African Water: Supporting African involvement in the EU Framework Programme.
Water researchers in developing countries have yet to take full advantage of the funding and collaborative research opportunities presented by the EU Framework Programme. There are a variety of reasons for this, such as insufficient information and a lack of previous experience. The African Water initiative aims to increase the involvement of African water researchers through a range of activities including communication and dissemination, capacity building and development, and complementary initiatives. The project has demonstrated that there is a demand for such sector-specific support activities. However, African Water is a small component of a much larger process of partnership between the developed and the less-developed countries of the world, involving many different European and African organisations working across political, institutional and technical domains, and complementing the wide range of actions already being undertaken
Evaluation of innovative cotton genotypes against insect pest prevalence, fiber trait, economic yield and virus incidence in Pakistan
Cotton (Gossypium hirsutum)
is known as important commodity globally.
The experiment was conducted at Cotton
Research Station, Multan, Punjab-Pakistan,
to evaluate resistance of nine innovative
cotton cultivars against insect pest
complex were used along with their
fiber traits, economic yield and virus
incidence. Population of jassid, whitefly
and thrips was recorded by using leaf
turn method, bollworms by counting whole
fruiting parts (buds, flowers and bolls), virus
by counting healthy and virus effected
plants per plot, yield of seed cotton was
determined by hand harvesting method,
while qualitative fiber properties were
measured through HVI spectrum-1 (high
volume instrumentation) method. Cotton
genotype NIAB-Bt-2 is resistant to jassid,
whitefly and thrips with maximum GOT,
staple length. In case of bollworms, all
genotypes are resistant to spotted and
american bollworm, except FH-142 and
MNH-988. No genotype is resistant to pink
bollworm in leftover bolls. Best yield
performance was recorded on FH-142
(2041.54 kg/ha) with minimum CLCuV
incidence. Further our research should
recognize the share of one pest species on
the yield and fiber quality of cotton by
managing other pest species to define better
management strategies. Our studies
concluded that the genotype NIAB-Bt-2 has
less insect attack i.e., sucking pest as well as
bollworms, virus and other fiber
characteristics like GOT, staple length as
compared with other cotton genotypes
should be recommended for general
cultivation and being a resistant germplasm
it should be included in breeding program
for the development of new cotton strains
Studies on biology and antibiosis resistance in mango (Mangiferae indica) varieties against mango mealy bug, Drosicha mangiferae green (Hemiptera: Margarodidae)
Mango is known as king of fruits. Among mango pests, mango mealy bug, Drosicha mangiferae (MMB), is considered one of the most destructive pests of mango orchards and other plantations. Whenever it enters in any orchards it is difficult to eradicate it from those orchards. The experiment was conducted at Entomological Research Sub Station, Multan-Punjab, Pakistan, during 2009 and 2010, to evaluate fitness of mango mealy bug on different varieties of mango and biology on ‘Chaunsa’ variety. Mango mealy bug, Drosicha mangiferae Green (Hemiptera: Coccoidea: Margarodidae), is matter of concern, as it is widespread pest of woody plants even in urban areas. A study was conducted on cultivar resistance and fecundity of mango mealy bug. The ‘Chaunsa’ cultivar of mango proved highly susceptible to mango mealy bug with maximum number of eggs laid, i.e. 335.90, and maximum weight, i.e. 0.239 g of the female, was recorded on the cultivar ‘Chaunsa’. The maximum length, i.e. 1.63 cm, and width, i.e. 0.80 cm of female, was observed on ‘Chaunsa’, which showed a susceptible response and did not differ significantly with the width of female on ‘Black Chaunsa’. Regarding biology, the 1st instar male and female duration on an average is 56.3 days, whereas the 2nd instar has 26 days. In case of the 3rd instar, female has duration 19.5 days and male has three days. Male has pupal stage, while it is absent in female. On an average two study years, the ranking of susceptibility of mango cultivars was as under: ‘Chaunsa’ > ‘Black Chaunsa’ > ‘Malda’ > ‘Fajri’ > ‘Retaul-12’ > ‘Langra’ > ‘Sensation’ > ‘Sindhri’ > ‘Dusehri’ > ‘Sufaid Chaunsa’ > ‘Anwar Reutul’ and > ‘Tukhmi’
Strange stars in Krori-Barua space-time
The singularity space-time metric obtained by Krori and Barua\cite{Krori1975}
satisfies the physical requirements of a realistic star. Consequently, we
explore the possibility of applying the Krori and Barua model to describe
ultra-compact objects like strange stars. For it to become a viable model for
strange stars, bounds on the model parameters have been obtained. Consequences
of a mathematical description to model strange stars have been analyzed.Comment: 9 pages (two column), 12 figures. Some changes have been made. " To

Effect of last cutting dates on seed production of multicut MB-87 – a variety of pearl millet, Pennisetum Glaucum (Bajra)
Pearl millet (Pennisetum
glaucum) is considered an important kharif
crop, which is grown extensively in the
arid and semi-arid tropical regions, where
other crops, like sorghum and maize, fail to
produce economic yields. Its grains are
valued as human food, while its dry stover
makes significant livestock ration in croplivestock
farming system. Pearl millets
(MB-87), a newly developed variety of
Fodder Research Institute, Sargodha,
Pakistan, is one of the best pearl millet
variety, which gives more than one cutting
and helps to cope with fodder lean period,
as well as more income can be generated in
addition to seed. So, overcome the scarcity
period the study was conducted to check the
effect of last cutting dates on seed
production of multicut pearl millet MB-87
was conducted at Fodder Research Institute,
Sargodha, Pakistan, during 2015 and 2016.
Following parameters were taken in to
consideration, i.e. plant height (cm), stem
thickness (cm), number of leaves per tiller,
number of tillers per plant, green fodder
yield (t/ha), length of head (cm), 1000
grains weight (g) and grain yield (kg/ha).
The results depicted that grain yield, i.e.
319.20, was maximum and head length was
highest, i.e. 35.13 cm on 20th of August
having last date of cut, whereas all others
parameters were found to be nonsignificant.
Multicut bajra gives three
cutting of fodder, followed by seed, as
compared with conventional bajra, which
gives only one cutting or seed. Therefore, it
is more economical for the growers of
fodders to grow the pearl millets MB-87 as
fodder, as well as for seed purposes. So, it is
concluded that for gaining maximum grain
yield of multicut pearl millet MB-87 the last
cutting date should be 20th of August. In
future, pearl millet is likely to play a larger
role in providing food and nutritional
security
Effects of individual, household and community characteristics on child nutritional status in the slums of urban Bangladesh
Background Bangladesh urban population is expected to overtake rural population by 2040, and a significant part of the increase will be in slums. Wide disparities between urban slums and the rest of the country can potentially push country indicators off track unless the specific health and nutrition needs of the expanding slum communities are addressed. The study aims at describing the individual, household and community determinants of undernutrition status among children living in major urban strata, viz. City Corporation slums and non-slums, in order to understand the major drivers of childhood undernutrition in urban slum settings. Methods Data are derived from Bangladesh Urban Health Survey conducted in 2013. This survey is a large-scale, nationally representative of urban areas, household survey designed specifically to provide health and nutrition status of women and children in urban Bangladesh. Results Data showed that 50% of under-5 children in slums are stunted and 43% are underweight, whereas for non-slums these rates are 33 and 26% respectively. In terms of severity, proportion of under-5 children living in slums severely underweight or stunted are nearly double than the children living in non-slums. Logistic analyses indicate that mother’s education, child’s age, and household’s socio-economic status significantly affects stunting and underweight levels among children living in the urban slums. Logistic models also indicate that all individual-level characteristics, except exposure to mass media and mother’s working outside home, significantly affect undernutrition levels among children living on non-slums. Among the household- and community-level characteristics, only household’s socioeconomic status remains significant for the non-slums. Conclusions Poor nutritional status is a major concern in slum areas, particularly as this group is expected to grow rapidly in the next few years. The situation calls for specially designed and well targeted interventions that take into account that many of the mothers are poorer and less educated, which affects their ability to provide care to their children
