fragments which have been mapped by analyzing sorted human chromosomes. A dual laser chromosome sorter was used to construct spot-blot filter panels representing 22 chromosome fractions. Hybridization of radiolabeled human ferritin-L gene probe to spot-blot panels revealed the ferritin-L gene on more than one chromosome. Miniaturized restriction enzyme analysis was used to map each of the ferritin-L restriction fragments uniquely to one of three chromosomes. This combination of sorted chromosome analyses provides a rapid method to map homologous DNA sequences located on more than one chromosome.

    Notes: Summary The breeding systems of seven Limanthes (Limanthaceae) populations, including one “inbreeding” and three “outbreeding” taxa, were quantified using a multilocus outcrossing rate estimator (tm) and autofertility estimates. Along with the assays of heterozygosity levels, these data were used to separate components of “effective” outcrossing in terms of Wright's equilibrium inbreeding coefficient (Fe) and adult (FA) and zygotic (FZ) fixation indices. The patchy distribution of alleles as a potential source of “substructure inbreeding” was tested from the allelic frequencies mapped along a linear transect. Evidence for consanguineous matings in restricted neighborhoods and for selection at two different life cycle stages, and the efficiency of the protandrous breeding system were noted and discussed. Multilocus estimates of outcrossing are useful for their greater precision and unbiased nature while single locus estimates can help in detecting the effects of selection and population substructure. The data generally support the “heterozygosity paradox” noted by Brown (1979) but further suggest that the paradox may often result from a lack of precision of outcrossing estimates and from overlooking the stages of the life cycle being sampled.

    Notes: Abstract Quantitative understanding and prediction of theprocesses of runoff generation and its transmission to theoutlet represent one of the most basic and challenging areasof hydrology. Traditional techniques for design floodestimation use historical rainfall-runoff data for unithydrograph derivation. Such techniques have been widelyapplied for the estimation of design flood hydrograph at thesites of gauged catchment. For ungauged catchments, unithydrograph may be derived using either regional unithydrograph approach or alternatively GeomorhologicalInstantaneous Unit Hydrograph (GIUH) approach. The unithydrograph thus derived may be used for the simulation offlood events for the ungauged catchments. In this study Gambhiri dam catchment located inRajasthan, India is selected for applying this approach. Gambhiri river is a small tributary of the Berach/Banasriver of the Chambal basin in Rajasthan, India. Theobjective of the present study is to apply GeographicalInformation System (GIS) supported GIUH approach for theestimation of design flood. A mathematical model has beendeveloped at the National Institute of Hydrology, whichenables the evaluation of the Clark Model parameters usinggeomorphological characteristics of the basin. This modelhas been applied for the present study.From this study it is observed that the peakcharacteristics of the design flood are more sensitive tothe various storm pattern as well as method of criticalsequencing followed for the computation of design stormpatterns. Earlier estimates for the peak and time to peakhydrograph was 9143.74 cumec and 18 hrs. respectively.However, the estimates for the peak characteristics ofdesign flood hydrograph obtained from the GIUH basedapproach are 11870.6 cumec and 19 hrs. respectivelyconsidering the same design storm pattern.

    Notes: Abstract To meet raw material requirements, Wimco, the biggest manufacturer of matches in India, has been promoting poplar-based agroforestry through an agroforestry project since 1984 approved by the National Bank for Agricultural and Rural Development (NABARD) in the northern region of India. This study aims at evaluating the performance of poplar-based agroforestry in terms of income, employment and environmental impact from the farmers' perspective. Poplar-based agroforestry is economically viable and more profitable than many of the crop rotations followed in the study area. This land-use system is also capable of providing employment opportunities on farms. Sensitivity analyses indicate that this system is not highly risky. However, costs charged by Wimco for technical advice substantially reduce the income from poplar plantation. With agroforestry experience, farmers can expect high dividends in subsequent rotations. Life-time matrices developed through group interviews are useful for thorough economic analyses of agroforestry projects, particularly in cases where data over a period of time are not available.

    Notes: Abstract A condition on preferences called strict Latin Square partial agreement is introduced and is shown to be necessary and sufficient for quasi-transitivity of the social weak preference relation generated by any special majority rule, under the assumption that individual preferences themselves are quasi-transitive.
