Irrigation for rice cultivation increases the production of Anopheles gambiae, the main vector of malaria in Mali. Mosquito abundance is highly variable across villages and seasons. We examined whether rice cultivation patterns mapped using remotely sensed imagery can account for some of this variance. We collected entomologic data and mapped land use around 18 villages in the two cropping seas...

In 2016–2018, an experiment with Sida hermaphrodita L. Rusby (Virginia fanpetals) called was conducted in the system of random blocks on sandy and loam soil. Each year, yields dry aboveground mass dried roots were determined. Before sowing after end research, composition earthy fractions soils stalks Sida, percentage content determined, carbon calculated. When grown soil, average yield (stalks ...

application of superabsorbent material is one of the new methods for moisture storage in the soil. this research was performed in the khajeh research station on the basis of randomized complete block design with three replications in the plots with dimension of 4×5 meter for investigate the effect of different amounts of pumice on water retention capacity in the soil, growth and of spring saffl...

The cultivation of adult human cells of normal origin has become a routine procedure during the past several years (4). Among the first stable epithelial-like (Ep-L) cell lines derived from nor mal human tissues were those established by Chang (1954) (5) from conjunctiva, liver, kidney, and appendix. Although the HeLa strain of cells from cancer tissue had been available before this time, there...

System of Rice Intensification (SRI) paddy was introduced to offset the heavy cost of Traditional paddy cultivation. To decrease the cost of cultivation in Traditional paddy, to increase profits of the farmers in rice cultivation by decreasing the use of fertilizers, pesticides and minimizing water use by scientific water management in the face of labour scarcity, SRI paddy was introduced in Ma...

Modern biotechnology entered the world science arena after 1972, and in less than 22 years first genetically modified crop was placed on market. The analysis of relevant biosafety portals official scientific documents applied this study to reveal positive negative issues Romanian framework before European Union (EU) accession. success cultivating highly productive GM soybean rapidly embraced by...

1. In a search for suitable tissues for the cultivation of yellow fever virus in vitro, mouse embryos were inoculated with this virus in utero. A titration for virus content of the various organs of the embryos indicated that the virus was present in the brain in greatest concentration. 2. Unmodified strains of yellow fever virus were readily adapted to cultivation in vitro in a medium consisti...

Using a system of whole-embryo culture, the effect of polybrominated biphenyls (PBB) was investigated on the rates of DNA, RNA, and protein accumulation in rat embryos. Embryos were isolated on the 10th gestational day (sperm day = Day 0) either 4 or 24 hr after maternal administration. The cultivation period was for 24 or 42 hr. DNA, RNA, and protein accumulation rates were not affected by a 4...

This is a preliminary study of the depth distribution of (137)Cs radionuclides in cultivated anthrosol soil of a 15-year old peach tree plantation at the experimental field "Radmilovac" near Belgrade. Before planting, the soil was ploughed at the depth of 1 m. The soil had not been annually ploughed, irrigated and treated with mineral fertilizers for three years before sampling. Activity concen...

In-situ soil assessment such as field compaction can often be a helpful approach in help determining suitability for certain crops. In this study, an was conducted to characterize the Soil Penetration Resistance (SPR) planted sago palm (Metroxylon spp.) plantation at different growth of rosette and trunking stages under mineral soils ecosystem. SPR in-situ would provide beneficial guideline sit...
