Uncovering consistencies in Indian rainfall trends observed over the last half century por Lacombe, Guillaume, McCartney, Matthew P.

“…Trends in Indian rainfall records have been extensively studied but the subject remains complicated by the high spatiotemporal variability of rainfall arising from complex atmospheric dynamics. For various reasons past studies have often produced inconsistent results. …”

Managing salinity in the Indus Basin of Pakistan por Qureshi, Asad Sarwar, Sarwar, A.

“…Lack of coordination among federal and provincial governments, research institutes, and national and international organizations; conventional farming and irrigation methods used by farmers; limited attention to reclamation and saline agricultural approaches; and lack of resources are some of the reasons for the low success rate. A more concerted effort that includes a greater focus on saline agriculture, capacity building of farmers, and promotion of local interventions to improve self-reliance is necessary for the management of salinity in the Indus Basin. …”

Predicting discharge and sediment for the Abay (Blue Nile) with a simple model por Steenhuis, Tammo S., Collick, A.S., Easton, Z.M., Leggesse, E.S., Bayabil, H.K., White, E.D., Awulachew, Seleshi Bekele, Adgo, E., Ahmed, A.A.

“…The ratio of direct runoff to total flow is used to predict the sediment concentration by assuming that only the direct runoff is responsible for the sediment load in the stream. There is reasonable agreement between the model predictions and the 10-day observed discharge and sediment concentration at the gauging station on Blue Nile upstream of Rosaries Dam at the Ethiopia-Sudan border.…”

Cloning of the complete DNA genomes of four bean-infecting geminiviruses and determining their infectivity by electric discharge particle acceleration por Gilbertson, R.L., Faria, J.C. de, Hanson, SF, Morales, Francisco José, Ahlquist, P.G., Maxwell, D.P., Russell, D.R.

“…Four isolates of bipartite bean-infecting geminiviruses (bean golden mosaic geminivirus isolates from Brazil [BGMV-BZ], Guatemala [BGMV-GA], and the Dominican Republic [BGMV-DR]; and bean dwarf mosaic geminivirus from Colombia [BDMV-CO]) were cloned; full-length cloned double-stranded DNA components A and B of each isolate were not infectious when mechanically coinoculated onto bean primary leaves by surface abrasion but were infectious when coinoculated into radicles of beans (Phaseolus vulgaris) by electric discharge particle acceleration. …”

Milk recording and herd registration in Ethiopia: An essential step towards genetic improvement for milk production por Tegegne, Azage, Redda, T., Gebre-Wold, A., Ketema, H.

“…Genetic improvement for productive traits in livestock, particularly in cattle, has been very slow and insignificant in the country. One of the main reasons for this is lack of well-organized and usable recorded information on the performance of both the indigenous and crossbreds with exotic genotypes to undertake structured selection and breeding programmes. …”
